Telescopic crutch with pure mechanical button switch for timely adjusting height

Abstract

The invention relates to a telescopic crutch with a pure mechanical button switch for timely adjusting height, which can be an underarm crutch or a hand-held crutch. When the button switch is pressed by a finger and a handle is pressed synchronously, the crutch becomes short, the height is reduced, and when the button switch is released, the height is kept; when the button switch is pressed by a finger and external pressing force is not applied on the handle, the crutch becomes long, the height is increased, and when the button switch is released, the height remains unchanged; in the released state of the button switch, the handle is pressed, and at the moment, the height state of the crutch is locked, so the height is not changed. The crutch, which is safe and reliable and is easy to operate and the height of which can be conveniently, timely and quickly adjusted to a height needed by a walker using the crutch, is obtained, and when walkers who have incomplete lower limbs and cannot conveniently walk or has difficulty in walking need to go upstairs from the horizontal ground or want to sit at positions lower than the standing position, the telescopic crutch brings great convenience to the walkers, thus enabling the walkers to walk with more dignity.

Description

technical field [0001] The present invention relates to a retractable crutch with a purely mechanical button switch for timely height adjustment. The crutch can be an underarm crutch or a hand-held crutch; the present invention also relates to a gas spring for adjusting the height of the crutch. It particularly relates to the piston mechanical locking mechanism of the internal piston assembly of the gas spring; the present invention also relates to a mechanical switch button that the user of the crutch presses down with one finger, and simultaneously holds the handle with his hand to It is convenient, timely, simple and fast to adjust the height of the crutch to the height required by the walker using the crutch by pushing down the retractable device below, and the finger releases the mechanical button switch and keeps the crutch at this time. A high degree of crutch use; a walker's walking aid. Background technique [0002] Crutches are walking aids for walkers. There are ...
