Abstract

The lock has a central bar (6) and an auxiliary bar (11), which are transferred from a locking position in to an unlocking position by a central lock (1). The central bar and the auxiliary bar are automatically transferred from an unlocking position in to a locking position with a door wing in a closed position. A lock nut (8) is formed as a splitted lock nut with a nut halve that is assigned to a door outer side, and another nut halve assigned to door inner side. One of the nut halves is blocked by a blocking lever operated with a locking cylinder.

Description

Description:

The invention relates to an espagnolette with panic function and multiple locking, with at least one central lock with at least latch, central latch, lock nut and lock cylinder and at least one additional latch with at least one additional latch, wherein the central lock is connected via at least one drive rod with the additional latch, wherein central latch and additional latch can be transferred via the central lock from a locking position into an unlocking, the lock nut for the purpose of Panikentriegelung on the central bolt and the auxiliary bolt actuated rods works and wherein the central bolt and the additional bolt are automatically transferred in the closed position reaching door from the unlocked position into the locked position ,

The central lock can be actuated in particular via a pusher and / or fitting, which works on the lock nut. Additional bolt of additional locking means z. As a bolt, a latch bolt, a latch, a locking bolt or a pivot hook. Such a locking element of the additional locking is to be transferred automatically in the closed position reaching door leaf in the locked position and thus be automatically excluded, so that at zufallendem door an automatic locking (the additional locking) takes place. The triggering can be z. Example, by a trigger magnet, which may be mounted in the region of a door frame-side locking bar and works for automatic locking on a arranged in the additional locking lock element, so that this locking element unlocks the lock chain of the additional lock, and thereby automatically transfers the additional lock in the locked position. The central lock has a movable central lock chain and the additional lock on at least one connected to the central lock via the drive rod auxiliary lock chain. In the course of the automatic locking of the additional locking the auxiliary lock chain is moved. In this case, the auxiliary lock chain can work on the drive rod on the central lock chain in the course of self-locking and thereby transfer in the course of self-locking the additional locking the central bolt of the central lock from the unlocked position into the locking position.

Such a self-locking espagnolette with multiple locking is from the DE 20 2009 007 674 U1 known. In this lock takes place in the course of closing the door, an automatic locking not only the additional locks, but also the central lock. In practice, it has also been proposed to equip this known self-locking espagnolette lock with multiple locking also with a panic function. Consequently, by pressing or fitting operation from inside all the locking elements of the central lock and the additional locks can be transferred from the locked position into the unlocked position. It is worked with a continuous nut. From the inside, the door can be opened by pressing the handle or a bar handle, from the outside via the lock cylinder.

The extent known castle has been proven, but it is capable of further development in functional terms. Thus, there is a need to provide a kind of self-locking espagnolette lock, which is provided on both sides with door handles or Betätigungsbeschlägen, so that a perfect passage function is ensured. It may be z. B. exterior doors of public buildings, z. B. act schools that are open at a daytime operation from the outside easily via a pusher should. Of course, in a night operation, ie locked or secured lock from the outside no access is possible. Nevertheless, a panic unlocking must always be possible from the inside. However, it should be prevented after a Panikentriegelung that the door lock then remains in an unsecured state. - This is where the invention starts.

The invention has for its object to provide a drive rod lock with panic function and multiple locking, which is characterized by a simple structure by increased functionality and security in particular.

To solve this problem, the invention teaches in a generic espagnolette lock of the type described above, that the lock nut is formed as a split locknut with at least one of the outside door associated first half nut and the inside of the door associated second half nut, wherein the first half of the nut operable by means of a lock cylinder Blocking lever is blocked.

The invention is based on the recognition that the functionality of a self-locking espagnolette lock with panic function and with multiple locking, as for example from the DE 20 2009 007 674 U1 is known, can expand, in which a real "passage function" is realized without having to do without a self-locking or panic function. The use of a split locknut initially makes it possible, not only in the area of the inside of the door, but also in the area of the outside of the door, to provide a pusher or a comparable fitting for easy opening of the door by pulling back the latch. Also a change function or a change lever, with the one Retraction of the lock latch via the lock cylinder is not mandatory. Instead, the lock can also be opened from the outside of the door via the door handle or a comparable fitting. Nevertheless, an exchange function can be provided in practice. The from the DE 20 2009 007 674 U1 known self-locking all the castle components, namely on the one hand the central lock and on the other hand, the additional locking remains intact. As soon as the door closes, all locking elements are moved into the locking position. Since the lock nut or both nut halves of the lock nut work directly or indirectly on the central lock chain, all unlocking elements and, incidentally, the lock latch of the central lock can be readily withdrawn from both sides, so that a real through function is realized.

The locking of the already self-locking of the door self-locking locking system from the outside via the lock cylinder. In the context of the invention, the lock cylinder operates on a locking lever arranged in the central lock, which blocks the first lock half, which is assigned to the outside of the door. Thus, a backup of the previously "self-locked" locking system is ensured in a simple manner, without an expensive freewheel or clearance or a costly decoupling of closing and / or locking elements is required. The two lock nut halves can still work indirectly or preferably directly on the lock chain. However, as soon as the lock has been secured via the lock cylinder, an opening is only possible from the inside of the door, since the lock nut half assigned to the outside of the door is blocked by the lock lever. The blocking lever is consequently only in operative connection with one of the lock nut halves, namely with the first half of the lock nut, which is assigned to the outside of the door.

The espagnolette lock according to the invention can be used for example for exterior building doors or other passage doors in buildings, z. As public buildings, office buildings or the like, which must be randomly locked or secured at certain times of the day and to ensure a free passage at other times and in which additionally always a panic opening from the inside should be possible. So z. B. transferred in the daytime operation of the blocking lever on the lock cylinder from the blocking position in a release position. Then takes place when the door leaf is closed always a self-locking, d h. all locking elements are extended to their locking position. Nevertheless, the door can be opened both from the outside of the door and from the inside of the door via the handle or a corresponding fitting, since both lock nut halves are then freely operable and each work on the central lock chain and thus on the espagnolettes on the auxiliary lock chain. The self-locking is therefore always canceled by pusher or fitting operation. If the espagnolette z. B. are secured in a night operation, it is only necessary to transfer the lock cylinder from the release position to the locked blocking position with the lock cylinder. This succeeds mechanically in a very simple way. In this secured functional position (eg in night mode), the first half of the lock nut is then blocked so that it is no longer possible to access it from the outside. Nevertheless, the unlocking and opening function of the inside of the door remains unaffected, ie the door can always be opened from the inside, so that a reliable panic function is realized. Of particular importance is the fact that z. B. in night mode after panic unlocking from inside the espagnolette lock after the door leaf has fallen back into a secure functional position in which access from the outside is reliably prevented. For one thing, after the door leaf has fallen, all the locking elements in the locking position become automatic again transferred. On the other hand, the blocking function of the blocking lever with respect to the first half of the lock nut remains unaffected by the panic unlocking via the second half of the lock nut, so that the building is subsequently properly secured again even after a panic opening from the inside.

Although the use of a split locknut is generally known in connection with espagnolette locks of other functionality (cf. DE 10 2004 012 108 A1 ), but usually a clearance or Lehrhub is realized in the area of the outside of the door to prevent access from the outside. The blocking function using the blocking lever is therefore of particular importance in the context of the invention.

Incidentally, the espagnolette lock according to the invention is also advantageous from a fire protection point of view. Since the blocking of a complete actuation of the locking system and thus retraction of the case is avoided in the locked state, the door always remains in the locked and secured functional position completely "at the ready", so that a high sealing function is guaranteed. There is no danger of the door wing pulling away from the seal by retracting the latch until the locking elements prevent further opening of the door.

• So schlägt die Erfindung vor, dass der Blockierhebel verschiebbar in dem Zentralschloss bzw. Zentralschlossgehäuse gelagert ist und im Zuge der Blockierung und Freigabe der Schlossnuss vorzugsweise in Treibstangenlängsrichtung, d. h. parallel zu der Treibstangenbewegungsrichtung und/oder Schlosskettenbewegungsrichtung verschiebbar ist. Die Blockierung lässt sich auf diese Weise mechanisch sehr einfach realisieren, da es lediglich erforderlich ist, den Blockierhebel durch Betätigung des Schließzylinders innerhalb des Schlossgehäuses zu verschieben. Dazu weist der Blockierhebel zumindest eine erste Betätigungsfläche auf, gegen welche der Schließzylinder bzw. dessen Schließnase oder ein mit der Schließnase gekoppeltes Schließelement im Zuge der Blockierung arbeitet und eine zweite Betätigungsfläche, gegen die der Schließzylinder oder z. B. die Schließnase des Schließzylinders oder ein mit der Schließnase gekoppeltes Schließelement im Zuge der Freigabe arbeitet. Dabei ist es grundsätzlich möglich, dass die Schließnase des Schließzylinders unmittelbar auf diese Betätigungsflächen arbeitet. Die Erfindung umfasst jedoch auch Ausführungsformen, bei denen die Schließnase über ein Schließzylinderelement, z. B. ein Zwischenelement oder dergleichen auf die Betätigungsfläche arbeitet.

Advantageous developments of the invention are explained below:

• Thus, the invention proposes that the blocking lever is slidably mounted in the central lock or central lock housing and in the course of blocking and release of the lock nut preferably in the drive rod longitudinal direction, ie parallel to the drive rod movement direction and / or lock chain movement direction is displaceable. The blocking can be in this way mechanically very easy to implement, since it is only necessary to move the blocking lever by pressing the lock cylinder within the lock housing. For this purpose, the blocking lever has at least one first actuating surface, against which the lock cylinder or its closing nose or a locking element coupled to the closing element operates in the course of blocking and a second actuating surface, against which the lock cylinder or z. B. the locking lug of the lock cylinder or a locking element coupled with the closing element in the course of release works. It is basically possible that the locking lug of the lock cylinder works directly on these actuation surfaces. However, the invention also includes embodiments in which the locking lug on a lock cylinder element, for. B. an intermediate element or the like works on the actuating surface.

In order to further increase the safety of the lock, it may be appropriate to provide a locking lever in addition to the blocking lever, so that the blocking lever can be locked by means of the locking lever in the blocking position. The locking lever can be pivotally mounted in the lock housing. Preferably, the locking lever by means of spring force and / or gravity in the blocking position locking locking position can be pressed. The locking lever can z. B. be acted upon by a locking spring. If such a locking lever is provided, it is advantageous if the lock cylinder works in the course of the transfer of the blocking lever from the blocking position to the release position not only on the blocking lever, but also on the locking lever by the locking lever is then pivoted, for example, to release the locking lever ,

In order to realize the blocking of the first half of the lock nut by the blocking lever, it is expedient if the first half of the lock nut has a Has blocking stop, which cooperates with the blocking lever. In the blocking position of the blocking lever, the blocking stop comes into contact with the blocking lever, so that rotation of the lock nut half is prevented. It may be sufficient to design only the first half of the lock nut with a blocking stop. For manufacturing reasons and assembly reasons, however, it may be expedient to provide both lock nut halves with a blocking stop, wherein the blocking lever then only projects into the area of the blocking stop of the first half of the lock nut. This has the advantage that only by replacing the blocking lever with otherwise identical Schlossnussausgestaltung the central lock for different installation situations can be used, depending on the outside of the door and the inside of the door.

Furthermore, it is expedient if the blocking lever has at least one first locking nose, which cooperates with a corresponding blocking surface of the locking lever.

According to a further proposal, it is provided that the two lock nut halves work indirectly or preferably directly on the central lock chain. By pusher or fitting operation and consequently by pivoting the respective lock half, the central lock chain is moved from the locking position to the unlocked position. This will bring back the central bolt. In addition, the drive rods are moved and thus moved the additional lock chains, so that the additional latch from the locked position are transferred to the unlocked position. It is also useful if the lock nut works in a conventional manner on the latch, so that the lock nut is retracted in the course of actuation of the respective half-castle nut. These functions can be used for both locknut halves Be carried out identically, since the real "locking" or securing the locking system is realized only on the lock cylinder and the displacement of the locking lever, so that then the outside of the door associated final nut is blocked.

The figures show an attachable to a door espagnolette, which as a locking units on the one hand a central lock 1 and on the other hand, upper and lower additional latches 2, which are secured to the rear of a (common) lock plate 3 (see. Fig. 1 ). The central lock 1 and the additional locks 2 are connected to each other via drive rods 4. The central lock 1 has a latch 5, a central latch 6, a central lock chain 7, a lock nut 8 and a corresponding receptacle 9 for a lock cylinder, not shown. The central lock chain 7 is arranged in drive rod longitudinal direction L in the lock housing 10 of the central lock and slidable in drive rod longitudinal direction L. The additional latches 2 each have an additional latch 11, which is formed in the embodiment as a latch bolt. Furthermore, the additional latches 2 each have a sliding in the auxiliary lock housing 12 in the drive rod longitudinal direction L additional lock chain.

In the course of unlocking on the central lock 1, the central lock chain 7 and the associated drive rod 4 works on the attached additional lock chain 13 of the additional lock 2. By means of the central lock chain of the central bar 6 is transferred from an excluded locking position into an enclosed unlocking position and vice versa. By means of the additional lock chain 13, the latch bolt 11 of the additional lock 2 is transferred from an excluded locking position into an enclosed unlocking position and vice versa. The unlocking of the additional locking takes place by actuation of the central lock 1 and consequently via the drive rods 4, which transfers the auxiliary lock chain 13 from the locking position into the unlocked position. The locking of the additional locking takes place automatically or automatically as soon as the door or the door leaf reaches the closed position. For this purpose, it is provided that the additional lock chain 13 of a locking element 14 initially in the unlocked position is held and that in or on one of the Zuatzverriegelungen 2 associated door frame-side locking strip 15, a release magnet 16 is arranged. This closing strip-side release magnet 16 operates for automatic locking or for an automatic release on the locking element 14, which then releases the auxiliary lock chain 13, so that the auxiliary bolt 11 is transferred to the locking position. At the same time, however, the auxiliary lock chain 13 operates on the drive rod 4 on the central lock chain 7 in such a way that in the course of self-locking the additional lock 2 also the central latch 6 of the central lock 1 is transferred from the unlocked position into the locking position. In the context of the invention, therefore, a complete self-locking is provided, which relates to both the additional locks 2 and the central lock 1. For this purpose, the central lock chain 7 operates via a pivotally mounted in the central lock housing 11 locking lever 17 on the central latch 6. This results in particular from a comparative analysis of Fig.2 and Fig. 3 or from a comparative analysis of Fig. 4 and Fig. 5 , Fig. 2 and Fig. 4 show the espagnolette lock in the unlocked position while Fig. 3 and Fig. 5 show the espagnolette lock in the locked position. The Fig. 4 and Fig. 5 show the central lock 1 from a different view than the Fig. 2 and Fig. 3 ,

A comparative analysis of the Fig. 2 and Fig. 3 first clarifies the self-locking mechanism for the additional lock 2, and he also, for example, in the DE 20 2009 007 674 U1 is described. In the functional position according to Fig. 2 the trigger magnet 16 is far away from the espagnolette lock, so that it does not affect the blocking element, which is formed in the embodiment as a linearly displaceable locking pin 14. In the in Fig. 2 illustrated basic position engages the locking pin 14 with its lock-side end a locking projection or a locking edge 18 of the auxiliary lock chain. The auxiliary lock chain 13 is on the one hand by the blocking force and on the other hand (indirectly) via a locking spring 19 from the unlocked position in the locked position transferred as soon as the trigger magnet shifts the locking pin 14 and this releases the auxiliary lock chain 13. The coupling between the additional lock chain 13 and the auxiliary bolt 11 via an intermediate lever 20, which is designed as pivotable about the axis 21 hinged to the lock housing pivot lever. In the exemplary embodiment, this intermediate lever is designed as an L-shaped lever 20. This has a first arm 20a, which is associated with the auxiliary lock chain 13 and a second arm 20b, which is associated with the auxiliary bolt 11. In addition, this intermediate lever 20 (indirectly) is acted upon by the locking spring 19. Although the locking spring 19 is anxious to push the latch bolt 11 in the locking position, such a lock in the functional position according to Fig. 2 blocked because the auxiliary lock chain 13 is blocked by the locking pin 14, so that the connected to the auxiliary lock chain 13 intermediate lever 20 holds the latch bolt 11. Approaches now in the course of closing the door, the additional locking 2 of the locking bar 15, the magnet 16 triggers the automatic locking, so that the locking pin 14 now releases the lock chain of the auxiliary lock 2, so that the additional bolt 13 via the gravity of the lock chain and on the other hand is transferred via the spring force of the locking spring 20 in the locking position, in which the auxiliary bolt 13 is excluded (see. Fig. 3 respectively. Fig. 5 ). The closing strip 15 is only in Fig. 2 indicated.

The automatic locking is not limited to the additional lock 2, but it also affects the central lock 1, as can be seen from a comparative analysis of Fig. 4 and 5 results. Also this functionality is already in the DE 20 2009 007 674 U1 described. In the course of self-locking not only the auxiliary lock chain 13 along the drive rod longitudinal direction L is moved, but with this also the drive rod 4 coupled thereto, which in turn is connected to the central lock chain 7. Thus, a connected to the central lock chain 7 actuating cam 22 is displaced in drive rod longitudinal direction L. This actuating cam 22 operates on a control surface 23 of the locking lever 17 in such a way that the locking lever 17 is pivoted about the axis of rotation 24. This results from a comparative analysis of the Fig. 4 and 5 , The locking lever 17 now has a fork receptacle 25, in which engages a connected to the central bolt 6 mandrel 26. The locking lever 17 thus sets a linear displacement of the central lock chain 7 in the drive rod longitudinal direction L in a displacement of the central bar 6 along the locking direction V which is orthogonal to the drive rod longitudinal direction L. A comparative analysis of the Fig. 4 and 5 makes it clear that in this way the central bolt 6 from the unlocked position ( Fig. 4 ) in the locking position ( Fig. 5 ) is transferred, so that all closing elements are excluded when closing the door. It is therefore first of all important that in the course of the closing of the door all locking elements of the central lock on the one hand and additional locking on the other hand are automatically excluded. The self-release is preferably realized with a trigger magnet. However, the invention also includes embodiments in which the self-release mechanically, z. B. is realized by triggering a latch in the additional lock. Incidentally, the invention also includes such embodiments in which the self-triggering is not initiated by the additional latches and then transferred to the central lock, but in which, conversely, the self-initiation initiated via the central lock and then transferred to the additional latches or in which locks each locking unit independently becomes.

In deviation from the known lock according to DE 20 2009 007 674 U1 or for its further development, in the case of the lock according to the invention shown in the figures, the lock nut 8 is designed as a split lock nut with a first nut half 8a and a second nut half 8b. The first nut half 8a is assigned to the outside of the door, while the second nut half 8b is assigned to the inside of the door. In the nut halves z. B., not shown, push pin of an inner door handle and an outer door handle engage. It can alternatively or additionally also other fittings, for. B. rod fittings, in particular be provided on the inside of the door, which then also work on the lock nut or the lock nut halves. Rod fittings are often used on the inside of the door as an alternative or supplement to pushers for easy panic unlocking. The lock nut 8 with its nut halves 8a, 8b now serves not only in a known manner the retraction of the latch 5, but - since all locking elements are always excluded in the course of the closing of the door - via the lock nut 8 and a retraction of all locking elements, namely the Central bar 6 and the additional bolt 11. For this purpose, the two lock nut halves 8a, 8, with the central lock chain 7 in operative connection. In the exemplary embodiment, the lock nut halves 8a, 8b are each provided with an actuating arm 28 which operates against a corresponding actuating surface 28 'of the central lock chain 7. For example, if the lock nut according Fig. 5 Turned counterclockwise, so pushes the actuator arm 28, the central lock chain 7 upwards, so that then not only the central bolt 6 is withdrawn, but also on the drive rods and the auxiliary lock chain and the additional bolt. In addition, the latch 5 is then retracted in the course of the movement in a conventional manner. This works at the in Fig. 5 shown Functional position equally from the inside of the door as well as from the outside of the door.

If the door is now to be secured against unauthorized access from the outside, then this backup takes place via the (not shown) lock cylinder, which is inserted into the lock cylinder receptacle 9. Such a lock cylinder has a closing nose 27, which is merely indicated in the figures. The mode of operation results from a comparative analysis of the Figures 5 and 6 , Fig. 5 shows the locked central lock with locked latch, but in the unsecured working position while Fig. 6 the central lock then shows in the secured functional position in which access from the outside is prevented. For the central lock according to the invention is provided with a blocking lever 29 which is operable with the lock cylinder, or with its closing lug 27 for the purpose of blocking the first half-lock nut 8a. A comparative analysis of the Fig. 5 and 6 , shows that in the course of the operation of the lock cylinder, the lock lever 29 is displaced along the drive rod longitudinal direction L, in Fig. 5 up. The blocking lever 29 then passes into the functional position according to Fig. 6 in which he blocks the first half-lock nut 8a. For this purpose, the lock nut half 8a is provided with a blocking stop 32, which cooperates with the blocking end 33 of the blocking lever 29. The above-described rotation of the lock nut for the purpose of unlocking is consequently prevented by the blocking lever 29, since the blocking stop 32 abuts against the blocking end 33 of the blocking lever 29. Of particular importance is the fact that the blocking lever 29 only on one of the lock nut halves, namely on the "outer" Schlossnusshälfte 8a has influence. In the in Fig. 6 shown secured functional position, the lock can therefore on the first half-lock nut 8a and consequently no longer open from the outside, as a release is completely blocked.

From the inside of the door and consequently the second half of the lock nut 8b, it is still possible to open it in the manner described, since the blocking lever 28 blocks only the half-lock nut 8a, but not the half-lock nut 8b. Although the lock nut half 8b may likewise have a blocking stop 32, the blocking lever does not protrude into the area of this blocking stop 32 of the second lock nut half 8b. Consequently, a perfect panic function is realized, because even in the locked and secured functional position, the door lock can always be easily opened from the inside, namely by handle operation or fitting operation and consequently by turning the lock nut half 8b.

Of particular importance in this case is in particular the fact that such panic unlocking via the lock nut half 8b has no influence on the securing position of the blocking lever 29. After a Panikentriegelung and opening the door of the door falls back into the frame, so that all locking elements are automatically excluded in the manner described. Since the blocking lever 29 has remained in its blocking position during the entire process, the door is then again in the locked and secured functional position even after a panic opening. The blocking and securing is very easy on the lock cylinder, with only the locking lever 29 and possibly a locking lever 30 described below must be manipulated. In particular, can be dispensed with a change lever in the context of the invention to a "change function". Change function usually means the possibility to retract the lock latch on the lock cylinder. As is used in the present case with a split locknut and thus the lock is actuated both from the inside of the door and the outside of the door via a pusher or the like fitting is a change function is not required. The lock cylinder consequently serves in the context of the invention preferably exclusively for blocking the first lock nut half 8a via the blocking lever 29.

It is in the Fig. 5 and 6 recognizable that the blocking lever 29 can be locked by means of a locking lever 30 in the blocking position (see. Fig. 6 ). The locking lever 30 is pivotally mounted in the lock housing 10. The locking lever can be pressed by means of spring force of a locking spring, not shown, and possibly by means of gravity in the locking lever 29 arresting blocking position. The spring force is indicated by the arrow 31. In this case, the blocking lever 29 may have a locking nose 34 which cooperates with the blocking surface 35 of the locking lever. In Fig. 6 It can be seen that the blocking lever is secured by interaction of locking lug 34 and locking surface 35 against displacement down.

Furthermore, it can be seen in the figures that the blocking lever 29 has a first actuating surface 36, against which the lock cylinder or the closing nose 27 operates in the course of blocking. Furthermore, a second actuating surface 37 is provided, which operates the locking lug 27 in the course of release.

To get the blocking lever out of the in Fig. 5 shown release position in the in Fig. 6 To bring shown secured position, the lock cylinder is rotated clockwise, so that the locking tab 27 operates against the actuating surface 36 and pushes the blocking lever along the drive rod longitudinal direction L (up). The blocking lever 29 then enters the Fig. 6 shown secured functional position. In order to be able to open the lock again from the outside, the lock cylinder - starting from the functional position Fig. 6 - Turned counterclockwise, so that the locking lug 27 works against the second actuating surface 37. In this case (also) the locking lever 30 is pivoted by the locking lug 27 operates against the actuating surface 38 of the locking lever 30, so that the locking lever 30 releases the locking lever 29. Then, by turning the locking lug 27, the blocking lever 29 can be displaced in the drive rod longitudinal direction L (downwards), so that the first half-lock nut 8a is released again and then opening of the door via the pusher is possible both from the outside and from the inside.
