Description

本発明は、手すりとして使用される手すり部材に関し、特にその断面構造に係る。 The present invention relates to a handrail member used as a handrail, and particularly relates to its cross-sectional structure.

手すりは人が歩行する際の支えに、あるいは立ち上がる際に手で握り、体を支えるものであるから強度が必要であり、その一方で人が手で握る際にソフト感が要求される。
そこで、芯材に樹脂からなる被覆部材で覆う構造のものが提案されている。
例えば、特許文献１に笠木芯材の外周開口部に被覆体の両端部を係止させるように組み付けた手すり笠木を開示する。
しかし、このような手すり部材にあっては、同公報図５に示すように下方に開放部を有するため、指や物等が挟まる恐れがあり、危険である。
また、人が握った際にソフト感を付与しようとして、軟らかい樹脂を採用すると、手で握った際にＣ断面形状の被覆部材にねじれが生じ、芯材から外れる恐れがあることから、一般に硬質又は半硬質の樹脂材が使用されている。
しかし、そのような硬い樹脂では、常温の状態で開放部を開いて組付けることはできないため、ヒーター等で加温し、軟化させながら組み付けなければならず、組み付け作業が大変であった。
また、硬い樹脂のため、手触り感が悪い問題も残る。 Handrails are used to support a person when walking or when they stand, and support the body, so strength is necessary. On the other hand, a person needs a soft feeling when grasping by hand.
Therefore, a structure in which the core material is covered with a coating member made of resin has been proposed.
For example, Patent Document 1 discloses a handrail headboard assembled so that both ends of a covering body are locked to an outer peripheral opening of a headboard core material.
However, such a handrail member is dangerous because it has an open portion below as shown in FIG.
In addition, if a soft resin is used to give a soft feeling when a person grasps it, the covering member having a C cross-sectional shape may be twisted when it is grasped by hand, and may be detached from the core material. Alternatively, a semi-hard resin material is used.
However, such a hard resin cannot be assembled by opening the open part at room temperature, so it must be assembled while being heated and softened with a heater or the like, and the assembling work has been difficult.
Moreover, since it is hard resin, the problem that a touch feeling is bad remains.

本発明は、被覆部材が芯材から外れにくく、組み付けが容易で手触り感の良好な手すり部材の提供を目的とする。 An object of the present invention is to provide a handrail member in which the covering member is difficult to come off from the core material, is easy to assemble, and has a good touch feeling.

本発明に係る手すり部材は、芯材と前記芯材を被覆した被覆部材を備え、前記被覆部材は前記芯材に組付けるために拡径及び開口する端部を長手方向に沿って有し、前記開口する両側の端部は組み付け後に相互に係止し、当該被覆部材が閉断面形状になる係止部を有することを特徴とする。
ここで、被覆部材の開口する両側の端部が相互に係止するとは、端部同士が開かないように相互にこの端部が干渉することをいう。
よって、爪状の係止部でもよく、また一方の端部が他方の端部に設けた凹部に嵌合する形態でもよい。
また芯材は、強度面から金属製であるのが好ましい。 The handrail member according to the present invention includes a core member and a covering member that covers the core member, and the covering member has an end portion that expands and opens in the longitudinal direction for assembly to the core member, The ends on both sides of the opening are locked to each other after assembly, and the covering member has a locking portion having a closed cross-sectional shape.
Here, the fact that the ends on both sides where the covering member opens are mutually locked means that the ends interfere with each other so that the ends do not open.
Therefore, it may be a claw-shaped locking portion, or one end portion may be fitted into a recess provided in the other end portion.
The core material is preferably made of metal from the viewpoint of strength.

本発明において、芯材は前記被覆部材の組み付け時に被覆部材の前記一方の端部に係合するための係合部を有するようにしてもよい。
このようにすると、被覆部材の長手方向に沿って開口した一方の端部を芯材の係合部に係合させることができるので、他方の端部を広げるようにして芯材に組み付ける際に、被覆部材が回るようにずれるのを防止し、組み付けが容易になる。 In the present invention, the core member may have an engaging portion for engaging with the one end portion of the covering member when the covering member is assembled.
If it does in this way, since one edge part opened along the longitudinal direction of the covering member can be engaged with the engaging part of a core material, when assembling to a core material so that the other edge part may be expanded , Prevents the covering member from slipping off and facilitates assembly.

本発明において、被覆部材は樹脂製であり前記係止部が他の一般部よりも硬い樹脂製であってもよい。
このようにすると、被覆部材の硬い端部が芯材の係合部に強固に嵌合し芯材に組み付けやすく外れにくい。
また、係止部以外の一般部を軟らかいソフト感のある樹脂を用いることもでき、手触り感が良くなる。 In the present invention, the covering member may be made of resin, and the locking portion may be made of resin harder than other general portions.
If it does in this way, the hard edge part of a coating | coated member will fit firmly in the engaging part of a core material, it will be easy to assemble | attach to a core material, and will not come off easily.
In addition, a soft and soft resin can be used for the general part other than the locking part, and the touch feeling is improved.

本発明において、前記芯材は金属芯と当該金属芯の外周部に配設した樹脂芯からなるとともに折り曲げ可能であり、前記樹脂芯に前記係合部を有するようにしてもよい。
このようにすると、曲げが必要な手すりのコーナー部に適用できる。 In the present invention, the core material may be formed of a metal core and a resin core disposed on an outer peripheral portion of the metal core and bendable, and the resin core may have the engaging portion.
If it does in this way, it can apply to the corner part of the handrail which needs bending.

本発明に係る手すり部材は、芯材に組み付け後の被覆部材の断面が閉断面になるので、手指等が挟まる恐れがない。
また、組み付け後に被覆部材が閉断面になるので、ねじれて外れることが無くなり、ソフト感のある軟らかい樹脂を用いることができ、芯材に被覆部材の開口部を室温で広げて組み付けることができるので、組み付け作業も容易になる。 In the handrail member according to the present invention, the cross-section of the covering member after assembling to the core member becomes a closed cross-section, so that there is no possibility that fingers or the like are caught.
In addition, since the covering member has a closed cross section after assembly, it is not twisted off and soft resin with a soft feeling can be used, and the opening of the covering member can be expanded and assembled to the core material at room temperature. Assembling work becomes easy.

（ａ）〜（ｆ）は芯材に被覆部材を組み付ける流れを示す。(A)-(f) shows the flow which attaches a covering member to a core material. 曲げコーナー部の実施例を示す。The example of a bending corner part is shown. （ａ）〜（ｅ）に曲げコーナー部の使用例を示す。(A) to (e) show usage examples of the bending corner portion.

本発明に係る手すり部材の構造例を以下図に基づいて説明するが、本発明はこれに限定されない。 Although the structural example of the handrail member concerning this invention is demonstrated based on a figure below, this invention is not limited to this.

図１（ａ）は、樹脂材からなる被覆部材２０の断面を示す。
断面Ｃ型形状の軟質部２４の一方の端部に、相対的に硬質材からなる嵌合端部２１を有し、他方の端部にこれも一般部の軟質部２４より相対的に硬質材からなる係止端部２２を有する。
この嵌合端部２１に係止端部２２が係止することで、図１（ｆ）に示すように係止部（Ａ）が形成される。 Fig.1 (a) shows the cross section of the coating | coated member 20 which consists of resin materials.
One end of the soft part 24 having a C-shaped cross section has a fitting end 21 made of a relatively hard material, and the other end is also harder than the soft part 24 of the general part. It has the latching end part 22 which consists of.
When the engaging end portion 22 is engaged with the fitting end portion 21, an engaging portion (A) is formed as shown in FIG.

軟質部はＪＩＳＫ７２１５のＡ形硬度６０〜８５程度が好ましく、また表面の意匠部とその内側のコア部の多層構造でもよい。
コア部に軟らかいソフト感のある樹脂を選定し、表面の意匠部をそれよりも硬い樹脂を採用し、汚れが付着しにくいものがよい。
嵌合端部２１と係止端部２２とは、ＪＩＳＫ７２１５のＡ形硬度９０〜１００程度のものがよい。
これにより、図１（ａ）に矢印で示したように、常温（室温）にて嵌合端部２１と係止端部２２とを把持し、拡径するように広げることができる。 The soft portion preferably has a JIS K 7215 A-type hardness of about 60 to 85, and may have a multilayer structure of a design portion on the surface and a core portion on the inside thereof.
A soft and soft resin is selected for the core part, and a harder resin is used for the design part of the surface so that dirt is less likely to adhere.
The fitting end portion 21 and the locking end portion 22 are preferably those having a JIS K 7215 A-type hardness of about 90-100.
Thereby, as shown by the arrow in FIG. 1A, the fitting end portion 21 and the locking end portion 22 can be gripped at room temperature (room temperature) and can be expanded so as to increase in diameter.

図１（ｂ）に、金属材を用いてフォーミング成形した芯材１０の断面図を示す。
芯材１０は、建築物の壁面や床面から立設したブラケットの先端部を差し込むためでもある開口した係合部１１を有する。
