Description

【０００１】
【発明の属する技術分野】
谷形状屋根部の交差線（谷底部）に配設される谷樋において、該谷樋の排水機能を確保するために設ける谷樋カバーに関する。
【０００２】
【従来の技術】
屋根に積もった雪を建屋の周囲に自然落下させることは、建屋に出入する人にとって、いつ屋根から雪が落ちるかわからないといった危惧があるばかりでなく、場所によっては落下した雪が隣地境界線を越えて、近隣に迷惑を与えるという問題がある。
【０００３】
これらの問題に対処するために、積雪地帯でも比較的積雪量が少ない地域では、屋根に積もった雪を屋内暖房の余熱や地下水の熱によって、屋根の上で融雪したり、或いは、屋根の形状を山型でなく谷型として屋根の谷面の交差線に谷樋を配設することで融雪水を建屋内に設置した排水ダクトを通して、地下に流す手段が採用されている。
しかしながら、上記の後者の手段においては、積雪や融雪水の凍結、ゴミ等により、谷樋の排水機能が阻害され、家屋に重大な漏水被害をもたらすことがあり、このために谷樋に排水機能を確保するためのカバーを設けている。
【０００４】
この谷樋カバーには、谷樋上に格子状のスノコあるいは孔のあいたパネル等を単に差渡して載置しただけのものがあるが、このようなものは、風や積もった雪によってはずれることがある。そこで、実公昭６３−４７２２２号公報（図１４参照）にみられるように、カバー本体１１を合成樹脂等の材料とし、谷樋の巾寸法に多少の大小があっても、谷樋カバーの両端を施工時に両手で湾曲して取付枠１２に取り付けるようにしたものがある。
しかし、カバー本体は、積雪荷重に対する材料強度も必要であることから、カバー本体を撓めることができる湾曲可能な材料の利用には限度があり、谷樋の巾寸法に対応した種々の幅のカバー本体を準備する必要が生ずる。
【０００５】
【発明が解決しようとする課題】
本発明は、上記従来技術にかかる谷樋カバーの不具合を解消させることを課題として発明されたものであり、
第１の課題は、軒先への嵌合作業を容易にするとともに、積雪荷重による屋根部の破損を防止することができる谷樋カバーを提供することにある。
【０００６】
第２の課題は、屋根部への取付作業を容易にするとともに、広い範囲の谷樋巾寸法に対応できる谷樋カバーを提供することにある。また、更に、上記課題に加えて、谷樋カバーの流通面・施工面で取扱性の向上をはかった谷樋カバーを提供することにある。

【００１０】
【発明の実施の態様】
以下、本発明の実施例を、図面を参照して説明する。
【実施例１】
実施例１は、図１〜９に示されている。実施例１の谷樋カバーＣは、図１に示すように、全体として長尺の板材からなる山形で両端部に屋根軒先部への装着部を有するものであり、使用態様としては、図７に示すように、屋根Ｒ₁，Ｒ₂の谷部に配設された谷樋Ｕの上部に設置されるものである。上記長尺の板材は、円形の多数の孔１・・・を適宜間隔で穿設した二枚のアルミニウム合金製の押出成形された平板状の板材２，３と、板材２，３のそれぞれの一端縁側を山型にヒンジ機能を持たせた連結部４で連結されている。
【００１１】
（板材２）
一方の板材２は、図３に示すように横長の略長方形状で、図３における上・下端縁が連結部４，６となる。また、板材２の上端縁の全幅には、正面視円筒状で且つ長さ方向に沿ってその一部が切りかかれた湾曲受部２ａが形成され、下端縁は両端部が一定長さに亘って切り欠かれた状態で、断面円形の嵌合軸部２ｂが形成されている。上記湾曲受部２ａの両端部にはネジ溝が形成され、ビス９，９のネジ溝部８，８を構成している。
また、板材２の下面にはその長さ方向に沿って鈎状のバネ受け２ｃが板材２と一体に形成されている。
【００１２】
（板材３）
また、他方の板材３は、図４に示すように、横長の略長方形状で、図４における上・下端縁が連結部４，６となる。また、板材３の上・下端縁には、両端部が一定長さに亘って切り欠かれた状態で、断面円形の嵌合軸部３ｂが形成されている。嵌合軸部３ｂは、正面視円柱状で、湾曲受部２ａ又は後述の軒先嵌合枠５に形成された湾曲受部５ａの内径と略同一の外径を有する。
更に、板材３の下面にはその全長に亘って鈎状のバネ受け３ｃが板材３と一体に形成されている。
【００１３】
（連結部４）
連結部４は、ヒンジ機能を持たせるために、板材２の湾曲受部２ａに、板材３の嵌合軸部３ａが湾曲受部２ａの切欠き部の範囲内で回動可能に嵌合された状態で形成されている。また、嵌合された状態において、ネジ溝部８，８に座金を介してビス９，９が取り付けられる。
【００１４】
（軒先嵌合枠５）
軒先嵌合枠５は、図５に示すように、板材２，３と同一長さで、アルミニウム合金製で押出成形されたもので、正面視略コ字形に形成され、その縦板部に円形の多数の孔１・・・が適宜間隔で穿設され、更に、その肩部に沿って正面視略円形の湾曲受部５ａが形成されている。また、上記湾曲受部５ａの両端部にはネジ溝が形成され（図外）、ネジ溝部を構成している。この軒先嵌合枠５の屋根Ｒ₁，Ｒ₂の軒先当接面には、合成樹脂枠からなる緩衝枠１０が積層されている。
そして、この軒先嵌合枠５は、谷樋カバーＣにおいて、板材２，３の正面視の左右にそれぞれ連結される。
【００１５】
（連結部６）
即ち、板材２，３の縁部の嵌合軸部２ｂと嵌合軸部３ｂが、軒先嵌合枠５の湾曲受部５ａに嵌合され、ヒンジ機能を持って連結部６とされ、嵌合された状態において、座金を介してネジ溝部にビス９，９が取り付けられる。
【００１６】
（弾性金具７）
また、板材２，３が連結部４により連結された状態で、両板材２，３の底面のバネ受け２ｃ，３ｃ間には、倒立Ω形の弾性金具７が弾発状態で装着されており、板材２，３を開き勝手としている。なお、この弾性金具７の形状は、上記倒立Ω形に限定されることなく、弓形、円弧形、くの字形など種々の形状が考えられる。
【００１７】
（屋根Ｒ₁，Ｒ₂間に装着）
谷樋カバーＣは、板材２，３を、図１に示す状態に連結したあと、図９に示すように、ビス９，９・・をネジ溝部に座金等を介してネジ止めして一体物とし、この状態を製品とする。
谷樋カバーＣを現場において屋根Ｒ₁，Ｒ₂の軒先間に装着するには、図６に示すように、谷樋カバーＣの一方の軒先嵌合枠５を屋根Ｒ₁の軒先に嵌合させ、次いで、もう一方の軒先嵌合枠５を、図７に示すように、他方の屋根Ｒ₂の軒先に嵌合させればよい。この軒先への嵌合後において、ビス９，９はネジ溝部８，８にネジ止めしたままでも良いが、取り外してもよい。
図７に示す状態は、谷樋カバーＣを屋根Ｒ₁，Ｒ₂の軒先間に装着した完了状態を示しているが、図８に示すように、軒先嵌合枠５，５が回転して、軒先部に添った姿勢としてもよい。
【００１８】
（実施例１の効果）
実施例１によれば、谷樋カバーＣの軒先への嵌合作業を容易にするとともに、積雪荷重による屋根部の破損を防止することができる。また、谷樋カバーＣをアルミニウム合金等の金属製で構成することで、屋根上の雪を、屋内暖房の余熱や地下水の熱を用いて、効果的に融雪できる。
更に、屋根Ｒ₁，Ｒ₂の軒先間隔の大小に容易に対応させることができ、しかも、谷樋カバーＣの施工時、容易に谷樋カバーＣを開閉（幅の調整）ができるから、作業が容易になり、しかも、軒先嵌合枠５に緩衝枠１０を積層したから屋根Ｒ₁，Ｒ₂の軒先を傷めないという効果もある。
【００１９】
また、実施例１の連結部４，６のネジ溝部８，８には、ビス９，９がネジ止めされているから、板材２の湾曲受部２ａから板材３の嵌合軸部３ａが抜け出ることはなく、また、板材２，３の嵌合軸部２ｂ，３ｂから、軒先嵌合枠５の湾曲受部５ａが分離することもない。したがって、谷樋カバーＣは運搬中に分解することもなく、破損や紛失もなく、施工時の取り扱いも容易である。
【００２０】
【実施例２】
実施例２は、図１０に示されている。この実施例２は、板材２，３と軒先嵌合枠５とを一体物として押出成形したもので、実施例１と比べて連結部６が存在しない点のみが相違する。この実施例２によれば、板材２，３に対する軒先嵌合枠５の回動がないから、屋根の軒先部の傾斜への順応がないものの、実施例１と同様の効果が期待できる外、取付作業は容易であり、広い範囲の谷樋巾寸法に対応させることができる。
【００２１】
【実施例３】
実施例３は、図１１，１２に示されている。実施例１と相違する点は、板材２，３のうち、板材２の幅（図１１では、その長さ）を、板材３より長く形成したものである。作用効果は、実施例１と基本的には同じであるが、実施例３では、積雪状態で板材３側に多く荷重が架かることになることから、屋根Ｒ₁，Ｒ₂側の耐荷重応力との関係で設定すればよい。
【００２２】
【実施例４】
更に、図１３に示すように、連結部４を構成する嵌合軸部２ｂ及び嵌合軸部３ａの少なくとも両端部の断面形状を、中実（実施例１〜３）ではなく、略Ｕ字形（嵌合軸部３ａ内に空間部を形成）とし、内周にネジ溝部８を設けてビス９のネジ止めを可能としたものである。この場合、湾曲受部２ａ，５ａ側には、ネジ溝部８を設ける必要はない。なお、図１３の記載及び上記説明は、板材２の湾曲受部２ａと板材３の嵌合軸部３ａとからなる連結部４の場合を示しているが、連結部６についても同様である。
【００２３】
この実施例４によれば、上記実施例１〜３の谷樋カバーＣが有する効果と同様のものが期待できるばかりでなく、嵌合軸部２ｂ，３ａ側にネジ溝部８を設けてビス止めしたことにより、谷樋カバーＣの切り詰めは、切断のみで組替えの対応が可能となる。換言すれば、板材３の上・下端縁には、実施例１〜３のような両端部が一定長さに亘って切り欠かれた状態にする必要はない。
また、嵌合軸部２ｂ，３ａの端部切り口を湾曲受部２ａ，５ａの端部切り口より、若干突出させて形成した上、ネジ溝部８を設けてビス止めすれば、座金を省略することも可能である。
【００２４】
（他の実施例）
上記各実施例においては、板材２，３の素材をアルミニウム合金製としたが、これに代えて、硬質樹脂製としても同様の効果が得られる。また、連結部４，６を板材２，３の全長に亘って形成したが、構成を簡略化するために連結部は部分的に設けることも可能である。
更に、上記実施例においては、ネジ溝部８は、予めネジ溝を形成しておくものとして説明したが、本発明は、必ずしもこれに限定されるものではなく、ネジ溝部８には、予めネジ溝を設けず、ビスのねじ込みによりネジ溝が形成されるものも含むものである。したがって、本発明の請求項３の構成要件であるビスも、種々のタイプのビス、例えば、タッピングビスなどねじ込みタイプのビスも含むものである。また、ビスに限らず、抜け止め防止機能があれば、他の止め具でもよい。
【００２５】
更に、板材２，３は平坦な板体の他、剛性を向上させるために、全体として湾曲や折曲させてもよく、波板形状としてもよい。
更に、孔１は、円形形状の他、方形状、三角形状等であってもよい。
更に、連結部４は、軒先嵌合枠５，５間に複数個所設けてもよい（実施例１〜４は、連結部４は一箇所のみ）。しかし、この場合には、連結部４，４間に別途板材が必要となる。更に、弾性金具７の代替手段或いは付加的手段として、湾曲受部２ａや嵌合軸部２ｂの素材が持つ弾性（金属弾性又は樹脂弾性）を活用してもよい。
【００２６】
更に、軒先嵌合枠５については、軒先に庇が付設されている場合には、庇にも適用できることは言うまでもない。
なお、上記特許請求の範囲の項には実施例との対応関係を明瞭にするために図面符号を付したが、本発明をこれに限定されるものではない。
【００２７】
【発明の効果】
本発明によれば、上記構成により、下記の効果を奏する。
１．請求項１記載の発明によれば、屋根の谷部に配設された谷樋の上部に設置されるカバーにおいて、孔を適宜間隔で穿設した二つのアルミニウム合金製あるいは硬質樹脂製の板材の一端縁側を山型にヒンジ機能を持たせた連結部で連結するとともに、それぞれの他端縁に略コ状の軒先嵌合枠をヒンジ機能を持たせた連結部により連結し、かつ、両板材の山型内側に弾性金具を装着したことで、谷樋カバーを屋根の軒先の間隔の大小に容易に対応させて幅の調整ができるから、軒先への嵌合作業が容易となる。
また、谷樋カバーをアルミニウム合金等の金属製で構成すれば、屋根上の雪を、屋内暖房の余熱や地下水の熱を用いて効果的に融雪でき、積雪荷重による屋根部の破損を防止することができる。また、軒先嵌合枠に緩衝枠を積層すれば、屋根の軒先を傷めないという効果もある。

【００２９】
３．請求項３記載の発明によれば、請求項１又は請求項２記載の発明の効果に加えて、連結部を構成する二部材の内のいずれかの部材の端部を、二部材の連結状態を保持させるビスのネジ溝部としたことで、谷樋カバーの一体性が損なわれることがない。換言すれば、谷樋カバーＣの輸送中に分解することもなく、破損や紛失もなく、施工時の取り扱いも容易である。

Furthermore, a hook-shaped spring receiver 3 c is formed integrally with the plate 3 on the lower surface of the plate 3 over the entire length thereof.
[0013]
(Connecting part 4)
The connecting portion 4 is fitted to the curved receiving portion 2a of the plate member 2 so that the fitting shaft portion 3a of the plate member 3 can rotate within the range of the cutout portion of the curved receiving portion 2a in order to have a hinge function. It is formed in the state. Further, in the fitted state, screws 9 and 9 are attached to the thread groove portions 8 and 8 through washers.
[0014]
(Eave fitting frame 5)
As shown in FIG. 5, the eaves-end fitting frame 5 has the same length as the plate members 2 and 3 and is made of an aluminum alloy and is formed by extrusion, and is formed in a substantially U-shape when viewed from the front. Are formed at appropriate intervals, and a curved receiving portion 5a having a substantially circular shape in front view is formed along the shoulder portion.

Then, the other eaves edge fitting frame 5 may be fitted to the eaves edge of the other roof R ₂ as shown in FIG. After the fitting to the eaves, the screws 9, 9 may remain screwed to the screw groove portions 8, 8, but may be removed.
The state shown in FIG. 7 shows a completed state in which the valley cover C is mounted between the eaves of the roofs R ₁ and R ₂ , but as shown in FIG. The posture may be in line with the eaves part.
[0018]
(Effect of Example 1)
According to the first embodiment, the fitting operation of the valley cover C to the eaves can be facilitated, and the roof portion can be prevented from being damaged by a snow load. Further, by forming the valley cover C from a metal such as an aluminum alloy, snow on the roof can be melted effectively by using the residual heat of indoor heating or the heat of groundwater.
Furthermore, it is possible to easily cope with the size of the gap between the eaves of the roofs R ₁ and R ₂ , and furthermore, when the valley cover C is constructed, the valley cover C can be easily opened and closed (width adjustment). In addition, since the buffer frame 10 is laminated on the eaves fitting frame 5, the eaves of the roofs R ₁ and R ₂ are not damaged.
[0019]
In addition, since the screws 9 are screwed into the screw groove portions 8 and 8 of the connecting portions 4 and 6 of the first embodiment, the fitting shaft portion 3a of the plate material 3 comes out from the curved receiving portion 2a of the plate material 2. In addition, the curved receiving portion 5a of the eaves-end fitting frame 5 is not separated from the fitting shaft portions 2b, 3b of the plate members 2, 3. Therefore, the valley cover C is not disassembled during transportation, is not damaged or lost, and is easy to handle during construction.
[0020]
[Example 2]
Example 2 is shown in FIG. This Example 2 is obtained by extruding the plate members 2 and 3 and the eaves-end fitting frame 5 as an integral body, and is different from Example 1 only in that the connecting portion 6 does not exist. According to the second embodiment, since there is no rotation of the eaves fitting frame 5 with respect to the plates 2 and 3, there is no adaptation to the inclination of the eaves of the roof, but the same effect as in the first embodiment can be expected, The mounting operation is easy and can correspond to a wide range of valley width dimensions.
[0021]
[Example 3]
Example 3 is shown in FIGS. The difference from Example 1 is that the width of the plate 2 (the length in FIG. 11) of the plates 2 and 3 is longer than that of the plate 3. The operational effect is basically the same as that of the first embodiment, but in the third embodiment, a large load is applied to the plate member 3 side in a snowy state, so that the load bearing stress on the roof R ₁ , R ₂ side is increased. It may be set in relation to.

[Example 4]
Furthermore, as shown in FIG. 13, the cross-sectional shape of at least both ends of the fitting shaft portion 2b and the fitting shaft portion 3a constituting the connecting portion 4 is not substantially solid (Examples 1 to 3), but is substantially U-shaped. (A space portion is formed in the fitting shaft portion 3a), and a screw groove portion 8 is provided on the inner periphery so that the screw 9 can be screwed. In this case, it is not necessary to provide the screw groove portion 8 on the curved receiving portions 2a and 5a side. Although the description of FIG. 13 and the above description show the case of the connecting portion 4 composed of the curved receiving portion 2a of the plate material 2 and the fitting shaft portion 3a of the plate material 3, the same applies to the connecting portion 6.
[0023]
According to the fourth embodiment, not only the same effect as the valley cover C of the first to third embodiments can be expected, but also a screw groove portion 8 is provided on the side of the fitting shaft portions 2b and 3a to fix the screws. As a result, truncation of the trough cover C can be rearranged only by cutting. In other words, it is not necessary for the upper and lower edges of the plate material 3 to be in a state where both ends are cut out over a certain length as in the first to third embodiments.
In addition, the end cuts of the fitting shafts 2b and 3a are formed slightly projecting from the end cuts of the curved receiving parts 2a and 5a, and if the screw groove 8 is provided and screwed, the washer is omitted. Is also possible.

(Other examples)
In each of the above embodiments, the plate materials 2 and 3 are made of an aluminum alloy, but the same effect can be obtained by using a hard resin instead. Moreover, although the connection parts 4 and 6 were formed over the full length of the board | plate materials 2 and 3, in order to simplify a structure, a connection part can also be provided partially.
Furthermore, in the said Example, although the screw groove part 8 demonstrated as what forms a screw groove previously, this invention is not necessarily limited to this, A screw groove is previously contained in the screw groove part 8. The screw groove is formed by screwing in the screw. Therefore, the screw which is the constituent element of claim 3 of the present invention includes various types of screws, for example, screw-type screws such as tapping screws. Further, the stopper is not limited to a screw, and any other stopper may be used as long as it has a retaining function.
[0025]
Further, the plate members 2 and 3 may be curved or bent as a whole or may have a corrugated plate shape in order to improve rigidity in addition to a flat plate body.
Furthermore, the hole 1 may have a square shape, a triangular shape, or the like in addition to the circular shape.
Further, a plurality of connecting portions 4 may be provided between the eaves edge fitting frames 5 and 5 (Examples 1 to 4 have only one connecting portion 4). However, in this case, a separate plate material is required between the connecting portions 4 and 4. Furthermore, the elasticity (metal elasticity or resin elasticity) of the material of the curved receiving portion 2a and the fitting shaft portion 2b may be used as an alternative means or an additional means of the elastic metal fitting 7.
[0026]
Furthermore, it goes without saying that the eaves-end fitting frame 5 can also be applied to eaves when the eaves are provided with eaves.
In addition, although the drawing code | symbol was attached | subjected in order to clarify the correspondence with an Example to the term of the said claim, this invention is not limited to this.

【The invention's effect】
According to the present invention, the above configuration provides the following effects.
1. According to the first aspect of the present invention, in the cover installed at the upper part of the trough disposed in the trough portion of the roof, the two aluminum alloy or hard resin plate materials having holes formed at appropriate intervals are provided. Both edge members are connected to each other by a connecting portion having a mountain shape and having a hinge function, and a substantially U-shaped eaves-end fitting frame is connected to each other end edge by a connecting portion having a hinge function. By attaching the elastic metal fitting to the inner side of the mountain shape, the width of the valley cover can be easily adjusted to correspond to the distance between the eaves of the roof, so that the fitting work to the eaves becomes easy.
Also, if the valley cover is made of metal such as aluminum alloy, the snow on the roof can be melted effectively using the residual heat from the indoor heating and the heat from the groundwater, preventing damage to the roof due to snow load. be able to. Moreover, if a buffer frame is laminated | stacked on the eaves edge fitting frame, there also exists an effect that the eaves edge of a roof is not damaged.
[0028]
2. According to invention of Claim 2, in the cover installed in the upper part of the valley trough arrange | positioned at the trough part of a roof, the board | plate material made from two aluminum alloys or the hard resin which perforate | pierced the hole at appropriate intervals One end edge side is connected with a connecting portion that has a mountain-shaped hinge function, and a substantially U-shaped eaves-end fitting frame is integrally provided on each other end edge, and elastic metal fittings are provided on the inner sides of both plate materials. Since there is no rotation of the eaves fitting frame with respect to the plate material, there is no attitude adaptation to the eaves part of the roof, but the installation work is easy, and it corresponds to a wide range of valley width dimensions. be able to.
[0029]
3. According to invention of Claim 3, in addition to the effect of invention of Claim 1 or Claim 2, the edge part of any member of the two members which comprise a connection part is connected state of two members By using the screw groove portion of the screw that holds the screw, the integrity of the trough cover is not impaired. In other words, the trough cover C is not disassembled during transportation, is not damaged or lost, and is easy to handle during construction.
