Definitions

  • the invention relates to a control switch for operating a crane according to the preamble of claim 1.
  • Such a control switch is known from the brochure "CLX CHAIN HOIST - CRANE FOR EVERYDAY LIFTING" from Konecranes.
  • This control switch is designed as a wired pendant control switch and comprises an elongated housing extending in its longitudinal direction.
  • Several operating elements are arranged on a front side of the housing in order to control various functions of a crane which can be connected to the control switch.
  • four control elements designed in the form of buttons and intended for crane and trolley travel are combined in a cruciform arrangement to form a substantially diamond-shaped first control panel.
  • this cruciform arrangement there is a second control panel with two further button-shaped control elements, which are provided to control a lifting mechanism for lifting and lowering a load.
  • the controls for the hoist are arranged one behind the other in the longitudinal direction of the housing and in this respect vertically one above the other.
  • a third control panel is provided, above which an emergency stop button with an actuation direction oriented perpendicular to the front is arranged.
  • the opposite longitudinal sides of the housing which delimit the front, have a parallel course to one another in the area of the first control panel and, in the area of the second and third control panel, in addition to the emergency stop button, their otherwise constant distance only in the area of the second control panel and in the area between the first and the second control panel is reduced.
  • the long sides of the housing in the area of the second control panel jump back relative to their course in the area of the first and third control panel and the emergency stop button and in this respect towards one another, the transitions of the long sides between the first and second control panel each having an oblique course exhibit.
  • control switch for operating a crane is known, the control elements arranged on its housing are arranged in pairs next to one another and in a row with one another with respect to the longitudinal direction of the housing.
  • the object of the invention is to further develop a generic control switch such that it has improved ergonomic properties for particularly comfortable and safe crane operation.
  • a control switch for operating a crane which comprises a housing extending in a longitudinal direction, on the front side delimited by two longitudinal sides of which a first control panel with at least one control element is arranged, in particular for controlling at least one drive for horizontal crane movements, whereby on the Front of the housing, a second control panel with an emergency stop button and a third control panel with two controls, in particular for controlling vertical crane movements, are arranged, in terms of its ergonomic properties for a particularly comfortable and safe crane operation by improving that the long sides in the area of the first control panel have a curve that is biconvex to one another in the longitudinal direction of the housing and thus, in particular, curved outward.
  • the correspondingly biconvex curved longitudinal sides in the area of the first control panel viewed in the longitudinal direction of the housing, extend away from the longitudinal direction and then again towards the longitudinal direction.
  • the first control panel can be diamond-shaped in particular.
  • the first control panel comprises at least two control elements which are arranged one above the other along a longitudinal axis of the first control panel running parallel to the longitudinal direction of the housing and / or alongside one another along a transverse axis of the first control panel running transverse to the longitudinal direction of the housing.
  • a vertex of each of these - from the outside, convex and in this respect biconvex to each other - curved, in particular rounded, sections of the long sides is located at the level of the at least one control element or at the level of the control elements arranged alongside one another along the transverse axis and / or at the level of the between the transverse axis extending along the longitudinal axis of the control elements.
  • the apexes are consequently at the level of the corners of the diamond-shaped first control panel opposite one another in the transverse direction of the housing.
  • the first control panel can also be reached particularly well by the thumb of the hand of a person operating the control switch in the area below the biconvex course of the long sides.
  • the first control panel is designed in particular in such a way that up to four control elements for horizontal crane movements or for controlling the at least one drive for the horizontal crane movements, in particular a crane travel and / or trolley travel of the crane, cross-shaped on the, in particular diamond-shaped, first control panel within the control panel can be arranged.
  • each control element of the first control panel - as will be described in more detail with reference to the figures - is arranged in a corner of an imaginary rhombus of the diamond-shaped first control panel, the intersecting diagonals of this rhombus of the longitudinal axis and transverse axis of the correspond to the first control panel, of which the longitudinal axis is parallel and the transverse axis is corresponding are aligned transversely to the longitudinal direction of the control switch or its housing.
  • the first control panel has only one control element for horizontal crane movements or for controlling the crane travel and / or trolley travel or associated drives
  • the multifunctional control element in particular can thus also be arranged centrally between the long sides and in particular on an intersection of the diagonals of the imaginary diamond. In this case, however, no control elements are arranged in the corners of the imaginary diamond.
  • the control switch or its housing including the courses of the long sides, the arrangement of the control panels and the associated control elements, has a mirror-symmetrical shape with respect to an imaginary plane that is perpendicular to the front and contains the longitudinal axis direction of the control switch or its housing. Due to the mirror symmetry, the control switch can be gripped and held comfortably and securely by left-handed and right-handed people in the same way.
  • a second control panel with an emergency stop button and a third control panel with two control elements are provided on the front of the housing between the long sides.
  • the control elements of the third control panel can preferably be used to control a drive for vertical crane movements, in particular a hoist, of a crane that can be connected to the control switch.
  • the first control panel is preferably arranged between the second control panel and the third control panel.
  • the third control element preferably comprises two control elements for a lifting mechanism of the crane, which are arranged one behind the other in relation to the longitudinal direction of the control switch or its housing.
  • This configuration makes it possible to operate a crane in a particularly ergonomic and at the same time particularly intuitive manner, as a result of which safety in crane operation can be further increased.
  • the control elements of all control panels are preferably designed as buttons, in particular as push buttons.
  • the long sides of the housing also have a biconvex curve in the longitudinal direction of the housing in the area of the second control panel.
  • the longitudinal sides in the region of the second control panel viewed in the longitudinal direction of the housing, also extend away from the longitudinal direction and then again towards the longitudinal direction.
  • the long sides in the area of the second control panel thus have a convex shape when viewed from the outside, just as the sections of the long sides in the area of the first control panel have a convex shape.
  • a radius of curvature of the convex shape in the area of the second control panel is preferably greater than a radius of curvature of the convex shape in the area of the first control panel.
  • the ergonomic properties of the control switch according to the invention are further optimized by these convex or round and, in particular, curved profiles of the long sides, seen from the outside.
  • a rear side of the housing of the control switch opposite the front side has a profiled contour in the area of the first control panel and / or in the area of the third control panel.
  • the profiled contour can particularly advantageously have at least one projection which is raised compared to the rear.
  • the projection which preferably extends perpendicular to the longitudinal direction of the control switch, is provided so that a person operating the control switch can place the index finder of one of his hands on it at least in sections. In this way, an ergonomically advantageous position of the control switch in the hand can be brought about, in which the thumb of the respective hand can comfortably reach the respective, in particular the first or third, control panel and actuate the operating elements there.
  • the control switch can also be supported in an advantageous manner in particular on a section of the middle finger in the encompassed state. Without the correspondingly profiled contour or Otherwise, the operator would have to apply an increased holding force in order to prevent the control switch from sliding through the hand, which would also impair the accessibility of the respective control panel.
  • the first control panel and the third control panel are arranged together in a recess that recesses relative to the front of the housing.
  • the arrangement of the first and third control panel in this recess has the advantage that the control elements contained do not protrude beyond the contour of the control switch or the front of its housing, as a result of which sticking to the control elements and any associated incorrect operation can be effectively avoided.
  • the arrangement of the two control panels together in a recess also has the effect of advantageously enhancing their visual and / or haptic emphasis.
  • the housing has a constriction on its long sides.
  • the constriction is arranged in a particularly advantageous manner between the biconvex curves.
  • the constriction can be located in particular in the area between the first and second control panel or in the area of the first control panel and preferably at the level of an operating element of the first control panel provided for the "crane travel forward" function.
  • the constriction is then located between the two convex profiles seen from the outside in the area between the first and second control panels or in the area of the first control panel and in particular in the area of the control element for the "forward crane travel" function.
  • the first convex course of the long sides of the housing in the area of the first control panel seen from the outside therefore changes directly into the second convex course of the long sides of the housing in the area of the second control panel seen from the outside.
  • the two biconvex curves to each other in the region of the constriction preferably without a possible concave curve, merge directly and in this respect in particular in a kink-like manner.
  • the constriction thus resembles a striking notch, which leads to an advantageous enhancement of the visual and / or haptic highlighting of the individual control panels.
  • the housing has a first section, which can preferably include the third and at least partially also the first control panel, and a second section which adjoins the first section in the longitudinal direction and preferably the second Control panel can include.
  • the first section and the second section are angled so that they enclose an angle between them.
  • the two sections of the housing are angled around an imaginary axis running parallel to the transverse axis, so that its front side, preferably also its rear side, is curved in itself.
  • the first section of the housing opposite the upper end is always inclined with respect to a vertical direction even in the free-hanging state, which simplifies gripping the control switch.
  • control switch or its housing can be provided with a soft coating at least in some areas.
  • the coating serving as a soft coating is preferably produced by applying a multi-component lacquer to the housing.
  • the primary goal here is improved contact with the hand of a person operating the control switch, which hand encompasses the housing.
  • the at least one projection can be rounded off towards the long sides.
  • the rounding enables a transition from the projection into the long sides of the housing that is as seamless as possible, which further increases the ergonomics due to the absence of otherwise disruptive and / or unpleasant protruding corners of the projection.
  • the rounded design of the at least one projection also allows the control switch to be placed in a section of a finger, in particular the index finger, with the rounded projection.
  • the housing is naturally enlarged compared to the surrounding sections, which can be perceived as advantageous, in particular in the case of a large hand of a person operating the control switch. Even with this type of handling, the at least one protrusion provides exact haptic feedback regarding the correct position within the operator's hand.
  • the projections also serve to transmit tensile forces from the operator to the crane, which can be initiated via the control switch and the control line. In addition, the projections allow the operator to "hold" on the control switch and thereby carry the crane with him.
  • the housing can have two projections spaced apart from one another with respect to its longitudinal direction.
  • a first projection can be arranged at the level of an area that faces the third control panel and is located below two control elements of the first control panel that are arranged alongside one another along the transverse axis, while a second projection at the level of a lower area of the third that faces away from the first control panel Control panel is located.
  • the distance between the two projections can be selected such that the section of the housing located between the two projections is gripped by the ring and middle fingers of one hand, while the index finger is placed above the first projection.

Description

Die Erfindung betrifft einen Steuerschalter zur Bedienung eines Krans gemäß dem Oberbegriff von Anspruch 1.The invention relates to a control switch for operating a crane according to the preamble of claim 1.

Ein derartiger Steuerschalter ist aus dem Prospekt "CLX CHAIN HOIST - CRANE FOR EVERYDAY LIFTING" der Firma Konecranes bekannt. Dieser Steuerschalter ist als kabelgebundener Hängesteuerschalter ausgebildet und umfasst ein sich in seine Längsrichtung erstreckendes längliches Gehäuse. An einer Vorderseite des Gehäuses sind mehrere Bedienelemente angeordnet, um diverse Funktionen eines mit dem Steuerschalter verbindbaren Krans anzusteuern. Hierbei sind vier in Form von Tasten ausgebildete, für die Kran- und Katzfahrt vorgesehene Bedienelemente in einer kreuzförmigen Anordnung zu einem im Wesentlichen rautenförmigen ersten Bedienfeld zusammengefasst. In Längsrichtung unterhalb dieser kreuzförmigen Anordnung befindet sich ein zweites Bedienfeld mit zwei weiteren tastenförmigen Bedienelementen, die zur Ansteuerung eines Hubwerks zum Heben und Senken einer Last vorgesehen sind. Die Bedienelemente für das Hubwerk sind in Längsrichtung des Gehäuses hintereinander und insofern vertikal übereinander angeordnet. In Längsrichtung des Gehäuses oberhalb des ersten Bedienfelds ist ein drittes Bedienfeld vorgesehen, über dem eine Not Halt Taste mit senkrecht zur Vorderseite ausgerichteter Betätigungsrichtung angeordnet ist. Mit Blick auf die Vorderseite des Gehäuses ist dessen im Bereich des zweiten Bedienfelds gelegener erster Abschnitt gegenüber dem sich daran anschließenden und das erste Bedienfeld umfassenden zweiten Abschnitt schmaler ausgestaltet. Die sich gegenüberliegenden und die Vorderseite begrenzenden Längsseiten des Gehäuses weisen im Bereich des ersten Bedienfelds teilweise und im Bereich des zweiten und dritten Bedienfelds nebst Not Halt Taste einen parallelen Verlauf zueinander auf, wobei deren ansonsten durchgehend gleichbleibender Abstand lediglich im Bereich des zweiten Bedienfelds und im Bereich zwischen dem ersten und dem zweiten Bedienfeld verringert ist. Mit anderen Worten springen die Längsseiten des Gehäuses im Bereich des zweiten Bedienfelds gegenüber deren Verlauf im Bereich des ersten und dritten Bedienfelds sowie der Not Halt Taste gleichermaßen zurück und insofern aufeinander zu, wobei die Übergänge der Längsseiten zwischen dem ersten und zweiten Bedienfeld einen jeweils schrägen Verlauf aufweisen.Such a control switch is known from the brochure "CLX CHAIN HOIST - CRANE FOR EVERYDAY LIFTING" from Konecranes. This control switch is designed as a wired pendant control switch and comprises an elongated housing extending in its longitudinal direction. Several operating elements are arranged on a front side of the housing in order to control various functions of a crane which can be connected to the control switch. In this case, four control elements designed in the form of buttons and intended for crane and trolley travel are combined in a cruciform arrangement to form a substantially diamond-shaped first control panel. In the longitudinal direction below this cruciform arrangement there is a second control panel with two further button-shaped control elements, which are provided to control a lifting mechanism for lifting and lowering a load. The controls for the hoist are arranged one behind the other in the longitudinal direction of the housing and in this respect vertically one above the other. In the longitudinal direction of the housing above the first control panel, a third control panel is provided, above which an emergency stop button with an actuation direction oriented perpendicular to the front is arranged. With a view of the front of the housing, its first section located in the area of the second control panel is narrower than the second section adjoining it and comprising the first control panel. The opposite longitudinal sides of the housing, which delimit the front, have a parallel course to one another in the area of the first control panel and, in the area of the second and third control panel, in addition to the emergency stop button, their otherwise constant distance only in the area of the second control panel and in the area between the first and the second control panel is reduced. In other words, the long sides of the housing in the area of the second control panel jump back relative to their course in the area of the first and third control panel and the emergency stop button and in this respect towards one another, the transitions of the long sides between the first and second control panel each having an oblique course exhibit.

Aus der DE 10 2006 012 471 A1 ist ein weiterer Steuerschalter zur Bedienung eines Krans bekannt, dessen an seinem Gehäuse angeordnete Bedienelemente jeweils paarweise nebeneinander und in Bezug auf die Längsrichtung des Gehäuses zeilenförmig untereinander angeordnet sind.From the DE 10 2006 012 471 A1 Another control switch for operating a crane is known, the control elements arranged on its housing are arranged in pairs next to one another and in a row with one another with respect to the longitudinal direction of the housing.

Weitere Steuerschalter sind aus der DE000D0000031MAZ, dem Dokument "Technische Daten, Projektierungshandbuch, Zubehör - Demag Kettenzug DC" der Demag Cranes & Components GmbH, der EP 0 592 795 A1 und der US 4 209 681 bekannt.Further control switches are from DE000D0000031MAZ, the document "Technical data, project planning manual, accessories - Demag chain hoist DC" from Demag Cranes & Components GmbH, the EP 0 592 795 A1 and the US 4,209,681 known.

Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Steuerschalter dahingehend weiterzuentwickeln, dass dieser verbesserte ergonomische Eigenschaften für eine besonders komfortable und sichere Kranbedienung aufweist.The object of the invention is to further develop a generic control switch such that it has improved ergonomic properties for particularly comfortable and safe crane operation.

Diese Aufgabe wird durch einen Steuerschalter mit den Merkmalen des Anspruchs 1 gelöst. In den abhängigen Ansprüchen 2 bis 11 und der nachfolgenden Beschreibung sind vorteilhafte Ausgestaltungen der Erfindung angegeben.This object is achieved by a control switch with the features of claim 1. In the dependent claims 2 to 11 and the following description, advantageous embodiments of the invention are given.

Erfindungsgemäß lässt sich ein Steuerschalter zur Bedienung eines Krans, der ein sich in eine Längsrichtung erstreckendes Gehäuse umfasst, an dessen durch zwei Längsseiten begrenzten Vorderseite ein erstes Bedienfeld mit mindestens einem Bedienelement angeordnet ist, insbesondere zur Ansteuerung mindestens eines Antriebs für horizontale Kranbewegungen, wobei an der Vorderseite des Gehäuses ein zweites Bedienfeld mit einer Not-Halt-Taste und ein drittes Bedienfeld mit zwei Bedienelementen, insbesondere zur Ansteuerung vertikaler Kranbewegungen, angeordnet sind, hinsichtlich seiner ergonomischen Eigenschaften für eine besonders komfortable und sichere Kranbedienung dadurch verbessern, dass die Längsseiten im Bereich des ersten Bedienfelds einen in Längsrichtung des Gehäuses bikonvex zueinander gekrümmten und somit insbesondere nach außen gewölbten Verlauf aufweisen. Mit anderen Worten erstrecken sich die entsprechend bikonvex gewölbten Längsseiten im Bereich des ersten Bedienfeldes in Längsrichtung des Gehäuses gesehen jeweils von der Längsrichtung weg und anschließend wieder zur Längsrichtung hin.According to the invention, a control switch for operating a crane, which comprises a housing extending in a longitudinal direction, on the front side delimited by two longitudinal sides of which a first control panel with at least one control element is arranged, in particular for controlling at least one drive for horizontal crane movements, whereby on the Front of the housing, a second control panel with an emergency stop button and a third control panel with two controls, in particular for controlling vertical crane movements, are arranged, in terms of its ergonomic properties for a particularly comfortable and safe crane operation by improving that the long sides in the area of the first control panel have a curve that is biconvex to one another in the longitudinal direction of the housing and thus, in particular, curved outward. In other words, the correspondingly biconvex curved longitudinal sides in the area of the first control panel, viewed in the longitudinal direction of the housing, extend away from the longitudinal direction and then again towards the longitudinal direction.

Das erste Bedienfeld kann insbesondere rautenförmig sein. In einer bevorzugten Ausführungsform umfasst das erste Bedienfeld mindestens zwei Bedienelemente, die entlang einer parallel zur Längsrichtung des Gehäuses verlaufenden Längsachse des ersten Bedienfelds übereinander und/oder entlang einer quer zur Längsrichtung des Gehäuses verlaufenden Querachse des ersten Bedienfelds nebeneinander angeordnet sind.The first control panel can be diamond-shaped in particular. In a preferred one Embodiment, the first control panel comprises at least two control elements which are arranged one above the other along a longitudinal axis of the first control panel running parallel to the longitudinal direction of the housing and / or alongside one another along a transverse axis of the first control panel running transverse to the longitudinal direction of the housing.

Ein Scheitelpunkt von jedem dieser - von außen gesehen konvex verlaufenden und insofern bikonvex zueinander - gekrümmten, insbesondere rundlichen, Abschnitte der Längsseiten befindet sich jeweils auf Höhe des mindestens einen Bedienelements beziehungsweise auf Höhe der entlang der Querachse nebeneinander angeordneten Bedienelemente und/oder auf Höhe der zwischen den entlang der Längsachse übereinander angeordneten Bedienelementen verlaufenden Querachse. Mit Bezug auf die rautenförmige Ausgestaltung befinden sich die Scheitelpunkte folglich auf Höhe der sich in Querrichtung des Gehäuses gegenüberliegenden Ecken des rautenförmigen ersten Bedienfelds. Ein Vorteil dieser Ausgestaltung ist, dass das erste Bedienfeld sowohl optisch als auch haptisch stärker hervorgehoben wird und dadurch insbesondere ein sicheres Greifen und Halten des Steuerschalters ermöglicht ist. Aufgrund der leicht tastbaren und somit auch ohne visuelle Wahrnehmung erfassbaren Ausgestaltung des Steuerschalters ist eine überaus schnelle und intuitive Orientierung hinsichtlich dessen Bedienung ermöglicht. Auch lässt sich das erste Bedienfeld besonders gut von dem Daumen der den Steuerschalter im Bereich unterhalb des bikonvexen Verlaufs der Längsseiten haltenden Hand einer diesen bedienenden Person erreichen.A vertex of each of these - from the outside, convex and in this respect biconvex to each other - curved, in particular rounded, sections of the long sides is located at the level of the at least one control element or at the level of the control elements arranged alongside one another along the transverse axis and / or at the level of the between the transverse axis extending along the longitudinal axis of the control elements. With regard to the diamond-shaped configuration, the apexes are consequently at the level of the corners of the diamond-shaped first control panel opposite one another in the transverse direction of the housing. An advantage of this configuration is that the first control panel is emphasized both optically and haptically, and in particular this enables the control switch to be gripped and held securely. Due to the easily palpable design of the control switch, which can thus also be detected without visual perception, an extremely fast and intuitive orientation with regard to its operation is made possible. The first control panel can also be reached particularly well by the thumb of the hand of a person operating the control switch in the area below the biconvex course of the long sides.

Das erste Bedienfeld ist insbesondere derart ausgebildet, dass innerhalb des Bedienfelds bis zu vier Bedienelemente für horizontale Kranbewegungen beziehungsweise zur Ansteuerung des mindestens einen Antriebs für die horizontalen Kranbewegungen, insbesondere eine Kranfahrt und/oder Katzfahrt des Krans, kreuzförmig auf dem, insbesondere rautenförmigen, ersten Bedienfeld angeordnet sein können. Mit der kreuzförmigen Anordnung ist gemeint, dass jedes Bedienelement des ersten Bedienfelds - wie anhand der Figuren noch näher beschrieben wird - in jeweils einer Ecke einer gedachten Raute des insbesondere rautenförmigen ersten Bedienfelds angeordnet ist, wobei die sich kreuzenden Diagonalen dieser Raute der Längsachse und Querachse des ersten Bedienfelds entsprechen, von denen die Längsachse parallel und die Querachse entsprechend quer zur Längsrichtung des Steuerschalters beziehungsweise dessen Gehäuse ausgerichtet sind. Wenn das erste Bedienfeld nur ein Bedienelement für horizontale Kranbewegungen beziehungsweise zur Ansteuerung der Kranfahrt und/oder Katzfahrt beziehungsweise zugehöriger Antriebe aufweist, kann das somit insbesondere multifunktionale Bedienelement auch mittig zwischen den Längsseiten und insbesondere auf einem Kreuzungspunkt der Diagonalen der gedachten Raute angeordnet sein. In diesem Fall sind dann jedoch in den Ecken der gedachten Raute keine Bedienelemente angeordnet.The first control panel is designed in particular in such a way that up to four control elements for horizontal crane movements or for controlling the at least one drive for the horizontal crane movements, in particular a crane travel and / or trolley travel of the crane, cross-shaped on the, in particular diamond-shaped, first control panel within the control panel can be arranged. The cross-shaped arrangement means that each control element of the first control panel - as will be described in more detail with reference to the figures - is arranged in a corner of an imaginary rhombus of the diamond-shaped first control panel, the intersecting diagonals of this rhombus of the longitudinal axis and transverse axis of the correspond to the first control panel, of which the longitudinal axis is parallel and the transverse axis is corresponding are aligned transversely to the longitudinal direction of the control switch or its housing. If the first control panel has only one control element for horizontal crane movements or for controlling the crane travel and / or trolley travel or associated drives, the multifunctional control element in particular can thus also be arranged centrally between the long sides and in particular on an intersection of the diagonals of the imaginary diamond. In this case, however, no control elements are arranged in the corners of the imaginary diamond.

Der Steuerschalter beziehungsweise sein Gehäuse weist einschließlich der Verläufe der Längsseiten, der Anordnung der Bedienfelder sowie der zugehörigen Bedienelemente eine spiegelsymmetrische Form in Bezug auf eine gedachte Ebene auf, die senkrecht auf der Vorderseite steht und die Längsachsrichtung des Steuerschalters beziehungsweise seines Gehäuses beinhaltet. Aufgrund der Spiegelsymmetrie kann der Steuerschalter von Linkshändern und Rechtshändern in gleicher Weise komfortabel und sicher gegriffen und gehalten werden.The control switch or its housing, including the courses of the long sides, the arrangement of the control panels and the associated control elements, has a mirror-symmetrical shape with respect to an imaginary plane that is perpendicular to the front and contains the longitudinal axis direction of the control switch or its housing. Due to the mirror symmetry, the control switch can be gripped and held comfortably and securely by left-handed and right-handed people in the same way.

In vorteilhafter Weise sind an der Vorderseite des Gehäuses zwischen den Längsseiten zusätzlich zu dem ersten Bedienfeld ein zweites Bedienfeld mit einer Not-Halt-Taste sowie ein drittes Bedienfeld mit zwei Bedienelementen vorgesehen. Die Bedienelemente des dritten Bedienfelds können bevorzugt zur Ansteuerung eines Antriebs für vertikale Kranbewegungen, insbesondere eines Hubwerks, eines mit dem Steuerschalter verbindbaren Krans dienen. Bevorzugt ist das erste Bedienfeld - in Bezug auf die Längsrichtung des Gehäuses - zwischen dem zweiten Bedienfeld und dem dritten Bedienfeld angeordnet.Advantageously, in addition to the first control panel, a second control panel with an emergency stop button and a third control panel with two control elements are provided on the front of the housing between the long sides. The control elements of the third control panel can preferably be used to control a drive for vertical crane movements, in particular a hoist, of a crane that can be connected to the control switch. In relation to the longitudinal direction of the housing, the first control panel is preferably arranged between the second control panel and the third control panel.

Das dritte Bedienelement umfasst vorzugsweise zwei Bedienelemente für ein Hubwerk des Krans, die in Bezug auf die Längsrichtung des Steuerschalters beziehungsweise dessen Gehäuse hintereinander angeordnet sind. Durch diese Ausgestaltung wird eine besonders ergonomische und zugleich auch eine besonders intuitive Bedienung eines Krans möglich, wodurch die Sicherheit im Kranbetrieb weiter gesteigert werden kann. Die Bedienelemente aller Bedienfelder sind vorzugsweise als Tasten, insbesondere als Drucktasten, ausgebildet.The third control element preferably comprises two control elements for a lifting mechanism of the crane, which are arranged one behind the other in relation to the longitudinal direction of the control switch or its housing. This configuration makes it possible to operate a crane in a particularly ergonomic and at the same time particularly intuitive manner, as a result of which safety in crane operation can be further increased. The control elements of all control panels are preferably designed as buttons, in particular as push buttons.

Eine vorteilhafte Ausgestaltung sieht vor, dass die Längsseiten des Gehäuses auch im Bereich des zweiten Bedienfeldes einen in Längsrichtung des Gehäuses bikonvex zueinander gekrümmten Verlauf aufweisen. Mit anderen Worten erstrecken sich auch die Längsseiten im Bereich des zweiten Bedienfeldes in Längsrichtung des Gehäuses gesehen jeweils von der Längsrichtung weg und anschließend wieder zur Längsrichtung hin. Die Längsseiten im Bereich des zweiten Bedienfeldes weisen somit einen von außen gesehen ebenso konvexen Verlauf auf, wie auch die Abschnitte der Längsseiten im Bereich des ersten Bedienfeldes einen konvexen Verlauf aufweisen. Die in Bezug auf das erste Bedienfeld genannten Vorteile eines solchen Verlaufs gelten hier entsprechend. Ein Krümmungsradius des konvexen Verlaufs im Bereich des zweiten Bedienfeldes ist dabei bevorzugt größer als ein Krümmungsradius des konvexen Verlaufs im Bereich des ersten Bedienfeldes. Durch diese von außen gesehen abschnittsweisen konvexen beziehungsweise runden und insbesondere gewölbten Verläufe der Längsseiten werden die ergonomischen Eigenschaften des erfindungsgemäßen Steuerschalters weiter optimiert.An advantageous embodiment provides that the long sides of the housing also have a biconvex curve in the longitudinal direction of the housing in the area of the second control panel. In other words, the longitudinal sides in the region of the second control panel, viewed in the longitudinal direction of the housing, also extend away from the longitudinal direction and then again towards the longitudinal direction. The long sides in the area of the second control panel thus have a convex shape when viewed from the outside, just as the sections of the long sides in the area of the first control panel have a convex shape. The advantages of such a course mentioned in relation to the first control panel apply here accordingly. A radius of curvature of the convex shape in the area of the second control panel is preferably greater than a radius of curvature of the convex shape in the area of the first control panel. The ergonomic properties of the control switch according to the invention are further optimized by these convex or round and, in particular, curved profiles of the long sides, seen from the outside.

In vorteilhafter Weise kann zudem vorgesehen sein, dass eine der Vorderseite gegenüberliegende Rückseite des Gehäuses des Steuerschalters im Bereich des ersten Bedienfeldes und/oder im Bereich des dritten Bedienfeldes eine profilierte Kontur aufweist. Besonders vorteilhaft kann die profilierte Kontur wenigstens einen gegenüber der Rückseite erhöhten Vorsprung aufweisen. Der sich bevorzugt senkrecht zur Längsrichtung des Steuerschalters erstreckende Vorsprung ist dazu vorgesehen, dass eine den Steuerschalter bedienende Person den Zeigefinder einer ihrer Hände zumindest abschnittsweise auf diesen auflegen kann. Auf diese Weise kann eine ergonomisch vorteilhafte Zwangslage des Steuerschalters in der Hand herbeigeführt werden, in der der Daumen der jeweiligen Hand bequem das jeweilige, insbesondere das erste beziehungsweise dritte, Bedienfeld erreichen und die dortigen Bedienelemente betätigen kann. Wenn zwei derartige Vorsprünge vorgesehen sind, sind diese in Längsrichtung des Gehäuses so voneinander beabstandet, dass ein erster Vorsprung die entsprechende Zwangslage zur Erreichbarkeit des ersten Bedienfelds durch den Daumen ermöglicht und ein zweiter Vorsprung die entsprechende Zwangslage zur Erreichbarkeit des dritten Bedienfelds durch den Daumen ermöglicht. Da sich die restlichen Finger dabei gleichzeitig unterhalb des jeweiligen wenigstens einen Vorsprungs befinden, kann sich der Steuerschalter im umgriffenen Zustand zudem in vorteilhafter Weise insbesondere auf einem Abschnitt des Mittelfingers abstützen. Ohne die entsprechend profilierte Kontur bzw. den jeweiligen Vorsprung wäre von der Bedienperson ansonsten eine erhöhte Haltekraft aufzubringen, um zu verhindern, dass der Steuerschalter durch die Hand gleitet, wodurch sich auch die Erreichbarkeit des jeweiligen Bedienfelds verschlechtern würde.It can also be advantageously provided that a rear side of the housing of the control switch opposite the front side has a profiled contour in the area of the first control panel and / or in the area of the third control panel. The profiled contour can particularly advantageously have at least one projection which is raised compared to the rear. The projection, which preferably extends perpendicular to the longitudinal direction of the control switch, is provided so that a person operating the control switch can place the index finder of one of his hands on it at least in sections. In this way, an ergonomically advantageous position of the control switch in the hand can be brought about, in which the thumb of the respective hand can comfortably reach the respective, in particular the first or third, control panel and actuate the operating elements there. If two such projections are provided, they are spaced apart from one another in the longitudinal direction of the housing such that a first projection enables the corresponding constraint position to be reached by the thumb and the second control projection enables the corresponding constraint position to be reached by the thumb. Since the remaining fingers are at the same time below the respective at least one projection, the control switch can also be supported in an advantageous manner in particular on a section of the middle finger in the encompassed state. Without the correspondingly profiled contour or Otherwise, the operator would have to apply an increased holding force in order to prevent the control switch from sliding through the hand, which would also impair the accessibility of the respective control panel.

In vorteilhafter Weise ist zudem vorgesehen, dass das erste Bedienfeld und das dritte Bedienfeld gemeinsam in einer gegenüber der Vorderseite des Gehäuses zurückspringenden Vertiefung angeordnet sind. Die Anordnung des ersten und dritten Bedienfeldes in dieser Vertiefung hat den Vorteil, dass die enthaltenen Bedienelemente nicht über die Kontur des Steuerschalters beziehungsweise die Vorderseite dessen Gehäuses hinausragen, wodurch ein Hängenbleiben an den Bedienelementen und eine damit eventuell einhergehende Fehlbedienung wirksam vermieden werden kann. Die Anordnung beider Bedienfelder gemeinsam in einer Vertiefung hat zudem den Effekt, dass hierdurch deren optische und/oder haptische Hervorhebung vorteilhaft verstärkt wird.In an advantageous manner, it is also provided that the first control panel and the third control panel are arranged together in a recess that recesses relative to the front of the housing. The arrangement of the first and third control panel in this recess has the advantage that the control elements contained do not protrude beyond the contour of the control switch or the front of its housing, as a result of which sticking to the control elements and any associated incorrect operation can be effectively avoided. The arrangement of the two control panels together in a recess also has the effect of advantageously enhancing their visual and / or haptic emphasis.

In einer weiteren vorteilhaften Ausgestaltung weist das Gehäuse eine Einschnürung seiner Längsseiten auf. In besonders vorteilhafter Weise ist die Einschnürung zwischen den bikonvex zueinander gekrümmten Verläufen angeordnet. In dieser Ausgestaltung kann sich die Einschnürung insbesondere im Bereich zwischen dem ersten und zweiten Bedienfeld oder im Bereich des ersten Bedienfelds und vorzugsweise in Höhe eines für die Funktion "Kranfahrt vorwärts" vorgesehenen Bedienelements des ersten Bedienfelds befinden. Mit anderen Worten ist die Einschnürung dann zwischen den beiden von außen gesehen konvexen Verläufen im Bereich zwischen dem ersten und zweiten Bedienfeld oder im Bereich des ersten Bedienfelds und insbesondere im Bereich des Bedienelementes für die Funktion "Kranfahrt vorwärts" gelegen. Der erste von außen gesehen konvexe Verlauf der Längsseiten des Gehäuses im Bereich des ersten Bedienfeldes geht demnach direkt in den zweiten von außen gesehen konvexen Verlauf der Längsseiten des Gehäuses im Bereich des zweiten Bedienfeldes über. Vorteilhaft können die beiden bikonvex zueinander gekrümmten Verläufe im Bereich der Einschnürung unter Verzicht auf einen möglichen konkaven Verlauf bevorzugt unmittelbar und insofern insbesondere knickförmig ineinander übergehen. Die Einschnürung gleicht somit einer markanten Kerbe, welche zu einer vorteilhaften Verstärkung der optischen und/oder haptischen Hervorhebung der einzelnen Bedienfelder führt.In a further advantageous embodiment, the housing has a constriction on its long sides. The constriction is arranged in a particularly advantageous manner between the biconvex curves. In this embodiment, the constriction can be located in particular in the area between the first and second control panel or in the area of the first control panel and preferably at the level of an operating element of the first control panel provided for the "crane travel forward" function. In other words, the constriction is then located between the two convex profiles seen from the outside in the area between the first and second control panels or in the area of the first control panel and in particular in the area of the control element for the "forward crane travel" function. The first convex course of the long sides of the housing in the area of the first control panel seen from the outside therefore changes directly into the second convex course of the long sides of the housing in the area of the second control panel seen from the outside. Advantageously, the two biconvex curves to each other in the region of the constriction, preferably without a possible concave curve, merge directly and in this respect in particular in a kink-like manner. The constriction thus resembles a striking notch, which leads to an advantageous enhancement of the visual and / or haptic highlighting of the individual control panels.

Die ergonomischen Eigenschaften des Steuerschalters werden insbesondere weiter dadurch verbessert, dass das Gehäuse einen ersten Abschnitt, welcher bevorzugt das dritte und zumindest teilweise auch das erste Bedienfeld umfassen kann, und einen sich in Längsrichtung an den ersten Abschnitt anschließenden zweiten Abschnitt besitzt, der bevorzugt das zweite Bedienfeld umfassen kann. Der erste Abschnitt und der zweite Abschnitt sind dabei so zueinander abgewinkelt, dass diese einen Winkel zwischen sich einschließen. Die Abwinkelung der beiden Abschnitte des Gehäuses erfolgt dabei um eine parallel zur Querachse verlaufende gedachte Achse herum, so dass dessen Vorderseite, bevorzugt auch dessen Rückseite, in sich gekrümmt ist. Insbesondere mit Blick auf die Ausgestaltung als Hängesteuerschalter in Kombination mit einer am oberen Ende des Gehäuses angeordneten Steuerleitung ist so der dem oberen Ende gegenüberliegende erste Abschnitt des Gehäuses auch im freihängenden Zustand stets gegenüber einer Vertikalrichtung geneigt, wodurch das Ergreifen des Steuerschalters vereinfacht ist.The ergonomic properties of the control switch are further improved, in particular, in that the housing has a first section, which can preferably include the third and at least partially also the first control panel, and a second section which adjoins the first section in the longitudinal direction and preferably the second Control panel can include. The first section and the second section are angled so that they enclose an angle between them. The two sections of the housing are angled around an imaginary axis running parallel to the transverse axis, so that its front side, preferably also its rear side, is curved in itself. Particularly with a view to the design as a pendant control switch in combination with a control line arranged at the upper end of the housing, the first section of the housing opposite the upper end is always inclined with respect to a vertical direction even in the free-hanging state, which simplifies gripping the control switch.

In vorteilhafter Weise ist zudem vorgesehen, dass der Steuerschalter beziehungsweise dessen Gehäuse zumindest bereichsweise mit einem Soft-Coating versehen sein kann. Vorzugsweise wird die als Soft-Coating dienende Beschichtung durch Aufbringen eines Mehrkomponenten-Lacks auf das Gehäuse hergestellt. Ziel hierbei ist primär ein verbesserter Kontakt zu der das Gehäuse umgreifenden Hand einer den Steuerschalter bedienenden Person. Hinzu kommt ein in Bezug auf Wertigkeit und/oder Komfort gesteigertes haptisches Erlebnis im Umgang mit dem Steuerschalter.It is also advantageously provided that the control switch or its housing can be provided with a soft coating at least in some areas. The coating serving as a soft coating is preferably produced by applying a multi-component lacquer to the housing. The primary goal here is improved contact with the hand of a person operating the control switch, which hand encompasses the housing. In addition, there is an increased haptic experience when using the control switch in terms of value and / or comfort.

Gemäß einer bevorzugten Weiterbildung in Bezug auf die Möglichkeit zur Anordnung einer profilierten Kontur an der Rückseite des Gehäuses kann der wenigstens eine Vorsprung zu den Längsseiten hin abgerundet sein. Die Abrundung ermöglicht einen möglichst nahtlosen Übergang des Vorsprungs in die Längsseiten des Gehäuses, was die Ergonomie aufgrund des Fehlens ansonsten störender und/oder unangenehmer abstehender Ecken des Vorsprungs weiter erhöht. Je nach Bedienerverhalten lässt die so abgerundete Ausgestaltung des wenigstens einen Vorsprungs auch die Möglichkeit zu, den Steuerschalter quasi mit dem so abgerundeten Vorsprung in einem Abschnitt eines Fingers, insbesondere des Zeigefinders, abzulegen. Der in der Ebene des Vorsprungs gelegene Querschnitt des Gehäuses ist aufgrund des hervortretenden Vorsprungs naturgemäß gegenüber den umliegenden Abschnitten vergrößert, was insbesondere bei einer groß gewachsenen Hand einer den Steuerschalter bedienenden Person als vorteilhaft empfunden werden kann. Auch bei einer solchen Handhabung bewirkt der wenigstens eine Vorsprung eine exakte haptische Rückmeldung in Bezug auf die korrekte Lage innerhalb der Bedienerhand. Die Vorsprünge dienen zusätzlich der Übertragung von Zugkräften des Bedieners auf den Kran, die über den Steuerschalter und die Steuerleitung eingeleitet werden können. Darüber hinaus erlauben die Vorsprünge ein "Festhalten" des Bedieners am Steuerschalter und dadurch ein Mitführen des Krans.According to a preferred development with regard to the possibility of arranging a profiled contour on the rear of the housing, the at least one projection can be rounded off towards the long sides. The rounding enables a transition from the projection into the long sides of the housing that is as seamless as possible, which further increases the ergonomics due to the absence of otherwise disruptive and / or unpleasant protruding corners of the projection. Depending on the operator behavior, the rounded design of the at least one projection also allows the control switch to be placed in a section of a finger, in particular the index finger, with the rounded projection. The cross section of the Due to the protruding protrusion, the housing is naturally enlarged compared to the surrounding sections, which can be perceived as advantageous, in particular in the case of a large hand of a person operating the control switch. Even with this type of handling, the at least one protrusion provides exact haptic feedback regarding the correct position within the operator's hand. The projections also serve to transmit tensile forces from the operator to the crane, which can be initiated via the control switch and the control line. In addition, the projections allow the operator to "hold" on the control switch and thereby carry the crane with him.

In besonders bevorzugter Weise kann das Gehäuse zwei in Bezug auf dessen Längsrichtung zueinander beabstandete Vorsprünge besitzen. Vorteilhafterweise kann dabei ein erster Vorsprung auf Höhe eines Bereichs angeordnet sein, der dem dritten Bedienfeld zugewandt ist und unterhalb zweier entlang der Querachse nebeneinander angeordneter Bedienelemente des ersten Bedienfelds gelegen ist, während ein zweiter Vorsprung auf Höhe eines von dem ersten Bedienfeld abgewandten unteren Bereichs des dritten Bedienfelds gelegen ist. Der Abstand zwischen den beiden Vorsprüngen kann so gewählt sein, dass der zwischen den beiden Vorsprüngen gelegene Abschnitt des Gehäuses mit Ring- und Mittelfinger einer Hand umgriffen wird, während der Zeigefinger oberhalb des ersten Vorsprungs abgelegt ist. Der erste Vorsprung dient dem Bediener als Orientierungshilfe zur Bedienung des ersten Bedienfelds, während der zweite Vorsprung eine Orientierungshilfe für das dritte Bedienfeld darstellt.In a particularly preferred manner, the housing can have two projections spaced apart from one another with respect to its longitudinal direction. Advantageously, a first projection can be arranged at the level of an area that faces the third control panel and is located below two control elements of the first control panel that are arranged alongside one another along the transverse axis, while a second projection at the level of a lower area of the third that faces away from the first control panel Control panel is located. The distance between the two projections can be selected such that the section of the housing located between the two projections is gripped by the ring and middle fingers of one hand, while the index finger is placed above the first projection. The first projection serves as an orientation aid for the operator to operate the first control panel, while the second projection represents an orientation aid for the third control panel.

Two exemplary embodiments of the invention are explained in more detail with reference to the following description. Show it:
  • Figure 1 2 shows a perspective view of the front and one long side of a control switch,
  • Figure 2 a perspective view of the back and the long side of the control switch Figure 1 ,

Die Figur 1 zeigt eine perspektivische Ansicht der Vorderseite 2a sowie einer Längsseite 2d eines erfindungsgemäßen Steuerschalters 1 zur Bedienung eines Krans. Der hier nicht näher gezeigte Kran kann insbesondere ein Laufkran sein, beispielsweise in Form eines Brückenkrans. Der Steuerschalter 1 ist erkennbar als Handsteuerschalter in Form eines Hängesteuerschalters ausgebildet und umfasst hierfür ein sich in seine Längsrichtung L erstreckendes längliches Gehäuse 2. Die üblicherweise mit dem Steuerschalter an seinem mit Bezug auf die Darstellung von Figur 1 oberen Ende angeordnete oder anordenbare Steuerleitung zur Verbindung mit einem Kran ist vorliegend nicht ersichtlich. Das Gehäuse 2 ist längsseitig, das heißt an seinen gegenüberliegenden Längsseiten 2c, 2d, profiliert, insbesondere durch einen ersten von außen gesehen konvexen Verlauf 13a der Längsseiten 2c, 2d, der sich im Bereich eines an der Vorderseite 2a angeordneten ersten Bedienfelds 3 mit Bezug auf die Längsrichtung L des Steuerschalters 1 jeweils von der Längsrichtung L weg und anschließend wieder zur Längsrichtung L hin erstreckt. Auf diese Weise weisen die beiden sich gegenüberliegenden Längsseiten 2c, 2d einen bikonvex zueinander gekrümmten Verlauf 13a auf. Zusätzlich weist der Steuerschalter 1, beziehungsweise weisen die Längsseiten 2c, 2d von dessen Gehäuse 2, einen zweiten von außen gesehen konvexen Verlauf 13b im Bereich eines ebenfalls auf der Vorderseite 2a angeordneten zweiten Bedienfelds 4 auf. Damit sind beide sich gegenüberliegenden Längsseiten 2c, 2d in diesem Bereich ebenfalls mit einem bikonvex zueinander gekrümmten Verlauf 13b ausgestattet. Erkennbar sind die beiden von außen gesehen konvexen Verläufe 13a, 13b durch eine Einschnürung 11 voneinander getrennt. Weiterhin weist das Gehäuse 2 des Steuerschalters 1 an seiner Vorderseite 2a ein weiteres drittes Bedienfeld 5 auf, wobei das erste Bedienfeld 3 zwischen dem zweiten Bedienfeld 4 und dem dritten Bedienfeld 5 angeordnet ist.The Figure 1 shows a perspective view of the front 2a and a longitudinal side 2d of a control switch 1 according to the invention for operating a crane. The crane, not shown in more detail here, can in particular be an overhead crane, for example in the form of a gantry crane. The control switch 1 is recognizable as a manual control switch in the form of a pendant control switch and for this purpose comprises an elongated housing 2 extending in its longitudinal direction L, which is usually associated with the control switch at its with reference to the illustration of FIG Figure 1 Control line arranged or can be arranged at the upper end for connection to a crane cannot be seen here. The housing 2 is profiled on the long side, that is to say on its opposite long sides 2c, 2d, in particular by a first, from the outside, a convex course 13a of the long sides 2c, 2d, which is located in the region of a first control panel 3 arranged on the front 2a with reference to the longitudinal direction L of the control switch 1 extends away from the longitudinal direction L and then again towards the longitudinal direction L. In this way, the two opposite longitudinal sides 2c, 2d have a biconvex curve 13a with respect to one another. In addition, the control switch 1, or the longitudinal sides 2c, 2d of its housing 2, has a second convex course 13b, seen from the outside, in the region of a second control panel 4 likewise arranged on the front side 2a. This means that the two opposite longitudinal sides 2c, 2d in this area are also equipped with a biconvex curve 13b. The two convex courses 13a, 13b, seen from the outside, can be seen separated from one another by a constriction 11. Furthermore, the housing 2 of the control switch 1 has a further third control panel 5 on its front side 2a, the first control panel 3 being arranged between the second control panel 4 and the third control panel 5.

Mit Blick auf Figur 2 wird deutlich, dass der Steuerschalter 1 auch an seiner Rückseite 2b, beziehungsweise an der Rückseite 2b seines Gehäuses 2, eine profilierte Kontur aufweist. Durch die profilierte Kontur ist zwischen den Längsenden 2e, 2f des Steuerschalters 1, beziehungsweise seines Gehäuses 2, ein ergonomisch optimierter Greifbereich ausgebildet. In diesem Greifbereich kann der Steuerschalter 1 von der Hand einer hier nicht gezeigten und den Steuerschalter 1 bedienenden Person bequem umgriffen und gehalten werden, um an der Vorderseite 2a angeordnete Bedienelemente 3a 3d; 4a; 5a, 5b der Bedienfelder 3, 4, 5 insbesondere mit dem Daumen erreichen und betätigen zu können.With a view to Figure 2 it becomes clear that the control switch 1 also has a profiled contour on its rear side 2b, or on the rear side 2b of its housing 2. The profiled contour forms an ergonomically optimized gripping area between the longitudinal ends 2e, 2f of the control switch 1, or its housing 2. In this gripping area, the control switch 1 can be operated by the hand of a person (not shown here) who operates the control switch 1 can be comfortably gripped and held to control elements 3a 3d; 4a; 5a, 5b of the control panels 3, 4, 5 can be reached and operated, in particular with the thumb.

Durch die Betätigung der Bedienelemente 3a 3d; 4a; 5a, 5b können zahlreiche Funktionen eines Krans gesteuert werden, beispielsweise eine Kranfahrt, eine Katzfahrt sowie Heben und Senken eines Hubwerks des Krans beziehungsweise seines Lastaufnahmemittels. Während der Kranfahrt wird der Kran, insbesondere einschließlich seines Kranträgers, entlang von Kranschienen mittels Kranfahrwerken verfahren, die im Falle eines Brückenkrans an den gegenüberliegenden Enden des Kranträgers befestigt sind. Während der Katzfahrt wird eine Krankatze gemeinsam mit dem von der Krankatze getragenen Hubwerk entlang des Kranträgers mittels eines Katzfahrwerks verfahren. Üblicherweise verlaufen die Fahrtrichtungen der Kranfahrt und der Katzfahrt rechtwinklig zueinander, wobei die Kranfahrt quer, insbesondere rechtwinklig, zur Längserstreckung des Kranträgers und die Katzfahrt entlang der Längserstreckung des Kranträgers erfolgt. Die Betätigung der Bedienelemente des Steuerschalters 1 bewirkt das Erzeugen entsprechender Steuersignale für die jeweilige Funktion. Die Steuersignale werden dann an den Kran beziehungsweise dessen Steuerung gesendet, um die jeweilige Funktion auszulösen, beispielsweise durch entsprechendes Ansteuern des zugehörigen Antriebs des Kranfahrwerks, Katzfahrwerks beziehungsweise Hubwerks und dadurch bewirktes Ausführen der gewünschten Bewegung.By operating the controls 3a 3d; 4a; 5a, 5b, numerous functions of a crane can be controlled, for example a crane travel, a trolley travel as well as lifting and lowering a hoist of the crane or its load-carrying means. During the crane travel, the crane, in particular including its crane girder, is moved along crane rails by means of crane trolleys which, in the case of a bridge crane, are fastened to the opposite ends of the crane girder. During the trolley travel, a crane trolley is moved together with the hoist carried by the crane trolley along the crane girder by means of a trolley trolley. Usually, the directions of travel of the crane run and the trolley run are perpendicular to each other, the crane run transversely, in particular at right angles, to the longitudinal extension of the crane girder and the trolley travel along the longitudinal extension of the crane girder. The actuation of the control elements of the control switch 1 causes the generation of corresponding control signals for the respective function. The control signals are then sent to the crane or its control in order to trigger the respective function, for example by correspondingly controlling the associated drive of the crane trolley, trolley trolley or hoisting gear and thereby executing the desired movement.

Der Steuerschalter 1, beziehungsweise sein Gehäuse 2, weist einschließlich der Bedienfelder 3, 4, 5 und der Anordnung der Bedienelemente 3a 3d; 4a; 5a, 5b eine spiegelsymmetrische Form in Bezug auf eine Ebene auf, die senkrecht auf der Zeichenebene der Figuren 3 und 4 beziehungsweise der Vorderseite 2a steht und die Längsrichtung L des Steuerschalters 1, beziehungsweise seines Gehäuses 2, beinhaltet. Hiervon ausgenommen sind einige der den jeweiligen Bedienelementen 3a 3d; 4a; 5a, 5b zugeordneten unterschiedlichen Symbole und Beschriftungen. Aufgrund der Spiegelsymmetrie kann der Steuerschalter 1 von Linkshändern und Rechtshändern in gleicher Weise komfortabel und sicher gegriffen und gehalten werden.The control switch 1, or its housing 2, includes the control panels 3, 4, 5 and the arrangement of the control elements 3a 3d; 4a; 5a, 5b have a mirror-symmetrical shape with respect to a plane that is perpendicular to the plane of the drawing Figures 3 and 4th or the front side 2a and includes the longitudinal direction L of the control switch 1, or its housing 2. This does not apply to some of the respective control elements 3a 3d; 4a; 5a, 5b assigned different symbols and labels. Due to the mirror symmetry, the control switch 1 can be gripped and held comfortably and securely by left-handers and right-handers in the same way.

In dem Gehäuse 2 ist ausreichend Raum, um nicht dargestellte Bauteile wie eine vorzugsweise aufladbare Batterie, mechanische und elektrische Teile der Bedienelemente und eine Steuerschaltung zum Generieren, Verarbeiten und Übertragen, das heißt Senden und Empfangen, von Steuersignalen zur beziehungsweise von der Steuerung des Krans aufzunehmen. Die Steuerschaltung 1 ist hierfür über eine nicht näher gezeigte Steuerleitung mit der Steuerung des Krans verbindbar, um eine kabelgebundene Signalübertragung zu ermöglichen. Das Gehäuse 2 ist stirnseitig an seinem ersten Ende 2e mit der Steuerleitung verbindbar oder bereits verbunden. Das erste Ende 2e ist vom Körper einer Bedienperson abgewandt, während diese den Steuerschalter 1 zur Bedienung eines Krans in der Hand hält. Der Steuerschalter 1 ist also mittels der Steuerleitung und hierüber mit der Steuerung des Krans verbunden und dadurch als so genannter Hängesteuerschalter ausgebildet.There is sufficient space in the housing 2 to hold components (not shown) such as one preferably rechargeable battery, mechanical and electrical parts of the control elements and a control circuit for generating, processing and transmitting, that is to say sending and receiving, of control signals for the control of the crane. For this purpose, the control circuit 1 can be connected to the control of the crane via a control line (not shown in more detail) in order to enable a wired signal transmission. The housing 2 can be connected to the control line at its front end 2e or is already connected. The first end 2e faces away from the body of an operator while he is holding the control switch 1 for operating a crane in his hand. The control switch 1 is thus connected to the control of the crane by means of the control line and thereby and is thus designed as a so-called pendant control switch.

Ersichtlich sind die Bedienelemente 3a 3d; 4a; 5a, 5b des Steuerschalters 1 in den drei voneinander beabstandeten Bedienfeldern 3, 4, 5 gruppiert und an der in den Figuren 1 und 3 dargestellten Vorderseite 2a des Steuerschalters 1, beziehungsweise seines Gehäuses 2, in der nachfolgend erläuterten Weise ergonomisch besonders vorteilhaft angeordnet:
Die drei Bedienfelder 3, 4, 5 sind entlang der Längsrichtung L des Steuerschalters 1 beziehungsweise des Gehäuses 2 zwischen dessen beiden Längsenden, dem oberen ersten Ende 2e und einem gegenüberliegenden unteren zweiten Ende 2f, nebeneinander und mit Bezug auf die übliche Handhabung des Steuerschalters 1 insofern übereinander positioniert. Das im Bereich des ersten Endes 2e des Gehäuses 2 vorgesehene zweite Bedienfeld 4 umfasst ein Bedienelement in Form einer Drucktaste, welche eine Not-Halt-Taste 4a darstellt. Das Bedienelement beziehungsweise die Not-Halt-Taste 4a ist dabei vorzugsweise in prägnant herausragender Weise angeordnet, so dass ein besonders schnelles und paniksicheres Auslösen eines Not-Halts möglich ist. Mit anderen Worten springt die Not-Halt-Taste 4a vorliegend gegenüber der Vorderseite 2a des Gehäuses 2 hervor, so dass diese schnell haptisch erfassbar und bedienbar ist (siehe auch Figuren 2 und 5).
The control elements 3a 3d are visible; 4a; 5a, 5b of the control switch 1 grouped in the three spaced apart control panels 3, 4, 5 and on the in the Figures 1 and 3rd Front side 2a of the control switch 1, or its housing 2, shown is arranged in an ergonomically particularly advantageous manner in the manner explained below:
The three control panels 3, 4, 5 are along the longitudinal direction L of the control switch 1 or the housing 2 between its two longitudinal ends, the upper first end 2e and an opposite lower second end 2f, next to each other and with respect to the usual handling of the control switch 1 positioned one above the other. The second control panel 4 provided in the area of the first end 2e of the housing 2 comprises an operating element in the form of a pushbutton, which represents an emergency stop button 4a. The control element or the emergency stop button 4a is preferably arranged in a strikingly outstanding manner, so that a particularly rapid and panic-proof triggering of an emergency stop is possible. In other words, the emergency stop button 4a in the present case protrudes from the front 2a of the housing 2, so that it can be quickly grasped and operated (see also Figures 2 and 5 ).

Auf der vom ersten Ende 2e des Gehäuses 2 abgewandten Seite des zweiten Bedienfelds 4 ist an der Vorderseite 2a das erste Bedienfeld 3 angeordnet, das ein Bedienelement in Form einer Taste 3a für die Funktion "Kranfahrt vorwärts" eines Kranfahrwerks, ein Bedienelement in Form einer Taste 3b für die Funktion "Kranfahrt rückwärts" eines Kranfahrwerks, ein Bedienelement in Form einer Taste 3c für die Funktion "Katzfahrt rechts" eines Katzfahrwerks und ein Bedienelement in Form einer Taste 3d für die Funktion "Katzfahrt links" eines Katzfahrwerks umfasst. Die runden beziehungsweise kreisrunden und gleich dimensionierten Bedienelemente 3a 3d sind sternförmig angeordnet. Damit liegen ihre jeweiligen Mittelpunkte auf zwei sich kreuzenden Diagonalen einer gedachten Raute, wobei die Diagonalen die Ecken der gedachten Raute miteinander verbinden. Der Steuerschalter 1 weist an der Vorderseite 2a eine Vertiefung in der Gehäusewand auf, deren Grundfläche im Wesentlichen der von den Diagonalen aufgespannten Raute entspricht. Die Bedienelemente 3a 3d sind in den Ecken der rautenförmigen Vertiefung mit geringem radialen Abstand zur die Vertiefung begrenzenden Gehäusewand angeordnet. Hierbei sind die Ecken der Vertiefung, beziehungsweise der Grundfläche, entsprechend abgerundet. Auch die Seiten beziehungsweise Kanten der gedachten Raute weisen nach Innen gerichtete, abgerundete Einbuchtungen auf. Die entlang einer parallel zur Längsrichtung L des Gehäuses 2 verlaufenden Längsachse x des ersten Bedienfelds 3 angeordneten Bedienelemente 3a, 3b sind insofern in Endbereichen der parallel zur Längsrichtung L des Gehäuses 2 ausgerichteten ersten Diagonale gelegen. Die entlang einer quer zur Längsrichtung L des Gehäuses 2 verlaufenden Querachse y des ersten Bedienfelds 3 angeordneten Bedienelemente 3c, 3d sind dabei in Endbereichen der rechtwinklig zu der ersten Diagonale ausgerichteten zweiten Diagonale gelegen. Insgesamt sind die Bedienelemente 3a 3d somit annähernd kreuzförmig und/oder rautenförmig angeordnet, so dass sich das in den Figuren 1 und 3 dargestellte, im Wesentlichen rautenförmige erste Bedienfeld 3 im Bereich der Vertiefung des Gehäuses 2 ergibt.On the side of the second control panel 4 facing away from the first end 2e of the housing 2, the first control panel 3 is arranged on the front side 2a Control element in the form of a button 3a for the function "crane travel forward" of a crane trolley, an control element in the form of a button 3b for the function "crane travel backward" of a crane trolley, an control element in the form of a button 3c for the function "trolley travel right" of a trolley carriage and comprises an operating element in the form of a button 3d for the function "trolley travel left" of a trolley. The round or circular and equally dimensioned control elements 3a 3d are arranged in a star shape. Thus, their respective centers lie on two intersecting diagonals of an imaginary diamond, the diagonals connecting the corners of the imaginary diamond with each other. The control switch 1 has a recess on the front side 2a in the housing wall, the base of which essentially corresponds to the diamond spanned by the diagonals. The control elements 3a 3d are arranged in the corners of the diamond-shaped depression with a small radial distance from the housing wall delimiting the depression. The corners of the depression or the base are rounded off accordingly. The sides or edges of the imaginary diamond also have rounded indentations facing inwards. The control elements 3a, 3b arranged along a longitudinal axis x of the first control panel 3 running parallel to the longitudinal direction L of the housing 2 are in this respect located in end regions of the first diagonal aligned parallel to the longitudinal direction L of the housing 2. The control elements 3c, 3d arranged along a transverse axis y of the first control panel 3 running transversely to the longitudinal direction L of the housing 2 are located in end regions of the second diagonal oriented at right angles to the first diagonal. Overall, the operating elements 3a, 3d are thus arranged approximately in a cross shape and / or in a diamond shape, so that this can be seen in FIGS Figures 1 and 3rd shown, essentially diamond-shaped first control panel 3 in the region of the recess of the housing 2.

Im vorliegenden Ausführungsbeispiel sind die koaxial zu der Längsachse x und Querachse y verlaufenden Diagonalen ungleich lang, so dass die gedachte Raute, beziehungsweise die Grundfläche der Vertiefung, ein Rechteck beziehungsweise Parallelogramm mit entsprechenden abgerundeten Ecken und entsprechend abgerundeten Kanten darstellt. Die Vertiefung ist in Richtung des zweiten Endes 2f unterhalb der Taste 3b zum dritten Bedienfeld 5 hin offen. Das erste Bedienfeld 3 und das dritte Bedienfeld 5 sind somit gemeinsam in einer durchgehenden Vertiefung angeordnet.In the present exemplary embodiment, the diagonals running coaxially to the longitudinal axis x and transverse axis y are of unequal length, so that the imaginary rhombus, or the base area of the depression, represents a rectangle or parallelogram with corresponding rounded corners and correspondingly rounded edges. The recess is open towards the third control panel 5 in the direction of the second end 2f below the button 3b. The first control panel 3 and the third control panel 5 are thus arranged together in a continuous depression.

Das dritte Bedienfeld 5 ist auf der dem zweiten Ende 2f des Gehäuses 2 zugewandten Seite des ersten Bedienfelds 3 positioniert. Das Bedienfeld 5 umfasst als Bedienelemente eine Taste 5a für die Funktion "Heben" eines Hubwerks und - hiervon in Richtung des zweiten Endes 2f beabstandet - eine Taste 5b für die Funktion "Senken" eines Hubwerks. Die Bedienelemente 5a, 5b für ein Hubwerk sind hierbei zentriert entlang einer gedachten Geraden angeordnet, die parallel zur Längsrichtung L des Gehäuses 2 und insbesondere fluchtend mit der ersten Diagonalen beziehungsweise Längsachse x des zweiten Bedienfelds 4 ausgerichtet ist. Auch diese Bedienelemente 5a, 5b sind rund beziehungsweise kreisrund und gleich dimensioniert sowie in der von dem Bedienfeld 3 ohne Unterbrechung durchlaufenden, an der Vorderseite 2a ausgebildeten länglichen Vertiefung in der Gehäusewand angeordnet. Entsprechend der runden Form des Bedienelements 5b ist das Längsende der Vertiefung abgerundet. Dabei ist der Radius der Abrundung so gewählt, dass jene, die Vertiefung begrenzenden Gehäusewände auch hier so weit von dem Bedienelement 5b beabstandet sind, dass ausreichend Raum zu dessen händischer Betätigung verbleibt. Das Längsende der Vertiefung ist außerdem so ausgebildet, dass der Daumen einer Bedienerhand, der von dem unteren zweiten Ende 2f kommend auf der Vorderseite 2a des Steuerschalters 1 entlang gleitet, über ein Gefälle G, das insbesondere im Vergleich zur übrigen Begrenzung der Vertiefung eine flachere Steigung aufweist, in die Vertiefung und zum dritten Bedienfeld 5 geführt wird. Vorzugsweise sind alle sechs Bedienelemente 3a 3d; 5a, 5b der beiden vorgenannten ersten und zweiten Bedienfelder 3, 5 gleich dimensioniert und insbesondere als ein- oder mehrstufige Drucktasten ausgebildet. Auch eine stufenlose Ausbildung der Drucktasten ist vorstellbar.The third control panel 5 is positioned on the side of the first control panel 3 facing the second end 2f of the housing 2. The control panel 5 comprises, as operating elements, a key 5a for the "lifting" function of a lifting mechanism and - at a distance therefrom in the direction of the second end 2f - a key 5b for the "lowering" function of a lifting mechanism. The controls 5a, 5b for a hoist are arranged centered along an imaginary straight line that is aligned parallel to the longitudinal direction L of the housing 2 and in particular in alignment with the first diagonal or longitudinal axis x of the second control panel 4. These control elements 5a, 5b are also round or circular and have the same dimensions and are arranged in the elongated recess in the housing wall, which the control panel 3 traverses without interruption and is formed on the front side 2a. According to the round shape of the control element 5b, the longitudinal end of the depression is rounded. The radius of the rounding is selected such that the housing walls delimiting the recess are also so far away from the operating element 5b that there is sufficient space for its manual actuation. The longitudinal end of the depression is also designed such that the thumb of an operator's hand, which comes from the lower second end 2f, slides along the front 2a of the control switch 1, over a slope G, which in particular has a flatter slope compared to the rest of the depression has, is led into the recess and to the third control panel 5. All six control elements 3a, 3d are preferably; 5a, 5b of the two aforementioned first and second control panels 3, 5 have the same dimensions and in particular are designed as single-stage or multi-stage pushbuttons. A continuous formation of the push buttons is also conceivable.

Die vorgenannten Bedienelemente 3a 3d; 4a; 5a, 5b oder die Nahbereiche der Bedienelemente 3a 3d; 4a; 5a, 5b auf der Vorderseite 2a können mit vorliegend nur beispielhaft gezeigten und insofern nicht darauf eingeschränkten Symbolen und/oder Beschriftungen versehen sein, die auf die Funktion des jeweiligen Bedienelements 3a 3d; 4a; 5a, 5b hinweisen. Weitere Details zur Form und Anordnung der Bedienfelder 3 5 und der zugehörigen Bedienelemente 3a 3d; 4a; 5a, 5b sind in den Figuren dargestellt.The aforementioned controls 3a 3d; 4a; 5a, 5b or the vicinity of the control elements 3a 3d; 4a; 5a, 5b on the front side 2a can be provided with symbols and / or inscriptions which are only shown here by way of example and are therefore not restricted to them, and which relate to the function of the respective operating element 3a 3d; 4a; 5a, 5b. Further details on the shape and arrangement of the control panels 3 5 and the associated control elements 3a 3d; 4a; 5a, 5b are shown in the figures.

Die Kontur des Steuerschalters 1 beziehungsweise des Gehäuses 2 und die zuvor beschriebenen Bedienfelder 3 5 sind wie nachfolgend beschrieben in Bezug auf ihre Form und Anordnung ergonomisch vorteilhaft aufeinander abgestimmt. In den Figuren 1 bis 4 ist erkennbar, dass das Gehäuse 2 des Steuerschalters 1 zwischen seinen beiden Längsenden 2e, 2f eine in Längsrichtung L profilierte Form aufweist, die vorzugsweise zwei unmittelbar aufeinanderfolgende bikonvex zueinander gekrümmte Verläufe 13a, 13b der Längsseiten 2c, 2d und eine zwischen diesen gelegene Einschnürung 11 umfasst. Im Bereich des ersten Bedienfelds 3 sind die von außen gesehen konvexen Verläufe 13a, 13b des Gehäuses 2 des Steuerschalters 1 breiter als in der Einschnürung 11. Ausgehend von dem ersten Ende 2e und der dort angeordneten oder anordenbaren sowie nicht näher gezeigten Steuerleitung erstrecken sich die Längsseiten 2c, 2d zunächst jeweils von der Längsrichtung L weg und anschließend wieder zur Längsrichtung L in Richtung des zweiten Endes 2f hin. Zwischen den Längsseiten 2c, 2d, welche die bikonvex zueinander gekrümmten Verläufe 13b aufweisen, ist das zweite Bedienfeld 4 angeordnet. An diese von außen gesehen konvexen Verläufe 13b schließt sich dann die Einschnürung 11 an (siehe insbesondere Figur 3). Nach der Einschnürung 11 schließen sich die weiteren von außen gesehen konvexen Verläufe 13a der Längsseiten 2c, 2d an, wobei sich die Längsseiten 2c, 2d im Bereich des ersten Bedienfelds 3 in Bezug auf die Längsrichtung L des Steuerschalters 1 jeweils von der Längsrichtung L weg und anschließend zur Längsrichtung L hin erstrecken. Im Bereich der Einschnürung 11 gehen die Längsseiten 2c, 2d im Sinne eines Knicks beziehungsweise knickförmig von einem bikonvex zueinander gekrümmten Verlauf 13b in den nächsten bikonvex zueinander gekrümmten Verlauf 13a über.The contour of the control switch 1 or the housing 2 and the previously The control panels 35 described are ergonomically advantageously coordinated with one another as described below in terms of their shape and arrangement. In the Figures 1 to 4 It can be seen that the housing 2 of the control switch 1 has a shape profiled in the longitudinal direction L between its two longitudinal ends 2e, 2f, which preferably comprises two immediately successive biconvex curves 13a, 13b of the longitudinal sides 2c, 2d and a constriction 11 located between them . In the area of the first control panel 3, the convex courses 13a, 13b of the housing 2 of the control switch 1 seen from the outside are wider than in the constriction 11. Starting from the first end 2e and the control line arranged or arranged there and not shown in detail, the longitudinal sides extend 2c, 2d first away from the longitudinal direction L and then again towards the longitudinal direction L in the direction of the second end 2f. The second control panel 4 is arranged between the long sides 2c, 2d, which have the biconvex curves 13b. The constriction 11 then adjoins these convex curves 13b when viewed from the outside (see in particular Figure 3 ). After the constriction 11, the further convex courses 13a of the long sides 2c, 2d, seen from the outside, follow, the long sides 2c, 2d in the area of the first control panel 3 with respect to the long direction L of the control switch 1 and away from the long direction L and then extend in the longitudinal direction L. In the area of the constriction 11, the long sides 2c, 2d transition from a biconvex curve 13b to the next biconvex curve 13a in the sense of a bend or kink.

An den ersten von außen gesehen konvexen Verlauf 13a schließt sich in Richtung des zweiten Endes 2f ein geradliniger Verlauf der sich dabei parallel zueinander erstreckenden Längsseiten 2c, 2d an. Der Übergang beziehungsweise Verlauf 12 zwischen dem ersten bikonvex zueinander gekrümmten Verlauf 13a und dem geradlinigen Verlauf hin zum zweiten Ende 2f des Steuerschalters 1 ist bikonkav zueinander gekrümmt und unterscheidet sich damit in seiner Form von dem abrupten Übergang der knickförmigen Einschnürung 11 zwischen dem ersten bikonvex zueinander gekrümmten Verlauf 13a und dem zweiten bikonvex zueinander gekrümmten Verlauf 13b. Der bikonkav zueinander gekrümmte Verlauf 12 des Übergangs stellt einen weniger harten beziehungsweise einen sanfteren Übergang zwischen den beiden Verläufen dar. Mit anderen Worten ist der Steuerschalter 1 durch diesen Aufbau im Bereich des ersten Bedienfelds 3 und des zweiten Bedienfelds 4 breiter als im Bereich des dritten Bedienfelds 5.In the direction of the second end 2f, the first convex course 13a seen from the outside is followed by a straight course of the longitudinal sides 2c, 2d which extend parallel to one another. The transition or course 12 between the first biconvex curve 13a and the straight course towards the second end 2f of the control switch 1 is biconcavely curved and thus differs in shape from the abrupt transition of the kink-shaped constriction 11 between the first biconvex curve Course 13a and the second biconvex course 13b. The biconcavely curved course 12 of the transition represents a less hard or a gentler transition between the two courses. In other words, the control switch 1 this construction makes it wider in the area of the first control panel 3 and the second control panel 4 than in the area of the third control panel 5.

Eine Rückseite 2b des Steuerschalters 1 ist in den Figuren 2 sowie 4 und in Bezug auf deren Kontur in Figur 5 dargestellt. Der Verlauf der Längsseiten 2c, 2d entlang der Rückseite 2b entspricht im Wesentlichen dem Verlauf der Längsseiten 2c, 2d entlang der Vorderseite 2a. Die Rückseite 2b ist im Wesentlichen durchgehend und vom unteren zweiten Ende 2f ausgehend bis zum Bereich des ersten Bedienfeldes 3 eben ausgestaltet, wobei diese selbstverständlich auch eine abgerundete Form aufweisen kann. Die Rückseite 2b weist insbesondere keine gegenüber dieser zurückspringende Vertiefungen auf, sondern umfasst zwei gegenüber der Rückseite 2b erhöhte Vorsprünge 9a, 9b.A rear 2b of the control switch 1 is in the Figures 2 as well as 4 and with regard to their contour in Figure 5 shown. The course of the long sides 2c, 2d along the rear 2b essentially corresponds to the course of the long sides 2c, 2d along the front 2a. The rear 2b is essentially continuous and flat from the lower second end 2f to the area of the first control panel 3, which of course can also have a rounded shape. The rear side 2b has in particular no recesses recessed relative to it, but rather comprises two projections 9a, 9b raised relative to the rear side 2b.

Ein erster dieser Vorsprünge 9a ist dementsprechend an der Rückseite 2b bezogen auf die Längsrichtung L des Steuerschalters 1 im Bereich des ersten Bedienfelds 3 angeordnet. Der erste Vorsprung 9a liegt also dem ersten Bedienfeld 3, insbesondere dem Bedienelement 3b, rückseitig gegenüber. Konkret liegt der erste Vorsprung 9a dabei auf Höhe des Bedienelements 3b, welches in Richtung des zweiten Endes beziehungsweise Längsendes 2f unterhalb der zwei entlang der Querachse y nebeneinander angeordneten Bedienelemente 3c, 3d gelegen ist. Die zweite der beiden rückseitigen Vorsprünge 9b ist im entsprechenden Bereich des dritten Bedienfelds 5, insbesondere rückseitig in einem Bereich gegenüber der Taste 5b und/oder des dem ersten Bedienfeld 3 abgewandten unteren Bereichs des dritten Bedienfelds 5, angeordnet. Die profilierte Kontur der Vorsprünge 9a und 9b erstreckt sich hierbei senkrecht von der Rückseite 2b weg und insbesondere zwischen den beiden Längsseiten 2c, 2d, so dass dagegen beispielsweise ein Zeigefinger einer den Steuerschalter haltenden Bedienerhand intuitiv angelegt werden kann. Bei ausreichender Profilierung, die sich insbesondere über die ganze Breite der Rückseite 2b erstreckt, kann hierdurch eine ergonomisch vorteilhafte Zwangslage einer Bedienerhand erreicht werden.A first of these projections 9a is accordingly arranged on the rear 2b in relation to the longitudinal direction L of the control switch 1 in the region of the first control panel 3. The first projection 9a thus lies opposite the first control panel 3, in particular the control element 3b. Specifically, the first projection 9a lies at the level of the control element 3b, which is located in the direction of the second end or longitudinal end 2f below the two control elements 3c, 3d arranged alongside the transverse axis y. The second of the two rear projections 9b is arranged in the corresponding area of the third control panel 5, in particular on the rear in an area opposite the key 5b and / or the lower area of the third control panel 5 facing away from the first control panel 3. The profiled contour of the projections 9a and 9b extends perpendicularly away from the rear 2b and in particular between the two longitudinal sides 2c, 2d, so that, for example, an index finger of an operator's hand holding the control switch can be intuitively placed. With sufficient profiling, which extends in particular over the entire width of the back 2b, an ergonomically advantageous constrained position of an operator's hand can be achieved.

In den Figuren 1, 2, 5 und 6 ist ersichtlich, dass das Gehäuse 2 aus zwei schalenförmigen Gehäusehälften zusammengesetzt sein kann. Hierbei umfasst eine Gehäusehälfte die Vorderseite 2a und zumindest einen Teil der Längsseiten 2c, 2d und die andere Gehäusehälfte umfasst die Rückseite 2b und einen zweiten Teil der Längsseiten 2c, 2d. Das Gehäuse 2 beziehungsweise die Gehäuseschalen können beispielsweise ein bei Raumtemperatur formstabiles Kunststoffmaterial aufweisen und insbesondere mittels eines Kunststoffspritzgussverfahrens hergestellt sein. Am ersten Längsende 2e umschließt eine flexible Knicksicherung der angeschlossenen oder anschließbaren Steuerleitung die beiden Gehäuseschalen. Am zweiten Längsende 2f ist ein zweites Endteil 6 angebracht, dass das Gehäuse 2 stirnseitig am Längsende 2f als separates Teil nach Art einer Kappe abschließt und hierbei mit beiden Gehäuseschalen rastend zusammengesteckt werden kann.In the Figures 1 , 2nd , 5 and 6 it can be seen that the housing 2 can be composed of two shell-shaped housing halves. Here, one housing half comprises the front side 2a and at least part of the long sides 2c, 2d and the other housing half comprises the rear side 2b and a second part of the Long sides 2c, 2d. The housing 2 or the housing shells can, for example, have a plastic material that is dimensionally stable at room temperature and can be produced in particular by means of a plastic injection molding process. At the first longitudinal end 2e, a flexible kink protection of the connected or connectable control line encloses the two housing shells. A second end part 6 is attached to the second longitudinal end 2f, so that the housing 2 closes at the end at the longitudinal end 2f as a separate part in the manner of a cap and can be snapped together with both housing shells.

Insbesondere in Figur 5 ist zudem dargestellt, dass sich die Vorderseite 2a und die Rückseite 2b vom unteren Längsende 2f bis zum oberen Vorsprung 9a eben und parallel zueinander erstrecken. Oberhalb des oberen, ersten Vorsprungs 9a ist die Rückseite 2b bauchförmig beziehungsweise von außen gesehen konvex und somit in diesem Bereich nicht mehr parallel zu der Vorderseite 2a ausgebildet. Ein unterer erster Abschnitt 8a des Steuerschalters 1, umfassend das erste und dritte Bedienfeld 3, 5, erstreckt sich unterhalb der Einschnürung 11 bis zum unteren Ende 2f beziehungsweise dem Endteil 6. Ein oberer zweiter Abschnitt 8b, umfassend das zweite Bedienfeld 4, erstreckt sich von der angeschlossenen oder anschließbaren Steuerleitung bis zur Einschnürung 11. Erkennbar sind die beiden Abschnitte 8a, 8b zueinander abgewinkelt, wobei sie einen Winkel W zwischen sich einschließen.Especially in Figure 5 it is also shown that the front side 2a and the rear side 2b extend flat and parallel to one another from the lower longitudinal end 2f to the upper projection 9a. Above the upper, first projection 9a, the rear side 2b is bulge-shaped or, seen from the outside, is convex and therefore no longer parallel to the front side 2a in this region. A lower first section 8a of the control switch 1, comprising the first and third control panels 3, 5, extends below the constriction 11 to the lower end 2f or the end part 6. An upper second section 8b, comprising the second control panel 4, extends from of the connected or connectable control line up to the constriction 11. It can be seen that the two sections 8a, 8b are angled to one another, enclosing an angle W between them.

Ein weiteres Ausführungsbeispiel ist in der Figur 6 dargestellt. Analog zur Figur 1 zeigt die Figur 6 den Steuerschalter 1 in einer perspektivischen Ansicht mit seiner Vorderseite 2a und einer seiner Längsseiten 2d. Einziger Unterschied zur Figur 1 ist, dass das erste Bedienfeld 3 nicht vier Bedienelemente 3a 3d umfasst, sondern lediglich die zwei in Querrichtung y nebeneinander angeordneten Bedienelemente für die Funktion "Katzfahrt rechts" 3c und "Katzfahrt links" 3d. Im Ausführungsbeispiel gemäß Figur 6 entfallen die Bedienelemente für die Funktion "Kranfahrt vorwärts" und "Kranfahrt rückwärts", wodurch die vorgesehenen Positionen innerhalb des Bedienfeldes 3 dementsprechend keine solchen Bedienelemente 3a, 3b aufweisen. Ansonsten gilt das zu der vorherigen Ausführungsform gemäß den Figuren 1 bis 5 Gesagte analog für die Ausführungsform gemäß Figur 6.Another embodiment is in the Figure 6 shown. Analogous to Figure 1 show the Figure 6 the control switch 1 in a perspective view with its front 2a and one of its long sides 2d. The only difference to Figure 1 is that the first control panel 3 does not include four control elements 3a 3d, but only the two control elements arranged next to one another in the transverse direction y for the functions "trolley travel right" 3c and "trolley travel left" 3d. In the embodiment according to Figure 6 the control elements for the functions "crane travel forward" and "crane travel backward" are omitted, as a result of which the intended positions within the control panel 3 accordingly do not have such control elements 3a, 3b. Otherwise, this applies to the previous embodiment according to FIGS Figures 1 to 5 Said analogously for the embodiment according to Figure 6 .

Auch ist vorgesehen, dass der Steuerschalter 1 beziehungsweise dessen Gehäuse 2 zumindest bereichsweise oder vollständig, insbesondere an seiner Außenseite und insbesondere im Greifbereich an der Rückseite 2b sowie den Längsseiten 2c, 2d, mit einem so genannten Soft-Coating versehen ist, das heißt mit einer Beschichtung, die weicher ist als das Gehäuse 2. Zur Herstellung eines solchen Soft-Coatings eignen sich beispielsweise Mehrkomponenten-Lacke, insbesondere so genannte Polysoft-Lacke.It is also provided that the control switch 1 or its housing 2 at least partially or completely, in particular on its outside and in particular in the gripping area on the back 2b and the long sides 2c, 2d, is provided with a so-called soft coating, that is to say with a coating which is softer than the housing 2. For example, multi-component coatings are suitable for producing such a soft coating. Lacquers, especially so-called Polysoft lacquers.
