隣接する手すり部材を接続する手すり用接続具として、隣接する手すり部材の対向端部を嵌入固定し得る２つの手すり接続部からなり、その手すり接続部同士を嵌合した状態で摺動可能にする連結具が提案されている（例えば、特許文献１参照）。   As a handrail connection tool for connecting adjacent handrail members, it is composed of two handrail connection portions that can be fitted and fixed at opposite ends of adjacent handrail members, and is slidable with the handrail connection portions fitted together. A connector has been proposed (see, for example, Patent Document 1).

特開平１１―６２６７号公報Japanese Patent Laid-Open No. 11-6267

この手すり用接続具の接続部同士は連結具の両端に備えられた押え部材によって連結されているものであり、この押え部材は樹脂材等を主体として形成され、摺動することを可能としている。   The connection portions of the handrail connecting device are connected by pressing members provided at both ends of the connecting device, and the pressing member is formed mainly of a resin material and can slide. .

しかしながら、このような押え部材により接続部同士を摺動可能で適度な摩擦力を有しながら固定するには、押え部材を接続部の内周面へ圧入して調整する必要があった。そのため、第一に、接続部の形状（製造時に発生する形状の誤差などを含む）ごとに押え部材の圧入を調整すること、第二に、その圧入を連結具両端に備える押え部材に対して行うこと、が必要であり摩擦力の調整が難しいのみならず、組み立て作業に手間が掛かるという欠点があった。   However, in order to fix the slidable connecting portions with such a pressing member and having an appropriate frictional force, it is necessary to press the pressing member into the inner peripheral surface of the connecting portion for adjustment. Therefore, first, adjust the press-fitting of the presser member for each shape of the connecting portion (including the error of the shape generated at the time of manufacture), and secondly, to the presser member provided with the press-fit at both ends of the connector This is not only difficult to adjust the frictional force, but also has the disadvantage that it takes time to assemble.

これらの欠点を解消するべく、本発明では、摺動可能な摩擦力を発生するための部材と、接続部から延設された突出部による連結部材と、をそれぞれ独立に備えることで、組立作業と、摺動可能な摩擦力の調整と、を容易に実施することができる手すり用接続具を提供する。   In order to eliminate these drawbacks, in the present invention, an assembly operation is provided by independently including a member for generating a slidable frictional force and a connecting member by a protruding portion extending from the connecting portion.

本発明の実施形態について図１ないし図４に基づいて詳細に説明する。ここに例示する手すり接続具Aは、図１に示すように、隣接する手すり部材の対向端部を嵌入固定し得る第一手すり接続部１と第二手すり接続部２からなり、その第一手すり接続部１が略半球面状の凸部材１aと、第二手すり接続部２が前記凸部材１aを嵌合する凹部材２aと、前記凸部材１aから延設した突出部１ｂと、前記凹部材２aが前記突出部１ｂを嵌入し得る前記溝２ｂと、を有し、突出部１ｂを溝２ｂに嵌入保持して連結した状態であり、嵌合空間に弾性部材を挟み込むことで摺動自在にしたものである。   An embodiment of the present invention will be described in detail with reference to FIGS. As shown in FIG. 1, the handrail connector A exemplified here includes a first handrail connection portion 1 and a second handrail connection portion 2 that can fit and fix opposite ends of adjacent handrail members, and the first handrail. A convex member 1a having a substantially hemispherical connection portion 1, a concave member 2a in which the second handrail connecting portion 2 fits the convex member 1a, a protruding portion 1b extending from the convex member 1a, and the concave member 2a has the groove 2b into which the protruding portion 1b can be inserted, and is in a state where the protruding portion 1b is fitted and held in the groove 2b and is slidable by inserting an elastic member in the fitting space. It is what.

第一手すり接続部１は、略半球状の凸部材１ａの反対側の端部に円筒状筒体１ｃが設けられており、隣接する手すり部材９の対向端部を挿入し、固定ねじ６で固定する。   The first handrail connecting portion 1 is provided with a cylindrical cylindrical body 1c at the opposite end of the substantially hemispherical convex member 1a, and the opposite end portion of the adjacent handrail member 9 is inserted, and the fixing screw 6 is used. Fix it.

このとき、円筒状筒体１ｃは、欠損円筒状筒体１ｃ１と手すり固定部１ｃ２とに分割して、固定ねじ７を欠損円筒状筒体１ｃ１の雌ねじ部１ｅに螺着することで両者を固定して一体とする。 At this time, the cylindrical tubular body 1c is divided into a defect cylindrical tubular body 1c 1 and handrail fixed portion 1c 2, by screwing the fixing screw 7 into the internal thread portion 1e of the defect cylindrical tubular body 1c 1 Both are fixed and integrated.

そして、この円筒状筒体１ｃの軸方向の凸部材１aには、固定具支持部１ｂ１である雌ねじ部を有する円筒状筒体からなる突出部１ｂを延設されている。 And the protrusion part 1b which consists of a cylindrical cylinder which has the internal thread part which is the fixing tool support part 1b 1 is extended by the convex member 1a of the axial direction of this cylindrical cylinder 1c.

上述した構成から、凸部材１ａから延設された突出部１ｂが一体として形成されていることから、凹部材２ａの溝２ｂへの嵌入保持する状態において、その突出部１ｂの高さに応じて、凸部材１ａと凹部材２ａとの間に一定の嵌合空間を設けることができる（例えば、図２(ｂ)、図２(ｃ)参照）。つまり、突出部１ｂが一定の嵌合空間を有するように、その突出高さを設けているのであり、突出部１ｂに固定具３であるねじを強固に締め込んだ場合であっても、一定の嵌合空間が確保できる。従来の接続具では使用者、施工者による押圧部材の圧入する加減で当該空間の大きさが決まっていたため、摺動が円滑になされない場合があったが、本実施形態では、このような不都合がない。   From the configuration described above, since the protruding portion 1b extending from the convex member 1a is integrally formed, in a state where the concave member 2a is fitted and held in the groove 2b, depending on the height of the protruding portion 1b. A fixed fitting space can be provided between the convex member 1a and the concave member 2a (see, for example, FIGS. 2B and 2C). That is, the protrusion height is provided so that the protrusion 1b has a constant fitting space, and even if the screw that is the fixture 3 is firmly tightened to the protrusion 1b, the protrusion 1b is constant. Can be secured. In the conventional connector, since the size of the space is determined by the press-fitting of the pressing member by the user or the installer, the sliding may not be performed smoothly. There is no.

また、突出部１ｂは凸部材１ａと一体的に形成されていることから、凸部材１ａ側の内周面を押える押え部材を必要せず、また、固定具３、押え部材４や固定具支持部１ｂ１は固定ねじ、座金や雌ねじ部などの汎用性の高い部品を用いることができるため、安価で容易に組み立てることができる。 Further, since the protruding portion 1b is formed integrally with the convex member 1a, there is no need for a pressing member for pressing the inner peripheral surface on the convex member 1a side, and the fixing tool 3, the pressing member 4 and the fixing tool support are not required. Since the part 1b 1 can use highly versatile parts such as a fixing screw, a washer and a female screw part, it can be easily assembled at low cost.

また、あらかじめ壁に取り付けた手すり支持部との固定する方向に合わせて第一手すり接続部１を軸方向に摺動回転させ、第一手すり接続部１の固定ねじ７を外して手すり部材９と手すり固定部１ｃ２とが欠損円筒状筒体１ｃ１を分離させることで、手すり支持部と手すり部材９の取り付けや取り外しが簡単に施行でき、かつ、手すり固定部１ｃ２と手すり部材９の固定ねじ６を繰り返し取り付けることによる手すり部材９の劣化を防ぐことができる。 In addition, the first handrail connection portion 1 is slid and rotated in the axial direction in accordance with the direction of fixing with the handrail support portion attached to the wall in advance, and the fixing screw 7 of the first handrail connection portion 1 is removed to remove the handrail member 9. by a handrail fixed portion 1c 2 is to isolate the missing cylindrical tubular body 1c 1, installation and removal of the handrail support and handrail member 9 can be easily enforced and railing fixing of the fixed portion 1c 2 and the handrail member 9 Deterioration of the handrail member 9 due to repeated mounting of the screw 6 can be prevented.

第二手すり接続部２には、凸部材１ａを嵌合する凹部材２ａの反対側の端部に円筒状筒体２ｃが設けられており、この円筒状筒体２ｃに隣接する手すり部材１０の対向端部を嵌入し、固定ねじ８で固定する。   The second handrail connecting portion 2 is provided with a cylindrical cylindrical body 2c at the opposite end of the concave member 2a into which the convex member 1a is fitted, and the handrail member 10 adjacent to the cylindrical cylindrical body 2c is provided. The opposite end is inserted and fixed with a fixing screw 8.

そして、凹部材２ａには、円筒状筒体２ｃの軸方向と交差するように凹部材２ａ上に溝２ｂと、弾性部材５を凹部材２aの外周面に沿って固定するための小孔２ｄと、が形成されている。   The recess 2a has a groove 2b on the recess 2a so as to intersect the axial direction of the cylindrical tube 2c, and a small hole 2d for fixing the elastic member 5 along the outer peripheral surface of the recess 2a. And are formed.

上述した構成から、凸部材１ａを嵌合するように形成した凹部材２ａと、その凹部材２ａの溝２ｂへ突出部１ｂを嵌入保持した状態で、溝２ｂに沿って摺動させることで、第一手すり接続部１と第二手すり接続部２とを任意の角度に変更することが可能である。例えば、図３では鈍角に固定し、図４では直角に固定している状態を示す。   From the above-described configuration, by sliding along the groove 2b with the recessed member 2a formed so as to fit the protruding member 1a and the protruding portion 1b fitted and held in the groove 2b of the recessed member 2a, It is possible to change the 1st handrail connection part 1 and the 2nd handrail connection part 2 to arbitrary angles. For example, FIG. 3 shows a state where the obtuse angle is fixed, and FIG. 4 shows a state where the obtuse angle is fixed at a right angle.

また、凹部材２ａの小孔２ｄで嵌合空間に挟み込む弾性部材５を固定して、摺動時に凹部材２ａの外周面に弾性部材５が追従することで、嵌合空間から露出しないようにすることができる。つまり、図３、図４に示すように、摺動にあたり、凸部材１ａは露出する部分が移動するためである。   Further, the elastic member 5 sandwiched in the fitting space by the small hole 2d of the concave member 2a is fixed, and the elastic member 5 follows the outer peripheral surface of the concave member 2a during sliding so that it is not exposed from the fitting space. can do. That is, as shown in FIGS. 3 and 4, the exposed portion of the convex member 1 a moves during sliding.

弾性部材５は、凸部材１ａ及び凹部材２ａの外周面に沿う殻状体であり、この弾性部材５には凹部材２ａと接する面に突起5ｂと、突出部１ｂを溝２ｂへの嵌入することを妨げないような大きさの長孔５ａと、が設けられている。この突起５ｂを凹部材２ａの小孔２ｄへと嵌入して、弾性部材５と凹部材２ａとを摺動させずに、追従するように固定することができる。   The elastic member 5 is a shell-like body along the outer peripheral surfaces of the convex member 1a and the concave member 2a. The elastic member 5 has a projection 5b and a projection 1b fitted into the groove 2b on the surface in contact with the concave member 2a. A long hole 5a having a size that does not prevent this is provided. The protrusion 5b can be fitted into the small hole 2d of the concave member 2a, and can be fixed to follow the elastic member 5 and the concave member 2a without sliding.

このとき、弾性部材５の殻状体は、嵌合空間に挟み込まれている状態において、凸部材１ａまたは凹部材２ａの外周面の一部と接し、それ以外の部分とは空隙を有する形状であることが好ましい。例えば、図２(b)の拡大断面図Bに示すように、略半球面状でその周縁部５ｃのみが凸部材１ａの外周面に接しているものや、図２(c)の拡大断面図Cに示すように、断面形状が波状で、波の頂点が凸部材１ａ又は凹部材２ａの外周面上に接しているものであってもよい。   At this time, the shell-like body of the elastic member 5 is in a state of being in contact with a part of the outer peripheral surface of the convex member 1a or the concave member 2a while being sandwiched in the fitting space, and having a gap with the other parts. Preferably there is. For example, as shown in an enlarged sectional view B of FIG. 2 (b), a substantially hemispherical shape in which only the peripheral edge 5c is in contact with the outer peripheral surface of the convex member 1a, or an enlarged sectional view of FIG. 2 (c). As shown in C, the cross-sectional shape may be wavy and the top of the wave may be in contact with the outer peripheral surface of the convex member 1a or the concave member 2a.

上述した構成から、突出部１ｂを溝２ｂへ嵌入保持することを妨げないで、設けられた一定の嵌合空間に、一定の大きさを有する殻状体の弾性部材５を挟み込むことができる。   From the above-described configuration, the shell-like elastic member 5 having a certain size can be sandwiched in the certain fitting space provided without preventing the protrusion 1b from being fitted and held in the groove 2b.

また、この弾性部材５の反発力に応じて摩擦力が凸部材１ａと凹部材２ａに生じる。この弾性部材５の殻状体と凸部材１ａと凹部材２ａとの接する面の形状によって、生じる摩擦力を調整することが可能である。例えば、殻状体の周縁部５ｃのみ接した状態で摺動可能な摩擦力を生じるように形成した弾性部材５を用いることで、容易に組み立てることが可能である。   Further, a frictional force is generated in the convex member 1a and the concave member 2a according to the repulsive force of the elastic member 5. The generated frictional force can be adjusted by the shape of the surface of the elastic member 5 in contact with the shell, the convex member 1a and the concave member 2a. For example, it is possible to easily assemble by using the elastic member 5 formed so as to generate a sliding frictional force in a state where only the peripheral edge portion 5c of the shell-like body is in contact.

したがって、第１手すり接続部１から延設された連結部材である突出部１ｂと、摺動可能な摩擦力を発生するための部材である弾性部材５をそれぞれ独立に備えることで、従来の連結具及び押え部材の圧入による摺動可能な摩擦力の調整を必要とせず、組立作業と、摺動可能な摩擦力の調整と、を容易に実施することができる手すり用接続具を提供することが可能である。   Therefore, the conventional connection is provided by independently including the protruding portion 1b that is a connecting member extending from the first handrail connecting portion 1 and the elastic member 5 that is a member for generating a sliding frictional force. Provided is a handrail connection tool that can easily perform assembly work and adjustment of slidable friction force without requiring adjustment of slidable friction force by press-fitting of a tool and a presser member. Is possible.

上記の実施形態では本発明の好ましい実施形態を例示したが、本発明は上記の実施形態に限定されるものではなく、特許請求の範囲に記載した範囲内で改善や変更が可能である。例えば、第一手すり接続部１に設けた手すり固定部１ｃ２を第二手すり接続部２に設けること、凹部材２ａに突出部１ｂを延設し凸部材１ａに溝２ｂ備えること、も可能であり、また弾性部材５を内部に空隙を有するようなスポンジ状のものとすることも可能である。 In the above embodiment, the preferred embodiment of the present invention has been exemplified. However, the present invention is not limited to the above embodiment, and can be improved or changed within the scope described in the claims. For example, it is possible to provide the handrail fixing portion 1c 2 provided in the first handrail connecting portion 1 in the second handrail connecting portion 2, or to provide the protruding portion 1b in the recessed member 2a and the groove 2b in the protruding member 1a. In addition, the elastic member 5 may be a sponge-like member having a gap inside.
