Patent number: 11766803Abstract: A positioner positions a guide ruler relative to a workpiece that is adjacent to the guide ruler while more stably retaining the guide ruler at the locked position without causing interference with a cutting operation. A positioner that positions a ruler body relative to a workpiece includes a contact member to be in contact with an edge of the workpiece and extendable along the edge of the workpiece, a support supporting the contact member in a manner rotatable on a lower surface of the ruler body, and a position retainer that retains the contact member at a rotational position.Type: GrantFiled: July 9, 2020Date of Patent: September 26, 2023Assignee: MAKITA CORPORATIONInventors: Toshiyuki Kani, Hiromu Goto

Patent number: 11364652Abstract: An operation member has a higher degree of design freedom in, for example, the position and the amount of displacement of an operation part, and the force used for operation. A portable cutting machine includes a base, an electric motor, a blade rotatable by the electric motor, a movable cover covering a lower part of the blade protruding downward from the base and rotatable to be open, an operation lever located frontward from a rotation center of the blade and rotatable, and a transmission lever rotatable to push and open the movable cover when pushed by the operation lever.Type: GrantFiled: July 24, 2020Date of Patent: June 21, 2022Assignee: MAKITA CORPORATIONInventors: Toshiyuki Kani, Hiromu Goto

Patent number: 11331732Abstract: Twisting of a locking member due to cogging torque is reduced without lowering the locking and unlocking operability for a user. A power tool includes a housing, an electric motor located inside the housing and including a permanent magnet, a shaft rotatable about an axis relative to the housing to transmit power from the electric motor, a locking member movable between a lock position and an unlock position in a nonenergized state of the electric motor and engageable with the shaft at the lock position to lock rotation of the shaft, and an abutting member that applies, to the locking member at the lock position, a force in a direction opposite to an axial torque caused by the permanent magnet and applied to the locking member.Type: GrantFiled: April 20, 2020Date of Patent: May 17, 2022Assignee: MAKITA CORPORATIONInventors: Toshiyuki Kani, Hiromu Goto, Kenji Hamada, Masaki Murakami

Patent number: 10766162Abstract: When the protruding length of a cutting blade 11 protruding below a lower surface of a base 2 of a portable machining device 1 is set to its maximum length, at least a part of a controller 31 for controlling an electric motor 12 is configured to be located behind a handle 14 in the front-to-rear direction. Furthermore, the controller 31 is disposed so as to be tilted in the left-to-right direction or in the up-to-down direction with respect to the cutting blade 11. Because of this configuration, the height of the handle 14 can be restricted and at the same time the controller 31 can be disposed in a compact manner.Type: GrantFiled: March 14, 2018Date of Patent: September 8, 2020Assignee: MAKITA CORPORATIONInventors: Hiromu Goto, Yuki Wada

Publication number: 20200086405Abstract: A communication adapter 31 for conducting radio communication between a portable machining device 1 and a dust collector 40, such that the dust collector 40 may operate synchronously with the portable machining device 1 with respect to a start/stop operation when performing a cutting task is detachably incorporated in a handle 20 of the portable machining device 1. Because of this arrangement, a high level of dust-proof ability as well as ease of maneuverability in attaching and detaching the communication adapter 31 can be achieved.Type: ApplicationFiled: November 20, 2019Publication date: March 19, 2020Applicant: MAKITA CORPORATIONInventors: Yohei OGINO, Katsumi OKOUCHI, Hiromu GOTO, Yuki WADA
