JPH10248740A - Small-sized bathtub capable of taking upward posture - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a small-sized bathtub capable of bathing at fixed water level and hot water temperature for a long time in a stable upward posture. SOLUTION: This bathtub 1 is provided with a body part movable plate 2, a thigh part movable plate 3, a lower limb part movable plate 4 and a headrest 5. Also, on a bathtub bottom surface and a side face, a mechanism capable of arbitrarily adjusting the water level of the bathtub is provided. Thus, regardless of the size of the physique of a bather, the stable upward posture is taken and bathing is performed at an appropriate water level. Also, since hot water is continuously supplied to the bathtub while maintaining the water level of the hot water at an optional height, bathing for a long time at the fixed hot water temperature is made possible.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small bathtub which can take a back posture when bathing and can bathe for a long time at a constant water level and hot water temperature.

[0002]

2. Description of the Related Art Conventional small bathtubs do not have a device for supporting a bather's body in response to a change in bathing posture of the bather. Further, there was no mechanism for keeping the water level in the bathtub at an arbitrary level while continuing to supply hot water.

[0003]

In a conventional small bath,
He was unable to bathe fully extended, in a stable supine position, and completely relaxed.
Therefore, if you sleep a little in a conventional bathtub, the temperature of the hot water drops and you catch a cold, or the posture of the bather collapses and you may even drown. In addition, it was not possible to take a bath at an arbitrary water level while continuing to supply hot water. The present invention has been made to solve these disadvantages.

[0004]

A movable body plate (2), a movable thigh plate (3) and a movable lower limb portion (4) are provided in a bathtub (1) about the height of a bather. . In addition, a headrest (5) that can be fixed at an arbitrary position is provided. In addition, a water intake (21), a conduit (22), a bellows (23), a conduit (25), and a water level adjusting bracket (27) are provided on the bottom and side surfaces of the bathtub. The present invention is a small tub having the above configuration and capable of taking a supine posture.

[0005]

Embodiments of the present invention will be described below. (A) A body movable plate (2) and a thigh movable plate (3) are placed in a bathtub (1) approximately the height of a bather and shaped as shown in FIG.
And a lower limb movable plate (4) and a headrest (5). The body movable plate (2) and the thigh movable plate (3) are connected by a hinge. A wheel (6) is provided at a part of the body part movable plate and the thigh part movable plate which are connected by a hinge. A wheel (7) is provided at the other end of the thigh movable plate. Wheels (8) and (9) are provided at both ends of the lower limb movable plate.
When viewed from the bather, a pair of wheels is provided on each side. Therefore, a total of eight wheels are provided. The trajectory (10), the trajectory (11), the trajectory (12), and the trajectory (13) through which the respective wheels pass are provided on the left and right inner side surfaces (as viewed from a bather) of the bathtub (1). Each track is a recess on the inside surface of the bathtub. The wheels of each movable plate travel on each track and are released from the track at the top of each track. Therefore, each movable plate can be removed in the upper direction of the bathtub, and the bathtub can be easily cleaned. A handrail (14) is provided on the thigh movable plate (3) so that a bather in a supine position can easily get up. (B) A headrest (5) shaped as shown in FIG. 3 is placed on the bathtub (1) or the body movable plate (2). The bottom surface of the headrest (5) and the surfaces of the bathtub (1) and the body movable plate (2) near the place where the headrest is to be placed are wavy, so that the headrest does not slide down even if it is placed at any position up, down, left and right. To The upper part of the headrest that supports the bather's head is made of a soft material to softly support the bather's head. The lower part (bottom part) of the headrest is made of a relatively hard material so as to be stably joined to the wavy bathtub. FIG. 3 shows a case where the headrest (5) is left at the top. FIG. 4 shows a case where the headrest (5) is set at a relatively low position. The headrest (5) incorporates a waterproof timer and an alarm. The headrest activates a timer in response to the pressure exerted by the bather's head, and sounds an alarm at a preset time (for example, every 10 minutes). (C) As shown in FIG. 5, a mechanism for arbitrarily maintaining the water level is provided on the bottom and side surfaces of the bathtub (1). The hot water flowing from the water intake (21) reaches the bellows (23) via the conduit (22). The upper end (24) of the bellows is open, and hot water is supplied to the upper end (2).
4) More overflowing. The overflowing hot water passes through the conduit (25),
It joins the drain pipe (26) and is drained. Upper end of bellows (2
4) is connected to the water level adjusting bracket (27), and the upper end (24) of the bellows moves up and down by moving the water level adjusting bracket (27) up and down. Therefore, the water level of the bathtub does not exceed the height of the water level adjusting bracket (27). The water level adjusting fitting (27) is a fitting that can be fixed to a position at an arbitrary height on the outer surface (28) of the bathtub. Water level adjustment bracket (2
In 7), a reference line indicating the water level is displayed, and a scale as a guide of the water level is displayed on the outer surface of the fixed bathtub. In addition,
The water intake (21) is plugged in order not to activate the mechanism for keeping the water level constant. The present invention has the above configuration. When using the present invention to take a bath in a supine position, pull up the tip portion (wheel (7) portion) of the thigh movable plate (3) upward and continue forward (toward the bather's lower limb). , The thigh movable plate (3) and the body movable plate (2) move to a position for taking a supine posture and are fixed. Next, the lower limb moving plate (4) is pulled up, moved and fixed. Next, the headrest (5) is set at an appropriate position, and the bather takes a bathing posture while lying on his back. Adjustment of water level, water level adjustment bracket (27)
Is fixed at a position of an arbitrary height and by hot water supply or the like. When taking a bathing posture that is not lying on the back, each movable plate provided in the bathtub is pushed down to take a bath as shown in FIG.

[0006]

The following effects can be expected by using the present invention. (A) If the present invention is introduced as a bathtub for a general household, even if the bathtub is a household bathtub having a limited size, by adjusting the position of the headrest and the water level, the person can lie on his / her back at an appropriate water level regardless of the physique. It is possible to take a bath while taking the posture, and the bather can completely relax. (B) When taking a supine posture, the amount of hot water (water level) needs to be finely adjusted, but this can be easily achieved by the mechanism for keeping the water level constant according to the present invention. (C) If the mechanism that keeps the water level constant works and hot water with a temperature slightly higher than the temperature in the bath tub is continuously supplied to the bath tub, clean hot water is supplied and the hot water at the bottom of the bath tub is relatively low. Since the water is discharged, it is possible to take a long bath with the water level and the hot water temperature kept constant. (D) Even if the user falls asleep in the bathtub, the alarm built into the headrest wakes the user and does not fall asleep.
