Description

The invention relates to a locking system for doors, windows or the like, in particular a espagnolette lock with panic function and multipoint locking.

Door locks with panic function are in different embodiments known, and also for doors with multi-point locking. The well-known Door locks with multi-point locking and panic function become to Locking with a door key operated via a lock cylinder. The Panic opening, d. H. the retraction of all locking points without door key takes place from the inside of the door, by pressing a Door handle or a bar fitting. To open the panic lock to avoid from the outside of the door, there is a regular Used fitting that does not allow the lock nut to rotate and to unlock the door lock. For multi-point locks with bilateral Door handles can always only the Lock latch be retracted, d. H. in the closed state is the door from the outside without door key not open.

In the known embodiments, the lock side with the panic function fixed unchanged by the door assembly. Consequently, doors have to with door locks for DIN left or DIN right separately manufactured and on Order to be delivered. This initially arises once the Locksmith costs by setting up two different lock types. The processors have the disadvantage of stocking them up Both lock versions additional costs for double storage arise. - Regardless, multipoint interlocks are required for Locking must be operated via the door key / lock cylinder, often unpopular. Preference is often given only handle-operated Multipoint locks. In these, the extension of the Locking points by pulling up the door handle. To save the pre-locked state, the center bar is one-way locked in locked position. In such embodiments, the panic function is generally absent. The key operated versions with multipoint interlock and Panic function are relatively due to particular their transmission gear costly, at least much more expensive in their production and Acquisition as the comparatively simply constructed, press-operated Versions.

The invention is based on the object, a locking system for doors, Window or the like, in particular a drive rod lock with panic function and multipoint interlocking, which acted as a push-button Version by a relatively simple, functional and cheap Structure distinguishes and beyond for both doors DIN links as well also DIN-law can be used.

To solve this problem is the subject of the invention

• the chain driver interacts with the lock chain and the panic driver with a panic transmission lever,
• a longer handle bolt can be inserted into the first half of the lock nut (or second half of the lock nut) and, on actuation, takes along the panic catch and the chain catch with a predetermined clearance,
• a shorter pusher bolt can be inserted into the second half of the lock nut (or first half of the lock nut), which actuates the associated chain catch with a predetermined clearance,
• a pivotally mounted inner latch is adjustable by means of the lock cylinder in a lock chain blocking the dead center position when the central bolt is extended and in the locking position
• the Panikübersetzungshebel cooperates with the inner latch in (door inner side) handle operation of the longer pusher bolt in the lock-opening sense.

The locking system according to the invention with multi-point locking and panic function is a press-operated embodiment. The multipoint interlock consists of the central castle and others on a common cuff attached additional locks that are operated via the drive rods. These rods are located behind the cuff and are by the moved multipart lock nut, and thereby drive the additional locks at.

The central lock has next to the lock latch a central latch and the as it were four-part castle nut. The Schlossnusshälften be over the Handle bolt coupled to the door handle. The central castle can be over the lock cylinder - regularly in the embodiment of a profile cylinder - block against unauthorized opening from the outside. From the inside of the door All locking points can be accessed at any time without a door key simply pressing the door handle and thus pressing the longer one Be retracted pusher bolt. Due to the special structure of the four-part Lock nut with the two halves of the lock nut, the panic catcher and the chain link, and taking into account the two associated different-length pusher bolts, a pusher actuated panic multipoint locking created for both doors DIN links as well DIN-law can be used. On which side of the castle are the Panic function is to be located by the fitter by the optional plugging set the handle bolt. The longer handle bolt operates basically the panic catcher and defines the inside of the door. Except for yourself Known implementation of the latch need no further changes to be made on the locking system.

Other inventive measures are listed below. So The first half of the lock nut and / or the second half of the half lock nut can be two on a turning circle offset by a predetermined angle of rotation driving arms have, between which in each case a driving cam of Kettenmitnehmers protruding, wherein between the first half of the lock nut and the Kettenmitnehmer a clearance of 40 ° to 50 °, preferably 45 ° is formed. There is a possibility that the chain driver after his Operation in its assumed position stops while the Turn the locknut halves back to their original position with the spring force applied. Appropriately, the Panikmitnehmer one of the associated Driving cam of the chain drive with predetermined Motion play penetrated opening on, so that the chain catcher can also be taken from the Schlossnusshälfte, the is on the side of the panic taker. In addition, the Panikmitnehmer partially in a bed-like depression of Kettenmitnehmers be stored. The chain driver preferably has a fork-shaped Recording for an actuating cam on the lock chain or on a assigned chain lever on the lock chain, so that the operation of the Kettenmitnehmers on one or the other handle bolt on the Lock chain is transmitted and thereby actuation of the central bolt and the drive rods and consequently the additional locks in the closed position or open position. The reversal is conceivable, after which So the Kettenmitnehmer an actuating cam and the lock chain a having fork-shaped receptacle for the actuating cam. - Next sees the Invention that the Panikmitnehmer a on a cam on the pivotally mounted panic gear lever operating control pin having. Also in this case the reversal is possible. In both cases will the panic transmission lever clockwise or counterclockwise pivoted. According to the invention, the panic driver has a bolt receptacle for a longer multi-edge end, z. B. square end, the longer Pusher bolt, wherein the bolt receptacle 40 ° to 50 °, preferably 45 ° free-ratchet for the longer handle bolt. Due to the longer polygonal end engages the longer handle bolt basically in the Stud recording the panic driver, so it does not matter if the longer Handle bolts from one side of the door or from the other door side in the lock nut is inserted, so that the door side is the inside of the door, on which the longer handle pin is located and the triggering of the panic function allows. This also results in the possibility of use the locking system according to the invention or a so equipped Door as a door DIN left or door DIN right. Consequently, the longer one Handle bolt with its longer polygonal end also in the second half of the castle nut and the shorter pusher bolt with a shorter polygonal end, z. B. square end, insertable into the first half of the lock nut, wherein the longer polygonal end of the longer pusher bolt takeaway or with predetermined movement through an opening in the Kettenmitnehmers through in the free-locking mechanism of the panic penetrates his activity. The 45 ° free-ratchet mechanism ensures that the Panic catch after actuation by the longer handle bolt in his occupied position stops, while the Schlossnusshälften Turn back spring loaded to the initial position. Through a Rotating the panic detent can lock the locked position Locking system can be canceled without a door key, regardless of which door side is the longer handle bolt. The handle bolts preferably have a multi-edge limiting collar, z. B. a lock washer or the like and are of a on the Surrounding collar seated compression spring, which against the inside of the Door shield presses, in the installed state, the wandering of the Handle bolts from the lock nut or their associated locknut halves to prevent. The collar also limits as it were Stop element the penetration depth of the handle bolts into the locknut halves. The shorter handle bolt is always inserted from the outside of the door. about he can only use the lock nut when not locked or when not locked locking system are actuated. The insertion side of the longer Handle bolt defines the panic side of the locking system, as in a Handle operation via this longer handle bolt the locking system also in the locked state and consequently with locked locking system, the over Lock cylinder has been completed, can be opened at any time.

Next, the invention provides that the two Schlossnusshälften back (On the side facing away from the lock nut chain) Formations or approaches have, the fall side of at least one common spring-loaded Return plunger and on the opposite side separated from each act on its own spring-loaded return ram, to allow a separate provision of the two Schlossnusshälften. The panic transmission lever is pivotally mounted and works on one Locking cams on the inner latch below the pivot axis of this inner latch. Conveniently, a spring-loaded on or in the inner latch Guard on the lock cylinder side facing out, the one having a control cam cooperating control pin and of a driving lug of the lock cylinder is actuated. It can the Guard locking one of the driving lug of the lock cylinder associated V-shaped Have running surface or sliding surface and is opposite the inner bar in front. - The blocking of the previously pre-locked by a lever handle position via a key turn of the lock cylinder. This will be the Internal latch in a dead center position generating position to the lock chain turned in. The guided in the inner bar and by spring force applied tumbler positions itself in its two end positions the control cam inserted in the lock case. The cam is like that designed so that the inner bolt does not accidentally out of its two Shift out end positions. Only by the pivoting of the Panic driver can via the Panikübersetzungshebel the inner latch and the tumbler are moved from the locked position to the open position. To ensure that the cam lug of the lock cylinder is always far enough is pushed out of the transport area of the inner bar is the lower sliding surface of the tumbler designed V-shaped and facing the tumbler formed protruding the inner bar.
