摘要:
A wheel assembly (200) is disclosed comprising a mounting plate (210) for attachment to a rotatable axle, a plurality of friction plates or elements (220) engaging a corresponding number of notches (212) of the mounting plate (212), a first annular flange (230) fixed to first end portions of the friction plates or elements (220), a second annular flange (240) fixed to second end portions of the friction plates or elements (220), and a plurality of tension claws (250) fixed to the annular flanges (230, 240) adjacent the friction plates or elements (220). Also, a system for supporting a load is disclosed, the system comprising a tire assembly including a spoke structure (110) and the above wheel assembly (200). Friction plates or elements (220) and tension claws (250) cooperate to engage the spoke structure (110).

The invention is directed to novel wheels useful for various products including strollers, vehicles for children, carts, luggage trollies and bags, tricycles, bicycles and toys, and methods of production. The novel wheel comprising a flexible annular segment manufactured by a blow molding process, said segment having at least one layer made of a thermoplastic elastomer; and a wheel hub configured to support the flexible annular segment from each of its sides and to create a cylinder for insertion of an axle therethrough so as to allow connection of the wheel to other components of a product. In one alternative implementation of the invention, the flexible annular segment manufactured is manufactured by extrusion molding process. The invention is further directed to methods for manufacturing the novel wheel.

A locomotion assembly (20) is provided, suitable to be used in a vehicle. The locomotion assembly (20) comprises a frustum-conical structure (30) comprising at least one flexible member (34) having a frustum-conical surface extending between its relatively narrow (38) and wide (36) ends along a frustum-conical axis (A), the frustum-conical member (34) being reversibly deformable from its biased rounded shape corresponding to a frustum-conical shape in which its side elevation is circular into a deformed frustum-conical shape in which its side elevation is non-circular. The frustum-conical structure (30) may serve for supporting at least one surface-engaging member (22) convertible between a round wheel-like configuration, in which its side elevation is substantially circular, and a deformed configuration, in which its side elevation is non-circular and in which a larger portion (70) of the surface-engaging member (22) is in contact with a movement surface (72).

Safety apparatuses for objects having a nut are disclosed. Contemplated apparatuses comprise a nut cap and a nut rotation indicator that can readily be observed by an operator. A retention wall can also be included to operate in conjunction with an additional component to block a rotation of a nut. Apparatuses are preferably configured to remain stable in harsher environments.

A wheel assembly (200) includes a wheel (202) and a hub assembly (400). The hub assembly (400) includes a retainer housing (600), retaining member (700), biasing element (800), and restraining element (900). The retainer housing (600) includes a wheel mounting sleeve (602) and pin sleeve (604). The wheel mounting sleeve (602) includes an axle bore configured to receive an axle (150) and configured to be inserted within a sleeve bore (210) of the wheel. The pin sleeve (604) includes a first end fluidly communicating with the sleeve bore (210), a second end, and a conduit therebetween. The retaining member (700), disposed within the conduit, is configured to operatively engage an axle groove (152) and includes a lip (704) wider than a first end shoulder to prevent the retaining member (700) from exiting the first end. The biasing element (800), disposed within the conduit, is configured to bias the retaining member (700) towards the axle bore. The restraining element (900) is configured to prevent the retaining member (700) from exiting the second end.
摘要:
Disclosed is a injection molded composite wheel, including a polyamide composition including (A) about 20 to about 70 weight percent of at least one polyamide resin, (B) about 30 to about 65 weight percent of one or more fiber reinforcing agents wherein the fiber has an average length of 0.1 to 0.9 mm; and (C) 0 to about 20 weight percent of one or more polymer impact modifiers; wherein 4 mm test bars prepared from the polyamide composition have an average tensile modulus greater than or equal to about 9 GPa, and an elongation at break of at least 4 %.
