Abstract: A support arrangement having an activation mechanism to control the movement of wheels is provided. The support arrangement includes a platform, a chassis attached to the platform, a pair of wheel assemblies movably coupled to the chassis, and the activation mechanism. The pair of wheel assemblies are operable between a first state and a second state. The activation mechanism includes a track having a first stable position and a second stable position spaced along a length of the track, and a pin configured to travel along the track. Wheels are in the first state when the pin is in the first stable position and are in the second state when the pin is in the second stable position.

Abstract: A braking mechanism operably engaging at least one wheel where the mechanism is capable of transitioning the at least one wheel between unlocked and locked states is provided. The braking mechanism includes a flipper and a cam. The flipper is adapted to move in X, Y and Z-directions and includes a discontinuous track having an open slot portion and a surface path portion. The open slot portion includes a home position and an engaged position. The cam includes a pin which cooperatively moves along the discontinuous track. When the at least one wheel is in an unlocked state, the pin is in the home position and when the at least one wheel is in a locked state, the pin is in the engaged position.
