Releasable pike pole
First Claim
1. In a pike pole used in fire rescue having a shaft that includes a first half and a second half, a handle connected to one end of the shaft that is located on the first half of the shaft, a longitudinal axis, and a cutting-piercing member connected to the other end of the shaft that is located on the second half of the shaft, said cutting-piercing member having a first element extending along the longitudinal axis and having a pointed tip that is located substantially on the longitudinal axis and that points in a direction that is parallel to the longitudinal axis, the improvement comprising:
- an elongated cutting member pivotally connected to the first element and being controllably moveable between a first laterally-oriented position at which the cutting member includes an edge that is located along at least half a length of the cutting member, is oriented substantially perpendicular to the longitudinal axis, and extends further from the longitudinal axis than any other member on the second half of the shaft while forming an opened relationship with the first element, and a second longitudinally-oriented position at which the cutting member extends generally along the longitudinal axis and forming a closed relationship with the first element, the first laterally-oriented position of the cutting member enabling a thrusting and cutting of the pike pole through a building structure followed by a rotating and removal of the pike pole in order to remove portions of the building structure using the edge of the cutting member, and the second longitudinally-oriented position of the cutting member facilitating an extraction of the pike pole from the building structure in response to the edge of the cutting member preventing the removal of the pike pole from the building structure when the cutting member is in the first laterally-oriented position; and
a controlling system connected to the handle and being adjustable between a first position at which the cutting member is maintained at the cutting member first laterally-oriented position and in the opened relationship with the first element, and a second position at which the cutting member is released and pivotally moveable to the cutting member second longitudinally-oriented position and in the closed relationship with the first element;
wherein the controlling system comprises a lever arm pivotally connected to the handle and a pushing element extending between and pivotally connected to the lever arm and the cutting member, said pushing element being moveable towards the cutting member and away from the handle, in response to movement of the lever arm, between a first position at which the cutting member is maintained at the cutting member first laterally-oriented position forming the open relationship with the first element, and a second position at which the movement of the pushing element towards the cutting member and away from the handle moves the cutting member to the second longitudinally-oriented position in which the cutting member forms the closed relationship with the first element.

Abstract
A pike pole has a cutting-piercing member connected to one end of the pole. The cutting member normally extends outwardly from the pike pole. The cutting member can be released by a controlling member and be pivotally moveable to a position extending generally along the piercing member.

19. A fire rescue tool used to penetrate and tear down building structures comprising:
-
an elongated shaft having a first half and a second half, a longitudinal axis, a handle at a proximal end on the first half of the shaft, and a first cutting-piercing element extending substantially parallel to the longitudinal axis and having a pointed tip that points in a direction that is parallel to the longitudinal axis of the shaft at a distal end on the second half of the shaft; a second cutting-piercing element pivotally coupled to the distal end of the shaft, the second cutting-piercing element being controllably moveable between a first laterally-oriented position at which the second cutting-piercing element includes an edge that is located along at least half a length of the cutting member, is oriented substantially perpendicular to the longitudinal axis, and extends further from the longitudinal axis than any other member on the second half of the shaft while forming an opened relationship with the first cutting-piercing element, and a second longitudinally-oriented position at which the second cutting-piercing element extends generally along the longitudinal axis and forming a closed relationship with the first cutting-piercing element, the first laterally-oriented position of the second cutting-piercing element enabling a thrusting and cutting of the pike pole through a building structure followed by a rotating and removal of the pike pole in order to remove portions of the building structure using the edge of the cutting member, and the second longitudinally-oriented position of the second cutting-piercing element facilitating an extraction of the pike pole from the building structure in response to the edge of the cutting member preventing the removal of the pike pole from the building structure when the cutting member is in the first laterally-oriented position; and a controlling system coupled to the handle and actuating the second cutting-piercing element between the first laterally-oriented position and in the opened relationship with the first cutting-piercing element, and the second longitudinally-oriented position and in the closed relationship with the first cutting-piercing element.
