Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for manufacturing a top plate with an aquarium. The present invention provides a new manufacturing method for attaching to a top plate that has been affixed. The main effects of the present invention are that it is possible to obtain a top plate with a water tank that is excellent in design, has good water drainage, is easy to manufacture, and is highly economical. FIG. 2 is a partially enlarged sectional view of a top plate with a water tank obtained by the manufacturing method.

[Conventional technology]

As a conventional technique for manufacturing 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 hole (A) for inserting a stick is formed, is adhered to a decorative board (C). Next, as shown in the partially enlarged 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 shaped into a sink shape. At the same time, cut to form the opening end face of the top plate.

Furthermore, after smoothing the back surface of the reinforcing resin layer, the aquarium is brought into contact with the aquarium, and the urethane resin layer for adhesion is filled into the recess on the back side of the aquarium flange by pressing with the mounting bracket. The aquarium was attached to the top plate by injection and hardening.

[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 finishing the cutting process, the reinforcing urethane resin layer (E) is attached from the back side by bringing the water tank into contact with it. Since it is crimped using metal fittings, it must have sufficient strength to withstand this crimping strength. Therefore, the reinforcing resin layer E needs to have a thickness of approximately 5 mm to 10 mm, which causes a significant deterioration in appearance. Moreover, since the opening end face of the top plate is formed in advance before installing the aquarium, it is virtually impossible to completely align the opening end face with the inner peripheral edge of the aquarium, so the aquarium protrudes. This also deteriorates the appearance and is a disadvantage since a portion is formed.

Furthermore, the corners formed by the protruding portion of the aquarium and the end face of the top opening tend to attract dirt, dust, etc., which poses a problem not only in terms of appearance but also in terms of hygiene. Further, in terms of manufacturing, it is necessary to cut and finish both the opening end face 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, a thermosetting resin decorative board is attached to a wood base material, and a part of the back surface of the decorative board is removed from the wood base material part of the top plate. Then, an annular recess is cut and formed which is larger than the width of the flange of the water tank and has approximately the same shape.
A top plate opening with a top plate flange is formed by cutting, leaving a part of the inside of this cut recess, and a thin waterproof synthetic resin layer is formed on the back side of the thermosetting resin decorative board in the recess before curing. crimping the flange of the aquarium, and injecting an adhesive thermosetting resin liquid into the recess surrounded by the back surface of the aquarium and the open end of the wood base material of the recess;
The present invention provides a novel method for manufacturing a top plate with a water tank, characterized in that the top plate flange portion is cut and removed along the inner circumferential edge of the flange portion of the water tank after hardening.

The top plate with water tank shown in FIG. 8b is manufactured by injecting the urethane resin 23 and cutting off the top plate flange 18 after hardening.

〔Effect of the invention〕

As described above, according to the method of manufacturing a top plate with an aquarium of the present invention, first, as for the mounting position of the aquarium, as in the conventional example, the plywood base plate 11 as a core material is
The current cutting recess 16 is formed at an arbitrary position on the top plate made by pasting the melamine resin decorative board 12 and the plywood base material 11, rather than forming an opening in the aquarium. It has the advantage that the mounting position can be set freely. Furthermore, when forming the recessed portion, a part of the back surface 13 of the melamine resin decorative board is also cut at the same time, so that the adhesive that adheres the melamine resin decorative board and the plywood base material is completely cut and removed. I can do it. Therefore, a thin layer of waterproof urethane resin 20 is formed in the recess.
This has the advantage of improving the adhesiveness between the decorative board and the back surface 13 of the decorative board, thereby increasing the waterproof effect. Next, a major feature of the manufacturing method according to the present invention is that the inner side 17 of the cutting recess 16
The purpose is to form an opening 19 of a top plate provided with a top plate flange 18 by leaving a part of the top plate. This top plate flange 18
This has the effect of forming a thin layer of waterproof urethane resin on the back side of the decorative board of the cutting recess 16 and further preventing the urethane resin from overflowing to the top plate opening 19 side when the flange 15 of the water tank 14 is crimped. . Further, urethane resin 23 for fixing the aquarium is injected into the recess 22 surrounded by the back surface of the aquarium and the open end surface 21 of the plywood base material, and after hardening, it is applied to the top plate flange 18 along the inner peripheral edge 24 of the flange of the aquarium. Since the opening end 28 of the melamine resin decorative board, the opening end 29 of the waterproof urethane resin, and the inner peripheral end 10 of the flange part of the aquarium are of the same size, the appearance is extremely excellent. It has the advantage of being Furthermore, since the flange portion 15 of the water tank is crimped onto the waterproof urethane resin layer formed thinly on the back side of the decorative board of the cutting recess 16 before it hardens, the thickness of the resin layer is 0.5.
It is characterized by being extremely thin, ranging from mm to 1 mm, and in addition, the flange portion 15 of the aquarium, the urethane resin 20, and the melamine resin decorative board 12 are completely integrated in close contact with each other. Therefore, the synthetic resin layer at the opening is not as thick as the conventional one, which is 5 mm to 10 mm, which has the advantage of a very beautiful appearance, and also has the advantage of being excellent in draining water and having good waterproof properties. Furthermore, since the opening end surface from the opening end of the decorative board to the water tank is flush with no steps, there is an advantage that dirt and dust do not adhere to the opening end, making it hygienic. Further, since there is no need to previously provide openings in the wood base material to which the thermosetting resin decorative board is attached, there is an effect that manufacturing is extremely easy.

In addition, the thermosetting resin decorative board referred to in the present invention includes melamine resin decorative board, dap resin decorative board, polyester resin decorative board, etc., as well as metal foil such as stainless steel foil and aluminum foil and thermosetting resin impregnated prepreg. Includes hot-press molded metal foil decorative board. Next, the wooden base material to which the decorative board is attached refers to plywood, particle board, fiber board, etc. Further, the shape and dimensions of the top plate flange provided at the top plate opening are not limited in any way, and may be of any type as long as it has the effect of preventing the waterproof synthetic resin from overflowing toward the top plate opening. Note that polyurethane resin, epoxy resin, silicone resin, etc. are optimal for this waterproof synthetic resin. Further, in order to form these synthetic resin layers thinly, a liquid synthetic resin is poured into the decorative board, or a semi-curved synthetic resin is applied to the back surface of the decorative board. Next, the adhesive thermosetting resin used for fixing the aquarium in the present invention refers to polyurethane resin, polyester resin, epoxy resin, etc. There is no particular limitation on the method of cutting and removing the top plate flange after the resin has hardened, but for example, as shown in the enlarged view of FIG. The guide roll 33 is cut along the decorative board 32 and further along the inner circumferential surface 34 of the aquarium using a knife 35. In addition, 36 shows the flange part of the water tank, 37 shows the inner peripheral end of the flange part of the water tank, and 3
8 is a waterproof synthetic resin. Next, the material, shape, and mounting manner of the aquarium installation aid referred to in the present invention are not limited to those shown in FIGS. 8 and 9. For example, as shown in the perspective view of FIG. You may also use

As explained above, according to the method of manufacturing a top plate with an aquarium of the present invention, the opening end of the top plate is aligned with the opening end of the aquarium, and the waterproof composition is only 0.5 mm to 1 mm away from the thermosetting resin decorative plate on the surface. Since the water tank is attached through the resin layer, it has the advantage of being excellent in water drainage, as well as having an extremely good appearance and excellent design. Further, since there is no step difference in the opening surface, there is an advantage that dirt and dust do not adhere to the opening surface, making it sanitary. Furthermore, instead of using a wood-based base material with openings provided in advance, annular cutting recesses are provided from the base material side at arbitrary positions on the top plate to which the base material and the thermosetting resin decorative board are attached. Since the water tank is installed at the water tank mounting position, the position of the water tank is highly arbitrary, and manufacturing is easy, making it extremely useful in practice.
