Description

[0001]
[Industrial applications]
The present invention relates to a mattress that can be comfortably lifted without pressure on the abdomen of the user of the bed when the back is lifted in a bed having a back-raising mechanism used for nursing care and treatment.
[0002]
[Prior art]
The mattress used for the reclining bed is generally a single integrated mattress.In the case of this integrated mattress, the mattress has a thickness at the bending point of the undulation of the back, When the lower surface is bent along the bending point, a force acts in the direction of contraction on the upper surface, and in order to escape from that force, the internal cushion body is pushed forward and the abdomen is squeezed, giving a feeling of cramping There were drawbacks. This became more pronounced as the thickness of the mattress increased. Therefore, as a method of solving this even a little, there is a structure that bends in a curved line as a multi-joint structure of the bending point of the reclining frame, but the point and the frame structure that do not lead to the fundamental solution become complicated, This has led to higher costs.
[0003]
As an attempt to solve the problem with the mattress, there has been a commonly used two-piece type mattress 10. As shown in FIG. 6, the two-piece mattress 10 is divided into a mattress A11 and a mattress B12, and the mattress A11 and the mattress B12 are connected by a connecting portion 13. In this case, the back frame 14 is configured to move so as to bend about the mattress connecting portion 13 as a fulcrum, and to rotate about the mattress connecting portion 13 as a fulcrum. Due to the bending of the mattress, the upper body of the user bends from the waist in a natural manner, thereby eliminating pressure on the abdomen.
[0004]
However, as the frequency of use of the mattress increases, the two-piece mattress 10 has a structure in which the two-piece mattress 10 is connected only by the connection portion 13. There was a disadvantage of being damaged. In addition, since it is divided at the point corresponding to the waist part where the weight ratio of the bed user is the largest, the filling inside the mattress is likely to collapse in shape compared to the undivided mattress However, there is a disadvantage that the sleeping comfort is impaired.
[0005]
[Problems to be solved by the invention]
As described above, an object of the present invention is to provide a mattress that eliminates pressure on a user's abdomen by a mattress during a back-up operation and that is durable for long-term use and does not impair sleeping comfort.
[0006]
[Means for Solving the Problems]
Ri Na than rectangular cushion body, separate from the one end side in the longitudinal direction in the longitudinal direction of the middle or in multi several layers in the rectangular cushion body conforming position on the back frame reclining bed with back-raising mechanism When the separation cushion body is placed and the back frame is raised with the bending point of the bed as a fulcrum, the upper layer cushion body and the lower layer cushion body are in contact with the upper layer cushion body and the lower layer cushion body. A reclining mattress in which an upper layer cushion body is slid so as to protrude from a lower layer cushion body, and a bag body covering the rectangular cushion body has a longitudinal direction from one end side in the longitudinal direction. The bag is divided into several parts according to the rectangular shape of the cushion core body of each layer halfway to form a bag body of each layer and the remaining length part A joining portion where the upper surface and the lower surface of each of the plurality of layers that make up one bag body are in contact with each other and the inner surfaces of both sides of the bag body that is not separated into a plurality of layers are fixed. The reclining mattress , characterized in that the webbing that keeps the position of the mattress is fixed .
[0007]
[Action]
On the back raising side of the reclining bed frame, a cushion body separated into two layers is placed, and when the back frame 14 of the reclining bed frame is raised, the bending point of the back frame 14 of the reclining bed frame is used as a fulcrum, When bent, the lower cushion body starts bending along the bending point of the reclining bed frame. Along with that, the cushion body located in the upper layer starts sliding on the contact surface 27 with the lower layer cushion body by being separated from the lower layer cushion body, and extends from the bending point to the cushion body end. Can be slid upward by a difference in distance between the upper surface and the lower surface. The difference in distance between the upper surface and the lower surface from the bending point due to the slide to the end of the cushion body increases as the thickness of the cushion body increases. Therefore, by having the two-layer cushion body separated as described above, each cushion body is easily bent without applying an excessive force in the direction of contraction to the bending point, and the cushion body is formed at each bending point of each layer. Does not bulge or protrude.
[0008]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, a mattress having a rectangular cushion body, a cushion A21, a cushion B22 and a cushion B22 each extending from one end in the longitudinal direction of the mattress to a length approximately half of the total length in the longitudinal direction. Separated into layers. This is an example in which two layers are provided as an example, and may be separated into multiple layers.
[0009]
FIG. 2 shows the internal structure of a cushion A21 and a cushion B22, which are cut out in an arbitrary part. The upper and lower surface layers are quilted using cotton or the like as a filling material. The length of about 2/3 of the longitudinal direction is divided into two forks corresponding to the rectangular shape of the cushion A21 and the cushion B22 to form a bag A23 and a bag B24, and the remaining length Constitutes one bag C25.
[0010]
In addition, when the bag A23 and the bag B24 are connected to each other at a bifurcated root, the contact surface 27 between the cushion A21 and the cushion B22 may have an arbitrary shape due to the weight of the waist of the bed user in the back-up state. When it is held at the position and the state is shifted from the raised state to the flat state while being held, wrinkles are formed on the respective contact surfaces 27 of the cushion A21 and the cushion B22 by the area A28. (See FIG. 3) Therefore, the roots of the bag A23 and the bag B24 are prevented from being displaced by the repeated bending of the bag A23 and the bag B24 so that the connecting portion 26 of the bag A23 and the bag B24 does not shift. A webbing 30 is sewn to the connecting portion 26 and both inner surfaces 29 of the bag C25. The cushion material inside the bag uses two pieces of solid cotton, but this is not limited to solid cotton, and another cushion material such as urethane foam or latex foam may be used. . The contact surface 27 where the bag A23 and the bag B24 are in contact with each other is made of a slippery material having a low coefficient of friction. The cushion material is inserted into the bag A23, the bag B24 and the bag C25, and the mattress is inserted. In this case, as shown in FIG. 4, the upper cushion A21 is easily slid upward when reclining.
[0011]
FIG. 5 shows another example of the use of the reclining mattress of the present invention. By using a slippery cloth for the contact surface 27 between the cushion A21 and the cushion B22, the cushion mat between the cushion A21 and the cushion B22 is used. By inserting another cushion C31, it is possible to easily improve the sleeping posture, and to make the care receiver take a posture in which the caregiver can easily work when changing diapers or using stool.
[0012]
【The invention's effect】
As described above, according to the present invention, the mattress is separated into the cushion A21 and the cushion B22 at a position suitable for the back frame 14 of the bed having the back-raising mechanism, and the coefficient of friction is applied to the contact surface 27 between the cushion A21 and the cushion B22. When the cushion A21 slides outward in the longitudinal direction of the cushion B22 to eliminate the pressure on the abdomen of the bed user, and when repeatedly performing the back-up state and the flat state, By providing the webbing 30 fixed between the padding inside the cushion A21 and the padding inside the cushion B22, the joint portion 26 can be kept at a fixed position, and the shape of the mattress can be maintained for a long time. And easily insert another cushion C31 between the cushion A21 and the cushion B22. Can, it is possible to be taken the work is easy attitude of the caregiver to the caregiver.
