Description
7811105-6 in pluggen med den ett stycke idragna fästskruven p g a den utmed he- la pluggen förhöjda friktionen, som ju förstärks ytterligare genom flänsarna. Vid för stora hål finns å andra sidan risken att pluggen snurrar när fästskruven dras i, eftersom ett förhindrande av snurr- ningen är avhängigt av att flänsarna verkligen pressar mot borrhålets gväggar. Monteringen och förankringen av den kända pluggen är alltså förenade med mycket knappa borrhâlstoleranser. 7811105-6 insert the plug with the one-piece fastening screw tightened due to the friction increased along the entire plug, which is of course further strengthened through the flanges. In the case of oversized holes, on the other hand, there is a risk that the plug will spin when the fixing screw is tightened, as prevention of the rotation is dependent on the flanges actually pressing against the borehole walls. The assembly and anchoring of the known plug are thus associated with very tight borehole tolerances.
Uppfinningen har till uppgift att vidga toleransområdet för de borrhâl som kan användas för en riktig montering och förankring.The object of the invention is to widen the tolerance range for the boreholes which can be used for a correct assembly and anchoring.
Enligt uppfinningen uppnås detta genom att pluggen har en e- lipsformad ytterprofil, varvid den större elipsdiametern är något större och den mindre elipsdiametern lika med eller något mindre än den del av fäetskruven som när in i pluggen, samt att slitsarna och flänsarna är anordnade utmed den del av pluggen där elipsdiametern är mindre.According to the invention this is achieved in that the plug has an elliptical outer profile, the larger ellipse diameter being slightly larger and the smaller ellipse diameter equal to or slightly smaller than the part of the mounting screw which reaches into the plug, and that the slots and flanges are arranged along the part of the plug where the ellipse diameter is smaller.
Utformningen enligt uppfinningen medför en utplaning av pluggen vid flänsarna, medförande att friktionen vid pluggens införande mins- kar. Dessutom innebär den elipsformade ytterprofilen minskad gods- tjocklek i detta område, vilket medför förbättrad elasticitet, som i sin tur underlättar pluggens utvidgning inåt. Tack vare denna elasti- citet, som förhöjs ytterligare genom slitsarna, låter sig pluggen lät- tare pressas samman för att passa in i ett mindre borrhål. Den varie- rande godstjockleken hos pluggen medför emellertid ej någon försäm- ring av förankringen, då allt pluggmaterial p g a diameterförhållande- na blir jämnt fördelat och fastkilat i borrhålet genom fästskruvens gängor.The design according to the invention entails a flattening of the plug at the flanges, which means that the friction during the insertion of the plug decreases. In addition, the elliptical outer profile means reduced material thickness in this area, which results in improved elasticity, which in turn facilitates the inward expansion of the plug. Thanks to this elasticity, which is further increased by the slots, the plug can be more easily compressed to fit into a smaller borehole. However, the varying wall thickness of the plug does not cause any deterioration of the anchorage, as all plug material is evenly distributed and wedged in the borehole through the threads of the fastening screw due to the diameter conditions.
Vid större borrhål medför pluggens elipsform friktionskontakt ej endast för flänsarna utan även för pluggens tjockare del. Genom den ökade friktionen minskar risken för att pluggen skall snurra i större borrhål. Utformningen enligt uppfinningen vidgar därmed det toleransområde inom vilket montering och stabil förankring är möjli- ga.For larger boreholes, the elliptical shape of the plug causes frictional contact not only for the flanges but also for the thicker part of the plug. The increased friction reduces the risk of the plug spinning in larger boreholes. The design according to the invention thus widens the tolerance range within which mounting and stable anchoring are possible.
I en annan utformning av uppfinningen kan förhållandet mellan den större och den mindre elipsdiametern uppgå till 1 I 0,94 till 0,96. ikitningen visar ett utförandeexempel av uppfinningen, varvid fig 1 visar ett delsnitt av uppfinningens plugg med idragen fästskruv, fig 2 pluggen enligt fig 1 sedd framifrån.In another embodiment of the invention, the ratio between the larger and the smaller ellipse diameter may amount to 1 L 0.94 to 0.96. The drawing shows an exemplary embodiment of the invention, wherein Fig. 1 shows a partial section of the plug of the invention with the fixing screw tightened, Fig. 2 the plug according to Fig. 1 seen from the front.
För att pluggen 1 skall kunna förankras krävs att såväl väggenIn order for the plug 1 to be able to be anchored, it is required that both the wall
