ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to a footwear, and more particularly to a footwear that is designed for use as a walking shoe as well as an article of roller skate.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, an article of prior art roller skate is provided with a sole plate
1
which is in turn provided in the front end thereof and the rear end thereof with a protruded portion
2
. A sole
3
is attached to the underside of the sole plate
1
and is provided with two receiving cells
4
corresponding in location to the protruded portions
2
of the sole plate
1
. Two roller seats
5
are provided with a roller base seat
6
, a pivoting seat
7
mounted on the roller base seat
6
, and a roller
8
mounted on the pivoting seat
7
. The two roller base seats
6
are located in the receiving cells
4
. The roller
8
can be extracted out of or retracted into the sole
3
for skating or walking. When the roller
8
is jutted out of the sole
3
, the pivoting seat
7
is in contact with the protruded portion
2
of the sole plate
1
so as to support the body weight of a wearer of the prior art roller skate.
Such a prior art roller skate as described above is defective in design in that the roller is extracted out of or retracted into the receiving cell
4
with finger, which is thus prone to become dirty. In addition, the diameter of the axle of the roller
8
is limited by the thickness of the pivoting seat
7
, thereby resulting in the incompatibility of the axle with the rollers of various sizes. Moreover, the height of the roller
8
can not be appropriately adjusted to enable the prior art roller skate to be used effectively as a walking shoe as well as a roller skate.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a footwear which can be effectively used as a walking shoe or roller skate and is free from the deficiencies of the prior art roller skate described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by an article of footwear comprising a main body, a sole attached to the bottom of the main body and provided in the underside thereof with a plurality of cells, a plurality of wheel set members which are disposed in the cells and are formed of a wheel seat, two swivel arms, a wheel, an adjustment member, and a locating member. The wheel seat is fixed with the top of the cells. The two swivel arms are fastened pivotally with the wheel seat by means of an article of pivot. The wheel is pivoted between the two swivel arms. The adjustment member is connected with one swivel arm and located at one side of the sole. The wheel can be swiveled out of or into the sole by turning the two swivel arms. The locating member is connected with other swivel arm and located at other side of the sole for locating the two swivel arms. The angle at which the swivel arms are swiveled is adjusted by the adjustment member. After the swivel arms are swiveled at a predetermined angle, the swivel arms are located by the locating member so as to locate securely the wheel which is jutted out of the sole.
The foregoing objective, features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
