Abstract
An improved spring-loaded parallelogram stilt. An improved leg support attachment is provided in which the leg support is attached by a capturing bracket to the rearward vertical support. A nut and bolt pass through the capturing bracket, the bottom of the leg support and through a plastic block captured within the inside of the hollow tubular vertical leg support. A yoke structure is provided at the shoe platform level for providing further connection and adjustable support for the leg support. The yoke structure is of two pieces which surround the tubular leg support and has an inner surface made of a resilient material. The yoke structure is slidably engaged with a slot in a bracket attached to the outside of the shoe platform. The lower leg support attachment employing the capturing bracket and the yoke structure serve to prevent the leg support from accidentally becoming detached from the stilt. Improved straps are also provided, made of a suitable belt or strap material and have on the surface of the straps or belts hook and loop fastening material. The hook and loop fastening material is arranged on the surface of the straps such that multiple folds of the material create a firm, yet readily adjusted and released, attachment of the straps. This is achieved by having one flap of the strap having loop fastening material on both sides. The remaining surfaces of the strap are covered with hook fastening material. A gap or space is provided between the different fastening material patches so that fold lines are created in which a fastening buckle is engaged. The length of the strap is adjusted using an adjustment buckle.
