Patent ID: 7628383

Claim:
A method of operating a rachet strap tightener using a power driven rotary tool, the rachet strap tightener comprising a tightener body, a spindle rotatably supported about a spindle axis relative to the tightener body for winding a first strap thereon in first direction, a first mating part rotatable with the spindle relative to the tightener body and a ratcheting mechanism arranged to selectively restrict rotation of the spindle relative to the tightener body in an opposing second direction, the tightener body comprising a pair of side plates oriented perpendicularly to the spindle axis and spaced apart from one another along the spindle axis, the power driven rotary tool comprising a tool body, a second mating part arranged to mate with the first mating part of the rachet strap tightener and arranged to be driven to rotate about a drive axis, the method comprising: providing an aperture in each of the side plates such that the apertures are aligned with one another along a receptacle axis which is parallel and spaced from the spindle axis so as to slidably receive a portion of the tool body therein; anchoring the tool body relative to the tightener body by slidably receiving said portion of the tool body into the apertures in each of the side plates; mating the second mating part of the rotary driven tool with the first mating part of the rachet strap tightener; and driving the second mating part of the rotary driven tool to rotate the spindle of the rachet strap tightener.
