Definitions

  • the present invention relates to comfortable and safe air mattresses.
  • Patent Document 1 Japanese Laid-Open Patent Publication No. 7-308242 ( FIG. 2 )
  • Patent Document 2 Japanese Patent No. 3290159 ( FIG. 5 )
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the overlaying first-layer air cells hold the body of the user with low pressure, thereby making it possible topreventbedsores.
  • 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.
  • 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.
  • 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.
  • 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 in FIG. 2
  • FIG. 5 is a schematic cross-sectional view taken along line B-B in FIG. 2 ; and the same or similar elements in the drawings are denoted by the same characters.
  • the air mattress 10 includes three flexible rectangular sheets, which are stacked together, from the top: first sheet 1, second sheet 2, and third sheet 3, and bonded at circumferential portions 4.
  • first sheet 1 and the second sheet 2 are bonded at first bonding portions 5, thereby forming first-layer-system-A air cells 6a and first-layer-system-B air cells 6b.
  • second sheet 2 and the third sheet 3 are bonded at second bonding portions 7, thereby forming second-layer air cells 8.
  • the three sheets 1 through 3 are bonded at the circumferential portions 4.
  • the first bonding portions 5 at which to bond the first sheet 1 and the second sheet 2 are indicated by bold lines
  • the second bonding portions 7 at which to bond the second sheet 2 and the third sheet 3 are indicated by broken lines.
  • the first and second bonding portions 5 and 7 are each arranged so as not to overlap in the longitudinal direction.
  • sloping arced portions between right and left air cell portions cause the bonding portions 5 and 7 not to overlap in the front-rear direction, as in Patent Document 2.
  • the tubular air cells 6a, 6b, and 8 are formed with cross-sections not representing perfect circle segments but oval segments as shown in FIG. 4 .
  • 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.
  • the side surface portions are each formed by a side surface product 9 obtained by welding two side surface sheets 9a and 9b once only on their respective side edges 9c as shown in 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 the side surface sheets 9a and 9b, the side surface product being disposed such that the welded portion 9c faces inwardbetween the side edge portions of the second sheet 2 and the third sheet 3, and the side surface portion has a rectangular cross-section when filled with air.
  • a non-welding material such as an insulator or suchlike (e.g., a polytetrafluoroethylene film)
  • 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.
  • the hatched portion shown in FIG. 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.
  • 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.
  • 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.
  • the first-layer air cells 6a and 6b at lowpressure are heavilydepressed by rolling over in sleep, the first-layer air cells 6a and 6b are supported with high pressure by the underlying second-layer air cells 8, making it possible to inhibit caving-in.
  • 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.
  • the second-layer air cells 8 are regulated so as to be inflated with high pressure, thereby making it possible to inhibit caving-in.
