Abstract
A mechanical rodent trap has a jaw mounted to a base, with a trigger therebetween which is activated by the incidence of a rodent. An acceleration sensor is mounted in a case in the base in a sensor module that logs and transmit a signal indicating activation of the trap. Alternatively a magnet holder secures a magnet to the trigger, and a Hall effect sensor is used in the sensor module. The sensor modules are sealed within a compartment formed with the base beneath the trigger and closed by a cover.
Claims11
A rodent trap, comprising;
- a plastic base having portions which define a downwardly opening compartment having an upper wall and a downwardly extending side wall;
- a hammer mounted to the base;
- a spring mounted between the hammer and the base;
- a hold-down arranged to retain portions of the hammer spaced from the base, and engaged with a trigger in a set configuration;
- wherein the trigger is mounted to the base above the compartment upper wall and arranged to, when activated by a rodent, release the hold down and to thereby release the hammer, such that the portions of the hammer may strike a rodent on the base;
- a sensor module with a sensor positioned within the base downwardly opening compartment, the sensor being configured to determine activation of the trap, the sensor module having a radio transceiver, a battery, and a microcontroller;
- and
- a cover fixed to the compartment side wall to seal the sensor module within the compartment.

A rodent trap, comprising:
- a base;
- a hammer mounted to the base;
- a spring mounted between the hammer and the base;
- a hold-down arranged to retain portions of the hammer spaced from the base, and engaged with a trigger in a set configuration, wherein
- the trigger is arranged to release the hold down when activated and to thereby release the portions of the hammer to strike the base, the trigger having a plate;
- a magnet mounted to the trigger plate;
- a sensor module with a Hall effect sensor mounted to the base, such that when a rodent engages the trigger and displaces the hold down, the trigger plate pivots downwardly and the hammer is released to move towards the base, and the displacement of the trigger plate downwardly brings the magnet into closer proximity to the Hall effect sensor causing the Hall effect sensor to send a signal which can be logged as a trap activation;
- portions of the base which define a downwardly opening compartment, wherein the sensor module is disposed within said compartment;
- a cover fixed to the base to seal the sensor module within the compartment;
- a plurality of pins which extend downwardly from the compartment upper wall;
- and
- portions of the sensor module which define holes which receive said plurality of pins, the sensor module being thereby fixed in position with respect to the base.

- and
- portions of the cover which define an upwardly protruding peripheral bead which extends between the double peripheral lip.
