Description

本発明は、配線用回路遮断器などを対象に、該回路遮断器に備えたハンドル装置，もしくは回路遮断器の外部付属装置として遮断器本体に取り付けて開閉操作する外部ハンドル装置に関する。   The present invention relates to a circuit breaker for wiring and the like, and to a handle device provided in the circuit breaker, or an external handle device that is attached to a breaker body as an external accessory device of the circuit breaker and is opened and closed.

頭記の配線用回路遮断器は主回路接点を開閉操作するハンドルを備えており、操作タイプ別にロッカー形ハンドル（起倒式），あるいはロータリー形ハンドルがある。また、回路遮断器の外部付属装置として、配電盤,制御盤などの盤内に配置した回路遮断器を盤外から手動で開閉操作する外部操作ハンドル装置が周知であり、その従来例を図５に示す（特許文献１参照）。
図５（ａ），（ｂ）において、１はロッカー形ハンドルを備えた回路遮断器、２は外部付属装置として回路遮断器１に組み付けた外部操作ハンドル装置、３は該ハンドル装置の基台、４は基台３の前面に設けたロータリー形のハンドル把手、５は把手４をＯＮないしＯＦＦ位置で鎖錠するように掛けた南京錠であり、ハンドルの把手４は基台３の前部側に形成した円筒状台部になる取付ベース３ａの凹部に配して基台３の裏面側に組み込んだ駆動アーム６にカム機構を介して連結し、図示のようにハンドル装置２を回路遮断器１に組み付け状態で前記駆動アーム６を回路遮断器１のロッカー形ハンドル１ａと連繋するようにしている。なお、把手４の回転操作範囲は、メカ的にＯＮ位置とＯＦＦ位置の間の範囲（９０°）に規制されている。 The circuit breaker for wiring mentioned above has a handle for opening and closing the main circuit contact, and there are a rocker type handle (tilting type) or a rotary type handle depending on the operation type. As an external accessory device for a circuit breaker, an external operation handle device for manually opening / closing a circuit breaker arranged in a panel such as a switchboard or a control panel from the outside of the panel is well known. This is shown (see Patent Document 1).
5 (a) and 5 (b), 1 is a circuit breaker provided with a rocker type handle, 2 is an external operation handle device assembled to the circuit breaker 1 as an external accessory device, 3 is a base of the handle device, Reference numeral 4 denotes a rotary handle handle provided on the front surface of the base 3, and 5 denotes a padlock for locking the handle 4 in an ON or OFF position, and the handle handle 4 is attached to the front side of the base 3. The handle device 2 is connected to a drive arm 6 which is arranged in a concave portion of the mounting base 3a which becomes the formed cylindrical base portion and is incorporated on the back side of the base 3 via a cam mechanism, and the handle device 2 is connected to the circuit breaker 1 as shown in the figure. In the assembled state, the drive arm 6 is connected to the rocker type handle 1 a of the circuit breaker 1. The rotation operation range of the handle 4 is mechanically restricted to a range (90 °) between the ON position and the OFF position.

かかる外部操作ハンドル装置２は、前記把手４を配電盤などの盤パネル７の前方に突き出して盤内に装備した回路遮断器１に取り付け、この状態で把手４を手動でＯＮ，ＯＦＦ位置に回すことにより駆動アーム６を介してロッカーハンドル１ａを駆動し、回路遮断器１の主回路接点を開閉する。また、回路遮断器１のハンドル１ａをＯＮ，ないしＯＦＦ位置に鎖錠する場合には、図示のように取付ベース３ａの円筒壁に開口したロック穴に南京錠５のアーム５ａを掛けて施錠し、ハンドルの把手４がＯＮからＯＦＦ位置、あるいは逆にＯＦＦからＯＮ位置に移動するのを阻止するようにしている。
また、前記ハンドル装置のロック機構として、把手の後部に引出し式のロックプレートを設け、ハンドルのロック位置で把手から引出した前記ロックプレートに南京錠を掛けて、ハンドルをＯＮないしＯＦＦ位置に鎖錠するようにした構成のものも公知である（例えば、特許文献２参照）。 Such an external operation handle device 2 projects the handle 4 forward of a panel panel 7 such as a switchboard and attaches it to the circuit breaker 1 installed in the panel, and in this state, manually turns the handle 4 to the ON / OFF position. As a result, the rocker handle 1a is driven via the drive arm 6 to open and close the main circuit contact of the circuit breaker 1. When the handle 1a of the circuit breaker 1 is locked to the ON or OFF position, as shown in the drawing, the arm 5a of the padlock 5 is hung on the lock hole opened in the cylindrical wall of the mounting base 3a, and locked. The handle 4 of the handle is prevented from moving from the ON position to the OFF position, or vice versa.
Further, as a lock mechanism of the handle device, a pull-out type lock plate is provided at the rear part of the handle, and a padlock is put on the lock plate pulled out from the handle at the handle lock position to lock the handle in the ON or OFF position. The thing of the structure made like this is also well-known (for example, refer patent document 2).

このハンドルロック方式は外部操作ハンドル装置のほか、図６に示すロータリー形ハンドルを備えた回路遮断器にも広く採用されている。すなわち、遮断器ケースのカバー上面に配したロータリー形ハンドルの把手４の後部に前記した引出し式のロックプレート４ａを設けるとともに、ケースカバーにはハンドルのロック位置に合わせて突起状のストッパ１ｂを設け、図示のＯＦＦ位置で前記ストッパ１ｂの側方にロックプレート４ａを引出して把手４がＯＦＦからＯＮ位置へ移動するのを阻止するとともに、ロックプレート４ａに南京錠を掛けて引出し位置に鎖錠する。
なお、南京錠によるハンドルロック方式は、配電盤の内部で作業員が主回路の保守，点検作業を行う場合の保安策として回路遮断器をＯＦＦ状態にロックする、あるいはハンドルの誤操作で負荷の給電が絶たれる事態を防ぐために回路遮断器をＯＮ状態にロックするようハンドルの把手に南京錠を掛けている。しかし、南京錠の管理上の問題，および施錠，解錠に手間がかかることから、前記のような特別な場合を除いて回路遮断器を頻繁に開閉操作するような使用環境では南京錠を掛けずに使うことが多い。
特開平９−２７２６２号公報 特開２００２−２５４１１号公報 This handle lock system is widely adopted not only for external operation handle devices but also for circuit breakers having a rotary handle shown in FIG. That is, the above-described drawer-type lock plate 4a is provided at the rear part of the handle 4 of the rotary handle arranged on the upper surface of the circuit breaker case cover, and the protruding stopper 1b is provided on the case cover in accordance with the lock position of the handle. The lock plate 4a is pulled out to the side of the stopper 1b in the illustrated OFF position to prevent the handle 4 from moving from the OFF position to the ON position, and a padlock is applied to the lock plate 4a to lock it in the pull-out position.
In addition, the handle lock method using a padlock locks the circuit breaker in the OFF state as a safety measure when workers perform maintenance and inspection work on the main circuit inside the switchboard, or the load power supply is cut off due to incorrect operation of the handle. In order to prevent this situation, a padlock is put on the handle handle to lock the circuit breaker to the ON state. However, because of the management problems of padlocks and the time required for locking and unlocking, it is not necessary to use padlocks in operating environments where circuit breakers are frequently opened and closed except in special cases as described above. Often used.
Japanese Patent Laid-Open No. 9-27262 JP 2002-25411 A

前記した従来構成のハンドル装置は、南京錠を掛けることでハンドルの把手をＯＮ，あるいはＯＦＦ位置に鎖錠してハンドルの誤操作を防ぐことができるものの、南京錠の管理，施錠，解錠操作の煩わしさから南京錠を掛けないで使用している状態では、不用意に物や人体が盤の前方に突き出しているハンドル装置の把手に当たったりすると、把手のＯＮ，ＯＦＦ位置が切り換わって回路遮断器が誤動作するおそれがある。
そこで、本発明は南京錠の使用によるハンドルロック機能を確保しつつ、南京錠を掛けてない使用環境の下でも、ハンドルの把手に人体，物が不用意に当たって回路遮断器が誤動作することがないような防護策を施した回路遮断器のハンドル装置を提供することにある。 Although the handle device having the above-described conventional configuration can prevent the handle from being erroneously operated by locking the handle to the ON or OFF position by applying a padlock, it is troublesome to manage, lock, and unlock the padlock. In the state where it is used without a padlock, if an object or human body accidentally hits the handle of the handle device that protrudes in front of the board, the ON / OFF position of the handle will change and the circuit breaker will There is a risk of malfunction.
Therefore, the present invention secures a handle lock function by using a padlock, and does not cause a circuit breaker to malfunction due to an accidental contact of a handle with a human body or an object even in an environment where the padlock is not applied. The object is to provide a circuit breaker handle device with protective measures.

上記目的を達成するために、本発明によれば、回路遮断器，もしくは該回路遮断器の外部付属装置として遮断器を開閉操作するハンドル装置で、南京錠ロック方式に対応する引出し式ロックプレートを備えたロータリー形ハンドルの把手をハンドルの取付ベース上に配置したものにおいて、
前記ハンドルのロック位置に対応するロックプレートの引出し領域を除き、把手の周囲を取り囲んで前記取付ベース上に把手よりも背高なガードフェンスを後付けするものとし（請求項１）、該ガードフェンスは具体的に次記のような態様で構成する。
（１）前記のガードフェンスを樹脂製の壁体とし、該壁体を取付ベースにネジ止め，係止，または圧挿して固定する（請求項２）。
（２）前項（１）におけるガードフェンスを透明樹脂製としてフェンスの側方からでも把手の位置，ベース上の表示マークを目視確認できるようにする。 In order to achieve the above object, according to the present invention, a circuit breaker or a handle device that opens and closes a circuit breaker as an external accessory device of the circuit breaker is provided with a drawer-type lock plate corresponding to a padlock lock system. In the case where the handle of the rotary type handle arranged on the handle mounting base,
A guard fence that is taller than the handle is retrofitted on the mounting base so as to surround the handle, except for the pull-out region of the lock plate corresponding to the lock position of the handle (Claim 1). Specifically, it is configured in the following manner.
(1) The guard fence is made of a resin wall, and the wall is fixed to the mounting base by screwing, locking, or press-fitting (claim 2).
(2) The guard fence in the previous item (1) is made of transparent resin so that the position of the handle and the display mark on the base can be visually confirmed even from the side of the fence.

上記の構成によれば、ハンドルの把手が裸状態のまま外部に突き出している従来構造と比べて、把手の周りにガードフェンスを設けたことで把手に外部から物や人体が不用意に触れたり，当たったりする確率は格段に小さくなり、それだけハンドルの不測な誤操作，誤動作に対する安全性が向上する。
また、このガードフェンスについて、ハンドルのロック位置に対応するロックプレートの引出し領域を切欠しておくことにより、南京錠使用のハンドルロック方式にも対応可能となり、かつガードフェンスを透明樹脂性とすることでハンドル位置，ベース上の表示マークが目視確認し易くなる。さらに、このガードフェンスをオプション部品としてハンドル装置に後付けするようにしたことで、ユーザーが回路遮断器を設置する環境の状況に応じてガードフェンスの使用，不使用を自由に選択できる。 According to the above configuration, compared to the conventional structure in which the handle handle protrudes to the outside in a bare state, a guard fence is provided around the handle, so that an object or human body may be inadvertently touched from the outside. , The probability of hitting will be significantly reduced, and the safety against unexpected misoperation and malfunction of the handle will be improved accordingly.
In addition, by cutting out the lock plate drawer area corresponding to the lock position of the handle for this guard fence, it is possible to handle the handle lock method using a padlock, and the guard fence is made of transparent resin. It is easy to visually check the handle position and the display mark on the base. Furthermore, since the guard fence is retrofitted to the handle device as an optional part, the user can freely select whether to use or not use the guard fence according to the environment in which the circuit breaker is installed.

以下、本発明の実施の形態を図１〜図３、および図４に示す実施例に基づいて説明する。なお、実施例の図中で図５，図６に対応する部材には同じ符号を付している。
図１は配電盤内に装備した回路遮断器を盤の外から手動で開閉操作する外部操作ハンドル装置に適用した実施例を示すものである。この実施例では、取付ベース３の上に配置したロータリー形ハンドルの把手４は、先記の南京錠ロック方式に対応して把手の後部に引出し式ロックプレート４ａを備えている。また、この把手４を取り囲むように取付ベース３の周縁に沿って透明樹脂製の壁体になるガードフェンス８が外付けされている。
このガードフェンス８は、回路遮断器の実使用状態で配電盤のパネル前方に突き出しているハンドルの把手４に物，人体が不用意に当たってハンドルの位置が切り換わるのを防護する役目を果たすオプション部品であり、その高さＨは把手４の高さｈよりも背高に設定されている。また、ハンドルのＯＮ位置，ＯＦＦ位置でロックプレート４ａをガードフェンス８の外側に引き出して南京錠を掛けられるようにするために、図示のようにガードフェンス８の周域一部（把手４のＯＮ位置とＯＦＦ位置との間の範囲）を欠如しておき、図２のようにハンドルのＯＦＦ位置（ＯＮ位置も同様）では、ガードフェンス８との干渉なしに把手４からロックプレート４ａを引き出して該ロックプレート４ａに開口したロック穴４ｂに南京錠が掛けられるようにしている。このような構成により、簡易ロックの機能を維持しつつ、把手のＯＮ状態ではＯＮからＯＦＦに回転させる方向に、ＯＦＦ状態ではＯＦＦからＯＮに回転させる方向からの接触を防ぐことができる。なお、図示してないが取付ベース３には、ＯＮないしＯＦＦ位置で把手４からロックプレート４ａを引き出すと、把手がこの位置に係止されるような機構を備えている。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on the examples shown in FIGS. In the drawings of the embodiment, members corresponding to those in FIGS. 5 and 6 are denoted by the same reference numerals.
FIG. 1 shows an embodiment in which a circuit breaker installed in a switchboard is applied to an external operation handle device that is manually opened and closed from the outside of the panel. In this embodiment, the handle 4 of the rotary handle disposed on the mounting base 3 is provided with a drawer-type lock plate 4a at the rear portion of the handle corresponding to the above-mentioned padlock locking method. A guard fence 8 that is a wall made of transparent resin is attached externally along the periphery of the mounting base 3 so as to surround the handle 4.
This guard fence 8 is an optional part that serves to protect the handle 4 from being accidentally hit by the handle 4 protruding from the front panel of the switchboard when the circuit breaker is actually used, and the position of the handle being switched. The height H is set higher than the height h of the handle 4. Further, in order to be able to pull out the lock plate 4a to the outside of the guard fence 8 at the ON position and OFF position of the handle so that the padlock can be hooked, a part of the peripheral area of the guard fence 8 (the ON position of the handle 4) as shown in the figure. 2), the lock plate 4a is pulled out from the handle 4 without interference with the guard fence 8 at the OFF position of the handle (same as the ON position) as shown in FIG. A padlock is hung on the lock hole 4b opened in the lock plate 4a. With such a configuration, it is possible to prevent contact from the direction of turning from ON to OFF in the ON state of the handle and from the direction of turning from OFF to ON in the OFF state, while maintaining the simple lock function. Although not shown, the mounting base 3 is provided with a mechanism that locks the handle at this position when the lock plate 4a is pulled out from the handle 4 at the ON or OFF position.

次に、ガードフェンス８の取付け構造例を図３（ａ）〜（ｄ）に示す。まず、図３（ａ）は取付ベース３の上にガードフェンス８を重ね、ハンドル装置２を装着する盤パネル７の前面に止めネジ９で共締めして固定する。また、図３（ｂ）では、ガードフェンス８の壁体基部に突起状の係合爪８ａを一体成形しておくとともに、取付ベース３の上面側には前記係合爪８ａを掛止する段付き状の係合溝３ｂを形成し、ガードフェンス８を装着する際に係合爪８ａを係合溝３ｂに嵌合して係止固定する。また、図３（ｃ）の例では、前記係合爪の代わりに圧入突起８ｂを形成し、この突起８ｂを取付ベース３の溝３ｂに圧入してガードフェンス８を固定するようにしている。さらに、図３（ｄ）の例ではガードフェンス８を多少撓ませた状態で取付ベース３の外周に嵌着して弾性的に固定している。このような固定方式を採用することで、ガードフェンス８をオプション部品としてユーザーが必要に応じて後付けすることができる。   Next, examples of the attachment structure of the guard fence 8 are shown in FIGS. First, in FIG. 3A, the guard fence 8 is overlaid on the mounting base 3, and is fixed to the front surface of the panel panel 7 on which the handle device 2 is mounted with a set screw 9. In FIG. 3 (b), a protruding engagement claw 8 a is integrally formed on the base of the wall of the guard fence 8, and the engagement claw 8 a is hooked on the upper surface side of the mounting base 3. The attached engaging groove 3b is formed, and when the guard fence 8 is mounted, the engaging claw 8a is fitted into the engaging groove 3b to be locked. In the example of FIG. 3C, a press-fitting protrusion 8b is formed instead of the engaging claw, and the protrusion 8b is press-fitted into the groove 3b of the mounting base 3 so that the guard fence 8 is fixed. Further, in the example of FIG. 3D, the guard fence 8 is slightly bent and fitted to the outer periphery of the mounting base 3 to be elastically fixed. By adopting such a fixing method, the guard fence 8 can be retrofitted as an optional part as needed.

次に、前記のガードフェンスをロータリー形ハンドル付きの回路遮断器に適用した実施例を図４に示す。この実施例では、回路遮断器１に装備したロックプレート付きハンドル把手４に対して、遮断器ケースのカバー（ハンドルの取付ベース）上面には把手４を取り囲む円環状のガードフェンス８を設置して把手４をガードしている。このガードフェンス８は、図１〜図３で述べた外部操作ハンドル装置のガードフェンスと同様に、把手４よりも背高な透明樹脂製の壁体になり、止めネジ，あるいは掛止爪を介して遮断器ケースのカバー上面に固定している。また、図示例では回路遮断器のＯＦＦ位置でハンドルの把手４から引き出したロックプレート４ａに南京錠を掛けて鎖錠するようにしており、この南京錠ロック方式に対応してガードフェンス８の周域一部に切欠部８ｃを形成しておき、この切欠部８ｃを通して把手４のロックプレート４ａをフェンスの外側に引き出せるようにしている。これにより、先記した外部操作ハンドル装置と同様に、回路遮断器の実使用状態でハンドルに物，人体が不測に当たるのを防ぐことができる。   Next, an embodiment in which the guard fence is applied to a circuit breaker with a rotary handle is shown in FIG. In this embodiment, an annular guard fence 8 surrounding the handle 4 is installed on the upper surface of the cover (handle mounting base) of the circuit breaker case with respect to the handle handle 4 with a lock plate provided in the circuit breaker 1. The handle 4 is guarded. The guard fence 8 is a wall made of transparent resin taller than the handle 4 like the guard fence of the external operation handle device described in FIGS. It is fixed to the upper surface of the cover of the circuit breaker case. In the illustrated example, the lock plate 4a pulled out from the handle handle 4 is locked with a padlock when the circuit breaker is in the OFF position. A notch 8c is formed in the part, and the lock plate 4a of the handle 4 can be pulled out of the fence through the notch 8c. As a result, similar to the above-described external operation handle device, it is possible to prevent an object or human body from hitting the handle unexpectedly in the actual use state of the circuit breaker.
