Abstract
The present invention related to a door jamb finger guard. The finger guard comprises a door lock for preventing closure of the door, a housing for the door lock and a spring activated plate. The spring activated plate is activateable by a door closing obstacle for automatically moving the door lock between an inactive position and an active position. In the inactive position, the door lock is recessed within the housing, while in the active position, the door lock projects from the housing to prevent closure of the door.
Claims22
A door jamb finger guard comprising:
- a door lock for preventing closure of a door, the door lock moving between an inactive and an active position;
- a housing for the door lock;
- a spring activated plate;
- and
- a lever disposed between the door lock and a spring activated plate, the lever maintaining the door lock in the inactive position;
- wherein when the spring activated plate is activatable by a door closing obstacle, it moves the lever to automatically allow the door lock to move from the inactive position in which the door lock is recessed within the housing to the active position in which the door lock projects from the housing to prevent closure of the door.

A door jamb finger guard comprising
- a door lock for preventing closure of a door, the door lock moving between an inactive and an active position;
- a housing for the door lock;
- a detecting means to detect an obstacle located in a gap between the door and a door jamb associated with the door;
- a lever disposed between the door lock and the detecting means, the lever maintaining the door lock in the inactive position;
- wherein when the detecting means is activatable by a door closing obstacle, it moves the lever to automatically allow the door lock to move from the inactive position in which the door lock is recessed within the housing to the active position in which the door lock projects from the housing to prevent closure of the door;
- wherein the finger guard is switchable between an on and an off state and the finger guard is in the on state when the angle of the door relative to the associated door jamb is such that an obstacle placed in the gap would be trapped between the door and the associated door jamb;
- a second detecting means for detecting the angle of the door relative to the door jamb and switching on the finger guard when the detected angle is within one or more predefined ranges wherein the second detecting means comprises a mechanically operated door follower and the position of the door follower at any time being representative of the angle of the door relative to the associated door jamb;
- and
- a first switch and a second switch, wherein the door follower contacts the first switch or the second switch at any one time, wherein when the door follower is in a position so that it is in contact with the first switch, the finger guard is switched on, and when the door follower is in a position so that it is in contact with a second switch, the finger guard is switched off.
