DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe sole structure.

[0002]

2. Description of the Related Art Usually, a shoe sole is composed of a main sole member 1, a lift member 2 and a heel member 3, as shown in FIG.

The lift member 2 is provided with a plurality of pins 2a integrally formed by insert molding or insert molding. The pins 2a are connected to the heel portion 1a of the bottom member 1.
It is press-fitted and fixed in the hole provided in the.

The heel member 3 is fixed to the upper surface of the heel portion 1a of the main bottom member 1 with an adhesive.

[0005]

Needless to say, the primer and the adhesive used for pretreatment for adhesion are harmful to humans and also have a risk of fire.

Further, there are many problems peculiar to the bonding process, such as protrusion of the adhesive from the bonding interface, defective bonding, insufficient bonding strength, and displacement of the heel member, which all lead to defective products.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shoe sole having a structure that eliminates environmental hygiene problems, improves workability, and does not cause defective products such as misalignment and defective adhesion.

[0008]

In order to solve the above-mentioned problems, in the present invention, a plurality of through holes are provided in the heel portion of the bottom member, and the lift member is press-fitted into these through holes and protrudes from the upper surface of the heel portion. A pin is integrally provided, and the heel member is
By providing holes into which the projecting portions of these pins are press-fitted, the lift member is fixed to the lower surface of the heel portion by the pins, and at the same time, the heel member is fixed to the upper surface of the heel portion.
Material that is U-shaped in the plane and is provided on the heel of the bottom member.
It fits inside the U-shape so that it is almost flush.
I'm sorry.

By doing so, the upper member is attached to the heel member.
At the same time, it can be fixed to the heel portion of the bottom member.

[0010]

The three members of the main bottom member, the lift member and the heel member are fixed by the pins, so that the positional displacement does not occur and the workability is good.

Further, by making the rib of the heel portion of the bottom member at the same level as the upper surface of the U-shaped heel member, the upper
Because it can adhere to the heel portion of the outsole member, even if the breaks off the lift member, the need to replace worn occurs, the rib of the heel portion of the instep and the heel member and the bottom member is fixed Therefore, the heel member does not come off from the bottom member separately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, the shoe sole of the present invention comprises a main sole member 10, a lift member 11 and a heel member 12.

The heel portion 10a of the bottom member 10 includes:
A plurality of through holes 10b are provided, and the pins 11a provided on the lift member 11 are press-fitted into these through holes 10b and project from the upper surface of the heel portion 10a. The protrusions of the pins 11a are press-fitted into a plurality of holes 12a provided in the heel member 12.

The pin 11a is the lift member 11
And a pin of iron or aluminum alloy may be insert-molded together with the lift member 11.

The pin 11a thus formed is
Through hole 10 provided in the heel portion 10a of the bottom member 10
The lift member 11 is fixed to the lower surface of the heel portion 10a by being pressed into b. The press-fitted pin 11a is
The heel member 10a projects from the upper surface of the heel portion 10a. When this projection is press-fitted into the hole 12a of the heel member 12, the heel member 1
2 is fixed to the heel portion 10a.

As shown in FIGS. 3 and 4, the main bottom member 10 has a tray-shaped cross section in order to reduce the weight, and ribs 10c are provided in the vertical and horizontal directions.
As shown in FIGS. 1 and 5, c is higher than the upper surface of the heel portion 10a at the location.

On the other hand, as shown in FIG. 2, the heel member 12 is substantially U-shaped or U-shaped, and the rib 10c of the heel portion 10a is fitted inside the heel member 12 and the top surface of the rib 10c is formed. The upper surface of the heel member 12 is substantially level with the upper surface of the heel member 12.

As described above, the rib 10c is attached to the heel member 12
When the upper 4 (see FIG. 6) is attached to the shoe sole by fitting it to the inside of the shoe and making it at the same level, the outsole member 10 and the heel member 12 are fixedly coupled to the upper at the heel portion. Therefore, even when the lift member 11 comes off or is worn and replaced, the heel member 12 does not come off.

Various materials can be selected for the main bottom member, the heel member and the lift member. For example, a flexible synthetic resin is used for the main bottom member and a hard synthetic resin is used for the heel member and the lift member. .

[0021]

According to the present invention, as described above, all the members are integrated by press-fitting the pin provided on the lift member into the main bottom member and the heel member. Therefore, application of adhesive or primer, pressure bonding, Work such as drying is not required, workability is greatly improved, and problems such as positioning of the heel member, insufficient joint strength, peeling and poor appearance due to the use of adhesives are eliminated, and quality is also improved. Can be measured.

Further, the upper and the bottom member together with the heel member
Since it is also possible to fix it to the heel,
Even if the lift member is removed due to wear or damage on the
The base member is not separated from the bottom member.
