DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a hunting trap device, wherein a spring-tensioned arm is adapted to move, when in released state, across an opening forming the entrance to the trap, and wherein a trigger means for the arm is disposed at the opening inside the trap, wherein the opening is oval or circular and is formed in both a front wall and a partition positioned therebehind, wherein the axis of rotation of the arm is located at a level below the lower edge of said opening, and wherein the arm is adapted to move in an intermediate space between the front wall and the partition.
BACKGROUND OF THE INVENTION
The device is particularly suitable for a killing trap in which bait is used, primarily for killing fur-bearing game, e.g., martin or mink; but it may also be dimensioned for all types of game, e.g., up to the size of lynx, depending on the proportions of the trap.
From the prior art there are known many types of hunting traps, all having in common the feature that the game animal is destroyed in a less than satisfactory manner, often involving considerable pain for the quarry. This causes problems and inefficiency in the practical hunting process. A number of difficulties are also associated with the freezing solid of the trigger mechanism and striking device when the weather changes from sleet, rain and thaw to frost and extreme cold. Another problem, perhaps equally serious for hunters in certain years, is that mice and lemming may eat up the bait before the intended game approaches the vicinity of the hunting trap. It is also difficult for the hunter to manage to fasten the bait at the correct distance from the striking device so that said device will strike in the right place and thus produce a prompt and effective execution without any notable pain for the animal.
With regard to liquid bait, it has been fruitless up to now to use this type of bait for anything other than a luring means.
There has for a long time been a desire among hunters to utilize a hunting trap that is equipped with bait, and which functions perfectly under all operating conditions, including when it is covered with snow or submerged in water. From U.S. Pat. No. 4,425,732 there is known a solution which utilizes a straight, striker spring arm having a short stroke length, and where the entrance opening to the trap is flat at the bottom. There is a danger with this type of solution that the animal will be pushed to the side of the opening before the arm locks the animal in the trap. With this known solution there is, in fact, a risk that the animal will be gradually strangled instead of being promptly put to death. This risk has been determined by trappers on the basis of their observation of the formation of foam around the animal's mouth, which would confirm that the animal evidently had been alive after the trap was sprung.
SUMMARY OF THE INVENTION
In the light of the fact that the known hunting traps, including the type disclosed in U.S. Pat. No. 4,425,732, inflict needless suffering on the animal when it is killed, the intention of the present invention is to provide a hunting trap device of the type described in the above introduction, which device is characterized, according to the invention, in that the arm is arcuate over a substantial portion of its length, with a curvature oriented opposite to the curvature at the bottom of the opening in the hunting trap when the arm moves across said opening, the curved arm in its released, downward striking state capable of hitting and breaking the neck or spine of an animal located in said opening and lock the animal against said curved bottom of the opening, and that the arm in its released, striking state with said opening unobstructed by an animal is able to move down across said opening and past the lower edge of the opening.
According to one embodiment form of the device, the arm is, in a manner known per se, an integral part of a striker spring, where one free portion of the spring forms the arm and the other free portion forms abutting contac
