<First Embodiment>
Hereinafter, a housing 1 according to a first embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an exploded perspective view of the housing 1 of the first embodiment.
The housing 1 of the present embodiment is a box shape having a rectangular shape in plan view, with a lid 4 on the top. In the following description, each part will be described with the direction in which the long side extends in the plan view of the housing 1 as the left-right direction and the direction in which the short side extends as the front-rear direction. In addition, unless otherwise specified, the lid 4 is attached to the main body 3 and defines each direction (front and rear, left and right, up and down) in a closed state.

<全体構成>
筐体1は、地下に埋設して使用する。本実施形態において、筐体1は、量水器ボックスであり、内部に水道メータ(以下、量水器)を収容する。筐体1は、量水器ボックスとしての利用に限らず、ガスメータ、電気メータ等の地下構造物を収容し、地下構造物を保護する用途に使用できる。また、筐体1に収容する地下構造物は、上記メータ類に限らず、例えば、電気ケーブルや配管などでも良い。更に筐体1は、マンホールでも良い。筐体1がマンホールの場合の地下構造物は、マンホールから地下に降りるための梯子などを意味する。
<Overall configuration>
The housing 1 is used by being buried underground. In this embodiment, the housing | casing 1 is a water meter box, and accommodates a water meter (henceforth, water meter) inside. The housing 1 is not limited to being used as a water meter box, and can be used for applications in which underground structures such as gas meters and electric meters are accommodated and the underground structures are protected. Moreover, the underground structure accommodated in the housing | casing 1 is not restricted to the said meters, For example, an electric cable, piping, etc. may be sufficient. Further, the housing 1 may be a manhole. The underground structure when the housing 1 is a manhole means a ladder or the like for descending from the manhole to the basement.

筐体1は、箱状の本体3と板状の蓋体4とを備える。筐体1は、上側に開口する開口部7を有する。筐体1は、内部に地下構造物を収容する。筐体1の開口部7には、蓋体の基端側に位置する2つの仮想的な基準軸Jを設定する。2つの基準軸Jは、互いに平行である。本体3に対して蓋体4は、2つの基準軸Jのうち一方の周りに回転して開閉する。なお、基準軸Jは、蓋体4の仮想的な回転中心である。本体3に対する蓋体4の取り付けは、蓋体が回転する基準軸Jを選択して行う。   The housing 1 includes a box-shaped main body 3 and a plate-shaped lid body 4. The housing 1 has an opening 7 that opens upward. The housing 1 accommodates an underground structure inside. Two virtual reference axes J located on the base end side of the lid are set in the opening 7 of the housing 1. The two reference axes J are parallel to each other. The lid 4 rotates around one of the two reference axes J and opens and closes with respect to the main body 3. The reference axis J is a virtual rotation center of the lid 4. The lid 4 is attached to the main body 3 by selecting the reference axis J on which the lid rotates.

蓋体4は、本体3に脱着可能に取り付ける。蓋体4は矩形状であり、互いに対向する長辺である先端4aと基端4bとを有する。蓋体4の基端4b側には、本体3の2つの基準軸Jのうち一方が位置する。蓋体4の基端4bは、基準軸Jと平行に延びている。蓋体4は、2つの基準軸Jのうち何れか一方を仮想中心に回転して、先端4a側が昇降する。これにより、蓋体4は、本体3に対し基端4b側を中心に回動して本体3の開口部7を開閉する。なお、蓋体4の回転中心は、回転角度によって変わる場合があり、蓋体4の回動中心と基準軸Jとは必ずしも一致しない。   The lid 4 is detachably attached to the main body 3. The lid 4 has a rectangular shape and has a distal end 4a and a proximal end 4b which are long sides facing each other. One of the two reference axes J of the main body 3 is located on the base end 4 b side of the lid body 4. The base end 4 b of the lid body 4 extends in parallel with the reference axis J. The lid 4 rotates about one of the two reference axes J around the virtual center, and the tip 4a side is raised and lowered. Accordingly, the lid body 4 rotates around the base end 4 b side with respect to the main body 3 to open and close the opening 7 of the main body 3. Note that the rotation center of the lid body 4 may vary depending on the rotation angle, and the rotation center of the lid body 4 and the reference axis J do not necessarily match.

本体3は、二組の対向する蝶着ピン(凸状部)51を有する。蝶着ピン51は、本体3の内側面3aから突出する。二組の蝶着ピン51は、それぞれ対応する基準軸Jに沿って突出する。また、蓋体4は、第1の凹状部(凸状部)12と第2の凹状部22とを有する。一組の蝶着ピン51は、第1の凹状部12の内部に遊嵌して、本体3からの蓋体4の抜け出し防止機能を発揮するとともに、蓋体4の開閉をガイドする。また、他の一組の蝶着ピン51は、第2の凹状部22の内部に遊嵌して、本体3に蓋体4を簡易ロックする機能を発揮する。ここで、遊嵌とは、蝶着ピン51と第1の凹状部12(第2の凹状部22)との間に間隔(遊び)がある状態で嵌めることである。なお、遊嵌は、蝶着ピン51が第1の凹状部12又は第2の凹状部22に緩く係合するような緩合を含む。
以下、各部について詳細に説明する。
The main body 3 has two pairs of opposing butterfly pins (convex portions) 51. The hinge pin 51 protrudes from the inner side surface 3 a of the main body 3. The two pairs of hinge pins 51 protrude along the corresponding reference axis J. The lid 4 has a first concave portion (convex portion) 12 and a second concave portion 22. The pair of butterfly pins 51 are loosely fitted inside the first concave portion 12 to exhibit a function of preventing the lid body 4 from coming off from the main body 3 and guide the opening and closing of the lid body 4. The other pair of butterfly pins 51 is loosely fitted inside the second concave portion 22 and exhibits a function of simply locking the lid 4 to the main body 3. Here, the loose fitting means fitting with a space (play) between the hinge pin 51 and the first concave portion 12 (second concave portion 22). The loose fitting includes loose coupling such that the hinge pin 51 is loosely engaged with the first concave portion 12 or the second concave portion 22.
Hereinafter, each part will be described in detail.

<本体>
本体3は、底板33と枠体32と上枠31とを有し、これらを下側から順に組み立てて構成する有底筒状の箱である。本体3を構成する底板33と枠体32と上枠31とは、例えば合成樹脂で形成するが、一部またはすべてを金属で形成しても良い。

枠体32は、上枠31を支持する。枠体32は、上下面を開口する四角筒形状を有する。枠体32の左右に位置する壁面の略中央の下部には、半円状の管挿通用凹部36を形成する。枠体32の管挿通用凹部36は、底板33の管挿通用凹部35と組み合わさって円形状の孔を形成する。筐体1の内部の量水器から延びる給水管は、この孔を挿通する。
枠体32の上面には、凸部32cを形成する。凸部32cは、上枠31の下面に形成する凹部(図示略)と嵌合する。これにより、枠体32上に上枠31が組み付く。
The frame body 32 supports the upper frame 31. The frame body 32 has a quadrangular cylindrical shape that opens at the top and bottom surfaces. A semicircular pipe insertion recess 36 is formed in the lower portion of the substantially center of the wall surface located on the left and right of the frame 32. The tube insertion recess 36 of the frame 32 is combined with the tube insertion recess 35 of the bottom plate 33 to form a circular hole. A water supply pipe extending from the water meter inside the housing 1 passes through this hole.
A convex portion 32 c is formed on the upper surface of the frame body 32. The convex portion 32 c is fitted into a concave portion (not shown) formed on the lower surface of the upper frame 31. Thereby, the upper frame 31 is assembled on the frame body 32.

上枠31は、左右方向に長手方向を有する矩形環形状を有する。また、上枠31は、上側に開口部7を有する。開口部7を蓋体4が開閉する。なお、上枠31は、調整枠として筐体1を設置する場所に応じて異なる厚みの上枠31と交換可能である。   The upper frame 31 has a rectangular ring shape having a longitudinal direction in the left-right direction. The upper frame 31 has an opening 7 on the upper side. The lid 4 opens and closes the opening 7. The upper frame 31 can be replaced with an upper frame 31 having a different thickness depending on a place where the housing 1 is installed as an adjustment frame.

上枠31の上端に位置する上面30は、閉状態時の蓋体4の上面4cと略同一の高さに形成する(図8(a)参照)。また、後段において説明するように、上面30の内方縁のうち、後方に位置する後方内方縁角部30aは、完全開状態にある蓋体4を支持する(図8(b)参照)。   The upper surface 30 positioned at the upper end of the upper frame 31 is formed at substantially the same height as the upper surface 4c of the lid body 4 in the closed state (see FIG. 8A). Further, as will be described later, among the inner edges of the upper surface 30, the rear inner edge corner portion 30a located rearward supports the lid body 4 in the fully opened state (see FIG. 8B). .

前棚部41および後棚部42は、案内部47に対して左右方向内側に位置する係合受け部48を有する。係合受け部48は、後方外側に向かって後棚部42が窪む形状である。係合受け部48は、蓋体4を開状態とした場合に、後段において説明する蓋体4の係合突起6を収容する。   The front shelf portion 41 and the rear shelf portion 42 have an engagement receiving portion 48 located on the inner side in the left-right direction with respect to the guide portion 47. The engagement receiving portion 48 has a shape in which the rear shelf portion 42 is recessed toward the rear outer side. The engagement receiving portion 48 accommodates the engagement protrusion 6 of the lid body 4 to be described later when the lid body 4 is opened.

2組の蝶着ピン51のうち第1の凹状部12と係合する一対の蝶着ピン51は、本体3からの蓋体4の抜け出し防止機能を発揮する。また、2組の蝶着ピン51のうち第2の凹状部22と係合する一対の蝶着ピン51は、本体3に蓋体4を簡易ロックする機能を発揮する。
蝶着ピン51は、上枠31の左右の内側面3aから、それぞれ基準軸Jに沿って突出して形成する。蝶着ピン51は、上枠31の側棚部43と後棚部42との間の間隙60に位置して本体3の開口部7に臨んで形成する。2組の一対の蝶着ピン51は、互いに向かい合っている。蝶着ピン51は、例えば、それぞれの側棚部43を正面に見るときに左右対称の形状で形成する。
The pair of hinge pins 51 that engage with the first concave portion 12 of the two sets of hinge pins 51 exerts a function of preventing the lid body 4 from coming out of the main body 3. In addition, the pair of hinge pins 51 that engage with the second concave portion 22 of the two sets of hinge pins 51 exhibit a function of simply locking the lid body 4 to the main body 3.
The hinge pin 51 is formed so as to protrude along the reference axis J from the left and right inner side surfaces 3 a of the upper frame 31. The hinge pin 51 is formed in the gap 60 between the side shelf 43 and the rear shelf 42 of the upper frame 31 and facing the opening 7 of the main body 3. The two pairs of butterfly pins 51 face each other. For example, the hinge pin 51 is formed in a symmetrical shape when each side shelf 43 is viewed in front.

蝶着ピン51と案内部47とは、図2に示すように平面視で、案内部47が前棚部41と後棚部42とを有する内周から突設し、蝶着ピン51が側棚部43を有する内周から突設して、互いに前後に近接対向している。蝶着ピン51は、後述するように、基準軸Jに沿って出没する蓋体4の第1の凹状部12と第2の凹状部22とのいずれに対しても進入と脱出が可能である。このため、筐体1は、蓋体4の取り付け方向を選択できる。   As shown in FIG. 2, the hinge pin 51 and the guide portion 47 are projected from the inner periphery having the front shelf portion 41 and the rear shelf portion 42 in a plan view, and the hinge pin 51 is on the side. It protrudes from the inner periphery which has the shelf part 43, and mutually adjoins front and back. As will be described later, the hinge pin 51 is capable of entering and exiting both the first concave portion 12 and the second concave portion 22 of the lid body 4 that appears and disappears along the reference axis J. . For this reason, the housing 1 can select the mounting direction of the lid 4.

図6、図7は、基準軸Jに沿って断面を取った筐体1の断面図であり、それぞれ蓋体4の第1の凹状部12に係合する蝶着ピン51を中心として拡大した図である。図6は、蓋体4の閉状態を示し、図7は、蓋体4の開状態を示す。
図6、図7に示すように、蝶着ピン51は、先端面55と上側斜面56と下側斜面57とを有する。上側斜面56は、蝶着ピン51の先端上部に位置する面であって、蝶着ピン51の根元側から先端側に向かって、斜め下方に傾斜する。下側斜面57は、蝶着ピン51の先端下部に位置する面であって、蝶着ピン51の根元側から先端側に向かって、斜め上方に傾斜する。上側斜面56および下側斜面57は、ともに、蝶着ピン51を先端側に向かって細める傾斜面である。上側斜面56は、下側斜面57と比較して傾斜角度が大きい。言い換えると、図6、図7に示すように、上側斜面56の水平方向に対する傾斜角度αは、下側斜面57の基準軸J(本実施形態において水平方向)に対する傾斜角度βよりも大きい。上側斜面56の傾斜角度αによって、蝶着ピン51は蓋体4の第1の凹状部12(又は第2の凹状部22)に円滑に挿入できる。
上側斜面56は、蓋体4を本体3に取り付ける際に、後段において説明する第1の係合部材(第1の係合部)71または第2の係合部材(第2の係合部)81と当接する面である。一方で、下側斜面57は、蓋体4を本体3から取り外す際に、第1の係合部材71または第2の係合部材81と当接する面である。
6 and 7 are cross-sectional views of the casing 1 taken along the reference axis J, and are enlarged around the hinge pin 51 that engages with the first concave portion 12 of the lid 4. FIG. 6 shows the closed state of the lid 4, and FIG. 7 shows the opened state of the lid 4.
As shown in FIGS. 6 and 7, the hinge pin 51 has a tip surface 55, an upper slope 56 and a lower slope 57. The upper slope 56 is a surface located at the upper end of the tip of the hinge pin 51 and is inclined obliquely downward from the base side of the hinge pin 51 toward the tip. The lower slope 57 is a surface located at the lower end of the tip of the hinge pin 51 and is inclined obliquely upward from the base side of the hinge pin 51 toward the tip. Both the upper slope 56 and the lower slope 57 are inclined surfaces that narrow the hinge pin 51 toward the distal end side. The upper slope 56 has a larger inclination angle than the lower slope 57. In other words, as shown in FIGS. 6 and 7, the inclination angle α of the upper slope 56 with respect to the horizontal direction is larger than the inclination angle β of the lower slope 57 with respect to the reference axis J (horizontal direction in the present embodiment). The hinge pin 51 can be smoothly inserted into the first concave portion 12 (or the second concave portion 22) of the lid body 4 by the inclination angle α of the upper inclined surface 56.
The upper slope 56 has a first engagement member (first engagement portion) 71 or a second engagement member (second engagement portion) which will be described later when the lid 4 is attached to the main body 3. 81 is a surface in contact with 81. On the other hand, the lower slope 57 is a surface that comes into contact with the first engagement member 71 or the second engagement member 81 when the lid 4 is removed from the main body 3.

次に、蓋体4について具体的に説明する。図4は、蓋体4を斜め下方から見た斜視図である。図5(a)は、蓋体4を斜め上方から見た斜視図であり、図5(b)は、蓋体4の第1の摺動構造体66近傍の拡大図であり、図5(c)は、蓋体4の第2の摺動構造体68近傍の拡大図である。蓋体4は、板部材65と、一対の第1の摺動構造体66と一対の第2の摺動構造体68とを有する。
<Cover body>
Next, the lid 4 will be specifically described. FIG. 4 is a perspective view of the lid 4 as viewed obliquely from below. FIG. 5A is a perspective view of the lid body 4 as viewed obliquely from above, and FIG. 5B is an enlarged view of the vicinity of the first sliding structure 66 of the lid body 4. c) is an enlarged view of the vicinity of the second sliding structure 68 of the lid 4. The lid 4 includes a plate member 65, a pair of first sliding structures 66, and a pair of second sliding structures 68.

図4に示すように、板部材65は、例えば左右方向に長手方向を有する矩形板状に形成する。板部材65は、例えば、合成樹脂で形成するが、強度が必要な場合は金属で形成する。板部材65の先端4a側には、左右方向中央部に蓋体4を上方回動する際に工具等を引っ掛けるための切欠凹部61を形成する。   As shown in FIG. 4, the plate member 65 is formed in a rectangular plate shape having a longitudinal direction in the left-right direction, for example. The plate member 65 is formed of, for example, synthetic resin, but is formed of metal when strength is required. On the front end 4a side of the plate member 65, a notch recess 61 for hooking a tool or the like when the cover body 4 is rotated upward is formed in the central portion in the left-right direction.

板部材65は、基端4b側に摺動面62を有する。摺動面62は、第1の摺動構造体66の後方に位置する。摺動面62は、板部材65の基端4b側の蓋体4を本体3に取り付けた状態で基準軸Jの周りに形成する。摺動面62は、基準軸Jを略中心とした略円弧状の湾曲面である。摺動面62の下端には、係合段部70を設ける。係合段部70は、左右方向長手状である。係合段部70は、蓋体4が基準軸Jを中心に回動するときに本体3の案内部47を摺動して蓋体4の回動を案内する。また、後述するように、係合段部70は、側棚部43の後方端部(又は前方端部)に位置する側棚端部44に当接して蓋体4の開状態を保持する(図8(b)参照)。   The plate member 65 has a sliding surface 62 on the base end 4b side. The sliding surface 62 is located behind the first sliding structure 66. The sliding surface 62 is formed around the reference axis J in a state where the lid 4 on the base end 4 b side of the plate member 65 is attached to the main body 3. The sliding surface 62 is a substantially arc-shaped curved surface with the reference axis J as the center. An engagement step 70 is provided at the lower end of the sliding surface 62. The engagement step portion 70 has a longitudinal shape in the left-right direction. The engaging step portion 70 slides on the guide portion 47 of the main body 3 to guide the rotation of the lid body 4 when the lid body 4 rotates about the reference axis J. Further, as will be described later, the engagement step portion 70 abuts on the side shelf end portion 44 located at the rear end portion (or front end portion) of the side shelf portion 43 and holds the open state of the lid body 4 ( (Refer FIG.8 (b)).

板部材65は、それぞれ第1の摺動構造体66又は第2の摺動構造体68を取り付けるための摺動構造体取付部65aを四隅にそれぞれ有する。
図6を基に、板部材65の摺動構造体取付部65aにおける第1の摺動構造体66の支持構造について説明する。なお、ここでは、第1の摺動構造体66について説明するが、第2の摺動構造体68も同様の方法で板部材65が支持する。
板部材65は、摺動構造体取付部65aにおいて、板部材65の下面から下方に延びる突出壁67を有する。また、板部材65は、摺動構造体取付部65aにおいて、スライドリブ64を有する。スライドリブ64は、板部材65の下面に向かって突出し、基準軸Jに沿って延びる。第1の係合部材71は、スライドリブ64が嵌る摺動溝74を形成する。これにより、第1の係合部材71は、基準軸J方向にのみ摺動して移動する。さらに、板部材65は、摺動構造体取付部65aにおいて、係止片63を有する。係止片63は、第1の摺動構造体66の左右方向外側の端部に位置する。係止片63は、第1の係合部材71の左右方向外側への移動範囲を制限する。
The plate member 65 has sliding structure attachment portions 65a for attaching the first sliding structure 66 or the second sliding structure 68, respectively, at the four corners.
Based on FIG. 6, the support structure of the first sliding structure 66 in the sliding structure mounting portion 65a of the plate member 65 will be described. Although the first sliding structure 66 will be described here, the plate member 65 also supports the second sliding structure 68 in the same manner.
The plate member 65 has a protruding wall 67 that extends downward from the lower surface of the plate member 65 in the sliding structure mounting portion 65a. Further, the plate member 65 has a slide rib 64 at the sliding structure mounting portion 65a. The slide rib 64 protrudes toward the lower surface of the plate member 65 and extends along the reference axis J. The first engaging member 71 forms a sliding groove 74 into which the slide rib 64 is fitted. Thereby, the first engagement member 71 slides and moves only in the reference axis J direction. Further, the plate member 65 has a locking piece 63 at the sliding structure mounting portion 65a. The locking piece 63 is located at the outer end in the left-right direction of the first sliding structure 66. The locking piece 63 limits the range of movement of the first engaging member 71 outward in the left-right direction.

図4に示すように、一対の第1の摺動構造体66は、板部材65の基端4bの左右両側にそれぞれ位置する。また、一対の第2の摺動構造体68は、先端4a側の左右両側にそれぞれ位置する。第1の摺動構造体66は、第1の係合部材(第1の係合部)71と弾性部材(付勢手段)72とカバー部材73とを有する。また、第2の摺動構造体68は、第2の係合部材(第2の係合部)81と弾性部材(付勢手段)72とカバー部材73とを有する。第1の摺動構造体66と第2の摺動構造体68を比較すると、第1の係合部材71と第2の係合部材81との形状が異なり、それ以外は概略同様の構造を有する。   As shown in FIG. 4, the pair of first sliding structures 66 are respectively located on the left and right sides of the base end 4 b of the plate member 65. In addition, the pair of second sliding structures 68 are located on both the left and right sides on the tip 4a side. The first sliding structure 66 includes a first engagement member (first engagement portion) 71, an elastic member (biasing means) 72, and a cover member 73. The second sliding structure 68 includes a second engagement member (second engagement portion) 81, an elastic member (biasing means) 72, and a cover member 73. When the first sliding structure 66 and the second sliding structure 68 are compared, the shapes of the first engaging member 71 and the second engaging member 81 are different. Have.

第1の係合部材71および第2の係合部材81は、それぞれ基準軸Jに沿って設け、基準軸J方向に沿って移動できる。弾性部材72は、第1の係合部材71および第2の係合部材81を基準軸Jに沿って外側に付勢する。カバー部材73は、基準軸Jの周りに位置して弾性部材72と第1の係合部材71または第2の係合部材81とを囲む。   The first engagement member 71 and the second engagement member 81 are provided along the reference axis J, respectively, and can move along the reference axis J direction. The elastic member 72 urges the first engagement member 71 and the second engagement member 81 outward along the reference axis J. The cover member 73 is located around the reference axis J and surrounds the elastic member 72 and the first engagement member 71 or the second engagement member 81.

一対の第1の係合部材71は、図4に示すように、蓋体4の基端4b側の左右方向両端部の同軸上に位置する。また、第1の係合部材71は、図5(b)に示すように、下方膨出形状を有する。第1の係合部材71には、蓋体4の左右方向の外側に向かって開口する第1の凹状部12を設ける。   As shown in FIG. 4, the pair of first engaging members 71 are located on the same axis at both ends in the left-right direction on the base end 4 b side of the lid body 4. Moreover, the 1st engaging member 71 has a downward bulging shape, as shown in FIG.5 (b). The first engaging member 71 is provided with a first concave portion 12 that opens toward the outside in the left-right direction of the lid 4.

第1の凹状部12は、蓋体4の回動軸側で本体3からの蓋体4の抜け出しを防止する。第1の係合部材71は、図5(a)に示すように、側面視で上側に水平な直径線を有する半円状の第1の凹状部12を有する。第1の凹状部12は、蓋体4の左右側面の外側方のみに開口して形成する。   The first concave portion 12 prevents the lid body 4 from coming out of the main body 3 on the rotating shaft side of the lid body 4. As shown in FIG. 5A, the first engagement member 71 has a semicircular first concave portion 12 having a horizontal diameter line on the upper side in a side view. The first concave portion 12 is formed to open only on the outer sides of the left and right side surfaces of the lid body 4.

第1の係合部材71は、第1の係合部材71を正面に見るとき、略左右対称の形状で、下面が前後方向に所定幅を有して下方へ凸の湾曲面状の湾曲面13に形成する。一対の第1の係合部材71の下側に位置する湾曲面13には、図4に示すように、基準軸Jと直交する方向に延びる係合突起6を設ける。係合突起6は、側面視略三角形状をなす。
係合突起6は、蓋体4が閉状態において後方に向かって延び、上枠31の係合受け部48(図1参照)が係合突起6を収容する。閉状態の蓋体4は、係合受け部48が係合突起6を収容するため、自動車の通過などで衝撃が加わる場合でも、基端4b側の跳ね上がりを防止できる。
また、係合突起6は、蓋体4が開状態において下方に向かって延びる。したがって、蓋体4を開状態とした際には、係合受け部48は、係合突起6を収容しない。このため、筐体1は、本体3から蓋体4を開状態で取り外しできる。
The first engagement member 71 has a substantially bilaterally symmetric shape when the first engagement member 71 is viewed from the front, and the lower surface has a predetermined width in the front-rear direction and is curved downward. 13 to form. As shown in FIG. 4, an engagement protrusion 6 extending in a direction perpendicular to the reference axis J is provided on the curved surface 13 positioned below the pair of first engagement members 71. The engagement protrusion 6 has a substantially triangular shape in side view.
The engagement protrusion 6 extends rearward when the lid 4 is closed, and the engagement receiving portion 48 (see FIG. 1) of the upper frame 31 accommodates the engagement protrusion 6. The lid 4 in the closed state can prevent the base end 4b from jumping up even when an impact is applied due to the passage of an automobile or the like because the engagement receiving portion 48 accommodates the engagement protrusion 6.
The engaging protrusion 6 extends downward when the lid 4 is in the open state. Therefore, when the lid 4 is in the open state, the engagement receiving portion 48 does not accommodate the engagement protrusion 6. For this reason, the housing 1 can be detached from the main body 3 with the lid 4 in an open state.

第1の係合部材71は、第1の凹状部12の外側から第1の凹状部12の縁部12aに向かって傾斜する取付抵抗低減面16を有する。取付抵抗低減面16は、閉状態の蓋体4の下側に位置している。本実施形態において、取付抵抗低減面16は、所定の曲率で湾曲した傾斜面であるが、直線的に面取りした傾斜面でもよい。   The first engaging member 71 has a mounting resistance reducing surface 16 that is inclined from the outside of the first concave portion 12 toward the edge portion 12 a of the first concave portion 12. The attachment resistance reduction surface 16 is located below the lid 4 in the closed state. In the present embodiment, the attachment resistance reduction surface 16 is an inclined surface curved with a predetermined curvature, but may be an inclined surface that is linearly chamfered.

また、第1の係合部材71は、第1の凹状部12の内周面に、取外抵抗低減面17と、抜け防止面20とを有する。取外抵抗低減面17と抜け防止面20とは、第1の凹状部12の内周面において基準軸Jの周方向に互いに隣り合っている。取外抵抗低減面17は、基準軸Jに対して、十分な角度で傾斜している。一方で、抜け防止面20は、基準軸Jに対して傾斜しないか、傾斜してもその傾斜角が僅かである。即ち、抜け防止面20は、基準軸Jに略平行する面である。
本実施形態において、取外抵抗低減面17は、所定の曲率で湾曲した傾斜面であるが、直線的に面取りした傾斜面であってもよい。
図6に示すように、閉状態の蓋体4において、第1の凹状部12は、抜け防止面20が上側を向く姿勢となる。また、図7に示すように、開状態の蓋体4において、第1の凹状部12は、取外抵抗低減面17が上側を向く姿勢となる。
The first engaging member 71 has a removal resistance reducing surface 17 and a removal preventing surface 20 on the inner peripheral surface of the first concave portion 12. The removal resistance reducing surface 17 and the removal preventing surface 20 are adjacent to each other in the circumferential direction of the reference axis J on the inner peripheral surface of the first concave portion 12. The removal resistance reduction surface 17 is inclined at a sufficient angle with respect to the reference axis J. On the other hand, the slip-off preventing surface 20 does not incline with respect to the reference axis J, or even if it inclines, the inclination angle is slight. That is, the omission prevention surface 20 is a surface substantially parallel to the reference axis J.
In the present embodiment, the removal resistance reducing surface 17 is an inclined surface curved with a predetermined curvature, but may be an inclined surface that is linearly chamfered.
As shown in FIG. 6, in the lid 4 in the closed state, the first concave portion 12 is in a posture in which the removal prevention surface 20 faces upward. As shown in FIG. 7, in the lid 4 in the open state, the first concave portion 12 is in a posture in which the removal resistance reducing surface 17 faces upward.

図6、図7に示すように、本体3に蓋体4を取り付けた状態において、第1の凹状部12は、蝶着ピン51を収容する。第1の凹状部12は、例えば蝶着ピン51の直径よりも十分に大きい直径を有している。また、蓋体4は、本体3の棚部41、42、43、43が支持する。したがって、蝶着ピン51は、蓋体4が閉状態のときも開状態のときも、第1の凹状部12の内周面に当接しない。すなわち、蝶着ピン51は、第1の凹状部12内を遊嵌する。このため、蓋体4を取り付けた状態において蝶着ピン51には、負担が加わらない。   As shown in FIGS. 6 and 7, the first concave portion 12 accommodates the hinge pin 51 in a state where the lid 4 is attached to the main body 3. The first concave portion 12 has a diameter sufficiently larger than the diameter of the hinge pin 51, for example. The lid 4 is supported by the shelf portions 41, 42, 43, 43 of the main body 3. Therefore, the butterfly pin 51 does not contact the inner peripheral surface of the first concave portion 12 when the lid 4 is in the closed state or in the open state. That is, the hinge pin 51 is loosely fitted in the first concave portion 12. For this reason, in the state which attached the cover body 4, the burden is not added to the hinge pin 51. FIG.

弾性部材72およびカバー部材73は、第1の摺動構造体66および第2の摺動構造体68に設ける。ここでは図6を基に第1の摺動構造体66におけるこれらの部材について説明するが、第2の摺動構造体68においても、同様である。
図6に示すように、本実施形態において、弾性部材72はコイルばねである。弾性部材72は、基準軸Jに沿う伸縮方向を有する。弾性部材72は、第1の係合部材71と板部材65の突出壁67との間で適度に圧縮した状態で介在する。第1の係合部材71には、第1の凹状部12と反対側の面に、弾性部材保持穴76を形成する。同様に、突出壁67は、第1の係合部材71と対向する面に弾性部材保持穴67aを有する。弾性部材保持穴76、67aは、基準軸Jに沿う方向に窪んで形成して弾性部材72が滑落しないように保持する。なお、弾性部材72は、付勢手段として使用できればその構成は限定しない。付勢手段としては、第1の係合部材71の一部を弾性変形可能な形状に形成しても良い。
カバー部材73は、第1の係合部材71と弾性部材72とを下方から覆う。カバー部材73は、図示しない係止片などによる係合やビスによって板部材65に固定する。カバー部材73は、第1の係合部材71を摺動可能に下方から保持する。
図4に示すように、カバー部材73には、基準軸Jに沿って、左右方向外側から内側に向かって延びる切欠部77を形成する。切欠部77の幅は、第1の係合部材71の係合突起6の摺動範囲よりも若干大きく形成する。切欠部77によって、第1の係合部材71は、基準軸Jに沿って移動するときに、係合突起6とカバー部材73とが干渉しない。また、切欠部77は、係合突起6を幅方向に挟むことで第1の係合部材71の移動をガイドする。さらに、切欠部77は、カバー部材73の内側に侵入する水分を排出すると共に、カバー部材73の内部の弾性部材72の状態を目視確認するときの点検窓の機能を有する。
The elastic member 72 and the cover member 73 are provided on the first sliding structure 66 and the second sliding structure 68. Here, these members in the first sliding structure 66 will be described based on FIG. 6, but the same applies to the second sliding structure 68.
As shown in FIG. 6, in the present embodiment, the elastic member 72 is a coil spring. The elastic member 72 has an expansion / contraction direction along the reference axis J. The elastic member 72 is interposed between the first engagement member 71 and the projecting wall 67 of the plate member 65 in a properly compressed state. An elastic member holding hole 76 is formed in the first engagement member 71 on the surface opposite to the first concave portion 12. Similarly, the protruding wall 67 has an elastic member holding hole 67 a on the surface facing the first engagement member 71. The elastic member holding holes 76 and 67a are formed so as to be recessed in the direction along the reference axis J, and hold the elastic member 72 so as not to slide down. The configuration of the elastic member 72 is not limited as long as it can be used as the urging means. As the biasing means, a part of the first engaging member 71 may be formed in a shape that can be elastically deformed.
The cover member 73 covers the first engaging member 71 and the elastic member 72 from below. The cover member 73 is fixed to the plate member 65 by engagement with a locking piece (not shown) or a screw. The cover member 73 holds the first engagement member 71 from below so as to be slidable.
As shown in FIG. 4, the cover member 73 is formed with a notch 77 extending along the reference axis J from the outside in the left-right direction toward the inside. The width of the notch 77 is formed to be slightly larger than the sliding range of the engagement protrusion 6 of the first engagement member 71. Due to the notch 77, the engagement protrusion 6 and the cover member 73 do not interfere with each other when the first engagement member 71 moves along the reference axis J. The notch 77 guides the movement of the first engaging member 71 by sandwiching the engaging protrusion 6 in the width direction. Further, the notch 77 discharges moisture entering the inside of the cover member 73 and has a function of an inspection window for visually confirming the state of the elastic member 72 inside the cover member 73.

一対の第2の係合部材81は、図4に示すように、蓋体4の先端4a側の左右方向両端部の同軸上に位置する。第2の係合部材81は、図5(c)に示すように、下方膨出形状を有する。第2の係合部材81には、蓋体4の左右方向の外側に向かって開口する第2の凹状部22を設ける。第2の係合部材81は、第2の係合部材81を正面に見るとき、略左右対称の形状で、下面が前後方向に所定幅を有して下方へ凸の湾曲面状の湾曲面23に形成する。   As shown in FIG. 4, the pair of second engaging members 81 are positioned on the same axis at both ends in the left-right direction on the front end 4 a side of the lid body 4. The second engaging member 81 has a downward bulging shape as shown in FIG. The second engaging member 81 is provided with a second concave portion 22 that opens toward the outside in the left-right direction of the lid body 4. When the second engagement member 81 is viewed from the front, the second engagement member 81 has a substantially bilaterally symmetric shape, and the lower surface has a predetermined width in the front-rear direction and is curved downward. 23.

第2の凹状部22は、蓋体4を簡易に浮上防止する簡易ロックである。第2の係合部材81は、図5(b)に示すように、側面視で上側に水平な直径線を有する半円状の第2の凹状部22を有する。第2の凹状部22は、蓋体4の左右側面の先端部に外側方のみに開口して形成する。
上述したように蓋体4は、第1の凹状部12が一対の2組の蝶着ピン51のうち何れか一方の組の蝶着ピンを収容して、本体3に取り付く。また、蓋体4は、基端4b側を中心に回転し開閉する。これに対して、第2の凹状部22は、蓋体4の閉状態で、他方の組の蝶着ピン51を収容し、蓋体4の開状態では、蝶着ピン51を収容しない。すなわち、第2の凹状部22は、開閉に伴って蝶着ピン51が出入りする(図9(a)〜(c)および図10(a)〜(c))。蓋体4は、第2の凹状部22によって、不用意に蓋体4が開状態になったり不用意に外れたりすることを防止できる。また作業者は、蓋体4の開閉時にクリック感を検知できる。
The second concave portion 22 is a simple lock that simply prevents the lid 4 from rising. As shown in FIG. 5B, the second engagement member 81 has a semicircular second concave portion 22 having a horizontal diameter line on the upper side in a side view. The second concave portion 22 is formed at the distal end portions on the left and right side surfaces of the lid 4 so as to open only outward.
As described above, the lid 4 is attached to the main body 3 with the first concave portion 12 accommodating either one of the pair of two hinge pins 51. The lid 4 rotates around the base end 4b side and opens and closes. On the other hand, the second concave portion 22 accommodates the other pair of butterfly pins 51 when the lid body 4 is closed, and does not accommodate the hinge pins 51 when the lid body 4 is open. That is, the hinge pin 51 enters and exits the second concave portion 22 in accordance with opening and closing (FIGS. 9A to 9C and FIGS. 10A to 10C). The lid 4 can prevent the lid 4 from being inadvertently opened or inadvertently removed by the second concave portion 22. The operator can detect a click feeling when the lid 4 is opened and closed.

図3(c)に示すように、第2の係合部材81は、第2の凹状部22の外側から縁部22aに向かって傾斜する閉抵抗低減面26と、第2の凹状部22内側から縁部22aに向かって傾斜する開抵抗低減面27とを有する。閉抵抗低減面26は、閉状態の蓋体4の下側に位置している。開抵抗低減面27は、閉状態の蓋体4において上側を向く面である。本実施形態において、閉抵抗低減面26および開抵抗低減面27は、所定の曲率で湾曲した傾斜面であるが、直線的に面取りした傾斜面でもよい。   As shown in FIG. 3C, the second engagement member 81 includes a closed resistance reduction surface 26 that is inclined from the outer side of the second concave portion 22 toward the edge portion 22a, and the inner side of the second concave portion 22. And an open resistance reducing surface 27 inclined toward the edge 22a. The closing resistance reducing surface 26 is located below the lid 4 in the closed state. The open resistance reduction surface 27 is a surface facing upward in the lid body 4 in the closed state. In the present embodiment, the closed resistance reducing surface 26 and the open resistance reducing surface 27 are inclined surfaces curved with a predetermined curvature, but may be inclined surfaces that are linearly chamfered.

図9(a)に示すように、本体3に蓋体4を取り付ける状態において、第2の凹状部22は、蝶着ピン51を収容する。第2の凹状部22は、例えば蝶着ピン51の直径よりも十分に大きい直径を有している。また、蓋体4は、本体3の棚部41、42、43、43が支持する。したがって、蝶着ピン51は、蓋体4が閉状態のときに第2の凹状部22の内周面に当接しない。すなわち、蝶着ピン51は、第2の凹状部22内を遊嵌する。このため、閉状態の蓋体4において蝶着ピン51には負担が加わらない。   As shown in FIG. 9A, the second concave portion 22 accommodates the butterfly pin 51 in a state where the lid body 4 is attached to the main body 3. The second concave portion 22 has a diameter sufficiently larger than the diameter of the hinge pin 51, for example. The lid 4 is supported by the shelf portions 41, 42, 43, 43 of the main body 3. Therefore, the butterfly pin 51 does not contact the inner peripheral surface of the second concave portion 22 when the lid 4 is in the closed state. That is, the butterfly pin 51 is loosely fitted in the second concave portion 22. For this reason, no burden is applied to the hinge pin 51 in the lid body 4 in the closed state.

<作用>
次に、筐体1の作用等を説明する。まず、蓋体4を本体3に対して回動する場合について、図8を参照して説明する。図8(a)、(b)は、基準軸Jと直交し、蓋体4の第1の係合部材71を横切る面で断面を取った断面図である。図8(a)、(b)は、それぞれ蝶着ピン51を中心として拡大した図である。図8(a)は、蓋体4の閉状態を示し、図8(b)は、蓋体4の開状態を示す。
<Action>
Next, the operation and the like of the housing 1 will be described. First, the case where the lid 4 is rotated with respect to the main body 3 will be described with reference to FIG. FIGS. 8A and 8B are cross-sectional views taken along a plane perpendicular to the reference axis J and crossing the first engagement member 71 of the lid body 4. FIGS. 8A and 8B are enlarged views centering on the hinge pin 51, respectively. FIG. 8A shows the closed state of the lid body 4, and FIG. 8B shows the open state of the lid body 4.

図8(a)に示す蓋体4が閉状態の筐体1は、本体3の前後左右4つの棚部41、42、43、43によって蓋体4を水平姿勢に支持する。またこのとき、蓋体4の第1の凹状部12の内部には、本体3の蝶着ピン51を収容している。第1の凹状部12は、蝶着ピン51を遊嵌可能な寸法で形成し、第1の凹状部12の内面は、蝶着ピン51と接触しない。つまり、蓋体4が閉状態のときの蝶着ピン51には、第1の凹状部12の内周面との当接による負荷が掛からない。また、図9(a)に示すように、蓋体4の第2の凹状部22内には、本体3の蝶着ピン51を挿入して蓋体4を簡易ロックしているが、第2の凹状部22と蝶着ピン51とは互いに接触していない。つまり、蓋体4が閉状態のとき蝶着ピン51には、当接による負荷が掛からない。   The housing 1 with the lid 4 shown in FIG. 8A in the closed state supports the lid 4 in a horizontal posture by the four shelf portions 41, 42, 43, 43 of the main body 3. At this time, the hinge pin 51 of the main body 3 is accommodated in the first concave portion 12 of the lid body 4. The first concave portion 12 is formed with a dimension that allows the hinge pin 51 to be loosely fitted, and the inner surface of the first concave portion 12 does not contact the hinge pin 51. That is, the load due to contact with the inner peripheral surface of the first concave portion 12 is not applied to the hinge pin 51 when the lid body 4 is in the closed state. Further, as shown in FIG. 9A, the lid 4 is simply locked by inserting the hinge pin 51 of the main body 3 into the second concave portion 22 of the lid 4. The concave portion 22 and the butterfly pin 51 are not in contact with each other. That is, when the lid body 4 is in the closed state, the hinge pin 51 is not subjected to a load due to contact.

閉状態(図8(a)参照)から蓋体4を開方向に回動すると、蓋体4の摺動面62が、本体3の案内部47上を摺動して、開状態(図8(b)参照)となる。開状態の蓋体4は、摺動面62の下端に位置する係合段部70が、側棚部43の後方端部に位置する側棚端部44に当接する。即ち、閉状態から開状態に移行する際に、案内部47は、蓋体4の係合段部70を側棚部43の側棚端部44まで案内する。
閉状態から開状態の移行において、第1の凹状部12が蝶着ピン51を遊嵌可能な寸法であるため、蝶着ピン51と第1の凹状部12とは当接せずに、蝶着ピン51に負荷が掛からない。
また、蝶着ピン51の突出高さによっては、蝶着ピン51の先端面55が第1の凹状部12の奥行面に当接する場合がある。この場合には、第1の係合部材71が基準軸Jに沿って左右方向に移動するため、蝶着ピン51への負荷が軽減する。このように、蓋体4は、閉状態から開状態への移行においても、蝶着ピン51に掛かる負荷を低減できる。
When the lid body 4 is rotated in the opening direction from the closed state (see FIG. 8A), the sliding surface 62 of the lid body 4 slides on the guide portion 47 of the main body 3, and the open state (FIG. 8). (See (b)). In the lid 4 in the open state, the engagement step portion 70 located at the lower end of the sliding surface 62 abuts on the side shelf end portion 44 located at the rear end portion of the side shelf portion 43. That is, when shifting from the closed state to the open state, the guide portion 47 guides the engagement step portion 70 of the lid body 4 to the side shelf end portion 44 of the side shelf portion 43.
In the transition from the closed state to the open state, since the first concave portion 12 has a dimension that allows the hinge pin 51 to be loosely fitted, the butterfly pin 51 and the first concave portion 12 do not come into contact with each other. No load is applied to the contact pin 51.
Further, depending on the protruding height of the hinge pin 51, the tip surface 55 of the hinge pin 51 may come into contact with the depth surface of the first concave portion 12. In this case, since the first engagement member 71 moves in the left-right direction along the reference axis J, the load on the hinge pin 51 is reduced. Thus, the lid 4 can reduce the load applied to the hinge pin 51 even in the transition from the closed state to the open state.

図8(b)に示す開状態の蓋体4の係合段部70は、側棚部43の側棚端部44と当接し係合する。係合段部70と側棚端部44のとの係合は、蓋体4の開方向への回動角度を規制する。また、本体3の上面30の後方内方縁角部30aは、蓋体4の上面4cと当接して、蓋体4の開方向への回動角度を規制する。その結果、図8(b)に示すように、本体3は、蓋体4を、側棚端部44と後方内方縁角部30aとの2カ所で支持して、蓋体4の起立姿勢を維持する。
なお、この起立姿勢となった蓋体4の摺動面62は、側棚部43と案内部47との間の間隙60に入り込む。これにより、蓋体4は、安定して開状態を保持できる。
The engagement step portion 70 of the lid 4 in the open state shown in FIG. 8B contacts and engages with the side shelf end portion 44 of the side shelf portion 43. Engagement between the engagement step portion 70 and the side shelf end portion 44 regulates the rotation angle of the lid body 4 in the opening direction. Further, the rear inner edge corner portion 30 a of the upper surface 30 of the main body 3 is in contact with the upper surface 4 c of the lid body 4 to regulate the rotation angle of the lid body 4 in the opening direction. As a result, as shown in FIG. 8 (b), the main body 3 supports the lid body 4 at two locations, that is, the side shelf end portion 44 and the rear inner edge corner portion 30a. To maintain.
Note that the sliding surface 62 of the lid body 4 in the standing posture enters the gap 60 between the side shelf portion 43 and the guide portion 47. Thereby, the cover body 4 can hold | maintain an open state stably.

また、開状態の蓋体4において、第1の凹状部12の内部には、本体3の蝶着ピン51を収容している。第1の凹状部12は、蓋体4が開状態においても蝶着ピン51を遊嵌可能な寸法で形成し、第1の凹状部12の内面は蝶着ピン51と接触しない。つまり、蓋体4が閉状態のときの蝶着ピン51には、第1の凹状部12の内周面との当接による負荷が掛からない。
このように、蓋体4の開状態時および閉状態時のいずれにおいても、第1の凹状部12の収容する蝶着ピン51は遊嵌状態である。これにより、蝶着ピン51には負荷が掛かり難く、蝶着ピン51のクリープの発生を抑制できる。また、第1の凹状部12と蝶着ピン51とは、蓋体4の回動時においてもほとんど非接触であり回動時の蝶着ピン51の負傷も抑制できる。
Further, in the lid 4 in the open state, the hinge pin 51 of the main body 3 is accommodated inside the first concave portion 12. The first concave portion 12 is formed in such a size that the hinge pin 51 can be loosely fitted even when the lid 4 is in an open state, and the inner surface of the first concave portion 12 does not contact the hinge pin 51. That is, the load due to contact with the inner peripheral surface of the first concave portion 12 is not applied to the hinge pin 51 when the lid body 4 is in the closed state.
Thus, the hinge pin 51 accommodated in the first concave portion 12 is in a loose-fitting state in both the open state and the closed state of the lid body 4. As a result, it is difficult to apply a load to the hinge pin 51, and the occurrence of creep of the hinge pin 51 can be suppressed. Further, the first concave portion 12 and the hinge pin 51 are almost in contact with each other even when the lid body 4 is rotated, and the injury of the hinge pin 51 during the rotation can be suppressed.

また、本体3の使用による経年変形があって蝶着ピン51が第1の凹状部12に接触する場合でも、第1の係合部材71には摺動ガタがあるため、蝶着ピン51に掛かる負荷を減少できる。なお、蓋体4を図8(a)の閉状態から図8(b)の開状態まで回動する際或いはその開状態からその閉状態まで回動する際の回動角度θは、例えば110度(略110度を含む)である。   Even when there is aged deformation due to the use of the main body 3 and the butterfly pin 51 comes into contact with the first concave portion 12, the first engaging member 71 has sliding backlash. The applied load can be reduced. When the lid body 4 is rotated from the closed state in FIG. 8A to the open state in FIG. 8B or when the lid body 4 is rotated from the open state to the closed state, the rotation angle θ is 110, for example. Degree (including approximately 110 degrees).

次いで、蓋体4の開閉に伴う、第2の凹状部22の作用について図9および図10を参照して説明する。
図9(a)〜(c)は、第2の凹状部22に蝶着ピン51を収容した状態の断面図である。
図9(a)〜(c)は、蓋体4の閉状態から開状態に移行する際の状態を示す。また、図10(a)〜(c)は、蓋体4の開状態から閉状態に移行する際の状態を示す。
Next, the operation of the second concave portion 22 accompanying opening and closing of the lid body 4 will be described with reference to FIGS. 9 and 10.
FIGS. 9A to 9C are cross-sectional views showing a state in which the hinge pin 51 is accommodated in the second concave portion 22.
9A to 9C show states when the lid 4 is shifted from the closed state to the open state. FIGS. 10A to 10C show states when the lid body 4 shifts from the open state to the closed state.

作業者は、蓋体4の先端4a側を持ち上げることで蓋体4を開くことができる。
図9(a)、(b)に示すように、閉状態から開状態に移行する際に、第2の係合部材81が上方に移動する。
図9(b)に示すように、蓋体4の先端4aを上方に持ち上げる途中で、蓋体4の第2の係合部材81と蝶着ピン51とが当接する。より具体的には、第2の係合部材81の第2の凹状部22の内周面に設ける開抵抗低減面27と蝶着ピン51の下側斜面57とが当接する。開抵抗低減面27と下側斜面57とは、互いに同方向に傾いている。開抵抗低減面27と下側斜面57とが当接する状態で蓋体4がさらに持ち上がることにより、開抵抗低減面27と蝶着ピン51とは、円滑に滑り合って第2の係合部材81に内側に向かって移動する力を与える。これにより、第2の係合部材81は、弾性部材72の弾性力に抗して蓋体4の左右方向の内側へ移動して蝶着ピン51を第2の凹状部22の外側に案内する。
開抵抗低減面27と下側斜面57とは、第2の係合部材81を円滑に移動して蝶着ピン51に加わる負荷を低減する機能を果たす。なお、開抵抗低減面27と下側斜面57とをともに設けることが好ましいが、少なくとも開抵抗低減面27を設ければ、この機能を発揮できる。
The operator can open the lid 4 by lifting the tip 4 a side of the lid 4.
As shown in FIGS. 9A and 9B, the second engagement member 81 moves upward when shifting from the closed state to the open state.
As shown in FIG. 9B, the second engaging member 81 of the lid 4 and the butterfly pin 51 abut on the way of lifting the tip 4 a of the lid 4 upward. More specifically, the open resistance reduction surface 27 provided on the inner peripheral surface of the second concave portion 22 of the second engagement member 81 and the lower slope 57 of the hinge pin 51 abut. The open resistance reducing surface 27 and the lower slope 57 are inclined in the same direction. When the lid 4 is further lifted in a state where the open resistance reducing surface 27 and the lower slope 57 are in contact with each other, the open resistance reducing surface 27 and the butterfly pin 51 are smoothly slid to each other and the second engaging member 81 is engaged. Gives the force to move inward. Accordingly, the second engagement member 81 moves inward in the left-right direction of the lid body 4 against the elastic force of the elastic member 72 and guides the hinge pin 51 to the outside of the second concave portion 22. .
The open resistance reducing surface 27 and the lower slope 57 serve to smoothly move the second engagement member 81 and reduce the load applied to the hinge pin 51. Although it is preferable to provide both the open resistance reducing surface 27 and the lower slope 57, this function can be exhibited if at least the open resistance reducing surface 27 is provided.

図9(c)に示すように、さらに蓋体4の先端4aを上昇すると、第2の係合部材81と蝶着ピン51との当接が解除する。第2の係合部材81は、弾性部材72の弾性復元力により初期位置に復帰する。   As shown in FIG. 9C, when the tip 4a of the lid 4 is further raised, the contact between the second engaging member 81 and the hinge pin 51 is released. The second engagement member 81 returns to the initial position by the elastic restoring force of the elastic member 72.

作業者は、以上の手順を経て蓋体4を開くことができる。上述したように、作業者が蓋体4を開く際には、弾性部材72が弾性変形する。したがって、蓋体4を開く作業には、弾性部材72の弾性力に抗して蓋体4の先端4aを持ち上げ力を加える必要がある。このため、蓋体4は、簡易なロックをなした状態で閉じていることになる。すなわち、自動車等の通過などによる衝撃が加わった場合であっても、先端4a側の跳ね上がりを防止できる。また、筐体1は、蓋体4の簡易ロックに工具を用いる必要がない。   The operator can open the lid 4 through the above procedure. As described above, when the operator opens the lid 4, the elastic member 72 is elastically deformed. Therefore, in order to open the lid body 4, it is necessary to apply a lifting force to the tip end 4 a of the lid body 4 against the elastic force of the elastic member 72. For this reason, the lid 4 is closed with a simple lock. That is, even when an impact due to passage of an automobile or the like is applied, it is possible to prevent the tip 4a from jumping up. Further, the housing 1 does not need to use a tool for simple locking of the lid 4.

作業者は、蓋体4の先端4a側を下側に押し込むことで蓋体4を閉じることができる。
図10(a)、(b)に示すように、蓋体4が開状態から閉状態に移行する際に、第2の係合部材81は、下降して蝶着ピン51に近づく。図10(b)に示すように、蓋体4の先端4aの降下途中で、蓋体4の第2の係合部材81と蝶着ピン51とが当接する。より具体的には、蓋体4の先端4aの降下途中で、第2の係合部材81の下側に位置する閉抵抗低減面26と蝶着ピン51の上側斜面56とが当接する。閉抵抗低減面26と上側斜面56とは、互いに同方向に傾いている。閉抵抗低減面26と上側斜面56とが当接した状態で、蓋体4がさらに降下すると、閉抵抗低減面26と上側斜面56とは、円滑に滑り合って第2の係合部材81に内側に向かって移動する力を与える。これにより、第2の係合部材81は、弾性部材72の弾性力に抗して蓋体4の左右方向の内側へ移動して蝶着ピン51を第2の凹状部22の内側に案内する。このように、閉抵抗低減面26は、蝶着ピン51を第2の凹状部22の内部に案内する。
The operator can close the lid body 4 by pushing the front end 4a side of the lid body 4 downward.
As shown in FIGS. 10A and 10B, when the lid body 4 shifts from the open state to the closed state, the second engagement member 81 descends and approaches the hinge pin 51. As shown in FIG. 10B, the second engaging member 81 of the lid 4 and the butterfly pin 51 come into contact with each other while the tip 4a of the lid 4 is being lowered. More specifically, the closing resistance reducing surface 26 located below the second engagement member 81 and the upper inclined surface 56 of the butterfly pin 51 come into contact with each other while the front end 4 a of the lid 4 is being lowered. The closing resistance reducing surface 26 and the upper inclined surface 56 are inclined in the same direction. When the lid 4 is further lowered in a state where the closing resistance reducing surface 26 and the upper slope 56 are in contact with each other, the closing resistance reducing surface 26 and the upper slope 56 are smoothly slid against each other to the second engagement member 81. Gives the force to move inward. Accordingly, the second engagement member 81 moves inward in the left-right direction of the lid body 4 against the elastic force of the elastic member 72 and guides the hinge pin 51 to the inside of the second concave portion 22. . Thus, the closed resistance reducing surface 26 guides the hinge pin 51 into the second concave portion 22.

図10(c)に示すように、さらに蓋体4を降下すると、第2の係合部材81と蝶着ピン51との当接が解除する。このとき、蓋体4を閉じる作業者には、当接の解除に伴うクリック感が伝わる。したがって、作業者は、暗所においても蓋体4が確実に閉じたことを容易に判別できる。   As shown in FIG. 10C, when the lid body 4 is further lowered, the contact between the second engaging member 81 and the hinge pin 51 is released. At this time, the operator who closes the lid body 4 receives a click feeling associated with the release of the contact. Therefore, the operator can easily determine that the lid 4 has been securely closed even in a dark place.

<蓋体の取り付け>
次いで、蓋体4を本体3に対して取り付ける場合について、図11を参照して説明する。
図11(a)〜(c)は、蓋体4を本体3に取り付ける手順を示す図である。
まず、図11(a)に示すように、作業者は、本体3に向けて蓋体4の先端4a側を手で持ちながら、例えば蓋体4を開方向に約10度から約90度傾ける状態として、さらに蓋体4をゆっくりと降下する。
<Attaching the lid>
Next, a case where the lid 4 is attached to the main body 3 will be described with reference to FIG.
FIGS. 11A to 11C are diagrams illustrating a procedure for attaching the lid 4 to the main body 3.
First, as shown in FIG. 11A, the operator tilts the lid body 4, for example, about 10 degrees to about 90 degrees in the opening direction while holding the front end 4 a side of the lid body 4 toward the main body 3 by hand. As a state, the lid 4 is further slowly lowered.

図11(b)に示すように、蓋体4の降下途中で、蓋体4の第1の係合部材71と本体3の蝶着ピン51とが当接する。より具体的には、蓋体4の降下途中で、第1の係合部材71の下側に位置する取付抵抗低減面16と蝶着ピン51の上側斜面56とが当接する。取付抵抗低減面16と上側斜面56とは、互いに同方向に傾いている。取付抵抗低減面16と上側斜面56とが当接した状態で、蓋体4がさらに降下すると、取付抵抗低減面16と蝶着ピン51とは、円滑に滑り合って第1の係合部材71が内側に移動する力を与える。これにより、第1の係合部材71は、弾性部材72の弾性力に抗して蓋体4の左右方向の内側へ移動して蝶着ピン51を第1の凹状部12に案内する。
取付抵抗低減面16と上側斜面56とは、第1の係合部材71を円滑に移動して蝶着ピン51に加わる負荷を低減する機能を果たす。なお、取付抵抗低減面16と上側斜面56とは、ともに設けることが好ましいが、少なくとも取付抵抗低減面16を設ければこの機能を発揮できる。
As shown in FIG. 11B, the first engaging member 71 of the lid body 4 and the butterfly pin 51 of the main body 3 come into contact with each other while the lid body 4 is being lowered. More specifically, during the lowering of the lid body 4, the attachment resistance reducing surface 16 located below the first engagement member 71 and the upper inclined surface 56 of the hinge pin 51 come into contact with each other. The attachment resistance reducing surface 16 and the upper inclined surface 56 are inclined in the same direction. When the lid 4 is further lowered while the attachment resistance reducing surface 16 and the upper slope 56 are in contact with each other, the attachment resistance reducing surface 16 and the hinge pin 51 are smoothly slid to each other and the first engaging member 71 is engaged. Gives the force to move inward. Accordingly, the first engaging member 71 moves inward in the left-right direction of the lid body 4 against the elastic force of the elastic member 72 and guides the hinge pin 51 to the first concave portion 12.
The attachment resistance reducing surface 16 and the upper slope 56 function to smoothly move the first engagement member 71 and reduce the load applied to the hinge pin 51. The attachment resistance reduction surface 16 and the upper slope 56 are preferably provided together, but this function can be exhibited if at least the attachment resistance reduction surface 16 is provided.

図11(c)に示すように、さらに蓋体4を降下すると、第1の係合部材71は、蝶着ピン51との当接を解除(取付抵抗低減面16による押圧の解除)する。第1の係合部材71は、弾性部材72の弾性復元力により初期位置に復帰して、蓋体4を本体3に取り付けできる。   As shown in FIG. 11C, when the lid body 4 is further lowered, the first engagement member 71 releases the contact with the hinge pin 51 (release of the pressing by the attachment resistance reducing surface 16). The first engaging member 71 can be returned to the initial position by the elastic restoring force of the elastic member 72, and the lid 4 can be attached to the main body 3.

以上の手順を経て、作業者は、蓋体4の第1の凹状部12に本体3の蝶着ピン51を挿入して蓋体4を本体3に取り付けできる。なお、作業者が蓋体4を開方向に傾けているため、蓋体4の係合突起6は、本体3の係合受け部48に干渉しない。このように、作業者は、蓋体4を降下するだけで、蓋体4を本体3に対して容易に取り付けできる。
なお、蓋体4に係合突起6を設けず、本体3に係合受け部48を設けない場合は、取り付けに際して、蓋体4を開方向に傾ける必要がない。したがって、この場合には、作業者は、蓋体4の姿勢を気にすることなく、蓋体4を本体3の開口部7に押し下げるのみで、蓋体4の第1の凹状部12に本体3の蝶着ピン51を挿入できる。
Through the above procedure, the operator can attach the lid 4 to the main body 3 by inserting the hinge pin 51 of the main body 3 into the first concave portion 12 of the lid 4. Since the operator tilts the lid body 4 in the opening direction, the engagement protrusion 6 of the lid body 4 does not interfere with the engagement receiving portion 48 of the main body 3. Thus, the operator can easily attach the lid body 4 to the main body 3 simply by lowering the lid body 4.
When the engagement protrusion 6 is not provided on the lid 4 and the engagement receiving portion 48 is not provided on the main body 3, it is not necessary to tilt the lid 4 in the opening direction when attaching. Therefore, in this case, the operator simply pushes the lid 4 down to the opening 7 of the main body 3 without worrying about the posture of the lid 4, and the main body is moved to the first concave portion 12 of the lid 4. 3 butterfly pins 51 can be inserted.

<蓋体の取外し>
次いで、蓋体4を本体3から取り外す場合について、図12を参照して説明する。図12(a)〜(c)は、蓋体4を本体3から取り外す手順を示す図である。
<Removing the lid>
Next, a case where the lid 4 is removed from the main body 3 will be described with reference to FIG. FIGS. 12A to 12C are diagrams illustrating a procedure for removing the lid 4 from the main body 3.

まず、図12(a)に示すように、蓋体4を開方向へ回動(例えば90度〜110度)して起立姿勢の開状態にする。さらに、この蓋体4を起立姿勢のまま上方に持ち上げる。この蓋体4の起立姿勢は、蓋体4の取外抵抗低減面17と蝶着ピン51との位置合わせを意味する。   First, as shown to Fig.12 (a), the cover body 4 is rotated to an opening direction (for example, 90 to 110 degree | times), and is made into the open state of a standing posture. Further, the lid body 4 is lifted upward while standing. The standing posture of the lid body 4 means the alignment between the removal resistance reducing surface 17 of the lid body 4 and the hinge pin 51.

図12(b)に示すように、蓋体4を上方に持ち上げる途中で、蓋体4の第1の係合部材71と本体3の蝶着ピン51とが当接する。より具体的には、第1の係合部材71の第1の凹状部12の内周面に設ける取外抵抗低減面17と蝶着ピン51の下側斜面57とが当接する。取外抵抗低減面17と下側斜面57とは互いに同方向に傾いている。取外抵抗低減面17と下側斜面57とが当接する状態で蓋体4がさらに持ち上がることにより、取外抵抗低減面17と蝶着ピン51とは、円滑に滑り合って第1の係合部材71に内側に移動する力を与える。これにより、第1の係合部材71は、弾性部材72の弾性力に抗して蓋体4の左右方向の内側へ移動して蝶着ピン51を第1の凹状部12の外側に案内する。
取外抵抗低減面17と下側斜面57とは、第1の係合部材71を円滑に移動して蝶着ピン51に加わる負荷を低減する機能を果たす。なお、取外抵抗低減面17と下側斜面57とをともに設けることが好ましいが、少なくとも取外抵抗低減面17を設ければ、この機能を発揮できる。
As shown in FIG. 12B, the first engaging member 71 of the lid body 4 and the butterfly pin 51 of the main body 3 abut on the way of lifting the lid body 4 upward. More specifically, the removal resistance reducing surface 17 provided on the inner peripheral surface of the first concave portion 12 of the first engaging member 71 and the lower inclined surface 57 of the butterfly pin 51 come into contact with each other. The removal resistance reducing surface 17 and the lower slope 57 are inclined in the same direction. When the lid 4 is further lifted in a state where the removal resistance reducing surface 17 and the lower slope 57 are in contact with each other, the removal resistance reducing surface 17 and the butterfly pin 51 are smoothly slid to each other for the first engagement. A force to move inward is given to the member 71. Accordingly, the first engagement member 71 moves inward in the left-right direction of the lid body 4 against the elastic force of the elastic member 72 and guides the hinge pin 51 to the outside of the first concave portion 12. .
The removal resistance reducing surface 17 and the lower inclined surface 57 perform a function of smoothly moving the first engagement member 71 and reducing a load applied to the hinge pin 51. Although it is preferable to provide both the removal resistance reducing surface 17 and the lower slope 57, this function can be exhibited if at least the removal resistance reducing surface 17 is provided.

ところで、図7に示すように、取外抵抗低減面17は、第1の凹状部12の内周面の周方向において、蓋体4の基端4b側にのみ形成する。即ち、取外抵抗低減面17は、蓋体4を開方向へ回動(例えば90度〜110度)して起立姿勢の開状態で、上側を向く部分にのみ形成する。また、第1の凹状部12の内周面の周方向において、取外抵抗低減面17以外の領域には、基準軸Jに対して、殆ど傾斜しない抜け防止面20を形成する。抜け防止面20は基準軸Jに対して傾斜しないため、蝶着ピン51による当接で第1の係合部材71が左右方向に移動できない。したがって、抜け防止面20が下側に位置する状態で蓋体4が上方に移動しようとしても、蝶着ピン51が抜け防止面20に係止して蓋体4が不用意に外れない。換言すると、蓋体4の第1の凹状部12の取外抵抗低減面17は、蓋体4を水平姿勢の閉状態から所定範囲内の回動角度で開方向に回動して持ち上げた場合にのみ、本体3の蝶着ピン51の下側斜面57と当接する。
このように、取外抵抗低減面17と抜け防止面20とは、蓋体4が、本体3に対して一定の角度で開状態にする場合にのみ、蓋体4の取り外しを許容する。
By the way, as shown in FIG. 7, the removal resistance reducing surface 17 is formed only on the base end 4 b side of the lid body 4 in the circumferential direction of the inner peripheral surface of the first concave portion 12. That is, the removal resistance reducing surface 17 is formed only in a portion facing the upper side in the open state of the standing posture by rotating the lid body 4 in the opening direction (for example, 90 degrees to 110 degrees). Further, in the circumferential direction of the inner peripheral surface of the first concave portion 12, a slip prevention surface 20 that hardly tilts with respect to the reference axis J is formed in a region other than the removal resistance reduction surface 17. Since the slip-off preventing surface 20 is not inclined with respect to the reference axis J, the first engaging member 71 cannot move in the left-right direction due to contact with the hinge pin 51. Therefore, even if the lid body 4 tries to move upward in a state where the removal prevention surface 20 is positioned on the lower side, the hinge pin 51 is locked to the removal prevention surface 20 so that the lid body 4 cannot be removed carelessly. In other words, the removal resistance reduction surface 17 of the first concave portion 12 of the lid body 4 lifts the lid body 4 by rotating it in the opening direction at a pivot angle within a predetermined range from the closed state of the horizontal posture. Only in contact with the lower inclined surface 57 of the hinge pin 51 of the main body 3.
As described above, the removal resistance reducing surface 17 and the removal preventing surface 20 permit the removal of the lid 4 only when the lid 4 is opened at a certain angle with respect to the main body 3.

図12(c)に示すように、さらに蓋体4を上昇すると、第1の係合部材71は、取外抵抗低減面17と蝶着ピン51との当接を解除(取外抵抗低減面17の押圧の解除)する。第1の係合部材71は、弾性部材72の弾性復元力により初期位置に復帰する。   As shown in FIG. 12C, when the lid body 4 is further raised, the first engagement member 71 releases the contact between the removal resistance reduction surface 17 and the hinge pin 51 (removal resistance reduction surface). 17 is released). The first engaging member 71 returns to the initial position by the elastic restoring force of the elastic member 72.

以上の手順を経て、作業者は、本体3の蝶着ピン51を蓋体4の第1の凹状部12内から挿出し、蓋体4を本体3から取り外しできる。このように、作業者は、蓋体4を起立姿勢にして上方に持ち上げるだけで蓋体4を本体3から容易に取り外しできる。   Through the above procedure, the operator can insert the hinge pin 51 of the main body 3 from the first concave portion 12 of the lid body 4 and remove the lid body 4 from the main body 3. In this way, the operator can easily remove the lid 4 from the main body 3 simply by raising the lid 4 in an upright position.

なお、この蓋体4の取り外し時には、蓋体4を図8(b)に示す開状態(回動角度θ=110度)まで回動する必要はない。例えば90度〜110度の範囲内の回動角度で、蓋体4を開方向へ回動すればよい。換言すると、蓋体4の第1の係合部材71の取外抵抗低減面17は、蓋体4を水平姿勢の閉状態から所定範囲内の回動角度で開方向に回動して持ち上げる場合にのみ、本体3の蝶着ピン51に当接する。   When removing the lid 4, it is not necessary to rotate the lid 4 to the open state (rotation angle θ = 110 degrees) shown in FIG. For example, the lid 4 may be rotated in the opening direction at a rotation angle in the range of 90 degrees to 110 degrees. In other words, the removal resistance reduction surface 17 of the first engaging member 71 of the lid 4 is lifted by rotating the lid 4 in the opening direction from the closed state of the horizontal posture at a rotation angle within a predetermined range. Only in contact with the hinge pin 51 of the main body 3.

<浮上防止>
次いで、大雨時の洪水等により、冠水が発生した場合の筐体1の状態について、図13を参照して説明する。冠水が発生し筐体1が水没すると蓋体4に浮力が生じる場合がある。ここでは、蓋体4に浮力が生じる場合の蓋体4の第1の係合部材71における外れ防止機能および第2の係合部材81における簡易ロック機能について説明する。
<Floating prevention>
Next, the state of the casing 1 when flooding occurs due to flooding during heavy rain will be described with reference to FIG. When the flooding occurs and the housing 1 is submerged, buoyancy may occur in the lid 4. Here, the detachment preventing function of the first engaging member 71 of the lid 4 and the simple locking function of the second engaging member 81 when buoyancy is generated in the lid 4 will be described.

図13(a)は、第1の係合部材71と蝶着ピン51の断面図であり、蓋体4に浮力が生じた場合の外れ防止機能を説明する図である。
筐体1が水没すると、蓋体4の簡易ロックである第2の凹状部22と蝶着ピン51との係合が外れて、開方向に回動(例えば90度未満)して、蓋体4の係合突起6が本体3の係合受け部48から離れて、蓋体4には浮上して第2の凹状部22と蝶着ピン51との係合を解除するような浮力が掛かる場合がある。この場合には、本体3の蝶着ピン51と蓋体4の抜け防止面20とが互いに当接する。第1の凹状部12の内周面の抜け防止面20は、取外抵抗低減面17に比べて曲率半径がかなり小さい。このため、筐体1は、本体3の蝶着ピン51と蓋体4の第1の凹状部12の抜け防止面20との当接によって、本体3から蓋体4の抜け出しを防止できる。
FIG. 13A is a cross-sectional view of the first engaging member 71 and the butterfly pin 51, and is a diagram for explaining a detachment preventing function when buoyancy is generated in the lid body 4.
When the housing 1 is submerged, the second concave portion 22 that is a simple lock of the lid body 4 and the butterfly pin 51 are disengaged and rotated in the opening direction (for example, less than 90 degrees), and the lid body 4 is separated from the engagement receiving portion 48 of the main body 3, and a buoyancy is applied to the lid body 4 so that the engagement between the second concave portion 22 and the butterfly pin 51 is released. There is a case. In this case, the butterfly pin 51 of the main body 3 and the removal preventing surface 20 of the lid body 4 come into contact with each other. The slip prevention surface 20 on the inner peripheral surface of the first concave portion 12 has a considerably smaller radius of curvature than the removal resistance reduction surface 17. For this reason, the housing 1 can prevent the lid body 4 from coming out of the main body 3 by the contact between the hinge pin 51 of the main body 3 and the slip-off preventing surface 20 of the first concave portion 12 of the lid body 4.

このように、本実施形態の筐体1によれば、本体3に対する蓋体4の取り付け作業および取り外し作業が容易であるとともに、本体3から蓋体4の不用意な外れを防止できる。
また、蓋体4の取付時には、取付抵抗低減面16と蝶着ピン51とが当接し、蓋体4の取外時には、取外抵抗低減面17と蝶着ピン51とが当接する。このため、蓋体4の取り付け作業および取り外し作業が容易である。
As described above, according to the housing 1 of the present embodiment, it is easy to attach and remove the lid body 4 to / from the main body 3 and to prevent the lid body 4 from being accidentally detached from the main body 3.
Further, when the lid body 4 is attached, the attachment resistance reduction surface 16 and the butterfly pin 51 abut, and when the lid body 4 is removed, the removal resistance reduction surface 17 and the hinge pin 51 abut. For this reason, the attachment operation | work of the cover body 4 and a removal operation | work are easy.

さらに、蓋体4の取外抵抗低減面17は、蓋体4を水平姿勢の閉状態から所定範囲内の回動角度で回動して持ち上げた場合にのみ、蝶着ピン51と当接する。このため、蓋体4の不用意な抜け出しを防止できる。
また、蓋体4の閉状態時および開状態時に第1の係合部材71と蝶着ピン51とが接触しても、第1の係合部材71が、左右方向に基準軸Jに沿って摺動するので互いに強く接触しない。このため、蓋体4の閉状態時および開状態時における本体3の蝶着ピン51の損傷を防止できる。
また、第1実施形態の筐体1は、第1の係合部材71を押圧する弾性部材72を有する。つまり、筐体1は、弾性部材72を筐体1の材質や設置場所に応じる押圧力を発揮する弾性部材72に変更できる。このため、筐体1は、蓋体4の不用意な抜け出しを防止できる。
Furthermore, the removal resistance reduction surface 17 of the lid 4 abuts on the hinge pin 51 only when the lid 4 is rotated and lifted at a rotation angle within a predetermined range from the closed state of the horizontal posture. For this reason, it is possible to prevent the lid 4 from being accidentally pulled out.
Even when the first engaging member 71 and the butterfly pin 51 come into contact with each other when the lid 4 is in the closed state and in the open state, the first engaging member 71 moves along the reference axis J in the left-right direction. Because they slide, they do not touch each other strongly. For this reason, damage to the hinge pin 51 of the main body 3 when the lid 4 is in the closed state and in the open state can be prevented.
The housing 1 of the first embodiment has an elastic member 72 that presses the first engagement member 71. That is, the housing 1 can change the elastic member 72 to an elastic member 72 that exerts a pressing force according to the material and installation location of the housing 1. For this reason, the housing 1 can prevent the lid 4 from being accidentally pulled out.

図13(b)は、第2の係合部材81と蝶着ピン51の断面図であり、蓋体4に浮力が生じた場合の簡易ロック機能を説明する図である。
蓋体4に浮力が掛かると、上述したように第1の係合部材71が蓋体4の基端4b側を係止しているために、蓋体4が開方向に回動しようとする力が生じる。本体3の蝶着ピン51と第2の係合部材81の開抵抗低減面27が互いに当接する。第2の係合部材81の開抵抗低減面27は傾斜しているために、上述の抜け防止面20と比較して、蝶着ピン51が抜け出しやすい。そのため、開抵抗低減面27の傾斜角度は、蓋体4の浮力に対して弾性部材72が撓んで第2の係合部材81が左右方向内側に移動するための応力を大きく設定することが好ましい。これにより、浮力による蓋体4の開きを抑制できる。また、蓋体4が開かないことで、蓋体4の係合突起6が本体3の係合受け部48から離れることがなく、蓋体4の離脱をさらに確実に防止できる。
FIG. 13B is a cross-sectional view of the second engaging member 81 and the butterfly pin 51, and is a diagram illustrating a simple lock function when buoyancy is generated in the lid body 4.
When buoyancy is applied to the lid body 4, the first engagement member 71 locks the base end 4 b side of the lid body 4 as described above, so that the lid body 4 tends to rotate in the opening direction. Power is generated. The hinge pin 51 of the main body 3 and the open resistance reducing surface 27 of the second engagement member 81 are in contact with each other. Since the open resistance reducing surface 27 of the second engagement member 81 is inclined, the hinge pin 51 is easily pulled out as compared with the above-described removal preventing surface 20. Therefore, the inclination angle of the open resistance reduction surface 27 is preferably set to a large stress for the elastic member 72 to bend with respect to the buoyancy of the lid body 4 and the second engagement member 81 to move inward in the left-right direction. . Thereby, the opening of the cover body 4 by buoyancy can be suppressed. Further, since the lid body 4 is not opened, the engagement protrusion 6 of the lid body 4 is not separated from the engagement receiving portion 48 of the main body 3, and the detachment of the lid body 4 can be further reliably prevented.

<効果>
以上に説明したように、本実施形態の筐体1によれば、第2の係合部材81の第2の凹状部22が、内側に移動して蝶着ピン51を収容する。第2の係合部材81は、蝶着ピン51と当接して弾性部材72に抗して移動する。これにより、簡易な構造による蓋体4の簡易ロックを実現する。
<Effect>
As described above, according to the housing 1 of the present embodiment, the second concave portion 22 of the second engagement member 81 moves inward and accommodates the hinge pin 51. The second engaging member 81 contacts the butterfly pin 51 and moves against the elastic member 72. Thereby, the simple lock | rock of the cover body 4 by a simple structure is implement | achieved.

また、本実施形態の筐体1によれば、筐体1の設置場所の状況に応じて、蓋体4の開閉方向を2つの基準軸Jうち何れか一方を選択することができる。したがって、本体3を地下に埋設した後に、本体3の周囲に新たな構造物を設置して蓋体4の開閉が困難となる場合にも、容易に蓋体4の開閉方向を変更できる。   Further, according to the housing 1 of the present embodiment, either one of the two reference axes J can be selected as the opening / closing direction of the lid 4 according to the situation of the installation location of the housing 1. Therefore, even when a new structure is installed around the main body 3 after the main body 3 is buried underground, the opening / closing direction of the lid 4 can be easily changed even when the opening / closing of the lid 4 becomes difficult.

また、本実施形態の筐体1によれば、本体3に対する蓋体4の取り付け作業および取り外し作業が容易であるとともに、本体3から蓋体4の不用意な外れを防止できる。
また、蓋体4の取付時には、取付抵抗低減面16と蝶着ピン51とが当接し、蓋体4の取外時には、取外抵抗低減面17と蝶着ピン51とが当接する。このため、蓋体4の取り付け作業および取り外し作業が容易である。
Moreover, according to the housing 1 of the present embodiment, the attaching operation and the removing operation of the lid body 4 with respect to the main body 3 are easy, and inadvertent removal of the lid body 4 from the main body 3 can be prevented.
Further, when the lid body 4 is attached, the attachment resistance reduction surface 16 and the butterfly pin 51 abut, and when the lid body 4 is removed, the removal resistance reduction surface 17 and the hinge pin 51 abut. For this reason, the attachment operation | work of the cover body 4 and a removal operation | work are easy.

さらに、蓋体4の取外抵抗低減面17は、蓋体4を水平姿勢の閉状態から所定範囲内の回動角度で回動して持ち上げた場合にのみ、蝶着ピン51と当接する。このため、蓋体4の不用意な抜け出しを防止できる。
また、蓋体4の閉状態時および開状態時に第1の係合部材71又は第2の係合部材81と蝶着ピン51とが接触しても、左右方向に基準軸Jに沿って第1の係合部材71又は第2の係合部材81が移動するので互いに強く接触しない。このため、蓋体4の閉状態時および開状態時における蝶着ピン51の損傷を防止できる。
Furthermore, the removal resistance reduction surface 17 of the lid 4 abuts on the hinge pin 51 only when the lid 4 is rotated and lifted at a rotation angle within a predetermined range from the closed state of the horizontal posture. For this reason, it is possible to prevent the lid 4 from being accidentally pulled out.
Even when the first engaging member 71 or the second engaging member 81 and the butterfly pin 51 come into contact with each other when the lid body 4 is in the closed state and in the open state, Since the first engagement member 71 or the second engagement member 81 moves, they do not come into strong contact with each other. For this reason, damage to the butterfly pin 51 when the lid 4 is in the closed state and in the open state can be prevented.

<第2実施形態>

軸部183aは、ねじ孔185にねじ込んで、ロックナット184により固定する。押圧力調整機構181は、調整ねじ183のねじ込みにより受け面182の位置を調整することで、コイルバネ172の初期圧縮力を調整できる。すなわち、押圧力調整機構181は、調整ねじ183をねじ込んだり緩めたりして弾性部材172の押圧力を調整できる。
第1実施形態および第2実施形態と同様に、第2の摺動構造体は、係合部材の形状を除き第1の摺動構造体166と概略同様の構成を有しているため、ここでの説明を省略する。なお、押圧力調整機構181を第2の摺動構造体に設ける場合は、簡易ロックの強さを調整できるので、筐体1の設置場所に応じて、簡易ロックの強さを簡易に調整できる。
The pressing force adjusting mechanism 181 includes an adjusting screw 183, a screw hole 185 provided in the protruding wall 169c, and a lock nut 184. The adjustment screw 183 has a shaft portion 183a and a head portion 183b. The outer diameter of the head 183b is larger than the spring diameter of the coil spring (elastic member, biasing means) 172. Further, the head 183b has a receiving surface 182 that receives the compressive force of the coil spring 172 on the side opposite to the shaft 183a. The receiving surface 182 holds, for example, a holding hole that is recessed toward the shaft portion 183a side so that the elastic member 172 does not slide down.
The shaft portion 183 a is screwed into the screw hole 185 and fixed by the lock nut 184. The pressing force adjusting mechanism 181 can adjust the initial compression force of the coil spring 172 by adjusting the position of the receiving surface 182 by screwing the adjusting screw 183. That is, the pressing force adjusting mechanism 181 can adjust the pressing force of the elastic member 172 by screwing or loosening the adjusting screw 183.
