Der kendes et klemskruestykke, soin ved deforme-ring og varmsvejsning er fastgjort til en skâlformet bunddel i en lampefatning, og som har en ringformet klikfjeder, der er gjort fast ved klemskruestykkets ud-5 vendige gevind for at hindre den tilherende motrik pâ klemskruestykket i at losne sig utilsigtet. Den slags klemskruestykker involverer relativt dyre operationer i forbindelse med anvendelsen og især vanskeligheder i forbindelse med lagerforing, og desuden er der taie om 10 en ret svag konstruktion, hvis dimensioner ikke gor den saerlig velegnet til en række forskellige anvendelser.A clamping screw, known by deformation and heat welding, is known to be attached to a shell-shaped bottom part of a lamp mount, and which has an annular snap spring which is secured to the external thread of the clamping screw to prevent the associated motive on the clamping screw from get rid of accidentally. These types of clamping screws involve relatively expensive operations in use and in particular difficulties in storage lining, and moreover, there is a rather weak construction whose dimensions do not make it particularly suitable for a variety of applications.

Opfindelsen angâr et klemskruestykke, som nemt kan samles med en lampefatning og udformes sâledes, at det far en passende styrke og giver fornoden plads til 15 det kabel, der skal fastklemmes.The invention relates to a clamping screw which can be easily assembled with a lamp mount and is designed to provide adequate strength and provide the necessary space for the cable to be clamped.

Nærmere angivet angâr opfindelsen et klemstykke i kombination med en lampefatnings skâldel, der har et hul og mod dette âbne, gennemgâende noter, og hvor der til klemskruestykket horer dels en klikfjeder dannet af en 20 mod drejning i skâldelen fastholdt, flad ring med en ud-stâende, elastisk pal, dels en klembosning med en til anlaeg mod skâldelens bund tjenende flange og en gennem skâldelens hul og fjederringen gâende gevinddel for en lâsemotrik med tænder til indgreb med klikfjederen.Ifolge 25 opfindelsen er et sâdant klemskruestykke ejendommeligt ved, at fjederens flade ring har flige, der ved optagel-se i de gennemgâende noter indgriber med skâldelen, og som tillige kan indgribe drejningshindrende med et hul-parti i et mellemlag mellem skâldelen og fjederen.More particularly, the invention relates to a clamping piece in combination with a lamp part's skid portion having a hole and through said grooves, and in which a clamping spring formed by a pivot spring formed by a flat ring with a protruding ring is associated with an opening. standing, elastic pawl, partly a clamping bush with a flange serving against the bottom of the skull part and a threaded part passing through the hole of the skull and the spring ring for a locking motor with teeth for engagement with the click spring. According to the invention, such a clamping screw is peculiar to the spring of the ring. has tabs which, when included in the through notes, engage with the shoe portion, and which may also engage pivot obstruction with a hole portion in an intermediate layer between the shoe portion and the spring.

30 Det pâgæl'dende mellemlag kan være midterdelen af en lampeskærm, sâ at fligene efter samlingen ikke blot hindrer en drejning mellem fjederringen og lampefatnin-gen, hvilket er en f orudsaetning for klikf jederens tilsig-tede virkning, men ogsâ fastholder lampeskærmen mod at 35 dreje sig.The intermediate layer in question may be the center portion of a lamp shade so that the tabs after assembly not only impede a rotation between the spring ring and the lamp mount, which is a prerequisite for the intended effect of the click spring, but also retains the lamp shade against 35 turn around.

En klikfjeder af métal, som er indrettet med en fjedrende griber, bestâr af en flad ring 5 med en oph0jet, fjedrende griber 5A, to modstâende holdeflige 5B, der udgâr fra ringen 5 og er bukket i en ret vinkel i 10 forhold til ringen 5, sâ at de er parallelle og i det væsentlige anbragt med en afstand svarende til afstanden mellem bunden i noterne 3A. Ringen 5 holdes let an imod en udvendig overflade 3C omkring hullet 3 pâ fatningsdelen 1 ved at anbringe holdefligene 5B i 15 noterne 3A og ved at bukke deres ender i modsat ret-ning af hinanden og i en retning imod den indvendige bund pâ fatningsdelen 1. Den fjedrende griber 5A ligger udaf for pâ denne mâde at være fjedrende oph0jet i forhold til fatningsdelen (se især fig. 1).A metal snap spring fitted with a resilient gripper consists of a flat ring 5 with an raised, resilient gripper 5A, two opposing retaining tabs 5B starting from the ring 5 and bent at a right angle to the ring 5 so that they are parallel and substantially spaced at a distance corresponding to the distance between the bottom of the grooves 3A. The ring 5 is easily held against an outer surface 3C around the hole 3 on the socket part 1 by placing the retaining tabs 5B in the grooves 3A and by bending their ends in the opposite direction of each other and in a direction towards the inner bottom of the socket part 1. The resilient gripper 5A lies out in this way to be resiliently raised relative to the socket member (see in particular Fig. 1).

20 Det egentlige klemskruestykke bestâr af to dele 7 og 9. En klemb0sning 7 har i den ene ende fjedrende kæber 7A og i den anden ende en f lange 7B. Klem-b0sningen 7 har et gevind 7C, som kan være afbrudt af to modsat liggende flader, samt to diametralt liggen-25 de fremspring 7E, som st0der op til flangen 7B.The actual clamping screw consists of two parts 7 and 9. A clamping sleeve 7 has at one end resilient jaws 7A and at the other end a long 7B. The clamping sleeve 7 has a thread 7C which may be interrupted by two opposite faces, as well as two diametrically located projections 7E which abut the flange 7B.

Den samme klemb0sning er vist i fig. 7 og kan ligeledes anvendes uden klikfjederen 5, og den kan an-vendes i en fatningsdel, der enten har et rundt hul el-ler et kantet hul, og i dette tilfælde undgâs drejning 30 af bâde klemb0sningen og éventuelle skiver, som kan være anbragt imellem fatningsdelen og en ringlâsem0trik.
