Abstract

Claims (17)

1. A rescue tool adapter for a powered two-armed rescue tool utilized for opening metal doors, comprising:

said adapter having first and second end portions;

said first end portion being of general U-shaped configuration lying generally in a plane, and having first and second legs, said first leg having a length, and said second leg having a length;

said first and second legs being spaced apart a distance greater than the thickness of a door to be opened;

said second end portion being connectable to an arm of the rescue tool at one end and being connectable to the adapter first end portion at the other end and being substantially perpendicular to said plane; and

said adapter being further designed to transmit a pulling force in a lateral direction, away from a door frame, thereby forcing the door to open in a lateral direction, away from the door frame.

2. A rescue tool adapter, as set forth in claim 1 , wherein the length of the second leg is longer than the length of the first leg.

3. A rescue tool adapter, as set forth in claim 1 , including a leg extension being connectable between the first end portion and the second end portion, said leg extension being connectable at a first end to the second leg of the first end portion of the adapter and at a second end to the second end portion of the adapter.

4. A rescue tool adapter for mounting on a powered two-armed rescue tool utilized for force-opening a door, comprising:

a first end portion, the first end portion comprising:

a first leg having a first length, said first leg further having a first end and a second end, said first leg further having an inside surface whereby the first leg inside surface can be used to apply force to an inside portion of a door, the first leg inside surface being orientable generally perpendicular towards a lateral direction, away from a door frame;

a second leg having a second length, said second leg having a first end and a second end, said second leg being substantially parallel to said first leg, said second leg further having an inside surface being generally oriented in a direction facing the first leg inside surface;

a third portion having a third length, a first end and a second end, the third portion being usable to span a thickness of the door, the third length being generally longer than the thickness of the door at which the adapter may be operatively positioned, the third portion being orientable generally in alignment with said lateral direction, away from the door frame, said third portion forming a U-shaped configuration with the first leg and the second leg, wherein the first leg second end is coupled to the third portion first end at a substantially perpendicular angle, wherein the second leg second end is coupled to the third portion second end at a substantially perpendicular angle, said first leg, second leg and third portion all lying generally in a first plane, said first leg having said first leg first end pointing generally away from the third portion and said second leg having said second leg first end pointing generally in the same direction as the first leg first end;

said adapter being connectable at the second leg first end to a first arm of the rescue tool at a substantially perpendicular angle, with said rescue tool first arm lying in a second plane generally perpendicular to said first plane, the rescue tool having a second arm operable to be braced against the door frame, said adapter being designed to transmit a pulling force in the lateral direction, away from the door frame, from the first arm of the rescue tool through the second leg, then through the third portion, then through the first leg to the inside portion of the door, thereby forcing the door to open in a lateral direction, away from the door frame.

5. The rescue tool adapter of claim 4 , for mounting on a powered two-armed rescue tool utilized for force-opening a door by applying a pulling force in the lateral direction, further comprising a second end portion having a first end and a second end, wherein said second end portion first end is connectable to the second leg first end, said second end portion being oriented substantially perpendicular to the second leg and lying generally in the second plane in general alignment with the first arm of the rescue tool, and wherein the second end portion second end is connectable to the first arm of the rescue tool, wherein said second end portion elongates a distance between the first end portion of the adapter and the rescue tool.

6. The rescue tool adapter of claim 4 , for mounting on a powered two-armed rescue tool utilized for force-opening a door by applying a pulling force in the lateral direction, which is away from the door frame, wherein the second length of the second leg is longer than the first length of the first leg.

7. The rescue tool adapter of claim 4 , for mounting on a powered two-armed rescue tool utilized for force-opening a door by applying a pulling force in the lateral direction, which is away from the door frame, further comprising a second leg extension portion having a first end and a second end, wherein said second leg extension portion first end is connected to the second leg first end, said second leg extension portion being oriented generally in alignment with the second leg and lying generally in the first plane, and wherein the second leg extension portion second end is connectable to the first arm of the rescue tool at a substantially perpendicular angle, with said rescue tool first arm lying in a third plane perpendicular to said first plane and parallel to said second plane, wherein said second leg extension portion elongates a second distance between the second leg of the adapter and the powered two-armed rescue tool.
