EP3045623B1 - Safety device for a door - Google Patents

Description

The invention relates to a security device for securing a door or a window in a building with a lock according to the features of the preamble of claim 1.

Such a safety device is from the DE 10 2011 051 952 A1 known. There is shown a panic lock with a latch bolt and a control device. The lock can be switched to a release state or a locked state via the control device. The lock can be opened in the release state, whereas in the locked state the lock is locked and protected against manipulation.

A conventional, electrically operated lever lock, which has a panic function B, is in the locking position (starting position) as follows: bolt extended, on the panic opposite side, follower nut coupled, panic side lever follower engaged, latch extended, respectively. Tilt traps rigid. If the handle is now pressed on the opposite side of the panic when the door is inspected before an electrical opening impulse occurs, for example via an access control device, the door cannot be opened while the handle is still pressed. To open the door, the handle must now be released first, resp. be pulled up to engage the follower nut by pressing the trigger again. Consequently In this case, a two-handed movement is absolutely necessary to inspect the door.

Such handle locks are well known on the market. However, when the handle is operated before the electric opening pulse is triggered, these always require a new handle movement (two-hand movement) to open the door. This type of operation (two-hand movement), which was previously necessary in this constellation (opening signal when the button was pressed) corresponds to the current state of the art.

The invention has for its object to make access to a building, which is secured by a lock, at the same time as comfortable as possible with high security against burglary. Preferably, easy access, in particular barrier-free access, should be made possible.

This object is achieved according to the invention by a safety device with the features of claim 1 and by a method with the features of claim 11.

According to the invention, it is provided that the handle sensor has an external sensor which interacts with the outer nut and the control device is designed such that in the closed position and when the outer nut is uncoupled, it moves the lock bolt into the day position after receipt of an opening impulse and then the drive motor for moving the Activates the lock bolt and / or the lock latch into the open position if, after reaching the day position, the outside sensor detects an actuation of the outside handle, or the outside sensor detects that one Operation of the outside handle continues. The lock can thus be opened even if the outside handle has already been actuated before the opening impulse has been generated, for example, by a transponder. This allows one-hand operation, so to speak, without the need to let go of the outside door handle again.

It is also provided that when the outer nut is uncoupled, the locked lock is opened by first generating a first opening impulse based on correct access authorization in order to move the lock bolt from the closed position into the day position via the drive motor and in a second step Step when actuating the outside handle via the handle sensor, a second opening pulse is generated in order to move the lock bolt and / or the latch into an open position by motor. This enables an authorized person to gain access to a building when it is locked from the outside, since after reading in or entering a correct access authorization, it is only necessary to press the outside handle once to completely unlock the access.

It is provided that in the second step the second opening pulse is generated or generated via an outside sensor of the handle sensor, which cooperates with the outer nut to detect a handle movement. It is advantageous if the second opening pulse is generated in the second step regardless of whether the outside handle was pressed before reaching the day position or only after the day position was reached.

Furthermore, it can be provided in one embodiment that in a third step after reaching the open position, a door drive for opening the door and / or the window, in particular for moving a door leaf or a window leaf, is actuated into an open position.

It can be provided that the simplified access according to the invention can be realized with panic locks with panic function B. With panic function B, the lock automatically locks access when the sash is closed. In this closed position, the door can always be opened from inside the secured room or the building using the inside door handle. This corresponds to the panic function. By unlocking with a key, or by entering a correct access authorization, for example in the form of an access code, or by reading a wireless transponder or RFID chip that sends out an access code that is read in and verified by a reading device, the panic function B will Outside door handles located on the outside are engaged so that access is also possible from the outside.

A problem arises if the outside door handle is operated before the correct access authorization has been entered. Then the outside nut is already turned by the outside door handle and can usually no longer be properly engaged. The present invention circumvents this problem in that, after inputting or reading in a correct access code or signal, a sensor signal connected to the outside nut or the outside door handle is queried and the lock is opened by a motor when the outside handle is actuated. It is a combination of the handle lock function with a motor lock, so to speak.

The device according to the invention and the method according to the invention can also be used for a panic function E. With panic function E, access is also automatically blocked by a lock when the door is closed. The locked door can always be opened from the inside using a lever handle. In the event of panic, this ensures that the secure building or the secure room can be left. The outside handle is usually permanently uncoupled from panic function E. With conventional locks with panic function E, outside access is only possible for one authorized person with a key. In addition to access with a key, the present invention also enables convenient access with a one-hand function in the case of a panic E function, since no key has to be turned, but it is sufficient, after reading in a correct access code, for example via a transponder or one RFID chip or entering a number code to actuate the outside door handle. This enables a panic function E to be implemented as a barrier-free passage.

An opening pulse can be understood to mean, for example, a control command from a bus system or a higher-level control device. A pulse generated by a sensor or switching contact or a contact signal from a switch, preferably an N / O (normally open) or N / C (normally closed) switch, can also be understood.

It can be provided that the opening pulse is generated via a reading and / or input device by the reading and / or input device reading or verifying an access code. For example, the reading and / or input device can wirelessly read a code of a transponder or an RFID tag, with a person authorized to access the Holds transponder or the RFID tag for reading in front of the reading and / or input device. The reading and / or input device can also be arranged at a central point in a building, for example at a gatekeeper, and send an opening impulse to the lock or to the control device of the lock on the basis of a release by the gatekeeper. In the simplest case, the reading and / or input device can be designed as an opening button connected to the control device.

Open position is understood to mean a position of the lock bolt and the lock latch retracted into the lock housing. In the open position, the door can be freely walked on and the door leaf opened. When using a lockable tilt latch or cross latch, the latch is unlocked in the open position.

The day position is understood to mean that when the door leaf is in the closed position, the lock bolt is already partially drawn into the lock housing and the lock latch is locked, i.e. locks the door leaf by engaging in a latch recess of a striking plate.

The closed position in the closed position of the leaf is understood to mean that the lock bolt is completely excluded and engages in a lock bolt receptacle in a striking plate on the frame, and the lock latch is locked to lock the leaf of the door in the closed position.

The lock preferably has an open position with a bolt element drawn into the lock housing, a day position with a reduced bolt exclusion, in particular a bolt exclusion in the range from 3 mm to 8mm, and a closed position with complete bolt exclusion, in particular a bolt exclusion in the range from 10mm to 22mm.

A lock nut with an inner nut and an outer nut is used as the lock nut. The outer nut can be coupled and uncoupled. In one configuration, the inner nut can be permanently connected to the lock mechanism. In one embodiment, the inner nut can also be designed as a nut part that can be coupled and / or uncoupled. Coupling means that a door handle engaging in the respective half of the nut is connected to the lock mechanism in order to pull the latch and / or the bolt back into the lock housing when the door handle is actuated. Uncoupling means that the lever handle that engages in the respective half of the nut is uncoupled from the lock mechanism, so that when the lever handle is actuated, the lock bolt or the latch bolt is not actuated.

The lock's access authorization can be generated, for example, using a key switch or a code keyboard and entering a correct access code. To ensure comfortable access, it can be provided that the access authorization is generated via a contactless transponder and / or the entry of an access code and / or the reading out of a data carrier. Using a wireless transponder or an RFID chip, access authorization can be recognized over a certain distance from the reader and the lock can therefore already be switched to the day position. A separate manual entry of an access authorization can thus be omitted.

In one embodiment it can be provided that the lock has a slide plate driven by the drive motor, which is connected to the lock bolt and moves it between the open position and the day position and the closed position. The locking elements of the lock, i.e. the lock bolt, and the lock latch can be actuated by motor via the drive motor. That Both the lock bolt and the lock latch can be drawn into the lock housing via the drive motor.

It can also be provided that the lock is designed to be electrically self-locking in that the lock has a closed position sensor connected to the drive motor. When the door leaf is closed, the closed position sensor reports that the door leaf is in the closed position, whereupon the control device of the lock controls the motor to lock the lock bolt and / or the lock latch.

In one embodiment, it can be provided that the slide plate is connected to the lock latch or a latch locking device and actuates it in order to switch or actuate the lock latch between the open position and the day position and the closed position.

In order to enable precise control of the lock, it can be provided that the lock has a bolt sensor connected to the control device for detecting a bolt position. The slide plate has a switching lug which interacts with the bolt sensor. A position of the lock bolt can be determined via the bolt sensor. For example, it can be determined whether the lock bolt is in the closed position, ie in the long excluded position. It can also be detected whether the lock bolt is in the day position. It can also be detected via the bolt sensor whether the bolt sensor has been completely retracted into the lock housing, that is to say is in the open position.

In one embodiment, it can be provided that the bolt sensor is designed as a microswitch and the switching flag extends perpendicular to the surface of the slide plate and is designed as a spring or has a resilient section. The switching flag can preferably be designed as a leaf spring or helical spring.

In one embodiment it can be provided that the lock is designed as a main lock without multiple locks. This means that no additional locking devices are connected to or actuated by the lock.

It can also be provided that the lock is designed as a lock with multiple locks. In this case, for example, the slide plate can actuate one or more additional locks via a drive bolt rod or a plurality of drive bolt rods. The additional locks can be integrated in a door leaf and arranged on the faceplate of the lock. The additional locks can, for example, also be integrated in a door leaf and designed as a top lock or bottom lock.

For an exact query of a door handle actuation, it can be provided in one embodiment that the handle sensor has two microswitches, the first microswitch being designed as an internal sensor and with the inner nut and the second microswitch is designed as an outer sensor and interacts with the outer nut. Both the actuation of the outside handle and the actuation of the inside handle can be recorded separately.

In order to enable the trigger sensor to respond over a certain actuation range, it can in particular be provided that the trigger sensor has a shift fork with two resilient switching tongues arranged between the microswitches and the lock nut. The resilient tongues extend along the outer contour of the follower and thus bridge a certain angle of rotation of the respective nut part. This makes it possible that the handle sensor triggers prematurely both at relatively small angles of rotation of the outside door handle and also remains reliably triggered when the angles of rotation of the door handle increase further. For example, a rotation angle range of the lever handle from 5 ° to 60 ° or preferably 70 ° can be covered.

In an advantageous embodiment it can be provided that the two resilient switching tongues are connected to one another at one end and project freely at the other end between the microswitch and the lock nut.

In order to keep the wiring and installation effort low, it can be provided that the lock has a bus interface and the control device and / or the reading and / or input device are connected via the bus interface. The bus interface can be designed as a serial bus interface in order to connect the lock or the control device to a central control unit via a serial bus. and / or to connect the evaluation unit. The reading and / or input device for reading and / or entering an access authorization can also be connected to the lock or the control device of the lock via a bus, in particular a serial bus.

In an alternative embodiment it can also be provided that the lock is to be wired conventionally. i.e. Discrete cable connections are provided for connecting the lock or the control device, wherein one wire of the cable connection transmits a single switching signal or a single sensor signal.

In order to further improve the barrier-free passage, it can in particular be provided that the securing device comprises a wing of a door or a window that can be opened by a drive, and the control device controls the drive to open the wing after the lock is in the open position. The door is opened automatically via the door drive. This means that manual opening of the door or door leaf can be completely omitted. This enables barrier-free access to be created for physically disadvantaged people.

In the figures, an embodiment of the invention is shown, in which the same components are provided with the same reference numerals. The Fig. 1 shows a securing device 9 with a door 91 with a door leaf 92 rotatably mounted on door frames 91r via door hinges 92a, 92b. The door leaf 92 has on its closing edge a mortise lock 8 which can be actuated via a door handle 94. About the lock 8 can Door leaf 92 are locked in the closed position to ensure access. A door drive 95 is arranged on the upper side of the door leaf 92 in order to open or close the door leaf in a motor-driven manner. In the area of the door lock, a reading and / or input device 93 is arranged on a wall of the building in order to read in an access authorization wirelessly, for example via a transponder.

In the Figures 2-5 the mortise lock 8 is shown with the lock cover removed. The mortise lock 8 has a lock case 81, in which locking elements, namely a lock bolt 1 which excludes two turns and a lockable tilt latch 3 are arranged. A receptacle for a lock cylinder is arranged in the lower area of the lock case. In the upper area the lock case has a drive motor 83 which is controlled by a control device 41 in order to actuate a central slide plate 84 of the lock. The central slide plate 84 can be moved parallel to a lock face plate 82 in order to actuate the locking elements tilt latch 3 or lock bolt 1.

The mortise lock 8 is designed as a self-locking panic lock. It has a spring-loaded mechanism that is loaded when the lock is unlocked. A closing of the door is detected via a control latch 31 and the tilt latch 3, wherein after the door leaf has been moved into its closed position, the lock bolt 1 automatically excludes two turns, that is to say in FIG Fig. 2 shown closed position is moved out of the lock housing. At the same time, the tilt latch 3 is blocked, so that in the Fig. 2 shown closed position, the lock 8 locks the door securely.

In the Fig. 3 the lock 8 is shown, wherein in the representation of the Fig. 3 the lock nut 2 or its outer nut part 2a is actuated via an outside door handle, not shown. The locking elements 1 and 3 are in the representation of the Figure 3 still in the closed position. That is, the lock bolt 1 is extended in two revolutions and the tilt latch 3 is locked, ie switched rigid.

In the Fig. 4 the lock 8 is shown after an opening pulse has been received by the control device 41 via the bus interface 4. The opening pulse was generated after a correct access code had been entered via the reading and / or input device 93. As a result of the opening impulse, the control device 41 has actuated the motor 83 in such a way that it has moved the lock bolt 1 into its day position, that is to say into the single-position excluded position, via the slide plate 84. The in the Figure 4 The day position shown comprises the lock bolt 1 in its partially closed position, ie the lock bolt 1 protrudes from the lock housing by approximately 5 mm. The tilt latch 3 is still locked in the day position, ie switched rigid.

In the Fig. 5 the open position of the lock 8 is shown. After reaching the in Fig. 4 shown day position, the outside lever, not shown, is still actuated. The lock nut 2 or its outer nut part 2a interacts with the control device 41 via the pusher sensor 5. By the in the representation of the Fig. 5 A push button 5 generates a second opening pulse, which is still continuously operated. On the basis of the second opening pulse, the control device 41 controls the electric drive motor 83 to fully open the lock 8. The lock bolt 1 is then fully inserted into the lock 8 and the tilt latch 3 is unlocked.

In the Fig. 6 an enlarged detail is shown in the area of the lock nut 2 with the pusher sensor 5. The lock nut 2 has an outer nut 2a which interacts with the outside handle of the door and an inner nut 2i which interacts with an inside handle of the door. The two nut parts, that is to say both the outer nut 2a and the inner nut 2i, are arranged on a common axis of rotation. Each of the two nut parts can be separately engaged and / or disengaged. When disengaged, the two nut parts 2a and 2i can be rotated freely. When engaged, the respective nut part is connected to the lock mechanism in such a way that when the associated door handle is actuated, the locking elements, i.e. the lock bolt 1 and / or the tilt latch 3, are unlocked or drawn into the lock housing. The handle sensor 5 is arranged above the lock nut 2. The pusher sensor 5 has two microswitches 5a and 5i arranged in alignment and at a distance from one another. The microswitch 5a interacts with the outer nut part 2a as an outer nut sensor 5a. The microswitch 5i interacts with the inner nut part 2i as an inner nut sensor 5i.

A shift fork 51 is arranged between the lock nut 2 and the pusher sensor 5. The shift fork 51 has two resilient shift tongues 51i and 51a. The two switching tongues are made of spring steel. The switching tongue 51i interacts with the inner nut 2i and the inner nut sensor 5i. The switching tongue 51a interacts with the outer nut 2a and the outer nut sensor 5a. The switching tongues 51i and 51a are connected to one another at one end. At their opposite end, both switching tongues 51i and 51a project freely between the lock nut and handle sensor. The switching tongue 51 is formed in one piece and can be produced, for example, as a stamped part made of spring steel. The Switch tongues 51i and 51a of the shift fork 51 translate the rotational path of the respective nut part 2a or 2i in such a way that actuation of the corresponding microswitch 5a or 51 is ensured regardless of the angle of rotation of the lock nut 2. As a result, on the one hand, an early response of the nut sensor 5 can be achieved and, on the other hand, continuous actuation of the microswitch can be maintained over the entire rotation range of the lock nut.

In the Fig. 7 a detailed representation in the area of the bolt sensor 85 is shown. The bolt sensor is designed as a microswitch, which is mounted in the lock case 81. The slide plate 84 runs at a distance above or parallel to the microswitch 85. The slide plate 84 has a switching flag 86 for actuating the microswitch 85. The switching flag 86 protrudes approximately perpendicularly from the surface of the slide plate 84 and actuates the microswitch 85. In order to avoid jamming, the switching flag 86 is designed as a spiral spring which swings out when subjected to a lateral load and thus jamming of the slide plate 84 and thus Microswitch 85 prevented.
