Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a dust brush, and more
particularly, to a dust brush in which an advertising piece printed
with various advertising wordings, patterns, logos, or the like on
one side of a body of the dust brush is detachable to the dust
brush, and a ring formed in a rear end of the body is rotatable and
detachable.
[0003] 2. Description of the Prior Art
[0004] Generally, dust is flowed into a room, such as a home, and
is deposited on various types of furniture. Thus, this dust is
flowed into a human body when a person breathes to injure his
health. Therefore, this dust must be periodically removed.
[0005] In addition, dust is deposited on a vehicle. Thus, when the
dust is largely deposited on it, it is not good in appearance, as
well as when the dust is deposited on it, it obstructs a driver's
field of view to disturb a driver's safe drive.
[0006] For this reason, most of vehicles are essentially provided
with a dust brush.
[0007] FIG. 1 shows a dust brush, particularly, a dust brush used
for a vehicle. This dust brush 10 is configured in the form that a
brushing portion (its reference numeral is not given) made in a
form which a cloth, a piece of cloth, or the like is twisted is
detachably connected and fixed to a body 12 with a fixed length, as
shown in the figure.
[0008] In addition, the dust brush 10 is made to have a structure
in which a latch 14 is integrally formed with the end of the body
12 in order to hang it on a hook in a sidewall of the vehicle.
[0009] Therefore, when user intends to brush the dust deposited on
the vehicle, and the like, the user suffices to grip the body 12
and brush the outer surface of a vehicle body and an outer surface
of a glass with the brushing portion of the dust brush. After
using, the dust brush is put into the trunk of the vehicle or the
latch 14 of the dust brush is hanged on the hook in the sidewall of
the vehicle and then kept.
[0010] However, the dust brush, and the like as above-mentioned is
mainly used as a gift expressing the gratitude because its
manufacturing cost is relatively cheap.
[0011] That is to say, there are many cases that when a vehicle
seller presents the dust brush to a buyer as a gift, print a he/her
own name, a telephone number or a name of business office on one
side of the body of the dust brush and then present it to the buyer
for the sake of advertisement, and that also in the other business
place, for the sake of above purpose, print various advertising
wordings, patterns or logos, and the like on one side of the body
and then present it to the buyer for the sake of advertisement.
[0012] However, the dust brush as above-mentioned is that most of a
body is made from a synthetic resin. Therefore, its manufacture is
realized by an injection molding. Thus, when one intends to print
the advertising wordings, patterns or logos, a mold accordingly
should have been made.
[0013] As well known, since the mold costs a great deal in its
manufacture, it is economically inefficient to individually make
the mold in which the expensive is heavy in order to manufacture a
temporary and limited product. Accordingly, there is a problem that
the seller or the business place that intends to manufacture the
dust brush for advertisement has a large burden in view of
cost.
[0014] In addition, a latch formed in the end of the body of the
dust brush also was integrally formed by the injection molding upon
manufacturing. Therefore, when hanging the latch on the sidewall of
the vehicle, the latch is hooked only in the one direction.
SUMMARY OF THE INVENTION
[0015] The present invention is conceived to solve the
aforementioned problems, and it is an object of the present
invention to provide a dust brush that minimizes the manufacture
cost by manufacturing an advertising piece printed with various
advertising wordings, patterns or logos, and the like on one side
of a body of the dust brush, and the body to which the advertising
piece is detachable, as separate objects, respectively, and after
mass producing the body, mounting the advertising piece thus
manufactured to the body, as required.
[0016] In addition, it is a further object of the present invention
to provide a dust brush that its hanging becomes easy by
constructing such that the latch formed in the rear end of the body
can be rotated.
[0017] According to the present invention for achieving the object,
there is provided a dust brush comprising a body integrally formed
with a handle, a brushing portion which is made of a cloth or a
piece of cloth and is detachably provided with the body, and a
latch formed in a rear end of the body, comprising: a rest recess
having an engaging hole and formed on one side of the body; a
separate advertising piece in which engaging protrusions
corresponding to the engaging hole are formed to be detachable to
the rest recess of the body, and on the top surface of which
various advertising wordings, patterns or logos, and the like are
engraved; and a latch which is mounted in the rear end of the body
to be freely rotatable at 360.degree..
[0018] In addition, there is provided a dust brush further
comprising an engaging hole formed in a rear end of the body, and
gripping pieces formed on an one side of the latch and having a
little larger diameter than that of the engaging hole and can be
pursed by an elasticity, wherein the gripping piece of the latch is
forced into the engaging hole of the body and is rotatably mounted
therein.
[0019] Meanwhile, there is provided a dust brush further comprising
an engaging hole formed on one surface of the rear end of the body,
a guide piece formed with an engaging protrusion corresponding to
the engaging hole to be inserted closely to a rear end inner
surface of the body, and a separate detachable portion which the
latch is freely, rotatably mounted to its engaging hole, wherein
the latch is constructed to be detachably mounted to the body.
[0020] In addition, there is provided a dust brush, further
comprising a palm shaped gripping portion formed on a surface of
the body so as to easily grip the body when a user grips the body
using a user's own hand.

reference to the accompanying drawings in which:
[0022] FIG. 1 is a perspective view showing a conventional general
dust brush;
[0023] FIG. 2 is a perspective view showing a dust brush according
to the present invention;
[0024] FIG. 3 is a sectional view of primary parts of FIG. 2;
[0025] FIG. 4 is a perspective view showing a dust brush according

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0027] Hereinafter, preferred embodiments of the present invention
will be described in detail with reference to the accompanying
drawings.
[0028] In describing the present invention, parts identical to
those of the prior art will bear identical same reference numerals
thereto and the overlapped description thereof will be omitted.
[0029] FIG. 2 is a perspective view showing a dust brush according
to the present invention, and FIG. 3 is a sectional view of the
primary parts of FIG. 2.
[0030] As shown, the dust brush 10 of the present invention is
provided with a rest recess 24 having engaging holes 26 on one side
of its body 12.
[0031] That is to say, the body 12 is manufactured by an injection
molding in a state in which the rest recess 24 as above is formed
on its one side.
[0032] In addition, an advertising piece 20 which can be attached
and detached to and from the rest recess 24 is manufactured
separately, and this advertising piece 20 is formed with engaging
protrudes 22 for inserting and fixing to the engaging holes 26 of
the rest recess 24, and various advertising wordings, patterns or
logos are engraved on the top surface of the advertising piece, as
requirements of an orderer.
[0033] Accordingly, a manufacturer massively produces the body 12
formed with the rest recess 24 as described above and then engraves
the various advertising wordings, the patterns or the logos only on
the advertising piece 20 according to the number required by the
orderer. Therefore, it suffices to only mount the advertising piece
20 thus manufactured to the body 12 and give it to the user.
[0034] In addition, a latch 30 is rotatably mounted in the rear end
of the body 12.
[0035] That is, as shown in FIG. 3, an engaging hole with a fixed
size (its reference numeral is not given) is formed in the rear end
of the body 12, and a latch 30 is inserted and fixed into and to
this engaging hole.
[0036] That is to say, the latch 30 is formed with gripping pieces
34 having an elasticity to be pursed by a predetermined amount in
the other surface of a ring 32. Here, since a size of the gripping
pieces 34 is formed to be larger than a diameter of the engaging
hole of the body 12, the user suffices to force the gripping pieces
34 of the latch 30 into the engaging hole of the body 12.
[0037] If so do, the gripping pieces 34 of the latch 30 are pursed
under the elasticity force and then passed through the engaging
hole. Thereafter, if these gripping pieces 34 are entirely entered
into the engaging hole, they are widen by their own elasticity and
then engaged with an inner tongue portion of the engaging hole.
Consequently, the gripping pieces are fixed not to be detached
there and also the latch 30 is freely rotatable at 360.degree.
[0038] Therefore, in case of hanging the dust brush 20 on the hook
of the sidewall using the ring 32 of the latch 30, one can hang the
dust brush in a desired state by freely rotating the latch 30.
[0039] Meanwhile, FIG. 4 is a perspective view showing a dust brush
according to another embodiment of the present invention, and FIG.
5 is a sectional view of the primary parts of FIG. 4, wherein it
also is possible to detachably construct the latch 30, as shown the
figure.
[0040] That is, as in above-mentioned embodiment, if the latch 30
is forced into the rear end of the body 12, it is not easy to
detach it. Therefore, there may be a problem that the functionality
of the latch 30 is entirely lost, if the ring 32 of the latch 30 is
destructed.
[0041] Accordingly, the present embodiment forms a detachable
device 40 which is inserted into the rear end of the body 12, as a
separate object, and thus it suffices to force the gripping piece
34 of the latch 30 into the engaging hole (its reference numeral is
not given) of the detachable device 40 as in the above embodiment,
and to detach the detachable device to the rear end of the body
12.
[0042] Then, the detachable device 40 is provided with guide pieces
42 to be inserted while abutting on an inner surface of the rear
end of the body 12.
[0043] That is, an engaging hole 12a is formed on one side of a
rear end of the body 12, and an engaging protrusion 44
corresponding to the engaging hole 12a of the body 12 is formed on
one side of the guide piece 42 of the detachable device 40.
Therefore, it is possible to detachably dispose the detachable
device relative to the rear end of the body 12.
[0044] Accordingly, when a ring 32 of the latch 30 is broken so
that it cannot be used, it suffices to separately purchase only the
detachable device 40 and replace it.
[0045] In addition, a surface of the body 12 is formed with a palm
shaped gripping portion 46 so that when a user grips it using a
user's own hand, the user's hand is guided by the palm shaped
gripping portion. Thereby, the user grips it more easily.
[0046] As described above, according to the dust brush of the
present invention, there is advantage that the orderer or the
manufacturer can order or manufacture the dust brush for
advertisement or public information with a low cost, by
manufacturing the body formed with the rest recess on one side, and
separately manufacturing the advertising piece which is detachable
to the rest recess of the body, and on its top surface of which
various advertising wordings, patterns or logos, and the like are
engraved according to the orderer's order, or by manufacturing in a
state which the advertising piece is mounted to the rest recess of
the body, as required.
[0047] In addition, there is an advantage that since the latch
formed in the rear end of the body is configured to be freely
rotatable, it can easily hang the dust brush on the hook in the
sidewall of the vehicle.
[0048] Meanwhile, in case the latch is constructed to be detachable
to the body, it suffices to exchange only this broken portion on
breakage of the latch. Therefore, there also is an advantage
reducing the unnecessary expense.
[0049] Though the present invention has described with reference to
above embodiment, it is be appreciated that modifications may be
made without departing from the spirit of the present invention
