  • Publication number: 20040251649
    Abstract: A suspension structure for front wheel assembly of a wheelchair generally includes struts of front wheel assemblies disposed at corresponding mounting brackets of frame of the wheelchair. Such that the struts may rotate upward about the corresponding jockey wheels when the jockey wheels are passing a curb or other obstacle of the like, and meanwhile effects an uplift of the front end of the frame of wheelchair, as a result, the gravity center of the user move backward so as to reduce the load on the jockey wheels, by this way, the jockey wheels may traverse a curb or the like without difficulties. Furthermore, the suspension for front wheel assembly of a wheelchair is simple structured relative to conventional wheelchair so as to facilitate the assembly and reduce the production cost as well.

  • Patent number: 6826800
    Abstract: An insert-and-play caster assembly. The assembly includes a base frame and a caster for assisting transporting loads. The base frame can be easily inserted and fixed to the downward surface of a load, and thus one or more such insert-and-play casters are attached to a load so as to facilitate delivering the load. One section of the base frame is an insertion section composed of a number of staggered insertion plates. The insertion section is inserted into a seam of a load, such as a packing box. The insertion section provides a firm attachment to the load, and then the caster underneath the base frame becomes capable of assisting transporting loads, leading to the benefits of simple applicability and effort saving.

  • Publication number: 20040168283
    Abstract: A controlled caster wheel assembly which can be universally adapted to various support and directional control applications. The control mechanism is the caster beam assembly which attaches to a caster wheel assembly. The caster beam assemblies have both a cam/cam follower mechanism and a weight sensitive clutching mechanism which stabilize the caster wheel assembly thus preventing indiscriminate motion of wheel due to tire to contact surface variations. The controlled caster wheel assembly can be universally applied to any design which uses single or multiple wheels as support and directional control.

  • Patent number: 6592134
    Abstract: Method and apparatus for removably affixing a wheel assembly (20) near the end and the edge of a leg (24,27) of nearly any existing or newly manufactured ladder (22) to aid a person (26) transporting the ladder (22). A preferred embodiment includes a first wheel (30a) and a second wheel (30b) whose axles (32a, 32b) are disposed orthogonally. Each axle (32a, 32b) is supported by a bracket (34a, 34b) coupled to a clamp frame (36) which is clamped to said leg (24,27). When the ladder (22) is placed, edge parallel to a supporting surface (28), and a person (26) carries the opposite end of the ladder, the wheel (30b) will roll on that surface (28). When the ladder (22) face is placed parallel to a supporting surface (28) and a person (26) carries the opposite end of the ladder, the wheel (30a) will roll on that surface (28). The wheel (30a, 30b) will carry a large portion of the weight of the ladder (22). For persons who use ladders frequently, the system can prevent personal injuries.
