Fftrfarande och klammer fOr att till ett byggelement låsa ett flexibelt installationsrdrFeed procedure and staples to lock a flexible installation tube to a building element

Fdreliggande uppfinning avser ett fOrfarande och 5 en klammer fOr att till byggelement, fOretradesvis sådana uppbyggda på en stommme av regiar eller motsvarande och klådda med någon form av byggskiva eller panel, låsa genom hål i stomdelar och/eller ytbekiadnaden dragna fOr el-kabelfdrlåggning avsedda korrugerade flexibla installa-10 tionsrOr vid stommen eller ytbekiadnaden.The present invention relates to a method and a bracket for locking to building elements, preferably those built on a frame of regi or equivalent and clad with some form of building board or panel, through holes in the body parts and / or the surface coating drawn for electric cable coating. flexible installation tubes at the frame or surface coating.

Vid dragning av elektriska ledningar i hus omfat-tande byggelement uppbyggda på en stomme av regiar eller motsvarande och kiadda med någon form av byggskiva eller panel har det blivit allt vanligare att man fSrlagger led-15 ningarna i korrugerade flexibla installationsror istållet for styva ror, som kraver en omståndligare fdriaggnings-teknik med bl.a. anvåndandet av skarvmuffar och fdrbockade rdrkrttkar. De flexibla installationsrOren som levereras i stora långder i rullar kan fOrlåggas Over stora avstånd 20 och i svangar utan att behttva skarvas. Detta medfor emel-lertid den nackdelen att rdren lattare utsattes for påver-kan och hanger ner sig mellan två regiar och att, genom sådan påverkan uppkomna dragpåkanningar, kan overfdras Over långa strackor med påfdljd att rOren, om de inte ar ordent-25 ligt spikklamrade, kan glida ur sina infastningar i stutsar på exempelvis apparat- och koppiingsdosor. I många byggelement utgdres det enda klamringsunderlaget av gipsskivor, från vilka spikklammer latt lossnar.When wiring electrical wiring in houses comprising building elements built on a frame of regia or equivalent and coated with some form of building board or panel, it has become increasingly common to lay the wires in corrugated flexible installation pipes instead of rigid pipes, such as requires a more elaborate release technique including the use of joint joints and pre-curved tubes. The flexible installation pipes, which are delivered in large lengths in rollers, can be placed over large distances 20 and in pegs without having to be spliced. However, this causes the disadvantage that the tubes are more easily subjected to impact and hang down between two regions and that, due to such influence, tensile stresses can be transmitted over long stretches with pipes to the tube, if they are not properly nailed , can slip out of their attachments in bumps on, for example, appliance and junction boxes. In many building elements, the only clinging base is made of gypsum board, from which nail clips are easily detached.

Fdreliggande uppfinning har till andamål att anvisa 30 ett fdrfarande och en klammer fOr att till ett byggelement låsa ett flexibelt instal lat ionsriir på ett satt, som eli-minerar risken fOr att rOret skall glida om det utsattes fdr påverkan. Ett ytterligare andamål år att anvisa en klammer, som ar snabb att applicera och som inte kraver 35 anvdndandet av verktyg. Dessa åndamål uppnås genom ett 2 90481 forfarande och en klammer uppvisande de i efterfOljande patentkrav angivna kannetecknen.The present invention has for its object to provide a method and a clamp for locking a flexible element on a building element on a set which eliminates the risk of the pipe slipping if it is exposed to impact. A further object is to provide a staple which is quick to apply and which does not require the use of tools. These objects are achieved by a method and a staple having the jaw marks as set out in the following claims.

Uppfinningen skall beskrivas narmare i anslutning till bifogade ritning, i vilken 5 fig. 1 och 2, visar en klammer i perspektiv respek tive planvy, fig. 3 i perspektiv visar en klammer i lage fOr att appliceras på ett flexibelt installationsrOr anordnat i en våggregel, 10 fig. 4 i sektion visar en på ett installationsror applicerad klammer, fig. 5 visar samma klammer last vid installations-rOret genom dess inpassning i regeln och fig. 6 visar en klammer lasande åndpartiet av ett 15 installationsrOr till en pa vaggyta monterad koppiingsdosa.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to the accompanying drawing, in which Figures 1 and 2 show a staple in perspective and plan view respectively, Figure 3 in perspective shows a staple in layers for being applied to a flexible installation tube arranged in a wall rule, Fig. 4 is a sectional view of a clamp applied to an installation pipe, Fig. 5 shows the same clamp load at the installation pipe through its fitting into the rule, and Fig. 6 shows a clamp reading the spirit portion of an installation pipe to a cradle mounted junction box.

I figurerna 1 och 2, som visar klammern enligt uppfinningen i perspektiv respektive planvy betecknas klammem med 1. Klammern omfattar en genom ett centralt djupt urtag våsentligen U-formad skiva 2, varvid urtagets inre del 3 20 ar anpassad till diametern på ett installationsrors kor-rugeringsveck. Genom en fOrtrangning av urtaget vid ut-sprången 4, 5 år skivan 2 utformad att vid applicering på ett installationsrOr omsluta merparten av rOrets omkrets. Urtagets inre del 3 ar omgivet av en runt detsamma anordnad 25 i det visade utfOringsexemplet dubbelsidig krage 6, som i klammerns monterade tillstånd stracker sig utmed instal-lationsrOret och darvid låmnar det parti 7 av skivan 2, som år avsett att vara i ingrepp med installationsrOret fritt.In Figs. 1 and 2, which show the clamp according to the invention in perspective and plan view respectively, the clamp is denoted by 1. The clamp comprises a substantially U-shaped disc 2 through a central deep recess, the inner part 3 of the recess being adapted to the diameter of an installation tube. rugeringsveck. By displacing the recess at the projections 4, 5, the disc 2 is designed to enclose most of the tube's circumference when applied to an installation tube. The inner part 3 of the recess is surrounded by a two-sided collar 6 shown in the illustrated embodiment, which in the mounted condition of the bracket extends along the installation tube and thereby leaves part 7 of the disc 2 which is intended to be in engagement with the installation tube. free.

30 Figur 3 visar i perspektiv en klammer 1 i låge fOr att genom att fOras i pilens riktning appliceras på ett ur ett hål 8 i en likaledes i perspektiv visad och till en våggskiva 11 ansluten våggregel 9 framskjutande installationsror 10. 1 figur 4 visas delvis i genomskarning nåsta 35 fas av monteringen, i vilken klammern 1 år applicerad på 3 90481 installationsrCret 10 med partiet 7 i ingrepp med ett kor-rugeringsveck. Kragen 6 som stråcker sig utmed rOret 10 ar avsedd att vid rdrets 10 fdrskjutning i pilens riktning bringas till anligggning mot hålets 8 vågg på satt, som 5 visas i fig 5, varigenom fOrhindras att klammern 1 utvidgar sig och lossnar om rOret 10 utsattes for dragpåkanning från regelns 9 motsatta sida.Figure 3 shows in perspective a clamp 1 in position for being applied in the direction of the arrow to a installation tube 10 projecting from a hole 8 in a similarly shown perspective view and connected to a wall disc 11, Figure 1 is partly shown in FIG. intersecting the next phase of the assembly, in which the clip 1 is applied to 3 90481 installation circuit 10 with the portion 7 in engagement with a corrugation fold. The collar 6 extending along the tube 10 is intended to be brought into contact with the wall of the hole 8 in the direction of the arrow 8 in the direction of the arrow 10, as shown in Figure 5, thereby preventing the clamp 1 from expanding and loosening if the tube 10 is subjected to tensile stress. from the opposite side of the rule.

I figur 6 visas ett parti av en vaggskiva 12, i vilket andpartiet av ett installationsrOr 10 låsts med 10 en klammer 1. Over installationsrOret 10 har en med bot-tenhål forsedd partiellt visad kopplingsdosa 13 monterats. Dosan 13 ar fbrsedd med fdtter 14, av vilka en fot år visad, vilka fdtter lamnar utrymme fttr skivan 2 mellan dosans 13 botten och vaggskivan 12. Installationsrdret 15 10 ar har helt låst och kan varken dras ur eller skjutas in i dosan 13.In Figure 6, a portion of a cradle 12 is shown, in which the second portion of an installation tube 10 is locked with a clamp 1. Over the installation tube 10 a coupling box 13 partially shown with a bottom hole is mounted. The box 13 is provided with feet 14, of which one foot is shown, which feet leave space for the disc 2 between the bottom of the box 13 and the cradle 12. The installation pipe 15 is completely locked and cannot be pulled out or pushed into the box 13.

Genom installationsrdrens elasticitet år det mojligt att helt låsa ett r6r till en regel, varvid man efter att en klammer applicerats under elastisk deformation drar ut 20 rdret något på regelns motsatta sida och medan rdret ar spånt applicerar man en andra klammer på roret, som når det slåppes till en del, fjådrar tillbaka in i hålet och tar med sig den andra klammerns krage in i hålet, varvid aven denna klammer låses till rttret.Due to the elasticity of the installation spring, it is possible to completely lock a tube to a rule, where after a staple has been applied under elastic deformation, the tube is slightly extended on the opposite side of the rule and while the tube is chipped, a second clamp is applied to the tube, which reaches it. is partially dropped, springs back into the hole and takes the other clamp's collar into the hole, also locking this clamp to the tail.
