    Abstract: A chip deflector repositionable as needed relative to a bottom work contacting surface of a hand-held power router. The chip deflector can be positioned in a shielding location below the bottom work contacting surface of the router. When the chip deflector is in the shielding position and the router is held so that the deflector is between the cutter and the worker it will deflect debris away from the operator. When not useful the chip deflector can instantly be repositioned to a non-shielding location flush with or above the bottom work contacting surface of the router. When in the non-shielding location no portion of the chip deflector protrudes beyond the bottom work contacting surface of the router thereby allowing the router to perform all basic routing without obstruction. Repositioning requires no tools or downtime plus safety and comfort are enhanced. Embodiments may be provided as original equipment or aftermarket retrofits.

  • Publication number: 20120241049
    Abstract: In an electric power tool, a controller, a capacitor, a terminal stand, a speed change controller, and a switch are arranged at positions offset from the axis of a spindle so as not to overlap the spindle as seen in a direction corresponding to the direction in which the spindle axially extends. The controller, the capacitor, the terminal stand, the speed change controller, and the switch are located so as to overlap a part of a drive motor as seen in a direction orthogonal to the direction in which the spindle axially extends. The controller, the capacitor, the terminal stand, the speed change controller, and the switch are located so as to overlap at least a part of a field as seen in a direction corresponding to the direction in which the spindle axially extends.

  • Publication number: 20120045290
    Abstract: An electrical power tool may include a base capable of contacting the work-piece, a tool main body detachably attached to the base, and an elevating mechanism that is capable of changing a relative position of the tool main body to the base. The elevating mechanism includes a male elevating member that is releasably integrated with the tool main body, a female elevating member that is attached to the base and is capable of relatively raising and lowering the male elevating member, and an integrating mechanism that is capable of releasably integrating the male elevating member with the tool main body. The tool main body is capable of being removed from the base while the male elevating member is left in the base when the male elevating member is released from the tool main body by operating the integrating mechanism.

  • Patent number: 8087437
    Abstract: A router includes a base, a motor housing supported by the base for movement along a first axis, and an adjustment mechanism having a shaft, with a thread portion, connected to the motor housing for rotation about a second axis. The adjustment mechanism also includes a unitarily formed lock mechanism supported by the base. The lock mechanism includes a thread-engaging member that, when engaged with the thread portion, causes small changes to the position of the housing relative to the base in response to rotation of the shaft. The lock mechanism is movable between an engaged position, in which the thread-engaging member engages the thread portion, and a disengaged position, in which the thread-engaging member disengages the thread portion and the housing is freely movable relative to the base to provide course adjustment of the position of the housing relative to the base.

  • Patent number: 8056243
    Abstract: A power tool comprising a housing displaceably mounted to a foot plate, a blade, a motor, an electric switch and an interlock for controlling movement of the housing with respect to the foot plate. The interlock has a control button mounted to one of the housing or foot plate which cooperates with a channel fixed in relation to the other of the housing or foot plate. The control button can select between a plunge cut mode wherein the blade can protrude below the foot plate, or a blade change mode wherein the blade is prepared for a blade change operation. The channel comprises a major leg in communication with a minor leg. Cooperation between the button and the major leg selects the plunge cut mode. Cooperation between the button and the minor leg selects the blade change mode. The interlock may also comprise a housing lock and a spindle lock.
