As shown in FIG. 6, the support columns 9 are lowered all at once and their legs 11 are in contact with the floor 3, and the base 2 is slightly lifted up so that all the wheels 4.5 are moved as shown in FIG. Move away from floor 3 to one side. As a result, the transport cart 1 is stably placed on the floor surface 3. Subsequently, by moving the operating member 51 upward in the opposite manner to the above, and retracting the piston 52 forward by hydraulic pressure,
At the same time, the pair of left and right support levers 31 on the front side are tilted and rotated by the same amount via the connecting rod 33, and thereby , the mounting table 35 is lowered to a horizontal state, and the lower surface of the mounting table 35 is brought into contact with the second surface of the bed. Next, by moving the auxiliary stand 43 located on the bed side backward against the action of the compression spring 49, the fitting grooves 47A of the front and rear fitting pieces 47 are separated rearward from the stopper bin 40. to release the engagement holding effect,
Then, the auxiliary table 43 is rotated toward the bed and placed horizontally on two sides of the bed, and in this state, the patient lying on the mounting table 35 is smoothly placed on the bed via the auxiliary table 43. It can be moved easily and extremely safely. After transferring the patient, by standing up and rotating the auxiliary table 43 in the opposite direction, the fitting grooves 4 of the fitting pieces 47 in front and rear
When 7A corresponds to the stopper pin 40, they are automatically fitted together by the action of the compression spring 49, and the auxiliary stand 43 can be held in the upright position. In addition, in order to move the transport vehicle l away from the bed, the lowering operating member 21 is moved from the lower position shown in FIG. 1 by stepping on the lowering operating member 24 from FIG. The connection rod 19 and the connection rod 2 are raised to one position.
0 is integrally moved rearward, and as a result, each rotating piece 17 of the four auxiliary supports 6 and the connecting part of the stopper member 14 move rearward through the dead center all at once, and by the action of the coil spring 13. Each support column 9 is raised simultaneously and each of its legs]
1 from the floor 3, so that each wheel 4.5 is grounded on the floor 3 as shown in FIG. Thereby, the transport cart 1 can be moved freely.

【Effect of the invention】. As described in detail below, the present invention is particularly characterized in that, on the underside of the mounting table, multiple locations in the front and back of the base body are rotatable around a common axis in a horizontal direction. A plurality of support levers are provided, each of which is supported by a plurality of support levers.
When one end of the three sides is pivotally attached to the lower side of the mounting table,
An operating body for reciprocating the other lower end of each of the support levers in the direction of the swinging force of the other end is connected, and the connecting rod is moved forward and backward by the operating body. The support levers are rotated simultaneously in the same direction by the same number of teeth to move the mounting table up and down in a substantially horizontal state. Therefore, when transferring a human body from the mounting table to the bed or vice versa, if the height of the bed is different from the mounting table, the height of the mounting table can be adjusted to the optimal position relative to the bed by operating the operating body. This allows the transfer of human bodies to be carried out extremely easily and quickly, and also extremely safely, by a small number of people. Further, the height of the mounting table can be adjusted simply by operating the one operating body. Furthermore, since each of the support levers is commonly connected to one continuous rod, and the continuous strokes are operated by one operating body, the structure of the mechanism for adjusting the height of the mounting table is simplified and it is possible to reduce the cost. It has excellent effects such as being able to be manufactured easily.
