The above-mentioned lifting means are already widely known and there are numerous types, so any of them can be applied and will not be described in detail in the present invention.

The operation of the transport device of the present invention configured as described above will be described in detail as follows.

If you want to transport a patient with mobility impairment in bed to the bathroom or a desired location, the seat rotation frame 161 is opened up and down to the left and right as shown in Figure 2. At this time, the seat rotation frame 161 is connected to the vertical lifting frame 130. ) is spread around the two rotating tubes 131.

With the seat rotation frame 161 open as described above, the patient is made to sit on the edge of the bed (B) as shown in FIG. 8, and then the transfer device is brought close to the bed (B). At this time, the bottom frame of the transfer device Since the top of the bed (B) is located between (100) and the seat rotation frame (161), push the transfer device as deep as possible so that the seat rotation frame (161) is positioned on both sides of the patient's hips, and then rotate the seat. The frame 161 is closed around the patient.

When the two seat rotation frames 161 are retracted, the patient's hips are tilted in one direction and the two chairs 163 and 163' are brought closer together. At this time, the two chairs 163 and 163' have an arc shape. Since the toilet grooves 164 and 164' are formed, the two chairs 163 and 163' can be brought close to each other without the patient's buttocks being tilted too far to one side.

Then, since the two seat rotation frames 161 can be opened, the handle 164 on one rear side of the seat rotation frame 161 is moved along one axis with the hinge 160 as the center, as shown in FIGS. 3 and 4. , At this time, the rotating bracket 170 connected to the handle 164 rotates and the fixing groove 171 formed at one end is coupled to the hinge 168 of the other seat rotating frame 161, so that the two seat rotating frames 161 are connected to each other. It can prevent cracking.

When the two seat rotation frames 161 are stably coupled, the chairs 163 and 163' of the two seat rotation frames 161 are in close contact with the upper surface of the bed B, so the transfer device is connected to the bed B. Since it is impossible to separate from the device, the lifting knob 144 located close to the handle 133 on the front of the transfer device is operated as shown in Figure 7. At this time, the motor inside the lifting control box 140 rotates and the gear engaged with it rotates. By operating the part, the lifting shaft 143 is raised to a certain height.

When the lifting shaft 143 rises, the reinforcing bar 132 of the vertical lifting frame 130 connected thereto rises. As the reinforcing bar 132 rises, the vertical lifting frame 130 connected thereto and the two seat rotation frames connected thereto As (161) rises, the chairs (163) (163') of the two seat rotation frames (161) are spaced apart from the upper surface of the bed (B).

And, when the chairs 163 and 163' of the two seat rotation frames 161 are spaced apart from the upper surface of the bed (B), the transfer device is separated from the bed. At this time, the chairs 163 of the two seat rotation frames 161 are separated from the bed. ) (163'), the patient's load is concentrated on the rear part of the chair (163) (163'), causing the two seat rotation frames (161) to bend or rotate with the two seat rotation frames (161). Since stress may be concentrated in the two rotating pipe parts 131 of the combined vertical lifting frame 130 and damaged, the reinforcement 150 is connected to the magnet 166 of the seat bracket 165 installed on both sides of the two seat rotating frames 161. ) is separated and lowered.

The reinforcement bar 150 moving downward around the hinge axis 151 of the two seat rotation frames 161 comes into contact with the fixing bracket 113 of the bottom frame 100 as shown in Figure 8, and at this time, the reinforcement bar 150 Since the lower end of the fixing bracket 113 is coupled to the magnet 114, it is possible to prevent the reinforcement 150 from moving, and the reinforcement 150 is provided between the two seat rotation frames 161 and the bottom frame 100. ) is supported, so it is possible to prevent the seat rotation frame 161 from sagging due to the patient's weight.

On the other hand, when the patient is in critical condition and cannot go to the bathroom, the toilet 200 is installed by sliding both hooks on the guide parts 163a and 163b installed at the lower part of the seat rotation frame 161. By matching the toilet grooves 164 and 1641 of the two chairs 163 and 1631, it is possible to easily relieve urine and feces.
