Description

本発明は、手摺り及び手摺り本体に関するものである。 The present invention relates to a handrail and a handrail body.

手摺りには、特許文献１に示すように、基端部が取付け部に取付けられ先端部が基端部から立上がる取付けブラケットと、該取付けブラケットの先端部が取付けられる長尺の芯材と、筒状とされると共にその周方向所定位置において全長に亘って切り離され、その対向する一対の切り離し端部が前記取付けブラケット先端部の厚み方向両面に当接するようにしつつ該芯材を該芯材の全長に亘って覆う被覆材と、を備えたものがある。このものにおいては、一対の切り離し端部が取付けブラケット先端部の厚み方向両面に当接する関係にあることから、その取付けブラケットの非存在領域において、一対の切り離し端部間に、その取付けブラケット先端部の厚みに相当する隙間幅の隙間が手摺りの長手方向に延びるように形成されるものの、その隙間は、当該手摺りを取付けたときには、手摺りの下部に位置して目立たず、見栄えが低下することはない。
特許第３７２９４２７号 As shown in Patent Document 1, the handrail includes a mounting bracket having a base end portion attached to the mounting portion and a tip portion rising from the base end portion, and a long core member to which the tip end portion of the mounting bracket is attached, In addition, the core member is cut out over the entire length at a predetermined position in the circumferential direction thereof, and the core member is placed in the core while the pair of opposed separating end portions are in contact with both sides in the thickness direction of the mounting bracket tip portion. And a covering material covering the entire length of the material. In this case, since the pair of separation end portions are in contact with both sides in the thickness direction of the mounting bracket tip portion, the mounting bracket tip portion is disposed between the pair of separation end portions in the non-existing region of the mounting bracket. Although a gap with a gap width corresponding to the thickness of the rail is formed so as to extend in the longitudinal direction of the handrail, the gap is not conspicuous at the bottom of the handrail when the handrail is attached, and the appearance is reduced. Never do.
Patent No. 3729427

しかし、上記一対の切り離し端部が形成する隙間幅は、取付けブラケット先端部の厚みにより決まることになることから、比較的大きくなる傾向にあり、その隙間に指が嵌り込むおそれがある。このため、その隙間に指が嵌り込むことを防止するべく、その溝にパッキンが嵌め込まれることになっており、部品点数、作業工数の増大を招いている。 However, since the gap width formed by the pair of separated end portions is determined by the thickness of the mounting bracket tip portion, it tends to be relatively large, and there is a possibility that a finger fits into the gap. For this reason, in order to prevent a finger from fitting into the gap, a packing is to be fitted into the groove, resulting in an increase in the number of parts and work man-hours.

本発明は以上のような事情を勘案してなされたもので、その第1の技術的課題は、被覆材の一対の切り離し端部間に隙間が形成される手摺りにおいて、その手摺りが形成する隙間幅を極力短くして指が嵌り込みにくくすることにある。
第２の技術的課題は、上記手摺りに用いられる手摺り本体を提供することにある。 The present invention has been made in view of the above circumstances, and the first technical problem thereof is that the handrail is formed in the handrail in which a gap is formed between the pair of separated end portions of the covering material. It is to make the gap width to be made as short as possible to make it difficult for the fingers to be fitted.
The second technical problem is to provide a handrail body used for the handrail.

A long core material to be attached to the tip of the mounting bracket, and a cylindrical shape, and a state in which it is separated over its entire length at a predetermined position in the circumferential direction, and the pair of opposing separation end portions is the core material In the handrail main body provided with a covering material covering the core material over the entire length of the core material in a state of being locked to
Each of the separation end portions is integrally formed with a projecting piece portion that protrudes from each of the separation end portions and whose tip portion contacts the thickness direction surface of the mounting bracket tip portion,
The wall thickness of each protruding piece is made thinner than the wall thickness of each separating end,
On the both sides in the width direction of the core material, a pair of locking portions are provided over the entire length in the longitudinal direction,
Each of the separation end portions is provided with a bent portion that is bent upward with respect to each of the protruding piece portions and locked to each of the locking portions,
The length from the branch point between the protruding piece part and the bent part to the bent part tip is made longer than the length from the branch point to the protruding piece part tip,
A gap between both ends of the pair of projecting pieces is set to 5 mm or less.

請求項１に係る発明によれば、被覆材として、一対の突片部の両先端間の隙間幅が短いものを用いることにより、取付けブラケットとして、一対の突片部の両先端間の隙間幅に合わせた肉厚のものが用いられたときには、その取付けブラケットの存在領域において、一対の突片部の各先端は取付けブラケットの厚み方向面に当接し、取付けブラケットとして、既存のもの（一対の突片部の両先端間の隙間幅よりも厚いもの）が用いられたときには、その取付けブラケットの存在領域において、一対の突片部を、切り離し端部の肉厚よりも薄い突出形状に基づき、取付けブラケットの厚み方向面に沿って容易に変形させることができる。このため、被覆材として、一対の突片部の両先端間の隙間幅が短いものを用いるだけで、取付けブラケットにおける先端部の厚みがどのようなものであっても、取付けブラケットの非存在領域において、手摺りが形成する隙間幅を極力短くして指が嵌り込みにくくできる。 According to the first aspect of the present invention, as the covering material, a gap width between both ends of the pair of protruding pieces is used as a mounting bracket by using a covering material having a short gap width between both ends of the pair of protruding pieces. When the thickness of the mounting bracket is used, in the region where the mounting bracket is present, the tips of the pair of projecting pieces abut against the thickness direction surface of the mounting bracket, A thicker than the gap width between both ends of the projecting piece portion) is used, in the region where the mounting bracket is present, the pair of projecting piece portions are based on a projecting shape thinner than the wall thickness of the separating end portion, It can be easily deformed along the thickness direction surface of the mounting bracket. For this reason, as the covering material, only the one having a short gap width between the two ends of the pair of projecting pieces is used, and the mounting bracket non-existing region is whatever the thickness of the tip of the mounting bracket. In this case, the gap width formed by the handrail can be made as short as possible to make it difficult for the fingers to be fitted.

請求項２に係る発明によれば、取付けブラケットの厚みが、該取付けブラケットと各折曲部との間に空隙をそれぞれ形成するように薄くされていることから、芯材に被覆材を被せて、被覆材の折曲部を芯材の係止部に係止させる際に、空隙を利用して折曲部の動きを確保できる。このため、芯材に対する被覆材の取付け（係止）を円滑に行うことができる。 According to the invention of claim 2, since the thickness of the mounting bracket is thinned so as to form a gap between the mounting bracket and each bent portion, the core material is covered with the covering material. When the bent portion of the covering material is locked to the locking portion of the core material, the movement of the bent portion can be ensured using the gap. For this reason, attachment (locking) of the covering material to the core material can be performed smoothly.

請求項３に係る発明によれば、芯材に、その幅方向両側において一対の係止部が長手方向全長に亘って設けられ、被覆材に、各切り離し端部に対して上方に分岐されて各係止部に係止する折曲部が設けられていることに基づき、取付けブラケットの非存在領域において、一対の突片部を被覆材の径方向内方に向けて押すと、上記分岐点を中心とした回動力が折曲部に伝達され、折曲部は、芯材の係止部により受け止められる。このとき、突片部と折曲部との分岐点から該折曲部先端までの長さが、該分岐点から該突片部先端までの長さよりも長くされていることから、一対の突片部に付与される押圧力に比して、折曲部を介して係止部に伝達される力を小さくすることができ、これに伴い、係止部から折曲部への反力を小さくできる。このため、一対の突片部に対して指により押圧力を作用させても、それに伴って、折曲部と突片部とが相対的に近づくように変形（回動）することが抑えられることになり、その突片部の変形に基づき隙間幅が拡がることを防止できる。 According to the invention of claim 3, the core member is provided with a pair of locking portions on both sides in the width direction over the entire length in the longitudinal direction, and is branched upward with respect to each separation end portion in the covering material. Based on the fact that the bent portions that are locked to the respective locking portions are provided, in the non-existing region of the mounting bracket, when the pair of projecting pieces are pushed toward the inside in the radial direction of the covering material, the above branch point Is transmitted to the bent portion, and the bent portion is received by the locking portion of the core member. At this time, since the length from the branch point between the projecting piece portion and the bent portion to the tip end of the bent portion is longer than the length from the branch point to the tip end of the projecting piece portion, Compared to the pressing force applied to the one part, the force transmitted to the locking part via the bent part can be reduced, and accordingly, the reaction force from the locking part to the bent part is reduced. Can be small. For this reason, even if a pressing force is applied to the pair of projecting pieces by the finger, it is possible to suppress deformation (rotation) so that the bent portion and the projecting piece are relatively close to each other. In other words, it is possible to prevent the gap width from expanding due to the deformation of the projecting piece.

請求項４に係る発明によれば、折曲部の肉厚が突片部の肉厚よりも厚くされていることから、一対の突片部に対して指により押圧力を作用させても、折曲部が係止部からの反力に基づき反り返ることが、より確実に防止できることになり、一対の突片部の被覆材内方側への変形（撓みに基づく隙間幅拡大）を、一層抑えることができる。 According to the invention according to claim 4, since the thickness of the bent portion is thicker than the thickness of the protruding piece portion, even if a pressing force is applied to the pair of protruding piece portions by a finger, It is possible to more reliably prevent the bent portion from warping based on the reaction force from the locking portion, and the deformation of the pair of projecting pieces to the inner side of the covering material (expansion of the gap width based on the bending) is further enhanced. Can be suppressed.

請求項５に係る発明によれば、一対の突片部が、取付けブラケットの存在領域において、該取付けブラケット先端部の厚み方向両面に案内された状態で変形されていると共に、該取付けブラケットの非存在領域において、該取付けブラケット先端部の肉厚面の対向領域に入り込むように設定されていることから、取付けブラケット先端部の厚みがどのようなものであっても、取付けブラケットの非存在領域において、一対の突片部の両先端間の隙間幅を極めて短くすることができる。 According to the fifth aspect of the present invention, the pair of projecting pieces are deformed while being guided on both sides in the thickness direction of the front end of the mounting bracket in the region where the mounting bracket is present. In the existing area, it is set so as to enter the area opposite to the thick surface of the mounting bracket tip, so whatever the thickness of the mounting bracket tip is, in the non-existing area of the mounting bracket The gap width between both ends of the pair of projecting piece portions can be extremely shortened.

請求項６に係る発明によれば、前記請求項１〜４の作用効果を同時且つ具体的に得ることができる。 According to the invention which concerns on Claim 6, the effect of said Claims 1-4 can be obtained simultaneously and concretely.

請求項７に係る発明によれば、当該手摺り本体を用いることによって、前記請求項1等に係る手摺りを具体的に組み立てることができ、請求項1等に係る発明に用いられる手摺り本体を提供できる。 According to the invention according to claim 7, by using the handrail main body, the handrail according to claim 1 can be specifically assembled, and the handrail main body used in the invention according to claim 1 etc. Can provide.

上記基層部２１は、図１〜図５に示すように、被覆材５の略全体形状（略円筒形状）を形成しており、その基層部２１には、各切り離し端部５ａ（５ｂ）に相当する部分２１ａ（２１ｂ）において、切り離しスリット２０を実質的に区画する突片部２５ａ（２５ｂ）と、芯材４の係止部１７ａ，１７ｂに係止させるための折曲部２４ａ（２４ｂ）とが突出するようにして一体的に形成されている。各突片部２５ａ（２５ｂ）は、その肉厚が、被覆材５の周方向において、先端に向かうほど薄くなる先細形状に形成されている。本実施形態においては、突片部２５ａ（２５ｂ）は、その外面が、外形を構成する被覆材５の大部分の曲率と同じにされて、その突片部２５ａ（２５ｂ）の外面が被覆材５の他の部分の外面に滑らかに連続されている一方、その内面は、先端に向かうに従って外面との肉厚が薄くなるように設定されている。すなわち、図５において、基層部２１の大部分の肉厚をｄ１、突片部２５ａ（２５ｂ）の基端側の肉厚をｄ２、突片部２５ａ（２５ｂ）の先端の肉厚をｄ３とすると、ｄ１＞ｄ２＞ｄ３の関係が成立している。また、一対の突片部２５ａ，２５ｂ間の切り離しスリット２０の幅に関しては、本実施形態においては、その両先端が取付けブラケット３の厚み方向面に対して、連結部３１よりも延び方向内方側部分（符号２６をもって示す）において当接する長さに設定されている。具体的には、常温（硬化状態）で、指が入り込まない５ｍｍ以下（好ましくは４ｍｍ前後）に設定されている。 The said base layer part 21 forms the substantially whole shape (substantially cylindrical shape) of the coating | covering material 5, as shown in FIGS. 1-5, The base layer part 21 has each cutting | disconnection edge part 5a (5b). In a corresponding portion 21a (21b), a protruding piece portion 25a (25b) that substantially divides the separation slit 20 and a bent portion 24a (24b) for locking to the locking portions 17a and 17b of the core member 4 are provided. Are integrally formed so as to protrude. Each protruding piece 25a (25b) is formed in a tapered shape whose thickness becomes thinner toward the tip in the circumferential direction of the covering material 5. In the present embodiment, the projecting piece portion 25a (25b) has the outer surface made the same as the curvature of most of the covering material 5 constituting the outer shape, and the outer surface of the projecting piece portion 25a (25b) is the covering material. While it continues smoothly on the outer surface of the other part of 5, the inner surface is set so that the thickness with the outer surface becomes thinner toward the tip. That is, in FIG. 5, the thickness of the most part of the base layer 21 is d1, the thickness of the base end side of the projecting piece 25a (25b) is d2, and the thickness of the tip of the projecting piece 25a (25b) is d3. Then, a relationship of d1> d2> d3 is established. Further, regarding the width of the separation slit 20 between the pair of projecting piece portions 25a and 25b, in the present embodiment, both ends thereof extend inward in the direction extending from the connecting portion 31 with respect to the thickness direction surface of the mounting bracket 3. The length is set to abut on the side portion (indicated by reference numeral 26). Specifically, it is set to 5 mm or less (preferably around 4 mm) at which the finger does not enter at room temperature (cured state).

上記各折曲部２４ａ（２４ｂ）は、図４，図５に示すように、突片部２５ａ（２５ｂ）に対して分岐した状態で中空部１４内（上方側）に向けて折曲されている。この折曲部２４ａ（２４ｂ）と突片部２５ａ（２５ｂ）との分岐点Ｏからその折曲部２４ａ（２４ｂ）先端までの長さＬ１が、分岐点Ｏから突片部２５ａ（２５ｂ）先端までの長さＬ２よりも長くされている。しかも、折曲部２４ａ（２４ｂ）の肉厚ｄ４は、略全体的に、突片部２５ａ（２５ｂ）の肉厚ｄ２，ｄ３よりも太くなっている。この両折曲部２４ａ，２４ｂ外面は、対向した状態で離間されており、本実施形態においては、この一対の折曲部２４ａ，２４ｂ間の間隔は、常温において、取付けブラケット３の連結部３１の厚みｔと略同じ程度に設定されている。 As shown in FIGS. 4 and 5, each of the bent portions 24 a (24 b) is bent toward the inside (upper side) of the hollow portion 14 in a state branched from the projecting piece portion 25 a (25 b). Yes. The length L1 from the branch point O between the bent portion 24a (24b) and the protruding piece portion 25a (25b) to the tip of the bent portion 24a (24b) is the tip of the bent piece portion 25a (25b). It is made longer than length L2. Moreover, the thickness d4 of the bent portion 24a (24b) is substantially larger than the thickness d2, d3 of the protruding piece portion 25a (25b). The outer surfaces of the bent portions 24a and 24b are spaced apart from each other. In the present embodiment, the distance between the pair of bent portions 24a and 24b is the connecting portion 31 of the mounting bracket 3 at room temperature. Is set to be approximately the same as the thickness t.

前記外層部２２は、図２〜図５に示すように、表面層として、突片部２５ａ（２５ｂ）の外周面を含む基層部２１の外周面（折曲部２４ａ，２４ｂを除く）を覆っている。この外層部２２の肉厚は、基層部２１の肉厚に比べて格段に薄くなっている。本実施形態においては、外層部２２が設けられているが、外層部２２を設けずに、基層部２１だけで被覆材５を形成してもよい。 As shown in FIGS. 2 to 5, the outer layer portion 22 covers the outer peripheral surface (excluding the bent portions 24 a and 24 b) of the base layer portion 21 including the outer peripheral surface of the projecting piece portion 25 a (25 b) as a surface layer. ing. The thickness of the outer layer portion 22 is much thinner than the thickness of the base layer portion 21. In the present embodiment, the outer layer portion 22 is provided, but the covering material 5 may be formed only by the base layer portion 21 without providing the outer layer portion 22.

上記基層部２１及び外層部２２の各硬さは、外層部２２の硬さが基層部２１の硬さ以上にされている。本実施形態においては、基層部２１の硬さ、外層部２２の硬さのいずれもが「Ｈｓ９４ＪＩＳＡ」に設定されている。この硬さに関しては、ＪＩＳＫ６３０１「加硫ゴム物理試験方法」のスプリング式Ａ型硬度計を用い、０〜１００の数値で表した。勿論、この外層部２２及び基層部２１の硬さに関して、手摺り使用者が的確に把持できる点が考慮されている。 The hardness of the base layer portion 21 and the outer layer portion 22 is such that the hardness of the outer layer portion 22 is greater than the hardness of the base layer portion 21. In the present embodiment, both the hardness of the base layer portion 21 and the hardness of the outer layer portion 22 are set to “Hs94 JIS A”. This hardness was represented by a numerical value of 0 to 100 using a spring type A hardness tester of JIS K 6301 “Physical Test Method for Vulcanized Rubber”. Of course, regarding the hardness of the outer layer portion 22 and the base layer portion 21, a point that a handrail user can accurately grasp is taken into consideration.

このような被覆材５は、芯材４の外周面をその全長に亘って包み込むように覆っている。この場合、その被覆材５における一対の突片部２５ａ，２５ｂは、取付けブラケット先端部３ａ（当接部分２６）の厚み方向両面に当接され、その被覆材５の各折曲部２４ａ，２４ｂは、被覆材５が芯材４に対して相対回転することを規制すべく、芯材４の各係止部１７ａ，１７ｂに係止されている。しかも、取付けブラケット３における脚部８先端部（連結部３１下方側）と各折曲部２４ａ（２４ｂ）との間には、脚部８の肉厚が先端側に向かうに従って薄くなる構成に基づき、空隙３０が形成されている。 Such a covering material 5 covers the outer peripheral surface of the core material 4 so as to wrap around the entire length thereof. In this case, the pair of projecting piece portions 25a and 25b in the covering material 5 are brought into contact with both sides in the thickness direction of the mounting bracket tip portion 3a (contact portion 26), and the bent portions 24a and 24b of the covering material 5 are contacted. Are locked to the locking portions 17 a and 17 b of the core material 4 in order to restrict the covering material 5 from rotating relative to the core material 4. In addition, the thickness of the leg portion 8 is reduced between the distal end portion of the mounting bracket 3 (the lower side of the connecting portion 31) and the bent portions 24a (24b) toward the distal end side. A void 30 is formed.

次に、当該手摺り２の取付け作業について、主として図３に基づいて説明する。
先ず、壁面１Ａに取付けブラケット３を所定間隔毎に取付ける。各取付けブラケット３の取付け作業は、取付けブラケット３の基端部７を壁面１Ａに沿わせつつアンカーボルト９とナット１０とを用いることにより行い、このとき、取付けブラケット３の先端部３ａが上方側に向くようにする。 Next, the attachment work of the handrail 2 will be described mainly based on FIG.
First, the attachment bracket 3 is attached to the wall surface 1A at predetermined intervals. Each mounting bracket 3 is mounted by using the anchor bolt 9 and the nut 10 while keeping the base end portion 7 of the mounting bracket 3 along the wall surface 1A. At this time, the distal end portion 3a of the mounting bracket 3 is located on the upper side. Try to face.

次に、壁面１Ａに取付けられた取付けブラケット３（複数の取付けブラケット３）に対して、芯材４を取付ける。この取付けにおいては、壁面１Ａに取付けられた複数の取付けブラケット３の先端部３ａに芯材４を被せ、取付けブラケット３の各先端部３ａを芯材４の中空部１４内に挿入溝１５を介して挿入することにより、その取付けブラケット３の連結部３１を上壁部１１の保持溝１６に嵌合させる。その上で、取付けねじ１９を、横方向から芯材４及び取付けブラケット３の連結部３１にねじ込み、芯材４と取付けブラケット３とを一体化する。 Next, the core member 4 is attached to the mounting bracket 3 (a plurality of mounting brackets 3) attached to the wall surface 1A. In this attachment, the core material 4 is covered with the tip portions 3a of the plurality of mounting brackets 3 attached to the wall surface 1A, and each tip portion 3a of the mounting bracket 3 is inserted into the hollow portion 14 of the core material 4 via the insertion groove 15. The connecting portion 31 of the mounting bracket 3 is fitted into the holding groove 16 of the upper wall portion 11. Then, the mounting screw 19 is screwed into the connecting portion 31 of the core material 4 and the mounting bracket 3 from the lateral direction, and the core material 4 and the mounting bracket 3 are integrated.

次に、上記芯材４（取付けブラケット３に取付けられたもの）に対して、被覆材５を取付ける。この取付けにおいては、先ず、被覆材５を温めて柔らかくし、一対の突片部２５ａ，２５ｂ等を押し開く。その上で、その開かれた切り離しスリット２０から芯材４に被覆材５を被覆する。このとき、芯材４の円弧面１８は、一対の突片部２５ａ，２５ｂを押し開き、芯材４の被覆材５内への入り込みを助ける。またこのとき、図４の仮想線で示すように、脚部８の肉厚が先端側に向かうに従って薄くなる構成に基づき形成される空隙３０により、各折曲部２４ａ，２４ｂの動き（係止部１７ａ，１７ｂに係止させる方向への動き）が確保され、その動きが取付けブラケット３の脚部８により阻害されることはない。これにより、被覆材５は、芯材４を包み込むように被覆し、その被覆材５の各折曲部２４ａ，２４ｂは、芯材４の各係止部１７ａ，１７ｂに係止される。この結果、芯材４と被覆材５とが一体化することになり、当該手摺り２の取付け作業は終了する。このとき、本実施形態においては、被覆材５における一対の突片部２５ａ，２５ｂは、図２に示すように、取付けブラケット３先端部の当接部分２６に当接された状態となる。勿論、この温めて柔らかくした被覆材５は、常温に戻ることにより硬化する。 Next, the covering material 5 is attached to the core material 4 (attached to the mounting bracket 3). In this attachment, first, the covering material 5 is warmed and softened, and the pair of projecting pieces 25a, 25b and the like are pushed open. Then, the covering material 5 is coated on the core material 4 from the opened cut slit 20. At this time, the circular arc surface 18 of the core material 4 pushes open the pair of projecting pieces 25a and 25b, and helps the core material 4 enter the coating material 5. At this time, as indicated by the phantom line in FIG. 4, the movement (locking) of the bent portions 24a and 24b is caused by the gap 30 formed based on the configuration in which the thickness of the leg portion 8 becomes thinner toward the distal end side. Movement in the direction of engagement with the portions 17a and 17b) is ensured, and the movement is not hindered by the legs 8 of the mounting bracket 3. Thereby, the covering material 5 covers the core material 4 so as to wrap, and the bent portions 24 a and 24 b of the covering material 5 are locked to the locking portions 17 a and 17 b of the core material 4. As a result, the core material 4 and the covering material 5 are integrated, and the installation work of the handrail 2 is completed. At this time, in the present embodiment, the pair of projecting piece portions 25a and 25b in the covering material 5 are in contact with the contact portion 26 at the tip of the mounting bracket 3 as shown in FIG. Of course, the warmed and softened coating material 5 is cured by returning to room temperature.

したがって、この第１実施形態においては、取付けブラケット３の厚みが、一対の突片部２５ａ，２５ｂとの当接部分２６において、該当接部分２６以外の部分に比して薄くされていることから、被覆材として、一対の突片部２５ａ，２５ｂ間の切り離しスリット２０の幅をその取付けブラケット３の厚みに応じた狭いものを用いることができ、これに伴い、手摺り２において、一対の突片部２５ａ，２５ｂ間における切り離しスリット２０の幅を、取付けブラケット３の非存在領域で簡単に短くできる。 Therefore, in the first embodiment, the thickness of the mounting bracket 3 is made thinner in the contact portion 26 with the pair of projecting piece portions 25a and 25b than in the portion other than the corresponding contact portion 26. Further, as the covering material, a narrow slit 20 between the pair of projecting piece portions 25a and 25b can be used according to the thickness of the mounting bracket 3, and accordingly, the handrail 2 has a pair of protrusions. The width of the separation slit 20 between the pieces 25a and 25b can be easily shortened in the region where the mounting bracket 3 is not present.

また、芯材４に対する被覆材５の取付けにおいては、被覆材５を温めて一対の突片部２５ａ，２５ｂが押し開かれるように柔らかくされるが、一対の突片部２５ａ，２５ｂに関しては、その際、その先細形状（他の部分よりも肉厚が薄くなっていること）に基づき、取付けブラケット３の厚み方向面に馴染み易い性質（取付けブラケット３の厚み方向面に沿って容易に変形させ易い性質）を有している。このため、手摺り２における切り離しスリット２０の幅を、取付けブラケットの非存在領域において上記の場合よりも格段に短くしたいとき（切り離しスリット２０の幅を限りなく０にしたいときを含む）には、被覆材５として、一対の突片部２５ａ，２５ｂ間の切り離しスリット２０の幅を、上記場合よりもさらに短くしたもの（切り離しスリット２０の幅が０のものを含む）を用いることができる。これにより、手摺り２において、一対の突片部２５ａ，２５ｂは、図６，図７に示すように、取付けブラケット３の存在領域において、取付けブラケット３先端部の厚み方向両面に案内された状態で変形され、取付けブラケット３の非存在領域においては、取付けブラケット３先端部（当接部２６）の肉厚面の対向領域に入り込むことになる。この結果、取付けブラケット３の非存在領域においては、一対の突片部２５ａ，２５ｂの切り離しスリット２０の幅が、前記場合よりもさらに短くなり、指が一対の切り離しスリット２０間に入り込むことを確実に防止できる。 Further, in attaching the covering material 5 to the core material 4, the covering material 5 is warmed and softened so that the pair of projecting piece portions 25a and 25b are pushed open, but with respect to the pair of projecting piece portions 25a and 25b, At that time, based on the tapered shape (thickness is thinner than other parts), it is easy to adapt to the thickness direction surface of the mounting bracket 3 (easily deformed along the thickness direction surface of the mounting bracket 3). Easy nature). For this reason, when it is desired to make the width of the separation slit 20 in the handrail 2 much shorter than in the above case in the non-existing region of the mounting bracket (including the case where the width of the separation slit 20 is desired to be zero as much as possible) As the covering material 5, one in which the width of the separation slit 20 between the pair of projecting piece portions 25 a and 25 b is further shorter than that in the above case (including one in which the width of the separation slit 20 is 0) can be used. Thereby, in the handrail 2, as shown in FIGS. 6 and 7, the pair of projecting piece portions 25a and 25b are guided to both sides in the thickness direction of the front end portion of the mounting bracket 3 in the region where the mounting bracket 3 exists. In the non-existing region of the mounting bracket 3, it enters into the opposing region of the thick surface of the tip of the mounting bracket 3 (abutting portion 26). As a result, in the non-existing region of the mounting bracket 3, the width of the separation slit 20 of the pair of projecting pieces 25 a and 25 b is further shorter than in the above case, and it is ensured that the finger enters between the pair of separation slits 20. Can be prevented.

さらに、一対の突片部２５ａ，２５ｂを含む被覆材５全体が、押出成形により一体的に成形されており、被覆材５全体を簡単に形成できると共に、その一体化強度も高めることができる。 Further, the entire covering material 5 including the pair of projecting piece portions 25a and 25b is integrally formed by extrusion molding, so that the entire covering material 5 can be easily formed and its integrated strength can be increased.

また、芯材４に一対の係止部１７ａ，１７ｂが長手方向全長に亘って設けられ、被覆材５に一対の折曲部２４ａ，２４ｂが設けれていることから、取付けブラケット３の非存在領域において、一対の突片部２５ａ，２５ｂを被覆材５の径方向内方に向けて押すと、折曲部２４ａ（２４ｂ）と突片部２５ａ（２５ｂ）の分岐点Ｏを中心とした回動力（図４中、矢印参照）が折曲部２４ａ（２４ｂ）に伝達され、折曲部２４ａ（２４ｂ）の回動力は、芯材４の係止部１７ａ（１７ｂ）により受け止められる。このとき、分岐点Ｏから折曲部２４ａ（２４ｂ）先端までの長さＬ１が、分岐点Ｏから突片部２５ａ（２５ｂ）先端までの長さＬ２よりも長くされ、モーメント腕に関し、折曲部２４ａ（２４ｂ）の方が突片部２５ａ（２５ｂ）よりも長くされていることから、突片部２５ａ（２５ｂ）に付与される押圧力に比して、折曲部２４ａ（２４ｂ）を介して係止部１７ａ（１７ｂ）に伝達される力を小さくすることができ、これに伴い、係止部１７ａ（１７ｂ）から折曲部２４ａ（２４ｂ）への反力を小さくできる。このため、突片部２５ａ（２５ｂ）に対して指により押圧力を作用させても、それに伴って、折曲部２４ａ（２４ｂ）と突片部２５ａ（２５ｂ）とが相対的に互いに近づくように変形（回動）することが抑えられることになり、その突片部２５ａ（２５ｂ）の変形（撓み）に基づき切り離しスリット２０の幅が拡がることが防止される。しかもこの場合、折曲部２４ａ（２４ｂ）の肉厚ｄ４が突片部２５ａ（２５ｂ）の肉厚ｄ２，ｄ３よりも厚くされていることから、一対の突片部２５ａ（２５ｂ）に対して指により押圧力を作用させても、折曲部２４ａ（２４ｂ）が係止部１７ａ（１７ｂ）からの反力に基づき相対的に反り返ることが、より確実に防止されることになり、一対の突片部２５ａ（２５ｂ）の被覆材５内方側への変形（撓みに基づく隙間幅拡大）を、一層抑えることができる。このように、切り離しスリット２０の幅を狭くするだけでなく、突片部２５ａ（２５ｂ）の変形（撓み）を抑制することによっても、指が切り離しスリット２０を介して入り込むことを防止できる。 Further, since the core member 4 is provided with a pair of locking portions 17a and 17b over the entire length in the longitudinal direction, and the covering material 5 is provided with the pair of bent portions 24a and 24b, the mounting bracket 3 is not present. In the region, when the pair of projecting piece portions 25a and 25b are pushed inward in the radial direction of the covering material 5, the rotation around the branch point O between the bent portion 24a (24b) and the projecting piece portion 25a (25b) is performed. The power (see the arrow in FIG. 4) is transmitted to the bent portion 24a (24b), and the turning force of the bent portion 24a (24b) is received by the locking portion 17a (17b) of the core member 4. At this time, the length L1 from the branch point O to the tip of the bent portion 24a (24b) is made longer than the length L2 from the branch point O to the tip of the projecting piece 25a (25b), Since the part 24a (24b) is made longer than the projecting piece part 25a (25b), the bent part 24a (24b) is formed in comparison with the pressing force applied to the projecting piece part 25a (25b). Thus, the force transmitted to the locking portion 17a (17b) can be reduced, and accordingly, the reaction force from the locking portion 17a (17b) to the bent portion 24a (24b) can be reduced. For this reason, even if a pressing force is applied to the projecting piece portion 25a (25b) with a finger, the bent portion 24a (24b) and the projecting piece portion 25a (25b) are relatively close to each other accordingly. Therefore, the width of the separation slit 20 is prevented from expanding based on the deformation (deflection) of the projecting piece 25a (25b). In addition, in this case, the thickness d4 of the bent portion 24a (24b) is thicker than the thickness d2 and d3 of the protruding piece portion 25a (25b), so that the pair of protruding piece portions 25a (25b) Even if a pressing force is applied by a finger, the bent portion 24a (24b) is more reliably prevented from being warped relatively based on the reaction force from the locking portion 17a (17b). Deformation of the projecting piece 25a (25b) toward the inner side of the covering material 5 (expansion of the gap width based on bending) can be further suppressed. Thus, not only the width of the separation slit 20 is narrowed but also the finger can be prevented from entering through the separation slit 20 by suppressing the deformation (deflection) of the projecting piece 25a (25b).

図８は第２実施形態を示す。この第２実施形態において、前記第１実施形態と同一構成要素については同一符号を付してその説明を省略する。 FIG. 8 shows a second embodiment. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

図８に示す第２実施形態は、取付けブラケット３の変形例を示している。この第２実施形態に係る取付けブラケット３においては、その脚部８の肉厚ｔが先端側に向かうに従って徐々に薄くなるのではなく、脚部８の上下方向略半分の位置よりも上側部分がそれよりも下側部分に比して細くされており、この取付けブラケット３を用いても、前記第１実施形態同様の作用効果を得ることができる。 The second embodiment shown in FIG. 8 shows a modification of the mounting bracket 3. In the mounting bracket 3 according to the second embodiment, the thickness t of the leg portion 8 is not gradually reduced toward the distal end side, but the upper portion of the leg portion 8 is positioned at a position approximately half the vertical direction. It is made thinner than the lower part, and even if this mounting bracket 3 is used, the same effect as the first embodiment can be obtained.

このように、取付けブラケット３として、一対の突片部２５ａ（２５ｂ）が当接する当接部分２６の肉厚を薄くしたものを用いることは好ましい。しかし、被覆材５として、一対の突片部２５ａ，２５ｂ間の切り離しスリット２０の幅を狭くしたものを用いる状態の下で、その一対の突片部２５ａ（２５ｂ）の先細形状（変形容易性、馴染み性）を利用することにより、取付けブラケット３の非存在領域において切り離しスリット２０を狭くすることができる（図６，図７参照）。このため、取付けブラケット３の非存在領域において切り離しスリット２０を狭くするに際して、必ずしも取付けブラケット３の肉厚が制約事項となるものではない。 As described above, it is preferable to use the mounting bracket 3 having a reduced thickness of the contact portion 26 with which the pair of projecting piece portions 25a (25b) contact. However, the taper shape (easiness of deformation) of the pair of projecting piece portions 25a (25b) is used as the covering material 5 in a state where the width of the separation slit 20 between the pair of projecting piece portions 25a and 25b is reduced. ), The separation slit 20 can be narrowed in the non-existing region of the mounting bracket 3 (see FIGS. 6 and 7). For this reason, when the separation slit 20 is narrowed in the non-existing region of the mounting bracket 3, the thickness of the mounting bracket 3 is not necessarily a restriction.

尚、本発明の目的は、明記されたものに限らず、実質的に好ましい或いは利点として記載されたものに対応したものを提供することをも含むものである。 It should be noted that the object of the present invention is not limited to what is explicitly described, but includes provision of what is substantially preferable or corresponding to what is described as an advantage.
