[Conventional technology]

As a prior art related to a top plate with a water tank, there is, for example, Japanese Patent Publication No. 57-34413. In this application, first, as shown in the perspective view of FIG. 2, a core material (R) in which a sink fitting hole (A) is formed is attached to C. Next, as shown in the partially enlarged cross-sectional view of Fig. 3, a reinforcing urethane resin layer (E) is injected onto the back side of the decorative board in the fitting hole (A), and after curing, the resin layer (E) and the decorative board (C) are aligned to the shape of the sink. Cut at the same time to form the opening end face of the top plate. Furthermore, after smoothing the back surface of the urethane resin layer, the water tank is brought into contact with it, and the urethane resin layer for adhesion is filled into the recess on the back side of the water tank flange by pressing it with the mounting bracket. The aquarium was attached to the top plate by injecting and curing the water.

[Problem that the invention seeks to solve]

According to the manufacturing method using the conventional technology, the reinforcing urethane resin layer (E) formed on the back side of the decorative board requires a cutting process with a knife after it hardens, and after cutting, it is removed from the back side by abutting a water tank. It is crimped using a mounting bracket, and requires sufficient strength to withstand this crimping strength. Therefore, the reinforcing resin layer has a thickness of approximately 5 mm to 10 mm.
It is necessary to have a thickness of mm, which causes a significant deterioration in appearance. Moreover, since the method involves forming the opening end face of the top plate in advance before installing the water tank, it is virtually impossible to completely match the opening end face with the inner circumferential edge of the water tank flange. Since a protruding part of the water tank is formed, this also deteriorates the appearance and becomes a drawback. Furthermore, dirt and dust tend to adhere to the corner formed by the water tank protrusion and the opening end of the top plate, which not only spoils the appearance but also poses a sanitary problem. Further, in terms of manufacturing, it is necessary to cut and finish both the opening end face of the top plate and the back side of the reinforcing urethane resin layer, which makes the process complicated.

The present invention solves the above-mentioned conventional drawbacks, and in summary, in a top plate member made by pasting a thermosetting resin decorative board on a wood base material, the open end of the thermosetting resin decorative board is attached to a water tank. A first open end that has approximately the same dimensions as the inner peripheral end of the flange portion, the open end of the wood base material is larger than the inner peripheral end of the aquarium flange portion, and smaller than the outer peripheral end of the aquarium flange portion, and has a thickness of approximately 1 mm. and a second open end larger than the outer peripheral end of the aquarium flange, and the aquarium flange comes into contact with the open end step of the wood base material formed by the aquarium flange, and the thermosetting resin decorative board To provide a top plate with an aquarium in which a gap between a protrusion and an aquarium flange and a recess on the back surface of the aquarium flange are filled with a thermosetting resin.

[Means for solving problems, their effects and examples]

Embodiments of the present invention will be specifically described below based on the drawings. First, FIG. 1 shows a partially enlarged sectional view of a top plate with a water tank having a novel structure according to the present invention. The top plate with a water tank in this figure is made of plywood base material 1.
In the top plate member formed by pasting the melamine resin decorative board 2 on the melamine resin decorative board 2, the open end 3 of the melamine resin decorative board 2 has approximately the same dimensions as the inner peripheral end 5 of the aquarium flange portion 4, and the open end of the plywood board base material 1. is larger than the inner peripheral end 5 of the aquarium flange portion, smaller than the outer peripheral end 6 of the aquarium flange portion, and has a thickness d of 1 mm, and a second opening end 8 larger than the outer peripheral end 6 of the aquarium flange portion.

This is a top plate with a water tank in which urethane resin layers 11 and 12 are filled and formed in a recessed part on the back side of part 4. Next, FIG. 4 is a perspective view showing an embodiment of the top plate with a water tank according to the present invention, and in terms of appearance, the open end 3 of the melamine resin decorative board 2 stuck to the plywood base material 1, the urethane resin open end 13, and The inner peripheral end 5 of the water tank flange portion has approximately the same dimensions. Next, FIGS. 5A to 5G are partially enlarged cross-sectional views of process drawings showing an embodiment of the method for manufacturing a top plate with a water tank according to the present invention. In the manufacturing method of the present invention, first, a plywood base material 1
and the melamine resin decorative board 2 are attached using a rubber adhesive or the like. Next, the melamine resin decorative board 2 of the plywood base material 1
An annular recess 15 having a width larger than the flange portion of the water tank and having substantially the same shape is cut from the back side 14 of the plywood base material, leaving a thickness of 1 mm on the side. Next, a melamine resin decorative board is formed in a portion 16 near the inner circumferential end of the annular recess 15 so that a first opening end 7 that is larger than the inner circumferential end 5 of the aquarium flange portion and smaller than the outer circumferential end 6 of the aquarium flange portion is formed. After cutting and forming the annular exposed portion 17 of No. 2 and partially cutting and removing the open end stepped portion 9 of the plywood base material, a part of the plywood base material 18 inside the annular exposed portion 17 is left and the ceiling is cut. The top plate opening end 20 provided with the plate flange portion 19 is formed by cutting. FIG. 6 shows a perspective view of the back side of the top plate member in which the annular recess 15 and the top plate opening end 20 are formed, and FIG. It is a partial enlarged view of the back side showing the defective part 21 of the open end step part 9 of the wood-based base material which is formed by removing it. Next, when attaching the water tank 22 to the annular recess 15 of this top plate, as shown in FIG. The resin layer 12 is injected and hardened. The injected urethane resin reaches the gap 24 between the water tank flange portion 4 and the annular exposed portion 17 of the melamine resin decorative board through the defective portion 21 of the opening end step of the plywood base material, thereby forming the urethane resin layers 11 and 25. do. After the urethane resin layers 11, 12, and 25 have hardened, the top plate flange 19 and the urethane resin layer 25 are removed by cutting along the inner peripheral edge 5 of the water tank flange using a cutting tool with a rotating blade such as a hand trimmer. Thus, the top plate with water tank of the present invention shown in FIGS. 1 and 4 is obtained. In the present invention, as shown in the partially enlarged sectional view of FIG. 8, before the urethane resin layer 12 is injected and formed, an L-shaped layer is formed from the back surface 26 of the open end of the wood base material 1 to the back surface of the aquarium flange portion 4. The aquarium mounting bracket 27 may also be screwed on. Further, FIG. 9 shows a partially enlarged perspective view of a water tank 28 with through holes used in another embodiment of the present invention, in which a plurality of through holes 29 are provided in a portion of the water tank flange portion 4 near the inner circumferential end 5. It is characterized by the fact that it is provided. FIG. 10 is a partially enlarged sectional view showing an embodiment of a top plate with a water tank using the water tank 28 with a through hole. This top plate with a water tank is characterized in that the urethane resin layers 11 and 12 are integrated through the through hole 29.

〔Effect of the invention〕

As shown above, the water tank top plate of the present invention is characterized in that the opening end 3 of the melamine resin decorative board, the urethane resin opening end 13, and the inner circumferential end 5 of the water tank flange portion have approximately the same dimensions. The appearance of the aquarium attachment part of the top plate is very clean and beautiful, and there is no corner curvature between the opening end of the top plate and the aquarium flange 4, which is the case with conventional products, so there is less dirt and dirt. It has the great advantage of not being contaminated with dirt and being hygienic. Also, the urethane resin opening end 13 exposed at the opening end of the top plate
The thickness is almost the same as the thickness of the first opening end 7 of the plywood base material, and compared to the conventional reinforcing urethane resin layer E, which had a thickness of 5 mm to 10 mm, it is extremely thin and has a smooth appearance. , it has the advantage of being beautiful. In addition, since the water tank is attached to the lower part of the open end of the top plate through a thin layer of urethane resin, it is easy to wipe off dirt and water droplets that have adhered to the top plate, and water is cleaned up easily. There are advantages. Furthermore, the most important feature of the structure of the top plate with a water tank of the present invention is that the first open end 7 and the second open end 8 are formed on the plywood base material 1, and the water tank flange portion is formed at the open end stepped portion 9 of the plywood base material. 4 are in contact with each other and are bonded by the urethane resin layers 11 and 12, which has the advantage that the thickness of the urethane resin layer 11 is uniform over the entire circumference of the tank flange, resulting in an excellent appearance. Further, in the present invention, the opening end step 9 is partially cut and removed to form a defective part 21 in the opening end step, and a through hole 29 is formed in a portion near the inner peripheral end of the water tank flange. It is also a feature that the urethane resin layers 11, 1 are provided.
2 has the advantage that the aquarium can be more firmly attached. Furthermore, according to the manufacturing method of the present invention, regarding the mounting position of the aquarium, instead of forming an opening in the plywood base material 1 in advance as in the conventional example, the plywood base material 1 and the melamine resin decorative board 2 are Since the annular recess 15 is cut and formed at an arbitrary position on the attached top plate member, it has the advantage that the mounting position can be freely set just before installing the water tank. Furthermore, the top plate flange 19 provided when cutting and forming the top plate opening 20 has the effect of preventing the resin from flowing out to the top plate opening 20 side when urethane resin is injected. .

Note that the wood-based base material referred to in the present invention refers to plywood, particle board, fiber board, etc., and the thermosetting resin decorative board includes melamine resin decorative board, dap resin decorative board, polyester resin decorative board, etc.
It includes a metal foil decorative board formed by hot-pressing molding of metal foil such as stainless steel foil or aluminum foil and prepreg impregnated with thermosetting resin such as phenolic resin. Next, the thermosetting resin used for filling the aquarium in the present invention includes urethane resin, polyester resin,
Refers to epoxy resin, silicone resin, etc. In addition, the missing part of the opening end step of the wood-based base material formed by cutting in the present invention is, in short, the one that is formed even if the opening end step, which is continuously formed in an annular shape, is partially cut away. The reason why a plurality of these are provided is to allow the thermosetting resin liquid to flow in and to defoam the air accumulated in the gap between the water tank flange and the annular exposed portion of the decorative board.

Next, the location of the through hole provided in the aquarium flange is limited to a portion near the inner peripheral end of the flange, in short, when the aquarium is attached to this top plate member, the through hole is located at the opening in the base material. This is to prevent it from overlapping the end step portion. The material and shape of the aquarium mount used in the present invention are shown in Figure 8.
The mounting bracket is not limited to the shape of the aquarium, and any type of fitting may be used. Next, the size and shape of the top plate flange that is cut and formed by the cutting method of the present invention are not limited, and in short, the size and shape of the top plate flange part that is cut and formed by the cutting method of the present invention are not limited. All you have to do is accomplish it. The method of cutting and removing the top plate flange is not particularly limited, but it may be cut along the inner peripheral surface of the aquarium using a device having a rotating blade such as a trimmer or router.

As explained above, according to the top plate with an aquarium and the manufacturing method thereof of the present invention, the opening end of the top plate is aligned with the opening end of the aquarium, and the thermosetting resin is only about 1 mm away from the thermosetting resin decorative plate on the surface. The water tank is attached through a layer, and the back side of the water tank flange is also filled with a thermosetting resin layer, so it has the advantage of excellent water drainage and an extremely good appearance and excellent design. has. Further, since there is no step in the opening, there is an advantage that dirt and dust do not adhere to the opening, making it sanitary. Furthermore, instead of using a wood-based base material with openings provided in advance, annular cutting recesses are cut from the base material side at arbitrary positions on the top plate member to which the base material and the thermosetting resin decorative board are attached. Since the aquarium is provided at the aquarium mounting position, the aquarium position is highly arbitrary, and manufacturing is easy, making it extremely useful in practice.
