Description

Opfindelsen angår en belysningsramme som angivet 1 indledningen til krav 1 samt forbindelseselementer til dens fastholdelse.The invention relates to a lighting frame as set forth in the preamble of claim 1 as well as connecting elements for its retention.

Ved belysningsramme forstås her en firkantet ram-5 me med konstant højde, som begrænser en nedre og eventuelt en øvre rammeåbning og tjener til afskærmning af lamper, som er anbragt i belysningsrammen. I rammeåbningerne kan der yderligere være anbragt lysstyrende og/el-ler afskærmende elementer såsom rastere, prismeplader og 10 lignende.By lighting frame is here meant a square frame of constant height which limits a lower and possibly an upper frame opening and serves to shield lamps placed in the lighting frame. Light-guiding and / or shielding elements such as grids, prism plates and the like may be further arranged in the frame openings.

Ofte har de vinkelret på hinanden forløbende rammedele i en sådan belysningsramme ens profiler, og de sammenholdes ved hjælp af hjørneforbindelsesled med tilpasset profil, hvorhos rammedelene stikkes ind på kob-15 lingsarme på hjørneforbindelsesleddet og eksempelvis fikseres med klemskruer. Eksempler på sådanne hjørneforbindelsesled er beskrevet i DE-A-30 41 111 eller DE-A- 2 645 767.Often, the perpendicularly extending frame members in such an illumination frame have similar profiles, and are held together by means of custom profile corner joints, the frame members being inserted into coupling arms of the corner joint and, for example, being fixed by clamping screws. Examples of such corner joints are described in DE-A-30 41 111 or DE-A-2 645 767.

Hvis belysninger med sådanne belysningsrammer 20 skal anordnes i form af lysbånd og/eller figurer, eksempelvis med stjerneformet knudepunkt, kræves der til forbindelse af de enkelte belysningsrammer for hver konfiguration specielle forbindelsesdele og tilsvarende tilpassede rammedele, som kan fastgøres dertil. Det sam-25 me gælder, hvis der på en sådan belysningsramme skal påsættes andre komponentgrupper, eksempelvis kabinetter til højttalere eller en belysningsbærer til opstilling af belysningen.If illuminations with such illumination frames 20 are to be arranged in the form of strips of light and / or figures, for example with a star-shaped node, special connection parts and correspondingly adapted frame parts may be required for each configuration for each configuration. The same applies if other component groups are to be fitted to such a lighting frame, such as speakers cabinets or a lighting carrier for setting up the lighting.

Ved opfindelsen tilsigtes tilvejebragt en belys-30 ningsramme af den indledningsvis omhandlede art, ved hvilken der praktisk taget ikke kræves nogen ændring af den til enkeltvis anvendelse egnede belysningsramme, hvis denne skal forbindes med yderligere belysningsrammer eller andre komponentgrupper. Navnlig skal en sik-35 ker gennemgående elektrisk trådføring være mulig.The invention is intended to provide an illumination frame of the kind initially referred to, in which virtually no alteration of the single-use illumination frame is required if it is to be connected to additional illumination frames or other component groups. In particular, a more secure electrical wiring must be possible.

Løsningen ifølge opfindelsen på denne opgave er karakteriseret ved midler angivet i krav 11 s kendetegnende del.The solution according to the invention to this task is characterized by means as defined in claim 11 s.

Profilen af belysningsrammens rammedele - og dermed profilen af det tilhørende hjørneforbindelsesled -er valgt således, at hjørneforbindelsesleddet kan udføres med brede montagevægge, på hvilke et forbindelses-5 element til forbindelse af belysningsrammen med en anden eller med en komponentgruppe kan fastgøres. Samtidigt får de fortrinsvis på en formningsvalsegade fremstillede rammedele en meget høj stabilitet. Denne forøges yderligere ved hjælp af to foroven og forneden indefter ombuk-10 kede montagerande, som samtidigt gør det muligt at fastskrue rammedelene på hjørneforbindelsesleddene og på rammedelene at fastgøre belysningstilbehør, uden at dette viser synlige spor udvendigt på belysningsrammen.The profile of the frame of the lighting frame - and thus the profile of the associated corner joints - is selected so that the corner joint can be formed with wide mounting walls on which a connecting member for connecting the lighting frame with another or with a component group can be attached. At the same time, the frame parts made on a forming roller street preferably have a very high stability. This is further increased by means of two upper and lower folded mounting edges, which at the same time allow the frame parts to be fastened to the corner connection joints and to the frame parts to attach lighting accessories without showing visible traces on the outside of the lighting frame.

De koblingsarme på et hjørneforbindelsesled, som 15 griber ind i de rammedele, der skal forbindes, har hver især en stopribbe, mod hvilken rammedelenes snitkanter ligger an og derved skjules, og som mellem sig begrænser et mellemstykke med mindst én montageflade, hvorpå der enten kan fastgøres et forbindelseselement eller en 20 hjørneafskærmning. Fortrinsvis ligger stopribberne og dermed rammedelenes snitkanter i to på hinanden og på rammeåbningen vinkelret stående planer; dermed har mellem stopribberne beliggende montagevægge på mellemstykket i det væsentlige form som en ligebenet retvink-25 let trekant.The coupling arms of a corner connecting joint which engage the frame parts to be connected each have a stop rib, against which the cut edges of the frame parts abut and thereby conceal, and which between them limit an intermediate piece with at least one mounting surface on which either a connecting member or a corner guard is attached. Preferably, the stop ribs, and thus the cut edges of the frame members, lie in two planes perpendicular to each other and on the frame opening; thus, the mounting walls located between the stop ribs have essentially the shape of a straight-legged rectangular triangle.

På hver montagevæg på et hjørneforbindelsesleds mellemstykke kan der nu være fastgjort et forbindelseselement med en halvarm, som hertil har et trekantet bærestykke, der netop passer på en montagevægs montagefla-30 de og kan skrues sammen med denne. I øvrigt kan forbindelseselementet - alt efter udformningen i det enkelte tilfælde - være udført forskelligt: Ved belysningsrammens fastgørelse på en belysningsbærer kan halvarmen allerede være en del af denne belysningsbærer.On each mounting wall of a corner connection joint, there can now be attached a half-arm connecting element, which has a triangular support piece which fits precisely on the mounting surface of a mounting wall and can be screwed together with it. In addition, the connecting element - depending on the design in each case - may have been designed differently: When attaching the lighting frame to a lighting carrier, the half-arm may already be part of this lighting carrier.

35 Fortrinsvis består forbindelseselementet af to i forhold til et tværgående plan symmetriske halvarme, så- 3Preferably, the connecting element consists of two transverse plane symmetrical half-arms, such that 3

ledes at der dermed muliggøres en forbindelse af to belysningsrammer fra hjørneforbindelsesled til hjørneforbindelsesled. Vinklen mellem det lodrette midterplan på det trekantede bærestykke og det tværgående plan er der-5 ved lig med delevinklen mellem de to på denne måde med hinanden forbundne belysningsrammers akser.is guided, thereby enabling a connection of two lighting frames from corner connector to corner connector. The angle between the vertical center plane of the triangular support and the transverse plane is therefore equal to the angle of division between the two axes of the illumination frames interconnected in this way.

Til de hyppigst forekommende forbindelser mellem belysningsrammer - 90° og 180° - findes der fortrinsvis faste forbindelsesstykker; det mellemliggende vinkelom-10 råde dækkes af et forbindelsesstykke med to hængselforbundne ledarme.For the most frequent connections between lighting frames - 90 ° and 180 ° - there are preferably fixed connectors; the intermediate angular region is covered by a connecting piece with two hinged link arms.

Fortrinsvis omslutter forbindelsesstykket med yderligere vægdele en ledningskanal mellem de belysningsrammer, der skal forbindes med hinanden. Mod denne 15 ledningskanal vender på hjørneforbindelsesleddets side en gennemgangsåbning i mellemstykket.Preferably, the connector with additional wall portions encloses a conduit between the lighting frames to be interconnected. Towards this 15 conduit channel, on the side of the corner connector, a passage opening in the spacer faces.

Med henblik på at lette montagen og navnlig trådføringen mellem med hinanden forbundne belysninger består hvert forbindelseselement fortrinsvis af en øvre og 20 en nedre bæredel med vægdele, som i hvert enkelt tilfælde kun omslutter ledningskanalen i sideretningen til ca. den halve højde: På denne måde er det eksempelvis muligt først at forbinde to nabobelysningsrammer med hinanden over den nedre bæredel, derefter at indlægge den elek-25 triske trådføring og sluttelig at lukke kanalen ved hjælp af den øvre bæredel, som da også yderligere stabiliserer forbindelsen mellem de to belysningsrammer mekanisk. Fortrinsvis er hvert "halve" forbindelseselement, navnlig i området ved vægdelenes rande, udformet såle-30 des, at et komplet forbindelseselement kan sammensættes af to ens "halve" forbindelseselementer.In order to facilitate mounting and in particular the wiring between interconnected lighting, each connecting element preferably consists of an upper and a lower support part with wall parts, which in each case only encloses the duct in the lateral direction to approx. half height: In this way, for example, it is possible, for example, to first connect two adjacent lighting frames over the lower support part, then to insert the electric wire guide and finally to close the channel by means of the upper support part, which then further stabilizes the connection. between the two lighting frames mechanically. Preferably, each "half" connecting member, especially in the region at the edges of the wall portions, is designed so that a complete connecting member may be composed of two identical "half" connecting members.

Yderligere udformninger af opfindelsen er karakteriseret i underkravene.Further embodiments of the invention are characterized in the subclaims.

5 rerne 5-10, gør det på enkel måde muligt ved hjælp af et forbindelseselement 3 at koble to belysningsrammer med hinanden over deres hjørneforbindelsesled, sådan som det eksempelvis fremgår af figurerne 2-4.5, 5-10, in a simple manner, it is possible to connect two lighting frames with one another via their connecting elements 3 over their corner connecting links, as can be seen, for example, in Figures 2-4.

5 I fig. 2 er der anvendt et forbindelseselement for en delevinkel α på 90° mellem belysningsrammerne l's længdeakser; et sådant forbindelseselement er vist mere detaljeret i figurerne 11-13.5 In FIG. 2, a connecting element for a 90 ° divider angle is used between the longitudinal axes of the lighting frames 1; such a connecting element is shown in more detail in Figures 11-13.

Fig. 3 viser en opstilling med to belysningsram-10 mer 1 med en delevinkel på 0° henholdsvis 180° (lysbånd). De to belysningsrammer 1 er her koblet med hinanden ved to nabohjørner over to ens forbindelseselementer 3.1.FIG. 3 shows an arrangement of two illumination frames 1 with a pitch angle of 0 ° and 180 ° (light band) respectively. The two lighting frames 1 are here interconnected at two neighboring corners over two identical connecting elements 3.1.

I den i fig. 4 viste opstilling danner seks be-15 lysningsrammer 1 et knudepunkt, hvor delevinklen α mellem nabobelysningsrammer andrager 60°· To nab°belys-ningsrammer 1 er her koblet med hinanden ved hjælp af et forbindelseselement 3.2, som har to hængselforbundne ledarme (jf. figurerne 14-17).In the embodiment shown in FIG. 4, six illumination frames 1 form a junction where the divider angle α between adjacent illumination frames is 60 ° · Two adjacent illumination frames 1 are here interconnected by means of a connecting element 3.2 having two hinged link arms (cf. Figs. 14-17).

2o Det i fig. 5 viste hjørneforbindelsesled er et støbt emne med to ens koblingsarme 20, der med hinanden indeslutter en ret vinkel, og mellem hvilke der ligger et mellemstykke 21, som ved hjælp af stopribber 200 er afgrænset i forhold til koblingsarmene 20. Kob-25 lingsarmene 20 har ens profiler med et hovedben 201, to på tværs deraf forløbende tværgående ben 2021 og i tilslutning til disse opefter og nedefter lodrette ben 2022, som går over i et randben 203, der har en udboring 2030.2o The embodiment of FIG. 5 is a molded workpiece with two identical coupling arms 20 which intersect at a right angle, and between which there is an intermediate piece 21 which is defined by means of stop ribs 200 relative to the coupling arms 20. The coupling arms 20 have similar profiles having a head bone 201, two transverse legs 2021 extending transversely thereof, and adjacent to these up and down vertical legs 2022, passing into an edge leg 203 having a bore 2030.

30 Mellemstykket 21 mellem de to koblingsarme 20 udgøres navnlig af to montagevægge 210, som tilnærmelsesvis forløber i de tværgående ben 2021's plan, og som hver har en montageudboring 2102. Den udvendige overflade på disse montagevægge er betegnet med 2101.In particular, the intermediate piece 21 between the two coupling arms 20 is constituted by two mounting walls 210, which extend approximately in the plane of the transverse legs 2021, each having a mounting bore 2102. The outer surface of these mounting walls is designated 2101.

35 Mellem montagevæggene 210 ligger der en firkantet gennemgangsåbning 22.Between the mounting walls 210 there is a square passage 22.

den belysningsramme eller en anden komponent, kan hjørneforbindelsesleddets mellemstykke 21 dækkes med en i fig. 5.1 vist hjørneafskærmning med en dækarm 35. Denne grænser flugtende op til de to stopribber 200. Når 5 der på koblingsarmene 20 er påstukket rammedele, bliver de ved hjælp af denne hjørneafskærmning forbundet optisk med hinanden med en tilpasset radius.the illumination frame or other component, the corner connector 21 of the corner connector can be covered with a one in FIG. 5.1, a corner shield is shown with a cover arm 35. This adjoins the two stop ribs 200. When frame members are mounted on the coupling arms 20, by means of this corner shield, they are connected optically to one another with an adapted radius.

I de i figurerne 7 og 8 viste snitbilleder af hjørneforbindelsesleddet er der indtegnet afsnit af en 10 påsat rammedel 10: fig. 7 viser således, hvordan rammedelen 10 ved hjælp af en montagebenet 104 gennemtrængende skrue er fastgjort på randbenet 203. Fig. 8 viser, hvordan rammedelen 10's snitkant 100 ligger an mod stopribben 200.In the sectional views of the corner connecting link shown in Figures 7 and 8, sections of a frame part 10 affixed to it are shown: FIG. 7 thus shows how the frame part 10 is secured by means of a mounting leg 104 penetrating screw to the rim leg 203. FIG. 8 shows how the cut edge 100 of the frame member 10 abuts the stop rib 200.

15 En sådan rammedel er i fig. 9 vist i et indven digt billede (i retning af pilen IX i fig. 10) og i fig. 10 i et snitbillede (langs linien X-X). Denne rammedels profil er bestemt ved hjørneforbindelsesleddet 2's profil og har en hovedvæg 101, to tilnærmet vin-20 kelret på denne forløbende tværgående vægge 1021 og i tilslutning dertil lodrette vægge 1022, som forløber tilnærmet parallelt med hovedvæggen og danner forbindelsen til to L-formede montagerande 103 med indad ombukkede montageben 104. De sidstnævnte har udboringer 25 1040, som gør det muligt at fastgøre en sådan rammedel på hjørneforbindelsesleddets randben 203 indefra, uden at dette er synligt ude fra (jf. fig. 7).15 Such a frame member is shown in FIG. 9 is shown in an internal view (in the direction of arrow IX in FIG. 10) and in FIG. 10 in a sectional view (along line X-X). The profile of this frame member is determined by the profile of the corner connector 2 and has a main wall 101, two approximately perpendicular to this extending transverse wall 1021 and adjacent vertical walls 1022 extending approximately parallel to the main wall and forming the connection to two L-shaped mounting edges. 103 with inwardly folded mounting legs 104. The latter have bores 25 1040 which allow such a frame member to be secured to the corner leg 203 from the corner connection joint without being visible from the outside (cf. Fig. 7).

Den L-formede montagerand 103 danner sammen med den lodrette væg 1022 en U-formet rende 105, som 30 forøger rammedelens stabilitet, og som skaber en enkel mulighed for fastgørelse af en montagebøjle på rammedelen: Hertil bliver en sådan montagebøjle med en fod stukket ind i den nedre rende på rammedelen og fastskruet på den overfor beliggende rendes montageben 104.The L-shaped mounting bracket 103 together with the vertical wall 1022 forms a U-shaped trough 105 which increases the stability of the frame part and which provides a simple possibility of attaching a mounting bracket to the frame part: For this, such a mounting bracket with a foot is inserted in the lower gutter of the frame part and screwed onto the mounting leg 104 of the opposite gutter.

35 Sådanne montagebøjler kan tjene til fastholdelse af belysningstilbehør såsom fatninger, hjælpeapparatur etc., DK 16 Π 0 'i R Β 7 som enten kan være anbragt på ydersiden - vendende mod belysningsrummet - og/eller på indersiden - vendende mod rammedelens hovedvæg 101.35 Such mounting brackets can serve to hold lighting accessories such as sockets, auxiliary equipment, etc., DK 16 Π 0 'in R Β 7 which can either be mounted on the outside - facing the lighting room - and / or on the inside - facing the main wall 101.

Form og dimensioner af rammedelens profil er be-5 stemt ved en indskrevet grundfirkant 110, som med en af sine længdesider h ligger i et grænseplan E, som forløber mellem de to montageben 104. Bredden b af denne grundfirkant er lig med eller større end dens halve højde h og fortrinsvis 20% mindre end denne højde 10 h: rammedelene har således en fra det kendte tydeligt afvigende, nemlig en væsentligt større bredde b, som dels muliggør hjørneforbindelsesled med et tilstrækkeligt stort mellemstykke, dels muliggør anbringelse af tilbehør.The shape and dimensions of the frame member profile are determined by an inscribed basic square 110 which, with one of its longitudinal sides h, lies in a boundary plane E extending between the two mounting legs 104. The width b of this basic square is equal to or greater than its half the height h and preferably 20% less than this height 10 h: the frame members thus have a deviation from the known, namely a substantially larger width b, which partly enables corner joints with a sufficiently large intermediate part and partly allows the placement of accessories.

15 Med henvisning til figurerne 11-13 forklares det i fig. 2 viste forbindelseselement 3 i detaljer: Ifølge fig. 11 består det af to ens, i forhold til tværplanet Q symmetriske bæredele 34, hvorhos den nederste del i sammenligning med den øverste del blot er drejet 20 180° om sin længdeakse L. En sådan bæredel 34 har ved hver af sine to ender et bærestykke 32 med trekantet form, hvorhos randkanterne 320 indeslutter en ret vinkel. Disse bærestykker 32 har endvidere en udboring 33 og er dimensioneret således, at de netop passer mel-25 lem stopribberne 200 på forbindelseselementet 2's mellemstykke 21 og ligger an på montagevæggen 210's udvendige overflade, hvorhos udboringerne 33, 2102 i bærestykket 32 henholdsvis i montagevæggen 210 flugter, således at bæredelen 34 kan fastgøres udrejeligt 30 med en gennem disse boringer ført skrue.With reference to Figures 11-13, it is explained in Figs. 2 in detail: According to FIG. 11, it consists of two identical, symmetrical support members 34 with respect to the transverse plane Q, the lower part of which, in comparison with the upper part, is simply rotated 180 ° about its longitudinal axis L. Such a support part 34 has a support piece at each of its two ends. 32 with a triangular shape, the rim edges 320 enclosing a right angle. These supports 32 also have a bore 33 and are dimensioned to fit precisely between the stop ribs 200 on the connecting piece 2 of the connecting element 2 and abut on the outer surface of the mounting wall 210, the bores 33, 2102 in the support 32 and in the wall 210 respectively aligning so that the support member 34 can be removably fastened 30 with a screw passed through these bores.

I tilslutning til de to ender på hver bæredel findes der opefter og nedefter en afskærmningsarm 35, som dækker hjørneforbindelsesleddet 2's mellemstykke 21 i området for dets randben 203 og dets lodrette 35 ben 2022; den svarer til hjørneafdækningens afskærmningsarm 35 som vist i fig. 5.1 med hensyn til form og funktion.Adjacent to the two ends of each support portion there is up and down a shielding arm 35 which covers the interconnector 21 of the corner connecting link 2 in the region of its rim legs 203 and its vertical legs 2022; it corresponds to the corner cover arm 35 as shown in FIG. 5.1 in terms of form and function.

Fra hver bæredel 34 rager to vægdele 301, 302 ud i samme retning, hvilke vægdele har komplementært udformede rande 3010, 3020. Længden af disse vægdele og udformningen af disse rande er valgt således, at vægde-5 lene ved fuldstændigt sammenstukne bæredele overlapper hinanden og derved lader en synlig not forblive fri, som forløber i samme højde hele vejen. De to bæredele 34 er i figurerne 11 og 13 tegnet med nogen indbyrdes afstand med henblik på tydeligt at vise udformningen af 10 disse rande.From each support member 34, two wall portions 301, 302 project in the same direction, which wall portions have complementary shaped edges 3010, 3020. The length of these wall portions and the configuration of these edges are selected such that the wall portions overlap fully supported portions and thereby leaving a visible groove free, which runs at the same height all the way. The two supporting parts 34 are shown in Figures 11 and 13 with some spacing in order to clearly show the shape of these edges.

Figurerne 14-17 viser sluttelig detaljeret det i fig. 4 skematisk viste forbindelseselement 3.2. Det omfatter her to med hinanden hængselforbundne ledarme 3.20, der igen er udført ens: Den højre halvarm i fig.Figures 14-17 finally show in detail that in Figs. 4 schematically shown connection element 3.2. It comprises here two two hinged link arms 3.20, which in turn are identical: The right half-arm in fig.

15 14 er i sammenligning med den venstre blot drejet 180° om en vinkelret på tegningsplanet stående akse.In comparison with the left one, 14 14 is rotated 180 ° about an axis perpendicular to the drawing plane.

Hver ledarm 3.20 består af to halvarme, nemlig en øvre halvarm 34.1 og en nedre halvarm 34.2. Halvarmene har ens udførte trekantede bærestykker 32 med 20 en udboring 33, som igen passer på den trekantede montagevæg 210 på et hjørneforbindelsesled 2. Et sådant hjørneforbindelsesled er indtegnet punkteret i den højre del af fig. 14. Deraf fremgår også skrueforbindelsen mellem montagevæggene 210 og halvarmene 34.1 hen- 25 holdsvis 34.2.Each articulated arm 3.20 consists of two half-arms, namely an upper half-arm 34.1 and a lower half-arm 34.2. The half-arms have similarly made triangular supports 32 with 20 a bore 33 which in turn fits on the triangular mounting wall 210 on a corner connection joint 2. Such a corner connection joint is plotted in the right part of FIG. 14. This also shows the screw connection between the mounting walls 210 and the half-arms 34.1 and 34.2, respectively.

Halvarmene har endvidere hver især ens afskærmningsarme 35, hvis funktion er den samme som i udførelseseksemplet i figurerne 11-13.Furthermore, the half-arms each have the same shielding arms 35, the function of which is the same as in the embodiment in figures 11-13.

Hver ledarm 34.1, 34.2 har et drejestykke 30 34.21, 34.22 med cirkelkontur; to halvarme 34.1 og 34.2 ligger med deres drejestykker 34.21 og 34.22 an mod hinanden, de er forbundet drejeligt med hinanden ved hjælp af en ledskrue 34.23 og danner således en bæredel. Drejestykket 34.22 på halvarmen 34.2 er 35 forskudt noget tilbage indefter i forhold til drejestykket 34.21 på halvarmen 34.1, således at de to med 9Each guide arm 34.1, 34.2 has a pivot piece 34.21, 34.22 with circular contour; two half-arms 34.1 and 34.2 with their pivots 34.21 and 34.22 abut each other, they are pivotally connected to each other by means of a joint screw 34.23 and thus form a supporting part. The turning piece 34.22 on the half-arm 34.2 is displaced slightly backwards relative to the turning piece 34.21 on the half-arm 34.1, so that the

Hver halvarm 34.1, 34.2 har på hver side væg- 5 dele 301.1 og 302.1, der tilsammen omslutter en ledningskanal. Denne er imidlertid i drejestykkernes område afbrudt af vinduer 300, som er lige store, når de to ledarme befinder sig i den i figurerne viste position, som navnlig fremgår tydeligt af fig. 15. Disse vinduer 10 er afdækket af vægsektorer 3.212 og 3.213 på en rotationscylinder 3.21, der i fig. 17 er vist i et sidebillede og i figurerne 14 og 16 blot er antydet punkteret med sine omrids. De to vægsektorer på denne rotationscylinder er - som det navnlig fremgår af fig. 15 -15 ulige store, hvorhos den mindste - 3.212 - netop er tilstrækkelig til at dække vinduesbredden i den i fig. 15 viste stilling (delevinkel α =90° ). Den anden væg sektor 3.213 er derimod så stor, at den også er tilstrækkelig til at dække det større vindue, når de to 20 ledarme 3.20 befinder sig i den mulige grænseposition, hvor endekanterne 301.11 og 302.11 på vægdelene 301 og 302 i fig. 15 støder mod hinanden. Såfremt den anden grænseposition indstilles, i hvilken de to andre endekanter støder mod hinanden, bliver rotationscylinderen 25 3.21 drejet 180° om sin midterakse S (fig. 17) og i denne drejede position indsat mellem ledarmenes dreje-dele.Each half arm 34.1, 34.2 has on each side wall portions 301.1 and 302.1 which together enclose a conduit. However, in the area of the pivots, this is interrupted by windows 300 which are equal when the two articulated arms are in the position shown in the figures, which is particularly evident in FIG. 15. These windows 10 are covered by wall sectors 3.212 and 3.213 on a rotary cylinder 3.21, which in FIG. 17 is shown in a side view and in Figures 14 and 16 is merely indicated by its outline. The two wall sectors of this rotary cylinder are - as can be seen in particular in FIG. 15 -15 odd sizes, the smallest of which - 3,212 - is just sufficient to cover the window width of the one shown in FIG. 15 (part angle α = 90 °). The second wall sector 3.213, on the other hand, is so large that it is also sufficient to cover the larger window when the two 20 guide arms 3.20 are in the possible boundary position, where the end edges 301.11 and 302.11 of the wall parts 301 and 302 in FIG. 15 bump into each other. If the second boundary position is set, in which the other two end edges abut, the rotary cylinder 25 3.21 is rotated 180 ° about its center axis S (Fig. 17) and inserted in this pivoted position between the pivot arms.

Rotationscylinderen 3.21 lukker således i enhver mulig drejestilling af ledarmene den mellem dem 30 forløbende ledningskanal 31, hvorhos denne ledningskanals gennemtrængelighed er sikret ved hjælp af passagerne 310 mellem rotationscylinderen 3.21's vægsektorer 3.212 og 3.213.Thus, in every possible pivoting position of the articulated arms, the rotary cylinder 3.21 closes the conductor 31 extending between them 30, the permeability of this conductor channel being secured by the passages 310 between the wall sectors 3.212 and 3.213 of the rotary cylinder 3.21.
