Abstract
Abstract A paired sporting device that consists of a knee contoured shell, here called knee boot, of light weight sheeting material, that engulfs the user's kneeling knee, covering the weight bearing area of the knee, the sides of the knee joint, medially and laterally and the upper 1/3 to 1/2 of the sides of the calf and the sides of the lower 1/3 to 1/2 of the thigh, being opened in the rear for entry and release, and provided with fastening straps to bridge over the user's lower thigh and upper calf. The device, preferably of firm and tear-resistant plastic is offered in two basically different versions: One where the described shell or knee boot is a one piece, continuous device, plus its fastening straps; the other, where the section of boot that holds medially and laterally the lower part of the thigh, bridged together in front of the user's thigh, is jointed or articulated upon the lower section of the said knee boot that bears the weight of the kneeling person, via a medial and a lateral flat joints. The one piece, non articulated knee boot version is fully open in front of the user's thigh from just above the upper lip of the user's patella bone, and its sections that cover the sides of the lower thigh are simply strapped together via an elastic strap that allows some knee flexion/extension. Either the one piece knee boot or the two piece, articulated version, are provided optionally, at the undersurface of the weight bearing area, with an ice-skate runner, or with a flat sole to sled or ski, or with a ski-boot specially shaped sole, or with a single or a double pair of roller skating wheels, for the different corresponding practical applications of the knee boot.
