Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a shoe spike for shoes applied to sports shoes such as golf shoes, anti-slip shoes for cold regions, and the like.
[0002]
[Prior art]
Various types of shoe spikes have been developed to prevent various sports shoes from slipping and to prevent slipping on cold snow surfaces.
For example, many types of golf shoes are commercially available, such as metal spikes and synthetic resin spikes called soft spikes.
[0003]
The basic configuration of a shoe spike is a shoe having a number of hard spike pins (heels) protruding from the sole.
[0004]
The spike pin is installed by embedding the root itself of the spike pin directly in the sole and planting it, and inserting the spike pin (embedded seat) into the shoe sole and making this insert a separate part. There is a configuration in which a threaded spike pin is screwed together.
[0005]
Spike pins have various protrusions and shapes.For example, when walking on a paved road, the protrusions are adjusted to suppress walking noise, and golf shoes are not so sharp because they do not damage the green grass. Cylindrical synthetic resin soft spikes have been developed and are widely used.
[0006]
[Problems to be solved by the invention]
As you can see, there are a wide variety of shoe spikes, but a common problem is that foreign matter such as dirt, mud, turf, and grass dust adheres around the pin, and eventually it becomes dango-like and it takes time and effort to drop it There is a problem that it takes.
FIG. 6 shows a state in which foreign matter adheres to a soft spike attached to a conventional golf shoe, and even though it is difficult to adhere due to the material and shape, it will solidify in a dango shape sometime. For example, as shown in FIG. 5, a professional golfer is forced to drop mud or the like with a tee or a mark repair in order to always make a solid scaffold.
The problem to be solved by the present invention is to reduce the adhesion of foreign matter by dropping the foreign matter attached around the spike pin during walking.
[0007]
[Means for Solving the Problems]
The present invention includes an insert 1 with a female screw 10 embedded in a shoe sole 4 and a receiving plate 3 with a male screw 31 that rotatably supports a spike pin 2 that is screwed onto the insert 1 and is exchangeably attached. Then, the spike pin 2 is rotated by a walking load and the adhering foreign matter around it is dropped to propose a spike for shoes corresponding to the above problem.
The receiving plate 3 has a cylindrical portion 32 having a center hole 30, and the spike pin 2 and the center hole 30 are configured to support the spike pin 2 so as not to move up and down and to rotate freely. .
[0008]
Specifically, a circular recess 35 having a large diameter is formed at the lower end opening edge of the center hole 30 of the receiving plate 3 and the upper end opening edge is formed as a trumpet-shaped opening 36, while the spike pin 2 is disposed in the middle of the shaft portion 20. A small disk portion 21 that fits into the circular concave portion 35 is provided, a circular hole 22 is provided at the upper end portion of the shaft portion 20, and the circular hole 22 is expanded after the spike pin 2 is loaded in the center hole 30 of the receiving plate 3. The spike pin 2 is engaged with the trumpet-shaped opening 36 so as not to move up and down and to be supported rotatably.
The tip shape of the spike pin 2 is a square shape such as a circle or a rectangle.
The structure of the present invention can be applied not only to the metal spikes shown in FIGS. 3 and 4, but also to the soft spikes of golf shoes if the receiving plate 3 is partially covered with a synthetic resin spike cover 5. In addition, if the design of the protrusion of the spike pin 2 is changed, it can be applied as an anti-slip shoe for cold regions.
Design changes such as the shape, thickness, and length of the spike pin 2 according to the type of sports and the usage environment are expected by the present invention.
[0009]
DETAILED DESCRIPTION OF THE INVENTION

[0011]
FIG. 5 is a perspective view showing an action of removing mud and the like adhering to a conventional shoe, and FIG. 6 is a cross-sectional view showing a state in which foreign matter adheres to a conventional soft spike.
[0012]
The embodiment of the present invention shown in FIGS. 1 to 4 will be described. First, as components, an insert 1 embedded in a shoe sole 4, a receiving plate 3 for rotatably supporting a spike pin 2, and a synthetic resin And the spike cover 5.
The insert 1 is assembled by rotatably supporting the spike pin 2 and screwing the receiving plate 3 covered with the spike cover 5.
[0013]
The insert 1 with the internal thread 10 is embedded in a shoe sole 4 molded with a resin such as a urethane resin material, and is made with a material strength corresponding to a twist of a foot or a ring-shaped stress. In the embodiment, it is made of an aluminum alloy. Thus, a circular upper plate 13 having a diameter larger than that of the cylindrical portion 12 is provided on the upper surface of the cylindrical portion 12 having a downward hole 11 provided with an internal thread 10 on the inner surface. A plurality of holes 14 into which the molding resin to become is provided.
The insert 1 with the female thread 10 is embedded in the resin of the shoe sole 4 with a hole 11, and has a structural and mounting strength sufficient to cope with a load such as rotation and twist applied to the shoe sole 4. Is requested.
In the embodiment, the resin that forms the sole 4 is integrated into the hole 14 of the circular upper plate 13 and is integrated. However, the upper plate 13 is thickened or broken by providing a blade or a rib. It is also the expectation of the present invention that no cracks or cracks occur.
The upper plate 13 is an example of a circle, but it is naturally possible to immobilize it in the sole 4 by making it square or the like in plan view.
[0014]
An insert 1 with a female screw 10 is attached with a spike pin 2 and a receiving plate 3 with a male screw 31 that rotatably supports the spike pin 2.
The receiving plate 3 is provided with a central hole 30 and is provided with a cylindrical portion 32 having an external thread 31 on the outer surface. The cylindrical portion 32 is provided with a flange portion 33 extending outwardly therefrom, and is attached to the flange portion 33. A pair of holes 34 for the removal tool is provided.
The center hole 30 of the receiving plate 3 is a rotatably supported spike pin 2 which will be described later, and is processed to fit the outer diameter contour of the spike pin 2 very precisely, leaving only a gap of 0.05 mm or less. Created with exact dimensions to load.
The shape of the center hole 30 is a shape that holds the spike pin 2 in a configuration in which the spike pin 2 does not move up and down and rotates with a uniform and fine gap.
In the embodiment, a circular recess 35 having a large diameter is formed on the lower surface of the cylindrical portion 32, a center hole 30 is formed from the center thereof, and a trumpet-shaped opening 36 that is wide open and curved in the upper portion is formed. Yes.
Since the concave portion 35 having a large diameter is formed at the lower end opening edge of the center hole 30 and the upper end opening edge is widened, the spike pin 2 loaded therein can be supported so as not to come out in subsequent processing.
[0015]
The spike pin 2 is made of hard metal or ceramic and has a tip or a pyramid shape, and a small disk portion 21 that fits into the circular recess 35 of the receiving plate 3 is provided in the middle of the shaft portion 20. A circular hole 22 is provided at the upper end of 20.
The shape of the tip of the spike pin 2 is important, and the rotation rate can be changed depending on the shape.
The upper end portion of the shaft portion 20 of the spike pin 2 is pushed and widened to match the shape of the upper end opening of the cylindrical portion 32 of the receiving plate 3 and deformed into a trumpet-like portion 23 so that it does not move up and down and does not come out.
The spike pin 2 is attached to the bearing central hole 30 of the cylindrical portion 32 by a small disk portion 2 on the lower side and a large trumpet-like portion 23 that is pushed upward to be rotatably supported without coming out. .
Since the spike pin 2 is held in the center hole 30 of the receiving plate 3 with a fine gap, water and dust do not enter and rotate smoothly. Of course, if lubricating oil is injected into the gap, the rotation will be smoother, but it will turn so smoothly that the necessity will not be felt.
[0016]
In this way, the spike for shoes comprising the receiving plate 3 with the male screw 31 that rotatably supports the spike pin 2 that is screwed onto the insert 1 with the female screw 10 is a female screw embedded in the shoe sole 4. The spike pin 2 can be exchangeably attached to the insert 1 with 10 and the attached spike pin 2 is characterized by being rotated by a load caused by walking.
[0017]
The spike pin 2 is firmly stabbed into the ground because the vertical axis position is firmly fixed only by rotating.
The spike pin 2 rotates due to relative actions such as walking, weight load from above, and inclination of the ground.
When a person puts on the spike pin 2, a genuine non-perpendicular force acts on the spike pin 2 and a rotational force is applied by the force.
In particular, if foreign matter 6 such as mud, turf, or grass adheres, the spike pin 2 rotates little by little in the following operation.
This rotation is sufficient to remove the foreign matter 6 such as mud adhering to the periphery of the spike pin 2, and the foreign matter 6 is peeled off by the rotation.
The foreign matter 6 does not accumulate and does not become a dango.
[0018]
The spike for shoes of FIG.1 and FIG.2 has shown what covered a part of receiving plate 3 with the external thread 31 which supports the spike pin 2 rotatably with the plastic spike cover 5 which has the nail | claw part 51. FIG. .
FIG. 1 is an exploded view of each component before assembly. Actually, as shown in FIG. 2, the receiving plate 3 is covered with a brim 33 by a spike cover 5 and a synthetic resin is formed around the spike pin 2. The claw portion 51 is erected to make it difficult to damage the green grass.
It is configured as a so-called soft spike.
The shape of the spike cover 5 and the height of the claw portion 51 can be variously changed. The illustrated spike cover 5 is provided with four claw portions 51, four small protrusions 52 provided therein, and a hole 53 for an exchange tool.
[0019]
The receiving plate 3 with the male screw 31 that rotatably supports the spike pin 2 may be attached to the shoe sole 4 as it is as shown in FIGS.
3 and 4 are so-called metal spikes. The spike pin 2 sticks firmly into the ground as before, has grip, and the spike pin 2 rotates, so that foreign matter does not adhere easily. It is easy to peel off, and even if it adheres, the foreign matter will drop off naturally, making it a spike for shoes that can maintain a stable grip.
[0020]
【Example】
As an example, an insert 1 and a receiving plate 3 that rotatably supports the spike pin 2 were made of an aluminum material.
In the insert 1, the upper plate 13 has a diameter of 20 mm, and the height of the cylindrical portion 12 is 8 mm. After the spike pin 2 was loaded into the center hole 30 of the receiving plate 3, the upper end of the spike pin 2 was spread out in a trumpet shape with a punch and supported rotatably.
The shoe spike according to the present invention was attached to one shoe sole 4 and one shoe sole was fitted with a conventional spike, and a golf round was tried, but the spike of the present invention needs to be mud removed. There was no such thing.
[0021]
【The invention's effect】
As described above, the present invention naturally imparts rotation to the spike pin without deteriorating the grip property, makes it difficult for foreign matter to adhere to the periphery and naturally falls off, and is used in various sports and cold districts. It is very useful as a shoe spike for anti-slip.
