Patent ID: 7303105

Claim:
A nailing device for securing hardwood flooring planks to a subfloor using arcuate fasteners, said nailing device comprising: a main body defining a fastener discharge opening; a fastener ejection channel made in said main body, said fastener ejection channel being arcuate and for accommodating an arcuate fastener, said fastener ejection channel opening outwardly of said nailing device at said fastener discharge opening; a plunger at least partially nested in said fastener ejection channel, said plunger movable along said fastener ejection channel between first and second limit positions; and a plunger actuator nested in said main body and connected to said plunger, wherein said plunger actuator can be selectively activated for moving said plunger between its said first and second limit positions; wherein upon activation of said plunger actuator, said plunger will move along said fastener ejection channel from said first limit position towards said second limit position to forcibly strike the arcuate fastener located in said fastener ejection channel and eject it out of said nailing device through said fastener discharge opening and into a subjacent workpiece; wherein said plunger actuator comprises at least one driving arm pivotally connected to said main body at one end and carrying said plunger at the other end, whereby said plunger is movable between its said first and second limit positions upon said driving arm being pivotally actuated; and wherein said plunger actuator further comprises a rectilinearly movable member capable of moving rectilinearly within said main body between first and second limit positions, said plunger actuator further comprising at least one cam member pivotally connected to said rectilinearly movable member at one end and to said driving arm at the other end, wherein upon selective activation of said plunger actuator, said rectilinearly movable member is actuated from its said first limit position towards its said second limit position, and said driving arm is concomitantly pivotally actuated such that said plunger moves from said first limit position towards said second limit position.
