Abstract

The invention relates to a greatly simplified trap which is intended for capturing small animals and which is of the kind in which animals are captured alive without being harmed in any way. The trap (1) comprises a hollow tubular body (2) which is closed at both ends and which preferably has a rectangular cross-sectional shape. At least one of the end openings is closed by means of an inwardly and obliquely extending flap (5, 6; 11) which is hinged to one side of the tubular body (2), preferably to its upper side, and one edge of which rests against an inner surface of the body (2), preferably under the force of gravity. An animal is able to enter the trap by pushing against the flap, such as to raise the flap or to move it to one side. Subsequent to the animal having passed the flap, the flap will return to its original starting position, thus imprisoning the animal in the trap.

Description

A DEVICE FOR CAPTURING SMALL ANIMALS

TECHNICAL FIELD

The present invention relates to a device for capturing small animals alive, wherein the captured animal is impris¬ oned in a closed space, normally without suffering injury. This device is hereinafter referred to as a small-animal trap.

BACKGROUND PRIOR ART

Small-animal traps of this kind were used long before pres¬ ent records began, and have become progressively more re- fined and effective as new techniques have developed and new materials have been devised. The majority of traps are intended to kill the animals captured, for instance by drowning strangulation or by electrical shock. Those traps which are intended to capture animals alive normally have some form of baited tilt board onto which the animal is lured and which, when the animal touches the bait, is released and tilts rapidly, therewith causing the animal to fall down into a cage or some similar underlying space. itlv some traps of this kind the tilt board is returned to its original position through the medium of a counterweight system, such as in the trap described in Swedish Patent Specification No. 32 363, whereas other traps must be re¬ set, as in the case of the trap described in Swedish Patent Specification No. 46 093. Λ common fault with the majority of traps intended for capturing small animals alive resides in the mechanism by means of which the tilt board or like device is latched when baiting the trap. This mechanism is of a more or less complicated construc¬ tion and renders the trap expensive and complicated to manipulate. Since the cages of many traps of this kind have the form of a metal net structure, it has been neces¬ sary to provide those traps which are intended for captur- ing predatory animals with a handle or the like, so that the trap can be carried safely without danger of the trap¬ per being bitten. A further complication with known traps is that they must normally be provided with a special re- lease flap or trap door through which the animal can be re¬ leased from the trap, since it is difficult to remove the animal through the trap entrance.

SUMMARY OF THE INVENTION

The object of the present invention is to provide a small- animal trap which is intended for capturing small animals alive and which overcomes the aforementioned drawbacks, and with which trap the need for a latching mechanism and a special release flap or trap door is eliminated, thereby rendering the trap easier to manufacture. This and other objects are achieved by means of an inventive small-animal trap which has the characterizing features set forth in the following claims.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention will now be described in more detail with reference to exemplifying embodiments thereof illustrated in the accompanying drawing, in which

Figure 1 is a partially cut-away side view of the end parts of a trap which is provided with two flaps and which has the form of a tube of rectangular cross-section;

Figure 2 is a perspective view of a trap which comprises a conical tube of rectangular cross-section and which has a flap arranged in the wider end of said tube; and

Figure 3 illustrates a flap both in side view and in plan. DESCRIPTION OF PREFERRED EMBODIMENTS

Figure 1 illustrates schematically and in partially cut¬ away side view a small-animal trap 1 which is constructed in accordance with the invention and which comprises a trap body in the form of a tube 2 of rectangular cross-sec¬ tion, the two end openings 3, 4 of which tube are closed by means of respective hinged flaps 5 and 6, the lengths, or vertical extensions, of which are greater than the vertical extension of their respective opening, such that the flaps are inclined and extend obliquely towards the centre of the tube 2. Each of the flaps 5, 6 of the illustrated embodi¬ ment comprises one half of a respective hinge, the other halves 7, 8 of which are secured to the wall of the tube 2 in the proximity of a respective end opening 3, 4. The two flaps 5, 6 are held in their inclined, trap-closing posi¬ tion under the influence of their own weight, i.e. gravita- tionally, and the predators enticed into the trap by the scent of the bait placed therein themselves lift away the flap concerned, which falls back to its original starting position once the animal has passed by the flap. Since the animal is unable to lift the flap from inside the flap, in order to escape, the animal remains trapped in the trap.

Figure 2 is a perspective view of a trap which comprises a body in the form of a conical tube 9 of rectangular cross- section, the wider end 10 of which tapering tube has a flap 11 arranged therein, and the narrow end of which is closed by a wall 12. This trap is produced by injection molding, preferably from a transparent acryl or styrene resin. The possibilities afforded by injection molding techniques en- able the flap hinge mechanism to be made extremely simple. As illustrated in Figure 3, the flap 11 may be molded in one piece together with hinge pins 13, 14. Slots 15, 16 which correspond to the hinge pins are formed in the walls defining the opening at the wide end 10 of the tube 9, these slots terminating in a respective circular recess 17, 18. The hinge pins 13, 14 which are half cylindric have each one side that extends mainly parallel with the flap and are so dimensionedtha when the flap is positioned so as to extend along the upper inner surface of the tube 9 said pins can be pressed along the slots 15, 16 and into respective recesses 17, 18, in which said hinge pins are freely rotatable. The fact that the flap 11 can be fitted so easily into the tube 9 enables the trap to be sold as a kit assembly comprising two parts which can be easily assembled by the user. This greatly facilitates transportation and storage of the traps. The conical configuration of the traps or tubes enables them to be partially inserted one into the other prior to fit¬ ting the flaps 11, whereby the space required to store and to transport the inventive trap is far smaller than that required in the case of corresponding conventional traps.

A further advantage afforded by the inventive trap resides in the ease with which the captured animal can be released. Thus, the trap is simply rotated through 180 about its longitudinal axis, such as to cause the flap 11 to lie against the new unclersur ace and thereby expose the opening at the wide end 10 of the trap-.

It will be understood that the trap is not restricted to the illustrated embodiments and that modifications can be made within the concept of the invention. For example, the flap 11 can bo placed on any desired side of the tube 9, although it is then, of course, necessary to use a spring or corresponding means to return the flap to its original position once the animal entering the trap has passed by the flap.
