Claim:
1. A medical patient support arrangement, comprising: a platform configured to support a patient; a chassis attached to the platform; at least one wheel assembly movably coupled to the chassis, the at least one wheel assembly operable between a first state and a second state different from the first state; and an activation mechanism that controls the movement of the at least one wheel assembly with respect to the chassis, the activation mechanism including a track having a first stable position and a second stable position spaced along a length of the track, the activation mechanism further including a pin configured to travel along the track, wherein the at least one wheel assembly is in the first state when the pin is in the first stable position and the at least one wheel assembly is in the second state when the pin is in the second stable position, wherein the first state of the at least one wheel assembly is a raised state and the second state of the at least one wheel assembly is a lowered state, and wherein the movement of the at least one wheel assembly is a vertical movement between the raised and lowered states; and a movable input member adapted to receive an input from an operator, the input member operably coupled to the activation mechanism to move the pin between the first and second stable positions; wherein a first input to the input member from the operator moves the pin along the track from the first stable position toward the second stable position; wherein a second input to the input member from the operator moves the pin along the track from the second stable position toward the first stable position; and wherein the activation mechanism is configured such that the input member is moved in the same direction for the first input and the second input.
