Publication number: 20190091847Abstract: An apparatus and method is provided for holding fasteners (such as lag screws) while being driven into a work piece. The holder holds the fastener away from a worker's hand so that it may be driven into the work piece without the hand being close to the driving action of the driving tool (such as a hammer). The holder then releases the screw to be completely driven into the work piece. While the fastener is being set, the holder holds one or more other fasteners in reserve.Type: ApplicationFiled: November 28, 2018Publication date: March 28, 2019Inventor: Timothy R. Sook

Publication number: 20190091848Abstract: A hand-held machine tool, in particular a sanding machine, including a rod-type handle element for the user to grip and a processing head which is moveably mounted on the handle element by means of a joint assembly. The processing head has an electric drive motor for driving a tool holder provided for holding a processing tool and a speed-reducing gearbox between the drive motor and the tool holder, the gearbox being designed to achieve a reduction in speed of an output of the drive motor relative to a speed of the tool holder. The drive motor is a brushless motor and a power supply system for the drive motor is arranged at a distance from the drive motor on the handle element, the power supply system being connected to the drive motor by means of a cable arrangement.Type: ApplicationFiled: April 10, 2017Publication date: March 28, 2019Applicant: Festool GmbHInventor: Nico Walker

Publication number: 20190091850Abstract: A tool grip is provided, includes a grip portion, a metal base, and a coating. The metal base is disposed on the grip portion, the metal base includes a hole for receiving a drive rod and a plurality of rib portions extending radially outwardly relative to the hole. Each of the plurality of rib portions includes a bridge section and a grip plate. The bridge section extending radially is connected with the grip plate and located between the hole and the grip plate. The grip plate is greater than the bridge section in circumferential size. The coating covers the metal base. At least part of the coating is disposed in a recess between adjacent two of the rib portions. At least part of each of the grip plate is exposed radially relative to the coating.Type: ApplicationFiled: September 28, 2017Publication date: March 28, 2019Inventor: Yu-Hua OU

Publication number: 20190091851Abstract: A mobile robot includes an electric device unit disposed inside a cover and upward of a robot, and a transport mechanism disposed downward of the robot. An end part of a rotation shaft of a motor driving an arm portion of the robot faces downward. The cover includes a partition plate separating a first housing space in which the electric device unit is housed and a second housing space in which the robot is housed. The partition plate has a protrusion protruding into the first housing space. The protrusion provides a motor housing space in the second housing space. At least one part of the first motor is housed in the motor housing space when a base of the robot is elevated to an uppermost position.Type: ApplicationFiled: September 13, 2018Publication date: March 28, 2019Inventors: Yoshinori TAKAHASHI, Shigeru TAKEDA
