Sikringsindretning til indstillingsspindel for et armaturAdjusting spindle for a luminaire

Opfindelsen angår en sikringsindretning, således som den er beskrevet i den indledende delaf kravl.The invention relates to a securing device as described in the preamble of claim 1.

Fra GB 2 378 234 A kendes en sikringsindretning til forhindring en ubeføjet betjening af en indstillingsspindel, med en spindeladapter, som kan fastgøres på en konustap af indstillingsspindelen, og en værktøjsadapter, som kan påsættes på spindeladapteren. Spindeladapteren har med henblik på påsætning og betjening med værktøjsadapteren en cylinderdel, som er koncentrisk i forhold til en midterakse, og som en cylindrisk excentertap rager ud over ved endefladen. En påsætningsdel af værktøjsadapteren har en cylindrisk indvendig optagelse, som er indført koncentrisk i forhold til midteraksen, samt en excentrisk indvendig optagelse, som kan bringes i indgreb med spindeladapterens excentertap. Endvidere er værktøjsadapteren forsynet med en konustap, som er anbragt koncentrisk i forhold til længdemidteraksen, og på hvilken der kan påsættes et standardiseret værktøj, som er tiltænkt en umiddelbar betjening af indstillingsspindelen.GB 2 378 234 A discloses a preventive device for preventing unauthorized operation of an adjusting spindle, with a spindle adapter which can be attached to a cone pin of the adjusting spindle and a tool adapter which can be attached to the spindle adapter. The spindle adapter has a cylinder part which is concentric relative to a center axis and which a cylindrical eccentric pin protrudes at the end surface for application and operation with the tool adapter. An attachment portion of the tool adapter has a cylindrical inner recess that is inserted concentrically relative to the center axis, as well as an eccentric internal recess that can be engaged by the spindle adapter's eccentric pin. Furthermore, the tool adapter is provided with a cone pin which is located concentric to the longitudinal center axis and to which a standardized tool intended for immediate operation of the adjusting spindle can be mounted.

Formålet med opfindelsen er at tilvejebringe en sikringsindretning i form af en påsætning på en indstillingsspindel for et armatur, hvilken sikringsindretning effektivt forhindrer en ubeføjet betjening.The object of the invention is to provide a securing device in the form of an attachment to an adjusting spindle of a luminaire which effectively prevents unauthorized operation.

Dette formål med opfindelsen opfyldes ved hjælp af de træk, der er anført i den kendetegnende del af krav 1. Den overraskende fordel er her, at man ved at udforme en kernedel og en påsætningskappe, som dækker den og omgiver den ved omkredsen, og som er frit drejelig uden passende sammenkoblingsmidler hos et betjeningsmiddel, kan forhindre, at der frembringes en indstillingskraft på en indstillingsspindel.This object of the invention is accomplished by the features set forth in the characterizing part of claim 1. The surprising advantage here is that by forming a core member and an attachment sheath which covers and surrounds it at the perimeter, and which is freely rotatable without the appropriate coupling means of an actuator, can prevent the actuation force of an adjusting spindle from being produced.

2 DK 2008 00177 U42 DK 2008 00177 U4

Udformninger, således som de beskrevet i kravene 2 til 5, er også fordelagtige, fordi det ved hjælp af disse ikke er muligt at betjene indstillingsspindelen med værktøjer, som ikke udøver nogen sammenkoblingsvirkning mellem kernedelen og den frit drejelige påsætningskappe.Designs, such as those described in claims 2 to 5, are also advantageous because by means of these it is not possible to operate the adjusting spindle with tools which do not have an interconnecting effect between the core part and the freely rotatable attachment sheath.

Der er også mulighed for en udformning ifølge krav 6, hvor det er muligt at dimensionere sikringsindretningen, således at den passer til forskellige betjeningskræfter, der er afhængige af et armaturs konstruktionstype.There is also the possibility of a design according to claim 6, in which it is possible to design the securing device to suit different operating forces dependent on the type of luminaire's design.

10 I henhold til de i krav 7 til 12 beskrevne fordelagtige videreudviklinger opnås der et meget kompakt konstruktionselement for påsætningskappen, og fremstillingen og monteringen gøres lettere.10 According to the advantageous further developments described in claims 7 to 12, a very compact structural element for the attachment sheath is obtained and the manufacture and assembly are facilitated.

Ved hjælp af de i krav 13 og 14 beskrevne fordelagtige videreudviklinger bli-15 ver det lettere at demontere sikringspåsætningen fra indstillingsspindelens konustap, især med henblik på reparations- eller vedligeholdelsesarbejder.By means of the advantageous further developments described in claims 13 and 14, it becomes easier to disassemble the securing attachment from the adjusting spindle's cone loss, especially for repair or maintenance work.

Den i krav 15 beskrevne fordelagtige videreudvikling giver mulighed for en billig seriefremstilling ved en høj fremstillingskvalitet og styrke til frembringel-20 se af den nødvendige betjeningskraft.The advantageous further development described in claim 15 allows for a low-cost serial production at a high manufacturing quality and strength to produce the necessary operating power.

De i krav 16 til 19 beskrevne fordelagtige videreudviklinger er også fordelagtige på grund af en lav produktionsudgift.The advantageous further developments described in claims 16 to 19 are also advantageous because of a low production cost.

25 Endelig er en udformning ifølge krav 20 også fordelagtig, hvorved der kan vælges forskellige materialevarianter svarende til de krav, der stilles til betjeningsmidlet.Finally, a design according to claim 20 is also advantageous, whereby different material variants can be selected corresponding to the requirements of the operating means.

Med henblik på en bedre forståelse af opfindelsen vil denne blive forklaret 30 nærmere ved hjælp af de i figurerne viste udførelseseksempler.For a better understanding of the invention, this will be explained in greater detail by means of the exemplary embodiments shown in the figures.

First

Indledningsvis skal det fastholdes, at de samme dele forsynes med de samme henvisningstal respektive de samme konstruktionsdelbetegnelser i de forskelligt beskrevne udførelsesformer, idet de i den samlede beskrivelse anførte fremlæggelser kan overføres fornuftigt til samme dele med samme henvisningstal respektive samme konstruktionsdelbetegnelser. Ligeledes refererer de angivelser af beliggenhed, der er valgt i beskrivelsen, såsom f.eks. foroven, forneden, ved siden af osv., til den umiddelbart beskrevne samt viste figur og skal ved en ændring af beliggenhed overføres fornuftigt til den nye beliggenhed.Initially, it is to be noted that the same parts are provided with the same reference numerals or the same structural sub-designations in the various described embodiments, since the submissions stated in the overall description can be sensibly transferred to the same parts with the same reference numerals or the same structural partial designations. Also, the indications of location selected in the description, such as e.g. above, below, next to, etc., to the immediately described and shown figure and, in a change of location, must be sensibly transferred to the new location.

I fig. 1 til 4 er vist en sikringsindretning 1 med en sikringspåsætning 2 og et betjeningsmiddel 4, som kan forbindes med sikringspåsætningen 2 med henblik på en indstillingsbevægelse af en indstillingsspindel 3 til et ikke yderligere vist afspærringsarmatur.In FIG. Figures 1 to 4 show a securing device 1 with a securing attachment 2 and an operating means 4 which can be connected to the securing attachment 2 for adjusting movement of an adjusting spindle 3 to a locking fixture not shown further.

Sikringspåsætningen 2 er i det viste udførelseseksempel udformet i to dele, bestående af en cylinderformet kernedel 5 og en rørformet påsætningskappe 6. Påsætningskappen 6 er på den ene side udført afsluttet med en endeskive 4 DK 2008 00177 U4 7, som dækker over kernedelen 5 ved en endeflade, som vender bort fra indstillingsspindelen 3.In the illustrated embodiment, the fuse attachment 2 is formed in two parts, consisting of a cylindrical core part 5 and a tubular attachment cover 6. The attachment cover 6 is on one side completed with an end disc 4 which covers the core part 5 by a end face facing away from the adjusting spindle 3.

Kernedelen 5 har koncentrisk i forhold til en midterakse 8 en konisk indvendig optagelse 9 for en konustap 10 af indstillingsspindelen 3. Konustappen 10 er almindeligvis en 4-kant-tap, på hvilken sikringspåsætningens 2 kernedel 5 holdes fastsiddende under pres. Fortrinsvis er der i den indvendige optagelse 9 indpresset en sekskantmøtrik 11 med et gevind 12, som er orienteret koncentrisk i forhold til midteraksen 8. Således kan kernedelen 5 løsnes efter behov efter en aftagning af endeskiven 7 fra konustappen 10 ved hjælp af en ikke yderligere vist indstillingsskrue igennem en boring 13. Til aftagning af endeskiven 7 er der tilvejebragt en brydningskærv 14 mellem endeskiven 5 og en hylsterformet kappedel 15 af påsætningskappen 6.The core portion 5 has concentric relative to a center axis 8 a tapered inner receptacle 9 for a cone pin 10 of the adjusting spindle 3. The cone pin 10 is generally a 4-edge pin on which the core portion 5 of the securing attachment 2 is held under pressure. Preferably, in the inner recess 9, a hexagon nut 11 is pressed with a thread 12 oriented concentrically with respect to the center axis 8. Thus, the core portion 5 can be loosened as required after removing the end disc 7 from the taper pin 10 by means of a not shown further. adjusting screw through a bore 13. For removal of the end disk 7, a breaking groove 14 is provided between the end disk 5 and a casing-shaped sheath portion 15 of the attachment sheath 6.

Kernedelen 5 samt den hylsterformede kappedel 15 med endeskiven 7, som dækker over en endeflade 16 af kernedelen 5, er fortrinsvis fremstillet som en sprøjtestøbt del af plast.The core portion 5 as well as the casing-shaped sheath portion 15 with the end disk 7, which covers an end surface 16 of the core portion 5, are preferably manufactured as an injection molded portion of plastic.

Påsætningskappen 6 omgiver sammen med endeskiven 7 og den rørformede kappedel 15 kernedelen 5 og er, på et endeområde 18 modsat endeskiven 7, via en tilbageholdelsesring 17 fastholdt sikkert imod en aftrækning på kernedelen 5.The attachment sheath 6, together with the end disk 7 and the tubular sheath portion 15, surrounds the core part 5 and, on an end region 18 opposite the end disk 7, is securely secured via a retaining ring 17 against a pull on the core part 5.

Tilbageholdelsesringen 17 rager på en vulstlignende måde ud over en indvendig diameter 19 af påsætningskappen 6 i midteraksens 8 retning og overlapper ringformet en endeflade 20 af kernedelen 5 således, at en diameter 21 af en gennemgangsboring 22 i tilbageholdelsesringen 17 er lidt mindre end en udvendig diameter 23 af påsætningskappen 6.The retaining ring 17 projects in a bead-like manner beyond an inner diameter 19 of the attachment sheath 6 in the direction of the center axis 8 and overlaps an annular surface 20 of the core member 5 such that a diameter 21 of a through-bore 22 in the retaining ring 17 is slightly smaller than an outer diameter 23 of the cover 6.

5 DK 2008 00177 U4 Påsætningskappen 6 er lejret drejeligt på kernedelen 5 som følge af en fri-gangspasning mellem påsætningskappens 6 indvendige diameter 19 og kernedelens 5 udvendige diameter 23.The attachment sheath 6 is pivotally mounted on the core part 5 as a result of a clearance between the inner diameter 19 of the attachment sheath 6 and the outer diameter 23 of the core part 5.

5 En indvendig afstand 24 mellem endeskiven 7 og den vulstformede tilbageholdelsesring 17 er lidt større end en højde 25 af kernedelen 5.An internal distance 24 between the end disk 7 and the bead-shaped retaining ring 17 is slightly greater than a height 25 of the core portion 5.

Påsætningskappen 6 monteres med henblik på en montage på kernedelen 5 ved hjælp af en pressekraft i aksial retning, hvorved kappedelen 15 med den 10 vulstformede tilbageholdelsesring 17 udvides i kraft af en elastisk deforme-ring. Kernedelen 5 har i endefladens 16 område en afskråning af den udvendige diameter 23, hvorved hhv. påsætningsprocessen og den nødvendige elastiske udvidelse af tilbageholdelsesringen 17 gøres lettere. En tilbage-fjedring af kappedelen 15 bevirker så, at kernedelens 5 endeflade 20 griber 15 bagom, og at påsætningskappen 6 fastholdes sikkert aksialt.The attachment sheath 6 is mounted for mounting on the core part 5 by means of a compressive force in the axial direction, whereby the sheath part 15 with the 10 bead-shaped retaining ring 17 is extended by virtue of an elastic deformation. In the region of the end surface 16, the core member 5 has an inclination of the outer diameter 23, whereby respectively. the attachment process and the necessary elastic extension of the retaining ring 17 are facilitated. A resilience of the cap portion 15 then causes the end surface 20 of the core portion 5 to engage 15 and the attachment cap 6 to be securely secured axially.

Ifølge en mulig videreudvikling har påsætningskappen 6, således som det er vist med punkterede linjer, i forlængelse af den rørformede kappedel 15 en halsring, som er udformet ud i et, og som eksempelvis tjener til at dække et 20 eventuelt dertil tiltænkt forbindelsesmiddel, f.eks. en skrue til fastgørelse af en konuspåsætning.According to a possible further development, as shown with dashed lines, the attachment sheath 6 has, in extension of the tubular sheath portion 15, a neck ring formed in one, which serves, for example, to cover any possible connecting means, f. eg. a screw for securing a cone attachment.

Kernedelens højde 25 er større end en længde 26 af konustappen 10 plus en møtrikhøjde 27 og en overdækningshøjde 28, som har boringen 13.The core portion height 25 is greater than a length 26 of the cone pin 10 plus a nut height 27 and a cover height 28 having bore 13.

Som det fremgår mere tydeligt af fig. 2 til 4, er der i kernedelen 5 ifølge dette viste udførelseseksempel tilvejebragt fire slidsformede noter 29, som er fordelt ensartet over en omkreds, og som strækker sig over den samlede højde 25 og er orienteret parallelt med midteraksen 8 i en delingsvinkel på 90°. 30 Disse dannes af boringer 31, som er anbragt på en midtercirkel 30, som forløber koncentrisk i forhold til midteraksen 8, og som er åbnet ved hjælp af 6 DK 2008 00177 U4 omtrent parallelle sideflader 33 svarende til en diameter 32 i retning af den udvendige omkreds. Disse danner sammenkoblingsoptagelser 34 i kernedelen 5 til brug for en påsætning af betjeningsmidlet 4 med henblik på en kraftoverføring til indstillingsspindelen 3.As can be seen more clearly in FIG. 2 to 4, in the core portion 5 of this exemplary embodiment, four slotted grooves 29 are provided which are distributed uniformly over a circumference and extend over the overall height 25 and are oriented parallel to the center axis 8 at a 90 ° pitch angle. These are formed by bores 31 arranged on a center circle 30 which extend concentrically with respect to the center axis 8 and which are opened by means of approximately parallel side surfaces 33 corresponding to a diameter 32 in the direction of the outside. circumference. These form coupling receptacles 34 in the core portion 5 for use of applying the actuating means 4 for a power transmission to the adjusting spindle 3.

En midtercirkeldiameter 35 er lidt mindre end kernedelens 5 udvendige diameter 23 minus to gange diameteren 32 af boringerne 31 i sammenkoblingsoptagelserne 34.A center circle diameter 35 is slightly smaller than the outside diameter 23 of the core part 5 minus twice the diameter 32 of the bores 31 in the interconnection recesses 34.

Som det yderligere fremgår af fig. 4, er der i påsætningskappens 6 endeskive 7 ligeledes på omtrent den samme midtercirkel 30 med midtercirkeldiamete-ren 35 og ligeledes i en vinkeldeling på 90° tilvejebragt fire gennemgangsboringer 36 som yderligere sammenkoblingsoptagelser 37 med en diameter 38, som omtrent svarer til diameteren 32 i noternes 29 boringer 31.As further shown in FIG. 4, in about the same center circle 30 with the center circle diameter 35 and in a 90 ° angular pitch, four through bores 36 are also provided in the end disc 7 of the clamping cap 6 as additional connecting holes 37 with a diameter 38 approximately corresponding to the diameter 32 in the grooves. 29 bores 31.

Betjeningsmidlet 4 udformes, således som det yderligere fremgår især af fig. 1, af en skiveformet basisdel 39 og eksempelvis ligeledes en konustap 40, som er anbragt koncentrisk i forhold til midteraksen 8.The operating means 4 are designed, as is further apparent in particular from FIG. 1, of a disc-shaped base portion 39 and, for example, also a cone pin 40, which is arranged concentrically with respect to the center axis 8.

Basisdelen 39 har sammenkoblingsmidler 43, som rager ud over en i forhold til konustappen 40 modstillet endeflade 41, og som er udformet af cylinderstifter 42, og som er anbragt i delingsvinklen 90° ligeledes på midtercirklen 30 med midtercirkeldiameteren 35, og midterakser 44 er orienteret parallelt med midteraksen 8.The base member 39 has coupling means 43 which project beyond an end face 41 which is opposed to the taper pin 40 and which is formed by cylinder pins 42, which are also located at the 90 ° pitch angle on the center circle 30 with the center circle diameter 35, and the center axes 44 are oriented in parallel. with the center axis 8.

En diameter 45 af cylinderstifterne 42 er lidt mindre end diameteren 38 af gennemgangsboringerne 36 i endeskiven 7 og noternes 29 boringer 31.A diameter 45 of the cylinder pins 42 is slightly smaller than the diameter 38 of the through bores 36 of the end disk 7 and the bores 31 of the grooves 29.

Cylinderstifterne 42 rager ud over endefladen 41 af den skiveformede basisdel 39 og rager efter påsætningen af sammenkoblingspåsætningen 42 på 7 DK 2008 00177 U4 endeskiven 7 ind igennem gennemgangsboringerne 36 og ud over en del af højden 25 i kernedelens 5 sammenkoblingsoptagelser 34.Cylinder pins 42 protrude beyond the end face 41 of disc-shaped base portion 39 and protrude after application of the interconnect application 42 on the end disc 7 through the through bores 36 and beyond a portion of the height 25 of the interconnect receptacles 34 of the core portion 5.

Dermed bliver der mulighed for en formsluttende forbindelse mellem betjeningsmidlet 4 og kernedelen 12, som er anbragt på indstillingsspindelens konustap 10, og det bliver dermed muligt at betjene indstillingsspindelen 3.This allows for a form-fitting connection between the operating means 4 and the core part 12, which is arranged on the adjusting spindle 10's cone pin, thus making it possible to operate the adjusting spindle 3.

Når betjeningsmidlet 4 sammenkobles, dvs. når sammenkoblingsmidlerne 43 bringes i indgreb med kernedelens 5 sammenkoblingsoptagelser 34 for at foretage en indstilling af indstillingsspindelen 3, kræves der dog en positionering af den drejelige påsætningskappe 6 med henblik på at bringe kernedelens 5 og påsætningskappens 6 sammenkoblingsoptagelser 34, 37 i et kongruent niveau.When the operating means 4 are connected, i. however, when the coupling means 43 are engaged with the coupling apertures 34 of the core member 5 to adjust the adjusting spindle 3, however, positioning of the pivotal mounting sheath 6 is required to bring the coupling apertures 34, 37 of the core part 5 and the coupling cap 6 into a congruent level.

På grund af påsætningskappens 6 drejelige placering på kernedelen 5 samt dens cylindriske udformning med glat væg samt sammenkoblingsoptagelsernes 34, 37 og sammenkoblingsmidlemes 43 placering og udformning er det nærmest udelukket, at en uberettiget og skadelig manipulation udøvet af ubeføjede personer, som ikke råder over det tilsvarende udformede betjeningsmiddel 4, kan finde sted.Due to the pivotal position of the attachment sheath 6 on the core part 5 and its cylindrical smooth wall configuration as well as the location and configuration of the interconnecting recesses 34, 37 and the interconnecting means 43, it is virtually excluded that unjustified and harmful manipulation by unauthorized persons who do not possess the corresponding designed actuator 4 may take place.

I stedet for konustappen 40 er der naturligvis også mulighed for andre former for et håndtag, f.eks. en T-stang, ved hjælp af hvilken der kan udøves en dre-jebevægelse på kernedelen 5 efter påsætningen af betjeningsmidlet 4 på sikringspåsætningen 2.Of course, instead of the cone pin 40, other forms of a handle, e.g. a T-bar by means of which a pivotal movement can be exerted on the core portion 5 after the application of the operating means 4 to the securing application 2.

I det viste udførelseseksempel er sammenkoblingsoptagelseme 34, 37 og sammenkoblingsmidleme 43 ved omkredsen 30 med omkredsdiameteren 35 ifølge en foretrukket udførelsesform anbragt i en afstand fra hinanden i en centrumsvinkel 46 på 90°. Selvfølgelig er der også mulighed for en anden DK 2008 00177 U4 8 lignende placering, f.eks. 45°, 60° eller 120°, ligesom der dog også er mulighed for en uregelmæssig vinkeldeling.In the illustrated embodiment, the coupling receptacles 34, 37 and the coupling means 43, at the circumference 30, with the circumferential diameter 35, according to a preferred embodiment, are spaced apart at a center angle 46 of 90 °. Of course, there is also the possibility of another DK 2008 00177 U4 8 similar location, e.g. 45 °, 60 ° or 120 °, as well as an irregular angle distribution.

For en god ordens skyld skal der afslutningsvis henvises til, at sikringsindret-5 ningen og dennes bestanddele med henblik på en bedre forståelse af sikringsindretningens opbygning delvist ikke er vist i målestok og/eller er vist forstørret og/eller formindsket.Finally, for the sake of good order, it should be noted that, for a better understanding of the structure of the fuse, the fuse and its components are not partially scaled and / or shown enlarged and / or diminished.

Den opgave, som de uafhængige opfindelsesmæssige løsninger er baseret 10 på, fremgår af beskrivelsen.The task on which the independent inventive solutions are based is apparent from the description.
