Abstract
A forcible entry tool includes an elongate pry bar having at one end a cutting section comprising a gripping block and a cutting blade. The gripping block has a forward gripping pad which acts as a fulcrum point, about which the tool can pivot. The blade can be thrust towards the material to be cut to pierce through the material, or alternatively, the tool can be swung like an axe to cut through the material. In either event, after an opening is formed in the material, the cutting blade can be inserted into the opening with the gripping block above the material. Continued pumping of the pry bar about the pivot point transfers a cutting force to the cutting blade to shear the material. Alternate tool portions such as prying heads and saw blades can be installed at the opposite end of the bar for various other uses.
Claims19
An emergency forcible entry tool for cutting through sheet material, comprising:
- an elongate pry bar having first and second ends;
- pivot means extending from said first end of said bar;
- a knife member comprising a mounting shank attached to said first end of said bar and a blade portion extending from said mounting shank longitudinally beyond said pivot means and essentially parallel to said bar, said blade portion having a sharpened inner edge facing said pivot means and a sharpened outer opposite edge, said inner and outer edges leading into a sharpened end tip, said sharpened inner edge comprising a first cutting edge extending rearwardly from said tip towards said mounting shank, and a second cutting edge extending from said first cutting edge and angled towards said mounting shank and said pivot means.
An emergency forcible entry tool, comprising:
- a pry bar having first and second ends;
- a first entry tool comprising a knife member having a mounting shank and a blade portion extending from said mounting shank;
- a gripping block removably attached to said first end of said bar, said gripping block having pivot means extending from a forward end thereof and, at the rear end thereof, means for attaching said gripping block to said first end of said bar, said gripping block further comprising means for receiving said mounting shank of said knife member, said gripping block extending in a plane transverse to a plane of said knife member and extending laterally substantially beyond a width of said knife member;
- fastening means for removably attaching said knife member and said gripping block to said first end of said pry bar;
- and
- a second entry tool removably attached to said second end of said bar.
An emergency forcible entry tool, comprising:
- an elongate pry bar having first and second ends;
- pivot means extending from said first end of said bar;
- a cutting device comprising a mounting shank attached to said bar and a blade portion extending from said mounting shank longitudinally beyond said pivot means and essentially parallel to said bar, said blade portion including a sharpened inner edge facing said pivot means, thereby defining a first blade edge;
- and
- a prying portion removably attached to said second end of said bar, said prying portion comprising a block having first and second ends, the first end having an opening for slidable receipt over said second end of said pry bar, said prying portion further comprising top and bottom surfaces and side surfaces, a prying end being defined by a first substantially planar beveled surface extending from said bottom surface towards the center of said prying portion, and a second arcuate surface extending from said top surface converging towards said beveled surface to form a prying tip at the free end of said prying portion, said beveled surface having a roughened gripping surface.
