Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adapter that allows boots to be manufactured using a shoe last for shorts.

Generally, the edge of short shoes is lower than the ankle, so the shape of the shoe shape around the ankle is adjusted to match when worn. Therefore, this cannot be used for boot-making shoes, so for boot-making shoes, a separate wooden last for boots is used, which has a thick part formed in the ankle bulge and the rear part of the ankle to provide extra space when stepping in. Must.

However, when producing shorts and boots alternately, the height position of the fixing device must be adjusted each time to fix the two lasts, which have different heights, to the shoe making machine. Efficiency and productivity were reduced. In addition, it is necessary to prepare wooden lasts for each size for both shorts and boots, which increases costs and requires double space and effort to store and organize.

The present invention was provided in order to eliminate the above-mentioned drawbacks, and its purpose is to provide a generally U-shaped plate-like material having an inner surface that approximately matches the outer circumferential shape of the ankle of a shoe last for short shoes. The bent part of the main body has a thick part for forming a foot space, and the outer surface has a swollen thick part for forming an ankle space.
This is achieved by an adapter for boot making, which is characterized in that it can be attached to a short shoe last through an attachable/detachable member.

The present invention will now be explained in more detail with reference to embodiments shown in the drawings.

Reference numeral 1 denotes an adapter according to the present invention, which is integrally molded from a hard plastic having some elasticity.
Reference numeral 2 denotes a plate-like main body of the adapter, and its inner surface is formed into a substantially U-shape so as to substantially match the outer circumferential shape of the ankle portion of the shoe shoe mold. Reference numeral 3 denotes a thick part formed on the U-shaped bent portion of the main body 2 to form a foot space, and 4 and 5 refer to thick parts bulged at appropriate positions on both outer surfaces of the main body 2 to form an ankle space. The upper part thereof is provided so as to protrude from the upper edge 21 of the main body 2. Reference numerals 61, 62, and 63 are detachable members for attaching to the wooden mold 7, and the figure shows a hook-shaped snap, and the paired snap is fixed to the wooden mold 7. (not shown).
Of course, other temporary attachments, such as a hook-and-loop fastener, may be used as the attachment/detachment member;
As shown in the figure, there are protrusions or protrusions 22 on the inner surface of the main body 2.
It may be formed integrally, and a corresponding recess or groove (not shown) may be provided on the wooden mold to be removably fitted and fixed. Reference numeral 23 denotes a reinforcing plate formed inside the U-shaped bent portion of the main body 2, and may be appropriately provided as necessary. Therefore, snap 63
may also be an optional component.

As shown in FIG. 4, the adapter 1 of this invention can form the foot space and ankle space required for making boots by simply fitting it into the wooden last 7 for making short shoes. . Therefore, by simply attaching and detaching the adapter 1, it is possible to manufacture both shorts and boots using the same mold, which significantly improves production efficiency and eliminates the need to prepare duplicate expensive molds. It is economical and has great practical effects.
