Abstract
Abstract A bed having a horizontal portion received beneath a person lying on the bed and through which air is circulated upwardly toward the person, with the bed also having a structure at its end projecting upwardly above the level of the horizontal portion and discharging air from that elevated location generally horizontally toward the person and preferably past an adjustable louver assembly. Both types of circulation are preferably produced by a fan contained within the mentioned end structure.

Total Claims: 13
Claim 1
Independent Claim
247 words
In a bed, the combination comprising: a body supporting assembly having a mattress-top surface on which a person using the bed rests and which is cushioned to yieldingly support and be dformed by the user''s weight, and is constructed to pass air upwardly through said mattress-top surface to the user''s body, said assembly including means forming a chamber or plurality of chambers beneath said surface adapted to conduct a circulation of air and from which said air may flow upwardly through said mattress-top surface and to the user; a hollow housing at an end of said body supporting assembly communicating with said chamber or chambers beneath the mattress-top surface in a relation delivering air thereto along a first path, said housing having an upper portion projecting upwardly to a level above that of said mattress-top surface and containing an air discharge outlet through which air discharges along a second path at a level above that of said mattress-top surface in a direction to flow over a person lying thereon; and power driven fan means within said housing at said end of the body supporting assembly and operable to produce two different flows of air from said housing, one being along said first path from the housing through said chamber or chambers and then upwardly through said mattress-top surface to the user, and the second flow being from the housing along said second path and through said discharge outlet above the mattress-top level and over the user''s body.

Claim 3
Dependent Claim
30 words
The combination as recited in claim 1, in which said power driven fan means includes a common fan within said housing operable to discharge air alOng both of said paths.
Claim 4
Dependent Claim
26 words
The combination as recited in claim 1, including means for controlably varying the proportion of air discharged by said fan means along said two paths respectively.
Claim 5
Dependent Claim
21 words
The combination as recited in claim 1, including means for controlably varying the quantity of air delivered through said discharge outlet.
Claim 6
Dependent Claim
21 words
The combination as recited in claim 1, including louver means adjustable to regulate the flow of air along said second path.
Claim 7
Dependent Claim
26 words
The combination as recited in claim 1, including means within said housing for changing the temperature of air flowing along at least one of said paths.
Claim 8
Dependent Claim
24 words
The combination as recited in claim 1, including means within said housing for changing the temperature of air flowing along both of said paths.
Claim 9
Dependent Claim
34 words
The combination as recited in claim 1, in which said fan means include a common fan contained within said upwardly projecting portion of said end structure and discharging air along both of said paths.
Claim 10
Dependent Claim
35 words
The combination as recited in claim 8, in which said air discharge outlet faces generally toward a person lying on the bed there being louvers in said outlet adjustable to variably control the airflow therethrough.
Claim 11
Dependent Claim
82 words
The combination as recited in claim 9, in which said upwardly projecting portion of said housing contains an opening at a backside thereof facing away from the bed and through which air is drawn inwardly by said fan, said fan being positioned to direct discharged air generally horizontally towards said louvers, there being a temperature changing element within said housing past which air is circulated by the fan and acting to controlably change the temperature of the air circulated by said fan.
Claim 12
Dependent Claim
72 words
The combination as recited in claim 10, in which said means forming said chamber or chambers includes a hollow rectangular structure connected at one end to said housing to receive air therefrom and having openings at its upper side through which air circulates upwardly, said body supporting assembly including a box spring beneath said hollow structure and a mattress above said hollow structure and having said mattress-top surface at its upper side.
