Abstract: A rat trap wheel chock integrates a trap in the body of a wheel chock for capturing rats and other rodents. The wheel chock has at least one wheel bracing face and one ancillary face, with the wheel bracing face being designed to block a wheel (such as from an aircraft) from moving while the ancillary face provides an entrance to the interior of the wheel chock. The wheel chock has a chamber inside that forms part of the trap. Animals are capable of entering the trap through a one way entrance door placed in a lateral opening which is cut from the ancillary surface. The door is longer/taller than the door frame, which prevents the door from opening away from the chamber. A bottom surface has a bottom opening and sealing access door, which can be opened to dispose of captured animals.

This threshold is determined by an accelerometer present in the trap. Once the user receives a signal or alert on any Bluetooth® enabled device, they can check the trap and dispose of the pest or rodent.

Abstract: The animal trap includes an enclosure for containing a number of relatively large animals. An entry path (game trail, etc.) extends from the enclosure to an automated drop gate at the entrance, or may comprise the enclosure with a gate at each end. At least one double articulated trip arm is placed along the entry path. The trip arm does not actuate the gate when moved toward the enclosure, i.e., when animals pass through the entry path from the drop gate entrance to the enclosure. However, animals passing in the opposite direction move the trip arm(s) toward the gate, causing at least one trip arm to close a circuit and drop the gate to close the trap. The trap is thus configured to capture a number of herd animals, e.g., wild pigs, passing from the gate toward the enclosure, before one of the animals turns back and trips the gate.

Abstract: A trap for gophers and underground pests includes: a spring; a catapult attached to the spring having an open position and a closed position and a distal end from the spring, the spring rotating the catapult; a snare for the animal having a size that reduces when the snare is pulled; a snare coupling on the distal end of the catapult, attached to the snare so that the catapult pulls on the snare; a suppression lever to releasably hold the catapult open; a footplate to releasably retain the suppression lever; and an actuator to press upon the footplate in the presence of the animal. The actuator presses upon the footplate, which releases the suppression lever, which releases the catapult to transition from the open position to the closed position, which causes the snare coupling to pull on the snare, which reduces the size of the snare, catching the animal.

Abstract: A door lock mechanism for an animal trap, an animal trap, and a method of capturing animals, typically, rodents and small animals. The door locking mechanism, trap and method employ a gravity-driven door and lock used for a door having a ledge and two bars that are pivotally mounted above the door. When activated by a release mechanism, the door and bars pivotally deflect whereby the bars engage the ledge on the closed door and prevent the door from being opened. The door lock mechanism may be used on any size and shape trap, but one typical trap for which the mechanism can be used is disclosed. A trap entrance arrangement having a conduit for leading animals to the entrance of a trap, that can be used with or without the disclosed door lock mechanism, is also provided.
