Abstract

The spectacle frame comprises a frame (1) and two bows (2) fitted to its outer edges. The joint (3) consists of an elastically bendable joint component, which is connected partly to the frame and partly to one end of each of the bows. The elastic joint component is arranged along the bow inside, and the bow end with the joint comprises a counterpiece limiting the bow rotation outwards from the frame.

Description

502 401 10 15 20 25 30 35 ände på en skalm till en glasögonbåge eller motsvarande från ramen utfällbart organ. 502 401 10 15 20 25 30 35 end of a frame to a spectacle frame or equivalent means of a frame which can be folded out.

Företrädesvis utgörs det elastiska ledorganet av en tråd av plast och uppvisar två trådparter som sträcker sig mellan ramen och respektive skalm eller motsvarande organ, varvid trådparterna är belägna ovanför varandra i ett vertikalplan genom respektive skalm. Tråden kan med fördel vara bygelformig, varvid dess skänklar motsvarar de ovan nämnda trådparterna och är dragna genom var sitt hål i ramen och är införda i var sitt hål i respektive skalm eller motsvarande organ. Trådbygelns parti som sam- manbinder skänklarna, dvs trådparterna, befinner sig där- vid åtkomligt vid ramens ena sida, vilket möjliggör att trådbygeln är âtkomlig och kan avlägsnas vid eventuella reparationer på ramen eller övriga delar.Preferably, the elastic hinge member is constituted by a plastic wire and has two wire portions extending between the frame and the respective shell or corresponding member, the wire portions being located one above the other in a vertical plane through the respective shell. The wire can advantageously be bracket-shaped, its legs corresponding to the above-mentioned parts of the wire and being pulled through their respective holes in the frame and are inserted into their respective holes in the respective shell or corresponding member. The part of the wire bar that connects the legs, ie the wire parts, is then accessible at one side of the frame, which enables the wire bar to be accessible and can be removed in the event of any repairs to the frame or other parts.

Ytterligare detaljer och kännetecken beträffande uppfinningen framgår av beskrivningen till figurblad ne- dan samt av patentkraven.Further details and features regarding the invention appear from the description of the figure sheets below and from the claims.

BESKRIVNING TILL FIGURBLAD Uppfinningen beskrivs nedan i form av ett utfö- ringsexempel i anslutning till bifogade figurblad.DESCRIPTION OF FIGURE SHEETS The invention is described below in the form of an exemplary embodiment in connection with the accompanying figure sheets.

Figur 1 visar en glasögonbåge sedd från sidan.Figure 1 shows a spectacle frame seen from the side.

Figur 2 visar i halvsektion glasögonbågen enligt figur 1 sedd ovanifrån.Figure 2 shows in half section the spectacle frame according to figure 1 seen from above.

Figur 3 visar en led till glasögonbågen enligt figur 1 och 2 uppförstorad.Figure 3 shows a link to the spectacle frame according to Figures 1 and 2 enlarged.

Glasögonbågen enligt figur 1 innefattar en ram 1 försedd med två skalmar 2. Såväl ramen 1 som de båda skalmarna 2 är framställda av härdat acrylglas. Respekti- ve skalm 2 är vridbart fastsatt på ramen 1 med en led 3 genom vilken respektive skalm 2 kan fällas in mot ramen 1. Leden 3 utgörs av elastisk tråd H av plast tillverkad under varumärket Nylon som sträcker sig bygelformigt med två skänklar U.1 från ramens 1 utsida, genom två ovanför varandra belägna hål i ramen 1 och in i två motsvarande ovanför varandra belägna hål i skalmen 2 där trädens U ändar är fastlimmade med ett härdande lim som häftar fast 10 15 20 25 30 35 502 401 såväl vid tråden U som vid materialet i skalmen 2. Tråden U visas på figur 3 dragen i en försänkning på ramens 1 framsida men kan alternativt vara dragen helt utanpå el- ler helt infälld i ramen 1. Skalmen 2 uppvisar en urtag- ning 5 som sträcker sig från leden 3 ett stycke utmed insidan av skalmen 2 varigenom tråden H är till hälften frilagd. Genom denna urtagning tillåts en mjuk böjning av tråden H när skalmen 2 fälls in mot ramen 1 utan att tråden H utsätts för oönskade dragkrafter.The spectacle frame according to Figure 1 comprises a frame 1 provided with two temples 2. Both the frame 1 and the two temples 2 are made of tempered acrylic glass. The respective frame 2 is rotatably attached to the frame 1 with a hinge 3 through which the respective hinge 2 can be folded towards the frame 1. The hinge 3 consists of elastic wire H of plastic made under the brand Nylon which extends in a jumper with two legs U.1 from the outside of the frame 1, through two superimposed holes in the frame 1 and into two corresponding superimposed holes in the frame 2 where the ends of the trees U are glued with a hardening glue which adheres to the wire U as with the material in the frame 2. The wire U is shown in Figure 3 drawn in a recess on the front of the frame 1, but may alternatively be drawn completely on the outside or completely recessed in the frame 1. The frame 2 has a recess 5 extending from the joint 3 a piece along the inside of the shank 2 whereby the wire H is half exposed. This recess allows a soft bending of the wire H when the shell 2 is folded against the frame 1 without the wire H being subjected to undesired tensile forces.

Genom att hålen för tråden H i skalmen 2 är pla- cerade relativt nära skalmens 2 insida utgör skalmens 2 plana ände vid leden 3 ett mothåll mot vridningar utåt från skalmens 2 utfällda normalläge. Ett stödorgan i form av en elastisk tapp 6 av plast är dessutom anordnad, fö- reträdesvis limmad, i en urtagning i ramen 1 så att skal- mens 2 ände stöder mot denna när den vrides utåt. Härige- nom upptas krafterna i leden genom en dragning i tråden U och en sammantryckning av tappen 6. Leden 3 blir inte stum vid vridning av skalmen 2 utåt utan fjädrar genom elasticiteten i tråden H och tappen 6.Because the holes for the wire H in the shank 2 are located relatively close to the inside of the shank 2, the flat end of the shank 2 at the joint 3 constitutes an abutment against rotations outwards from the extended position of the shank 2. A support member in the form of an elastic pin 6 of plastic is furthermore arranged, preferably glued, in a recess in the frame 1 so that the end of the shell 2 abuts it when it is turned outwards. As a result, the forces in the joint are absorbed by a tension in the wire U and a compression of the pin 6. The joint 3 does not become dull when the shaft 2 is turned outwards but springs through the elasticity in the wire H and the pin 6.

Tappen 6 kan även utnyttjas för att justera skalmens 2 ytterläge, dvs skalmarnas 2 inbördes avstånd vid sina fria ändar. Genom att välja olika höga tappar 6 kan avståndet mellan skalmarnas 2 ändar ökas eller min- skas efter behov. Såväl tråden U som tappen 6 kan avlägs- nas med enkla medel t ex i samband med att en skalm 2 brutits av och måste bytas. Det är därför att föredra att tråden U är åtkomlig på ramens 1 framsida t ex via en täckbricka eller liknande som täcker urtagningen i ramen 1 för tråden H.The pin 6 can also be used to adjust the outer position of the shell 2, ie the mutual distance of the links 2 at their free ends. By choosing different height pins 6, the distance between the ends of the shackles 2 can be increased or decreased as needed. Both the wire U and the pin 6 can be removed by simple means, for example in connection with a shackle 2 being broken off and having to be replaced. It is therefore preferable that the wire U is accessible on the front side of the frame 1, for example via a cover plate or the like which covers the recess in the frame 1 for the wire H.

Tråden N kan vara infästad på flera olika sätt i såväl ramen (1) som skalmen (2), vilket dock inte visas på figurerna. Sålunda kan t ex tråden (U) vara fastsatt i skänkeln (2) genom fastklämning med hjälp av ett särskilt klämorgan som i sin tur kan vara fastlimmat eller fast- pressat i skänkeln (2).The wire N can be fastened in several different ways in both the frame (1) and the frame (2), which, however, is not shown in the figures. Thus, for example, the wire (U) can be fixed in the leg (2) by clamping by means of a special clamping member which in turn can be glued or pressed into the leg (2).
