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 gate control with an alarm system in

Signal connection is the at least one acoustic and / or optical

Signaling device has.

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 RollgitterToranlagen have corrugated rods, 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 rolling grill behanges, especially if they have a higher installation height, can easily push up. It is also possible to push this Rollgitterbehänge so far up that in the space between the bottom on the one hand and the end profile on the bottom

On the other hand, a person can crawl through it.

To prevent the intrusion of an unauthorized person and the

To prevent burglary in a building by the rolling grill gate system, one has also already created rolling grill gate systems whose 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 help of the rolling grille door system according to the invention, the winding shaft is above the

Window or door opening positioned. The winding shaft is rotatably driven by a shaft drive, which is in control connection with a gate control. These

Gate 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 in a caused without the shaft drive pushing up the Rollgitterbehangs from the

Closed position sends a signal to the gate control. Because one without the

Shaft drive causes pushed up the Rollgitterbehangs on an unauthorized pushing up the curtain for the purpose of crawling a person close, the signal is forwarded by the gate control to the alarm, which now at least one acoustic and / or optical

Sounder triggers and thus effectively indicates a break in the rolling grille door 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 sliding path of the

Rollgitterbehangs 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 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 cooperate 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 roll-grid 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 in the

Profile interior of the final profile is arranged.

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. This is because the guided in the blinds guided

Roller grille hanging 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 on the one hand and the guided therein

Roller grille hanging on the other hand arranged.

To an unauthorized influence on the rolling grilles according to the invention

To prevent gate integrated reed contacts using a permanent magnet, a preferred embodiment according to the invention provides that the gate control sends a signal to the alarm system when the at least one reed contact is closed, although the shaft drive is not yet one of the closed position of the Roller grille hanging corresponding drive state to the

Tortrol has signaled, and that the alarm system after receipt of the signal triggers the at least one signal generator. Thus, if a permanent magnet is manipulatively applied to at least one of the reeds with only a half-lowered roller blind hanging

Although the reed contact is kept closed, the gate control and the alarm system in control connection with it are simultaneously true that the permanent magnet in this intermediate position of the roller shutter curtain can not yet be at the reed contact 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 drawing.

The invention will be described in more detail below with reference to a preferred embodiment.

Closing a window or door opening provided in a building. Of the

Roller grille curtain 2 of the rolling grille door system 1 shown here is to a

Winding shaft in an open position of Rollgitterbehangs wound up or from the

Winding shaft in the closed position shown in Figure 1 of the Rollgitterbehangs 2 unrolled. The winding shaft not shown here is rotatably driven via a shaft drive, which is in control connection with a gate control. The

Gate control is in signal communication with an alarm system, which has at least one acoustic and / or optical signal generator.

As can be seen in FIGS. 2, 4 and 5, the roller shutter door system 1 has at least one position sensor 3 which, when the roller grille curtain 2 is moved up without the shaft drive, is in its closed position

Sends signal to the gate controller. Since pushing up the rolling grill curtain 2 from its closed position without involvement of the shaft drive can close an unauthorized manual pushing up the Rollgitterbehangs 2, the gate control forwards the signal to the alarm system that triggers the at least one signal generator. When triggering the optical and / or acoustic

Signalers the persons located in the area of the roller shutter door system are pointed to an unauthorized manipulation of the rolling grill curtain 2.

In order to also a one-sided pushing up the Rollgitterbehang and a

Crawling of a person through the between ground and ground level

To prevent hanging created free space, it is advantageous if at least one position sensor 3 is provided on both sides in the region of the sliding path of the Rollgitterbehangs 2 each.

From a comparison of Figures 1 to 5 it can be seen that the rolling grill curtain is guided on both sides of its hanging longitudinal sides in each case a Behangführung 4 slidably. The provided on both sides of the Rollgitterbehangs 2

Behangführungen 4 can be designed as particular U-shaped guide rails. It can be seen from a comparison of FIGS. 1 to 3 and 5 that the rolling grill curtain has corrugated bars 5, wherein adjacent corrugated bars rest against one another with the wave peaks of their wave forms in such a way that the corrugated bars

Waveforms of the adjacent corrugated bars 5 form a series of diamonds. In order to prevent a penetration through the diamonds formed between adjacent corrugated bars 5, an undefined rectilinear transverse bar 6 is provided between the adjacent corrugated bars 5. In this case, the adjacent corrugated bars 5 and the transverse bar 6 provided between them are hingedly connected to one another by means of retaining clips 7, which retaining clips 7 engage on opposite wave peaks and the transverse bar 6 arranged between the wave peaks of adjacent corrugated rods 5.

In the exemplary embodiment shown here, the at least one position sensor 3 is designed as a reed contact, which reed contact cooperates with at least one permanent magnet 8 on the rolling grill curtain. The Rollgitterbehang 2 has at its up and unrollable bottom side Behangende
