Problems solved by technology

Both of these techniques typically take hours to blast through thick reinforced concrete walls, and the equipment is not portable in some cases
The army also uses explosives to quickly blast walls, but this is dangerous for the victim and can shake structures
Lasers are also used in blasting applications, but size, safety, and power limitations often make lasers unfeasible

Embodiment Construction

[0015] refer to figure 1 , provides a controlled impact rescue tool (CIRT) 10 . CIRT 10 is described in detail in US Patent No. 7,814,822, which is hereby incorporated by reference in its entirety. In general, the CIRT 10 includes a housing 20 , an ignition mechanism 30 and a single body percussion element 40 . A housing 20 is formed to define a passage 21 and includes a piston head 22 and a biasing unit 23 . Piston head 22 is movable through passage 21 between a loading position, in which piston head 22 is ready to fire, and a firing position, in which piston head 22 has undergone selective firing operation and subsequent impact. The biasing unit 23 is configured to bias the piston head 22 to remain in the charged position until selective ignition operation. The biasing unit 23 may include an elastic element, such as a spring, and may further include a temporary lock engageable with the piston head 22 disposed in the loading position, thereby preventing the piston head 22 ...

Abstract

An impact element is provided and includes a single body drivable into an external element by force acting on a piston head. The single body includes a head and a shaft having a first end integrally coupled to the head, a second end opposite the first end and a central portion interposed between the first and second ends. The second end of the shaft is operatively connectable with the piston head to define a joint located remotely from the head. The first end of the shaft has a trailing portion with a diameter similar to that of the central portion, a leading portion with a diameter similar to that of the rear end of the head and a taper from the trailing portion to the leading portion.

Description

technical field [0001] The subject matter disclosed herein relates to an impact element, and more particularly, to an impact element for a controlled impact rescue tool (CIRT). Background technique [0002] Urban search and rescue teams often need to create openings (called "gaps") in rigid structures, such as reinforced concrete walls, to reach victims inside buildings after a disaster, such as an earthquake or hurricane. To facilitate search and rescue operations, blasting equipment should be portable, easy to operate, and fast and effective without destabilizing structures or threatening to injure operators or victims. [0003] Techniques for blasting concrete walls typically include gasoline and hydraulic powered diamond chainsaws, gasoline and hydraulic powered circular saws, diamond wire saws, large drills, hydraulic / pneumatic / electric impact tools, water jets, and hydraulic splitters. Both of these techniques typically require several hours to blast thick reinforced ...
