Shutters

The invention relates to a roller shutter made of individual slats with a curved profile, which in lateral Guide rails are guided, and in which each slat on its top one extends over its entire Length extending suspension and on its underside one extending over its entire length Has a recess for the suspension of an adjacent slat.

There are known shutters, which consist of several, one into the other suspended slats. The slats are preferably made from a plastic hollow profile, which is slightly curved for better rolling up of the roller shutter.

The known roller shutters have the disadvantage that they rattle in the wind when lowered. aside from that do they not offer sufficient protection against breaker, since the known embodiments can at least partially be pushed up from the outside.

De.? The invention is based on the object of a roller shutter to create that does not rattle as much as possible and cannot be pushed up from the outside.

° 5 The solution to this problem is the initially mentioned type obtained in that the suspension is hook-shaped in cross-section, with the bent end of the hanger facing the front the lamella is bent over; and that the front of the lamella at the lower end as a support for the suspension the adjacent lamella is bent inwards at an acute angle.

When the roller shutter is pulled up, the suspension, which is bent forward, engages the sloping lower one End of the front one. This moves the suspension towards the front of the roller shutter. But it will When the roller shutter is pushed up from below, the upper end of the front is supported on the bent-over one lower end of the slat above, causing the lower slat towards the rear of the roller shutter is moved. In this way, the individual slats jam in the side guide rails. This effect also occurs when the roller shutter is completely lowered, since the superimposed Slats are moved in the same way by their own weight.

The slats shifted in this way and thus jammed in the guide rails can no longer be moved by the wind. If the guide rail has roughened surfaces on the surfaces facing the slats, the roller shutter can no longer be pushed up unhindered.

The preferred embodiment provides so that inadmissible pushing up of the slats is reliably avoided the invention that both guide rails on the inside the surface facing the back of the lamellae each have a vertically left row of teeth; and

§ A particularly advantageous design results from this

I by that in each lamella at the lower end a

Over the entire length extending chamber 20 is provided, in which the recess is located below and the \ is delimited inwardly by an inclined partition.

This sloping partition is when you push up the

^ Slats touched by the suspension. The inclined separating

ϊ wall then causes the suspension and thus the

I 25 lamella located underneath towards the rear ver-I is pushed.

Preferably the partition is made so that the inclination of the partition wall extends parallel to the bent inwardly off the end ³⁰ of the front side. The bent end of the front side and the partition wall then jointly cause the lamella suspended in the chamber to be tilted towards the rear.

are marked in the other applications.

The invention is explained below with reference to the drawings explained in more detail. Show it;

Fig. 1 shows a part of the roller shutter according to the invention in drained state in profile and

2 shows a possible embodiment in a simplified manner ° sr position.

Fig. 1 shows the principle of how the individual slats of the roller shutter jam in the guide rail can,

The guide rail 1 is U-shaped and has on one of its two legs 2, 3 one after inwardly directed row of teeth 4. In the illustrated embodiment only some teeth 5 of the row of teeth 4 are shown. The row of teeth 4 is otherwise indicated by the broken line 6.

The lamellae 7 shown in profile support one another / whereby the upper end 8 of the lamellae 7 is displaced in the direction of the row of teeth 4, whereas the lower end 9 is displaced in the opposite direction. The slats 7 each have an edge 11 at their upper end 8 on the rear side IO, which in the state shown here engage in the row of teeth 4 - the roller shutter can therefore no longer be pushed up.

The slats 7 are displaced by the inclined surfaces of the slats at their lower end 9. For this purpose, the lamellas 7 are bent inward at the front in the region of their lower end 9 at an acute angle. The bent end 9 forms a

sloping surface, which si ^ h on the one below Supports the lamella and moves it in the direction of the row of teeth 4.

In addition, the suspension attached to the upper end 8 13, 14 can also be designed so that it is supported on the lamella located above. As can be seen from the drawing, the suspensions 13, 14 are supported on inclined partition walls 15, whereby the tilting of the individual lamellae 7 in the direction j row of teeth 4 is supported. j

The suspensions 13, 14 engage through recesses 16 in chambers 17, which extend over the entire length of the Slats 7 extend.

In Fig. 2 is a possible embodiment of the slats given in simplified form. The simplicity has been emphasized here on the individual struts of the hollow profile waived because of.

Fig. 2 shows the position of the slats 2O when pulling up of the roller shutter. The suspensions 21 engage at the bent ends 22 of the lamella located above. Since the bent ends 22 are formed correspondingly obliquely, the suspension 21 slides and thus, too the upper area of the lamella to the front in the position shown. The edges 23 snap out of the Row of teeth 4 out.

30th

The slats 20 are wider at the bottom than at the top.

This ensures that the edges 23 cannot engage in the row of teeth 4 when the roller shutter is pulled up.

V 0982

The lower end 24 of the back 25 is inwardly Widened towards chamber 26 - This makes the recess 27 a little narrower, so that the suspension 21 does not can slide out downwards.

In addition, the suspensions 21 can according to the The suspension 14 of FIG. 1 can be bent. The suspension 14 (Fig. 1) is when pulling up the lamella 7 above it towards the front pressed. This supports proper disengagement from the row of teeth 4.

It should also be pointed out that the individual lamellae 1, 20 have a larger radius of curvature on their front side than on their rear side. This measure is advantageous for proper rolling up of the slats.

The rows of teeth 4 provided in the lateral guide rails 1 can be molded onto the guide rail 1 be or consist of a plastic tape inserted into the guide rail 1.
