Description

The present invention relates to a tying trap whose structure is devised so that it is lightweight, compact and easy to carry. More particularly, it relates to a tying trap with an improved rope holding frame so as to be lightweight, compact and easy to carry.

There are several types of traps for catching wild animals such as deer and wild boars, such as tying traps, box traps, and enclosure traps. Among them, the kukuri trap is a trap that is triggered by an animal stepping into the trap or touching the mechanism, and the trap is activated, and the wire rope is tied around the ankle to capture the animal. Compared to box traps and enclosure traps, traps are small and easy to carry, and are widely used as traps for catching animals.

As a trap that is often used, for example, a circular tread plate with a pair of semi-elliptical operating members is placed on a part called a cylindrical ring, and when an animal steps on the tread plate, the tread plate is attached to the ring. While descending inside, the tip of the elliptical arc of the operating member is caught in the frame of the frame, the operating member jumps up, and the tying ring of the wire rope wound by the operating member in the radially contracting direction is contracted. There is a tying trap that is bounced upwards while diametrically wound and ties the legs of the animal (Non-Patent Document 1, page 16, upper left photo. The mechanism for flipping up the operating member is slightly different, but Patent Document 1 can also be used as a reference. ).
In addition, as a special trap, for example, the footboard is divided into three parts in the center, left and right, and supporting legs are provided on the left and right footboards. The movement center (rotating axis) of the wire holding frame (corresponding to the operating member) becomes lower than the upper part of the support leg, the wire holding frame rotates upward, and the catching wire urged in the radially contracting direction A tying trap that is launched upward is known (see patent document 2, practical design 3168719 [0019], [Fig. 4]).

A plurality of tying traps are carried at the same time and set in various places, and it is preferable that they are lightweight, compact, and easy to carry. SUMMARY OF THE INVENTION An object of the present invention is to provide a lighter and more compact tying trap that is easy to carry by devising the structure of the tying trap.

As a result of various studies in order to achieve the above object, the present inventors have found that a part called a frame or a ring for upwardly rotating the rope holding frame used in the prior art is added to the rope holding frame as legs. The present invention, which is a lighter, more compact and easier-to-carry trap, has been achieved by integrating as a part. That is, the present invention is as follows.
1. A tread plate, a pair of semi-frame-shaped rope holding frames having legs at any position from end to end, and a rope wound around the pair of rope holding frames while being biased in a direction to reduce the diameter. A tying trap consisting of a rope loop,
With the trap set, the tread is clear of the ground and has a foothold;
The pair of rope holding frames are pivotally attached at their ends to the treads and are straight or slightly curved in side view so as to hold the biased rope loops with the trap installed. bent into a V shape,
The rope holding frame is a tying trap that rotates upward when the tread is pushed down, and the rope loop pops out while shrinking its diameter upward.
2. 1. The tying trap according to 1 above, wherein the half-frame-shaped rope holding frame has a substantially semi-elliptical arc shape, a substantially half-polygonal shape, or a shape that is a combination thereof.
3. A tying trap device consisting of a tread and a pair of half-frame-shaped rope holding frames having legs at any position from end to end,
With the trap set, the tread is clear of the ground and has a foothold;
The pair of rope retaining frames are pivotally attached at their ends to the treads and are linear to slightly curved in side view so as to retain a biased rope loop with the trap installed. bent into a V shape,

4. 3. The tying trap device according to 3 above, wherein the half-frame-shaped rope holding frame has a substantially half-elliptical arc shape, a substantially half-polygonal shape, or a shape combining these shapes.

According to the tying trap of the present invention, when the tread is pushed down, the rope holding frame is supported by the legs provided on the rope holding frame and pivots upward (FIGS. 2 to 4). By integrating parts called a frame and a ring for rotating the rope holding frame upward, which were conventionally required, into the rope holding frame as legs, the animal can be captured without lowering the effect of catching animals. The tying trap can be made lightweight, compact and easier to carry.

EXAMPLES The present invention will be described in detail below with reference to Examples, but the present invention is not limited to these Examples.

1. Structure of the tying trap of the present invention

(1) Overview The tying trap of the present invention comprises a tread 1, a rope holding frame 2 pivotally attached to the tread at its ends and having legs 4, and a rope loop 3 wrapped around the rope holding frame. (Fig. 1). When the animal pushes down on the tread, the rope holding frame rotates upward, and the rope loop urged in the direction of diameter contraction jumps out upward while contracting in diameter, and can tie the animal's leg (rope holding). The frame operates from Figure 2 to Figure 4 when the trap is activated).

(2) Footboard The shape of the footboard 1 is not particularly limited as long as it can be stepped on by an animal. For example, it may be elliptical, polygonal, or a combination thereof. The size of the treads is not particularly limited as long as it is easy for animals to step on. It is more preferable that the footboard has a non-slip so that the load of the animal is firmly applied to the footboard. The non-slip can be provided, for example, by arranging a plurality of hemispherical protrusions on the upper surface of the tread. More specifically, a plurality of screws may be screwed into the tread and the heads of the screws may be used as anti-slip (see, for example, tread 1 in FIG. 1).
The tread is away from the ground in the trap set state. It has a stepping margin so that it can be lowered when stepped on.

(3) Rope holding frame (i) About the rope holding frame The rope holding frame 2 exists in the shape of a frame, and half of the frame is paired and exists at the peripheral edge of the tread 1 so as to roughly surround the tread 1 ( Figure 2). A more specific shape is a substantially semi-elliptical shape, a substantially semi-polygonal shape, or a shape in which these are combined. Ellipses contain circles. Since it is substantially semi-elliptical, it does not have to be strictly semi-elliptical. The same applies to the substantially half-polygonal shape. For example, the substantially semi-elliptical arc may be a partial arc of an ellipse, or a part thereof may be linear. A parabola is also included in the approximate semi-ellipse if it does not deviate extremely from the shape of the ellipse.
A substantially half-polygonal shape also does not have to be exactly a polygon divided in half, and includes, for example, both left and right figures when divided by 1/3.
A shape in which a substantially half-ellipse and a substantially half-polygon are combined is, for example, one half of a square with greatly rounded corners, or a shape like a keyhole-shaped mound.

The rope holding frame 2 is rotatably attached to both sides of the tread 1 at both ends thereof. For example, when the tread is circular and the rope holding frame is semi-elliptical, both ends of the semi-elliptical rope holding frame are attached near both ends of the diameter of the circular tread. A second semi-elliptical rope-holding frame is attached at both ends in a similar position (Fig. 2). Then, the pair of semi-elliptical rope holding frames can be rotated up and down with the diameter of the circular footboard as the center of rotation (FIGS. 2 and 4).

The downward rotation range of the rope holding frame 2 is horizontal or slightly below the horizontal (Fig. 3). By winding the urged rope loop 3 while limiting the downward rotation range, the pair of rope holding frames are bent in a straight line or slightly in an inverted V shape when viewed from the side (Fig. 3 ), holding the rope loop. A downward rotation force is generated as the rope loop attempts to reduce its diameter, but this force is held back by the footboard 1. - 特許庁In other words, the treads act as stoppers to maintain the vertical shape. It should be noted that it is not necessarily the footboard that plays the role of the stopper. For example, if the rope holding frame is installed outside the tread (see, for example, Fig. 5), the tread does not act as a stopper, so some kind of stopper means should be provided to prevent the shaft from rotating downward too much. should be provided. This state in which the rope is held collapses when the footboard is pushed down, and the rope holding frame rotates upward.
Specifically, the downward rotation range is preferably 0 to 22.5 degrees from the horizontal direction, and more preferably 0 to 10 degrees.

A groove 7 may be provided around the outside of the rope holding frame 2 (FIG. 2), or a hook for hooking the rope loop may be provided to prevent the wound rope loop 3 from coming off.

(ii) Legs The rope holding frame 2 has legs 4 at any position from end to end (eg, FIG. 1). This is a major feature of the present invention.
When the trap is installed, since it is restrained by the rope loop 3 that is biased in the diameter-reducing direction, the rope holding frame does not rotate upward, and the tying trap of the present invention stands on its own due to the legs (Fig. If you compress the spring and set it in 1, it will be in this state). When a wild animal steps on the tread 1 of the tying trap of the present invention, the tread is pushed down, so that the rope holding frame starts rotating upward around the rotating shaft supported by the legs. Further, the force of the rope loop urged in the direction of diameter reduction causes the rope holding frame to be flipped upward (operating from FIG. 2 to FIG. 4). As a result, the rope loop, which has been biased and wound, is disengaged from the rope holding frame and pops out while shrinking in diameter, thereby tying the legs of the wild animal.

The leg part 4 has a shape that does not hinder the rotation of the rope holding frame 2 when the footboard separated from the ground becomes almost parallel to the ground when the trap is set and the footboard 1 is pushed down. For example, if the legs are columnar, even if the footboard is stepped on, the rope holding frame cannot rotate, so the shape prevents the footboard from being pushed down. If a triangular notch is made in the opposite position of the column with the rotation axis as the apex to form a pair of legs (Fig. It is a shape that does not exist. As long as the legs fit in this shape and the treads can be almost parallel to the ground when setting the trap, the number, shape, and installation position of the legs can be freely selected.
For example, there may be two legs at opposite positions of the major axis of the ellipse (Figs. 2 and 3), or one half-ellipse with one leg and the other half-ellipse with two legs. may be attached. A pair of legs is formed by making a triangular notch with the rotation axis as the apex at the opposite position of the column. may be present (Fig. 5).
Naturally, when the trap is installed, the legs of the rope holding frame are located outside the outer circumference of the treads so that the legs can touch the ground without being obstructed by the treads.

To further reduce the weight of the tying trap of the invention, the legs 4 of the rope holding frame 2 may be perforated 6 (Fig. 1). Holes can be drilled to reduce weight while balancing the loss of strength.

Moreover, it is also possible to attach legs to a rope holding frame without legs to form a tying trap of the present invention.

(iii) Effect of adding legs In the present invention, parts called frames and rings, which were conventionally required, are integrated into the rope holding frame as legs to make the tying trap lighter and more compact. . In other words, the provision of the legs eliminates the need to use components called frames and rings. In this way, integration (removal of need) and reduction in weight and size make it easier to carry. Furthermore, in the case of the prior art (Non-Patent Document 1) in which the step board is divided into three parts, depending on the position where the animal steps on, it is conceivable that the tying trap may be difficult to operate. The trapping effect can be maintained in the same manner as the conventional product (for example, non-patent document 1, page 16, upper left photo). In addition, since parts such as a frame and a ring are not required, the number of parts can be reduced and the manufacturing cost can be reduced.

(4) Rope loop When setting up a tying trap, the rope loop 1 wound around the rope holding frame 2 is biased in a diameter-reducing direction. For example, a rope loop can be made by looping one end of the rope through the other end and using a spring to urge the rope loop in a radially contracting direction.
The method of using a spring to apply force in the diameter-reducing direction includes, for example, a method of pushing the ring with a compression spring or a torsion spring (Fig. 1, it is possible to apply force by compressing and setting the compression spring 5), and a pull spring to tighten the rope. There is a way to pull the other end.
The rope to be used may be a fiber rope or a wire rope, but it is more preferable to use a wire rope so that it is less likely to break even if the prey rampages.
In addition, various parts attached to the rope for the tying trap, such as the spring guard 8 that accommodates the compressed spring, the twist, the wringer, the tightening prevention, and the like, may be appropriately attached to the rope loop. The spring guard can be damaged if the prey caught in the trap acts violently, but if you cut it into multiple pieces and create joints, it will be less likely to be damaged. In this case, when compressing the compression spring, it is difficult to bend the joint, so it is preferable to provide a pipe having a larger diameter and capable of moving on the spring guard so as to cover the joint. When compressing the compression spring, by moving the pipe so as to cover the joint, the compression spring can be compressed and housed in the spring guard without bending the joint.

INDUSTRIAL APPLICABILITY The tying trap of the present invention is lightweight, compact, and easy to carry, so it promotes the spread of tying traps and is useful in the industrial field of trap production.
