Embodiments of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is an explanatory perspective view for explaining a bathtub as an example of an embodiment of the present invention, and FIG.
FIG. 3 is a cross-sectional view taken along line I-II, and FIG. 3 is an explanatory cross-sectional view for explaining a state in which a notch is closed.

In FIG. 1, reference numeral 1 denotes a bathtub having a portion projecting upward from a floor surface 2, and an apron stage 3 is provided at one end of the bathtub 1 in the longitudinal direction. A substantially rectangular cutout 4 extending from the upper surface of the side wall toward the floor 2 is formed on the side wall of the entrance and exit of the bathtub 1, and the bottom of the cutout 4 is located above the floor 2. I have. The notch 4 is provided with a box-shaped gate 5 that opens and closes the notch 4 so as to be slidable in a liquid-tight manner in the vertical direction. A box-shaped cylinder section 6 into which the gate section 5 is inserted is provided on a lower side wall of the notch section 4, and the lower end of the cylinder section 6 reaches the bottom of the bathtub 1.

The side surface of the cylinder portion 6 and the side surface of the notch portion 4 which are opposed to each other in the longitudinal direction of the bathtub 1 are vertically continuous with each other, and a guide groove 7 is formed in the continuous portion along the vertical direction. I have. When the gate portion 5 slides in the vertical direction, both side portions of the gate portion 5 in the longitudinal direction of the bathtub 1 are guided by the guide grooves 7.

As shown in FIG. 2, the gate 5 is provided with a bathtub 1.
A head portion 8 having substantially the same width as the side wall of the notch portion, and an insertion portion 10 extending downward from the head portion 8 and inserted into the cylinder portion 6 through an insertion hole 9 formed at the bottom of the cutout portion 4. . The inside of the head 8 and the insertion portion 10 communicate with each other, and an opening 12 that is opened and closed by an opening and closing door 11 is formed in a wall of the head 8 inside the bathtub 1. Here, in this embodiment, the opening and closing door 11 and the opening 12 constitute the opening and closing valve of the present invention.

An opening 13 is formed at the bottom of the insertion portion 10, and the lower end of the insertion portion 10 is liquid-tight with respect to the inner wall surface of the cylinder portion 6 when the gate portion 5 slides up and down. A sliding piston 14 is provided. A water port 15 for communicating the cylinder portion 6 with the inside of the bathtub 1 is provided below the bottom opening portion 13 of the insertion portion 10 in a wall portion of the cylinder portion 6 inside the bathtub 1.

In the bathtub 1 having such a configuration, when entering the bathtub 1, the opening / closing door 11 of the head 8 of the gate portion 5 is opened with the notch 4 closed by the gate portion 5. In this state, the air in the head 8 can be exhausted from the opening 12, and in this state, when the gate 5 is pushed downward by hand or the like, the gate 5 descends along the guide groove 7. The notch 4 is opened, and the state shown in FIG. 2 is obtained. Thus, even the elderly, handicapped, or infant, etc., the foot can be stably and comfortably inserted into the bathtub 1 from the cutout portion 4 opened across the lowered gate portion 5.

Next, the opening / closing door 11 of the head 8 of the gate section 5
When the bath is closed in this state, the surface of the body rises and the water pressure of the hot water flowing into the cylinder part 6 from the water inlet 15 causes the piston 14 of the gate part 5 to rise. , The gate 5 is automatically raised, whereby the notch 4 is closed, resulting in the state shown in FIG. Therefore, the bath surface at the time of bathing is at the same level as the bath surface of the conventional bathtub, and the bath can be bathed without discomfort.

[0018] When leaving the bath 1, from the rise gate - the air in the head portion 8 close door 11 to open the head 8 of the isolation portion 5 from the opening 12 allows exhaust gate in this state When the gate portion 5 is pushed downward by hand or the like, the gate portion 5 descends along the guide groove 7 and the notch portion 4 is opened, and the state shown in FIG. 2 is obtained. As a result, even the elderly, handicapped, or infant can straddle the lowered gate portion 5 from inside the bathtub 1 and easily put out their feet in a stable state.

Further, aprons stearyl - when bath using di 3, similarly the gate when out in the bathtub 1 - by previously low comb press and part 5 downwards,
Sit on the apron stage 3 and put your body about 1 /
When rotating three times, the foot can be easily moved in and out of the bathtub 1 from the opened notch 4 while keeping the foot in a V-shape state in a stable state, which is particularly suitable for severely ill patients. Can be .
