摘要： Disclosed is a spring motor and control for use especially with window blinds. The motor comprises a storage drum having a first axis, an output drum mounted for rotation about a second axis parallel to and spaced from the first axis. A spring member is connected to and between the storage drum and the output drum to form a spring motor. The spring motor has laterally extending, spaced apart drum supports on opposite sides of the drums to support them for rotation. A coupled drive is connected to the storage and output drum whereby rotation of one of the drums in a first direction about its axis effects rotation of the other of the drums about its axis and in an opposite direction to cause winding and unwinding of the spring member between the drums. A drive actuator is connected to the coupled drive to effect rotation of the drums, and an adjustable friction member is engageable with one of the coupled drive and the drive actuator to adjustably alter the force necessary to effect movement of the coupled drive.

摘要： A cordless, balanced Venetian blind or shade with a a spring motor includes conventional window covering components without the outside hanging lifting cords or cord locking mechanisms. one or more spring motors are employed. A cord spool, in the preferred embodiment, is coupled to one of the spring drums to serve to wind the cords to cause the blind to be raised or lowered, simply by manipulation of the bottom bar of the blind system. Due to the spring forces, the system compensates for the increasing weight on the cords as the window covering is raised and for the decreasing weight as it is lowered.

摘要： A cord lock for a venetian blind or shade, such as a pleated shade, having a housing with a stationary pulley and a serrated cam or rivet guided in parallel, aligned S-shaped slots, the cam locking the raised lift cord of the blind or shade against the pulley. The S-shape of the slot maximizes the angle of approach of the slot with respect to the cord and pulley to thereby increase the sensitivity of the lock.

摘要： A system for adding weight to and/or balancing the bottom rail of a window covering includes one or more body members positioned within the bottom rail, and each body member having a plurality of sockets for receiving weights. In the most preferred form of the invention, the sockets are horse-shoe shaped and are adapted to receive elongate rods having a circular cross-section. The plurality of sockets in the most preferred embodiment include sockets located adjacent the front of the bottom rail when the body member is in place and other sockets arranged toward the rear. Weighting and balancing is achieved by placing one or more rods in selected ones of the sockets.

摘要： A cordless, balanced venetian blind or shade with a constant variable spring motor includes conventional window covering components without the outside hanging lifting cords or cord locking mechanisms. One or more constant variable force spring motors are employed, preferably comprising springs which vary in thickness or in width along their length as they are wound around storage drums. A cord spool, in the preferred embodiment, is coupled to one of the spring drums to serve to wind the cords to cause the blind to be raised or lowered, simply by manipulation of the bottom bar of the blind system. Due to the difference in thickness or width of the spring, the system compensates for the increasing weight on the cords as the window covering is raised and for the decreasing weight as it is lowered.
摘要翻译：具有恒定可变弹簧电机的无绳平衡的威尼斯盲帘或阴罩包括常规的窗户覆盖部件，而不需要外部悬吊提升绳索或绳索锁定机构。使用一个或多个恒定的可变力弹簧马达，优选地包括当它们缠绕在储存鼓上时沿它们的长度变化的弹簧的厚度或宽度。在优选实施例中，线轴被联接到弹簧鼓中的一个，以便简单地通过操纵盲系统的底部杆而使绳索卷绕以使帘子被升高或降低。由于弹簧的厚度或宽度的差异，当窗罩上升时，该系统会补偿帘线上的重量增加，并降低重量。
