EP0712987A2 - Lock, in particular espagnolette with bipartite handle follower - Google Patents

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 connecting rod lock according to the preamble of claim 1.

Such a drive rod lock is known from DE-OS 28 45 957. The espagnolette lock disclosed there has a handle follower consisting of two halves. The halves lie in the axial direction to one another, with each half being assigned a press mandrel. The latch can be retracted using a handle, especially the inner handle. For this purpose, the nut half assigned to the inner pusher has an arm which interacts with an actuation jump of the latch. The two handle halves, like the two nut halves, are rotationally coupled, so that the actuation of the inner handle or the outer handle leaves the opposite other handle or the nut half assigned to this handle unaffected. In the known lock, the trap can only be retracted by actuating the inner half of the nut. Activation of the outer half of the nut does not result in a latch retraction. Both nut halves can also be turned in the opposite direction. When the handle is actuated in this opposite direction, a drive rod arranged in the lock case is displaced.

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

An espagnolette lock with inside and outside handle, in which the handle actuation in one direction results in a latch retraction and a handle actuation causes the displacement of a drive rod in the opposite direction is known from DE-OS 40 41 537.

A disadvantage of the lock mentioned at the outset is its limited usability. Due to its design, such a lock can only be used for left- or right-hinged doors.

The invention is therefore based on the object of developing a generic lock in a manner which is advantageous in terms of use.

The object is achieved by the invention specified in claim 1.

Subclaims represent advantageous developments of the invention.

As a result of the configuration according to the invention, there is a lock, in particular an espagnolette lock, in which a left / right changeover is possible with simple means. Due to the mirror-symmetrical nut halves, either one, the other or both nut halves can be coupled to the trap. The coupling members are detachable and therefore relocatable or relocatable even after the lock has been manufactured, so that the coupling between the latch and the nut is adjustable. The case is preferably assigned an actuating section on the tail side. This actuating section can be designed as a projection. It is further preferred that a lock lever is assigned to the lock, which acts on this actuating section. In a preferred development of the invention it is provided that the nut actuation is locked when the bolt is locked. It is also conceivable instead of Nut to lock the relocability of the connecting rod connecting slide. For this purpose, a locking member projecting into the actuation path of the nut can be provided, which is assigned to a locking slide. The locking slide can be moved together with the bolt exclusion in the bolt pre-movement. The locking slide preferably has two fork-shaped locking prongs, each locking prong interacting with a locking projection of one of the two nut halves. Each nut preferably has an actuating arm. The two actuating arms should be spaced apart in the axial direction (pusher mandrel axis) so that there is a space between the two arms. The actuating section of the trap tail can protrude into this space when the nut is turned. The coupling member can either be assigned to the trap tail or to the nut arm. If the coupling member is assigned to the nut arm, it is preferably provided that it projects into the spacing space, so that when the nut rotates, the coupling member acts on the actuating section of the latch tail and thereby retracts the latch. If the coupling piece is assigned to the trap tail, it is preferably arranged in the region of the actuating section and projects in the axial direction into the movement path of one or both nut arms. Each nut half is preferably held individually in a spring-loaded central position. The sprung middle position can be maintained by a two-armed slide, as described in DE-OS 40 41 537 in detail. It is preferred that such a spring-loaded slide is provided twice, each slide acting separately on one of the two nut halves. Both nut halves each have a radial edge recess into which a tooth of a pivot lever projects. 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 clearance is also described in detail in OS 40 41 537 and is used for the nut to be returned to the neutral position after a drive rod shift either to the open or the locked position. A clearance is also provided between the two edge areas, to which the radial recess is assigned, into which a partial section of the pivot lever projects. Two teeth of the swivel lever protrude from this section in each case in the axial direction.

A further development of the invention provides that the coupling member is not assigned to the actuating arm of one of the two nut halves, but to the trap tail. The coupling member is preferably assigned to the actuating section of the latch tail and can be displaced in the transverse direction to the lock plane. The coupling member can be displaced by a spindle drive which is designed in the form of a screw which is rotatably arranged in the case tail. The spindle drive can be operated using a screwdriver. The spindle is mounted at its two ends in the actuating section, so that a narrow actuating member can be displaced in the transverse direction in an intermediate space such that it can be acted upon by an actuating arm of one nut half in one extreme position, but not by the other and in the other extreme position can be acted upon by the other nut half, in which case the other nut half is then exposed.

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

The lock according to the invention has a lock case which has a lock base 35 and a lock cover 34. At the front, the lock has a cuff which has openings through which a latch head 8, a latch 1 and a bolt 29 pass. A drive rod connecting slide 22 is guided along the cuff in the lock case. A swivel lever 19, which has a first arm in which a slot 20 is provided, is used to drive the connecting rod connecting slide. 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 about the axis of rotation 40, the connecting rod connecting slide 22 is displaced along the cuff. 1 shows the drive rod connecting slide position corresponding to the open position, and FIG. 2 shows a position of the drive rod connecting slide 22 assigned to the blocking position.

The pivot lever 19 has two axially opposite pins or teeth 18 which are separated from one another by a partial section 44. The two pins 18 protrude into a radial recess 17 of the two nut halves 5, 6. The radial recess 17 has such a circumferential angular width that each of the two nut halves 5, 6 is held in the neutral position, regardless of the position of the pivot lever 19 between its two end positions (Fig. 1, Fig. 2).

The neutral position of the two nut halves 5, 6 is maintained in each case by a spring-loaded slide 14, 36. The slide 14, 36 has two slide arms 15, which cooperate with drivers 16 of the nut. Regarding the interaction of sliders 14, 36 with the drivers 16 of the two nut halves, reference is made to OS 40 41 537.

A bolt 29 is provided in the lock housing, which can be locked and closed by actuating a profile lock cylinder. The locking cylinder has a locking member 31 which interacts with a tumbler 30. The arm of a change lever, which can be acted upon by the closing member 31, is mounted on the bolt. The second arm of the change 31 acts on an actuating section 7 of the latch tail 2 such that the latch 1 is withdrawn when the latch is actuated.

The espagnolette lock has two nut halves 5 and 6 lying one behind the other in the axial direction of the handle axis. The nut halves 5, 6 are symmetrical and each have an arm 10. The arms 10 are spaced apart at least in the region of their free ends. A space is formed between the latch arms, in which a stop 9 of the actuating section 7 of the latch 1 projects. Each of the two arms 10 has a bore into which a coupling pin can be inserted. 6, the coupling pin 11 is inserted into the right half of the nut 6 and in FIG. 7 the coupling pin 11 is inserted into the left half of the nut 5. Correspondingly, the latch retracts according to FIG. 6 when the lever 4 is actuated and according to FIG. 7 when the lever 3 is actuated Rotational entrainment can be rotated. Likewise, the two trigger mandrel sections 3, 4 can also be rotated against each other. The front ends of the two axially aligned mandrel sections 3, 4 are spaced apart. They lie in a blind bore 23 with a rectangular cross section of the respective nut halves 5, 6. A coupling pin 38 is provided which protrudes from one of the two end faces of the presser mandrel 4 and projects into the opposite end face of the presser mandrel section 3. The pin is designed so round that the two pushers 3, 4 can be rotated against each other.

The mutually mirror-symmetrical nut halves 5, 6 slide on one another with one of their end faces. Opposite the end faces, the nut halves 5, 6 have a cylindrical collar which lies in a corresponding opening in the lock cover 34 or lock base 35. It is provided that a coupling pin 11 can be inserted into both arms 10 of the two nut halves 5, 6. The coupling pin 11 extends up to the level of the joint of the two nut halves into the space. It projects in particular into the space between the two free ends of the arms 10. In the plane of the joint there is a section 9 of the trap which the releasable coupling member 11 acts upon when the nut is actuated.

Driver projections 16 are arranged on the end face of the nut 5, 6 opposite the joint, on each of which a prong 15, 37 of a slide 14 rests. The drivers 16 are arranged approximately diametrically opposite one another so that, depending on the direction of rotation of the nut, the slide is displaced along with a compression of the spring 32, 33. The two springs 32, 33 are aligned with each other in the lock case and act elastically on the slide 14, 36.

Opposite the slide, a locking slide 27 is arranged on the lock bottom 35 or under the lock cover 34. The locking slide 27 has two parallel tines 45, 46, each tine 45, 46 being provided with a locking lug 25 which interacts with a locking projection 26 of the nut. The locking lug 25 undermines the locking projection 26 when the slide 27 is displaced in the locking direction. As a result, the pusher 24 can no longer be pressed down in order to shift the drive rod into the open position. To take with the bolt lock, the locking slide 27 has a driver projection 28, which is acted upon by the locking of the bolt or by the bolt 29 itself, so that the locking lug 25 is displaced under the locking projection 26 when the bolt is locked and when the bolt 29 is moved back accordingly under the Locking projection 26 is moved away so that the nut can be rotated in this position. The swivel lever 19 lies between the two tines 45, 46.

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 push button 24 is released, the nut becomes again due to the spring-loaded slide 14 in the neutral position shown in Fig. 1. 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.

If, on the other hand, the opposite handle 3 is pivoted together with the nut 5, the actuating section 7 of the case is not carried along, since the nut arm 10 of the nut half 5 is not provided with a pin. From this lock side, the latch cannot be retracted by actuating the handle, but only by actuating the profile locking cylinder by means of a change operation via the change 13.

If, starting from the neutral position shown in FIG. 1, the pusher (outer pusher or inner pusher) is shifted upwards (FIG. 2), the pivoting lever 19 is carried along by acting on the tooth 18. The pivoting rod 19 becomes associated with this pivoting of the pivoting lever 19 - Connection slide 22 shifted upwards. The lock is now in the locked position shown in Fig. 2. If the handle is released in this position, one of the two nut halves 5, 6 is spring-loaded to the neutral position.

In the last-mentioned connecting rod connecting slide position (blocking position), the bolt 29 can be closed by actuating the profile locking cylinder (cf. FIG. 5). In this position, a locking slide is shifted - along with the locking bar - in such a way that a locking lug 25 of the locking slide 27 slides under a locking projection 26 of the nut half 5, 6, so that the pusher 24 can no longer be pressed down.

If the bolt is closed, the locking slide is also moved back, so that either the nut half 5 or the nut half 6 can be pivoted by actuating the inner or outer handle. Along with such a pivoting of one of the two nut halves 5 or 6 by pressing the pusher 24 down, the tooth 18 is acted on in the opposite direction, so that the pivot lever 19 is moved back into the neutral position shown in FIG. 1, accompanied by an opening displacement of the connecting rod connecting slide 22.

If the lock is to be changed from a left-hinged to a right-hinged door, the latch head 8 only needs to be turned through 180 °. For this purpose, a cylindrical latch tail 2 is provided, which is fastened to the latter with a screw 39 in a latch end piece which is formed by the actuating section 7. The loosening of the screw 39 enables the latch 8 to be turned over. In addition, the pin 11 must also be pulled out of the nut half 6 and (as shown in FIG. 7) inserted into the nut half 5. Then the nut half 6 is uncoupled from the trap.

In the exemplary embodiment shown in FIGS. 8 to 10, the coupling member 47 is assigned to the trap tail, namely the actuating section 107. For this purpose, the actuating section 107 has a U-shaped recess in which a plate lies, which can be acted upon by the latch arm 110 with an end region 47 '. The plate 47 has approximately a thickness that corresponds to half of the U-space. A screw 48 is clamped as a threaded spindle between the two U-legs. 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 projects. The screw 48 thus acts as a threaded spindle. By rotating the screw 48, the coupling member 47 can be displaced transversely to the lock extension plane, so that it can be acted upon either by the actuating arm 110 of the nut half 106 or by the actuating arm 110 'of the nut half 105. The other half of the nut is then released without the latch being actuated. As can be seen in FIG. 10, the nut halves are parallel to one another in such a way that the two actuating arms 110, 110 'are separated by a free space. 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 is immersed. The trap tail 102 continues towards the rear into an actuating section 107 which has the cutout in which the coupling member 47 can be displaced transversely.

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

All the features disclosed are essential to the invention. The disclosure content of the associated / attached priority documents (copy of the prior application) is hereby also included in full in the disclosure of the application, also for the purpose of features of these Include documents in claims of the present application.
