従来部材端に固定した半球状凹入部へ他の部材端へ固定した球体を嵌合させた自在継手が知られている。また、従来の手摺り等の接続部は、水平角度、垂直角度共に設計どおりに製作されており、これを現場で取付工事により固定するのみであって、現場の場所に応じて適宜切断して、固定する方式になっていない。   Conventionally, a universal joint is known in which a sphere fixed to the other member end is fitted into a hemispherical recessed portion fixed to the end of the member. Also, conventional handrails and other connecting parts are manufactured as designed for both horizontal and vertical angles, which are only fixed by installation work on site, and cut appropriately according to the site location. It is not a fixed method.

従って現場の取付構造の寸法が微妙に相違する場合には、現場調整不可能の場合もあった。また現場と、取付けるべき手摺り等の寸法（角度）相違によって、新しく出来てくるのを待ったり、多少の相違はあっても、そのまま（微調整なし）取付けることによって、出来上がり状態が若干外観を損するおそれもあった。   Therefore, when the size of the installation structure on site is slightly different, there are cases where the site adjustment is impossible. Also, depending on the difference in dimensions (angle) such as handrails to be installed on the site, even if there is a slight difference, there is a slight difference. There was also a risk of damage.

また接続端部の角度を水平方向又は垂直方向の調整可能にして、前記問題点を避けることも考えられるが、その多くは垂直角度のみ、又は水平角度のみ調節自在となっており、垂直方向及び水平方向共に調節できるようにはならない問題点があった。   In addition, it may be possible to adjust the angle of the connection end in the horizontal direction or the vertical direction to avoid the above-mentioned problem, but most of them are adjustable only in the vertical angle or only in the horizontal angle. There was a problem that it was not possible to adjust both in the horizontal direction.

然し乍ら、現場は千差万別であり、垂直方向又は水平方向の何れにおいても微小の調整があった方がより正確な取付けができる場合も少なくなかった。   However, there are many different sites, and there are many cases where more accurate mounting can be performed with fine adjustment in either the vertical direction or the horizontal direction.

また前記半球状凹入部へ球体を嵌合した自在継手は、位置の調節がむずかしい問題点があった。   In addition, the universal joint in which a sphere is fitted into the hemispherical recessed portion has a problem that it is difficult to adjust the position.

従来調整環の嵌合によって角度を調整するもの（特許文献１）は、一方向角度調整であった。また連結片と支持片により角度を調節したもの（特許文献２）が提案されている。次に連結片と、支持片により角度を調節するもの（特許文献３）の提案もある。更に垂直軸周りで相互回動し、屈折角度を調節できるようにした接続部（特許文献４）の提案もある。   Conventionally, the one that adjusts the angle by fitting the adjustment ring (Patent Document 1) is one-way angle adjustment. Further, there has been proposed a device in which the angle is adjusted by a connecting piece and a supporting piece (Patent Document 2). Next, there is also a proposal (Patent Document 3) in which the angle is adjusted by a connecting piece and a supporting piece. Furthermore, there is also a proposal of a connecting portion (Patent Document 4) that can rotate around the vertical axis and adjust the refraction angle.

前記のように、公知技術は何れも一方向屈曲調整であって、水平方向と、垂直方向を同一箇所で簡単に、かつ同時に調節できるようにした発明考案の提案が少ない。   As described above, all of the known techniques are unidirectional bending adjustments, and there are few proposals of the invention that can easily and simultaneously adjust the horizontal direction and the vertical direction at the same place.

然し乍ら水平、垂直の両方向に調整できた方がよいことは当然であり、前記問題点の更なる改善を要請されていた。   However, it is a matter of course that it is better to be able to adjust both the horizontal and vertical directions, and further improvement of the above problems has been demanded.

然るにこの発明は、角度及び位置の調整が容易な継手を用いることにより、同一場所において、お互いのセンター芯もぶれないで水平方向の角度と、垂直方向の角度を同時に調節することに成功し、前記従来の問題点を解決したのである。   However, the present invention succeeded in adjusting the horizontal angle and the vertical angle at the same place by using a joint whose angle and position can be easily adjusted without causing the center cores of each other to be shaken. The conventional problems have been solved.

Circular holes 13, 13, 13 of connecting pipes 10, 10, 10 are respectively fitted to the left and right of the outer wall portion of the hollow sphere 9, and arc-shaped partition plates 12, 13, 13 are respectively inserted into the circular holes 13, 13, 13. 12 and 12 are provided (FIG. 26 ). The partition plates 12, 12, 12 are provided with grooves 15, 15, 15 through which one end portions of the mounting rods 14, 14, 14 are inserted in diameter with respect to the circular holes 13, 13, 13. 12 and 12 are rough surfaces (opposite side surfaces of the circular holes), and are in frictional contact with the seat plates 16, 16, and 16 fitted to the mounting rods 14, 14, and 14.

前記取付杆１４、１４、１４の他端部には、リング部１４ａ、１４ａ、１４ａを設けて、前記中空球体９の中央部で上下に重ねる。前記中空球体９には、上部から、固定ボルト１７が挿通され、該固定ボルト１７の下端部は前記ブラケット６の上端部６ｂ上の円板５８に固定したナット１８に螺合させてあり、前記固定ボルト１７のコーン部１７ａを、前記リング部１４ａ内へ挿入させると、コーン部１７ａの外壁によって、夫々のリング部１４ａを矢示１９、１９の方向（図２５、内向）へ引張るので、取付杆１４、１４、１４も同方向へ引張られ、取付杆１４、１４、１４のナット２０、２０、２０を介して接続管１０、１０、１０を夫々中心部へ引込み、中空球体９と、接続管１０、１０、１０との自在継手を完結固定する。前記固定ボルト１７はナット１８に螺合して安定保持されている。 Ring portions 14 a, 14 a, 14 a are provided at the other end portions of the mounting rods 14, 14, 14, and are stacked vertically at the central portion of the hollow sphere 9. A fixing bolt 17 is inserted into the hollow sphere 9 from above, and a lower end portion of the fixing bolt 17 is screwed to a nut 18 fixed to a disk 58 on the upper end portion 6b of the bracket 6. When the cone portion 17a of the fixing bolt 17 is inserted into the ring portion 14a, the outer wall of the cone portion 17a pulls each ring portion 14a in the direction of arrows 19 and 19 (FIG. 25 , inward). The rods 14, 14, and 14 are also pulled in the same direction, and the connecting pipes 10, 10, and 10 are pulled into the center through the nuts 20, 20, and 20 of the mounting rods 14, 14, and 14, respectively. The universal joint with the pipes 10, 10, 10 is completely fixed. The fixing bolt 17 is screwed into a nut 18 and is stably held.

これにより中空球体９と、接続管１０、１０、１０よりなる自在継手１００は、ブラケット６上へ固定される。図中２７、２７は手摺りである（図２４）。 Thereby, the universal joint 100 including the hollow sphere 9 and the connecting pipes 10, 10, 10 is fixed onto the bracket 6. In the figure, 27 and 27 are handrails (FIG. 24 ).

前記において、キャップ６７を外し、固定ボルト１７を弛めると、コーン部１７ａの上昇により取付杆１４、１４、１４のリング部１４ａ、１４ａ、１４ａが弛むので、接続管１０、１０、１０は図２４（ａ）のように矢示２５、２６の方向へ自由に移動することができる。また上下部の中空球体９ａ、９ｂも図２４（ｂ）中矢示２３、２４の方向へ自由に回動する。従って、接続管１０、１０、１０は水平方向（中空球体９の回動）及び垂直方向（接続管１０の上下斜方向の移動）へ移動できるので、立体的又は全方位に自由移動（自在継手）調節をすることができる。 In the above, the uncapped 67, when loosened fixing bolt 17, the ring portion 14a of mounting rod 14, 14, 14 by increasing the cone portion 17a, 14a, since 14a slackens, the connection pipe 10, 10, 10 Figure 24 It can move freely in the direction of arrows 25 and 26 as shown in (a). The upper and lower portions of the hollow spheres 9a, 9b also free to rotate in the direction shown in FIG. 24 (b) Nakaya shows 23,24. Accordingly, since the connecting pipes 10, 10, and 10 can move in the horizontal direction (rotation of the hollow sphere 9) and the vertical direction (movement of the connecting pipe 10 in the up and down oblique direction), they can freely move in three dimensions or in all directions (universal joints). ) Can be adjusted.

前記のように、固定ボルト１７を弛めることにより、接続管１０の角度を自在に微調節することができるので、現場における調整が簡単容易、かつ確実になる効果がある。   As described above, by loosening the fixing bolt 17, the angle of the connecting pipe 10 can be freely finely adjusted. Therefore, there is an effect that the adjustment at the site is easy, easy and reliable.

前記実施例においては、取付杆１４を三本用いるので、リング部の重なりが高くなる。そこで上下中空球体９ａ、９ｂの当接部間へリング８５を介装して、段差を解消し併せて、接続管１０、１０、１０を夫々立体的に円滑に回動させる為である。またリング部１４ａは扁平にして全体の重なりを薄くしてある。   In the said Example, since the three attachment rods 14 are used, the overlap of a ring part becomes high. Therefore, the ring 85 is interposed between the contact portions of the upper and lower hollow spheres 9a and 9b to eliminate the step and to smoothly rotate the connecting pipes 10, 10, and 10 in three dimensions. The ring portion 14a is flattened to reduce the overall overlap.

この発明の他の実施例を図２７〜３１について説明する。この実施例は、実施例７における一つの接続管１０に代えて、案内板８６の柱８６ａを嵌挿する筒体８７を固定するブラケット８８の取付板８８ａを、取付杆１４のリング部１４ａで挟着固定したものに相当する。従って接続管１０、１０、取付杆１４、１４、固定ボルト１７、コーン部１７ａ、ブラケット６などの構造は総て同一に付、同一部分は同一符号をつけ、その説明を省略した。   Another embodiment of the present invention will be described with reference to FIGS. In this embodiment, instead of the single connecting pipe 10 in the seventh embodiment, the mounting plate 88a of the bracket 88 for fixing the cylindrical body 87 into which the column 86a of the guide plate 86 is inserted is replaced by the ring portion 14a of the mounting rod 14. Corresponds to pinched and fixed. Accordingly, the structures of the connecting pipes 10 and 10, the mounting rods 14 and 14, the fixing bolt 17, the cone portion 17a, the bracket 6 and the like are all the same, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

前記のように、接続管１０、１０については総て実施例１におけるとおりであって、同一部分には同一符号を付した。従って同一部分の構成作用効果は総て同一に付、その説明を省略した。   As described above, the connecting pipes 10 and 10 are all the same as in the first embodiment, and the same portions are denoted by the same reference numerals. Therefore, the same configuration and effect of the same portion are all the same, and the description thereof is omitted.

前記実施例において、ブラケット８８の取付板８８ａを、取付杆１４、１４のリング１４ａ、１４ａの間に挟着し、固定ボルト１７を螺入（ナットへ締め付ける）すれば、前記取付杆１４、１４の固定に伴って、取付板８８ａも固定される。そこでブラケット８８が固定されるので、ブラケット８８の固定片８８ｂへ、筒体８７をボルト８９で固定する。そこで展示すべき案内板８６の柱を、前記筒体８７に挿入すれば、案内板８６を安定保持することができる。   In the above embodiment, when the mounting plate 88a of the bracket 88 is sandwiched between the rings 14a and 14a of the mounting rods 14 and 14, and the fixing bolt 17 is screwed (tightened to the nut), the mounting rods 14 and 14 are mounted. With the fixing of the mounting plate 88a, the mounting plate 88a is also fixed. Therefore, since the bracket 88 is fixed, the cylinder 87 is fixed to the fixing piece 88b of the bracket 88 with the bolt 89. Therefore, if the column of the guide plate 86 to be displayed is inserted into the cylindrical body 87, the guide plate 86 can be stably held.

次に図３０、３１は、前記案内板（その他広告等）に代えてデリネーター９０を取り付ける場合の一例を示すものである。前記デリネーター９０は視線誘導標で、いわゆる「道路交通安全用品」であって、その様式に関係なく、同一技術により、この発明の自在継手部へ取り付けることができる。前記デリネーター９０は、取付板９０ａと、支持部９０ｂと、表示部９０ｃとを一体に形成したものであるが、前記各部を別製して然る後連結することを妨げない。 Next, FIGS. 30 and 31 show an example in which a delineator 90 is attached instead of the guide plate (other advertisements, etc.). The delineator 90 is a line-of-sight guide mark, which is a so-called “road traffic safety article”, and can be attached to the universal joint portion of the present invention by the same technique regardless of its style. The delineator 90 is formed by integrally forming the mounting plate 90a, the support part 90b, and the display part 90c, but does not prevent the parts from being manufactured separately and then connected.

この発明の他の実施例を図３２、３３、３４に基づいて説明する。この実施例は、接続管１０を４個取り付けたもので、その他は実施例１と同一である。従って各部の構成中、接続管１０が４個あること、これに伴って取付杆１４のリング部１４ａの重なりが大きくなるので、上下中空球体９ａ、９ｂの間にリング８５、８５ａを介装して安定を図った。またリング部１４ａは、ほぼ２分の１の厚さとして、全体の重なりを可及的に薄く収めた。この点は重なりが４本分であっても、リング８５、８５ａの厚さによって調節することができると共に、各接続管１０、１０、１０、１０を夫々立体的に摺動させることができるようにしてある。またリング８５、８５ａの切目に取付杆が嵌るようにしてある。 Another embodiment of the present invention will be described with reference to FIGS. In this embodiment, four connecting pipes 10 are attached, and the others are the same as in the first embodiment. Accordingly, in the configuration of each part, since there are four connecting pipes 10 and the overlap of the ring part 14a of the mounting rod 14 increases accordingly, the rings 85 and 85a are interposed between the upper and lower hollow spheres 9a and 9b. And aimed for stability. Further, the ring portion 14a has a thickness of almost one half, and the entire overlap is made as thin as possible. This point can be adjusted by the thickness of the rings 85 and 85a even when there are four overlaps, and each connecting pipe 10, 10, 10, 10 can be slid three-dimensionally. It is. Further it is as attaching lever fits into the cut-th ring 85, 85a.

前記のように基本的構造は実施例１と同一であるから、同一部分については同一符号を付し、その構成、作用、効果の説明を省略した。但し４本の笠木などを接続できる。   Since the basic structure is the same as that of the first embodiment as described above, the same portions are denoted by the same reference numerals, and the description of the configuration, operation, and effect is omitted. However, 4 caps can be connected.

この発明の他の実施例を図３５〜３８について説明すると、笠木３０、３０の下面に蝶板３１の一側蝶板片３１ａを夫々固定し、蝶板３１の他側蝶板片３１ｂの長孔３１ｃと、回転接続枠３２、３３の垂直枠３２ａ、３３ａの縦溝３２ｂ、３３ｂをボルト３４、３４で固定する。前記回転接続枠３２の水平片３２ｃ、円形案内部３２ｄに、回転接続枠３３の水平片３３ｃの弧状部３３ｄを回動自在に嵌装し、その上部を案内筒３５の下面で押え、前記案内筒３５をベース３６の縦軸３７へ回転自在に嵌装し、ビス３８を前記縦軸３７の上端へ螺合し固定して、この発明の継手４６ができる。前記ベース３６は、支柱３９上へ固定されている。図中４７は格子、４８は下部横桟である。   Another embodiment of the present invention will be described with reference to FIGS. 35 to 38. One side butterfly plate 31a of the butterfly plate 31 is fixed to the lower surfaces of the caps 30 and 30, respectively, and the length of the other side butterfly plate 31b of the butterfly plate 31 is fixed. The holes 31 c and the vertical grooves 32 b and 33 b of the vertical frames 32 a and 33 a of the rotary connection frames 32 and 33 are fixed by bolts 34 and 34. An arcuate portion 33d of the horizontal piece 33c of the rotary connection frame 33 is rotatably fitted to the horizontal piece 32c and the circular guide portion 32d of the rotary connection frame 32, and the upper part thereof is pressed by the lower surface of the guide tube 35, and the guide The cylinder 35 is rotatably fitted to the longitudinal axis 37 of the base 36, and the screw 38 is screwed to and fixed to the upper end of the longitudinal axis 37, whereby the joint 46 of the present invention can be made. The base 36 is fixed onto a column 39. In the figure, 47 is a lattice, and 48 is a lower horizontal rail.

前記において、笠木３０の傾斜角度は矢示４０又は４１の方向へ上下することにより（図３５）、蝶板３１ａが回動して支持設定する。また各笠木３０の高さは、蝶板３１ｂを矢示４２又は４３の方向へ昇降することによって所定の高さに設定できる。 In the above, the inclination angle of the headboard 30 is raised and lowered in the direction of the arrow 40 or 41 (FIG. 35 ), so that the butterfly plate 31a is rotated and supported. The height of each headboard 30 can be set to a predetermined height by raising and lowering the butterfly plate 31b in the direction of the arrow 42 or 43.

次に笠木３０の水平方向の角度は、前記回転接続枠３２、３３を矢示４４又は４５の方向へ回転させることにより、自由に設定することができる（図３５（ｂ））。 Next, the horizontal angle of the headboard 30 can be freely set by rotating the rotary connection frames 32 and 33 in the direction of the arrow 44 or 45 (FIG. 35B ).

前記における回転は、回転接続枠３２の円形案内部３２ｄと、回転接続枠３３の弧状部３３ｄとの嵌合により案内されるので、総て縦軸３７を中心にして行われる。従って、回転の中心は常時正確に保持されており、回転角によって回転の中心がぶれるおそれはない。   Since the rotation is guided by the fitting of the circular guide portion 32d of the rotary connection frame 32 and the arc-shaped portion 33d of the rotary connection frame 33, the rotation is performed around the vertical axis 37. Therefore, the center of rotation is always maintained accurately, and there is no possibility that the center of rotation will fluctuate depending on the rotation angle.

前記のように、笠木３０は、その接続部において、垂直方向、水平方向及び接続高さを自由に調整できるので、現場の形状に応じ、正確に対応して施工することができる。   As described above, since the headboard 30 can freely adjust the vertical direction, the horizontal direction, and the connection height at the connection portion, it can be constructed in accordance with the shape of the site.

この発明の他の実施例を図３９、４０に基づいて説明すると、笠木３０、３０の端部内側へ同形の角切りスリーブ５０、５０を夫々内装し、前記角切りスリーブ５０、５０の両側長手方向へ設けた円形筒５１、５１内へ、一端鍔付のフレキシブルパイプ５２、５２を夫々挿通し、前記フレキシブルパイプ５２、５２の他端部５２ａ、５２ａを屈折し、前記角切りスリーブ５０、５０と、フレキシブルパイプ５２、５２とを長手方向について固着する。   Another embodiment of the present invention will be described with reference to FIGS. 39 and 40. Square cut sleeves 50 and 50 having the same shape are provided inside the ends of the caps 30 and 30, respectively. The flexible pipes 52 and 52 with one end ribs are respectively inserted into the circular cylinders 51 and 51 provided in the direction, the other end portions 52a and 52a of the flexible pipes 52 and 52 are refracted, and the square-cut sleeves 50 and 50 are bent. Then, the flexible pipes 52 and 52 are fixed in the longitudinal direction.

前記において図３９（ｂ）中矢示５４又は５５のように外力を加えると、前記フレキシブルパイプ５２が自由に屈曲するので、所定の位置で前記角切りスリーブ５０を固定すれば、笠木３０を所定の角度で安定保持することができる。 In FIG. 39 (b), when an external force is applied as shown by the arrow 54 or 55 in FIG. 39 (b), the flexible pipe 52 freely bends. Therefore, if the square sleeve 50 is fixed at a predetermined position, the head 30 is It can be held stably at an angle.

前記図３９（ｂ）は水平方向の角度調整であるが、図３９（ｃ）のように矢示５６又は５７の方向へ外力を加えれば、垂直方向の角度調整をすることもできる。 FIG. 39 (b) shows the horizontal angle adjustment, but if an external force is applied in the direction of the arrow 56 or 57 as shown in FIG. 39 (c), the vertical angle adjustment can also be performed.

図中５９、５９は目地コーキング受板で、笠木ジョイント目地にコーキング充填の必要な場合に取り付ける。   In the figure, reference numerals 59 and 59 denote joint caulking receiving plates, which are attached when caulking filling is required on the coping joint.

次にスリーブ５０の取付状態を図４０に基づいて説明すると、スリーブ５０を笠木３０内へ挿入し、笠木３０の角度を決定したならば、ボルト４９により笠木３０の取付けブラケット２９と、スリーブ５０をボルト４９で固定することにより、スリーブ５０の位置が決まり、笠木３０の角度も確定される。前記取付けブラケット２９の他端は支柱６０へボルト６１で固定されている。 Turning now describes the group Dzu the mounting state of the sleeve 50 in FIG. 40, by inserting the sleeve 50 into the coping 30, if determined the angle of coping 30, the mounting bracket 29 of the coping 30 by a bolt 49, the sleeve 50 Is fixed with a bolt 49, the position of the sleeve 50 is determined, and the angle of the headboard 30 is also determined. The other end of the mounting bracket 29 is fixed to the column 60 with a bolt 61.

また笠木３０の継目へコーキングする場合には、継目３０ａの内側をコーキング受板５９で塞ぎ（図３９（ｂ））、ついでコーキング材２８を充填する。この場合に、コーキング受板５９があるので、対向する笠木３０、３０の隙間へ確実にコーキングすることができる。
