Abstract
A motorized hose reel with a positive locking mechanism includes a spool that is rotatably supported by a support frame, a motor in driving communication with the spool and a locking pin. The locking pin is movable to any one of three positions. In the first position, a spring forces the locking pin to engage a corresponding aperture in the hose reel spool. As the locking pin is rotated, a shaft extending radially from the locking pin engages a track formed in the housing. This causes the locking pin to withdraw from the hose reel spool against the force of the spring. Further rotation of the locking pin causes the radially-extending shaft to engage a detent, which holds the locking pin away from the hose reel spool. Still further rotation of the locking pin causes the radially-extending shaft to close a switch, which completes an electrical circuit to the motor.
