DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a basement used in civil engineering, construction sites, and the like, and to a core used therefor.

[0002]

2. Description of the Related Art A basement is generally constructed by attaching a rubber or synthetic resin grounding bottom to an upper sewn with a cotton cloth. It can be moved separately, it can be fitted to the foot, and because it uses a flexible grounding sole, it has the flexibility of foot movement, good feeling of grounding, and it can be worn lightly ing.

[0003] By the way, since the upper is made of cloth in the basement because of the requirement of lightness as described above, there is a concern that if an object falls on the toe during wear, the toe may be damaged. . For this reason, to protect the toe portion from falling objects, a metal cap-shaped leading core has been loaded in this portion, but separate leading cores covering the thumb and the four fingers are loaded. Then, especially at the basement, there are fingers, and this part becomes cramped, and the fingers may be rubbed or hit, so this improvement has been desired.

As a means for solving this point, Japanese Utility Model Publication No. 36
Japanese Unexamined Patent Publication (Kokai) No. 32459 discloses an underground tabi. In this baseball tabi, it is divided into thumb and four fingers, has a sloped cut in the finger or inner surface, and sandwiches a steel toe cover with a raised surface on the upper surface and a raised rubber surface. The insole is sutured. However, in the steel toe cover in this case, the sloped incision is provided from the top to the bottom of the toe crotch, so this part is extremely small on the lower side with respect to the upper side, and It is unstable and may fall down inside, and there is a concern that the toes may be pressed during use. From such a point of view, the steel plate toe cover in this proposal is provided with a raised projection surface on the upper surface,
It is supposed that the rubber sole and the insole had to be stitched at the finger or part when they were pinched on the tabi.

[0005]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention minimizes the contact and friction of the toes, especially at the crotch, with the fingers, does not require any special suturing, and has no toe. The present invention was studied by examining a basement having a simple structure and easy production while maintaining the protection function of the above, and a leading core used for the basement, and arrived at the present invention.

[0006]

That is, the gist of the present invention is to provide a thumb tip that is separately formed so as to cover the upper half of the thumb, and covers the upper half of the four fingers. And a four-finger tip core capable of being mounted on the toe portion of the upper, wherein at least one of the above-mentioned tip cores has an upper end and a lower end at a rear end of a finger crotch-side rising wall, and a middle part thereof is bored. Each underground is characterized by using a leading core having a cut-out portion formed in a removed state. Further, the present invention comprises a thumb tip that can be separated from each other to cover the upper half of the thumb, and a four finger tip that can cover the upper half of the four fingers. At least one of the leading cores has a notch at the rear end of the riser wall on the finger crotch side and has a cut-out portion formed by cutting out an intermediate portion thereof at the rear end thereof. Things.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings showing examples. FIG. 1 shows an example of a basement according to the present invention, in which a grounding bottom 2 made of rubber or synthetic resin is attached to an upper 1 made of a cotton cloth or the like by sewing, bonding, or both. In the drawing, 3 is a kohaze, 4 is a kohase thread, 1A is an upper surface cloth, 1B is a back cloth, 1C is an insole, 1D and 1E are a toe reinforcing cloth and a heel reinforcing cloth, respectively. .

According to the present invention, in the underground constructed as described above, the thumb core 5 for the thumb which can be separately provided to cover the upper half of the thumb A and the upper half of the four fingers B are covered. The four-finger tip core 6 that can be inserted into the toe portion of the upper 1, that is, between the outer cloth 1A and the toe reinforcing cloth 1D in the illustrated example, and attached via an adhesive if necessary It is. The two leading cores 5, 6 used in this embodiment
Are at the rear end of the crotch side rising wall, the upper end X and the lower end Y
Are used to form notches 5A and 6A in which the middle part is cut out in a substantially triangular shape, and the notches 5A and 6A are opposed to each other and are mounted on the toe. .

In the present invention, since the toe cores 5 and 6 having a unique shape as described above are used, when the toe reaches the toe crotch while wearing the basement, the notches 5A and 6A are used. There will be no walls in the part,
The finger will not hit. Since the outside of the cutouts 5A and 6A has the same configuration as that of a general underground cloth, the finger is not rubbed or hurt even if it comes into contact or rubs. The upper end X and the lower end Y of the rear end of the upright wall on the finger crotch side of the leading cores 5A and 6A used in the present invention.
Although the center of the horn is cut off, it maintains its initial substantially vertical position, so that even if a load is applied from above, it is stable and does not lean or fall over. In this regard, in the above-described conventional steel-made toe covers, the lower end is not located immediately below, so that the load is inclined or lacks stability. In addition, the tip cores 5A and 6A of the present invention.
Has a lower end Y, but since the outer surface of the toe bulges outward, the lower end Y hardly affects the finger.

In the above embodiment, the notches 5A,
6A is used, so that the thumb and the four fingers can be dealt with.
It may be provided on only one of the required cores.

The leading cores 5 and 6 used in the present invention can be made of synthetic resin, FRP, and various metal materials, as well as generally used ones. Usually, as shown in FIG. The folded part 5B is provided and molded. It is desirable that the notches 5A and 6A be formed at the same time when the cores 5 and 6 are formed using these materials. The shapes of the notches 5A and 6A are not only substantially triangular as shown, but also substantially semi-elliptical as shown in FIG. 6 (C) or a substantially trapezoidal shape shown in FIG. 6 (D). Also, when this notch is provided for both the thumb and the four fingers, the shapes of the notches may be the same as each other,
The shapes can be different from each other.

The leading cores 5 and 6 used in the present invention have the notches 5A and 6A formed in the rising wall on the finger crotch side. Therefore, when there is a concern about a decrease in strength, the leading cores 5 and 6 rise as shown in FIG. A thick portion 5C is provided at the edge of the wall, whereby the rigidity of this portion can be given to improve the strength. That is, as shown in FIG. 7, the thick wall portion 5C is provided at the edge of the rising wall provided with the cutout portions 5A and 6A, and this is provided outward as shown in FIG. 8A or as shown in FIG. May be provided on the inside or on both sides as shown in FIG. Further, when the rear ends 5C of the front cores 5 and 6 in this example are thinned in a wedge shape as shown in FIG. 3, when the front cores 5 and 6 are mounted on the toes, the corresponding portions of the upper 1 may bulge more than necessary. The step does not occur, so that the contact with the object can be prevented and the appearance can be improved.

As a means for improving the strength of the leading core for the same purpose as described above, a sheet piece 7 can be adhered to at least the periphery of the notch 5A as shown in FIGS.
That is, FIG. 9 shows an example in which the sheet piece 7 is adhered to substantially the entire surface of the finger crotch-side rising wall including the notch 5A of the leading core 5. Note that FIG. 9B shows the cross section. In this example, it is preferable to use a flexible natural or synthetic fiber cloth or carbon fiber cloth as the sheet piece 7 on substantially the entire surface of the finger crotch-side rising wall including the notch 5A and the periphery of the notch 5A. This has the effect of being deformed by the load applied to the leading core 5 (6), and eventually this portion is reinforced, and furthermore, it is possible to avoid finger contact and friction at the finger crotch.

FIG. 10 shows a modification of the above example.
(A) shows an example in which the sheet piece 7 is adhered to the peripheral portion of the notch portion 5A, and (B) shows the sheet piece 7 extending to almost the entire portion of the finger crotch side rising wall including the notch portion 5A. This is an example in which is attached. In these examples, since the sheet piece 7 is not located in the cutout portion 5A, a sheet piece 7 made of a hard material such as metal, synthetic resin, or FRP can be used, thereby exhibiting a reinforcing effect on this portion. Can be done. In the examples of FIGS. 9 and 10 described above, two or more sheet pieces 7 are adhered locally or over the entire surface,
Further reinforcement is also possible.

[0015]

Since the present invention has the construction as described in detail above, it is possible to minimize contact and friction at the toe, especially at the finger crotch, and it is necessary to perform a special stitching. Therefore, there is an advantage that it is possible to provide a basement which is simple in structure and easy to manufacture and a tip used therefor while maintaining the protection function of the toe.
