Abstract

PROBLEM TO BE SOLVED: To enhance a reinforcing increase effect by externally fitting metallic groove shape fixtures or metallic fixtures with an H shape cross section to a rib. SOLUTION: The rib 11 is projectingly arranged on the rear side surface of the bottom board 1 of an FRP bathtub. A slope 21 and a pulling-out preventing projection 22 are disposed in opening part of the metallic groove shape fixtures 2. The fixtures 2 are externally fitted to the rib 11, the projection 22 is engaged with the side surface of the rib 11 and the fixtures 2 are prevented from easily coming off the rib 11. Thus, the fixtures 2 are externally fitted to the rib 11 so that the bottom board 11 of the bathtub is sufficiently reinforced. Besides, the slope 21 is arranged in opening part of the fixtures 2 so that the fixtures 2 are easily externally fitted to the rib 11. Moreover, the pulling-out preventive projection 22 is arranged in the opening part of the fixtures 2 so that the projection 22 is engaged with the side surface of the rib 11 to prevent the fixtures 2 from easily coming off the rib 11.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing structure for a product having a rib in which a rib is projected from a plate-like portion such as a bathtub, a bathtub with a washing place, or a waterproof pan.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Publication No. 62-17739
As described in Japanese Patent Application Publication No. 0-203, etc., it is known to reinforce a bottom plate of a bathtub and a washing place by protruding ribs vertically and horizontally on a back surface of the bathtub and the washing place.

[0003]

However, in the case where the ribs are protrudingly provided on the back surface of the bathtub or the washing place as in the prior art to reinforce it, the reinforcing effect can be enhanced by the plate-like portion such as the bottom of the bathtub or the washing place. Therefore, it is necessary to increase the thickness of the ribs or the thickness of the ribs, and therefore, the total weight is increased, the material is additionally required, and the reinforcing effect cannot be expected much.

[0004] The present invention has been made in view of such problems in the above-described conventional structure for reinforcing a product with a rib such as a bath tub. An object of the present invention is to provide a reinforcing structure for a product with a rib having a large increasing effect.

[0005]

In order to achieve the above-mentioned object, a reinforcing structure for a product with ribs according to the present invention is a reinforcing structure for a product with ribs having ribs projecting from a plate-like portion.
A groove-shaped metal fitting or an H-shaped metal fitting is externally fitted to the rib.

[0006] In the present invention, as the product with ribs,
What is necessary is that the rib is protruded,
Although not particularly limited, for example, a bath tub having a rib protruding from the bottom, a washing place, and the like can be given.

[0007] The material of the product with ribs is not particularly limited. For example, FRP, hard vinyl chloride resin,
Examples thereof include synthetic resins such as polyethylene and polypropylene, and wood and concrete.

In the present invention, the material of the groove-shaped metal fitting and the H-shaped metal fitting is not particularly limited as long as it can reinforce the product with ribs. Metals such as steel, brass, and aluminum can be used.

[Operation] In the reinforcing structure for a product with ribs according to the present invention, the grooved metal fitting or the H-shaped cross-section metal fitting is externally fitted to the rib. Sufficiently reinforced, it is easy to attach the groove-shaped metal fitting or the H-shaped metal fitting to the rib.
