Abstract: A two-piece rim and tire assembly. The tire is held to the rim by fasteners extending through flanges integral with the tire main body and then into the rim. Further, the outer edges of the rim clinchably mount the tire main body thereto. A flexible overhanging portion extends outwardly of the tire main body minimizing dirt and mud accumulation on the tire and rim. A bearing is held within the rim by a ring.

Abstract: The present invention relates to a bicycle tire. More particularly, the bicycle tire is formed by foaming synthetic resin materials and is mounted to a rim of a bicycle, wherein the tire is prevented from being unexpectedly separated from the rim in use. That is, the bicycle tire formed by injection-foam molding is characterized in that: a rim coupling portion of the bicycle tire is formed with a plurality of coupling holes at predetermined intervals; and stoppers formed of synthetic resin materials are fixed in the coupling holes, stopped by annular holding protrusions when the tire is mounted to the bicycle rim, and formed of arch surfaces, horizontal surfaces and tilted both end surfaces so that the tilted both end surfaces are protruded when the stoppers are fixed to the coupling holes.

Abstract: A transmission assembly and a wheel thereof are presented, and the wheel includes a wheel frame and a tire skin. The wheel frame has a ring-shaped joint surface surrounding the wheel frame, and the joint surface is disposed with at least one slot. The slot has two opposite side walls and at least one stopping wall, and the stopping wall is located between the two side walls. The tire skin is ring-shaped. The tire skin is sleeved on the wheel frame, and attached to the joint surface. The tire skin has at least one protruding rib, and the protruding rib is located in the slot. The stopping wall limits displacement of the protruding rib in a direction of a wheel shaft, and the two side walls limit displacement of the protruding rib in a direction of rotation, thus achieving a good combination effect between the tire skin and the wheel frame.

Abstract: A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

Abstract: This improved bead locking apparatus and system is based on the provision of an expandable single and/or dual bead lock device with a bead compression ring that thrusts against the bead(s) of tire from the inside and is braced against and via the drop center of the wheel rim and/or an opposing bead compression ring. The aforesaid ring or rings are caused to press against the tire bead(s) via mechanical means actuated by a screw driver or similar implement. In single bead lock designs, the said implement can be inserted between the bead and rim on the side of the wheel opposite from that where the compression ring is located. In other designs, the said implement is inserted through an opening in the rim (which is preferably located in the drop center area of the rim) that is sealed with an O-ring, valve or plug.

Abstract: A low pressure tire including a torus of flexible, substantially inelastic material. The material will not deform at a temperature of about 225° F. The torus includes an inner diameter surface for engaging a tire supporting rim and an outer diameter surface for contacting a support surface. The torus can flatten under a load to facilitate movement of the tire over soft or irregular support surfaces. A sealable opening permits the inflation and deflation of the torus.

Abstract: A wheel is disclosed for use on land vehicles such as small manually drawn trailers and similar carriers, the wheel having a tire supporting rim (12) and a low pressure tire (48) engaging the rim, the tire comprising a thin walled torus (50) of elastomeric material, the torus having an inner diameter surface (52) engaging the rim, an inflation valve (54) and an outer diameter surface (56) for contacting a soft or irregular support surface; so that, the tire deforms or flattens substantially when it contacts such surfaces with an axle load applied to the wheel, thereby facilitating movement of a vehicle over such surfaces. A method of moving such vehicles is also disclosed.

Abstract: A wheel is composed of a rigid plastic inner section forming the wheel hub and rim and a resilient plastic tire section encircling the rim. A key formed integrally with the rim extends radially outward therefrom and interlockingly projects into the tire so as to mechanically connect the tire to the rim all around the wheel. The key can be formed with axially extending portions spaced radially outboard of the rim and terminating flush with the outer surface of the tire section so as to provide colored side wall decorations at one or both sides of the wheel.

Abstract: An assembly comprising a wheel rim and an annular safety support member mounted on the rim portion between the rim bead seats and extending radially outwards beyond the rim bead retaining flanges to support a tire mounted on the rim when in a deflated condition. The support member rotates with the rim in the non load-bearing condition but rotates relative to the rim in the load-bearing condition to compensate for circumferential differences between the tire tread and the radially outer surface of the support member. The confronting surfaces on the support member and rim portion are profiled to axially locate the support member on the rim. Preferably the radially inner surface of the support member is of shallow convex profile and the confronting surface on the rim portion is of shallow concave profile.

Abstract: Sealing means for a pneumatic tire and wheel rim assembly in which the wheel rim has a pair of axially spaced bead seats defined by grooves in each of which a respective one of a pair of axially spaced tire beads is located and retained. The sealing means comprises two seal elements each having a resiliently deformable portion which acts between confronting axially directed surfaces of the associated tire bead and bead seat to facilitate assembly and subsequently hold the tire bead under compression in an axial direction to prevent the tire bead slipping relative to the wheel rim.
