Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the creation and improvement of the soles of racing boots.

To be more specific, firstly, the ribs on the soles of the treadle are shaped so that they can dig into the road better at the bases of the fingers, where the most force is applied when starting a motorcycle or walking, especially near the bases of the thumbs. That's what I did with the ribs.

Second, by molding the ribs to run diagonally toward the outside of the little finger, when the outer surface assumes an inclined position when cornering a motorcycle, the sole of the shoe is designed to prevent the sole from digging into the road surface due to contact with the ground. The resistance can be converted to slip resistance using diagonal ribs.

Third, ribs are provided to prevent sideways slippage when force is applied to the footrest of the motorcycle (machine hold) while the motorcycle is running in the dirt.

Fourth, the foot position moves more smoothly from the ground to the toes while driving.

Fifth, some of the outer edges of the heel cut are made at right angles to improve the grip of the footrest.
The other parts are shaped into curved surfaces as before to make it easier for the feet to escape in case of an emergency.

[Conventional technology]

Conventionally, the soles of racing boots have been mainly designed to prevent slipping, and the invention for the soles of racing boots such as this one was first published in Utility Model Application No. 1983-207203 filed by the applicant. There is a "rib", and as an improvement idea for the heel, it was published in 11611, 1983.
No. ``Soles for riding motorcycles.''

[Problem that the invention attempts to solve]

However, the conventional shoe soles described above are still insufficient in terms of the ribs at the base of the thumbs digging into the road surface and the resistance to the road surface when the outside of the shoe soles touch the ground, and furthermore, the shape of the heel does not allow for retraction with respect to the footrest. Furthermore, no improvements have been made in terms of preventing slipping or shifting the foot position toward the toe due to the force applied to the footrest.

[Means for solving problems]

This invention adopts the following means to solve the above-mentioned drawbacks of the prior art.

That is, the sole S1, the foot foot S2, and the heel S3
The thumb side of the sole S1 of the shoe sole S is formed into a trapezoidal shape without a base, with a first top side R1 perpendicular to the center line of the shoe sole S, and the first top side R1
Oblique sides R2 and R3 are connected and molded on both ends of the , respectively, and a second top side R4 is connected and molded on the end of the hypotenuse R3 on the little finger side in parallel with the first top side R1. has a hypotenuse R parallel to the hypotenuse R3 above.
5 are connected and formed on the sole S1, with the hypotenuses facing both sides of the sole, and the cross-sectional shape of each side is a right triangle, and the first and second apex sides R
1. The gentle slope of R4 is formed to face the toe side of the shoe sole, and the rib R6 with an isosceles triangular cross section is formed on the foot of the foot S2, parallel to the center line of the shoe sole, and extends from the rising base of the heel S3 to the bottom of the foot. A part of S1 is formed into several straight lines, and gradually curved surface L1 is formed from the rising part on the outside of the sole of the heel S3 toward the inside of the sole of the shoe.
is formed into a large size to form the heel rising part, and the surface of the heel S3 has a rib R of the same shape as the rib R formed on the sole S1.
The sole of the racing boot is characterized by the number 7 being arranged side by side.

[Effect]

Since the present invention is constructed as described above, it exhibits the following effects.

First, the first, second, and second rows of top ribs are placed perpendicular to the center line of the shoe sole and have a right-angled triangular cross-section, with the gentle slope facing toward the toe and the right-angled portion biting into the road surface. Because it is placed in such a position, there is no risk of it digging into the road surface and slipping when starting a motorcycle or walking.

Second, since the hypotenuses connected to the first and second hypotenuses are both led to the inside and outside D portions of the sole, when the D portion of the boot touches the ground during cornering, the ribs will move in the direction of travel. On the other hand, since it is applied in the direction of flow, it prevents the ground contact surface of the boots from digging into the road surface.

Thirdly, a plurality of linear ribs with an isosceles triangular cross-section are applied from the foot of the foot to a part of the sole, which prevents the boots from sliding laterally and reduces resistance when moving from the foot of the foot to the toe. .

Fourthly, since the heel is curved inward from the rising portion facing the outside of the sole, the footrest can be stepped on reliably.

〔Example〕

The soles S of the racing boots are a set of symmetrical soles S1, foot S2, and heel S3, but for convenience of explanation, only one side of the sole will be explained.

The sole S1 has a first top edge R1 on the thumb side and little finger side,
It is formed by a group of ribs R on the second vertex R4.

The first top side R1 is placed at a position perpendicular to the center line of the shoe sole, and on both ends thereof, oblique sides R2 and R3, each having an internal angle of about 120°, are connected and molded on both sides. At the end is the first vertex R1
A second top side R4 of the same shape is connected, and this second top side R4 is located parallel to the first top side R1, and a hypotenuse side R5 is formed at the other end with an internal angle of 120°, The rib R, which has a shape formed by connecting the first and second apex sides, has a right triangular cross-sectional shape, and the gentle slopes are all shaped toward the toe side. The oblique side R5 of the second top side R4 is guided to the inside of the shoe sole S of the outer oblique side R2 of the side R1, and to the outer side D of the shoe sole.

Several ribs R6 having an isosceles triangular cross section are formed in a straight line from the heel rising base to a part of the sole S1 at positions parallel to the center line of the foot pad S2.

The curved surface L1 is formed into a shape that gradually becomes larger as it goes toward the inside of the shoe sole from the edge L of the rising surface from the soil base on the outside of the shoe sole S of the heel S3.

The surface of the heel S3 is entirely covered with ribs R7 having the same shape as the ribs R provided on the sole S1.

[Effect of idea]

Since this invention is constructed as described above, it has the following effects.

First, when starting a motorcycle, the most force is applied to the base of the thumb of the shoe.
Since a large number of first ribs are superimposed and molded at this position, it is sure to bite into the road surface, so there is no risk of slipping during cantering.

Second, when the outer periphery of the shoe sole touches the ground during cornering, the ribs formed on the outer periphery of the shoe sole are shaped to flow backward in the direction of travel, so there is no risk of the shoe sole digging into the road surface.

Thirdly, when applying force to a passenger car footrest,
Straight ribs are molded from the foot of the foot to part of the sole to prevent sideways slippage, and when moving from the foot of the foot to the tip of the foot (foot position), the several straight ribs allow for smooth movement.

Fourthly, the edge of the rising surface of the outer part of the heel S3 is formed at right angles, and the edge of the rising surface of the heel S3 is formed into a curved surface that gradually becomes larger as it goes toward the inside of the sole of the shoe, ensuring that the heel is caught on the footrest. , also improves the holding feeling of the footrest.

Furthermore, as mentioned above, the curved surface gradually becomes larger from the edge toward the inner side of the shoe sole, which is useful for evacuation in an emergency.
