Description

Technical Field

[0001] The present invention relates to a cover member for a drain opening that improves the design by covering the drain opening of a tank body.

Background Art

[0002] In order to treat the drainage generated inside a tank body such as a bathtub or a washbowl, a drain opening is provided on the bottom surface or side surface of the tank body, and a structure for discharging the drainage to the downstream side through a piping member from the drain opening is widely known. However, dirt such as scale and dust easily adheres to the inside of the piping member, and the design deteriorates if it is visible to the user. Also, in some cases, a drain opening is formed in the tank body by attaching a member such as a drain opening body to the opening provided in the tank body in a watertight manner. However, if the above-mentioned scale, dust, etc. adhere to the joint between the tank body and the member forming the drain opening, the design also deteriorates. For this reason, a method of covering the drain opening with a cover member to prevent deterioration of the design is known.

[0003] The cover member described in Patent Document 1 includes a disk-shaped cover body, a cylindrical portion extending downward from the cover body, and legs provided on the side surface of the cylindrical portion. The diameter of the cover body is configured to be larger than the diameter of the circle formed by the joint between the member forming the drain opening and the tank body. When the cover member is disposed at the drain opening, the cover body covers the drain opening of the tank body and its surroundings, thereby covering the inside of the drain opening of the tank body and the joint between the tank body and the member forming the drain opening, and making it impossible for the user to visually recognize the scale, dust, etc. adhering to the drain opening and the joint portion, thereby improving the design. Further, when the cylindrical portion is inserted into the drain opening provided on the bottom surface of the tank body, the lower end of the leg abuts against the bottom surface of the tank body, and a gap space is formed between the tank body, the drain opening, and the cover body. When drainage occurs inside the tank body, the drainage flows into the drain opening from the gap space and is discharged to the downstream side through the piping member.

[0004] In this way, the cover member described in Patent Document 1 improves the design by covering the drain opening, and enables drainage from the drain opening by forming a gap space.

Problems to be Solved by the Invention

[0006] In the cover member for the drain opening described in Patent Document 1, the lower end of the leg portion abuts against the bottom surface of the tank body, thereby forming a gap space for drainage between the cover body and the tank body or the drain opening. For this reason, when attaching the cover member to the drain opening, the bottom surface of the tank body is easily scratched by the leg portion. In addition, if an impact is applied by, for example, placing hands or feet on the upper surface of the cover member of the drain opening or placing an article such as a pail thereon, the impact is directly transmitted from the leg portion to the member forming the tank body or the drain opening, and a large scratch may be caused. Further, since the cover member of the drain opening protrudes from the bottom surface of the tank body to form a gap space, it is easily impacted when an article is placed in the tank body, and there are many opportunities for the tank body to be scratched. The present invention has been invented in view of the above problems, and provides a cover member for a drain opening that forms a gap space between the tank body or the drain opening and the cover body of the cover member for the drain opening, while making it difficult for an impact to be transmitted to the tank body and preventing scratches or the like on the inner surface of the tank body.

Advantages of the Invention

[0012] In the present invention, in a cover member of a drain opening which is an opening provided in a tank body, by locking a rib piece provided on a cover body to an edge portion of the opening of the drain opening, the cover member can be arranged at the drain opening of the tank body. At this time, the portion where the cover member of the drain opening abuts on the tank body is only the edge portion of the opening of the drain opening. Therefore, even if an impact is applied to the cover body and a scratch occurs on the tank body side, the scratch will only slightly occur at the portion where the rib piece abuts on the edge portion of the opening of the drain opening. Further, the scratch generated on the edge portion of the opening of the drain opening is at a position that is difficult to visually recognize compared to the scratch generated on the bottom surface of the tank body, and is easily covered by the cover member. Further, in the present invention, by providing an inclined surface on the rib piece, it can be used without trouble even when the diameter of the edge portion of the opening of the drain opening of the tank body is different. Further, by the rib piece abutting on the inner surface of the drain opening, the cover member of the drain opening can be stably arranged without tilting with respect to the drain opening. Further, since the rib piece has a flat portion and the flat portion abuts on the edge portion of the opening of the drain opening, the cover member of the drain opening can be stably arranged without tilting with respect to the drain opening. Further, by providing a strainer member on the cover member of the drain opening, hairs, dust, etc. during drainage can be collected.

Embodiments for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the following description is for facilitating understanding of the embodiments, and the invention is not limited to this understanding.

[0015] As shown in FIG. 1, the tank body 1 is a concave washbowl with an open upper part. A drain port 2 is formed in the bottom surface 11, and an overflow drain port 4 is formed in the side surface 12. Further, the tank body 1 is placed on a cabinet C, and piping members are housed inside the cabinet C.

[0016] The drain port main body 3 is hollow and cylindrical, forming a drain flow path inside, having a cylindrical tube part 31 and a flange part 32 in the shape of a flange. By being attached to an opening drilled in the bottom surface 11 of the tank body 1, a drain port 2 for discharging the hot and cold water in the tank body 1 is formed. In this embodiment, the corner formed by the inner side surface of the tube part 31 and the upper surface of the flange part 32 of the drain port 2 is the edge part 21 of the opening of the drain port 2. The tube part 31 is cylindrical with a male screw formed on the outer side surface, and is screwed with a nut 5 on the back surface of the tank body 1. An opening for the drain from the overflow drain port 4 to merge is formed on the side surface of the tube part 31. The flange part 32 is in the shape of a flange formed outward from the upper end of the tube part 31, and in a state where the drain port main body 3 is attached to the tank body 1, it abuts against the periphery of the opening drilled in the bottom surface 11 via a packing.

[0017] The drain port main body 3 has a piping member such as a drain trap connected to the downstream side, and discharges the drain flowing in from the drain port 2 and the overflow drain port 4 to the downstream side.

[0018] As shown in FIGS. 2 to 5, the cover member 6 is composed of a cover body 7, rib pieces 73 provided on the cover body 7, a retaining plate member 8, and a covering member 9, and is a member that is disposed at the drain port 2 to cover and conceal the inside of the drain port 2 and the drain port body 3 so as not to be visible.

[0019] The cover body 7 is in the shape of a circular plate and is configured to have a diameter larger than that of the flange portion 32 of the drain port body 3. On the side of the drain port 2, that is, on the lower side in FIG. 2, it is provided with a shaft portion 71, an engaging portion 72, and rib pieces 73. Further, a covering member 9 made of a metal material is attached to the upper surface of the cover body 7. In FIG. 2, a part of the shaft portion 71 and the covering member 9 that cannot be visually recognized by the rib pieces 73 are shown by broken lines. The shaft portion 71 is cylindrical and extends from the center of the cover body 7 toward the drain port 2 side, and an engaging portion 72 is formed at the lower end. The engaging portion 72 is a groove recessed over the entire circumference of the shaft portion 71 in the vicinity of the lower end of the shaft portion 71, and is detachably engaged with the engaged portion 82 of the retaining plate member 8 in a state where the cover member 6 is assembled. As shown in FIG. 4 in a bottom view, the rib pieces 73 are ribs radially formed at four locations every 90 degrees from the center of the cover body 7. As shown in FIG. 3, in a state where the cover member 6 is disposed at the drain port 2, by engaging with the edge portion 21 of the opening of the drain port 2, a gap space S through which drainage passes is formed between the cover body 7 and the drain port 2. Further, the rib pieces 73 have inclined surfaces 74 that extend toward the center of the cover body 7 as they approach the ends. The inclined surface 74 is provided with a bent portion 74a in the middle. The side closer to the cover body 7 than the bent portion 74a is substantially arc-shaped, but a straight portion 74b is formed on the lower end side than the bent portion 74a. When the cover member 6 is disposed at the drain port 2, the straight portion 74b contacts the inner surface of the drain port 2 below the edge portion 21 to position the cover member 6. Further, as shown in FIG. 5, the outer surface of the inclined surface 74 located on the radially outer side of the cover body 7 has a flat portion 74c that contacts the edge portion 21 of the opening of the drain port 2 in a cross-sectional view.

[0020] The strainer member 8 is a member that is disposed inside the drain opening 2 and collects hair, dust, and the like in the drained water, and is detachably attached to the cover body 7. Further, the strainer member 8 includes a bearing portion 81, an engaged portion 82, an annular portion 83, and a collecting portion 84. The bearing portion 81 is a hollow cylindrical shape formed at the center of the strainer member 8, and the engaged portion 82 is formed on the inner surface. The engaged portion 82 is a convex portion formed inward from the inner surface of the bearing portion 81, and engages with the engaging portion 72 of the cover body 7. The annular portion 83 is an annular shape having substantially the same outer diameter as the inner surface of the drain opening main body 3. The collecting portion 84 is a net-like shape that collects hair, dust, and the like in the drained water, and is formed so as to connect the outer surface of the bearing portion 81 and the inner surface of the annular portion 83.

[0021] In the state where the cover member 6 in the present invention is disposed at the drain opening 2, the cover body 7 covers the joints between the drain opening 2, the flange portion 32, and the tank body 1, so that the design property of the washbowl can be improved. Further, by locking the rib piece 73 of the cover member 6 to the edge portion 21 of the opening of the drain opening 2, a gap space S is formed between the drain opening 2 and the cover body 7, and the drained water passes through the gap space S and can be discharged from the drain opening 2. Furthermore, the cover member 6 is configured such that the rib piece 73 is locked not to the bottom surface 11 of the tank body 1 or the upper surface of the flange portion 32 but to the edge portion 21 of the opening of the drain opening 2. As a result, since the contact area with the tank body 1 can be reduced, when an impact is applied to the cover member 6, it is difficult to cause a large scratch on the inner surface of the tank body 1 or the drain opening main body 3. Further, by the linear portion 74b abutting on the inner surface of the drain opening 2 and the flat portion 74c of the rib piece 73 abutting on the edge portion 21 of the opening of the drain opening 2, the cover member 6 can be stably arranged without tilting with respect to the drain opening 2.

[0022] Further, in the cover member 6 of the present invention, the rib piece 73 has an inclined surface 74 that faces the center of the cover body 7 as it moves away from the cover body 7. When the inclined surface 74 abuts against the edge portion 21, the rib piece 73 is configured to be locked to the edge portion 21. As a result, as described below, it is possible to arrange the cover member 6 even when the diameter of the drain port 2 is different. When the cover member 6 is arranged at drain ports 2 having different diameters, a washer member 8 adapted to the inner diameter of the drain port 2 is appropriately attached to the cover body 7.

[0023] FIG. 6 shows a tank body 1 in which a small-diameter drain port 2 is formed, and a cover member 6 attached to the tank body 1. At this time, the cover member 6 is positioned above the position when it is attached to the drain port 2 described in FIG. 2, and the rib piece 73 is arranged at the drain port 2 by locking the straight portion 74b to the edge portion 21. On the other hand, as shown in FIG. 7, when the cover member 6 is attached to the tank body 1 in which a large-diameter drain port 2 is formed, the cover member 6 can be arranged at the drain port 2 by locking to the edge portion 21 at a substantially arc-shaped portion formed above the bent portion 74a.

[0024] The embodiments of the present invention are as described above. However, the present invention is not limited to the shapes of the embodiments, and appropriate changes may be made without departing from the gist of the invention. For example, in the above embodiment, the tank body 1 was a washbowl, but it may be a bathtub, a sink, or other tank bodies. Further, in the above embodiment, the drain port 2 is formed by attaching the drain port main body 3 to the tank body 1, and the edge portion 21 is formed on the drain port main body 3. However, as shown in FIG. 8, the edge portion 21 may be formed on the tank body 1. Even in this case, the cover member 6 is locked to the edge portion 21 of the opening of the drain port 2 by the rib piece 73, rather than the bottom surface 11 of the tank body 1, thereby preventing a large scratch from occurring on the tank body 1. Further, in the above embodiment, the cover member 6 is arranged at the drain port 2 formed on the bottom surface 11 of the tank body 1, but it may be arranged at the overflow drain port 4 formed on the side surface 12 of the tank body 1.
