Publication number: 20110094763Abstract: An auto hammer having a housing having a grip portion defining a central axis and a head assembly including a striking device which has a striking rod defining a central axis. The striking device is pivotable relative to the grip portion and the angle between the central axis of the grip and the central axis of the striking rod can range between 60° and 180°. The auto hammer thus provides a pivotable striking device and is thereby suitable for different working circumstances.Type: ApplicationFiled: February 4, 2010Publication date: April 28, 2011Applicant: Chervon LimitedInventor: Gan Wei

Publication number: 20110011912Abstract: An auto hammer has a housing body and a nozzle portion connected to the housing. The housing body contains a striking device therein. The nozzle portion contains a sleeve and a sleeve support. The sleeve is retractable within the sleeve support and contains a nail attracting device therein. A magnet is arranged in the nail attracting device and is supported by at least one spring. The nail attracting device of the auto hammer is thus arranged in the sleeve and the spring is used to support the magnet to increase stability. After being attracted, the nail is positioned along the centerline of the sleeve so it becomes more convenient to use the nail attracting device.Type: ApplicationFiled: February 4, 2010Publication date: January 20, 2011Applicant: Chervon LimitedInventors: Gan Wei, Masatoshi Fukinuki

Patent number: 7731571Abstract: An electric sanding machine has a housing with a drive device disposed therein, a base plate disposed under the housing, and a driven shaft for driving the base plate. A sanding device is attached to the base plate. The housing has a drive device housing part substantially perpendicular to the base plate and a grip housing part substantially parallel to the base plate. A cross section of the housing in a vertical direction is substantially L-shaped. The drive device is disposed in the drive device housing part while the driven shaft is located in the grip housing part so that the drive device is departed from the driven shaft in a radius direction of the driven shaft. With this arrangement, the sanding machine is provided with stronger power and has a smaller contour size which may be controlled more effectively.Type: GrantFiled: April 25, 2008Date of Patent: June 8, 2010Assignee: Chervon LimitedInventors: Masatoshi Fukinuki, Gan Wei

Publication number: 20100120340Abstract: A sander according to the present invention comprising a housing, a motor and a transmission mounted within the housing, a sanding plate mounted below the housing, a battery pack mounted at the rear end of the housing and a balance means mounted on either the housing or the sanding plate. The balance means includes a balance element disposed in the front part of the sander. The balance element is balanced with the battery pack, which solves the balance problem of the DC sanders known in the prior art while still providing a battery pack that can satisfy the power requirements of the sander.Type: ApplicationFiled: November 9, 2009Publication date: May 13, 2010Inventors: Masatoshi Fukinuki, Gan Wei

Publication number: 20100089965Abstract: A nailer device has a housing containing a motor and a transmission mechanism. The housing has a nozzle portion with a striking rod for striking a nail arranged therein, the striking rod being moved in a reciprocating manner. A rotating shall is mounted in the housing and the rotating shaft is coupled to the output shaft of the motor through the transmission mechanism. An impact member surrounds the rotating shaft and is moved with the rotating shaft. Corresponding slots are formed on the rotating shaft and the impact member respectively and mate with each other with engagement members being contained in the corresponding slots.Type: ApplicationFiled: September 23, 2009Publication date: April 15, 2010Applicant: Chervon LimitedInventors: Masatoshi Fukinuki, Toshinari Yamaoka, Gan Wei

Publication number: 20100089967Abstract: A nailer device has a housing containing a motor, a gear box, a transmission mechanism, and a striking rod. The motor, the gear box, and the transmission mechanism cooperate to cause the striking rod to be moved back and forth. The striking rod has a peripheral outer surface and a longitudinal axis and the striking rod and the gear box are connected through a sliding connection structure which allows the striking rod to be moved along its longitudinal axis and which prevents the striking rod from rotating around its longitudinal axis.Type: ApplicationFiled: November 19, 2009Publication date: April 15, 2010Applicant: Chervon Limited.Inventors: Masatoshi Fukinuki, Toshinari Yamaoka, Gan Wei

Publication number: 20100089968Abstract: A nailer device includes a housing having a nozzle portion formed in an upper end thereof. A motor and a rotary-linear motion transmission mechanism are arranged in the housing and the rotary-linear transmission mechanism functions to couple an output shaft of the motor to a striking rod disposed in the nozzle portion to thereby move the striking rod in a reciprocating manner. A bias device exerts a force on the striking rod towards the outside of the housing along a longitudinal direction of the striking rod.Type: ApplicationFiled: November 19, 2009Publication date: April 15, 2010Applicant: Chevon LimitedInventors: Masatoshi Fukinuki, Toshinari Yamaoka, Gan Wei

Patent number: 7048605Abstract: A bobble head doll shaker includes a base and housing and a supporting platform that is hingedly mounted to the housing. A motor drives an agitator that lifts and releases the supporting platform, thereby imparting an oscillating motion to a bobble head doll supported on the platform. The agitator includes engagement portions that lift the supporting platform. The motor has variable speed and agitator elements having different profiles that may be interchanged to achieve a greater variability of the oscillating motion. Moreover, with the hinge attachment, the bobble head doll's position and corresponding movement may be varied by changing its location on the supporting platform. A riser element may also be placed under the doll to increase the instability of the doll and provide for further varying the bobble head doll motion.Type: GrantFiled: November 25, 2003Date of Patent: May 23, 2006Inventors: Grant Hawthorne, David Kapell, Andrew Comfort, Thomas Cheung, Gan Wei Xiong, Liao Wang Xian, Lowell Fritzke
