DE10001226A1 - Security device for door or window has contact device operated by alternation in spacing between door or window unit and frame for activating alarm signal source - Google Patents

Abstract

The security device has an alarm signal source, e.g. a buzzer (9), activated by an alteration in the relative spacing between the door or window unit and the inner frame part (1) by insertion of a forcing tool, e.g. a screwdriver, using at least one contact device between the door or window unit and the frame, for providing an activation pulse for the supply current circuit for the alarm signal source.

Description

The invention relates to a signaling device for windows / Doors whose cane and / or casement frames made of a composite constructions exist such. Bp. The well-known wood-aluminum windows, their supporting wooden frames covering outer panels made of aluminum have a violent prying open the window / door sash early signaled from outside.

The safety devices known for such a purpose have various disadvantages: magnetic or bolt contacts, which is mainly mounted on the window / door frame on the room side are only effective if the violent prying open already succeeded and appropriate damage has occurred. The acting person has enough time, the break-in target to achieve as they have the entire intervention time available Has. The same disadvantages also apply to room surveillance directions, so-called motion detectors. Monitoring devices for outside, the movements and / or heat sources in the window / Signaling the door area have another disadvantage, because of their sensitivity, they often trigger false alarms. Another disadvantage of almost all known alarm devices is the fact that they are specifically switched on or off need or require expensive additional equipment, the false alarms exclude or ensure the function at the desired time.

The object of the present invention is a signal generator device to show that essentially without the pre mentioned disadvantages reliably and already at the beginning of the ge violent act triggers alarm.  

This task is solved with the characteristic features of the first claim.

In principle, the invention is based on the idea, even the smallest, changes in distance caused by the lever tool External panels to the supporting frame part, preferably on the frame to trigger a signaling device by switching between inner and the outer frame part a contact device is arranged so that the movement of the change in distance is transferred to this to interrupt or preferably to close a current leads and thus a signal integrated in the circuit encoder is triggered.

The advantages of the disclosed invention over the known, comparable devices are essentially the following:

• 1. The alarm is triggered at the beginning of the violent act and the risk of being discovered becomes incalculable for the perpetrator bar because the window / door is still closed.
• 2. The early alarm reduces the attempted break-in damage.
• 3. The shock effect is relatively large since the innovation is complete can be installed concealed.
• 4. The innovation can be a constantly armed device be without affecting regular operation and function of the window or the door. They are not additional Circumstances to be considered still require complex controls. In contrast to comparable known devices Incorrect switching and thus false alarms or unsecured windows locked out.

An advantageous embodiment of the invention is in protection claims 2 and 3 specified. A further development of the invention according to claim 2 allows the use of compact units easy assembly and especially for easy retrofitting windows / doors already installed. An arrangement as in Claim 3 simplifies the installation by the Double function of the holder and enables wiring  to a central main alarm system.

An embodiment of the invention is based on the drawing explained.

Shown is a section of the frame section of a wood-aluminum window in principle with floor frame ( 1 ) and floor frame cladding ( 2 ), casement ( 3 ) with cladding profile ( 4 ); the cladding profiles ( 2 ) u. ( 4 ) form an outer stop ( 5 ) when the window is closed. Cane frame ( 1 ) has a cylindrical recess ( 6 ) with a bore ( 7 ). In the recess ( 6 ) are arranged: 1 button cell ( 8 ) for power supply, a piezo buzzer ( 9 ) as an alarm, a contact point ( 10 ), plus and minus metal strips ( 11 ) and. ( 12 ) and a spring ( 13 ) fixing the contact point ( 10 ). A cylindrical extension ( 14 ) of the positive pole metal strip ( 11 ) with a contact pin ( 15 ) adjustable by means of a fine thread is arranged in the bore.

When a burglary tool (3/4) inserted to lever the casement in the stop (5), the locking device of the window changes before impair supply the position of the clothing Ver profile (2) to the floor frame (1). Via the contact pin ( 15 ) on the profile ( 2 ), this change in position closes the circuit via the contact point ( 10 ) between the button cell ( 8 ) and the piezo buzzer ( 9 ) and triggers an alarm.

Claims (3)

1. Safety device, the violent attempts to open the sash from the outside of windows / doors with frame and / or sash frame with doublings on the outside, which may be weather protection or decorative profiles or other covers or panels, especially in the known wood-aluminum windows or / and reacts to this with alarm or signaling, characterized in that a change in the distance of the outer doubling to the associated inner frame part, in particular in the frame by loosening, lifting, pressing or moving the doubling by a burglar tool, by at least one contact device, the direction between the frame part and the doubling is arranged and integrated into a circuit, recorded and converted into a pulse to interrupt or preferably close the circuit and thus to activate a signal or alarm transmitter coupled to the circuit. 2. Signaling device according to claim 1 characterized, that a preferably spring-loaded button or sensor or lever that space between doubling and frame and arranged partially or completely penetrating the frame  is the change in distance of the outer doubling to appropriate frame on a switch or a Kontaktinrich tion that is accessible from the inside Frame recess or is attached to the inside of the frame, for triggering a pulse, signal or alarm transmitter transmits. 3. Signaling device according to claim 1 characterized, that the coupling or connecting elements for fastening serve the outer doublings, which turn, clip, Twist clips or other holders can be used with a Signaling required contact mechanism equipped are.
