BAG WITH ADJUSTABLE STRAP
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to a bag that contains
objects therein to carry and convey them. More particularly, the
present invention relates to a bag configured such that the length
of a bag strap used to hold the bag on a user's body is easily
adjustable and an adjusted region is not exposed to the outside,
thus enabling a neat appearance to be reliably maintained and
allowing the bag to be safely used.
2. Description of the Related Art
Generally, a bag is a storage and conveyance article that is
held on a user's body by being hung over a user's shoulder or
being worn on the user's back via a strap.
Such a bag has various shapes and sizes depending on its
puLpose or user preferences. The bag basically includes a sack-
shaped main body configured to receive objects therein, and a bag
strap normally connected to the main body and held on a user's
shoulder, waist or the like.
That is, objects are received in the main body and then are
stored or conveyed by carrying the bag using the bag strap.
An opening is formed in the main body to put in or take out
objects from an internal space of the main body, which has an
opening and closing element, such as a Velcro fastener or a slide
fastener provided to open or close the opening.

The bag strap may comprise a pair of straps or a single
strap. The pair of straps extends from both ends of the main
body, respectively, to be held on and released from the body. The
single strap is configured such that both ends thereof connect to
the main body.
Moreover, the bag strap is provided with an adjusting means
for adjusting the length of the bag strap, whereby the strap can
be adjusted to a length suitable for a user's body.
As one example of the adjusting means for adjusting the
length of the bag strap, a buckle structure has been proposed.
Korean U.M. Registration No. 20-0189053, entitled Belt Device,
discloses a bag with a buckle structure that is applied to the bag
to fasten bag straps and simultaneously adjust the length thereof.
Further, Korean U.M. Publication No. 20-2012-0005148,
entitled Bag with Strap Tightener, discloses a bag with a strap
tightener, which has a back plate, side plates and bag straps to
receive objects. The bag straps are classified into a shoulder
strap secured to an upper portion of the back plate, and a waist
strap secured to a lower portion of the back plate. The length-
adjustable strap tightener connects the shoulder strap with the
waist strap. Thus, the length of each bag strap may be adjusted
by manipulating the strap tightener.

SUMMARY OF THE INVENTION
However, the conventional bag is problematic in that the
device or the structure for adjusting the bag strap is exposed to
the outside, so that an appearance is not neat and exposed regions
may be caught by surrounding objects (e.g. tree branches,
guardrails, etc.) during movement, thus threatening the safety of
the user.
Accordingly, the present invention has been made keeping in
W mind the above problems occurring in the related art, and the
present invention is intended to propose a bag, in which the length
of a bag strap used to hold the bag on a user's body is easily
adjustable and an adjusted region is not exposed to the outside,
thus enabling a neat appearance to be reliably maintained and
allowing the bag to be safely used.
In order to accomplish the above object, the present invention
is intended to propose a bag having a sack-shaped main body
configured to receive objects therein, and a bag strap normally
connected to the main body and used to hold the bag on a user's
shoulder, waist or the like, wherein a first end of the bag strap
is coupled to a first end of the main body, a wire of a
predetermined length is connected to a second end of the bag
strap, and the main body includes an adjusting means that adjusts
the length of the wire by winding or unwinding, in the state where
an end of the wire is fixed.
The adjusting means may be disposed on a region of the main
body to which the first end of the bag strap may be coupled, and
3
CA 2933227 2017-11-02
the wire may be fixedly connected to the adjusting means after
passing through an interior of the main body, via the second end
that may be symmetric with the region to which the first end of
the bag strap may be coupled, so that the length of the wire may
be adjusted in the main body.
The adjusting means may include a body secured to the main
body, with a shaft being provided on a central portion thereof; a
winding ring holding the end of the wire and rotatably secured to
the shaft of the body; and a locking member provided on the body
to stop or release the rotation of the winding ring.
As described above, the present invention provides a bag, in
which an entire length is adjusted by a wire that is adjusted in
length by an adjusting means, so that it is possible to adjust the
entire length of a bag strap as desired, and in which the length
of the wire is adjusted particularly while being located in a main
body, so that the wire is not exposed to the outside, thus always
enabling a neat appearance to be reliably maintained, and so that
the wire is not caught by surrounding protrusions such as tree
branches or guardrails, thus guaranteeing a safe use.

DESCRIPTION OF PREFERRED EMBODIMENTS
Hereinafter, a bag according to the preferred embodiment of
the present invention will be described in detail with reference
to the accompanying drawings.
The present invention may be embodied in different forms and
should not be construed as being limited to the embodiments set
forth herein. Rather, these embodiments are provided so that this
disclosure will be thorough and complete, and will fully convey
the scope of the embodiments to those skilled in the art. In the
drawings, shapes and dimensions of elements may be exaggerated for

omitted herein.
FIGS. 1 to 6 illustrate a bag according to an embodiment of
the present invention. The bag I according to the embodiment
5
CA 2933227 2017-11-02
includes a sack-shaped main body 2 configured to receive objects
therein, and a bag strap 3 normally connected to the main body 2
and used to hold the bag 1 on a user's shoulder, waist or the
like.
That is, after the objects are put into the main body 2, the
bag 1 is carried by holding it with the hand or the shoulder using
the bag strap 3.
In this respect, the main body 2 has various shapes depending
on its purpose, for example, a backpack for climbing, a school
W bag, a bag bound around the waist, etc.
In the bag 1 according to this embodiment, one end of the bag
strap 3 is connected to one end of the main body 2, with a wire 31
of a predetermined length being connected to the other end of the
bag strap 3.
The main body 2 is provided with an adjusting means 4 that
adjusts the length of the wire 31 by winding or unwinding, in the
state where an end of the wire 31 is fixed.
In other words, the entire exposed length of the bag strap 3
is adjusted by regulating a connection length of the wire 31 to
the bag strap 3 using the adjusting means 4, so that it is
possible to regulate the length of the bag strap 3 as desired.
Here, one end of the bag strap 3 may be reliably fixed to the
main body 2. It is most preferable to fasten or unfasten the bag
strap 3 to or from the main body 2 preferably using a fastening
element 32 such as a buckle or a snap fastener.
That is, one end of the bag strap 3 is fixedly connected to
the main body 2 through the wire 31, while the other end is
6
CA 2933227 2017-11-02
detachably coupled to the main body 2 through the fastening
element 32, thus allowing a more convenient use when the bag is
worn.
In the bag 1 according to the embodiment configured as such,
the adjusting means 4 is disposed on a region of the main body 2
to which one end of the bag strap 3 is coupled. The wire 31 is
fixedly connected to the adjusting means 4 after passing through
an interior of the main body 2, via the other end that is
symmetric with the region to which one end of the bag strap 3 is
coupled.
That is, the adjustment of the exposed length of the wire 31
relative to the adjusting means 4 is performed in the main body 2.
Thus, as the wire 31 is adjusted in length while being
located in the main body 2, the wire 31 is not exposed to the
outside, so that it is possible to always reliably maintain the
neat appearance
Since the wire 31 is not exposed to the outside, the wire 31
is not caught by surrounding protrusions such as tree branches or
guardrails, thus guaranteeing a safe use.
Preferably, a guide tube 22 made of fabric or elastic rubber
material is disposed in the main body 2, and has a guide hole 21
to receive and guide the wire 31 and one end of the bag strap 3.
That is, when the exposed length of the bag strap 3 is
adjusted, the bag strap 3 is rectilinearly reciprocated while
being guided in the guide tube 22.
Therefore, the bag strap 3 may keep a stable posture without
being twisted or shaken.

CA 2933227 2017-11-02
In the bag 1 according to this embodiment, the adjusting
means 4 includes a body 41 that is secured to the main body 2 and
has on a central portion thereof a shaft 411, a winding ring 42
that holds the end of the wire 31 and is rotatably secured to the
shaft 411 of the body 41, and a locking member 43 that is provided
on the body 41 to stop or release the rotation of the winding ring
42.
As the winding ring 42, which is braked by driving the
locking member 43, is rotated, the wire 31 is wound or unwound, so
that the exposed length of the wire 31 is adjusted, and
consequently the entire exposed length of the bag strap 3 is
adjusted.
In this regard, the locking member 43 is configured to lock
or unlock the winding ring 42 to or from the shaft 411. As the
locking member 43, a desired structure selected by a user is
preferably adopted, and a dial-spool structure constituting BOA
technology (Korean Trademark Registration Numbers 400729842 and
400784285) is most preferably adopted.
In the case of carrying or conveying objects using the bag 1
according to this embodiment configured as such, the objects are
first put into the main body 2 through the opening thereof, and
then the bag 1 is worn by tying the bag strap 3 to the waist or
the back using the fastening element 32.
If the bag 1 has been worn as such, the winding ring 42 of
the adjusting means 4 is rotated to wind or unwind the wire 31 and
thereby adjust its exposed length. In
this way, the entire
exposed length of the bag strap 3 is adjusted as desired, so that
8
CA 2933227 2017-11-02
it is possible to stably wear the bag 1.
In the bag 1 according to this embodiment, the exposed length
of the wire 31 is adjusted while the wire 31 is located in the
main body 2. As a result, the wire 31 is not exposed to the
outside of the main body 2, thus guaranteeing a stable use.
Although the preferred embodiments of the present invention
have been disclosed for illustrative purposes, those skilled in
the art will appreciate that various modifications, additions and
substitutions are possible, without departing from the scope and
spirit of the invention as disclosed in the accompanying claims.
