Remote-activated animal trap

Abstract

A fast closing remotely activated animal trap gate includes a gate with a wire mesh and a frame to hold the gate, with the gate moving within the frame between an open position and a closed position. A cable, interacting with a system of weight-reducing pulley wheels, holds the gate within the frame in an open position, and a release rod holds the cable in place. The release rod is retracted in order to allow release of the cable and consequent movement of the gate from the open position to the closed position. In some embodiments, low friction ball-bearing trolley wheels assist in the fast, downward fall of the gate.

DETAILED DESCRIPTION OF THE INVENTION

(6) In some of its many embodiments, the present general inventive concept includes a gate and a frame to hold the gate, with the gate moving within the frame between an open position and a closed position. A cable, interacting with a system of weight-reducing pulley wheels, holds the gate within the frame in an open position, and a release rod holds the cable in place.

(7) Turning to the figures, FIG. 1 illustrates one example embodiment of a fast closing remotely activated animal trap gate according to the present general inventive concept. In the illustrated example embodiment, a fast closing remotely activated animal trap gate 10 includes a substantially stationary frame 20 and a moving gate 30. The frame 20 generally includes a top frame member 22 and a bottom frame member 24, with the top frame member 22 being supported by two vertical members 26a and 26b. The gate 30 generally includes a wire mesh 35 suspended within a gate structure that includes a top piece 32, a bottom piece 34, and side pieces 36a and 36b. In several embodiments, the gate 30 fits within the frame 20 in such a way that the side pieces 36a and 36b of the gate 30 slide within machined channels in the side members 26a and 26b of the frame 20. In some embodiments, the side pieces 36a and 36b of the gate 30 move on low friction ball-bearing wheels within the machined channels in the side members 26a and 26b of the frame 20.

(8) FIG. 1 illustrates the example embodiment of a fast closing remotely activated animal trap gate 10 in an up or open position (or condition, or state); that is, the gate 30 is elevated some distance above the ground, providing substantial separation (generally between 1 and 4 feet) between the bottom piece 34 of the gate 30 and the bottom frame member 24. FIG. 2 shows the same example embodiment fast closing remotely activated animal trap gate 10 in a down or closed position (or condition, or state), in which the gate 30 has been lowered (generally by way of the side pieces 36a and 36b sliding down within the machined channels in the side members 26a and 26b of the frame 20).

(9) In order to capture game (such as wild hogs), generally it is preferable for the gate to be capable of closing fastthat is, moving quickly from the open position shown in FIG. 1 to the closed position shown in FIG. 2. Generally, the fast closure of the gate is accomplished through the operation of a cable interacting with a release pin or rod. As shown in FIGS. 1 and 2, and as shown in the close-up view in FIG. 3, the example embodiment device 10 generally includes a motor box or subassembly 40 that drives the operation of a release rod 42 that interacts with a conduit housing 44. (In some embodiments, the conduit housing 44 is fabricated from PVC or a similar low friction material.) The release rod 42 interacts with a cable 50, and this cable 50 interacts with a weight-reducing pulley system both to hold the gate 30 in an open position and to control and facilitate the movement of the gate 30 from the open position to the closed position. When the gate 30 is in the open position, as shown in FIG. 1, a first end loop 51 in the cable 50 is wrapped around the release rod 42, generally through an opening 46 in the conduit housing 44. In this position, the rod 42, supported by the conduit housing 44, holds the cable 50 in place. The length of the cable 50 is wrapped around a number of weight-reducing pulley wheels: two weight-reducing pulley wheels 52a and 52b that are mounted onto a cross-beam 38 in the middle of the gate 30, and two weight-reducing pulley wheels 54a and 54b that are mounted onto a cross-beam 28 that is below the top frame member 22 (and generally connected to the top frame member 22 by at least a pair of connector members 29a and 29b). The other end of the coil 50 includes a second end loop 58 held in place by a cable bolt 56, which is connected to the gate 30.

(10) To close the gate 30, a wireless signal or other electronic communication is sent to the motor box 40, within which a receiver receives the signal and conveys it to a controller. The controller then operates a motor to retract the release rod 42, drawing the rod 42 away from the end loop 51 of the cable 50. When the release rod 42 is retracted, the first end of the cable pulls away from the conduit housing 44. The full weight of the gate 30 pulls the gate downwards, with the cable 50 passing through the weight-reducing pulley wheels as the gate 30 rapidly descends. In some embodiments, low-friction ball-bearing trolley wheels assist in the rapid descent of the gate 30 and reduce the incidence hang ups encountered in other gates in the art.

(11) FIG. 4 illustrates generally one example embodiment of the motor box 40 shown in the previous figures. As shown in FIG. 4, the example embodiment motor box 40 includes a housing 405 that holds an external antenna 410 to receive a signal from a remote controller. The external antenna 410 passes the signal to a receiver and relay 420, which draws electricity from a power source 430 and which controls an actuator 440, which drives the release rod 42.

(12) A fast closing remotely activated animal trap gate according to the present general inventive concept provides a gate that can be closed quickly in order to trap wild animals, without a human operator being physically close to the gate (which might frighten animals away from the gate or, alternatively, endanger the human operator). The use of a cable and pulley system reduces the weight of cable and gate on the release rod and makes feasible the use of a quick-acting release rod to effect closure of the gate.

(13) While the present invention has been illustrated by description of several embodiments and while the illustrative embodiments have been described in considerable detail, it is not the intention of the applicant to restrict or in any way limit the scope of the appended claims to such detail. Additional advantages and modifications will readily appear to those skilled in the art. The invention in its broader aspects is therefore not limited to the specific details, representative apparatus and methods, and illustrative examples shown and described. Accordingly, departures may be made from such details without departing from the spirit or scope of applicant's general inventive concept.
