Opfindelsen angår et lukke for et dæksel af en især elektriske apparater optagende kasse ifølge overbegrebet til krav 1.BACKGROUND OF THE INVENTION 1. Field of the Invention

Fra US-PS 3 770 306 kendes et lukke for en branddør, ved 5 hvilken klinken er anbragt i et metalhus, som er indsat i et udsnit, der strækker sig over en del af dørens tykkelse. Som aktiveringsdel tjener et drejeligt greb, som med en ekscen-terstift griber ind i en længdeslids af klinken.From U.S. Pat. No. 3,770,306, a fire door closure is known at 5, the latch of which is arranged in a metal housing inserted in a section extending over a portion of the door's thickness. As an actuating part, a pivotal handle which with an eccentric pin engages a longitudinal slot of the latch.

Formålet med opfindelsen er at angive et lukke af den i ind-10 ledningen beskrevne art, som ved enkel opbygning er egnet til tyndvæggede dæksler og udadtil er beskyttet mod uvedkommende åbning samt mod forurening.The object of the invention is to provide a closure of the type described in the preamble, which, by simple construction, is suitable for thin-walled covers and is externally protected from unauthorized opening as well as from pollution.

Denne opgave løses ved hjælp af de i den kendetegnende del af krav 1 angivne kendetegn. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16This problem is solved by means of the characteristics specified in the characterizing part of claim 1. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

Ved denne konstruktion føres klinken umiddelbart i udsnittet 2 af det forholdsvis tynde dæksel. Noterne kan svare til dæk 3 slets vægtykkelse, således at dette i det væsentlige gennem 4 gående kan have samme tykkelse. Afdækningsdelen, som ligele 5 des fastgøres umiddelbart på dækslet, sørger på den ene side 6 for, at alle væsentlige dele af klinken er afdækket og der 7 for ikke er tilgængelig udefra, og giver på den anden side 8 en god beskyttelse mod forurening. Lukket giver en varig 9 låsning, som kun kan frigøres af en kompetent person, som 10 stikker den af lukket uafhængige aktiveringsdel ind gennem 11 afdækningsdelens gennemgangsåbning, indtil medbringerflader 12 samvirker kraftoverførende. Gennemgangsåbningens stilling 13 har den fordel, at en simpel forskydningsbevægelse af akti 14 veringsdelen er tilstrækkelig til frigørelse af lukket. Der 15 efter danner afdækningsdelen et modleje for aktiveringsde- 16 len, som med aktiveringsdelen tillader at udøve kræfter i dækslets åbningsretning. Hvis altså fx dækslet er udformet som svingbar dør, kan klinken ved forskydning af aktive- 150314 2 ringsdelen i dækselplanet trækkes tilbage fra modlejefladen på kassevæggen, og så kan svingningen til åben stilling ske ved at bevæge aktiveringsdelen vinkelret på dækselplanet.In this construction, the latch is passed immediately in section 2 of the relatively thin cover. The notes may correspond to the wall thickness of tire 3, so that this can be substantially the same thickness throughout 4. The cover portion, which is also attached immediately to the cover, ensures, on the one hand 6, that all essential parts of the latch are covered and that 7 is not available from the outside, and on the other hand 8 provides good protection against contamination. The closure provides a durable 9 lock, which can only be released by a competent person, who plugs in the closed independent actuator portion through the cover opening 11 of the cover portion until the carrier surfaces 12 cooperate with the transmitter. The position 13 of the passage opening has the advantage that a simple displacement movement of the actuating part is sufficient for release of the closure. Thereafter, the cover member forms a counter bearing for the actuating member 16, which with the actuating member allows exerting forces in the opening direction of the cover. Thus, for example, if the cover is designed as a pivotal door, the latch may be withdrawn from the counter face on the box wall by displacing the actuating member of the cover plane, and then the pivot to open position may be effected by moving the actuating member perpendicular to the cover plane.

Ved udformningen i krav 2 kan aktiveringsdelen valgfrit for-5 blive på lukket, hvis det til stadighed eller i perioder er tilladeligt, at enhver vilkårlig trediemand kan frigøre låsen. Der er imidlertid også den mulighed, at man kan fjerne aktiveringsdelen, således at trediemand ikke er i stand til at frigøre låsen.In the design of claim 2, the actuating member may optionally remain closed if it is permissible for any or all periods of time for any third party to release the lock. However, there is also the possibility that the actuating member can be removed so that the third party is not able to release the lock.

10 Ved udformningen i krav 3 tillader fjederarmene at udføre låsningen ved hjælp af en kunststofdel. De har derudover den fordel, at de giver åbningsdelen en vis længde, som er en fordel ved udøvelsen af de vinkelret på dækselplanet virkende åbningskræfter.In the embodiment of claim 3, the spring arms allow the locking to be carried out by means of a plastic part. In addition, they have the advantage that they give the opening part a certain length, which is an advantage in the application of the opening forces acting perpendicular to the cover plane.

15 Ved udformningen i krav 4 kan slidsen være tilpasset tværsnittet af aktiveringsdelens gliderdel. Underlagsfladen gør det lettere at indføre aktiveringsdelen i denne slids. Derudover tjener denne underlagsflade til at fuldstændiggøre dækslet, som i dette område har en udtagning til gennemfø-20 ring af klinken.In the embodiment of claim 4, the slot may be adapted to the cross-section of the slider portion of the actuating member. The support surface facilitates insertion of the actuating member into this slot. In addition, this backing surface serves to complete the cover, which in this area has a recess for carrying the latch.

Fastgørelsen ved hjælp af fjedernæser ifølge krav 5 giver en varig forbindelse af meget enkel form.The fastening by means of spring noses according to claim 5 provides a durable connection of very simple form.

Føringsforlængelserne i krav 6 overgriber dækselvæggen i tilslutning til udsparingen og forbedrer føringen betyde-25 ligt.The guide extensions of claim 6 overlay the cover wall adjacent to the recess and significantly improve the guide.

Ved udformningen i krav 7 fastholdes fjederen pladsbesparende og uden anvendelse af yderligere dele.In the design of claim 7, the spring is maintained space-saving and without the use of additional parts.

Ved videreudformningen i krav 8 dannes der et hulrum af variabel størrelse, hvori fjederen i det væsentlige er fuld-30 stændig indesluttet.In the further embodiment of claim 8, a variable size cavity is formed in which the spring is substantially completely enclosed.

Det ved udformningen i krav 9 mellem fordybningen og klinke-delen med de to sideribber forblivende rum formår netop at optage aktiveringsdelens glider med sine fjederarme.In the design of claim 9, between the recess and the latch portion with the two side ribs remaining precisely manages to receive the slider of the actuating part with its spring arms.

Opfindelsen beskrives nærmere nedenstående ved hjælp af et 5 på tegningen vist, foretrukket udførelseseksempel, der viser i fig. 1 en kasse med døragtigt dæksel, til hvilket et lukke ifølge opfindelsen er anvendeligt, fig. 2 en del af dækslet, klinken, afdækningsdelen og ak-10 tiveringselementet for lukket ifølge opfindelsen i perspektivistisk fremstilling med de enkelte dele trukket fra hinanden, fig. 3 et snit langs med linien A-A i fig. 1, fig. 4 klinken set bagfra, 15 fig. 5 klinken set fra siden og fig. 6 et snit gennem afdækningsdelen.The invention is further described below by means of a preferred embodiment shown in the drawing, which shows in FIG. 1 shows a box with a door-like cover to which a closure according to the invention is applicable; FIG. 2 is a perspective view of the cover, latch, cover portion and actuator element of the closure according to the invention with the individual parts pulled apart; FIG. 3 is a section along the line A-A of FIG. 1, FIG. 4, the rear view, FIG. 5 is a side view of the latch and FIG. 6 is a section through the cover portion.

Fig. 1 viser en kasse 1 med flere kassevægge 2 samt et døragtigt dæksel 3, som over hængsler 4 er forbundet med kassen 1. Denne kasse kan især tjene til optagelse af elektriske 20 apparater, som elektroniske termostater, regulatorer, styreapparater, overvågningskredsløb og lignende. Både kassen og dækslet består af kunststof. Dækslet kan være gennemsigtigt.FIG. 1 shows a box 1 with a plurality of box walls 2 and a door-like cover 3, which is connected to the box 1. over hinges 4. This box can especially serve for receiving electrical appliances, such as electronic thermostats, regulators, control devices, monitoring circuits and the like. Both the box and the cover are made of plastic. The cover may be transparent.

Opfindelsen vedrører et lukke 5 mellem kasse og dæksel. De enkelte dele af dette lukke er nærmere vist i fig. 2. 1 Dækslet 3 har en udsnit 6. Der er anbragt på siden fremspringende sidevægge 7 og 8 samt en fjederfatning 9. Deri- 150314 4 mellem er der med udsparingen forbundne udtagninger 10 og 11. Portil har udsparingen 6 to udvidelser 12 og 13.The invention relates to a closure 5 between box and cover. The individual parts of this closure are shown in more detail in FIG. 2. 1 The cover 3 has a section 6. The side projecting side walls 7 and 8 and a spring mounting 9. There are recesses 10 and 11. The port 6 has the recess 6 and two extensions 12 and 13.

En klinke 14, som også er vist i fig. 4 og 5» har på siden forløbende føringsnoter 15 og 16, som udsparingens 6 side-5 vægge 7 og 8 kan gribe ind i. I tilslutning dertil er der anbragt en indvendig føringsforlængelse 17 og en udvendig føringsforlængelse 18, som på udsparingens ende griber over den på udsparingens 6 ende tilsluttende dækseldel* Herved danner føringsforlængelsen 17 en rendeagtig afdækning, som 10 griber over fjederfatningen 9. Indvendigt er der et hulrum 19 med en fjederunderstøtning 20. En skruefjeder 21 understøttes på den ene side på denne fjederunderstøtning 20 og på den anden side på fjederfatningen 9. I sammenbygget tilstand er fjederen 21 derfor i det væsentlige fuldstændig 15 indkapslet. Klinken 14 har en forende 22, som formår at gribe bag en modlejeflade 23 i kassevæggen 2. Den ud af dækslet 3 ragende del består af en plade 24 og to sideribber 25 og 26, som på den forreste ende danner en medbringerflade 27 og på den bageste ende en arreteringsflade 28.A latch 14, also shown in FIG. 4 and 5 »have laterally extending guide notes 15 and 16 to which the side-5 walls 7 and 8 of the recess 6 can engage. In addition, an inner guide extension 17 and an outer guide extension 18 are provided which grip the end of the recess. the cover portion 17 adhering to the end of the recess * Hereby, the guide extension 17 forms a gutter-like cover 10 which engages the spring socket 9. Inside there is a cavity 19 with a spring support 20. A screw spring 21 is supported on one side on this spring support 20 and on the other. Therefore, in the assembled state, the spring 21 is substantially completely encapsulated. The latch 14 has a front end 22 which manages to engage behind a counter bearing surface 23 in the box wall 2. The portion projecting out of the cover 3 consists of a plate 24 and two side ribs 25 and 26, which at the front end form a carrier surface 27 and on it. rear end an arresting surface 28.

20 En afdækningsdel 29 griber ud over den fra dækslet fremspringende del af klinken 14. Den er fastgjort på dækslet med fjedernæser 30 og 31, som griber ind i udtagningerne 10 og 11. En slidsformet gennemgangsåbning 32 er anbragt på den mod kassevæggen 2 vendte side. Foran denne er der lejret en 25 underlagsflade 33. Den på denne måde fortykkede del 34 tjener til at udfylde udsparingen 6 i udvidelsernes 12 og 13 område. En fordybning 35 optager pladen 24 med klinkens 14 sideribber 25 og 26.20 A cover portion 29 engages the portion protruding from the cover 14 of the latch 14. It is secured to the cover with spring noses 30 and 31 which engage the recesses 10 and 11. A slotted aperture 32 is disposed on the side facing the box wall 2. In front of this is mounted a 25 support surface 33. The thus-thickened part 34 serves to fill the recess 6 in the area of the extensions 12 and 13. A recess 35 occupies the plate 24 with the side ribs 25 and 26 of the latch 14.

En aktiveringsdel 36 har en gliderdel 37, som på den ene en-30 de bærer et greb 38 og på den anden ende har en som kant udformet medbringerflade 39, som kan samvirke med medbringer-fladerne 27. Til kanten slutter der sig to fjederarme 40 og 41, som på enderne bærer låsefremspring 42 og 43. Disse kan 150314 5 gribe bag arreteringsfladerne 18. Tykkelsen af gliderdelen 37 og fjederarmene 40 og 41 svarer til gennemgangsåbningens 32 højde samt det frie rum mellem pladen 24 og fordybningens 35 bund.An actuating member 36 has a slider member 37 which, on one end, carries a grip 38 and on the other end, has a bearing surface 39 which can cooperate with the bearing surfaces 27. Two spring arms 40 are joined to the edge. and 41, which carry on the ends locking projections 42 and 43. These may engage behind the retaining surfaces 18. The thickness of the slider portion 37 and the spring arms 40 and 41 corresponds to the height of the passage opening 32 as well as the free space between the plate 24 and the bottom of the recess 35.

5 Ved monteringen bliver først skruefjederen 21 og klinken 14 skubbet fra forsiden ind i udsparingen 6. Så fastgøres afdækningsdelen 29 i udtagningerne 10, 11. Dermed er lukket klar til brug. Ved at fasttrykke dækslet 3 kan det gå i låsestilling.5 At mounting, first the screw spring 21 and the latch 14 are pushed from the front into the recess 6. Then the cover part 29 is secured in the recesses 10, 11. Thus, the closure is ready for use. By pressing the cover 3 it can enter the lock position.

10 Til åbning er det nødvendigt at føre aktiveringsdelen 36 ind gennem gennemgangsåbningen 32, indtil medbringerfladen 39 slår mod medbringerfladerne 27. Ved yderligere forskydning af aktiveringsdelen i dækslets 3 plan skubbes klinken tilbage, og lukket frigives. Udøves der nu en kraft vinkelret på 15 dækselplanet på aktiveringsdelens 38 greb, så kan dækslet let svinges op eller ned, fordi de tilsvarende kræfter fra gliderdelen 37 og aktiveringsdelens 36 fjederarme 40 og 41' overføres til afdækningsdelen 29 og derfra til dækslet.10 For opening, it is necessary to insert the actuating member 36 through the passage opening 32 until the guide surface 39 beats against the driving faces 27. Upon further displacement of the actuating member in the plane of the cover 3, the latch is pushed back and the closure is released. If a force is applied at right angles to the cover plane of the grip of the actuating member 38, then the cover can be easily pivoted up or down because the corresponding forces from the slider member 37 and the spring arms 40 and 41 'of the actuating member 36 are transferred to the cover member 29 and from there to the cover.

Heraf kan man se, at man ved at trække aktiveringsdelen 36 20 ud gør det umuligt for en uvedkommende person at åbne lukket. Der er dog også den mulighed, at man kan lade aktiveringsdelen forblive i den indskubbede stilling; på grund af låseforbindelsen kan det ikke falde ud. Konstrueres fjederarmene 40 og 41 meget stive, kan man også etablere en varig 25 forbindelse mellem aktiveringsdel og klinke.From this it can be seen that by pulling out the actuating part 36 20 it makes it impossible for an unauthorized person to open closed. However, there is also the possibility that the actuating member can be left in the pushed position; due to the locking connection, it cannot fall out. If the spring arms 40 and 41 are designed to be very rigid, a permanent connection between the actuating part and the latch can also be established.

I stedet for den viste aktiveringsdel 36 kan der også anvendes andre aktiveringsdele, som har medbringerflader, der kan samvirke med medbringerflader på glideren. I hvert tilfælde er det tilstrækkeligt med små kræfter for at skubbe klinken 30 tilbage, og aktiveringsdelen går derved så langt ind i afdækningselementet, at det uden vanskeligheder er muligt at løfte dækslet.Instead of the actuating member 36 shown, other actuating members may also be used which have carrier surfaces which can cooperate with driver surfaces on the slider. In each case, small forces are sufficient to push the latch 30 back and the actuating member thereby extends so far into the cover member that it is possible to lift the cover without difficulty.
