Abstract

A live animal trap with improvements to ease of use, reliability and cost is disclosed. A simple repeatable one-hand set action lifts a front entry door. A hold-close assembly trips to secure the front door without sliding motions. A low friction latch and trip links thereto provide consistent set action resistant to shaking and undesired trip. A rear door is fitted next to a bait location to allow near vertical access for bait placement and unattended, unobstructed release. A changeable torque arm provides adjustable trip force. A trip tray is spaced above a floor to require a small set-up motion to access the bait and further ensure trip.

Claims

1. An animal trap, comprising:

a cage including a top, sides, a front, a front door at the front, a cage rear, and a bottom to form an enclosure for an animal, the top including a ceiling facing an interior of the enclosure and a cage length between the cage front and cage rear;

a rear door pivotally attached at a cage bottom rear including an open position and a closed position, the open position exposing an interior of the cage, the closed position confining the interior of the cage; and

a lock pivotally attached to a top of the rear door to selectively hold the rear door in the closed position, the lock elongated to extend forward along the top of the cage from the rear door to a lock front end, the lock front end selectively engaging the cage at a top of the cage near a central location of the cage length, the lock being operable from near the central location to disengage the lock from the cage and free the rear door to move from the closed position to the open position.

2. The animal trap of claim 1, wherein the lock includes a resilient arm, the arm extends from an arm attachment at the rear door to an arm distal end at the lock front end, a first position of the arm includes the lock front end being confined by a structure of the cage to hold the rear door closed, a second position of the arm includes the arm being deflected to be no longer confined by the structure of the cage to allow the rear door to be opened.

3. The animal trap of claim 2, wherein two opposed resilient arms extend forward from arm attachments at the rear door to arm distal ends at the lock front end.

4. The animal trap of claim 3, wherein the opposed arms are spaced apart at the arm attachments, the distal ends of the arms are relatively angled to be spaced closer together at the distal ends, and distal ends include tabs that selectively engage a confining structure of the cage.

5. The animal trap of claim 4, wherein an outward pressing force on the rear door causes the tabs to be further secured to the confining structure as a result of the relative angle between the arms.

6. The animal trap of claim 3, wherein the arms extend along an exterior of the top of the cage.

7. The animal trap of claim 6, wherein the arms include a loop, the loop extends upward from the top of the cage to be operable by a single hand moving the arms together to unlock and open the rear door.

8. The animal trap of claim 1, wherein the cage central location includes a top plate, and the lock front end engages the cage at a location of the top plate.

9. An animal trap, comprising:

a cage including a top, sides, a front, a front door at the front, a cage rear, and a bottom to form an enclosure for an animal, the top including a ceiling facing an interior of the enclosure and a cage length between the cage front and cage rear;

a rear door pivotally attached at a cage rear including an open position and a closed position, the open position exposing an interior of the cage, the closed position confining the interior of the cage; and

a lock attached to the rear door to selectively hold the rear door in the closed position, the lock includes a resilient arm elongated to extend from an arm attachment at the rear door to an arm distal end at a lock front end, a first position of the arm includes the lock front end being confined by a structure of the cage to hold the rear door closed, a second position of the arm includes the arm being deflected to be no longer confined by the structure of the cage to allow the rear door to be opened.

10. The animal trap of claim 9, wherein the lock front end engages the cage near a central location of the cage length, and the lock is operable from near the central location.

11. The animal trap of claim 9, wherein the lock front end is resiliently movable with respect to the structure of the cage, and an outward force on the rear door causes the lock front end to be biased to be further secured by the confining structure.

12. The animal trap of claim 9, wherein the lock is operable from a position substantially in front of the rear door.

13. The animal trap of claim 9, wherein the lock includes two arms and the second position includes each arm being deflected away from the confining structure of the cage.

14. The animal trap of claim 13, wherein the two arms are spaced from each other at the lock front end and the arms are squeezed together to be in the second position.

15. An animal trap, comprising:

a cage including a top, sides, a front, rear, a cage length between the cage front and cage rear, and a cage bottom to form an elongated enclosure including a cage interior within the enclosure and an external region outside of the enclosure;

a front door pivotally attached at the front of the enclosure;

a rear door pivotally attached by a hinge adjacent a cage rearmost end including an open position and a closed position, the open position exposing an interior of the cage, the closed position confining the interior of the cage;

the rear door extending forward within the interior of the cage at a rear door location spaced from the hinge, the rear door thereby linked to the interior of the cage to add structural support to the cage to resist forcible distortion of the cage; and

a lock selectively linking the rear door to the cage through an arm of the lock to hold the rear door in the closed position, the lock operable from the external region to deflect the arm and disengage the rear door from the cage to free the rear door to move from the closed position to the open position.

16. The animal trap of claim 15, wherein the rear door extends forward at a bent corner of the rear door.

17. The animal trap of claim 16, wherein the lock is attached to the rear door at a location adjacent to the bent corner.

18. The animal trap of claim 15, wherein the lock is pivotally attached to the rear door at a rear door location spaced from the hinge.

19. The animal trap of claim 15, wherein a first position of the arm includes the lock front end being confined by a structure of the cage to hold the rear door closed, a second position of the arm includes the arm being deflected to be no longer confined by the structure of the cage to allow the rear door to be opened.

20. The animal trap of claim 19, wherein the lock includes two arms and the second position includes each arm being deflected away from the confining structure of the cage.
