Truck cab door system for improved right side vision

Abstract

A truck cab door system for increased right side viewing area includes a truck cab door having an inner skin panel and an outer skin panel spaced apart but joined together along the end edges thereof. A relatively large opening in an upper portion of the door skin panels provides a field of vision through a correspondingly dimensioned glass panel of a dropping glass window assembly received between the skin panels and within and closing off the opening when in a raised position thereof. A mechanism for causing selective dropping or raising of the glass panel of the dropping glass window assembly is operatively engaged to a mechanism for supporting the glass panel. A second, comparatively large opening is provided in a lower portion of each door skin panel with a viewing window assembly including a window panel fixed within the second opening of the outer skin panel and a clear panel removably mounted over the second opening of the inner skin panel. The glass panel of the dropping window assembly passes between the fixed window panel and the clear panel when in a dropped position thereof. The mechanism for causing dropping or raising of the glass panel of the dropping glass window assembly is positioned between the inner and outer door skin panels at a location adjacent the large lower opening and is substantially hidden from view through the viewing window assembly. The mechanism for supporting the glass panel is engaged to and extends away from the mechanism for causing dropping and raising of the glass panel and under half of the glass panel to a point of attachment thereto and is of diminutive dimension relative to the large second opening in the inner and outer skin panels.
