Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to shoes such as dance shoes and women's shoes, and more particularly to attaching the heel of the shoe.

[0002]

2. Description of the Related Art Conventionally, the heel of a general shoe has been attached by an adhesive, screws, nails or the like and cannot be easily replaced. Further, a shoe in which the height of the heel, which is the heel, can be easily changed is described in, for example, Patent Document 1. In the shoe of Patent Document 1, when changing (increasing) the height of the heel, an additional heel is detachably attached to the original heel on the lower side. The attachment structure is a structure in which one elastic hook is hooked on the step portion, and when removing the additional heel, the hook is pushed by the operation button to remove the hook from the step portion.

[0003]

By the way, in the shoes disclosed in Patent Document 1 and the like, the height of the heel can be changed. However, when the heel is raised, the height between the original heel and the additional heel is increased. The joining surface of the is formed in the middle part of the newly joined heel, which makes it unattractive. Further, since the additional heel is supported by one hook at only one point (front side) by the hook, it is extremely unstable, and if force is applied from the left and right, the additional heel may fall off. Furthermore, it is possible to provide several hooks, but since it is necessary to provide an operation button for each hook, it is necessary to press multiple operation buttons at the same time when removing additional heels. It takes a lot of work.

[0024]

According to the present invention, since the heel body can be attached and detached, it is possible to easily replace the heel body according to the intended use. Further, since the projecting portion projecting from the sole plate of the shoe is fitted almost entirely into the recessed portion of the heel body, the coupling surface does not exist in the middle portion of the heel and the appearance is good. Further, the engaging portions are formed into a pair of bifurcated branches, and when the operating portion is operated, the engaging portions are engaged and disengaged at two places at a time. Therefore, even with only one operating portion, the heel body can be stably supported at two places. Further, since the engaging portion and the locking groove support the linear body instead of the point, the heel body can be attached more stably. Moreover, the distance between the pair of engaging portions becomes wider toward the tip,
As shown in FIG. 5, the sliding amount of the lock member required for engaging and disengaging the engaging portion and the engaging groove can be minimized. As a result, the engaging portion can be disengaged from the locking groove by slightly operating the operating portion.

Further, when the lock member is biased in the direction of engaging the locking groove by the biasing means, the engaging portion can be automatically engaged with the locking groove, and the shoe It is possible to prevent the heel body from accidentally falling off while wearing.

Further, when the ball urged by the elastic body is configured to fit in the ball recess, it is possible to prevent rattling at the joint portion of the heel body as much as possible.
