Abstract: A release mechanism especially but not exclusively for use in a prosthetic hand. The release mechanism includes a retainer and a release pin held within the retainer so as to be moveable between an engagement position and a release position. The retainer is provided with portions which engage the release pin to restrain it to movement between the engagement position and the release position. The portions include ball bearings to reduce the friction between the retainer and the release pin. Also, a prosthetic hand having such a release mechanism is provided so that the user can release the hand if it becomes jammed.

Abstract: A bearing cover assembly can be assembled to a bearing housing in which a rolling element bearing is accommodated. The bearing housing assembly includes an annular adapter and an end cap that can be mated together. The annular adapter can have a tapered inner annular surface and can be inserted into the housing bore of the bearing housing. The end cap can have a corresponding outer tapered surface. When the end cap is inserted into the adapter hole defined by the annular adapter, the sliding contact between the tapered inner annular surface and the outer surface radially expands the annular adapter inside the housing bore creating a positive engagement retaining the bearing cover assembly to the bearing housing.

Abstract: A wheel assembly for a model vehicle is provided. The wheel assembly may include a wheel base configured for mounting an R/C vehicle tire and a colored trim piece provided on a facing surface of the wheel base. In addition, the wheel assembly may include a wheel face configured to allow portions of the colored trim piece to be visible when the wheel face is attached to the wheel base. The wheel assembly may also include a hub cap assembly that comprises a hub cap and a retainer. Wherein the hub cap assembly is removably secured against the wheel base via the retainer.

Abstract: A bearing cover assembly configured to assemble to a bearing housing in which a rolling element bearing is accommodated. The bearing housing assembly includes an end cap with a sleeve portion that mates to an interior conical surface of the bearing housing with a complementary outer bevel formed on the sleeve portion.

Abstract: A spigot joint part of a wheel hub has a cylindrical outer peripheral surface. The wheel mounting structure includes a collared member having a collar part to be press-fitted into and fixed to the spigot joint part, which is formed at a position away from an end part of the spigot joint part by a predetermined distance to protrude outward in a radial direction of the collared member. An annular protruding part is formed on a part of an inner peripheral surface of a center hole of a wheel to protrude toward a center of the wheel. In a state where the wheel is fixed to the flange part by using hub bolts, a fitting part and the annular protruding part are spigot-fitted. In a state where the hub bolts are removed, the annular protruding part is locked by the collar part.

Abstract: A method for constructing a floating wheel cap using a modified original wheel cap. The original wheel cap is modified to provide a passage through the face of the original wheel cap and a positioning surface on the back of the original wheel cap. A fixed bearing retainer is fixedly attached to the back of the modified wheel cap using adhesive, and preferably using double sided tape. An offset weight floating cap is inserted through the passage in the modified wheel cap, through a bearing held in the fixed bearing retainer, and held in place by a ring. The offset weight floating cap is free to rotate in the modified wheel cap and includes an offset weight to urge the offset weight floating cap to a position displaying a design on the face of the offset weight floating cap in a desired position.

Abstract: A wheel cover for a wheeled vehicle which can be placed onto an associated wheel and secured using the same securing mechanism used to secure wheels to the wheeled vehicle. The securing member can be, for example, a nut typically used to attach wheels to the wheeled vehicle. The wheel cover can have a circumferential wall portion to cover a rolling surface of the associated wheel and a sidewall portion to contact a side of the associate wheel. The circumferential wall portion can have multiple features, such as protrusions, to reduce or inhibit rotation of the associated wheel when the wheel cover is attached thereto.

Abstract: A cover for a wheel-hub bearing made of plastic is provided. The cover includes an end wall that is arranged transversely with respect to a central axis (X) and a cylindrical mounting wall, which extends axially from one side of the end wall around the axis (X). The cover also includes a snap-action step that projects in a radially outwards direction from the cylindrical wall for locking the cover on a tubular appendage of the bearing a resilient ring that is arranged between an annular shoulder portion of the cover and the tubular appendage to exert a resilient recall action on the snap-action step.

Abstract: A flexible cover for an axle hub joint is provided. The flexible cover comprises a tubular member having a first end and a second end. The tubular member is configured to cover the axle hub joint. A first flange is defined at the first end of the tubular member and is rigidly attached to a wheel hub. A portion of the second end of the tubular member is configured to rotatably connect to a bearing groove and is free to rotate within the bearing groove.

Abstract: A hubcap configured for attachment to a wheel of a vehicle via a plurality of nutcaps that are removably attachable to a plurality of lugnuts of the vehicle includes a chrome-plated body and a standoff. The chrome-plated body defines an inner surface having a sidewall. The standoff is configured to distribute a force, arising during attachment of the plurality of nutcaps to the plurality of lugnuts, through the hubcap to the wheel of the vehicle. The standoff includes a proximal portion spaced apart from the sidewall and a distal portion including a hollow tubular member defining a bore. A wheel assembly configured for attachment to an axle of the vehicle includes the plurality of nutcaps, the wheel, the hubcap, and an insulator configured to protect the hubcap from heat and disposed within the hollow tubular member of the standoff.

Abstract: A method for producing a resin-molded article having openings which is free from a weld at a conjunction portion of synthetic resin flows and which exhibits excellent surface appearance and satisfactory strength provides a resin-molded article. This method includes injection-molding synthetic resin by using a mold, wherein the mold has a cavity which as projections for forming openings, projection-side peripheral portions surrounding the projections and a flow-rate changing means for making the flow rate of the injected synthetic resin different at each sides of each projection, and wherein the synthetic resin is injected into the cavity of the mold through a resin-injection opening.
