AN IMPACT TOOL SYSTEM FOR REDUCING SPALLING, VIBRATION, NOISE AND BIOMECHANICAL STRESS

摘要

The inventors have designed a tool 1 to be struck, or a striking tool, with a fiber-reinforced polymeric disc (collectively referred to as an "impact tool"), or alternatively, a ribbed cap with novel material and shape characteristics, that will not suffer metal spall and the attendant dangers from noise and from spalling and flying or cutting metal slivers, i.e. a catastrophic failure of part or all of a tool. By further modifying the working end of the tool, impact effectiveness can be maintained. Other tools such as impact wrenches, impact tools, jackhammers, electric hammers, air hammers, wedges, spikes, hammers, mallets or other tools being struck or striking forcibly benefit from the invention. Also contemplated is a one piece cap with rounded edges and with molded, rounded structural reinforcing ribs.
