Frembringelsen vedrører en indretning til sammenspænding af rør, der ved den ene ende er forsynet med en udadrettet vulst eller alternativt flere ud mod omkredsen placerede fremspring. Indretningen er af den 5 art, der er angivet i krav 1' s indledning. Sådanne rørstykker, i forbindelse med hvilke frembringelsen kan finde anvendelse, ses for eksempel i den danske mønsterregistrering MR 0508/1989.The production relates to a device for clamping pipes, which at one end are provided with an outwardly directed bead or alternatively several projections located against the circumference. The device is of the kind specified in the preamble of claim 1. Such pipe pieces, for which the production can be used, can be seen, for example, in the Danish pattern registration MR 0508/1989.
Frembringelsen vedrører nærmere bestemt en indretning med et spændebånd af den art, som fortrinsvis 5 anvendes til sammenspænding af rør af tynd plade, der for enderne har flanger eller udadrettede vulste, såsom spiralf alsede ventilationsrør og korntransportrør, eller til fastspænding af fx endedæksler på elektromotorer eller lignende. Kendte spændebånd af denne art er 10 almindeligvis udformet med en sammenspændingsindretning, der fx kan være et håndtag med en tråd- eller bladfjeder (en snaplås), hvor håndtaget og fjederen er direkte integreret i spændebåndet ved bertling eller lignende eller er fastgjort ved hjælp af beslag, der er monteret 15 på båndet ved nitning eller svejsning.More particularly, the invention relates to a device with a clamping band of the kind preferably used for clamping thin plate pipes having flanges or outwardly biased ends, such as spirally wound ventilation pipes and grain conveyor pipes, or for clamping, for example, end covers on electric motors or similar. Known fasteners of this kind are generally formed with a clamping device, which may be, for example, a handle with a wire or leaf spring (a snap lock), the handle and spring being directly integrated into the clamping belt by means of bracket or the like or fixed by means of brackets. which is mounted 15 on the belt by riveting or welding.
Der kendes også spændebånd, hvor spændebåndets ender er bukket vinkelret ud fra båndet og forsynet med gennemgående huller, og hvor båndet sammenspændes ved, at en skrue føres gennem de udadbukkede ender og en 20 fortrinsvis firkantet møtrik påsættes skruen, hvorefter skruen og møtrikken spændes sammen så spændebåndets ender føres mod hinanden.Also known are straps where the ends of the strap are bent perpendicularly from the strap and provided with through holes and where the strap is clamped by passing a screw through the outwardly bent ends and a preferably square nut is applied to the screw and then the screw and nut are tightened. the ends of the clamping band are pushed towards each other.
Disse kendte indretninger har imidlertid ganske komplicerede spændemekanismer. Sædvanligvis er de med 25 spændeskruen samvirkende modholdsorganer specielt udformet og placeret i individuelt konstruerede rum, som afgrænses af flere flanger på spændebåndet. Dette fordyrer konstruktionen.However, these known devices have quite complicated clamping mechanisms. Usually, the retaining means cooperating with the clamping screw are specially designed and placed in individually constructed spaces which are delimited by several flanges on the clamping band. This expensiveens the construction.
På baggrund heraf har er det hensigten med frem-30 bringeisen at tilvejebringe en enkel og billig spæn-deindretning, som ikke har de kendte spændebånds 2 2DK 94 00346 U3 ulemper. Dette opnås med en frembringelse af den indledningsvise art, der er ny ved, at spændebåndet har et i det væsentlige U-formet tværsnit med to flanger til sikkert greb omkring endevulsterne, at begge 5 spændebåndets ender danner en i de't væsentlige cylindrisk lomme, og at spændemekanismen omfatter to, i hver sin lomme placerede, cylindriske elementer, hvis største, udvendige tværmål er noget mindre end lommens mindste, indvendige tværmål, og som er frit drejelige 10 omkring deres akse inden i lommen, hvor det ene cylinderelement har et tværgående gevindhul, medens det andet cylinderelement har et tværgående frigangshul, og en spændeskrue strækker sig frit gennem frigangshullet, gennem frigangshuller i spændebåndets overfor hinanden 15 beliggende ender og endelig kommer i gevindindgreb med gevindhullet.In view of this, it is the object of the present invention to provide a simple and inexpensive clamping device which does not have the disadvantages of the known clamping straps 2DK 94 00346 U3. This is achieved by providing the initial kind new by the strap having a substantially U-shaped cross-section with two flanges for secure grip around the end bumps, that both ends of the strap form a substantially cylindrical pocket. and that the clamping mechanism comprises two cylindrical members, in each pocket, the largest outer cross-dimensions of which are somewhat smaller than the smallest inner cross-dimensions of the pocket, and which are freely pivotable about their axis within the pocket, the one cylinder element having a transverse threaded hole, while the second cylinder member has a transverse release hole and a clamping screw extends freely through the release hole, through release holes at the ends of the clamping belt 15 and finally engage the threaded hole.
Som følge af de cylindrisk udformede lommer ved spændebåndets ender og de indlagte qylindriske elementer opnås, at spændebåndet hovedsageligt udsættes for 20 tangentialkræfter under sammenspænldingen, fordi de to cylindriske elementer har mulighed for at dreje sig efterhånden som båndet spændes sammen til en mindre diameter. I kendte spændebånd af dån type, hvor fligene er bukket vinkelret ud fra båndene udsættes disse flige 25 derimod for kraftige momenter under sammenspændingen, idet de ikke er vinkelrette på sammenspændingsretningen. Spændebåndet ifølge frembringelsen har den yderligere fordel, at det er enkelt at fremstille, idet der ikke kræves nitning, lodning eller anden fastgørelse af 30 sammenspændingsdele, og at de anvendte cylindriske elementer og bolten kan være standårddele, der er frit tilgængelige på markedet. Lommerne kan f.eks. have et cirkulærcylindrisk tværsnit eller et kvadratisk tværsnit og de tilsvarende cylinderelementer kan have henholdsvis 35 et kvadratisk tværsnit og et cirkulærcylindrisk tværsnit.Due to the cylindrical pockets at the ends of the clamping belt and the inserted cylindrical elements, the clamping belt is mainly exposed to 20 tangential forces during the clamping, because the two cylindrical members have the ability to rotate as the belt is clamped to a smaller diameter. On the other hand, in known straps of that type, where the tabs are bent perpendicularly from the straps, these tabs 25 are subjected to strong moments during the clamping, since they are not perpendicular to the clamping direction. The clamping belt according to the invention has the additional advantage that it is simple to manufacture in that no riveting, soldering or other fastening of 30 clamping parts is required and that the cylindrical elements and the bolt used can be standard parts freely available on the market. The pockets can e.g. have a circular cylindrical cross section or a square cross section and the corresponding cylinder elements may have a square cross section and a circular cylindrical cross section, respectively.

Indretningen ifølge frembringelsen har den fremstillingstekniske fordel, at de to cylinderelementer let kan indføres fra siden i de tilhørende lommer i spænde-båndets ender. Spændebåndet leveres fortrinsvis med 5 cylinderelementerne allerede placeret i lommerne og spændeskruen ført gennem og i indgreb med hullerne i cylinderelementerne.The device according to the invention has the technical advantage that the two cylinder elements can be easily inserted from the side into the associated pockets at the ends of the strap. The clamping belt is preferably supplied with the 5 cylinder elements already placed in the pockets and the clamping screw passed through and in engagement with the holes in the cylinder elements.
I en foretrukken udførelsesform kan lommerne og cylinderelementerne have cirkulærcylindrisk tværsnit. 10 Herved opnås, at de cylindriske elementer får en større bæreflade i lommen, således at sammenspændingskraften fordeles over en større del af lommens overflade.In a preferred embodiment, the pockets and cylinder members may have circular cylindrical cross sections. Hereby, the cylindrical members are provided with a larger support surface in the pocket, so that the compressive force is distributed over a larger part of the pocket surface.
Frembringelsen vil nu blive nærmere forklaret ved hjælp af en udførelsesform og med henvisning til 15 tegningen, på hvilken fig. 1 er et delsnit af en rørsamling med et spændebånd ifølge frembringelsen set i retning I-I i fig. 3, fig. 2 et sidebillede af en ende af spændebåndet 20 i fig. 1, fig. 3 et delbillede af spændebåndets ender klar til sammenspænding, hvor rørene i rørsamlingen dog er udeladt af hensyn til overskueligheden.The invention will now be further explained by way of an embodiment and with reference to the drawing, in which fig. 1 is a partial section of a pipe assembly with a clamping belt according to the invention seen in direction I-I in fig. 3, FIG. 2 is a side view of one end of the clamping band 20 of FIG. 1, FIG. 3 is a partial view of the ends of the clamping strap ready for clamping, however, the pipes in the pipe joint are omitted for the sake of clarity.
fig. 3a og 3b delbilleder af to forskellige 25 udførelsesformer af lommer og cylinderelementer, og fig. 4 et sidebillede af spændebåndet med sammenspændingselementer .FIG. 3a and 3b show partial views of two different embodiments of pockets and cylinder elements; and FIGS. 4 is a side view of the clamping belt with clamping elements.
Spændebåndet 1 har som vist i fig. 1 et U-formet profil med to flanger la, lb, der her griber om to noget 30 skematisk viste rørstykker 10,20 med rundtgående endevulst 11, hhv. 21, der er dannet ved ombertling. Flangerne la, lb divergerer noget for at lette anbringelsen af spændebåndet 1 på vulsterne 11, 21.As shown in FIG. 1 shows a U-shaped profile with two flanges 1a, 1b, which here grips two somewhat schematically illustrated tubes 10,20 with circumferential end bead 11, respectively. 21, which is formed by ombertling. The flanges 1a, 1b diverge somewhat to facilitate the application of the clamping band 1 to the beads 11, 21.
Det i fig. 1-3 viste spændebånds cirkelbukkede 35 endeflige 2 danner lommer og er hver forsynet med et frigangshul 3, hvis akse i det væsentlige er parallel med tangenten til spændebåndet på det pågældende sted.The FIG. 1-3, the circularly bent 35 flaps 2 of the straps form pockets and are each provided with a clearance hole 3, the axis of which is substantially parallel to the tangent of the strap at that location.

Som det bedst ses af fig. 3 er der ved den ene endeflig indsat et møtrikelement 4 bestående af et kort cirkulærcylindrisk element med et tværgående gevindhul 4a. I den anden endeflig er indsat et andet element 5 5 ligeledes udformet som et kort cirkulærcylindrisk element, men med et tværgående frihul 5a for en spændeskrue 6.As best seen in FIG. 3, at one end tab is inserted a nut member 4 consisting of a short circular cylindrical element with a transverse threaded hole 4a. In the other end tab, a second element 5 5 is also formed as a short circular cylindrical element, but with a transverse clearance hole 5a for a clamping screw 6.
Som vist i fig. 3a og 3b kan der også placeres et cylinderelement med et kvadratisk tværsnit i en cirku-10 lærcylindrisk lomme, eller et cirkulærcylindrisk element i en lomme med et kvadratisk tværsnit. For at give plads for spændeskruen 6, er spændebåndéts endeflige ved de frie ender gaffelformede.As shown in FIG. 3a and 3b, a cylinder element having a square cross section in a circular cylindrical pocket or a circular cylindrical element in a pocket having a square cross section can also be placed. To make room for the clamping screw 6, the end flaps of the clamping straps at the free ends are fork-shaped.
