Abstract

The sprung hinge for a door flap hinged on its upper edge e.g. an upper flap for a cupboard, has an angled lever (3) which grips the inside of the door flap. The lever is joined to other control levers hinged on the support frame and with a compressed spring (21) element attached to one lever. In the lower, closed position of the door the lever linkage is at a dead point with the spring vector holding the flap closed. By slightly opening the flap the spring vector moves to enable the spring to assist in the opening of the flap until, in the open position, the spring holds the flap open.

Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Vorrichtung zum Öffnen bzw. Anheben einer an einem Scharnier mit horizontaler Schwenkachse nach unten hängenden Türe gemäss Oberbegriff des Anspruchs 1. Ferner bezieht sich die Erfindung auf eine Türe mit einer solchen Vorrichtung.The invention relates to a device for opening or lifting one on a hinge with horizontal pivot axis downwards hanging door according to the preamble of Claim 1. Furthermore, the invention relates to a door with such a device.

Stand der TechnikState of the art

Möbelsysteme sind darauf ausgelegt, dass sie an die verschiedensten Bedürfnisse (räumlich, benutzungstechnisch etc.) angepasst werden können. Schrankelemente sollen z.B. nach Bedarf nicht nur in geringer bis mittlerer, sondern auch in grösserer Höhe montiert werden können, wobei die Schranktüre jeweils bequem betätigbar sein soll. Um z.B. höher liegende Elemente leicht zugänglich zu halten, sind Schwenktüren von Vorteil, die an einer an der oberen Kante des Elementes angeordneten Schwenkachse drehbar aufgehängt sind. Das heisst, im geschlossenen Zustand hängt die Türe im wesentlichen vertikal nach unten, so dass sie zum Öffnen hochgeschwenkt werden muss. Damit die Türe einerseits ohne grosse Kraftanstrengung geöffnet werden kann und andererseits in der geöffneten Stellung ohne Hilfe des Benutzers verharren kann, wird ein Türheber installiert.Furniture systems are designed to meet a wide variety of needs (spatial, user-technical etc.) can be adapted. Cabinet elements should e.g. mounted as needed not only in low to medium, but also at a greater height can be, with the cabinet door should be easily operable. For example, higher To keep lying elements easily accessible, swing doors are beneficial to one rotatably mounted on the upper edge of the element arranged pivot axis are. That is, when closed, the door hangs substantially vertically below so that it must be swung open to open. So that the door on the one hand can be opened without great effort and on the other hand in the open Position can remain without the help of the user, a door lift is installed.

Auf dem Markt sind Türheber erhältlich, welche mit einem Gasdruckzylinder arbeiten. Charakteristisch für solche Zylinder ist die begrenzte maximale Ausfahrgeschwindigkeit. Auch im Fall einer Unachtsamkeit ist die Verletzungsgefahr bei der Montage oder der Benutzung vernachlässigbar klein. Dies ist ein Vorteil gegenüber einer Stahlfeder, welche als solche keine inhärente Bewegungsdämpfung kennt.Door lifts are available on the market, which work with a gas cylinder. Characteristic for such cylinders is the limited maximum extension speed. Also in the case of carelessness, the risk of injury during installation or use negligible small. This is an advantage over a steel spring, which as such no inherent motion damping knows.

Scherengelenke und Scharniere, die von Federn betätigt oder unterstützt sind, sind schon in grosser Zahl bekannt. Sie sind aber nicht für Türen konstruiert, welche an einem obenliegenden Scharnier aufgehängt sind und aus einer im wesentlichen vertikalen in eine im wesentlichen horizontale Stellung geschwenkt werden sollen. Scissor hinges and hinges that are operated or supported by springs are already known in large numbers. But they are not designed for doors that are on an overhead Hinge are suspended and from a substantially vertical to an in essential horizontal position to be pivoted.

Rein technisch betrachtet ist der Gasdruckzylinder einer Stahlfeder aber unterlegen. Nicht nur ist die mittlere Lebensdauer eines Gasdruckzylinders um einiges kürzer als diejenige einer Stahlfeder, sondern es ist auch die Entsorgung aufwendiger.Technically, however, the gas cylinder is inferior to a steel spring. Not only the average life of a gas cylinder is much shorter than that a steel spring, but it is also the disposal consuming.

Aus der DE 1 584 178 ist ein federgedämpftes Scharnier bekannt, bei welchem eine Kurvenfläche, welche im Bereich des Kniegelenks an einem der beiden Kniehebel ausgebildet ist, an einem Führungsbolzen abrollt. In der Schliesslage ist die Feder gespannt und durch den Führungsbolzen blockiert. In der Offenlage ist der Kniehebel gestreckt, wobei die Druckfeder erneut durch einen Bolzen blockiert wird.From DE 1 584 178 a spring-damped hinge is known in which a cam surface, which is formed in the region of the knee joint on one of the two toggle levers is rolling on a guide pin. In the closed position, the spring is stretched and through blocked the guide pin. In the open position, the toggle is stretched, with the Compression spring is blocked again by a bolt.

Die US 4,516,813 zeigt ein Scharnier für eine im geschlossenen Zustand nach unten hängende und im offenen Zustand horizontal vorstehende Türklappe, welche zudem versenkbar ausgeführt ist. Damit ist die Grundfunktionalität dieselbe wie bei der Erfindung. Es kommt ein Gelenkviereck zur Anwendung. Der Winkelhebel, welcher die Türe stützt, ist nicht um eine feststehende mechanische Achse drehbar, sondern wird durch zwei kurze Schwenkarme im Raum verschoben und gedreht. Zum Ausbalancieren der Bewegung ist eine Blattfeder vorgesehen, welche mehr oder weniger parallel neben den beiden kurzen Schwenkarmen verläuft und direkt am Ende des die Türe stützenden Winkelhebels angreift.US 4,516,813 shows a hinge for a downwards hanging in the closed state and in the open state horizontally projecting door flap, which also retractable is executed. Thus, the basic functionality is the same as in the invention. It a four-bar linkage is used. The angle lever which supports the door is not rotatable about a fixed mechanical axis, but is characterized by two short Swivel arms in the room moved and rotated. To balance the movement is a leaf spring is provided, which is more or less parallel beside the two short ones Swivel arms runs and attacks directly at the end of the door supporting the angle lever.

Die DE-OS 2 106 614 zeigt ein Kniehebel-Scharnier, bei welchem der die Türe stützende Arm am hinteren Ende eine Kulissenführung mit einer kürzeren und einer längeren Kurvenbahn aufweist. In der langlochartigen Kulisse ist das Ende eines federgestützten Arms verschiebbar gelagert. Beim Öffnen und Schliessen der Türklappe springt der gefederte Arm vom einen Kulissenabschnitt in den anderen.DE-OS 2 106 614 shows a toggle hinge in which the door supporting Arm at the rear end a sliding guide with a shorter and a longer curved path having. In the slot-like backdrop, the end of a spring-supported arm is slidable stored. When opening and closing the door flap, the spring-loaded arm jumps from one set of scenes to the other.

Die DE 2 151 935 A zeigt einen Mechanismus für einen Kofferraumdeckel bzw. eine Gepäckraumtür eines Omnibusses. Die Türe ist durch einen Kniehebel mit einem langen und einem kurzen Schenkel geführt. Am langen Schenkel greift eine am Fahrzeug abgestützte Feder an, so dass das Gewicht der Türe beim Anheben aus der vertikal hängenden in die horizontal vorstehende Position kompensiert wird. DE 2 151 935 A shows a mechanism for a trunk lid or a Luggage compartment door of a bus. The door is through a toggle with a long and a short leg. On the long leg one engages the vehicle supported spring so that the weight of the door when lifting from the vertical hanging in the horizontal projecting position is compensated.

Darstellung der ErfindungPresentation of the invention

Aufgabe der Erfindung ist es, eine Vorrichtung der eingangs genannten Art anzugeben, welche einerseits die Nachteile der bekannten Türheber vermeidet und andererseits nicht nur eine angemessene Kraftentwicklung aufweist (so dass die Türe nicht unkontrolliert auf- oder zuschlagen kann), sondern auch kompakt im Aufbau ist.The object of the invention is to provide a device of the type mentioned, which on the one hand avoids the disadvantages of the known door lifter and on the other hand not only has an adequate force development (so that the door does not open in an uncontrolled manner) or can strike), but is also compact in construction.

Gemäss der Erfindung zeichnet sich die Konstruktion des Türhebers durch einen Kniehebelmechanismus aus, welcher bei geschlossener Türe im Bereich seines Totpunktes und bei geöffneter Türe in seinem Kraftübertragungsmaximum ist. Als Antrieb bzw. Kraftelement ist eine Feder (z.B. eine Schraubenfeder) vorgesehen.The solution of the problem is defined by the features of claim 1. According to the Invention, the construction of the door lifter is characterized by a toggle mechanism off, which with the door closed in the area of its dead center and opened Door is in its power transmission maximum. As a drive or force element is a spring (e.g., a coil spring).

Der Kniehebel sorgt für eine dosierte Übertragung der Federkraft. Bei geschlossener Türe ist die Feder zwar gespannt, der im bzw. nahe am Totpunkt befindliche Kniehebel verhindert aber, dass die Kraft zur Entfaltung kommen kann. Beim Öffnen der Türe kommt der Kniehebel schon nach einer kurzen Bewegung aus dem Totpunkt und wirkt mit zunehmendem Öffnungswinkel mit grösserem Drehmoment. Die Hebelverhältnisse lassen sich so festlegen, dass das vom Türheber ausgeübte Drehmoment nur geringfügig grösser als das entgegengesetzte Drehmoment der Türe ist. Im Verlauf einer 90°-Schwenkbewegung kann die Türe folglich (selbst wenn sie sich selbst überlassen wird) gar nicht auf eine hohe Geschwindigkeit beschleunigt werden.The knee lever ensures a metered transmission of the spring force. When the door is closed Although the spring is tensioned, prevents the located in or near dead center knee lever but that the power can unfold. When you open the door comes the Knee lever after a short movement from the dead center and acts with increasing Opening angle with greater torque. The leverages can be so specify that the torque exerted by the door lifter is only slightly larger than that opposite torque of the door is. In the course of a 90 ° pivoting movement can the door is therefore not at a high speed (even if left to itself) be accelerated.

Der Mechanismus ist so gestaltet, dass der eine Schenkel des Kniehebels an einem Hebelelement gebildet ist, welches die Türe zum Öffnen kontaktiert. Das Hebelelement ist in einem Punkt drehbar gelagert, welcher einen gewissen Abstand zur Schwenkachse der Türe hat.The mechanism is designed so that the a leg of the toggle lever is formed on a lever element, which is the door to Open contacted. The lever element is rotatably mounted in a point which a has a certain distance from the pivot axis of the door.

Bezogen auf den Drehpunkt des Hebels sind der Kontaktpunkt (zwischen Hebel und Türe) und der Gelenkpunkt (des Kniegelenkes) um einen Winkel von z.B. etwa 90° oder etwas weniger gegeneinander versetzt. Relative to the pivot point of the lever are the contact point (between lever and door) and the articular point (of the knee joint) at an angle of e.g. about 90 ° or something less offset against each other.

Der zweite Schenkel des Kniehebels ist mit seinem freien (hinteren) Ende an einen einarmigen Führungshebel angelenkt. D.h. es wird ein Gelenkviereck gebildet, dessen eine Ecke gegen innen (in den Bereich des Kniehebel-Totpunktes) knicken kann.The second leg of the toggle lever is with its free (rear) end to a one-armed Guide lever articulated. That a four-bar linkage is formed, one of them Corner against the inside (in the area of the toggle dead center) can bend.

Die den Kniehebelmechanismus betätigende Druckfeder (komprimierte Spiralfeder) setzt gemäss einer besonders bevorzugten Ausführungsform am Führungshebel an. Es ist aber auch denkbar, dass die Feder an einem anderen Ort am Kniehebelmechanismus angreift. Insbesondere könnte sie direkt am zweiten Schenkel ansetzen bzw. in einer Verlängerung desselben angeordnet sein.The toggle mechanism actuating compression spring (compressed coil spring) sets according to a particularly preferred embodiment on the guide lever. But it is also conceivable that the spring engages at a different location on the toggle mechanism. In particular, it could start directly on the second leg or in an extension be arranged.

Der erste Schenkel des Kniehebels ist z.B. kürzer als der zweite. Dadurch kann die Belastung des Türscharniers (welche durch den Abstand des durch den Türheber unterstützten Punktes der Türe von der Achse des Scharniers mitbestimmt wird) reduziert werden. Vorzugsweise ist das Verhältnis der effektiven Längen etwa 2 : 3. Selbstverständlich können die Hebelverhältnisse variiert werden, um die Kraftübertragung an das variable Drehmoment anzupassen, welches durch das Eigengewicht der Türe erzeugt wird und vom Öffnungswinkel abhängt.The first leg of the bell crank is e.g. shorter than the second. This can reduce the burden of the door hinge (which is supported by the distance of the door lifter supported by the door lift Point of the door of the axis of the hinge is determined) can be reduced. Preferably the ratio of the effective lengths is about 2: 3. Of course you can the leverage ratios are varied to the power transfer to the variable torque adapted, which is generated by the weight of the door and the Opening angle depends.

Von Vorteil ist es, wenn der Kniehebelmechanismus und die Druckfeder in einem schmalen, rechteckigen Flachrahmen untergebracht sind. Dieser Rahmen wird z.B. durch zwei gestanzte Bleche gebildet, welche durch kurze Abstandselemente miteinander verbunden sind. Vorzugsweise ist der Rahmen symmetrisch ausgestaltet. Die Türheber-Vorrichtung ist dann seitenunabhängig, d.h. sie kann wahlweise links oder rechts der Türe montiert werden.It is advantageous if the toggle mechanism and the compression spring in a narrow, rectangular flat frame are housed. This frame is e.g. divided by two stamped sheets formed, which are interconnected by short spacers are. Preferably, the frame is symmetrical. The door lift device is then independent of page, i. It can be mounted either left or right of the door.

Selbstverständlich können die beweglichen Teile des Mechanismus auch an einem einseitig offenen Rahmen oder unmittelbar an einem Wandelement angebracht sein. Die Vorrichtung braucht nicht vollständig symmetrisch konstruiert zu sein. Vorzugsweise ist der Aufbau aber so gewählt, dass sie zumindest in funktioneller Hinsicht seitenunabhänig ist.Of course, the moving parts of the mechanism can also be on one side open frame or directly attached to a wall element. The device does not need to be completely symmetrical in design. Preferably, the structure is but chosen so that it is at least functionally independent of pages.

Im Hinblick auf eine sichere und ungestörte Funktion des Türhebers sollte die Druckfeder stets innerhalb des Rahmens sein, damit sie nicht während der Öffnungs- bzw. Schliessbewegung durch zufällig in die Nähe gelangende Gegenstände behindert oder blockiert werden kann. Nur der Betätigungsarm, welcher die Türe kontaktiert, soll aus dem Flachrahmen herausragen.With regard to a safe and undisturbed function of the door lifter, the compression spring should always be within the frame so that it does not move during the opening or closing movement obstructed or blocked by randomly approaching objects can be. Only the actuator arm, which contacts the door, should from the Protruding flat frame.

Gemäss einer besonders bevorzugten Ausführungsform geht der Kniehebel kurz vor Erreichen der Schliessstellung über den Totpunkt hinaus. Damit das Kniegelenk des Kniehebels bei geschlossener Türe, d.h. im Bereich jenseits des Totpunktes, eine definierte Position einnimmt und nicht unkontrolliert durchknickt, kann ein Anschlagelement vorgesehen sein. Dabei kann es sich z.B. um ein Kunststoffelement handeln, das an geeigneter Stelle im Flachrahmen integriert ist.According to a particularly preferred embodiment, the knee lever is about to be reached the closing position beyond the dead center. So that the knee joint of the toggle lever with the door closed, i. in the area beyond the dead center, a defined position occupies and not uncontrollably kinked, a stop element may be provided. This may be e.g. to act on a plastic element that is in place in the Flat frame is integrated.

Auch im geöffneten Zustand sollte eine Arretierung dafür sorgen, dass die Türe eine definierte Position einnimmt. Diese Arretierung ist vorzugsweise ebenfalls am Rahmen des Türhebers ausgebildet und greift beispielsweise am zweiten Schenkel des Kniehebels an. Eine andere Möglichkeit besteht z.B. darin, bei der Schraubenfeder eine Hubbegrenzung vorzusehen.Even when open, a lock should ensure that the door has a defined Takes position. This locking is preferably also on the frame of the Door lifter and engages, for example, on the second leg of the toggle lever. Another possibility is e.g. therein, in the coil spring, a stroke limitation provided.

Der erfindungsgemässe Türheber eignet sich namentlich für Schrankelemente, welche an erhöhter Stelle plaziert sind. Die Türe ist z.B. an einem separaten Schwenklager aufgehängt und wird vom Türheber geöffnet. Die Schwenkachse der Türe wird dann im Normalfall nicht mit dem Drehpunkt des auf die Türe drückenden Hebels zusammenfallen, sondern eine gewisse Exzentrizität gegenüber dem Hebeldrehpunkt haben. Damit diese Exzentrizität die Öffnungs- und Schliessbewegung nicht behindert, kann z.B. ein Gleitkontakt zwischen Türheber und Türe vorgesehen sein.The inventive door lifter is particularly suitable for cabinet elements, which on elevated place are placed. The door is e.g. suspended on a separate pivot bearing and is opened by the door lifter. The pivot axis of the door is then normally not coincide with the fulcrum of the lever pushing on the door, but have a certain eccentricity relative to the fulcrum. So this eccentricity does not hinder the opening and closing movement, e.g. a sliding contact be provided between door lift and door.

Gemäss einer besonders bevorzugten Ausführungsform ist der Türheber (und damit der Drehpunkt des fraglichen Betätigungshebels) ortsfest, die Schwenkachse der Türe dagegen verschiebbar. Beim Öffnen wird das Lager der Türe im erforderlichen Ausmass verschoben. Das Schwenklager der Türe ist auf einem horizontal verschiebbaren Schlitten gelagert, so dass die ganze Türe nach dem Öffnen im Schrankelement (bzw. einem entsprechend vorgesehenen Schacht) versenkt werden kann. According to a particularly preferred embodiment, the door lifter (and thus the Fulcrum of the operating lever in question) stationary, the pivot axis of the door, however displaceable. When opening the bearing of the door is moved to the required extent. The pivot bearing of the door is on a horizontally movable carriage stored so that the whole door after opening in the cabinet element (or a corresponding provided shaft) can be sunk.

Die versenkbare Türe weist z.B. ein Kupplungsstück auf, in welches ein entsprechendes Stück des Betätigungshebels während der Öffnungs- und Schliessbewegung eingreifen kann. Die Kupplung ist so gestaltet, dass sich die Stücke beim Versenken der Türe ohne Kraftaufwand voneinander lösen. Die Kopplung zwischen Türheber und Türe ermöglicht es, die Türe beim Schliessen in die gewünschte Schliessstellung zu ziehen. D.h. es kann nicht nur Druck, sondern auch Zug übertragen werden.The retractable door has e.g. a coupling piece, in which a corresponding Engage piece of the operating lever during the opening and closing movement can. The coupling is designed so that the pieces when sinking the door without Solve effort from each other. The coupling between the door lift and the door makes it possible to pull the door when closing in the desired closed position. That it can not only pressure, but also train to be transferred.

Das am Türheber ausgebildete Kupplungsstück bietet dem Kupplungsstück der Türe vorzugsweise einen Anschlag, so dass die Türe beim Öffnen kurz vor Erreichen der horizontal vorstehenden Position zwangsläufig um ein gewisses Mass in das Schrankelement zurückgezogen wird. In dieser leicht versenkten Stellung ist die Türe gegen ein unerwünschtes Überdrehen besser gesichert (''Crashschutz'').The trained on the door lifter coupling piece provides the coupling piece of the door preferably a stop so that the door when opening just before reaching the horizontal protruding position necessarily retracted by a certain amount in the cabinet element becomes. In this slightly lowered position, the door is against an undesirable Overspeeding better secured ('' crash protection '').

Wege zur Ausführung der ErfindungWays to carry out the invention

In der Fig. 1 ist eine besonders bevorzugte Ausführungsform der Erfindung gezeigt. Die beweglichen Teile sind in einem Rahmen untergebracht, welcher im wesentlichen durch zwei Seitenteile 1, 2 gebildet ist. In Fig. 1 ist nur der Seitenteil 1 dargestellt. Der zweite (welcher in Fig. 2b erkennbar ist) wurde weggelassen, um den Kniehebelmechanismus sichtbar zu machen.In Fig. 1, a particularly preferred embodiment of the invention is shown. The moving parts are housed in a frame, which essentially by two side parts 1, 2 is formed. In Fig. 1, only the side part 1 is shown. The second (which can be seen in Fig. 2b) has been omitted to the toggle mechanism to make visible.

Die Seitenteile 1, 2 sind identisch ausgestaltet. Es handelt sich um langgezogene, rechteckige, flache Stahlblechelemente, welche in den für die Stabilität nicht relevanten Bereichen ausgenommen (z.B. ausgestanzt) sind. Die Höhe beträgt z.B. nur etwa 1/5 bis 1/6 der Länge.The side parts 1, 2 are configured identically. It is elongated, rectangular, flat sheet steel elements, which are not relevant in the areas of stability excluded (e.g., stamped out). The height is e.g. only about 1/5 to 1/6 the length.

Am vorderen Ende des Rahmens (in Fig. 1 in der vorderen oberen Ecke) ist eine Achse 4 angeordnet, welche einerseits die beiden Seitenteile 1, 2 in einem gewünschten Abstand miteinander verbindet und andererseits einen L-förmigen Betätigungshebel 3 drehbar lagert. In der offenen Stellung des Türhebers (d.h. bei geöffneter, horizontal vorstehender Türe) ragt der lange Schenkel 3.1 des Betätigungshebels 3 in einer Verlängerung der oberen Kante des Rahmens (Seitenteile 1, 2) horizontal nach vorn. An seinem Ende ist ein Kupplungsstück 20 angebracht. Der kurze Schenkel 3.2 schliesst mit dem langen einen Winkel von etwas weniger als 90° ein. Er ragt in der offenen Stellung gemäss Fig. 1 nach unten. Seine Länge entspricht etwa der Höhe des Rahmens.At the front end of the frame (in Fig. 1 in the front upper corner) is an axis 4th arranged, on the one hand, the two side parts 1, 2 at a desired distance connects to each other and on the other hand rotatably supports an L-shaped operating lever 3. In the open position of the door lifter (i.e., open, horizontally protruding Door) projects the long leg 3.1 of the actuating lever 3 in an extension of the upper Edge of the frame (side panels 1, 2) horizontally forward. At its end is one Coupling piece 20 attached. The short leg 3.2 closes with the long one Angle of slightly less than 90 °. It protrudes in the open position according to FIG. 1 below. Its length corresponds approximately to the height of the frame.

Am Ende des kurzen Schenkels 3.2 sind mit einer Achse 6 zwei streifenförmige Flachelemente 5.1, 5.2 mit ihrem ersten Ende angelenkt. An den anderen Enden sind die Flachelemente 5.1, 5.2 mit Hilfe einer weiteren Achse 7 an einem abgewinkelten Arm 9 eines Führungshebels 8 angelenkt. Der L-förmige Führungshebel 8 ist am Ende seines langen Schenkels in der Achse 10 schwenkbar an den Seitenteilen 1, 2 gelagert.At the end of the short leg 3.2 are with an axis 6 two strip-shaped flat elements 5.1, 5.2 articulated with its first end. At the other ends are the Flat elements 5.1, 5.2 by means of another axis 7 on an angled arm. 9 a guide lever 8 hinged. The L-shaped guide lever 8 is at the end of its long Leg in the axis 10 pivotally mounted on the side parts 1, 2.

Im Knie des L-förmigen Führungshebels 8 greift ein Gabelkopf 13 einer Stange 12 an. Die Verbindung zwischen Gabelkopf 13 und Führungshebel 8 ist gelenkig ausgebildet (Achse 11). Die Stange 12 ist mit ihrem hinteren Ende in einem Rohr 14 verschiebbar gelagert. Das Rohr 14 selbst ist schwenkbar auf der Achse 15 angebracht. Auf der Stange 12 befindet sich eine Schraubenfeder 21, welche den Gabelkopf 13 (und damit die Stange 12) nach vorne, d.h. aus dem Rohr 14 heraus drückt.In the knee of the L-shaped guide lever 8 engages a clevis 13 of a rod 12 at. The Connection between clevis 13 and guide lever 8 is articulated (axis 11). The rod 12 is slidably mounted with its rear end in a tube 14. The tube 14 itself is pivotally mounted on the axle 15. Located on the pole 12 a coil spring 21, which the clevis 13 (and thus the rod 12) forward, i. out of the tube 14 pushes.

Zwischen den Achsen 4 und 10 erstrecken sich zwei Anschlagelemente 16.1, 16.2. Es kann sich z.B. um streifenförmige Teile aus Kunststoff handeln.Between the axes 4 and 10, two stop elements 16.1, 16.2 extend. It can be e.g. to act strip-shaped parts made of plastic.

Weitere Anschlagelemente sind an den Flachelementen 5.1, 5.2 ausgebildet. In Fig. 1 ist ein Nocken 17 eingezeichnet, welcher in einer noch zu beschreibenden Weise als Anschlagelement dient. Ein zweiter, gleichartiger Nocken ist am Flachelement 5.2 angeformt. Die genannten Anschlagelemente sind an den Aussenseiten der Flachelemente 5.1, 5.2 (d.h. an den Flächen, welche den Seitenteilen 1, 2 der Flachelemente zugewandt sind) vorgesehen. An den Innenseiten der Seitenteile 1, 2 sind an entsprechender Stelle korrespondierende Anschlagelemente (nicht dargestellt) angeordnet. In der geöffneten Stellung des Türhebers sorgen die genannten Anschlagelemente dafür, dass der Betätigungshebel 3 eine definierte Stellung einnimmt.Further stop elements are formed on the flat elements 5.1, 5.2. In Fig. 1 is a cam 17 located, which in a manner to be described as a stop element serves. A second, similar cam is formed on the flat element 5.2. The aforementioned stop elements are on the outer sides of the flat elements 5.1, 5.2 (i.e., on the surfaces facing the side parts 1, 2 of the flat elements). On the inner sides of the side parts 1, 2 are corresponding at corresponding location Stop elements (not shown) arranged. In the open position of the Door lifters ensure that the stop elements mentioned that the operating lever. 3 occupies a defined position.

Die beiden Seitenteile 1, 2 sind nicht nur durch die Achsen 4, 10, 15, sondern auch durch die Abstandshalter 18, 19 miteinander verbunden. Es besteht somit zumindest in drei Ecken des Rahmens eine Verbindung zwischen den Seitenteilen 1, 2.The two side parts 1, 2 are not only by the axes 4, 10, 15, but also by the spacers 18, 19 connected to each other. It therefore exists at least in three Corners of the frame a connection between the side parts 1, 2.

Aus Fig. 2b ist deutlich die Symmetrie der erfindungsgemässen Konstruktion bezüglich der Rahmenmittelebene (d.h. der parallel zu den flächenhaften Seitenteilen 1, 2 und in der Mitte zu diesen stehenden geometrischen Ebene) zu erkennen. Der gegenseitige Abstand der Seitenteile 1, 2 ist so klein wie möglich gewählt. Gemäss Fig. 2b entspricht der genannte Abstand der Summe der Dicke der folgenden Elemente: Betätigungshebel 3, Flachelemente 5.1 und 5.2, Anschlagelemente 16.1 und 15.2.From Fig. 2b is clearly the symmetry of the inventive construction with respect to Frame center plane (i.e., parallel to the planar side parts 1, 2 and in the Center to this standing geometric plane). The mutual distance the side parts 1, 2 is chosen as small as possible. According to Fig. 2b corresponds to the mentioned Distance of the sum of the thickness of the following elements: operating lever 3, Flat elements 5.1 and 5.2, stop elements 16.1 and 15.2.

In den Figuren 3a und 3b ist der Türheber gemäss Fig. 1 dargestellt, wie er beispielhaft in einem Schrankelement montiert ist. Der vordere Seitenteil 2 ist wiederum weggelassen, um den Blick auf den Kniehebelmechanismus freizugeben. In Figures 3a and 3b, the door lifter is shown in FIG. 1, as exemplified in a cabinet element is mounted. The front side part 2 is again omitted, to release the view of the toggle mechanism.

Eine Türe 22 ist an einem Scharnier 23 mit horizontal verlaufender Drehachse aufgehängt. In der Darstellung gemäss Fig. 3a, b steht die Drehachse senkrecht zur Zeichenebene. Die Türe 22 kann von einer vertikal hängenden (Fig. 3b) in eine horizontal vorstehende (Fig. 3a) Stellung geschwenkt werden. Im vorliegenden Beispiel ist die plattenförmige Türe 22 an der oberen Kante 22.1 mit dem Scharnier 23 verbunden.A door 22 is suspended on a hinge 23 with a horizontal axis of rotation. In the illustration according to FIG. 3a, b, the axis of rotation is perpendicular to the plane of the drawing. The Door 22 may extend from a vertically suspended (Figure 3b) to a horizontally projecting (Figure 3a). Be pivoted position. In the present example, the plate-shaped door 22 is on the upper edge 22.1 connected to the hinge 23.

Das Scharnier 23 sitzt auf einem Schlitten 24, welcher in Richtung des Pfeiles 29 auf einer Schiene 25 nach hinten in das Schrankelement hinein verschoben werden kann. Die Schiene 25 ist an einem Seitenträger 28 ausgebildet, welcher zugleich zur Befestigung des Türhebers 30 dient. In Fig. 3a, b ist noch andeutungsweise ein Rahmenrohr 27 gezeigt, welches Teil des Schrankelementes ist und welches den oberen Rand der Schranköffnung bildet. (Weitere, nicht dargestellte Rahmenrohre begrenzen die genannte Öffnung an den drei übrigen Rändern.)The hinge 23 is seated on a carriage 24, which in the direction of arrow 29 on a Rail 25 can be moved back into the cabinet element into it. The Rail 25 is formed on a side support 28, which at the same time for fixing the Door lifter 30 is used. In Fig. 3a, b is hinted a frame tube 27 shown which is part of the cabinet element and which is the upper edge of the cabinet opening forms. (Other, not shown frame tubes limit said opening to the three remaining edges.)

An der Innenseite der Türe 22 ist ein Kupplungsstück 26 angebracht, welches in das Kupplungsstück 20 des Türhebers eingreifen kann.On the inside of the door 22, a coupling piece 26 is mounted, which in the Coupling piece 20 of the door lifter can intervene.

Im folgenden soll die Funktionsweise des Türhebers 30 erläutert werden.In the following, the operation of the door lifter 30 will be explained.

In der offenen Stellung gemäss Fig. 3a kann die Türe 22 in Richtung des Pfeiles 29 im Schrankelement (d.h. im Zwischenraum zwischen der Schiene 25 und dem sich parallel zur Schiene 25 nach hinten erstreckenden Türheber 30) versenkt werden. Beim Versenken lösen sich die Kupplungsstücke 20 und 26 voneinander. Die Türe 22 wird vom Türheber gestützt und gleitet dabei mit ihrer Innenseite auf dem Kupplungsstück 20. Die Gleitreibung ist ziemlich klein, so dass die Türe 22 ohne besonderen Kraftaufwand versenkt werden kann.In the open position according to Fig. 3a, the door 22 in the direction of arrow 29 in Cabinet element (i.e., in the space between the rail 25 and the parallel to the Rail 25 rearwardly extending door lifter 30) are sunk. When sinking Loosen the coupling pieces 20 and 26 from each other. The door 22 is from the door lift supported and slides with its inside on the coupling piece 20. The sliding friction is quite small, so that the door 22 are sunk without any special effort can.

In der horizontalen Stellung gemäss Fig. 3a wird die Türe 22 durch den Betätigungshebel 3 gehalten, welcher durch die Schraubenfeder 21 in die offene Stellung gedrückt wird. Die Stange 12 und die Flachelemente 5.1, 5.2 (in Fig. 3a, b ist nur das Flachelement 5.1 dargestellt) befinden sich dabei auf einer geraden Linie. Diese Linie ist parallel zu einer gedachten Verbindungslinie zwischen den Achsen 4 und 10. Der Kniehebel, welcher durch die Flachelemente 5.1, 5.2 einerseits und durch den Schenkel 3.2 andererseits gebildet ist, befindet sich in einer Stellung maximaler Kraftübertragung.In the horizontal position according to FIG. 3 a, the door 22 is moved by the actuating lever 3 held, which is pressed by the coil spring 21 in the open position. The Bar 12 and the flat elements 5.1, 5.2 (in Fig. 3a, b is only the flat element 5.1 shown) are located on a straight line. This line is parallel to one imaginary connecting line between the axes 4 and 10. The toggle, which by formed the flat elements 5.1, 5.2 on the one hand and by the leg 3.2 on the other is in a position of maximum power transmission.

Zum Schliessen der Türe 22 wird sie vom Benutzer nach unten gedrückt, wobei sie um das Scharnier 23 in Richtung des Pfeiles 31 schwenkt. Die vom Benutzer erzwungene Bewegung dreht den Betätigungshebel 3 um die Achse 4. Entsprechend werden die Flachelemente 5.1, 5.2 und die Stange 12 zunächst in Richtung ihrer Längsachse nach hinten gedrückt. Die Schraubenfeder 21, welche das Eigengewicht der Türe 22 hält, wird folglich komprimiert.To close the door 22, it is pressed down by the user, where they are around the Hinge 23 pivots in the direction of arrow 31. The movement forced by the user rotates the operating lever 3 about the axis 4. Accordingly, the flat elements 5.1, 5.2 and the rod 12 initially in the direction of its longitudinal axis to the rear pressed. The coil spring 21, which holds the dead weight of the door 22, is consequently compressed.

Mit abnehmendem Öffnungswinkel wird das Kraftübertragungsverhältnis des Kniehebels geringer. Obwohl also die Schraubenfeder 21 beim Komprimieren den Druck erhöht, nimmt insgesamt die vom Betätigungshebel 3 auf die Türe 22 angewendete Kraft ab. Diese Abnahme der Kraft korrespondiert mit dem Drehmoment, welches durch das Eigengewicht der Türe 22 (auf die Achse des Scharniers 23 bezogen) erzeugt wird und welches mit abnehmendem Öffnungswinkel geringer wird. Der Benutzer hat infolgedessen das Gefühl, dass die Türe 22 ausbalanciert ist. Je nach Bedarf können die Hebelverhältnisse im Türheber so gewählt werden, dass die Türe die Tendenz hat, sich in die offene oder in die geschlossene Stellung zu bewegen.With decreasing opening angle, the power transmission ratio of the toggle lever lower. Thus, although the coil spring 21 increases the pressure during compression, takes a total of the force applied by the operating lever 3 on the door 22 force. These Decrease in force corresponds to the torque, which is due to its own weight the door 22 (based on the axis of the hinge 23) is generated and which with decreasing Opening angle is lower. As a result, the user has the feeling that the door 22 is balanced. Depending on requirements, the lever ratios in the door lifter be chosen so that the door has a tendency to open or closed To move position.

Fig. 3b zeigt die geschlossene Stellung. Das Kniegelenk (vgl. Achse 6) des Kniehebels (oder genau genommen die Flachelemente 5.1, 5.2) liegt (bzw. liegen) an den Anschlagelementen 16.1, 16.2 an. Das Gelenk befindet sich jenseits des Totpunktes, was zur Folge hat, dass der Druck der Schraubenfeder 21 die Türe nicht mehr nach aussen drückt, sondern nach innen in die Schliessstellung zieht. In diesem Zusammenhang ist zu beachten, dass das Zuziehen der Türe 22 durch die Kupplungsstücke 20 und 26 ermöglicht wird. Diese sind nämlich so ausgebildet, dass Türe 22 und Betätigungshebel 3 während der Schwenkbewegung fest gekoppelt bleiben.Fig. 3b shows the closed position. The knee joint (cf axis 6) of the toggle lever (or, strictly speaking, the flat elements 5.1, 5.2) is (or are) on the stop elements 16.1, 16.2. The joint is beyond the dead center, resulting in has that the pressure of the coil spring 21 no longer pushes the door to the outside, but moves inwards into the closed position. In this context is too Note that the closing of the door 22 by the coupling pieces 20 and 26 allows becomes. These are in fact designed so that door 22 and operating lever 3 during the Swivel movement remain firmly coupled.

Der Totpunkt wird z.B. bei einem Öffnungswinkel von 5° bis 10° durchschritten, d.h. bei einem Winkel, bei welchem das durch das Eigengewicht der Türe bedingte Drehmoment relativ klein ist. Allerdings ist zu beachten, dass im Totpunkt die Türe bereits ein minimales Drehmoment auf den Hebelmechanismus ausübt und die beginnende Kraftentwicklung der Feder dadurch bremst.The dead point is e.g. passed through at an opening angle of 5 ° to 10 °, i. at an angle at which the conditional by the weight of the door torque is relatively small. However, it should be noted that at dead center the door is already a minimal Torque exerts on the lever mechanism and the incipient force development of the Spring thereby brakes.

Wie aus Fig. 3b zu erkennen ist, liegen die Flachelemente 5.1, 5.2 bei geschlossenem Türheber im wesentlichen parallel zum Führungshebel 8. Die Stange 12 und der Führungshebel 8 schliessen einen Winkel nahe bei 180° ein. Eine gedachte Verlängerung der Stange 12 geht im wesentlichen durch die Achse 4. Die Achse 10 liegt also geringfügig oberhalb einer gedachten Verbindungslinie zwischen Achse 11 und Achse 4. Betrachtet man das durch die Achsen 4, 7 und 6 gebildete Dreieck und vergleicht es mit dem durch die Achsen 10, 11 und 15 gebildeten Dreieck, dann stellt man fest, dass diese aufeinander zu gerichtet sind. Mit anderen Worten: Beim Dreieck 4/7/6 befindet sich die der Grundseite 4/7 gegenüberliegenden Ecke (6) auf der dem Dreieck 10/11/15 zugewandten Seite. In sinngemässer Weise befindet sich beim Dreieck 10/11/15 die der Grundseite 10/15 gegenüberliegende Ecke (11) auf der dem Dreieck 4/7/6 zugewandten Seite.As can be seen from FIG. 3b, the flat elements 5.1, 5.2 lie with the door lifter closed substantially parallel to the guide lever 8. The rod 12 and the guide lever 8 enclose an angle close to 180 °. An imaginary extension of the rod 12 passes essentially through the axis 4. The axis 10 is thus slightly above an imaginary connecting line between axis 11 and axis 4. Looking at this formed by the axes 4, 7 and 6 triangle and compares it with that through the axes 10, 11 and 15 formed triangle, then it is found that these are directed towards each other are. In other words: In triangle 4/7/6, the base is 4/7 opposite corner (6) on the triangle 10/11/15 facing side. In analogous Way is located at the triangle 10/11/15 of the base 10/15 opposite Corner (11) on the side facing the triangle 4/7/6.

Der Vorteil dieser Konstruktion besteht darin, dass keine separate Vorrichtung vorgesehen werden muss, welche die Türe (gegen die Kraft des Türhebers) in der geschlossenen Stellung hält.The advantage of this construction is that no separate device is provided must be, which the door (against the power of the door lifter) in the closed position holds.

Aus Fig. 3a ist ferner erkennbar, dass die Länge der Flachelemente 5.1, 5.2 (bzw. der Abstand zwischen den Achsen 6, 7) geringfügig (z.B. ca. 10%) kleiner ist als der gegenseitige Abstand der Achsen 4 und 10. Zudem ist der Abstand der Achsen 6 und 11 in der offenen Stellung des Türhebers geringfügig (z.B. ca. 10%) grösser als der gegenseitige Abstand der Achsen 4 und 10.From Fig. 3a is further seen that the length of the flat elements 5.1, 5.2 (or the distance between the axes 6, 7) is slightly smaller (e.g., about 10%) smaller than the mutual one Distance of the axes 4 and 10. In addition, the distance between the axes 6 and 11 in the open Position of the door lift slightly (for example, about 10%) greater than the mutual distance of Axles 4 and 10.

Die Kupplungsstücke 20, 26 können z.B. nach dem Nut-Feder-Prinzip in Richtung des Pfeiles 29 (d.h. parallel zur Türe) ineinander geschoben werden.The coupling pieces 20, 26 may e.g. according to the tongue and groove principle in the direction of Arrows 29 (i.e., parallel to the door) are telescoped.

Eine weitere Besonderheit der dargestellten Ausführungsform besteht darin, dass die Türe 22 beim Erreichen der offenen Stellung bereits leicht versenkt ist. D.h. die Achse des Scharniers 23 ist bei offener Türe 22 nicht mehr am selben Ort wie bei geschlossener Türe 22. Vielmehr ist sie in Richtung des Pfeiles 29 nach hinten verschoben. Dies hat den Vorteil, dass das Scharnier 23 gegen Überdrehen gesichert ist (''Crashschutz''). Die Türe 22 steht nämlich am Rahmenrohr 27 an und kann infolgedessen nicht über die horizontale Stellung hinaus nach oben geschwenkt werden. Die resultierende Blockierung ist umso zuverlässiger, je weiter entfernt der Kontaktpunkt zwischen Türe 22 und Rahmenrohr 27 von der Achse des Scharniers 23 ist.Another special feature of the illustrated embodiment is that the door 22 is already slightly sunk when reaching the open position. That the axis of Hinge 23 is no longer at the same door with the door open 22 as when the door is closed 22. Rather, it is shifted in the direction of arrow 29 to the rear. This has the advantage that the hinge 23 is secured against over-rotation ('' crash protection ''). The door 22 in fact stands on the frame tube 27 and consequently can not on the horizontal Be pivoted position out to the top. The resulting blocking is all the more more reliable, the farther the contact point between door 22 and frame tube 27 from the axis of the hinge 23 is.

Das Zurückschieben der Türe 22 hängt damit zusammen, dass einerseits ein Abstand zwischen der Achse 4 des Betätigungshebels 3 und der Achse des Scharniers 23 besteht und dass andererseits die Kupplungsstücke 20, 26 so ausgebildet sind, dass sich die Türe 22 beim Schwenken nicht über eine Position hinaus verschieben kann, welche durch die Geometrie bei geschlossener Türe 22 bestimmt ist.The pushing back of the door 22 is related to the fact that on the one hand a distance between the axis 4 of the actuating lever 3 and the axis of the hinge 23 is and on the other hand that the coupling pieces 20, 26 are formed so that the door 22 when panning can not move beyond a position, which by the Geometry with the door closed 22 is determined.

Wie weit die Türe 22 aus der Versenkung herausgezogen werden kann, ist nicht durch die vordere Endposition des Schlittens 24 auf der Schiene 25 bestimmt, sondern durch das Kupplungsstück 20, in welches das Kupplungsstück 26 hineingeschoben wird. Erst wenn die Türe 22 um einen gewissen Winkel nach unten geschwenkt ist, befindet sich der Schlitten 24 am vorderen Anschlag (Endposition).How far the door 22 can be pulled out of the sink is not through the determined front end position of the carriage 24 on the rail 25, but by the Coupling piece 20, in which the coupling piece 26 is pushed. Only when the door 22 is pivoted downwards by a certain angle, is the carriage 24 at the front stop (end position).

Die Erfindung beschränkt sich natürlich nicht auf das beschriebene Ausführungsbeispiel. Im folgenden sollen kurz einige Variationsmöglichkeiten angedeutet werden.Of course, the invention is not limited to the embodiment described. In the following, a few variations are suggested.

Die Türe braucht keineswegs versenkbar zu sein. Es ist durchaus möglich, dass sie fest mit dem Betätigungshebel des Türhebers verbunden ist. Schwenkachse der Türe ist dann die Achse des Betätigungshebels. Es kann auch von einem ortsfesten, vom Türheber unabhängigen Scharnier ausgegangen werden, wobei dann die Kontaktstelle zwischen Betätigungshebel und Türe sich verschieben kann.The door does not need to be retractable. It is quite possible that she is stuck with is connected to the operating lever of the door lifter. Swivel axis of the door is then the Axle of the operating lever. It can also be a fixed, independent from the door lift Hinge are assumed, in which case the contact point between the operating lever and door can move.

Der Kniehebel kann so konstruiert sein, dass er sich in der geschlossenen Stellung gerade im Totpunkt befindet. Es ist aber auch keineswegs ausgeschlossen, dass der Totpunkt gar nicht erreicht wird. D.h. die Feder wird dann stets einen Öffnungsdruck auf die Türe ausüben können. Um die Türe trotzdem in der geschlossenen Stellung festhalten zu können, kann am Schrankelement ein rastender Verschluss vorgesehen sein. The toggle may be designed to be straight in the closed position located in the dead center. But it is by no means impossible that the dead center even is not achieved. That the spring will then always exert an opening pressure on the door can. To still be able to hold the door in the closed position, can be provided on the cabinet element a latching closure.

Die Wahl der Hebelverhältnisse wird im Einzelfall auf das Gewicht der Türe und die geometrischen Vorgaben abzustimmen sein.The choice of leverage is in the individual case on the weight of the door and the geometric Be agreed specifications.

Das Ausführungsbeispiel zeigt eine Konstruktion, die sich durch eine geringe Bauhöhe auszeichnet. Für andere Anwendungen kann es u.U. erwünscht sein, einen Türheber mit möglichst geringer Einbautiefe zu haben. Es ist leicht erkennbar, dass die gezeigte Konstruktion quasi um 90° in die Vertikale gedreht werden kann, wobei dann z.B. der Betätigungshebel anders ausgeführt sein muss. Anstelle eines L-förmigen Hebels könnte ein einarmiger Hebel vorgesehen sein (d.h. der Schenkel 3.2 dient gleichzeitig als Kontaktelement zur Türe).The embodiment shows a construction which is characterized by a low height. For other applications it may u.U. be desired to use a door lift as possible to have a small installation depth. It is easy to see that the construction shown can be rotated approximately 90 ° in the vertical, then the operating lever must be executed differently. Instead of an L-shaped lever could be a one-armed Lever be provided (i.e., the leg 3.2 also serves as a contact element for Door).

Die Schwenkachse der Türe muss nicht zwingend am oberen Rand des Türblattes vorgesehen sein. Die Türe kann ohne weiteres nach oben überstehend montiert sein.The pivot axis of the door does not necessarily have to be provided at the upper edge of the door leaf be. The door can easily be mounted upwardly projecting.

Die Erfindung kann überall dort eingesetzt werden, wo es darum geht, eine Türe aus einer vertikal hängenden Stellung in eine mehr oder weniger horizontal vorstehende zu bringen.The invention can be used wherever it comes, a door from a bring vertical hanging position in a more or less horizontally protruding.

Zusammenfassend ist festzustellen, dass der erfindungsgemässe Türheber aus robusten und langlebigen Elementen aufgebaut ist und sich wegen seiner kompakten Konstruktion namentlich für Schrankelemente mit Einbauten (Schienen für Auszugsschubladen, Zwischenregalen etc.) eignet.In summary, it should be noted that the inventive door lifter made of robust and durable elements and is built because of its compact design namely for cabinet elements with fittings (rails for pull-out drawers, intermediate shelves etc.) is suitable.
