[0008] Patent Document 1: Japanese Patent Application Publication No. 2016-32627 Summary of the Invention

[0009] The problem the invention aims to solve

[0010] In the adhesive tape cleaning tool described in Patent Document 1, the extension rod is connected to the support handle by inserting it into the extension rod hole and engaging it with a locking hook. However, due to manufacturing tolerances, a gap occurs between the inner circumferential surface of the extension rod hole and the outer circumferential surface of the extension rod in this connection method. Therefore, there is a problem of instability and wobbling of the extension rod relative to the support handle.

[0011] Therefore, the object of the present invention is to provide a connector for cleaning tools and a cleaning tool that can suppress the shaking of the part provided on the front end side relative to the part provided on the base end side.

[0012] Solution for solving the problem

[0013] The cleaning tool connector of the present invention is used in a cleaning tool to connect and fix a front end portion located at the front end side and a base end portion located at the base end side of the cleaning tool. At least one of the front end portion and the base end portion is a tube. The cleaning tool connector has a main body portion that is inserted into the interior of the tube. The main body portion has: a base portion whose outer diameter is smaller than the inner diameter of the tube; and a protrusion portion having at least one protrusion portion that protrudes radially outward from the outer peripheral surface of the base. The outer diameter of at least two points on the outer peripheral surface of the protrusion portion portion that are separated in a direction including the axial direction component of the base is larger than the inner diameter of the tube. The at least one protrusion portion is deformable by abutting against the inner peripheral surface of the tube.

[0014] Alternatively, the at least one protrusion may be configured such that it is composed of two or more protrusions, and the outer diameter of the at least two points on the outer peripheral surface of the protrusion location is the outer diameter of each of the two or more protrusions.

[0015] Alternatively, the protrusion can be configured to extend in a direction that intersects both the axial direction and the circumferential direction of the base.

[0016] Alternatively, the protrusion can be configured such that it extends within approximately one circumference of the main body.

[0017] In addition, the protrusion may be a spirally arranged protrusion on the outer peripheral surface of the base.

[0020] Furthermore, the cleaning tool connector of the present invention is used in cleaning tools for connecting and fixing a tube body provided on the front end side and a tube body provided on the base end side of the cleaning tool. The cleaning tool connector has: a front end main body portion inserted into the tube body provided on the front end side; and a base end main body portion inserted into the tube body provided on the base end side. The front end main body portion has: a front end base portion whose outer diameter is smaller than the inner diameter of the tube body provided on the front end side; and a front end protrusion portion having at least one front end protrusion portion protruding radially outward from the outer peripheral surface of the front end base portion. At least two protrusion portions are separated on the outer peripheral surface of the front end protrusion portion portion in a direction including the axial direction component of the front end base portion. The outer diameter of the point is larger than the inner diameter of the tube body located on the front end side. The at least one front end protrusion is deformable by abutting against the inner circumferential surface of the tube body located on the front end side. The base end main body has: a base end base whose outer diameter is smaller than the inner diameter of the tube body located on the base end side; a base end protrusion location having at least one base end protrusion protruding radially outward from the outer circumferential surface of the base end base. The outer diameters of at least two points on the outer circumferential surface of the base end protrusion location, separated in a direction including the axial direction component of the base end base, are larger than the inner diameter of the tube body located on the base end side. The at least one base end protrusion is deformable by abutting against the inner circumferential surface of the tube body located on the base end side.

[0021] Alternatively, the at least one front protrusion may be configured such that it is composed of two or more protrusions, and the outer diameter of at least two points on the outer peripheral surface of the front protrusion is the outer diameter of each of the two or more protrusions.

[0022] Alternatively, the at least one base protrusion may be configured such that it is composed of two or more protrusions, and the outer diameter of at least two points on the outer peripheral surface of the base protrusion location is the outer diameter of each of the two or more protrusions.

[0023] Alternatively, the front end protrusion can be configured to extend in a direction that intersects both the axial direction and the circumferential direction of the front end base, and the base end protrusion can be configured to extend in a direction that intersects both the axial direction and the circumferential direction of the base end base.

[0024] Alternatively, the front end protrusion can be configured such that it extends approximately within a circumference of the front end main body, and the base end protrusion extends approximately within a circumference of the base end main body.

[0025] Alternatively, the front end protrusion can be configured such that it is a spirally arranged protrusion on the outer peripheral surface of the front end base, and the base end protrusion is a spirally arranged protrusion on the outer peripheral surface of the base end base.

[0026] Alternatively, the front end main body may have a region in which the front end protrusion is not provided within the axial direction, and the base end main body may have a region in which the base end protrusion is not provided within the axial direction.

[0027] In addition, the cleaning tool of the present invention includes: a cleaning front end, provided on the front end side, having a cleaning main body part that cleans the object to be cleaned by contacting it; a gripping part, provided on the base end side, for being gripped during cleaning; and a cleaning tool connector as described in any one of the above technical solutions 1 to 5, which connects the cleaning front end and the gripping part.

[0063] Reference Figures 1 to 13 One embodiment of the present invention will be described. Furthermore, in the following description, the front end side and the base end side will be referred to as... Figure 1 The description of the cleaning tool A as a whole is based on its orientation (except for individual descriptions of each part). In addition, in the following description, separation in a direction that includes the axial direction component means separation in the axial direction. If it is separation in the axial direction, then its circumferential or radial position is irrelevant.

[0064] like Figure 1 As shown, the cleaning tool A includes: a cleaning front end 1 located at the front end, a gripping part 2 located at the base end, a cleaning tool connector 3 connecting the cleaning front end 1 and the gripping part 2, and a hanging part 4 connected to the base end of the gripping part 2. The cleaning front end 1 is configured as a cleaning main body capable of mounting an adhesive roller R or similar device to remove dirt or other contaminants through contact with the object being cleaned. The gripping part 2 is a portion for the user to hold during cleaning. Furthermore, this cleaning tool A maintains the connection between its various parts under normal use conditions. That is, the connection between the various parts of the cleaning tool A is not released under normal use conditions.

[0065] The cleaning front end portion 1 has: a head 11 for mounting the cleaning main body and a front extension portion 12 extending from the head 11 toward the base end. The head 11 is cylindrical or cylindrical and is connected to the front extension portion 12 in a rotatable manner. The front extension portion 12 is a rod-shaped portion formed by bending to match the shape of the head 11 in order to support the head 11 at its radial center. Specifically, the front extension portion 12 is a rod-shaped portion whose outer diameter at the base end is smaller than the inner diameter of the gripping portion 2, and the outer diameter at the base end is a rod-shaped portion whose inner diameter is larger than the inner diameter of the insertion port 3a of the cleaning tool connector 3 described later. Furthermore, the head 11 of the cleaning front end portion 1 in this embodiment is made of resin. The front extension portion 12 of the cleaning front end portion 1 is made of metal.

[0066] The grip portion 2 is a hollow, columnar portion, at least at its front and base ends. In this embodiment, the grip portion 2 is hollow from its front to its base end. Furthermore, the grip portion 2 is a cylindrical body with a circular interior. In other words, the grip portion 2 in this embodiment is a tube. Additionally, the grip portion 2 in this embodiment is made of metal.

[0067] like Figure 2 As shown, the hanging part 4 is for inserting hook components and other parts, and is used to support the entire cleaning tool A. Figure 2 As shown, the hanging part 4 includes: a hanging main body part 41 with a hanging hole 4a, and a hanging connecting joint part 42 provided at the front end of the hanging main body part 41, wherein the hanging hole 4a allows a hook component or the like to be inserted through. The hanging part 4, with its hanging connecting joint part 42 inserted into the base end of the gripping part 2, is thus connected to the gripping part 2.

[0068] If the suspension connector portion 42 and the suspension body portion 41 are considered as separate parts, the suspension connector portion 42 connects and fixes the grip portion 2, which is a tube body, located at the front end side to the suspension body portion 41. Specifically, the grip portion 2 is inserted into the front end side of the suspension connector portion 42, while the suspension body portion 41 is joined to the base end of the suspension connector portion 42 at its base end side. In addition, the suspension connector portion 42 has: a suspension base portion 421 with an outer diameter smaller than the inner diameter of the base end of the grip portion 2; and a suspension protrusion 422 protruding outward from the outer circumference of the suspension base portion 421. Moreover, at at least two points where the portion of the suspension connector portion 42 with the suspension protrusion 422 is separated in a direction including the axial direction, its outer diameter is larger than the inner diameter of the base end of the grip portion 2. Furthermore, the hanging connection protrusion 422 is deformable after abutting against the inner circumferential surface of the base end of the gripping part 2. Additionally, a radially penetrating hole, namely a hanging pin insertion hole 42a, is formed on the hanging connection joint part 42. Moreover, the hanging part 4 in this embodiment is made of resin. Furthermore, the outer diameter of the portion having the hanging connection protrusion 422 refers to the outer diameter of the hanging connection protrusion 422.

[0069] Specifically, the hanging connection protrusion 422 is provided on the outer peripheral surface of the hanging connection base 421 in a direction intersecting both the axial and circumferential directions. Furthermore, the hanging connection protrusion 422 is a protrusion covering a large portion of the entire circumference of the outer peripheral surface of the hanging connection base 421. Additionally, a region without a protrusion in the axial direction is formed on a portion of the circumferential direction of the hanging connection joint 42 in this embodiment. That is, a region without a protrusion is formed on a portion of the circumferential direction of the hanging connection base 421, and this region extends along the axial direction. Therefore, the hanging connection joint 42 is easily demolded from the mold. Moreover, the hanging connection protrusion 422 is a spirally provided protrusion on the outer peripheral surface of the hanging connection base 421.

[0070] The hanging part 4 is connected to the gripping part 2 by inserting the hanging connection joint 42 into the gripping part 2. Specifically, the hanging connection joint 42 is screwed into the base end of the gripping part 2 by rotation. Furthermore, as the hanging connection joint 42 is inserted into the gripping part 2, its hanging connection protrusion 422 abuts against the inner circumferential surface of the gripping part 2 and deforms by reducing its diameter. This deformation generates a radially outward restoring force on the hanging connection protrusion 422. Therefore, the hanging connection protrusion 422 is in close contact with the inner circumferential surface of the gripping part 2, thereby ensuring that the hanging part 4 is installed in a stable state without wobbling. Additionally, after the hanging connection joint 42 is inserted into the gripping part 2, a pin P1 is provided that penetrates the gripping part 2 radially and passes through the hanging pin insertion hole 42a, thereby preventing the hanging part 4 from being pulled out of the gripping part 2.

[0071] like Figures 3 to 11 As shown, the cleaning tool connector 3 connects the cleaning front end 1 and the gripping part 2. Specifically, the cleaning front end 1 is connected to the front end side of the cleaning tool connector 3, and the gripping part 2 is connected to the base end side, thereby connecting the cleaning front end 1 and the gripping part 2. Specifically, the cleaning tool connector 3 has: a main body 31 that is inserted into the tube body, i.e., the front end of the gripping part 2; and a tube end abutment 32 connected to the front end of the main body 31. Furthermore, an insertion port 3a is formed on the cleaning tool connector 3, allowing the base end of the front extension part 12 to be inserted from the front end of the main body 31 toward the base end side into the insertion port 3a. In this embodiment, the insertion port 3a is a through hole in the axial direction. Additionally, the inner diameter of the insertion port 3a is smaller than the outer diameter of the base end of the front extension part 12. Moreover, the cleaning tool connector 3 connects the cleaning front end 1 and the gripping part 2 in a non-detachable manner. That is, under normal use, the connection between the cleaning front end 1 and the grip part 2 cannot be disconnected.

[0072] The cleaning front end 1 is connected to the cleaning tool connector 3 by inserting the front extension portion 12 into the insertion port 3a. Specifically, the outer diameter of the front end of the front extension portion 12 is larger than the inner diameter of the insertion port 3a. Therefore, when the front extension portion 12 is inserted into the insertion port 3a, the front extension portion 12 widens the inner wall of the insertion port 3a to the base end side. Therefore, when the front extension portion 12 is inserted into the insertion port 3a, the inner wall of the insertion port 3a is in close contact with the front extension portion 12. Therefore, the cleaning front end 1 is connected to the cleaning tool connector 3 (see reference 3) in a state that suppresses wobbling. Figure 12 ).

[0073] The main body 31 has: a base 311 with an outer diameter smaller than the inner diameter of the front end of the gripping part 2; and a protrusion 312 protruding radially outward from the outer periphery of the base 311. Furthermore, in the main body 31, the outer diameter of the portion with the protrusion 312 is larger than the inner diameter of the front end of the gripping part 2. Moreover, the main body 31 has a pin insertion portion 313, which has a base end portion capable of receiving a pin P2 (see reference). Figure 12 The insertion hole is the connector pin insertion through hole 313a. In addition, the outer diameter of the part with the protrusion 312 refers to the outer diameter of the protrusion 312.

[0074] The base 311 is a rod-shaped body extending in the axial direction. Furthermore, the base 311 is a rod-shaped body with an outer diameter smaller than the inner diameter of the front end of the gripping part 2. In this embodiment, the base 311 is a rod-shaped body extending from the pin insertion part 313 to the tube end abutment part 32. Moreover, in this embodiment, a hole (insertion port 3a) is formed on the base 311, extending along the axial direction from the front end side to the base end side. Additionally, the base 311 is cylindrical with an outer diameter that is approximately the same from the front end to the base end.

[0075] The protrusion 312 is a protrusion that projects radially outward from the outer peripheral surface of the base 311. Furthermore, the protrusion 312 is deformable by abutting against the inner peripheral surface of the front end of the grip portion 2. Specifically, the protrusion 312 has a base portion 3121 that projects radially outward from the outer peripheral surface of the base 311, and a deformable portion 3122 that projects radially outward from the outer peripheral surface of the base portion 3121. The deformable portion 3122 is deformable by abutting against the inner peripheral surface of the front end of the grip portion 2. In this embodiment, the protrusion 312 extends in a direction intersecting both the axial and circumferential directions of the base 311. Furthermore, the protrusion 312 is a protrusion that extends approximately around the circumference of the main body portion 31. Additionally, in this embodiment, a region 312a is formed in the circumferential direction of the protrusion 312 where no protrusion (deformable portion 3122) is formed in the axial direction. That is, a region without protrusions (deformed portions 3122) is formed locally in the circumferential direction of the protrusion 312, and this region extends along the axial direction. In other words, the protrusion 312 has a plurality of spiral protrusions (deformed portions 3122) extending less than one revolution in the circumferential direction. In addition, in this embodiment, the outer diameter of this region 312a is smaller than the inner diameter of the gripping portion 2 (see reference). Figure 4 Therefore, the protrusion 312 is easily demolded from the mold. Furthermore, the protrusion 312 is a spiral protrusion 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 in a manner extending over several circumferences in directions intersecting both the axial and circumferential directions. Additionally, in this embodiment, the base portion 3121 and the deformable portion 3122 are integrally formed.

[0076] like Figure 11 As shown, the base portion 3121 is a portion connected to the outer peripheral surface of the base portion 311 and extending radially outward from the outer peripheral surface of the base portion 311. Furthermore, the base portion 3121 has a base plane portion 3121a extending substantially parallel to the axis on its outer peripheral surface. The base plane portion 3121a is a plane with a certain width in the axial direction. Moreover, the base plane portion 3121a is provided throughout the entire outer peripheral surface of the base portion 3121.

[0077] The deformable portion 3122 is a portion that protrudes radially outward from the base portion 3121. Furthermore, the deformable portion 3122 is provided such that it protrudes radially outward from the base plane portion 3121a. Moreover, the deformable portion 3122 has a shape where its front end (the radially outward end) is thinner (shorter in axial length) than its base end (the portion connecting to the base plane portion 3121a). In this embodiment, the front end of the deformable portion 3122 is arc-shaped. Additionally, the deformable portion 3122 in this embodiment is relatively softer than the front end of the grip portion 2, and therefore easily deformable. Specifically, the front end of the deformable portion 3122 abuts against the inner circumferential surface of the grip portion 2, thereby allowing it to deform by crushing towards its base end. This deformation generates a radially outward restoring force in the deformable portion 3122.

[0078] The tube end abutment portion 32 is a portion that can abut against the end face of the base end side of the grip portion 2. Specifically, the tube end abutment portion 32 is a portion whose outer diameter is larger than the inner diameter of the grip portion 2. In addition, the tube end abutment portion 32 is a portion that protrudes radially outward from the outer peripheral surface of the front end of the base portion 311. In this embodiment, the tube end abutment portion 32 is a protrusion that protrudes radially outward within a circumferential range of the base portion 311. Specifically, the tube end abutment portion 32 has: an annular abutment portion 321 that protrudes radially outward from the outer peripheral surface of the base portion 311, and a positioning portion 322 that protrudes radially outward from the annular abutment portion 321 towards the base end side.

[0079] The annular abutment portion 321 is an annular portion with an outer diameter larger than the inner diameter of the base end. Furthermore, the inner end of the annular abutment portion 321 is connected to the outer peripheral surface of the base 311. Moreover, the annular abutment portion 321 and the base 311 are provided approximately coaxially. Additionally, the outer diameter of the annular abutment portion 321 is approximately equal to the outer diameter of the grip portion 2. This annular abutment portion 321 can close the front end of the grip portion 2.

[0080] The positioning portions 322 are multiple protrusions extending from the annular abutment portion 321 toward the base end. When the gripping portion 2 is inserted, the multiple positioning portions 322 abut against the inner circumferential surface of the gripping portion 2, preventing the gripping portion 2 from shifting relative to the tube end abutment portion 32. Furthermore, the positioning portions 322 extend from the annular abutment portion 321 toward the base end. Therefore, the annular abutment portion 321 can be reinforced, and deformation of the annular abutment portion 321 that would otherwise penetrate into the gripping portion 2 can be prevented.

[0081] In the cleaning tool connector 3 configured as described above, a front extension portion 12 is connected to its front end side, and a grip portion 2 is connected to its base end side. Specifically, the front extension portion 12 is connected to the front end of the cleaning tool connector 3 by inserting it into the insertion port 3a. Furthermore, the grip portion 2 is connected to the base end side of the cleaning tool connector 3 by inserting it into the base end side.

[0082] like Figure 13 As shown, since the inner diameter of the insertion port 3a is smaller than the outer diameter of the front extension portion 12, the inner wall of the insertion port 3a of the base 311 will fit tightly against the outer peripheral surface of the inserted front extension portion 12. Therefore, the cleaning front end 1 can be connected to the cleaning tool connector 3 in a state that suppresses shaking.

[0083] Furthermore, in the portion of the main body 31 with the protrusion 312, the outer diameter is larger than the inner diameter of the grip portion 2. Therefore, the protrusion 312 fits tightly against the inner circumferential surface of the grip portion 2. Specifically, the deformable portion 3122 is compressed by the inner circumferential surface of the grip portion 2 and deforms radially inward. The outer circumferential surface of the deformable portion 3122 deforms into a shape that follows the inner circumferential surface of the grip portion 2 and fits tightly against the inner circumferential surface of the grip portion 2.

[0084] After the main body 31 is inserted into the gripping part 2, the pin P2 is inserted through the gripping part 2 and the pin insertion part 313. The pin P2 can prevent the main body 31 from falling off the gripping part 2.

[0085] The structure and function of the aforementioned implementation method are summarized and recorded as follows.

[0086] With the cleaning tool connector 3 configured as described above, when the main body 31 is inserted into the tube body (holding part 2), the protrusion 312 will abut against the inner circumferential surface of the tube body and deform. As a result, the main body 31 is in close contact with the inner circumferential surface of the tube body at at least two points that are separated in the direction including the axial direction, so it is difficult to create points that are loose relative to the inner circumferential surface of the tube body, and the tube body can be suppressed from shaking and instability.

[0087] Furthermore, the protrusion 312 extends in a direction that intersects both the axial direction and the circumferential direction of the base 311. Therefore, compared to the case where the protrusion 312 extends circumferentially, the resistance encountered by the cleaning tool connector 3 during insertion is reduced, making it easier to insert the main body 31 into the tube body (holding part 2).

[0088] Furthermore, the main body 31 fits tightly around approximately one circumference of the inner circumference of the tube body (grip 2) (specifically, the area with the deformable portion 3122). Therefore, the main body 31 can reliably withstand the radial force applied to the tube body, thus suppressing tube body swaying and instability.

[0089] Furthermore, the protrusion 312 is spiral-shaped. Therefore, it is easy to insert the main body 31 into the tube (holding part 2), and the protrusion 312 can reliably abut against the inner circumferential surface of the tube.

[0090] Furthermore, a region 312a is formed in the base 311 where no protrusion (specifically, a deformable portion 3122) is provided in the axial direction. Therefore, when the main body 31 is demolded from the mold and formed, the main body 31 can be easily demolded from the mold.

[0091] Furthermore, the deformable portion 3122 located at the front end of the protrusion 312 will deform. Therefore, the protrusion 312 can reliably abut against the inner circumferential surface of the tube body (grip 2).

[0092] Furthermore, the protrusion 312 has a base portion 3121 that protrudes radially outward from the outer peripheral surface of the base portion 311, and a deformable portion 3122 that protrudes radially outward from the outer peripheral surface of the base portion 3121. The width of the deformable portion 3122 in the axial direction is smaller than the width of the outer peripheral surface of the base portion 3121 in the axial direction. Therefore, the deformable portion 3122 can be deformed with a smaller force than that required to deform the base portion 3121. Therefore, the main body portion 31 can be easily inserted into the tube body (holding portion 2).

[0093] Furthermore, the outermost front end of the protrusion 312 (the front end of the deformable part 3122) is arc-shaped. Therefore, the protrusion can reliably abut against and deform against the inner circumferential surface of the tube body (grip 2).

[0094] Furthermore, protrusions 312 are formed on the main body 31, at least on the front and rear sides, based on the direction of movement during cleaning (in this embodiment, the direction of movement when the adhesive roller R rotates around the axis center of the head 11). Therefore, during cleaning, even if a load is applied to the head 11, the gripping part 2 is unlikely to wobble relative to the cleaning front end 1.

[0095] Furthermore, by constructing the cleaning tool A as described above, a cleaning tool A can be obtained that can suppress the shaking of the part provided on the front end side relative to the part provided on the base end side.

[0096] The cleaning tool A and the cleaning tool connector 3 of the present invention have been described above by way of example. However, the present invention is not limited to the described embodiments, and various modifications can be made without departing from the spirit of the present invention. In addition, the cleaning tool A and the cleaning tool connector 3 of the present invention are not limited to the effects described above.

[0097] For example, the invention has been described with an adhesive roller R installed at the front end of the cleaning tool A. However, the invention is not limited to such a cleaning tool A. For example, it can also be configured as various cleaning tools such as mops, brooms, and squeegees.

[0098] Furthermore, the case where the hanging connection joint 42 connects the gripping part 2 of the tube body located at the front end and the hanging main body 41 located at the base end has been described. However, the present invention is not limited to this structure. For example, it is also possible to configure it so that the solid gripping part 2 located at the front end is connected to the tubular hanging main body 41.

[0099] Furthermore, the invention describes a configuration where the cleaning utensil connector 3 connects the rod-shaped front extension 12 on the front end side to the gripping portion 2, which serves as the tube body, on the base end side. However, the invention is not limited to this structure. For example, it can also be configured to connect the tube body on the front end side to the rod-shaped body on the base end side. Additionally, it can also be configured to connect the tube body on the front end side to the tube body on the base end side.

[0100] Furthermore, the case where the front extension portion 12 is inserted into the insertion port 3a to connect it to the cleaning utensil connector 3 has been described. However, the present invention is not limited to this structure. For example, it can also be configured to be connected by adhesive or snap-fit. In addition, the front extension portion 12 and the cleaning utensil connector 3 can also be integrally formed by embedding molding or the like.

[0101] Furthermore, the case where the protrusion 312 extends spirally on the outer peripheral surface of the base 311 has been described. However, the protrusion 312 is not limited to this structure and can be configured as protrusions of various shapes. For example, it can also be configured as a protrusion extending along the axis. It can also be configured as multiple protrusions extending in directions intersecting both the axial and circumferential directions. In addition, when the protrusion 312 is configured as a point-like protrusion, it can also be configured to have three or more protrusions, including two points separated in the axial direction of the main body 31 and two points separated in the circumferential direction of the main body 31. Moreover, when the protrusion 312 is configured as a point-like protrusion, it can also be configured to have two point protrusions separated in the direction along the axial direction.

[0102] Furthermore, the case where a tube end abutment portion 32 protrudes radially outward from the front end of the base 311 has been described. However, the present invention is not limited to this structure. For example, it is also possible to configure the invention without the tube end abutment portion 32.

[0103] Furthermore, it was explained that the pin P2 is used to prevent the main body 31 from falling off the gripping part 2. However, the main body 31 is not limited to this structure. For example, it can also be configured so that the pin P2 is not inserted.

[0104] Furthermore, the cleaning tool connector 3 is not limited to the shape shown in the figure. For example, the size, the number of turns of the protrusion 312, etc., can be changed arbitrarily. The shape of the front end (deformation part 3122) of the protrusion 312, the shape of the front end and the base end of the cleaning tool connector 3 can be changed arbitrarily.

[0105] Furthermore, the deformation of the deformable portion 3122 of the protrusion 312 has been described. However, the present invention is not limited to this structure. For example, it is also possible to configure the base portion 3121 to be deformed. It is also possible to configure both the deformable portion 3122 and the base portion 3121 to be deformed.

[0106] Furthermore, the case where the outer peripheral surface of the base portion 3121 is flat has been described. However, the present invention is not limited to this structure. For example, the outer surface of the base portion 3121 can also be configured as a curved surface, and the deformable portion 3122 can be configured to protrude from the curved surface.

[0107] Furthermore, the case where the base portion 3121 and the protrusion 3122 are integrally formed has been described. However, the present invention is not limited to this structure. For example, the base portion 3121 and the protrusion 3122 can also be formed in two colors.

[0108] Furthermore, the case where a hanging hole 4a is formed on the hanging part 4 has been described. However, the present invention is not limited to this structure. For example, it is also possible to configure the device so that no hole is formed on the hanging part 4, and the device is hung by adsorption or interlocking with a magnet provided on a wall or the like.

[0109] Next, refer to Figures 14 to 24 The connector 5 for cleaning tools according to the second embodiment of the present invention will be described. The same reference numerals are used for structures identical to those in the first embodiment, and will not be described again.

[0110] The cleaning tool connector 5 of this embodiment connects a front end tube 6 located at the front end and a base end tube 7 located at the base end. Specifically, the cleaning tool connector 5 includes: a front end main body portion 51 inserted into the front end tube 6, a base end main body portion 52 inserted into the base end tube 7, and a connecting portion 53 connecting the front end main body portion 51 and the base end main body portion 52. In this embodiment, the connecting portion 53 is configured to abut against the end face of the front end tube 6 and the end face of the base end tube 7. Furthermore, the cleaning tool connector 5 of this embodiment connects tubes with approximately the same inner diameter. Moreover, the cleaning tool connector 5 of this embodiment connects the front end tube 6 and the base end tube 7 in a non-detachable manner.

[0111] The cleaning tool connector 5 of this embodiment has the same structure for its front end main body 51 and base end main body 52. ​​The front end main body 51 and base end main body 52 are provided symmetrically in the axial direction at the connecting part 53. Therefore, in this embodiment, the structure of the front end main body 51 will be described, and the detailed structure of the base end main body 52 will not be described again.

[0112] The front body portion 51 has a front base portion 511 with an outer diameter smaller than the inner diameter of the front tube body 6, and a front protrusion portion 512 that protrudes radially outward from the outer periphery of the front base portion 511. Furthermore, in the front body portion 51, the outer diameter of the portion where the front protrusion portion 512 is provided is larger than the inner diameter of the base end of the front tube body 6. Moreover, the front body portion 51 has a front pin insertion portion 513 at its front end, and this front pin insertion portion 513 is formed to supply pin P2 (see reference). Figure 23 The hole through which the pin is inserted is the front pin insertion hole 513a. Furthermore, the outer diameter of the portion having the front protrusion 512 refers to the outer diameter of the front protrusion 512.

[0113] The front end base 511 is a rod-shaped body extending in the axial direction. Furthermore, the front end base 511 is a rod-shaped body with an inner diameter smaller than the base end of the front end tube 6. In this embodiment, the front end base 511 is a rod-shaped body extending from the front end pin insertion portion 513 to the connecting portion 53. Moreover, the front end base 511 is a cylinder with a substantially constant outer diameter from the front end to the base end.

[0114] The front protrusion 512 is a protrusion that protrudes radially outward from the outer peripheral surface of the front base 511. Furthermore, the front protrusion 512 is deformable by abutting against the inner peripheral surface of the base end of the front tube body 6. Specifically, the front protrusion 512 has: a front base portion 5121 that protrudes radially outward from the outer peripheral surface of the front base 511; and a front deformable portion 5122 that protrudes radially outward from the outer peripheral surface of the front base portion 5121. The front deformable portion 5122 is deformable by abutting against the inner peripheral surface of the front end of the front tube body 6. In this embodiment, the front protrusion 512 extends in a direction intersecting both the axial and circumferential directions of the front base 511. Furthermore, the front protrusion 512 extends approximately within a circumferential range of the front body portion 51. Additionally, in this embodiment, a region 512a is formed on a portion of the front protrusion 512 in the circumferential direction where no protrusion (front deformable portion 5122) is formed in the axial direction. That is, a region without a protrusion is formed on a portion of the circumferential direction of the front protrusion 512, and this region extends along the axial direction. In other words, the front protrusion 512 is provided with a plurality of spiral protrusions (front deformation portion 5122) extending in less than one revolution in the circumferential direction. In addition, in this embodiment, the outer diameter of the region 512a is smaller than the inner diameter of the front tube body 6 (see reference). Figure 15 Therefore, the front protrusion 512 can be easily demolded from the mold. Moreover, the front protrusion 512 is a spiral protrusion on the outer peripheral surface of the front base 511. That is, the front protrusion 512 is a protrusion on the outer peripheral surface of the front base 511 in a manner that extends over a range of several circumferences in a direction that intersects both the axial direction and the circumferential direction.

[0115] like Figure 22 As shown, the front base portion 5121 is connected to the outer peripheral surface of the front base portion 511. Furthermore, the front base portion 5121 is a portion that extends radially outward from the outer peripheral surface of the front base portion 511. Moreover, the front base portion 5121 has a front base plane portion 5121a extending substantially parallel to the axis on its outer peripheral surface. Furthermore, the front base plane portion 5121a is a plane with a certain width in the axial direction. Moreover, the front base plane portion 5121a is provided throughout the entire outer peripheral surface of the front base portion 5121.

[0116] The front deformable portion 5122 is a portion that protrudes radially outward from the front base portion 5121. Furthermore, the front deformable portion 5122 is provided such that it protrudes radially outward from the front base plane portion 5121a. Moreover, the front deformable portion 5122 has a shape where the front end portion (the radially outward end) is thinner (shorter in axial length) than the base end portion (the connecting portion connected to the front base plane portion 5121a). In this embodiment, the front end portion 5122 has an arc-shaped front end. Furthermore, the front deformable portion 5122 of this embodiment is more easily deformable than the base end portion of the front tube body 6. Moreover, the front deformable portion 5122 is relatively softer than the front tube body 6, and therefore, it is easily deformable. Specifically, the radially outward end portion of the front deformable portion 5122 can abut against the inner circumferential surface of the front tube body 6 and deform in a manner that causes it to be crushed towards the base end side (radially inward).

[0117] The base body portion 52 has: a base portion 521 with an outer diameter smaller than the inner diameter of the base tube body 7, and a base protrusion 522 protruding radially outward from the outer periphery of the base portion 521. Furthermore, in the base body portion 52, the outer diameter of the portion with the base protrusion 522 is larger than the inner diameter of the front end of the base tube body 7. Moreover, the base body portion 52 has a base pin insertion portion 523 at the base end, which is formed to allow the insertion of a pin P2 (see reference 523). Figure 23 The hole through which the pin is inserted is the base pin insertion hole 523a.

[0118] like Figure 15 and Figure 16As shown, the base protrusion 522 has: a base base portion 5221 protruding radially outward from the base base portion 521, and a base deformation portion 5222 protruding radially outward from the base base portion 5221. The structure of the base base portion 5221 is the same as that of the front base portion 5121. The structure of the base deformation portion 5222 is the same as that of the front deformation portion 5122. That is, the base deformation portion 5222 abuts against the inner circumferential surface of the base tube body 7 and deforms by being crushed radially inward. Furthermore, in this embodiment, a region 522a is formed on a portion of the circumferential direction of the base protrusion 522 where no protrusion (base deformation portion 5122) is formed in the axial direction. In addition, in this embodiment, the outer diameter of this region 522a is smaller than the inner diameter of the base tube body 7. Therefore, the base protrusion 522 is easily demolded from the mold.

[0119] The structure and function of the above-described embodiments are summarized below.

[0120] With the cleaning tool connector 5 having the above-described structure, the front main body 51 and the inner circumferential surface of the tube body (front tube body 6) located on the front end side, and the base main body 52 and the inner circumferential surface of the tube body (base tube body 7) located on the base end side, are in close contact at at least two points separated in a direction including the axial direction. Therefore, it is possible to suppress the tube body located on the front end side from the tube body located on the base end side from wobbling and instability.

[0121] Furthermore, the front protrusion 512 and the base protrusion 522 extend in directions that intersect the axial direction and the circumferential direction. Therefore, compared to the case where the front protrusion 512 and the base protrusion 522 extend in the circumferential direction, it is easier to insert them into the tube body (front tube body 6) provided on the front end side and the tube body (base tube body 7) provided on the base end side.

[0122] Furthermore, the front end main body 51 is in close contact with the inner circumference of the front end tube 6 for approximately 100 minutes, and the base end main body 52 is in close contact with the inner circumference of the base end tube 7 for approximately 100 minutes. Therefore, the close contact force is unlikely to be uneven in the circumferential direction, thus suppressing the swaying and instability of the front end tube 6 and the base end tube 7.

[0123] Furthermore, the front protrusion 512 and the base protrusion 522 are spiral-shaped. Therefore, it is easy to insert the front main body 51 into the front tube 6 and the base main body 52 into the base tube 7, and the front protrusion 512 and the base protrusion 522 can reliably abut against the inner circumferential surfaces of the front tube 6 and the base tube 7.

[0124] Furthermore, there is a region 512a on the front main body 51 where no front protrusion 512 is provided in the axial direction, and there is a region 522a on the base main body 52 where no base protrusion 52 is provided in the axial direction. Therefore, when the front main body 51 and the base main body 52 are demolded from the mold and formed, it is easy to demold the front main body 51 and the base main body 52 from the mold.

[0125] Furthermore, the front main body 51 and the base main body 52 are symmetrically arranged in the axial direction via the connecting part 53. Therefore, it can be used even if the orientation of the cleaning tool connector 5 in the axial direction is reversed, improving operability.

[0126] The cleaning tool A and the cleaning tool connector 5 of the present invention have been described above by way of example. However, the present invention is not limited to the described embodiments, and various modifications can be made without departing from the spirit of the present invention. In addition, the cleaning tool A and the cleaning tool connector 5 of the present invention are not limited to the effects described above.

[0127] In the above embodiments, the front end main body portion 51 and the base end main body portion 52 have been described as being symmetrically arranged in the axial direction via the connecting portion 53. However, the present invention is not limited to this structure. For example, the front end main body portion 51 and the base end main body portion 52 can be configured asymmetrically in the axial direction. Furthermore, the outer diameter and axial length of the front end main body portion 51 and the base end main body portion 52 can be changed in conjunction with the front end tube body 6 and the base end tube body 7.

[0128] Furthermore, the illustration shows a case where holes extending through the axial direction are formed in the front end main body portion 51 and the base end main body portion 52. However, the structure is not limited to this. For example, holes extending through the axial direction may not be formed in the front end main body portion 51 and the base end main body portion 52.

[0129] Furthermore, the cleaning tool connector 5 is not limited to the shape shown in the figure. For example, the size of the cleaning tool connector 5 and the number of turns of the protrusions (front protrusion 512 and base protrusion 522) can be changed arbitrarily. The shape of the radial front end portion of the protrusions (front protrusion 512 and base protrusion 522) and the shape of the front end and base end of the cleaning tool connector 5 can also be changed arbitrarily.

[0130] Below, refer to Figures 25 to 35 The connector 5 for cleaning tools according to the third embodiment of the present invention will be described. Structures identical to those in the second embodiment will be labeled with the same reference numerals and will not be described repeatedly.

[0131] The cleaning tool connector 5 of this embodiment connects a front end tube 6 located at the front end and a base end tube 7 located at the base end. Specifically, the cleaning tool connector 5 includes: a front end main body portion 51 inserted into the front end tube 6, a base end main body portion 52 inserted into the base end tube 7, and a connecting portion 53 connecting the front end main body portion 51 and the base end main body portion 52. In this embodiment, the connecting portion 53 is configured to abut against the end face of the front end tube 6 and the end face of the base end tube 7.

[0132] The cleaning tool connector 5 of this embodiment has a different structure in its front end main body 51 and base end main body 52 compared to the second embodiment. Furthermore, in this embodiment, the front end main body 51 and base end main body 52 have the same structure and are symmetrically arranged in the connecting portion 53 along the axial direction. Therefore, in this embodiment, the structure of the front end main body 51 will be described, and the detailed description of the base end main body 52 will not be repeated. Additionally, the cleaning tool connector 5 of this embodiment connects pipes with approximately the same inner diameter to each other.

[0133] The front-end main body 51 has: a front-end base 511 with an outer diameter smaller than the inner diameter of the front-end tube 6, and a front-end deformable portion 5122 protruding radially outward from the outer periphery of the front-end base 511. That is, the front-end main body 51 of this embodiment does not have a front-end base portion. Furthermore, in the front-end main body 51, the outer diameter of the portion where the front-end deformable portion 5122 is provided is larger than the inner diameter of the base end of the front-end tube 6. Moreover, the front-end main body 51 has a front-end pin insertion portion 513 at its front end, which is formed to allow the insertion of a pin P2 (see reference 6). Figure 34 The through hole is the front pin insertion hole 513a.

[0134] The front end base 511 is a rod-shaped body extending in the axial direction. Furthermore, the front end base 511 is a rod-shaped body with an inner diameter smaller than the base end of the front end tube 6. In this embodiment, the front end base 511 is a rod-shaped body extending from the front end pin insertion portion 513 to the connecting portion 53. Moreover, the front end base 511 is a cylinder with an outer diameter that is approximately constant from the front end to the base end. Additionally, a hole is formed in the front end base 511 that extends through the axial direction from the front end to the base end.

[0135] The front deformation portion 5122 is a portion whose outer diameter front end abuts against the inner circumferential surface of the front end tube body 6 and deforms towards the inner diameter. Furthermore, the front deformation portion 5122 is a portion whose base end (the inner diameter end) is connected to the outer circumferential surface of the front end base 511 and protrudes outward from the outer circumferential surface of the front end base 511. Moreover, the front deformation portion 5122 has a shape where the front end (the outer diameter end) is thinner (shorter in axial length) than the base end (the connecting portion connected to the front end base 511). In this embodiment, the front end of the front deformation portion 5122 is semi-circular. Additionally, the front deformation portion 5122 in this embodiment is more easily deformed than the base end of the front end tube body 6. Specifically, the radial front end of the front deformation portion 5122 can abut against the inner circumferential surface of the front end tube body 6, thereby deforming in a manner that causes it to be crushed towards the base end side (inner diameter).

[0136] The base body portion 52 has a base portion 521 and a base deformation portion 5222. The structure of the base portion 521 is the same as that of the front end base portion 511. Furthermore, the structure of the base deformation portion 5222 is the same as that of the front end deformation portion 5122. Additionally, the base body portion 52 has a base pin insertion portion 523 at the base end, which is formed to allow the insertion of a pin P2 (see reference 5122). Figure 34 The through hole is the base pin insertion through hole 523a.

[0137] With the cleaning tool connector 5 having the structure described above, the deformable portion (front deformable portion 5122 and base deformable portion 5222) protrudes from the base (front base 511 and base base 521). Therefore, compared to the case where a base portion is provided, since the deformable portion is difficult to be pressed down in the axial direction, the deformable portion can be reliably brought into contact with the tube body.

[0138] The cleaning tool A and the cleaning tool connector 5 of the present invention have been described above by way of example. However, the present invention is not limited to the described embodiments, and various modifications can be made without departing from the spirit of the present invention. In addition, the cleaning tool A and the cleaning tool connector 5 of the present invention are not limited to the effects described above.

[0139] The cleaning tool connector 5 is not limited to the shape shown in the figure. For example, the size of the cleaning tool connector 5 and the number of turns of the protrusion (front end deformable part 5122 and base end deformable part 5222) can be arbitrarily changed. The shape of the radial front end portion of the protrusion (front end deformable part 5122 and base end deformable part 5222) and the shape of the front end and base end of the cleaning tool connector 5 can be arbitrarily changed.
