Description

Easy walking and standing crutches {A CRUTCH}

The present invention relates to an easy walking and standing crutches improved crutches used as a means of assisting the walking of a person who is uncomfortable to walk.

In more detail, a pair of support frames in which the upper support frame and the lower support frame are integrally installed to face each other before and after the bottom of the shoulder rest is installed so that a handle is installed between the upper support frame and between the lower support frame. The crutch support frame is fixedly installed, and the crutch tip is fixed to the bottom of the crutch support frame. Provides easy walking and standing crutches that can be easily walked while the crutches of the crutches are stretched, and the crutches of the crutches that are installed dually maintain two support points. I will.

Crutches are typically a kind of cane that walks along the armpits to make walking (and behavior) easier for a person who is inherently uncomfortable with a leg or who has a disability, such as a fracture or disease.

Commonly used crutches are made of light metal, such as wood or aluminum.

Commonly known crutches have been proposed in the Republic of Korea Utility Model Publication No. 20-1993-2163 (crutches), a pair of support frames formed integrally with the upper support frame and the lower support frame at the bottom of the shoulder rest It is installed, the handle is installed (fixed) between the upper support frame, between the lower support frame is to install the crutch support frame fixed crutch tips at the bottom.

However, this is because only one crutch tip is provided and the crutch tip is fixed, it is not easy to walk, and even when standing, one (one point) relies on one crutch tip, so it can not be easily stood because it swings back and forth.

Proposed in order to solve such a problem is proposed domestic public utility model publication No. 20-2000-6074 (crutch) and public utility model publication No. 20-2011-5822 (shock buffer function Crutches with adjustable handles) and Utility Model Registration No. 20-408369 (Crystal with auxiliary legs) and Publication No. 10-2011-45132 (standing brace) and Patent Registration No. 10-1075311 (ergonomic crutches) ) Is proposed.

Public utility model publication No. 20-2000-6074 (crutches) and public utility model publication No. 20-2011-5822 (handle adjustable crutches with shock absorbers) with a crutch tip provided alone The support shaft (or connecting portion) is to be shot by the coil spring.

However, since they are provided with a single crutch tip that is elasticized by the coil spring together with the support shaft (or the connecting part), they cannot stand easily because only one support point is formed, and the crutch tip that forms one support point even when walking Rather, there is a fear of hindering walking.

In addition, Utility Model Registration No. 20-408369 (a crutch with auxiliary legs) and Publication No. 10-2011-45132 (standing brace) have three crutch tips at the bottom of the support shaft (or connecting portion) in a triangle shape. It is arranged and formed so that the crutches arranged in a triangle can stand more easily.

However, this is because the fixed crutch tips are arranged in a triangular shape, so each time you step on the crutches, one of the triangular crutch tips is in contact with the ground first and the other (either or both) It is rather unnatural to walk on the ground. Whenever three fixed crutch tips come in contact with the ground, the impact is applied to the armpit or wrist of the pedestrian so that the pedestrian feels pro easily.

In addition, Patent Registration No. 10-1075311 (ergonomic crutches) is provided (installed) to each of the piston (cylinder) at the lower end of the pair of support (upper support) provided on the lower side of the shoulder rest, each piston ( In the cylinder), each of the piston rods with a crutch tip (fixed) at the bottom of the cylinder is sealed to prevent the air from the piston (exposed to the outside), so that the piston rods can be operated upside down (up or down). As a result, the pair of piston rods can stand somewhat easily because they hold (form) two support points.

However, this means that the piston rods installed (installed) on each piston (cylinder) operate opposite to each other, but when each piston (cylinder) loses its sealing capacity, the piston rods do not operate oppositely (rising or falling). When the piston rod is fully inserted into the piston (cylinder), the shock applied to the crutch tip is transmitted to the pedestrian so that the pedestrian can feel the pro easily.
