ABSTRACT:
An arm assembly (10) having first and second arms (20,22), a first apparatus (26) and an adjusting element (24) is used to adjustably hold open a door (18), window, or the like on a work vehicle (12), for example. In the harsh environment of the work vehicle (12), the door (18) must be securely held open. The first apparatus (26) pivotally connects the first and second arms (20,22). The second arm (22) has an opening (46) alignable with an opening (44) of the first arm (20) in response to moving one of the arms (20,22). A member (48) has a first end portion (50) and is connected to the first apparatus (26). The member (48) is movable between a first position (54) at which the first end portion (50) is positioned in the openings (44,46) of the first and second arms (20,22) for maintaining the door (18) in an open position and a second position (56) at which said first end portion (50) is spaced from the second arm opening (46) for changing the door position.
