ABSTRACT:
A bracket hinge and bracket members (10, 10') with a spring biased and movable locking member (30). The locking or latch member (30) has ear parts (38, 39) received in locking openings (25, 25') where wedging surfaces (40, 41) on the ear parts cooperate with complimentary surfaces (42, 42') on the bracket members for bringing the bracket members into a tight end-to-end alignment when the bracket members are in an extended position. When the locking member (30) is moved to an unlocking position, pivoting of the hinge about a pivot pin (32) automatically places locking pins (70, 71) in a circular shaped groove (55) on the locking member (30) to retain the locking member (30) in an unlocked position. In pivoting the hinge from an extended position to a folded position, longitudinal spring members (80, 81) are placed under tension over annular rollers (60, 61) so that the spring tension in a folded position assists in return of the hinge from a folded position to an extended position.
