Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub, and more particularly to a bathtub having steps.

[0002]

2. Description of the Related Art Conventionally, a bathtub made of a reinforced plastic in which a gel coat layer and a reinforcing layer are laminated in this order is known, and in particular, a step is provided on an inner peripheral wall thereof.

[0003] This type of bathtub has the drawback that the surface thereof is formed smoothly including the steps, so that it is slippery. Was. For this reason, it has been proposed to decorate a mold portion corresponding to a step of a bathtub with an embossment, a depression, a groove, or the like, and to form an embossment on the surface of the step to prevent slippage.

[0004]

[Problems to be Solved by the Invention] However, the emboss formed on the step of the bathtub by decorating such a mold with embossment is shallow, and
Since the entire bathtub is formed of the same material, there is a problem that the anti-slip effect cannot be sufficiently exhibited.

The present invention has been made in view of the above problems, and provides a bathtub having a step having a non-slip effect.

[0006]

According to the present invention, in a bathtub having a step formed on an inner peripheral wall, an uneven portion is formed on the step, while a convex and concave portion is formed on the back surface of the rubber plate corresponding to the step. The rubber plate is attached to the step by fitting the convex and concave portions of the rubber plate to the concave and convex portions of the step.

[0007]

The rubber plate is attached to the step provided in the bathtub, and the concave and convex portions formed on the back surface of the rubber plate are fitted into the concave and convex portions formed in each step.

[0008] As a result, the step is provided with a rubber plate having a different coefficient of friction from that of the bathtub, so that the foot can be reliably caught and exhibit a non-slip effect.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a plastic bathtub. The bathtub 1 is formed by laminating a reinforced plastic, that is, a gel coat layer, and a reinforcing layer in which unsaturated polyester resin and glass fiber are mixed in this order. It is formed by a hand lay-up method or a spray-up method. In the bathtub 1, a step 2 as a step is provided on the inner peripheral wall when taking a bath.

By the way, in this step 2, the uneven portion 2
a is formed. On the other hand, the uneven portion 2 of this step 2
rubber plate 3 having convex and concave portions 3a formed on its back surface corresponding to a
Is prepared. In step 2 described above, the rubber plate 3 is attached by fitting the convex and concave portions 3a to the concave and convex portions 2a. The rubber plate 3 preferably has a hardness of 40 or less so as to be elastically deformable, and has a specific gravity of 1.5 or more so as not to float. Further, when the rubber plate 3 attached to the step 2 is stepped on, the rubber plate 3 is elastically deformed to increase the degree of fitting of the step 2 to the uneven portion 2a,
In order to provide a sufficient resistance to the rubber plate 3 coming out,
The thickness is preferably 5 mm or more, and preferably 10 mm or more.

The frictional resistance of the rubber plate 3 can be increased by forming an uneven pattern on the surface of the rubber plate 3.

As described above, since the rubber plate 3 is attached to the step 2 of the bathtub 1, when a foot is put on the rubber plate 3 during bathing, the rubber plate 3 is elastically deformed while its convex and concave portions 3 a are formed in the step 2. At the same time, it is possible to prevent the rubber plate 3 from separating due to the frictional resistance of the rubber plate 3 itself.

[0014]

As described above, according to the present invention, a rubber plate is formed by forming an uneven portion on a step provided on the inner peripheral wall of a bathtub and forming a concave and convex portion corresponding to the uneven portion of the step on the back surface. By fitting the protrusions and recesses to the protrusions and recesses of the step and attaching the step to the step, the material of the step is different from that of the step, and the rubber plate having a large frictional resistance makes it easy to catch the foot. Is reliably prevented from slipping, and a bathtub having a safe step can be obtained.
