Description

本発明は、配線用遮断器や開閉器等の開閉器類のハンドルをオン、オフ操作するレバーをカム機構を利用して往復動させる開閉器類のハンドル操作装置に関するものである。   The present invention relates to a handle operating device for a switch that reciprocates a lever for turning on / off a switch of a switch such as a circuit breaker for wiring or a switch using a cam mechanism.

配線用遮断器や開閉器等の開閉器類のハンドルをオン、オフ操作するレバーをカム機構を利用して往復動させる開閉器類のハンドル操作装置としては、特許文献１に示すようにハンドル操作レバーの２枚の軸受板部を正逆回転モータを設置した取付枠に、前記正逆回転モーターで正逆回動するカム板に設けた二股状の押圧部により軸受板部に設けた突片を押圧して、前記ハンドル操作腕を揺動させて、ハンドル操作レバーのハンドル把持部に係合した開閉器類のハンドルをオン、オフするものが知れている。   As a handle operating device for a switch that reciprocates a lever for turning on / off a switch such as a circuit breaker or a switch using a cam mechanism, as shown in Patent Document 1, a handle operation is performed. Two bearing plate parts of the lever are mounted on a mounting frame on which a forward / reverse rotation motor is installed, and a projecting piece provided on the bearing plate part by a bifurcated pressing part provided on a cam plate that rotates forward and backward by the forward / reverse rotation motor. Is known to turn the handle operating arm on and off by swinging the handle operating arm and engaging the handle gripping portion of the handle operating lever.

ところが、前記のような開閉器類のハンドル操作装置は、２枚の軸受板部を取付枠の側板部と当接したものとすると、該軸受板部と側板部との間に錆等が発生した場合に軸受板部が動作不良を起こす問題がある。そこで、軸受板部と側板部との間に隙間を形成して軸受板部と側板部とが接触することなく軸支して錆等の影響を受けることなく軸受板部を動作させるものとしている。   However, in the switch operating device as described above, when the two bearing plate portions are in contact with the side plate portion of the mounting frame, rust or the like is generated between the bearing plate portion and the side plate portion. In such a case, there is a problem that the bearing plate portion malfunctions. Therefore, a gap is formed between the bearing plate portion and the side plate portion so that the bearing plate portion and the side plate portion are supported without being in contact with each other, and the bearing plate portion is operated without being affected by rust or the like. .

しかしながら、軸受板部と側板部との間に隙間を形成すると、開閉器類のハンドルのオン、オフ操作する正逆回転モーターで正逆回動するカム板に設けた二股状の押圧部が軸受板部に設けた突片を押圧して行うため、軸受板部には捻り方向の力が加わり前記隙間の間で撓み前記ハンドル操作レバーが滑らかに揺動せず開閉器類のハンドルに適切な力を加えることができないという問題がある。   However, if a gap is formed between the bearing plate portion and the side plate portion, the bifurcated pressing portion provided on the cam plate that rotates forward / reversely by a forward / reverse rotation motor that turns on / off the handle of the switch is a bearing. Since the projecting piece provided on the plate portion is pressed, a force in the twisting direction is applied to the bearing plate portion, and it is bent between the gaps, so that the handle operating lever does not swing smoothly and is suitable for a handle of a switch. There is a problem that power cannot be applied.

特開平１１−１１１１４８公報JP-A-11-111148

本発明は前記のような問題点を解決して、ハンドル操作レバーがカム機構により撓むことなく的確に揺動して開閉器類のハンドルに適切な力を加えてハンドルのオン、オフを行うことができる開閉器類のハンドル操作装置を提供することを目的として完成されたものである。   The present invention solves the above-mentioned problems, and the handle operating lever swings accurately without being bent by the cam mechanism and applies an appropriate force to the handle of the switch to turn the handle on and off. The present invention has been completed for the purpose of providing a handle operating device for a switch.

本発明の開閉器類のハンドル操作装置は、カム板を駆動する駆動手段を組み込んだフレームの両側板部に脚板部の下方を軸支した門形のハンドル操作レバーを前記カム板により往復動させて、該ハンドル操作レバーの頂板部に設けたハンドル把持レバーの先端に設けたハンドル把持部に係合させた開閉器類のハンドルをオン、オフ操作する開閉器類のハンドル操作装置において、前記門形のハンドル操作レバーの両脚板部の内面とフレームの両側板部の外面との間に間隙を形成したうえ両脚板部の内面にフレームの両側板部の外面に接触する突起もしくはフレームの両側板部の外面に両脚板部内面に接触する突起をフレームとハンドル操作レバーとの軸支部の両側に設けたことを特徴とするものである。   According to the switch operating device of the switch of the present invention, a gate-type handle operating lever that pivotally supports the lower side of the leg plate portion on both side plate portions of the frame incorporating the driving means for driving the cam plate is reciprocated by the cam plate. In the handle operating device for a switch for turning on / off the handle of a switch engaged with a handle grip provided at the tip of the handle grip lever provided on the top plate of the handle control lever, Protrusions that form a gap between the inner surfaces of both leg plate portions of the handle control lever and the outer surfaces of both side plate portions of the frame, and that contact the outer surfaces of both side plate portions of the frame on the inner surface of both leg plate portions or both side plates of the frame Protrusions that contact the inner surfaces of both leg plate portions are provided on both sides of the shaft support portion of the frame and the handle operating lever.

前記のような本発明は、門形のハンドル操作レバーの両脚板部の内面とフレームの両側板部の外面との間に間隙を形成したうえ両脚板部の内面にフレームの両側板部の外面に接触する突起もしくはフレームの両側板部の外面に両脚板部内面に接触する突起をフレームとハンドル操作レバーとの軸支部の両側に設けたものである。そうすると、ハンドル操作レバーをカム板により往復動させる場合に、両脚板部の内面もしくはフレームの両側板部の外面に設けた突起がフレームの両側板部の外面にもしくは両脚板部の内面に接触したまま揺動するので、ハンドル操作レバーの両脚板部は突起を介してフレームの両側板部の外面に接触するたま該両脚板部はこの両側板部の外面に規制されるので、ハンドル操作レバーがカム板の回動による撚れた力を受けても撓むことなく的確に揺動して開閉器類のハンドルに適切な力を加えて該ハンドルのオン、オフを行うことができるものである。また、突起をフレームとの軸支部の両側に設けたことにより往復どちらの動きに対しても撓むことがない。   In the present invention as described above, a gap is formed between the inner surfaces of the two leg plate portions of the portal handle operating lever and the outer surfaces of the two side plate portions of the frame, and the outer surfaces of the two side plate portions of the frame are formed on the inner surfaces of the two leg plate portions. Or projections that contact the inner surfaces of both leg plate portions on both sides of the shaft support portion of the frame and the handle operating lever. Then, when the handle operating lever is reciprocated by the cam plate, the protrusions provided on the inner surfaces of both leg plate portions or the outer surface of both side plate portions of the frame come into contact with the outer surface of both side plate portions of the frame or the inner surfaces of both leg plate portions. Since both the leg plate portions of the handle operating lever come into contact with the outer surfaces of the both side plate portions of the frame through the projections, the both leg plate portions are regulated by the outer surfaces of the both side plate portions. Even if it receives a twisted force due to the rotation of the cam plate, the handle can be turned on and off by accurately swinging without bending and applying an appropriate force to the switch handle. . Further, since the projections are provided on both sides of the shaft support portion with the frame, the projection does not bend with respect to either reciprocal movement.

また、ハンドル操作レバーの両脚板部の内面とフレームの両側板部の外面との接触が突起であることにより接触抵抗が少なく、また、脚板部は突起と軸支部で側板部に接触しているので、脚板部の他の個所が側板部に接触してこすれることなくスムーズに揺動できるものである。   Further, the contact between the inner surface of both leg plate portions of the handle operating lever and the outer surface of both side plate portions of the frame is a projection, so that the contact resistance is low, and the leg plate portion is in contact with the side plate portion by the projection and the shaft support portion. Therefore, the other portions of the leg plate portion can smoothly swing without being rubbed against the side plate portion.

次に、本発明の好ましい実施の形態を図を参照して説明する。
１はハンドル操作装置の側方に配線用遮断器６や開閉器等の開閉器類を搭載する取付台部１０ａを併設したベース１０に取り付ける断面門形のフレームであり、該フレーム１にはロータリ型ソレノイド、正逆回転モータ等の駆動手段２が組み込こまれているとともに該駆動手段２により駆動するカム板３が設けられている。４は頂板部４０の両側下方に脚板部４１、４１を連設した門形のハンドル操作レバーであり、該門形のハンドル操作レバー４は前記フレーム１の両側板部１１、１１に脚板部４１、４１の下方を軸支部４ａにより軸支している。 Next, a preferred embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a cross-sectional gate-shaped frame that is attached to a base 10 that is provided with a mounting base portion 10a that mounts switches such as a circuit breaker 6 and a switch on the side of the handle operating device. A driving means 2 such as a type solenoid and a forward / reverse rotating motor is incorporated, and a cam plate 3 driven by the driving means 2 is provided. Reference numeral 4 denotes a gate-shaped handle operating lever in which leg plate portions 41, 41 are continuously provided on both lower sides of the top plate portion 40, and the gate-shaped handle operating lever 4 is connected to the both side plates 11, 11 of the frame 1. , 41 is pivotally supported by a pivotal support 4a.

そして、該ハンドル操作レバー４は前記駆動手段２により駆動するカム板３により往復動されて該ハンドル操作レバー４の頂板部４０に横方向にスライド自在に設けたハンドル把持レバー５の先端に設けたハンドル把持部５１に係合させた取付台部１０ａに搭載した配線用遮断器６のハンドル６１をオン、オフ操作するものである。   The handle operating lever 4 is provided at the tip of a handle gripping lever 5 which is reciprocated by the cam plate 3 driven by the driving means 2 and is slidable in the lateral direction on the top plate portion 40 of the handle operating lever 4. The handle 61 of the circuit breaker 6 mounted on the mount 10a engaged with the handle grip 51 is turned on and off.

また、前記門形のハンドル操作レバー４の両脚板部４１、４１の内面とフレーム１の両側板部１１、１１の外面との間には間隙を形成したうえ両脚板部４１、４１の内面にフレーム１の両側板部１１、１１の外面に接触する突起４１ａをそれぞれ軸支部４ａの両側に１点ずつ計２点設けてある。   In addition, a gap is formed between the inner surfaces of the both leg plate portions 41 and 41 of the portal handle operating lever 4 and the outer surfaces of the both side plate portions 11 and 11 of the frame 1 and the inner surfaces of the both leg plate portions 41 and 41 are formed. Two protrusions 41a that contact the outer surfaces of both side plate portions 11 and 11 of the frame 1 are provided on each side of the shaft support portion 4a.

このように両脚板部４１、４１の内面に突起４１ａをそれぞれ２点ずつ設けたことにより、ハンドル操作レバー４をカム板３により往復動させる場合に、両脚板部４１の内面に設けた２点の突起４１ａ、４１ａがフレーム１の両側板部１１、１１の外面に接触した状態で揺動するので、ハンドル操作レバー４の両脚板部４１、４１は突起４１ａを介してフレーム１の両側板部１１、１１の外面に常時接触しているので該両脚板部４１、４１はこの両側板部１１、１１の外面に規制されて、ハンドル操作レバー４がカム板３の回動動作により撓むことないものである。また、突起４１ａを軸支部４ａの両側に設けたことにより押圧部３ａが突片４２を押圧する方向から見た場合、左の脚板部４１の軸支部４ａの両側に設けられた突起４１ａ、４１ａのうち、手前側の突起４１ａ及び、右の脚板部４１の軸支部４ａの両側に設けられた突起４１ａ、４１ａのうち、奥側の突起４１ａが作用し、撓みを防止しており、往復どちらの動きに対しても撓むことがないものである。   Thus, by providing two protrusions 41a on the inner surfaces of the both leg plate portions 41, 41, two points provided on the inner surfaces of the both leg plate portions 41 when the handle operating lever 4 is reciprocated by the cam plate 3. Since the projections 41a and 41a swing in a state where the projections 41a and 41a are in contact with the outer surfaces of the side plates 11 and 11 of the frame 1, both the leg plates 41 and 41 of the handle operating lever 4 are connected to the side plates of the frame 1 via the projection 41a. 11 and 11 are always in contact with the outer surfaces of the eleventh and eleven, the leg plate portions 41 and 41 are regulated by the outer surfaces of the two side plate portions 11 and 11, and the handle operating lever 4 is bent by the rotation of the cam plate 3. There is nothing. Further, by providing the protrusions 41a on both sides of the shaft support part 4a, the protrusions 41a and 41a provided on both sides of the shaft support part 4a of the left leg plate part 41 when viewed from the direction in which the pressing part 3a presses the protrusions 42. Of the protrusions 41a on the front side and the protrusions 41a and 41a provided on both sides of the shaft support part 4a of the right leg plate part 41, the protrusion 41a on the back side acts to prevent bending. It does not bend even with respect to the movement of.

また、両脚板部４１、４１の内面とフレーム１の両側板部１１、１１の外面との間には突起４１ａにより接触している個所以外には間隙が残されることとなるので、脚板部４１の内面又は側板部１１の外面に錆等が発生しても該錆等が脚板部４１の内面と側板部１１の外面とを間隙を埋めてまでも連繋する虞がないので脚板部４１の作動が阻害されることがないものである。   Further, a gap is left between the inner surfaces of the both leg plate portions 41 and 41 and the outer surfaces of the both side plate portions 11 and 11 of the frame 1 except for the portions in contact with the projections 41a. Even if rust or the like is generated on the inner surface or the outer surface of the side plate portion 11, there is no possibility that the rust or the like will connect the inner surface of the leg plate portion 41 and the outer surface of the side plate portion 11 even if the gap is filled. Is not inhibited.

さらに、前記したとおり両脚板部４１、４１の内面にフレーム１の両側板部１１、１１の外面との接触が２点であることにより接触抵抗が少なく、また、脚板部４１は該２点の突起４１ａ、４１ａと支軸の３点で側板部１１に接触しているので、脚板部１１の他の個所が側板部１１に接触してこすれることがないので駆動手段２に負荷をかけることなく的確に揺動して配線用遮断器６のハンドル６１に適切な力を加えてハンドルのオン、オフを行うことができるものである。なお、本実施形態では突起をそれぞれ軸支部の両側１点ずつ、計２点設けたものとして説明したが、２点以上あってもよい。また、本実施形態では突起をハンドル操作レバー４の内面に設けたものとして説明したが、フレームの両脚板部１１のハンドル操作レバー４が揺動する範囲内の軸支部の両側に突起を設けてもよい。   Further, as described above, there are two points of contact between the inner surfaces of the both leg plate portions 41 and 41 and the outer surfaces of the both side plate portions 11 and 11 of the frame 1, so that the contact resistance is low, and the leg plate portion 41 has two points. Since the projections 41a and 41a and the support shaft are in contact with the side plate portion 11, the other portions of the leg plate portion 11 do not come into contact with the side plate portion 11 and are not rubbed. The handle can be turned on and off by swinging accurately and applying an appropriate force to the handle 61 of the circuit breaker 6 for wiring. In the present embodiment, it has been described that the protrusions are provided at two points on each side of the shaft support, for a total of two points, but there may be two or more points. In the present embodiment, the projection is described as being provided on the inner surface of the handle operation lever 4. However, the projection is provided on both sides of the shaft support portion within the range in which the handle operation lever 4 of the both leg plate portions 11 of the frame swings. Also good.

なお、前記ハンドル操作レバー４をカム板３により往復動させる具体的手段は、図５、図６及び図７に示すようにロータリ型ソレノイド、正逆回転モータ等の駆動手段２に押圧部３ａ、３ｂを対向して設けた二股状のカム板３を取り付け、該カム板３の押圧部３ａ、３ｂは一方の脚板部４に内向きに折曲して設けた突片４２を正逆に押圧するように臨ませている。すなわち、このカム板３の押圧部３ａ、３ｂの間に突片４２を介在させてその表裏面を駆動手段２の正逆回転により一方の押圧部３ａが正方向に、他方の押圧部３ｂが逆方向に突片４２を押圧するとしている。   The specific means for reciprocating the handle operating lever 4 with the cam plate 3 is shown in FIGS. 5, 6 and 7 with the driving means 2 such as a rotary solenoid, a forward / reverse rotating motor, etc. A bifurcated cam plate 3 provided facing 3b is attached, and the pressing portions 3a and 3b of the cam plate 3 press forwardly and reversely the protruding pieces 42 bent inwardly on one leg plate portion 4. I'm going to do it. That is, the projecting piece 42 is interposed between the pressing portions 3a and 3b of the cam plate 3, and one of the pressing portions 3a is moved in the forward direction and the other pressing portion 3b is moved forward and backward by rotating the driving means 2 forward and backward. It is assumed that the projecting piece 42 is pressed in the opposite direction.

また、前記図示の実施形態では、開閉器類としては遮断機構の組み込んだ配線用遮断器を例示したが、遮断機構の無い開閉器であってもよいことは勿論である。   In the illustrated embodiment, as the switches, the circuit breaker for wiring with a built-in breaker mechanism is exemplified, but it is needless to say that the breaker without a breaker mechanism may be used.
