DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to spacer elements for insulated glass assemblies having a single as well as a divided atmosphere therebetween.
BACKGROUND OF THE INVENTION
The prior art provides a complete plethora of insulated glass assemblies, sealant strips and spacer elements and improvements thereto used in insulated glass assemblies.
The modifications and improvements to the strips etc. have all had a common goal, namely, to improve the insulation capacity for such assemblies without sacrificing structural integrity or moisture degradation of the assembly.
Although the art is replete with such assemblies, it fails to provide an insulating sealant strip which provides:
Typical of the art in the field of the present invention includes U.S. Pat. No. 4,576,841. This patent discloses the use of an aluminum foil into which is positioned desiccant material. Such an arrangement has two inherent limitations, namely: and thus obvious energy expenditures and lites engaged with the same is negligible.
Further, U.S. Pat. No. 4,113,905 discloses a composite foam spacer comprising an extruded tubular profile having an outer coating of foam material thereon. The spacer further includes projecting edges which project laterally relative to the longitudinal axis of the spacer. Although a useful arrangement, the spacer does not facilitate compression dampening and, if the spacer were compressed, this would result in unnatural force dispersion due to the projecting edges which may lead to breakage of the substrates. Further, if compressed, the spacer element may disrupt sealant material associated therewith thus leading to an ineffective seal.
Mucaria, in U.S. Pat. No. 4,368,226 provides a glass assembly in which there is included aluminum spacers. As such, the arrangement is limited similar to U.S. Pat. No. 4,576,841 as discussed herein previously.
Further prior art in the field of the present invention includes U.S. Pat. Nos. 4,536,424; 4,822,649; 4,952,430; 4,476,169; 4,500,572; and Canadian Patent Nos. 884,186; 861,839; and 1,008,307.
SUMMARY OF THE INVENTION
Thus, having regard to the prior art arrangements, there exists a need for a sealant strip which provides a partitioned atmosphere, high insulation value and hygroscopic capabilities without creating an unnecessarily complicated arrangement; the present invention fulfils this need. According to one object of the present invention, there is provided an insulated glass spacer element comprising a pair of spaced apart substrate engaging members each having a top and bottom surface; a base extending between and connected to each bottom surface of each of the substrate engaging members; and a support member extending between the substrate engaging member and connected to the top surface of one of the substrate engaging members.
The spacer element is preferably a fabricated from a resiliently deformable material to allow flexure of the same.
In a preferred form, the support member extends diagonally between the substrate engaging surfaces to partition the area therebetween. Applicant has found that such an arrangement is well suited to dampening compression between substrates engaged therewith in an insulated glass assembly and accordingly, it is a further object of the present invention, to provide an insulated glass assembly comprising a pair of glass lites; an elastically deformable body having a first substrate engaging member associated therewith; a second substrate engaging member spaced from the first substrate engaging surface, the second substrate engaging surface being operatively associated with the body and extending therefrom, whereby when a glass lite is engaged with the first substrate engaging member and the second substrate engaging member, the second substrate engaging member facilitates limited resilient compression of the assembly.
The spacer element according to a further embodiment of the present invention may be used in combination with a similar spacer element to provide a multiple atmosphere insulated assembly. Such
