Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath tub apparatus provided with a stretcher transfer rail for bathing a disabled person or the like who is unable to walk with a stretcher.

[0002]

2. Description of the Related Art Some bathtub devices for bathing persons with physical disabilities such as the elderly and the physically handicapped (hereinafter sometimes referred to as patients) include those in which a patient is bathed on a stretcher. is there. In a bathtub apparatus provided with such a stretcher transfer rail, a stretcher transfer rail is basically provided in the bath. This stretcher transfer rail is
It can be displaced in the vertical direction relative to the bathtub, and can take a high position for transferring a stretcher and a low position for taking a bath (for example, Japanese Patent Laid-Open No. 3-149).
048).

When a patient is to take a bath, the patient is placed on a stretcher on a carrier and transferred to the bathtub, and then the transfer rail on the carrier provided on the carrier is moved to the stretcher on the bathtub at the high position. Aligned with transfer rail. Thereafter, the patient is transferred to the stretcher transfer rail on the bathtub side together with the stretcher. The stretcher transfer rail on the bathtub side on which the patient is placed is lowered relative to the bathtub to be in the low position, whereby the patient is bathed in the bath water. After the end of bathing, the patient is transferred from the bathtub to the transport vehicle together with the stretcher in a procedure reverse to the procedure described above.

[0004]

By the way, when the stretcher transfer rail on the transporting vehicle side and the stretcher transfer rail on the bathtub side are aligned with each other, the conventional one has a considerably large space between both the stretcher transfer rails. A gap was to be formed. That is, since the stretcher transfer rail on the bathtub side is displaced up and down relative to the bathtub, its length, that is, the position of the longitudinal end is on the bathtub inner wall surface so as not to interfere with the bathtub inner wall surface. Is short enough not to reach. On the other hand, since the transfer of the stretcher is performed over the upper edge of the bathtub, if the two stretcher transfer rails are aligned, at least a gap corresponding to the length corresponding to the upper edge of the bathtub. Was to be formed.

[0005] Because of the large gap, a large shock is likely to occur when transferring the stretcher. Also, in order to avoid such a large shock, the nurse must perform the transfer work while supporting the considerable weight of the stretcher on which the patient is riding when going over the large gap, which imposes a burden on the nurse. It will be extremely large.

In order to eliminate the large gap as described above,
It is also conceivable to set the stretcher transfer rail on the transport vehicle side to be sufficiently long, that is, a length that extends beyond the upper edge of the bathtub to near the inner wall surface of the bathtub. However, in this case, the stretcher transfer rail on the carrier side protrudes greatly from the carrier, and cannot be practically adopted.

[0007] The present invention has been made in view of the above circumstances, and its purpose is to align a stretcher transfer rail on a transport vehicle side with a stretcher transfer rail on a bathtub side. It is an object of the present invention to provide a bathtub apparatus provided with a stretcher transfer rail in which a large gap is not formed between the stretcher transfer rails.

[0008]

Means for Solving the Problems In order to achieve the above object, the present invention has the following configuration. That is, in the bathtub, a stretcher transfer rail is provided, and the stretcher transfer rail can be displaced up and down relative to the bathtub, and a high position and a bathing state for transferring the stretcher. In a bathtub apparatus provided with a stretcher transfer rail configured to be able to take a low position, the stretcher transfer rail extends substantially horizontally and does not interfere with the inner wall of the bathtub due to vertical displacement relative to the bathtub. A main body rail set to a length, and an extension rail provided at an end of the main body rail, wherein the extension rail extends substantially horizontally in an extension direction of the main body rail, and extends relative to the bathtub. The storage position is shorter than the extended position so that the vertical displacement can be achieved. Preferred embodiments of the present invention based on the above configuration are as described in Claims 2 and 3 in the claims.

[0009]

According to the first aspect of the present invention, at a high position where the stretcher is transferred, the stretcher transfer rail on the transport vehicle side and the main body rail among the stretcher transfer rails on the bathtub side are disposed. Since the extension rail located at the extension position is present in the large gap portion, the large gap conventionally existed is eliminated, and the transfer of the stretcher can be performed smoothly. After the transfer of the stretcher, by placing the extension rail in the storage position, there is no problem in lowering the stretcher transfer rail on the bathtub side for bathing without interfering with the inner wall surface of the bathtub. Will not be.

With the configuration as described in claim 2, it is possible to switch between the extension position and the storage position by a simple operation of changing the sliding position of the extension rail with respect to the main body rail.

[0011] By adopting the structure as described in claim 3, in response to the case where the stretcher transfer rail on the side of the carrier is located considerably inward from the outer surface of the carrier, The gap between the stretcher transfer rail on the transport vehicle side and the stretcher transfer rail on the bathtub side can be reduced.

[0012] With the configuration as described in claim 4, the extension rail which is in the extension position and receives a large weight during transfer of the stretcher can be firmly supported by the bathtub itself.

[0013] With the configuration as described in claim 5, the transfer of the stretcher can be selectively performed from any direction of each end of the stretcher transfer rail.

Done.

Before or after the carrier 21 is positioned with respect to the bathtub 1, the lifting and lowering device 10 sets the stretcher transfer rail 12 on the bathtub 1 side to the high position shown in FIG. It is a horizontal extension position. In this state, the stretcher transfer rail 23 on the transport vehicle 21 side and the stretcher transfer rail 12 on the bathtub 1 side are in an aligned state positioned on the same straight line. In this aligned state, a large gap is formed between the stretcher transfer rail 23 on the side of the transport vehicle 21 and the main body rail 13 of the bathtub 1, and the extension rail 14 is located in this large gap. (See FIG. 3). That is, the stretcher transfer rail 23 and the main body rail 13 are connected via the extension rail 14 with almost no gap.

From the state of FIG. 3 in which the stretcher transfer rail 23 and the main body rail 13 are connected via the extension rail 14,
The stretcher 31 on the transport vehicle 21 is moved toward the bathtub 1, and the stretcher 31 is transferred onto the main rail 13 of the bathtub 1. At this time, the stretcher 3

Here, it is conceivable to provide an extension rail for the stretcher transfer rail 23 on the side of the transport vehicle 21. However, in view of the fact that the number of carriers 21 is much larger than the number of bathtubs 1, it can be easily understood that it is much more advantageous to provide an extension rail on the stretcher transfer rail on the bathtub 1 side. You.

Although the embodiment has been described above, the present invention is not limited to this and includes, for example, the following case.

(1) The stretcher transfer rail 12 only needs to be displaceable in the vertical direction relative to the bathtub 1. For this purpose, the vertical position of the stretcher transfer rail 12 is fixed, and only the bathtub 1 is moved up and down. It may be displaced in the direction.
Further, as shown in the above-mentioned JP-A-3-149048, both the stretcher transfer rail 12 and the bathtub 1 can be displaced in the vertical direction, and when the stretcher transfer rail 12 is displaced downward, the bathtub 1 moves upward. It may be displaced (so that the bathtub 1 is displaced downward when the stretcher transfer rail 12 is displaced upward). Of course, the drive source for raising and lowering can be appropriately selected such as an electric motor.

(2) The extension rail 14 (54) may be provided only at one end of the main body rail 13 (53). However, as shown in the embodiment, it is better to provide an extension rail for each end of the main body rail,
This is advantageous in that the transport vehicle 21 can be approached from both the left and right sides of the bathtub 1.

(3) A drive source such as a hydraulic cylinder may be separately used to switch the extension rail between the extension position and the storage position. In this case, the drive source may be provided on the main body rail. In addition, the drive source is automatically controlled, and when the stretcher transfer rail is at the high position, the extension position is automatically set to the extended position. The driving may be controlled so as to be performed.

(4) In the embodiment shown in FIGS. 1 to 7, the extension rail 14 is securely extended when it is at a high position in consideration of the swing resistance of the extension rail 14 with respect to the main body rail 13. As described above, a spring that biases toward the extension position may be provided. In this case, the spring urges the extension rail 14 from the storage position shown in FIG. 2 so that the extension rail 14 becomes substantially horizontal. For example, a spiral spring surrounding the pin 15 can be used. (5) A sliding resistance reducing member such as a synthetic resin or the like (inner wall surface 1b) or a cushioning member such as a rubber may be provided on a portion of the bathtub 1 where the extension rail 14 is in contact (upper). Edge 1a). (6) A stopper may be provided for the main rail 13 to restrict the extension rail 14 from swinging further downward from the extended position at which the extension rail 14 is substantially horizontal.
