Furthermore, reference is made to DE 40 13 439 A1 and to DE 202 11 508 U 1. In the prior art, it is possible to leave the pivot lever in the open state and nevertheless extract the cylinder key from the lock cylinders. However, there are applications where this is not desirable, but it should be ensured that the cylinder keys are removable only when the pivot lever has reached its pivoted locked position.

Object of the invention

The object of the invention is to provide an actuator of the type mentioned, which is suitable for these applications.

solutions

This object is achieved according to the invention in that upon actuation of the type mentioned a second locking element is provided which allows a return of the thumb in the position in which the key can be removed, only after pivoting back and folding the hand lever.

According to one embodiment of the invention, the second locking element is a slide extending within the trough, one end of which engages in a first push position hinged to the hinge shaft hand lever engages in such a way that it locks in the pivoted position, while the other end a return the thumb in the position causes or allows in which the key is removable, in a second thrust position in which the hand lever is released, however, prevents the return of the thumb. (Claim 2).

According to one embodiment of the invention, the slider comprises two interconnected parts which are coupled together via a freewheel gear in such a way that they move with delay in the same direction. (Claim 3).

According to yet another embodiment of the invention, the slider comprises two mutually displaceable parts, which are coupled together via a gear transmission (pinion meshes with racks) or lever system such that they move in opposite directions. (Claim 4).

The first and the second blocking element can therefore be formed or carried by the same slider.

However, the second locking element may also comprise a cylinder or sleeve enclosing the cylinder, with lateral recesses for play-free recording of the cylinder thumb and the slider end and for receiving the flat part of the lock cylinder with such play, the rotation of the cup coaxial with the lock cylinder with the rotation of the Thumb is possible. (Claim 6).

The cup bottom may according to claim 7 have a projection which engages with a slot formed by the slider end, such that a rotation of the key of one or the other cylinder and thus the associated thumb is in the unlocked position only possible when the slider is in the locked position, in which the other slider end blocks the lever folding and -drehlager.

The second locking element is provided by a slider with a hook for grasping the hand lever in the folded position and having a lug which is slidably received in a slot formed by the first slider and which is slidable between two end positions with respect to the first slider against spring force Such that play for engaging behind the hook remains formed by a hand lever return and is taken when moving the first slider in the unlocked position of the second slider until the hook is released. (Claim 8).

Detailed description of the invention Fig. 1A in a side view a Doppelzyliηderschwenkhebelätigung 10 for a latch and / or bar closure for mounting on a thin wall 14, such as metal door or the like., With a trough-like base plate 16 with two door leaf 14 piercing approaches 18, 20, wherein the one Approach 18 for connecting a shutter drive 12 or for an articulation shaft 22 for a hand lever 24 which can be folded out of the base plate 16 and then pivoted, and wherein the other projection 20 has a recess 26 for receiving a double cylinder device 28 holding the hand lever 24 in its folded-in position, whose two thumbs 30, 32 each act on a blocking element 34 in such a way that either one of the two cylinder locks 36, 38, the blocking element 34 can be released from its the lever 24 in its retracted position locking position. According to the invention, a second locking element 40 is now provided, which allows a return of the thumb 30, 32 in the position in which the key can be removed only after pivoting back and folding the hand lever 24.

As is apparent from FIGS. 1 A to 1 E and from the further FIGS. 1 F to 1 M, the second blocking element 40 is a slide 42 extending within the depression 16, which in a first push position, FIG Hand lever 24 hinged to the articulation shaft 22 engages such that it is locked in the pivoted position, while the other end 46 causes or enables return of the thumb to the position in which the key is removable. Fig. 1D shows in a second thrust position, in which the hand lever 24 is released, however, the return of the thumb 30, 32 is prevented.

In the embodiment shown in FIGS. 1A to 1 M, the release of the hand lever by displacement of a hook, which is designated in Fig. 1 D 34. In the same direction, the release is effected by the slider 42, but the hook 34, which is attached to a separate slider 48, is taken along by the first slider 42 when it is pushed to the right due to the cylinder movement of the thumb 32, 30, seen 1 D. By the game, which is guided by a slot arrangement 50, in which a projection 52 of the hook 34, is achieved that upon movement of the slider 42 to the right due to actuation of at least one of the locks 36, 38 and entrainment of the slider 40, an end 44 of the slider from the region of the shaft of the linkage 54 of the hand lever 24 on the shaft 22 causes the lever to swing out is prevented. Therefore, by first pulling the end 40 out of the spherical articulation area 54 of the hand lever 24, this hand lever 24 is released, and only after passing through the freewheel the hook 34 is pushed far enough to the right that the hand lever 24 is released at its free end. Conversely, it is prevented that the pusher plate 42 is pushed back, as long as the hand lever is not in its closed position, because otherwise there is no space that receives the end 44 of the hand lever 54, which is the case only in closed position hand levers.

Conversely, should the attempt to extract the key from the cylinder 38, 36, be successful, this cylinder must first be brought with his thumb in the closed position, which is the recognizable in Fig. 1E position. A compression spring 62 pushes the slider 48 with its projection 52 against the end 66 of the slot 60 and pushes the slider 42 with its tip 44 against the surface 64 of the hand lever 24, which only works when the lever 24 is folded. During this freewheel the division of the slider is required in a first and a second locking element.

Turning the direction of the hook 34 by 180 °, see the embodiment in Figs. 2A to 2M, it is necessary to form the slide of two mutually displaceable parts 142, 148, both by means of gear transmission (pinion 68 meshes with racks 70, 72) or lever system are coupled together so that they move in opposite directions.

On the other hand, in Figs. 1A to 1M, there is described a double-cylinder swing lever lock having a slider composed of second sliding parts 44, 48 having a slot driving gear 50, 52 so as to move in the same directions with play , In contrast, at Embodiment according to FIG. 2A to 2M realized a double cylinder pivot lever closure, wherein the slider comprises two mutually displaceable parts 142, 148 which are coupled together via a gear transmission (pinion mesh with racks) or lever system such that they move in opposite directions.

The second locking element 40, 140 is formed in the first embodiment according to FIG. 1 A to 1 M expediently by a cylinder which is surrounded by a sleeve or a cup, see reference numeral 54, with lateral recesses 58 for play-free receiving the cylinder thumb 60th and provided for entrainment of the end of the slider 42.

In the embodiment according to FIGS. 2A to 2M, the second blocking element 140 comprises a rack 134 provided with a slide 134 which is directly carried along by the thumb 160 of the cylinder lock 136, not via a cup 34, as in the first embodiment. The rack 70 meshes with a pinion 68 which is rotatably mounted in the hand lever, and the rack 72 of the slider 142 meshes with the pinion 68, such that the slider 142 performs a counter-rotating movement, d. That is, when the hook 134 is retracted, the slider 142 is also retracted, releasing the link shaft 122, so that the lever can be swung out. In this position, the key is not deductible. The thumb 160 can only be moved from its closed position, in which the key is removable, see Fig. 2L, in its open position, in which it is not removable, Fig. 2J, when the hand lever is in the folded position, because only then the opening of the articulation shaft 122 is aligned to receive the pin 76 carried by the end 144 of the slider 142, so that the sliding action can actually be performed, assisted by the compression spring 162.

As shown in Fig. 2K, the hand lever 124 is pivoted out of its folded position and also rotated, so that the slider 142 can not be inserted through the spring 162 in the opening 74, which means that the Thumb 160 of the cylinder closure 136 in its closed position in which the key 90 can not be withdrawn remains. The same applies to the cylinder lock 138, which is shown in Fig. 2K.

While the pivot shaft 22 in the embodiments of FIG. 1 A to 1 M drives a lock case with locking rods, as can be seen in Fig. 1 F, wherein the lock case bearing the reference numeral 78 is in the second embodiment of FIG. 2A still a Latch 82 available, which serves as a rotary latch in the height of the lock case z. B. can lock a door in a door frame.

In the first embodiment, the two optionally attachable cylinder locks are protected by separate cover plates 84, 86 against dust, while in the embodiment of FIGS. 2A to 2M provided for both cylinder lock openings common cover 184 is arranged. This can be pivoted about the linkage 88 in the clockwise direction or in the counterclockwise direction so that either the one key end 136 or the other end of the closure 138 is exposed and can be made available for the one key 90. Another difference between the two embodiments lies in the fact that in the embodiment according to FIGS. 1A to 1M the hand lever 24 only comprises the hollow gripping surface for the hook 94, while in the embodiment according to FIGS. 2A to 2M in the hand lever end the cylinder locks are arranged.
