Description

  The present invention relates to a animal foot clipper used for capturing beasts such as sharks, deer, and bears that live in Yamano.

  In recent years, the aging and depopulation of farming and mountain villages has progressed, satoyama has been devastated, abandoned farming land has increased, and beasts such as foxes, deer and bears have appeared more in the village than ever before, eating and destroying crops, In addition to causing harm to people, human life is often lost. As a trap to catch such beasts, a trap has been set up that has been difficult for the animal path, and the beast leg has been trapped by a ring-shaped cutout. At that time, in order to install a cut-out trap, for example, dig a hole deep enough for the beast to step into the beast path, insert several short twigs into the inner wall of the hole, pass it sideways, and place it on the cross. A ring-shaped cutout provided on the tip of the trapezoid body that is difficult to move on the periphery of the hole after putting the animal foot detection lines several times and tying each tip to a dead branch or grass inserted on the periphery of the hole. It is used as a camouflage by covering it with fallen leaves or soil.

  Then, the rear end of such a beast foot detection line is tied to a retaining ring for stopping a lock / release safety pin provided in the safety device of the narrow body. Then, when the beast's stepping foot enters the hole and a load of the animal foot is applied to the animal foot detection line, the line falls into the bottom of the hole, and the rear end of the line is pulled forward. As a result, the retaining ring moves forward. Therefore, the safety pin that fits in the retaining ring is removed, the safety device is unlocked, and the coil spring that is in the compressed state is released. By using the spring force to tighten the ring, , You can capture the animal foot.

However, simply digging a hole in the beast road and installing a trap that is difficult to prevent the surrounding wall of the hole from collapsing due to rain, snow, etc. Management is required. In view of this, there has been proposed a hook using a cylinder embedded in the ground and provided with a flat plate such as a net that can move downward when a load is applied by the foot of a beast.

Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS.
FIG. 1 is a plan view showing a state in which a animal foot detection line is stretched in a work-in-process cylinder device for animal foot holes to which the present invention is applied, and FIG. 2 is a right side view thereof. This in-process cylinder device 1 is used together with a knurled main body to constitute a beast-footed knurled. A cylinder having upper and lower openings 3 (3a, 3b), for example, a cylinder made of vinyl chloride having a height of 13.5 cm, an inner diameter of 15.5 cm, and an outer diameter of 16.5 cm is used as the work-in-process cylinder 2. Then, the upper opening 3a of the work-in-process cylinder 2 can be used as a capture opening into which the foot of the beast enters.

  Therefore, in order to detect the animal foot fitted in the work-in-process cylinder 2, a plurality of animal foot detection lines 4 to which the load of the animal foot is applied are used, for example, four, and the adjacent lines 4 are separated from each other. The front end of each animal foot detection line 4 (4a,... 4d) is fixed to the front side wall of the in-process cylinder 2, and the rear end portion of each animal foot detection line 4 is provided in the rear side wall of the in-process cylinder 2. Through holes 5 (5a,... 5d) to be pulled out to the outside, and the vicinity of the rear ends thereof are combined together, and the rear end connecting portion 6 is not connected to the rear end connecting portion 6 and the punching portion provided at the front end of the narrow body A start trigger member 7 is provided.

  At that time, for example, a wire rope having a length of 30 cm and a thickness of 0.4 mm is used as the animal foot detection line 4. Then, in order to fix the tips of the four animal foot detection lines 4 to the front side wall of the work-in-process cylinder 2, each animal foot detection line 4 first passes through a half of the height of the front side wall. Four through-holes 8 (8a,... 8d) are drilled, and each of them is distributed two by two so that the adjacent holes 8 are 6 cm apart and left and right symmetrical. Next, the tip of each animal foot detection line 4 is inserted into the corresponding through hole 8 and protrudes slightly outside the front side wall, and there is a crimp sleeve 9 (9a,... 9d) as a retaining member for fixing there. Are fixed respectively.

  In addition, in order to draw the rear end of each animal foot detection line 4 to the outside through the rear side wall of the work-in-process cylinder 2, the four animal foot detection lines 4 first pass through the half of the height of the side wall. The through small holes 5 are perforated, and in each case, two adjacent holes 5 are distributed at intervals of 1.5 cm so as to be symmetrical. Next, the rear end portion of each animal foot detection line 4 is inserted into the corresponding through hole 5 and pulled out to the outside. Therefore, a crimping sleeve 10 is fixed as a coupling member for coupling the vicinity of the rear end of each animal foot detection line 4 together, and a ring 11 is provided on the rear side of the crimping sleeve 10 of the rear end coupling portion 6. Then, one end of one wire having a length of, for example, about 18 cm is twisted and coupled to the ring 11 and can be used as the trigger member 7 for starting the winding operation.

  Further, a trapping support member 12 is provided at the center of the outer surface of the rear wall of the work-in-process cylinder 2. At that time, for example, a support body 13 made of a wire bent in a substantially L shape as a trapping support member 12 and a vertical portion 14 having a length of 9.5 cm along the outer surface of the rear wall of the work-in-process cylinder 2 of the support body 13 are arranged.

A wire-coupled body having a thickness of 3.2 mm, comprising a wire installation receiving portion 17 made of wire having a length of 5 cm and crossed and joined to the tip of the portion 16 in a cross shape, is used. Although both the anti-rotation portion 15 and the trapping receiving portion 17 are bent in an arc shape, the anti-rotation portion 15 is slightly bent in accordance with the curvature of the outer surface of the peripheral wall of the work-in-process cylinder 2, whereas The part 17 is lowered at the center, and the left and right ends are bent slightly forward and upward.

  Then, the lower end of the vertical portion 14 of the L-shaped support body 13 is fixed to the rear wall of the work-in-process cylinder 2 by using a crimping sleeve 18 with a ring portion, a bolt 19, a nut 20, a washer 21, and the like, and the vertical portion 14 The upper end of the wire is fixed using a wire 22. Then, the height of the tip of the support body 13 can be held slightly lower than the height of the upper edge of the work-in-process cylinder 2, for example, about 1 cm, and the trapping receiving portion 17 can be placed on the tip and fixed. The center of the upper edge of the rear wall of the work-in-process cylinder 2 is cut out in an arc shape having a width of about 4 cm and a depth of about 1 cm, and a recess 23 is provided for smoothly performing the cutting operation.

  Thus, when the in-process cylinder apparatus 1 is completed, the structure of the apparatus can be simplified and unitized. Normally, as shown in FIG. 3, the portion near the rear end coupling portion 6 of the four animal foot detection lines 4 is handled by being placed on the trapping receiving portion 17.

  Therefore, as a cylinder lid 24 for closing the upper opening 3a of the work-in-process cylinder 2, a disk body 25 having an outer diameter of 15 cm, for example, which is slightly smaller than the inner diameter of the work-in-process cylinder 2 as shown in FIG. In addition, a circular plate body including a plurality of cut-out portion receiving fan-like projections 26 provided so as to protrude, for example, 2.5 cm in the plate surface direction is used. And the outer peripheral part except the center part 27 of the disk body 25 is divided into a large number in a radial pattern. For example, it divides into 8 parts, and each division part 28 (28a, ... 28h) is made into the slit shape of length 5cm, respectively, and the eight fan-shaped division parts 29 (29a, ... 29h) are formed. In addition, a plurality of cut-out portion receiving fan-shaped projections are arranged in the fan-shaped divided portions 29 arranged in a circle. For example, each of the divided portions 29a, 29c, 29e, and 29g is provided with a cut-out portion receiving fan-shaped protrusion 26 (26a,... 26d) on each semi-peripheral surface. Further, one or a plurality of drain holes 30 are provided in the central portion 27 of the disc body 25. For example, a through hole having a diameter of 5 mm is provided at one location in the center of the central portion 27 and one location at the base of each divided location 28. Then, the cylinder lid 24 is completed. Note that a veneer plate having a thickness of 2.5 mm is suitable as the material of the tube lid 24.

  When capturing a beast using such a work-in-progress cylinder device 1, a tube lid 24, and a hollow main body, a hole 31 for installing the work-in-process cylinder device 1 is dug in the beast path. Then, as shown in FIG. 5, the in-process cylinder device 1 is placed inside the installation hole 31, and the upper edge of the in-process cylinder 2 is placed about 1 to 2 cm below the ground surface. Therefore, in order to cover the in-process cylinder 2 with the cylinder lid 24, first, the separation member 32 is inserted into the division portion 28 of the cylinder lid 24, and the plane of the division part 29 having all the cut-out part receiving projections 26 and all the projections are inserted. It is biased so that a step is formed between the plane of the divided portion 29 that is not present. At that time, as the separating member 32, for example, four rod-like bodies obtained by cutting a dead twig or the like into a predetermined length are used, and each of the rod-like bodies 32 (32a,... 32d), as shown in FIG. It is preferable to place them on the split portions 29 without protrusions, insert both ends into the slit-shaped split portions 28, and insert them below the split portions 29 with the cut-out portion receiving protrusions 26 on both sides.

  Then, the cylinder cover 24 is put on the work-in-process cylinder 2, and the upper opening 3a of the work-in-process cylinder 2 can be closed. In addition, all the cut-out portion receiving projections 26 provided on the cylinder lid 24 get over the upper edge of the work-in-process cylinder 2 and protrude outward, respectively, and all the divided portions 29 without any projections are slightly inward from the upper opening 3a. Can be dropped and fitted. Therefore, when the cylinder lid 24 placed on the work-in-process cylinder 2 is not displaced, the closed state is stable, and when the hanger portions 33 are placed on all the cut-out portion receiving projections 26 and arranged in a circular ring shape, The cut-out portion 33 can be accurately positioned with respect to the upper opening 3a of the work-in-process cylinder 2. In this way, after the in-process cylinder 2 is covered with the cylinder lid 24, the soil is placed around the cylinder. However, soil should not be put near the trapping support member 12 provided on the outer wall of the rear wall of the work-in-process cylinder 2.

  Therefore, as the narrow body 34, a ring-shaped cut portion 33 that can be contracted / expanded by using a front end harder 35 or the like is provided, and a rear end portion is used as a place to be tied to a standing tree or the like. The capture steel rope 36, a compression coil spring (not shown) through which the capture rope 36 is inserted, and the capture rope 36 are inserted so that the compression coil spring is fully accommodated when locked and partially accommodated when released. A device in which a front and rear pipes 38 and 39 that can be fitted and separated with a safety device 37 are combined is used. The front pipe 38 has a compression coil spring tip stop portion inside the front end thereof, receives the spring force when the safety device 37 is released, and contracts the forward moving mechanism and moves backward against the spring force. The rear tube 39 has a rear end stop portion of the compression coil spring inside the rear end thereof, whereas the rear tube 39 cannot move backward by a rear stop (not shown) fixed to the capture rope 36. This is a fixing tube.

When the cut-out main body 34 is installed, the cut-out portion 33 is first hung on a place where it cannot be easily removed, such as a track rope. Then, the separated moving front pipe 38 is drawn toward the fixing rear pipe 39, the coil spring is compressed against the spring force, and the vicinity of the rear end portion of the moving front pipe 38 is fixed after fixing. The two pipes 38 and 39 are assembled by fitting into the front end portion of the pipe 39. Therefore, in order to bring the safety device 37 into the locked state, as shown in FIG. 7, the rear end bent so as to be rotatably supported by the front end ring 41 of the thin rear wire rope 40 coupled to the front end of the fixing rear tube 39. The flat rear end portion 43 of the safety pin 42 is put into a rear end wheel 45 of a thin front wire rope 44 coupled to the front end portion of the moving front tube 38, and the rod-shaped front side portion 46 of the safety pin 42 is connected to the front rope 44. Make parallel. Next, the front side portion 46 of the safety pin 42 is inserted into a pin retaining ring portion 48 having a front end annular portion 47 through which the front rope 44 is freely inserted, and the pin retaining ring portion 48 with the distal end ring portion 47 is moved backward. Then, the vicinity of the pinned ring portion 48 is fixed using a gum tape or the like so that the safety pin 42 does not come off. Then, the safety device 37 is locked. Reference numerals 49 and 50 denote crimping sleeves for forming the rear side, the front ends of the front ropes 40 and 44, and the rear end rings 41 and 45, respectively.

  Therefore, the rear end of the catching rope 36 is wound around a nearby tree, and a series of front and rear pipes 38 and 39 with the safety device 37 locked are pulled out from the rear end of the catching rope 36, and the cut-out main body 34 is fixed. To do. Next, the rope 36 of the rounded portion 33 is expanded so as to be slightly larger than the outer diameter of the work-in-process cylinder 2, and the rear stopper is moved immediately after the fixing rear pipe 39 to fix the thumbscrew. Thereafter, when the four animal foot detection lines 4 are put on the receiving portion 17 of the trapping support member 12 provided on the work-in-process cylinder 2 and pulled backward with the vicinity of the rear end coupling portion 6 and the like, By pulling the animal foot detection line 4, it can be satisfactorily stretched inside the work-in-process cylinder 2. Therefore, the wire used as the cutting operation start trigger member 7 may be coupled to the safety device 37 of the hollow body 34 while maintaining the stretched state, and the installation work can be performed easily.

  Further, the front end portion of the moving front tube 38 is placed on the receiving portion 17 of the trapping support member 12, and the hollow portion 33 protruding from the front tube 38 is placed on all the hollow portion receiving protrusions 26 of the tube lid 24. And expand it into a circular ring. Thus, when the portion near the rear end coupling portion 6 of each animal foot detection line 4 and the front end portion of the moving front tube 38 constituting the hollow body 34 are placed on the receiving portion 17, a trigger member for starting the necking operation. The wire used as 7 can be more easily coupled to the safety device 37 of the cut-out main body 34, and the animal foot cut-out can be easily and satisfactorily installed. When the cut-out portion 33 is arranged in a circular ring shape, the dead twigs are folded short, and the necessary number of branches, for example, each of the five twigs 51 are dispersed in the vicinity of the outer periphery of the work-in-process cylinder 2 to the ground. Stand up.

  In this way, after expanding the cut-out portion 33, the tube cover 24 and the rope 36 of the cut-out portion 33 are covered with soil or fallen leaves. Therefore, the gummed tape is peeled off from the vicinity of the pinning ring part 48, the tip of the wire used as the trigger member 7 for starting the cutting operation is passed through the tip ring part 47 of the pinning ring part 48, and the tip part of the safety pin 42 is pinned. After the pinned ring portion 48 is moved to a position that protrudes about 5 mm beyond the end of the ring portion 48, the wire 7 is bent and further covered with fallen leaves or the like so that the continuous front and rear tubes 38 and 39 that are partially fitted are not visible. This completes the installation of the beast foot clippers.

  After such a beast-legged installation, even if it is raining or snowing, the surrounding wall of the in-process cylinder 2 becomes a barrier and it is difficult for earth and sand to enter the inside. Further, even if the through holes 5 and 8 provided in the work-in-process cylinder 2 are made large enough not to interfere with the tension and relaxation of the inserted animal foot detection line 4, the holes 5 and 8 are matched to the thickness of the line. Therefore, it is difficult for dirt and the like to enter the cylinder from the holes 5 and 8. In addition, since the cylinder lid 24 is provided with a large number of drain holes 30, it is natural that water easily falls into the cylinder through each hole 30, and deformation such as the cylinder lid 24 being bent due to the weight of the water does not occur. . Therefore, there is no need for a patrol for care after rough weather, the number of patrols can be reduced, and management can be performed easily.

  When the stepping foot of the beast gets on the tube lid 24 and the load of the beast foot is applied to the tube lid 24, the divided portions 29a, 29c, 29e, 29g with the four cut-out portion receiving projections 26 are all at the root. Each of the plate portions is bent and the plate surfaces are inclined, and the base portions on the inner side are faster than the receiving protrusions 26 on which the cut-out portions 33 ride, and the divided portions 29b, 29d without the central portion 27 and the protruding portions around it are provided. It falls into the work-in-process cylinder 2 together with 29f and 29h. Therefore, the four animal foot detection lines 4 stretched inside the work-in-process cylinder 2 are satisfactorily made by the central portion 27 of the tube lid 24 and the divided portions 29b, 29d, 29f, and 29h having no protrusion. Can be pushed down. Note that each of the divided portions 29 with the protrusions 26 has slit portions 28 on both sides thereof, and water drain holes 30 are provided at the bases thereof, so that the base portions are weak and bend at the positions. easy.

  In this way, when the animal foot detection line 4 is pushed down by the tube lid 24, the pin retaining ring portion 48 of the safety device 37 is pulled by the wire serving as the trigger member 7 for starting the cutting operation provided in the rear end coupling portion 6 thereof. And move forward. Then, the safety pin 42 rotates and the rear end portion 43 comes off from the wheel 45, the safety device 37 is released, and the moving front pipe 38 is moved forward along the catching rope 36 by the spring force of the compression coil spring. Moving. For this reason, it is possible to keep pushing the punching tool 35 at the front end of the moving front tube 38, and the punching part 33 contracts rapidly. Therefore, you can quickly grab the foot of the beast you stepped on and capture it.
