BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a walking training tub used when a person with impaired limb function performs a function recovery training in hot and cold water using its heat, buoyancy and resistance.

[0002]

2. Description of the Related Art A general walking training tub is composed of an exercise tub and a walking tub which are flange-connected to form a walking training tub in which the inside of the tub communicates in series. If necessary, both partial tubs are separated by a partition plate. Many of them are configured so that they can be formed and used.
Japanese Patent Publication No. 354 and Japanese Patent Publication No. 4-63704 are known.

[0003]

In the walking training tub as described above, it is necessary to seal the joint between the two tubs which are flanged to each other so as not to leak hot and cold water. In the training tub, as described in the above-mentioned former publication, the flanges of the both tubs were sealed by fastening and fixing the rubber packing to the mating surfaces thereof, so that there were the following problems.

That is, in the walking training tub as described above, it is unavoidable that a distortion or a twist is generated between the combined bathtubs, and the twist is intensively applied to the flange mating portions of the both bathtubs. Therefore, in the conventional sealing structure in which the rubber packing is sandwiched and fixed between the mating surfaces of the flanges, the rubber packing is apt to be fatigued and easily damaged due to the torsion and the like, and water leakage occurs in a relatively short time. was there.

A conventional walking training tub provided with a partition wall capable of partitioning the inside of the bath tub is operated by manually changing the partition wall between a partitioning position and a partition releasing position, as seen in the above-mentioned latter publication. Therefore, when the partition is operated in a state where hot water is present in the bathtub, a large amount of labor is required.

This labor-consuming point can be solved by configuring the partition body to be automatically operated by power means such as hydraulic pressure, and such a power means can be easily adopted. If the partition is automatically operated by the power means, there is a concern that a bather or other person may be inadvertently positioned in the operating area of the partition and collide with the partition.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances of the prior art, and its object is to automatically operate a partition body capable of partitioning the inside of a tank by a power means. However, it is an object of the present invention to provide a safe walking training tub in which bathers and others are prevented from colliding with a power-operated partition wall.

That is, according to the present invention, a partition wall (8) capable of partitioning the inside of a bath tub in a watertight state is provided so as to be operable to be changed between a partitioning position and a partition releasing position by a power means (9). Alarm device (10) for notifying that (8) is in operation
Is provided. Further, a partition body (8) capable of partitioning the walking bathtub (1) and the entrance / exit bathtub (2) in a watertight state is provided so as to be operable to be changed between a partitioning posture and a partition releasing posture.
One side of the peripheral wall of (2) is a door for bathers to enter and exit (11)
When bathers enter and leave a walking training tub formed by joining a walking training tub (1) and an entrance / exit bath (2), there is no hot water in the entrance / exit tub (2). A walking training tub characterized by opening and closing a door (11).

[0009]

When a bather enters or leaves a walking training tub formed by joining a walking tub 1 and an entering / leaving tub 2, the partitioning body 8 stands up to separate the walking tub 1 from the walking tub 1. The operation is performed by opening and closing the door 11 provided in the bathtub 2 in the absence of hot water. After the bather walks or enters the bathtub 2 while riding on the carrier, the door 11 is closed, and the hot and cold water in the walking bathtub 1 is moved to the bathtub 2 by the hot water moving device 43. Soak in hot water.

Next, when the power means 9 is operated by a switch operation on the operation panel 14 and the partition 8 is turned down to a position along the bottom of the walking tub 1, the entering / leaving tub 2 and the walking tub 1 become a series. When both the bathtubs have hot and cold water, when the partition body 8 is in a predetermined falling state, the falling sensor 34 detects the state and the power means 9 is automatically stopped, and the partition body 8 is moved to a predetermined state. It is maintained in a falling posture.

In the above state, the bather is moved into and out of the bathtub 2.
Is moved to the walking tub 1 from above, and then the partition 8 is erected again. At this time, if the partition 8 is in a predetermined upright state, the upright sensor 35 detects the state and the power means 9 Is automatically stopped, and the partition 8 is kept in a predetermined standing state. After the bathtubs 1 and 2 are separated by the partition 8, the hot water in the entrance / exit bath 2 is walked by the hot water moving device 43. It moves to the bathtub 1 side, the water depth of the walking bathtub 1 is set by adjusting the transfer amount appropriately, and the walking training is performed in the walking bathtub 1.

In the process in which the partition body 8 is moving toward the predetermined turning position and the predetermined standing position, the alarm device 10 informs the user of this fact. The risk of entering or approaching the working area of the body 8 is avoided.

When leaving the bath after walking training,
After a part of the hot and cold water in the walking tub 1 is transferred to the entering / leaving tub 2 by the hot and cold water moving device 43, the power means 9 is operated to turn the partition 8 into a posture along the bottom wall of the walking tub 1. When a carrier is used, the bather moves from the walking bathtub 1 to the bathtub 2 and when the bather finishes riding on the carrier, the partition 8 is raised and the bathtubs 1 and 2 are moved up. The bath 11 is moved again by the hot and cold bath moving device 43, and all the water in the bathtub 2 is moved to the walking bathtub 1 side. In a state where the bathtub 2 is empty, the door 11 is opened and the bather enters. Walking out of the bathtub 2 ends the walking training. In addition, in the case of bathing,
The function of automatically stopping the fixed position of the partition 8 by the lodging / standing sensors 34 and 35 and the function of notifying the movement of the partition 8 by the alarm device 10 function in the same manner as described above.
