Den foreliggende opfindelse angår et samlearrangement omfattende en låsestift, et sam-lebeslag med mindst to ilanger, der er forbundet via en central del, samt en not i sidekanten på en møbelplade, fortrinsvis til dannelse af et reolsystem, hver af hvilke flanger er indrettet for indgreb i noten, hvorhos mindst en låsestift strækker sig gennem linie-5 stillede boringer på hver side af noten i møbelpladen samt gennem en i flangen tilvejebragt boring, som er liniestillet med møbelpladeboringeme, når flangen er optaget i noten.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collector assembly comprising a locking pin, an assembly bracket having at least two central joints connected via a central portion, and a groove in the side edge of a furniture plate, preferably to form a shelving system, each of which has flanges arranged engaging the groove, wherein at least one locking pin extends through aligned bores on each side of the groove in the furniture plate and through a bore provided in the flange which is aligned with the furniture plate bores when the flange is accommodated in the groove.

Der kendes beslag af denne type. Et eksempel på et sådant kendt arrangement er beskre-10 vet i fransk patent nr. 2.406.405.1 dette skrift beskrives et samlebeslag, der omfatter to indbyrdes forbundne flanger, der er beregnet til at samvirke med spor i sidekanten på møbelplader. Samlebeslagets flanger fastgøres i sporene ved hjælp af en låsestift, der strækker sig gennem en i møbelpladen dannet boring, der kan liniestilles med en boring i flangen, når denne er optaget i møbelpladens spor.Fittings of this type are known. An example of such a known arrangement is described in French Patent No. 2,406,405. This specification discloses an assembly bracket comprising two interconnected flanges intended to cooperate with grooves in the side edge of furniture panels. The flange of the assembly bracket is secured to the grooves by means of a locking pin extending through a bore formed in the furniture plate which can be aligned with a bore in the flange when it is received in the groove of the furniture plate.

Det beskrevne samlearrangement er ufordelagtigt, idet samlebeslaget skal positioneres meget nøjagtigt og skal være fuldt indskudt i noten, inden det er muligt at isætte låsestiften. Den usikre positionering af flangen i møbelpladens not giver risiko for, at flangens boring er forskudt i forhold til boringerne i møbelpladen.The described assembly arrangement is disadvantageous in that the assembly bracket must be positioned very accurately and must be fully inserted into the groove before it is possible to insert the locking pin. The uncertain positioning of the flange in the groove of the furniture plate presents a risk that the bore of the flange is displaced relative to the bores in the furniture plate.

Endvidere er samlebeslaget fremstillet af to eller flere flanger med samme tværdimension over hele flangens udstrækning. Dette betyder, at det møbel, som er dannet, vil være afhængig af et direkte anlæg mellem møbelpladens sidekanter. Dette er ufordelagtigt i forbindelse med møbelplader, der ofte er fremstillet af træ, hvor dimensionerne vil af-25 hænge af fugtighed og varme. Såfremt møbelpladen arbejder, vil der være risiko for, at låsestiften falder ud, idet indgrebet mellem låsestift og flange alene er etableret via den friktion, der eksisterer mellem låsestiften og boringerne i flange samt møbelplade. Dette stiller meget høje krav til tolerancer såvel for låsestift som for møbelplade. En sådan konstruktion vil nærmest være umulig at adskille, når den en gang er samlet, idet en 30 låsestift ikke vil kunne udtages fra en boring i møbelpladen, hvor den vil sidde i en prespasning.Furthermore, the connecting bracket is made of two or more flanges with the same cross-dimension over the entire flange extent. This means that the furniture that is formed will depend on a direct abutment between the side edges of the furniture plate. This is disadvantageous in connection with furniture panels often made of wood, the dimensions of which will depend on humidity and heat. If the furniture plate is working, there will be a risk of the locking pin falling out, since the engagement between the locking pin and the flange is established solely via the friction that exists between the locking pin and the holes in the flange as well as the furniture plate. This places very high demands on tolerances for both the locking pin and the furniture plate. Such a construction will be almost impossible to disassemble once assembled, as a locking pin will not be able to be removed from a bore in the furniture plate where it will fit in a press fit.

DK 171838 B1 2DK 171838 B1 2

Det franske system er endvidere ufordelagtigt, idet låsestiften er placeret helt inde i et hjømeområde ved samling mellem to møbelplader. Dette vil vanskeliggøre brugen af værktøj til rotation af låsestiften for et fast indgreb med samlebeslagets flange.Furthermore, the French system is disadvantageous in that the locking pin is located completely inside a corner area when assembled between two pieces of furniture. This will make it difficult to use the tool to rotate the locking pin for a fixed engagement with the flange of the connector.

S Det er formålet med den foreliggende opfindelse at anvise et samlebeslag af den ovenfor nævnte type, som afhjælper disse ulemper.It is the object of the present invention to provide an assembly bracket of the above-mentioned type which addresses these disadvantages.

Dette opnås ifølge den foreliggende opfindelse med et samlearrangement, der er særpræget ved, at flangeboringeme og møbelpladeboringeme har stort set samme diameter, 10 at hver flangeboring er forbundet med et indgangsspor, der udmunder ved flangens sidekant, og som har en mindre bredde end boringens diameter, at låsestiften er et stort set cylindrisk legeme med en diameter svarende til flangeboringens diameter og med et par diametralt modstillede spor i cylinderfladen, hvilke spor er dannet med en indbyrdes afstand, der stort set svarer til bredden af indgangssporet, og at den centrale del omfatter 1S mindst et fremspring til indgreb med møbelpladens sidekant.This is achieved in accordance with the present invention with a collector arrangement, characterized in that the flange bores and furniture plate bores have substantially the same diameter, that each flange bore is connected to an entrance groove which opens at the side edge of the flange and which has a smaller width than the diameter of the bore. the locking pin being a substantially cylindrical body having a diameter corresponding to the diameter of the flange bore and having a pair of diametrically opposed grooves in the cylinder surface, which grooves are spaced substantially equal to the width of the input groove and the central portion comprises 1S at least one projection for engagement with the side edge of the furniture plate.

Samlearrangementet gør det muligt at montere låsestiften i møbelpladen og benytte låsestiften som et styrende element ved indføringen af flangen og til at trække samlebe-slaget i tæt anlæg mod møbelpladen.The collector arrangement makes it possible to mount the locking pin in the furniture plate and to use the locking pin as a guiding element when inserting the flange and to pull the connector in close contact with the furniture plate.

Idet indgangssporet til flangeboringen udmunder i flangens sidekant, vil det, ved samling af flere møbelplader ved hjælp af samlearrangementet ifølge den foreliggende opfindelse, være muligt at placere låsestiften i møbelpladeboringeme, inden flangen isæt tes. Låsestiften indsættes, således at de to spor i cylinderfladen står vinkelret på møbel-25 pladens sidekant. Dette kan ses ved en indsætning af låsestifteme og kan alternativt indikeres ved et kærvspor i en endeflade på låsestiften, som er orienteret parallelt med hvert af sporene. Det vil herefter være muligt at indsætte samlebeslagets flange i noten. En sådan indføring sker let, idet hver indgangsspor vil samvirke med en låsestift, som styrer samlebeslaget ind i en korrekt positionering i noten. Flangen føres ned i bunden af 30 noten, idet hvert indgangsspor er placeret ud for flangen. Dette kan hensigtsmæssigt ske ved, at møbelpladeboringen på den ene side af noten er et bundhul, der er dimensione- 3 DK 171838 B1 ret, således at sporene vil befinde sig ud for noten, når låsestiften er presset helt ned i bundhullet.As the entrance groove for the flange bore opens into the side edge of the flange, it will be possible, by assembling several furniture plates by means of the collector arrangement according to the present invention, to place the locking pin in the furniture plate bores before the flange is inserted. The locking pin is inserted so that the two grooves in the cylinder surface are perpendicular to the side edge of the furniture plate. This can be seen by inserting the locking pins and may alternatively be indicated by a notch groove in an end surface of the locking pin which is oriented parallel to each of the grooves. It will then be possible to insert the flange of the fittings into the groove. Such insertion is easy, since each input groove will cooperate with a locking pin, which guides the assembly bracket into proper positioning in the groove. The flange is passed down to the bottom of the groove, with each input groove positioned next to the flange. This may conveniently be accomplished by the fact that the furniture plate bore on one side of the groove is a bottom hole that is dimensionally straight so that the grooves will be off the groove when the locking pin is pressed fully into the bottom hole.

Når flangen er presset i bund i noten, vil låsestiften befinde sig i flangeboringen. I denne 5 position roteres låsestiften. Rotationen sker fortrinsvis gennem en vinkel på 90°. Ved at danne et fremspring i flangeboringen kan der dannes et stopanslag, der samvirker med bunden af et spor i låsestiften. Herved kan det sikres, at rotation kun sker gennem 90°. Herved stilles låsestiftens spor på tværs af indgangssporet. Da låsestiftens cylindriske legeme har en diameter, der er større end bredden af indgangssporet, vil flangen nu være 10 fastlåst i noten i korrekt position. En korrekt positionering er endvidere sikret ved, at den centrale dels fremspring er i indgreb med møbelpladens sidekant. Ved samling af flere møbelplader vil et direkte anlæg mellem møbelplademes sidekant ikke være nødvendig. Møbelplademes indbyrdes positionering sker gennem sidekantemes indgreb med hvert sit fremspring på samlebeslagets centrale del.When the flange is pressed into the bottom of the groove, the locking pin will be in the flange bore. In this position, the locking pin is rotated. The rotation is preferably through an angle of 90 °. By forming a projection in the flange bore, a stop stop can be formed which cooperates with the bottom of a groove in the locking pin. In this way it can be ensured that rotation occurs only through 90 °. This places the locking pin groove across the input groove. Since the cylindrical body of the locking pin has a diameter greater than the width of the input groove, the flange will now be locked in the groove in the correct position. Furthermore, proper positioning is ensured by the projections of the central part engaging with the side edge of the furniture plate. When assembling multiple pieces of furniture, a direct installation between the sides of the furniture panels will not be necessary. The mutual positioning of the furniture plates takes place through the engagement of the side edges with each projecting on the central part of the fittings.

Det vil være muligt blot at anvende en låsestift, men det foretrækkes at anvende to eller flere i et samlebeslag ifølge opfindelsen. Det foretrækkes endvidere, at møbelpladen har affasede hjørner, som efterlader en plan anlægskant på hver side af noten. Det bliver herved muligt at placere møbelplademes sidekant meget nær hinanden. I en særlig fore-20 trukket udførelsesform vil aflåsningen af hjørnerne have en sådan størrelse, at den anlægskant, der efterlades på hver side af noten, har en bredde, som svarer til bredden af fremspringet på samlebeslagets centrale del. I denne situation vil der i en hjømesamling opstå et anlæg mellem møbelplademes sidekant og fremspringene på den centrale del samt et anlæg mellem de affasede dele af sidekanteme. Herved opnås en særlig stiv og 25 sikker samling.It will be possible to use only a locking pin, but it is preferable to use two or more in an assembly bracket according to the invention. It is further preferred that the furniture plate has bevelled corners which leave a flat abutment on each side of the groove. This makes it possible to place the side edges of the furniture panels very close together. In a particularly preferred embodiment, the locking of the corners will be such that the abutment edge left on each side of the groove has a width corresponding to the width of the projection on the central portion of the assembly bracket. In this situation, in a home assembly, a system will occur between the side edge of the furniture panels and the projections on the central portion as well as a plant between the bevelled portions of the side edges. This results in a particularly rigid and secure assembly.

Ifølge en yderligere foretrukket udførelsesform foretrækkes det, at flangeboringen er anbragt i umiddelbar nærhed af en flanges sidekant. Herved vil låsestiften være placeret så langt fra møbelpladens sidekant som muligt. Dette vil lette brugen af værktøj ved 30 anvendelse af samlearrangementet ifølge opfindelsen. Det foretrækkes således, at flangeboringen tilnærmelsesvis kan tangere flangens sidekant, det vil sige, at indgangssporet har så kort udstrækning som muligt.According to a further preferred embodiment, it is preferred that the flange bore is disposed in the immediate vicinity of the side edge of a flange. In this way, the locking pin will be positioned as far from the side edge of the furniture plate as possible. This will facilitate the use of tools in using the collector arrangement of the invention. It is preferred that the flange bore may approximate the lateral edge of the flange, that is, the input groove has as short a range as possible.

Det foretrækkes at placere indgangssporet asymmetrisk i forhold til ilangeboringen. Herved kan flangens fremspring trækkes i anlæg mod møbelpladens sidekant ved en rotation af låsestiften, idet der optræder en vægtstangsvirkning mellem flangeboringen og låsestiftens centrale del mellem de to spor. Endvidere bliver det muligt at have et 5 indgangsspor, der er meget kort, og hvor det stadig vil være muligt at have en fastholdelse af låsestiften i flangeboringen med en relativ lille materialetykkelse, der befinder sig ved siden af indgangssporet. Længden af indgangssporet og dermed styrken af det materiale, der fastholder låsestiften, afhænger af materialevalg for samlebeslaget. Det foretrækkes at anvende aluminium til samlebeslaget, men det vil også være muligt at 10 anvende andre materialer, som for eksempel stål eller plastmaterialer. Låsestiften vil fortrinsvis være fremstillet af et plastmateriale. Såfremt låsestiften er fremstillet af et plastmateriale, er en mindre deformation af låsestiften mulig ved låsestiftens rotation i flangeboringen. Herved kan der kompenseres for små toleranceforskelle i samlingen.It is preferred to position the input groove asymmetrically with respect to the longitudinal bore. Hereby the protrusion of the flange can be pulled into contact with the side edge of the furniture plate by a rotation of the locking pin, there being a lever action between the flange bore and the central part of the locking pin between the two grooves. Furthermore, it will be possible to have a very short entry groove and where it will still be possible to have a locking pin in the flange bore with a relatively small material thickness adjacent to the input groove. The length of the input groove and thus the strength of the material holding the locking pin depends on the material selection for the fittings. It is preferred to use aluminum for the fittings, but it will also be possible to use other materials, such as steel or plastic materials. The locking pin will preferably be made of a plastic material. If the locking pin is made of a plastic material, a minor deformation of the locking pin is possible by the rotation of the locking pin in the flange bore. This allows for small tolerance differences in the assembly to be compensated.

15 Det er også muligt at kompensere for toleranceforskelle i møbelplademe ved at fremstille låsestiften med et ringformet fremspring med større yderdiameter end diameteren for det cylindriske legeme ved hver ende af dette. En sådan låsestift vil samvirke med mø-belpladeboringer, som har en diameter, der stort set svarer til yderdiameteren på fremspringene. Ved rotation af en sådan låsestift vil fremspringene delvis kunne trænge ind i 20 møbelpladen og kompensere for mindre toleranceforskelle. Det bemærkes her, at låsestiftens positionering primært vil være bestemt af flangeboringen, idet flangeboringens diameter stort set svarer til diameteren for det cylindriske legeme. Da de ringformede fremspring kan trænge ind i træet, vil et sådant samlearrangement tillade at træet arbejder som følge af fugtpåvirkninger.It is also possible to compensate for tolerance differences in the furniture panels by producing the locking pin with an annular projection with a larger outer diameter than the diameter of the cylindrical body at each end thereof. Such a locking pin will cooperate with furniture plate bores having a diameter substantially equal to the outer diameter of the projections. By rotating such a locking pin, the projections may partially penetrate the furniture plate and compensate for minor tolerance differences. It is noted here that the positioning of the locking pin will be determined primarily by the flange bore, the diameter of the flange bore being roughly equal to the diameter of the cylindrical body. Since the annular projections can penetrate the tree, such a gathering arrangement will allow the tree to work due to moisture influences.

Ifølge en yderligere udførelsesform vil bundfladerne i låsestiftens spor, der over størstedelen af deres længde forløber i parallelle plan, have et kurveformet forløb i retning mod det modstående spor. Dette vil sammen med afrundede hjørner ved indgangssporet være medvirkende til at lette en positionering af flange og efterfølgende indføring af 30 flangen i noten, hvorved låsestifteme føres ind i indgangssporet og igennem dette.According to a further embodiment, the bottom surfaces of the locking pin groove, which extend over most of their length in parallel plane, will have a curved course towards the opposite groove. This, together with rounded corners at the entrance groove, will assist in facilitating the positioning of the flange and subsequent insertion of the flange into the groove, whereby the locking pins are inserted into and through the entrance groove.

Det foretrækkes, at møbelpladens not har en længde, der er kortere end sidekanten, og at flangen har en størrelse og form, således at den optages i denne not. Herved vil flangen ikke være synlig fra forsiden af et møbel, for eksempel en reol, der er dannet ved anvendelse af et samlebeslag ifølge opfindelsen. Imidlertid kan samlebeslagets centrale del S have en længere udstrækning, således at dette kan strække sig til forsiden af et møbel, som er fremstillet af sådanne møbelplader.It is preferred that the groove of the furniture plate has a length shorter than the side edge and that the flange has a size and shape so that it is accommodated in this groove. Hereby, the flange will not be visible from the front of a piece of furniture, for example a shelf formed using an assembly bracket according to the invention. However, the central part S of the fittings may have a longer extension, so that this may extend to the front of a piece of furniture made of such piece of furniture.

Opfindelsen vil herefter blive forklaret nærmere under henvisning til den medfølgende tegning, hvor 10 fig. 1 viser et partielt snit gennem møbelplader, der er indbyrdes forbundne ved hjælp af forskellige udførelsesformer for et samlearrangement ifølge opfindelsen, fig. 2 viser et sidebillede til illustration af et samlebeslag, der indgår i et samle- 15 arrangement ifølge opfindelsen, fig. 3 og 4 viser to partielle sidebilleder af en møbelplade med en not, der indgår i et samlearrangement ifølge opfindelsen, fig. 5 viser et partielt billede af et samlebeslag og en låsestift, der indgår i et samlearrangement ifølge opfindelsen, 20 fig. 6 og 7 viser to sidebilleder af en låsestift, fig. 8 viser et endebillede af den i fig. 6 og 7 viste låsestift, og fig. 9 og 10 viser to sidebilleder svarende til fig. 6 og 7 til illustration af en yderligere udførelsesform for en låsestift.The invention will now be explained in more detail with reference to the accompanying drawing, in which: FIG. 1 is a partial sectional view of furniture plates interconnected by various embodiments of a collector arrangement according to the invention; FIG.

25 I tegningens forskelle figurer vil samme henvisningsbetegnelser benyttes til at betegne identiske eller tilsvarende elementer. Opfindelsen vil i det efterfølgende blive forklaret under en samtidig henvisning til tegningens forskellige figurer.In the various figures of the drawing, the same reference numerals will be used to denote identical or similar elements. The invention will be explained in the following with a simultaneous reference to the various figures of the drawing.

Samlearrangementet omfatter en låsestift 1, et samlebeslag 2,3,4, der har mindst to flan-30 ger 5, som er forbundet via en central del 6. Samlearrangementet omfatter endvidere en not 7, som er tilvejebragt i sidekanten 8 på en møbelplade 9. Samlearrangementet er fortrinsvis beregnet til dannelse af et reolsystem. Imidlertid kan samlebeslaget også an- DK 171838 B1 6 vendes til fremstilling af andre møbler, som for eksempel stole, skabe eller lignende. Hver flange 5 er indrettet for indgreb i noten 7, hvorved låsestiften 1 kan passere gennem liniestillede møbelpladeboringer 10,11 på hver side af noten 7 samt gennem en boring 12, der er tilvejebragt i flangen 5. Flangeboringen 12 er liniestillet med møbel-5 pladeboringeme 10,11, når flangen S er optaget i noten 7.The collector assembly comprises a locking pin 1, an assembly bracket 2,3,4 having at least two flanges 5 connected via a central portion 6. The collector assembly further comprises a groove 7 provided in the side edge 8 of a furniture plate 9 The collector assembly is preferably intended to form a shelving system. However, the fittings can also be used to make other furniture, such as chairs, cabinets or the like. Each flange 5 is arranged for engagement with the groove 7, whereby the locking pin 1 can pass through aligned furniture plate bores 10,11 on each side of the groove 7 and through a bore 12 provided in the flange 5. The flange bore 12 is aligned with the furniture-5 plate bores 10.11 when the flange S is included in the groove 7.

I fig. 1 illustreres forskellige typer samlebeslag. Samlebeslaget 2 benyttes til en hjørne-samling. Samlebeslaget 3 benyttes til en T-samling, og samlebeslaget 4 benyttes til en krydssamling.In FIG. 1 illustrates different types of assembly fittings. The bracket 2 is used for a corner assembly. The fittings 3 are used for a T-joint and the fittings 4 are used for a cross-joint.

10 I fig. 1 ses, at sidekanten 8 af hver møbelplade er forsynet med affasninger 13. Aflåsningerne 13 efterlader en plan sidekant 14 på hver side af sporet 7. Den plane sidekant 14 er beregnet til at samvirke med en anlægsflade 15 på et fremspring 16 af samlebesla-gets centrale del 6.10 In FIG. 1 it is seen that the side edge 8 of each furniture plate is provided with bevels 13. The locks 13 leave a flat side edge 14 on each side of the groove 7. The flat side edge 14 is intended to cooperate with a abutment surface 15 on a projection 16 of the assembly bracket. central part 6.

Flangeboringen 12 har stort set samme diameter som møbelpladeboringeme 10,11. Denne diameter svarer stort set til diameteren for en låsestift 1 (se fig. 5). Hver flangeboring 12 er forbundet med et indgangsspor 17, der udmunder ved flangen 5’s sidekant 18. Indgangssporet 17 har en bredde, der er mindre end diameteren af flangeboringen 20 12. Bredden af indgangssporet 17 svarer stort set til en bredde 19 mellem to spor 20, som er anbragt diametralt modstillet i låsestiftens cylindriske legeme. Låsestiften 1 vil således kunne føres ind gennem indgangssporet 17 med de to spors bund 21 anbragt vinkelret på flangen 5’s sidekant 18. Når låsestiften 1 er placeret i flangeboringen 12, kan denne roteres, fortrinsvis gennem en vinkel på 90° til den i fig. 5 viste stilling. Her-25 ved er flangen 5 (og samlebeslaget) fastgjort til en møbelplade 9’s sidekant 8.The flange bore 12 has substantially the same diameter as the furniture plate bores 10,11. This diameter corresponds roughly to the diameter of a locking pin 1 (see Fig. 5). Each flange bore 12 is connected to an input groove 17 which opens at the lateral edge 18 of the flange 5. The input groove 17 has a width less than the diameter of the flange bore 20 12. The width of the input groove 17 corresponds substantially to a width 19 between two grooves 20. which is diametrically opposed to the cylindrical body of the locking pin. Thus, the locking pin 1 can be inserted through the input groove 17 with the bottom grooves 21 located perpendicular to the side edge 18 of the flange 5. When the locking pin 1 is located in the flange bore 12, it can be rotated, preferably through an angle of 90 ° to that of FIG. 5. By this, the flange 5 (and the mounting bracket) is attached to the side edge 8 of a furniture plate 9.

I fig. 5 ses, at der ved overgangen mellem indgangssporet 17 og flangeboringen 12 er en fremspringende del 22, der passerer inden for den ydre cirkel, som beskrives af låsestiften 1. Fremspringet 22 vil ved rotation aflåsestiften 1 komme i anlæg mod sporet 20’s 30 bund 21. Der er således dannet et endestop, som sikrer, at en rotation kun sker gennem 90° på en sådan måde, at sporene 20 stilles på tværs af indgangssporet 17. Herved opnås en sikker indbyrdes fastholdelse.In FIG. 5, it is seen that at the transition between the input groove 17 and the flange bore 12, a protruding portion 22 passes within the outer circle described by the locking pin 1. The protrusion 22 will, by rotation, lock the pin 1 against the bottom 21 of the groove 20. Thus, an end stop is formed which ensures that a rotation occurs only through 90 ° in such a way that the grooves 20 are positioned transversely of the input groove 17. This provides a secure interlocking.

7 DK 171838 B1 I fig. 5 ses endvidere, at indgangssporet 17 er placeret asymmetrisk på en sådan måde, at den ene side 23 forløber tangentielt til den cirkel, som defineres af flangeboringen 12. Låsestiften vil således være fastholdt af den relative lille materialemængde 24, som befinder sig ved den modsatte side af indgangssporet 17. Ved den asymmetriske placering 5 af indgangssporet 17 bliver det, ved rotation af låsestiften 1, muligt at trække flangen 5 ned i bunden af noten 7 og derved trække fremspringet 16’s anlægsflade IS i anlæg imod den plane anlægskant 14. Såfremt et samlebeslag ikke er placeret med flangen helt inde i noten, kan den sidste indtrækning ske ved rotation aflåsestiften 1.7 DK 171838 B1 In fig. 5, it is further seen that the input groove 17 is located asymmetrically in such a way that one side 23 extends tangentially to the circle defined by the flange bore 12. The locking pin will thus be held by the relatively small amount of material 24 which is at the opposite side of the input groove 17. At the asymmetrical location 5 of the input groove 17, by rotating the locking pin 1, it is possible to pull the flange 5 down into the bottom of the groove 7, thereby pulling the abutment surface IS of the projection 16 into contact with the flat abutting edge 14. If a fittings not located with the flange fully inside the groove, the last retraction can be made by rotating the locking pin 1.

10 For at lette indsætningen af låsestiften har låsesporet 17 afrundede hjørner 25 ved flangens sidekant 18. Endvidere er bunden 21 fremstillet med afrundede endedele 26, som forløber i retning mod det modstående spor 20. Der opnås således en lettelse ved låsestiftens indførelse i flangeboringen 12.10 To facilitate insertion of the locking pin, the locking groove 17 has rounded corners 25 at the flange side edge 18. Furthermore, the bottom 21 is made with rounded end portions 26 which extend in the direction of the opposite groove 20. A relief is thus obtained by the insertion of the locking pin into the flange bore 12.

15 Som det fremgår af fig. 2 og 4 er hver flange forsynet med afrundede endedele 27. Flangen 5 har en form og udstrækning svarende til noten 7, som ligeledes er forsynet med afrundede endedele 28. Det ses, at noten 7 har en mindre udstrækning end sidekanten 8. Det ses endvidere, at samlebeslagets centrale del 6 har en udstrækning, der er længere end flangen S, og som svarer til længden på sidekanten 8. Ved en samling af flere mø-20 belplader 9, vil endefladen på den centrale del 6 således være synlig.15 As can be seen from FIG. 2 and 4, each flange is provided with rounded end portions 27. The flange 5 has a shape and extension similar to the groove 7, which is also provided with rounded end portions 28. It is seen that the groove 7 has a smaller extension than the side edge 8. It is furthermore seen Thus, the central part 6 of the fittings has a length which is longer than the flange S and corresponds to the length of the side edge 8. By assembling several furniture plates 9, the end surface of the central part 6 will thus be visible.

I fig. 3 og 4 ses, at møbelpladeboringen 11 er et bundhul. Dette bundhul er dimensioneret, således at en låsestift 1, når den er placeret i anlæg mod bunden af dette hul, vil have sit spor 20 placeret i en position ud for noten 7 og dermed ud for flangen 5. Når møbel-25 plader skal samles, er det således blot nødvendigt at placere en låsestift i hver af mø-belpladeboringeme og orientere denne låsestift med et kærvspor 29 vinkelret på sidekanten 8. Herefter kan flangen indføres i sporet og bliver fastholdt ved en rotation af låsestiften 1.1 den viste udførelsesform for samlebeslaget er der anvendt to flangeboringer. Alternativt vil det være muligt at anvende flere eller blot en enkelt flangeboring. 30 Dette afhænger af møbelpladens størrelse.In FIG. 3 and 4, it is seen that the furniture plate bore 11 is a bottom hole. This bottom hole is dimensioned so that a locking pin 1, when positioned abut the bottom of this hole, will have its groove 20 in a position next to the groove 7 and thus next to the flange 5. When furniture-25 sheets are to be assembled , it is therefore only necessary to place a locking pin in each of the furniture plate bores and orienting this locking pin with a notch groove 29 perpendicular to the side edge 8. Thereafter, the flange can be inserted into the groove and is retained by a rotation of the locking pin 1.1. two flange bores used. Alternatively, it will be possible to use multiple or just a single flange bore. 30 This depends on the size of the furniture plate.

Affasningen 13 ved hjørnerne af møbelpladens sidekant 8 har en sådan størrelse, at den plane anlægsflade 14, der efterlades på hver side af noten 7, har en bredde, som svarer til bredden på fremspringet 16’s anlægsflade 15.1 den viste form har anlægsfladen 15 en relativ lille udstrækning. Det vil imidlertid være muligt at anvende større fremspring.The bevel 13 at the corners of the side edge 8 of the furniture plate is of such a size that the flat abutment surface 14 left on each side of the groove 7 has a width corresponding to the width of the abutment surface 15 of the projection 16. extent. However, it will be possible to use larger projections.

5 Det vil således være muligt at anvende fremspring, der har en størrelse, så bredden på anlægsfladen 15 stort set svarer til hele afstanden mellem et spor og møbelpladens overside. I denne situation vil samlingen af møbelplader alene afhænge af anlægget mellem anlægsfladen 15 og anlægsfladen 14.1 den viste udførelsesform vil samlingen også afhænge af et anlæg mellem affasningeme 13.Thus, it will be possible to use projections having a size such that the width of the abutment surface 15 corresponds substantially to the entire distance between a groove and the top surface of the furniture plate. In this situation, the assembly of furniture panels will depend solely on the abutment between abutment surface 15 and abutment surface 14.1. The embodiment shown will also depend on an abutment between abutments 13.

10 I fig. 6-8 illustreres en låsestift 1 med en stort set cylindrisk form med sporene 20 placeret ved en stilling i overfladen af det cylindriske legeme. Sporene 20 er orienteret parallelt med kærvsporet 29 i låsestiftens ene endeflade.10 In FIG. 6-8 illustrate a locking pin 1 having a generally cylindrical shape with the grooves 20 located at a position in the surface of the cylindrical body. The grooves 20 are oriented parallel to the notch groove 29 in one end face of the locking pin.

15 I fig. 9 og 10 er der illustreret sidebilleder gennem en alternativ udførelsesform for en låsestift 1. Denne låsestift er forsynet med et ringformet fremspring 30 ved hver ende af det cylindriske legeme. Disse ringformede fremspring 30 har en større diameter end diameteren for det cylindriske legeme.In FIG. 9 and 10, side views are illustrated through an alternative embodiment of a locking pin 1. This locking pin is provided with an annular projection 30 at each end of the cylindrical body. These annular projections 30 have a larger diameter than the diameter of the cylindrical body.

20 En sådan låsestift vil være indrettet for at samvirke med en møbelplade, hvor møbelpla-deboringen 10,11 har en diameter svarende til yderdiameteren på de ringformede fremspring 30. Ved anvendelse af en sådan låsestift er det muligt for møbelpladen at arbejde, idet fremspringene 30 kan kompensere for toleranceafvigelser ved at trænge ind i møbelpladen, som fortrinsvis er fremstillet af træ.Such a locking pin will be arranged to cooperate with a furniture plate, the furniture plate bore 10,11 having a diameter corresponding to the outer diameter of the annular projections 30. By using such a locking pin it is possible for the furniture plate to work, the projections 30 can compensate for tolerance deviations by penetrating the furniture plate, which is preferably made of wood.
