Hammer drill adaptors and methods of use

A method of using a hammer drill adaptor to install a drive cleat to join air ducts comprising the steps of:

• obtaining adjacent air ducts;
• obtaining a drive cleat operable to join said adjacent air ducts;
• obtaining a hammer drill having a hammer drill chuck;
• obtaining a hammer drill adapter having a shaft portion and a first portion wherein said shaft portion extends proximally from a proximal end of said first portion and wherein said first portion has a rectangular shaped capture cavity extending proximally from a secondary surface of said hammer drill adaptor and wherein said capture cavity terminates at a distally facing rear surface, and wherein a tongue portion of said first portion extends distally from one side of the rectangular shaped capture cavity and terminates at a distally facing entry surface;
• securing a portion of said shaft portion of the hammer drill adapter in the hammer drill chuck;
• inserting one end of said drive cleat into said capture cavity until a terminal end of the drive cleat abuts said rear surface of said drive cleat at a proximal end of said capture cavity;
• positioning the hammer drill with drive cleat seated in the capture cavity to a seam of adjacent air ducts;
• joining the leading end of the drive cleat to the seam of the adjacent air ducts;
• actuating the hammer drill to exert a plurality of pulses to said rear surface of said hammer drill adapter thereby driving said drive cleat into an installed position wherein said adjacent air ducts are joined together by said drive cleat;
• and
• removing said hammer drill and said hammer drill adapter from said drive cleat.

A hammer drill adapter for driving a drive cleat to join air ducts comprising:

• a first portion of said hammer drill adapter aligned in a plane;
• a shaft portion of said hammer drill adapter having an elongate axis parallel to said plane;
• said first portion fixed to said shaft portion;
• said shaft portion extending proximally from a proximal end of said first portion;
• a distally facing entry surface at a distal end of said first portion;
• a distally facing secondary surface positioned proximal from said entry surface;
• a rectangular capture cavity extending proximally through said entry surface into said first portion;
• said capture cavity defined proximally by a distal facing rear surface;
• said capture cavity defined by an opposed lower capture surface and an upper capture surface;
• said lower capture surface spaced from said upper capture surface;
• said capture cavity laterally defined by an opposed first capture surface and a second capture surface;
• said first capture surface spaced from said second capture surface;
• said capture cavity sized to house an entire end portion of a drive cleat therein;
• said shaft portion comprising a first connection portion at a proximal end comprising an indentation of the shaft surface;
• said indentation having an enclosed first end and enclosed second end for fixation within a hammer drill chuck;
• an elongate slot generally parallel to said elongate axis;
• said elongate slot extending from said entry surface to said rear surface;
• said elongate slot extending between said upper capture surface of said capture cavity and an upper surface on outside of said first portion.
