Abstract
A door hinge is disclosed including a door mounting bracket and a body mounting bracket interconnected by an intermediate member pivotably attached to each bracket. A locking arrangement including a pivotable locking arm on the intermediate member simultaneously locks and unlocks the intermediate member with the respective mounting bracket at the closed and an intermediate open position of the door providing for sequential, reversible pivotable movement of the intermediate member and door bracket as a unit about the pivot point on the body bracket between the closed and intermediate open position and independent reversible pivotable movement of the door mounting bracket between the intermediate open position and fully open position of the door.
Claims9
A hinge comprising:
- a first mounting bracket adapted to be fixed to a support body and a second mounting bracket adapted to be fixed to a door;
- an intermediate member, one end of the intermediate member being pivotably mounted to said first mounting bracket for relative rotation about a first pivot axis and the other end of the intermediate member being pivotably mounted to said second mounting bracket for relative rotation about a second pivot axis;
- and
- locking means for locking said intermediate member to said second mounting bracket when said intermediate member pivots about said first pivot axis between a closed position and an intermediate position and for locking said intermediate member to said first mounting bracket when said second mounting bracket pivots about said second pivot axis between the intermediate position and a fully open position, said locking means having releasing means for unlocking said intermediate member from the mounting bracket to which it is locked at the intermediate position whereby said intermediate member and said second mounting bracket can pivot about the first pivot axis between the closed and intermediate position and the second mounting bracket can pivot about the second pivot axis between the intermediate and fully open positions.
A hinge comprising:
- a first mounting bracket adapted to be affixed to a mounting member;
- a second mounting bracket adapted to be affixed to a door;
- an intermediate member pivotably connected to said first mounting bracket at a first pivot point and pivotably connected to said second mounting bracket at a second pivot point;
- and,
- means for sequentially releasably locking said second mounting bracket to said intermediate member against relative pivotal movement about said second pivot point and simultaneously providing for pivotal movement of said intermediate member about said first pivot point between a closed position of said door and a predetermined intermediate open position of said door and for releaseably locking said intermediate member to said first mounting bracket against pivotable movement about said first pivot point and simultaneously unlocking said second mounting bracket from said intermediate member at said predetermined intermediate open position providing for pivotable movement of said second mounting bracket about said second pivot point between said predetermined intermediate open position of said door and a fully opened position of said door.
