摘要： 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.

摘要： 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).
摘要翻译：提供了用于提升和倾斜威尼斯百叶窗的头轨硬件。单个控制器（5）同时控制升降和倾斜功能。多匝带制动倾斜器（19）与每根梯绳（15）一起使用，以减小在提升或降低百叶窗时遇到的摩擦力。每根梯绳的一端连接到其倾斜器的臂（21）上。倾斜器直接围绕没有中间部件的旋转驱动杆（11）设置，并且由如现有技术百叶窗中那样安装在头轨中而不是由驱动杆（11）支撑的支架（17）支撑。驱动杆（11）旋转倾斜器（19）和升降机构，直到倾斜器（19）接触止动件内置于每个支架（17）中。进一步的旋转使百叶窗完全倾斜，同时提升或降低百叶窗。在优选实施例中，升降绳索（13）连接到驱动杆（11）上，当杆（11）旋转以提升百叶窗时，驱动杆（11）横穿以将帘线（13）积聚成单层。杆（11）在倾斜器（19）内的旋转大大地降低了横穿杆（11）所需的横向力。提供了创新的轴承支撑件（41），使得百叶窗的重量从倾斜器（19）直接传递到支架（17），从而进一步减小横动杆（11）上的摩擦阻力。
