支持部９の側部には凹部１２が形成されている。この凹部１２は、支持部９の各側部に形成されて対となっている。
前記支持部９はタッピングねじ等のねじ部材３を介して手摺りバー２を支持している。この支持部９において、固定部１０が形成された側とは反対側の面が手摺りバー２の端部が当接される当接面９ｃとなっており、ねじ部材３は支持部９の孔１１に挿通されて前記当接面９ｃに当接した手摺りバー２の螺合部６（溝６ｂ）にねじ込まれている。螺合部６の溝６ｂの径は、ねじ部材３の軸径よりもやや小さくされており、溝６ｂにねじ部材３がねじ込まれることによって、手摺りバー２と支持部材４とが強固に連結されることになる。 A concave portion 12 is formed on the side portion of the support portion 9. The concave portion 12 is formed on each side portion of the support portion 9 to form a pair.
The support portion 9 supports the handrail bar 2 via a screw member 3 such as a tapping screw. In this support portion 9, the surface opposite to the side on which the fixing portion 10 is formed is an abutting surface 9 c with which the end portion of the handrail bar 2 abuts. It is screwed into the threaded portion 6 (groove 6b) of the handrail bar 2 inserted through the hole 11 and in contact with the contact surface 9c. Diameter of the groove 6b of the engagement portion 6 is slightly smaller than the shaft diameter of the screw member 3 by the screw member 3 is screwed into the groove 6 b, and is firmly handrail bars 2 and the support member 4 Will be linked.

前記固定部１０は、支持部９に対して約９０°の角度で屈曲して形成されている。この固定部１０には、複数（図例では３つ）の孔１４が板厚方向（上下方向）に貫通して形成されている。固定部１０は、取付面Ａに当接され、前記孔１４を通じてねじ部材等の固定手段（例えばねじ部材）１３によって取付面Ａに固定されている。
外カバー部材１５は、合成樹脂製で、支持部材４に取り付けた時に、ねじ部材３および前記固定手段１３を目隠しするようになっている。この外カバー部材１５は、手摺りバー２に対してその正面側が開口状とされ、その背面側に支持部９とほぼ相似な背壁部１７が設けられている。この背壁部１７の周縁には手摺りバー２に向かって突出する側壁部１８が形成されている。 The fixed portion 10 is formed to be bent at an angle of about 90 ° with respect to the support portion 9. A plurality (three in the illustrated example) of holes 14 are formed in the fixing portion 10 so as to penetrate in the plate thickness direction (vertical direction). The fixing portion 10 is in contact with the mounting surface A, and is fixed to the mounting surface A through fixing holes 13 such as screw members (for example, screw members) through the holes 14.
The outer cover member 15 is made of synthetic resin, and blinds the screw member 3 and the fixing means 13 when attached to the support member 4. The outer cover member 15 has an opening on the front side with respect to the handrail bar 2, and a back wall portion 17 substantially similar to the support portion 9 is provided on the rear side. A side wall 18 that protrudes toward the handrail bar 2 is formed on the periphery of the back wall 17.

背壁部１７は、その基部１７ａ側から先端部１７ｂに向かって先細り状（または、先端部１７ｂ側から基部１７ａに向かって末広がり状）に形成されており、その先端部１７ｂが円形状に形成されている。したがって、前記側壁部１８も前記背壁部１７の先端部１７ｂ側から基部１７ａ側に向かって末広がり状となっている。
この背壁部１７において、支持部材４と対向する側の面（内面）には、複数（図例では２つ）の補強リブ１９が支持部９側に向かって突出して形成されている。補強リブ１９は、支持部９に当接する第１辺部２０と、固定部１０に当接する第２辺部２１を有している。第１辺部２０は支持部材４の支持部９に当接する当接面を有し、第２辺部２１は、固定部１０に当接する当接面を有している。 The back wall portion 17 is formed in a taper shape from the base portion 17a side toward the tip end portion 17b (or a shape spreading toward the base portion 17a from the tip end portion 17b side), and the tip end portion 17b is formed in a circular shape. Has been. Therefore, the side wall portion 18 is also widened toward the base portion 17a side from the distal end portion 17b side of the back wall portion 17.
In the back wall portion 17, a plurality of (two in the illustrated example) reinforcing ribs 19 are formed on the surface (inner surface) facing the support member 4 so as to protrude toward the support portion 9 side. The reinforcing rib 19 has a first side portion 20 that contacts the support portion 9 and a second side portion 21 that contacts the fixed portion 10. The first side portion 20 has a contact surface that contacts the support portion 9 of the support member 4, and the second side portion 21 has a contact surface that contacts the fixed portion 10.

図１、図２において、背壁部１７の基部１７ａには、凹部２２が形成されており、この凹部２２にドライバー等の尖端状の工具を差し込むことができるようになっている。
外カバー部材１５には、支持部材４の支持部９に嵌合する第１嵌合部２４と、固定部１０に嵌合する第２嵌合部２５が形成されている。
第１嵌合部２４は、外カバー部材１５の側壁部１８に形成された溝部２６を有し、この溝部２６は、側壁部１８の全周にわたって連続状に形成されている。この溝部２６は、側壁部１８の周方向に沿ってその内面から突出形成された対の突起部２７，２８の間に形成されている。前記側壁部１８は上述のように末広がりとなっているので、第１嵌合部２４の溝部２６は、図２に示すように、取付面Ａに向かってその間隔が末広がり状になっている。 In FIG. 1 and FIG. 2, a concave portion 22 is formed in the base portion 17 a of the back wall portion 17, and a pointed tool such as a screwdriver can be inserted into the concave portion 22.
The outer cover member 15 is formed with a first fitting portion 24 that fits into the support portion 9 of the support member 4 and a second fitting portion 25 that fits into the fixed portion 10.
The first fitting portion 24 has a groove portion 26 formed in the side wall portion 18 of the outer cover member 15, and the groove portion 26 is formed continuously over the entire circumference of the side wall portion 18. The groove 26 is formed between a pair of protrusions 27 and 28 that protrude from the inner surface along the circumferential direction of the side wall 18. Since the side wall 18 is divergent as described above, the groove 26 of the first fitting part 24 is divergent toward the mounting surface A as shown in FIG.

対の突起部の一方（２７）は、側壁部１８の突端側に形成されており（以下、この突起部を第１突起部２７という）、他方の突起部（以下、第２突起部２８という）は、第１突起部２７から離間されて背壁部１７寄りに設けられ、この第１突起部２７と平行に形成されている。
第１突起部２７の突端部には、この第１突起部２７よりもやや小さな突条部３０が形成されており、この突条部３０が内カバー部材１６を係止する係止部（以下、突条部と係止部に共通符号３０を用いる）となっている。 One of the pair of protrusions (27) is formed on the protruding end side of the side wall 18 (hereinafter, this protrusion is referred to as the first protrusion 27), and the other protrusion (hereinafter referred to as the second protrusion 28). ) Is provided away from the first protrusion 27 and close to the back wall 17, and is formed in parallel with the first protrusion 27.
A protruding portion 30 that is slightly smaller than the first protruding portion 27 is formed at the protruding end portion of the first protruding portion 27, and the protruding portion 30 locks the inner cover member 16 (hereinafter referred to as a locking portion). The common reference numeral 30 is used for the protrusion and the locking portion.

前記溝部２６の第２突起部２８側の側壁面は、前記補強リブ１９の第１辺部２０の当接面と面一に形成されている。これによって、外カバー部材１５を支持部材４に取り付けるときに、補強リブ１９の第１辺部２０の当接面を支持部９に当接させてスライドさせるだけで、第１嵌合部２４を支持部９に簡単に案内できるようになっている。しかも、第１嵌合部２４の溝部２６が上述のように取付面Ａに向かって末広がり状となっており、そして前記支持部９が先細り状に構成されていることから、支持部９の中途部からでも第１嵌合部２４に嵌合できるようになっている。 The side wall surface of the groove 26 on the second protrusion 28 side is formed flush with the contact surface of the first side 20 of the reinforcing rib 19. As a result, when the outer cover member 15 is attached to the support member 4, the first fitting portion 24 can be simply moved by bringing the contact surface of the first side portion 20 of the reinforcing rib 19 into contact with the support portion 9 and sliding. The support part 9 can be easily guided. Moreover, since the groove portion 26 of the first fitting portion 24 is diverging toward the mounting surface A as described above, and the support portion 9 is configured to be tapered, the support portion 9 is arranged in the middle. The first fitting part 24 can be fitted even from the part.

前記溝部２６の底面には、支持部材４の凹部１２に嵌合する突起３１が形成されている。前記突起３１は対となっていて互いに対向するように設けられており、外カバー部材１５の支持部材４への取付けの際、第１嵌合部２４が支持部９に嵌合したときに前記突起３１が凹部１２に嵌合して外カバー部材１５の位置決めがなされる。
前記突起３１は、円形状に形成されており、突起３１が凹部１２に嵌合するときに抵抗が極力かからない形状になっている。突起３１は凹部１２よりもやや大きくされており、突起３１は、凹部１２に嵌合したときにこの凹部１２の縁部に当接し、これによって支持部材４に取り付けられた外カバー部材１５がガタつかないようになっている。 On the bottom surface of the groove portion 26, a protrusion 31 that fits into the recess 12 of the support member 4 is formed. The protrusions 31 are paired and provided so as to face each other. When the outer cover member 15 is attached to the support member 4, the first fitting portion 24 is fitted to the support portion 9. The protrusion 31 fits into the recess 12 and the outer cover member 15 is positioned.
The protrusion 31 is formed in a circular shape, and has such a shape that resistance is not exerted as much as possible when the protrusion 31 is fitted into the recess 12. The protrusion 31 is slightly larger than the recess 12, and the protrusion 31 abuts against the edge of the recess 12 when fitted into the recess 12, thereby causing the outer cover member 15 attached to the support member 4 to be loose. It is designed not to connect.

このように、前記突起３１と凹部１２は、外カバー部材１５と支持部材４の間に設けられていて、外カバー部材１５を支持部材４に取り付けたときに外カバー部材１５の位置決めをする位置決め手段３３を構成している。
前記第２嵌合部２５は、外カバー部材１５の基部の内側に設けられている。すなわち、外カバー部材１５の補強リブ１９の第２辺部２１と外カバー部材１５の基端１５ａとの間に固定部１０を収納する空間が形成されており、この空間が固定部１０の嵌合部（第２嵌合部２５）となっている。 As described above, the protrusion 31 and the recess 12 are provided between the outer cover member 15 and the support member 4, and positioning the outer cover member 15 when the outer cover member 15 is attached to the support member 4. Means 33 are configured.
The second fitting portion 25 is provided inside the base portion of the outer cover member 15. That is, a space for accommodating the fixing portion 10 is formed between the second side portion 21 of the reinforcing rib 19 of the outer cover member 15 and the base end 15 a of the outer cover member 15, and this space is fitted into the fixing portion 10. It becomes a joint part (2nd fitting part 25).

外カバー部材１５を支持部材４に取り付けると、支持部９が第１嵌合部２４に嵌り、第２嵌合部２５が固定部１０に嵌り、これによって外カバー部材１５は、支持部９のねじ部材３、固定部１０の固定手段１３のみならず、支持部９、固定部１０のほぼ全体を覆うことができ、手摺り１は支持部材４が露出せずに非常に見栄えのよいものになる。
前記内カバー部材１６は、支持部材４の支持部９の当接面９ｃにおいて、手摺りバー２が当接している部分以外の露出面を目隠しするためのものである。 When the outer cover member 15 is attached to the support member 4, the support portion 9 is fitted into the first fitting portion 24, and the second fitting portion 25 is fitted into the fixing portion 10, whereby the outer cover member 15 is attached to the support portion 9. Not only the fixing means 13 of the screw member 3 and the fixing portion 10 but also the support portion 9 and the fixing portion 10 can be covered almost entirely, and the handrail 1 has a very good appearance without the support member 4 being exposed. Become.
The inner cover member 16 is for concealing an exposed surface other than a portion where the handrail bar 2 is in contact with the contact surface 9 c of the support portion 9 of the support member 4.

内カバー部材１６は、合成樹脂製で板状に形成されており、円弧状の第１辺部３５と、この第１辺部３５の反対側に設けられていて直線状に形成された第２辺部３６と、第２辺部３６から第１辺部３５に向かって内カバー部材１６が先細り状となるようにテーパ状に傾斜した第３辺部３７、第４辺部３８が形成されている。
前記第１辺部３５は、内カバー部材１６が支持部材４に取り付けられたときに、外カバー部材１５の先端部とともに手摺りバー２の端部の周縁を覆うようになっている。 The inner cover member 16 is made of a synthetic resin and is formed in a plate shape. The first side portion 35 has an arc shape, and a second side portion that is provided on the opposite side of the first side portion 35 and has a linear shape. A side part 36, a third side part 37 and a fourth side part 38 that are inclined in a tapered shape so that the inner cover member 16 is tapered from the second side part 36 toward the first side part 35 are formed. Yes.
The first side portion 35 covers the periphery of the end portion of the handrail bar 2 together with the distal end portion of the outer cover member 15 when the inner cover member 16 is attached to the support member 4.

第２辺部３６は、手摺り１を取付面Ａに取り付けたときに、この取付面Ａに当接するようになっている。
第３辺部３７、第４辺部３８には、外カバー部材１５の前記係止部３０に係合する係合突起部３９が形成されている。この係合突起部３９は、第３辺部３７、第４辺部３８の全長にわたって連続状に形成されている。 The second side 36 comes into contact with the attachment surface A when the handrail 1 is attached to the attachment surface A.
On the third side portion 37 and the fourth side portion 38, an engaging protrusion 39 that engages with the locking portion 30 of the outer cover member 15 is formed. The engaging protrusion 39 is formed continuously over the entire length of the third side 37 and the fourth side 38.

手摺り１を取付面Ａに取り付けるには、まず、予め所定長さに切断された手摺りバー２の螺合部６に支持部９をねじ部材３を介して連結することによって、手摺りバー２の両端部に支持部材４を取り付ける。その後に固定部１０を固定手段１３によって取付面Ａに固定する。
次に、内カバー部材１６を斜めに傾斜させた状態（図１の２点鎖線で示す状態）で取付面Ａと手摺りバー２の間に入れ、それから支持部９の手摺りバー２側の面に当接（図１の実線で示す状態）させて保持しておく。 In order to attach the handrail 1 to the attachment surface A, first, a handrail bar is formed by connecting a support portion 9 via a screw member 3 to a screwing portion 6 of a handrail bar 2 that has been cut to a predetermined length in advance. The support member 4 is attached to both ends of 2. Thereafter, the fixing portion 10 is fixed to the mounting surface A by the fixing means 13.
Next, in a state where the inner cover member 16 is inclined obliquely (state shown by a two-dot chain line in FIG. 1), the inner cover member 16 is inserted between the attachment surface A and the handrail bar 2, and then the support portion 9 on the handrail bar 2 side It is held in contact with the surface (state shown by the solid line in FIG. 1).

そして、外カバー部材１５を支持部材４に取り付ける。このとき、外カバー部材１５の補強リブ１９の第１辺部２０の当接面を支持部９の固定部１０側の面に当接させ、そのまま外カバー部材１５をスライドさせて、支持部９に第１嵌合部２４を嵌合させる。これとほぼ同時に、支持部９の当接面９ｃ（露出面）に当接された内カバー部材１６が外カバー部材１５と係合する。この係合は、内カバー部材１６の係合突起部３９が、外カバー部材１５の係止部３０と支持部材４の支持部９との間に入り込むことによりなされる。 Then, the outer cover member 15 is attached to the support member 4. At this time, the abutment surface of the first side portion 20 of the reinforcing rib 19 of the outer cover member 15 is brought into contact with the surface of the support portion 9 on the fixed portion 10 side, and the outer cover member 15 is slid as it is to thereby support the support portion 9. The 1st fitting part 24 is fitted to. At substantially the same time, the inner cover member 16 in contact with the contact surface 9 c (exposed surface) of the support portion 9 engages with the outer cover member 15. This engagement is achieved by the engagement protrusion 39 of the inner cover member 16 entering between the locking portion 30 of the outer cover member 15 and the support portion 9 of the support member 4.

これによって、内カバー部材１６は、外カバー部材１５の第１嵌合部２４（係止部３０）に係止され、支持部９の当接面９ｃ側の露出面を目隠しする位置に位置決めされることになる。したがって、内カバー部材１６が外カバー部材１５から離れることなく、この内カバー部材１６と外カバー部材１５とで支持部材４のほぼ全体が覆われることになる。
そして、固定部１０に第２嵌合部２５を嵌合させる。第２嵌合部２５が固定部１０に嵌合する際に位置決め手段３３の突起３１が凹部１２に嵌合し、外カバー部材１５が支持部９に固定（位置決め）され、以上によって手摺り１の取付面Ａへの取り付けが完了する。 As a result, the inner cover member 16 is locked to the first fitting portion 24 (locking portion 30) of the outer cover member 15, and is positioned at a position where the exposed surface of the support portion 9 on the contact surface 9c side is blinded. Will be. Accordingly, the inner cover member 16 and the outer cover member 15 cover almost the entire support member 4 without the inner cover member 16 being separated from the outer cover member 15.
Then, the second fitting portion 25 is fitted to the fixed portion 10. When the second fitting portion 25 is fitted to the fixed portion 10, the protrusion 31 of the positioning means 33 is fitted to the concave portion 12, and the outer cover member 15 is fixed (positioned) to the support portion 9. Is attached to the mounting surface A.

手摺りバー２を交換するには、外カバー部材１５を引っ張って取り外し、支持部９と手摺りバー２とを連結しているねじ部材３を取り外す。外カバー部材１５の取り外しの際には、外カバー部材１５の背壁部１７に形成された凹部２２にドライバー等の工具を差し込んで取り外してもよい。
支持部材４に外カバー部材１５が取付けられると、補強リブ１９の第１辺部２０の当接面は支持部９に当接し、第２辺部２１の当接面は固定部１０に当接した状態になる。このように、外カバー部材１５を支持部材４に取り付けた状態では、補強リブ１９が支持部材４に当接して外部からの衝撃・荷重等によって外カバー部材１５が変形しないようになっている。 In order to replace the handrail bar 2, the outer cover member 15 is pulled and removed, and the screw member 3 connecting the support portion 9 and the handrail bar 2 is removed. When removing the outer cover member 15, a tool such as a screwdriver may be inserted into the recess 22 formed in the back wall portion 17 of the outer cover member 15 and removed.
When the outer cover member 15 is attached to the support member 4, the contact surface of the first side portion 20 of the reinforcing rib 19 contacts the support portion 9, and the contact surface of the second side portion 21 contacts the fixed portion 10. It will be in the state. As described above, in a state where the outer cover member 15 is attached to the support member 4, the reinforcing rib 19 abuts against the support member 4 so that the outer cover member 15 is not deformed by an external impact / load.

図５の第２実施形態では、補強リブ１９の形状が第１実施形態の場合と異なる。
すなわち、図５に示すように、補強リブ１９の第１辺部２０の近傍には、支持部９と手摺りバー２を連結しているねじ部材３の抜け止めをする抜け止め部４０が支持部材４の支持部９と対向するように形成されている。この抜け止め部４０はねじ部材３の頭部に近接しており、ねじ部材３が外れる方向に回転してもこのねじ部材３の頭部が抜け止め部４０に当接して後退できない（抜けはずれない）ようになっている。その他の点は、第１実施形態と同様の構成であり、同様の作用効果を奏する。 In 2nd Embodiment of FIG. 5, the shape of the reinforcement rib 19 differs from the case of 1st Embodiment.
That is, as shown in FIG. 5, in the vicinity of the first side portion 20 of the reinforcing rib 19, a retaining portion 40 for retaining the screw member 3 connecting the supporting portion 9 and the handrail bar 2 is supported. It is formed so as to face the support portion 9 of the member 4. The retaining portion 40 is close to the head of the screw member 3, and even if the screw member 3 rotates in the direction in which it is removed, the head of the screw member 3 abuts on the retaining portion 40 and cannot be retracted (disengagement is lost). Not). The other points are the same as those in the first embodiment, and have the same effects.

なお、本発明は上記の実施の形態に限らず、以下のような変更が可能である。
例えば、位置決め手段３３は、支持部９の凹部１２と外カバー部材１５の突起３１で構成していたが、支持部９に突起、外カバー部材１５に凹部を設けて構成してもよい。また、手摺りバー２は円筒状のものに限らず、多角筒等その他の種々の形状のものを使用できる。螺合部６は、手摺りバー２内面の３箇所以上の複数箇所に形成してもよい。固定手段１３はねじ部材に限らず、アンカーボルト等その他の種々の手段を用いてもよい。 The present invention is not limited to the above-described embodiment, and the following modifications are possible.
For example, the positioning means 33 is configured by the concave portion 12 of the support portion 9 and the projection 31 of the outer cover member 15, but may be configured by providing a projection on the support portion 9 and a concave portion on the outer cover member 15. In addition, the handrail bar 2 is not limited to a cylindrical shape, and various other shapes such as a polygonal tube can be used.
