Description
TECHNICAL FIELD
[0001] The present disclosure relates to a cleaning tool capable of
easily attaching and detaching a web.
BACKGROUND
[0002] Various kinds of cleaning tools which are used by consumers
exist. Examples of cleaning tools include sponges, mops, brooms,
brushes, and the like. In addition to such cleaning tools, many
other products have been used for a long time. To satisfy various
consumers' needs for easy use, hygiene, reduction of the risk of
injury to the user while cleaning, and the like regarding such
cleaning tools, research to improve the cleaning tools has been
consistently carried out from the past to the present.
[0003] Meanwhile, cleaning tools have various forms and functions
according to places and situations in which the cleaning tools are
used. Among these places and situations, in a place such as a
bathroom where there is a lot of moisture and thus pollutants, such
as bacteria, fungi, and the like, are frequently generated on wall
surfaces, the pollutants may be removed from the wall surfaces by
applying a detergent to a surface of a web, which can be made from,
for example, a nonwoven fabric material, and rubbing the wall
surfaces with the web. In recent years, a disposable toilet bowl
scrubber (DTBS) web, which is manufactured to release a detergent
when brought into contact with moisture or damp air without the
detergent being applied to a surface of a web, was also released
into the market. When using such a web, a user should grip the web
while wearing rubber gloves on his or her hands, or should clean
using a tool which enables the web to be attached thereto, and the
reason for that is that, when a cleaning detergent applied to the
web comes into contact with the body of the user, the cleaning
detergent may adversely affect the skin of the user that comes into
contact with the cleaning detergent.
[0004] A cleaning tool, which is configured to enable a web to be
attached thereto and to be used, generally includes a pipe type
handle to enable a user to hold the cleaning tool with his or her
hands, and is provided with an attachment part to which a web is
attachable at another portion of the cleaning tool except for the
pipe type handle. Also, a web, which is gripped at the cleaning
tool, may be contaminated when used for a long time, and thus the
contaminated web should be replaced, and for this purpose, the
attachment part may be configured to enable the web to be attached
thereto and detached therefrom.
[0005] In a typical cleaning tool using a web, a user should hold a
handle with one hand and seize a contaminated web with the other
hand when separating the contaminated web from the typical cleaning
tool to separate the contaminated web therefrom. Consequently,
there is an inconvenience in that the hands of the user are
contaminated while separating the contaminated web or that the user
should wear gloves to prevent the contamination of his or her
hands.
[0006] Also, because the cleaning tool should be configured to
include both the handle and the attachment part configured to
enable a web to be attached thereto and detached therefrom, a
structure of the cleaning tool is somewhat complicated and a
manufacturing process thereof is not simplified, causing
manufacturing costs to become unnecessarily excessive and process
time unnecessarily consumed during the manufacturing process.
SUMMARY
[0007] In accordance with one aspect of the present disclosure, a
cleaning tool capable of easily attaching and detaching a web may
be provided. The cleaning tool includes a handle configured to be
grippable by a user, a body having one side to which the handle is
pivotably connected and the other side providing an attachment
surface to and from which a web for cleaning is attachable and
detachable, and a pushing unit provided at the handle to be movable
therealong, wherein, when the web is attached to the attachment
surface, the pushing unit is movable along the handle to separate
the web from the attachment surface.
[0008] In one embodiment, the cleaning tool may further include a
rod separably connected to the handle, wherein the body is
connected to the one side of the handle and the rod is connected to
the other side of the handle.
[0009] In one embodiment, the pushing unit includes a button
provided to be pushable by a hand of the user, and a push bar
accommodated inside the handle and connected to the button, and,
when the web is attached to the attachment surface and the button
pushes the push bar, the push bar moves toward an outward side of
the handle to separate the web from the attachment surface.
[0010] In one embodiment, an insertion depression into which the
push bar is insertable is formed at the handle, and a through-hole
is formed at the body and communicates with the insertion
depression to enable the push bar to pass through the

depression is formed at the handle, and, when the push bar moves
inside the handle, the sliding guide moves along the guide
slot.
[0013] In one embodiment, the body includes a pivot restriction
part which is provided to be close to the through-hole, the pushing
unit includes a push bar latch which is formed at an end portion of
the push bar and is engageable with the pivot restriction part,
and, when the push bar latch and the pivot restriction part are
engaged with each other, pivoting of the handle is restricted.
[0014] In one embodiment, the push bar latch has a shape of a
groove which is formed to be concave from the end portion of the
push bar, and the pivot restriction part includes a protrusion
which is engageable with the push bar latch.
[0015] In one embodiment, when the handle is pivoted by a
predetermined angle that is less than 90 degrees with respect to
the body, the push bar latch enters into a state of being
engageable with the pivot restriction part.
[0016] In one embodiment, the predetermined angle is 45
degrees.
[0017] In one embodiment, the push bar is selectively locatable at
one position among a first position, a second position at which the
pivoting of the handle is restrictable, and a third position at
which, when the web is attached to the attachment surface, the push
bar passes through the through-hole to separate the web from the
body.
[0018] In one embodiment, the cleaning tool further includes one or
more first grooves formed in an inner side surface of the handle
and one or more second grooves engageable with the one or more
first grooves formed in the push bar. When the one or more first

DETAILED DESCRIPTION
[0035] Hereinafter, a concrete embodiment for implementing the
spirit of the present disclosure will be described in detail with
reference to the accompanying drawings. Here, it should be noted
that the drawings are not constantly illustrated to scale for
convenience of a description. Also, when a detailed description of
related known configurations and functions is determined to obscure
the gist of the present disclosure in the following description of
the present disclosure, the detailed description thereof will be
omitted.
[0036] FIG. 1 is a perspective view illustrating an attachment of a
web to a cleaning tool according to one embodiment of the present
disclosure.
[0037] Referring to FIG. 1, a cleaning tool 10 according to one
embodiment of the present disclosure may be used in a state in
which a web D is attached to the cleaning tool 10, and a user may
rub the web D against a portion, such as a wall surface and the
like, which requires cleaning so that cleaning may be performed by
a detergent which is applied to the web D or released therefrom.
For this purpose, the cleaning tool 10 includes a body 100 having
an attachment surface configured to enable the web D to be attached
thereto and detached therefrom, a handle 200 configured to be
grippable by the user, a pushing unit 300 configured to separate
the web D, which is attached to the attachment surface of the body
100, from the attachment surface, and a rod 400 connected to the
handle 200 at an opposite side with respect to the body 100.
[0038] Here, the web D may be configured with a member made of a
nonwoven fabric material, or with a foam including a sponge, a
disposable toilet bowl scrubber (DTBS), and the like, and it may be
used by a detergent being applied to a surface of the web D or may
be manufactured in a form in which a solid detergent is coated on
the surface thereof. Also, in the case of the web D manufactured in
a form in which the solid detergent is coated on the surface of the
web D, a cleaner ingredient may be contained in the solid
detergent, and such a cleaner ingredient may be, for example, one
among calcium carbonate, potassium carbonate, sodium carbonate,
sodium bicarbonate, and sodium metasilicate. Such a web D may be
easily attached to the cleaning tool 10 by a hook 131, which will
be described below, formed at the cleaning tool 10, and may be
easily separated from the cleaning tool 10 by a user simply pushing
the attached web D in a direction receding from the hook 131.
[0039] Hereinafter, a detailed configuration of such a cleaning
tool 10 will be described with reference to FIGS. 2 to 10. FIG. 2
is a perspective view illustrating a separation of the web D and
the rod 400 from the cleaning tool 10 of FIG. 1, FIG. 3 is a
perspective view illustrating a shape of the attachment surface of
the body 100 of FIG. 1, FIG. 4 is a lateral view illustrating a
shape of the hook 131 of FIG. 3, FIG. 5 is a perspective view of a
cross section of the handle 200 of FIG. 1, FIG. 6A is a perspective
view of an upper surface of a push bar of FIG. 1, FIG. 6B is a
perspective view of a lower surface of the push bar, FIG. 7 is a
diagram illustrating a case in which the push bar of FIG. 1 is
located at a first position, FIG. 8 is a diagram illustrating a
case in which the push bar of FIG. 1 is located at a second
position, FIG. 9 is a diagram illustrating a case in which the push
bar of FIG. 1 is located at a third position, and FIG. 10 is a
diagram for describing a procedure in which the web D gripped at
the cleaning tool 10 of FIG. 1 is separated therefrom by the
pushing unit 300.
[0040] Referring to FIGS. 2 to 10, the body 100 may be configured
in a plate shape having one surface and the other surface opposite
thereto. Also, a through-hole 110 communicating with an insertion
depression 240 of the handle 200, which will be described below,
and enabling a push bar 320 to pass through the through-hole 110
may be formed at a position of the body 100 that corresponds to the
insertion depression 240. Further, such a through-hole 110 may be
formed to face the insertion depression 240. For example, the body
100 and the handle 200 may be connected to each other so that the
insertion depression 240 of the handle 200 is located at a central
portion of the body 100, and the through-hole 110 may be formed to
pass through from the one surface to the other surface of the body
100 at the central portion of the body 110. A pivot restriction
part 111 may be formed around such a through-hole 110 to be
selectively engageable with a push bar latch 322. Meanwhile, in the
drawings according to the present embodiment, the pivot restriction
part 111 has been illustrated in the form of a protrusion that
protrudes from an edge of the through-hole 110 and a recess formed
at a central portion of the protrusion, but the pivot restriction
part 111 may be modified and implemented in another form. For
example, the edge of the through-hole 110 may serve as the pivot
restriction part 111, and alternatively, only the protrusion may be
formed at the edge of the through-hole 110 to serve as the pivot
restriction part 111.
[0041] A hinge fixing part 120 configured to fix a hinge 220 of the
handle 200 may be provided at the one surface of the body 100.
Also, the attachment surface to and from which the web D is
attached and detached is formed at a surface opposite that to which
the handle 200 of the body 100 is connected.
[0042] The attachment surface of the body 100 may include a hook
existing region 130 provided with the hook 131, which is provided
to enable the web D to be attached to the attachment surface, and a
hook absent region 140 not provided with the hook 131. The
through-hole 110 may be formed at the center of the hook absent
region 140, and the hook absent region 140 may be formed to extend
in one direction centering on such a through-hole 110. The hook
existing region 130 may be formed at both sides of the hook absent
region 140, and particularly, the hook existing region 130 may be
symmetrically formed centering on the hook absent region 140. Also,
the hook existing region 130 and the hook absent region 140 may be
provided to have a predetermined ratio of area, and, for example,
they may be provided to have a ratio of 1:3. However, the spirit of
the present disclosure is not limited thereto, and a ratio of an
area between the hook existing region 130 and the hook absent
region 140 may be freely modified and implemented without departing
from the spirit of the present disclosure.
[0043] As is described above, the attachment surface may be divided
into the hook existing region 130 and the hook absent region 140 so
that a portion to which the web D is attached may be limited to
some portion of the attachment surface. Consequently, the pushing
unit 300 may be used to facilitate the separation of the web D from
the cleaning tool 10. Although a case in which the hook absent
region 140 is provided at the attachment surface of the body 100
has been exemplified and described in the present embodiment, in
some cases, the attachment surface may be modified and implemented
so that the hook 131 is formed across the entirety of the
attachment surface, and in this case, the separation of the web D
may be somewhat difficult, and adhesion thereof may be strengthened
by as much as the separation of the web D is made difficult.
[0044] Also, the hook 131 may have a shape such as a wedge, and, as
one example, the hook 131 may be configured with a head portion
1311 and a pillar portion 1312 connected thereto. At this point,
the head portion 1311 is configured with an upper surface having a
rounded shape and a lower surface which is connected to the pillar
portion 1312 and has an area that is greater than that of a jointed
surface of the pillar portion 1312 so that the upper surface of the
head portion 1311 may dig into a surface of the web D and then may
be hooked to the surface to grip the web D. Also, an edge of the
head portion 1311 is formed to have an appropriate area from the
pillar portion 1312 rather than to have an excessively wide area
therefrom so that an excessive force may not be required when
separating the web D attached to the hook 131.
[0045] The handle 200 may be rotatably connected to the body 100.
For example, the handle 200 may be configured to be pivoted in both
directions with respect to the body 100. Also, the handle 200 may
include a column part 210 extending in one direction and the hinge
220 configured to be connected to the body 100. Such a hinge 220
may be provided at one end part 201 of the handle 200, and may be
diagonally disposed with respect to the one direction in which the
column part 210 extends. For example, the hinge 220 and the column
part 210 may be disposed to form an angle of 90 degrees
therebetween, and particularly, they may be disposed to configure a
"T" shape. The handle 200 may be pivoted and rotated through such a
hinge 220. Also, the rod 400 may be connected to the other end part
202 of the handle 200.
[0046] An insert molding part 230 made of a rubber material may be
formed at some portion of a surface of the handle 200. As one
example, the insert molding part 230, which is made of a rubber
material and is applied to the handle 200, may be formed at a
surface portion of the handle 200 that is gripped with a hand of a
user, and particularly, it may be formed at the other end part 202
of the handle 200. The hand of the user may be prevented from
sliding while cleaning by such an insert molding part 230 being
made of a rubber material, and various colors and patterns may be
applied to a product due to a characteristic of an insert molding
technique to improve an aesthetic appearance of the product.
[0047] The insertion depression 240, into which the push bar 320
configuring the pushing unit 300 is insertable, may be formed at
the column part 210 of the handle 200, and the insertion depression
240 may be formed to be concave along a length direction of the
column part 210. Such an insertion depression 240 may be formed at
a side of the handle 200, which is connected to the body 100. Also,
a guide slot 250 may be formed to pass through an outward side of
the column part 210 at a circumferential surface of the handle 200
to communicate with the insertion depression 240. Such a guide slot
250 may be formed at the column part 210 of the handle 200, and,
similar to the insertion depression 240, the guide slot 250 may be
formed to be concave along the length direction of the column part
210. Also, the guide slot 250 may be formed to have a width that is
less than that of the insertion depression 240. Such a guide slot
250 may guide a sliding guide 321 which is formed at one surface of
the push bar 320.
[0048] A first groove 270 may be formed in the insertion depression
240 corresponding to an inner side surface of the handle 200. Such
a first groove 270 may be engaged with a second groove 323 which is
formed at the push bar 320. Meanwhile, in the drawings according to
the present embodiment, the first groove 270 has been illustrated
as being formed as a single protrusion, but the first groove 270 is
not limited thereto and may be freely modified and implemented in
another form. For example, the first groove 270 may be formed as a
plurality of recesses and the second groove 323 may be formed as a
plurality of protrusions so that the plurality of recesses and the
plurality of protrusions may be respectively engaged with each
other.
[0049] The pushing unit 300 is configured to be movable along the
handle 200 and moves along a length direction of the handle 200
toward the outward side thereof so that the web D may be separated
from the attachment surface of the body 100. Also, the pushing unit
300 may include the push bar 320 movably accommodated inside the
handle 200 and a button 310 provided to be manipulated by the hand
of the user.
[0050] A plurality of grooves may be formed to be continuous at a
surface of the button 310 in the form of a shape in which a ridge
portion and a valley portion are repeated. This is for increasing a
friction force to prevent fingers of the user from sliding by
expanding an area coming into contact with the fingers of the user
when the user pushes the button 310. However, this is merely one
example, and the shape of the button 310 may be freely modified and
implemented without departing from the spirit of the present
disclosure. Such a button 310 may be connected to the push bar 320
through the sliding guide 321.
[0051] Such a sliding guide 321 may be formed to protrude from a
central portion of one surface of the push bar 320. The sliding
guide 321 may be inserted into and guided by the guide slot 250 of
the handle 200. As the sliding guide 321 moves inside the guide
slot 250, movement of the push bar 320 may be guided. Such a guide
slot 250 is formed along the length direction of the column part
210 so that the push bar 320 may also be guided along the length
direction of the column part 210.
[0052] The push bar 320 may include a long member extending in one
direction, and the push bar latch 322 may be formed at an end
portion of such a long member toward the body 100. As the push bar
320 moves toward the outward side of the handle 200 along the
length direction of the handle 200, such a push bar latch 322 may
be selectively engaged with the pivot restriction part 111.
Although the pivot restriction part 111 has been illustrated as
being formed as a protrusion and the push bar latch 322 has been
illustrated as being formed as a recess in the drawings according
to the present embodiment, the spirit of the present disclosure is
not limited thereto. For example, the pivot restriction part 111
may be formed as a recess and the push bar latch 322 may be formed
as a protrusion.
[0053] The push bar 320 may be selectively located at one position
among a first position at which the push bar 320 is maximally
inserted into the handle 200 and does not restrict the rotation of
the handle 200 (See, FIG. 7), a second position at which the push
bar 320 is slightly slid and moved toward the outward side of the
handle 200 to such an extent as to enable the push bar latch 322
and the pivot restriction part 111 to be engaged with each other
(See, FIG. 8), and a third position at which the push bar 320
passes through the through-hole 110 to separate the web D from the
body 100 (See, FIG. 9). Such a first position may be a state in
which the push bar 320 is maximally pushed and inserted into the
insertion depression 240. In this case, the push bar latch 322 and
the pivot restriction part 111 are spaced apart from each other so
that the rotation of the body 100 with respect to the handle 200 is
not restricted. When the push bar 320 is pushed toward the outward
side of the handle 200 and thus is located at the second position
in a state in which the handle 200 is inclined by a predetermined
first angle a1 with respect to the body 100, the rotation of the
handle 200 may be restricted. Also, when the push bar 320 is pushed
toward the outward side of the handle 200 in a state in which the
handle 200 is inclined by a predetermined second angle a2 with
respect to the body 100, the push bar 320 pushes the web D so that
the web D may be separated from the attachment surface of the body
100. Each of the first angle a1 and the second angle a2 indicates
an angle that does not exceed 90 degrees and is one angle among
angles formed such that the handle 200 is inclined with respect to
the body 100. Also, the first angle a1 may be formed to be smaller
than the second angle a2, and, for example, the first angle a1 may
be 45 degrees and the second angle a2 may be 90 degrees.
[0054] One or more second grooves 323 may be formed in the push bar
320, and may be engaged with the first groove 270 formed in the
handle 200. As is described above, the one or more second grooves
323 may be provided. For example, the second groove 323 may be
configured with a first recess 324, a second recess 325, and a
third recess 326, and such first to third recesses 324, 325, and
326 may be disposed in parallel with each other along the length
direction of the column part 210 from an outward side of the push
bar 320 toward an inward side thereof. In other words, such first
to third recesses 324, 325, and 326 may be disposed along a
direction that is the same as that in which the push bar 320 moves.
For example, the third recess 326 may be formed to be disposed
closest to the other end part 202 of the handle 200, the first
recess 324 may be formed to be disposed farthest away from the
other end part 202 thereof, and the second recess 325 may be formed
between the first recess 324 and the third recess 326.
[0055] As is described above, when a plurality of second grooves
323 are formed, the first groove 270 may be selectively engaged
with one among the first recess 324, the second recess 325, and the
third recess 326. For example, the first recess 324 and a
protrusion of the first groove 270 may be engaged with each other
when the push bar 320 is located at the first position, the second
recess 325 and the protrusion may be engaged with each other when
the push bar 320 is located at the second position, and the third
recess 326 and the protrusion may be engaged with each other when
the push bar 320 is located at the third position.
[0056] When the handle 200 is inclined by the predetermined first
angle a1 with respect to the body 100 and the second recess 325 and
the protrusion of the first groove 270 are engaged with each other,
the push bar latch 322 and the pivot restriction part 111 are
engaged with each other such that the rotation of the handle 200
may be restricted. Also, when the handle 200 is inclined by the
predetermined second angle a2 with respect to the body 100 and the
third recess 326 and the protrusion of the first groove 270 are
engaged with each other, the push bar 320 is pushed toward the
outward side of the handle 200 so that the web D may be separated
from the attachment surface of the body 100 by the push bar
320.
[0057] Meanwhile, in the drawings according to the present
embodiment, the second groove 323 has been illustrated as being
configured with a plurality of recesses, but the second groove 323
is not limited thereto and may be freely modified and implemented
in another form. For example, the second groove 323 may be
configured with a single recess and the first groove 270 may be
configured with a plurality of protrusions so that the single
recess may be selectively engaged with one among the plurality of
protrusions.
[0058] The rod 400 may be selectively connected to the other end
part 202 of the handle 200, which is an end part opposing one side
of the handle 200 connected to the body 100. For the purpose of
such a connection, a click protrusion and a click depression may be
respectively formed at the rod 400 and the handle 200. For example,
a click protrusion 410 may be formed at the rod 400, and a click
depression 261 into which the click protrusion 410 is insertable
may be formed at the handle 200. Also, a rod connection depression
260, which is formed to be concave along the length direction of
the column part 210, may be formed at the other end part 202 of the
handle 200. When the handle 200 and the rod 400 are connected to
each other, a portion of the rod 400 at which the click protrusion
410 is formed is inserted into the rod connection depression 260,
and thus the click protrusion 410 may be engaged with the click
depression 261. Also, such a rod connection depression 260 may be
configured to communicate with the insertion depression 240. Such a
rod 400 may be used by being selectively coupled to the handle 200
according to convenience of the user. In other words, the user may
use the cleaning tool 10 by gripping the handle 200 in a state in
which the rod 400 is separated from the handle 200 or by gripping
the rod 400 in a state in which the rod 400 is coupled to the
handle 200.
[0059] Hereinafter, an operation and an effect of the cleaning tool
10 having the above described configuration will be described.
[0060] A user may use the cleaning tool 10 by locating the push bar
320 at the first position or the second position and coupling the
web D to the attachment surface of the body 100. Also, the user may
clean while freely pivoting the handle 200 with respect to the body
100 by locating the push bar 320 at the first position, and may
further clean in a state in which the pivoting of the handle 200 is
restricted with respect to the body 100 by locating the push bar
320 at the second position in a state in which the handle 200 is
pivoted by a predetermined angle, and thus engaging the pivot
restriction part 111 and the push bar latch 322 with each
other.
[0061] The user may selectively locate the push bar 320 at the
first position or the second position by moving the push bar 320
along the length direction of the column part 210 using the button
310. For example, the user may freely pivot and use the handle 200
by locating the push bar 320 at the first position. Also, the user
may use the cleaning tool 10 in a state in which the pivoting of
the handle 200 is restricted by pushing the push bar 320 toward the
outward side of the handle 200 in a state in which the handle 200
is inclined by the predetermined first angle a1 with respect to the
body 100 and locating the push bar 320 at the second position.
[0062] Meanwhile, since the web D becomes more and more
contaminated as cleaning using the cleaning tool 10 is repeated,
the contaminated web D, which is seriously contaminated and thus
cannot be used for anymore cleaning, should be replaced. For this
purpose, the web D should first be separated from the cleaning tool
10.
[0063] When separating the web D from the body 100, the user first
locates the push bar 320 at the first position to enable the handle
200 to be freely pivoted. Next, as shown in FIG. 10, the user
pivots the handle 200 by the second angle a2 and then pushes the
push bar 320 toward the outward side of the handle 200 using the
button 310 to locate the push bar 320 at the third position. At
this point, the push bar 320 passes through the through-hole 110
and one end portion of the push bar 320 pushes the web D so that
the web D may be separated from the body 100.
[0064] In accordance with the above described cleaning tool 10
according to one embodiment of the present disclosure, there is an
effect in which the contaminated web D may be easily replaced with
only an operation of pushing the button 310 by one hand of the
user.
