Definitions

  • the present invention relates to air beds generally, and more particularly, to an improved air bed system with independently inflatable sections for providing varying degrees of support over a sleeper's body.
  • Air beds having independently inflatable mattresses for separate sleepers are known, but they could be improved.
  • currently available air mattresses may "bottom out” when the weight thereon is too high, resulting in an uncomfortable mattress.
  • Single mattresses or pairs of independently inflatable mattresses connected together for separate steepers may also create a rolling effect when one person lays down on the bed, resulting in the other person being jostled.
  • the support for the sleeper's body in many conventional air mattresses is not always satisfactory.
  • additional support is needed in the lumbar region.
  • increasing the inflation pressure to provide the needed lumbar support results in a mattress which is then uncomfortable for the sleepers head and leg positions. Failure to provide adequate lumbar support may result in the sleeper sinking into a "valley" as the mattress compress in the lumbar region and expand under the sleeper's head and feet due to the reduced weight distribution in those areas.
  • an air bed system of the present invention comprises three separate airtight segments secured together in a linear fashion to form an air mattress sized to fit a standard twin-sized bed.
  • Each segment of the air mattress is independently inflatable, allowing sleeper to adjust the level of support provided by alternativeng the air pressure within each segment.
  • a full, queen, or king sized bed may be formed for two separate sleepers by placing two air mattresses of the present invention side by side, allowing each sleeper to retaining individual support level and comfort adjustments.
  • a standard air mattress 10 is shown formed from a single air-tight bladder 12. Support is provided by air introduced into the air-tight bladder 12 through a suitable valve 14, preferably a double valve with a reverse flow inhibitor. It is well known in the art that these valves (sometimes known as Boston valves) simplify the inflation of air mattresses and avoid undesired releases of air from the air-tight bladder 12.
  • the air mattress 10 additionally has a plurality of internal partitions 16 extending across its width. The partitions 16 are internally secured to both the top 18 and bottom 20 surfaces of the bladder 12 by means of continuous seams 22. The partitions 16 define a plurality of interconnected chambers 24 therebetween and their structure substantially strengthens the air mattress 10, increasing support after inflation.
  • a second air-mattress substantially identical in size is positioned adjacent the first mattress 10.
  • each segment forms an individual air-tight compartment.
  • a suitable valve 34, 36, and 38 of the type describe above for adjusting the internal air-pressure is incorporated within each segment.
  • An additional layer of a quilting material may be provided to cover the upper surface of the lumber segment 30.
  • Each segment contains several double-walled internal partitions 40 (Fig. 3) which extend across the segment width, creating interconnected chambers 42 and providing additional support upon inflation.
  • each partition 40 is hollow, with openings 44 at the ends and openings 46 in the middle which allow air to flow from chamber to chamber as weight is applied to the segment.
  • Each partition 40 is preferably welded at its top 48 and its bottom 50 to the corresponding top and bottom surfaces of the segment (28, 30, or 32 as applicable). This welded seam runs horizontally and is preferably about 1 ⁇ 2" in width for each partition 40.
  • This partition design provides greater seam surface area and two partition walls (52 and 54) for added air containment and strength.
  • the number of partitions 40 per segment varies depending upon the desired size and strength of the air mattress 26.
  • an assembled air mattress 26 is formed by securing the head segment 28 to the adjacent side of the lumbar segment 30, and the foot segment 32 to the adjacent side of the lumbar segment 30, opposite the head segment 28.
  • the preferred method for securing the individual segments together is by means of matching hook and loop fastener strips 56a, 56b, such as those sold under the trade name Velcro, arrayed along the adjacent upper edges 57 and lower edges 58 of each of the segments as seen in Figs. 2 and 2a.
  • the air mattress 26 is preferably placed on a foundation 60 (Fig. 5) consisting of form perimeter rails 62 covered in a textured vinyl material.
  • the valves 34, 36, and 38 are then connected to two or more pneumatic pumps 64, 66, housed within the foundation 60 to keep operational noise levels to a minimum.
  • Separate controls 68 operate the pneumatic pumps 64, 66, permitting an individual using the air mattress 26 to separately inflate or deflate the head segment 28, the lumbar segment 30, and/or the foot segment 32, or to simultaneously adjust both the head and foot segments separate from the lumbar segment.
  • a second air mattress is employed (Fig. 6).
  • the second mattress is a mirror image of the first, having a second set of identical pneumatic pumps and separate controls placed within the foundation 60.
  • an individual sleeper may adjust the second portion of the air bed system to his or her individual comfort levels without affecting the comfort of a first sleeper on the first air mattress.
