Problems to be Solved by the Invention

[0005] However, when using the cleaning tool of Patent Document 1 and strongly pressing the cleaning member against the object to be cleaned or repeating the sliding operation of the cleaning member, the cleaning member is likely to come off the cleaning tool body and may eventually come off.

[0006] An object of the present invention is to solve the above problems and provide a cleaning tool in which there is no risk that the cleaning body comes off from the attachment base portion of the main body portion.

Means for Solving the Problems

[0007] The cleaning tool according to the present invention for achieving the above objective is a cleaning tool comprising a handle portion and a cleaning portion continuous with the handle portion, wherein the cleaning portion comprises a main body portion disposed on the front end side, a connecting portion that connects one end on the front end side to the main body portion and the other end on the rear end side to the handle portion, and a cleaning body attached to the main body portion, wherein the main body portion comprises a flexible mounting base portion disposed on the front end side and an engaging portion continuous with the rear end of the mounting base portion that fixes the end of the cleaning body, and the engaging portion engages with an engaged portion provided on the front end side of the connecting portion. [Effects of the Invention]

[0008] According to the cleaning device of the present invention, the cleaning body will not detach from the mounting base even after prolonged use. Furthermore, since the cleaning body is strip-shaped, it can be wrapped around and secured regardless of the shape of the mounting base. [Brief explanation of the drawing]

[0009] [Figure 1] This is a perspective view of the cleaning tool according to this embodiment. [Figure 2] This is a disassembled perspective view of the main unit. [Figure 3] This is an exploded perspective view of the main unit with the cleaning body attached to the mounting base. [Modes for carrying out the invention]

[0010] The present invention will be described in detail below based on the illustrated embodiments. Figure 1 is a perspective view of the cleaning tool according to this embodiment, Figure 2 is an exploded perspective view of the main body, and Figure 3 is an exploded perspective view of the main body with the cleaning body attached to the mounting base.

[0011] The cleaning tool is molded from a rigid synthetic resin or the like and consists of a rod-shaped handle 1 and a cleaning section 2 that is continuous with the handle 1. The handle 1 is extendable and retractable, and a gripping section 1a is provided at its rear end. The handle 1 and the cleaning section 2 are connected via a rotating section 1b.

[0012] Furthermore, the handle 1 and the cleaning unit 2 may be directly connected without the rotating part 1b, and a handle 1 that does not extend or a handle 1 that is short, such as a handheld cleaning tool, can be used as appropriate.

[0013] The cleaning unit 2 consists of a main body 2a located at the front end, a connecting part 2b that connects one end at the front end to the main body 2a and the other end at the rear end to the handle 1, and a cleaning body 2c that is attached to the main body 2a.

[0014] The main body portion 2a is positioned at the front end and consists of a flexible, elongated plate-shaped mounting base portion 2d and an engaging portion 2e that is continuous with the rear end of the mounting base portion 2d and fixes the cleaning body 2c.

[0015] The engaging portion 2e is composed of a pair of engaging pieces 2f positioned on the outside and a rectangular parallelepiped plate-like portion 2g positioned between the pair of engaging pieces 2f, with a pair of groove-like gaps 2h positioned between the pair of engaging pieces 2f and the plate-like portion 2g. The engaging piece 2f is composed of a columnar portion 2i along the longitudinal direction of the mounting base 2d and a hook-shaped piece 2j continuous with the tip of the columnar portion 2i.

[0016] The tip of the connecting portion 2b is provided with an engaged portion 2k that engages with the engaging portion 2e of the main body portion 2a. This engaged portion 2k has a cylindrical shape into which a pair of engaging pieces 2f and a plate-like portion 2g can be inserted. On the side wall of the engaged portion 2k, a pair of engaging holes 2l are provided opposite each other, into which a pair of hook pieces 2j engage.

[0017] Although the engagement hole 2l penetrates the side wall of the engaged portion 2k, a non-penetrating structure may be adopted in which recesses are formed on the inner surface of the engaged portion 2k and the engagement piece 2f engages with these recesses. Furthermore, the engaged portion 2k can be in any shape other than cylindrical, such as a pair of parallel plates with engagement holes, but a cylindrical shape is preferred considering the strength of the engaged portion 2k against impact and the damage to the engaging portion 2e due to impact.

[0018] At the other end of the connecting part 2b, a rotating body 2m that constitutes the rotating part 1b is provided via a curved part. The rotating part 1b can adjust the cleaning part 2 to an arbitrary angle while obtaining a clicking feeling during rotation. Furthermore, the handle part 1 and the cleaning part 2 can also be in an opposing state in order to be compact and storable during storage.

[0019] The cleaning body 2c is in a strip shape with its surface covered by hair-like bodies such as fiber hairs, and is wound around and fixed to the periphery of the mounting base 2d as shown in the figure. The method of attaching the cleaning body 2c to the main body part 2a is as follows: First, an adhesive or the like is stored in the through hole 2n at the tip of the mounting base 2d, and one end of the cleaning body 2c is fixed.

[0020] Next, while moving the cleaning body 2c in the state where one end is fixed to the rear end side, tension is applied and it is wound around the mounting base 2d. Although the tip of the cleaning body 2c is fixed to the mounting base 2d with an adhesive or the like, at the locations where a part of the cleaning body 2c other than that is wound while overlapping, it is not necessary to adhere with an adhesive or the like.

[0021] After winding the cleaning body 2c to the rear end of the mounting base 2d, the other end of the cleaning body 2c is attached to the engaging part 2e. The method of attaching the other end of the cleaning body 2c is to insert the end of the cleaning body 2c into the pair of groove-shaped voids 2h from a direction perpendicular to the longitudinal direction of the cleaning body 2c respectively and fix it.

[0022] Note that the groove width of the groove-shaped void 2h is substantially the same as the thickness of the cleaning body 2c or slightly narrower than the thickness of the cleaning body 2c. Therefore, after insertion, the cleaning body 2c will be sandwiched by the groove-shaped void 2h. Also, the other end of the cleaning body 2c may be fixed by winding it around the plate-shaped part 2g, as long as the thickness of the wound cleaning body 2c is substantially the same as the groove width of the groove-shaped void 2h or the thickness of the wound cleaning body 2c is slightly thicker than the groove width of the groove-shaped void 2h.

[0023] As shown in Figure 3, the other end of the cleaning body 2c is clamped in the groove-shaped gap 2h between the engaging piece 2f and the plate-shaped part 2g, and then the engaging part 2e is inserted into the engaged part 2k of the connecting part 2b. Then, as shown in Figure 1, the engaging part 2e is pushed into the engaged part 2k until the hook pieces 2j of the pair of engaging pieces 2f each engage with the pair of engaging holes 2l.

[0024] When the hook piece 2j engages with the engagement hole 2l, the main body 2a will not detach from the connecting part 2b unless the hook piece 2j is pressed inward with a pin or the like. In this way, the attachment of the cleaning body 2c to the main body 2a is completed.

[0025] Furthermore, the side walls of the engaged portion 2k constantly restrict the column portion 2i from spreading laterally. As a result, the clamping force of the engaging piece 2f and plate-like portion 2g on the end of the cleaning body 2c does not decrease.

[0026] Therefore, even if the cleaning body 2c, which is wound around the easily flexible mounting base 2d, is brought into strong contact with the object to be cleaned, the cleaning body 2c will not detach from its rear end. If the rear end of the cleaning body 2c were to detach from the mounting base 2d, the wound state would easily unravel from the detached cleaning body 2c.

[0027] In contrast, if the tip of the cleaning body 2c detaches from the mounting base 2d, the cleaning body 2c is wound while being moved towards the rear end, so the detached cleaning body 2c is not further unwound by the adjacent overlapping cleaning bodies 2c, and the wound state is maintained.

[0028] As described above, the winding state of the cleaning body 2c can be easily undone from the mounting base 2d at the rear end of the cleaning body 2c, and the cleaning body 2c can be easily replaced by releasing the engagement between the main body 2a and the connecting part 2b. For example, it is preferable to replace the cleaning body 2c when the bristles on the surface of the cleaning body 2c wear down and the suction force decreases.

[0029] Thus, with the cleaning device according to the present invention, the cleaning body 2c will not detach from the mounting base 2d even if used for a long period of time. Furthermore, the mounting base 2d of the cleaning unit 2 can be made into an appropriate shape depending on the application, such as an elongated shape, a wide shape, or an elliptical shape, and the strip-shaped cleaning body 2c can be wrapped around and fixed regardless of the shape of these mounting bases 2d.
