Abstract
A toy adapted to crawl down a vertical surface has a frame carrying a shell at one end and a roller at the other. The roller has a corrugated surface of soft tacky material such that the roller will roll slowly down a vertical surface.
Claims25
A toy comprising a shell and at least one wheel having a circumferential surface and supported to rotate relative to the shell, and a plurality of lobes angularly spaced and circumferentially and circularly extending around the wheel and projecting axially therefrom, each of the lobes having an arcuate surface with a curvature noticeably greater than that of a national circle enclosing the lobes, each of the lobes being constituted of a body formed of resilient material and the surfaces of the lobes comprising a sticky material.
A toy comprising a frame, a roller mounted on the frame for rotation about an axis, and a shell mounted on the frame, the shell defining an opening at one side, the roller having a circumferential surface which is constituted of a plurality of lobes angularly spaced and circumferentially and circularly extending around the roller and projecting axially therefrom, each of the lobes having an arcuate surface with a curvature noticeably greater than that of a notional circle enclosing the lobes, each of the lobes being constituted of a body formed of resilient material and the surfaces of the lobes comprising a sticky material.
A toy comprising a frame having two arms connected between their ends by a cross-bar, a shell loosely mounted on first ends of the arms to one side of the cross-bar, a roller rotatably mounted on second ends of the arms on an opposite side of the cross-bar to said one side, said roller having a circumferential surface which is comprised of a plurality of lobes angularly spaced and circumferentially and circularly extending around the roller and projecting axially therefrom, each lobe being comprised of a cylindrically shaped section which is formed around an axis which axis extends substantially parallel to the axis of rotation associated with the roller, each of the lobes having an arcuate surface with a curvature noticeably greater than that of a notional circle enclosing the lobes, each of the lobes being constituted of a body formed of resilient material and the surfaces of the lobes comprising a sticky material.
A toy comprising a shell and at least one wheel having a circumferential surface supported to rotate relative to the shell, a circumferentially extending band of resilient and deformable material extending around the wheel, and a plurality of lobes projecting radially from the band and being formed integrally with and of the material of the band, each of the lobes having an arcuate surface with a curvature greater than that of a notional circle enclosing the lobes and the exterior surfaces of the lobes comprising a sticky material.
A toy comprising a shell and a roller mounted within the shell for rotation relative to the shell, the shell defining an opening through which a circumferential surface of the roller projects for contact with a supporting surface, the circumferential surface of the roller comprising a plurality of lobes, each of the lobes having an arcuate surface with a curvature noticeably greater than that of a notional circle enclosing the lobes, each of the lobes extending parallel to an axis of rotation associated with the roller, the lobes being formed of resilient, tacky material, the resilience and tackiness of the material being such that where upper and lower lobes of the circumferential surface are pressed against a vertical surface the upper lobe is slowly resiliently deformed and peeled from the surface by the weight of the shell and roller, the roller pivoting on the surface about the lower one of the lobes to bring a lobe beneath the lower one into sticking contact with the surface, said lower lobe being resiliently deformed as it contacts the surface.
