Opfindelsen angår en manuel betjeningsindretning til brug i forbindelse med en afbryder, som er indbygget i et aflukke og indrettet til at kunne blive aktiveret ved hjælp af et på en åbnelig låge anbragt håndtag via en drejelig afbryderaksel, 5 hvilken betjeningsindretning omfatter en med håndtaget fast forbundet første koblingspart, som er drejeligt lejret i lågen, samt en på afbryderakselen monteret anden koblingspart, hvilke to koblingsparter er indrettet til at gå i indgreb med hinanden ved lukning af lågen og har indbyrdes samvirkende 10 føringsflader, som muliggør indskydning af de to koblingsparter i hinanden under udligning af stillingsforskelle herimellem ved hjælp af udligningsorganer, og hvor der findes spærreorganer til sikring imod åbning og lukning af lågen, medens afbryderen er tilkoblet.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a manual control device for use in connection with a switch built into a housing and adapted to be actuated by means of a handle mounted on an open door via a rotary switch shaft, the control device comprising a handle connected to the handle. a first coupling part which is pivotally mounted in the door, and a second coupling part mounted on the switch shaft, which two coupling parts are arranged to engage each other by closing the door and have mutually interacting guiding surfaces which allow the two coupling parts to be pushed into each other while compensating for differences in positions therewith by means of compensating means, and where there are locking means for securing against opening and closing of the door while the switch is switched on.

Med hensyn til sikkerhed og til beskyttelse mod milieuet er afbrydere til industribrug almindeligvis indbygget i kabinetter. Imidlertid er det ønskeligt at kunne betjene sådanne afbrydere uden at skulle åbne kabinettets låge, og afbryderen er derfor 20 forsynet med en aksel, som er så lang, at betjeningshåndtaget kan anbringes på ydersiden af lågen. Idet det er væsentligt at kunne åbne lågen med henblik på udskiftning af sikringer, er håndtaget almindeligvis lejret i lågen og med en klokobling forbundet med afbryderakselen. Imidlertid kræver sikkerheden, 25 at lågen kun kan åbnes, når afbryderen er i stilling "afbrudt". Derfor er håndtagsfunktionen almindeligvis forbundet med en aflåsning af lågen. Endvidere er der et krav om, at håndtaget ikke må kunne sammenkobles med afbryderen, når der er uoverensstemmelse mellem håndtagets stilling og afbryderens virke-30 lige stilling. Da det er vanskeligt ved seriemæssig montage af afbrydere at sikre fuldstændig korrekt placering af afbryderen i forhold til klokoblingsdelen i håndtaget, skal der også være en udligningsanordning i forbindelse med betjeningsaggregatet.As far as safety and environmental protection are concerned, switches for industrial use are usually built into cabinets. However, it is desirable to be able to operate such switches without having to open the door of the cabinet, and the switch is therefore provided with a shaft which is so long that the operating handle can be placed on the outside of the door. As it is essential to be able to open the door for the purpose of replacing fuses, the handle is usually enclosed in the door and with a clockwise coupling to the switch shaft. However, the safety requires that the door can only be opened when the switch is in the "off" position. Therefore, the handle function is usually associated with a locking of the door. Furthermore, there is a requirement that the handle must not be interconnected with the switch when there is a discrepancy between the position of the handle and the actual position of the switch. Since it is difficult to ensure complete correct positioning of the switch in relation to the clockwise coupling part of the handle in serial mounting, there must also be a compensating device in connection with the control unit.

Der kendes adskillige løsninger på ovennævnte problemer. Fælles for dem alle er, at de består af mekaniske enkeltdele, som med korrekt relativ placering skal monteres på henholdsvis 35 2 150422Several solutions to the above problems are known. Common to all of them is that they consist of mechanical individual parts, which with correct relative position must be mounted on 35 2 150422 respectively.

håndtag og afbryderaksel. Dette formindsker sikkerheden, idet fejlmulighederne er større, og det medfører tillige en forøget installationstid. Især lågeaflåsningen er kompliceret og i de fleste tilfælde afhængig af korrekt indgreb mellem låse-5 anordningen og den del, som er fast forbundet med afbryderens aksel.handle and switch shaft. This reduces the security as the failure possibilities are greater, and it also increases the installation time. In particular, the cover locking is complicated and in most cases dependent on proper engagement between the locking device and the part which is firmly connected to the shaft of the switch.

Fra USA patentskrift nr. 2.698.361 kendes en betjeningsindretning til en afbryder, som har en afbryderaksel og et på en to låge anbragt håndtag. Håndtaget er forbundet med en første koblingspart i form af en modtagedel , og afbryderakselen er forbundet med en anden koblingspart i form af en indstiksdel. Indstiksdelen har aksialt forløbende fedre, medens modtagedelen har hertil svarende spalter med skråt forløbende indløb, som 15 muliggør vinkelindstilling af de to koblingsparter i forhold til hinanden. Betjeningsindretningen ifølge USA patentskriftet har endvidere spærreorganer i form af en på den anden koblingspart tildannet- bueformet plade med en spalte i periferien.US Patent No. 2,698,361 discloses a control device for a switch having a switch shaft and a handle located on a two door. The handle is connected to a first coupling part in the form of a receiving part, and the switch shaft is connected to a second coupling part in the form of a plug part. The insert portion has axially extending fats, while the receiving portion has corresponding slots with inclined inlets which allow angular adjustment of the two coupling portions relative to each other. Furthermore, the operating device of the United States patent has locking means in the form of an arcuate plate formed on the other coupling part with a slot in the periphery.

Denne spalte er beregnet til at skulle samvirke med spidsen 20 af en krog, som er tilknyttet den første koblingspart på en sådan måde, at lågen kun kan åbnes,hvis spidsen befinder sig direkte ud for spalten i den anden koblingspart. Som følge af at udligningen af vinkelindstillingen imellem de to koblingsparter foregår ved glidning af de to koblingsparter mod hin-25 anden, er der fare for et sådant slid af de to parter, at det -for korrekt funktion af spalten og krogen er nødvendigt, at spalten fremstilles med særlig stort spillerum.This slot is intended to cooperate with the tip 20 of a hook attached to the first coupling member in such a way that the door can only be opened if the tip is directly next to the slot in the second coupling part. Due to the fact that the angular adjustment between the two coupling parts is equalized by sliding the two coupling parts against each other, there is a danger of such wear of the two parts that the proper functioning of the slot and the hook is necessary that the slit is made with particularly large clearance.

Betjeningsindretningen ifølge opfindelsen er ejendommelig 30 ved, at den anden koblingspart omfatter en med den første koblingspart samvirkende indgrebsdel og en på afbryderakselen fast monteret monteringsdel, hvor indgrebsdelen og monteringsdelen er indbyrdes forbundet ved hjælp af udligningsorganerne, som er indrettet til at muliggøre forskydning af indgrebsdelen 35 i enhver retning vinkelret på afbryderakselens akse.The operating device according to the invention is characterized in that the second coupling part comprises an engagement part cooperating with the first coupling part and a mounting part fixed to the switch shaft, wherein the engagement part and the mounting part are interconnected by means of the equalizing means arranged to allow displacement of the engagement part 35 in any direction perpendicular to the axis of the switch shaft.

Herved opnås, at der tilvejebringes en betjeningsindretning, som er forholdsvis, kompakt og til trods herfor åbner mulighed 3 150422Hereby it is achieved that a control device is provided which is relatively, compact and yet allows option 3 150422

for udligning af stillingsforskelle imellem afbryderen og håndtaget i enhver retning, uden at slitage af dele, der glider hen imod hinanden, stiller krav om, at samvirkende styreflader og spærreorganer skal fremstilles med stort spillerum ud over 5 de normale tolerancer, der skal være til stede, for at de enkelte dele let lader sig bevæge i forhold til hinanden.to compensate for differences in position between the switch and the handle in any direction, without the wear of sliding parts towards each other, requires that cooperating control surfaces and locking means must be manufactured with a large clearance beyond the normal tolerances that must be present. , so that the individual parts can easily move in relation to each other.

Dette skyldes især, at udligningsorganerne findes inden for selve den anden koblingspart, således at udligningen af stillingsforskelle imellem de to koblingsparter udelukkende foregår 10 inden for den anden koblingspart, således at selve aflåsningen eller spærringen af de to koblingsparter i forhold til hinanden virker imellem den første koblingspart og den anden koblingsparts indgrebsdel, efter at indgrebsdelen har fået sin placering korrigeret, dvs. at indgrebsdelen befinder sig i 15 en stilling, som er uafhængig af slitage af udligningsorga-nerne. Da den anden koblingsparts indgrebsdel lader sig forskyde i en hvilken som helst retning vinkelret på afbryderakselens akse, kan håndtaget monteres forholdsvis hurtigt og let uden overholdelse af særlig store tolerancekrav. Som 20 følge af at udligningsorganerne befinder sig i permanent forbindelse med hinanden inden for den anden koblingsparts område, åbnes der også mulighed for permanent opretholdt smøring af de heri indgående dele.This is mainly due to the fact that the equalizing means are within the second coupling part, so that the equalization of position differences between the two coupling parts takes place exclusively within the second coupling part, so that the locking or locking of the two coupling parts in relation to each other works between the first coupling part and the engagement part of the other coupling part after the engagement part has been corrected, ie. the engagement member is in a position independent of wear of the compensating means. Since the engagement part of the other coupling member can be displaced in any direction perpendicular to the axis of the switch shaft, the handle can be mounted relatively quickly and easily without complying with very high tolerance requirements. Due to the fact that the equalizing means are permanently in contact with each other within the area of the other coupling party, it is also possible to permanently maintain lubrication of the parts contained therein.

25 Ifølge opfindelsen kan den anden koblingsparts indgrebsdels ydre form være ikke-rotationssymmetrisk og tildannet som ind-stiksdel til et komplementært tildannet modtagende hul i den første koblingspart, idet indstiksdelen er tilspidset i retning frem imod den første koblingspart. Herved opnås en særlig 30 hensigtsmæssig betjeningsindretning, som på enkel måde sikrer korrekt styring af koblingsparterne i forhold til hinanden.According to the invention, the outer shape of the second coupling part can be non-rotationally symmetrical and formed as a plug part for a complementary formed receiving hole in the first coupling part, the insert part being pointed towards the first coupling part. Hereby a particularly convenient control device is obtained, which in a simple way ensures correct control of the coupling parts in relation to each other.

Derudover kan ifølge opfindelsen spærreorgånerne omfatte en fjederforspændt kulisseplade i håndtagets leje, og som er 35 indrettet til at blive skudt til side af den anden koblingsparts indgrebsdel under dennes passage ind i den første koblingspart, medens kulissepladen har dele til samvirken med en skrå flade anbragt på et kantområde af indgrebsdelen, når denne sammen 4 150422 med håndtaget befinder sig i afbrydningsstillingen, så at koblingsparternes indbyrdes spærring udløses ved åbning af lågen. Herved opnås en yderst enkelt virkende fastlåsning af koblingsparterne til hinanden og udnyttelse af indgrebsdelen til at 5 udløse denne fastlåsning.In addition, according to the invention, the locking members may comprise a spring-biased backing plate in the handle bearing, and which is arranged to be pushed aside by the engagement part of the other coupling part during its passage into the first coupling part, while the backing plate has parts for cooperation with an inclined surface mounted on an edge region of the engagement member when together with the handle it is in the switching position so that the interlocking of the coupling parts is released when the door is opened. This results in an extremely simple locking of the coupling parts to each other and utilization of the engagement part to release this locking.

Endelig kan ifølge opfindelsen den anden koblingsparts monteringsdel være en bøsning til optagelse af afbryderakselen, hvilken bøsning har mindst to huller til montering af en ind-adragende stift til samvirken med en langsgående not på afbryderakselen ved isætning af akselen i bøsningen, hvorved der på enkel måde opnås sikkerhed for korrekt montering af koblingsparten på afbryderakselen ved på forhånd at anbringe en stift i det hul, der svarer til den pågældende kabinettype.Finally, according to the invention, the mounting portion of the other coupling member may be a sleeve for receiving the switch shaft which has at least two holes for mounting a retractable pin for cooperating with a longitudinal groove on the switch shaft by inserting the shaft into the bush, assurance is obtained for correct mounting of the coupling part on the switch shaft by placing a pin in advance in the hole corresponding to the type of cabinet in question.

Opfindelsen forklares nedenfor under henvisning til tegningen, hvor fig. 1 viser en konstruktion i henhold til kendt teknik, fig. 2 viser en konstruktion i henhold til opfindelsen, og fig. 3 viser detaljer i denne konstruktion.The invention is explained below with reference to the drawing, in which fig. 1 shows a prior art construction; FIG. 2 shows a construction according to the invention, and fig. 3 shows details of this construction.

I fig. 1 vises et håndtag 1, som er monteret på en håndtagsaksel 2. Denne bærer en plade med stifter 3, som kan opnå ind-25 greb med slidser 4 i en i det væsentlige cirkulær plade 5.In FIG. 1, a handle 1 is shown mounted on a handle shaft 2. This carries a plate with pins 3 which can obtain engagement with slots 4 in a substantially circular plate 5.

Omsluttende pladens 5 centrum er der en slids 6, som er placeret vinkelret på forbindelseslinien mellem slidserne 4. I slidsen 6 er anbragt enden af en afbryders betjeningsaksel 7.Surrounding the center of the plate 5 there is a slot 6 which is perpendicular to the connection line between the slots 4. In the slot 6 is placed the end of a switch shaft 7.

Idet slidsen 6 er længere end afbryderakselens tværdimenison, 30 kan pladen 5 bevæges sideværts på afbryderakselen 7. Pladen 5 har tillige en udskæring 8 over en del af periferien. Ved brug af dette kendte betjeningsaggregat skal afbryderakselen 7 tilpasses i længde til afbryderens placering i kabinettet. Der skal etableres indgreb mellem stifterne 3 og slidserne 4, og 35 det kan kun ske, når der er overensstemmelse mellem afbryde rens stilling og håndtagets stilling. Dersom håndtagsakselens retning ikke er sammenfaldende med afbryderakselens, så vil forskydninger af stifterne 3 i slidserne 4 og af afbryderakse- 5 150422 len 7 i slidsen 6 foretage en udligning under rotationen. Med henblik på opnåelse af en aflåsning af lågen, når afbryderen er sluttet, rager en klo 9 i fast forbindelse ned lågen fren, således at den griber fat i pladen 5, medmindre pladen er i en 5 sådan stilling, som svarer til stilling "afbrudt". I denne stilling er kloen 9 ud for udskæringen 8 i pladen 5.Since the slot 6 is longer than the transverse dimension of the switch shaft, the plate 5 can be moved laterally on the switch shaft 7. The plate 5 also has a cut-out 8 over part of the periphery. When using this known control unit, the switch shaft 7 must be adjusted in length to the position of the switch in the cabinet. Interference must be established between the pins 3 and the slots 4, and this can only happen when there is a correspondence between the position of the cleaner and the position of the handle. If the direction of the handle shaft does not coincide with that of the switch shaft, then displacements of the pins 3 in the slots 4 and of the switch shaft 7 in the slot 6 will equalize during rotation. In order to obtain a lock of the door when the switch is closed, a claw 9 in fixed connection projects down the door so that it grips the plate 5 unless the plate is in a position corresponding to position "switched off. ". In this position, the claw 9 is off the cutout 8 in the plate 5.

Det er indlysende, at et kendt betjeningsaggregat son beskrevet ovenfor har visse mekaniske svagheder og ulemper i brug.It is obvious that a known control unit described above has certain mechanical weaknesses and disadvantages in use.

Ved skæv placering af håndtaget i lågen i forhold til afbryderen i kabinettet, hvor udligningen er stor, vil sliddet, især i slidsen 6, blive stort, hvorved- der udvikles slør. Kloen 9 skal have et stort fangområde, idet den foruden at kompensere for sløret også skal fungere sikkert, selv ned fuld kompensa-tion ved stifterne 3 i slidserne 4, dvs. ved stor udligning.If the handle is skewed in the door in relation to the switch in the cabinet, where the equalization is large, the wear, especially in the slot 6, will be large, thereby causing the veil to develop. The claw 9 must have a large catch area, in addition to compensating for the veil, it must also function safely, even down full compensation at the pins 3 in the slots 4, ie. by great equalization.

Disse ulemper undgås fuldstændig ved konstruktionen ifølge opfindelsen, som vises på fig. 2. En koblingspart 10 omfatter en indgrebsdel i form af et hus, som har en tilspidsning 11 og rummer udligningsorganerne, og den monteres ved hjælp af en 2Q bøsning 12 på afbryderens aksel 7. Tilspidsningen 11 letter indføringen i et hul 13, som indgår i endnu en koblingspart i håndtaget 1. Huset 10 til udligningsorganerne har på sin ene flade en feder 14, som samvirker med en tilsvarende not 15 i hullet 13 i håndtaget, når hullet indtager den rigtige stil-2g ling i forhold til huset 10. I nær forbindelse med hullet 13 er der i håndtagets leje 16 anbragt en glider 17, son er fjederbelastet. Glideren 17 presses til side ved indføringen af huset 10 i hullet 13, og efter fuldstændig indføring låser glideren for udtrækning. Denne funktion benyttes til låsning 3q af lågen 30, idet håndtaget i denne stilling ikke kan skilles fra afbryderakselen 7. Der eksisterer i praksis en mulighed for at "overliste" låsen ved indsætning af et specialværktøj udefra. Dette er ikke vist, og det hører til kendt teknik.These disadvantages are completely avoided by the construction according to the invention shown in FIG. 2. A coupling part 10 comprises an engagement part in the form of a housing having a taper 11 and accommodating the equalizing means, and it is mounted by means of a 2Q bushing 12 on the shaft of the switch 7. The taper 11 facilitates insertion into a hole 13 which is included in the another coupling member in the handle 1. The housing 10 for the compensating means has on its one surface a spring 14 which cooperates with a corresponding groove 15 in the hole 13 in the handle when the hole takes the correct position relative to the housing 10. In the near In connection with the hole 13, a slide 17 is arranged in the handle bed 16, which is spring loaded. The slide 17 is pressed aside at the insertion of the housing 10 into the hole 13, and after complete insertion, the slide locks for extraction. This function is used for locking 3q of the door 30, since the handle in this position cannot be separated from the switch shaft 7. There is in practice an opportunity to "over-frame" the lock by inserting a special tool from the outside. This is not shown and it is a known technique.

Lågen skal kunne åbnes i afbryderens stilling "afbrudt", og 3g det opnås ved en skrå flanke '18 på den ene kant af huset, som ved tilbagetrækning i den rigtige stilling, kan presse kulissepladen (glideren) 17 tilbage. Den store fordel ved aflåsning i henhold til opfindelsen fren for den kendte teknik ligger i, 150422 β at aflåsningen virker på den den af betjeningsindretningen, som har fået sin mekaniske placering korrigeret. Det vil sige, at låseorganerne ikke behøver at have et stort spillerum, idet de altid skal virke på samme sted, og det er således blot nød-5 vendigt at arbejde med sædvanlige mekaniske tolerancer for let indføring og udtrækning.It should be possible to open the door in the "off" position of the switch, and 3g this is achieved by an inclined flank '18 on one edge of the housing which, when retracted in the correct position, can push back the backing plate (slider) 17. The great advantage of interlocking according to the invention from the prior art lies in the fact that the interlocking acts on that of the control device which has had its mechanical location corrected. That is, the locking means need not have a great deal of leeway, as they must always operate in the same place, and thus it is only necessary to work with usual mechanical tolerances for easy insertion and extraction.

På fig. 2 er tilsvaende vist, hvorledes det er opnået, at der altid kan opretholdes den sammenhæng mellem håndtagsposition og betjeningstilstand for afbryderen, som er tilsigtet fra fabrikantens side. Ved at bøsningen 12 har mindst to huller 23, 24 til montering af en stift til samvirken med en langsgående not 22 på afbryderakselen ved isætning af akselen i bøsningen, kan dette opnås i de tilfælde, hvor afbryderen har en fast indbygget aksel såvel som i de tilfælde, hvor en firkantet 15 aksel ved montage afskæres på længde og anbringes i et dertil indrettet hul i afbryderen. I det sidste tilfælde forudsætter det blot, at der i dette hul, til samvirken med noten i den firkantede aksel, er anbragt en indragende stift eller knast. Virkemåden bliver da følgende: akselen 7 med noten 22 afskæres på længde og stikkes i afbryderens (ikke viste) med stift forsynede hul. Dette kan kun foretages på én måde. Herefter anbringes koblingsparten 10 ved hjælp af sin bøsning 12 på apparatakselen 7. Dette kan ligeledes kun foretages på én måde, idet der er anbragt en indragende stift i hullet 24, således at akselen 7 kun kan skubbes ind i muffen 12, når stiften kan glide i noten 22. Ved hjælp af den viste skrue fastspændes bøsningen på akselen. Lågen 30 kan lukkes, når federen 14 føres ind i noten 15 i håndtaget, og kun da. Dermed er det 3Q entydigt sikret, at man altid ved lukket låge kan aflæse af bryderens betjeningstilstand. Dersom det skulle være ønsket at overholde en bestemt konvention om håndtagets absolutte orientering på lågen (eksempelvis: lodret = sluttet; vandret = afbrudt), så kan der opstå problemer, dersom en afbryder af pladsmæssige grunde kun kan monteres eksempelvis lodret, når O o afbryderakselens not er placeret med henblik på afbryderens vandrette montage. I denne situation kan stiften i hullet 24 i bøsningen 12 ved en bevidst brug af værktøj presses ud og 7 150422 isættes hullet 23, hvorved der er kompenseret for den ændrede placering af afbryderen. Der er ialt fire huller i bøsningen 12 svarende til fire forskellige orienteringer af noten 22, som stiften skal samvirke med.In FIG. 2 is similarly shown how it has been achieved that the relationship between the handle position and the operating state of the switch can always be maintained as intended by the manufacturer. By having the bush 12 at least two holes 23, 24 for mounting a pin for cooperation with a longitudinal groove 22 on the switch shaft when inserting the shaft into the bush, this can be achieved in cases where the switch has a fixed built-in shaft as well as in the shaft. in cases where a square 15 shaft, when mounted, is cut lengthwise and placed in a corresponding hole in the switch. In the latter case, it merely presupposes that in this hole, for the interaction with the groove in the square shaft, a projecting pin or cam is arranged. The operation then becomes as follows: the shaft 7 with the groove 22 is cut lengthwise and inserted into the pin (not shown) with a rigidly provided hole. This can only be done in one way. Thereafter, the coupling part 10 is mounted by means of its bushing 12 on the apparatus shaft 7. This can also only be done in one way, with a projecting pin inserted in the hole 24, so that the shaft 7 can only be pushed into the sleeve 12 when the pin can slide in the groove 22. Using the screw shown, tighten the bushing on the shaft. The gate 30 can be closed when the spring 14 is inserted into the groove 15 in the handle, and only then. In this way, 3Q is unequivocally ensured that you can always read the operating mode of the switch at the closed door. If it is desired to comply with a certain convention on the handle's absolute orientation on the door (for example: vertical = closed; horizontal = disconnected), problems may arise if a switch for space reasons can only be mounted, for example, vertically, when the o slot is located for the horizontal mounting of the switch. In this situation, the pin in the hole 24 in the bush 12 can be pressed out by a deliberate use of tools and the hole 23 is inserted, thereby compensating for the changed position of the switch. There are a total of four holes in the bush 12 corresponding to four different orientations of the groove 22 with which the pin is to cooperate.

5 På fig. 3 er vist hjertet af koblingsparten 10. Det er den del, som kompenserer for, at afbryderakselen 7 ikke nødvendigvis har samme omdrejningsakse som håndtaget 1, selv om de er parallelle. Der er således tale om at overføre en drejende bevægelse mellem to parallelle aksler, og det gøres rent kinematisk som beskrevet i forbindelse med gennemgangen af den kendte teknik (fig. 1): ved to glidebevægelser vinkelret på hinanden. Disse udføres ifølge opfindelsen ved, at der er en maskindel, som er vist på fig. 3B, og som består af en plade , _ (19) med vinkelret på hinanden anbragte federe 20 og 21. Disse samvirker med noter i henholdsvis huset 10 og den i huset indragende del af bøsningen 12. Den på fig. 3B viste del kommer således til at overføre bevægelsen af håndtaget 1, som driver koblingspartens 10 hus, til afbryderakselen 7 gennem muffen 2Q 12. Dette er vist ved de forskelligartede skraveringer på fig.5 In FIG. 3 is shown the heart of the coupling part 10. It is the part which compensates that the switch shaft 7 does not necessarily have the same axis of rotation as the handle 1, although they are parallel. Thus, it is a transfer of rotational motion between two parallel shafts, and it is made purely kinematic as described in connection with the review of the prior art (Fig. 1): by two sliding motions perpendicular to each other. These are carried out according to the invention in that there is a machine part shown in FIG. 3B, and consisting of a plate (19) with feathers 20 and 21. perpendicular to each other, cooperate with grooves in the housing 10 and the housing portion of the bush 12 respectively. 3B thus transmits the movement of the handle 1, which drives the housing of the coupling part 10, to the switch shaft 7 through the sleeve 2Q 12. This is shown by the different shading of FIG.

3a. Noterne er længere end federne 20 og 21 for at tillade den sideværts bevægelse i to på hinanden vinkelrette retninger.3a. The notes are longer than springs 20 and 21 to allow the lateral movement in two mutually perpendicular directions.

Det skal bemærkes, at kinematisk udfører den på fig. 3B afbildede del samme opgave som den cirkulære plade 5 på fig. 1.It should be noted that kinematically the embodiment of FIG. 3B depicts the same task as the circular plate 5 of FIG. First

Idet aflåsningen af lågen 30 i henhold til opfindelsen sker 30 ved forskydning af kulissepladen 17 parallelt med lågen 30, foreligger der en simpel mulighed for at opnå aflåsning af såvel håndtagets 1 rotation som lågens 30 åbning ved hjælp af en stift, som fra håndtagets forside skubbes parallelt med håndtagsaksen til indgreb med huller i såvel låge 30 som kulis-35 seplade 17. En sådan stift kan aflåses med en hængelås, således at der kun kan opnås autoriseret adgang til enten betjening eller åbning af kabinettet.Since the locking of the door 30 according to the invention takes place by displacing the backing plate 17 parallel to the door 30, there is a simple possibility of obtaining locking of both the rotation of the handle 1 and the opening of the door 30 by means of a pin which is pushed from the front of the handle. parallel to the handle shaft for engaging holes in both door 30 and backing plate 17. Such a pin can be locked with a padlock so that only authorized access to either operation or opening of the cabinet can be obtained.

Claims

By means of a compensating device in the form of the second coupling part, which is fixedly mounted on the switch shaft, a smaller construction, permanent lubrication, a reduced total weight and greatly simplified mounting of the handle in the front plate is achieved. 5 Patent claims.
