Abstract
The invention concerns a clockwork motor, particularly but not exclusively, for toys, wherein an escapement consisting of a friction memeber that is pressed resiliently against a sliding surface moving with a part of the clockwork motor running down under the action of a mainspring, and wherein the pressure force for the friction member is arranged to be approximately proportional at any given moment to the driving force of the mainspring at the moment. The friction member is mounted on a carrier spaced from and movable relative to the sliding surface, and a stationary end of the mainspring engages with the carrier.
Claims8
Clockwork motor, particularly for toys, comprising a resilient member adapted to function as a mainspring, an escapement consisting of a friction member and a sliding surface, a carrier carrying the friction member and spaced from and movable relative to the sliding surface which in use moves with a part of the clockwork motor running down under the action of the resilient member, a stationary end of the resilient member that normally serves for support being in engagement with the carrier such that the friction member is pressed towards the sliding surface with a force that is approximately proportional at any given moment to the driving force of the resilient member at that moment.
