Opfindelsen angår en låseanordning til en container, og som omfatter en arm og en modpart, og hvor armen og modparten hver er forsynet med låselegemer, som selv er forsynede med huller, hvilken arm og modpart kan låses sammen ved hjælp af en U-5 formet hængelås med retlinet låsepind.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a locking device for a container, comprising an arm and a counterpart, each of which the arm and counterpart are provided with locking bodies which themselves are provided with holes, which arm and counterpart can be locked together by means of a U-shaped padlock with rectilinear locking pin.

Fra SE fremlæggelsesskrift nr. 441.820 kendes en låseanordning til en en container, og som udgøres af en bjælke. Anordningen har forankringsorganer, der indsættes i åbninger, der findes i containerens hjørnebeslag. Anordningen har et låsehåndtag, der 10 står i forbindelse med det ene forankringsorgan og kan dreje dette. Låsehåndtaget er i sin låste stilling indesluttet under et beskyttelsesskjold, som skulle mindske risikoen for opbrydning af selve låsen. Beskyttelsesskjoldet er dog ikke tilfredsstillende, fordi en tyv med sit værktøj for let kan nå 15 ind til de vitale dele, især hængelåsens bøjle. Det er heller ikke helt hensigtsmæssig, at låseanordningen skal afmonteres' helt for at give adgang til containeren, hvortil kommer at den er uhandy og meget tung. Ligeledes vil den kunne bruges på forskellige containere, da den ikke har nogen speciel tilknyt-20 ning til den enkelte container.SE Publication No. 441,820 discloses a locking device for a container and which is constituted by a beam. The device has anchoring means inserted into apertures located in the corner bracket of the container. The device has a locking handle which 10 communicates with one of the anchoring means and can rotate it. The lock handle is enclosed in its locked position under a protective shield, which should reduce the risk of breaking the lock itself. However, the protective shield is not satisfactory because a thief with his tool can easily reach 15 to the vital parts, especially the padlock hanger. Also, it is not entirely appropriate for the locking device to be completely removed to allow access to the container, in addition to being uncomfortable and very heavy. It can also be used on different containers as it has no special connection to the individual container.

Fra US patentskrift nr. 4.500.123 kendes et dørlåsearrangement til f.eks. lastbilers bagdøre. Låsearrangementet består af to rørstykker, der er fastgjort til hver sin halvdel af en dob- · beltdør. I enden af det ene rørstykke findes en kasseformet 25 del. Når låsen skal låses, føres et langt rør, hvis længde svarer til de to rørstykkers samlede længde, ind i de to rørstykker. På det lange rør er der fastgjort et pladestykke, der passer ind i en rille i den kasseformede del. I pladestykket findes der et hul, hvorigennem bøjlen på en hængelås kan ind-30 sættes. Når låsen skal låses, og pladestykket er placeret i rillen i den kasseformede del, kan hængelåsen føres ind i den kasseformede del og låses. Hængelåsen er nu placeret i den kasseformede del og er derved beskyttet mod oversavning og forskellige former for påvirkning med brækjern. Ydermere er 35 der inde i det lange rør et indre rør, der er frit roterbart.US Patent No. 4,500,123 discloses a door lock arrangement for e.g. trucks' back doors. The locking arrangement consists of two pieces of pipe, which are attached to each half of a double door. At the end of one of the tubes is a box-shaped part 25. When the lock is to be locked, a long pipe, the length of which corresponds to the total length of the two pipe pieces, is inserted into the two pipe pieces. On the long tube is attached a plate which fits into a groove in the box-shaped part. In the plate there is a hole through which the bracket on a padlock can be inserted. When the lock is to be locked and the plate is located in the groove in the box-shaped part, the padlock can be inserted into the box-shaped part and locked. The padlock is now placed in the box-shaped part and is thus protected against sawing and various types of impact with the fracture iron. Furthermore, inside the long tube is an inner tube which is freely rotatable.

DK 170428 B1 2DK 170428 B1 2

Det indre rør skal ved rotation besværliggøre oversavning af det lange rør. Dette dørlåsearrangement er ikke så hensigtsmæssigt, da hængelåsen ikke er tæt omsluttet af den kasseformede del, og da det lange rør skal fjernes helt fra låseanord-5 ningen, før dørene kan lukkes op. De resterende dele er dog fast monteret på selve døren. Det er ligeledes uhensigtsmæssigt, at hovederne på skruerne, skønt de er sikrede, er tilgængelige udefra, f.eks. for brækjern eller lignende.The inner tube must, by rotation, make it difficult to saw the long tube. This door locking arrangement is not so convenient since the padlock is not tightly enclosed by the box-shaped part and since the long pipe must be completely removed from the locking device before the doors can be opened. However, the remaining parts are fixed to the door itself. It is also inconvenient that the heads of the screws, although secured, are accessible from the outside, e.g. for fracture iron or the like.

Fra US patentskrift nr. 4.581.907 kendes en låseanordning, 10 hvor hængelåsens bøjle rager ud fra en låseblok og er beskyttet af beskyttelsesdele. Denne låseanordning virker ikke helt tilfredstillende, da låsebøjlen ikke er fuldstændig tildækket, hvorfor den er tilgængelig for bearbejdning med forskellige former for værktøj med det formål at bryde låsen op.US Patent No. 4,581,907 discloses a locking device 10, wherein the padlock of the padlock protrudes from a locking block and is protected by protective parts. This locking device does not work completely satisfactorily, as the locking bracket is not completely covered, which is why it is available for machining with various types of tools for the purpose of breaking the lock.

15 Fra US patentskrift nr. 3.744.280 kendes en låseanordning, som * delvis har midler til at forhindre overskæring eller opbrydning af hængelåsen. Konstruktionen er ikke umiddelbart i stand at kunne yde en rimelig sikkerhed.US Patent No. 3,744,280 discloses a locking device which * partially has means for preventing cutting or breaking of the padlock. The construction is not immediately capable of providing reasonable security.

Fra US patentskrift nr. 3.736.016 kendes en låseanordning til. 20 låsning af en anhængers bagdøre. Ved denne låseanordning er en hængelås anbragt inden i et hus, men huset er ikke tæt sluttende omkring hængelåsen.US Patent No. 3,736,016 discloses a locking device. 20 locking the back doors of a trailer. With this locking device, a padlock is disposed within a housing, but the housing is not tightly sealed around the padlock.

Fra US patentskrift nr. 4.106.315 kendes en låseanordning, som er omgivet af et hus. Ved denne låseanordning sidder låsebøj -25 len fast på den ene del af huset, hvilket bl.a. medfører, at låsen er svær at udskifte. Der er ikke tale om en hængelås i konventionel forstand, da bøjlen kan adskilles fuldstændigt fra låseblokken. Dele af låsebøjlen er retlinet, men selve låsebøjlen udgøres ikke af en retlinet låsepind. Når låseblokken 30 skal indføres i huset, sker det ved indføring i kun en retning. Denne låseanordning vil ikke være egnet til en klinke, da låsebøjlen skal passere ned gennem huller i låselegemerne samtidig med, at flere dele af selve huset skal passe sammen, DK 170428 B1 3 hvilket vil medføre., at delene enten skal produceres med meget små tolerancer eller, at delene vil blive meget følsomme over for deformationer som følge af stød eller slag.US Patent No. 4,106,315 discloses a locking device which is surrounded by a housing. With this locking device, the locking bracket -25 is fixed to one part of the housing, which ia. causes the lock to be difficult to replace. This is not a padlock in the conventional sense, as the hanger can be completely detached from the locking block. Parts of the locking bracket are rectilinear, but the locking bracket itself is not a rectilinear locking pin. When the locking block 30 is to be inserted into the housing, this occurs by insertion in only one direction. This locking device will not be suitable for a latch, as the locking bracket must pass down through holes in the locking bodies while several parts of the housing itself must fit together, which will cause the parts to be produced either with very small tolerances. or that the parts will become very sensitive to deformation due to shock or impact.

Formålet med opfindelsen er at tilvejebringe en låseanordning 5 af den indledningsvis nævnte art, og som foruden at reducere de ovennævnte ulemper muliggør en væsentligt forbedret beskyttelse mod indbrud.The object of the invention is to provide a locking device 5 of the kind mentioned above and which, in addition to reducing the above-mentioned disadvantages, enables a significantly improved protection against burglary.

Låseanordningen ifølge opfindelsen er ejendommelig ved de træk der er angivet i den kendetegnende del af krav 1. Herved op-10 nås, at det bliver så godt som umuligt at komme ind til hængelåsens sårbare dele, dvs. låsepinden, med f.eks. en nedstryger eller et brækjern, da låselegemerne og hængelåsens låsepind er tæt omsluttet af huset, når låseanordningen er låst. Der kan således anvendes låse med uhærdede låsepinde, da låse-15 pinden ikke er lastbærende, hvilket besværliggør indbrud. -Yderligere opnås ved at sikre fastgørelsesorganerne, at en tyv ikke fristes til at forsøge at bryde låseanordningen op ved at fjerne disse fastgørelsesorganer. Alle dele er fastgjort til selve containeren, og derved undgår man forskellige former for 20 løse stænger. Det er en yderligere fordel ved opfindelsen, at alle delene sidder fast på containeren, og kun hængelåsen kan aftages som løs del, når låseanordningen ikke er i brug.The locking device according to the invention is characterized by the features defined in the characterizing part of claim 1. Hereby it is achieved that it becomes almost impossible to access the vulnerable parts of the padlock, ie. the locking pin, with e.g. a throttle or a broken iron, since the locking members and padlock locking pins are tightly enclosed by the housing when the locking device is locked. Thus, locks with uncured locking pins can be used, since the locking pin is not load-bearing, which makes it difficult to break. - Further, by securing the fasteners, a thief is not tempted to attempt to break the locking device by removing these fasteners. All parts are attached to the container itself, thereby avoiding various forms of 20 loose bars. It is a further advantage of the invention that all parts are secured to the container and only the padlock can be removed as a loose part when the locking device is not in use.

Ifølge opfindelsen kan huset være kasseformet og helt aflukket på fire af sine seks sider og halvt aflukket på den femte og 25 åbent på den sjette side. Herved opnås at låseanordningen kun er tilgængelig fra én side, hvilket i en indbrudssituation gør det særlig vanskeligt at komme ind til hængelåsens vitale dele med forskellige værktøjer.According to the invention, the housing may be box-shaped and fully enclosed on four of its six sides and half enclosed on the fifth and 25 open on the sixth side. This ensures that the locking device is only accessible from one side, which in a burglary situation makes it particularly difficult to access the vital parts of the padlock with various tools.

En særlig hensigtsmæssig udformning af låseanordningen ifølge 30 opfindelsen er ejendommelig ved, at det i huset anbragte låselegeme er fastgjort til to af husets sider og til den femte sides kant; herved opnås at i hvert fald en væsentlig del af hængelåsen, når denne er i sin låseposition, vil befinde sig DK 170428 B1 4 inde i huset, hvor den er fuldstændig utilgængelig.A particularly convenient embodiment of the locking device according to the invention is characterized in that the locking body arranged in the housing is fixed to two sides of the housing and to the edge of the fifth side; Hereby it is achieved that at least a substantial part of the padlock, when in its locking position, will be located within the housing where it is completely inaccessible.

Endnu en udførelsesform for låseanordningen ifølge opfindelsen er speciel derved, at det af låselegemerne, som er anbragt i huset, danner et kammer heri, hvilket kammer, når der ses bort 5 fra hullet i låselegemet, kan være helt aflukket på fem sider, medens kammerets sjette side er åben; dette giver en yderligere sikkerhed.Yet another embodiment of the locking device according to the invention is special in that it forms a chamber therein of the locking members which is housed in the housing, which, when viewed 5 from the hole in the locking body, can be completely closed on five sides, while the chamber the sixth page is open; this provides additional security.

Det har ifølge opfindelsen vist sig fordelagtigt, hvis hængelåsens første indskydningsretning er parallel med og ikke 10 sammenfaldende med aksen af hullet gennem låselegemerne.It has been found advantageous according to the invention if the first insertion direction of the padlock is parallel to and does not coincide with the axis of the hole through the locking bodies.

Desuden kan ifølge opfindelsen de to låselegemer udgøres af tykke pladeformede emner, hvorhos den samlede tykkelse af disse emner kun er ganske lidt mindre end den største tykkelse, som hængelåsen kan gabe over; herved opnås at det bliver 15 meget besværligt for en person, der forsøger at vrikke låsen fra hinanden.In addition, according to the invention, the two locking members may be made of thick plate-shaped blanks, the total thickness of which blanks being only slightly smaller than the largest thickness over which the padlock can yaw; This results in the fact that it becomes very difficult for a person trying to break the lock.

Endnu en udførelsesform for låseanordningen ifølge opfindelsen er ejendommelig ved, at fastgørelsesorganerne omfatter skruer, som under låseanordningens montage på containeren kan 20 fastholdes ved den ende, der er modsat hovederne, f.eks. ved, at der i skruen er en indvendig sekskant; herved opnås, at selve hovederne på skruen bliver umulige at få fat på udefra med forskellige former for brækjern.Yet another embodiment of the locking device according to the invention is characterized in that the fastening means comprise screws which, during mounting of the locking device on the container, can be retained at the end opposite to the heads, e.g. know that in the screw there is an inner hexagon; This results in the actual heads of the screw becoming impossible to grasp from the outside with various types of brittle iron.

Fremdeles kan ifølge opfindelsen de som skruer udformede fast-25 gørelsesorganer være sikret mod oversavning ved hjælp af bøsninger, som er anbragt omkring skruernes skaft, hvorhos bøsningerne, selv om skruen er spændt, frit kan rotere, hvorhos * endvidere bøsningerne kan være undersænkede i afstandsstykkerne, medens modparten er en integrerende del af afstandsstyk-30 kerne; herved opnås, at hvis en person forsøger at save skrueskaftet over ved enten at save ned imellem de enkelte dele af låseanordningen eller ved at oversave selve delene, vil bøs- DK 170428 B1 5 ningen blot rotere, hvilket forhindrer oversavning af skruerne.Still, according to the invention, the screw-shaped fasteners can be secured against sawing by means of bushes arranged around the shaft of the screws, although the bushes, although the screw is tightened, can freely rotate, whereby the bushes can also be submerged in the spacers. whereas the counterpart is an integral part of the spacer core; Hereby it is achieved that if a person tries to cut the screw shaft over by either cutting down between the individual parts of the locking device or by oversaw the parts themselves, the bushing will simply rotate, preventing the sawing of the screws.

Endvidere kan ifølge opfindelsen bøsningerne være af hærdet stål eller af sintret hårdmetal. Herved opnås at selve skruen 5 kan fremstilles af et ret billigt materiale, medens bøsningerne kan gøres meget hårde. Små runde emner med konstant godstykkelse er meget nemme at fremstille i utroligt hårde materialer.Furthermore, according to the invention, the bushings may be of hardened steel or of sintered cemented carbide. This results in the fact that the screw 5 itself can be made of a fairly inexpensive material, while the bushings can be made very hard. Small round items with constant thickness are very easy to manufacture in incredibly hard materials.

Endelig kan ifølge opfindelsen hængelåsen hensigtsmæssigt have 10 en i hovedsagen kantet O-form, idet låsepinden i hovedsagen kan danne den ene af de fire sider i den kantede O-form.Finally, according to the invention, the padlock may conveniently have a substantially angular O-shape, the locking pin generally being able to form one of the four sides of the angular O-shape.

Opfindelsen forklares nedenfor under henvisning til tegningen, hvor fig. 1 viser en container med en påmonteret låseanordning 15 ifølge opfindelsen, fig. 2 en udførelsesform for låseanordningen, set i perspektiv, fig. 3 låseanordningens hus set nedefra, og fig. 4 samme set i snit efter linien IV-IV i fig. 3.The invention is explained below with reference to the drawing, in which fig. 1 shows a container with a mounted locking device 15 according to the invention; FIG. 2 is a perspective view of an embodiment of the locking device; FIG. 3 is a bottom view of the locking device, and FIG. 4 is a sectional view taken along line IV-IV of FIG.

It is equipped with the locking device according to the invention, which as a whole is indicated by 31.

Den i fig. 2 viste låseanordning 31 er fremstillet som en klinke, der består af en arm 1 og en modpart 2. Armen 1 er 25 fastskruet til containeren 30 ved hjælp af fastgørelsesorganer, såsom skruer 3. Skruen 3 har et hovede 22, som passer ind i en forsænkning i armen 1, og den yderste del af hovedet 22 befinder sig i samme plan som den yderste del af armen 1.The FIG. 2 locking device 31 is made as a latch consisting of an arm 1 and a counterpart 2. The arm 1 is screwed to the container 30 by means of fasteners such as screws 3. The screw 3 has a head 22 which fits into a recess in the arm 1, and the outermost part of the head 22 is in the same plane as the outermost part of the arm 1.

Skruen 22 går igennem forskellige former for afstandsstykker 35 og modhold 36 ind i et hul i containeren 30 og spændes med en møtrik 37. I de forskellige former for afstandsstykker 35 og mellem armen 1 og afstandsstykkerne 35 er der indsat bøs-5 ninger 24 og 25. Bøsningerne 24, 25 er forsænkede i afstandsstykkerne 35. Modparten 2 er en integreret del af et af af- » standsstykkerne 35 og kan være udstyret med en hageformet del.The screw 22 goes through various forms of spacers 35 and retainer 36 into a hole in the container 30 and is tightened with a nut 37. In the various forms of spacers 35 and between the arm 1 and the spacers 35, bushings 24 and 25 are inserted. The bushes 24, 25 are recessed in the spacers 35. The counterpart 2 is an integral part of one of the spacers 35 and may be provided with a chin-shaped portion.

Skruen 3 kan i den ende, der er modsat hovedet 22, være udstyret med f.eks. indvendig sekskant eller gevind eller blot et 10 hul, således at det er muligt at fastholde skruen 3 indvendig i containeren 30, når denne skrue 3 skal spændes eller løsnes.The screw 3 may, at the end opposite the head 22, be equipped with e.g. internal hexagon or thread or just a 10 hole, so that it is possible to hold the screw 3 inside the container 30 when this screw 3 is to be tightened or loosened.

På modparten 2 er den ene halvdel af låselegemerne 4 med hul 34 fastgjort. Låselegemet 4 er udformet som et på modparten 2 svejset pladestykke med et boret, gennemgående hul 34. Den 15 anden halvdel af låselegemerne 5 er placeret inde i et hus 7 og er svejset på selve armen 1. Huset 7 er boksformet og har seks sider. Af disse seks sider er siderne 11, 12 og 13 synlige i fig. 1. Den femte side 15 udgøres i det væsentlige af armen 1. Huset 7 er forstærket ved at have ekstra godstykkelse 20 i form af to lag plade i den ende, der er fjernest fra den øverste side 13.On the counterpart 2, one half of the locking members 4 with hole 34 is attached. The locking body 4 is formed as a plate piece welded to the counterpart 2 with a drilled through hole 34. The other 15 half of the locking bodies 5 are located inside a housing 7 and are welded to the arm 1. The housing 7 is box-shaped and has six sides. Of these six pages, pages 11, 12 and 13 are visible in FIG. 1. The fifth side 15 is essentially constituted by the arm 1. The housing 7 is reinforced by having extra thickness 20 in the form of two layers of plate at the end which is farthest from the upper side 13.

I fig. 3 ses huset 7 fra neden. Af husets 7 seks sider ses siden 11, 12, 14 og 15. Den sjette side 16 er egentlig åben. Det er den side, man ser gennem ind i det indre af huset 7. I det .In FIG. 3, the housing 7 is seen from below. Of the six sides of the house 7 are seen pages 11, 12, 14 and 15. The sixth page 16 is actually open. It is the side you see through into the interior of the house 7. In it.

25 indre af huset 7 ses det på modparten 2 fastgjorte låselegeme 4, som skal passe sammen med det andet låselegeme 5, der er fastgjort inde i selve huset 7. Låselegemet 5 er fastgjort til siderne 12, 14 og 15 i huset 7.25, the locking member 4 secured to the counterpart 2 is seen to fit with the second locking member 5 secured within the housing 7. The locking member 5 is secured to the sides 12, 14 and 15 of the housing 7.

I fig. 4 ses huset 7 snittet langs linien IV-IV i fig. 3. IIn FIG. 4, the housing 7 is sectioned along the line IV-IV in FIG. 3. I

h 30 huset 7 er anbragt en hængelås 6 med en retlinet låsepind 8. Låsepindens ene ende er rouletteret. Hverken hængelåsen 6 eller låsepinden 8 er snittet. Huset 7's sider 11, 13, 14 og 16 omkredser hængelåsen 6. Hængelåsen 6 kan låses ved hjælp af en nøgle 33. Låsepinden 8 i hængelåsen er forskydelig og kan for-35 skydes ind igennem hullerne 34 i de to låselegemer 4 og 5. Lå-h 30 housing 7 is provided with a padlock 6 with a rectangular locking pin 8. One end of the locking pin is rotated. Neither the padlock 6 nor the locking pin 8 are cut. The sides 11, 13, 14 and 16 of the housing 7 encircle the padlock 6. The padlock 6 can be locked by means of a key 33. The locking pin 8 in the padlock is slidable and can be slid in through the holes 34 in the two locking members 4 and 5. -

Claims

10 The padlock and thus the locking device are then locked. Due to the difficulty in reaching the central locking parts, the locking device provides increased security against breakage. Due to its location, the locking pin 8 may be made of either hardened or non-hardened material. The latter is advantageous, since when cooled with e.g. carbonic acid cannot cause the locking pin 8 to become brittle so that it can be destroyed by impact. The invention is not limited to the above mentioned embodiments, but can be changed in many ways without thereby departing from its idea. Thus, e.g. the housing may be curved with sides if it is better suited to a given padlock type and the bushings may be of ceramic material. Various parts of the locking device may be made of special materials (eg plastic or ceramic) and the parts may be 25 hardened or insert hardened etc. Patent claims.
