Description

本発明は、住宅や公共建築等の建物に取付ける手すりに関するものである。 The present invention relates to a handrail attached to a building such as a house or a public building.

住宅や公共建築等の建物に取付ける手すりにおいては、壁面等の取付対象物に固定される取付ブラケットによって笠木を支承させる構造となっている。笠木は、筒状の芯材を被覆材で被覆したものが多く用いられるが、芯材を鉄系金属材で形成し、被覆材を合成樹脂で形成したものが一般的となっている。 BACKGROUND ART A handrail attached to a building such as a house or a public building has a structure in which a cap is supported by a mounting bracket fixed to a mounting object such as a wall surface. As the cap, a material obtained by covering a cylindrical core material with a coating material is often used, and a material in which the core material is formed of an iron-based metal material and the coating material is formed of a synthetic resin is generally used.

特許文献１には、取付ブラケットに、外筒部と外筒部の径方向内方側において内筒部とを形成して、中空状の笠木の端部を、外筒部内に嵌合させると共に、笠木の中空孔内に内筒部を嵌合させるものが開示されている。そして、特許文献１のものでは、笠木の端部の外周面を皮むき加工（段状に縮径する加工）を行ったのち、外筒部に嵌合させるようにしてある。特に、被覆材の外周面に滑り止めの凹凸加工が施されている場合に、この笠木の外周面と外筒部の内周面との間の隙間から水が取付ブラケット内に侵入し易く、腐食やカビの原因となることから、この凹凸部分を除去するように上記皮むき加工を行ない、笠木の端部の段状部位を外筒部の先端開口縁に密着させている。 Patent Literature 1 discloses that an outer cylinder portion and an inner cylinder portion are formed on a mounting bracket on a radially inner side of the outer cylinder portion, and an end of a hollow cap is fitted into the outer cylinder portion. A fitting in which an inner cylindrical portion is fitted into a hollow hole of a skirting is disclosed. And in the thing of patent document 1, after peeling the outer peripheral surface of the edge part of a sash (the process of reducing a diameter in steps), it fits in an outer cylinder part. In particular, when the outer peripheral surface of the coating material is subjected to anti-slip irregularity processing, water easily enters the mounting bracket from the gap between the outer peripheral surface of the coping and the inner peripheral surface of the outer cylindrical portion, Since it causes corrosion and mold, the above-mentioned peeling process is performed so as to remove the uneven portion, and the stepped portion at the end of the casket is brought into close contact with the opening edge of the distal end of the outer cylinder portion.

ところで、最近では、手すりの取付現場において笠木を所望長さに切断して、取付ブラケットに取付ける、という要請が強くなっている。しかしながら、芯材を鉄系金属材で形成した従来の笠木では、高速切断機や電動のこぎりにより切断する際に火花が激しく生じて、合成樹脂製の被覆材や取付現場の壁面・床面などを焼損させ、さらには火災を引起こすおそれもあった。また、芯材を鉄系金属材で形成した従来の笠木では、金鋸等の手工具で切断するのに多大の時間と労力を要して、事実上採用しがたいものであった。 By the way, recently, there has been a strong demand that a cap is cut to a desired length and attached to a mounting bracket at a handrail mounting site. However, in the conventional Kasagi made of iron-based metal as the core material, sparks are violently generated when cutting with a high-speed cutting machine or an electric saw, and the synthetic resin coating material and the wall and floor of the installation site are damaged. There was a risk of burning and even a fire. Further, in the conventional Kasagi having a core material formed of an iron-based metal material, cutting with a hand tool such as a gold saw requires a great deal of time and labor, and is practically difficult to employ.

また、上述の笠木の皮むき加工は、工場の工作機械によって行われている。そのため、取付現場において笠木を所望の長さに切断しても、その取付現場で皮むき加工を行うことができなかった。 In addition, the above-mentioned peeling of the casket is performed by a machine tool in a factory. For this reason, even if the cap is cut to a desired length at the installation site, the peeling cannot be performed at the installation site.

また、特許文献２に開示されるように、外筒部の先端開口縁と笠木の端部の段状部位との間に目地パッキンを介在させることも可能だが（図３の符合１１参照）、目地パッキンが外部に露出して見栄えが悪く、さらに使用により目地パッキンにカビが発生して見栄えが悪化するという問題もある。 Further, as disclosed in Patent Literature 2, it is also possible to interpose joint packing between the opening edge of the outer cylindrical portion and the stepped portion of the end of the coping (see reference numeral 11 in FIG. 3). There is also a problem that the joint packing is exposed to the outside and the appearance is poor, and furthermore, the use of the joint packing causes mold to deteriorate the appearance.

本発明は以上のような事情を勘案してなされたもので、その目的は、手すりの取付現場において笠木を所望長さに切断して、シール性を確保しつつ取付ブラケットに笠木を容易に取付けることができ、さらには見栄えを損なわないようにした手すりを提供することにある。 The present invention has been made in view of the above circumstances, and an object of the present invention is to cut a shed to a desired length at a handrail installation site, and easily attach the shed to a mounting bracket while ensuring sealing performance. And to provide a handrail that does not impair the appearance.

According to the fourth aspect of the invention, in addition to the functions and effects of the above-described basic solution, the following unique functions and effects are further exhibited. That is, even if burrs of the core material are generated at the end of the cap tree cut at the installation site, when the seal member is pressed against the inner bottom by the end face of the cap, the seal member pressed by the burrs of the core material is in the escape groove. Therefore, it is possible to absorb variations due to burrs of the core material.

本件第１発明〜本件第４発明の好ましい態様は次のとおりである。
前記芯材がアルミニウム系金属または硬質合成樹脂によって形成され、
前記被覆材が合成樹脂により形成されている、
ようにすることができる。この場合、高速切断機や電動のこぎり等の電動工具や金鋸等の手工具によって笠木を極めて簡単かつ短時間で切断することができる。また、被覆材によって、芯材の保護と好ましい手触り感を確保することができる。また、電動工具で笠木を切断する際に火花が飛び散らないため、笠木の被覆材や取付現場の壁面・床面などが焼損することを防止できる。 Also, by reducing the contact area of the inner cylinder portion with the core material, the guide rib is relatively easily elastically deformed when the core material is to be fitted obliquely with the core material slightly shifted from the inner cylinder portion. Thus, the core material is guided so as to be smoothly fitted to the inner cylindrical portion.
Preferred aspects of the first to fourth inventions are as follows.
The core material is formed of an aluminum-based metal or a hard synthetic resin,
The coating material is formed of a synthetic resin,
You can do so. In this case, it is possible to cut the coping very easily and in a short time with a high-speed cutting machine, an electric tool such as an electric saw, or a hand tool such as a metal saw. In addition, the covering material can protect the core material and secure a favorable touch feeling. In addition, since sparks are not scattered when cutting the cover with the electric tool, it is possible to prevent the covering material of the cover and the wall and floor at the installation site from burning.

本発明によれば、手すりの取付現場において笠木を所望長さに切断して、シール性を自動的に確保しつつ取付ブラケットに対して笠木を容易に取付けることができる。また、本発明によれば、シール部材が外部に露出しないので、手すりの見栄えを損なうこともない。 ADVANTAGE OF THE INVENTION According to this invention, a cap can be cut | disconnected to a desired length at the mounting site of a handrail, and a cap can be easily attached to a mounting bracket, automatically ensuring sealing performance. Further, according to the present invention, since the seal member is not exposed to the outside, the appearance of the handrail is not impaired.

図１において、手すりＴは、左右一対の取付ブラケット１０と、左右一対の取付ブラケット１０に支承された笠木２０とを有する。笠木２０は、図１、図４、図５に示すように、筒状（実施形態では円筒状）の芯材２１と、芯材２１の外表面を被覆する被覆材２２と、を有する。笠木２０は、手すりの取付現場において高速切断機や電動のこぎり等の電動工具や金鋸等の手工具によって容易に切断できるように、その芯材２１が、アルミニウム系金属によって形成されている。また、被覆材２２は、従来同様に合成樹脂により略円筒状に成形されている。そして、被覆材２２の周方向一部には、滑り止めとして、笠木２０の長手方向に小間隔をあけて多数の凹部（あるいは凸部）２２ａが形成されている（実施形態では、笠木２０の周方向に伸びる楕円形とされている）。なお、芯材２１は、硬質合成樹脂によって形成されてもよい。 In FIG. 1, the handrail T has a pair of left and right mounting brackets 10 and a cap 20 supported by the pair of left and right mounting brackets 10. As shown in FIGS. 1, 4, and 5, the cap 20 has a cylindrical (cylindrical in the embodiment) core material 21 and a coating material 22 that covers the outer surface of the core material 21. The core material 21 is formed of an aluminum-based metal so that the cap 20 can be easily cut by a power tool such as a high-speed cutting machine or an electric saw or a hand tool such as a gold saw at a handrail mounting site. The covering member 22 is formed in a substantially cylindrical shape using a synthetic resin as in the conventional case. A large number of concave portions (or convex portions) 22a are formed in a part of the covering material 22 in the circumferential direction at small intervals in the longitudinal direction of the cover 20 as slip stoppers (in the embodiment, the cover 20 has It is an oval extending in the circumferential direction). The core 21 may be formed of a hard synthetic resin.

実施形態では、芯材２１内に筒状の補強パイプ２３が挿入されて、笠木２０の曲げ剛性（強度）が向上された構造となっている。補強パイプ２３は、芯材２１と同様にアルミニウム系金属により形成してある。補強パイプ２３は、芯材２１よりも短くされて、取付ブラケット１０に対する取付けとは無関係とされている。このような補強パイプ２３は、笠木２０が所定長さ（例えば８０ｃｍ）以上の場合にのみ用いるようになっており、このため、芯材２１内にスムーズに挿入できるように芯材２１の内径よりも若干小さい外径に設定されている。 In the embodiment, a tubular reinforcing pipe 23 is inserted into the core 21 so that the bending rigidity (strength) of the cap 20 is improved. The reinforcing pipe 23 is formed of an aluminum-based metal similarly to the core material 21. The reinforcing pipe 23 is shorter than the core member 21 and is not related to attachment to the attachment bracket 10. Such a reinforcing pipe 23 is used only when the coping 20 has a predetermined length (for example, 80 cm) or more. For this reason, the inner diameter of the core 21 is set so that it can be smoothly inserted into the core 21. Is also set to a slightly smaller outer diameter.

取付ブラケット１０は、大別して、ベース部１０Ａと、笠木取付部１０Ｂと、ベース部１０Ａと笠木取付部１０Ｂとを連結する連結部１０Ｃと、を有する。連結部１０Ｃは、エルボ状に湾曲されている。そして、取付ブラケット１０は、全体的に合成樹脂によって型成形（例えば射出成形）されている。 The mounting bracket 10 roughly includes a base part 10A, a hessian mounting part 10B, and a connecting part 10C for connecting the base part 10A and the hessian mounting part 10B. The connecting portion 10C is curved in an elbow shape. The mounting bracket 10 is entirely molded (for example, injection molded) of a synthetic resin.

上記ベース部１０Ａは、図示を略す取付ネジによって、建物の壁面等の取付面１に対して固定される。この固定のために、図２に示すように、ベース部１０Ａには、複数の取付孔１１が形成されている。複数の取付孔１１は、円形状のものと、長円形状のものとが混在されたものとされている。長円形状の取付孔１１を利用した取付けは、上記取付ねじとベース部１０Ａとの位置関係を大きく調整して取付ける際に用いて好適である。また、取付ブラケット１０のベース部１Ａは、合成樹脂製のカバー部材１２でもって被覆される。 The base portion 10A is fixed to a mounting surface 1 such as a wall surface of a building by mounting screws (not shown). For this fixation, a plurality of mounting holes 11 are formed in the base portion 10A as shown in FIG. The plurality of mounting holes 11 are a mixture of a circular hole and an elliptical hole. The attachment using the elliptical attachment hole 11 is suitable for use when the positional relationship between the attachment screw and the base portion 10A is largely adjusted and attached. The base portion 1A of the mounting bracket 10 is covered with a cover member 12 made of synthetic resin.

取付ブラケット１０における笠木取付部１０Ｂは、次のような構造となっている。笠木取付部１０Ｂは、先端開口部３８を有する外筒部３１と、外筒部３１の径方向内方側に位置する内筒部３２とを有する。外筒部３１と内筒部３２とは、開口断面形状がそれぞれ円形とされて、互いに同心状となるように形成されている。そして、内筒部３２は、外筒部３１の先端開口部３８からさらに長く伸びて、内筒部３２の先端部が外筒部３１の外部に突出するようにされている。 The sash mounting portion 10B of the mounting bracket 10 has the following structure. The cap mounting portion 10B includes an outer cylindrical portion 31 having a distal end opening 38, and an inner cylindrical portion 32 located radially inward of the outer cylindrical portion 31. The outer cylinder part 31 and the inner cylinder part 32 are formed so that the opening cross-sections are respectively circular and concentric with each other. The inner cylinder 32 extends further from the distal end opening 38 of the outer cylinder 31 so that the distal end of the inner cylinder 32 projects outside the outer cylinder 31.

上記外筒部３１の内周面と内筒部３２の外周面との間には、環状の嵌合凹部３３が形成される。また、嵌合凹部３３の奥側には、外筒部３１の内周面と内筒部の外周面３２とを連結する内底部３９が形成される。この嵌合凹部３３の幅、換言すると、外筒部３１の内周面と内筒部３２の外周面との間の径方向距離は、笠木２０の厚さ（つまり芯材２１と被覆材２２との合計厚さ）よりも大きく設定されている。 An annular fitting recess 33 is formed between the inner peripheral surface of the outer cylindrical portion 31 and the outer peripheral surface of the inner cylindrical portion 32. Further, an inner bottom portion 39 that connects the inner peripheral surface of the outer cylindrical portion 31 and the outer peripheral surface 32 of the inner cylindrical portion is formed on the inner side of the fitting concave portion 33. The width of the fitting concave portion 33, in other words, the radial distance between the inner peripheral surface of the outer cylindrical portion 31 and the outer peripheral surface of the inner cylindrical portion 32 is determined by the thickness of the coping 20 (that is, the core material 21 and the coating material 22). Is set to be larger than the total thickness.

内筒部３２の外径は、芯材２１の内径よりも若干小さく設定されて、内筒部３２の外周に芯材２１が嵌合できるようにされている。また、笠木２０の外径は、外筒部３１の内径と同一又は僅かに小さく設定されて、笠木２０端部の被覆材２２を皮むき加工する等のことなく、外筒部３１内に笠木２０の端部を嵌合できるようにされている。 The outer diameter of the inner cylinder 32 is set slightly smaller than the inner diameter of the core 21 so that the core 21 can be fitted to the outer periphery of the inner cylinder 32. Further, the outer diameter of the cap 20 is set to be the same as or slightly smaller than the inner diameter of the outer tube 31, so that the covering material 22 at the end of the cap 20 is not peeled off, and the cap is placed inside the outer tube 31. 20 can be fitted.

ここで、笠木２０の端部を笠木取付部１０Ｂに容易に挿入、嵌合できるように、次のような寸法設定にするのが好ましい。まず、前述したように、基本的に、芯材２１の内径ａが内筒部３２の外径ｂよりも大きくされる。また、被覆材２２を含む笠木２０の外径ｃが、外筒部３１の内径ｄ以下とされる。 Here, it is preferable to set the following dimensions so that the end of the cap 20 can be easily inserted and fitted into the cap mounting portion 10B. First, as described above, basically, the inner diameter a of the core member 21 is made larger than the outer diameter b of the inner cylindrical portion 32. Further, the outer diameter c of the cap 20 including the covering material 22 is set to be equal to or less than the inner diameter d of the outer cylindrical portion 31.

そして、上記各寸法ａ〜ｄが、（ａ−ｂ）＞（ｄ−ｃ）の関係を満足する設定とするのが好ましい。これにより、内筒部３２が外筒部３１の先端開口部３８よりも外方に伸びていることと合わせて、笠木２０の芯材２１の端部を笠木取付部１０Ｂの内筒部３２に挿入、嵌合させる取付作業が容易となり、さらに笠木２０の被覆材２２と外筒部３１の内周面との隙間を小さくすることができる。すなわち、先ず芯材２１の先端開口に内筒部３２を挿入させていき、この内筒部３２をガイドとしつつ笠木２０を外筒部３１内に挿入させることができ、この場合、嵌合凹部３３に笠木２０の端部が挿入、嵌合されることになる。 It is preferable that the dimensions a to d satisfy the relationship of (ab)> (dc). Accordingly, the end of the core 21 of the coping 20 is attached to the inner cylinder 32 of the coping attachment 10B, in addition to the fact that the inner cylinder 32 extends outward beyond the distal end opening 38 of the outer cylinder 31. Insertion and fitting work becomes easy, and the gap between the covering material 22 of the cap 20 and the inner peripheral surface of the outer cylindrical portion 31 can be reduced. That is, first, the inner tubular portion 32 is inserted into the distal end opening of the core member 21, and the cap 20 can be inserted into the outer tubular portion 31 while using the inner tubular portion 32 as a guide. The end of the coping 20 is inserted into and fitted to 33.

取付ブラケット１０に対して笠木２０を固定するため、笠木２０の端部には、取付孔２４が形成されている（図４参照）。また、取付ブラケット１０には、外筒部３１の位置において、挿入孔４２が形成されており、内筒部３２における挿入孔４２に対応する位置に、ねじ孔４１が形成されている。挿入孔４２の直径は、固定ねじ４３のねじ頭よりも大きくされている。笠木２０の端部を笠木取付部１０Ｂに取付けた（嵌合させた）状態で、図４に示すように、取付孔２４から挿入される固定ねじ４３を、取付孔２４及びねじ孔４１にねじ込むことによって、取付ブラケット１０と笠木２０とが固定されて、笠木２０の抜け止め及び回り止めが行われる。 In order to fix the cap 20 to the mounting bracket 10, a mounting hole 24 is formed at an end of the cap 20 (see FIG. 4). An insertion hole 42 is formed in the mounting bracket 10 at the position of the outer cylinder portion 31, and a screw hole 41 is formed at a position corresponding to the insertion hole 42 in the inner cylinder portion 32. The diameter of the insertion hole 42 is larger than the screw head of the fixing screw 43. In a state where the end portion of the cap 20 is attached (fitted) to the cap attachment portion 10B, a fixing screw 43 inserted from the attachment hole 24 is screwed into the attachment hole 24 and the screw hole 41 as shown in FIG. As a result, the mounting bracket 10 and the coping 20 are fixed, so that the coping 20 is prevented from coming off and from rotating.

ここで、図３、図４に示すように、笠木取付部１０Ｂの内底部３９は、外筒部３１の内周面より段状に縮径された着座面３５を有している。また、笠木取付部１０Ｂの内底部３９には、嵌合凹部３３に連なるように奥方向に窪んだ逃げ溝３４が形成されている。この逃げ溝３４は、外筒部３１や内筒部３２と同心の円環状に、内筒部の外周を取り巻くように形成されている。逃げ溝３４の最大径は、外筒部３１の内径よりも小さく設定されている。 Here, as shown in FIG. 3 and FIG. 4, the inner bottom portion 39 of the coping attachment portion 10 </ b> B has a seating surface 35 whose diameter is reduced stepwise from the inner peripheral surface of the outer cylindrical portion 31. In addition, a relief groove 34 that is recessed in the depth direction so as to be continuous with the fitting recess 33 is formed in the inner bottom portion 39 of the cap mounting portion 10B. The clearance groove 34 is formed in an annular shape concentric with the outer cylindrical portion 31 and the inner cylindrical portion 32 so as to surround the outer periphery of the inner cylindrical portion. The maximum diameter of the relief groove 34 is set smaller than the inner diameter of the outer cylindrical portion 31.

逃げ溝３４を横断する複数の連結リブ３６が、内筒部３２の周方向等間隔に複数（実施形態では図３に示すように８個）形成されている。連結リブ３６は着座面３５とほぼ面一に形成されている。図５では、連結リブ３６がハッチング部分（中実構造）でもって示されており、図５中一点鎖線でもって逃げ溝３４を示してある。 A plurality (eight in the embodiment, as shown in FIG. 3) of a plurality of connecting ribs 36 traversing the clearance groove 34 are formed at equal intervals in a circumferential direction of the inner cylindrical portion 32. The connecting rib 36 is formed substantially flush with the seating surface 35. In FIG. 5, the connecting rib 36 is indicated by a hatched portion (solid structure), and the escape groove 34 is indicated by an alternate long and short dash line in FIG.

図４、図５に示すように、円環状の弾性体からなるシール部材５０が、内筒部３２を挿通されて内底部３９に当接するように嵌合凹部３３内に配置されている。シール部材５０は、弾性を有する合成樹脂やエラストマーなどで形成されている。また、シール部材５０は、笠木２０の端面と笠木取付部１０Ｂの内底部３９との間で押し潰されて、笠木２０の端面と内底部３９との隙間を密閉している。なお、笠木２０及び笠木取付部１０Ｂは、被覆材２２の端面がシール部材５０を介して着座面３５に対向し、芯材２１の端面がシール部材５０を介して連結リブ３６の端面に対向するように形成されている。 As shown in FIGS. 4 and 5, a sealing member 50 made of an annular elastic body is disposed in the fitting recess 33 so as to be inserted through the inner cylindrical portion 32 and abut on the inner bottom portion 39. The seal member 50 is formed of an elastic synthetic resin, an elastomer, or the like. In addition, the seal member 50 is crushed between the end surface of the heddle 20 and the inner bottom 39 of the heddle mounting portion 10B, and seals the gap between the end surface of the heddle 20 and the inner bottom 39. In addition, in the cap 20 and the cap mounting portion 10B, the end face of the covering material 22 faces the seating face 35 via the seal member 50, and the end face of the core 21 faces the end face of the connecting rib 36 via the seal member 50. It is formed as follows.

ここで、内筒部３２の外周面には、内筒部３２の軸方向略全長に渡って伸びるガイドリブ３７が、内筒部３２の周方向等間隔に複数（実施形態では図３に示すように８個）形成されている。このガイドリブ３７は、前記連結リブ３６と同一位置となるようにされて、連結リブ３６に連なっている。これにより、内筒部３２を挿通されたシール部材５０が、ガイドリブ３７に案内されて逃げ溝３４の奥に入り込むことを防止できる。このガイドリブ３７の内筒部３２外周面からの突出高さは、連結リブ３６の長さ（内筒部３２の径方向における長さ）よりも小さくされている。なお、図５において、ガイドリブ３７を一点鎖線でもって示してある。 Here, on the outer peripheral surface of the inner cylindrical portion 32, a plurality of guide ribs 37 extending over substantially the entire axial length of the inner cylindrical portion 32 are provided at equal intervals in the circumferential direction of the inner cylindrical portion 32 (in the embodiment, as shown in FIG. 3). 8) are formed. The guide rib 37 is located at the same position as the connection rib 36 and is continuous with the connection rib 36. Thereby, the seal member 50 inserted through the inner cylindrical portion 32 can be prevented from being guided by the guide rib 37 and entering the depth of the escape groove 34. The projecting height of the guide rib 37 from the outer peripheral surface of the inner cylindrical portion 32 is smaller than the length of the connecting rib 36 (the length of the inner cylindrical portion 32 in the radial direction). In FIG. 5, the guide ribs 37 are indicated by alternate long and short dash lines.

ここで、内筒部３２の外周には、先端に向かうにつれて先細となるように、僅かな勾配が形成されている。すなわち、内筒部３２は、その外径が、先端（図４、図５左方側）に向かうにつれて徐々に小さくなるようにされている。これにより、後述する取付ブラケット１０に対する笠木２０の取付けにおいて、取付孔２４の穿孔位置を罫書くために一旦笠木取付部１０Ｂの嵌合凹部３４に挿嵌された笠木２０を、笠木取付部１０Ｂの嵌合凹部３４から引き抜き易くなる。 Here, a slight gradient is formed on the outer periphery of the inner cylindrical portion 32 so as to taper toward the distal end. That is, the outer diameter of the inner cylindrical portion 32 is gradually reduced toward the front end (the left side in FIGS. 4 and 5). Accordingly, in attaching the shed 20 to the mounting bracket 10, which will be described later, the shed 20 once inserted into the fitting concave portion 34 of the shed attachment portion 10 </ b> B in order to score the position of the perforation of the attachment hole 24. It becomes easy to pull out from the fitting recess 34.

一方、ガイドリブ３７は、内筒部３２の外周面の勾配を補償するように、内筒部３２の先端に向かうにつれて、内筒部３２の外周面からの突出高さが徐々に高くなるように形成されている。すなわち、ガイドリブ３７は、その全長に渡って、内筒部３２の軸心からの径方向距離が等しくなるようにされている。すなわち、複数のガイドリブ３７の高さ位置を周方向に滑らかに結んだ円形の仮想外周線α（図３参照）の直径が、ガイドリブ３７の全長に渡って等しくなるようにされている。そして、この仮想外周線αの外径が、芯材２１の内径と同一又は僅かに小さく設定されている。 On the other hand, the guide rib 37 compensates for the gradient of the outer peripheral surface of the inner cylindrical portion 32 so that the height of the protrusion from the outer peripheral surface of the inner cylindrical portion 32 gradually increases toward the tip of the inner cylindrical portion 32. Is formed. That is, the guide rib 37 is configured so that the radial distance from the axis of the inner cylindrical portion 32 is equal over the entire length. That is, the diameter of the circular virtual outer peripheral line α (see FIG. 3) that smoothly connects the height positions of the plurality of guide ribs 37 in the circumferential direction is made equal over the entire length of the guide ribs 37. The outer diameter of the virtual outer peripheral line α is set to be the same as or slightly smaller than the inner diameter of the core material 21.

上記のように内筒部３２の外周面及びガイドリブ３７を形成することにより、内筒部３２の芯材２１に対する接触面積を低減して、芯材２１が内筒部３２に対してより容易に嵌合されることとなる。すなわち、芯材２１が内筒部３２に対して若干芯ずれしたり斜めから嵌合されようとした際に、ガイドリブ３７が比較的容易に弾性変形して、芯材２１を内筒部３２に対してスムーズに嵌合されるようにガイドする。 By forming the outer peripheral surface of the inner cylindrical portion 32 and the guide ribs 37 as described above, the contact area of the inner cylindrical portion 32 with the core 21 is reduced, so that the core 21 can more easily contact the inner cylindrical portion 32. It will be fitted. That is, when the core 21 is slightly misaligned with respect to the inner cylindrical portion 32 or is about to be fitted obliquely, the guide rib 37 is relatively easily elastically deformed, and the core 21 is attached to the inner cylindrical portion 32. Guide them so that they fit smoothly.

以上のような構成において、取付ブラケット１０に対する笠木２０を取付ける手順について説明する。 A procedure for attaching the coping 20 to the mounting bracket 10 in the above configuration will be described.

まず、笠木１０が所望長さよりも長尺である場合に、手摺りの取付現場において切断工具によって所望長さに切断される。芯材２１がアルミニウム系金属で形成されており、鉄系金属に比してはるかに柔らかいために、高速切断機や電動のこぎり等の電動工具や金鋸等の手工具でも容易かつすみやかに笠木２０を切断することができ、また、電動工具で笠木２０を切断する際に火花が飛び散らないため、笠木２０の被覆材２２や取付現場の壁面・床面などが焼損することを防止できる。 First, when the cap 10 is longer than the desired length, the handrail is cut to a desired length by a cutting tool at the installation site of the handrail. Since the core material 21 is formed of an aluminum-based metal and is much softer than an iron-based metal, it can be easily and promptly used even with a high-speed cutting machine, an electric tool such as an electric saw, or a hand tool such as a metal saw. Can be cut, and sparks are not scattered when cutting the coping 20 with the electric tool, so that the covering material 22 of the coping 20 and the wall surface / floor surface at the installation site can be prevented from burning out.

笠木２０の所望長さが所定以上であるときは、補強パイプ２３が芯材２１内に挿入される。この補強パイプ２３も、必要に応じて、笠木２０よりも所定分短かい長さに、手すりＴの取付現場で用いられる切断工具で切断される。また、取付ブラケット１０には、予め工場でシール部材５０が笠木取付部１０Ｂの嵌合凹部３４内に挿入されて、接着材によって着座面３５（内底部３９）に接着されており、取付現場でのシール部材５０の取付忘れや取付作業の簡略化を図っている。 When the desired length of the cap 20 is equal to or longer than a predetermined length, the reinforcing pipe 23 is inserted into the core 21. This reinforcing pipe 23 is also cut by a cutting tool used at the site where the handrail T is attached, if necessary, to a length shorter than the coping 20 by a predetermined length. In the mounting bracket 10, a sealing member 50 is previously inserted into the fitting concave portion 34 of the hedder mounting portion 10B at the factory, and is bonded to the seating surface 35 (the inner bottom portion 39) with an adhesive. In this case, the user forgets to attach the seal member 50 and simplifies the attachment operation.

次に、笠木２０の端部を笠木取付部１０Ｂの嵌合凹部３４に挿入、嵌合させる。まず、
芯材２１の先端開口に内筒部３２を挿入させていき、この内筒部３２をガイドとしつつ笠木２０を外筒部３１内に挿入させていく。そして、笠木２０が嵌合凹部３４内に進入して笠木２０の取付孔２４が内筒部３２のねじ孔４１と重なり始める位置付近に達する辺りから、笠木２０の端面がシール部材５０を内底部３９の着座面３５や連結リブ３６の端面へ押圧し始める。さらに、笠木２０の取付孔２４が内筒部３２のねじ孔４１に整合する位置まで笠木２０が嵌合凹部３４内に進入すると、シール部材５０の外周側の部位が、笠木２０の被覆材２２の端面と内底部３９の着座面３５とにより押し潰され、シール部材５０の内周側の部位が、笠木２０の芯材２１の端面と連結リブ３６の端面とにより押し潰されて、これらの隙間が密閉される。すなわち、水が笠木２０の外周面と外筒部３１の内周面との隙間から嵌合凹部３４内に浸入しても、シール部材５０により水のこれ以上の浸入が阻止されるため、特に芯材２１の腐食が防止されることになる。また、取付現場で切断した笠木２０の端部に芯材２１のバリが生じても、笠木２０の端面によってシール部材５０が内底部３９に押圧される際、芯材２１のバリに押圧されたシール部材５０が逃げ溝３４内に撓むため、芯材２１のバリによるバラツキを吸収することができる。 Next, the end of the cap 20 is inserted and fitted into the fitting recess 34 of the cap mounting portion 10B. First,
The inner cylindrical portion 32 is inserted into the opening at the distal end of the core material 21, and the cap 20 is inserted into the outer cylindrical portion 31 while using the inner cylindrical portion 32 as a guide. Then, from around the position where the cap 20 enters the fitting recess 34 and the mounting hole 24 of the cap 20 starts to overlap with the screw hole 41 of the inner cylindrical portion 32, the end face of the cap 20 moves the seal member 50 to the inner bottom portion. It starts to press against the seating surface 35 of 39 and the end surface of the connecting rib 36. Further, when the heddle 20 enters the fitting recess 34 to a position where the mounting hole 24 of the heddle 20 is aligned with the screw hole 41 of the inner cylindrical part 32, the outer peripheral portion of the sealing member 50 is Of the seal member 50 and the end surface of the core member 21 of the coping 20 and the end surface of the connecting rib 36 are crushed by the end surface of the inner bottom portion 39 and the seating surface 35 of the inner bottom portion 39. The gap is closed. That is, even if water intrudes into the fitting recess 34 from the gap between the outer peripheral surface of the cap 20 and the inner peripheral surface of the outer cylindrical portion 31, the water is prevented from further entering by the seal member 50, Corrosion of the core 21 is prevented. Further, even if burrs of the core 21 occur at the end of the cap 20 cut at the installation site, when the seal member 50 is pressed against the inner bottom 39 by the end face of the support 20, the burrs of the core 21 are pressed. Since the seal member 50 bends into the escape groove 34, it is possible to absorb variations due to burrs of the core material 21.

このように笠木２０の端部を笠木取付部１０Ｂの嵌合凹部３４に挿嵌させた状態で、取付孔２４を穿孔する位置に罫書きを施し、笠木取付部１０Ｂから笠木２０を引き抜いて、笠木２０の罫書いた位置に取付孔２４を穿孔する。そして、再び笠木２０の端部を笠木取付部１０Ｂの嵌合凹部３４に挿嵌させた後、外筒部３１の挿入孔４２に挿入した固定ねじ４３を笠木２０の取付孔２４及び内筒部３２のねじ孔４１にねじ込むことにより、笠木取付部１０Ｂからの笠木２０の抜けが防止されると共に、笠木取付部１０Ｂに対する笠木２０の回り止めが行われて、シール部材５０により笠木２０の端面と内底部３９との隙間が密閉される。そして、外筒部３１の挿入孔４２に対して、目隠し用のカバー部材４４が嵌合形式で固定される。なお、カバー部材４４に代えて、目隠し用の充填材を外筒部３１の挿入孔４２に充填するようにしてもよい。 With the end of the cap 20 inserted into the fitting recess 34 of the cap mounting portion 10B in this way, scribing is performed at a position where the mounting hole 24 is to be drilled, and the cap 20 is pulled out from the cap mounting portion 10B. A mounting hole 24 is formed in the scribing position of the cap 20. Then, after the end of the cap 20 is again inserted into the fitting concave portion 34 of the cap mounting portion 10B, the fixing screw 43 inserted into the insertion hole 42 of the outer tube 31 is attached to the mounting hole 24 of the cap 20 and the inner tube. By screwing into the screw hole 41 of the cap 32, the cap 20 is prevented from coming off from the cap mounting portion 10B, and the cap 20 is prevented from rotating with respect to the cap mounting portion 10B. The gap with the inner bottom 39 is sealed. Then, a cover member 44 for blindfolding is fixed to the insertion hole 42 of the outer cylindrical portion 31 in a fitting manner. Note that, instead of the cover member 44, a filler for blindfold may be filled in the insertion hole 42 of the outer cylindrical portion 31.

なお、手すりＴは、笠木２０を取付ブラケット１０に取付けた後に、該取付ブラケット１０を取付面１に固定してもよく、あるいは、取付ブラケット１０を取付面１に固定した後に、該取付ブラケット１０に笠木２０を取付けてもよい。また、工場にて予めシール部材５０を取付ブラケット１０の内底部３９に設けておいたが、取付現場にてシール部材５０を取付ブラケット１０の内底部３９に設けることも可能である。また、取付現場にて笠木２０の端面にシール部材５０を接着し、該笠木２０の端部を笠木取付部１０Ｂの嵌合凹部３４に挿嵌させることも可能である。 Note that the handrail T may be fixed to the mounting surface 1 after attaching the cap 20 to the mounting bracket 10, or the mounting bracket 10 may be fixed to the mounting surface 1 after the mounting bracket 10 is fixed to the mounting surface 1. Kasagi 20 may be attached to the vehicle. Further, although the seal member 50 is provided in the inner bottom 39 of the mounting bracket 10 in advance at the factory, the seal member 50 may be provided in the inner bottom 39 of the mounting bracket 10 at the mounting site. Further, it is also possible to attach the seal member 50 to the end surface of the cap 20 at the mounting site, and insert the end of the cap 20 into the fitting concave portion 34 of the cap mounting portion 10B.

なお、本発明は、上述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲における変形及び改良を含むものである。上述の実施形態では、１つの笠木取付部１０Ｂを有するエルボ状の取付ブラケット１０を用いているが、例えば、２つの笠木取付部を有するＬ型の取付ブラケットや、３つの笠木取付部を有するＴ型の取付ブラケットなど、１または複数の笠木取付部を有する取付ブラケットとすることができる。また、上述の実施形態では、取付ブラケット１０に連結リブ３６及びガイドリブ３７をそれぞれ８個設けたが、７個以下または９個以上など複数個設けてあればよいが、少なくとも３個設けることが好ましい。また、上述の実施形態では、笠木２０を単層の被覆材２２で被覆したが、重層の被覆材で被覆してもよい。上述の実施形態では、シール部材５０が円環状に形成されているが、本発明はこれに限られず、笠木取付部の嵌合凹部に嵌合可能な環状に形成されて、笠木２０の端面と笠木取付部１０Ｂの内底部３９との間で押し潰されて隙間を密閉できる形状であればよい。また、本発明に係る手すりは、取付面として、例えば、浴室、トイレ、玄関、廊下等、建物の様々な壁面や、建物に設けられた扉等の設置物に取り付けることができる。なお、本発明に係る手すりでは、笠木取付部１０Ｂの内底部３９に逃げ溝３４及び連結リブ３６を設けず、外筒部３１の内周面より段状に縮径された着座面３５を内筒部３２の外周面まで延設することも可能だが、上述の実施形態のように笠木取付部１０Ｂの内底部３９に逃げ溝３４及び連結リブ３６を設けることが好ましい。 The present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved. In the above-described embodiment, the elbow-shaped mounting bracket 10 having one hedder mounting portion 10B is used. For example, an L-shaped mounting bracket having two hedder mounting portions or a T-shape having three hedder mounting portions is used. It can be a mounting bracket having one or a plurality of coping mounting parts, such as a mold mounting bracket. Further, in the above-described embodiment, the connection bracket 36 and the guide rib 37 are provided eight each in the mounting bracket 10, but it is sufficient that a plurality such as seven or less or nine or more is provided, but it is preferable to provide at least three. . In the above-described embodiment, the cap 20 is covered with the single-layer covering material 22, but may be covered with a multi-layer covering material.
