Patent number: 7325711Abstract: A drive-in tool drives in fastening elements and includes a driving ram and a drive unit. The driving ram is displaceably supported in a guide. The drive unit has a drive flywheel and a return device. The drive flywheel is set in rotation by an electric motor, and the return device displaces the driving ram from an initial position after the completion of the drive-in process. The return device has a return motor separate from the electric motor, and the return motor is connected to the driving ram by a return mechanism.Type: GrantFiled: April 11, 2006Date of Patent: February 5, 2008Assignee: Hilti AktiengeseleschaftInventors: Ulrich Schiestl, Peter Stauss

Patent number: 7322506Abstract: A tool with a driver, which is translatable along a driver axis, and a motor assembly having an electric motor, a flywheel, a roller and an actuator. The electric motor is selectively operable for driving the flywheel. The actuator is selectively operable for translating the roller such that the roller drives the driver against the flywheel to permit energy to be transmitted from the flywheel to the driver. The electric motor is selected to substantially minimize energy losses associated with bringing a mechanical inertial of the motor assembly to a predetermined rotational speed while substantially minimizing an amount of time that is needed to bring the mechanical inertia to the predetermined rotational speed.Type: GrantFiled: March 31, 2005Date of Patent: January 29, 2008Assignee: Black & Decker Inc.Inventor: Michael Forster

Patent number: 7201303Abstract: The present invention teaches a unique drive mechanism for use in a hand held fastener driving tool. The driving mechanism comprises a pair of opposing cams coaxially positioned upon a common shaft. One of the cams is motor driven and rotatable about the common shaft but not axially translatable while the other cam is axially translatable but non-rotatable. Rotation of the rotatable cam by the motor causes the non-rotatable axially translatable cam to compress a compressible spring assembly, storing potential energy therein. Simultaneously, a driver activation cable, wrapped about the rotatable cam's periphery, unwraps thereby raising a fastener driver to its driving configuration. Upon release of the rotatable cam from the motor drive, the potential energy stored within the spring assembly causes reverse rotation of the rotatable cam thereby rewinding the drive cable about the rotatable cam's periphery and driving the fastener driver, whereby the driver drives a fastener into a workpiece.Type: GrantFiled: April 28, 2005Date of Patent: April 10, 2007Assignee: Senco Products, Inc.Inventor: Richard L. Leimbach

Patent number: 7137541Abstract: A fastening tool having a contact trip switch, a trigger switch, a driver, a motor assembly and a controller. The controller is configured to selectively operate the motor assembly in response to inputs received from the contact trip switch and the trigger switch. The controller includes a mode selector switch having a first switch setting, which can permit bump-feed operation of the fastening tool, and a second switch setting, which prohibits bump-feed operation of the fastening tool.Type: GrantFiled: March 31, 2005Date of Patent: November 21, 2006Assignee: Black & Decker Inc.Inventors: Ashok S. Baskar, Craig A. Schell, Alan Berry, Nathan Cruise, Charles L. Bradenbaugh, IV

Patent number: 6863204Abstract: A hammer-type stapler with cartridge is a tool using in building working for driving staples into a working object, comprising a casing having a hollow hammer casing on the front portion of the casing for containing a driving unit. The driving unit moves vertically by inertia force and having a driving element for driving staples, and an elastic element for recoiling the driving unit. A replaceable cartridge is installed in the casing and adjacent to the driving element having two identical, upper and lower staple containers. A pushing device is slidably mounted in the casing for holding the cartridge and pushing staples. The cartridge can load different size staples.Type: GrantFiled: February 9, 2004Date of Patent: March 8, 2005Inventor: Chun-Ming Lu

Patent number: RE43041Abstract: A control module advantageously reduces cost and enhances reliability, design flexibility, ease of assembly, and performance of a flywheel operated hand tool. The control module includes a thin film printed circuit with non-contact speed sensing of a flywheel to more accurately set the target speed and control transfer kinetic energy thereof to a fastener, achieving a desired depth regardless of variations in component performance and battery voltage. The printed circuit also includes long service life thin film switches for responding to trigger and safety inputs. Furthermore, the control module responds to a user speed selection and to preset speed selection ranges to reconfigure the controls as appropriate to constraints of a fastener drive assembly and to user preferences.Type: GrantFiled: December 13, 2007Date of Patent: December 27, 2011Assignee: Senco Brands, Inc.Inventors: Shane Adams, Conrad Garvis, Richard Louis Leimbach
