    摘要： A spring clutch mechanism (5) for the operation of roller shades (1) and other rollable items. This clutch mechanism (5) is designed to release for raising the shade (1) so as to minimize effort. Whereas prior art clutch mechanisms for roller shades are intended not to slip, or to slip only to save themselves, in this case, lowering of the shade is accomplished by overriding the clutch, causing it to slip. The clutch (5) can be adapted easily to accommodate known shade (1) weights. The inventive design provides superior operating characteristics and, because the clutch (5) can be built with as few as two parts, much lower cost.

    摘要： A capstan (6) based system for pulling and accumulating the pull-cords (10) used to lift hanging window coverings (2) from their bottoms. A cylindrical capstan (6) is supported in bearings so that it is free to rotate and move axially. A splined connection to a holding device permits controlled rotation and locking of the capstan (6). Each of one or more cords (10) is attached to the capstan (6) by means of a clip (16) which can be easily positioned to adjust the position and length of its cord. As the capstan (6) is turned, the cords (10) wind onto the capstan (6) in a single layer due to the camming action of a specially configured camming surface (15). The capstan (6) begins to move laterally when sufficient friction has developed between the capstan (6) and the cord (10) which has been wound onto it. This provides space for the cord to wind onto the capstan (6) in a single layer. During unwinding of the cord (10), a guiding surface (12), over which the cord (10) moves, pulls the capstan (6) back toward its original position. The camming (15) and guiding surface (12) can be made symmetric so that bi-directional operation of the system is possible.

    摘要： There is disclosed a friction hinge assembly that can be inexpensively produced having a shaft and, in the simplest embodiment, one sheet metal part. In the preferred embodiment, the friction band (21) and the bracket (31) are one piece. In order to achieve the necessary alignment between the axis of the friction band and the axis of the shaft (17), the configuration of the mounting hole (23) for the shaft is elongated only along one axis. This provides clearance for necessary manufacturing tolerances without introducing additional backlash. In another embodiment, proper alignment is assured by slotted mounting holes (37) for mounting the friction bands to the bracket.
