Description

  The present invention relates to a drain outlet cover for covering a drain outlet provided on a washing floor of a bathroom.

  The drain outlet provided on the washing floor in the bathroom is normally covered with a drain outlet lid (see, for example, Patent Documents 1 and 2). About the drainage lid, it may be required to make the material metal from reasons, such as appearance appearance for producing a high-class feeling.

However, if the drain cover is entirely made of a metal plate, there is a concern about the safety of the operator's body when the drain cover is dropped during cleaning of the drain cover. If the drain cover is entirely a metal plate, for example, if it is intended to have a strength that does not easily cause bending deformation when the bather gets on top, the thickness must be relatively large. , The overall weight will increase. For this reason, for example, when cleaning the drain cover, damage may occur if the drain cover is dropped on the foot of the cleaner, and more particularly when the edge of the metal plate hits the foot. It is.
Therefore, as a means for solving such a problem, the present inventors have first conceived that a metal plate is laminated on a resin body. However, if the metal plate is simply placed on the resin body, misalignment between the metal plate and the resin body occurs, and water enters the gap formed between the metal plate and the resin body (for example, metal If the plate is warped or otherwise distorted, a gap is formed between the metal plate and the resin body). For this reason, there exists a possibility that the situation where this clearance gap part becomes unsanitary may generate | occur | produce.

A resin body that supports the metal plate and has an upper convex portion provided on the upper surface portion that enters at least one through hole of the plurality of through holes. The body is provided with a drainage hole that is opposed to the lower surface of the metal plate, and that allows the water flowing into the inside from the upper opening to flow out of the resin body. It is characterized by being.

According to such a configuration, the following effects can be obtained.
First, since the metal plate has a structure laminated on the upper side of the resin body, a design that brings out a high-class feeling using the metal plate can be obtained, but the disadvantage that the metal plate alone easily bends and deforms easily. It is supplemented by the resin body, the thickness of the metal plate can be reduced, and the overall weight can be reduced and the strength can be improved. Therefore, there is an advantage that damage caused by dropping on the foot during handling can be reduced. About the edge part of a metal plate, it is possible to cover with a resin body, and it can prevent appropriately that the edge part of a metal plate hits a handler's leg etc. directly.
Secondly, since the upward convex portion provided on the upper surface portion of the resin body enters the through hole of the metal plate, it is possible to position the resin body and the metal plate in the horizontal direction. .
Third, water may flow into the through hole of the metal plate, but such water can be discharged to the outside of the resin body through a drain hole provided in the resin body. . Therefore, water that has flowed into the through holes of the metal plate, and further water that has entered the gap between the metal plate and the resin body from the through holes is prevented from staying in those portions, It becomes possible to appropriately prevent the portion from becoming unsanitary.

  In the present invention, preferably, the upper end portion of the upward convex portion protrudes upward from the upper surface portion of the metal plate and functions as a non-slip convex portion.

  In the present invention, preferably, the resin body includes a main body portion on which the upper surface portion is mounted and the metal plate is placed, and a leg portion protruding downward from a position near the outer peripheral edge of the main body portion. The drainage hole is a first drainage hole that is provided at a position near the center of the main body so as to avoid the formation of the leg, and penetrates in the vertical thickness direction of the main body. It has.

  According to such a structure, most of the water that has flowed into the through hole out of the water flowing on the metal plate can be discharged downward from the first drain hole. Therefore, it is possible to prevent a large amount of water from collecting on the metal plate, in the through hole, and in the gap between the metal plate and the resin body.

  In the present invention, preferably, the metal plate is provided with a downward projecting portion, and the drainage hole is a hole portion for positioning the metal plate by inserting the downward projecting portion. Including a second drainage hole, and the hole portion is configured to form a flow path through which water can flow between an inner surface of the hole portion and an outer surface of the downward projecting portion. Has been.

  According to such a configuration, the metal plate can be positioned more accurately with respect to the resin body based on the structure in which the downward projecting portion of the metal plate is inserted into the hole of the resin body. In addition, since the second drainage hole is provided using the hole, the configuration is reasonable.

  In the present invention, preferably, water that has entered between the resin body and the metal plate is guided to the upper opening portion of the drainage hole on the upper surface portion of the resin body or the lower surface portion of the metal plate. As possible, a drain groove for promoting drainage connected to the upper opening of the drain hole is provided.

  According to such a configuration, it is more preferable in preventing a large amount of water from remaining between the resin body and the metal plate.

  In the present invention, it is preferable that a magnet exhibiting a magnetic force for holding the metal plate on the upper surface portion of the resin body is embedded in the resin body.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  FIG. 1 shows a wash basin waterproofing pan P and a drainage lid A used as components of a bathroom such as a unit bath.

  The washing place waterproofing pan P is entirely made of resin and forms the washing place floor 1. The washing place waterproof pan P can be a bathtub-integrated type (not shown), but in FIG. 1, it is a separate bathtub type, and is located next to the wash place waterproof pan P (next to the one side edge 90 in FIG. 1). ) Is installed in the bathtub. In the washing floor 1 near the one side edge portion 90, for example, a concave portion 4 having a substantially rectangular shape in a plan view and a drain port 3 located at the lower back of the concave portion 4 are provided. A drain pipe (not shown) is connected to the lower side of the drain port 3 via a drain trap. The concave portion 4 is a portion for fitting and installing the drainage lid A. The drain port 3 is covered with the drain port lid A by fitting the drain port lid A into the recessed portion 4.

The drainage lid A is configured by combining the metal plate 2 and the resin body 5.
As clearly shown in FIG. 2, the metal plate 2 is a flat plate having a substantially rectangular shape in plan view, and is made of a material excellent in corrosion resistance (for example, made of stainless steel). The metal plate 2 is provided with a plurality of through-holes 20 penetrating in the vertical thickness direction, arranged in a matrix form at appropriate intervals vertically and horizontally. Downward protruding portions 21 are provided on the lower surface portions of the four corner portions of the metal plate 2. As will be described later, the downward projecting portion 21 is a portion for connecting the metal plate 2 to the resin body 5. For example, an upper portion of a stainless steel cylindrical member is welded to the lower surface portion of the metal plate 2. Is provided. The downward projecting portion 21 is provided with a screw hole 21a having a lower opening.

The resin body 5 serves as a pedestal for supporting the metal plate 2 and is made of, for example, a fiber reinforced resin. The resin body 5 includes a main body portion 50 on which the metal plate 2 is placed, and leg portions 51 that protrude downward from a position near the outer peripheral edge of the main body portion 50. The resin body 5 is provided with a first drainage hole 52A, a plurality of second drainage holes 52B, a plurality of upward convex portions 53, and an upward convex edge portion 54.

  The upward convex edge portion 54 has an upward rib shape provided in a rectangular frame shape in plan view along the outer peripheral edge of the main body portion 50. The metal plate 2 is fitted inside the upward convex edge portion 54 and placed on the upper surface portion 5 a of the resin body 5. The plurality of upward convex portions 53 are provided on the upper surface portion 5a so as to be arranged in a matrix with vertical and horizontal intervals at the periphery of the first drainage hole 52A, and the metal plate 2 is provided on the upper surface portion 5a. When placed, it fits into the plurality of through holes 20 from below. In this inserted state, as shown in FIG. 3, the upper end portion of the upward convex portion 53 protrudes upward with an appropriate dimension La (for example, sufficient several mm to several mm) than the upper surface portion of the metal plate 2. To do. Accordingly, the upward convex portion 53 serves as a non-slip convex portion of the upper surface portion of the drainage lid A. As shown in the enlarged view of the main part of the figure, a minute gap C1 is formed between the inner peripheral surface of the through hole 20 and the outer peripheral surface of the upward convex portion 53, and this gap C1 (in the through hole 20). There is a risk of water entering the water. This water may further flow into the minute gap C2 between the lower surface portion of the metal plate 2 and the upper surface portion 5a of the resin body 5. Since the warp and other distortions are usually present on the lower surface portion of the metal plate 2 and the upper surface portion 5a of the resin body 5, the above-described gap C2 is generated, and water flows into the gap C2.

  In FIG. 2, the first drainage hole 52 </ b> A is formed as a through hole located at a substantially central portion of the main body 50. In the present embodiment, the first drainage hole 52A is circular, but can be formed in other shapes such as an ellipse or a rectangle. As clearly shown in FIGS. 4 and 5, the upper opening of the first drainage hole 52 </ b> A is formed on the lower surface of the metal plate 2 in a state where the metal plate 2 is placed on the resin body 5. It directly faces and communicates with the plurality of through holes 20. For this reason, when water flows into the through-hole 20 communicating with the first drainage hole 52A, the water passes through the first drainage hole 52A as it is and is discharged downward.

  In FIG. 6, the plurality of second drain holes 52 </ b> B are configured using holes 52 a into which the plurality of downward projecting portions 21 of the metal plate 2 are fitted. More specifically, the resin body 5 is provided with a plurality of hole portions 52a and 52b into which the downward projecting portion 21 is inserted in a vertically connected manner. The upper hole portion 52a is provided so that the upper opening is located at or near the four corners of the upper surface portion 5a. On the other hand, a resin or rubber plug 6 is fitted and attached to the lower opening of the lower hole 52b. The plug 6 protrudes downward from the lower surface portion of the leg portion 51 and is a portion in contact with the concave portion 4 where the drain port lid A is installed. The downward projecting portion 21 of the metal plate 2 is fixed using a screw body 7 such as a screw in a state of being fitted into the holes 52a and 52b. This fixing is performed, for example, by screwing the screw body 7 into the screw hole 21a of the downward projecting portion 21 so that the spring washer 71 and the flat washer 72 are brought into contact with the upper wall surface of the hole portion 52b. With such a fixing structure, the metal plate 2 and the resin body 5 are fixedly connected.

  The hole 52a has a flow path 52c for allowing the water to flow into the hole 52b when water enters the hole 52a from the upper gap C2. The flow path 52c is configured by, for example, providing a key groove-shaped recess in the hole 52a. On the other hand, a notch 60 is formed in the plug 6, and the water that has flowed into the hole 52 b after passing through the flow path 52 c can be discharged from the notch 60 to the outside of the resin body 5. It is possible. The second drain hole 52B is configured by combining the holes 52a and 52b and the notch 60.

  Next, the operation of the drainage lid A will be described.

Since the drainage lid A has a structure in which the metal plate 2 is laminated on the upper side of the resin body 5, a design that brings out a high-class feeling using the metallic luster on the surface of the metal plate 2 can be obtained. Further, since the resin body 5 supports a wide area of the metal plate 2 so as not to easily bend and deform even when the metal plate 2 is stepped on, as the metal plate 2, It is possible to use one having a relatively small thickness. Therefore, it is possible to reduce the overall weight as compared with the case where the drain cover is made of only a metal plate. As a result, it is possible to relieve damage in the case of being dropped on the foot during handling. Since the edge part of the metal plate 2 is covered with the upward convex edge part 54, when the drain outlet lid A is dropped, the edge part of the metal plate 2 hitting the operator's foot is also preferably avoided.
Since the upper end portion of the upward convex portion 53 of the resin body 5 protrudes upward from the upper surface portion of the metal plate 2 and functions as a non-slip convex portion, a bather or the like slips on the metal plate 2. It is also possible to suitably suppress the occurrence of

  There is a possibility that water flows into the through hole 20 of the metal plate 2 or the gap C2 between the metal plate 2 and the resin body 5. However, as shown in FIG. 4, the water that has flowed into the through hole 20 located above the first drainage hole 52A passes through the first drainage hole 52A and is discharged downward as it is. On the other hand, as described with reference to FIG. 6, the water flowing into the gap C <b> 2 can be discharged outside the resin body 5 using the second drainage hole 52 </ b> B. Therefore, it is possible to prevent a large amount of water from staying in the through-hole 20 and the gap C2, and to prevent these portions from becoming unsanitary. Since the second drainage hole 52B is formed using the holes 52a and 52b for fixing the metal plate 2 to the resin body 5, the configuration is rational and suppresses the complexity of the structure. Advantages that can be obtained are also obtained. If the screw body 7 is loosened, it is possible to remove the metal plate 2 from the resin body 5, and therefore, it is possible to easily and accurately perform the cleaning operation.

  7 to 10 show other embodiments of the present invention. In these drawings, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment.

In the drain outlet lid Aa shown in FIG. 7, the upper surface portion 5a of the resin body 5 is provided with a plurality of drainage promoting concave grooves 57 connected in a lattice pattern. The concave grooves 57 are connected to each other in series, and are also connected to the upper opening of the drain hole 52B (second drain hole 52B).
According to such a configuration, when water enters between the metal plate 2 and the upper surface portion 5 a of the resin body 5, the water is positively guided to the drain hole 52 </ b> B, and the metal plate 2 and the resin body 5. It is possible to more appropriately prevent a large amount of water from remaining in between. In the present embodiment, a drainage hole corresponding to the first drainage hole 52A of the above embodiment is not provided, and it enters between the metal plate 2 and the resin body 5 as compared with the above embodiment. Although there is a high possibility that the amount of water to be increased, the drainage performance utilizing the drainage holes 52B can be enhanced by adopting the configuration of the present embodiment.

  In the drain outlet lid Ab shown in FIG. 8, unlike the drain outlet lid Ab shown in FIG. 7, the resin body 5 is provided with a first drain hole 52A. The groove 57 for promoting drainage is connected to the first drainage hole 52A in addition to the second drainage hole 52B, and the water that has entered the gap C2 between the metal plate 2 and the resin body 5 is recessed. An effect of passing through the groove 57 and being guided to the first drainage hole 52A and discharged to the outside can also be expected.

In the drain outlet cover Ac shown in FIG. 9, additional concave grooves 58 connected in a lattice shape are further formed in each base part 5 b surrounded by a plurality of concave grooves 57 for promoting drainage of the resin body 5. .
According to such a configuration, the phenomenon that the water on the pedestal 5 b flows through the additional concave groove 58 and flows down into the concave groove 57 is promoted. Therefore, it is more preferable in preventing water from remaining between the resin body 5 and the metal plate 2 (not shown in the figure).
In addition, it can also be set as the structure provided in the lower surface part of the metal plate 2 instead of providing in the resin body 5 about the ditch | groove 57 for drainage promotion and the additional ditch | groove 58 of above-described embodiment. Even with such a configuration, it is possible to obtain the same effect as described above.

In the drain outlet lid Ad shown in FIG. 10, a magnet 8 is embedded in the resin body 5. In the figure, the entire magnet 8 is embedded in the resin body 5, but the upper surface portion of the magnet 8 may be embedded in a state where the upper surface portion 5 a of the resin body 5 is exposed. The metal plate 2 is held on the upper surface portion of the resin body 5 by the magnetic force of the magnet 8. When the material of the metal plate 2 is, for example, JIS-SUS400, the metal plate 2 can be appropriately magnetically adsorbed.
In this embodiment, the metal plate 2 and the resin body 5 can be positioned and fixed without using a screw body such as a screw, and the metal plate 2 can be easily attached to and detached from the resin body 5. be able to.
