Definitions

  • This invention relates to a retractable closure for a building opening, said closure comprising a flexible sheet having opposite first and second lateral edges and a third edge extending transverse to said first and second lateral edges, a retractor mechanism connected to the third edge, with the flexible sheet being capable of being extended over said building opening to an extended position in opposition to the retractor mechanism, while being retractable to a retracted position by the retractor mechanism, first and second guide tracks positioned to receive said first and second lateral edges respectively for movement therealong, and engagement members secured to at least one of said first and second lateral edges to keep said at least one lateral edge in engagement with the relevant one of said first and second guide tracks.
  • Such a closure is inter alia known from United States Patent 3,149,665, which describes a roller type screen with particular reference to an insect screen for window openings.
  • the insect screen according to US 3,149,665 is provided with a series of spaced engagement members on each side edge of the screen to restrain these side edges from being drawn out of their guide channels.
  • a retractable closure in accordance with the present invention is characterised in that said engagement members comprise pliable tongues biased to deflect from the flexible sheet in the extended position thereof and to be substantially flush with the flexible sheet in the retracted position thereof.
  • the structure according to the present invention securely holds the edges of the sheet of the closure to the respective guide tracks against the action of mere gusts of wind. Notwithstanding this more secure restraining of the sheet, it can still be disengaged from the guide tracks under excessive mechanical force without damage.
  • This kind of conditions may occur when persons accidentally walk through the closure if extended in a door opening or when playing children throw balls against the closure.
  • closure sheet can simply be put back in engagement with its side guidings whereupon the closure can be opened as before.
  • the flexible sheet can take a number of different forms, but the invention is particularly useful when the flexible sheet is a screen material, such as an insect screen.
  • both of said first and second lateral edges have engagement members secured thereto in the form of said pliable tongues.
  • the or each engagement member comprises a base portion and a flexible tongue attachment portion connected to said base portion and only said base portion is attached to said flexible sheet.
  • the retractor member may be a spring biased roller.
  • the guide tracks will be in the form of a channel, which may be partially closed by a flexible strip to prevent the ingress of dirt.
  • the engagement member(s) are adhered to the sheet by a hot-melt adhesive, which may be applied to the sheet for form a continuous tape rigidifying the edges of the sheet.
  • Figure 1 shows a retractable closure 1 mounted on a wall 3 in front of a building opening 5.
  • the closure essentially comprises a flexible sheet 7 which can be a decorative fabric material, a mere functional insect screen, an energy conservation shield or the like.
  • One vertical edge of the flexible sheet 7 is attached to a header bar 13 which is guided along the upper and lower guide tracks 9, 11.
  • the opposite vertical edge of the flexible sheet 7 is concealed within a vertical box 15 which houses a retractor mechanism, of conventional type such as a spring biased roller.
  • the retractor mechanism within box 15 either collects the flexible sheet material upon movement of the header bar 13 to an open position or pays out the sheet material upon movement of the header bar 13 to a closed position of the closure.
  • Figure 2 shows a portion of the bottom guide track 11 and a portion of the flexible sheet 7 guided therein.
  • the guide track 11 which is in the form of a guide channel has its upwardly directed opening partially closed off by a flexible guiding strip 17. To reduce friction on the flexible sheet 7 during opening and closing of the structure the flexible strip 17 preferably does not bear against the flexible sheet.
  • Figure 3 shows a cross-section of the structure of Figure 2 in which it can be seen that the lower edge of the flexible sheet 7 is provided with a pliable tongue 19.
  • the pliable tongue 19 has a free edge 21, also visible in Figure 2, which is deflected and spaced from the flexible sheet 7.
  • Figure 3 also shows that the flexible guiding strip 17 is engaged in a channel 23 provided for that purpose in the upper end of the guiding channel. If the flexible sheet 7 is subjected to minor forces such as gusts of wind then the pliable tongue 19 will be securely retained within the guide track 11 by the guiding strip 17. However, if forces are applied to the sheet 7 of a more excessive magnitude then the flexibility of the pliable tongue 19 and the flexible guiding strip 17 will allow the sheet 7 to escape from the guide track 11.
  • Figure 4 represents a partial cross-sectional perspective view of a lower guide channel.
  • the flexible sheet 7 in this embodiment is represented as an insect screen mesh. At the lower edge of this screen mesh is attached an engagement member in the form of a pliable tongue 19A.
  • Attachment of the engagement member to the lower screen edge can be by any suitable means, such as welding, gluing or by an overlying flexible adhesive tape.
  • an adhesive strip can be formed on the flexible sheet by a hot-melt adhesive deposition thereon.
  • Such hot-melt deposition can be brought into contact with the engagement members while being deposited thereon, or be remelted at a later stage to receive the engagement members.
  • the bottom guide track 11 is represented as a short section to allow the interior to be viewed. It should be understood that the guide track will in reality be much longer than the section illustrated in Figure 4. Similarly it should be understood that for simplicity the structure according to the present invention is described with respect to the lower guide track 11, but could be similarly provided on the upper track 9 or on both tracks at the same time.
  • the pliable tongue 19A is cutout from a base plate 25, which has a flat shape as illustrated in Figure 5.
  • the shape of the engagement member illustrated in Figure 5 can advantageously be obtained by die cutting of a suitable material such as polyester sheet material.
  • Hot-melt adhesive can advantageously be used in this manner as it loses its stickiness upon solidification.
  • the guiding strip 17A is formed as an integral extrusion having a mounting socket 29 which directly engages in the guide track 11 and a flexible flap portion 31.
  • the guiding strip 17A is suitably extruded from polycarbonate plastic.
  • One suitable type of adhesive is an acrylate type adhesive which may be applied to a tape 27 as shown in Figure 5.
  • the flexible sheet 7 is an insect screen mesh it may be necessary to place an additional tape or foil material on the opposite side of the mesh to prevent the adhesive from seeping through.
  • the tape 27 may alternatively be formed in situ on the flexible sheet material as a hot-melt adhesive deposition.
  • a substantial voluminous shape of the engagement members may be achieved when the flexible sheet is in a flattened and extended position.
  • the pliable tongues lie substantially flush with the surface of the rolled up sheet and do not significantly add to the thickness of the rolled layers.
  • plastic material for the pliable tongues and guiding strips may be used.
  • the materials mentioned hereinbefore are merely indicative of one suitable embodiment.
