DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0030] A floor mop capable of using both sides according to the
present invention will be described hereinafter with reference to
the accompanying drawings.
[0031] FIG. 1 is a schematic view of a first embodiment of a floor
mop 100 capable of using both sides according to the present
invention. And FIG. 2 is a schematic view of a first rotation zone
20 and a supporting pad 10 of a floor mop 100 capable of using both
sides of FIG. 1. In addition, FIG. 3 is a side view of a floor mop
100 capable of using both sides of FIG. 1. Also, FIG. 4 is a
schematic view of a second rotation zone 30 and a roller 40 of a
floor mop 100 capable of using both sides of FIG. 1.
[0032] As shown in FIG. 1, FIG. 2, FIG. 3 and FIG. 4, a floor mop
100 has a rotation structure for fixing selectively both sides of a
floor cloth 90 attached to the supporting pad 10. The rotation
structure has a permanent magnet 80 to press and fix the floor
cloth 90 by a magnetic force.
[0033] Here, the rotation structure is formed of a rotation section
50, wherein the rotation section 50 has a connection structure
which comprises a first rotation zone 20 hinge-combined with the
supporting pad 10, a second rotation zone 30 hinge-combined with
the first rotation zone 20, and a roller 40 hinge-combined with the
second rotation zone 30, thereby the rotation structure is capable
of rotating smoothly around the supporting pad 10.
[0034] And velcro tape 12 is attached on the supporting pad 10 for
the exclusive floor cloth 90 being fixed thereon. Two water passage
portions 11 are penetratively formed at both sides of the
supporting pad 10 so that water of the exclusive floor cloth 90 is
fairly drained. The water passage portions 11 are symmetric with
each other and have rectangular configurations. Eight velcro tapes
12 are preferably positioned around the water passage portions 11
at the vicinity of peripheries of both surfaces of the supporting
pad 10.
[0035] And a first rotation zone 20 is installed at the periphery
of one side of the supporting pad 10. One surface of the first
rotation zone 20 is hinge-combined at one side of the supporting
pad 10, thereby the first rotation zone 20 is capable of rotating
up to approximate 180.degree. around the supporting pad 10. A
second rotation zone 30 is hinge-combined at an upper part of the
first rotation zone 20.
[0036] Two pairs of four link connection portions 31 are protruded
at a lower part of the second rotation zone 30. Each link
connection portion 31 is inserted and combined at an upper part of
the first rotation zone 20, thereby each link connection portion 31
is capable of rotating.
[0037] The second rotation zone 30 has a rectangular planar
structure having relatively a smaller size than the supporting pad
10. Ruggedness section 32 is formed on both surfaces of the second
rotation zone 30 and is protruded multitudinously in a row to the
direction of the length. This is for preventing shoes from sliding
when a user tries changing one surface of the floor cloth 90 to the
other surface and for holding the floor cloth 90 so that the floor
cloth 90 does not slide.
[0038] A rotation incision portion 33 is formed at an upper part of
the second rotation zone 30 and is incised to the direction of the
length with a rectangular structure. Here, protrusions 33A are
protruded oppositely on both sides of the rotation incision portion
33.
[0039] A roller 40 is hinge-combined at inside of the rotation
incision portion 33. The roller 40 comprises a pair of hinge
combination sections 41 formed at both sides like a wheel, and a
connection shaft 42 to connect two hinge combination sections 41
respectively. The connection shaft 42 has a smaller diameter than
that of the hinge combination sections 41.
[0040] Here, a hinge hole 41A is formed at each end of the hinge
combination sections 41 so that the roller 40 rotates smoothly with
the protrusions 33A of the rotation incision portion 33 as a center
axis, and has a relatively larger diameter than protrusions
33A.
[0041] As configured above, the second rotation zone 30 is capable
of rotating in an angular range of about 360.degree. with the
supporting pad 10 as a center axis by rotations of the first
rotation zone 20 and the roller 40. In accordance with this, the
second rotation zone 30 has a structure selectively attached on
both sides of the supporting pad 10. Accordingly, if the second
rotation zone 30 is attached on one surface of the supporting pad
10, the first rotation zone 20 is erected approximately
perpendicularly and the second rotation zone 30 is laid down
approximately horizontally.
[0042] In addition, a connection member 60 is collectively formed
at the connection shaft 42 of the roller 40 perpendicularly. The
connection member 60 has a structure of which a width is lessened
to the direction of the height. A lower part of a stick 70 is
hinge-combined, thereby the stick 70 is capable of rotating with
the roller 40 as an axis.
[0043] This stick 70 has a grip 71 formed of plastics on an upper
part, which a user is able to grasp and push the floor mop 100. And
a hole 71A is formed on an upper part of the grip 71 so that the
floor mop 100 is capable of being hung by a nail, and the like.
[0044] The present invention needs means for pressing and fixing
the floor cloth 90 between the supporting pad 10 and the second
rotation zone 30 in accordance with a selective attachment of the
second rotation zone 30. For this, a permanent magnet 80 and a
steel portion 81 are installed at the second rotation zone 30 and
the supporting pad 10, respectively. That is, the permanent magnet
80 is fixed on both surfaces of the second rotation zone 30, and
the steel portion 81 is fixed on the supporting pad 10 at a
position corresponding to the location of the permanent magnet 80.
However, positions of the permanent magnet 80 and the steel portion
81 are not limited like above, the positions may be exchanged each
other.
[0045] Accordingly, if selective one of both surfaces of the
supporting pad 10 is attached to one surface of the second rotation
zone 30, the floor cloth 90 is capable of being pressed and fixed
between the second rotation zone 30 and the supporting pad 10 by a
magnetic force of the permanent magnet 80 and the steel portion
81.
[0046] FIG. 5 is a using state view of a floor mop capable of using
both sides of FIG. 1. As shown in FIG. 5, a floor cloth 90 of a
floor mop 100 is installed on both surfaces of the supporting pad
10 and fixed by velcro tape 12. A stick 70 is mounted at one
surface of the floor cloth 90, thereby a user is able to push the
stick 70 and clean a selective position with another surface of the
floor cloth 90 of the floor mop 100 attached on a ground.
[0047] If a user wishes to use the other surface of the floor cloth
90 since one surface is made unclean, he lifts the stick 70 while
stepping on the supporting pad 10 with a larger force than the
magnetic force, thereby he is able to lift up the roller 40 and
rotate the supporting pad 10 to the other surface. Then, he steps
on the ruggedness section 32 of the second rotation zone 30 so that
the second rotation zone 30 is reliably attached on the other
surface of the floor cloth. In accordance with this, a magnetic
force between the permanent magnet 80 and the steel portion 81 is
applied, thereby the floor cloth is pressed and fixed. The floor
mop 100 is collectively moved by the magnetic force of the
permanent magnet 80.
[0048] FIG. 6 is a schematic view of a second embodiment of a floor
mop capable of using both sides according to the present invention,
and FIG. 7 is a side view of a floor mop capable of using both
sides of FIG. 6. FIG. 8 is a back plain view of a floor mop capable
of using both sides of FIG. 6. As shown in FIG. 6, FIG. 7, and FIG.
8, a floor mop capable of using both sides according to the present
invention has a rotation structure for selectively pressing and
fixing both sides of the floor cloth 90 to the supporting pad 10 at
which the floor cloth 90 is mounted. The rotation structure is
formed of a permanent magnet 80 to press and fix the floor cloth 90
by magnetic force.
[0049] Here, the rotation structure is formed of a rotation section
50, wherein the rotation section 50 has a connection structure
which comprises a first rotation zone 20 hinge-combined with the
supporting pad 10, a second rotation zone 30 hinge-combined with
the first rotation zone 20, and a roller 40 hinge-combined with the
second rotation zone 30, thereby the rotation structure is capable
of rotating smoothly.
[0050] The first rotation zone 20 is mounted at a curvature portion
of a central periphery of one side of the supporting pad 10
attached on the floor cloth 90 to the direction of the length. This
first rotation zone 20 is capable of rotating with the supporting
pad 10 as the axis since a lower part of the first rotation zone 20
is hinge-combined with the periphery of the supporting pad 10.
[0051] And a second rotation zone 30 is hinge-combined with an
upper part of the first rotation zone 20. An upper part of the
first rotation zone 20 and a lower part of the second rotation zone
30 are engaged by repetitive protrusions and corresponding
depressions.
[0052] Sockets 34 are formed opposite at both upper sides of the
second rotation zone 30 symmetrically, which have hemisphere
shapes. Socket protrusions 34A are oppositely protruded at the
center of inside surface.
[0053] A roller 40 is installed between the sockets 34. The roller
40 comprises a pair of hinge combination sections 41 formed on both
sides of the roller as a wheel shape, and a connection shaft 42
connecting the hinge combination sections 41 with a relatively
smaller diameter than the hinge combination sections 41.
[0054] Here, each hinge combination section 41 is inserted in each
socket 34 corresponding thereto. Each socket protrusion 34A is
hinge-combined by being inserted to a central groove of one surface
of each hinge combination section 41. Accordingly, the roller 40 is
capable of rotating with the sockets as an axis.
[0055] Accordingly, as described above, the roller 40 is capable of
rotating in an angular range of about 360.degree. with the
supporting pad 10 as the center axis, and has a structure
selectively attached on both sides of the supporting pad 10.
Accordingly, if the roller 40 is attached on one surface of the
supporting pad 10, the first rotation zone 20 is erected
approximately perpendicularly and the second rotation zone 30 is
laid down approximately horizontally.
[0056] In addition, a connection member 60 is formed at the
connection shaft 42 of the roller 40 with perpendicular to the axis
of the shaft. The connection member 60 has a structure of which a
width is lessened to the direction of the height. A lower part of a
stick 70 is hinge-combined with an upper part of the connection
member 60, thereby the stick 70 is capable of rotating with
perpendicular to the rotation direction of the rotation section
50.
[0057] The present invention needs means for pressing and locking
up the floor cloth 90 between the supporting pad 10 and the roller
40 in accordance with a selective attachment of the roller 40. For
this, a permanent magnet 80 and a steel portion 81 are installed at
the roller 40 and the supporting pad 10, respectively. That is, the
permanent magnet 80 is fixed on lower parts of both sides of the
roller 40, and the steel portion 81 is fixed on the supporting pad
10 at a position corresponding to the location of the permanent
magnet 80.
[0058] Accordingly, if selective one of both surfaces of the
supporting pad 10 is attached to one surface of the roller 40, the
floor cloth 90 is capable of being pressed and fixed between the
roller 40 and the supporting pad 10 by a magnetic force of the
permanent magnet 80 and the steel portion 81.
[0059] FIG. 9 is a sectional view of a roller and a supporting pad
of a floor mop capable of using both sides of FIG. 6. As shown in
FIG. 9, the roller 40 is formed as a shaft with wheels, and
comprises a hinge combination section 41 and a connection shaft 42.
Here, the hinge combination section 41 has a wheel shape inserted
into a socket 34 of the second combination zone 30, and the
connection shaft 42 has a shaft shape connecting each hinge
combination section 41.
[0060] Here, a protrusion 34A of the socket 34 is inserted at a
center of one surface of the hinge combination section 41, thereby
the roller 40 is capable of rotating. And, ball bearings are
mounted at periphery of the hinge combination section 41 to the
radial direction thereof so that a rotation structure of the roller
40 is strengthened.
[0061] The peripheries of the hinge combination section 41
corresponding to the positions of the ball bearings are hollowed
for ball bearings combination structure like above described.
Accordingly, side sections of the socket 34 are point-contacted
corresponding to the bearings, thereby a frictional coefficient
between the socket 34 and the hinge combination section 41 is
relatively lessened.
[0062] An incision portion 43 is formed to the axial direction on
the connection shaft 42. A permanent magnet 80 is inserted at the
incision portion 43 with being exposed externally. Steel portions
81 are fixed on both sides of the supporting pad 10 corresponding
to the position of the permanent magnet 80. Accordingly, the
permanent magnet 80 is attached to each steel portion 81 by a
magnetic force with a selective rotation.
[0063] If a user wishes to use the other surface of the floor cloth
90 since one surface is made unclean, he lifts the stick 70 while
stepping on the supporting pad 10 with a larger force than the
magnetic force, thereby he is able to lift up the roller 40 and
rotate the supporting pad 10 to the other surface so that the
roller 40 is attached on the other surface of the floor cloth 90.
Here, since a steel portion 81 is also formed on the other surface
correspondingly, the floor cloth 90 is capable of being pressed and
fixed.
[0064] If a user wishes to exchange the floor cloth 90 with a new
one, he lifts the roller 40 by lifting the stick 70, thereby the
rotation section 50 is detached from the supporting pad 10. After
exchanging the floor cloth 90, he recovers the rotation section 50
by moving the stick 50, thereby the exchanged floor cloth 90 is
attached to the roller 40. Accordingly, the floor cloth 90 is
pressed and fixed by a magnetic force between the permanent magnet
80 and the steel portion.
[0065] FIG. 10 is a sectional view of a roller and a supporting pad
of a floor mop capable of using both sides according to a third
embodiment of the present invention. As shown in FIG. 10, the
structure of the third embodiment is similar to that of the second
embodiment. A difference is that each incision portion 43 is
respectively formed at a lower part and an upper part of each hinge
combination section 41, and that a permanent magnet 80 is fixed at
each incision portion 43, and that totally four magnets 80 are
inserted and fixed. Here, each steel portion 81 is fixed to the
corresponding position attached to the roller 40 on both surfaces
of the supporting pad 10.
[0066] Accordingly, a floor cloth 90 is pressed and fixed between
the roller 40 and the supporting pad 10 by a magnetic force of the
permanent magnet 80 and the steel portion 81.
[0067] FIG. 11 is a using state view of a floor mop capable of
using both sides of FIG. 6 and FIG. 10. As shown in FIG. 11, a
floor cloth 90 is mounted at the floor mop 100 in accordance with
periphery of a supporting pad 10 and is fixed by a velcro tape 12.
Accordingly, one surface of the floor cloth 90 is pressed and fixed
by a magnetic force between the permanent magnet 80 installed at
the connection shaft 42 or the hinge combination section 41 of the
roller 40 and the steel portion 81 fixed on both surfaces of the
supporting pad 10 corresponding to a position of the permanent
magnet 80.
[0068] A stick 70 is positioned at one surface of the fixed floor
cloth 90. In accordance with that, a user is able to push the stick
70 to a selective direction after adhering the other surface of the
floor cloth 90 and uses the floor mop 100. If a user wishes to use
the other surface of the floor cloth 90 since one surface is made
unclean, he grasps the stick 70 while stepping on the supporting
pad 10 with a larger force than the magnetic force, thereby he is
able to lift up the roller 40 by separating a magnetic combination
between the roller 40 and the supporting pad 10. And he is able to
rotate the rotation section 50 to the other surface of the
supporting pad 10 and combine between the steel portion 81 of the
other surface and the permanent magnet 80 by a magnetic force,
thereby the other surface of the floor cloth 90 is pressed and
fixed. Accordingly, the stick 70 is positioned at the other surface
of the floor cloth 90, and a relatively clean surface is adhered on
the ground and used.
[0069] FIG. 12 is a schematic view of a fourth embodiment of a
floor mop capable of using both sides according to the present
invention. As shown in FIG. 12, a structure of the fourth
embodiment is similar to that of the second embodiment. But, a
roller 40 is formed of a cylindrical shape having a constant
diameter under the condition that the roller is not divided by a
hinge combination section 41 and a connection shaft 42, which is
different from other embodiments. This roller 40 has a diameter
that one surface of the roller 40 contacts on the bottom plate, is
hinge-combined at protrusions 33A formed at a rotation incision
33.
[0070] Here, a permanent magnet 80 is mounted on a lower part of
the roller 40 which is symmetric to the connection member 60 or on
both surfaces of the supporting pad 10 corresponding to said lower
part of the roller 40, and a steel portion 81 is fixed on a
position opposite to the permanent magnet 80. The permanent magnet
80 and the steel portion 81 like above organized press and fix the
floor cloth 90 installed between the roller 40 and the supporting
pad 10.
INDUSTRIAL APPLICABILITY
[0071] A floor mop capable of using both sides according to the
present invention is capable of using another permanent magnet
having a contrary polarity of the permanent magnet according to the
present invention instead of the steel portion, and of changing the
positions between the steel portion and the permanent magnet.
[0072] And the present invention is capable of using a press
button, clamp, and the like as means for fixing the floor cloth
mounted on the supporting pad, instead of the velcro tape.
[0073] The supporting pad and the floor cloth mounted thereon may
be changed to a suitable structure for cleaning if a cleaning area
is small, instead of the rectangular shape. For example, a
direction to push the floor mop may be set to the direction of the
length. The shapes of the supporting pad and the floor cloth may be
selected one of a perfect square, a circle, a pentagon, a hexagon,
etc.
[0074] In addition, the floor cloth is preferably formed of cottons
or micro-fibers.
[0075] And needle bearings, general journal bearings, etc may be
installed at the hinge combination section instead of ball
bearings. Protrusions may be formed on one surface corresponding to
the hinge combination section and grooves may be formed inside of
the socket, thereby the present invention is hinge-combined as
above, instead of forming protrusions at the socket.
[0076] In addition, the stick may be a multi-stage combination
structure so as to adjust the length.
[0077] As the present invention may be embodied in several forms
without departing from the spirit or essential characteristics
thereof, it should also be understood that the above-described
embodiments are not limited by any of the details of the foregoing
description, unless otherwise specified, but rather should be
construed broadly within its spirit and scope as defined in the
appended claims, and therefore all changes and modifications that
fall within the meets and bounds of the claims, or equivalence of
such meets and bounds are therefore intended to be embraced by the
appended claims.
