Description

8207021-0 lﬂ l5 20 25 30 l fig. betecknar siffran i generellt ett av de element, t.ex. en verti- kalt anordnad stolpe, som skall förbindas med ett huvudsakligen hori- sontellt förlöpande element. generellt betecknat 2. Elementen l och 2 består vanligtvis av rör för byggnadsställningar och liknande. 8207021-0 l ﬂ l5 20 25 30 l Fig. Denotes the number in generally one of the elements, e.g. a vertically arranged post, which is to be connected to a substantially horizontally extending element. generally denoted 2. Elements 1 and 2 usually consist of scaffolding pipes and the like.

Som framgår av ritningen uppvisar de vertikala elementen 1 en eller fiera bygel; eller hylsformade delar 3, anordnade i anslutning till de önskade förbindningsställena. Dessa delar, i fortsättningen be- nämnda byglar, är vanligtvis fastsvetsade vid de vertikala elementen och tjänar till att samverka med den med siffran Ä generellt beteck- nade nya kopplingsanordnlngen.As can be seen from the drawing, the vertical elements 1 have one or more stirrups; or sleeve-shaped parts 3, arranged in connection with the desired connection points. These parts, hereinafter referred to as stirrups, are usually welded to the vertical elements and serve to cooperate with the new coupling device generally referred to by the number Ä.

Denna kopplingsanordning innefattar ett ihakningselement 5, vilket enligt fig. 4 uppvisar en övre vägg 6, från vilkens ena ände i rät vinkel nedåt utgår en ingreppsdel 7 och från vilkens motsatta ände utgår en nedåtriktad vägg 8, vilken bildar spetsig vinkel med den övre väggen och i sin tur övergår i en med den övre väggen 6 parallell nedre vägg 9. l den övre väggen är anordnad en genomgående, långsträckt öppning 10, vilken vid li är vidgad för ett syfte som senare skall anges.This coupling device comprises a hooking element 5, which according to Fig. 4 has an upper wall 6, from one end of which at a right angle downwards an engaging part 7 emanates and from the opposite end of which a downwardly directed wall 8 emerges, which forms an acute angle with the upper wall and in turn merges into a lower wall 9 parallel to the upper wall 6. In the upper wall a continuous, elongate opening 10 is arranged, which at li is widened for a purpose to be stated later.

I den nedre väggen 9 är anordnad en med öppningen 10 parallellt för- löpande slits 12, vilken utgår från den nedre väggens 9 fria ände.Arranged in the lower wall 9 is a slot 12 extending parallel to the opening 10, which emanates from the free end of the lower wall 9.

Som framgår av fig. l-3 är ihaknlngselementet 5 fäst vid ena änden av det horisontella elementet l, företrädesvis genom svetsning.As can be seen from Figs. 1-3, the hanging element 5 is attached to one end of the horizontal element 1, preferably by welding.

Kopplingsanordningens andra del, vilken har den generella beteckningen l3, utgöres av en särskilt formad kil, vilken uppvisar en övre sidoyta ika och en i linje med denna befintlig nedre sidoyta iüb. Mellan dessa ytor uppvisar kilen i sin i fig. vänstra sida en urtagning 15, vilken begränsas av en från den nedre ytan lßb utgående sned yta 16, vilken i sin tur övergår i en med ytorna lka, iüb parallell inre yta 17, vil- ken befinner sig på ett avstånd från ett plan genom ytorna lüa, lüb som huvudsakligen motsvarar avståndet mellan elementets i yttre yta och bygelns 3 yttre yta.The second part of the coupling device, which has the general designation 13, consists of a specially shaped wedge, which has an upper side surface ika and a lower side surface iüb in line therewith. Between these surfaces the wedge has on its left side in the fig. A recess 15, which is delimited by an inclined surface 16 emanating from the lower surface lßb, which in turn merges into an inner surface 17 parallel to the surfaces, which is at a distance from a plane through the surfaces lüa, lüb which substantially corresponds to the distance between the outer surface of the element and the outer surface of the bracket 3.

ID 20 25 30 8207021-0 Kilens högra sida 18 utgör kilens verksamma snedyta och i sin övre ände är kilen formad som en hammarskaftsliknande anslagsdel 19.ID 20 25 30 8207021-0 The right side 18 of the wedge constitutes the effective inclined surface of the wedge and at its upper end the wedge is shaped as a hammer shaft-like abutment part 19.

Från kilen utgår i nntsatta riktningar två stift 20, Zl, vilka som framgår av fig. l-3är anordnade snett ovanför varandra och på ett av- stånd som överstiger tjockleken av ihakningselementets S övre vägg 6 för ett syfte som senare skall anges.From the wedge two pins 20, Z1 emanate in the inserted directions, which as shown in Figs. 1-3 are arranged obliquely above each other and at a distance which exceeds the thickness of the upper wall 6 of the hooking element S for a purpose to be stated later.

Den nu beskrivna anordningen fungerar på följande sätt: l utgångsläget befinner sig kilen i ett övre overksamt läge, i vilket den av sin egen tyngd intar det visade, något snedställda läget. Kilen har sin tyngdpunkt så belägen, att den i det visade övre läget kommer att med sin övre tapp 20 anligga mot översidan av väggen 6 och med sin undre tapp i anliggning mot väggens 6 undersida. Tappen 21 är nämligen belägen på den sida av kilen, som ej vetter mot sidourtaget ll i öpp- ningen 10 och i det visade läget befinner sig tappen 20 på sidan om nämnda sidourtag.The device now described works as follows: In the initial position the wedge is in an upper inactive position, in which it, by its own weight, assumes the position shown, somewhat obliquely. The wedge has its center of gravity so that in the upper position shown it will abut with its upper pin 20 against the upper side of the wall 6 and with its lower pin abutting against the underside of the wall 6. Namely, the pin 21 is located on the side of the wedge which does not face the side recess 11 in the opening 10 and in the position shown the pin 20 is located on the side of said side recess.

Med kilen i detta läge förs det horisontella elementet 2 till det i fig. l visade inriktningsläge, där ihakningselementets sidoöppning befinner sig i inriktning med bygeln 3 hos det vertikala elementet, varefter det horisontella elementet förskjuts åt vänster så att ihak- ningselementets vägg 7 och/eller väggens 9 ändparti kommer till anslag mot det vertikala elementet I. I detta läge sker ihakning genom att det horisontella elementet sänks, varvid ingreppsdelen 7 ingår i mellan- rummet mellan bygeln 3 och det vertikala elementet (se fig. 2).With the wedge in this position, the horizontal element 2 is moved to the alignment position shown in Fig. 1, where the side opening of the hooking element is in alignment with the bracket 3 of the vertical element, after which the horizontal element is displaced to the left so that the hooking element wall 7 and / or the end portion of the wall 9 abuts against the vertical element I. In this position hooking takes place by lowering the horizontal element, the engaging part 7 being included in the space between the bracket 3 and the vertical element (see Fig. 2).

För att fixera läsningen behöver man endast skjuta eller vippa kilen 13 något i pilriktningen i fig. 2 för att dess övre tapp 20 skall kunna passera igenom sidourtagningen ll i ihakningselementet. Av sin egen tyngd glider nu kilen ned till det i fig. 3 visade läget och gen- om att med en hammare e.d. slå mot anslagsytan 19 ernår man en kraftig förankring av delarna.To fix the reading, it is only necessary to push or tilt the wedge 13 slightly in the direction of the arrow in Fig. 2 in order for its upper pin 20 to be able to pass through the side recess 11 in the hooking element. By its own weight, the wedge now slides down to the position shown in Fig. 3 and through that with a hammer e.d. hitting the abutment surface 19, a strong anchoring of the parts is achieved.

Genom att kilen 13 dels är styrd i urtagningen 10 resp. slitsen 12, 8207021-0 vilka båda givetvis skall ha ungefärligen samma bredd som kilens tjock- lek, och dels anligger mot det vertikala elementet l såväl ovanför bygeln 3 (med ytan låa) som under densamma (med ytan lüb) och mot ihak- ningselementets vägg 8 (med ytan 18), ernås en synnerligen stabil och och vridfast förbindning.Because the wedge 13 is partly controlled in the recess 10 resp. the slot 12, 8207021-0 which both must of course have approximately the same width as the thickness of the wedge, and partly abut against the vertical element 1 both above the bracket 3 (with the surface low) and below it (with the surface lüb) and against the hook element wall 8 (with the surface 18), an extremely stable and torsionally resistant connection is obtained.

Det är givetvis lätt att lossa förbindningen genom att knacka kllen uppåt och vippa över den till det i flg. l visade utgångsläget och det är således så enkelt att verkställa såväl koppling som urkoppling, att detta kan utföras även av outbildad arbetskraft.It is of course easy to loosen the connection by tapping the clamp upwards and tilting over it to it as follows. 1 and it is thus so simple to carry out both coupling and disconnection that this can also be performed by untrained labor.
