しかしながら、特許文献１に記載の手摺にあっては、予め手摺桿にネジ挿通孔を適切な位置にあける必要があり、そのネジ挿通孔をあける作業に手間がかかるといった問題があった。また、上述のような手摺においては、手摺桿の空洞に手摺桿受け部の挿嵌部を嵌合させた状態で、手摺桿に対して径方向にネジを貫通させて、このネジを手摺桿受け部の挿嵌部に螺合させることから、手摺桿受け部の小型化が困難であった。
また、特許文献１に記載の手摺は、手摺桿受け部の開口孔からネジの頭部が外部に露出しており、使用者が手摺を握った際に使用者の指がネジの頭部に触れてしまうといった問題があった。さらに、この問題を解消すべく、ネジの頭部を隠す保護キャップを手摺桿受け部の開口孔に取り付けることもあり、部品点数の増加や組立ての手間に繋がるという問題があった。
本発明の目的は、製造や組立てが容易であり、且つ手摺桿受け部の小型化が可能であり、且つ使用感が良好な手摺を提供することにある。 However, in the handrail described in Patent Document 1, it is necessary to make a screw insertion hole in an appropriate position in advance on the handrail rod, and there is a problem that it takes time and effort to make the screw insertion hole. Further, in the handrail as described above, in a state where the insertion portion of the handrail rod receiving portion is fitted in the cavity of the handrail rod, a screw is passed through the handrail rod in the radial direction, and this screw is passed through the handrail rod. It was difficult to reduce the size of the handrail rod receiving portion because it was screwed into the fitting portion of the receiving portion.
Further, in the handrail described in Patent Document 1, the head of the screw is exposed to the outside from the opening hole of the handrail rod receiving portion, and when the user grips the handrail, the user's finger touches the head of the screw. There was a problem of touching it. Further, in order to solve this problem, a protective cap that hides the head of the screw may be attached to the opening hole of the handrail rod receiving portion, which causes an increase in the number of parts and a problem that it takes time to assemble.
An object of the present invention is to provide a handrail that is easy to manufacture and assemble, can reduce the size of the handrail rod receiving portion, and has a good usability.

上記の目的を達成するために、本発明の第１の特徴は、パイプ状の手摺桿と、前記手摺桿を支持固定するブラケットとを備えた手摺であって、前記ブラケットは、前記手摺桿の端部が挿嵌される有底筒状の手摺桿受け部が備えられ、前記手摺桿の端部は、前記手摺桿受け部の底部に当接し、前記手摺桿の内周面には、長手方向に連続する複数のビスホールが突設され、前記手摺桿受け部の底部には、前記ビスホールに対応する位置にそれぞれネジ挿通孔が設けられ、各前記ネジ挿通孔を介して各前記ビスホールに螺合された複数のネジにより、前記手摺桿が前記ブラケットに固定されることにある。
これにより、手摺桿とブラケットをネジで固定する際に、従来の手摺のような手摺桿にネジ挿通孔をあける必要がなく、製造や組立てが容易である。また、第１の特徴によれば、手摺桿受け部に手摺桿の端部を挿嵌させた状態で、手摺桿受け部の底部のネジ挿通孔に裏面側からネジを貫通させて、このネジを手摺桿のビスホールに螺合させることから、従来の手摺よりも手摺桿受け部を小型化することができる。さらに、手摺桿受け部の底部の裏面にネジの頭部を配置したことにより、ブラケット内にネジの頭部を隠すことが容易となり、使用者がネジの頭部に触れないようにすることができる。 In order to achieve the above object, the first feature of the present invention is a handrail provided with a pipe-shaped handrail rod and a bracket for supporting and fixing the handrail rod, wherein the bracket is of the handrail rod. A bottomed tubular handrail rod receiving portion into which an end portion is inserted is provided, and the end portion of the handrail rod abuts on the bottom portion of the handrail rod receiving portion, and the inner peripheral surface of the handrail rod has a length. A plurality of screw holes continuous in the direction are projected, and screw insertion holes are provided at positions corresponding to the screw holes at the bottom of the handrail rod receiving portion, and the screw holes are screwed into the screw holes through the screw insertion holes. The handrail rod is fixed to the bracket by a plurality of combined screws.
As a result, when fixing the handrail rod and the bracket with screws, it is not necessary to make a screw insertion hole in the handrail rod as in the conventional handrail, and it is easy to manufacture and assemble. Further, according to the first feature, in a state where the end of the handrail rod is inserted into the handrail rod receiving portion, the screw is passed through the screw insertion hole at the bottom of the handrail rod receiving portion from the back surface side, and this screw is used. Is screwed into the screw hole of the handrail rod, so that the handrail rod receiving portion can be made smaller than the conventional handrail. Furthermore, by arranging the screw head on the back surface of the bottom of the handrail rod receiving part, it is easy to hide the screw head in the bracket and prevent the user from touching the screw head. can.

本発明の第２の特徴は、上記第１の特徴に加えて、前記手摺桿受け部の内面と前記手摺桿の端部には、前記手摺桿受け部において前記ビスホールの中空を前記ネジ挿通孔と対向するように前記手摺桿を周方向に位置決めする位置決め手段が設けられていることにある。
これにより、手摺桿受け部における手摺桿の位置決めが位置決め手段によって可能となり、手摺桿とブラケットとを適正な位置で固定でき、また、ネジを底部のネジ挿通孔に挿通してビスホールに螺合させる作業が容易になる。 The second feature of the present invention is that, in addition to the first feature, the hollow of the screw hole in the handrail rod receiving portion is formed into the screw insertion hole in the inner surface of the handrail rod receiving portion and the end portion of the handrail rod. A positioning means for positioning the handrail rod in the circumferential direction is provided so as to face the handrail rod.
As a result, the handrail rod can be positioned at the handrail rod receiving portion by the positioning means, the handrail rod and the bracket can be fixed at an appropriate position, and the screw is inserted into the screw insertion hole at the bottom and screwed into the screw hole. Work becomes easier.

本発明の第３の特徴は、上記第２の特徴に加えて、前記位置決め手段は、前記ビスホールの端部と、前記手摺桿受け部の底部内面に設けられた位置決め突起とで構成され、前記ビスホールの端部が前記位置決め突起に係合した場合に、前記ビスホールの中空が前記ネジ挿通孔と対向するように形成されたことにある。
これにより、ビスホール自体を手摺桿の位置決めに用いることができ、位置決め手段の構成として別途位置決め突起のみ設ければよく、位置決め手段を簡易な構成で形成することができる。 The third feature of the present invention is that, in addition to the second feature, the positioning means is composed of an end portion of the screw hole and a positioning protrusion provided on the inner surface of the bottom portion of the handrail rod receiving portion. When the end portion of the screw hole is engaged with the positioning protrusion, the hollow portion of the screw hole is formed so as to face the screw insertion hole.
As a result, the screw hole itself can be used for positioning the handrail rod, and only the positioning protrusion needs to be separately provided as the configuration of the positioning means, and the positioning means can be formed with a simple configuration.

本発明の第４の特徴は、上記第２の特徴に加えて、前記位置決め手段は、前記手摺桿の本体端部に設けられた位置決め凹部と、前記手摺桿受け部の内面における前記底部側の位置に設けられた位置決め凸部とで構成され、前記位置決め凹部が前記位置決め凸部に係合した場合に、前記ビスホールの中空が前記ネジ挿通孔と対向するように形成されたことにある。
これにより、手摺桿を手摺桿受け部内に挿入した後でも、手摺桿を周方向に回転させることで、位置決め凸部に位置決め凹部を適切に係合できるため、手摺桿受け部における手摺桿の位置決めが容易となる。 The fourth feature of the present invention is that, in addition to the second feature, the positioning means has a positioning recess provided at the end of the main body of the handrail rod and the bottom side of the inner surface of the handrail rod receiving portion. It is composed of a positioning convex portion provided at a position, and when the positioning concave portion engages with the positioning convex portion, the hollow of the screw hole is formed so as to face the screw insertion hole.
As a result, even after the handrail rod is inserted into the handrail rod receiving portion, the positioning recess can be appropriately engaged with the positioning convex portion by rotating the handrail rod in the circumferential direction, so that the handrail rod can be positioned in the handrail rod receiving portion. Becomes easier.

ところで、手摺桿には、金属製のパイプ材の表面を合成樹脂製の被覆体で被覆したものが多く用いられている。そのような合成樹脂製の被覆体を備えた手摺桿として、チューブ状の被覆体の中空部を昇圧して被覆体を拡径させ、この拡径した被覆体の中空部に金属製のパイプ材を挿入した後、被覆体の中空部内の昇圧状態を解消し、被覆体を縮径させてパイプ材の表面に圧着させる手摺桿が知られている（例えば、特開２０１２―１１１０８３号公報参照。）。
このように製造された手摺桿においては、パイプ材と被覆体とが接着剤で接着されていないため、激しい気温の変化に伴いチューブ状の被覆体が長手方向に収縮した場合や、高気温下で手摺桿の端部に対し長手方向への過度の引っ張りが繰り返された場合に、手摺桿の端部において被覆体が縮んでパイプ材の表面が外部に露出してしまうおそれがあった。 By the way, as the handrail rod, a metal pipe material whose surface is coated with a synthetic resin coating is often used. As a handrail rod provided with such a synthetic resin covering body, the hollow portion of the tubular covering body is pressurized to expand the diameter of the covering body, and a metal pipe material is formed in the hollow portion of the expanded covering body. (For example, see Japanese Patent Application Laid-Open No. 2012-111083), which eliminates the pressure-pressing state in the hollow portion of the covering body and causes the covering body to be reduced in diameter and crimped to the surface of the pipe material. ).
In the handrail rod manufactured in this way, since the pipe material and the covering body are not adhered with an adhesive, the tubular covering body shrinks in the longitudinal direction due to a drastic change in temperature, or under high temperature. When excessive pulling in the longitudinal direction is repeated with respect to the end portion of the handrail rod, there is a possibility that the covering body shrinks at the end portion of the handrail rod and the surface of the pipe material is exposed to the outside.

そのような問題を解決するために、本発明の第５の特徴は、上記第１乃至第４の特徴のいずれか一に加えて、前記手摺桿は、金属製のパイプ材の表面を合成樹脂製の被覆体で被覆してなり、前記手摺桿には、前記被覆体の長手方向の縮みを防止するピンが設けられており、前記ピンは、前記ビスホールを避けて前記手摺桿を直径方向に貫通することにある。
これにより、手摺桿の端部における被覆体の縮みをピンで規制することができ、パイプ材の表面が外部に露出することを防止できる。 In order to solve such a problem, the fifth feature of the present invention is, in addition to any one of the first to fourth features, the handrail rod is made of a synthetic resin on the surface of a metal pipe material. The handrail rod is provided with a pin that prevents the coating body from shrinking in the longitudinal direction, and the pin avoids the screw hole and makes the handrail rod in the radial direction. To penetrate.
As a result, the shrinkage of the covering body at the end of the handrail rod can be regulated by a pin, and the surface of the pipe material can be prevented from being exposed to the outside.

本発明の第６の特徴は、上記第５の特徴に加えて、前記ピンは、前記手摺桿における前記手摺桿受け部に挿嵌される部位に設けられたことにある。これにより、ピンは手摺桿受け部に隠れて外部に露出しない。 A sixth aspect of the present invention, in addition to the features of the upper Symbol fifth, the pin is that provided at a portion to be fitted into the handrail rod receiving portion of the handrail rods. As a result, the pin is hidden behind the handrail rod receiving portion and is not exposed to the outside.

本発明によれば、製造や組立てが容易であり、且つ手摺桿受け部の小型化が可能であり、且つ使用感が良好な手摺を提供することができる。 According to the present invention, it is possible to provide a handrail that is easy to manufacture and assemble, can reduce the size of the handrail rod receiving portion, and has a good usability.

以下、本発明に係る手摺を実施するための形態を、図面を参照して詳細に説明する。先ずは、本発明に係る手摺の第１例について、図１乃至図４を参照して説明する。
図１に示すように、第１例の手摺は、建物の便所、浴室、玄関等の壁面に据付けられる。また、第１例の手摺は、パイプ状の手摺桿１と、手摺桿１を支持固定するブラケット２とを備えている。 Hereinafter, a mode for carrying out the handrail according to the present invention will be described in detail with reference to the drawings. First, a first example of the handrail according to the present invention will be described with reference to FIGS. 1 to 4.
As shown in FIG. 1, the handrail of the first example is installed on the wall surface of the toilet, bathroom, entrance, etc. of the building. Further, the handrail of the first example includes a pipe-shaped handrail rod 1 and a bracket 2 for supporting and fixing the handrail rod 1.

図２に示すように、手摺桿１は、金属製のパイプ材３の表面を合成樹脂製の被覆体４で被覆したものである。被覆体４は、合成樹脂の押出成形によりパイプ材３と一体的に形成されている。 As shown in FIG. 2, the handrail rod 1 is obtained by coating the surface of a metal pipe material 3 with a covering body 4 made of a synthetic resin. The covering body 4 is integrally formed with the pipe material 3 by extrusion molding of a synthetic resin.

手摺桿１の内周面には、長手方向に連続する複数のビスホール５が突設されている。詳述すると、手摺桿１の内周面をなすパイプ材３は、長尺円筒状の部材であり、パイプ材３の内周面には、２つのビスホール５がパイプ材３の軸心に対して対称な位置に突設されている。パイプ材３とビスホール５とは、アルミニウム等の金属の押出成形によって一体成形されている。 A plurality of screw holes 5 continuous in the longitudinal direction are projected on the inner peripheral surface of the handrail rod 1. More specifically, the pipe material 3 forming the inner peripheral surface of the handrail rod 1 is a long cylindrical member, and two screw holes 5 are formed on the inner peripheral surface of the pipe material 3 with respect to the axial center of the pipe material 3. It is projected at a symmetrical position. The pipe material 3 and the screw hole 5 are integrally molded by extrusion molding of a metal such as aluminum.

ビスホール５の内部には、後述のネジ８を捩じ込み可能な中空７が形成されており、ビスホール５におけるパイプ材３の軸心側の部分には、長手方向に連続するスリット部６が形成されて、ビスホール５の断面が略Ｃ字状となっている。 Inside the screw hole 5, a hollow 7 into which a screw 8 described later can be screwed is formed, and a slit portion 6 continuous in the longitudinal direction is formed in a portion of the screw hole 5 on the axial side of the pipe material 3. Therefore, the cross section of the screw hole 5 is substantially C-shaped.

ブラケット２は、手摺桿受け部１１が設けられたブラケット本体９と、ブラケット本体９に着脱可能に装着されたブラケットカバー１０とを備えている。ブラケット本体９やブラケットカバー１０は、ＡＢＳ樹脂のような硬質合成樹脂によって成形されているものでもよいし、アルミ等の金属で成形されているものでもよい。
ブラケット本体９は、壁面に固定される壁面固定部１２と、壁面固定部１２から湾曲して延設された周壁部１３と、周壁部１３の先端部に設けられた有底筒状の手摺桿受け部１１とを備えている。なお、第１例では、ブラケット２の全体形状が概ねエルボ状に形成されているが、本発明は、手摺における手摺桿の本数や配置に応じてブラケットを適宜の全体形状とすることができる。 The bracket 2 includes a bracket main body 9 provided with a handrail rod receiving portion 11 and a bracket cover 10 detachably attached to the bracket main body 9. The bracket body 9 and the bracket cover 10 may be molded of a hard synthetic resin such as ABS resin, or may be molded of a metal such as aluminum.
The bracket main body 9 has a wall surface fixing portion 12 fixed to the wall surface, a peripheral wall portion 13 curved and extended from the wall surface fixing portion 12, and a bottomed tubular handrail rod provided at the tip end portion of the peripheral wall portion 13. It is provided with a receiving portion 11. In the first example, the overall shape of the bracket 2 is formed in a substantially elbow shape, but in the present invention, the bracket can be made into an appropriate overall shape according to the number and arrangement of the handrail rods in the handrail.

手摺桿受け部１１は、先端側を開口する略円筒状の筒壁部１４と、筒壁部１４の後端側を塞ぐ底部１５とを有する。手摺桿受け部１１の筒壁部１４の内部に手摺桿１の端部を挿嵌できるように、筒壁部１４の内径が手摺桿１の外径より僅かに大径となっている。また、手摺桿１の端部を筒壁部１４内に挿入していくと、手摺桿１の端部が底部１５の内面（表面）に当接するようになっている。 The handrail rod receiving portion 11 has a substantially cylindrical tubular wall portion 14 that opens the tip end side, and a bottom portion 15 that closes the rear end side of the tubular wall portion 14. The inner diameter of the cylinder wall portion 14 is slightly larger than the outer diameter of the handrail rod 1 so that the end portion of the handrail rod 1 can be inserted into the cylinder wall portion 14 of the handrail rod receiving portion 11. Further, when the end portion of the handrail rod 1 is inserted into the cylinder wall portion 14, the end portion of the handrail rod 1 comes into contact with the inner surface (surface) of the bottom portion 15.

手摺桿受け部１１の底部１５には、ビスホール５に対応する位置にそれぞれネジ挿通孔１６が貫通している。第１例では、２つのネジ挿通孔１６が筒壁部１４の軸心に対して左右対称な位置に形成されている。 A screw insertion hole 16 penetrates the bottom portion 15 of the handrail rod receiving portion 11 at a position corresponding to the screw hole 5. In the first example, the two screw insertion holes 16 are formed at positions symmetrical with respect to the axial center of the cylinder wall portion 14.

ネジ挿通孔１６は、ブラケット２に手摺桿１を固定するためのネジ８の軸部が挿通可能とされ、且つネジ８の頭部が挿通不可とされる。具体的には、ネジ挿通孔１６は、ネジ８の軸部８ａよりも大径に形成されると共に、ネジ８の頭部８ｂよりも小径に形成される。また、ネジ挿通孔１６は、ビスホール５の中空７よりも大径に形成にされる。 In the screw insertion hole 16, the shaft portion of the screw 8 for fixing the handrail rod 1 to the bracket 2 can be inserted, and the head portion of the screw 8 cannot be inserted. Specifically, the screw insertion hole 16 is formed to have a larger diameter than the shaft portion 8a of the screw 8 and a smaller diameter than the head portion 8b of the screw 8. Further, the screw insertion hole 16 is formed to have a larger diameter than the hollow 7 of the screw hole 5.

ブラケット本体９の壁面固定部１２には、図２に示すように、厚み方向に貫通する貫通孔１７が形成されている。壁面固定部１２は、この貫通孔１７を介してネジ等の固定手段１８によって壁面Ａに固定される。また、壁面固定部１２には、ブラケットカバー１０の係止凸部２２を係止する係止凹部１９が設けられている。 As shown in FIG. 2, the wall surface fixing portion 12 of the bracket main body 9 is formed with a through hole 17 penetrating in the thickness direction. The wall surface fixing portion 12 is fixed to the wall surface A by a fixing means 18 such as a screw through the through hole 17. Further, the wall surface fixing portion 12 is provided with a locking recess 19 for locking the locking convex portion 22 of the bracket cover 10.

ブラケット本体９の周壁部１３は、湾曲した略半円筒状に形成されて手摺桿受け部１１と壁面固定部１２とを接続し、周壁部１３の内側には、複数の補強リブ２１が設けられている。 The peripheral wall portion 13 of the bracket body 9 is formed in a substantially semi-cylindrical shape that is curved to connect the handrail rod receiving portion 11 and the wall surface fixing portion 12, and a plurality of reinforcing ribs 21 are provided inside the peripheral wall portion 13. ing.

ブラケットカバー１０は、手摺桿受け部１１の底部１５の裏面や周壁部１３の内側を隠すとともに、ブラケット２の外形の一部を成すものである。ブラケットカバー１０は、図４に示すように、湾曲した略半円筒状に形成されており、ブラケットカバー１０の内側には、ブラケット本体９の係止凹部１９に係止する係止凸部２２が設けられている。 The bracket cover 10 hides the back surface of the bottom portion 15 of the handrail rod receiving portion 11 and the inside of the peripheral wall portion 13, and forms a part of the outer shape of the bracket 2. As shown in FIG. 4, the bracket cover 10 is formed in a substantially semi-cylindrical shape that is curved, and inside the bracket cover 10, a locking protrusion 22 that locks into the locking recess 19 of the bracket body 9 is provided. It is provided.

次に、このように構成された第１例の手摺における、手摺桿１をブラケット２に固定する方法について説明する。
まず、ブラケットカバー１０を未装着のブラケット本体９に対し、手摺桿受け部１１内に手摺桿１の端部を挿入する。そして、手摺桿１の端部を手摺桿受け部１１の底部１５の内面に当接させるとともに、手摺桿受け部１１内で手摺桿１を周方向に回転させて、ビスホール５の中空７を底部１５のネジ挿通孔１６と対向させる。
この状態で、底部１５の各ネジ挿通孔１６に対し、それぞれネジ８（例えば、タッピンねじ）を手摺桿受け部１１の底部１５の外面側（裏面側）、つまり周壁部１３側から通し、さらにネジ８をビスホール５内に捩じ込んで螺合させる。このネジ止め作業により手摺桿１がブラケット２に強固に固定される。 Next, a method of fixing the handrail rod 1 to the bracket 2 in the handrail of the first example configured in this way will be described.
First, the end portion of the handrail rod 1 is inserted into the handrail rod receiving portion 11 with respect to the bracket body 9 to which the bracket cover 10 is not attached. Then, the end portion of the handrail rod 1 is brought into contact with the inner surface of the bottom portion 15 of the handrail rod receiving portion 11, and the handrail rod 1 is rotated in the circumferential direction in the handrail rod receiving portion 11 so that the hollow 7 of the screw hole 5 is bottomed. It faces the screw insertion hole 16 of 15.
In this state, a screw 8 (for example, a tapping screw) is passed through each screw insertion hole 16 of the bottom portion 15 from the outer surface side (back surface side) of the bottom portion 15 of the handrail rod receiving portion 11, that is, the peripheral wall portion 13 side, and further. The screw 8 is screwed into the screw hole 5 to be screwed. By this screwing work, the handrail rod 1 is firmly fixed to the bracket 2.

このような第１例の手摺によれば、手摺桿１をブラケット２に固定する際に、従来の手摺のような手摺桿にネジ挿通孔をあける必要がなく、製造や組立てが容易である。また、手摺桿１をブラケット２に固定する際、ネジ８を手摺桿受け部１１の底部１５のネジ挿通孔１６に挿通して手摺桿１のビスホール５に螺合させるため、従来の手摺よりも手摺桿受け部１１を小型化することができる。また、手摺桿１をブラケット２に固定するネジ８の頭部８ｂが、手摺桿受け部１１の底部１５の裏面に位置してブラケット２内に隠されるため、使用者がネジ８の頭部８ｂに触れることはなく、したがって、ネジ８の頭部８ｂを隠す保護キャップを設ける必要もない。 According to the handrail of the first example, when the handrail rod 1 is fixed to the bracket 2, it is not necessary to make a screw insertion hole in the handrail rod as in the conventional handrail, and it is easy to manufacture and assemble. Further, when fixing the handrail rod 1 to the bracket 2, the screw 8 is inserted into the screw insertion hole 16 at the bottom 15 of the handrail rod receiving portion 11 and screwed into the screw hole 5 of the handrail rod 1, so that the handrail is more than the conventional handrail. The handrail rod receiving portion 11 can be miniaturized. Further, since the head 8b of the screw 8 for fixing the handrail rod 1 to the bracket 2 is located on the back surface of the bottom portion 15 of the handrail rod receiving portion 11 and is hidden in the bracket 2, the user can hide the head 8b of the screw 8. Therefore, it is not necessary to provide a protective cap that hides the head 8b of the screw 8.

次に、本発明に係る手摺の第２例について、図５及び図６を参照して説明する。
第２例の手摺は、前記第１例と基本構成において変わるところがないため、以下、第１例と異なる部分を中心に説明することとし、第１例と同一の構成については同一の符号を付し、その詳細は第１例の説明を援用する。
第２例では、手摺桿受け部１１の内面と手摺桿１の端部には、手摺桿受け部１１において手摺桿１を周方向に位置決めする位置決め手段が設けられている。 Next, a second example of the handrail according to the present invention will be described with reference to FIGS. 5 and 6.
Since the handrail of the second example is the same as that of the first example in the basic configuration, the parts different from the first example will be mainly described below, and the same components as those of the first example are designated by the same reference numerals. However, the description of the first example is used for the details.
In the second example, the inner surface of the handrail rod receiving portion 11 and the end portion of the handrail rod 1 are provided with positioning means for positioning the handrail rod 1 in the circumferential direction in the handrail rod receiving portion 11.

第２例の位置決め手段２３Ａは、ビスホール５の端部と、手摺桿受け部１１の底部１５内面に設けられた位置決め突起２４とで構成されている。ビスホール５の端部が位置決め突起２４に係合した場合に、ビスホール５の中空７がネジ挿通孔１６と対向するように形成されており、これにより、底部１５のネジ挿通孔１６に挿入したネジ８をビスホール５内に捩じ込むことができる。 The positioning means 23A of the second example is composed of an end portion of the screw hole 5 and a positioning protrusion 24 provided on the inner surface of the bottom portion 15 of the handrail rod receiving portion 11. When the end of the screw hole 5 is engaged with the positioning protrusion 24, the hollow 7 of the screw hole 5 is formed so as to face the screw insertion hole 16, whereby the screw inserted into the screw insertion hole 16 of the bottom portion 15 is formed. 8 can be screwed into the screw hole 5.

位置決め突起２４は、図５に示すように、底部１５の内面に、ネジ挿通孔１６の周縁の底部１５中心側に沿った略半円弧状に形成されている。第２例では、底部１５の内面には、２つのネジ挿通孔１６の近傍にそれぞれ位置決め突起２４が突設されている。略半円弧状の位置決め突起２４の内側にビスホール５の端部が位置する場合、手摺桿１が手摺桿受け部１１内を周方向に回転しようとしても、ビスホール５の端部が位置決め突起２４に当接するため、手摺桿１の周方向の回転が規制されるようになっている。 As shown in FIG. 5, the positioning protrusion 24 is formed on the inner surface of the bottom portion 15 in a substantially semicircular shape along the center side of the bottom portion 15 on the peripheral edge of the screw insertion hole 16. In the second example, positioning protrusions 24 are provided on the inner surface of the bottom portion 15 in the vicinity of the two screw insertion holes 16, respectively. When the end of the screw hole 5 is located inside the substantially semicircular positioning protrusion 24, even if the handrail rod 1 tries to rotate in the handrail rod receiving portion 11 in the circumferential direction, the end of the screw hole 5 becomes the positioning protrusion 24. Since they come into contact with each other, the rotation of the handrail rod 1 in the circumferential direction is restricted.

なお、位置決め突起２４の底部１５内面からの突出高さは、本第２例では０．５ｍｍ〜２ｍｍ程度となっているが、これに限定されるものでなく、手摺桿１の周方向への回転に対してビスホール５の端部が位置決め突起２４に係止されればよい。 The height of the positioning protrusion 24 protruding from the inner surface of the bottom portion 15 is about 0.5 mm to 2 mm in the second example, but the height is not limited to this, and the height of the positioning protrusion 24 in the circumferential direction of the handrail rod 1 is not limited to this. The end of the screw hole 5 may be locked to the positioning protrusion 24 with respect to rotation.

このような構成による第２例の手摺によれば、図６に示すように、ビスホール５の端部を位置決め突起２４に係合させることにより、ビスホール５の中空７をネジ挿通孔１６と対向させた状態で手摺桿１を位置決めすることができる。これにより、手摺桿１とブラケット２とを適正な位置で固定でき、また、ネジ８を底部１５のネジ挿通孔１６に挿通してビスホール５に螺合させる作業が容易になる。
また、第２例の手摺によれば、ビスホール５自体を手摺桿１の位置決めに用いるため、位置決め手段２３Ａの構成として別途位置決め突起２４のみ設ければよく、位置決め手段２３Ａを簡易な構成で形成することができる。 According to the handrail of the second example having such a configuration, as shown in FIG. 6, the hollow 7 of the screw hole 5 is made to face the screw insertion hole 16 by engaging the end portion of the screw hole 5 with the positioning protrusion 24. The handrail rod 1 can be positioned in this state. As a result, the handrail rod 1 and the bracket 2 can be fixed at an appropriate position, and the work of inserting the screw 8 into the screw insertion hole 16 of the bottom 15 and screwing it into the screw hole 5 becomes easy.
Further, according to the handrail of the second example, since the screw hole 5 itself is used for positioning the handrail rod 1, only the positioning protrusion 24 may be separately provided as the configuration of the positioning means 23A, and the positioning means 23A is formed with a simple configuration. be able to.

次に、第２例の位置決め手段の変形例について、図７を参照して説明する。
変形例の位置決め手段２３Ｂは、ビスホール５の端部と、手摺桿受け部１１の底部１５内面に設けられた位置決め突起２４と、ビスホール５の端部を位置決め突起２４に誘導する誘導突起２５とで構成されている。 Next, a modified example of the positioning means of the second example will be described with reference to FIG. 7.
The positioning means 23B of the modified example includes an end portion of the screw hole 5, a positioning protrusion 24 provided on the inner surface of the bottom portion 15 of the handrail rod receiving portion 11, and a guide protrusion 25 for guiding the end portion of the screw hole 5 to the positioning protrusion 24. It is configured.

誘導突起２５は、図７に示すように、手摺桿受け部１１の底部１５内面において、位置決め突起２４の直上の位置と直下の位置とにそれぞれ設けられている。誘導突起２５は、２つの位置決め突起２４の端部同士を接続する円弧状に形成されている。誘導突起２５は、手摺桿１が手摺桿受け部１１内を周方向に回転した際のビスホール５の端部の軌跡に沿った円弧状に形成されている。したがって、手摺桿１が手摺桿受け部１１内に挿入された場合に、ビスホール５の端部が位置決め突起２４から外れていたとき、ビスホール５の端部が誘導突起２５に当接するようになっている。 As shown in FIG. 7, the guide protrusions 25 are provided at positions directly above and directly below the positioning protrusions 24 on the inner surface of the bottom portion 15 of the handrail rod receiving portion 11. The guide protrusion 25 is formed in an arc shape that connects the ends of the two positioning protrusions 24 to each other. The guide protrusion 25 is formed in an arc shape along the locus of the end portion of the screw hole 5 when the handrail rod 1 rotates in the handrail rod receiving portion 11 in the circumferential direction. Therefore, when the handrail rod 1 is inserted into the handrail rod receiving portion 11, when the end portion of the screw hole 5 is separated from the positioning protrusion 24, the end portion of the screw hole 5 comes into contact with the guide protrusion 25. There is.

このような構成による変形例の手摺では、手摺桿１を手摺桿受け部１１内に挿入した際にビスホール５の端部が位置決め突起２４から外れていても、手摺桿１を周方向に回転させていくと、ビスホール５の端部が誘導突起２５上を摺動し、やがてビスホール５の端部が位置決め突起２４内に嵌入し、手摺桿受け部１１における手摺桿１の位置決めがなされる。
なお、本変形例では、位置決め突起２４と誘導突起２５とを連続して形成したが、手摺桿１を周方向に回転させた際にビスホール５の端部が誘導突起２５上を摺動して位置決め突起２４内に嵌入できれば、位置決め突起２４と誘導突起２５とを分離して形成してもよい。 In the handrail of the modified example having such a configuration, even if the end of the screw hole 5 is disengaged from the positioning protrusion 24 when the handrail rod 1 is inserted into the handrail rod receiving portion 11, the handrail rod 1 is rotated in the circumferential direction. Then, the end portion of the screw hole 5 slides on the guide protrusion 25, and eventually the end portion of the screw hole 5 is fitted into the positioning protrusion 24, and the handrail rod 1 is positioned in the handrail rod receiving portion 11.
In this modification, the positioning protrusion 24 and the guide protrusion 25 are continuously formed, but when the handrail rod 1 is rotated in the circumferential direction, the end portion of the screw hole 5 slides on the guide protrusion 25. If it can be fitted into the positioning protrusion 24, the positioning protrusion 24 and the guide protrusion 25 may be formed separately.

上述した第２例では、ビスホール５とネジ挿通孔１６とが対向するように確認しながら、手摺桿１を手摺桿受け部１１内に挿入していくことで、ビスホール５の端部を位置決め突起２４に適切に係合できるようになっている。これに対し、本変形例では、手摺桿１を手摺桿受け部１１内に挿入した後でも、手摺桿１を周方向に回転させることで、ビスホール５の端部を位置決め突起２４に適切に係合できるため、手摺桿受け部１１における手摺桿１の位置決めが容易となる。 In the second example described above, the end of the screw hole 5 is positioned by inserting the handrail rod 1 into the handrail rod receiving portion 11 while confirming that the screw hole 5 and the screw insertion hole 16 face each other. It is designed so that it can be properly engaged with 24. On the other hand, in this modification, even after the handrail rod 1 is inserted into the handrail rod receiving portion 11, the end portion of the screw hole 5 is appropriately engaged with the positioning protrusion 24 by rotating the handrail rod 1 in the circumferential direction. Therefore, the handrail rod 1 can be easily positioned in the handrail rod receiving portion 11.

次に、本発明に係る手摺の第３例について、図８及び図９を参照して説明する。
第３例の手摺は、前記第１例と基本構成において変わるところがないため、以下、第１例と異なる部分を中心に説明することとし、第１例と同一の構成については同一の符号を付し、その詳細は第１例の説明を援用する。
第３例では、第２例とは異なる位置決め手段２３Ｃが設けられている。第３例の位置決め手段２３Ｃは、手摺桿１の端部に設けられた位置決め凹部２６と、手摺桿受け部１１の内面における底部１５側の位置に設けられた位置決め凸部２７とで構成されている。位置決め凹部２６が位置決め凸部２７に係合した場合に、ビスホール５の中空７がネジ挿通孔１６と対向するように形成されており、これにより、底部１５のネジ挿通孔１６に挿入したネジ８をビスホール５内に捩じ込むことができる。 Next, a third example of the handrail according to the present invention will be described with reference to FIGS. 8 and 9.
Since the handrail of the third example is the same as that of the first example in the basic configuration, the parts different from the first example will be mainly described below, and the same components as those of the first example are designated by the same reference numerals. However, the description of the first example is used for the details.
In the third example, a positioning means 23C different from that in the second example is provided. The positioning means 23C of the third example is composed of a positioning recess 26 provided at the end of the handrail rod 1 and a positioning convex portion 27 provided at a position on the inner surface of the handrail rod receiving portion 11 on the bottom 15 side. There is. When the positioning recess 26 engages with the positioning protrusion 27, the hollow 7 of the screw hole 5 is formed so as to face the screw insertion hole 16, whereby the screw 8 inserted into the screw insertion hole 16 of the bottom portion 15 is formed. Can be screwed into the screw hole 5.

手摺桿１の端部には、２つの位置決め凹部２６が手摺桿１の軸心に対して対称な位置に設けられている。本第３例では、図８に示すように、位置決め凹部２６は、手摺桿１においてビスホール５の突設された位置から周方向に９０°ずれた位置に形成されている。位置決め凹部２６は、手摺桿１の端面を略矩形状に切り欠いた形状となっている。 At the end of the handrail rod 1, two positioning recesses 26 are provided at positions symmetrical with respect to the axis of the handrail rod 1. In the third example, as shown in FIG. 8, the positioning recess 26 is formed at a position of the handrail rod 1 at a position deviated by 90 ° in the circumferential direction from the position where the screw hole 5 is projected. The positioning recess 26 has a shape in which the end surface of the handrail rod 1 is cut out in a substantially rectangular shape.

図９に示すように、手摺桿受け部１１の筒壁部１４内面には、２つの位置決め凸部２７が筒壁部１４の軸心に対して上下対称な位置に設けられている。位置決め凸部２７は、底部１５から手摺桿受け部１１の開口側に向けて筒壁部１４の軸心と平行に延びる四角柱状に形成されている。また、筒壁部１４内面から軸心へ向かう位置決め凸部２７の突出端が、手摺桿受け部１１内における少なくとも手摺桿１の外周面の位置を越えており、好ましくは手摺桿１の内周面の位置に達するように形成される。これにより、手摺桿１の端部を手摺桿受け部１１内に挿入する場合に、位置決め凹部２６が位置決め凸部２７に対して周方向に位置ずれしているとき、手摺桿１の端面が位置決め凸部２７の端面に当接して手摺桿受け部１１の底部１５に当接できない。さらに、位置決め凹部２６内に位置決め凸部２７を嵌入した場合に、手摺桿１を周方向へ回転させようとしても、位置決め凹部２６の周縁が位置決め凸部２７に当接し、手摺桿１の周方向への回転が妨げられる。なお、位置決め凹部２６内に位置決め凸部２７が嵌入した場合に手摺桿１の端面が手摺桿受け部１１の底部１５に当接できるように、位置決め凹部２６の深さが位置決め凸部２７の長さと同等以上に形成される。 As shown in FIG. 9, two positioning convex portions 27 are provided on the inner surface of the cylinder wall portion 14 of the handrail rod receiving portion 11 at positions symmetrical with respect to the axial center of the cylinder wall portion 14. The positioning convex portion 27 is formed in a square columnar shape extending from the bottom portion 15 toward the opening side of the handrail rod receiving portion 11 in parallel with the axial center of the tubular wall portion 14. Further, the protruding end of the positioning convex portion 27 from the inner surface of the cylinder wall portion 14 toward the axial center exceeds at least the position of the outer peripheral surface of the handrail rod 1 in the handrail rod receiving portion 11, and is preferably the inner circumference of the handrail rod 1. It is formed to reach the position of the surface. As a result, when the end portion of the handrail rod 1 is inserted into the handrail rod receiving portion 11, the end surface of the handrail rod 1 is positioned when the positioning recess 26 is displaced in the circumferential direction with respect to the positioning convex portion 27. It abuts on the end surface of the convex portion 27 and cannot abut on the bottom portion 15 of the handrail rod receiving portion 11. Further, when the positioning convex portion 27 is fitted in the positioning concave portion 26, even if the handrail rod 1 is to be rotated in the circumferential direction, the peripheral edge of the positioning concave portion 26 comes into contact with the positioning convex portion 27, and the handrail rod 1 is in the circumferential direction. Rotation to is hindered. The depth of the positioning recess 26 is the length of the positioning protrusion 27 so that the end surface of the handrail rod 1 can come into contact with the bottom 15 of the handrail rod receiving portion 11 when the positioning protrusion 27 is fitted into the positioning recess 26. Is formed equal to or better than.

このような構成による第３例の手摺では、手摺桿１の端部を手摺桿受け部１１内に挿入する場合に、位置決め凹部２６が位置決め凸部２７に対して周方向に位置ずれしていると、手摺桿１の端面が位置決め凸部２７の端面に当接するが、さらに手摺桿１を周方向に回転させていくと、手摺桿１の端面が位置決め凸部２７上を摺動し、やがて位置決め凹部２６内に位置決め凸部２７が嵌入する。これにより、ビスホール５の中空７がネジ挿通孔１６と対向するように、手摺桿受け部１１における手摺桿１の位置決めがなされる。 In the handrail of the third example having such a configuration, when the end portion of the handrail rod 1 is inserted into the handrail rod receiving portion 11, the positioning recess 26 is displaced in the circumferential direction with respect to the positioning convex portion 27. Then, the end face of the handrail rod 1 comes into contact with the end face of the positioning convex portion 27, but when the handrail rod 1 is further rotated in the circumferential direction, the end face of the handrail rod 1 slides on the positioning convex portion 27, and eventually. The positioning convex portion 27 fits into the positioning concave portion 26. As a result, the handrail rod 1 is positioned in the handrail rod receiving portion 11 so that the hollow 7 of the screw hole 5 faces the screw insertion hole 16.

このように、第３例の手摺によれば、手摺桿１を手摺桿受け部１１内に挿入した後でも、手摺桿１を周方向に回転させることで、位置決め凸部２７に位置決め凹部２６を適切に係合できるため、手摺桿受け部１１における手摺桿１の位置決めが容易となる。 As described above, according to the handrail of the third example, even after the handrail rod 1 is inserted into the handrail rod receiving portion 11, the positioning recess 26 is formed in the positioning convex portion 27 by rotating the handrail rod 1 in the circumferential direction. Since it can be properly engaged, the handrail rod 1 can be easily positioned in the handrail rod receiving portion 11.

次に、本発明に係る手摺の第４例について、図１０及び図１１を参照して説明する。
第４例の手摺は、前記第１例と基本構成において変わるところがないため、以下、第１例と異なる部分を中心に説明することとし、第１例と同一の構成については同一の符号を付し、その詳細は第１例の説明を援用する。
第１例の手摺桿１は、被覆体４を合成樹脂の押出成形によりパイプ材３と一体的に形成されているが、第４例の手摺桿２８は、被覆体２９として合成樹脂製チューブがパイプ材３０表面に圧着されている。 Next, a fourth example of the handrail according to the present invention will be described with reference to FIGS. 10 and 11.
Since the handrail of the fourth example is the same as that of the first example in the basic configuration, the parts different from the first example will be mainly described below, and the same components as those of the first example are designated by the same reference numerals. However, the description of the first example is used for the details.
In the handrail rod 1 of the first example, the covering body 4 is integrally formed with the pipe material 3 by extrusion molding of a synthetic resin, whereas in the handrail rod 28 of the fourth example, a synthetic resin tube is used as the covering body 29. It is crimped to the surface of the pipe material 30.

図１１に示すように、手摺桿２８には、被覆体２９の外周からパイプ材３０の内周にかけて厚み方向に貫通するピン挿通孔３１が設けられており、このピン挿通孔３１には、被覆体２９の長手方向の縮みを防止するピン３２が挿嵌されている。本第４例では、手摺桿２８を一の直径方向に沿って２つのピン挿通孔３１が貫通されて、１本のピン３２がこの２つのピン挿通孔３１に挿通されている。また、ピン挿通孔３１は、手摺桿２８においてビスホール５の突設された位置から周方向に９０°ずれた位置に形成されている。ピン３２は、パイプ材３０の外径寸法よりも長く、被覆体２９の外径寸法よりも短いものが用いられ、ピン３２の先端は、被覆体２９に開孔されたピン挿通孔３１内に配置されている。 As shown in FIG. 11, the handrail rod 28 is provided with a pin insertion hole 31 penetrating in the thickness direction from the outer circumference of the covering body 29 to the inner circumference of the pipe member 30, and the pin insertion hole 31 is covered. A pin 32 that prevents the body 29 from shrinking in the longitudinal direction is inserted. In the fourth example, the handrail rod 28 is penetrated through two pin insertion holes 31 along one diameter direction, and one pin 32 is inserted through the two pin insertion holes 31. Further, the pin insertion hole 31 is formed at a position of the handrail rod 28 at a position deviated by 90 ° in the circumferential direction from the position where the screw hole 5 is projected. The pin 32 used is longer than the outer diameter dimension of the pipe material 30 and shorter than the outer diameter dimension of the covering body 29, and the tip of the pin 32 is inside the pin insertion hole 31 formed in the covering body 29. Have been placed.

ピン挿通孔３１及びピン３２は、図１０に示すように、手摺桿２８における手摺桿受け部１１内に挿嵌される部分に設けられている。これにより、ピン挿通孔３１及びピン３２が手摺桿受け部１１内に隠れて外部に露出せず、使用者がピン３２に触れないようになっている。 As shown in FIG. 10, the pin insertion hole 31 and the pin 32 are provided in a portion of the handrail rod 28 to be inserted into the handrail rod receiving portion 11. As a result, the pin insertion hole 31 and the pin 32 are hidden inside the handrail rod receiving portion 11 and are not exposed to the outside, so that the user does not touch the pin 32.

このように構成された第４例の手摺によれば、手摺桿２８の端部における被覆体２９の縮みをピン３２で規制することができ、パイプ材３０の表面が外部に露出することを防止できる。
なお、第４例の手摺に上述の第２例の位置決め手段２３Ａ、変形例の位置決め手段２３Ｂ又は第３例の位置決め手段２３Ｃを適用してもよい。 According to the handrail of the fourth example configured in this way, the shrinkage of the covering body 29 at the end of the handrail rod 28 can be regulated by the pin 32, and the surface of the pipe material 30 is prevented from being exposed to the outside. can.
The positioning means 23A of the second example, the positioning means 23B of the modified example, or the positioning means 23C of the third example may be applied to the handrail of the fourth example.
