Abstract

The closure has a latch (27) and an auxiliary latch synchronously locked by key actuation. A latch bolt and an auxiliary latch bolt are synchronously retracted by pusher latch or change actuation. A slider is drive-connected with a driving bar (26') in a main lock. A rotating arm (7) designed as double arm lever and works on the slider, where the slider is attached to the rotating arm and the latch bolt by gears (23). A stop (38) at the slider or the rotating arm permits a movement of the slider in an inference direction by the rotating arm.

Description

The invention relates to a drive rod lock according to the preamble of claim 1.

Espagnolette locks of the aforementioned type are already known. From the DE 19901661 A1 An espagnolette lock is known in which, in addition to a trap and a bolt having main lock still an additional lock is provided. The additional lock also includes a latch and a latch, wherein the latch is designed as a pivotally mounted hook. The latch and the latch of the additional lock are actuated by two drive rods. The first drive rod is associated with the case of the auxiliary lock and the case of the main lock and causes a synchronous movement of the same upon actuation of the trigger on the main lock. If a lock cylinder mounted in the main lock is used to close the latch, a change controls a change arm which cooperates with a stop of the latch so that it is retracted. With the operation of the change while the corresponding drive rod is moved via a slide of the main lock and a retraction of the case of the auxiliary lock achieved.

The actuation of the first drive rod requires a stroke that is less than the stroke for returning or precluding the latch. In addition, the closing back of the traps or day bars takes place at a later time of the key operation, such as the retraction of the bars.

In order to achieve unlocking of the day bars, the first drive rod is taken over a stop of the follower and moved in the opening direction. This movement must be independent of the movement of the bolt or the latch, so that they remain in the enclosed state. When the locked lock is operated from the outside of the building, a locked door must not be opened by the handle operation.

Similar configurations can also be found in the DE 19848864 A1 ,

The object of the invention is in contrast to provide a simplified embodiment of the espagnolette closure. This object is achieved by the means of the characterizing part of claim 1.

The design of the espagnolette closure brings a waiver of the second in the prior art still necessary drive rod with it, without the function of the espagnolette closure is affected in itself. In the known embodiments, the closing of the case of the main lock - hereinafter referred to as the main trap - and the case of the additional lock - hereinafter referred to as additional case - via the first drive rod and the movement of the bolt on the second drive rod causes. Due to the inventive design of the change arm can act on the slide in a direction causing the conclusion. For this purpose, the change arm with the exception of the locking position of the or the bolt must always be in the shift range of this associated with the slider stop. In a possible overlay of operations - for example, with the handle pressed and at the same time closing back the bolt on the cylinder - but the change arm abuts the stop and obstructs the closing back on the alternating pressure piece. This is avoided in that the stop on the slider or change arm allows movement of the slider in the direction of return swivel when swiveled.

A further development provides that the stop is formed by a pivotable in the direction of return lever on the slide, which is held spring-loaded in a driving position of the change arm. As a result, a simple embodiment of the attack is favored.

Alternatively, it may be provided that the stop is designed as a locking member mounted on the change arm, which can be guided in the direction of return to a fixed stop of the slider. The term "passable" refers to the fact that the change arm does not cause locking of the slide.

In order to simplify the design of the espagnolette even further, it is provided that the change arm is designed as a pivotally mounted double-armed lever, the first arm of the case and the second arm is associated with the stop.

It is also contemplated that the alternating pressure piece engages the arm of the change arm, which is assigned to the stop, so that there is a shorter length of the alternating pressure piece.

A particularly advantageous embodiment results from the fact that the slide has a transverse to the plane aligned with the block, which has a transverse to the direction of return hole. Since the slider is preferably made of a thin-walled sheet metal section, the block can be produced by a stamping and bending process. The molding of the trestle can be done on the one hand cost and results in the other a high load capacity with small component dimensions.

If the lever is mounted on the bracket by means of an axle and if the lever has an extension which bears against a transverse edge of the slider in the driving position of the changeover arm, a particularly high stability of the stop can be achieved and the design is comparatively simple. In order to limit the pivotal movement of the lever, other measures can be taken next to it.

A higher stability of the stop with small size is achieved in that the lever has a substantially U-shaped cross-section which engages around the block on both sides, so that the block also forms a guide for the pivoting movement and allows symmetrical loading of the axle.

It is further contemplated that the stop has a locking edge extending substantially perpendicular to the plane of the slide, so that the interaction of the stop with the change arm is ensured.

The espagnolette lock according to the FIGS. 1 and 2 has an elongated face-plate 1 with the main lock 2 arranged in the middle area thereof and auxiliary locks 3 of the same construction extending on both sides thereof.

The main lock 2 includes a trap 4, the case head 4 'as evidenced by Fig. 3 a cross-section adapted opening of the faceplate 1 passes through. At the latch tail 4 ", a spring 5 engaging the trap 4 in the direction of exclusion engages via the pusher nut 6. The latch tail 4" interacts with the pusher nut 6 a mounted on the pusher 6 arm together, as will be explained in more detail below.

Furthermore, the case 4 is displaced back by alternating operation. This takes place in cooperation with a change arm 7, which for this purpose engages with a first arm 9 in a laterally open pocket 10 of the latch tail 4 "The pocket 10 engages the arm 9 at a thickened end 11 of the arm 9, which pivot movement of the arm 9 in the bag 10 by a rounded shape allows.

Trained as a double-armed lever change arm 7 is pivotally mounted via a bolt 12 in the housing 13 of the main lock 2 and has a second arm 14. On the second arm 14, the alternating pressure piece 16 is hinged at its end 17 by means of a pivot bearing 15. The end 18 of the alternating pressure piece 16 lies in the pivoting range of a driver, not shown here, of a lock cylinder, which is accommodated in an opening 19. The driver of the lock cylinder abuts a pivoting movement in the opening direction of the end 18 of the alternating pressure piece 16 and moves it in the drawing upwards. The alternating pressure piece 16 is guided over an elongated hole 20 by a cross-pin 21 and prevented from dodging.

In addition, the driver of the lock cylinder acts in a conventional manner via a ring gear 22 on a gear 23, which by means of a wheel 24 and a rack associated therewith 25 (FIG. Fig. 11 ) of a slider 26 allows movement of the drive rod.

Below the case 4, a transversely movable to the faceplate 1 latch 27 is guided in the main lock 2. Its bolt head 28 ( Fig. 5 ) engages through the faceplate 1, while the bolt tail 29 has a therefore not visible here pin on its underside lying in the plane of the drawing, which engages in a Z-shaped Langlochausnehmung 30 of the slider 26. A movement of the slider 26 thereby causes a preclusion of the bolt 27, which is assigned in the closed position of the lock a latch opening of a striker on the fixed frame.

The change lever 7 has a beyond the pivot point of the alternating pressure piece 16 extension 32. This extension 32 is located in a plane with respect to the drawing above the slider 26 and under the alternating pressure piece 16th

About the drive rod 26 'are an additional case 33 and an additional latch 34 of the auxiliary lock 3 controllable. The connection takes place via a single drive rod 26 ', which is drive-connected with a slider 35. The slider 35 and the additional latch 34 cooperate in a conventional manner. The additional latch 33 is withdrawn via the slider 26 by means of an exchange lever 36 against a latch spring, not shown here. The change lever 36 allows a time-delayed retraction of the additional latch 33, which takes place only after the auxiliary latch 34 has been completely or at least partially withdrawn from the closing engagement.

In the daytime closing after the Fig. 3 the trap 4 and the additional trap 33 are extended. When closing the door, these are pushed back by their associated striking plates and lock behind the bars bars of the striking plates.

Should the door be locked, as in the FIGS. 1.2 . 5 and 6 represented, then the slider 26 is displaced by means of the lock cylinder and the associated therewith ring gear 22 via the gear 23. The slider 26 causes about the engagement of the above-mentioned pin on the bolt tail 29 in the slot recess 30 a Vorschließ the bolt 27 and the coupling of the slider 35 with the drive rod 26 'pivoting the additional latch 34 of the auxiliary lock third

The alternating pressure piece 16, which is shown to better clarity only partially, is carried by the engagement of the pin 21 in the slot 20 and held outside the driving area of the driver of the lock cylinder. It can be seen that the end 37 of the extension 32 of the change arm 7 in this position is above a stop 38 of the slider 26. The stop 38 is perpendicular to the plane of the slide 26 before and is carried by this.

Also, the auxiliary bolt 34 is in this position in its locking position, as shown in Fig. 6 evident.

Will be in daytime position after Fig. 3 pressed the pusher, the switching position results after FIGS. 7 and 8 , A pivoting of the follower 6 causes by a on the latch tail 4 "applied lever 40, a retraction of the case 4. In this case, the change lever 7 is pivoted so that it with the end 37 - starting from the in Fig. 3 shown position - pivoted and abuts the stop 38. A further pivotal movement of the pusher causes the change lever 7 displaces the slider 26 in the drawing upwards. As a result, the drive rod 26 'is displaced so that a stop 41 abuts on the slide 35 of the auxiliary lock 3 to the change lever 36 and this pivots, whereby the additional latch 33 is withdrawn.

Since the trap 4 and the additional trap 33 in each case via the springs 5, 42 ( FIGS. 4 and 6 ) are energized, they lock when you release the trigger in the daytime position Fig. 3 back.

From the FIGS. 9 and 10 goes out as the open position after FIGS. 7 and 8 starting from the daytime opening position FIGS. 3 and 4 done by means of the lock cylinder. For this purpose, the driver of the lock cylinder abuts when pivoting by means of the key to the end 18 of the alternating pressure piece 16. This is therefore displaced upwards and pivots the change lever 7 by its eccentric connection to the extension 32. In the manner already described above, the end abuts the stop 38 of the slider 26 and performs this together with the drive rod in the drawing up with , so that the additional trap 33 in the open position ( FIGS. 7 and 8 ). In addition, a pivoting movement of the change lever 7 is caused by the alternating pressure piece 16, which also retracts the case 4. The moving back of the drive rod is forcibly controlled via the gear 23, since when moving back the key of the ring gear 22 and thus indirectly also driven by the slide drive 24 is driven.

In the Fig. 11 is finally a special switching position recognizable, in which on the one hand via a handle operation, the nut 6 is pivoted and on the other hand via the lock cylinder and the gear 23, a movement of the slider 26th is effected. This is the case when the operator operates the pusher and at the same time wants to reach an opening via the key. If the pusher is actuated first, then the change lever 7 is already pivoted about the above-described lever 40 and the movement coupling of the change lever 7 with the latch tail 4 ", so that the extension 32 is in a position in which it stops with the 38th The stop 38 is, however, moved together with the slide 26 in the direction of return 43, so that this would lead to a fixed stop 38 that the stop 38 would abut the extension 32. The slider 26 would therefore be on a movement in the direction of return 43 prevented.

To prevent this circumstance, it is provided that the stop 38 on the slide 26 permits a movement of the slide 26 in the direction of return 43 with the change-over arm 7 pivoted. For this purpose, the stop 38 is evidenced by FIGS. 13 and 14 formed by a pivotable in the direction of return 43 lever 44 which is attached to the slider 26. The lever 44 is spring-loaded held in a driving position of the change arm 7, so that in the state of lower spring load a position corresponding to Fig. 14 results. Here, the lever 44 of the stopper 38 is aligned almost perpendicular to the plane of the slider 26 and forms a perpendicular thereto stop or locking edge 49 from. For the purpose of supporting the lever 44, the slider 26 has a bracket 45 oriented transversely to its plane, which has a bore running transversely to the direction of return 43. The bracket 45 is preferably formed by a tab of the slide 26 made of a sheet metal, which is perpendicular to its plane, so that there is an easy to manufacture, yet resilient design. The lever 44 has a substantially U-shaped cross section, which engages around the block 45 on both sides.

The lever 44 is in turn also designed as a two-armed lever, the first arm of the change arm 7 and its extension 32 is assigned, while the diametrically to the storage of the lever 44 located on the slide 26 second arm in the form of an extension 44 'in the driving position a transverse edge 48 of the slider 26 is assigned. The bearing of the lever 44 is formed by a bolt 45 and the lever 44 in the bore 46 penetrating axis 47. Evidently the FIGS. 13 and 14 extend the stop edges 49, 50 of the lever 44, the extension 32 of the change arm 7 and the side edge 48 of the slider 26th can be assigned, in parallel, so that the lever 44 can assume the above-mentioned vertical alignment with respect to the slider 26.

It can be seen that the lever 44, which is pivotably mounted on the bracket 45 by means of the axle 47, can be moved in the driving position by the changeover arm 7 (FIG. FIGS. 7 and 9 ) abuts the transverse edge 48 of the slider 26 by means of the extension 44 ', that in an opposite movement of the slider 26, the lever 44, however, by the extension 32 accordingly Fig. 13 is pivoted, so that on the one hand does not lead to a blockage of the slider 26 and that on the other hand, the stop 38 is thereby returned to the side of the extension 32 and the lever 44, which is suitable for entrainment of the lever 44 by the extension 32 is.

By the arrangement described above it is achieved that the stopper 38 on the slider 26 allows movement of the slider 26 in the direction of return 43 even when swivel arm 7 is pivoted. It is readily apparent that the stop 38 is formed as an alternative to the embodiment described above as a mounted on the change arm 7 locking member which is in the direction of return 43 at a fixed stop of the slider 26 can be moved past.
