TUG VEHICLE WITH REAR CORNER WINDOW

摘要

A corner window for use in tug type truck vehicles through which a driver can engage and disengage air lines and electrical hookups to a truck trailer. A number of individual window panes are hinged together, and rollers at the tops and bottoms of the couplings travel within tracks forming the bottom and top window casings. At least one sheet of flexible insulation material is arranged adjacent to the exterior of each window at the upper and lower tracks. The insulation material deforms to remain in continuous sealing contact with the window as the panes project beyond the tracks as the window negotiates the curves in the tracks.
