【０００９】
請求項４は、請求項１〜３の何れかに記載の支柱固定台において、各分割台２は鋳鉄鋳物からなることを特徴とする。
【００１０】
【発明の実施の形態】
図１の（Ａ）はソーラー式バス停標識１０の支柱１２を固定する本発明の支柱固定台１を示す正面図、（Ｂ）は（Ａ）に示す支柱固定台１を９０°回転した状態での側面図であり、図２は支柱固定台１の拡大縦断面図、図３は図２に示す支柱固定台１の底面図である。これらの図面に示されるように、支柱固定台１は、支柱１２を取り囲むように周方向に９０°で四分割して夫々平面視略扇形に形成された四個の分割台２…を周方向に組み合わせて、隣合う分割台２，２同士をボルト３結合し、これら４個の分割台２…を上下複数段（ここでは３段）に重ね合わせることによって構成されるものである。このバス停標識１０は、支柱１２によって支えられる標識本体部２２を有し、この標識本体部２２の上部に太陽電池２３が装備されている。
【００１１】
各分割台２は、上記のように平面視略扇形に形成された鋳鉄鋳物からなるもので、その構造を図４〜図８に示す。これらの図面から分かるように、各分割台２には、バス停標識１０の支柱１２の下端部外周面に嵌合する嵌合凹部４と、周方向に隣合う分割台２，２同士をボルト３結合するためのボルト挿通孔５とが設けられている。各分割台２の外周面２ａにはその両端部にボルト挿入用の凹溝部６が設けられていて、各凹溝部６の一端側に、上記ボルト挿通孔５が分割台２の端面２ｂと直交するように貫設されている（図７参照）。
【００１２】
また図４〜図８に示すように、各分割台２の上面側には、外周面２ａに沿ってテーパ面部７ａを有する嵌合凸段部７が形成され、各分割台２の下面側には、前記嵌合凸段部７のテーパ面部７ａに対応するテーパ面部８ａを有して、前記嵌合凸段部７が嵌合可能な嵌合凹段部８が形成されている。
【００１３】
次に、上記のような構成の分割台２を所要数個組み合わせて、図１に示すようなバス停標識１０の支柱１２を固定する支柱固定台１を組み立てる方法について説明する。
【００１４】
支柱固定台１の組み立てに先立って、図２及び図３に示すように、バス停標識１０の支柱１２の下端に正方形の金属製の接地プレート１３を溶接によって固着すると共に、この接地プレート１３の上面周辺部に金属製の台枠片１４を同様に溶接して固着しておく。
【００１５】
先ず、バス停標識１０の支柱１２を、その接地プレート１３を介して所定の設置場所に接地した状態で、支柱１２の下端部を取り囲むように４個の分割台２…を配置して、各分割台２の嵌合凹部４が支柱１２下端部の外周面に嵌合すると共に各分割台２の端面２ｂ同士が当接するよう周方向に組み合わせる。しかして、隣合う分割台２，２の隣接するボルト挿通孔５，５にボルト３を挿通し、各ボルト３にナット１１を螺合して締め付けることにより、４個の分割台２…を一体に組み付けると共に、４個の分割台２…の嵌合凹部４…によって支柱１２の下端部外周面を掴持する。この時、接地プレート１３上に固着されている台枠片１４が４個の分割台２…で押さえ付けられた状態となる（図２参照）。
【００１６】
尚、隣合う分割台２，２同士をボルト３結合する際には、両分割台２，２の隣接するボルト挿通孔５，５にボルト３を挿通することによって、そのボルト３が両分割台２，２の隣接するボルト挿入用凹溝部６，６に埋没されてしまい、各分割台２の外周面２ａから突出することがないから、外観上の体裁が良く、また外周面２ａに障害物となる突起部がないため、使用上安全となる。
【００１７】
こうして一段目の４個の分割台２…の組み付けを終えたならば、この一段目分割台２…上に夫々分割台２の重ね合わせる。この際、下段側分割台２の上面側に形成された嵌合凸段部７に、上段側分割台２の下面側に形成された嵌合凹段部８を嵌合させるようにするから、重ね合わせ作業が簡単容易に行うことができる。一段目分割台２…の上に二段目分割台２…を夫々重ね合わせたならば、前記同様にして隣合う分割台２，２の隣接するボルト挿通孔５，５にボルト３を挿通し、ナット１１を螺合して締め付けることによって、二段目４個の分割台２…を一体的に組み付けると共にこれら分割台２…の嵌合凹部４…によって支柱１２の下端部外周面を掴持する。
【００１８】
二段目の４個の分割台２…の組み付けを終えた後、上記同様な要領で三段目の４個の分割台２…の組み付けを行って、図２、図９〜図１１に示すように各段４個の分割台２…が上下三段に重ね合わさった支柱固定台１を形成する。この時、支柱１２の下端部外周面が三段１２個の分割台２…によって掴持されると共に、これら分割台２…の荷重が台枠片１４を介して接地プレート１３の上にかけられるから、支柱１２は地面に対し垂直状態に確実に固定保持される。図９は、バス停標識１０の支柱１２を省略した状態での三段重ね支柱固定台１の平面図、図１０は同支柱固定台１の側面図、図１１は同支柱固定台１の底面図である。
【００１９】
上記のようにして形成される支柱固定台１は、夫々鋳鉄鋳物からなる各段４個で上下三段の合計１２個の分割台２…によって分割構成されるもので、バス停標識１０の設置現場で組み立てられるようになっているから、図１２の（Ｂ）に示すような置き石タイプの固定台３１に比べ、現場までの運搬が非常に楽になる。また、このように分割構成される支柱固定台１であって、運搬が楽であるため、全体の重量を十分に大きくすることができ、それによりバス停標識１０が風や振動等で倒れたり、不心得者によってバス停標識１０の向きが変えられたり、持ち去られるようなことがなくなる。
【００２０】
また、現場での支柱固定台１の組み立てにあたっては、上述したように、支柱１２の下端部を取り囲むように４個の分割台２…を配置し、各分割台２の嵌合凹部４が支柱１２下端部の外周面に嵌合すると共に各分割台２の端面２ｂ同士が当接するよう周方向に組み合わせて、隣合う分割台２，２の隣接するボルト挿通孔５，５にボルト３を挿通し、ナット１１を螺合して締め付けることによって、一段目４個の分割台２…を組み付け、こうして一段目４個の分割台２…の組み付けを終えた後、一段目分割台２…上に夫々分割台２を重ね合わせ、二段目４個の分割台２…を組み付け、以降も同様にすればよいから、組み立て作業が非常に簡単且つ容易となる。
【００２１】
そして、各段４個の分割台２…を複数段に重ね合わせる際に、下段側分割台２の上面側に形成された嵌合凸段部７に、上段側分割台２の下面側に形成された嵌合凹段部８を嵌合させることによって、各分割台２の位置決めが行なえるから、重ね合わせ作業が簡単容易に行え、また、下段側分割台２の嵌合凸段部７に上段側分割台２の嵌合凹段部８が嵌合する際には、嵌合凹段部８に形成されているテーパ面部８ａが、嵌合凸段部７に形成されているテーパ面部７ａにテーパ嵌合するため、上下の分割台２，２同士が互いに強固に固定された状態となり、ガタついたり、ずれたりすることがなく、きわめて堅固な重ね合わせ状態となる。
【００２２】
以上の実施形態では、各段４個の分割台２…を上下複数段（ここでは３段）に重ね合わせて、支柱固定台１を形成する場合について説明したが、１段４個の分割台２…のみによって支柱固定台１を形成してもよい。また、各段の分割台２の個数は、４個に限らず、２個でもよいし、３個でもよく、また４個以上としてもよい。但し、分割台２は、周方向に一定角度で均等に分割形成されるものとし、そうすることによって１種類の分割台２の製作で済み、コストが安くつく。
【００２３】
また分割台２は、鋳鉄鋳物で作ることによって、重量が大きく、安定性がある上、製作費が安くなる。もちろん、分割台２は、鋳鉄鋳物に限るものではなく、コンクリートで形成してもよい。コンクリートの場合は、ボルト挿通孔５のボルト３及びナット１１が当たる部分に金具を取り付けるようにするとよい。
【００２４】
【発明の効果】
請求項１に係る発明の支柱固定台は、支柱を取り囲むように周方向に一定角度で分割形成された複数個の分割台からなり、各分割台に、支柱下端部の外周面に嵌合する嵌合凹部と、周方向に隣合う分割台同士をボルト結合するボルト挿通孔とを設け、これら複数個の分割台を周方向に組み合わせて隣合う分割台同士をボルト結合するようにしたものであるから、従来の置き石タイプの固定台に比べ、現場までの運搬が楽となると共に、重量を大きくできるため、標識が風や振動等で倒れたり、不心得者によって標識の向きが変えられたり、持ち去られるようなことがなく、しかも支柱固定台の組み立て作業が簡単容易に行える。
また本発明の支柱固定台によれば、隣合う分割台同士をボルト結合する際には、両分割台の隣接するボルト挿通孔にボルトを挿通することによって、そのボルトが両分割台の隣接するボルト挿入用凹溝部に埋没されてしまい、各分割台の外周面から突出することがないから、外観上の体裁が良く、また各分割台の外周面に障害物たる突起部が出ないため、使用上、安全となる。
【００２５】
請求項２に係る発明の支柱固定台は、複数個の分割台を周方向に組み合わせて隣合う分割台同士をボルト結合したものを、複数段に重ね合わせてなるものであるから、分割台の個数を多くすることができ、それにより重量を一層大きくできながら、運搬が楽となり、そして転倒防止、回転防止及び盗難防止の各作用が一層有効に働くことになる。
【００２６】
請求項３に係る発明の支柱固定台によれば、各分割台の上面側に、テーパ面部を有する嵌合凸段部を形成すると共に、各分割台の下面側に、前記嵌合凸段部のテーパ面部に対応するテーパ面部を有して、その嵌合凸段部が嵌合可能な嵌合凹段部を形成しているから、重ね合わせ作業が簡単容易に行え、また下段側分割台の嵌合凸段部に上段側分割台が嵌合する際には、嵌合凹段部に形成されているテーパ面部が、嵌合凸段部のテーパ面部にテーパ嵌合するため、上下の分割台同士が互いに強固に固定された状態となり、ガタついたり、ずれたりすることがなく、きわめて堅固な重ね合わせ状態となる。
【００２８】
請求項４に係る発明の支柱固定台によれば、分割台が鋳鉄鋳物からなるため、重量が大きく、安定性が良好になると共に、製作費を安くできる。

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1A is a front view showing the column fixing base 1 of the present invention for fixing the column 12 of the solar bus stop sign 10, and FIG. 1B is a state in which the column fixing base 1 shown in FIG. 2 is an enlarged longitudinal sectional view of the column fixing base 1, and FIG. 3 is a bottom view of the column fixing base 1 shown in FIG. As shown in these drawings, the column fixing base 1 is divided into four divided bases 2... Formed in a substantially fan shape in plan view by dividing into four at 90 ° in the circumferential direction so as to surround the column 12. In combination, the adjacent split bases 2 and 2 are connected to each other by bolts 3 and these four split bases 2 are overlapped in a plurality of upper and lower stages (here, three stages). The bus stop sign 10 has a sign body part 22 supported by a support column 12, and a solar cell 23 is mounted on the sign body part 22.
[0011]
Each dividing table 2 is made of a cast iron casting formed in a generally fan shape in plan view as described above, and the structure thereof is shown in FIGS. As can be seen from these drawings, each split base 2 has a fitting recess 4 that fits on the outer peripheral surface of the lower end of the column 12 of the bus stop sign 10 and the split bases 2 and 2 adjacent to each other in the circumferential direction are bolts 3. A bolt insertion hole 5 for coupling is provided. The outer peripheral surface 2a of each split table 2 is provided with concave groove portions 6 for inserting bolts at both ends thereof, and the bolt insertion holes 5 are orthogonal to the end surface 2b of the split table 2 at one end side of each concave groove portion 6. (See FIG. 7).
[0012]
Further, as shown in FIGS. 4 to 8, on the upper surface side of each divided table 2, a fitting convex portion 7 having a tapered surface portion 7 a along the outer peripheral surface 2 a is formed, and on the lower surface side of each divided table 2. Has a tapered surface portion 8a corresponding to the tapered surface portion 7a of the fitting convex step portion 7, and a fitting concave step portion 8 into which the fitting convex step portion 7 can be fitted is formed.
[0013]
Next, a method of assembling the column fixing base 1 for fixing the column 12 of the bus stop sign 10 as shown in FIG.
[0014]
Prior to the assembly of the column fixing base 1, as shown in FIGS. 2 and 3, a square metal ground plate 13 is fixed to the lower end of the column 12 of the bus stop sign 10 by welding, and the upper surface of the ground plate 13 is fixed. A metal frame piece 14 is similarly welded and fixed to the periphery.
[0015]
First, in a state where the support column 12 of the bus stop sign 10 is grounded to a predetermined installation location via the grounding plate 13, four division bases 2 are arranged so as to surround the lower end portion of the support column 12, and each division is performed. The fitting recesses 4 of the table 2 are fitted to the outer peripheral surface of the lower end portion of the support column 12 and are combined in the circumferential direction so that the end surfaces 2b of the divided tables 2 come into contact with each other. The bolts 3 are inserted into the adjacent bolt insertion holes 5 and 5 of the adjacent split bases 2 and 2, and the nuts 11 are screwed into the respective bolts 3 to be tightened, thereby integrating the four split bases 2. And the outer peripheral surface of the lower end portion of the support column 12 is held by the fitting recesses 4 of the four divided bases 2. At this time, the frame piece 14 fixed on the ground plate 13 is pressed by the four divided bases 2 (see FIG. 2).
[0016]
When the adjacent split bases 2 and 2 are connected to each other by the bolt 3, the bolt 3 is inserted into the adjacent bolt insertion holes 5 and 5 of the split bases 2 and 2, so that the bolt 3 is connected to the split bases. 2 and 2 are buried in the adjacent groove portions 6 and 6 for inserting bolts, and do not protrude from the outer peripheral surface 2a of each of the dividing bases 2, so that the appearance is good and the outer peripheral surface 2a has an obstacle. Since there is no protruding part, it is safe to use.
[0017]
When the assembly of the four first-stage division tables 2 is finished in this way, the division tables 2 are superposed on the first-stage division tables 2. At this time, because the fitting concave step portion 8 formed on the lower surface side of the upper stage side split table 2 is fitted to the fitting convex step portion 7 formed on the upper surface side of the lower stage side split table 2, Superposition work can be easily and easily performed. If the second stage split bases 2 are respectively superimposed on the first stage split bases 2 ..., the bolts 3 are inserted into the adjacent bolt insertion holes 5, 5 of the adjacent split bases 2, 2 in the same manner as described above. Then, the nut 11 is screwed and tightened, so that the four stages of the second stage 2 are integrally assembled, and the outer peripheral surface of the lower end of the column 12 is gripped by the fitting recesses 4 of these parts 2. To do.
[0018]
After finishing the assembly of the four stages of the second stage 2, the assembly of the four stages 2 of the third stage is performed in the same manner as described above, and shown in FIGS. 2 and 9 to 11. In this way, the column fixing base 1 is formed in which the four divided bases 2... At this time, the outer peripheral surface of the lower end portion of the support column 12 is held by the three stages 12 divided bases 2... And the load of the divided bases 2 is applied onto the ground plate 13 via the frame piece 14. The column 12 is securely fixed and held in a state perpendicular to the ground. FIG. 9 is a plan view of the three-stage stacked support base 1 with the support 12 of the bus stop sign 10 omitted, FIG. 10 is a side view of the support base 1, and FIG. 11 is a bottom view of the support base 1. It is.
[0019]
The column fixing base 1 formed as described above is divided into four stages each made of cast iron, and is divided into a total of twelve division bases 2 in three upper and lower stages. Therefore, it is very easy to transport to the site as compared with the stationary stone type fixing base 31 as shown in FIG. 12 (B). Moreover, since it is the support | pillar fixing stand 1 comprised in this way, and transportation is easy, the whole weight can be enlarged enough, and thereby the bus stop sign 10 may fall down by a wind, a vibration, etc., The direction of the bus stop sign 10 is not changed or taken away by unskilled persons.
[0020]
Further, when assembling the column fixing base 1 at the site, as described above, the four split bases 2 are arranged so as to surround the lower end portion of the post 12, and the fitting recesses 4 of the respective split bases 2 are arranged in the post. 12 are fitted to the outer peripheral surface of the lower end portion, and are combined in the circumferential direction so that the end surfaces 2b of the divided bases 2 are in contact with each other, and the bolts 3 are inserted into the adjacent bolt insertion holes 5, 5 of the adjacent divided bases 2, 2. Then, the nuts 11 are screwed and tightened to assemble the four first-stage divided bases 2..., And thus after the first stage four divided bases 2. Since each of the split bases 2 is overlapped and the second stage of the four split bases 2 are assembled and the same is performed thereafter, the assembling work becomes very simple and easy.
[0021]
Then, when the four divided blocks 2 in each stage are overlapped in a plurality of stages, they are formed on the lower surface side of the upper divided table 2 on the fitting convex step 7 formed on the upper surface side of the lower divided table 2. By fitting the fitted concave stepped portions 8, the respective divided bases 2 can be positioned, so that the superposition operation can be performed easily and easily. When the fitting concave step 8 of the upper split table 2 is fitted, the tapered surface portion 8a formed on the fitting concave step 8 is changed to the tapered surface portion 7a formed on the fitting convex step 7. Since the upper and lower divided bases 2 and 2 are firmly fixed to each other, the upper and lower divided bases 2 and 2 are in a state of being firmly fixed to each other.
[0022]
In the above embodiment, the case where the column fixing base 1 is formed by superimposing the upper and lower divided stages 2 (three stages in this case) on each of the four divided stages 2. The column fixing base 1 may be formed only by 2. Further, the number of the dividing tables 2 in each stage is not limited to four, but may be two, three, or four or more. However, the dividing table 2 is equally divided and formed at a constant angle in the circumferential direction. By doing so, one type of dividing table 2 can be manufactured, and the cost can be reduced.
[0023]
Further, by making the dividing table 2 from cast iron casting, the weight is large and stable, and the manufacturing cost is reduced. Of course, the dividing table 2 is not limited to cast iron casting, and may be formed of concrete. In the case of concrete, it is preferable to attach the metal fitting to the portion of the bolt insertion hole 5 where the bolt 3 and the nut 11 come into contact.
[0024]
【The invention's effect】
The column fixing base of the invention according to claim 1 is composed of a plurality of split bases that are divided and formed at a constant angle in the circumferential direction so as to surround the post, and is fitted to the outer peripheral surface of the lower end of the post. A fitting recess and a bolt insertion hole for bolting the divided bases adjacent in the circumferential direction are provided, and these divided bases are combined in the circumferential direction so that the adjacent divided bases are bolted together. Because it is easier to transport to the site and can be heavier than conventional stationary stone type fixed bases, the signs may fall down due to wind or vibration, etc. In addition, the column fixing base can be assembled easily and easily.
Moreover, according to the column fixing base of the present invention, when bolting adjacent split bases, the bolts are adjacent to both split bases by inserting bolts into adjacent bolt insertion holes of both split bases. Since it is buried in the concave groove for bolt insertion and does not protrude from the outer peripheral surface of each split table, the appearance is good, and since the projection part that is an obstacle does not appear on the outer peripheral surface of each split table, Safe to use.
