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.

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 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.
