Abstract:
1. Apparatus for moving or rocking an infant enclosure of the type having at least three legs by which said enclosure is normally supported on an underlying surface, said apparatus comprising a plurality of support modules associated with respective said legs and positioned in use between said legs and said surface, each said support module having a socket or saddle for receiving the lower end of a leg of the enclosure, each support module including resilient support means providing independent and resilient support for each said leg, one of said support modules including a solenoid actuator for causing when actuated repeated resilient compression of said resilient support means of said one support module for imparting a substantially vertical oscillating or reciprocating motion to a first leg of said enclosure supported on said one support module, said solenoid actuator having an armature and a coil, said armature of said solenoid being rigidly connected to the socket or saddle and being oriented substantially vertically whereby current applied to said coil causes said coil to move substantially vertically along the armature and thereby cause compression of said resilient support means and the resilient support means of said other support modules causing movement of the other legs of said enclosure upon motion being imparted to said first leg of said enclosure by said solenoid actuator of said one support module to continue motion of said enclosure, and means for selectively actuating said solenoid actuator.
