以下に発明を実施するための形態を示す。本実施形態のクランプ式鎖錠装置１は図１に示すように箱本体５と扉６を備える電気機器収納用箱に組み込まれるものである。この鎖錠装置１は箱本体５の開口を覆う扉６の表面に取手部１３が位置するように固定部１８を介して取り付けられている。また、図２に示すように、扉６の裏面側には、機構部の構成要素である第一のクランプ部２１と第二のクランプ部３１が上下方向に並ぶように位置している。ここで、上下方向はクランプ式鎖錠装置１の長手方向を示し、前後方向はクランプ式鎖錠装置１の取手部１３の起伏方向を示している。   The form for implementing this invention is shown below. As shown in FIG. 1, the clamp type locking device 1 of the present embodiment is incorporated into an electric equipment storage box including a box body 5 and a door 6. The locking device 1 is attached via a fixing portion 18 so that the handle portion 13 is positioned on the surface of the door 6 covering the opening of the box body 5. Moreover, as shown in FIG. 2, the 1st clamp part 21 and the 2nd clamp part 31 which are the components of a mechanism part are located in the back surface side of the door 6 so that it may rank with an up-down direction. Here, the vertical direction indicates the longitudinal direction of the clamp-type locking device 1, and the front-back direction indicates the undulation direction of the handle portion 13 of the clamp-type locking device 1.

図３乃至図６に示すことから理解されるように、本実施形態のクランプ式鎖錠装置１は、ハンドル本体１２と、ハンドル本体１２に頭部が軸支される扉６の前面に位置される取手部１３と、上下方向に並ぶ一方のクランプ部である第一のクランプ部２１と他方のクランプ部である第二のクランプ部３１を取手部１３の起伏操作によって動作させる動作軸部保持部１４を有するハンドル１１からなるものである。また、図７に示すことから理解されるように、このクランプ式鎖錠装置１は、第一のクランプ部２１と、第二のクランプ部３１と、その何れか一方のクランプ部である第一クランプ部２１を動作させる第１リンク２２と、他方のクランプ部である第二クランプ部３１を動作させる第２リンク３２とを、取手部１３の回動中心となる第１軸１５の一方側に配置している。したがって、機構部を集約して配置することができ、開口部１６を小さくすることができるクランプ式鎖錠装置１とすることが可能となり、開口部１６を小さくできる。なお、図７に示すことから理解されるように、取手部１３の頭部を軸支する第１軸１５は、機構部を通過する開口部１６とは異なる位置に形成された凹部１２ａ内で軸支されている。そのため開口部１６を小さくできるため、開口部１６を覆うパッキン１９の形状がシンプルになり、パッキン１９の加工が容易となる。   As can be understood from FIGS. 3 to 6, the clamp type locking device 1 of the present embodiment is positioned on the front surface of the handle body 12 and the door 6 whose head is pivotally supported by the handle body 12. A handle portion 13, a first clamp portion 21 that is one clamp portion arranged in the vertical direction, and a second clamp portion 31 that is the other clamp portion are operated by raising and lowering the handle portion 13. It consists of a handle 11 having 14. In addition, as can be understood from FIG. 7, the clamp-type locking device 1 includes a first clamp portion 21, a second clamp portion 31, and one of the first clamp portions. The first link 22 that operates the clamp portion 21 and the second link 32 that operates the second clamp portion 31 that is the other clamp portion are arranged on one side of the first shaft 15 that is the rotation center of the handle portion 13. It is arranged. Therefore, it is possible to make the clamp-type locking device 1 capable of concentrating and arranging the mechanism portions and making the opening portion 16 small, and thus making the opening portion 16 small. As can be understood from FIG. 7, the first shaft 15 that pivotally supports the head of the handle portion 13 is in a recess 12 a formed at a position different from the opening 16 that passes through the mechanism portion. It is pivotally supported. Therefore, since the opening part 16 can be made small, the shape of the packing 19 which covers the opening part 16 becomes simple, and the processing of the packing 19 becomes easy.

本実施形態のクランプ部２１，３１には、ロッド棒６１が接続されている。ハンドル１１の取手部１３の起伏操作をすると、クランプ部２１，３１が互いに逆方向に回動すると共に、クランプ部２１，３１に接続されたロッド棒６１は、扉６に形成されたロッド棒支持金具６２にガイドされるように摺動する。このようにして移動したロッド棒６１が箱本体５に形成した係止片５１に係止されると、扉６をロックすることになる。なお、ロッド棒６１は必須のものではなく、例えば、クランプ部２１，３１が係止片５１に係止されることで扉６をロックするものであっても良い。   A rod rod 61 is connected to the clamp portions 21 and 31 of the present embodiment. When the handle portion 13 of the handle 11 is raised and lowered, the clamp portions 21 and 31 are rotated in opposite directions, and the rod rod 61 connected to the clamp portions 21 and 31 is supported by a rod rod formed on the door 6. Slide so as to be guided by the metal fitting 62. When the rod rod 61 moved in this way is locked by the locking piece 51 formed on the box body 5, the door 6 is locked. The rod bar 61 is not essential, and for example, the door 6 may be locked by the clamp portions 21 and 31 being locked to the locking piece 51.

すなわち、クランプ部２１、３１が閉じた状態では、ロッド棒６１が係止片５１に係止された状態、または、クランプ部２１、３１が係止片５１に係止された状態で、扉６が箱本体５に閉塞される。また、クランプ部２１、３１が開いた状態では、ロッド棒６１が係止片５１への係止を解除した状態やクランプ部２１、３１が係止片５１への係止を解除した状態で、扉６を箱本体５に対して回動可能な状態を示すものである。ここで、図３、図４に示すように取手部１３の閉じた状態から、図５、図６に示すように取手部１３を起伏操作した際には、第１のクランプ部２１は時計回りに開く方向に回動し、第２のクランプ部３１は反時計回りに開く方向に回動する。   That is, in the state where the clamp parts 21 and 31 are closed, the door 6 is in a state where the rod bar 61 is locked to the locking piece 51 or the clamp parts 21 and 31 are locked to the locking piece 51. Is closed by the box body 5. In the state where the clamp parts 21 and 31 are opened, the rod bar 61 is released from the engagement with the engagement piece 51 and the clamp parts 21 and 31 are released from the engagement with the engagement piece 51. A state in which the door 6 can be rotated with respect to the box body 5 is shown. Here, when the handle portion 13 is raised and lowered as shown in FIGS. 5 and 6 from the closed state of the handle portion 13 as shown in FIGS. 3 and 4, the first clamp portion 21 is rotated clockwise. The second clamp part 31 is rotated in the counterclockwise opening direction.

ここで本実施形態の第一のクランプ部２１周りについて詳しく説明する。本実施形態の鎖錠装置１には、ハンドル１１の取手部１３をハンドル本体１２に回動可能に接続する第１軸１５が設けられている。また、ハンドル１１と第１リンク２２とを回動可能に接続する第２軸２３、第１リンク２２と第一のクランプ部２１を回動可能に接続する第３軸２４が設けられている。また、第一のクランプ部２１をハンドル本体１２に回動可能に接続する第６軸２５を備えている。   Here, the vicinity of the first clamp portion 21 of the present embodiment will be described in detail. The locking device 1 of the present embodiment is provided with a first shaft 15 that rotatably connects the handle portion 13 of the handle 11 to the handle body 12. Further, a second shaft 23 that rotatably connects the handle 11 and the first link 22 and a third shaft 24 that rotatably connects the first link 22 and the first clamp portion 21 are provided. Moreover, the 6th axis | shaft 25 which connects the 1st clamp part 21 to the handle body 12 so that rotation is possible is provided.

図７から図１０までは、取手部１３が開いている状態から閉じるまでを順に示している。なお、第１軸１５と第３軸２４とを結ぶ中立線Ａと第２軸２３との関係を理解しやすくするため、この中立線Ａを破線で表している。また、取手部１３が閉じた状態から開いた状態への移行は、この逆の流れで行われる。   FIGS. 7 to 10 sequentially show from the state in which the handle portion 13 is open to the closing. In order to facilitate understanding of the relationship between the neutral line A connecting the first axis 15 and the third axis 24 and the second axis 23, the neutral line A is represented by a broken line. Further, the transition from the closed state of the handle 13 to the open state is performed in the reverse flow.

本実施形態においては、取手部１３の閉じ操作時に第２軸２３が第１軸１５と第３軸２４とを結ぶ中立線Ａを越えて移動し、図１０に示すように、第１軸１５と第３軸２４とを結ぶ中立線Ａを越えた状態においては、第一のクランプ部２１に反力を受けても、取手部１３が開く方向に動くことは無い。むしろ取手部１３がハンドル本体１２に密着するように荷重がかかる。これは、第一のクランプ部２１などが箱本体５の係止片５１に係止されたとき、係止片５１から受けた反力や箱本体５と扉６間に形成するパッキンの反力から第２軸２３に向けて与えられる力は、第１軸１５と第３軸２４とを結ぶ中立線Ａと第２軸２３との位置関係上、取手部１３が閉方向に動こうとするように作用するからである。また、この取手部１３が閉じた際に第２軸２３が、第１軸１５に対して第３軸２４よりも遠い位置に、詳しくは、第２軸２３は第１軸１５と第３軸２４より下方位置に形成している。   In the present embodiment, the second shaft 23 moves beyond the neutral line A connecting the first shaft 15 and the third shaft 24 during the closing operation of the handle portion 13, and as shown in FIG. In the state beyond the neutral line A connecting the first shaft 24 and the third shaft 24, the handle portion 13 does not move in the opening direction even if the first clamp portion 21 receives a reaction force. Rather, a load is applied so that the handle 13 is in close contact with the handle body 12. This is because the reaction force received from the locking piece 51 or the packing reaction force formed between the box body 5 and the door 6 when the first clamp portion 21 or the like is locked to the locking piece 51 of the box body 5. The force applied from the first to the second shaft 23 causes the handle portion 13 to move in the closing direction due to the positional relationship between the neutral axis A connecting the first shaft 15 and the third shaft 24 and the second shaft 23. This is because it works like this. Further, when the handle portion 13 is closed, the second shaft 23 is located farther than the third shaft 24 with respect to the first shaft 15. More specifically, the second shaft 23 is connected to the first shaft 15 and the third shaft. It is formed at a position below 24.

次に第二のクランプ部３１周りについて詳しく説明する。本実施形態の鎖錠装置１には、ハンドル１１と第２リンク３２とを回動可能に接続する第４軸３３と、第２リンク３２と他方のクランプ部を回動可能に接続する第５軸３４を備えている。   Next, the periphery of the second clamp part 31 will be described in detail. In the locking device 1 of the present embodiment, a fourth shaft 33 that rotatably connects the handle 11 and the second link 32, and a fifth link that rotatably connects the second link 32 and the other clamp portion. A shaft 34 is provided.

図１１から図１４までは、図７から図１０までと同様、取手部１３が開いている状態から閉じるまでを順に示している。しかし、図１１から図１４では第１軸１５と第５軸３４とを結ぶ中立線Ｂと第２軸２３との関係を理解しやすくするため、この中立線Ｂを破線で表している。   FIGS. 11 to 14 sequentially show from the open state to the close state of the handle portion 13, as in FIGS. 7 to 10. However, in FIGS. 11 to 14, the neutral line B is indicated by a broken line in order to facilitate understanding of the relationship between the neutral line B connecting the first axis 15 and the fifth axis 34 and the second axis 23.

取手部１３の閉じ操作時に、第４軸３３は、第１軸１５と第５軸３４とを結ぶ中立線Ｂを越えて移動する。図１４に示すように、第４軸３３が第１軸１５と第５軸３４とを結ぶ中立線Ｂを越えた状態においては、第二のクランプ部３１に反力を受けても取手部１３が開く方向に動くことは無い。この場合においても、第二のクランプ部３１に受ける反力が取手部１３を閉方向に動こうとするように作用する。この第４軸３３は、取手部１３を閉じた際に、第１軸１５と第５軸３４の間に位置している。   During the closing operation of the handle portion 13, the fourth shaft 33 moves beyond the neutral line B connecting the first shaft 15 and the fifth shaft 34. As shown in FIG. 14, in a state where the fourth shaft 33 exceeds the neutral line B connecting the first shaft 15 and the fifth shaft 34, the handle portion 13 is received even if the second clamp portion 31 receives a reaction force. Does not move in the opening direction. Even in this case, the reaction force received by the second clamp portion 31 acts to move the handle portion 13 in the closing direction. The fourth shaft 33 is located between the first shaft 15 and the fifth shaft 34 when the handle portion 13 is closed.

また、本実施形態の第４軸３３は取手部１３を閉じた際に、第２軸２３と前後位置に重なるような位置関係、詳しくは、第１リンク２２と第２リンク３２を回動可能に軸支する第２軸２３と第４軸３３を第１軸１５に対して同一半径の位置となり、取手部１３を回動したとき、第２軸２３と第４軸３３は同じ半径の軌跡を描く構造となっている。このため、平板状の取手部１３から背面方向に延びる動作軸部保持部１４や第１リンク２２や第２リンク３２などの開口部１６から前後に出入りする部分を集約することができ、開口部１６の大きさを抑制することが可能となる。なお、本実施形態の第二のクランプ部３１は第７軸３５により、ハンドル本体１２に対して回動可能に接続されている。また、第２軸と第４軸３３を第１軸１５に対して同一半径の位置にするため、取手部１３の起伏操作における動作距離が同じとなり、第一クランプ部２１と第二クランプ部３１の動きやロッド棒６１の可動領域を上下対称とすることが容易に行えるものである。   Further, the fourth shaft 33 of the present embodiment can rotate the first link 22 and the second link 32 in detail so that the second shaft 23 and the front and rear positions overlap when the handle portion 13 is closed. When the second shaft 23 and the fourth shaft 33 that are pivotally supported are positioned at the same radius with respect to the first shaft 15 and the handle portion 13 is rotated, the second shaft 23 and the fourth shaft 33 have a locus with the same radius. It has a structure to draw. For this reason, the part which goes in and out from the opening parts 16, such as the operation | movement shaft part holding | maintenance part 14, the 1st link 22, and the 2nd link 32 extended in the back direction from the flat plate-shaped handle part 13, can be collected. The size of 16 can be suppressed. Note that the second clamp portion 31 of the present embodiment is rotatably connected to the handle body 12 by a seventh shaft 35. Further, since the second shaft and the fourth shaft 33 are positioned at the same radius with respect to the first shaft 15, the operating distance in the raising / lowering operation of the handle portion 13 becomes the same, and the first clamp portion 21 and the second clamp portion 31. It is possible to easily make the movement of the rod rod 61 and the movable region of the rod rod 61 symmetrical in the vertical direction.

図１５に示すように、本実施形態においては、トグルバネ４１を備えている。このトグルバネ４１は、取手部１３を閉方向に移動させた際に、取手部１３が閉状態とするように付勢する。このため、不用意に扉６が開放されることを防ぐことができる。なお、トグルバネ４１は取手部１３を開方向に移動させた際に、取手部１３が開状態となるように付勢する。このため、取手部１３の起伏操作を行い易くなっている。   As shown in FIG. 15, in this embodiment, a toggle spring 41 is provided. This toggle spring 41 urges the handle 13 to be closed when the handle 13 is moved in the closing direction. For this reason, it is possible to prevent the door 6 from being opened carelessly. The toggle spring 41 urges the handle 13 to be in the open state when the handle 13 is moved in the opening direction. For this reason, it is easy to perform the raising / lowering operation of the handle part 13.

本実施形態では第一のクランプ部２１と第二のクランプ部３１は、リンク構造がそれぞれ独立しており、それぞれがクランプ部に掛かる反力に対して回動することを防止する構造となっている。また、動作軸部保持部１４や第１リンク２２や第２リンク３２を集約することでハンドル１１と各リンクの固定部分を小さくすることができ、ハンドル１１を短く形成することが可能となる。   In the present embodiment, the first clamp part 21 and the second clamp part 31 have a structure in which the link structure is independent of each other, and each of the first clamp part 21 and the second clamp part 31 has a structure that prevents rotation against a reaction force applied to the clamp part. Yes. Further, by consolidating the operation shaft holding portion 14, the first link 22, and the second link 32, the fixed portion between the handle 11 and each link can be reduced, and the handle 11 can be formed short.

以上、一つの実施形態を中心に説明してきたが、本発明は上記実施形態に限定されることはなく、各種の態様とすることが可能である。   As mentioned above, although it demonstrated centering on one embodiment, this invention is not limited to the said embodiment, It can be set as various aspects.
