Description

Hollow body slats, preferably made of plastic, in particular for roller shutters,

The innovation relates to one preferably made of plastic Hollow body lamella, in particular for roller shutters, the interior space of which is parallel and spaced apart Walls are divided into several longitudinal spaces, hollow body slats of this type are known. Several such hollow body lamellas are if they are to form a roller shutter, connected to one another in such a way that they can be rolled up. Solehe hollow body lamellae can, however can also be used as a cover in the manner of strips, im. in the latter case they are attached to a frame provided with cross bars In both cases it is essential for the durability of these hollow body lamellas that they are exposed to pressure, the transverse to the first direction of the hollow body lamellae act and withstand bending loads, possibly also torsional loads.

Ba the previously known hollow body lamellae these stresses have not always grown, it is proposed according to the innovation to ensure that the transition between the hollow body and at least one of the walls is reinforced. Will the

Hollow body lamellas designed in this way then increase the production costs are practically hardly, but their durability is considerably increased.

The innovation is illustrated in two examples below schematically explained «

The hollow body lamella according to FIG. 1, which is part of a roller shutter

is, consists of the hollow body 1, which is divided into four rooms by three longitudinal walls 2,3,4. While the longitudinal walls 2 and 4 proceed as is known, the median longitudinal wall 3, a reinforcement 5 and 6, is forming, in the hollow body 1 via "This" is J stiffened this slat shutters for sufficient

In the case of the embodiment of FIG _e 2, which shows a cross section through a hollow body lamella, which can be used as a cover strip, the interior of the hollow body 7 by four longitudinal walls 8,9,10 and 11 is divided into five spaces. The longitudinal walls 8 and 11 go immediately, the longitudinal walls 9 and 10 respectively via a respective gain 12,13 '14,15 into the hollow body 7, the side walls 16 and 17 are so formed over _o In addition, that AuCl \ it gains 18.19 and 20.21 form respectively.
