Two-door cage trap with over-center set mechanism
View Patent ↗A cage-type animal trap with two opposed animal access openings that can operate in a one-door-opening configuration or a two-door-opening configuration. The trap has an over-center set mechanism for holding one or both doors open to allow access through the corresponding trap access openings. The set mechanism includes a pivotally mounted set lever coupled to the doors of the trap by an actuating member. A bait pedal is movably mounted inside the trap with a trip rod and link assembly secured to the pedal and to the set mechanism so that when an animal enters the trap, the weight of the animal moves the pedal, causing the trip rod and link assembly to actuate the set mechanism. Upon actuation, the set lever pivots past its over-center position to allow movement of the actuating member which enables one of the doors to move from an opened position to a closed position when the trap is operating in a one-door-opening configuration, and both of the doors to move from the opened position to the closed position when the trap is operating in the two-door-opening configuration.
1. An animal trap comprising:
an animal enclosure having a roof and a pair of opposed animal access openings into a vacant interior sized to receive an animal to be trapped;
a first door movably mounted at a first access opening, the door operative in an opened position to reveal the first animal access opening and in a closed position to block the first animal access opening;
a second door movably mounted at a second access opening, the door operative in an opened position to reveal the second animal access opening and in a closed position to block the second animal access opening;
a first actuating cable having first and second ends, the first end being secured to the first door;
a second actuating cable having first and second ends, the first end of the second cable being secured to the second door;
an over-center set mechanism mounted on the roof of the trap and configured to movably secure the second ends of both of the actuating cables, said set mechanism moving at least said first cable second end toward the second door to open at least said first door when placed in a set position; and
a trip mechanism configured to actuate a pivot action of the set mechanism from the set position toward the first door to reach a tripped position, said pivot action causing the second ends of the actuating cables to move toward the first door and enabling at least the first door to move from the opened position to the closed position thereby trapping the animal in the animal enclosure.
2. The animal trap of claim 1 , wherein said trap is configured to operate as either a one-door-opening trap or as a two-door-opening trap, said trip mechanism initiating closure of both doors substantially simultaneously when the trap is operating as a two-door-opening trap.
3. The animal trap of claim 2 , wherein said trap includes a cable guide mechanism mounted on the roof of the animal enclosure and configured to engage said second cable when said trap is set for two-door-opening operation.
4. The animal trap of claim 3 , wherein said cable guide mechanism is a wire-form hook having an opening facing the first door and a closed face nearest the set mechanism, said second cable entering said opening and being held against said closed face when tensioned between its first and second ends.
5. The animal trap of claim 1 , wherein said set mechanism includes:
a set lever bracket mounted on the roof transverse to a longitudinal direction of the animal enclosure;
a generally U-shaped set lever supported at each end on said bracket so as to be pivotally movable in said longitudinal direction from one side of said bracket to the other side of said bracket, said second ends of said cables being secured to said lever intermediate its bracket-supported ends.
6. The animal trap of claim 5 , wherein said trap is configured to operate as either a one-door-opening trap or as a two-door-opening trap, said trap including a cable guide mechanism mounted on the roof of the animal enclosure and configured to engage said second cable when said trap is set for two-door-opening operation.
7. The animal trap of claim 6 , wherein said cable guide mechanism is a wire-form hook having an opening facing the first door and a closed face nearest the set lever bracket, said second cable entering said opening and being held against said closed face when tensioned between its first and second ends.
8. The animal trap of claim 6 , wherein said trap further includes at least one cable management element mounted on the top of the trap to direct the second cable toward the cable guide mechanism.
9. The animal trap of claim 8 , wherein said trap includes a longitudinally extending handle having handle bases mounted on said set lever bracket, said cable management element including slots formed in said handle bases and extending longitudinally therethrough and in alignment with one another to receive said second cable which passes therethrough.
10. The animal trap of claim 9 , wherein said slots are substantially in longitudinal alignment with a point at which said second cable is secured to the second door.
11. The animal trap of claim 10 , wherein an entry edge of said hook opening is substantially in longitudinal alignment with said slots.
12. The animal trap of claim 11 , wherein an exit edge of said hook opening is substantially in longitudinal alignment with a point at which said second cable is attached to said U-shaped lever.
13. An animal trap comprising:
an animal enclosure having a roof and a pair of opposed animal access openings into a vacant interior sized to receive an animal to be trapped;
a first door movably mounted at a first access opening, the first door operative in an opened position to reveal the first animal access opening and in a closed position to block the first animal access opening;
a second door movably mounted at a second access opening, the second door operative in an opened position to reveal the second animal access opening and in a closed position to block the second animal access opening;
an over-center set mechanism mounted on the roof of the trap and including a pivotally mounted set lever movable between a tripped position and a set position, said lever configured to open at least said first door when placed in said set position;
an actuating mechanism coupled to said set lever so as to be movable therewith and having a first end secured to the first door;
a trip mechanism configured to actuate pivotal movement of the set mechanism lever from the set position to the tripped position to enable at least the first door to move from the opened position to the closed position thereby trapping the animal in the animal enclosure;
said trap configured to operate as either a one-door-opening trap or as a two-door-opening trap depending upon positioning of the actuating mechanism when the set lever is placed in the set position, said trip mechanism initiating closure of both doors substantially simultaneously when the trap is operating as a two-door-opening trap.
14. The animal trap of claim 13 , wherein said actuating mechanism is a cable.
15. The animal trap of claim 13 , wherein said actuating mechanism includes a first cable secured at said first end to said first door and at a second end thereof to said set lever, and a second cable connected at a first end thereof to said second door and at a second end thereof to said set lever.
16. The animal trap of claim 15 , wherein said set mechanism includes a cable guide on the top of the trap for directing the second cable through a 180 change in direction.
17. The animal trap of claim 16 , wherein said trap further includes a longitudinally extending handle having handle bases mounted on top of the trap, said handle bases having respective slots extending longitudinally therethrough and in alignment with one another to receive said second cable.
18. The animal trap of claim 17 , wherein said slots are substantially in longitudinal alignment with a point at which said first end of said second cable is secured to the second door.
19. The animal trap of claim 18 , wherein an entry edge of said cable guide is substantially in longitudinal alignment with said slots.
20. The animal trap of claim 19 , wherein an exit edge of said cable guide is substantially in longitudinal alignment with a point at which said second end of said second cable is attached to said set lever.
