Description

本発明は、歩行者が掴む箇所に弾性を有する手摺に関するものである。 The present invention relates to a handrail having elasticity at a place where a pedestrian grips.

例えば、特開２０１２−１２２２９５号公報に開示されるような手摺では、手で掴む部位である外覆部材が弾性を有する素材で成形されている。 For example, in a handrail as disclosed in Japanese Patent Application Laid-Open No. 2012-122295, an outer covering member that is a part to be grasped by a hand is formed of an elastic material.

特開２０１２−１２２２９５号公報JP 2012-122295 A

上記のような手摺は、歩行者が掴んだときに、外覆部材が弾性を有することにより、手に柔らかな感触を得られるものであった。しかしながら、このような手摺は、金属製の芯材の外周に外覆部材を配置する構造であることから、芯材の角部の外周部と外覆部材とが密接に当接する。これにより、芯材と外覆部材との接触箇所は弾性を失って固くなることから、手摺を掴んだときの触り心地が非常に悪くなり、さらに、歩行者が手摺を掴んだときに滑りやすくなって安定性も失われてしまう。したがって、この種の手摺本来の機能が充分に発揮されない問題点があった。
本発明は、上記課題を鑑みてなされたものであり、歩行者が掴んだときに柔らかな感触を充分に得られるとともに、使用時の安定性を確保できる手摺を提供することにある。 The handrail as described above has a soft feel to the hand because the outer covering member has elasticity when a pedestrian grips it. However, since such a handrail has a structure in which an outer cover member is disposed on the outer periphery of a metal core member, the outer peripheral portion of the corner portion of the core member and the outer cover member are in close contact with each other. As a result, the contact portion between the core member and the outer covering member loses elasticity and becomes hard, so the touch feeling when gripping the handrail becomes very bad, and furthermore, when the pedestrian grips the handrail, it is slippery. As a result, stability is lost. Therefore, there is a problem that the original function of this type of handrail is not fully exhibited.
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a handrail that can sufficiently obtain a soft feel when a pedestrian grips it and can ensure stability during use.

本発明のうち請求項１記載の発明は、芯材と、外覆部材と、支持部材とを備えており、外覆部材は、弾性を有するとともに芯材の外周を覆うものであり、支持部材は、芯材及び躯体への固定部をそれぞれ有しており、躯体から芯材を持ち出して支持するものであり、芯材は、外覆部材と当接する外周部を肉抜きして空隙形成部を設け、外覆部材と芯材との間に空隙を形成し、外覆部材は、その周壁の一部が長手方向に連続して分断する断面ほぼＣ字状をなしており、外覆部材の周壁の分断された両端部には、係合部がそれぞれ設けてあり、周壁と係合部とで、周壁の分断部の反対側に向けて開口する溝部を形成していて、溝部は開口側から底側に向けて拡幅する蟻溝としてあり、芯材は、支持部材の取付溝を有しており、取付溝の縁部に沿って被係合部が設けてあり、被係合部は、取付溝側に向けて屈曲しかつ先端側に向けて拡幅する蟻型としてあり、外覆部材の溝部に嵌まり、係合部を係合するものであることを特徴とする。 The invention according to claim 1 of the present invention includes a core member, an outer cover member, and a support member. The outer cover member has elasticity and covers the outer periphery of the core member. has a fixed part of the core material and the precursor, respectively, which supports brought out the core member from the precursor, the core is an outer peripheral portion abutting on the outer covering member and the lightening gap forming portion A gap is formed between the outer cover member and the core member, and the outer cover member has a substantially C-shaped cross section in which a part of the peripheral wall is continuously divided in the longitudinal direction. Engagement portions are provided at both divided ends of the peripheral wall, and a groove portion that opens toward the opposite side of the peripheral wall separation portion is formed by the peripheral wall and the engagement portion. It is a dovetail groove that widens from the side to the bottom side, and the core material has a mounting groove for the support member, along the edge of the mounting groove An engaged portion is provided, and the engaged portion has a dovetail shape that bends toward the mounting groove side and widens toward the distal end side, and fits into the groove portion of the outer cover member to engage the engaging portion. It is characterized by being compatible .

本発明のうち請求項２記載の発明では、前記溝部は、溝の両側壁面のうち係合部側の側壁面が開口方向に対して平行であり、外覆部材の周壁側の側壁面が開口方法に傾斜していることを特徴とする。 According to a second aspect of the present invention , in the groove portion, the side wall surface on the engaging portion side of the both side wall surfaces of the groove is parallel to the opening direction, and the side wall surface on the peripheral wall side of the outer cover member is opened. Inclined in the way.

本発明のうち請求項１記載の発明によれば、芯材は、外覆部材と当接する外周部を肉抜きして空隙形成部を設け、芯材と外覆部材との間に空隙が形成される。これにより、手摺を掴んだときに、手に柔らかな感触が得られ掴み心地が向上するとともに、指が手摺の外覆部材へ弾性的に食い込むことによる手摺の安定性を確保することができる。また、外覆部材の溝部は開口側から底側に向けて拡幅する蟻溝としてあり、芯材の被係合部は、取付溝側に向けて屈曲しかつ先端側に向けて拡幅する蟻型としてあり、外覆部材の溝部に嵌まり、係合部を係合するため、芯材から外覆部材が外れにくい。 According to the first aspect of the present invention, the core material is provided with a gap forming portion by hollowing out the outer peripheral portion in contact with the outer cover member, and a void is formed between the core material and the outer cover member. Is done . As a result, when the handrail is gripped, a soft feel can be obtained in the hand , and the gripping comfort can be improved, and the stability of the handrail can be ensured by the finger elastically biting into the outer cover member of the handrail. The groove portion of the outer cover member is a dovetail groove that widens from the opening side toward the bottom side, and the engaged portion of the core member is bent toward the mounting groove side and widens toward the tip side. Since it fits into the groove of the outer cover member and engages the engaging portion, the outer cover member is unlikely to come off from the core material.

本発明のうち請求項２記載の発明によれば、前記溝部は、溝の両側壁面のうち係合部側の側壁面が開口方向に平行であることから、被係合部が係合部を乗り越えやすくしてあるので、外覆部材を芯材に取り付けやすい。また、外覆部材の周壁側の側壁面は傾斜して蟻溝状としてあることで、請求項１と同様、芯材へ取り付けた後に外覆部材が外れにくい構造となる。 According to the second aspect of the present invention, since the groove portion has a side wall surface on the engaging portion side of both side wall surfaces of the groove that is parallel to the opening direction, the engaged portion includes the engaging portion. Since it is easy to get over, it is easy to attach the outer cover member to the core. Further, the side wall surface on the peripheral wall side of the outer cover member is inclined and formed in a dovetail shape, so that the outer cover member does not easily come off after being attached to the core material as in the first aspect.

以下、本発明の手摺の実施形態を図面に基づいて説明する。
本実施による手摺は、図１と図４に示すように、室内通路の躯体壁（支持体）Ｗに取り付けたものである。また、本手摺は、図１と図２（ａ）〜（ｄ）に示すように、芯材１と、外覆部材２と、支持部材３とから構成してある。 Hereinafter, embodiments of the handrail of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 4, the handrail according to the present embodiment is attached to a housing wall (support) W of the indoor passage. Moreover, this handrail is comprised from the core material 1, the outer covering member 2, and the supporting member 3, as shown to FIG. 1 and FIG. 2 (a)-(d).

支持部材３は、図１を参照すれば、躯体壁Ｗに固定する躯体固定部３ａと芯材１に固定する芯材固定部３ｂをそれぞれ有しており、躯体固定部３ａから芯材固定部３ｂが通路側に持ち出されたほぼＬ字型をなしている。そして、上記の躯体固定部３ａをネジなどの固定具で躯体壁Ｗに固定したときに、支持部材３の芯材固定部３ｂが通路側に突出する。 Referring to FIG. 1, the support member 3 includes a housing fixing portion 3 a that is fixed to the housing wall W and a core material fixing portion 3 b that is fixed to the core material 1, and the core fixing portion is formed from the housing fixing portion 3 a. 3b has a substantially L-shape brought out to the passage side. And when said housing fixing | fixed part 3a is fixed to the housing wall W with fixing tools, such as a screw, the core material fixing | fixed part 3b of the supporting member 3 protrudes to the channel | path side.

外覆部材２は、図２（ｃ）（ｄ）のように、弾性を備えるように樹脂の押出成形により形成してある。また、上記の外覆部材２は、その周壁の一部が長手方向に連続して分断する断面ほぼＣ字状をなしており、さらに、外覆部材２の周壁の分断された両端部には、周壁内周側に向かって突出した鉤状をなす係合部２ａ，２ａがそれぞれ設けてある。そして、係合部２ａ，２ａは、後述するが芯材１の被係合部４，４にそれぞれ係合することができる。 As shown in FIGS. 2C and 2D, the outer cover member 2 is formed by resin extrusion so as to have elasticity. In addition, the outer cover member 2 has a substantially C-shaped cross section in which a part of the peripheral wall is continuously divided in the longitudinal direction. , Engaging portions 2a and 2a each having a hook shape protruding toward the inner peripheral side of the peripheral wall are provided. The engaging portions 2a and 2a can be engaged with engaged portions 4 and 4 of the core material 1 as described later.

芯材１は、図２（ａ）（ｂ）のように、長尺な中空押出形材からなっており、その断面形状は、ほぼ円形のソリッド形状をなしている。また、芯材１の開口部が支持部材３の取付溝５を形成している。また、芯材１の内周部には、取付溝５から挿入された支持部材３の被取付部を有している。さらに、芯材１の取付溝５の縁部に沿って被係合部４，４が設けてある。被係合部４，４は、外覆部材２の係合部２ａ，２ａを係合して、芯材１から外覆部材２が外れにくい構造としている。さらに、芯材１の外周部のうち、上側部と、左右両側部と、取付溝５を挟んだ両側部のそれぞれの箇所を肉抜きして空隙形成部Ｒを有している。上記の芯材１の被係合部４，４に、外覆部材２の係合部２ａ，２ａを係合して外覆部材２で芯材１の外周を覆うことで、外覆部材２と芯材１の間に空隙形成部Ｒを設けた各箇所で複数の空隙Ｓが形成される。また、上記の芯材１と外覆部材２との取り付けは、芯材１の外周部に外覆部材２を被せ、芯材１の被係合部４，４の長手方向のほぼ全長に亘って外覆部材２の係合部２ａ，２ａを係合することで完成する。これにより、図３のように歩行者が手摺を掴んだときに手Ｈの触れる外覆部材２が、上記の各空隙Ｓのある複数の箇所で弾性変形して凹み、歩行者が掴んだ手Ｈと指Ｐが外覆部材２の外周部に柔らかく食い込む。 As shown in FIGS. 2 (a) and 2 (b), the core material 1 is formed of a long hollow extruded shape, and the cross-sectional shape thereof is a substantially circular solid shape. Further, the opening of the core material 1 forms the mounting groove 5 of the support member 3. Further, the inner peripheral portion of the core member 1 has a portion to be attached to the support member 3 inserted from the attachment groove 5. Furthermore, engaged portions 4 and 4 are provided along the edge of the mounting groove 5 of the core material 1. The engaged portions 4, 4 have a structure in which the outer covering member 2 is not easily detached from the core member 1 by engaging the engaging portions 2 a, 2 a of the outer covering member 2. Furthermore, among the outer peripheral part of the core material 1, each of the upper side part, the left and right side parts, and the both side parts sandwiching the mounting groove 5 is thinned to have a gap forming part R. The outer cover member 2 is formed by engaging the engaging portions 2 a and 2 a of the outer cover member 2 with the engaged portions 4 and 4 of the core member 1 and covering the outer periphery of the core member 1 with the outer cover member 2. A plurality of voids S are formed at each location where the void forming portion R is provided between the core material 1 and the core material 1. Further, the core member 1 and the outer cover member 2 are attached by covering the outer periphery of the core member 1 with the outer cover member 2 over substantially the entire length in the longitudinal direction of the engaged portions 4 and 4 of the core member 1. This is completed by engaging the engaging portions 2a, 2a of the outer cover member 2. As a result, the outer covering member 2 that the hand H touches when the pedestrian grips the handrail as shown in FIG. 3 is elastically deformed and recessed at a plurality of locations having the gaps S, and the pedestrian grips the hand. H and fingers P softly bite into the outer periphery of the outer cover member 2.

上記のように構成される支持部材３、外覆部材２、芯材１の各構成部材で手摺を形成することにより、以下に示す作用、効果を奏する。
図３のように、外覆部材２と芯材１との間に形成された空隙Ｓにより、歩行者が本実施による手摺の外覆部材２を掴んだときに、指Ｐのいずれかで空隙Ｓを覆う外覆部材２の外周部を押さえることになる。これにより、歩行者は、手摺を掴んだときに外覆部材２から弾力のある柔らかな感触が得られる。さらに、本実施による手摺は、芯材１の下部両側の箇所をそれぞれ肉抜きして形成した空隙形成部Ｒがあり、外覆部材２における支持部材３の挿し込まれている両側の箇所に空隙Ｓがそれぞれ設けられている。このことから、歩行者が手摺を掴んだときに、押圧力が最もかかる指Ｐの先が外覆部材２の外周部にかかる箇所に空隙Ｓが設けられる。したがって、歩行者が手摺を掴んだときに、芯材１の固い感触を伝えることがなく、手摺を掴んだときの柔らかな感触のよさと、指Ｐの先が手摺の外覆部材２へ弾性的に食い込むことによる手摺本来の安定性の両方を確保することができる。 By forming the handrail with the constituent members of the support member 3, the outer cover member 2, and the core member 1 configured as described above, the following operations and effects are achieved.
As shown in FIG. 3, when the pedestrian grips the outer cover member 2 of the handrail according to the present embodiment by the gap S formed between the outer cover member 2 and the core material 1, the gap is detected with any of the fingers P. The outer peripheral part of the outer covering member 2 covering S is pressed down. Thereby, the pedestrian can obtain a soft and elastic feel from the outer covering member 2 when holding the handrail. Further, the handrail according to the present embodiment has a gap forming portion R formed by hollowing out the portions on both sides of the lower portion of the core material 1, and the gaps are formed on both sides of the outer cover member 2 where the support member 3 is inserted. S is provided. From this, when the pedestrian grips the handrail, the gap S is provided at a place where the tip of the finger P to which the pressing force is most applied is applied to the outer peripheral portion of the outer covering member 2. Therefore, when the pedestrian grasps the handrail, the hard feeling of the core material 1 is not transmitted, the soft feel when the handrail is grasped, and the tip of the finger P is elastic to the outer member 2 of the handrail. Therefore, both the original stability of the handrail by biting in can be ensured.

本発明の手摺は、上記実施形態で説明した歩行者の進路に沿って配置されるほぼ一直線状の手摺の他、通路の方向や段差等に対応して取り付けるコーナー用の手摺にも適用できる。また、芯材１は、上記実施形態では断面ほぼ円形状の形材を肉抜きしたものであるが、外覆部材２との間に空隙Ｓが形成される形状であればよい。さらに、芯材１と外覆部材２との間に形成される空隙Ｓは、少なくとも歩行者の指Ｐの先にかかる箇所に設けてあればよい。また、外覆部材２の材質についても、上記実施形態では塩化ビニル樹脂を使用しているが、一般的なこの種の手摺に適した弾性や耐候性、耐久性、可撓性を有する素材であれば、素材を限定するものではない。支持部材３は、手摺と支持体Ｗとの距離を保ち、歩行者が手摺を掴みやすくするものであればよい。また、支持体Ｗは、上記実施形態では躯体壁に手摺を設けてあるが、通路から起立する支柱に手摺を設けてもよい。 The handrail of the present invention can be applied to a handrail for a corner that is attached corresponding to the direction or step of the passage in addition to the substantially straight handrail arranged along the path of the pedestrian described in the above embodiment. In the above embodiment, the core material 1 is a material having a substantially circular cross section. However, the core material 1 only needs to have a shape in which a gap S is formed between the core material 1 and the outer cover member 2. Furthermore, the space S formed between the core material 1 and the outer covering member 2 may be provided at least at a place on the tip of the pedestrian's finger P. As for the material of the outer cover member 2, vinyl chloride resin is used in the above embodiment. However, the outer cover member 2 is made of a material having elasticity, weather resistance, durability, and flexibility suitable for this general handrail. If there is, the material is not limited. The support member 3 may be any member that maintains the distance between the handrail and the support W and makes it easier for a pedestrian to grasp the handrail. Moreover, although the support body W has provided the handrail in the housing wall in the said embodiment, you may provide a handrail in the support | pillar which stands up from a channel | path.
