Expandable Luggage
Abstract
An expandable luggage includes a luggage body, a luggage cover,
a secondary cover and an extension fabric connected between the
secondary cover and the luggage cover through second zippers. The
secondary cover has an outer flange. The luggage cover has an inner
flange. The inner flange engages with the outer flange. Thus, when
the secondary cover is extended to expand the inner space of the
luggage body, the extension fabric can be protected to prevent the
extension fabric from being damaged so that the articles in the
luggage won't be stolen.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to an expandable luggage, and
more particularly, to an expandable luggage which can expand or
reduce its size and is durable to prevent the luggage from being
damaged.
[0003] 2. Description of the Prior Art
[0004] As shown in FIG. 1 and FIG. 2, a conventional luggage can
change the size of the luggage body. The luggage comprises a
luggage body 1, a luggage cover 2 having a first zipper 3 and an
extension fabric 5 between the first zipper 3 and the luggage cover
2. Both sides of the extension fabric 5 are provided with second
zippers 4, respectively. As shown in FIG. 1, when the user wants a
small-sized luggage, the second zippers 4 are zipped to hide the
extension fabric 5 so as to shorten the distance of the luggage
body 1 and the luggage cover 2. As shown in FIG. 2, when the user
wants to expand the size of the luggage, the second zippers 4 are
unzipped to expose the extension fabric 5 so as to lengthen the
distance of the luggage body 1 and the luggage cover 2. The
foregoing structure has the following shortcomings.
[0005] 1. The extension fabric 5 is made of a soft material and its
strength is not good so the extension fabric 5 may uneven.
[0006] 2. The thief can cut the extension fabric 5 to steal the
articles in the luggage easily.
[0007] 3. Because the extension fabric 5 is soft, the luggage body
1 may be deformed.
[0008] This causes the luggage wheels to run unstably.
[0009] 4. As shown in FIG. 3, when the luggage is dragged with two
wheels and the luggage cover 2 is filled with some articles to have
a certain weight, the luggage cover 2 may slide downward to cause
deformation of the luggage.
[0010] Accordingly, the present invention intends to provide an
expandable luggage for improving the shortcomings mentioned
above.
SUMMARY OF THE INVENTION
[0011] The primary object of the present invention is to provide an
expandable luggage. The expandable luggage comprises a luggage
body, a luggage cover, a secondary cover, and an extension fabric
between the secondary cover and the luggage cover. Two sides of the
extension fabric are provided with second zippers to connect with
the luggage cover and the secondary cover. The luggage cover has an
inner flange. The secondary cover has an outer flange. The inner
flange engages with the outer flange. When the user wants to reduce
the size of the luggage, a portion of the secondary cover is
retracted in the luggage cover. When the user wants to expand the
size of the luggage, the secondary cover can be extended outward
and the extension fabric is still protected by the luggage cover to
prevent the extension fabric from being damaged and to prevent the
articles in the luggage from being stolen. The inner flange engages
with the outer flange so that the secondary cover and the luggage
cover are connected together to form a durable luggage.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Embodiments of the present invention will now be described,
by way of example only, with reference to the accompanying
drawings.
[0019] As shown in FIG. 4, FIG. 5 and FIG. 6, the present invention
comprises a luggage body 10 having a first zipper 11 and a luggage
cover 12. One side of the luggage cover 12 is provided with a
secondary cover 14. An extension fabric 20 is provided between the
secondary cover 14 and the luggage cover 12. Two sides of the
extension fabric 20 are provided with second zippers 21 to connect
with the luggage cover 12 and the secondary cover 14. The secondary
cover 14 has an outer flange 15 around a periphery thereof. The
luggage cover 12 has an inner flange 13 around a periphery thereof.
The outer flange 15 of the secondary cover 14 is mounted in the
luggage cover 12 so that the inner flange 13 of the luggage cover
12 engages with the outer flange 15 of the secondary cover 14.
[0020] According to the aforesaid structure, the functions and
effects of the present invention are descried in detail
hereinafter. As shown in FIG. 5, when the user wants to expand the
space between the luggage body 10 and the secondary cover 14, the
second zippers 21 are unzipped to extend (unfold) the extension
fabric 20 and the secondary cover 14 is extended outward from the
luggage cover 12, such that the size of the luggage is increased.
When the user wants to reduce the inner space of the luggage body
10, the secondary zippers 21 are zipped to shorten (fold) the
extension fabric 20, such that a portion of the secondary cover 14
is received in the luggage cover 12 to reduce its size.
Accordingly, the present invention has the following effects and
advantages.
[0021] 1. As shown in FIG. 5, when the size of the luggage is
expanded and the extension fabric 20 is extended, the extension
fabric 20 is still covered by the luggage cover 12 so that the
extension fabric 20 won't be damaged and the articles in the
luggage won't be stolen.
[0022] 2. As shown in FIG. 5, when the size of the luggage is
expanded and the secondary cover 14 is extended outward, the outer
flange 15 is stopped by the inner flange 13 of the luggage cover 12
to keep the connection state. Thus, the luggage is durable and
won't have the uneven problem. Besides, the luggage cover 12 and
the secondary cover 14 are connected stably. The luggage body 10
won't be deformed and the luggage wheels can run smoothly and
stably.
[0023] 3. As shown in FIG. 6, when the size of the luggage is
reduced, the secondary cover 14 is retracted in the luggage cover
12 to form a dual structure at their connecting position so as to
enhance the strength of the luggage.
[0024] Although particular embodiments of the present invention
have been described in detail for purposes of illustration, various
modifications and enhancements may be made without departing from
the spirit and scope of the present invention. Accordingly, the
present invention is not to be limited except as by the appended
claims.
