Abstract

Disclosed is a window assembly for use in mass transit vehicles which allows the quick and easy removal and replacement of transparent sacrificial glazing panels which protect the glazing of the window from vandalism and wear. The window assembly utilizes a sacrificial protective panel and mounting arrangement which allows quick and easy replacement of protective panels on one or both sides of the window assembly, but inhibits removal by non-maintenance personnel such as vandals. The frame of the window assembly incorporates one or more retainers which fit into slots along the interior sides of the window frame and sandwich the glazing between the frame and the retainers. In turn, the retainers are essentially “locked” into position in the frame by an inner protective panel, which significantly inhibits the removal of the retainers from the window assembly when the protective panel is in its desired position against the windowpane. Once the inner protective panel is removed from the window assembly, however, the retainers and glazing can quickly and easily be removed from the frame, allowing the glazing and any remaining protective panels to be quickly and easily removed from the frame.

Independent Claims | See all claims (15)

  1. 1. A window assembly for a mass transportation vehicle, the assembly comprising: a piece of glazing having a first and a second side; a first protective panel extending over and protecting the first side of the piece of glazing; a frame defining a frame opening wherein the frame is adapted to receive the piece of glazing so that the piece of glazing can be retained in the frame opening with the first protective panel positioned adjacent the first side of the piece of glazing wherein the frame further defines a retaining opening that is formed in the frame opening and is located adjacent the first protective panel when the piece of glazing and the first protective panel are positioned within the opening; and a retainer having a leg that is positioned in the retaining opening such that the retainer retains the piece of glazing within the frame opening and wherein the retainer is adapted so that when the retainer is positioned in the retaining opening and the first protective panel and the piece of glazing are positioned within the frame opening, the first protective panel inhibits removal of the retainer from the retaining surface.
  2. 11. A window assembly for a mass transportation vehicle, the assembly comprising: a piece of glazing having a first and a second side; a first protective panel extending over and protecting the first side of the piece of glazing; a frame defining a frame opening and having an inwardly extending support face extending into the frame opening wherein the frame is adapted to receive the piece of glazing so that the piece of glazing can be retained in the opening adjacent the inwardly extending support face with the first protective panel positioned adjacent the first side of the piece of glazing wherein the frame further defines a retaining opening framed in the frame opening which is located adjacent the first protective panel when the piece of glazing and the first protective panel are positioned within the opening adjacent the inwardly extending support face; and a retainer having a leg that is positioned within the retaining opening such that the retainer is retained in the retaining opening and such that the retainer extends into the opening of the frame and urges the piece of glazing against the inwardly extending support face so as to retain the piece of glazing in the frame opening in the frame.
