Description

The present invention relates to a transmitter for traps.

Patent Literature 1 discloses a transmission device that, when a prey is caught in a trap, pulls a pull string attached to the trap, pulls out a pin, and transmits a pulse signal.

Patent Literature 2 discloses a technique in which, when prey is caught in a tying trap, an acceleration sensor provided in the tying trap detects the capture of the prey and transmits capture information to the outside.

Japanese Utility Model Laid-Open No. 1-8124 Japanese Patent No. 6725445

In the transmission device disclosed in Patent Document 1, when the prey after being caught is quiet, the load transmitted from the trap to the pull string may be less than the pull-out load of the pin. In this case, since the pin is not pulled out from the transmitter, no pulse signal is transmitted. In other words, when the captured prey is quiet, the capture of the prey cannot be detected, so the reliability of the capture detection is low.

In the technique disclosed in Patent Document 2, if the prey goes wild after being caught, there is a risk that the acceleration sensor arranged above the tying trap will fall to the ground and be damaged.

The elastic claws 34 are hooked to the through holes 29 of the support portion 25 . Specifically, the claw portion 34B is hooked to the edge portion of the through hole 29 of the support portion 25 .

In the following description, the position of the operating member 30 when the elastic claw 34 is caught in the through hole 29 with the operating member 30 attached to the mounting member 22 is referred to as the non-operating position (see FIGS. 7 to 9). called. Here, when the operating member 30 is in the non-operating position, it is grasped as an uncaptured state in which the trap device 60 does not capture the birds and animals. Furthermore, in the present embodiment, when the operating member 30 is at the non-operating position, it is possible to temporarily hold the position of the operating member 30 by the magnetic forces of the magnetic members 28 and 36 .
On the other hand, with the operating member 30 attached to the mounting member 22, the elastic claw 34 is disengaged from the through hole 29 and the screw member 38 is in contact with the lower end of the elongated hole 26. Position (see FIGS. 10-12). Here, when the operating member 30 is at the operating position, it is understood that the trap device 60 is in a trapping state in which a bird or animal is captured.

As shown in FIGS. 13 and 14, the pair of holding portions 35 are provided at both ends of the connecting portion 33, respectively. The holding portion 35 is plate-shaped, and has a through hole 35A formed in the central portion thereof. A connection member 50 is inserted into each through hole 35A of the pair of holding portions 35 . As shown in FIGS. 2 and 3, when the attachment member 22 is attached to the attachment target T, the connection member 50 receives a predetermined tensile load from the wire 61 extending from the trap device 60. is held by the holding portion 35 of the

-Magnetic member 36-
The magnetic member 36 is a permanent magnet and is provided on the motion member 30 as shown in FIGS. Specifically, as shown in FIGS. 7 and 10, the magnetic member 36 is embedded in the motion member 30 on the side opposite to the holding portion 35 (on the upper side in FIGS. 7 and 10).

Further, the operating member 30 is made of a resin material. As this resin material, it is preferable to use a resin material having excellent weather resistance. In addition, the present invention is not limited to the above configuration. The motion member 30 may be made of metal material or wood.

(Detection sensor 40)
The detection sensor 40 is a sensor that detects the motion of the motion member 30 . Specifically, the detection sensor 40 detects a magnetic force change due to movement of the magnetic member 36 . More specifically, the detection sensor 40 detects changes in magnetic force caused by movement of the magnetic member 36 that moves together with the operation member 30 . The detection sensor 40 is housed in the housing portion 24 of the mounting member 22, as shown in FIGS. The housing portion 24 also houses a transmitting device 42 . A portion of the mounting member 22 that forms the accommodation portion 24 is made of a material that allows the detection sensor 40 to detect the magnetic force from the magnetic member 36 and allows the transmission device 42 to transmit radio waves to the outside.

(Transmitting device 42)
The transmission device 42 is a device for transmitting detection information detected by the detection sensor 40 to the outside. The transmission device 42 can wirelessly transmit the detection information to the outside.

- power generator 44 -
In addition, the transmitting device 20 further includes a power generating device 44 (see FIG. 18) for operating the transmitting device 42 . The power generator 44 is accommodated inside the mounting member 22 together with the detection sensor 40 and the transmitter 42 (see FIGS. 8 and 9). Further, the power generator 44 of the present embodiment is a power generator using electromagnetic induction, and generates power by changes in magnetic force (changes in magnetic flux density) due to movement of the magnetic member 36 .
Although the power generator 44 of this embodiment uses electromagnetic induction, the present invention is not limited to this. For example, a solar power generation device or a storage battery may be used as the power generation device 44 .

(Connecting member 50)
As shown in FIGS. 1 and 3 , the connection member 50 is a member that connects the mounting member 22 and the trap device 60 . Specifically, the connection member 50 is held by the pair of holding portions 35 of the operation member 30 with the wire 61 extending from the trap device 60 hooked. Also, the connection member 50 is designed to disconnect the attachment member 22 and the trap device 60 when a tensile load higher than a predetermined value is received from the wire 61 of the trap device 60 . Specifically, when a tensile load higher than a predetermined value acts on the connecting member 50, the connecting member 50 is destroyed and the connection between the attachment member 22 and the trap device 60 is released.
Here, when the operating member 30 is in the non-operating position, the wire 61 is under tension. When a bird or animal is caught by the trap device 60 , a tensile load acts on the connecting member 50 via the wire 61 . When a tensile load acts on the connecting member 50, the elastic claw 34 is disengaged from the through hole 29 and the operating member 30 moves along the longitudinal direction of the elongated hole 26 (downward in FIG. 5). Then, when the screw member 38 comes into contact with the lower end of the elongated hole 26, the operating member 30 stops. When the motion member 30 stops, the tensile load from the wire 61 concentrates on the connecting member 50 . In this state, if the tensile load from the wire 61 becomes higher than a predetermined value (preset value), the connection member 50 will break.

Since the connection member 50 is held by the pair of holding portions 35 , the trap device 60 and the mounting member 22 are connected via the action member 30 . The connection member 50 is a rod-shaped member, for example, a cylindrical rod-shaped member.

Moreover, it is preferable to set the material and cross-sectional area of the connecting member 50 so that the connecting member 50 is surely destroyed when the tensile load received from the wire 61 reaches a predetermined value. Further, for example, like a connection member 51 of a modified example shown in FIG. 15, a notch may be formed as a fragile portion 51A in the central portion in the longitudinal direction. On the other hand, like a connecting member 52 of a modified example shown in FIG. 16, an annular groove continuing in the circumferential direction may be formed as a weakened portion 52A in the central portion in the longitudinal direction. A tensile load from the wire 61 is concentrated on these fragile portions 51A and 52A.

In addition, the connection member 50 of this embodiment is an example of the connection part in this invention.

Next, the operation of this embodiment will be described.
In the transmitting device 20 of the present embodiment, when the operating member 30 receives a tensile load from the trap device 60 in the bird-catching state, the operating member 30 operates as shown in FIG. . Detection information detected by the detection sensor 40 is transmitted to the outside via the transmission device 42 . As described above, in the transmission device 20, when a bird or animal is captured by the trap device 60, the capture of the bird or animal is detected by the operation of the operation member 30, so the reliability of the capture detection is high.

Further, in the transmission device 20, when the connection member 50 receives a load higher than the tensile load in the bird and animal trapping state from the trap device 60, the connection member 50 is pulled from the mounting member 22 and the trap device 60 as shown in FIGS. disconnect the Therefore, it is possible to suppress the application of a load equal to or greater than the predetermined load to the attachment member 22 attached to the attachment target T. In this way, in the transmission device 20, when the trap device 60 catches a bird or animal, damage to the mounting member 22 and the electronic device (here, the sensor unit 46) around the mounting member 22 can be suppressed. That is, it is possible to suppress damage to the transmission device 20 when the bird or animal is captured by the trap device 60 .

In the transmission device 20, when the motion member 30 receives a tensile load from the trap device 60 in the bird and animal trapping state, the motion member 30 moves relative to the mounting member 22 as shown in FIG. As the motion member 30 moves, the magnetic member 36 also moves. Due to this movement, the relative position of the magnetic member 36 with respect to the detection sensor 40 changes, and the magnetic force of the magnetic member 36 detected by the detection sensor 40 changes. Then, when the detection sensor 40 detects a change in the magnetic force of the magnetic member 36 , the detection information is transmitted to the outside by the transmission device 42 . As described above, in the transmission device 20, the detection sensor 40 detects a change in the magnetic force accompanying a change in the relative position of the magnetic member 36 with respect to the detection sensor 40, so that the capture of the bird or animal in the trap device 60 can be grasped with high accuracy. be able to.

In the transmission device 20, the connection member 50 connects the trap device 60 (specifically, the wire 61 of the trap device 60) and the mounting member 22 via the operation member 30, so that the trap device 60 can capture birds and animals. After detection, the attachment member 22 and the trap device 60 can be reliably disconnected.

Further, in the transmitting device 20 , since the operating member 30 has the holding portion 35 , the connecting member 50 can be easily held by the operating member 30 .

Since the transmitting device 20 further includes the power generation device 44 for operating the transmitting device 42, malfunction of the detection sensor 40 and the transmitting device 42 due to power shortage can be suppressed.

Further, in the transmission device 20, the detection sensor 40 and the transmission device 42 are housed in the housing portion 24 of the mounting member 22. Therefore, for example, the detection sensor 40 and the transmission device 42 are housed in a member different from the mounting member 22. The size of the device can be reduced compared to the one that does.

Furthermore, in the transmission device 20, since the power generation device 44 is housed in the housing portion 24 of the mounting member 22, for example, compared to a device in which the power generation device 44 is housed in a member different from the mounting member 22, the device can be It can be made smaller.

In addition, in the transmission device 20 , the rod-shaped connecting member 50 may be provided with a fragile portion. For example, when the connection member 51 is provided with the fragile portion 51A, when the connection member 51 receives a load higher than the tensile load from the trap device 60 in the bird and animal trapping state, the connection member 51 is destroyed starting from the fragile portion 51A. The connection between the attachment member 22 and the trap device 60 is released. By thus providing the connecting member 51 with the fragile portion 51A serving as the starting point of destruction, the load leading to disconnection between the mounting member 22 and the trap device 60 can be easily controlled. In other words, when a load exceeding a predetermined tensile load acts on the connecting member 51, the connection between the mounting member 22 and the trap device 60 can be reliably released. For example, even when the fragile portion 52A is provided like the connecting member 52, the same is true for the connecting member 51. In other words, by providing the connection member 52 with the fragile portion 52A that serves as the starting point of destruction, the load leading to disconnection between the attachment member 22 and the trap device 60 can be easily controlled. In other words, when a load exceeding a predetermined tensile load acts on the connecting member 52, the connection between the mounting member 22 and the trap device 60 can be reliably released.

Also, the transmission device 20 can be connected to an existing trap device. For example, a wire is connected in the middle of the tying trap, this wire is hooked on the connection member 50, and the connection member 50 is attached to the attachment member 22 attached to the attachment target T by the pair of holding portions 35 of the operation member 30. By holding it, it is possible to obtain the same action and effect as the transmission device 20 described above.

Since the transmission device 20 transmits to the outside that the birds and animals have been captured by the trap device 60, the birds and animals can be protected before they weaken. By connecting such a transmitting device 20 to the trap device 60, it becomes possible to maintain the ecosystem of the place where the trap device 60 is installed.

Further, in the transmission device 20 of the present embodiment, even if the connection member 50 is destroyed by capturing the birds and animals with the trap device 60, the pair of holding portions 35 of the operation member 30 can hold rod-shaped members (for example, twigs, disposable chopsticks, etc.). consumables), the transmitting device 20 can be reused. Since it can be reused in this way, the operation cost of the transmitting device 20 can be suppressed. Note that FIG. 17 shows a state in which a twig 65 is used instead of the connection member 50 to utilize the transmitting device 20 .

In the above-described embodiment, the connection member 50 is a rod-shaped member, but the present invention is not limited to this configuration. There is no particular limitation as long as the wire 61 and the motion member 30 can be connected and the connection between the motion member 30 and the wire 61 can be released with a predetermined tensile load.

In the above-described embodiment, the detection sensor 40, the transmitter 42 and the power generator 44 are unitized, but the present invention is not limited to this configuration. For example, the detection sensor 40, the transmission device 42 and the power generation device 44 may not be unitized, only the detection sensor 40 and the transmission device 42 may be unitized, or only the transmission device 42 and the power generation device 44 may be unitized. good too.

In the above-described embodiment, the trap device 60 is a tying trap, but the present invention is not limited to this configuration. For example, the trap device may be a box trap or other trap. Box traps include a large-sized trap device 62 shown in FIG. 19 and a medium-sized trap device 64 shown in FIG. The trap device 62 can capture large birds and animals (for example, deer and wild boar), and the trap device 64 can capture medium-sized animals (for example, foxes). Also, in the trap device 62, the entrance of the box trap is opened and closed by a slide door. When the sliding door is closed, a wire (not shown) is pulled to activate the transmission device 20 . That is, the detection information is transmitted from the transmission device 20 . On the other hand, in the trap device 64, the entrance of the box trap is opened and closed by a revolving door. When this revolving door is closed, a wire (not shown) is pulled to activate the transmission device 20 . That is, the detection information is transmitted from the transmission device 20 .

In the above-described embodiment, the support portion 25 that is the lower portion of the mounting member 22 is fixed to the housing portion 24 that is the upper portion, but the present invention is not limited to this configuration. For example, the supporting portion may be a separate member from the mounting member having the accommodating portion, and the supporting member, which is the separate member, may be rotatably mounted to the mounting member. In this case, since the operating member can rotate with respect to the mounting member together with the supporting member, the degree of freedom in setting the trap is improved.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above, and can be implemented in various modifications other than the above without departing from the spirit of the present invention. is of course.
