Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to the upper and lower parts of a movable sleeping bathtub vehicle that can serve as both a bed and a bathtub for the elderly and disabled persons (hereinafter referred to as disabled persons) to carry disabled persons up and down. This relates to the Jj1 descending device.

[Conventional technology]

Conventional mobile sleeper bathtubs have a hanging lift attached to the main body to raise and lower a disabled person into the bathtub or to lie down on a bed.

For this reason, there is a problem in that an installation space including the lift is required, and if the lift breaks down, a disabled person or the like becomes stranded in the air, making it impossible to take immediate emergency measures.

[Problem that the invention seeks to solve]

The present invention has been made in view of the above points, and it is an object of the present invention to provide a vertical elevating device for a mobile sleeper bathtub vehicle that does not take up much installation space and that allows emergency measures to be taken immediately in the event of a breakdown.

[Means for solving the problem and its operation] The present invention has been made to solve the above problem.
A lower plate 4 that can be moved up and down in the bathtub, a guide rod 5 provided at the corner of the two lower plates 4 at several intervals downward in the bathtub 3, and a lower part of the upper and lower plates 4. A water-resistant bearing 6 is installed in the bathtub 3.
, 7, and has a left-hand thread and a right-hand thread carved toward the center of each other, nuts 9 and 10 that are screwed into the left-hand thread and right-hand thread of the shaft, and the nuts 9 and 10. Rings 4a and 4b formed on the back surface of the upper and lower plates 4 on the center side of the nuts 9 and 10 are tilted between rings 4a and 4b, and both ends of the rings are loosely attached, and the angle of inclination changes as the wheel 118 rotates to record the dance. Lower plate 4
upper and lower rods 11.12 for moving the 4118 vertically;
and a rotating means for rotating the.

Since the above +IC configuration is adopted, the vertical lifting device of the present invention has the following features:
A number of bells are placed inside the bathtub, which saves installation space and allows quick emergency treatment in the event of a breakdown.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a diagram showing the vertical lifting device of the present invention, and FIG. 2 is a plan view.

A rectangular parallelepiped bathtub 3 with hard urethane pasted on it is placed above the moving wheels 1 and 2, and upper and lower plates 4 are placed inside the bathtub 3.
is provided so that it can be made into two parts, and is held upright by 3b.

In the bathtub 3 at the bottom of the upper and lower plates 4, there are several screws 1118 through bearings 6 and 7 which have a water-resistant structure and do not leak water to the outside, and the screws 118 have a left-hand thread 8a and a right-hand thread 8b toward the center. It is engraved.

The left-hand thread 8a and right-hand thread 8b of the shaft 8 are each provided with nuts 9.10 that are movable in the axial direction. Each of the nuts 9 and 10 has a bifurcated end lock 9a.
, IQa are welded a, and the -E lower rods 11, 12 are welded to the back surfaces of the upper and lower plates 4 and are connected to the rings 4a, 4b, respectively, tilting toward the center from the end locks 9a, 10a. It is worn as a stray.

The right end of the shaft 8 is connected to a DC motor 14 via a shaft joint 13. In addition, 15 is a battery,
16 is a charger, and 17 is an earth leakage preventer for safety.

The center portion of the upper and lower plates 4 has 1. A defecation hole 19 and a defecation tank 20 are provided through the bathtub 3, and a drain hole 21 and an exhaust gas ζ plug 22 are provided at the bottom of the bathtub 3.

Also, M8. Nut 9, 1.0, upper and lower rods 11°12
It is desirable to use stainless steel or the like as the material from the viewpoint of rust prevention.

With this configuration, by turning on a switch (not shown) and driving the DC motor 14 to rotate the shaft 8, the nut 9° 10 can be moved closer to the center. Then, the holes in the upper and lower plates 4 are raised 9, and the nuts 9 and 10 are moved closer to the outside of the shaft by reversing them.
The height of the upper and lower plates 4 can be lowered.

Therefore, by raising the height of the upper and lower plates 4, the upper and lower plates 4 can be used as a bed, and by lowering them, the upper and lower plates 4 can also be used as the bottom plate of a bathtub. When changing from a bed to a bathtub, the person with a disability is rolled to the side of the bed without lifting them, undressed and bedding such as underclothes and sheets are removed, lowered the upper and lower boards 4, poured hot water, and changed the bathtub. Since it can be used in a single manner, nurses do not need much effort. Since the trench does not have a structure in which the bathtub is suspended horizontally on a frame like in the past, the shape of the bathtub can be made large, allowing disabled people to take a bath in a relaxed and comfortable posture. Even if the vertical lifting device breaks down,
Unlike conventional lifts, you don't end up stuck in the air, and emergency measures can be taken quickly.

It should be noted that the vertical elevating device of the present invention is not limited to a mobile sleeper bathtub car, and can of course be attached to, for example, an existing bathtub.

C. Effects of the Invention] As explained above and in Section 7, the vertical lifting device of the present invention overcomes the problems of conventionally used lifts. 2. It does not take up much installation space, and when it malfunctions, it becomes suspended in the air like a lift. First aid can be taken quickly without any problems. Also,
The vertical lifting sieve device of the present invention is built into the bathtub and does not have a structure in which the bathtub is hung horizontally on a frame as in the past, so the shape of the bathtub can be made larger and a comfortable posture for disabled people. You can take a bath.
