Description

The invention relates to a roller shutter gate system with a Rollgitterbehang, which can be wound from a winding shaft in a closed position of the Rollgitterbehangs and wound on the winding shaft in an open position of the Rollgitterbehangs, which winding shaft is rotatably driven via a shaft drive, which is in control connection with a gate control, said the door control is in signal communication with an alarm system which has at least one acoustic and / or optical signal generator.

Roller grille door systems are used to close window or door openings in structures. The previously known rolling grille door systems have a rolling grill hanging, which can be rolled up onto a winding shaft positioned above the window or door opening or can be unrolled from this shaft. In this case, the winding shaft for winding and unwinding of Rollgitterbehangs by means of a shaft drive rotatably driven. The Rollgitterbehänge previously known roller grille door systems have corrugated bars, wherein adjacent corrugated rods abut with the wave peaks of their waveform to each other such that the waveforms of the adjacent corrugated bars form a series of diamonds. In order to prevent a penetration by the diamonds formed between adjacent corrugated bars, an undefined rectilinear transverse bar is provided in each case between the adjacent corrugated bars. In this case, the adjacent corrugated bars and the transverse bar provided between them are hingedly connected to one another by means of retaining clips which engage retaining clips on opposite wave peaks and the transverse bar arranged between the wave peaks of adjacent corrugated rods.

The Rollgitterbehänge such Rollgitter gate systems regularly have so much game that this Rollgitterbehänge, especially if they have a higher installation height, can easily push up. It is also possible to push this Rollgitterbehänge far enough that on the other hand a person can crawl in the space between the bottom on the one hand and the end profile on the bottom side Behangende the Rollgitterbehangs.

In order to prevent the intrusion of an unauthorized person and to prevent the intrusion into a building by the rolling grill gate system, it has also been created rolling grille gate systems, the rolling grill hanging cooperates with corresponding locking bolts. However, such locking bolt on the usual Rollgitterbehängen are very complex in their construction and handling.

It is therefore an object to provide a roller shutter gate system of the type mentioned, in which an unauthorized crawling under the rolling grill curtain is effectively prevented.

The achievement of this object is in the rolling gate system of the type mentioned in particular that at least one position sensor is provided which sends a signal to the gate control at a caused without the shaft drive pushing up the Rollgitterbehangs from the closed position, and that the gate control Signal to the alarm system passes, which triggers the at least one signal generator.

The roller grille door system according to the invention has a rolling grill curtain, which can be unrolled from a winding shaft into a closed position of the rolling grill curtain and can be wound onto the winding shaft in an open position of the rolling grill curtain. In order to be able to close a window or door opening in a building with the aid of the roller shutter door system according to the invention, the winding shaft is positioned above the window or door opening. The winding shaft is rotatably driven by a shaft drive, which is in control connection with a gate control. This door control is also in signal connection with an alarm system, which has at least one acoustic and / or optical signal generator. The roller grille door system according to the invention has at least one position sensor, which sends a signal to the gate control at a caused without the shaft drive pushing up the Rollgitterbehangs from its closed position. Since a caused without the shaft drive pushing up the Rollgitterbehangs close to an unauthorized pushing up the blind for the purpose of crawling a person, the signal is forwarded by the gate control to the alarm, which now triggers the at least one acoustic and / or optical signal transmitter and thus effectively indicates a break in the rolling grille gate system according to the invention.

Since the usual Rollgitterbehänge can be pushed so far only on one side so that a person can creep through unauthorized, it is advantageous if both sides in the region of the sliding path of the rolling grill curtain each at least one position sensor is provided. If at least one position sensor is arranged on both sides in the region of the sliding path of the rolling grill curtain, a single-sided pushing up of the rolling grill curtain is also effectively signaled.

A preferred embodiment according to the invention provides that the Rollgitterbehang is guided on both sides of its curtain longitudinal sides in each case at least one Behangführung slidably. The curtain guides can be designed in a simple manner as guide rails.

A particularly simple and functionally reliable embodiment according to the invention provides that at least one position sensor or at least one of the position sensors is designed as a reed contact, which reed contact / which reed contacts each interact with at least one permanent magnet on the rolling grill curtain.

In order to effectively secure the burglar protection system integrated in the roll-grid curtain according to the invention against unauthorized manipulations, it is advantageous if the roller blind curtain has a closure profile on its bottom-side curtain end and if the at least one permanent magnet associated with the at least one reed contact is protected in the region of the closure profile and in particular is arranged in the profile interior of the end profile.

For the same purpose, it may be advantageous if at least one of the curtain guides the at least one reed contact are arranged on a guide base. If, in fact, the roller grate curtain guided in the drapery guides is in its closed position, the reed contacts arranged on the guide base of this drapery guides are also protected between the guide base of the drapery guide and the roller grate curtain guided therein.

In order to prevent unauthorized action on the reed contacts integrated in the rolling grille door system according to the invention using a permanent magnet, a preferred embodiment according to the invention provides that the gate controller forwards a signal to the alarm system when the at least one reed contact is closed is, although the shaft drive has not yet signaled the closed position of the Rollgitterbehangs corresponding drive state to the gate control, and that the alarm system after receipt of the signal triggers the at least one signal generator. Thus, if a permanent magnet is held manipulatively with at least one of the reed contacts, the reed contact is closed, but the door control and the alarm system in control connection with it are true at the same time that the permanent magnet in this intermediate position of the Rollgitterbehangs not yet at the reed contact can be and triggers a corresponding alarm.

Further developments according to the invention will become apparent from the following description of the figures in conjunction with the claims and the drawings. The invention will be described in more detail below with reference to a preferred embodiment.
