WINDOW STRUCTURE FOR MASS TRANSIT VEHICLE

摘要

A public transit vehicle has a vehicle body having a roof defining an interior ceiling surface, two side walls each extending longitudinally of th e vehicle including an upper side wall portion connecting to the roof and a row of windows underneath the upper portion, a central aisle and two rows of seats each on a respective side of the aisle and along the side wall at the windows. Each window comprises an outer pan attached into the window opening in the frame and a pane structure pivotally mounted in the pan. The pan is formed by four sides each of which is integrally defined by a web bridging the width of the frame, an exterior flange projecting outwardly and an interior flange projecting inwardly with the pan held in place by adhesive between the exterior surface of the frame and the exterior flange and between the web and the corresponding surface of the frame. The p an is thus imperforate to prevent moisture penetration. The pane includes an external frame sealed relative to the pan sides by three separate seals. The pane is suspended from a pivot at the top and is latched by latches in the bottom frame of the pane.
