Description

The invention relates to means for capturing small animals and can be used to capture mice, rats, ferrets and other animals.

Known mousetrap for catching small animals, in particular rodents (patent RU 2073434, ⁶ A01M 23/04, ⁶ A01M 23/08, ⁶ A01M 23/14, publ. 02.20.1997), containing located in the housing compartment for bait, an input chamber with a two-sided swinging platform and a storage chamber. Between the inlet and the accumulation chambers there is a one-way valve connected to the swinging platform by means of a clamp. The latch is made in the form of a lever with horizontal and vertical shoulders connected by a horizontal swing axis with a counterweight. The valve is made in the form of a two-shouldered lever with a right or obtuse angle between the shoulders and the horizontal axis at the apex, equipped with a fuse, also made in the form of a two-shouldered lever, freely fixed on the horizontal axis of swing under the smaller horizontal arm of the valve. The smaller arm of the fuse is equal to the vertical distance between the swing axes of the valve and the fuse.

Also known are traps with a swinging body made in the form of a container in which the captured animal remains alive and unharmed.

Such traps include a well-known trap containing an elongated open at one end of the body with a central support or curved bottom wall, allowing the body to swing under the influence of the weight of the animal (patent application RU 94040448 A1, A01M 23/16, publ. 10.09.1996). To the upper part of the housing, close to the inlet, a falling shutter is pivotally attached, made with uprights for supporting on a supporting surface. In the guarded position of the trap, the shutter is open and the animal attracted by the bait can enter the body. Under the influence of the weight of the animal approaching the bait, the body rotates relative to the central support, and the bolt with uprights rotates relative to the hinge. The shutter closes the inlet of the housing, preventing the exit of the animal, and in this position is held by a ledge attached to the housing.

Another known trap contains a housing with an inlet and a door for blocking the inlet (patent US 4578892 (A), A01M 23/18, A01M 23/20, A01M 23/22, publ. 01.04.1986). The housing consists of two rectangular compartments interconnected at an obtuse angle. A door pivotally attached to the upper part of the housing by means of an axis is provided with a latch or magnet for engaging with the housing. In the guarded position of the trap, the body rests on the first compartment from the inlet and can rotate relative to the top of the obtuse angle under the influence of the weight of the animal, and the door rests on the abutment surface.

Also known is a trap for small animals, containing a housing with an inlet, upper, lower and side walls, a falling bolt and support (US patent 1581297 (A), A01M 23/20, published on 04.20.1926). A through groove is made in the upper wall of the housing near the inlet. In the side walls of the housing, vertical through grooves are made with an expanded section in the lower part. The falling shutter is made in the form of a flat plate, to the lower part of which a rod is attached. The ends of the rod protrude beyond the lateral edges of the plate, are inserted into the vertical grooves of the side walls of the housing and protrude outward from the side walls of the housing. The support is mounted on the bottom wall of the housing.

The closest is, selected as a prototype, a trap for small animals, containing a housing with an inlet, upper and lower walls, a falling shutter and support (patent US 4744170, A01M 23/20, publ. 05.17.1988). The body is curved in an arc so that its lower convex wall serves as a support, allowing the body to swing under the influence of the weight of the animal. The upper wall of the body is solid. A frame is installed in front of the housing inlet containing side walls and a lower wall. In the side walls of the frame, vertical guides are made on the inside for moving the falling shutter along them and fixing the falling shutter in the upper and lower positions. The falling shutter contains a flat plate on which the load, the handle and two hooks are located to hold the falling shutter in the upper position.

In this trap, the moment the shutter is set in motion when the housing is rotated depends on the angle of the falling shutter relative to the vertical guides and the state of the sliding friction surfaces in two nodes, which reduces the reliability of the trap. In addition, the trap is structurally complex.

The objective of the invention is to create a structurally simple and reliable working trap with a falling shutter.

The technical result achieved by the present invention is to constructively simplify the trap with a falling shutter while increasing reliability.

The specified technical result is achieved in that the animal trap comprises a housing with an inlet, upper and lower walls, a falling shutter and a support. A through groove is made in the upper wall of the housing to accommodate the falling shutter in the open position, moving along the through groove of the falling shutter under its own weight from the open position to the closed position, and holding the falling shutter in the closed position. Between the inlet and the through groove is a slope for holding the falling shutter in the open position, automatically releasing the falling shutter and free sliding from the slice when the housing is rotated around the support. The falling shutter is L-shaped and contains a stop resting on the upper wall of the housing in the closed position of the falling shutter to prevent the catch from opening.

The shutter can be made of sheet material with the possibility of plastic deformation to change the start of movement of the falling shutter from the open position to the closed position when the body is tilted.

The housing may be made of sheet material.

A longitudinal groove may be formed on the bottom wall of the housing. The support is inserted into a longitudinal groove with the ability to move along the longitudinal groove and lock in a selected position.

The support can be made of sheet material with the possibility of plastic deformation to change the height of the support.

All details of the trap are structurally simple and can be made by cutting geometrically simple blanks from the same sheet material, followed by bending along straight lines. In this case, the housing can be made in the form of a rectangular parallelepiped, open from the front end and closed from the rear end.

The trap can be made using structurally simple cutting and bending equipment. As the sheet material, it is preferable to use a steel sheet with a polymer coating, galvanized steel sheet, duralumin, aluminum, other metal.

In the alert position of the trap, the center of gravity of the shutter is located above the slime. The shutter rests its weight on the skliz. When the housing is rotated at the moment the trap is triggered, the center of gravity of the shutter is shifted to the through groove made in the upper wall of the housing. In the position above the through groove, the center of gravity of the shutter creates a tilting moment, under the influence of which the shutter tilts and under the action of the increasing tilting moment freely slides from the slice and falls, closing the inlet of the housing. In the closed position, the shutter lays with its emphasis on the upper wall of the housing, preventing the animal from being caught open.

The reliability of the trap is increased due to the execution of the shutter L-shaped, the location of the shutter in a wary position on the slope and reduce friction that keeps the shutter from moving.

The invention is illustrated in the drawing, which shows:

The animal trap comprises a housing 1 with an upper 2, lower 3 and rear 4 walls and an inlet 5, a support 6 fixed to the lower wall 3 of the housing 1, and a falling shutter 7 with a leading edge 8. The falling shutter 7 is made in the form of an autonomous part. A through groove 9 is formed in the upper wall 2 of the housing 1, which is configured to hold the leading edge 8 of the falling shutter 7 in it in the open position, to freely move along the through groove 9 of the falling shutter 7 under its own weight when the housing 1 is tilted and the falling shutter 7 is held in closed position. The upper wall 2 of the housing 1 is made with the possibility of placing the falling shutter 7 in the open position with the center of gravity 10 of the falling shutter 7 between the inlet 5 and the through groove 9. The housing 1 is made of sheet material, the opposite edges 11 and 12 of which are fastened to the lower wall 3 the housing 1 with the formation of a longitudinal slit between them 13. The falling shutter 7 is equipped with a stop 14, resting on the upper wall 2 of the housing 1 to prevent the opening of the caught animals. The support 6 is made of sheet material with the possibility of plastic bending to change the height of the support 6 and is equipped with a shank 15 for placement in the longitudinal slot 13 of the lower wall 3 of the housing 1 with the possibility of movement along the longitudinal slot 13 and fixation in a selected position. The trap can be mounted on a horizontal 16, inclined 17 or uneven surface with a bait 18. Between the inlet 5 and the through groove 9 there is a slit 19 for holding the falling shutter 7 in the open position and automatically releasing the falling shutter 7 and free sliding from the slider 19 when located the center of gravity 10 of the shutter 7 above the through groove 9.

When installing the trap in a wary position on a horizontal surface 16, the support 6 is located under the middle part of the housing 1. The bait 18 is placed in the housing 1 at the rear wall 4. The falling shutter 7 in the open position is installed on the slide 19 so that its front edge 8 is in through the groove 9, and the center of gravity 10 of the falling shutter 7 was located above the slime 19, as shown in the drawing (figure 1).

The animal, attracted by the smell of the bait 18, enters the housing 1 through the inlet 5 and, approaching the bait 18, with its weight rotates the housing 1 around the support 6 to the position shown in the drawing (Fig. 3). The center of gravity 10 of the falling shutter 7 moves to the through groove 9. When the center of gravity 10 is located above the through groove 9, the leading edge 8 of the falling shutter 7 is released from contact with the housing 1. The falling shutter 7 rotates in the same direction as the housing 1, tilts to slide 19 and slides freely from slide 19. Moving along the through groove 9 under the action of its own weight, the falling shutter 7 closes the inlet 5. The stop 14 rests on the upper wall 2, preventing the opening of the falling shutter 7 of the caught animal.

When installing the trap in a guarded position on an inclined 17 or uneven surface, adjust the trap by moving the support 6 along the longitudinal slit 13 with the shank 15 fixed in the selected position by the edges 11 and 12 of the sheet material elastically pressed against each other. Additionally, the trap is adjusted by plastic bending or extension of the support 6 and the falling shutter 7. In the adjusted position, the trap can be mounted on an inclined 17 or uneven surface in the position shown in the drawing (Fig. 5).

The simplicity and simplicity of the trap manufacturing, the reliability of operation and the possibility of regulation to ensure reliable operation in different operating conditions expand the scope of the trap.

The trap is at the same time a convenient portable container for the caught animal.
