RELATED U.S. APPLICATIONS

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

FIELD OF THE INVENTION
The present invention relates generally to a luggage, and more particularly to a structure for expanding capacity of the luggage.
BACKGROUND OF THE INVENTION
As illustrated in
FIG. 1
, a prior art luggage
10
is formed of a main shell
11
, a cover
12
, a zipper tape
13
, and a zipper
14
. The zipper tape
13
is fastened between the main shell
11
and the cover
12
by sewing. The capacity of the prior art luggage
10
can be expanded to an extent by unfastening the zipper tape
13
by means of the zipper
14
, thereby resulting in an increase in the capacity of the prior art luggage
10
so as to enable the luggage
10
to hold additional articles. The zipper tape
13
is not provided with a support element to prevent the cover
12
of the prior art luggage
10
from being tilted. In addition, the capacity of the prior art luggage
10
can be expanded to very limited extent. Furthermore, the external appearance of the prior art luggage
10
is affected adversely after the capacity of the prior art luggage
10
is expanded.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a luggage structure capable of expanding the capacity of the luggage without resulting in various shortcomings of the prior art luggage described above.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a luggage comprising a main shell, a cover, and an expansion fabric fastened between the main shell and the cover. The main shell is provided with two support plates, each having one or more connection members. The expansion fabric is provided with one or more locating members. As the expansion fabric is expanded to increase the capacity of the luggage, the support plates are caused to turn in the direction toward the inner side of the expansion fabric such that the connection members of the support plates are joined with the locating members of the expansion fabric, and that the expansion fabric and the cover are braced.
The features and the 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.
