Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to a special bathtub for bathing physically disabled persons, physically disabled persons, bedridden elderly people, patients, etc. (hereinafter referred to as physically disabled persons, etc.). In order to raise and lower both the main body and the middle frame that receives the bather in the bathtub, a double-action hood structure is adopted for the drive system, giving the bather a sense of security. At the same time, this was done to reduce the workload of nurses.

``Problems with the prior art'' Normally, when a person with physical disabilities takes a bath, the bather is placed on a stretcher installed on a transport trolley (hereinafter referred to as a stretcher), carried into the bathroom, and bathed on a stretcher. (
After fixing the stretcher in place, the stretcher is moved to a middle frame provided in the bathtub to transfer the bather, and then the middle frame is lowered to allow the bather to take a bath. still,
At this time, as a matter of course, the bather's body is immersed in the bathwater, but appropriate measures such as stretchers, bathtubs, etc. are taken to prevent the bather's face from being submerged. In these conventional special bathtubs, the middle frame attached to the bathtub, that is, the stretcher holder, must be moved up and down by a predetermined stroke via an actuator such as a hydraulic cylinder. As a result, the size of the bathtub body, especially the height of the Japanese cypress, has been determined to be high, and it has been impossible to lower it below a certain value.

On the other hand, for people with physical disabilities, the lower the ground clearance, the more secure they will feel when being transferred from a stretcher to a bathtub or from a bathtub to a stretcher via a stretcher.

From this point of view, conventional bathtubs are not only unfavorable for bathers, but also require caregivers to perform nursing care work from a relatively high position, which is not necessarily favorable in terms of physical fatigue.

Furthermore, there were inherent structural problems in that the middle frame and stretcher lacked stability.

``Object of the present invention'' The present invention provides a useful and suitable special bathtub that solves the above-mentioned conventional problems at once by using a double-action type bathtub that raises and lowers both the inner frame and the bathtub body reciprocally. It provides:

"Structure of the Invention" The special bathtub of the present invention is divided into two parts, a fixed tank and a movable tank, and the movable tank is placed on a first Pandagraph attached to the fixed tank, while the middle frame is raised and lowered in the movable tank. A second pandagraph is installed, and the two pandagraphs are connected by a swinging shaft that moves up and down the two pandagraphs reciprocally, and a swinging lever that drives this, and the second pandagraph is connected to the first pandagraph. is connected to seven actuators such as hydraulic cylinders.

``Example'' A special bathtub according to the present invention will be described below based on an example shown in the accompanying drawings. FIG. 1 is a perspective view showing a schematic configuration of the present invention, in which the bathtub body and stretcher are designated by symbols B and S, respectively. The main constituent members of the bathtub body B are a fixed tank 1a installed on the floor F, and a first pandagraph mechanism Pl attached to this fixed tank 1aK.

Movable tank t supported by first pandagraph mechanism P1
b. A second pandagraph mechanism P2 provided in this movable tank 1b and a 1 mounted on the second pandagraph mechanism P2.
It consists of a middle frame 2 etc. that is rubbed. Further, the stretcher S is equipped with a stretcher 3, and this stretcher 3 has guide rails 4 and 5 so that it can be easily carried into or out of the bathtub from the stretcher side or from the bathtub to the stretcher by a push operation by a nurse. These are provided on the stretcher S and the middle frame 2, respectively. Next, the structure of each part will be explained with reference to detailed sectional views shown in FIG. 2 and below. A hydraulic unit 6 driven by a motor (not shown) is provided at the left end (as viewed from the drawing) of the fixed tank Ia.

A hydraulic cylinder 7 operated by this hydraulic unit 6 has a telescopic rod 8 connected to a first pandagraph mechanism P1 as shown in FIG.
The other end is rotatably supported by a stay (not shown) by a pin 10. Further, rails 11 are laid parallel to each other on both sides in the longitudinal direction of the fixed tank 1a, and one of the pair of rollers 13 guided by the rails 11 is pivotally connected to the link 12 of the first pantograph mechanism P1. The other roller 15 is pivotally attached to one end of the swing lever 14. Both links 9 and 12 are connected to each other by a pivot 16, one end of the link 9 is attached to a stay 18 via a pin 17, and the other end is a long hole guide 19a of a frame 19 attached to the lower surface of the movable tank 1b. is engaged with via roller 20.

The other end of the link 12, which has the roller 13 at one end, is attached near the left end of the frame 19 via a pin 21.

Since the first pantograph mechanism P1 is placed on the fixed tank la and supports the movable tank 1b on the upper part, the movable tank 1
b is configured to move up and down. On the other hand, the second pandagraph mechanism P2 provided in the movable tank lb has the same configuration as the first pandagraph mechanism P1. One of the pair of links 23 is connected to a boss 24a that is firmly fitted to the center of a swinging shaft 24 that extends through the left side of the movable tank lb at right angles to the longitudinal direction. Roller 2
5 is engaged with the elongated hole 26 of the middle frame 2. The above-mentioned swing shaft 24
is rotatably supported by bearings 27, 27 on the frame body 19, and airtightness between it and the movable tank m is maintained by seal members 28 and 28. One side of the other link 29 is pivotally supported by a bin 30 on the left side of the middle frame 2, and the other end is connected to the top of the frame 19 via a roller 31 (movable tank lb).
It can slide while being guided by a rail (parallel to the rail 11) 32 fixed to the inside). The two links 23, 29 are connected to each other by a pivot 33.

The two pantograph mechanisms PI and P2 are connected by engaging the rail 11 with a roller 15 provided at the free end of a swing lever 14 fitted on both ends of a swing shaft 24.

With the above connection configuration, when the hydraulic cylinder 7 extends the telescopic rod 8, the first pantograph mechanism P1 extends as shown in FIG. As it rotates, the swing shaft 24 integrated therewith is also rotated clockwise, performing a reciprocal movement of lowering and contracting the second pantograph mechanism P2 that supports the middle frame 2. That is, when the telescopic rod 8 is retracted, the first pandagraph mechanism P1 is folded and the movable tank 1b is lowered as shown in FIG. The mechanism P2 is extended, and the middle frame 2 provided at the upper part of the mechanism P2 moves upward.

As mentioned above, the movable tank 1b moves up and down in opposition to the up-and-down movement of the middle frame, so when changing the stretcher 3 from the bathtub to the stretcher S or from the stretcher to the bathtub, the movable tank 1b is located at a low height and Since the middle frame is in a high position (lower than the conventional type), it is easy for the caregiver to operate the stretcher, and the middle frame and stretcher are also in a low position, providing good stability. When the stretcher is put into the bathtub by the lowering movement of the middle frame, the movable tank moves upward at the same time even if the stretcher is moving slowly down, so the raising and lowering movement of the middle frame is completed in a relatively short time, and the stretcher is placed in the bathtub. To enable a person with physical disabilities to quickly take a bath without making them feel uneasy.

"Effects" Since the special bathtub of the present invention is constructed as described above, the stretcher, which is located at a relatively low position on the stretcher, can be carried into the middle frame above the bathtub with its momme in a low state, and then carried out and removed. Compared to conventional models, this system completely eliminates the patient's sense of fear due to the high stretcher position, and also reduces the physical fatigue of caregivers and provides good operability. In addition, since the inner frame on which the stretcher is attached and the bathtub move up and down reciprocally, even with slow stretcher movements, the stretcher can be immersed in the bathtub in a short time, giving the patient a sense of security and relaxing bathing. It has the effect of making it possible. Furthermore, since there is only one drive source, the special bathtub is mechanically low-cost and has fewer breakdowns, and the middle frame moves the movable tank to a lower position, improving the stability of the special bathtub. It has many effects, such as a low letcher.
