Description

 TECHNICAL FIELD OF THE INVENTION

The invention relates to a multi-part locking system for sliding doors and a sliding door system with such a locking system.

 BACKGROUND OF THE INVENTION

In the field of the invention a variety of multi-part locking devices and security systems are known to lock sliding doors in a closed position.

The known devices and systems can roughly be distinguished by whether they prevent the movement of a sliding door panel by connecting it to the floor, connecting it to a fixed or counter-rotating sliding door leaf, obstructing the sliding door panel or blocking the drive of the sliding door panel. Thus, it is known to secure sliding doors that have a floor guide by inserting a rod in the floor guide against simply pushing. Such blocking is not closing the door in the true sense, since no key is necessary to remove the object blocking the route. In addition, the door is thus secured only in one dimension, namely against sliding.

For locking sliding doors floor locks are known in which by means of a key, a bolt or bolt can be inserted into a corresponding recess in the ground. Such floor locks can secure a sliding door in two dimensions, namely against pushing in or out and against pushing. However, they do not prevent the door from being leveraged. Such locks are usually located in the area of the main closing edge, i. arranged on that side of a sliding door leaf, which defines the door opening in the open state. The opposite side of the sliding door leaf, the so-called secondary closing edge is not secured with such floor locks.

In addition, so-called center locks are known in which a hook or hook-bolt lock two opposing door leaves or a door with a fixed side part are locked together. Such locks also offer no protection against prying. The secondary closing edge is not secured in these locks.

In automatic sliding doors, it is known to block the drive system, e.g. by means of a motor brake or a toothed belt lock. Such blocking of the drive system provides protection only against pushing the door. A pressing in or pulling out and / or levering the door is not prevented.

The pulling or pushing in of the door can be hindered by corresponding guide rails, which as such provide no protection against the sliding of the door leaves. Such guides, as well as separate angles, which are screwed to the floor, can counteract a levering of the door in so far as they extend the Aufhebelweg.

 DISCLOSURE OF THE INVENTION

The known locking systems secure sliding doors only against movements in one or a maximum of two dimensions. If one wishes to secure the movement of a sliding door leaf in all three possible directions, ie against pushing (lateral movement), pulling out or pushing in (movement forwards or backwards) and against levering (movement upwards), then different locking systems have to be combined with each other, which is not only costly, but also usually requires that different locking systems must be operated one after the other individually, which is cumbersome for the user.

The invention is based on the object to provide a locking system by means of which a sliding door can be reliably secured in a simple and cost-effective manner in all three dimensions mentioned. The invention is also based on the object to provide a sliding door system with a corresponding locking system.

The object is achieved by a multi-part locking system with the features of claim 1 and a sliding door system with the features of claim 8. Advantageous embodiments and modifications of the invention are the subject of the dependent claims.

The invention has the advantage of cost-effectively securing a sliding door leaf against slipping, prying and pushing in and out, with the corresponding closure means being provided from a single motion position, e.g. by turning a key, can be operated. The locking system according to the invention is also retrofittable even with existing sliding door systems in a simple and cost-effective manner. In a preferred embodiment, the locking system comprises a special element, with which also the secondary closing edge can be reliably secured against pulling out or pressing.

Further details and advantages of the invention will become apparent from the following purely exemplary and non-limiting description of an embodiment in conjunction with the drawing, which comprises three drawing figures.

 DESCRIPTION OF PREFERRED EMBODIMENTS

In the 1 to 3 is one in its entirety with 10 designated sliding door system shown in a highly schematic, wherein in the 1 and 2 in addition, the floor F of a building on which the sliding door system is mounted, is shown in sectional view. 4 shows details of the sliding door system and in particular the multi-part locking system according to the invention in an enlarged scale.

The sliding door system 10 includes a sliding door wing 12 of which only the lower section is shown here and that can be guided and / or suspended at its upper edge (not shown) in a manner known per se. At this top is also typically a drive for automatically moving the sliding door leaf 12 provided between an open and a closed position. The opening direction is indicated by the arrow R. In the figures is the sliding door wing 12 shown in the closed position, wherein it closes in this position a passage in that the main closing edge 14 of the sliding door leaf 12 against a movable or fixed element, not shown here, for example, a counter-rotating door, a door frame or a fixed element of a sliding door system is applied. If this is a counter-rotating door leaf, it can also be like the door leaf 12 be secured in the manner described below against pulling out, pushing in, pushing on and levering.

On one side of the door leaf 12 is in the region of the lower edge of a lock housing 16 attached, which in this embodiment over virtually the entire width of the door leaf 12 extends. To with a subsequently described retaining element 18 to cooperate advantageous, the housing should be at least the width of the travel of the door leaf 12 have. Alternatively, as described below, on the same side of the door leaf 12 , on the lock housing 16 is arranged to be provided in the region of the lower edge of the door a separate counter element.

The lock case 16 is detachable or insoluble on the door leaf 12 appropriate, but in any case so that it is not readily accessible by unauthorized persons from the door 12 can be solved.

In the lock housing 16 is a hook lock with a locking hook 20 accommodated, wherein the lock in this embodiment with a conventional lock cylinder 22 by means of a key 24 can be pressed to the closing hook 20 from an open position to a closed position, ie from a position in which the closing hook 20 so in the lock housing 16 he retired that he a method of sliding door leaf 12 not hindered, and move to a position in which he is out of the lock housing 16 through a recess in a bottom closure plate 26 protrudes and the bottom closure plate thereby partially surrounds, in particular in 4 clearly visible.

The bottom closure plate 26 is in a conventional manner by means of suitable fasteners 28 anchored at the bottom F of a building or other object in which the sliding door is arranged so that it can not be removed by unauthorized persons in any case in the closed state of the sliding door. As in 2 The bottom closure plate is easy to recognize 26 in the closed state of the sliding door also from the lock housing 16 hidden, so they, as well as the closing hook 20 , is practically inaccessible from the outside.

The bottom closure plate 26 covers a recess 30 Partially in the bottom F and even has a recess not shown here for the locking hook 20 , which is sized and configured so that the locking hook penetrate and then a part of the bottom closure plate 26 can engage around, so that the sliding door is not only against pushing, pulling and pushing, but also against prying, so movements substantially perpendicular to the ground, is secured.

The locking hook 20 and the bottom closure plate 26 are close to the main closing edge in this embodiment 14 arranged. As the bottom closure plate 26 only has to have a small thickness in order to ensure sufficient stability, the bottom plate 26 as in the schematic 1 and 2 indicated, just open the bottom F are placed. Of course, it can also be embedded flush in the ground, so that there is no tripping edge. The recess in the bottom closure plate 26 can be covered with an example spring-loaded flap so that in the open state of the sliding door no dirt through the recess in the bottom plate in the recess 30 can penetrate the ground, the closing hook 20 but can easily push the flap aside when the locking system is about to be completed. The skilled person can advantageously choose the optimum configuration for the particular application and it can also be provided for covering corresponding recesses in the bottom closure plates, especially for larger sliding door systems and automatically operated locking systems, which are moved automatically.

In the area of the so-called secondary closing edge 32 , so the main closing edge 14 opposite side of the sliding door leaf 12 , is the already mentioned holding element 18 arranged that in this embodiment in a known manner at the bottom F is anchored, but that may be attached to other parts of the door system itself in other sliding door systems also on fixed parts. The holding element 18 surrounds the lock housing in this embodiment 16 partially and prevents the sliding door 12 when closed in the area of the secondary closing edge 32 levered or in the direction of the holding element 20 can be pressed. In order to enable this advantageous interaction of lock housing and retaining element, the lock housing extends in the embodiment shown over virtually the entire width of the door leaf 12 , Alternatively, on the same side of the door leaf 12 , on the lock housing 16 is arranged, in the region of the lower edge of the door leaf 12 a separate counter element is provided that, like the lock housing is mounted so that it can not be easily removed by unauthorized persons, and which is intended to, with the holding element 18 to work together to prevent it from being leveraged. The solution with a continuous housing is currently preferred because it not only offers aesthetic advantages, but also prevents with a single continuous surface, for example, the foot of a person staying in the door area when moving the door from a projection on the door, such as it would result if the housing did not extend over substantially the entire width of the door leaf.

The door is pulled out in the area of the secondary closing edge 16 usually not possible because the minor closing edge 32 is typically obscured by a fixed element of the sliding door system.

Depending on the design and location of the sliding door system can be provided that the locking system can be operated from both main sides of a sliding door, what then the sliding door must have a corresponding recess to access from the lock housing remote from the side of the sliding door from an access to a to allow at least one lock-operated locking cylinder, if of course provided a manual actuation of the closing hook. Namely, the invention makes it possible to actuate the locking hook in a manner optimally adapted to the particular application, i. ie e.g. manually by means of a key and a lock cylinder or automatically by means of electrical, hydraulic or pneumatic drives. In particular, when an automatic actuation of the closing hook is provided, the sliding door system or the locking system according to the invention may advantageously be equipped with means which generate and output a signal representative of the closing position of the closing hook. This signal can e.g. be used to control a visual indication of the closed state or to report the closing state to a higher level control unit that has sent a close command to the locking system.

Within the scope of the inventive concept, numerous modifications and developments are possible, e.g. refer to the number and design of the locking hook and the bottom closure plate. Thus, it can be provided that instead of a single closing hook a plurality of hooks arranged in series are actuated jointly or separately and can engage in corresponding recesses of one or more bottom closing plate (s). Here, the invention advantageously allows the person skilled in the art to choose the optimum configuration for the particular application. From the above description it is also clear to the person skilled in the art that the invention can be used advantageously not only for new sliding door systems but also for retrofitting existing sliding door systems in a simple and cost-effective manner, wherein the hook lock according to the invention together with the closing plate movement of the sliding door in ensures three dimensions. A particularly advantageous embodiment results with the optionally provided holding element which can cooperate with the lock housing in order to secure the secondary closing edge of the sliding door. In this case, the lock housing then not only has a passive function to cover the hook lock, but also an active function to secure the sliding door.
