Den foreliggende opfindelse angår et møbelben af den i krav l's indledning angivne art.The present invention relates to a furniture leg of the kind set forth in claim 1.

Et sådant møbelben kendes fra DE fremlæggelsesskrift nr. 11 62 983, hvor de mod hinanden bevægelige ben i upåvirket 5 tilstand indtager en stilling, som stemmer overens med den stilling, benene har, når deres indgrebsorganer (tunger) samvirker med indgrebsorganerne (udskæringer) på møblet.Such a furniture leg is known from DE presenting specification No. 11 62 983, in which the movable legs in unaffected condition occupy a position which corresponds to the position of the legs when their engaging means (tongues) cooperate with the engaging means (cuts) of the furniture.

Ved fastgørelse af et sådant ben fastgøres tungerne i de tilsvarende udskæringer ved, at benets indbyrdes bevægelige 10 ben deformeres, hvorefter disse slippes, og den iboende fjederkraft fører benene tilbage til sådanne stillinger, at tungerne fastholdes i udskæringerne i beslaget. For at man blot nogenlunde sikkert kan garantere en god forbindelse mellem møbelbenet og møblet, er det nødvendigt, at den an -15 vendte fjederkraft ved indpresning af tungerne i udskæringerne er af en væsentlig størrelse. I praksis forårsages dette ved, at i hvert fald benets øvre dele er fremstillet af fjedrende materiale.In attaching such a leg, the tongues are fastened in the corresponding cuts by deforming the mutually movable 10 legs, after which they are released and the inherent spring force returns the legs to such positions that the tongues are retained in the cuts in the bracket. In order to guarantee a good connection between the furniture leg and the furniture, it is quite certain that the spring force applied when pressing the tongues in the cutouts is of considerable size. In practice, this is caused by at least the upper parts of the leg being made of resilient material.

Ulempen ved denne kendte konstruktion er, at den kraft, som 20 kræves til at modvirke spændkraften fra benets øvre dele ved monteringen af benet, er væsentlig, hvilket medfører, at monteringen af benet kun kan udføres med stor vanskelighed. Endvidere er det umuligt trods den store spændkraft efter langvarig slitage, eksempelvis i forbindelse med vi- 25 brationer, at sikre, at benets fastgørelse på møblet bliver upåklagelig. Dette skyldes, at den ovenfor skitserede konstruktion til sin funktion ud over den store spændkraft også er afhængig af meget stor præcision såvel med hensyn til tungerne som til udskæringerne.The disadvantage of this known construction is that the force required to counteract the tensile force of the upper parts of the leg in mounting the leg is substantial, which means that the mounting of the leg can only be performed with great difficulty. Furthermore, despite the high tension force after long-term wear, for example in vibrations, it is impossible to ensure that the leg's attachment to the furniture becomes impeccable. This is because the structure outlined above for its function, in addition to the high tensile force, also depends on very high precision in terms of both the tongues and the cuts.

30 Den foreliggende opfindelses formål er at anvise en anordning for løsbar forbindelse af et møbelben med et møbel på en sådan måde, at de ovenfor skitserede ulemper ved tidligere kendte konstruktioner af denne art elimineres.The object of the present invention is to provide a device for releasably connecting a piece of furniture with a furniture in such a way as to eliminate the disadvantages outlined above in prior art designs of this kind.

Dette opnås ifølge opfindelsen ved den i krav 1 anviste konstruktion.This is achieved according to the invention by the construction of claim 1.

Ved en praktisk udførelsesform er møblet forsynet med et beslag, som har to grupper ud for hinanden i fra møblets 5 underside nedadrettede ben udformede udskæringer til optag else af tunger, der er i det væsentlige parallelle med møblets underside og placeret på to bevægelige ben af møblet. Ifølge opfindelsen foreslås i denne forbindelse, at låseorganet er pladeformet og indrettet til ved indføring mellem 10 benene at presse disse fra hinanden til indtagelse af en låsestilling parallelt med møblets underside og i anlæg mod denne eller mod en beslagets ben forbindende plade.In a practical embodiment, the furniture is provided with a bracket which has two groups adjacent to each other in cut-out legs formed from the underside of the furniture 5 to receive tongues substantially parallel to the underside of the furniture and located on two movable legs of the furniture. . According to the invention, in this connection, it is proposed that the locking means is plate-shaped and arranged to push them apart between the 10 legs to take a locking position parallel to the underside of the furniture and abutting against it or against a plate connecting leg.

For at sikre fastholdelse af låseorganet i dets låste stilling er det ifølge opfindelsen fordelagtigt,at benets øvre, 15 i forbindelse med tungerne beliggende dele, konvergerer i retning nedad,således at der mellem disse dele og beslagets plade dannes et underskåret rum, i hvilket låseorganet kan indføres og fastholdes ved elastisk deformation af benets øvre dele og/eller låseorganet.In order to ensure retention of the locking member in its locked position, it is advantageous according to the invention that the upper parts of the leg, in conjunction with the tongues, converge in a downward direction so that a cut space is formed between these parts and the plate of the bracket, in which the locking member may be inserted and retained by elastic deformation of the upper parts of the leg and / or the locking means.

20 Opfindelsen skal i det følgende forklares nærmere i for bindelse med tegningen, hvor fig. 1 viser et beslag, som er beregnet til fastgørelse på undersiden af et møbel, og en øvre del af et møbelben, som er udformet til at virke sammen med besla-25 get, fig. 2 samme set fra siden, fig. 3 viser montering af benet i beslaget, fig. 4 viser det færdigmonterede ben, fig. 5 viser montering under anvendelse af et nogetBRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail in connection with the drawing, in which 1 shows a bracket intended for fastening to the underside of a piece of furniture and an upper part of a piece of furniture that is designed to work with the bracket; FIG. 2 is a side view, FIG. 3 shows the mounting of the leg in the bracket; FIG. 4 shows the pre-assembled leg; FIG. 5 shows mounting using a somewhat

- 3 - modificeret låseorgan, fig. 6 i monteret tilstand en noget modificeret udførelsesform for såvel benets øvre del som selve låseorganet, og 5 fig.7 og 8 endnu en udførelsesform for opfindelsen.- 3 - modified locking means, fig. 6 shows in a mounted state a somewhat modified embodiment of the upper part of the leg as well as the locking means itself, and in Figs. 7 and 8 a further embodiment of the invention.

Som det fremgår af fig. 1, omfatter opfindelsens genstand et beslag, som har en plade 1, der er beregnet til fastgørelse eksempelvis ved hjælp af skruer mod undersiden af et møbel. Fra pladen 1 strækker sig nedad to ben 2 og 3, der 10 står i det væsentlige vinkelret på pladen og er indbyrdes parallelle. Benene 2 og 3 er forsynet med hver et sæt udskæringer 4, hvorved benet 3 i den viste udførelsesform har to udskæringer. Også benet 2 har, selv om det ikke fremgår af tegningen, to tilsvarende udskæringer. Naturligvis kan 15 et andet antal udskæringer forekomme. Selve møbelbenets øvre del er udformet som to ben 5 og 6,der er bevægelige væk fra og mod hinanden under let manuel påvirkning. De øvre ender af benene er forsynet med fremspringende tunger 7, der er udformet på en sådan måde, at de med god pasning 20 kan optages i beslagets udskæring 4. Hensigtsmæssigt kan tungerne være noget kileformede, således at deres frie ender har noget mindre materialetykkelse end deres indre ender ved benene 5 henholdsvis 6. I møbelbenets monterede tilstand befinder benene 5 og 6 sig inde mellem beslagets 25 ben 2 og 3, hvorved tungerne 7 er optaget i udskæringen 4 i beslagets ben.As shown in FIG. 1, the object of the invention comprises a bracket having a plate 1 intended for fastening, for example, by means of screws against the underside of a piece of furniture. From plate 1 extends downwardly two legs 2 and 3, 10 being substantially perpendicular to the plate and mutually parallel. The legs 2 and 3 are each provided with a set of cuts 4, whereby the leg 3 in the illustrated embodiment has two cuts. Also the leg 2, although not shown in the drawing, has two corresponding cuts. Of course, a different number of cuts may occur. The upper part of the furniture leg itself is designed as two legs 5 and 6 which are movable away from and towards each other under slight manual action. The upper ends of the legs are provided with projecting tongues 7 formed in such a way that they can be accommodated with good fit 20 in the cutout 4. Suitably the tongues may be somewhat wedge-shaped, so that their free ends have a somewhat less material thickness than their inner ends at the legs 5 and 6. In the mounted state of the furniture leg, the legs 5 and 6 are located between the legs 2 and 3 of the bracket 25, whereby the tongues 7 are received in the cutout 4 in the legs of the bracket.

Som det fremgår af fig. 2, er det fordelagtigt, at afstanden mellem de fra hinanden vendte kanter af over for hinanden beliggende tunger 7 er noget mindre end den indvendige 30 afstand mellem beslagets ben 2 og 3. Imidlertid er denne afstand ifølge opfindelsen ikke af nogen særlig betydning, eftersom det forudsættes, at benene 5 og 6 er let bevægelige ved manuel påvirkning mod og væk fra hinanden. En sådanAs shown in FIG. 2, it is advantageous that the distance between the facing edges of opposite tongues 7 is somewhat smaller than the internal distance between the legs 2 and 3. However, this distance according to the invention is of no particular importance since it is assumed that the legs 5 and 6 are easily movable by manual action towards and away from each other. One

- 4 - bevægelighed af benene 5 og 6 kan ifølge opfindelsen lettest afstedkommes, enten ved, at benene ved hjælp af hængselanordninger er fastgjort til en stiv underdel eller ved, at de er fremstillet af et sådant materiale eller udformet 5 på en sådan måde, at de på grund af deres egen bøjelighed bliver let bevægelige. Det fremgår også af fig.2, at tungernes 7 tværsnit hensigtsmæssigt er noget kileformet.- 4 - movement of the legs 5 and 6 can according to the invention be most easily achieved, either by the legs being secured to a rigid base by means of hinges or by being made of such material or shaped 5 in such a way that they, because of their own flexibility, become easily movable. It is also apparent from Fig. 2 that the cross-section of the tongues 7 is suitably somewhat wedge-shaped.

Ved montering af møbelbenet i beslaget 1 føres, som det fremgår af fig. 3, det ene bens 6 to tunger 7 ind i udskæ-10 ringen 4 i beslagets ene ben 3. Derefter anbringes i det hjørne,som afgrænses af beslagets plade 1 og benet 6,et låseorgan 8, som hensigtsmæssigt kan have rektangulær form.When mounting the furniture leg in the bracket 1, as shown in FIG. 3, the two tongues 7 of one leg 6 into the cutout 4 in one leg of the bracket 3. Then, in the corner bounded by the plate 1 of the bracket and the leg 6, a locking member 8 which can suitably be rectangular in shape is placed.

Ved svingning af låseorganet 1 i pilens A retning presses det andet ben udad, så at dets tunger 7 kommer i indgreb 15 med udskæringen 4 i beslagets ben 2. I denne stilling har låseorganet indtaget en stilling, som befinder sig omtrent midt mellem stillingen ifølge fig. 3 og 4. Ved fortsat svingning af låseorganet 8 i retning af pilen A vil låseorganet snappe over og blive indført i det underskårne rum, 20 som begrænses af de øverste dele af benene 5 og 6 og beslagets plade 1 (se fig.4). Denne snapvirknng forårsages ifølge opfindelsen hensigtsmæssigt enten ved, at låseorga^ net er fremstillet af et i nogen grad elastisk materiale, som er deformerbart, eller ved, at materialet i benet 5 i 25 en vis grad deformeres. Naturligvis er det også muligt, at snapvirkningen fremkommer ved en kombination af de ovenfor nævnte deformationsalternativer.By pivoting the locking member 1 in the direction of arrow A, the second leg is pressed outwardly so that its tongues 7 engage 15 with the cutout 4 in the leg of the bracket 2. In this position, the locking member has taken a position which is approximately midway between the position according to FIG. . 3 and 4. Upon continued pivoting of the locking member 8 in the direction of the arrow A, the locking means will snap over and be inserted into the cut space 20, which is limited by the upper parts of the legs 5 and 6 and the plate 1 of the bracket (see Fig. 4). This snap action according to the invention is conveniently caused either by the locking member being made of a somewhat resilient material which is deformable, or by the material of the leg 5 being deformed to some extent. Of course, it is also possible that the snap effect is obtained by a combination of the aforementioned deformation alternatives.

I fig. 4 vises møbelbenet monteret i beslaget. Herved fremgår det tydeligt, at låseorganet 8 er optaget i et under-30 skåret rum, som begrænses af nedad konvergerende dele af benene 5 og 6 samt af beslagets plade 1. I denne stilling presses endvidere benene 5 og 6 sikkert fra hinanden, hvilket indebærer, at tungerne 7 ikke har nogen som helst mulighed for at komme ud af indgreb med udskæringerne i be- 35 slagets ben 2 og 3 eller for at rasle i disse. For at sikreIn FIG. 4 shows the furniture leg mounted in the bracket. Hereby it is clearly seen that the locking member 8 is accommodated in an undercut space which is limited by downwardly converging parts of the legs 5 and 6 and by the plate plate 1. In this position, the legs 5 and 6 are furthermore pressed securely apart, which implies that the tongues 7 have no opportunity whatsoever to come out of engagement with the cuts in the legs 2 and 3 of the bracket or to rattle in them. To secure

- 5 - så god indpresning som muligt af benene 5 og 6 udad mod beslagets ben er det ifølge opfindelsen fordelagtigt, at låseorganet 8 er fremstillet af et forholdsvis hårdt, men i nogen grad elastisk materiale, hvilket giver en forbedring 5 af låseorganets fastholdelse og en forøgelse af indpres- ningskraften mod benene 5 og 6.According to the invention, it is advantageous that the locking member 8 is made of a relatively hard but somewhat resilient material, which provides an improvement 5 of the locking means and a increasing the compressive force against legs 5 and 6.

I fig. 5 vises en noget modificeret udførelsesform af låseorganet 8, hvor dette ikke er helt plan, men har et krumt midterparti 9, hvorved låseorganets overside på midten får 10 en pukkel 10, som - når låseorganet svinges opad i retning af pilen A (fig.3) - bringes til anlæg mod beslagets plade 1. Ved at låseorganet 8 endvidere er fremstillet af et stift, i nogen grad elastisk materiale, vil låseorganets endedele blive presset i retning nedad fra pladen 1, dvs. i 15 den retning, i hvilken rummet mellem benene 5 og 6 konvergerer. Herved fremkommer en forøget spændkraft udad mod begge benene 5 og 6.In FIG. 5, a somewhat modified embodiment of the locking member 8 is shown, which is not completely planar, but has a curved middle portion 9, whereby the upper side of the locking means in the middle 10 receives a hump 10 which - when the locking means is swung upwards in the direction of arrow A (Fig. 3 ) - brought to abutment against the plate plate 1. By the locking means 8 further being made of a rigid, somewhat elastic material, the end parts of the locking means will be pressed downwards from the plate 1, ie. in the direction in which the space between the legs 5 and 6 converges. This results in an increased tension force outward towards both legs 5 and 6.

I fig. 6 vises yderligere en modifikation, hvor benene i deres øverste ender umiddelbart under tungerne 7 har 20 afviklede dele 11, der medfører, at konvergensvinklen for det underskårne rum umiddelbart under beslagets plade 1 bliver betydeligt stejlere. I denne udførelsesform har låseorganet 8 endekanter 12, som er skrå, således at de i det væsentligste fuldstændigt kan ligge an mod de krumme 25 dele 11 på benene 5 og 6. I denne udførelsesform er det næppe muligt at svinge låseorganet 8 til låsende stilling på den måde, som vist i fig. 3 ved pilen A. I stedet må låseorganet skydes ind i et plan parallelt med beslagets plade 1. For at sikre en meget god spændkraft i denne ud-30 førelsesform er det også ifølge opfindelsen muligt at gøre låseorganet 8 noget kileformet i indføringsretningen, således at afstanden mellem de skrå kantflader 12 er noget mindre i den ende af låseorganet 8, som først indføres mellem benene 5 og 6, end ved den ende af låseorganet, som 35 sidst indføres mellem benene. Det er også ifølge opfindel-In FIG. 6, a further modification is shown in which the legs at their upper ends immediately below the tongues 7 have 20 unwound portions 11, which cause the angle of convergence of the undercut space immediately below the plate 1 of the bracket to be considerably steeper. In this embodiment, the locking member 8 has end edges 12 which are inclined so that they can substantially completely abut against the curved portions 11 of the legs 5 and 6. In this embodiment, it is hardly possible to swing the locking member 8 into a locking position on the manner shown in FIG. 3, by arrow A. Instead, the locking means must be pushed into a plane parallel to the plate plate 1. In order to ensure a very good tensioning force in this embodiment, it is also according to the invention possible to make the locking member 8 somewhat wedge-shaped in the direction of insertion, so that the distance between the inclined edge faces 12 is somewhat smaller at the end of the locking means 8 which is first inserted between the legs 5 and 6 than at the end of the locking means which is last inserted between the legs. It is also according to the invention that

- 6 - sen muligt at udforme beslagets ben 2 og 3 med en tilsvarende kileform og at give benene 5 og 6 en tilsvarende udformning, hvorved kileformen i dette tilfælde kan være så lille, at den ikke påvirker møbelbenets gode formgivning.- 6 - it is possible to design the legs 2 and 3 of the bracket with a corresponding wedge shape and to give the legs 5 and 6 a similar design, whereby the wedge shape in this case may be so small that it does not affect the good design of the furniture leg.

5 Ved en alternativ, i fig. 7 og 8 vist udførelsesform, er pladen 1 forsynet med en nedadrettet hage 13, som er udformet til at indgribe i en slidseformet udskæring 14 i låseorganet. Som det fremgår af fig. 8, er låseorganet i ubelastet tilstand bueformet fra pladen 1 og hagen 13 og be-10 står af fjedrende materiale, som eksempelvis metal eller plast. Når benene 5 og 6 er bragt i stilling i udskæringerne 4, og låseorganet 8 er anbragt i den i fig.5 In an alternative, in FIG. 7 and 8, the plate 1 is provided with a downwardly facing hook 13 which is designed to engage a slit-shaped cut-out 14 in the locking means. As shown in FIG. 8, the locking means is in an unloaded state arc-shaped from the plate 1 and the hooks 13 and 10 are made of resilient material, such as, for example, metal or plastic. When the pins 5 and 6 are positioned in the cutouts 4 and the locking member 8 is placed in the position shown in FIG.

8 viste stilling, trykes låseorganets midterparti mod pladen, således at hagen vil strække sig gennem udskæringen 14, hvorved låseorganet forskydes, således at 15 hagen kommer til at indgribe med udskæringens kant. I denne stilling fastholdes således låseorganet af hagen, hvorved låseorganets hvælvning er væsentligt mindre, og dets endedele er ført fra hinanden, således at benene 5 og 6 sikkert presses til indgreb med beslagets ben 2 og 3, og 20 tungerne 7 befinder sig fikserede i udskæringerne 4.8, the middle portion of the locking member is pressed against the plate so that the chin will extend through the cutout 14, thereby displacing the locking member so that the chin will engage the edge of the cutout. Thus, in this position, the locking means is retained by the chin, whereby the arch of the locking member is substantially smaller and its end portions are spaced apart so that the pins 5 and 6 are securely pressed into engagement with the pins 2 and 3 and the tongues 7 are fixed in the cutouts. 4th

Låseorganets 8 stilling kan fikseres eksempelvis ved, at midterområdet af låseorganet 8 forsynes med en gænget, gennemgående boring, i hvilken en skrue er anbragt. Ved til-spænding af denne skrue vil låseorganet blive presset nedad 25 fra beslagets plade 1, hvorved ekspansionskraften mod benene 5 og 6 forstærkes på grund af disses konvergens, samtidig med at låseorganet 8 holdes sikkert på plads.The position of the locking member 8 can be fixed, for example, by providing the middle region of the locking member 8 with a threaded through bore in which a screw is placed. By tightening this screw, the locking means will be pressed downwardly 25 from the plate 1 of the bracket, thereby increasing the expansion force against the legs 5 and 6 due to their convergence, while keeping the locking means 8 securely in place.

Ifølge opfindelsen er det også muligt, at tungerne 7 på de indbyrdes bevægelige ben 5 og 6 udefra griber ind i udskæ-30 ringerne 4 på beslaget. I dette tilfælde vil låseorganet 8 ikke blive indført mellem benene 5 og 6, men er hensigtsmæssigt udformet som en bøjle eller et lignende organ, som ude fra presses mod benene 5 og 6, således at disse pressesAccording to the invention, it is also possible that the tongues 7 of the mutually movable legs 5 and 6 from the outside engage in the cut-outs 4 on the bracket. In this case, the locking member 8 will not be inserted between the legs 5 and 6, but is conveniently designed as a bracket or similar means which is pressed outwardly from the legs 5 and 6 so that they are pressed

I denne variation af opfindelsen er hensigtsmæssigt benene 5 og 6 i deres øverste ender i retning fra beslagets plade 1, hvorved bøjlen fastholdes i den låsende stilling. .Conveniently, in this variation of the invention, the legs 5 and 6 are at their upper ends in the direction from the plate 1 of the bracket, whereby the bracket is held in the locking position. .
