Description

[Detailed Description of the Invention] The present invention aims to provide a box dropper for catching brown bears having a novel configuration.

The details of one embodiment of the present invention will be described below with reference to the drawings.

1 is a box drop for catching brown bears.

The structure is such that an opening 2A is formed on one side of a horizontally long cage body 2 that can be freely added to.
A feeding box 3 is installed inside the other side of the cage 2.
A footboard 4 is disposed in a position close to the feeding box 3 on the bottom surface 2B of the feed box 3 so as to be freely raised and lowered, and a drop lid 5 is provided in the opening 2A that can be raised and lowered to block the opening 2A by lowering the footboard 4. ing.

Therefore, the cage body 2 is constructed by installing vertical bars 2D at predetermined intervals in a frame 2C made of angle materials, etc., and has a horizontally long cylindrical shape consisting of a bottom surface 2B, left and right side surfaces 2E, and a ceiling surface 2F. ing.

Further, a rail 6 having a U-shaped cross section is planted on the left and right edges of the opening 2A, and a drop lid 5 is attached within the rail 6 so as to be able to rise and fall.

Therefore, stoppers 7 are provided on the left and right portions of the upper end surface of the lid 5.

This stopper 7 is a round tube 7 fixed to the top surface of the lid 5.
A stopper unit 7C having a front-end shape is slidably fitted into A and 7B, and a spring 7E is stretched between the vertical rod portion 7D of the stopper unit and the round tube 7A.

As a result, the stopper unit 7C is always pressed in the direction of the rail.

Therefore, to explain the operation of this stopper 7, when the lid 5 is raised so as to be positioned above the rail, the stopper unit 7C is pressed toward the rail by the spring 7E, and as a result, the tip of the stopper unit 7C is is in contact with the inner wall of the rail.

Furthermore, when the lid 5 is dropped below the rail, that is, when the lid 5 blocks the opening 2A, the tip of the stopper unit 7C is inserted into the lock hole 6A formed in the rail by the spring 7E. As a result of the penetration, the lid 5 is locked.

Reference numeral 8 denotes a link connected between the left and right stoppers 7, and a wire 8A of a predetermined length is suspended from the center of the link.

Therefore, when the wire 8A is strongly pulled downward, each stopper assembly 7C is pulled inward, and the locked state changes to the open state.

This is so that if the lid 5 falls while a person is inside the box drop 1 by mistake, the person inside can grab the wire 8A and escape by themselves.

The footboard 4 has a shaft 4A protruding from its lower edge inserted into a pipe 4B attached to the bottom of the cage body 2, and is attached to the footboard 4 so as to be able to rise and fall freely.
The lower end of wire 4C hanging down from F is connected.

Therefore, a rotatable shaft 9 is suspended horizontally on the upper surface of the ceiling surface 2F, and a first projecting piece 9A connected to the upper end of the wire 4C is fixed to this shaft 9. The first protruding piece 9A is connected to the second protruding piece 9B at a predetermined angle.
A pull wire 9C for operating the lid 5 is connected to the second projecting piece 9B, and the wire 9C is extended in the direction of the lid 5. Furthermore, a rod-shaped wire is attached to the tip of the wire 9C. A stopper 9D is connected, and this stopper 9D is configured to move forward and backward in the upper surface portion of the ceiling surface 2F in the direction of the lid 5, and a small hole 5A in the lower edge of the lid 5 into which the stopper 9D is inserted and removed. is drilled.

9G' is a cross-sectional cover that covers the upper surface of the wire 9C.

2D' is a connecting plate that connects and reinforces the vertical bars 2D in a parallel state, and 2G is a protrusion that connects the cage body 2 that is divided in the front and back.
This projecting piece has a planar shape, is provided in a protruding manner opposite to the connecting portion of the cage body 2, and is connected with a connecting bolt 2G'.

2H is a side plate, which is fixed with screws 2H' around the location where the feeding box 3 is installed in the cage body.

This is to prevent bears from doing mischief from outside.

Reference numeral 2 is a support rod, and hooks 2I'' and 2'''', which engage and disengage from the connecting plate 2G, are protruded from one side of a rod 2I' having a predetermined size.

This is when transporting the box containing the bear to the desired location.
The support rods 2 are connected to each of the left and right front parts and the left and right rear parts of the box drop, and are used by supporting them like so-called tanks.

2J is a handle-shaped feeding box, and if it is installed parallel to the longitudinal direction of the cage body on the bottom surface 2B of the cage body, bears will be attracted to this feeding box 2.
Since I was not guided by J, I ended up going deep inside the box.

Since the proposed device is constructed as described above, when a bear enters the box and steps on the footboard 4 in an attempt to approach the feeding box 3, the wire 4C, the first protrusion 9A, the second protrusion 9B1, the wire 9C, and the stopper 9D is interlocked, and the lid 5 supported at the upper position by the stopper 9D falls, blocking the opening 2A and trapping the bear.

After this, the bear will be shot to death or other measures will be taken to study the bear's ecology.

In this case, the fallen lid 5 is safe because the stopper unit 7C is automatically inserted into the lock hole 6A and locked.

If a person accidentally enters inside and locks the lid 5, he or she can escape by operating the wire 8A as described above.

In addition, because a side board was placed around the place where the bait box 3 was installed in the cage, the bear could not play with it from the outside, and the bait box 1 was set up in the mountains for many days in order to catch it. During this period, the box drop 1 can be maintained in a normal state.

According to this proposal, it can be said to be a useful device that can safely and reliably catch a bear.
