実施の形態１．
図１はこの発明の実施の形態１における回路遮断器の外部操作ハンドル装置の外観を示す斜視図、図２は図１の要部分解斜視図、図３は図１のドライブユニットの拡大平面図である。
図１及び２において、回路遮断器の外部操作ハンドル装置は、開閉可能に形成された扉１を有する箱形の配電盤あるいは分電気盤（図示しない）に装着されており、扉１の外側に回動可能に形成されたハンドル２が配設された操作ユニット３と、盤の内部に収納され回路遮断器４に装着されてこの回路遮断器４を開閉操作するドライブユニット５と、このドライブユニット５に接続部材６で固着され、扉１の開閉に応じてハンドル２に係脱し、扉１を閉じたときにハンドル２に係合しハンドル２の回動に連動して盤１の内部に収納された回路遮断器４をＯＮ、ＯＦＦ、またはリセット操作させるシャフト７とで構成されている。 Embodiment 1 FIG.
1 is a perspective view showing an external appearance of an external operation handle device for a circuit breaker according to Embodiment 1 of the present invention, FIG. 2 is an exploded perspective view of a main part of FIG. 1, and FIG. 3 is an enlarged plan view of a drive unit of FIG. is there.
1 and 2, the external operation handle device of the circuit breaker is mounted on a box-type switchboard or distribution board (not shown) having a door 1 formed to be openable and closable. An operation unit 3 having a handle 2 formed so as to be movable, a drive unit 5 which is housed inside the panel and is mounted on a circuit breaker 4 to open and close the circuit breaker 4, and is connected to the drive unit 5 A circuit that is fixedly attached to the member 6, is engaged / disengaged with the handle 2 according to the opening / closing of the door 1, is engaged with the handle 2 when the door 1 is closed, and is housed inside the panel 1 in conjunction with the rotation of the handle 2. It is comprised with the shaft 7 which makes the circuit breaker 4 ON, OFF, or reset operation.

なお、接続部材６は２枚の板状部材で形成されたおり、シャフト７をドライブユニット５の係合突起５ａに当接させ、シャフト７と係合突起５ａとを２枚の板状部材を挟持させた状態で締付ねじ８とナット９で固着される。
なお、２枚の板状部材は略Ｕ字状に連結された１枚の板状部材でも良い。
また、接続部材６にはシャフト７の軸方向に対して直角方向に所定の長さ延設された把持部６ａが設けられており、この把持部６ａは回路遮断器４を開閉操作するときに必要なトルクである、例えば、５Ｎ・ｍから１０Ｎ・ｍを手動によってシャフト７を容易に回動させることができる所定の長さ（例えば、図２において、Ｌを３０ｍｍから１５０ｍｍ）に設定される。
また、上記では把持部６ａをシャフト７の軸方向に対して片側方向に延設したが、対象的に両側方向に延設させても良く、この場合、片方向に延設した場合よりもシャフト７の回動操作時の必要トルクが減少するので回路遮断器４を開閉操作が容易となる。 The connecting member 6 is formed of two plate-like members. The shaft 7 is brought into contact with the engagement protrusion 5a of the drive unit 5, and the shaft 7 and the engagement protrusion 5a are sandwiched between the two plate-like members. In this state, it is fixed with the fastening screw 8 and the nut 9.
The two plate-like members may be one plate-like member connected in a substantially U shape.
Further, the connecting member 6 is provided with a gripping portion 6a extending a predetermined length in a direction perpendicular to the axial direction of the shaft 7, and this gripping portion 6a is used for opening and closing the circuit breaker 4. A required torque, for example, 5 N · m to 10 N · m is set to a predetermined length (for example, L is 30 mm to 150 mm in FIG. 2) by which the shaft 7 can be easily rotated manually. .
In the above description, the gripping portion 6a is extended in one direction with respect to the axial direction of the shaft 7. However, the gripping portion 6a may be extended in both directions. In this case, the shaft is longer than in the case of extending in one direction. Since the required torque at the time of the rotation operation 7 is reduced, the circuit breaker 4 can be easily opened and closed.

図３において、ドライブユニット５の表面にはＯＮ（オン位置）、ＯＦＦ（オフ位置）、ＴＲＩＰＰＥＤ（トリップ位置）及びＲＥＳＥＴ（リセット位置）を示す表示記号５ｂが施されており、回路遮断器４を操作したときに接続部材６の把持部６ａが表示記号５ｂ位置に合致し、回路遮断器４の開閉状態位置を示すように形成されている。   In FIG. 3, display symbols 5b indicating ON (ON position), OFF (OFF position), TRIPED (trip position) and RESET (reset position) are provided on the surface of the drive unit 5, and the circuit breaker 4 is operated. In this case, the gripping portion 6a of the connecting member 6 is formed so as to match the position of the display symbol 5b and indicate the open / closed position of the circuit breaker 4.

以上のように構成されたこの発明の実施の形態１における回路遮断器の外部操作ハンドル装置は、盤の扉１が閉じた状態において、操作ユニット３がシャフト７に係合した状態でハンドル２を回動させると、ドライブユニット５のドライブ機構（図示せず）により回路遮断器４が開閉される。この場合、上記のドライブ機構は、従来の機構と同様のものであり、例えば、シャフト７の回転運動を直線往復運動に変換して回路遮断器４の起倒形ハンドルをオン・オフ操作する機構を用いるが、この部分は発明の主要部ではないため説明を省略する。

The external operation handle device of the circuit breaker according to the first embodiment of the present invention configured as described above has the handle 2 in a state where the operation unit 3 is engaged with the shaft 7 in a state in which the panel door 1 is closed. When rotated, the circuit breaker 4 is opened and closed by a drive mechanism (not shown) of the drive unit 5. In this case, the above drive mechanism is the same as the conventional mechanism. For example, the mechanism that converts the rotational motion of the shaft 7 into a linear reciprocating motion to turn on and off the tilting handle of the circuit breaker 4. However, since this part is not a main part of the invention, description thereof is omitted.

盤の扉１が開いた状態においては、操作ユニット３と、盤内に設置された回路遮断器４に搭載されたドライブユニット５との係合が解除されるが、接続部材６に配設された把持部６ａを手などにより矢印Ａ方向（図３に示す）回動させることにより回路遮断器４の開閉操作を容易にできる。
また、回路遮断器４を開閉操作したときには接続部材６の把持部６ａが表示記号５ｂ位置に合致するので、回路遮断器４の状態判別が容易である。
なお、上記の実施例では接続部材６に把持部６ａを設け、回動させるようにしたが、図４に示すように操作レバー５ｃを固着させてドライブユニット５のドライブ機構（図示せず）を直接、操作することにより回路遮断器４の開閉操作を行っても良い。 When the panel door 1 is open, the operation unit 3 is disengaged from the drive unit 5 mounted on the circuit breaker 4 installed in the panel. The circuit breaker 4 can be easily opened and closed by rotating the gripping part 6a in the direction of arrow A (shown in FIG. 3) by hand or the like.
Further, when the circuit breaker 4 is opened and closed, the gripping portion 6a of the connecting member 6 matches the position of the display symbol 5b, so that the state of the circuit breaker 4 can be easily determined.
In the above embodiment, the connecting member 6 is provided with the gripping portion 6a and rotated. However, as shown in FIG. 4, the operation lever 5c is fixed to directly connect the drive mechanism (not shown) of the drive unit 5. The circuit breaker 4 may be opened and closed by operating.

図において、シャフト部１０は操作ユニット３のハンドル２に係合する係合軸１１、ドライブユニット５の係合突起５ａ（図２参照）に当接された状態で接続部材６に固着される基部１２、及びシャフト部１０を略Ｌ字状に折曲可能にする折曲部１３とにより形成され、折曲部１３はピン１３ａ（図７に示す）を有しており、係合軸１１の係合凹部１１ａに基部１２の係合凸部１２ａを嵌挿させた状態で、直線的に形成された係合軸１１の貫通孔１１ｂと基部１２の貫通孔１２ｂにピン１３ａを貫通させることで折曲可能にしている。
なお、基部１２とドライブユニット５の係合突起５ａとの接続部材６による固着構成については実施の形態１と同様である。

5 is a perspective view showing an external appearance of an external operation handle device for a circuit breaker according to Embodiment 2 of the present invention, FIG. 6 is a perspective view showing a state in which the shaft portion of FIG. 5 is bent, and FIG. It is an expansion disassembled perspective view which shows the structure of a shaft part.
In the figure, a shaft portion 10 is fixed to the connection member 6 in a state where the shaft portion 10 is in contact with an engagement shaft 11 engaged with the handle 2 of the operation unit 3 and an engagement protrusion 5 a (see FIG. 2) of the drive unit 5. And a bent portion 13 that enables the shaft portion 10 to be bent in a substantially L shape, and the bent portion 13 has a pin 13a (shown in FIG. 7). The pin 13a is folded by passing through the through hole 11b of the engaging shaft 11 and the through hole 12b of the base 12 formed linearly in a state in which the engaging convex portion 12a of the base 12 is inserted into the joint recess 11a. The song is made possible.
Note that the fixing configuration of the base 12 and the engagement protrusion 5a of the drive unit 5 by the connecting member 6 is the same as that of the first embodiment.
Further, configurations and operations other than those described above are the same as those in the first embodiment, and the same reference numerals are given, and descriptions thereof are omitted.

以上のように構成されたこの発明の実施の形態２における回路遮断器の外部操作ハンドル装置において、盤の扉１が開いた状態においては、操作ユニット３と、盤内に設置された回路遮断器４に搭載されたドライブユニット５との係合が解除され、シャフト部１０の係合軸１１を矢印Ｂ（図５に示す）に回動させて折り曲げ、係合軸１１を手などにより矢印Ｃ方向（図６に示す）回動させることにより回路遮断器４の開閉操作を容易にできる。   In the external operation handle device for a circuit breaker according to Embodiment 2 of the present invention configured as described above, when the panel door 1 is opened, the operation unit 3 and the circuit breaker installed in the panel 4 is disengaged from the drive unit 5 mounted on the shaft 4, the engagement shaft 11 of the shaft portion 10 is turned and bent in the direction of arrow B (shown in FIG. 5), and the engagement shaft 11 is moved in the direction of arrow C by hand. The circuit breaker 4 can be easily opened and closed by turning (shown in FIG. 6).

なお、ドライブユニット５の表面には上述した実施の形態１と同様に、ＯＮ（オン位置）、ＯＦＦ（オフ位置）、ＴＲＩＰＰＥＤ（トリップ位置）及びＲＥＳＥＴ（リセット位置）を示す表示記号５ｂが施されており（図３に示す）、回路遮断器４を操作したときに係合軸１１が表示記号５ｂ位置に合致し、回路遮断器４の状態判別が容易にできるものである。
また、本構成の場合、回路遮断器４の開閉操作を実施するか否かに係わらず、扉１が開いた状態において、係合軸１１を折り曲げておくとシャフト部１０の飛び出し量が減少するので、作業者などに対する安全性が高いという効果がある。 In addition, the display symbol 5b which shows ON (on position), OFF (off position), TRIPED (trip position), and RESET (reset position) is given to the surface of the drive unit 5 similarly to Embodiment 1 mentioned above. When the circuit breaker 4 is operated, the engagement shaft 11 matches the position of the indication symbol 5b, and the state of the circuit breaker 4 can be easily determined.
Further, in the case of this configuration, regardless of whether or not the circuit breaker 4 is opened and closed, if the engagement shaft 11 is bent when the door 1 is opened, the amount of protrusion of the shaft portion 10 is reduced. Therefore, there is an effect of high safety for workers.

実施の形態３．
図８は、この発明の実施の形態３における回路遮断器の外部操作ハンドル装置の側面図、図９は図８のドライブユニットを回路遮断器から外した状態を示す側面図、図１０は図８の遮断器接続部材の外観拡大斜視図、図１１は図８のユニット接続部材の外観拡大斜視図である。 Embodiment 3 FIG.
8 is a side view of an external operation handle device for a circuit breaker according to Embodiment 3 of the present invention, FIG. 9 is a side view showing a state in which the drive unit of FIG. 8 is removed from the circuit breaker, and FIG. FIG. 11 is an enlarged external perspective view of the unit connection member of FIG. 8.

図において、回路遮断器４には遮断器接続部材４ａが締付ねじ１４により固着され、ドライブユニット５にはユニット接続部材５ｄが締付ねじ１５により固着されている。
また、ユニット接続部材５ｄには軸受５ｄ１及び可動側係止部５ｄ２が配設され、遮断器接続部材４ａには軸受５ｄ１に嵌挿されてドライブユニット５を回動自在にさせる回動軸４ａ１及び可動側係止部５ｄ２が係合してドライブユニット５を回路遮断器４に装着された状態で係止させる固定側係止部４ａ２が配設されている。
なお、上記以外の構成および動作については実施の形態１と同様であり同一の番号を付し説明を省略する。 In the figure, a circuit breaker connecting member 4 a is fixed to the circuit breaker 4 by a fastening screw 14, and a unit connecting member 5 d is fixed to the drive unit 5 by a fastening screw 15.
The unit connection member 5d is provided with a bearing 5d1 and a movable side locking portion 5d2, and the circuit breaker connection member 4a is inserted into the bearing 5d1 to rotate the drive unit 5 and the movable shaft 4a1. A fixed-side locking portion 4a2 is provided that engages with the side locking portion 5d2 and locks the drive unit 5 in a state of being mounted on the circuit breaker 4.
Note that configurations and operations other than those described above are the same as those in the first embodiment, and the same reference numerals are given, and descriptions thereof are omitted.

以上のように構成されたこの発明の実施の形態３における回路遮断器の外部操作ハンドル装置は、盤の扉１が開いた状態において、ドライブユニット５を矢印Ｄ方向（図８に示す）へ回動させると可動側係止部５ｄ２と固定側係止部４ａ２との係合が解除され、ドライブユニット５は軸受５ｄ１を支点に回動して、回路遮断器４を直接開閉操作させる操作トッテ４ｂが露出する（図９に示す）ので、回路遮断器４の操作トッテ４ｂを矢印Ｅ方向に回動させることにより回路遮断器４の開閉操作を行うことができる。
また、ドライブユニット５は回動軸４ａ１と軸受５ｄ１が摺動して回動するので、回路遮断器４への着脱がスムーズである。
また、ドライブユニット５は、可動側係止部５ｄ２が固定側係止部４ａ２に係止されるので回路遮断器４に装着された状態で確実に保持される。 The external operation handle device for the circuit breaker according to the third embodiment of the present invention configured as described above rotates the drive unit 5 in the direction of arrow D (shown in FIG. 8) when the panel door 1 is open. As a result, the engagement between the movable side locking portion 5d2 and the fixed side locking portion 4a2 is released, and the drive unit 5 rotates around the bearing 5d1 to expose the operation tote 4b that directly opens and closes the circuit breaker 4. Therefore, the circuit breaker 4 can be opened and closed by rotating the operation tote 4b of the circuit breaker 4 in the direction of arrow E (see FIG. 9).
Further, since the drive shaft 5 rotates by sliding the rotation shaft 4a1 and the bearing 5d1, the drive unit 5 can be smoothly attached to and detached from the circuit breaker 4.
Further, the drive unit 5 is securely held in a state where it is mounted on the circuit breaker 4 because the movable side locking portion 5d2 is locked to the fixed side locking portion 4a2.
