Description
Self-locking roller blind
The utility pattern is a self-locking roller blind designed to screen panes, in particular in roof windows and doors in residential rooms and offices against sunlight.
Roller blinds used to screen panes in windows and doors in residential rooms and offices are common and widely used. Well-known window roller blinds fixed indoors have, over the top edge of the window panel, a screw- or tap bolt-mounted coffer containing a fabric rolled over a winding roll and clamped at its bottom part with a batten for moving the blind up and down. The batten is mounted between guide bars fixed to the window frame and positioned on both longitudinal vertical elements of the window frame. Depending on the roller blind type, the mechanism for winding the blind on the winding roll located in the coffer was spring-, chain-actuated or electrical. Solutions of self-locking roller blinds known, e.g. the one presented in the Polish patent application No P-350294, have a positioning mechanism located in the bottom batten of the roller blind with two spring-loaded brake mechanisms located in the vertical U- section- or non-full circle-shaped guide bars. The brakes are combined with a pull rod equipped with an eccentric level located in the handle of the bottom batten and the movement of the lever overcomes the spring tension and releases the brakes. A second version of this mechanism is a solution in which toothed battens are mounted on vertical guide bars and toothed mechanism locked with a brake pull rod on the blind's bottom batten. Another solution for a mechanism used to position the roller blind is presented in the description of a Polish patent application No P-343608, in which the blind cloth has, in its bottom batten, an aperture through which, lines running down from the window or door opening are pulled. The lines tcross inside the blind's bottom batten so that the right upper corner of the opening is connected with its left down corner and vicc-vcrsti.
Hollow cylinder-shaped brakes fixed on the lines are located at the outlet of the hollow blind's bottom bntlcn. The brakes lock the other line inside the batten. In another solution patented under No P-345736, the blind cloth is positioned on the lines that cross inside the blind's bottom batten which contains a brake in the form of rolls through which the guide lines are pulled. Another solution described in the Polish patent application No P-337988 has a brake in the form of a clip through which blind's guide lines are interlaced. Solutions used to screen windows, in particular roof windows had a complex structure, wcie exposed tυ frequent ruptures υf the guide line, which luunpered their use and increased operating costs.
In order to eliminate these deficiencies, a self-locking roller blind was designed based on the utility pattern (particularly useful for roof windows).
The self-locking roller blind, particularly useful for roof windows and designed according to the utility pattern is seated in the inner part of the window, it is wound around and flexibly stretched on a roll fixed inside the window frame. The roller blind has two guide bars mounted on two parallel, longer window frames in which a horizontal bottom batten with a separate blind cloth is fixed. The roll with a common stretching mechanism and the blind cloth wound around it is rotalionally fixed in two corners fixed lυ the window frame to which two vertical guide bars and a horizontal casing connecting the two corners and both guide bars are attached. The horizontal bottom batten to which the blind cloth with a handle in the middle of its length is attached, is on both sides finished with brake blocks seated inside the guide bars and eccentrically locked on the flat bar oT these guide bars. The brake blocks seated at the end of the batten are, in the plane perpendicular to the batten, triangle-shaped with two pivots on its external surface. Close to the vertex of the triangle, there is a pivot with an oval cross section, whereas below there is a cylinder-shaped pivot. The distance between the pivots is slightly higher that the thickness of the flat bar of the vertical guide bar's cross section. The guide bars are connected by a horizontal casing with corners fixed to the window frame. The corners, on one side, are connected to the axle of the roll with the blind cloth. The comers are angle bars, the profiled blades (amis) of which with a width corresponding to the shape of the guide bar and casing profiles have various thickness, whereas the slant gap at the interface between the casing and guide bars is covered from the outside by an arrow-shaped cover plate (the heads of the arrow arc rounded). The casing that linksthc two guide bars has a cross-section in the form of
a flat bar with rolled up edges. The flat bar, on its concave side, has two perpendicular angle bars, the blades of which arc facing each other, One of lhe blades is located al the angle of the edge flexure, whereas the blades of the other one are located at two-thirds of the width of the casing. At the starting point of the bend of the other edge flexure there is a flat bar which is perpendicular to the casing's base. The vertical guide bars located alongside the vertical side window frames have a cross section in the shape of a flat bar with rolled up edges. The flat bar, on its concave side, at the flexure bend has a pcip.eudiculai ly positioned angle bar.
The solution as per the utility pattern presented is aesthetical, light and durable and the brake blocks make it possible to lift the roller blind to any window pane level and to lock it at the desired position without any additional operations.
The self-locking roller blind as per the utility pattern has been presented on figures: fig.l - view of the self-locking roller blind disassembled into parts, fig.2 - view of the location of the brake block, fig.3 - guide bar profile and fig.4 - casing profile.
The self-locking roller blind as per the utility pattern is designed to screen roof window panes against sunlight. The self-locking roller blind has a bearing-mounted roll I with a blind cloth 2 wound on it. The cloth is stretched in a standard way. The roll of the roller blind i is seated in the comers 3 that are fixed to the window frame and which connect two vertical guide bars 4 located alongside the longer sides of the window frame with the horizontal casing 5 which is located horizontally over the roll \ and which connects two guide bars 4. Symmetrically opposite, left- and right-hand side comers 3 are made as angle bars, the blades of which with the width corresponding to the shapes of profiles of the guide bar 4 and casing 5 are of different thickness, whereas the slant gap at the interface between the casing and the guide bar is covered from the outside with a cover plate. Blind cloth 2 is fixed separably with a batten 6 that, at its ends, has brake blocks 7 located on guide bars 4 and a handle 9 located at the half length of the batten 6. Brake blocks have, on its external surface, two pivots ϋ and J_2, that enclose the flat bar 8 of the guide bar creating tin eccentric lock, that is released by tt movement of the handle 9. Cross sections of the casing batten 5 and of the guide bars 4 are in the shape of a flat bar with rolled up edges and have, on their concave side, sections located perpendicularly to the flat bar. The cross section of the guide bar is an angle bar 8 that is enclosed by pivots ϋ or 12 of the brake blocks 7. The cross section of the casing 5 has
two perpendicularly located angle bars, the blades of which are facing each other and a flat bar that is located peφendicularly at the edge roll-up point. These profiles make it possible to fix the casing 5 and guide bars 4 to the comer 3 and ensure adequate rigidity of the casing 5 and guide bars .
