ABSTRACT:
A support frame having a plurality of wheeled assemblies, mounted at corners of the support frame, each wheeled assembly including a substantially identical mechanism for extending and retracting a respective wheel assembly. Each mechanism has a locking member which includes a locking portion for selectively engaging locking apertures on a rotatable member which rotatably supports the wheel assembly. Each mechanism also includes a grip, spaced from the locking member, to facilitate rotation of the rotatable member and the respective wheel assembly between extended and retracted positions when the locking portion is disengaged from the locking apertures. When each wheel assembly is in an extended position, the support frame is able to roll on a suitable surface. Each wheel assembly is also capable of being retained in a retracted position housed within a recess in its associated housing.
