Description

本発明は、手すりを取り付けるための手すりブラケットに関し、さらに詳しくは、先端に手すりを固定するための手すり受けを、基端に座板を有する支持腕を、左右一対の2つに分離された形態としたものに関する。   The present invention relates to a handrail bracket for attaching a handrail, and more specifically, a handrail receiver for fixing a handrail to a distal end, a support arm having a seat plate at a base end, and a pair of left and right separated forms About what

手すりを取り付けるための手すりブラケットにおいて、左右一対の支持腕を所定の距離を置いて離隔して配置されたものが(例えば、特許文献1参照)、また、前記支持腕を途中から接合させたものが(例えば、特許文献2参照)、さらに、左右一対の支持腕を接合して溶接などで固定したもの(例えば、特許文献3参照)などが、提案されている。   A handrail bracket for attaching a handrail, in which a pair of left and right support arms are spaced apart by a predetermined distance (for example, see Patent Document 1), and the support arms are joined from the middle (For example, refer to Patent Document 2), and a pair of left and right support arms joined together and fixed by welding or the like (for example, refer to Patent Document 3) have been proposed.

特開2008−308904号公報(段落0010、図1(c)〜(d)等)Japanese Patent Laying-Open No. 2008-308904 (paragraph 0010, FIGS. 1 (c) to (d), etc.)

特開2009−019434号公報(特許請求の範囲、図2等)JP 2009-019434 A (Claims, FIG. 2 etc.)

しかしながら、前記特許文献1,2に示すものはいずれも左右一対の支持腕の基端部を1つの座板に溶接などで一体的としてあって、左右一対の支持腕は分離された形態ではなく、しかも、壁への締め付けが左右一対の支持腕の間に位置しているため、強度的に好ましくない。強度を上げるため、締め付けピッチを大きく取ろうとすると、手すりブラケットが大型化してしまい、意匠的、コスト面で不利である。   However, in both of Patent Documents 1 and 2, the base end portions of the pair of left and right support arms are integrated with one seat plate by welding or the like, and the pair of left and right support arms are not separated. Moreover, since the fastening to the wall is located between the pair of left and right support arms, it is not preferable in terms of strength. If the fastening pitch is increased to increase the strength, the handrail bracket is increased in size, which is disadvantageous in terms of design and cost.

一方、前記特許文献3に示すものは、左右一対の支持腕が密着しているため、これもまた強度的に不利である。   On the other hand, the one shown in Patent Document 3 is disadvantageous in terms of strength because the pair of left and right support arms are in close contact.

このような手すりブラケットにより手すりを支えた場合には、手すりに掛かる荷重を充分に支えることができないと思われる。なぜならば、左右一対の支持腕の離間距離を余り大きくすることができない分、手すりに掛かる荷重を支える力もそれだけ弱くなるからである。左右一対の支持腕の離間距離を大きくすればするほど、手すりに掛かる荷重を支える力も大きくなる。   When the handrail is supported by such a handrail bracket, it seems that the load applied to the handrail cannot be sufficiently supported. This is because the force for supporting the load applied to the handrail becomes weaker as much as the distance between the pair of left and right support arms cannot be increased too much. The greater the distance between the pair of left and right support arms, the greater the force that supports the load on the handrail.

本発明は、上記欠点を解消することを目的として開発されたものであって、先端に手すりを固定するための手すり受けを有し、基端に座板を有する支持腕を、左右一対の2つに分離された形態とし、左右一対の前記2つの支持腕を互いに固定するためのものであって、少なくとも左右一対の2つの支持腕を覆うカバーに形成されていて、前記2つの支持腕間に介装させ得る取付座からなる定着手段を備えていることを特徴とするものである。
本発明によれば、左右一対の2つの支持腕を前記カバーで覆った状態で、左右一対の2つの支持腕を左右に離して配置することができるので、左右一対の2つの支持腕が離れていない場合に比べて、手すりに掛かる荷重を支える強度を上げることができる。例えば、図に示すように、左右一対の2つの支持腕が中心位置からLだけ離れた位置において、手すりに荷重Fが負荷された場合を想定すると、手すりを支えている左右一対の2つの支持腕が間隔wで配置されていて前記荷重Fを負担している同図(a)の場合の方が、離れていない同図(b)の場合に比べて、強度・剛性の面で優れていることは明らかである。
The present invention has been developed for the purpose of eliminating the above-described drawbacks, and has a handrail support for fixing a handrail at the distal end, and a support arm having a base plate at the base end. A pair of left and right support arms that are separated from each other and formed on a cover that covers at least the pair of left and right support arms. It is characterized by comprising fixing means comprising a mounting seat that can be interposed between the fixing seats .
According to the present invention, since the pair of left and right two support arms are covered with the cover, the pair of left and right pair of support arms can be spaced apart from each other. Compared with the case where it is not , the strength which supports the load applied to the handrail can be increased. For example, as shown in FIG. 3 , assuming that a load F is applied to the handrail at a position where the pair of left and right two support arms are separated from the center position by L, the pair of left and right supporting the handrail In the case of Fig. 7 (a) where the supporting arms are arranged at intervals w and bear the load F, the strength and rigidity are superior to the case of Fig. 9 (b) where they are not separated. It is clear that

また、本発明によれば、2つの支持腕を左右一対の2つに分離された形態としてあるので、手すり受けに取り付けた手すりが安定するのみならず、手すり受けへの手すりの取付施工性も良い。   In addition, according to the present invention, since the two support arms are separated into a pair of left and right, the handrail attached to the handrail receiver is not only stable, but also the workability of attaching the handrail to the handrail receiver is good.

左右一対の2つの支持腕間に介装させ得る取付座が上下に2つ備えられていることが望ましい。この場合には、左右一対の2つの支持腕を上下2つの取付座で上下とも均等に左右に離して配置することができるので、左右一対の2つの支持腕が離れていない場合に比べて、手すりに掛かる荷重を支える強度を上げることができる。   It is desirable that two upper and lower mounting seats that can be interposed between a pair of left and right support arms are provided. In this case, a pair of left and right two support arms can be equally spaced apart from the top and bottom with two upper and lower mounting seats, so compared to the case where the pair of left and right two support arms are not separated, The strength to support the load applied to the handrail can be increased.

請求項1記載の発明によれば、左右一対の2つの支持腕を前記カバーで覆った状態で、左右一対の2つの支持腕を左右に離して配置することができるので、左右一対の2つの支持腕が離れていない場合に比べて、手すりに掛かる荷重を支える強度を上げることができる。また、2つの支持腕を左右一対の2つに分離された形態としてあるので、手すり受けに取り付けた手すりが安定するのみならず、手すり受けへの手すりの取付施工性も良い。 According to the first aspect of the present invention, since the pair of left and right support arms can be separated from each other in a state where the pair of left and right support arms are covered with the cover, Compared with the case where the supporting arm is not separated, the strength for supporting the load applied to the handrail can be increased. In addition, since the two support arms are separated into a pair of left and right, the handrail attached to the handrail receiver is not only stabilized, but also the workability of attaching the handrail to the handrail receiver is good.

請求項2記載の発明によれば、左右一対の2つの支持腕を上下2つの取付座で上下とも均等に左右に離して配置することができるので、左右一対の2つの支持腕が離れていない場合に比べて、手すりに掛かる荷重を支える強度を上げることができる。 According to the second aspect of the present invention, it is possible you to place a pair of left and right two support arms up and down both away to the left and right equally in two upper and lower mounting seat, a pair of left and right two support arms away Compared with the case where there is not, the strength which supports the load applied to the handrail can be increased.

壁に取り付けられる形式の手すりブラケットの一例であって、左右一対の2つの支持腕を互いに固定するための定着手段に、少なくとも左右一対の2つの支持腕を覆うカバーに形成されていて、前記2つの支持腕間に介装させ得る取付座を用いた場合を例示するもので、 (a)は分解斜視図、(b)は少なくとも左右一対の2つの支持腕をカバーで覆った状態を示す斜視図、(c)はその正面図、(d)はその側面図、(e)は左右一対の支持腕の先端にそれぞれ設けてある手すり受けをカバーの一部で覆った場合において、手すり受けの外側に位置するカバーの一部で手すりを安定して支えることができることを示す断面図である。It is an example of a handrail bracket of the type that is attached to a wall, and is formed on a fixing means for fixing a pair of left and right support arms to each other, and a cover that covers at least the pair of left and right support arms. This is an example in which a mounting seat that can be interposed between two support arms is used, (a) is an exploded perspective view, and (b) is a perspective view showing a state in which at least a pair of left and right support arms are covered with a cover. (C) is a front view thereof, (d) is a side view thereof, (e) is a handrail receiver when the handrail receiver provided at the tip of the pair of left and right support arms is covered with a part of the cover. It is sectional drawing which shows that a handrail can be stably supported by a part of cover located outside. 壁に取り付けられる形式の手すりブラケットの一例であって、図の場合とは異なって、左右一対の2つの支持腕間に介装させ得る取付座が上下に2つ備えられている場合を例示するもので、(a)は分解斜視図、(b)は少なくとも左右一対の2つの支持腕をカバーで覆った状態を示す斜視図、(c)はその正面図、(d)はその側面図である。It is an example of the handrail bracket of the type attached to a wall, Comprising: Unlike the case of FIG. 1 , the case where the two mounting seats which can be interposed between two left-right paired support arms is provided is illustrated. (A) is an exploded perspective view, (b) is a perspective view showing a state where at least two pairs of left and right support arms are covered with a cover, (c) is a front view thereof, and (d) is a side view thereof. It is. 左右一対の2つの支持腕が中心位置からLだけ離れた位置で、手すりに荷重Fが負荷された場合において、手すりを支えている左右一対の前記2つの支持腕が間隔wで配置されている同図(a)の場合の方が、離れていない同図(b)の場合に比べて、手すり受けに取り付けた手すりが安定するのみならず、手すり受けへの手すりの取付施工性が良いことと、強度・剛性の面で優れていることを説明するための原理図である。When the load F is applied to the handrail at a position where the pair of left and right two support arms are separated from the center position by L, the pair of left and right support arms supporting the handrail are arranged at an interval w. In the case of Fig. (A), compared to the case of Fig. (B) that is not separated, the handrail attached to the handrail receiver is not only stable, but also the handrail mounting to the handrail receiver is better. It is a principle diagram for explaining that it is excellent in terms of strength and rigidity.

本発明による手すりブラケットの一例を、図面に基いて詳細に説明する。本手すりブラケットは壁に取り付けられる形式のものと、壁及び笠木に取り付けられる直受け形式のものとがある。図1には、壁に取り付けられる形式のものであって、左右一対の2つの支持腕を互いに固定するための定着手段に、少なくとも左右一対の2つの支持腕を覆うカバーに形成されていて、前記2つの支持腕間に介装させ得る取付座を用いた場合を示すなお、壁及び笠木に取り付けられる直受け形式の手すりブラケットについては、図示を省略するAn example of a handrail bracket according to the present invention will be described in detail with reference to the drawings. The handrail bracket is of a type that can be attached to the wall, or a type of direct receiving type that can be attached to the wall and headboard. FIGS. 1 and 2 are of a type attached to a wall, and are formed on a fixing means for fixing a pair of left and right support arms to each other and on a cover covering at least the pair of left and right support arms. have been, that shows an example case where a mounting seat which can be interposed between the two support arms. In addition, about the handrail bracket of the direct receiving type attached to a wall and a headboard , illustration is abbreviate | omitted .

図1には、壁に取り付けられる形式の手すりブラケットの一例であって、左右一対の2つの支持腕1,1を互いに固定するための定着手段に、少なくとも左右一対の2つの支持腕1,1を覆うカバー6に形成されていて、前記2つの支持腕1,1間に介装させ得る取付座6aを用いた場合を例示する。左右一対の2つの支持腕1,1の先端には手すりCを固定するための手すり受け1aが、基端には座板1bが備えられており、両支持腕1,1を左右一対の2つに分離された形態としてある。このような形態とすると、手すり受け1a,1aに取り付けた手すりCが安定するのみならず、手すり受け1a,1aへの手すりCの取付施工性も良い。 FIG. 1 shows an example of a handrail bracket of a type that is attached to a wall, and at least a pair of left and right support arms 1 and 1 are used as fixing means for fixing the pair of left and right support arms 1 and 1 to each other. The case where the attachment seat 6a which is formed in the cover 6 which covers and can be interposed between the two support arms 1 and 1 is illustrated. A pair of left and right two support arms 1 and 1 are provided with a handrail receiver 1a for fixing the handrail C, and a base plate is provided with a seat plate 1b. It is a separate form. If it is set as such a form, the handrail C attached to the handrail receivers 1a and 1a will not only become stable, but the installation workability of the handrail C to the handrail receivers 1a and 1a is also good.

その理由を図に基づいて説明する。同図(a)に示すように、手すりCを支えている左右一対の2つの支持腕1,1が間隔wで配置されている場合には、左右2つの手すり受け1a,1aの幅a’は支持腕1’,1’が離れていない同図(b)の幅b’の場合よりwだけ大きい。したがって、このwだけ大きい幅を有する左右2つの手すり受け1a,1aに取り付けた手すりCが安定する。また、手すりCを左右2つの手すり受け1a,1aに取り付けるに当っては、手すり受け1a,1aに手すりCを仮置きした状態の下にねじで締結するが、その際、左右2つの手すり受け1a,1aの幅がwだけ大きい同図(a)の場合の方が、支持腕1’,1’が離れていない同図(b)の場合に比べて、左右2つの手すり受け1a,1aから手すりCが落下する可能性が低いので、それだけ手すり受け1a,1aへの手すりCの取付施工性も良いということができる。 It will be described with reference to the reason in FIG. As shown in FIG. 5A, when a pair of left and right support arms 1 and 1 supporting the handrail C are arranged at a distance w, the width a ′ of the two left and right handrail receivers 1a and 1a. Is larger by w than in the case of the width b ′ in FIG. Therefore, the handrail C attached to the left and right handrail receivers 1a and 1a having a width larger by w is stabilized. Further, when attaching the handrail C to the left and right handrail receivers 1a, 1a, the handrail C is fastened with screws under the condition that the handrail C is temporarily placed on the handrail receivers 1a, 1a. In the case of the same figure (a) where the width of 1a, 1a is larger by w, the two left and right handrail receivers 1a, 1a are compared to the case of the same figure (b) where the supporting arms 1 ', 1' are not separated. Since the possibility that the handrail C falls from the bottom is low, it can be said that the installation workability of the handrail C to the handrail receivers 1a and 1a is also good.

そして、例えば、同図に示すように、左右一対の2つの支持腕1,1と1’,1’が中心位置からLだけ離れた位置において、手すりCに荷重Fが負荷された場合を想定する。この場合において、同図(a)の場合には、手すりCを支えている左右一対の2つの支持腕1,1が間隔wで配置されている。これに対して、同図(b)の場合には、左右一対の2つの支持腕1’,1’が離れてなくて接合されている。この場合を対比すると、左右一対の前記2つの支持腕1,1が間隔wで配置されていて離れている両支持腕1,1で前記荷重Fを負担している同図(a)の場合の方が、離れていない同図(b)の場合に比べて、強度・剛性の面で優れていることは明らかである。 Then assume, for example, as shown in the figure, a pair of right and left two support arms 1, 1 1 ', 1' in the away from the center position by L position, where the load F is loaded to the handrail C To do. In this case, in the case of FIG. 5A, a pair of left and right support arms 1 and 1 supporting the handrail C are arranged at an interval w. On the other hand, in the case of FIG. 5B, the pair of left and right support arms 1 ′ and 1 ′ are joined without being separated. In comparison with this case, the pair of left and right two support arms 1 and 1 are arranged at a distance w and the two support arms 1 and 1 are separated from each other and bear the load F in the case of FIG. It is clear that this is superior in terms of strength and rigidity compared to the case of FIG.

なぜならば、手すりCに同じ荷重Fを負荷した場合、左右一対の2つの支持腕1,1がwだけ離れている図(a)のA−A端面の場合の方が、左右一対の2つの支持腕1’,1’が離れてなくて接合されている図(b)のB−B端面の場合より曲がりにくい。すなわち、前者の場合の方が、後者に比べて剛性が強いということができる。したがって、荷重Fの値を上げて行った場合において、左右一対の2つの支持腕1’,1’が離れてなくて接合されている図(b)の場合の方が、塑性変形又は破壊されやすく、左右一対の2つの支持腕1,1がwだけ離れている図(a)の場合の方が、強度が強いということができる。 This is because, when loaded with the same load F railings C, towards the case of the A-A end face of Figure 3 a pair of left and right two support arms 1,1 are separated by w (a) is a pair of left and right 2 one of the support arms 1 ', 1' is less likely to bend than that of B-B end surface shown in FIG. 3 (b) are joined without away. That is, it can be said that the former case is stronger than the latter. Accordingly, in a case where performed to raise the value of the load F, a pair of left and right two support arms 1 ', 1' towards the case of FIG. Are joined without away 3 (b), the plastic deformation or fracture it is easy, towards the case of FIG. 3 that a pair of left and right two support arms 1,1 are separated by w (a) is, it can be said that strength is high.

手すりCは、左右2つの手すり受け1a,1aにねじ(図示省略)で固定することができ、また、前記両座板1b,1bに形成された2つの孔にそれぞれ挿通した2本の壁固定用のねじ3を用いて、左右一対の2つの支持腕1,1を図示していない壁に固定することができる。   The handrail C can be fixed to the left and right handrail receivers 1a and 1a with screws (not shown), and is fixed to two walls respectively inserted into two holes formed in the both seat plates 1b and 1b. The pair of left and right support arms 1 and 1 can be fixed to a wall (not shown) by using the screw 3 for use.

(a)に示すように、左右一対の2つの支持腕1,1と左右2つの手すり受け1a,1aと左右2つの座板1b,1bとを覆う上下2つ割りのカバー6,6のうちの上側のカバー6に、前記2つの支持腕1,1間に介装させ得る取付座6aが形成されている。 As shown in FIG. 1 (a) , a pair of left and right covers 6, 6 covering a pair of left and right support arms 1, 1 and two left and right handrail receivers 1a, 1a and two left and right seat plates 1b, 1b. A mounting seat 6 a that can be interposed between the two support arms 1 and 1 is formed on the upper cover 6.

この場合においても、少なくとも左右一対の2つの支持腕1,1を上下2つ割りのカバー6,6で覆うとともに、前記2つの支持腕1,1間に前記取付座6aを介装し、この取付座6aに形成されているねじ挿通孔6a’にねじ6bを挿通して締結することにより、左右一対の2つの支持腕1,1を前記取付座6aの幅だけ離した状態で、すなわち、左右一対の2つの支持腕1,1を所定の離間距離を置いた状態で互いに固定することができる。このように、左右一対の2つの支持腕1,1を離れた位置に配置することにより、手すりCに掛かる荷重を支える強度を上げることができる。   Also in this case, at least a pair of left and right two support arms 1 and 1 are covered with two upper and lower covers 6 and 6, and the mounting seat 6 a is interposed between the two support arms 1 and 1. By inserting and fastening the screw 6b into the screw insertion hole 6a 'formed in the mounting seat 6a, the pair of left and right support arms 1, 1 are separated by the width of the mounting seat 6a, that is, The pair of left and right support arms 1 and 1 can be fixed to each other with a predetermined distance. In this way, by arranging the pair of left and right two support arms 1 and 1 at positions separated from each other, the strength for supporting the load applied to the handrail C can be increased.

1に示すように、本手すりブラケットには着脱プレート5が用いられており、ねじ4,4を座板1bに形成されたねじ挿通孔1c,1cを介して着脱プレート5のねじ孔5a,5aにそれぞれ螺着することにより、左右一対の2つの支持腕1,1の座板1b,1bを、1枚の着脱プレート5に定着させることができる。その状態を図(b)に斜視図で、同図(c)に正面図で、同図(d)に側面図でそれぞれ示す。なお、前記着脱プレート5の3つの孔にそれぞれ挿通した3本の壁固定用のねじ3を用いて、左右一対の2つの支持腕1,1を図示していない壁に固定することができる。 As shown in FIG. 1, a detachable plate 5 is used for the handrail bracket, and screws 4 and 4 are screwed through holes 1c and 1c formed in the seat plate 1b through screw holes 5a, The seat plates 1b and 1b of the pair of left and right support arms 1 and 1 can be fixed to the single detachable plate 5 by being screwed to 5a. The state in a perspective view in FIG. 1 (b), a front view in FIG. (C), respectively in side view in FIG. (D). Note that using three screws 3 for the wall fixing of the respectively inserted into the three holes of the detachable plate 5, Ru can be fixed to a wall (not shown) a pair of left and right two support arms 1, 1 .

に示すように、少なくとも左右一対の2つの支持腕1,1を上下2つ割りのカバー6,6で覆った場合において、手すり受け1aで手すりCを受けたとき、同図(e)に示すように、手すり受け1aの外側にカバー6の一部6cが位置するので、外側に位置するカバー6の一部6cでも手すりCを安定して支えることができるし、締結時に手すりCを支えやすい。例えば、同図(e)に示すように、手すり受け1aのみで手すりCを支えた場合の手すりCを受け得る幅xに比べて、前記カバー6の一部6cを含む部分で手すりCを支えた場合には、同図Xで示すように、少なくとも前記幅xよりも広い幅で手すりCを支えることができる。 As shown in FIG. 1 , when at least a pair of left and right support arms 1 and 1 are covered with upper and lower split covers 6 and 6, when handrail C is received by handrail receiver 1a, FIG. As shown in FIG. 3, since the part 6c of the cover 6 is located outside the handrail receiver 1a, the handrail C can be stably supported by the part 6c of the cover 6 located outside, and the handrail C can be supported at the time of fastening. Easy to support. For example, as shown in FIG. 5 (e), the handrail C is supported by the portion including the part 6c of the cover 6 as compared with the width x that can receive the handrail C when the handrail C is supported only by the handrail receiver 1a. In this case, as shown in FIG. X, the handrail C can be supported with a width wider than at least the width x.

では、左右一対の2つの支持腕1,1と左右2つの手すり受け1a,1aと左右2つの座板1b,1bとを覆う上下2つ割りのカバー6,6のうちの上側のカバー6に、前記2つの支持腕1,1間に介装させ得る取付座6aが形成されているのに対して、図には、左右一対の2つの支持腕1,1間に固定させ得る取付座6aが上下に2つ備えられている場合を例示する。左右一対の2つの支持腕1,1の先端には手すりCを固定するための手すり受け1aが、基端には座板1bが備えられており、両支持腕1,1を左右一対の2つに分離された形態としてあることは、図1、図2とも同様である。 In FIG. 1 , the upper cover of the upper and lower split covers 6, 6 covering the pair of left and right support arms 1, 1, the left and right handrail receivers 1 a, 1 a and the left and right seat plates 1 b, 1 b. 6, a mounting seat 6a that can be interposed between the two support arms 1 and 1 is formed, whereas in FIG. 2 , it can be fixed between a pair of left and right support arms 1 and 1. The case where the two mounting seats 6a are provided up and down is illustrated. A pair of left and right two support arms 1 and 1 are provided with a handrail receiver 1a for fixing the handrail C, and a base plate is provided with a seat plate 1b. that there as a separate form One, Figure 1, is the same both FIG.

(a)はその分解斜視図であって、左右一対の2つの支持腕1,1と左右2つの手すり受け1a,1aと左右2つの座板1b,1bとを覆う上下2つ割りのカバー6,6のうちの上側のカバー6に、前記2つの支持腕1,1間に介装させ得る上下2つの取付座6a,6aが形成されている。 FIG. 2 (a) is an exploded perspective view showing a pair of left and right support arms 1 and 1, two left and right handrail receivers 1a and 1a, and two left and right seat plates 1b and 1b. Two upper and lower mounting seats 6 a and 6 a that can be interposed between the two support arms 1 and 1 are formed on the upper cover 6 of the covers 6 and 6.
