Abstract: There is provided an electric telescopic stick of which length can be easily adjusted quickly if needed by using only one hand by providing a multiple thread screw and providing a switch on an anterior portion of a grip portion including an electric motor which rotates the multiple thread screw in the forward and reverse directions. Further, in the electric telescopic stick, since a clutch is formed between the electric motor and the multiple thread screw, overload is not applied to the motor because the clutch idles when the movable stick portion is completely elongated. Further, a user can recognize the idling state from hitting sounds generated when steel balls are hit against holes when the clutch idles.

Abstract: An adjustable crutch, cane or similar walking aid for assisting everyday movement for temporarily injured and even permanently handicapped persons, the crutch having telescoping crutch tubes encasing a locking gas spring crutches which can instantaneously and controllably be adjusted in length during use, thereby considerably facilitating such common physical activities as sitting down, standing up, negotiating stairs or other obstacles and other similar everyday mobile activities. The locking gas spring functions by internal gas pressure and the telescoping crutch tubes are extended as the internal gas pressure seeks to reach the lowest energy state by maximizing its internal volume. For safety purposes a disengagement mechanism is provided so that extension occurs up to a preset level dictated by the user, and can even be overridden if desired.

Abstract: The present invention relates to an ordinary crutch modified with a straight support which may be formed from a solid, lightweight tubular member, said support connected at one end to near the bottom portion of the crutch and with a bicycle pedal-like cushion on the other end for which the calf, shin or cast of the injured leg or leg of the injured foot rests. Since the pedal can freely revolve from its attachment to the solid support member, the angle at which the leg rests on the pedal relative to the crutch may be readily optimized for the patient's comfort in order to relieve pain and discomfort. Also, fatigue from the body when supporting the dangling leg may be avoided as the leg no longer dangles with its concomitant “dead weight”, because the entire weight of the leg is resting on the cushion of the leg support, the knee is flexed or extended while standing, or while sifting.

Abstract: An ergonomically enhanced crutch that has a unitary upright member that is readily manufacturable and which has a upper section and a lower section that are generally straight sections.

Similarly, a bottom member is telescopingly affixed to the lower section and can be adjusted along the length of the lower section for the convenience and comfort of the patient. The upper arm cradle thus is angularly inclined upwardly in the direction the patient is facing to provide added comfort for the patient.

Abstract: A crutch 1 has vertical support pipes 2,3, a slider 10 slidably mounted on the support pipes 2,3, a grip 11 mounted on the slider 10, and a slider support system 12 for supporting the slider 10.

By changing the height adjustment hole with which the fixing pin 33 is engaged, the height of the grip 11 can be adjusted. No holes must be formed in the vertical support pipes 2,3 for constituting a crutch main body, and height adjustment can be carried out by manipulating only one fixing pin 33.

Abstract: A stick structure. The stick structure is resiliently extensible and adjustable in length. The adjustment of length of the stick can be easily achieved by both right-handed and left-handed users. The stick includes multiple fitting tubes nested in each other and an adjusting/locating device and a resilient extensible device disposed at the fitting sections of the fitting tubes. When rotating clockwise or counterclockwise any of the fitting tubes, the rotary body is rotated to forcedly stretch apart the damper to tightly abut against the inner circumference of another fitting tube so as to easily adjust the length of the stick and fix the stick. In addition, depending on use in different environments, the stick is freely and resiliently extensible to a certain extent.

Abstract: An improved crutch consists of a crutch pad, a main tube, an auxiliary tube, a handgrip and an adjustment tube. The adjustment tube is coupled with the main tube through the bottom end of the main tube to form an integrated body therewith and are extensible and adjustable to a length desired to suit users' requirements. The auxiliary tube is fastened to one side of the main tube. The hand grip is bridged between the main tube and the auxiliary tube to form a firm and steady crutch.

Abstract: A crutch constructed of two adjacently located, elongated, parallel upper and lower bows which can be moved in relationship to each other to form a vertical support of readily varied length. These bows have the same design and are therefore interchangeable, significantly reducing inventory requirements. Each bow has a series of parallel horizontal notches with the bows positioned so that the notches on each bow are on contacting surfaces. A pin inserted into parallel, adjacent notches on the two bows in cooperation with two or more collars or caps on the ends of one end of each bow fixes the relationship between the shafts which, in turn, defines the length of the vertical support. A similar concept can be used to lock a moveable centrally located lower bow between two parallel outer upper bows. This assemble provides a strong, adjustable length crutch for any height patient using only two different pairs of bow lengths.
