ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to luggage and more particularly to an improved mechanism for supporting/locking expandable pouch of luggage.
BACKGROUND OF THE INVENTION
A conventional expandable luggage
10
is shown in
FIGS. 1 and 2
comprising a main body
11
supported by a main frame
14
, a frame element
15
, an expandable pouch
13
coupled between main body
11
and frame element
15
, and a door panel
12
coupled to frame element
15
by a zipper. A zipper
131
is provided on expandable pouch
13
wherein the expandable pouch
13
is expanded to its maximum when zipper
131
is open and the expandable pouch
13
is retracted to its minimum when zipper
131
is closed. However, the previous design suffered from several disadvantages. In detail, the expanded expandable pouch
13
is not supported by any mechanism. As such, the bottom
132
of expandable pouch
13
may be bulged downwardly due to the weight of items packed in the luggage
10
(FIG.
2
). This may obstruct the smoothness when towing the luggage, or in an extreme case cause the damage of luggage
10
. Further, luggage
10
tends to deform after a plurality of times of use due to the bulged bottom
132
of expandable pouch
13
. Furthermore, luggage
10
may not stand upright easily due to the bulged bottom
132
of expandable pouch
13
.
SUMMARY OF THE INVENTION
It is thus an object of the present invention to provide a mechanism for supporting an expandable pouch of luggage coupled between a main body and a frame element. The support mechanism is provided at about the central portion on either side of luggage interconnected between the main frame and the frame element. With the provision of support mechanisms formed as two side supports of the expandable pouch, it is possible to prevent the packed luggage from bulging at the bottom of expandable pouch.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
