  In order to achieve the above object, a bathtub according to claim 1 of the present invention (hereinafter referred to as “tub of claim 1”) has a waist receiving portion that is raised stepwise from the bottom surface of the bathtub. In the bathtub formed along at least one portion of the waist receiving portion, the waist receiving portion is formed such that the center portion in the width direction of the waist receiving surface is formed in an upward slope toward the center of the bathtub, and the width of the waist receiving surface. Both directions are formed in a downward slope toward the center of the bathtub.

  The bathtub according to claim 2 of the present invention (hereinafter referred to as "tub of claim 2") is the bathtub according to claim 1, wherein one waist support portion is formed on one side in the longitudinal direction of the bathtub, The other bathtub inner wall surface in the longitudinal direction of the bathtub is characterized in that the lower end portion rises from the bathtub bottom surface with a steep slope and the upper end portion has a gentle slope.

  The bathtub according to claim 3 of the present invention (hereinafter referred to as "tub of claim 3") is a substantially flat surface having a stepped height from one side in the longitudinal direction of the bathtub in the longitudinal direction of the bathtub. A second waist support portion provided at a position higher than the first bottom support portion and having a stepped height from the center bottom surface on the other side in the longitudinal direction of the bathtub. And the inner wall surface of the bathtub on the side where the second waist support portion is provided has a lower end that rises steeply from the edge of the second waist support portion, and an upper end that is a gentle slope. It is characterized by that.

  The bathtub according to claim 4 of the present invention (hereinafter referred to as "tub of claim 4") is the long side of the bathtub arranged on the bathroom washing area side in any of the bathtubs of claims 1 to 3. The upper end edge of the bathtub is characterized in that the portion facing the bottom surface of the bathtub where the waist receiving portion is not formed is lower than the other portions.

In the present invention, the height of the waist receiving portion is appropriately determined depending on the depth of the bathtub, but it is preferable to set the height so that a standard adult can take a whole body bathing in a posture of sitting down.
Moreover, in the bathtub of Claim 3, although the height of a 2nd waist receiving part is suitably determined by the depth of a bathtub, it is set as the height which a standard adult can take a half body bath in the posture which sat down. preferable. Specifically, the distance from the upper edge of the bathtub to the waist receiving portion is preferably about 30 to 40 cm.

  The distance between the first waist support portion and the second waist support portion, that is, the length of the central bottom surface in the bathtub longitudinal direction is not particularly limited, but is preferably about 40 cm.

  The bathtub of the present invention is not particularly limited, and examples thereof include fiber reinforced plastic products, stainless steel products, and enamel products.

  In the bathtub according to the present invention, the central portion in the width direction of the waist receiving surface of the waist receiving portion is formed in an upward gradient toward the central portion of the bathtub, and both sides in the width direction of the waist receiving surface are inclined downward in the central direction of the bathtub. Therefore, even when sitting on the waist receiving surface shallowly, the buttocks are difficult to slip, and a stable sleeping state can be maintained. And since the both sides of the width direction are formed in the downward slope toward the said center bottom face side, when draining the hot water and water in a bathtub, or washing water does not accumulate on the waist receiving surface of a waist receiving part.

  In the bathtub according to claim 2, one waist receiving portion is formed on one side in the longitudinal direction of the bathtub, and the other inner wall surface of the bathtub in the longitudinal direction has a lower end rising steeply from the bottom of the bathtub, and an upper end portion. According to the above invention, half-bath bathing is possible when sitting on a stepped portion, and bathing with a height is carried out in a posture where the back is placed on an upper gentle-gradient backrest relative to the stepped portion. Even a person can use a sleeping bath that can be used to the shoulder. Also, by sitting deeply on the steep backrest at the lower part, a bather of normal height can make a deep conventional bath with a standing posture. Further, in the case of a bather who is short in height, the posture can be maintained by the waist receiving portion functioning as a leg rest for preventing slipping of the body.

The bathtub of claim 3 is provided with a first waist receiving portion having a substantially planar shape that is stepped higher than the central bottom surface on one side in the longitudinal direction of the bathtub, and is stepped from the central bottom surface on the other side in the longitudinal direction of the bathtub. The inner wall surface of the bathtub on the side on which the second waist support portion is provided has a lower end thereof, and a second waist support portion provided at a position higher than the first waist support portion. Since the upper part rises steeply from the edge of the second waist receiving part and the upper end part has a gentle slope, if you take a bath with the waist on the first waist receiving part, you can take a whole body bath In addition, if you sit deeply in the second waist-receiving part, you can take a half-body bath, sit down shallowly from the center of the second waist-receiving part to the bottom of the center, and the gentle slope part of the inner wall of the bathtub If you put your back on the back, you can enjoy sleeping in a stable posture.
In addition, the first waist receiving portion and the second waist receiving portion, which are stepped higher than the center bottom surface, are used when the bather has taken a full body bathing or half body bathing posture. The posture can be maintained by placing the sole on the rising surface or the edge of the waist support part 2, and even for a bather who is short in height, the body does not slip into the center bottom side and is safe.

  In the bathtub of claim 4, the bathtub upper end edge on the long side of the bathtub arranged on the bathroom washing area side is lower because the portion facing the bottom surface of the bathtub where the waist receiving portion is not formed is lower than the other portions. By setting the part to be in a straddling position, it is easy to straddle the edge of the bathtub, and it is possible to prevent an accident that the leg rests on the waist receiving part or the posture is lost.

Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.
