Definitions

  • the present invention relates generally to guided screen systems of the kind employing a screen with a zip-like retention device on each lateral side thereof, and particularly but not exclusively to a method of manufacturing a rail for guiding one lateral side of a screen with a zip-like retention device.
  • Each guided screen system comprises a roller blind and a pair of guide rails disposed on either side of an aperture to be screened.
  • the roller blind comprises a roller with a blind fabric wound therearound.
  • the blind fabric has flexible strips on its lateral sides which are trapped within, but free to slide along, a specially shaped groove or keyway in each of the rails. With such a configuration, the blind fabric is held laterally between the rails as it is deployed from the roller.
  • US 4638844 and GB 2235005 disclose early forms of such a screen system, with different brackets for loosely mounting the guide rail; and WO2009/098433 discloses a current form of such a screen system.
  • Each flexible strip typically is one half of a zipper, but could be manufactured by moulding a soft or semi-rigid high polymer such as hot-melt synthetic resin or rubber. The important point is that each flexible strip has or forms an enlarged head region (at least in use) which slides along the keyway, but resists being pulled transversely out of the keyway.
  • a flexible strip is hereinafter referred to as a zip-like retention device or simply "half zipper”
  • a roller blind with such flexible strips for engaging corresponding rails is hereinafter referred to as a zip- like guided screen, regardless of whether one half of a zipper is actually used.
  • the blind fabric and half zippers when winding the blind fabric onto its roller, there is a tendency for the half zippers to spiral with an axial spread, rather than in a single plane, which conflicts with the aim of retaining the blind fabric between the rails.
  • the blind fabric and half zipper spirals to one side, the blind fabric is tilted to that one side which may cause the weight bar on the bottom of the blind fabric (hem bar) to tilt meaning it is no longer level. If the spiral abuts an adjacent surface, the blind fabric may then start to spiral in the opposite direction, so tilting the blind fabric and hem bar in a counter direction. This cycle repeats until the blind is fully raised.
  • the blinds of such conventional zip-like guided screens also suffer from wrinkling at the edge, where the half zipper is welded/attached to the blind fabric.
  • This wrinkling is caused by the difference in blind build-up on the roller between the single thickness of the blind fabric (between the half zippers) and the greater thickness of the half zippers at the edges.
  • the differences in thickness cause stretching of the blind fabric at the edges which is seen as wrinkling when the blind is deployed.
  • there is a difference in blind build-up diameter between the blind fabric in the middle and the half zippers at the edge causing stress in the blind fabric when wound on the roller between the tight roll at the edges (because of the thickness of the half zippers) and the loose roll in the middle (between the between the half zippers).
  • Such stress may cause creasing in the blind fabric on the roller, particularly when relatively thin blind fabrics are used and with larger blinds.
  • relatively fine half zippers i.e. half zippers with teeth less than 1.5mm thick
  • relatively fine half zippers i.e. half zippers with teeth less than 1.5mm thick
  • the blind fabric to pull all too easily its relatively fine half zippers away from the rails. This tendency remains even when the keyway was lined with specially shaped inserts.
  • the relatively fine half zippers are considered to provide insufficient anchorage in their respective rail keyways.
  • EP2335956 discloses a screen with zip-like guiding and holding elements on each lateral side thereof for movement along respective slots formed in a pair of opposed guiding rails.
  • Each guiding rail comprises an outer part of aluminium and an inner part of extruded plastics material.
  • the outer part has a substantially "U”-shaped cross-section
  • the inner part has a substantially "C”-shaped cross-section.
  • the inner part is resiliently compressed and retained in the outer part to form a keyway with a narrow slot for engaging the zip-like guiding and holding elements.
  • the present applicant has sought to provide an improved method of manufacturing the rail in order to reduce the tendency for a screen with a zip-like retention device to pull out from its keyway.
  • a method of manufacturing a guide rail for a zip-like guided screen comprising: providing an elongate body including a pair of spaced-apart walls defining a channel therebetween, each wall having a flange projecting laterally into the channel to define a neck region of the channel; and plastically deforming the elongate body to reduce the neck region of the channel from a first width to a second width such that the channel defines a keyway for receiving a zip-like retention device, the keyway having a profile which is maintained on completion of the plastic deformation and configured to allow the zip-like retention device to slide in a first direction along the channel, and to resist movement in a second direction perpendicular to the first direction which would separate the zip-like retention device from the elongate body.
  • the first width may be at least 1.Omm, perhaps even about 2.0mm.
  • the second width may be less than 1.0mm, and may even be 0.8mm or less, such as 0.6mm. In this way, it is possible to manufacture commercially guide rails for use with relatively coarse half zippers and even relatively fine half zippers.
  • the elongate body may have a base portion supporting the pair of spaced-apart walls, the base portion having a line of weakness which defines a hinge region when deforming the elongate body to reduce the neck region of the channel from the first width to the second width.
  • the line of weakness may lie in a plane midway between the pair of spaced-apart walls. In this way, one part of the elongate body on one side of the line of weakness may rotate relative to another part of the elongate body on an opposite side of the line of weakness when deforming the elongate body. For example, one part may rotate relative to the other part through an angle of at least 10 degrees, perhaps even at least 15 degrees, for example about 20 degrees.
  • the amount of plastic deformation between successive elongate bodies may be varied so as to manufacture bodies having differing second widths.
  • the elongate body may be formed from a metal, such as aluminium.
  • the step of providing an elongate body may comprise the step of extruding the elongate body.
  • deforming the elongate body may comprise passing the elongate body through a roller jig, the roller jig having roller means to clamp a first part of the elongate body and at least one press roller to urge a second part of the elongate body against the first part when reducing the neck region of the channel from the first width to the second width.
  • the roller jig may further comprise a stop member for limiting position of the at least one press roller to control width reduction of the neck region.
  • the resulting guide rail may be used in a screen system, such as those disclosed in US
  • the present invention also extends to a method of fabricating a screen system, comprising: resiliently mounting in a support frame a guide rail manufactured in accordance with the first aspect of the present invention; and providing a roller blind comprising a roller with a blind fabric wound therearound, the blind fabric having a zip-like retention device on one lateral side thereof which is configured to slide along the channel in the guide rail in an axial direction and resist being pulled out of the channel in a direction transverse to the axial direction as the blind fabric is deployed from the roller.
  • Resiliently mounting the guide rail in the support frame helps to maintain tension in the blind fabric during deployment when the support frame is secured to a surface such as a wall surrounding a window or door.
  • Figure 1 shows a perspective view of an elongate body for use in the manufacture of a guide rail for a zip-like guided screen, in accordance with one embodiment of the present invention
  • Figure 2 is a cross-sectional view of the elongate body of Figure 1;
  • Figures 3 A and 3B show respectively perspective and cross-sectional views of the elongate body of Figure 1 once deformed into a one type of guide rail;

  • the elongate body 10 includes a pair of spaced-apart walls 12, 14 upstanding from a base portion 16.
  • the pair of spaced-apart walls 12, 14 (which are inclined away from each other, with the angular separation being about 20°) define therebetween an open channel 18.
  • Each wall 12,14 has a flange 20 projecting laterally into the channel 18 to define a neck region 22 which has an initial minimum width Wi of about 2.0mm.
  • the base portion 16 includes a groove 24 extending in a notional plane midway between the pair of spaced-apart side walls 12, 14.
  • the groove 24 provides a line of weakness in the base portion 16, defining a hinge region 26 adjacent the groove 24 in the base portion 16.
  • Such an elongate body 10 is readily formed in aluminium using a conventional extrusion process.
  • Figures 3 A, 3B, 4A and 4B show the elongate body 10 after it has been plastically deformed to narrow the width of the neck region 22 from the initial width Wi to a reduced width W 2 .
  • one part 30 of the elongate body 10 on one side of the hinge region 26 rotates permanently through an angle (a), which may for example be about 20°, relative to another part 32 of the elongate body 10 on the opposite side of the hinge region 26.
  • the walls 12, 14 define a keyway 40 for receiving a zip-like retention device, the keyway having a profile configured to allow the zip-like retention device to slide in a first direction Y along the channel 18, and to resist movement in a second direction Z perpendicular to the first direction which would separate the zip-like retention device from the elongate body 10.
  • the angle (a) that the one part 30 is rotated relative to the other part 32 is about 20°
  • the reduced width W 2 is about 0.6mm, which means the resulting keyway 40 is suitable for use with relatively fine half zippers (i.e. half zippers with teeth less than 1mm thick).
  • rails having differing neck widths can be produced from the same extrusion 10.
  • the angle (a) that the one part 30 is rotated relative to the other part 32 is about 18°, and the reduced width W 2 is about 0.8mm, which means the resulting keyway 40 is suitable for use with relatively coarse half zippers (i.e. half zippers with teeth at least 1mm thick.

  • the roller jig 50 comprises two sets of rollers 52,54 which are spaced apart and define a passageway therebetween. At least one set of the rollers 52,54 is actively rotated (e.g. by drive spindle 55) to drive the elongate body 10 through the roller jig 50, and at least one set of the rollers 52,54 is resiliently biased towards the other set to exert a clamping force therebetween.
  • the rollers 52,54 engage and support a portion of the elongate body 10 including the wall 12.
  • a set of press rollers 56 are urged against another portion of the elongate body including the wall 14 to deform the elongate body 10 in order to reduce the width of the neck region 22 of the channel 18.

  • An adjustable stop 60 is provided to limit the inclination of arm 58 relative to the sets of rollers 52,54, and hence control the extent of deformation in the elongate member 10. By changing the position of the adjustable stop 60, the roller jig 50 can be controlled so that the width W 2 of the neck region 22 is reduced to the required dimension.
  • the roller jig 50 is provided with interchangeable rollers 52, 54 to accommodate elongate bodies with different cross-sections.
