Patent number: 11667020Abstract: In a driving tool, during and/or after a driving operation has been completed, a restriction member is retained in an on-position by a cam. An energizing switch is retained in an on-state by an actuation portion of the restriction member. Because of this configuration, if a trigger is released during and/or after the driving operation has been completed, an electric motor continues to be activated, which causes a driver to return to a standby position.Type: GrantFiled: July 28, 2021Date of Patent: June 6, 2023Assignee: MAKITA CORPORATIONInventors: Shun Kuriki, Yukiyasu Okouchi, Yoshitaka Akiba, Norikazu Baba

Patent number: 7246444Abstract: A cutting tool that improves operability by facilitating operation of a lever for operating a clamp mechanism of a guide member is provided. A clamp mechanism is constituted by a clamp pin that protrudes its distal end to the outside of the blade case while penetrating a depth guide and the blade case, a first lever that is connected to the distal end of the clamp pin and directly moves the clamp pin in the axial direction, and a second lever that is connected to the upper portion of the first lever through a connecting pin and has a cam lever. When the second lever is rotated toward the blade case, the cam lever presses the connecting pin to tilt the first lever, whereby the clamp pin is pulled outward. As a result, the depth guide is pressed to the inner surface of the blade case and clamped.Type: GrantFiled: November 15, 2005Date of Patent: July 24, 2007Assignee: Makita CorporationInventors: Tomonobu Nashimoto, Yukiyasu Okouchi, Takahiro Kamiya

Patent number: 6145727Abstract: A pneumatic tool, such as a nailer, includes a housing, a cylinder disposed within the housing, and a piston slidably movable within the cylinder. The piston has a driver for driving fasteners, such as nails. An upper piston chamber and a lower piston chamber are defined within the cylinder on an upper side and a lower side of the piston, respectively. A control device is provided for controlling the supply of compressed air from a compressed air supply device to the upper piston chamber and to the lower piston chamber to drive the fasteners into a workpiece. The control device includes a variable pressure chamber and a valve. The variable pressure chamber is always connected to the compressed air supply device.
