Abstract: The modular components of an orthopedic leg brace assembly are secured together around a flexible cable arrangement and the components are removable so that they may be dissambled for repair or for replacement with longer components to accommodate for a user's growth. The components inlcude an ankle-foot orthosis and upwardly extending side braces of stanchion form with an upper securing strap arrangement for securely surrounding a user's lower leg, a second pair of side braces of stanchion form with an upper securing strap arrangement for securely surrounding a user's thigh, and knee joint assemblies joining the ends of the braces to simulate the normal action of a user's knee during flexion and extension of the leg. The flexible cable arrangement allows the user to rigidly hold the entire unit in aligned, fixed relation when the leg is extended.

Abstract: The modular components of an orthopedic leg brace assembly are strung together in bead-like fashion on a flexible cable arrangement and the components are removable so that they may be unstrung and replaced for repair or for replacement with longer components to accommodate for a user's growth. The components include an ankle-foot orthosis and upwardly extending side braces of stanchion form with an upper securing strap arrangement for securely surrounding a user's lower leg, a second pair of side braces of stanchion form with an upper securing strap arrangement for securely surrounding a user's thigh, and knee joint assemblies joining the ends of the braces to simulate the normal action of a user's knee during flexion and extension of the leg. The flexible cable arrangement allows the user to rigidly hold the entire unit in aligned, fixed relation when the leg is extended.

Abstract: A knife particularly for opening corrugated board cartons efficiently and safely without damaging the carton contents includes a forward end receptor slot for a standard single edge razor blade which positions the cutting edge of the blade below and forwardly of the hand grip portion of the knife for safety. An automatically retractable and recloseable blade guard having a cantilevered connection with the hand grip portion of the knife also serves as a cover for a blade storage compartment in the hand grip portion and is permanently attached to the knife to preclude loss. Depth of cut is limited to avoid damaging carton contents.
