Abstract:

A skate wheel structure includes a main wheel section and at least two auxiliary wheel sections at respective sides of the main wheel section. The auxiliary wheel sections are integral with the main wheel section. The outer diameter of each auxiliary wheel section is smaller than that of the main wheel section to increase contact surface with the ground so as to provide a stable rolling.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a skate wheel structure, more particularly, to a main wheel section integral with a pair of auxiliary wheel sections at respective sides of the main wheel section to increase contact surface with the ground so as to provide the stability of rolling.

2. Description of the Related Prior Art

A conventional in-line skate on the market is hard to keep balance in particular to new riders or to younger kids. An accident happens often. Sometimes kids may even get hurt.

SUMMARY OF THE INVENTION

It is the primary object of the present invention to provide a skate wheel structure, which has a main wheel section integral with a pair of auxiliary wheel sections at respective sides of the main wheel section to increase the stability of rolling.

It is another object of the present invention to provide a skate wheel structure, which is easy to learn skate skill.

It is a further object of the present invention to provide a skate wheel structure, which is easy to maintain and saves manpower.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of a first embodiment of the present invention;

FIG. 2 is a side view of the first embodiment of the present invention;

FIG. 3 is a rear view of the first embodiment of the present invention; and

FIG. 4 is a rear view of a second embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2, a first embodiment of the present invention is a rear wheel and comprises a main wheel section 1 and at least two auxiliary wheel sections 11, which is pivotally connected to a skate body 2 and incorporated with a front wheel 3 and a brake 4. The auxiliary wheel sections 11 are provided at respective sides of the main wheel section 1 and integral with the main wheel section 1. The outer diameter of each auxiliary wheel section 11 is smaller than that of the main wheel section 1.

As shown in FIG. 3, the skate of the present invention is in operation, when making a turn, one of the auxiliary wheel sections 11 and the main wheel section 1 will be encountered with the ground. This increases contact surface of the wheel with the ground, providing a better stability to the rider.

As shown in FIG. 4, a second embodiment of the present invention is still a rear wheel and comprises a main wheel 1A and two auxiliary wheels 11A, which are formed separately and then coupled together.

Claims

I claim:

1. A skate wheel structure comprising a main wheel section and at least two auxiliary wheel sections at respective sides of said main wheel section.

2. The skate wheel structure, as recited in claim 1, wherein said auxiliary wheel sections are integral with said main wheel section.

3. The skate wheel structure, as recited in claim 1, wherein each said auxiliary wheel section has an outer diameter smaller than that of said main wheel section.
