However, in such a conventional vermin catching tool, it takes a long time for the catching wire to reduce the diameter via the spring when the vermin steps on the tread plate. The reason is that the structure of the interlocking mechanism from the operation of the tread plate to the diameter reduction operation of the capture wire is structurally complicated, and the number of parts of the interlocking intermediary mechanism intervening between them is large.

INDUSTRIAL APPLICABILITY The present invention provides a vermin catching tool configured to be able to reduce the diameter of a catching wire in the shortest distance and the shortest time in spite of its simple structure.

In the present invention, a tubular base having side walls raised on the peripheral edge, a semi-arc-shaped left and right wire holders having both ends pivotally supported on the side walls of the tubular base and erected on the left and right sides, and lodging of the left and right wire holders. In the state, the loop part of the capture wire that surrounds the semicircular outer peripheral surface of the left and right wire holders, and the wire diameter reduction urging mechanism that pulls the base of the loop part of the wire that surrounds the left and right wire holders to reduce the diameter of the loop. It is intended to provide a pest catching tool characterized by being composed of.

Further, the wire diameter-reducing urging mechanism includes a wire guide member that inserts and guides both free ends of the wire, which is the loop base of the loop-shaped wire, and a wire guide member that is arranged on the lower side of the guide member and extends from the loop base. The two wire insertion pipes through which the book wires are inserted and the wire in contact with the opening base ends of the two wire insertion pipes can be freely pulled in the tension direction and fixed at that position, and the wires can be loosened in the relaxation direction. It consists of a stopper function member with a wire one-way function that can be used, and a winding spring that surrounds the outer circumference of the wire in each of the two wire insertion pipes and is compressed and interposed between the stopper function member and the wire guide member. It is characterized by that.
Further, the stopper function member is housed in an outer cylinder and an outer cylinder formed on an inner peripheral surface having a tapered surface that expands in the pulling direction of the capture wire whose diameter of the loop portion is reduced, and the capture wire is inserted into the cylinder. An inner cylinder having a plurality of ball insertion holes formed in the peripheral wall of the cylinder, and a plurality of balls arranged in the plurality of ball insertion holes between the inner peripheral surface of the outer cylinder and the outer peripheral surface of the capture wire. A plurality of balls come into contact with the tapered surface of the outer cylinder as the loop portion expands in diameter, and the balls are displaced toward the center of the inner cylinder to pinch the capture wire between the balls. It is characterized in that the wire and the stopper function member are integrally fixed so as to perform the stopper function.
The two wire insertion pipes may be integrally housed in a tubular outer case.

According to the invention of claim 1, both ends are pivotally supported on a cylinder base, and a semicircular left and right wire holders are provided in which the left and right sides are erected and urged. Since the surface is surrounded by the loop part of the capture wire, when the left and right wire holders stand up due to the operation of the tread plate, the capture wire will be flipped up at the same time as the left and right wire holders stand up, and the legs of the beast will be instantly lifted. It has the effect of being able to be captured.
Furthermore, since the loop portion forming operation and the loop diameter reduction operation of the capture wire are performed by the wire diameter reduction urging mechanism arranged on the outer side of the cylinder base, the operation structure of the capture wire is simplified and the vermin capture function is performed. Has the effect of being able to improve.

Further, in the wire diameter shrinking urging mechanism, both free ends of the capture wire forming the loop portion are inserted into two wire insertion pipes, and both free ends are pulled and urged by their respective winding springs to contract the loop portion. Since it is configured to perform diameter operation, one wire free end is fixed and only one of the other free ends of the loop part is pulled and urged, which is half the time and stress compared to the conventional loop diameter reduction structure. Since the diameter of the loop portion can be reduced and the trapping operation can be performed quickly, there is an effect that the certainty of the trapping can be improved.

Examples of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows an overall explanatory view of the present invention.

The vermin catching tool A of the present invention is provided with a substantially elliptical tubular base 2 having a peripheral wall 1 having a constant height.
Both ends of a strip-shaped left and right wire holder 3 having a semicircular constant width are pivotally supported at positions facing each other on the peripheral wall 1 of the tubular base 2.

The left and right wire holders 3 are formed in a semicircular shape, and when the left and right wire holders 3 are laid down around the pivots 4, the coil springs 5 are stretched over the pivots 4 and the bases of the left and right wire holders 3 so that they are not always horizontal. The left and right wire holders 3 are urged to stand up by the coil springs 5 by interposing them.

The capture wire a having a trap function in a substantially horizontal state in which the left and right wire holders 3 are laid down against the bias is brought into contact with the outer surface of the band of the left and right wire holders 3 at the loop portion a ”. Surrounding the semi-arc-shaped outer surface 3'of the left and right wire holders 3, both free ends of the capture wire a, that is, the loop bases, join at the position of one pivot 4 of the left and right wire holders 3, which will be described later. It is connected to the wire diameter reducing urging mechanism b.

In such a configuration, a tread plate 6 having substantially the same shape as the cylinder base 2 is attached to the upper edge opening of the cylinder base 2.
That is, the tread plate 6 is loosely fitted inside the substantially horizontal left and right wire holders 3 and mounted horizontally. In particular, the left and right wire holders 3 having a semicircular arcuate outer peripheral surface of the peripheral side wall 6'of the tread plate 6 It is fitted so as to abut and engage with the lower edge of the outer surface of the band.
That is, as shown in FIG. 1, the left and right wire holders 3 are substantially horizontal and left and right open, and the tread plate 6 is fitted inside the left and right wire holders 3 on the outer surface of the peripheral side wall 6'of the tread plate 6. The lower edge portion of 3 comes into contact with each other to enter a crimp engagement state. The tread plate 6 keeps the left and right wire holders 3 in a horizontally open state along the cylinder base 2 against the urging force of the coil springs 5.

The leg capture mechanism of the vermin is configured by the three members of the tread plate 6, the left and right wire holders 3, and the loop-shaped capture wire a that is contact-held on the outer peripheral surfaces of the left and right wire retainers 3.
That is, in such a capture mechanism, when the leg of the vermin steps on the tread plate 6, the tread plate 6 is lowered and the engagement with the left and right wire holders 3 is disengaged. As a result, the horizontally open form of the left and right wire holders 3 that hold the capture wire a in a loop is eliminated, and the left and right wire holders 3 stand up and operate by the urging of the coil springs 5. The loop portion a "of the capture wire a wound and supported around the outer periphery of the left and right wire holders 3 is also lifted by the left and right wire holders 3 at the same time to quickly surround the legs of the vermin as shown in FIG.

At the same time, the regulation of the left and right wire holders 3 is released from the loop portion a "of the capture wire a", and the free end of the capture wire a is pulled by the wire diameter-reducing urging mechanism b described later to form the loop portion a ". The diameter is reduced to capture the legs of the vermin.

Next, the wire diameter-reducing urging mechanism b for tension-operating the capture wire a having the loop portion a "formed by FIGS. 3 to 6 will be described. That is, the left and right wires are held on the peripheral side wall 2'of the cylinder base 2. A notch is formed in the vicinity of the pivot portion 4 of the body 3, and a wire diameter-reducing urging mechanism b is attached to the notch. The wire diameter-reducing urging mechanism b has two wires as shown in FIG. The outer case 8 in which the insertion pipes 7 and 7'and the two insertion pipes coexist integrally, the spring storage pipe 9 loosely fitted in each wire insertion pipe 7 and 7', and the tip of the spring storage pipe 9 respectively. The wire guide member 10 attached to the wire guide member 10, the wound spring 11 compressed and stored in the spring storage pipe 9, and the capture wire a at the end of the spring storage pipe 9 can be inserted in the direction of the wire loop portion a ”. In the opposite direction, it is composed of a stopper function member 12 that functions as a stopper and integrally fixes the capture wire a, and a free end wire a'in the capture wire a inserted into the winding spring 11.

The wire diameter reducing urging mechanism b functions as follows. That is, when the leg of the vermin stepped on the tread plate 6, the loop regulation of the loop portion a "of the capture wire a was released and pulled by the wire diameter-reducing urging mechanism b, and the loop portion a" was reduced in diameter. And capture the legs of the vermin. As shown in FIGS. 3 and 4, the operation is explained in chronological order. First, (i) the tread plate 6 comes off, (ii) the left and right wire holders 3 stand up by the urging of the coil spring 5, and (iii) capture. In the (iv) wire diameter-reducing urging mechanism b, the loop portion a "of the wire a is separated from the left and right wire holder 3 due to the displacement of the left and right wire holders 3 to the standing posture, and the regulation of the loop portion a "is removed. , The winding spring 11 stored in the wire insertion pipes 7 and 7'in the compressed state expands to move the wire guide member 10 to the loop portion a "side, and at the same time, the free end of the capture wire a via the stopper function member 12. The wire a'is pulled in the diameter-reducing direction of the loop portion a ", and (v) the loop portion a" that operates to reduce the diameter catches the leg of the pest by reducing the diameter while jumping up.

As shown in FIGS. 3 to 5, the stopper function member 12 is composed of an inner cylinder 11-1 and an outer cylinder 11-2 having a tapered inner peripheral surface. A ball insertion hole 11-3 is bored in the peripheral wall of the inner cylinder 11-1, and a spherical ball 11-4 is formed between the inner cylinder 11-1 and the outer cylinder 11-2. It moves through 3 and performs a wire insertion function in only one direction of the wire. Therefore, the free end wire a'of the capture wire a is pulled from the stopper function member 12 in the loop portion a "direction, and the loop portion a" is wound around the left and right wire holders 3 to complete the capture preparation.
Here, as shown in FIG. 4, when the winding spring 11 is housed in the wire insertion pipes 7, 7'of the wire diameter reducing urging mechanism b, it is compressed to the utmost limit to store the extension urging force. The compressed winding spring 11 is maintained in a compressed state under a fixed form with a loop portion a "of the capture wire a". That is, the capture wire a is one of the free ends at the position of the stopper functional member 12. The portion is fixed, and the other end is inserted and guided into the wire guide member 10 through the loop portion through the left and right wire holding bodies 3 in an immovable state. Therefore, the compressed winding spring 11 releases the extension urging. It cannot be used and is stored in a compressed state.
In this state, when the tread plate 6 is stepped on and the left and right wire holders 3 stand up and the restriction for maintaining the loop portion a "in the loop state is removed, the winding spring 11 compressed and stored in the wire insertion pipes 7 and 7'is released. The wire insertion pipes 7 and 7 ′ are separated from the wire guide member 10 by the elastic force of the extension in the direction of extension urging, and the diameter of the loop portion a ”is reduced. By that amount, the capture wire a changes from a tense state to a relaxed state.
At this time, as shown in FIG. 5, the capture wire a relaxed due to the reduced diameter appears from the tips of the insertion pipes 7 and 7'by the relaxed length. As a result, the stopper function member 12 at the rear end of the insertion pipes 7 and 7'is forcibly displaced backward by the winding spring 11, and the capture wire a is pulled to promote the diameter reduction of the loop portion. At the same time, the compressed winding spring 11 also protrudes from the front ends of the insertion pipes 7 and 7', and the extension urging operation of the winding spring 11 is linked to the diameter reduction operation of the loop portion of the capture wire a, and the binding function of the leg of the vermin Will be fulfilled.
As shown in FIG. 6, in the stopper function member 12, the balls 11-4 arranged in the ball insertion holes 11-3 come into contact with the tapered inner peripheral surface of the outer cylinder 11-1 to contact the inner cylinder 11-2. The free end wire a'is pressed by being displaced in the central direction of the free end wire a', and the free end wire a'and the stopper function member 12 are integrated.

In this way, the tread plate 6, the left and right wire holders 3, the loop-shaped catching wire a, and the wire diameter-reducing urging mechanism b activate the trap function of the vermin.
