Description

The present invention relates to an animal trap, and more particularly to an animal trap for tying a string to an animal leg.

Conventionally, in order to capture an animal, an animal trap for tying a string-like body to the leg of the animal has been used.
As such an animal trap, in a trigger device installed on the ground surface and equipped with a wire for tying the legs of animals, the semi-annular first band and the second band connected to each other are composed of these. A wire mounting body that can be rotated at the connecting portion of the above, a support rod that is fitted to the inner circumference of the first band body and the second band body, and a tread plate that is placed on the support rod are provided, and further, the first It has been proposed to provide a notch recess in the center of the band and the second band in the longitudinal direction, and to arrange a support rod on the upper part of the notch recess (Patent Document 1).

Japanese Unexamined Patent Publication No. 2018-57289

However, in the trigger device of Patent Document 1, since the tread plate that triggers the operation is simply mounted on the support rod fitted to the inner circumference of the first band body and the second band body, the tread plate is provided. If it is displaced from the proper position, even if the beast steps on the tread, the force to press the support rod and remove it from the notch recess will escape, and there is a risk that it will not operate properly.

It is an object of the present invention to provide an animal trap that can improve the certainty of movement when stepped on by an animal.

(1 An animal trap for tying a string around an animal's leg.
A frame body having an opening at least above, formed in a ring shape, and around which the string-shaped body formed in a ring shape is wound.
Inside the frame, a plate-shaped body that is swingably arranged is provided.
The frame body is composed of a plurality of frame members, has a notch formed on the lower side in the height direction, and has a rotation axis extending in a direction substantially parallel to the opening, with respect to one of the frame members. The other frame member is rotatable and can be rotated.
The upper surface of the plate-shaped body faces the opening, and the shaft member is fixed to the lower surface.
The shaft member extends from one frame member toward the other frame member in a direction substantially parallel to the lower surface.
Each of the frame members is provided with an engaging portion on the inner surface side thereof , which projects inward above the notch and engages with the upper portion of the end portion of the shaft member.
The engaging portion is inclined downward from the central portion toward the end portion when viewed from the inside of the frame member.
In the initial state where the frame is not rotated,
The string-shaped body urged in a direction in which the inner diameter of the ring becomes smaller is wound around the frame body.
Both ends of the shaft member are provided below the engaging portions when the upper portions of the shaft members are engaged with the engaging portions of the plurality of frame members and the upper surface of the plate-shaped body is stepped on by an animal. Movable towards the notch that was made,
When the upper surface of the plate-shaped body is stepped on by an animal, the end portion of the shaft member comes to the position of the notch, so that the engagement portion between the engaging portion and the end portion of the shaft member is released, while the engagement portion is released. An animal trap characterized in that the other frame member rotates with respect to the frame member, the string-shaped body is detached from the frame body, the inner diameter of the ring is reduced, and the legs of the animal are tied up.

According to the configuration of (1), the trap for catching an animal is provided with a frame body and a plate-shaped body by winding a string-shaped body around the legs of the animal.
The frame has an opening at least above and is formed in a ring shape, and a ring-shaped string-shaped body is wound around the outer periphery.
The plate-shaped body is arranged so as to be swingable inside the frame body.
Further, the frame body is composed of a plurality of frame members, and the other frame member can rotate with respect to one frame member about a rotation axis extending in a direction substantially parallel to the opening.
The upper surface of the plate-shaped body faces the opening, and the shaft member is fixed to the lower surface.
The shaft member extends from one frame member toward the other frame member in a direction substantially parallel to the lower surface.
Each of the plurality of frame members is provided with an engaging portion that engages with the upper portion of the end portion of the shaft member.
In the initial state in which the frame body is not rotated, the animal trap is wound around the frame body with a string-like body urged in a direction in which the inner diameter of the ring becomes smaller.
Further, both ends of the shaft member are engaged with the engaging portions of the plurality of frame members, respectively, and when the upper surface of the plate-shaped body is stepped on by an animal, the engaging portion and the end portion of the shaft member are engaged. The mating is released, the other frame member rotates with respect to one frame member, the string-shaped body comes off from the frame body, the inner diameter of the ring becomes smaller, and the animal's leg is tied.

As a result, since the shaft member for maintaining the plurality of frame members in the initial state is fixed to the plate-shaped body that triggers the operation of the animal capture trap from the initial state, the plate-shaped body and the shaft member are displaced from each other. When the plate-shaped body is stepped on by an animal, the force due to the stepping can be appropriately transmitted to the shaft member. Further, since the plurality of frame members are provided with an engaging portion that engages with the upper portion of the end portion of the shaft member, the shaft member does not come off upward in the initial state, and the initial state is maintained in a more appropriate state. Since it can be done, the certainty of operation is improved.
Therefore, it is possible to provide an animal trap that can improve the certainty of movement when stepped on by an animal.

Further, the shaft member is engaged with the engaging portion inside the frame body, and unlike the trigger device of Patent Document 1, screwing between the shaft member and the frame body is unnecessary, which is dangerous in handling. There are few. Further, when setting the animal trap, it is only necessary to engage (put) the end portion of the shaft member with the engaging portion and invert the entire animal trap, which facilitates the work.

According to the configuration of (2), since the engaging portion that engages with the upper portion of the end portion of the shaft member is inclined downward from the central portion toward the end portion on the plurality of frame members, the shaft member is in an initial state. When the plate-like body is stepped on by an animal without coming off laterally, the end of the shaft member is guided by the engaging part and the engagement is released, so that in a more appropriate state, It becomes possible to operate.

According to the present invention, it is possible to provide an animal trap that can improve the certainty of movement when stepped on by an animal.
