Description

  The present invention relates to heels of various shoes such as men's shoes, women's shoes, and sports shoes, and shoes using the same.

  In a conventional shoe, a heel is fixed to a lower end of a heel body made of a hard resin with a lift made of a hard material or the like by an adhesive or a nail. When the lift was worn by wearing shoes, it was replaced with a new one.

  However, conventional shoe heels require special techniques for exchanging lifts, and thus cannot be easily replaced by amateurs. For this reason, it is the actual situation that shoes are exchanged by bringing them to a shoe repair shop or dealer, and there is a problem that it takes time and cost to replace the lift.

  In the present invention, even an amateur can easily replace the lift, the heel body is not easily broken or damaged, and static electricity is not easily charged to the human body while wearing shoes. The present invention also provides a shoe heel and a shoe using the shoe heel which are automatically discharged to the ground (earth).

  The heel of a shoe of the present application is a heel of a shoe having a heel body attached to the sole and a lift attached to the bottom of the heel body, the lower part in the heel body has a screw, the lift has a screw, There is provided a locking mechanism that allows the lift to be freely attached to and detached from the heel body by screwing of the screws, and that locks the heel body and the lift to prevent positioning and rotation of the lift. A metal vertical axis is embedded in the heel body in the vertical direction, a screw is formed at the lower end of the vertical axis, a metal connection shaft is attached to the lift body, and the base of the connection shaft is embedded in the lift body. Further, a screw is formed in a portion protruding from the lift main body, and the screw at the lower end of the vertical axis and the screw at the connecting shaft of the lift can be screwed together. The upper end of the longitudinal axis in the heel body is formed so as to contact or approach the magnet provided on the shoe sole, and the magnet is embedded in the lift body so as to contact or approach the lower end of the connecting shaft. When the screw of the shaft and the screw of the connecting shaft of the lift are screwed together, an electrostatic discharge system path of a shoe insole magnet—vertical axis—connecting shaft—magnet in the lift—earth is formed. A fitting space that protrudes downward from the lower end of the vertical axis in the heel body is formed inside the lower portion of the heel body, and when the screw of the vertical axis and the screw of the connection shaft are screwed together, the lower part of the connection shaft of the lift The part was fitted in the fitting space.
