Abstract
The fastener tool includes a nosepiece, a nosepiece cover pivotally attached to the nosepiece, a latch pivotally attached to the nosepiece cover, a latch wire pivotally attached to the latch for engaging at least one hook disposed on the nosepiece, wherein the latch wire has a portion extending between the latch and the hook, the portion having at least two bends.
Claims32
A fastener tool comprising:
- a housing comprising a nosepiece;
- a magazine connected to the housing for storing a fastener;
- a driving mechanism disposed within the housing for driving the fastener into a workpiece;
- a trigger assembly pivotally attached to the housing for activating the driving mechanism;
- a nosepiece cover pivotaly attached to the nosepiece;
- a latch pivotally attached to the nosepiece cover;
- and
- a latch wire pivotally attached to the latch for engaging at least one hook disposed on the nosepiece;
- wherein the latch wire has a portion extending between the latch and the hook, the portion having at least two bends.
6 more elements
A fastener tool comprising:
- a housing;
- a magazine connected to the housing for storing a fastener;
- a driving mechanism disposed within the housing for driving the fastener into a workpiece;
- a trigger assembly pivotally attached to the housing for activating the driving mechanism;
- and
- a trigger lock disposed between the housing and the trigger assembly, the trigger lock being movable between a first position limiting the pivoting range of the trigger assembly relative to the housing for preventing the trigger assembly from activating the driving mechanism, and a second position not preventing the trigger assembly from activating the driving mechanism position.

A fastener tool comprising:
- a housing comprising a nosepiece;
- a magazine connected to the housing for storing a fastener;
- a driving mechanism disposed within the housing for driving the fastener into a workpiece;
- a trigger assembly pivotally attached to the housing for activating the driving mechanism;
- and
- a nosepiece cover pivotally attached to the nosepiece;
- wherein one of the nosepiece and the nosepiece cover have a protrusion contacting the other of the nosepiece and the nosepiece cover upon rotation of the nosepiece cover for limiting rotational motion range of the nosepiece cover relative to the nosepiece.
