Description
Hylseformet utvidbar plugg. Sleeve-shaped expandable plug.
Oppfinnelsen angår en hylseformet utvidbar plugg med et konisk utsprengningslegeme som er forskyvbart i plugghylsen ved innskruning av en skrue i lengderetningen. The invention relates to a sleeve-shaped expandable plug with a conical expansion body which is displaceable in the plug sleeve by screwing in a screw in the longitudinal direction.
Ved de kjente utvidbare plugger er ut-spregningslegemet fremstilt av metall og utformet med metriske eller Withworth-gjenger. Utsprengningslegemer med gjenger for treskruer har hittil ikke vært kjent. In the case of the known expandable plugs, the protruding body is made of metal and designed with metric or Withworth threads. Explosive bodies with threads for wood screws have not been known until now.
For nu å skaffe en utvidbar plugg som kan anvendes for festeskruer av hvilken-somhelst type, blir det ifølge oppfinnelsen foreslått å fremstille pluggens utsprengningslegeme av et seigt, hårdt og eldebestandig kunststoff. I denne forbindelse er det vesentlig at utsprengningslegemets koniske ytterflate motsvarer den koniske innerflate av hylsen, som på kjent måte er fremstilt av kunststoff. Derved blir det trykk utsprengningslegemet øver på hylsen, fordelt jevnt over utsprengningslegemets omkrets. In order to now obtain an expandable plug that can be used for fastening screws of any type, it is proposed according to the invention to produce the plug's bursting body from a tough, hard and age-resistant plastic. In this connection, it is essential that the conical outer surface of the bursting body corresponds to the conical inner surface of the sleeve, which is produced in a known manner from plastic. Thereby, the pressure exerted by the bursting body on the sleeve is distributed evenly over the circumference of the bursting body.
Ved anvendelsen av et utsprengningslegeme av seigt, hårdt og eldebestandig kunststoff oppnås i forhold til de kjente utsprengningslegemer av metall den for-del at utsprengningslegemets gjenger ved tiltrekningen av festeskruen presser seg fast på skruegj engene på grunn av mot-trykket fra hylsen. Utsprengningslegemet ifølge oppfinnelsen får altså en forspen-ning som betinger en sikring mot løsning av festeskruen særlig ved rystning av den fastgjorte gjenstand. Dessuten blir der oppnådd et usedvanlig fast hold for skruen i utsprengningslegemets gjenger. When using a bursting body made of tough, hard and age-resistant plastic, compared to the known bursting bodies made of metal, the advantage is achieved that the threads of the bursting body, when the fastening screw is tightened, press firmly onto the screw threads due to the counter pressure from the sleeve. The bursting body according to the invention thus receives a pre-tension which conditions a safeguard against loosening of the fastening screw, particularly when the attached object is shaken. In addition, an exceptionally firm hold is achieved for the screw in the threads of the bursting body.
Det er hensiktsmessig om utsprengningslegemet er forsynt med langsgående It is appropriate if the bursting body is provided with longitudinal
utvendige spor, som føringsribber på den koniske innerflate av den utvidbare hylse griper inn i. For at utsprengningslegemet ikke skal kunne falle ut av hylsen eller bli skjøvet ut ved innføring av festeskruen, er føringsribbene forlenget utenfor enden av hylsen og bøyet om innover, slik at de leg-ger seg mot utsprengningslegemets endeflate. external grooves, into which guide ribs on the conical inner surface of the expandable sleeve engage. In order to prevent the bursting body from falling out of the sleeve or being pushed out when the fixing screw is inserted, the guide ribs are extended beyond the end of the sleeve and bent inwards, so that they lie against the end surface of the explosive body.

Pluggen på fig. 1 består av den utvidbare hylse 4 og utsprengningslegemet 2. Legemet 2 er utformet med muttergjenger for en skruebolt 1. Hylsen 4 og legemet 2 er fremstilt av et seigt, hårdt og eldebestandig kunststoff. For at utsprengningslegemet 2 ikke skal kunne dreie seg med under innskruning av festeskruen, er det forsynt med langsgående utvendige spor 3, 3' som ribber 5, 5' på innsiden av hylsen 4 griper inn i. Etter innsetning av utsprengningslegemet 2 i den utvidbare hylse The plug in fig. 1 consists of the expandable sleeve 4 and the bursting body 2. The body 2 is designed with a nut thread for a screw bolt 1. The sleeve 4 and the body 2 are made of a tough, hard and age-resistant plastic. In order for the bursting body 2 not to be able to turn while screwing in the fixing screw, it is provided with longitudinal external grooves 3, 3' into which ribs 5, 5' on the inside of the sleeve 4 engage. After inserting the bursting body 2 in the expandable sleeve

utenfor utsprengningslegemets endeflate, ombøyet innover på termisk vei. outside the end surface of the explosive body, bent inward on the thermal path.
Skal en gjenstand festes med treskruer Should an object be fixed with wood screws
til murverk, betong eller lignende, blir utsprengningslegemet 2 utført med muttergjenger 9 for treskruer. Fig. 2 viser en plugg for masonry, concrete or the like, the bursting body 2 is made with nut threads 9 for wood screws. Fig. 2 shows a plug
