［第１実施形態］
図１は、本発明の一実施形態の侵入防止器を示す斜視図である。この侵入防止器１０は、板体（板状部材）１に多数の突片２が形成されてできている。突片２は、板体１の両側の長手方向辺部に沿って、等間隔に、並んで立っている。突片２の先端は尖っている。なお、板体１の構成材料としては、例えば、ポリ塩化ビニル（ＰＶＣ）、ポリエチレン（ＰＥ）、ポリプロピレン（ＰＰ）等の、合成樹脂；アルミニウム等の加工しやすい金属材料；を使用できるが、特に、耐衝撃性・耐熱性・難燃性・寸安定性・耐候性等において優れた物性を示すポリカーボネート（ＰＣ）を使用するのが好ましい。 [First Embodiment]
FIG. 1 is a perspective view showing an intrusion prevention device according to an embodiment of the present invention. The intrusion prevention device 10 is formed by forming a large number of projecting pieces 2 on a plate body (plate-shaped member) 1. The projecting pieces 2 stand side by side at equal intervals along the longitudinal side portions on both sides of the plate body 1. The tip of the projectile 2 is sharp. As the constituent material of the plate body 1, for example, a synthetic resin such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP); a metal material which is easy to process such as aluminum; can be used, but in particular. It is preferable to use polypropylene (PC), which exhibits excellent physical properties in terms of impact resistance, heat resistance, flame retardancy, dimensional stability, weather resistance, and the like.

この侵入防止器１０は、図２に示されるような、多数の切り込み線３が形成された板体１から作製される。図３は、図２の板体１の拡大部分図である。板体１は、第１長手方向辺部１１と第２長手方向辺部１２とを有している。両辺部１１、１２は平行関係を有している。 The intrusion prevention device 10 is made of a plate body 1 on which a large number of cut lines 3 are formed, as shown in FIG. FIG. 3 is an enlarged partial view of the plate body 1 of FIG. The plate body 1 has a first longitudinal side portion 11 and a second longitudinal side portion 12. Both side portions 11 and 12 have a parallel relationship.

第１長手方向辺部１１には、多数の切り込み線３が形成されている。切り込み線３は、板体１の長手方向（Ｙ方向）に対して傾斜しており、且つ、互いに平行に形成されている。切り込み線３は、第１長手方向辺部１１の縁から板体１の幅Ｗの中間点Ｃより少し手前の位置までの、長さＬ１を、有している。 A large number of cut lines 3 are formed on the first longitudinal side portion 11. The cut line 3 is inclined with respect to the longitudinal direction (Y direction) of the plate body 1 and is formed parallel to each other. The cut line 3 has a length L1 from the edge of the first longitudinal side portion 11 to a position slightly before the midpoint C of the width W of the plate body 1.

第２長手方向辺部１２にも、多数の切り込み線３が形成されている。切り込み線３は、板体１の長手方向（Ｙ方向）に対して傾斜しており、且つ、互いに平行に形成されている。なお、第１長手方向辺部１１に形成された切り込み線３と、第２長手方向辺部１２に形成された切り込み線３とは、同一直線Ｓ上に位置している。切り込み線３は、第２長手方向辺部１２の縁から板体１の幅Ｗの中間点Ｃより少し手前の位置までの、長さＬ１を、有している。 A large number of cut lines 3 are also formed on the second longitudinal side portion 12. The cut line 3 is inclined with respect to the longitudinal direction (Y direction) of the plate body 1 and is formed parallel to each other. The cut line 3 formed in the first longitudinal side portion 11 and the cut line 3 formed in the second longitudinal side portion 12 are located on the same straight line S. The cut line 3 has a length L1 from the edge of the second longitudinal side portion 12 to a position slightly before the midpoint C of the width W of the plate body 1.

よって、板体１は、切り込み線３の無い無垢部３０を、幅方向中央部に、且つ、長手方向に延びて、有している。 Therefore, the plate body 1 has a solid portion 30 without a notch line 3 extending in the central portion in the width direction and in the longitudinal direction.

第１長手方向辺部１１及び第２長手方向辺部１２には、隣接する切り込み線３によって、線間部分４が形成されている。線間部分４は、多数形成されている。線間部分４は、板体１の幅方向（Ｘ方向）外側に、鋭角頂点部４１と鈍角頂点部４２とを有している。 An interline portion 4 is formed in the first longitudinal side portion 11 and the second longitudinal side portion 12 by the adjacent cut lines 3. A large number of interline portions 4 are formed. The line-to-line portion 4 has an acute-angle apex portion 41 and an obtuse-angle apex portion 42 on the outside in the width direction (X direction) of the plate body 1.

そして、突片２は、多数の線間部分４を立ち上げることによって、形成されている。突片２は、鋭角頂点部４１が上方に向くように、線間部分４を、鋭角頂点部４１側の切り込み線３の内部端３１と鈍角頂点部４２とを結ぶ仮想線Ｋに沿って折り曲げることによって、形成されている。例えば、図３の第１長手方向辺部１１の線間部分４を矢印Ｒ１のように折り曲げると、図４に示されるように、線間部分４が立ち上がって突片２となる。また、図３の第２長手方向辺部１２の線間部分４を矢印Ｒ２のように折り曲げると、図４に示されるように、線間部分４が立ち上がって突片２となる。図５は、図１の拡大部分図である。図５に示されるように、両辺部１１、１２の多数の線間部分４が立ち上げられることによって、多数の突片２が形成されている。 The projecting piece 2 is formed by raising a large number of interlined portions 4. The projecting piece 2 bends the line-to-line portion 4 along the virtual line K connecting the internal end 31 of the cut line 3 on the acute-angle apex 41 side and the obtuse-angle apex 42 so that the acute-angle apex 41 faces upward. It is formed by that. For example, when the line-to-line portion 4 of the first longitudinal side portion 11 in FIG. 3 is bent as shown by an arrow R1, the line-to-line portion 4 rises to form a projecting piece 2 as shown in FIG. Further, when the line-to-line portion 4 of the second longitudinal side portion 12 of FIG. 3 is bent as shown by the arrow R2, the line-to-line portion 4 rises to become a projecting piece 2 as shown in FIG. FIG. 5 is an enlarged partial view of FIG. As shown in FIG. 5, a large number of projecting pieces 2 are formed by raising a large number of interlined portions 4 of both side portions 11 and 12.

上記構成の侵入防止器１０によれば、次のような効果を発揮できる。
（１）先端の尖った突片２を長手方向に沿って多数有しているので、侵入防止の境界線としての機能を、長手方向の長さ寸法分だけ、簡単に発揮できる。 According to the intrusion prevention device 10 having the above configuration, the following effects can be exhibited.
(1) Since a large number of projecting pieces 2 having sharp tips are provided along the longitudinal direction, the function as an intrusion prevention boundary line can be easily exerted by the length dimension in the longitudinal direction.

（２）多数の突片２を長手方向に等間隔に有しているので、一定以上の寸法の小動物等が侵入するのを防止できる。 (2) Since a large number of projecting pieces 2 are provided at equal intervals in the longitudinal direction, it is possible to prevent small animals having a certain size or more from invading.

（３）第１長手方向辺部１１だけでなく、第２長手方向辺部１２においても、多数の突片２を長手方向に有しているので、侵入防止の境界線としての機能を、二重に発揮できる。 (3) Not only the first longitudinal side portion 11 but also the second longitudinal side portion 12 has a large number of projecting pieces 2 in the longitudinal direction, so that the function as a boundary line for intrusion prevention can be achieved. It can be demonstrated heavily.

（４）突片２を両辺部１１、１２に有しているので、板体１の所定の長さ寸法において、より多くの突片２を有することができる。よって、侵入防止機能をより効果的に発揮できる。 (4) Since the projecting pieces 2 are provided on both side portions 11 and 12, more projecting pieces 2 can be provided in a predetermined length dimension of the plate body 1. Therefore, the intrusion prevention function can be exhibited more effectively.

（５）両辺部１１、１２に多数の切り込み線３を形成し、多数の線間部分４を折り曲げるだけで、多数の突片２を形成できるので、侵入防止器１０を容易に作製できる。 (5) Since a large number of projecting pieces 2 can be formed only by forming a large number of cut lines 3 on both side portions 11 and 12 and bending a large number of interline portions 4, the intrusion preventer 10 can be easily manufactured.

（６）切り込み線３が両辺部１１、１２の縁から形成されているので、線間部分４を外側から立ち上げることができる。よって、この点からも、侵入防止器１０を容易に作製できる。 (6) Since the cut line 3 is formed from the edges of both side portions 11 and 12, the line-to-line portion 4 can be raised from the outside. Therefore, from this point as well, the intrusion prevention device 10 can be easily manufactured.

（７）両辺部１１、１２の各切り込み線３が同一直線Ｓ上に位置しているので、両辺部１１、１２の突片２を、長手方向において、等間隔に且つ最多数、形成できる。すなわち、突片２を、単位長さ当たりの数が最大となるように形成できる。よって、侵入防止の効果をより良好に発揮できる。 (7) Since the cut lines 3 of both side portions 11 and 12 are located on the same straight line S, the projecting pieces 2 of both side portions 11 and 12 can be formed at equal intervals and in the maximum number in the longitudinal direction. That is, the projecting pieces 2 can be formed so that the number per unit length is maximized. Therefore, the effect of preventing intrusion can be more effectively exhibited.

（ｂ）第１長手方向辺部１１の切り込み線３の長さと第２長手方向辺部１２の切り込み線３の長さとが異なっている。 (B) The length of the cut line 3 of the first longitudinal side portion 11 and the length of the cut line 3 of the second longitudinal side portion 12 are different.

（ｃ）図７に示されるように、両辺部１１、１２の各切り込み線３が同一直線Ｓ上に位置していない。 (C) As shown in FIG. 7, the cut lines 3 of the side portions 11 and 12 are not located on the same straight line S.

（ｄ）仮想線Ｋが、図４の仮想線Ｋ１〜Ｋ４に示されるように、内部端３１の近傍と鈍角頂点部４２の近傍とを結んでいる。なお、仮想線Ｋは、第１実施形態に示されるように、内部端３１と鈍角頂点部４２とを正確に結ぶのが、好ましい。 (D) As shown by the virtual lines K1 to K4 in FIG. 4, the virtual line K connects the vicinity of the inner end 31 and the vicinity of the obtuse angle apex portion 42. As shown in the first embodiment, the virtual line K preferably connects the inner end 31 and the obtuse angle apex 42 accurately.

（ｅ）突片２が、第１長手方向辺部１１のみに、又は、第２長手方向辺部１２のみに、形成されている。 (E) The projecting piece 2 is formed only on the first longitudinal side portion 11 or only on the second longitudinal side portion 12.

本発明の侵入防止器は、容易に作製でき、しかも、板状部材の単位長さ当たりの突起の数を増大して侵入防止機能を効果的に発揮できるので、産業上の利用価値が大である。 The intrusion prevention device of the present invention can be easily manufactured, and moreover, the number of protrusions per unit length of the plate-shaped member can be increased to effectively exert the intrusion prevention function, so that it has great industrial utility value. is there.
