ABSTRACT:
A cart for injured persons, designed as an alternative to crutches for individuals with an injured leg. A padded leg support surface provides a comfortable location upon which the injured leg (or cast) may be rested. The cart is propelled by the individual using the uninjured leg. The front of the cart includes two wheels mounted on forks each having a handle bar that extends upwardly. A front pad is attached to the handle bars to provide a comfortable surface for the user to lean against. Hand brakes are also included for gripping opposing sides of the front wheels to brake the cart when brake levers on the handle bars are activated. The upper ends of both handle bars also include an elastomeric hand grip. The padded leg support surface is supported by a leg support assembly that is configured to be attached to either side of the cart. This allows a user to accommodate a left or a right injured leg. The leg support assembly has three tubes that are received within either three right sleeves permanently attached to the right front fork, or three left sleeves permanently attached to the left front fork. The leg support assembly includes a swivel for pivotally mounting a rear fork and an associated rear wheel to the leg support assembly. An adjustment mechanism is provided for changing the height of the leg support surface.
