FIG. 3 is a side view of a support member constituting the trigger device according to the embodiment of the present invention. FIG. 4 is an enlarged front view showing a main part of the trigger device according to the embodiment of the present invention.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a front view of a chestnut according to this embodiment. FIG. 2 is a plan view of the chestnut according to the present embodiment. In the present embodiment, description will be given as a chestnut for catching a cocoon.

  As shown in FIGS. 1 and 2, the chestnut 10 according to the present embodiment includes a mounting table 15, a footboard 20, a trigger device 30 for operating the chestnut 10, an elastic part 40, and a beast's body. And a rope portion 25 for tightening and restraining a part of the rope.

  The mounting table 15 is made of light grooved steel having a U-shaped cross section with a predetermined length, and is placed with the opened side facing downward. On the upper surface of the mounting table 15, spring fixing rings 16 for fixing a first arm 411 of a torsion spring 41 described later are installed at two locations. In installing the chestnut 10, the chest 10 can be stably installed by embedding the mounting table 15 in the ground so that both side surfaces are buried in the ground.

  The tread plate 20 is a T-shaped plate 21 that is a T-shaped flat plate installed in the hollow ring 261, and a rod-like member fixed to the base of the T-shaped plate 21, and a swing member of the trigger device 30 described later. And a treading force transmission member 22 that transmits the treading force in contact with 31.

  The shape of the tread plate 20 can be changed to an arbitrary shape. For example, the T-shaped plate 21 and the treading force transmission member 22 may be integrally formed, or the top of the T-shaped plate 21 may be easily stepped on by a heel. A disk may be further installed in the. In other words, any shape that can transmit the pedal force to the trigger device 30 by being stepped on by a kite is acceptable.

  The rope portion 25 includes a wire rope 26 made by twisting steel strands, a stopper 27, a fastening fitting 28, and a swivel (return) 29. On the distal end side of the wire rope 26, a hollow ring 261 is formed by a fastening fitting 28 fixed to the distal end of the wire rope 26.

  When the knurled barb 10 is operated, the base side of the wire rope 26 is pulled so that the knurled ring 261 becomes smaller. Therefore, the legs of the barb located in the hung ring 261 are tightened by the wire rope 26.

  The stopper 27 is fixed at a predetermined length from the tip of the wire rope 26. The stopper 27 functions as a safety device that restricts the restriction of the cut ring 261 of the wire rope 26 to a certain size by being caught in the hole of the fastening fitting 28.

  The root side end of the wire rope 26 is fixed to a tree trunk or a pile driven into the ground where the chestnut 10 is installed. The swivel 29 is a connecting tool in which two upper and lower rings are rotatable about a vertical axis, and is installed in the middle of the wire rope 26. As a result, it is possible to prevent the wire rope 26 from being entangled when the kite restrained by the cut ring 261 is rampant.

  Next, the configuration of the trigger device 30 will be described with reference to FIGS. 3 and 4. FIG. 3 is a side view of a support member constituting the trigger device according to the present embodiment. FIG. 4 is an enlarged front view showing a main part of the trigger device according to the present embodiment, FIG. 4 (a) is a diagram showing a state in which the chestnut 10 is set, and FIG. 4 (b) is a chestnut. It is a figure which shows the state after the scissors 10 act | operates.

  The trigger device 30 is a device for operating the chestnut 10 by transmitting a pedaling force from the footboard 20. The trigger device 30 includes a swinging member 31 for releasing the locking of the elastic portion 40 in conjunction with the movement of the tread plate 20, and a support member 35 that supports the swinging member 31 so as to be swingable around the swinging shaft. , And a connecting tool 37 for connecting and locking the swinging member 31 and the elastic portion 40.

  The support member 35 is a metal member that is fixed to the upper surface of the mounting table 15 and supports the swing member 31 in a swingable manner. As shown in FIGS. 3 and 4, the support member 35 has an elongated, generally inverted U shape when viewed from the side, and is a rocking member for pivotally supporting the rocking member 31 between both side surfaces 351. A moving shaft 355 is installed. The swing member 31 is positioned between the both side surfaces 351 and is pivotally supported by the swing shaft 355.

  The swing member 31 has a wrench-like shape, and includes a substantially U-shaped U-shaped portion 311 and a handle portion 315. The upper part of the concave portion of the U-shaped part 311 in the figure is locked in a state in which the lower end side of the connector 37 is hooked and locked in order to lock the torsion spring 41, which will be described later, in a closed state. It functions as the recess 312.

  A shaft hole is formed in the projecting portion of the U-shaped portion 311 opposite to the projecting portion functioning as the locking recess 312, and the swing shaft 355 of the support member 35 is inserted into the shaft hole so that the swinging motion is performed. The member 31 can swing around the shaft hole.

  In addition, the upper half of both side surfaces 351 of the support member 35 is cut into a substantially U shape, and in the state in which the cut collar 10 is set, the coupling tool 37 hooked on the locking recess 312 is formed in this cutout portion. To position. The connection tool 37 is a connection tool for holding the torsion spring 41 so as not to open.

  In the present embodiment, a swivel is used as the connector 37. The lower ring of the connector 37 is hooked on the locking recess 312 of the swing member 31, and the upper ring of the connector 37 is passed through the second arm 412 of the torsion spring 41. Of course, as the connection tool 37, other members such as an S-can may be used as long as it is a member that can be hooked and connected to the second arm 412 and the locking recess 312.

  A horizontal pin 316 extending horizontally is installed on the side surface of the handle portion 315. In the set state of the chest 10, the treading force transmission member 22 is placed on the horizontal pin 316 as the treadboard receiving portion. The swinging member 31 is lowered and rotates counterclockwise in FIG.

  In the state where the chestnut 10 is set, the locking recess 312 of the swinging member 31 is pulled upward by the connector 37 and is in a balanced state (see FIG. 4A). On the other hand, after the tread plate 20 is stepped on, the swinging member 31 rotates counterclockwise by the pedaling force transmitted to the swinging member 31 via the pedaling force transmitting member 22, so The ring comes off from the locking recess 312 and the swing member 31 is in the state shown in FIG.

  In addition, the rotation angle of the rocking | swiveling member 31 from the set state shown to Fig.4 (a) until the coupling tool 37 remove | deviates is about 30 degrees. As described above, in this embodiment, the treading force of the kite is directly transmitted from the tread plate 20 to the swing member 31 of the trigger device 30, and the lock of the torsion spring 41 is released only by a slight rotation of the swing member 31. Can do.

  Further, in the present embodiment, in the set state of the chest 10, the horizontal pin 316 of the swing member 31 is located at a height of about 5 cm from the ground (near the upper surface of the mounting table 15), and is about a few cm horizontal pin. If 316 descend | falls, the connection tool 37 will remove | deviate from the latching recessed part 312, and the movement amount of the footboard 20 for operating the chestnut 10 will be very small. Therefore, even when the tread board is installed on the ground surface without digging a hole in the ground, it is possible to operate the hook 10 reliably.

  The elastic portion 40 provides power for tightening the round ring 261 and includes a strong torsion spring (torsion spring) 41 and a wire guide ring 43. The torsion spring 41 has a first arm 411 formed at one end of the coil spring and a second arm 412 formed at the other end. The second arm 412 is configured to be approximately 5 cm longer than the first arm 411.

  When the torsion spring 41 closes both arms 411 and 412 in the direction of winding the spring, a strong elastic force acts in the direction of opening both arms 411 and 412. In the present embodiment, a torsion spring 41 having a free angle of 135 ° and having an allowable angle of 135 ° when used in a direction in which the spring is wound is used. can do.

  In the state where the chestnut 10 is set, as shown in FIG. 1, the first arm 411 of the torsion spring 41 is inserted and fixed to the two spring fixing rings 16 of the mounting table 15, and substantially parallel to the first arm 411. The second arm 412 closed so as to be pulled by the connector 37 is pulled downward so as not to be opened. Thus, a strong elastic force is applied to the torsion spring 41 closed so that the arm angle becomes substantially 0 ° in the set state in the direction in which both arms 411 and 412 open.

  At the tip of the second arm 412 of the torsion spring 41, a wire guide ring 43 for passing the wire rope 26 described later is installed. The wire guide ring 43 is fixed to the second arm 412 so that the ring portion is substantially horizontal. As a result, when the chestnut 10 is actuated to open the second worm 412 and the tip of the second arm 412 rapidly rises, the wire rope 26 is also pulled upward by the ring portion of the wire guide ring 43. The wire guide ring 43 employs a ring structure that can be easily opened and closed. When the wire rope 26 is passed, the ring portion can be opened and passed easily.

  Further, in the present embodiment, the second arm 412 is longer than the first arm 411 by about 5 cm, and the tip of the second arm 412 provided with the wire guide ring 43 for pulling the wire rope 26 is more linear when ascending. In order to follow the trajectory ascending, the round ring 261 is also pulled up vertically, and the leg of the heel can be reliably restrained in the round ring 261. In order to obtain such an effect, the second arm 412 may be configured to be longer (4 cm or longer than the first arm 411). However, the second arm 412 is long enough not to hit the heel when the second arm 412 is raised. It is necessary to suppress it.

  The configuration of the chestnut bar 10 has been described above. Next, a method for using the chestnut bar 10 will be described. First, the kurikuri fence 10 is installed in the middle of the beast path where the fence is thought to pass. In the present embodiment, since the stroke of the tread plate 20 necessary for operating the chestnut 10 is short, it is difficult to dig a hole and it is possible to install the hammer 10.

  When installing, for safety, it is desirable to use a safety hook that holds the first arm 411 and the second arm 412 of the torsion spring 41 closed. Further, at the time of installation, if the root side portion of the swivel 29 of the wire rope 26 and the first arm 411 are fixed by a tie wire that will come off when the kite is violent, the round ring 261 is tightened. Can be performed more reliably. 1 is set, the safety hook is removed, and the chest 10 is in an operable state.

  After the installation, when the kite passes through the place where the chestnut 10 is installed and the step board 20 is stepped on with the legs, the treading force transmission member 22 is lowered together with the T-shaped board 21 due to the weight of the kite. The front end portion of the treading force transmission member 22 pushes down a horizontal pin 316 as a tread plate receiving portion formed on the swing member 31 of the trigger device 30 downward.

  When the horizontal pin 316 is lowered, the swinging member 31 rotates counterclockwise in FIG. 4, so that the lower ring of the connector 37 is detached from the locking recess 312. As a result, the locking of the second arm 412 by the connector 37 is released, so that the second arm 412 jumps up vigorously.

  When the wire guide ring 43 rises rapidly together with the second arm 412, the wire rope 26 passing through the wire guide ring 43 is also pulled upward, but there is a heel leg in the cut ring 261. Therefore, the cut ring 261 can only rise up to the torso body portion, and the wire rope 26 is pulled up by the wire guide ring 43 at the base side, and the cut ring 261 is tightened to bite into the leg of the kite. become.

  Once the tightening ring 261 is tightened, it is not easily expanded by the tightening fitting 28, and is bitten into the leg and tightened so that the heel is uncovered. Moreover, since the base side edge part of the wire rope 26 is being fixed to the tree or the pile, the cage | basket restrained by the wire rope 26 cannot escape.

  As described above, according to the present embodiment described in detail, even if the stroke of the tread plate 20 is short, it is possible to actuate the punched cage reliably, and it is possible to easily install the punched cage without digging a hole in the ground. .

  In the present embodiment, since the movement of the tread plate 20 is directly transmitted to the swing member 31 of the trigger device 30 and rotated, the structure is simple and the installation is simple. 10 can be operated and the cost can be reduced.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various deformation | transformation is possible within the range which does not deviate from the main point of this invention. For example, it is needless to say that the above-mentioned kurikuri can be applied to bears, deers and the like other than the kite.

  Moreover, the shape and size of each member constituting the chestnut can be changed as appropriate.
