しかし、このような浴槽では、入浴者が仰向けで寝るような体勢で入浴（寝浴）できるようになる一方、通常の浴槽と比べ上体が倒れているため、起き上がることに非常に苦労を要する。即ち、寝浴状態から出浴するためには浴槽内で立ち上がって出浴する前にまず寝浴状態から上体を起こす必要があるが、寝浴状態では肩を含む上体が浴槽内に位置するため、浴槽のリムを把持して上体を起こすためには、大きな力を腕に加えて上体を引き寄せる必要があり、非常に起き上がりにくい。また、寝浴状態では入浴者の臀部が背当て部より離れた位置にあるため、上体を起こした後、足を上体側へ引き寄せて立ち上がる必要がある。足を上体側へ引き寄せると、上体自体に後方へ向かう力が付与されてしまうが、寝浴ができる浴槽であると背当て部が後方へ傾斜しているため、また上体が倒れてしまうといった問題もある。 However, in such a bathtub, the bather can take a bath (sleeping) in such a posture as to sleep on his back, but the upper body is tilted compared to a normal bathtub, so it takes a lot of trouble to get up . In other words, in order to take a bath from the sleeping state, it is necessary to wake up from the sleeping state before standing up in the bathtub and taking a bath, but in the sleeping state, the upper body including the shoulders is located in the bathtub. Therefore, in order to raise the upper body by grasping the rim of the bathtub, it is necessary to apply a large force to the arm to draw the upper body, and it is very difficult to get up. Further, since the bather's buttocks are in a position away from the back pad in the sleeping state, it is necessary to stand up by raising the upper body and then pulling the foot toward the upper body. If you pull your foot toward the upper body, force will be applied to the upper body itself, but if it is a bathtub where you can sleep, the backrest will tilt backwards, and the upper body will fall over again. There is also a problem.

そこで、本発明は、寝浴浴槽における起き上がりと立ち上がりをサポート可能な手摺を備えた浴槽を提供する。 Then, this invention provides the bathtub provided with the handrail which can support the rising and rising in a sleeping bath.
