DETAILED DESCRIPTION OF THE INVENTION

[0061] FIG. 1 is a partly exploded and perspective view of a trap 100 in accordance with various embodiments of the invention and is not meant to be limiting for the scope of the invention. The trap 100 comprises a spring driven, and gas pressure driven killing means 110, a housing 300 with an entrance 310, and a hallway 500 leading to said entrance 310. Here, the spring 160 secures that the piston or spear is retracted after being released/fired by gas propulsion.

[0062] FIG. 2 is a cross-sectional view of a trap 100 in accordance with various embodiments of the invention. The trap 100 is here shown with a piston or spear 200 comprising a smooth cavity 220 with a replaceable core 210 positioned therein. The core 210 may be selected from a kit of cores of varying weights. The weight of the core 210 can be varied by keeping the volume fixed and changing its density, e.g. by providing cores of different material. Alternatively, or in combination, the length or width of the core 210 may be varied. In the shown embodiment, only the length and the density may be varied due to the limitation of the cavity width. It is important that the core 210 is fixed within the cavity 220 since it would otherwise not provide the same impact on a target species when the piston or spear strikes. Furthermore, it may otherwise damage the other components of the piston or spear. Hence, it is advantageous that the piston or spear 200 comprises a cavity 220 adapted for receiving a threaded core 210. The piston or spear 200 is both gas driven, and spring driven. The gas tank 130 (FIGS. 1 and 2) and the spring 160 (FIGS. 2-4) are shown in some of the figures. The piston or spear 200 is activated by the trigger rod 120 and is shown in a retracted position. Apart from the cavity, the piston or spear 200 is preferably made from a polymeric material that is preferably injection mouldable, such as plastic, e.g. polyethylene, polyoxymethylene, or polyethylene. The piston or spear 200 could though be made of metal, such as steel or the like.

[0063] The trap housing 300 (FIGS. 1 and 2) with an entrance 310. An insert 400 is positioned (releasably fastened) within the entrance 310 and in front of the trigger rod 120 and lure/bait housing 150. The intention is that only targeted animals can reach the trigger rod 120. Hence, the insert 400 is adapted for restricting the height and width of the entrance 310, and may be selected from a kit of inserts, each adapted for targeting a specific animal/specie. An example of an insert 400 may be seen in FIG. 5, and may have many different shapes, depending on the shape of the entrance into which it is inserted.

[0064] A further means to reduce non-targeted species is to mount a hallway 500 (FIG. 1) in front of the entrance 310. The hallway 500 is here exemplified with five entry openings 510 (only four may be seen). The entry openings 510 each have a size restricting non-target species from entering the hallway 500, such as larger non-target species, e.g. cats. The entry openings 510 are provided with serrated protrusions 520 to further discourage non-target species form e.g. trying to insert their paws or hands into the entrance 310 via the hallway 500.
