Abstract
The application describes a frame assembly. The frame assembly comprises: first and second glass panels substantially parallel to each other; and an intermediate ballistic panel positioned between the first and second glass panels. A spacer element is positioned between the first and second glass panels and adapted to receive the intermediate ballistic panel. The spacer element comprises a recess adapted to receive the intermediate ballistic panel therein. The recess is larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel.
Claims25
A frame assembly comprising:
- first and second glass panels substantially parallel to each other;
- an intermediate ballistic panel positioned between the first and second glass panels and comprising a polymeric material;
- and
- a spacer element positioned between the first and second glass panels and adapted to receive the intermediate ballistic panel, wherein a first portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface of the first glass panel and wherein a second portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface the second glass panel,
- wherein the spacer element comprises a recess adapted to receive the intermediate ballistic panel therein, and
- wherein the recess is larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel.
A spacer element for a frame assembly comprising first and second glass panels substantially parallel to each other and further comprising an intermediate ballistic panel positioned between the first and second glass panels and comprising a polymeric material,
- the spacer element being adapted to be positioned between the first and second glass panels and adapted to receive the intermediate ballistic panel, wherein a first portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface of the first glass panel and wherein a second portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface the second glass panel,
- and wherein the spacer element comprises a recess adapted to receive the intermediate ballistic panel therein, the recess being larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel.
A method of constructing a frame assembly having plural parallel panels, the method comprising:
- arranging first and second glass panels substantially parallel to each other;
- positioning an intermediate ballistic panel between the first and second glass panels, the intermediate ballistic panel comprising a polymeric material;
- receiving the intermediate ballistic panel in a recess of a spacer element, the recess being larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel;
- and
- positioning a spacer element between the first and second glass panels such that a first portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface of the first glass panel and such that a second portion of the spacer element is positioned between the intermediate ballistic panel and an inner surface the second glass panel.
