Description

DETAILED DESCRIPTION OF THE INVENTION (Subject of the invention, field of industrial application) The invention is used in the field of animal traps. The present invention relates to an animal trap that prevents breakage of the trap and allows confirmation of whether or not the animal has been caught.

(Prior art and its problems) A conventional animal trap has the structure shown in FIG. 7, but this animal trap has the following problems.

(a) Since the U-shaped leaf spring 50 is used, the flip-up arm 2a can only be raised to the position 9a, and the opening angle with respect to the fixed arm 1a is small. For this reason, the capture portion 21a formed in a ring shape on the footboard B
It is not possible to increase the diameter of the rod, so the probability of catching prey is small and it is impossible to capture large animals.

(b) Since the wire 21a is passed through the through hole 29 provided at the tip of the flip-up arm 2a, when the flip-up arm 2a goes up, the wire 21
There is an angle between the wire 21a and the flip-up arm 2a, which makes the wire 21a easy to break.

In addition, since the flip-up arm 2a does not rise smoothly and also rises slowly due to friction, the prey may escape.

(c) Since the treadle board B is rotatably attached to the fixed arm 1a without being removed, if the prey becomes violent, the connecting portion between the fixed arm 1a and the treadle B will be damaged and cannot be used again.

In addition, large animals such as wild boars and bears run wild when caught in a trap, so in the case of the integrated trap shown in FIG. 7, the wire 21a may wrap around the trap and break.

(d) In order to confirm whether traps have been captured or not, it is necessary to inspect the locations where traps are set up, but it takes a lot of time to inspect large areas. Also, protected animals (hounds, maybe Japanese,
When a female deer (such as a female deer) is caught in a trap, it must be quickly released to prevent injury, and it is necessary to confirm as soon as possible whether the animal caught in the trap is a protected animal or not.

However, there are no traps that can tell the trap setter whether prey has been caught or not, and what the size of the prey is.

OBJECTS OF THE INVENTION A first object of the invention is to prevent breakage of the trap by allowing the rope to be removed from the trap when prey, especially large game, is captured.

The second object of the present invention is to quickly confirm whether prey is caught in a trap or whether it has ever been caught in a trap, and to quickly confirm whether prey caught in a trap is a protected animal or a game animal. We provide an animal trap that makes it possible to

(Structure of the Invention) The technical means taken to achieve the above first objective are as follows.

(a) The trap consists of a fixed arm, a jump arm that is attached to the fixed arm so that it can be raised freely, and a treadle holder that is installed at the tip of the fixed arm and that hooks the jump arm in a state that resists elasticity. (b) The treadle holder is mounted so that when it moves downward, it releases the latching of the flip-up arm and separates from the fixed arm; (c) ) The rope is designed so that the trapping part formed at the tip tightens when the jumping arm jumps up, and furthermore, the rope can be tightened by the movement of the captured prey or by the movement of the captured prey. It is arranged so that it can be removed from the

The technical measures taken to achieve the above second objective are as follows.

(a) The trap consists of a fixed arm, a jump arm that is attached to the fixed arm so that it can be raised freely, and a treadle holder that is installed at the tip of the fixed arm and that hooks the jump arm in a state that resists elasticity. (b) The treadle holder is mounted so that when it moves downward, it releases the latching of the flip-up arm and separates from the fixed arm; (c) ) The rope is designed so that when the jumping arm jumps up, the trap formed at the end of the rope tightens, and the rope can be tightened by the movement of the captured prey or by the movement of the captured prey. (d) be equipped with a transmitter that operates in conjunction with the movement of the flip-up arm, or in conjunction with the movement of the flip-up arm and the movement of the prey;

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

FIG. 1 is a perspective view showing a first embodiment of the present invention.

The trap T includes a fixed arm 1 fixed to the ground and a jumping arm 2 that jumps up and pulls up a wire 21.

The rear part of the flip arm 2 is bent downward,
One attachment portion 3 of a coil spring S1, which will be described later, is formed.

The rear end of the fixed arm 1 is attached with a pin 91 slightly to the rear of the bent portion of the attachment portion 3.

The other attachment part 4 of the coil spring S1 is formed on the lower front side of the fixed arm 1, and the coil spring S1 is attached between it and the attachment part 3.

Note that the coil spring S1 is covered with a cover C to prevent the soil from getting caught when buried in the soil, so that the tensile force is not weakened.

Further, a fixing rod holder 8 for fixing the trap T is formed on the lower front side of the fixing arm 1 on the front end side of the attachment part 4.

A notch 9 is formed in the center of the tip of the fixed arm 1 toward the rear end in the axial direction, and a latching pin 61 is provided to pass through the notch 9 at right angles to the axial direction. The treadle support 11 can be hung thereon.

A pulley bearing 6 is formed on a side portion of the fixed arm slightly toward 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 fixed with a rubber ring 72, but the pin 71 is designed so that it can be easily removed from the pulley 7. be.

A safety device 5 is erected at a required position on the fixed arm 1, and a pin is inserted after the flip-up arm 2 is pushed down 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 by 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 able to come out from the pulley 7a.

The tread support 11 is formed into a substantially T-shape in plan view,
As shown in FIG. 3, a receiving portion 111 for the footboard A having an L-shaped cross section is provided.

A hooking piece 112 for attaching to the fixed arm 1 is formed approximately in the center of the footboard holder 11.

The latching piece 112 is formed with a latching protrusion 10 for latching the tip of the flip-up arm 2 and a pin latching recess 101 for latching the latching pin 61.

Then, the footboard holder 11 rotates downward about the latching pin 61 and then separates from the fixed arm 1.

21 is a wire rope, one end is a pulley 7, 7a
It is formed in a ring shape on the tread A side by spanning between the
A wire rope 24 is provided at the other end to be attached to a standing tree T1 or the like via a ring 25.

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.

This means that if the opening angle and length of the fixed arm 1 and the jumping arm 2 are the same, the wire rope 2
The annular portion formed at the tip of 1 can be made larger, resulting in improved capture efficiency.

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, with through holes formed in both side walls and an oblong through hole formed in the back wall. The tip of the wire rope 21 passes from a through hole in one side wall to a through hole in the back wall, passes through the other through hole, and has a stopper fixed to the tip to prevent it from slipping out of the fitting 20.

Note that it is preferable to use aluminum or synthetic resin as the material for the trap T because it is lightweight and does not smell like iron.

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.

This embodiment works as follows.

A fixed rod 9 is attached to a fixed rod holder 8 that fixes the trap T.
0, and as shown in Figure 3, dig a trap hole and a hole in the animal trail and set the trap T.

Place tread A on top of the trap and cover the entire trap T 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.

Then, the ring-shaped part of the wire rope 21 tightens and ties the legs of the animal, and the prey is captured.

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

When setting up the trap T, if a string 22 is attached to the tip of the threading fitting 20 and tied to the tree T2, the wire rope 21 will be tightly tightened and will not come off even if the prey goes wild.

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. Moreover, since the wire 30 also comes off from the trap T, after the prey is captured, only the wire ropes 21 and 24 remain as shown in FIG. 6, and the trap T will not be damaged even if the prey goes wild.

FIG. 2 shows another embodiment of the spring, in which a helical spring S2 is used as the spring.

FIG. 4 shows another embodiment of the latching pin.

A latching bolt 80 is used as the latching pin 61, and the tread plate holder 11 is tightened with the wing nut 81.

82 is a spring that prevents the wing nut 81 from loosening.

In this embodiment, the falling weight of the footboard holder 11 can be adjusted by tightening the wing nut 81, so if the wing nut 81 is adjusted according to the target prey, the footboard holder 11 can be adjusted in the case of small prey. does not fall, making it possible to sort prey.

Further, due to the tightening, the treadle support 11 does not fall even if the jump arm 2 is stepped on, so the trap T is not operated idly, and the prey does not become alarmed. Note that parts corresponding to those in FIG. 1 are designated by the same reference numerals.

FIG. 5 shows a further development of the present invention.

In the present invention, the transmitter 100 is attached to the trap T or placed at an appropriate position near the trap T. The transmitter 100 used has a structure that turns on when the pin is pulled out.

The transmitter 100 has three pins 100a, 100
b, 100c are inserted, and one end of a thin wire rope 101, 102, 103 is attached to each pin.

This embodiment works as follows.

The other end of the wire rope 101 is attached to a stake or standing tree T3 near the tread A.

The wire rope 102 is attached to the hoisting arm 2, and the wire rope 103 is attached to a standing tree T4 located at a distance from the trap T within the range of a circle drawn around the standing tree T1 to which the wire rope 24 is tied.

If the prey is not caught and only the jumping arm 2 jumps up, the wire rope 102 is pulled, the pin 100b comes out, and only the jumping arm 2 jumps up, and an idle operation signal (for example, a 3-second transmission) is performed. .

Next, when a medium-sized animal (fox, raccoon, marten, dog, etc.) gets caught in the trap T, it goes berserk, but since the medium-sized beast does not have the strength to pull the trap T out of the ground, it goes wild in the position where it gets caught. Therefore, the two pins 100a, 1
00b is missing, medium-sized beasts (fox, raccoon, marten,
A call (for example, a 4-second call) is made that a dog (such as a dog) is caught in the trap T.

Further, when a large animal (a boar, a bear, etc.) gets caught in the trap T, it becomes violent, and in order to pull the trap T out of the ground, it goes wild centering on the standing tree T1 to which the wire rope 24 is attached.
Therefore, the three pins 100a, 100b, 10
All 0c's are removed, and the transmission made by the large beast (for example, a 7 second transmission) is made.

According to this invention, if a receiver is provided, it is possible to tell the difference between idle-acting animals, medium-sized animals, and large-sized animals, thereby saving the trouble of looking around.

(Effects of the Invention) As described above, according to the present invention, the rope for capturing the prey can be removed from the trap depending on the movement of the captured prey or without depending on the movement of the captured prey, so that the trap is not damaged. You can use it as many times as you want without having to worry about it.

Furthermore, if the rope is strung between the fixed arm and the flip-up arm, the length of the rope that can be pulled will be increased, and the size of the trapping section can be increased, which can be expected to improve the trapping efficiency.

Furthermore, when prey is captured, the transmitter activates and sends out a signal, so you can confirm whether prey has been captured without having to go check the trap.
