Description

本発明は、横枠と竪枠を斜めに連結する枠体に関するものである。 The present invention relates to a frame body that obliquely connects a horizontal frame and a collar frame.

横框にアール框を使用するドアがあり、一般的な矩形枠では横框の傾斜に対応できないことから専用の枠体が必要であった。そこで従来は、図４（ａ）（ｂ）のように、上枠（横枠）２１と竪枠２３を連結するときに、竪枠２３の上枠２１と当接する側とは反対側の側壁面２３ａから連結ネジ２５を上枠２１の傾斜に合わせて斜めにねじ込むものであり、竪枠２３とネジ頭部２５ｂの間には、一端側に傾斜当接面２６ａを有し且つ他端側に鉛直当接面２６ｂを有する座金２６を挟み、座金２６の両当接面２６ａ，２６ｂが上枠２１及び竪枠２３の当接側壁面２３ｂと連結ネジ２５のネジ頭部２５ｂに対して面同士が当接するように連結するものであった。 There is a door that uses Earl ridges on the side, and a special rectangular frame is necessary because a general rectangular frame cannot cope with the inclination of the ridge. Therefore, conventionally, as shown in FIGS. 4A and 4B, when the upper frame (horizontal frame) 21 and the collar frame 23 are connected, the side opposite to the side that contacts the upper frame 21 of the collar frame 23. The connecting screw 25 is screwed obliquely from the wall surface 23a in accordance with the inclination of the upper frame 21, and has an inclined contact surface 26a on one end side between the flange frame 23 and the screw head 25b, and the other end side. A washer 26 having a vertical abutment surface 26b is sandwiched between the abutment surfaces 26a and 26b of the washer 26 so as to face the abutment side wall surface 23b of the upper frame 21 and the collar frame 23 and the screw head 25b of the connecting screw 25. They were connected so that they were in contact with each other.

上記のような枠体を組み立てるときに、あらかじめ連結ネジを座金に挿通した状態で、横枠と竪枠との当接端面にあるネジ孔にねじ込むものであったが、ネジ孔が竪枠の奥まった位置にあることから、作業者側からはネジ孔が見えなくなってしまうため、連結ネジを手探りでねじ込む必要があった。しかしながら、図４（ｂ）中の丸数字１ように、従来使用される連結ネジ２５は、軸部の略全長にわたってネジ山が設けてあり、このような連結ネジに座金を挿通してねじ回ししたときには、ネジ山と座金内径側面との摩擦抵抗が大きくなって引掛かりやすくなり、連結ネジと座金が一緒に回転してしまうことがあった。そうすると、連結ネジを横枠２１のタッピングホール３０に最後までねじ込んだときに、図４（ｂ）中の丸数字２のように、座金２６の傾斜当接面２６ａ側端部の先端２６ｃが竪枠２３の当接側壁面２３ｂに当接したままネジ頭部２５ｂで押圧され、傾斜当接面２６ａと当接側壁面２３ｂとが面同士で当接していない状態のまま連結されることがあり、そのような状態のまま上枠と縦枠が連結されても、上記のようにネジ孔が竪枠内に隠れてしまうものであったから、作業者がその状況を確認できないため、そのまま製品として出荷されてしまえば、現場に枠体を施工した後に横枠と竪枠の間に隙間が生じてガタつくなどのクレームが発生する問題があった。
本発明は、上記課題を鑑みてなされたものであり、横枠と竪枠を斜めに連結するものであっても、精度良く確実に連結できる枠体を提供することにある。 When assembling the frame as described above, the screw was inserted into the screw hole in the contact end surface of the horizontal frame and the collar frame with the connecting screw inserted in advance through the washer. Since the screw hole is not visible from the operator side because it is in a deep position, it is necessary to screw the connecting screw by hand. However, as shown by the circled number 1 in FIG. 4B, the connecting screw 25 used in the related art is provided with a screw thread over substantially the entire length of the shaft portion, and a screw washer is passed through such a connecting screw. In this case, the frictional resistance between the screw thread and the inner side surface of the washer is increased, and it becomes easy to be caught, and the connecting screw and the washer may rotate together. Then, when the connecting screw is screwed into the tapping hole 30 of the horizontal frame 21 to the end, the tip 26c of the end portion on the inclined contact surface 26a side of the washer 26 is bent as shown by the round numeral 2 in FIG. The screw head 25b is pressed while being in contact with the abutting side wall surface 23b of the frame 23, and the inclined abutting surface 26a and the abutting side wall surface 23b may be connected without contacting each other. Even if the upper frame and the vertical frame are connected in such a state, the screw hole is hidden in the frame as described above. Once shipped, there was a problem that after constructing the frame on the site, there was a gap between the horizontal frame and the eaves frame, causing a complaint.
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a frame that can be accurately and reliably connected even when the horizontal frame and the saddle frame are connected obliquely.

本発明は、竪枠と横枠と竪枠と横枠とを斜めに連結する連結ネジと座金とを備え、座金は、連結ネジのネジ頭部が当接する鉛直当接面と、竪枠に当接する傾斜当接面と、鉛直当接面と傾斜当接面の間を貫通して連結ネジの軸部が挿通する挿通孔とを有しており、連結ネジは、軸部のネジ頭部側端部にネジ山のない部分を有し、ネジ山のない部分の軸部挿通方向の長さは、挿通孔の軸部挿通方向の最長部の長さより長いものであることを特徴とする。 The present invention is provided with a connecting screw and a washer that obliquely connect the collar frame, the horizontal frame, the collar frame, and the horizontal frame, and the washer includes a vertical abutting surface on which the screw head of the coupling screw abuts, and a collar frame. The contact portion has an inclined contact surface, and an insertion hole through which the shaft portion of the connection screw passes through the vertical contact surface and the inclined contact surface, and the connection screw is a screw head of the shaft portion. The side end portion has a portion without a screw thread, and the length of the shaft portion insertion direction of the portion without the screw thread is longer than the length of the longest portion of the insertion hole in the shaft portion insertion direction.

本発明によれば、連結ネジのネジ頭部側端部に設けてあるネジ山のない部分は、座金内径の軸部挿通方向の最長部分よりも長いものであることから、アール状をなす上枠と垂直な竪枠を連結するときに、連結ネジを座金に挿通した状態でねじ込み、座金の傾斜当接面の先端部が竪枠の上枠と当接する側にある当接側壁面に到達したときに、連結ネジのねじ山のない部分が座金内径側面に位置するので、連結ネジが回転したときの連結ネジと座金との摩擦抵抗が小さくなって引掛かりがほとんどなくなる。そうすることで、座金が連結ネジの回転に影響されずに、連結ネジのみが上枠のタッピングホールにねじ込まれていき、このときにネジ頭部で鉛直当接面を押された座金は、次第に竪枠の当接側壁面に引き寄せられて挿通した軸部を軸として回転し、傾斜当接面が面同士で当接する。このことから、枠組みのときに、ネジ孔が作業者側から見えない状態にあっても座金の傾斜当接面が竪枠に確実に面同士で当接するので、上枠と竪枠がガタツキなく精度よく確実に連結された枠体を提供できる。 According to the present invention, the non-threaded portion provided at the screw head side end portion of the connecting screw is longer than the longest portion in the shaft portion insertion direction of the washer inner diameter. When the vertical frame is connected, the connecting screw is screwed into the washer and the tip of the inclined contact surface of the washer reaches the contact side wall surface on the side that contacts the upper frame of the frame. Sometimes, the portion of the connecting screw without the thread is located on the inner side surface of the washer, so that the frictional resistance between the connecting screw and the washer when the connecting screw rotates is reduced, and there is almost no catch. By doing so, the washer is not affected by the rotation of the connecting screw, only the connecting screw is screwed into the tapping hole of the upper frame, and at this time the washer whose vertical contact surface is pushed by the screw head is Gradually, the shaft portion that is attracted to and inserted through the contact side wall surface of the flange frame rotates about the shaft, and the inclined contact surfaces contact each other. Therefore, even when the screw holes are not visible from the operator side when the frame is used, the inclined contact surfaces of the washer reliably contact each other with the frame, so that the upper frame and the frame do not rattle. It is possible to provide a frame that is accurately and reliably connected.

And (c) is an enlarged longitudinal sectional view of B in (b), and (d) is a partially enlarged view of A in (a). It is the front view which notched.
FIGS. 2A to 2B are longitudinal sectional views showing the state of the connecting screw and the washer when the upper frame and the saddle frame are attached.

本実施による枠体は、図１（ａ）のように、中空形材からなる上枠１と下枠２と左右の竪枠３，３とを備えており、上枠１は略中央が上向きに突出した略山形状に傾斜したものであり、また、図１（ｄ）のように、竪枠３上端側の小口には小口キャップ１１が嵌合してあり、上枠１と竪枠３とのコーナー部を連続的な意匠とするもので、小口キャップ１１は、竪枠３の中空部内への連結ネジ５の挿通を妨げないように、複数の長孔１１ｂが設けてある。そして、上枠１と竪枠３を連結する連結ネジ５と座金６は、図１（ｂ）に示すように、まず、連結ネジ５は、一般的なネジと同様に軸部５ａとネジ頭部５ｂとからなっており、軸部５ａのネジ頭部５ｂ側はネジ山のない部分５ｄが設けてあり、図１（ｃ）のように、このネジ山のない部分５ｄの長さ（図１（ｃ）中のａ）は、座金の挿通孔の軸部挿通方向の最長部（図１（ｃ）中のｂ）よりも軸部挿通方向に長く形成してある。次に、座金６は、円筒状の一端側に傾斜当接面６ｂを有し、他端側に鉛直当接面６ａを有しており、その内径に有する挿通孔７は、連結ネジ５の軸部５ａよりも僅かに径が大きく形成してある。 As shown in FIG. 1A, the frame body according to the present embodiment includes an upper frame 1 and a lower frame 2 made of a hollow material, and left and right eaves frames 3 and 3, and the upper frame 1 has a substantially center upward. Further, as shown in FIG. 1 (d), a small cap 11 is fitted in the small edge on the upper end side of the collar frame 3, and the upper frame 1 and the collar frame 3. The corner cap 11 is provided with a plurality of long holes 11b so as not to prevent the connection screw 5 from being inserted into the hollow portion of the collar frame 3. As shown in FIG. 1B, the connecting screw 5 and the washer 6 for connecting the upper frame 1 and the collar frame 3 are, as shown in FIG. 5b, and the screw head 5b side of the shaft portion 5a is provided with a screw-free portion 5d. As shown in FIG. 1C, the length of the screw-free portion 5d (see FIG. A) in 1 (c) is formed longer in the shaft portion insertion direction than the longest portion (b in FIG. 1 (c)) of the washer insertion hole in the shaft portion insertion direction. Next, the washer 6 has an inclined contact surface 6b on one end side of the cylindrical shape, and a vertical contact surface 6a on the other end side. The diameter is slightly larger than that of the shaft portion 5a.

図２（ａ）〜（ｃ）に基づき、上記した連結ネジ５と座金６を使用し、上枠１と竪枠３を連結したときの連結ネジ５のねじ込まれる状態について説明する。
まず、図２（ａ）のように、上枠１と竪枠３を所定の位置で当接し、竪枠３における上枠１と当接する側とは反対側の側壁部３ａに設けてある長孔８に、あらかじめ座金６を軸部５ａに挿通してある連結ネジ５を差し込み、そのまま竪枠３の形材中空部を抜けて上枠１と当接する側の側壁部３ｂに設けてあるネジ孔９に軸部先端５ｅを挿通する。そして図２（ｂ）のように、ネジ孔９を相通した連結ネジ５の軸部先端５ｅを上枠１のタッピングホール１０にねじ込んでいくと、座金６の鉛直当接面６ａにネジ頭部５ｂが当接し、座金６の傾斜当接面６ｂ側における外形側端部の最長部６ｃが、竪枠３における上枠１と当接する側の側壁部３ｂに当接する。このとき、座金６の内径と連結ネジ５の軸部５ａのネジ山のない部分５ｃが当接するが、ネジ山５ｃがないために引掛かりがなく摩擦抵抗が小さいことから、座金６が次第に引き寄せられて傾斜当接面６ｂが上記竪枠３の側壁部３ｂの当接端面に面同士で当接し、図２（ｃ）のように、座金６の傾斜当接面６ｂと竪枠３の側壁部３ｂの当接端面、及び座金６の鉛直当接面６ａと連結ネジ５のネジ頭部５ｂがすべて面同士で当接することから、上枠１と竪枠３との確実な連結がなされる。 Based on Fig.2 (a)-(c), the above-mentioned connection screw 5 and washer 6 are used, and the state in which the connection screw 5 is screwed in when the upper frame 1 and the collar frame 3 are connected is demonstrated.
First, as shown in FIG. 2 (a), the upper frame 1 and the collar frame 3 are brought into contact with each other at a predetermined position, and the length provided on the side wall 3a on the opposite side of the collar frame 3 from the side in contact with the upper frame 1. A screw provided in the side wall 3b on the side that comes into contact with the upper frame 1 through the hollow part of the frame 3 as it is, is inserted into the hole 8 in advance with the connecting screw 5 through which the washer 6 is inserted into the shaft 5a. The shaft tip 5e is inserted through the hole 9. As shown in FIG. 2B, when the shaft tip 5e of the connecting screw 5 passing through the screw hole 9 is screwed into the tapping hole 10 of the upper frame 1, the screw head is placed on the vertical contact surface 6a of the washer 6. 5b abuts, and the longest portion 6c of the outer end on the inclined abutment surface 6b side of the washer 6 abuts on the side wall 3b on the side of the collar frame 3 that abuts the upper frame 1. At this time, the inner diameter of the washer 6 and the unthreaded portion 5c of the shaft portion 5a of the connecting screw 5 abut, but since there is no thread 5c, there is no catch and the frictional resistance is small, so the washer 6 is gradually drawn. Then, the inclined contact surface 6b comes into contact with the contact end surface of the side wall portion 3b of the collar frame 3, and the inclined contact surface 6b of the washer 6 and the sidewall of the collar frame 3 as shown in FIG. Since the contact end surface of the portion 3b and the vertical contact surface 6a of the washer 6 and the screw head 5b of the connection screw 5 are all in contact with each other, the upper frame 1 and the collar frame 3 are reliably connected. .

本発明の枠体は、上記実施のものに限らず、図３のように、連結ネジ１５として、軸部１５ａの先端部にネジ山のない部分１５ｄを設けたものでもよい。このようにすると、軸部先端側のネジ山のない部分１５ｄが竪枠３の長孔８及びネジ孔９、上枠１のタッピングホール１０の周部に引掛かることなく滑らかに挿通されていくので、連結ネジ１５のねじ込みのときのガイド的な役割を果たし、枠組み作業を円滑に行えるようになる（図１（ｄ）もあわせて参照）。尚、図３中の符号１５ｂはネジ頭部であり、１５ｃはネジ山である。 The frame body of the present invention is not limited to the above-described embodiment, and as shown in FIG. 3, a connecting screw 15 may be provided with a portion 15d without a thread at the tip of the shaft portion 15a. In this way, the thread-free portion 15d on the shaft tip side is smoothly inserted without being caught by the long hole 8 and the screw hole 9 of the collar frame 3 and the peripheral portion of the tapping hole 10 of the upper frame 1. Therefore, it serves as a guide when the connecting screw 15 is screwed in, and the frame work can be performed smoothly (see also FIG. 1D). In addition, the code | symbol 15b in FIG. 3 is a screw head, 15c is a screw thread.
