Door, door closing arrangement and door assembly

A two-way door closing arrangement for closing a door located in a doorway aperture, the door being pivotably movable on a pivoting arrangement between a closed position in which the door is substantially in alignment with the doorway aperture, and an open position in which the door is movable out of alignment with the doorway aperture to either side of the doorway aperture, the door closing arrangement comprising:

• a. a door engaging arrangement configured to be connectable to a door and configured to pivot with the door;
• b. a doorway aperture engaging arrangement configured to be rigidly coupled to the doorway aperture;
• c. a biasing arrangement configured for biasing movement of the door engaging arrangement relative to the doorway aperture engaging arrangement in operation to thereby bias movement of the door from an open position on either side of the doorway aperture to its closed position;
• and
• d. wherein the biasing arrangement comprises
• i. a door engaging arrangement;
• ii. a doorway aperture engaging arrangement;
• iii. at least one biasing member extending between the door engaging arrangement and the doorway aperture engaging arrangement;
• and
• iv. wherein the at least one biasing member is configured to be torsioned in use when the door is moved from its closed condition to its open condition.

A two-way door assembly for restricting access through a doorway aperture, the door assembly comprising:

• a. a door member defining a pair of major faces and at least one or more minor faces at a peripheral edge of the major faces, wherein the cross-section of at least one of the minor faces of the door member is configured to be substantially curved, so that in operation when the door is moved between its open position on either side of the doorway aperture and its closed position, the curved minor face remains proximate to at least one peripheral face of the doorway aperture;
• b. a pivoting arrangement configured for facilitating pivotal movement of the door member about a pivot axis, the pivot axis extending through the door member proximate to the pivoting side;
• and
• c. an airflow restricting assembly including a rigid insert and a restrictor arrangement associated with the rigid insert, wherein the airflow restricting assembly is configured to allow for adjustability of a thickness of the restrictor arrangement.

• b. a hinge arrangement;
• c. a door member defining a pair of major faces, the major faces defining at least one straight pivoting side at which at least one curved elongate minor face extends between the major faces;
• d. a hinge arrangement configured for facilitating pivotal movement of the door member about a pivot axis, the pivot axis extending through the door member proximate to the pivoting side;
• and
• e. an airflow restricting assembly including a rigid insert and a restrictor arrangement associated with the rigid insert, wherein the airflow restricting assembly is configured to allow for adjustability of a thickness of the restrictor arrangement.
