Abstract
Abstract The device comprises a canopy coextensive with a bed which canopy is supported by a vertically movable member adapted to raise it from, and lower it onto, the bed. The upper surface of the canopy carries a fabric material which covers the bed when the canopy is in the lowered position. The lower surface of the canopy may be provided with heating or cooling means for warming or cooling the bed surface.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
147 words
In combination therewith, a bed, a mattress on said bed, said mattress having an upper surface, a flat sheet disposed over said upper surface of said mattress, said flat sheet being of substantially the same size and shape as said upper surface of said mattress, motion transmission means connected to said sheet for selectively lowering said sheet into contact with said upper surface of said mattress and raising said sheet directly above said mattress and spaced therefrom, said sheet-comprising bedspread means for substantially covering said upper surface of said mattress when said sheet is lowered into contact with said upper surface to obviate the need for other external bed coverings for said mattress, and said sheet-comprising canopy means when said sheet is raised away from said mattress and spaced therefrom to obviate the need for storing said sheet remote from said bed during use of said bed.
Claim 2
Dependent Claim
147 words
In combination therewith, a bed, a mattress on said bed, said mattress having an upper surface, a flat sheet disposed over said upper surface of said mattress, said flat sheet being of substantially the same size and shape as said upper surface of said mattress, motion transmission means connected to said sheet for selectively lowering said sheet into contact with said upper surface of said mattress and raising said sheet directly above said mattress and spaced therefrom, said sheet-comprising bedspread means for substantially covering said upper surface of said mattress when said sheet is lowered into contact with said upper surface to obviate the need for other external bed coverings for said mattress, and said sheet-comprising canopy means when said sheet is raised away from said mattress and spaced therefrom to obviate the need for storing said sheet remote from said bed during use of said bed.
Claim 3
Dependent Claim
28 words
A combination as claimed in claim 1, in which said transmission means comprises one or more vertically extensible and retractable posts disposed at the periphery of said bed.
Claim 4
Dependent Claim
22 words
A combination as claimed in claim 2, in which said posts are telescopic tubes disposed at the four corners of said bed.
Claim 5
Dependent Claim
31 words
A combination as claimed in claim 2, in which said posts comprise a pair of telescopic tubes disposed at one end of said bed, said sheet being cantilevered from said posts.
Claim 6
Dependent Claim
38 words
A combination as claimed in claim 1, in which said transmission means is a vertically movable member supporting said sheet and having a collar slidably disposed around a vertical post fixedly mounted at one end of said bed.
Claim 7
Dependent Claim
32 words
A combination as claimed in claim 1, in which an end portion of said sheet is shaped to engage and cover a pillow placed onto a corresponding end portion of said bed.
Claim 8
Dependent Claim
42 words
A combination as claimed in claim 1, in which at least one curtain extending downwardly from the periphery of said sheet to said bed when said sheet is in the raised position, and position adjusting means for lowering and raising said curtain.
Claim 9
Dependent Claim
30 words
A combination as claimed in claim 1 wherein said sheet has a depending skirt about a portion of its periphery of sufficient length to cover the sides of said mattress.
Claim 10
Dependent Claim
41 words
A combination as set forth in claim 8 in which said skirt is longer than said sides of said mattress but sufficiently short so as not to be draped on the floor when said sheet is in contact with said mattress.
Claim 11
Dependent Claim
19 words
A combination as claimed in claim 8 in which said sheet is substantially imperforate, and said skirt being pleated.
Claim 12
Dependent Claim
23 words
A combination as claimed in claim 7 in which said position adjusting means include shade-type rollers mounted along the periphery of said sheet.
Claim 13
Dependent Claim
15 words
A combination as claimed in claim 1 in which said sheet incorporates temperature control means.
Claim 14
Dependent Claim
28 words
A combination as claimed in claim 12, in which the lower face of said sheet is provided with electrically energized heating means to comprise said temperature control means.
Claim 15
Dependent Claim
28 words
A combination as claimed in claim 12, in which the lower face of said sheet is provided with electrically energized cooling means to comprise said temperature control means.
Claim 16
Dependent Claim
45 words
A combination as claimed in claim 12 in which said sheet includes cushioning means disposed above said temperature control means for permitting a user to comfortably sit on said sheet above said temperature control means when said sheet is lowered into contact with said mattress.
Claim 17
Dependent Claim
150 words
A bedspread canopy device for use in selectively covering the mattress of a bed and acting as a canopy therefor comprising, a flat sheet, motion transmission means connected to said sheet for selectively lowering said sheet and raising said sheet, securing means for mounting said motion transmission means to a bed in such a manner that said sheet may be lowered into contact with the upper surface of the mattress and may be raised directly above the mattress and spaced therefrom, said sheet-comprising bedspread means for substantially covering the upper surface of the mattress when said sheet is lowered into contact with the upper surface to obviate the need for external bed coverings for the mattress, and said sheet-comprising canopy means when said sheet is raised away from the mattress and spaced therefrom to obviate the need for storing the sheet remote from the bed during use of the bed.
