Abstract:
1. A fastening element feeding device for a power drive-in tool, comprising a first component ( 11 ) connectable with the power drive-in tool ( 80 ); and a second component ( 21 ) displaceably supported on the first component ( 11 ) and having a head ( 22 ) placeable on a constructional component (U), and a transportation device ( 30 ) for feeding fastening elements ( 51 ) arranged in a magazine strip ( 50 ) in a drive-in channel ( 12 ), the transportation device ( 30 ) including a transportation wheel ( 32 ) for the magazine strip ( 50 ) and rotatably supported on a rotary axle (D), at least one actuation member ( 35 ) displaceable in a control track ( 16 ) in a first component ( 11 ) for effecting a relative displacement between the first component ( 11 ) and the second component ( 21 ) which results in a transportation displacement of the transportation wheel ( 32 ); a displacing member ( 31 ) having one end region ( 39 ) thereof, which is adjacent to the head ( 22 ), supporting the rotary axle (D) together with the transportation wheel ( 32 ) and having another end region ( 38 ) thereof supporting the at least one actuation member ( 35 ); and guide means providing for displacement of the displacing member ( 31 ) over the second component ( 21 ), wherein the guide means comprises at least one first guide curve ( 26 ) and at least one second guide curve ( 27 ) provided on the second component ( 21 ), a first control pin ( 36 ) provided on the displacing member ( 31 ) and displaceable along the first guide curve ( 26 ) for converting a relative movement between the first component ( 11 ) and the second component ( 21 ) into a relative movement between the displacing member ( 31 ) and the second component ( 21 ), and a second control pin ( 37 ) provided on the displacing member ( 31 ) and displaceable along the second guide curve ( 27 ) for converting a relative movement between the displacing member ( 31 ) and the second component ( 21 ) into a transportation displacement of the transportation wheel ( 32 ).
