发明名称 Spring counterbalance apparatus and method
摘要 A spring counterbalance apparatus and method consists of a shade system with a torque profile, where the shade system is connected with a drive shaft. A first spring system is connected with the drive shaft where the first spring system is a standard wound spring system. A second spring system is connected with the drive shaft where the second spring system is a reverse wound spring system and where, in combination, the first spring system and the second spring system produce a counterbalance torque profile approximately equal to the shade system torque profile.

主权项 1. A spring counterbalance apparatus comprising: a shade system with a torque profile, the shade system having-a drive shaft; a first spring system connected with the drive shaft wherein the first spring system is a standard wound spring system having a spring storage spool and a spring drive spool; a second spring system connected with the drive shaft wherein the second spring system is a reverse wound spring system having a spring storage spool and a spring drive spool; wherein in combination the first spring system and the second spring system produce a counterbalance torque profile approximately equal to the shade system torque profile; wherein an axis of rotation of the spring drive spool of the first spring system and an axis of rotation of the spring drive spool of the second spring system are aligned; and wherein an axis of rotation of the spring storage spool of the first spring system and an axis of rotation of the spring storage spool of the second spring system are aligned.
