    Abstract: An upper U-shaped slide member and a lower U-shaped slide member are slidably coupled to form a generally rectangular framework. For storage, the upper and lower slide members are moved toward each other to reduce the size of the generally rectangular framework. A U-shaped rotating support member is pivotally coupled to said U-shaped slide members. Linkages couple the rotating support member to the lower U-shaped slide member and cause the rotating support member to rotate to a storage position when the lower slide member is slidingly moved with respect to the upper slide member. The linkages also move the rotating support member to a supporting position when the lower slide member is itself extended to a supporting position. Wheels coupled to the rotating support member and/or the lower slide member provide ease of movement of the frame. Extending the upper slide member provides a handle whereby the frame may be maneuvered readily.
