Description

本発明は、互いに組み付けられて内部に配線・配管材の配設経路を形成する基台と蓋体とから成り、当該配設経路に沿った端部の接続口に、長尺の直状保護カバー又は別の保護カバー接続体が接続される保護カバー接続体、及びその組付け構造に関するものである。 The present invention comprises a base and a lid that are assembled to each other to form an arrangement path for wiring / piping material inside, and a long straight protection is provided at a connection port at an end along the arrangement path. It relates to a protective cover connector to which a cover or another protective cover connector is connected, and an assembly structure thereof.

上記した保護カバー接続体の基台と蓋体とは、特許文献１に示されるように、当該基台に設けられた被係合部に対してオーバーハング状となって配置されるように、当該蓋体の側壁の内側に設けられた係合部と前記被係合部との係合により、一体に組み付けられる。また、当該係合の解除は、係合部が設けられている部分の蓋体の側壁の内側に配設経路に沿った撓み空間を形成して、当該撓み空間を利用して、蓋体の側壁を内方に撓ませて行っている。 As shown in Patent Document 1, the base and lid of the protective cover connection body described above are arranged in an overhang shape with respect to the engaged portion provided on the base. It is integrally assembled by engaging the engaging portion provided inside the side wall of the lid body and the engaged portion. Further, in the disengagement, a bending space along the arrangement path is formed inside the side wall of the lid of the portion where the engaging portion is provided, and the bending space is used to utilize the bending space of the lid. The side wall is bent inward.

このため、保護カバー接続体が小型化された場合には、蓋体の側壁の配設方向に沿った寸法が短くなって、側壁の内側の配設経路に沿った方向に十分な長さの撓み空間を形成できなくなる。 Therefore, when the protective cover connecting body is miniaturized, the dimension along the arrangement direction of the side wall of the lid is shortened, and the length is sufficient in the direction along the arrangement path inside the side wall. It becomes impossible to form a flexible space.

The lid body includes a top wall that is fixed to the wall surface and faces the base, and a pair of side walls that are arranged to face each other with the top wall side as the base end and the wall surface side as the tip.
The base is arranged so as to face each other in a state where the engaged plate portions are vertically erected at both ends in the width direction, and the engaged portions are formed inside each of the engaged plate portions. ,
Inside the side wall, an engaging portion that engages with the engaged portion of the base in an overhang shape is provided.
When the space between the base end on the top wall side and the tip on the wall surface side of the side wall is bent inward, the side wall comes into contact with the tip end side of the side wall in which the engaging portion is formed on the inner surface side. and restrict the movement of the distal end side inward deformation space formed protrusion for forming a deformation space to the inside of the side wall is found provided on the base,
Between the inner surface of each side wall of the lid and each of the engaged plate portions, a bending space for increasing the amount of bending deformation inward of the side wall is provided from the base side to the top wall side of the lid. It is characterized in that it is formed with a constant width along the height direction of the side wall toward the side.

請求項１の発明によれば、基台の被係合部と蓋体の係合部とが係合されて、当該基台に対して蓋体が覆蓋された状態では、基台に設けられた撓み空間形成突部に対して蓋体の側壁の先端は、近接又は当接している。前記係合を解除するには、蓋体の側壁の基端と先端との中間部（当該側壁の高さ方向の中間部）を内方に押圧すると、当該蓋体の側壁の先端は、基台の撓み空間形成突部に押圧されて、内方への移動が規制された状態で、当該側壁の基端と先端との間が撓み変形される。このため、前記係合の解除に必要な蓋体の側壁の撓み変形量を確保できて、蓋体の側壁における係合部が設けられた部分の撓み量を大きくできて、前記係合の解除を確実に行える。 According to the invention of claim 1, when the engaged portion of the base and the engaging portion of the lid are engaged and the lid is covered with respect to the base, the base is provided on the base. The tip of the side wall of the lid is close to or in contact with the bent space forming protrusion. To disengage the engagement, the intermediate portion between the base end and the tip of the side wall of the lid (the middle portion in the height direction of the side wall) is pressed inward, and the tip of the side wall of the lid is pressed. The space between the base end and the tip of the side wall is flexed and deformed in a state where the inward movement is restricted by being pressed by the bending space forming protrusion of the table. Therefore, the amount of bending deformation of the side wall of the lid required for disengaging the engagement can be secured, and the amount of bending of the portion of the side wall of the lid provided with the engaging portion can be increased, and the disengagement can be disengaged. Can be done reliably.

このように、請求項１の発明によれば、基台における蓋体の側壁の先端に対応する部分に、当該側壁の先端の内方への移動を規制する撓み空間形成突部を設けることで、蓋体の側壁の内側に、当該蓋体の高さ方向に沿った撓み空間が形成されて、当該側壁の高さ方向に沿った撓み変形を大きくできるため、当該側壁の配設経路に沿った寸法が短くて、当該配設経路に沿って蓋体の側壁の撓み空間を形成する寸法がない場合、即ち、小型の保護カバー接続体においても、蓋体の側壁に配設経路と直交する方向に沿った撓み空間を形成することで、基台の被係合部と蓋体の係合部との係合の解除を確実に行える。 As described above, according to the invention of claim 1, the bending space forming protrusion that regulates the inward movement of the tip of the side wall is provided in the portion of the base corresponding to the tip of the side wall of the lid. , A bending space along the height direction of the lid is formed inside the side wall of the lid, and the bending deformation along the height direction of the side wall can be increased.

次に、図６、図８〜図１０を参照して蓋体Ｌ1 について説明する。蓋体Ｌ1 は、出隅Ａの形状に対応して、側面視でＬ字状をなしていて、縦断面視（配設経路Ｒに沿った断面視）でＬ字形をした天壁１１の幅方向の両端である基端から、各壁面Ｗ1 ，Ｗ2 に対向する先端に向けて各側壁１２，１３が垂直となって一体に形成されることで、各側壁１２，１３の側面形状（合成形状）がＬ字状をなしている。各側壁１２，１３は、いずれも前記基台Ｖ1 の幅方向に沿った長さに対応する間隔をおいた一対で構成される。これにより、蓋体Ｌ1 の配設経路Ｒに沿った両端には、直状保護カバーＣ0 又は別の保護カバー接続体Ｃ2 が接続される接続口１４ａ，１４ｂがそれぞれ形成される。基台Ｖ1 との組付け状態で、内側に当該基台Ｖ1 の被係合部Ｆ1 が配置される一対の側壁１２の内面には、当該各側壁１２との間に所定間隔をおいて係合部形成板部１５が、互いに直交する各連結板部１６，１７を介して一体に形成されている。係合部形成板部１５と各連結板部１６，１７で囲まれる空間は、係合空間１８を形成していて、当該係合空間１８は、前記接続口１４ａの側と、一対の側壁１２の各先端の側に開口〔以下、当該開口を「被係合部挿入開口１９（図６参照）」という〕されている。係合部形成板部１５の内面における連結板部１６に近い側には、基台Ｖ1 の被係合部Ｆ1 と係合される突条状の係合部Ｅ1 が天壁１１と平行に突設されている。 Next, the lid L 1 will be described with reference to FIGS. 6, 8 to 10. The lid L 1 has an L-shape in the side view corresponding to the shape of the protruding corner A, and the top wall 11 has an L-shape in the vertical cross-sectional view (cross-sectional view along the arrangement path R). The side surface shapes of the side walls 12 and 13 are formed by forming the side walls 12 and 13 vertically from the base ends, which are both ends in the width direction , toward the tips facing the wall surfaces W 1 and W 2. (Synthetic shape) is L-shaped. Each side wall 12,13 consists either of a pair of spaced corresponding to the length along the width direction of the base V 1. As a result, connection ports 14a and 14b to which the straight protective cover C 0 or another protective cover connecting body C 2 is connected are formed at both ends of the lid L 1 along the arrangement path R, respectively. In the assembled state of the base V 1, the inner surfaces of the pair of side walls 12 which engaged portion F 1 of the base V 1 is disposed inside, your predetermined distance between the respective side walls 12 The engaging portion forming plate portion 15 is integrally formed via the connecting plate portions 16 and 17 that are orthogonal to each other. The space surrounded by the engaging portion forming plate portion 15 and the connecting plate portions 16 and 17 forms an engaging space 18, and the engaging space 18 is the side of the connection port 14a and a pair of side walls 12. [Hereinafter, the opening is referred to as "engaged portion insertion opening 19 (see FIG. 6)"]. Closer to the connecting plate portion 16 in the inner surface of the engaging portion forming plate 15, protrusion engaging portions E 1 to be engaged with the engaged portion F 1 of the base V 1 is the top wall 11 and It is projected in parallel.

また、基台Ｖ1 の被係合部Ｆ1 と蓋体Ｌ1 の係合部Ｅ1 との係合を解除する際には、図１１に示されるように、当該蓋体Ｌ1 の各側壁１２の高さ方向の中央部に内方への押圧力Ｇが作用すると、各側壁１２における天壁１１と接続される基端１２ａと、壁面Ｗ1 に近接する側の先端１２ｂとの間は、当該側壁１２の先端１２ｂが、基台Ｖ1 の撓み空間形成突部９に押圧状態で当接することで、同図で二点鎖線で示されるように、内側に撓み変形される。よって、基台Ｖ1 に設けられた撓み空間形成突部９の存在により、基台Ｖ1 の被係合部形成板部２と、蓋体Ｌ1 の側壁１２の下端部との間に形成される空間は、当該側壁１２の高さ方向に沿った撓み空間２１となっている。 Further, when releasing the engagement between the engaged portion F 1 and the engaging portion E 1 of the lid L 1 of the base V 1 was, as shown in FIG. 11, each of the lid L 1 during the acting pressing force G inward in the central portion in the height direction of the side wall 12, a base end 12a connected to the top wall 11 in each side wall 12, the side of the tip 12b adjacent to the wall surface W 1 the tip 12b of the side wall 12, by abutting with the deformation space formed protrusions 9 in the pressing state of the base V 1, as shown by two-dot chain line in the drawing, is deformed inwardly.

Therefore, the thickness of each of the pair of side walls 13 and the portion of the top wall 11 connecting the pair of side walls 13 is the same as the thickness of the pair of side walls 12 and the top wall 11 of the other portion, but the pair. It is planned that the lid L 2 of the inside corner protection cover connecting body C 2 will be arranged on the side wall 13 of the side wall 13 and the outside of the top wall 11 of the corresponding portion, and the entire side wall 13 keeps the same wall thickness. And it is arranged slightly inward. Therefore, a continuous step 22 is formed at the connecting portion between the pair of side walls 12 and the pair of side walls 13 and the connecting portion of the top wall 11 corresponding to the connecting portion. If the directly external corner protective cover connector C 1 to the inside corner protective cover connector C 2 is connected, a pair of side walls 13 of the lid L 1 of external corner protective cover connectors C 1, internal corner protection A situation occurs in which the side wall 41 of the cover body L 2 of the cover connecting body C 2 interferes with the side wall 41 along the direction of the arrangement path R. Therefore, in order to deal with this situation, the pair of side walls 13 and the top wall In order to adjust the length of the portion corresponding to the pair of side walls 13 in 11 along the arrangement path R, the inner peripheral surface of the pair of side walls 13 and the portion corresponding to the pair of side walls 13 in the top wall 11 , A large number of folding grooves 23 are formed at regular intervals along the direction of the arrangement path R.
