Abstract
The trap (42, 82) is based around a spring mechanism (24, 60) comprising a substantially rectangular sheet of spring material folded to be substantially C-shaped in cross-section. In one embodiment (FIG. 6), portions (64, 65) of the spring mechanism (60) are adapted to be killing surfaces. In another embodiment FIG. 2), the spring mechanism (24) is provided with arms (28, 29) that support jaws (36, 37). A setting mechanism (53/54, 77) holds the spring mechanism (24, 60) in an armed position and the trap (42, 82) is triggered when a trigger mechanism (49, 75) is moved by an animal which in turn disengages the setting mechanism (53/54, 77) and allows the killing surfaces (portions 64, 65) or jaws (36, 37) to come together on the animal therebetween.
Claims23
A single kill animal trap comprising:
- a spring means comprising a substantially rectangular sheet of spring material folded transversely to be substantially C-shaped in longitudinal cross-section defining an upper surface, a lower surface and a back wall;
- whereby said upper surface and said lower surface are biased together, and further wherein a portion of each of the upper surface and the lower surface is adapted to be a killing surface in use;
- a setting means adapted to hold the upper and lower surfaces in an armed position;
- and
- a trigger means positioned within the space defined by the upper and lower surfaces and the back wall of the spring means and co-operable with said setting means;
- the trap being triggered when the trigger means is moved by an animal which in turn disengages the setting means allowing the killing surfaces to come together on a said animal therebetween.
A single kill animal trap comprising:
- a spring means comprising a substantially rectangular sheet of spring material folded transversely to be substantially C-shaped in longitudinal cross-section describing an upper surface, a lower surface and a back wall;
- upper and lower pairs of arms projecting from the back wall of the spring means;
- upper and lower jaws affixed to upper and lower arms respectively, said jaws biased together by the spring means;
- a pivot support frame comprising an elongated rod engaging and extending upwards from each lower arm adjacent the lower jaw and a cross-piece connecting the upper ends of said rods;
- a pivot rod pivotally mounted on the cross-piece, the end of the pivot rod extending away from the back wall beyond the cross-piece to form a jaw rest, the other end of said pivot rod extending above the upper surface in the direction of said back wall;
- and
- trigger means positioned within the space defined by the upper and lower surfaces and the back wall of the spring means, said trigger means engaging a connecting rod that engages a pivot rod;
- the trap being armed when the upper jaw is pivoted to be engaged on the jaw rest and the other end of the pivot rod is retained by the connecting rod, trigger bar and catch;
- and being triggered when the trigger bar is released from the catch.
