US Patent 7108640 Stilt device with improved leg attachment assembly

A stilt device for supporting a user above a base support surface. The stilt device includes a shoe plate, a base member and at least one intermediary strut. A leg attachment assembly comprises an elongated support pole which extends upwardly from the strut. In some embodiments, a clam-shell assembly is attached to a distal end of the support pole and comprises opposing, curved inner and outer plates configured to surround and support the user's leg. A hinge assembly facilitates rotation of the inner plate with respect to the outer plate between open and closed positions. In other embodiments, a support attachment assembly utilizes a u-shaped bracket and a nested, h-shaped clamp to attach the medial portion of the support pole to the shoe plate. The support attachment assembly establishes and secures both the angular extent and length of the support pole.
