Description

本発明は、柱体の設置面に設置される被覆部材に関する。 The present invention relates to a covering member installed on an installation surface of a pillar.

道路脇等に、電柱、信号灯等の柱体が設置される。柱体の折損は、道路の封鎖、走行中の車両または人に対して被害をもたらす場合があることから、柱体の計画的な点検、立て替えによる安全性の確保が求められる（例えば非特許文献１参照）。 Pillars such as utility poles and signal lights will be installed on the side of the road. Since breakage of a pillar may cause damage to a road blockade, a moving vehicle or a person, it is required to ensure safety by systematically inspecting the pillar and replacing it (for example, non-patent documents). 1).

傾斜またはたわみ等の柱体の形状を測定する測定装置が知られている。このような測定装置は、柱体を側面から観察し、柱体の脇を基準マークに一致させて、柱体上の複数点をレーザー光により測定する。 A measuring device for measuring the shape of a pillar such as inclination or deflection is known. In such a measuring device, the pillar body is observed from the side surface, the side of the pillar body is aligned with the reference mark, and a plurality of points on the pillar body are measured by laser light.

また電柱等の設置面に雑草が繁殖しないように、電柱の設置面近傍を被覆する電柱カバーが知られている。 Further, a utility pole cover that covers the vicinity of the installation surface of the utility pole is known so that weeds do not grow on the installation surface of the utility pole or the like.

川端一嘉他６名、"作業の高効率化と高品質化を実現する基盤設備の点検診断技術"、［online］、2014年8月、NTT技術ジャーナル、［2019年2月25日検索］、インターネット〈URL： http://www.ntt.co.jp/journal/1408/files/jn201408022.pdf〉Kazuyoshi Kawabata and 6 others, "Inspection and diagnosis technology for basic equipment that realizes high work efficiency and quality", [online], August 2014, NTT Technical Journal, [Search on February 25, 2019] , Internet <URL: http://www.ntt.co.jp/journal/1408/files/jn201408022.pdf>

非特許文献１に記載されるように、柱体の管理が重要であるところ、適切に柱体の形状を測定できない場合がある。例えば、柱体の形状を測定する測定装置は、設置面において、雑草、草木の植え込み等の障害物があることから、柱体の脇を基準マークに一致させ、かつ柱体上の点を測定することが困難な場合がある。また一般的な電柱カバーは、電柱の設置面近傍に、ボルトとナットにより常設される。従って、個々の電柱のサイズに応じて電柱カバーを用意しなければならないこと、および、一時的な配置に不向きで常設しなければならないことから、コストがかかる場合がある。 As described in Non-Patent Document 1, where the management of the pillar is important, the shape of the pillar may not be measured appropriately. For example, a measuring device that measures the shape of a pillar has obstacles such as weeds and vegetation planted on the installation surface, so the side of the pillar matches the reference mark and the point on the pillar is measured. It can be difficult to do. A general utility pole cover is permanently installed with bolts and nuts near the installation surface of the utility pole. Therefore, it may be costly because the utility pole cover must be prepared according to the size of each utility pole and must be permanently installed because it is not suitable for temporary arrangement.

このように、柱体の形状を測定する測定装置等を用いた測定によって、柱体を容易に維持管理することは困難である。 As described above, it is difficult to easily maintain and manage the pillar body by measurement using a measuring device or the like for measuring the shape of the pillar body.

従って本発明の目的は、柱体を容易に維持管理可能な被覆部材を提供することである。 Therefore, an object of the present invention is to provide a covering member capable of easily maintaining and managing a pillar body.

上記課題を解決するために、本発明の第１の特徴は、柱体の設置面に設置される被覆部材に関する。本発明の第１の特徴に係る被覆部材は、自重により設置面の障害物を押さえる被覆部を備え、被覆部に、柱体の長さ方向の一部を収容する貫通穴と、貫通穴から被覆部の端部まで達する開口が設けられる。
被覆部は、弾性を有しても良い。 In order to solve the above problems, the first feature of the present invention relates to a covering member installed on the installation surface of the pillar. The covering member according to the first feature of the present invention is provided with a covering portion that holds down obstacles on the installation surface by its own weight, and the covering portion has a through hole for accommodating a part of the pillar in the length direction and a through hole.

開口を挟む被覆部の一対の端部を連結する開口連結部をさらに備えても良い。 An opening connecting portion that connects a pair of ends of the covering portion that sandwiches the opening may be further provided.

本発明の第２の特徴は、柱体の設置面に設置される被覆部材に関する。本発明の第２の特徴に係る被覆部材は、自重により設置面の障害物を押さえる複数の被覆部を備え、複数の被覆部はそれぞれ凹部を有し、凹部が隣接することにより、柱体の長さ方向の一部を収容する貫通穴が設けられる。 The second feature of the present invention relates to a covering member installed on the installation surface of the pillar body. The covering member according to the second feature of the present invention includes a plurality of covering portions that hold down obstacles on the installation surface by its own weight, each of the plurality of covering portions has a recess, and the recesses are adjacent to each other to form a pillar. A through hole is provided to accommodate a part in the length direction.

複数の被覆部を接続する接続部をさらに備えても良い。 Further, a connecting portion for connecting a plurality of covering portions may be provided.

本発明の第１の特徴および第２の特徴において、貫通穴から被覆部の端部までの第１の方向の距離は、第１の方向に直交する第２の方向の貫通穴から被覆部の端部までの距離よりも長くなるように形成されても良い。 In the first feature and the second feature of the present invention, the distance from the through hole to the end of the covering portion in the first direction is the distance from the through hole in the second direction orthogonal to the first direction to the covering portion. It may be formed so as to be longer than the distance to the end.

本発明の第１の特徴および第２の特徴において、被覆部の貫通穴に接する部分に、貫通穴の中心方向に伸縮する緩衝部材をさらに備えても良い。 In the first feature and the second feature of the present invention, a cushioning member that expands and contracts in the central direction of the through hole may be further provided at a portion of the covering portion in contact with the through hole.

本発明の第３の特徴は、測定支援システムに関する。第３の特徴に係る測定支援システムは、本発明の第１の特徴および第２の特徴に記載の被覆部材と、柱体の面に配設され、柱体の幅よりも大きく、柱体の脇の視認性を向上させる色を有する背景部材を備える。 The third feature of the present invention relates to a measurement support system. The measurement support system according to the third feature is arranged on the surface of the pillar with the covering member described in the first feature and the second feature of the present invention, and is larger than the width of the pillar and of the pillar.

（実施の形態）
図１を参照して、本発明の実施の形態に係る被覆部材１を説明する。被覆部材１は、図２に示すように、柱体７の設置面に設置される。本発明の実施の形態において柱体７は、電柱等の円柱形状である場合を説明するが、角柱形状、球体等の任意の形状であっても良い。 (Embodiment)
The covering member 1 according to the embodiment of the present invention will be described with reference to FIG. As shown in FIG. 2, the covering member 1 is installed on the installation surface of the pillar 7. In the embodiment of the present invention, the case where the pillar 7 has a cylindrical shape such as a utility pole will be described, but it may have any shape such as a prism shape or a sphere.

本発明の実施の形態において、Ｘ軸方向は、被覆部材１を上面から観察した際の被覆部材１の横方向であって、Ｙ軸方向は、縦方向である。またＺ軸方向は、被覆部材１の厚み方向であって、柱体７の長さ方向である。本発明の実施の形態において被覆部材１は、上面視で角を丸めた略矩形形状を有するが、矩形でなくても良い。 In the embodiment of the present invention, the X-axis direction is the lateral direction of the covering member 1 when the covering member 1 is observed from above, and the Y-axis direction is the vertical direction. The Z-axis direction is the thickness direction of the covering member 1 and is the length direction of the pillar 7. In the embodiment of the present invention, the covering member 1 has a substantially rectangular shape with rounded corners when viewed from above, but it does not have to be rectangular.

被覆部材１は、自重により設置面の障害物８を押さえる被覆部２を備える。本発明の実施の形態において障害物８は、雑草等である。本発明の実施の形態において被覆部２は、弾性を有する。被覆部２は、貫通穴３と開口４が設けられる。 The covering member 1 includes a covering portion 2 that holds down an obstacle 8 on the installation surface by its own weight. In the embodiment of the present invention, the obstacle 8 is a weed or the like. In the embodiment of the present invention, the covering portion 2 has elasticity. The covering portion 2 is provided with a through hole 3 and an opening 4.

貫通穴３は、柱体７の長さ方向の一部を収容する。貫通穴３は、ＸＹ平面において、柱体７の長さ方向に直交する面を収容可能に形成される。図２に示すように、貫通穴３に柱体７が通される。開口４は、貫通穴３から被覆部２の端部まで達するように形成される。開口４は、被覆部２を貫通し、開口４を挟む被覆部２の端部２ａおよび２ｂは、互いに離れるように形成される。 The through hole 3 accommodates a part of the pillar 7 in the length direction. The through hole 3 is formed so as to accommodate a plane orthogonal to the length direction of the pillar 7 in the XY plane. As shown in FIG. 2, the pillar 7 is passed through the through hole 3. The opening 4 is formed so as to reach from the through hole 3 to the end of the covering portion 2. The opening 4 penetrates the covering portion 2, and the ends 2a and 2b of the covering portion 2 sandwiching the opening 4 are formed so as to be separated from each other.

被覆部材１は、弾性を有することから、端部２ａおよび２ｂを捻る（Ｚ軸方向に互いに異なる方向に引く）ことにより、開口４を広く形成し、開口４を介して貫通穴３に、柱体７を通すことが可能になる。 Since the covering member 1 has elasticity, the ends 2a and 2b are twisted (pulled in different directions in the Z-axis direction) to form a wide opening 4, and the through hole 3 is formed through the opening 4 to form a column. It becomes possible to pass the body 7.

貫通穴３に柱体７が通された後、被覆部材１は、自重により柱体７の設置面近傍に設置される。被覆部材１は、柱体７の設置面近傍の障害物８を押し倒して、設置面近傍における柱体７を露出することができる。測定装置９により、設置面近傍の柱体７を観察することが可能になる。例えば測定装置９は、設置面近傍の柱体７の脇を基準マークに一致させて、設置面近傍の柱体７上の点をレーザー光により測定させることが可能になる。なお測定装置９は、Ｙ軸上（ＹＺ平面）でレーザー光を照射する。 After the pillar 7 is passed through the through hole 3, the covering member 1 is installed near the installation surface of the pillar 7 by its own weight. The covering member 1 can push down the obstacle 8 near the installation surface of the pillar 7 to expose the pillar 7 near the installation surface. The measuring device 9 makes it possible to observe the pillar 7 in the vicinity of the installation surface. For example, the measuring device 9 makes it possible to match the side of the pillar 7 near the installation surface with the reference mark and measure a point on the pillar 7 near the installation surface by laser light. The measuring device 9 irradiates the laser beam on the Y axis (YZ plane).

被覆部２は、図２に示すように、開口４部分において障害物８を押さえることができない。従って開口４部分から上方に伸びる障害物が、測定装置９から観察されにくいように、被覆部材１が設置されるのが好ましい。測定装置９は、貫通穴３に対して、開口４が設置された方向の反対方向に設置されるのが好ましい。また開口４は、測定装置９が照射する光軸上のＹＺ平面上に設置されるのが好ましい。 As shown in FIG. 2, the covering portion 2 cannot hold down the obstacle 8 at the opening 4 portion. Therefore, it is preferable to install the covering member 1 so that the obstacle extending upward from the opening 4 portion is not easily observed by the measuring device 9. The measuring device 9 is preferably installed in the direction opposite to the direction in which the opening 4 is installed with respect to the through hole 3. Further, the opening 4 is preferably installed on the YZ plane on the optical axis irradiated by the measuring device 9.

本発明の実施の形態において被覆部２は、ゴム、織物等の密度が高く、弾性を有する材料により形成される。被覆部２は、自重により障害物８を押さえることから、障害物８を押さえることが可能な重さが必要になる。また、柱体７の設置面近傍を測定するためには、被覆部材１の厚み（Ｚ軸方向の長さ）は、小さい方が好ましい。これらのことから、被覆部材１には、密度の高い材料が好適である。なお被覆部２の材料に求められる密度は、柱体７におけるＺ軸方向の測定位置、障害物８の強度、被覆部２の形状等によって、被覆部２の上端が、Ｚ軸方向の測定位置よりも下方に位置するように、適宜定められる。 In the embodiment of the present invention, the covering portion 2 is formed of a material having high density and elasticity such as rubber and woven fabric. Since the covering portion 2 presses the obstacle 8 by its own weight, a weight capable of holding the obstacle 8 is required. Further, in order to measure the vicinity of the installation surface of the pillar body 7, it is preferable that the thickness (length in the Z-axis direction) of the covering member 1 is small. From these facts, a material having a high density is suitable for the covering member 1. The density required for the material of the covering portion 2 depends on the measurement position in the Z-axis direction of the pillar 7, the strength of the obstacle 8, the shape of the covering portion 2, and the like, and the upper end of the covering portion 2 is the measuring position in the Z-axis direction. It is appropriately determined so that it is located below.

被覆部材１は、測定時に柱体７に巻き付けて、測定後に容易に取り外すことが可能であるので、可搬性に優れており、各地に転々と配設される柱体７の測定に好適である。また被覆部材１は弾性を有するので、柱体７の径と貫通穴３の径に差異があっても、適用することができる。これにより被覆部材１は、コストを抑制することができる。 Since the covering member 1 can be wound around the pillar 7 at the time of measurement and easily removed after the measurement, it is excellent in portability and is suitable for the measurement of the pillar 7 which is arranged in various places. .. Further, since the covering member 1 has elasticity, it can be applied even if there is a difference between the diameter of the pillar 7 and the diameter of the through hole 3. As a result, the cost of the covering member 1 can be suppressed.

（第１の変形例）
図３を参照して第１の変形例に係る被覆部材を説明する。 (First modification)
The covering member according to the first modification will be described with reference to FIG.

図３（ａ）に示す被覆部材１１において、貫通穴１３から被覆部１２の端部までの第１の方向の距離は、第１の方向に直交する第２の方向の貫通穴１３から被覆部１２の端部までの距離よりも長くなるように形成される。「貫通穴１３から被覆部１２の端部までの第１の方向の距離」は、貫通穴１３と、被覆部１２の開口１４が設けられる辺に対向する辺の端部までの、距離であることが好ましい。測定装置９が照射するレーザー光の光軸に対して、被覆部１２の貫通穴１３よりも手前側（測定装置９側）は、脇側よりも広く形成される。 In the covering member 11 shown in FIG. 3A, the distance from the through hole 13 to the end of the covering portion 12 in the first direction is the distance from the through hole 13 in the second direction orthogonal to the first direction to the covering portion. It is formed so as to be longer than the distance to the end of 12. The "distance in the first direction from the through hole 13 to the end of the covering portion 12" is the distance between the through hole 13 and the end of the side facing the side where the opening 14 of the covering portion 12 is provided. Is preferable. The front side (measurement device 9 side) of the covering portion 12 with respect to the optical axis of the laser beam emitted by the measuring device 9 is formed wider than the side side.

図３（ａ）に示すように、貫通穴１３から被覆部１２の端までの、測定装置９側のＹ軸方向の最短の距離Ｌ１は、貫通穴１３から被覆部１２の端までのＸ軸方向の最短の距離Ｌ２よりも長い。測定装置９が照射する光軸を通るＹＺ平面において、貫通穴１３よりも測定装置９側の貫通穴１３から被覆部１２の端までの距離は、光軸と直交するＸＺ平面上の貫通穴１３から被覆部１２の端までの距離よりも長い。なお測定装置９は、図３（ａ）の紙面の下側に設置される。 As shown in FIG. 3A, the shortest distance L1 in the Y-axis direction on the measuring device 9 side from the through hole 13 to the end of the covering portion 12 is the X axis from the through hole 13 to the end of the covering portion 12. It is longer than the shortest distance L2 in the direction. In the YZ plane passing through the optical axis irradiated by the measuring device 9, the distance from the through hole 13 on the measuring device 9 side of the through hole 13 to the end of the covering portion 12 is the through hole 13 on the XZ plane orthogonal to the optical axis. It is longer than the distance from to the edge of the covering portion 12. The measuring device 9 is installed on the lower side of the paper surface of FIG. 3 (a).

このように、第１の変形例に係る被覆部材１１は、Ｙ軸方向の測定装置９側に広い面積を有するので、広い範囲で障害物８を押さえることができる。 As described above, since the covering member 11 according to the first modification has a large area on the measuring device 9 side in the Y-axis direction, the obstacle 8 can be pressed in a wide range.

図３（ａ）に示すように、第１の変形例に係る被覆部材１において貫通穴１３は略Ｕ形状を有し、開口１４が、柱体７の幅よりも広くなるように形成されるのが好ましい。柱体７の幅は、柱体７の長さ方向に直交する断面の幅であり、図２におけるＸ軸方向の長さである。図３（ａ）に示す例において開口１４は、貫通穴１３の最大幅と同じ幅を有する。 As shown in FIG. 3A, in the covering member 1 according to the first modification, the through hole 13 has a substantially U shape, and the opening 14 is formed so as to be wider than the width of the pillar 7. Is preferable. The width of the pillar 7 is the width of the cross section orthogonal to the length direction of the pillar 7, and is the length in the X-axis direction in FIG. In the example shown in FIG. 3A, the opening 14 has the same width as the maximum width of the through hole 13.

なお、開口１４の幅は、柱体７の幅と同じか、差分が小さい方が好ましい。柱体７の幅よりも広すぎる場合、柱体７と被覆部１２との間に隙間が生じ、障害物８を押さえきれない場合があるからである。 It is preferable that the width of the opening 14 is the same as the width of the pillar 7 or the difference is small. This is because if the width of the pillar 7 is too wide, a gap may be formed between the pillar 7 and the covering portion 12, and the obstacle 8 may not be completely suppressed.

第１の変形例において被覆部１２は、開口１４が設けられる辺と対向する辺と、貫通穴１３との距離が長いので、開口１４が小さい場合、被覆部材１が弾性を有していたとしても、開口１４を介して貫通穴１３に、柱体７を通すことができない場合がある。そこで、開口１４が、柱体７の幅よりも広く形成されることにより、柱体７は、貫通穴１３に容易に差し込むことができる。図３（ａ）のように開口１４が、柱体７の幅よりも広く形成される場合、被覆部１２の端部を捻る必要がないので、被覆部１２は、ゴム、織物以外にも、金属、鉱物等で形成されてもよく、弾性の有無は問わない。 In the first modification, the covering portion 12 has a long distance between the side facing the side on which the opening 14 is provided and the through hole 13, so that when the opening 14 is small, the covering member 1 has elasticity. However, there are cases where the pillar 7 cannot be passed through the through hole 13 through the opening 14. Therefore, since the opening 14 is formed wider than the width of the pillar 7, the pillar 7 can be easily inserted into the through hole 13. When the opening 14 is formed wider than the width of the pillar 7 as shown in FIG. 3A, it is not necessary to twist the end portion of the covering portion 12, so that the covering portion 12 can be used in addition to rubber and woven fabric. It may be made of metal, mineral, etc., and may or may not be elastic.

また図３（ｂ）に示すように被覆部材１１ａは、開口１４ａを挟む被覆部１２ａの一対の端部１２１ａおよび１２２ａを連結する開口連結部１５ａを備えても良い。開口連結部１５ａは、開口１４ａを挟む一対の端部１２１ａおよび１２２ａに、非伸縮性ないし難伸縮性のテープ部材を渡してテープ部材を固定し、一対の端部１２１ａおよび１２２ａとの間が所定幅以上開かないように規制する。 Further, as shown in FIG. 3B, the covering member 11a may include an opening connecting portion 15a for connecting a pair of ends 121a and 122a of the covering portion 12a sandwiching the opening 14a. In the opening connecting portion 15a, a non-stretchable or non-stretchable tape member is passed to a pair of ends 121a and 122a sandwiching the opening 14a to fix the tape member, and a predetermined space between the pair of ends 121a and 122a is formed. Regulate not to open more than the width.

図３（ｂ）において開口連結部１５ａは、テープ部材として、表面と裏面がそれぞれオスとメスに形成される面ファスナーを用いる。端部１２１ａに固定されたテープ部材を、端部１２２ａに固定された通し穴に通して、面ファスナーのオスとメスを貼り付ける。これにより、一対の端部１２１ａおよび１２２ａの距離を、所定値以上に広がらないように規制することができる。なお図３（ｂ）に示す開口連結部１５ａは一例であって、一対の端部１２１ａおよび１２２ａの距離が所定幅以上に広がらないように規制できれば、どのような機構を用いても良い。 In FIG. 3B, the opening connecting portion 15a uses a hook-and-loop fastener whose front surface and back surface are formed on male and female, respectively, as a tape member. The tape member fixed to the end portion 121a is passed through the through hole fixed to the end portion 122a, and the male and female surface fasteners are attached. Thereby, the distance between the pair of end portions 121a and 122a can be regulated so as not to be wider than a predetermined value. The opening connecting portion 15a shown in FIG. 3B is an example, and any mechanism may be used as long as the distance between the pair of end portions 121a and 122a can be regulated so as not to be wider than a predetermined width.

例えば、開口１４ａが柱体７の幅よりも狭い場合でも、被覆部１２ａが弾性を有する場合、柱体７によって被覆部１２ａがたわみ、柱体７の幅にあわせて貫通穴１３ａを広く形成することが可能である。この場合、端部１２１ａおよび１２２ａは、被覆部材１１ａの平置き状態時よりも広がるので、被覆部１２ａと柱体７との間に隙間が生じやすく、障害物８が押さえにくい場合がある。 For example, even if the opening 14a is narrower than the width of the pillar 7, if the covering portion 12a has elasticity, the covering portion 12a is bent by the pillar 7 to form a wide through hole 13a according to the width of the pillar 7. It is possible. In this case, since the ends 121a and 122a are wider than when the covering member 11a is placed flat, a gap is likely to be formed between the covering portion 12a and the pillar 7, and the obstacle 8 may be difficult to hold.

そこで、図３（ｂ）に示すように、端部１２１ａおよび１２２ａの距離をつめて開口連結部１５ａで連結する。被覆部１２ａと柱体７を近づけ、被覆部１２ａと柱体７との間に隙間を抑制することが可能になる。 Therefore, as shown in FIG. 3B, the ends 121a and 122a are closely connected by the opening connecting portion 15a. It is possible to bring the covering portion 12a and the pillar 7 closer to each other and suppress a gap between the covering portion 12a and the pillar 7.

なお、図３（ｂ）は、開口４が、柱体７の幅よりも広く形成される被覆部材１１ａに、開口連結部１５ａを設ける場合を説明したが、そのほかの実施例に開示される各開口に対して開口連結部を設けても良い。 In addition, although FIG. 3B has described the case where the opening connecting portion 15a is provided in the covering member 11a in which the opening 4 is formed wider than the width of the pillar 7, each disclosed in other examples. An opening connecting portion may be provided for the opening.

また被覆部の手前側を広く形成した場合でも、被覆部の弾性等によっては、図３（ｃ）のように被覆部材１１ｂを形成しても良い。被覆部材１１ｂの開口１４ｂを挟む端部１２１ｂおよび１２２ｂの距離は、図１に示す例よりも広く、図３（ａ）に示す例よりも狭い。端部１２１ｂおよび１２２ｂの距離は、図１よりも広く形成されることにより、開口１４ｂを介して貫通穴１３ｂに柱体７を通しやすい。また端部１２１ｂおよび１２２ｂの距離は、図３（ａ）よりも狭く形成されることにより、柱体７と被覆部１２ｂとの隙間を小さくし、より広い面積に生じた障害物８を押さえることが可能になる。端部１２１ｂおよび１２２ｂの距離は、被覆部１２ｂの弾性、開口連結部の有無等の被覆部材１１ｂの形状等に応じて適宜定められれば良い。 Further, even when the front side of the covering portion is formed widely, the covering member 11b may be formed as shown in FIG. 3C depending on the elasticity of the covering portion and the like. The distance between the ends 121b and 122b sandwiching the opening 14b of the covering member 11b is wider than the example shown in FIG. 1 and narrower than the example shown in FIG. 3A. Since the distances between the ends 121b and 122b are formed wider than in FIG. 1, it is easy to pass the pillar 7 through the through hole 13b through the opening 14b. Further, the distance between the end portions 121b and 122b is formed to be narrower than that in FIG. 3A, so that the gap between the pillar 7 and the covering portion 12b is reduced, and the obstacle 8 generated in a wider area is suppressed. Becomes possible. The distance between the end portions 121b and 122b may be appropriately determined according to the shape of the covering member 11b such as the elasticity of the covering portion 12b and the presence / absence of the opening connecting portion.

（第２の変形例）
本発明の実施の形態および第１の変形例において、被覆部が一体に形成される場合を説明したが、第２の変形例において被覆部が複数の部材で形成される場合を説明する。 (Second modification)
In the embodiment of the present invention and the first modification, the case where the covering portion is integrally formed has been described, but in the second modification, the case where the covering portion is formed by a plurality of members will be described.

図４（ａ）に示すように第２の変形例に係る被覆部材２１は、自重により設置面の障害物８を押さえる複数の被覆部２２により形成される。第２の変形例において被覆部２２は、Ｘ軸方向に二分する一対の被覆部２２である場合を説明するが、Ｙ軸方向に二分しても良いし、そのほかの軸を二分しても良い。また第２の変形例において被覆部２２は、２つの部材以上で形成されればよく、その数は問わない。 As shown in FIG. 4A, the covering member 21 according to the second modification is formed by a plurality of covering portions 22 that hold down the obstacle 8 on the installation surface by its own weight. In the second modification, the case where the covering portion 22 is a pair of covering portions 22 that are divided in the X-axis direction will be described, but the covering portion 22 may be divided in the Y-axis direction or the other axes may be divided in two. .. Further, in the second modification, the covering portion 22 may be formed of two or more members, and the number thereof does not matter.

一対の被覆部２２は、略Ｕ字形状に形成され、それぞれ凹部を有する。凹部が隣接することにより、柱体７の長さ方向の一部を収容する貫通穴２３が形成される。図４（ａ）に示す例において各被覆部２２は、それぞれ貫通穴３を形成する半円状の凹部を有する。凹部を隣接するように一対の被覆部２２を配設することにより、図４（ａ）に示すように、被覆部材２１に貫通穴２３を形成することができる。 The pair of covering portions 22 are formed in a substantially U shape, and each has a recess. By adjoining the recesses, a through hole 23 that accommodates a part of the pillar 7 in the length direction is formed. In the example shown in FIG. 4A, each covering portion 22 has a semicircular recess forming a through hole 3. By arranging the pair of covering portions 22 so that the recesses are adjacent to each other, the through hole 23 can be formed in the covering member 21 as shown in FIG. 4A.

柱体７を一対の被覆部２２のそれぞれで挟み込むことにより、図１に示す開口４がなくても、貫通穴２３に柱体７を通すことが可能になる。また貫通穴２３から被覆部２２の端までの距離が長く形成される場合でも、或いは被覆部２２が弾性を有さない場合でも、容易に、貫通穴２３に柱体７を通すことが可能になる。また貫通穴２３から被覆部２２の端までの距離が長く形成されない場合でも、また被覆部２２が弾性を有する場合でも、図４（ａ）に示すように、複数の被覆部２２により被覆部材２１が形成されても良い。 By sandwiching the pillar 7 between each of the pair of covering portions 22, the pillar 7 can be passed through the through hole 23 without the opening 4 shown in FIG. Further, even when the distance from the through hole 23 to the end of the covering portion 22 is formed to be long, or even when the covering portion 22 does not have elasticity, the pillar 7 can be easily passed through the through hole 23. Become. Further, even when the distance from the through hole 23 to the end of the covering portion 22 is not long, or when the covering portion 22 has elasticity, as shown in FIG. 4A, the covering member 21 is formed by the plurality of covering portions 22. May be formed.

また一対の被覆部２２も、隣接するように配設される。一対の被覆部２２によって設置面を覆い、一対の被覆部２２の隙間から障害物８が生じるのを回避することができる。 Further, the pair of covering portions 22 are also arranged so as to be adjacent to each other. It is possible to cover the installation surface with the pair of covering portions 22 and prevent the obstacle 8 from being generated from the gap between the pair of covering portions 22.

被覆部材２１は、図４（ａ）に示すように、複数の被覆部２２を接続する接続部を備えるのが好ましい。これにより、被覆部材２１を柱体７の設置面に安定的に配置することが可能になる。 As shown in FIG. 4A, the covering member 21 preferably includes a connecting portion for connecting a plurality of covering portions 22. This makes it possible to stably arrange the covering member 21 on the installation surface of the pillar 7.

図４（ａ）に示す例は、接続部が、Ｙ軸方向の手前側（測定装置９側）の蝶番２６と、Ｙ軸方向の奥側のパチン錠２７により形成される場合を示す。蝶番２６は、一対の被覆部２２の側面に固定的に接続され、蝶番２６を支点として、一対の被覆部２２のそれぞれが弧を描くように動いて、開いたり閉じたりすることが可能である。パチン錠２７は、一対の被覆部２２が隣接する際に、一対の被覆部２２を隣接した状態で固定することができる。一対の被覆部２２を開いた状態で柱体７を囲った後、一対の被覆部２２を閉じ合わせ、パチン錠２７で固定する。 The example shown in FIG. 4A shows a case where the connecting portion is formed by a hinge 26 on the front side (measurement device 9 side) in the Y-axis direction and a snap lock 27 on the back side in the Y-axis direction. The hinge 26 is fixedly connected to the side surface of the pair of covering portions 22, and each of the pair of covering portions 22 moves in an arc with the hinge 26 as a fulcrum, and can be opened and closed. .. The snap lock 27 can fix the pair of covering portions 22 in an adjacent state when the pair of covering portions 22 are adjacent to each other. After surrounding the pillar 7 with the pair of covering portions 22 open, the pair of covering portions 22 are closed and fixed with a snap lock 27.

図４（ａ）に示す接続部の例は、一例であって、これに限るものではない。例えば、蝶番２６とパチン錠２７を、逆に配設しても良い。また、一対の被覆部２２の手前と奥側の両方にパチン錠を配設し、一対の被覆部２２を分離した状態から、パチン錠で一対の被覆部２２を閉じ合わせて固定しても良い。一対の被覆部２２を離したり接続したり可能な部材であれば、パチン錠に限らず、どのような機構が用いられても良い。 The example of the connection portion shown in FIG. 4A is an example and is not limited to this. For example, the hinge 26 and the snap lock 27 may be arranged in reverse. Further, a snap lock may be arranged on both the front side and the back side of the pair of covering portions 22, and the pair of covering portions 22 may be closed and fixed with the snap lock from the state where the pair of covering portions 22 are separated. .. Any mechanism may be used, not limited to a snap lock, as long as the pair of covering portions 22 can be separated or connected to each other.

なお、図４（ａ）に示す例において、貫通穴２３は切れ目のない円を形成し、開口が設けられていないが、被覆部が複数部材で形成される場合でも、図４（ｂ）に示すように、開口２４ａが設けられても良い。 In the example shown in FIG. 4A, the through hole 23 forms a continuous circle and is not provided with an opening, but even when the covering portion is formed of a plurality of members, FIG. 4B shows. As shown, the opening 24a may be provided.

図４（ｂ）に示す被覆部材２１ａは、略Ｌ字形状の一対の被覆部２２により形成され、開口２４ａが広く形成され、Ｕ形状の貫通穴２３ａが形成される。また被覆部材２１ａには、図３（ｂ）で説明したような開口連結部２５ａが設けられる。蝶番２６ａにより一対の被覆部２２ａが開くことが可能な場合でも、開口連結部２５ａにより一対の被覆部２２ａが所定の距離以上に開くのを回避することができる。 The covering member 21a shown in FIG. 4B is formed by a pair of substantially L-shaped covering portions 22, the opening 24a is formed widely, and the U-shaped through hole 23a is formed. Further, the covering member 21a is provided with an opening connecting portion 25a as described with reference to FIG. 3B. Even when the pair of covering portions 22a can be opened by the hinge 26a, it is possible to prevent the pair of covering portions 22a from opening more than a predetermined distance by the opening connecting portion 25a.

（第３の変形例）
第３の変形例では、被覆部と柱体７の隙間を埋める緩衝部材が用いられる場合を説明する。 (Third variant)
In the third modification, a case where a cushioning member for filling the gap between the covering portion and the pillar 7 is used will be described.

図５（ａ）に示す被覆部材３１は、被覆部３２の貫通穴３３に接する部分に、貫通穴３３の中心方向（半径方向）に伸縮する緩衝部材３７が設けられる。緩衝部材３７は、スポンジ、ウレタン、ゴムなどの伸縮性を有する部材で形成される。緩衝部材３７は、柱体７を囲う円形状を有するが、開口３４に対応する部分は、柱体７を通すために途切れている。 The covering member 31 shown in FIG. 5A is provided with a cushioning member 37 that expands and contracts in the central direction (radial direction) of the through hole 33 at a portion of the covering portion 32 in contact with the through hole 33. The cushioning member 37 is formed of a stretchable member such as sponge, urethane, or rubber. The cushioning member 37 has a circular shape surrounding the pillar 7, but the portion corresponding to the opening 34 is interrupted for passing the pillar 7.

被覆部３２と柱体７との間に隙間ができた場合でも、緩衝部材３７が伸縮して隙間を埋め、障害物８を押さえることが可能になる。また緩衝部材３７は、貫通穴３３の中心方向に伸縮しやすいのに対し、Ｚ軸方向においては、中心方向よりも伸縮しにくいことが好ましい。このような緩衝部材３７は、障害物８をより適切に押さえることが可能である。 Even if a gap is formed between the covering portion 32 and the pillar body 7, the cushioning member 37 expands and contracts to fill the gap, and the obstacle 8 can be suppressed. Further, while the cushioning member 37 easily expands and contracts in the central direction of the through hole 33, it is preferable that the cushioning member 37 expands and contracts less in the Z-axis direction than in the central direction. Such a cushioning member 37 can more appropriately hold down the obstacle 8.

図５（ａ）に示す緩衝部材３７は、図１ないし図４を参照して説明した各被覆部材に適用することができる。 The cushioning member 37 shown in FIG. 5A can be applied to each covering member described with reference to FIGS. 1 to 4.

図５（ｂ）に示す被覆部材３１ａは、図３（ａ）を参照して説明した被覆部材１１の被覆部１２に、緩衝部材３７ａを配設したものである。開口３４ａは、貫通穴３の最大幅と同じを有する一方、緩衝部材３７ａは、柱体７の周方向に広く覆うように形成される。緩衝部材３７は、Ｙ軸方向の手前側で被覆部３２ａに沿い、奥側で、被覆部３２ａから離れて、弧を描くように配設される。これにより、柱体７の奥側の障害物８も緩衝部材３７ａで押さえることができる。 The covering member 31a shown in FIG. 5B is formed by disposing a cushioning member 37a on the covering portion 12 of the covering member 11 described with reference to FIG. 3A. The opening 34a has the same maximum width as the through hole 3, while the cushioning member 37a is formed so as to widely cover the column 7 in the circumferential direction. The cushioning member 37 is arranged so as to draw an arc along the covering portion 32a on the front side in the Y-axis direction and away from the covering portion 32a on the back side. As a result, the obstacle 8 on the back side of the pillar 7 can also be pressed by the cushioning member 37a.

緩衝部材３７ａの奥側の被覆部３２ａから離れる部分において、緩衝部材３７ａが柱体７に沿いやすいように、緩衝部材３７ａの背面（柱体７と接する面と対向する面）に、金属シート等の変形しづらい部材が貼付されても良い。 A metal sheet or the like is placed on the back surface of the cushioning member 37a (the surface facing the surface in contact with the pillar 7) so that the cushioning member 37a can easily follow the pillar 7 at a portion away from the covering portion 32a on the inner side of the cushioning member 37a. A member that is hard to be deformed may be attached.

図６（ａ）に示す被覆部材３１ｂは、図４（ａ）を参照して説明した被覆部材２１の一対の被覆部２２に、それぞれ一対の緩衝部材３７ｂを配設したものである。一対の被覆部３２ｂのそれぞれの凹部（貫通穴３３ｂと接する部分）に、一対の緩衝部材３７ｂが配設される。一対の緩衝部材３７ｂは、互いに隣接するように配設される。貫通穴３３ｂの外周と同様の円形状が形成され、柱体７と被覆部３２ｂとの間を、一対の緩衝部材２７ｂで埋めることが可能である。 The covering member 31b shown in FIG. 6A is formed by arranging a pair of cushioning members 37b on a pair of covering portions 22 of the covering member 21 described with reference to FIG. 4A. A pair of cushioning members 37b are arranged in each recess (a portion in contact with the through hole 33b) of the pair of covering portions 32b. The pair of cushioning members 37b are arranged so as to be adjacent to each other. A circular shape similar to the outer circumference of the through hole 33b is formed, and the space between the pillar 7 and the covering portion 32b can be filled with a pair of cushioning members 27b.

図６（ｂ）に示す被覆部材３１ｃは、図４（ｂ）を参照して説明した被覆部材２１ａの一対の被覆部２２ａに、緩衝部材３７ｃを配設したものである。緩衝部材３７ｃは、図５（ｂ）を参照して説明した緩衝部材３７ａと同様である。 The covering member 31c shown in FIG. 6B is formed by disposing a cushioning member 37c on a pair of covering portions 22a of the covering member 21a described with reference to FIG. 4B. The cushioning member 37c is the same as the cushioning member 37a described with reference to FIG. 5 (b).

（第４の変形例）
第４の変形例は、折りたたみ可能な被覆部材を説明する。 (Fourth modification)
A fourth modification describes a foldable covering member.

図７（ａ）に示す被覆部材４１は、図３（ａ）に示す被覆部材１１を折りたたみ可能に形成したものである。被覆部材４１の被覆部４２は、奥側が別部材で形成され、蝶番４９により、貫通穴４３側に折りたたむことが可能である。これにより、被覆部材４１の可搬性を向上させることができる。また被覆部４２の奥側は細く形成されるので、運搬時に破損が生じやすいところ、蝶番４９により折りたたみ可能であるので、運搬時の破損を回避することができる。 The covering member 41 shown in FIG. 7A is a foldable covering member 11 shown in FIG. 3A. The back side of the covering portion 42 of the covering member 41 is formed of a separate member, and the covering portion 42 can be folded toward the through hole 43 side by the hinge 49. Thereby, the portability of the covering member 41 can be improved. Further, since the inner side of the covering portion 42 is formed thinly, it is liable to be damaged during transportation, but it can be folded by the hinge 49, so that damage during transportation can be avoided.

図７（ｂ）に示す被覆部材４１ａは、図７（ａ）と同様に、被覆部４２ａの奥側を折りたたみ可能に形成したものである。図７（ａ）は、一体に形成される被覆部４２を備える被覆部材４１を開示するのに対し、図７（ｂ）は、一対の被覆部４２ａが蝶番４６ａにより接続する被覆部材４１ａを開示する点で異なる。 Similar to FIG. 7A, the covering member 41a shown in FIG. 7B is formed so that the back side of the covering portion 42a can be folded. FIG. 7A discloses a covering member 41 including a covering portion 42 integrally formed, whereas FIG. 7B discloses a covering member 41a in which a pair of covering portions 42a are connected by a hinge 46a. It differs in that it does.

（第５の変形例）
第５の変形例は、本発明の実施の形態および第１ないし第４の変形例で説明した被覆部材を用いて測定装置９で測定する際に、柱体７の端の視認性を向上させる測定支援システムを説明する。 (Fifth variant)
The fifth modification improves the visibility of the end of the column 7 when the measuring device 9 measures using the covering member described in the embodiment of the present invention and the first to fourth modifications. The measurement support system will be described.

図８に示すように、柱体７の面に、背景部材６が配設される。背景部材６は、柱体７の幅よりも大きく、柱体７の脇の視認性を向上させる色を有する。 As shown in FIG. 8, the background member 6 is arranged on the surface of the pillar 7. The background member 6 is larger than the width of the pillar 7 and has a color that improves the visibility of the side of the pillar 7.

図８に示すように、測定装置９の光軸の柱体７より奥側に、背景部材６が立てかけられる。この背景部材６は、測定装置９から柱体７を観察した際の背景となる。貫通穴３に柱体７を収容するように被覆部材１を配設した後、背景部材６を柱体７の奥側（測定装置９の光軸上の柱体７の先）に配設して、柱体７の手前側から測定装置９で柱体７を測定する。これにより、柱体７の脇を特定しやすくなるので、設置面近傍の柱体７の脇を基準マークに、容易に一致させることができる。 As shown in FIG. 8, the background member 6 is leaned against the back side of the pillar 7 of the optical axis of the measuring device 9. The background member 6 serves as a background when the pillar 7 is observed from the measuring device 9. After arranging the covering member 1 so as to accommodate the column 7 in the through hole 3, the background member 6 is arranged on the back side of the column 7 (the tip of the column 7 on the optical axis of the measuring device 9). Then, the pillar 7 is measured by the measuring device 9 from the front side of the pillar 7. This makes it easier to identify the side of the pillar 7, so that the side of the pillar 7 near the installation surface can be easily matched with the reference mark.

背景部材６の柱体７に接する面の色は、柱体７の色と区別のつきやすい色を有する。例えば柱体７の色が、白または薄いグレーなど、色相がなく明度が高い場合、背景部材６は、黒または濃いグレーなどの色相がなく明度が低い色となる。逆に、柱体７の色が、黒または濃いグレーなど、色相がなく明度が低い場合、背景部材６は、白または薄いグレーなどの色相がなく明度が低い色となる。また柱体７の色に色相がある場合、背景部材６は、柱体の色の補色となる。 The color of the surface of the background member 6 in contact with the pillar 7 has a color that is easily distinguishable from the color of the pillar 7. For example, when the color of the pillar 7 has no hue and high brightness such as white or light gray, the background member 6 has no hue such as black or dark gray and has low brightness. On the contrary, when the color of the pillar 7 has no hue such as black or dark gray and the brightness is low, the background member 6 has no hue such as white or light gray and has a low brightness. When the color of the pillar 7 has a hue, the background member 6 is a complementary color to the color of the pillar 7.

背景部材６の高さ（Ｚ軸方向の長さ）は、柱体７周辺の障害物８の高さ、或いは煩雑な背景の範囲等によって、適宜定められる。ここで障害物８は、雑草のみならず、被覆部材１で押すことが困難な植え込み、花壇等も含む。 The height of the background member 6 (length in the Z-axis direction) is appropriately determined depending on the height of the obstacle 8 around the pillar 7, the complicated background range, and the like. Here, the obstacle 8 includes not only weeds but also plantings, flower beds and the like that are difficult to push with the covering member 1.

背景部材６は、ゴムまたはウレタン等の自立可能で、巻いて収容可能な程度の剛性を有するシート状部材であるのが好ましい。自立できることにより、背景部材６以外の部材も用いずに測定することができ、巻いて収納できることにより、可搬性に優れ、各地に配設される柱体７の測定に適する。また他の実施例として背景部材６は、板状部材であっても良いし、枠を用いて柱体７の背後に配設するシート状部材であっても良い。 The background member 6 is preferably a sheet-like member such as rubber or urethane that can stand on its own and has rigidity enough to be rolled and accommodated. Since it can stand on its own, it can be measured without using a member other than the background member 6, and since it can be rolled up and stored, it has excellent portability and is suitable for measuring pillars 7 arranged in various places. Further, as another embodiment, the background member 6 may be a plate-shaped member or a sheet-shaped member arranged behind the pillar 7 using a frame.
