Description
Die vorliegende Erfindung betrifft eine Positioniervorrichtung mit Auslösevermittlung für ein über einen Auslöseelement betätigbares handgeführtes Setzgerät der im Oberbegriff des Patentanspruchs 1 genannten Art. Derartige Positioniervorrichtungen mit Auslösevermittlung werden z. B. bei der Überkopfmontage mit handgeführten Setzgeräten an hohen Decken verwendet, wo ansonsten nur ein Arbeiten mittels Arbeitsbühnen oder Leitern möglich wäre. Die mit der Positioniervorrichtung verwendbaren Setzgeräte können z. B. mit festen, gasförmigen oder flüssigen Brennstoffen oder auch mit Druck- oder Pressluft oder elektrisch betrieben werden.The present invention relates to a positioning device with tripping mediation for an actuatable via a trigger element hand-held setting tool referred to in the preamble of
Aus der
Von Nachteil hierbei ist jedoch, dass das Auslösen des Setzgerätes nur sicher verhindert werden kann, wenn die Positionier- und Auslösevorrichtung mit dem Setzgerät exakt mit der Mündung in Richtung der Gravitationskraft ausgerichtet ist.The disadvantage here, however, that the release of the setting device can only be reliably prevented when the positioning and release device is aligned with the setting device exactly to the mouth in the direction of gravitational force.
Aus der
Von Nachteil bei diesem Setzgerät ist jedoch, dass beim Anpressen in der Sperrstellung auf die für die Sperrfunktion notwendigen Teile hohe Kräfte ausgeübt werden, die auf Dauer zu Verschleiss führen können und die die Wirksamkeit der Sicherheitssperreinrichtung herabsetzen können.A disadvantage of this setting tool, however, is that when pressing in the blocking position on the parts necessary for the blocking function high forces are exerted, which can lead to wear in the long term and can reduce the effectiveness of the Sicherheitsperperreinrichtung.
Die Aufgabe der vorliegenden Erfindung liegt daher darin, eine Positionier- und Auslösevorrichtung der vorgenannten Art zu entwickeln, welche die genannten Nachteile vermeidet, die störungsfrei arbeitet und den Verschleiss minimiert.The object of the present invention is therefore to develop a positioning and tripping device of the aforementioned type, which avoids the disadvantages mentioned, which operates without interference and minimizes wear.
Erfindungsgemäss wird die gestellte Aufgabe durch eine Positioniervorrichtung mit Auslösevermittlung für ein über einen Auslöseschalter betätigbares handgeführtes Setzgerät mit den Merkmalen des unabhängigen Anspruchs gelöst. Demnach weist die Sicherheitseinrichtung ein zwischen einem ersten Stellelement und einem zweiten Stellelement des Schaltstranges positionierbares gravitationsgesteuertes Zwischenelement auf, das in einer Auslösevermittlungsstellung kupplungswirksam zwischen dem ersten Stellelement und dem zweiten Stellelement positioniert ist und das in einer Unterbrechungsstellung den Schaltstrang unterbricht. In der Auslösevermittlungsstellung sind das erste und das zweite Stellelement also über das Zwischenelement zur Weiterleitung einer Schaltbewegung koppelbar, während in der Unterbrechungsstellung eine Kopplung des ersten und des zweiten Stellelementes nicht möglich ist. Gravitationsgesteuert im Sinne der Erfindung heisst dabei, dass das Zwischenelement unter der Einwirkung der Gravitationskraft bewegbar ist, wenn sich die relative Lage bzw. Orientierung der Positioniervorrichtung zum Vektor der Gravitationskraft verändert.According to the invention, the stated object is achieved by a positioning device with a triggering device for an actuatable via a trigger switch hand-held setting device having the features of the independent claim. Accordingly, the safety device has a positionable between a first actuator and a second actuator of the shift string gravitationally controlled intermediate element, which is positioned in a triggering switching position coupling effect between the first actuator and the second actuator and interrupts the switching path in an interruption position. In the tripping mediation position, the first and the second control element can thus be coupled via the intermediate element for relaying a switching movement, while in the interruption position a coupling of the first and the second control element is not possible. Gravity-controlled according to the invention means that the intermediate element is movable under the action of the gravitational force, when the relative position or orientation of the positioning device to the vector of the gravitational force changes.
Dadurch dass keine sperrwirksamen Bauteile vorgesehen sind, die hohe Anpresskräfte aufnehmen müssen, sondern lediglich eine Unterbrechung des Schaltstranges erfolgt, ist kein nennenswerter Verschleiss der Sicherheitseinrichtung mehr zu erwarten. Das Zwischenelement ist vielmehr in der ausgerückten Position nicht mehr im Kraftfluss des Schaltstranges und wird nicht belastet, ebenso wie das zweite Stellelement und der hingegen nicht verhindert, sondern kann frei und ohne Widerstand durchgeführt werden, ohne dass das zweite Stellelement vom Kraftfluss erreicht würde.The fact that no barrier-effective components are provided, which must absorb high contact forces, but only an interruption of the switching string, no significant wear of the safety device is expected more. The intermediate element is rather no longer in the disengaged position in the power flow of the switching string and is not loaded, as well as the second actuator and the On the other hand, it can not be prevented, but can be carried out freely and without resistance, without the second actuating element being reached by the force flow.
Vorteilhaft sind das erste Stellelement und das zweite Stellelement entlang der Längsachse der Positioniervorrichtung bzw. der Handhabe verschiebbar in einer Führung gelagert, wodurch die Sicherheitseinrichtung sich leicht in die Handhabe oder in das Anbindungsmittel integrieren lässt, ohne radial ausladend zu bauen.Advantageously, the first control element and the second control element along the longitudinal axis of the positioning device or the handle are slidably mounted in a guide, whereby the safety device can be easily integrated into the handle or in the connection means, without building radially.
Von Vorteil ist es ferner, wenn wenigstens in einer Ausgangsstellung der Handhabe um einen Zwischenraum zwischen dem ersten Stellelement und dem zweiten Stellelement ein radial umlaufender Freiraum für das Zwischenelement in einem Gehäuseteil angeordnet ist. Hierdurch ergibt sich sowohl beim Anheben der Positioniervorrichtung entgegen der Gravitationskraft bis zum Einrücken des Zwischenelementes in den Schaltstrang als auch beim Absenken der Positioniervorrichtung in Richtung der Gravitationskraft bis zum Ausrücken des Zwischenelementes aus dem Schaltstrang ein gleich bleibender Grenzwinkel. Somit ist der Neigungswinkel bei dem das Auslösen einer Setzung noch möglich ist immer gleich, unabhängig von der zuvor beschriebenen Bewegung der Positioniervorrichtung. Das Gehäuseteil kann dabei Teil der Handhabe oder auch ein Teil des Anbindungsmittels sein oder beider sein.It is also advantageous if at least in a starting position of the handle about a gap between the first adjusting element and the second adjusting element, a radially encircling space for the intermediate element is arranged in a housing part. This results in both the lifting of the positioning against the gravitational force to the engagement of the intermediate element in the control strand as well as lowering the positioning in the direction of gravity until the disengagement of the intermediate element from the control strand a constant critical angle. Thus, the inclination angle at which the triggering of a settlement is still possible is always the same, regardless of the previously described movement of the positioning device. The housing part may be part of the handle or a part of the connection means or both.
Günstig ist es ferner, wenn das Zwischenelement als Kugel ausgebildet ist und das erste Stellelement eine Vertiefung für die Kugel aufweist. Hierdurch kann das Zwischenelement leicht durch die Gravitationskraft bewegt werden und gleichzeitig gut über die Vertiefung gefangen und bis zu einem bestimmten Neigungswinkel in Position gehalten werden.It is also advantageous if the intermediate element is designed as a ball and the first actuating element has a recess for the ball. In this way, the intermediate element can be easily moved by the gravitational force and at the same time caught well over the depression and held in position up to a certain angle of inclination.
In einer vorteilhaften Ausgestaltung ist die Vertiefung trichterförmig gestaltet und bildet eine Trichterfläche aus, wobei die Trichterfläche sich radial aussen in der Ausgangsstellung der Handhabe bündig an einer den Freiraum auf der dem zweiten Stellelement abgewandten Seite begrenzenden konischen Fläche anschliesst. Durch diese Massnahme kann das als Kugel ausgebildete Zwischenelement leicht von der Auslösevermittlungsstellung in die Unterbrechungsstellung und umgekehrt überführt werden, ohne dass es zu ungewollten Zwischenstellungen der Kugel kommt.In an advantageous embodiment, the depression is funnel-shaped and forms a funnel surface, wherein the funnel surface adjoins radially outward in the starting position of the handle flush with a conical surface delimiting the free space on the side facing away from the second actuating element. By this measure, the formed as a ball intermediate element can be easily transferred from the tripping mediation position in the interruption position and vice versa, without causing unwanted intermediate positions of the ball.
Eine günstige Auslegung der kugelgesteuerten Sicherheitseinrichtung ergibt sich, wenn die Trichterfläche einen ersten Winkel zu einer Normalen zur Längsachse ausbildet, der mit einer Toleranz von +/- 2 Grad einem zweiten Winkel der konischen Fläche zu der Normalen 30° wodurch eine maximale Neigung der Positioniereinrichtung zur Vertikalen von ebenfalls zwischen 15° und 30° möglich ist, bei der das Setzgerät noch über das Betätigungselement der Positioniereinrichtung ausgelöst werden kann.A favorable design of the ball-controlled safety device results when the funnel surface forms a first angle to a normal to the longitudinal axis, with a tolerance of +/- 2 degrees a second angle of the conical surface to the normal 30 ° whereby a maximum inclination of the positioning device to the vertical of also between 15 ° and 30 ° is possible, in which the setting device can still be triggered via the actuating element of the positioning device.
In einer vorteilhaften Variante der Sicherheitseinrichtung ist das Zwischenelement als Schwenkkörper ausgebildet, der über eine Schwenkverbindung verschwenkbar an dem zweiten Stellelement gelagert ist. Hierdurch wird eine geringe Anpresskraft ermöglicht, da der zur Betätigung des Setzgerätes zur Verfügung stehende maximale Hub des Schaltstranges über die gewählte axiale Länge des Schwenkkörpers einstellbar.In an advantageous variant of the safety device, the intermediate element is designed as a swiveling body, which is mounted pivotably on the second actuating element via a swivel connection. As a result, a small contact force is made possible because of the available for actuating the setting device maximum stroke of the switching strand over the selected axial length of the pivot body adjustable.
In einer technisch leicht umsetzbaren Ausgestaltung, ist die Schwenkverbindung über ein biegeelastisches Lagerelement gebildet, über das der Schwenkkörper mit dem zweiten Stellelement, verbunden ist. Der Schwenkkörper verhält sich dabei wie ein Pendel und kann unter der Einwirkung der Gravitationskraft frei verschwenken. Das biegeelastische Lagerelement kann dabei z. B. ein Faden oder dünner Draht sein.In a technically easily implementable embodiment, the pivot connection is formed via a flexurally elastic bearing element, via which the pivoting body is connected to the second control element. The swivel body behaves like a pendulum and can pivot freely under the influence of the gravitational force. The flexurally elastic bearing element can be z. As a thread or thin wire.
Vorteilhaft weist der Schwenkkörper an seinem der Schwenkverbindung gegenüberliegenden axialen Ende eine umlaufende konische Abgleitfläche auf, wobei an dem diesem axialen Ende gegenüberliegenden Ende des ersten Stellelements eine weitere umlaufende konische Abgleitfläche vorgesehen ist. Die Auslegung der konischen Flächen in Bezug auf ihren Konuswinkel zur axialen Erstreckung ist dabei vorzugsweise derart, dass bei einem Neigungswinkel der Positioniervorrichtung im Bereich von 15° bis 30°, vorzugsweise von 20°, zur Vertikalen das Zwischenelement und das erste Stellelement aneinander vorbei gleiten können, wodurch sich ein Grenzwinkel im Bereich von 15° bis 30°, vorzugsweise von 20°, ergibt, bei dem ein Setzvorgang über das Betätigungselement der Positioniervorrichtung noch ausgelöst werden kann.Advantageously, the swivel body has a peripheral conical sliding surface on its axial end opposite the swivel connection, wherein a further circumferential conical sliding surface is provided at the end of the first control element opposite this axial end. The design of the conical surfaces with respect to their cone angle to the axial extent is preferably such that at an inclination angle of the positioning device in the range of 15 ° to 30 °, preferably 20 ° to the vertical, the intermediate element and the first actuator can slide past each other , which results in a critical angle in the range of 15 ° to 30 °, preferably 20 °, in which a setting operation on the actuating element of the positioning device can still be triggered.
