EP3032004B1 - Locking system for a door or a window and method for making a locking system - Google Patents

Description

The invention relates to a locking system for a door or a window, with a wing side arranged lock, which has an electrically controllable locking function and a receiving unit for receiving control signals, and with a frame side arranged strike plate, which cooperates with a lock-side locking element.

Such a locking system is known for example in the form of a self-locking panic lock and is offered by the company BKS, Velbert, Germany, under the name "BKS radio battery lock 2170/2171".

A non-generic locking system is from the EP 1 832 700 B1 known. This system comprises a frame-side arranged receiving unit for receiving control signals for controlling an actuator arranged on the frame side, which transfers a locking element of the lock from a locked state into the lock case into an unlocked state.

From the EP 1 229 192 a door locking system with the features of the preamble of claim 1 is known. From the DE 36 12 761 is a device for the electrical power supply of door mounted power consumption devices known.

Proceeding from this, the present invention seeks to provide a simple as possible locking system.

This object is achieved according to the invention in a locking system with the features of the preamble of the claim by the characterizing features of claim 1.

The locking system according to the invention makes it possible to use an assembly of transmitter module and strike plate. This simplifies the arrangement of the transmitter module compared to a conventional, spatially distant from the strike plate arrangement. The arrangement of the transmitter module on the strike plate and / or in the region of the back of the strike plate makes it possible to use a frame-side anyway usually existing space. Furthermore, the distance for a wireless communication between the receiving unit and the transmitting module is reduced to a minimum, for example to a distance with a maximum length of 15 cm. This allows operation with only small transmission powers, regardless of whether the wireless communication via radio, WLAN, Bluetooth, infrared, inductive, capacitive, acoustic or optical.

In the context of the invention, "arranged in the region of the rear side of a striking plate" is understood to mean that the striking plate has a visible side facing away from the frame and a rear side facing away from the frame, and that this rear side covers a frame region in which the transmission module is arranged.

The basic locking function of the wing side arranged castle remains. However, by arranging the transmitter module in the area of the strike plate, it is now possible to control the transmitter module by using devices already installed on the building side to control the transmitter module. This will be explained in more detail below.

A deactivation of the locking function of the lock can be done using known per se components, for example using motors which drive the lock-side locking element and / or using a coupling device which establishes and interrupts a connection between a handle and the locking element.

The locking function can by a single locking element or even by a Multipoint interlocking be realized. The locking of a door or a window is the state that is designed by conventional insurance (household effects, burglary, building insurance, etc.) as insured closed state of the door or window, unlike a case without locking function, which only in a frame-side Trap recording is included and the door or window is unlocked.

The abovementioned actuators for electrically controlling the locking function are preferably supplied with energy on the lock side, in particular using batteries, accumulators and / or capacitors.

The energy for supplying the mentioned actuators can also be generated by using piezoelectric, thermoelectric and / or photoelectric effects. In any case, it is advantageous if the energy supply of said actuators is self-sufficient on the lock side, so that no power supply lines are required, which must be introduced from the frame side in the door or window sash.

Regardless of the principle of wireless communication between the transmitter module and the receiver unit, it is preferred that this communication be in an encrypted manner to prevent potential manipulation of the aforementioned actuators.

According to the invention, an operating unit is provided which communicates with the transmitter module via electrical lines. According to the invention, the operating unit and the electrical lines are part of an electric door or window opener system in which a wing-side latch can be released by means of a frame-side arranged electric opener. Such door or Fensteröffnersysteme are already present in a variety of existing buildings. The locking system serves, for example, to lock a building exterior door. The operating unit can be arranged as part of a door opener and / or door intercom in a subunit of the building, for example an apartment or an office. Such control units are connected via electrical lines, normally a two-wire arrangement, with a frame-side arranged electric opener. According to the invention, it is now possible for such existing in a building electrical lines for controlling the Transmitter module to use, since the transmission module is arranged in the region of the strike plate and thus in an area in which the building already existing electrical lines of conventional door or Fensteröffnersysteme open. In this way, the laying of additional lines is unnecessary.

In this context, it has also been recognized that a suitable transmitter module with a voltage between, for example, 5 and 28 volts (DC or AC) can be controlled and that this voltage range corresponds to a voltage range that is also used in conventional door or window opener systems. This makes it possible to control the transmission module without an additional power supply for the transmission module would have to be provided. In particular, it is not necessary (but still conceivable) to provide the transmitter module by means of a power supply with energy, which would have to be arranged on the building side, and in turn would have to be connected to the power supply of the building.

It is particularly advantageous that said electrical lines do not have to be changed in the form of a two-wire arrangement. Furthermore, it is not necessary to lay more wires and / or to adapt the course of existing lines.

In the event that the transmitter module is not driven in a potential-afflicted manner as described above, it is also possible to drive the transmitter module potential-free. In this case, it is preferred that an energy storage unit, for example a battery, an accumulator or a capacitor is arranged in the immediate vicinity of the transmission module.

When activating the transmission module for sending a control signal to the receiving unit, it is possible that the release of the locking function by appropriate optical and / or acoustic signals whose duration and intensity is controlled, is displayed.

Moreover, it is possible that the duration for which the locking function is deactivated, is independent of the duration of operation, with which a person operates the operating unit.

In a further preferred embodiment, it is provided that the transmission module comprises a switch, in particular manually actuable, which triggers a control signal in an actuating position, which deactivates the locking function of the lock permanently or for a predefinable period of time. Such a switch is modeled on a mechanical shift lever, which in conventional door or Fensteröffnersystemen allows permanent release of a wing-side trap. In this way, a door or a window, which with the inventive Locking system is kept for the duration of the operation of said switch or for a predetermined period of time in an open state, for example, to facilitate delivery of goods or moves.

The locking system according to the invention is suitable for different locks, in particular for different locking elements. For example, the locking element is designed in the form of a latch bolt. Such a latch bolt can be actuated, for example, by means of a pusher and / or via a lock cylinder. The electrically controllable locking function may be that a coupling device is provided between the latch bolt and the pusher and depending on the coupling state, a mechanical connection between the pusher and the latch bolt is made or not.

In the event that the locking element is designed in the form of a latch bolt, it is preferred if the striking plate has a latch opening corresponding to the latch bolt. In this case, the transmission module is preferably arranged outside the case passage opening, in particular in the region of a latch passage opening. This can be closed by the transmitter module, if the door lock no Latch has, which is arranged at the height of the bolt passage opening.

In the event that the lock has a locking element in the form of a bolt, which is arranged at the level of a bolt passage opening of the striking plate, it is preferred if the transmission module is arranged at the height of a case passage opening. In this case, it is possible to form the trap not as a latch bolt but as a "normal latch" without a latching function. Preferably, the case passage opening of the striking plate is followed by a trap receiving space arranged at the rear, which is bounded in particular by the housing of the transmission module.

The transmitter module preferably has the same dimensions as an electric opener to enable a "normal trap" of a conventional electric door or window opener system. In this way, on the frame side, in particular when converting from an existing conventional system to the system according to the invention, no additional space for the arrangement of the transmission module must be created. Furthermore, it is ensured that the space previously occupied by the electric opener of the conventional system is filled by the transmission module. In this way, it is not necessary to obscure resulting cavities with screens or similar additional components in the course of retrofitting.

The invention further relates to a method for producing a locking system.

The present invention has the further object of specifying a method with which a locking system is particularly simple to assemble.

This object is achieved in that, starting from an already installed in a building electric door or window opener system in which a wing-side latch is releasable by means of a frame-side electric opener and in which an operating unit for actuating the electric opener is provided by means of electrical lines, a connection of the electrical lines is interrupted to the electrical breaker and instead a connection of the electrical leads is made to a transmitter module, so that the transmission module via the electrical lines by means of the control unit is controlled.

Embodiments and advantages of the method according to the invention have already been described above with reference to the locking system according to the invention. These embodiments and advantages are referred to.

Further features and advantages of the invention are the subject of the following description and the drawings of a preferred embodiments.

In the drawing, various locking systems are shown, the respective parts are wing side or frame side to arrange. A first locking system comprises the in FIG. 1 and FIG. 2 shown components, a second locking system in FIG. 1 and FIG. 3 shown components, a third locking system in FIGS. 4 and 6 illustrated components, a fourth locking system in Figures 5 and 6 shown components, a fifth locking system in Figures 5 and 6 shown components, and a sixth locking system in Figures 5 and 7 illustrated components.

A lock designed to be arranged on a wing of a door or window (not shown) is shown in FIG FIG. 1 represented and designated there in total by reference numeral 10. The lock 10 comprises a lock case 12 and a cuff 14 and a locking element 16 in the form of a latch bolt 18. The latch bolt 18 is always operable from an inside 20 of the door or window sash by means of a handle in the form of a pusher 22 (panic function).

The lock 10 has a two-part pusher 24, which on the one hand produces a required for the panic function, permanent connection between the pusher 22 and the latch bolt 18 and on the other hand independent control thereof of the latch bolt 18 from an outer side 26 of the lock 10 ago.

On the outer side 26 of the lock 10, a further handle, for example in the form of a pusher 28, is arranged. An operative connection between the pusher 28 and the latch bolt 18 is by means of a coupling device 30, which in FIG. 1 is shown schematically controlled. The control of the coupling device 30 by means of a control device 32 also shown only schematically, which in turn is coupled to a receiving unit 34. The control device 32 and / or the receiving unit 34 are supplied with energy by means of an energy store 36, preferably a battery. The energy store 36 is preferably arranged at a height of the lock housing 12, on which a lock element separate from a latch is arranged in conventional locks (see also FIG FIGS. 4 and 5 ).

The lock 10 further includes a lock cylinder 38.

The above with reference to FIG. 1 described lock, for example, in the front door wing of a Multi-family house be arranged. The latch bolt 18 cooperates with a case passage opening 40 of a frame side, so stationary and building fixed arranged strike plate 42 together. The use of the latch bolt 18 has the advantage that the door or window wing can be locked in a closed state of the wing to the frame or the strike plate 42 of the frame, so that the corresponding door or window sash is considered "locked" also from an insurance point of view.

The strike plate 42 also has a bolt passage opening 44 arranged in the installed position below the case passage opening, which also permits the use of the strike plate 42 for conventional locks with a "normal catch" and a bolt separated from the latch. In the embodiment shown in the drawing, however, the bolt passage opening 44 is closed and by a part of the housing 46 of a transmission module 48th

The transmission module 48 is designed to communicate with the reception unit 34 of the lock 10. To control the transmitter module 48 electrical lines 50 are provided, which are arranged on the building side and in particular by electrical lines of a conventional electric door or window opener system are formed with which a "normal case" frame side (eg via an electric door opener) is releasable.

The electrical lines 50 are connected to an operating unit 52, which is arranged for example in a residential unit of the apartment building. An actuation of the operating unit 52 generates an energy pulse which triggers a transmission pulse of the transmission module 48, which is received by the reception unit 34 of the lock 10. The control unit 32, upon receiving such a signal, controls the coupling device 30 so that an operative connection between the pusher 28 and the latch bolt 18 is established. In this way, a person who is to be let into the building presses the pusher 28 not into space, but presses the latch bolt 18 so that it is drawn into the lock housing 12 and the latch bolt 18 out of engagement with the case passage opening 40 of the strike plate 42 passes and the front door can be opened from the outside. The described opening process can thus be controlled from the apartment of the apartment building, although the lock 10 was locked in its initial state.

An in FIG. 3 illustrated strike plate corresponds from its basic structure forth the strike plate 42 according to FIG. 2 , The peculiarity of the arrangement according to FIG. 3 consists in that the transmission module 48 has a switch 54 which triggers a control signal of the transmission module 48 for the receiving unit 34, which activates the coupling device 30 and thus the locking function of the lock 10 permanently or for disabled a predetermined period of for example a few minutes or a few hours. Since the switch 54 is arranged on the visible side 56 of the striking plate 42, the switch 54 is accessible only when the door or window wing on which the lock 10 is arranged, is open.

The transmission module 48 extends from the visible side 56 of the striking plate to the rear and is arranged on the rear side 58 of the striking plate 42.

Both FIGS. 4 and 5 locks shown 10 locking elements 16 are provided in the form of bars 60, which cause independent of a likewise provided case 62 locking the corresponding door or window sash. A locking of the respective latch 60 can be triggered in a conventional manner by actuating an additional latch 64.

The locks 10 can profile cylinder 38 (see FIG. 4 ) or even a double knob cylinder 68 (see FIG. 5 ) exhibit. On the outside 26 of the lock 10, a pusher 28 (see FIG. 4 ) or a knob 70 (cf. FIG. 5 ).

The lock 10 according to Fig. 4 also includes an energy store, in particular in the form of a battery. These is preferably located in a compartment adjacent the latch 62 which has a cover 66. In the lock 10 according to Fig. 5 it is a self-locking mechanical panic lock, the coupling device 30 is preferably disposed within the double knob cylinder 68. The control unit 32, the receiving unit 34 and energy storage in the form of batteries are preferably arranged within the inside arranged part of the double knob cylinder 68. The lock nut is in one piece and unlike the locks 10 according to FIGS. 1 and 4 not electrically aufkuppelbar, but constantly connected to the lock mechanism (panic function).

One with the locks 10 according to FIGS. 4 and 5 corresponding frame-side part of a locking system is in FIG. 6 and in FIG. 7 shown. This frame-side part comprises a strike plate 42 with a latch passage opening 44 for insertion and removal of the latch 60 of the locks 10 according to FIG FIGS. 4 and 5 , The strike plate 42 also has a case passage opening 40 for the passage of the latch 62 of the locks 10 according to FIG FIGS. 4 and 5 on.

On the back 58 of the lock plate 42, a transmission module 48 is arranged, the housing 46 has at least substantially dimensions, which an electric opener to Releasing a trap of a conventional door or window opener system correspond. The housing 48 of the transmitter module 48 may also have a (not operable or non-rotatable, but laterally adjustable) latch holder element 72 which would be actuated and rotatable in electrical openers by means of the electrical lines 50 and by means of the control unit 52 to release the latch 62. According to the invention, a transmission module 48 is provided, whose housing 46 has a trap receiving space 74 for receiving the latch 62 of the locks 10 FIGS. 4 and 5 limited.

About the frame-side part according to FIG. 6 a locking system is provided, it is advantageous if a switch 54 (for example in the form of a shift lever) is provided, cf. FIG. 7 , The switch 54 is manually operated and triggers when actuated a control signal of the transmission module 48, which responds to the receiving unit 34, which activates the coupling device 30 (coupled) and thus the locking function of the lock 10 according to FIG. 4 or FIG. 5 permanently or for a predefinable period of, for example, a few minutes or a few hours disabled. Since the switch 54 is arranged on the visible side 56 of the striking plate 42, the switch 54 is accessible only when the door or window wing on which the lock 10 is arranged, is open.

The lock 10 according to Fig. 4 operates as follows: An actuation of the operating unit 52 generates an energy pulse that triggers a transmission pulse of the transmission module 48, which is received by the receiving unit 34 of the lock 10. The control unit 32, after receiving such a signal, controls the coupling device 30 in such a way that an operative connection between the pusher 28 and the latch 62 and the latch 60 is established. In this way, a person who is to be let into the building pushes the pusher 28 not into space, but operates the latch 62 and the latch 60 so that they are retracted into the lock housing 12 and the latch 62 and the latch 60 disengaged with the case passage opening 40 and the latch passage opening 44 of the strike plate 42 according to Fig. 6 or Fig. 7 reach and the front door can be opened from the outside. The described opening process can thus be controlled from the apartment of the apartment building, although the lock 10 was locked in its initial state.

The lock 10 according to Fig. 5 operates as follows: An actuation of the operating unit 52 generates an energy pulse which triggers a transmission pulse of the transmitting module 48, which is received by the receiving unit 34 of the double-knob cylinder 68. The control unit 32, after receiving such a signal, controls the coupling device 30 in such a way that an operative connection is made between an outer knob of the double-knob cylinder 68 and the latch 62 and the latch 60. In this way, a person turns in the building is to be let in, the outer knob not into the void, but the latch 62 and the latch 60, so that they are drawn into the lock housing 12 and the latch 62 and the latch 60 out of engagement with the case passage opening 40 and the latch passage opening 44 of the Striker plate 42 according to Fig. 6 or Fig. 7 reach and the front door can be opened from the outside. The described opening process can thus be controlled from the apartment of the apartment building, although the lock 10 was locked in its initial state.
