Definitions
- the invention relates to a cassette roller blind a weighting profile at the lower end of a curtain and a roller blind drive.
- Such a cassette roller blind is from DE 42 39 507 A1 known.
- This document describes alternately with a toothing in axial grooves on the outer circumference of a stationary anchored pin and in axial grooves on Inner circumference of a tubular, with the drive member in Attached direction of rotation of the detachable housing Friction disks caused by axial forces under axial Shift can be pressed against each other.
- the drive means to design the roller blind in such a way that Weight profile not after the blind is raised sags more.
- the invention solves this problem with a cassette roller blind with the features of claim 1.
- the spring Only towards the end of the winding movement of the curtain, the spring is effective so that it Coupling elements in the other stop position of the predetermined angle of rotation so that the Coupling elements still within the specified angle are rotatable relative to each other if that The weighting profile is already on the cassette profile.
- the embodiment shows a cassette roller blind in which a curtain 1, on its lower edge Weight profile 2 is attached within a Cassette profile 3 on a winding shaft 4 mounted therein can be wound up.
- a curtain 1, on its lower edge Weight profile 2 is attached within a Cassette profile 3 on a winding shaft 4 mounted therein can be wound up.
- Cassette roller blinds according to the invention differ from Spring blinds in that the winding of the curtain 1 the winding shaft 4 is done by driving forces and not by a tensioned when pulling down the curtain Torsion spring.
- the cone 7 On the cone 7 are second complementary ones functioning as brake disks Coupling elements 11 and 12 axially displaceable arranged, which alternately rotatably with the pin 7 and are rotatably connected to the tubular housing 8.
- the Package from the brake discs 11 and 12 is supported on one End against a fixed on the pin 7 Abutment 13 from.
- the end plate 14 on the opposite The end has an axial curve, the one with an axial curve an intermediate member 15 cooperates so that the package from the brake discs 11 and 12 when the Drive member 6 in the winding direction of the curtain 1 solved and at the beginning of a rotational movement in the opposite direction is pressed together by the axial curves.
- Third complementary Coupling elements are through one with the Housing 8 rotatably connected coupling element 16 and by a Sleeve 18 shaped.
- Coupling element 16 is in with an angle of rotation against a torsion spring 17 the sleeve 18 connected, but axially displaceable is rotatably connected to the winding shaft 4.
- Cone-like Radial projections of the sleeve 18 engage in profile grooves Stops 9 on the inner circumference of the tubular winding shaft 4 on.
- One end of the torsion spring 17 is on the Coupling element 16 and the other end of the torsion spring 17 fixed to the sleeve 18. The torsion spring 17 will when the drive member 6 rotates Winding direction of the curtain 1 tensioned.
- the Curtain weight overcomes the maximum spring tension, so that the tubular housing 8 and the tubular winding shaft 4 in one defined by the stops 9 and 10 Stop position.
- the torsion spring 17 At the top of the reeling movement of the curtain 1, the torsion spring 17 in the way effective that it rotates the winding shaft 4 leading, so that the drive member 6 can be rotated further, if the weighting bar already corresponds to that in FIG has shown position and against that Cassette profile 3 abuts, causing the further rotation the winding shaft 4 is blocked.
- To avoid a Overextension of the torsion spring 17 becomes the possibility of Continued rotation through the stops 9 and 10 between the Winding shaft 4 and the housing 8 limited.
