〔開閉動作〕
次に、蓋を開閉する際の開閉装置１ａの動作を図３、図５、図６に基づいて説明する。 [Opening and closing operation]
Next, the operation of the opening / closing device 1a when opening and closing the lid will be described with reference to FIGS. 3, 5, and 6. FIG.

まず、図３に示すように、全開状態または片開き状態において開放されている開閉装置１ａでは、蓋側掛止部６が付勢部材５６，６５の付勢力により係合位置に保持されている。この係合位置では、蓋側掛止部６の爪部６２は、カバー部材７の内壁部７２の切り欠き７４から突出し、切り欠き７４に対向する案内凹部７３の側面に当接規制されている。   First, as shown in FIG. 3, in the opening / closing device 1 a opened in the fully open state or the single open state, the lid side latching portion 6 is held in the engaged position by the urging force of the urging members 56 and 65. . At this engagement position, the claw portion 62 of the lid side latching portion 6 protrudes from the notch 74 of the inner wall portion 72 of the cover member 7 and is abutted and regulated to the side surface of the guide recess 73 facing the notch 74. .

この状態から蓋３を箱本体２の上に重ねて開閉装置１ａを閉状態にする際、図５に示すように、箱側掛止部４の軸部材４１に蓋側掛止部６の爪部６２の円弧状の下面が当接し、蓋側掛止部６がこの当接による応力により内側へ一旦逃げ、爪部６２が軸部材４１の背面側を下方へ通過する。このとき、箱側掛止部４の軸部材４１は、案内凹部７３によって案内される。通過後は、蓋側掛止部６が付勢部材５６，６５の付勢力により外側方向（係合位置方向）に回動されて、爪部６２が軸部材４１と係合する（図６（ａ）参照）。   In this state, when the lid 3 is overlaid on the box body 2 to close the opening / closing device 1a, as shown in FIG. The arc-shaped lower surface of the portion 62 comes into contact, the lid side latching portion 6 temporarily escapes inward due to the stress caused by this contact, and the claw portion 62 passes through the back side of the shaft member 41 downward. At this time, the shaft member 41 of the box side latching portion 4 is guided by the guide recess 73. After the passage, the lid side latching portion 6 is rotated outward (engagement position direction) by the urging force of the urging members 56 and 65, and the claw portion 62 engages with the shaft member 41 (FIG. 6 ( a)).

図６（ａ）は、閉状態での操作部５および蓋側掛止部６を示している。この状態ではシール材３６が箱本体２の開口縁部２８に圧接している。また、第１箱側凹部２６はカバー部材７および操作部５によって覆われた状態となる。なお、図６（ａ）および図６（ｂ）では、理解の容易のために、操作部５と蓋側掛止部６とを一図面に示しており、また、箱側掛止部４は軸部材４１のみを示している。   FIG. 6A shows the operation portion 5 and the lid side latching portion 6 in the closed state. In this state, the sealing material 36 is in pressure contact with the opening edge portion 28 of the box body 2. Further, the first box-side recess 26 is covered with the cover member 7 and the operation unit 5. 6 (a) and 6 (b), the operation part 5 and the lid side latching part 6 are shown in one drawing for easy understanding, and the box side latching part 4 is Only the shaft member 41 is shown.

図６（ｂ）は、蓋３を箱本体２より外して全開状態とする場合、または、片開き状態とする際の過程を示している。この場合、２通りの開き方が選択可能である。１つは、側面操作部５９を操作して開く方法であり、もう１つは上面操作部５８を操作して開く方法である。   FIG. 6B shows a process when the lid 3 is removed from the box body 2 to be in a fully open state, or in a single-open state. In this case, two ways of opening can be selected. One is a method of opening by operating the side operation unit 59, and the other is a method of opening by operating the upper surface operation unit 58.

側面操作部５９を操作する場合、指で側面操作部５９を内側方向に押圧する。これにより、操作部５が回動し、側面操作部５９が付勢部材５６，６５の付勢力に抗して内側方向へ移動する。そして、この側面操作部５９の動きが伝達シャフト５７によって蓋側掛止部６に伝達され、蓋側掛止部６が側面操作部５９と同方向へすなわち内側方向へ回動する。これにより、軸部材４１に対する爪部６２の係合が解除される。この状態で、操作部５を上へ持ち上げると、操作部５と共に蓋３が上方に移動し、全開状態または片開き状態となる。   When the side operation unit 59 is operated, the side operation unit 59 is pressed inward with a finger. As a result, the operation unit 5 rotates and the side operation unit 59 moves inwardly against the urging force of the urging members 56 and 65. Then, the movement of the side operation portion 59 is transmitted to the lid side latching portion 6 by the transmission shaft 57, and the lid side latching portion 6 rotates in the same direction as the side operation portion 59, that is, inward. Thereby, the engagement of the claw portion 62 with the shaft member 41 is released. In this state, when the operation unit 5 is lifted upward, the lid 3 moves upward together with the operation unit 5 to be in a fully open state or a single open state.

また、上面操作部５８を操作する場合は、指を上面操作部５８と第２蓋側凹部３５の縁部３５ａとの間の隙間に挿入し、上面操作部５８に指を掛けて引き上げる。これにより、操作部５が回動し、上面操作部５８が付勢部材５６，６５の付勢力に抗して上方へ移動する。そして、この上面操作部５８の動きが伝達シャフト５７を介して蓋側掛止部６に伝達され、蓋側掛止部６が内側方向へ回動する。これにより、軸部材４１に対する爪部６２の係合が解除される。そして、この状態で、操作部５を上へ持ち上げると、操作部５と共に蓋３が上方に移動し、全開状態または片開き状態となる。   Further, when operating the upper surface operation unit 58, a finger is inserted into a gap between the upper surface operation unit 58 and the edge 35 a of the second lid side concave portion 35, and the upper surface operation unit 58 is put on the finger and pulled up. As a result, the operation unit 5 rotates and the upper surface operation unit 58 moves upward against the urging force of the urging members 56 and 65. And the movement of this upper surface operation part 58 is transmitted to the lid side latching part 6 via the transmission shaft 57, and the lid side latching part 6 rotates inside. Thereby, the engagement of the claw portion 62 with the shaft member 41 is released. In this state, when the operation unit 5 is lifted upward, the lid 3 moves upward together with the operation unit 5 to be in a fully open state or a single open state.

〔開閉動作〕
次に、蓋を開閉する際の開閉装置１ｂの動作を図１０および図１１に基づいて説明する。 [Opening and closing operation]
Next, the operation of the opening / closing device 1b when opening and closing the lid will be described with reference to FIGS.

まず、図１１（ａ）に示すように、全開状態または片開き状態で開放されている開閉装置１ｂでは、蓋側掛止部９が付勢部材８３の付勢力により係合位置に保持されている。この係合位置では、蓋側掛止部９の爪部９２がカバー部材１０の側壁部１３のうち、側部開口１１の両側部分（図９参照）の内面に当接規制されている。   First, as shown in FIG. 11A, in the opening / closing device 1b opened in a fully opened state or a single-opened state, the lid side latching portion 9 is held in the engaged position by the urging force of the urging member 83. Yes. At this engagement position, the claw portion 92 of the lid side latching portion 9 is regulated to contact the inner surface of both side portions (see FIG. 9) of the side opening 11 in the side wall portion 13 of the cover member 10.

この状態から蓋３を箱本体２の上に重ねて閉状態にする際、図１１（ｂ）に示すように、蓋側掛止部９が箱側掛止部４の軸部材４１に爪部９２の円弧状の下面が当接し、この当接による応力により内側へ一旦逃げ、爪部９２が軸部材４１の背面側に接しながら下側へ通過する。通過後は、蓋側掛止部９が付勢部材８３の付勢力により外側方向（係合位置方向）に回動されて、爪部９２が軸部材４１と係合する。   When the lid 3 is overlapped on the box body 2 from this state to be in the closed state, the lid side latching portion 9 is connected to the shaft member 41 of the box side latching portion 4 as shown in FIG. The arc-shaped lower surface of 92 is brought into contact with the inner surface, and once escaped inward due to the stress caused by the contact, the claw portion 92 passes downward while contacting the back side of the shaft member 41. After the passage, the lid side latching portion 9 is rotated outward (engagement position direction) by the urging force of the urging member 83, and the claw portion 92 is engaged with the shaft member 41.

図１０（ａ）及び（ｂ）の右図は閉状態での操作部８および蓋側掛止部９を示している。この状態では、側面操作部８４と第２箱側凹部２７との間の隙間は狭くなっており、側面操作部８４と第２箱側凹部２７との間には指を挿入不能となっている。また、側面操作部８４はカバー部材１０の側壁部１３の外面と概ね面一になっている。   The right diagrams of FIGS. 10A and 10B show the operation portion 8 and the lid side latching portion 9 in the closed state. In this state, the gap between the side operation portion 84 and the second box-side recess 27 is narrow, and a finger cannot be inserted between the side operation portion 84 and the second box-side recess 27. . The side operation portion 84 is substantially flush with the outer surface of the side wall portion 13 of the cover member 10.

図１０（ａ）及び（ｂ）の左図は、蓋３を箱本体２より外して全開状態とする場合、又は、蓋３を片開き状態とする際の過程を示している。この場合、２通りの開き方が選択可能である。１つは、側面操作部８４を操作して開く方法であり、もう１つは上面操作部８５を操作して開く方法である。   10A and 10B show a process when the lid 3 is removed from the box body 2 to be in a fully open state, or when the lid 3 is in a single open state. In this case, two ways of opening can be selected. One is a method of opening by operating the side operation unit 84, and the other is a method of opening by operating the upper surface operation unit 85.

側面操作部８４を操作する場合、指を側面操作部８４の凹部８４ａに差し込み、側面操作部８４を内側方向に押圧する。これにより、側面操作部８４が付勢部材８３の付勢力に抗して内側方向へ回動され、これと連動して、蓋側掛止部９が同方向へ回動される。これにより、軸部材４１に対する爪部９２の係合が解除される。そして、この状態で、側面操作部８４を上へ持ち上げると、側面操作部８４と共に蓋３が上方に移動し、全開状態または片開き状態となる。   When operating the side operation unit 84, a finger is inserted into the recess 84a of the side operation unit 84, and the side operation unit 84 is pressed inward. Thereby, the side operation part 84 is rotated inwardly against the urging force of the urging member 83, and in conjunction with this, the lid side latching part 9 is rotated in the same direction. Thereby, the engagement of the claw portion 92 with the shaft member 41 is released. In this state, when the side operation unit 84 is lifted upward, the lid 3 moves upward together with the side operation unit 84 to be in a fully open state or a single open state.

また、上面操作部８５を操作する場合は、指を上面操作部８５と第２蓋側凹部３８の縁部３８ａとの間の隙間に挿入し、上面操作部８５に指を掛けて引き上げる。これにより、上面操作部８５が付勢部材８３の付勢力に抗して上方向へ回動され、これと連動して、蓋側掛止部９が内側方向へ回動する。これにより、軸部材４１に対する爪部９２の係合が解除される。そして、この状態で、上面操作部８５を上へ持ち上げると、上面操作部８５と共に蓋３が上方に移動し、全開状態または片開き状態となる。   Further, when operating the upper surface operation unit 85, a finger is inserted into a gap between the upper surface operation unit 85 and the edge 38 a of the second lid side recess 38, and the upper surface operation unit 85 is pulled up with the finger. Thereby, the upper surface operation part 85 is rotated upward against the urging force of the urging member 83, and the lid side latching part 9 is rotated inward in conjunction with this. Thereby, the engagement of the claw portion 92 with the shaft member 41 is released. In this state, when the upper surface operation unit 85 is lifted upward, the lid 3 is moved upward together with the upper surface operation unit 85 to be in a fully open state or a single open state.

〔特徴〕
この開閉装置１ｂでも、第１実施形態に係る開閉装置１ａと同様に、上面操作部８５を上方に引き上げる操作と、側面操作部８４を内側方向に押圧する操作との２通りの操作により蓋３の開操作を行うことができる。蓋３の開操作が行い易くなっている。 〔Characteristic〕
Similarly to the opening / closing device 1a according to the first embodiment, the opening / closing device 1b also has a lid 3 that can be operated by two operations, that is, an operation of pulling up the upper surface operation unit 85 and an operation of pressing the side operation unit 84 inward. Can be opened. The opening operation of the lid 3 is easy to perform.

また、この開閉装置１ｂでは、上面操作部８５はカバー部材１０の上部開口１２から外部に露出しており、側面操作部８４はカバー部材１０の側部開口１１から外部に露出しており、連結部８６などの他の部分がカバー部材１０によって隠されている。また、上面操作部８５は蓋３の上面３ａと面一であり、側面操作部８４は蓋３の側面と面一である。このため、保冷箱１０１の外観上、隙間や凹凸が表れることが少なくなっており、保冷箱１０１の美観が向上している。   Further, in the opening / closing device 1b, the upper surface operation portion 85 is exposed to the outside from the upper opening 12 of the cover member 10, and the side operation portion 84 is exposed to the outside from the side opening 11 of the cover member 10, and is connected. Other portions such as the portion 86 are hidden by the cover member 10. Further, the upper surface operation unit 85 is flush with the upper surface 3 a of the lid 3, and the side operation unit 84 is flush with the side surface of the lid 3. For this reason, on the external appearance of the cool box 101, gaps and irregularities are less likely to appear, and the cool appearance of the cool box 101 is improved.

上記の実施形態では、蓋側掛止部６，９は、外側方向に付勢されることにより係合位置に保持されており、内側方向に移動することにより箱側掛止部４との係合が解除される。しかし、蓋側掛止部６，９の付勢方向は上記の方向に限られるものではなく、逆に、図１２に示す開閉装置１ｃのように、蓋側掛止部１５が内側方向に付勢されることにより係合位置に保持されてもよい。 <Other embodiments>
(A)
In the above-described embodiment, the lid side latching portions 6 and 9 are held in the engaged position by being urged outward, and are engaged with the box side latching portion 4 by moving inward. The match is released. However, the urging direction of the lid side latching portions 6 and 9 is not limited to the above-mentioned direction, and conversely, the lid side latching portion 15 is applied inward as in the opening / closing device 1c shown in FIG. It may be held in the engaged position by being biased.

この開閉装置１ｃでは、蓋側掛止部１５は、上部に伝達突起１６、下部に爪部１７、そして伝達突起１６と爪部１７との間に支持シャフト１８が通される貫通孔１９が設けられている。伝達突起１６は、蓋側掛止部１５から軸方向に突出して設けられた棒状の部分であり、操作部５の側壁部５２の内面に接触している。爪部１７は内側方向に突出して設けられており、付勢部材（図示せず）によって内側方向に付勢されることによって箱側掛止部４に係合する。蓋側掛止部１５は、支持シャフト１８を中心に回動可能に設けられている。   In the opening / closing device 1c, the lid-side latching portion 15 is provided with a transmission projection 16 at the upper portion, a claw portion 17 at the lower portion, and a through hole 19 through which the support shaft 18 is passed between the transmission projection 16 and the claw portion 17. It has been. The transmission protrusion 16 is a rod-like portion provided so as to protrude in the axial direction from the lid-side latching portion 15, and is in contact with the inner surface of the side wall portion 52 of the operation portion 5. The claw portion 17 is provided so as to protrude inwardly, and is engaged with the box side latching portion 4 by being biased inward by a biasing member (not shown). The lid side latching portion 15 is provided so as to be rotatable about the support shaft 18.

また、操作部５には、蓋側掛止部１５と操作部５とを強制的に連動させる強制連動部６７が設けられている。強制連動部６７は、蓋側掛止部１５の伝達突起１６の内側側面に係止している。   In addition, the operation unit 5 is provided with a forcible interlocking unit 67 that forcibly interlocks the lid side latching unit 15 and the operation unit 5. The forced interlocking portion 67 is locked to the inner side surface of the transmission protrusion 16 of the lid side latching portion 15.

操作部５の詳細および他の構成は上記の第１実施形態の開閉装置１ａと同様である。   The details and other configurations of the operation unit 5 are the same as those of the switchgear 1a of the first embodiment.

この開閉装置１ｃでは、図１２（ｂ）に示すように、側面操作部５９が押圧され、又は、上面操作部５８が引き上げられることにより、操作部５が回動すると、操作部５の内面によって伝達突起１６が内側方向に押されて移動する。伝達突起１６が内側方向に移動すると、蓋側掛止部１５が支持シャフト１８を中心に回動し、爪部１７が付勢部材の付勢力に抗して外側方向に移動して箱側掛止部４との係合が解除される。   In the opening / closing device 1c, as shown in FIG. 12B, when the operation unit 5 is rotated by pressing the side operation unit 59 or pulling up the upper operation unit 58, the inner surface of the operation unit 5 The transmission protrusion 16 is pushed inward to move. When the transmission projection 16 moves inward, the lid side latching portion 15 rotates about the support shaft 18 and the claw portion 17 moves outward against the urging force of the urging member to hang the box side. The engagement with the stop 4 is released.

このような開閉装置１ｃによっても、上記の開閉装置１ａ，１ｂと同様に、蓋３の開操作を行い易くすることができる。   Also with such an opening / closing device 1c, it is possible to facilitate the opening operation of the lid 3, as with the above-described opening / closing devices 1a, 1b.

また、強制連動部６７が伝達突起１６に係止していることにより、操作部５と蓋側掛止部１５とが必ず連動するようにされている。すなわち、図１２（ｂ）に示す状態から操作部５の側壁部５２が外側方向に回動した場合、伝達突起１６は外側方向に付勢されているために側壁部５２の移動に伴って外側方向に移動するはずであるが、強制連動部６７によっても外側方向に押圧されて移動する。このため、蓋側掛止部１５を操作部５の操作に確実に連動させて移動させることができる。これにより、操作部５が蓋３の表面と面一な状態に戻っているのに蓋側掛止部１５が係合状態に戻っていないというような誤作動状態の発生を防止することができる。   In addition, since the forced interlocking portion 67 is locked to the transmission protrusion 16, the operation portion 5 and the lid side latching portion 15 are always interlocked. That is, when the side wall 52 of the operation unit 5 is rotated outward from the state shown in FIG. 12B, the transmission protrusion 16 is urged outward, so that the outer side is moved along with the movement of the side wall 52. Although it should move in the direction, it is also pushed by the forced interlocking portion 67 in the outward direction. For this reason, the lid side latching part 15 can be reliably moved in conjunction with the operation of the operation part 5. As a result, it is possible to prevent the occurrence of a malfunctioning state in which the operation side 5 has returned to a state flush with the surface of the lid 3 but the lid side latching portion 15 has not returned to the engaged state. .

（Ｂ）
上記の他の実施形態（Ａ）では、強制連動部材６７によって誤作動状態の発生が防止されているが、操作部５と伝達突起１６とが互いに押圧し合う方向に付勢されることにより、誤作動状態の発生が防止されてもよい。 (B)
In the other embodiment (A) described above, the occurrence of a malfunctioning state is prevented by the forced interlocking member 67, but when the operation portion 5 and the transmission protrusion 16 are urged in a mutually pressing direction, Generation | occurrence | production of a malfunctioning state may be prevented.

例えば、図１３に示す開閉装置１ｄでは、操作部５は付勢部材６９によって内側方向に付勢されている。より具体的には、操作部５の側壁部５２が内側方向に付勢されており、上壁部５１は上方向に付勢されている。また、蓋側掛止部１５の爪部１７は付勢部材６８によって内側方向に付勢されることによって箱側掛止部４に係合する。この場合、伝達突起１６は外側方向、すなわち、操作部５の側壁部５２の内面に押圧される方向に付勢されている。このため、操作部５の側壁部５２と伝達突起１６とは互いに押圧し合う方向に付勢されている。   For example, in the opening / closing device 1 d shown in FIG. 13, the operation unit 5 is urged inward by the urging member 69. More specifically, the side wall 52 of the operation unit 5 is urged inward, and the upper wall 51 is urged upward. Further, the claw portion 17 of the lid side latching portion 15 is urged inward by the urging member 68 to engage with the box side latching portion 4. In this case, the transmission protrusion 16 is biased in the outward direction, that is, in the direction pressed against the inner surface of the side wall portion 52 of the operation portion 5. For this reason, the side wall part 52 and the transmission protrusion 16 of the operation part 5 are urged | biased in the direction which mutually presses.

このような開閉装置１ｄでは、操作部５の側壁部５２と伝達突起１６とが互いに押圧し合う方向に付勢されることにより、側壁部５２と伝達突起１６とが離れることが防止される。これにより、操作部５と蓋側掛止部１５とを確実に連動させることができ、誤作動状態の発生を防止することができる。   In such an opening / closing device 1d, the side wall 52 and the transmission protrusion 16 are urged in the direction in which they are pressed against each other, thereby preventing the side wall 52 and the transmission protrusion 16 from being separated. Thereby, the operation part 5 and the cover side latching part 15 can be made to interlock | cooperate reliably, and generation | occurrence | production of a malfunction state can be prevented.

なお、付勢部材６９による操作部５への付勢力を付勢部材６８の蓋側掛止部１５への付勢力よりも弱くすることによって、開閉装置１ｄが誤って開状態となってしまうことを防止することができる。   The opening / closing device 1d is erroneously opened by making the urging force of the urging member 69 to the operation unit 5 weaker than the urging force of the urging member 68 to the lid side latching portion 15. Can be prevented.

（Ｃ）
上記の実施形態におけるカバー部材７，１０の蓋３に占める部分の範囲は上記のものに限られるものではなく、より大きく、又は、より小さくすることができる。例えば、図１４に示すように、第１実施形態のカバー部材７より大きいカバー部材２０が設けられ、第２蓋側凹部３５がカバー部材２０に設けられてもよい。これにより、上面操作部５８の操作の際に指が差し込まれる隙間が上面操作部５８とカバー部材２０との間に形成される。 (C)
The range of the portion occupied by the cover 3 of the cover members 7 and 10 in the above embodiment is not limited to the above, but can be larger or smaller. For example, as shown in FIG. 14, the cover member 20 larger than the cover member 7 of the first embodiment may be provided, and the second lid side recess 35 may be provided in the cover member 20. Accordingly, a gap into which a finger is inserted when operating the upper surface operation unit 58 is formed between the upper surface operation unit 58 and the cover member 20.

In the above embodiment, the operation parts 5, 8 and the lid side latching parts 6, 9 are attached to the cover members 7, 10, but the operation parts 5, 8 and the lid side latching parts 6, 9 are What is necessary is just to be provided so that it may move with the lid | cover 3 in the case of opening / closing operation, and you may attach directly to the lid | cover 3.

また、第２実施形態において、カバー部材１０が設けられず、蓋３に側部開口１１や上部開口１２が設けられてもよい。   In the second embodiment, the cover member 10 may not be provided, and the side opening 11 and the upper opening 12 may be provided in the lid 3.

（Ｅ）
上記の実施形態では、上面操作部５８，８５と側面操作部５９，８４とが一体となって操作部５，８を構成しており、操作部５，８が第１支持シャフト５５や支持シャフト８２を中心に回動することによって、上面操作部５８，８５と側面操作部５９，８４とが連動する構成となっている。しかし、上面操作部と側面操作部とが連動する構成であれば、上面操作部と側面操作部とが別体に形成されてもよい。 (E)
In the above embodiment, the upper surface operation units 58 and 85 and the side surface operation units 59 and 84 are integrated to form the operation units 5 and 8, and the operation units 5 and 8 are the first support shaft 55 and the support shaft. By rotating around 82, the upper surface operation parts 58 and 85 and the side surface operation parts 59 and 84 are configured to work together. However, as long as the upper surface operation unit and the side surface operation unit are configured to be interlocked, the upper surface operation unit and the side surface operation unit may be formed separately.

（Ｆ）
上記の実施形態に係る開閉装置１ａ〜１ｄでは、付勢部材として、ねじりコイルバネが用いられているが、図１５に示す開閉装置１ｅように、圧縮コイルバネ４３が用いられてもよい。 (F)
In the switchgears 1a to 1d according to the above-described embodiments, the torsion coil spring is used as the biasing member, but a compression coil spring 43 may be used as the switchgear 1e shown in FIG.

この開閉装置１ｅでは、蓋側掛止部４４は、上端部に伝達シャフト４５ａが通される貫通孔４６ａ、下端に爪部４７、そして貫通孔４６ａと爪部４７との間に支持シャフト４５ｂが通される貫通孔４６ｂが設けられている。蓋側掛止部４４は、支持シャフト４５ｂを中心に回動可能に設けられている。貫通孔４６ａに通された伝達シャフト４５ａは、操作部４０に設けられた縦長の貫通孔（図示せず）に通されており、操作部４０の動きを蓋側掛止部４４に伝達する。爪部４７は内側方向に突出して設けられており、付勢部材としての圧縮コイルバネ４３によって内側方向に付勢されている。これにより、爪部４７は箱側掛止部４に係合する。また、蓋側掛止部４４の上端には、圧縮コイルバネ４３が取り付けられるバネ取付部４８が設けられている。バネ取付部４８は、内側方向に突出する突起であり、図１６に示すように、内部ケーシング５０の内壁部５０ａに設けられた凹部５０ｂと対向している。なお、図１６は、蓋側掛止部４４、および、蓋側掛止部４４を収容する内部ケーシング５０の上面図である。凹部５０ｂは、内部ケーシング５０の内壁部５０ａの上端に設けられており、圧縮コイルバネ４３を上方から挿入可能となっている。   In the opening / closing device 1e, the lid-side latching portion 44 has a through hole 46a through which the transmission shaft 45a passes, a claw portion 47 at the lower end, and a support shaft 45b between the through hole 46a and the claw portion 47. A through-hole 46b through which it passes is provided. The lid side latching portion 44 is provided so as to be rotatable about the support shaft 45b. The transmission shaft 45 a passed through the through hole 46 a is passed through a vertically long through hole (not shown) provided in the operation portion 40, and transmits the movement of the operation portion 40 to the lid side latching portion 44. The claw portion 47 protrudes inward and is urged inward by a compression coil spring 43 as an urging member. Thereby, the claw portion 47 engages with the box side latching portion 4. A spring attachment portion 48 to which the compression coil spring 43 is attached is provided at the upper end of the lid side latching portion 44. The spring mounting portion 48 is a protrusion that protrudes in the inward direction, and faces a recess 50b provided in the inner wall portion 50a of the inner casing 50, as shown in FIG. FIG. 16 is a top view of the lid side latching portion 44 and the inner casing 50 that houses the lid side latching portion 44. The recess 50b is provided at the upper end of the inner wall 50a of the inner casing 50, and the compression coil spring 43 can be inserted from above.

操作部４０は、内部ケーシング５０に支持シャフト４５ｃを介して回動可能に支持されている。操作部４０も蓋側掛止部４４と同様に圧縮コイルバネ７５によって付勢されている。この圧縮コイルバネ７５は、操作部４０を外側方向へ付勢している。なお、内部ケーシング５０および蓋側掛止部４４の上方はカバー部材１０によって閉じられており、カバー部材１０の上面と側面とにそれぞれ設けられた開口（図示せず）を通して操作部４０の側面操作部４０ａと上面操作部４０ｂとが外部に露出するようにされている。   The operation unit 40 is rotatably supported by the inner casing 50 via a support shaft 45c. The operation unit 40 is also urged by the compression coil spring 75 in the same manner as the lid side latching unit 44. The compression coil spring 75 urges the operation unit 40 outward. Note that the upper side of the inner casing 50 and the lid-side latching portion 44 is closed by the cover member 10, and the side surface operation of the operation portion 40 is performed through openings (not shown) provided on the upper surface and the side surface of the cover member 10, respectively. The part 40a and the upper surface operation part 40b are exposed to the outside.

この開閉装置１ｅでは、図１５（ｂ）に示すように、操作部４０の側面操作部４０ａが押圧され、又は、上面操作部４０ｂが引き上げられることにより、操作部４０が回動すると、伝達シャフト４５ａを介して操作部４０の動きが蓋側掛止部４４に伝達される。蓋側掛止部４４が、操作部４０の動きに連動して支持シャフト４５ｂを中心に回動すると、爪部４７が圧縮コイルバネ４３の付勢力に抗して外側方向に移動して箱側掛止部４との係合が解除される。   In the opening / closing device 1e, as shown in FIG. 15B, when the operation unit 40 is rotated by pressing the side operation unit 40a of the operation unit 40 or pulling up the upper operation unit 40b, the transmission shaft The movement of the operation unit 40 is transmitted to the lid side latching portion 44 through 45a. When the lid side latching portion 44 rotates around the support shaft 45b in conjunction with the movement of the operation portion 40, the claw portion 47 moves outward against the urging force of the compression coil spring 43, and the box side latching is performed. The engagement with the stop 4 is released.

このような開閉装置１ｅによっても、上記の開閉装置１ａ〜１ｄと同様に、蓋３の開操作を行い易くすることができる。また、ねじりコイルバネが用いられる場合と比べて、蓋側掛止部４４から伝わる力に対して効率よく反力を生じさせることができる。さらに、バネ取付部４８が蓋側掛止部４４の上端部に設けられ、凹部５０ｂが内部ケーシング５０の内壁部５０ａの上端に設けられているため、圧縮コイルバネ４３を凹部５０ｂおよびバネ取付部４８の上方から容易に取り付けることができる。   Also with such an opening / closing device 1e, the opening operation of the lid 3 can be facilitated in the same manner as the opening / closing devices 1a to 1d. Further, as compared with the case where a torsion coil spring is used, a reaction force can be efficiently generated with respect to the force transmitted from the lid side latching portion 44. Further, since the spring mounting portion 48 is provided at the upper end portion of the lid side latching portion 44 and the concave portion 50b is provided at the upper end of the inner wall portion 50a of the inner casing 50, the compression coil spring 43 is connected to the concave portion 50b and the spring mounting portion 48. It can be easily attached from above.

また、図１７に示すように、上記の第２実施形態に係る開閉装置１ｂにおいて、圧縮コイルバネ８９が付勢部材として設けられてもよい。   As shown in FIG. 17, in the opening / closing device 1b according to the second embodiment, a compression coil spring 89 may be provided as an urging member.

（Ｇ）
上記の他の実施形態（Ｆ）では、軸方向に同じ外径を有する圧縮コイルバネ４３が用いられているが、図１８に示すように、軸方向先端側ほど外径が小さくなり先細りの形状を有する円錐バネ４９が用いられてもよい。ここでは、円錐バネ４９は、蓋側掛止部９の箱側掛止部４と反対側、すなわち、蓋側掛止部９の内側に設けられている。 (G)
In the other embodiment (F) described above, the compression coil spring 43 having the same outer diameter in the axial direction is used. However, as shown in FIG. A conical spring 49 may be used. Here, the conical spring 49 is provided on the opposite side of the lid side latching portion 9 from the box side latching portion 4, that is, on the inside of the lid side latching portion 9.

この場合、円錐バネ４９は、上記のような円筒形の圧縮コイルバネ４３と比べて圧縮時に軸方向長さを短くすることができるため、蓋側掛止部９の箱側掛止部４と反対側の狭い空間であっても、容易に配置することができる。   In this case, the conical spring 49 can be shortened in the axial direction during compression as compared with the cylindrical compression coil spring 43 as described above, and thus the conical spring 49 is opposite to the box side hooking portion 4 of the lid side hooking portion 9. Even a narrow space on the side can be easily arranged.

（Ｈ）
上記の他の実施形態（Ｆ）では、付勢部材として圧縮コイルバネ４３が設けられているが、圧縮コイルバネに代えて引張コイルバネが設けられてもよい。 (H)
In the other embodiment (F), the compression coil spring 43 is provided as the urging member, but a tension coil spring may be provided instead of the compression coil spring.
