In the cleaning tools including the toilet bowl cleaning tool and the toilet brush described above, a rod-shaped handle or a curved rod portion extends from each of the cleaning portion and the brush portion. Therefore, the portion from the cleaning portion for cleaning the object to the grip portion to be gripped is a rod-shaped portion extending long in a rod shape, and the distance from the cleaning portion to the grip portion is long, which makes it difficult to handle and reduces the efficiency of cleaning work. Sometimes. When the portion from the cleaning portion to the grip portion is a rod-shaped portion, the grip portion may not be able to move the cleaning portion well, and it may be difficult for the cleaning portion to follow a fine portion. Further, in the cleaning tool described above, since the rod-shaped portion is difficult to hold, cleaning may be performed by holding the root portion of the rod-shaped portion. In this case, the rod-shaped portion swings during cleaning, so that the rod-shaped portion may collide with another portion, and the cleaning tool may be damaged. Therefore, there is a demand for a cleaning tool that is easy to handle and can efficiently perform cleaning work.

The cleaning tool according to one embodiment of the present disclosure is a cleaning tool that cleans an object by contacting the object, and has a cleaning unit that contacts the object to clean the object and a grip portion that extends from the cleaning unit.

Hereinafter, embodiments of the cleaning tool according to the present disclosure will be described with reference to the drawings. In the description of the drawings, the same or corresponding elements are designated by the same reference numerals, and duplicate description will be omitted as appropriate. In addition, the drawings may be partially simplified or exaggerated, and the dimensions, angles, etc. are not limited to those described in the drawings.

The cleaning tool according to the present embodiment cleans the object to be cleaned and removes dirt and the like adhering to the object. The "object" in the present disclosure refers to an object to be cleaned, for example, an object around water including a toilet, a washroom, a bathroom and a kitchen, and tableware, cooking utensils, machines and structures. Etc., various things are included.

"Cleaning" indicates cleaning the object. "Washing" indicates that dirt is removed in the process of cleaning, and "cleaning part" indicates a part or member to be cleaned. "Cleaning" means, for example, rubbing the cleaning part against the object to scrape off the dirt on the object, removing the dirt with water or detergent, and polishing and removing the deposits such as rust. Includes. The cleaning tool according to the present embodiment includes a cleaning portion and a grip portion extending from the cleaning portion. "Gripping" means holding by hand, and "grip portion" means a part or member held by hand.

FIG. 1 shows an exemplary cleaning tool 1 according to an embodiment. As shown in FIG. 1, the cleaning tool 1 includes a cleaning unit 10 that comes into contact with an object to clean the object, and a grip portion 20 that extends from the cleaning unit 10 and is gripped by hand. .. The cleaning tool 1 is, for example, a toilet brush used for cleaning the toilet, which is used to polish the toilet bowl and clean the toilet bowl.

The cleaning tool 1 is, for example, a commercial toilet brush used by a building cleaner, and scrapes off dirt adhering to the toilet bowl by bringing the cleaning unit 10 into direct contact with the toilet bowl. Specifically, the grip portion 20 is gripped, the cleaning portion 10 is applied to the toilet bowl, and the cleaning portion 10 scrapes off dirt to perform cleaning. However, the cleaning tool 1 may be used for purposes other than the toilet brush.

FIG. 2 is a side view schematically showing the cleaning tool 1. As shown in FIGS. 1 and 2, the cleaning portion 10 is connected to the grip portion 20 and extends in the direction D1 intersecting the grip portion 20. As an example, the angle formed by the root portion of the grip portion 20 and the cleaning portion 10 may be a right angle. The cleaning portion 10 includes a base portion 11 extending from the grip portion 20 in the direction D1 intersecting the grip portion 20, and an inclined portion 12 inclined from the end portion of the base portion 11 in the direction D1.

The base portion 11 is a cleaning portion between the first surface 11b from which the grip portion 20 extends, the second surface 11c facing the opposite side of the first surface 11b, and the first surface 11b and the second surface 11c. It has a first curved surface 11d that is curved so as to project outward from the 10. The grip portion 20 extends from the first surface 11b. For example, each of the first surface 11b and the second surface 11c is a flat surface, and the first surface 11b and the second surface 11c extend in parallel with each other.

For example, when the grip portion extends from the first curved surface 11d in parallel with the base portion 11 (along the direction D1), it becomes difficult to hit the first curved surface 11d against the object, so that the first It can be difficult to use the curved surface 11d as the cleaning portion of the object. On the other hand, in the cleaning tool 1 according to the present embodiment, the grip portion 20 extends from the first surface 11b. Therefore, in the cleaning tool 1, the grip portion 20 extending from the first surface 11b can be gripped and the second surface 11c and the first curved surface 11d can be applied to the object, so that the second surface 11c and the second surface 11c The first curved surface 11d can be used as the cleaning portion of the object.

That is, by holding the grip portion 20 by hand and twisting the wrist while rubbing the object with the second surface 11c and the first curved surface 11d, it is possible to efficiently clean the object. Further, since the grip portion 20 extends from the first surface 11b, the pressing force of the base portion 11 against the object can be strengthened, so that the cleaning portion 10 can more effectively clean the object. Is possible.

The inclined portion 12 is inclined obliquely from one end of the direction D1 of the base portion 11, and for example, the grip portion 20 extends from the other end side of the direction D1 of the base portion 11. The inclined portion 12 is inclined toward the grip portion 20 from one end of the base portion 11 (obliquely upward when the grip portion 20 is located above the base portion 11), and projects obliquely toward the grip portion 20 side. By providing the inclined portion 12 protruding toward the grip portion 20 in this way, it is possible to insert the inclined portion 12 into a narrow portion such as the back of the edge of the toilet bowl and efficiently clean the narrow portion.

The inclined portion 12 is cleaned between the third surface 12b continuous with the first surface 11b, the fourth surface 12c continuous with the second surface 11c, and the third surface 12b and the fourth surface 12c. It has a second curved surface 12d that is curved so as to project to the outside of the portion 10. As an example, each of the third surface 12b and the fourth surface 12c is a flat surface, and the third surface 12b and the fourth surface 12c extend in parallel with each other.

The third surface 12b, the fourth surface 12c, and the second curved surface 12d are all portions that can be applied to the object, and can be used as cleaning portions of the object. As described above, in the cleaning tool 1, at least the second surface 11c, the first curved surface 11d, the third surface 12b, the fourth surface 12c, and the second curved surface 12d are used as cleaning portions of the object. Therefore, a large area of the cleaned portion can be secured. Therefore, while holding the grip portion 20 by hand and twisting the wrist, the second surface 11c, the first curved surface 11d, the third surface 12b, the fourth surface 12c, and the second curved surface are applied to all parts of the object. Since 12d can be applied, cleaning can be performed efficiently and reliably.

The grip portion 20 has, for example, a grip portion 21 gripped by a hand H (see FIG. 5 or FIG. 6) and a connecting portion 22 that connects the cleaning portion 10 and the grip portion 21. As an example, the connecting portion 22 extends at a right angle from the first surface 11b of the cleaning portion 10, and the grip portion 21 extends obliquely with respect to the cleaning portion 10 in the direction D2 away from the cleaning portion 10.

The grip portion 20 is sized to be covered with the human hand H. For example, when the grip portion 21 is gripped by the hand H, the grip portion 21 does not protrude from the hand H. As described above, since the grip portion 20 is sized to fit in the hand H, the hand H can be moved to freely move the cleaning portion 10 in all directions, and the handleability of the cleaning tool 1 is improved. ..

The grip portion 21 and the connecting portion 22 have, for example, a rod shape having a length enough to be covered with the hand H. The grip portion 21 is arranged in the direction D2 between the fifth surface 21b facing the opposite side of the cleaning portion 10, the sixth surface 21c facing the cleaning portion 10, and the fifth surface 21b and the sixth surface 21c. It has 21 g of an extending seventh surface. Further, the grip portion 21 has, for example, a tip portion 21d forming an end portion of the grip portion 21, and a hole portion 21f penetrating the fifth surface 21b and the sixth surface 21c.

The fifth surface 21b may be a flat surface or a curved surface that curves outward of the grip portion 21. The seventh surface 21g is provided on both sides of the fifth surface 21b in the width direction (direction orthogonal to the paper surface of FIG. 2), for example. The seventh surface 21g may be a flat surface or a curved surface that curves outward of the grip portion 21.

The sixth surface 21c is curved so as to project to the outside of the grip portion 21, for example. Since the sixth surface 21c is curved outward in this way, the grip portion 21 has a shape that is easy to grip. The hole portion 21f is a hole for hooking the cleaning tool 1 on a locking tool such as a hook, and as an example, the hole portion 21f extends in the direction D2 in which the grip portion 21 extends.

The tip portion 21d has an eighth surface 21h continuous with the seventh surface 21g and a ninth surface 21j located on the tip end side of the grip portion 21 of the hole portion 21f. The eighth surface 21h and the ninth surface 21j are, for example, curved surfaces that project to the outside of the grip portion 21. As described above, the grip portion 21 has a fifth surface 21b, a sixth surface 21c, a seventh surface 21g, an eighth surface 21h, and a ninth surface 21j, but the boundary portion between these surfaces is Both have obtuse angles.

That is, the fifth surface 21b, the sixth surface 21c, the seventh surface 21g, the eighth surface 21h and the ninth surface 21j are connected to each other via an obtuse angle portion, for example, the grip portion 21. Does not have sharp or right-angled corners. Therefore, since the grip portion 21 as a whole has a rounded shape, the grip portion 21 has a shape that is easy to hold.

The connecting portion 22 has a columnar shape protruding from the cleaning portion 10. The connecting portion 22 is the opposite side of the tenth surface 22b continuous with the sixth surface 21c, the eleventh surface 22c continuous with the seventh surface 21g, and the fifth surface 21b of the eleventh surface 22c. It has a twelfth surface 22d located at, and a finger contact surface 22f located between the twelfth surface 22d and the fifth surface 21b.

The tenth surface 22b, the eleventh surface 22c, and the twelfth surface 22d are, for example, flat surfaces or curved surfaces that project to the outside of the connecting portion 22. The finger contact surface 22f extends diagonally with respect to the twelfth surface 22d, and the inclination angle of the finger contact surface 22f with respect to the direction D1 is larger than the inclination angle of the grip portion 21 (direction D2) with respect to the direction D1.

The finger contact surface 22f is a surface on which the finger H1 of the hand H that grips the grip portion 20 is placed (see FIG. 5 or FIG. 6). The finger contact surface 22f is a flat surface or a curved surface recessed inside the grip portion 20. As described above, since the finger contact surface 22f is a flat surface or a curved surface recessed inward, the finger H1 can be easily placed on the finger contact surface 22f, so that the grip portion 20 can be more easily gripped. ..

The finger contact surface 22f is provided between the cleaning portion 10 and the grip portion 21, and for example, the grip portion 20 is gripped by placing a finger H1 (for example, a thumb or index finger) on the finger contact surface 22f and gripping the grip portion 21. Is shaped to be easier to grip. The grip portion 20 does not have to have the connecting portion 22, and for example, the grip portion 21 may extend directly from the cleaning portion 10.

The grip portion 20 is made of resin, for example. The material of the grip portion 20 may be a flexible material, and in this case, the grip portion 20 can be deformed. As an example, the material of the grip portion 20 is polypropylene resin (PP) or epoxy resin. The grip portion 20 may be a rigid body, and the material of the grip portion 20 can be changed as appropriate.

Assuming that the length of the grip portion 21 in the grip portion 20 is the length L1 and the length of the connecting portion 22 (the height of the connecting portion 22 with respect to the cleaning portion 10) is the length L2, for example, the length L1 is 150 mm or less. is there. Further, the upper limit of the length L1 may be 120 mm, 110 mm, 100 mm, 90 mm, 80 mm or 70 mm. The lower limit of the length L1 may be, for example, 30 mm, 40 mm, 50 mm, 60 mm or 70 mm. As an example, the length L1 is 80 mm or more and 110 mm or less.

The length L2 is, for example, 15 mm or more. In this case, since the length L2 of the connecting portion 22 can be set to one finger or more, the finger H1 can be easily placed on the connecting portion 22. Further, the lower limit of the length L2 may be 5 mm, 10 mm or 20 mm. The upper limit of the length L2 is, for example, 50 mm and may be 40 mm, 30 mm or 20 mm. As an example, the length L2 is 15 mm or more and 50 mm or less.

As an example, the connecting portion 22 extends at a right angle from the cleaning portion 10, and the angle θ1 formed by the connecting portion 22 and the grip portion 21 (direction D2) is, for example, 30 ° or more and 300 ° or less. That is, the inclination direction of the grip portion 21 with respect to the base portion 11 (direction D1) may be a direction other than the direction away from the base portion 11 and the inclined portion 12, and is in a direction approaching at least one of the base portion 11 and the inclined portion 12. There may be. The lower limit of the angle θ1 may be 45 °, 60 °, 75 °, 90 ° or 120 °. The upper limit of the angle θ1 may be 270 °, 240 °, 225 °, 180 °, 150 ° or 120 °. As an example, the angle θ1 is 90 ° or more and 270 ° or less.

The inclination angle θ2 of the inclined portion 12 with respect to the base portion 11 is, for example, 10 ° or more and 90 ° or less, but is not particularly limited. The upper limit of the tilt angle θ2 may be 80 °, 75 °, 70 °, 60 ° or 50 °. The lower limit of the tilt angle θ2 may be 10 °, 30 °, 45 ° or 50 °.

Assuming that the minimum height of the cleaning tool 1 is the minimum height L3, for example, the minimum height L3 is 70 mm or more. Here, the "minimum height of the cleaning tool" is the minimum height of the cleaning tool in the side view (side view of the cleaning tool when the cleaning tool is arranged so that the grip portion is located above the cleaning portion). The values are shown, for example, a straight line A1 extending along the direction D2 in which the grip portion 21 extends from the second curved surface 12d of the inclined portion 12, and a direction in which the grip portion 21 extends from the first curved surface 11d of the base portion 11. It is the distance from the straight line A2 extending along D2.

The lower limit of the minimum height L3 may be 80 mm, 90 mm, 100 mm or 110 mm. The upper limit of the minimum height L3 may be 200 mm, 180 mm, 150 mm, 120 mm or 110 mm. As an example, the minimum height L3 is 70 mm or more and 150 mm or less.

The cleaning portion 10 includes a skeleton portion 13 extending along the base portion 11 and the inclined portion 12, and a deformable covering portion 14 covering the skeleton portion 13. FIG. 3 is an exemplary side view showing the skeleton S of the cleaning tool 1 including the skeleton portion 13 and the grip portion 20. As shown in FIGS. 1 to 3, the skeleton portion 13 includes a first bone portion 13b constituting the base portion 11 and a second bone portion 13c (tip portion) constituting the inclined portion 12. .. The first bone portion 13b has a plate shape extending in the direction D1, and the second bone portion 13c is a tip portion protruding from one end of the direction D1 of the first bone portion 13b toward the grip portion 20.

The covering portion 14 covers the entire skeleton portion 13, for example. In this case, since the deformable covering portion 14 covers the entire skeleton portion 13, it is possible to prevent the skeleton portion 13 from being damaged. The covering portion 14 includes a sponge 14b that covers the skeleton portion 13 and a non-woven fabric 14c that covers the sponge 14b. The materials of the sponge 14b and the non-woven fabric 14c are different from each other. For example, the covering portion 14 has a double structure made of two different materials. The sponge 14b is located inside the non-woven fabric 14c and is made of a material softer than the non-woven fabric 14c.

The sponge 14b is deformable. For example, the sponge 14b is an elastic foam, and as an example, urethane foam (urethane sponge). The non-woven fabric 14c may contain, for example, abrasive particles (granular abrasives). Further, the nonwoven fabric 14c has a sponge 14b wrapped around the base portion 11 and the inclined portion 12, and the sponge 14b has an exposed surface 14d facing the width direction D3 of the nonwoven fabric 14c. The covering portion 14 configured as described above is wound around the first bone portion 13b and the second bone portion 13c.

The covering portion 14 has a connecting portion 14f (see FIGS. 11 and 12) for connecting the pair of covering portions 14 to each other on the first surface 11b on which the grip portion 20 extends. The covering portion 14 has, for example, an elongated shape extending in the direction D1 before being wound around the skeleton portion 13 (the first bone portion 13b and the second bone portion 13c). The connecting portion 14f is formed by connecting one end 14g and the other end 14h of the direction D1 of the covering portion 14 when wound around the skeleton portion 13 along the direction D1 to each other.

FIG. 4 is an exemplary plan view showing the skeleton S of the cleaning tool 1 including the skeleton portion 13 and the grip portion 20. As shown in FIGS. 3 and 4, the first bone portion 13b extends from the grip portion 20 in the direction D1 intersecting the grip portion 20, and the second bone portion 13c is in the direction of the first bone portion 13b. It is tilted from the end of D1. The first bone portion 13b has a first plate-shaped portion 13d extending so as to surround the grip portion 20 at the end (lower end) of the grip portion 20, and a first plate-shaped portion 13d extending in the direction D1 from the first plate-shaped portion 13d. It has 2 plate-shaped portions 13f.

When viewed from the grip portion 20 side (in a plan view), for example, the second plate-shaped portion 13f extends linearly in the direction D1, and the first plate-shaped portion 13d is in the direction of the second plate-shaped portion 13f. It has a shape that extends from the end of D1. That is, the width of the first plate-shaped portion 13d becomes wider as the distance from the second plate-shaped portion 13f increases.

The first plate-shaped portion 13d includes a pair of first side edges 13g extending diagonally from the second plate-shaped portion 13f to both sides of the second plate-shaped portion 13f in the width direction D4, and a pair of first plates. It has a second side 13h extending in the width direction D4 on the opposite side of the side 13g from the second plate-shaped portion 13f. Each first side 13g extends along the outer shape of the grip portion 20, and is curved so as to bulge outward, for example. The second side 13h extends linearly along, for example, the width direction D4.

The thickness of the first plate-shaped portion 13d and the second plate-shaped portion 13f may be uniform, or may become thicker as it approaches the grip portion 20. The second plate-shaped portion 13f has a pair of third sides 13j extending along the direction D1, for example, a pair of third sides 13j extending in parallel with each other. The width W1 of the second plate-shaped portion 13f is not particularly limited, but may be constant.

The second bone portion 13c has a plate shape continuous with the second plate-shaped portion 13f, and obliquely protrudes toward the grip portion 20 from the end portion of the second plate-shaped portion 13f in the direction D1. The thickness of the second bone portion 13c may be reduced, for example, as the distance from the first bone portion 13b (toward the tip of the second bone portion 13c) increases.

For example, the width of the second bone portion 13c may be the same as the width W1 of the second plate-shaped portion 13f. That is, the width W1 of the portion of the skeleton portion 13 extending from the grip portion 20 in the direction D1 may be constant, and may be, for example, 5 mm or more and 30 mm or less. As an example, the width W1 may be 10 mm or more and 25 mm or less.

The width W1 may be half or less of the width W2 (see FIG. 1) of the covering portion 14. Further, the width W1 may be 40% or less, 30% or less, 25% or less, or 10% or less of the width W2. As an example, the width W2 of the covering portion 14 is 50 mm or more and 70 mm or less. Further, the width W3 of the grip portion 21 of the grip portion 20 is, for example, the width W1 or more and the width W2 or less. The width W3 is, for example, 15 mm or more and 35 mm or less.

The manufacturing method of the cleaning tool 1 configured as described above will be described. For example, the skeleton S of the cleaning tool 1 including the grip portion 20 and the skeleton portion 13 is manufactured by resin molding (step of preparing the skeleton of the cleaning tool). After preparing the skeleton S in this way, a strip-shaped sponge 14b and a strip-shaped non-woven fabric 14c are prepared. Then, a hole is made in the sponge 14b and the non-woven fabric 14c, the grip portion 20 is passed through the hole, and the sponge 14b and the non-woven fabric 14c are wound around the skeleton portion 13 along the direction D1. Then, by fixing the sponge 14b to the skeleton portion 13 with glue or the like (step of winding and fixing the sponge), the production of the cleaning tool 1 is completed.

Subsequently, the operation and effect of the cleaning tool 1 according to the present embodiment will be described. As described above, in the cleaning tool 1, when the cleaning unit 10 comes into contact with the object, dirt on the object is removed and cleaning is performed. As shown in FIGS. 5 and 6, the grip portion 20 is a portion to be gripped when the cleaning tool 1 is held by the hand H, and extends obliquely with respect to the base portion 11 of the cleaning portion 10. Further, the grip portion 20 is sized so that it can be covered by the user's hand H. Therefore, since the distance from the base portion 11 to the tip of the grip portion 20 can be shortened, the handleability of the cleaning portion 10 can be improved.

That is, since the grip portion 20 can be held by the hand H and the cleaning portion 10 can be freely moved, the cleaning tool 1 can be easily handled, and the efficiency of the cleaning work can be improved. Since the grip portion 20 extending from the base portion 11 has a size that can be covered by the hand H, the cleaning portion 10 can be moved well and the cleaning portion 10 can be turned in a small direction. The cleaning unit 10 can be made to follow. For example, the thumb (finger H1) is placed on the finger contact surface 22f to grip the grip portion 21, or the index finger (finger H1) is placed on the finger contact surface 22f to grip the grip portion 21 to realize various gripping methods. Therefore, the handleability of the cleaning tool 1 is further improved.

Further, since the grip portion 20 has a size covered by the hand H, it is possible to prevent the grip portion 20 and the like from colliding with other portions, so that the cleaning tool 1 can be made less likely to be damaged. Further, the cleaning portion 10 has a base portion 11 and an inclined portion 12 that is inclined with respect to the base portion 11, and the inclined portion 12 is provided at an end portion of the base portion 11 opposite to the grip portion 20. Therefore, since the inclined portion 12 can be inserted into the narrow portion of the object to be cleaned to clean the narrow portion, the narrow portion can be efficiently cleaned by inserting the inclined portion 12.

The minimum height L3 of the cleaning portion 10 and the grip portion 20 may be 70 mm or more. In this case, since the minimum height L3 of the cleaning portion 10 and the grip portion 20 is 70 mm or more, for example, cleaning the drain pipe T1 of the toilet bowl T, which is the object of cleaning, as shown in FIGS. 7 and 8. The invasion of the tool 1 can be suppressed. That is, the minimum height L3 of the cleaning portion 10 and the grip portion 20 can be set to be equal to or larger than the diameter of the drain pipe T1. Therefore, since the cleaning tool 1 can be prevented from entering the drain pipe T1, even if the cleaning tool 1 accidentally falls into the drain pipe T1 of the toilet bowl T during cleaning, the cleaning tool 1 is deep inside the drain pipe T1. It is possible to more reliably avoid a situation such as clogging of 1.

The grip portion 20 has a grip portion 21 extending obliquely with respect to the base portion 11 of the cleaning portion 10, and the length L1 of the grip portion 21 may be 150 mm or less. In this case, since the length L1 of the grip portion 21 extending obliquely with respect to the base portion 11 is 150 mm or less, the grip portion 21 can be reliably accommodated in the hand H that grips the grip portion 20. Therefore, it is possible to prevent the grip portion 20 from colliding with other portions during cleaning, and it is possible to improve the handleability of the cleaning tool 1.

The cleaning portion 10 includes a skeleton portion 13 and a deformable covering portion 14, and the skeleton portion 13 has a tip portion (second bone portion 13c) inclined with respect to the base portion 11 and is inclined. The portion 12 includes a covering portion 14 that covers the inclined tip portion (second bone portion 13c), and the width W1 of the skeleton portion 13 may be half or less of the width W2 of the covering portion 14. In this case, the width W1 of the skeleton portion 13 is set to be half or less of the width W2 of the covering portion 14 that covers and deforms the skeleton portion 13. Therefore, since the width W1 of the skeleton portion 13 is narrower than the width W2 of the covering portion 14, it is possible to grip the covering portion 14 and easily squeeze the water accumulated in the covering portion 14.

Further, when the width W1 of the skeleton portion 13 is less than half of the width W2 of the covering portion 14, the volume of the covering portion 14 that can be deformed with respect to the skeleton portion 13 can be increased, so that the cleaning portion 10 is easily deformed. can do. As a result, the cleaning unit 10 can be flexibly followed when the cleaning unit 10 is inserted into a narrow portion, so that cleaning can be performed more efficiently and reliably.

The covering portion 14 may include a sponge 14b covering the skeleton portion 13 and a non-woven fabric 14c covering the sponge 14b. In this case, since the sponge 14b is covered with the non-woven fabric 14c in the covering portion 14, the covering portion 14 can be easily assembled and the cushioning property of the covering portion 14 can be improved.

An example of the covering portion 14 provided with the strip-shaped sponge 14b and the strip-shaped non-woven fabric 14c, and the winding of the covering portion 14 around the skeleton portion 13 will be described in detail. As shown in FIG. 9, the covering portion 14 has an elongated shape extending in the direction D1. The covering portion 14 has a pair of end faces 14j extending in the direction D1 between one end 14g and the other end 14h of the covering portion 14 and facing the width direction D3 of the covering portion 14. For example, each end face 14j is a flat surface. As an example, one end 14g of the covering portion 14 has a pair of end faces 14p located at both ends in the width direction D3 and a convex portion 14k protruding in the direction D1 between the pair of end faces 14p. The other end 14h of the covering portion 14 has a pair of end faces 14q located at both ends in the width direction D3 and a recess 14m recessed in the direction D1 between the pair of end faces 14q.

The covering portion 14 has a hole portion 14r through which the skeleton portion 13 (for example, the first bone portion 13b and the second bone portion 13c) is inserted. The hole portion 14r penetrates, for example, the plate-shaped covering portion 14 in the plate thickness direction. The hole portion 14r is formed, for example, on one end 14g side of the covering portion 14. As an example, the hole portion 14r is formed at a position adjacent to the convex portion 14k formed at one end 14g of the covering portion 14. For example, the hole portion 14r has an upper base 14s located on the convex portion 14k side, a lower base 14t located closer to the center of the covering portion 14 in the direction D1 than the upper base 14s, and the upper base 14s and the lower base 14t. It has a trapezoidal shape with a pair of legs 14v to be connected. However, the position, shape and size of the hole 14r are not limited to the above examples and can be changed as appropriate.

An example of a method of winding the covering portion 14 around the skeleton portion 13 will be described. First, as shown in FIGS. 9 and 10, the second bone portion 13c and the first bone portion 13b are inserted into the hole portion 14r of the covering portion 14, and the skeleton portion 13 is pushed into the hole portion 14r to form the hole portion. The 14r is pushed open so that the skeleton portion 13 is inserted into the hole portion 14r. At this time, the skeleton portion 13 is inserted into the hole portion 14r so that the skeleton portion 13 projects from one end 14 g of the covering portion 14 in the direction D1.

Next, as shown in FIGS. 11 and 12, the covering portion 14 is lifted, one end 14g of the covering portion 14 and the other end 14h of the covering portion 14 are passed under the skeleton portion 13, and the sponge 14b of the covering portion 14 is passed. The adhesive is applied to the portion 14w of the sponge 14b facing upward with a part of the sponge facing upward. At this time, for example, the adhesive is also applied to the end face 14p, the convex portion 14k, the end face 14q and the concave portion 14m. After that, the other end 14h is lifted to cover the skeleton portion 13 with the sponge 14b, and the concave portion 14m at the other end 14h is fitted into the convex portion 14k at one end 14g from above. In this state, by pressing the other end 14h with a jig or the like (or a finger) for a certain period of time, the sponge 14b is adhered to the skeleton portion 13 to form the connecting portion 14f, and the winding of the covering portion 14 is completed. The constant time for pressing the other end 14h with a jig or the like is, for example, 30 seconds or more and 24 hours or less, and as an example, it may be 1 minute or more and 2 minutes or less.

As described above, as shown in FIGS. 2 and 12, the covering portion 14 is a connecting portion 14f for connecting a pair of covering portions 14 (one end 14g and the other end 14h) to the first surface 11b on which the grip portion 20 extends. May have. In this case, the connecting portion 14f is formed on the first surface 11b, so that the connecting portion 14f is cleaned as described above (for example, the second surface 11c, the first curved surface 11d, the third surface 12b, and the third surface 12b. It can be formed at a location other than the surface 12c of No. 4 and the second curved surface 12d). Therefore, since the connecting portion 14f is formed at a position away from the cleaning portion of the cleaning portion 10, it is possible to reduce the concern that the strength of the cleaning portion of the cleaning portion 10 is lowered and to prolong the life of the cleaning portion.

By the way, in the covering portion 14, there is a possibility that a minute gap 14x extending in the width direction D3 and being exposed on each end surface 14j is formed in the connecting portion 14f. When the exposed gap 14x is formed on the end surface 14j, there is a concern that dirt or the like may enter the inside of the covering portion 14 from the gap 14x. Further, the gap 14x exposed on the end surface 14j may expand as the cleaning tool 1 is used, and if the gap 14x expands, the skeleton portion 13 may be exposed from the gap 14x and the skeleton portion 13 may damage the toilet bowl or the like. There is. On the other hand, in the covering portion 24 described later, it is possible to suppress the occurrence of the above-mentioned gap 14x.

As shown in FIG. 13, the covering portion 24 has an elongated shape extending in the direction D1. The covering portion 24 extends in the direction D1 between the one end 24g in the direction D1, the other end 24h located on the opposite side of the one end 24g in the direction D1, the one end 24g and the other end 24h, and the width direction D3 of the covering portion 24. It has a pair of facing end faces 24j. As described above, the partial configuration of the covering portion 24 is similar to the partial configuration of the covering portion 14. Therefore, in the following description, the description of the portion overlapping with the description of the covering portion 14 will be omitted as appropriate, and the configuration of the covering portion 24 which is the same as the configuration of the covering portion 14 will be designated by the same reference numerals as the configuration of the covering portion 14. I will explain.

One end 24g of the covering portion 24 has a pair of inclined surfaces 24b located on both end sides in the width direction D3 and a facing surface 24c extending in the width direction D3 between the pair of inclined surfaces 24b. For example, one end 24g has a trapezoidal shape with the facing surface 24c as the upper base and each inclined surface 24b as the leg. The pair of inclined surfaces 24b and facing surfaces 24c are formed so as to surround, for example, the hole portion 14r (connecting portion 22 of the grip portion 20).

Each inclined surface 24b is inclined and extends from each end surface 24j in a direction protruding in the direction D1, for example. In this case, the angle θ3 formed by the inclined surface 24b and the end surface 24j is larger than 90 ° and less than 180 ° (obtuse angle). The angle θ3 may be, for example, 120 ° or more and 150 ° or less, or 130 ° or more and 140 ° or less. Further, the angle θ3 on one side of the width direction D3 and the angle θ3 on the other side in the width direction D3 may be different from each other.

Each inclined surface 24b extends along the hole portion 14r so as to face the hole portion 14r, and as an example, is inclined to the same side as the leg 14v of the hole portion 14r with respect to the direction D1. For example, each inclined surface 24b is a flat surface. The facing surface 24c faces the hole 14r along the direction D1, for example. That is, the facing surface 24c forms an end portion in the direction D1 of the covering portion 24, and extends along, for example, the upper bottom 14s of the hole portion 14r. As an example, the facing surface 24c may extend parallel to the width direction D3 (or parallel to the upper base 14s).

The other end 24h of the covering portion 24 has a pair of inclined surfaces 24d located at both ends in the width direction D3 and a facing surface 24f extending in the width direction D3 between the pair of inclined surfaces 24d. For example, the other end 24h has a trapezoidal recess having an facing surface 24f as an upper base and each inclined surface 24d as a leg. Each inclined surface 24d is inclined from each end surface 24j in the direction in which the covering portion 24 is recessed in the direction D1. In this case, the angle θ4 formed by the inclined surface 24d and the end surface 24j is larger than 0 ° and less than 90 ° (acute angle). The angle θ4 may be, for example, 30 ° or more and 60 ° or less, or 40 ° or more and 50 ° or less. Further, the angle θ4 on one side of the width direction D3 and the angle θ4 on the other side in the width direction D3 may be different from each other.

The method of winding the covering portion 24 around the skeleton portion 13 is the same as that of the covering portion 14. However, in the state shown in FIGS. 11 and 12, in the case of the covering portion 14, the concave portion 14m is fitted into the convex portion 14k from above, whereas in the case of the covering portion 24, the concave other end 24h is inserted. It can be fitted into the convex one end 24 g from above and can also be fitted from the side (from direction D1). Therefore, the covering portion 24 having the trapezoidal unevenness at one end 24g and the other end 24h connects the other end 24h to the one end 24g more than the covering portion 14 having the rectangular unevenness at one end 14g and the other end 14h. It has the advantage that it can be easily performed and the connection portion is easily formed.

As described above, the cleaning tool 1 may include a covering portion 24 having trapezoidal irregularities instead of the covering portion 14. In this case, the covering portion 24 has a pair of inclined surfaces 24b and 24d extending obliquely with respect to the end face 24j from the end face 24j facing the width direction D3 of the covering portion 24. In the covering portion 24, the other ends 24h can be firmly connected to the one end 24g of the covering portion 24 by combining the inclined surfaces 24b and 24d and the facing surfaces 24c and 24f. Further, in the case of the covering portion 24 having the pair of inclined surfaces 24b and 24d, as compared with the case of the covering portion not having the pair of inclined surfaces 24b and 24d (only the plane extending in the width direction D3), the one end is 24 g. Since the contact area of the other end 24h can be increased, the connection strength of the connecting portion can be increased.

Further, in the case of a covering portion in which one end and the other end are connected only by a plane extending in the width direction D3, a crevice may be formed in parallel with the width direction D3 of the covering portion. Therefore, as shown in FIG. Therefore, there is a concern that the crevice will widen and the skeleton will be exposed when the covering is squeezed. On the other hand, in the case of the covering portion 24 having the inclined surfaces 24b and 24d extending obliquely with respect to the width direction D3, the inclined surfaces 24b and 24d are in close contact with each other along the direction D1 even if the covering portion 24 is narrowed down. It is possible to prevent the formation of crevices. Therefore, it is possible to prevent dirt and the like from entering the inside of the covering portion 24, so that the cleaning tool 1 can be made more hygienic.

The inclined surfaces 24b and 24d may be inclined in a direction closer to the grip portion 20 (hole portion 14r) toward the end surfaces 24j (both ends of the width direction D3). In this case, when the covering portion 24 is squeezed, the inclined surfaces 24b and 24d are easily deformed along the grip portion 20, so that the above-mentioned crevices can be further less likely to occur and damage to the sponge 14b can be suppressed. it can.

The covering portion 24 may have facing surfaces 24c and 24f extending along the grip portion 20 (hole portion 14r) and facing the grip portion 20 between the pair of inclined surfaces 24b and 24d. In this case, since the covering portion 24 has the facing surfaces 24c and 24f, even when a slight deviation in the width direction D3 occurs when the other end 24h is connected to one end 24g, the deviation is absorbed. be able to. Therefore, since the connection of the other end 24h to the one end 24g can be performed more efficiently, the covering portion 24 can be wound around the skeleton portion 13 more efficiently.

The embodiment of the cleaning tool according to the present disclosure has been described above. However, the present disclosure is not limited to the above-described embodiment, and may be modified or applied to other things without changing the gist described in each claim. That is, the shape, size, material, number, and arrangement of each part of the cleaning tool can be appropriately changed without departing from the above gist.

For example, in the above-described embodiment, the covering portion 24 having trapezoidal irregularities at one end 24 g and the other end 24 h, respectively, has been described. However, the shape of the connecting portion at one end and the other end of the covering portion can be changed as appropriate. For example, as shown in FIG. 15A, the curved convex portion 34b is provided at one end 34g in the direction D1, the curved concave portion 34c is provided at the other end 34h of the direction D1, and the curved concave portion 34c is provided at the curved convex portion 34b. It may be the covering portion 34 to be connected.

In this case, the portions on both ends of the curved convex portion 34b and the curved concave portion 34c in the width direction D3 are inclined with respect to the end surface 24j. Therefore, similarly to the covering portion 24 described above, the contact area between one end 34g and the other end 34h can be increased, cracks can be less likely to occur when the covering portion 34 is squeezed, and the covering portion 34 with respect to the skeleton portion 13 Can be wound efficiently. The shapes of the curved convex portion 34b and the curved concave portion 34c when the covering portion 34 is viewed from the plate thickness direction may be arcuate or parabolic, and can be changed as appropriate.

As shown in FIG. 15B, a plurality of peaks 44b are provided at one end 44g in the direction D1, a plurality of valleys 44f are provided at the other end 44h of the direction D1, and each of the plurality of peaks 44b. It may be a covering portion 44 to which each of the plurality of valley portions 44f is connected. For example, each mountain portion 44b has a first inclined surface 44c inclined in a direction protruding from the end surface 24j in the direction D1, and a second inclined surface 44c inclined in a direction recessed from the protruding end in the direction D1 of the first inclined surface 44c. Includes an inclined surface 44d. Each valley portion 44f has, for example, a third inclined surface 44j that inclines from the end surface 24j in the recessed direction in the direction D1, and a fourth inclined surface that inclines in the direction protruding from the most recessed portion of the third inclined surface 44j in the direction D1. Includes surface 44k.

In the case of the covering portion 44, the portions on both ends (for example, the first inclined surface 44c and the third inclined surface 44j) of the mountain portion 44b and the valley portion 44f in the width direction D3 are inclined with respect to the end surface 24j. Therefore, the covering portion 44 can obtain the same effects as those of the covering portion 24 and the covering portion 34 described above. In the example of FIG. 15B, three peaks 44b are formed at one end 44g, and three valleys 44f are formed at the other end 44h. However, the number, shape, size and arrangement of the peaks 44b and the valleys 44f can be changed as appropriate.

As shown in FIG. 15 (c), one end 54g of the direction D1 has a pair of inclined surfaces 54b forming a mountain shape, and the other end 54h of the direction D1 has a pair of inclined surfaces 54c forming a valley shape. It may be a covering portion 54 in which a pair of inclined surfaces 54c forming a valley shape are connected to a pair of inclined surfaces 54b forming a mountain shape. For example, each inclined surface 54b is inclined with respect to the direction D1 to the same side as the leg 14v of the hole 14r.

Each inclined surface 54b extends along the hole portion 14r so as to face the hole portion 14r, similarly to the inclined surface 24b of the covering portion 24 described above. Therefore, the same effect as that of the covering portion 24 can be obtained from the covering portion 54. That is, in the covering portion 54, since the inclined surfaces 54b and 54c are easily deformed along the grip portion 20 when squeezed, it is possible to prevent the above-mentioned crevices from occurring and to avoid damage to the sponge 14b.

As described above, various examples of the covering portion have been described as shown in FIGS. 15A to 15C. However, the shapes of one end and the other end of the direction D1 of the covering portion can be further changed with respect to the examples of FIGS. 15 (a) to 15 (c). Further, FIG. 12 shows an example in which the connecting portion 14f (gap 14x) extends in the plate thickness direction of the covering portion 14. However, the connecting portion that connects one end and the other end of the covering portion to each other may extend in a direction that is inclined from the plate thickness direction of the covering portion. That is, the inclined surface of the connecting portion may be three-dimensionally inclined. Also in this case, since the gap formed in the covering portion can be made inconspicuous, the same effect as described above can be obtained.

Further, in the above-described embodiment, the covering portion 14 including the sponge 14b and the non-woven fabric 14c has been described. However, the covering portion that covers the skeleton portion 13 may include, for example, only the non-woven fabric 14c or only the sponge 14b, and the material of the covering portion and the type of the material can be appropriately changed. Further, in the above-described embodiment, an example in which the covering portion 14 is fixed to the skeleton portion 13 has been described. However, the covering portion may be detachable from the skeleton portion. Further, the cleaning portion may be detachable from the grip portion.

Further, in the above-described embodiment, the cleaning tool 1 which is a toilet brush used for cleaning the toilet has been exemplified. However, the cleaning tool according to the present disclosure can be applied to objects other than toilets. That is, the cleaning tool according to the present disclosure may be used for cleaning a washroom, a bathroom, a kitchen, tableware, cooking utensils, a machine, a building, a structure, or the like. It is possible to apply the cleaning tool according to the present disclosure to these objects to be cleaned.
