k. "Roller shutter box designed as a prefabricated part"

The innovation relates sl ** to a roller shutter box designed as a prefabricated part with a roll-up mechanism, which is housed inside the box and essentially consists of the bearings with bearing holders arranged on the front sides of the box, the roller that holds the roller shutter and the belt pulley for the one leading to the outside There is a tension belt. Roller shutter boxes of this type are known. They are included in the masonry above the windows or doors during the building of the house and later plastered in. For this purpose, the box walls are covered with lightweight panels or composite panels. The bottom of the box is usually closed by a wooden or metal strip after the window or door frame has been inserted.

The rotating parts of the roll-up mechanism are naturally subject to permanent wear, and this is particularly the case This is the case with the heavily used belt pulley and the tension belt itself. Carrying out any necessary repair work on the accessories of the inside the box However, due to the inaccessibility and confinement of the interior of the box, the roll-up mechanism poses a serious problem

after removing the wood or Metal strip on the underside of the box which then becomes free narrow gap offers only a spatially very limited intervention without any possibility of visibility. A proper one Repair, e.g. B. attaching a new tension belt to the belt pulley is in the known roller shutter boxes without structural Interventions not feasible.

The innovation is based on the task of designing a roller shutter box of the type described in such a way that assembly and Repair work on the built-in box without special precautions can be carried out conveniently.

This object is achieved according to the concept of innovation in that the side wall of the box facing the interior of the room at least in the area of the belt pulley one extends approximately over the

Has inze box height extending assembly and repair opening. In the case of particularly heavy or heavily used roll-up mechanisms, further openings in the area can be particularly susceptible to repair Accessory parts of the roll-up mechanism, for example in the area of the warehouse and / or in the case of motor-driven retractors be provided in the area of the engine. After another idea of innovation, the assembly and repair opening is covered by means of an easily detachable closure cover, which can optionally also be the carrier of the belt feed-through.

The lid, which is visible from the inside of the room, is preferably made of plastic or fine wood, so that

In addition to the useful effect, a decorative effect can also be achieved.

The drawing illustrates an embodiment of the innovation namely shows

1 shows a cross section through a built-in roller shutter box, while

¹¹ 2 shows the top view of the box from the interior of the room.

The roller shutter box 1 contains the belt pulley 2, the roller 5 and the outer bearings k and 5. The assembly and repair opening 6 is covered by the closure cover 7. The cover 7 carries the belt feed-through 9. The belt, not shown, runs through the slot 8 in the cover and the rollers 10 in the feed-through to the outside.

After loosening the fastening of the closure cover 7, it can be easily removed and the repair can be carried out. The inside of the box is illuminated by the light coming in from the room.
