  • Patent number: 5595143
    Abstract: The leash apparatus includes two commercially available self retracting leashes, one carried in a pack carried on the leashed animal and the other carried by the user. Each leash has a button which, when the button is pushed, locks the leash line reel in the leash. The button on the user held leash is manually operated. The button on the animal carried leash is operated by remote control. A transmitter operated by the user sends a signal to a receiver/relay in the pack. The receiver/relay switches on power from a battery in the pack to a solenoid which activates the button. The transmitter may be attached to the user held leash such that it is operated when the reel-locking button on that leash is pushed, providing automatic simultaneous locking of both reels. Using two leashes inherently doubles the leash length and overall retraction speed with no change in range of tension in the leash line. In an alternate embodiment the transmitter/receiver relay equipment has two channels, individually operable.
