[Technical field to which the invention belongs]

 The present invention relates to a mattress for a nursing care bed, a mattress having a moderate compressive strength and a cushioning property, and having a soft bending performance so as to easily follow a floor bending, and a cushioning material used for such a mattress. About.

[0002]

[Prior art]

 At present, nursing care beds and mattresses are subject to lending of welfare equipment, and can be rented as nursing care equipment that can be used with nursing care insurance. This is because it is necessary for the cared person to live as independent and comfortable as possible, and to reduce the burden on the cared person. Conventionally, there is a nursing bed with a raised / lowered floor, which hits the back to make it easier for the cared person to take up a comfortable posture when eating or taking a comfortable posture. The so-called back raising function, which inclines the floor, and the care of the caretaker when changing the underwear, etc. It had a so-called foot-raising function that bent parts. There has been proposed a mattress for a patient provided with a slit for bending in order to follow such a bending of the floor surface (Japanese Utility Model Laid-Open No. 3-67623), and further, an invention in which the width of the groove is 20 to 40 mm. (Patent No. 291277) and the like have been proposed. However, in recent nursing care beds, not only the floor is bent, but also the deformation can be adjusted delicately according to the body.There is no conventional mattress that easily follows the deformation of the floor. . Although the invention of Japanese Utility Model Laid-Open Publication No. 3-67623 proposes a slit for bending, it does not specify what kind of slit shape should be obtained to obtain a preferable mattress, so that it is easy to deform the floor surface. It was not a device to follow. On the other hand, Japanese Patent No. 29124777 proposes an invention in which the width of the upper portion of the groove is 20 to 40 mm, but such a shape lacks local softness against bending, so that the floor is easily deformed. Could not be provided with a mattress that would follow.

[0003]

[Problems to be solved by the invention]

 The present invention has been made to eliminate the above-mentioned drawbacks of the prior art, and is intended for nursing care beds having a soft bending performance so as to easily follow a subtle bending of a floor surface while having a moderate compressive strength and a cushioning performance. An object of the present invention is to provide a mattress and a cushioning material used for such a mattress. In addition, by providing such a mattress, the care receiver can easily take a posture that fits his or her body in the event that the care receiver gets up or swells and gets tired. The purpose is to enable a comfortable life for the caregiver. In addition, by providing mattresses that can easily take a comfortable posture that is suitable for the care recipient's body, the care recipient can replace underwear etc. by themselves, enabling the care recipient to become independent In addition, the burden on the caregiver should be reduced by making it easier to perform care such as changing underwear etc., so that both the cared person and the caregiver can live a comfortable life.

[Means for Solving the Problems]

 It is a cushioning material used for a mattress for a nursing care bed, having a width of 750 to 900 mm, a length of 1900 to 2000 mm, and a thickness of 80 to 100 mm. The material of the cushioning material is not particularly limited, and a nonwoven fabric made of natural fiber, synthetic fiber, or the like is preferable. Then, grooves are provided on the upper surface and the lower surface at a pitch of 80 to 110 mm, respectively. The grooves are provided so as to be shifted from each other by a half pitch on the upper surface and the lower surface. If the pitch of the groove portions is too large, the overall flexibility is lacking. If the pitch is too small, a preferable R-shaped portion cannot be obtained and the local flexibility is lacking. The groove part is composed of a slit part with a slit width of 5 mm and a depth of 35 to 45 mm, and two R parts sandwiching the slit part. The radius of the R part is 18 to 27.5 mm, and the total width of the groove part is 41 to 60 mm. To do. If the entire width of the groove is too small, the radius of the R portion becomes small, resulting in a lack of local flexibility, and if the total width of the groove is too large, a part of the body enters the groove, causing a feeling of strangeness. It is. Furthermore, a mattress for a nursing care bed, in which the cushion material described above was covered with a covering material, was used.

[Embodiment of the invention]

 Hereinafter, the present invention will be described based on an embodiment shown in the drawings. The cushion material 1 according to the present invention has a width A of 850 mm, a length B of 1930 mm, and a thickness C of 80 mm. The material of the cushion material 1 was a non-woven fabric composed of 70% polyester and 30% polypropylene (each by weight). On the upper surface 2, a total of 13 grooves 5 were provided with the pitch D of the grooves 5 being 340 mm from the end face 4 as the center of the first groove 5 and the pitch D of the grooves 5 being 100 mm. On the other hand, a total of thirteen grooves 5 are provided on the lower surface 3 with the pitch D of the grooves 5 being 100 mm with 390 mm from the end face 4 as the center of the first groove 5. By doing so, the grooves 5 provided on the upper surface 2 and the lower surface 3 are shifted from each other by a half pitch. Also, the reason why the grooves 5 were not provided at both ends is that it is considered that the portions corresponding to the back and the toes will not be bent. The groove portion 5 includes a slit portion 6 and two R portions 7 sandwiching the slit portion 6. The slit width F was 5 mm, the depth E was 41 mm, and the radius G of the R portion was 25 mm. In this case, the total width H of the groove 5 becomes 55 mm. To make the mat softer to bend and easily follow the deformation of the floor surface, it is preferable to increase the radius of the R portion. However, if it is too large, a part of the body enters into the groove portion, so that a feeling of strangeness is felt. From such a viewpoint, it is preferable that the radius G of the R portion be in the range of 18 to 27.5 mm. As a result of the above, the total width H of the groove 5 is preferably 41 to 60 mm.

[Effect of the invention]

 The present invention provides a mattress for a nursing care bed having a soft bend performance so as to easily follow a delicate bend of the floor surface while having a moderate compressive strength and a cushion performance, and a cushion material used for such a mattress. We were able to. Providing such a mattress also makes it easier for the cared person to take a posture that suits his or her body, such as when the cared person gets up, swells, or becomes tired. It was possible to make a comfortable life for the elderly. In addition, by providing mattresses that can easily take a comfortable posture that is suitable for the care recipient's body, the care recipient can replace their underwear etc. by themselves, and the care recipient can become independent. In addition to enabling caregivers to easily change their underwear, the burden on the caregiver was reduced, and both the cared person and the caregiver could live a comfortable life.
