Description
WO 2008/046131 PCT/AU2007/001560 1 AIR MATTRESS Field of the Invention The present invention relates to a mattress. In particular, the present invention 5 relates to an air fillable mattress. Background of the Invention Many types of mattresses are known having various internal compositions and characteristics. The present market is moving away from traditional inner-spring 10 mattresses which are heavy to transport and are known to wear unevenly over time. Mattress trends in recent years have been towards construction from solid latex or solid viscoelastic foam. One disadvantage with latex and viscoelastic foam mattresses is that they do not readily permit different regions of the mattresses upper sleep layer to provide different firmness and support characteristics. Accordingly, when two people are 15 sharing a mattress, a compromise is required between their individual preferences of firmness and support. A further disadvantage with solid latex or viscoelastic foam mattresses is that they can provide excessive insulation which can be particularly problematic for people that generate large amounts of heat during sleep. The accumulation of heat during the 20 night may cause discomfort and reduce the quality of sleep experienced by a user. More recently air mattresses have been proposed. Existing air mattresses have a generally hollow mattress body defined by a base connected to four generally vertical side walls, defining a central cavity. One or more inflatable air bladders are typically located within the mattress cavity, and a padding and insulating layer is then placed over the air 25 bladder(s). The padded layer is then covered with a tufted sleep layer which is fastened to the periphery of the side walls of the mattress with a zipper. In the event that the user of the mattress desires a different mattress firmness or support level, the internal air pressure within the bladder can be selectively altered. In addition, different regions of the mattress sleep surface can be adjusted to different levels 30 firmness by providing multiple air bladders within the mattress cavity. A disadvantage of existing air mattresses is that the zipper seam is highly visible and it may be difficult to match the zipper colour with the colour of the mattress fabric. This can result in the unsightly zipper seam being easily observed in the assembled mattress. A further disadvantage of existing air mattresses is that the upper tufted sleep 35 layer generally stretches and/or warps as the mattress ages. This permits the sleep layer to WO 2008/046131 PCT/AU2007/001560 2 increase in area and the side walls may accordingly buckle outwardly. This may result in a deterioration of the quality and comfort provided by the upper sleep layer. The visual effect of the buckled side walls may also be unpleasant to some mattress users and the mattress may become unsuitable for use with fitted sheets and manchester. 5 A still further disadvantage of existing air mattresses is that the internal insulating layer is loose relative to the structural support components of the mattress, in order to provide access to the bladder when the sleep layer is removed. Accordingly, the insulating layer may move relative to the structural support components over time which can result in deterioration of the mattresses comfort and appearance. 10 Object of the Invention It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages, or at least to provide a useful alternative to existing air mattresses. 15 Summary of the Invention In a first aspect, the present invention provides an air mattress having an upper face forming a sleep surface, a lower face and a plurality of side faces each extending between said upper face and said lower face, said air mattress comprising: 20 a generally planar sleep panel defining said upper face; a peripheral skirt attached to said sleep panel around a perimeter of said sleep panel, said skirt defining said side faces; a frame located within said skirt, said frame including a plurality of frame elements, each frame element extending parallel and adjacent to one of said side faces, 25 said frame elements together defining a central cavity; a low-stretch base cover defining said lower face, said base cover being attached to said skirt around a perimeter of said base cover; one or more inflatable bladders located within said cavity; and a low-stretch intermediate panel located between said sleep panel and said 30 bladder(s), said intermediate panel being attached to said frame around a peripheral region of said intermediate panel. In the context of the present specification, the term "low-stretch" in relation to a cover, panel, layer or other element, means that the element only has a very limited ability to be stretched beyond its original dimensions when subjected to typical service loads and 35 envisages the use of materials known in the art as "non-stretch" materials.
WO 2008/046131 PCT/AU2007/001560 3 Typically, said intermediate panel is bonded to said frame. In a preferred embodiment, said intermediate panel comprises a compressible insulating layer and a low-stretch, non-tufted, woven or knitted fabric layer laminated to said compressible layer, said fabric layer being bonded to said frame around a peripheral 5 region of said fabric layer. The fabric layer of said intermediate panel may comprise yarns formed of one or more materials selected from the group consisting of cotton, polyester, polypropylene, viscose, cashmere, silk, bamboo, rayon and wool. The base cover is typically detachably attached to said skirt, in one form with a 10 zipper. Preferably, said base cover comprises a low-stretch, non-tufted, woven fabric layer. The skirt is typically bonded to said frame. Preferably, said sleep panel is tufted. 15 In one form, said sleep panel is fixed to said intermediate panel around a peripheral region of said sleep panel. The sleep panel may comprise multiple laminated layers. The air mattress may further comprise one or more cushioning layers located between said intermediate panel and said sleep panel. 20 The air mattress may have two said bladders arranged in parallel side by side relation in said cavity. A rail member may be located in said cavity between said bladders. Typically, said side faces, said upper face and said lower face define a rectangular prism. 25 In a second aspect, the present invention provides an air mattress having an upper face forming a sleep surface, a lower face and a plurality of side faces each extending between said upper face and said lower face, said air mattress comprising: a generally planar sleep panel defining said upper face; a peripheral skirt fixedly attached to said sleep panel around a perimeter of said sleep 30 panel, said skirt defining said side faces; a frame located within said skirt, said frame including a plurality of frame elements, each frame element extending parallel and adjacent to one of said side faces, said frame elements together defining a central cavity; a base cover defining said lower face, said base cover being detachably attached 35 to said skirt around a perimeter of said base cover; inece.veu 14 iviay zuu 4 one or more inflatable bladders located within said cavity; and an intermediate panel, comprising an insulating compressible layer, located between said sleep panel and said bladder(s), said intermediate panel extending across said cavity. 5 The intermediate panel is typically attached to said frame around a peripheral region of said intermediate panel. Typically, said base cover is detachably attached to said skirt with a zipper. The zipper is preferably located on said lower face. The skirt may comprise a primary skirt portion defining said side faces and a flap io depending from a lower edge of said primary skirt portion and extending at least partly across a lower face of said frame. Preferably, said primary skirt portion and said flap are each bonded to said frame. Preferably, said zipper is fixed to said flap. 15 Brief Description of the Drawings Preferred embodiments of the present invention will now be described, by way of example only with reference to the accompanying drawings in which: Fig. 1 is an exploded perspective assembly view of an air mattress; 20 Fig. 2 is a fragmentary, cross-sectional end elevation view of the air mattress of Fig. 1; Fig. 3 is a perspective view of the frame and intermediate panel of the air mattress of Fig. 1; Fig. 4 is an inverted perspective view of the frame and intermediate panel of Fig. 25 3; Fig. 5 is an inverted exploded perspective assembly view of the frame, intermediate panel and skirt of the air mattress of Fig. 1; Fig. 6 is an inverted perspective view of the frame, intermediate panel and skirt of Fig. 5 when assembled; 30 Fig. 7 is an exploded perspective view of a portion of the skirt of the air mattress of Fig. 1.; Fig. 8 is an inverted exploded perspective assembly view of the frame, intermediate panel, bladders, centre rail and base panel of the air mattress of Fig. 1; Fig. 9 is a perspective view of the centre rail of the air mattress of Fig. 1; Amended Sheet

The air mattress 10 includes an upper face 11 forming a sleep is surface, a lower face 12, opposing lateral side faces 13, 14 and opposing end side faces 15, 16. The side faces 13, 14, 15, 16 each extend between the upper face 11 and the lower face 12. The upper and lower faces 11, 12 and side faces 13, 14, 15, 16 together define a rectangular prism, although other shapes are envisaged to suit specific bedding configuration requirements. 20 The air mattress 10 includes a generally planar sleep panel 20 which defines the upper face 11. A peripheral skirt 30 is attached to the sleep panel 20 around a perimeter of the sleep panel 20 and defines the side faces 13, 14, 15, 16. An internal frame 40 is located within the skirt 30. The frame 40 includes four frame elements in the form of elongate foam beams 41. Each foam beam 41 extends parallel and adjacent to one of the 25 side faces 13, 14, 15, 16 and the foam beams 41 together define a rectangular enclosure having a central cavity 42. Depending upon the specific geometric configuration of the air mattress, varying numbers of foam beams may be utilised as required to form the desired shape, which will also be reflected in the shape of the central cavity 42. A base cover 50 defines the lower face 12 and is attached to the skirt 30 around a perimeter of the 30 base cover 50. Two inflatable bladders 60 are located in the cavity 42 in a side-by-side relation, providing separate sleep regions for two people sleeping side-by-side on the air mattress 10 when configured as, for example, a double, queen or king sized mattress. For single bed configurations, a single bladder 60 only would typically be provided. Each bladder 35 60 is separately fillable with air through an air valve 61 connected to an air compressor or WO 2008/046131 PCT/AU2007/001560 6 pump (not shown). Accordingly, the air pressure within each bladder 60 can be set to a different level which permits a different firmness to be set in the two sleep regions of the mattress 10 associated with the two bladders 60. Each bladder 60 may include internal reinforcing walls or stiffening ribs as desired. The two bladders 60 will typically be 5 separated by a centre rail 62 loosely located within the cavity 42. Filling of the bladder 60 is typically controlled by a control unit (not shown) which may be fitted to bed furniture, (such as the bed frame) by way of a remote control unit operating on infra-red radio-frequency or other signal transmission system. The control system communicates with the valve and the pump or compressor. In 10 configurations utilising more than one bladder 60, each bladder 60 may be controlled by a separate control unit, and a receiver control unit may be provided having settings for multiple bladders 60. An intermediate panel 70 is located between the sleep panel 20 and the bladders 60 and extends across the cavity 42. A base panel 80 may also be provided between the is bladders 60 and the base cover 50. Construction of the air mattress 10 and specific features of each of the elements of the air mattress will now be described with reference to Figures 3 to 13. Figures 3 and 4 depict the intermediate panel 70 and frame 40, which are typically constructed and joined during the first stage of construction of the air mattress 20 10. To improve the structural rigidity of the air mattress 10, and to avoid displacement of the intermediate panel 70, the intermediate panel 70 is attached to the frame 40 around a peripheral region of the intermediate panel 70, adjacent the perimeter of the intermediate panel 70. The intermediate panel 70 is also low-stretch, such that it has only a very limited ability to be stretched beyond its original dimensions when subjected to typical 25 service loads, thereby assisting in retaining the structural shape of the frame 40. The term "low-stretch" also includes the use of materials described in the textile industry as "non stretch" which would inherently exhibit some, albeit perhaps negligible, stretch under typical service conditions. In the arrangement depicted, the intermediate panel 70 is a laminated structure 30 comprising a compressible insulating layer 71 and a low-stretch non-tufted, woven fabric layer 72. The compressible insulating layer 71 is laminated to the woven fabric layer 72 by bonding with a suitable adhesive. The compressible insulating layer 71 may be in the form of a polyurethane foam, latex, open woven fabric, or other such insulating compressible material which will typically be relatively stretchable in isolation. In the 35 arrangement depicted, the compressible insulating layer 71 is formed of a 24 mm thick WO 2008/046131 PCT/AU2007/001560 7 polyurethane foam. The compressible insulating layer provides both cushioning and insulating properties to the mattress 10. The compressible insulating layer 71 dissipates heat away from the user's body, and keeps the user insulated relative to the air within the bladders 60. Noise insulation is also provided to reduce transmission of noise, caused by 5 filling/discharge of the bladders 60 and by either bladder 60 rubbing against the frame 40 and central rail 62. The woven fabric layer 72 may comprise woven yarns formed from one or more of any of various low-stretch materials, including cotton, polyester, polypropylene, viscose, cashmere, silk, bamboo, rayon, wool or the like. In the particular arrangement 10 depicted, the woven fabric layer 72 is made from a blended yarn comprising 51.9% cotton, 27.6% polyester and 20.5% polypropylene with a weight of 200.6 gsm (g/m 2 ) The fabric layer 72 might alternatively be knitted rather than woven. The woven fabric layer 72 provides structural rigidity to the mattress 10, retaining the structural shape of the frame 40. 15 The woven fabric layer 72 is slightly broader and longer than the compressible insulating layer 71, such that an edge region 73 of the woven fabric layer 72 overhangs the perimeter of the compressible insulating layer 71. The foam beams 41 are typically formed of high density polystyrene foam, which may suitably have a density of the order of 31 kg/m 3 . The frame 40 is formed in 20 situ on the intermediate panel 70 in an inverted position, specifically on the exposed face of the woven fabric layer 72, by positioning each of the foam beams 41 of the frame 40 adjacent an edge of the intermediate panel 70, with the overhanging edge region 73 of the woven fabric layer 72 projecting beyond the outer face 43 of each foam beam 41. Each foam beam 41 is attached to the intermediate panel 70, typically by adhesively bonding 25 each foam beam 41 to the exposed face of the woven fabric layer 72. The foam beams 41 may alternatively be attached to the intermediate panel by stitching, welding or any other such permanent attachment. The edge region 73 of the woven fabric layer 72 is then folded over the outer face 43 of each foam beam 41 and adhesively bonded thereto. The frame 40 and intennediate panel 70 when assembled together define a structural mattress 30 box. Figure 5 depicts the assembled frame 40 and intermediate panel 70 in the inverted position, with the skirt 30 ready to be located about the frame 40 and fixed thereto, as depicted in Figure 6. The skirt 30 extends about the outer face 43 of each of the foam beams 41 of the frame 40 so as to locate the frame 40 within the skirt 30. In the 35 arrangement depicted, the skirt 30 comprises a primary skirt portion 31, and a flap 32 that WO 2008/046131 PCT/AU2007/001560 8 depends from the lower edge of the primary skirt portion 31 (appearing as the upper edge in Figures 5 and 6 where the assembly is inverted). As can be best seen in Figure 6, the flap 32 is folded over so as to extend across the lower face 44 of each of the foam beams 41. The primary skirt portion 31 and flap 32 are each adhesively bonded to the frame 40, 5 further reinforcing the mattress 10 and fixing the relative location of each foam beam 41. Referring to Figure 7, the skirt 30 may be formed as a laminated structure, typically comprising a fibrous quilt backing layer 31, middle foam layer 34 and outer tick layer 35. The tick layer 35 would typically be comprised of a polyester and spun rayon blend fabric. The layers forming the skirt 30 are stitched together in a quilted or tufted 10 configuration. Referring to Figure 8, the bladders 60 are then located in the cavity 42 with the partially assembled mattress still in the inverted condition. The centre rail 62 is loosely located between the bladders 60. As depicted in Figure 9, the centre rail 62 is typically provided with castellated or undulating upper and lower faces 63, 64 so as to increase the is compliance of the centre rail 62 when subject to vertical loads, so as not to cause discomfort to a user lying in the centre of the air mattress, while still performing its function of separating the individual bladders 60. The centre rail 62 is typically formed of a high density polystyrene foam. Referring back to Figure 8, the base panel 80 is then located to extend across the 20 cavity 42. The base panel 80 would typically be located loosely within the bounds of the cavity 42, without being fixed to the frame 40 or any other elements of the air mattress 10, so as to provide for ready access to the bladders 60 when the air mattress 10 is in the inverted condition with the base cover 50 removed. The base panel 80 is typically formed of a compressible foam, for example, a 25 polyurethane or polyester foam, with a thickness of the order of 25 mn so as to isolate the bladders 60 from the mattress foundation (such as a bed frame or ensemble base) on which the air mattress 10 would typically be located in use, thereby protecting the bladders 60 from any otherwise potentially damaging projections or the like in the foundation. 30 Referring next to Figure 10, the base cover 50 is attached to the skirt 30 around a perimeter of the base cover 50. So as to provide access to the bladders 60, the base cover 60 is detachably attached to the skirt 30, typically by way of a zipper 51. Alternatively a Velcro TM seam, buttons, a number of hooks and corresponding loops or another such suitable fastening system may be utilised. To best hide the zipper 51, when the air 35 mattress is in the upright position, the zipper 51 is located on the lower face 12.
WO 2008/046131 PCT/AU2007/001560 9 Specifically, one side of the zipper 51 is sewn to the perimeter of the base cover 50, whilst the opposing side of the zipper 51 is sewn to the flap 32 of the skirt 30. As best depicted in Figure 2, an edging tape 36 is used to sew the zipper 51 to the flap 32 and to neatly finish the intersection between the lower face 12 and side faces 13, 14, 15 and 16. 5 The edging tape 36 also further hides the zipper 51 from view when the air mattress 10 is in the upright position. The base cover 50 is typically formed of the same fabric as the woven fabric layer 72 of the intermediate panel 70, so as to provide further structural rigidity to the structure of the air mattress 10, as compared for example, to a tufted or quilted fabric. As for the woven fabric layer 72 of the intermediate panel 70, however, 10 any suitable low-stretch material may be utilised for the base cover 50. The base cover 50 may be fitted with straps, hooks or other such fasteners (not shown) in order to integrate the air mattress 10 with a strapping system for raising a portion of the air mattress 10 relative to a horizontal plane, for example to provide distinct sitting and laying modes of air mattress 10 inclination. 15 The partly assembled mattress is then turned over into the upright position and, as depicted in Figure 11, the sleep panel 20 is positioned over the intermediate panel 70 and underlying frame 40. The sleep panel 20 is designed to provide an aesthetically pleasing appearance and to provide a comfortable sleep surface. The sleep panel 20 will typically be a 20 laminated structure, an example of which is depicted in Figure 12. Here the sleep panel 20 comprises an outer tick layer 21, a fibre fill layer 22, a foam layer 23, and a fibrous quilt backing layer 24. These layers are stitched together in a quilted or tufted configuration. The tick layer 21 is typically tufted and may comprise, for example, polyester, cotton and/or polypropylene fabric. The fibre fill layer 22 will typically 25 comprise polyester and/or wool. Referring to Figure 13, the sleep panel 20 is fixed to the intermediate panel 70 around a peripheral region of the sleep panel 20, here by adhesive bonding. The central region of the sleep panel 20 is, however, not fixed to the intermediate panel 70, allowing relative movement therebetween as the top panel 20 is defonned by a user's movements 30 with the intermediate panel 70 remaining fixed to the frame 40. The sleep panel 20 is then directly fixed to the skirt 30 by sewing a further edging tape 37 to the perimeter of the sleep panel 20 and the upper edge of the skirt 30, as best depicted in Figure 2. This completes the construction of the air mattress 10. The fully assembled air mattress 10 has a substantially identical appearance to 35 other common forms of mattress, with only the sleep panel 20 and skirt 30 being readily WO 2008/046131 PCT/AU2007/001560 10 visible by locating the zipper 51 (or other detachable attachment means) between the skirt 30 and base cover 50. The low-stretch characteristics of both the intermediate panel 70 and base cover 50, which are each attached to the frame and/or skirt, also provide for improved structural rigidity of the air mattress, with the low-stretch intermediate panel 70 5 particularly inhibiting deformation of the frame 40 as a result of stretching or warping of the sleep panel 20. The intermediate panel 70 also inhibits sinking of the sleep panel 20 into the cavity 42 when either bladder 60 is set at a low pressure which would otherwise deform the sleep surface of the air mattress 10. In scenarios where the visibility of the zipper 51, or access to the cavity 42, is not 10 of concern, it is envisaged that the sleep panel 20 and intermediate layer 70 may be secured to the frame 40 and/or skirt 30 by way of zippers, thereby providing access to the bladders 60 when the air mattress 10 is in the upright position. Further, where structural rigidity of the air mattress 10 and displacement of the intermediate layer 70 is not of such concern, it is envisaged that the low-stretch non 15 woven fabric layer 72 of the intermediate panel 70 might be omitted, potentially with the compressible insulating layer 71 merely extending across the cavity 42 without being attached to the frame 40. It is also envisaged that alternate versions of the air mattress 10 may be provided with pillowtop configurations and the like, for users desiring additional 20 comfort/cushioning layers. Such an alternate air mattress 10' is depicted in the fragmentary, cross-sectional view in Figure 14. The structure of the air mattress 10' and method of construction, is essentially identical to that of the air mattress 10 described above, apart from the addition of additional cushioning layers 90, 91 located between the intermediate panel 70 and top panel 20. To accommodate for the extra thickness of these 25 cushioning layers 90, 91, the skirt 30 is provided with a gusset portion 38 extending about an upper edge of the primary skirt portion 31. The gusset portion 38 is stitched to the primary skirt portion using a further edging tape 39. The cushioning layers 90, 91 will typically be laminated to the intermediate panel 70 by adhesive bonding. The sleep panel 20 is then adhesively bonded to the upper cushioning layer 90 around the peripheral 30 region of the sleep panel 20. In the arrangement depicted, the upper cushioning layer 90 is a 50 mm thick viscoelastic foam layer, whilst the lower cushioning layer 91 is a 25 mm thick latex layer. Other types of cushioning layers as are known in the art, such as foam layers with a convoluted face may also be used. Such convoluted foam layers may be formed, for example, from polyurethane or polyester foam.
WO 2008/046131 PCT/AU2007/001560 11 Although the invention has been described with reference to two specific embodiments, it will be appreciated by those skilled in the art that the invention may be embodied in many other forms.
