Abstract

PROBLEM TO BE SOLVED: To provide a bath tub easier to go in and out for aged and handicapped people by processing a hollow having specified angle of depression and length in its slanted faces on an upper face of the rim facing the people to get in and out. SOLUTION: On the rim 2 of a bath tub 1 is processed a hollow 3 composed of two slanted faces coming down from the upper face of the rim. The angle of depression 3 of one slanted face is specified as 15-30 degree to the upper face of the bath tub rim while the length of other slanted face is specified as 35-50cm and its angle of depression specified as 0-90 degree to the horizontal level of the rim. Otherwise, a hollow with the depth less than 1.5cm and the horizontal length 5.0-15cm is processed on the rim on the position to meet the heel of the people when he sat on the rim 2 of the bath tub 1 on stretching out his leg toward the upper face of the rim.

ではない。2. Description of the Related Art In a conventional bathtub, the height of the bathtub edge on the entrance side is usually constant, and the upper surface of the bathtub edge is also uniformly flat. Japanese Utility Model Laid-Open Publication No. 3-27788 discloses a method in which a stool is placed on the edge of a bath tub and the stool is entered into the bath tub. However, even if you sit on the edge of the bathtub, place your feet one foot at a time on the upper surface of the bathtub, and straddle the edge of the bathtub into the bathtub, the height of the bathtub edge is constant. I had to raise it and straddle it. Therefore, it is conceivable to provide a concave portion on the upper surface of the bathtub edge so that the foot does not need to be raised high. Japanese Unexamined Patent Publication No. 61-55368 discloses a bathtub having a concave portion on the upper surface of the bathtub edge. The bathtub is provided with a concave portion to limit the location of spilling water. However, the concave portion is not provided in consideration of ease of operation.

In FIG. 3, a recess corresponding to the shape and size of a heel of a human having a height of about 150 cm to 190 cm is provided where the heel contacts the upper surface of the bathtub edge. (FIG. 3 shows a case where the user sits on the right edge.) Here, the depth of the recess is limited to 1.5 cm or more as the depth to which the heel falls easily, and the length of the recess is The horizontal length is limited to 5.0 cm or more and 15 cm or less. Here, if it is less than 5.0 cm, the heel cannot easily enter. Since the depth of a general bathtub is around 60 cm, if the depth of the concave portion is too deep to be 8.0 cm or more, the hot water is easily spilled when hot water is immersed or soaked, and the condition is poor. Further, the depth of the concave portion is limited to 8.0 cm or less, since it is sufficient that the lifting operation of the thigh is easy and the depth is large enough to accommodate the heel. The depth of the recess is preferably as small as possible and the heel can be easily accommodated. Therefore, the depth of the recess is more preferably 1.5 cm or more and 6.0 cm or less.
