DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed apparatus which is effective for preventing bedridden of bedridden users such as sick and elderly people.

[0002]

2. Description of the Related Art A patient who cannot roll over or wake himself must remain in a supine position for a long period of time. As described above, if the patient remains in the supine position for a long period of time, a so-called bed sore occurs, and the patient's pain increases. Therefore, it is necessary to appropriately change the patient's body position to prevent the bed sore. However, such a bed apparatus has been developed.

Conventionally, the following configuration has been adopted as this kind of bed apparatus. That is, the bed apparatus has a bed body, and a rotating frame is provided on the bed body so as to be rotatable in the left-right direction about the center in the width direction as a rotation axis. The rotating frame is provided with a floor plate. The floorboard is composed of a central floorboard and side floorboards connected to both sides of the central floorboard so as to be rotatable only upward.

When the rotating frame is rotated left and right around the center in the width direction as a rotation axis, the rotating floor descends, and the side floor plate at one end in the width direction hits a stopper and moves downward. When the rotation is prevented, the bending is performed in the upward direction. Thereby, the patient who is lying on the central floor plate changes his or her body position in accordance with the rotation of the central floor plate, and is prevented from falling from the floor plate body by the side floor plate bent upward. Therefore, bedsores can be prevented by changing the body position by rotating the rotating frame alternately in the left-right direction.

In the bed apparatus having the above-mentioned structure, when changing the position of the patient, the rotating frame is swung in the left-right direction with the center in the width direction as a fulcrum, so that the central floor plate of the floor plate is moved as described above. The rotation frame is interlocked with the rotation of the rotation frame.

[0006] Therefore, the rotating frame is rotated in such a manner that one of the right and left is raised and the other is lowered with the center in the width direction as a fulcrum, and the center floor plate is interlocked with the rotating motion. ing.

As described above, when the rotating frame is rotated around its center in the width direction, a sufficient space is secured on the lower surface side of the rotating frame so that one end in the width direction can rotate downward. Must. For that purpose, the height of the bed body, that is, the supporting height of the central floor plate with respect to the bed body must be increased.

When the supporting height of the central floor plate is increased, it is difficult for a user to get on and off the upper surface of the center floor plate. In particular, when the user is a sick person, it may not be possible to get on and off by himself, which is very inconvenient. . Therefore, the lower the supporting height of the floor plate body provided on the bed body, the easier it is to use the patient when getting on and off.

Further, if the floor plate is rotated in order to change the position of the patient while the support height of the central floor plate is high, the patient may feel uneasy. In this case, the support height should be as low as possible. Good.

[0010] In addition, when a supine patient undergoes medical examination and care, if the supine patient is too low in support height, it may be difficult to perform the examination and care. It is desirable to be able to change the height.

On the other hand, the floor plate comprises a central floor plate and a pair of side floor plates connected to both sides in the width direction so as to be rotatable only upward. Conventionally, the center floor plate and the side floor plate are formed separately, and the side floor plate is connected to the center floor plate by a hinge or the like so as to be rotatable only upward. Therefore, after separately manufacturing the side floor plate and the center floor plate, they must be connected,
In many cases, it takes a lot of trouble to manufacture and assemble.

[0012]

As described above, in the conventional bed apparatus, when changing the position of the patient, one end in the width direction of the central floor plate forming the floor plate is raised and the other end is lowered. Because of the pivotal structure, it is necessary to secure a space on the lower surface side of the central floor plate so that the other end in the width direction of the central floor plate can be lowered. For this reason, the supporting height of the floor plate body is increased, and the patient cannot get on and off by himself, which makes it difficult to use.

An object of the present invention is to provide a rotary frame for changing the position of a patient even when the supporting height of the floor plate is sufficiently low so that the patient can easily get on and off the vehicle. It is an object of the present invention to provide a bed device which can swing in the left-right direction, and which can support the patient at a height which facilitates the work when consulting or nursing.

Another object of the present invention is to provide a bed apparatus capable of efficiently manufacturing a floor plate composed of a center floor plate and side floor plates, and not requiring extra labor when assembling. Is to provide.

[0019]

An embodiment of the present invention will be described below with reference to the drawings. The bed apparatus shown in FIG. The base 1 is formed in a rectangular frame shape, and casters 2 with stoppers are provided at four corners on the lower surface. As shown in FIG. 3, a pair of brackets 3 are provided at both ends in the longitudinal direction on both sides of the base 1 at corresponding positions in the width direction. A pair of rotating shafts 5 constituting an up-down link mechanism 4 are rotatably mounted on each pair of brackets 3. One end of a pair of levers 6 is fixed to both ends of each rotating shaft 5. Both ends of the support shaft 7 are fixed to the other end of each pair of levers 6. Rollers 8 are provided at both ends of the pair of support shafts 7, respectively.
Are provided rotatably.

One end of a first arm 9 is fixed to a middle part of one rotating shaft 5, and a second arm is fixed to a middle part of the other rotating shaft 5.
The middle part of the arm 11 is fixed. One end and the other end of an interlocking rod 12 are pivotally connected to the other end of the first arm 9 and one end of the second arm 11 projecting downward. A vertical drive mechanism 13 is provided on the upper surface of the intermediate portion of the
Is provided. The vertical drive mechanism 13 includes a drive source 14 swingably attached to the interlocking rod 12 and a drive shaft 15 driven forward and backward by the drive source 14.
The tip of the drive shaft 15 is pivotally connected to the other end of the second arm 11.

When the vertical drive mechanism 13 is actuated to drive the drive shaft 15 in the projecting direction, the second arm 11 rotates counterclockwise as shown by the arrow a in FIG. One rotation shaft 5 is linked with the movement. When the second arm 11 rotates, the rotation causes the interlocking rod 12 to slide in the direction indicated by the arrow b, and the first arm 9 rotates counterclockwise as indicated by the arrow c. .

If the first arm 9 and the second arm 11 rotate in the same counterclockwise direction, each pair of levers 6 having one end connected to each arm is shown in FIG. From the state shown in FIG.

Rollers 8 at both ends of the support shaft 7 connected to each lever 6 are provided with guide rails having a U-shaped cross section provided on both inner surfaces of a mounting frame 21 having a rectangular frame shape. Is rotatably engaged with the head 22. Therefore, the pair of levers 6
Is rotated in the upright direction, the frame 21 is raised via the roller 8 by the rotation. FIG. 10 shows a state in which the mounting frame 21 is raised on the base 1.

In order to prevent the lifted mounting frame 21 from freely moving along the longitudinal direction by the engagement between the guide rail 22 and the roller 8, the mounting frame described above is used. As shown in FIG. 3, one end and the other end of the connection link 23 are rotatably connected to the arm 21 and lever 6 as shown in FIG. The connecting link 23 prevents the placing frame 21 supported by the engagement of the roller 8 of the guide rail 22 from freely moving in the sucking direction. Also, by removing the connecting link 23, the above-mentioned mounting frame 21 is used as a base.
1 can be disassembled.

On the other hand, as shown in FIG. 4, the pivot 6 of the lever 6 is A, the middle point in the longitudinal direction is B, the other end to which the roller 8 is attached is C, and one end is at the middle point B. Assuming that the other end of the connected link 23 is D, AB, BD, BD, BC
Are set to AB = BD and BD = BC. Therefore, the triangle formed by the three points A, B, and D and the triangle formed by the three points A, B, and D are both isosceles triangles.

The points A to D when the mounting frame 21 is raised as shown by a chain line in FIG.
', B', C ', D', A ', B', D '
The triangle formed by the points and the triangle formed by the three points A ', B', and D 'are also isosceles triangles.

Therefore, when the lever 6 is turned up from the lying state in the upright direction, the above-mentioned triangles maintain an isosceles triangle.
As shown by the arrow, it rises to point D 'in the vertical direction. Also, point C
And point D are displaced upward to points C 'and D' while maintaining substantially the same height in the horizontal direction.

Therefore, since the mounting frame 21 can be raised and lowered in a horizontal state without sliding in the horizontal direction, the mounting frame 21 may be inclined or the longitudinal end thereof may be inclined. There is no collision with the wall.

On the upper surface of the mounting frame 21, a supporting frame 25 having a rectangular frame shape larger than the mounting frame 21 is removably mounted and fixed. As shown in FIGS. 2 and 3, the supporting frame 25 has a vertical rod 28 attached to both ends of three horizontal rods 26 along the width direction via connecting members 27. On the upper surface of each vertical rod 28, a contact plate 28a made of synthetic resin is provided over the entire length in the longitudinal direction.

A pair of receiving members 29 are provided upright at both ends of the pair of horizontal bars 26 located at both ends in the longitudinal direction of the support frame 25. Each receiving member 29 is formed with an arc-shaped concave portion 29a which is open on the upper surface and the inner surface.

A rotary frame 32 is disposed between the pair of vertical rods 28 of the support frame 25. A pair of supporting rollers 33 are rotatably provided on both longitudinal end surfaces of the rotating frame 32, respectively. Each support roller 3
Reference numerals 3 are engaged and supported by recesses 29a formed in the receiving member 29, respectively.

At both ends of the pair of vertical bars 28 of the support frame 25, connecting brackets 30 are vertically provided with their upper ends fixed. The lower ends of the connecting brackets 30 are detachably attached to the four corners of the mounting frame 21 as shown in FIG. Accordingly, the support frame 25 is interlocked with the vertical movement of the placing frame 21 described above.

As shown in FIG. 2, between the two end portions of a pair of horizontal rods 26 located at one longitudinal end of the support frame 25 and a halfway portion.
As shown in FIGS. 3 and 6, a pair of mounting rods 34 are provided. Between the intermediate portions of the mounting rods 34, the horizontal
An auxiliary horizontal rod 26a is provided in parallel with the sixth rod 6. These rod members 26, 26a, 34 are provided with a swing driving means 35 for swinging the rotating frame 32 in the left-right direction.

The swing drive means 35 is configured as shown in FIGS. That is, as shown in FIG. 6, a bracket 36 is provided on the lower surface side of one of the mounting rods 34, and one end of a drive source 37 is pivotally attached to the bracket 36. The drive source 37 includes a motor 38a and the motor 38a.

And a movable body 38c that moves along the screw shaft 38b.

The movable body 38c has a pair of L-shaped first links 39 constituting a link mechanism 40A shown in FIG.
Is pivoted at one end. The other ends of the first links 39 are fixed to the support shaft 41. This support shaft 41 is shown in FIG.
As shown in FIG. 6, it is rotatably mounted on a bracket 40 erected on one of the horizontal rods 26 and the auxiliary horizontal rod 26a.

One end of the support shaft 41 protrudes from one bracket 40 toward the other horizontal rod 26, and one end of a second rod 42 having a straight rod shape is fixed to the protruding end. An interlocking pin 43 protrudes from the other end of the second link 42. The interlocking pin 43 is slidably engaged with a long hole 44a, 45a formed at a predetermined length from one end side in the longitudinal direction of the third link 44 and the fourth link 45 to a halfway portion and cannot be pulled out. I agree.

The third link 44 and the fourth link 45
One end of a connecting pin 46 is pivotally connected to the other end of the connecting pin 46 as shown in FIG. One end of each of the connection links 47a and 47b and one side surface of a holding member 49 fixed to both ends of the steady rest link 48 are pivotally connected to each connection pin 46, respectively. The other end of each of the connecting links 47a and 47b is pivotally connected to both ends in the width direction of one end in the longitudinal direction of the rotating frame 32, respectively.

It is to be noted that support rollers provided at the other ends of the connecting links 47a and 47b and both ends of the rotating frame 32 are provided.
The roller 33 is attached to the rotary frame 32 by a single pin 51 as shown in FIG. 7 (only 47b is shown).

On the other side surface of the holding member 49, a substantially L-shaped steady rest as an engaging portion, which is open to one end surface and the lower end surface located inside the width direction of the support frame 25, is provided. A groove 50 is formed. As shown in FIGS. 7 and 9, an engaging pin 52 as an engaging body protruding from the other horizontal rod 26 toward the auxiliary horizontal rod 26 a slides in the steady groove 50 of the pair of holding members 49. Freely engaged. As shown in FIG. 9, the distance L1 between the pair of engaging pins 52 is set slightly larger than the distance between the open ends of the pair of steady grooves 50 and smaller than the distance L2 between the ends of the steady grooves 50. Have been.

When the rotary frame 32 is in a horizontal state, the pair of engaging pins 52 are engaged with the steadying grooves 50 of each holding member 49. Thereby, the rotating frame 32
Are held without rattling in the left-right direction. That is, since the rotary frame 32 is swingably supported by the link mechanism 40, the link mechanism 4
When 0A is not driven, that is, when the rotary frame 32 is in a horizontal state, it is inevitable that the links play in the swinging direction due to the play of each link.

However, when the rotating frame 32 is in a horizontal state, the pair of engaging pins 52
9, the rotation frame 32 is prevented from swinging in the left-right direction.

In FIG. 8, the movable body 38c of the drive source 37
Is driven in the direction of the arrow A, the first link 39 rotates in the direction of the arrow B, and when the second link 42 interlocks with the rotation, the first link 39 is provided at the other end of the second link 42. The interlocking pin 43 engages with the upper end of the long hole 45a of the fourth link 45 to rotate the link 45 in the upright direction shown by the arrow D in FIG. Slide.

When the fourth link 45 starts to rotate,
By this rotation, the steady rest link 48 is also slid in the horizontal direction indicated by the arrow C. Thereby, the steadying groove 50 of one holding member 49 located on the upper end side of the fourth ring 45 is disengaged from the one engaging pin 52, and the other engaging pin 52 is prevented from swinging by the other holding member 49. It slides relatively to the terminal side of the groove 50.

As a result, the steady link 48 is rotatable about the other engaging pin 52 as a fulcrum, and is rotated in conjunction with the rotation of the fourth link 45. When the steady rest link 48 is rotated, the rotation frame 32 is rotated by this rotation as shown by the chain line in FIG.
Interlock through b. In other words, the other end of the rotating frame 32 rises above the supporting frame 25 with the supporting roller 33 at one end in the width direction supported by the concave portion 29a of the receiving member 29 as a fulcrum.

When the first link 39 is rotated in the direction opposite to the arrow B while the rotary frame 32 is inclined, and the movable body 38c of the drive source 37 is driven in the direction opposite to the arrow A,
The rotating frame 32 and the steady rest link 48 rotate in the falling direction. When the steady rest link 48 descends to a substantially horizontal state, the steady rest groove 5 of one of the holding members 49 is formed.
The one engagement pin 52 abuts on the lower surface 50a (shown in FIG. 9) of the open end 0. When the first link 39 is further driven from this state, the interlocking pin 43 slides up the long hole 44a of the third link 44 to abut on the end, and this third link 44 is indicated by an arrow E in FIG. Press in the direction shown. Accordingly, the steady link 48 slides in the horizontal direction opposite to the arrow C, so that the one engaging pin 52 is engaged with the steady groove 50 of the one holding member 49 again. In other words, the rotating frame 32 is held in a horizontal state where the rotating frame 32 hardly swings in the left-right direction.

From this state, the movable body 38c of the drive source 39
Is driven in a direction opposite to the previous direction, that is, in a direction opposite to the arrow A,
Since the third link 44 rises in the rising direction, the rotating frame 32 can be swung about the other end in the width direction as a fulcrum.

The supporting frame 25 and the rotating frame 32
A floor plate 61 is provided on the upper surface side. As shown in FIG. 10 (a), the floor plate 61
2 and a pair of side floor plates 64 connected to both sides of the center floor plate 62 by hinges 63 having a configuration described later so as to be rotatable only in the ascending direction. .

Each of the floor plates 62 and 64 is plural, in this embodiment, first to fourth, four floor portions 62a to 62d and 64a to 64d.
64d, and the floor portions of the respective floor plates 62 and 64 are sequentially connected to the four mounting frames 65a to 65 rotatably connected.
d. The floor portions 62a to 62d of the central floor plate 62 are fixed to the mounting frames 65a to 65d, respectively, and the floor portions 62a to 62 of the side floor plate 64.
d is placed on the mounting frames 65a to 65d,
Thereby, it can be turned upward.

Of the floors, only the second floor 62b of the central floor plate 62 is detachably fixed to the rotating frame 32, and the other floors are mounted on the rotating frame 32. It has just been placed.

As shown in FIG. 10B, each floor 62a
62d and 64a to 64d, the central floor plate 62 and the pair of side floor plates 64 are integrally formed by blow molding synthetic resin. The center floor plate 62 and the side floor plate 64 are formed into a hollow shape having a predetermined thickness, and the upper end in the thickness direction of the center floor plate 62 and the upper end in the thickness direction of the side floor plate 64 are connected to the hinge 6.
3 are integrally connected by a thin portion.

Therefore, the side floorboards 64 are connected to the central floorboard 62.
Can be rotated in the ascending direction shown by the chain line in the same figure, and the downward rotation is regulated by the contact between the opposing end faces 62a, 64a of the floor plates 62, 64. I have.

At the time of blow molding, a plurality of ventilation holes 66 are formed in each floor portion in the thickness direction thereof. Thus, the floor plate 61 has air permeability in the thickness direction.
Each of the floors 62a to 62d and 64a to 64d is made of two types of molded bodies having different lengths, and a pair of floors located at both ends in the longitudinal direction is formed by arranging two molded bodies in parallel. The two floors located therebetween are formed by one molded body having different lengths.

When the rotating frame 32 is rotated by the rocking drive means 35 and the central floor 62 of the floor plate 61 is interlocked with the rotation, one of the side floors 64 located in the ascending direction is moved. The state of being flush with the central floor plate 62 is maintained, and the other side floor plate 64 located at the lower end side abuts against the abutting plate 28a provided on the side of the support frame 25 to move downward. The rotation is prevented, so that the motor is bent upward at a predetermined angle.

Thus, the user lying on the floor plate 61 is turned (raised) by the central floor plate 62 rotating in the left-right direction, and is bent to the upper surface side of the central floor plate 62 at that time. The side floor plate 64 prevents the user from falling off the floor plate body 61.

The support frame 25 may be provided with a roller (not shown) instead of the contact plate 28, and the roller may be brought into contact with the side floor plate 64 to be bent. . As shown in FIG. 3, a floor portion 61a of each floor plate 62, 64 of the floor plate body 61,
An undulating drive mechanism 71 for raising and lowering the 64a is provided. The raising / lowering drive mechanism 71 includes a box 72 containing a power transmission mechanism (not shown), and a pair of drive sources 7 provided on one side and the other side of the box 72.
A first rotating shaft 74 which is provided at one end of the box 72 so as to protrude from both side surfaces thereof and is driven to rotate by the one driving source 73; A second rotation shaft 75 that is provided so as to protrude both ends from the surface and is rotationally driven by the other drive source 73. Both ends of each of the rotating shafts 74 and 75 are rotatably supported by brackets 76 provided on both sides of the rotating frame 32, respectively.

One end of a first lifting arm 77 is fixed to both ends of the first rotating shaft 74, and the second rotating shaft 75
One end of a second lifting arm 78 is fixed to both ends of the arm. Rollers 79 are rotatably provided at the other ends of the push-up arms 77 and 78, respectively.

The roller 79 provided on the first lifting arm 77 has a mounting frame 65a to which the first floor portion 62a of the central floor plate 62 shown in FIG. 10A is mounted.
The roller 79 provided on the second push-up arm 78 comes into contact with the mounting frame 65c of the third floor portion 62c of the central floor plate 62.

Each roller 79 is attached to each mounting frame 65a,
When the first rotating shaft 74 is driven to rotate in the state of being brought into contact with the first floor 65c and the first lifting arm 77 is rotated in the ascending direction, the first floor portion 62a of the central floor plate 62 rises in the upright direction. To the first floor portion 6 of the pair of side floor plates 64.
4a is also linked.

When the second rotating shaft 75 is driven to rotate and the second push-up arm 78 is rotated in the upward direction,
The third floor portion 62c of the central floor plate 62 is turned in the upright direction, and the fourth floor portion 62d is interlocked with the third floor portion 62c. Further, when the third and fourth floor portions 62c and 62d of the center floor plate 62 rotate, the third and fourth floor portions 64c and 64d of the pair of side floor plates 64 also move.

Next, the operation of the bed apparatus having the above configuration will be described. The floor plate 61 provided on the upper surface side of the support frame 25 moves up and down and rotates in the width direction (rolling).
And three operations of raising and lowering the floor.

In order to perform the vertical movement, the vertical drive mechanism 13 is operated to drive the drive shaft 15 in the projecting direction. As a result, the levers 6 provided at both ends thereof can be raised from the laid state via the pair of rotating shafts 5, so that the mounting frame 2 can be rotated in accordance with the rotation of the levers 6.
1 can be raised.

On the upper side of the mounting frame 21, a rotating frame 32 on which the floor plate 61 is mounted is supported by a supporting frame.
Since they are provided via the program 25, they rise in conjunction with each other. That is, when a patient lying on the floor plate 61 is to be cared for or consulted, the height of the floor plate 61 can be adjusted so that the patient can easily do this. When getting on and off the
By making the floor plate 61 sufficiently low, getting on and off becomes easy.

To rotate the floor plate 61 in the width direction, the drive source 37 of the swing drive means 35 is operated to drive the link mechanism 40A. In the link mechanism 40A, the third link 44 or the fourth link 45 is driven in the ascending direction according to the moving direction of the movable body 38c of the driving source 37.

When the fourth link 45 is driven in the ascending direction, as described above, the rotating frame 32 has a width around the roller 51 engaged with the concave portion 29a of the receiving member 29 at one end in the width direction. The other end in the direction rotates upward.

If the other end of the rotating frame 32 is raised with the one end in the width direction as a fulcrum, the floor plate 61 is interlocked with the rotation. That is, as shown by the chain line in FIG. 8, the floor plate 61 has its central floor 62 raised at one end in the width direction at the other end, whereby one side floor plate 64 connected to one end in the width direction is The lower surface is the contact plate 2 of the support frame 25.
The other side floor plate 64, which is bent upward in contact with 8 a and is connected to the other end side, cooperates with the center floor plate 62 in the same plane.

If the drive source 37 is operated so that the third link 44 is driven in the upward direction, the rotation frame 3
2 can be rotated in a direction opposite to the previous direction. Therefore, if the drive direction of the movable body 38c by the drive source 37 is changed, for example, at predetermined time intervals, the central floor plate 62 of the floor plate body 61 can be alternately rotated left and right by the rotating frame 32. .

If the center floor plate 62 is alternately rotated left and right at predetermined time intervals, the position of the user lying on the floor plate body 61 can be changed to left and right. Thereby, it is possible to prevent a sick or elderly person who needs to lie for a long period of time from incurring a floor collapse, and one end side in the width direction which is the base end side of the rotating central floor plate 62. Is bent upward, and the floor plate 61 is substantially L-shaped.
The character shape prevents the user whose posture has been changed leftward or rightward from falling from the floor plate 61.

As described above, when changing the position of the user lying on the floor plate 61, the center floor plate 62 is driven in a direction in which the other end rises with one end in the width direction as a fulcrum.
For this reason, the center floor plate 62 can be rotated without displacing the one end in the width direction, which is the lower end side of the rotating center floor plate 62, substantially below the support height of the floor plate body 61. Even if the supporting height of the user is sufficiently low, the user can change the posture of the user by rotating the central floor plate 62 in the left-right direction.

When the user changes the body position by rotating the central floor 62 in the left-right direction, if the support height of the floor plate 61 is high, the user may feel uneasy. It is better to do it in

If the supporting height of the floor plate 61 can be made sufficiently low, it is easy to get on and off the floor plate 61, so that the user can get on and off without a caregiver, especially when the user is sick or elderly. Sometimes it becomes.

When the floor plate 61 is in a horizontal state, a pair of engaging pins 52 provided on the support frame 25 are provided.
Engages with the steadying groove 50 of the holding member 49 provided on the rotating frame 32 side, and prevents the rotating frame 32 from swinging in the left-right direction.

Therefore, when the rotating frame 32 is used in a horizontal state, it is possible to prevent the floor plate 61 from rattling in the left-right direction and giving the user discomfort. In other words, even if the rotating frame 32 is swung by the link mechanism 40A, the rotating frame 32 can be prevented from rattling.

Further, the engagement pin 52 and the steadying groove 5
When the link mechanism 40A is engaged, the link mechanism 40A is automatically engaged and disengaged by activating the link mechanism 40A. Since no operation is required at all, it is easy to use and very convenient.

In order to raise the floor plate 61, the floor plate 61 is leveled and the up / down drive mechanism 71 is operated. That is, the pair of driving sources 73 is operated to rotate the first rotating shaft 74 and the second rotating shaft 75, and the lifting arms 77 and 78 are linked with the first rotating shaft 74 and the second rotating shaft 75.

When the first lifting arm 77 is driven in the upward direction, as shown by the chain line in FIG.
Is raised, and the first floor portions 64a of the pair of side floor plates 64 are also interlocked with it, so that the user can raise the upper body. When the second push-up arm 78 is driven in the ascending direction, the third floor portion 62c of the central floor plate 62 moves in a direction in which the other end side rises with one end connected to the second floor portion 62b as a fulcrum. , The one end of the fourth floor portion 62d connected to the other end also rises.

That is, the third floor portion 62c and the fourth floor portion 6
2d is bent in a substantially U-shape, and the third and fourth floor portions 64c and 64d of the pair of side floor plates 64 are also interlocked therewith. Therefore, the user whose upper body has been raised can be bent in a U-shaped manner by the third floor portions 62c, 64c and the fourth floor portion 62d,
Since the legs are held in a bent state by 64d, the posture in which the upper body is raised can be easily maintained.

The mounting frame 21, the supporting frame 25 and the floor plate 61 are detachably provided on the base 1, so that they can be removed for carrying. Can be easily performed.

[0078]

As described above, according to the first aspect of the present invention, the rotating frame on which the floor plate is placed is supported by the supporting frame at one end and the other end in the width direction, respectively. And the other end is swingably supported in the ascending direction, and the supporting frame is provided on a base via a vertically driven mounting frame.

Therefore, when the floor plate is swung through the rotary frame, the end of the floor plate in the width direction can be swung without being displaced downward. It is not necessary to secure a space part, so that the supporting height of the floor plate body can be lowered sufficiently so that the patient can easily get on and off the vehicle and does not give anxiety to the patient when changing positions. .

In addition, since the above-mentioned placing frame is provided on the base so that the height can be adjusted, the supporting height of the patient is high in the case of performing a medical examination, nursing, etc. of the patient. If it is better to do so, it can be raised to make the work easier.

According to the second aspect of the present invention, the central floor plate and the side floor plate of the floor plate are integrally formed by a synthetic resin and connected by a thin portion so that the side floor plate can be turned only to the upper surface side. It is possible to prevent the production and assembly work from taking extra time.
