发明名称 STILT DEVICES WITH COMMON LEG SUPPORT ASSEMBLIES
摘要 A stilt device having a front extendible strut and a cooperating rear extendible strut pivotally connected to a base member and a shoe plate, the front and rear extendible struts being disposed in a parallelogram relationship. The rear extendible strut has a rear member and a rear extendible member. A leg support pole is supported at one end by the rear extendible member and extends for its other end to be connected to a workman's leg to provide stability and to thereby enable the replacement of height determining extendible members, the distance from the shoe plate being a common vertical difference that is unchanged the extension of the extendible struts or by components thereof. For stilts of increased height the springs of the damping assemblies are selectively stiffened.
