(54) Koblings anordning til udløselig sammenkobling af to elementer, fortrinsvis bygningsstilladsele= menter.(54) Coupling device for releasable coupling of two elements, preferably building scaffolding elements.
Opfindelsen angår en koblingsanordning til udløselig sammenkobling af to elementer, fortrinsvis bygningsstilladselementer og lignende dele.The invention relates to a coupling device for releasably coupling two elements, preferably building scaffolding elements and similar parts.
Formålet med opfindelsen er først og fremmest at tilvejebringe en enkel og effektiv koblingsanordning, som kan eliminere behovet for forskellige typer klammer, skruetvinger, bolteforbindelser og lignende OQ forbindelser, som hidtil er anvendt til sammenkobling af forskellige Γ**· bygningsstilladselementer, og som medfører, dels at rejsningen af stillad- (*5 serne bliver tidskrævende og kræver stor erfaring hos personalet, dels at demonteringen bliver besværlig ved, at de mange skrue-møtriks-r— forbindelser ofte ruster og bliver vanskelige af løsne.The object of the invention is first and foremost to provide a simple and effective coupling device which can eliminate the need for different types of clamps, screws, bolt connections and similar OQ connections used so far to interconnect different building scaffolding elements and which entail, partly that the erection of the scaffolding (* 5) becomes time-consuming and requires considerable experience with the staff, and that the disassembly becomes difficult because the many screw-nut r connections often rust and become difficult to loosen.

Koblingsanordningen ifølge opfindelsen, som er særligt egnet til at anvendes til sammenkobling af to bygningsstilladselementer, men som også kan anvendes i andre forbindelser, er ejendommelig ved en med det ene element fast forbundet første koblingsdel med mindst to i afstand fra hinanden parallelt udragende tappe, som hver på sin fri ydre ende har et flangeparti, og en med det andet element fast forbundet anden kbblingsdel med mindst to med hver sin tap samvirkende koblingsorganer, som hver har en åbning med U-form i et plan vinkelret på tappenes længdeakser, hvilken åbning har en bredere til tappens . flangeparti tilpasset indre del og en smallere, til selve tappen tilpasset ydre del, hvorhos hovedaksen for den U-formede åbning i et koblingsorgan forløber vinkelret på hovedaksen for den U-formede åbning i det andet koblingsorgan henholdsvis de andre koblingsorganer, hvilke hovedakser på sin side i' det mindste i hovedsagen tangerer en cirkel, hvis midterpunkt ligger i centrum af tappen i den U-formede åbning i det førstnævnte koblingsorgan.The coupling device according to the invention, which is particularly suitable for use in interconnecting two building scaffolding elements, but which can also be used in other connections, is characterized by a first coupling part fixed to the one element with at least two spaced apart parallel pins which each at its free outer end has a flange portion, and a second coupling member connected to the other element by at least two coupling members cooperating with each other, each having a U-shaped opening in a plane perpendicular to the longitudinal axes of the pins, which opening has one wider to the pin. flange portion adapted to the inner portion and a narrower portion adapted to the pin itself, wherein the main axis of the U-shaped opening in a coupling member extends perpendicular to the main axis of the U-shaped opening in the second coupling means or the other coupling means, respectively, which main axis at least substantially a circle whose center point is at the center of the pin of the U-shaped opening in the first-mentioned coupling means.
En koblingsanordning af denne art er fordelagtig ved at være af en enkel og robust konstruktion. Anordningen har ingen gevind, som kan ruste sammen, og der findes heller ingen løse dele, som kan blive borte. Sammenkoblingen af de to koblingsdele er meget enkel og kan kun udføres på én måde, hvorfor der ikke kræves nogen erfaring. Sammenkoblingen sker ved, at den anden koblingsdels første koblingsorgans U-formede åbning først føres over den tilhørende tap på den første koblingsdel. Derefter svinges den anden koblingsdel omkring tappen, så at dens andet koblingsorgan føres mod den anden tap (når der kun findes ét andet koblingsorgan). Ved at det andet koblingsorgans U-formede åbning strækker sig tangentielt på den foran angivne måde, kan den anden tap føres ind i åbningen. Eftersom de to U-formede åbninger ikke er parallelle, er det første koblingsorgan automatisk låst til sin tap, så længe det andet koblingsorgan holdes på sin tilhørende tap. Dette kan ske på forskellige måder. Hvis tappene f.eks. er anbragt på en vertikal stang til et bygningsstillads, og koblingsorganerne er anbragt på en tværbom mellem to stænger, så kan en længdebom mellem to tværbomme fiksere det andet koblingsorgan på sin tap.A coupling device of this kind is advantageous in being of a simple and robust construction. The device has no threads that can rust together, nor are there any loose parts that can get lost. The coupling of the two coupling parts is very simple and can only be performed in one way, so no experience is required. The coupling is effected by first passing the U-shaped opening of the second coupling part over the corresponding pin on the first coupling part. Then, the second coupling member is pivoted around the pin so that its second coupling member is guided toward the second pin (when only one other coupling member exists). By extending the U-shaped opening of the second coupling member tangentially in the manner stated above, the second pin can be inserted into the opening. Since the two U-shaped openings are not parallel, the first coupling means is automatically locked to its pin as long as the second coupling means is held on its associated pin. This can happen in different ways. For example, if the pins. is placed on a vertical bar for a building scaffold, and the coupling means are arranged on a cross bar between two bars, then a long bar between two cross bar can fix the other coupling member on its pin.
Ved .en speciel udformning af koblingsanordningen er det særligt fordelagtigt som låseorgan for det andet koblingsorgan at udnytte en fald-bøjle af den type, som anvendes i det bygningsstillads, som er beskrevet i svensk fremlæggelsesskrift nr. 350.796. Denne faldbøjle anvendes til at låse krydsstag, gelændere eller rækværker og lignende dele, og den kan på simpel måde forlænges, så der dannes et par anslagsflader 3 144317 på hver side af det andet koblingsorgan. Ved på denne måde at give den kendte faldbøjle en yderligere funktion fås en meget enkel og sikker koblingsanordning.In a special design of the coupling device, it is particularly advantageous as a locking means for the second coupling means to utilize a drop-bar of the type used in the building scaffold described in Swedish Patent Specification No. 350,796. This drop bar is used to lock crossbars, handrails or handrails and similar parts, and it can be extended in a simple manner to form a pair of impact faces 3 144317 on each side of the other coupling member. By providing a further function to the known drop bar in this way, a very simple and secure coupling device is obtained.
Opfindelsen beskrives nærmere i det følgende i forbindelse med tegningen, der viser en udførelsesform for koblingsanordningen ifølge opfindelsen, og hvor fig. 1 set fra siden viser en del af et par bygningsstilladselementer med en udførelsesform for koblingsanordningen ifølge opfindelsen, fig. 2 et snit efter linien II-II i fig. 1, fig. 3 et snit efter linien XII-III i fig. 1 og fig. 4 set fra siden en del af en længdebom, der er tilsluttet en tværbom.The invention will be described in more detail in the following with reference to the drawing, which shows an embodiment of the coupling device according to the invention, and in which fig. Figure 1 is a side view of a portion of a pair of building scaffolding elements with an embodiment of the coupling device according to the invention; 2 is a sectional view taken along line II-II of FIG. 1, FIG. 3 is a sectional view taken along line XII-III of FIG. 1 and FIG. 4 is a side view of part of a longitudinal boom connected to a transverse boom.
I fig. 1 er vist en del af en vertikal stang 1 til et bygningsstillads, som ved hjælp af en koblingsanordning ifølge opfindelsen er forbundet med den ene ende af en tværbom 2, hvis modsatte, ikke viste ende forudsættes forbundet med en anden vertikal stang ved hjælp af en tilsvarende koblingsanordning ifølge opfindelsen.In FIG. 1, a part of a vertical bar 1 is shown for a building scaffold which is connected by means of a coupling device according to the invention to one end of a transverse boom 2, whose opposite, not shown end is connected to another vertical rod by means of a corresponding coupling device according to the invention.
Tværbommen 2 består af to parallelle rør 3, som er forbundet med hinanden ved hjælp af påsvejsede stålplader 4. Ved enderne af rørene 3 findes klolignende, rørformede elementer 5 og 6, der er fast-svejst og danner koblingsanordningens ene koblingsdel. Elementernes 5 og 6 klolignende form er tilvejebragt ved hjælp af U-formede åbninger henholdsvis 7 og 8, som har en bredere indre bunddel henholdsvis 9 og 10 og en smallere ydre del henholdsvis 11 og 12. Som det tydeligt ses af fig. 3, danner åbningerne 7 og 8 en vinkel på 90° med hinanden.The cross bar 2 consists of two parallel tubes 3 which are connected to each other by means of welded steel plates 4. At the ends of the tubes 3 are claw-like tubular elements 5 and 6 which are welded together and form one coupling part of the coupling device. The claw-like shape of the elements 5 and 6 is provided by U-shaped openings 7 and 8, respectively, which have a wider inner bottom part 9 and 10 and a narrower outer part 11 and 12, respectively. 3, the openings 7 and 8 form an angle of 90 ° with each other.
De klolignende elementer 5 og 6 griber ind over et par tappe 13, som danner koblingsanordningens anden koblingsdel og er fast forbundet med stangen l,f.eks. ved svejsning. Tappene 13 har en flange 14 ved deres yderende, hvis diameter er tilpasset til åbningernes 7 og 8 bredere bunddele 9 og 10, medens diameteren på selve tappen 13 er tilpasset til de samllere ydre dele 11 og 12.The claw-like elements 5 and 6 engage over a pair of pins 13 which form the second coupling member of the coupling device and are firmly connected to the rod 1, e.g. by welding. The pins 13 have a flange 14 at their outer end, the diameter of which is adapted to the wider bottom portions 9 and 10 of the openings 7 and 8, while the diameter of the pin 13 itself is adapted to the outer collectors 11 and 12.

Ved det beskrevne arrangemait kan stangen 1 og tværboromen 2 kobles sammen ved, at elementet 5 med bommen hældende føres skråt oppefra og ned mod den øvre tap, som føres ind i åbningen 7. Herefter kan bommen 2 svinges omkring den øvre tap 13, så at det nedre klolignende element 6 føres mod den nedre tap. Eftersom hovedaksen for den nedre U-formede åbning 8 strækker sig tangentialt til en cirkel, hvis midtpunkt ligger på den øvre taps 13 centerakse, således som det tydeligt ses af fig. 3, så kan den nedre tap nu føres ind i åbningen 8. Det bemærkes imidlertid, at åbningen 8 er relativt lidet dyb i forhold til bredden, og at dette tillader ' åbningen at strække sig direkte tangentialt. Hvis man af forskellige grunde skulle ønske en dybere åbning i det nederste element 6, så må åbningens sidekanter naturligvis gives en vis krumning langs med den ovennævnte ' cirkels cirkelbue. Selv en på denne måde udformet åbning skal omfattes af udtrykket "i hovedsagen tangerer" i de efterfølgende patentkrav.At the arrangement described, the rod 1 and the transverse bore 2 can be connected together by the element 5 with the boom inclined inclined upwards and downwards towards the upper pin which is inserted into the opening 7. Thereafter, the boom 2 can be pivoted about the upper pin 13, so that the lower claw-like element 6 is guided toward the lower tab. Since the major axis of the lower U-shaped aperture 8 extends tangentially to a circle whose center is on the center axis of the upper pin 13, as is clearly seen in FIG. 3, the lower pin can now be inserted into the aperture 8. However, it is noted that the aperture 8 is relatively slightly deep in relation to the width, and this allows the aperture to extend directly tangentially. If, for various reasons, a deeper opening should be desired in the lower element 6, then the lateral edges of the opening must of course be given a certain curvature along the circular arc of the above-mentioned. Even an aperture formed in this way must be included in the term "substantially tangent" in the appended claims.
Som det især ses af fig. 3, er det øverste element 5 automatisk fikse-ret på den øvre tap 13, så snart den nedre tap 13 indføres i det nederste element 6. Fikseringen af det nederste element 6 på dets tap kan tilvejebringes på forskellige måder som illustreret i fig. 1 og 4.As seen especially in FIG. 3, the upper element 5 is automatically fixed to the upper pin 13 as soon as the lower pin 13 is inserted into the lower element 6. The fixation of the lower element 6 on its pin can be provided in various ways as illustrated in FIG. 1 and 4.
I fig. 1 er vist anvendelsen af en såkaldt faldbøjle 20, som samtidigt kan anvendes til at låse gelændere, krydsstag og lignende elementer, således scm antydet med streg-prik-linier. Faldbøjlen 20 består af en dobbelt U-bukket plade med en del 21, som griber om stangen 1, og en låsedel 22 med en slids for en tap 24, som holder de foran nævnte dele. Faldbøjlen 20 er vertikalt forskydelig på stangen og holdes i den i fig. 1 viste låsestilling ved sin egen tyngde. På faldbøjlens U-formede del 21 er udformet et par anslag 23. Disse kan enten være udført ud i ét stykke med delen 21 eller være særskilte plader, som fastsvejses til delen 21. I den i fig. 1 viste stilling ligger anslagene 23 på hver side af det nederste element 6, som derved er fikseret på tappen 13. Fordelene ved koblingsanordningen ifølge opfindelsen er således særligt fremtrædende, når en allerede eksisterende faldbøjle kan udnyttes som låseorgan.In FIG. 1, there is shown the use of a so-called drop bar 20, which can simultaneously be used to lock handrails, cross stays and similar elements, thus indicated by dash-dotted lines. The drop bar 20 consists of a double U-bent plate with a portion 21 gripping the rod 1 and a locking portion 22 with a slot for a pin 24 holding the aforementioned parts. The drop bar 20 is vertically displaceable on the rod and is held in the position shown in FIG. 1 shown at its own weight. A pair of abutments 23 are formed on the U-shaped part 21 of the drop bar 23. These can either be made integrally with the part 21 or be separate plates which are welded to the part 21. In the embodiment shown in FIG. 1, the abutments 23 lie on each side of the lower member 6, which is thereby fixed on the pin 13. Thus, the advantages of the coupling device according to the invention are particularly prominent when an already existing drop bar can be utilized as a locking means.
I fig. 4 er vist endnu en mulighed for at hindre tværbommen 2 i at svinges, så det nederste element 6 kan føres væk fra tappen 13. Tværbommen 2 er her forsynet med en konsol 30, som bærer en vertikal tap 31. Konsollen 30 med tappen 31 danner holder for en længdebom 32, som f.eks. forbinder to tværbomme med hinanden. Længdebommen 32, hvis venstre ende er vist i fig. 4, har et øre 33, gennem hvilket tappen 31In FIG. 4, there is shown another possibility of preventing the transverse boom 2 from pivoting, so that the lower element 6 can be moved away from the pin 13. The transverse boom 2 is here provided with a bracket 30 which carries a vertical pin 31. The bracket 30 with the pin 31 forms holding for a longitudinal boom 32, e.g. connecting two cross-bars with each other. The longitudinal boom 32, the left end of which is shown in FIG. 4, has an ear 33 through which the pin 31
