Abstract
The CHAR (Climb, Hook And Rip) is a multipurpose tool used by interior structural firefighters to accomplish common essential tasks such as pulling down ceilings, and breaching walls. In addition, it facilitates a quick advancement into the attic of a structure to extinguish fire extension. The innovation is that the CHAR's unique head secures the tool to dimensional 2 lumber, common to wood framed dwelling structures. The head allows an interior firefighter to hook floor and ceiling joists and climb the tool itself to reach another level of the structure. Most likely the tool is used to rip down the ceiling, hook the ceiling joist and climb up to the attic. In a worst-case scenario such as a firefighter falling through the floor, the firefighter may be able to hook a floor joist and climb up the tool to self-rescue.
Claims
2: The head of the tool is designed with a point at the top to break through various building material and with a downward sweeping hook that grips onto floor and ceiling joists. The bottom opening of the hook is 2 inch wide and reduces to a 1 wide. There are two rows of serrated teeth welded to the inside of the downward hook. The hook's designed allows a firefighter to attach the tool to a 2-inch thick dimensional lumber; the hook tightens and its teeth dig in deeper into the lumber as force and weight are apply downward to the pegs of the tool.

DETAILED DESCRIPTION OF THE INVENTION
[0017] The CHAR Fire Fighting, Climbing and Demolition Hook is 6.5 feet long tool constructed entirely of steel with each component welded to the tool (see FIG. 1). There is a 6-foot-long pole which is 1 inches in diameter. On top of the pole there is a -inch-thick head that extends 4 inches to a sharpened point (see FIG. 2). The head is 4 inches wide with a portion that drops down 5 inches angling away from the pole, creating the hook. The hook has two rows of inch thick serrated teeth. One row of teeth is welded to each side of the hook (see FIG. 3). The pole has a single row of inch serrated teeth, located 3 inches down from the top of the pole were the head is inserted and welded to the pole. The bottom opening of the hook is 2% inch-wide and reduces to a 1 wide at the top of the hook opening. There are two 4-inch-long, 1-inch-wide and -inch-thick metal pegs that are welded to the pole area; and one 4-inch-long, 1-inch-wide and -inch-thick metal peg that is inserted and welded to the base of the pole. This lowest/first peg has a two prong % inch long fork at the bottom. The other two pegs are welded to the pole on alternating sides 18 inches apart. The second peg is 18 inches from the bottom, and the third peg is 36 inches from the bottom. cm 1: The CHAR Fire Fighting, Climbing and Demolition Hook is a 6.5 foot multipurpose tool designed for firefighters to (1) manually break through building materials such as dry wall, lath and plaster, or wood; and (2) to hook and attach the tool onto a wood floor or ceiling joist in order to climb up the tool to the level above.
