しかしながら、特許文献１に記載のような従来の弾性ポールでは、別の径である外部支柱と内部支柱とが別体に設けられるものであり、外部支柱の外径が異なるものである場合には内部支柱も別途成形する必要があり、外部支柱及び内部支柱の成形に係わる作業が煩瑣となるものであった。   However, in the conventional elastic pole as described in Patent Document 1, the external struts having different diameters and the internal struts are provided separately, and the external struts have different outer diameters. The internal struts also need to be molded separately, and the work related to the molding of the external struts and the internal struts becomes cumbersome.

本発明は上記の如き課題に鑑みてなされたものであり、外部支柱の外径が異なるものであっても、内部支柱の形成に係わる作業を簡便なものとできる弾性ポールの形成方法を提供せんとするものである。   The present invention has been made in view of the above problems, and does not provide a method for forming an elastic pole that can simplify the work related to the formation of the internal support even if the outer diameter of the external support is different. It is what.

上記目的を達成するため、本発明は以下のような構成としている。すなわち、本発明に係わる弾性ポールの形成方法は、地表面に固着されるベース部と、ベース部から上方に突出されて設けられる可とう性の外部支柱と、外部支柱の内部に可とう性の内部支柱とを備える、大きい外径の弾性ポールと小さい外径の弾性ポールを含む少なくとも二種類の弾性ポールの形成方法であって、該外部支柱を上端から下端まで同一の外径の円筒状の成形品を用いて形成し、小さい外径の弾性ポールの外部支柱と大きい外径の弾性ポールの内部支柱を、一種類の外径の円筒状の成形品を用いて形成すると共に、小さい外径の弾性ポールの外部支柱と大きい外径の弾性ポールの内部支柱とを、いずれも各々のベース部に設けられた取付溝にその下端を挿入して回転融着によって固着するようにしたことを特徴とするものである。 In order to achieve the above object, the present invention is configured as follows. That is, the method for forming an elastic pole according to the present invention includes a base portion fixed to the ground surface, a flexible external strut that protrudes upward from the base portion, and a flexible inside the external strut. A method of forming at least two types of elastic poles including a large outer diameter elastic pole and a small outer diameter elastic pole with an inner column, the outer column having a cylindrical shape with the same outer diameter from the upper end to the lower end Formed using a molded product, and formed the outer strut of a small outer diameter elastic pole and the inner strut of a large outer diameter elastic pole using a single cylindrical molded product of one outer diameter and a small outer diameter Both of the outer pole of the elastic pole and the inner pole of the elastic pole with a large outer diameter are fixed by rotational fusion by inserting their lower ends into the mounting grooves provided in the respective base portions. Is what .

本発明に係わる弾性ポールの形成方法によれば、小さい外径の外部支柱を大きい外径の内部支柱として用いることで、異なる外部支柱の外径のものについて、内部支柱の形成に係わる作業を簡便なものとすることができる。   According to the method of forming an elastic pole according to the present invention, by using an external support column having a small outer diameter as an internal support column having a large outer diameter, the work related to the formation of the internal support can be easily performed on the external columns having different outer diameters. Can be.

Can be.

本発明に係わる最良の実施の形態について、図面に基づき以下に具体的に説明する。   BEST MODE FOR CARRYING OUT THE INVENTION The best embodiment according to the present invention will be specifically described below with reference to the drawings.

図１及び図２は、本発明に係わる弾性ポールの形成方法により形成された弾性ポールの一例を示すもので、図１は弾性ポールの正面図であり、（ａ）は大きい外径の弾性ポール、（ｂ）は小さい外径の弾性ポールである。大きい外径の弾性ポール１０Ａ及び小さい外径の弾性ポール１０Ｂは、いずれも路面に固着されるベース３の上方に外部支柱１Ａ及び１Ｂが突出されて設けられ、外部支柱１の上端はキャップ４により閉塞されると共に、外部支柱１Ａ及び１Ｂの上方付近には帯状の反射シートＲが巻回されて貼着されている。外部支柱１Ａの外径は１３０ｍｍとなされ、外部支柱１Ｂの外径は８０ｍｍであり、いずれも上端から下端まで同一の外径及び肉厚の円筒状の成形品を用いているものである。また外部支柱１Ａ及び１Ｂは、いずれも可とう性の合成樹脂であるポリウレタン系樹脂からなるものであり、ベース３及びキャップ４についても同じ材料を用いて形成されている。   1 and 2 show an example of an elastic pole formed by the method of forming an elastic pole according to the present invention. FIG. 1 is a front view of the elastic pole, and (a) is an elastic pole having a large outer diameter. , (B) are elastic poles having a small outer diameter. Both the large outer diameter elastic pole 10A and the small outer diameter elastic pole 10B are provided with external columns 1A and 1B protruding above the base 3 fixed to the road surface. In addition to being closed, a strip-shaped reflection sheet R is wound and stuck near the upper portion of the external support columns 1A and 1B. The outer strut 1A has an outer diameter of 130 mm, and the outer strut 1B has an outer diameter of 80 mm. All of the outer struts 1A are cylindrical molded products having the same outer diameter and thickness from the upper end to the lower end. Each of the external struts 1A and 1B is made of a polyurethane-based resin that is a flexible synthetic resin, and the base 3 and the cap 4 are also formed using the same material.

次に図２において、大きい外径の弾性ポール１０Ａ、及び小さい外径の弾性ポール１０Ｂはいずれも外部支柱１Ａ及び１Ｂの内側に、内部支柱２Ａ及び２Ｂが設けられている。内部支柱２Ａの外径は８０ｍｍ、内部支柱２Ｂの外径は６０ｍｍであり、いずれも上端から下端まで同一の外径及び肉厚の円筒状の成形品であり、且つ外部支柱１と同じポリウレタン系樹脂からなるものである。外部支柱１及び内部支柱２は、いずれもベース３に設けられた取付溝３１に下端が挿入されて回転融着により強固に固着されているが、内部支柱２Ａと外部支柱１Ｂとが同一の外径、肉厚及び材質であることから、４種類の外部支柱１Ａ及び１Ｂ、並びに内部支柱２Ａ及び２Ｂの形成に３種類の円筒状の成形体を用いて形成することができ、内部支柱の形成に係わる作業が簡便となるようになされている。   Next, in FIG. 2, both the large outer diameter elastic pole 10 </ b> A and the small outer diameter elastic pole 10 </ b> B are provided with the inner columns 2 </ b> A and 2 </ b> B inside the outer columns 1 </ b> A and 1 </ b> B. The inner strut 2A has an outer diameter of 80 mm, and the inner strut 2B has an outer diameter of 60 mm, both of which are cylindrical molded products having the same outer diameter and thickness from the upper end to the lower end, and the same polyurethane system as the outer strut 1 It consists of resin. The outer support column 1 and the inner support column 2 are both firmly fixed by rotational fusion with the lower end inserted into the mounting groove 31 provided in the base 3, but the inner support column 2A and the outer support column 1B are the same outside. Because of the diameter, thickness, and material, it is possible to form the four types of external struts 1A and 1B and the internal struts 2A and 2B by using three types of cylindrical molded bodies. The work related to is made easy.

本発明に係わる弾性ポールの形成方法は、二種類の外径の弾性ポールに限定されるものではなく、三種類以上の外径を有する弾性ポールに適用することも可能であり、その場合は外径の大きい弾性ポールの外部支柱の内径より小さい内部支柱を、外径の小さい弾性ポールの外部支柱から適宜選択して内部支柱として用いるようにすればよい。   The method of forming an elastic pole according to the present invention is not limited to two types of outer diameter elastic poles, but can be applied to an elastic pole having three or more types of outer diameters. An internal column smaller than the inner diameter of the outer pole of the elastic pole having a larger diameter may be appropriately selected from the outer columns of the elastic pole having a smaller outer diameter and used as the inner column.
