Publication number: 20170057070Abstract: An improved tool for installing an explosively driven fastener as well as an improved explosively driven fastener for use therewith are disclosed. The fastener includes a nail having a head with an explosive load attached thereto in a plastic cap that includes a buffer. The tool has a plurality of concentric cylinders and springs including a muzzle for receiving the fastener head and explosive load. A spring actuated firing pin ignites the load causing it to explode and drive the nail out of the tool. The explosion also automatically resets the tool. The tool and the fastener provide many advantages over existing explosively driven fasteners and the tools used to install them.Type: ApplicationFiled: November 15, 2016Publication date: March 2, 2017Inventors: Fernando Masas, Joe Lin

Publication number: 20170057071Abstract: A hammer tacker includes an outer housing comprising a handle portion and a head portion, the outer housing formed from a fiber reinforced polymer material. The hammer tacker also includes an elongated staple holder carried at least partially within the outer housing, the elongated staple holder being slideable between a use position and a refill position. The outer housing having the fiber reinforced polymer material defines a channel extending through the handle portion and into the head portion, the channel configured to receive the staple holder. The staple holder is slidable along the channel of the outer housing between the use position and the refill position. The hammer tacker further includes a staple driver assembly operable to drive a staple from the staple holder into a workpiece.Type: ApplicationFiled: August 11, 2016Publication date: March 2, 2017Inventors: Thomas PELLETIER, Kun-Ta WU

Publication number: 20170057073Abstract: A tool socket 2 for a hand-held power tool has a tubular main body 17 and a dust cap 27. The main body 17 has an end face 19 that is adjoined by a cylindrical or prismatic outer surface 36. As seen in the insertion direction 20, the dust cap 27 consecutively has a sealing ring 28, a middle section 29 and a seat 30. As seen in the insertion direction 20, the sealing ring 28 is arranged in front of the end face 19 of the main body 17. The seat 30 has a cylindrical or prismatic inner surface 35 that is in contact with the outer surface 36 of the main body 17. The middle section 29 has a conical inner surface 39 whose inner diameter 40 decreases in the insertion direction 20 down to the inner diameter 37 of the seat 30.Type: ApplicationFiled: February 10, 2015Publication date: March 2, 2017Inventors: Ralf Meixner, Udo Hauptmann

Publication number: 20170057076Abstract: A pneumatic tool includes a main body unit, a control valve unit, a switch unit and a trigger unit. The main body unit has a flow path for guiding inflow of air. The control valve unit removably blocks the flow path. The switch unit includes a sleeve member movable between an open position where the control valve unit is driven to unblock the flow path, and a block position where the control valve unit is driven to block the flow path. The trigger unit includes a trigger member operable to move the sleeve member between the open position and the block position.Type: ApplicationFiled: August 23, 2016Publication date: March 2, 2017Inventor: San-Yih Su
