Description

本開示は、被締結物に関し、より詳細には、締結具により締結される被締結物に関する。 The present disclosure relates to objects to be fastened, and more particularly to objects to be fastened by fasteners.

ボルトなどの締結具を締結させる被締結物側の構造としては、締結具の頭部の回り止めとして機能する構造が提案されている（例えば、特許文献１、２参照）。 As a structure on the side to be fastened to fasten fasteners such as bolts, a structure that functions as a detent for the head of the fastener has been proposed (see, for example, Patent Documents 1 and 2).

特開２０１３−２４１９４９号公報Japanese Unexamined Patent Publication No. 2013-241949 特開２０１４−１５２９１６号広報Japanese Patent Application Laid-Open No. 2014-152916

ところで、特許文献１、２に記載の構造において、被締結物に形成されてボルトなどの締結具を挿通可能な貫通孔が長穴状の場合に、締結具の頭部の回り止め構造のみでは、締結作業中に締結具の軸部が貫通孔の長手方向に移動するという新たな問題が生じる。締結具の軸部を長手方向に移動させずに貫通孔の所望した位置で締結させるためには、締結作業中に締結具および被締結物の両方の位置を固定して締結する必要がある。このように被締結物に形成された貫通孔が長穴状の場合には、締結作業に締結具および被締結物の両方の位置を固定すべくそれらを押え付ける手間が生じていた。 By the way, in the structure described in Patent Documents 1 and 2, when the through hole formed in the object to be fastened and through which the fastener such as a bolt can be inserted is an elongated hole, the detent structure of the head of the fastener alone is sufficient. , A new problem arises in which the shaft portion of the fastener moves in the longitudinal direction of the through hole during the fastening operation. In order to fasten at a desired position of the through hole without moving the shaft portion of the fastener in the longitudinal direction, it is necessary to fix both the positions of the fastener and the object to be fastened during the fastening operation. When the through holes formed in the object to be fastened are elongated holes in this way, it takes time and effort to press them in order to fix the positions of both the fastener and the object to be fastened in the fastening work.

本開示の目的は、位置を固定するための手間を省くことが可能な被締結物を提供することである。 An object of the present disclosure is to provide an object to be fastened, which can save the trouble of fixing the position.

上記の目的を達成する本発明の一態様の被締結物は、基体とこの基体に形成された貫通孔とを備え、前記基体が締結具の座金と面接触する基面を有し、前記貫通孔が前記締結具の軸部を挿通可能にその軸部の軸方向に見て一方向の長さがその一方向に直交する方向の長さよりも長い長穴状を成す被締結物において、前記基面から前記軸方向に向かって突出するとともに前記貫通孔の前記直交する方向に存在する両縁部のうちの一方の縁部に延在して、前記一方向における前記貫通孔の両端部のうちの一方の端部に対して面する拘束面を備え、この拘束面が前記座金の外径に基づいた距離に応じて前記一方の端部から離間した位置に配置されることを特徴とする。 An object to be fastened according to an aspect of the present invention that achieves the above object includes a base and a through hole formed in the base, and has a base surface in which the base comes into surface contact with a washer of a fastener, and the penetration. In the object to be fastened, the hole forms an elongated hole in which the length in one direction when viewed in the axial direction of the shaft portion is longer than the length in the direction orthogonal to the one direction so that the shaft portion of the fastener can be inserted. Protruding from the base surface in the axial direction and extending to one of the edges of the through hole existing in the orthogonal direction, both ends of the through hole in the one direction. It is characterized in that it is provided with a restraining surface facing one end of the washer, and the restraining surface is arranged at a position separated from the one end according to a distance based on the outer diameter of the washer. ..

本発明の一態様によれば、締結具により被締結物を締結する際に、拘束面が締結具の座金の側面に接触して締結具の軸部の移動を拘束することで、締結具の軸部の位置が貫通孔の一方の端部に固定される。これにより、締結作業時の締結具および被締結物の両方を押さえ付けて位置を固定する手間を省くことができる。 According to one aspect of the present invention, when the object to be fastened is fastened by the fastener, the restraining surface comes into contact with the side surface of the washer of the fastener to restrain the movement of the shaft portion of the fastener. The position of the shaft is fixed to one end of the through hole. As a result, it is possible to save the trouble of pressing both the fastener and the object to be fastened during the fastening work to fix the position.

The guide portion 20 has a restraint surface 21 and a guide surface 22.

ガイド部２０は端片１７を屈曲させて拘束面２１と案内面２２とが形成される。ガイド部２０は基体１１とは別体の部材で構成し、基体１１に接合したものでもよい。また、ガイド部２０は、端片１６、１７のうちの少なくとも一方に設けられればよく、両方の端片１６、１７のそれぞれに設けられてもよい。 The guide portion 20 bends the end piece 17 to form a restraint surface 21 and a guide surface 22. The guide portion 20 may be formed of a member separate from the substrate 11 and bonded to the substrate 11. Further, the guide portion 20 may be provided on at least one of the end pieces 16 and 17, and may be provided on each of both end pieces 16 and 17.

拘束面２１は、基面１３からＺ方向上方に向かって突出するとともに端片１７に延在して閉口端部１４に対して面する。また、拘束面２１は座金６の外径Ｒ１に基づいた距離に応じて閉口端部１４から離間した位置に配置される。 The restraint surface 21 projects upward in the Z direction from the base surface 13 and extends to the end piece 17 to face the closed end portion 14. Further, the restraint surface 21 is arranged at a position separated from the closed end portion 14 according to the distance based on the outer diameter R1 of the washer 6.

拘束面２１は軸部４ａが閉口端部１４に位置する状態で座金６の側面と接触する面であればよい。拘束面２１は平面に限定されずに、座金６の側面と接触する面であれば屈曲面であってもよい。 The restraint surface 21 may be a surface that comes into contact with the side surface of the washer 6 with the shaft portion 4a located at the closed end portion 14. The restraint surface 21 is not limited to a flat surface, and may be a bent surface as long as it is a surface that comes into contact with the side surface of the washer 6.

拘束面２１は基面１３に対して、換言すると、座金６の座面に対して略垂直に立てられることが好ましい。また、拘束面２１の基面１３からの高さは少なくとも座金６の厚さよりも高いことが好ましい。 It is preferable that the restraint surface 21 stands substantially perpendicular to the base surface 13, in other words, the seat surface of the washer 6. Further, the height of the restraint surface 21 from the base surface 13 is preferably at least higher than the thickness of the washer 6.

拘束面２１は端片１７に延在すればよく、端片１７の所定の位置からから貫通孔１２に対して離間する方向に向かって延在することが好ましく、端片１７を端から端まで横断するように延在することがより好ましい。また、拘束面２１は、貫通孔１２にはみ出さないように構成される。 The restraint surface 21 may extend to the end piece 17, preferably extending from a predetermined position of the end piece 17 toward a direction away from the through hole 12, and the end piece 17 extends from end to end. It is more preferable to extend so as to cross. Further, the restraint surface 21 is configured so as not to protrude into the through hole 12.

拘束面２１は閉口端部１４に面する。本開示で、拘束面２１が閉口端部１４に面するとは、閉口端部１４に位置する軸部４ａの中心を端点Ｐ１とする場合に、Ｚ方向に見て、拘束面２１がその端点Ｐ１に対して面している状態を示す。 The restraint surface 21 faces the closed end portion 14. In the present disclosure, the fact that the restraint surface 21 faces the closed end portion 14 means that when the center of the shaft portion 4a located at the closed end portion 14 is the end point P1, the restraint surface 21 faces the end point P1 when viewed in the Z direction. Indicates the state of facing to.

拘束面２１の配置位置は、座金６の外径Ｒ１に基づいた距離に応じて設定される。具体的に、その配置位置は、拘束面２１と座金６の側面とが接触した状態になった場合に、軸部４ａが閉口端部１４に位置する状態になる位置である。換言すると、その配置位置は、軸部４ａが閉口端部１４に位置する状態になった場合の座金６の外縁に対する接線位置である。 The arrangement position of the restraint surface 21 is set according to the distance based on the outer diameter R1 of the washer 6. Specifically, the arrangement position is a position where the shaft portion 4a is located at the closed end portion 14 when the restraint surface 21 and the side surface of the washer 6 are in contact with each other. In other words, the arrangement position is a tangential position with respect to the outer edge of the washer 6 when the shaft portion 4a is located at the closed end portion 14.

案内面２２は拘束面２１に対してＺ方向に隣接する面であり、ガイド部２０において拘束面２１よりもＺ方向上方に設けられた面である。案内面２２はＺ方向上端がＺ方向下端よりも閉口端部１４から離間するように配置された斜面またはＺ方向上方に凸の屈曲面で構成される。 The guide surface 22 is a surface adjacent to the restraint surface 21 in the Z direction, and is a surface provided in the guide portion 20 above the restraint surface 21 in the Z direction. The guide surface 22 is composed of a slope arranged so that the upper end in the Z direction is separated from the closed end portion 14 than the lower end in the Z direction, or a bent surface convex upward in the Z direction.

案内面２２は基面１３に対して斜めに立てられることが好ましい。案内面２２が基面１３に対して斜めに立てられる場合に、案内面２２はそのＺ方向上端がＺ方向下端よりも閉口端部１４から遠ざかる位置に配置されるとよい。案内面２２が基面１３に対して斜めに立てられることで、座金６を斜面である案内面２２を滑らせて締結具２の軸部４ａを基体１１の外縁から内側に向かって導くには有利になる。 The guide surface 22 is preferably erected at an angle with respect to the base surface 13. When the guide surface 22 is erected obliquely with respect to the base surface 13, the guide surface 22 is preferably arranged at a position where the upper end in the Z direction is farther from the closed end portion 14 than the lower end in the Z direction. In order to guide the shaft portion 4a of the fastener 2 inward from the outer edge of the base body 11 by sliding the washer 6 on the guide surface 22 which is a slope by erecting the guide surface 22 at an angle with respect to the base surface 13. It will be advantageous.

図３に例示するように、被締結物１０を締結具２によりフレーム３に締結する際に、締結具２の軸部４ａの位置がずれていても、座金６がガイド部２０の案内面２２に接触して滑り、軸部４ａが閉口端部１４に導かれる。軸部４ａが閉口端部１４に位置した状態から開口端部１５に移動しようとしても、座金６の側面が拘束面２１に接触することでその移動が拘束される。 As illustrated in FIG. 3, when the object to be fastened 10 is fastened to the frame 3 by the fastener 2, the washer 6 is the guide surface 22 of the guide portion 20 even if the position of the shaft portion 4a of the fastener 2 is displaced. The shaft portion 4a is guided to the closed end portion 14 by contacting with and sliding. Even if the shaft portion 4a is attempted to move from the closed end portion 14 to the open end portion 15, the movement is restricted by the side surface of the washer 6 coming into contact with the restraining surface 21.

以上のように、被締結物１０によれば、締結具２により被締結物１０をフレーム３に締結する際に、拘束面２１が締結具２の座金６の側面に接触して締結具２の軸部４ａの位置が貫通孔１２の閉口端部１４に固定されることで、締結作業時の締結具２および被締結物１０の両方を押さえ付けて位置を固定する手間を省くことができる。 As described above, according to the object to be fastened 10, when the object to be fastened 10 is fastened to the frame 3 by the fastener 2, the restraint surface 21 comes into contact with the side surface of the washer 6 of the fastener 2 and the fastener 2 By fixing the position of the shaft portion 4a to the closed end portion 14 of the through hole 12, it is possible to save the trouble of pressing both the fastener 2 and the object to be fastened 10 during the fastening work to fix the position.

また、被締結物１０によれば、締結具２により被締結物１０をフレーム３に締結する際に、締結具２の座金６の座面が案内面２２に接触して斜面である案内面２２を滑ることで、締結具２の軸部４ａが貫通孔１２の閉口端部１４に導かれる。このように、ガイド部２０により締結具２の軸部４ａの位置決めを行うことが可能になることで、締結作業を行う際の軸部４ａの位置決め作業に要する時間を短縮することができる。 Further, according to the object to be fastened 10, when the object to be fastened 10 is fastened to the frame 3 by the fastener 2, the seat surface of the washer 6 of the fastener 2 comes into contact with the guide surface 22 and is a slope. The shaft portion 4a of the fastener 2 is guided to the closing end portion 14 of the through hole 12 by sliding. In this way, since the guide portion 20 can position the shaft portion 4a of the fastener 2, the time required for the positioning work of the shaft portion 4a when performing the fastening work can be shortened.
