Abstract: An inventive friction hinge (5) is provided which also provides detenting in a position or arcuate range. The friction torque is provided by a spring band (13, 65 or 73) which fits tightly about a shaft (11, 61 or 67) or within the cavity of a housing. Detenting is provided by features (21, 63 or 71) on the band and the mating part (19, 59 or 69) that cause the band to change shape when the features align. The detenting torque can be varied by changing the detailed shape of the features. Covers (3) that close, as on laptop computers, can be held shut by the use of the inventive detenting friction hinge which can also provide the friction needed to hold the screen of the computer in position during operation.

Abstract: 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.

Abstract: There is disclosed a hinge assembly that has a pintle (9) and two plates that can rotate about the axis of the pintle. The first plate (17) is irrotatably affixed to the pintle. The second plate is part of a friction element which also includes a band having a plurality of turns helically disposed about the pintle. Between the other end (15) of the band and the second plate there is a spring (13) that tightens the band about the pintle. The band is flexible enough so that it does not grip the pintle without the force of the spring. Frictional force is developed between the band and the pintle that opposes movement of the second plate in a direction that tends to tighten the band about the pintle. Movement of the second plate in the opposite direction tends to loosen the band's grip on the pintle so that very little frictional force is developed.

Abstract: 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.

Abstract: There is disclosed a friction hinge assembly capable of providing hinged motion of two elements (1, 3) with a programmable frictional torque. The frictional torque can be made to vary with the angular orientation of the two hinged elements. The frictional hinge assembly is comprised of a band (17) wrapped around a pintle (5) which is constrained to move rotationally with the first hinged element. One end of the band has a lug (19) configured to press against the second hinged element, exerting thereupon a torque about the pintle. The other end of the band has a tail (25) to which is applied a controlled force to produce the desired frictional torque between the band and the pintle.

Abstract: A spring clutch assembly with reduced radial bearing forces is described. The clutch includes a shaft (43), at least first (49) and second (51) helically wound axially mounted springs for making frictional contact with the shaft (43), and engaging means (53, 55) corresponding to each of the first (49) and second (51) springs for selectively applying a tightening force to one end of each of the springs (49, 51) in order to prevent rotation with respect to the shaft (43). Each of the engaging means (53, 55) is radially and symmetrically disposed along the shaft (43) for eliminating radial bearing forces induced by the spring ends (57, 59, 61, 63).

Abstract: A spring clutch for limiting lost motion during release is provided. The spring clutch includes a shaft (29), a helically wound coaxially mounted spring (31) for making frictional contact with the shaft (29), and means (33), such as a tang element, for selectively applying a loosing force to at least one end of the spring (33) for rotation thereof with respect to the shaft (29). The inventive spring clutch further includes means (39) for urging the spring (31) toward the shaft (29) when the spring (31) is rotatably loosened. As a result, radial movement of the spring (31) away from the shaft (29) is substantially prevented. The urging means (39) may be retained by a housing (35) coaxially mounted about the shaft (29) and may be chosen from a boss (27) or an auxiliary spring (39). Preferably, the urging means is located at about 90 degress along the outer radial surface of the shaft from the end of the spring at which the tang element (33) is located. In another embodiment, a core is coaxially mounted within the shaft such that the spring is located between the shaft and the core and the urging means is retained by the core.

Abstract: A bi-directional spring clutch (11, 13, 15, 17) further including a ratchet (43) and pawl (23) so as to permit substantial torque to be transmitted to the shade roller only in one direction. In the other direction, the roller is nearly free to rotate so that the weight of the shade material depending from one side of the roller exerts a torque on the roller which prevents reverse rolling.

Abstract: An inventive friction hinge is disclosed that uses two or more bands (3, 13) each operating in their loosening mode of operation. The loosening mode is used to take advantage of the more reliable frictional characteristics that it provides. Each band wraps nearly around the hinge pin (7). Any number of bands can be used in each direction to obtain the desired torque characteristics. The novel friction hinge exhibits no lost motion and very slight spring-back.

Abstract: Headrail hardware to lift and tilt a Venetian blind is provided. A single control (5) operates both the lift and the tilt function. A multiturn band brake tilter (19) is used with each ladder cord (15) in a way that reduces the frictional forces encountered in lifting or lowering the blind. One end of each of the ladder cords is attached to an arm (21) of its tilter. The tilters are disposed directly about the rotating drive rod (11) with no intermediate parts, and are supported by cradles (17) that mount in the headrail rather than by the drive rod (11) as in prior art blinds. The drive rod (11) rotates the tilters (19) and the lifting mechanism until the tilters (19) contact stops built into each of the cradles (17). Further rotation keeps the blind fully tilted while lifting or lowering of the blind continues. In the preferred embodiment, the lift cords (13) are attached to the drive rod (11), which traverses to accumulate the cords (13) in a single layer as the rod (11) is rotated to lift the blind. The rotation of the rod (11) within the tilters (19) greatly reduces the lateral force needed to traverse the rod (11). An innovative bearing support (41) is provided so that the weight of the blind is transferred from the tilter (19) directly to the cradle (17), further reducing the frictional drag on the traversing rod (11).
