DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described with reference to the drawings. The first embodiment shown in FIG. 1 to FIG. 3 is a table 1 for supine a patient, and an erecting mechanism 2 for elevating a patient's head side end which is one end of the table 1 to bring the table 1 into an upright and stowed state. And a footrest plate 3 attached to the end of the table 1 on the side of the patient's foot so as to protrude from the upper surface of the table 1. The table 1 has an upper body mounting portion 5 and left and right lower limb mounting portions 6 and 7 attached to a table frame 4. The upper body mounting portion 5 has a chest stopper belt 8 for attaching a patient to the upper body mounting portion 5. A lower limb stopper belt 9 is attached to the left and right lower limb placing portions 6 and 7. Two roller mounting arms 10 are mounted on the table frame 4 in a direction opposite to the foot rest plate 3 mounted on the table frame 4, and a rotatable roller is provided between the two roller mounting arms 10. 11 are attached, and casters 13 are attached to left and right ends of a roller shaft 12 of the roller 11, respectively.

The upright mechanism 2 has a rail 14 mounted vertically, a screw shaft 15 supported in the rail 14, and a screw shaft 15 screwed to the patient's head side of the table frame 4. And a drive unit 17 for rotating the screw shaft 15. The rail 14 is attached to and supported by the drive unit 17. The elevating body 16 includes a female screw portion 18 and an arm portion 19 extending in the horizontal direction.
Is determined in accordance with the length of the roller mounting arm 10 so that the table 1 reaches the vertical position when the table 1 stands up. An L-shaped fixed frame 20 placed on the floor and mounted on the floor is attached to the outer periphery of the erecting mechanism 2, and the fixed frame 20 is bent leftward or rightward at the bent portion of the fixed frame 20 in the side view. In order to prevent overturning, an appropriate length of the straight frame 21 is extended.

The driving section 17 is a caster 1 of the table 1.
It is housed in an appropriately high housing 23 having an upper surface inclined in three directions,
The drive unit 17 includes a geared motor 24 that is conductively connected to the screw shaft 15, an electric circuit unit 25 that controls the rotation of the motor 24, and an operation panel 26 that provides an instruction signal to the circuit unit 25. Housing 23 for improved operator convenience
And a foot switch 27 separated from the housing 23 is placed near the housing 23 and is provided side by side. An inclined plate 28 is axially attached at the same inclination angle as the upper surface 22 at the end of the inclined upper surface 22 of the housing 23 in the direction toward the patient's foot.
When the table 1 moves upright in the vertical direction or lays down in the horizontal direction, the rollers 11
It is used for rotating and running on the upper side and the housing upper surface 23.

When using the apparatus of the first embodiment, when the upright switch 35 of the operation panel 26 is pressed, the screw shaft 15 is rotated, the elevating body 16 moves up, and the end of the table 1 on the patient head side is moved. The table 1 moves upward and the table 1 is changed to the vertical position. During this vertical movement, the casters 13 at the patient's foot end of the table 1 roll on the floor, and the rollers 11
And rises to the housing upper surface 22. Next, operation panel 2
When the lying switch 30 of 6 is pressed, the screw shaft 15 rotates in the reverse direction,
As the elevating body 16 moves down, the patient's head side end of the table 1 moves down, and the table 1 is changed to the horizontal position. During this horizontal movement, the roller 11 descends from the inclined plate 28 and the upper surface 22 of the housing, and the casters 13 on the patient's foot end of the table 1 roll on the floor. Since the housing upper surface 22 and the inclined plate 28 which are inclined downward in the same direction as the direction of the patient's feet of the table 1 in the horizontal state are provided at the lower portion of the rail 14, the table 1 in the vertical state is moved to the horizontal state. At this time, when the elevating body 16 is lowered, the operation in which the roller 11 rolls on the upper surface 22 and the inclined plate 28 and the table 1 moves to the horizontal state can be started immediately.

The second embodiment shown in FIG. 4 is similar to the first embodiment shown in FIG.
A point that a female screw 36 slidably gripped by the elevating body 16 is externally fitted to the screw shaft 15 in the embodiment;
This embodiment is different from the first embodiment in that the driving unit 17 is mounted on the elevating body 16 in the embodiment. That is, the erecting mechanism 2 of the second embodiment includes a screw shaft 15 that is mounted vertically, a female screw 36 that is externally screwed onto the screw shaft 15, and the female screw 36 that is rotatably gripped. Elevating body 1 to which one end of table 1 is hung
6 and a drive unit 17 which is rotatably connected to a female screw 36 and mounted on the elevating body 16. The turning power of the keyed motor 24 of the drive unit 17 is controlled by the worm 3 attached to the female screw 36.
7 and worm wheel 38 externally fitted to female screw 36
Is conducted by the conducting member consisting of In the second embodiment, the table 1 is moved up and down by rotating the female screw 36 without rotating the screw shaft 15.

In the third embodiment shown in FIG. 5, the upright mechanism 2 for raising the end of the table 1 on the side of the patient's head is replaced by a wire 29 instead of the screw shaft 15 and the lift 16 in the first embodiment.
And a mechanism using the winding drum 33. That is, the erecting mechanism 2 of the third embodiment is slidably held by the rails 14 and hooks the end of the table 1 on the side of the patient's head.
And a wire 29 that hangs down from the upper part of the rail 14 and locks the end of the table 1 on the patient's head side, and a power unit 31 that is placed on the floor and winds the wire 29. The lower part of the rail 14 is fixed to the housing 23 that houses the power unit 31, and pulleys 32 are provided on the left and right sides of the upper end of the rail 14, and the wire 29 drawn out from the winding drum 33 of the power unit 31 is hung. Has been turned. The wire 2
9 is hooked on the table 1 at the end of the patient's head.

An inclined body 34 inclined downward in the same direction as the side of the patient's foot on the table 1 in the horizontal state is a rail 14.
The inclined body 34 is provided to immediately start the movement of the table 1 to the horizontal state when the wire is drawn out when the table 1 in the vertical state is moved to the horizontal state. is there. That is, when moving the table 1 in the vertical state, the wire 29 is pulled, the patient's head side end of the table 1 is pulled up, and the casters 13 are riding on the inclined body 34. When moving 1 horizontally, wire 29
And lower the end of the table 1 on the patient's head side. Then, the caster 13 on the patient's foot side of the table 1 descends from the slope of the inclined body 34, and when the caster 13 arrives on the horizontal floor, the caster 1 is moved from the center of gravity of the table 1.
3 moves toward the patient's foot, and the table 1
Continues to move horizontally.

The power unit 31 includes a winding drum 33 for fixing the base end of the wire 29 and winding the wire 29.
A geared motor (not shown) for rotating the take-up drum 33, an electric circuit (not shown) for controlling the rotation of the geared motor (not shown), and instructions to the electric circuit (not shown). It comprises an operation panel 26 for giving a signal.
Operate the operation panel 26 and use the winding drum 33 to wire 2
9, the table 1 is erected when the tip of the wire 29 is pulled up, and the wire 29 is paid out.
When the tip of the table 1 is lowered, the table 1 descends by its own weight and lies down.

In the fourth embodiment shown in FIG. 6, a winding drum 33 is mounted on the back surface of the table 1 opposite to the rail 14, and the tip of a wire 29 fed from the winding drum 33 is fixed to the rail 14. One end of the rail 14
And one end of the table 1 is gradually raised with the action of winding up the wire 29,
The table 1 is moved to a vertical state.
