Abstract

The invention relates to a lamp shade which is easy to mount as well as dismount for packing and transporting at a minimum volume. The shade comprises a shroud 10 stretched between two supporting rings 20, 24 which are retained in a springing way by at least three stiffening braces 40, which are in turn united by a central retainer disc 30. The stiffening braces 40 engage with the supporting rings 20, 24 by means of easily releasable gripping means such as claws 48, and they are also releasably connected or jointed to the retainer disc 30. Hereby, the shade may be dismounted and folded together almost flattened, such that it will in this state demand inconsiderable room in the height. <IMAGE>

Description

¿1ez249-2 2 visar en varierad detalj av sprötet, och fig. 12 slutligen visar en perspek- tivvy av den färdiga lampskärmen enligt uppfinningen, sedd snett underifrån och monterad på en konventionell lamphållare. ¿1ez249-2 2 shows a varied detail of the rod, and Fig. 12 finally shows a perspective tiv view of the finished lampshade according to the invention, seen obliquely from below and mounted on a conventional lamp holder.

I fig. l och 2 visas sålunda själva skärmdelen 10 av en i och för sig konventionellt formad lampskäïzm. Skänndelen är utförd av ett böjligt material, vanligen ett textilmaterial, t.ex. siden eller något annat de- korativt tyg. En skärm av detta slag är ofta i stort sett konisk och sam- mansatt av tre sektorer ll, förenade längs sömmar 12. Skärmen 'air öppen upp- åt och nedåt och avsmalnar uppåt, varvid öppningarna begränsas av nedre och övre fållar 14 resp. 16.Thus, in Figs. 1 and 2, the screen part 10 itself is shown of an in and of itself conventionally shaped lampskäïzm. The scaling part is made of a flexible material, usually a textile material, e.g. silk or any other decorative fabric. A screen of this kind is often largely conical and composed of three sectors ll, joined along seams 12. The 'air open screen' to and down and tapers upwards, the openings being limited by the lower and upper hems 14 resp. 16.

I fig. 3 och 4 visas i lampskäzmen ingående stagringar utförda exem- pelvis av lackerad Järntråd. I fig. 3 visas en nedre trådring 20, varvid ringen .som synes är öppen med den ena fria änden försedd med en liten lås-_ hylsa 22, som är anordnad att uppta trådringens motstående, fria ände 23 och därmed sluta ringemFig. 4 visar på motsvarande sätt en likadan fast mindre trådring 24 med låshylsa 26 och motstående, fri ände 27.In Figs. 3 and 4, stag rings included in the lamp scheme are shown. pelvis of lacquered Iron wire. Fig. 3 shows a lower wire ring 20, wherein ring which appears to be open with one free end provided with a small lock-_ sleeve 22, which is arranged to receive the opposite, free end 23 of the wire ring and thus stop ringemFig. 4 shows in a corresponding manner a similar fixed smaller wire ring 24 with locking sleeve 26 and opposite, free end 27.

Medelst trådringarrxa 20 och 24 stagas skärmdelens lO nedre och övre öppningar genom att respektive ring (på i och för sig känt sätt) trädes ge- nom fållarna 14 resp. l6 längs skär-mens öppningar, varvid givetvis ringar- na är öppna, .så att deras fria, släta ändar 23 resp. 27 kan trädas genom fållarna för att, sedan trädningen avslutats, skJutes in i respektive lås- hylsa 22 och 26, som själv skjutas in i och döljes av tillhörande fåll, se fig. 5. e ' Resultatet blir en lampskärmsdel med stela kanter längs sina övre och nedre, cirkulär-a öppningar, vilka sållmda erhållit sin form och stadga medelst de i fållarna. 14 och 16 upptagna stagringama 20 resp. 24. Tills vidare föreligger inte någon förbindelse mellan båda ringarna sinsemellan, utan hela skärmdelen kan fällas ihop platt, såsom åskådliggöres i fig. 5, under upptagande av ett minimalt utrynune i höjdled.By means of wire ring rows 20 and 24, the lower and upper parts of the screen part 10 are braced openings by inserting the respective ring (in a manner known per se) nom hills 14 resp. 16 along the openings of the screen, the ring na are open, so that their free, smooth ends 23 resp. 27 can be threaded through the hems so that, after threading is completed, they are slid into the respective sleeve 22 and 26, which itself is pushed into and hidden by the associated hem, see Fig. 5. e ' The result is a lampshade part with rigid edges along its upper ones and lower, circular openings, which have thus obtained their shape and stability by means of those in the folds. 14 and 16 occupied the retaining rings 20 and 24. Tills furthermore, there is no connection between the two rings, without the whole screen part can be folded flat, as illustrated in Fig. 5, while recording a minimal utrynune in height.

I fig. 6-8 visas hur en i lampskäzmen enligt uppfirmingen ingående central hållarbricka är anordnad. Denna består av två lika, cirkulära hal- vor 32, se fig. 6, som visar den ena brickhalvan i ungefär naturlig stor- lek. Halvorna läggs samman som fig. 7 visar och förenas med varandra, t.ex. medelst punmsvetsning om brickhalvorna utföres av tunn metallplåt. Såsom framgår av figurerna är varje brickhalva 32 försedd med radiella, längs brick- halvans kant lika fördelade präglingar 34, och när brickhalvorna förenas bil- dar präglingarna parvis radiella hylsor 56, för ett ändamål som skall be- slu-ivas. I detta sammanhang framhållas att brickhalvorna kan utföras av plast och förenas medelst bindemedel, eller hållarbrickaxi 30 kan i sin helhet 5 s1ez249-2 formpressas eller formsprutas av plastmaterial. Den färdiga hållarbriokan 30 visas i planvy i fig. 8, och som synes har brickan en central öppning 33.Figs. 6-8 show how one is included in the lamp scheme according to the invention central holding washer is arranged. This consists of two equal, circular halves 32, see Fig. 6, which shows one half of the tray in approximately natural size. play. The halves are folded together as Fig. 7 shows and joined together, e.g. by punch welding if the washer halves are made of thin metal sheet. As As can be seen from the figures, each tray half 32 is provided with radial, along the tray the edge of the half evenly distributed embossments 34, and when the tray halves are joined the embossments in pairs radial sleeves 56, for a purpose to be determined slu-ivas. In this context, it is emphasized that the tray halves can be made of plastic and joined by binder, or holder washer 30 in its entirety 5 s1ez249-2 compression molded or injection molded from plastic material. The finished holder brioca 30 is shown in plan view in Fig. 8, and apparently the tray has a central opening 33.

I fig. 9 visas ett sista, i lampskäxmen enligt uppfinningen ingående element, nämligen ett stagspröt 40, som i detta fall består av lackerad .jämtråd. Denna är bockad så., att sprötet bildar två sinsemellan i stort sett vinkelräta skänklar, en horisontell, svagt böjd skähkel 42 och en rak, vertikal skänkel 44. Vid föreningen mellan skënklaxna är den vertikala om- bockad ett kort stycke och längs detta förenat med den horisontella skän- keln 42, så att de förenade trådpartiema tillsammans bildar en utskjutan- de ttmga 46, såsom framgår av fig. 9 ooh 9a. Sprötet kan givetvis också formas av en enda tråd, som ledes nmt i den konfiguration som de nämnda figurerna visar. vid den fria änden av vardera skänkeln 42 och 44 är en liten klo 48 fastsvetsad, varvid klorna till sin storlek är avpassade att gripa om tråd- materialet i stagringarna 20 och 24, såsom skall beskrivas. Alternativt kan av plast utförda klor 50 enligt fig. ll användas, varvid dessa är utformade med ett litet hylsparti 52, som påskJutes skëlnklarnas42 och 44 fria ändar.Fig. 9 shows a final element included in the lampshade according to the invention element, namely a tie rod 40, which in this case consists of lacquered .jämtråd. This is bent so that the rod forms two between each other in a large way perpendicular legs, a horizontal, slightly curved shank 42 and a straight, vertical leg 44. At the junction between the hamstrings, the vertical circumference is bent a short distance and along it joined to the horizontal slope 42 so that the joined wire portions together form a protrusion the ttmga 46, as shown in Figs. 9 and 9a. The rod can of course also formed by a single wire, which is guided nmt in the configuration as mentioned the figures show. at the free end of each leg 42 and 44 is a small claw 48 welded, the claws being sized to grip the wire. the material of the retaining rings 20 and 24, as will be described. Alternatively can plastic claws 50 according to Fig. 11 can be used, these being formed with a small sleeve portion 52, which EasterJutes the sheaths42 and 44 free ends.

I lJuset av ovanstående detaljbeslcrivning torde lätt inses hur lamp- skäzmen enligt uppfinningen spännes upp och färdigställas. I skär-mens stom- me ingår tre av de nyss beskrivna spröten 40, vilka vart och ett förenas med den centrala hållarbriokan 30 genom att deras tungor 46 skjutes i brickans hylsor 36, såsom åskådliggöres i fig. lO. De tre klor 48 som be- finner sig vid de vertikala sprötskäiiklamas 44 övre ändar bringas att in- gripa med den övre stagringen 24, som sålunda är insatt i skërmaterialets lO övre fåll 16, såsom tidigare beskrivits. Härvid bemärkes att vid ändarna av de sömmar 12 som förenar det i tre sektioner ll uppdelade skärmmaterialet lO har små öppna, dvs. ej hopsydda partier lämnats, såsom något överdrivet visas vid 12' och l2" i fig. l och 2. Klorna 48 på stagskëlrzklaznas 44 övre ändar kan således komma åt att gripa om den övre stagringen 22 genom de, nämnda öppna partierna 12" i fållen 16.In the light of the above detailed description, it will be readily apparent how the scheme according to the invention is tensioned and completed. In the cutting frame me includes three of the rods 40 just described, each of which is joined with the central holder brioca 30 by sliding their tongues 46 into the sleeves 36 of the washer, as illustrated in Fig. 10. The three chlorine 48 located at the upper ends of the vertical rod ice caps 44 are caused to grip with the upper retaining ring 24, which is thus inserted into the cutting material 10 upper hem 16, as previously described. It is noted that at the ends of the seams 12 joining the screen material divided into three sections 11 10 has small open, ie. unassembled lots have been left, as something exaggerated shown at 12 'and 12 "in Figs. 1 and 2. The claws 48 on the upper of the stagskëlrzklaznas 44 ends may thus be able to grip the upper retaining ring 22 through the said open portions 12 "in the hem 16.

Sista steget i monteringen sker genom att de horisontella spröt- skänklaznas 42 klor 48 på analogt sätt bringas att ingripa med den nedre, i skärmmaterialets 10 nedre fåll l4 upptagna stagringen 20, varvid klorna även här kornmer åt ringen genom de öpma partier 12' som länmats i fållen 14. Härvid är de horisontella, något böjda sprötskäzxklarnas 42 längd så av- passad, att deras klor 48 före monteringen ligger något utanför den nedre stagringens 20 omkrets; sprötskänklazna 42 måste således böjas ytterligare något för att deras klor skall lnrma gripa om stagringen, och således kom- mer skänklazna att utöva en radiellt utåt riktad spähnkraft på stagringen I 81932 49-2 4 20. Denna kraft kommer att upptas av skärmmaterialet 10 mellan de båda stag- ríngarna 20 och 24, så att skärmen sträcks ut mellan ringarna.The last step in the assembly takes place by the horizontal the claws 48 of the skänklaz 42 are brought into engagement with the lower one in an analogous manner, in the lower hem of the screen material 10, the retaining ring 20 received, the claws here, too, the ring adheres to the ring through the open portions 12 'which are left in the hem 14. In this case, the length of the horizontal, slightly curved rod joints 42 is so fit, that their claws 48 before mounting are slightly outside the lower one the circumference of the stay ring 20; thus, the rod leg claws 42 must be further bent something to prevent their claws from gripping the strut ring, and thus more skänklazna to exert a radially outwardly directed tension force on the strut ring I 81932 49-2 4 20. This force will be absorbed by the screen material 10 between the two struts. rings 20 and 24, so that the screen extends between the rings.

Slutresultatet åskådliggöres i fig. 12. I änden på en pelare 62, t.ex. ingående i en golv- eller bordslampa, är en konventionell lamphållare 60 med glödlampa 64 anordnad. Lampskärmens hållarbricka 30, vars öppning 58 har standardiserad storlek, upptas på konventionellt sätt på lamphållaren och spännes fast på denna medelst det vanliga skruvförbandet. Från hållar- brickan utgår de tre stagspröten 40, vilkas klor 48 (eller 50) ingriper med de nedre och övre stagringarna 20 resp. 24 vid sömmarnas 12 ändar och strävar att föra ringarna ifrån varandra, vilket motverkas av materialet i själva lampskärmen 10, som således hålles utsträckt och slät.The end result is illustrated in Fig. 12. At the end of a pillar 62, e.g. included in a floor or table lamp, a conventional lamp holder 60 is included light bulb 64 arranged. The lampshade holder tray 30, the opening 58 of which has standardized size, accommodated in a conventional manner on the lamp holder and fastened to it by means of the usual screw connection. From the holder the washer releases the three stay rods 40, the claws 48 (or 50) of which engage with the lower and upper retaining rings 20 resp. 24 at the ends of the seams 12 and strives to move the rings apart, which is counteracted by the material in the lampshade 10 itself, which is thus kept extended and smooth.

Såsom tidigare framhållits utgör den ovan beskrivna lampskärmen en-I dast ett exempel på uppfinningen, och inom dennas ram torde fackmannen kum- na föreslå ett flertal variationer och modifikationer. Sålunda behöver an- talet stagspröt inte vara begränsat till tre, utan särskilt vid tyngre skär- mar kan ett större antal användas. Vid längre tillverkningsserier kan också spröten som helhet formpressas i plast med klor, skänklar och tugor i ett stycke. Vidare kan den visade kopplingen av typ tapp-hylsa mellan spröten och hållarbrickan ersättas av gångleder på sådant sätt, att spröten permanent hänger samman med brickan och vid demonteringen kan fällas ned i brickans plan, varvid vridningsaxeln sträcker sig radiellt i förhållande till hållar- brickan. Även andra variationsmöjligheter föreligger, och uppfinningen är så- ledes icke begränsad till den visade och beskrivna utföringsformen utan om- fattar alla former och varianter som faller uder definitionerna i följande patentkrav.As previously pointed out, the lampshade described above constitutes a-I is an example of the invention, and within its scope, those skilled in the art should propose a number of variations and modifications. Thus, the number of rods should not be limited to three, but especially for heavier a larger number can be used. For longer production series can also the rods as a whole are molded in plastic with claws, legs and bits in one paragraph. Furthermore, the shown coupling of type pin-sleeve between the rods can and the holding washer is replaced by hinges in such a way that the rods are permanent is connected to the washer and during disassembly can be folded down into the washer plane, the axis of rotation extending radially relative to the holder the tray. Other possibilities for variation also exist, and the invention is thus is not limited to the embodiment shown and described, but takes all forms and variants that fall under the definitions in the following patent claims.
