Title: A nonskid tip for cratch
Inventor: JO SUNG WOO
IPC: A61H3/02
Filed: 2020-08-06
Abstract: The present invention relates to an anti-slip tip for crutches, in which a structure of an anti-slip tip for crutches is improved to a wrinkled structure to reduce pressure on the shoulder blades coming in contact with the crutches when a user uses the crutches. In the conventional tip for crutches, a groove is formed on a tip part to prevent slipping, but this is simply installing a rubber anti-slip tip at the end of a leg bar to be worked only when the tip is touching the ground flatly, so that a groove function is not possible when the crutches are tilted for walking, and thus anti-slip is not performed. In addition, impact on the ground is transmitted directly to the shoulder blades when the crutches are used, and thus strain and pain occur on the skin in contact with the crutches when the crutches are used for a long time. According to the present invention, the inner side into which the crutch is inserted is formed in a wrinkled structure so that a number of bends (4) are formed in a structure of tightening the crutch without deformation of the outer shape of the tip when the crutch is inserted into the tip. The middle part of a tip body (2) forms a curve (4) by being formed of a slender body. A corrugated deformation (6) is formed at a tip end part.
