Abstract
A caster wheel assembly includes a vertical axis brake and barrier-traversing member. The caster shaft housing contains a vertically movable element with stator surface adjacent the caster wheel assembly. The barrier-traversing member with barrier contact surface is fastened to the caster wheel assembly. A braking surface member is attached to the barrier-traversing member opposite the barrier contact surface and adjacent the stator surface. In operation, the moving caster wheel assembly first contacts an obstacle with the barrier contact surface of the barrier-traversing member. The obstacle elevates the barrier-traversing member and attached braking surface member into contact with the vertically movable element of the stator surface of the caster shaft housing, thereby restraining rotation of the caster wheel assembly. Further forward movement of the rotation-restrained caster wheel assembly allows the barrier-traversing member to elevate the caster wheel, transfer load to the caster wheel, and thereby more easily traverse the obstacle.
