Description

[Detailed description of the invention] [Field of industrial application] This invention is a long thin strip that can be wrapped around trees to prevent damage by wild animals, and can be bent to have a V-shaped cross section. This invention relates to a bending tool for a prevention band.

[Conventional technology]

As a conventional method for drawing and bending plate materials, JP-A-56
-66322 is publicly known. This is a pair of drawing dies consisting of a moving die and a fixed die which are divided into upper and lower parts, one of which is movable relative to the other, and each of which is provided with a V-shaped protrusion and a V-shaped groove. The method involves bending the plate material at a predetermined angle by pinching the plate material with a die.

[The problem that the idea aims to solve]

In the prior art, since the device itself is relatively large, it is not portable enough to be carried around and used to bend the corrosion prevention strip at the site.

Therefore, an object of the present invention is to provide a bending tool for a belt plate for preventing food damage, which is highly portable and can be folded reliably.

[Means to solve the problem]

This device consists of a receiver for a strip plate for preventing feeding damage and a lid rotatably connected to the receiver, and the receiver is provided with a groove whose included angle gradually increases from one side to the other. The receiver is provided with a protrusion whose included angle gradually increases from one side to the other, and the included angle between the groove and the other end of the protrusion is 180°, and the receiver and the lid are connected to each other so as to be openable and closable.

[Effect]

After placing the feeding damage prevention strip in the groove of the receiver with the end protruding to one side, align the lid so that the protrusion fits into the groove and pull out the end, the included angle will gradually move from one side to the other. Sandwiched between the growing grooves and protrusions, the corrosion prevention strip is formed into a V-shaped cross section and pulled out.

〔Example〕

As shown in FIG. 1, there is a groove 2 in the center of the upper surface of the receiver 1.
As shown in FIG. 4, this groove 2 is formed so that the included angle a on the other side is gradually larger than the included angle b on one side, and the included angle on the one side 3 is a desired angle c, and the included angle on the other side is The included angle of end 4 is 180°. For this reason, a recess 6 is formed at the other side end 4 and has a width approximately equal to the width of the corrosion prevention band plate 5 (hereinafter referred to as "band plate") connected to the groove 2.

The lid 7 of the receiver 1 is rotatably connected to the sides of the upper surface of the receiver 1, and has a protrusion 8 formed in the center of the upper surface that fits into the groove 2. This protrusion 8 is formed so that the included angle a on the other side is gradually larger than the included angle b on one side, and the included angle on the one side end 9 is set to a desired degree c, and the included angle on the other side end 10 is set to a desired degree c.
The included angle is 180°.

Further, a guide hole 11 is formed in the receiver 1, and a protrusion 1 to be inserted into the guide hole 11 is formed in the lid body 7.
2 is provided, and a finger hook 13 for opening and closing the lid body 7 is further provided.

The strip plate 5 has a triangular protrusion 5 on one side of the flexible plate.
After bending, the triangular protrusion 5a is wrapped around the trunk, branch, etc. of a tree with the triangular protrusion 5a facing outward, thereby preventing damage from being eaten by wild animals such as hares, deer, and field mice. It is.

Therefore, as shown in FIG. 2, the receiver 1 and the lid 7
In the open state, the end of the band plate 5 projects slightly from one side 3, and after placing the other side in the recess 6, the lid 7 is closed. After setting in this way, as shown in FIG. 3, when one side end of the flat strip 5 is pulled, the strip 5 is first sandwiched between the receiver 1 and the lid 7, and as shown in FIG. 4A. The flat strip 5 becomes a V-shape with an included angle a, and when the strip 5 is further pulled, it becomes a V-shape with an included angle b as shown in FIG. The cross section has a V-shape with an included angle c.

As described above, the groove 2 is provided in the receiver 1, the protrusion 8 is provided in the lid 7, and the groove 2 and the protrusion 8 allow the band plate 5 to
can be easily bent.

Furthermore, since the receiver 1 and the lid 7 are connected to each other so that they can be opened and closed, there is no possibility that either one of them will be lost, resulting in excellent portability.

Moreover, the other end 4 of the groove 2 and the other end 10 of the protrusion 8
By setting the included angle to 180 degrees, when the band plate 5 is set, the band plate 5 is fitted into the groove 2 at a predetermined position, so that the band plate 5 can be reliably set with one touch.

[Effect of idea]

This device consists of a receiver for a strip plate for preventing feeding damage and a lid rotatably connected to the sides of the upper surface of the receiver, and a groove in the receiver that gradually increases the included angle from one side to the other. , and a protrusion whose included angle gradually increases from one side to the other side is formed on the lid body, so that it is possible to easily insert a band plate for preventing feeding damage. Furthermore, the included angle of the corrosion damage prevention strip is the same as the included angle of the groove and the protrusion, so that the corrosion damage prevention strip having an accurate included angle can be easily drawn out by hand.

Further, the corrosion prevention band plate is not processed all at once, but is processed so that the included angle gradually increases. Therefore, there is no possibility that the feeding damage prevention band plate will be cut in the middle. Furthermore, by making the included angle of the groove and the other end of the protrusion 180 degrees, that is, horizontal, the strip for preventing feeding damage can be easily set. Furthermore, since the receiver and the lid are connected so that they can be opened and closed, there is no chance of losing one of them, resulting in excellent portability.
