Description

  The present invention relates to a hook, and more particularly to a hook for capturing wild animals such as deer and frogs.

  Conventionally, for example, those disclosed in Patent Document 1 and Patent Document 2 exist.

  Utility Model Registration No. 3172298 (Patent Document 1) has a tread plate formed to be bent downward in the center, a size capable of accommodating the tread plate, and a depth larger than the thickness of the tread plate, A base on which stepped portions capable of mounting and holding both ends are formed, and the loop is locked to the outer periphery of the tread plate to urge the tread plate toward its center, and when the lock is released, the loop is contracted An animal cage device comprising a looped wire with a spring is disclosed.

  Utility Model Registration No. 3101225 (Patent Document 2) has a tread board assembly in which two tread boards are connected so as to be foldable, and a placing table for placing the tread board assembly. Wrap the tip washer formed at one end of the capture wire rope around the outer periphery of the tread board assembly in a state maintained in the state, compress the wire rope tension spring to a predetermined position, and reduce the diameter to the tip washer When the treadle assembly is stepped on the treadle, the treadle that has been maintained in the chevron shape moves so that it has a reverse concave shape. An animal cage characterized in that it is pulled out from the tread board assembly by a rope tension spring and is narrowed down is disclosed.

Utility Model Registration No. 3172298 Utility Model Registration No. 3101225

  In Patent Document 1, when setting a saddle device, the spring is compressed in the spring compression tube and compressed by a set screw, and the spring compression tube is moved along the wire by loosening the stopper. The part is expanded and wound around the outer periphery of the tread, and the position of the spring compression tube is adjusted so that the tread is biased so as not to bend, and then fixed with a stopper. By placing the tread board on the base in this state, both ends of the tread board are locked onto the stepped portion of the base. When the animal puts its leg on the tread board, the tread board bends downward, and accordingly, the wire loop portion is released from the tread board. At this time, since the spring in the spring compression tube is extended to press the loop engaging member and reduce the diameter of the loop, the animal's leg is captured in the loop.

  Moreover, in patent document 2, when the leg of an animal steps on a tread board in the state where the cage for animals was put, both tread boards are maintained in the mountain-shaped shape by being pushed down downward. Rotate around the joint and change into a concave shape. The wire rope tip washer is urged by a wire rope tension spring so that its size is always reduced, and the force that moves from the wire rope tip washer toward the tread is accelerated. Added. As a result, the wire rope tip washer moves upward of the tread plate assembly, and when the side flange plate of the tread plate rotates upward, it comes out of the tread plate assembly and is pulled by the wire rope tension spring. It is narrowed down and the animal's leg that has stepped on the footboard is instantly tied.

  As described above, in the patent document 1 and the patent document 2, when the animal puts the leg on the tread board, the tread board is bent downward, the wire loop portion is released from the tread board, and the biasing force of the spring incorporated in the wire is used. The animal leg is captured by the wire loop.

  However, the summaries of Patent Document 1 and Patent Document 2 are not equipped with a mechanism that operates appropriately according to the weight of the capture target, so even a small animal such as a squirrel or a rabbit, such as a deer or a spider Even if it is a medium-sized animal, various types of animals will be captured. In other words, when an animal steps on the tread board, regardless of the weight of the capture target, there is a very high risk that the left and right tread boards will rotate downward and enter a capture state. May fail to capture. Thus, the conventional animal cage apparatus has a problem that it does not operate properly according to the intended weight of the animal to be captured.

  An object of the present invention is to provide a binding that is appropriately captured when a weight corresponding to an animal to be captured is added.

  A binding hook according to an embodiment of the present invention includes first and second footboards, a binding wire, and an elastic body. The first and second footboards are connected so as to be bendable. The binding wire has a binding ring that is wound around the outer circumferences of the first and second footboards, and can be biased so that the binding ring is tightened. The elastic body is bridged between the first and second footboards.

  According to this embodiment, since the first and second footboards are urged by the elastic body, when the weight corresponding to the animal to be captured is added, the binding is appropriately captured.

  The binding according to an embodiment of the present invention further includes a safety pin that is inserted into a connecting portion of the first and second footboards. In this case, if the safety pin is inserted, it is possible to prevent the first and second footboards from being bent and the binding ring from coming off.

  The binding according to an embodiment of the present invention further includes a support portion provided so as to protrude from a portion on the opposite side to the connecting portion of the first and second footboards. In this case, a hook can be installed on the hole dug in the ground.

  According to the present invention, when a weight corresponding to an animal to be captured is added, it is possible to provide a strap that is appropriately captured.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals and description thereof will not be repeated. In addition, in order to make the explanation easy to understand, in the drawings referred to below, the configuration is shown in a simplified or schematic manner, or some components are omitted. Further, the dimensional ratio between the constituent members shown in each drawing does not necessarily indicate an actual dimensional ratio.

  1 and 2, the trap 1 is a trap for capturing a medium-sized animal such as a wild deer or a shark, and mainly includes footboards 21 and 22, a rotating shaft 3, A support portion 4, a tension spring 5, a safety pin 6, a binding wire 7, and a handle 8 are provided.

  As shown in FIGS. 1 to 4, the footboards 21 and 22 are made of steel and are connected so as to be bendable.

  As shown in FIG. 3, the tread plate 21 includes a rectangular planar portion 21 a and side portions 21 b, 21 c, and 21 d that surround three sides of the planar portion 21 a. On the side surfaces 21b and 21c of the tread plate 21, a tip portion 21g protruding from the end of the flat surface portion 21a is formed on the opposite side of the side surface portion 21d.

  As shown in FIG. 3, the tread plate 22 includes a rectangular planar portion 22a and side portions 22b, 22c, and 22d that surround three sides of the planar portion 22a. On the side surface portions 22b and 22c of the tread plate 22, a tip portion 22g protruding from the end of the flat surface portion 22a is formed on the opposite side of the side surface portion 22d.

  The inner width dimension between the side surface part 22 b and the side surface part 22 c in the tread plate 22 is larger than the outer width dimension of the side surface part 21 b and the side surface part 21 c in the tread plate 21. Due to the difference in shape, the tip portion 21g of the footboard 21 and the tip portion 22g of the footboard 22 are fitted together, and the footboard 21 and the footboard 22 are connected to each other.

  Holes (not shown) are formed in the tip portion 21g of the tread plate 21 and the tip portion 22g of the tread plate 22, respectively, and overlap each other when the tip portion 21g of the tread plate 21 and the tip portion 22g of the tread plate 22 are fitted. The rotary shaft 3 is attached to the hole by bolts / nuts or rivets. The tread plates 21 and 22 are connected by the rotating shaft 3 so as to be bendable. As shown in FIGS. 4 and 7, the tread plates 21 and 22 rotate in the vertical direction with the rotation shaft 3 as a fulcrum, respectively, so that the connecting portion C of the tread plates 21 and 22 can be bent to be convex or concave. It can be changed.

  By the way, in embodiment of this invention, when the treads 21 and 22 are bent by convex shape, the front-end | tip part 21g of the tread 21 is made to contact the edge part of the plane part 22a of the tread 22 in the connection part C, and tread 21 And 22 are restricted so as not to rotate more than a predetermined angle. Due to this limitation, when the tension spring 5 is attached to the tread plates 21 and 22, the tension spring 5 can be attached at an appropriate angle while preventing the tread plates 21 and 22 from being bent more than necessary.

  Specifically, it is preferable to provide the rotation shaft 3 at an upper position near the flat surface portion 21a and the flat surface portion 22a in the vertical direction of the front end portion 21g and the front end portion 22g. Depending on the position where the rotary shaft 3 is provided, the distance from the rotary shaft 3 to the lower corner of the tip portion 21g can be longer than the distance from the rotary shaft 3 to the upper corner of the tip portion 21g. By providing this difference in distance, when the tread plates 21 and 22 are bent into a convex shape, the upper corner portion of the tip portion 21g rotates without contacting the end portion of the flat portion 22a of the tread plate 22 in the connecting portion C. Continuously, when turning to a predetermined angle, the lower corner portion of the tip portion 21g contacts the end portion of the flat portion 22a of the tread plate 22 in the connecting portion C. In this way, the tread plates 21 and 22 are restricted from rotating beyond a predetermined angle.

  Alternatively, regardless of the position where the rotary shaft 3 is provided, the tip portion 21g of the tread plate 21 extends to the lower region of the flat portion 22a of the tread plate 22 and the upper portion of the tip portion 21g of the tread plate 21 is notched. It may be in the form. If it is this form, a gap corresponding to the upper portion of the tip portion 21g is notched between the tip portion 21g and the inner surface of the flat portion 22a, and when the tread plates 21 and 22 are bent into a convex shape, The footboards 21 and 22 can be rotated to a predetermined angle corresponding to this gap. That is, when the tread plates 21 and 22 are rotated to a predetermined angle, the upper corner portion of the tip portion 21g contacts the end portion of the flat portion 22a of the tread plate 22 in the connecting portion C, and as a result, the predetermined angle or more. Therefore, the tread plates 21 and 22 are restricted from rotating.

  The footboards 21 and 22 include a support portion 4 that is provided so as to protrude from a portion on the opposite side to the connecting portion C.

  Specifically, as shown in FIG. 4, the support portion 4 is provided on each of the side surface portion 21 d of the tread plate 21 and the side surface portion 22 d of the tread plate 22. The support portion 4 provided on the side surface portion 21d of the tread plate 21 is provided so as to protrude toward the outside of the side surface portion 21b and the side surface portion 21c of the tread plate 21. The support portion 4 provided on the side surface portion 21d of the tread plate 22 is provided so as to protrude toward the outside of the side surface portion 22b and the side surface portion 22c of the tread plate 22.

  In addition, the support part 4 by embodiment of this invention employ | adopts the thing of steel round bar shape, and is welded and attached to the steel treads 21 and 22. FIG.

  By the way, if it is the conventional roundabout, the base which supports a tread will be provided, and it has the form which installs the base directly on the ground G. However, in such a conventional form, the trapezoid itself is raised from the ground G, so that medium-sized animals such as deer and traps to be captured are regarded as obstacles, There is a risk of being easily avoided. On the other hand, the narrow band 1 according to the embodiment of the present invention is directly supported on the ground G around the hole H by the support portion 4 fixed to the tread plates 21 and 22 without having a pedestal. Therefore, the hook itself does not rise from the ground G, and the probability of capturing a medium-sized animal such as a deer or a spider that is a capture target is increased.

  In addition, since the narrow hook 1 according to the embodiment of the present invention adopts a relatively simple configuration of the round bar-like support portion 4 fixed to the tread plates 21 and 22, compared with a conventional product separately provided with a pedestal, Manufacturing costs can also be kept low.

  The tension spring 5 functions as an elastic body that generates an urging force in a direction toward the connecting portion C of the footboards 21 and 22, and includes a spring portion 51 and retaining ring portions 52 formed at both ends thereof. Become. As shown in FIGS. 3 and 4, the tension spring 5 is mounted so as to span the tread plates 21 and 22.

  More specifically, in the upper tension spring 5 shown in FIG. 3, the retaining ring portions 52 formed at both ends thereof are provided on the hook 21 f provided on the side surface portion 21 b of the tread plate 21 and the side surface portion 22 b of the tread plate 22. The hooks 22f are respectively hooked and mounted so as to be bridged over the tread plates 21 and 22.

  Similarly, with respect to the lower tension spring 5 shown in FIG. 3, the retaining ring portions 52 formed at both ends thereof are provided on the hook 21 f provided on the side surface portion 21 c of the tread plate 21 and the side surface portion 22 c of the tread plate 22. The hooks 22f are respectively hooked on the hooks 22f and mounted on the tread plates 21 and 22.

  As shown in FIG. 4, the tread plates 21 and 22 with the tension springs 5 are preferably in a state where the connecting portion C is stationary with a convex shape protruding slightly upward. In this convex resting state, the force that tries to move in the outward direction due to the connecting portion C of the tread plates 21 and 22 falling in the direction of gravity and the direction toward the connecting portion C of the tread plates 21 and 22 by the tension spring 5 It is in a state where it is balanced with the urging force.

  The tread plates 21 and 22 are maintained in a convex stationary state by attaching the tension spring 5. For this reason, even when a weight corresponding to a small animal that is not to be captured such as a squirrel or a rabbit is added to the tread board 21 and the tread board 22, or when the tread board 21 and the tread board 22 are pushed down slightly due to malfunction or the like, The balance of the resting state in the treads 21 and 22 is not disturbed, and unless the appropriate weight corresponding to the target medium-sized animal such as a deer or a spider is added, the constriction 1 does not easily enter the captured state by mistake. ing.

  That is, when a weight equivalent to a medium-sized animal such as a deer or a spider is added to the treads 21 and 22 with the tension springs 5 attached, the balance of the treads 21 and 22 in a stationary state is lost, and the narrowing 1 is activated. Due to the urging force of the tension spring 5, the connecting portion C of the tread plate 21 and the tread plate 22 falls down vigorously. As described above, the binding 1 is instantaneously shifted to a state in which the connecting portion C of the footboards 21 and 22 is recessed, that is, to the capture state.

  The tension spring 5 can be easily detached from the hooks 21f and 22f of the footboard. For this reason, the weight of the animal to be captured is estimated in advance, and various conditions that affect the elastic force of the tension spring 5 such as the spring alignment, the number of turns, and the material are set. By replacing the spring 5 with the tread plates 21 and 22, it is possible to appropriately use the strap 1 suitable for the capture target.

  Holes 21e are formed in the side surface portion 21b and the side surface portion 21c formed on both sides of the tread plate 21, respectively, below the rotation shaft 3. Similarly, holes 22e are formed in the side surface portion 22b and the side surface portion 22c formed on both sides of the tread plate 22 below the rotation shaft 3, respectively. The holes 21e and 22e are for inserting the safety pin 6. In the stationary state of the footboards 21 and 22 shown in FIG. 4, the hole 21e and the hole 22e are overlapped, and at this position, the safety pin 6 is inserted into the overlapped holes 21e and 22e. Thereby, during the operation | work which winds the ring 71 of the binding wire 7 mentioned later around the outer periphery of the stepping plates 21 and 22 whole, malfunctioning of the stepping plates 21 and 22 can be prevented.

  The safety pin 6 can be appropriately selected from various materials such as steel and wood.

For example, if a wooden safety pin such as a toothpick is used, the hook 1 is activated and the footboards 21 and 22 fall downward, and the wooden safety pin is easily broken, so in the operation of the hook 1 There will be no significant impact. For this reason, if it is a wooden safety pin, there exists an advantage that it is not necessary to remove especially after a winding operation | work.

  In addition, considering the weight of the animal to be captured and the folding condition of the wooden safety pin, the number of wooden safety pins (such as toothpick) inserted into the holes 21e and 22e in advance is set to be plural. Fine adjustment of the weight at which 1 operates is also possible in advance.

  As shown in FIGS. 2 and 4, when the stepping plates 21 and 22 are in a stationary state, the binding 1 is activated by winding the binding ring 71 of the binding wire 7 around the outer periphery of the stepping plates 21 and 22. As shown in FIG. 5, the binding wire 7 is composed of a long metal wire 7a. A binding ring 71 is formed at one end of the wire 7a, and a fixed ring 72 is formed at the other end. Is formed.

  The ring 71 is formed in a state in which a fastener 74 fixed to one end of the wire 7a is hooked on a movable fastener 75 attached to the wire 7a. The size of the ring can be expanded and contracted by adjusting the position of the fastening bracket 75 with respect to the wire 7a.

  The compression spring 73 is a coiled spring formed long along the longitudinal direction of the wire 7a, and is attached to the binding wire 7 while being inserted through the wire 7a. This compression spring 73 acts to push the fastening metal fitting 75 in the direction of the metal fitting 74 by the outward elastic force against the contracted state and to reduce the size of the ring 71.

  As shown in FIG. 5, the adjustment fitting 76 is a fitting having a hat shape made up of a cylindrical portion 76a and a flange portion 76b, and is attached to the binding wire 7 while being inserted into the wire 7a. The adjustment fitting 76 is attached to the binding wire 7 between the compression spring 73 and the fixed ring 72 while being inserted through the wire 7a. The adjustment fitting 76 can move freely with respect to the wire 7a in a state where the adjustment fitting 76 is not fixed with a wing screw 77 described later.

  The wing screw 77 is screwed into the screw hole (not shown) of the cylindrical portion 76a of the adjustment fitting 76 in the direction of the wire 7a.

  The adjustment fitting 76 is fixed to the wire 7a when the tip of the thumbscrew 77 is screwed into the wire 7a when the thumbscrew 77 is screwed. Thus, the wire 7a is adjusted to an appropriate position, and the adjustment fitting 76 can be fixed at that position.

  The compression spring 73 is compressed by being pressed in the direction of the binding ring 71 using the adjustment fitting 76 before being fixed by the thumbscrew 77. If the adjustment fitting 76 is fixed to the wire 7a with the thumbscrew 77 when the compression spring 73 is in the compressed state, the elastic force in the compressed butterfly spring 73 can be adjusted at the position of the fixed adjustment fitting 76. .

[how to use]
Hereinafter, the usage method of the narrow band 1 by embodiment of this invention is demonstrated.

  First, the tension spring 5 is attached to the tread plates 21 and 22. Specifically, in one tension spring 5, the retaining ring portion 52 is hooked on the hook 21 f provided on the side surface portion 21 b of the tread plate 21 and the hook 22 f provided on the side surface portion 22 b of the tread plate 22.

  Similarly, with respect to the other tension spring 5, the retaining ring portions 52 formed at both ends thereof are respectively connected to the hook 21 f provided on the side surface portion 21 c of the tread plate 21 and the hook 22 f provided on the side surface portion 22 c of the tread plate 22. Hook.

  At this time, as shown in FIG. 4, the tension springs 5 are attached to the tread plates 21 and 22 so that the connecting portion C stops in a convex state protruding slightly upward.

  After attaching the tension springs 5 to the treads 21 and 22, a hole H having an appropriate size is dug in the ground G to be captured, and the tread plate 21 and the tread board 22 are installed immediately above the hole H. At this time, the support portion 4 provided on the footboards 21 and 22 is installed so as to be directly supported by the ground G around the hole H.

  After installation of the footboards 21 and 22, the safety pin 6 is inserted into the hole 21 e of the footboard 21 and the hole 22 e of the footboard 22 when the footboard 21 and the footboard 22 are stationary.

  At this time, it is only necessary to insert one safety pin 6 into one of the holes 21e and 22e of the side surface portion 22b or the side surface portion 22c, but the two safety pins 6 are used to connect the side surface portion 22b and the side surface portion 22c. One hole may be inserted into each of the holes 21e and 22e.

  Next, in a stationary state of the footboards 21 and 22, the binding ring 71 of the binding wire 7 is lightly wound around the outer periphery of the footboards 21 and 22.

  Thereafter, the insertion portion 82 of the handle 8 is inserted into the wire 7a in the vicinity of the adjustment fitting 76 provided at the end of the compression spring 73 of the binding wire 7, and the holding ring 71 of the binding ring 71 is held with the gripping portion 81 of the handle 8 held by hand. Pull in the direction. After confirming that the binding ring 71 is wound around the outer peripheries of the footboards 21 and 22 and tightened tightly, a thumbscrew 77 is fastened to the adjustment fitting 76 to hold the winding state, and the adjustment fitting 76 is fixed to the wire 7a. To do.

  By this operation, the compressed spring 73 can be maintained in a compressed state, and as a result, the binding ring 71 is in a contracted state in which the binding ring 71 is tightly wound around the tread plates 21 and 22.

  If an external handle 8 is used at the time of this winding operation, the handle 8 does not remain on the binding wire 7 after the operation, the appearance of the neckline 1 is clean, and even at the time of another neckline 1 operation. The handle 8 can be reused. In addition, since the handle 8 is formed with the gripping portion 81, the operator's force can be appropriately applied to the handle 8 during the winding operation, and the operator's pulling force can be applied via the handle 8. Since it acts on the compression spring 73 of the binding wire 7, the winding operation of the binding ring 71 around the tread plates 21 and 22 is simplified, and the efficiency of the operation can be improved.

  After the binding ring 71 of the binding wire 7 is firmly wound around the outer peripheries of the tread plates 21 and 22, the safety pin 6 is removed from the holes 21e and 22e.

  Finally, the fixing ring 72 formed at the end of the wire 7a is attached to a surrounding tree or the like, and the entire binding 1 is covered with surrounding dead leaves, soil, etc., so that the installation work of the binding 1 is completed. .

  When a leg L of a wild animal such as a deer or a moth steps on the treads 21 and 22, the narrow band 1 instantaneously shifts from the stationary state in the upper diagram in FIG. 7 to the captured state in the lower diagram in FIG. The connecting portion C of the footboards 21 and 22 is bent downward with the rotating shaft 3 as a fulcrum.

  More specifically, the leg L of a wild animal such as a deer or a moth steps on the treads 21 and 22, and at the same time, the balance of the treads 21 and 22 in the stationary state by the tension spring 5 is lost, and the inward direction by the tension spring 5 Due to this urging force, the connecting portion C of the footboards 21 and 22 is momentarily bent downward with the rotating shaft 3 as a fulcrum, and wild animals such as deer and frogs fall into the hole H.

  Simultaneously with this operation, the ring 71 is detached from the outer peripheries of the treads 21 and 22, and the ring 71 is momentarily contracted by the action of the urging force of the compression spring 73 attached to the ring 71, thereby causing deer, sharks, etc. The ring 71 is fastened to the leg L of the wild animal.

  As described above, the narrowing 1 according to the embodiment of the present invention includes the tension spring 5 for appropriately operating according to the weight of the capture target, so that the capture target animal steps on the narrowing 1. In this case, the footboards 21 and 22 are rotated downward to enter the capturing state, and the animal to be captured can be reliably captured.
