Description

本考案は、二本の木製手摺棒の端部同士を連結する手摺棒の連結構造に関する。 The present invention relates to a connecting structure of handrail bars for connecting ends of two wooden handrail bars.

木製手摺棒を連結する構造としては、二本の手摺棒の端面間に挟まれる中挟板の周囲に、手摺棒の外周に被さるフランジを設け、ブラケットの受部上で手摺棒同士を連結する構造が知られている（例えば、特許文献１）。 As a structure for connecting wooden handrail bars, a flange covering the outer periphery of the handrail bar is provided around the intermediate sandwiched plate sandwiched between the end surfaces of the two handrail bars, and the handrail bars are connected to each other on the bracket receiving part. The structure is known (for example, Patent Document 1).

特許第４２４３８０４号公報Japanese Patent No. 4243804

上記特許文献１に記載の連結構造では、手摺棒同士の連結強度を高めるには、各手摺棒の端部を受部に螺着する木螺子の数を増やせばよいが、木螺子の数を増やすと、受部を大きくしなければならず、受部の設計自由度が制限される。また、木螺子の本数が多くなると、螺子止め作業の手間も大きくなる。 In the connection structure described in Patent Document 1, in order to increase the connection strength between the handrail bars, the number of wood screws for screwing the end portions of the handrail bars to the receiving portion may be increased. If it increases, a receiving part must be enlarged and the design freedom of a receiving part will be restrict | limited. Further, when the number of wood screws increases, the labor for screwing work increases.

本考案は、かかる現状に鑑みてなされたものであり、木螺子の本数を増やさずに手摺棒を強固に連結できる手摺棒の連結構造の提供を目的とする。 The present invention has been made in view of the present situation, and an object of the present invention is to provide a handrail bar connection structure that can firmly connect handrail bars without increasing the number of wood screws.

本考案は、二本の木製手摺棒の端部同士を連結する手摺棒の連結構造であって、両手摺棒の連結部分を跨いで両手摺棒の端部外周面に結合される受部が設けられた、手摺棒を壁面に固定するためのブラケットを備え、両手摺棒は、木螺子によって前記受部に螺着されることにより、相互に分離不能に連結されており、両手摺棒の端面にダボ穴が対向状に形成され、該ダボ穴に跨るようにダボが挿入されており、両手摺棒を受部に螺着する前記木螺子は、前記ダボと夫々螺合していることを特徴とする手摺棒の連結構造である。 The present invention is a connecting structure of handrail bars that connect the ends of two wooden handrail bars, and a receiving portion that is coupled to the outer peripheral surface of the ends of both handrail bars across the connecting portion of both handrail bars. Provided with a bracket for fixing the handrail bar to the wall surface, and the both handrail bars are connected to the receiving portion by a wood screw so as to be inseparable from each other. A dowel hole is formed in the end face in an opposing manner, a dowel is inserted so as to straddle the dowel hole, and the wood screw for screwing both handrail bars to the receiving part is screwed with the dowel respectively. It is the connection structure of the handrail stick characterized by these.

かかる構成にあっては、二本の手摺棒がダボと受部とを介して夫々連結されるだけでなく、手摺棒を受部に螺着する木螺子がダボと螺合することで、両手摺棒と受部とダボとが木螺子によって一体的に螺着されることとなり、これにより、両手摺棒を強固に連結することが可能となる。したがって、かかる構成によれば、木螺子の本数を増やすことなく、従来構成に比して二本の手摺棒を強固に連結可能となる。 In such a configuration, not only the two handrail bars are connected to each other via the dowel and the receiving portion, but also the wood screw that screws the handrail rod to the receiving portion is screwed with the dowel so that both hands The slide bar, the receiving portion, and the dowel are integrally screwed together by the wood screw, thereby making it possible to firmly connect the handrail bars. Therefore, according to such a configuration, two handrail bars can be firmly connected as compared with the conventional configuration without increasing the number of wood screws.

本考案にあって、連結する手摺棒の端部のうち、一方の端部外周縁に周方向に沿って内側に凹む段部が形成されており、両手摺棒の継ぎ目に、前記段部を底部とする周方向の目地溝が露出している構成が提案される。かかる構成にあっては、両手摺棒の継ぎ目が露出していても、継ぎ目に形成された目地溝によって、両手摺棒の木目の相違が目立たなくなる。従来の手摺棒の連結構造では、手摺棒の継ぎ目における木目の不一致を隠すために、手摺棒間にフランジ付きの中挾板を介装して継ぎ目を覆うようにしているが、本構成によれば、手摺棒の継ぎ目を覆わなくても、手摺棒を違和感なく連結させることができるから、従来構成に比して部品点数の削減が可能となる。 In the present invention, among the ends of the handrail rods to be connected, a stepped portion that is recessed inward along the circumferential direction is formed on the outer peripheral edge of one end portion. A configuration is proposed in which the joint groove in the circumferential direction as the bottom is exposed. In such a configuration, even if the joint of the two handrail bars is exposed, the difference in the grain of the two handrail bars becomes inconspicuous due to the joint groove formed in the joint. In the conventional handrail bar connection structure, in order to conceal the discrepancy between the joints of the handrail bars, a flanged intermediate plate is interposed between the handrail bars to cover the seam. In this case, since the handrail bars can be connected without a sense of incongruity without covering the joints of the handrail bars, the number of parts can be reduced as compared with the conventional configuration.

また、上記目地溝を備える構成にあっては、連結する手摺棒の端部のうち、他方の端部外周縁の、前記段部と対向する位置に、先端側に突出する周方向に沿った突出部が形成されており、該突出部により、両手摺棒の端面同士の接合部が覆われている構成が提案される。かかる構成にあっては、端面同士の接合部が突出部によって覆われるため、両手摺棒を連結する際に、端面間に多少の隙間が生じていても、当該隙間が外部に露出せず、意匠性を損なうことがない。このため、かかる構成によれば、手摺棒の寸法精度を比較的緩めにすることができ、また、施工上の許容誤差も比較的大きくできる。 Moreover, in the structure provided with the said joint groove | channel, it was along the circumferential direction which protrudes in the front end side in the position which opposes the said step part of the other edge part outer periphery among the edge parts of the handrail rod to connect. Protrusions are formed, and a structure is proposed in which the joints between the end surfaces of the two handrail bars are covered by the protrusions. In such a configuration, since the joint portion between the end surfaces is covered by the protruding portion, even when a slight gap occurs between the end surfaces when connecting the handrail bars, the gap is not exposed to the outside. There is no loss of design. For this reason, according to this structure, the dimensional accuracy of a handrail bar can be made loose comparatively, and the tolerance on construction can also be made comparatively large.

また、本考案にあっては、両手摺棒の端面の間に、フランジ付きの中挟板が介装され、該中挟板には、前記ダボが貫通する貫通孔が形成されている構成が提案される。かかる構成によれば、中挾板を介して手摺棒を連結する構造にも、本考案を容易に適用できる。 Further, in the present invention, a flanged intermediate sandwich plate is interposed between the end surfaces of the two handrail rods, and a through hole through which the dowel is formed is formed in the intermediate sandwich plate. Proposed. According to such a configuration, the present invention can be easily applied to a structure in which the handrail bar is connected via the intermediate saddle plate.

以上のように、本考案によれば、木螺子の本数を増やさずに手摺棒を強固に連結させることができるから、受部のサイズが制限されず、ブラケットの設計自由度を高めることができる。 As described above, according to the present invention, since the handrail bar can be firmly connected without increasing the number of wood screws, the size of the receiving portion is not limited, and the degree of freedom in designing the bracket can be increased. .

本考案の実施形態を、以下の実施例に従って説明する。 Embodiments of the present invention will be described according to the following examples.

図１は、本実施例の手摺棒の連結構造を示す斜視図である。かかる連結構造では、二本の手摺棒１ａ，１ｂを、ダボ３を介して連結するとともに、該連結部分の外周面にブラケット２の受部２０を宛てがい、両手摺棒１ａ，１ｂの端部を木螺子４によって受部２０に螺着するとともに、各木螺子４を手摺棒１ａ，１ｂの端部に挿入されたダボ３と螺合させてなるものである。 FIG. 1 is a perspective view showing the connection structure of the handrail bar of this embodiment. In such a connection structure, the two handrail bars 1a and 1b are connected via the dowel 3 and the receiving portion 20 of the bracket 2 is directed to the outer peripheral surface of the connection portion, so that the end portions of the two handrail bars 1a and 1b are connected. Are screwed to the receiving portion 20 by the wood screws 4, and each wood screw 4 is screwed to the dowel 3 inserted at the ends of the handrail rods 1a, 1b.

二本の手摺棒１ａ，１ｂは、図１に示すように、直線状の木製棒材である。両手摺棒１ａ，１ｂの断面は、同径の円形状をなしており、その端部は横断状に切断されている。両手摺棒１ａ，１ｂの端面１０ａ，１０ｂには、円形のダボ穴１３，１３が中心に形成されており、連結状態にあって、このダボ穴１３，１３を跨ぐように硬質木材からなるダボ３が挿入される。また、一方の手摺棒１ａの端部外周縁には、図１（ｂ）に示すように、内側に凹む段部１１が全周に亘って形成される。そして、他方の手摺棒１ｂの端部外周縁には、段部１１と対向する位置に、先端方向に突出する突出部１２が全周に亘って形成され、連結状態にあって、突出部１２が段部１１の凹みと嵌合するよう構成される。 As shown in FIG. 1, the two handrail bars 1a and 1b are linear wooden bars. The cross sections of the two handrail rods 1a and 1b have a circular shape with the same diameter, and their ends are cut in a transverse shape. Circular dowel holes 13, 13 are formed in the end surfaces 10 a, 10 b of the two handrail rods 1 a, 1 b at the center, and in the connected state, dowels made of hard wood so as to straddle the dowel holes 13, 13. 3 is inserted. Moreover, as shown in FIG.1 (b), the step part 11 dented inside is formed in the outer periphery of the edge part of one handrail rod 1a over the perimeter. And the protrusion part 12 which protrudes in the front-end | tip direction in the position facing the step part 11 is formed in the outer periphery of the edge part of the other handrail stick 1b over the perimeter, and is in the connection state, and the protrusion part 12 Is configured to fit into the recess of the stepped portion 11.

ブラケット２は、壁面に固定される取付部２１と、手摺棒１ａ，１ｂに下方から当接して手摺棒１ａ，１ｂを保持する受部２０と、取付部２１と受部２０を連繋する腕部２２とを備えてなる金具である。取付部２１は、木螺子によって壁面に螺着されるものであり、木螺子を挿通する螺子孔（図示省略）は、キャップ２３によって覆われている。腕部２２は取付部２１から斜め上方にＬ字状に延出しており、受部２０は、腕部２２の上端に一体的に設けられている。受部２０は、手摺棒１ａ，１ｂの連結方向に長尺な板状をなし、その上面は手摺棒１ａ，１ｂの外周面に被着し得るように湾曲している。また、受部２０には、木螺子４を挿通する一対の螺子孔２４，２４が形成される。 The bracket 2 includes a mounting portion 21 fixed to the wall surface, a receiving portion 20 that contacts the handrail rods 1a and 1b from below and holds the handrail rods 1a and 1b, and an arm portion that connects the mounting portion 21 and the receiving portion 20 together. 22 is a metal fitting. The attachment portion 21 is screwed onto the wall surface with a wood screw, and a screw hole (not shown) through which the wood screw is inserted is covered with a cap 23. The arm portion 22 extends in an L shape obliquely upward from the mounting portion 21, and the receiving portion 20 is integrally provided at the upper end of the arm portion 22. The receiving part 20 has a long plate shape in the connecting direction of the handrail bars 1a and 1b, and its upper surface is curved so as to be attached to the outer peripheral surface of the handrail bars 1a and 1b. The receiving portion 20 is formed with a pair of screw holes 24 and 24 through which the wood screw 4 is inserted.

二本の手摺棒１ａ，１ｂを連結する際は、まず、両手摺棒１ａ，１ｂのダボ穴１３にダボ３を挿入し、両手摺棒１ａ，１ｂが一直線状となるようにして端面１０ａ，１０ｂ同士を当接させる。次に、ブラケット２の受部２０を、連結部分を跨ぐようにして、両手摺棒１ａ，１ｂの端部外周面に下方から宛てがう。そして、かかる状態で、受部２０の螺子孔２４，２４介して手摺棒１ａ，１ｂに木螺子４，４をねじ込み、両手摺棒１ａ，１ｂを受部２０に螺着する。この時、木螺子４の先端は、両手摺棒１ａ，１ｂの中心まで到達させる。 When connecting the two handrail bars 1a, 1b, first, the dowel 3 is inserted into the dowel hole 13 of the two handrail bars 1a, 1b, and the end faces 10a, 10b are brought into contact with each other. Next, the receiving part 20 of the bracket 2 is applied from below to the outer peripheral surfaces of the end parts of the two handrail bars 1a and 1b so as to straddle the connecting part. In this state, the wood screws 4 and 4 are screwed into the handrail rods 1 a and 1 b through the screw holes 24 and 24 of the receiving portion 20, and the both handrail rods 1 a and 1 b are screwed to the receiving portion 20. At this time, the tip of the wood screw 4 reaches the center of the two handrail bars 1a and 1b.

かかる連結構造では、図２〜４に示すように、手摺棒１ａ，１ｂが、受部２０を介して連結されるとともに、ダボ３を介しても相互に連結される。ここで、本実施例では、手摺棒１ａ，１ｂを受部２０に螺着する各木螺子４が、手摺棒１ａ，１ｂの中心まで達してダボ３と螺合しており、これにより、手摺棒１ａ，１ｂと、ダボ３と、ブラケット２の受部２０とが、二本の木螺子４によって分離不能に螺着される。このため、本実施例では、手摺棒１ａ，１ｂに木螺子４，４を一本ずつ螺着するだけでも、二本の手摺棒１ａ，１ｂを強固に連結することができる。 In such a connection structure, as shown in FIGS. 2 to 4, the handrail bars 1 a and 1 b are connected through the receiving portion 20 and are also connected to each other through the dowel 3. Here, in the present embodiment, each wood screw 4 for screwing the handrail rods 1a, 1b to the receiving portion 20 reaches the center of the handrail rods 1a, 1b and is screwed with the dowel 3, so that The rods 1a and 1b, the dowel 3 and the receiving portion 20 of the bracket 2 are screwed together by the two wood screws 4 so as not to be separated. Therefore, in this embodiment, the two handrail bars 1a and 1b can be firmly connected by simply screwing the wood screws 4 and 4 one by one to the handrail bars 1a and 1b.

また、かかる連結構造では、図２〜４に示すように、二本の手摺棒１ａ，１ｂの継ぎ目に、一方の手摺棒１ａの段部１１を底部とする環状の目地溝５が周方向に沿って形成される。このように、二本の手摺棒１ａ，１ｂの継ぎ目に目地溝５を設けて、両手摺棒１ａ，１ｂの外周面の間に間隔を設けておけば、両手摺棒１ａ，１ｂの木目の違いが継ぎ目部分で目立たなくなる。このため、本実施例では、従来構成のように中挟板を介装して手摺棒の継ぎ目を覆わなくても意匠性を確保することができ、少ない部品点数で意匠性に富んだ連結構造を実現できる。 Moreover, in this connection structure, as shown to FIGS. 2-4, the cyclic | annular joint groove | channel 5 which uses the step part 11 of one handrail rod 1a as the bottom at the joint of the two handrail rods 1a and 1b is the circumferential direction. Formed along. In this way, if the joint groove 5 is provided at the joint between the two handrail bars 1a and 1b and a space is provided between the outer peripheral surfaces of the two handrail bars 1a and 1b, the grain of the two handrail bars 1a and 1b The difference is less noticeable at the seam. For this reason, in this embodiment, it is possible to ensure the design without interposing the intermediate plate as in the conventional configuration and covering the joint of the handrail bar, and the connection structure rich in design with a small number of parts. Can be realized.

また、かかる連結構造では、図４に示すように、他方の手摺棒１ｂの端部外周縁から突出する突出部１２が、両手摺棒１ａ，１ｂの端面１０ａ，１０ｂの接合部を外側から覆っている。このため、連結状態にあって、手摺棒１ａ，１ｂの端面同士が密着せずに隙間が生じていても、該隙間が外側に露出して美観を損ねることがない。したがって、かかる連結構造では、突出部１２を設けない構成に比べて、手摺棒１ａ，１ｂの寸法精度を甘くすることができ、また、施工上の許容誤差も大きくなる。すなわち、かかる連結構造によれば、手摺の加工作業や施工作業を簡易なものにできる。 Moreover, in this connection structure, as shown in FIG. 4, the protrusion part 12 which protrudes from the edge part outer periphery of the other handrail stick 1b covers the junction part of the end surfaces 10a and 10b of both handrail bars 1a and 1b from the outer side. ing. For this reason, even if it exists in a connection state and the end surfaces of the handrail rods 1a and 1b are not closely adhered to each other and a gap is formed, the gap is not exposed to the outside and the appearance is not impaired. Therefore, in such a connection structure, the dimensional accuracy of the handrail rods 1a and 1b can be reduced as compared with a configuration in which the protruding portion 12 is not provided, and an allowable error in construction is increased. That is, according to this connection structure, the handrail processing work and construction work can be simplified.

図５は、上記手摺棒の連結構造を適用した手摺Ｒの使用状態説明図である。手摺Ｒは、図５に示すように、手摺Ｒの直線部分を構成する直線状の手摺棒１ａ，１ｂと、入隅部分を構成する屈曲状の手摺棒１ｃと、両端部分を構成する屈曲状の手摺棒１ｄとを、ブラケット２部分で連結して壁面Ｗに固定した構成となっている。かかる手摺Ｒにあって、上記実施例の連結構造は、直線状の手摺棒１ａ，１ｂの連結部分に限らず、全ての手摺棒１ａ〜１ｄの連結部分全般に適用することができる。 FIG. 5 is an explanatory diagram of a use state of the handrail R to which the above-described handrail bar connection structure is applied. As shown in FIG. 5, the handrail R includes straight handrail bars 1 a and 1 b that constitute a straight portion of the handrail R, a bent handrail rod 1 c that constitutes a corner portion, and a bent shape that constitutes both end portions. The handrail rod 1d is connected to the wall surface W by being connected at the bracket 2 portion. In this handrail R, the connection structure of the above embodiment can be applied not only to the connection part of the straight handrail bars 1a and 1b but also to all connection parts of all the handrail bars 1a to 1d.

図６は、上記実施例の構成を一部変更した変形例の連結構造を示す斜視図である。具体的には、かかる構成では、二本の手摺棒１ｅ，１ｅの端面１０ｃ，１０ｃ間には、円板状の中挾板３０が介装される。中挾板３０の中央には貫通孔３２が形成されており、ダボ３を該貫通孔３２に挿通させることにより、ダボ３を手摺棒両端面１０ｃのダボ穴１３に挿入するよう構成されている。両手摺棒１ｅ，１ｅの端面１０ｃには、上記実施例のような段部や突出部は形成されず、手摺棒１ｅの継ぎ目には上記実施例のような目地溝が形成されないが、両手摺棒１ｅ，１ｅの継ぎ目は、中挾板３０の外周部に設けられたフランジ３１によって継ぎ目が目立たないように覆われる。また、ブラケット２の受部２０ａには、中挾板３０のフランジ３１との干渉を避けるために溝状の逃げ部２５が形成される。このように、本考案は、手摺棒１ｅの端面１０ｃの間に中挾板３０を介在させる構成にも適用できる。 FIG. 6 is a perspective view showing a connection structure of a modified example in which the configuration of the above embodiment is partially changed. Specifically, in such a configuration, a disk-shaped intermediate collar plate 30 is interposed between the end faces 10c, 10c of the two handrail bars 1e, 1e. A through hole 32 is formed at the center of the intermediate collar 30, and the dowel 3 is inserted into the dowel hole 13 on both end surfaces 10 c of the handrail bar by inserting the dowel 3 into the through hole 32. . The end surface 10c of the handrail bar 1e, 1e is not formed with a stepped portion or a protruding portion as in the above embodiment, and a joint groove as in the above embodiment is not formed at the joint of the handrail rod 1e. The joints of the rods 1e, 1e are covered with a flange 31 provided on the outer peripheral portion of the intermediate collar plate 30 so that the joints are not conspicuous. Further, a groove-shaped relief portion 25 is formed in the receiving portion 20a of the bracket 2 in order to avoid interference with the flange 31 of the intermediate collar plate 30. Thus, this invention is applicable also to the structure which interposes the intermediate collar board 30 between the end surfaces 10c of the handrail rod 1e.

図７は、上記実施例の構成を一部変更した別の変形例の連結構造を示す斜視図である。具体的には、かかる構成では、ブラケット２の受部２０ｂが、皿状でなく円筒形状をなしている。そして、二本の手摺棒１ｅ，１ｅは、その端部を、受部２０ｂの中に挿入した状態で連結される。両手摺棒１ｅ，１ｅの継ぎ目には、上記実施例のような目地溝は形成されていないが、両手摺棒１ｅ，１ｅの継ぎ目は受部２０ｂによって覆われるため、手摺棒１ｅの継ぎ目が目立つことはない。このように、ブラケットの受部の形状は、実施例から適宜変更することが可能である。 FIG. 7 is a perspective view showing a connection structure of another modification in which the configuration of the above embodiment is partially changed. Specifically, in such a configuration, the receiving portion 20b of the bracket 2 has a cylindrical shape instead of a dish shape. Then, the two handrail bars 1e and 1e are connected with their end portions inserted into the receiving portion 20b. The joint groove of the two handrail bars 1e, 1e is not formed with a joint groove as in the above embodiment, but the joint of the two handrail bars 1e, 1e is covered by the receiving portion 20b, so the joint of the handrail bar 1e is conspicuous. There is nothing. As described above, the shape of the receiving portion of the bracket can be appropriately changed from the embodiment.

なお、本考案の手摺棒の連結構造は、上記実施例の形態に限らず本考案の要旨を逸脱しない範囲内において種々変更を加えることができる。例えば、本考案の手摺棒の連結構造は、図５に例示した手摺Ｒに限られず、屋内外の通路や階段の壁面に取り付けられる手摺全般に好適に採用できる。また、上記実施例は、断面円形の手摺棒１ａ，１ｂの連結構造であるが、本考案は、断面円形の手摺棒に限らず、断面楕円形や断面多角形状の手摺棒の連結構造にも適用可能である。また、上記実施例では、一本のダボ３を両手摺棒１ａ，１ｂの中心に挿入しているが、ダボ３は、手摺棒の中心以外にも挿入可能であり、また、手摺棒の端面に複数本のダボを挿入することも可能である。 In addition, the connection structure of the handrail stick | rod of this invention is not restricted to the form of the said Example, A various change can be added in the range which does not deviate from the summary of this invention. For example, the handrail stick connection structure of the present invention is not limited to the handrail R illustrated in FIG. 5, and can be suitably used for all handrails attached to indoor and outdoor passages and wall surfaces of stairs. Moreover, although the said Example is a connection structure of the handrail sticks 1a and 1b with a circular cross section, this invention is not limited to a handrail bar with a circular cross section but also a connection structure of a handrail bar with a cross-sectional elliptical shape or a polygonal cross section.
