Description

The invention relates to a roller shutter gate system with a rolling grill curtain, which can be wound from a winding shaft in a closed position of the rolling grill curtain and wound on the winding shaft in an open position of the Rollgitterbehang, which winding shaft is rotatably driven via a shaft drive, with a gate control in Control connection is, 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 for closing window or door openings in buildings. 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 rods 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 ingress of an unauthorized person and to prevent the intrusion into a building by the rolling grill gate system, it has also already created RollgitterToranlagen, the Rollgitterbehang cooperates with corresponding locking bolts. However, such locking bolt on the usual Rollgitterbehängen are very complex in their construction and handling.

From DE69304799T2 a shutter or the like closure means is already known, which serves inter alia for closing a window, door or the like building opening. Serving as a closure means and guided on both sides in a pair of slides shutters is to be rolled up on a roll-up and unrolled from the reeling shaft, which Aufrollwelle is rotatably driven by means of a drive motor. On the last slat of the roller shutter, a grinding member is fixed, which rubs on the rough or roughened inner surface of the slide rails. The friction of the grinding member on the inner surface of the slide generates vibrations that can be detected by means of a vibration sensor. The occurrence of vibrations on the vibration sensor can, among other things trigger the message of a break-in attempt. Since the inner surfaces of the slides must be roughened, the production of the known roller shutter is so far associated with an additional manufacturing effort. In addition, there is a risk that in an unauthorized, but careful pushing the shutter shutters vibrations are avoidable and the message of a burglary attempt erroneously omitted.

From DE202013104347U1 an insect screen is already known, which is associated with a door or a window. The insect screen, which can be wound onto a shaft and can also be unrolled by this shaft, is connected to a sensor which detects the opening of the associated window or associated door. As soon as this sensor detects the opening of the associated window or associated door, the insect screen, unless it is already rolled out of the shaft, unrolled by means of the shaft drive in front of the window or door opening to the opening of the associated window or the associated door in the Essentially seal the insect. However, the possibility of detecting and signaling unwanted pushing up of the insect screen is neither necessary nor addressed in the case of the insect screen known from DE202013104347U1.

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

The achievement of this object is in the rolling grill 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 controller forwards the signal to the alarm system, which triggers the at least one signal generator.

The roller grille door system according to the invention has a rolling grill hanging, which can be unrolled by a winding shaft in a closed position of the rolling grill curtain and on the winding shaft in an open position of the Rollgitterbehangs. 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 communication with an alarm system, which has at least one acoustic and / or optical signal generator. The RollgitterToranlage invention has at least one position sensor that 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 door system according to the invention.

Since the usual Rollgitterbehänge can be pushed up so far only on one side that a person can creep through unauthorized, it is advantageous if both sides in the region of 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 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 cooperate with at least one permanent magnet on Rollgitterbehang.

In order to effectively protect the burglar alarm integrated into the rolling grill invention according to unauthorized manipulations, it is advantageous if the Rollgitterbehang has on its bottom side Behangende a final profile and if the at least one, the at least one reed contact associated permanent magnet in the region of the end profile and in particular protected in the profile interior of the end profile is arranged.

For the same purpose, it may be advantageous if at least one of the Behangführungen 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 gate system according to the invention 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 contacts Contact is closed, although the shaft drive has not yet signaled to the door control a drive state corresponding to the closed position of the Rollgitterbehangs, 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 at least one of the reed contacts with only half lowered roller grille hanging, the reed contact is closed, but the door control and the alarm system in control connection with it will simultaneously realize that the permanent magnet is still in this intermediate position of the roller grille curtain can not 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 drawings. The invention will be described in more detail below with reference to a preferred embodiment.

In the figures 1 to 5, a roller shutter gate system 1 is shown, which has a rolling grill curtain 2. The rolling grille door system 1 shown here is provided for closing a window or door opening in a building. The Rollgitterbehang 2 of the rolling grille door system 1 shown here is to be wound on a winding shaft in an open position of the Rollgitterbehangs or unrolled from the winding shaft into the closed position of the Rollgitterbehangs 2 shown in Figure 1. The winding shaft not shown here is rotatably driven via a shaft drive, which is in control connection with a gate control. The door control is connected to an alarm system in signal connection, which has at least one acoustic and / or optical signal generator.

As can be seen in Figures 2, 4 and 5, the roller shutter gate system 1 at least one position sensor 3, which sends a signal to the gate control at a caused without the shaft drive pushing up the Rollgitterbehangs 2 from its closed position. 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 the optical and / or acoustic signal generator is triggered, the persons located in the area of the roller shutter door system are informed about unauthorized manipulation of the roller grill curtain 2.

In order to prevent a one-sided pushing up the Rollgitterbehangs and a crawl through a person through the created between the bottom and Bodenseitigem Behangende space, it is advantageous if both sides in the sliding path of the Rollgit terbehangs 2 each at least one position sensor 3 is provided.

From a comparison of Figures 1 to 5 it can be seen that the Rollgitterbehang 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 curtain guides 4 may be formed as a particular U-shaped guide rails. From a comparison of Figures 1 to 3 and 5 it can be seen that the rolling grill curtain has corrugated bars 5, wherein adjacent corrugated bars with the wave peaks of their waveforms abut each other such that the 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 embodiment shown here, the at least one position sensor 3 is formed as a reed contact, which cooperates reed contact with at least one permanent magnet 8 on Rollgitterbehang. The Rollgitterbehang 2 has on its up and unrollable bottom end Behangende a final profile 9, in the profile interior of the ReedKontakt associated permanent magnet 8 is arranged protected.

In order to accommodate protected as a position sensor 3 reed contacts protected against manipulation, these reed contacts are arranged on a guide base 10 at least one of the curtain guides 4.

In the rolling grille door system 1 shown here, it is provided that the door control sends a signal to the alarm system when the at least one trained as a reed contact position sensor 3 is closed, although the shaft drive is not yet one of the closed position of the Rollgitterbehangs corresponding drive state has signaled to the gate control and that the alarm system triggers the receipt of the signal, the at least one optical and / or acoustic signal generator. In order to rule out manipulation of the RollgitterToranlage 1, the gate control brings the closing of the at least one reed contact in connection with the closed position of the Rollgitterbehanges 2. So if a permanent magnet is held only half lowered Rollgitterbehang 2 to the at least one reed contact, this is Although the reed contact is closed, the gate control simultaneously realizes that the permanent magnet 8 assigned to the reed contact can not yet be at the reed contact in this intermediate position of the rolling grill curtain and triggers a corresponding alarm.
