  • Patent number: 8490322
    Abstract: An animal trap has a base, an upper jaw pivotally coupled with the base so that it is movable between a closed position and an open position, and a set arm that is pivotally coupled with the upper jaw and moveable between a collapsed position and an open position. In its open position, the set arm provides a lever whereby application of a force to the set arm moves the upper jaw toward its open position. A method for trapping an animal includes moving a trap between a first position, where the upper jaw is closed, and the set arm is collapsed, and a second position, where the upper jaw is closed and the set arm is open. The method further includes the step of moving the trap between a second position and a third position in which the upper jaw is open, and the set arm is open.

  • Publication number: 20110162255
    Abstract: Trap for mice and rats comprising two legs (1, 2) with jaws (9, 10), where one leg (1) is horizontally moveable towards a fixed leg (2) via an intermediary link (5-8). The fixed leg rests on a base-plate (3) and has a cover-lid (4) at the top. The legs (1, 2) are fitted with grip handles (11, 12) at the opposite end. The jaws (9, 10) are acted upon by a draw spring (22) or spring clip (31), whose direction of force works near the fulcrum of the legs (1, 2) in the open position of the trap. The closing movement is triggered by a bait-carrier (17, 18) with lever (16) fitted between the legs (1, 2), and which is flexibly suspended at the back. Its reverse movement is stopped by a stop device (26) behind the grip handle of the fixed leg. The bait-carrier (17, 18) can move in several directions, upwards, downwards and outwards. The bait can be mounted in and under the bait-carrier (17, 18, 28).

  • Publication number: 20110126446
    Abstract: This invention relates to a mouse trap having retractable biting portions. It includes a base, a movable portion, and a trigger. The base has a front seat which has a lower outer edge and several receiving holes. The movable portion is disposed on the base and has a front frame portion and a restoring force generating element. The front frame portion is disposed with an upper outer edge and a plurality of retractable biting portions. These retractable biting portions are corresponding to the receiving holes. The restoring force generating element is able to urge the movable portion moving from the first position to the second position. So, it can capture a mouse quickly. The protruded length of each retractable biting portion is automatically adjusted. Hence, the captured mouse will not bleed so it is sanitary. The capture method is humane without sacrificing its capturing result. The safety of the product can be enhanced. Plus, the biting depth is automatically adjusted.

  • Publication number: 20100257773
    Abstract: An improved mousetrap has an upper jaw pivotally mounted with a lower jaw, and a bait platform mounted between the upper and lower jaws, The bait platform acts as a trigger to initiate jaw closure when depressed. A circumferential spring for closing the jaws around the bait platform encircles the jaws and is retained in a retaining groove of the lower jaw. The upper jaw has a rear, lower corner for retaining the spring when the jaws are open; and a rear, upper corner for retaining the spring when the jaws are closed. Contractile force of the spring pulls the spring from the lower corner toward the upper corner, to complete jaw closure.

  • Patent number: 6415544
    Abstract: A plastic jaw or striker with downwardly facing teeth is pivotally mounted to a plastic base with mating upwardly facing teeth. A plastic trigger hangs from the base, and a coil spring extends between the jaw and the base rearward of the trigger. The spring holds the jaw in the set position, by engaging the rear of the jaw against the rear of the base. The trap is tuned to be not overly sensitive, avoiding springing of the trap by vibrations or insubstantial rodent entry. The spring or tension axis does not go through the trigger, simplifying construction and arrangement of parts. The open position is limited by the jaw engaging the base. The jaw is just over-center when set, such that a small movement towards closure does not trigger it. The trigger requires fairly large movement, facilitated by the raised pivot axis, to trigger the trap.

  • Patent number: 4766693
    Abstract: Conventional traps often catch animals by the leg rather than killing them outright. This trap utilizes two spring actuated jaws closing upon a base ring but with stops on the base ring maintaining the movable jaws slightly open when sprung so that an animal cannot be caught by the leg. The trip mechanism is such that it can be actuated by pressure upon any part of the pan thus releasing the jaws and killing the animal with a blow to the head or neck area. The spring mechanism is such that if large animals are accidentally caught by the foot, they are able to pull foot free.

  • Patent number: 4557068
    Abstract: A padded leghold trap of the pivoting jaw type includes recessed portions of the jaws in which respective pads are disposed. The pads each have concave facing surfaces with an inner edge that barely touches the inner edge of the other pad in the sprung position of the jaws, leaving the remainder of the concave facing surfaces mutually spaced. A trapped animal is held between the padded jaws which spring closed and traps the animal's leg without breaking the leg or causing edema. Attempts by the trapped animal to pull its trapped limb from between the jaws causes the radially inner pad edges to roll over toward the limb and thereby increase the retention forces. A retainer for the pad is disposed over an access slot in the pad, which access slot is provided to deploy the pad on the jaw. The retainer includes a bent lip which deforms the pad toward the jaw to prevent the pad from being pulled off the jaw by a trapped animal.

  • Patent number: 4266364
    Abstract: Apparatus by which a steel leg-hold trap is rendered humane so that the trapped animal is recovered alive and uninjured. A resilient material, such as vulcanized rubber, is removably affixed to the opposed jaws of the trap so that the animal's leg is uninjured when the jaws are closed thereon. The first reaction of any animal caught in the leg-hold trap is to bite and chew on the trap. A nipple extends from the resilient material and contains a substance, such as a tranquilizer, which subdues the animal when the substance is orally ingested. The nipple is a hollow chamber which extends away from the trap jaws so that the animal, when trapped, inherently attacks and bites the nipple, whereupon the chemical substance is released from the chamber and enters the oral cavity of the animal, causing the animal to become subdued. A tranquilizer is preferably placed within the nipple so that should the incorrect animal be trapped, he can subsequently be released unharmed.

    Abstract: Disclosed is a padded jaw animal trap with improved holding power in order to retain an animal caught in the trap. The padding of each jaw has a face with a concave geometrical arrangement such that when an animal is caught in the trap, the face deforms to a nearly planar surface forcing ridges of flesh on either side of the face. It is this ridge of flesh which increases the holding power of the padded jaw trap over the prior art.

The point may be located at a distance from the axis of rotation about the same as or greater than the distance of said jaw from this axis. The actuator rings of the trap according to this construction are adapted to exert sufficient clamping force on the jaws of the trap to quickly kill a desired animal trapped therein.
