Definitions
- the present invention relates to a locking device with a handle, a locking and opening mechanism comprising at least one locking element, the at least one locking element being movable from an open position into a closed position with the aid of a locking pressure spring, the locking pressure spring to support the closing movement of the at least one locking element has a first bias.
- Such a locking device is z. B. off EP 1 617 018 A2 , EP 2 677 098 A1 , DE 197 07 762 C1 , EP 1 688 566 C1 and DE 37 00 891 A1 known.
- a locking element is already biased on the way from a closed position to an open position.
- a locking device is to be used in conjunction with keyless locking systems in which a locking process is automatically triggered, for example if a door "falls into a lock" or a door leaf is guided by a handle or knob with its faceplate opposite a strike plate in the door frame is aligned. During this alignment process, the release is then generally dependent on a spring force that has to be overcome in order to sufficiently pre-tension a locking element before it is released.
- the locking element is usually pretensioned with a locking pressure spring.
- Such locking devices of the prior art are used equally with only one locking element as well as with several locking elements and with a multiple lock. If a high pre-tensioning of the control element is required to reliably reach the closed position, this high pre-tensioning can no longer only be achieved by "falling into the lock" of a door or the like. The force required to pretension the locking spring would be too great for this, so that the components subjected to a corresponding spring force are not only caused by an acoustically perceptible "beating" the door can be moved against the spring force but can also damage other components, such as a door frame.
- the object of the present invention is therefore to create a locking device of the type mentioned at the outset with which, during a locking process, a high pretensioning of a locking element can also be achieved without the disadvantages mentioned above.
- the object is achieved according to the invention in that the locking pressure spring in the open position is free of prestress in one state and has the first prestress in another state after the lever has been turned.
- a locking pressure spring to support the closing movement of at least one locking element by manual force transmission, i.e. by rotating the printer.
- the spring force required to initiate a closing process can be kept so low that a door or the like can continue to fall gently into a lock to initiate the closing process or to trigger the closing movement of the at least one locking element into its closed position.
- a further advantage of the present invention is that the pusher is connected to the bolt compression spring via a tensioning lever and the tensioning lever builds up the bias of the bolt compression spring when the pusher is turned.
- a tensioning lever has proven to be a structurally favorable component in order to transfer the force generated by the rotation of the printer to the bolt compression spring.
- tensioning lever can be locked when it reaches a position which corresponds to the first pretensioning of the bolt compression spring.
- the latch compression spring is preloaded to a predetermined first preload by means of a rotary movement of the handle, and this first preload is preserved until it is required for a closing process.
- Another advantage of the present invention is that the clamping lever is locked by a latching lever arranged below the at least one locking element.
- a release plate for triggering the closing movement of the at least one locking element has a second preload which is less than the first preload of the at least one locking element.
- the release plate is provided on a faceplate and protrudes in the direction of the strike plate of a door frame. When a door is closed, that is, when the door "falls into the lock", the release plate is pushed back into the locking device against the direction of action of the second preload until the clamping lever is released from its locking position via the locking and opening mechanism. Since this second preload is much lower than the first preload, no great force is required for pure release. In any case, this force is much smaller than the spring force of the latch compression spring.
- the closing and opening mechanism comprises a multiple lock with a plurality of locking elements. Due to the separation between the necessary triggering force to trigger a closing movement of the at least one locking element and the necessary closing force to carry out the closing movement of the at least one locking element, with the present invention not only several locking elements in one and the same locking device but also several control elements of a so-called multiple lock can be reliably Closing force can be moved into the closed position. The release force required for this always remains the same, ie low.
- a locking device 1 is shown schematically in a side view in a first embodiment.
- the locking device 1 comprises a lock housing 3 and a faceplate 5.
- a locking and opening mechanism 7 is arranged in the lock housing 3.
- the closing and opening mechanism 7 comprises, among other things, in the present embodiment a locking element 9, a latch element 11, a release plate 13 and a nut 15 on which a handle 17 engages.
- the follower 15 is structurally connected to the locking element 9 and to the latch element 11 via various lever-like components, so that actuation of the trigger 17, i.e. turning the trigger 17 clockwise, causes the latch element 11 to retract into the lock housing 3. Due to a bias of the latch element 11, this is in the open position of the locking device in the Figure 1 position shown.
- the closing and opening mechanism 7 essentially comprises four pretensioning elements.
- the first biasing element is a bolt compression spring 19
- the second biasing element is a return spring 21
- the third biasing element is a release plate spring 23
- the fourth biasing element is a latching lever spring 25. Further biasing elements are conceivable.
- the pusher 17 is in a substantially horizontal position.
- the latch compression spring 19 is not tensioned.
- the return spring 21 and the latching lever spring 25 are also not tensioned.
- Only the release plate 13 is tensioned by the release plate spring 23 and is located together with the latch element 11 in a position protruding from the faceplate 5. In this position, for example, a door (not shown) is open.
- FIG 2 is shown how the handle 17 is a little clockwise before closing the door is rotated.
- the pusher 17 is out of its essentially horizontal orientation by 11.5 ° compared to the position in FIG Figure 1 twisted.
- the locking pressure spring 19 is tensioned.
- the nut 15, with which the handle 17 is connected engages a tensioning lever 27, which with a free end 27.1 compresses the bolt compression spring 19 until the free end 27.1 of the tensioning lever 27 engages in a latching lever 29 and this presses a little downwards against the spring force of the locking lever spring 25.
- the locking lever is locked in this position.
- a door with the locking device 1 according to the invention can be in the in Figure 3 situation depicted are closed.
- FIG 5 the locking device 1 according to the invention is shown in its closed position with the door closed.
- the door leaf has been pivoted and the faceplate 5 has been brought into alignment with a strike plate 31, which is located on a door frame (not shown), and is now opposite the strike plate 31.
- the release plate 13 was in the way, so that it was pressed into the lock housing 3 during this process against the force of the release plate spring 23 (second preload) (see arrow).
- the release plate 23 has released the locking of the latching lever 29, so that the at least one locking element 9 was moved into the closed position (see arrow) under the action of the strong spring force (first preload) of the locking pressure spring 19.
- first preload of the bolt compression spring 19
- the first preload of the bolt compression spring 19 can thus be selected to be considerably greater than the second preload of the release plate spring 23.
- FIG. 5 In addition to the first embodiment with only one locking element 9, a second embodiment with an integrated multi-point lock 33 is also shown.
- the multi-point lock 33 has a construction known per se and is therefore not described further here.
- the multi-point lock 33 is connected to the closing and opening mechanism 7 in a manner which is also known per se via an unlocking device 35.
- the above-described closing movement with the aid of the large first bias of the bolt compression spring 19 and the lower second bias of the release plate spring 23 is transmitted via the closing and opening mechanism 7 to the multiple lock 33 and its bolt (not shown).
- the closing and opening mechanism 7 tensions the return spring 21, which pulls the at least one locking element 9 back into the lock housing 3 during an opening process.
- FIG. 6 is shown schematically how the in Figure 5
- the situation shown changes when the door is closed, ie the latch element 11 and the release plate 13 in FIG the corresponding recesses engage in the strike plate 31, but the at least one locking element 9 is withdrawn so that the door can be opened by means of the handle 17. If the handle 17 is turned a little clockwise downwards according to the arrow, the unlocker 35 unlocks, so that the bolts of the multi-point lock 33 are also withdrawn.
- the tensioning lever 27 is located with its free end 27.1 out of engagement with the locking lever 29. Basically, the one in FIG Figure 1 presented situation.

Description
Die vorliegende Erfindung betrifft eine Schließvorrichtung mit einem Drücker, einer Schließ-und Öffnungsmechanik, die wenigstens ein Riegelelement umfasst, wobei das wenigstens eine Riegelelement mithilfe einer Riegeldruckfeder aus einer Öffnungsstellung in eine Schließstellung bewegbar ist, wobei die Riegeldruckfeder zur Unterstützung der Schließbewegung des wenigstens einen Riegelelements eine erste Vorspannung hat.The present invention relates to a locking device with a handle, a locking and opening mechanism comprising at least one locking element, the at least one locking element being movable from an open position into a closed position with the aid of a locking pressure spring, the locking pressure spring to support the closing movement of the at least one locking element has a first bias.
Eine solche Schließvorrichtung ist z. B. aus
Solche Schließvorrichtungen des Standes der Technik werden gleichermaßen mit nur einem Riegelelement wie auch mit mehreren Riegelelementen und mit einer Mehrfachverriegelung verwendet. Wenn für ein sicheres Erreichen der Schließstellung eine hohe Vorspannung des Regelelements erforderlich ist, kann er diese hohe Vorspannung nicht mehr nur durch ein "ins Schloss Fallen" einer Tür oder dergleichen erreicht werden. Die für das Vorspannen der Riegeldruckfeder benötigte Kraft wäre dafür zu groß, so dass die mit einer entsprechenden Federkraft beaufschlagten Bauteile nicht nur durch ein akustisch wahrnehmbares "Schlagen" der Tür entgegen der Federkraft bewegbar sind sondern auch dabei andere Bauteile, wie zum Beispiel einen Türrahmen, beschädigen können.Such locking devices of the prior art are used equally with only one locking element as well as with several locking elements and with a multiple lock. If a high pre-tensioning of the control element is required to reliably reach the closed position, this high pre-tensioning can no longer only be achieved by "falling into the lock" of a door or the like. The force required to pretension the locking spring would be too great for this, so that the components subjected to a corresponding spring force are not only caused by an acoustically perceptible "beating" the door can be moved against the spring force but can also damage other components, such as a door frame.
Die Aufgabe der vorliegenden Erfindung ist daher, eine Schließvorrichtung der eingangs genannten Art zu schaffen, mit der bei einem Schließvorgang auch eine hohe Vorspannung eines Riegelelements ohne die vorstehend genannten Nachteile erreicht werden kann.The object of the present invention is therefore to create a locking device of the type mentioned at the outset with which, during a locking process, a high pretensioning of a locking element can also be achieved without the disadvantages mentioned above.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Riegeldruckfeder in der Öffnungsstellung in einem Zustand vorspannungsfrei ist und in einem anderen Zustand, nach einem Drehen des Drückers, die erste Vorspannung aufweist.The object is achieved according to the invention in that the locking pressure spring in the open position is free of prestress in one state and has the first prestress in another state after the lever has been turned.
Mit der vorliegenden Erfindung ist es nunmehr möglich, dass Vorspannung einer Riegeldruckfeder zur Unterstützung der Schließbewegung wenigstens eines Riegelelements durch eine manuelle Kraftübertragung, d.h. durch Drehen des Druckers zu erreichen. Dadurch kann die zum Auslösen eines Schließvorgangs notwendige Federkraft, mit der ein oder mehrere andere Bauteile der Schließ-und Öffnungsmechanik beaufschlagt sein können, so gering gehalten werden, dass eine Tür oder dergleichen auch weiterhin sanft in ein Schloss fallen kann, um allein dadurch den Schließvorgang bzw. die Schließbewegung des wenigstens einen Riegelelements in seine Schließstellung auszulösen.With the present invention, it is now possible to preload a locking pressure spring to support the closing movement of at least one locking element by manual force transmission, i.e. by rotating the printer. As a result, the spring force required to initiate a closing process, with which one or more other components of the closing and opening mechanism can be acted upon, can be kept so low that a door or the like can continue to fall gently into a lock to initiate the closing process or to trigger the closing movement of the at least one locking element into its closed position.
Ein weiterer Vorteil der vorliegenden Erfindung besteht darin, dass der Drücker über einen Spannhebel mit der Riegeldruckfeder in Verbindung steht und der Spannhebel beim Drehen des Drückers die Vorspannung der Riegeldruckfeder aufbaut. Ein solcher Spannhebel hat sich als ein konstruktiv günstiges Bauteil erwiesen, um die durch das Drehen des Druckers erzeugte Kraft auf die Riegeldruckfeder zu übertragen.A further advantage of the present invention is that the pusher is connected to the bolt compression spring via a tensioning lever and the tensioning lever builds up the bias of the bolt compression spring when the pusher is turned. Such a tensioning lever has proven to be a structurally favorable component in order to transfer the force generated by the rotation of the printer to the bolt compression spring.
Ein weiterer Vorteil der vorliegenden Erfindung ist, dass der Spannhebel bei Erreichen einer Position, die der ersten Vorspannung der Riegeldruckfeder entspricht, arretierbar ist. Auf diese Weise wird die Riegeldruckfeder mittels einer Drehbewegung des Drückers auf eine vorbestimmte erste Vorspannung vorgespannt und diese erste Vorspannung konserviert, bis diese für einen Schließvorgang benötigt wird.Another advantage of the present invention is that the tensioning lever can be locked when it reaches a position which corresponds to the first pretensioning of the bolt compression spring. On In this way, the latch compression spring is preloaded to a predetermined first preload by means of a rotary movement of the handle, and this first preload is preserved until it is required for a closing process.
Ein weiterer Vorteil der vorliegenden Erfindung ist, dass die Arretierung des Spannhebels durch einen unterhalb des wenigstens einen Riegelelements angeordneten Rasthebel erfolgt. Durch die Wahl eines unterhalb des wenigstens einen Riegelelements angeordneten Rasthebels als Arretierung für den Spannhebel kann die Bauweise der erfindungsgemäßen Schließvorrichtung sehr kompakt ausfallen.Another advantage of the present invention is that the clamping lever is locked by a latching lever arranged below the at least one locking element. By choosing a locking lever arranged below the at least one locking element as a locking device for the tensioning lever, the design of the locking device according to the invention can be very compact.
Ein weiterer Vorteil der vorliegenden Erfindung ist, dass eine Auslöseplatte zum Auslösen der Schließbewegung des wenigstens einen Riegelelements eine zweite Vorspannung hat, die geringer als die erste Vorspannung des wenigstens einen Riegelelements ist. Die Auslöseplatte ist an einer Stulpschiene vorgesehen und ragt in Richtung Schließblech eines Türrahmens vor. Beim Schließen einer Tür, also wenn die Tür "ins Schloss fällt", wird die Auslöseplatte in die Schließvorrichtung entgegen der Wirkrichtung der zweiten Vorspannung zurück gedrückt, bis der Spannhebel über die Schließ-und Öffnungsmechanik aus seiner Arretierung gelöst wird. Da diese zweite Vorspannung sehr viel geringer ist als die erste Vorspannung bedarf es für reine Auslösung keiner großen Kraft. Diese Kraft ist jedenfalls sehr viel kleiner als die Federkraft der Riegeldruckfeder.Another advantage of the present invention is that a release plate for triggering the closing movement of the at least one locking element has a second preload which is less than the first preload of the at least one locking element. The release plate is provided on a faceplate and protrudes in the direction of the strike plate of a door frame. When a door is closed, that is, when the door "falls into the lock", the release plate is pushed back into the locking device against the direction of action of the second preload until the clamping lever is released from its locking position via the locking and opening mechanism. Since this second preload is much lower than the first preload, no great force is required for pure release. In any case, this force is much smaller than the spring force of the latch compression spring.
Ein weiterer Vorteil der vorliegenden Erfindung ist, dass die Schließ-und Öffnungsmechanik eine Mehrfachverriegelung mit einer Mehrzahl von Riegelelementen umfasst. Durch die Trennung zwischen der notwendigen Auslösekraft zum Auslösen einer Schließbewegung des wenigstens einen Riegelelements und der notwendigen Schließkraft zum Durchführen der Schließbewegung des wenigstens einen Riegelelements können mit der vorliegenden Erfindung nicht nur mehrere Riegelelemente in ein und derselben Schließvorrichtung sondern auch mehrere Regelelemente einer sogenannten Mehrfachverriegelung mit zuverlässiger Schließkraft in die Schließstellung bewegt werden. Die dafür erforderliche Auslösekraft bleibt dabei immer gleich, d.h. gering.Another advantage of the present invention is that the closing and opening mechanism comprises a multiple lock with a plurality of locking elements. Due to the separation between the necessary triggering force to trigger a closing movement of the at least one locking element and the necessary closing force to carry out the closing movement of the at least one locking element, with the present invention not only several locking elements in one and the same locking device but also several control elements of a so-called multiple lock can be reliably Closing force can be moved into the closed position. The release force required for this always remains the same, ie low.
Weitere Vorteile der Folge Erfindung ergeben sich aus den Merkmalen der weiteren Unteransprüche.Further advantages of the following invention result from the features of the further subclaims.
