Abstract
Abstract A liquid bed system comprises: A. A FLEXIBLE HOLLOW ENCLOSURE TO RECEIVE LIQUID AND HAVING A SUBSTANTIALLY FLAT TOP SIZED TO RECEIVE A RECLINING SLEEPER, AND B. RADIANT HEAT PRODUCING BULB MEANS LOCATED AND DIRECTED IN SUCH PROXIMITY TO THE ENCLOSURE AS TO TRANSMIT HEAT FOR TRANSFER TO LIQUID THEREIN THEREBY TO MAINTAIN THE LIQUID TEMPERATURE AT A LEVEL COMFORTABLE TO THE SLEEPER. Also, a flange on the enclosure (in the form of a tray) may transmit imposed loading directly to supports, independently of the remainder of the tray.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
106 words
In a liquid bed system, the combination comprising: a. a flexible hollow enclosure to receive liquid and having a substantially flat top sized to receive a reclining sleeper, b. radiant heat producing bulb means located and directed in such proximity to the enclosure as to transmit heat for transfer to liquid therein thereby to maintain the liquid temperature at a level comfortable to the sleeper, c. an upwardly opening molded plastic tray receiving the enclosure, said bulb means extending below the tray to radiate heat upwardly, and d. metallic sheet means extending over the bulb means and in face-to-face engagement with the under-side of the tray.
Claim 2
Dependent Claim
106 words
In a liquid bed system, the combination comprising: a. a flexible hollow enclosure to receive liquid and having a substantially flat top sized to receive a reclining sleeper, b. radiant heat producing bulb means located and directed in such proximity to the enclosure as to transmit heat for transfer to liquid therein thereby to maintain the liquid temperature at a level comfortable to the sleeper, c. an upwardly opening molded plastic tray receiving the enclosure, said bulb means extending below the tray to radiate heat upwardly, and d. metallic sheet means extending over the bulb means and in face-to-face engagement with the under-side of the tray.
Claim 3
Dependent Claim
31 words
The combination of claim 1 including means supporting the tray above floor level, and a reflector extending below the tray and located to reflect bulb transmitted heat toward the tray underside.
Claim 4
Dependent Claim
20 words
The combination of claim 1 including variable resistance means electrically connected with the bulb means to control current delivery thereto.
Claim 5
Dependent Claim
27 words
The combination of claim 3 wherein the bulb means has maximum radiant heat output capable of maintaining the liquid temperature at a level between 80*F and 110*F.
Claim 6
Dependent Claim
12 words
The combination of claim 1 including said liquid which consists of water.
Claim 7
Dependent Claim
29 words
The combination of claim 1 wherein the tray has an outwardly projecting rim, and there being a protective skirt depending from the rim in bounding relation to the tray.
Claim 8
Dependent Claim
14 words
The combination of claim 6 including support legs receiving loading exerted via the rim.
Claim 9
Dependent Claim
77 words
In a liquid bed system, the combination comprising a. a flexible hollow enclosure to receive liquid and having a substantially flat top to receive a reclining sleeper, b. radiant heat producing bulb means located and directed in such proximity to the enclosure as to transmit heat for transfer to liquid therein thereby to maintain the liquid temperature at a level comfortable to the sleeping, and c. an air-containing sub-enclosure directly underlying liquid in the first mentioned enclosure.
Claim 10
Dependent Claim
77 words
In a liquid bed system, the combination comprising a. a flexible hollow enclosure to receive liquid and having a substantially flat top to receive a reclining sleeper, b. radiant heat producing bulb means located and directed in such proximity to the enclosure as to transmit heat for transfer to liquid therein thereby to maintain the liquid temperature at a level comfortable to the sleeping, and c. an air-containing sub-enclosure directly underlying liquid in the first mentioned enclosure.
Claim 11
Dependent Claim
102 words
In a liquid bed system, the combination comprising: a. a tray structure having a bottom wall to receive loading imposed by a water containing bladder in the tray, and side walls to extend about the bladder, b. a generally horizontal flange peripheralLy extending about the tray structure and connected to the side walls, c. supports extending below the flange to transmit loading imposed on the flange, d. a lengthwise and widthwise elongated metallic sheet extending in heat transfer relation with the bladder at the outside thereof, and e. electrically energized heat producing means located to radiate heat for impinging on said sheet.
Claim 12
Dependent Claim
102 words
In a liquid bed system, the combination comprising: a. a tray structure having a bottom wall to receive loading imposed by a water containing bladder in the tray, and side walls to extend about the bladder, b. a generally horizontal flange peripheralLy extending about the tray structure and connected to the side walls, c. supports extending below the flange to transmit loading imposed on the flange, d. a lengthwise and widthwise elongated metallic sheet extending in heat transfer relation with the bladder at the outside thereof, and e. electrically energized heat producing means located to radiate heat for impinging on said sheet.
