463 G58 Dessa syftemål förverkligas enligt föreliggande uppfinning genom att en strömställare av det inledningsvis angivna slaget i huvud- sak är så beskaffad som anges i den kännetecknande delen av patent- kravet 1. 463 G58 These objects are realized according to the present invention in that a switch of the type initially indicated is substantially as described in the characterizing part of claim 1.

Ytterligare kännetecken av och fördelar med uppfinningen framgår av följande beskrivning under hänvisning till bifogade ritningar, som visar ett föredraget, dock ej begränsande utföringsexempel på en strämställare enligt uppfinningen. I detalj föreställer: Fig. 1 en sektionsvy av en strömställare enligt uppfinningen in- rättad som tryckbrytare i viloläge, Fig. 2 en motsvarande vy av samma brytare inrättad som drag- och tryckbrytare, varvid viloläget antyds med heldragna linjer och skiftningsläget med streckade linjer, Fig. 3 & 4 brytaren enligt fig. 2 sedd framifrån resp. bakifrån, Fig. 5 & 6 vyer motsvarande fig. 1 & 2 av ett modifierat utförande.Additional features and advantages of the invention will become apparent from the following description taken in conjunction with the accompanying drawings, which show a preferred, but not limiting, embodiment of a switch according to the invention. In detail: Fig. 1 shows a sectional view of a switch according to the invention arranged as a pressure switch in the rest position, Fig. 2 a corresponding view of the same switch arranged as a draft and pressure switch, the rest position being indicated by solid lines and the shift position with dashed lines, Fig. 3 & 4 the switch according to Fig. 2 seen from the front resp. rear view, Fig. 5 & 6 views corresponding to Figs. 1 & 2 of a modified embodiment.

I ritningsfigurerna betecknas med 10 ett hus till en anordning av något slag, som är försedd med en strömställare, t.ex. en elektrisk strömlist, en belysningsarmatur e.dyl., som ej visas i figurerna.In the drawing figures, 10 denotes a housing for a device of some kind, which is provided with a switch, e.g. an electric current strip, a lighting fixture and the like, which are not shown in the figures.

Huset kan vara en separat del eller integrerad i sagda anordning. och uppvisar exempelvis sidoväggar 8 och 9, en framvägg 11 och en I öppen baksida 12. Företrädesvis på insidan av framväggen 11 är fäst ett manöverhus 13 med sidoväggar 14 och gavlar 15, 16, som kan vara i huvudsak runda, samt med en bakvägg 2, vars ändpartier 17, 18 är runda för att mjukt ansluta till gavlarnas form.The housing can be a separate part or integrated in said device. and has, for example, side walls 8 and 9, a front wall 11 and an open rear side 12. Preferably on the inside of the front wall 11 is attached an operating housing 13 with side walls 14 and ends 15, 16, which may be substantially round, and with a rear wall 2 , the end portions 17, 18 of which are round to softly connect to the shape of the ends.

På insidan av bakväggen 2 är anordnad en känd brytarmekanism 1 med en manöverknapp 19, som är anordnad att skjuta ut i riktning mot framväggen 11 och anligga mot in- eller baksidan av en i denna in- fälld tryckplatta 6, vars kontur lämpligen följer innerkonturen av manöverhuset med något spel, så att tryckplattan kan tryckas in i detta hus, varvid den häktas med ett svängutsprång 5 på korta, från husets 13 sidoväggar i riktning mot varandra utskjutande axeltappar 20. Svängutsprånget har lämpligen skålliknande form med en resp. 5 058' _)\ 3 ' 4 ände av tryckplattan från långkant till långkant följande vägg 21, som är rundad inåt centralt vid 22 och vid sina ändar 23 en bit in på långkanterna av tryckplattan. Inom övergångsområdet mellan nämn- da långkanter och resp. kortsida är väggen i sina mittemot varandra belägna områden försedd med trattliknande inskärningar 24 och in- nerst anordnade underskurna styrhål 25, i vilka nämnda axeltappar är avsedda att glida via nämnda inskärningar, när man pressar tryck- plattan mot tapparna, så att tryckplattan på detta sätt hålles fast och samtidigt kan svängas runt tapparna i begränsad utsträckning.Arranged on the inside of the rear wall 2 is a known switch mechanism 1 with an operating button 19, which is arranged to project in the direction of the front wall 11 and abut against the inside or back side of a pressure plate 6 recessed in it, the contour of which suitably follows the inner contour of the control housing with some play, so that the pressure plate can be pushed into this housing, whereby it is hooked with a pivot projection 5 on short shaft pins 20 projecting from each other in the side walls of the housing in the direction of each other. 5 058 '_) \ 3' 4 end of the pressure plate from long edge to long edge following wall 21, which is rounded inwards centrally at 22 and at its ends 23 a bit into the long edges of the pressure plate. Within the transition area between the mentioned long edges and resp. short side, the wall in its opposite areas is provided with funnel-like notches 24 and inwardly arranged undercut guide holes 25, in which said shaft pins are intended to slide via said notches, when the pressure plate is pressed against the pins, so that the pressure plate in this way held and at the same time can be swung around the pins to a limited extent.

Tryckplattans exakta viloläge enligt fig. l garanteras av manöver- knappen 19, som fjädrande trycker på plattans insida, och företrä- desvis även av ett arreteringsutsprång 26, som häktar inom tryck- plattans relativt svängutsprånget andra ändområde bakom framväggen ll och kan införas först i detta läge, innan man trycker fast tryck- plattan på det beskrivna viset.The exact resting position of the pressure plate according to Fig. 1 is guaranteed by the control button 19, which resiliently presses on the inside of the plate, and preferably also by a locking projection 26, which hooks within the second end area of the pressure plate relative to the pivot projection position, before pressing the pressure plate in the manner described.

Inom nämnda andra ändområde är tryckplattan på utsidan lämpligen försedd med en delsfärliknande upphöjning 27 och på insidan med ett snörfäste 7, vilket lämpligen är utformat med nämnda arrete- ringsutsprång i ett stycke. Vid detta fäste är färankrad ena änden av ett dragsnöre 3, som är fört förbi och/eller genom gaveln 16 genom en speciell styrning 28, vidare förbi utsidan av rundningarna 17 och 18 med passering genom en styrning 29 på utsidan av bakväg- gen 2 och slutligen genom en styrning 30 i husets gavel 15 och ut genom en öppning 31 i framväggen 11 precis utanför tryckplattans infästa svängände. Den fritt utskjutande snöränden är försedd med en dragknapp 4. Samtliga styrningar 28, 29, 30 kan innefatta mot manöverhusets 13 inre 32 öppna spår, vilka i fråga om styrningarna 29 och 30 bägränsas utåt av t.ex. U-formiga styrrännor.Within said second end area, the pressure plate is suitably provided on the outside with a partial sphere-like elevation 27 and on the inside with a string attachment 7, which is suitably formed with said locking projections in one piece. At this bracket, one end of a pull cord 3 is anchored, which is passed past and / or through the end wall 16 by a special guide 28, further past the outside of the roundings 17 and 18 with passage through a guide 29 on the outside of the rear wall 2 and finally through a guide 30 in the gable 15 of the housing and out through an opening 31 in the front wall 11 just outside the fixed pivot end of the pressure plate. The freely projecting snow end is provided with a pull button 4. All guides 28, 29, 30 may comprise open grooves towards the inner 32 of the control housing 13, which in the case of the guides 29 and 30 are limited outwards by e.g. U-shaped guide gutters.

En sådan strömställare är mycket lätt att tillverka, montera och använda som antingen tryckbrytare utan synligt snöre eller som kom- binerad drag-ochtryckbrytare, varvid man enligt önskemål kan an- vända sig av tryckplattan och/eller dragsnöret för att bryta eller koppla på den elektriska strömmen. Tillvägagångssättet vid monte- ring är följande: n 058 a C; Vid den ännu icke i manöverhuset 13 intryckta tryckplattan förankras den ena änden av snöret 3, varefter - medan brytarmekanismen är på plats - tryckplattan föres in i huset 13 med arreteringsutsprånget 26 häktande bakom framväggen ll och tryckes fast, så att axeltappar- na 20 snäpper in i styrhålen 25 och tryckplattan intar det med hel- dragna linjer visade läget enligt fig. l eller 2. Härvid låter man den andra snöränden med dragknappen 4 antingen vara insatt i husets 13 inre 32 enligt fig. 1, varvid alltså snöre och dragknapp är helt osynliga och dolda, eller fritt uthängande enligt fig. 2 - 4, varvid tryckplattans manöverände kan pâverkas via direktkontakt med t.ex. ett finger och/eller dragsnöret, som verkar i samma område och i sam- ma riktning, såsom framgår av fig. 2.Such a switch is very easy to manufacture, mount and use as either a pressure switch without visible cord or as a combined pull and pressure switch, whereby the pressure plate and / or the pull cord can be used as desired to break or switch on the electrical the current. The mounting procedure is as follows: n 058 a C; At the pressure plate not yet pressed into the control housing 13, one end of the string 3 is anchored, after which - while the switch mechanism is in place - the pressure plate is inserted into the housing 13 with the locking projection 26 hooked behind the front wall 11 and pressed so that the shaft pins 20 snap in in the guide holes 25 and the pressure plate assumes the position shown in solid lines according to Fig. 1 or 2. Hereby the other end of the string with the pull button 4 is either inserted into the inner 32 of the housing 13 according to Fig. 1, whereby the string and pull button are completely invisible and hidden, or freely hanging according to Figs. 2 - 4, whereby the operating end of the pressure plate can be influenced via direct contact with e.g. a finger and / or drawstring acting in the same area and in the same direction, as shown in Fig. 2.

Givetvis kan påverkningssättet ändras i efterhand. Vill man fälla in eller ut snöre och dragknapp, så frigör man tryckplattan genom att bakifrån pressa den från sitt ingrepp med axeltapparna med ett verktyg, t.ex. en skruvmejsel, varefter man fäller in eller ut snö- re och dragknapp och trycker tillbaka plattan. I sitt infällda läge stör snöre och dragknapp manöverbarheten på intet sätt, eftersom de fälls in i det delutrymme av manöverhusets inre, som inte behövs för tryckplattans svängutrymme.Of course, the method of influence can be changed afterwards. If you want to fold in or out the string and zipper, you release the pressure plate by pushing it from the back from its engagement with the shaft pins with a tool, e.g. a screwdriver, after which you fold in or out the string and pull button and push the plate back. In their retracted position, the string and zipper do not interfere with the maneuverability in any way, since they fold in into the subspace of the interior of the control housing, which is not needed for the pivot space of the pressure plate.

Med fördel kan arreteringsutsprånget 26 gripa in i och styras i sid- led av spåret 28. Det är också möjligt att anordna svängutsprånget 5 i mitten av tryckplattan, så att utrymmet bakom den ena änden av tryckplattan friläggs och snöre samt tryckknapp ev kan föras in resp. ut vid ensidigt påverkad tryckplatta utan att man behöver helt taga loss den. I ett sådant fall måste dock brytarmekanismen anordnas vid ena änden av tryckplattan och således ej centralt.Advantageously, the locking projection 26 can engage in and be guided laterally by the groove 28. It is also possible to arrange the pivoting projection 5 in the middle of the pressure plate, so that the space behind one end of the pressure plate is exposed and string and push button can be inserted resp. . out on one-sidedly affected pressure plate without having to completely remove it. In such a case, however, the switch mechanism must be arranged at one end of the pressure plate and thus not centrally.

Ytterligare modifikationer och kompletteringar är tänkbara inom ra- men för uppfinningstanken och följande patentkrav. Således kan man även tänka sig, att snöret kan hänga direkt fritt ner från tryckplat- tan, särskilt vid nämnda centrala svängningsupphängning av tryckplat- tan, i vilket fall således beskrivna styrningar kan undvaras och gi- vetvis också arreteringsutsprånget 26. 63 058 .ﬁ > Det i fig. 5 och 6 visade modifierade utförandet uppvisar en tryckplatta 6, vars ena ände är svängbart infäst vid manöverhuset eller huset 10, vilka hus i samtliga utföranden givetvis kan vara kombinerade på godtyckligt sätt, exempelvis till att bilda enbart ett hus. Infästníngen är företrädesvis av typen gångjärnsled 33, som kan vara påverkad, t.ex. omgiven av en skruvfjäder 34 För att hål- la plattan tryckt mot brytarmekanismen. Snöre och dragknapp infäl- les lämpligen i delutrymmet bakom snörfästet 7 och är dragna kring en trissa e.dyl. 35 gränsande till samma omrâde, så att avsedd brytverkan erhålles och plattan kan dras/tryckas inåt. Plattan kan svängas utåt t.ex. med hjälp av ett vid dess fria ände anordnat utsprång 36, som man kan gripa tag i medelst ett verktyg, eventu- ellt enbart en fingernagel, mot verkan av fjäderns 34 kraft, så att i detta utfällda läge snöre och knapp kan tas ut eller föras in.Further modifications and additions are conceivable within the scope of the inventive concept and the following claims. Thus, it is also conceivable that the string can hang directly free down from the pressure plate, especially at said central oscillation suspension of the pressure plate, in which case the guides thus described can be dispensed with and of course also the locking projection 26. 63 058 .ﬁ> The modified embodiment shown in Figs. 5 and 6 has a pressure plate 6, one end of which is pivotally attached to the operating housing or housing 10, which housings in all embodiments can of course be combined in any manner, for example to form only one housing. The attachment is preferably of the hinge joint type 33, which may be affected, e.g. surrounded by a coil spring 34 To keep the plate pressed against the switch mechanism. The string and zipper are suitably recessed in the subspace behind the string mount 7 and are pulled around a pulley or the like. Adjacent to the same area, so that the intended breaking action is obtained and the plate can be pulled / pushed inwards. The plate can be swung outwards e.g. by means of a projection 36 arranged at its free end, which can be grasped by means of a tool, possibly only a fingernail, against the action of the force of the spring 34, so that in this unfolded position string and button can be taken out or guided in.
