Description

[Detailed description of the invention] This invention relates to the improvement of spikes for sports shoes.In particular, the spikes normally protrude elastically, but retreat when they hit a hard part of the ground or the floor. This helps maintain the balance of the wearer's body and prevents scratches on the floor, etc.

Generally speaking, among sports shoes, so-called spike shoes, which have spikes on the bottom, are worn on grounds or on golf courses. When a part of the body rests on a hard part of the ground, it is easy to lose balance, and walking on hard ground can be very tiring. And especially,
When walking on the floor indoors, there are disadvantages such as damaging the floor. Such drawbacks are particularly noticeable in golf shoes. In other words, when playing golf, you walk around the course in various conditions wearing golf shoes, but at this time, for example, when you are trying to make a shot from the rough, if the shoes are stepping on pebbles, your body will not be stable. You may not be able to make a good shot, walking on hard ground when moving to another course is very tiring, and walking in the clubhouse can damage the floor.

This invention eliminates this drawback of spikes in spike shoes.

The purpose of this invention was to create a spike system that performs satisfactorily when worn in its original state, and that retreats when the shoes step on a hard surface, so that it does not interfere with comfortable walking or standing. The purpose of this invention is to provide a spike for use that does not damage the floor even when walking on a hard floor. , to provide spikes suitable for golf shoes.

That is, for example, as shown in the accompanying drawings and the embodiments described later, this invention includes a cylindrical pin holder 1, a flange 2 provided on the outer periphery of the pin holder 1, and a cylindrical pin holder 1, a flange 2 provided on the outer periphery of the cylindrical pin holder 1, and a The attachment part 3 formed on the outer periphery of the pin holder above the flange 2 is inserted into the inside of the pin holder 1 so as to be freely retractable, and the head part 4b is attached to the pin holder 1 with the tip part 4a protruding from the lower part of the pin holder 1. The pin holder 1 is locked inside.
Pin 4 is held so that it does not escape from the bottom of the
and a resilient member 5 contracted inside the pin holder 1 in order to urge the pin 4 to protrude from the lower part of the pin holder 1.

In the spike of this invention, a pin is inserted and held in a cylindrical pin holder so as to be freely advanced and retracted, and the pin is elastically projected by an elastic member.

Therefore, when you step on a hard part where the spikes don't work, the pins move back to keep your ground balance, and especially when you walk on hard surfaces or floors, you don't get tired and you don't get scratched on the floor. can be prevented from attaching.

The spike of this invention can be widely applied to so-called spike shoes in general among sports shoes, but is particularly suitable as a spike for golf shoes.

Embodiment FIG. 1 shows a longitudinal section of a spike applied to golf shoes (not shown). According to this, the pin holder 1 is made of a light and rust-resistant member such as an aluminum alloy and has a cylindrical shape as a whole. A flange 2 having a circular planar shape is integrally protruded from its lower part, and its lower end surface is
It has a gentle curve and slightly bulges in the axial direction.
Further, the upper part of the flange 2 is formed with a male threaded attachment part 3 for attachment to the bottom of the shoe. Inside the pin holder 1, there is a cylinder 1a.
A pin hole 1b having a diameter slightly smaller than the diameter of the cylinder 1a is provided at the bottom end in the coaxial direction of the cylinder 1a on the lower surface of the bottom end. It is connected so that it can be removed.

A pin 4 is inserted and held in the cylinder 1a of the pin holder 1 so as to be movable forward and backward. This pin 4 includes a head 4b that slides against the inner circumferential surface of the cylinder 1a, and a tip portion that extends from below the head 4b and slides against the inner circumferential surface of the pin hole 1b. Consisting of 4a. The head 4b is guided in alignment with the inner circumference of the cylinder 1a of the pin holder 1, and the tip 4a is guided in alignment with the inner circumference of the pin hole 1b of the pin holder 1. It protrudes outward from the bottom end.

In the cylinder 1a of the pin holder 1, an elastic member 5 is further provided in contact with the upper surface of the head 4b of the pin 4.
has been reduced. A coil spring is used here as the elastic member 5. However, the elastic member 5 is not limited to this example. Although not shown, for example, a cylindrical rubber member having relatively strong elasticity may be used.

Note that 6 in the figure is an end plate screwed onto the upper end of the cylinder 1a, and the elastic member 5 is connected to the cylinder 1a.
It is supported toward the lower end of a.

Thus, the pin 4 is biased by the elastic member 5 so that its head 4b is pushed within the cylinder 1a and its tip 4a protrudes from the lower end of the pin holder 1. At this time, since the head 4b of the pin 4 has a larger diameter than the pin hole 1b, it is supported by the inner surface of the bottom end of the cylinder 1a and prevents the entire pin 4 from escaping from the pin holder 1.

The spike configured in this way has the flange 2 attached to the bottom of the spike shoes (not shown).
The attachment part 3 is screwed in until the parts are joined.

Figures 2 and 3 illustrate the operating state of the spike of this invention.

That is, FIG. 2 shows the operating state of the spikes when, for example, one stands on a hard floor while wearing golf shoes having spikes according to this invention. It is completely retracted and does not protrude from the lower end of the pin holder 1. Therefore, most of the wearer's weight is supported by the shoe sole, which deforms and swells under pressure, and is supported only slightly by the lower end of the pin holder 1, so that it does not damage the floor.

Furthermore, FIG. 3 shows the operating state of the spikes when the user wears the spike shoes (not shown) according to the invention and stands, for example, on the ground or in the rough of a golf course. In this case, there is a pebble S in the soft ground, some of the spikes are hitting the pebble S, and at that time, the front part of the pin tip of the other spike (not shown) is completely Pin 4 of the spike is stuck in the ground.
As shown in the figure, the pebble S is stuck up to the part of the pebble S.
It retreats into the cylinder 1 against the elastic member 5 by the amount of pressure being applied. In this way, this spike can function in balance with other spikes, even when stepping on a partially hard surface.

Thus, according to this invention, the spikes of the spike shoes adapt to the hardness and softness of the ground and the degree of protrusion is naturally adjusted, so when wearing the spike shoes, you will not lose your balance or get tired. Also, walking on the floor will not cause any damage to the floor.
