摘要:
A spring device includes an intermittent accumulator and kinetics release trigger that gradually winds up to accumulate energy as driven by manual or other random intermittent kinetics and drives an kinetics release control to trigger off the spring to release kinetics to drive a load once the kinetics to the spring is accumulated to a preset value.

A motor for controlling the elevating and lowering of a load comprises a storage drum, an output drum and a spring member operatively connected therebetween to provide a spring motor therewith, and a pair of cord drums aligned with and respectively adjacent the storage drum and the output drum. A gear train including an idler gear associated with the storage drum drivingly interengages the cord drums with the output drum, whereby the elevating and lowering of a load attached to the cords on the cord drums is balanced regardless of whether the elevating or lowering force is applied centrally between the points of attachment of the cords to the load.
摘要:
A spring shoe, and also in particular a spring, as well as a method of returning energy to a user, are provided. In one embodiment, a method and apparatus stores foot strike energy and releases it after a slight delay, when it will exert a force on the user which includes a forward component. This is accomplished in an embodiment by a spring in the sole which has a decreasing spring force, such that the force required to compress the sole decreases for all or part of the compression displacement as the spring is compressed.
