Multistage solenoid fastening device
First Claim
Patent Images
1. A device for inserting one or more fasteners into a workpiece, the device comprising:
- a tool housing having a trigger assembly that activates a driver sequence;
a multistage solenoid in said tool housing having at least a first stage, a second stage, and an armature member with a driver blade member that travels between said first stage and said second stage; and
a control module in said tool housing that connects said trigger assembly to said multistage solenoid, said control module determines a position of said armature member relative to at least said first stage and said second stage and directs power between at least said first stage and said second stage based on said position of said armature member relative to at least said first stage and said second stage during said driver sequence.

Abstract
A device that generally includes a multistage solenoid having at least a first stage, a second stage and an armature member that travels therebetween. The device also includes a control module connected to the multistage solenoid. The control module detects a position of the armature member relative to at least one of the first stage, the second stage and a combination thereof. The control module adjusts a magnetic field of the at least one of the first stage, the second stage and the combination thereof based on the position of the plunger armature relative thereto.

8. A hand-held device for inserting one or more fasteners into a workpiece, the hand-held device comprising:
-
a multistage solenoid having at least a first stage, a second stage, and an armature member that travels between said first stage and said second stage; and a control module connected to said multistage solenoid that detects a position of said armature member relative to at least said first stage and said second stage by determining a change in a rate of current caused by a change in an inductance of a circuit associated with one of said first stage and said second stage, wherein said control module adjusts a magnetic field of at least one of said first stage and said second stage based on said position of said armature member relative to said first stage and said second stage. - View Dependent Claims (9)

10. A device for inserting one or more fasteners into a workpiece, the device comprising:
-
a housing; a multistage solenoid in said housing having an armature member that travels between at least a first stage and a second stage; and a control module connected to said multistage solenoid, said control module detects a position of said armature member relative to at least one of said first stage, said second stage, and a combination thereof, said control module adjusts a magnetic field of said at least one of said first stage, said second stage, and said combination thereof based on said position of said armature member; and a trigger assembly connected to said control module to execute a driver sequence that causes said armature member to travel between at least the first stage and the second stage. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
