A crutch, or the like, that can handle ground conditions includes an elongate brace having a lower extension and an upper element. The upper element is adapted to engage a portion of the human anatomy. A device positioned at the lower extension includes a firm proximal member, and a firm distal member. The firm proximal member and the firm distal member are positioned below the upper end of the main body. Also included is an elongate flexible structure. This structure is adapted to engage the proximal member and the distal member, and allow them to angularly deflect relative to each other. An angular offset can then occur between the firm distal member and the main body. Also included is a base positioned below the distal member that has multiple feet.

A rotatable shock absorber assembly for a crutch. A guide pin is removably fixable within the upper portion of a support leg. A piston comprises a flange arranged proximate a saddle, comprising a top surface having two or more arcuate rotation grooves defined therein, and a main body defining an elongate slot enabling the guide pin to be inserted therethrough, such that the piston can translate along the elongate axis relative to the guide pin. A joint, can operably couple the piston to the saddle. The joint can rotate about the elongate axis relative to the piston. A biasing mechanism is configured to urge the piston along the elongate axis toward the armpit of the user whereby the saddle can be held stable in the armpit of the user and the support leg can rotate about, and translate along the elongate axis during use.

A gait assist apparatus having assemblies for a chassis, shock absorption, swivel wheel (casters), pivot, crutch and spring tension. The crutch is fitted onto an upper shaft of a pivot housing to pivot relative to the chassis. A pair of topside tension springs extend from a shock absorption plate to the middle of the crutch. A pair of underside tension springs extends from the bottom end of the crutch to the underside of the chassis. Suspension springs space the shock absorption plate above the chassis. One of the underside tension springs possesses a tension/compression force greater than that of the other tension springs. One of the topside tension springs possesses a tension/compression force greater than that of the other topside tension springs.

A crutch air cushion device, including an inflatable housing that slides on top of a crutch, where the inflatable housing includes an upper chamber and at least one side chamber, and a valve for air inlet and outlet. The device further includes an upper chamber has an outer surface on the outside of the inflatable housing and an inner surface on the inside of the inflatable housing, and the valve positioned on the inner surface of the upper chamber. A crutch air cushion device, including an inflatable housing with a plurality of air chambers, and a valve positioned on the inner surface of the inflatable housing that contact the upper surface of a crutch. A method of pressurizing a crutch air cushion device, including sliding an inflatable housing on a crutch, inserting air into the inflatable housing through a valve located on an inner surface of the inflatable housing, and filling an upper chamber and at least one side chamber of the inflatable housing with the air. A method further including removing the inflatable housing, modifying the amount of air pressure within the inflatable housing by opening and closing the valve to the user defined comfort level, and reapplying the inflatable air cushion on the crutch.

An ambulatory aid, such as a crutch, including a pair of support members connected by a load bearing handle member, and terminating at a first end with a top axilla-conforming member, and a second end with a foot piece. The crutch is used as a straight arm crutch, in which a user's weight is distributed in the hand to keep the arm straight, while preventing any load on the shoulder girdles. The crutches are configured to fit close to the body, to centralize the base of support, and keep the center of gravity lower, thereby keeping the body aligned as designed, and keeping the pectoral and pelvic girdles aligned. Proper body alignment during use results in greater stability and equilibrium of the user compared to traditional tri-pod creating crutches.

In one example, we describe a device for Crutches and Sitting Device as an improvement of the basic crutch to provide needed support to ameliorate potential injuries and improve ambulation for persons suffering from injured lower limbs, lumbar region or other injuries, and who frequently require using crutches for mobility. Normally, the conventional crutches require more energy from the user than merely walking, and frequently, a crutch user may require rest. Prior crutch systems have not provided a convenient way to provide the user with such rest. We have solved all these problems here. Many other different variations are shown here, as well, such as walkers and specially curved handles for better grip and less/no injury. Also, we show crutch support in sitting position that works as a simple and handy decompression system for herniated or bulged discs and injured/weak back muscles.

An improved crutch includes an improved shock absorbing mechanism, lighting components, and an improved tip component. The improved shock absorber mechanism utilizes compressible spheres that are compressed when a person supports all or partial of their body weight onto the crutch and are uncompressed when the weigh is removed. This compression of the spheres absorbs any impact from the walking surface to the person's body. The elasticity of the compressible spheres is adjusted by forming a central through-opening through the sphere, varying the number of the sphere, their diameter and material.

Hands-free walking devices and methods of constructing the same are described herein. The devices can include a receiving member to receive a portion of a patient's leg above a patient's knee and one or more hinges connected to the receiving member. One or more vertical members can be each connected to one of the hinges. A ground-contact member can be connected to the vertical members. The receiving member can transfer at least a portion of the patient's weight through the vertical members to the ground-contact member. The hinges can rotate about an axis about which the patient's knee also rotates while walking to support a natural gait.

The crutch is fitted onto an upper shaft of a pivot housing to pivot relative to the chassis. A pair of topside tension springs extend from a shock absorption plate to the middle of the crutch. A pair of underside tension springs extends from the bottom end of the crutch to the underside of the chassis. Suspension springs space the shock absorption plate above the chassis. One of the underside tension springs possesses a tension/compression force greater than that of the other tension springs. One of the topside tension springs possesses a tension/compression force greater than that of the other topside tension springs.

A base for a walking stick, which is configured to dispose in a bottom end of a stick body of the walking stick to provide a buffering and shock-absorbing effect, may include a main body, a shaft, a first sleeve, and a second sleeve. An upper portion and a lower portion of the shaft respectively have a first connecting portion and a second connecting portion. Also, a buffering unit disposed on the first connecting portion can allow the second sleeve to be compressed and stretched. Thus, the walking stick can achieve the stretch motion stably, and buffer the reactive force from the floor. Thus, the base structure for a walking stick can allow the stick body to swing in all direction. Also, it can be used to stand on different tilted grounds, and improve the reliability and safety of the walking stick.
