Description

There is an application for the application of Article 30, Paragraph 2 of the Patent Law Published on the website of Japan's Cheapest Trap Shop on October 1, 2021

TECHNICAL FIELD The present invention relates to a vermin cage closing door structure capable of automatically closing the door upon detecting that a vermin has entered the cage.

For vermin cages that capture vermin such as wild boars, it is important to lure the target vermin into the cage and quickly close the cage door after confirming that the vermin has entered the cage. becomes. Therefore, a string for operating the closing door structure of the cage, such as a wire or a rope, is installed inside the cage, and when the vermin touches the string, an intrusion is detected and the door is closed at the same time as in Patent Document 1. An animal trapping device as described and a door closing device as described in US Pat.

The animal trap described in Patent Document 1 has an operating mechanism for closing the door on the upper part of the cage. The actuating mechanism is mainly a rectangular plate-shaped member having a notch recess cut at one end in the longitudinal direction and a stop hole drilled at the other end. A rotatably pivoted fulcrum shaft and a connecting rope whose one end is connected to the lower part of the cage door and whose other end is hooked to the notch recess of the turning member to lift the cage door upward and open the cage. and a tow rope fixed to the side of the cage with one end fixed in a stop hole in the pivoting member and the other end traversing the cage interior. With such a configuration, when a vermin that has entered the cage touches the traction rope, the turning member turns and the front linking rope that has been hooked on the notch recess is released. Since the front connecting rope that lifts the cage door is released, the cage door falls by its own weight and the door can be closed.

The door closing device described in Patent Document 2 mainly includes a pin member that can be protruded toward the outside of the cage (toward the cage door side) in a state where the tension spring is pulled, and a pin member that biases the tension spring in the pulling direction. A lever member that can release the biasing force by being rotated together, a weight that rotates the lever member by dropping outward from the rotation shaft of the lever member, and the weight before dropping is supported above. and a string having one end attached to the support plate and the other end stretched and fixed inside the cage. With this configuration, the tension spring is maintained in a tensioned state by the lever member, thereby causing the pin member to protrude outward from the cage. The open state of the cage can be maintained by placing the lifted cage door on top of the projecting pin member. As for the closing operation of the closing device, the vermin invades the cage and touches and pulls the thread stretched inside, causing the weight supported by the support plate to lose its support and fall. The dropped weight rotates the lever portion, and along with the rotation, the tension spring is released, and the initial tension causes the pin member to slide toward the inside of the cage. When the pin member slides toward the inside of the cage, the cage door placed on the upper part loses its support and falls downward, so that the door can be closed.

Animal trapping devices and door closing devices such as those described in Patent Document 1 and Patent Document 2 are capable of smoothly closing the cage door and reliably capturing vermin that has entered the cage. It is possible.
However, both inventions are configured to detect an intrusion and start a closing operation when a vermin touches a string such as a string or wire stretched in the cage. Therefore, there is a possibility that the closing operation is not performed because the vermin does not enter deep enough to avoid the string. In addition, since the closing operation is started by touching the wire, for example, even a child wild boar that is not to be captured or garbage blown by the wind touches the string body and the operation is started and the cage door is closed. There is also a risk of closing the door.

In addition, the animal trap described in Patent Document 1 lifts the cage door and maintains the open state by hooking a string on a notch concave portion of a rotatable rotating member.
However, in general, the cage door falls by its own weight and closes the cage. It is often something with Therefore, it is possible to keep the cage door balanced and lifted only when the pivot member is aligned with the string, which is very unbalanced given the weight of the cage door as described above. can be judged to be stable. Therefore, there is a risk that the revolving member will turn and the cage door will be closed due to an unexpected event other than the vermin coming into contact with the string, such as the impact of an object colliding with the vermin cage. In addition, as described above, since the cage door is generally a heavy object, there is a possibility that an eccentric load is generated in the cutout recess of the turning member that hooks the front linking rope, resulting in deformation.

Further, in the door closing device described in Patent Document 2, a lever member that biases a tension spring for projecting a pin member to the outside of a cage is rotated by dropping a weight to release the bias. By doing so, the cage door is closed.
However, if the vermin cage is used repeatedly, the lever member may be deformed due to deterioration over time or the weight of the weight, and the closing operation of the door may not be performed smoothly.

INDUSTRIAL APPLICABILITY According to the present invention, a cage door, which is a heavy object, can be maintained in a lifted state (an open state of the cage door) with a minimum force, and the inside of the cage of vermin can be detected based on information from a sensor provided in the cage. To provide a vermin cage closing door structure that detects an intrusion into a vermin cage and closes the vermin cage by a solenoid interlocking mechanism operated by an electric signal sent from a sensor.

In the vermin cage closing door structure according to the present invention, which has been made to solve the above problems, an infrared sensor is arranged in the vermin cage, and when the infrared radiation is blocked by the vermin and the power is turned on, the plunger part of the solenoid In the vermin cage closing door structure characterized in that the vermin door is closed through actuation, the solenoid interlocking mechanism for closing the vermin door is connected between the vermin door closing actuation part and the solenoid plunger part. A door closing interlocking mechanism interposed between them so as to close the vermin cage door by the electrical driving action of the plunger part of the solenoid, a string connected to the tip of the plunger part, and a hook connected to the tip of the string. A coupling ring, a fixing ring slidably engaged with the engagement ring and having a lower end fixed to the frame body of the vermin cage, and a tip end inserted into the hollow part of the engagement ring and a base end fitted to the annulus. a formed flip-up shaft, a shaft supporting a ring formed at the proximal end of the flip-up shaft, a flip-up lever in contact with the shaft proximal end of the flip-up shaft from below, and a proximal end of the flip-up lever and an actuating cord body whose end is connected to the cage door actuating connection and whose end is interlocked to the freely openable and closable cage door.

According to the vermin cage closing door structure according to the present invention, the infrared sensor detects that a vermin has entered the vermin cage, and the cage door is closed based on the electric signal of the infrared sensor. It is possible to reliably detect vermin that has entered the cage, and to prevent erroneous operations caused by animals not to be captured or obstacles carried by the wind.

In addition, by changing the detection range of the sensor depending on the installation position of the infrared sensor, it is possible to match the target of the cage door closing operation with the vermin to be captured.

In addition, the solenoid interlocking mechanism converts the force that causes the cage door to drop due to its own weight and tries to close the door into a rotating movement by means of a flip-up lever. Together, the cage door can be kept open, i.e., the cage door is lifted.

In addition, the solenoid interlocking mechanism distributes the weight of the cage door to each structure and maintains the open state with the minimum force, reducing the burden on each structure and allowing repeated use. Deformation and aged deterioration caused by this can be suppressed as much as possible.

[1. Concerning the structure of the closed door structure of the vermin cage]
An embodiment of a vermin cage closing door structure according to the present invention will be described below with reference to the accompanying drawings. The following embodiments are specific examples of the present invention, and do not limit the technical scope of the present invention.

1 and 2 show an open state and a closed state, respectively, of a vermin cage provided with a vermin cage closed door structure according to the present embodiment. Fig. 4 shows a right side view; FIGS. 3 and 4 show the vermin cage closing door structure according to the present embodiment before and after operation, respectively, and are right side views similar to FIGS. 1 and 2. FIG.

A vermin cage closing door structure M according to this embodiment is provided in a vermin cage VC, as shown in FIGS. The purpose of this provision is to detect the entry of vermin into the cage by the infrared sensor 100 provided on the side of the vermin cage VC and to close the cage door.

The vermin cage VC includes a box-shaped cage body C, an entrance E provided by opening any one of four facing surfaces of the cage body C, a cage door D closing the entrance E, and an entrance E. A cage door guide G provided along the opening of the cage door guide G, a support post B provided on the upper part of the cage body C and having a pulley P at the upper end, an operation string insertion part I provided on the upper part of the cage body C, consists of
The vermin cage VC captures the vermin V by closing the entrance E with the cage door D when the vermin V intrudes into the cage main body C from the entrance E. - 特許庁

The cage door D is lifted above the entrance E when the vermin cage VC is in the open state, and when the vermin V is captured, it falls by its own weight to close the entrance E. In addition, in order to prevent it from being lifted by the vermin V caught in the cage main body C when it is dropped and the entrance E is blocked, the weight is about 15 kg, for example.

The cage door guide G assists the cage door D to drop straight. Specifically, it is made of a U-shaped or L-shaped metal member. be provided.
The cage door guide G according to this embodiment shown in FIGS. 1 and 2 is illustrated with a length that extends from a position slightly higher than the upper part of the cage body C to a position higher than the ground, but in reality , The length is not particularly limited as long as the length is from a position higher than the cage main body C to the ground.

The support post B is integrated with the cage body C or fixed to the cage body C at the upper part of the cage body C near the entrance E. The support pillar B is for supporting the cage door D when the cage door D is opened (when the cage door D is lifted) or when the cage door D is closed. Therefore, the cage door D is roughly the same length.

In addition, a pulley P is provided at the upper end of the support post B, and an operation string 480 connected to the cage door D is passed through the pulley P to smoothly drop the cage door D when the door is closed. , that is, when lifting the cage door D, the cage door D can be easily lifted.
The support post B shown in FIGS. 1 and 2 is illustrated as a single post in the cage body C, but in order to increase the strength, a reinforcing member is diagonally inserted from the upper surface of the cage body C toward the support post B. It is also possible.

The actuating cord insertion portion I is for changing the angle of the actuating cord 480 extending from the pulley P in order to hook the actuating cord 480 to the cage door actuating connecting portion 473 of the vermin cage closing door structure M described later.
The operation string insertion part I is provided integrally or fixedly on the upper part of the cage body C, and has an inverted U shape. However, the actuating cord body insertion portion I may be of any shape as long as the actuating cord body 480 extending obliquely through the pulley P toward the cage body C can be inserted. It may be perforated. Further, as for the position of the operation string insertion portion I, it is preferable to position it in the vicinity of the vermin cage closed door structure M as shown in FIGS. However, the position of the actuating string insertion portion I is not limited to the position shown in the figure, and may be provided between the support column B and the vermin cage closing door structure M.

As shown in FIGS. 1 to 4, the vermin cage closing door structure M includes an infrared sensor 100 provided mainly on the side of the vermin cage VC, and a solenoid interlocking mechanism 400 that receives power from the infrared sensor 100 and closes the door. and consists of

The solenoid interlocking mechanism 400 includes a solenoid 410 electrically connected to the infrared sensor 100, a string 420 connected to the tip of a plunger portion 412 that constitutes the solenoid 410, and an engagement connected to the tip of the string 420. A ring 430, a fixing ring 440 that engages with the engagement ring 430 and has its proximal end fixed to the frame body c1 that is a component of the cage main body C, and a distal end that is inserted into the hollow portion of the engagement ring 430 to , a shaft 460 that pivotally supports the ring 451 formed at the proximal end of the flip-up shaft 450, and a flip-up shaft 450 that abuts the shaft proximal end of the flip-up shaft 450 from below. A lifting lever 470, a cage door operation connection part 473 formed at the base end of the flip-up lever 470, and an operation string body whose terminal end is connected to the cage door operation connection part 473 and whose tip end is interlocked with the freely openable and closable cage door D. 480 and more.

In addition, the said frame body c1 points out things, such as a metal wire material and a thin-plate material which form the cage main body C. As shown in FIG. As shown in FIGS. 3 and 4, the solenoid 410, the fixing ring 440, and a base portion 471 that supports a flip-up lever 470 and the like, which will be described later, are fixed to a thin plate-like substrate 300, and the substrate 300 is a frame. It is fixed to body c1. That is, the vermin cage closing door structure M is fixed to the upper frame body c1 of the vermin cage VC via the substrate 300. As shown in FIG.

The infrared sensor 100 is provided on the side of the vermin cage VC and electrically connected to the solenoid 410 via the electrical wiring 200 . The infrared sensor 100 can operate the solenoid 410 by blocking infrared irradiation and energizing the electrical wiring 200 when the vermin V passes in front of the infrared sensor 100 .

As for the installation position of the infrared sensor 100, by installing it at a position lower than the height of the vermin V to be captured, it is possible to reliably detect the intrusion into the cage body C. In addition, by providing a height slightly lower than the assumed height of the pest V to be captured, an object not to be captured, such as a young animal that is not to be captured, or an animal that is blown away by the wind etc. It is possible to reduce erroneous detection due to intruding dust or the like.

Moreover, the infrared sensor 100 can be used only during a period of time desired by the user, instead of always being in use. Therefore, the infrared sensor 100 has a changeover switch (not shown) so that the operation of the infrared sensor 100 can be switched between daytime only and nighttime only. In this way, by making it possible to switch the operation time of the infrared sensor 100, it is possible to suppress energy consumption during the time when vermin does not approach.
To determine whether it is daytime or nighttime, a timer type that uses a clock for a preset period of time or an optical sensor type that uses a light receiving sensor to determine whether it is daytime or nighttime is used.

It is also conceivable to use a reflective infrared sensor 100 to determine the size of an individual that has entered the cage main body C and determine whether to close the cage door D or not.
Specifically, the infrared sensor 100 is provided on the upper surface of the cage main body C and emits infrared rays downward. When the infrared rays are reflected by the invading vermin V, the distance from the upper surface of the cage body C to the back of the vermin V, that is, the height of the vermin V, is calculated from the time it takes for the reflection, and is based on a preset reference value. It is determined whether or not the cage door D is to be closed.

The solenoid 410 includes a coil 411 that forms a magnetic field in a certain direction when energized, a plunger portion that moves in and out of the winding of the coil 411 under the influence of the magnetic field, and a box 413 that houses the coil 411 and the plunger portion. and more.

The plunger part 412 is provided so as to move freely in and out of the coil 411 when not energized. ).

The box 413 has an opening in the front (the left side in FIGS. 3 and 4) through which the string 420 connected to the tip of the plunger 412 can be inserted.

The string 420 has one end connected to the tip of the plunger portion and the other end connected to the engagement ring 430 . The cord body 420 follows the sliding movement of the plunger portion 412 due to the actuation of the solenoid 410, and transmits stress to the engagement ring 430 connected to the distal end portion.
Further, the cord body 420 is interposed between the plunger portion and the engagement ring 430 to transmit the sliding movement of the plunger portion 412 to the engagement ring 430, and expands and contracts like an elastic material. Although the material to be used is not suitable, any material that meets these conditions may be used.

The engagement ring 430 is connected and engaged with the fixed ring 440 so as to be slidably connected. A cord 420 is connected to the engagement ring 430 , and follows the sliding operation of the plunger portion 412 via the cord 420 .

The fixed ring 440 includes a fixed portion 441 fixed to the substrate 300 and a relay ring 442 connected to the fixed portion 441 .

The fixing part 441 may be fixed to the substrate 300 and has an engaging hollow part for connecting the relay ring 442. For example, an eyebolt or the like as shown in FIGS. be done.

The relay ring 442 is connected and engaged between the engagement ring 430 and the fixing portion 441 , and is used for adjusting the height when the later-described flip-up shaft 450 is inserted into the engagement ring 430 . Therefore, a plurality of engagement rings 430 may be used as long as the height of the engagement ring 430 can be set to a predetermined height, or the fixing ring 440 alone may be omitted if the height of the engagement ring 430 can be set to a predetermined height.
However, the engaging ring 430 needs to be provided so that the hollow portion faces the front-rear direction (horizontal direction in the drawing) so that the flip-up shaft 450 can be inserted into the hollow portion.

Since the engagement ring 430 and the fixing ring 440 are slidably connected and engaged with each other, the plunger portion 412 slides in the sliding direction. It is pulled and tilts to the right side of the drawing.

The flip-up shaft 450 is made of a linear member and has an annular body 451 on the base end side.
A ring body 451 formed at the proximal end is pivotally supported by a shaft body 460 which will be described later.
The tip of the flip-up shaft 450 is inserted into the hollow portion of the engagement ring 430, and the inserted state is released when the engagement ring 430 is tilted rightward in the drawing due to the sliding of the plunger portion 412 described above. The Rukoto.

The shaft 460 is fixed to a base portion 471 that supports a flip-up lever 470 to be described later, and rotatably supports a ring 451 at the base end of the flip-up shaft 450 .

The flip-up lever 470 is a linear member rotatably supported by a rotation shaft 474 provided on a base portion 471 fixed to the substrate 300. In FIGS. It is composed of a bent abutment portion 472 and a cage door operation connecting portion 473 whose terminal end is bent upward.
As for the positional relationship between the rotating shaft 474 and the flip-up lever 470 , the rotating shaft 474 is positioned so as to abut on the bent portion forming the cage door operation connecting portion 473 . However, the pivot shaft 474 only needs to pivotally support the flip-up lever 470 , and may be directly provided at the bent portion forming the cage door operation connecting portion 473 .

One end of the actuating string 480 is connected to the upper part of the cage door D for opening and closing the entrance E of the vermin cage VC, and the other end is formed with a hook loop 481 for hooking the cage door actuating connecting portion 473 at the tip. there is
The actuation string 480 may be of any type as long as it can withstand the weight of the cage door D, such as a wire rope or a rope made of synthetic resin.

[2. How to use the vermin cage closing door structure]
Next, a method of using the vermin cage closing door structure according to the present embodiment will be described.
The vermin cage closed door structure M is a trap used to capture the vermin V. When the vermin V that has entered the vermin cage VC is detected by the infrared sensor 100 provided in the vermin cage VC, the electrical wiring 200 detects the vermin V. The cage door D can be closed by the connected solenoid interlocking mechanism 400 .

First, the preparation for installing the vermin cage VC as a trap, that is, the state before the cage door D is closed will be described.
The infrared sensor 100 is provided on the side surface of the cage body C and emits infrared rays. The electrical wiring 200 electrically connecting the infrared sensor 100 and the solenoid 410 is not energized when there is no obstacle blocking the infrared radiation of the infrared sensor 100 .

Since the solenoid 410 is in a non-energized state, the internal coil 411 does not generate a magnetic field and the plunger portion is slidable back and forth (horizontal direction in FIG. 3).
Therefore, the engagement ring 430 connected to the string 420 provided at the tip of the plunger portion 412 is in a state where no stress is generated in either direction.

The tip of the flip-up shaft 450 is inserted into the hollow portion of the engagement ring 430 .
The abutting portion 472 of the flip-up lever 470 is brought into contact with the vicinity of the annular body 451 formed at the proximal end of the flip-up shaft 450 from below.

The flip-up lever 470 is oriented so that the cage door operation connection part 473 faces upward by bringing the contact part 472 into contact with the lower part of the flip-up shaft 450 .

A hook loop 481 of an operating string 480 pulled to open the entrance E of the vermin cage VC is hooked on the cage door operating connecting portion 473 facing upward.
This actuating string 480 lifts the cage door D upward via a pulley P directed toward the upper end of the support post B of the vermin cage VC.
The hook annular portion 481 side hooked to the cage door operation connection portion 473 described above is hooked and connected to the cage door operation connection portion 473 after passing through the operation cord body insertion portion I.

That is, in the state before closing the door, the stress for lifting the cage door D can be efficiently distributed by each configuration of the solenoid interlocking mechanism 400 to maintain the open state (the state where the cage door D is lifted).

Specifically, the actuating cord 480 that lifts the cage door D passes through the actuating cord insertion portion I, thereby converting the stress that lifts the cage door D to the left in FIG.

The leftward stress is converted into a force to rotate the flip-up lever 470 counterclockwise in FIG. be.

The force that tends to rotate the flip-up lever 470 counterclockwise is regulated by bringing the contact portion 472 into contact with the flip-up shaft 450 .
At this time, the distance from the position where the actuation string 480 hooks and connects to the rotation shaft that supports the flip-up lever is compared with the distance from the rotation shaft 474 to the contact portion 472 that restricts rotation. The distance from the rotation shaft 474 to the contact portion 472, whose rotation is restricted, is longer than that of the rotation shaft 474, so that the force that restricts rotation can be weakened by the so-called lever principle.

The flip-up shaft 450 is brought into contact with the contact portion 472 downward in order to regulate the force with which the flip-up lever 470 tries to rotate. A force arises to
An engaging ring 430 inserted through the tip of the flip-up shaft 450 regulates the force that tends to flip the tip of the flip-up shaft 450 upward.

Also, as shown in FIG. 3, the abutting portion 472 is located near the shaft 460 that supports the flip-up shaft 450, and the distance from the abutting portion 472 to the tip of the engaging ring 430 is long. By doing so, it is possible to weaken the force that tries to flip up by the principle of lever as with the flip-up lever 470 .

The engaging ring 430 is fixed to the substrate 300 by the fixing ring 440, so that the force with which the flip-up shaft 450 is about to be flipped up can be regulated.

Due to the configuration and operation of the solenoid interlocking mechanism 400 described above, it is possible to efficiently maintain the state in which the heavy cage door D is lifted, that is, the vermin cage VC is opened, with minimal force.

Next, the door closing operation will be described.
In the vermin cage closed door structure M, the infrared irradiation of the infrared sensor 100 provided on the side of the cage body C is blocked by the vermin V that has entered the cage body C, so that the solenoid 410 is energized and the solenoid is interlocked. Mechanism 400 begins to operate.

A magnetic field is generated in the coil 411 inside the solenoid 410 energized with the infrared radiation blocked, and a force is generated to draw the plunger portion 412 into the winding of the coil 411 (to the right in FIG. 4). By doing so, as shown in FIG. 4, the plunger portion 412 slides rightward.

The string 420 connected to the tip of the plunger portion 412 is partially pulled into the solenoid 410 as the plunger portion 412 slides and is pulled to the right.

The engagement ring 430 connects the other end of the string 420 connected to the plunger portion 412 , so that the plunger portion 412 slides through the string 420 . It tilts to the right around the ring 440 (sliding to the right with respect to the flip-up shaft 450).

By tilting the engagement ring 430 to the right, the flip-up shaft 450 inserted into and engaged with the hollow portion of the engagement ring 430 is released from the inserted state.
In other words, canceling the inserted state means that there is no way to regulate the above-described force that causes the flip-up shaft 450 to flip upward.

In addition, the flip-up shaft 450 is subject to a force that causes it to be flipped upward. By sliding in a completely different direction (to the right in FIGS. 3 and 4), the restraint can be released with a small force.

Since the force with which the flip-up shaft 450 is about to be flipped up is no longer restricted, the force with which the flip-up lever 470 is rotated cannot be regulated.
That is, the force of the actuating string 480 hooked and connected to the cage door actuating connecting portion 473 to resist the force of lifting the cage door D is lost.
As a result, the flip-up lever 470 rotates counterclockwise as shown in FIG.

The cage door operation connection part 473, which faced upward before the operation, falls to the left side by rotating, and the hooked state of the operation string 480 is released, and the cage door D falls downward due to its own weight. Become.
By dropping the cage door D, the entrance E of the vermin cage VC is closed as shown in FIG.

As described above, the vermin cage closing door structure M according to the present invention can detect the vermin V that has entered the vermin cage VC by the infrared sensor 100, and can quickly close the vermin cage door D. The vermin V can be captured with certainty.

Further, in order to open the vermin cage VC, the heavy cage door D must be raised. The weight of the solenoid interlocking mechanism 400 can be dispersed by each configuration to efficiently maintain the door open state.

In addition, as a method of releasing the restriction for closing the door, the direction of the force that restricts the engagement ring 430 (upward force applied to the flip-up shaft 450) is different from the direction (rightward with respect to the flip-up shaft 450). By adopting the method of sliding, it is possible to minimize the force involved in releasing the restraint. Therefore, a simple mechanism such as the solenoid 410 can be used as the mechanism for sliding the engagement ring 430 .

In the vermin cage closing door structure M described above, the sliding motion of the engaging ring 430, which is the starting point of the door closing operation, is affected by the coil 411 that generates a magnetic field when energized, and the magnetic field generated by the coil 411. Although this is done by the moving plunger portion and the string connected to the plunger portion 412, any mechanism can be used as long as the regulation of the flip-up shaft 450 can be released by sliding the engagement ring 430. It may be a configuration.
For example, in response to an operation instruction transmitted by the infrared sensor 100 provided in the vermin cage VC, the connecting portion connected to the engaging ring 430 is slid using a method such as a rack and pinion method. good too.

The above description of the embodiment is an example of the present invention, and the vermin cage closing door structure M according to the present invention is not limited to the above-described embodiment. Therefore, it goes without saying that various modifications other than the above-described embodiments are possible according to the design and the like, as long as they do not deviate from the technical idea of the present invention.
