A retractable leash device is comprised of a housing with a handle, and a leash
wound around an internal reel. The reel is biased by a spring to automatically
retract the leash. A momentary unidirectional lock in the housing is arranged to
be normally disengaged from unidirectional teeth on the reel. When the momentary
unidirectional lock is actuated, the reel is engaged by a ratchet to prevent rotation
in the release direction but permit rotation in the retract direction. A toggle
lock in the housing is movable between an unlocked position away from the reel,
and a locked position between cogs on the reel. A geared rotation damper is engaged
with a concentric gear on the reel to limit retraction speed. A clip attached to
the housing may be clipped around the leash when the leash is wrapped around a
fixed object.
