【発明の属する技術分野】
この発明は、竪樋又は水平な樋を壁、屋根下面に取付けて固定する樋固定構造に関する。
【０００２】
【従来の技術】
竪樋を建物の壁に沿って固定する樋固定構造（又は取付構造）は、古くは円環状の樋把持具の一対を対向させて樋を挟み、その基部を壁に埋込んで固定する構造が一般的であったが、樋把持具が竪樋の表面に表出し、美観を低下させる、又固定の際に針金による係止作業を必要とする等の理由から、竪樋の表面に樋把持具が表出しない樋固定構造について様々の提案が行われている。
【０００３】
その一例として、特許文献１の「竪樋の取付構造」の考案が知られている。この取付構造は、断面角形の竪樋の一側面に沿ってその中央部に細幅開口部を有する係止溝を形成した竪樋を、釘杆固定孔を有する基杆の端に帯板状の係止片を形成した係止具を竪樋の係止溝に挿入、回動させて係止片を係止し、係止具の釘杆固定孔に釘杆を嵌合させて、壁に固定された釘杆によって壁に取付けするように構成されたものである。
【０００４】
他の例として、特許文献２の「竪どいと控金具との固定構造」の考案が知られている。この考案の固定構造は、断面角筒状の竪樋の一側面に２つの凹所と突条とを形成した竪樋を、コ字形の係合部を先端にそれぞれ有する支持杆と当て金から成る控金具を用い、その係合部を突条に結合させ、かつ支持杆と当て金とを結合させることにより壁面に固定するように構成したものである。

【発明が解決しようとする課題】
上述した２つの特許文献の考案で提案されている取付構造又は固定構造では樋把持具が竪樋の表面に表出することがなく、美観を損ねずに、また針金を用いることなく建物の壁面に固定することができ、かつ構成が簡易である点でそれぞれ優れた構造を提案している。しかし、特許文献１の取付構造では釘杆の端を係止具の基杆の釘杆固定孔に嵌合させて固定しているだけであるから、竪樋の固着が十分でない。特許文献２の固定構造ではコ字形係合部を突条に結合するだけであるから、これも固着としては不十分である。
【０００７】
この発明は、上記の問題に留意して、樋を壁面又は屋根下面に取付ける際に樋表面に取付部材が表出しないようにして美観を保持し、簡単な構成で取付作業が容易であることは勿論、さらに樋の固定状態が安定した固着状態となり得る樋固定構造を提供することを課題とする。
【０００８】
【課題を解決するための手段】
この発明は、上記の課題を解決する手段として、樋の断面一側方に形成した係合凹部と、この係合凹部に係合して樋を壁面に固定する控具とから成り、係合凹部は樋外面から内側に屈曲する入口の両側に係合縁材を有し、控具は壁面に固定される取付座と、この取付座に取付され、係合縁材を取付座との間に挟む押え片を有する係合子とを有し、上記係合縁材間の溝から係合子を挿入、回転させて押え片を係合縁材に当接させ、取付座の取付面との間に挟んで樋を固定するようにした樋固定構造としたのである。
【０００９】
上記の構成としたこの発明の樋固定構造によれば、樋は美観を損なうことなく、簡易な取付具により壁面に安定してしっかりと固着され、作業も容易である。取付座は予め壁面に所定の間隔で必要数だけ取付けられているものとする。樋に対し、取付座に対応する係合子を樋の係合凹部の入口両側の係合縁材間に挿入して係合子を回転させ、係合子の押え片を係合縁材に対向させる。
【００１０】
係合子を係合縁材に対向保持した状態で係合子を樋と共に取付座に接近させて固定手段などにより取付座に取付ける。その際、係合子の押え片は取付座の取付面との間に係合縁材を挟んで取付座に取付けられ、従って係合子を取付座に固着する固着力により樋の係合縁材も固着され、このため樋は取付座を介して壁面にしっかりと固定される。
【００１１】
又、取付座を断面視台形状とし、係合縁材のスカート部が取付座の斜辺頂部に互に密着して接する形状に設けられるようにすると、取付座の斜辺頂部でさらに取付座に対し密着して固定され、樋が取付座に対し、従来のようにわずかな隙間が残存していることにより不安定な固着となることがなくなる。
【００１２】
【実施の形態】
以下、この発明の実施の形態について図面を参照して説明する。図１は実施形態の樋固定構造の主横断面図である。図示のように、樋固定構造Ａは、竪樋１の一側方に係合凹部２を竪樋１の長手方向に形成し、この係合凹部２に係合して竪樋１を建物の壁面Ｗに固定するための控具とを備えている。係合凹部２は、樋外面から内側に屈曲する入口の両側に係合縁材３ａ、３ｂを有し、この係合縁材３ａ、３ｂのスカート部３ｃ、３ｃはやや傾斜して設けられている。係合縁材３ａと３ｂの対向する面間の溝３ｓは、係合凹部２の開口を形成している。
【００１３】
控具は、壁面に固定される取付座５と、この取付座５にねじ係合により取付けされ、係合縁材３ａ、３ｂを取付座５との間に挟む押え片４ａ、４ｂを有する係合子４とを有する。押え片４ａ、４ｂは断面コ字状で、取付座５の取付面５ａとの間に係合縁材３ａ、３ｂを挟む際に、先端のスカート部端が係合縁材３ａ、３ｂの係合凹部２との接続辺に当接しない厚さに形成され、かつ係合凹部２の内面と押え片４ａ、４ｂの対向面との間の隙間より短くスカート部端の厚さは設定されている。
【００１４】
さらに取付座５は、断面視台形状に形成され、その斜辺頂部コーナに上記スカート部３ｃの外面が互いに密着して接するように斜辺の傾斜が設定され、その脚部５ｂは固定ねじ７により建物の壁Ｗに固定される。取付座５に対し係合子４はボルト６ｂ、ナット６ａによる固定手段で固定される。図２に上記係合子４と取付座５の分解斜視図を示す。なお、上記樋固定構造Ａは、図３に示すように、実際の竪樋１の長手方向（上下方向）に沿って図３に示すように、Ａ１ 、Ａ２ 、Ａ３ を所定の間隔で壁Ｗに対し固定する。
【００１５】
上記のように構成した実施形態の樋固定構造Ａは次のように組立てられる。図４の（ａ）図に示すように、竪樋１を壁Ｗに取付ける場合、予め壁Ｗには図３に示す所定間隔に取付座５を取付けておく。取付座５にはボルト６ｂが挿通され、その一端にはナット６ａが嵌合され、他端には係合子４が挿通されている。そして、この係合子４を縦向きにして、固定しようとする竪樋１の係合凹部２の入口の係合縁材３ａ、３ｂ間に形成されている溝３ｓ内に挿入する。
【００１６】
係合子４を溝３ａ内に挿入した後、図４の（ｄ）図に示すように、この係合子４を９０°回転させると、図４の（ｂ）図に示すように、係合子４の押え片４ａ、４ｂが係合縁材３ａ、３ｂに対向して保持される。この状態からボルト６ｂに螺合しているナット６ａを回転させてボルト６ｂによる締結を始める。図４の（ｃ）図に示すように、ナット６ａが回転するにつれてボルト６ｂは係合子４を取付座５へと引き寄せ、同時に竪樋１も取付座５の方へ引き寄せられ、ナット６ａによる締結がボルト基部まで進むと押え片４ａ、４ｂにより係合縁材３ａ、３ｂを取付座５に固着し、図１のような組立完成状態となる。
【００１７】
なお、係合子４の竪樋１への挿入、及び取付座５へのボルト６ｂ、ナット６ａによる締付けは、取付座５の上、下いずれかの方向から手指あるいは工具を差入れて簡単に作業することができる。又、上記実施形態では竪樋１を垂直な壁Ｗに対し取付ける場合について説明したが、この発明の樋固定構造は竪樋１に限らず、図５に示すように、横向きの樋１’に対しても適用できることは詳細に説明するまでもない。さらに、樋の断面形状は円形中空断面のものを示しているが、樋断面形状は角形でもよいことは勿論である。
【００１８】
【発明の効果】
以上、詳細に説明したように、この発明の樋固定構造は樋の一側方に形成した係合凹部の入口両側の係合縁材を取付座の取付面と係合子の押え片との間に挟んで、係合子を取付座に固着する力で同時に押え片により係合縁材を固着するようにしたから、樋の取付部材により美観を損ねることもなく、簡易な構成の部材で樋を取付座を介して壁面にしっかりと安定して固着できるという優れた効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a gutter fixing structure for attaching a gutter or a horizontal gutter to a wall or a lower surface of a roof and fixing it.
[0002]
[Prior art]
The anchor fixing structure (or mounting structure) for fixing the anchor along the wall of the building is a structure in which a pair of circular anchor holders are opposed to each other and the anchor is embedded in the wall and fixed. However, because the heel gripping tool is exposed on the surface of the heel, the aesthetics are deteriorated, and a locking operation with a wire is required for fixing, etc. Various proposals have been made on the heel fixing structure in which the gripper does not appear.
[0003]
As an example thereof, the idea of the “mounting structure of the hook” of Patent Document 1 is known. In this mounting structure, a hook formed with a locking groove having a narrow opening at the center along one side face of a hook having a square cross section is formed as a band plate at the end of a base hook having a nail rod fixing hole. The locking tool formed with the locking piece is inserted into the locking groove of the hook and rotated to lock the locking piece, and the nail hook is fitted into the nail hook fixing hole of the locking tool to It is configured to be attached to the wall by a nail clamp fixed to the wall.
[0004]
As another example, the idea of the “fixing structure between the saddle and the metal fitting” of Patent Document 2 is known. The fixing structure of the present invention is made up of a hook having two recesses and a ridge formed on one side of a hook having a square cross-section, and a support hook and a latch each having a U-shaped engaging portion at the tip. The engaging member is configured to be fixed to the wall surface by coupling the engaging portion to the ridge and by coupling the support rod and the stopper.
