摘要:
A caster assembly for a wheelchair comprises a stem having a frame clamp at afirstend and a fork clamp at a second end, the frame clamp configured to form aframe joint withat least one rotational degree of freedom with a frame portion of thewheelchair, a tighteningof the frame clamp securing the stem to the frame portion, the frame jointhaving a framerotational axis. A fork unit has a fork portion and a caster rotatablysupported by the forkportion, the fork unit having swivel mechanism, and a joint portion forming arotational jointwith the fork clamp of the stem, a tightening of the fork clamp blockingrotation of therotational joint, the rotational joint having a fork rotational axis. A vectorof the fork rotationalaxis is normal to a fork rotational plane in which the fork rotates relativeto the stem, andfurther wherein the frame rotational axis is not parallel to the forkrotational plane.
