Description

[Technical field]

[0001] The present invention relates to a cleaning tool such as a toilet brush, and in particular to a cleaning tool having a cleaning element at the end of a handle, and a storage case for the cleaning tool that houses it. [Background technology]

[0002] An example of the above-mentioned cleaning tool is a toilet cleaner as shown in Patent Document 1. The handle of this toilet cleaner is composed of an upper straight handle part having a grip and a lower arc-shaped handle part extending downward from the tip of the base-side straight handle part while curving in an arc on the front side of the handle front side of the extension line of the upper straight handle part. The middle part of the core part of the cleaning body is attached to the tip of the lower arc-shaped handle part in a front-down inclined position located downward toward the front end side, and the front end part of the core part is bent upward.

[0003] The storage case for storing the toilet cleaner has a circular bottom wall and a cylindrical peripheral wall rising from the periphery of the bottom wall. An engagement recess is formed at the lower end of the rear surface of the upper straight handle portion of the handle, which can engage from above with the upper opening edge of the peripheral wall of the storage case. When the engagement recess of the handle is engaged with the upper opening edge of the storage case, the cleaning body of the toilet cleaner is stored and held in a state spaced apart from the inner surfaces of the peripheral wall and the bottom wall of the storage case.

[0004] [Patent Document 1] Patent No. 6276953 Summary of the Invention [Problem to be solved by the invention]

[0005] In the toilet cleaner described above, the lower arc-shaped handle portion of the handle curves and protrudes in a substantially circular arc shape on the handle front side beyond the extension line of the substantially straight upper straight handle portion, so that, for example, when cleaning the water seal portion 72 of the drainage channel 71 of the toilet bowl 70 shown in Fig. 10, the lower arc-shaped handle portion of the handle is likely to interfere with the front wall portion 74 constituting the weir 73 of the water seal portion 72. Also, even if the core portion of the cleaning body is configured in a downwardly inclined position toward the front end of the lower arc-shaped handle portion, there is a problem in that the cleaning range of the water seal portion 72 of the toilet bowl 70 is limited.

[0006] Furthermore, when the engaging recess formed on the lower end of the rear surface of the upper straight handle portion of the handle is engaged with the upper opening edge of the storage case, a moment is generated in the toilet cleaner in a direction that brings the cleaning body closer to the inner surface of the peripheral wall of the storage case, and the toilet cleaner is likely to swing when the storage case is moved.

[0007] In view of this situation, a main object of the present invention is to provide a cleaning tool that can easily clean the inner side of the water seal of a toilet bowl, and a storage case for the cleaning tool that is suitable for storing the cleaning tool. [Means for solving the problem]

[0008] The first characteristic feature of the present invention is a cleaning tool having a cleaning body at the tip of a handle, The handle is equipped with a substantially straight base-side straight handle portion having a gripping portion, and a tip-side arcuate handle portion which extends from the tip of the base-side straight handle portion toward the front of the handle, curving or bending in a substantially arc shape, on the rear side of the handle from the extension line of the base-side straight handle portion.

[0009] According to this configuration, the arcuate handle tip portion of the handle extends from the tip of the base-side straight handle portion toward the front side of the handle, curving or bending in an approximately arc shape, on the rear side of the handle from the extension line of the approximately straight base-side straight handle portion, so that, for example, when cleaning the water seal portion 72 of the drainage channel 71 of the toilet 70 shown in Figure 10, the arcuate handle tip portion of the handle can be easily prevented from interfering with the front wall portion 74 constituting the weir 73 of the water seal portion 72. Therefore, the cleaning body at the tip of the handle can be easily inserted into the back side of the water seal portion 72 of the toilet 70, so the cleaning range of the water seal portion 72 of the toilet 70 can be expanded.

[0010] A second characterizing feature of the present invention is that the cleaning element is attached to the tip of the tip side arcuate handle in a position substantially along the arc extension direction of the tip side arcuate handle.

[0011] According to this configuration, the cleaning body extends toward the front side of the handle in a position that is approximately along the arc extension direction of the tip-side arc-shaped handle portion, so that the cleaning range of the toilet's water seal portion can be expanded while the tip-side arc-shaped handle portion can be shortened, thereby reducing the manufacturing costs of the handle.

[0012] The third characteristic configuration of the present invention is that the cleaning body has the length and flexibility to cover the entire circumference, including the upper and lower surfaces, of the cleaning support part attached to the tip of the tip side arc-shaped handle part in a single ring shape, and is provided with a pressing and fixing part that presses and fixes the end of the cleaning body against the cleaning support part from the outside.

[0013] According to this configuration, the cleaning body is wound around the cleaning support part in a single ring shape, so there is no waste of material for the cleaning body. Moreover, the cleaning body wound around the cleaning support part can be configured compactly while ensuring the circumferential length of the cleaning surface on the outer circumferential side. Moreover, because the end of the cleaning body is pressed and fixed from the outside to the cleaning support part by the pressing and fixing part, it is possible to reduce the need to drill holes for fixing the cleaning body, and the cost of the cleaning tool can be reduced.

[0014] A fourth characteristic configuration of the present invention is a cleaning tool storage case for storing the cleaning tool according to any one of the first to third characteristic configurations, The cleaning tool has an upwardly opening storage section having a bottom wall section and a peripheral wall section rising from around the bottom wall section, and a handle holding section standing from the peripheral wall section and holding in an engaged state the base end straight handle section of the cleaning tool in a vertical orientation with the cleaning body housed within the peripheral wall section, and the handle holding section is provided with an abutment section that abuts against the front surface of the base end straight handle section.

[0015] According to this configuration, when the cleaning tool is stored, the base straight handle of the cleaning tool is fitted and held by the handle holding part that stands upright from the peripheral wall of the upper opening storage part. In this fitted and held state, the shifting movement of the handle of the cleaning tool stored in a vertical position can be restricted by abutment with the inner surface of the handle holding part. Moreover, a moment is generated in the fitted and held cleaning tool in a direction approaching a portion of the inner surface of the peripheral wall of the storage case that corresponds to the extension line of the base straight handle, due to the tip arcuate handle that is curved or bent in an approximately arc shape on the handle rear side from the extension line of the base straight handle. This moment keeps the front surface of the base straight handle in abutment with the abutment part of the handle holding part, so that rattling of the cleaning tool when the storage case is moved can be suppressed.

[0016] The fifth characteristic configuration of the present invention is that an engagement recess is formed at the upper end of the handle holding part with which an engagement protrusion provided on the base end straight handle portion of the cleaning tool can engage from above and below, and when the engagement protrusion engages with the engagement recess and the front surface of the base end straight handle portion abuts against the abutment portion of the handle holding part, the cleaning body is stored and held in a state spaced apart from the inner surface of the peripheral wall portion and the inner surface of the bottom wall portion.

[0017] With this configuration, by simply engaging from above the engagement protrusion provided on the base end straight handle portion of the cleaning tool with the engagement recess formed on the upper end of the handle holding portion of the storage section, the cleaning tool can be stably held in a vertical storage position with the cleaning body separated from the inner surfaces of the peripheral wall portion and the bottom wall portion of the storage section by the engagement and retention between the handle holding portion and the base end straight handle portion and the moment.

[0019] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a cleaning tool A suitable for use in cleaning toilet bowls, and a storage case B for storing it. As shown in Figs. 1 to 3, the cleaning tool A is equipped with a synthetic resin handle 1, a synthetic resin cleaning support part 2 attached to the tip of the handle 1, and a flexible cleaning body 3 that covers the entire periphery, including the upper surface 21a and lower surface 21b, of a cleaning support main body 21, which is a component of the cleaning support part 2.

[0020] As shown in Fig. 1 and Fig. 2, the handle 1 of the cleaning tool A includes a substantially straight base-side straight handle portion 11 having a grip portion 10, and a tip-side arcuate handle portion 12 extending from the tip of the base-side straight handle portion 11 toward the handle front side FC while curving or bending in a substantially arc shape on the handle rear side RC from the extension line of the rear surface 11b of the base-side straight handle portion 11. The cleaning support body 21 also serves as a part of the handle 1, and is attached to the tip of the tip-side arcuate handle portion 12 in a position substantially along the arcuate extension direction of the tip-side arcuate handle portion 12. Therefore, the cleaning body 3 covering the entire circumference of the cleaning support body 21 is also configured in a position substantially along the arcuate extension direction of the tip-side arcuate handle portion 12. The tip of the cleaning body 3 is located on or near the extension line of the rear surface 11b of the base-side straight handle portion 11.

[0021] As described above, the distal arcuate handle portion 12 of the handle 1 extends from the distal end of the proximal straight handle portion 11 toward the handle front side FC while curving or bending in a substantially arc shape on the handle rear side RC beyond the extension line of the rear surface 11b of the proximal straight handle portion 11. With this configuration, for example, as shown in Fig. 10, when cleaning the water seal portion 72 of the drainage channel 71 of the toilet 70, the distal arcuate handle portion 12 of the handle 1 can be easily prevented from interfering with the front wall portion 74 constituting the weir 73 of the water seal portion 72. Therefore, the cleaning body 3 attached to the distal end of the handle 1 can be easily inserted into the back side of the water seal portion 72 of the toilet 70, so that the cleaning range of the water seal portion 72 of the toilet 70 can be expanded.

[0022] Furthermore, since the cleaning body 3 is extended toward the handle front side FC in a position that is approximately along the arc extension direction of the tip end arc-shaped handle portion 12, the cleaning range of the water sealing portion 72 of the toilet 70 can be expanded while the tip end arc-shaped handle portion 12 can be shortened, thereby reducing the manufacturing cost of the handle 1.

[0023] As shown in Fig. 2, the gripping part 10 comprises a front gripping body 10A having a substantially U-shaped horizontal cross section that opens rearward, and a rear gripping body 10B having a substantially U-shaped horizontal cross section that opens forward. The lower end of the front gripping body 10A is integrally formed with the upper end of the base end straight handle portion 11. Reinforcing plate portions 10C perpendicular to the front surface 10a of the front gripping body 10A are integrally formed at multiple positions (three positions in this embodiment) above and below the front gripping body 10A.

[0024] As shown in Fig. 2(b), the rear gripping body 10B is configured to be freely fitted and attached to the front gripping body 10A from the rear. To this end, a first engagement claw 10D capable of bending and deforming inwardly in the width direction is integrally formed at the opening ends on both sides in the width direction of the front gripping body 10A. A second engagement claw 10E capable of bending and deforming outwardly in the width direction is integrally formed at the opening ends on both sides in the width direction of the rear gripping body 10B. When the rear gripping body 10B is fitted and attached to the front gripping body 10A from the rear, the first engagement claw 10D and the second engagement claw 10E engage while bending and deforming.

[0025] 1 to 3, grip portion 10 has a rectangular cross section with a front-to-rear dimension slightly larger than its left-to-right dimension. Base end straight handle portion 11 and tip end arcuate handle portion 12 also have rectangular cross sections with a front-to-rear dimension slightly larger than their left-to-right dimensions. 1 to 3, the front-to-rear dimension D1 of the lower end of grip portion 10 is slightly larger than the front-to-rear dimension D2 of the upper end of base-side straight handle portion 11. Therefore, a horizontal front step surface 13a is formed between the lower end of the front surface 10a of grip portion 10 and the upper end of the front surface 11a of base-side straight handle portion 11. The front-to-rear dimension of this front step surface 13a is configured to be the same or approximately the same as the thickness of a front wall portion 53A of handle holding portion 53 of storage case B, which will be described later.

[0026] 1 to 3, the left-right dimension W1 of the lower end of the grip portion 10 is slightly larger than the left-right dimension W2 of the upper end of the base-side straight handle portion 11. Therefore, a horizontal lateral step surface 13b is formed between the lower ends of the left and right side surfaces 10b of the grip portion 10 and the upper ends of the left and right side surfaces 11c of the base-side straight handle portion 11. The left-right dimension of this lateral step surface 13b is configured to be the same or approximately the same as the thickness of the side wall portions 53B of the handle holding portion 53 of the storage case B described below. The front step surface 13a and the left and right side step surfaces 13b are configured so as to be able to be placed on the upper end surface 53a of the front wall portion 53A of the handle holding portion 53 and the upper end surfaces 53b of the left and right side wall portions 53B.

[0027] 1 and 2, the storage case B includes an upwardly opening storage section 52 having a bottom wall section 50 having a rectangular shape in a plan view and a peripheral wall section 51 rising from the periphery of the bottom wall section 50. The peripheral wall section 51 of the storage section 52 includes an inner peripheral wall section 51A integrally formed from the periphery of the bottom wall section 50 toward the upper side, an inclined upper wall section 51B integrally formed from the upper end of the inner peripheral wall section 51A toward the upper outward side, and an outer peripheral wall section 51C integrally formed from the outer peripheral edge of the inclined upper wall section 51B toward the lower side. The lower end of the outer peripheral wall section 51C stably contacts the ground while protruding downward from the lower surface of the bottom wall section 50.

[0028] As shown in Figures 1 and 2, of the inclined upper wall 51B of the storage section 52, the front upper wall portion 51Ba on the front side is wider than the lateral upper wall portions 51Bb on the left and right lateral sides and the rear upper wall portion 51Bc on the rear side. A handle holder 53 having a substantially U-shaped horizontal cross section that opens rearward is provided in a left-right central portion of the front upper wall portion 51Ba. This handle holder 53 holds, in a fitted state, the base-side straight handle portion 11 of the cleaning tool A in a vertical orientation with the cleaning body 3 stored in the storage space 55 formed by the bottom wall 50 and the inner peripheral wall 51A. 1 and 2, the handle holding portion 53 is formed with a length (height dimension) that allows it to be held comfortably in one hand, and functions as a handle for carrying the storage case B. In other words, the handle holding portion 53 is configured as a handle.

[0029] The handle holding portion 53 has a front wall portion 53A and left and right side walls portion 53B. The horizontal upper end surface 53a of the front wall portion 53A and the horizontal upper end surfaces 53b of the left and right side walls portion 53B of the handle holding portion 53 are configured as mounting surfaces for the front step surface 13a and the left and right lateral step surfaces 13b of the handle 1. The inner dimension between the opposing surfaces of the left and right side walls portion 53B is configured to be slightly larger than the dimension between the outer surfaces of the left and right side surfaces 11c of the base end straight handle portion 11 of the cleaning tool A. The inner surface of the front wall 53A of the handle holding part 53 forms an abutment part 54 that abuts against the front surface 11a of the base-side straight handle part 11 of the cleaning tool A. The inner surface of the front wall 53A of the handle holding part 53 and the front surface 11a of the base-side straight handle part 11 come into contact with each other in a face-to-face manner.

[0030] The front step surface 13a and the left and right side step surfaces 13b of the handle 1 are placed on the upper end surfaces 53a, 53b of the handle holding part 53, so that the base end straight handle portion 11 of the cleaning tool A is fitted and held in the handle holding part 53. In this fitted and held state, the forward and left-right movement of the handle 1 of the cleaning tool A is restricted by the inner surface of the front wall portion 53A and the inner surfaces of the left and right side walls 53B of the handle holding part 53. This makes it possible to hold the handle 1 of the cleaning tool A, which is stored in a vertical position, with little wobble.

[0031] Moreover, in the fitted and held cleaning tool A, a moment is generated in a direction approaching a portion of the inner surface of the inner peripheral wall 51A that corresponds to the extension line of the rear surface 11b of the base straight handle portion 11, due to the tip arcuate handle portion 12 that is curved or bent in an approximately arc shape on the handle rear side RC further than the extension line of the rear surface 11b of the base straight handle portion 11. This moment keeps the front surface 11a of the base straight handle portion 11 in contact with the contact portion 54, which is the inner surface of the front wall 53A of the handle holding part 53, thereby preventing the cleaning tool A from rattling when the storage case B is moved.

[0032] A generally U-shaped engagement recess 56 that opens upward and toward the inside is formed at the upper end of the left and right side walls 53B of the handle holding part 53. An engagement protrusion 57 that engages with the left and right engagement recesses 56 of the handle holding part 53 from above is formed at the upper end of the left and right side surfaces 11c of the base-side straight handle part 11. When the engaging protrusion 57 of the base end straight handle portion 11 of the cleaning tool A engages with the engaging recess 56 of the handle holding portion 53 of the storage case B from the top and bottom directions and the front surface 11a of the base end straight handle portion 11 of the cleaning tool A abuts against the abutment portion 54, which is the inner surface of the front wall portion 53A of the handle holding portion 53, the cleaning body 3 is stored and held within the storage space 55 in a state spaced apart from the inner surface of the inner peripheral wall portion 51A and the inner surface of the bottom wall portion 50.

[0033] By simply engaging the engagement protrusion 57 of the base end straight handle portion 11 of the cleaning tool A from above with the engagement recess 56 of the handle holding portion 53 of the storage case B, the cleaning body 3 can stably hold the cleaning tool A in a vertical storage position with the cleaning tool 3 spaced apart from the inner surface of the inner peripheral wall portion 51A and the inner surface of the bottom wall portion 50 of the storage section 52 by the engagement between the handle holding portion 53 and the base end straight handle portion 11 and the moment.

[0034] Next, the mounting structure of the cleaning body 3 of the cleaning tool A will be described in detail. As shown in Fig. 1 and Fig. 8, the cleaning body 3 is attached to the cleaning support body 21 in a single ring shape with both end faces 3a, 3b in the longitudinal direction butted against each other. As shown in Fig. 1 and Fig. 8, both end faces 3a, 3b of the cleaning body 3 are arranged in a substantially linear portion offset toward the tip end of the handle 1 on the upper surface 21a of the cleaning support body 21. The both end faces 3a, 3b of the cleaning body 3 in the butted state are bonded to each other with an adhesive. Furthermore, a pressing and fixing part 4 is provided which presses and fixes at least both end parts 3A, 3B of the cleaning body 3 in the butted state to the cleaning support body 21 from the outside.

[0035] As described above, the cleaning body 3 is wound around the cleaning support body 21 of the cleaning support part 2 in a single ring shape with both end faces 3a, 3b in the longitudinal direction butted against each other, so there is no waste of material for the cleaning body 3 compared to, for example, a case where a cleaning body 3 longer than the entire circumferential length of the cleaning support body 21 is wound around with both end parts overlapping each other. In addition, the cleaning body 3 wound around the cleaning support body 21 can be compactly configured while ensuring the circumferential length of the cleaning surface on the outer circumferential side. Moreover, since both end parts 3A, 3B of the cleaning body 3 in the butted state are pressed and fixed from the outside to the cleaning support body 21 by the pressing and fixing part 4, it is possible to reduce the need to make holes for fixing the cleaning body 3, and the cost of the cleaning tool A can be reduced.

[0036] Next, the configuration of each part of the cleaning tool A will be described in detail. At the tip of the distal end arcuate handle portion 12 of the handle 1, as shown in Fig. 9, a connection port 14 with a horizontally elongated rectangular cross section that opens onto the distal end surface is formed. A square-shaft-shaped handle attachment portion 22 formed integrally with the base end of the cleaning support body 21 of the cleaning support part 2, which will be described later, and a square-shaft-shaped handle attachment portion 42 formed integrally with the base end of the pressing body 41 of the pressing and fixing part 4 are fitted and attached to this connection port 14 of the distal end arcuate handle portion 12 in an overlapping state so as to be free only to slide.

[0037] 9, a first through hole 15 is formed in the middle of the region in which the connection port 14 is formed in the tip-side arcuate handle 12, penetrating in a horizontal width direction perpendicular to the fitting and mounting direction of the handle attachment part 22 of the cleaning support part 2. As shown in Fig. 8, the handle attachment part 22 of the cleaning support part 2 is formed with a second through hole 23 that communicates in the width direction with the first through hole 15 of the tip-side arcuate handle 12 when inserted into a predetermined fitting position in the connection port 14. Then, as shown in Figs. 6 and 7, a pin-shaped retaining member 5 that prevents the handle attachment part 22 of the cleaning support body 21 from coming off is detachably inserted between the first through hole 15 of the tip-side arcuate handle 12 and the second through hole 23 of the handle attachment part 22 of the cleaning support part 2.

[0038] As shown in Figs. 4 to 6, the cleaning support part 2 includes a plate-shaped cleaning support body 21 formed in a generally rectangular outline shape in plan view, and a square-shaft-shaped handle attachment part 22 extending integrally from the widthwise center of the base-side short side of the cleaning support body 21 at an inclination angle of approximately 45 degrees. As shown in Fig. 7, the cleaning support body 21 is configured to have a width smaller than the width of the cleaning body 3. In addition, as shown in Figs. 2 and 5, the front end part 21A of the cleaning support body 21 is curved upward (toward the upper surface 21a of the cleaning support body 21) at an angle of approximately 90 degrees. The curved front end part 21A of the cleaning support body 21 makes it easy to clean the back side of the edge (sometimes called a rim) that protrudes toward the center of the upper opening of the toilet bowl.

[0039] As shown in Figs. 4 to 6, a cone-shaped sharp first small protrusion 24 capable of biting into the inner surface of the cleaning body 3 is integrally formed at each of two locations spaced apart in the long side direction on both sides of the upper surface 21a of the cleaning support body 21 in the width direction. A cone-shaped sharp second small protrusion 25 capable of biting into the inner surface of the cleaning body 3 is integrally formed at each of two locations spaced apart in the long side direction on both sides of the lower surface 21b of the cleaning support body 21 in the width direction. A cone-shaped sharp third small protrusion 26 capable of biting into the inner surface of the cleaning body 3 is integrally formed at each of both sides of the tip surface 21c of the curved front end 21A of the cleaning support body 21 in the width direction. The first small protrusion 24, the second small protrusion 25, and the third small protrusion 26 are each configured to have the same or approximately the same protruding height. Each of the first small protrusions 24 is configured to have a gently inclined posture with the tip side slightly inclined toward the base end of the cleaning support body 21 with respect to a vertical line passing through the center of the protrusion base. Each of the second small protrusions 25 is configured to have a gently inclined posture with the tip side slightly inclined toward the tip end of the cleaning support body 21 with respect to a vertical line passing through the center of the protrusion base. Each of the third small protrusions 26 is configured to have a substantially perpendicular posture with respect to the tip surface 21c of the curved front end portion 21A of the cleaning support body 21.

[0040] 4 to 6, a cone-shaped sharp claw portion 27 extending toward the pressing surface 41a of the pressing body 41 is integrally formed at the center of the cleaning support body 21 in the width direction and at a portion corresponding to the tip of the pressing surface 41a of the pressing body 41 of the pressing and fixing part 4. This claw portion 27 is more than twice as high as the protruding height of the first small protrusion 24, and its tip is located near the pressing surface 41a of the pressing body 41. In addition, the tip side of the claw portion 27 is inclined toward the base end side of the cleaning support body 21 with respect to a vertical line passing through the center of the claw root, and is configured at an inclination angle larger than the inclination angle of the first small protrusion 24. A rectangular punch hole 28 for forming the claw portion 27 is formed through the cleaning support body 21 at the center in the width direction.

[0041] 2 and 9, when the pressing body 41 presses the outer surfaces of both end portions 3A, 3B of the cleaning body 3, the claws 27 extending from the cleaning support part 2 toward the pressing surface 41a of the pressing body 41 bite into the cleaning body 3, and at the same time, the clamping force of the cleaning body 3 between the pressing surface 41a of the pressing body 41 and the claws 27 becomes stronger. As a result, the cleaning body 3 can be firmly clamped and fixed without any shifting movement, even with a simple mounting structure in which the pressing body 41 presses the area covering the outer surfaces of both end portions 3A, 3B of the cleaning body 3 toward the upper surface 21a of the cleaning support main body 21.

[0042] As shown in Figs. 4 to 6, the handle attachment part 22 of the cleaning support part 2 has a height and width greater than the thickness of the cleaning support body 21, and is configured in the shape of a rectangular square shaft with a horizontally elongated cross section. The width of the handle attachment part 22 of the cleaning support part 2 is set to a dimension slightly smaller than the width of the connection port 14 of the distal end arc-shaped handle part 12. The height of the handle attachment part 22 of the cleaning support part 2 is set to a dimension smaller than the height of the connection port 14 of the distal end arc-shaped handle part 12. Therefore, when the handle attachment part 22 of the cleaning support part 2 is inserted into a predetermined fitting position in the connection port 14, a fitting space is formed between the upper surface of the handle attachment part 22 and the ceiling surface of the connection port 14, in which the handle attachment part 42 of the pressing and fixing part 4 can be freely fitted and attached in a sliding state.

[0043] 4, 5 and 9, the upper surface of the handle attachment part 22 of the cleaning support part 2 is configured so as to be able to overlap in the height direction with the lower surface of the handle attachment part 42 of the pressing fix part 4. The overlapping contour shape of the handle attachment part 22 of the cleaning support part 2 and the handle attachment part 42 of the pressing fix part 4 is configured to be similar to but slightly smaller than the inner contour shape of the connection port 14 of the tip side arcuate handle part 12. At the overlapping portion between the handle attachment part 22 of the cleaning support part 2 and the handle attachment part 42 of the pressing fixation part 4, as shown in Figures 4, 5 and 9, a positioning engagement part 6 that engages from the overlapping direction is provided. This engagement part 6 has a semicircular engagement groove 6A formed along the width direction on the upper surface of the handle attachment part 22 of the cleaning support part 2, and a semicircular engagement protrusion 6B formed along the width direction on the lower surface of the handle attachment part 42 of the pressing fixation part 4. As shown in Figure 9, the engagement depth between the engagement groove 6A and the engagement protrusion 6B is set to an engagement allowance that is sufficiently larger than the gap between the inner surface of the connection port 14 of the tip side arcuate handle part 12 and the outer surfaces of the handle attachment part 22 of the cleaning support part 2 and the handle attachment part 42 of the pressing fixation part 4 inserted in an overlapping state.

[0044] 9, the handle attachment part 22 of the cleaning support part 2 and the handle attachment part 42 of the pressing and fixing part 4 are fitted and attached in an overlapping state to the connection port 14 of the tip-side arcuate handle part 12 of the handle 1. In this state, the engagement groove 6A and the engagement protrusion 6B of the engagement part 6 provided at the overlapping part of both handle attachment parts 22, 42 are engaged from the overlapping direction, and the relative movement of both handle attachment parts 22, 42 in the fitting and mounting direction is prevented. Therefore, by simply inserting the pin-shaped retaining member 5 across the first through-hole 15 of the tip-side arcuate handle part 12 and the second through-hole 23 of the handle attachment part 22 of the cleaning support body 21, it is possible to reliably prevent both handle attachment parts 22, 42 from slipping out of the connection port 14 of the handle 1. Therefore, the retaining structure between the handle attachment part 42 of the pressing and fixing part 4 and the handle attachment part 22 of the cleaning support part 2 can be simplified.

[0045] 4 to 6 and 9, the pressing and fixing part 4 includes a flat pressing body 41 capable of pressing from the outside an area covering the outer surfaces of both ends 3A, 3B of the cleaning body 3, and a handle attachment part 42 extending integrally at an inclination angle of about 45 degrees from the center in the width direction of the base end short side of the pressing body 41. The width of the pressing body 41 is the same or about the same as the width of the cleaning support main body 21, as shown in FIG. As shown in Figures 5 and 9, when the handle mounting portion 42 of the pressing fixed portion 4 and the handle mounting portion 22 of the cleaning support part 2 are fitted and attached to the connection port 14 of the handle 1 in an overlapping state, the opposing surface distance W between the cleaning support main body 21 and the pressing body 41 is configured to a clamping distance that fixes both end portions 3A, 3B of the cleaning body 3 in a pressing state.

[0046] 9, when the handle attachment part 42 of the pressing and fixing part 4 and the handle attachment part 22 of the cleaning support part 2 are inserted into a predetermined fitting position in the connection port 14 of the handle 1 while overlapping each other, the base end surface 41b of the pressing body 41 abuts against the tip surface 12a of the ceiling wall 12A that constitutes the connection port 14 of the tip side arcuate handle part 12. In other words, the base end surface 41b of the pressing body 41 is configured as an insertion position regulating surface that regulates both handle attachment parts 22, 42 to the predetermined fitting position.

[0047] 9, the handle attachment part 42 of the pressing and fixing part 4 and the handle attachment part 22 of the cleaning support part 2 are overlapped, and the overlapped handle attachment parts 22, 42 are fitted and attached to the connection port 14 of the handle 1. As a result, the opposing surface distance W between the upper surface 21a of the cleaning support main body 21 and the pressing surface 41a of the pressing body 41 becomes the clamping distance for pressing and fixing both ends 3A, 3B of the cleaning body 3, so that the fixing work of the cleaning body 3 can be performed quickly and easily.

[0048] 7, the cleaning body 3 is made of a mat-like material such as nonwoven fabric with relatively firm elasticity, and is attached to the cleaning support body 21 by wrapping it around in a single ring shape with both longitudinal end faces 3a, 3b butted against each other. At one longitudinal end of the cleaning body 3 and at the center in the width direction, an attachment hole 31 is formed through which the handle attachment part 42 of the pressing and fixing part 4 and the handle attachment part 22 of the cleaning support part 2 are inserted in an overlapping state. In this embodiment, the cleaning element 3 has an outer surface layer to which a cleaning treatment agent containing fluororesin powder is adhered.

[0049] [Another embodiment] (1) In the above embodiment, the retaining member 5 is provided between the distal end arcuate handle portion 12 of the handle 1 and the handle attachment portion 22 of the cleaning support portion 2 to prevent the handle attachment portion 22 of the cleaning support portion 2 from coming off, but is not limited to this retaining structure. For example, the retaining member 5 may be provided between the distal end arcuate handle portion 12 of the handle 1 and the handle attachment portion 42 of the pressing fixation portion 4 to prevent the handle attachment portion 42 of the pressing fixation portion 4 from coming off.

[0050] (2) In the above embodiment, the handle attachment part 22 of the cleaning support part 2 and the handle attachment part 42 of the pressing fixation part 4 are configured to be able to be fitted and attached freely in an overlapping state to the connection port 14 at the tip of the handle 1, but the present invention is not limited to this attachment structure. For example, the handle attachment part 22 of the cleaning support part 2 may be integrally formed at the tip of the handle 1, and the handle attachment part 42 of the pressing fixation part 4 may be attached to the tip of the handle 1 in a pressing state in which both ends 3A, 3B of the cleaning body 3, which are in a butted state, are pressed and fixed from the outside against the cleaning support main body 21. In this case, the cleaning support main body 21 and the handle attachment part 22 of the cleaning support part 2 constitute part of the handle 1.

[0051] (3) In the above embodiment, the cleaning element 3 is attached to the cleaning support body 21 by wrapping it around in a single ring shape with both end faces 3a, 3b in the longitudinal direction butted against each other, but the wrapping structure is not limited to this. For example, the cleaning element 3 may be attached to the cleaning support body 21 by wrapping it around in a single ring shape with a gap provided between both end faces 3a, 3b in the longitudinal direction.

[0052] (4) In the above embodiment, both end portions 3A, 3B of the cleaning body 3 are pressed and fixed from the outside to the cleaning support body 21 by the pressing and fixing part 4, but this pressing structure is not limited to this. For example, when both end faces 3a, 3b of the cleaning body 3 are bonded to each other, or when the other end portion of the cleaning body 3 is bonded or engaged to the cleaning support body 21, only one end portion of the cleaning body 3 may be pressed and fixed to the cleaning support body 21 by the pressing and fixing part 4.
