FR3078474A1 - NASSE TUNNEL FOR CAPTURING LIVE ANIMALS WITHOUT BODILY DAMAGE - Google Patents

Abstract

The invention relates to a constituent element of a tunnel trap (fig 1). This element consists of a transparent window (3), closing and making impassable, the opposite side to the entrance (4) of the trap. The animal presenting itself at the entrance of the trap, deceived by the presence of the invisible pane, has the illusion of having to deal with a corridor free to the circulation, which has the effect, by deceiving its mistrust, of Encourage him to enter the trap more easily to capture him. Facilitating the capture of live animals without bodily injury is the goal of this invention.

Description

The present invention relates to a device for facilitating the capture of animals and keeping them alive without bodily injury in a trap.

To deceive the vigilance of animals that are reluctant to enter a trap with one access, there are tunnel traps with access to each of the two ends. This configuration is reassuring for the animal, which, once introduced into the device, thinks that it has a double choice to escape: either to turn back, or to flee by the other end

However, these traps have the drawback of requiring a double mechanism actuating the two closing hatches at each end to hold the animal captive.

The device according to the invention makes it possible to preserve the advantages of the two-way tunnel traps, without having the drawback of a double closing mechanism by reducing it to one, and by significantly reducing the length of the trap.

The trap comprising the device according to the invention is a tunnel trap in the shape of a rectangular parallelepiped, the end opposite to the entry into the trap, comprises a transparent pane, which can be anti-reflective, serving as an impassable partition. The interest of a trap made with this device is to deceive the vigilance of the animal, to increase the chances of capturing it, by letting it believe, because of the invisible glass, that it has two exits to choose from to get out or escape in case of danger.

According to a variant relating to the invention, the pane can slide, from top to bottom, between two parallel rows of guides, making it possible to be able to deposit it for cleaning.

£ 0 FIG. 1 represents a perspective view of a tunnel trap fitted with the device according to the invention, suitable for catching small rodents such as rats and mice. This trap is a rectangular grid parallelepiped, about 0.08m wide and high and 0.25m long. The face (3) is made impassable by closing it with a transparent window.

Figure (2) describes in section a mechanism adapted to this trap, in the armed position, controlling the closing of a hatch (8) to hold the animal trapped. It includes four mobile elements (5) (6) (7) and (8):

A step (5) consisting of a board, secured to a rod (6) offset near one side; the assembly articulated around an axis (10) perpendicular to the two sides of the trap. The axis of a hoop (11) integral with the frame supports a rod (7) terminated by a lug engaged in

0 the orifice (12) of the hatch (8) and which retains the latter in the high position. The other curved end is engaged in the loop of (6). A hatch (8) consisting of a rigid plate, ballasted at its base, which can slide between two parallel U-shaped profiles (9).

When the animal enters the trap to access the bait (13), it rests on the step (5) which is hidden under the weight of the animal driving the rod (6) which has for jjF effect release the rod (7) and, ultimately, allow the hatch (8) to fold. The arrows indicate the directions taken by the movable elements during the expansion.

The hatch is limited in its course, to about two millimeters from the bottom of the trap, by a stop, in order to protect the tail of the animals.

A non-return valve, not shown, can, if necessary, come in addition to

4 /) prevent the hatch from being lifted.

The frame (1) supporting the mesh, the rods (6), (7) and the arch (11) are made of rigid steel wires.

Capturing live animals without bodily injury makes it possible, depending on the aim sought, to be able to release them, after a health examination, to band birds, or even in the case of rodents, to release them in a place where they are no longer considered as parasites.

Claims (3)

claims 1) Element of a parallelepipedal tunnel trap, characterized in that it consists of a transparent window (3) closing and making one of the two ends of the trap impassable. 2) window according to claim 1) characterized in that it can slide between two parallel guides to allow it to be deposited. 3) window according to claim 1) characterized in that it is anti-reflective.
