The shape of the groove 21 in plan view is such that the base end entrance portion is widened and gradually narrowed, the center portion is narrowed, the back portion is widened, and the tip portion is pointed. In other words, the groove 21 is pointed so that the tip of the horizontal frame portion 20 comes into contact with the tip of the groove 21 so that lateral movement is not possible. A cushion 54 having an appropriate thickness is attached to the distal end portion, and the cushion 54 absorbs both impact vibrations when the horizontal frame portion 20 contacts the distal end portion. The inner part of the groove 21 has such a width that the caster 16 attached to the stretcher 6 can swing about the axis of attachment to the horizontal frame 20, that is, the caster 16 is The wide portion 21a is wide enough to be rotatable due to the existence of an eccentric distance at the center of the wheel body. The central portion of the groove 21 nearer to the inner side is formed as a narrow portion 21b having a width slightly larger than the diameter of the horizontal frame portion 2.
Are designed to limit the lateral movement of the horizontal frame 2. . The proximal end entrance of the groove 21 is formed wide so that the distal end of the horizontal frame 2 can be easily applied to the proximal entrance. The side from the base end entrance to the center of the groove 21 is gradually narrowed so as to serve as a guide for the horizontal frame 2 entering the groove 21.

In the above-described groove 21 having a plan view shape, the base entrance portion is wide, so that the horizontal frame portion 20 can be easily fitted to the base end entrance portion of the groove 21, and the both side plates of the groove 21 guide the horizontal frame portion. It is easy to introduce the tip of the part 20 into the inside of the groove, and when the horizontal frame part 20 goes into the back, the center part of the groove 21 has a narrow side plate interval,
Unnecessary lateral movement of the horizontal frame portion 20 is restricted, and the tip of the groove 21 is pointed. Therefore, when the horizontal frame portion 20 is inserted as far as it will go, the tip of the horizontal frame portion 20 becomes As a result, the stretcher 6 is brought into a fixed state by contacting the shape portion, and the position of the stretcher 6 with respect to the bathtub 45 can be accurately determined.

When the stretcher 6 is pulled out of the bathtub 45, the caster 16 swings due to the existence of the eccentric distance. However, the groove 21 has enough room to allow the horizontal movement of the horizontal frame 20 during the swinging. The stretcher 6 is pulled out of the bathtub 45 with the side plate spacing.

The stretcher portion 7 is constructed by stretching a member such as a net or a porous material through which hot and cold water can easily pass. When the bather after bathing is taken out of the bathtub 45, the stretcher 6 is pulled out. Move in the drawer direction. At this time, in order to prevent the hot water adhering to the stretcher portion 7 from being carried out of the bathtub 45 and dripping, the upper edge of the long side portion of the receiving tub 1 is attached to the stretcher portion 7.

[0053]

The present invention is configured as described above, and has the following effects. The conventional shower bath is a multi-person task in which both ends of a stretcher carrying a bather are provided by at least two people, so it requires labor and cost, and an empty stretcher is required to take a bath by one person. Must be locked and set in advance on the handrail rod on the bathtub body side, and on the stretcher, it must be replaced from another stretcher that has carried the bather, so that the burden on the caregiver becomes excessive, There was a risk of falling off at the time of transfer and giving the bather an extra burden and anxiety, but in the easy-to-retract shower bath of the present invention, the bather is placed on a stretcher. The bather can be moved into and out of the bathtub simply by moving the stretcher, so that even one assistant can work with less burden.

Further, since there is no transfer from a stretcher to a stretcher, it is safe and does not give a burden or anxiety to a bather. In addition, since the stretcher portion is not locked and built in the receiving tank, the stretcher portion can be easily removed from the receiving tank, so that the work of removing the stretcher portion having a considerable weight (usually about 30 kg) is unnecessary, and the receiving tank is cleaned. And maintenance is easy.

When the stretcher and the stretcher have an integral structure, when the stretcher is pulled out from the upper part of the receiving tank, water dripping from the stretcher can be removed by the water drop removing device. When the stretcher moves, there is no inconvenience that water drops fall from the stretcher and wet the stretcher passages and floor.

Since the configuration is such that hot water does not fall on the floor, it can be used in a room without waterproof treatment, and the shower bath of the present invention is installed in a room without waterproof treatment. Above is convenient. In addition, even when the waterproofing treatment is performed, it is simple and the cost for the facility is low, and the occurrence of a situation such as water leakage can be prevented.

In the docking operation in which the stretcher is aligned with the receiving tank so that the stretcher reaches the upper part of the receiving tank, a groove for guiding the horizontal frame of the stretcher is provided at the bottom of the receiving tank. The work can be performed accurately and easily within a short period of time, and the bather does not have unnecessary collision vibration and does not cause discomfort.

Further, since the support leg is watertightly surrounded by a notch formed in the edge on the opening / closing end side of the lid, the upper lid is brought into close contact with almost the entire circumference of the receiving tank. Therefore, when the shower is activated, the hot water does not scatter outside the upper lid, and it is convenient for the caregiver to avoid a situation in which the hot water gets wet due to the splashed water during the assistance work. In addition, the presence of the notch and the soft material for watertightness attached to the notch improves the airtightness of the upper lid and the receiving tank, so that low-temperature outside air does not enter the inside of the lid and heats the bather. It does not interfere and is convenient.

In a shower bath having a cutout, the support leg of the stretcher is positioned so as to enter the cutout. Therefore, it is important that the stretcher comes to a predetermined position. With the above-mentioned groove structure, the stretcher can be quickly and accurately docked at a predetermined position so that the support leg can be properly inserted into the cutout portion, which is very convenient.

In the conventional shower bath, if the hot water reaching the nozzle mechanism is not at a temperature suitable for bathing, that is, cold water remaining in the pipeline leading to the nozzle, or hot water supplied from a facility. When the pressure of hot and cold water fluctuates, the hot water or too hot water that transiently comes out of the mixing valve,
In the case of hot water that is generated when the mixing valve breaks, there is a problem that these unsuitable hot waters hang on the bather and give the bather danger, discomfort and anxiety, but in the shower bath of the present invention, Since the hot water that is not at a temperature suitable for bathing is determined by the hot water temperature determination unit and the hot water is drained, the inconvenience of giving the bather danger, discomfort, or anxiety due to cold or hot water occurs. Absent.
