When descending, the guide roller 16 of the stretcher support arm 11 first rolls against the guide frame 17, and then rolls against the inner side wall 32 of the bathtub 3. The guide roller 16 supports one end of the stretcher support arm 11.

When rotating the column 5, the stopper 27 is released, and when the column 5 is at the end of rotation and is to be moved up and down, the stopper 27 is applied to fix the rotation of the column 5.

The stretcher 1 rotates on a horizontal plane with the stretcher retaining shaft 19 of the stretcher retainer 18 as the axis.
When rotating the stretcher 1, the stretcher 1 is rotated by the stretcher retaining shaft 19 at any time to adjust the position of the stretcher 1. When sinking the stretcher 1 into the bathtub 3, the stretcher 1 is manually aligned with the bathtub 3, and when setting the stretcher 1 to be lowered outside the bathtub 3, the stretcher 1 is positioned parallel to the bathtub 3, etc., and the stretcher 1 is manually moved as appropriate. adjust.

When the stretcher 1 is moved in parallel when the support 5 is rotated, the configuration is such that the sub support 35 is erected on the base 4, the hanging rod 36 is erected at one end of the stretcher 1, and the support 5 is moved in parallel when the support 5 is rotated. The line connecting the stretcher hanging shaft 19 and the hanging rod 36 is parallel to the line connecting the stretcher hanging shaft 19 and the hanging rod 35.

A sliding bearing 37 is provided at the base end and is fitted onto the sub-pillar 35 so as to freely slide up and down and rotate, and a hanging rod 3 is provided at the other end.
A connecting rod 39 is provided with a bearing 38 that is rotatably fitted to the outside of the auxiliary column 35 and a retaining rod 36. Alternatively, it is also possible to construct the sprocket fixed to the stretcher 1 side and the sprocket fixed to the base 4 side by a chain.

In another embodiment of the present invention, when the support column 5 is rotated electrically, the shaft 2 is suspended and extended from the lower end of the support column 5 into the rotation support part 13 as shown in FIG.
A worm wheel 30 is fitted onto the shaft 9, and a worm 33 fitted onto the shaft of a rotation motor 31 is engaged with the worm wheel 30, and the support column 5 is rotated by rotation of the rotation motor 31.

The effects of the present invention having the above configuration and operation will be described below.

The sliding device is slidably fitted onto the column, and the stretcher support arm fixed to the sliding device is suspended by a hanging rope that extends from the lifting drive unit at the top of the column, which reduces the flatness of the lifting device itself. Furthermore, by providing the elevating device close to the bathtub, the bathing device itself can be housed in a small area. Therefore, it is easy to install this device even in a narrow bathroom, and the bathroom space can be used more effectively. In addition, since the lifting drive unit is installed at a high level, there is no splashing water on the lifting drive unit, which reduces electrical leakage, rust, etc. of the equipment, and reduces the causes of failure of the equipment and extends its service life. Furthermore, the lifting method eliminates the need for heavy steel objects such as conventional hydraulic cylinders and cylinder rods, and allows the device to be made lightweight by using lightweight objects such as slings, reducing the labor involved in transportation, delivery, and installation. did.

Furthermore, guide rollers are provided on the vertical sides of the stretcher support arms, so that when the stretcher support arms are located on the bathtub side, the guide frame and one side wall inside the bathtub are flush with each other, and the stretcher support arms are placed on the outside of the bathtub. When positioned, the guide frame and the fixed guide frame are on the same plane, and the guide rollers are configured to contact and roll against the guide frame, the inner wall of the bathtub, and the fixed guide frame. With this configuration, it is possible to reduce the deflection of the sliding tool and the stretcher support arm, prevent the free end of the stretcher from drooping, and furthermore, it is possible to prevent the stretcher from swinging. As a result, the movement of the stretcher was stable and the patient was able to take a bath with peace of mind.

Furthermore, since the elevating device is installed on the base, there is no need to embed bolts into the floor, making installation of the bathing device and relocation after installation extremely easy.

Furthermore, compared to the conventional method in which a stretcher is raised and lowered by installing an arm protruding horizontally from a support and moving this arm in a fan shape on a vertical plane, the lifting and lowering operation of the stretcher by the device of the present invention allows the stretcher to be moved vertically. Because only the robot is raised and lowered, there is less shaking, reducing anxiety for the patient.
Now I can bathe comfortably.
