Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for sports shoes worn for sports such as running and jogging, as well as special shoes. The present invention relates to soles to be attached to various types of shoes that require anti-slip properties.

0002

[Conventional technology]

Conventionally, in order to provide an anti-slip effect to the sole of the shoe, there have been a number of For example, the shoe sole with a notch is shown in Japanese Utility Model Publication No. 37-28728. be. Such shoe soles have a mountain on the contact surface due to the displacement of the notch when stopping suddenly. The purpose is to form a shape and provide an anti-slip effect at the chevron-shaped portion.

0003 However, such conventional products are made by simply making several cuts on the smooth sole of the shoe. Therefore, when landing, almost the entire surface of the sole is in contact with the ground, and each part of the sole is in contact with the ground. Because the notches are tight with almost no voids formed between them, the contact surface of the sole forms a chevron. It has the disadvantage that it is difficult to cause displacement to the extent that it does, and it is difficult to obtain the expected anti-slip effect. Ta. In addition, the thickness of the entire sole of the shoe is required to form the notch, which increases the weight of the entire shoe. As sports shoes for running, jogging, etc. that emphasize lightness. was not suitable.

[Problem that the idea aims to solve]

Therefore, the present invention has a structure that can overcome the deficiencies of the conventional shoe soles mentioned above, that is, it is lightweight. Our technical goal is to provide a sole that has an anti-slip effect without impairing the wear and tear, and has excellent shock absorption. This is an issue to be addressed.

[0005]

[Means to solve the idea]

In order to solve the above problems, the inventor of this invention has conducted extensive research and has developed the following configuration. We have come to provide an idea that has the following features. That is, the present invention provides a shoe sole having a large number of anti-slip protrusions on the contact surface side. Each anti-slip protrusion is integrated into the arbitrary block-shaped recess formed at the base of the sole. protruding from the bottom, with at least its tip protruding above the horizontal plane of the base of the sole. , and a single or multiple incisions or narrow grooves are formed perpendicularly from the top of the tip. This is a shoe sole with a new configuration.

[0006]

[Effect]

Therefore, according to the present invention, when landing, the first thing that is formed at the base of the sole of the shoe is the The protrusions that protrude integrally from within the concavity of the arbitrary block shape touch the ground, and the top of each protrusion Each protrusion divided by several notches or narrow grooves perpendicularly from the Displaces greatly to the rear or left and right to form a chevron on the ground contact area to effectively prevent slipping. Ru. In particular, water on the road surface can be drained through such cuts or grooves, and water on the road surface can be This prevents slippage caused by the sole surface of the shoe, which is the action surface, and changes the protrusion 1. Highly efficient anti-slip force due to the synergistic effect of the position and drainage action of the notch or narrow groove. can demonstrate. In particular, each protrusion is made to protrude from within the recess of an arbitrary block shape. Therefore, the height of the protrusion is determined by the depth of the indentation and the length of the protrusion upward from the base of the sole. The projection can be formed to be longer by a certain amount, and the displacement of the projection can be increased.

[0007] In addition, the notches on the protrusions not only drain moisture from the road surface, but also By appropriately changing the depth, width, and number of cuts, the flexibility of the protrusion itself can be improved. Since the cushioning properties can be varied, depending on the purpose of the shoes being worn, In addition, by making various changes depending on the road surface condition, extremely effective shock mitigation function can be achieved. We can provide shoes with

【Example】

Embodiments of the present invention will be described below based on the drawings. As shown in Figure 1, this invention is based on a shoe sole that has many anti-slip protrusions on the ground surface. Each of the anti-slip protrusions 1 is an arbitrary block-shaped recess formed on the base 2 of the sole. It protrudes integrally from inside the sole 3, and at least its tip 4 is exposed to the water at the base 2 of the sole. It is formed to protrude above the plane. Further, the protrusion 1 hangs down from the top 5 of the tip 4. Several cuts or thin grooves 6 are directly provided.

[0009] The one shown in FIG. A cylindrical projection 1 having a protrusion 1 is projected, and two thin grooves 6 are formed at the top 5 of the projection 1. It shows. In this case, the sole of the shoe with a foot length of 25.5 cm is used as the standard. In the case where the diameter of the circular recess is set to 10 mm, the above The depth 7 of the recess 3 is approximately 1 mm to 4 mm, and the height of the protrusion 1 is 2 mm to 5 mm. The height of the protrusion 1 protruding from the horizontal surface of the base 2 of the sole is always 0.5 mm or less. It is desirable to form it to about 2 mm. That is, the depth of the recess 3 is as shown in FIG. , when the protrusion 1 tilts in either the left or right direction due to the landing pressure of the shoe wearer, a dent occurs. The position where the mouth edge 8 of No. 3 supports the fall of the projection 1, and is an element of the displacement of the projection 1. The height is taken into consideration.

0010 Note that if the protrusion 1 is formed high and its displacement is too large, the strength and durability of the protrusion 1 itself will be reduced. On the other hand, if it is set too low, the protrusion 1 itself will undergo a large displacement. will not occur, and the initial effects will not be obtained. Also, in order to increase the depth of the dent, it goes without saying that the absolute thickness of the sole must be increased. This impairs the lightweight nature of the shoe. Therefore, the dent 3 The depth and the height of the protrusion 1 are appropriately set in consideration of the above-mentioned conditions.

[0011] In addition, the number of notches or narrow grooves 6 provided on the top 5 of the protrusion 1, the depth thereof, and the groove The width is also set considering the flexibility, strength, durability, etc. of protrusion 1 against landing impact. However, considering the depth of cut or the displacement of each block divided into narrow grooves 6, Set. FIGS. 4 and 5 show that inside a recess 3 having a rectangular block shape, there is a similar small outside. This shows another embodiment in which a protrusion 1 having a shell shape is protruded. Also, Figure 6 shows the shape It is formed by combining various protrusions 1 of different shapes. Of course, the button formed on the sole of the shoe What are the shapes and sizes of the lock-shaped recess 3 and the protrusion 1 protruding into the recess 3? However, the tip of the protrusion 1 may protrude above the horizontal surface of the base 2 of the sole. It can be set to any shape or size under the condition that

0012 Further, the recess 3 and the protrusion 1 protruding into the recess 3 are provided on the entire surface of the sole. In addition to the above, focus is placed on the front part of the sole of the shoe or the heel where landing pressure is likely to be applied. By forming it in a specific manner, effective impact mitigation and anti-slip effects can be obtained. Furthermore, the direction of the protrusion 1 protruding into the recess 3 or the direction of the notch or narrow groove 6 is provided on at least another adjacent non-slip protrusion 1 as shown in FIGS. 4 and 8. If the shoes are formed in different directions, the frictional resistance on the contact surface of the sole can be increased. It is possible to obtain even more effective anti-slip force.

[0013] Furthermore, although the notch or narrow groove 6 made in the protrusion 1 has a straight planar shape, Alternatively, it can be formed into a waveform as shown in Figure 5, or in a lattice shape as shown in Figure 6. You can also do that. Next, FIGS. 7 and 8 show a lower stepped portion 1 that surrounds all or part of the outer periphery of the sole. 0, and the lower stepped portion 10 is the same as or higher than the protrusion 1. The figure shows the shapes formed at equal widths. In this case, the lower stepped portion 1 0 has the function of supporting each protrusion 1 protruding from the sole surface on both the left and right sides of the shoe. . That is, when landing, the lower stepped portion 10 and the protrusion 1 contact the ground first, and the shoe When the wearer experiences landing pressure, the sole surface of the shoe curves toward the ground using the lower stepped portion 10 as a fulcrum. This causes the anti-slip force of the protrusion 1 to act on the ground.

[0014] Therefore, since the lower stepped portion 10 is configured to support the protrusion 1 on both left and right sides, Since the anti-slip force is activated only when landing pressure is applied, early wear of protrusion 1 is prevented. It has the effect of preventing wear and maintaining its durability for a long time. In particular, the periphery of the toes By providing the lower stepped portion 10 in the lower part, it is possible to avoid getting caught, which is likely to occur when landing. This can be naturally prevented. The height of the lower stepped portion 10 depends on the hardness and flexibility of the sole. , and are formed at an appropriate height taking into consideration the purpose of use of the shoes and road surface conditions.

[0015]

[Effect of the idea] Therefore, according to the present invention, the shoe sole protrudes integrally from within the arbitrary block-shaped recess of the shoe sole. The protrusions are cut vertically from the top of each protrusion, and several notches or thin grooves are made vertically from the top of each protrusion. By increasing the displacement in the load direction due to the landing pressure of the , each divided protrusion 1 is largely displaced back and forth or left and right to form a chevron at the ground contact part. This provides an effective anti-slip effect. In particular, it is important to remove moisture on the road surface from cuts or fine lines. Drains water from the grooves and prevents slips caused by the sole surface of the shoe, which is the surface on which water acts on the road surface. It can prevent slippage and exhibit effective anti-slip power. In particular, each protrusion is an arbitrary block. Since it protrudes from within the dent in the shape, the height of the protrusion is determined by the depth of the dent and the sole of the shoe. It can be formed into a long piece by the length that protrudes upward from the base, making it possible to reduce the displacement of the protrusion. It is possible to make it bigger. In addition, the notches on the protrusions are designed to drain moisture from the road surface. In addition to applying the action, we can also change the depth, width, and number of cuts as appropriate. This makes it possible to change the flexibility and cushioning properties of the protrusions themselves, making them easier to wear. By making various changes depending on the purpose of the shoes or the road surface conditions, Therefore, it is possible to provide shoes having an effective impact mitigation function.

[0016] Therefore, the present invention is especially suitable for running and jogging shoes where anti-slip properties are required. Extremely practical for not only shoes but also various sports shoes worn outdoors and indoors. It has a high sole.
