Abstract
There is a temperature activated spring hinge comprising hinge section comprising at least one door leaf and at least one hinge leaf. There is also a fuse which is configured to react in response to an elevated temperature. The fuse can be positioned inside one of the knuckles of the door leaf. There is also a biasing element configured to bias the hinge in a closed position. In at least one embodiment the biasing element is a spring. There is also at least one guide configured to guide a movement of the hinge when the hinge moves from an open position to a closed position.
Claims8
A selectively closable hinge comprising:
- a hinge comprising a door leaf and a frame leaf, wherein each of said door leaf and said frame leaf comprises a knuckle;
- a fuse which is configured to react in response to an elevated temperature;
- a biasing element configured to bias the hinge into a closed position;
- a locking pin configured to selectively engage a knuckle of said door leaf or said frame leaf;
- and
- a guide configured to guide a movement of said locking pin and said hinge when the hinge moves from an open position to the closed position;
- and
- wherein the biasing element is a torsion spring, said guide is a channel, and wherein the hinge further comprises a gear, wherein said torsion spring is biased in a first position by pressure from said fuse, and said gear is positioned in a disengaged position, wherein when a temperature reaches a predetermined level, said fuse becomes compromised, said torsion spring, is released from said first position, and wherein said gear moves from a disengaged position to an engaged position thereby allowing said gear in combination with said torsion spring to drive the hinge to a closed position.
