Abstract

 The object of the invention comprises a building partition movable screen roller (1) for screening material (2), with porous material (3) inside movable screen roller (1), and an movable screen with roller (1) and a method for inserting porous material into the roller according to claims 1-4, of the movable screen according to claims 5-8.

Description

[0001] The object of the invention is a building partition movable screen roller and an movable screen with an improved rigidity of the movable screen roller.

[0002] An invention where an movable screen roller is reinforced by inserting a reinforcement rod in it has been disclosed under WO2020089220A1. The reinforcement rod, in its original position in a roller, bends to such an extent, that when subjected to maximum tension it flexes into a position where the reinforcement rod axis overlaps the roller axis before the deformation.

[0003] The disclosed solution reinforces a large sized movable screen roller, however it also adds to its weight and complicates movable screen installation in a window. The movable screen roller structure presented below solves this problem.

[0004] The essence of the invention is a building partition movable screen roller according to claim 1, an movable screen with that roller and a method for inserting porous material into the roller. The building partition movable screen roller for winding the screening material comprises a porous material inside. The porous material at least partially fills the interior of the movable screen roller, wherein the filled interior space is essentially located in a central part of the movable screen roller. Preferably the porous material is an expanding foam with stiffening properties, such as polyurethane foam. It is inserted into the interior of the movable screen roller via at least one opening located in an movable screen roller wall, or via a through-opening with its centre running along the roller longitudinal axis. Once the porous material is inserted into the roller, it bonds with the roller inner surface, preferably by adhesion. The screening material of the movable screen comprises two lateral edges, one of which is attached to the roller, where it is preferably attached to a roller longitudinal coupling socket. The second lateral edge ends with a beam which travels in movable screen side guide rails, wherein the movable screen roller is in a cassette. Preferably the screening material comprises screening fabric or casing, which is operated manually or using a motor, preferably a tubular motor seated in the movable screen roller. The movable screen roller is open on both ends and constitue an entry openings. For an automatically controlled movable screen, the tubular motor is inserted into the roller through one of its entry openings, and includes a form-fitting coupling connected to the cassette side housing socket, and in the second entry opening there is an assembly sleeve, designed to be suspended in the roller cassette side housing. Preferably the assembly sleeve is a sliding sleeve with a bearing facilitating movable screen roller installation in a cassette, amongst others disclosed under invention P.436651. The movable screen also features two side guide rails in which the beam constituting an end of the screening material is fed. The side guide rails are designed for attachment on a window or window jamb and the movable screen cassette side housings are attached to the guide rails. The movable screen roller is retracted into the cassette housing cover, which is connected to the cassette side housings. The housing cover is connected preferably using screws and snap connections with the cassette side housings.

[0005] Flexing of the movable screen roller causes the screening material to be incorrectly wound onto the roller, which might result in the material creasing. Stiffening of the movable screen roller using a stiff and light material reinforces the movable screen roller without increasing its weight. Therefore, the movable screen roller according to the invention ensures correct operation of the movable screen for which it is designed.

[0007] The movable screen roller 1 is open on both ends. It features a longitudinal coupling socket 11 for screening material 2. The movable screen roller 1 interior features porous material in the form of expanding foam 3 inserted into roller 1 through opening 12 in the roller 1 wall. Fig. 3 depicts the movable screen with roller according to the invention, which also includes cassette 4 with the aforementioned roller 1 inside it. Cassette 4 is constructed out of two side housings 41 and central housing cover 42. Screening material 2 wound onto the roller 1 in its entirety is inside the cassette, covered by housing cover 42. The other end of screening material 2 ends with beam 5, fed along movable screen side guide rails 6. Screening material 2 is fed manually or automatically, in which case screening material 2 movement initiates tubular motor 7 inserted into movable screen roller 1 through one of its entry openings 13. Tubular motor 7 includes a form-fitting coupling connected to the cassette side housing 41 socket. In the movable screen roller 1 second entry opening there is sliding sleeve 8 with a bearing to be suspended together with roller 1 in cassette 4 side housing 41.
