Abstract
Abstract An apparatus for elevating bedclothes above a bed and for warming the air under the bedclothes. Two hollow, tubular rigid arms are vertically mounted on either side of a bed; one or more flexible, resilient lines span the free ends of the rigid arms to form a structure over which the bedclothes drape. The flexible lines are removable and adjustable. Under the bed is a small air blower with a heating unit. The air blower discharges heated air into the bed through the passages formed in the hollow, tubular rigid arms of the bedclothes elevator.

Claim 1
Independent Claim
235 words
Apparatus for a bed having a mattress and a bed covering, said apparatus being adapted for ventilating the interior space of said bed between the mattress and the bed covering comprising: means for elevating said bed covering above the mattress thereby creating a closed volume bounded by the mattress and the bed covering, said means including first and second rigid arms, each rigid arm having a free end and a pivoting end, means for pivotally attaching said pivoting ends of said rigid arms respectively to opposite sides of a bed to that the free ends of said rigid arms are movable respectively through substantially equal radius arcs, a resilient flexible member having first and second ends, said first end of said flexible member being attached to the free end of said first rigid arm and means for removably affixing said second end of said flexible member to the free end of said second rigid arm so that said flexible member can extend between the free ends of said rigid arms and can overlie the mattress; a conduit operatively connected to said elevating means and having a first end for communication with the closed volume and a second end exterior of said volume; and means for supplying ventilating air to said second end of the conduit at variable temperatures whereby the ventilating air flows from the supplying means, through the conduit and into the closed volume.
Claim 2
Dependent Claim
235 words
Apparatus for a bed having a mattress and a bed covering, said apparatus being adapted for ventilating the interior space of said bed between the mattress and the bed covering comprising: means for elevating said bed covering above the mattress thereby creating a closed volume bounded by the mattress and the bed covering, said means including first and second rigid arms, each rigid arm having a free end and a pivoting end, means for pivotally attaching said pivoting ends of said rigid arms respectively to opposite sides of a bed to that the free ends of said rigid arms are movable respectively through substantially equal radius arcs, a resilient flexible member having first and second ends, said first end of said flexible member being attached to the free end of said first rigid arm and means for removably affixing said second end of said flexible member to the free end of said second rigid arm so that said flexible member can extend between the free ends of said rigid arms and can overlie the mattress; a conduit operatively connected to said elevating means and having a first end for communication with the closed volume and a second end exterior of said volume; and means for supplying ventilating air to said second end of the conduit at variable temperatures whereby the ventilating air flows from the supplying means, through the conduit and into the closed volume.
Claim 3
Dependent Claim
235 words
Apparatus for a bed having a mattress and a bed covering, said apparatus being adapted for ventilating the interior space of said bed between the mattress and the bed covering comprising: means for elevating said bed covering above the mattress thereby creating a closed volume bounded by the mattress and the bed covering, said means including first and second rigid arms, each rigid arm having a free end and a pivoting end, means for pivotally attaching said pivoting ends of said rigid arms respectively to opposite sides of a bed to that the free ends of said rigid arms are movable respectively through substantially equal radius arcs, a resilient flexible member having first and second ends, said first end of said flexible member being attached to the free end of said first rigid arm and means for removably affixing said second end of said flexible member to the free end of said second rigid arm so that said flexible member can extend between the free ends of said rigid arms and can overlie the mattress; a conduit operatively connected to said elevating means and having a first end for communication with the closed volume and a second end exterior of said volume; and means for supplying ventilating air to said second end of the conduit at variable temperatures whereby the ventilating air flows from the supplying means, through the conduit and into the closed volume.
Claim 4
Dependent Claim
