Description

Oppfinnelsen vedrører et apparat som gjør det lettere å transportere og avvikle en spole som er viklet med tråd eller et annet fleksibelt fiberjnateriale. Por enkelhetens skyld blir alt slikt materiale heretter generelt kalt "tråd". The invention relates to an apparatus which makes it easier to transport and unwind a coil which is wound with wire or other flexible fiber material. For the sake of simplicity, all such material is hereinafter generally referred to as "thread".

Det er vanlig å transportere en trådspole i en todelt beholder, som i en av endeveggene er forsynt med et hull eller et svekket område som lett kan fjernes for dannelse av et hull, gjennom hvilket tråd kan trekkes fra spolen mens denne fortsatt befinner seg i beholderen. Por at tyveri eller klussing med spolen skal hindres, blir de to beholderdeler vanligvis festet sammen ved hjelp av en separat utformet, avtagbar låseanordning, vanligvis en anordning som er frem-stilt av stål og omfatter en låskrok (toggle lock) på et kant-bånd. Slike låseanordninger er vanskelige å montere, da an-gripes av korrosjon og kan lett mistes. It is common to transport a spool of thread in a two-part container, one of the end walls of which is provided with a hole or weakened area that can be easily removed to form a hole through which thread can be pulled from the spool while it is still in the container . In order to prevent theft or tampering with the coil, the two container parts are usually fastened together by means of a separately designed, removable locking device, usually a device made of steel and comprising a toggle lock on an edge band . Such locking devices are difficult to install, as they are attacked by corrosion and can easily be lost.

En hensikt med foreliggende oppfinnelse er å tilveiebringe en todelt trådspolebeholder som omfatter bedrede organer for sammenlåsing av de to beholderdeler. One purpose of the present invention is to provide a two-part thread spool container which includes improved means for interlocking the two container parts.

Ifølge oppfinnelsen omfatter beholderen to separat utformede deler, som hver har en endevegg og perpendikulært på endeveggen en kontinuerlig omkrets-, eller sidevegg og hvor en av delene i sin sidevegg har et hull eller et' svekket område som lett kan fjernes for dannelse av et hull, for uttrekking av tråd fra en spole når denne befinner seg i beholderen, hvor de to- deler er tilpasset for sammenlåsing ved rotasjon av den ene delen i forhold til den andre og hvor delene er forsynt med en fjærbelastet pal og palkransmekanisme som tillater relativ dreining mellom' de to deler når disse er. sammenfestet og som, når de to delene er i fullt inngrep, According to the invention, the container comprises two separately designed parts, each of which has an end wall and perpendicular to the end wall a continuous peripheral or side wall and where one of the parts in its side wall has a hole or a weakened area which can be easily removed to form a hole , for the extraction of thread from a spool when this is in the container, where the two parts are adapted for interlocking by rotation of one part in relation to the other and where the parts are provided with a spring-loaded pawl and pawl ring mechanism that allows relative rotation between' the two parts when these are. joined together and which, when the two parts are fully engaged,

hindrer atskillelse av de to delene jved relativ rotasjon i motsatt retning med mindre den fjærbelastede palen er ført prevents separation of the two parts by relative rotation in the opposite direction unless the spring-loaded pawl is guided

Den bedrede trådspolebeholder har to viktige fordeler. For det første betyr det (forhold at de to beholderdeler bærer, en f jærbelastet pal og pjalkransmekanisme' for sammenlåsing av delene at det.ikke kjreves montering av en låseanordning og det er ingen fare for at. en låseanordning mistes. Palen og palkransen kan fremstilles av et hensikts-messig plastmateriale, slik at korrojsjon utelukkes. Dessuten vil pal- og palkransanordningen, når de to beholderdelene er festet sammen ved -dreining av1 den e,ne i forhold' til den andre, gi et hørbart signal når delene nærmer seg den stilling hvor de befinner seg i fullt inngrep.. The improved thread spool container has two important advantages. Firstly, the fact that the two container parts carry a spring-loaded pile and pile ring mechanism for locking the parts together means that there is no need to install a locking device and there is no danger of a locking device being lost. The pile and the pile ring can be manufactured of a suitable plastic material, so that corrosion is ruled out. Furthermore, when the two container parts are fastened together by turning one relative to the other, the pal and pal collar device will give an audible signal when the parts approach it position where they are in full engagement..

I den bedrede utførelsen er de to beholderdelerIn the improved version, they are two container parts

i skruegjengeforbindelse, men i enkelte tilfelle .kan delene festes sammen ved hjelp av en eller flere bajonettlåser. in a screw thread connection, but in some cases the parts can be fastened together using one or more bayonet locks.

Palen er fortrinnsvis dreibart montert på sideveggen av den ene beholderdelen og palkransen omfatter et flertall fordypninger i innbyrdes avstand rundt omkretsen over et område som strekker seg over minst en del av omkretsen av sideveggen av den ene beholderdelen. Den avgrensende vegg av hver fordypning mot hvilken palen vil få kontakt når de to beholderdelene skrus sammen er skråstilt slik at palen kan passere over begrensningsveggen mot fjærens'virkning•og ned i neste fordypning. En motstående vegg i hver fordypning har en slik form at den danner et anslag som hindrer at de to delene skrus fra hverandre med mindre palen manuelt bringes ut av inngrep med fordypningen mot fjærens virkning. Hver fordypning i palkransen har fortrinnsvis tilnærmet trekantform, hvor to vegger danner de nevnte begrensningsveggene og den tredje.vegg ligger på en felles omkrets med beholderen med motstående spiss av trekantfordypningen fjern fra palen. Den ende av palen som etter hvert går i inngrep med etter hverandre følgende fordypninger i palkransen når de to beholderdeler skrus sammen har fortrinnsvis komplementær form. The pile is preferably rotatably mounted on the side wall of the one container part and the pile rim comprises a plurality of recesses spaced around the circumference over an area that extends over at least part of the circumference of the side wall of the one container part. The delimiting wall of each depression against which the pawl will make contact when the two container parts are screwed together is inclined so that the pawl can pass over the limiting wall against the action of the spring and down into the next depression. An opposing wall in each recess is of such a shape that it forms a stop which prevents the two parts from being screwed apart unless the pawl is manually brought out of engagement with the recess against the action of the spring. Each recess in the pile ring preferably has an approximate triangular shape, where two walls form the aforementioned limiting walls and the third wall lies on a common circumference with the container with the opposite tip of the triangular recess remote from the pile. The end of the pawl which eventually engages with successive recesses in the pawl rim when the two container parts are screwed together preferably has a complementary shape.

Palen har fortrinnsvis formen av en fjærbelastet vektarm som er dreibart montert mellom et par støtter, som rager ut fra sideveggen på den beholderdel som bærer pålen The pile is preferably in the form of a spring-loaded weight arm which is rotatably mounted between a pair of supports, which project from the side wall of the container part carrying the pile

og som strekker seg i det veséntlige| parallelt med beholderaksen. Palens dreieakse forløper perpendikulært på beholderaksen. Palen og støttene er også fcjrtrinnsvis forsynt med huller eller spor som, i det minste jnår palen er i inngrep med en fordypning i palkransen, forløper i flukt og sikrer trådspolebeholderen mot klussing ve ei hjelp av en tråd og et blysegl eller et plastsegl e.l.. and which extends in the essential| parallel to the container axis. The axis of rotation of the pawl runs perpendicular to the axis of the container. The pile and the supports are also preferably provided with holes or grooves which, at least when the pile engages with a recess in the pile rim, run flush and secure the thread spool container against tangling with the help of a thread and a lead seal or a plastic seal or the like.

For at monteringsarbeidet skal lettes, benyttes en gjenging hvor sammenkopling kan skje flere steder. En av de to beholderdeler har fortrinnsvis en stopper i forbindelse med gjengen eller gjengene, som kommer i kontakt med en ende av gjengen eller gjengena for den andre beholderdel når de to delene er skrudd helt sammen. In order to make the assembly work easier, a thread is used where connection can take place in several places. One of the two container parts preferably has a stopper in connection with the thread or threads, which comes into contact with one end of the thread or threads of the other container part when the two parts are fully screwed together.

Den beholderdel som ikke har et hull eller et svekket område i endeveggen for uttrekking av tråd fra beholderen, er fortrinnsvis forsynt med et boss som står opp fra endeveggen og er koaksialt med hullet eller det svekkede The container part which does not have a hole or a weakened area in the end wall for the extraction of thread from the container is preferably provided with a boss that stands up from the end wall and is coaxial with the hole or the weakened

i in

området, når de to delene er skrudd sammen. Bosset har slik utvendig diameter at det passer tett i boringen for navet av en spole når spolen er anbragt i beholderen. Hullet gjennom hvilket tråden skal trekkes ut kan ha en avtagbar propp eller hette. area, when the two parts are screwed together. The boss has such an outside diameter that it fits snugly in the bore for the hub of a coil when the coil is placed in the container. The hole through which the thread is to be withdrawn may have a removable plug or cap.

Ved bruk vil den del av beholderen som har bosset ragende fra endeveggen danne nedre del av beholderen og den aksiale lengde av denne beholderdel er generelt, men ikke nødvendigvis, betydelig kortere enn den aksiale lengde av den andre delen. Nedre del av beholderen bærer hensikts-messig palkransen for pal- og palkransmekanismen. For enklere sammenskruing og oppskruing av beholderdelen kan nedre del ha flere ribber eller være ruglet på annen måte, slik at den lett kan holdes fast mellom en operatørs føtter, mens øvre beholderdel skrus til eller opp. In use, the part of the container which has the boss projecting from the end wall will form the lower part of the container and the axial length of this container part is generally, but not necessarily, significantly shorter than the axial length of the other part. The lower part of the container suitably carries the paling ring for the paling and paling ring mechanism. For easier screwing together and screwing up of the container part, the lower part can have several ribs or be ruffled in some other way, so that it can easily be held firmly between an operator's feet, while the upper container part is screwed on or up.

Fortrinnsvis er hver beholderdel et. støpt legeme av termoplast. Hensiktsmessige materialer omfatter polystyren, polypropylen og akrylnitril-butadienstyren-terpolymer. Palkransen er fortrinnsvis utformet i ett med den beholderdel som bærer den. Palen består fortrinnsvis også av støpt termoplast. Preferably, each container part is one. molded body of thermoplastic. Suitable materials include polystyrene, polypropylene and acrylonitrile-butadiene styrene terpolymer. The paling ring is preferably designed in one with the container part that carries it. The pallet preferably also consists of molded thermoplastic.

I tegningen omfatter cen todelte trådspolebeholderen en nedre del 1 av støpt termoplast med en endevegg \2 og perpendikulært på denne en kontinuerlig omkretsvegg 3 og i skruegjenget forbindelse med nedre del en øvre del 21 av støpt termoplast med en endevegg 22 og perpendikulært på denne-en kontinuerlig vomkretsvegg 23. Skrueforbindelsen mellom nedre del 1 og øvre del 21 opprettes ved e;n multi-start-gjenging 18 på nedre del. I tilslutning til disse gjenger er det anordnet et anslag som en gjenge av øvre del stanser mot når de to In the drawing, the two-part wire spool container comprises a lower part 1 of molded thermoplastic with an end wall \2 and perpendicular to this a continuous circumferential wall 3 and in screw-threaded connection with the lower part an upper part 21 of molded thermoplastic with an end wall 22 and perpendicular to this-a continuous rumen circuit wall 23. The screw connection between lower part 1 and upper part 21 is created by a multi-start thread 18 on the lower part. In connection with these threads, a stop is arranged against which a thread of the upper part stops when the two

delene er helt sammenskrudd.the parts are completely screwed together.

Rundt sideveggen 3 av nedre del 1 forløper en palkrans 4, som omfatter flere fordypninger 5 i innbyrdes avstand rundt omkretsen. En pal 24, som er fjærbelastet ved hjelp av en fjær 26, er dreibart montert på sideveggen 23 for øvre del 21 mellom et par stoppere 25. Hver fordypning 5 i palkransen 4 har tilnærmet trekantform, hvor begrensningsveggen 6 for hver fordypning, som palen 24 vil få kontakt mot når delene 1 og 21 skrus sammen, er skråstilt slik at den tillater palen å gli over begrensningsveggen mot fjærens 26 virkning og inn i neste fordypning. Begrensningsveggen 7 for hver fordypning har en slik form at den danner et anslag som hindrer de to deler fra å skrus opp med mindre palen fjernes manuelt fra fordypningen mot fjærens virkning.. Stopperne 25 er forsynt med huller 27 og palen 24 har et spor 28. Når palen er i inngrep med en fordypning 5 i palkransen 4, for-løper hullene og sporet i flukt, slik at beholderen kan for-segles mot klussing ved hjelp av en tråd og et blysegl, et plastsegl e.l. Around the side wall 3 of the lower part 1 runs a paling ring 4, which includes several recesses 5 at a distance from each other around the circumference. A pawl 24, which is spring-loaded by means of a spring 26, is rotatably mounted on the side wall 23 of the upper part 21 between a pair of stoppers 25. Each recess 5 in the pawl ring 4 has an approximately triangular shape, where the limiting wall 6 for each recess, like the pawl 24 will make contact with when the parts 1 and 21 are screwed together, is inclined so as to allow the pawl to slide over the limiting wall against the action of the spring 26 and into the next recess. The boundary wall 7 for each recess has such a shape that it forms a stop which prevents the two parts from being screwed up unless the pawl is removed manually from the recess against the action of the spring. The stoppers 25 are provided with holes 27 and the pawl 24 has a groove 28. When the pawl engages with a recess 5 in the pawl ring 4, the holes and the groove run flush, so that the container can be sealed against clogging by means of a thread and a lead seal, a plastic seal or the like.

Nedre del 1 har et rørformet boss 8, som rager opp fra endeveggen 12. Bosset har en slik utvendig diameter at det passer tett inn i boringen i navet for.en trådspole, Lower part 1 has a tubular boss 8, which protrudes from the end wall 12. The boss has such an external diameter that it fits snugly into the bore in the hub for a spool of thread,
