TECHNICAL FIELD OF THE INVENTION
The present invention relates to shoes such as dance shoes and women's shoes, and more particularly, to attaching heels to shoes.
[0002]
[Prior art]
Conventionally, the heel of a general shoe is attached with an adhesive, a screw, a nail, or the like, and cannot be easily replaced.
Further, a shoe capable of easily changing the height of a heel, which is a heel, is described in, for example, Patent Document 1. In the shoe of Patent Document 1, when the height of the heel is changed (increased), an additional heel is removably attached to the original heel on the lower side. The mounting structure has a structure in which one elastic hook is hooked on the step. When removing an additional heel, the hook is pushed in with an operation button to remove the hook from the step.
[0003]
[Problems to be solved by the invention]
By the way, in the shoes of Patent Document 1, etc., the height of the heel can be changed. However, when the heel is raised, the connecting surface between the original heel and the additional heel is newly connected. Formed in the middle of the heel, making it unattractive.
Further, the additional heel is supported by a single hook at only one point (front side), and is extremely unstable. When a force is applied from right and left, the additional heel may fall off.
Furthermore, it is conceivable to provide several hooks, but since it is necessary to provide operation buttons for each hook, it is necessary to press multiple operation buttons at the same time when removing additional heels, and to remove additional heels It takes time to work.

【The invention's effect】
According to the present invention, the heel body is detachable, so that the heel body can be easily replaced according to the intended use. And, since almost the entire protruding portion protruding from the sole plate of the shoe is fitted into the recessed portion of the heel body, the appearance is good because the coupling surface is not located in the middle portion of the heel. In addition, the engaging portion is formed as a pair that is branched in a bifurcated manner. When the operating portion is operated, the engaging portion is disengaged at two places at a time. Therefore, even with one operation unit, the heel body can be stably supported at two places. Further, the heel body can be attached more stably because the engaging portion and the locking groove support the heel body in a line instead of a point. In addition, the distance between the pair of engaging portions becomes wider toward the distal end, and as shown in FIG. 5, the amount of sliding of the lock member required for engaging and disengaging the engaging portion and the locking groove is minimized. Can be smaller. As a result, the engaging portion can be disengaged from the locking groove by slightly operating the operating portion.
[0025]
When the lock member is urged by the urging means in the direction of engagement with the locking groove, the engaging portion can be automatically engaged with the locking groove, and shoes can be worn. It is possible to prevent the heel body from accidentally falling off during the stay.
[0026]
Further, when the ball urged by the elastic body is configured to fit into the ball recess, it is possible to prevent rattling at the joint portion of the heel body as much as possible.
