Contact trip mechanism for nailer
A contact trip assembly for a power nailer, wherein a contact member includes a curved portion that loops rearwardly towards a handle of the nailer. Also provided is an adjustment assembly including an adjustment plate and a pinion gear, a trigger that is slidably engageable within a housing of the tool, a trigger lock including a ring element, an anti-discharge mechanism including a stop member, and a contact trip lock.
1. A contact trip adjustment assembly for a power nailer comprising:
a slider plate;
an adjustment plate mounted to said slider plate, said adjustment plate including a first slot and a second slot, each slot having a plurality of positions;
a contact trip member that engages first slot of said adjustment plate, wherein said contact trip member moves through said plurality of positions of said first slot to adjust a depth of said contact trip member; and
a switch member adapted to contact a switch, said switch member engaged with said second slot of said adjustment plate.
2. The adjustment assembly according to claim 1 , wherein said plurality of positions of said slot are in a stepped orientation.
3. A contact trip adjustment assembly for a power nailer comprising:
a slider plate;
an adjustment plate including a slot with a plurality of positions, said adjustment plate slidably mounted to said slider plate;
a contact trip member that engages said slot of said adjustment plate; and
a pinion gear engageable with a plurality of teeth formed on an edge of said slider plate,
wherein said contact trip member moves through said plurality of positions of said slot to adjust a depth of said contact trip member.
4. The adjustment assembly according to claim 3 , further comprising a J-shaped flange supported by said pinion gear.
5. The adjustment assembly according to claim 4 , wherein the J-shaped flange and said pinion gear are a unitary piece.
6. The adjustment assembly according to claim 4 , wherein said J-shaped flange and said pinion gear are coupled to a dial knob.
7. The adjustment assembly according to claim 3 , further comprising a knob attached to said pinion gear.
8. The adjustment assembly according to claim 7 , wherein said knob extends from a housing of the power nailer.
9. The adjustment assembly according to claim 7 , wherein said knob includes indicia thereon indicative of a position of said contact trip member.
10. A contact trip adjustment assembly for a power nailer comprising:
a slider plate;
an adjustment plate including a slot with a plurality of positions, said adjustment plate slidably mounted to said slider plate;
a contact trip member that engages said slot of said adjustment plate, wherein said contact trip member moves through said plurality of positions of said slot to adjust a depth of said contact trip member; and
said slider plate moves linearly in a first direction relative to a base structure of the power nailer, and said adjustment plate moves in a second direction transverse to said first direction, the motion of said adjustment plate in said second direction being controlled by movement of said contact trip member through said plurality of positions of said slot and a compression of said contract trip member against a workpiece.
