The rotational force of the motor 16 is transmitted to the roller 13a by the toothed belt 17, and the rotational force is transmitted to the other rollers 13, 13
It is converted into the moving force of the endless seat 14 supported together with the mattress 15 from above the endless seat 14.
Patients sleeping in the room are transferred to the side as they are. At the same time, the rotational force of the motor 16 is transmitted to the gear 18a by the toothed belt 19 and rotates the gear 18b.

Further, as shown in FIG. 2, the sheet 4 is preferably attached to the endless sheet 14 by using the magic tape 5 so that the sheet 4 can be moved together with the sheet.

The bed 1 shown in FIG. 3 is provided with a tension roller 13b so that the endless sheet 14 is tensioned only during the transfer, and the tension roller 13b is used to relieve the feeling of discomfort due to the presence of the tensioned endless sheet 14 and the tension roller 13b. Although not shown in the drawing, the actuating mechanism for moving the 13b up and down may be a lever, a crank or the like which is normally used.

Next, the stretcher 2 has four rollers 23, 23a in parallel on the upper and lower sides of the frame 22 fixed over the headboard 20 and the footboard 21. Both ends of these rollers 23, 23a are connected to the headboard 2 described above.
0 and a footboard 21 are rotatably supported by bearing members and are arranged on both sides of the frame. Endless seats 24 are attached to the rollers 23 and 23a so as to be movable laterally. There is.

The upper side of the endless sheet 24 is in contact with the upper surface of the mattress 25 laid on the frame 22 located between the rollers so that a patient or the like can lie on the mattress 25.

The movement of the endless seat 24 is performed by the headboard 10
It is performed by a transmission mechanism provided inside. This transmission mechanism is composed of a swingable L-shaped lever 26 supported downward on the shaft end of a lower roller 23a, and a gear 27 provided at the lower end thereof.
And a toothed belt 28 mounted over the gear 27 and the shaft end of the roller 23a, the rotational force transmitted by the meshing between the gear 27 and the gear 18b on the bed side is rolled by the toothed belt 28. 23a,
As in the case of the bed 1, the endless seat 24 is moved laterally.

The upper arm 26a of the lever 26 is always provided with the lever 26
A spring member 30 is attached to press the brake plate 29 outwardly and press the brake plate 29 attached to the lower end of the upper arm 26 to the lower upper surface of the endless seat 24.

The sliding resistance between the endless sheets 14 and 24 and the mattresses 15 and 25 during the movement of the endless sheets 14 and 24 has a teflon-finished upper surface of the mattress or the endless seat 1
This can be reduced by attaching a Teflon tape to the back surface of 4, 24, and both may be applied if necessary.

FIG. 4 is an explanatory diagram for transferring the patient 6 from the bed 1 to the stretcher 2, and the work begins by laying the stretcher 2 sideways at a predetermined position on the bed 1.

Next, the stretcher 2 is attached horizontally, and the gear 18 on the bed side is attached.
After the gear 27 on the stretcher side is pressed against b and completely meshed, the bed 1 and the stretcher 2 are mechanically connected and integrated. On the stretcher side, the lever 26 is resisted against the spring member 30 due to the mutual pressing of the gears.
Is pushed in, the upper arm 26a moves upward and the brake plate 2
9 is separated from the lower upper surface of the endless seat 24, and the brake is released.

When the motor 16 is driven in this state and the belt 17 is rotated in the counterclockwise direction, the roller 13a is rotated to move the endless seat 14 in the same direction, and the patient 6 on the mattress 15 is moved to the stretcher 2. Transfer to

At the same time, the rotational force of the motor 16 is reduced by the belt 19 and the gear 1
8a, 18b is transmitted to the gear 27 and the belt 28
The rotation of the roller 23a causes the endless sheet 24 to move. The endless seat 24 is moved in the same direction as the bed side by the interposition of the gear 18b to receive the patient 6 transferred from the bed side and transfer it from the side onto the mattress 25.

When the patient 6 is transferred to the predetermined position of the stretcher 2, the motor 16 is stopped to disconnect the both. When the stretcher 2 is released from the bed 1, the upper arm 26 of the lever 26 is pulled back by the spring member 30, and the brake plate 29 presses the lower upper surface of the endless seat 24, preventing the endless seat 24 from moving.

When the sheets are replaced after the patient is moved, the sheets are on the lower side due to the movement, so one of the sheets fixed with Velcro is peeled off, the endless sheet is removed while rotating, and a new sheet is used. This can be easily done by attaching it to one end of the tape and rotating the endless sheet to attach it to the velcro tape on the opposite side.

Although the above embodiment uses four rollers, the number of rollers may be two, and in this case, the rollers have a large diameter. Although the motor 16 is provided on the bed side, the motor 16 may be provided on the stretcher side.

[Advantage of the Invention] As described above, the present invention has a plurality of rollers arranged in parallel on both sides of the frame and an upper surface of the mattress on the frame which is movably mounted over the rollers and whose upper side is located between the rollers. A device for transferring patients, etc. in a bed and a stretcher is composed of an endless seat that moves laterally, and the endless seat can be moved laterally by driving a motor to transfer patients, etc. while lying down.
