Abstract

PROBLEM TO BE SOLVED: To provide a roller skate which can absorb vibration from the non-flat road when rolling and can reduce centrifugal force at a curve, and which is assembled from a small number of components and has a simple construction. SOLUTION: In the roller skate, a front wheel and a rear wheel are rotatably supported on the opposite ends of a skate board itself, respectively, while the interval between the front wheel and the rear wheel is made larger than the length of a skate shoe, and the thickness of the skate board is made thinner with the distance from the heel part of the skate shoe toward the opposite ends of the skate board, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roller skate having a skating shoe at an upper portion and wheels at both front and rear ends.

[0002]

2. Description of the Related Art In a conventional roller skate generally used, a rigid slide plate for adjusting a length is provided on a roller seat which is located almost directly below a user's skating shoe body.
Since the user's skate shoe body is configured to be placed on the plate body, the vibration caused by the uneven road surface during traveling gives an impact to the user's shoe sole. For this reason, the user may feel uncomfortable, and the center of gravity may become unstable due to the centrifugal force acting on the curve during running.

[0003] In order to solve this problem, in "Curved Roller Series Roller Skates" described in Utility Model Publication No. 389113 of the Republic of China, roller frames are provided before and after the skating shoe body, respectively. Since the roller plate fixed to the bottom of the skate shoe body with rivet pins is mounted on the front and rear roller frames, and an elastic block is provided between the upper part of the front and rear roller frames and the bottom of the skate shoe body. The elasticity of the elastic block can avoid vibration during straight running, and the front and rear roller frames can be deflected about the rivet pin as an axis to make the traveling line during curved running arcuate. As a result, stable high-speed running and quick curve running characteristics can be obtained. However, the roller skates have drawbacks in that they have many assembled parts and their structures are complicated.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned problems, the present invention is directed to a roller skate capable of absorbing vibrations on an uneven road surface during traveling and reducing centrifugal force during traveling on a curve. Another object of the present invention is to provide a roller skate having a simple structure and low production cost.

[0005]

In order to achieve the above object, a roller skate of the present invention has a skate plate, which is made of an elastic material such as a metal steel plate, wood, plastic material, glass fiber, or the like. It is formed of carbon fiber or other composite laminated materials. On the upper surface of the skate board, a skate shoe body to be attached to a user's foot is fixedly installed. Also, the front wheels on both ends of the skateboard,
It has a hole for mounting the wheel that supports the rear wheel, makes the distance between the front wheel and the rear wheel larger than the length of the heel and toe of the skate shoe body, and further increases the thickness of the skate board near the heel of the skate shoe body , And both ends are thinned. With this structure, the skateboard can be flexed between the front and rear wheels by elasticity due to the load, so that it can absorb vibrations on uneven road surfaces under load, as well as a simple structure with few assembled parts. In addition, the influence of the centrifugal force on the curve during running can be reduced.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a side view of the roller skate 1 of the present embodiment, FIG. 2 is a bottom view of FIG. 1, and FIG. 3 is a partial cross-sectional side view showing a use state of the roller skate 1 of the embodiment. The roller skate 1 has a skate plate 10, and the skate plate 10 is formed of an elastic material, for example, a metal steel plate, wood, a plastic material, glass fiber, carbon fiber, or another composite laminated material.

On the upper side of the skate board 10, a skate shoe body 20 to be mounted on a user's foot is fixedly installed. Holes 11 and 12 for mounting wheels are provided at both front and rear ends of the skate board 10.
Are respectively formed in an elliptical cylindrical shape in the vertical direction, and front wheels 15 and rear wheels 16 are pivotally supported by wheel mounting shafts 13 and 14 in these mounting holes 11 and 12, respectively. With this configuration, the distance D1 between the front wheel 15 and the rear wheel 16 in the traveling direction of the skate is formed to be larger than the length D2 of the skate shoe body 20, and the skate board 10 causes the front wheel 1
5. It is configured to bend between the rear wheels 16 by elasticity. Also, the thickness of the skate board 10 is the front wheel 15, the rear wheel 1
The maximum H is at the side near the heel of the skate shoe body 20 between the six, and from this heel portion, the thickness h is at each end.
It is formed so as to become gradually thinner toward both ends so as to be 1, h2. In the present embodiment, the skate board 10 is at the height of the mounting shafts 13 and 14, in other words, the portions of the front wheels 15 and the rear wheels 16 opposite to the road surface are the upper surfaces of the skate board 10, respectively. Since the center of gravity of the entire roller skate is low, the front wheel 15 and the rear wheel 16 can use relatively large wheels, and the feeling of acceleration increases.

[0008]

As described above, according to the present invention, the skate board made of the elastic material is configured to be gradually thinner from the heel portion of the skate shoe body to both ends thereof. As a result, it is possible to absorb the vibration from the uneven road surface during traveling and reduce the influence of the centrifugal force on the curve during traveling. Further, since the holes for mounting the front wheel and the rear wheel are provided in the skate board itself, a roller skate having a simple structure with few assembly parts and low production cost can be provided.
