Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a shoe last, and more particularly to a mounting structure for a metal heel plate that is attached to a heel of a bottom of a shoe main body.

<Prior Art> Conventionally, as a shoe mold used for manufacturing shoes, there is one shown in FIG.

That is, 1 is a shoe mold main body made of polyethylene or the like, and 2 is a heel iron plate fixed to the bottom heel of the shoe mold main body 1 by a nail 3.

In heel heeling, when a shoe bottom is made of leather, rubber, or synthetic resin and fixedly molded to the upper, the bottom of the upper heel part of the upper that is fitted along the shoe mold body 1 Is fixed to the insole, and then the outsole is brought into contact with the insole from the outside, and then a nail (not shown) is hammered to the peripheral edge to fix the insole.

In this case, the tips of the nails hammered from the outer surface of the outsole toward the insole hit the heel iron plate 2, so that they are turned over or turned sideways. That is, the nail tip is rounded for the safety of the sole and for improving the fixing property.

<Problems to be Solved by the Invention> However, in such a conventional shoe mold, the following problems arise due to the mounting structure of the heel iron plate 2.

That is, in most cases, the tip of the nail that is hammered into the outsole is
Although it hits the plate surface of the heel iron plate 2 when penetrating through the insole, it may hit the head of the nail 3 for fixing the iron plate exposed on the bottom surface of the heel iron plate 2.

As a result, the head of the nail 3 on the heel iron plate 2 surface is gradually worn away due to repeated use, the head diameter becomes smaller, and the head is pushed into the nail hole of the heel iron plate 2, and finally a depression hole is formed on the plate surface of the heel iron plate 2. Will be formed.

Therefore, if the tips of the nails that fix the outsole are driven into the recessed holes, the problem that the initial rounding of the nail tips, which is the purpose of the heel iron plate 2, cannot be achieved.

Moreover, the nail 3 for fixing the heel iron plate 2 comes back out due to the impact vibration when the periphery of the heel iron plate 2 is hammered by hitting the nail for fixing the heel material 5, and the fixing state of the heel iron plate 2 becomes unstable. There was also a problem that it became.

Further, in the conventional heel iron plate 2, when the heel iron plate 2 is attached to the bottom heel part of the shoe-shaped main body 1, it is necessary to make a habit according to the surface shape of the bottom heel part, and perform on-site work such as edging the edge. The installation workability is also poor.

In view of the above conventional circumstances, the present invention eliminates the above problems by eliminating the structure in which the metal heel plate attached to the bottom heel of the shoe-shaped main body is nailed and fixed. It is intended to provide a shoe last.

<Means for Solving Problems> Therefore, according to the present invention, in a shoe mold having a heel plate made of metal on a bottom heel portion of a main body, a plurality of protrusions for preventing slippage are integrally formed on a fixing surface of the heel plate part. It has a molded configuration.

<Operation> With this configuration, since the nail head is not exposed on the surface of the heel plate made of metal of the heel of the shoe-shaped main body, the tip of the nail for fixing the outsole to the insole and the upper is made of metal. There is no inconvenience that may occur when the nail head of the heel plate side is hit, and the rounding of the nail point, which is the purpose of the original metal heel plate of the heel, is completed. Further, there is no influence of impact vibration caused by hitting the nail for fixing the bottom of the bottom, and the fixing state of the metal heel plate on the heel does not become unstable. Furthermore, if the heel plate made of metal of the heel is formed by casting, it can be formed in a shape that matches the surface shape of the heel of the bottom of the shoe mold body in advance. No on-site work is required and assembly workability can be improved.

<Embodiment> Next, an embodiment of the present invention will be described with reference to the drawings.

1 to 3, the metal heel plate 6 for rounding the tip of the nail for fixing the outsole is attached to the heel of the bottom of the shoe-shaped main body 1 as in the conventional case. In the configuration, the metal heel plate 6 is integrally formed by casting with a plate portion 6A and a plurality of fixed attachment projections 6B with a retaining function that protrude from the back side fixing surface of the plate portion 6A.

Here, the fixed attachment projection 6B is provided with a large number of small projections 6b on the outer peripheral surface as a retaining function.
The metal heel plate 6 is also provided with a punched hole 6a as in the conventional case.

On the other hand, a mounting hole 7 for inserting and fixing the fixed mounting projection 6B is formed in the heel of the bottom surface of the shoe mold body 1.
Are provided at positions corresponding to. The mounting hole 7 is formed to have a diameter slightly smaller than the diameter of the protrusion 6B.

In such a metal heel plate 6, with the protruding portion 6B aligned with the mounting hole 7 of the bottom heel portion of the shoe mold body 1, by applying a striking force, the protruding portion 6B is press fit into the mounting hole 7. As a result, a fixed state is obtained.

According to this structure, the heel plate 6 made of metal on the heel of the shoe-shaped main body 1
Since a fixing member such as a nail is not exposed on the surface of the nail, there are various conventional inconveniences such as the tip of the nail protruding through the insole hits the head of the nail on the side of the metal heel plate 6. This does not occur, and the rounding of the nail point, which is the purpose of the metal heel plate 6 of the original heel, is completely performed. Further, there is no influence of impact vibration caused by hitting nails for fixing the bottom of the bottom, and the fixing state of the metal heel plate 6 on the heel does not become unstable. Furthermore, since the heel plate 6 made of metal of the heel is formed by casting, the heel plate 6 can be preliminarily formed into a shape that conforms to the surface shape of the heel of the bottom of the shoe main body 1. Also, on-site work such as edging of edges is not required, and the workability of installation can be improved.

<Effect of the Invention> As described above, according to the present invention, the rounding of the nail tip, which is the purpose of the heel plate made of metal of the heel, can be completely performed.
The fixed state of the metal heel plate can be maintained for a long time, and further, by molding the metal heel plate of the heel by casting,
Since it can be formed in advance to match the surface shape of the heel of the bottom of the shoe-shaped main body, there is no need for the on-site work each time, such as habit forming and edge scraping, as in the past, and installation workability can be improved. The effect is great.
