Pet behavioral restraint device

Pet behavioral restraint device that covers the face in response to leash tension

This technology consists of a collar, a support frame fixed to the back, a shield that rotates forward via elastic force to cover the face, and an activation trigger that releases the stored shield when leash tension is applied. The trigger uses a release lever, a tether, and a magnetic set to adjust the locking force.

As dog bite incidents have become a social issue, there have been calls to mandate muzzles even for small dogs, but critics argue that constant muzzling excessively restricts animal freedom and welfare. Existing retractable muzzles also have limitations in that they cannot immediately block vision and the mouth in emergency situations.

This technology functions as a standard leash during normal use, but in the event of a sudden attack or dash into traffic, the strong tension on the leash causes the shield to deploy instantly, covering the animal's eyes and mouth. Applicable to walking harnesses, pet training/boarding services, and veterinary transport, it ensures pet freedom while preventing personal injury and traffic accidents.

Key Features:

• A collar worn around the pet's neck and a support frame fixed to the back, featuring a pivot point on one end rotatably coupled to both sides of the collar.
• A shield that rotates forward via elastic force to cover and block the pet's face, and rotates backward to be stored in the support frame.
• An activation trigger consisting of a release lever, a tether, and a magnetic unit that secures the stored shield and releases it when tension is applied to the leash.
• A configuration featuring a length adjustment unit that changes the locking force using magnet sets of varying magnetic strength and extends or retracts the support frame and operating rod in stages.
