The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a specific example of the floor plate support frame tilting mechanism of the device according to the present invention. 1 is a floor plate support frame. Both side frames 1a, 1 of this floor plate support frame 1
A pair of lower support bases 2 and 2' are fixed vertically downward at positions x and y opposite to a', and a rotating rod is further provided between the tips 2b and 2b' of these lower support bases 2 and 2'. 3 is hung horizontally so that it can rotate freely. A pair of rotating arms 6, 6' are fixed perpendicularly to the rotating rod 3 from both ends of the rotating rod 3, and the tips (free ends) of these arms 6, 6' support the supports 9, 8' of the legs 8, 8'. 9', and are rotatably connected to each other. In addition, an operating arm 7 is provided in the middle part of the rotating rod 3.
is fixed perpendicularly to the rotating rod 3. The lower support bases 2, 2' are located inside the support bases 9, 9' of the legs 8, 8', and the lower support bases 2, 2' and the legs 8,
The links 4, 4' are attached to the supporting bases 9, 9' of the pivot arm 6, 8'.
6' and rotatably connected thereto.

Reference numeral 5 denotes a telescopic rod, which has a cylinder body 21 as shown in FIG. A piston body 25 is installed in the oil chamber 24, and the piston body 25 partitions the oil chamber 24 into 24A and 24B.

Further, a piston rod 26 is connected to one side of the piston body 25. One end of this is connected to one side of the piston body 25, and the other end extends to the outside of the cylinder body 21 through the oil chamber 24A and is connected to the horizontal beam 12 of the floor plate support frame 1. This connection is the first
As shown in the figure and FIG.
This is done by rotatably fixing the fixing piece 36 with a pin 37 to a fixing piece 36 having a U-shaped cross section fixed on the lower side at a position substantially opposite to . Also,
A passage 27 communicating the oil chambers 24A and 24B is formed in the piston body 25, and a valve 28 for opening and closing the passage 27 is installed on the passage 27. Furthermore, inside this piston rod 26 there is a push rod 29.
is inserted through it in the longitudinal direction. One end of this is connected to the valve 28, and the other end is connected to the piston rod 2.
The valve 28 opens and closes the passage 27 by pushing or pulling back the protruding portion of the push rod 29.
That is, the push rod 29 closes the valve 28 in the extended position to lock the telescopic rod 5, and when the push rod 29 is pushed in, the valve 28 opens and the oil chambers 24A and 24B are connected through the passage 27. This allows the piston body 25 to move.

The pushing mechanism of the push rod 29 will be described in detail with reference to FIGS. 1 and 5 as follows. FIG. 5 is an enlarged view of the telescopic rod operation section 11 shown in FIG. 1. Support pieces 32, 33 are fixed to the side frames 1a, 1a' of the floor plate support frame 1.
has a pair of operating lever handles 10, 1 at the tip.
An operating rod 34 equipped with 0' is rotatably mounted horizontally,
As a result, the operating lever handles 10, 10' are interlocked with each other via the operating rod 34. Furthermore, a connecting piece 3 is attached to an arbitrary part of the operating rod 34.
5 is fixed to the fixed piece 38, and the trigger lever 30 is rotatably fixed to the fixed piece 38 by a pin 40 so as to be in contact with the tip of the push rod 29.
The connecting piece 35 and the tip of the trigger lever 30 are connected via an operating wire 31. During this connection, one end of the wire 31 is connected to the connecting piece 35, and the other end is connected to the tip of the trigger lever 30 through the guide piece 39.

The above-mentioned telescopic rod 5 is located at the end 5a of the cylinder body 21.
is rotatably connected to the free end 7a of the operating arm 7,
The tip of the piston rod 26 is fixed to the horizontal beam 12 of the floor plate support frame 1 via the fixing piece 38 as described above, thereby forming a floor plate support frame tilting mechanism.

The device of the present invention is such that the floor plate support frame tilting mechanism A constructed in this manner is independently provided on both the head side A and the foot side B of the floor plate support frame 1, as shown in FIGS. 2 and 3. It is. In this case, the links 4, 4 and 4', 4' on the head side A and the foot side B are respectively connected to the lower support base 2,
2' and are connected so as to face each other.
In addition, Fig. 3 shows how to lift the bed by operating the floor plate support frame tilting mechanism A on the head side of the bed as described later.
Shows the tilted state.

Since the present invention is constructed in this way, for example, when trying to lift the head side A of the bed as shown in Figure 3, when the operating lever handles 10 and 10' in Figure 1 are turned in the direction of the arrow, The operating rod 34 rotates in the direction of the arrow, and at the same time the connecting piece 35 also rotates in the direction of the arrow, and the operating wire 31 is pulled in the direction of the arrow. At this time, as shown in FIG. 5, the trigger lever 30 rotates in the direction of arrow D, and the head (tip protrusion) of the push rod 29 of the telescoping rod 5 is rotated.
is pushed in to open the valve 28, which allows the gas pressure in the high pressure gas chamber 23 to move the piston body 25 through the oil in the oil chamber 24, and the piston rod 2
Push 6 outward. At this time, since the tip of the piston rod 26 is fixed to the horizontal bar 12 of the floor plate support frame 1 via the fixing piece 38, the reaction force causes the cylinder body 21 to move in the opposite direction to the direction of the force of the piston rod 26, that is, The actuating arm 7 is pushed in the direction of the actuating arm 7, causing the actuating arm 7 to rotate, and at the same time rotating the rotating rod 3 in the direction of the arrow, as shown in FIG. As a result, the floor plate support frame 2 is tilted from the parallel state shown in FIG. 2 as shown in FIG. 3, and the head side A of the bed is lifted. Next, the operating lever handle 1
Returning 0,10' to the original position, push rod 2
9 is released, the valve closes the passage 27, and the communication between the oil chambers 24A and 24B is blocked. Therefore, the movement of the piston body 25 is stopped and fixed at that position, and at the same time, the position of the piston rod 26 is changed. is also fixed in that position, and the bed remains raised.

Since this lifting is achieved by the presence of the links 4, 4' and the pivot arms 6, 6', high structural strength can be maintained. Moreover, this lifting is very easily achieved by actuation of the telescopic rod.

When lowering the bed, turn the operating lever handles 10, 10' in the direction of the arrow in FIG. When force is applied, the gravity of the patient's weight on the bed is added, and it can be easily lowered to its original state with a small load.

Moreover, the floor plate support frame tilting mechanism (a) is installed independently on both the head side and the foot side of the bed, eliminating the need for the underframe 107 as shown in the conventional example shown in FIG. is the leg support 9,
Links 4, 4' located on the inside of 9', that is, on the head side and foot side, are connected so as to face each other from the leg support bases 9, 9' to the lower support bases 2, 2', respectively. Therefore, the space at the bottom of the bed, especially the lower part of the space, becomes wider, ensuring sufficient space at the bottom of the bed to store accessories such as the bed and locker (Figures 2 and 3 show locker X). This device is extremely useful in practice.
