DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress device suitable for a back-up type bed device and a rising type bed device using the mattress device.

[0002]

2. Description of the Related Art In a bed apparatus for a sick person, a so-called wake-up bed apparatus is sometimes used to assist a patient with reduced physical strength to raise his / her upper body when eating. The wake-up type bed device divides a floor plate provided on an upper surface of a bed frame into a plurality of floors in a longitudinal direction of the bed frame, and a floor portion corresponding to an upper body of a user. The back floor portion can be driven up and down by a drive mechanism.

[0003] Therefore, if the back floor is driven in the upright direction, a patient who lies on the floor board via a mattress can raise his / her upper body with little physical strength.

[0004] Conventionally, the above-mentioned floor plate body is, in addition to the above-mentioned back floor portion,
It has a fixed floor fixed to the bed frame, and one end of the back floor is rotatably connected to the fixed floor.

[0005] Therefore, when the above-mentioned back floor is driven by the drive mechanism in the upright direction in order to raise the patient's upper body, the back floor is rotated up in the upright direction about the connection with the fixed floor as a fulcrum. Become.

[0006] When the backfloor is turned up in the upright direction, the mattress placed on the floor plate is bent while pressing the back of the patient. Because the mattress has a predetermined thickness, when it is bent along with the standing of the back floor portion, a compressive force is generated along the inside in the longitudinal direction on the upper surface which is inside the curve, and the lower surface which is the outer surface. Generates a tensile force along the outside in the longitudinal direction.

Therefore, a compressive force generated on the upper surface of the mattress also acts on the back surface of the patient whose upper body is raised while being pressed by the upper surface of the mattress. The buttocks can be pulled back (inside the curve), causing pressure on the body, especially the abdomen.

It is good if the patient has physical strength and can lift the back of the body from the upper surface of the mattress by himself and remove the compressive force acting on the back, but if the patient does not have enough physical strength, the compressive force should be reduced. It may not be able to be removed on its own, in which case the patient may suffer more.

[0009]

As described above, in the conventional wake-up type bed apparatus, when the back floor is raised in the upright direction, the upper surface of the mattress placed on the floor plate presses the back of the patient. While being bent, a compressive force is generated on the upper surface of the mattress from both ends in the longitudinal direction toward the inside in the longitudinal direction, and the compressive force acts strongly on the back of the patient.

[0010] Therefore, the compression force applied to the back of the user cannot be removed unless the user lifts the body from the mattress by himself / herself, so that the user's body, especially the abdomen, is pressed when raising his / her back, which gives the user discomfort. In particular, if the user is a sick or elderly person and the body is lifted from the upper surface of the mattress and the compressive force applied to the body cannot be removed by itself, the pain given to the user may be increased.

An object of the present invention is to provide a mattress device capable of reducing a compressive force generated on an upper surface when being bent. SUMMARY OF THE INVENTION It is an object of the present invention to provide a wake-up bed device capable of reducing discomfort and pain given to a user by reducing a compressive force acting on the back of the user when raising the back.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a wake-up type bed apparatus 1, which is provided with a base 2. The base 2 is formed in a rectangular frame shape, and casters 3 with stoppers are provided at four corners on the lower surface thereof.

A bed frame 4 is provided on the upper surface side of the base 2. A head board 5a is provided upright at one end of the bed frame 4 in the longitudinal direction, and a foot board 5b is provided upright at the other end.

On the upper side of the bed frame 4, a floor plate 6 is provided. The floor plate 6 is divided into five along the longitudinal direction of the bed frame 4, and the center is a fixed floor plate portion 7 fixed to the bed frame 4. On the headboard 5a side of the fixed floor plate portion 7, a waist floor plate portion 8 and a back floor plate portion 9 are sequentially rotatably connected.
On the footboard 6 side of the fixed floor plate 7, a first leg floor plate 11 and a second leg floor plate 12 are sequentially rotatably connected.

The bed frame 4 is provided with a driving device 13. The driving device 13 has a case 14, and a driving motor 15 is provided on one side of the case 14. A first drive shaft 16 is provided at one end of the case 14 on the headboard 5 side, and a second drive shaft 17 is provided at the other end of the footboard 5b. The first drive shaft 16 and the second drive shaft 17 are rotated in the directions indicated by arrows in the figure by the operation of the drive motor 15.

A first arm 18 is mounted on the first drive shaft 16.
One end of a second arm 19 is fixed to the second drive shaft 17. A pair of first rollers 21 are rotatably provided at the other end of the first arm 18, and the first rollers 21 are cross sections provided on the back surface of the back floor plate 9. It is rollingly engaged with the U-shaped guide member 22. At the other end of the second arm 19, a second roller 23 is rotatably provided.
Numeral 4 contacts the lower surface of the first leg floor plate 11.

When the first arm 18 is driven in the upright direction by the operation of the drive motor 15, the back floor plate 9
Are rotated by the first roller 21 in the upright direction, and the waist floor plate 8 is interlocked with the rotation of the back floor plate 9.

When the second arm 19 is driven in the upright direction by the operation of the drive motor 15, the second roller 2 is driven.
3, the first leg floor plate 11 rotates in the ascending direction with the connection end with the fixed floor plate 7 as a fulcrum. Since the second leg floor plate portion 12 is interlocked with the elevation of the first leg floor plate portion 11, the leg floor plate portions 11 and 12 are bent in a substantially U-shape.

The mattress device 3 is provided on the upper surface of the floor plate 6.
1 is placed. The mattress device 31 is configured such that each floor plate portion of the floor plate body 6 is curved in accordance with the undulating drive by being driven up and down, and the compressive force generated on the upper surface inside the curve at the time of the bending is reduced. The structure is reduced.

That is, the mattress device 31 is similar to that shown in FIG.
As shown in (a) and (b), an inner body 32 and a bag-shaped outer body 33 covering the inner body 32 are provided. The inner body 32 is composed of a pair of first layered members 34 divided and laminated to have substantially the same thickness, and a second layered member 35 to which the first layered members 34 are joined on upper and lower surfaces. It has a layer structure.

The first layered member 34 is relatively soft,
A material having a cushioning property, for example, hard cotton molded into a rectangular sheet or urethane foam in a semi-rigid sheet is used.

The second layered member 35 is harder than the first layered member 34, has a smooth surface, and slides with the first layered member 34 joined to the upper and lower surfaces thereof. It is formed in a rectangular sheet shape using a material that is easy to use, such as a foamed polyester. Further, in order to make the second layered member 35 easily bendable, cutouts 36 along the width direction are formed at predetermined intervals in the lengthwise direction on the upper and lower surfaces in the middle in the lengthwise direction.

The first layered member 34 and the second layered member 35 which have been joined are bonded and fixed by an adhesive 37 at the center of the longitudinal direction, which is shifted from the place where the notch 36 is formed.

Thus, when the inner body 32 is bent at a middle portion in the longitudinal direction where the cutout 36 of the second layered member 35 is formed, the cutout 3
The first layered member 34 and the second layered member 35 on the one end side located on the 6 side, that is, the side to be curved, bend while sliding on each other due to the difference in curvature.

The exterior body 33 covering the interior body 32
Is formed of a fabric that expands and contracts according to the curvature of the interior body 32. Therefore, the exterior body 32 does not hinder the smooth bending of the interior body 32.

FIG. 3 shows one end of the inner body 32 in the longitudinal direction.
As shown in (a), a long and narrow hole 38 penetrating in the thickness direction is formed along the longitudinal direction. A string-shaped member 39 is passed through the long hole 38, and both ends thereof are connected to a button 41 on the outer surface of the exterior body 33.

Accordingly, the string-like member 39 regulates the first layer-like member 34 and the second layer-like member 35 of the interior body 32 from shifting in the width direction, and FIG.
As shown in FIG. 7, when the respective layered members 34 and 35 slide in the longitudinal direction, the long holes 38 do not hinder the movement.

The mattress device 31 is mounted on the floor plate 6 of the bed device 1. In that case, the mattress device 31 positions the notch 36 formed in the second layered member 35 of the interior body 32 at a position corresponding to the waist floor plate portion 8,
One end in the longitudinal direction in which the long hole 38 is formed is provided so as to correspond to the back floor plate portion 9 side.

In the wake-up type bed apparatus 1 having the above configuration,
When raising the upper body of the user U who lies on the mattress device 31, the drive motor 15 is operated to activate the back floor plate portion 9.
Up. As a result, the waist floor plate portion 8 is linked to the rise of the back floor plate portion 9, so that the user U is raised up as shown in FIG.

When the back floor plate portion 9 and the waist floor plate portion 8 are raised, the mattress device 31 is bent by the raising. The interior body 32 of the mattress device 31 has a three-layer structure including a pair of a first layered member 34 and a second layered member 35.

Therefore, at the time of bending, the second layered member 35 located below the first layered member 34 located on the upper surface side is bent with a larger curvature, and the lower side of the second layered member 35 is further bent. Is curved with a larger curvature. At this time, the second layered member 35 is formed of a material having lubricity.
The pair of first layered members 34 joined to the upper and lower surfaces of the layered member 35 slide.

The first layered member 34 and the second layered member 35 slide relative to each other during bending, so that the first layered member 34 and the second layered member 35 are approximately one-third the thickness of the inner body 32 and are located on the upper side. Only the compressive force generated in one layered member 34 acts on the back surface of the user U. The smaller the thickness, the smaller the compressive force generated during bending. Therefore, the compressive force applied to the back surface of the user U is sufficiently smaller than the thickness of the mattress device 31, so that the discomfort and pain given to the user U are greatly reduced.

Since the exterior body 33 covering the interior body 32 is made of stretchable fabric, the mattress device 3
When bending 1, the exterior body 33 does not hinder the curvature of the interior body 32.

The present invention is not limited to the above embodiment, but can be variously modified. For example, the second layered member 3
Instead of forming the lubricating member 5 from a lubricating material, as shown in FIG. 4, a lubricating lubricating material such as satin is provided between the first layered member 34 and the second layered member 35. By interposing the sex sheet 45, the first layered member 34 and the second layered member 35 may be easily slidable. In this embodiment, the lubricating sheet 45 is fixedly joined to the first layered member 34, but the second layered member 3
5 or may be simply interposed when the lubricating sheet 45 is relatively rigid.

Further, according to the present invention, the first layered member 34
The second layered member 35 and the second layered member 35 may be connected by a connecting thread 46 as shown in FIGS. 5A and 5B instead of bonding and fixing the middle part in the longitudinal direction with an adhesive.

Although not shown, the interior body may have a two-layer structure in which one first layered member and one second layered member are joined together. In order to reduce the compressive force, it is desirable that the upper first layered member is made as thin as possible. For example, in the case of a three-layer structure, the upper first layered member is made sufficiently thin to act on the user. Even if the compression force is reduced, the cushion performance of the entire interior body can be maintained by the first layered member located on the lower side.

[0046]

According to the first aspect of the present invention, when the interior body is divided into a first layered member and a second layered member having a predetermined thickness, and the interior body is curved, the first body is bent. The layered member and the second layered member are separately curved while sliding relative to each other in a state thinner than the entire thickness of the interior body.

As a result, the thickness of the upper layered body of the inner body can be made sufficiently thinner than the thickness of the entire inner body, so that the upper layered member is generated when the inner body is curved. Compressive force can be reduced.

According to the second aspect of the present invention, since the surface of the second layered member has lubricity, when the interior body is bent, the first layered member and the second layered member slide. And bend separately. Therefore, the compressive force generated on the surface of the first layered member is not affected by the thickness of the second layered member.

According to the third aspect of the present invention, the lubricating sheet is provided between the first layered member and the second layered member. The first layered member and the second layered member slide and bend separately. Therefore, also in this case, the compressive force generated on the surface of the first layered member is not affected by the thickness of the second layered member.

According to the fourth aspect of the present invention, the inner body is provided with the second
Since the first layered member has a three-layer structure in which the first layered member is laminated on the upper and lower surfaces of the layered member, the first layered member can be thinned even when a sufficient thickness as a mattress device is secured. The compressive force generated in the one layered member can be reduced.

According to the fifth aspect of the present invention, a mattress device having a small compressive force generated on the surface during bending is used for the wake-up type bed device. Therefore, when the user raises the floor of the floorboard and raises the upper body of the user, the compressive force acting on the back of the user can be reduced, so that discomfort and pain given to the user can be reduced.
