Abstract

PROBLEM TO BE SOLVED: To provide a roller skate which can be adopted to an usual shoe, and can be improved on a point of an operation liability and can lessen a burden of an ankle. SOLUTION: This roller skate can be adopted to the usual shoe with a fixing toll. A roller part is placed outside a foot and a height of foot grounding point is set low. Because of this, the burden of the ankle is lessened. The roller should not reach the heel. The balance liability can be good because the roller and the heel can be touched on the ground to stop. Moreover, if the roller never reaches toe part, it becomes possible to step on to stop and the operation liability can be improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller skate, and more particularly, to a roller skate worn with shoes.

[0002]

2. Description of the Related Art Conventional roller skates and inline skates have a large distance between the ground contact surface of the foot and the ground due to the existence of rollers which are rotating parts. For this reason, the burden on the ankle is large, and in order to solve this, a method is adopted in which the ankle is fixed by a special shoe to reduce the burden on the ankle.

Conventional roller skates and in-line skates have a structure in which only the roller portion is in contact with the ground not only during running but also during stopping. For this reason, it is difficult to maintain balance due to the rotation of the rollers even at the time of stop.

In conventional roller skates and in-line skates, the driving force is obtained by stepping obliquely, attaching a reverse rotation preventing mechanism to the roller portion, or the like.

[0005]

The problem to be solved is to reduce the burden on the ankle, to be used in general shoes, and to have a mechanism that easily balances when stopped.
The objective is to provide roller skates and inline skates.

[0006]

According to the roller skate of the present invention, the position of the roller, which is a rotating part, is set outside the foot. When installing on the sole of the foot, use a small roller.
Therefore, the moment between the ankle and the load on the ankle is reduced by minimizing the distance between the bottom surface of the roller skate, which is the ground contact surface of the foot, and the ground.

In the roller skate of the present invention, the roller does not have the roller from the toe to the heel of the foot but has the roller at the heel. For this reason, the roller portion and the heel portion of the shoe are in contact with the ground when stationary, and only the roller portion is in contact with the ground when running. This makes it easier to balance when stationary.

In addition, if a mechanism is provided in which a roller is provided not below the toe but below the lateral foot arch, the toe is outside the roller, and it is possible to step on the toe, which is a natural way of walking by humans. Become.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a roller skate in which rollers are arranged in two vertical lines will be described in detail with reference to the drawings. FIG. 1 is a perspective view of one embodiment of the roller skate of the present invention. The support plates 2 and 4 are formed in parallel on both sides of the sole plate 1 supporting the shoe sole by attaching support members 3a and 3b between the support plates 2 and 4. The disk-shaped rollers 5 penetrate through the roller support shafts 7 before and after the support plates 2 and 4 so that the thickness is smaller than the support material and the lower part of the rollers projects beyond the support plates 2 and 4. Installed. The roller support shaft 7 is located higher than the bottom plate 1. Roller 5
There is a certain gap between the support members 2 and 4, and the support members 3a and 3b, and the roller 5 can rotate freely. The roller skate body is grounded by these four rollers 5. The interval between the two support plates 2 is the width of the bottom plate 1. This width is wider than the sole width of the shoe used.

Holes for passing the belts 9a and 9b are provided on both side edges of the bottom plate 1, and the belts 9a and 9b are fixed through the holes. A buckle 8 is attached to one end of the belt 9b, and the belts 9a and 9b can be arbitrarily fixed by passing the other belt 9a through the buckle 8. In the same manner, the belts 10a, 1
0b through which the belt 10
a and 10b are fixed. A buckle 11 is attached to one end of the belt 10b, and the other belt 10a is passed through the buckle 11 so that the belt 10a, 10b
Can be arbitrarily fixed.

FIG. 2 shows the positional relationship between the roller portion and the sole height. It can be seen that the height of the sole plate supporting the shoe sole from the ground is lower than the roller support shaft 7. This makes it possible to lower the foot contact height.

FIG. 3 shows the positional relationship between the shoe and the present embodiment. Because the rollers do not rest on the toes and heels of the shoe, it enables the rollers and the heels of the shoes to touch down when stopped.

The present invention is not limited to the above embodiment, and the following modifications are possible. (1) In this embodiment, when viewed from the cross section, the roller portion 5
Has a structure that does not cover the toes of the shoe. However, the roller skate of the present invention is not limited to this,
The structure in which the roller portion 5 hangs over the toe of the shoe may be used. (2) In this embodiment, the method of fixing the roller skate body and the shoes is performed by the belts 9 and 10 and the buckles 8 and 11. However, the roller skate of the present invention is not limited to this, but may be any method that can fix the roller skate body and shoes. (3) In this embodiment, the roller skate main body and the shoes are handled as separate items. However, the roller skate of the present invention is not limited to this, and the roller skate body and shoes may be integrated. (4) In this embodiment, the surface of the bottom plate 1 is not particularly processed. However, the roller skate of the present invention is not limited to this, and the surface of the sole plate 1 may be subjected to processing such as unevenness in order to reduce slippage with the shoe sole.
