AI Technical Summary
Conventional crutches are large and heavy, making them difficult to handle and unsuitable for alternating walking, and they require separation from the body when sitting, limiting their usability in everyday life.
The crutches feature a telescopic shaft with a roller and brake mechanism, an upper storage pipe with a grip handle and locking mechanism, and a shoulder strap and upper arm band for secure attachment, allowing for adjustable height and independent movement.
This design enables users to walk alternately, use both hands freely when sitting, and easily move the crutches without lifting them, providing effective support and convenience in various situations.

Abstract
Description
[Technical field]
[0001] The cane is equipped with a shoulder strap and an upper arm strap to prevent the armpit pad from slipping off even if the hand is released from the grip. The grip handle has a function for locking and releasing the telescopic shaft, and when the arm is raised in the released state, the telescopic shaft can be stored in the upper pipe. When the cane is stored and the user sits down, the hand can move freely. The tip of the cane is a roller with a brake, which locks when pressed hard and rotates when released, allowing the cane to be moved without lifting the tip. Technical background
[0002] Crutches have armpit rests so that the body can be supported even without arm strength, but they are large, heavy and difficult to handle; by making the upper shaft into a pipe structure and fixing the armpit rests with a shoulder strap and upper arm band, and by adjusting the height as required, it is possible to sit with the crutches attached to the body when stored, and to use the hands freely; by making the tip of the crutch a roller with a brake, the tip can be moved without lifting the crutch. Summary of the Invention Problems that the invention aims to solve
[0003] Crutches support the weight of the body under the armpits, which reduces the burden on the legs, but they are large and heavy, making them unsuitable for alternating walking and causing the patient to walk like a rabbit. In addition, when sitting down, the crutches need to be removed from the body, making them inconvenient for everyday life. However, with wheels with brakes to move one foot forward at a time, an extendable shaft for sitting down, and a shoulder strap and upper arm band to release the hands, the crutches have an ideal structure as a walking aid.
[0004] It is composed of a shoulder belt, armpit pads with upper arm bands, an upper storage pipe with a grip handle with a locking mechanism, and a lower telescopic shaft with a roller with a brake mechanism. By extending the telescopic shaft when walking and storing it when sitting, it is possible to walk alternately, walk with both feet, and sit down, and both hands can be used freely when sitting down.
[0005] The height of the telescopic shaft can be adjusted as desired, and by resting your weight on the armpit rest when standing upright, you can use both hands freely. The roller with a braking mechanism at the end of the telescopic shaft allows you to change the position of the crutches independently for each side, allowing you to walk alternately. The grip handle with a locking mechanism allows you to free the lower shaft so you can sit down with the crutches attached to your body. The telescopic crutches are lightly secured to the body with a shoulder strap and upper arm band, allowing you to use your elbows freely when sitting down. When you stand up in this position, the telescopic shaft will naturally extend, so it will be locked at the required length. By shortening it, you can use it like a normal cane, and by lengthening it, you can use it like a normal crutches. [Brief description of the drawings]
