Description
BACKGROUND OF THE INVENTION
Technical Field
[0001] The present invention relates generally to a backpack, and
more particularly to a backpack with a back casing.
Description of Related Art
[0002] Backpacks for being carried on a user's back are commonly
used in outdoor activities such as walking, hiking, traveling, and
cycling. The backpack is mainly fixed to the user via straps, so
that the user could carry a heavier or a larger object in the
backpack, reducing the burden on both hands of the user. As a
result, solve the problem that the user can't carry heavy objects
for a long time by hands, and the user's hands are free to do more
activities.
[0003] Compared with other carrying bags, the backpacks have the
abovementioned advantages. However, a bag body of the backpack is
made of cloth. When the user carries the backpack, the bag body is
located behind the user, so that when the bag body is hit or pushed
from the rear, the objects inside the bag body may be damaged.
What's more, the force of the impact may hurt the user. For
instance, if a user accidentally slips, and leans their back to the
ground, the conventional backpack cannot protect the user's
back.
BRIEF SUMMARY OF THE INVENTION
[0004] In view of the above, the primary objective of the present
invention is to provide a backpack for protecting a back of a user
and objects inside of a bag body, providing various ways for the
user to use it.
[0005] The present invention provides a backpack, including a bag
body, two straps, and a back casing, wherein the bag body has an
inner surface and an outer surface opposite to the inner surface.
The inner surface is adapted to face a user's body. The straps are
engaged with the bag body. The back casing is detachably engaged
with the bag body and is located outside of the outer surface.
[0006] With the detachable back casing, the bag body and the user's
back could be effectively protected. In addition, the detachable
back casing could be detached from the bag body when the back
casing is not needed, providing a more flexible way for the user to
use it.

DETAILED DESCRIPTION OF THE INVENTION
[0020] A backpack 1 according to a first embodiment of the present
disclosure is illustrated in FIG. 1 to FIG. 4 and includes two
straps 10, a bag body 20, and a back casing 30.
[0021] The straps 10 are engaged with the bag body 20 for being
carried by a user. Only one of the straps 10 is shown in FIG. 1.
The bag body 20 has an inner surface 20a and an outer surface 20b
opposite to the inner surface 20a, wherein the inner surface 20a
faces the user's body, and the outer surface 20b faces away from
the user's body. The back casing 30 is detachably engaged with the
bag body 20 and is located outside of the outer surface 20b of the
bag body 20, wherein an inner surface 30a of the back casing 30
faces the outer surface 20b of the bag body 20. The back casing 30
is made of a hard material such as metal, plastic, wood board,
fiberglass, composite material, or a combination of the
foregoing.
[0022] More specifically, the bag body 20 has two fixing straps 40
juxtaposed from top down. In order to illustrate easily, we will
only describe the details of one of the fixing straps 40 in the
following paragraphs, for the fixing straps 40 have substantially
the same configuration. The fixing strap 40 includes a first
section 402 and a second section 404, wherein the first section 402
and the second section 404 are platy straps and are respectively
connected to two opposite sides of the bag body 20. The first
section 402 and the second section 404 are detachably connected. In
the current embodiment, the first section 402 is connected to a
first engaging member which is a first connector 42 as an example;
the second section 404 is connected to a second engaging member
which is a second connector 44 as an example, wherein the first
connector 42 and the second connector 44 are detachably engaged, so
that the first section 402 and the second section 404 could be
disengaged from each other.
[0023] The back casing 30 is in an elongated plate shape and has a
plurality of perforations penetrating through the inner surface 30a
and an outer surface 30b of the back casing 30. In the current
embodiment, the back casing 30 includes four perforations 302,
wherein each of the perforations 302 is elongated. The perforations
302 are grouped in two, and the two sets of perforations 302 are
juxtaposed from top down. Each set of perforations 302 are adapted
to be passed through by one of the fixing straps 40 to fix the back
casing 30 on the bag body 20. In the current embodiment, the back
casing 30 has two opposite side edges 30c, wherein each of the
perforations 302 is close to the corresponding side edge 30c. The
back casing 30 has a plurality of notches 304, wherein each of the
notches 304 is located between one of the side edges 30c and the
corresponding perforation 302, and communicates with the
perforations 302 and outside of the side edges 30c. The first
section 402 and the second section 404 respectively enter the
corresponding perforation 302 via the corresponding notch 304, and
then the first connector 42 and the second connector 42 could be
engaged with each other, so that the back casing 30 could be fixed
on the bag body 20. Each of the notches 304 is located between two
ends of the corresponding perforation 302, thereby to prevent the
first section 402 or the second section 404 being disengaged from
the corresponding notch 304.
[0024] In the current embodiment, the back casing 30 sequentially
has an upper section 322, a middle section 324, and a lower section
326 from top down, wherein the upper section 322 corresponds to a
top of the bag body 20, and the lower section 326 corresponds to a
bottom of the bag body 20. The notches 304 and the perforations 302
are located on the middle section 324. The upper section 322 and
the lower section 326 respectively incline in a direction from the
middle section 324 toward the outer surface 20b of the bag body 20.
In this way, the upper section 322 and the lower section 326 could
be adapted to be abutted against a top and a bottom of the backpack
1, and could not over-protrude and affect the user's
activities.
[0025] The back casing 30 has two lateral portions 342 and a middle
portion 344 located between the lateral portions 342 in a
horizontal direction, wherein the lateral portions 342 incline in a
direction from the middle portion 344 toward the side edges 30c.
The notches 304 and the perforations 302 are located on the lateral
portions 342. The middle portion 344 has a receiving groove 344a
facing the outer surface 20b of the bag body 20. In the current
embodiment, the receiving groove 344a extends from the upper
section 322 to the lower section 326. As shown in FIG. 4, after the
back casing 30 being engaged with the bag body 20, a receiving
space for receiving objects is formed between the receiving groove
344a and the outer surface 20b of the bag body 20.
[0026] By engaging the back casing 30 with the bag body 20, the
backpack 1 according to the current embodiment could not only
protect objects in the bag body 20, but also protect the user's
back. When the back casing 30 is not needed, the back casing 30
could be disengaged from the bag body 20. Other objects, such as
raincoats, sleeping mats, etc., could be placed between the back
casing 30 and the bag body 20.
[0027] However, the first engaging member and the second engaging
member are not limited to be the first connector 42 and the second
connector 44, but could be a hook fastener and a loop fastener
which could be engaged with each other, or could be a male fastener
and a female fastener which could be engaged with each other, as
long as the first section 402 could be detachably engaged with the
second section 404.
[0028] In practice, there could be only one fixing strap 40 to fix
the back casing 30 on the bag body 20. Alternatively, the bag body
20 and the back casing 30 could be respectively provided with an
engaging member to be engaged with each other. For instance, the
outer surface 20b of the bag body 20 is provided with a hook
fastener or a male fastener, and the back casing 30 is provided
with a loop fastener or a female fastener.
[0029] A back casing 50 of a backpack according to a second
embodiment of the present disclosure is illustrated in FIG. 5,
which has almost the same structure as that of the first
embodiment, except that a felt layer 52 is disposed on an inner
surface 50a of the back casing 50. In the current embodiment, the
felt layer 52 is located in a receiving groove 502, and is adapted
to be attached by a corresponding fastener 54. In this way, an
object 56 could be provided with the corresponding fastener 54,
thereby to fix the object 56 in the receiving groove 502 of the
back casing 50.
[0030] A back casing 60 of a backpack according to a third
embodiment of the present disclosure is illustrated in FIG. 6 and
FIG. 7, which has almost the same structure as that of the first
embodiment, except that a plurality of openings 602 are disposed on
the back casing 60, wherein the openings 602 penetrate through an
inner surface and an outer surface of the back casing 60. The
openings 602 are distributed in an upper section 622, a middle
section 624 and a lower section 626 of the back casing 60, and
could have the same or different sizes. In this way, the openings
602 could be adapted to be passed through by a fixing member, which
is a strap as an example, to secure an object 66 to the back casing
60. In practice, the back casing 60 could include at least one
opening 602.
[0031] A back casing 70 of a backpack according to a fourth
embodiment of the present disclosure is illustrated in FIG. 8,
which has almost the same structure as that of the first
embodiment, except that a third engaging member, which is a third
connector 72 as an example, and a fourth engaging member, which is
a fourth connector 74 as an example, are respectively connected to
two lateral sides of the back casing 70. In the current embodiment,
there are two third connectors 72 and two fourth connectors 74,
wherein the third connectors 72 are detachably engaged with the
first connectors 42 of the bag body 20 according to the first
embodiment, and the fourth connectors 74 are detachably engaged
with the second connectors 44 of the bag body 20, thereby to engage
the back casing 70 with the bag body 20.
[0032] A backpack 5 according to a fifth embodiment of the present
disclosure is illustrated in FIG. 9 to FIG. 12, which has almost
the same structure as that of the first embodiment, which also
includes a bag body 80 and a back casing 84, and the back casing 84
also has a plurality of perforations 842 for being passed through
by the fixing straps, except that the back casing 84 bulges outward
from top down, and has a recess 844 facing an outer surface of the
bag body 80, wherein the recess 844 could also receive objects.
[0033] In summary, with the back casing disposed outside of the
outer surface of the bag body, the backpack of the present
disclosure could effectively protect the bag body and the user's
back. In addition, the detachable back casing could be detached
from the bag body when the back casing is not needed, providing a
more flexible way for the user to use it.
[0034] It must be pointed out that the embodiments described above
are only some preferred embodiments of the present invention. All
equivalent structures which employ the concepts disclosed in this
specification and the appended claims should fall within the scope
of the present invention.
