Roller shutter box

The invention relates to a roller shutter box, in particular for prefabricated houses, with a drive and bearing device for a roll-up shading element in a housing.

Roller shutters improve the heat and sound properties of windows and doors and also serve as burglary protection.

Roller shutters can significantly improve the thermal insulation effect of windows and doors in the cold season and prevent rooms from overheating in the warm season by avoiding direct sunlight.

Light and ventilation slots allow for pleasant light to enter while providing privacy, creating a comfortable living environment. When lowered, roller shutters can provide an extremely inexpensive and significant improvement in soundproofing, and lowered roller shutters provide significantly greater protection against burglary, as experience shows that windows with roller shutters are less likely to be forced open and a wide range of burglary protection systems can also be supplied for roller shutter constructions if required.

On the one hand, roller shutter boxes have so far been integrated as inconspicuously as possible into the external façade, while on the other hand, external roller shutter systems with a pleasant, rounded design have recently become increasingly popular. The box constructions, which are usually designed as semi-circular boxes, in conjunction with the side roller shutter guides, represent an architectural element which, usually in striking colors, helps to determine the flair of modern, youthful architecture.

.mti» ·· · ·· ·&diams;

In recent times, the long-standing roller shutter box has been used because it makes it easier to integrate a roller shutter into an external wall than is the case with other roller shutter systems, while maintaining the airtightness of the building envelope and avoiding local cold bridges.

Particularly in prefabricated construction (prefabricated houses), it is also necessary to equip pre-assembled wall elements with a roller shutter box that is as completely pre-assembled as possible.

With regard to the roller shutter boxes currently in use, this presents the difficulty that, on the one hand, the wall element, including the roller shutter box, must be largely prefabricated, but, on the other hand, transport safety must be ensured. The wall elements are prefabricated in appropriate production facilities and also fitted with the roller shutter box and transported from the production facility to the construction site using suitable means of transport, usually by truck. Due to the considerable transport costs, it is important to make efficient use of the transport space, i.e. to ensure that the wall elements are packed as tightly as possible.

The roller shutter boxes prove to be a hindrance here, as due to their dimensions, part of the housing of these roller shutter boxes practically always protrudes considerably beyond the outer facade of the external wall. This not only leads to the problem of damage, but also means that significantly fewer wall elements can be transported to the building site per transport cycle and the available transport space cannot be used effectively.

The alternative of installing the roller shutter boxes on site has significant disadvantages, as the necessary specialist personnel are usually not available there.

is not available and the fundamental advantages of prefabricated construction or prefabricated parts, which consist in the efficient manufacture of wall structures using suitable resources under industrial conditions, can no longer be fully exploited.

The invention is therefore based on the object of improving a roller shutter box of the type mentioned at the outset in such a way that, while retaining the advantages of using pre-assembled units, which are particularly applicable to prefabricated construction, pre-assembled roller shutter boxes can be transported without damage and with efficient use of the transport volume and can be brought to full functionality at the place of use in an uncomplicated manner.

According to a first aspect of the present invention, this object is achieved with a roller shutter box of the type mentioned at the outset in that the housing of the roller shutter box is designed in several parts and the housing parts can be detachably connected to one another.

According to a second aspect of the present invention, the above-mentioned object is achieved in a roller shutter box of the type mentioned at the outset in that the drive and bearing device is displaceable within the housing, in particular displaceable in a straight line or pivotable about an axis of rotation.

Preferred embodiments of the subject matter of the invention are set out in subclaims.

The solution according to the invention makes it possible in a particularly simple manner to design a part of the roller shutter box that protrudes over an associated wall element so that it can be separated from the rest of the housing, so that this housing part is delivered separately to the construction site and/or the drive and bearing units

direction in which the roller shutter or another e.g. textile shading element (awning) can be wound up, to be accommodated displaceably within the housing of the roller shutter box, in particular between a rearward transport position (in the clear width of the wall element) and a forward working position located at least partially outside the clear width of the wall element, in particular either to be displaced in a straight line or to be pivoted about a horizontal axis of rotation.

Locking and latching elements, particularly in conjunction with the side head parts of the roller shutter box housing, serve to releasably fix the drive and storage device in the (extended) working position or the (retracted) transport position.

The partially removable housing (i.e. the housing part that extends beyond the clear width of the wall element) can preferably be separated from the rest of the housing along a vertical separation plane and screwed to it or connected to it in another detachable manner. In this case, locking or snap connections can also be selected, at least as a supporting measure to a screw connection, or an eccentric connection.

In the sense of the present invention, the term roller shutter box or the term "roller shutter" is understood not only to mean a device that actually contains a roller shutter consisting of roller shutter slats, but also a device that contains a textile shading device for windows or doors, such as an awning, which can be wound up on a rotating shaft or unwound from it.

The invention is explained in more detail below using exemplary embodiments and the associated drawings. In these:

Fig. 1 is a vertical section of an assembled front roller box for the

Prefabricated building in connection with a wall element in the area of a window in schematic representation,

Fig. 2 shows a coaxial horizontal section in the horizontal plane of a drive and bearing device of a roller shutter of the roller shutter box according to Fig. 1,

Fig. 3 is a view similar to that of Fig. 1, wherein the drive and bearing device for the roller shutter box is shown in a dash-dotted working position and a solid-line (pivoted) transport position within a clear width of an associated wall element,

Fig. 4 is a view similar to that of Fig. 3, but for an alternative embodiment of the roller shutter box, in which the drive and bearing device of the roller shutter is shown in a straight line (linear) between a working position shown in broken lines and a transport position shown in solid lines (receiving within the clear width of the wall element),

Fig. 5 is a representation of a roller shutter box similar to that in Fig. 1, but for a different housing geometry of the roller shutter box housing,

Fig. 6 is a schematic representation similar to that in Fig. 3, but with an outer housing part removed from the rest of the housing of the roller shutter box, and

Fig. 7 is a schematic representation similar to that in Fig. 1 when installing the roller shutter box in a prefabricated wall with thermal insulation composite systems.

· · ■

Fig. 1 shows in vertical longitudinal section the basic structure of an inventive roller shutter box 1 with guide rails 2 for the roller shutter 3 shown in a dash-dotted outline, inserted into a pre-assembled prefabricated wall element 4 with window frame construction 5, window sash 6 and a roller shutter operating device (here crank) 7. A drive and bearing device with roller shutter shaft within the roller shutter box 1 is designated with 8.

The roller shutter box 1 has a housing 10 which is divided along a vertical dividing plane 10a, wherein a housing part 10b protruding beyond the wall elements is integrally removable from the remaining stationary housing part 10c.

A screw connection of the housing part with the rest of the housing, only indicated schematically here, takes place at 11 (top) and 12 (bottom), whereby the upper screw connection 11 takes place in particular with an angle element 13, only indicated schematically here, spanning the respective lateral head parts 10d of the roller shutter box at both ends.

Fig. 2 shows, in a horizontal section through the roller shutter winding shaft 9, the structure of the wall element 4 or the installation of the roller shutter box 1 in a wall element 4 in the area of a window 5, 6. With the help of an angle element 13 (above) only indicated schematically here, the front housing part 10b (removable) is screwed to the remaining housing part 10c at the screw connections 11, 12.

However, the further means or mechanisms for moving the roller shutter winding shaft 9 or the drive and bearing device 8 for the roller shutter 3 are not shown here, so reference is made to the following explanations based on the other figures.

At 8 is the drive of the roller shutter shaft 9, which is mounted opposite in a bearing 14.

Referring to Fig. 3, this figure clearly shows the projection of the roller shutter box 1 over the outer wall (in the direction of the arrow) - wall element 4 -, whereby in this illustration not only the screw connections 11, 12 for removing the protruding housing part 10b of the housing 10 of the roller shutter box 1 along the vertical division plane 10a, but also the displacement of the drive and bearing device 8 for the roller shutter 3 by pivoting about a horizontal pivot shaft 15 is shown schematically, so that in a transport position (solid lines) the roller shutter bearing and actuating device comes to lie within a clear width of the wall element 4 and the outer housing part 10 can be removed from the remaining housing part 10c along the vertical division plane 10a.

The drive and bearing device for the roller shutter pivots inwards after releasing a locking bolt (not shown here) (preferably spring-loaded) and can be locked in this position. The working position of the drive and bearing device 8 with the locking position 16 is shown in broken lines.

The outer housing part 10b, shaped as a round box, can be removed in its entirety after loosening the screw connections 11, 12, as shown in Fig. 6. Fig. 3 shows in solid lines the roller shutter drive and storage device 8 in its (swung back) transport position. In this state, the roller shutter 3 (not shown here) is accommodated within the guide rails 2 (covering the window), i.e. unwound from the roller shutter winding shaft 9.

Fig. 4 shows an alternative embodiment, wherein the same reference numerals designate the same elements as in the previous embodiments.

Here, the roller shutter drive and storage device 8 is moved parallel and straight inwards along a sliding guide rail arrangement (not shown) between a working position shown in broken lines and a retracted transport position (shown in solid lines) and is locked in each of these positions.

Fig. 5 shows a further embodiment of the invention, in which a split roller shutter box is also used and the drive and bearing device for the roller shutter can be displaced inwards (without this being shown here), whereby the housing shape of the roller shutter box as a round box differs from the other embodiments.

Fig. 6 illustrates the transport state of the wall element 4 with the roller shutter box inserted (stationary housing part 10c) and the drive and bearing device 8 for the roller shutter displaced in the transport position. The outer housing part 10b is removed. If necessary, the resulting front opening along the dividing plane 10a of the front roller shutter box can be closed by a closure element.

Fig. 7 shows the roller shutter box according to the invention in connection with a wall element 4, which at the same time carries a thermal insulation 17 (thermal composite system) on which a plaster layer 18 is located.

The invention makes it possible to realize an efficient use of the transport space for fully assembled roller shutter boxes with a high level of transport safety, whereby the roller shutter box can be moved to its working position on the construction site by returning the roller shutter drive and bearing device (roller shutter shaft).
