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. The front door can be opened and set by a remotely located rooftop interface.

Claims

1. An animal trap comprising:

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

the front door pivotally attached at the ceiling including a raised position and a lowered position, the raised position exposing an interior of the cage to allow animal access into the enclosure, the lowered position confining the interior of the cage to block animal exit from the enclosure;

a hold-close assembly connecting the ceiling to the door to selectively lock the door in the lowered position, the hold-close assembly movable to release the door from a locked condition and further movable to bias and raise the door; and

a remote interface structure having a linkage to the door through a connecting link and through the hold-close assembly, the link extending rearward from the hold close assembly to the remote interface structure, the remote interface structure forcibly movable horizontally adjacent to the roof between a first position and a second position wherein horizontal motion of the remote interface structure causes the door to rise from the lowered position to the raised position.

2. The animal trap of claim 1, wherein the hold-close assembly includes at least one substantially rigid element comprising the linkage, and the element operates in compression to selectively secure the door closed, and the element operates in tension to open the door.

3. The animal trap of claim 2, wherein the hold-close assembly includes a first element, and the at least one rigid element is a second element, and the first element being a lift lever and the second element being a lower link.

4. The animal trap of claim 1, wherein the hold-close assembly connects the ceiling to the door and includes a two bar link with an upper bar pivotally attached at the ceiling at a separate and spaced first location from the pivotal attachment of the front door, the upper bar pivotally attached to a lower bar at second movable location, and the lower bar is pivotally attached to the door at a third movable location;

the lower bar of the hold-close assembly being disposed below the ceiling positioned to extend adjacent to the upper bar in the door raised position, the bars of the hold close assembly being released to pivot as the door moves toward the lowered position including a position of the hold close assembly wherein the hold close assembly extends from the ceiling down to a lower location of the door.

5. The animal trap of claim 1, wherein the connecting link is attached to the hold-close assembly below the ceiling and includes a connecting link segment that extends rearward from the hold-close assembly under the ceiling, and a further segment of the connecting link extends from below the ceiling to above the roof.

6. The animal trap of claim 5, wherein the remote interface structure is attached to a rear of the connecting link at a location above and adjacent to the roof.

7. The animal trap of claim 5, wherein a first element of the hold-close assembly is pivotally attached to the ceiling of the cage, the first element extends downward toward the door in the lowered door position, and in each of the lowered and raised door positions the connecting link is pivotally attached to the first element below a pivotal attachment of the first element to the cage whereby the connecting link is able to apply torque to the first element from a horizontal direction to rotate the first element about the pivotal attachment.

8. The animal trap of claim 1, wherein a rib extends upward from the roof near to the remote interface structure, and the remote interface structure forcibly movable by fingers of a single hand squeezing about the remote interface and the rib to draw the remote interface structure toward the rib.

9. An animal trap comprising:

a cage including a top, sides, a front opening, a front door, a rear, and a bottom to form an enclosure for an animal, the top including a ceiling facing an interior of the enclosure and a roof facing an exterior of the enclosure;

the front door pivotally attached to the cage at a door pivot location including a raised set position and a lowered position, the set position exposing an interior of the cage to allow animal access into the enclosure, the lowered position confining the interior of the cage to block animal exit from the enclosure;

a hold-close assembly pivotally attached to the cage at a location spaced from the door pivot location, the hold-close assembly connected to the door to selectively lock the door in the lowered position, the hold-close assembly movable to release the door from a locked condition; and

a remote interface structure outside of the enclosure positioned rearward of the front opening, a connecting link extending between the hold-close assembly and the remote interface structure, the remote interface structure movable laterally to cause the connecting link to also move laterally, the respective lateral motions converted at the hold-close assembly to a vertical motion of the hold-close assembly to cause the hold-close assembly to lift the door toward the raised position.

10. The animal trap of claim 9, wherein the hold-close assembly includes a lift lever and a lower link, the lift lever is connected to the lower link, and the lower link is connected to the door, and the lift lever moves upward to raise both of the lower link and the door.

11. The animal trap of claim 9, wherein the remote interface structure comprises a tab, forcible motion of the tab causes the door to rise to the raised set position, and the tab moves atop and adjacent the roof as it is so forcibly moved.

12. The animal trap of claim 11, wherein the tab is centrally positioned near to a carry handle of the trap.

13. The animal trap of claim 12, wherein the tab is positioned between the cage front opening and the carry handle.

14. The animal trap of claim 12, wherein the tab is atop and proximate a top plate.

15. The animal trap of claim 13, wherein a rib extends upward from the top plate, and the tab is forcibly movable by fingers of a single hand squeezing about the tab and the rib to draw the tab toward the rib.

16. The animal trap of claim 10, wherein the lift lever has a pivotal attachment to the cage near the top and near the front opening, the connecting link is pivotally attached to the lift lever vertically spaced from the lift lever pivotal attachment, and the connecting link causes the lift lever to rotate about the pivotal attachment when the connecting link is moved through its range of motion to raise the door.

17. The animal trap of claim 16, wherein the connecting link is pivotally attached to the lift lever below the lift lever pivotal attachment.

18. An animal trap comprising:

a cage including a top, sides, a front opening, a front door, a rear, and a bottom to form an enclosure for an animal, the top including a ceiling facing an interior of the enclosure and a roof facing an exterior of the enclosure;

the front door pivotally attached at the ceiling including a raised set position and a lowered position, the raised set position exposing an interior of the cage to allow animal access into the enclosure, the lowered position confining the interior of the cage to block animal exit from the enclosure;

a hold-close assembly including a lift lever and a lower link, the lift lever is pivotally attached at a first pivot to the cage at the front opening of the cage at the top of the cage, the lift lever pivotally connected to the lower link at a second pivot rearward of the front opening, the lower link further being connected to the door, and the lift lever extends downward from the top of the cage toward the door in the lowered position of the door; and

a rib of the lift lever positioned below the first pivot and above the second pivot in the lowered position of the door, the rib forming a lift lever grip including a rear of the rib usable to forcibly rotate the lift lever outward from the front opening and upward to cause the door to move to the door raised set position.

19. The animal trap of claim 18, wherein the rear of the rib is normally accessible to a hand positioned atop the trap behind the front opening wherein fingers of the hand can grip around a location of the first pivot to engage the lift lever grip.
