Description

szolvsz-7 2. paträdningen av bomrullen på pappersbommen. De olika manuella monteringsmomenten är tidskrävande och därmed kostsamma. szolvsz-7 2. the padding of the boom roll on the paper boom. The various manual assembly steps are time consuming and thus costly.

Det är sålunda ett ändamål med uppfinningen att tillhandahålla en rullagrings- - anordning, företrädesvis för användning i en skrivmaskin eller liknande kontorsmaskin, vilken enkelt och snabbt kan sammansättas och monteras pa tillhörande lagringsaxel. Ändamålet uppnås vid en anordning som uppvisar de i efterföljande patentkrav angivna särdragen.It is thus an object of the invention to provide a roll storage device, preferably for use in a typewriter or similar office machine, which can be easily and quickly assembled and mounted on the associated storage shaft. The object is achieved with a device which has the features specified in the following claims.

Ett utföringsexempel av uppfinningen, tillämpad i en skrivmaskin, skall nu beskrivas under hänvisning till bifogade ritning, på vilken fig. 1 ien sprângvy visar de en bomrulle i skrivmaskinen bildande delarna och fig. 2 i ett tvärsnitt visar en komplett bomrulle. Fig. 3 visar ett tvärsnitt genom en på en pappersbom monterad bomrulle.An embodiment of the invention, applied in a typewriter, will now be described with reference to the accompanying drawing, in which Fig. 1 is an exploded view showing the parts forming a boom roll in the typewriter and Fig. 2 in a cross section shows a complete boom roll. Fig. 3 shows a cross section through a boom roller mounted on a paper boom.

Fig. 4, slutligen, är en sidovy av den i fig. 3 visade anordningen. I Som framgår i fig. l består en enligt uppfinningen utförd pappersbomrulle 10 av endast tva delar, nämligen en själva rullen bildande plasthylsa ll och en lagrings- hylsa 12 på vilken plasthylsan är lagrad. Plasthylsan kan vara överdragen med ett gummiskikt, men i exemplet föredrages ett skikt av polyuretan 13. Polyuretanskiktet kan lätt paföras genom ett gjutningsförfarande. Plasthysan ll är vid sina ändar utformad med ringformiga ansatser 14, 15 vilka avgränsar en inre cylindrisk yta 16 medelst vilken plasthylsan är avsedd att uppbäras av en motsvarande yttre cylindrisk yta 17 pâ lagringshylsan 12.Fig. 4, finally, is a side view of the device shown in Fig. 3. As can be seen in Fig. 1, a paper boom roll 10 made according to the invention consists of only two parts, namely a plastic sleeve 11 forming the roll itself and a storage sleeve 12 on which the plastic sleeve is mounted. The plastic sleeve may be coated with a rubber layer, but in the example a layer of polyurethane 13 is preferred. The polyurethane layer can be easily applied by a casting process. The plastic sleeve 11 is formed at its ends with annular projections 14, 15 which delimit an inner cylindrical surface 16 by means of which the plastic sleeve is intended to be supported by a corresponding outer cylindrical surface 17 on the storage sleeve 12.

För fixering av plasthylsan 11 vid lagringshylsan 12 är den sistnämnda försedd med en ringformig fläns 18 som är avsedd att samverka med den ena av ansatserna 14, 15 och vidare med en fjädrande tunga 19, vars i fig. 2 och 3 sett, uppàtriktade ände l9a är avsedd att samverka med den motsatta ansatsen. Detta framgår klart i fig. 3 som visar papparsbomrullen monterad pà en med en plan yta 20 försedd pappersbom 21. Med ytan 20 samverkar en likaledes plan yta 22 anordnad på lagringshylsan 12 för att förhindra att denna kan vridas relativt pappersbommen 21. Därigenom undvikas att den fjädrande tungan utsätts för vridningskrafter. I Montering av den beskrivna pappersbomrullen sker genom att lagringshylsan 12 införes i plasthylsan 11 sä langt att flänsen 18 anllgger mot exempelvis ansatsen 14. I omonterat tillstànd har därvid den uppskjutande delen l9a intagit ett läge beläget innanför den cylindriska ytan 17, se fig. 2. Storleken av den fjädrande tungans ned- böjning i fig. 2 liksom längden av tungans fria ände l9a är avpassade så att önskat friktionsmotständ uppkommer mellan tungan och peppersbommen 21 samtidigt som den fria änden sträcker sig in över ansatsen 15 utan att med sin uppâtriktade begränsninge- yta kontakta plasthylsan 11 och därmed påverka dennas fria rotation. Monteringen avslutas med att den sammansatta bomrullen enligt fig. 2 paskjutes pa pappers- bommen 21 med den ände först vid vilken flänsen 18 är belägen. Därvid hâlles szoßvøs-7 automatiskt plasthylsan ll och lagringshylsan 12 i sina korrekta inbördes lägen under monter-ingen. Vid slutet av päskjutningsrörelsen förs den fjädrande tungan 19 uppåt av den plana ytan 20 pa pappersbommen och tungans fria ände l9a intar sitt i fíg. 3 visade läge i vilket den läser plasthylsan axiellt vid lagrlngshylsan.For fixing the plastic sleeve 11 to the storage sleeve 12, the latter is provided with an annular flange 18 which is intended to co-operate with one of the shoulders 14, 15 and further with a resilient tongue 19, the upright end 19a of which, seen in Figs. is intended to cooperate with the opposite approach. This can be clearly seen in Fig. 3 which shows the paper boom roll mounted on a paper boom 21 provided with a flat surface 20. A similarly flat surface 22 arranged on the storage sleeve 12 cooperates with the surface 20 to prevent it from being rotatable relative to the paper boom 21. resilient tongue is subjected to torsional forces. Mounting of the described paper boom roll takes place by inserting the storage sleeve 12 into the plastic sleeve 11 so far that the flange 18 abuts against, for example, the shoulder 14. In the unassembled condition, the projecting part 19a has assumed a position located inside the cylindrical surface 17, see Fig. 2. The magnitude of the deflection of the resilient tongue in Fig. 2 as well as the length of the free end 19a of the tongue are adjusted so that the desired frictional resistance arises between the tongue and the pepper boom 21 at the same time as the free end extends over the shoulder 15 without its upright limiting surface. contact the plastic sleeve 11 and thereby affect its free rotation. The assembly ends with the composite boom roller according to Fig. 2 being slid onto the paper boom 21 with the end first at which the flange 18 is located. In this case, the plastic sleeve 7 and the storage sleeve 12 are automatically kept in their correct mutual positions during assembly. At the end of the pushing movement, the resilient tongue 19 is moved upwards by the flat surface 20 of the paper boom and the free end 19a of the tongue takes its place in fig. 3 in which it reads the plastic sleeve axially at the storage sleeve.

Som framgår av utföringsexemplet har genom uppfinningen antalet ingående . detaljer nedbringats samtidigt som monteringsarbetet underlättats väsentligt.As can be seen from the exemplary embodiment, the invention has the number included in the invention. details have been reduced while the assembly work has been significantly facilitated.
