Patent number: 9604352Abstract: An impact tool can be operated by generating an impact using an internal mechanism. The impact tool includes a control unit and sensors. The control unit controls the internal mechanism. The sensors output a signal for operating the internal mechanism or a signal for preparing the operation of the internal mechanism, to the control unit. Until a predetermined condition is established after the internal mechanism is operated, the control unit does not accept the input of the sensors.Type: GrantFiled: September 6, 2013Date of Patent: March 28, 2017Assignee: MAX CO., LTD.Inventors: Tsuyoshi Kobayashi, Norihiro Nagai, Yasushi Yokochi

Patent number: 8308038Abstract: A part clamp is temporarily held in a short cylindrical portion provided on a contact arm of a nailing machine and is nailed to a building body or the like by the nailing machine. The part clamp is provided with a base portion having a through hole at its center for inserting a nail therethrough, and an engaging portions for engaging with the short cylindrical portion. When the part clamp is pushed in the axial direction of an injection port of the nailing machine, the part clamp is temporarily held in the short cylindrical portion. The load to push the part clamp to engage with the short cylindrical portion is lower than the load to push the contact arm to slide along the injection port.Type: GrantFiled: May 22, 2012Date of Patent: November 13, 2012Assignee: Max Co., Ltd.Inventors: Hiroshi Tanaka, Yasushi Yokochi, Satoshi Osuga, Hiroshi Shiokawa

Publication number: 20090032563Abstract: A containing portion 22 for a motor is formed at an upper wall of a combustion chamber 11 of a gas combustion type striking machine. A shaft 21 of a motor 20 is coupled with a rotating fan 18 penetrated through a bottom portion of the containing portion 22 to face the combustion chamber 11. A mixture gas provided by being agitated and mixed by the rotating fan 18 is ignited and combusted at inside of the combustion chamber 11. A fastener is struck by a pressure of a combustion gas produced by the combustion. The motor 20 is contained in the containing portion 22 by way of damping members 25, 26 in a shape of a short cylinder respectively having an elasticity at upper and lower portions thereof. The respective damping members 25, 26 are formed with a plural of groove holes 28 prolonged in an up and down direction at constant intervals along a peripheral direction.Type: ApplicationFiled: March 30, 2006Publication date: February 5, 2009Inventor: Yasushi Yokochi
