Summary of the invention

The invention is based on the object of developing a generic glass door lock and a generic locking device in an advantageous manner in order to integrate it wirelessly into a smart home system or into a building automation device.

The object is achieved by the invention specified in the claims. First and foremost, it is proposed that a simple energy converter, which is able to convert mechanical power into electrical power, is arranged in the lock case or in the strike plate. The energy converter can be a piezo element or a coil arrangement, a voltage being generated in a coil of the coil arrangement by moving a magnet past it. This voltage can be rectified and temporarily stored in a capacitor. With the energy / voltage temporarily stored in the capacitor, for example, an electrical circuit can be supplied with energy, which automatically sends a clear identification signal when the energy is supplied, with a frequency in the megahertz range as the transmission frequency is preferred. An unambiguous identification signal is understood to be a bit sequence or a byte sequence which is unambiguous at least on a system level, but preferably worldwide. The unique identification signal is preferably sent with a radio module which has an antenna and is also housed in the lock case, the antenna being arranged at the rear of an opening in the lock case in such a way that the antenna is not shielded by the metal of the lock case. In a preferred variant of the invention, a button is used as the energy converter which, at an operating voltage of 2 volts, delivers electrical energy of 120 to 200 μJ when actuated from mechanical power supplied over a short period of time. The electrical energy is preferably obtained from a mechanical movement that a mechanical element performs when the lock is actuated. For example, the energy converter can interact with a trap, a latch tail, a nut, a bolt slide or a bolt. The energy converter can be arranged at the rear of a trap tail, the movement of the trap tail moving a magnet when the trap is withdrawn, which magnet indicates a voltage in a coil. The magnet can also be moved past a coil when turning a nut. Similarly, a magnet can be coupled to the bolt slide or the bolt to induce a voltage in a coil. An energy converter can be arranged in a strike plate in a latch inlet opening and / or in a bolt inlet opening, the magnet of which is moved when the bolt head is inserted into the bolt inlet opening and / or when the latch head is inserted into the latch inlet opening. A commercially available energy converter can be used, in which the displacement of a pushbutton causes the displacement of a magnet in the area of action of a coil. In a preferred development of the invention, the lock has a sensor for determining a locking state. However, the radio module is set up in such a way that, together with the unique identification signal, a signal relating to the locking status is also transmitted. For example, can the sensor interact with a probe arm which protrudes from the faceplate of the lock and which is brought into a retracted position when a door equipped with the lock is closed. The sensor can output the values one or zero, which are transmitted together with the unique identification signal, so that the door's closed status can be transmitted wirelessly. In a strike plate according to the invention, two radio modules can be provided, each of which interacts with an energy converter, which are acted upon mechanically when the latch is retracted into the latch inlet opening or which are actuated mechanically when the bolt is retracted. The two radio modules send different unique identification signals from each other, so that the identification signal can be used to determine whether only the latch has snapped into the strike plate or whether a bolt has also been locked. As an alternative to this, however, two sensors can also be used which deliver sensor signals if, for example, mechanical energy is supplied to an energy converter by snapping the trap into the trap inlet opening. Together with the unique identification signal, sensor signals are then transmitted that provide information about whether the bolt is also locked in addition to the trap. It is considered particularly advantageous if the radio module emits the identification signal, if necessary together with sensor data, every time energy is applied to the energy converter. The radio signal containing an identification signal is preferably sent with each application of energy.

In a preferred embodiment of the invention, the lock is part of a building automation system or part of a smart home, which is understood to mean a system that has at least one central unit that interacts with at least one receiving device that can also perform a transmission function. The transceiver is able to communicate with a large number of radio modules or to receive wirelessly transmitted data from different radio modules, the range of the radio modules preferably being a maximum of 20 meters. The radio modules, which can also be connected to sensors or actuators, are able to perform various functions in a building, for example to switch power sources on or off, for example to switch lighting on or off, lower or raise a blind, a To change room temperature etc. According to the invention, the lock or strike plate described above is part of such a system, the system being set up so that the data supplied by the radio module of the lock or the radio module of the strike plate are fed to a central unit. In the simplest case, the data can only be the unambiguous identification signal, so that the central unit can log when a certain door has been operated, opened or closed. If sensor data are transmitted in addition to the unique identification signal, the central unit receives additional functional data about the locking status of the lap.

It is provided that the locking device has a lock case which has the standard dimensions of a glass door lock. Such a lock can be hung on a broad side of a door leaf made of glass. The door leaf has at least one circular opening through which a lock cylinder or the axis of a handle can be inserted. The at least one opening has a circular cross section. Two such openings are preferably located one behind the other in a horizontal direction, with the axis of the handle protruding through one of the openings of the lock cylinder and through the other of the openings. The glass door lock according to the invention has an elongated shape, the longer edge of the lock housing extending in a horizontal direction in the assembled state and a latch or a bolt can protrude from a narrow side of the shorter edge of the lock housing. It is intended that the housing of the Lock made of metal, wherein the housing can have a housing wall and a housing base. The housing base can be made of metal, but also of a non-metal. It can be provided that an end section of the housing directed away from the narrow side having the trap, which end section can have a straight or rounded edge, is made of a dielectric material, for example a plastic, so that an antenna of a radio module arranged there generated electromagnetic alternating field can be radiated through the housing. The housing can have an inner housing which is covered by a cover shell. In a preferred embodiment of the invention, both the inner housing and the cover shell can be made of metal. The housing base is mounted on a support mat made of rubber or soft plastic, which is arranged between the housing and the surface of the door leaf. In a variant of the invention it is provided that the rear wall of the housing has a window. The alternating electromagnetic field radiated by the antenna can be radiated through this window into the door leaf, which is preferably a glass door leaf. It can be provided that the window is filled with a dielectric filler piece. The window can be arranged on the edge of the housing base made of metal and directly adjoin a housing wall made of metal. In a variant of the invention, it is proposed that the antenna and / or a radio module having an antenna be arranged on a faceplate of the lock case. The radiation direction of the antenna is then preferably the surface normal of the faceplate. When the door is closed, the faceplate made of metal lies opposite a strike plate which is attached to the door frame. A free space (rebate gap) extends between the strike plate and the faceplate forming the front of the lock case, which is inserted into an insertion opening in the door leaf, and the strike plate. The antenna radiates its electromagnetic alternating field into this free space, which is radiated through the non-metallic narrow sides of the free space into the area outside the door.

The invention also relates to a glass door with locking devices arranged on both sides of the glass door leaf, at least one of which has a radio module which has an antenna that sends an alternating electromagnetic field into the gap between the two locking devices filled by the glass door leaf.

Description of the embodiments

That in the Fig. 4 The building automation system shown has a central unit 20, which can be a microcomputer or the like. The central unit is connected to one or more transmitting / receiving devices 21, 21 'via a line or also wirelessly. A large number of radio modules 12, 12 ', 22, 22' are provided, which are arranged at different locations in a building and which, upon wireless request from the central unit 20 or automatically, receive information via the transceiver 21, 21 ' the central unit 20 transmitted. The radio modules 22, 22 'can be light switches or light sensors or thermostats or temperature sensors, which each transmit a unique identification signal (UID) to the transceiver device 21'. The transmitting / receiving device 21 'can transmit data (B) to the radio module (22). The radio module (22 ′) can also transmit data (A) to the transmitting / receiving device 21.

The invention relates to a self-sufficient door lock 1 or a self-sufficient strike plate 13, which is in the Fig. 4 system shown can be integrated. For this purpose, the lock 1 or the strike plate 13 has a radio module 12, 12 'which is able to use the same protocol with which the central unit 20 communicates with the radio modules 22, 22' via the transceiver 21 ' the transmitting / receiving device 21 to communicate with the central unit 20.

Immediately after the application of energy, the radio module 12 sends an at least system-unique, but preferably globally unique, identification signal UID to the transmitting / receiving device 21, which transmits the signal to the central unit 20. The radio module labeled 12 ′ can additionally be able to transmit sensor data S1 via the transceiver 21 to the central unit 20 together with the unique identification signal UID.

One in the Figures 1 and 2 The lock shown as an example has a lock case 2 made of steel, in which there is a latch 7 having a latch head, the latch tail 8 of which protrudes into the lock case 2. In addition, a button 9 is provided which protrudes over the faceplate 3 when the door is open and which runs against a counter-locking part 13 when a door equipped with the lock 1 is closed and is brought into a retracted position.

In the lock housing there is also a nut 5 which can be rotated by a handle and which engages the latch tail 8 with a nut arm 6. If the latch 7 is withdrawn, a latch spring ensures that the latch 7 is extended again after the trigger has been actuated.

In addition, a bolt slide 4 is provided in the lock case, which cooperates with a bolt, not shown. If the bolt slide 4 is pre-locked with the aid of a key or a lock cylinder, the bolt emerges from the faceplate 3.

In the in the Figures 1 and 2 The locks shown are energy converters 10 which are able to convert mechanical energy into electrical energy. This can be done, for example, with a Fig. 5 circuit shown schematically take place.

The Indian Fig. 5 The energy converter 10 shown has a magnet 18 which can be moved by a movable mechanical part of the lock 1 with respect to an armature 16 on which a coil 17 is wound. The voltage indicated during the movement of the magnet 18 in the coil 17 is rectified with a rectifier and connected as energy in a capacitor. The energies here are in the range between 100 and 200 µJ. A circuit 19 can operate the radio module so that when it is energized it sends at least the unique identification signal UID or also a data record S1.

The radio module 12, which interacts with the energy converter 10, is arranged in the lock in such a way that an antenna of the radio module 12 is arranged at the rear of a lock opening.

The one in the Fig. 1 The illustrated embodiment, the energy converter 10 lies in the movement path of a bolt slide 4. It could, however, also lie in the movement path of a bolt 7 displaceable by the bolt slide 4. If the bolt slide 4 is displaced, a magnet, not shown, of the energy converter 10 is displaced so that for a few milliseconds an electrical power is generated, which is temporarily stored as energy in a capacitor. The radio module is operated with this energy.

The one in the Fig. 2 The illustrated embodiment, the energy converter 10 sits at the rear of the trap tail 8, so that a trap retraction supplies electrical energy and causes the radio module 12 to send the unique identification signal UID.

In both Figures 1 and 2 sensors 11 are also shown, which interact with the probe arm 9. A correspondingly modified radio module 12 is then not only able to emit the unique identification signal UID, but also to transmit sensor data S1 to the transmitting / receiving device 21, these data providing information on whether the probe arm 9 is extended or retracted.

The one in the Fig. 3 In the illustrated embodiment, an energy converter 10 is arranged in the area of a latch inlet opening 14 of a strike plate 13 or in the area of a bolt inlet opening 15 of the strike plate 13. Here, too, the electrical energy obtained via mechanical power is used to send a unique identification signal with the aid of the radio module 12.

For this purpose, the trap 7 entering the trap inlet opening 14 acts on a button, a plunger or the like with which, for example, a magnet is moved past a coil. If a bolt enters the bolt inlet opening 15, the bolt can displace a magnet of the energy converter 10 there in an equivalent manner.

Instead of inductively operating energy converters 10, however, piezoelectrically operating energy converters can also be used.

According to the invention, the lock described above can be used with a strike plate in such a way that an electromagnetic alternating field emitted by the radio module 12 or an antenna assigned to the radio module 12 is emitted into the gap between the strike plate and the faceplate of the lock. The radio module 12 or the antenna can be assigned either to the lock or to the strike plate.

The Figures 6 to 11 show a variant of the invention in which the lock 1 has a lock case 2 which can be arranged on a door leaf 23 made of glass. The lock housing has an elongated shape with two parallel long edges extending in a horizontal direction in the assembled state and two edges extending transversely thereto, one of which is adjacent to a front narrow side from which a latch 7 can emerge. The other narrow side can run straight or - as shown in the exemplary embodiment - rounded. This marginal edge runs along a rear section of the lock case 2.

In the lock case 2 there is an insertion opening 37 for a lock cylinder and a rotatably mounted handle shaft 38 which supports a handle 28. The handle axis 38 extends through an opening 34 of the door leaf 23. The lock cylinder insertion opening 37 is located at the level of an opening 24 of the door leaf 23. The two openings 24, 34 have a circular cross-section and a standard size and a standard position on the door leaf 23. They are a standardized distance apart spaced from the edge of the door leaf 23 and lie next to one another in the horizontal direction.

The lock case 2 has a housing base 23 made of metal, the edge of which is adjacent to a housing wall 31, which is also made of metal. The housing wall 31 can be connected to a housing cover which extends parallel to the housing base 23. An inner housing designed in this way, which stores the lock mechanism (not shown in the drawings), is covered by a cover shell 29.

The lock housing is mounted on the door leaf 32 with a cover mat 30 made of rubber or the like in between. On the opposite side of the door leaf 23 there is a fitting 33 which supports the handle axis 38.

In the lock housing there is a radio module 22 to which an antenna 25 is connected. The antenna 25 runs along the edge of the housing base 32. The antenna 25 runs in particular along a window 35 of the housing base 32, which window 35 extends on the edge of the housing base 32. The alternating electromagnetic field generated by the antenna 25 can pass through this window 35 to the outside. The window 35 faces the glass door leaf 23, so that the electromagnetic alternating field is radiated into the glass door leaf 23, through which it passes into the environment.

The one in the Fig. 9 The illustrated embodiment, the window 35 is filled with a filler 36 made of plastic. The in Fig. 8 The illustrated embodiment, the window 35 is open.

The window 35 can be an elongated recess in the housing base 32, which can be made entirely of metal. The window 35 can directly adjoin a housing wall 31. However, it can also adjoin an inner shell of the housing arranged within the housing wall 31. The window 35 can have an elongated shape and extend along the longitudinal edge of the housing base 32. The antenna 25 can have an elongated shape and extend parallel to the window 35. The distance between the antenna 25 and the window 35 can be less than the width of the window 35, that is to say the distance between two longitudinal edges of the window 35 from one another. The antenna 25 can, however, also lie in the window 35. The antenna 25 is preferably formed from a wire or a conductor track of a circuit board, the circuit board extending in the immediate vicinity of the housing base 32. The electromagnetic alternating field generated by the antenna 25 passes through the window 35 and the possibly existing support mat 30 and into the glass door leaf 23. The electromagnetic alternating field propagates through the glass door leaf 23 to a receiving device 21 arranged remotely from the door.

The Figures 10 and 11 show an energy converter 10 with an armature 16 surrounded by a coil (not shown) and a magnet 18 that can be displaced transversely to the direction in which the armature 16 extends. A first spring element 41 is provided, which can be actuated by a cam 40 of a slide 39. The slide 39 can be moved by an arm 6 of a follower 5 in the horizontal direction. The cam 40 slides over the first spring element 41, which interacts with a second spring element 42 in such a way that the displacement of the slide 39 generates a movement of the magnet 18. This movement induces a voltage and a current in the coil (not shown). The radio module 22 is energized with the electrical power generated in this way.

While the one in the Fig. 10 illustrated embodiment, the cam 40 interacts directly with the first spring element 41, the cam 40 acts in the in the Fig. 11 The illustrated embodiment together with a transmission lever 43 which acts on the first spring element 41.

The Figures 12 and 13 show a mortise lock inserted into a door. The mortise lock has a lock case 2 which is inserted into a pocket of the door leaf 23. At the front of the lock case 2 there extends a faceplate 3 made of metal, through which a latch 7 and / or a bolt 4 can extend. The trap 7 enters a trap inlet opening 14 of a strike plate 13 which is attached to the door frame. The bolt 4 enters a bolt inlet opening 15 of the strike plate 13.

A radio module 22 with an antenna 25 is inserted in an opening of the faceplate 3, which extends between latch 7 and bolt 4. The opening points in the direction of a rebate gap 27 which, when the door is closed, extends between the faceplate 3 and the striker plate 13. The electromagnetic alternating field emitted by the antenna 25 is radiated into the rebate gap 27 and can escape through the frame 26 or the door leaf 23 from the two narrow sides of the rebate gap 27, which are neither covered by the metal strike plate 13 nor the metal faceplate 3.
