CZ12595A3 - Louvre roller blind - Google Patents

Abstract

The louvre-type roller shutter has at least one pull chain, whose links (2) are hinged together and connected with tiltable, lamella-like slats (1), and at least one adjustment chain, whose links (5) are hinged together and connected with the slats (1). The adjustment chain links (5) overlap the pull chain links (2), and preferably the slats (1) also at least partially overlap the pull chain links (2). As a result, there are no cracks in the shutter, the shutter has a very compact design and the slats show a uniform cross-section throughout.

Description

However, the invention relates, for example, to shafts with a circular circumference, which are mounted eccentrically.

In summary, the invention may be presented, for example, as follows; ·

The roller shutter, which can be opened, has at least one traction chain, the chain links 2 of which are articulated to each other and to the rotatable lamella louver bars and at least one adjusting chain whose chain links 5 are articulated to each other and to the louver bars. The adjusting chain links 5 ' are drawn by the chain links 2 and preferably also cover at least partially the louver bars 1 - the chain links.

5.. . · \. .

This avoids gaps passing through the roller shutter, the roller shutter is made very compact and the roller bars have a constant cross-section.
