Description

[Technical field]

[0001] The present invention relates to a cleaning tool and a cleaning tool joint for use with the cleaning tool. [Background technology]

[0002] Conventionally, an adhesive tape cleaning tool described in Patent Document 1 is known as a cleaning tool. The adhesive tape cleaning tool includes a support grip that supports an adhesive roll at its tip end, and an extension rod that is inserted into the base end of the support grip. The support grip is formed at its base end with a cylindrical extension rod hole into which the extension rod can be inserted, and a hook hole that passes radially through the extension rod hole. The extension rod is provided at its tip with an engagement hook that can engage with the hook hole.

[0003] According to the adhesive tape cleaning tool configured as above, the extension rod can be connected to the support grip by inserting the extension rod into the extension rod hole and engaging the engaging hook with the hook hole. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2016-32627 A Summary of the Invention [Problem to be solved by the invention]

[0005] In the adhesive tape cleaning tool described in Patent Document 1, the extension rod is inserted into the extension rod hole and engaged with the engagement hook to connect the extension rod to the support grip. However, in this connection method, a gap may occur between the inner peripheral surface of the extension rod hole and the outer peripheral surface of the extension rod due to manufacturing tolerances, etc. This causes a problem that the extension rod may wobble relative to the support grip.

[0006] Therefore, an object of the present invention is to provide a cleaning tool joint and a cleaning tool that can prevent a portion provided on the tip side from wobbling relative to a portion provided on the base end side. [Means for solving the problem]

[0007] The cleaning tool joint of the present invention is a cleaning tool joint used in a cleaning tool for connecting and fixing a part provided on the tip side and a part provided on the base side of the cleaning tool, wherein at least one of the part provided on the tip side and the part provided on the base side is a tubular body and comprises a main body portion inserted into the inside of the tubular body, the main body portion comprises a base portion having an outer diameter smaller than the inner diameter of the tubular body, and a protrusion portion protruding radially outward from the outer peripheral surface of the base, the main body portion has an outer diameter larger than the inner diameter of the tubular body at at least two points separated by a direction including an axial component of the outer peripheral surface of the part, and the protrusion portion is capable of deforming by abutting against the inner peripheral surface of the tubular body.

[0008] With this configuration, when the main body portion is inserted into the tube, the protrusion portion can abut and deform against the inner surface of the tube, so that the main body portion is in close contact with the inner surface of the tube at at least two points spaced apart in a direction that includes the axial component, thereby preventing the tube from wobbling.

[0009] The protrusion may be provided so as to extend in a direction intersecting both the axial direction and the circumferential direction of the base portion.

[0010] According to this configuration, the protrusion extends in a direction intersecting the axial direction and circumferential direction of the base, making it easier to insert the main body into the tube compared to a case in which the protrusion extends in the circumferential direction.

[0011] The protrusion may be a protrusion that extends substantially around the entire circumference of the main body.

[0012] According to this configuration, the main body is in close contact with the inner circumferential surface of the tube over substantially the entire circumference, so that the contact force is less likely to vary in the circumferential direction, thereby preventing the tube from wobbling.

[0013] The protrusion may be a spiral protrusion provided on the outer circumferential surface of the base.

[0014] According to this configuration, since the protrusion is spiral, it is easy to insert the main body into the pipe, and the protrusion can reliably abut against the inner peripheral surface of the pipe.

[0015] In addition, the base portion may have an area in the axial direction where no protrusions are provided.

[0016] According to this configuration, an area is formed in the base where no protrusions are provided along the axial direction, so that when the main body is removed from the mold for molding, it becomes easier to remove the main body from the mold.

[0017] In addition, the protrusion portion may include a base portion protruding radially outward from the outer peripheral surface of the base portion, and a deforming portion protruding radially outward from the outer peripheral surface of the base portion, and the deforming portion may be capable of deforming by abutting against the inner peripheral surface of the tube body.

[0018] According to this configuration, the deformation portion provided at the tip portion of the protrusion deforms, so that the protrusion can reliably come into contact with the inner peripheral surface of the tube.

[0019] The cleaning tool joint of the present invention is used for a cleaning tool and is for connecting and fixing a pipe provided on the tip side and a pipe provided on the base end side of the cleaning tool, and comprises a tip main body portion inserted into the pipe provided on the tip side and a base main body portion inserted into the pipe provided on the base end side, the tip main body portion comprises a tip base portion having an outer diameter smaller than the inner diameter of the pipe provided on the tip side, and a tip protrusion portion protruding radially outward from an outer circumferential surface of the tip base portion, and the tip main body portion has a tip protrusion portion at least two points separated in a direction including an axial component of the outer circumferential surface at the portion. the outer diameter of the proximal end body is larger than the inner diameter of the tube provided on the distal end side, and the proximal end protrusion is capable of deforming by abutting against the inner peripheral surface of the tube provided on the distal end side, and the proximal end main body comprises a proximal end base having an outer diameter smaller than the inner diameter of the tube provided on the proximal end side, and a proximal end protrusion protruding radially outward from the outer peripheral surface of the proximal end base, and the proximal end main body has an outer diameter larger than the inner diameter of the tube provided on the proximal end side at at least two points spaced apart in a direction including the axial component of the outer peripheral surface at the portion comprising the proximal end protrusion, and the proximal end protrusion is capable of deforming by abutting against the inner peripheral surface of the tube provided on the proximal end side.

[0020] With this configuration, the tip main body portion is in close contact with the inner surface of the tube provided on the tip side, and the base main body portion is in close contact with the inner surface of the tube provided on the base end, at at least two points spaced apart in a direction that includes the axial component, thereby preventing the tube provided on the tip side from wobbling relative to the tube provided on the base end.

[0021] In addition, the tip protrusion portion is arranged to extend in a direction intersecting both the axial direction and the circumferential direction of the tip base portion, and the base end protrusion portion can be arranged to extend in a direction intersecting both the axial direction and the circumferential direction of the base end base portion.

[0022] With this configuration, the tip protrusion and the base protrusion extend in a direction intersecting both the axial direction and the circumferential direction, making it easier to insert them into the tube provided on the tip side and the tube provided on the base side compared to when the tip protrusion and the base protrusion extend in the circumferential direction.

[0023] In addition, the tip protrusion portion can be a protrusion arranged to extend approximately around the circumference of the tip main body portion, and the base end protrusion portion can be a protrusion arranged to extend approximately around the circumference of the base end main body portion.

[0024] With this configuration, the tip main body portion is in close contact with the inner surface of the tip tube around approximately the entire circumference, and the base main body portion is in close contact with the inner surface of the base tube around approximately the entire circumference, so that the adhesion force is less likely to vary in the circumferential direction, thereby preventing the tip tube and the base tube from wobbling.

[0025] The tip protrusion may be a protrusion provided in a spiral shape on the outer peripheral surface of the tip base portion, and the base protrusion may be a protrusion provided in a spiral shape on the outer peripheral surface of the base base portion.

[0026] With this configuration, the tip protrusion and the base protrusion are spirally shaped, making it easy to insert the tip main body into the tip tube and the base main body into the base tube, and they can reliably abut against the inner surfaces of the tip tube and the base tube.

[0027] In addition, a region where the tip protrusion is not provided along the axial direction can be formed in the tip main body portion, and a region where the base protrusion is not provided along the axial direction can be formed in the base main body portion.

[0028] With this configuration, when the tip body portion and the base body portion are removed from the mold and molded, there is an area in the tip body portion where the tip protrusion is not provided along the axial direction, and an area in the base body portion where the base protrusion is not provided along the axial direction, making it easier to remove the tip body portion and the base body portion from the mold.

[0029] The cleaning tool of the present invention further comprises a cleaning tip portion provided at a tip end thereof and having a cleaning main body portion that comes into contact with an object to be cleaned and cleans the object to be cleaned, a grip portion provided at a base end thereof and that is gripped when cleaning, and the cleaning tool joint according to any one of claims 1 to 5 that connects the cleaning tip portion and the grip portion.

[0030] With this configuration, a cleaning tool can be obtained in which the portion provided on the tip side is prevented from wobbling relative to the portion provided on the base side. Effect of the Invention

[0031] Advantageous Effects of Invention According to the present invention, it is possible to obtain a cleaning tool joint and a cleaning tool that can prevent a portion provided on the tip side from wobbling relative to a portion provided on the base end side. [Brief description of the drawings]

[0033] An embodiment of the present invention will be described with reference to Figures 1 to 13. In the following description, the tip end and base end will be described based on the directions of the cleaning tool A as a whole shown in Figure 1 (except for individual descriptions of each part).

[0034] As shown in FIG. 1, the cleaning tool A includes a cleaning tip 1 provided at the tip side, a grip part 2 provided at the base end, a cleaning tool joint 3 connecting the cleaning tip 1 and the grip part 2, and a hanging handle part 4 connected to the base end of the grip part 2. The cleaning tip 1 is configured so that a cleaning main body part such as an adhesive roll R that comes into contact with an object to be cleaned and removes dirt and the like can be attached to it. The grip part 2 is a part that a user holds when cleaning. Furthermore, such a cleaning tool A maintains a state in which each part is connected in normal use. That is, the connection between each part of the cleaning tool A is not released in normal use.

[0035] The cleaning tip 1 includes a head 11 to which the cleaning body is attached, and a tip extension 12 extending from the head 11 toward the base end. The head 11 is cylindrical or columnar, and is rotatably connected to the tip extension 12. The tip extension 12 is a rod-shaped portion bent to match the shape of the head 11 so as to support the head 11 at the radial center. Specifically, the tip extension 12 is a rod-shaped portion whose base end has an outer diameter smaller than the inner diameter of the grip 2, and whose base end has an outer diameter larger than the inner diameter of an insertion port 3a formed in a cleaning tool joint 3 described later. In the cleaning tip 1 of this embodiment, the head 11 is made of resin, and the tip extension 12 is made of metal.

[0036] The grip portion 2 is a columnar portion in which at least the tip and base ends are formed to be hollow. The grip portion 2 of this embodiment is formed to be hollow from the tip to the base end. The grip portion 2 is a cylindrical body with a circular interior. In other words, the grip portion 2 of this embodiment is a single tube. The grip portion 2 of this embodiment is made of metal.

[0037] As shown in Fig. 2, the hanging handle part 4 is a part that is inserted through a hook or the like and supports the entire cleaning tool A. As shown in Fig. 2, the hanging handle part 4 includes a hanging handle main body part 41 having a hanging hole 4a through which a hook or the like can be inserted, and a hanging handle connecting joint part 42 provided on the base end side of the hanging handle main body part 41. Such a hanging handle part 4 is connected to the grip part 2 by inserting the hanging handle connecting joint part 42 into the base end part of the grip part 2.

[0038] When the hanging hand connecting joint 42 is considered to be a separate part from the hanging hand main body 41, it can be said that the hanging hand connecting joint 42 connects and fixes the grip part 2, which is a tubular body provided at the tip side, to the hanging hand main body 41. Specifically, the hanging hand connecting joint 42 has its tip side inserted into the grip part 2, and the hanging hand main body 41 joined to the base end of the hanging hand connecting joint 42 at its base end. The hanging hand connecting joint 42 also includes a hanging hand connecting base 421 whose outer diameter is smaller than the inner diameter of the base end of the grip part 2, and a hanging hand connecting protrusion 422 that protrudes radially outward from the outer circumferential surface of the hanging hand connecting base 421. Furthermore, the hanging handle connecting joint 42 has an outer diameter larger than the inner diameter of the base end of the grip part 2 at at least two points spaced apart in a direction including an axial component at a portion including the hanging handle connecting protrusion 422, and the hanging handle connecting protrusion 422 can abut and deform on the inner peripheral surface of the base end of the grip part 2. Also, the hanging handle connecting joint 42 has a hanging handle pin insertion hole 42a, which is a hole penetrating in the radial direction. Furthermore, the hanging handle part 4 of this embodiment is made of resin.

[0039] Specifically, the hanging handle connection protrusion 422 is provided on the outer peripheral surface of the hanging handle connection base 421 so as to extend in a direction intersecting both the axial direction and the circumferential direction. The hanging handle connection protrusion 422 is a protrusion provided over most of the entire circumference of the outer peripheral surface of the hanging handle connection base 421. In addition, in the hanging handle connection joint 42 of this embodiment, an area in which no protrusion is formed over the axial direction is formed in a part of the circumferential direction in order to remove it from the mold. Furthermore, the hanging handle connection protrusion 422 is a protrusion provided in a spiral shape on the outer peripheral surface of the hanging handle connection base 421.

[0040] Such a hanging hand part 4 is connected to the grip part 2 by inserting the hanging hand joint part 42 into the grip part 2. Specifically, the hanging hand joint part 42 is inserted by rotating it as if it were screwed into the base end of the grip part 2, and the hanging hand joint part 422 is deformed so that it abuts on the inner peripheral surface of the grip part 2 and reduces in diameter. This deformation generates a restoring force toward the outside of the diameter of the hanging hand joint part 422. Therefore, since the hanging hand joint part 422 is in close contact with the inner peripheral surface of the grip part 2, the hanging hand part 4 is attached in a state in which it is prevented from wobbling relative to the grip part 2. In addition, by inserting the hanging hand joint part 42 into the grip part 2, and then providing a pin P1 so that it penetrates the grip part 2 in the radial direction and passes through the hanging hand pin insertion hole 42a, the hanging hand part 4 can be prevented from falling off the grip part 2.

[0041] As shown in Figs. 3 to 11, the cleaning tool joint 3 connects the cleaning tip 1 and the grip 2. That is, the cleaning tip 1 is connected to the tip side of the cleaning tool joint 3, and the grip 2 is connected to the base end side, thereby connecting the cleaning tip 1 and the grip 2. Specifically, the cleaning tool joint 3 includes a main body 31 that is inserted into the tip of the grip 2, which is a tube, and a tube end abutment 32 that is connected to the tip of the main body 31. The cleaning tool joint 3 also has an insertion port 3a that allows the base end of the tip extension 12 to be inserted from the tip to the base end. The insertion port 3a in this embodiment is a hole that penetrates in the axial direction. The inner diameter of the insertion port 3a is smaller than the outer diameter of the base end of the tip extension 12. Furthermore, the cleaning tool joint 3 connects the cleaning tip 1 and the grip 2 in an undetachable manner. That is, in normal use, the connection between the cleaning tip 1 and the grip part 2 is not released.

[0042] The cleaning tip 1 is connected to the cleaning tool joint 3 by inserting the tip extension 12 into the insertion opening 3a. Specifically, since the outer diameter of the tip of the tip extension 12 is larger than the inner diameter of the insertion opening 3a, when the tip extension 12 is inserted into the insertion opening 3a, the tip extension 12 advances toward the base end while pushing the inner wall of the insertion opening 3a radially outward. Therefore, when the tip extension 12 is inserted into the insertion opening 3a, the inner wall of the insertion opening 3a comes into close contact with the tip extension 12, so that the cleaning tip 1 is connected to the cleaning tool joint 3 in a state in which wobbling is suppressed (see FIG. 12).

[0043] The main body 31 includes a base 311 having an outer diameter smaller than the inner diameter of the tip of the gripping portion 2, and a protrusion 312 protruding radially outward from the outer circumferential surface of the base 311. The outer diameter of the portion of the main body 31 where the protrusion 312 is provided is larger than the inner diameter of the tip of the gripping portion 2. Furthermore, the main body 31 includes a pin insertion portion 313 at its base end, in which a joint pin insertion hole 313a, which is a hole through which the pin P2 (see FIG. 12) can be inserted, is formed.

[0044] The base 311 is a rod-shaped body extending in the axial direction. The base 311 is a rod-shaped body having a smaller inner diameter than the tip of the gripping part 2. The base 311 of this embodiment is a rod-shaped body extending from the pin insertion part 313 to the tube end abutment part 32. Furthermore, the base 311 of this embodiment is formed with a hole (insertion port 3a) penetrating in the axial direction from the tip side to the base end side. The base 311 is a cylinder with a substantially constant outer diameter from the tip to the base end.

[0045] The protrusion 312 is a protrusion that protrudes radially outward from the outer circumferential surface of the base 311. The protrusion 312 is deformable by contacting with the inner circumferential surface of the tip of the grip 2. Specifically, the protrusion 312 includes a base portion 3121 that protrudes radially outward from the outer circumferential surface of the base 311, and a deformation portion 3122 that protrudes radially outward from the outer circumferential surface of the base 3121, and the deformation portion 3122 is deformable by contacting with the inner circumferential surface of the tip of the grip 2. The protrusion 312 of this embodiment is a protrusion that extends in a direction intersecting both the axial direction and the circumferential direction of the base 311. The protrusion 312 is a protrusion that is provided to extend approximately around the circumference of the main body 31 in the circumferential direction. In addition, in the protrusion 312 of this embodiment, a region 312a where a protrusion (deformed portion 3122) is not formed along the axial direction is formed in a part of the circumferential direction in order to allow the protrusion 312 to be removed from the mold, and in this embodiment, the outer diameter of the region 312a is smaller than the inner diameter of the gripping portion 2 (see FIG. 4). Furthermore, the protrusion 312 is a protrusion provided in a spiral shape on the outer circumferential surface of the base 311. That is, the protrusion 312 is a protrusion provided on the outer circumferential surface of the base 311 so as to extend over multiple revolutions in a direction intersecting both the axial direction and the circumferential direction. Furthermore, the base portion 3121 and the deformed portion 3122 of this embodiment are integrally molded.

[0046] 11, base portion 3121 is connected to the outer circumferential surface of base portion 311 and extends radially outward from the outer circumferential surface of base portion 311. Base portion 3121 has, on its outer circumferential surface, base flat portion 3121a extending substantially parallel to the axis. Base flat portion 3121a is a flat surface having a certain width in the axial direction. Base flat portion 3121a is provided over the entire outer circumferential surface of base portion 3121.

[0047] The deformable portion 3122 is a portion that protrudes radially outward from the base portion 3121. The deformable portion 3122 is provided so as to protrude radially outward from the base flat portion 3121a. Furthermore, the deformable portion 3122 has a shape in which the tip portion (the end portion on the radially outer side) is thinner (has a shorter axial length) than the base portion (the portion connected to the base flat portion 3121a). The tip portion of the deformable portion 3122 of this embodiment is arc-shaped. Furthermore, the deformable portion 3122 of this embodiment is relatively softer than the tip portion of the grip portion 2, and is therefore easily deformed. Specifically, the tip portion of the deformable portion 3122 can be deformed so as to be crushed toward the base end side when the tip portion comes into contact with the inner circumferential surface of the grip portion 2. This deformation generates a restoring force to the radially outward in the deformable portion 3122.

[0048] The pipe end abutment portion 32 is a portion that can abut against the end surface on the base end side of the gripping portion 2. Specifically, the pipe end abutment portion 32 is a portion whose outer diameter is larger than the inner diameter of the gripping portion 2. Moreover, the pipe end abutment portion 32 is a portion that protrudes radially outward from the outer circumferential surface of the tip portion of the base portion 311. In this embodiment, the pipe end abutment portion 32 is a protrusion that protrudes radially outward around one circumferential circumference of the base portion 311. Specifically, the pipe end abutment portion 32 includes an annular abutment portion 321 that protrudes radially outward from the outer circumferential surface of the base portion 311, and a positioning portion 322 that protrudes from the annular abutment portion 321 toward the base end side.

[0049] The annular contact portion 321 is an annular portion whose outer diameter is larger than the inner diameter of the base end portion. The annular contact portion 321 has an inner end portion connected to the outer circumferential surface of the base portion 311. The annular contact portion 321 is provided substantially coaxially with the base portion 311. The outer diameter of the annular contact portion 321 is substantially equal to the outer diameter of the grip portion 2. Such an annular contact portion 321 can close the tip portion of the grip portion 2.

[0050] The positioning portion 322 is a plurality of protrusions extending from the annular contact portion 321 toward the base end side. When inserted into the grip portion 2, the plurality of positioning portions 322 abut against the inner circumferential surface of the grip portion 2, and suppress the grip portion 2 from shifting relative to the tube end abutment portion 32. In addition, since the positioning portion 322 extends from the annular contact portion 321 toward the base end side, it is possible to reinforce the annular contact portion 321 and suppress deformation of the annular contact portion 321 such as entering into the inside of the grip portion 2.

[0051] The cleaning tool joint 3 configured as above has a tip extension 12 connected to its tip side and a grip 2 connected to its base end side. Specifically, the tip extension 12 is connected to the tip of the cleaning tool joint 3 by inserting the tip extension 12 into the insertion opening 3a. Also, the grip 2 is connected to the base end side of the cleaning tool joint 3 by inserting the grip 2.

[0052] 13, the inner diameter of the insertion opening 3a is smaller than the outer diameter of the tip extension 12, so the inner wall of the insertion opening 3a of the base 311 is in close contact with the outer circumferential surface of the inserted tip extension 12. Therefore, the cleaning tip 1 is connected to the cleaning tool joint 3 in a state in which wobbling is suppressed.

[0053] Furthermore, since the outer diameter of the main body 31 is larger than the inner diameter of the gripping portion 2 at the portion where the protrusion 312 is provided, the protrusion 312 adheres closely to the inner peripheral surface of the gripping portion 2. Specifically, the deformation portion 3122 is pushed radially inward by the inner peripheral surface of the gripping portion 2 and deforms. The outer peripheral surface of the deformation portion 3122 deforms into a shape that fits the inner peripheral surface of the gripping portion 2 and adheres closely to the inner peripheral surface of the gripping portion 2.

[0054] Once the main body 31 is inserted into the grip portion 2, a pin P2 is inserted so as to penetrate the grip portion 2 and the pin insertion portion 313. The pin P2 can prevent the main body 31 from falling off the grip portion 2.

[0055] According to the cleaning tool joint 3 configured as described above, when the main body 31 is inserted into the tube (grip portion 2), the protrusions 312 can abut and deform against the inner surface of the tube, so that the main body 31 is in close contact with the inner surface of the tube at at least two points spaced apart in a direction including the axial component, making it difficult for any point to float relative to the inner surface of the tube, and preventing the tube from wobbling.

[0056] In addition, since the protrusion 312 extends in a direction intersecting both the axial direction and the circumferential direction of the base 311, the resistance experienced by the cleaning tool joint 3 during insertion is smaller than when the protrusion 312 extends in the circumferential direction, making it easier to insert the main body 31 into the tube (grip portion 2).

[0057] Furthermore, since the main body portion 31 is in close contact with the inner surface of the tube (grip portion 2) over approximately the entire circumference (specifically, the section in which the deformation portion 3122 is provided), the force applied radially to the tube can be reliably received by the main body portion 31, thereby preventing the tube from wobbling.

[0058] Furthermore, since the protrusion 312 is spiral, the main body 31 can be easily inserted into the tube (the grip portion 2), and the protrusion 312 can reliably come into contact with the inner peripheral surface of the tube.

[0059] Furthermore, since an area 312a is formed in the base 311 where no protrusions (specifically, the deformed portions 3122) are provided along the axial direction, when the main body portion 31 is removed from a mold and molded, the main body portion 31 can be easily removed from the mold.

[0060] Furthermore, since the deformation portion 3122 provided at the tip portion of the protrusion 312 is deformed, the protrusion 312 can reliably come into contact with the inner circumferential surface of the tube (the grip portion 2).

[0061] Furthermore, the protrusion 312 includes a base portion 3121 provided so as to protrude radially outward from the outer circumferential surface of the base 311, and a deformation portion 3122 protruding radially outward from the outer circumferential surface of the base portion 3121, and since the axial width of the deformation portion 3122 is smaller than the axial width of the outer circumferential surface of the base portion 3121, the deformation portion 3122 can be deformed with less force than when the base portion 3121 is deformed. Therefore, the main body portion 31 can be easily inserted into the tube (the grip portion 2).

[0062] Furthermore, since the shape of the radially outer tip of the protrusion 312 (the tip of the deformation portion 3122) is an arc shape, it can reliably come into contact with the inner circumferential surface of the tube (the grip portion 2) and be deformed.

[0063] Furthermore, the main body 31 has protrusions 312 formed on the front and rear surfaces based at least on the direction of movement during cleaning (in this embodiment, the direction of movement when the adhesive roll R is rotated around the axis of the head 11), so that even when a load is applied to the head 11 during cleaning, the gripping portion 2 is less likely to wobble relative to the cleaning tip 1.

[0064] Furthermore, according to the cleaning tool A configured as described above, it is possible to obtain a cleaning tool A in which the part provided on the tip side is prevented from wobbling relative to the part provided on the base side.

[0065] Although the cleaning tool A and the cleaning tool joint 3 of the present invention have been described above using examples, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the present invention.

[0066] For example, the cleaning tool A has been described as having an adhesive roll R attached to its tip, but the cleaning tool A is not limited to this type, and can be configured as various cleaning tools such as a mop, broom, wiper, etc.

[0067] In addition, the hanging handle connecting joint 42 has been described as connecting the tubular gripping portion 2 provided at the tip side to the hanging handle main body portion 41 provided at the base end side, but it may also be configured to connect a solid gripping portion 2 provided at the tip side to a tubular hanging handle main body portion 41.

[0068] Furthermore, the cleaning tool joint 3 has been described as connecting the rod-shaped tip extension portion 12 provided on the tip side and the grip portion 2 as a tubular body provided on the base end side, but is not limited to this configuration and may be configured to connect a tubular body provided on the tip side to a rod-shaped body provided on the base end side, or may be configured to connect a tubular body provided on the tip side to a tubular body provided on the base end side.

[0069] In addition, the tip extension portion 12 has been described as being inserted into the insertion port 3a and connected to the cleaning tool joint 3, but this is not limited to the above configuration and may be configured to be connected by adhesion or engagement, or the tip extension portion 12 and the cleaning tool joint 3 may be configured as a single unit by insert molding, etc.

[0070] Furthermore, although the protrusion 312 has been described as extending in a spiral shape on the outer circumferential surface of the base 311, the protrusion 312 may be configured as a protrusion of various shapes without being limited to this configuration. For example, the protrusion 312 may be configured as a protrusion extending along the axis, or as a plurality of protrusions extending in a direction intersecting both the axial direction and the circumferential direction. In addition, when the protrusion 312 is configured as a point-like protrusion, it may be configured to have three or more protrusions including two points spaced apart in the axial direction of the main body 31 and two points spaced apart in the circumferential direction of the main body 31. In addition, when the protrusion 312 is a point-like protrusion, it may be configured to have two protrusions spaced apart in the axial direction.

[0071] Further, the case where the tube end abutment portion 32 protruding radially outward from the tip end of the base portion 311 is provided has been described, but the present invention is not limited to this configuration, and the tube end abutment portion 32 may not be provided.

[0072] Furthermore, the case where the main body 31 is prevented from falling off the grip portion 2 by the pin P2 has been described, but the present invention is not limited to this configuration, and the main body 31 may be configured so that the pin P2 is not inserted.

[0073] Furthermore, the cleaning tool joint 3 is not limited to the shape shown in the drawings, and the dimensions and the number of turns of the protrusion 312 can be changed as desired. The shape of the tip (deformed portion 3122) of the protrusion 312 and the shapes of the tip and base ends of the cleaning tool joint 3 can be changed as desired.

[0074] Furthermore, although the protrusion 312 has been described as being configured such that the deformation portion 3122 deforms, it may be configured such that the base portion 3121 deforms, or such that both the deformation portion 3122 and the base portion 3121 deform.

[0075] In addition, although the case where the outer peripheral surface of base portion 3121 is a flat surface has been described, this is not limiting, and the outer surface of base portion 3121 may be curved, with deformation portion 3122 protruding from the curved surface.

[0076] Furthermore, the base portion 3121 and the deformation portion 3122 are described as being integrally molded, but the present invention is not limited to this configuration, and they may be molded in two colors.

[0077] In addition, although the hanging handle 4 has been described as having a hanging hole 4a, the present invention is not limited to this configuration. For example, the hanging handle 4 may be configured so that no hole is formed, and the hanging handle 4 is suspended by adhesion to a magnet provided on a wall or by a concave-convex fit.

[0078] Next, a cleaning tool joint 5 according to a second embodiment of the present invention will be described with reference to Figures 14 to 24. The same components as those in the first embodiment are given the same reference numerals and the description thereof will be omitted.

[0079] The cleaning tool joint 5 of this embodiment connects a tip pipe 6 provided on the tip side and a base pipe 7 provided on the base side. Specifically, the cleaning tool joint 5 includes a tip main body 51 inserted into the tip pipe 6, a base main body 52 inserted into the base pipe 7, and a connecting part 53 connecting the tip main body 51 and the base main body 52. ​​The connecting part 53 of this embodiment is configured to be able to abut against the end face of the tip pipe 6 and the end face of the base pipe 7. In addition, the cleaning tool joint 5 of this embodiment connects pipes having approximately the same inner diameter. Furthermore, the cleaning tool joint 5 of this embodiment connects the tip pipe 6 and the base pipe 7 in an undetachable manner.

[0080] In the cleaning tool joint 5 of this embodiment, the distal end body portion 51 and the proximal end body portion 52 have the same configuration and are provided on the connecting portion 53 so as to be symmetrical in the axial direction. Therefore, in this embodiment, the configuration of the distal end body portion 51 will be described, and a detailed description of the proximal end body portion 52 will be omitted.

[0081] The tip main body 51 comprises a tip base 511 whose outer diameter is smaller than the inner diameter of the tip tube 6, and a tip protrusion 512 that protrudes radially outward from the outer circumferential surface of the tip base 511. The outer diameter of the portion of the tip main body 51 where the tip protrusion 512 is provided is larger than the inner diameter of the base end of the tip tube 6. Furthermore, the tip main body 51 comprises a tip pin insertion section 513 at its tip, in which a tip pin insertion hole 513a, which is a hole through which pin P2 (see FIG. 23) can be inserted, is formed.

[0082] The tip base 511 is a rod-shaped body extending in the axial direction. The tip base 511 is a rod-shaped body having an inner diameter smaller than the base end of the tip tube 6. In this embodiment, the tip base 511 is a rod-shaped body extending from the tip pin insertion portion 513 to the connecting portion 53. Furthermore, the tip base 511 is a columnar body with a substantially constant outer diameter from the tip to the base end.

[0083] The tip protrusion 512 is a protrusion that protrudes radially outward from the outer circumferential surface of the tip base 511. The tip protrusion 512 is deformable by contacting with the inner circumferential surface of the base end of the tip tube 6. Specifically, the tip protrusion 512 includes a tip base 5121 that protrudes radially outward from the outer circumferential surface of the tip base 511, and a tip deformation portion 5122 that protrudes radially outward from the outer circumferential surface of the tip base 5121, and the tip deformation portion 5122 is deformable by contacting with the inner circumferential surface of the tip of the tip tube 6. The tip protrusion 512 of this embodiment is a protrusion that extends in a direction that intersects with both the axial direction and the circumferential direction of the tip base 511. The tip protrusion 512 is a protrusion that is provided to extend approximately around the entire circumference of the tip main body 51 in the circumferential direction. In this embodiment, tip protrusion 512 has a region 512a in which no protrusion (tip deformed portion 5122) is formed in the axial direction in order to be removed from the mold, and in this embodiment, the outer diameter of region 512a is smaller than the inner diameter of tip tube 6 (see FIG. 15). Furthermore, tip protrusion 512 is a protrusion provided in a spiral shape on the outer circumferential surface of tip base 511. That is, tip protrusion 512 is a protrusion provided on the outer circumferential surface of tip base 511 so as to extend over multiple revolutions in a direction intersecting both the axial and circumferential directions.

[0084] 22, tip base portion 5121 is connected to the outer circumferential surface of tip base portion 511 and extends radially outward from the outer circumferential surface of tip base portion 511. Tip base portion 5121 also includes tip base flat portion 5121a on its outer circumferential surface, which extends substantially parallel to the axis. Tip base flat portion 5121a is a flat surface having a certain width in the axial direction. Tip base flat portion 5121a is provided over the entire outer circumferential surface of tip base portion 5121.

[0085] The tip deformed portion 5122 is a portion that protrudes radially outward from the tip base portion 5121. The tip deformed portion 5122 is provided so as to protrude radially outward from the tip base flat portion 5121a. Furthermore, the tip deformed portion 5122 has a shape in which the tip portion (the end portion on the radially outer side) is thinner (has a shorter axial length) than the base portion (the connection portion 53 with the tip base flat portion 5121a). The tip portion of the tip deformed portion 5122 of this embodiment has an arc shape. Furthermore, the tip deformed portion 5122 of this embodiment is more easily deformed than the base portion of the tip tube 6. Furthermore, the tip deformed portion 5122 is relatively softer than the tip tube 6, and is therefore more easily deformed. Specifically, the tip portion of the tip deformed portion 5122 in the radial direction can be deformed so as to come into contact with the inner peripheral surface of the tip tube 6 and be crushed toward the base end side (diametrically inward).

[0086] The proximal main body 52 includes a proximal base 521 having an outer diameter smaller than the inner diameter of the proximal tubular body 7, and a proximal protrusion 522 protruding radially outward from the outer circumferential surface of the proximal base 521. The outer diameter of the portion of the proximal main body 52 where the proximal protrusion 522 is provided is larger than the inner diameter of the tip of the proximal tubular body 7. The proximal main body 52 further includes a proximal pin insertion portion 523 at its proximal end, in which a proximal pin insertion hole 523a, which is a hole through which the pin P2 (see FIG. 23) can be inserted, is formed.

[0087] As shown in Figs. 15 and 16, the base end protrusion 522 includes a base end base portion 5221 protruding radially outward from the base end base portion 521, and a base end deformation portion 5222 protruding radially outward from the base end base portion 5221. The configuration of the base end base portion 5221 is the same as the configuration of the tip base portion 5121, and the configuration of the base end deformation portion 5222 is the same as the configuration of the tip deformation portion 5122. That is, the base end deformation portion 5222 abuts against the inner peripheral surface of the base end tube 7 and deforms so as to be crushed radially inward. In addition, in the base end protrusion 522 of this embodiment, a region 522a in which no protrusion (base end deformation portion 5222) is formed along the axial direction is formed in a part of the circumferential direction in order to remove the base end protrusion 522 from the mold, and in this embodiment, the outer diameter of the region 522a is smaller than the inner diameter of the base end tube 7.

[0088] According to the cleaning tool joint 5 configured as described above, the tip body portion 51 is in close contact with the inner surface of the tube (tip tube 6) provided on the tip side, and the base body portion 52 is in close contact with the inner surface of the tube (base tube 7) provided on the base end, at at least two points spaced apart in a direction including the axial component, thereby preventing the tube provided on the tip side from wobbling relative to the tube provided on the base end.

[0089] Furthermore, since the tip protrusion 512 and the base end protrusion 522 extend in a direction intersecting both the axial direction and the circumferential direction, they can be more easily inserted into the tube provided on the tip side (tip tube 6) and the tube provided on the base side (base tube 7) than if the tip protrusion 512 and the base end protrusion 522 extended in the circumferential direction.

[0090] Furthermore, since the tip main body portion 51 is in close contact with the inner surface of the tip tube 6 around approximately the entire circumference, and the base main body portion 52 is in close contact with the inner surface of the base tube 7 around approximately the entire circumference, the adhesion force is less likely to vary in the circumferential direction, thereby preventing the tip tube 6 and the base tube 7 from wobbling.

[0091] Furthermore, since the tip protrusion 512 and the base end protrusion 522 are spirally shaped, it is easy to insert the tip main body 51 into the tip tube 6 and the base main body 52 into the base tube 7, and they can reliably abut against the inner surfaces of the tip tube 6 and the base tube 7.

[0092] Furthermore, when the tip body portion 51 and the base body portion 52 are removed from the mold and molded, there is an area 512a in which the tip protrusion 512 is not provided along the axial direction of the tip body portion 51, and an area 522a in which the base body portion 522 is not provided along the axial direction of the base body portion 52, making it easier to remove the tip body portion 51 and the base body portion 52 from the mold.

[0093] In addition, since the tip body portion 51 and the base body portion 52 are arranged axially symmetrically via the connecting portion 53, the cleaning tool joint 5 can be used even if the axial direction is reversed, thereby improving workability.

[0094] In the above embodiment, the distal end body portion 51 and the proximal end body portion 52 are described as being axially symmetrical with respect to the connecting portion 53, but the present invention is not limited to such a configuration and may be configured asymmetrically. For example, the outer diameters and axial lengths of the distal end body portion 51 and the proximal end body portion 52 can be changed in accordance with the distal end tubular body 6 and the proximal end tubular body 7.

[0095] Further, although the distal end main body portion 51 and the proximal end main body portion 52 are illustrated with holes penetrating in the axial direction, the present invention is not limited to this configuration, and may be such that no holes are formed.

[0096] Furthermore, the cleaning tool joint 5 is not limited to the shape shown in the drawings, and the dimensions, the number of turns of the protrusions (the distal protrusion 512 and the proximal protrusion 522), etc. can be changed as desired. The shape of the radial tip portions of the protrusions (the distal protrusion 512 and the proximal protrusion 522) and the shapes of the distal and proximal ends of the cleaning tool joint 5 can be changed as desired.

[0097] Next, a cleaning tool joint 5 according to a third embodiment of the present invention will be described with reference to Figures 25 to 35. The same components as those in the second embodiment are given the same reference numerals, and the description thereof will be omitted.

[0098] The cleaning tool joint 5 of this embodiment connects a distal end pipe 6 provided on the distal end side and a proximal end pipe 7 provided on the proximal end side. Specifically, the cleaning tool joint 5 includes a distal end main body portion 51 inserted into the distal end pipe 6, a proximal end main body portion 52 inserted into the proximal end pipe 7, and a connecting portion 53 connecting the distal end main body portion 51 and the proximal end main body portion 52. The connecting portion 53 of this embodiment is configured to be able to abut against the end faces of the distal end pipe 6 and the proximal end pipe 7.

[0099] The cleaning tool joint 5 of this embodiment differs from the second embodiment in the configuration of the distal end body portion 51 and the proximal end body portion 52. In this embodiment, the distal end body portion 51 and the proximal end body portion 52 have the same configuration and are provided on the connecting portion 53 so as to be symmetrical in the axial direction. Therefore, in this embodiment, the configuration of the distal end body portion 51 will be described, and a detailed description of the proximal end body portion 52 will be omitted. In addition, the cleaning tool joint 5 of this embodiment connects tubes having approximately the same inner diameter.

[0100] The tip main body 51 comprises a tip base 511 whose outer diameter is smaller than the inner diameter of the tip tube 6, and a tip deformed portion 5122 that protrudes radially outward from the outer circumferential surface of the tip base 511. That is, the tip main body 51 of this embodiment does not comprise a tip base portion. Also, the outer diameter of the portion of the tip main body 51 where the tip deformed portion 5122 is provided is larger than the inner diameter of the base end portion of the tip tube 6. Furthermore, the tip main body 51 comprises a tip pin insertion portion 513 at its tip portion, in which a tip pin insertion hole 513a, which is a hole through which the pin P2 (see FIG. 34) can be inserted, is formed.

[0101] The tip base 511 is a rod-shaped body extending in the axial direction. The tip base 511 is a rod-shaped body having an inner diameter smaller than the base end of the tip tube 6. In this embodiment, the tip base 511 is a rod-shaped body extending from the tip pin insertion portion 513 to the connecting portion 53. The tip base 511 is a cylinder having a substantially constant outer diameter from the tip to the base. The tip base 511 has a hole formed therein that penetrates radially from the tip to the base in the axial direction.

[0102] The distal end deformed portion 5122 is a portion where the distal end portion on the radially outer side abuts against the inner peripheral surface of the distal end tube 6 and deforms radially inward. The distal end deformed portion 5122 is a portion where the base end (the radially inner end) is connected to the outer peripheral surface of the distal end base 511 and protrudes radially outward from the outer peripheral surface of the distal end base 511. Furthermore, the distal end (the radially outer end) of the distal end deformed portion 5122 is thinner (has a shorter axial length) than the base end (the connecting portion 53 with the distal end base 511). The distal end deformed portion 5122 of this embodiment has a semicircular tip. The distal end deformed portion 5122 of this embodiment is more easily deformed than the base end of the distal end tube 6. Specifically, the distal end deformed portion 5122 can be deformed such that the radial tip abuts against the inner peripheral surface of the distal end tube 6 and is crushed toward the base end side (diametrically inward).

[0103] The base end main body portion 52 includes a base end base portion 521 and a base end deformation portion 5222. The configuration of the base end base portion 521 is similar to the configuration of the tip end base portion 511, and the configuration of the base end deformation portion 5222 is similar to the configuration of the tip end deformation portion 5122. The base end main body portion 52 also includes, at its base end, a base end pin insertion portion 523 having a base end pin insertion hole 523a formed therein, which is a hole through which the pin P2 (see FIG. 34) can be inserted.

[0104] According to the cleaning tool joint 5 configured as described above, the deformed portions (tip deformed portion 5122 and base deformed portion 5222) protrude from the base portion (tip base portion 511 and base base portion 521). Therefore, compared to the case where a base portion is provided, the deformed portions are less likely to fall in the axial direction, and the deformed portions can be reliably abutted against the pipe body.

[0105] The cleaning tool joint 5 is not limited to the shape shown in the drawings, and the dimensions, the number of turns of the protrusions (the distal deformed portion 5122 and the proximal deformed portion 5222), etc. can be changed as desired. The shape of the radial tip portion of the protrusions (the distal deformed portion 5122 and the proximal deformed portion 5222) and the shapes of the distal and proximal ends of the cleaning tool joint 5 can be changed as desired.
