Description

この発明は、電気ケーブル等を収納するダクトの蓋止め金具に関するものである。   The present invention relates to a lid stopper for a duct for storing an electric cable or the like.

従来より、電気ケーブル等を収納するダクトにおいて、ダクト本体５１に蓋体５２を固定する蓋止め金具として、図６に示すように、座体１１と保持体１２とから成るものが使用されている。   2. Description of the Related Art Conventionally, in a duct for storing an electric cable or the like, as a lid stopper for fixing a lid body 52 to a duct body 51, as shown in FIG. 6, a construction comprising a seat body 11 and a holding body 12 has been used. .

この座体１１は、金属の板材を曲げて、座板部１３の両側にダクトの反対側へ向かう脇板部１４を連設し、脇板部１４から係止片１５を突出させ、座板部１３に円形のボルト穴１６を穿設した構成とされている。   The seat body 11 is formed by bending a metal plate material, connecting side plate portions 14 facing the opposite side of the duct on both sides of the seat plate portion 13, and projecting locking pieces 15 from the side plate portions 14. A circular bolt hole 16 is formed in the portion 13.

また、保持体１２は、金属の板材を曲げて、ステム部１７とフック部１８とを形成すると共に、ステム部１７からフック部１８へかけて、その両側にダクト側へ向かうフランジ１９を形成し、ステム部１７に長さ方向に延びるボルト穴２０と、その両側方に位置する係止穴２１とを穿設した構成とされている。   The holding body 12 bends a metal plate material to form a stem portion 17 and a hook portion 18, and forms flanges 19 from the stem portion 17 to the hook portion 18 toward the duct side on both sides thereof. The stem portion 17 has a bolt hole 20 extending in the length direction and locking holes 21 located on both sides thereof.

このような蓋止め金具を使用して、図７に示すように、ダクト本体５１に蓋体５２を固定するには、ダクト本体５１の側板部５４に貫穴５７を穿設しておき、側板部５４の外面に座体１１の座板部１３を沿わせて、貫穴５７とボルト穴１６とを一致させる。   In order to fix the lid body 52 to the duct body 51 using such a lid stopper, as shown in FIG. 7, a through hole 57 is formed in the side plate portion 54 of the duct body 51, and the side plate The through hole 57 and the bolt hole 16 are aligned with the seat plate 13 of the seat 11 along the outer surface of the portion 54.

次に、側板部５４の内側からボルト２２を貫穴５７及びボルト穴１６に差し込み、対向する脇板部１４の間に挿入して回転が規制されたナット２３にボルト２２をねじ込んで締め付け、座体１１をダクト本体５１に固定する。   Next, the bolt 22 is inserted into the through-hole 57 and the bolt hole 16 from the inside of the side plate portion 54, and is inserted between the opposite side plate portions 14 to be screwed into the nut 23 whose rotation is restricted, and tightened. The body 11 is fixed to the duct body 51.

そして、座体１１に保持体１２を嵌め、係止片１５を係止穴２１に係合させつつ、ボルト穴２０にボルト２２を差し込み、フック部１８の先端側を蓋体５２の蓋板部５５に当接させ、ボルト２２にワッシャ２４を挿通し、ナット２５をねじ込んで、抜止用のＥリング２６を嵌める。   Then, the holding body 12 is fitted to the seat body 11, the bolt 22 is inserted into the bolt hole 20 while the locking piece 15 is engaged with the locking hole 21, and the tip end side of the hook portion 18 is connected to the lid plate portion of the lid body 52. The washer 24 is inserted into the bolt 22, the nut 25 is screwed in, and the E-ring 26 for retaining is fitted.

一方、電気ケーブルの入れ替え等に際し、ダクト本体５１から蓋体５２を取り外す場合には、図８に示すように、ナット２５を緩めて、保持体１２をボルト穴２０に沿って引き上げ、外側へ揺動させて退避させる。   On the other hand, when the lid 52 is removed from the duct body 51 when the electric cable is replaced, as shown in FIG. 8, the nut 25 is loosened, the holding body 12 is pulled up along the bolt hole 20, and is swung outward. Move to evacuate.

しかしながら、上記のような蓋止め金具では、座体１１と保持体１２との上下方向の位置関係が係止片１５と係止穴２１との係合で決定されることから、ダクト本体５１に貫穴５７を穿設する際、厳密に位置決めして、座体１１を所定の位置に取り付けておかなければ、蓋体５２がガタついたり、保持体１２で蓋体５２を抱持できなくなる虞がある。   However, in the lid stopper as described above, the vertical positional relationship between the seat body 11 and the holding body 12 is determined by the engagement between the locking piece 15 and the locking hole 21. When the through hole 57 is drilled, the lid body 52 may be rattled or the lid body 52 may not be held by the holding body 12 unless the seat body 11 is precisely positioned and attached to a predetermined position. There is.

また、ダクト本体５１への座体１１の取り付けに際し、座体１１に対してナット２３を回転させることができないので、ダクト本体５１の内側からレンチ等を使用してボルト２２を締め付けなければならず、作業性がよくないという問題がある。   Further, since the nut 23 cannot be rotated with respect to the seat body 11 when the seat body 11 is attached to the duct body 51, the bolt 22 must be tightened using a wrench or the like from the inside of the duct body 51. There is a problem that workability is not good.

さらに、ダクト本体５１の内部がドライバーを幅方向に向けて入れられないくらい狭い場合、ボルト２２として、丸みを帯びた頭部にすり割りや十字穴を有する小ねじを使用することができず、六角ボルトの角部でケーブルの被覆が傷付いたりする虞がある。   Furthermore, if the inside of the duct body 51 is so narrow that the driver cannot be put in the width direction, the bolt 22 cannot use a machine screw having a slot or a cross hole on the rounded head, There is a risk that the cable sheath may be damaged at the corners of the hexagon bolts.

また、ダクト本体５１から蓋体５２を取り外す際、退避させていた保持体１２が不意に戻ってしまい、蓋体５２を再度取り付ける作業に支障を来たすことがある。   Moreover, when removing the cover body 52 from the duct main body 51, the retracted holding body 12 may return unexpectedly, which may hinder the work of reattaching the cover body 52.

そのほか、座体１１の製作や取り付けに手間がかかり、蓋止め金具の供給やダクトの設置・保守等に伴うコストが高くなるという問題もある。   In addition, it takes time to manufacture and attach the seat body 11, and there is a problem that the cost associated with the supply of the lid stopper and the installation / maintenance of the duct increases.

そこで、この発明は、ダクト本体と蓋体とを堅固かつ容易に固定でき、電気ケーブルの保護性に優れ、コストを抑制できるダクトの蓋止め金具を提供することを課題とする。   Therefore, an object of the present invention is to provide a duct lid stopper that can firmly and easily fix the duct main body and the lid, is excellent in electrical cable protection, and can suppress costs.

上記課題を解決するため、この発明に係るダクトの蓋止め金具は、ステム部からフック部へかけてダクト側に設けたフランジに、ステム部の基端側で膨出する支点部を形成し、支点部をダクト本体の側板部に当接させ、側板部を貫通したボルトに対し、ステム部の長さ方向に延びるボルト穴に沿ってスライド可能な状態で、ボルト穴から突出したボルトにナットをねじ込んで締め付けると、ステム部が揺動してフランジが蓋体の外嵌部に押し付けられると共に、フック部の先端側が蓋板部に押し付けられるようにしたのである。   In order to solve the above-mentioned problem, a lid stopper for a duct according to the present invention forms a fulcrum portion that bulges on the proximal end side of the stem portion on a flange provided on the duct side from the stem portion to the hook portion, The fulcrum part is brought into contact with the side plate part of the duct body, and the nut projecting from the bolt hole with the bolt penetrating the side plate part being slidable along the bolt hole extending in the length direction of the stem part. When screwed and tightened, the stem portion swings and the flange is pressed against the outer fitting portion of the lid body, and the tip side of the hook portion is pressed against the lid plate portion.

この発明に係るダクトの蓋止め金具では、ナットの締め付けに伴い、蓋体の外嵌部がステム部のフランジに押圧されて、ダクト本体の側板部外面に密着すると共に、蓋体の蓋板部がフック部の先端側に押圧されてダクト本体の側板部上端に密着するので、ダクト本体に蓋体が堅固に固定されるほか、座体が不要であることから、製造や取り付けに要するコストも低減される。   In the lid stopper for a duct according to the present invention, as the nut is tightened, the outer fitting portion of the lid body is pressed against the flange of the stem portion and closely contacts the outer surface of the side plate portion of the duct body, and the lid plate portion of the lid body Is pressed against the tip of the hook part and closely contacts the upper end of the side plate part of the duct body, so that the lid body is firmly fixed to the duct body and the seat body is unnecessary, so the cost required for manufacturing and installation is also high Reduced.

また、ダクト本体の側板部にボルトを貫通させる貫穴を開ける際、厳密に位置決めしなくても、蓋体を固定する際、ダクト本体に対し、ステム部のボルト穴に規制された範囲で蓋止め金具をスライドさせることができるので、蓋体を確実に固定でき、ダクト本体の側板部と蓋体との間に防水シールを介在させることもできる。   In addition, when opening a through-hole through which a bolt passes through the side plate of the duct body, the lid is fixed to the duct body within the range restricted by the bolt hole of the stem part when fixing the lid without strictly positioning. Since the stopper can be slid, the lid can be securely fixed, and a waterproof seal can be interposed between the side plate portion of the duct body and the lid.

さらに、ダクト本体の側板部にボルトを固定する場合にも、側板部の外側からナットを回転させることができるので、ダクト本体の内部にドライバーを挿入することなく、ボルトに丸みを帯びた頭部を有する小ねじを使用して、ケーブルを保護することができる。   Furthermore, even when bolts are fixed to the side plate part of the duct body, the nut can be rotated from the outside of the side plate part, so that the bolt is rounded without inserting a screwdriver inside the duct body. A machine screw with can be used to protect the cable.

そのほか、ダクト本体から蓋体を取り外す際には、ナットを緩めて、蓋止め金具をボルトに対し反転させてぶら下げておくことができるので、蓋体の取り外しや再度の取り付けを容易に行うことができ、ダクトの保守等における作業性が改善される。   In addition, when removing the lid from the duct body, the nut can be loosened and the lid stopper can be inverted with respect to the bolt and hung so that the lid can be easily removed or reattached. This improves the workability in duct maintenance and the like.

以下、この発明の実施形態を添付図面に基づいて説明する。この蓋止め金具を使用するダクトは、図５に示すように、ダクト本体５１に蓋体５２を被せるものであり、ダクト本体５１は、底板部５３の両側に側板部５４を連設した構成とされ、蓋体５２は、蓋板部５５の両側に外嵌部５６を連設した構成とされている。   Embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in FIG. 5, the duct using the lid stopper metal fitting is configured such that a duct body 51 is covered with a lid body 52, and the duct body 51 has a configuration in which side plate portions 54 are continuously provided on both sides of a bottom plate portion 53. The lid body 52 has a configuration in which outer fitting portions 56 are continuously provided on both sides of the lid plate portion 55.

この蓋止め金具は、図１乃至図３に示すように、金属の板材を曲げて、ステム部１とフック部２とを形成したものとされ、ステム部１の基端側及びフック部２の先端側には、それぞれ折返部１ａ，２ａが形成されている。また、ステム部１からフック部２へかけて、その両側には、ダクト側へ向かうフランジ３が設けられている。   As shown in FIGS. 1 to 3, this lid stopper is formed by bending a metal plate material to form a stem portion 1 and a hook portion 2, and the base end side of the stem portion 1 and the hook portion 2. Folded portions 1a and 2a are formed on the tip side, respectively. Further, flanges 3 directed to the duct side are provided on both sides from the stem portion 1 to the hook portion 2.

フランジ３は、ステム部１の中間部から斜めに迫り出し、その基端側には膨出する支点部３ａが形成されている。ステム部１には、長さ方向に延びるボルト穴４が穿設され、ボルト穴４は、支点部３ａの上方に対応する位置から折返部１ａの範囲に亘っている。   The flange 3 protrudes obliquely from the intermediate portion of the stem portion 1, and a fulcrum portion 3 a that swells is formed on the base end side thereof. A bolt hole 4 extending in the length direction is formed in the stem portion 1, and the bolt hole 4 extends from a position corresponding to the upper side of the fulcrum portion 3 a to the range of the folded portion 1 a.

このような蓋止め金具を使用して、ダクト本体５１に蓋体５２を固定するには、図３に示すように、ダクト本体５１の側板部５４に貫穴５７を穿設しておき、蓋体５２を被せる前に、側板部５４の内側からボルト５を貫穴５７に差し込んで外側へ貫通させ、ボルト５にワッシャ６を挿通し、ナット７をねじ込んで、側板部５４にボルト５を固定する。   In order to fix the lid body 52 to the duct main body 51 using such a lid stopper, as shown in FIG. 3, a through hole 57 is formed in the side plate portion 54 of the duct main body 51, and the lid Before covering the body 52, the bolt 5 is inserted into the through hole 57 from the inside of the side plate portion 54 to penetrate the outside, the washer 6 is inserted into the bolt 5, the nut 7 is screwed in, and the bolt 5 is fixed to the side plate portion 54. To do.

そして、ダクト本体５１に蓋体５２を被せ、蓋止め金具をボルト５にボルト穴４を介して挿通し、支点部３ａをダクト本体５１の側板部５４に当接させ、ボルト５に対し、蓋止め金具がボルト穴４に沿ってスライド可能な状態で、ボルト穴４の支点部３ａより上方の部分から突出したボルト５にワッシャ８を挿通し、ナット９をねじ込んで締め付ける。   Then, the lid body 52 is covered with the duct body 51, the lid stopper is inserted into the bolt 5 through the bolt hole 4, the fulcrum portion 3 a is brought into contact with the side plate portion 54 of the duct body 51, and the lid 5 is covered with the lid 5. In a state in which the stopper is slidable along the bolt hole 4, the washer 8 is inserted into the bolt 5 protruding from the portion above the fulcrum part 3 a of the bolt hole 4, and the nut 9 is screwed and tightened.

これに伴い、図１及び図２に示すように、ステム部１がダクト側へ揺動して、フランジ３が蓋体５２の外嵌部５６に押し付けられ、外嵌部５６がダクト本体５１の側板部５４の外面に密着すると共に、フック部２の先端側が蓋板部５５の上面に押し付けられ、蓋板部５５が側板部５４の上端を折り曲げた蓋受部５４ａに密着する。   Accordingly, as shown in FIGS. 1 and 2, the stem portion 1 swings toward the duct side, the flange 3 is pressed against the outer fitting portion 56 of the lid body 52, and the outer fitting portion 56 is moved to the duct body 51. While being in close contact with the outer surface of the side plate portion 54, the tip end side of the hook portion 2 is pressed against the upper surface of the lid plate portion 55, and the lid plate portion 55 is in close contact with the lid receiving portion 54 a obtained by bending the upper end of the side plate portion 54.
