Description

Isocentrische, isometrische en orthotesseraal richtbare koppeling van zes buizen,Isocentric, isometric and orthotessalally orientable coupling of six tubes,

In het onderstaande wordt de kopse bevestiging beschreven van zes (of minder) buizen -eender van doorsnede, gericht op een gemeenschappelijk centrum M en op gelijke afstanden tot 5 hetzelve - aan een koppelstuk, dat een beperkte beweging van vier buizen toelaat, gelegen in een vlak loodrecht op een tweetal polair gerichte buizen. Bijgevolg is de koppeling dezer buizen dan ook isocentrisch, isometrisch en orthotesseraal richtbaar.The following describes the end-to-end attachment of six (or fewer) tubes - all of a cross-section, directed at a common center M and at equal distances up to 5 - to a coupling piece, which allows a limited movement of four tubes located in a flat perpendicular to two polar-oriented tubes. Consequently, the coupling of these tubes is also isocentric, isometric and orthotessally orientable.

Het koppelstuk en de buizen zijn vervaardigd van voldoende stevig en bestendig, dan wel oppervlakkig bestendig gemaakt, materiaal. Uitgebreide overspannende constructies m.b.v. zoveel 10 mogelijk gestandaardiseerde onderdelen, zijn hiermede snel en goedkoop te verwezelijken, bijvoorbeeld in de bouw.The coupling piece and the tubes are made of sufficiently strong and resistant, or made superficially resistant, material. Extensive spanning constructions using as many standardized components as possible can be realized quickly and cheaply, for example in construction.

De langs de polair gerichte hartlijn (draaiingslijn) p (zie de Fig.1 en Fig.2) bevestigde buizen zijn Pi en P2; de in het loodvlak op p richtbare paren van overstaande buizen zijn (T3, T4) resp. (Ts, Tö). Het koppelstuk bestaat doorgaans uit een tweetal in elkaar passende bandvormig-gesloten 15 kluisters Kv resp. Kr, met een bandbreedte z en materiaaldikte s, opvolgend vierkantig dan wel rechthoekig op doorsnede; de maatvoeringen zijn: Kv = (x, x; z, s) resp. Kr = (x-2s, x; z, s), zoals aangegeven in de Figuren 1 t/m. 6. De buizenparen (Pi, P2) en (T3,T4) zijn bevestigd aan Kv; het paar (Ts, Tó) aan Kr: via een zestal bouten, door vlakgecentreerde gaten in de wanden van Kv en Kr geschroefd in de bodems van cylindertjes die zijdelings in de buiseinden zijn bevestigd. De polaire 20 bouten fungeren als draaiingsas voor de buizenkoppeling.The tubes fixed along the polar axis (rotation line) p (see Fig. 1 and Fig. 2) are P 1 and P 2; the pairs of opposed tubes that can be directed into the plumb plane are (T3, T4) resp. (Ts, Tö). The coupling piece generally consists of two mutually fitting band-shaped closed fuses Kv and resp. Kr, with a bandwidth z and material thickness s, successively square or rectangular in section; the dimensions are: Kv = (x, x; z, s) resp. Kr = (x-2s, x; z, s), as indicated in Figures 1 through. 6. The tube pairs (P1, P2) and (T3, T4) are attached to Kv; the pair (Ts, Tó) to Kr: through six bolts, screwed through flat centered holes in the walls of Kv and Kr into the bottoms of cylinders that are mounted laterally in the pipe ends. The polar bolts act as the axis of rotation for the tube coupling.

In de Figuren 3 en 4 zijn de ronde buizen vervangen door vierkantige en de eindstandige binnen-cylindertjes door dito U-vormige profielen, weer vastgezet in de buiswanden. De ronde buizen hebben buitendiameters van plm. Vi x; de vierkantige buizen van plm. 30 tot plm. 120 mm.In Figures 3 and 4, the round tubes are replaced by square ones and the terminal inner cylinders by ditto U-shaped profiles, again fixed in the tube walls. The round tubes have outside diameters of approx. Vi x; the square tubes of approx. 30 to approx. 120 mm.

Bij gebruik van wat dunnere, maar relatief dikwandige buizen - met doorsneden en wanddikten 25 van plm. 20 resp. 5 mm. - kunnen de bouten direct in de buiswand worden getapt, zoals aangegeven in de Figuren 5 t/m 13; de eindstandige hulpstukjes in de buizen zijn dan overbodig. De constructies in Fig.5 en Fig.6 bieden dezelfde oriëntatiemogelijkheden als die van Fig.1 en Fig.2. In Fig.7 is Kr vervangen door een tweetal bandvormige U-profielen, met wanddikte Vi s : U-2 = (x-2s, - ; z, Vi s) resp. U-3= (x-3s, - ; z, Yt s), die, gemonteerd, samen een afstand x overspannen, zoals eerder in Kr. 30 Het buizenpaar (Ts, T4) wordt collineair bevestigd aan Kv, evenals (Pi, P2); het paar (Ts, T«) is niet langer collineair, maar vrijelijk oriënteerbaar geworden.When using somewhat thinner, but relatively thick-walled tubes - with cross sections and wall thicknesses of approx. 20 resp. 5 mm. - the bolts can be tapped directly into the tube wall, as indicated in Figures 5 to 13; the terminal fittings in the tubes are then superfluous. The constructions in Fig. 5 and Fig. 6 offer the same orientation options as those of Fig. 1 and Fig. 2. In Fig. 7 Kr is replaced by two band-shaped U-profiles, with wall thickness Vi s: U-2 = (x-2 s, -; z, Vi s) resp. U-3 = (x-3s, -; z, Yt s), which, mounted together, span a distance x, as previously in Kr. The tube pair (Ts, T4) is collinearly attached to Kv, as well as (Pi, P2); the pair (Ts, T «) is no longer collinear, but has become freely orientable.

In de Figuren 8 t/m 10 zijn mogelijkheden, analoog aan die in de Figuren 5 t/m 7 weergegeven, maar het polaire buizenpaar (Pi, P2) is nu vervangen door één doorlopende buis Pv, die materieel als oriëntatie-as fungeert en op haar plaats wordt gehouden door een tweetal borgringen b om Pi,2 en tegen Kv aan.In Figs. 8 to 10, possibilities analogous to those in Figs. 5 to 7 are shown, but the polar tube pair (P 1, P 2) has now been replaced by one continuous tube Pv, which materially functions as an orientation axis and is held in place by two retaining rings b at Pi, 2 and against Kv.

5 In de Figuren 11 t/m 13 is (Pi, P2) eveneens vervangen door Pi,2, voorzien van borgringen b, terwijl Kv vervangen is door een paar U-profielen: Uo = (x, - ; z, Vt s) resp. U -1 = (x - s, z, lA s) die tesamen een afstand x overspannen in gemonteerde toestand, zoals eerder in Kv. Het buizenpaar (T5, Té) collineair, maar in Fig. 13 tenslotte ook vrij oriënteerbaar (evenals in Fig. 10), door de vervanging van Kr door het paar U-profielen U-2 en U-3.Deze constructie biedt dus de meeste 10 oriëntatie-vrij heden.In Figures 11 to 13, (P 1, P 2) has also been replaced by P 1, 2, provided with locking rings b, while K V has been replaced by a pair of U-profiles: U 0 = (x, -; z, Vt s) resp. U -1 = (x - s, z, 1A s) that together span a distance x in the mounted state, as previously in Kv. The tube pair (T5, Té) collinear, but in FIG. 13 finally also freely orientable (as in Fig. 10), by replacing Kr by the pair of U-profiles U-2 and U-3. This construction thus offers the most orientation freedom.

Claims (1)

Een goedkope en eenvoudig hanteerbare koppeling van zes (of minder) isometrische buizen is voorgesteld die een oriëntatie van vier hunner toelaat in een vlak, loodrecht op de oriëntatie-as, 5 waarlangs de overige twee buizen zijn bevestigd. Het koppelstuk maakt aanhechting dier zes buizen mogelijk, op gelijke afstanden hunner uiteinden tot deszelfs middelpunt, waardoor de buislengten eenvoudiger kunnen worden bepaald. Om vergaande oriënteerbaarheid binnen de buizenconstructie mogelijk te maken, is het koppelstuk samengesteld uit 2,1 óf 0 starre en oriënteerbare kluisters met resp. 0,1 of 2 oriënteerbare paren van 10 dito U-profielen, waarop of waardoorheen de buizen worden bevestigd. 1038018An inexpensive and easily manageable coupling of six (or fewer) isometric tubes has been proposed that allows an orientation of four of them in a plane perpendicular to the orientation axis along which the remaining two tubes are attached. The coupling piece allows attachment of six tubes, at equal distances from their ends to its center, so that the tube lengths can be determined more easily. To enable far-reaching orientability within the tube construction, the coupling piece is composed of 2.1 or 0 rigid and orientable fleets with resp. 0.1 or 2 orientable pairs of 10 ditto U-profiles, on which or through which the tubes are attached. 1038018
