f Consists of a plurality of interconnected slats

existing roller shutters

I The present invention relates to a roller shutter consisting of a plurality of interconnected slats according to the preamble of claim 1.

In the known suspension devices, the tab in the connection area with the receiving profile (aluminium or plastic) is guided through a slot, bent over and connected to the long side of the tab, so that a hinge-like joint is created.

Both in terms of manufacturing and long-term resilience However, there are some significant disadvantages.

The manufacture of the suspension device is therefore quite complex, '■ because the tab is subsequently inserted into the finished mounting profile For this reason, the manufacturing costs are relatively high, which is particularly disadvantageous from the point of view of series production.

In particular, frequent raising and lowering of the roller shutter, as is usual, places particular stress on the support profile, the weak point of which is the connection area to the tab, so that the hinge pin, which functions as a hinge, often tears out.

Naturally, the subsequent necessary repair, i.e. replacing the entire suspension system, is very complex and costly.

The present invention is therefore based on the object of designing a roller shutter of the generic type in such a way that its suspension devices can be manufactured more easily and cost-effectively and that their service life, even under continuous use, is significantly increased.

This object is achieved by a roller shutter having the features of claim 1.

This structural design of the suspension device now makes it possible to incorporate the tab, together with the pin, as a part already mounted on the pin into the receiving profile in one operation, i.e. to cast it in.

Subsequent processing in the sense that the tab is only attached to the mounting profile after it has been manufactured is therefore not possible. no longer required, resulting in significant cost savings.

A further advantage resulting from the invention is the greater load capacity of the suspension device, since the metal pin, which is Casting is firmly anchored in the holding plate and can of course absorb forces that occur for longer than the previously provided plastic bridge, which functions in the same way.

In terms of load capacity, the number of self-service suspension devices can now be reduced, which also results in cost savings.

ALULUX W 3 -T

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

The only figure shows a suspension device in a front view.

The figure shows a suspension device, which is provided with the reference number 1 as a whole, which consists of a receiving profile 3 and a tab 4 which is articulatedly attached to it .

The plastic mounting profile 3 is positively attached to the last slat 2 of a roller shutter, whereby it is pushed over a bead 6 of the slat 2, which lies in a corresponding recess of the mounting profile 3.

With its end facing away from the receiving profile 3, the tab 4 is attached to a winding roller (not shown) which is mounted in a roller shutter box provided by the customer.

'

In the connection area with the tab 4, a metal pin 5 is cast into the receiving profile 3 , which runs parallel to the longitudinal axis of the slat 2. The metal pin is preferably made of rust-resistant steel.

I In this area the tab 4 is bent so that it covers the pin 5 ;

completely encloses and thus forms a hinge. \

The holding profile 3 has a recess 7 into which the tab 4 projects , enclosing the pin 5 which is arranged in the base area of this recess 7 .

Since the pin 5 is thereby close to the outer edge of the lamella 2 or the WuI- j

stes 6 vet runs, a favorable leverage effect results, which leads to a :

Claims (4)

ALULUX - 4 -; Protection claims 1. Roller shutter consisting of a plurality of interconnected slats, which can be suspended from a construction-side winding roller by means of suspension devices, each suspension device consisting of a Slat-mounted, made of plastic receiving profile and a flexible tab hinged thereto and connected to the winding roller, characterized in that a pin (5) preferably made of metal is cast into the receiving profile (3), which pin forms a hinge axis for the tab (4) mounted thereon forms. 2. Roller shutter according to claim 1, characterized in that the pin (5) is arranged parallel to the longitudinal axis of the slat (2). 3. Roller shutter according to claim 1, characterized in that the receiving profile (3) has a recess (7) in the base area of which the pin (5) runs, the latter being arranged immediately adjacent to the outer edge of the slat (2). 4. Roller shutter according to claim 1, characterized in that the pin (5) is made of rust-resistant steel.
