Abstract

PURPOSE:To facilitate the getting in/out of a bath tub by rotatably providing two driving shafts through the vicinity of the inner bottom of a bath tub body, linking a lifting up/down mechanism of a human-body supporting member such as a bed, etc., by means of a link mechanism to the driving shafts, and providing a lifting pedal and a lowering pedal. CONSTITUTION:An arm 2a is shifted toward a bath tub body 1 while steppingly applying a foot pressure to a first pedal 2. As the locking of the arm 2a is released from a lock point 18a, a bed 24 is lowered by its own weight in the bath tub body 1 while the arm 2a is lifted up to be locked at an upper lock point 18b. At this time, the sudden lowering of the bed 24 is prevented due to a buffer 20 and the load of a helper's foot applied to the first pedal 2. Then, by releasing the foot, as the arm 2a is released while retaining by hand from the lock point 18b, the bed 24 is further lowered sinking to a deeper position. At this time, a rod 14 is retained by a supporting rod 7 causing a pedal 4 to be automatically lifted up. The bed 24 is bent at a hinge 26 portion and the side on which a pillow 25 is provided is supported by the inner wall of the bath tub body 1 to be utilized as a back.

[Problem to be solved by the invention]

However, even in the above-mentioned bathing device, improvements are required to meet actual needs.

The first is people with mild physical disabilities or those in the rehabilitation process.
Another option is to make the device itself smaller and lower in height, targeting people receiving medical treatment at home.

The second requirement is that it can be operated even by a single nurse.

Furthermore, for patients with residual function, there is a demand for a device that is in the form of a bathtub that people can take a bath in, and that provides an opportunity for rehabilitation while bathing.

The problem to be solved by the present invention is to further improve the above-mentioned previously applied bathing device to make it easier to get in and out of the bathtub, and to save space in the front and rear by arranging the pedals for lifting and lowering on the side. It can be installed in a small space, and if a nurse is needed, it can be done by one person, and it can be used by a wide range of patients, from healthy people to bedridden people, in general homes. The goal is to provide products at low prices.

In addition, 20 is a gas manifold installed outside the bathtub body construction. The bed 2 is operated in conjunction with an actuating arm 2b whose one end is fixed to the drive shaft 6.
4. When descending, prevent sudden descent from the top,
When ascending, it acts as an auxiliary booster, reducing the pressure on the pedals and facilitating smooth operation.

During periods of non-use, as shown in Figures 4 and 5,
The arm 2a of the first pedal 2 is engaged with the lowest lock point 18a of the lock plate 18 and locked. In this state, the bed 24 has rods 9, 10, 11, 12, .
22. Note that since the bed 24 is located on the upper side of the bathtub body 1, it can also be used as a lid.

The operation of the bathing device having the above configuration is as follows.

When a person takes a bath, first, the first pedal 2 and the lock plate 18 are unlocked in the state shown in FIG. This is done by shifting the arm 2a toward the bathtub body 1 while applying foot pressure to the first pedal 2, as shown in FIG.

By releasing the lock from the lock point 18a of the arm 2a,
The bed 24 descends within the bathtub body 1 due to its own weight, and the arm 2a rises and is locked at the upper locking point 18b, resulting in the state shown in FIG. 6. At this time, the load of the assistant's foot applied to the shock absorber 20 and the first pedal 2 prevents the ped 24 from descending rapidly.

Next, remove the legs and move the arm 2 from the state shown in Figure 6.
When the lock a is released from the lock point 18b by slightly pressing it with the hand, the bed 24 further descends and sinks to a deep position as shown in FIG. At this time, the pedal 4 is automatically raised by the rod 14 being pressed by the support rod 7. In addition, the bed 24 is
It is bent at a hinge 261iB, and the side on which the pillow 25 is provided is supported by the inner wall of the bathtub body l and can be used as a backrest.

In this way, by unlocking the first pedal 2, the bed 2
4 descends into the bathtub body l, allowing a person to take a bath with the person inside. Further, when sinking the ped 24, it can be lowered gently by the resistance and buoyancy exerted by the hot water.

Next, in order to return the bed 24 from the state shown in FIG. 7 to the original position shown in FIG. 4, the second pedal 4 is first depressed. As a result, the arm 4b interlocks with the connecting rod 4c and the arm 4d, thereby rotating the drive shaft 5 clockwise. As a result, the rod 14 connected to the drive shaft 5 rotates clockwise while contacting the support rod 7, pushing the support rod 7 up to an intermediate position. At this time, the first pedal 2 descends to a position where it is easy to step according to the movement of the support rod 7, and the upper locking point 1
8b (Fig. 6). Next, the first pedal 2 is depressed from the state shown in FIG. 3, the arm 2a is locked at the lower locking point 18a, and the bed 24 is set to its original position (FIG. 4).

As mentioned above, the first. Since the second pedals 2 and 4 are integrated on one side of the bathtub body 1, the patient can be easily bathed by two caregivers. In addition, as the bed 24 is positioned like the lid of the bathtub body 1, as shown in Figure 3, the patient can easily climb onto the bed using his/her own blade and take any position by simply sitting on the bed 24. . Therefore, regardless of the degree of disability, it is possible to take a bath easily. Further, since the bed 24 can be set in a flat shape as shown in FIG. 1, the upper surface of the bed 24 can be used for bending and stretching exercises during bathing, which is suitable for rehabilitation. Of course, it is also possible to use the bed 24 in a bent position and use it as a backrest when taking a bath.

Regarding the bathing device of the present invention, the pedal depression load when raising the bed 24 is approximately 2.5 times the ratio of the raising stroke of the bed 24 to the total effective stroke of the second pedal 4 and the first pedal 2. As for the force distribution, when the second pedal 4 is operated, that is, when changing from Fig. 7 to Fig. 6, the load is light due to underwater buoyancy, so the pedal force of the second pedal 4 is During the operation of the first pedal 2, that is, when switching from Fig. 5 to Fig. 3, the toggle mechanism of the loft 11 and 12 generates a strong force as it is released underwater, and the gas shock absorber is used. 20 also uses the gas pressure to increase the push-up blade as the bed 24 rises, helping it to rise smoothly, so the pedal load is small, and it can be operated with an average pedal load of about 15 kg to 15 kg, so even a weak household woman can operate it by herself. Can be operated easily. In addition, when the bed 24 is held at the highest point, the rod 11 and the loft 12 are close to a straight line, so the lock point 1
The force applied to locking the bed 8a is also small and the bed 24 can be held stably.

Of course, it is also possible to take a bath with the ped 24 in a bent position and use it as a backrest from the beginning.

Furthermore, according to the present invention, the operation pedal is arranged on the side surface of the bathtub body 1, and the vertical stroke of the pedal can be kept within the height range of the bathtub body 1, so the height of the entire bathing device can be reduced. A link mechanism for raising and lowering the bed 24 can also be provided. Because of this, the patient is in bed 24
It is easy to get into the bathing position, and you can take a bath by yourself without needing a helper. Also, when a healthy person takes a bath, if the bed 24 is kept in a sunken state as shown in Figure 6,
It is similar to a regular Western bath, and you can take a bath without any problems.

〔Effect of the invention〕

As explained above, the bathing device of the present invention does not require any power, has no protrusions around it, can incorporate a lifting mechanism into the same external shape and dimensions as a general bathtub, and has a simple structure. Because of this, there is no need to worry about breakdowns, and it can be provided at a low price, so it is suitable for hospitals and other facilities.

It can be used anywhere, including at home. In addition, since the patient can take a free position by simply sitting on the bathtub, the patient can perform functional recovery training by making full use of their remaining functions and moving on their own without having to be treated like a bedridden patient.

In addition, the caregiver does not have to hold the patient, making it easier for the caregiver. In addition, since the bathtub itself has a built-in lifting mechanism, there is no need to assemble and install the bathtub each time a patient takes a bath, and it can be used immediately by anyone from healthy people to bedridden people.
