  • Patent number: 11203230
    Abstract: The caster wheel support assembly has a first section securable to a frame member of a wheelchair and a second section holding a swivel member coupled to a caster wheel. The caster wheel support assembly has a holding member designed as a collet configured to hold a first portion of the swivel member which extends along a first axis. A second portion of the swivel member, which is coupled to the caster wheel, extends away from the first portion along a second axis which forms an angle relative to the first axis. The first portion of the swivel member is supported by the holding member to selectively allow rotation thereof relative to the holding member about the first axis, causing adjustment of a camber of the caster wheel. The collet is configured to selectively prevent or permit rotation of the swivel member relative to the holding member.
