ABSTRACT:
A cart for transporting computer instruments, and the like, from one location to another in which the rear rollers of the cart are mounted by torsion bars to decrease the likelihood of damage to the parts being transported. In one embodiment of the invention, the torsion bars are supported by connecting blocks that allow relative sliding movement of the two rollers to increase and the decrease the distance between the rollers to adapt the cart to the particular size and weight of the item being transported. In another embodiment of the invention, the handle portion of the cart is divided into two section pivotable relative to each other and pivotally connected to the main supporting frame of the cart for folding and collapsing the cart during nonuse.
