Publication number: 20230191509Abstract: A portable cutting apparatus includes a base, a main body and a cover both on a second side of the base. The main body is displaceable relative to the base and the cover between a first position, where a blade is entirely contained in the cover, and a second position, where the blade protrudes to a first side opposite the second side beyond the base. The cover includes a cover main body, and an auxiliary cover located in proximity to the base and movable relative to the cover main body. The main body portion and the cover main body are tiltable about a first axis located on the first side of the base. The auxiliary cover is at least partially tilted about a second axis located on the second side of a surface of the base on the first side in conjunction with the tilting of the cover main body.Type: ApplicationFiled: December 9, 2022Publication date: June 22, 2023Applicant: MAKITA CORPORATIONInventors: Yohei OGINO, Koichi TSUDA

Publication number: 20230191649Abstract: A portable machining apparatus includes a main body, a cover including a cover main body and a door, a door open/close mechanism, and a lock to lock the open/close mechanism in a closed state displaceably supported by the cover main body or the main body portion. The main body is displaceable relative to the cover between a first position entirely containing the tip tool in the cover, and a second position partially exposing the tip tool outside the cover. The lock is manually displaceable between a position blocking the door from opening, and a position permitting the door to open. The lock is displaceable when the main body is at the first position, and is not displaceable by abutment between the other of the cover main body and the main body and the lock operation member when the main body is at a position other than the first position.Type: ApplicationFiled: December 9, 2022Publication date: June 22, 2023Applicant: MAKITA CORPORATIONInventors: Yohei OGINO, Koichi TSUDA

Patent number: 10668644Abstract: The dust proof circular saw has a main body with a rotating disc cutter blade and a cover fixed to the body to cover a blade outer radial periphery part. The body is supported by a base such that an angle of the body in the up-down and right-left directions can be adjusted at a base upper side. A further blade outer radial periphery is covered by an auxiliary cover. The auxiliary cover covers a gap between the fixed cover and the base. The auxiliary cover is moved by a mechanism relative to the body in accordance with an angle of the circular saw main body relative to the base in the up-down direction. The auxiliary cover is pivotally connected to the base, and is pivoted around a laterally tilting support shaft in the right-left direction by an interlock mechanism in accordance with a body angle in the right-left direction.Type: GrantFiled: August 15, 2017Date of Patent: June 2, 2020Assignee: MAKITA CORPORATIONInventors: Katsumi Okouchi, Yohei Ogino

Patent number: 10207399Abstract: An electric tool may include a tubular housing, a motor disposed within the housing, and a tool holder rotatably driven by the motor and capable of holding an end tool. A shoe may be supported by the housing and may determine a protruding length of the end tool from one end of the housing. A battery mount portion may be disposed at the other end of the housing. The battery may be mounted to the battery mount portion as the battery is slid relative to the battery mount portion along a direction intersecting the extending direction of the housing.Type: GrantFiled: April 28, 2017Date of Patent: February 19, 2019Assignee: MAKITA CORPORATIONInventors: Katsumi Okouchi, Yohei Ogino

Patent number: 9527200Abstract: A shoe attached to a shoe attachment portion includes a spanner portion. As the shoe can be separated from a tool main body of the cutout tool, the shoe can be used as a spanner. The shoe can function as the spanner for replacing a bit in a bit attachment mechanism. In addition, the shoe has its original function of the shoe by which a protrusion amount of the bit can be adjusted. Since the shoe is attached to the shoe attachment portion and held by the tool main body, it turns out that the spanner can be prepared for use with the cutout tool.Type: GrantFiled: October 29, 2013Date of Patent: December 27, 2016Assignee: MAKITA CORPORATIONInventors: Katsumi Okouchi, Yohei Ogino
