Abstract
A toy having a body and a downwardly-extending rear frame movably supported on the body with a spring on the frame to urge the body upwardly, an axle supported on the lower end of the frame and wheels attached to the axle. The axle has a one-way clutch attached to it and the clutch is connected to the body by a cord. As the body moves downwardly, stressing the spring, the clutch is free-wheeled in a first direction and, when the spring forces the body upward, the cord rotates the clutch rotating the axle and, with it the wheels.
Claims9
A toy comprising,
- a body,
- said body having a front end and a rear end,
- said rear end having a hollow therein,
- a U-shaped rear frame having two legs and a transverse member connecting said legs,
- said legs each having bearing means on the distal ends thereof,
- an axle extending transversely of said toy and rotatably received in said bearing means,
- two rear wheels,
- said rear wheels being supported on said axle on the ends thereof and pinned against rotation thereon,
- a one-way clutch,
- said one-way clutch having an outer member and an inner member,
- said inner member being fixed to said axle,
- and means to allow said outer member to rotate in one direction relative to said inner member but restrained against rotation relative to said inner member in the other direction,
- a drum surface on the outer periphery of said outer member,
- a cable wrapped around said drum surface and extending upwardly and fixed to said body,
- a return spring,
- said return spring having one end attached to a said bearing and the other end fixed to said outer clutch member, urging said outer clutch member to rotate in a direction to wrap said cable on said drum surface,
- a crank member in said hollow,
- one end of said crank member being fixed to said transverse member of said frame, the other end of said crank member extending upwardly, generally perpendicular to said legs,
- a tension spring,
- said tension spring being disposed in said hollow in said body and having one end fixed to said body and the other end connected to the distal end of said crank, whereby a load on said body causes said U-shaped frame to tend to rotate, exerting a tensile force on said spring and allowing said cable to wrap on said outer drum surface, said outer member of said one-way clutch,
- said tension spring urging said legs to move downwardly, lifting said body whereby said clutch and said inner member with it, rotate, said axle pinned thereto, whereby said wheels are rotated in a forward direction with each cycle of movement downward and upward of said body.

A toy comprising,
- a body,
- a frame extending downwardly from said body and movable upwardly and downwardly relative thereto,
- an axle rotatably supported on said frame,
- wheels on said axle,
- a one-way clutch on said axle,
- said clutch having an inner member fixed to said axle and an outer member freely rotatable in a first direction and having means to restrain said inner member and said outer member to rotate together in a second direction,
- a flexible member having a first end and a second end,
- said first end being fixed to said body and said second end being wrapped around said outer member,
- and resilient torsional means connected to said outer member urging said outer member to rotate in said first direction, whereby, as said body moves up and down, said one-way clutch rotates said axle, moving said wheels on the floor.
