Abstract

The assembly has a sliding arrangement that is split into two parts (122, 124), and a motor actuating drive operating on the part (124). A manual drive operates on the part (122), which unavoidably moves with the part (124), during unlocking operation of the device. The part (122) is locked by cylinders. A joint (126) transfers the movement of the part (122) to the part (124), when a mechanical force is applied on the part (122).

Description

The present invention relates to a locking / gripping device for a gate, in particular a garage door or a door, which is protected in a special way against manipulation by unauthorized persons.

Out DE-PS 101 09 533 The same applicant is a locking / gripping device for a gate, in particular a garage door or a door, known, with which locking elements for the gate are blockable, releasable and driven to transfer the door from a locked state to an unlocked state and back again. Fig. 10 shows the device according to the aforementioned patent in a plan view, while Fig. 11 a sectional view of Fig. 10 is along a center line "L" therein, in which the device is shown in the installed state with a door leaf.

The locking / gripping device 2 is both manually and via a particular motorized actuator ver and unlocked and thus actuated, both the manual and the taking place via the actuator actuation operations act on a slide 12 whose movement into corresponding unlocking and locking operations be implemented by closing elements. For example, a stroke movement of the slider 12 by an amount "A" in Fig. 10 via a link arrangement within the slider 12 locking elements 32 laterally (ie in Fig. 11 from the plane of the drawing and into it) into the housing 4 (6, 8) or the gate assembly of the slider 12 is pulled by bolts 30 which are secured in the locking elements 32 by obliquely arranged recesses 28a in the manner of an inclined plane to be guided inside and the Take locking elements 32 with you. Alternatively or additionally, by means of bolts or stop plates 36 in recesses 38b of the slider 12 locking elements 34 are pulled upwards. The locking elements 32, 34 in Fig. 10 are metallic bands that are connected by other steel bands or cables with spring-loaded locking elements, which in turn engage in recesses laterally or below the door leaf and lock the door so.

As seen from the sectional view of Fig. 11 it can be seen, the slider 12 is divided into two parts, wherein the motorized actuator acts on a first part 24 of the slide, with which the locking and unlocking operations are feasible alone, and the manual drive acts on a second part 22, the first part 24 during unlocking necessarily moved by a contact point 26. The second, manually operated part 22 can be closed by a key 16 with a key 18, wherein, for example, the lock 16 locking elements (not shown) operated, which then enter into positive engagement with the housing 4 or parts thereof, so that the second , manually operated part 22 relative to the housing 4 fixed, that is fixed immovably.

In recent times, burglary protection for buildings has come more and more to the fore. Not only is the user increasingly seeking protection against unauthorized intrusion, but also certain requirements have been standardized for different burglary protection classes, which must be met in order to obtain a corresponding certificate. The various burglary protection classes are usually determined by the resistance to certain tools, the resistance in turn defined by the time is necessary to overcome the obstacle with the permitted tool.

As before, the locking system and the associated handle mechanism of a door or a door or a lock are a central point of attack for unauthorized intruders and therefore offer approaches to further improvements.

A popular method to overcome a locked mechanism is to overcome locking elements by large, possibly jerky force on the manually operated part. For example, in the device of FIGS. 10 . 11 by a large force, which is applied by means of leverage or with the aid of a jack on the recessed grip 20 of the second slide member 22, either the locking elements or the housing parts, which are provided for positive contact with the locking elements, be overcome, so that the sliding movement of the manually to be operated slide member 22 is no longer blocked. This would allow unhindered opening of the gate.

Another point of attack for locking / lock systems is the lock cylinder itself, which can be exposed so far even when flush installation of the same by mechanical lever tools that he can be gripped and removed with the help of a pair of pliers or the like. Thus, the locking mechanism is accessible from the outside and can be easily unlocked.

Due to structural conditions and design specifications, the lock and lock mechanism in a gate such as a ceiling sectional or Seitensektionaltor in most cases can not be performed as stable as an entrance door. Provided Therefore, a building that can be closed by a gate, additionally has an access option through an entrance door, it may prove advantageous in terms of burglar protection to dispense with the manual accessibility of the locking device from the outside. However, this may require a completely different design of the locking mechanism or at least the housing for receiving the same. Thus, two different models need to be designed, constructed, and stored for the two cases of an outside access or outside access application, which increases the cost of such a device. Therefore, door locks with an outboard part are often used in situations where it would not be necessary. This can provide a burglar with unnecessary starting points for unauthorized intrusion.

A main object of the present invention is to provide a locking / gripping device which has an improved resistance to unauthorized, in particular forcible intrusion in comparison with known devices. As a result, given the above considerations, the further object is to provide a locking / gripping device which has effective protection against forcible operation of a manual operating element.

This object is achieved by a locking / gripping device solved according to claim 1.

When the second part of the slide arrangement is shut off, the first part can continue to be movable via the actuator. Thus, it is not necessary to manually unlock the device prior to unlocking and opening the door via the actuator, which adds to the convenience of the device.

The junction between the manually operated second part and the first part is therefore constructive adjusted so that it yields earlier when mechanical force than the composite of - consisting of locking elements and their abutment - closing organs. This ensures that, when a large force is applied from the outside, the connection between the two parts of the slide assembly yields, with the result that although the second part can be operated manually from the outside, but this no longer entrains the first part , Thus, such an attack is in vain.

Preferably, the actuating direction of the first part of the slider assembly is substantially coincident with the opening direction of the door and the manual actuation of the second part by a handle portion which is actuated substantially in the opening direction of the door leaf, effected. If the direction of movement of the first part substantially coincides with the opening direction of the door leaf, the unlocking movement of this first part can easily be done manually from the inside in case of power failure by the first part is grasped by hand and pushed upwards, and with the same movement Gate to be opened manually. The same applies to a manual operation from the outside, when a handle part is provided for actuating the second part of the slider assembly, which is operable substantially in the opening direction of the door leaf.

Advantageous alternatives for the design of the handle part are a folding lever, a rotary handle or a linearly displaceable component. With a folding lever, the required forces for actuating the second part of the slide arrangement can be optimized by suitably designing the lever ratios. A rotary handle is advantageous in terms of a manual opening of the gate, especially for large, heavy goals, as a Rotary handle is particularly stable executable. The latter also applies to a linearly displaceable component as a handle part, which can also be designed so that it protrudes little to no over the outer contour of the door leaf and also an optionally existing lock cylinder can be accommodated in the linearly displaceable component, whereby - as it out The prior art is already known - the locking / gripping device can be secured against an opening with a stuck key.

It is particularly advantageous if the connection point has a predetermined breaking point, since then a defined, predictable fracture behavior is achieved and an expansion of damage into areas in which this is not desired can be avoided.

According to the invention, the first and the second part of a slide arrangement are structurally designed so that the directions of movement of the first and the second part are different from one another, in particular in opposite directions. When the first part of the slider assembly, which is responsible for the actual locking and unlocking of the locking elements, and the manually operated second part move manually in the same direction from the outside, it is conceivable that with sufficient knowledge of the geometry of the device a subsequent or additional connection between the two parts of the slider assembly is made, such as by additionally introduced from the outside bolts, screws or the like. Such a connection could - either alone or together with the not yet destroyed connection in the region of the junction between the two parts of the slider assembly - be strong enough to break the barrier assembly. In mutually different, especially opposing movements However, the first and the second part of the slide assembly would be a subsequent or additional connection of the first and the second part without success, because it would block any movement of these parts and the function of the locking mechanism as a whole.

The movement of the second part of the slide assembly can be transferred to the first part via a connecting element mounted in the first part or the second part, preferably a bolt or a plate. If the connection is realized in this way by a connecting element, this connecting element or its bearing points can give in excess of the force acting on the second part of the slider earlier than the locking compound. Thereby, the destructive effect can be limited to a small area. In particular, the connection may be designed so that the connecting element breaks off when excessive force is introduced or breaks out of its anchoring.

Preferably, the connecting element is mounted in the second part and acts on a lever arrangement, which in turn acts on the first part so that the direction of movement of the first part is different from that of the second part, in particular this opposite. When the connecting element is mounted in the second part of the slide arrangement, the destruction is limited to the connecting element or to the second part of the slide arrangement. Thus burglary attempt remains due to excessive force on the second part without affecting the first part, whereby the operation of the first part - for example by actuator - remains undisturbed. A lever arrangement is a particularly advantageous, because easy to implement, embodiment of the movement change or reversal between the first and second part of the slide assembly, the simple Way is customizable by design of leverage to specific requirements and structurally simple and robust feasible.

Preferably, the closing members include a blocking element which blocks in its blocking position movement of the connecting element at least in its actuation direction. If the blocking element acts directly on the connecting element, it can be ensured that it is broken off or broken down if excessive force is introduced.

Preferably, the first part of the slide assembly is manually operable from an inner side of the door leaf, in particular displaceable. If the first part, which is normally actuated by a motorized actuator, is also manually accessible from the inside, in the event of a power failure or control error, the door can be manually opened from the inside, thereby allowing a person to enter the space closed by the door is reduced.

The locking / gripping device may comprise a decoupling member for decoupling the motorized actuator from the gate, the decoupling member being manually operable from the inside of the door panel. By decoupling the motorized actuator manual opening of the door leaf is facilitated because you do not have to work against the braking effect of the engine.

Preferably, the decoupling component is forcibly actuated in a movement of the second part of the slider assembly in the actuating direction, in particular by the connecting element. Thus, the above mentioned effects even with manual operation from the outside.

Hereinafter, various aspects of the background of the invention and embodiments of the invention will be described. In the embodiments, the invention is embodied in a locking / gripping device for a ceiling sectional door. The invention can also be applied to a closing system for a side sectional door, a swing or pivot or a sliding or swinging door. The directional indications "inside", "outside", "above" and "below" refer to the door leaf of such a ceiling section door.

Fig. 1 shows a first aspect of the background of the present invention. The first aspect is a further development of the locking system of the prior art. The basic structure and the operation correspond to those of the locking / gripping device after the German Patent 101 09 533 ,
In this locking / gripping device, which is also referred to below as simplifying as "locking system" is a mechanically or motor-operated first part 124 of a slider coupled with a manually operable second part 122 that upon actuation of the second part 122 of the first part 124 is entrained, while upon actuation of the first part 124 by a servomotor, the second part 122 remains unaffected. The second part 122 can be blocked by means of a cylinder 116. In the locked state of the cylinder 116 while the movement of the manually operated part 122 is blocked relative to the housing 104 via suitable strike plates and stop points. In that regard, the structure and operation of the locking system of the first aspect are consistent with those of the prior art locking system.

In the first aspect of the background of the invention, the connection between the second part 122 and the first part 124 is designed so that this connection breaks with manual operation of the second part 122 with increasing force before the bond between the strike plates and stop points can yield. This is accomplished for example by a suitable shaping, such as a correspondingly designed wall thickness of the first part 124 at the point 126, in the form of a predetermined breaking point. But it would also be sufficient to make the wall thickness of the first part 124 at all so that a weakening compared to the composite of the closing elements is present.

In a variant of the first aspect, in Fig. 2 is shown, the connection between the second part 122 and the first part 124 may be embodied by a connecting bolt 127 which is seated in a corresponding bore in the upper region of the first part 124 and the excessively large force from the second part 122 from the bore breaks out before the bond between the strike plates and stop points can yield. In another variant, the in Fig. 3 is shown, the connecting pin 127 is seated in a corresponding bore in the lower region of the second part 122nd

In the closure device of the first aspect, the closure bond between striking plates and stop points or the like can not be overcome. Rather, a connection with which an upward movement of the second part 122 is transmitted to the machine-actuated part 24, after earlier. This will be the second part 122 is freely movable, without any effect on the position of the first part 124. Thus, over the second part 122, the gate can not be unlocked.

Instead of the connecting bolt 127, a connecting plate may be provided, which breaks off or breaks down with a large force. Such a design facilitates the repair after an unsuccessful break-in attempt.

Hereinafter, with reference to FIGS FIGS. 4A to 9B an embodiment of the invention will be described. The embodiment is the preferred embodiment of a locking / gripping device of the present invention and, at the same time, the best mode for carrying out the invention. The locking / gripping device of this embodiment is also referred to simply as a "locking system".

The locking system of the embodiment is constructed as follows. In a housing cover or inner frame 200, which is to be fastened in a suitable manner on the inner wall of a segment of a door leaf (not shown in detail), a carriage 400 is displaceably guided. The inner frame 200 and the carriage 400 are respectively formed by punching and bending sheet metal parts, e.g. made of sheet steel.

The carriage 400 is in the form of a base plate 410 with a cranked ledge or ledge 420 on its lower side and two left and right upwardly extending arms 430, 440. (Hereinafter, the directions "left" and "right" refer to the representation in the FIGS. 7A and 7B , ie on the locking system seen from the inside of the gate. The Direction information "front" and "back" or "before" and "behind" also refer to the representation in the FIGS. 7A and 7B .)

The heel 420 has a vertical leg 422 which is bent at right angles from the base plate 410 forward, and a parallel leg 426 which is bent from the vertical leg 422 down at right angles, ie the base plate 410 in one extended to this parallel plane down. In a region of two holes 428 provided on the left and right in parallel legs 426 of paragraph 420, the parallel leg 426 is doubled by two tabs 424 punched out of the vertical leg 422 of the shoulder 420 and bent in the direction of the parallel leg 426. The holes 428 also extend through the tabs 424. Between the parallel leg 426 and the tabs 424 a certain distance is provided. Furthermore, in the vertical leg 422, a further bore 425 is introduced in each case in the middle between one of the lugs 424. The tabs 424 and the holes 428, 425 are used for attachment of cables, steel bands or the like (not shown in detail), which - possibly via suitable deflections - lead to locking elements such as sprung Schnäppern or the like. The locking elements engage corresponding counter openings in the frame or the threshold of the door opening to prevent movement of the door with respect to the door opening.

From the upper end of the base plate 410 extend in the extension of the same two arms 430 and 440 upwards, which are also part of the carriage 400. The in Fig. 7 left arm 440 (hereinafter also referred to as a support arm or blocking arm 440) has at its upper end a vertical bend 442 on. The task and operation of the blocking arm or the bend will be described later.

The in FIGS. 7A . 7B Right arm 430 (hereinafter also referred to as a pull arm 430) terminates at the top in a cranked end 432, as best seen in FIG Fig. 1 can be seen, which is doubled by a tab 434 in parallel with a certain distance and through which a vertical bore 436 extends. The doubled end 432, 434 with the bore 436 serves to attach a cable, steel strip or the like (not shown in detail), which - possibly via suitable deflections - leads to a servo motor. By the operation of the servomotor, which pulls the carriage 400 on the cable upwards, and the cables which are attached to the lower end of the carriage 400, so the locking elements can be solved.

The servomotor is usually identical to the motor for the door leaf. It is provided by suitable means, such as a slot recess between the drive and the relevant point of articulation on the door leaf, for the drive on the door leaf a certain empty or lost motion, while the cable for pulling the carriage 400 is directly connected to the drive in operative connection. When you lower the door leaf, the carriage 400 is above the cable of the motor initially in its pulled-up position and, when the motor in the lower end position of the door leaf performs the backlash in the slot and gradually releases the carriage 400, by the spring action of Pull locking elements down until the locking elements reach their locked end position.

The shape of the inner frame 200 is essentially determined by a bottom plate 210 whose lateral edges are bent twice by 90 ° to form respective left and right folds, each consisting of a vertical folding leg 220a, 220b and a parallel folding leg 230a, 230b exists. In the folding legs in each case a cross-section roughly U-shaped sliding bar 300 is used, which form the guide for the carriage 400.

The parallel folding legs 230b of the in the FIGS. 7A . 7B Right fold has a nose 232 bent away in the direction away from the plane of the bottom plate 210 with a vertical bore 234. In the bore 233, a lever 310 is mounted at one end thereof. The lever 310 is designed as a sheet metal part in punching / bending technique, which has for the purpose of storage at the corresponding end a doubled by bending a tab 311 by 180 ° and a vertical through hole 312. The lever 310 extends from its bearing point in the nose 232 of the inner frame 200 to the left across the entire width of the inner frame 200 and beyond. The lever 310 has two further through-holes 313, 314. These serve on the one hand as an attachment point for a spring (not shown in detail), the lever with respect to its bearing point in a clockwise direction (in FIGS. 7A . 7B ) and for this purpose is fastened with its other end at a suitable point on the inner frame 200, and on the other hand for attachment of a cable, steel strip or the like (not shown in detail), which leads to the door drive and the decoupling thereof from the door leaf is used , To decouple the door drive of the door leaf of the lever 310 from its substantially horizontal normal position counterclockwise, so at its left end down to actuate. Also in the area of the holes 313, 314, the lever 310 is executed doubled.

The left fold of the inner frame 200 or its parallel leg 230a is provided with a bent by 90 ° from the plane of the base plate 210 first extension 234 having a longitudinally extending in the vertical direction slot 235. The slot 235 is provided for receiving the left end of the lever 310 and is designed so that it gives the standing in its horizontal normal position lever 310 an end stop upwards. From there, the slot 235 extends downwardly so far as to give the lever 310 an end stop down so that it (the lever 310) can be deflected so far down (counterclockwise) that in the deflected position the door drive is decoupled.

With this arrangement, it is also possible to manually open the door from the inside, by on the one hand the lever 310, seen from a user located on the inside of the gate (as in FIGS. 7A . 7B ) is projected laterally to the left from the inner frame 200, is operated down to decouple the door drive, and on the other hand, the carriage is pulled up to unlock the gate and push upwards. For ease of handling, better ergonomics, prevention of injury and more pleasing design, a cover or panel (not shown in detail) may be provided covering the entire complex of the inner frame 200 and the carriage 400 so that the carriage 400 may be suitably designed Grip - can be taken from below and the lever 310 protrudes laterally from the cover and is operable.

In the arrangement described so far, the door can be manually unlocked and raised in addition to the motor actuation only from the inside. An external operation is therefore not possible. A separate from the above-described arrangement, but connectable with this and can be mounted together on the door leaf second part also allows manual unlocking and raising the gate and a locking of the locking mechanism from outside the gate. This part will be described below.

A lock housing 500 is made of a sheet metal part in stamping / bending technology and consists essentially of a connecting plate 510, protruding from the level of a cuboid lock box 520. The lock housing 500 is installed in the installed state that the connecting plate 510 between the inner frame 200 and its bottom plate 210 and the wall of the door leaf (not shown) is applied and is fastened together with the inner frame 200 from the inside to the door leaf, while the lock box 520 extends through a recess in the door leaf adapted to the lock box 520 in its dimensions. The connecting plate 510 has lateral bends 512a, 512b, which include the inner frame 200 left and right. The connection plate 510 also has six vertical bores 514, which are aligned with six vertical bores 212 of the bottom plate 210 of the inner frame 200 in assembly.

With this arrangement or design, it is possible to use the lock housing 500 with its lock case 520 including internals (described below) in the recess in the door leaf, whereby its position is substantially fixed. Then, the inner frame 200 inserted between the two bends 512a, 512b be, whereby the inner frame 200 is supported in the lateral direction and angular position. By vertical displacement of the inner frame 200, the bores 212 can then be brought into alignment with the bores 514 and fastened to the door leaf by means of suitable fastening means, such as bolts or screws.

Fig. 8A and 8B show a vertical section of the device of Fig. 7A or 7B along a line AB or GH, ie along the vertical center plane of the device, while FIGS. 9A and 9B a laterally offset vertical section of the same device along a line CD or EF in Fig. 7A or 7B show. In these sectional views, the parts of a manual operating device 600 and a closing device 700 arranged in or on the lock case 520 can be seen particularly clearly.

On the lock case 520 a folding handle 620 is rotatably supported via a bearing 610, wherein the rotation axis 626 is outside the lock case 520 and extending parallel to the wall plane of the door leaf in the horizontal direction. The folding handle 620 has an actuating arm 622 and two push arms 624, the latter, like tines of a two-pronged fork, pointing away from the former at a suitable angle. Here, the push arms 624 are bent into the lock case 420 and have a rounded end. The lock case 520 and the folding handle 620 are hidden except for the operating arm 622 and an opening for a key 715 of a shutter 800. In the non-actuated state, the actuating arm snuggles into a corresponding receiving opening in the aperture 800 and protrudes from the axis of rotation 626 substantially vertically downwards, while the push arms 624 extend into the interior of the lock case 520 inside.

Inside the lock case 520, the two push arms 624 of the folding handle 620 rest on an inner slide 630 from above. The inner slide 630 is arranged vertically displaceable within the lock case 520 and by means of suitable spring elements (in the FIGS. 8A . 9A . 9B If a spring holder 730 is shown for this purpose) is biased upward. By means of the spring preload, the folding handle is also urged into its non-actuated position by means of the contact between the inner slider 630 and the pressing arms 624 (in the counterclockwise direction in FIG FIGS. 5A . 6A ).

To actuate the folding handle 620 whose operating arm 622 is initially engaged behind from the outside. For this purpose, the aperture 800 is provided with a bulge 810, which extends below the lock case 520 in a corresponding recess in the door leaf (not shown in detail). By pulling the actuating arm 622 outwardly and upwardly, the folding handle 620 is rotated (clockwise in FIG FIGS. 5B . 6B ) or folded out of the aperture 800. As a result, press the two push arms 624a, 624b from above on the inner slide 630 and move it against the spring force down.

The downward movement of the inner slider 620 is translated via a lever mechanism 640 in an upward movement of the carriage 400, as described below and best of the FIGS. 5A and 5B seen.

At two bearing points 240, which rise from the bottom plate 210 of the inner frame 200, 642 two release lever 644 are rotatably supported by means of corresponding bearing pin. The release lever 644 cross each other in the horizontal center of the inner frame and can in this position (center position) to each other swing over. To achieve this, the bearing points 240 are raised to different heights by the thickness of the identical release lever 644. The unlocking levers 644 have on their pointing towards the middle arm (hereinafter referred to as "bound arms") 646 long holes 647, which lie in the middle position of the two release levers 644 so one above the other, that of their respective pivot-side curves formed vertical channel through the two release levers essentially corresponds to a circular opening with the diameter of the width of the slots 647 or a slightly larger slot of the same width so that they provide a connecting bolt 650 space extending through the two slots and in a blind hole 632 at the lower end of the inner slider 630th is clamped.

Each unlatching lever 644 also has an outer arm (hereinafter referred to as "free arm") 648 which faces away from the center and which is each cranked away from the plane of the bottom plate 210 and each received in a bore has a follower pin 660 extending therefrom respective release lever 644 from in the direction of the bottom plate 210 and the carriage 400 shows. The drive pins 660 abut respectively on the underside of a stop bracket 450, which rise in the form of from suitable portions of the base plate 410 or the Zugarms 430 and the blocking arm 440 of the carriage 400 punched out and bent tabs.

As described above, the connecting bolt 650, which is clamped in the blind hole 632 of the inner slide 630, projects through the two slots 647 of the two unlocking levers 644 (see also FIGS Fig. 8B ). In the locking position, the inner slide 630 are in its upper end position and the Carriage 400 in its lower end position, while the two bounded arms 646 of the release lever 644 are held by the locking pin in its respective upper end position and attached in the two free arms 648 of the release lever 644 Mitnehmerbolzen 660 abut from below against the stop blocks 450 of the carriage 400 (please refer FIGS. 5A . 7A )

If the folding handle 620 is actuated and the inner slider 630 is thereby pressed down, the bounded arms 646 of the two unlocking levers 644 are pressed downwards by the connecting bolt 650 guided in their oblong holes 647 and the unlocking levers 644 are thereby rotated about their axis of rotation into the bearing pin 642, whereby the free arms 648 of the release levers 644 move upwards and push the carriage 400 upwards via the driving pins 660 and the stop blocks 450 fastened therein (see FIG FIGS. 5B . 7B ). As a result, as with the mechanical operation via cable or steel bands (not shown), which are secured in the holes 428 of paragraph 420, unlocked with the carriage 400 in the train compound locking elements and released the door leaf.

At the same time pushes the follower pin 650, which protrudes a little way beyond the two release levers 644, the lever 310, which has an upward protruding shoulder 316 for this purpose, down, whereby the servomotor is decoupled in the manner described above from the door leaf.

It should be noted that when machine unlocked via the actuator, the entire arrangement of the manual actuator 600 for manual unlocking remains unaffected. If namely at machine Unlocking of the carriage 400 is pulled up by the motor force, the two stop blocks 450 of the carriage 400 lift off from the driving pins 660, and the carriage 400 slides freely upwards. The release lever 644 remain in its position by the action of the spring force pushing the inner slide 630 in the lock case 520 upwards and by means of the connecting bolt 650 on the slots 647 of the release lever 644 is transferred to the latter.

The locking device is also equipped with a locking device 700, which will be described below.

In the lock case 520, a receptacle or an adapter 720 is arranged, which receives a cylinder 710 commercially available, as it is manufactured by the companies Hahn, Kaba and Assa. The adapter 720 has a receptacle adapted to a particular type of cylinder. On a mounting plate 740 fixed to the inner frame 200, a locking lever 760 is rotatably supported in a plane parallel to the bottom plate 210 of the inner frame 200. The locking lever 760 has a fork extension 762 which protrudes into the adapter 720 such that it is rotatable by a locking lug (not shown in detail) of the cylinder 710 in each case by a certain angular amount in the counterclockwise direction. The respective end positions of the rotational movement of the locking lever 760 define a locked state or an unlocked state thereof. Two stop tabs 742 projecting from the mounting plate 740 additionally prevent the locking lever 760 from being overdriven beyond its respective end positions. The locking lever 760 also has a hook extension 764, which in the locked state, the connecting pin 650 so engages that the latter in its downward movement is prevented, however, releases the connecting bolt 650 in the unlocked state.

It should be noted that the closing device 700 relates only to the manual part of the locking device, that is, the manual operating device 600. Therefore, as will be understood from the above, the automatic unlocking by the servo motor is operable regardless of the lock or unlock state of the shutter 700.

In the locked state of the closing device or in particular of the cylinder 710 and the locking lever 760, the inner slide 630 is blocked by the connecting bolt 650 in its downward movement, so that the folding handle 620 can not be operated under normal force. To protect against excessive force on the mechanism, the connection between the inner slider 630, the connecting pin 650 and the locking lever 760 is designed so that the blind hole 632 breaks upon violent operation of the inner slider 630 before the resistance of the locking lever 760 can be overcome. As a result, although the inner slide 630 can then be pressed down by actuation of the folding handle 620, because of the lack of connection to the unlocking levers 644 and thus to the carriage 400, unlocking of the door is no longer possible.

The opposite directions of movement of the inner slider 630 and the carriage 400 provide a further improvement of the burglary protection. Was there conceivable, by introducing bolts or screws into the walls of the manually operated part 122 and the machine-operated part 124 to make a subsequent connection between the two parts 122 and 124 to to strengthen the weakened due to the breaking point or suitable design connection between these two parts and so as to overcome the resistance of the closing elements, it would be in the locking system of the inventive embodiment because of the opposite directions of movement of the manually operated part (inner slide 630) and the machine to be operated part (carriage 400) pointless to make such a connection between them, since they would then block each other.

As described above, the cylinder 710 is received in an adapter 720, which in turn sits in the lock case 520. The adapter 720 has on the side facing the door leaf on a nose 722, which projects through corresponding openings in the bottom plate 210 of the inner frame 200 and in the mounting plate 740 and is held by these. On the outwardly facing side of the adapter is held by suitable means. In this way, the adapter is held securely in place within the lock case 520. The connection between the cylinder and the adapter 720 is usually by frictional engagement (such as by pressing) or by screw connection and is designed to be stronger than the seat of the adapter 720 in the lock case 520 or at least as the seat of the nose 722 in the opening of the mounting plate 740 and the opening 794 of the safety slide 780.

The mounting plate 740 has on its left side a side web 744 with a vertical slot (see FIGS. 5A . 7A ). Furthermore, the left parallel folding leg 230 a of the inner frame 200 at the level of the mounting plate 740 has a perpendicularly bent away from the plane of the bottom plate 210 of the inner frame 200 extension (second extension) 236, which also has a vertical slot has. In the two slots in the side web 744 of the mounting plate 740 and the extension 236 of the inner frame 200, a safety slide 780 is mounted laterally displaceable. The safety slide 780 is cranked so that the left end 782, which is journalled in the slot of the extension 236, is farther from the plane of the bottom plate 210 than the right end 792, which is journalled in the side bridge 744 and flat on the raised one Middle part 746 of the mounting plate 740 rests. In its right end position of the safety slide 780 is located with the crank 784 on the side bar 744, while in its left end position by means of a shoulder 786 rests against the extension 236.

The left end 782 of the safety slide 780 also has a blocking web 788 (FIG. Fig. 7A ), which points in the direction of the door leaf. When the safety pusher 780 is in the left end position, the blocking ridge 788 is above the bend 442 of the blocking arm 440 of the carriage 400 in its path so that the bend 442 abuts against the blocking ridge 788 from below as the carriage 400 rises emotional. Thereby, a movement of the carriage 400 is inhibited upwards, and unlocking the door is no longer possible. On the other hand, if the securing slide 780 is in its right end position, the bend 442 slides unhindered past the blocking web 788 during an upward movement of the carriage 400.

An extended portion 724 of the nose 722 of the adapter 720 also extends through a corresponding opening 794 of the right-hand portion 792 of the locking plate 780 resting flat on the raised central portion 746 of the mounting plate 740 and also serves as a lateral abutment for one adjacent the opening 794 vertically away from the plane of the mounting plate 740 bent support tabs 796 of the safety slide 780. By the force of a spring (not shown in detail) is the safety slide 780 to the left in Fig. 7A biased, whereby the support tab 784 in the right end position of the safety slide 780 laterally against the extended portion 724 of the nose 722.

The right end position, in which the safety slide 780 rests with a stop tab 784 on the extended portion 724 of the nose 722 of the adapter 720, is the normal position or biased position of the safety slide 780. When the adapter 720 is removed from its position, the stop tab 784 slips of the safety slide 780 of the extended portion 724 of the nose 722 of the adapter 720, whereby the safety slide 780 quick by the action of the spring in its left end position. This position is also referred to as the triggered position of the safety slide 780. As described above, in the deployed position of the safety slide 780, the blocking ridge 788 blocks the upward movement of the carriage 740 via the bend 442.

The safety slide 780 therefore serves to ward off manipulation of the cylinder 710 itself. Burglars often try to pull the cylinder of a locking system to pass through the resulting cavity to the lying inside the system closing elements and to manipulate them. However, in the latching system of this embodiment, the cylinder 710 is seated in the adapter 720, and this connection is stronger than the retention of the tab 722 in the openings of the mounting plate 740 and the safety pusher 780. Thus, if a burglar attempts to pull or lever the cylinder 710, is inevitably the nose 722 or at least its extended part 724 pulled out of the opening, the Support tabs 796 of the safety slide 780 jump away from the extended portion 724 of the nose 722, the safety slide 780 springs into its released position by the spring action and blocks the upward movement of the slide 400. Therefore, even if the burglar succeeded in removing the adapter with the cylinder and to manipulate the locking lever from the outside, the entire mechanism would be blocked and the gate could not be unlocked.

The adapter 720 is manufactured with the same external dimensions but different cut-outs for different cylinder types. Thus, an easy replacement of the cylinder is possible with minimal effort. It is also possible to give the intermediate dealer or end user a set of adapters, into which he can then install a lock cylinder of his choice.

As can be seen from the above, the carriage 400 is the first motor-operated part and the inner slider 630 is the second, manually-operated part of a slider assembly as defined in the appended claims. The locking lever 760 is a blocking element, the connecting bolt 650 a connecting element in the sense of the appended claims.

In the foregoing, the best mode for carrying out the present invention has been described with reference to a preferred embodiment.

The folding handle can be replaced by a push handle or a rotary handle, which can act on the inner slider, for example via a gate / lever mechanism or an eccentric cam.

The leverage ratios and geometric relationships shown in the drawings are illustrative and are in no way intended to limit the inventive content of this application to these.

Also, the application of a Seitensektionaltor, a swing gate or a hinged door or a revolving door may result in special constraints on the kinematics of the locking system, such as due to a 90 ° twisted installation of the locking / gripping device.

As with the prior art locking system, the two-part slide arrangement allows the locking system to be selectively operated by hand or with motor power so that manual locking and unlocking in the event of regular motor drive of the door can be manually canceled in an emergency, for example in case of power failure or the like to open or close the gate despite the no longer functioning motorized actuator.

1. (1) Wegen der gegenüber einem Schließverbund vergleichsweise schwach - etwa in Form einer Sollbruchstelle - ausgelegten Verbindungsstelle zwischen dem manuell zu betätigenden Teil und dem motorisch angetriebenen Teil der Schieberanordnung kann der Schließverbund nicht durch übergroße Krafteinleitung in den manuell zu betätigenden Teil überwunden werden. Über einen Hebel kann bei manueller Betätigung der Stellantrieb von dem Torblatt entkoppelt werden, so daß das Torblatt nicht gegen die Bremskraft des Motors bewegt werden muß.
2. (2) Aufgrund der gegenläufigen Bewegungsrichtungen der beiden Teile der Schieberanordnung vermindert selbst das Einbringen einer nachträglichen Verbindung zwischen diesen Teilen den gemäß (1) dargestellten Einbruchschutz nicht.

The locking / gripping device of the present invention collectively has the following additional advantages.

1. (1) Because of the relative to a locking compound comparatively weak - designed in the form of a predetermined breaking point - joint between the manual to actuated part and the motor-driven part of the slide assembly, the locking assembly can not be overcome by excessive force into the manually operated part. By means of a lever, the actuator can be decoupled from the door leaf during manual actuation, so that the door leaf does not have to be moved against the braking force of the motor.
2. (2) Due to the opposite directions of movement of the two parts of the slider assembly even the introduction of a subsequent connection between these parts does not reduce the burglary protection shown in (1).

By using an adapter to hold the lock cylinder, the locking system can be easily and inexpensively converted to a different type of cylinder.

By an additional securing component, which blocks the movement of the entire unlocking mechanism upon removal of the adapter, and by the loose installation of the adapter in the locking system compared to the connection of the cylinder in the adapter, an attack against the cylinder itself runs into the void.

1. a) nur Handbetätigung von innen und/oder außen;
2. b) nur motorischer Antrieb mit/ohne zusätzlicher Möglichkeit der Handbetätigung von innen;
3. c) motorischer Antrieb mit zusätzlicher Handbetätigung von innen und außen.

By simply omitting parts, a simple and inexpensive conversion of the locking system between the following execution modes is possible:

1. a) only manual operation from inside and / or outside;
2. b) only motorized drive with / without additional possibility of manual operation from the inside;
3. c) motor drive with additional manual operation from inside and outside.

For example, a retrofitting from manual operation to motor operation is readily possible.
