[0010] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.
[0011] <1. Configuration of cleaning tool with attachment> Fig. 1 is an external view of a cleaning tool with an attachment 1 according to an embodiment of the present invention. As shown in Fig. 1, the cleaning tool with an attachment 1 according to an embodiment of the present invention comprises a cleaning tool 10 and an attachment 20. The cleaning tool 10 comprises a handle portion 11, a cleaning head 12 and a connecting portion 14. The handle portion 11 comprises a plurality of tubular members 13 and a grip portion 16.
[0012] (Cylindrical member) The multiple tubular members 13 are arranged in one direction, and two adjacent tubular members 13 are detachably connected by a joint 13a. By providing the tubular members 13 between the cleaning head 20 and the grip part 16, a gap according to the length of the multiple tubular members 13 is generated between the cleaning head 20 and the grip part 16. This makes it possible for a user to clean a floor surface with the cleaning head 20 while holding the grip part 16 in an upright position.
[0013] The material of the tubular member 13 is not particularly limited and may be aluminum alloy, stainless steel, wood, synthetic resin such as PP (polypropylene) resin, ABS (acrylonitrile butadiene styrene), etc. Also, while Fig. 1 shows the tubular member 13 having a cylindrical shape, tubular members of other shapes may be used. For example, a tubular member having a rectangular tube shape may be used. Also, Fig. 1 shows an example in which multiple tubular members 13 are connected, but instead of the multiple tubular members 13, a single tubular member or an expandable member may be used.
[0014] (gripping part) The grip portion 16 is a portion that is held by the user's hand. In this embodiment, the grip portion 16 is connected to the cleaning head 20 via a plurality of tubular members 13. In detail, one end of the connected plurality of tubular members 13 is connected to the cleaning head 20 via the connecting portion 14, and the other end of the plurality of tubular members 13 is connected to the grip portion 16. When the cleaning tool 1 with the attachment is transported and sold, each member including the cleaning head 20, the plurality of tubular members 13, the grip portion 16, and the attachment 20 is separated. A user who purchases the cleaning tool 10 assembles the plurality of tubular members 13, attaches the attachment 20 to the tubular members 13, and connects the cleaning head 20 and the grip portion 16 via the plurality of tubular members 13, so that the cleaning tool 1 with the attachment is ready for use. Alternatively, the attachment 20 may be sold separately from the cleaning tool 10.
[0015] Handle 11 is a portion that can be gripped by a user when using cleaning tool 10, or a rod-shaped portion that is connected to cleaning head 12. In this specification, the portion that is primarily expected to be gripped by a user is particularly described as grip 16, but since a user can also grip tubular member 13, both grip 16 and tubular member 13 qualify as handle 11.
[0016] (Cleaning head) The cleaning head 12 is an example of a cleaning unit for cleaning a cleaning target such as a floor surface or a wall surface. When a user holds the grip part 16 and moves the cleaning tool with attachment 1, the cleaning head 12 moves while applying a surface pressure to the cleaning target such as a floor surface. This allows the cleaning target to be wiped clean.
[0017] Such a cleaning head 12 is formed from a known elastic body or resin film, such as a film using a thermoplastic resin such as polypropylene (PP) or polyethylene, a styrene-based or olefin-based thermoplastic elastomer, a thermosetting elastomer, etc. The cleaning head 12 has a generally flat plate shape with long sides of about 200 to 300 mm and short sides of about 50 to 150 mm, for example.
[0018] (Connection part) The connecting part 14 connects the handle 11 and the cleaning head 12 so that the handle 11 can rotate relative to the cleaning head 12. In other words, the connecting part 14 connects the handle 11 and the cleaning head 12 so that the position of the handle 11 relative to the cleaning head 12 can be any position.
[0019] (Wearing equipment) The attachment 20 is detachably attached to the handle 11 (particularly, the tubular member 13). The attachment 20 has a shape that surrounds the tubular member 13, and slides on the tubular member 13 along the axial direction of the tubular member 13. When the attachment 20 is in a position overlapping the tubular member 13 and the connecting portion 14, the rotation of the handle 11 relative to the cleaning head 12 is restricted. Therefore, when a user wishes to restrict the rotation of the handle 11 relative to the cleaning head 12, the user can move the attachment 20 to a position overlapping the tubular member 13 and the connecting portion 14. Below, the configurations of the above-mentioned cleaning head 12, the connecting portion 14, and the tubular member 13 will be described in more detail, and then the detailed configuration of the attachment 20 will be described.
[0020] <2. Cleaning head configuration> Fig. 2 is an explanatory diagram showing the configuration of the cleaning head 12. As shown in Fig. 2, the cleaning head 12 has a lower surface 121 and an upper surface 122. The lower surface 121 is a surface facing a cleaning target such as a floor surface or a wall surface, and the upper surface 122 is a surface opposite to the lower surface 121. The lower surface 121 may be made of a deformable elastic part, and the upper surface 122 may be made of plastic. Two raised portions 123 are formed on the upper surface 122. Each raised portion 123 has holes 124 formed opposite to each other.
[0021] A cleaning sheet (not shown) is removably attached to the cleaning head 12. For example, the cleaning sheet covers the underside 121 of the cleaning head 12 and is folded back along the long side of the cleaning head 12. The portion of the sheet folded back toward the upper surface 122 of the cleaning head 12 is then pushed into sheet holders 12a provided at the four corners of the upper surface of the cleaning head 12, thereby attaching the cleaning sheet to the cleaning head 12. As the cleaning sheet, a known sheet such as an olefin-based ultrafine fiber nonwoven fabric can be used. The state of the cleaning sheet can be a dry state or a wet state in which it is impregnated with a detergent or the like.
[0022] <3. Structure of the connecting part> 3 is an explanatory diagram showing the configuration of the connecting part 14. As shown in FIG. 3, the connecting part 14 has a head connecting part 141, a handle connecting part 142, and a fastener 143.
[0023] The head connector 141 has two projections 141a projecting in opposite directions. The projections 141a fit into holes 124 formed in the raised portion 123 of the cleaning head 12, thereby connecting the connector 14 and the cleaning head 12.
[0024] The handle connecting part 142 is a part that is connected to the handle 11. The end face of the handle connecting part 142 opposite to the head connecting part 141 has a curved shape. The fastener 143 has a shaft and large diameter parts located at both ends of the shaft. The axial direction of the shaft of the fastener 143 is perpendicular to the direction in which the two protrusions 141a are separated. The shaft of the fastener 143 passes through a hole formed in the handle connecting part 142. The outer diameter of the large diameter part of the fastener 143 is larger than the inner diameter of the hole formed in the handle connecting part 142, so that the fastener 143 does not fall off the handle connecting part 142.
[0025] <4. Configuration of tubular member> Fig. 4 is an explanatory diagram showing the configuration of the tubular member 13. Fig. 4 shows the configuration of the tubular member 13 that is located closest to the cleaning head 12 among the multiple tubular members 13. The tubular member 13 has a pair of opposing walls 132 at the end on the cleaning head 12 side. A hole 133 is formed in each wall 132. A groove 134 is formed between the pair of walls 132. A bottom 135 is the bottom of the groove 134 and is an example of a portion of the tubular member 13 that faces the cleaning head 12 side.
[0026] The handle connecting portion 142 of the connecting portion 14 enters the groove 134, the shaft portion of the fastener 143 passes through the holes 133 in each wall portion 132, and the large diameter portion of the fastener 143 presses against the outside of the hole 133, thereby connecting the tubular member 13 and the connecting portion 14.
[0027] Now, with reference to FIG. 5, the rotation of the tubular member 13 relative to the cleaning head 12 will be described.
[0028] 5 is an explanatory diagram regarding the rotation of the tubular member 13 relative to the cleaning head 12. The tubular member 13 is rotatable about a rotation axis L1 and a rotation axis L2 shown in FIG. 5 relative to the cleaning head 12. The rotation axis L1 is a rotation axis formed by fitting the protrusion 141a of the connecting part 14 into the hole 124 formed in the raised part 123 of the cleaning head 12. The rotation axis L2 is a rotation axis formed by connecting the handle connecting part 142 of the connecting part 14 to the wall part 132 via a fastener 143. A gap H is formed between the handle connecting part 142 and the bottom part 135 of the tubular member 13 (see FIG. 4) by the end face of the handle connecting part 142 on the bottom part 135 side having a curved shape.
[0029] In addition, in Fig. 5, the direction in which the holes 124 formed in each raised portion 123 of the cleaning head 12 are separated (i.e., the direction along the rotation axis L1) is shown as the X-axis direction, and the X-axis direction may be referred to as the width direction. In addition, in Fig. 5, the direction in which the two walls 132 are separated (i.e., the direction along the rotation axis L2) is shown as the Y-axis direction, and the Y-axis direction may be referred to as the front-rear direction. In addition, in Fig. 5, the axial direction of the handle 11 is shown as the Z-axis direction, and the direction toward the grip portion 16 in the Z-axis direction is an example of a second direction and is referred to as the grip direction (Z(G)), and the direction toward the cleaning head 12 in the Z-axis direction is an example of a first direction and is referred to as the head direction (Z(H)).
[0030] In the state shown in FIG. 5, the attachment 20 is in a position away from the connecting portion 14. As shown in FIG. 6, the user can move the attachment 20 to a position where the attachment 20 overlaps both the handle portion 11 and the connecting portion 14. As shown in FIG. 6, even when the attachment 20 is in a position where the attachment 20 overlaps both the handle portion 11 and the connecting portion 14, the handle portion 11 can rotate around the rotation axis L1. On the other hand, in the state shown in FIG. 6, the orientation of the handle portion 11 relative to the connecting portion 14 is fixed by the attachment 20, so that the rotation of the handle portion 11 relative to the cleaning head 12 around the rotation axis L2 is restricted. The user can release the restriction on the rotation around the rotation axis L2 by moving the attachment 20 in the grip direction (Z(G)). The configuration of the attachment 20 that realizes such a restriction on the rotation will be described in detail below.
[0031] <5. Composition of the attachment> Fig. 7 is an explanatory diagram showing the configuration of a mounting device 20 according to one embodiment of the present invention. As shown in Fig. 7, the mounting device 20 according to one embodiment of the present invention is made up of a locking member 21, which is an example of a first member, and a sliding member 22, which is an example of a second member that is slidable along the axial direction of the handle portion 11 relative to the locking member 21. The configuration of the locking member 21 will be described with reference to Figs. 7 to 9 and 12, and the configuration of the sliding member 22 will be described with reference to Figs. 7 and 10 to 12.
[0032] (locking member) Fig. 8 is a perspective view of the locking member 21. Fig. 12 is a cross-sectional view of the wearing fixture 20. As shown in Figs. 7, 8 and 12, the locking member 21 has a base portion 211, a claw portion 214 and an engagement portion 215.
[0033] The base 211 has a shape surrounding the handle 11. The base 211 may have a shape surrounding the periphery of the handle 11 over a 360-degree range as shown in FIG. 8, or may have a shape surrounding the periphery of the handle 11 over a range less than 360 degrees by forming a slit or the like. The base 211 has a through hole 213 into which the handle 11 is inserted. The shape of the through hole 213 as viewed along the axial direction (Z) of the handle 11 may be a non-circular shape. For example, when the handle 11 is designed to expand in the width direction at the end of the handle 11 toward the head (Z(H)), the length of the through hole 213 in the width direction (length d1 shown in FIG. 7) may be greater than the length of the through hole 213 in the front-rear direction.
[0034] The base 211 has a shape that tapers toward the head direction (Z(H)). More specifically, the thickness of the base 211 in the front-rear direction decreases toward the head direction (Z(H)).
[0035] The claw portion 214 has a region that is convex toward the handle portion 11 on the inner periphery side of the base portion 211. The claw portion 214 is connected to the base portion 211 at the end portion on the head direction (Z(H)) side of the base portion 211, as shown in Fig. 12. A space S is formed between the claw portion 214 and the base portion 211.
[0036] The engaging portion 215 extends from the base portion 211 in the grip direction (Z(G)). A protrusion 216 is formed at the tip of the engaging portion 215, protruding outward or inward from the handle portion 11 in the front-rear direction (Y). In the example shown in Fig. 8, an elliptical cylindrical protrusion 216 is formed at the tip of the engaging portion 215, protruding outward from the handle portion 11 in the front-rear direction (Y).
[0037] In this regard, as shown in the lower part of Fig. 9, a modified protrusion 218 may be formed at the tip of the engagement portion 215. The protrusion 218 has a tapered shape that protrudes less toward the grip direction (Z(G)). This tapered shape can improve the ease of assembly of the locking member 21 and the sliding member 22.
[0038] The above has described the configuration of the lock member 21. Next, the configuration of the slide member 22 will be described.
[0039] (Slide member) Fig. 10 is a perspective view of slide member 22. Fig. 11 is a perspective view of slide member 22 in a state assembled with lock member 21. As shown in Fig. 7 and Figs. 10 to 12, slide member 22 has two main surfaces 221 facing each other, two side surfaces 222 facing each other, a through hole 223, and two slide plates 225 facing each other.
[0040] The two main surfaces 221 are spaced apart in the front-rear direction (Y). The two side surfaces 222 are spaced apart in the width direction (X). The length of the main surfaces 221 in the width direction (X) is longer than the length of the side surfaces 222 in the front-rear direction (Y). That is, the longitudinal direction of the slide member 22 when viewed along the axial direction (Z) of the handle 11 is the width direction (X). The handle 11 is inserted into the through hole 223. The inner diameter of the through hole 223 is substantially the same as the outer diameter of the handle 11, and a curved surface R may be formed along the circumferential direction at the edge of the through hole 223 on the grip direction (Z(G)) side.
[0041] The main surface 221 has a finger hook 226. The finger hook 226 is formed along the width direction (X) and protrudes outward in the front-rear direction.
[0042] In addition, an opening 227 connected to the through hole 223 is formed in the main surface 221. An opening edge portion 228, which is the edge of the opening 227, has a U-shape. A protrusion 228a is formed in the opening edge portion 228 at portions facing each other along the Z-axis direction. An end portion of the opening edge portion 228 on the head direction (Z(H)) side has a semi-elliptical shape. Therefore, when the locking member 21 and the sliding member 22 are assembled, as shown in FIG. 11, the convex portion 216 of the engagement portion 215 of the locking member 21 comes into surface contact with the end portion of the opening edge portion 228 on the head direction (Z(H)) side. Note that there is a step between the top surface of the convex portion 216 and the main surface 221. For example, the top surface of the convex portion 216 may be recessed in the main surface 221.
[0043] The two slide plates 225 are an example of a slide portion that slides relative to the lock member 21 between a position where it enters the space S between the claw portion 214 and the base portion 211 and a position where it does not enter the space S. The two slide plates 225 are spaced apart from each other in the width direction (X) and are formed along the axial direction (Z) of the handle portion 11.
[0044] 7, 11 and 12 show a state in which the convex portion 216 of the locking member 21 abuts against the end portion on the head direction (Z(H)) side of the opening edge portion 228 of the sliding member 22. In this state, the sliding member 22 cannot move in a direction away from the locking member 21 (grip direction (Z(G))). That is, the state shown in Figs. 7 and 12 is a state in which the sliding member 22 is positioned furthest from the locking member 21 on the grip direction (Z(G)) side. This state may be referred to as the unlocked state below.
[0045] 12, in the unlocked state, the sliding plate 225 does not enter the space S between the claws 214 and the base 211. In addition, the minimum distance d2 between the two claws 214 in the natural state (when the handle 11 is not inserted into the attachment 20) is smaller than the outer diameter of the handle 11. For this reason, when the handle 11 is inserted into the attachment 20, the claws 214 bend so that their tips move outward, and the claws 214 pinch the handle 11 by their elasticity, making it difficult for the attachment 20 to slip relative to the handle 11.
[0046] <6.How to use> The configuration of the wearing device 20 according to one embodiment of the present invention has been described above. Next, a method of using the wearing device 20 according to one embodiment of the present invention will be described.
[0047] In the unlocked state described above, the user can move the attachment 20 toward the head (Z(H)) relative to the handle portion 11, and further slide the slide member 22 toward the locking member 21, thereby putting the cleaning tool 1 with attachment into a locked state in which rotation of the handle portion 11 around the rotation axis L2 relative to the cleaning head 12 is restricted.
[0048] Fig. 13 is an explanatory diagram showing the appearance of the cleaning tool with attachment 1 in the locked state. Fig. 14 is a cross-sectional view of the cleaning tool with attachment 1 in the locked state. As shown in Figs. 13 and 14, the locked state is a state in which the base 211 of the locking member 21 overlaps with both the handle portion 11 and the connecting portion 14, and the sliding member 22 is located closest to the head direction (Z(H)) side with respect to the locking member 21.
[0049] In this locked state, the claw portion 214 of the locking member 21 fits into the gap H between the handle connecting portion 142 and the bottom portion 135 of the handle portion 11 (see FIG. 4), and abuts against the bottom portion 135 of the handle portion 11 as shown in FIG. 14. Also, as shown in FIG. 14, in the locked state, the sliding plate 225 of the sliding member 22 enters the space S between the claw portion 214 and the base portion 211. Therefore, the tip of the claw portion 214 is unlikely to bend outward, and is unlikely to come out of the gap H. Note that, as shown in FIG. 14, even in the locked state, the tip of the sliding plate 225 of the sliding member 22 is spaced apart from the end portion of the base portion 211 on the head direction (Z(H)) side.
[0050] In addition, in the process of reaching the locked state, the convex portion 216 of the locking member 21 climbs over the protrusion 228a formed on the opening edge portion 228 of the sliding member 22, and the convex portion 216 becomes positioned on the grip direction (Z(G)) side of the protrusion 228a as shown in FIG. 13.
[0051] Even in this locked state, the handle 11 can rotate around the rotation axis L1 relative to the cleaning head 12. However, because the base 211 overlaps both the handle 11 and the connecting part 14, the position of the handle 11 relative to the connecting part 14 is fixed by the base 211, and therefore rotation of the handle 11 around the rotation axis L2 (see FIG. 5) relative to the cleaning head 12 is restricted.
[0052] In the locked state, the user can return the cleaning tool with attachment 1 to the unlocked state by holding the finger hook 226 and applying a force in the grip direction (Z(G)) to the attachment 20. Specifically, when the user holds the finger hook 226 and applies a force in the grip direction (Z(G)) to the attachment 20, the sliding member 22 moves in the grip direction (Z(G)) relative to the locking member 21, and the sliding plate 225 comes out of the space S. Thereafter, the claw portion 214 bends toward the space S, disengaging the claw portion 214 from the gap H, and the sliding member 22 and the locking member 21 move together in the grip direction (Z(G)).
[0053] <7. Effects> According to the above-described cleaning tool with attachment 1 according to one embodiment of the present invention, various actions and effects can be obtained. For example, according to one embodiment of the present invention, in a locked state in which the base 211 of the locking member 21 overlaps both the handle 11 and the connecting portion 14, the claw portion 214 abuts against the bottom portion 135, which is an example of a portion of the handle 11 facing the head direction (Z(H)). Therefore, the attachment 20 is unlikely to move toward the grip direction (Z(G)). One embodiment of the present invention is also useful in that such locking of the attachment 20 can be realized without changing the design of the cleaning tool 10 including the handle 11 by designing the attachment 20 so that the claw portion 214 abuts against a portion of the existing handle 11 facing the head direction (Z(H)). In addition, since the attachment 20 is detachable from the cleaning tool 10, a user who already owns the cleaning tool 10 can obtain the cleaning tool with attachment 1 according to one embodiment of the present invention by obtaining the attachment 20 and attaching the attachment 20 to the cleaning tool 10.
[0054] In one embodiment of the present invention, a space S is formed between the claws 214 and the base 211. Furthermore, the minimum distance d2 between the two claws 214 in the natural state (a state in which the handle 11 is not inserted into the attachment 20) may be smaller than the outer diameter of the handle 11. In this case, when the handle 11 is inserted into the attachment 20, the claws 214 bend so that their tips move outward, and the claws 214 pinch the handle 11 by their elasticity, making it difficult for the attachment 20 to slip relative to the handle 11.
[0055] Moreover, in one embodiment of the present invention, a slide plate 225 is provided that slides relative to the locking member 21 between a position where it enters the space S between the claw portion 214 and the base portion 211 and a position where it does not enter the space S. In the locked state, the slide plate 225 enters the space S, making it difficult for the tip of the claw portion 214 to bend outward. As a result, it is possible to make it difficult for the claw portion 214 to come out of engagement with the gap H.
[0056] Furthermore, in one embodiment of the present invention, in the locked state, the tip of the slide plate 225 of the slide member 22 is spaced apart from the end of the base 211 on the head direction (Z(H)) side. With this configuration, the contact area between the slide plate 225 and the claw portion 214 is reduced, making it easier for the slide plate 225 to slide. Also, the slide stroke of the slide plate 225 is reduced, improving operability.
[0057] Moreover, in one embodiment of the present invention, the base 211 has a shape that becomes thinner toward the head direction (Z(H)). More specifically, the thickness of the base 211 in the front-rear direction becomes smaller toward the head direction (Z(H)). With this configuration, when the handle 11 rotates around the rotation axis L1 relative to the cleaning head 12 in the locked state, the base 211 is less likely to come into contact with the cleaning head 12, so that the rotatable range of the handle 11 can be secured widely.
[0058] Moreover, in one embodiment of the present invention, locking member 21 has engagement portion 215, and protrusions 228a are formed on portions of opening edge portion 228 of slide member 22 that face each other along the Z-axis direction. Convex portion 216 formed on engagement portion 215 rides over protrusion 228a during state transition between the locked state and the unlocked state, allowing the user to obtain a clicking sensation.
[0059] In one embodiment of the present invention, the protrusion 216 has an elliptical cylindrical shape, and the end of the opening edge 228 on the head direction (Z(H)) side has a semi-elliptical shape. Therefore, when the locking member 21 and the sliding member 22 are assembled, as shown in FIG. 11, the protrusion 216 comes into surface contact with the end of the opening edge 228 on the head direction (Z(H)) side. As a result, it is considered that stress concentration is alleviated and durability is improved compared to the case where the protrusion 216 and the opening edge 228 are in point contact or line contact. In addition, instead of the protrusion 216, a protrusion 218 having a tapered shape in which the protrusion amount decreases toward the grip direction (Z(G)) side may be formed. According to the tapered shape, the protrusion 216 can be easily inserted inside the sliding member 22, so that the ease of assembly of the locking member 21 and the sliding member 22 can be improved.
[0060] In one embodiment of the present invention, the finger hook 226 is formed on the main surface 221 on which the opening 227 is formed. When the finger hook 226 is formed on the side surface 222, the user holds the slide member 22 so as to sandwich the two finger hooks 226. In this case, a force is generated to close the opening 227 inward. Therefore, when the user tries to transition the state of the attachment-equipped cleaning tool 1 from the locked state to the unlocked state, the convex portion 216 is difficult to get over the protrusion 228a. In this regard, in one embodiment of the present invention, the finger hook 226 is formed on the main surface 221 as described above, so that the user can transition the state of the attachment-equipped cleaning tool 1 from the locked state to the unlocked state without such a hindrance. In addition, the finger hook 226 is formed on the main surface 221, which is expected to have the effect of reducing the amount of twisting of the wrist by the user and making it difficult for the user's middle finger to little finger to be pinched between the slide member 22 and the handle portion 11.
[0061] Moreover, in one embodiment of the present invention, there is a step between the top surface of convex portion 216 and main surface 221. For example, the top surface of convex portion 216 may be recessed into main surface 221. With this configuration, when a user tries to move sliding member 22 in the grip direction (Z(G)) while holding sliding member 22 by finger hook portion 226, the user's fingers of wearing tool 20 are unlikely to be pinched between convex portion 216 and main surface 221.
[0062] In one embodiment of the present invention, the inner diameter of through-hole 223 is substantially the same as the outer diameter of handle 11, and a curved surface R may be formed along the circumferential direction on the edge of through-hole 223 on the grip direction (Z(G)) side. In this configuration, the user's fingers are less likely to be pinched between slide member 22 and handle 11 when the user moves wearing tool 20 in the grip direction (Z(G)).
[0063] <8. Variations> An embodiment of the present invention has been described above. In the following, some modified examples of the above-described embodiment will be described. Note that each modified example described below may be applied alone to the above-described embodiment, or may be applied in combination to the above-described embodiment. Also, each modified example may be applied in place of the configuration of the above-described embodiment, or may be applied in addition to the configuration of the above-described embodiment.
[0064] (First Modification) 15 is an explanatory diagram showing a wearing tool 30 according to a first modified example. As shown in FIG. 15, the wearing tool 30 according to the first modified example includes a base part 311 having a shape surrounding the outer periphery of the handle part 11.
[0065] The base 311 has a first base element 3111 and a second base element 3116. The first base element 3111 and the second base element 3116 are connected via a hinge 312 that forms a rotation axis along the axial direction (Z). The second base element 3116 rotates around the rotation axis relative to the first base element 3111, causing the base 311 to open and close.
[0066] The first base element 3111 and the second base element 3116 have a convex portion or a concave portion on the inner periphery or outer periphery as an engagement portion that engages with each other when the base 311 is closed. In the example shown in FIG. 15, the first base element 3111 has a convex portion along the axial direction (Z) as an engagement portion on the outer periphery surface of the end portion opposite the hinge 312 in the circumferential direction. The second base element 3116 has a concave portion (not shown) along the axial direction (Z) as an engagement portion on the inner periphery surface of the end portion opposite the hinge 312 in the circumferential direction. When the base 311 is closed, the engagement portion 3112 of the first base element 3111 and the engagement portion of the second base element 3116 engage with each other to maintain the base 311 closed.
[0067] The first base element 3111 and the second base element 3116 are formed with claw portions 314 having a region that protrudes toward the inner periphery of the base portion 311 .
[0068] Next, a method of using the attachment 30 according to the first modified example will be described with reference to Figs. 16 to 18. Fig. 16 is an explanatory diagram showing the external configuration of the attachment-equipped cleaning tool 2 in an unlocked state. Fig. 17 is an explanatory diagram showing the external configuration of the attachment-equipped cleaning tool 2 in a locked state. Fig. 18 is a cross-sectional view of the attachment-equipped cleaning tool 2 in a locked state.
[0069] 16, in the unlocked state, the attachment 30 is separated from the position where the handle 11 and the connecting portion 14 overlap. In the unlocked state, the two claws 314 pinch the handle 11, making it difficult for the attachment 30 to slip relative to the handle 11.
[0070] As shown in Fig. 17, when the user moves the attachment 30 in the head direction (Z(H)) to a position where the handle 11 and the connecting part 14 overlap, the cleaning tool with attachment 2 enters a locked state. In the locked state, as shown in Fig. 18, the claw part 314 abuts against the bottom part 135 of the handle 11. Therefore, the attachment 30 is difficult to move in the grip direction (Z(G)).
[0071] (Second Modification) 19 is an explanatory diagram showing a wearing tool 40 according to a second modified example. As shown in FIG. 19, the wearing tool 40 according to the second modified example includes a base part 411 and a ring 420 having a shape surrounding the outer periphery of the handle part 11.
[0072] The base 411 has a first base element 4111 and a second base element 4116. The first base element 4111 and the second base element 4116 are connected via a hinge 412 that forms a rotation axis along the axial direction (Z). The second base element 4116 rotates around the rotation axis relative to the first base element 4111, causing the base 411 to open and close.
[0073] The first base element 4111 and the second base element 4116 have a convex portion or a concave portion on the inner or outer periphery side as an engagement portion that engages with each other when the base 411 is closed. In the example shown in Fig. 19, the first base element 4111 has a convex portion 4112 and a concave portion 4113 along the axial direction (Z) as engagement portions at different positions in the circumferential direction. The second base element 4116 has a convex portion 4118 along the axial direction (Z) as an engagement portion on the inner periphery surface of the end portion opposite the hinge 412.
[0074] The first base element 4111 and the second base element 4116 are formed with claw portions 414 having a region that protrudes toward the inner periphery of the base portion 411 .
[0075] A slit 421 is formed along the axial direction (Z) in the ring 420. The inner diameter of the ring 420 may be equal to or smaller than the outer diameter of the handle portion 11.
[0076] Next, a method of using the attachment 40 according to the second modified example will be described with reference to Figs. 20 to 22. Fig. 20 is an explanatory diagram showing the external configuration of the attachment-equipped cleaning tool 3 in an unlocked state. Fig. 21 is an explanatory diagram showing the external configuration of the attachment-equipped cleaning tool 3 in a locked state. Fig. 22 is a cross-sectional view of the attachment-equipped cleaning tool 3 in a locked state.
[0077] 20, in the unlocked state, the attachment 40 is spaced from the position where the handle 11 and the connecting part 14 overlap. Furthermore, the protrusion 4112 of the first base element 4111 engages with the protrusion 4118 of the second base element 4116, temporarily locking the base 411 in the closed state. In this unlocked state, the ring 420 is pressed against the outer circumferential surface of the handle 11 while being spread apart by the presence of the slits 421, so that the attachment 40 is less likely to slip relative to the handle 11.
[0078] As shown in Fig. 21, when the user moves the attachment 40 in the head direction (Z(H)) to a position where the handle 11 and the connecting part 14 overlap, and engages the convex part 4118 of the second base element 4116 with the concave part 4113 of the first base element 4111, the cleaning tool with attachment 3 enters a locked state. In the locked state, as shown in Fig. 22, the claw part 414 abuts against the bottom part 135 of the handle 11. Therefore, the attachment 40 is less likely to move in the grip direction (Z(G)).
