Abstract

A trap for trapping and killing small animals such as rats and mice, is described. The trap comprises a stand, a pivoting clamp, journalled in the stand around a first axis. The clamp may be strained against the action of a spring which may be released by a releasing mechanism from a first, loaded position, when an animal acts upon the releasing mechanism. When released, the clamp immediately swings, acted upon by the spring, to a second position, where it hits and kills the animal. The clamp, extending from the first axis is provided with a first arm and a second arm. A first fastening point of the spring is provided at an end that is turned from the first axis of the first arm. The second fastening point of the spring is provided at the stand. The force line between the two fastening points of the spring runs through or in the vicinity of the first axis such that the spring exerts little or no or torque in the direction towards the second position of the clamp. The trap is primarily characterized in that the releasing mechanism is journalled around the second axis in the stand, forming a first arm portion designed like a cap above a vessel for bait. A second arm portion acts upon the first arm of the clamp when the cap is lifted by the animal.

A trap for trapping small animals, said trap comprising:

a stand;
a pivoting clamp, journalled in the stand around a first axis, for rotatably moving between a first set position and a second released position, said pivoting clamp having a first arm having an axis substantially perpendicular to the first axis, and a second arm having an axis turned from the axis of the first arm;
a spring having one end coupled to the stand and another end coupled to the second arm of the pivoting clamp such that a force exerted by the spring between the ends of the spring passes through a line running through or in the vicinity of said first axis so that the spring applies substantially no torque to the pivoting clamp when the pivoting clamp is in the first set position;
a releasing means, coupled to the stand, for selectively engaging the second arm of the pivoting clamp, such that when an animal acts upon the releasing means, the releasing means moves the pivoting clamp to a position where force exerted by the spring between the ends of the spring passes through a line running away from said first axis so that the spring applies a torque to the pivoting clamp so that the pivoting clamp substantially immediately swings to the second released second position where it hits the animal,
wherein said releasing means further comprises:
a bait holding means for holding bait;
and
a pivoting bait cover, substantially covering the bait holding means and having an arm portion for selectively engaging the second arm of the pivoting clamp, such that when the pivoting bait cover is moved, the arm portion moves the pivoting clamp to a position where force exerted by the spring between the ends of the spring passes through a line running away from said first axis so that the spring applies a torque to the pivoting clamp so that the pivoting clamp substantially immediately swings to the second released second position where it hits the animal.
