According to the invention, in order to be able to realize a locking device which is effective even for small wheel diameters, an inwardly pointing toothing is provided on an outer ring of the wheel core, wherein at least one aperture is formed in the outer ring between the tooth flanks, into which aperture a web, which is aligned axially in parallel and which is offset radially inward with respect to the running surface, of the wheel casing engages in a positively locking manner.

Abstract: Disclosed is a wheel device for a skate board or a roller skate. A wheel includes a single central hub having an exterior wall and a bore for the housing of rollers, the rollers providing the connection with the hub of a truck; and a tread removably mounted on the exterior wall of the hub. A shoulder of the tread includes a first support face and a second support face, the two faces being parallel to each other and perpendicular to the common axis. The tread is locked in rotation and in axial position on the hub by means of locking screws, including heads abut against the second support face of the shoulder, the screws traversing the shoulder from side to side and attaching on the connecting means of the hub.

Abstract: Wheels including one or more retention elements for affixing a polyurethane tire to a hub of the wheel are disclosed. The polyurethane tires of the wheels disclosed are manufactured separate from the hub and affixed to the hub via the retention elements thereby enabling additional manufacturing processes for the polyurethane tires and reuse of the hub portion of the wheels. Such manufacturing processes also allow for more complex polyurethane tire design and combinations of polymers to produce composite wheels allowing for increased comfort and durability. The wheels are particular suitability for use with industrial vehicles, such as lift trucks.

Abstract: A solid rubber tire with a flexible drive hub having a multiplicity of hub ribs and grooves formed around the periphery of the flexible drive hub and a solid rubber tire tread replaceably mounted on the flexible drive hub having a multiplicity of interior tread grooves and ribs formed around an interior surface of the tire tread, the tread grooves and ribs sized and shaped for interlocking engagement with the multiplicity of ribs and grooves formed around the periphery of the flexible drive hub.

Abstract: A skateboard wheel system for providing a skateboard wheel rim that can be uniquely designed while permitting easy replacement of worn wheels. The skateboard wheel system includes a rim member, manufactured in a plurality of designs and appearances, with a bearing pressed into both a first end and a second end and wheel member pressed about the rim member retained by a ring member. The rim member is comprised of an aperture for mounting the skateboard wheel system to the truck of the skateboard, a flange element located towards the first end for retaining the wheel member and a first threads towards the second end for retaining the ring member. The wheel member has a rib integrated to an interior surface for retaining it to the rim member. The ring member includes a plurality of tool apertures to be utilized while assembling the ring member to the rim member.

Abstract: A perdurable composite roller skating cylinder and methodology of making the same from low cost readily available commoditized commercial parts. In the in-line roller skating embodiment the cylinder will provide the combine features of long wear life, shock absorption and smooth running through the use of a rigid nylon core or equivalent and an appropriate longitudinal section of flexible polyurethane tubing or equivalent. This embodiment will permit flexure of the outer periphery of the perdurable composite cylinder in response to forces at the outer surface of the cylinder where it contacts the skating terrain surface. As the perdurable composite cylinder provides superior transverse angle joint support and unique cushioning for the foot. These composite cylinder attributes in an in-line skate embodiment will support an expanded dynamic roller skating maneuver repertoire.

Abstract: A vacuum cleaner includes a housing and at least one running roller operatively connected to the housing. The roller has a hub, a running ring, a wall connecting the running ring and the hub. The wall has two side surfaces and a curved cross-section between the running ring and the hub. The roller has at least one reinforcing rib extending at least from one of the two side surfaces of the wall and being in contact with neither the hub nor the running ring in a non-loaded state of the running roller. The roller forms an elastic caster with a nave and a bearing race. The nave and the bearing race are connected to another by an S or Z-shaped curved wall. Ribs are provided for reinforcing the wall or the nave.

Abstract: This perdurable composite cylinder methodology allows for the inclusion of load cushioning or shock absorbing at the primary site of the generation of the disturbance. This is accomplished because the core to covering interference fit of the composite cylinder form a perdurable mechanical bond between the two parts and the bond is of a constant resiliency at different sections of the resultant cylinder assembly, except at the center stress relieving section. This feature can be used to provide cushioning capability in the rollers for applications where none was present heretofore. This feature may also function to augment or eliminate existing auxiliary shock absorbing mechanisms.

Abstract: A wheel for an in-line skate includes a hub having a central stem, two symmetrical upper wings that extend oppositely and sidewisely from the central stem, and two symmetrical lower wings that extend oppositely and sidewisely from the central stem. A solid tire has a hub connecting ring portion that securely embraces and that radially and outwardly extends relative to the upper wings, and a ground engaging ring portion that axially reduces and that radially and outwardly extends from the hub connecting ring portion. The hub connecting ring portion cooperates with the upper wings to form an outer rim of the wheel that is capable of fulcruming about the central stem.

Abstract: An apparatus includes first and second wheel sections configured to mate in axially opposed relationship to define a rotatable wheel body. The wheel body has a peripheral outer surface extending circumferentially about an axis of rotation and a bearing cavity centered on the axis. Each of the wheel sections has an axial projection and an axial recess configured to receive the projection on the other of the wheel sections. This limits rotation of the wheel sections relative to each other about the axis when the wheel sections are received in the axially opposed relationship.

Abstract: A roller is structured so that one or a plurality of grooves are recessed on an outer peripheral surface of an outer race in a bearing, a part of a synthetic resin tire integrally adhered to the outer race of the bearing is inserted and welded within a groove on the outer peripheral surface of the outer race in the bearing, whereby a firmer adhesion force can be obtained. Accordingly, a more firmly adhered fitting body is prevented from being peeled off from the outer race of the bearing and the tire and the outer race of the bearing are prevented from separately racing even when the bearing is exposed to a heavy load and rotates at a high speed, that is, the roller is adhered so as to prevent the tire and the bearing from rotating relative to each other.
