Abstract
A backhoe loader has an enclosed cab, the opposite sides of which are essentially formed by large side windows. Each side window is formed by front and rear window panels that are mirror images of one another and are joined at their inner edges by a vertical hinge structure that permits either the front or rear window panel to swing 180.degree. from a closed to an open position, one window panel being closed while the other is fully opened. The hinge structure is formed by a pair of pivots respectively attached to the upper and lower portions of the window frame and a pair of relatively narrow hinge elements swingable on the pivot pins. The window panels have their inner edges secured to their respective hinge elements by an adhesive, and the hinge elements have inner edges that abut one another when both panels are in their closed position, a seal being provided along the inner edge one hinge element and being compressed by the inner edge of the other hinge element when the windows are in their closed condition.
