Summary of the invention

The invention has for its object to provide a cabinet door lock, which is interchangeable with a manually operated cabinet door lock and has improved functionality.

The object is achieved by the invention specified in the claims, wherein the dependent claims represent not only advantageous developments of the claimed in the main claim cabinet door lock, but are also independent developments of the prior art.

In its entirety, the cabinet door lock has the structural and functional features listed below, which are individually but also in combination of inventive importance. The cabinet door lock has a housing. The housing can be fastened to a cabinet door on the inside facing a cabinet interior. In particular, it can be exchanged for a cabinet lock already present there, which does not have the technically further developing features of the invention. The housing includes a motor that can be driven by an electronic circuit, or a handle that can be coupled with a latch drive. The electronic circuit cooperates with a code input device. About the code input device, an opening code can be entered. This can be done via a keyboard. The code input can also be done by keeping close to a transponder. For this purpose, the code input device has a communication device which communicates wirelessly with the transponder. A wireless wake-up signal is sent to the transponder so that the transponder transmits its individual identifier to the code input device. The code input device can permanently or intermittently generate a test signal which builds up an electromagnetic detector field to check whether a Transponder is located directly near the cabinet door lock. This signal is generated with very low power, so it has no remote effect. Only when the presence of a transponder in the immediate vicinity of the code input device is detected, a more powerful wake-up signal is generated, which causes the transponder to send its identifier. The code input device or the electronic circuit have a closing authorization check device with which it is checked whether the opening code received via the keyboard or the transponder reading device has a locking authorization. This check is made on the basis of an activation of the electronic circuit, which takes place either by the PIN input or the reading of the identifier of a transponder. If the locking authorization of the opening code is determined, ie in the event of an authorized closing of the electronic circuit, the bolt can be displaced back and forth between two locking positions with an actuating unit. For this purpose, it may be provided that the motor is put into operation in order to shift the bolt, which is displaceable back and forth between two locking positions, into the respective other locking position. But it is also envisaged that a clutch that couples an actuating handle with a latch drive from a disengaged position to a coupled position in which the actuator displaces the latch. The bolt is thus placed either in an open position in which the cabinet door can be opened, or in a locking position in which the cabinet door can not be opened. A transceiver device is provided, which is functionally separated from the optional transponder reader. This, cooperating with the electronic circuit transmitting-receiving device is used for wireless data transmission of at least closed state data to a central processing unit. It is envisaged that in one and in particular each activation of the electronic circuit lock status data are transmitted to the central unit. The lock state data includes at least the lock state of the lock before and after the code entry and / or the lock entered code, ie the PIN or the individual transponder identification. With the central unit, a plurality of cabinet door locks can thus be managed an arrangement including a plurality of cabinets. The cabinet door lock management occurs as a result of wireless remote data transmission without the need for lines, especially bus lines. The housing has a battery holder. The battery holder can be arranged in the same housing, which also includes the latch. The housing may also be formed of a plurality of spatially separate individual housings, wherein the battery may be arranged in a separate housing from the bolt. The battery is used in particular for supplying power to the motor or the clutch, the electronic circuit, the code input device and the transceiver. Preferably, all electrical or electronic units of the cabinet door lock are battery operated, so that the cabinet door lock does not require a cable connection to an external power supply. It is thus a self-sufficient lock, which may have a long operating time, since it is provided that the transceiver predominantly assumes its idle state. It is provided that the transceiver sends a sign of life to the central unit only after a predetermined time interval and otherwise transmits closing status data to the central unit only when the electronic circuit is activated. The transceiver is only ready to receive if it has previously been activated or has sent the cyclic sign of life, it being sufficient if the transceiver sends once a daily sign of life in this regard. This minimizes energy consumption. The electronic circuit includes a clock that provides a clock upon which a low power transponder detection signal is established to detect the presence of a transponder and the sign of life is sent to the central unit. Functions with a higher energy consumption are only made individually after an activation. Instead of a wireless detection of the approach of a transponder, however, it is also possible to provide a switch which, for example, must be actuated by installation of the transponder in order to start the data communication with the transponder. The code input device can be designed as a modular communication module. This communication module can be arranged in a receiving compartment of the housing. The communication module can thus be located on the inside of the cabinet. In this arrangement, the electronic circuit can only be activated by the approach of a transponder. The wireless communication with the transponder then takes place through the cabinet door, in particular made of wood. The communication module can also be mounted on the outside of the door. It is then connected via a cable to the electronic circuit. Preferably, a plug attached to the end of the cable plugged into a plug-in socket of the electronic circuit. The communication module can be used as a door handle. The cabinet door lock can be used on left hinged as well as on right hinged closet door wings. For this purpose, the cabinet door lock has a bolt, which is preferably longer than the width of the lock and the means of the motor in the width direction can be moved back and forth, so that in each case one end of the bolt protrudes beyond the housing. In a first operating position, a first end of the bolt projects beyond a first side of the housing. In a second operative position of the latch, a second end of the latch, which is opposite the first end, projects beyond a second side of the housing opposite the first side of the housing. The housing has Anschrauböffnungen, which are arranged according to a hole pattern, which is a lock, as it is known from the above DE 19 832 516 A1 or the DE 10 2007 052 583 A1 is known owns. The cabinet door lock can thus be easily replaced with a conventional cabinet door lock. No additional cable connections are needed for either power or data communication. Nevertheless, the lock can be managed in a simpler way and can preferably be a variety of identically designed cabinet door locks a cabinet arrangement, for example. Manage in a swimming pool. It is thus possible to respond to disturbances. Thus, it is possible that the cabinet door lock has one or more sensors or sensor elements with which it can be determined whether the lock has an electronic, mechanical or other fault. The electronic circuit can be set up so that it sends a status message to the central unit even if a fault is detected. The cabinet door lock then sends an alarm or fault signal to the central unit. It is further provided that with the sensors or sensor elements vandalism or attempted breakthrough can be detected, so that a signal is transmitted to the central unit via the transceiver. With this alarm signal, a silent or noisy alarm can be triggered. It is also possible to respond to the loss of a PIN or a transponder by the cabinet door lock receives an opening command at any activation by any key combination or by any transponder from the central unit, which causes, for example, that the engine Pull back the latch. It is also envisaged that the bolt can not be closed or closed manually via a motor.

Description of the embodiments

The cabinet door lock S of the invention has an example made of plastic housing 1, which is mounted on the inside of a cabinet facing inside a cabinet door 10 of a cabinet. The attachment of the housing 1 to the cabinet door 10 by means of screws 15 which can be screwed through Anschrauböffnungen 14 of the housing 1 into the door leaf. The Anschrauböffnungen 14 are located on the vertices of a rectangle.

Within the housing 1 there is a bolt 2. In the embodiment, the bolt 2 has a length such that it can be brought into a second operating position by actuating an actuating unit 4 from a first operating position, in which a bolt head protrudes on the left side of the lock. in which a bolt head protrudes from the right side of the lock. The length of the bolt can be greater than the distance between two opposite marginal edges of the housing. In the FIG. 1 the left end of the bolt 2 is shown in its locking position. The right end of the bolt 2 assumes an open position. An actuating unit, which may be a motor 4 or a manually rotatable handle, engages the latch 2 in such a way that an actuation of the actuating unit releases the latch from the in FIG. 1 shown in the first position in the FIG. 2 shown second position and can shift back to the first operating position. For this purpose, for example, an eccentric pin 3 engage in a transverse slot of the bolt 2.

The housing 1 has a battery receptacle 6. In the battery receptacle 6, one or more, preferably three batteries 7 may be arranged. The batteries are used to power the cabinet door lock S. Preferably, all electrical and electronic consumers of the cabinet door lock S are powered by the batteries 7.

Within the housing is an electronic circuit 5. The electronic circuit 5 interacts with the electric motor 4, an access control device 16, a code input device 11 and a radio module 8 together. The radio module 8 includes a transmitting / receiving device to transmit data, in particular closed state data to a central processing unit Z. The code input device 11 may be a communication module, which can find in a compartment 9 of the housing 1 recording. Over a Cable connection 17, the communication module 11 is connected to the electronic circuit 5. The access control device 16 may be a physical part of the electronic circuit. This can be a microcontroller arrangement which is able to check an opening code for locking authorization.

The FIG. 4 shows a first installation variant of the cabinet door lock S invention S. The housing 1 is located on the inside of a cabinet door. The communication module 11 is located on the outside of the cabinet door and can be used as a handle. Via the cable 17, which passes through an opening of the door leaf 10, the communication module 11 is connected to the electronic circuit 5.

In a second installation variant, the FIG. 6 shows, the communication module 11 is located in a receiving pocket 9, which is located on the Anschraubseite of the housing.

The communication module has a keyboard consisting of a plurality of keys 12 to key in an opening code. It also has an antenna arrangement 13, with which a data transmission communication with an RFID device, a transponder can be performed to read the recognition of an approach of a transponder to the communication module 11, the digital identifier of the transponder. The access control device 16 then checks whether the entered PIN or the transponder identification has a locking authorization. The typing in of a code or the recognition of the approach of a transponder leads to an activation of the electronic circuit 5, so that a data record is sent to the central unit Z via the radio module 8. Subsequently, the transceiver of the radio module 8 has for a short time a reception standby and is capable of receiving control data or the like from the CPU Z. For example. It can be provided that the transceiver 8 transmits the PIN or the transponder identification to the central unit Z and the latter sends the transceiver 8 a closing or an opening command, so that the locking device is only activated after the locking authorization has been checked by the central unit. or can be deduced. But it is also envisaged that the cabinet lock S works independently and checks the locking authorization itself.

The reference numeral 18 symbolizes sensors or sensor elements with which certain operating states of the cabinet lock or cabinet can be detected. With these sensors or sensor elements 18, for example, the proper functioning of the cabinet door lock S can be checked. It is also possible to detect with these sensors or sensor elements 18, if manipulation attempts are made on the cabinet door lock, so that in such a case, the transceiver 8 transmits an alarm signal to the central device Z. It can thus be responded to vandalism and interference. Furthermore, it is possible to remotely open or close the cabinet door lock, for example in order to react to the loss of a transponder key or a PIN. In this case, an activation of the electronic circuit, by inputting any desired PIN or by approximating any transponder to the communication module 11, is sufficient to displace the latch 2.

The FIG. 8 shows a block diagram of an arrangement as it is, for example, in a swimming pool. Often there are several hundred cabinets of the same design, each equipped with the same cupboard door locks S. Each of the cabinet door locks S communicates with the central unit Z, so that with a central unit Z via a wireless Communication connection can manage a variety of self-sufficient cabinet locks S, without the power supply lines must lead to the individual cabinet door locks or between cabinet door lock S and central unit Z a data transmission line must be present.

The cabinet door lock S invention operates with a minimum of energy. The electronic circuit 5 can have a clock which causes the communication module 11 to produce at low intervals a transponder detection signal which builds up a transponder detection field only in the area immediately around the communication module 11. Only when a transponder is detected within the transponder detection field, the electronic circuit for data communication with the transponder is activated or sends the transceiver 8 Schließzustandsdaten to the central unit Z and goes for a predetermined time in a receive mode in which it is capable To receive data from the central unit Z. Otherwise, the transceiver is in an idle state. The batteries thus have a very long service life.
