DESCRIPTION

rolling gate

The invention relates to a roller door or a roller shutter with bars running in lateral guide rails, forming a curtain, which can be wound up or unwound via a rotatable shaft, the shaft being mounted at its ends so as to be horizontally displaceable.

Such roller doors or roller shutters are well known. In order to enable the curtain to enter the inlet funnel arranged above the side rails at least approximately vertically when it is unwound, the shaft must be able to move horizontally towards the rails during unwinding. Conversely, it moves away from the rails when the curtain is wound up. This movement is made possible by the horizontal displacement of the shaft bearing.

According to the current state of the art, this horizontal displacement is achieved by a roller bearing on the shaft of the roller door or roller shutter. The bearing plates, in which the shaft ends are arranged to rotate, are attached to carrier plates which have rollers that are guided in rails. However, this entails relatively high manufacturing costs and considerable assembly work. In addition, the structural unit designed in this way takes up practically all of the available space in the cover cap, so that the attachment of further units, e.g. limit switches, is hardly possible.

The object of the invention is therefore to create a roller door or a roller shutter according to the generic term which can be produced more cost-effectively and is easier to install.

This object is achieved according to the invention in that the bearings of the shaft can be moved horizontally via sliding guides.

In the context of the invention, it has surprisingly been found that the horizontal displacement of the shaft of the roller door or roller shutter can be achieved more cost-effectively using sliding guides. Contrary to the prejudices of experts, a sliding guide can absorb the forces of the shaft that occur in a roller door or roller shutter without jamming and this at a lower cost for the guide than with the known roller guides. In addition, the installation of the sliding guide is easier than that of the roller guide and the sliding guide takes up less space on the cover cap, so that additional units can be accommodated without any problem.

A further development of the invention consists in that the bearings of the shaft are arranged on bearing plates, which in turn are fastened to the support plates of the sliding guides.

Within the scope of the invention it is further provided that the sliding guides are attached to the cover caps of the roller door or roller shutter.

Finally, a development of the invention consists in that the sliding guides rise away from the guide rails at an angle ω of to .

An embodiment of the invention is described below with reference to drawings.

Show it

Fig. 1 shows a cover cap with a guide for the shaft according to the invention

Start of the winding movement in plan view,

Fig. 2 the arrangement according to Fig. 1 towards the end of the winding movement,

Fig. 3 is a side view of Figs. 1 and 2,

Fig. 4 shows a detailed view of the shaft guide.

As can be seen from Fig. 1 to 3, a curtain 1 of a roller door or a roller shutter consisting of bars is attached to a shaft 2 and wound up or unwound by rotating the shaft 2. The curtain 1 enters the guide rails 4 via an inlet funnel 3. Since at the beginning of the winding movement (Fig. 1) there are still few bars on the shaft 2, the shaft must be arranged relatively close to the guides in order to ensure that the curtain 1 enters the guides 4 at least approximately vertically.

However, since this position would only allow a small number of bars to be accommodated on the shaft 2, the shaft 2 moves away from the guide rails 4 in a substantially horizontal plane during the winding movement (Fig. 2).

This is made possible according to the invention by essentially horizontally arranged sliding guides 5 on which the bearings of the shaft 2 are arranged. It is expedient for the sliding guides 5 to rise away from the guide rails 4 at an angle ω of 1 to 10°.

The sliding guides 5 are fastened to the cover caps 6 and have a carrier plate 7, on which in turn the bearing plate 8 is fastened, which carries the bearing of the shaft 2.

The structure of the sliding guides 5 can be seen in detail in Fig. 4. A sliding element 10 with a friction-reducing coating 11 on both sides is enclosed by a smooth, clamp-shaped plate 9, so that it can only move in the longitudinal direction of the plate 9. The sliding element 10 has a carrier plate 7, on which the bearing plate 8 is arranged in the present example.

Claims (4)

1. Roller door or roller shutter with bars running in lateral guides, forming a curtain, which can be wound up or unwound via a rotatable shaft, the shaft being mounted at its ends so as to be horizontally displaceable, characterized in that the bearings of the shaft ( 2 ) are horizontally displaceable via sliding guides ( 5 ). 2. Roller door or roller shutter according to claim 1, characterized in that the bearings of the shaft ( 2 ) are arranged on bearing plates ( 7 ), which in turn are fastened to the support plates ( 6 ) of the sliding guides ( 5 ). 3.
