Description

DK 174343 B1 i Nærværende opfindelse angår en wirelås for indbyrdes fastlåsning af to wirestrækninger, der i gensidig kontakt krydser hinanden, hvilken wirelås omfatter en U-formet part for optagelse af den ene wirestrækning, og en over-5 ligger beregnet for optagelse i den U-formede part ovenpå wirestrækningen heri, og hvor overliggerens ene ende har en bueform beregnet til at ligge ovenpå den anden wirestrækning, når denne placeres op mod den U-formede part samt et låseelement til placering i en åbning i benene af 10 den U-formede part for fastklemning af overliggeren og den herunder liggende første wirestrækning i den U-formede part, hvorved overliggeren samtidig med sin bueformede del fastklemmer den anden wirestrækning mod den første til indbyrdes sammenlåsning af disse.The present invention relates to a wire lock for mutually locking two wire stretches which cross each other in mutual contact, which wire lock comprises a U-shaped part for receiving one wire stretch, and an over-5 is intended for receiving in the U -shaped part on top of the wire stretch therein, and wherein one end of the cross member has an arcuate shape intended to lie on top of the other wire stretch when this is placed up against the U-shaped part and a locking element for placement in an opening in the legs of the U-shaped part for clamping the cross member and the underlying first stretch of wire in the U-shaped part, whereby the cross member simultaneously with its arcuate part clamps the second stretch of wire against the first for interlocking these.

En wirelås af ovennævnte art er kendt fra dansk patentskrift DK 164 968 B, hvilken wirelås udmærker sig ved at forenkle og lette håndteringen ved fastgørelsen af en wire på stykgods. Wirelåsen kan således samles og åbnes 20 blot ved brug af en hammer til forskel fra tidligere kendte wirelåse bestående af en U-formet bøjle, hvor nedover der kan sættes et åg, der fastspændes med møtrikke.A wire lock of the above kind is known from Danish patent specification DK 164 968 B, which wire lock is distinguished by simplifying and facilitating the handling when attaching a wire to piece goods. The wire lock can thus be assembled and opened simply by using a hammer, unlike previously known wire locks consisting of a U-shaped bracket, where a yoke can be fastened downwards, which is fastened with a nut.

Wirelåse benyttes typisk ved lastning og losning af styk-25 gods, oftest under vanskelige betingelser og i et aggressivt miljø. Som eksempel kan nævnes transport af rør til borerigge og olieplatforme, samt til olie- og gasledninger på havbunden hvor rørene losses fra skib i åben farvand. Det er her specielt afgørende, at wirelåsen er hur-30 tig og enkel at betjene. Under de forhold er det vanskeligt at stå med en skruenøgle og åbne en wirelås. Overordnet er det naturligvis helt afgørende, at wirelåsen låser wiren i et sikkert greb. Springer wirelåsen op, kan det få katastrofale følger for de mennesker, der befinder 35 sig i nærheden, eller godset falder i vandet og synker til bunds.Wire locks are typically used when loading and unloading piece-goods, most often under difficult conditions and in an aggressive environment. Examples include the transport of pipes to drilling rigs and oil platforms, as well as to oil and gas pipelines on the seabed where the pipes are unloaded from ships in open waters. It is especially crucial here that the wire lock is quick and easy to operate. Under those conditions, it is difficult to stand with a wrench and open a wire lock. Overall, it is of course absolutely crucial that the wire lock locks the wire in a secure grip. If the wire lock pops up, it can have catastrophic consequences for the people who are nearby, or the goods fall into the water and sink to the bottom.

For en forsvarlig fastlåsning er det afgørende, at wirer-ne er strammet godt til i låsen før fastspændingen. Såfremt wirerne ikke er strammet tilstrækkeligt, kan den 5 overliggende wire ved wirelåsen ifølge dansk patentskrift DK 164 968 B i uheldigste tilfælde skride ud af låseindgreb.For a secure locking, it is crucial that the wires are tightened well in the lock before clamping. If the wires are not tightened sufficiently, the overlying wire at the wire lock according to Danish patent specification DK 164 968 B can in unfortunate cases slip out of locking engagement.

Ved opfindelsen er det indset, at man kan forbedre sik-10 kerheden ved wirelåse af den i indledningen angivne art ved, at overliggerens bueformede ende fortsættes i to ben, der strækker sig ned på hver side af den første wi-restrækning, fortrinsvis en strækning større end wirens radius. Ved lukning af wirelåsen er det dermed sikret, at 15 den overliggende wirestrækning effektivt hindres i at glide ud af låseindgreb, selv om wirerne skulle være lidt løse. Når benene strækker sig ned forbi midten af den underliggende wire, dvs. svarende til, at benene har en længde, der er større end wirens radius, opnås en meget 20 sikker fastholdelse.By the invention it is realized that the security of wire locks of the type indicated in the introduction can be improved by continuing the arcuate end of the cross member in two legs extending down on each side of the first wire line, preferably a line greater than the radius of the wire. When closing the wire lock, it is thus ensured that the overlying wire stretch is effectively prevented from slipping out of locking engagement, even if the wires should be slightly loose. When the legs extend down past the center of the underlying wire, i.e. corresponding to the legs having a length greater than the radius of the wire, a very secure holding is obtained.

For yderligere forenkling og sikring af wirelåsen kan der på overliggeren fastgøres en bøjle, der med sin ene ende er fastgjort ved overliggerens bagende og med sin anden 25 ende er fastgjort til den bueformede del, og hvor bøjlen er udformet, så låseelementet uhindret kan passere gennem dette. Bøjlen har således to formål, nemlig at styrke overliggeren mod deformation samt lette indføring af låseelementet .For further simplification and securing of the wire lock, a bracket can be attached to the cross member, which is attached at one end to the rear end of the cross member and with its other end attached to the arcuate part, and where the bracket is designed so that the locking element can pass through this. The bracket thus has two purposes, namely to strengthen the cross member against deformation and to facilitate insertion of the locking element.

Til fastholdelse af låseelementet benyttes hensigtsmæssigt en låsesplit, der med det ene ben er ført gennem et hul i en sideflig på overliggeren. Herved er låseelementet umiddelbart tilgængelig.To hold the locking element, a locking split is expediently used, which with one leg is passed through a hole in a side flap of the cross member. This makes the locking element immediately accessible.

For brugen af wirelåsen er det vigtigt, at alle dens dele er let tilgængelige, hvilket opnås med en udførselsform, hvor den U-formede part, overliggeren og låseelementet er sammenholdt med en tråd ført gennem den ene åbning i den 5 U-formede part og fastgjort under låseelement i en langsgående udsparing. Låsens enkelte dele er således lige for hånden.For the use of the wire lock, it is important that all its parts are easily accessible, which is achieved with an embodiment in which the U-shaped part, the cross member and the locking element are held together with a wire passed through one opening in the 5 U-shaped part and fastened under locking element in a longitudinal recess. The individual parts of the lock are thus at hand.

En udførselsform for opfindelsen skal i det følgende be-10 skrives nærmere under henvisning til medfølgende tegning.An embodiment of the invention will be described in more detail below with reference to the accompanying drawing.

På tegningen viser: fig. 1 en samling af to wirestrækninger med en wirelås ifølge opfindelsen, 15 fig. 2 overliggeren af wirelåsen set i perspektiv, fig. 3 overliggeren set direkte ovenfra, og 20 fig. 4 viser wirelåsen i adskilt stand.In the drawing: fig. 1 shows an assembly of two wire stretches with a wire lock according to the invention, fig. 2 shows the crossbar of the wire lock seen in perspective, fig. 3 the cross member seen directly from above, and fig. 4 shows the wire lock in disassembled condition.

Som det fremgår af tegningens fig. 1, omfatter wirelåsen tre hovedbestanddele, nemlig en U-formet part 1, en overligger 2, et låseelement 3 her udformet som en kile.As can be seen from FIG. 1, the wire lock comprises three main components, namely a U-shaped part 1, a cross member 2, a locking element 3 here formed as a wedge.

Som det fremgår af tegningens fig. 2 og 3, består overliggeren 2 af to stænger 4, der ved overliggerens bagende går over i to sideflige 5, Fortil er stængerne formet i en bue 6, der i sin hulhed kan rumme en wirestrækning.As can be seen from FIG. 2 and 3, the cross member 2 consists of two rods 4, which at the rear end of the cross member merge into two side tabs 5. At the front, the bars are formed in an arc 6, which in its cavity can accommodate a wire stretch.

30 Yderenden af buen fortsætter i to ben 7 med en indbyrdes afstand svarende til tykkelsen af en wire.30 The outer end of the arch continues in two legs 7 with a mutual distance corresponding to the thickness of a wire.

I fig. 1 er vist, hvorledes to wirestrækninger fra en wire, der i et sling er lagt om stykgods, låses med wirelå-35 sen. Ved monteringen er wirelåsen adskilt i sine bestanddele som vist i fig. 4. Den U-formede part 1 sættes om- DK 174343 B1 4 kring wirestrækningen 8, så den med den ene ende, forenden, sidder op mod den anden wirestrækning 9. Herefter føres overliggeren 2 ind i den U-formede part 1, idet sidefligene 5 ligger an mod bagkanten af den U-formede 5 part. Den buede del 6 kommer herved til at gå over wirestrækningen 9, og hvor benene passerer ned på hver sin side af den underliggende wirestrækning 8. Overliggeren 2 låses ved, at kilen 3 med en hammer drives gennem åbninger 10 i hver side af den U-formede part 1. Kilen 3, der 10 er formet af et stykke bukket pladejern, er med en låsesplit 11 hindret i at falde ud. Låsesplitten er her bukket af en tråd i U-form, hvor det ene ben 12 er ført gennem et hul 13 i den ene sideflig 5 på overliggeren. Låsesplitten er hindret i at falde ud ved, at yderenden af 15 benet 12 har en udbukning 14.In FIG. 1 shows how two wire stretches from a wire laid around a piece of wire in a sling are locked with the wire lock. During assembly, the wire lock is separated into its components as shown in fig. 4. The U-shaped part 1 is turned around the wire section 8 so that it with one end, the front end, sits up against the other wire section 9. Then the cross member 2 is inserted into the U-shaped part 1, the side flaps 5 abut against the trailing edge of the U-shaped 5 part. The curved part 6 hereby passes over the wire section 9, and where the legs pass down on each side of the underlying wire section 8. The cross member 2 is locked by the wedge 3 being driven with a hammer through openings 10 in each side of the U- shaped part 1. The wedge 3, which is 10 formed by a piece of bent sheet iron, is prevented from falling out with a locking split 11. The locking pin is here bent by a wire in a U-shape, where one leg 12 is passed through a hole 13 in one side tab 5 of the cross member. The locking pin is prevented from falling out by the outer end of the leg 12 having a bulge 14.

Overliggeren 2 er på midten med et stykke tråd 15 forbundet til kilen 3. Tråden er ført gennem den ene åbning 10 i den U-formede part 1 og fastgjort indvendig i kilen.The cross member 2 is connected in the middle by a piece of wire 15 to the wedge 3. The wire is passed through one opening 10 in the U-shaped part 1 and fastened inside the wedge.

20 Herved hænger de tre dele sammen, hvilket letter brugen af wirelåsen.20 Hereby the three parts are connected, which facilitates the use of the wire lock.

For forstærkning af overliggeren er på der på dens overside fastgjort en bøjle 16. Bøjlen afstiver overliggerens 25 bueformede ende og dermed sikres, at den ikke ved overbelastning bliver rettet ud, så den tværgående wirestrækning 9 bliver rykket ud.To reinforce the cross member, a bracket 16 is attached to its upper side. The bracket braces the arcuate end of the cross member 25 and thus ensures that it is not straightened out in the event of an overload, so that the transverse wire section 9 is pulled out.

Når kilen 3 sættes i, styres den under bøjlen 16 på over-30 liggeren, hvilket igen er med til at lette anbringelsen af såvel overliggeren som kilen. Tråden 15, der i virkeligheden er relativ kort, lejrer sig ved kilens indføring oppe i dennes hulhed, hvor der ligger beskyttet mod overrivning .When the wedge 3 is inserted, it is guided under the bracket 16 on the overhead 30, which in turn helps to facilitate the placement of both the cross member and the wedge. The wire 15, which is in fact relatively short, settles at the insertion of the wedge up into its cavity, where it is protected against tearing.

Med opfindelsen er der således frembragt en wirelås, der er enkelt og sikker i betjeningen og samtidig yder høj sikkerhed mod, at låsningen af wirestrækningerne brydes op.With the invention, a wire lock is thus produced which is simple and secure in operation and at the same time provides high security against the locking of the wire sections being broken.
