Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to the improvement of bathtubs, particularly bathtubs molded from FRP or other molding materials.

(Prior art) In bathtubs with relatively shallow bottoms, such as Western-style bathtubs, grips such as handles and bars are attached to the inner wall of the bathtub body or attached to the upper edge of the bathtub body to prevent slipping during bathing. A recessed part is formed in the part, and this is used as a gripping part, and by gripping the recessed part, it is possible to enter and exit the bathtub in a stable state, and also to take a bath.

(Problems to be solved by the invention) In the conventional structure described above, especially in the structure in which a gripping body is attached, the gripping body is attached parallel to the inner wall of the bathtub body, so when entering and exiting the bathtub, This poses an ergonomic problem, as the user has to grasp the grip from the side, which can lead to failure in gripping or requiring more grip strength than expected to grip it securely. In this case, there is a problem in that the hand rests on the edge of the recess, making it slippery and dangerous.

(Specific means for solving the problem) This invention was devised in view of the above-mentioned problem, and the two opposing upper edges of the bathtub body are formed into wide surfaces, and the opposite upper edges of the bathtub body are formed into wide surfaces. a pair of recesses are formed at the positions where the handle is to be held, and a vertical side surface perpendicular to the upper edge is formed in the recess, the vertical side surface is used as a mounting surface of the hand grip body, and the hand grip side edge of the hand grip body is parallel to the vertical side surface. The specific means is that the handle body is attached to the vertical side surface of the recess, and the side edge of the handle body attached to the vertical side surface of the recess is positioned parallel to the vertical side surface, whereby the upper edge of the bathtub body If you extend your hand along the curve, you will be able to hang your hand on the handle body in a very natural way, and you can easily put your hand on it and take a stable posture without much grip strength.The structure is ergonomically optimal. At the same time, it does not cause dangerous situations such as slipping, and the above problems can be solved in all aspects.

(Example) Next, this invention will be explained in detail with reference to illustrated examples.

The embodiment shown in FIG. 1 is an example in which this invention is applied to a molded bathtub made of FRP, enamel, stainless steel, ceramic, etc., and the bathtub body 1 is molded from the above-mentioned molding material.
, two upper edges 2A and 2B parallel to the length direction are formed wider than the other upper edges 2C and 2D, and each of these upper edges 2A and 2B has a pair of recesses 3. is formed. These recesses 3 are provided at positions facing each other, and the positions are almost the same as the mounting position of the grip in the conventional structure, and in the example shown, the side wall 11 of the bathtub body 1 on the backrest side. Opposing foot side side wall 1
It is formed at a position closer to 2.

The recess 3 is formed at the same time as the bathtub body 1 is formed. As shown in the figure, its shape is such that the surface on the tank side is open, the two side surfaces 31 and 32 of the planar L-shape form vertical sides, and the bottom surface 33 has a slope surface. A handle body 4 made of plastic or metal is attached to a vertical side surface 31 in the longitudinal direction of the bathtub body 1, that is, perpendicular to the upper edges 2A, 2B.

In the illustrated example, the hand grip body 4 is shaped like a thick plate and has a flat upper surface, so that a comfortable posture can be maintained by resting the palm of the hand on the upper surface. As shown in the figure, the mounting position of the body is preferably at a height close to the upper surface of the upper edge, but the handle body in this invention is not limited to the above-mentioned shape, and the handle body 4 is mounted vertically. When attached to the side surface 31, the handle side edge 4
2 may face the slope surface of the bottom surface 33 and be located parallel to the vertical side surface. By extending your hand along the edges 2A and 2B, you can easily reach the handle side edge 42 (see FIG. 1). Handle body 4
The mounting structure of the handle body 4 is as shown in Fig. 3.
In addition to installing a bolt 41 in the side surface 31 and passing the bolt through the side surface 31 in a water-tight manner and securing it with a nut from the back side of the side surface 31, as shown in FIG. The handle body 4A may be attached to the seat plate 51 of the mounting bracket 5 by dovetail fitting means. Further, as shown in FIG. 5, a handle body 4B is integrally molded with a concave body 6 made of a molded body (a molded body such as plastics) formed similar to the shape of the concave part, and this is fitted into the concave part 3. In either case, the upper surface of the handle body is located flush with or below the upper edges 2A, 2B of the bathtub body 1, and the handle body is arranged such that the upper surface thereof is located flush with or below the upper edges 2A, 2B of the bathtub body 1, and It does not protrude upwards and is positioned so that it does not interfere with the bath lid. In addition, the side surface 32 of the recess so that the recess 3 in the upper edges 2A, 2B of the bathtub body 1 is completely covered by the bath lid.
The upper surface of the side has a width sufficient to support the bath lid.

(Effects of the invention) As described above, according to this invention, the two opposing upper edges of the bathtub body are formed into wide surfaces, and a pair of recesses are formed at opposing positions of the upper edges, respectively. A vertical side surface perpendicular to the upper edge is formed in the recess, the vertical side surface is used as a mounting surface for the hand grip body, and the hand grip body is mounted with the hand side edge of the hand grip body positioned parallel to the vertical side surface. In particular, since the handle side edge of the handle body attached to the vertical side surface of the recess is positioned parallel to the vertical side surface, this allows the user to extend his/her hand along the upper edge of the bathtub body. The hand can be placed on the hand grip in a very natural manner, and it is possible to easily hold the hand and take a stable posture without much grip strength, resulting in an ergonomically optimal structure and the prevention of dangerous slips and the like. It is possible to solve the above-mentioned problems in all aspects without causing any problems.
