made of flexible plastic.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a backpack, and more
particularly to a backpack with supporting structure.
[0003] 2. Description of the Prior Arts
[0004] As a tool for carrying objects, bags vary from the early
handmade basket and the handbag to the current plastic, Synthetic
Leather or other material made bags, including suitcase, wallet,
lady handbag, school bag, backpack and the like.
[0005] Different bags have different specialties, for example, the
shopping bag maybe not beauty in appearance but should be foldable
for easy storage, and the lady handbag is normally provided with a
support structure for protecting the objects received therein. And
most of the backpacks available on the market are soft in structure
and unable to well protect and effectively tidy up the objects
received in the bag, so that the objects are always in a mess. As
shown in FIG. 1, a conventional backpack is usually made of
flexible non-woven material and generally comprises a front part
31, a rear part 32, a bottom 33, a first side 34, a second side 35
and zips 36, 37 on the first and second sides, the first and second
sides 34 and 35 define two receiving spaces. Since it is made of
flexible material through sewing process, the backpack is not only
high in production cost, but also too soft in structure, failing to
provide strong support to the objects to be received in the bag, so
that the objects will always be in a mess.
[0006] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a backpack with supporting structure capable of providing strong
support for the objects received therein.
[0008] A backpack with supporting structure in accordance with the
present invention comprises a front part, a rear part, two opposite
sides and a plurality of partitions, wherein the two opposite sides
are connected to the front and rear parts by hot melting, each of
the two opposite sides comprises at least two a first and a second
sheet members, the partitions are disposed between the front and
rear parts to form a plurality of receiving spaces, on the two
opposite sides are arranged zips, an end of the first sheet member
is connected to a lower end of the second sheet member by hot
melting, so as to form a foldable portion that is connected to the
partitions by hot melting.
[0009] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings, which show, for purpose of illustrations
only, the preferred embodiment in accordance with the present
invention.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 shows a conventional backpack;
[0011] FIG. 2 is a perspective view of a backpack with supporting
structure in accordance with the present invention;
[0012] FIG. 3 is an exploded view of a backpack with supporting
structure in accordance with the present invention;
[0013] FIG. 4 is a cross sectional view of the backpack with
supporting structure in accordance with the present invention,
taken along the line A-A of FIG. 3;
[0014] FIG. 5 is a cross sectional view of showing the two opposite
sides and the partitions of the backpack with supporting structure
in accordance with the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] Referring to FIGS. 2 and 3, a backpack with supporting
structure in accordance with the present invention is shown and
comprises a front part 11, two opposite sides 20 and a rear part
13. The front part 11 can be provided with different pockets
according to needs, and the rear part 13 also can be provided with
belts, pockets or the like according to needs. On the two opposite
sides 20 are arranged two zips 14 and a hard plastic made partition
15 is disposed between the zips 14, defining two receiving spaces
therebetween. The two opposite sides 20, the front and rear parts
11, 13 are integrally connected to one another by hot melting, so
the assembly of the this backpack will be more time-saving than the
conventional one. The two sides 20 are made of flexible plastic in
form of a circular framework, so as to form a strong structure of
the backpack by cooperating with the hard partition 15.
[0016] The partition 15 is also integrally formed with the two
sides 20 by hot melting, each of the two sides 20 comprises two a
first and a second members 21, 22, as shown in FIG. 4, at the
connection between the first and second sheet members 21, 22 and
the zips 14 is formed an opening 27, so that the zips 14 can
protrude out of the opening 27 for easy use. An end of the first
sheet member 21 is connected to the front part 11 by hot melting,
and another end of the first sheet member 21 is located beneath the
second sheet member 22 and have a melting portion as indicated by
25 connected to the second sheet member 22 by hot melting, so as to
form a foldable portion 26 that is folded down to be melted with
the partition 15 by hot melting. And the partition 15 can be melted
at the left or right sides of the foldable portion 26.
[0017] The number of sheet members and the receiving spaces can be
varied according to needs.
[0018] While we have shown and described various embodiments in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
