Abstract

A length- and width-adjustable boot including: a forward base component (BA), a rearward base component (BP), a right side (LR), a left side (LL), and a locking system for said components. The four components (BA, BP, LR, LL) are linked together by rails. The slope of the rails of one of the bases (BP or BA), with regard to the axis of symmetry of the base of the boot, is determined by the length/width ratio of the foot. The movement of any of the four components causes a movement proportional to the width and length of the foot in the other three. The locking system locks the four components of the boot to be worn.

A length- and width-adjustable boot comprising: a forward base component (FB), a rearward base component (RB), a right side (RS), a left side (LS) and a locking system for said components. The four components (FB, RB, RS, LS) are linked together by rails. The slope of the rails of one of the bases (FB or LB), with regard to the axis of symmetry of the base of the boot, is determined by the length/width ratio of the foot. The movement of any one of the four components causes a movement proportional to the width and length of the foot in the other three. The locking system locks the four components for the boot to be worn.

Abstract

Adjustable elbow crutch with a main single piece that acts as leg-arm on which a handle and cuff are fixed, for which the handle includes an opening through which the leg-arm passes, said opening constituting an anchor for the handle on the leg-arm, where furthermore the leg-arm is made out of composite material, with an oval cross-section, and the leg-arm disposes of an initial lower segment that is vertical and which is followed in its upper part by a curved segment which defines a support angle. In this way a crutch is obtained that is light, easy to handle, easy and safe to adjust, which covers a continuous range of adjustments and which covers the largest number of possible user categories.

Abstract

The invention relates to an adjustable elbow crutch that has a single main piece that serves as an arm support (2) to which is attached a grip (1) and a cuff (3), for which the grip (1) has an opening through which is inserted the arm support (1), said opening becoming an anchor (5) for the grip (1) on the arm support (1), where the arm support (2) is made of a composite material and has an oval cross-section, and the arm support (2) has a first vertical lower portion (2.1), extending into a top part with a curved portion (2.2) that creates a support angle. This results in a crutch that is light, easy to handle, easily and safely adjustable, and that has a continuous adjustment range and suits the largest number of people.
