Description

【０００１】
【発明の属する技術分野】
この発明は、裏面側に手が入らないような条件の壁等に、各種部材をボルト、ナットで取り付けるために用いるための壁等への部材取り付け金具に関する。
【０００２】
【従来の技術】
裏面に手が入らないような条件の壁、例えば、ユニットバス等の壁に握りバー等を後付けにより取り付けるには、壁の前面側からの操作だけで取り付け作業を行わなければならないという制約がある。
【０００３】
従来、上記のような制約のある部分での部材の取り付けに用いられている部材取り付け装置は、図１０と図１１に示すように、長方形となる四枚の羽根板１と、この羽根板１を取り付けるボルト２と、ボルト２に挿通する部材結合具３と、ボルト２に螺合して羽根板１と部材結合具３を締結するナット４とからなり、上記四枚の羽根板１は、折り曲げ段部を設けた一方端部をボルト２に取り付け、一番奥の羽根板１をボルト２の頭部端に固定すると共に、残りの羽根板１をボルト２に対して回転自在とし、ボルト２に挿通した部材結合具３に、握りバー５の接続ナット６を螺合する雄ねじ軸部７を設けた構造になっている。
【０００４】
上記部材取り付け装置を用いて、壁Ａに握りバー５を後付けにより取り付けるには、壁Ａに羽根板１の幅が通過できる程度の直径を有する取り付け孔Ｂを穿設し、壁Ａの前面側から同じ位相に重ね合わせた羽根板１を先端側から挿入し、この状態で取り付け孔Ｂから指先を入れて壁Ａの裏面側で四枚の羽根板１を四方に分配し、次に、ボルト２を手前に引き寄せて四枚の羽根板１を壁Ａの裏面側に当接させ、このボルト２に挿通した部材結合具３を壁Ａの前面側に押し当て、部材結合具３の筒状部８を取り付け孔Ｂに嵌め合わせた状態で、ボルト２に螺合したナット４をねじ込み、羽根板１と部材結合具３をその対向面間で壁Ａを挟み込んだ状態で締結する。
【０００５】
この後、部材結合具３の雄ねじ軸部７に握りバー５の接続ナット６を螺合することにより、壁Ａへの握りバー５の取り付けが完了する。
【０００６】
【発明が解決しようとする課題】
ところで、上記した部材取り付け装置は、壁Ａの裏面側で四枚の羽根板１を四方に分配させなければならず、この作業は狭い部分で行わなければならないので、作業に手間がかかり、壁Ａの厚みが厚くなるほど作業が行い難くなる。
【０００７】
また、握りバー５の取り付け強度を確保するには、羽根板１と壁Ａの裏面側の接触面積を大きく取る必要があるが、重ね合わせた羽根板１を壁Ａの裏面側に挿入して四方に分配させるためには、取り付け孔Ｂの直径を小さく設定することはできず、このため、羽根板１と壁Ａの裏面側の接触面積を大きくすることが困難となり、握りバー５の取り付け強度に難点がある。
【０００８】
そこで、この発明の課題は、壁に対する前面側からの部材の取り付け作業が簡単に行え、しかも、取付け孔に対して通過させる裏面補強板の直径を可能な限り大きく設定でき、部材の取り付け強度を確保することができる壁等への部材取り付け金具を提供することにある。
【０００９】
【課題を解決するための手段】
上記のような課題を解決するため、この発明は、円形の取り付け孔を設けた壁等の裏面側に位置させる裏面補強板を、塑性変形可能な金属板を用いて略円板状に形成し、前記裏面補強板の中央部分に前面側に突出するボルトを突設し、この裏面補強板の外径を、中央部分に固定したボルトの軸心を中心とする半径方向の寸法が、いずれの方向の位置においても取り付け孔の直径に納まり、かつ、ボルトの軸心を通る直径方向の寸法が、いずれの方向の位置においても取り付け孔の直径より大径になるよう設定し、この裏面補強板に外周の一か所で開放する半径方向のスリットを設け、この裏面補強板のスリット開放端側の外径をスリットを挟んで一方側を大径部で他方側を小径部に形成した構成を採用したものである。
【００１０】
上記した裏面補強板と、取り付け孔よりも大径に形成され、壁等の表面側に位置させる円形固定板との組み合わせからなり、上記円形固定板の中央にボルトへの挿通孔が設けられているようにしたり、上記裏面補強板のスリットは、外周の開放端からボルトを固定した中央部分を通り、開放端と反対側の外周に近接する位置に達するように設けられ、この裏面補強板のスリットを挟む両側が軸方向に変位している構造とすることができる。
【００１３】
上記裏面補強板は、金属板を用い、中央部にボルトが溶接により同軸心状の配置で突出するよう固定されていると共に、この裏面補強板は、壁に設けた取り付け孔の周縁にスリットの軸方向へ段差になっている部分を嵌め込んで回転させるだけで、壁の裏面側へ進入させることができ、裏面補強板の壁の裏面側への配置が簡単に行えると共に、裏面補強板のスリット開放端側の外径をスリットを挟んで一方側が大径部で他方側が小径部に形成したので、取り付け孔の直径に対して裏面補強板の外径を、取り付け孔の通過可能な範囲でできるだけ大径に設定でき、これによって、壁の裏面側に対する裏面補強板の接触面積を大きく確保することができることになる。
【００１４】
また、裏面補強板の形成に塑性変形可能な金属板を用いることにより、スリットを挟む両側の段差になっている部分の段差幅は、壁の厚みに合わせて手で調整できる。
【００１５】
上記円形固定板は、強度のある金属板を用い、取り付け孔の前面側に嵌まる嵌合部の外周に、壁等の前面側に重なる鍔を段付き状に周設し、裏面補強板を壁等の背面側に位置させた状態で、壁等の前面側に突出するボルトにこの円形固定板の挿通孔を挿入し、ボルトに螺合したナットを締め付ければ、裏面補強板と円形固定板で壁等を挟むことにより、壁等の前面側にボルトを突出状に固定配置することができ、このボルトを利用して手摺り等の各種部材を取り付けることができる。
【００１６】
【発明の実施の形態】
以下、この発明の実施の形態を図１乃至図９に示す図示例と共に説明する。
【００１７】
図１乃至図７に示す第１の実施の形態において、壁等への部材取り付け金具１１は、壁Ａに設けた取り付け孔Ｂを通過させて、壁Ａの裏面側に位置させる裏面補強板１２と、この裏面補強板１２の中央位置に前面側へ突出するよう固定したボルト１３とで形成されている。
【００１８】
この部材取り付け金具１１を用いて壁Ａの表面側に固定する取付け部材は、図示の場合、握りバーを壁Ａの表面に配置するためのヒンジブラケット１４を示し、ボルト１３に挿通して壁Ａの外面に重ねるベース部材１５と、ボルト１３に挿通した状態でベース部材１５に外嵌するブラケット本体１６と、ボルト１３への螺締によりベース部材１５とブラケット本体１６を壁Ａに固定するナット１７と、ナット１７の締結部分を覆うようブラケット本体１６に取り付けるカバー部材１８とで形成されている。
【００１９】
上記部材取り付け金具１１の裏面補強板１２は、塑性変形可能な金属プレートを用い、取り付け孔Ｂよりも大径の略円板に形成され、この裏面補強板１２には、中央にボルト１３の挿通用切り欠き１９と、外周の一箇所の開放端からボルト１３を固定する切り欠き１９を通り、開放端と反対側の外周に近接する位置に達する径方向のスリット２０が設けられている。
【００２０】
この裏面補強板１２に対するボルト１３の固定は、切り欠き１９に挿通したボルト１３の頭部１３ａが、裏面補強板１２の背面でスリット２０を境とする一方側の位置に、座金１３ｂを介して溶接されている。
【００２１】
上記裏面補強板１２の外径は、壁Ａに設けた円形の取り付け孔Ｂよりも大径の略円板状とすると共に、この裏面補強板１２の外径は、中央部分に固定したボルト１３の軸心を中心とする半径方向の寸法が、いずれの方向の位置においても取り付け孔Ｂの直径に納まり、かつ、ボルト１３の軸心を通る直径方向の寸法が、いずれの方向の位置においても取り付け孔Ｂの直径よりも大径になるよう設定されている。
【００２２】
また、裏面補強板１２は、上記スリット２０を挟む両側の部分が、軸方向に変位させることにより段差になっている。裏面補強板１２の形成に塑性変形可能な金属板を用いることにより、スリット２０を挟む両側の段差になっている部分の段差幅は、壁Ａの厚みに合わせて現場で手によって調整できることになる。
【００２３】
この裏面補強板１２は、壁Ａに設けた取り付け孔Ｂの周縁にスリット２０の軸方向へ段差になっている部分を開放端から嵌め込んで、ボルト１３を中心に回転させるだけで、壁Ａの裏面側へ進入させることができ、裏面補強板１２の壁Ａに対する裏面側への配置が簡単に行えることになる。
【００２４】
この裏面補強板１２は、上記のような外径の条件において、裏面補強板１２のスリット２０の開放端側の外径をスリット２０を挟んで一方側が大径部１２ａで他方側が小径部１２ｂに形成されている。
【００２５】
図７に示す裏面補強板１２は、スリット２０の一方側縁をこの裏面補強板１２の軸心を通る中心線に対して合わせ、スリット２０の配置を裏面補強板１２の軸心に対して片寄って設け、ボルトを裏面補強板１２の軸心と同軸に取り付けるようにした例を示している。
【００２６】
ここで、壁Ａに設ける取り付け孔Ｂの直径を、例えば５０ｍｍとした場合、裏面補強板１２は、スリット２０の開放端側の外径で小径部１２ｂ側の半径を３５ｍｍとして、残りの部分の外径の半径を４０ｍｍとすることにより、実質的に裏面補強板１２の直径を略８０ｍｍに設定することができ、取り付け孔Ｂの直径に比べてはるかに大きな直径の裏面補強板１２を、取り付け孔Ｂに対して通過させることで、壁Ａの裏面側に配置することができ、壁Ａの裏面側に対して裏面補強板１２は大きな接触面積を確保することができる。
【００２７】
図１における符号２１は、壁Ａの裏面側に部材取り付け金具１１が落ち込まないようにするための係止金具を示し、壁Ａに設けた取り付け孔Ｂの直径よりも長い金属製帯板２２に先端で開放すると共に内端に向けて狭くなる溝２３を設け、この金属製帯板２２の後端に屈曲部２４を折り曲げてＬ字状に形成され、溝２３をボルト１３に直交するよう差し込み、溝２３の側縁をボルト１３の雄ねじに係合させるようになっている。
【００２８】
図８と図９に示す第２の実施の形態は、壁Ａの取り付け孔Ｂよりも大径に形成され、壁Ａの表面側に位置させる円形固定板３１を組み合わせ使用する例を示している。なお、第１の実施の形態と同一部分は同一符号を付して説明に代える。
【００２９】
この円形固定板３１は、強度のある金属板を用い、取り付け孔Ｂの前面側に嵌まる嵌合部３２の中心部にボルト１３の挿通孔３３が設けられ、嵌合部３２の外周に、壁Ａの前面側に重なる鍔３４を段付き状に周設した構造を有し、嵌合部３２の外周に鍔３４をプレス成形することにより、強度の向上が図られている。
【００３０】
上記円形固定板３１は、裏面補強板１２を壁Ａの背面側に位置させた状態で、壁Ａの前面側に突出するボルト１３に、この円形固定板３１の挿通孔３３を挿入し、ボルト１３に螺合したナット３５を締め付ければ、裏面補強板１２と円形固定板３１で壁Ａを挟むことにより、壁Ａの前面側にボルト１３を突出状に固定配置することができ、このボルト１３を利用して握りバー等の各種部材を取り付けることができる。
【００３１】
また、円形固定板３１の取り付けにより、この円形固定板３１で取り付け孔Ｂを閉鎖するこことができ、壁Ａの内側から外側への水の流出を防止することができるという効果がある。
【００３２】
この発明の部材取り付け金具１１は、上記のような構成であり、次に、この部材取り付け金具１１を用いてユニットバス等の壁Ａに握りバーを後付けにより取り付ける方法を説明する。
【００３３】
先ず、壁Ａには予め壁Ａの握りバーを取り付ける位置に取り付け孔Ｂを穿設しておく。
【００３４】
部材取り付け金具１１のボルト１３を保持し、図４のように、壁Ａに設けた取り付け孔Ｂの周縁に裏面補強板１２のスリット２０の段差になっている部分を開放端から嵌め込み、この裏面補強板１２を壁Ａの裏面側に位置する外径が小径部１２ｂとなる部分が壁Ａの裏面側に進入する方向に回転させることにより、壁Ａの裏面側に裏面補強板１２を配置する。
【００３５】
図４乃至図６は、裏面補強板１１を壁Ａの裏面側に配置する工程を壁Ａの裏面側から見た状態で順番に示しており、図４は、取り付け孔Ｂの周縁に裏面補強板１２のスリット２０の段差になっている部分を開放端から嵌め込んだ初期の状態を示し、裏面補強板１２のスリット２０を挟んで外径が小径部１２ｂとなる部分が壁Ａの裏面側に進入している。
【００３６】
この状態から同図の矢印のように、ボルト１３で軸心を中心にして裏面補強板１２を回転させると、スリット２０が壁Ａの周縁に進入することで、図５のように、丁度ねじが進入していくように、裏面補強板１２の壁Ａの裏面側に進入する部分が増大し、さらに裏面補強板１２を回転させることで、図６のように、裏面補強板１２の全体が壁Ａの裏面側に進入することになる。
【００３７】
このように、裏面補強板１２に直径方向のスリット２０を設けることにより、取り付け孔Ｂに対して二倍弱の外径を有する裏面補強板１２を、取り付け孔Ｂから壁Ａの裏面側に進入させることができ、裏面補強板１２は略円板であり、かつ、取り付け孔Ｂに対して直径の差が十分にあるので、裏面補強板１２と壁Ａの裏面側の接触面積を広く確保できることになる。
【００３８】
上記裏面補強板１２が壁Ａの裏面側に位置すると、ボルト１３を手前側に引いて裏面補強板１２を壁Ａの裏面側に当接させ、取り付け孔Ｂの中央にボルト１３を位置させた状態で、壁Ａの前面側に重ねた係止金具２１をスライドさせ、図１と図６のように、その二又部の溝２３をボルト１３のねじ山に係止すると、部材取り付け金具１１は手を放しても壁Ａに対して裏面側に落ち込まないように仮止め保持され、壁Ａの前面側にボルト１３が突出した状態となる。
【００３９】
次に、図２と図３に示す第１の実施の形態では、壁Ａの前面側へ取り付け孔Ｂから突出するボルト１３に、ベース部材１５とブラケット本体１６を挿通し、ブラケット本体１６から突出するボルト１３にナット１７を螺合し、この時点で係止金具２１をボルト１３から抜き取り、ブラケット本体１６に握りバーを嵌合した状態でナット１７の締め付けを行い、ベース部材１５とブラケット本体１６を壁Ａの前面に固定し、ブラケット本体１６にカバー部材１８を取り付けることで、ユニットバス等の壁Ａに握りバーを取り付けることができる。なお、壁Ａとベース部材１５の重なり面間には、防水用のパッキング２５を介在させている。
【００４０】
このような握りバーの固定において、裏面補強板１２が壁Ａの裏面側で取り付け孔Ｂの周囲に重なることで、裏面側に手が入らないような条件においても、取り付け孔Ｂより大径の裏面補強板１２を配置させることができ、従って、耐引き抜き強度の優れた固定状態が得られることになる。
【００４１】
また、図８に示す第２の実施の形態では、壁Ａの前面側へ取り付け孔Ｂから突出するボルト１３に円形固定板３１の挿通孔３３を挿入し、ボルト１３に螺合したナット３５を締め付ければ、裏面補強板１２と円形固定板３１で壁Ａを挟むことにより、壁Ａの前面側にボルト１３を突出状に固定配置することができる。
【００４２】
この後、ボルト１３にベースブロック３６とこれに外嵌する取り付けブラケット３７を挿入し、ボルト１３に螺合したナット３８を締め付けてこれらを壁Ａの前面側に固定し、取り付けブラケット３７に握りバー３９の端部を外嵌固定すれば、壁Ａに握りバー３９を取り付けることができる。
【００４３】
このように、円形固定板３１を組み合わせ使用すると、裏面補強板１２と円形固定板３１で壁Ａを挟むことにより、ボルト１３を壁Ａに対して単独で固定することができ、ボルト１３への握りバー３９の固定作業が効率よく行えることになる。
【００４４】
【発明の効果】
以上のように、この発明によると、裏面補強板のスリットを壁に設けた取り付け孔の周囲に挿入した状態で、この裏面補強板を回転させるだけで、壁の裏面側に裏面補強板を配置するようにした部材取り付け金具において、裏面補強板の外径を取り付け孔よりも大径とすると共に、この裏面補強板のスリット開放端側の外径をスリットを挟んで一方側を大径部で他方側が小径部に形成したので、壁に設けた取り付け孔の直径に対して裏面補強板を通過可能な範囲でできるだけ大径に形成することができ、これにより、裏面補強板と壁の裏面側の接触面積を広く確保でき、耐引き抜き強度の向上を図ることができる。
【００４５】
また、裏面補強板のスリットを、外周の開放端からボルトを固定した中央部分を通り、開放端と反対側の外周に近接する位置に達するように設けたので、スリットが長くなることで、裏面補強板のスリットを挟む両側部分の段差幅の調整範囲が拡大し、異なる壁の厚みに広範に対応することができることになる。
【００４６】
さらに、ボルトに挿入する円形固定板を組み合わせ使用することにより、壁へボルトを先に固定した状態で、ボルトに対する握りバー等の固定が行えることになり、握りバー等の固定作業が能率的に実施できる。

BACKGROUND OF THE INVENTION
The present invention relates to a member mounting bracket to a wall or the like for use in attaching various members to a wall or the like that does not allow a hand on the back side with bolts and nuts.
[0002]
[Prior art]
In order to attach a grip bar or the like to a wall such as a unit bath that cannot be reached on the back surface, such as a unit bath by retrofitting, there is a restriction that the installation work must be performed only from the front side of the wall. .
[0003]
Conventionally, as shown in FIGS. 10 and 11, a member mounting apparatus used for mounting a member at a portion having the above-described restriction includes four blade plates 1 having a rectangular shape, and the blade plates 1. A bolt 2, a member coupler 3 inserted through the bolt 2, and a nut 4 screwed into the bolt 2 to fasten the blade plate 1 and the member coupler 3, and the four blade plates 1 are One end provided with a folding step is attached to the bolt 2, the innermost blade 1 is fixed to the head end of the bolt 2, and the remaining blade 1 is rotatable with respect to the bolt 2. 2 is provided with a male screw shaft portion 7 into which the connection nut 6 of the grip bar 5 is screwed.
[0004]
In order to attach the grip bar 5 to the wall A by retrofitting using the above-described member attaching device, an attachment hole B having a diameter that allows the width of the blade 1 to pass through is drilled in the wall A, and the front side of the wall A The blades 1 superimposed on the same phase are inserted from the tip side, and in this state, the fingertips are inserted from the mounting holes B, and the four blades 1 are distributed in four directions on the back side of the wall A. 2 is pulled forward, the four blades 1 are brought into contact with the back side of the wall A, the member coupler 3 inserted through the bolt 2 is pressed against the front side of the wall A, and the cylindrical shape of the member coupler 3 In a state where the portion 8 is fitted in the mounting hole B, the nut 4 screwed into the bolt 2 is screwed, and the blade plate 1 and the member coupler 3 are fastened with the wall A sandwiched between the opposing surfaces.
[0005]
Thereafter, the connection nut 6 of the grip bar 5 is screwed onto the male screw shaft portion 7 of the member coupler 3, whereby the attachment of the grip bar 5 to the wall A is completed.
[0006]
[Problems to be solved by the invention]
By the way, the above-described member mounting apparatus has to distribute the four blades 1 in four directions on the back surface side of the wall A, and this operation must be performed in a narrow portion, so that the operation takes time and the wall The thicker the thickness of A, the harder it is to work.
[0007]
Moreover, in order to ensure the attachment strength of the grip bar 5, it is necessary to increase the contact area between the blade plate 1 and the back surface side of the wall A, but the overlapped blade plate 1 is inserted into the back surface side of the wall A. In order to distribute in all directions, the diameter of the mounting hole B cannot be set small. For this reason, it is difficult to increase the contact area between the blade plate 1 and the back side of the wall A, and the grip bar 5 is attached. There are difficulties in strength.
[0008]
Therefore, the problem of the present invention is that the work of attaching the member from the front side to the wall can be performed easily, and the diameter of the back reinforcing plate to be passed through the attachment hole can be set as large as possible, and the attachment strength of the member The object is to provide a member mounting bracket to a wall or the like that can be secured.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention forms a back reinforcing plate positioned on the back side of a wall or the like provided with a circular mounting hole in a substantially disc shape using a plastically deformable metal plate. , A bolt projecting to the front side is provided at the center portion of the back reinforcing plate, and the outer diameter of the back reinforcing plate is the radial dimension around the axis of the bolt fixed to the center portion. This back reinforcing plate is set so that it fits in the diameter of the mounting hole at the position in the direction and the diameter dimension passing through the axis of the bolt is larger than the diameter of the mounting hole in the position in any direction. A slit in the radial direction that opens at one place on the outer periphery is provided, and the outer diameter on the slit open end side of this back reinforcing plate is formed with one side being a large diameter part and the other side being a small diameter part across the slit. Adopted.
[0010]
It consists of a combination of the above-mentioned back reinforcing plate and a circular fixing plate that has a larger diameter than the mounting hole and is positioned on the front side of the wall, etc., and an insertion hole for a bolt is provided in the center of the circular fixing plate. The slit of the back reinforcing plate is provided so as to reach a position close to the outer periphery on the side opposite to the open end through the central portion where the bolt is fixed from the open end of the outer periphery. A structure in which both sides sandwiching the slit are displaced in the axial direction can be employed.
[0013]
The back reinforcing plate uses a metal plate, and is fixed so that a bolt protrudes in a coaxially central arrangement by welding at the center, and this back reinforcing plate has a slit on the periphery of the mounting hole provided in the wall. Just by inserting and rotating the stepped part in the axial direction, it is possible to enter the back side of the wall, and it is easy to arrange the back side reinforcing plate on the back side of the wall, and the back side reinforcing plate Since the outer diameter on the slit open end side is formed with a large diameter part on one side and a small diameter part on the other side across the slit, the outer diameter of the back reinforcing plate can be set within the range in which the mounting hole can pass with respect to the diameter of the mounting hole. The diameter can be set as large as possible, and as a result, a large contact area of the back reinforcing plate to the back side of the wall can be secured.
[0014]
In addition, by using a plastically deformable metal plate for forming the back reinforcing plate, the step width of the step portions on both sides sandwiching the slit can be adjusted by hand according to the thickness of the wall.
[0015]
The circular fixing plate is a strong metal plate, and has a stepped ridge around the front side of the wall or the like on the outer periphery of the fitting portion that fits on the front side of the mounting hole. Insert the insertion hole of this circular fixing plate into the bolt that protrudes to the front side of the wall, etc. while being positioned on the back side of the wall, etc., and tighten the nut screwed to the bolt to fix the back reinforcing plate to the circular shape. By sandwiching a wall or the like with a plate, a bolt can be fixedly arranged on the front side of the wall or the like, and various members such as a handrail can be attached using this bolt.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below together with examples shown in FIGS.
[0017]
In the first embodiment shown in FIG. 1 to FIG. 7, the member mounting bracket 11 to the wall or the like passes through the mounting hole B provided in the wall A and is positioned on the back side of the wall A. And a bolt 13 fixed so as to protrude to the front side at the center position of the back reinforcing plate 12.
[0018]
The attachment member fixed to the surface side of the wall A by using this member attachment metal fitting 11 shows a hinge bracket 14 for arranging the grip bar on the surface of the wall A in the case of illustration, and is inserted into the bolt 13 and inserted into the wall A. A base member 15 that overlaps the outer surface of the base member 15, a bracket main body 16 that is externally fitted to the base member 15 while being inserted into the bolt 13, and a nut 17 that fixes the base member 15 and the bracket main body 16 to the wall A by screwing to the bolt 13. And a cover member 18 attached to the bracket body 16 so as to cover the fastening portion of the nut 17.
[0019]
The back reinforcing plate 12 of the member mounting bracket 11 is formed of a plastically deformable metal plate and is formed into a substantially circular plate having a diameter larger than the mounting hole B. The back reinforcing plate 12 has a bolt 13 inserted in the center. A radial slit 20 is provided that passes through a notch 19 that is commonly used and a notch 19 that fixes the bolt 13 from one open end of the outer periphery and reaches a position close to the outer periphery on the side opposite to the open end.
[0020]
The bolt 13 is fixed to the back surface reinforcing plate 12 with the head portion 13a of the bolt 13 inserted through the notch 19 at a position on one side of the back surface of the back surface reinforcing plate 12 with the slit 20 as a boundary via a washer 13b. Welded.
[0021]
The outer diameter of the back reinforcing plate 12 is a substantially disc shape having a larger diameter than the circular mounting hole B provided in the wall A, and the outer diameter of the back reinforcing plate 12 is a bolt 13 fixed to the center portion. The dimension in the radial direction centered on the shaft center of the bolt 13 is accommodated in the diameter of the mounting hole B in any position, and the dimension in the diameter direction passing through the shaft center of the bolt 13 is in any position. The diameter is set to be larger than the diameter of the mounting hole B.
[0022]
Further, the back reinforcing plate 12 is stepped by displacing both side portions sandwiching the slit 20 in the axial direction. By using a metal plate that can be plastically deformed for forming the back reinforcing plate 12, the step width of the stepped portions on both sides sandwiching the slit 20 can be adjusted by hand in the field according to the thickness of the wall A. .

The back reinforcing plate 12 is formed by inserting a portion that is stepped in the axial direction of the slit 20 into the peripheral edge of the mounting hole B provided in the wall A from the open end, and rotating it around the bolt 13. Thus, the rear surface reinforcing plate 12 can be easily arranged on the rear surface side with respect to the wall A.
[0024]
Under the condition of the outer diameter as described above, the rear reinforcing plate 12 has an outer diameter on the open end side of the slit 20 of the rear reinforcing plate 12 with the slit 20 sandwiching the outer diameter on one side and a smaller diameter portion 12b on the other side. Is formed.
[0025]
The back reinforcing plate 12 shown in FIG. 7 has one side edge of the slit 20 aligned with the center line passing through the axis of the back reinforcing plate 12, and the arrangement of the slit 20 is offset with respect to the axis of the back reinforcing plate 12. In this example, the bolts are mounted coaxially with the axis of the back reinforcing plate 12.
[0026]
Here, when the diameter of the mounting hole B provided in the wall A is 50 mm, for example, the back reinforcing plate 12 has an outer diameter on the open end side of the slit 20 and a radius on the small-diameter portion 12b side of 35 mm. By setting the radius of the outer diameter to 40 mm, the diameter of the back reinforcing plate 12 can be substantially set to about 80 mm, and the back reinforcing plate 12 having a diameter much larger than the diameter of the mounting hole B is attached. By passing through the hole B, it can be arranged on the back side of the wall A, and the back reinforcing plate 12 can secure a large contact area with respect to the back side of the wall A.
[0027]
Reference numeral 21 in FIG. 1 denotes a locking bracket for preventing the member mounting bracket 11 from dropping on the back side of the wall A, and a metal strip 22 longer than the diameter of the mounting hole B provided in the wall A. A groove 23 that opens at the front end and narrows toward the inner end is provided, and a bent portion 24 is bent at the rear end of the metal strip 22 to form an L shape. The groove 23 is inserted so as to be orthogonal to the bolt 13. The side edge of the groove 23 is engaged with the male screw of the bolt 13.
[0028]
The second embodiment shown in FIGS. 8 and 9 shows an example in which a circular fixing plate 31 that is formed to have a diameter larger than the mounting hole B of the wall A and is positioned on the surface side of the wall A is used in combination. . Note that the same parts as those of the first embodiment are denoted by the same reference numerals and are not described.
[0029]
The circular fixing plate 31 is a strong metal plate, and an insertion hole 33 for the bolt 13 is provided at the center of the fitting portion 32 that fits on the front side of the mounting hole B. Strength is improved by having a structure in which a flange 34 that overlaps the front side of the wall A is provided in a stepped manner, and the flange 34 is press-molded on the outer periphery of the fitting portion 32.
[0030]
The circular fixing plate 31 is formed by inserting the insertion holes 33 of the circular fixing plate 31 into the bolts 13 projecting to the front side of the wall A with the back reinforcing plate 12 positioned on the back side of the wall A. By tightening the nut 35 screwed onto the wall 13, the wall A is sandwiched between the back reinforcing plate 12 and the circular fixing plate 31, so that the bolt 13 can be fixedly arranged in a protruding manner on the front side of the wall A. 13 can be used to attach various members such as a grip bar.
[0031]
Moreover, the attachment of the circular fixing plate 31 enables the attachment hole B to be closed by the circular fixing plate 31, and there is an effect that the outflow of water from the inside to the outside of the wall A can be prevented.
[0032]
The member mounting bracket 11 of the present invention is configured as described above. Next, a method for attaching a grip bar to the wall A of a unit bus or the like by using the member mounting bracket 11 will be described.
[0033]
First, a mounting hole B is formed in the wall A in advance at a position where the grip bar of the wall A is attached.
[0034]
The bolt 13 of the member mounting bracket 11 is held, and as shown in FIG. 4, a portion that is a step of the slit 20 of the back reinforcing plate 12 is fitted from the open end to the periphery of the mounting hole B provided in the wall A. The back reinforcing plate 12 is arranged on the back side of the wall A by rotating the reinforcing plate 12 in a direction in which the portion where the outer diameter is the small diameter portion 12b located on the back side of the wall A enters the back side of the wall A. .
[0035]
4 to 6 sequentially show the steps of arranging the back reinforcing plate 11 on the back side of the wall A as viewed from the back side of the wall A. FIG. An initial state in which the stepped portion of the slit 20 of the plate 12 is fitted from the open end is shown, and the portion where the outer diameter becomes the small diameter portion 12b across the slit 20 of the back reinforcing plate 12 is the back side of the wall A Has entered.
[0036]
From this state, when the back reinforcing plate 12 is rotated around the shaft center with the bolt 13 as shown by the arrow in the figure, the slit 20 enters the peripheral edge of the wall A, and as shown in FIG. The portion of the back reinforcing plate 12 that enters the back side of the wall A increases, and the back reinforcing plate 12 is further rotated so that the entire back reinforcing plate 12 is It will enter the back side of wall A.
[0037]
Thus, by providing the slit 20 in the diametrical direction on the back surface reinforcing plate 12, the back surface reinforcing plate 12 having an outer diameter slightly less than twice the mounting hole B enters the back surface side of the wall A from the mounting hole B. Since the back reinforcing plate 12 is a substantially circular plate and has a sufficient difference in diameter with respect to the mounting hole B, a wide contact area between the back reinforcing plate 12 and the back side of the wall A can be secured. become.
[0038]
When the back reinforcing plate 12 is positioned on the back side of the wall A, the bolt 13 is pulled toward the near side to bring the back reinforcing plate 12 into contact with the back side of the wall A, and the bolt 13 is positioned in the center of the mounting hole B. In this state, when the latching bracket 21 overlapped on the front side of the wall A is slid and the groove 23 of the bifurcated portion is latched to the thread of the bolt 13 as shown in FIGS. Is temporarily fixed so that it does not fall to the back side with respect to the wall A even if the hand is released, and the bolt 13 protrudes from the front side of the wall A.
[0039]
Next, in the first embodiment shown in FIGS. 2 and 3, the base member 15 and the bracket body 16 are inserted into the bolt 13 protruding from the mounting hole B to the front surface side of the wall A and protrude from the bracket body 16. The nut 17 is screwed onto the bolt 13 to be removed, and at this point, the locking member 21 is removed from the bolt 13, and the nut 17 is tightened in a state where the grip bar is fitted to the bracket main body 16. Is fixed to the front surface of the wall A, and the cover member 18 is attached to the bracket body 16, whereby the grip bar can be attached to the wall A of the unit bus or the like. A waterproof packing 25 is interposed between the overlapping surfaces of the wall A and the base member 15.
[0040]
In fixing such a grip bar, the back reinforcing plate 12 overlaps with the periphery of the mounting hole B on the back side of the wall A, so that the diameter is larger than that of the mounting hole B even under conditions where the hand does not enter the back side. The back reinforcing plate 12 can be disposed, and thus a fixed state with excellent pull-out strength can be obtained.
[0041]
In the second embodiment shown in FIG. 8, the insertion hole 33 of the circular fixing plate 31 is inserted into the bolt 13 protruding from the mounting hole B to the front side of the wall A, and the nut 35 screwed into the bolt 13 is installed. When tightened, the wall 13 is sandwiched between the back reinforcing plate 12 and the circular fixing plate 31 so that the bolt 13 can be fixedly disposed in a protruding manner on the front side of the wall A.
[0042]
Thereafter, the base block 36 and the mounting bracket 37 that is externally fitted to the bolt 13 are inserted into the bolt 13, and the nut 38 that is screwed into the bolt 13 is tightened to fix them to the front side of the wall A. If the end portion of 39 is fitted and fixed, the grip bar 39 can be attached to the wall A.
[0043]
As described above, when the circular fixing plate 31 is used in combination, the bolt 13 can be fixed to the wall A independently by sandwiching the wall A between the back reinforcing plate 12 and the circular fixing plate 31. The fixing work of the grip bar 39 can be performed efficiently.
[0044]
【The invention's effect】
As described above, according to the present invention, the back reinforcing plate is disposed on the back side of the wall simply by rotating the back reinforcing plate with the slit of the back reinforcing plate inserted around the mounting hole provided in the wall. In the member mounting bracket, the outer diameter of the back reinforcing plate is made larger than the mounting hole, and the outer diameter of the back reinforcing plate on the slit open end side is the large diameter portion on one side with the slit interposed therebetween. Since the other side is formed in a small diameter portion, it can be formed as large as possible within the range that can pass through the back reinforcing plate with respect to the diameter of the mounting hole provided in the wall. A wide contact area can be secured, and the pull-out strength can be improved.
[0045]
In addition, the slit on the back reinforcing plate is provided so that it passes through the central part where the bolt is fixed from the open end of the outer periphery and reaches a position close to the outer periphery on the side opposite to the open end. The adjustment range of the step width of both side portions sandwiching the slit of the reinforcing plate is expanded, and it is possible to widely cope with different wall thicknesses.
[0046]
Furthermore, by using a combination of circular fixing plates to be inserted into the bolts, it is possible to fix the grip bars and the like to the bolts with the bolts fixed to the wall first. Can be implemented.
