Claims
- 1. A trapping mechanism for a mousetrap, said mechanism comprising an anchor plate having depending end walls each formed with a lower edge, a striker plate to fit over the anchor plate, the striker plate having depending walls to fit outside the end walls of the anchor plate, the end walls of the striker plate being deeper than the end walls of the anchor plate and each having an aperture therein with a bottom edge spaced below the lower edge of the respective anchor plate end wall to form a trapping aperture therebetween, a spring to be fitted between the plates and provide a force urging the striker plate upwardly with respect to the anchor plate into a sprung position wherein said bottom edges of the striker plate apertures approach the respective lower edges of the anchor plate end walls and wherein the striker plate can be pushed down against said force into a set position wherein said bottom edges are removed from said lower edges, and a trigger assembly carried by the anchor plate for releasably holding the striker plate in the set position wherein the trigger assembly comprises a trigger pivotally mounted in an aperture in the anchor plate, said trigger having a mouse engaging portion extending below the anchor plate between the anchor plate end walls and a catch portion projecting above the anchor plate, the striker plate including an opening to receive the catch portion of the trigger and having one edge to engage and retain the catch portion in the set position of the mechanism.
- 2. A trapping mechanism as claimed in claim 1, wherein the trigger assembly comprises a trigger pivotally mounted in an aperture in the anchor plate, said trigger having a mouse engaging portion extending below the anchor plate between the anchor plate end walls and a catch portion projecting above the anchor plate, the striker plate including an opening to receive the catch portion of the trigger and having one edge to engage and retain the catch portion in the set position of the mechanism.
- 3. A trapping mechanism as claimed in claim 1, wherein the opening in the striker plate is covered by an enclosure for preventing the trigger from being inadvertently released from above.
- 4. A trapping mechanism as claimed in claim 1, wherein the mouse engaging portion of the trigger includes bait attachment means.
- 5. A trapping mechanism as claimed in claim 4, wherein the bait attachment means comprises gripping means for a sunflower seed.
- 6. A trapping mechanism as claimed in claim 5, wherein the trigger includes a vertically extending arm and the gripping means includes a foot treadle at a lower end of said arm and a hook on the arm above the treadle for gripping a sunflower seed between the treadle and the hook.
- 7. A trapping mechanism as claimed in claim 6, including a seed-receiving notch in the treadle and a projecting stop on the treadle adjacent the notch.
- 8. A trapping mechanism as claimed in claim 5, wherein the trigger is impregnated with a mouse-attracting scent.
- 9. A trapping mechanism as claimed in claim 1, wherein the trigger is mounted on a pivot axle extending perpendicularly to the end walls of the anchor plate and wherein a second spring is provided around the axle for urging the trigger toward the set position wherein the catch portion engages said one edge of the opening in the striker plate.
- 10. A trapping mechanism as claimed in claim 1, including a guide flange for the striker plate extending upwardly from the anchor plate to engage and guide one edge of the striker plate when the mechanism is sprung preventing tilting of the striker plate tending to jamb the mechanism.
- 11. A trapping mechanism as claimed in claim 10, wherein the guide flange has vertical ribs engaging said edge of the striker plate.
- 12. A trapping mechanism as claimed in claim 1, in combination with a tunnel having a top wall with an aperture to receive said trapping mechanism wherein the anchor plate includes securing means for securing same to the tunnel substantially flush with said top wall with said anchor plate end walls projected into the tunnel.
- 13. A trapping mechanism as claimed in claim 12, wherein the securing means comprises tabs extending downwardly from the anchor plate on opposite edges of the anchor plate, said tabs gripping side walls of the tunnel defining said aperture therebetween.
- 14. A trapping mechanism as claimed in claim 1 wherein the spring comprises a coil spring.
