Abstract

PURPOSE: To provide a water drain port lid used for a water drain port of a synthetic resin water-proof pan whereby hands and feet are not injured even if they are held by hands or depressed by feet by covering the entire surface of a water drain port cover base material with synthetic resin coat of a specified thickness. CONSTITUTION: Synthetic resin coat 2 of 50 to 500μm in thickness is applied to the entire surface of a metallic water drain port cover base material 2. When the thickness is below 50μm, there are cases that the top end of burrs at the edge part is not covered with the synthetic resin, and the top end of burrs may be peeled off by shock, etc. On the other hand, use of coating material of 500μm or more becomes useless. Also, even if burrs produced in cutting are present at the edge part of the base material of the water drain port cover, it is covered with the synthetic resin with a thickness capable of filling them. Therefore, even if hands and feet touch the burrs, they are not injured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain pan cover for a waterproof pan, and more particularly to a drain cover for a bathroom in which the entire surface of the drain cover base material is coated with a synthetic resin.

[0002]

2. Description of the Related Art In recent years, it has been called a unit bath and the main body is FR
Bathrooms made of P are widely used not only in hotels but also in general households. This unit bath usually comprises a waterproof pan, a bathtub, and a side wall panel provided upright on a flange formed around the waterproof pan and the bathtub, and water is drained from a drain port provided in the waterproof pan. And a normal unit bus is SM
It can be produced by a known method such as C method, hand layup method, spray up method. For example, as SMC method, a glass fiber nonwoven fabric and an unsaturated polyester resin are alternately laminated in a mold, and this is laminated. Product is obtained by heating under pressure,
On the other hand, as a spray-up method, it is obtained by spraying an unsaturated polyester resin prepared by blending short glass fibers on the surface of a mold, and coloring this synthetic resin by blending an appropriate pigment. Is. Then, the coloring of the product surface is coated with a polyester resin called gel coat.

Now, a drain port lid made of synthetic resin or metal is usually fitted into a drain port provided in a waterproof pan provided for a washing place in this unit bath. However, since the synthetic resin drain port lid obtained by the hydration method or spray-up method has the glass fiber exposed on the back surface, there is a risk of injury when the lid is removed. Also, in the case of a metal drainage port lid, burrs left at the edge part when cutting from steel material may occur, which may cause injury.
Since it is made of metal, rust may occur. Further, the color difference is particularly remarkable with respect to the waterproof pan, the bathtub, the side wall panel, etc., and there is a drawback that a feeling of strangeness occurs.

[0004]

DISCLOSURE OF THE INVENTION The drainage port lid obtained by the present invention solves these drawbacks and does not cause injury even if it is held by a hand or stepped on with a foot, and does not cause rust. Also, the present invention provides a drain port lid whose color tone can be freely changed.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and its gist is a drain cover provided to a drain of a synthetic resin waterproof pan,
A film thickness of 50-500μ on the entire surface of the metal drain outlet lid base material
Of the synthetic resin film of the present invention. And, preferably, the synthetic resin as the coating material is a nylon resin, a fluorine resin, an epoxy resin,
The present invention relates to a drain port lid which is selected from vinyl chloride resin and the like, and which further contains a pigment for adjusting the color tone around the drain port lid in such a synthetic resin.

[0006]

In the drainage port lid of the present invention, the entire surface of the metal drainage port lid base material is coated with synthetic resin,
Even if there are burrs or the like at the time of cutting at the edge of the base material of the drainage port lid, it is covered with a synthetic resin with a thickness sufficient to fill it, so even if it comes in contact with it I have no more injuries to my legs. By mixing a pigment in the covering material, it is possible to match the color tone with the surrounding members used.

As the synthetic resin used as the covering material, the synthetic resin as described above is used, which has heat resistance enough to withstand use as a discharge port lid and is less likely to cause chipping or cracking of the coating due to drop or impact. To be selected. The thickness of this film is usually 50 to 500 μ, preferably 200 to 5 μm.
It is preferable to set it to 00 μ, and if it is 50 μ or less, there is a case where the tip of the burr at the edge portion is not covered with the synthetic resin, and there is a possibility of peeling due to impact or the like. Meanwhile, 5
This is because the use of the covering material of 00 μ or more is wasteful.

In the manufacture of the discharge port lid of the present invention, first, a drain port cover base material made of a steel plate or stainless steel processed into the shape of the drain port cover is obtained. Then, a primer treatment for degreasing the surface of the base material is performed. Then, the base material subjected to the primer treatment is immersed in the dissolved synthetic resin solution,
A synthetic resin is attached to the surface of this base material. Then, this is baked and dried to form a synthetic resin film having a thickness of 50 to 500 .mu. For the primer treatment, soapy water, a neutral detergent, etc. are used, and trichlene, carbon tetrachloride, benzine, etc. are appropriately selected.

[0009]

EXAMPLES The discharge port lid of the present invention will be described in more detail below. FIG. 1 is a perspective view of a discharge port lid base material 1 used in the present invention. In the figure, 1 ₁ is a horizontal portion that matches the surface of the waterproof pan, and 1 ₂ is a vertical portion that rises at 90 degrees. 1
₃ is a hole for water to pass through. This is obtained by punching and pressing a flat steel material. Now, in order to degrease the surface of the discharge port base material 1,
Primer treatment with trichlene, discharge outlet lid base 1
Wash the surface. On the other hand, a 6-nylon melt that serves as a coating material was prepared, the substrate 1 was dipped in this melt to form a coating film, and this was dried and baked.

FIG. 2 is a cross-sectional view of the drain port lid obtained here, and in the figure, 2 is a nylon resin film coated on the surface of the drain port lid base material 1. As shown here, exhaust palate obtained are almost uniformly nylon coating applied to the entire surface of the front and back and the hole 1 ₃ discharge palate substrate 1, protrusions such as burrs did not exist.

FIG. 3 shows an example of use of the drain port lid of the present invention, in which a drain groove 11 is formed in a waterproof pan 10 and the drain groove 1 is formed.
1 and concave portions 11 ₁ and 12 of the apron 12 provided upright here
FIG. 3 is a perspective view of the drainage cover fitted into ₁ . Of course, although not shown, the drainage groove 11 is provided corresponding to the flat portion of the drainage port lid.
It has a drainage port.

In the drainage port lid of the present invention, since the drainage port lid base material is completely covered with the synthetic resin film,
Burrs and the like existing on the edge portion of the drain cover material did not project to the outer surface, and the limbs were not injured even when the drain cover was touched. Further, since the metal drainage port base material is not exposed, there is an advantage that rust is not generated. Furthermore, it also has a feature that it can be co-ed with surrounding waterproof pans and aprons by giving a color tone to the synthetic resin that coats the base material.

[0013]

EFFECTS OF THE INVENTION The drain cover of the present invention has the above-mentioned structure, and is characterized by the safety of the human body and the feature of the drain cover itself that it can be matched in color with surrounding members used. Not only the waterproof pan of the bus,
It can be used as a drain lid in other waterproof pans.
