  • Patent number: 6286184
    Abstract: A caster is provided with two braking mechanisms and/or a locking mechanism. One embodiment of the present invention provides a castor including a wheel having an axis of rotation and a mounting bracket for a load. A brake lever is attached to the wheel adjacent the axis of rotation and pivotally attached to the mounting bracket. The brake lever is movable to selectively place the wheel and mounting bracket in a locked position or a rotation position. A first brake surface is associated with the mounting bracket and contacts the wheel when the wheel is in the locked position to substantially restrict wheel rotation. A second brake member, having a second brake surface, is linked to the mounting bracket and the brake lever so that the second brake surface contacts the wheel when the wheel is in the locked position. In an alternate embodiment, a lock mechanism is associated with the castor and is selectively engagable to restrict the wheel from moving from the locked position to the rotation position.
