Abstract

The drive rod lock has an adjustable coupling component (11) between the catch (1) and one of both nut halves (6). The nut halves are movable out of a central neutral position and work in conjunction with a drive rod connecting slide (22), which is displaceable from each of the two nut halves by press button operation. Each nut half has an operating arm (10), both operating arms are located in planes spaced from each other in an axial direction. In a plane applicable to the distance space between the two arms is located a stop (9) of the operating section (7) of the catch. The coupling component is formed as a pin extending in the distance space and inserted in a hole in the operating arm.

Description

The invention relates to a lock, in particular a Espagnolette lock according to the preamble of claim 1.

Such a drive rod lock is from DE-OS 28 45 957 known. The espagnolette lock disclosed there has a handle follower consisting of two halves on. The halves are in the axial direction to each other, whereby each half is assigned a press mandrel. With a pusher mandrel, especially the inner pusher mandrel, the latch can be pulled back by pushing the button. For this purpose, the one assigned to the inner handle Half of the nut on an arm with an actuating projection the trap interacts. The two handle halves are like the two nut halves, so that the actuation of the inside handle or Outside handle the opposite other handle or the nut half assigned to this handle is unaffected leaves. In the well-known castle, the trap is only retractable by actuating the inner half of the nut. Operating the outer half of the nut has no latch retraction result. Both halves of the nut are in there too Reversible direction. When the Pushers in this opposite direction are shifted a drive rod arranged in the lock case.

A lock consisting of two handle halves is also known from DE-PS 40 26 080.

An espagnolette lock with inside and outside handle, at which the push button actuation in one direction Trap withdrawal and a trigger actuation the displacement of a drive rod in the opposite direction causes is known from DE-OS 40 41 537.

A disadvantage of the lock mentioned at the outset is that limited usability. Such a castle can only be designed for left-handed or right-handed people Doors are used.

The invention is therefore based on the object Advantageous further training of the generic lock.

The problem is solved by the one specified in claim 1 Invention.

Advantageous further developments of the Invention.

According to the configuration according to the invention is a Lock, especially given espagnolette lock, at which with simple means a left / right change is possible. As a result of the mirror-symmetrical design Halves of nuts can either be one or the other or both nut halves can be coupled with the trap. The coupling links are detachable and therefore also after Production of the lock relocatable or relocatable, so that the coupling between the trap and the nut is adjustable is. The case is preferably an actuating section on the tail side assigned. This operating section can be designed as a projection. It is further preferred that a lock lever assigned to the lock which acts on this operating section. In A preferred development of the invention provides that the nut actuation with the bolt locked Is blocked. It is also conceivable instead of Nut the displaceability of the connecting rod connecting slide to lock. This can be done in the actuation path the nut projecting locking member may be provided, which is assigned to a gate valve. The gate valve can move together with the bolt exclusion in the bolt pre-movement be relocated. The gate valve has preferably two fork-shaped locking tines, each locking prong with a locking projection one of the two nut halves interacts. Every nut shows preferably an actuating arm. The should two actuating arms in the axial direction (pusher mandrel axis) be spaced from each other so that between the there is a space between both arms. In this space can the actuating section when the nut is turned of the trap tail. The coupling member can either the trap tail or the nut arm be assigned. The coupling link is the nut arm assigned, it is preferably provided that it is in the Distance space protrudes, so that the nut when turning Coupling member the operating section of the trap tail acted upon and thereby pulls back the trap. Is the coupling piece is assigned to the trap tail it is preferably arranged in the region of the actuating section and protrudes axially into the path of movement one or both nut arms. Each nut half is preferred each in a cushioned middle position held. The sprung middle position can by a two-armed slider can be maintained, such as it is described in detail in DE-OS 40 41 537. It it is preferred that such a sprung slider is provided twice, with each slider on separately one of the two nut halves works. Both halves of the nut each have a radial edge recess in which a tooth of a pivot lever protrudes. The opening of the Radial recess is much larger than the effective one Thickness of the tooth, so that there is a nut clearance. Such access is also in the OS 40 41 537 described in detail and serves that after a drive rod shift either in the open or in the blocking position the nut back in the neutral position is returned. Between the two edge areas, which the radial recess is assigned to a clearance is also provided, in which a portion of the pivot lever protrudes. Each two protrude from this subsection in the axial direction Teeth of the swivel lever.

A development of the invention provides that Coupling member not the operating arm of either one Nut halves is assigned, but the trap tail. The coupling member is preferably the actuating section assigned to the trap tail and in Transversely to the lock level shiftable. The relocability of the coupling member can by a spindle drive done, which is in the form of a trap tail rotatably arranged screw is formed. The The spindle drive can be operated using a screwdriver become. The spindle is in at both ends Operating section stored so that in a space a narrow actuator can be moved in the transverse direction is such that it is in one extreme position acted upon by an actuating arm of one nut half is, but not from the other and in the other Extreme position can be acted upon by the other half of the nut is, with the other half of the nut goes free.

The functioning of the lock corresponds essentially that of the castle according to OS 40 41 537. The design is also described in parts there.

The lock according to the invention has a lock case on which a lock base 35 and a lock cover 34 has. The lock has a cuff on the front on which has openings through which a trap head 8 a trap 1 and a bolt 29 pass through. There is an espagnolette connecting slide in the lock case along the cuff 22 out. To drive the connecting rod slide serves a pivot lever 19, which has a first arm in which a slot 20 is provided is; a pin 21 projects in the latter. The pin 21 is connected to the connecting rod connecting slide 22. By pivoting the pivot lever 19 around The axis of rotation 40 becomes the connecting rod connecting slide 22 shifted along the cuff. 1 is the a drive rod connecting slide position corresponding to the open position is shown and in FIG. 2 a position of the connecting rod connecting slide assigned to the blocking position 22 shown.

The pivot lever 19 has two axially opposite Pin or teeth 18 on which by a section 44 are separated. The two cones 18 protrude into a radial recess 17 of the two nut halves 5, 6 a. The radial recess 17 has one circumferential angle such that each of the two nut halves 5, 6 is held in the neutral position, independently the position of the swivel lever 19 between its two end positions (Fig. 1, Fig. 2) is.

The neutral position of the two nut halves 5, 6 is each maintained by a sprung slide 14, 36. The slide 14, 36 has two slide arms 15 on, which cooperate with drivers 16 of the nut. Regarding the interaction of sliders 14, 36 with the drivers 16 of the two nut halves refer to OS 40 41 537.

A lock 29 is provided in the lock housing, which by actuating a profile locking cylinder is closable. The lock cylinder has one Locking member 31, which with a tumbler 30th cooperates. On the latch is the arm of a change lever stored, which can be acted upon by the closing member 31 is. The second arm of the change 31 is applied an operating section 7 of the trap tail 2 in such a way that the latch 1 is withdrawn when the switch is actuated becomes.

The espagnolette lock has two in the axial direction of the Lever halves 5 and 6 in series on. The nut halves 5, 6 are symmetrical and each have an arm 10. The arms are 10 spaced at least in the region of their free ends. A space is formed between the trap arms in which a stop 9 of the actuating section 7 case 1 protrudes. Each of the two arms 10 points a hole in which a coupling pin can be inserted is. 6, the coupling pin 11 is in the right nut half 6 and in Fig. 7 is the coupling pin 11 inserted in the left nut half 5. Corresponding 6 is retracted when actuated of the pusher 4 and according to FIG. 7 when the pusher is actuated 3. The two nut halves 5, 6 are one below the other not in rotation, but can be against each other without Rotary drive can be rotated. Likewise, the two pusher mandrel sections 3, 4 rotated against each other become. The ends of the two axially aligned with each other arranged mandrel sections 3, 4 are spaced from each other. They are located in a blind bore 23 Rectangular cross section of the respective nut half 5, 6. A coupling pin 38 is provided which consists of a of the two end faces of the press mandrel 4 protrudes and in the opposite end of the trigger mandrel section 3 protrudes. The pin is so round designed that the two pushers 3, 4 against each other can be twisted.

The mutually mirror-symmetrical nut halves 5, 6 slide on one of their end faces. The nut halves face the end faces 5, 6 on a cylindrical collar, which in a corresponding opening of the castle ceiling 34 or Lock base 35 is inserted. It is envisaged that in both arms 10 of the two nut halves 5, 6 a coupling pin 11 can be inserted. The coupling pin 11 protrudes at most up to the level of the joint between the two nut halves in the space. In particular, it protrudes into the space between the two free ends of the arms 10. A section 9 lies in the plane of the parting line the case, which the releasable coupling member 11 at Nut actuation applied.

On the face of the Nut 5, 6 driver projections 16 are arranged on which each have a prong 15, 37 of a slide 14 lies on. The drivers 16 are approximately diametrically opposite arranged so that depending on the direction of rotation The slider is accompanied by a compression of the Spring 32, 33 is shifted. The two springs 32, 33 are aligned with each other in the lock case and act on the slide 14, 36 elastically.

Opposite the slide is on the lock bottom 35 or under the lock cover 34 a locking slide 27 arranged. The locking slide 27 has two in parallel extending tines 45, 46, each tine 45, 46 is provided with a locking lug 25 which has a locking projection 26 the nut cooperates. The locking lug 25 undermines the locking projection 26 when the slide 27 is shifted in the bar exclusion direction. Hereby the button 24 can no longer be pressed down to move the drive rod to the open position. To take with the latch, the Locking slide 27 on a driver projection 28, which of the locking of the bolt or of the bolt 29 itself is acted on, so that when locking the bar the locking lug 25 relocated under the locking projection 26 is and when moving the bolt 29 back accordingly is shifted away under the locking projection 26, so that in this position the nut can be turned. Between the two tines 45, 46 is the pivot lever 19th

The functioning of the lock is as follows:
In the coupling position shown in FIGS. 1 to 6, the nut half 6 is coupled to the actuating sections 7 of the case 1. If in this coupling position with the drive rod in the open position (FIG. 1) the pusher 24 is pressed down (FIG. 3), the coupling pin 11 engages the stop 9 of the fastening section 7 and pulls the latch back. Along with this nut rotation, the slide 14 is shifted. When the trigger 24 is released, the nut is moved back into the neutral position shown in FIG. 1 due to the spring-loaded slide 14. The spring 12 pushes the latch into the extended position. As a result of the free passage in the radial opening 17, the pivot lever 19 remains undeflected when this handle is actuated.

On the other hand, the opposite handle 3 is put together pivoted with the nut 5, there is no entrainment of the Actuating section 7 of the case, since the nut arm 10 of the Nut half 5 is not provided with a pin. Of From this side of the lock, the latch is not activated by a handle retractable, but only by actuation of the profile locking cylinder by means of a change operation about the change 13.

Starting from the neutral position shown in FIG. 1, the handle (outside handle or inside handle) shifted upwards (Fig. 2), the Swivel lever 19 by acting on tooth 18. Along with this pivoting of the pivot lever 19 is the connecting rod connecting slide 22 upwards shifted. The lock is now shown in Fig. 2 Locked position. In this position the When the button is released, a spring-loaded takes place Reset one of the two nut halves 5, 6 in the Neutral position.

In the latter connecting rod connecting slide position (Locked position) the bolt 29 can be actuated pre-lock the profile locking cylinder (cf. Fig. 5). In this position - along with the Riegelvorschluß- shifted a gate valve so that a locking lug 25 of the locking slide 27 under one Locking projection 26 of the nut half 5, 6 slides so that the Pusher 24 can no longer be pressed down.

If the bolt is closed, so too Gate valve with moved back so that by actuation of the inside or outside handle either the nut half 5 or the nut half 6 can be pivoted. Accompanying with such a pivoting one of the two Nut halves 5 or 6 by pressing the trigger down 24, the tooth 18 is acted on in the opposite direction, so that the pivot lever 19 in that shown in Fig. 1 Neutral position is shifted back along with an opening shift of the connecting rod connecting slide 22.

When the lock changes from a left-handed to a right hinged door should be moved, see above only the trap head 8 needs to be turned through 180 °. For this purpose, a cylindrical trap tail 2 is provided, which with a screw 39 in a trap end piece, which is formed by the actuating section 7 is attached to the latter. Loosening the screw 39 enables the trap to be turned 8. In addition the pin 11 must still be pulled out of the nut half 6 and (as shown in Fig. 7) in the nut half 5 can be inserted. Then the nut half 6 of the Trap uncoupled.

In the embodiment shown in FIGS. 8 to 10 the coupling member 47 is the trap tail, namely assigned to the actuating section 107. The For this purpose, the actuating section 107 has a U-shaped one Recess in which a plate lies, which with an end region 47 'acted upon by the latch arm 110 is. The plate 47 has approximately a thickness which corresponds to half of the U-space. Between the two U-legs is a screw 48 as Threaded spindle clamped. One turn of the screw 48 does not cause the screw to move relative to the Actuating section 107. The coupling member 47 has an internal thread into which the external thread of the Screw 48 protrudes. The screw 48 thus acts as a threaded spindle. By rotating the screw 48 which the coupling member 47 transversely to the lock extension plane relocate it either from the operating arm 110 of the nut half 106 or from the actuating arm 110 ' Nut half 105 can be applied. The each the other half of the nut is then released without the trap is operated. As can be seen in Fig. 10, the Nut halves parallel to each other such that the two Actuating arms 110, 110 'separated by a free space are. This enables a clean separation of movements by transverse displacement of the coupling member 47.

The trap tail 102 of the trap 101 has a pocket 49 in which an end region of a change lever 113 immersed. The trap tail 102 sits back out into an operating section 107, which the Has recess in which the coupling member 47th is displaceable transversely.

The two nut halves 105, 106 are in their neutral Center position held by a slide 114, which is acted upon by a compression spring 133. The Slider 114 has two fork prongs 15 which act on corresponding driver 16 of the nut halves.
