Opfindelsen angår en én- eller tandemakslet anhænger til motorkøretøjer og af den i krav l's indledning angivne art. En anhænger af denne art kendes f.eks. fra patentskrift DE-C-802212.The invention relates to a single or tandem axle trailer for motor vehicles and of the kind specified in the preamble of claim 1. A trailer of this kind is known e.g. from patent specification DE-C-802212.

Især ved anhængere til motorkøretøjer der anvendes til transport af laster, har konstruktionen hidtil været udformet således, at de dertil anvendte plader blev omgivet med et U-formet profil eller blot af et vinkelprofil af metal. Dette 10 profil har i det væsentlige den opgave at overtage beskyttel sen af pladekanterne - det ydede ingen væsentlige bidrag til stivheden af den samlede konstruktion. Af denne grund blev forbindelserne af de enkelte plader indbyrdes, f.eks. hjørneforbindelserne mellem siderne og bagvæg eller hjørneforbin-15 delsen mellem bund- og sidevægge også udført således, at der blev anvendt særlige beslag, som i det væsentlige var forbundet med pladerne, som dannede de egentlige vægge, og kun i få tilfælde havde yderligere forbindelse med de profiler, som omgiver pladerne. Derved fremkom en særlig konstruktion, som 20 stillede særlige fordringer til konstruktionen og montagen og især var forholdsvis omstændelig og tung. Ikke alene blev anhængerens vægt forøget derved med en ugunstig indflydelse på nyttelasten, men omkostningerne til fremstilling og reparationer var væsentligt højere.Especially in the case of motor vehicle trailers used for the transport of loads, the construction has hitherto been designed such that the plates used for this purpose were surrounded with a U-shaped profile or simply with a metal profile. This profile has essentially the task of taking over the protection of the plate edges - it made no significant contribution to the rigidity of the overall construction. For this reason, the connections of the individual plates became mutually exclusive, e.g. the corner connections between the sides and the back wall or the corner connection between the bottom and side walls were also made so that special fittings were used which were essentially connected to the plates which formed the actual walls and only in a few cases had further connection with the the profiles surrounding the panels. This resulted in a special construction which placed special demands on the construction and assembly and in particular was relatively cumbersome and heavy. Not only was the trailer's weight thereby increased with an adverse impact on the payload, but the cost of manufacture and repairs was significantly higher.

Især til plastplader og tilsvarende kendes også en profilstav eller -ramme med en flad midterliste og to vinkelret på hinanden forløbende ben, hvoraf mindst et er krøppet henholdsvis bukket henimod det andet ben på en sådan måde, at afstanden 30 for de indbyrdes parallelt forløbende bendele svarer til tyk kelsen af den plade, der skal fastgøres mellem dem, jf. DE-U-7126992. Denne kendte profilstav eller -ramme danner en kantbeskyttelse for de nævnte plastplader. Den består af letmetal. Profilerne henholdsvis rammerne er især ved hjør-35 nerne forstærket ved særlig indsatte indlæg for dels i det hele taget at opnå en holdbar hjørneforbindelse, men også dels for at give selve rammen den styrke, som profilet med grov behandling skal have især ved hjørnerne for at kunne tåle kraf- 2Particularly for plastic sheets and the like, there is also known a profile rod or frame with a flat center strip and two perpendicularly extending legs, at least one of which is curved or bent towards the other leg in such a way that the distance 30 of the mutually extending leg parts corresponds for the thickness of the plate to be attached between them, cf. DE-U-7126992. This known profile rod or frame provides an edge protection for said plastic sheets. It consists of light metal. The profiles and frames, respectively, are reinforced at the corners by specially inserted inserts to achieve a durable corner joint in general, but also partly to give the frame itself the strength which the rough treatment profile must have, especially at the corners in order to able to withstand force- 2

tige påvirkninger, især ved brug i en anhængerkonstruktion. Profilerne er i hjørneforbindelserne i hvert tilfælde adskilt med et geringssnit. Den sædvanlige hjørneforbindelse sker ved hjælp af særlige hjørneforbindel sesstykker, fortrinsvis af 5 stål, der er indsat i tilsvarende forberedte styr inden for letmetalprofi1 stavene.strong influences, especially when used in a trailer construction. The profiles are in the corner joints in each case separated by a miter cut. The usual corner connection is made by means of special corner connection pieces, preferably of 5 steel, inserted into correspondingly prepared guides within the light metal profile bars.

Det er opfindelsens formål at undgå de nævnte ulemper og også yderligere ulemper ved kendte anhængerkonstruktioner og at 10 tilvejebringe en anhænger til motorkøretøjer, hvis enkeltdele desuden i et vist omfang lader sig standardisere, og som derfor er indbyrdes udskiftelige og også tillader en udformning med forskelligartede konstruktioner med delvis ensartede enkel telementer.It is an object of the invention to avoid the aforementioned disadvantages and also further disadvantages of known trailer structures and to provide a trailer for motor vehicles, the individual parts of which are also, to a certain extent, standardizable and which are therefore interchangeable and also allow a design with different constructions with partially uniform simple telelements.

For at tilgodese dette formål er den indledningsvist omtalte anhænger ifølge opfindelsen ejendommelig ved det i den kendetegnende del af krav 1 anførte.In order to meet this purpose, the trailer according to the invention mentioned above is peculiar to that of the characterizing part of claim 1.

20 Ved den ovenfor beskrevne art af profilets udformning opnås det, at disse profiler har en væsentlig større styrke, og at de af profilerne omgivne plader følgelig kan være væsentlig tyndere, fordi de aflastes væsentligt for kræfter. Sådanne tyndere plader kan også hensigtsmæssigt udformes således, at 25 de er væsentlig mere modstandsdygtige mod andre påvirkninger, som f.eks. fugt, væde, temperaturer o.l. Udformningen af rammeprofilerne frembringer den yderligere fordel, at pladens flader på grund af de udad fremstående rammekanter er væsentligt bedre beskyttet mod mekaniske påvirkninger, især i tra-30 fikken, og at disse rammekanter også kan benyttes til frem bringelse af særlige forbindelser.By the above-described nature of the shape of the profile, it is obtained that these profiles have a considerably greater strength and that the plates surrounded by the profiles can therefore be considerably thinner because they are substantially relieved of forces. Such thinner sheets may also conveniently be designed such that they are substantially more resistant to other stresses such as e.g. moisture, moisture, temperatures and the like. The design of the frame profiles provides the additional advantage that, due to the outwardly projecting frame edges, the surface of the plate is substantially better protected against mechanical stresses, especially in traffic, and that these frame edges can also be used to make special connections.

Desuden er metal prof i 1 rammerne på deres ben forsynet med geringsudsnit og bukket svarende til hjørnerne på den plade, som 35 skal omrammes. Derved opnås der en materialemæssig sammenhæng mellem samtlige rammedele og en tilsvarene bedre kraftoverføring. Ifølge en fordelagtig udformning sluttes rammeprofilet fortrinsvis på en af pladernes langsider i afstand fra hjør- 3In addition, the metal prof in the frames on their legs are provided with miter cut and bent corresponding to the corners of the plate to be 35. This results in a material relationship between all frame parts and a correspondingly better power transmission. According to an advantageous design, the frame profile is preferably joined on one of the long sides of the plates at a distance from the corner.

nerne, og mellem disse ender indsættes et lige profilstykke. Derved kan enderne på den bukede rammedel, som omgiver pladen, ligge på det sted af pladen, hvor den dækkes af halvdelen af et påskruet eller pånittet beslag, og at den anden halvdel af 5 beslaget dækker enderne af det indsatte lige profilstykke.nes, and between these ends an equal profile piece is inserted. Thereby, the ends of the curved frame portion surrounding the plate may lie at the place of the plate where it is covered by half of a screwed-on or cut-out bracket, and the other half of the bracket covers the ends of the inserted straight profile piece.

Ifølge en anden hensigtsmæssig udformning kan rammen bestå af to dele, hvis ender støder op til hinanden ved to indbyrdes overfor hinanden liggende sidekanter på pladen. Rammen kan 10 også bestå af én del og med sine to ender støde op til hinanden et sted ved en af pladens sidekanter.According to another suitable embodiment, the frame may consist of two parts, the ends of which abut each other at two opposite side edges of the plate. The frame 10 may also consist of one part and with its two ends adjacent to one another at one of the side edges of the plate.

Det ses, at rammen på grund af de forskellige, førnævnte beskrevne rammeudformninger består af få eller kun én del, så-15 ledes at ikke blot fremstillingen er væsentligt enklere og mere gunstig, men også at kraftstrømmen er sikret indenfor rammens enkeltstykker.It will be seen that, due to the various aforementioned frame designs, the frame consists of few or only one part, so that not only is the fabrication significantly simpler and more favorable, but also that the power flow is ensured within the frame's individual pieces.

Stødstederne for rammens ender er fortrinsvis udformet og an-20 bragt således, at der dér anbringes beslag, som f.eks. hængsler, lukkekroge eller lignende, som med fastgørelseslasker hver overdækker halvdelen af de to op til hinanden stødende rammeender, og hvis fastgørelsesmidler i form af skruer, nitter o.l. føres igennem de på pladen liggende ben af beslaget.The impact sites at the ends of the frame are preferably formed and arranged so that brackets are provided there, such as e.g. hinges, closure hooks or the like, which with fastening lugs each cover half of the two adjacent frame ends, and whose fasteners in the form of screws, rivets and the like. is passed through the legs of the bracket on the plate.

25 Til rammen er der ved hjælp af skruer eller lignende fastgjort beslag og/eller forbindelsesmidler, der er ført gennem huller, som forløber parallelt med pladeplanet i den del af rammeprofilet, der står ud over pladekanten. Også med denne anbringelse opnås der en væsentlig forbedring af den almindelige 30 stivhed, da de uundgåelige rammesamlinger er forbundet indbyrdes uden yderligere foranstaltninger således, at der til rammesaml i ngerne f.eks. anvendes beslagdele således, at der forefindes en metallisk forbindelse mellem rammesamlingerne.25 The brackets are secured by means of screws or the like through brackets and / or connecting means which are passed through holes which extend parallel to the plate plane in the part of the frame profile which extends beyond the plate edge. Also with this arrangement, a substantial improvement in the ordinary stiffness is achieved, since the inevitable frame assemblies are interconnected without further measures, so that for example frame assemblies, e.g. fittings are used such that there is a metallic connection between the frame assemblies.

35 I pladens randområde er fortrinsvis forbindel sesskruer med deres skruehoveder eller svejsehoveder fast indsat således, at de er dækket af den fra pladekanten fremstående del af rammeprofilet. Til dette kan der i området for de i rammepro-Preferably, in the peripheral region of the plate, connecting screws with their screw heads or welding heads are firmly inserted such that they are covered by the portion of the frame profile projecting from the plate edge. For this, in the area of those in the framework project,

4 filet indsatte skruer, møtrikker eller nitter findes en fordybning, som forskyder profilvæggen indad omtrent med dens tykkelse. Med denne ved hjælp af det særlige rammeprofil ifølge opfindelsen muliggjorte anbringelse af forbindelsesmidler 5 opnås bl.a., at disse forbindelsesmidler er fremragende beskyttet mod enhver uheldig påvirkning. På væsentlige steder danner forbindelsesmidlerne ingen fremspring, som f.eks. kan foranledige uheld.4 fillets, screws, nuts or rivets are provided with a groove which displaces the profile wall inward approximately by its thickness. This, by means of the special frame profile according to the invention, made possible for the application of connecting means 5, it is achieved, inter alia, that these connecting means are excellent protected against any adverse effect. In substantial places, the connecting means do not form protrusions, such as e.g. can cause accidents.

10 Yderkanterne på de to indbyrdes parallelle ben er hensigtsmæssigt bukket indad mod hinanden. Også derved forhindres uheld. Forbindelsen mellem rammeprofilet og pladen forbedres.The outer edges of the two mutually parallel legs are suitably bent inward toward each other. This also prevents accidents. The connection between the frame profile and the plate is improved.

Ifølge opfindelsen ligger et rammeprofil for anhængerplatfor-15 men, hvilket profil i det væsentlige er udformet som et platformens kanter omgribende U-profil,an mod det øverste ben i en bredde svarende til de opstående sidekanters rammeprofil, bag hvilket det er bukket opad og når op over højden af vægramme-profilet og dettes ben, medens det nederste ben rager ud over 20 det øverste bens anlægsflade på platformen. Det opadbukkede ben er forbundet med sidevæggen ved hjælp af skruer eller nitter, som går gennem disse ben samt de to ben i sidevægsindramningen og den derimellem liggende plade. Med denne anbringelse opnås en væsentlig forøgelse af styrken af forbindel-25 serne mellem platformen eller kassebunden med sidevæggene, da platformens rammeprofi 1 dele ligger parallelt med og umiddelbart støder op til profildelene for sidevæggenes rammer, således at forbindelsen ved hjælp af forbindelsesmidler frembringer en delvis formtilpasset forbindelse. Resultatet er en 30 forøgelse af stivheden og styrken samt en gensidig beskyttelse mod uheldige påvirkninger fra vejrliget.According to the invention, a frame profile of the trailer platform, which profile is essentially formed as a platform's circumferential U-profile, abuts the upper leg in a width corresponding to the frame profile of the raised side edges, behind which it is bent upwards and reaches up above the height of the wall frame profile and its legs, while the lower leg protrudes beyond the abutment surface of the upper leg on the platform. The upwardly bent leg is connected to the sidewall by means of screws or rivets passing through these legs as well as the two legs of the sidewall framing and the plate lying therebetween. With this arrangement, a substantial increase in the strength of the connections between the platform or the box bottom is achieved with the sidewalls, since the frame profile of the platform 1 is parallel to and immediately adjacent to the profile parts of the sidewall frames, so that the connection produces a partially shaped fit. connection. The result is a 30 increase in stiffness and strength as well as a mutual protection against adverse effects from the weather.

En køretøjsanhænger ifølge opfindelsen består af kørestellet med hjulene 1 samt en platform eller bundplade 2, sidevæggene 25 3 og forvæggen 4 samt bagvæggen 5. De enkelte vægge består af træ, træmateriale eller af et andet materiale, og er på alle sider omgivet af metalprofiler.A vehicle trailer according to the invention consists of the driving frame with the wheels 1 as well as a platform or base plate 2, the side walls 25 3 and the front wall 4 and the rear wall 5. The individual walls are made of wood, wood material or other material and are surrounded on all sides by metal profiles.

Metal rammerne, som omgiver pladen 6, har som vist i fig. 4 og 30 5 to indbyrdes parallelle ben, nemlig et indre ben 7 og et ydere ben 8. Fra det indre ben 7 er rammeprofilet bukket eller bøjet om vægpladens kant 9 og danner en midterdel 10, som på den ene side af denne kant 9 rager ind over pladen 6. Midterdelen 10 og benet 7 har fortrinsvis samme længde. Den del af 35 midterdelen 10, der rager ud over pladen 6's tykkelse, er mindst lige så lang som den halve pladetykkelse. Ifølge udførelseseksemplet i fig. 4 kan en skråforbindelse 12 til benet 8 i profilet frembringes af den yderste ende af midterdelen 10 med en dobbeltbukm'ng 11. Mellem benet 8 og den skrå del 12 findes så en stump vinkel, medens der mellem midterdelen 10 og dens skrå del 12 findes en spids vinkel.The metal frames surrounding the plate 6 have as shown in FIG. 4 and 30 5 are two parallel legs, namely an inner leg 7 and an outer leg 8. From the inner leg 7, the frame profile is bent or bent around the edge of the wall plate 9 and forms a central part 10 which protrudes on one side of this edge 9 preferably over the plate 6. The center portion 10 and the leg 7 preferably have the same length. The portion of the middle portion 10 extending beyond the thickness of the plate 6 is at least as long as the half plate thickness. According to the embodiment of FIG. 4, an inclined connection 12 to the leg 8 of the profile can be provided by the outer end of the middle part 10 with a double bend 11. Between the leg 8 and the inclined part 12 a blunt angle is then found, while between the middle part 10 and its inclined part 12 and a pointed angle.

s 5 Ifølge det andet udførelseseksempel i fig. 5 er der fra midterdelen i den ende, som rager ud, først foretaget en retvinklet bøjning 13, og fra denne fører en yderligere retvinklet bøjning 14 til benet i rammeprofi 1 et.s 5 According to the second embodiment of FIG. 5, a right-angled bend 13 is first made from the middle portion at the projecting end, and from this a further right-angled bend 14 leads to the leg in frame profile 1.

10 på fig. 2 og 3 vises forskelige udformninger af den samlede anbringelse af rammen. Ifølge figuren består rammen, som omgiver en sidevæg 3, 4 eller 5, af to dele 15 og 16, som er spejlsymmetriske og er skudt ind fra oven eller fra neden over pladen. Til forbindelse er der anbragt huller 17, af hvilke to 15 ligger i de to op til hinanden stødende ender 18 af rammedelen. Et yderligere hul 17 kan også ligge i pladen 6. Disse huller, som tjener til forbindelse af de to rammedele, tjener samtidigt også til anbringelse af beslag, i det her foreliggende tilfælde f.eks. til anbringelse af et lukkebeslag, i det 20 tilfælde, hvor det drejer sig om en bagvæg 5.10 in FIG. 2 and 3, different designs of the overall arrangement of the frame are shown. According to the figure, the frame, which surrounds a side wall 3, 4 or 5, consists of two parts 15 and 16 which are mirror-symmetrical and projected in from above or from below the plate. For connection, holes 17 are provided, two of which 15 lie at the two adjacent ends 18 of the frame portion. An additional hole 17 may also lie in the plate 6. These holes, which serve to connect the two frame parts, also simultaneously serve for mounting brackets, in the present case e.g. for mounting a closure bracket, in the case of a rear wall 5.

Som vist i fig. 3 er hele rammen, som omslutter pladen 6, udformet gennemgående som ét stykke, og i hjørnerne er der indksåret geringer, således at de dele af profilet, som danner 25 de ydre rammekanter, skal bukkes. Der forefindes kun et enkelt stødsted 19, som også i dette tilfælde har huller 17 til et beslag, som hensigtsmæssigt skal anbringes på dette sted, f.eks. beslaget til forbindelse med trækstangen, når det drejer sig om en forvæg 4. Et ikke her vist udførelseseksempel er 30 anvendeligt ved en sidevæg 3. Ifølge dette er den omsluttende profil ramme til sidevæggen 3 udformet således, at den ligesom på fig. 3 omgiver samtlige sidekanter, men hvor der på den underste sidekant mellem støddene 19 friholdes en større afstand. Her indsættes en særlig prof i 1 rammedel, og ved de i 35 dette tilfælde dobbelte stød befinder der sig anbringelsespunkter for fastgørelsesmidler til beskyttelsespladen 26, som omgiver den øvre del af hjulet 1.As shown in FIG. 3, the entire frame enclosing the plate 6 is integrally formed as one piece, and in the corners there are inserts wound so that the parts of the profile forming the outer frame edges must be bent. There is only a single impact site 19, which also in this case has holes 17 for a fitting which should be conveniently placed at that location, e.g. the bracket for connection to the drawbar in the case of a front wall 4. An exemplary embodiment not shown here is applicable to a sidewall 3. According to this, the enclosing profile frame for the sidewall 3 is designed so that, as in FIG. 3 surrounds all the side edges, but where a greater distance is maintained on the lower side edge between the supports 19. Here, a special prof is inserted into 1 frame member, and in the case of double bumps in this case, there are mounting points for fasteners to the protective plate 26 which surrounds the upper part of the wheel 1.

7 I fig. 6 vises hjørneforbindelsen mellem to sidevægge. Eksempelvis er sidevæggen 3 forbundet med endevæggen 4. Midterdelen 10 af sidevæggen 3's rammeprofil er lagt an mod det omtrent lige så lange ben 7 af endevæggen 4's rammeprofil. I området 5 for enden af den plade 6, som danner sidevæggen, har de to mod hinanden liggende dele et gennemgående hul. Flugtende med dette gennemgående hul har endevæggen 4's plade 6 et gennemgående hul, hvilket også gælder for benet 8 på endevæggens yderside. Allerede ved sidevæggens 3 fremstilling før rammens 10 påsætning, kan der i en udsparing i pladen 6, der svarer til rammehullet, indsættes en skrue med sit hoved således, at den med sit skaft rager ud af sidevæggens ramme. Denne skrues skaft føres gennem sidevæggens gennemgående huller og på ydersiden påskrues en møtrik. Det kan også indenfor rammens mid-15 terdel 10 på sidevæggen anbringes en svejsemøtrik på hullet i rammens midterdel 10, således at der udefra gennem det forberedte hul i sidevæggen 4 kan indskrues en skrue i denne svejsemøtrik. I hvert tilfælde er den ene del af denne skrueforbindelse usynlig og beskyttet mod beskadigelser. Forbindel-20 sens blotliggende del ligger under den fremspringende del af sidevæggen 4's ramme. Denne fremspr ingende del består af forlængelsen af midterdelen 10 samt de bukkede dele 13 og 14.7 In FIG. 6 shows the corner connection between two side walls. For example, the side wall 3 is connected to the end wall 4. The middle part 10 of the frame profile of the side wall 3 is aligned with the approximately equal leg 7 of the frame profile of the end wall 4. In the region 5 at the end of the plate 6 which forms the side wall, the two opposite parts have a through hole. Flush with this through hole, plate 6 of end wall 4 has a through hole, which also applies to the leg 8 on the outside of the end wall. Already in the manufacture of the side wall 3 before the installation of the frame 10, in a recess in the plate 6 corresponding to the frame hole, a screw with its head can be inserted so that with its shaft it protrudes from the frame of the side wall. The shaft of this screw is passed through the through holes of the sidewall and the nut is screwed to the outside. It is also possible to place a welding nut within the middle part 10 of the frame 10 on the side wall, in the hole in the middle part 10 of the frame, so that a screw can be screwed in from this outside through the prepared hole in the side wall 4. In each case, one part of this screw joint is invisible and protected from damage. The exposed portion of the connector 20 lies below the projecting portion of the frame of the sidewall 4. This protruding part consists of the extension of the middle part 10 as well as the bent parts 13 and 14.

Ved anvendelsen af en svejsemøtrik inde i sidevæggen 3's ramme 25 kan denne også anbringes som vist i fig. 8 og 9. I området for svejsemøtrikken er rammens midterdel· 10 på profilvæggen forskudt omtrent denne vægs tykkelse indad, således at der f.eks. mellem de to på hinanden liggende rammedele er yderligere plads til anbringelsen af en mellemlægsskive, som kan bestå af 30 et elastisk materiale. Svejsemøtrikken 19 er fortrinsvis anbragt i området for den indsatte plade 6's kant 9, og til dette formål har pladen på dette sted en udsparing. Svejsemøtrikken 19 kan imidlertid også påsættes i området for rammeprofilets "udadrettede hvælving" indefra på det forlængede 35 midterstykke 10 overfor profildelen 14, hvilket betinger, at sidevæggen 3 i forbindelsen er rykket længere indad, og at profilets "hvælving" i sidevæggen 3's profil flugter med hullet i de to ben 7 og 8 i endevæggen 4's rammeprofil.When using a welding nut within the frame 25 of the sidewall 3, it can also be applied as shown in FIG. 8 and 9. In the area of the welding nut, the middle portion · 10 of the frame on the profile wall is displaced approximately the thickness of this wall inwards, so that e.g. between the two adjacent frame parts is further space for the placement of a spacer which may consist of an elastic material. The welding nut 19 is preferably arranged in the region of the edge 9 of the inserted plate 6, and for this purpose the plate at this location has a recess. However, the welding nut 19 may also be applied in the region of the "outwardly curved" frame of the frame on the elongated center piece 10 opposite the profile portion 14, which means that the side wall 3 of the connection is extended further inwardly and that the "vault" of the profile in the side wall 3 flushes with the hole in the two legs 7 and 8 in the frame profile of the end wall 4.

DK 155426 BDK 155426 B

a "Hvælvingen" rager også ud over fastgørelsesmidlerne henholdsvis disses hoveder for rammen på selve sidevæggen. Disse fastgørelser foretages i almindelighed med nitter, hvor hovederne er udformet fladt linseformet, således at der ikke derved 5 findes væsentlige fremspring ud over sidevægsplanet eller indad til. Ved en rammeudformning ifølge opfindelsen er der dog mulighed for, at undgå de med en sådan nittefastgørelse af prof i 1 rammerne forbundne ulemper, der kan endda også til fastgørelse af rammen på pladen anvendes skruer, som med flade 10 linsehoveder ligger an mod de lange ben 8, medens de på den over for liggende side med det korte ben 8, f.eks. er sikret med møtrikker med hovede. At disse møtrikker med hovede står længere frem spiller ingen rolle, da de der er beskyttet og dækket af "hvælvingerne" i rammeprofilet. Det samme gør sig 15 gældende ved fastgørelsen af samtlige beslag, såsom hængslerne 20 til bagklappen og fastgørelserne og låse i ndretni ngerne 21 ligeledes til bagklappen.a "The vault" also extends beyond the fasteners and their heads, respectively, to the frame of the side wall itself. These fasteners are generally made with rivets where the heads are formed flat lens-shaped, so that no substantial projections are found beyond the sidewall plane or inwards. However, in a frame design according to the invention, it is possible to avoid the disadvantages associated with such a rivet attachment of the prof in the frames, which can even be used for fastening the frame to the plate screws which with flat 10 lens heads abut the long legs 8, while on the opposite side of the short leg 8, e.g. is secured with head nuts. The fact that these nut heads are further forward does not matter, as the ones protected and covered by the "vaults" in the frame profile. The same applies to the attachment of all the fittings, such as the hinges 20 to the tailgate and the fasteners and locks in the restraints 21 also to the tailgate.

Udformningen af bundplatformen og forbindelsen af væggene med 20 platformen er gennemført på følgende måde:The design of the bottom platform and the connection of the walls to the platform are carried out as follows:

Ved det underste ben 22 er der ved hjælp af en bukning frembragt en midterdel 23, som dækker bundpladens eller platformens kant, hvorfra atter det øvre ben 24 er bukket indad. Der-25 til slutter der sig en opstående bukning 25, hvis længde omtrent svarer til længden af den lange flange 7 af sidevæggenes rammeprofil. På fig. 7 ses, hvorledes forbindelsen er frembragt. Her ses også, at det øvre ben 24’s længde omtrent svarer til længden af sidevægprofilets midterstykke 10 således, 30 at midterdelen 10 og den lange flange 7 ved indsætning af sidevæggene forløber parallelt med bundprofilets ben 24 og opretstående del 25, hvorhos sidstnævnte på overkanten har en udadrettet bukning, som griber ind over den tilsvarende bukning på det lange ben af sidevæggenes rammeprofil. Ved monte-35 ring af sidevæggene i bundprofilet opnås altså et delvis formsluttende anlæg. Forbindelsen sker ved hjælp af skruer eller svejsemøtrikker 29, som det i forbindelse med fig. 6 er beskrevet ovenfor i forbindelse med samlingen af sidevæggeneAt the lower leg 22, by means of a bend, a central part 23 is formed which covers the edge of the base plate or platform, from which again the upper leg 24 is bent inwards. There is then a rising bend 25, the length of which corresponds approximately to the length of the long flange 7 of the frame profile of the sidewalls. In FIG. 7 shows how the compound is produced. It is also seen here that the length of the upper leg 24 corresponds approximately to the length of the center piece 10 of the sidewall profile such that the middle portion 10 and the long flange 7, when inserting the sidewalls, extend parallel to the base 24's legs 24 and upright portion 25, the latter having an upper edge. outward bending, which engages the corresponding bend on the long leg of the frame profile of the sidewalls. Thus, by installing the side walls in the bottom profile, a partially molded system is obtained. The connection is made by means of screws or welding nuts 29, as in connection with FIG. 6 is described above in connection with the assembly of the side walls
