And 11 are rollable on the guide rails 8 and 9, respectively.

In order to make the movement of the above-mentioned columns 5 and 6 in the width direction of the bed body 3 smoother, as shown in FIG. Second guide rails 12 and 13 are provided. On the other hand, the columns 5 and 6 are provided with the second guide rollers 14 and 15 which are rollable along the guide rails 12 and 13 while being received by the guide rails 12 and 13, respectively.

Further, in the movement of the bed body 3 in the width direction, in order to achieve synchronization between the two columns 5 and 6,
The bed body 3 is provided with racks 16 and 17,
On the other hand, the columns 5 and 6 are provided with pinions 18 and 19 which mesh with the racks 16 and 17, respectively.
The pinions 18 and 19 are adapted to rotate integrally with the connecting rod 20. Therefore, for example, one of the columns 5
When the rack is moved in the width direction of the bed body 3, the rack 16
The pinion 18 that meshes with rotates according to this movement.
The rotation of the pinion 18 is transmitted to the other pinion 19 via the connecting rod 20. When the pinion 19 rotates in this way, it moves along the rack 17, and this movement is transmitted to the other column 6. In this way, the movement of the columns 5 and 6 is synchronized.

A support member 21 is passed between the pair of columns 5 and 6. The support member 21 is indicated by an arrow 2 in FIG.
It can be moved along the stanchions 5 and 6, as shown at 2, and can also be stopped in the moved position. In order to drive and control such movement of the support member 21, the following configuration is adopted.

As best shown in FIG. 2, inside each of the struts 5 and 6 are lead screws 23 and 2 respectively.
4 are rotatably arranged about their respective central axes. A worm wheel 25 is fixed to one of the lead screws 23, and a handle 27 is attached to the column 5 so as to rotate integrally with a worm 26 that meshes with the worm wheel 25. Further, the rotation of the lead screw 23 is performed by rotating the connecting shaft 3 via the bevel gears 28 and 29.
The rotation of the connecting shaft 30 is transmitted to the lead screw 24 via the bevel gears 31 and 32. Therefore, when the handle 27 is rotated, the rotation is transmitted to the one lead screw 23 via the worm 26 and the worm wheel 25, and similarly, via the bevel gears 28 and 29, the connecting shaft 30, and the bevel gears 31 and 32.

It also serves as a reinforcement for 6.

The method of using the mobile bed apparatus 1 will be described below. First, a case where a sick person or the like is laid on the bed surface 2 of the bed apparatus 1 and the sick person or the like is transferred to another bed will be described. In this case, by operating the handle 27, the side bars 42 and 43 are moved in the direction indicated by the arrow 22, and are positioned on both sides of the body of the sick person or the like. Next, a plurality of hanger shovels 45 as an example of a hanger member are prepared. Each hanger shovel 4
Reference numeral 5 is made of a relatively rigid plate material, and has an L-shaped curved shape as a whole. At one end of the hanger shovel 45, a hook portion 46 that can be engaged with the side bar 42 or 43 is formed. These hanger shovels 45 are inserted under the body of the sick person or the like without lifting the sick person, and then the hook portion 46 is attached to the side bar 4.
2 or 43 is engaged. Then, the handle 27 is operated again, and the side bars 42 and 43 are displaced upward.
As a result, the body of the sick person or the like is floated from the bed surface 2. In this state, the columns 5 and 6 are moved in the direction indicated by the arrow 7, thereby bringing the sick person or the like to a position outside the space above the bed surface 2. At this time,
Another bed is located below the body of a sick person or the like.
Therefore, when the handle 27 is operated to displace the side bars 42 and 43 downward, the sick person or the like can be placed on the other bed. Next, the hanger shovel 45 is removed from the side bar 42 or 43, the side bars 42 and 43 are again displaced upward, and the columns 5 and 6 are returned to the state shown in FIG. At this time, if the bed apparatus 1 is in the way, it may be moved to any place.

In order to transfer the patient, etc., who has been transferred to another bed as described above, to the mobile bed apparatus 1 again, the above-described operation may be reversed. A sick person or the like who has been transferred to the mobile bed apparatus 1 is moved to the original bed or a place with other equipment according to the movement of the bed apparatus 1. At this time, if the arms 39 and 40 are rotated upward in accordance with the rotation indicated by the arrow 41, the side bars 42 and 43 are positioned directly above the sick person lying on the bed surface 2. Since it can be in a nonexistent state, it is possible to prevent the side bars 42 and 43 from giving a sick person a feeling of pressure.
