The third swing shaft 113c of the left main lifting unit 110A is also assembled in such a manner that it can slide on the second guide 115b of the main frame 120. The right side The third swing shaft 113c 'of the means 110B is connected to the main frame 120 so as to be rotatable. The third swing shaft 113c' of the means 110B is structured so that the main frame 20 can be stably and accurately operated according to the rising and falling.

2C, the lower end of the sub linker 113C is connected to the base 10 through a fourth swing shaft 113d.

In the main elevating units 110A and 110B having such a configuration, the motor 111A is operated according to the control signals of the wired or wirelessly connected controller to move the main frame 120 upward and downward.

More specifically, as can be seen in Figures 2b and 2c and Figure 2a, the two motors 111A of both main lifting means (110A) (110B) at the same time moving the plunger (111C) as the motor 111a ) Pivots around the support shaft 111B,

When the plunger pushes the bracket type pressing portion 113A 'protruding to the center of the relay linker 113A, the relay linker rotates by the lever principle, and thereby the lower second swing shaft 113b of the main linker 113B is rotated.

The sidebar 45W of the left wing frame 45B is lifted by the left riser 61B of the seesaw 61 of the safety elevating means 60 so as to rise slightly relative to the first longitudinal axis S1. The patient's right body part is stably supported.

It is also preferable that the free-floating bed B according to the present invention and the displacement means therefor, particularly the longitudinal displacement means 40 for the longitudinal folding mode, are provided with separate locking means for the purpose of improving safety and durability .

Especially, in the locking means, the respective support units pivot about the subordinate pivotal axis Sv by the above-mentioned longitudinal direction displacing means to unlock the support powder that ascends and descends, and the stationary support powder is locked.

That is, in the upper dashed line circle of FIGS. 6 and 6A, the locking means 50 is composed of the lockers 51, 51A, the lengths 53A, 53B, and the interlocking member 55.

If the seesaw bar 61 of the safety raising means 60 moves for the simplification and operation reliability of the power transmitting structure element,

(61) provided on both sides of the ascending / descending member (43) of the vertical displacement means (40) in accordance with the positions and the number of the pressing members (63) 61C)

The second link 53B provided at a lower portion of the seesaw shaft is pulled out of the main frame 20 and the first link 53A connected to the second link is moved so that the connection piece 51a The connecting rod locker 51A is moved,

The hook portion moves away from both ends of the vertical turning axis Sv by moving to the other non-coupling type locker 51 according to the turning of the interlocking member 55 connecting the two lockers 51 (51A)

In FIGS. 6B and 5, the support powder on the second and third columns V2 and V3 is released because the rising second vertical axis Sv2 of the two longitudinal pivots Sv is unlocked. .

In the drawing, only one of the first and second links 53A and 53B is provided for each of the longitudinal displacement means 40 at a position offset to one side.

In addition, as shown in FIG. 7, a total of four hooks 45h are provided at both ends of the common lifting body 45, in particular, the center frame 45a, and a catcher pin at a corresponding position of the main frame 20. 23 is provided

The safety function becomes more perfect,

Accordingly, when the locking means 50 is mounted on the support panel powder on one of the columns in which the load of the patient is not heard in the longitudinal folding mode, the longitudinal pivot axis Sv is lifted and the patient leaves the bed B , It is possible to prevent the problem of falling down.

On the other hand, when the support panel powder on the elevated column V2 (V3) is lowered, the motor 41A of the motor assembly 41 of the longitudinal displacement means 40 rotates in reverse and the cylinder 41B also moves in the opposite direction, The respective components 43A, 43A and 43B of the elevating member 943 move in the opposite direction,

The right wing frame 45B and the right side of the center pillar 45A are lowered,

Since the rising portion 61B is lowered by pressurizing and jogging as the pressing member 63 pressing the lowering portion 61A of the seesaw bar 61 of the safety raising means 60 is lowered, The wing frame 45B and the powder of the support panel P on the first column V1 also descend.

In accordance with the rotation of the seesaw shaft 61C in the opposite direction, the first and second links 53A,

The connecting piece 51a of the connecting-type locker 51A is hooked on the shaft 51s as the center, and then the end of the slave turning shaft Sv is hooked on the connecting piece 51a of the connecting-

At both side ends of the center frame 45a, two of the right and left two of the two pairs of hooks 45h are hooked again to the catcher pin 23 arranged at the corresponding position of the main frame 20.

Furthermore, the free-lying bed (B) according to the invention and the displacement means therefor, in particular the longitudinal displacement means (40) for the longitudinal folding mode,

Each of the support units is pivoted about the horizontal axis by the transverse displacement means,

When each of the support units pivots about the longitudinal pivot shaft by the longitudinal displacement means

It is possible to prevent collision of the respective support unit constituent support powder.

Such a shifting means can be solved by introducing the driving means so as to separately move each powder of the respective support panels P

In order to simplify the structure, the present invention implements the method in the common elevator 45.

That is, in Figure 7, in the wing frame (45B) connected to both sides of the center frame (45S) by the first and second longitudinal axes (S1) (S2)

A side bar 45W connected to the first and second longitudinal shafts S1 and S2 and the link bar 45w is formed so that the recess bar 45r functions as a displacement means .

That is, in a state in which the longitudinal folding mode is not performed, each powder of the support panel P is flat in the assembled bed B, and the outline of the panel powder on the first and second columns V1 and V2 And is supported by the outer frame portion of the main frame 20.

However, when one of the wing frames 45B rises for the longitudinal folding mode, the outline of the panel powder on the first and third columns V1 and V3 is deviated from the main frame 20,

At this time, the support panel powder of the outer periphery (first or third longitudinal row) of the buttress support unit P2 is located on the recess bar 45r constituting the disengagement means and is not on the same plane because it is displaced from other powders .

In addition, the support panel powder of the outer side (third or first column) of the other side of the butt support unit P2, which is not lifted by the longitudinal displacement means 40 by the safety elevating means 60, also forms a staggering means. It is located in the recess bar 45r, which is displaced from other powders.

In this state, even if the lateral displacement means 30 moves and the thigh support unit P1 (P3) moves and the transverse folding mode proceeds

There is no problem of collision with the outer support panel powder of the buttress support unit P2 located in the recess bar 45r of the both wing frame 45B and the smooth longitudinal folding mode and the horizontal folding mode can proceed.
