RECORD KEY CABINET

The invention relates to a key cabinet comprising an apparatus for preventing the unauthorized removal of keys and an apparatus for registering a key taker and the keys taken. Key cabinets are already known. which store keys that are not allowed to be taken out of the house or whose use is to be controlled for other reasons. In addition, key cabinets are known from which several keys can be removed at once.

The disadvantage of these key cabinets is that not every key taker - ·. time necessarily identified, leaving also an irrelevant person ..! may take possession of the key or keys without being able to trace this event or person. It is also a disadvantage that it has been possible to take several keys at once, because then one or 'some of them' may fall uncontrollably into the hands of unrelated persons.

. The key cabinet according to the invention, which is associated with a locking device and a recording device, is characterized in that it comprises locking barriers, indicators monitoring the status of the key latch and a recording device which, after receiving information from the detectors, the child locks all other keys so that only one of the keys predefined in the registration1 equipment can be removed from or returned to the cabinet per registration.

For various reasons, it has been stated that it is important to improve access control in real estate. The most important items in this case are information about passers-by and passers-by. The key cabinet according to the invention is able to register the persons who have taken the keys and also the time of collection and return of the keys. In this case, it is known exactly who has moved or who has had the opportunity to move around the property or other locked object. This substantially facilitates, for example, subsequent investigations, monitoring of working time or other similar activities.

The enclosed figures illustrate a key cabinet according to the invention. Figures 1 and 2 show two cross-sections of the key cabinet, showing its most essential parts and their mode of operation. Figure 3 shows in block diagram form the operating principle of the key cabinet and the possible connection of the cabinet to its environment.

A key cabinet according to the invention is constructed from a housing (I) j formed of several known components. » the associated lid part (2). There are one or more key sockets (3) under the cover (21) with associated keys (4). When the key (4) is turned, the bar (5) normally attached to the lock housing also turns. The bar (5) can also be straight or bent different from the picture. In the key cabinet according to the invention, the removal of the key (4) from the key housing (31) is prevented by selecting the key housing (3) so that the key (4) can only be removed from it in the second extreme position of the key (4) (= position-open1). The movement of the bogie (5) from the 'locked' position is prevented by bringing an obstacle (6) across the path of movement of the bogie (5) .In this construction it is realized by an electromagnetic solenoid (7), which device is already known. (61 movement can be realized in other ways as well. If necessary, the anti-movement effect of the barrier (6) bogie (5) can be enhanced by guiding the barrier (61) to the guide hole (8). tty registration of the key cabinet according to the invention in the apparatus (9). which performs the identification and registration functions mentioned in the claims. A description of the operation of the apparatus (9) is shown in Figure 3. The opening of the key cabinet cover (2) is prevented by a locking apparatus (10) implemented here with an electromagnetic solenoid associated with the associated apparatus (see Figure 2). The locking device (10) is electrically connected to the device (9), 3 37955

The violent handling of the key cabinet is investigated with detectors placed in places depending on the structure of the cabinet »eg Miki o-switches (11). one of which is shown in Figure 1. Violent handling causes a change in the state of the detector (11), which is detected by the equipment (9) and performs an alarm action. whose quality r l depends on the object of application.

The key cabinet according to the invention works as follows:

In the initial situation, the key cabinet has the key (s) (3) in place in the 'locked' position, whereby the movement of the bars (5) of the key housing (s) is prevented by means of an obstacle (s) (6). When a person wants to take the key (s) from the cabinet (4), he introduces himself to the hardware (9) that controls the key cabinet. This can be done in a number of known ways, e.g. by assigning a personal, secret identification number to the hardware (9) by means of a previously known code keypad. The equipment (9) compares the received ID with the IDs whose holders have the right to remove the keys from the key cabinet (4). Such identifiers are pre-programmed in the memory of the hardware (9), which is also already known. If the received code has the right to remove the key or keys (4) from the cabinet, the equipment (9) will provide a locking. : an opening command for the hardware (10), allowing the person to: open the key cabinet door. At the same time, the device (9) releases the bogie (5) • by moving the obstacle (6) off the track by means of the solenoid (7). The bars (5) are only released for the keys (4) that the person is entitled to take according to the equipment (9). When a person turns over one of the keys allowed to him (4), all the others are locked, even if he has the right to more than one key (4). In particular, by programming the hardware (9) or otherwise, the matter can be arranged differently. The apparatus (9) comprises turning the key ':: (4) out of the' locked 'position in the same way as removing the key (4) L from the key cabinet. because the person then has the opportunity L. to remove the key from the cabinet. The removal of the key (4) is registered in the hardware (9).

Claims (6)

1. Key cabinet for a plurality of keys, to which the cabinet joins a reading device and a recording device, characterized in that the cabinet comprises several reading latches (6), the key rule's observing detectors and a recording device (9) which, if the detectors indicate that someone offset of the key rules from its 'open' or 'read' mode, reads all other keys so that only one of the keys in a predetermined group of keys can be removed from the cabinet or returned in it during a registration . 2. Key cabinet according to claim 1, characterized in that the recording device, which consists of, for example, an internal recording device (9) together with an external identification device, identifies the person who is entitled to use the keys on the basis of e.g. a personal identification number and allows the persons entered in the register to use the cabinet only during the times previously entered in the recording device (9) or a computer connected to this memory. The key cabinet according to claim 2, characterized in that the withdrawal and return of the key are recorded together with the key. . married about the time of registration. Key cabinet according to claim 3, characterized in that the personal identification number of the person who removes the key is stored in the internal recording device (9) or the external computer - | memory. 5. A key cabinet according to claim 4, characterized in that keys can be stored and removed from there by several different manufacturers, and a serial change of the keys can be carried out without touching the electrical design details. 6. A key cabinet according to claim 4, characterized in that if it is treated with vigor such that the condition of the detector (11) is changed, it triggers a predetermined alarm function in the recording, (9).
