Abstract: Skateboard designs including a hanger with a yoke with two arms, comprising a bumper which provides an increasing force as the wheel axles are pushed away from their resting position, and wide wheels with an asymmetrical and gradually tapering profile as the wheel extends outward from the midline of the board, for improved “surfing-like” maneuverability including an enhanced ability to “carve” like a snowboard.

Abstract: A trench wheel has a relatively thicker wheel center and gradually tapering side walls that produce a thinner wheel as distance from the hub increases. The wheel center is preferably fabricated from stamped metal into a hat or thimble shape, and has a skirt or brim attached thereto which assists with the retention of an elastomeric outer wheel to the wheel center. Special adapter plates are illustrated which, in combination with the wheel center, permits mounting to both front and rear axles of all popular all-terrain vehicles. A method of controlling water in a field using the trench wheels on a vehicle includes cultivating, planting, and traversing the field to displace earthen matter and thereby channel the field.

Abstract: A mechanic's creeper (10) includes a pad (12) supported between a plurality of side rails (14) by a plurality of crossbars (15). The side rails (14) are of tear-shaped cross section such that no sharp edges are provided adjacent to the pad (12) held between the side rails (14). The pad (12), side rails (14), and crossbars (15) are held off the ground by a plurality of caster assemblies (20). The caster assemblies (20) are connected only to the bottom surface (16) of the side rails (14) such that no protrusion is created on the top surface (17) of the side rails (14). Specifically, each of the caster assemblies (20) is connected to an associated side rail (14) by a rivet nut (54) that communicates only with the bottom surface (16) of side rail (14). The caster assemblies (20) further include rolling elements (24, 26) and bearing races (32, 34) that allow the caster assemblies (20) to rotate about the axis of a kingpin (42).

Abstract: The “ICE WHEELS” consists of a wheel assembly, which permits interchange with in-line skate wheels for use on ice that reduces weight and or the rolling resistance on ice while the wheel is perpendicular to the ice. The wheel consists of a lightweight hub, bearing accommodating counterbores and an outer ring containing multiple ice-engaging structures and relief grooves. The ice-engaging structures comprise of an outer circumferential contact means, inner circumferential contact means, a new medial circumferential contact means and multiple support surfaces. A new feature of this invention is the elimination of one or both of the inner circumferential contact means penetration into the ice while the wheel is perpendicular to the ice. This leaves either a flat support surface; a flat support surface with one inner circumferential contact means or two support surfaces with a medial circumferential contact means in between while the wheel is perpendicular to the ice.

Abstract: The “MODIFIED WHEELS FOR ICE” consists of a wheel assembly which permits interchange with in-line skate wheels for use on ice that minimizes damage from fractures in the ice, particularly when the wheel is at an angle from perpendicular to the ice while pushing off or turning. The wheel is consists of a lightweight hub, bearing accommodating counterbores and an outer ring containing multiple contact means. When the wheel is at an angle from perpendicular to the ice the outer circumferential contact means being smaller in diameter than the inner circumferential contact means allows both contact means to engage the ice. A new load bearing support surface is both adjacent to the inner and outer circumferential contact means and parallel to the ice when the wheel is at a predetermined angle from perpendicular to the ice. The function of the support surface is to limit the penetration of the contact means into the ice.
