Abstract
A chiropractic adjustment tool or tapper comprises a housing, the housing having an open end; a impact assembly disposed within the housing and secured thereto. The impact assembly comprises a reciprocating rod with adjustable travel and impact force. An impelling element such as a solenoid is provided to accelerate the reciprocating rod. Disposed on one end of the reciprocating rod is a coupler to permit multiple impact heads to be attached to the tool. The tool is further improved with the addition of a fan unit on a port in the housing and an exit port located on a distal end of the housing, preferably at a location such that air flow is across the impelling element, and any switch or circuitry to provide cooling and extend tool life.
Claims3
An impact tool comprising:
- a housing containing a impact assembly,
- said impact assembly comprising:
- an axially reciprocating rod, said reciprocating rod operatively connected to an impelling means, said reciprocating rod having disposed on one end a coupler for adjustably affixing a one or more impact heads at one or more angles of impact,
- wherein said coupler is comprised of:
- a collar affixed to said reciprocating rod proximate a forward end of said reciprocating rod, said collar set with a collar pin,
- a sleeve element disposed within said one or more impact heads for insertably receiving said forward end of said reciprocating rod,
- a sleeve base affixed to said sleeve element to abut said collar,
- an at least one pin notch placed in said sleeve base for receiving said collar pin,
- a means to removably secure said one or more impact heads to said reciprocating rod.
An impact tool, comprising:
- a housing with an inner surface and an outer surface,
- an impact assembly disposed within said housing, said impact assembly being operatively connected to a power source, with said impact assembly comprising a reciprocating rod transiting said housing with an adjustable stop and an impelling means operatively connected to said reciprocating rod,
- and a coil spring pair,
- wherein said coil spring pair is comprised of a forward spring disposed around said reciprocating rod and a rearward spring disposed around said reciprocating rod,
- said forward spring being biased against said adjustable stop and against the inner surface of the housing on the rearward side,
- said rearward spring biased against the outer surface of the housing and fitted against a threaded annular head, said threaded annular head being affixed to said reciprocating rod.
