20100038394 | Cordless Nailer Drive Mechanism Sensor - A device for impacting a fastener in one embodiment includes a lever arm pivotable between a first position whereat a flywheel is spaced apart from a drive mechanism and a second position whereat the flywheel can contact the drive mechanism, a lever arm solenoid for pivoting the lever arm between the first position and the second position, a drive mechanism sensor for generating a position signal indicative of the position of the drive mechanism, a timer for generating a timing signal, a memory including program instructions, and a processor operably connected to the memory for executing the program instructions to (i) energize the solenoid to pivot the lever arm to the second position, (ii) de-energize the solenoid based upon the position signal, and (iii) de-energize the solenoid based upon the timing signal. | 02-18-2010 |
20100038395 | Cordless Nailer With Safety Sensor - A device for impacting a fastener in one embodiment includes a lever arm pivotable between a first position whereat a flywheel is spaced apart from a drive mechanism and a second position whereat the flywheel can contact the drive mechanism, a motor operably connected to the flywheel for storing energy in the flywheel, a trigger sensor assembly for generating a trigger signal indicative of the position of a trigger, a work contact element (WCE) sensor for generating a WCE signal indicative of the position of a WCE, a memory including program instructions, and a processor operably connected to the memory for executing the program instructions to (i) energize the motor based upon the WCE signal, and (ii) pivot the lever arm based upon the trigger signal. | 02-18-2010 |
20100038396 | Cordless Nail Gun - A device for impacting a fastener in one embodiment includes a frame, a motor mounted to the frame and including a drive shaft defining a drive shaft axis, a lever arm including a pivot axis parallel with the drive shaft axis, a flywheel rotatably mounted on the lever arm and operably connected to the motor for storing energy received from the motor, a drive mechanism for impacting a fastener, and a solenoid configured to pivot the lever arm between a first position wherein the flywheel is spaced apart from the drive mechanism and a second position wherein the flywheel can contact the drive mechanism. | 02-18-2010 |
20100038397 | Cordless Nailer With Safety Mechanism - A device for impacting a fastener in one embodiment includes a drive mechanism, a flywheel pivotable between a first flywheel position whereat the flywheel is not in contact with the drive mechanism and a second flywheel position whereat the flywheel contacts the drive mechanism, a motor operably connected to the flywheel, a trigger movable between a first trigger position and a second trigger position, and a WCE assembly movable between a first WCE position and a second WCE position, the WCE assembly configured such that (i) when the trigger is in the first trigger position and the WCE assembly is in the first WCE position, the WCE assembly mechanically engages the trigger to preclude movement of the trigger out of the first position, and (ii) when the WCE assembly is in the second WCE assembly position, the WCE assembly does not mechanically engage the trigger. | 02-18-2010 |
20100213232 | NAILER WITH BRUSHLESS DC MOTOR - A device for impacting a fastener in one embodiment includes a drive mechanism configured to impact a fastener, a lever arm pivotable between a first position and a second position, and a motor including a plurality of permanent magnets mounted on a rotatable housing, the motor mounted on the lever arm such that when the lever arm is in the first position, the rotatable motor housing is isolated from the drive mechanism and when the lever arm is in the second position, the rotatable motor housing is positioned to transfer rotational energy to the drive mechanism. | 08-26-2010 |
20110132959 | FASTENER DRIVER WITH AN OPERATING SWITCH - A fastening tool includes a drive assembly configured to drive a fastener from the fastening tool, a work contact element moveable between an extended position and a depressed position, a trigger moveable between a release position and a fire position, an electric power source, an electronic control unit configured to deliver electric power from the electric power source to the drive assembly, and a single electric switch connected to the electronic control unit and configured to indicate that the work contact element is in the depressed position and the trigger is in the fire position. | 06-09-2011 |
20140160729 | CIRCULAR SAW WITH LIGHT EMITTING ELEMENT SYSTEM - A power tool includes a working element, a motor, a motor actuator, a housing, a light emitting element, a locking element, and a switch element positioned between the housing and the locking element. The housing supports the motor, the motor actuator, and the light emitting element and movably supports the locking element. The light emitting element illuminates a work area around the working element, and the motor drives the working element when actuated by the motor actuator. The locking element enables operation of the motor actuator when in an unlocked position and prevents operation of the motor actuator when in a locked position. When in the unlocked position, the locking element operates the switch element to activate the light emitting element. | 06-12-2014 |
