Definitions

  • the present invention relates generally to the field of inflatable support systems, which may include air mattresses and inflation controls thereof. More specifically, the present invention relates to an inflatable two-chamber air mattress with a raised inflatable headboard chamber.
  • the Chaffee patent teaches the use of a large, manually operated pressure release valve to speed deflation.
  • the Chaffee patent also teaches the inclusion of a small cylinder around which a deflated bed can be rolled, further simplifying deflation. This same arrangement also allows the bed to automatically unroll while being inflated, which also simplifies the inflation process.
  • the Chaffee patent also illustrates the inclusion of an electric motor and pump, which speed the inflation process.
  • the Hsu patent attempts to address some of the comfort problems typically associated with air mattresses.
  • the Hsu patent utilizes tube beams inside a mattress to provide additional lateral load support. These tube beams are structures that are added to the inside of the mattress and are attached to the upper and lower mattress surfaces through a sinusoidal sealing pattern in an attempt to provide further rigidity to the mattress.
  • a person sleeping on mattresses such as those described in the Chaffee and Hsu patents still may have the perception of sleeping on the floor. Furthermore, getting into and out of such a bed can be difficult, especially for an elderly or disabled person.
  • a solution to this problem is to provide a mattress that approximates the dimensions of a traditional bed, such as height and width. But, such inflatable mattresses have a propensity to roll over. Rollovers are not only a problem with inflatable mattresses, but with all lightweight support surfaces, such as inflatable furniture.
  • Some in the prior art such as U.S. Patent No. 6,161,902, issued to Marvin S. Lieberman on December 19, 2000 (the Lieberman patent) and the ''Retro Air Chair" by Intex Recreation Corporation of Long Beach, CA, have used multiple inflatable cylindrical tubes to improve the stability of inflatable chairs.
  • the stabilization methods employed in the prior art can improve overall chair stability, each has shortcomings, especially when applied to other support systems.
  • the Lieberman patent teaches the installation of a "U" shaped inflatable tube underneath the front of a chair and a small inflatable tube extending along and immovably attached to the rear base of the chair.
  • Each of these tubes is also inflated separately from and to a higher pressure than the body of the chair. The increased pressure of these tubes strengthens the base of the chair, thus reducing the likelihood of rollover. While this approach has some merit, the introduction of separately inflatable tubes means added work for the consumer, who must move an inflation device from one valve to another until the chair is properly filled.
  • the Retro Air Chair applies an alternative stabilization technique.
  • Two small inflatable stabilizer bars are attached to the base of the chair to increase the surface area covered by the chair. These stabilizer bars are attached to the chair through narrow, short inflator tubes.
  • the inflator tubes allow the stabilizer bars to be in fluid communication with the chair body and to fill with air as the chair is filled.
  • the increased surface area created by the combination of the inflator tubes and the stabilizer bars provides more stability by distributing the weight over a larger area.
  • the shape and position of the stabilizer bars employed on this chair also strengthens the chair body where the stabilizer bars contact the chair.
  • such strengthening is only provided to areas adjacent to the tubes. While this may be practical for inflatable support systems with smaller weight bearing surfaces, such as chairs, a few, relatively short stabilizer bars will not provide stability for larger inflatable support systems, such as inflatable mattresses.
  • An additional problem faced by inflatable support systems of the prior art is structural stability of the sides of the support system.
  • the shape of the sides tends to distort as weight is applied at or near the edge of the support system. Such distortion can cause instability in the top surface of the mattress near the edges. This problem becomes increasingly significant as the height of the support system is increased.
  • a means of improving the structural stability of the side of the mattress is therefore preferable as height is increased.
  • an inflatable support system that has all of the comforts and amenities of a traditional mattress and frame or boxspring structure. Therefore, means of improving the comfort and end user familiarity with the support structure is preferable.
  • One such inflatable support structure may include features that allow the end user to apply traditional mattress covering materials to the inflatable raised structure while providing the end user with a familiar headboard design.

It should be clear to one skilled in the art that alternative support chamber constructions and optional side gusset heights and chamber arrangements could be substituted without departing from the spirit and scope of the present invention.
  • the upper suppo ⁇ chamber 20 may rest on iop of the iower support chamber 21 .
  • the top layer 38 of the low-er support chamber 21 may be in contact with the bottom layer 36 of the upper support chamber 20.
  • FIG. 3 illustrates, a motorized pump 10 is attached to upper support chamber 20.
  • the pump 10 should be powerful enough to fill the entire support system with a gas or fluid, such as air, such that the upper support chamber 20 can provide comfortable support to a user. Inflation of the support system can begin by pressing a button 23 on or near the pump 10, as is illustrated in Figure 3.
  • the pump 10 may automatically stop inflating the support system when the pressure within the support system reaches a limit selectable by a user.
  • a user simply activates a dump valve 27.
  • the pump 10 may also monitor support system air pressure and automatically add additional air if the pressure falls below a level selected by a user.
  • Air entering the upper support chamber 20 may flow into the lower support chamber 21 through a series of reinforced openings, as shown in Figure 1. These openings 1 1 arc defined in the top layer 38 of the lower support chamber 21 and the bottom layer 36 of the upper support chamber 20. The openings 1 1 are substantially aligned such that air may How between them.
  • a reinforcing chamber 14 is included in the support system.
  • This reinforcing chamber 14 runs circumferentially around the support system at the junction between the upper support chamber 20 and the lower support chamber 21 .
  • the reinforcing chamber 14 may run around the entire circumference of the upper and lower support chambers 20 and 21 , or may be disposed only around the sides and proximal end of the chambers, in a U-shape.
  • the reinforcing chamber 14 may be attached to the side gussets 32, 42 of the upper 20 and lower 21 inflatable support chambers, respectively.
  • the reinforcing chamber 14 may be attached to the mattress by the side gusset 42 and top layer 38 of the lower reinforcing chamber 21 , or, optionally, no reinforcing chamber may be used at all.
  • the upper support chamber 20, lower support chamber 21, inflatable headboard chamber 60 (described below), and reinforcing chamber 14 are preferably made from heavy weight (preferably 18 gauge) polyvinylchloride (PVC) or other watertight and airtight material.
  • PVC polyvinylchloride
  • PVC may be attached to PVC or other material by electronically “welding" the PVC to the other material, although other attachment means, such as through a chemical bond or by stitching edges of each sheet together, may also be used.
  • Such an attachment means may be used, for example, to join the top of a chamber with the side of a chamber or to add a layer of fabric, padding, flocking, or other material (collectively "fabric") to the PVC.
  • Figure 3 is a front planar view of a mattress embodiment.
  • PVC strips 15 can be attached to the inner surface of the top layer 34, 38 and bottom layer 36, 40 of each chamber 20, 21 .

  • the embodiment shown uses four such openings 1 1 , each of which is approximately three quarters of an inch in diameter. Each opening 1 1 is substantially centered within a circular weld four inches in diameter, where such a weld can also serve to attach the upper support chamber 20 to the lower support chamber 21. It should be obvious to one skilled in the art that other opening arrangements, including, but not limited to, fewer openings of a larger size, or more openings of a smaller size, may also be used.
  • the reinforcing chamber 14 may be in fluid communication with the lower support chamber 21 through any number of openings 16 and runs circumfcrcntially around the support system, desirably in a U-shapc. As described below, the distal ends of the reinforcing chamber 14 and the lower inflatable support chamber 21 may be directly attached to a front gusset of the inflatable headboard chamber, negating the necessity that the reinforcing chamber extend the entire perimeter of the upper and lower inflatable chambers. In an alternative embodiment, the reinforcing chamber 14 may receive air from the upper support chamber 20. In still another embodiment, the reinforcing chamber 14 may be in fluid communication with both the upper support chamber 20 and the lower support chamber 21.
