Abstract
A window assembly for a mass transit vehicle adapted to receive a transparent protective member to be positioned adjacent an inner surface of a piece of window glazing by a set of retaining brackets that provide rapid removal of the member without having to remove the retaining brackets. The retaining brackets enclose all four edges of the vehicle window glazing and incorporate a defined space between the window glazing an the inner surface of the retaining brackets. The protective member is positioned within the defined space and can be moved between a secured position and a release position.
Claims18
A window assembly for a mass transit vehicle the assembly comprising:
- a window frame having a plurality of sides wherein the window frame defines aperture and wherein the window frame further defines a channel formed on each the plurality of sides;
- a piece of glazing having an inner surface, an outer surface and an outer perimeter positioned within the aperture of the window frame such that the outer perimeter of the piece of glazing is positioned within the channels and is retained therein;
- a plurality of retainers positioned within the channels on each the plurality of sides of the window frame so as to be adjacent the piece of glazing, wherein the plurality of retainers are configured to define a space adjacent the inner surface of the piece of glazing wherein the space is located adjacent the outer perimeter of the piece of glazing;
- a sacrificial member having an outer perimeter wherein the sacrificial member is positioned adjacent the inner surface of the piece of glazing so as to protect the inner surface of the piece of glazing with the outer perimeter of the sacrificial member being positioned within the space defined by the plurality of retainers wherein the sacrificial member is movable within the space between a secured position and a release position and wherein one edge of the sacrificial member is exposed from the space so as to permit the sacrificial member to be removed when the sacrificial member in the release position;
- and
- a retaining fastener that extends through one of the plurality of retainers so as to inhibit movement of the sacrificial member between the secured and release position.
An assembly of retrofitting existing mass transportation vehicle windows, that have a piece of glazing retained within a channel by a gasket, with a sacrificial protective layer, the assembly comprising:
- at least one retainer that is interposed between the gasket and the piece of glazing, wherein the at least one retainer is positioned on opposite sides of the piece of glazing and wherein the at least one retainer defines a space adjacent the outer perimeter of the piece of glazing when interposed between the gasket and the piece of glazing;
- a sacrificial member having an outer perimeter that is positioned adjacent the inner surface of the piece of glazing when the at least one retainer is interposed between the gasket and the piece of glazing, wherein at least a portion of the outer perimeter of the sacrificial member is positioned within the space defined by the at least one retainer such that the at least one retainer retains the sacrificial member adjacent the piece of glazing and wherein the sacrificial member is sized so as to be movable between a secured position and a release position in the space and wherein an outer edge of the sacrificial member is removed out of the space when the sacrificial member is in the release position so as to permit removal of the sacrificial member;
- and
- wherein the at least one retainer is configurable into a secured configuration such that movement of the sacrificial member between the secured and release position is inhibited and into a release configuration allowing the sacrificial member to move into the release position and be removed from the window without requiring removal of the at least one retainer.
