Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed apparatus suitable for the sick.

[0002]

2. Description of the Related Art A patient who cannot turn over or wake up by himself must stay in a supine position for a long period of time. In this way, if the patient remains in a supine position for a long period of time, so-called bed sores occur, which increases the patient's pain. Therefore, the posture of the patient must be appropriately changed to prevent bed sores.

In order to be able to appropriately change the posture of the patient, the applicant of the present application has proposed a bed apparatus disclosed in Japanese Patent Publication No. 2-44225. This bed apparatus has a bed main body, and the bed main body is provided with a rotation supporter rotatably supported at the center in the width direction. The rotary support is provided with a floor plate. In this floor plate body, side floor plates are connected to both sides of a central floor plate so as to be rotatable only in an upward direction.

When the rotary support is rotated in the left-right direction with the center in the width direction as a fulcrum, the lateral floor plate on one end in the width direction, which descends, hits the stopper body and rotates downward. Is blocked, it bends upward. As a result, the patient lying on the central floorboard is changed in position according to the rotation of the central floorboard, and is prevented from falling from the floorboard body by the lateral floorboard bent upward. Therefore, bed rotation can be prevented by alternately rotating the rotary support in the left-right direction to change the body position.

By the way, in the bed apparatus having the above-mentioned structure, when the body position of the patient is changed, the center floor plate of the floor plate is rotated by swinging the rotary support body in the left-right direction with the center in the width direction as a fulcrum. It is designed to interlock with the rotation of the support.

Therefore, the rotary support has a pivotal movement in which one of the left and right sides is raised with the center in the width direction as a fulcrum and the other is lowered, and the central floor plate is interlocked with the pivotal movement. There is.

As described above, when the rotary support is rotated about its widthwise center as a fulcrum, a sufficient space must be secured on the lower surface side of the rotary support so that one end in the widthwise direction can rotate downward. I have to. For that purpose, the height of the bed main body, that is, the support height of the central floor plate with respect to the bed main body must be increased.

If the support height of the central floorboard is increased, it may be difficult for the user to get on and off the upper surface of the central floorboard. Especially, if the user is sick, he may not be able to get on and off by himself, which is very inconvenient. . Therefore, the lower the supporting height of the floor plate provided on the bed body is, the easier it is for the patient to get on and off.

In addition, when a supine patient undergoes medical examination or nursing care, it may be difficult to perform medical examination or nursing care if the height of the supine patient is too low. It is desirable to be able to change the height.

[0010]

As described above, in the conventional bed apparatus, when the posture of the patient is changed, one end side in the width direction of the central floor plate forming the floor plate body is raised and the other end side is lowered. Since it is configured to rotate, it is necessary to secure a space on the lower surface side of the central floor plate that can lower the other end side in the width direction of the central floor plate. Therefore, the support height of the floor plate becomes high, and the patient may not be able to get on and off on his own, making it difficult to use.

Further, when examining or caring for a supine patient, it is sometimes desired to change the supporting height of the patient. However, a conventional bed apparatus capable of changing the patient's posture has not been developed so far as it can change the supporting height of the patient.

A first object of the present invention is to make the floor plate support height sufficiently low so that a patient can easily get in and out of it.
It is an object of the present invention to provide a bed device that can be swung in the left-right direction so that the posture of a patient can be changed.

A second object of the present invention is to not only make it possible to make the supporting height of the floor plate sufficiently low to swing it in the left-right direction, but also to adjust the supporting height of the floor plate. The purpose is to provide a bed apparatus that enables the above.

[0014]

A first means of the present invention is to provide a mounting frame, a central floor plate, and a pair of side portions rotatably connected to both sides of the central floor plate only in an upward direction. A floor plate made of a floor plate and placed on the above-mentioned placing frame, and one side connected to one end side of the central floor plate provided on the above-mentioned placing frame with one end side in the width direction as a fulcrum. A first left-right link mechanism that bends the partial floor plate upward and rotates together with the other side floor plate provided on the other end side in the width direction, and the central floor plate provided in the mounting frame described above in the width direction. A second side floor plate, which is connected to the other end side with the other end side being a fulcrum, is bent upward and is rotated and raised together with the one side floor plate provided on the one end side in the width direction.
And a left and right link mechanism.

A second means of the present invention is to provide a base, a mounting frame provided on the base so as to be vertically movable by an up-and-down link mechanism, a central floor plate and both sides of the central floor plate. A floor plate body composed of a pair of side floor plates rotatably connected only in the upward direction, and a floor plate body mounted on the mounting frame, and the central floor plate provided on the mounting frame in the width direction. A first left-right link mechanism that bends one side floor plate connected to the one end side with the one end side as a fulcrum upward and rotates and raises it together with the other side floor plate provided on the other end side in the width direction, One side provided on one end side in the width direction while bending the other side floor plate provided on the above-mentioned mounting frame and connected to the other end side with the other end side in the width direction of the central floor plate as a fulcrum A second left and right link mechanism for rotating and raising together with the floor plate Characterized by comprising.

[0016]

According to the first means, the central floor plate of the floor plate is rotated in the upward direction by the first link mechanism or the second link mechanism with one end side or the other end side in the width direction as a fulcrum. Therefore, in order to rotate the floor board, it is possible to rotate the floor board at a low position without securing a space therebelow. According to the second means, the floor plate can be rotated at a low position, and the supporting height of the floor plate can be adjusted.

One end side in the width direction of the 6a side is rotated in a direction in which the other end side rises with the one end side as a fulcrum.

A floor plate 61 is provided on the upper surface side of the support frame 25. As shown in FIG. 5, the floor plate 61 is connected to a central floor plate 62 having a size substantially corresponding to the rotary frame 32, and hinges 63 on both sides of the central floor plate 62 so as to be rotatable only in an ascending direction. It is composed of a pair of side floor plates 64. A plurality of floor plates 62, 64 are provided, and in this embodiment, four floor portions 62a, that is, first to fourth floor portions 62a.
~ 62d, 64a ~ 64d, each floor board 62, 6
The floor portion 4 has 62a and 64a rotatably connected to each other. Further, only the second floor portion 62b of the central floor plate 62 is detachably fixed to the rotary frame 32.

The hinge 63 is formed by bending a belt-like plate to form a loop having a curved portion 64a at one end and a vertical portion 64b at the other end, as shown in FIG. 7, and one end portion of the vertical portion 64b. The short tube 64c provided on the upper part is composed of a pair of metal fittings 65 rotatably connected by a pivot 64d.

Is connected and fixed to a pipe at one widthwise end of one side floor plate 64.

When the side floor plate 64 is substantially horizontal with respect to the central floor plate 62, the hinge 63 joins the vertical portions 64b of the pair of metal fittings 64, whereby the side floor plate 64 is brought into contact with the central floor plate 62. On the other hand, further downward rotation is prevented. That is, the side floor plate 64 can freely rotate upward with respect to the central floor plate 62, but cannot rotate downward with respect to the horizontal state.

The pair of side floor plates 64 can be folded from the state shown by the solid line in FIG. 8 to the upper surface side of the central floor plate 62 as shown by the chain line. In the folded state, there is a difference in dimension H between the fulcrum to which the floors of the central floor plate 62 are connected and the fulcrum to which the floors of the side floor plate 64 are connected.

Therefore, even if the floor portion of each floor plate 62, 64 is divided into corresponding lengths, the folded floor plate body 6
Since 1 does not bend from the position of the second hinge 65, it is convenient for carrying around.

When the rotating frame 32 is rotated by the first link mechanism 25a or the second link mechanism 25b and the central floor plate 62 of the floor plate body 61 is interlocked with the rotation, the rotary frame 32 is located on the ascending direction side. One side floor plate 64 is maintained in the same plane as the central floor plate 62, and the other side floor plate 64 located on the lower end side is prevented from rotating downward by the stopper shaft 31, It is bent at a predetermined angle to the upper surface side of the central floor plate 62. As a result, the user lying on the floor plate 61 is laterally rotated (raised) by the central floor plate 62 that rotates in the left-right direction, and at the same time, the side portion that bends to the upper surface side of the central floor plate 62. The floor plate 64 prevents the user from falling off the floor plate body 61.

As shown in FIG. 4, the pair of horizontal rods 26 provided on the middle portion of the support frame 25 in the longitudinal direction undulates the floor portions 61a and 64a of the floor plates 62 and 64 of the floor plate body 61, respectively. An up-and-down drive mechanism 71 is provided to allow the movement. The undulating drive mechanism 71 includes a box 72 containing a power transmission mechanism (not shown), a pair of drive sources 73 provided on one side surface and the other side surface of the box 72, respectively.
A first rotating shaft 74 is provided on one end side of the box 72 so as to project both end portions from both side surfaces thereof, and is rotationally driven by the one drive source 73, and both end sides of the box 72 are provided on the other end side thereof. A second rotary shaft 75 which is provided so as to project and is rotationally driven by the other drive source 73. Both ends of the rotary shafts 74 and 75 are rotatably supported by brackets 76 provided on the horizontal rod 26.

One end of a first lifting arm 77 is fixed to both ends of the first rotary shaft 74, and a second rotary shaft 75 is provided.
One end of a second push-up arm 78 is fixed to both ends of the. Rollers 79 are rotatably provided at the other ends of the push-up arms 77 and 78, respectively. A roller 79 provided on the first lifting arm 77 is a pair of first rolling contact plates provided along the longitudinal direction of the first floor portion 62a of the central floor plate 62 shown in FIG. The roller 79 provided on the second push-up arm 78 is rotatably contacted with the upper part 81, and a pair of second rolls 79 are provided along the longitudinal direction of the third floor portion 62c of the central floor plate 62. It is adapted to roll on the rolling contact plate 82.

Each roller 79 has each rolling contact plate 81, 82.
When the first rotary shaft 74 is rotationally driven in a state of being in contact with the first push-up arm 77 in the ascending direction,
The first floor portion 62a of the central floor plate 62 is raised in the standing direction, and the first floor portions 64a of the pair of side floor plates 64 are also interlocked with it.

When the second rotating shaft 75 is rotationally driven to rotate the second pushing arm 78 in the ascending direction,
The third floor portion 62c of the central floor plate 62 is rotated in the upright direction, and the fourth floor portion 62d is interlocked with the third floor portion 62c, so that these bend in a V shape. When the third and fourth floor parts d of the central floor plate 62 rotate, the third and fourth floor parts 64c and 64d of the pair of side floor plates 64 also interlock with it.

Next, the movement of the bed apparatus having the above structure 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 movements of the undulating movement of some floors can be performed.

In order to perform the vertical movement, the vertical drive mechanism 13 is operated and the drive shaft 15 thereof is driven in the protruding direction. Thereby, the levers 6 provided at both ends of the mounting shaft 2 can be raised from the lying state via the pair of rotating shafts 5, so that the mounting frame 2 can be moved according to the rotation of the levers 6.
You can raise 1.

Since the supporting frame 25 on which the floor plate 61 is placed is provided on the upper surface side of the above-mentioned placing frame 25, these are raised in conjunction with each other. In other words, the height of the floor plate 61 can be adjusted so that the patient lying on the floor plate 61 can be easily cared for or examined, and the height of the floor plate 61 can be adjusted by the patient. When getting on and off, it is easy to get on and off by making the floor plate 61 sufficiently low.

In order to rotate the floor plate 61 in the width direction, the first left / right drive mechanism 42 or the second left / right drive mechanism 44 is operated to operate the first left / right link mechanism 35a or the second left / right link mechanism. The mechanism 35b is driven. When the first left / right link mechanism 35a is driven by the first left / right drive mechanism 42 and the first base shaft 36a is rotated counterclockwise as indicated by arrow e in FIG. 3B, the rotary frame 32 is rotated. Is pivotally raised at the other end in the width direction with the roller 51 engaged with the guide 53 at one end in the width direction on the second base shaft 36b side as a fulcrum.

When the rotating frame 32 rises on the other end side with one end side in the width direction as a fulcrum, the floor plate 61 interlocks with the rotation. That is, in the floor plate 61, as shown by the chain lines in FIGS. 3A and 3B, the central floor plate 62 rises at the other end with one end in the width direction as a fulcrum, and is thereby connected to the one end in the width direction. One side floor plate 64 contacts the stopper shaft 31 and bends upward, and the other side floor plate 6 connected to the other end side.
4 and the central floor plate 62 are coplanar with and interlock with each other.

When the second left / right link mechanism 35b is driven by the second left / right drive mechanism 44 and the second base shaft 36b is rotated in the direction of arrow f, the rotary frame 32 is moved in the opposite direction. It can be rotated.

Therefore, by alternately driving the first left / right drive mechanism 42 and the second left / right drive mechanism 44, the central floor plate 62 of the floor plate body 61 can be rotated left and right by the rotary frame 32. it can.

By rotating the central floor plate 62 left and right at predetermined intervals, the posture of the user lying on the floor plate 61 can be converted to left and right. As a result, it is possible to prevent a user, such as a sick person or an elderly person, who has to lie on his / her back for a long period of time, from getting a floor slump, and one side in the width direction that is the base end side of the rotating center floor plate 62. The side floor plate 64 connected to the upper part bends upward, and the floor plate body 61 becomes substantially L-shaped, so that the user whose posture is changed leftward or rightward falls from the floor plate body 61. Is prevented.

In this way, when the body position of the user lying on the floor plate 61 is changed, the central floor plate 62 is driven in a direction in which the other end side rises with one end side in the width direction as a fulcrum.
Therefore, the one end in the width direction, which is the lower end side of the rotating central floor plate 62, is not displaced downward and the central floor plate 6 is not moved.
Since 2 can be rotated, even if the supporting height of the floor plate 61 is sufficiently lowered, the central floor plate 62 can be rotated in the left-right direction to change the posture of the user.

When the center floor plate 62 is rotated in the left-right direction to change the body position of the user, if the support height of the floor plate body 61 is high, the user may feel uneasy. It is better to do in.

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

In order to raise the floor plate body 61 back up, the floor plate body 61 is made horizontal and the undulating drive mechanism 71 is operated. That is, the pair of drive sources 73 are operated to rotate the first rotary shaft 74 and the second rotary shaft 75, and the lifting arms 77 and 78 are interlocked with them.

When the first pushing arm 77 is driven in the ascending direction, the first floor arm 62 of the central floor plate 62 is moved as shown by the chain line in FIG.
The floor portion 62a of the pair rises and the first floor portions 64a of the pair of side floor plates 64 also interlock 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 second floor of the third floor portion 62c of the central floor plate 62 is moved to the second position.
Since one end connected to the floor portion 62b of the second end rotates in a direction in which the other end side rises, the fourth end connected to the other end
The one end side of the floor portion 62d also rises. That is, the third floor 62c and the fourth floor 62d are bent in a substantially V shape,
In addition, the third and fourth floor portions 64c of the pair of side floor plates 64,
64d also works together. Therefore, the user whose upper body is erected can move the third floor 62c, 64 bent in a V-shape.
Since the legs are held in a bent state by c and the fourth floor portions 62d and 64d, it is possible to easily maintain the posture in which the upper body is raised.

The mounting frame 2 is attached to the base.
1. Since the support frame 25 and the floor plate 61 are detachably provided, it is possible to easily carry such as transportation by removing them.

The present invention is not limited to the above-mentioned one embodiment and can be variously modified. For example, in the above-described embodiment, the mounting frame is provided so as to be movable up and down with respect to the base by means of an up-and-down link mechanism, and the supporting frame to which the floor plate is attached is connected to the mounting frame. By doing so, the floor plate can be moved up and down.
The floor plate may be vertically movable by an up-and-down link mechanism, or the floor plate may be vertically moved by directly mounting the floor plate on the mounting frame.

Further, in order to rotate the central floor plate of the floor plate body to the left and right, a rotation frame is rotatably provided on the support frame and is rotated by the first and second left and right link mechanisms. However, the guide 5 in which the roller 51 engages with the lower surface of the central floor plate
3 may be provided and the central floor plate may be directly rotated right and left by the first and second left and right link mechanisms. That is,
The central floorboard can be rotated to the left and right without the rotating frame. In that case, the up-and-down mechanism may be configured to directly move the supporting frame up and down, or there is no supporting frame and the mounting frame is vertically movable on the base. Either of them may be used.

[0056]

As described above, according to the present invention described in claim 1, the frame is provided with a central floor plate and a pair of sides rotatably connected to both sides of the central floor plate only in an upward direction. A floor plate body including a partial floor plate is provided, and a first left / right link mechanism and a second left / right link mechanism are provided in this frame.
With these link mechanisms, the central floor plate is rotated in the direction in which one end side or the other end side in the width direction thereof is a fulcrum, and the other end side or one end side in the width direction is raised, and at that time, the center of rotation of the central floor plate is rotated. The side floor plate provided on the end side was bent upward.

Therefore, not only can the posture of the user lying on the floor plate be changed, and the user can be turned over.
Since the user's body position can be changed without displacing the central floorboard or the side floorboard almost downward, the support height of the floorboard can be made sufficiently low so that the user can easily get on and off. .

According to the second aspect of the present invention, not only can the supporting height of the floor plate for changing the user's body position be sufficiently low so that the user can easily get in and out of the floor plate, The support height of the floor board can be changed.

Therefore, usually, the height of the floor board can be set sufficiently low so that the user can easily get on and off, and the user lying on the floor board can receive nursing care or medical examination. If you get any of these,
The support height of the floor board can be adjusted.
