Firmaet Chas. Hude. ___ ‘ '· " :''· ~ (54) Selvskærende fastgørelsesorgan.The company Chas. Hude. ___ '' · ":" '· ~ (54) Self-tapping fastener.
Opfindelsen angår et selvskærende fastgørelsesorgan til anbringelse i ikke-metalliske materialer, såsom træ, gummi eller plast, og bestående af et rørformet organ, som i den ene ende har et skær, i den anden ende et drivorgan til drejning af fastgørelsesorganet og på ydersiden et gevind.The invention relates to a self-tapping fastener for placement in non-metallic materials, such as wood, rubber or plastic, and consisting of a tubular member having a cutter at one end, a drive means for turning the fastener and on the outside a thread.
Fra det danske patentskrift nr. 89.551 kendes en selvskærende skrue, som i den ydre ende har en udboring, som er forbundet med ydersiden af den gevindskårne del ved hjælp af langsgående,.^lid^er., affedes at skruen kommer til at virke i hovedsagen^ som en snittap,, og det materiale, som optages i hulrummet und·?: ihdskruningeri, vil „kunne undslippe gennem slidserne. ·,·>,,From Danish Patent Specification No. 89,551, a self-tapping screw is known which has a bore at the outer end which is connected to the outside of the threaded part by means of longitudinally extending members, so that the screw will work in the main thing ^ as a cut, ,, and the material which is absorbed into the cavity und? ihd curvature will 'be able to escape through the slits. ·, ·> ,,
Fra det tyske patentskrift nr., 424.322 kendes;-an træskxue, der har,'.It is known from German Patent No. 424,322;
2 141180 en gennemgående udboring, der strækker sig fra et fladt hoved med en tværgående kærv til et skær, som består af en forsat del, der er udformet som et knivblad.2 141180 is a continuous bore extending from a flat head with a transverse notch to a cutter, which consists of an offset portion formed as a knife blade.
Fastgørelsesorganet ifølge nærværende opfindelse er ejendommeligt ved, at skæret er en cirkulær kant, der er dannet ved skæring imellem det rørformede organs ydre og indre flader, hvoraf mindst den ene er konisk, og at den indre flade strækker sig ubrudt fra skæret til en lukket ende i nærheden af drivorganet.The fastener according to the present invention is characterized in that the cutter is a circular edge formed by cutting between the outer and inner surfaces of the tubular member, at least one of which is conical and that the inner surface extends continuously from the cutter to a closed end. near the drive means.
Ved et således udformet fastgørelsesorgan vil det cirkulære skær straks efter, at det er ført ind i materialet, aflukke den i fastgørelsesorganets hulrum indførte materialeprop, og der vil derfor dannes en fuldstændig intakt materialeprop af samme form som hulrummet og fuldstændig udfyldende dette, hvorved der opstår et indre lufttryk ved hulrummets lukkede ende, hvorved materialeproppen sammentrykkes og trykkes ud imod hulrummets vægge, således at der i forhold til den kendte teknik tilvejebringes en bedre fastholdelse af fastgørelsesorganet i materialet.With such a fastener, the circular cutter immediately after it is inserted into the material closes the material plug inserted into the cavity of the fastener, and therefore a completely intact material plug of the same shape as the cavity will form and completely fill it, thereby forming an internal air pressure at the closed end of the cavity, whereby the material plug is compressed and pressed out against the walls of the cavity, so that, relative to the prior art, a better retention of the fastening means in the material is provided.
Ved udførelsesformen ifølge krav 2 vil det indre hulrum, som optager materialeproppen, være cylindrisk, således at også materialeproppen bliver cylindrisk og derfor kan ligge an imod hele hulrummets indre flade. Da gevindet udgår fra den indre ende af den koniske del, vil det hurtigt kunne bringes i indgreb med arbejdsstykkets materiale, således at et særligt stort tryk eller endog slag på fastgørelsesorganet ved begyndelsen af indføringsoperationen overflødiggøres.In the embodiment according to claim 2, the inner cavity receiving the material plug will be cylindrical so that the material plug also becomes cylindrical and can therefore abut against the entire interior surface of the cavity. Since the thread is projected from the inner end of the tapered part, it can be quickly engaged with the workpiece material, so that a particularly large pressure or even impact on the fastener at the beginning of the insertion operation is unnecessary.

Slidte og beskadigede dele af foringen kan erstattes ved at skære sådanne dele bort og an- * O'1" .. i" .· bringe nyt foringsmateriale på deres plads, hvilket derefter fastgøres permanent ved hjælp af.fastgørelsesorganet. ;Once the fastener is inserted, the liner is permanently retained. in place by means of a nut 25. Worn and damaged parts of the liner can be replaced by cutting such parts away and applying * * 1 ".. in". · replacing new liner material which is then permanently attached by with the aid of the fastener. ;
Fig. 14 viser, hvorledes to ikke-metalliske materialestykker fastgøres til hinanden uden anvendelse af forhorede huller.FIG. 14 shows how two non-metallic pieces of material are attached to each other without the use of interrogated holes.
De to materialestykker 30 og 31 anbringes først i ønsket stilling.The two pieces of material 30 and 31 are first placed in the desired position.
Det selvskærende fastgørelsesorgan ifølge fig. 5-8 indskrues gennem det første materialestykke 30 i det erødet materialestykke 31.The self-tapping fastener of FIG. 5-8 are screwed through the first piece of material 30 into the eroded piece of material 31.
De to kerner 30a, 31a trykkes sammen i fastgøreisesorganet gennem den indelukkede lufts trykvirkning og volumenformindskelsen, hvilket i høj grad forøger modstandskraften imod udtrækning- og skruekræfter.The two cores 30a, 31a are compressed in the securing means through the compressed air's compressive action and the volume decrease, which greatly increases the resistance to extraction and screw forces.
Ved anvendelse af fastgørelsesorganet ifølge opfindelsen anbringes det over arbejdsstykket, d.v.s. gummi eller træ, og indskrues således, at skæreæggen 15 skærer arbejdsstykkets materiale 17 i ar-kuell retning. Ved fortsat indskruning vil det skarpe gevinds indgang gøre indgreb i materialet 17. Ved fortsat indskruning skærer den skarpe æg sig ind i arbejdsstykket i en skruelinieformet bane.When using the fastener according to the invention, it is placed over the workpiece, i.e. rubber or wood, and screwed in such that the cutting edge 15 cuts the workpiece material 17 in an arcuate direction. When continued screwing in, the sharp thread input will engage the material 17. When continued screwing, the sharp egg cuts into the workpiece in a helical web.
Når fastgørelsesorganet drejes, vil det skarpe gevind skære og arbejde sig ind i gummiet (eller mellem fibrene) samt tilvejebringe tæt anlæg imellem arbejdsstykket og det skarpe gevind.When the fastener is rotated, the sharp thread will cut and work into the rubber (or between the fibers) and provide tight contact between the workpiece and the sharp thread.
Det beskrevne fastgørelsesorgan tilvejebringer således en meget ubetydelig forspænding af arbejdsstykkets materiale 17, især når dette består af træ, hvor dir ikke opstår nogen brud på træfibrene.Thus, the fastener described provides a very negligible biasing of the workpiece material 17, especially when it consists of wood where no breakage of the wood fibers occurs.
