Abstract

Claims (25)

1. A sealing mousetrap comprising:

a housing defining an enclosure to which access is gained through an entrance opening;

a rotatably mounted door for closing the entrance opening;

a door opening and closing mechanism for rotating said door between an open position and a closed position;

a setting/killing mechanism including a setting/killing assembly positioned inside the enclosure for killing a mouse that has entered said housing through said entrance opening, said setting/killing assembly having a set position and a killing position;

a setting member at least partly located outside said housing by which the setting/killing assembly is placed in said set position from outside the enclosure; and

said door opening and closing mechanism being activated automatically to rotate said door to the closed position by movement of the setting/killing assembly to the killing position when the trap is triggered.

2. The mousetrap as set forth in claim 1 , wherein the setting/killing assembly includes a kill bar and a setting bar coupled to a setting axle in a fixed relationship to one another so that said kill and setting bars rotate with said setting axle, said setting member including a handle operatively coupled to the setting axle outside the enclosure, rotation of said handle rotating said setting axle.

3. The mousetrap as set forth in claim 2 , wherein said setting/killing mechanism further includes a trip latch and a bait pedal, both rotatably mounted on the setting axle inside the enclosure and configured to operate together to secure the setting/killing assembly in the set position.

4. The mousetrap as set forth in claim 3 , wherein the trip latch has a triggering tip at one end and a setting hook at an opposite end, said setting hook defining a recess for securing the setting bar in the set position, said bait pedal being mounted above said trip latch and having a cutout through which the triggering tip projects and is caught on an edge of the cutout in the set position, movement of the bait pedal by a mouse releasing the triggering tip to allow the trip latch to rotate and release the setting bar from the setting hook.

5. The mousetrap as set forth in claim 2 , wherein said door opening and closing mechanism includes an axle with an attached lever arm and a spur gear engaged with said axle to be rotatable therewith, said spur gear configured to engage with and rotate a partial pinion gear on said door when said lever arm is rotated, opening the door.

6. The mousetrap as set forth in claim 5 , wherein the setting bar engages the lever arm, causing it to rotate on the axle and, in turn, rotate the spur gear and pinion gear, when the setting bar is moved to the set position by rotation of the setting handle.

7. The mousetrap as set forth in claim 6 , wherein the door includes a door spring that is tensioned when the door is in the open position.

8. The mousetrap as set forth in claim 7 , wherein triggering of the trap from the set position allows the kill bar and setting bar to move rapidly to the kill position, said movement of the setting bar releasing the lever arm, allowing the spur gear to counter-rotate in response to the tensioned door spring which closes the door.

9. The mousetrap as set forth in claim 5 , wherein the bottom of said housing includes a plurality of vertically oriented planar members including an outer member, an inner member and a center member in spaced and generally parallel relationship with one another, said inner and outer members having aligned apertures to receive the door axle upon which the door is supported.

10. The mousetrap as set forth in claim 9 , wherein the spur gear is captured between the inner and center members so as to be generally parallel therewith, said inner and center members having aligned apertures for receiving the axle of the lever arm.

11. A sealing mousetrap comprising:

a housing defining an enclosure to which access is gained through an entrance opening;

a door movable between an open position and a hermetically sealed closed position for closing the entrance opening;

a setting/killing assembly positioned within the enclosure and having a set position and a killing position for killing a mouse that has entered said housing through said entrance opening;

a setting member by which the setting/killing assembly is placed in said set position from outside the enclosure; and

a door opening and closing mechanism for moving said door between said open and closed positions in direct response to placement of said setting/killing assembly in said set and killing positions, respectively.

12. The mousetrap as set forth in claim 11 , wherein the door has a rubber seal that mates with a flange on an inside surface of the housing when the door closes to hermetically seal the enclosure with a dead mouse inside.

13. The mousetrap as set forth in claim 11 , wherein said door opening and closing mechanism includes an axle with an attached lever arm and a spur gear engaged with said axle to be rotatable therewith, said spur gear configured to engage with and rotate a partial pinion gear on said door when said lever arm is rotated, opening the door.

14. The mousetrap as set forth in claim 13 , wherein the setting/killing assembly includes a kill bar and a setting bar coupled to a setting axle in a fixed relationship to one another so that said kill and setting bars rotate with said setting axle, said setting member including a handle outside the enclosure and operatively coupled to the setting axle, rotation of said handle rotating said setting axle, and wherein triggering of the trap from the set position allows the kill bar and setting bar to move rapidly to the kill position, said movement of the setting bar releasing the lever arm, allowing the spur gear to counter-rotate in response to a tensioned door spring which closes the door.
