The Fig. 1 to 7 show an exclusively mechanically actuated door lock 1, which is intended as a door lock for so-called panic doors. The Door lock 1 is prepared for the use of sensors arranged on a circuit board as well as electrical actuators.

Door locks for panic doors are designed so that they allow in the event of danger leaving a closed by the panic door space by manual operation of a handle from the inside of the room, even if the door lock 1 is locked. The door lock 1 has a face plate 2, which is provided for fastening the door lock 1 on the front side of the panic door (see Fig. 1 and 2 ). The door lock 1 can be used both for the wing of a single-leaf door and for the active leaf of a two-leaf door. The door lock 1 comprises a lock mechanism with a bolt 3, a latch 4, an auxiliary latch 5, a lock nut 6 and a lock cylinder 7. The latch 3, the latch 4 and the auxiliary latch 5 can be moved between a pre-closed position and a back-closed position become. In their pre-closed positions, the bolt 3, the latch 4 and the auxiliary latch 5 project out of the forend 2 from an opening assigned to them. In their back-locked positions of the bolt 3, the latch 4 and the auxiliary latch 5 are retracted into the lock case. The door lock 1 is designed as a self-locking lock. This means that the bolt 1 automatically extends into a vorgeschlossene, the door lock 1 locking position when the door has reached its closed position on the stationary door frame or the inactive leaf. The automatic extension of the bolt is controlled by the auxiliary latch 5 and the latch 4.

The lock nut 6 comprises a first outer nut 6a and a second outer nut 6b. At the outer nuts 6a and 6b is in each case a handle connected, with the respective outer nut 6a, 6b can be rotated manually. However, embodiments are also possible in which only one of the two outer nuts 6a, 6b has a handle connected to it. In this case, a handle for manual operation is provided only on one side of the wing. The handle is then provided on the side facing the interior of the wing. On the opposite side of the wing then a non-rotatable knob is present.

The bolt 3 can be actuated by a bolt slide 8, wherein the bolt 3 is coupled via a sliding gear with the bolt slide 8. The bolt slide 8 has a Z-shaped link 8k, in which a pin 3z rigidly connected to the bolt 3 slides. The locking slide 8 is designed to be displaceable parallel to the longitudinal axis of the forend 2. Since the actuation direction of the bolt 3 is perpendicular to the longitudinal axes of the end portions of the link 8k, the bolt 3 is no longer displaceable when the pin 3z of the bolt 3 in a the two end portions of the gate 8k is arranged. As soon as the pin 3z enters the oblique center section of the gate 8k by displacing the bolt slide 8, the bolt 3 is retracted or extended into the forend 2 until it again enters an end section of the gate 8k and is thus locked.

The bolt slide 8 can be actuated both by the lock cylinder 7 and by the lock nut 6.

The lock cylinder 7 engages with its center portion of the door lock 1 and with its end portions opposing receptacles in the door leaves of the panic door. Trained as a one-armed lever core 7k of the Locking cylinder 7 is pivotable by key engagement about the longitudinal axis of the lock cylinder 7, wherein the end portion of the core 7k cooperates with the locking slide 8, such as in Fig. 6 is recognizable. As soon as the core 7k is rotated by inserting a suitable key into the lock cylinder 7 (in FIG Fig. 6 in the clockwise direction), the bolt slide 8 is raised, so that the pin 3z of the bolt 3 enters the oblique center portion of the link 8k, the bolt 3 is retracted into the forend 2 until the pin 3z enters the other end portion of the link 8k and thus the bolt 3 is locked in the retracted position in the forend 2.

The outer nuts 6a, 6b of the lock nut 6 cooperate with slide-shaped coupling elements, wherein the first outer nut 6a cooperates with a first coupling element 9a and the second outer nut 6b with a second coupling element 9b. The coupling elements 9a, 9b are by compression springs 9f (see Fig. 3 to 6 ), which are supported on a housing of the door lock 1, pressed into an upper end position. The coupling elements 9a, 9b, like the locking slide 8, are designed to be displaceable parallel to the longitudinal axis of the forend 2 and have, as in FIG Fig. 3a shown, a coupling recess 9k, in which engages a arranged on the rear outer circumference of the outer nut 6a, 6b driver 6m. By rotating the outer nut 6a, 6b, the associated coupling element 9a, 9b is pressed down against the spring force of the compression spring 9f from its upper end position.

Between the two coupling elements 9a, 9b, a transmission element is arranged, which is designed as an intermediate slide 10, which cooperates via a pivotable coupling member 11 with the locking slide 8. The Intermediate slide 10 is selectively rigidly connectable to the first coupling element 9a or to the second coupling element 9b. As connecting elements connecting screws 12 may be provided which engage in the intermediate slide 10 by cross threaded holes. The length of the threaded portion of the connecting bolts 12 is dimensioned so that the threaded portion is longer than the strength of a coupling element and smaller than the strength of a coupling element plus the thickness of the intermediate slide 10. Thus, it is possible to determine during assembly of the door lock 1, whether the latch 3 can be actuated via the first outer nut 6a or the second outer nut 6b. In the in the Fig. 1 to 6 illustrated embodiment, the first outer nut 6a cooperating with the first outer coupling element 9a is rigidly connected to the intermediate slide 10. Will now have one in the FIGS. 1 to 6 handle, not shown, the outer nut 6a is actuated, the latch 3 is retracted independently of the closed state of the lock cylinder 7 in the forend 2, so that the panic door can be opened. The door lock 1 can then be unlocked at any time by actuating the handle connected to the outer nut 6a. This side of the wing is usually associated with the inside of the building facing side of the wing. From the opposite side, ie from the outside of the building, the door lock 1 can be locked only with the help of the lock cylinder. This means that z. B. in case of danger, the door lock can be unlocked at any time from the inside of the building by pressing the handle. From the outside of the building, the door lock 1 can only be unlocked by authorized persons who are in possession of a corresponding key. In practice, the inside of the building is also called a panic page.

The Fig. 7a and 7b show a variant of in Fig. 1 to 6 described door lock 1, in which a modified intermediate slide 10 is inserted. At the intermediate slide 10, a pawl 10s is rotatably mounted, which is on and auskoppelbar. The pawl 10s is brought into the disengaged state by a return spring 10sf. The return spring 10sf is formed as a compression spring and arranged between pawl 10s and the intermediate slide 10. The pawl 10s connects in the coupled state, the first coupling element 9a and / or the second coupling element 9b at least in a direction of movement, preferably in the unlocking, firmly with the intermediate slide 10. The pawl 10s engages behind for coupling to the first coupling element 9a and / or the second Clutch 9b trained undercut 9h. It can also be provided that the pawl 10s engages for coupling into a groove formed on the first coupling element 9a and / or the second coupling element 9b. It is thus possible to realize an access function of an authorized person by connecting the coupling device for coupling the intermediate slide 10 with the first coupling element 9a and / or the second coupling element 9b and for decoupling the intermediate slide 10 of the first coupling element 9a and / or of the second coupling element 9b triggers. Similarly, the panic door in case of danger, for example, in the event of a fire, automatically unlocked.

In the in Fig. 7a and 7b illustrated embodiment, the pawl 10s is actuated by a Schließzylinderzug 7z. The Schließzylinderzug 7z is operated via the lock cylinder. The lock cylinder is decoupled in this embodiment of the bolt, so that upon rotation of the lock cylinder, the bolt is not locked or unlocked. Rotation of the lock cylinder causes rotation of the lock cylinder train. The Schließzylinderzug 7z is as a formed two-armed lever which is mounted in the housing of the door opener 1. In the Fig. 7a and 7b is a bearing axis 7zl located around which the Schließzylinderzug 7z is pivotable. The one lever arm of the Schließzylinderzugs 7z has a switching cam 7zs on with a straight portion which merges into a circular arc, the other lever arm has at its end portion a switching lug 7zn, which rests in the coupled state on the pawl 10s.

Upon actuation of the lock cylinder 7, the core 7k of the lock cylinder slides along the shift cam 7zs. He exerts a force on the first lever arm of the Schließzylinderzugs 7z, which pivots the Schließzylinderzug 7z in the direction of the pawl 10s, so that the pawl 10s enters the coupled state. A bistable coil spring 7zf engaging the end portion of the other lever arm holds the lock cylinder cable 7z either in the coupling position or in the decoupling position.

The 8 and 9 show a second embodiment of the door lock according to the invention, which on the in Fig. 1 to 7 builds up the described principle of action.

The door lock 1 has optical sensors L1 to L7 and Hall sensors H1 and H2, which are arranged on a circuit board 16. On the board 16 an electronic evaluation device 17 is further arranged, which generates a specific output signal by a logical evaluation of at least two sensor signals and stores this particular output signal and / or outputs via an interface. The structure of the board 16 is described below in Figs. 13a and 13b.

The optical sensors L1 to L7 are designed as bifurcated light barriers, which are switchable by a slide switch. When the slide switch is immersed in the photocell, the photocell is actuated, i. the optical sensor is active. If the slide switch is not immersed in the light barrier, the light barrier is inoperative, i. the optical sensor is inactive.

An auxiliary case sensor L6 cooperates with a switch 5s arranged on the auxiliary latch 5. A door contact sensor L7 cooperates with a switch 15s arranged on the door contact 15.

The electronic evaluation device 17 generates an output signal "Türzustandssabotage" when at the same time the signal of the auxiliary case sensor L6 is present and the signal of the door contact sensor L7 is not present or if at the same time the signal of the auxiliary case sensor L6 is not present and the signal of the door contact sensor L7 is present.

The electronic evaluation device 17 generates an output signal "door open" when at the same time the signal of the auxiliary case sensor L6 is present and the signal of the door contact sensor L7 is present.

The electronic evaluation device 17 generates an output signal "door closed" when at the same time the signal of the auxiliary case sensor L6 is not present and the signal of the door contact sensor L7 is not present.

Furthermore, the door lock 1 has a first slide sensor L3, a second slide sensor L4 and a third slide sensor L5, which can be switched by a switch slide 8s arranged on the latch slide 8. The slider sensors L3 to L5 are arranged in the direction of movement of the slide valve 8s one behind the other and spaced from each other on the circuit board 16. The slide switch 8s is designed to co-operate with a maximum of two of the three slide sensors L3 to L5. Since the bolt 3 is motion-coupled to the bolt slide 8 by a link gear, describe the signals of the slide sensors L3 to L5, the position of the bolt. 3

The electronic evaluation device 17 generates an output signal "latch retracted" when at the same time the signal of the first slide sensor L3 is present and the signals of the second slide sensor L4 and the third slide sensor L5 not present.

The electronic evaluation device 17 generates an output signal "latch extended" when at the same time the signal of the third slide sensor L5 is present and the signals of the first slide sensor L3 and the second slide sensor L4 are not present.

The electronic evaluation device 17 generates an output signal "bar partially extended" when at the same time the signal of the first slide sensor L3 and the third slide sensor L5 is not present and the signal of the second slide sensor L4 is present.

Next, the door lock 1 on a Nusssensor L1, with the lock nut 6 for detecting a movement of a in Fig. 7 and 8th Not shown and designed as an external handle handle cooperates. With the Nusssensor L1, a switching slide 9s cooperates, which is connected to the second coupling element 9b. As in the in Fig. 7 and 8th illustrated embodiment, the second outer nut 6b is coupled to the second coupling element 9b, is moved linearly upon rotation of the second outer nut 6b of the slide switch 9s.

The door lock 1 further comprises a bolt sensor L2, which with the lock nut 6 for detecting a movement of a in Fig. 7 and 8th not shown and designed as an internal handle handle cooperates. With the bolt sensor L2 acts a slide switch 9as, which is connected to the first coupling element 9a. As in the in Fig. 7 and 8th illustrated embodiment, the first outer nut 6a is motion-coupled to the first coupling element 9a, 9a is moved linearly upon rotation of the first outer nut 6a of the slide switch.

The electronic evaluation device 17 generates an output signal "panic function" when at the same time a signal of the Nusssensors L1 and a signal of the bolt sensor L2 and the signal of the third slide sensor L5 is not present.

The electronic evaluation device 17 generates an output signal "outside handle unauthorized actuated" when at the same time a signal of the nut sensor L1 is present and a signal of the bolt sensor L2 is not present.

The electronic evaluation device 17 generates an output signal "cylinder contact", if at the same time a signal of the Nusssensors L1 and a signal of the bolt sensor L2 is not present and a signal of the third slide sensor L5 is present.

The door lock 1 has a coupling device for coupling the two handles, which comprises an electric control motor 13, a helical gear 13s and a clutch lever 13k. The output shaft of the electric control motor 13 is rotationally rigidly connected to the helical gear 13s, which acts on a first leg of the bell crank 13k designed as an angle lever. A second leg of the clutch lever 13k cooperates with a pawl 10s, which is rotatably mounted on the intermediate slide 10. The pawl 10s connects in the coupled state, the first coupling element 9a and / or the second coupling element 9b at least in a direction of movement, preferably in the unlocking, firmly with the intermediate slide 10. The pawl 10s engages behind for coupling to the first coupling element 9a and / or the second Clutch 9b trained undercut 9h. It can also be provided that the pawl 10s engages for coupling into a groove formed on the first coupling element 9a and / or the second coupling element 9b. It is thus possible to realize an access function of an authorized person by the trained as an electric motor coupling device 13 for coupling connects the intermediate slide 10 with the first coupling element 9a and / or the second coupling element 9b and for decoupling the intermediate slide 10 of the first coupling element 9a and / or released from the second coupling element 9b. For this purpose, an access control, for example a reading unit for reading out an identification chip, is provided on the door leaf or on the door frame. When an authorized identification chip is read out, the coupling device designed as an electric motor 13 is then activated, which actuates the pawl 10s. Because of the clutch is the lock can then be unlocked manually from both sides of the wing by actuating the respective handle. Independently of the coupling device, the lock can be unlocked manually by actuating the handle from the inside of the building. In addition, the door lock can always be unlocked by pressing the lock cylinder with the appropriate key. This means that from the outside of the building, the door lock 1 can only be unlocked by authorized persons, who are in possession of a corresponding key or a corresponding identification chip, by actuation of the lock cylinder or by actuation of the external handle.

In the region of the helical gear 13s, a first position sensor H1 and a second position sensor H2 are arranged. The position sensors H1 and H2 are designed as Hall sensors, which are connected by a arranged on the output of the helical gear 13s permanent magnet. The position sensor H1, H2 is active or actuated when the permanent magnet is above the position sensor H1, H2. The position sensor H1, H2 is inactive or inoperative when the permanent magnet is not above the position sensor H1, H2.

The electronic evaluation device 17 generates an output signal "outer handle coupled" if at the same time a signal of the first position sensor H1 is not present and a signal of the second position sensor H2 is present.

The electronic evaluation device 17 is connected to the electric control motor 13 and has a timer, which is set by the output signal "external handle coupled". At the end of the timer, the controlled electrical control motor 13 for decoupling the two connected by the coupling device handles.

The 10 and 11 show a third embodiment of the door lock. 1

The door lock 1 is like the one in 8 and 9 described door lock, with the difference that the door lock 1 is designed as a motor lock and instead of the board 16, a board 16 'is provided. Also, this third embodiment of the door lock 1 is designed as a self-locking door lock. The unlocking can be done in different ways. The lock is unlocked on the one hand by actuation of the drive motor 14. Independently of the drive motor 14, the lock can be unlocked manually at any time by actuating the handle from the inside of the building. In addition, the door lock can always be unlocked by pressing the lock cylinder with the appropriate key.

An electric drive motor 14 is provided which actuates the latch 3 via a cam disc 18. The cam disk 18 has at its end face a cylindrical contact piece 18 s, which in a rotation of the cam disc 18 by about 180 ° in the clockwise direction from its in Fig. 9 and 10 illustrated starting position the bolt slide 8 lifts and thereby pulls the bolt 3 in the forend 2. After this rotation, the switch piece 18s is in an upper position, and the door can be opened. The position of the switching piece 18s is transmitted via a two-armed cam lever 19, wherein the cam lever 19 at its cam lever 18 facing away from the lever arm has a switching piece 18s, which cooperates with a motor position sensor L8. The engine position sensor L8 is electrically connected to the electronic evaluation device 17.

A bolt sensor L2 'acts like the one in Fig. 7 and 8th described bolt sensor L2 with the lock nut 6 for detecting a movement of a in Fig. 9 and 10 not shown and designed as an internal handle handle together. The movement is transmitted via a pivot lever 20 mounted in the bearing of the cam lever 19. The pivot lever 20 has at its end remote from the bearing on a switching piece 20s, which cooperates with the bolt sensor L2 '.

3. Lock according to claim 1 or 2,
   characterised in that
   the first outer follower (6a) is movement-coupled to the first coupling element (9a) and the second outer follower (6b) is movement-coupled to the second coupling element (9b) via a positive connection, preferably a transfer of a rotational movement from the first outer follower (6a) to the first coupling element (9a) and from the second outer follower (6b) to the second coupling element (9b) takes place via a positive connection.
4. Lock according to claim 3,
   characterised in that
   the first outer follower (6a) has a driver (6k) which engages positively into a recess (9k) of the first coupling element (9a), and the second outer follower (6b) has a driver (6k) which engages positively into a recess (9k) of the second coupling element (9b).
5. Lock according to one of claims 3 or 4,
   characterised in that
   the first coupling element (9a) has a driver which engages positively into a recess of the first outer follower (6a), and the second coupling element (9b) has a driver which engages positively into a recess of the second outer follower (6b).
6. Lock according to one of the preceding claims,
   characterised in that
   the multi-part follower is formed as a two-part follower.
7. Lock according to one of the preceding claims,
   characterised in that
   the gear element (10) is arranged between the first coupling element (9a) and the second coupling element (9b).
8. Lock according to one of the preceding claims,
   characterised in that
   the lock housing has a housing base and a housing cover, and the housing base and/or the housing cover has or have guides or receptacles for supporting the first coupling element (9a) and/or the second coupling element (9b).
9. Lock according to one of the preceding claims,
   characterised in that
   the first coupling element (9a) and the second coupling element (9b) are slidably supported running in parallel to each other on the housing base and/or on the housing cover.
