BEST MODE FOR CARRYING OUT THE INVENTION Next, one embodiment of a bed-compatible mattress having a back raising function according to the present invention will be described, and will be described below with reference to the accompanying drawings. FIG. 1 shows the mattress 1. The mattress 1 is provided with a slide sheet 2 at a position corresponding to the user's back of the mattress 1. The slide sheet 2 has a bag portion 2a formed in a loop shape by folding one end side of the slide sheet 2 and sewing at a position near the other end side. The bag portion 2a is opened in the width direction of the mattress 1. is doing. The end side of the bag portion 2a in the slide sheet 2 is attached to a stretchable knit-shaped material 3 provided in the central portion of the mattress 1, and the attachment tool 4 is attached to the other end side of the slide sheet 2.
4 is mounted, together with the involvement of the mattress 1 ends by portions of the other end side of the slide seat 2, the slide sheet 2 other through the fitting 4, 4 to the bottom 5
The ends are attached (see Fig. 2). The core member 6 is inserted into the bag portion 2a of the slide sheet 2 through the opening.

The mattress 1 has a structure in which a core material (not shown) made of a known fibrous substance having a certain degree of rigidity and having resilience, a nonwoven fabric or the like is covered with a surface fabric 7. The mattress 1 has a bendable structure so as to easily follow the displacement of the bottom 5, and the description thereof is omitted here. In this case, the bottom 5 has a structure applicable to one gatch bed, for example, the back bottom 5
a, a waist bottom 5b, a knee bottom 5c, and a foot bottom 5d, and a curved bottom 5e having a structure that bends to one side with an appropriate curvature between the back bottom 5a and the waist bottom 5b, and a knee bottom 5c and a foot bottom. A curved bottom 5f is disposed between the curved bottom 5f and the curved bottom 5f.

As the surface material 7 of the mattress 1, any suitable known material can be applied, and a material having stretchability to some extent and breathability is preferable. The knitted material 3 provided in the middle portion of the mattress 1 is sewn to the surface material 7 of the mattress 1. This knit material 3
Has a structure that is more easily expanded and contracted as compared with the surface material 7 of the mattress 1.

The core member 6 fitted into the slide sheet 2 is made of a material that comes into contact with the inner surface of the slide sheet 2 with low friction. That is, as the core material 6, for example, a structure in which a fluorine resin is laminated on the surface is adopted. The fixture 4 is made of hard synthetic resin and has a hook portion 4a at its tip which can be engaged with the through hole h of the steel back bottom 5a. With the above configuration, the bag portion 2a of the slide sheet 2 along with the user's back portion is slid on the core material 6 and the mattress 1 in the bag portion 2a when raising the back, thereby the mattress 1 in the latter half of the back raising operation. The pressure on the back of the user due to is reduced.

The bed-compatible mattress 1 having the back raising function according to the present invention is constructed as described above, and its operation will be described below. When the drive mechanism is activated to raise the back, a shift A appears between the bottom 5 and the mattress 1 (see FIG. 3). That is, the head-side end surface of the mattress 1 projects from the back bottom 5a end surface. Since the other end of the slide sheet 2 is locked in the through hole h of the back bottom 5a via the hook portion 4a of the fixture 4, the slide sheet 2 is pulled toward the end surface of the back bottom 5a. Here, since the user's back rests on the slide sheet 2, a frictional force against the tensile force acts, but the core material 6 in the bag portion 2a contacts the inner surface of the bag portion 2a in a low friction state. Therefore, the bag portion 2a slides on the core material 6 by the pulling force, and as a result, the slide sheet 2 is substantially displaced A
Minutes, you will have to slide your head on the mattress 1,
It is possible to reduce the deviation in the foot direction of the user.

On the other hand, in the latter half of back raising, the gap between the bottom 5 and the mattress 1 is enlarged to B, and the bag portion 2a of the slide sheet 2 slides on the core member 6,
In the slide sheet 2, the knit-shaped material 3 extends and moves to the side of the mattress 1, and the shift α for escaping the pressing force on the shoulder of the user of the mattress 1 is doubled, and the feeling of pressure on the back can be reduced. Yes (see Figure 4). Thus, when raising the back, the mattress 1 to the slide sheet 2
Since the pressure force applied to the user via the pad is reduced, the stress applied to the contact area of the back with the mattress 1 is reduced, and it is also effective in preventing bed sores due to the obstruction of blood flow. Further, since the compressive force applied from the side of the mattress 1 is reduced, it is possible to prevent the body from being pushed out in the foot direction by repeating the back raising operation.

The bed-compatible mattress having the back raising function according to the present invention can also be configured as follows. In the mattress 10 in this case, constituent elements substantially similar to those of the above-described embodiment are designated by the same reference numerals, and description thereof will be omitted. That is, in the mattress 10 shown in FIG. 5, Oite at positions corresponding to the user back of the mattress 10, the one end side of the sliding seat 11, sewn in place of the 10 horses end surface nearer the mattress,
Fold back on mattress 10 and slide slide
Wrap the other end of the mattress 10 with the back side of the mattress 10 and wrap the end of the mattress 10 with the slide sheet 11.
In this state, the other end of the slide sheet 11 is attached to the back bottom.
Insert the hook portions 4a, 4a of the fixtures 4, 4 into the through hole h of 5a.
And attach it (see FIG. 6). And
The core member 6 is disposed inside the folded back side of the slide sheet 11. With this configuration,
At the time of raising the back, the slide sheet 11 is folded back together with the user's back, and the slide sheet 11 is slid on the mattress 10 via the core material 6 so that the mattress 10 moves to the back of the user in the latter half of the back raising operation. I try to reduce the feeling of pressure.

In this mattress 10, a shift A occurs between the bottom 5 and the mattress 10 at the start of raising the back, while the slide sheet 1 on the side closer to the center of the mattress 10 is formed.
One end side of 1 is about A / 2 (see FIG. 7). Further, in the latter half of back raising, the gap between the bottom 5 and the mattress 10 expands to B, and further the gap α for escaping the pressure force on the shoulder of the user of the mattress 10 is doubled to move toward the center of the mattress 10. The one end side of the side slide sheet 11 is about B / 2 + α, and the feeling of pressure on the back can be reduced (see FIG. 8).

[0013]

According to the present invention, when pressure is applied to the back by the mattress in the latter half of the back raising operation, the slide sheet pressed against the user's back (shoulder) slides on the core material with low friction. By doing so, the slide sheet moves to the head side of the mattress together with the back of the user to release the pressing force, so that the feeling of pressure on the shoulder can be reduced. Further, since the slide sheet moves to the head side of the mattress to reduce the force pushing out the back of the user, it is possible to suppress the movement of the body to the foot side due to repeated back raising operations, Furthermore, since the stress on the user's back is reduced, it is effective in preventing bedsores.
