Abstract
A hinge for a range door and the like having a frame bracket (18) adapted to be mounted to a range housing, a hinge arm (40) adapted to be mounted to a range door and pivotably mounted to the frame bracket (18) and a cam follower arm (16) pivotably mounted to the frame bracket (18). A cam follower element (76) on the cam arm (60) is biased by a tension spring (80) against a cam surface on a cam arm portion (46) of the hinge arm to counterbalance the weight of the range door. The cam surface has indentations (50, 52) which define equilibrium positions of the door for an ajar and fully open position. A tab stop (34) is struck out from the frame bracket (18) to stop the pivotable movement of the cam follower arm (60) as the hinge arm (40) reaches the fully open position (FIG. 5). The cam follower arm (60) has a number of indentations (64) for receiving one end (84) of the spring (80) to adjust the counter-balancing force on the oven door.
