Description
本発明は、パネル状の押出形材同士を接続する押出形材の接続構造に関する。 The present invention relates to a connection structure for extruded profiles that connects panel-shaped extruded profiles together.
アルミニウム合金の押出形材の嵌合部に接着剤を塗布して押出形材同士を接続する構造が提案されている（例えば、特許文献１参照）。 A structure has been proposed in which an adhesive is applied to the mating parts of aluminum alloy extrusions to connect them together (see, for example, Patent Document 1).
また、パネル状の押出形材の接合部を相対的に回転させつつ嵌合させる接続構造が提案されている。例えば、一方の押出形材の嵌合部の係止舌片を他方の押出形材の嵌合受け部の係合溝に嵌め込み、回転中心の周りに他方の押出形材を回転させる。そして、他方の押出形材の係止片の嵌合隆起が一方の押出形材の台形状嵌合凹部に嵌まり込んで隣接する押出形材が接続される構造が提案されている（例えば、特許文献２参照）。 A connection structure has also been proposed in which the joints of panel-shaped extrusions are fitted together while rotating relative to one another. For example, the locking tongue of the fitting part of one extrusion is fitted into the engagement groove of the fitting receiver of the other extrusion, and the other extrusion is rotated around the center of rotation. A structure has also been proposed in which the fitting protuberance of the locking piece of the other extrusion fits into the trapezoidal fitting recess of the first extrusion, connecting adjacent extrusions (see, for example, Patent Document 2).
ところで、押出形材の接続強度の向上が求められている。特許文献１に記載の従来技術では、押出形材を嵌合させる際に接着剤が塗布されている面が嵌合する相手側の面に対して摺動する。このため、摺動により接着材が移動して接着剤の塗布厚さにムラが発生し、接続強度の低下や、接続位置のずれが発生する場合があった。また、特許文献２に記載の構造も嵌合の際に嵌合面が相互に摺動するので、接着剤による接続と嵌合による接続とを併用しても、接着材の移動により大きな接着強度が得られない場合や、接続位置のずれが発生する場合があった。 There is a demand for improving the connection strength of extruded profiles. In the conventional technology described in Patent Document 1, when the extruded profiles are fitted together, the surface on which the adhesive is applied slides against the mating surface. This causes the adhesive to move due to the sliding, resulting in unevenness in the thickness of the adhesive applied, which can lead to a decrease in connection strength or a shift in the connection position. In addition, in the structure described in Patent Document 2, the mating surfaces also slide against each other when fitted together, so even if a connection by adhesive and a connection by fitting are used together, there are cases in which the movement of the adhesive makes it difficult to obtain a large adhesive strength or the connection position can be shifted.
そこで、本発明は、接続強度が高く、接続位置の寸法精度の高い押出形材の接続構造を提供することを目的とする。 The present invention aims to provide a connection structure for extruded profiles that has high connection strength and high dimensional accuracy at the connection position.
本発明の押出形材の接続構造は、第１押出形材の第１端部に形成された差込部を第２押出形材の第２端部に形成された受け部に差し込んで前記第１押出形材と前記第２押出形材とを接続する押出形材の接続構造であって、前記差込部は、前記第１端部から外側に突出した平板状の第１上アームと、前記第１端部からの突出長さが前記第１上アームより短い平板状の第１下アームを含み、前記受け部は、前記第２端部から外側に突出した平板状の第２上アームと、前記第２端部からの突出長さが前記第２上アームより長い平板状の第２下アームを含み、前記第１上アームと前記第１下アームは、前記第２上アームと前記第２下アームとの間に嵌合するように配置され、前記第１上アームは、下方に凸の半円筒形状の回転係合部と、前記回転係合部から外側に延びる平板状の第１先端部とを備え、前記第１先端部が上側の第１平面を有し、前記第１下アームは、第１下先端部から下方に突出する係合爪を備え、前記第２上アームは、下側の第２平面と、第２上先端部に設けられた下方に凸の半円突部とを備え、前記第２下アームは、第２先端部に設けられた上方に突出した受け座を備え、前記受け座が上側の受け面を有し、前記回転係合部が前記半円突部の外面に回転自在に係合し、前記係合爪が前記受け座の第２端部側端に係合し、前記第１上アームが前記半円突部の周りに回転して前記第１先端部の前記第１平面が前記第２上アームの前記第２平面に接し、前記第１下アームの下面が前記第２下アームの前記受け面に接することにより、前記差込部が前記受け部に嵌合し、前記第１平面、前記第２平面、前記第１下アームの下面、又は前記受け面に予め接着剤が塗布されていること、を特徴とする。 The connection structure for extruded shapes of the present invention is a connection structure for extruded shapes in which an insertion portion formed at a first end of a first extruded shape is inserted into a receiving portion formed at a second end of a second extruded shape to connect the first extruded shape and the second extruded shape , the insertion portion including a flat first upper arm protruding outward from the first end and a flat first lower arm having a shorter protruding length from the first end than the first upper arm, the receiving portion including a flat second upper arm protruding outward from the second end and a flat second lower arm having a longer protruding length from the second end than the second upper arm, the first upper arm and the first lower arm are arranged to be fitted between the second upper arm and the second lower arm, the first upper arm includes a downwardly convex semi-cylindrical rotating engagement portion and a flat first tip portion extending outward from the rotating engagement portion, the first tip portion has a first flat surface on an upper side, the first lower arm has an engaging claw protruding downward from the first lower tip portion, the second upper arm has a second flat surface on a lower side and a downwardly convex semicircular protrusion provided on the second upper tip portion, the second lower arm has a receiving seat provided on the second tip portion and protruding upward, the receiving seat has an upper receiving surface, the rotating engagement portion rotatably engages with an outer surface of the semicircular protrusion, the engaging claw engages with a second end side end of the receiving seat, the first upper arm rotates around the semicircular protrusion so that the first flat surface of the first tip portion contacts the second flat surface of the second upper arm and a lower surface of the first lower arm contacts the receiving surface of the second lower arm, thereby fitting the insertion portion into the receiving portion, and an adhesive is applied in advance to the first flat surface , the second flat surface, the lower surface of the first lower arm, or the receiving surface .
このように、差込部を受け部に嵌合させる際に、接着剤が予め塗布されている第１平面、第２平面、第１下アームの下面、又は受け面が回転摺動しないので、第１平面、第２平面、第１下アームの下面、又は受け面に予め塗布した着剤が差込部を受け部に嵌合させる際に移動することが無く接着剤の厚さにムラが発生することを抑制できる。これにより、押出形材を接続強度が高く、接続位置の寸法精度の高い状態で接続できる。 In this way, when the insert portion is fitted to the receiving portion, the first flat surface, the second flat surface, the underside of the first lower arm, or the receiving surface, to which the adhesive has been applied in advance, do not rotate and slide, so that the adhesive applied in advance to the first flat surface, the second flat surface, the underside of the first lower arm, or the receiving surface does not move when the insert portion is fitted to the receiving portion, and unevenness in the thickness of the adhesive can be suppressed. This allows the extruded profile to be connected with high connection strength and high dimensional accuracy at the connection position.
本発明の押出形材の接続構造において、前記差込部は、前記受け部に対して斜めに差し込まれた際に、前記第１上アームと前記第１下アームとが前記第２上アームと前記第２下アームに対して傾斜して対向し、前記回転係合部が前記半円突部の外面に回転自在に係合し、前記係合爪が前記受け座の前記第２端部側端に係合し、前差込部が前記受け部と並行になるように回転した際に、前記第１先端部の前記第１平面が前記第２上アームの前記第２平面に接し、前記第１下アームの下面が前記第２下アームの前記受け面に接し、これにより前記差込部が前記受け部に嵌合し、前記第１平面、又は前記第１下アームの下面に予め前記接着剤が塗布されてもよい。 In the connection structure of the extruded profile of the present invention, when the insertion portion is inserted diagonally into the receiving portion, the first upper arm and the first lower arm face each other at an angle relative to the second upper arm and the second lower arm , the rotating engagement portion rotatably engages with the outer surface of the semicircular protrusion, the engagement claw engages with the second end side end of the receiving seat, and when the front insertion portion rotates to be parallel to the receiving portion, the first plane of the first tip portion contacts the second plane of the second upper arm and the lower surface of the first lower arm contacts the receiving surface of the second lower arm, thereby fitting the insertion portion into the receiving portion, and the adhesive may be applied in advance to the first plane or the lower surface of the first lower arm .
これにより、簡便な構成で差込部が受け部に対して回転して嵌合し、且つ、回転時に接着剤が予め塗布される第１平面、又は前記第１下アームの下面が回転摺動しない構成とすることができるので、回転の際に接着剤が移動することを抑制できる。 This allows the insertion portion to rotate and engage with the receiving portion with a simple configuration, and the first plane to which adhesive is pre-applied or the underside of the first lower arm can be configured to not rotate and slide during rotation, thereby preventing the adhesive from moving during rotation.
本発明の押出形材の接続構造において、前記第１平面には、前記接着剤を貯留する第１溝が形成され、前記受け面には、前記接着剤を貯留する第２溝が形成されてもよい。 In the extruded profile connection structure of the present invention, a first groove for storing the adhesive may be formed in the first plane, and a second groove for storing the adhesive may be formed in the receiving surface.
これにより、第１平面、又は受け面の上に塗布する接着剤を回転の後に第１平面が第２平面に接するまで、及び第１下アームの下面が受け面に接するまで確実に保持することができ、接続強度が低下することを抑制できる。
This allows the adhesive applied to the first plane or the receiving surface to be securely held in place until the first plane contacts the second plane after rotation, and until the lower surface of the first lower arm contacts the receiving surface , thereby preventing a decrease in connection strength.
本発明は、接続強度が高く、接続位置の寸法精度の高い押出形材の接続構造を提供できる。 The present invention can provide a connection structure for extruded profiles that has high connection strength and high dimensional accuracy at the connection position.
以下、図１、２を参照しながら第１押出形材１００と第２押出形材２００の接合構造について説明する。図１、図２は、第１押出形材１００、第２押出形材２００を押出方向から見た断面図である。以下の説明では、図面の上方、下方をそれぞれ第１、第２押出形材１００、２００の上側、下側、図面の右方、左方をそれぞれ第１、第２押出形材１００、２００の右側、左側として説明する。 The joining structure of the first extrusion 100 and the second extrusion 200 will be described below with reference to Figures 1 and 2. Figures 1 and 2 are cross-sectional views of the first extrusion 100 and the second extrusion 200 as viewed from the extrusion direction. In the following description, the top and bottom of the drawings will be referred to as the upper and lower sides of the first and second extrusions 100 and 200, respectively, and the right and left of the drawings will be referred to as the right and left sides of the first and second extrusions 100 and 200, respectively.
図１に示す様に、第１押出形材１００は、上板１１と、下板１２と、上板１１と下板１２とを接続するリブ板１３とで構成されるパネル状部材であり、一端である左端に差込部１０が形成されている。第２押出形材２００は、上板３１と、下板３２と、上板３１と下板３２とを接続するリブ板３３とで構成されるパネル状部材であり、他端である右端に受け部３０が形成されている。第１押出形材１００の差込部１０が第２押出形材２００の受け部３０に差し込まれて係合することにより、第１押出形材１００の上板１１と下板１２とが、第２押出形材２００の上板３１と下板３２とそれぞれ同一面を構成するように接続され、例えば、車両用のフロアパネルのような一体の板状体を構成する。図２は、２枚の押出形材１００と２００が一体に固定された状態を示し、第１押出形材１００の差し込み部１０が第２押出形材２００の受け部３０の内側に差し込まれて固定された状態が示されている。 As shown in FIG. 1, the first extrusion 100 is a panel-like member composed of an upper plate 11, a lower plate 12, and a rib plate 13 connecting the upper plate 11 and the lower plate 12, and has an insertion portion 10 formed at one end, the left end. The second extrusion 200 is a panel-like member composed of an upper plate 31, a lower plate 32, and a rib plate 33 connecting the upper plate 31 and the lower plate 32, and has a receiving portion 30 formed at the other end, the right end. When the insertion portion 10 of the first extrusion 100 is inserted into and engaged with the receiving portion 30 of the second extrusion 200, the upper plate 11 and the lower plate 12 of the first extrusion 100 are connected to the upper plate 31 and the lower plate 32 of the second extrusion 200 so as to form the same surface, respectively, and form an integrated plate-like body such as a floor panel for a vehicle. FIG. 2 shows two extrusions 100 and 200 fixed together, with the insertion portion 10 of the first extrusion 100 inserted into the inside of the receiving portion 30 of the second extrusion 200 and fixed in place.
図１に示す様に、第２押出形材２００の受け部３０は、上アーム３６と、下アーム３８とで構成されている。上アーム３６は、上板３１から外側（図１中の右側）に突出した板状部材の上アーム本体３４と、上アーム本体３４の先端の下面に設けられた半円断面で押出方向に延びる突部３５とで構成されている。上アーム本体３４の上面は上板３１の上面と同一面であり、上アーム本体３４の下面は平らな上第２平面３７を構成する。このように、上アーム３６は、上第２平面３７と突部３５とを含む受アームを構成する。下アーム３８は、下板３２から外側（図１中の右側）に突出した板状部材の下アーム本体３８ａと、下アーム本体３８ａの先端の上面に設けられた受け座３９とで構成されている。受け座３９は、長方形断面で押出方向に延びる突条部である。下アーム本体３８ａの下面は、下板３２の下面と同一面であり、受け座３９の上面は、平らな下第２平面３９ａを構成する。下アーム３８の受け座３９の先端面４１は、上アーム３６の先端の突部３５よりも外側（図１中の右側）に突出している。また、受け座３９の上面には接着剤５０を貯留する溝４０が設けられている。 As shown in FIG. 1, the receiving portion 30 of the second extrusion profile 200 is composed of an upper arm 36 and a lower arm 38. The upper arm 36 is composed of an upper arm body 34 of a plate-like member protruding outward (to the right in FIG. 1) from the upper plate 31, and a protrusion 35 that has a semicircular cross section and extends in the extrusion direction and is provided on the lower surface of the tip of the upper arm body 34. The upper surface of the upper arm body 34 is flush with the upper surface of the upper plate 31, and the lower surface of the upper arm body 34 forms a flat upper second plane 37. In this way, the upper arm 36 forms a receiving arm including the upper second plane 37 and the protrusion 35. The lower arm 38 is composed of a lower arm body 38a of a plate-like member protruding outward (to the right in FIG. 1) from the lower plate 32, and a receiving seat 39 provided on the upper surface of the tip of the lower arm body 38a. The receiving seat 39 is a protrusion that has a rectangular cross section and extends in the extrusion direction. The lower surface of the lower arm body 38a is flush with the lower surface of the lower plate 32, and the upper surface of the receiving seat 39 forms a flat lower second plane 39a. The tip surface 41 of the receiving seat 39 of the lower arm 38 protrudes outward (to the right in FIG. 1) beyond the protrusion 35 at the tip of the upper arm 36. In addition, a groove 40 for storing adhesive 50 is provided on the upper surface of the receiving seat 39.
従って、受け座３９の上面である下第２平面３９ａは図１における差し込み部１０の回転時には下アーム２１の係合爪２２の先端が摺動する面を形成し、また下第２平面３９ａが下アーム２１の下第１平面２１ａと接し、接着剤５０が拡散するときの接着面を形成する。 Therefore, the lower second plane 39a, which is the upper surface of the receiving seat 39, forms the surface against which the tip of the engagement claw 22 of the lower arm 21 slides when the insertion portion 10 in FIG. 1 rotates, and the lower second plane 39a comes into contact with the lower first plane 21a of the lower arm 21 to form an adhesive surface against which the adhesive 50 spreads.
第１押出形材１００の差込部１０は、上アーム１８と、下アーム２１とで構成されている。上アーム１８は、上アーム本体１４と、回転係合部１５と、先端部１７とで構成されている。上アーム本体１４は、上面が上板１１の上面と同一面で、上板１１から外側（図１中の左側）に向かって突出する板状部材である。回転係合部１５は、上アーム本体１４の先端側に形成される半円筒部材であり、内面１６が第２押出形材２００の受け部３０の突部３５の外面に回転自在に係合する凹部を構成する。先端部１７は、回転係合部１５から外側に突出した平板状の部材である。先端部１７の上面は上板１１、上アーム本体１４の上面よりも第２押出形材２００の上アーム３６の上面と上第２平面３７との距離だけ下側に位置した平らな上第１平面１９を構成する。下アーム２１は、リブ板１３の外側面から外側（図１中の左側）に向かって突出する板状部材であり、先端に係合爪２２が形成されている。下アーム２１の下面は、第２押出形材２００の下アーム３８の下面と下第２平面３９ａとの距離だけ上方に位置する平らな下第１平面２１ａを構成する。上アーム１８の先端部１７の上第１平面１９と下アーム２１の下第１平面２１ａとの上下方向の距離は、第２押出形材２００の上アーム３６の上第２平面３７と下アーム３８の下第２平面３９ａとの距離よりも僅かに大きくなるように構成されている。このため、差し込み部１０が受け部３０に差し込まれた図２の状態では、受け部３０の上アーム３６と下アーム３８が差し込み部１０の上アーム１８と下アーム２１とをしっかりと挟み込んで固定することができる。 The insertion portion 10 of the first extrusion 100 is composed of an upper arm 18 and a lower arm 21. The upper arm 18 is composed of an upper arm body 14, a rotational engagement portion 15, and a tip portion 17. The upper arm body 14 is a plate-like member whose upper surface is flush with the upper surface of the upper plate 11 and protrudes outward (to the left in FIG. 1) from the upper plate 11. The rotational engagement portion 15 is a semi-cylindrical member formed on the tip side of the upper arm body 14, and its inner surface 16 forms a recess that rotatably engages with the outer surface of the protrusion 35 of the receiving portion 30 of the second extrusion 200. The tip portion 17 is a flat member that protrudes outward from the rotational engagement portion 15. The upper surface of the tip portion 17 forms a flat upper first plane 19 located lower than the upper plate 11 and the upper surface of the upper arm body 14 by the distance between the upper surface of the upper arm 36 of the second extrusion 200 and the upper second plane 37. The lower arm 21 is a plate-like member that protrudes from the outer surface of the rib plate 13 toward the outside (left side in FIG. 1), and an engagement claw 22 is formed at the tip. The lower surface of the lower arm 21 forms a flat lower first plane 21a located above the distance between the lower surface of the lower arm 38 of the second extrusion 200 and the lower second plane 39a. The vertical distance between the upper first plane 19 of the tip 17 of the upper arm 18 and the lower first plane 21a of the lower arm 21 is configured to be slightly larger than the distance between the upper second plane 37 of the upper arm 36 of the second extrusion 200 and the lower second plane 39a of the lower arm 38. Therefore, in the state of FIG. 2 where the insertion portion 10 is inserted into the receiving portion 30, the upper arm 36 and the lower arm 38 of the receiving portion 30 can be firmly clamped and fixed to the upper arm 18 and the lower arm 21 of the insertion portion 10.
次に第１押出形材１００の差込部１０を第２押出形材２００の受け部３０に接続する工程について説明する。 Next, we will explain the process of connecting the insertion portion 10 of the first extrusion profile 100 to the receiving portion 30 of the second extrusion profile 200.
最初に、第１押出形材１００の差込部１０の上第１平面１９に設けられた溝２０と、第２押出形材２００の受け部３０の下第２平面３９ａの上の溝４０とに接着剤５０を塗布しておく。 First, adhesive 50 is applied to the groove 20 on the upper first plane 19 of the insertion portion 10 of the first extrusion profile 100 and to the groove 40 on the lower second plane 39a of the receiving portion 30 of the second extrusion profile 200.
次に、第１押出形材１００の差込部１０を第２押出形材２００の受け部３０に斜めに差し込んで、差込部１０の上アーム１８の回転係合部１５の内面１６を受け部３０の突部３５の外面に係合させる。また、差込部１０の下アーム２１の係合爪２２の先端を下第２平面３９ａの上に接するように配置する。この際、係合爪２２の先端は、下第２平面３９ａの溝４０よりも第２押出形材２００の側に接する。この状態では、差込部１０の上第１平面１９は、受け部３０の上第２平面３７に対して傾斜して対向し、差込部１０の下第１平面２１ａは受け部３０の下第２平面３９ａに対して傾斜して対向している。 Next, the insertion portion 10 of the first extrusion 100 is inserted obliquely into the receiving portion 30 of the second extrusion 200, and the inner surface 16 of the rotational engagement portion 15 of the upper arm 18 of the insertion portion 10 is engaged with the outer surface of the protrusion 35 of the receiving portion 30. In addition, the tip of the engagement claw 22 of the lower arm 21 of the insertion portion 10 is positioned so as to contact the top of the lower second plane 39a. At this time, the tip of the engagement claw 22 contacts the second extrusion 200 side of the groove 40 of the lower second plane 39a. In this state, the upper first plane 19 of the insertion portion 10 faces the upper second plane 37 of the receiving portion 30 at an angle, and the lower first plane 21a of the insertion portion 10 faces the lower second plane 39a of the receiving portion 30 at an angle.
第１押出形材１００を図１に示す矢印９１に示す様に時計方向に移動させると、差込部１０の回転係合部１５は受け部３０の突部３５の外面を回転摺動する。また、係合爪２２は、下第２平面３９ａの溝４０よりも左側の部分の上を第２押出形材２００に向かって摺動する。そして、図２に示す様に、差込部１０の上第１平面１９が受け部３０の上第２平面３７に接すると同時に、差込部１０の下第１平面２１ａが受け部３０の下第２平面３９ａに接すると共に差込部１０の係合爪２２が受け部３０の受け座３９の左側端に係合する。また、差込部１０の下板１２の端面２３が受け部３０の下アーム３８の先端面４１に接する。これにより、差込部１０が受け部３０に嵌合する。このように、第１押出形材１００を回転させている間、接着剤５０が塗布された上第１平面１９は回転摺動しないので接着剤５０が上第１平面１９の上を移動することがない。また、係合爪２２は、下第２平面３９ａの溝４０よりも左側の部分の上を摺動するので、下第２平面３９ａの溝４０に塗布した接着剤５０を移動させることがない。 When the first extrusion 100 is moved clockwise as shown by the arrow 91 in FIG. 1, the rotational engagement portion 15 of the insertion portion 10 rotates and slides on the outer surface of the protrusion 35 of the receiving portion 30. Also, the engagement claw 22 slides toward the second extrusion 200 on the portion to the left of the groove 40 of the lower second plane 39a. Then, as shown in FIG. 2, the upper first plane 19 of the insertion portion 10 contacts the upper second plane 37 of the receiving portion 30, and at the same time, the lower first plane 21a of the insertion portion 10 contacts the lower second plane 39a of the receiving portion 30, and the engagement claw 22 of the insertion portion 10 engages with the left end of the receiving seat 39 of the receiving portion 30. Also, the end surface 23 of the lower plate 12 of the insertion portion 10 contacts the tip surface 41 of the lower arm 38 of the receiving portion 30. As a result, the insertion portion 10 fits into the receiving portion 30. In this way, while the first extrusion profile 100 is rotating, the upper first plane 19 on which the adhesive 50 is applied does not rotate and slide, so the adhesive 50 does not move on the upper first plane 19. Also, the engagement claw 22 slides on the portion to the left of the groove 40 on the lower second plane 39a, so the adhesive 50 applied to the groove 40 on the lower second plane 39a is not moved.
先に説明したように、上アーム１８の上第１平面１９と下アーム２１の下第１平面２１ａとの上下方向の距離は、上アーム３６の上第２平面３７と下アーム３８の下第２平面３９ａとの距離よりも僅かに大きくなるように構成されている。このため、差込部１０の上アーム１８と下アーム２１は受け部３０の上アーム３６と下アーム３８とを上下方向に開く方向に付勢する。この付勢力により、差込部１０の上第１平面１９は、受け部３０の上第２平面３７に圧着し、溝２０に塗布されていた接着剤５０は、上第１平面１９と上第２平面３７との間に薄く均一に広がる。同様に、差込部１０の下第１平面２１ａは、受け部３０の下第２平面３９ａに圧着し、溝４０に塗布されていた接着剤５０は、下第１平面２１ａと下第２平面３９ａとの間に薄く均一に広がる。 As described above, the vertical distance between the upper first plane 19 of the upper arm 18 and the lower first plane 21a of the lower arm 21 is configured to be slightly larger than the distance between the upper second plane 37 of the upper arm 36 and the lower second plane 39a of the lower arm 38. Therefore, the upper arm 18 and the lower arm 21 of the insertion part 10 bias the upper arm 36 and the lower arm 38 of the receiving part 30 in a direction to open them in the vertical direction. Due to this biasing force, the upper first plane 19 of the insertion part 10 is pressed against the upper second plane 37 of the receiving part 30, and the adhesive 50 applied to the groove 20 spreads thinly and evenly between the upper first plane 19 and the upper second plane 37. Similarly, the lower first plane 21a of the insertion part 10 is pressed against the lower second plane 39a of the receiving part 30, and the adhesive 50 applied to the groove 40 spreads thinly and evenly between the lower first plane 21a and the lower second plane 39a.
第１押出形材１００と第２押出形材２００とは、突部３５と回転係合部１５の内面１６との係合と、受け座３９と係合爪２２の係合と、付勢力とにより嵌合状態が維持されるので、接着剤５０が硬化するまでこの状態を保持する。そして、接着剤５０が硬化すると、嵌合力と接着力とにより第１押出形材１００と第２押出形材２００とは強固に接続される。 The first extrusion 100 and the second extrusion 200 are maintained in an interlocking state by the engagement between the protrusion 35 and the inner surface 16 of the rotational engagement portion 15, the engagement between the receiving seat 39 and the engagement claw 22, and the biasing force, and this state is maintained until the adhesive 50 hardens. Then, when the adhesive 50 hardens, the first extrusion 100 and the second extrusion 200 are firmly connected by the interlocking force and the adhesive force.
以上説明したように、実施形態の接続構造は、接着剤５０が予め塗布されている上第１平面１９が回転の際に回転摺動しないので、上第１平面１９に予め塗布した接着剤５０が回転の際に移動することが無く接着剤５０の厚さにムラが発生することを抑制できる。これにより、第１押出形材１００と第２押出形材２００とを接続強度が高く、接続位置の寸法精度の高い状態で接続できる。 As described above, in the connection structure of the embodiment, the upper first plane 19 to which the adhesive 50 has been applied in advance does not slide during rotation, so the adhesive 50 applied in advance to the upper first plane 19 does not move during rotation, and unevenness in the thickness of the adhesive 50 can be suppressed. This allows the first extruded profile 100 and the second extruded profile 200 to be connected with high connection strength and high dimensional accuracy at the connection position.
また、第１押出形材１００が回転した際に、差込部１０の係合爪２２が下第２平面３９ａの溝４０よりも左側の部分の上を摺動するので、下第２平面３９ａの溝４０に塗布した接着剤５０を移動させることがない。これにより、係合爪２２が移動する際に下第２平面３９ａに塗布された接着剤５０の厚さのムラの発生を抑制して第１押出形材１００と第２押出形材２００とを接続強度が高く、接続位置の寸法精度の高い状態で接続できる。 In addition, when the first extrusion profile 100 rotates, the engagement claw 22 of the insertion portion 10 slides over the portion to the left of the groove 40 on the lower second plane 39a, so the adhesive 50 applied to the groove 40 on the lower second plane 39a is not displaced. This prevents unevenness in the thickness of the adhesive 50 applied to the lower second plane 39a from occurring when the engagement claw 22 moves, and allows the first extrusion profile 100 and the second extrusion profile 200 to be connected with high connection strength and high dimensional accuracy at the connection position.
また、接着剤５０を予め塗布する上第１平面１９と、下第２平面３９ａとに接着剤５０を貯留する溝２０、４０を設けたので、上第１平面１９、下第１平面２１ａが上第２平面３７、下第２平面３９ａにそれぞれ接するまで接着剤５０確実に保持することができる。これにより、第１押出形材１００と第２押出形材２００とを接続強度が高く、接続位置の寸法精度の高い状態で接続できる。 In addition, grooves 20, 40 for storing adhesive 50 are provided on the upper first plane 19, on which adhesive 50 is applied in advance, and the lower second plane 39a, so that adhesive 50 can be securely held until the upper first plane 19 and the lower first plane 21a come into contact with the upper second plane 37 and the lower second plane 39a, respectively. This allows the first extruded profile 100 and the second extruded profile 200 to be connected with high connection strength and high dimensional accuracy at the connection position.
以上の説明では、接着剤５０は、上第１平面１９の上に予め塗布しておくこととして説明したが、これに限らず、第１押出形材１００が回転した際に回転摺動しない上第２平面３７の上に予め塗布してもよい。また、第１押出形材１００が回転した際に下第２平面３９ａの上を摺動しない下第１平面２１ａに接着剤５０を予め塗布してもよい。 In the above explanation, the adhesive 50 is described as being applied in advance to the upper first plane 19, but this is not limited thereto, and the adhesive 50 may be applied in advance to the upper second plane 37, which does not slide when the first extruded profile 100 rotates. Also, the adhesive 50 may be applied in advance to the lower first plane 21a, which does not slide on the lower second plane 39a when the first extruded profile 100 rotates.
また、上第１平面１９または上第２平面３７のいずれか一方または両方に接着剤５０を予め塗布し、下第１平面２１ａ、下第２平面３９ａには予め接着剤５０を塗布しなくてもよい。 Also, adhesive 50 may be applied in advance to either or both of upper first plane 19 and upper second plane 37, and adhesive 50 may not be applied in advance to lower first plane 21a and lower second plane 39a.
