DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor which does not impose a burden on a user by absorbing a shift generated in a mattress accompanying a floor adjusting operation of a bed (gatch bed) having an adjustable floor. The present invention relates to a mattress corresponding to a bed having a section adjusting function.

[0002]

2. Description of the Related Art At present, beds with adjustable floors (gatch beds) having various mechanisms have been commercialized, and are widely used not only for hospitals but also for home use. When raising the back in such a gatch bed, the user's body receives a force from the bottom because the bent portion on the bottom side of the bed and the bent portion of the body are at different positions. As a result, the body is displaced, and the frictional force applied to the skin surface generated when the body is displaced may cause floor rubbing, or the body (especially the abdomen) may be pressed, resulting in discomfort. Therefore, in order to improve the inconvenience as described above, for example, the bed is configured so that the bent form of the bottom is adapted to the waist and the back of the knee at the bed side, or curved at an appropriate curvature at the bent position. It has been proposed to arrange a bottom to be made. When the mattress M is used for such a bed, as shown in FIG. 5, the mattress M corresponding to the bent position of the bottom applies a force in the direction of contraction to the inside of the bend, and
A force is applied in the direction of extension.

[0003]

For this reason, if the mattress M does not have flexibility, the inside of the bent portion is bent so as to be crushed, and the mattress M can be applied to the bottom of a bed having the above-described function. A highly flexible mattress was required. The present invention has been proposed in view of the above background, and satisfactorily follows the bottom position regardless of the floor adjustment operation of a bed (gatch bed) whose floor can be adjusted, and places a burden on the user. An object of the present invention is to provide a mattress corresponding to a bed having a floor-adjusting function and having a structure not to give.

[0004]

In order to solve the above-mentioned problems, according to the present invention, in the present invention, it is possible to provide a mattress applicable to a bed having a floor adjusting function, which corresponds to a movable adjustable bottom. A mattress corresponding to a bed having a floor adjusting function with an extension adjusting portion that secures an extended portion of the outer side compared to the inner side by expanding the outer layer that is bent in the longitudinal direction at a position where the bending is performed is disclosed. I do. Further, in the present invention, in claim 2, the mattress corresponding to a bed having a floor adjusting function in which the extension adjusting section has a structure in which the degree of extension in the longitudinal direction is increased from the middle layer to the outer layer. I do. Further, in the present invention, in claim 3, the elongation adjusting portion is arranged from the intermediate layer toward the outer layer.
A mattress corresponding to a bed constituted by a plurality of separation layers having a large degree of longitudinal elongation is disclosed. Further, in the present invention, in claim 4, a mattress corresponding to a bed having a floor adjusting function in which a side guard portion is protrudingly provided on a width direction end surface corresponding to the extension adjusting portion is disclosed.

According to the first aspect, when the bottom is adjusted, the mattress at that position reduces the pressure on the inside of the bend by the expansion of the outer layer that bends, and the bent portion is not collapsed. Follow the bottom movement.

According to the second aspect, the bent portion of the mattress extends greatly as it approaches the bent outer surface, and can be bent along the bottom.

According to the third aspect, the bent portion of the mattress extends greatly as the separation layer is closer to the outer surface of the bent portion, and the bent portion can bend in accordance with the displacement of the bottom.

According to the fourth aspect, when the bottom is inclined, the user can be supported from the side of the mattress.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a mattress corresponding to a bed having a floor adjusting function according to the present invention will be described with reference to an embodiment shown in the accompanying drawings. FIG. 1 shows a mattress 1 applicable to a gatch bed. The mattress 1 has a back bottom (to be described later) that can be raised and lowered, and an extension adjusting portion 2 that can expand a bent outer layer in the longitudinal direction at a position corresponding to a position between the waist bottoms. Side guards 3 and 3 are protruded from an end portion in the width direction of the upper surface of the mattress of the extension adjusting portion 2.

The mattress 1 has a structure in which a well-known filling (urethane foam or the like) is covered with a nonwoven fabric, a polyester knit, or a water-repellent cloth member as a surface material.

As shown in FIGS. 2 and 3, the elongation adjusting section 2 comprises a first separation layer 4 and a second separation layer 4 which divide the padding by a predetermined length in the longitudinal direction of the mattress from the intermediate layer to the outer layer. 5 and the third separation layer 6 are slidably stacked on each other. In addition, the first separation layer 4, the second separation layer 5, and the third separation layer 6 can be covered with a low-friction sheet (not shown) so that they can slide easily with each other.
Further, the outside of the extension adjusting section 2, that is, the mattress 1
The lower surface may be covered with a stretchable and low-friction sheet S as indicated by a virtual line.

The side guard 3 has a function of supporting the user from the side of the mattress. However, when the mattress 1 is bent as shown in FIG. Has a repulsive force that can oppose the compressive force to some extent. This prevents the upper surface of the mattress 1 from bending and bending, thereby securing a space on the upper surface of the mattress 1. Therefore, a relatively hard urethane foam or the like can be used as the filling for the side guard 3. In addition, side guard 3
May be configured integrally with the mattress 1,
It may be configured to be detachable.

The mattress 1 corresponding to the bed having a floor adjusting function according to the present invention is constructed as described above. The mattress 1 is placed on a well-known gatch bed 10 shown in FIG. The operation when the device 10 is operated will be described. In this case, the gatch bed 10 has a divided bottom 11, that is, a back bottom 11a corresponding to the back, and a curved bottom 11c that curves at an appropriate curvature from the back bottom 11a to the waist bottom 11b corresponding to the waist. ing.

When the user lies down on the mattress 1 and operates the gatch bed 10 to raise the back, the back bottom 11 rises and is supported by the curved bottom 11c from the back bottom 11a to the waist bottom 11b. As shown in FIG. 2, the extension adjusting section 2 of the mattress 1 has the first separation layer 4, the second separation layer 5, and the third separation layer 6, and the degree of elongation increases toward the outside of the lower surface of the mattress 1, and is independent of each other. And slide to develop an arc. At this time, if the lower surface of the mattress 1 is provided with the stretchable and low-friction sheet S, the first to third separation layers 4 to 6 are not separated. As the back bottom 11 is inclined, the weight of the user shifts to the waist bottom 11b side.
The sliding resistance between the three separating layers 4 to 6 further decreases, and the sliding layers smoothly slide with each other.

As described above, when the outer surface of the lower surface of the mattress 1 is bent in the longitudinal direction by the expansion of the extension adjusting portion 2, the upper surface of the mattress 1 is compressed as indicated by an arrow. However, since the side guard 3 has a repulsive force capable of opposing the compressive force, the upper surface side of the mattress 1 is prevented from bending due to bending, and a space on the upper surface side of the mattress 1 can be secured. It is possible to bend substantially following the shape of the curved bottom 11c. Thereby, the mattress 1 is provided to the user side.
This reduces the pressure from the patient, and does not cause discomfort in the abdomen or the like and does not cause bedsores, thereby providing a comfortable bed life.

[0016]

As described above, according to the present invention, even in a specially designed gatch bed, sufficient followability can be provided, and a comfortable use can be obtained.
