Definitions

  • This invention relates to a shade construction and method for the manufacture thereof and more particularly to a shade construction which results in the cords and cord holes not being visible from the front of the shade and in enhanced durability and energy efficiency.
  • a piece of macerial is prepleated into a plurality of horizontal sections which stack one on top of the other when the shade is in its raised position. Alternate pleats face toward the front and rear of the shade. Each section has at least one hole punched through the center thereof which holes are aligned when the shade is folded. Normally, there would be two or- more aligned rows of holes formed in the shade sections. Cords passing through the aligned holes are utilized to control the raising and lowering of the shade.
  • the pleats have little structural rigidity and therefore tend to bow or buckle if there is a substantial width of pleat between cords. This necessitates using three or more cords for shades of moderate width in order for the shade to operate properly and to maintain acceptable aesthetic appearance.
  • This invention overcomes the problems and achieves the objectives indicated above by providing a shade which has a head rail, a botto rail, and a piece of material having a plurality of pleacs preformed therein, alternate pleats projecting towards the front and back of the material.
  • the material is connected at one end to the headrail and at the other end to the bottomrail.
  • a means is provided for securing together the two sections of material forming each of the back projecting pleats along substantially the entire width of the material to form a narrow tab projecting from the rear of each of such pleats.
  • the sections may be secured together by welding, gluing, sewing or other suitable means.
  • Cord holes are formed utilizing each of the tabs, corresponding holes being aligned, and a cord is provided which extends from the headrail through each aligned set of cord holes to the bottomrail.
  • the cord holes are formed in the tabs. At least .one of the cords is adapted, when operated, to control the raising and lowering of the shade.
  • the rigidity of the pleats may be substantially enhanced by providing a double-weld joint for the tab or by otherwise providing a multiple or continuous bond between the two fabric layers forming the tab.
  • joints used to form the tabs may be used as splice joints to secure together two pieces of material either for repair of a defective or damaged shade, to achieve a desired aesthetic effect, to customize the length of a shade, or for other purposes.
  • the energy efficiency of the shade may be enhanced by providing a metalized coating or layer for the rear surface of the shade.
  • the energy efficiency of the shade may be further enhanced by providing a second piece of material positioned behind the first. If the second piece of material has tabs formed in the same manner as the first piece, the pieces of material may ' e hung with the tabs facing each other and a means may be provided for maintaining a predetermined relative position between corresponding tabs of said pieces of material.
  • the tabs may be adjacent each other or may be offset by one pleat from each other and may be held in a desired relative position by having a single cord passing through corresponding cord holes in the tabs of both pieces of material.
  • the tabs When the tabs are adjacent, they may be held together either by butt welding, by being butted and secured to a common bridging piece of material or by being overlapped and glued, sewn, welded or otherwise secured together.

  • Each of the tabs 22 has at least one cord hole 26 formed therein. The exact number of.cord holes
  • cord 28 will vary with the width of the shade-and the rigidicy of the material, but most shades will have at least two cord holes.

  • Cord 28 passing through the center of profile 18 permits footrail 12 to hang straight when the shade is lowered.
  • cords 28 pass through cord holes 26 in tabs 22 rather than through the center of the sections in material 14, the cords are not visible from the front of the shade providing a pleasing visual appearance.
  • the absence of holes in the sections of material 14 also prevents light and air from passing chrough such holes and therefore enhances the insulating effect of the shade. This effect may be further enhanced by having a mecalized

  • Joints 24 and tabs 22 also significantly enhance the rigidity of the pleats, reducing the tendency of the pleats to bow or buckle between cords 28 and therefore reduce che number of cords which are required for a shade of a given width for the shade to operate properly and to achieve a desired aeschetic effect.
  • the memory strength and rigidity of pleats may be significantly enhanced by providing a multiple bond or a continuous bond between the fabric layers forming each tab. For example, a double-weld joint may be provided, as shown in Fig.

  • material 14 may be attached to rail 31 in the area 39 by glue or ocher suitable means.

  • a splice joint 24A might be used in a number of situations.
  • One situation would be where one or more sections of a large expensive shade have flaws or become damaged and it is desired to replace such sections without replacing the entire shade.
  • This embodiment of the invention would permit the flawed or damaged section or sections to be removed and either the remaining sections spliced together, resulting in a slightly shorter shade, or, when necessary, replacement sections being spliced in in place of the removed sections.
  • Another situation might be where it was necessary to splice together two pieces of standard-length material in order to achieve a custom shade of desired length.
  • a third situation might be where, to achieve a particular aesthetic effect or particular functional objective, two sections of different material are spliced together in a single shade.
  • the pieces of material spliced together might be of the same or different widths, density, color or pattern. The ability to achieve an invisible splice joint in a shade thus provides substantial flexibility in shade design.

  • Pleated pieces of material 14F and 14R are connecced in standard fashion to a headrail 10' and at the other end, to a bottomrail 12* having end caps 21. The exact manner in which the connections are made to headrail 10 1 and boccomrail 12' do not form part of the present invention.

  • corresponding tabs 22F and 22R are secured together by a piece of material 34 which spans the tabs over substantially the entire width of the shade but is not necessarily continuous and is secured to each of the tabs by being glued, sewn, welded or by ocher suitable attachment means.
  • Cords 28 pass either through holes formed in piece of material 34, or through spaces between the pieces of material where material 34 is not continuous, and between corresponding tabs 22F and 22R.

Abstract

Le store est constitué par un morceau de matériau plié (14) et comporte deux parties qui forment chaque pli faisant saillie vers l'arrière et qui sont fixées ensemble pour former une languette (22) faisant saillie vers l'arrière. Chaque languette (22) comporte des trous de cordon (26), percés à travers les languettes (22) selon les modes de réalisation préférés de l'invention. La rigidité des plis peut être sensiblement augmentée par des articulations de soudure doubles (24) dont sont pourvues les languettes (22), ou bien par fixation multiple ou continue entre les deux couches d'étoffe formant la languette (22). Une articulation (24) utilisée pour former une languette (22) peut également être utilisée comme articulation de ligature pour fixer ensemble deux pièces de matériau (14, 14'), soit pour réparer un store défectueux ou abîmé, pour obtenir une effet esthétique désiré, soit pour adapter la longueur du store en vue d'une utilisation particulière. Une seconde pièce de matériau (14R) peut avoir des languettes (22R) ayant une forme identique à celle de la première pièce, les pièces de matériau (14F, 14R) étant accrochées aux languettes (22F, 22R) se faisant face.
