Abstract
A portable, tactical building door opener which comprises a door opening mechanism comprising: a body; a door opening arm pivotally connected to the body at a first end and having a roller for engaging the surface of the door at a second end; and an actuator for rotating the door opening arm with respect to the body, from a ready position in which the roller is not forced against the surface of the door, to a door-opened position in which the roller is forced against the surface of the door to open the door. The actuator is remotely and manually operable. The device further includes a support for temporarily and removably bracing the door opening mechanism with respect to the door.
Claims15
A portable, tactical building door opener for opening a door, comprising:
- a door opening mechanism comprising:
- a body;
- a door opening arm pivotally connected to said body at a first end and having a roller for engaging the surface of said door at a second end;
- and
- an actuator for rotating said door opening arm with respect to said body, from a ready position in which said roller is not forced against the surface of said door, to a door-opened position in which said roller is forced against the surface of said door to open said door;
- said actuator being remotely and manually operable;
- and
- support means for temporarily and removably bracing said door opening mechanism with respect to said door, wherein said support means comprises a spreader bar positioned within a frame of said door.
A portable, tactical building door opening system for opening a door, comprising:
- means for unlatching said door;
- a door opening mechanism comprising:
- a body;
- a door opening arm pivotally connected to said body at a first end and having a roller for engaging the surface of said door at a second end;
- and
- an actuator for rotating said door opening arm with respect to said body, from a ready position in which said roller is not forced against the surface of said door, to a door-opened position in which said roller is forced against the surface of said door to open said door;
- said actuator being remotely and manually operable;
- support means for temporarily and removably bracing said door opening mechanism with respect to said door;
- wherein said support means comprises a spreader bar positioned within a frame of said door;
- and
- means for operating said means for unlatching said door and said actuator manually and remotely.
A method of opening a building door comprising the steps of:
- mounting a portable, tactical building door opener to the frame of said door, said door opener comprising:
- a door opening mechanism comprising:
- a body;
- a door opening arm pivotally connected to said body at a first end and having a roller for engaging the surface of said door at a second end;
- and
- an actuator for rotating said door opening arm with respect to said body, from a “ready” position in which said roller is not forced against the surface of said door, to a “door-opened” position in which said roller is forced against the surface of said door to open said door;
- said actuator being remotely and manually operable;
- and
- support means for temporarily and removably bracing said door opening mechanism with respect to said door;
- and
- mounting a means for unlatching said door, to a handle of said door;
- routing a single line through said means for unlatching said door, and to said actuator on said door opening mechanism;
- and
- pulling said single line, thereby unlatching said door and operating said actuator so that it rotates said door opening arm from said “ready” position to said “door-opened” position.
