[Industrial applications]

 The present invention relates to an elevating platform device for a bathtub for facilitating the bathing of a physically handicapped person or an elderly person.

[0002]

[Problems to be Solved by Prior Art and Invention]

 Generally, when a disabled person or an elderly person who has difficulty in bathing alone takes a bath, assistance from a caregiver is necessary, but at this time, a person with a physical disability must be lifted. Therefore, it requires a great deal of effort for the caregiver. Therefore, in order to allow a physically handicapped person to easily enter and leave the bathtub, conventionally, as shown in FIG. 9, a traveling rail 25 provided on the ceiling portion is provided with a freely movable lift 26, or as shown in FIG. As shown in the figure, there is a crane type in which a swing arm 28 that can swing freely to the left and right is provided on a column 27 that stands upright from the floor, and a lift 29 is attached to the swing arm. However, with the former type, the ceiling must be strong enough to withstand the loads of lifts and people, and the ceiling must be reinforced. On the other hand, the latter requires a bathroom with enough space for the swinging arm to swing in an arc, and in either case, it cannot be easily installed in the existing bathroom, and There was a problem that the assistance of a caregiver was still needed to get the disabled person on and off the lift.

On one side of the supporting frame 5, a case 7 is provided which houses a winding device 6 which will be described later. Further, 8 is a quadrangular plate-shaped pedestal that moves up and down in the bathtub 1 as will be described later, but this pedestal 8 has a mesh shape and is used when moving up and down in the bathtub 1. It is designed so that the up-and-down movement of 8 is not hindered by water, but for this reason, the pedestal 8 is not a blind plate type, and, for example, a cage-shaped one, a lattice-shaped one, and pores are Various materials such as a plate-shaped material having a large number of holes can be adopted. On the other hand, at the four corners of the pedestal 8, the tips of four suspension belts (corresponding to the suspension of the present invention, other than the belt, suitable suspensions such as ropes, chains, etc. can be adopted) 9 are respectively provided. It is attached and detached by itself. Of these hanging belts 9, the two hanging belts 9 on the side opposite to the side on which the case 7 is provided have a first supporting roller 10 rotatably attached to the supporting frame 5 on the side. After that, it passes through the inside of the support frame 5 to reach the inside of the case 7, and is further wound around a winding drum 12 described later through a second support roller 11 rotatably mounted in the case 7. On the other hand, the two suspension belts 9 on the side where the case 7 is provided reach the inside of the case 7 as they are, and then pass through the third support roller 13 rotatably mounted in the case 7 and then to the winding drum 12. It is becoming wound.

On the other hand, 14 is an electric motor which constitutes the winding device 6, and an output shaft 14a of the electric motor 14 is provided with a drive side sprocket 15 which rotates integrally with the output shaft 14a. There is. Reference numeral 16 denotes a winding shaft, and an endless chain 18 is suspended between a driven side sprocket 17 attached to the winding shaft 16 so as to rotate integrally with the driving side sprocket 15. The winding shaft 16 is configured to rotate in the forward and reverse directions as the electric motor 14 is driven in the forward and reverse directions. Further, for convenience, four winding drums 12 are attached to each of the two ends of the winding shaft 16 such that two winding drums are provided at each end, and these four winding drums 12 are attached to the winding drums 12. Rult 9 is suspended. Then, the suspension belt 9 is wound around the winding drum 12 and rewound based on the forward and reverse rotations of the winding shaft 16 that accompanies the drive of the electric motor 14, whereby the pedestal 8 is moved inside the bathtub 1. In this case, the gantry 8 is adapted to move up and down while maintaining a substantially horizontal position. Reference numerals 19 and 20 are limit switches for detecting the upper and lower limits of the gantry 8, and are set so that the motor is stopped when the limit switches 19 and 20 are detected. Further, reference numerals 21, 22, 23 are operation switches for raising, lowering, and stopping the gantry. These operation switches 21, 22, 23 are provided in the case 7 in this embodiment, but they are A remote control system that employs wireless means such as radio waves may be used. By the way, the wiring diagram of these switches is shown in Fig. 7, where ES is the emergency stop switch, RSU is the ascending relay switch and its switch contact, RSD is the descending relay switch and its switch contact, and B is the motor brake. Is. It goes without saying that the electric system inside and outside the case 7 is designed to be waterproof.

In the embodiment of the present invention configured as described above, when a person tries to take a bath, first, the gantry 8 is placed at the upper limit position, that is, the position of the upper surface 1a of the peripheral wall of the bathtub 1, and this state is set. A person gets on the pedestal 8. Then, when the lowering operation switch 22 is turned on, the electric motor 14 is driven to lower until the gantry 8 reaches the lower limit position, whereby a person can automatically enter the bathtub 1. On the other hand, when moving up from the bathtub 1, when the raising operation switch 21 is turned on, the electric motor 14 is driven to rise until the gantry 8 reaches the upper limit position, whereby a person can automatically leave the bathtub 1. You can

As described above, according to the present invention, many persons with disabilities can easily enter and leave the bathtub 1 by using the gantry 8 that automatically moves up and down in the bathtub 1. It is possible to take a bath without a caregiver. Even if a caregiver is needed, the labor will be significantly reduced. Moreover, since the lifting platform device for the bathtub 1 is constructed as a retrofit installed so as to be supported on the upper surface 1a of the peripheral wall of the bathtub 1, for example, like a conventional overhead traveling lift or crane type, There is no need to reinforce the site ceiling from the foundation or to require a large area, and it can be installed almost as is in existing ones, and it can be provided at low cost.

It should be noted that the present invention is not limited to the above-described embodiment, and the mount is not a flat plate but a seated one as shown in FIG. 8 (A). As shown in FIG. 8 (B), various shapes such as those with an inclined backrest can be used. Furthermore, guide rails hanging from the support frame may be provided at the four corners of the bathtub, and the guide rails may guide the gantry to guide up and down movements. If a guide member that fits into the guide rail is provided in a protruding manner and a stopper for removing it from the guide rail is provided on the guide member, it is not possible to swing the gantry, and people move to the corners of the gantry. It is possible to prevent the stability of the mount from being impaired when a biased load is applied to the mount. Furthermore, the hanging body is not necessarily located at the four corners of the bathtub, but may be located midway depending on the size relationship between the bathtub and the support frame, and any of these may be provided. Further, as the winding device for winding the hanging body, a spring body such as a constant load spring that constantly exerts a constant winding force or a coil spring that stores energy when the mount is lowered can be used.
