Abstract
A security device for a door in a doorway. The device includes a floor-carriable portion and a door-carriable portion magnetically co-operable with the floor-carriable portion to stop the door opening past a communication position at which the door is positioned to guard the doorway and ajar to enable the communication via the doorway. At least one of the floor-carriable portion and the door-carriable portion is reconfigurable to allow the door to open past the communication position.
Claims20
A security device, for a door in a doorway, comprising:
- a floor-carriable portion comprising a blocking member;
- a door-carriable portion comprising:
- an operative portion, and
- a mounting arrangement by which the operative portion is mountable to move, to differing radii relative to an axis of a hinge of the door, between:
- a first position where the operable portion interfaces with and is configured to magnetically co-operate with the floor-carriable portion to lift the blocking member, to a blocking position, to act as a stop for the door in a communication position to stop the door opening past the communication position and
- a second position where the door-carriable portion is offset from the floor-carriable portion to allow the door to open past the communication position;
- and
- a further floor-carriable portion
- configured to magnetically cooperate with the operative portion in the second position to stop the door opening past an open position beyond the communication position.
A method of stopping a door of a doorway opening past a communication position at which the door is:
- positioned to guard the doorway;
- and
- ajar to enable the communication via the doorway,
- the method comprising using a security device, the security device comprising:
- a floor-carriable portion comprising a blocking member;
- a door-carriable portion;
- and
- a further floor-carriable portion;
- wherein a door-carriable portion comprises:
- an operative portion, and
- a mounting arrangement by which the operative portion is mountable to move, to differing radii relative to an axis of a hinge of the door, between
- a first position where the operable portion interfaces with and is configured to magnetically co-operate with the floor-carriable portion to lift the blocking member, to a blocking position, to act as a stop for the door in the communication position to stop the door opening past the communication position and
- a second position where the door-carriable portion is offset from the floor-carriable portion to allow the door to open past the communication position;
- and
- the further floor-carriable portion is magnetically co-operable with the operative portion in the second position to stop the door opening past an open position beyond the communication position.
A security device for a door in a doorway, the device comprising:
- a floor-carriable portion;
- and
- a door-carriable portion comprising:
- an operative portion magnetically co-operable with the floor-carriable portion to limit opening of the door to stop the door opening past a communication position at which the door is:
- positioned to guard the doorway;
- and
- ajar to enable communication via the doorway;
- and
- a mounting arrangement by which the operative portion is mountable to move, to differing radii relative to an axis of a hinge of the door, between
- a first position where the operable portion interfaces with and is configured to magnetically co-operate with the floor-carriable portion to lift a blocking member, to a blocking position, to act as a stop for the door in the communication position to stop the door opening past the communication position and
- a second position where the door-carriable portion is offset from the floor-carriable portion to allow the door to open past the communication position.
