Low-Friction Spacer System for Vacuum Insulated Glass

摘要

An insulated glazing unit including a first glass element and a second glass element having congruent shapes. The insulated glazing unit also includes a plurality of elongated spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element. The spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element, and each spacer is elongated along an axis. The spacers are oriented on the surface such that the axis of each of the spacers is tangent to one or more imaginary circular lines superimposed on the surface and having a common center.

1. An insulated glazing unit comprising:
a first glass element; a second glass element, the first and second glass elements having congruent shapes; and a plurality of spacers disposed between the first glass element and the second glass element to space the first glass element from the second glass element, each of the spacers elongated along an axis, wherein the spacers are in rolling, line contact with a surface of one or both of the first glass element and the second glass element such that the spacers are configured to roll about their axis in line contact with the surface, and wherein the spacers are oriented on the surface such that the axis of at least one of the spacers is tangent to an imaginary circular line superimposed on the surface, and at least another of the spacers is tangent to the same imaginary circular line or a different imaginary circular line having a common center with the first imaginary circular line.
