Description

Foreliggende oppfinnelse angår en stropp av den type som anvendes som koplingsorgan mellom en lofte- eller annen håndteringsanordning og gods, som eksempelvis skal lastes eller losses ved hjelp av anordningen. Koplingsorganet er i form av en slynge, som består dels av en kjerne av en eller flere trådbunter, dels av et rundt kjernen anbrakt beskyttelsesdekke. The present invention relates to a strap of the type that is used as a connecting device between a loft or other handling device and goods, which, for example, are to be loaded or unloaded using the device. The coupling device is in the form of a sling, which consists partly of a core of one or more wire bundles, partly of a protective cover placed around the core.

Beskyttelsesdekket på tidligere kjente slynger har fremkommet The protective cover on previously known slings has appeared

ved at et bånd av et boyelig materiale og med en hensiktsmessig bredde har blitt anbrakt rundt kjernen, og båndets lengdekanter har innbyrdes blitt forent ved hjelp av en som. Denne igjensying av båndet i lengderetningen er et tidskrevende arbeide og den fremkomne som er tross sterke materialer slyngens svakeste del og går altfor tidlig i stykker under påvirkning av de store påkjenninger og den hårdhendte behandling slyngen utsettes for under anvendelsen. in that a band of a flexible material and of an appropriate width has been placed around the core, and the longitudinal edges of the band have been mutually joined by means of a This re-sewing of the band in the longitudinal direction is a time-consuming job and the result is, despite strong materials, the sling's weakest part and breaks far too early under the influence of the great stresses and the harsh treatment the sling is subjected to during use.

For å eliminere de ovenstående ulemper, er det tilveiebrakt To eliminate the above disadvantages, it is provided

en stropp ifolge oppfinnelsen som karakteriseres ved at beskyttelsesdekket består av en slange (eller ror) med ubrutt, somlos vegg. a strap according to the invention which is characterized by the protective cover consisting of a hose (or rudder) with an unbroken, seamless wall.

Oppfinnelsen skal i det folgende beskrives under henvisning The invention shall be described below by reference

til et på vedlagte tegninger vist utfdrdseseksempel. Fig. 1 viser en perspektivskisse av en kjerne dannet av en trådbunt. Fig. 2 viser en perspektivskisse av et beskyttelsesdekke for den i fig, 1 viste kjerne. Fig. 3 viser den ferdige stropp. Fig. 4 viser en seksjon langs linjen IV-IV i fig. 3. to a design example shown on the attached drawings. Fig. 1 shows a perspective sketch of a core formed by a wire bundle. Fig. 2 shows a perspective sketch of a protective cover for the core shown in Fig. 1. Fig. 3 shows the finished strap. Fig. 4 shows a section along the line IV-IV in fig. 3.

Den i fig. 3 viste, ferdige stropp 1 er av det slag som anvendes som koplingsorgan mellom en ikke nærmere vist lofte- eller annen håndteringsanordning og gods som eksempelvis skal lastes eller losses ( eller draes) ved hjelp av anordningen. Stroppen 1 er i form av en endelds slynge av et boyelig materiale. Slyngen består av dels en kjerne 2 av en eller flere trådbunter 3, bare en er for enkelhets skyld vist i fig. 1. Trådbuntenes 3 begge ender 4 er hensiktsmessig innbyrdes forenet, f.eks. knyttet sammen. Slyngen består videre av et rundt kjernen 2 anbrakt beskyttelsesdekke, som ifolge oppfinnelsen består av en slange 5 (eller ror) med ubrutt, somlos vegg 6, fig. 4. The one in fig. 3 shown, finished strap 1 is of the type used as a connecting device between a loft or other handling device, not shown in detail, and goods which, for example, are to be loaded or unloaded (or dragged) with the help of the device. The strap 1 is in the form of a continuous loop of a flexible material. The loop consists partly of a core 2 of one or more wire bundles 3, only one is shown in fig. for simplicity. 1. Both ends 4 of the wire bundles 3 are appropriately joined together, e.g. Tied together. The sling further consists of a protective cover placed around the core 2, which according to the invention consists of a hose 5 (or rudder) with an unbroken, somless wall 6, fig. 4.

En slik slange 5 kan anbringes på ulike måter rundt kjernen 2, men de måter som okonomisk og praktisk er anvendbare utgjor ingen del av foreliggende soknad. Slangen 5 dekker hele kjernen 2 og av slangens 5 ender er den enen enden 7 innskutt i den andre enden 8. Endene 7 og 8 kan også være innbyrdes forenet kant i kant. Slangen 5 har hensiktsmessig en slik lengde i forhold til kjernen 2, at den folder seg ved tverrynking og således er lenger enn slyngens omkrets, hvorved slangen henholdsvis roret kan anpasse seg til de lengdeforandringer som stroppen underkastes ved anvendelsen. Such a hose 5 can be placed in various ways around the core 2, but the ways that are economically and practically applicable do not form part of the present application. The hose 5 covers the entire core 2 and of the ends of the hose 5, one end 7 is inserted into the other end 8. The ends 7 and 8 can also be mutually joined edge to edge. The hose 5 appropriately has such a length in relation to the core 2 that it folds when transversely wrinkled and is thus longer than the circumference of the sling, whereby the hose or the rudder can adapt to the changes in length to which the strap is subjected during use.

Løftestroppen ifølge oppfinnelsen kan fremstilles på flere forskjellige måter. En enkel måte er først å avkappe et stykke bøyelig, sømløst slange- eller rørmateriale i egnet lengde, f.eks. en vevet tekstilslange av polyestergarn. For enkelhets skyld vil den fortsatte beskrivelse referere til en slik tekstilslange, men fremgangsmåten kan utøves også med andre slange- The lifting strap according to the invention can be produced in several different ways. A simple way is to first cut a piece of flexible, seamless hose or pipe material to a suitable length, e.g. a woven textile hose made of polyester yarn. For the sake of simplicity, the continued description will refer to such a textile hose, but the method can also be carried out with other hoses

eller rørmaterialer. Tekstilslangen skal ha en noe lenger lengde enn omkretslengden av den blivende løftestropp, slik at slangens ender siden kan innskytes i hverandre på den måte som er vist i fig. 3 i beskrivelsen. Slangen tres deretter over en tynn stang og trykkes kraftig sammen i lengderetningen, slik at slangen folder seg som en belg og i sammentrykket tilstand får en lengde som er en brøkdel av den blivende stropps omkretslengde.' Deretter av-kappes et garn- eller fiberknippe av f.eks. polyesterfibermateri-ale, i en slik lengde at garn- eller fiberknippestykket kan tres et nødvendig antall omganger, f.eks. 15 - 20 omganger gjennom slangen for å danne en kjerne med den for den blivende løfte-stropps nødvendige lengde. Ved hjelp av en egnet nålformet verk-tøy trer man deretter garn- eller fiberknippestykket omgang etter omgang gjennom det sammenfoldede slangestykke for in situ å danne løftestroppens kjerne, som derved får form av en trådbunt. Eventuelt kan man tre flere garn eller fiberknippestykker parallelt med hverandre gjennom slangestykket for på den måte å danne en trådbunt med flere paralleltløpende deler, hvorved hver del i denne trådbunt løper uavbrutt etter omgang gjennom løftestroppens hylster. Noen forankring av trådbuntens ender kreves ikke hvis trådbuntens del eller deler strekker seg f.eks. or pipe materials. The textile hose must have a somewhat longer length than the circumferential length of the remaining lifting strap, so that the ends of the hose can later be inserted into each other in the manner shown in fig. 3 in the description. The hose is then threaded over a thin rod and strongly compressed in the lengthwise direction, so that the hose folds like a bellows and in the compressed state has a length that is a fraction of the circumferential length of the remaining strap.' A yarn or fiber bundle is then cut off, e.g. polyester fiber material, in such a length that the yarn or fiber bundle piece can be threaded a necessary number of turns, e.g. 15 - 20 turns through the hose to form a core of the required length for the future lifting strap. With the help of a suitable needle-shaped tool, the piece of yarn or fiber bundle is then threaded round after round through the folded piece of hose to form the core of the lifting strap in situ, which thereby takes the form of a bundle of wire. Optionally, one can thread several pieces of yarn or fiber bundles parallel to each other through the hose piece in order to form a wire bundle with several parallel running parts, whereby each part in this wire bundle runs uninterrupted after one turn through the sleeve of the lifting strap. Any anchoring of the wire bundle ends is not required if the wire bundle part or parts extend e.g.

10 - 25 omganger gjennom stroppens hylster. Sluttelig dras den ovenfor angitte tynne stang ut av det sammenfoldede slange stykke, og slangestykket strekkes ut i sin fulle lengde, hvorved endene tres i hverandre på den i fig. 3 viste måte. Hensiktsmessig kan man deretter sy sammen slangeendene r.ed hverandre ved hjelp av noen sting som strekker seg i stroppens om-kretsretning, slik at kjernen fremdeles er fri i forhold til hylstret. 10 - 25 turns through the strap's sleeve. Finally, the above-mentioned thin rod is pulled out of the folded piece of hose, and the piece of hose is stretched out to its full length, whereby the ends are threaded together on the one in fig. 3 shown way. Appropriately, the hose ends can then be sewn together using a few stitches that extend in the circumferential direction of the strap, so that the core is still free in relation to the casing.

Den ovenfor beskrevne fremstillingsmetode kan selv-sagt mekaniseres, men de mekaniserte metoder bygger på samme prinsipp, dvs. at kjernen dannes in situ i et i lengderetningen sammentrykket bøyelig, slange- eller rørformet materialstykke. The manufacturing method described above can of course be mechanized, but the mechanized methods are based on the same principle, i.e. that the core is formed in situ in a flexible, hose- or tube-shaped piece of material compressed in the longitudinal direction.
