Door for an operator's cab on an agricultural tractor

摘要

A door for the operator's cab on an agricultural tractor is formed from a frameless single pane of transparent material pivoted at one edge on a pillar of the tractor. The pivot is formed of two hinges affixed to the pane and a reinforcing member extending generally parallel to the pivot axis and interconnecting the wings of the hinges that are affixed to the pane. The reinforcing member is arranged in line with the pillar on which the door is mounted, when viewed from the position of the driver of the vehicle, so as to minimize obstruction of the field of view of the driver. In another aspect of the invention, the surfaces on the hinges that mate with the pane are machined to match the contours of the pane while the reinforcing member and the hinges are in one piece.
