Toy with swing

Claim 1

A toy that simulates a monkey swinging on a swing, comprising a suspension member, a perch member which is supported by said suspension member and which houses at least one battery cell, a toy monkey member having a tail which normally extends downward and which has an upper end and a lower tip end, said toy monkey member being mounted on said perch member and housing a driving mechanism electrically connectable to said cell and a swinging mechanism which is driven by said driving mechanism and whereby the perch member and the toy monkey member are caused to move alternately forward and backward, said toy being characterized by means for causing said tail to alternately curl up and extend when said driving mechanism is operating, comprising: an elongated tail frame within said tail that is resiliently flexible lengthwise, said tail frame having guide eyes at one lateral side thereof spaced at intervals along its length; a cord extending through said guide eyes and having one end secured to the tip end of the tail frame so that taking up the other end of the cord causes the tail frame to curl; a winding wheel adjacent to the upper end of the tail frame and to which said other end of the cord is eccentrically connected, said winding wheel being rotatable in a winding direction to take up the cord and being rotatable in the opposite direction by unwinding of the cord under uncurling bias of the tail frame; a driven gear concentric with said winding wheel and constrained to rotate therewith; a sector gear swingable about a sector gear axis and having gear teeth concentric to that axis which mesh with the teeth of the driven gear so that swinging of the sector gear in one direction imparts rotation in said winding direction to the winding wheel and rotation of the winding wheel in said opposite direction swings the sector gear in its opposite direction, said sector gear also having a cam follower surface extending substantially radially in relation to said axis; and a cam disc driven by said driving mechanism for unidirectional rotation about a cam disc axis which is in fixed spaced relation to said sector gear axis, said cam disc having thereon at least one substantially radially extending camming surface which engages said cam follower surface during one part of each revolution of the cam disc to swing said sector gear in said one direction, said cam disc being disengaged from said second gear during another part of the cam disc revolution to permit the winding wheel and the sector gear to move in their said opposite directions.
