Adjustable crutch

An adjustable crutch for facilitating mobility, comprising:

• a telescoping shaft having an upper and lower crutch tube aligned on a concentric axis;
• a handle attached to an intermediate portion of the telescoping shaft, a shoulder support attached to the crutch on a first end of the upper crutch tube and a ground engaging butt end positioned at a first end of the lower crutch tube;
• a locking gas spring comprising a gas cylinder and a moveable piston is positioned inside the telescoping shaft for controlling relative slidable movement between the upper and lower crutch tubes of the telescoping shaft;
• a control button is positioned on the handle for operating the gas spring, and an automatic disengagement mechanism is connected to the control button for automatically disengaging the control button from operation of the gas spring at a preset extension limit of the gas spring;
• and
• wherein adjustment of the handle causes the automatic disengagement mechanism to effect the preset extension limit of the gas spring.

A crutch adjustment system for aiding persons with mobile difficulties comprising:

• a crutch having a locking gas spring having a cylinder, a piston, a piston valve, and a piston rod;
• a manually actuated hydraulic button assembly for controlling the piston valve;
• a cylinder position follower for detecting the position of the gas spring cylinder;
• a locking rod, attached to the cylinder position follower, interlocking with the hydraulic button assembly;
• the locking rod disengages the manually actuated hydraulic button assembly as the cylinder position follower follows the gas spring cylinder beyond a pre-set location;
• and
• wherein the pre-set location of the gas spring is defined according to an adjustable positioning of the handle relative to the shoulder support.
