  • Combination string and blade trimmer with auxiliary blower function
    Patent number: 6460253
    Abstract: A trimming tool includes a selectable blade attachment for effecting a conversion between a string trimming mode and a blade trimming mode without requiring disassembly of the unit. The assembly includes a locking mechanism selectively engageable with a pivoting trimming blade that pivots between a retracted position and an extended position by centrifugal force. In one embodiment, the locking mechanism is reciprocated between the locked position and the unlocked position based on a rotation direction of the motor. The locking mechanism itself may also be reciprocated by centrifugal force. A spool lock, which is also positioned by centrifugal force, disables automatic string feeding in the blade trimming mode. The trimming tool may also be provided with a blower function incorporating a blower attachment readily attachable as a trimming guard of the trimming tool or a blower assembly integrated into the tool components.

  • Combination string and blade trimmer with auxiliary blower function
    Patent number: 6442845
    Abstract: A trimming tool includes a selectable blade attachment for effecting a conversion between a string trimming mode and a blade trimming mode without requiring disassembly of the unit. The assembly includes a locking mechanism (46) selectively engageable with a pivoting trimming blade (40) that pivots between a retracted position and an extended position by centrifugal force. In one embodiment, the locking mechanism is reciprocated between the locked position and the unlocked position based on a rotation direction of the motor. The locking mechanism itself may also be reciprocated by centrifugal force. A spool lock, which is also positioned by centrifugal force, disables automatic string feeding in the blade trimming mode. The trimming tool may also be provided with a blower function incorporating a blower attachment readily attachable as a trimming guard of the trimming tool, or a blower assembly integrated into the tool components.
