DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, embodiments of the cleaning jig according to the present invention will be described in detail with reference to the drawings. However, although the embodiments described below have various limitations that are technically preferable for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples. The following description will be given with the X-axis, Y-axis, and Z-axis, as well as the front-rear, left-right, and up-down directions defined as shown in FIG.

[0014] [Configuration of the embodiment] As shown in FIG. 1, the cleaning jig 100 of this embodiment includes a head portion 1 to which a cleaning sheet P is attached, a shaft portion 2 to which the head portion 1 is attached, a handle portion 3 by which a user holds the cleaning jig 100, and a joint portion 4 connecting the shaft portion 2 and the handle portion 3.

[0015] (cleaning sheets) The cleaning sheet P is a sheet that is replaceably attached to the head part 1 of the cleaning jig 100, and covers the upper and lower surfaces of the head part 1.

[0016] The cleaning sheet P has a generally rectangular shape in plan view, with its long sides extending in the Y-axis direction. Specifically, for example, the size in the X-axis direction is 140 mm to 240 mm, preferably 160 mm to 210 mm, and the size in the Y-axis direction is 280 mm to 340 mm, preferably 300 mm to 320 mm.

[0017] The cleaning sheet P may be made of nonwoven fabric or paper, and may be dry or wet. It may also be embossed for dust collection and decorative purposes. To facilitate attachment to the head unit 1, the cleaning sheet P may be folded at the location where it comes into contact with the head component 10 (described later).

[0018] (head section) 2A shows the head portion 1. The head portion 1 is, for example, a member having a substantially rectangular shape in a plan view, and is formed from, for example, ABS (acrylonitrile butadiene styrene copolymer) resin, EVA (ethylene vinyl acetate copolymer) resin, nylon, polyacetal, or the like. The head portion 1 includes two head components 10, 10.

[0019] {Head components} The head component 10 is a plate-like member that is elongated in the X-axis direction and has a generally rectangular shape in plan view. Specifically, for example, the size in the X-axis direction is 150 mm to 250 mm, preferably 170 mm to 220 mm, and the size in the Y-axis direction is 50 mm to 75 mm, preferably 55 mm to 67.5 mm. That is, the short sides of the head unit 1 are set to be half or less the length of the long sides of the cleaning sheet P. The long sides of the head constituent member 10 are set to be longer than the short sides of the cleaning sheet P. The head component 10 has a sheet fixing portion 12 on a first side surface portion 11. Also, a rotation shaft holding portion 14 is provided on a second side surface portion 13 opposite the first side surface portion 11.

[0020] [Seat fixing part] FIG. 2B is an enlarged view of the first side surface portion 11. As shown in FIG. The sheet fixing part 12 has an insertion part 121, which is a hole that is elongated in the X-axis direction and is provided in, for example, approximately the center in the Z-axis direction of the first side part 11, and a claw-shaped locking member 122 provided at the opening of the insertion part 121. Then, by inserting an end of the cleaning sheet P into the insertion part 121 and locking it with the locking member 122, the cleaning sheet P can be fixed to the head part 1. The shape of the locking member 122 is not limited to the claw-like shape shown in Fig. 2B, but may be any known shape, such as a wave-shaped locking member 122 shown in Fig. 2C.

[0021] The sheet fixing part 12 may be provided on the first side surface part 11 of the head component 10 and may be configured to be able to fix the cleaning sheet P. In other words, in the above example, the insertion part 121 is a single long hole into which one end of the cleaning sheet P is entirely inserted, but this is not limiting. For example, the insertion part 121 may be multiple (e.g., two) short holes into which one end of the cleaning sheet P is partially inserted.

[0022] Furthermore, the locking member 122 is not limited to being provided in the insertion portion 121. For example, instead of providing the insertion portion 121, a clip that is rotatable in the Y-axis direction may be provided as the locking member 122, and one end of the cleaning sheet P may be clamped between the first side surface portion 11. Furthermore, the sheet fixing portion 12 may be configured to fix the cleaning sheet P to the head unit 1 using any other conventionally known structure. However, because the head component 10 can be easily manufactured and the first side portions 11 are less likely to get in the way when facing each other, it is preferable that the sheet fixing portion 12 be configured to include an insertion portion 121 and a locking member 122, as shown in Figure 2B.

[0023] [Rotation shaft holding part] 2A, the pivot shaft holding portion 14 is a holding portion that holds a pivot shaft 21 (described later) of the shaft portion 2, and is provided on the second side surface portion 13 of the head constituent member 10. The pivot shaft holding portion 14 is made of, for example, ABS resin, EVA resin, nylon, polyacetal, or the like.

[0024] (shaft) 3 shows the shaft 2 and handle 3 connected via the joint 4. The shaft 2 is made of, for example, steel or aluminum, and is formed into a generally U-shape with one side of a generally rectangular frame cut out to open it when viewed from above. The lengths of the shaft 2 in the X-axis and Y-axis directions are longer than the lengths of the head 1 in the X-axis and Y-axis directions. The shaft portion 2 includes rotation shafts 21, 21 that are provided so as to face each other in the X-axis direction, and a connection portion 22 that connects one end of the rotation shafts 21, 21 to each other.

[0025] {Pivot shaft, connection part} 1, the rotation shafts 21, 21 are formed so that their length in the X-axis direction is slightly longer than the length of the head unit 1 in the X-axis direction, and are inserted into the rotation shaft holders 14, 14, respectively. Furthermore, the connection part 22 is formed so that it is slightly longer than the length of the head unit 1 in the Y-axis direction, and is positioned so as to substantially abut against a third side surface portion, which is the side surface portion of the head unit 1 in the Y-axis direction.

[0026] In this way, the shaft portion 2 is provided so that the rotating shafts 21, 21 and the connecting portion 22 abut on three sides of the head portion 1, thereby maintaining the shape of the head portion 1 in a substantially rectangular shape during cleaning. Furthermore, the rotating shaft 21 is inserted through the rotating shaft holding portions 14, 14, so that the head component 10 can rotate around the rotating shaft 21 as an axis. Although FIG. 3 shows an example in which the rotary shaft 21 and the connecting portion 22 are integrally formed, the present invention is not limited to this, and the two may be formed from separate members.

[0027] (handle) The handle 3 is a rod-shaped member used when using the cleaning jig 100, and cleaning is performed by the user gripping it and sliding the head 1 in any direction on the surface to be cleaned. The handle 3 is formed from, for example, ABS resin, EVA resin, metal (aluminum, steel, stainless steel), polycarbonate, PE (polyethylene), PP (polypropylene), or the like. The handle 3 is rotatably connected to the shaft 2 via the joint 4, and the front-to-back, left-to-right, and up-to-down directions will be defined in the description when the handle 3 is placed vertically on the shaft 2 as shown in Figures 1 and 3. The handle 3 includes a handle body 31 and a grip 32 .

[0028] {Handle body} 1 and 3, the handle body 31 is a rod-shaped member. The lower end of the handle body 31 is connected to the connecting part 22 at approximately the center in the Y-axis direction via the joint part 4, and the upper end The end is connected to the grip portion 32. The handle body 31 is formed to have a length in the Z-axis direction of 500 mm to 1000 mm, more preferably 600 mm to 900 mm. In addition, the handle body 31 is formed so that the thickness in the front-to-back direction near the bottom end is thinner than the thickness in the left-to-right direction, making it easier to tilt the handle 3 down to a low position.

[0029] It should be noted that the handle body 31 is not limited to being a single long member, but may be configured to be a long member by connecting a plurality of divided short members. Furthermore, although the effect of making it easier to tilt the handle 3 to a low position is reduced, the lower end portion of the handle body 31 may be formed to have the same thickness in the front-to-rear direction and the left-to-right direction. Alternatively, in order to prioritize the strength of the second protrusion 421 described below, the thickness in the front-to-rear direction may be greater than the thickness in the left-to-right direction.

[0030] {gripping part} The grip portion 32 is the portion of the handle portion 3 that is gripped by the user when using the cleaning tool 100. The grip portion 32 is connected to the handle body 31 at its lower end. The gripping portion 32 is formed to have a length in the Z-axis direction of 100 mm to 400 mm, more preferably 250 mm to 350 mm, and is formed to have a generally circular shape with a diameter of 15 mm to 45 mm, more preferably 20 mm to 40 mm, at its thickest point in plan view. The grip portion 32 may be formed as a separate member from the handle body 31 as in this embodiment, or may be formed integrally with the handle body 31.

[0031] (Joint part) As shown in Figures 1 and 3, the joint portion 4 is formed from a first yoke portion 41 provided at approximately the center of the connection portion 22 in the Y-axis direction, a second yoke portion 42 provided at the lower end of the handle portion 3, and a connecting portion 43 connecting the first yoke portion 41 and the second yoke portion 42. In this embodiment, the portion formed with two symmetrical projections and used for connection to other members is called a "yoke portion." The joint portion 4 is made of, for example, ABS resin, EVA resin, nylon, polyacetal, or the like.

[0032] {First yoke section} 4 shows the first yoke portion 41. The pair of first yoke portions 41, 41 is formed by a first protrusion 411 that is integrally formed at the center of the side surface of the connecting portion 22 of the shaft portion 2.

[0033] [First protrusion] The first protrusions 411 are formed so that, when viewed from the X-axis direction, the height gradually increases toward a first opposing surface 4111 where the first protrusions 411 face each other. The first protrusions 411 are arranged so as to be aligned along the Y-axis.

[0034] First protrusions 411 are formed to be 5 mm to 20 mm, preferably 8 mm to 15 mm, in the X-axis direction and 10 mm to 50 mm, preferably 15 mm to 30 mm, in the Y-axis direction. Furthermore, near first opposing surface portions 4111, which are the highest, they are formed to be 5 mm to 15 mm, preferably 8 mm to 12 mm, in the Z-axis direction. Furthermore, first protrusions 411 are arranged so that the first opposing surface portions 4111 are spaced apart by 10 mm to 25 mm, preferably 15 mm to 20 mm.

[0035] <First facing surface> The first opposing surface portions 4111 are surfaces where the first protrusions 411 face each other. The first opposing surface portions 4111 are formed in a substantially rectangular shape that stands upright substantially perpendicularly from the connection portion 22, and the first opposing surface portions 4111 are formed so as to be parallel to each other. As shown in FIG. 4, the first opposing surface portion 4111 has a hole portion 4113 formed therein.

[0036] <Hole> The hole portion 4113 is a cylindrical hole formed in the first opposing surface portion 4111. The hole portion 4113 is used for connection with the first rotation axis portion 431 of the connecting portion 43, as will be described later.

[0037] <Side part> The side surface portion 4112 is a surface of the first protrusion 411 that faces the X-axis direction parallel to the YZ plane and is formed continuously from both the left and right sides of the first opposing surface portion 4111. The side surface portion 4112 is formed to stand approximately perpendicularly from the connection portion 22.

[0038] {Second yoke} 5 shows second yoke portion 42. Second yoke portion 42 is formed at the lower end of handle body 31 of handle 3, and is composed of two symmetrically shaped second protrusions 421, 421 extending in the axial direction, and a second shaft member 422 spanning between second opposing surface portions 4211 of second protrusions 421.

[0039] [Second protrusion] The second protrusion portion 421 is formed integrally with the handle body 31 at both ends in the X-axis direction of the lower end of the handle body 31 in the state shown in Figure 1, so that the second opposing surface portions 4211 face each other in parallel and have a predetermined distance between them.

[0040] Second protrusion 421 has a thickness in the X-axis direction of 2 mm to 6 mm, preferably 3 mm to 5 mm, and has a width in the Y-axis direction that is approximately the same as that of handle body 31. If the thickness in the X-axis direction is too thin, it will not be strong enough to withstand pressure during cleaning, which may lead to breakage, whereas if it is too thick, when the handle is tilted in the X-axis direction, handle 3 will interfere with connecting part 22, making it difficult to tilt it to approximately parallel. The second opposing surface portions 4211 are formed so as to have a gap of 2 mm to 10 mm, preferably 3 mm to 7 mm between them.

[0041] [Second shaft member] The second shaft member 422 is formed integrally with the second protrusion portion 421 so as to bridge the second opposing surface portions 4211 along the X axis at the center in the Y axis direction.

[0042] {connection part} Fig. 6 shows the connecting portion 43. As shown in Figs. 1, 3, and 6, the connecting portion 43 is disposed between the first yoke portion 41 and the second yoke portion 42 so as to have a generally triangular shape when viewed from the front. The connecting portion 43 also includes a first rotation axis portion 431 and a second rotation axis portion 432 whose central axes intersect at right angles without intersecting each other in an overpass.

[0043] [First rotation axis center] 6, the first rotation axis portion 431 is a portion formed at the lower end of the connecting portion 43 and used for connection with the first yoke portion 41. The first rotation axis portion 431 has cylindrical protrusions 4311 at both ends in the Y-axis direction.

[0044] The width of the first rotation axis portion 431 in the Y-axis direction excluding the protrusions 4311 is substantially the same as the distance between the first opposing surface portions 4111 of the first protrusions 411. 13. Therefore, by fitting the protrusion 4311 into the hole 4113, the connecting portion 43 can be attached to the first yoke portion 41 so as to be rotatable around the Y axis. The central axis of the first rotation axis portion 431 along the Y axis is defined as a first axis a.

[0045] [Second rotation axis center] The second rotation axis portion 432 is a portion formed at the upper end of the connecting portion 43 and used for connection to the second yoke portion 42. The second rotation axis portion 432 has a portion of its upper end cut out, and has a second mounting hole 4321 that is substantially cylindrical and penetrates in the front-to-rear direction. The second mounting hole 4321 has a cylindrical space formed therein whose diameter is substantially the same as the diameter of the second shaft member 422. The second mounting hole 4321 is also formed so that its length in the X-axis direction is substantially the same as the length of the second shaft member 422. By fitting the second shaft member 422 into the second mounting hole 4321, the connecting portion 43 can be fixed to the second yoke portion 42 so as to be rotatable about the X-axis. The central axis of the second rotation axis portion 432 along the X axis is referred to as a second axis b.

[0046] 1, the handle 3 connected to the connection part 22 via the joint part 4 having such a connecting part 43 can rotate in a direction substantially parallel to the connection part 22 (left-right direction) and around an axis substantially parallel to the rotation axis 21 (front-rear direction). Therefore, by turning the cleaning jig 100 upside down and rotating the handle 3 in the front-rear direction, not only the lower surface but also the upper surface of the head part 1 can be cleaned, thereby reducing the unused area of ​​the cleaning sheet P.

[0047] The configuration that allows both sides of the head unit 1 to be used for cleaning is not limited to a configuration in which the handle unit 3 is rotatable in the front-to-rear direction. For example, the connecting portion 22 may be made separable from the rotating shafts 21, 21, and the head unit 1 separated from the connecting portion 22 may be turned over and then reconnected to the rotating shafts 21, 21 and the connecting portion 22, so that the top surface of the head unit 1 can be used as the cleaning surface. In the following description, it is assumed that the handle 3 can be rotated back and forth to make the top surface of the head 1 a cleaning surface.

[0048] [How to attach the cleaning sheet and how to use the cleaning tool] 7A to 7C and 8A to 8C, a method for attaching the cleaning sheet P to the head part 1 and a method for using the cleaning jig 100 will be described. Note that the connection part 22 and the handle part 3 are omitted from Figures 8A to 8C.

[0049] When using the cleaning jig 100 according to this embodiment, first, as shown in FIGS. 7A and 8A, the rotation shafts 21, 21 of the shaft portion 2 are inserted into the rotation shaft holding portions 14, 14 of the head constituent member 10, and the ends of the short sides of the cleaning sheet P are fixed to the sheet fixing portions 12, 12 of the head constituent members 10, 10, respectively.

[0050] Depending on the configuration of the cleaning jig 100, the step of attaching the head component 10 to the shaft portion 2 may be omitted.

[0051] After the cleaning sheet P is fixed to the head components 10, 10, the head components 10, 10 are rotated in opposite directions around the rotation shafts 21, 21 as the center, as shown in FIGS. 7B and 8B.

[0052] At this time, since the cleaning sheet P is fixed to the sheet fixing part 12, the cleaning sheet P is attached so as to wrap around the head components 10, 10, as shown in Fig. 8B. As a result, the upper and lower surfaces of the head part 1 are covered with the first surface of the cleaning sheet P facing outwards.

[0053] After the head unit 1 is covered with the cleaning sheet P, cleaning is performed using the cleaning jig 100. The head unit 1 is made up of separate head components 10, 10, but as mentioned above, the cleaning sheet P is attached so that it wraps around the head components 10, 10. Therefore, the cleaning sheet P unites the head components 10, 10 together, providing the head unit 1 with sufficient strength.

[0054] After the cleaning sheet P in contact with the underside of the head part 1 has sufficiently collected dust, the head part 1 is turned over and the handle part 3 is rotated forward around the joint part 4. Then, the face of the head part 1 that was previously the upper face becomes the lower face, i.e., the cleaning face, and cleaning is carried out again.

[0055] After the first surface of the cleaning sheet P covering the upper and lower surfaces of the head unit 1 has sufficiently collected dust, the head constituent members 10, 10 are rotated two times in the same direction as the rotation directions shown in FIGS. 7B and 8B, as shown in FIGS. 7C and 8C. This covers the upper and lower surfaces of the head unit 1 so that the second surface of the cleaning sheet P faces outward, and dust is collected by the second surface of the cleaning sheet P covering the upper and lower surfaces of the head unit 1, as described above. Then, once dust collection is complete, the cleaning sheet P is removed from the sheet fixing parts 12, 12 and discarded.

[0056] [Effect description] As described above, the cleaning jig 100 of this embodiment comprises a head portion 1 to which a cleaning sheet P is attached, a shaft portion 2 having a pivot shaft 21 for rotating the head portion 1, and a handle portion 3 connected to the shaft portion 2 and for a user to grip; the head portion 1 comprises two head components 10, 10 that are approximately rectangular in plan view; each of the two head components 10, 10 has a sheet fixing portion 12, 12 to which the cleaning sheet P can be fixed, and a pivot shaft holding portion 14, 14 through which one pivot shaft 21 can be inserted; the sheet fixing portion 12 is provided on a first side portion 11 of the head component 10; the pivot shaft holding portion 14 is provided on a second side portion 13 of the head component 10 opposite the first side portion 11; and the shaft portion 2 has a connection portion 22 that connects one end of the two pivot shafts 21, 21 together.

[0057] In this configuration, when the cleaning sheet P is fixed to the sheet fixing parts 12, 12 and then attached to the head unit 1 by rotating the first head component 10 in a first direction and the second head component 10 in a second direction, the first surface of the cleaning sheet P covers the upper and lower surfaces of the head unit 1. On the other hand, when the cleaning sheet P is attached to the head unit 1 by rotating the first head component 10 in the second direction and the second head component 10 in the first direction, the second surface of the cleaning sheet P covers the upper and lower surfaces of the head unit 1. Therefore, both sides (first and second sides) of the cleaning sheet P can be used for cleaning with less effort than the series of steps of rotating the two head components 10, 10, removing the cleaning sheet P from the head part 1, turning it over and reattaching it.

[0058] Handle 3 is connected to connecting portion 22 and is rotatable about an axis extending in a direction substantially parallel to connecting portion 22 (left-right direction) or a direction substantially parallel to rotating shaft 21 (front-rear direction). According to this configuration, not only the lower surface but also the upper surface of the head unit 1 can be used as a cleaning surface for cleaning, thereby reducing unused areas of the cleaning sheet P.

[0059] [Variations] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention.

[0060] For example, in the cleaning jig 100 shown in Fig. 1, the head component 10 is detachable from the pivot shaft 21. This has the advantage that the head component 10 is replaceable and that the cleaning jig 100 can be easily assembled and separated for disposal. However, there is a risk that the head component 10 may separate from the pivot shaft 21 when, for example, the cleaning jig 100 is slid backward during cleaning. This can be prevented by increasing the frictional resistance between the pivot shaft 21 and the pivot shaft holder 14, but in that case, it may become difficult to rotate the head component 10.

[0061] Therefore, a retaining portion 211 may be provided at the tip of the rotary shaft 21 to prevent the head component 10 from being separated from the rotary shaft 21. 9A, the tip of the rotating shaft 21 may be shaped like a pipe, and a cover longer than the width of the rotating shaft holder 14 may be attached to the rotating shaft 21 as the retaining portion 211. In this case, it is possible to obtain the advantage that the head component 10 described above is detachable from the rotating shaft 21. Furthermore, as shown in FIG. 9B, the tip of the rotating shaft 21 may be bent into a substantially L-shape, and the bent portion may be used as the retaining portion 211.

[0062] Furthermore, in FIG. 1, the shaft 2 is formed into a substantially U-shape, and the handle 3 is attached to one connecting portion 22 at substantially the center in the Y-axis direction, but this is not limiting. As described above, when cleaning using cleaning jig 100, the user grips handle 3 attached to connection 22 at the end in the X-axis direction. Therefore, depending on the shapes of head component 10 and head 1, sufficient force may be applied to one end of head 1 on the connection 22 side, but insufficient force may be applied to the other end opposite connection 22, which may result in insufficient dust collection.

[0063] Therefore, for example, as shown in Figure 10, the two ends of the rotating shaft 21 may be connected to each other by two connecting parts 22, 22 so that the shaft part 2 has an approximately rectangular shape when viewed in plan, and the handle part 3 may be connected to a second connecting part 23 that connects both connecting parts 22, 22. With this configuration, a force is applied to both ends of the head portion 1 (that is, the two connection portions 22, 22) via the second connection portion 23, so that dust can be sufficiently collected.

[0064] 10 illustrates an example in which the second connecting portion 23 is substantially inverted U-shaped, but is not limited to this. The shape of the second connecting portion 23 may be any shape that does not interfere with the rotation of the head constituent members 10, 10.

[0065] Furthermore, although each figure illustrates a configuration in which the handle portion 3 is connected to the shaft portion 2 via the joint portion 4, this is not limited to this, and the shaft portion 2 and the handle portion 3 may be formed as a single unit.

[0066] Furthermore, the present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the invention described in the claims and their equivalents. [Explanation of symbols]
