Description

[Detailed Description of the Invention] The present invention relates to a bathtub in which a predetermined color pattern is applied to the surface of a flange attached to the upper edge of the bathtub body.

BACKGROUND ART Conventionally, bathtubs have been used in which various colored patterns are applied to the surface of an apron installed on the outer surface of a bathtub body.

However, there are no colored or patterned flange parts on the upper edge of the bathtub body, and in the case of stainless steel bathtubs, the flange part is made of the same material as the bathtub body. It was inevitable that I would feel great.

By the way, in conventional bathtubs, as shown in Figure 1,
The upper edge of the bathtub body 1 is bent outward to provide a joining edge 2, and the upper surface 3B of the flange 3 having the outer surface 3A is superimposed on the joining edge 2, and the joint is joined by seam welding or the like. Since the edge of the part was polished to a smooth finish, when a layer of hollow or an oxide film 4 is to be formed on the surface of the flange 3, the irregular edge 4A of the layer 4 that forms the color pattern is This poses a problem in that it is exposed on the surface and looks unsightly, reducing the commercial value of the bathtub.

For this reason, it was not possible to immediately apply colored patterns to the surface with the conventional structure.

The present invention solves the above problems and provides a bathtub in which the irregular edges of the colored pattern layer attached to the surface of the flange are not exposed to the outside. It is constructed in the shape of a bottomless frame, and has folded parts bent inward at the lower edges of both the inner and outer side parts, and further has a joining edge extending downward from the inner end of the folded part of the inner side part. It is characterized in that a colored or patterned layer is applied to the entire outer surface of both side surfaces, the top surface, and both folded parts of the flange excluding the joint edge, and the joint part is joined to the bathtub body.

In FIG. 2, the bathtub of the present invention consists of a bathtub body 11 in the form of a bottomed case made of stainless steel plate, etc., and a flange 12 joined to the upper edge of the bathtub body 11, and a heat insulating material 13 is provided on at least the front side of the body 11. An apron 14 is provided therebetween.

In Figure 3, the flange 1 is made of stainless steel plate, etc.
2 to the upper surface portion 12A and the inner surface portion 12B1 connected thereto.
The outer surface portion 12C forms a bottomless frame shape, and the lower edges of both the inner and outer side surfaces 12B and 12C are provided with folded portions 12D and 12E that bend inward, respectively.
The joining edge 1 is directed downward from the inner edge of the folded edge 12D of 2B.
2F will be extended and integrally formed by press working.

Excluding the joint edge 12F portion of this flange 12, the entire range of both folded parts 12D, 12E, both side parts 12B, 12C, and upper surface part 12A is coated with a single layer of hollow or a colored layer of oxide film (chromic acid film) on the outer surface. A color and pattern layer 15 is formed.

When joining this flange 12 to the bathtub body 11,
The inner surface of the joint edge 12F is overlapped with the outer circumferential wall surface of the bathtub body 11 and joined together by seam welding, etc., and at least one surface of the outer wall surface of the bathtub body 11 is provided with a heat insulating material 13 and an appropriate color and pattern if necessary. Install the strained apron 14 to complete the bathtub.

Alternatively, as shown in FIG. 4, the lower end surface of the joint edge 12F of the flange 12 may be brought into contact with the upper end surface of the bathtub body 11, and the joint portion may be joined together by MIG welding or the like. As shown in FIG. 2, a step 16 is formed at a certain height on the upper end of the bathtub body 11, the joint edge 12F of the flange 12 is placed along the inner surface of the upper edge, and seam welding is performed at the joint. They may be joined together.

In any of the cases described above, the color applied to the flange 12 and the irregularly shaped edge portions 15A of the pattern layer 15 are hidden on the lower surfaces of the folded parts 12D and 12E. The edge portion 15A does not appear outside.

Therefore, by forming the desired color and pattern layer 15 on the flange 12, the product value does not decrease as in the conventional case, and the inner and outer side surfaces 12B and 12G and the folded portions provided in series with each other can be used. The irregularly shaped edge portion 15A of the colored pattern layer 15 can be accommodated in the lower surface of the step formed between the layer 12D and the layer 12E, so that the so-called "partition" can be made beautiful.

Therefore, according to the present invention, the flange 12 provided at the top of the bathtub can be decorated with any color tone or pattern, and by applying a warm color tone to the flange, warmth is imparted to the stainless steel bathtub. It is possible to obtain a colorful bathtub that has not been seen before.

In addition, according to this proposal, by applying it to stainless steel bathtubs, the advantages of stainless steel, such as light weight, cleanliness, heat resistance, impact resistance, heat retention, workability, and durability, can be taken advantage of, while the disadvantages of stainless steel can be taken advantage of. It can improve the coldness caused by cold weather.

Further, by making the color pattern on the flange part and the color pattern on the apron the same or related, a very unique bathtub can be obtained.

In addition, a stepped portion is simply formed between the inner side surface portion 12B and the folded portion 12D as a shape for coloring applied to the flange 12 or for end treatment of the pattern layer 15, so that it is difficult to clean the flange 12. It will not cause any trouble.
