Further, the head portion 11 has a cylindrical shape or a columnar shape, and is rotatably connected to the tip extending portion 12. The tip extending portion 12 is a rod-shaped portion formed by bending according to the shape of the head portion 11 so as to support the head portion 11 in the radial center. Specifically, the tip extending portion 12 is a rod-shaped portion whose outer diameter of the base end portion is smaller than the inner diameter of the grip portion 2, and further, the tip extending portion 12 has an outer diameter of the proximal end portion. It is a rod-shaped portion larger than the inner diameter of the insertion port 3a formed in the cleaning tool joint 3 described later.

The grip portion 2 is a columnar portion in which at least the tip end portion and the base end portion are formed hollow. The grip portion 2 of the present embodiment is formed to be hollow from the tip portion to the base end portion. Further, the grip portion 2 is a cylindrical body having a circular inside. In other words, the grip portion 2 of the present embodiment is a single tube. Further, the grip portion 2 of the present embodiment is made of metal.

As shown in FIG. 2, the hanging hand portion 4 is a portion that is inserted into a hook or the like and supports the entire cleaning tool A. As shown in FIG. 2, the hanging strap portion 4 includes a hanging strap main body 41 having a hanging hole 4a through which a hook or the like can be inserted, and a hanging strap connecting joint portion provided on the base end side of the hanging strap main body 41. 42 and. In such a hanging strap portion 4, the hanging strap connecting joint portion 42 is inserted into the base end portion of the gripping portion 2 and is connected to the gripping portion 2.

Considering that the hanging strap connecting joint portion 42 is a separate portion from the hanging strap main body portion 41, the hanging strap connecting joint portion 42 connects the gripping portion 2 as a pipe body provided on the tip side and the hanging strap main body portion 41. And fix it. Specifically, the tip side of the hanging strap connecting joint portion 42 is inserted into the grip portion 2, and the hanging strap main body portion 41 is joined to the proximal end portion of the hanging strap connecting joint portion 42 on the proximal end side. Further, the hanging strap connecting joint portion 42 has a hanging strap connecting base portion 421 having an outer diameter smaller than the inner diameter of the base end portion of the gripping portion 2, and a hanging strap connecting protrusion protruding outward from the outer peripheral surface of the hanging strap connecting base portion 421. A unit 422 and the like are provided. Further, the hanging strap connecting joint portion 42 has an outer diameter larger than the inner diameter of the base end portion of the gripping portion 2 at at least two points separated in the direction including the axial component of the portion including the hanging strap connecting protrusion 422. Further, the hanging strap connecting protrusion 422 is in contact with the inner peripheral surface of the base end portion of the grip portion 2 and can be deformed. Further, the hanging strap connecting joint portion 42 is formed with a hanging strap pin insertion hole 42a, which is a hole penetrating in the radial direction. Further, the hanging hand portion 4 of the present embodiment is made of resin. The outer diameter of the portion including the hanging strap connecting protrusion 422 is the outer diameter of the hanging strap connecting protrusion 422.

Specifically, the hanging strap connecting protrusion 422 is provided on the outer peripheral surface of the hanging strap connecting base 421 so as to extend in a direction intersecting both the axial direction and the circumferential direction. Further, the hanging strap connecting protrusion 422 is a protrusion provided over most of the entire circumference of the outer peripheral surface of the hanging strap connecting base portion 421. In the hanging strap connecting joint portion 42 of the present embodiment, a region in which no protrusion is formed in the axial direction is formed in a part in the circumferential direction. That is, in the hanging strap connecting base 42, a region in which no protrusion is formed is formed in a part in the circumferential direction, and the region extends along the axial direction. Therefore, the hanging strap connecting joint portion 42 can be easily removed from the mold. Further, the hanging strap connecting protrusion 422 is a protrusion provided in a spiral shape on the outer peripheral surface of the hanging strap connecting base portion 421.

Such a hanging strap portion 4 is connected to the gripping portion 2 by inserting the hanging strap connecting joint portion 42 into the gripping portion 2. Specifically, the hanging strap connecting joint portion 42 is inserted by rotating so as to be screwed into the base end portion of the grip portion 2. Further, the hanging strap connecting joint portion 42 is deformed so that the hanging strap connecting protrusion 422 abuts on the inner peripheral surface of the gripping portion 2 and has a reduced diameter as it is inserted into the gripping portion 2. Due to this deformation, a restoring force is generated on the hanging strap connecting protrusion 422 to the outside of the diameter. Therefore, since the hanging strap connecting protrusion 422 is in close contact with the inner peripheral surface of the gripping portion 2, the hanging strap portion 4 is attached to the gripping portion 2 in a state of being less likely to wobble. Further, after inserting the hanging strap connecting joint portion 42 into the gripping portion 2, the hanging strap is provided by providing the pin P1 so as to penetrate the gripping portion 2 in the radial direction and insert the hanging strap pin insertion hole 42a. It is possible to prevent the portion 4 from falling out of the grip portion 2.

As shown in FIGS. 3 to 11, the cleaning tool joint 3 connects the cleaning tip portion 1 and the grip portion 2. That is, the cleaning tip portion 1 is connected to the cleaning tool joint 3, and the grip portion 2 is connected to the proximal end side, whereby the cleaning tip portion 1 and the grip portion 2 are connected. Specifically, the cleaning tool joint 3 includes a main body portion 31 inserted into the tip end portion of the grip portion 2 which is a pipe body, and a pipe end contact portion 32 connected to the tip end portion of the main body portion 31. .. Further, the cleaning tool joint 3 is formed with an insertion port 3a into which the base end portion of the tip extension portion 12 can be inserted from the tip end portion of the main body portion 31 toward the proximal end side. The insertion port 3a of the present embodiment is a hole penetrating in the axial direction. Further, the inner diameter of the insertion port 3a is smaller than the outer diameter of the base end portion of the tip extending portion 12. Further, the cleaning tool joint 3 connects the cleaning tip portion 1 and the grip portion 2 in a detachable manner. That is, under normal use conditions, the connection between the cleaning tip portion 1 and the grip portion 2 is not released.

The cleaning tip portion 1 is connected to the cleaning tool joint 3 by inserting the tip extending portion 12 into the insertion port 3a. Specifically, the outer diameter of the tip portion of the tip extending portion 12 is larger than the inner diameter of the insertion port 3a. Therefore, when the tip extension portion 12 is inserted into the insertion port 3a, the tip extension portion 12 enters the base end side while expanding the inner wall of the insertion port 3a outward in diameter. Therefore, when the tip extension portion 12 is inserted into the insertion port 3a, the inner wall of the insertion port 3a comes into close contact with the tip extension portion 12. Therefore, the cleaning tip portion 1 is connected to the cleaning tool joint 3 in a state where wobbling is suppressed (see FIG. 12).

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

The base 311 is a rod-shaped body extending in the axial direction. Further, the base portion 311 is a rod-shaped body having an outer diameter smaller than the inner diameter of the tip portion of the grip portion 2. The base portion 311 of the present embodiment is a rod-shaped body extending from the pin insertion portion 313 to the pipe end contact portion 32. Further, the base portion 311 of the present embodiment is formed with a hole (insertion port 3a) penetrating in the axial direction from the tip end side to the base end side. Further, the base portion 311 is a columnar shape having a substantially constant outer diameter from the tip end portion to the base end portion.

The protrusion 312 is a protrusion that protrudes outward in diameter from the outer peripheral surface of the base 311. Further, the protrusion 312 abuts on the inner peripheral surface of the tip of the grip 2 and is deformable. Specifically, the protruding portion 312 includes a base portion 3121 provided so as to project outward in diameter from the outer peripheral surface of the base portion 311 and a deformed portion 3122 protruding outward in diameter from the outer peripheral surface of the base portion 3121. The deformable portion 3122 can be deformed by abutting on the inner peripheral surface of the tip end portion of the grip portion 2. The protrusion 312 of the present embodiment is a protrusion extending in a direction intersecting both the axial direction and the circumferential direction of the base portion 311. Further, the protrusion 312 is a protrusion provided so as to extend substantially around the circumference of the main body 31 in the circumferential direction. In the protrusion 312 of the present embodiment, a region 312a in which no protrusion (deformed portion 3122) is formed is formed in a part in the circumferential direction. That is, in the protrusion 312, a region in which the protrusion (deformed portion 3122) is not formed is formed in a part in the circumferential direction, and the region extends along the axial direction. In other words, the protrusion 312 is formed with a plurality of spiral protrusions (deformed portion 3122) extending less than one circumference in the circumferential direction. Further, in the present embodiment, the outer diameter of the region 312a is smaller than the inner diameter of the grip portion 2 (see FIG. 4). Therefore, the protrusion 312 can be easily removed from the mold. Further, the protrusion 312 is a protrusion spirally provided on the outer peripheral surface of the base 311. That is, the protrusion 312 is a protrusion provided on the outer peripheral surface of the base 311 so as to extend over a plurality of circumferences in a direction intersecting both the axial direction and the circumferential direction. Further, the base portion 3121 and the deformed portion 3122 of the present embodiment are integrally molded.

As shown in FIG. 11, the base portion 3121 is connected to the outer peripheral surface of the base portion 311 and extends outward in diameter from the outer peripheral surface of the base portion 311. Further, the base portion 3121 is provided with a base flat portion 3121a extending substantially parallel to the axis on the outer peripheral surface. Further, the base plane portion 3121a is a plane having a constant width in the axial direction. Further, the base flat surface portion 3121a is provided over the entire outer peripheral surface of the base portion 3121.

The deformed portion 3122 is a portion that protrudes outward in diameter from the base portion 3121. Further, the deformed portion 3122 is provided so as to project outward in diameter from the base flat surface portion 3121a. Further, the deformed portion 3122 has a shape in which the tip portion (end outside the diameter) is thinner than the base end portion (connecting portion with the base flat surface portion 3121a) (the length in the axial direction is short). The deformed portion 3122 of the present embodiment has an arcuate tip portion. Further, since the deformed portion 3122 of the present embodiment is relatively softer than the tip portion of the grip portion 2, it is easily deformed. Specifically, the deformed portion 3122 can be deformed so that the tip portion abuts on the inner peripheral surface of the grip portion 2 and is crushed toward the proximal end side. Due to this deformation, a restoring force to the outer diameter is generated in the deformed portion 3122.

The pipe end contact portion 32 is a portion capable of contacting the end surface of the grip portion 2 on the base end side. Specifically, the pipe end contact portion 32 is a portion whose outer diameter is larger than the inner diameter of the grip portion 2. Further, the pipe end contact portion 32 is a portion that protrudes outward in diameter from the outer peripheral surface of the tip portion of the base portion 311. In the present embodiment, the pipe end contact portion 32 is a protrusion protruding outward in diameter over one circumference in the circumferential direction of the base portion 311. Specifically, the pipe end contact portion 32 has an annular contact portion 321 protruding outward in diameter from the outer peripheral surface of the base portion 311 and a positioning portion 322 protruding from the annular contact portion 321 toward the base end side. And.

The annular contact portion 321 is an annular portion whose outer diameter is larger than the inner diameter of the base end portion. Further, the annular contact portion 321 has an end portion inside the diameter connected to the outer peripheral surface of the base portion 311. Further, the annular contact portion 321 is provided substantially coaxially with the base portion 311. Further, the outer diameter of the annulus 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.

The positioning portion 322 is a plurality of protrusions extending from the annular contact portion 321 toward the proximal end side. When the plurality of positioning portions 322 are inserted into the grip portion 2, they come into contact with the inner peripheral surface of the grip portion 2 and prevent the grip portion 2 from shifting with respect to the pipe end contact portion 32. Further, the positioning portion 322 extends from the annular contact portion 321 toward the proximal end side. Therefore, it is possible to reinforce the annular contact portion 321 and prevent the annular contact portion 321 from being deformed so as to enter the inside of the grip portion 2.

To the cleaning tool joint 3 having the above configuration, the tip extension portion 12 is connected to the tip side, and the grip portion 2 is connected to the base end side. Specifically, the tip extension portion 12 is connected to the tip portion of the cleaning tool joint 3 by inserting the tip extension portion 12 into the insertion port 3a. Further, the grip portion 2 is connected to the base end side of the cleaning tool joint 3 by inserting the grip portion 2.

As shown in FIG. 13, since the inner diameter of the insertion port 3a is smaller than the outer diameter of the tip extension portion 12, the inner wall of the insertion port 3a of the base portion 311 is in close contact with the outer peripheral surface of the inserted tip extension portion 12. .. Therefore, the cleaning tip portion 1 is connected to the cleaning tool joint 3 in a state where wobbling is suppressed.

Further, the main body portion 31 has a larger outer diameter than the inner diameter of the grip portion 2 at the portion where the protrusion 312 is provided. Therefore, the protrusion 312 comes into close contact with the inner peripheral surface of the grip 2. Specifically, the deformed portion 3122 is pushed inward by the inner peripheral surface of the gripped portion 2 and deformed. The outer peripheral surface of the deformed portion 3122 is deformed into a shape along the inner peripheral surface of the grip portion 2 and comes into close contact with the inner peripheral surface of the grip portion 2.

When the main body portion 31 is inserted into the grip portion 2, the 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 from the grip 2.

The configuration and operation related to the above embodiment are summarized below.

According to the cleaning tool joint 3 having the above configuration, when the main body portion 31 is inserted into the pipe body (grip portion 2), the protrusion portion 312 abuts on the inner peripheral surface of the pipe body and is deformed. can. Therefore, since the main body 31 is in close contact with the inner peripheral surface of the tubular body at at least two points separated in the direction including the axial component, it is difficult for the tubular body to float with respect to the inner peripheral surface of the tubular body. It can suppress wobbling.

Further, the protrusion 312 extends in a direction intersecting both the axial direction and the circumferential direction of the base 311. Therefore, as compared with the case where the protrusion 312 extends in the circumferential direction, the resistance received by the cleaning tool joint 3 at the time of insertion becomes smaller, and the main body 31 can be easily inserted into the pipe body (grip portion 2).

Further, the main body portion 31 is in close contact with the inner peripheral surface of the tubular body (grip portion 2) over substantially one circumference (specifically, a section provided with the deformed portion 3122). Therefore, since the force applied in the radial direction of the tubular body can be reliably received by the main body portion 31, it is possible to suppress the wobbling of the tubular body.

Also, the protrusion 312 is spiral. Therefore, when the main body portion 31 is inserted into the tube body (grip portion 2), it is easy to insert the main body portion 31, and the protrusion portion 312 can surely come into contact with the inner peripheral surface of the tube body.

Further, the base portion 311 is formed with a region 312a in which a protrusion (specifically, a deformed portion 3122) is not provided along the axial direction. Therefore, when the main body 31 is removed from the mold for molding, the main body 31 can be easily removed from the mold.

Further, the deformed portion 3122 provided at the tip portion of the protruding portion 312 is deformed. Therefore, the protrusion 312 can surely come into contact with the inner peripheral surface of the tubular body (grip portion 2).

Further, the protruding portion 312 includes a base portion 3121 provided so as to project outward in diameter from the outer peripheral surface of the base portion 311 and a deformed portion 3122 protruding outward in diameter from the outer peripheral surface of the base portion 3121. The width in the axial direction is smaller than the width in the axial direction of the outer peripheral surface of the base portion 3121. Therefore, the deformed portion 3122 can be deformed with less force than when the base portion 3121 is deformed. Therefore, it is easy to insert the main body portion 31 into the tubular body (grip portion 2).

Further, the shape of the tip portion outside the diameter of the protrusion 312 (the tip portion of the deformed portion 3122) is an arc shape. Therefore, it can surely come into contact with the inner peripheral surface of the tubular body (grip portion 2) and be deformed.

Further, the main body 31 has protrusions 312 on the front surface and the rear surface at least based on the movement direction at the time of cleaning (in this embodiment, the movement direction when the adhesive roll R is rotated around the axis of the head portion 11).
