Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a shoe pad used between a shoe sole and a shoe insole .

[0002]

2. Description of the Related Art Conventionally, pad bodies for shoe soles in which a urethane sponge material is formed into a shape corresponding to any of a toe portion, an arch portion, and a heel portion have been devised and put into practical use and known. .

[0003]

However, since the pad body for shoe soles made of urethane sponge material is soft, it can secure the cushioning property normally required when walking, but it is very easy to tear. Even if this is used in a shoe sole where it is required to be stiff like a sports shoe, the stomach is easily compressed and deformed or broken by the stiffness, so that the stiffness does not work .
As a result, it becomes less meaningful to use the pat body ,
There is a problem to be solved in that the processing for deforming the once formed pad body for shoe sole into a shape conforming to the required sole shape of each individual cannot be performed.

[0004] The present invention includes, over which is provided with a moderate hardness and cushioning that hold out a sharp, easy and safe pressurized <br/> heat after molding, by means of grinding or the like, easily Osamu to the required shape
It can be machined and fits the sole of the customer
The task is to provide a pad body for soles that can be used as soles.
I do.

[Means for Solving the Problems] In order to solve the above-mentioned problems
The means of the present invention will be described with reference to the drawings.
FIG. 2 is a plan view of a pair of pad bodies, and FIG.
FIG. 3 is a partially enlarged cross-sectional view showing the structure of the pad body for a shoe sole.
Is used between the sole sole and the insole.
Is a fiber for nonwoven fabric consisting of cork grains 1 and nylon fiber
2. Ethyl that softens above 50 ° C and cures below 50 ° C
Vinyl alcohol (EVA), polyethylene, isoprene
Or synthetic resin having thermoplasticity such as rubber or rubber.
Using a material mixed with a binder 3 that is a mixture of
The desired shape corresponding to the toe, arch, and heel of the sole
Toe pad 4, arch pad 5, heel pad
6 or any of them by molding means,
Softening due to relatively low temperature of 50 ° C or more by ear etc.
Nails characterized by being deformable
Tip pad 4, arch pad 5, heel pad 6, or
It consists of any of these.

[0006]

[Operation and effect of the invention] The shoe sole pad of the invention described above.
As in the past, the sole body consists of a sole sole and an insole
Between the insole and the insole.
Fiber for nonwoven fabric consisting of cork granules 1 and nylon fiber
2. Ethyl that softens above 50 ° C and cures below 50 ° C
Vinyl alcohol (EVA), polyethylene, isoprene
Or synthetic resin having thermoplasticity such as rubber or rubber.
Consisting of a material mixed with binder 3, which is a mixture of more than two species
It is moderate hardness and cushion
Performance and a temperature of 50 ° C or less
With the property that it can be softened and deformed by the relatively low temperature above.
Use a dryer that can be easily procured
Heating in a safe condition that does not cause burns.
Quickly and with little waiting time in the store
Deformed into a shape that fits the shape of the sole of the foot and fine correction
Can be ground using a file, etc.
Shoe sole that can be easily modified to the desired shape.
Can be provided.

Therefore, the pad body for shoe sole according to the present invention is
According to the idea of the present invention, a moderately hard
In addition to having cushioning properties, it is easy and
The required shape can be easily reduced by means such as full heating and grinding.
It can simply be modified to fit the customer's sole shape.
To provide a pad body for soles that can be
It can be achieved.
