Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a top plate with a water tank used for sinks, washstands, etc.

Generally, this type of top plate with an aquarium is constructed by forming a window hole in the top plate and fixing the aquarium to this window hole.
The fixation is done by welding 20 as shown in FIG. 4A, and as shown in FIG.
22 and was trying to tighten the knot. However, all of these materials have poor workability, and when an aquarium treated with enamel is used, there are problems such as cracking of the enamel.

For this reason, the inventor poured a thermosetting resin between the window hole of the top plate and the aquarium and cured it, thereby combining the top plate and the aquarium into one body and forming the edge of the window hole of the top plate. I thought about something that would be waterproof. However, in this case, the thermosetting resin is only bonded to the top plate and the flat surface of the aquarium.
When a large external force is applied, there is a risk that the top plate and the water tank may separate, resulting in a lack of reliability.

The present invention was made in view of these points.
The aim was to make it possible to connect the top plate and the water tank easily and reliably, and to greatly improve reliability.

An example of this will be explained below with reference to the drawings.
Reference numeral 1 denotes a top plate, which is made of a metal material such as stainless steel, and has window holes 2 formed at appropriate locations. Then, the edge of this window hole 2 is bent and a top plate 1 is placed.
A bent piece 3 is provided facing the surface and forming a gap with the top plate 1. 4 is a water tank in which an opening edge flange 5 is superimposed on the bent piece 3 of the top plate window hole 2, and like the top plate 1, this is also made of a metal material such as stainless steel. The water tank 4 is made by polymerizing the entire circumference between the bent piece 3 of the top plate window hole 2 through a soft material 6 having air permeability such as foamed urethane, and epoxy and urethane are applied to the outer peripheral part of the polymerized part. A casting resin 7 such as the above is poured, and the casting resin 7 is hardened and fixed to the window hole 2 of the top plate 1.

FIG. 3 shows the state in which the casting resin 7 is poured, and 8 is a base on which the top plate 1 is placed, and has a soft mat 9 for positioning the top plate 1 and the water tank 4. 10 is a top plate window hole 2 from above the water tank 4.
A soft packing 11 is interposed between the top plate 1 and the water tank 4, and is a mold that is covered so as to cover the overlapping portion between the top plate 1 and the water tank flange 5. Reference numeral 12 denotes an injection hole provided in a part of the molding die 10, through which the casting resin 7 is poured, forming the top plate window hole 2 and the water tank flange 5.
Spread it around the outer periphery of the overlapped area and cure.

In the above configuration, the bent piece 3 of the top plate 1 and the water tank 4
The casting resin 7, which is injected into the outer periphery of the overlapping portion with the flange 5 and hardened, embraces this and integrates them. This casting resin 7 does not cause distortion to the top plate 1 and water tank 4 unlike welding, and even an enamel water tank can be integrated with the top plate 1 without the hassle of welding. You don't have to do a lot of work.

As described above, according to the top plate with a water tank of the present invention, the two can be integrated by simply injecting a casting resin into the outer periphery of the overlapping portion of the bent piece of the top plate and the flange of the water tank and curing it. It can be easily done even by an amateur, and since the casting resin is hardened while holding the bent piece of the top plate and the flange of the aquarium, the bonding strength is stronger than that of simple adhesive bonding. Reliability is also significantly improved, as the top plate and the water tank will no longer separate from each other even when a large external force is applied.
