Description

[Detailed description of the invention] (Target of the invention, field of industrial application) The present invention relates to an animal trap that can quickly set the trap and reliably capture prey.

(Prior art and its problems) The inventor of the present invention has already proposed the method shown in Fig. 5 in Japanese Patent Application No. 59-61325 (Japanese Patent Publication No. 63-44334) to solve the problems of conventional animal traps. An animal trap 50 as shown is proposed.

This animal trap 50 has the advantage that large animals can be captured and the trap itself and the wire rope are unlikely to be damaged. However, when installing the animal trap 50, the front and rear parts are fixed by the fixed rod 590 and the fixed stake T3, so when the jumping arm 52 jumps up, it jumps up around the pin 591, and the trapping part 521a is pulled toward the pin 591 side. This caused the prey to lose its footing, resulting in failure to capture it. Therefore, in order to increase the trapping efficiency, when installing the animal trap 50, the through fitting 5
A tightening wire rope 522 (also shown as an imaginary line in FIG. 1), which is tied to a standing tree, etc., was attached to the tip of the 20, and tied to the standing tree T2. As a result, the catching part 521a of the wire rope 521 does not get caught by the legs of the prey, and since the catching part 521a is well tightened, it does not come off easily even if the prey becomes violent. Need, standing tree T
It has to be tied to 2, and that's how much trap 5
It takes a long time to install 0.

Therefore, the inventor of the present invention made further improvements and completed an animal trap that can be caught more reliably and that can be set up quickly.

(Purpose of the present invention) The purpose of the present invention is to
In addition to the features of the animal trap proposed in No. 61325, this animal trap has features such as being able to set the trap more quickly and having a high capture rate regardless of the position of the prey's feet in the trap when the trap is activated. The goal is to provide the following.

(Structure of the invention) The technical means taken to achieve the above purpose are as follows. That is, the present invention has the following features: (a) a base arm, a flip-up arm that is provided on the base arm so that it can be raised freely; It is equipped with a tread holder for latching and a rope for capturing the prey; (b) the tread holder is attached so that when it moves downward, it releases the latching of the flip-up arm and separates from the base arm; (c) The rope has a trap formed at its end that tightens when the jumping arm is raised, and the rope is tightened by the movement of the captured prey or by the movement of the captured prey. This animal trap is designed to be detachable from the trap, and is characterized in that a fixed rod holder is rotatably attached to the base arm.

(Example) The present invention will be explained in more detail based on an example shown in the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is an enlarged view of the main part of the fixed rod holder.

The trap T includes a base arm 1 and a jumping arm 2 that jumps up and pulls up a wire 21. A fixed rod holder 8 for installing the base arm 1 on the ground is rotatably supported on the base arm 1.

The fixed rod holder 8 is used to attach a fixed rod that is driven into the ground, and is generally cylindrical in shape.

A mounting portion 81 having a square cross-sectional shape is formed in the upper part of the fixed rod holder 8, and the tip of the base arm 1 is fitted into the mounting portion 81, and is rotatably mounted by a pin 82.

This allows the rear part of the base arm 1 to jump upwards about the attachment part 81 at the same time as the trap T operates. Also, the pin 82 of the mounting part 81
A locking hole 83 is formed slightly behind the base arm 1, and a through hole (not shown) is formed in the base arm 1 at a position that matches the locking hole 83. The fixing rod holder 8 can be fixed to the base arm 1 by inserting a retaining pin 85 into the retaining hole 83 and the through hole of the base arm 1.

At the lower front side of the base arm 1 and slightly behind the mounting part 81, a mounting part 4 is formed to which one of the coil springs S, which will be described later, is mounted.

A flip-up arm 2 is attached to the rear end of the base arm 1. The flip-up arm 2 has a rear portion bent downward to form an attachment portion 3 to which the other side of the coil spring S is attached. The flip-up arm 2 is rotatably attached by being pivotally supported by a pin 91 at a slightly rear side of the bent portion.

Note that when the coil spring S that is attached across the attachment parts 3 and 4 is covered with a cover C and buried in the soil, the tension force will be weakened due to soil etc. I try not to have any.

A notch 9 is formed in the center of the tip of the base arm 1 toward the rear end in the axial direction, and a latching pin 61 is provided passing through the notch 9 at right angles to the axial direction. A footboard holder 11, which will be described later, can be hung thereon.

A pulley bearing 6 is formed on a side portion of the base arm 1 slightly on the front end side of the center portion, and a pulley 7 is pivotally supported. The pulley 7 is attached with a pin 71 that is easy to attach and detach. The pin 71 is formed long so that one or both ends protrude from the pulley 7 when the pulley 7 is attached, and is secured with a rubber ring 72, but the pin 71 is designed to be relatively easily removed from the pulley 7. .

A safety device 5 is erected at a required position on the base arm 1, and by inserting a pin after pushing down the flip-up arm 2, it is possible to prevent the flip-up arm 2 from accidentally jumping up. .

A pulley bearing 6a is attached to the side of the tip of the flip-up arm 2.
A pulley 7a is pivotally supported on the pulley bearing 6a.

The pulley 7a is attached with a removable pin 71a. The pin 71a is formed long so that one or both ends protrude from the pulley 7a when the pulley 7a is attached, and is fixed with a rubber ring 72a, but the pin 71a is designed to be relatively easily removed from the pulley 7a. .

The treadle support 11 has a generally T-shaped overall shape when viewed from above, and has a receiving portion 111 for the treadle A at its tip. Also, on the back side, there is a base arm 1 approximately in the center.
A hooking piece 112 is formed. Step board support 11
A latching convex portion 10 for latching the tip of the flip-up arm 2 is provided at the base of the holder. Further, the locking piece 112 is formed with a pin locking recess 101 (shown in FIG. 3) that locks the locking pin 61 provided on the base arm 1.

In other words, the treadle support 11 rotates downward about the latching pin 61 and then separates from the base arm 1 when the end of the flip-up arm 2 is unlatched.

21 is a wire rope, one end is a pulley 7, 7a
Capture part 21 with the tread A side shaped like a ring by hanging between
It forms a. Further, a wire rope 24 is attached to the other end to be attached to a standing tree T1 or the like via a monkey ring 25. The wire rope 24 has one end slackened, and a coil spring 26 is installed before and after the slackened end.
is attached to provide a buffer function.

A part of the wire rope 21 is attached to the rear of the flip-up arm 2 by inserting it loosely with a wire 30, so that the wire rope 21 draws a W-shape when the flip-up arm 2 is raised.
The amount of pull is increased.

According to this, if the opening angle and length of the base arm 1 and the flip-up arm 2 are the same, the ring-shaped portion formed at the tip of the wire rope 21 can be made larger, and the capturing efficiency is improved.

Reference numeral 23 denotes a stopper which is hooked on the wire 30 when the hoisting arm 2 is lifted up, thereby tightening the wire rope 21 formed in a ring shape on the side of the footboard A.

A threading fitting 20 is attached to the tip of the wire rope 21, and the wire rope 21 is passed through it.

The through fitting 20 is formed in a substantially U-shape, and has through holes 200 and 201 (not visible in the figure) formed in both side walls, respectively, and an oblong through hole 202 formed in the back wall. And the tip of the wire rope 21 is
From the through hole 200 on one side wall to the through hole 20 on the back wall
2 and the other through hole 201, and a stopper 203 is fixed to the tip to prevent it from coming out of the through fitting 20.

The material of the trap T is aluminum or synthetic resin, and the material of the wire rope 21 is also aramid fiber (trade name: Kevlar, DuPont).
It is preferable to use iron, as it is lighter and does not smell like iron, and also has the advantage of being less likely to harm the prey.

Moreover, there is no problem in forming a hanging protrusion on which the wire rope 21 can easily slide instead of the above-mentioned pulley.

FIG. 3 is an explanatory diagram showing the installed state of the trap T, and FIG. 4 is an explanatory diagram showing the trap T in an activated state. The operation of this embodiment will be explained with reference to FIGS. 3 and 4.

A fixing rod 90 is inserted and fixed into a fixing rod holder 8 for installing the trap T on the ground, and a pit hole 300 and a setting hole 301 are dug in the animal trail and the trap T is installed as shown in FIG. When installing the trap T, if the locking pin 85 is inserted into the locking hole 83 of the mounting portion 81, the fixed rod holder 8 will be firmly fixed to the base arm 1, making installation easier. Of course, after setting the trap T, remove the latching pin 85. A tread A is placed above the pit 300, and the entire trap T is covered with soil.

When the prey places its foot on the tread A, the tread holder 11 rotates downward around the latching pin 61 due to its weight, so the tip of the jumping arm 2 is attached to the latching protrusion 10.
When it comes off, the latching condition is released and the flip-up arm 2
jumps up. At this time, at the same time that the flip-up arm 2 jumps up, the tension of the wire rope 21 also causes the rear of the base arm 1 to jump upward around the attachment part 81. Further, since the rear portion of the trap T itself is not fixed, it can rotate around the fixed rod 90 and follow the movement of the prey. As a result, the tip of the jumping arm 2 jumps up in a substantially vertical direction, and the catching portion 21a of the wire rope 21 also follows and rises. Therefore, the capturing part 21a does not sweep the legs of the prey, but rises along the legs, and the prey has no room to pull out its legs, and the base of the legs are surely tied and captured.

In addition, the conventional animal trap 50 required a tightening wire rope 522 in order to increase the trapping efficiency, but according to the present invention, the tightening wire rope 522 and its installation work are unnecessary, and the trap T can be reduced by that amount.
can be installed quickly.

Further, the footboard support 11 is detached from the base arm 1 after rotating downward about the latching pin 61.

Prey becomes violent after being captured, so rubber rings 7
The pins 71, 71a held by the pins 2, 72a come off from the pulleys 7, 7a, and the pulleys 7, 7a come off the trap T. Further, since the wire 30 also comes off from the trap T, only the wire ropes 21 and 24 remain after the prey is captured, and the trap T will not be damaged even if the prey goes wild.

(Effects of the invention) According to the invention, in addition to the features of the animal trap previously proposed by the inventor in Japanese Patent Application No. 63-44334, (a) During capture, the trap itself follows the prey, and the capture part also rises almost vertically along the prey's legs, making it difficult for the prey to escape and ensuring that the base of the legs is tied, so that when the trap is activated, the prey remains in the capture part. Capture rate improves regardless of foot position.

(b) There is no need to fix the rear of the base arm to the ground with stakes, etc., it is only necessary to fix it with the front stake. In addition, there is no need for a wire rope and its installation work, and the pit hole below the tread only needs to be deep enough to not interfere with the operation of the trap, so there is no need to dig as deep as in the past. This allows traps to be set up more quickly.

We can provide animal traps with the following features.
