Definitions

  • the present invention relates to a window covering that may be raised without the need to apply a force to either a control mechanism or the window covering itself as the window covering is opened.
  • the present invention relates to a window covering having a control mechanism configured to exert an upward force on the shade element and bottom rail that is of sufficient magnitude to raise the shade element and bottom rail without additional force being applied by the user during raising.
  • Window shades and coverings are found in many applications and used to regulate the amount of light entering a room, and to provide aesthetic appeal to a decor.
  • Such window shades and coverings take many forms, including roller shades, Roman shades, Venetian blinds, and cellular shades.
  • Conventional cellular or pleated shades utilize cord locks or a transmission mechanism to raise, lower and position the window covering in a desired position. With window coverings utilizing a cord lock, cords run up through the folded fabric, across the inside of a head rail and exit through a locking mechanism.
  • Other cellular shades include a transmission mechanism and a continuous loop cord that is pulled by a user to raise and lower the window shade.
  • Roman shades and Venetian blinds also tend to include raising cords that are secured to a lower bar or bottom rail.
  • Cords present the potential hazard of a child getting caught in or strangled by the exposed control cord.
  • Cords also tend to distract from the aesthetics of a window covering in that they extend along the face of the window covering and, when the window shade is opened, must either be wrapped on a hook or just left on the floor.
  • window coverings that utilize cord locks the cords also experience substantial wear due to friction against surfaces as a result of raising and lowering of the window covering.
  • roller shades which operate in the absence of a cord.
  • These roller shades include a wound torsion- spring retraction mechanism in combination with a clutch or locking mechanism mounted with a roller onto which the shade is rolled and collected.
  • a roller shade is pulled down by a user to a desired location, where it is locked in place by the clutch or locking mechanism.
  • the user typically pulls on a bottom rail of the shade, extending the shade sufficiently to disengage the internal clutch or locking mechanism within.
  • the clutch or locking mechanism is disengaged and the user releases the shade, the shade is retracted using the torsion-spring driven retraction mechanism.
  • roller shades are only operable with flat shade material which rolls up neatly into a confined location.
  • the mechanism utilized in such roller shades is not compatible with other window coverings, such as cellular shades, Venetian blinds, and Roman shades.
  • window coverings such as cellular shades, Venetian blinds, and Roman shades.
  • a similar lifting mechanism is typically unsuitable in cellular shades, Venetian blinds, and Roman shades.
  • the material of the shade element is typically gathered by raising a bottom member, such as a bottom rail, and increasing amounts of weight are gathered on the bottom member as the window covering is raised. The reason for this is that the shade material or shade element increasingly stacks on the bottom rail as the bottom rail rises, which increases the load on the lifting mechanism.
  • variable force springs have been used. Such variable force springs are substantially more complicated in use and manufacture. Therefore, there is a need for a window covering raising mechanism for window coverings such as Venetian blinds, cellular shades and Roman shades that is self-raising and overcomes the foregoing problems.
  • the window covering is a self-raising window covering that includes a head rail, a shade element, such as a cellular panel, blind slats, or Roman shade material, a bottom rail, at least one raising cord operatively connected at a first end to the bottom rail, and a control mechanism.
  • the head rail may define an elongated channel wherein the control mechanism is disposed therein.
  • the control mechanism includes a drive axle and a drive unit operatively connected with the drive axle.
  • the drive unit which may be a constant force spring, is adapted to provide a substantially constant rotational force on the drive axle.
  • At least one cord winding assembly is also provided in co-axial relation with the drive axle.
  • the number of cord winding assemblies will be the same as the number of raising cords.
  • one cord winding assembly may be adapted to operate with multiple cords.
  • the cord winding assembly includes at least one winding drum operatively connected to a second end of the raising cord and having a tapered portion.
  • the cord winding assembly also includes a rotatable positioning member for moving the cord winding assembly laterally along the drive axle upon rotation of the positioning member.
  • the positioning member is a threaded tubular member connected to the winding drum.
  • the cord winding assembly is adapted to translate the rotational force on the drive axle to a raising force on the raising cord, wherein the raising force is greater than a total downward force exerted by the shade element and bottom rail throughout the range of opening and closing.
  • the cord winding assembly is rotationally secured with the drive axle by a hub member adapted to engage the cord winding assembly and the drive axle.
  • the hub member may be in a sliding relationship with the tapered portion of the cord winding assembly.
  • a clutch member or locking member is also operatively connected with the axle and adapted to releasabiy lock the drive axle in a desired position.
  • the clutch member comprises a reciprocator disposed coaxially relative to the drive axle and movable between a released position and a locked position, and a spring member connected to the reciprocator and operable to either tighten or relax the hold of the reciprocator on the drive axle.
  • the reciprocator is configured to cause the spring member to tighten on the drive axle in the locked position for blocking a rotation of the drive axle against the rotational force applied by the drive unit, and cause the spring member to relax the drive axle in the released position to permit a rotation of the drive axle under the rotational force applied by the drive unit

Abstract

La présente invention concerne un store auto-relevable ainsi qu'un mécanisme de commande du store. Le store comprend, en particulier, une unité d'entraînement telle qu'un ressort à force constante, qui est adapté pour appliquer une force de rotation sensiblement constante sur l'axe d'entraînement. Un cordon d'enroulement est monté de manière coaxiale sur l'axe d'entraînement et comprend au moins un tambour d'enroulement relié de façon fonctionnelle à une deuxième extrémité du cordon élévateur et doté d'une partie resserrée, ainsi qu'un élément de positionnement rotatif destiné à déplacer le cordon d'enroulement le long de l'axe d'entraînement, lors de la rotation de l'élément de positionnement. Le cordon d'enroulement est adapté de manière à transformer la force de rotation de l'axe d'entraînement en une force de relevage sur le cordon de relevage, la force de relevage étant plus importante que la force de descente exercée par l'élément store et le rail inférieur tout au long du processus d'ouverture et de fermeture. Un élément d'embrayage ou élément de verrouillage est également relié à l'axe en mode opérationnel, et adapté de manière à verrouiller, de façon libérable, l'axe d'entraînement dans la position désirée.
