Abstract
Description
- The present invention relates to comfortable and safe air mattresses.
- It is often the case that conventional air mattresses are provided in the form of an integral air mattress structured by the welding of front and back sheets thereof at each edge (see, for example,
Patent Documents 1 and 2).
Patent Document 1: Japanese Laid-Open Patent Publication No.7-308242 FIG. 2 )
Patent Document 2: Japanese Patent No.3290159 FIG. 5 ) - In the case of using the air mattress as described above to prevent bedsores, the internal pressure of the air mattress is regulated to be low to enhance body pressure dispersion performance. In such a case, if the internal pressure becomes excessively low, caving-in might occur.
- Also, in the cases of the edge structures as shown in
FIG. 2 ofPatent Document 1 andFIG. 5 ofPatent Document 2, when the air mattress is filled with air, its side surfaces are roundly inflated, and therefore a problem might occur where the buttocks slip off the air mattress easily when they are placed at the edge of the air mattress while attempting to rise therefrom. - Therefore, the present invention has been made to solve such a problem, and an objective thereof is to provide an integral air mattress capable of preventing caving-in, thereby allowing the buttocks to be stabilized at the edge of the air mattress.
- To achieve the above objective, the present invention provides an air mattress consisting of three sheets stacked and airtightly sealed at their circumferential portions, the mattress comprising: first-layer air cells consisting of tubular air cells formed widthwise by the first and second sheets; and second-layer air cells consisting of tubular air cells formed widthwise by the second and third sheets, the first-layer air cells and the second-layer air cells being arranged so as not to overlap in the longitudinal direction.
- Concretely, the overlying first-layer air cells are set at low pressure so as not to cause bedsores easily, while the underlying second-layer air cells are set at high pressure so as not to cause caving-in easily.
- Furthermore, side surface members are interposed and joined between their respective side edges of the top and bottom sheets, the side surface members each including two side surface sheets joined on their respective side edges such that the joined portion faces inward.
- In addition, the first-layer air cells are classified into two alternately arranged systems, such that the two systems are alternately inflated and deflated independently of each other, while the second-layer air cells are maintained at a predetermined internal pressure.
- The air mattress of the present invention has a dual layer structure in which the first-layer air cells and the second-layer air cells are arranged so as not to overlap in the longitudinal direction, and therefore it is possible to regulate the first-layer air cells and the second-layer cells independently of each other so as not to cause bedsores easily, while preventing caving-in.
- Concretely, the overlaying first-layer air cells hold the body of the user with low pressure, thereby making it possible topreventbedsores. Simultaneously,the underlyingsecond-layer air cells hold the body with higher pressure than the first-layer air cells, thereby making it possible to prevent caving-in.
- Furthermore, when the air mattress is filled with air, the side surface portions have rectangular cross sections, allowing the buttocks not to slip off easily when they are placed at the edge of the air mattress while attempting to rise therefrom.
- In addition, the first-layer air cells are classified into two alternately arranged systems, such that the two systems are alternately inflated and deflated independently of each other, thereby making it possible to cyclically change the position at which to support the body of the user to provide further bedsore prevention. In this case also, the second-layer air cells are regulated so as to be inflated with high pressure, thereby making it possible to inhibit caving-in.

FIG. 1 is a perspective view of an air mattress according to an embodiment of the present invention;FIG. 2 is a top view thereof;FIG. 3 is a schematic perspective view illustrating the bonding relationship of first through third sheets;FIG. 4 is a schematic cross-sectional view taken along line A-A inFIG. 2 ;FIG. 5 is a schematic cross-sectional view taken along line B-B inFIG. 2 ; and the same or similar elements in the drawings are denoted by the same characters. - The
air mattress 10 according to the present embodiment includes three flexible rectangular sheets, which are stacked together, from the top:first sheet 1,second sheet 2, andthird sheet 3, and bonded at circumferential portions 4. - The
first sheet 1 and thesecond sheet 2 are bonded at first bondingportions 5, thereby forming first-layer-system-A air cells 6a and first-layer-system-B air cells 6b. - In addition, the
second sheet 2 and thethird sheet 3 are bonded atsecond bonding portions 7, thereby forming second-layer air cells 8. - The three
sheets 1 through 3 are bonded at the circumferential portions 4. InFIG. 2 , thefirst bonding portions 5 at which to bond thefirst sheet 1 and thesecond sheet 2 are indicated by bold lines, and thesecond bonding portions 7 at which to bond thesecond sheet 2 and thethird sheet 3 are indicated by broken lines. The first andsecond bonding portions portions Patent Document 2. - Since the first and
second bonding portions tubular air cells FIG. 4 . As a result, the regulation as described below can be effectively carried out, and the surface of the air mattress that contacts the body during use is semioval, so that there is less surface irregularity compared to typical tubular air mats, enhancing reclining comfort. - In addition, the side surface portions are each formed by a side surface product 9 obtained by welding two
side surface sheets FIG. 5 , and a non-welding material, such as an insulator or suchlike (e.g., a polytetrafluoroethylene film), provided at non-welded side edges 9d of theside surface sheets portion 9c faces inwardbetween the side edge portions of thesecond sheet 2 and thethird sheet 3, and the side surface portion has a rectangular cross-section when filled with air. - Accordingly, when the
air mattress 10 is filled with air, the side surface portions have rectangular cross sections, allowing the buttocks not to slip off easily when they are placed at the edge of the air mattress while attempting to rise therefrom. Particularly, in the present embodiment, the hatched portion shown inFIG. 5 indicates the second-layer air cell 8 that has been subjected to the side surface processing as described above, and therefore is regulated so as tobe always inflated with high pressure, allowing further stable rising action. - During use, the first-layer-system-
A air cells 6a and the first-layer-system-B air cells 6b are regulated so as to be inflated with low pressure in order not to cause bedsores easily, and the second-layer air cells 8 are regulated so as to be inflated with high pressure in order not to cause caving-in easily. - As a result, portions of the
air mattress 10 that are in contact with the user are kept at low pressure so as to satisfactorily disperse body pressure. In addition, even if the first-layer air cells layer air cells layer air cells 8, making it possible to inhibit caving-in. - In another regulation method, thefirst-layer-system-
A air cells 6a and the first-layer-system-B air cells 6b are alternately inflated and deflated independently of each other, thereby making it possible to cyclically change the position at which to support the body of the user to provide further bedsore prevention. In this case also, the second-layer air cells 8 are regulated so as to be inflated with high pressure, thereby making it possible to inhibit caving-in.
