Raising the bottom rail 16 may be effected by manipulating the operating cord 20, so as to wind the suspension cords connecting between the head rail 12 and the bottom rail 16. Lowering of the bottom rail 16 and closing of the window shade 14 may be done by manipulation of the operating cord 20 to unwind the suspension cords, and thereby lower the bottom rail 16.
  • suspension cords to raise the bottom rail to raise or lower the window shade is described in U.S. Patent No. 7,275,580 to Yu and U.S. Patent Publication No. 2008/00179017 to Yu et al. which are hereby incorporated by reference.
  • the window shade 14 may be of any type generally known in the art.
  • the window shade 14 may be a cloth material such as a honeycomb material, Venetian blinds, or any other type of shade known in the art.
  • the window shade 14 may include a plurality of rails or slats extending vertically and parallel to one another.
  • the head rail 12 may be of any types and shapes generally known in the art.
  • the head rail 12 may be located at a top portion of the window shade assembly 10 and configured to mount the drive axle 18 and control module 22.
  • the bottom rail 16 may be of any type generally known in the art and located at a bottom portion of the window shade assembly 10.
  • the bottom rail 16 may be raised by the operating cord 20 and the suspension cords (not shown) to move the window shade 14 in an upward direction.
  • the drive axle 18 may define a drive axis and be operatively connected to the bottom rail 16 such that rotation of the drive axle 18 will cause the bottom rail 16 to raise or lower. In one example, the rotation of the drive axle 18 causes the suspension cords to raise the bottom rail 16 and therefore raise the window shade 14.

  • the window shade assembly 10 may permit a user to raise and lower the window shade 14 by pulling on the operating cord 20.
  • the user may lower the window shade 14 by gently pulling the operating cord 20 in a downward direction.
  • the user may then release the operating cord 20, which will shift in an upward direction.
  • the upward shift of the operating cord 20, however, will not cause the window shade 14 to be raised or lowered. Instead, the window shade 14 will remain at a fixed and locked height.
  • the user may continuously pull the operating cord 20 in a downward direction to continue to raise the window shade 14.
  • a window shade assembly 10 may have a relatively shorter operating cord 20 that allows the user to raise the window shade by repeatedly pulling the operating cord 20 and then releasing the operating cord 20.
  • the operating cord 20 can be less than one half the height of the window shade. When the operating cord is one third the height of the window shade, the window shade is raised in three pulls of the cord. This process is similar to a ratcheting technique allowing the user to pull the operating cord 20 to raise the window shade 14 a certain amount, then allow the operating cord 20 to retract, and then pull the operating cord 20 again to continue to raise the window shade. This process may be repeated until the window shade 14 reaches a desired height. This configuration allows the operating cord to be a much shorter length than those traditionally used in the art.

While the drive axle 18 and adapter sleeve 76 rotate for lowering the bottom rail 16, the rolling member 50 rolls along the radial groove 78 and the guide track 64 of the clutch 30. More specifically, while the bottom rail 16 is lowered, the spring element 44 can exert resistance to keep the first and second coupling elements 40 and 42 stationary, such that the clutch 30 can remain in the uncoupled state without stop regions 61 in the guide track 64. In this uncoupled state, the radial rib 58 of the second coupling element 42 is spaced apart from the radial abutment 54 in the notch 65 of the first coupling element 40.

Abstract

L'invention porte sur un module de commande qui peut être utilisé pour relever et abaisser un store de fenêtre. Cette configuration permet à un utilisateur de tirer le cordon de manœuvre sur une distance prédéterminée pour relever le store de fenêtre, puis de relâcher le cordon de manœuvre jusqu'à ce qu'il soit rétracté, puis de tirer le cordon de manœuvre sur une autre distance prédéterminée pour relever de nouveau le store de fenêtre. Un mécanisme de freinage est relié fonctionnellement à un organe de desserrage de frein et conçu pour verrouiller ou déverrouiller l'axe d'entraînement. Un embrayage est adapté à être monté sur l'axe pour accoupler sélectivement le tambour de cordon avec l'axe. Le tambour de cordon peut tourner indépendamment de l'axe d'entraînement lorsqu'un embrayage est désaccouplé de l'axe d'entraînement. Le résultat est que le mouvement du cordon de manœuvre ne fera pas relever le store de fenêtre tant que l'embrayage est désaccouplé. Lorsque l'embrayage est accouplé à l'axe d'entraînement, le tambour de cordon et le manchon adaptateur peuvent tourner conjointement pour entraîner la rotation de l'axe d'entraînement pour relever le store de fenêtre.
