Abstract
Abstract An improved light-transmissive building element useful for walls, ceilings, roofs, windows, or the like consists of at least two light-transmitting flat sheets, such as panels, panes, and the like, which, together with a suitable frame, define a hollow space in which sound- and heat-insulating means are arranged. A number of transparent, static flat sheets, such as foils of plastic or elastically tensioned, flexible, thin plastic panels which may be coated with light-transmissive metal layers or the like are inserted in said hollow space at a small distance from each other.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
163 words
A light-transmissive building element comprising (a) frame means, (b) window panes mounted in transversely spaced relation on said frame means, said panes defining a hollow space therebetween, (c) means for sealing said panes in said mounting in said frame, (d) a plurality of light-transmissive sheets mounted in spaced relation from each other and between said panes in said hollow space, and (e) means for independently and variably elastically tensioning each of said sheets, whereby each of said sheets will vibrate and thus oscillate at a predetermined range of resonant frequencies in response to acoustic energy at said resonant frequency, said resonant frequencies for each of said sheets thus being variable and dependent on the tension applied independently to said sheets, wherein each of said independent elastic tensioning means comprises spring tensioned roller means around which at least one end of each sheet is wound, and resilient tensioning means operatively connecting said roller means and said sheet, with predetermined tension, to said frame means.
Claim 2
Dependent Claim
163 words
A light-transmissive building element comprising (a) frame means, (b) window panes mounted in transversely spaced relation on said frame means, said panes defining a hollow space therebetween, (c) means for sealing said panes in said mounting in said frame, (d) a plurality of light-transmissive sheets mounted in spaced relation from each other and between said panes in said hollow space, and (e) means for independently and variably elastically tensioning each of said sheets, whereby each of said sheets will vibrate and thus oscillate at a predetermined range of resonant frequencies in response to acoustic energy at said resonant frequency, said resonant frequencies for each of said sheets thus being variable and dependent on the tension applied independently to said sheets, wherein each of said independent elastic tensioning means comprises spring tensioned roller means around which at least one end of each sheet is wound, and resilient tensioning means operatively connecting said roller means and said sheet, with predetermined tension, to said frame means.
Claim 3
Dependent Claim
17 words
The building element of claim 1 wherein said sheets are in the form of clear plastic foils.
Claim 4
Dependent Claim
45 words
The building element of claim 1 wherein said window panes each comprise a pair of glass panes spaced from each other and mounted in seals carried by said frame means, the spacing of said panes providing increased sound and insulating capabilities to said building element.
Claim 5
Dependent Claim
96 words
The building element of claim 1 further including a rigid exterior shell enclosing said building element, and said frame means includes a first frame section mounted in sealed relation in said shell, the exterior most window pane being mounted in said first section, and a second frame section mounted in sealed relation in said shell, said second frame section carrying the window pane interiorally positioned in the building element, said first and second frame sections being sealed relative to each other thereby to provide a sealed hollow space defined by said frame sections and said panes.
Claim 6
Dependent Claim
19 words
The building element of claim 1 further including means communicating with said hollow space for conditioning the air therein.
Claim 7
Dependent Claim
45 words
The building element of claim 5 wherein said means for conditioning the air in said hollow space comprises pipe means and valve means by means of which said hollow space can be filled with a dry gas or a vacuum produced in said hollow space.
Claim 8
Dependent Claim
62 words
The building element of claim 5 wherein said means for conditioning the air in said hollow space comprises pipe means and a valve positioned in said pipe means, said pipe means communicating with an air and vapor-tight bag whereby the volume of gas in said hollow space can be maintained substantially constant despite increases and decreases of temperature in said hollow space.
Claim 9
Dependent Claim
63 words
The building element of claim 1 wherein each of said elastic tensioning means further comprises spring means operatively engaging the opposite end of each sheet for resiliently tensioning such end, the degree of unwinding of each of said sheets from said tensioned spring roller and the force of said spring means determining the tension applied to and the resonant frequency of said sheets.
Claim 10
Dependent Claim
64 words
The building element of claim 1 further including guide plates extending vertically in said building element generally perpendicular to said window panes and said sheets, said plates being provided with vertical slots, and said tensioned spring roller being provided with a shaft positioned in said slot thereby to accommodate vertical movement of said spring roller relative to said plates and to said frame means.
Claim 11
Dependent Claim
65 words
The building element of claim 8 further including upper and lower cover plates extending transversely in said building element above and below the normal viewing area through said window panes, said upper cover plate being formed with openings for receiving said sheets, and the bottom cover plate being formed with openings for receiving said spring means operatively connected to the lower ends of said sheets.
Claim 12
Dependent Claim
37 words
The building element of claim 1 wherein at least certain of said sheets are at least partially coated with a reflecting material thereby to reflect radiant energy and consequently increase the insulating characteristic of the building element.
