Patent number: 12122016Abstract: A long rod grinding machine reduces the likelihood of dust escaping and falling. The long rod grinding machine includes a head and a rod having an end connected to the head and extending in a front-rear direction. The head includes an electric motor, a pad movable with a driving force from the electric motor, a vertical wall surrounding a radially outer edge of the pad, and a contact member located between the vertical wall and the pad and surrounding the radially outer edge of the pad. The contact member includes a brush holder having one or more through-holes extending in a radial direction of the pad, and a brush located below the brush holder and having a lower end located downward from a lower end of the vertical wall.Type: GrantFiled: February 8, 2022Date of Patent: October 22, 2024Assignee: MAKITA CORPORATIONInventor: Fumihide Sugita

Publication number: 20240278370Abstract: A dust bag includes a frame disposed inside the bag main body. The frame includes at least one non-flexible portion extending in the first direction and/or a second direction perpendicular to the first direction so as not to have flexibility in the first direction, and at least one flexible portion coupled with the at least one non-flexible portion and extending in an intersection direction intersecting with the first direction and the second direction so as to have flexibility in the first direction. The frame is configured to be extensible and compressive in the first direction due to the at least one flexible portion deflected when an external force is applied in the first direction. A total width of the at least one flexible portion in the first direction is equal to or wider than a total width of the at least one non-flexible portion in the first direction.Type: ApplicationFiled: January 31, 2024Publication date: August 22, 2024Applicant: Makita CorporationInventor: Fumihide Sugita

Publication number: 20240157506Abstract: A portable abrading machine includes an abrading-machine main body, a battery holster, and a power-supply cord. The abrading-machine main body includes a main-body housing, which houses a motor, and an abrading part, which is configured to move with orbital motion when a motor shaft of the motor is rotated. The battery holster includes a battery-mounting part, on which a battery is mountable. The power-supply cord is configured to supply electric power from the battery, when mounted on the battery-mounting part, to the abrading-machine main body. The power-supply cord connects the abrading-machine main body and the battery holster without going through the housing.Type: ApplicationFiled: January 13, 2022Publication date: May 16, 2024Inventor: Fumihide Sugita

Publication number: 20240157499Abstract: A long rod polishing device includes a prismatic or columnar battery, a battery mounting portion, an electric motor, a pad, and a rod portion. The battery is mountable to the battery mounting portion. The electric motor is driven by an electric power from the battery. The pad has a polishing surface and moves by a driving force from the electric motor. The rod portion has an end portion to which the pad is coupled. The battery mounted to the battery mounting portion has a longest side. The longest side has a direction so as to form an angle with respect to a second imaginary straight line. The second imaginary straight line is perpendicular to both of a center axis of the rod portion and a first imaginary straight line. The first imaginary straight line is perpendicular to the center axis and parallel to the polishing surface of the pad.Type: ApplicationFiled: January 19, 2024Publication date: May 16, 2024Applicant: MAKITA CORPORATIONInventor: Fumihide SUGITA
