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;
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 including a two bar link including 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; and
the upper bar and lower bar are positioned in a stacked, substantially parallel arrangement in the door raised position, and the bars are spread apart to become near parallel in the door lowered position.

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.

10. An animal trap comprising:
-
a cage including a top, sides, a front door at a front cage opening, a rear, and a bottom, to form an enclosure for an animal, the top including a ceiling facing an interior of the enclosure; the front door pivotally attached at the ceiling including a raised position extending forward from the pivotal attachment and a lowered position angled toward the bottom, 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 at the front cage opening pivotally attached at a spaced location from the front door pivotal attachment with respective positions under the ceiling including a set position with the door raised and an extended position with the door lowered; a latch including a cam to selectively engage and latch the door, the latch biased by a set spring toward a latch set position, the latch being releasable to allow the door to move toward the lowered position; and the hold-close assembly is pressed from the extended position toward the set position at a pressing location below the ceiling at the front cage opening and the door is moved upward in a continuous motion to deflect the latch through the cam, near the end limit of this motion the latch automatically and passively latches the door to secure the door in the raised and set position. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An animal trap comprising:
-
a cage including a top, sides, a front door, a rear, and a bottom to form an enclosure, the top including a ceiling facing an interior 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, the lowered position confining the interior of the cage; a hold-close assembly connecting the ceiling to the front door having bar links including 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; wherein the door is pivoted to the ceiling at a position rearward of a front of the cage, the door closes in a rearward and downward motion, and the spaced first location is proximate a front of the cage forward of the door pivot location; means for actuating the hold-close assembly to bias the front door into the lowered position; a trip tray disposed proximate the rear and above the bottom of the cage, triggering the hold-close assembly; and the lower bar of the hold-close assembly being disposed below the ceiling and positioned to extend adjacent to the upper bar in the door raised position, the bars of the hold-close assembly pivoting as the door moves toward the lowered position including a closed position of the hold-close assembly wherein the hold-close assembly extends from the ceiling down to a lower location of the front door. - View Dependent Claims (18)
