Description

field of technology

The invention relates to a lock with a bolt that can be moved by rotating a lock cylinder between a closed position and a pre-locked position that is moved out of a housing, and with a main slide that is arranged in the housing and has teeth that mesh with a peripheral toothing of a transmission gear wheel, which in the pre-locked position of the Bolt assumes a first position, from which it can be moved into a second position by attacking a locking element of the locking cylinder when it rotates on a driver of the main slide, taking the bolt with you, into its closed position, from which it can be displaced by attacking the locking element when it rotates in the opposite direction can be shifted back to the first position.

State of the art

A generic lock is in the DE19905597C2 disclosed. When the lock cylinder is rotated in an opening direction and when the lock cylinder is rotated in a pre-locking direction, a locking element of a lock cylinder acts on a driver of a main slide in order to shift the latter between two positions. The displacement of the main slide is accompanied by a transverse displacement of a bolt.

A panic lock, in which both the latch and the bolt are pulled back when the handle is actuated, is DE 10 2004 013 646 A1 described. A lock that locks automatically by actuating a control latch is out of the DE 10 2012 111 526 A1 previously known.

Summary of the Invention

The invention is based on the object of further developing the lock of the generic type in a way that is advantageous in terms of use.

The object is achieved by the invention specified in the claims, with the subclaims representing advantageous developments of the lock specified in independent claim 1.

As a further development of a generic lock, the invention proposes a drive slide which has a toothing meshing with the peripheral toothing and has a nose which is acted upon by the closing element during rotation in the opposite direction.

This drive slide serves to shift the main slide from, for example, the tumbler function position to, for example, the open position. According to the invention, the drive slide has teeth, which are in particular straight teeth. This toothing can mesh with a peripheral toothing of a transmission gear. The transmission gear can have several functions. One function is the shifting of the main slide from the locked function position to the open position. For this purpose, a straight toothing of the main slide meshes with the circumferential toothing of the transmission gear. A second function is to shift the bolt to the pre-locked position. For this purpose, a transmission gear cooperating with the toothing of the drive slide can have a crank arm or a further peripheral toothing. The crank arm can engage the latch. The additional peripheral toothing can engage in a toothing of the bolt. Crank arm and toothing of the bolt can be arranged in such a way that a bolt retraction takes place only after a clearance, this is provided in particular if the transmission gear is also to move the main slide.

The invention is also based on the sub-task of specifying a system with which both self-locking locks and anti-panic locks can be manufactured inexpensively and/or specifying an anti-panic lock or a self-locking lock that is functionally improved.

Such advantageous developments are presented in the dependent claims 10-13.

Description of the embodiments

The lock shown in the drawings is constructed, for example, from parts of a kit in a modular manner that it can be constructed either as a self-locking lock or as a non-self-locking lock by exchanging one or more structural units. In both constructions, the lock preferably has an anti-panic function, in which not only a latch 6 but also a bolt 5 can be pulled back by actuating a nut 7, so that a door equipped with such a lock can be opened simply by actuating the handle. If the lock in a structure according to the Figures 1a to 5b is constructed as a self-locking lock, it also has the function that when a door equipped with the lock is closed, it automatically enters a closed position, ie the bolt 5 advances from a closed position to a pre-closed position. The force required for this is stored in a force accumulator 10 .

That in the Figures 1a to 5b Castle shown has a housing 1, which is formed by a forend 2, a lock base 3 and a lock cover 4. A bolt 5 with a bolt head 5' and a bolt tail 5" and a latch 6 with a latch head 6' and a latch tail 6" are mounted between the lock base 3 and the lock cover 4. The latch 6 can be withdrawn with a nut 7 which is also mounted between the lock base 3 and the lock cover 4 and which can displace an arm support 40 with a nut arm. For this purpose, a first nut arm 7' fastened to the arm carrier 40 acts on the latch tail 6". A transmission slide 33 is coupled to a nut spring 32, which acts on a transmission projection 34 of the nut 7 in order to reset the nut after it has been turned.

A second nut arm 7" engages a driver 26 of a main slide 8 in order to shift the main slide 8 from a tumbler functional position to an open position. In the tumbler functional position, a tumbler projection 28 of the first main slide 8 engages in a bearing opening 29 of the bolt tail 5" Figure 4a ).

A release element 17 is provided to hold the main slide 8 in the open position. The release element 17 has the form of a two-armed lever. At the end of a first lever arm there is a locking lug 18 which engages under a locking step 19 of the main slide 8 . In addition to the locking step 19 further locking steps 42 are arranged tooth-like. The second arm of the release element 17 forms an actuating arm 48 which can be acted upon by an actuating shoulder 41 of the latch tail 6" when the latch 6 is in a fully pre-closed position ( Figure 4b ) occupies. A spring element 49 is provided, which rests in an arcuate recess of the release element 17 designed as a flat piece and which is supported on a supporting shoulder of a bearing body 11 . The bearing body 11 has fastening projections 69, 69' on two sides facing away from one another, which projections can be inserted into fastening openings 70, 70' of the lock base 3 and lock cover 4.

A bearing axis 47 of the release element 17 is mounted in a bearing bore 59 of the bearing body 11 which is made of plastic and is held between the lock cover 4 and the lock base 3 .

In a particularly further bearing opening 29 of the bearing body 11 sits a latching body 12 which has the shape of a round pin with a head 12' of enlarged diameter. The end of the locking body 12 facing away from the head forms a locking projection 12" which, in a blocking position ( figure 1a ) lies in the movement path of a latch tail 6". In the bearing opening 29 there is also a spring element 35, through which the shaft of the locking body 12 reaches. The spring element 35 is supported on a step of the bearing opening 29 and supports the head 12'. The latter supports in its blocking position on a control surface 37 of the control latch 13. Next to the control surface 37 there is a control incline 36 along which the head 12' can slide when the control latch 13 moves from an actuated position ( Figure 2a ) to a non-actuated position ( Figure 1a ) is relocated. In addition, a clamping ring 39 is seated on the shaft of the locking body 12, which clamps the locking body 12 in the bearing opening 29. The bearing axis 47 of the release element 17 is tied to the bearing body 11 with a similar clamping ring. The bearing body 11 forms a detachable structural unit together with the locking body 12 and the release element 17 .

The force accumulator 10, which acts on the main slide 8, is also a detachable structural unit. Two fastening projections 45' protrude from a bearing block 45 and are inserted in fastening openings 44 in the lock base 3 and lock cover 4. A bearing pin 46 which carries a helical compression spring 58 protrudes from the bearing block 45 . The helical compression spring 58 is supported on the bearing block 45 on one side and on a driver 27 of the main slide 8 on the other side. For this purpose, the bearing pin 46 reaches through a hole in the driver 27.

The functioning of the Figures 1a to 5b shown lock is the following:

Starting from one in the Figures 1a and 1b illustrated operating position in which the case occupies its incomplete pre-closed position in which the case tail 6 "is supported on the locking projection 12 'in which the Control latch 13 occupies its non-actuated position, the bolt 5 is closed and the main slide 8 is held in an open position 8 by the release element 17, self-locking occurs when a door equipped with the lock is closed. When the door is closed, latch 6 and control latch 13 are thereby displaced into the lock housing, in which latch head 6' and head 13' of control latch 13 run onto a strike plate 55. When the control latch 13 is shifted back, the control surface 37 moves away from the end face of the head 12', so that the spring element 35 can shift the latching body 12 upwards. As a result, the latching projection 12" moves out of the path of movement of the latch tail 6". Now trap 6 falls, as in the Figure 3a shown, in the associated latch entry opening 56, the latch head 6" can pass the latching projection 12".

While in the in the Figure 1b If, in the position shown, the actuating shoulder 11 of the latch tail 6" is in front of the actuating arm 48, the actuating shoulder 41 can now act on the actuating arm 48, so that the release element 17 is shifted into its release position, in which the locking lug 18 is released from the locking step 19 ( Figure 4b ), So that the first main slide 8 is released to the stored power of the energy accumulator 10 in the Figures 4a and 4b shown tumbler function position, in which the tumbler projection 28 rests in the bearing recess 29 of the bolt tail 5".

The linear movement of the first main slide 8 is transmitted via a transmission gear 21 to a crank arrangement, with which the bolt 5 is shifted into the closed position. For this purpose, the body forming the transmission gear wheel 21 and its circumferential toothing 21 ′ has a crank arm 63 and a toothing 66 which engages in a counter-toothing 65 of the bolt 5 .

• Durch Betätigen der Drückernuss 7 wird mittels des zweiten Nussarmes 7" der erste Hauptschieber 8 angehoben. Die Verzahnung 24 greift in die Verzahnung 21' des Übertragungszahnrades 21 ein, um den Riegel 5 nach einem Freigang, bei dem der Zuhaltungsvorsprung 28 die Lageröffnung 29 verlässt, zurückzuziehen. Der Nussarm 7' zieht die Falle 6 zurück.
• Durch einen äußeren Druck auf einen Taster 43, der an seinem Ende eine Steuerschräge 43' aufweist, die bei einer Verlagerung des Tasters 43 den Zuhaltungsvorsprung 28 aus der Lageröffnung 29 heraushebt, so dass anschließend der Riegel 5 von außen in die rückgeschlossene Stellung gebracht werden kann. Über das mit der Linearverzahnung 24 zusammenwirkende Übertragungszahnrad 21 wird der erste Hauptschieber 8 in eine Öffnungsstellung gebracht.
• Durch Drehen eines in eine Schließzylinder-Einstecköffnung 25 eingesteckten Schließzylinder. Dessen Schließglied greift an einem Mitnehmer 31 des ersten Hauptschiebers 8 an, um ihn in die Öffnungsstellung zu verlagern.

To get the lock from the to the Figures 4a and 4b To bring the closed position shown into an open position, there are different ways:

• By actuating the follower 7, the first main slide 8 is raised by means of the second follower arm 7". The toothing 24 engages with the toothing 21' of the transmission gear wheel 21 in order to move the bolt 5 after a free movement, in which the tumbler projection 28 leaves the bearing opening 29. The nut arm 7' pulls the trap 6 back.
• By external pressure on a button 43, which has a control bevel 43' at its end, which lifts the tumbler projection 28 out of the bearing opening 29 when the button 43 is displaced, so that the bolt 5 can then be brought into the closed position from the outside . The first main slide 8 is brought into an open position via the transmission gear 21 interacting with the linear toothing 24 .
• By rotating a lock cylinder inserted into a lock cylinder insertion opening 25. Its closing element acts on a driver 31 of the first main slide 8 in order to move it into the open position.

The Figures 7a to 8b show the lock according to the invention in a structure as a non-self-locking anti-panic lock. A first main slide 8, which is designed differently compared to a second main slide 9, replaces the second main slide 9. The energy accumulator 10 (cf. Figure 6a ), the bearing body 11 (cf. Figure 6b ), the tax trap 13 (cf. Figure 6d ) and the second main slide 9 (cf. Figure 6e ) have been removed.

A retaining element carrier 15 (cf. Figure 6f ), a drive slide 22 (cf. Figure 6g ) and the first main slide 8 (cf. Figure 6h ) has been used instead of the second main slide 9.

The holding member carrier 15 is a plastic part which is supported on a projection in the lock housing with a helical gear spring 60 seated on a pin 61 . The other end of the helical gear spring 60 engages one end of the holding member carrier 15 . The retainer support 15 has a spigot 67 which carries an annular retainer 14 thereon. A bearing pin 52 passes through a slot 51, which acts as a bearing eye, which also passes through a slot 62 of the second main slide 9.

The first main slide 8 has two locking flanks 16 which form a V-shaped locking niche. The holding member 14 can engage in this latching niche in order to move the first main slide 8 in an open position ( Figure 7b ) to keep. The holding member carrier 15 also has two holding projections 64 pointing away from one another, which engage in fastening openings 68 of the lock base 3 and lock cover 4 in order to bind the holding member carrier 15 in the lock housing. The attachment openings 68 are elongated holes in which the attachment projection 64 can move.

Lock base 3 and lock cover 4 also have a guide slot 53 in the area of the lock cylinder insertion opening 25 , which runs obliquely to the displacement direction of the second main slide 9 , ie also obliquely to the forend 2 . In this guide slot 3 is in each case a guide pin 57 one in the Figure 6g illustrated drive slide 22. The drive slide 22 has a back 22' running in a straight line and linear toothing 23 opposite the back 22'. A lug 22" is also provided, which can be acted upon by the locking element of a locking cylinder inserted into the locking element insertion opening 25 in order to linearly displace the drive slide 22 .

In an alternative embodiment that is not shown, the slot 53 can also be curved and the teeth 23 can also be curved.

The toothing 23 meshes with the peripheral toothing 21' of the transmission gear 21. Since the peripheral toothing 21' also simultaneously meshes with the toothing 24 of the first main slide 8, a displacement of the drive slide 2 is transmitted directly to the second main slide 9 with a reversal of movement. The first main slide 8 can thus be shifted into an open position by the locking element of the locking cylinder engaging the driver 31 or by engaging the locking element on the lug 22" from the open position into the tumbler functional position.

The first main slide 8 is held by the holding member 14 in the open position. The holding member 14 forms a latching pin which engages in a latching niche formed by the two latching flanks 16 . The latching niche is formed by two latching flanks 16 which run essentially in a straight line and which are at an angle of greater than 90° to one another. The niche opens in a direction pointing away from the forend 2 .

The lock is opened in the manner described above, either by turning the follower 7, by external action on the button 43 and the bolt 5, or by actuating a lock cylinder. <b>List of reference characters</b> 1 Housing 19 rest stage 2 forend 20 spring element 3 castle floor 21 transmission gear 4 castle cover 21' peripheral teeth 5 bars 22 drive slide 5' bolt head 22' Move 5" latch tail 22" Nose 6 Cases 23 linear gearing 6' trap head 24 linear gearing 6" trap tail 25 Lock link insertion hole 7 nut 26 driver 7' first nut arm 27 driver 7" second nut arm 28 locking projection 8th first main slider 29 warehouse opening 9 second main slider 30 connecting rod 10 energy accumulator 30' connecting rod 11 bearing body 31 driver 12 locking body 32 Nutspring 12' Head 33 transmission shifter 12" locking projection 34 transmission advantage 13 tax trap 35 spring element 13' Head 36 control slope 13" tail 37 control surface 14 holding link 38 spring element 15 holding link carrier 39 clamping ring 16 detent edge 40 arm carrier 17 release item 41 operating shoulder 18 detent 42 Teeth 43 button 43' control slope 44 mounting hole 45 bearing block 45' mounting boss 46 bearing journal 47 bearing axis 48 operating arm 49 spring element 50 buck 51 bearing eye 52 bearing journal 53 guide slot 54 support pivot 55 locking plate 56 trap entry opening 57 pilot 58 compression spring 59 bearing bore 60 spring element 61 Pen 62 Long hole 63 crank arm 64 retaining projection 65 gearing 66 gearing 67 cones 68 mounting hole

Lock according to claim 1, in particular designed as a self-locking lock, in which the main slide (8) is held by a release element (17) in its latching position in the second position acted upon by a force accumulator (10), with a nut (7) rotatably mounted in the housing (1) for retracting a latch (6), which is acted upon in an advanced position by means of a spring element (20), into a retracted position, with a control latch (13) which, when actuated, releases a displacement of a latching element (12) so that upon a subsequent displacement of the latch (6) from its retracted position into its advanced position, the release element (17) is displaced into a release position, so that the main slide (8) is displaced from a retracted position into an advanced position into the first position, while entraining the latch (5), wherein the release element (17) is a pivot lever which, in its latching position, engages with a latching nose (18) under a latching step (19) of the main slide (8) and is brought into the release position by an actuating shoulder (41) of the latch (6).
13. Lock according to claim 1, in particular a self-locking lock in which the main slide (8) is held by a release element (17) in its latched position in the second position acted upon by a force accumulator (10), with a nut (7) rotatably mounted in the housing (1) for retracting a catch (6), which is acted upon in a pre-closed position by means of a spring element (20), into a retracted position, with a control latch (13) which, when actuated, releases a displacement of a latching element (12) so that upon a subsequent displacement of the catch (6) from its retracted position into its pre-closed position, the release element (17) is displaced into a release position, so that the main slide (8) is displaced from the second position into the first position while entraining the latch (5) into an advanced position, wherein the detent element (12) is a detent body (12) mounted in a bearing opening (29) of a bearing body (11) fastened to the housing (1), which detent body (12) is linearly displaceable parallel to the direction of displacement of the main slide (8).
