Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a shoe sole, and particularly to a shoe sole with excellent shock absorption and repulsion.

[Prior Art] In recent years, we have seen a significant increase in the number of people who engage in running and jogging as recreational sports. However, with the increase in the number of people playing sports, the use of athletic shoes that do not provide adequate shock absorption for the user's feet will lead to an increase in the number of people suffering from injuries and disabilities.

The two most important properties desired not only for athletic shoes but also for ordinary shoes are good shock absorption and flexibility, which are understood not only by those skilled in the art but also by recreational runners. is recognized. These soles must be flexible enough where the foot naturally flexes, yet strong enough to withstand impact, yet provide adequate cushioning and comfort. It must have the flexibility to provide This property of being flexible and strong at the same time is very useful for both athletic shoes and regular shoes.

Additionally, shoe soles have the ability to control the pronation (turning of the ankle inward) and supination (turning of the ankle outward) of the user's foot, as well as the ability to prevent excessive force from being applied, especially to the heel of the foot. In some cases, it may be necessary to provide local resistance.

The sole structure of most shoes on the market today is a three-layer structure consisting of an outer sole, a midsole, and an inner sole.Since the outer sole is the part that touches the ground, it is generally strong and wear-resistant. It is made of certain materials.

The midsole is a part provided between the outer sole and the inner sole, and its function is to generate a repulsive force that lifts the heel and to act as a cushion for the entire shoe. An insole is typically used to connect the insole to the shoe body.

Most shoe insoles on the market today consist of a single layer of compressible rubber-like material or the like. The force required to compress such a substance is initially very small, but if more force is applied to compress it further, a larger force becomes necessary.

Conventional shoe soles include an insole or an outsole with ribs or ridges that have at least a portion of the sole inclined with respect to the plane of the shoe. These special soles are designed to first bend when force is applied to the sole.

Contrary to compressive forces, the initial bending of a rib (or ridge) requires a significant amount of force, but the average force required to apply further force and bend the rib (or ridge) further is small.

Some shoe soles are constructed in this way, with a rib provided on the sole touching an adjacent rib at the line position of the outer sole, but in this case, the rib does not bend at first, but If further force is applied, the shoe will come into contact with the adjacent rib, so the shoe is designed to generate a compressive force that requires the wearer to apply even more force to overcome this reaction force. be.

On the other hand, if you use a material that bends when force is applied to the insole,
Although it is possible to obtain a better cushioning surface than when using a single sheet material, it is also true that there is a need to develop shoes with better cushioning properties.

The "sole" disclosed in Japanese Patent Application Laid-open No. 60-253402 includes an insole having a plurality of sets of ribs made of a material that is curved in an arched shape or convexly formed relative to each other, and a set of these ribs. are provided close to each other. With this arrangement, compression of each set of ribs occurs as they bend and then contact adjacent ribs. This arrangement of ribs can be achieved by arranging them transversely to the longitudinal axis of the shoe, parallel to the longitudinal axis, or at various angles to the longitudinal axis.

[Problems to be Solved by the Invention] Since the conventional shoe sole described above is constructed as described above, it is possible to provide a shoe sole that is light, inexpensive, has appropriate cushioning, and is extremely soft and allows uniform gait. However, not only is it not possible to control the pronation (turning of the ankle inwards) and supination (turning of the ankle outwards) of the user's foot, but also excessive force is applied, especially to the heel of the foot. In this case, there was no local resistance, so it was impossible to cope with excessive force.

Furthermore, it has not been possible to provide a method for selectively selecting an insole having a unique resistance, which is necessary when creating shoes optimal for the user or purpose of use.

Furthermore, if the thickness of the ribs is about 1/3 thinner than that of the ribs that make up the midsole, it is possible to create a shoe sole that is quite lightweight and inexpensive to manufacture; The frequent contact and non-contact between them produced an undesirable amount of noise.

Therefore, the purpose of the present invention is to provide excellent shock absorption, control the pronation (turning of the ankle inward) and supination (turning the ankle outward) of the user's foot, and prevent excessive shock absorption. When force is applied particularly to the heel of the foot, it is possible to provide a localized resistance area, and furthermore, it is possible to provide a specific resistance force that is necessary when creating shoes that are optimal for the user or the purpose of use. It is an object of the present invention to provide a method for selectively selecting an insole having an insole.

Another object is to prevent noise generation when adjacent sets of ribs frequently come into contact and non-contact with each other.

[Means for Solving the Problems] In order to solve the above-mentioned problems and achieve the objectives, the sole of the present invention has the following configuration, namely:
A shoe sole having an inner sole provided directly below the shoe, a midsole provided directly below the inner sole, and an outer sole provided directly below the midsole, the midsole comprising a plurality of parallel a set of ribs, the set of ribs comprising a first rib and a second rib, the first rib being bent toward the second rib, and the set of ribs being bent toward the second rib; , a compressible member is provided.

Further, preferably, the bridging member is provided between the parallel adjacent ribs forming the set of ribs.

Preferably, each of the second ribs is bent toward the first rib.

Preferably, the compressible bridging member is provided at an intermediate point between the first rib and the second rib forming the set of ribs.

Preferably, the compressible member substantially fills a space defined in one of the sets of ribs.

Preferably, the compressible member substantially fills each of the spaces defined by the plurality of sets of ribs.

Preferably, each set of ribs and each compressible member extend parallel to the longitudinal axis of the shoe.

Preferably, each set of ribs and each compressible member extend parallel to the longitudinal axis of the shoe.

Preferably, each of the sets of ribs and each of the compressible members extend parallel to the lateral axis of the shoe.

Preferably, each of the sets of ribs and each of the compressible members extend parallel to the lateral axis of the shoe.

Preferably, the shoe sole has an inner sole provided directly below the shoe, an inner sole provided directly below the inner sole, and an outer sole provided directly below the inner sole, the shoe sole preferably including: comprises a plurality of parallel sets of ribs, the set of ribs consisting of a first rib and a second rib, the first rib being bent away from the second rib and being compressible. A member is provided on at least one of the rib sets.

Preferably, the compressible member is a tube having an opening.

Preferably, the tubes are provided between each pair of parallel ribs.

Preferably, each of the tubes and each of the rib sets extend parallel to the longitudinal axis of the shoe.

Preferably, each of the sets of ribs and each of the tubes extend parallel to the lateral axis of the shoe.

Preferably, the length of each of the tubes is smaller than the length of the shoe.

Preferably, the length of each of the tubes is smaller than the width of the shoe.

[Operation] According to the sole of the present invention, in order to eliminate an undesirable amount of noise, the compressible bridging member compresses along the surface of the midsole, so that if not all of the sets of ribs are compressed, I am trying to set it up.

The bridging members are respectively provided between the first rib of the rib set and the adjacent ribs, and work to prevent the adjacent ribs from coming into contact with each other when force is first applied.

Furthermore, by keeping the ribs in contact with each other at their central portions, it is possible to delay the movement of the ribs from falling diagonally with respect to the sole surface of the shoe, thereby providing stability for the foot. Furthermore, since this bridging member starts compressing from the first step of the foot, the synergistic action of the muscles caused by the warping and compression acts on the entire process of foot movement.

Other objects and many utilities of the invention will be further described in the following examples with reference to the drawings.

[Examples] Below, preferred embodiments to which the present invention is applied will be described based on the drawings.

Figures 1 to 6 show how excessive force can be applied, especially when the heel of the foot is In order to provide a local resistance portion when the ribs are applied to a portion, an example of a configuration is shown in which an elastomer plug is provided in the space of one set of adjacent ribs or a plurality of sets of ribs.

FIG. 1 is a bottom view of the sole, that is, a partially cutaway bottom view showing the appearance from the outer sole 16 side.

In FIG. 1, tube 80 is positioned between ribs 18 provided across the width of the shoe. This tube 80 could be similar in length to the full width of the shoe, but as illustrated in FIG.
It may also be partially provided between the ribs. Furthermore, as shown in the figure, the tube 8o may not be provided on all of the rib sets, and the overall length and placement position of the tube may be determined in consideration of the user's physical strength and usage method.

FIG. 4 is a partially cut away bottom view illustrating another bottom view of the sole, in which an elastomeric insert is shown between the ribs 50, 52 disposed along the longitudinal axis of the shoe. A tube 82 is provided. Similar to the configuration shown in FIG. 1, the tubes 82 do not need to be provided on every set of ribs, nor do they need to span the entire length of the ribs.

2 and 3 are partially cutaway views illustrating the shoe body 10 provided with a sole having a tube 82. FIG. FIG. 2 shows a state in which no force is applied, and FIG. 3 shows a state in which force is applied, and the tube 82 has the flexibility to deform as shown.

Here, as mentioned above, the total length of the inserted tube 82 does not have to be exact, but satisfactory results were obtained when the total length was set to 25.4 mm, for example. Additionally, the wall thickness of the tube may be selected to accommodate various athletic events, weight distributions, and user weight distributions.

It is also possible to insert a solid stopper instead of the tube described above. The stopper may be made of sponge or similar material, while the tube may include an opening to allow air to freely enter and exit the tube.

These tubes or plugs can be inserted between the set of ribs on the midsole during the manufacturing process and then secured in place using glue or other adhesives. It is also possible for the user to insert the body or tube between the ribs with his or her own hands. The tube or plug is thus attached to the ribs so that frictional forces can keep the insole or outsole in place.

Therefore, the number of tubes or plugs to be used, insertion location, overall length, and physical characteristics are selected depending on the purpose of use.

FIG. 5 is a partially cutaway view showing another embodiment. Fifth
In the figure, a refraction preventer 94 is provided between two sets of ribs to prevent refraction. This anti-refraction body 94 is inserted between the ribs 90 and 92. This anti-refraction body 9
4 is formed of the sponge-like material used in the above-mentioned plug body, and is adapted to substantially fill the space between ribs 90 and ribs 92 as shown.

With this configuration, when force is first applied to the insole, the ribs 90 and 92 are bent to a position where they contact each other, and then the ribs are compressed in the vertical direction. here,
When the anti-refraction body 94 is inserted between the ribs 90 and 92, the refraction of the ribs is suppressed, and as a result,
A unique reaction force will be obtained. That is, by selecting various overall lengths, casting locations, and materials for the insertion member, a dedicated shoe sole with a reaction force suitable for any purpose of use can be provided. Although we have only described an example in which the ribs are provided in the longitudinal direction of the shoe, structures in which the ribs are provided in the horizontal direction can also be used.
It is possible to provide the anti-refraction body 94 described above. Furthermore, the anti-refraction body 94 can be applied to various configurations as long as it has at least one set of ribs that are adjacent to each other and in contact with each other. Furthermore, in the configuration example shown in FIG.
Although much better results have been obtained when a solid antireflector 94 is used, it is entirely possible to substitute a solid tube.

FIG. 6 is a partially cutaway view illustrating another configuration example. In FIG. 6, the midsole is provided with a plurality of sets of ribs, and each set of ribs is formed with first and second ribs. As mentioned above, when a load is applied to the midsole, the first and second ribs are bent until they come into contact with each other, but if further weight is applied in this state, the ribs of the midsole will bend. Everything will be compressed. Here, even with this configuration, the best sole is provided, but when the total thickness of the midsole is reduced from 8.46 mm to 6.35 mm, the thickness of the ribs is also reduced by the same percentage. It was found that undesirable noise was generated. It has been found that this noise occurs when adjacent ribs start contacting each other and when the contact state is released.

In FIG. 6, the problem of this noise generation is that the bridging member 98 is connected to the adjacent rib 90 and the rib 92 in FIG.
The distance can be reduced by passing it between the two as shown in the figure. This bridging member 98 can be provided between all the ribs 90 and 92, or it can be provided on most of the ribs.
The material used is a stretchable rubber-like material,
It is preferable that the material has the property of being able to deform freely and at the same time absorbing impact.

This bridging member 98 prevents the ribs 90 and 92 from coming into contact with each other, and if the ribs have not yet come into contact with each other when a vertical load is first applied, the bridging member 98 itself is compressed. , which will improve the shock absorption properties. In this way, the bending of the ribs is buffered by the bridging member 98. moreover,
As a result of the bridging member 98 serving to fix the ribs 90 and 92 as a continuous body in the horizontal direction, the ribs 90 and 92 are restrained from moving laterally, so that the pronation and supination of the foot are greatly reduced. It will be controlled.

Further, in this example, only an example in which the ribs are provided in the longitudinal direction of the shoe has been described, but the bridging member 98 can also be provided in a structure in which the ribs are provided in the horizontal direction. Further, the bridging member 98 can be applied to various configurations as long as there is at least one set of ribs that are adjacent to each other and in contact with each other. Generally, the bridging members 98 do not completely fill the spaces between adjacent ribs, but are connected to each other at the midpoints of the ribs. Furthermore, once the midsole is bent to the point where each rib of the midsole is pressed against the adjacent rib, the shape of the midsole may be different, as long as additional forces can begin to compress the ribs of the midsole. Various shapes can be used. For example, rib 18
can be spaced at various intervals and of various lengths to achieve maximum damping effect. Also,
For a particular weight, different thicknesses may be used.

Furthermore, the spacing or length of the ribs may vary depending on the type of exercise or amount of activity for which the shoe is used.

For example, as shown in FIG. 7, the width 19 of the two ribs is
It is smaller than the width 21 of another rib. Furthermore, the length of each rib can be varied by one. In the drawings mentioned above, sole shapes have been shown that have ribs that are parallel or transverse to the longitudinal axis of the sole, but what angles are these ribs to the longitudinal axis? can also be made. Furthermore, the above-mentioned tube or plug may be immovably installed between the set of ribs of the insole during the manufacturing process, or the plug or tube may be manually inserted between the ribs by the user. It is also possible.

Although the present invention has been described above with reference to specific configurations shown in the drawings, it should not be construed as limiting the scope of the present invention in such a specific sense.

[Effects of the Invention] Since the sole of the present invention is constructed as described above, it has excellent shock absorption and can control the pronation and supination of the user's foot, preventing excessive force, especially at the heel of the foot. In addition, it is possible to provide a local resistance part when added to a part, and also to selectively create an insole with a unique resistance force, which is necessary when creating shoes that are optimal for the user or purpose of use. Furthermore, there is provided a sole that can prevent noise generation when adjacent sets of ribs frequently come into contact and non-contact with each other.
