Wind-up technique for mechanical clock mechanism enabling significant extension of the wind-up period

摘要

The technique involves the spring force of the spring in the spring housing (5) being applied to the conventional clock mechanism and to a spiral (1) arranged around the clock mechanism. The spiral runs a gear wheel (6) connected to the conventional toothed spring housing and unloads itself when sufficient pressure is exerted by the spring and simultaneously rewinds up the conventional spring as well as possible.
