Description

  The present invention relates to a small animal trap used to capture small animals such as mice.

  Conventionally, in order to capture small animals such as mice, for example, as shown in Patent Document 1 below, a small animal capturing box using a seesaw plate has been provided. In this small animal capture box, when the shark enters the back of the center of the seesaw, the back side of the seesaw slightly lowers due to its weight. Then, since the rotating shaft is separated downward, the balance is lost, the back side is lowered to the bottom all at once, and is fixed by the attractive force of the magnet at the bottom of the seesaw and the magnet at the bottom of the box. In this state, the seesaw entrance is blocked so that the kite cannot escape.

Utility Model Registration No. 3113786

  The small animal capture box is fixed by the magnetic attraction when the back side of the seesaw is lowered at once. For this reason, there is a problem that if the captured small animal is surprised and begins to rampage, the magnet will come off and the captured small animal will escape. On the other hand, small animals such as rabbits have a long tail, and about 1/2 of the body length is occupied by the length of the tail. Therefore, when the seesaw's back side is lowered all at once, the tail of the heel or the like is caught between the seesaw and the entrance before the seesaw is fixed by the magnet's attractive force, and a gap is created between the magnets. It cannot be fixed sufficiently. On the other hand, heels, etc., feel strange when they are caught in their tails, so if the heels reverse in this state, the seesaw can easily be returned to the original and the sharks in the box easily There is a problem of being able to escape.

  The present invention has been made to solve the above problems, and an object of the present invention is to provide a small animal trap that can reliably capture a small animal without escaping.

In order to achieve the above object, the small animal trap of the present invention is a small animal trap that captures a small animal that has entered through the inlet by closing the inlet formed in the capture container.
In the capture container, a seesaw plate is provided so as to face the entrance,
The seesaw plate is configured to incline toward the back when the small animal that has entered from the entrance moves to the back, and the entrance to the entrance with the small animal that has entered from the entrance has moved to the back and inclined toward the back. Configured to close,
A lock mechanism that holds and locks the inclined state of the seesaw plate that is inclined downward toward the back,
The locking mechanism includes a locking piece that is provided on the seesaw plate and moves up and down inside the capture container, and a locking means that locks the locking piece inside the capture container and locks the seesaw plate. Configured,
The gist of the invention is that the locking means has a release portion that is exposed to the outside of the capture container and can release the locking of the locking piece from the outside of the capture container.

According to the small animal trap of the present invention, since the lock mechanism that holds and locks the inclined state of the seesaw plate inclined toward the back, when the small animal enters from the entrance and moves to the back, When the seesaw plate is tilted toward the back, the seesaw plate is locked by the locking mechanism, so that even if the captured small animal goes wild, it cannot escape.
The locking mechanism includes: a locking piece provided on the seesaw plate that moves up and down inside the capture container; and a locking means that locks the seesaw plate by locking the locking piece inside the capture container. It is configured to include. Thus, since the locking piece moves up and down inside the capture container and the locking means is configured to lock the locking piece inside the capture container, the small animal comes into contact with the outside of the capture container. There is no risk of the lock mechanism being destroyed by external force.
Further, the locking means has a release portion that is exposed to the outside of the capture container and can release the lock of the locking piece from the outside of the capture container, and the release of the lock after capturing the small animal is captured. It can be carried out from the outside of the container and is very convenient for repeated use.
In addition, a presser plate that inclines the seesaw plate toward the back with a weight when an invading small animal rides is placed on the back side end of the seesaw plate, and the back side end of the presser plate is hinged Because it is fixed,
The seesaw plate is difficult to move until the small animal passes through the shaft of the seesaw plate for a while, and the presser plate can be moved little up and down when the seesaw plate performs the seesaw motion. For this reason, it is less likely that small animals with strong vigilance are wary of a slight tilt of the scaffold. And since the seesaw plate is inclined and locked when the animal moves to the back side until the small animal can no longer escape, the escape of the small animal is greatly reduced.

  In the present invention, the lock mechanism is configured to hold and lock the seesaw plate in an inclined state in two steps, a first step in which the seesaw plate forms a gap with the inlet and a second step in which the inlet is closed. If the seesaw plate is tilted toward the back when a small animal invades from the entrance and moves to the back, the seesaw plate is first in the first stage to create a gap between the entrance and the entrance. Locked. At this time, the tail of the small animal is not pinched by the seesaw plate by the gap, and since the seesaw plate is locked in this state, it cannot escape from the box. Next, when the small animal advances further back after being housed in the capture container up to the tail, the seesaw plate is locked in the second stage of closing the entrance, so that the small animal that has entered is completely captured in the capture container. Is done.

In the present invention, in the upper part of the entrance of the capture container, when a notch that prevents the tail of a small animal entering the capture container from the entrance from being sandwiched between the seesaw plate and the capture container is formed, When the small animal invades from the entrance and moves to the back, the seesaw plate is tilted toward the back and locked by the locking mechanism, the tail of the small animal will not be caught by the seesaw plate by the above cutout. Since the seesaw plate is locked in the state, it is not possible to escape from the box, and the small animal that enters is completely captured in the capture container.

It is sectional drawing which shows the whole structure of the small animal trap in 1st Embodiment of this invention. It is a figure which shows the said small animal trap. It is sectional drawing explaining operation | movement of the said small animal trap. It is sectional drawing explaining operation | movement of the said small animal trap. It is sectional drawing explaining operation | movement of the said small animal trap. It is a principal part enlarged view explaining operation | movement of the said small animal trap. It is a figure which shows the principal part of the small animal trap in 2nd Embodiment of this invention.

  Hereinafter, embodiments of the small animal trap of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a cross-sectional view showing the overall structure of a small animal trap in the first embodiment, FIG. 2 (A) is a perspective view of the whole, and FIG. 1 (B) is a perspective view showing the main part of a seesaw plate. ) Is a perspective view showing the main part of the locking means.

  This small animal trap captures small animals that have entered through the inlet 2 by closing the inlet 2 formed on the lateral surface of the capture container 1. In the figure, reference numeral 9 denotes a bait 9 for attracting small animals.

  More specifically, the capture container 1 is formed in a rectangular parallelepiped shape extending in the front-rear direction, and an inlet 2 is opened below the front wall surface. A seesaw plate 3 is provided in the capture container 1 so as to face the inlet 2. The seesaw plate 3 can perform a seesaw motion that pivots back and forth in a seesaw manner by a shaft 4 provided over the left and right wall surfaces.

  The seesaw plate 3 is set so that the entrance 2 side is long and the back side is short with respect to the shaft 4, and a bottom plate 5 is provided at the back end of the seesaw plate 3. In addition, a presser plate 7 that inclines the seesaw plate 3 toward the back with a weight when an invading small animal rides is placed on the back end of the seesaw plate 3. The end portion is hinge-fixed by a hinge fixing portion 8 so as to be rotatable up and down.

  With such a structure, the seesaw plate 3 is inclined upward from the entrance 2 side in the initial state until the small animal that has entered from the entrance 2 moves on the seesaw plate 3 and rides on the presser plate 7. By proceeding, the presser plate 7 rotates downward about the hinge fixing portion 8 by the weight of the small animal and presses the back end of the seesaw plate 3 downward. As a result, the seesaw plate 3 is balanced so as to incline toward the back by rotation by the seesaw motion. That is, the seesaw plate 3 is configured to incline toward the back when the small animal that has entered from the entrance 2 moves to the back.

  The hanging plate 5 functions as a weight when the seesaw plate 3 performs the seesaw motion described above, and the seesaw plate 3 moves too much in the capture container 1 when carrying the small animal trap itself. This prevents the shaft 4 and the like from being damaged. In addition, a bar-shaped regulating member 11 provided on the left and right wall surfaces is disposed on the upper part of the presser plate 7, and when the small animal trap itself is carried, the presser plate 7 is swayed in the capture container 1. This prevents excessive movement and damages the hinge fixing portion 8 and the like.

  Further, the seesaw plate 3 has a height at which the inlet side end portion 3a is equal to or higher than the height of the opening edge 2a of the inlet 2 and preferably exceeds a height when the small animal that has entered from the inlet moves to the back and tilts toward the back. Thus, the seesaw plate is configured to close the inlet 2.

  The small animal trap is provided with a lock mechanism 6 that holds and locks the inclined state of the seesaw plate 3 that is inclined downward toward the back.

  The locking mechanism 6 locks the seesaw plate 3 by locking the locking piece 12 provided on the seesaw plate 3 and moving up and down inside the capture container 1 and the locking piece 12 inside the capture container 1. The locking means 13 is configured to include.

  In this example, the locking pieces 12 are provided on both sides of the rear end portion of the seesaw plate 3 and are formed integrally with the seesaw plate 3 by bending a plate-like body. Both the locking pieces 12 are provided with first and second locking projections 12a and 12b on the inlet 2 side in the vertical direction. The first and second locking projections 12 a and 12 b are formed with a slanted edge on the upper side and a hook on which the lower side is locked by the locking means 13. The lower hook of the lower second locking projection is flush with the lower surface of the seesaw plate 3.

  The locking means 13 is provided over the left and right wall surfaces, and is used to guide the first and second locking projections 12a and 12b, and the left and right ends of the locking bar 14. A guide hole 15 is provided.

  The guide hole 15 is formed in a substantially V shape, the V-shaped first side 15a faces obliquely upward toward the inlet 2, is bent into the V-shape on the inlet 2 side, and the V-shaped second side 15b is It arrange | positions so that it may face diagonally downward toward the back side. The V-shaped first side 15a arranges the locking rod 14 when the lock mechanism is turned on. On the other hand, the V-shaped second side 15b arranges the locking rod 14 when the lock mechanism is turned off.

  Then, both end portions of the locking rod 14 are slidably inserted into the guide hole 15, and both end portions of the locking rod 14 are exposed to the outside of the capture container 1 to form a stopper portion. Yes. Both end portions of the locking rod 14 exposed to the outside of the capture container 1 are formed as release portions 16 that can release the locking of the locking pieces 12 from the outside of the capture container 1. That is, the locking means 13 has a release portion 16 that is exposed to the outside of the capture container 1 and can release the lock of the locking piece 12 from the outside of the capture container 1.

  3-6 is a figure explaining operation | movement of the small animal trap of this embodiment.

  FIG. 1 is an initial state of the operation in the present embodiment, and the inlet side end 3 a of the seesaw plate 3 is in an upwardly inclined state with respect to the floor surface of the capture container 1. The locking bar 14 is disposed on the V-shaped first side 15a, and the lock mechanism 6 is ON in this state.

  As shown in FIG. 3 and FIGS. 6A and 6B, in the initial state, when a small animal that has entered from the entrance 2 moves back on the seesaw plate 3 and enters the presser plate 7, The back end of the seesaw plate 3 is pressed from above by the weight of the small animal riding on the foot, the presser plate 7 rotates downward about the hinge fixing portion 8 and the seesaw plate 3 tilts toward the back. Rotate. Then, the locking piece 12 provided in the vicinity of the entrance side end 3a of the seesaw plate 3 rises. At this time, after the inclined surface on the upper side of the first locking projection 12a pushes up the locking bar 14 and slides it along the V-shaped first side 15a, the locking bar 14 again becomes the V-shaped first side 15a. It descends along and stabilizes at the position of the catch on the lower side of the first locking projection 12a (FIG. 3). In this state, even if it is going to lower the entrance 2 side of the seesaw plate 3, it becomes a first stage locked state.

  In the locked state of the first stage, as shown in FIG. 3, a predetermined gap is formed between the entrance side end 3 a of the seesaw plate 3 and the opening edge 2 a at the top of the entrance 2. . The gap is set to a size that does not pinch the tail of the invading small animal.

  Here, in the upper part of the inlet 2 of the capture container 1, a notch (not shown) that prevents the tail of a small animal that has entered the capture container 1 from the entrance 2 from being sandwiched between the seesaw plate 3 and the capture container 1. ) May be formed. This notch is preferably formed so that a plurality of slit-like notches extend upward from the opening edge 2 a of the inlet 2.

  Next, as shown in FIG. 4 and FIGS. 6B and 6C, the small animal that has further entered from the entrance 2 moves back on the presser plate 7, and the presser plate 7 rotates to turn the seesaw plate 3 back. If it rotates so that it may incline toward, the locking piece 12 will raise further. At this time, after the inclined surface on the upper side of the second locking projection 12b pushes up the locking bar 14 and slides it along the V-shaped first side 15a, the locking bar 14 again becomes the V-shaped first side 15a. It descends along and stabilizes at the position of the catch on the lower side of the second locking projection 12b (FIG. 4). In this state, a second-stage locked state that does not move even if the inlet 2 side of the seesaw plate 3 is lowered is obtained.

  In the second stage locked state, as shown in FIG. 4, the inlet side end 3 a of the seesaw plate 3 is at least equal to the height of the opening edge 2 a of the inlet 2 to close the inlet 2. It is configured.

  As described above, the lock mechanism 6 maintains the inclined state of the seesaw plate 3 in two stages, a first stage in which the seesaw plate 3 forms a gap with the inlet 2 and a second stage in which the inlet 2 is closed. Is configured to lock.

  When unlocking from the locked state of the first stage or the locked state of the second stage, both ends of the locking rod 14 exposed outside the left and right walls of the capture container 1 are gripped and moved to the V-shaped bent part. Then, the locking projections 12a, 12b and the locking bar 14 are unlocked, and in this state, the seesaw plate 3 is returned to the initial position.

  As shown in FIG. 5 and FIG. 6D, in the initial state, the locking bar 14 is moved from the V-shaped first side 15a toward the V-shaped second side 15b, so that the lock is free. State. That is, when the seesaw plate 3 is rotated and the locking piece 12 is raised, the locking bar 14 only hits the upper surface of the locking piece 12 and is not locked to the locking projections 12a and 12b and is not locked.

Thus, according to the small animal trap of this embodiment, since the lock mechanism 6 that holds and locks the inclined state of the seesaw plate 3 inclined toward the back is provided, the small animal enters from the entrance 2. When the seesaw plate 3 is tilted toward the back, the seesaw plate 3 is locked by the lock mechanism 6 when the seesaw plate 3 is tilted toward the back.
The locking mechanism 6 is provided on the seesaw plate 3 to move up and down inside the capture container 1 and to lock the seesaw plate 3 by locking the engagement piece 12 inside the capture container 1. And locking means 15 for locking. In this way, the locking piece 12 moves up and down inside the capture container 1 and the locking means 15 is locked inside the capture container 1 by the locking means 15. There is no risk of the lock mechanism 6 being destroyed by an external force caused by contact of a small animal from the outside.
Further, the locking means 13 has a release portion 16 that is exposed to the outside of the capture container 1 and can release the lock of the locking piece 12 from the outside of the capture container 1. The lock can be released from the outside of the capture container 1, and the usability for repeated use is very good.

  Further, the lock mechanism 6 locks the seesaw plate 3 while maintaining the inclined state of the seesaw plate 3 in two stages, a first stage in which the seesaw plate 3 forms a gap with the inlet 2 and a second stage in which the inlet 2 is closed. When the seesaw plate 3 is inclined toward the back when the small animal enters from the entrance 2 and moves to the back, the seesaw plate 3 is first placed between the entrance 2 and Locked in the first stage of creating a gap. At this time, the tail of the small animal is not pinched by the seesaw plate 3 by the gap, and the seesaw plate 3 is locked in this state, so that it cannot escape from the box. Next, since the seesaw plate 3 is locked in the second stage in which the entrance 2 is closed when the small animal advances further after being accommodated in the capture container 1 to the tail, the small animal that has entered is completely captured. Captured in 1.

  In addition, a presser plate 7 that inclines the seesaw plate 3 toward the back with a weight when an invading small animal rides is placed on the back end of the seesaw plate 3. When the end is hinged, the seesaw plate 3 is difficult to move until the small animal passes through the shaft 4 of the seesaw plate 3 and advances for a while, and the presser plate 7 moves up and down even when the seesaw plate 3 performs the seesaw motion. Is small. For this reason, it is less likely that small animals with strong vigilance are wary of a slight tilt of the scaffold. Since the seesaw plate 3 is tilted and locked when it moves to the back side until the small animal can no longer escape, the escape of the small animal is greatly reduced.

  In addition, a cutout is formed in the upper part of the inlet 2 of the capture container 1 to prevent the tail of a small animal that has entered the capture container 1 from the entrance 2 from being sandwiched between the seesaw plate 3 and the capture container 1. In this case, when the small animal invades from the entrance 2 and moves to the back, and the seesaw plate 3 is tilted toward the back and locked by the lock mechanism 6, the tail of the small animal is attached to the seesaw plate 3 by the notch. In addition, since the seesaw plate 3 is locked in this state, the seesaw plate 3 cannot be escaped from the box, and the small animal that has entered is completely captured in the capture container 1.

  FIG. 7 shows a second embodiment of the present invention.

  In this example, the capture container 1 is not a box shape but a cage shape. And the annular part 19 is formed in the both ends of the latching rod 14, and it is comprised so that the said annular part 19 can be inserted and slid by the guide member 18 bent and formed in the hook shape attached to the cage. .

  In this example, the inclined portion 18a on the back side of the guide member 18 is a lockable lock position, and the annular portion 19 of the locking rod 14 is positioned at this position, so that the first-stage and second-stage locks can be obtained. Is possible. Further, the bent portion 18b on the inlet side is a lock-free position, and the ring-shaped portion 19 of the locking rod 14 is positioned at this position, thereby becoming lock-free.

  Other than that is the same as that of the said 1st Embodiment, and there exists the same effect.
