Abstract

A powered fastening device is provided and is capable of applying multiple strikes to a fastener to drive the fastener to a preselected depth in a work piece and then automatically stopping the strikes when the preselected depth has been achieved.

First claim

What is claimed is:

1. A powered fastening device comprising:
a main housing;
a fastener drive assembly carried in the main housing to drive a fastener into a work piece along a drive axis;
a drive motor carried in the main housing and operably connected to the fastener drive assembly to actuate the fastener drive assembly;
a feeder assembly configured to carry a plurality of fasteners and to sequentially position each fastener of the plurality of fasteners relative to the fastener drive assembly to be driven by the fastener drive assembly into the work piece, the feeder assembly mounted to the main housing to translate along the drive axis relative to the main housing and the fastener drive assembly between a start position and a stop position as each fastener of the plurality of fasteners is driven into the work piece;
an adjustable depth selector carried between the main housing and the feeder assembly to selectively adjust the location of the stop position along the drive axis to control how deep each fastener of the plurality of fasteners from the feeder assembly can be driven into the work piece by the fastener drive assembly; and
a motor control operably connected to the drive motor, the motor control configured to disable the drive motor in response to the feeder assembly translating to the stop position; and wherein
the motor control comprises a user actuated trigger switch, and the motor control configured to enable the drive motor in response to user actuation of the trigger switch;
the motor control further comprises a mechanically actuated switch, the mechanically actuated switch having an unactuated condition and an actuated condition;
the powered fastening device further comprises a switch-actuating member located to actuate the mechanically actuated switch from one of the actuated and unactuated conditions to the other of the actuated and unactuated conditions with the feeder assembly in the stop position; and
the motor control is configured to enable the drive motor with the mechanically actuated switch in the one of the actuated and unactuated conditions and to disable the drive motor in response to the mechanically actuated switch being maintained in the other of actuated and unactuated conditions for a predetermined time period.

2. The powered fastening device of claim 1 , wherein the mechanically actuated switch is fixed on the feeder assembly, and the switch-actuating member is part of the adjustable depth selector.

3. The powered fastening device of claim 2 , wherein the adjustable depth selector comprises a rotatable selection knob positioned between the feeder assembly and the main housing.

4. The powered fastening device of claim 3 , wherein the rotatable selection knob has a distal end that abuts the feeder assembly with the feeder assembly in the stop position, the distal end comprising the switch-actuating member.

5. The powered fastening device of claim 2 , further comprising an elongate rail extending between the main housing and the feeder assembly to mount the feeder assembly for translation along the drive axis relative to the fastener drive assembly.

6. The powered fastening device of claim 5 , wherein the adjustable depth selector comprises a rotatable selection knob surrounding a portion of the elongate rail between the feeder assembly and the main housing.

7. The powered fastening device of claim 6 , wherein the rotatable selection knob is in threaded engagement with the elongate rail and has a distal end that abuts the feeder assembly with the feeder assembly in the stop position, the distal end comprising the switch actuating member.

8. The powered fastening device of claim 1 , wherein the mechanically actuated switch comprises a switch body and an input member mounted on the switch body to move between an unactuated position and an actuated position, the switch changing from the unactuated condition to the actuated condition in response to the input member moving from the unactuated position to the actuated position.

9. A powered fastening device comprising:
a main housing;
a fastener drive assembly carried in the main housing to drive a fastener into a work piece along a drive axis;
a drive motor carried in the main housing and operably connected to the fastener drive assembly to actuate the fastener drive assembly;
a feeder assembly configured to carry a plurality of fasteners and to sequentially position each fastener of the plurality of fasteners relative to the fastener drive assembly to be driven by the fastener drive assembly into the work piece, the feeder assembly mounted to the main housing to translate along the drive axis relative to the main housing and the fastener drive assembly between a start position and a stop position as each fastener of the plurality of fasteners is driven into the work piece;
an adjustable depth selector carried between the main housing and the feeder assembly to selectively adjust the location of the stop position along the drive axis to control how deep each fastener in the feeder assembly can be driven into the work piece by the fastener drive assembly;
a motor control operably connected to the drive motor, the motor control comprising a mechanically actuated switch, the mechanically actuated switch having an unactuated condition and an actuated condition; and
a switch-actuating member located to actuate the mechanically actuated switch from one of the actuated and unactuated conditions to the other of the actuated and unactuated conditions with the feeder assembly in the stop position;
wherein the motor control is configured to enable the drive motor with the mechanically actuated switch in the one of the actuated and unactuated conditions and to disable the drive motor in response to the mechanically actuated switch being maintained in the other of the actuated and unactuated conditions for a predetermined time period.

10. The powered fastening device of claim 9 , wherein the motor control comprises a user actuated trigger switch, and the motor control is configured to energize the drive motor in response to user actuation of the trigger switch.

11. The powered fastening device of claim 9 , wherein the mechanically actuated switch is fixed on the feeder assembly, and the switch-actuating member is part of the adjustable depth selector.

12. The powered fastening device of claim 11 , wherein the adjustable depth selector comprises a rotatable selection knob positioned between the feeder assembly and the main housing, the rotatable selection knob has a distal end that abuts the feeder assembly with the feeder assembly in the stop position, and the distal end comprises the switch-actuating member.

13. A powered fastening device comprising:
a main housing;
a fastener drive assembly carried in the main housing to drive a fastener into a work piece along a drive axis;
a drive motor carried in the main housing and operably connected to the fastener drive assembly to actuate the fastener drive assembly;
a feeder assembly configured to carry a plurality of fasteners and to sequentially position each fastener of the plurality of fasteners relative to the fastener drive assembly to be driven by the fastener drive assembly into the work piece, the feeder assembly mounted to the main housing to translate along the drive axis relative to the main housing and the fastener drive assembly between a start position and a stop position as each fastener of the plurality of fasteners is driven into the work piece; and
a motor control operably connected to the drive motor, the motor control configured to disable the drive motor in response to the feeder assembly translating to the st
