Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an animal trap for catching stray dogs, stray cats, etc.

(Prior Art) In a conventional trap of this type, for example, bait for decoy is attached to one end of the arm rod, and a hanging member is provided to the other end to hang the trap door of the trap box in an open state. When a wild dog or the like bites into the bait and pulls it, the arm rod operates to remove the hanging member from the trapping door, which closes the trapping door under its own weight. be.

(Problems to be solved by the invention) However, in the past, there were cases in which the trapping door did not close when only the bait was taken, resulting in low reliability.

In addition, although it is common practice to scatter lure bait around the bait, there are cases where the trap only eats the lure bait and does not eat the decoy bait, and the trap does not work. Ta.

(Means for solving the problem) A trapping door that can be opened and closed in the vertical direction and closed by its own weight is provided in the opening for animal entry provided on one side of the trapping box, and the trapping door is opened. A suspension member is provided to suspend the device in a suspended state, and the suspension member is made of a material that melts when an overcurrent flows,
An electric circuit closing means for causing an overcurrent to flow through the hanging member is provided within the trap box.

(Function) When an animal that has entered the capture box activates the closing means due to its weight or contact pressure, an electric circuit is closed that causes an overcurrent to flow through the hanging member. As a result, an overcurrent flows through the electric circuit, fusing the hanging member, and the trapping door, which is released from the hanging state, descends under its own weight and closes the opening of the trapping box.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

An animal trap according to the present invention is shown in FIG. 1 is an animal trap, 2 is a trap box, and 3 is a trap door.

The capture box 2 is a rectangular box made of wire mesh, and the interior thereof is divided into a capture chamber 2a and a decoy chamber 2b by a partition wall 5 made of wire mesh. The trapping chamber 2a is a chamber for trapping stray dogs, stray cats, etc., and an opening 6 for animal entry is provided at the front end of the trapping chamber 2a, and the trapping door 3 is supported in the opening 6 so as to be openable and closable. A door support frame 7 is provided.

The door support frame 7 is formed by framing upper and lower frame plates 7a, 7b and left and right frame members 7c, 7d in a rectangular shape,
Its height H is about twice the height h of the opening 6, and a guide plate 8 is stretched over the rear surface of the portion that projects upward from the opening 6. The above left and right frame materials 7c,
Reference numeral 7d is made of channel steel having a U-shaped inward cross section, and the groove portions 9, 9 act as opening/closing grooves for the capture door 3. Further, an upper suspension hook 10 is provided at the center of the lower surface of the upper frame plate 7a.

The capture door 3 has a wire mesh 12 stretched over a frame plate 11, and the left and right sides 3a, 3b are slidably fitted into the opening/closing grooves 9, 9 of the door support frame 7, respectively, so that it can be opened and closed in the vertical direction. It is considered possible. A lower lifting hook 13 is provided at the center of the upper end of the capture door 3 in correspondence with the upper lifting hook 10 of the door support frame 7.

The decoy chamber 2b is a chamber for storing live decoys such as rabbits and chicks, and the rear end of the decoy chamber 2b can be opened and closed by an opening/closing door 14.

The dimensions of the capture box 2 are set according to the animal to be captured; for example, for a dog or cat, the height h is 40 cm, the width w is 40 cm, and the length l is 115 cm.
It is considered to be a degree.

The door closing means is electrically actuated, and includes the hanging member 15, the electric circuit 16 (see Fig. 3), the operating switch 17 constituting the closing means for closing this circuit and supplying current, and when the device is not in use. It consists of a main switch 31 that opens the circuit. Hanging member 15
is for suspending the capture door 3 in the open state, and as shown in FIG.
0 and 13, respectively, to connect these, and on the other hand, to the electric circuit 16 described above.
The suspension member 15 is made of a conductive material that can be easily fused with a relatively small current, and for example, a commercially available thread fuse or the like is used.

The electric circuit 16 is connected to the power source 1 as shown in FIG.
8. The operating switch 17 and the suspension member 15 are connected in series, and as the power source 18, for example, a storage battery is used. When the operating switch 17 is closed and the electric circuit 16 is closed, the suspension member 15 is fused. The structure is such that a sufficient current (overcurrent) flows through it.

The actuation switch 17 is provided inside the trapping chamber 2a of the trapping box 2, and is activated by the weight or contact pressure of the animal that has entered the trapping chamber 2a, and its structure is shown in FIGS. 4 and 5. The operating switch 17 consists of a base plate 20 fixed to the floor 19 of the capture chamber 2a and a movable footplate 21.
1 has a support shaft 22 made of a rod with a circular cross section fixedly installed at the center of the lower surface 21a, and this is supported in a balanced manner by the center of the upper surface 20a of the substrate 20 by bearings 23, 23 made of cylindrical bodies. ing.
The inner diameters of the bearings 23, 23 are formed to be slightly larger than the support shaft 22. As a result, when a force is applied to the movable footboard 20, it can swing up and down about the support shaft 22. Ten-side contacts 24, 24 and one-side contacts 25, 25 are provided at the center of both front and rear ends of the upper surface 20a of the base plate 20 and the lower surface 21a of the movable footboard 21, respectively, so as to face each other. When the switch is swung back and forth and tilted, both contacts 24 and 25 come into contact and the operating switch 17 is closed. Note that when the movable footboard 21 is in an equilibrium state, that is, in an open state, the bolt 3
Balance weights 34, 3 screwed to 3, 33
4 or a spring (not shown) to keep it stable under normal conditions, and this adjustment is made in the capture chamber 2a.
This is done through a small door 26a provided on the right side 26 of the.

In FIG. 1, reference numeral 27 is a trap box for transferring animals captured in the trap chamber 2a to another location, and is made of wire mesh like the trap box 2, and has an opening 27a at the front end. This is provided with an opening/closing door 28 that can be opened and closed up and down, and a means 30 for connecting to the trap box. Furthermore, a handle 29 for carrying is provided on the top. The opening 27a has a size corresponding to the opening 6 of the capture chamber 2a.

Next, how to handle the animal trap 1 will be explained.

An animal trap 1 is installed in a place where an animal to be captured, such as a stray dog, is likely to be present. Then, living things such as chicks are housed as decoys in the decoy chamber 2b of the trap box 2 to attract stray dogs. on the other hand,
After opening the operating switch 17, the capture chamber 2
The capture door 3 of a is lifted upward, the upper and lower suspension hooks 10 and 13 are connected by the suspension member 15, and suspended in the open state.

Incidentally, instead of the living creature, bones or the like may be placed between the operating switch 17 and the partition wall 5 in the capture chamber 2a.

A wild dog finds a living thing in the decoy room 2b, and tries to attack it by entering the trapping room 2a through the opening 6 and approaching the partition wall 5. At this time, the stray dog
trample on. Then, the movable footplate 21 is tilted either forward or backward by this pedal force, whereby the contacts 24 and 25 come into contact, the actuation switch 17 is closed, and the electric circuit 16 is closed. Then, an overcurrent flows through the electric circuit 16, the hanging member 15 melts, and the trapping door 3 descends under its own weight to close the opening 6, trapping the stray dog inside the trapping chamber 2a.

The stray dogs captured in the trapping room 2a are transferred to a trapping box 27 and then transported to a health center or the like. In this transfer operation, first, connect the opening 27a of the trap box 27 to the opening 6 of the trap chamber 2a using the connecting means 30, open the opening/closing door 28 and the trap door 3 at the same time, and then remove the stray dog. Drive it into the capture box 27 and close the opening/closing door 28.

In addition, in the above-mentioned embodiment, the closing means for closing the circuit may be provided on the bottom surface as shown in the figure.
The side wall surface may be made narrow enough to allow contact with the animal, and closing means may be provided on this side wall surface.

(Effects of the invention) As detailed above, according to the invention, the decoy bait does not use the actuating medium and is operated electrically by the contact pressure of the animal, so there is no malfunction and it is reliable. Highly sexual.

In addition, the power supply is only activated when the fuse is blown, and the power consumption is low, making it economical.
