Abstract
ABSTRACT
An inflatable bed system which is an alternative to wedges, pillows, props and adjustable hospital beds is disclosed. The invention allows for multi-level reclining adjustment, and independently raises or lowers neck, shoulders, back or legs for comfort, the levels of adjustment being controlled by the user of the bed via a lightweight hand-held control. The inflatable bed system is capable of being used in conjunction with bed frames built to accommodate non-adjustable mattresses and foundations. A platform is provided, and support means are positioned above the platform. Inflatable bags are positioned between the platform and the support means. The support means may be hinged panels which support a flexible mattress or mattresses, or the support means may be a semi-rigid structure such as an inflated air mattress, obviating the need for a separate mattress. Controls permit individual sections to be raised or lowered by inflating or deflating selected air bags.

Description
-~ 2013~0 INFLATA~LE ~D SY5TEM
This invention relates generally to an inflatable bed system, and specifically to one which permits a person to selectively elevate or lower the head and foot sections of the bed.
The most common adjustable bed systems in the prior art are beds which through a crank or related systems, are adjusted to make the user more comfortable.
The adjustable beds used in hospitals and other institutions are generally either electrically or manually operated. The frame of these products is usually made of heavy metal and the base of the bed actually bends up and down, to facilitate the adjustable feature. An adjustable mattress is placed on top of the frame without any type of box spring. The adjustable beds of the prior art generally are of a height off the floor significantly greater ~han that of non-adjustable beds, making these beds too high off the ground for some persons to use unassisted.
It is an object of the invention to provide an inflatable bed which avoids some of the problems associated with prior art bed systems, and in particular to provide an adjustable bed system which performs well but which may cost considerably less ~han conventional adjustable bed systems.
The invention offers an alternative to foams, wedges, pillows, props and adjustable hospital beds. The invention allows for multi-level reclining adjustment, and independently raises or lowers upper and lower sections for com~ort, the levels of adjustment being controlled by the user of the bed via a simple hand-held control. The invention is capable of being used in conjunction with bed frames built to accommodate non-adjustable mattresses and foundations. The invention '~'";.,... ,, , , :

"'''~",, ' ~ :
20~ 3~0 enables existing non-adjustable beds to be replaced by an adjustable system with a simple change of the mattress and foundatio~, yielding an adjustable bed of relatively light total weight, thereby facilitating movement and enhancing portability (e.g. for cleaning or interior design purposes), for a price which should be significantly less than that of adjustable beds in the prior art. Consumers should be able to purchase this new bed system for a price which is only marginally higher than a standard mattress and foundation.
The invention involves a generally horizontal platform, and support means including at least one section hinged to the platform. At least one inflatable bag is positioned between the platform and the support lS means. Air distribution means connect to each of the inflatable bags, the air distribution means including pump and valve means for inflating or deflating the inflata~le bags. Control means control whether tne air distribution means is inflating or deflating.
Preferably, there are at least two hinged sections, namely one for the head end of the bed and one ~
for the foot end, each ection having a separate ~ ~-inflatable bag. In a preferred embodiment for two persons, there are four hinged ~ections, namely head and fo~t for each person (left and right), each with an inflatable bag. The control means and air distribution system can selectively inflate or deflate any selected inflatable bag.
In order that the invention may be more clearly understood, the preferred embodiment thereof will now be described in detail by way of example, with reference tQ
the accompanying drawings, in which:

Referring to Figs. 1 and 2, the preferred embodiment has a substantially horizontal platform 1, similar in size and appearance to a hox spring unit but essentially rigid, and mattress support means such as hinged panels 2 positioned above the platform. In the preferred e~bodiment, a flexible mattress or mattresses 4 is~ar~ positioned on top of the support means.
Inflatable bags 6 of plastic or the like are positioned between the pIatform and sections of the panels, such that inflation o~ the bags pushes the panel sections upwardly, and deflation allows them to return to the horizontal position on top of the pla~form. ~n air distribution unit 8 iS connected to connections 10 on the inflatable bags by air distribution means such as lengths of 20 mm diameter PVC tubing 12.

unit 8 is preferably housed in the interior compar~ment 14 of the platform 1.
The upper surface of the platform 1 is preferably of melamine coated particle board or the like.
For aesthetic reasons, the side walls 16 of the platform are preferably covered with a quilted material or the~ ~
like, as in conventional mattress and box spring sets. -The upper surface of the platform prefera~ly is slightly recessed below the top of the side walls to accommodate 10 the thiokness of the hinged panelsl so that they do not~-~
project above the top of the side walls. ~-The inflatable bags 6 may be independently inflated so as to raise any one, combination of, or all-~
o~ the left and rig~ side~ of the an~erior and posterior ends ("head" and "foot" sections) of the hinged panels 2, which in turn elevates the equivalent ends of mattress sections 4 removably placed onto the panels. The inflatable bags 6 are secured independently to the top face of the platform via fastening means such as the nuts and bolts 18 which clamp an extension of the bag between the upper surface of the platform and the fixed center panel 20.
As mentioned above, the support panels 2 for each side of the bed (i.e. left and right) preferably are made of melamine coated particle boar~ (5/8" thick) or the like. T~ey include a center panel 20 which is bolted to the upper surface of the platform, an upper or "head"
panel 22, and two lower or "foot" panels 24. The two lower panels are hinged such that they bend approximately at the average person's knee location. The panels are connected to each other by hinges 26, preferably "piano"
~inges extending across most of the width of the panel.
As can be readily apprsciated from an examination of Fig. 1, mattresses of a variety of sizes may readily be used in con~unction with the invention.

~` 20~ 3~
Two inflatable bags of appropriate dimensions would be used in conjunction with either 1:win or single sized mattresses, and two pairs of inflatable bags could be used in con~unction with double or larger sized mattresses.
Referring to Figs. 4 and S, the air distribution unit 8 of the preferred embodiment is characterized by three internal compartments, namely two chambers 28 and 29, separated from each other by a divider 30, with a fan 32 installed centrally in the divider and extending through the divider into both chambers. A third chamber, namely air delivery chamber 34, is positioned alongside the chambers 28 and 29. The external walls of the chambers 28 and 29 each have an external air vent, 36 and 37 respectively, and adjacent each vent is mounted a solenoid and plunger unit 38 with attached plug 40. The internal walls of chambers 28 and 29 each have vents 42 and 43 respectively, leading to the air delivery ahamber 34. The external wall of air delivery chamber 34 has four air delivery vents 46, adjacent each of which is mounted a ~olenoid and plunger unit 38 with attached plug 40.
The inflatable bags 6 are inflated by air drawn in through the air distribution unit 8 and delivered to the bags via the tubing 12. Referring to Figs. 4 and 5, arrows delineate air flow. Fig. 4 illustrates inflation, and Fig. 5 illustrates deflation. The position of the "head~foot" switch 60 and of the "left/right" switch 62 of the control unit 64 sh~wn in Fig. 6 determines which one of the four air delivery vents 46 is opened via the solenoid units. With the illustrated controls, only one can be open at any given time. The "up/down" switch 66 has three positions, namely a central "off" position, and up and down positions to either side of the off position.
The switch is spring loaded to the off position, so that : ~- .- , , ~ . .. -201L3~ O
releasing the switch produces neither inflation nor deflation. Selecting the "up" position (Fig. 4) causes vents 36 and ~3 to open and the fan to operate. This draws air in through the vent 36 and out the vent 43 to the selected vent 46. Selecting the ~down" position (Fig. 5) causes vents 37 and 42 to open and the fan to operate. This draws air from the selected air bag via the vent 46, out through vent 42, and then out through vent 37.
10It will be appreciated that the above description relates to the preferred embodiment by way of example only. Many obvious variations could be envisioned by a person with knowledge in the art, and such variations are considered to be within the scope of the invention as described and claimed, whether or not expressly described.
For example, one such anticipated alternative embodiment is depicted in Fig. 7. In this alternative embodiment of the air distribution unit, the direction of air flow is controll4d by the position of a plunger assembly or spool valve 50. Fig. 7 shows with solid lines the position of the plunger assembly 50 and the air flow when the plunger assembly 50 is positioned to deflate the selected air bag. The air is drawn from the -air bag, through the spool valve to the chamber 28, and out the outlet 70. The ghosted lines show the spool valve in the position to inflate the selected air bag.
In the inflate position, the air is drawn in through the inlet 72j and thence through the spool valve to the air delivery chamber and thus to the selected bag.
In another alternative em~odiment, illustrated -~
in Figs. 8 and 9, instead of there being support means such as the hinged panels, and instead of a flexible mattress being positioned above the panels, an inflated air mattress ~0 or other semi-rigid structure can . . , 2~1 3~0 constitute the support means, in which case no separate mattress is required. If fully inflated, the air mattress provides sufficient rigidity that a rigid structure such as provided by the panels, though preferable, may be avoided.
It will also be appreciate~ that the hand held control for the on/off switches governing the raising and lowering of the head and foot sections of the mattress, if one ls provided, need not be operated by electrical connections, ~ut instead may operate by remote control via radio signalling means. The controls could obviously be adapted, if desired, to permit inflation or deflation of more than one section simultaneou~ly.
