tagbare del for å lette det begynnende brudd samt utrivning av delen.detachable part to facilitate the incipient breakage as well as the extraction of the part.
Det særegne ved trekkhempen er at tverrstykket er forsterket mot tverrgående bbyning mellom den fremre del og den bakre del ved hjelp av delen av den oppstående flens og innkrollingen som utgjor en del av og er anordnet på motstående sider av tverrstykket, sli!k at trekkhempen er avstivet langs hele sin lengde» The distinctive feature of the drawbar is that the crosspiece is reinforced against transverse bending between the front part and the rear part by means of the part of the raised flange and the curling which forms part of and is arranged on opposite sides of the crosspiece, so that the drawbar is braced along its entire length"
Trekkhempens fremre del kan være ytterligere forsterket ved en periferisk flens og dens bakre del kan også være avstivet ved en ytre fal sekant; samtidig kan den periferiske flens være en fortsettelse av fal sekanten. The drawbar's front part can be further reinforced by a circumferential flange and its rear part can also be stiffened by an outer false secant; at the same time, the circumferential flange can be a continuation of the false secant.
Disse og andre trekk, som også er angitt i kravene, vil bli nærmere forklart i det fblgende under henvisning til tegningen, på hvilken fig. 1 viser trekkhempen sett mot undersiden, fig- 2 viser et forstbrret snitt av lokket og trekkhempen, og fig. 3 viser den fremre ende av trekkhempen ifblge fig. 2 sett i retning av pilene 3, fig. 2. These and other features, which are also stated in the claims, will be explained in more detail below with reference to the drawing, in which fig. 1 shows the pull cord seen towards the underside, fig. 2 shows an enlarged section of the lid and the pull cord, and fig. 3 shows the front end of the pull cord according to fig. 2 seen in the direction of the arrows 3, fig. 2.
På fig. 2 angir 10 en vanlig boks med en trekkhempe ifblge oppfinnelsen* Boksen består av en serie 11 som har et lokk 13 som er påfalaet ved 12. Lokket 13 har en lokkflate 14 som går over i falsen 12. Innenfor lokkflaten 14 befinner seg den avrivbare del av lokket som er betegnet med 15. Mellom delene 14 og 15 forloper en svekningslinje 16. In fig. 2 indicates 10 a normal box with a pull handle according to the invention* The box consists of a series 11 which has a lid 13 which is folded at 12. The lid 13 has a lid surface 14 that goes into the fold 12. Within the lid surface 14 is the tear-off part of the lid which is denoted by 15. Between the parts 14 and 15 a weakening line 16 runs.
For å trykke inn en åpning langs sveknlngslinjen 16 og trekke av den avrj.vbare del 15 anvendes en trekkhempe 17 (fig. 1) eller 40 (fig. 3) som er stanset ut av en tynn metallplate og er festet til den avrivbare lokkdel 15 ved hjelp av en nagle 18 som er presset ut i ett stykke med lokkdelen 15. In order to press in an opening along the weakening line 16 and pull off the tear-off part 15, a pull tab 17 (fig. 1) or 40 (fig. 3) is used which is punched out of a thin metal plate and is attached to the tear-off lid part 15 by means of a rivet 18 which is pressed out in one piece with the lid part 15.
Trekkhempen 17 på fig. 1 består av en fremre del 19 og en bakre trekkdel 20 som er forbundet over et tverrstykke 21. Den bakre del 20 kan ha form av en finger-ring og har en åpning til fingeren. Dens indre kant rundt åpningen 22 er innkrbllet som vist ved 23, fig. 2. Utvendig er ringen falset eller innkrbllet således at der dannes en falsekant 24?fig. 1. Innkrbllingen 23 og fal sekanten 24 motes på undersiden for at skarpe kanter skal unngås og ringen samtidig gjbres stiv. The drawstring 17 in fig. 1 consists of a front part 19 and a rear pull part 20 which are connected over a cross piece 21. The rear part 20 can have the shape of a finger ring and has an opening for the finger. Its inner edge around the opening 22 is crimped as shown at 23, fig. 2. On the outside, the ring is folded or crimped so that a folded edge 24?fig. 1. The indentation 23 and the bevel secant 24 are fashioned on the underside to avoid sharp edges and at the same time make the ring rigid.
Den fremre del 19 har en kanal (ribbe) som i det vesent-lige omgir denne del og består av en oppstående, indre flens 26, The front part 19 has a channel (rib) which essentially surrounds this part and consists of a raised inner flange 26,
et ovre steg 27 og en ytre, nedhengende flens 28, se fig. 1. Flensen 28 som forlbper på hver side av den fremre del 19, er en fortsettelse av falsekanten 24. Den innvendige flens 26 avgrenser an upper step 27 and an outer, hanging flange 28, see fig. 1. The flange 28 which continues on each side of the front part 19 is a continuation of the folded edge 24. The internal flange 26 delimits
videre tverrstykket 21 på den ene side og innkrbllingen 23 avgrenser tverrstykket på den annen side. furthermore, the cross-piece 21 on one side and the indentation 23 delimit the cross-piece on the other side.
Ribben 26, 27, 28 omgir et nedsenket, plant festepartiThe rib 26, 27, 28 surrounds a sunken, flat fastening part
30 med en festeflate 31. Festeflaten 31 er avgrenset av en U-formet gjennomskjæring 32 som har åpningen forover mot nesen og avsluttes på hver side med ombbyninger 33. Innenfor gjennomskjær-ingen 32 har flaten 31 også et hull som naglen 18 er fort gjennom for påklinking, se fig«2. 30 with an attachment surface 31. The attachment surface 31 is delimited by a U-shaped cut-out 32 which has the opening forward towards the nose and is finished on each side with bends 33. Within the cut-out 32, the surface 31 also has a hole through which the rivet 18 is fast riveting, see fig«2.
Den fremre del 19 av trekkhempen ender helt foran i en nese 35 som, se særlig fig. 1, omfatter et avrundet midtparti 36 og ytre partier 37 som divergerer utover og bakover. Nesens av-rundede midtparti 36 folger svekningslinjen i lokket, se fig. 2, The front part 19 of the drawstring ends at the very front in a nose 35 which, see especially fig. 1, comprises a rounded central part 36 and outer parts 37 which diverge outwards and backwards. The rounded middle part 36 of the nose follows the weakening line in the lid, see fig. 2,
og har samme krumningsradius som denne. Det sentrale neseparti 36 vil derfor trykke på lokkdelen 15 langs svekningslinjen 16 når trekkhempen 17 svinges nppad. and has the same radius of curvature as this one. The central nose part 36 will therefore press on the lid part 15 along the weakening line 16 when the draw hem 17 is swung upwards.
Trekkhempens bakre del 20 som har form av en ring, er helt bakerst bbyet opp som vist ved 38 for at ringen lettere skal kunne gripes når trekkhempen 17 skal lbftes for åpning av boksen. The rear part 20 of the drawbar, which has the shape of a ring, is bent up at the very back as shown at 38 so that the ring can be more easily grasped when the drawbar 17 is to be lifted to open the box.
Boksen åpnes ved at ringen 20 lbftes. Derved vil trekkhempen 17 svinges om en tverrgående linje som ligger mellom avslut-ningene 33 av den U-formige gjennomskjæring 32 med det resultat at hele trekkhempen vil virke som en vektstang med vippepunkt i flaten 31 som er festet til lokket med naglen 18. Ved fortsatt loft-ing av trekkhempen 17 vil ringen komme så hbyt at brukeren får stuk-ket fingeren helt inn i ringen og nesen 35 og dens buede del 36 begynner å trykke på.lokkdelen 14 langs et stykke av svekningslinjen 16 (se fig. 2). Ved fortsatt lbfting av trekkhempen vil vekt-armens trykk mot lokkflaten bli så stort at svekningen sprekker og en begynnende åpning langs svekningslinjen finner sted. Når ringen så trekkes oppover og bakover folger hele lokkdelen 15 med langs svekningslinjen inntil den er helt revet av. The box is opened by the ring being 20 lbftes. Thereby, the drawbar 17 will be swung about a transverse line that lies between the ends 33 of the U-shaped cut-out 32 with the result that the entire drawbar will act as a barbell with a tipping point in the surface 31 which is attached to the lid with the rivet 18. By continuing lofting the pull strap 17, the ring will come so fast that the user gets his finger stuck all the way into the ring and the nose 35 and its curved part 36 starts to press on the lid part 14 along a part of the weakening line 16 (see fig. 2). With continued lbfting of the draw hem, the weight arm's pressure against the lid surface will become so great that the weakening cracks and an incipient opening along the weakening line takes place. When the ring is then pulled upwards and backwards, the entire lid part 15 follows along the weakening line until it is completely torn off.
Fig. 2 og 3 viser en mindre endring ved trekkhempen som er betegnet med 40. Trekkhempen 40 består, i likhet med trekkhempen 17, av en fremre del 41 og en bakre del 42 tiL å trekke i. Delene 41 og 42 er forbundet over et tverrstykke 43 som tilsvarer 21 på fig. 1. Da trekkhempens bakre del 42 er nbyaktig den samme som forklart ovenfor, er en nærmere beskrivelse unodvendig. Figs. 2 and 3 show a minor change to the drawbar which is denoted by 40. The drawbar 40, like the drawbar 17, consists of a front part 41 and a rear part 42 for pulling in. The parts 41 and 42 are connected via a cross piece 43 which corresponds to 21 in fig. 1. As the rear part 42 of the drawbar is almost the same as explained above, a further description is unnecessary.
Den fremre del 41 er avgrenset av en presset ribbe (kanal) 44 som sammen med tverrstykket 43 danner en omsluttende avstivning. Ribben 44 består av en innvendig flens 45, et steg 46 og en ytre, nedhengende flens 47. Flensenes 45 og 47 form frem- The front part 41 is delimited by a pressed rib (channel) 44 which, together with the cross piece 43, forms an enveloping bracing. The rib 44 consists of an internal flange 45, a step 46 and an external, hanging flange 47. The flanges 45 and 47 form
går tydelig av fig. 2 og 3. Flensen 45 avgrenser et plant feste-is clear from fig. 2 and 3. The flange 45 delimits a flat attachment

hvilken gjennomskjæring omslutter festeflaten 51. Den U-formede gjennomskjæring 50 avsluttes med to omboyninger 52 og som ligger tvers overfor hinannen. Flaten 51 har i midten et hull 53 for naglen 18. which cut-out encloses the attachment surface 51. The U-shaped cut-out 50 ends with two bends 52 which lie across from each other. The surface 51 has a hole 53 in the middle for the rivet 18.
