  The present invention relates to an animal trapping hook that binds and captures leg portions of animals such as a spider and a deer with a wire, and more particularly to a trigger device used for the hook.

  2. Description of the Related Art Conventionally, as a device that captures beasts such as spiders and deer, a scissor that captures the legs of a beast with a wire or the like is generally used. As a general binding rod, for example, a binding rod as shown in Patent Document 1 has been proposed. The binding rod is formed of a cylindrical main body embedded in or near the passageway of the capture target and a flexible long material, and is inserted through the main body and pulled out from the main body to be the capture target. A catching squeezing member provided with a ring-like squeezable portion that can be tightened at one end extended on the passageway, a tightening body fitted in a state in which the squeezing squeezing member passes through the top of the main body, and this fastening A member that is guided by the squeezing squeezing member and urges the body in a direction toward the annular squeezing part, and a region on a passageway surrounded by the annular squeezing part of the capturing squeezing member, and is displaced according to the weight of the subject to be captured A weight receiver and a lower region of the weight receiver are rotatably supported by the main body, one piece is connected to the lower surface of the weight receiver, and the other piece is provided on the fastening body. A displacement transmitting member engaged with the engaging groove, The fastening body is restrained to the main body against the urging force of the urging member by the other piece of the displacement transmitting member, and when the weight to be captured acts on the weight receiver, the piece is interlocked with the other piece. Is rotated and displaced to release the constraint on the main body, and the tightening body is pressed against the ring-shaped throttle portion of the capture diaphragm by the biasing force of the biasing member to tighten the ring-shaped throttle portion, and the body to be captured is tightened. It is characterized in that any part is praised and captured.

  However, since the buried type hooks described in Patent Document 1 need to be buried in the ground, the number of man-hours for the installation work is large, and the vicinity of the installation site is muddy due to the soil discharged from the buried hole. There was a problem that it was easily felt by dirt and beasts. Therefore, as shown in Patent Document 2, a hook that can be installed without being buried in the ground has been proposed. The binding rod described in Patent Document 2 includes a pair of plate-like members around which a wire of the binding rod is turned, a base portion that rotatably holds the plate-like member, and a pair of plate-like members provided in the base portion. There has been proposed a safety device for a hook that is composed of a footboard that rotates the members relative to each other, and is configured such that when a foot pressure is applied to the footboard, the pair of plate-like members are rotated to release the tightening of the wire.

  However, the binding rod described in Patent Document 2 has a structure in which the wire is turned around in a state where the pair of plate-shaped members are in contact with the installation surface, and the base portion needs a predetermined height. There was a problem that the size of itself was bulky and the hooks installed on the surface of the earth were conspicuous. In addition, the plate-shaped member has a downward angle from the horizontal in the set state, and the rotation angle from the state where the wire is turned to the state where it is released is large. There was a problem that a series of operations until the wire was bundled took time, and the capture rate was lowered.

  The present invention has been made in view of the above-mentioned problems, and can easily install a hook without excavating the ground, and can operate instantaneously when a beast steps on to improve the capture rate. An object of the present invention is to provide a trigger device for a bundle hook.

  For this reason, the trigger device for a leash according to the present invention is a trigger device to which a wire that is installed on the ground surface and ties a leg of a beast is attached, and is composed of first and second semi-annular strips that are connected to each other A wire mounting body rotatable at the connecting portion of the semi-annular belt body, a support bar fitted to the inner periphery of the first and second semi-annular belt bodies, and a tread plate placed on the support bar. The first feature is that the first and second semi-annular strips have a notch recess in the center in the longitudinal direction, and a support bar is provided on the upper portion of the notch recess.

  In addition, the first and second semi-annular strips are connected by bolts provided on the installation surface side from the center line in the short direction, and the first or second half A third feature is that the annular band has a screw hole into which the support bar can be screwed at a position where the support bar abuts.

(1) Since the support rod is set in the vicinity of the upper portion of the notch recess, when the animal steps on the tread board, the support rod can instantly slide into the notch recess to operate the hook. That is, the time from when the beast steps on the footboard until the wire ties the leg of the beast is short, and the capture rate can be improved.
(2) Since the first and second semi-annular strips are connected by bolts provided on the installation surface side from the center line in the lateral direction, the wire tightens when the support bar slides. The first and second semi-annular belts can be converted to rotational force, and the wire attached to the wire attachment body can be instantaneously detached, and the leg of the animal located on the tread can be tied with the wire. it can.
(3) Since the first or second semi-annular strip is provided with a screw hole in which the support rod can be screwed at a position where the support rod abuts, the first and second semi-annular strips are rotated. It can be surely prevented from moving. Therefore, for example, when installing a binding rod, it is possible to prevent the rod from operating accidentally and improve safety.
(4) By adopting a simple configuration, the device itself can be manufactured without being bulky in size, particularly in height. Therefore, it can be installed without conspicuous on the ground surface, and the capture rate can be improved.

It is a perspective view which shows the trigger device for a hook according to the present invention. It is sectional drawing explaining the state which sets the hook in the trigger apparatus for hooks which concerns on this invention. It is sectional drawing explaining the state which the trigger device for a hook according to this invention act | operated. It is sectional drawing explaining the state in which the leg 99 of the beast was tied by the trigger apparatus for the hook according to the present invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the safety device 1 according to the present invention includes at least a wire mounting body 2, a support bar 3, and a tread plate 4, and a loop-shaped wire 9 is fastened to the outer periphery of the wire mounting body 2. Installed on the surface. In general, when the tread plate 4 and the support rod 3 are detached from the wire mounting body 2 by the treading pressure of the leg of the animal, the wire 9 is released from the state in which the wire 9 is set on the standing tree or the like, and the reduced diameter wire 9 becomes the animal. It is intended to capture the beasts by tying the leg of the frog. In addition, since the structure of the hook is well known, illustration and description are omitted except for the wire 9 of the hook.

  As shown in FIGS. 1 and 2, the wire mounting body 2 includes a pair of metal strips formed in a semi-annular form, that is, a first strip plate 21 and a second strip plate 22. The first band plate 21 and the second band plate 22 are connected to each other at their opposite end portions by bolts 51 and 52, and the wire mounting body 2 is formed in an annular shape as a whole. Yes. Moreover, the 1st strip 21 and the 2nd strip 22 are each provided with the notch parts 211 and 221 in the center part of the longitudinal direction. Therefore, as shown in FIG. 2, the support bar 3 set above the notches 211 and 221 slides to the positions of the notches 211 and 221 as shown in FIG. .

  When the first band plate 21 and the second band plate 22 rotate, the first band body 21 side is provided for the purpose of preventing the rotation speed from decreasing due to the contact of both ends. An inclined portion 212 is provided at the end. Any shape may be used as long as it can reduce the contact area of the both end portions of the first band plate 21 and the second band plate 22 and is not limited to the illustrated inclined shape.

  The second band 22 has a screw hole 222 through which the thumbscrew 6 is inserted above the notch 221, and the support rod 3 is connected to the inner periphery of the first band plate 21 and the second band plate 22. Used when setting to. The support rod 3 is a metal rod-like body, and a bolt 31 is once fixed to the side. As shown in FIG. 2, the bolt 31 on one end side is brought into contact with the inner circumference of the second belt body 22, and the other end side is brought into contact with the inner circumference of the first belt body 21. Screw. After the wire mounting body 2 is in a state in which the rotation is restricted, the wire 9 is mounted on the outer periphery of the wire mounting body 2 and the thumbscrew 6 is removed. Therefore, the support bar 3 serves to regulate the rotation of the wire mounting body 2 and to release the rotation regulation of the wire mounting body 2 when the support bar 3 slides.

  A tread board 4 made of a metal net is supported by a support bar 3, and is configured to slide when the tread board 4 is stepped on. The tread plate 4 is fixed to the bolts 51 and 52 by inserting wire members 71 and 72 such as wires to the edge thereof, and the tread plate 4 is placed on the support bar 3 in a stable state. As shown in FIG. 1, the tread 4 is preferably a net having a predetermined mesh width. This is to prevent the support bar 3 from detaching due to the weight of pebbles or soil placed on the tread board 4, and it has moderate lightness such as punch metal, and can be loaded on the tread board 4. Anything that can be prevented can be used.

  As described above, the safety device 1 according to the present invention includes the wire mounting body 2 including the first belt body 21 and the second belt body 22, and the tread plate 4, the bolts 51 and 52, and the wire member 71, 72, and can be used simply by providing the support rod 3 on the inner periphery of the wire mounting body 2 and on the lower part of the tread plate 4, and a hook can be easily installed. In addition, compared to conventional hooks, there is no need for a digging section for burial, and it is only necessary to carry the hooks and the safety device 1, so that the burden on the installation worker is sufficiently reduced in this respect as well. Is done.

  The safety device 1 is used by being transported to a place of installation together with a hook. When arriving at the installation location of the hook, first, as shown in FIG. 2, dead trees and stones are removed from the installation location to create a relatively flat installation surface GL. Next, the first belt body 21 and the second belt body 22 of the safety device 1 are rotated so as to be horizontal to each other, and a support bar 3 is provided to support the tread 4 on the inner periphery thereof. The second belt 22 is screwed and fixed with the thumbscrew 6 so that the rotation of the first belt 21 and the second belt 22 is restricted. This operation may be performed before arrival at the installation location, and the safety device 1 in a state where the rotation is restricted may be carried and installed on the installation surface GL as it is.

  Next, a hook is connected to a standing tree or the like, and the wire 9 of the hook is turned around the outer circumference of the first belt body 21 and the second belt body 22, that is, the outer circumference of the wire mounting body 2, and the wire 9 is tightened. At this time, the wire 9 is attached to the upper edge portion of the wire attachment body 2 as shown in FIG. Therefore, as shown in FIG. 2, the wire mounting body 2 is urged by the pressing force P1 in the inner circumferential direction. Thereafter, the thumbscrew 6 is removed to complete the installation work. If necessary, the hook and safety device 1 may be covered with fallen leaves or soil.

  Next, the operation of the safety device 1 and the binding rod will be described. When a beast such as a spider or a deer passes through the installed safety device 1, the leg 99 of the beast steps on the tread plate 4, and the tread plate 4 and the support bar 3 slide downward as shown in FIG. Then, the first belt body 21 and the second belt body 22 rotate with respect to each other in the direction (the direction of the arrow shown in FIG. 3) that stands with the bolts 51 and 52 as axes. That is, when the tread board 4 and the support bar 3 slide downward, the force that opposes the pressing force P1 is lost, and the restriction of the rotation is released, and the first belt body 21 and the second belt body 22 are released. Rotates and the wire 9 wound around the outer periphery is detached upward. Since the wire 9 is urged in the direction of reducing the diameter by the urging means of the hook and the like, the wire 9 is pulled down upward while instantaneously reducing the diameter by this urging force, and approaches the leg 99 of the beast. . Therefore, as shown in FIG. 4, the wire 9 can be securely tied to the leg 99 of the animal that escapes upward from the tread 4 simultaneously with the operation of the hook, so that the animal can be captured.

  In order to reliably capture the beast, the speed from when the leg 99 of the beast steps on the tread board 4 until the wire 9 is fastened is important. In the present invention, this is the most troublesome point. The beast that feels anomaly tries to detach the leg 99 from the tread 4 very quickly. Therefore, in the present invention, as shown in FIG. 2, the bolts 51 and 52 are provided on the installation surface GL side from the center line S in the short direction of the first band plate 21 and the second band plate 22, and By disposing the wire 9 above the center line S, when the restriction is released, the direction of the pressing force P1 of the wire 9 is changed to a rotational force P2 as shown in FIG. 99. Moreover, by providing the support bar 3 above the notches 211 and 221, the sliding amount of the support bar 3 when the treadle 4 is stepped on can be minimized, and the restriction of rotation can be quickly released, and the capture of the animals The rate can be improved.

  Further, in the present invention, as shown in FIG. 1, a gap space 8 is provided between the periphery of the tread board 4 and the inner periphery of the wire mounting body 2 (the first belt body 21 and the second belt body 22). Yes. As shown in FIG. 4, it is desirable that the gap space 8 has a gap distance t that is approximately the same as the leg bottom radius W of the leg portion 99. For example, when the gap distance t is insufficient, when the animal steps on the upper part of the wire mounting body 2 at the center of the leg 99, the toe or the like steps on the tread plate 4, and the trigger device 1 operates, so-called empty repelling Invite. Once the empty frogs are trapped, they will not be able to capture the beasts after that, but will not be able to pass through the beast roads where the monsters have guarded and set the lances. Therefore, in the present invention, by providing the gap space 8, even when the wire attachment body 2 is stepped on, the stepping plate 4 is not stepped on and the trigger device 1 is prevented from operating, and when the stepping plate 4 is securely stepped on. It is possible to improve the capture rate of beasts by configuring so as to operate only in

  The configuration of the trigger device according to the present invention is not limited to the above configuration or the illustrated configuration. For example, the first band plate 21 and the second band plate 22 adopt an annular shape, but may adopt an annular shape. Further, for example, the support bar 3 and the tread plate 4 may be formed integrally, and it goes without saying that various improvements can be added.
