Abstract
Abstract A display assembly is provided which most desirably comprises a lamp mobile having a base, a d.c. motor mounted within the base with a shaft extending outwardly from it, and the mobile mounted to the shaft. The interconnection between the mobile and the shaft can be a curved distal end of the shaft engaging an abutment surface of a similar radius of curvature formed within a body member of the mobile, with the shaft loosely received by the mobile, so that the mobile will rotate at a slower speed than the shaft. The base is screw-threaded onto the top of a cylindrical projection from a lamp harp, and a solar cell which powers the d.c. motor is also mounted to the lamp so that it receives light from the lamp light bulb. A pair of planar portions, one received by the lamp socket and the other mounting the solar cell, and interconnected by a hinge, may be utilized to properly position the cell to receive light from the lamp. The mobile includes a rod mounted at its central portion to the mobile body member, with a weight mounted to one end of the rod and a display item, such as an airplane model, mounted to the other end of the rod. Cooperating magnets disposed on the rod and base can cause the plane to move up and down as it rotates.
