RELATED U.S. APPLICATIONS

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

FIELD OF THE INVENTION
The present invention relates generally to a roller skate, and more particularly to a roller skate which is provided with a shock-absorbing device to mitigate the transmission of shock wave from the roller skate to the head of a person who glides on a hardwood floor, sidewalk, and the like.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, the conventional roller skate comprises a boot
10
, a sole plate
11
, and a plurality of wheels
12
which are pivotally fastened to the sole plate
11
. The sole plate
11
is fastened to the outsole of the boot
10
. When a person wears the conventional roller skates to glide on a hard surface, the shock wave is easily transmitted to the boot
10
from the wheels
12
. This is due to the fact that the conventional roller skate is devoid of a shock-absorbing device. The shock wave is often transmitted to the head of a wearer of the conventional roller skate. In other words, the wearer of the conventional roller skate can feel the mechanical friction between the wheels
12
and the surface on which the wheels
12
glide. As a result, it is rather uncomfortable for a person to wear the conventional roller skate to glide on a hard surface.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a roller skate with a shock-absorbing device, so as to make the roller skating a comfortable and pleasant sport.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a roller skate comprising a boot, a wheel frame, a connection frame located between the boot and the wheel frame, an expandable frame fitted around the connection frame, and an elastic member disposed in the connection frame to serve as a shock-absorbing device to prevent the transmission of shock wave from the wheels to the boot.
