Description

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

A conventional, electrically operable pusher lock, which has a panic function B, is located in the locked position (initial position) as follows: bolt extended, on panic opposite side pusher decoupled, panic side pusher coupled, trap extended, resp. Drop attacks rigid. If during the inspection of the door on the panic opposite side, now the pusher pressed before an electrical opening impulse, for example via an access control device, takes place, the door can not be opened while still pressing the pusher. To open the door, the pusher must first be released, resp. be pulled up to couple by pressing the pusher again the pusher. Consequently In this case, a two-handed movement is absolutely necessary for the inspection of the door.

Such pusher locks are well known in the market. However, these require when operating the pusher before the triggering of the electrical opening pulse, always a new pusher movement (two-handed movement) to open the door. This previously necessary in this constellation (opening signal when pressed trigger) operating mode (two-handed movement) corresponds to the current state of the art.

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

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

According to the invention, the pusher sensor has an outer sensor cooperating with the outer nut, and the control device is designed so that it initially spends the lock bolt and / or the latch after receiving an opening pulse in the closed position and uncoupled outer nut via the drive motor and then the drive motor for moving the lock bolt and / or the lock latch activates in the open position, if after reaching the day position of the outdoor sensor detects an operation of the outer handle, or the outdoor sensor detects that a Operation of the outside pusher persists. Thus, an opening of the lock can be made, even if the outer handle has already been pressed before the opening pulse, for example, was generated via a transponder. Thus, a one-hand operation is possible, so to speak, without the need to re-release and follow the exterior door handle.

It is also provided that when uncoupled Außenennuss an opening of the locked lock takes place by first a first opening pulse is generated in a first step on the basis of a correct access authorization to spend the lock bolt and / or the latch via the drive motor from the closed position in the day position and that in a second step upon actuation of the outer handle on the trigger sensor, a second opening pulse is generated to spend the lock latch and / or the case motor in the open position. Thus, it is possible to allow access to a building from the outside for an authorized person with access to a building by requiring only a single push of the outside button after reading in or entering a correct access authorization in order to completely unlock the access.

In particular, it may be provided that in the second step, the second opening pulse is generated or generated via an outer sensor of the pusher sensor, which cooperates with the outer nut for detecting a pusher movement. It is advantageous if in the second step, the second opening pulse is generated regardless of whether the outer handle was pressed before reaching the day position or is pressed only after reaching the day position.

Further, 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 window sash is driven into an open position.

It can be provided that the invention simplified access to panic locks with panic function B can be realized. With panic function B, the lock locks the access automatically when closing the sash. In this locked position, the door can always be opened from within the secured room or building via the internal 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 transmits an access code that is read and verified by a reading device, is in the panic function B of the Outside door handle located on the outside engaged, so that the passage is also possible from the outside.

A problem arises when the exterior door handle is pressed before the correct access authorization is entered. Then the outer nut is already turned by the outer door handle and can not be neatly engaged as a rule. The present invention circumvents this problem by interrogating after entering or reading a correct access code or signal sensor signal associated with the Außenennuss or the exterior door handle and the lock is opened by motor when operating the outer handle. It is, so to speak, a combination of the pusher lock function with a motorized lock.

The device according to the invention and the method according to the invention can also be used with a panic function E. With a panic function E, the access is also automatically locked by a lock when the door is closed. From inside, the locked door can always be opened via a door handle. In case of a panic it is ensured that the secured building or the secured room can be left. The external pusher is usually disconnected permanently in the panic function E. In the case of conventional locks with panic function E, access from the outside for an authorized person is possible only with one key. The present invention allows for a panic E-function in addition to the access with a key and the comfortable conquest of access with a one-hand function by no key must be rotated, but it is sufficient after reading a correct access code, for example via a transponder or a RFID chip or entering a numerical code to operate the exterior door handle. This makes it possible to realize a panic function E as a barrier-free passage.

An opening pulse can be understood, for example, as a control command of a bus system or a higher-level control device. It may also be understood as meaning a pulse generated by a sensor or switch contact or a contact signal of a switch, preferably an N / O (normally open) or N / C (normally closed) switch.

It can be provided that the opening pulse is generated via a reading and / or input device by reading in and / or verifying an access code by the reading and / or input device. For example, the reading and / or input device can read in a code of a transponder or an RFID tag wirelessly, whereby a person authorized to enter the Transponder or the RFID tag for reading in front of the reading and / or input device holds. The reading and / or input device can also be arranged at a central point of a building, for example at a gatekeeper and send an opening pulse to the lock or to the control device of the lock on the basis of a release of the access 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.

Under open position is understood a retracted into the lock housing position of the lock bolt and the lock latch. In the open position, the door can be freely negotiated and the door can be opened. When using a lockable dump or cross latch, the blocking of the trap is released in the open position.

In the figures, an embodiment of the invention is shown, in which in each case the same components are provided with the same reference characters. The Fig. 1 shows a securing device 9 with a door 91 with a door hinges 92a, 92b on a door frame 91 r rotatably mounted door leaf 92. The door 92 has at its closing edge a mortise lock 8, which is actuated via a door handle 94. About the castle 8 can the Door leaves 92 are locked in the closed position to secure access. At the top of the door leaf 92, a door drive 95 is arranged to open or close the door driven by a motor. In the area of the door lock, a reading and / or input device 93 is arranged on a wall of the building in order, for example, to read in an access authorization wirelessly, for example via a transponder.

In the Figures 2-5 the mortise lock 8 is shown with removed lock cover. The mortise lock 8 has a lock case 81, in that locking elements, namely a two-speed locking lock bolt 1 and a lockable tilting trap 3, are arranged. In the lower part of the lock case a receptacle for a lock cylinder is arranged. 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 plate 82 in order to actuate the locking elements tilting 3 and long bars 1.

The mortise lock 8 is designed as a self-locking panic lock. It has a spring loaded on the unlocking of the castle. About a tax trap 31 and the dumping 3 a closing of the door is detected, wherein after moving the door in its closed position, the long bar 1 automatically excludes two-way, ie in the in Fig. 2 shown closed position is moved out of the lock housing. At the same time the Kippfalle 3 is locked, so in the in Fig. 2 shown closed position the lock 8 securely locks the door.

In the Fig. 3 the lock 8 is shown, wherein in the illustration of Fig. 3 the lock nut 2 or its outer nut part 2 a is actuated via a door outer handle, not shown. The locking elements 1 and 3 are in the illustration of FIG. 3 still in the closed position. That is, the bolt 1 is extended two-speed and the dumping box 3 is locked, that is rigidly connected.

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 upon entry of a correct access code via the reading and / or input device 93. As a result of the opening pulse, the control device 41 has the motor 83 driven so that it has moved over the slide plate 84, the bolt 1 in its day position, ie in the one-speed excluded position. The in the FIG. 4 illustrated day position includes the long bar in its partially excluded position, ie the long bar protrudes by about 5mm out of the lock housing. The Kippfalle 3 is still locked in the day position, ie rigidly connected.

In the Fig. 5 the open position of the lock 8 is shown. After reaching the in Fig. 4 Day position shown, the outside handle, not shown, is still operated. The lock nut 2 or its outer nut part 2a interacts with the control device 41 via the pusher sensor 5. By in the representation of Fig. 5 still continuously actuated external pusher is generated via the trigger sensor 5, a second opening pulse. Due to the second opening pulse, the control device 41 controls the electric drive motor 83 to fully open the lock 8. Then the latch 1 is completely retracted into the lock 8 and the dumping box 3 unlocked.

In the Fig. 6 an enlargement of detail in the area of the lock nut 2 with the pusher sensor 5 is shown. The lock nut 2 has an outer nut 2a interacting with the outer handle of the door and an inner nut 2i cooperating with an inner handle of the door. The two nut parts, ie both the outer nut 2a and the inner nut 2i, are arranged on a common axis of rotation. Each of the two nut parts is separately retractable and / or disengageable. In the disengaged state, the two nut parts 2a and 2i can be freely rotated. In the engaged state, the respective Nussteil is connected to the lock mechanism, that upon actuation of the associated door handle, the locking elements, ie the long bars 1 and / or the dumping trays 3, unlocked or fed into the lock housing. Above the lock nut 2, the pusher sensor 5 is arranged. The pusher sensor 5 has two aligned and spaced-apart microswitches 5a and 5i. The microswitch 5a cooperates with the outer nut part 2a as the outer nut sensor 5a. The microswitch 5i cooperates with the inner-nut part 2i as the inner-nut sensor 5i.

Between the lock nut 2 and the trigger sensor 5, a shift fork 51 is arranged. The shift fork 51 has two resilient switching tongues 51 i and 51 a. The two switching tongues are made of spring steel. The switching tongue 51 i cooperates with the inner nut 2 i and the Innennusssensor 5 i. The switching tongue 51a cooperates with the outer nut 2a and the outer nut sensor 5a. The switching tongues 51 i and 51 a are interconnected at one end. At their opposite end, both switching tongues 51 i and 51 a cantilever freely between the lock nut and the trigger sensor. The switching tongue 51 is integrally formed and can be made for example as a stamped part of a spring steel. The Shifters 51i and 51a of the shift fork 51 translate the rotational travel of the respective nut part 2a or 2i such that, independently of the angle of rotation of the lock nut 2, an actuation of the corresponding microswitch 5a or 51 is ensured. As a result, on the one hand, an early response of the nut sensor 5 can be achieved and, on the other hand, a continuous actuation of the microswitches over the entire rotational range of the lock nut can be maintained.

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 extends at a distance above or parallel to the microswitch 85. The slide plate 84 has a switching lug 86 for actuating the microswitch 85. The switching lug 86 protrudes approximately perpendicularly from the surface of the slide plate 84 and actuates the microswitch 85. In order to avoid jamming, the switching lug 86 is formed as a spiral spring which pivots at a lateral load and thus jamming of the slide plate 84 and thus the Microswitch 85 prevents.
