TODAY’S PATENT – ELECTRIC LAWN MOWER
The Electric Lawn Mower was invented by Takao Kobayashi, Tetsuo Lida, Kenzou Shimada and Norikazu Shimizu on December 9, 2003 bearing patent number US6658829B2.
In the present invention, the switch operation mechanism may include a clutch mechanism, provided between the handling lever and the actuating member, for bringing the handling lever and the actuating member into or out of engagement with each other in response to the operation of the handling lever. The provision of such a clutch mechanism can effectively prevent erroneous switching operations of the operation mechanism.
Switch operation mechanism includes a handling lever pivotally connected to a portion of a handle, a generally-fan-shaped actuating member pivotally connected at its pivot portion to the handle in such a manner that the actuating member is pivotable in response to operation, by a human operator, of the handling lever, and a noncontact reed switch for turning on or off a cutter-driving electric motor in accordance with an ON/OFF state of the noncontact reed switch. The ON/OFF state of the noncontact reed switch is determined in accordance with pivoting movement, toward or away from the switch, of the actuating member responsive to the operation of the handling lever. With such arrangements, the switching operations of the operation mechanism can be performed accurately in a stable manner.
