[Industrial applications]

 The present invention relates to a sole of a spike shoe that can be used both for normal wear and for playing sports.

[0002]

[Prior art]

 When playing baseball, golf, or other tough sports, spiked shoes are usually used to ensure a secure footing.

Spike shoes have spikes, which are hard protrusions, provided on the sole of the shoe, and the spikes sink into the ground to fix the scaffolding, so that the shoe can exert its full strength at the first time. This is convenient.

[0004] Spikes are often formed by implanting a metal rod-like object on the sole of the shoe, but synthetic resin spikes may also be used. In some cases, synthetic resin products are manufactured integrally with the shoe sole from the beginning without being planted.

[0005]

[Problems to be solved by the device]

 By the way, spike shoes are generally changed from regular footwear just before the sport that requires them. When the play is over, switch on to the regular shoes again.

However, sometimes it is troublesome to change the shoes one by one. For example, this is the case when waiting for the next round after the end of one round of golf, or when the player has to move to change the place of the game.

Therefore, in such a case, the spike shoes often move while wearing the shoes, but since the spike shoes have a rigid body struck on the sole of the shoe, when the walking surface is like a floor in the house. Is unpleasant because it produces a loud footstep each time it walks and feels unpleasant. Furthermore, when moving a car while wearing spiked shoes when moving, the hard spikes interfere with the operation of the feet.

The present invention has been made to solve the above-mentioned drawbacks of conventional spike shoes, and provides a shoe sole that can be used both for sports and for normal walking. The purpose is to do.

【Example】

 FIG. 1 is a perspective view showing an example of a shoe sole of the spike shoe of the present invention. As shown in this figure, a predetermined number of spikes 2 are planted on the back surface of the shoe sole body 1. Then, a cushioning material 3 is attached to the spike 2 to form a shoe sole of the spike shoe. A hexagonal columnar hexagonal column portion 31 is formed at the base end portion of the cushioning material 3, and a columnar columnar column portion 32 is formed at the tip end portion thereof. The tip end of the columnar portion 32 is cut in a cross shape in plan view to form a total of four notch portions 33. A through hole 34 is provided at the intersection of these four notches 33, and the spike 2 penetrates through this through hole 34.

The spike 2 is usually made of metal, but is not limited to metal, and engineering plastic or the like having considerable rigidity may be used. The cushioning material 3 is usually made of synthetic rubber, but is not limited to synthetic rubber and natural rubber may be used.

FIG. 2 is a partially enlarged sectional view of FIG. 1, showing a portion where spikes are implanted. As shown in this figure, an insert 4 is embedded in the shoe sole body 1. The bottom of the insert 4 shown in FIG. 2 is provided with a non-circular overhanging portion 41, and this overhanging portion 41 serves to prevent the embedded insert 4 from coming off and from rotating. At the upper part of the insert 4 shown in FIG. 2, there is provided a screw hole 42 in which a female screw is screwed in the vertical direction of the same figure, and the insert 4 is made so that the female screw surface is exposed. It is embedded in the main body 1.

For embedding the insert 4 in the shoe sole body 1, a so-called integral molding method is used in which the insert 4 is previously placed in a mold when the shoe sole body 1 is molded, and then injection molding is performed. Is common. Although the insert 4 is often made of metal, the insert 4 is not particularly limited thereto, and synthetic resin having high strength (so-called engineering plastics) can also be used.

On the other hand, the spike 2 is provided with a collar portion 21 at the boundary between the screwed portion with respect to the insert 4 and the screwed portion with respect to the cushioning material 3, and the collar portion 21 is provided with a tightening hole 22. Then, a male screw is screwed on the threaded portion of the spike 2 with respect to the insert 4 to form a shoe sole fixing portion 2a, and a male screw is threaded on the threaded portion with respect to the cushioning material 3. Thus, the cushioning material fixing portion 2b is formed.

The collar portion 21 is provided with at least a pair of tightening holes 22 at point-symmetrical positions with the spike 2 interposed therebetween, and a protrusion of a predetermined tool is inserted into the tightening hole 22 and screwed. As a result, the spike 2 can be reliably and easily attached to and removed from the insert 4.

An annular body 32 a is embedded in the columnar portion 32 of the cushioning material 3. On the inner peripheral surface of the annular body 32a, a female screw that is screwed with a male screw that is screwed on the cushioning material fixing portion 2b of the spike 2 is screwed. The inner peripheral surface of the annular body 32 a, on which the female screw is screwed, forms a part of the through hole 34 of the cushioning material 3. Therefore, the cushioning material 3 is attached to the spike 2 by screwing the annular body 32a into the cushioning material fixing portion 2b of the spike 2.

A conical gap 35 is formed at the lower end of the through hole 34 portion of the cushioning material 3. A ring body 5 having a hollow inside is interposed between the gap portion 35 and the collar portion 21 of the spike 2 in a state of penetrating the spike 2. In the present embodiment, the ring body 5 is made of a plastic pipe having elasticity and is formed by rolling it into an annular shape. However, the ring body 5 is not limited to plastic and may be rubber. Further, any material such as a coil spring having elasticity and capable of forming a ring can be adopted. In addition, in this embodiment, the ring body 5 has a hollow interior, but the interior does not have to be hollow as long as it has appropriate elasticity.

The thickness of the cushioning material 3 as described above in the vertical direction in FIG. 2 is set shorter than the length of the cushioning material fixing portion 2 b of the spike 2. Therefore, when the cushioning material 3 is screwed to the cushioning material fixing portion 2b of the spike 2 and tightened to the end, the tip of the spike 2 projects from the tip of the cushioning material 3 as shown in FIG. In the state shown in FIG. 2, the ring body 5 interposed between the gap portion 35 of the cushioning material 3 and the collar portion 21 of the spike 2 is crushed and flattened, and the restoring force thereof restores the cushioning material. It is in a state where force is applied in the direction of pushing 3 up.

FIG. 3 is a plan view of FIG. As shown in this figure, when the cushioning material 3 is screwed to the spike 2, the collar portion 21 of the spike 2 is extended to the outside of the hexagonal column portion 31 of the cushioning material 3, and is attached to the collar portion 21. The tightening hole 22 provided is located outside the hexagonal column portion 31 and is exposed to the outside. The tightening holes 22 provided in these collars 21 are for inserting and operating the projections of a tightening tool (not shown) when the spike 2 is screwed into the shoe sole body 1.

Further, the peripheral portion of the hexagonal column portion 31 of the cushioning material 3 is formed so as to project outward from the columnar portion 32, and when the cushioning material 3 is screwed onto the spike 2, a spanner or the like (not shown) is used. It facilitates the use of tools.

Since the shoe sole of the spike shoe of the present invention is constructed as described above, when attaching the spike 2 to the shoe sole body 1, first, the shoe sole fixing portion 2a of the spike 2 is attached to the shoe sole body 1. The female screw of the insert 4 embedded in is screwed into the screw hole 42. Then, the protrusion of the tightening tool (not shown) is fitted into the tightening hole 22 provided in the collar portion 21 of the spike 2 and twisted in a predetermined direction to tighten the spike 2 so that the spike 2 is securely inserted through the insert 4. Is fixed to the shoe sole body 1, and the cushioning material fixing portion 2b of the spike 2 is projected from the shoe sole body 1 to the outside.

Next, the ring body 5 is fitted into the cushioning material fixing portion 2b of the spike 2 protruding from the back surface of the shoe sole body 1, and the cushioning material 3 is screwed onto the ring body 5, thereby the cushioning material 3 is attached to the spike 2. Is installed.

At this time, by using a tool such as a spanner to fit it into the hexagonal column portion 31 of the cushioning material 3 and tightening the cushioning material 3, the cushioning material 3 gradually approaches the collar portion 21 of the spike 2, The ring body 5 fitted between the gap portion 35 of the cushioning material 3 and the collar portion 21 of the spike 2 is crushed, and the hexagonal column portion 31 comes into contact with the collar portion 21. In this state, the tip of the spike 2 is projected from the tip of the cushioning material 3, and the so-called spike 2 is formed on the shoe sole body 1.

Then, conversely, when the cushioning material 3 screwed to the cushioning material fixing portion 2b of the spike 2 is loosened using a tool such as a spanner, as shown in FIG. The tip end is hidden by the tip of the cushioning material 3. In this case, the ring body 5 fitted between the cushioning material 3 and the collar portion 21 of the spike 2 is restored to its original shape by its elastic force, and the cushioning material 3 is pushed upward. By this pushing-up force, the relaxed position of the cushioning material 3 is maintained reliably.

As described above, the present invention is configured so that the screwing position of the cushioning material 3 on the spikes 2 can be freely set, so that the cushioning material 3 should be tightened when playing sports. By making the tip of the spike 2 protrude from the cushioning material 3, the tip of the spike 2 digs into the soil, and the original function of the spike can be fully exerted.

In this case, since the tip of the cushioning material 3 is provided with the notch 33 cut in a cross shape, particularly when a force is applied to the foot and a large force is applied to the tip of the spike 2, The notch 33 is opened to increase the protrusion amount of the spike 2, and the spike 2 can bite into the soil by that much, so that the scaffolding is reliably secured.

In addition, during normal wear without sports, by loosening the cushioning material 3 that is fastened to the spike 2, the tip of the spike 2 is largely hidden by the tip of the cushioning material 3, and The spike 2 is not protruding. Therefore, the spikes 2 do not directly touch the ground even during normal walking, so no loud noise is emitted even if the walking place is on an indoor floor, and the driving operation of the vehicle is sufficiently safe. be able to.

As described above, the present invention can be combined with the functions of an ordinary shoe and spike shoes with a pair of shoes as described above. Therefore, it is not necessary to change shoes frequently according to the purpose, which is extremely convenient. Further, when the cushioning material 3 is worn and becomes difficult to use, it can be replaced with a new one as needed, which is economical.

[Effect of device]

 As described above, the shoe tube of the spike tube of the present invention is embedded with an insert having a female screw threaded screw hole on the surface of the shoe sole with the screw hole exposed on the surface. A spike with a male screw is screwed into the hole, and a rubber cushioning material with a female screw is screwed into the through hole in the spike. Is set shorter than the length of the spike exposed from the sole surface. Therefore, when playing sports, tighten the cushioning material screwed to the spike until its base end stops at the sole, so that the spike is exposed from the tip of the cushioning material and the original function of the spike is exerted. You can

On the other hand, during normal wearing, if the cushioning material screwed to the spike is rotated in a direction away from the shoe sole, the tip of this cushioning material hides the tip of the spike that has been protruding up to now. , The tip of this cushioning portion is grounded with a cushioning property, and does not make a strange noise when walking and is comfortable to wear.

Further, if a collar portion is provided at the boundary between the threaded portion for the spike insert and the threaded portion for the cushioning material, and if a tightening hole is provided in this collar portion, a projection of a predetermined tool can be provided on the collar portion. The spike can be easily and reliably attached to and removed from the sole of the shoe by inserting it into the tightening hole and rotating it.In addition, an elastic ring is used as a spike between the collar and the cushioning material. If inserted in a penetrating state, the elastic force of this ring body can be used at any stage from the state where the cushioning material is loosened until it conceals the spike to the state where the cushioning material projects the tip of the spike. Also, it is possible to press the cushioning material and maintain that state stably.

In addition, both the spike and the cushioning material can be screwed to the insert embedded in the shoe sole body, so that even if they are damaged by abrasion or the like, the shoe sole body itself is not replaced. It is extremely economical because it can be dealt with by replacing only spikes or cushioning materials.
