Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a heel portion of a men's shoe, and particularly to a structure of a shoe sole in which a part of the heel can be replaced.

[0002]

[Prior art]

 As a general structure of men's shoes, an insole for placing a direct foot is attached to an upper (upper) made of front and back leather, and a heel as a sole is provided on this insole. . The heel is a heel land fitted with a heel base, which is usually integrated with a top lift made of a non-slip material.

With this top lift, the rear end side is easily worn away with use, and if this wear becomes remarkable, it will be comfortable to wear, but it will not look good, so other parts are not damaged. , The shoes will be discarded.

However, when the upper and the insole are not deteriorated, it is uneconomical to dispose of them. Therefore, hitting a metal stud or the like on the top lift and reusing the shoes has been conventionally performed. However, metal studs are no longer used today because of the abnormal noise generated when walking.

Therefore, it has been proposed to replace the entire shoe sole (see Japanese Utility Model Laid-Open No. 63-127403). This shoe sole is a heel base that is fixed as a top lift by fixing the replacement sole with nails.If the replacement sole wears, the pegs are removed and a new shoe sole is attached to ensure long-term use. It is intended for use.

[0006]

[Problems to be solved by the device]

 However, since the conventional replacement shoe sole replaces the entire sole comparable to the heel base, the amount of material used for the replacement shoe sole has increased. Therefore, the replacement bottom that is discarded by replacement is extremely uneconomical, and there remains a problem that the effect of replacement is reduced. In addition, since the replacement base is nailed to the entire base, the number of pegs inevitably increases, and the work of attaching and detaching the pegs becomes troublesome. The present invention aims to solve the above problems.

[0007]

[Means for Solving the Problems]

 The structure of the shoe sole of the present invention is characterized in that a part of the heel is detachably attached to the tip, and the heel chip has an asymmetrical shape in which the outside is wide and the inside is narrow with respect to the heel body.

[0008]

[Action]

 The structure of the shoe sole is such that the heel tip constitutes a part of the heel and can be formed into a small shape by confining it to the most worn portion, so that when the heel is worn down by the use of the shoe, the heel tip is When replacing the with a new one, only a small part needs to be discarded. Further, since the heel tip is small in shape, the amount of the mounting member used is reduced, and the attachment / detachment work associated with replacement is simplified.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a plan view showing the structure of a shoe sole, and FIG. 2 is a sectional view taken along line II-II in FIG. The structure of the sole of the present invention is applied to men's shoes such as Oxford shoes and slip-on shoes, and the heel tip 4 is detachably attached to the heel body 3 to form the heel 2 on the heel side.

A men's shoe has a general structure in which an insole 1 is attached to an upper (not shown), and a heel 2 is provided on the insole 1 via a heel sheet. In the present example, the sole for the left foot will be described, and the structure for the right foot has the same structure, and a duplicate description will be omitted. The heel body 3 has a heel land 3a and a heel base 3b attached to the heel base 3b. The heel base 3b is integrated with a top lift 3c made of a material excellent in slip prevention.

The heel main body 3 forms a step portion 5 for mounting the heel tip 4 on the rear end side, and two nuts 6 are embedded in the step portion 5. The step portion 5 is formed by obliquely cutting off the heel body 3 extending from the top lift 3c to a middle portion of the heel base 3b in a plan view. The nut 6 is embedded in the step portion 5 on the heel base 3b side. It should be noted that on the surface 5a side of the stepped portion 5, insertion holes for the + screw 7 to be screwed into the nut 6 are formed respectively.

The heel tip 4 is substantially fan-shaped in plan view, and has a thickness equal to the depth of the step portion 5 so as not to impair the aesthetics of the heel 2 when mounted on the step portion 5. A screw insertion hole is also formed at a position corresponding to the screw insertion hole, and an opening 4b having a diameter larger than that of the screw insertion hole is provided on the surface 4a side. A washer 8 which also functions as a reinforcement of the heel tip 4 is embedded in the inner part of the opening 4b.

By the way, the heel tip 4 is provided at a site where the heel 2 is most worn, and is made of a material different from that of the heel body 3. For example, when the heel body 3 is made of urethane, synthetic rubber, TR, and cheal, the heel tip 4 may be a mixture of urethane and synthetic rubber, or a mixture of ceramic powder with this mixture. Adopted. Alternatively, raw rubber or crepe rubber may be used. The heel tip 4 is usually provided with 2-3 identical sizes so that it can be replaced as needed.

When manufacturing, the heel tip 4 is firmly attached to the heel body 3 by coming into contact with the step portion 5 and screwing the screw portion 7a of the + screw 7 into the nut 6 from the opening 4a side. To be For this reason, there is no gap between the heel body 3 and the heel tip 4, and a sense of unity can be provided without impairing the aesthetic appearance. Also, when walking, a feeling of comfort similar to that of general men's shoes can be obtained.

When replacing the heel tip 4 with a new one, which is particularly worn when the heel 2 wears down due to use, loosen and remove the + screw 7, and then remove the new heel tip 4 with the + screw 7 And fix it on the heel body 3. Such attachment / detachment work is extremely easy because only two screws 7 are handled, and can be performed by anyone without requiring special technology.

Next, another embodiment will be described. As shown in FIG. 4 and FIG. 5, the structure of this shoe sole is such that the heel 12 mounted on the insole 11 is formed by the concave and convex fitting of the heel body 13 and the heel tip 14, and the basic configuration is the same as the above-mentioned embodiment. It is similar to the example, and detailed description is omitted. In the heel body 13, one nut 16 is embedded in the center of the step portion 15 to form a screw insertion hole. Further, on the surface 15a side of the step portion 15, two circular concave grooves 15c are provided along the side surface 15b, and one concave groove 15c is also formed on the side surface 15b.

On the other hand, the heel tip 14 is provided with an opening 14b on the front surface 14a side and a screw insertion hole for inserting the hexagonal screw 17 from the opening 14b toward the back surface 14c side. Further, a circular convex portion 14e is integrally formed on the back surface 14c and the side wall 14d corresponding to the concave groove 15c. The heel tip 14 is formed by fitting the convex portion 14e of the heel tip 14 into the concave groove 15c of the heel body 13 and manufacturing the shoe sole by screwing the hexagon screw 17 into the nut 16 at a predetermined position. Attach to 13. In this mounted state, since the heel tip 14 is closely attached to the heel body 13 due to the concave-convex fitting, the wearing comfort and aesthetics are further improved.

In the above embodiment, the case where the heel main body 3 and the heel tip 4 are provided on the heel side heel 2 has been described, but they may be provided on the toe side. Further, the invention is not limited to the application to men's shoes, but can be widely applied to various shoes as well as women's shoes.

[0019]

[Effect of device]

 As described above, in the structure of the shoe sole of the present invention, a detachable heel tip is provided at a portion where the heel is most worn, and the heel tip is adapted to the walking form, and the outer side is wide with respect to the heel body. Since it is a small piece with an asymmetrical shape with a narrow inner side, the amount of waste material due to replacement is small. Therefore, in addition to being able to extend the life of the shoe, there is an advantage that waste can be suppressed.

Further, since the heel tip has a small shape, the amount of the mounting member used for attaching to the heel body is smaller than that in the case where the entire sole is replaced as in the conventional case, and the replacement is accompanied by This has the effect of simplifying the attachment and detachment work.
