Definitions

• Alarm-triggering locking device for the closing and / or hinge area of a to be secured
• the invention relates to an alarm-triggering locking device for the closing and / or hinge area of a door or window to be secured, with a first holding device for the locking device to be overcome by the action of force, with a second device by the action of force or more difficult to overcome holding device for the locking device, and with means triggering an alarm when the first holding device is overcome, the movement of the locking device in the opening direction of the door or window being limited after the first holding device has been overcome by the second holding device.
• the basic mode of operation of this locking device is known from DE-A-42 21 585 and consists in that, in the event of a break-in by the action of force, a first holding device is first overcome, but an alarm is then triggered immediately. This is preferably a silent alarm trigger, in which the opening of an alarm center is reported. After triggering the alarm, however, the burglar is now prevented from entering the building by the second holding device, which offers him greater resistance than the first holding device. He now has to make greater efforts to also overcome this second holding device, the time required for this being given to the auxiliary workers or gives the police the opportunity to get to the burglary site.
• the known locking device is designed in its entirety as an additional securing element, which means a great deal of material and cost in the manufacture and assembly.
• the interaction with the fitting already arranged in the door and the hinges arranged anyway is problematic and these would have to be redesigned so that conventional fittings cannot be used.
• An object of the present invention is to provide an alarm-triggering locking device of the type mentioned, which is easier to assemble and in which the conventional door or window fittings can be retained.
• the first holding device is the fitting arranged or integrated in the window or in the door and the second holding device is an additional security device fitted to the door or window, at least one locking part being in the locked state engages behind or in at least one counter-stop element and the closure part strikes the counter-stop element laterally with a delay after overcoming the first holding device and a subsequent opening movement of the door or window leaf and inhibits the opening movement.
• alarm sensors on the window or door can be used, e.g. B. magnetically, mechanically or optically triggerable switch or current and / or voltage-loaded tear-off wires, which are arranged in particular on predetermined breaking plates.
• alarm-triggering means can be arranged on the first or second holding device or independently of them directly on the window or the door.
• the closure part is designed as at least one displaceable locking rod which can be brought into engagement with an opening of the counter-stop element, the locking rod being arranged on the door or window sash and the counter-stop element on the door or window frame are or vice versa.
• a pole can be very massive be trained so that overcoming them requires a large temporal commitment of the burglar or even discourages him.
• at least two locking bars are arranged on the inside of the door or window sash so that they can be displaced in opposite directions, the corresponding counter-stop elements, in particular in the form of a bracket, for attachment to opposite points of the door or window frame are provided. This version enables easy installation with very good burglar protection.
• the at least one locking rod can preferably also be displaced by the fitting integrated in the door or window sash for opening and closing the door or window, so that normal use of the window or door is possible without sacrificing comfort.
• the at least one locking part has at least one projection which engages in an opening of the counter-stop element, the locking part being arranged on the door or window sash and the counter-stop element on the door or window frame or vice versa .
• This arrangement is particularly suitable for securing the hinge side of a door or window sash, the closure part being designed as a sheet metal part, the at least one tab-like projection of which is at a distance from the counter-stop element, which is in the form of a bracket, the at least one tab-like projection when opening the Door or window is pivoted freely in the counter-stop element, so that no loss of comfort has to be accepted in normal use of the door or window.
• a further advantageous constructive embodiment of the invention consists in that the at least one locking part is designed as a locking bolt which is displaceably guided in a holding part, that a locking element is inserted into the Holding part engages, the locking bolt engages in the locked state in an opening of the locking element or extends through this, and wherein an inner surface area of the opening or a guide channel for the locking bolt forms the counter-stop element, and that the holding part on the door or window frame and the locking ⁇ element is arranged on the door or window sash or vice versa.
• the locking bolt can be displaced in the opening direction on at least one side of the locking element to form a spaced counter-stop element in the locking channel.
• a predetermined breaking element inhibits displacement of the locking bolt in the opening direction, the predetermined breaking element being designed in particular as an alarm-triggering means.
• the first retaining device is first overcome according to the invention, which leads to a deflection of the locking bolt in the opening direction and consequently to a breakage of the predetermined breaking element and the alarm being triggered.
• the locking bolt can be moved by an electrical actuator for locking and unlocking.
• the alarm system is automatically locked when the alarm system is switched on or armed.
• a plurality of locking bolts can be displaced simultaneously and engage in corresponding openings in the locking element, which is in particular in the form of an L-shaped plate.
