Definitions

  • This invention relates to a leash for an animal, and in particular, to one which is remotely detachable from the animal, such as from the collar of a dog, by means disposed at the hand of the user.
  • Dogs are used by security officers when they act in an official capacity as such, as well as by men and women who, though not acting in an official capacity, nevertheless take a walk or otherwise venture from their homes only in the company of a dog on a leash.
  • there may be occasion to release the dog from the leash so that he can track or pursue a suspect, or fend off an attacker without the constraint of the leash.
  • various leashes have been developed which are equipped with a quick release catch mechanism on the distal end thereof, so that the leash can be quickly detached from the dog's collar when the user wishes to release the dog for any of these purposes.
  • the present invention relates to an animal leash which is remotely detachable from the collar of the animal at the hand of the user.
  • the leash comprises an elongated, flexible tether having releasable collar engaging catch means adjacent one end thereof, and a hand grip adjacent the other end thereof.
  • the catch means include a pair of relatively reciprocable jaws which are openaBle to a position in which they enable the catch means to be engaged about an attachment point on the collar, and closeable when the catch means are so engaged, to a position in which they enable the tether to be secured to the collar of the animal.
  • the leash also comprises latch means which are mounted on the tether to reciprocate between a position in which they engage with the catch means to lock the jaws in the closed position thereof, and a position in which they disengage from the catch means to unlock the jaws for rec procation to the open position thereof.
  • the leash is equipped with manual release means for the latch means, including a hand actuator which is disposed on the tether adjacent the hand grip thereof, and interconnected with the latch means to reciprocate the latch means between the jaw-locking position and the jaw-unlocking position thereof.
  • the latch means are yieldably biased to assume the jaw-locking position thereof, and the latch release means are operable to reciprocate the latch means against the bias thereon.
  • the jaws are relatively reciprocable in the direction relatively toward the hand grip to close, and the latch means include a retainer element which is yieldably biased in the direction relatively away from the hand grip to engage the jaws in the closed position thereof.
  • the jaws are pivotally interconnected with one another at the distal end of the tether and openable to a position wherein they are disposed in tandem with one another axially of the tether, and closeable to a position wherein they are disposed abreast of one another relatively rearward of the pivotal connection therebetween; and in such a case, the retainer element has a recess in the relatively forward end thereof within which the jaws are received when engaged by the element in the closed position thereof.
  • the retainer element takes the form of a sleeve which is reciprocably mounted on a rigid tenon at the distal end of the tether, and yieldably biased relatively toward the distal end of the tenon by a coiled spring which is caged in the sleeve; and in such a case, the latch release means further include an elongated cord which interconnects the actuator with the sleeve to reciprocate the same against the bias of the spring when the jaws are to be unlocked for reciprocation to the open position thereof.
  • the body of the tether is hollow, and the cord extends through the body of the same.
  • the tether preferably has an eye formed on the aforesaid other end portion thereof, to serve as a handle for grasping the tether, and the cord opens into the eye of the handle and has an eye on the same within the eye of the handle, so that a user grasping the handle can insert one finger in the eye of the cord and use it as a trigger to retract the cord and reciprocate the sleeve against the bias of the spring when the jaws are to be unlocked for reciprocation to the open position thereof.

  • the head 30 of the attachment ring 28 of the catch mechanism is equipped with an oblong flange 50, and a pair of coiled springs 52 is caged between the flange 50 and the bulkhead 48, about the tenons, to bias the sleeve 46 into the jaw-locking position thereof.
