本発明の進入防止部材及び視線誘導柱の好適な実施形態を、図面を用いて説明する。図１は、進入防止部材が取り付けられた視線誘導柱の平面図及び正面図である。図２は、図１に示す進入防止部材及び視線誘導柱のＡ−Ａ断面図である。 A preferred embodiment of the entry prevention member and the line-of-sight guide column of the present invention will be described with reference to the drawings. FIG. 1 is a plan view and a front view of a line-of-sight guide pillar to which an entry prevention member is attached. FIG. 2 is a cross-sectional view taken along the line AA of the entry prevention member and the line-of-sight guide column shown in FIG.

進入防止部材１は、視線誘導柱２の上部に取り付けられるものである。進入防止部材１は、視線誘導柱２の上部外周面２ａに取り付けられる筒状部１０と、筒状部１０から水平方向に延びる長尺状部１１と、を備える。 The entry prevention member 1 is attached to the upper part of the line-of-sight guide pillar 2. The entry prevention member 1 includes a tubular portion 10 attached to the upper outer peripheral surface 2a of the line-of-sight guide pillar 2, and an elongated portion 11 extending in the horizontal direction from the tubular portion 10.

筒状部１０は、円柱状の視線誘導柱２に対応するように、円筒状に形成されている。勿論、視線誘導柱２が角柱や楕円柱である場合には、その形状に応じて筒状部１０は角筒状又は楕円筒状に形成される。筒状部１０の内径は、視線誘導柱２の外径に一致又は少し小さく形成されている。 The tubular portion 10 is formed in a cylindrical shape so as to correspond to the columnar line-of-sight guide column 2. Of course, when the line-of-sight guide pillar 2 is a prism or an elliptical pillar, the tubular portion 10 is formed into a prismatic or elliptical cylinder depending on the shape. The inner diameter of the tubular portion 10 is formed to match the outer diameter of the line-of-sight guide column 2 or to be slightly smaller.

本実施形態の筒状部１０は、筒状部１０の上部開口を閉塞する蓋部１２を有している。ただし、この蓋部１２は、必ずしも設ける必要はなく、また、筒状部１０の上部開口を部分的に閉塞する形状でもよい。 The tubular portion 10 of the present embodiment has a lid portion 12 that closes the upper opening of the tubular portion 10. However, the lid portion 12 does not necessarily have to be provided, and may have a shape that partially closes the upper opening of the tubular portion 10.

長尺状部１１は、筒状部１０から水平方向に延びている。本実施形態の長尺状部１１は、筒状部１０の上部から水平方向両側にそれぞれ延びている。長尺状部１１は、その長手方向中央部が筒状部１０の上端に固定されている。 The elongated portion 11 extends horizontally from the tubular portion 10. The elongated portion 11 of the present embodiment extends from the upper portion of the tubular portion 10 to both sides in the horizontal direction. The central portion of the elongated portion 11 in the longitudinal direction is fixed to the upper end of the tubular portion 10.

本実施形態の長尺状部１１は、断面が三角形状となっており、この三角形の底辺が筒状部１０の上端に固定されている。また、長尺状部１１は、長手方向に延びる中空部１１０を有しており、全体として断面三角形状の中空パイプとなっている。 The elongated portion 11 of the present embodiment has a triangular cross section, and the base of the triangle is fixed to the upper end of the tubular portion 10. Further, the elongated portion 11 has a hollow portion 110 extending in the longitudinal direction, and is a hollow pipe having a triangular cross section as a whole.

本発明の進入防止部材１によれば、筒状部１０を視線誘導柱２の上部外周面２ａに取り付けるだけで、進入防止部材１の視線誘導柱２への取付が可能となるため、既設の視線誘導柱にも容易に適用できる。また、長尺状部１１が筒状部１０から水平方向に延びているため、視認性が良く、適切に注意喚起を促すことができる。長尺状部１１の側面には、さらなる注意喚起を促すための反射シート（図示せず）が貼付されてもよい。 According to the entry prevention member 1 of the present invention, the entry prevention member 1 can be attached to the line-of-sight guide pillar 2 simply by attaching the tubular portion 10 to the upper outer peripheral surface 2a of the line-of-sight guide pillar 2. It can be easily applied to the line-of-sight guide column. Further, since the elongated portion 11 extends in the horizontal direction from the tubular portion 10, the visibility is good and it is possible to appropriately call attention. A reflective sheet (not shown) may be attached to the side surface of the elongated portion 11 to call for further attention.

筒状部１０、長尺状部１１、及び蓋部１２を含む進入防止部材１を構成する全ての部材は非金属材料で形成されている。具体的には、エラストマー系樹脂で形成されているが、その他の樹脂も利用可能である。 All the members constituting the entry prevention member 1 including the tubular portion 10, the elongated portion 11, and the lid portion 12 are made of a non-ferrous material. Specifically, it is made of an elastomeric resin, but other resins can also be used.

筒状部１０と長尺状部１１は、一体化されている。長尺状部１１は、筒状部１０の上端に対して、接着剤による接着や、超音波溶着又は熱溶着で固定される。 The tubular portion 10 and the elongated portion 11 are integrated. The elongated portion 11 is fixed to the upper end of the tubular portion 10 by adhesion with an adhesive, ultrasonic welding, or heat welding.

長尺状部１１の長さは、２０００ｍｍ以下が好ましく、１０００ｍｍ以下が特に好ましい。長尺状部１１の長さを長くし過ぎると、自重により撓みやすくなる。また、本実施形態の長尺状部１１の断面は、正三角形の一辺、もしくは二等辺三角形の底辺が３０〜８０ｍｍの三角形としている。また、中空パイプ状の長尺状部１１の肉厚は、２〜４ｍｍとしている。 The length of the elongated portion 11 is preferably 2000 mm or less, and particularly preferably 1000 mm or less. If the length of the elongated portion 11 is made too long, it tends to bend due to its own weight. Further, the cross section of the elongated portion 11 of the present embodiment is a triangle having one side of an equilateral triangle or an isosceles triangle having a base of 30 to 80 mm. The wall thickness of the hollow pipe-shaped elongated portion 11 is 2 to 4 mm.

図３に示すように、進入防止部材１が取り付けられた視線誘導柱２は、長尺状部１１の先端１１ａに内挿又は外挿され、隣り合う進入防止部材１の長尺状部１１同士を連結する連結部材３をさらに備えてもよい。この実施形態の連結部材３は、両端が断面三角形状の中空パイプとなっており、その両端にそれぞれ長尺状部１１の先端１１ａを挿入することができる。
連結部材３の長さは、隣り合う視線誘導柱２に取り付けられた進入防止部材１の長尺状部１１同士の間隔よりも長くなっている。これにより、隣り合う進入防止部材１の長尺状部１１同士を連結することができ、注意喚起をより一層促すことができる。なお、本実施形態の視線誘導柱２には反射テープ２１を巻き付けて注意喚起をより一層促しているが、反射テープ２１の有無、位置、貼付範囲などは適宜変更可能である。 As shown in FIG. 3, the line-of-sight guide pillar 2 to which the entry prevention member 1 is attached is inserted or extrapolated into the tip end 11a of the elongated portion 11, and the elongated portions 11 of the adjacent entry prevention members 1 are inserted into each other. A connecting member 3 for connecting the above may be further provided. The connecting member 3 of this embodiment is a hollow pipe having a triangular cross section at both ends, and the tip 11a of the elongated portion 11 can be inserted into each of the both ends.
The length of the connecting member 3 is longer than the distance between the elongated portions 11 of the entry prevention members 1 attached to the adjacent line-of-sight guide columns 2. As a result, the elongated portions 11 of the adjacent entry prevention members 1 can be connected to each other, and the attention can be further urged. A reflective tape 21 is wrapped around the line-of-sight guide pillar 2 of the present embodiment to further call attention, but the presence / absence, position, sticking range, etc. of the reflective tape 21 can be changed as appropriate.

本実施形態の連結部材３は、長尺状部１１の先端１１ａを挿入する長さを変更可能なため、隣り合う長尺状部１１を必ずしも所定の間隔で精度良く配置する必要はなく、進入防止部材１が取り付けられた視線誘導柱２を容易に連続して配置することができる。 Since the connecting member 3 of the present embodiment can change the length into which the tip 11a of the elongated portion 11 is inserted, it is not always necessary to accurately arrange the adjacent elongated portions 11 at predetermined intervals, and the connecting member 3 enters. The line-of-sight guide pillar 2 to which the prevention member 1 is attached can be easily and continuously arranged.
