  The present invention has been conceived under the circumstances as described above, and an object of the present invention is to provide a drainage cap that can reduce the risk of being accidentally dropped during handling.

  In order to solve the above problems, the present invention takes the following technical means.

  The drainage lid provided by the present invention is a drainage lid for covering the drainage port, the metal plate having a plurality of openings penetrating in the vertical thickness direction, and the metal plate laminated on the lower surface side of the metal plate. And a resin body having a plurality of fitting portions that are in contact with the edge on the lower surface side of the plate and fit into the plurality of openings.

According to such a configuration, the following effects can be obtained.
That is, since each fitting part of the resin body is locked to the opening of the metal plate, it is responsible for fixing the metal plate and the resin body, and the laminated structure of the metal plate and the resin body is integrated. The Therefore, according to the present invention, a metal design surface excellent in design and cleaning properties is formed by the upper surface of the metal plate exposed when the drain port is installed, and the drain port lid has a laminated structure of the metal plate and the resin body. The required strength can be sufficiently secured. As a result, the metal design surface is suitable for designing relatively lightly. The light drainage lid is less likely to be accidentally dropped during handling by a person who performs drainage cleaning or the like, so that an effect of reducing the risk of being accidentally dropped can also be obtained. In addition, according to the present invention, since the resin body that forms a laminated structure integrally with the metal plate is in contact with the edge on the lower surface side of the metal plate, the edge shape of the edge is not exposed. For this reason, even if the drain lid is accidentally dropped, the edge of the lower side of the metal plate can be prevented from damaging the operator's body, and the danger caused by the operator accidentally dropping it Suitable for reducing

In the present invention, preferably, at least one of the plurality of openings is an upwardly-opening opening, and at least one of the plurality of fitting parts is upward of the upward-opening opening. It is set as the fitting part fitted in the said opening part so that an inclined surface may be contacted.
According to such a configuration, it is suitable for enhancing the locking state of the fitting portion extending from the resin body with respect to the opening of the metal plate, and the metal plate and the resin body are more firmly fixed, It is possible to appropriately prevent the metal plate from rattling or lifting.

In the present invention, preferably, the metal plate has a downward annular convex portion in which at least one lower opening peripheral edge of the plurality of openings protrudes downward and is engaged with the resin body.
According to such a configuration, an effect of further strengthening the fixation between the metal plate and the resin body can be obtained based on the action of the downward annular convex portion engaging with the resin body.

In this invention, Preferably, the said resin body has the surrounding frame part which covers the outer peripheral side surface of the said metal plate.
According to such a configuration, in addition to fixing the metal plate and the resin body more firmly, it is more suitable for reducing the above-described danger caused by the operator accidentally dropping. That is, in the above configuration, the peripheral frame portion of the resin body covers the outer peripheral side surface of the metal plate, and is in contact with the edge on the upper surface side in addition to the edge on the lower surface side of the metal plate. The edge shape is not exposed. Therefore, when the drain cover is accidentally dropped, the edges of the upper surface side and the lower surface side of the metal plate are preferably prevented from damaging the handler's body. The peripheral frame portion also has a function of preventing the operator from being scratched by the metal edge at the edge of the metal plate.

In this invention, Preferably, the said surrounding frame part has the 1st overlap part which overlapped with the outer-periphery edge part of the upper surface of the said metal plate.
According to such a configuration, the first overlapping portion contributes to fixing the metal plate and the resin body, and also exhibits an anti-slip effect on the upper surface of the metal plate. The metal plate is particularly slippery when its upper surface is wet. For example, with regard to a drain lid attached to the drain on the bathroom floor, the bather may fall over by sliding his feet on the drain lid. Although it is necessary to prevent this, the first overlapping portion also exhibits an anti-slip effect capable of preventing such a situation.

In the present invention, preferably, at least one of the plurality of fitting portions protrudes above the metal plate and is formed with a second overlapping portion that overlaps a part of the upper surface of the metal plate. It is said that.
According to such a configuration, the second overlapping portion contributes to fixing the metal plate and the resin body, and also exhibits an anti-slip effect on the upper surface of the metal plate.

In the present invention, preferably, the resin body has a dark color.
According to such a configuration, it is possible to make the design of the metal design surface in the drainage palate stand out and to make it difficult to produce a sense of incongruity in the combination of the resin body and the metal plate. When using the drain lid on the floor drain outlet of a bathroom, for example, the dark resin body is easily visible as if it is the gap between the floor and the drain lid lid, or part of it. It is easy to harmonize the entire palate with the floor of the bathroom without a sense of incompatibility.

In the present invention, preferably, the metal plate and the resin body are continuously opened in the thickness direction, and an opening through which liquid can flow from the upper surface of the metal plate to the lower side of the resin body. Is provided.
According to such a configuration, it is possible to provide the drainage lid with drainage so that a large amount of liquid such as hot water does not accumulate on the drainage lid.

In this invention, Preferably, the additional metal plate laminated | stacked on the lower surface side of the said resin body is further provided.
According to such a configuration, the lower surface side of the resin body is hardly contaminated, and the drainage cover cleaning operation and the like can be facilitated. The resin body is more likely to be stained than the metal plate, and the lower surface side of the resin body is easily contaminated only by the metal plate being laminated on the upper surface of the resin body. Since it is covered with the additional metal plate, the above-mentioned problems can be solved and the drain cover can be made more hygienic. Further, the presence of the additional metal plate can further increase the overall strength while reducing the thickness of the drain cap.

In the present invention, preferably, a plurality of additional openings penetrating the additional metal plate in the thickness direction are provided at or near the four corners of the additional metal plate, and the resin body includes the plurality of the resin bodies. It has a portion that fits into the additional opening and protrudes downward from the additional metal plate, and this portion is a leg for supporting the drain port lid.

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

  A drain outlet lid X1 shown in FIGS. 1 to 3 is for covering a drain outlet recessed in a bathroom floor or the like, and includes a metal plate 10 and a resin body 20.

  The metal plate 10 is a flat plate having a substantially rectangular shape in plan view, and has a plurality of openings 14 and 15. The thickness of the metal plate 10 is, for example, 0.3 to 10 mm, and the material thereof is, for example, stainless steel such as SUS304 or copper.

  The upper surface 11 of the metal plate 10 is a surface exposed to the outside in a state where the drain port lid X1 is mounted on the drain port, and is the main part of the exposed design surface of the drain port lid X1. The plurality of openings 14 and 15 penetrate in the vertical thickness direction of the metal plate 10, but a fitting portion 22 described later enters the opening 14. The opening 15 is vacant so that liquid can flow therethrough.

  The resin body 20 has a main body portion 21, a plurality of fitting portions 22, a peripheral frame portion 23, and a pair of convex portions 24, and is laminated on the lower surface 12 side of the metal plate 10.

  The body portion 21 of the resin body 20 is formed in a size and shape capable of supporting the metal plate 10 and has notches 21a and 21b and a plurality of openings 21c. Each opening 21c communicates with the opening 15 of the metal plate 10 as shown well in FIG. These openings 15 and 21c form openings (drainage holes) through which the liquid can flow through the metal plate 10 and the resin body 20 in series. 3B, the main body 21 is in contact with the edge 12a on the lower surface 12 of the metal plate 10, and extends in the horizontal direction in the figure beyond the edge 12a.

  The plurality of fitting portions 22 are fitted into the plurality of openings 14 of the metal plate 10 and locked to the metal plate 10. As clearly shown in FIG. 3B, the front end 22a of each fitting portion 22 and the upper surface 11 of the metal plate 10 are flush with each other. The peripheral frame portion 23 is erected so as to surround the metal plate 10 on the main body portion 21, and covers the outer peripheral side surface 13 of the metal plate 10 as well as shown in FIG. 3B. In contact with the edge 11a of the upper surface 11 of the substrate. The tip 23a of the peripheral frame portion 23 and the upper surface 11 of the metal plate 10 are flush with each other. As shown in FIG. 1, the pair of convex portions 24 are provided on the same side as the notch 21 a in the main body portion 21 with the notch 21 a interposed therebetween.

  The resin body 20 is made of, for example, a fiber reinforced resin. As the fiber reinforced resin, for example, a sheet composite material in which polypropylene is reinforced with continuous glass fibers can be used. The resin body 20 is colored in a dark color such as black or dark brown. For example, by using a resin material added with carbon black powder as the resin material of the resin body 20, the resin body 20 colored in black can be obtained.

The drainage lid X1 can be manufactured as follows.
First, a thermoplastic resin material reinforced with fiber and a metal plate 10 that are superposed in a predetermined orientation are subjected to heat softening treatment at a predetermined heating temperature and timing, and then a mold is used. Apply press molding. The mold used has an inner surface shape designed to mold the outer shape of the resin body 20 of the drainage lid X1. Therefore, in the press molding process, a part of the resin material enters and fills the opening 14 of the metal plate 10, while the main body 21 with the opening 21 c is formed and the opening 15 of the metal plate 10 is formed in the opening 15. The resin body 20 is molded so that the resin material does not enter. The portion filled in the opening portion 14 during the press molding process forms the fitting portion 22. Next, unnecessary portions are cut and removed from the resin material solidified after the press molding process, leaving the resin body 20 part. With such a stampable molding technique, the drainage lid X1 can be manufactured.

  Next, the usage example and effect | action of above-described drainage lid X1 are demonstrated.

  First, as shown in FIGS. 4 and 5, for example, the drain outlet lid X1 is used by being mounted on a drain outlet 31 recessed in the bathroom floor 30 or the like. The bathroom floor 30 has an overall inclined structure and an inclined structure of each part such that hot water on the bathroom floor 30 flows toward the drain port 31. The drain port 31 has a receiving port 31a having a structure capable of receiving the drain port lid X1 and supporting it from below. The drainage lid X1 has a design dimension such that the bathroom floor 30 and the upper surface of the drainage lid X1 are flush with each other when the drainage is installed, and there are horizontal gaps G and G ′ between the receptacle 31a. .

  The hot water that has flowed on the bathroom floor 30 toward the drain port 31 enters the gaps G and G ′ when reaching the drain port lid X1, passes through the notches 21a and 21b of the resin body 20 of the drain port lid X1, and then drains. Flows into 31. Alternatively, the hot water reaching the drain port lid X1 flows into the drain port 31 through the above-described openings 15 and 21c penetrating the metal plate 10 and the resin body 20. In this way, the hot water on the bathroom floor 30 is drained. Since the tip 23a of the peripheral frame portion 23 of the resin body 20 and the upper surface 11 of the metal plate 10 are flush with each other, the flow of hot water between the bathroom floor 30 and the drainage lid X1 is blocked by the peripheral frame portion 23. It is realized as smooth without any problems. Such a configuration is suitable for realizing good drainage.

  When the drain port lid X1 is taken out from the receiving port 31a of the drain port 31, it is easy to perform the take-out operation by hooking a finger on the notch 21a of the main body 21 of the resin body 20. In the drainage lid X1, the pair of convex portions 24 and the notches 21a in the resin body 20 are dimensionally designed so that a gap G ′ that allows a finger to be inserted between the receiving port 31a and the drainage lid X1 is secured. Yes.

  In the drain port lid X1 as described above, each fitting portion 22 of the resin body 20 is locked to the opening portion 14 of the metal plate 10 so as to fix the metal plate 10 and the resin body 20, and the metal plate 10. And the laminated structure of the resin body 20 are integrated. Therefore, according to the drain port lid X1, a laminated structure of the metal plate 10 and the resin body 20 while forming a metal design surface excellent in design and cleaning by the upper surface 11 of the metal plate 10 exposed when the drain port is installed. Therefore, the strength required for the drainage lid X1 can be ensured. Therefore, the drainage lid X1 is suitable for designing relatively lightly while having a metal design surface. The light drainage lid X1 is less likely to be accidentally dropped during handling by a person who performs drainage cleaning or the like, and is suitable for reducing the risk of being accidentally dropped.

  In the drainage lid X1, as clearly shown in FIG. 3B, the resin body 20 that forms a laminated structure integrally with the metal plate 10 is formed on the edge 12a of the lower surface 12 of the metal plate 10 on the upper surface 11 as well. It is also in contact with the edge 11a. Specifically, the main body portion 21 and the peripheral frame portion 23 of the resin body 20 both cover and cover the edge 12 a of the lower surface 12, the peripheral frame portion 23 contacts the edge 11 a of the upper surface 11, and the edge of the metal plate 10. A configuration in which 11a and 12a are not exposed as edges is realized. Therefore, even when the drainage lid X1 is accidentally dropped, it is possible to prevent the edges or the edges 11a and 12a of the metal plate 10 from damaging the operator's body.

  In addition, the drainage lid X1 can be efficiently manufactured by the stampable molding technique as described above. Where the metal plate 10 has a plurality of openings 14, the resin body 20 is formed of a resin material used for the press molding process and has a plurality of fitting portions 22 that fit into the openings 14 of the metal plate 10. . Each of the plurality of fitting portions 22 is locked to the opening 14 of the metal plate 10 and is responsible for fixing between the metal plate 10 and the resin body 20. The peripheral frame portion 23 of the resin body 20 that covers the outer peripheral side surface 13 of the metal plate 10 also contributes to fixing between the metal plate 10 and the resin body 20. Therefore, in the drainage lid X1, it is not necessary to fix between the metal plate 10 and the resin body 20 with an adhesive or the like. Therefore, the drain lid X1 can be efficiently manufactured by simultaneously molding the resin body 20 and simultaneously or simultaneously fixing the resin body 20 and the metal plate 10.

  Since the resin body 20 has a dark color such as black or dark brown, it is suitable for suppressing the influence on the design of the metal design surface of the drainage palate X1. The fitting portion 22 and the peripheral frame portion 23 that are dark colors such as black and dark brown easily harmonize the drainage pawl X1 with the bathroom floor 30 on which the drainage pawl X1 is used without any sense of incongruity. The dark-colored fitting portion 22 is easily visually recognized as if it were a through hole similar to the opening 15 and the opening 21c. The dark-colored peripheral frame portion 23 is easily visually recognized as if it is a part of the gaps G and G 'between the bathroom floor 30 and the drain lid X1.

  6 to 18 show another embodiment of the present invention. In these drawings, the same or similar elements as those of the previous embodiment are denoted by the same reference numerals as those of the previous embodiment, and redundant description is omitted.

It has the 1st overlap part 23b which overlapped with the part. Each fitting portion 22 </ b> A has a second overlapping portion 22 b that protrudes above the metal plate 10 and overlaps a part of the upper surface 11 of the metal plate 10. The second overlapping portion 22 b has a larger diameter than the opening 14.

  According to the present embodiment, the first and second overlapping portions 23b and 22b have a structure in which the upper surface 11 of the metal plate 10 is pressed, which contributes to fixing the metal plate 10 and the resin body 20A. This is suitable for preventing the metal plate 10 from being lifted. In addition, the metal surface is generally slippery particularly in a wet state, and the configuration in which the first and second overlapping portions 23b and 22b protrude above the metal plate 10 is an anti-slip effect on the upper surface 11 of the metal plate 10. The bather is less likely to slide his / her feet on the metal plate 10.

  In the drainage lid X3 shown in FIG. 8, a plurality of openings 14A provided in the metal plate 10A are spread upward from the lower surface 12 side to the upper surface 11 side of the metal plate 10A. The fitting portion 22B of the resin body 20B has a wedge shape corresponding to the opening portion 14A, and is fitted into the opening portion 14A so as to contact the upward inclined surface of the opening portion 14A.

  In the present embodiment, since the fitting portion 22B is locked to the opening portion 14A in a wedge shape, the connection strength between the resin body 20B and the metal plate 10A is increased, and the metal plate 10A is prevented from being lifted or rattled. Therefore, it is more preferable.

The embodiment shown in FIG. 9 corresponds to a modified example of the drainage lid X3 described above. As shown in FIG. 9, a protrusion 22c may be provided on each fitting portion 22B of the resin body 20B. Such a configuration is suitable for obtaining an anti-slip effect on the metal design surface of the drainage lid X3. The protrusion height of the protrusion 22c is preferably 0.3 mm or less. Projection 22c with a projection height of 0.3 mm or less
Then, even if the drainage palate X3 is stepped on the sole of the foot, it does not hurt without feeling excessive stimulation. Even if, for example, hair is mixed in the hot water flowing on the drain lid X3, the hair is not caught by the protrusion 22c.

In the drain cover X4 shown in FIG. 10, the plurality of fitting portions 22C provided on the resin body 20C are thickened from the lower surface 12 side to the upper surface 11 side corresponding to the shape of the opening 14A of the metal plate 10A. It has a second overlapping portion 22d that is wide and protrudes above the metal plate 10A and overlaps a part of the upper surface 11.
According to the present embodiment, the synergistic effect of the configuration in which the fitting portion 22C is locked to the opening portion 14A in a wedge shape and the configuration in which the second overlapping portion 22d presses the upper surface 11 of the metal plate 10A. Accordingly, the fixing of the metal plate 10A and the resin body 20C becomes more reliable and strong. Of course, the second overlapping portion 22d produces an anti-slip effect on the metal design surface of the drainage lid X4.

  In the drain cover X5 shown in FIG. 11, a plurality of downward annular convex portions 12 'are provided on the metal plate 10B. The downward annular convex portion 12 ′ is a portion where the lower opening peripheral edge portion of the opening portion 14 </ b> B of the metal plate 10 protrudes downward and is engaged with the resin body 20 </ b> C. It is formed by. As a result of the burring process, a rounded surface 14 'is formed in the opening 14B of the metal plate 10B, as shown well in FIG. The size of the rounded surface 14 'is approximately the same as the thickness of the metal plate 10B. Therefore, the opening portion 14B is spread upward. The fitting portion 22C of the resin body 20C has a form corresponding to the shape of the opening 14B, and has a larger diameter toward the upper side and is locked to the opening 14B in a wedge shape. The fitting portion 22C has a second overlapping portion 22b that protrudes upward from the metal plate 10B and overlaps a part of the upper surface 11.

  Also in the present embodiment, the locked state between the resin body 20C and the metal plate 10B can be ensured and strong, and it is suitable for thoroughly preventing the metal plate 10B from being lifted or rattling. . The second overlapping portion 22b also exhibits an anti-slip effect.

In the drain outlet lid X6 shown in FIGS. 12 to 14, a wide area opening 21 d that communicates with the plurality of openings 15 of the metal plate 10 is provided in the main body 21 </ b> A of the resin body 20 </ b> D. In the present embodiment, the plurality of openings 15 and the openings 21d communicating with the openings 15d are openings (drainage holes) through which the liquid can flow through the metal plate 10 and the resin body 20D of the drainage lid X6. There is no.
Even with such a configuration, the hot water flowing on the metal plate 10 can be appropriately drained below the drain cap X6 through the openings 15 and 21d.

  In the drain outlet lid X7 shown in FIG. 15, an additional metal plate 4 is laminated on the lower surface side of the resin body 20E. The additional metal plate 4 is, for example, stainless steel or copper made of the same material as the metal plate 10C, and the shape and size thereof are the same as those of the metal plate 10C. However, the material is not limited to this, and the material may be different. The additional metal plate 4 can be joined to the resin body 20E by placing the additional metal plate 4 together with the metal plate 10C in the molding die during molding of the resin body 20E. It is. The metal plate 10 </ b> C is provided with a plurality of fitting portions 22 </ b> D that are fitted into the openings 14 so as to exhibit the anti-slip function and partially protrude from the upper portion of the metal plate 10 </ b> C. There is no portion corresponding to such a fitting portion 22D. The additional metal plate 4 does not need an anti-slip function, and the additional metal plate 4 exhibits the effect of preventing dirt on the lower surface side of the drain port lid X7, so that the lower surface is as smooth as possible. This is because it is desired. However, instead of this, the additional metal plate 4 may be provided with a plurality of openings, and a part of the resin body 20E may be fitted into the openings.

  The additional metal plate 4 is provided with an opening portion 15 that communicates with the opening portion 15 of the metal plate 10C and the opening portion 21c of the resin body 20E. The series of the opening portions 15, 21c, and 40 is formed of the metal plate. An opening (drainage hole) that allows the liquid on 10C to flow downward of the drainage lid X7 is formed. A pair of upper and lower auxiliary members 5A and 5B are vertically provided through the four corners of the drainage lid X7 or in the vicinity thereof. The lower auxiliary member 5B has a protruding portion that protrudes below the additional metal plate 4, and this protruding portion is a portion that functions as a support leg portion of the drain port lid X7. At least the lower surface portion of the projecting portion can be made of a slip-proof resin or rubber. The upper auxiliary member 5A is inserted into the opening provided in the metal plate 10C and the resin body 20E from the upper side, and is connected to the lower auxiliary member 5B, whereby the lower auxiliary member 5B. Is to prevent the metal from falling off below the additional metal plate 4. As a means for connecting the upper and lower auxiliary members 5A and 5B, for example, a means for providing a screw portion on both of them and screwing them together, or a convex portion on one side and a hole on the other side, Various means such as means for press-fitting the convex portion into the hole can be used.

  According to this embodiment, since the lower surface of the resin body 20E is covered with the additional metal plate 4, it can prevent that the lower surface of the resin body 20E becomes dirty. The additional metal plate 4 itself is less likely to be contaminated based on the material, and even if it is contaminated, the cleaning becomes easy. Therefore, it is more preferable to make the drainage lid X7 hygienic and easy to clean. In addition, since the additional metal plate 4 is laminated, an effect of increasing the overall strength can be obtained while reducing the thickness of the drainage lid X7.

In the drain cover X8 shown in FIG. 16, additional openings 41 are provided at the four corners of the additional metal plate 4 or in the vicinity thereof, and the resin body 20F is inserted into the additional opening 41 and added. A portion 29 projecting downward from the metal plate 4 is provided. This portion 29 is a leg portion 29 for supporting the drainage lid X8.
According to this embodiment, unlike the embodiment shown in FIG. 15, it is not necessary to use other members such as the auxiliary members 5A and 5B, and the supporting leg 29 can be provided. Therefore, it is preferable in reducing the total number of parts and reducing the manufacturing cost.

In the drain outlet lid X9 shown in FIG. 17, the resin body 20G includes a substantially flat plate-like main body portion 21B and an upright plate portion 28 that is integrally connected to the main body portion 21B and rises upward from one side edge thereof. It is set as the structure which has.
