Arranged at equal pitches in the left-right direction and a plurality of horizontal wire rods 5, 5,. .. and are fixed in a grid pattern.

  Here, the front-rear direction means the front-rear direction in which a beast entering the field or pasture land moves, and the intrusion direction is the front and the opposite direction is the rear. Moreover, the left-right direction means the left-right direction when looking forward.

  The wire mesh 3 is in a state where the plurality of vertical wires 4 are bent so as to be at the highest position in the midway position T in the front-rear direction. As shown in FIG. 1, 14 vertical wires 4 are arranged in the left-right direction, and the midway position T in the front-rear direction is the highest position.

  Each vertical wire 4 is formed integrally with an inclined portion 4a extending from the rear side end portion to the midway position T in the front-rear direction and a support portion 4b extending downward from the midway position T in the front-rear direction of the inclined portion 4a. . Seven horizontal wire rods 5 are arranged as a whole of the wire mesh 3, and each horizontal wire rod 5 is in a state of not protruding in the left-right direction than the respective vertical wire rods 4 positioned at the left end and the right end. It is good also as a state which protrudes.

  In the wire mesh 3, the number of the vertical wires 4 and the horizontal wires 5 to be arranged is set as appropriate based on the size of the fields and pastures and the environment of the pastures.

  The vertical wire 4 and the horizontal wire 5 are rigid wires. For example, stainless steel wires or iron wires, or those obtained by applying chrome plating or zinc plating to these wires are used. Moreover, the vertical wire 4 and the horizontal wire 5 have a diameter of 3 mm to 8 mm and a tensile strength of 500 to 2000 N / mm 2. Note that the “rigid wire” means a material that can hold an arbitrary shape by itself.

  The interval W1 between the adjacent vertical wires 4 in the left-right direction is set to 6 to 10 cm (see FIG. 2A), and the interval L1 between the adjacent horizontal wires 5 in the front-rear direction is set to 5 to 15 cm (see FIG. 2). 2 (b)). The interval W1 or L1 is an interval at which beasts such as deer, foxes and foxes can slip into the space formed by the adjacent vertical wire 4 and the adjacent horizontal wire 5, It is set as appropriate by experiments.

  Four horizontal wires 5 are spanned across the inclined portions 4a of the plurality of vertical wires 4 at an interval L1 in the front-rear direction. Each horizontal wire 5 is located in the lower part of each inclined part 4a, and each intersection of inclined part 4a and horizontal wire 5 is fixed by welding.

  Of the wire mesh 3, a portion formed by the plurality of inclined portions 4 a and the plurality of horizontal wires 5 at which the intersections are fixed, that is, a portion on the rear side of the midway position T in the front-rear direction is the fence main body portion 1. The fence main body portion 1 has two reinforcing horizontal wires 6 for front and rear, which are spanned in parallel with the horizontal wires 5 at the rear end portions of the plurality of inclined portions 4a.

  The reinforcing horizontal wire 6 is the same as the horizontal wire 5 and is positioned below each inclined portion 4a. Intersections between the respective inclined portions 4a and the two reinforcing horizontal wires 6 are fixed by welding.

  The fence main body 1 has anchor wires 7 spanned between the inclined portions 4a between the horizontal wire 5 located at the rear end and the adjacent horizontal wire 5.

  The anchor wire 7 is positioned below the plurality of inclined portions 4a, and includes two inclined portions 4a positioned at the left end, two inclined portions 4a positioned at the right end, and two inclined portions 4a positioned at the center. The intersections with a total of six inclined portions 4a are fixed by welding.

  The anchor wire 7 is cut at two places between the left end and the center, and between the center and the right end, and is bent at a fixed intersection with the inclined portion 4a so that the cut end is positioned below the ground. It is in the state that was.

  As described above, the anchor wire 7 is fixed at the intersection of a total of six inclined portions 4a located at the left end, the center, and the right end among the plurality of inclined portions 4a. It does not restrict, What is necessary is just to be fixed at the intersection of some inclination parts 4a among some inclination parts 4a.

  Moreover, although the anchor wire 7 is bent at intersections with some of the plurality of inclined portions 4a, the bending position is not particularly limited as long as the cut end is positioned below the ground. Since the anchor wire 7 is bent at intersections with some of the plurality of inclined portions 4a, the cut end of the anchor wire 7 can be positioned further below the ground, which is preferable.

  Three horizontal wires 5 are spanned across the support portions 4b of the plurality of vertical wires 4 of the wire mesh 3 in the vertical direction at the interval L1 (see FIG. 2C). The horizontal wire 5 is located on the inclined portion 4a side with respect to each support portion 4b, and the intersections of the support portion 4b and the horizontal wire 5 are fixed by welding.

  Of the wire mesh 3, a portion formed by the plurality of support portions 4 b and the plurality of horizontal wires 5 at which the intersections are fixed, that is, the remaining portion other than the fence main body portion 1 is the fence support portion 2. The fence support part 2 has the insertion end part 4c with respect to the support part 4b arrange | positioned for every 3rd from the left-right direction both ends and the left-right direction both ends inward in the left-right direction among several support parts 4b.

  The insertion end portion 4c is configured by an extended portion extending downward from the lower end of the support portion 4b, and is formed integrally with the support portion 4b. The insertion end 4c has a length that can be inserted into the ground to regulate the movement of the fence support 2 and is set to 10 to 15 cm, for example.

  In addition, as shown in FIG. 1, the insertion end portion 4 c is out of the plurality of support portions 4 b with respect to the support portions 4 b arranged in the left-right direction both ends and from the left-right direction both ends inward in the left-right direction. Have. However, the present invention is not limited to this, and for example, it may be provided for each predetermined number or only at both ends. In short, what is necessary is just to have the number which can control the movement of the fence support part 2.

  The animal intrusion prevention fence shown in this embodiment has the above-described configuration. The fence main body 1 and the fence support 2 are formed by a wire mesh 3 bent upward at a midway position T in the front-rear direction, and the fence main body 1 is inclined upward toward the front. For this reason, as shown in FIG. 3, beasts such as deer, sharks, and moths are in a state where their feet enter a portion near the rear end of the fence main body 1 when entering a field or pasture.

By the way, it is known that beasts such as deer, sharks, and moths have a habit of hating foreign objects from touching their feet. In this embodiment, when the foot of the animal enters the portion near the rear end of the fence main body 1, the inclined part 4 a of the vertical wire 4 or the horizontal wire 5 comes into contact with the foot. Intrusion into the ground can be effectively prevented.

  In addition, the animal intrusion prevention fence shown in this embodiment can be easily installed around the fields and pastures only by arranging them around the fields and pastures, and the installation workability is improved. It will be good.
