Description

The invention relates to a locking system in the embodiment as espagnolette lock for sliding doors, sliding windows or the like sliding elements, with at least one attachable to the door lock, which is designed as a central lock and a lock housing and a lock cylinder and optionally a lock nut for handle operation and having a on the Door frontally attachable lock cuff, arranged with one or more above and / or below the central lock and optionally on the lock face back fastened (Zustatz-) locks, with one or more behind the lock plate slidably guided and the locks actuated drive rods, the lock cylinder on in the lock housing slidably guided espagnolette works on the drive rods, and wherein the espagnolette with the interposition of espagnolette adapters (17) to the drive rods ang are closed. These are z. As an espagnolette lock with multi-point locking and possibly panic function and / or electronic motor drive. In this respect, the locking or unlocking can be done via an electric motor drive, which is operated either with a door key with the lock cylinder or by a remote control. In any case, a lock cylinder is necessary, the electromotive variants at least as an emergency opening or closing function in case of power failure serves. Incidentally, a pusher can be provided for Panikentriegelung working on a lock nut.

From practice, such espagnolette locks are known with multi-point locks for installation in double doors or windows. The central lock, the (additional) electromotive drive unit and the additional locks are housed with their additional locking boxes within the door or in the door profile. All components are mounted on the back on a continuous lock cuff. The entire system is bolted to the door profile from the lock face front. The lock cylinder is then pushed through the intended lock cylinder opening through door profile and lock until the center of the lock cylinder coincides with the cylinder screw hole of the central lock. Only then is screwed together with a fixing screw lock cylinder stulpseitig.

Furthermore, one knows sliding doors, which are used for example in entrance areas of public buildings and in embodiments as glass doors from one or more door profiles (made of metal) and a recorded from the door profile glass. The use of the known espagnolette locks is only limited possible with sliding doors or windows. For in particular with door profiles with a small thickness, there is the problem that the lock cylinder (on both sides) protrudes from the door profile. If it involves sliding doors or windows in which the element to be moved due to the design has to be passed very close to the fixed element, there is the problem that the projecting lock cylinder abuts against the fixed element. This leads on the one hand to the fact that the sliding door only up to this On the other hand, there is a risk that it will damage the lock cylinder or the entire espagnolette lock. This problem occurs in particular when conventional lock cylinder a minimum length of 60 mm at z. B. aluminum door profiles with thicknesses between 30 mm and 50 mm to be used. The use of known short cylinder should also be avoided here, since they can be operated either only from the inside or from the outside. Finally, it is also not possible to push back the lock cylinder in the door profile until its head face flush with the door profile flush or even something rests, because then the center of the lock cylinder would lie with the cam outside the central lock. This is where the invention starts.

Incidentally, one knows from the EP 0 566 447 A an externally mounted on a door or window profile lock, which operates on actuation pins on a drive rod. In the lock passages are integrated for attachment to the door.

The FR 2 432 076 A1 describes a lock, which is externally placed on a door or window sash, but is not designed as a drive rod lock.

Finally, out of the GB 2,164,382 a window closure known, the actuating handle is placed as usual on the outside on a window profile.

The invention has for its object to provide a locking system, namely a drive rod lock, which can be used in a simple and inexpensive construction and full functionality in the field of sliding doors, in particular using conventional locks or lock cylinder.

To solve this problem, the invention teaches in a generic locking system of the type described above, that one or more mounting brackets are releasably secured to the lock housing of the central lock, the lock housing with these mounting brackets outside of the door or can be fastened to this. Outside the door means within the scope of the invention that the lock housing is not fully integrated as usual in the door or a door profile and thus disposed within the door profile, but placed on one of the door outer surfaces or door profile outer surfaces or attached. Outside door surfaces here means both the front and rear or the door surface associated with an exterior space and an interior space. The attachment of the lock housing on one of these outer door surfaces is carried out by separate mounting bracket, which are connected on the one hand with the lock housing and on the other hand with the door. In this respect, it is within the scope of the invention, the possibility of using conventional lock housing, which are then fastened using specially made mounting bracket on the outside of the door and therefore as it were next to the door. It is of course expedient To secure the lock housing with the mounting brackets on a sliding door on the exterior door surface facing away from the fixed element of the sliding door, so that the sliding door can then be fully opened without collisions. However, the invention is not limited to locking systems for sliding doors, but can also be realized in folding doors (or swivel or hinged doors).

Of particular importance is the inventive idea in connection with a drive rod lock of the type described above. In such a drive rod lock, the invention proposes that the drive rod slides are connected with the interposition of drive rod connection adapters to the drive rods. The invention is based on the recognition that it is possible with a espagnolette in connection with a sliding door or the like, not to arrange the central lock itself as usual on the back of the continuous cuff in the door profile, but outside of the door profile and at the same time also provided the drive rods and to accommodate the (additional) locks in a conventional manner in the door profile. This results in an "offset" between the central lock on the one hand and the drive rods or the additional locks on the other hand, that is, the central lock on the one hand and the drive rods and additional latches on the other are arranged in different levels. This offset is compensated according to the invention via the drive rod connection adapter, which ensure the proper power transmission from the central lock on the drive rods and consequently additional latches. For this purpose, the drive rod connection adapter are preferably designed as fork arms with the drive rods associated end-side fork receptacles, in which arranged on the drive rods connecting elements, for. B. Connecting bolt, engage. The fork arms can engage in slots in the door or pass through these slots. In this respect, with the simplest installation a perfect coupling of the lock on the drive rods, because in the course of placing the lock housing on one of the door outer surfaces, the fork arms pass through the slots in the door profile and thereby include the connection bolts connected to the drive rods, so that in the course of the operation Displacement of the espagnolette immediately the fork arms are moved and thus the connection pins and the associated drive rods are taken. In particular, when used in conjunction with sliding doors, there is the possibility that the lock in the espagnolette lock according to the invention only via the separate (additional) locks, ie the central lock itself then has no own locking elements or the like, such. As a bolt or a trap on. This is useful because the central lock is arranged with "offset" to the lock cuff. In this respect, it is also not necessary to provide a "staggered" locking receptacle for the central lock on the fixed counter element. When using the lock according to the invention in connection with folding doors (or swing doors), however, it may be expedient to provide in the central lock locking and / or closing elements, for. B. a bolt and / or a trap.

The mounting bracket are formed according to a preferred embodiment as L-shaped, C-shaped or T-shaped mounting profiles, which at least one door attachment leg and at least one z. B. orthogonal thereto arranged Schlossbefestigungsschenkel. About the door attachment leg doing the attachment of the mounting bracket to the door or on the door profile and the lock mounting leg attachment of the mounting bracket to the lock or on the lock housing. For this purpose, the door attachment leg preferably one or more, z. B. two fastening holes for screws or the like fasteners, these mounting holes are aligned in the course of installation with corresponding threaded holes or the like in the door.

A particularly simple attachment of the mounting bracket to the lock housing is possible when the lock attachment leg has a mounting lug or insertion nose, which engages in a corresponding receiving or insertion pocket of the lock housing or can be inserted. Such an embodiment is particularly useful when conventional locks are to be used, which have a corresponding receiving pocket for other purposes. In this respect, it makes sense to adapt the mounting bracket to the construction of known lock housing to ensure the universal use of such locks. In this case, each lock housing preferably has such a receiving pocket, in each case at the upper housing end and at the lower housing end, so that the mounting brackets then connect to the lock housing on the upper side and the lower side in the mounted state. In particular, in embodiments with the described insertion nose or insertion pocket, it is expedient if a cover strip is fastened to the lock housing on the end face associated with the lock faceplate. The cover strip is preferably attached to both the lock housing and the mounting brackets, z. B. by means of screws. Thus, first, the mounting bracket can be attached to the lock housing, z. B. by means of screws. Then then the cover strip to the lock housing and / or to the mounting bracket be screwed. In this context, it is expedient if the lock fastening leg of the mounting bracket has at least one fastening receptacle into which a fastening means, for. B. engages a screw of the cover in the course of attachment. It is particularly advantageous if, alternatively or additionally, the lock fastening leg has at least one (end-side) adjustment pin, which engages in an adjustment receptacle (eg opening) of the cover strip. It is further provided that the lock attachment leg and preferably the insertion nose has a receptacle for a screw of the lock housing. The insertion nose preferably extends substantially parallel to the door attachment leg.

According to a further proposal of the invention, which is of particular importance, it is provided that the mounting bracket has one or more (lateral) mounting pins which engage in the course of installation of the lock on the door in the mounting pin associated mounting receptacles of the door. Taking into account these mounting pins and the corresponding mounting shots successful automatic and accurate positioning of the lock on the door, so that it is always ensured that the lock is arranged in exactly the desired position on or on the door profile, so that then the corresponding fasteners and in particular, the locking receptacle are positioned exactly correct. In terms of manufacturing technology, the desired positions of the mounting receivers, taking into account the intended positions of the fastening receptacles and the lock cylinder receptacle can be automatically introduced to the door profile, for. B. in the way of a CNC production. It is particularly advantageous if each mounting bracket on both sides at least each has a mounting pin. This configuration allows the universal use of the mounting bracket on different sides of the door, since in each case a corresponding mounting pin is available.

In terms of manufacturing technology, it is particularly advantageous if the mounting bracket with optionally the mounting pin and / or the alignment pin are made in one piece, for. B. as one-piece cast components. In this case, the mounting bracket may preferably be formed of metal, for. B. as die-cast components, eg. B. zinc die-cast components.

Furthermore, it is z. B. for aesthetic reasons advantageous to provide a cover covering the lock housing, which is placed on the lock and on the door and / or on the lock housing and / or on the mounting bracket can be fastened. It is particularly advantageous if the cover housing is fastened to the mounting brackets.

Overall, the locking system according to the invention allows the use of conventional central locks and in particular conventional lock cylinder even with sliding doors with narrow door profiles of a width between 30 and 50 mm. The lock cylinders can then be used even if they have a minimum length of 60 mm (30 mm / 30 mm). The use of only one-sided actuated short cylinders is not required but basically possible. Nevertheless, the sliding elements (eg sliding doors) can be guided very close to the corresponding stationary element without the risk of a collision of the locking cylinder with the stationary element. This succeeds in universal use of the locks used, since the attachment of the central lock using mounting brackets. The mounting bracket fulfill a multiple function, because they are on the one hand attached to the central lock and on the other hand on the door profile. In addition, they allow the attachment of the cover housing described and they are preferably provided with corresponding Justage- or mounting devices, which make a complex alignment of the castle relative to the door profile unnecessary. In addition, they are universally applicable for DIN left and right.
