Description

The present invention relates to a roller shutter system comprising at least one roller shutter, a guide for laterally guiding the roller shutter and a roller shutter box, in which the roller shutter can be wound up.

Modern and in particular energy-efficient buildings are increasingly equipped with floor-to-ceiling windows to allow more light and solar heat into the building. To control the light and heat balance, the windows can be provided with a roller shutter system, since lowered roller shutters form, among other things, an additional heat-insulating layer in the region of the windows. In addition, the outer walls of low energy buildings are typically clad with thermal insulation, e.g. B. with a 12 cm thick Styrofoam layer.

To supply the interiors of the buildings with fresh air, the floor to ceiling windows can be opened. In order to prevent objects or persons from falling out of an open window, it is known to attach a so-called French balcony to the building in the area of the window. It is in the French balcony is not a balcony in the true sense, but rather a railing or another balustrade element, which is attached to a floor to ceiling windows on the building and only minimally protruding from the facade.

A French balcony must be firmly anchored to the building in accordance with the relevant building regulations and generally accepted rules of technology. This means that in some cases very expensive constructions, in particular through the insulating layer and past the roller shutter system, have to be attached to the building. These are on the one hand very costly and on the other not always easy to manufacture.

An object of the present invention is therefore to provide a simple way increased security for floor to ceiling windows.

The object is achieved in that a roller shutter system of the type mentioned is provided, which is particularly characterized in that the guide has two pairs of opposing guide rails, wherein the shutter for pulling up or lowering is guided in a first pair of guide rails and the balustrade element is arranged in a second pair of guide rails of the roller shutter system.

According to the invention, therefore, an integration of the balustrade element is provided in the roller shutter system, so that the balustrade element does not need to be attached to the building as before by means of elaborate constructions outside the shutter system. By virtue of the fact that the guidance of the roller shutter system comprises two pairs of guide rails, one of which is assigned to the balustrade element and the other pair to the roller shutter, it is also ensured that the roller shutter is actuated in the usual manner and, in particular, lowered completely despite the balustrade element can.

By combining two pairs of guide rails to form a guide, the roller shutter system according to the invention can also be manufactured in a simple manner and reliably installed in a window opening of a building wall, whereby the guidance of the roller shutter system is flush with the building wall or an insulating layer additionally attached to the building wall that the management of the shutter is perceived as part of the building wall. Furthermore, the roller shutter system can be attached to the window floor of a window.

Advantageous embodiments of the invention are described in the dependent claims, the description and the drawings.

According to an advantageous embodiment, the balustrade element is arranged in an area of the guide which is at a distance from and opposite the roller shutter box. This leads to a stiffening of the entire shutter system and thereby also allows a more accurate guidance of the shutter in its guide rails. Preferably, the roller shutter box is arranged in the region of an upper end of the guide, in particular arranged above the window, while the Ballustradenelement is arranged in the region of a lower end of the guide.

Preferably, the balustrade element is firmly anchored in the guide, z. B. screwed into this, glued and / or pressed. This allows the balustrade element to take over the function of a conventional French balcony in a simple and reliable manner.

By anchoring the balustrade element in the guide, the balustrade element is fixed in the second pair of guide rails. As a result, the security of the roller shutter system is additionally increased because the balustrade element is not along the guide rails, z. B. from bottom to top, can be moved.

The balustrade element can be made of different materials as well as in different forms. It can, for. Example of glass, bulletproof glass, Plexiglas, frosted glass, plastic, stainless steel, aluminum or steel and be formed in the form of a disc or plate or alternatively in the form of a lattice railing. This allows the architect or contractor or builder to choose from a variety of materials to give the building its desired look.

According to another embodiment, in the second pair of guide rails, i. H. So in the same pair of guide rails, in which the balustrade element is arranged, an insect or pollen guards out. This can be pulled up or lowered as needed and prevents insects or pollen can enter the room behind the shutter system to z. B. Allergy sufferers to allow a more pleasant stay in the room. The insect or pollen protection grid can be wound up in the roller shutter box in addition to the roller shutter. Also, a shade may be disposed in the second pair of guide rails which is disposed in the second pair of guide rails instead of an insect or pollen protective grid or in addition to an insect or pollen protective grid.

The insect or pollen protection grid can preferably be lowered so far that it rests on the balustrade element in the closed state, so that it is ensured that no insects or pollen can pass between the insect or pollen protection grid and the balustrade element.

According to a further embodiment, a third pair of opposing guide rails is arranged in the guide. In this case, the insect or pollen guard is placed in the third pair of guide rails and can be lowered in the third pair of guide rails so that it can then close with a guide end, which is located in the region of the lower end of the guide. This ensures that even using a lattice railing as a balustrade element no insects or pollen can get into the room behind the shutter system. Also, a blind may be disposed in the third pair of guide rails which is disposed in place of an insect or pollen protective grid or in addition to an insect or pollen guard in the third pair of guide rails.

According to a further embodiment, the roller shutter is mounted by means of springs or seals in the first pair of guide rails. Accordingly, the insect or pollen protection grid and / or the blind can be mounted by means of springs or seals in the second pair of guide rails or in the third pair of guide rails. The piping ensures that the respective guide rails or the roller shutters and the insect or pollen guards are not damaged by abrasion caused by intensive use. The piping also contributes to a better seal between the shutter and the guide, thereby reducing heat exchange.

According to a further embodiment, the roller shutter can be wound up or unwound by means of an associated drive motor in order to pull up or lower the roller shutter. The drive motor allows weaker people, such. As young children to operate the shutter. Furthermore, the roller shutter controlled by a timer can be moved up or down at predetermined times, which contributes not least to an increase in burglar resistance.

Accordingly, the insect or pollen protection grid can be driven by a motor. In this case, the insect or pollen protection grid can be coupled to the roller shutter or moved independently of the roller shutter.

According to a further embodiment, at least one motion sensor is provided to detect whether a person or a vehicle approaches a building equipped with the roller shutter system or with the roller shutter systems from the outside. In this case, the sensors can be arranged so that they cover a safety-relevant surrounding area and that they cause an automatic shutdown of the shutters upon detection of a person or a vehicle in the safety-relevant environment area.

According to a further embodiment, the roller shutter system is a fire protection roller shutter system, which prevents by the appropriate choice of material in case of fire that the fire can spread quickly.

The amount around which the shutters 16 . 17 is shut down when arming the system is by means of one of the switching device 36 included adjusting means 40 , z. B. knob, adjustable and should move in a range of about 10 cm to 50 cm and, for example, be about 20 cm. Through the adjustment means 40 Ultimately, a period of time during which the drive motors 18 when arming the system, or the number of revolutions of the drive motors 18 predetermined, which is required to the shutters 16 . 17 to lower the predetermined amount.

Partially lowering the shutters 16 . 17 on the one hand signals the armed state of the system. On the other hand, the shutters can be 16 . 17 completely close faster from this partially lowered position when a suspicious person approaches the building 10 approaches. Nevertheless, in the armed state still enough light through the windows 13 . 14 in the building 10 get to the quality of life within the building 10 not significantly affect.

The switching device 20 The present embodiment further includes a timing circuit 42 that allows all shutters 16 . 17 or only selected shutters 16 . 17 automatically shut down or drive up at pre-programmed times, thereby pretending to be homeowners. Such a timer 42 is also called holiday circuit.

It is possible the switching device 36 to turn on and at the same time the holiday circuit 42 to activate. In this case, the shutters 16 . 17 completely lowered at predetermined intervals or partially driven back up again, ie until the predetermined focus.

Is through one of the sensors 22 the intrusion of a suspected person into the security-related surrounding area of the building 10 detected, so gives the sensor 22 a corresponding signal to the switching device 36 out. The switching device 36 in turn gives a corresponding signal to the drive motors 18 off to the shutters 16 . 17 completely shut down.

In addition, the switching device 36 with an alarm system 44 be coupled, which upon detection of a suspicious person in safety-related environment by the switching device 36 is activated and emits a visual or audible warning signal or notifies a building supervisor, security company or police department.

A deactivation of the armed roller shutter system, as already mentioned, in principle by a corresponding actuation of the trigger device 38 be achieved. The switching device 36 in this case ensures that the shutters 16 . 17 be completely pulled up again. Such deactivation of the system may occur regardless of whether a suspect has been detected, ie the shutters 16 . 17 completely lowered or not.

Is the holiday circuit 42 activated and become the shutters 16 due to the penetration of a suspicious person in the monitored environment area completely down, so the switching device 36 be configured so that the shutters 16 . 17 at least for a predetermined period of time or up to a predetermined time, e.g. B. until the next morning, remain in the fully lowered state and only then in the by the holiday circuit 42 predetermined rhythm can be driven up or down.

At the in 10 embodiment shown are the holiday circuit 42 and the control outputs 34 for the drive motors 18 in the switching device 36 integrated, but of course also in separate circuits (not shown) may be integrated.
