Abstract
An assemblage for hand trucks which provides for interchangeable runners and wheels, as desired, to move the hand truck over a particular surface. The assemblage has a support frame which may be releasably secured to the frame of a hand truck and a supporting means which is releasably secured to the support frame to permit movement with respect thereto. The supporting means may be manipulated to rotate runners or wheels into contact with a surface while simultaneously rotating the wheels or runners out of contact with the surface. The support means may be releasably locked in position with respect to the support frame to ensure contact of the wheels or runners with the surface over which the hand truck is moved.
Claims29
An assemblage for use with a hand truck, the assemblage suporting a pair of wheels and a pair of runners such that the pair of runners and the pair of wheels may be interchanged to facilitate movement of the hand truck over dissimilar surfaces, the assemblage comprising:
- a support frame adapted to be releasably secured to the hand truck;
- and
- means for supporting said pair of wheels and said pair of runners such that when one of said pair of wheels and said pair of runners is rotated from an operative position in contact with said surface to an inoperative position out of contact with said surface, the other of said pair of wheels and said pair of runners is concurrently rotated from said inoperative position to said operative position, said supporting means being slidably secured to said support frame.
A hand truck utilized to transport loads, said hand truck having a pair of elongated leg members which are secured at one end thereof to a rectangularly configured load support, the improvement comprising:
- a support frame secured to said pair of elongated leg members of the hand truck;
- and
- means for supporting a pair of wheels and a pair of runners such that when one of said pair of wheels and said pair of runners is rotated from an operative position in contact with a surface over which the hand truck is to be moved to an inoperative position out of contact with said surface, the other of said pair of wheels and said pair of runners is concurrently rotated from said inoperative position into said operative position, said supporting means being slidably secured to said support frame.
