Patent ID: 7621194

Claim:
Commercial, residential, and recreational power equipment based on a singular motor usable on multiple host implements, where each host implement has a dedicated working piece for performing a particular work task, said power equipment comprising: a. a host implement having (i) a frame, (ii) a mounting block secured to the frame, said mounting block having a coupler hole extending therethrough and having a first latch component, (iii) a driven shaft connected to the frame with a first terminus and a second terminus, (iv) a working piece operably attached to the second terminus of the driven shaft, and (v) a first self-locating and locking coupler with a coupler terminus having opposed offset spiral ramps, said opposed offset spiral ramps extending in opposite directions a half-turn so as to create a stop wall at an end of each spiral ramp wherein said first self-locating and locking coupler is attached to the first terminus of the driven shaft and extends into the coupler hole in the mounting block; and b. a demountable motor removably secured to the host implement, said demountable motor having (i) a spacing block secured to the motor, said spacing block having a hole extending therethrough and having a second latch component for detachably attaching to the first latch component of the host implement, and (ii) a drive shaft with a second self-locating and locking coupler attached to a terminus thereof, said second self-locating and locking coupler with a coupler terminus having opposed offset spiral ramps, each said spiral ramp extending in opposite directions a half-turn so as to create a stop wall at an end of each spiral ramp wherein said second self-locating and locking coupler extends through the hole in the spacing block and is configured to mechanically mate with the first self-locating and locking coupler on the host implement for transferring a rotation force from the drive shaft of the demountable motor to the driven shaft of the host implement for driving the working piece, whereby the demountable motor is readily removed from the host implement by an unlatching and lifting action, which releases the first latch component from the second latch component, and is capable of being mounted on another host implement for performing another work task.
