L'invention est exposée ci-aprés plus en détail à l'aide de deux dessins représentant le dispositif mécanique lors de l'encastrement des deux culots à vis ou à baionnette des lampes électrique. The invention is set out below in more detail with the aid of two drawings representing the mechanical device during the embedding of the two screw or bayonet bases of the electric lamps.

La figure 1 représente, en perspective à coupes particulières, la douille polyvalente, pendant l'encastrement du culot de la lampe à baïonnette
La figure 2 représente, en perspective à coupes particulières, la douille polyvalente, pendant l'encastrement du culot de la lampe à vis.Figure 1 shows, in perspective with particular sections, the versatile socket, during the fitting of the base of the bayonet lamp
Figure 2 shows, in perspective with special sections, the versatile socket, during the fitting of the base of the screw lamp.

Les deux figures représentent la douille polyvalente et pendant l'encastrement du culot de la lampe à baïonnette et le culot de la lampe à vis. Cette douille est obtenue en ef fectuant le montage suivant : --- On assemble le piston Cbroche) 1 à lame et le piston 2 (broche), on passe les deux parties mobiles 7 et 8 des deux pistons 1 et 2, puis par serrage les deux parties immobiles moletées 9 et 10. Dans les deux alesages 4 et 5, l'alesage 5 ce suit le long du tube cylindrique 11. Puis on assemble la lame 12 en vissant l'alesage fileté 13 de la lame 12, avec le bout fileté 14 de la partie mobile 17. La distance de translation du piston 1 est superieureà celle du piston 2, car la distance de translation de ce dernier est limitée.Puis on assemble les deux-vis à tête fendues 15 et 16 dans les deux alesages fileté 17 et 18, qui sont perpendiculaireS sur les deux alesages 19 et 20, où se logent les deux fils électriques la phase et le neutre. Le profilé 21 isole électriquement la partie neutre. Tout cela sur la pièce porte pistons 22.  The two figures show the versatile socket and during the fitting of the bayonet lamp base and the screw lamp base. This bushing is obtained by performing the following assembly: --- We assemble the piston Cbroche) 1 with blade and the piston 2 (pin), we pass the two moving parts 7 and 8 of the two pistons 1 and 2, then by tightening the two stationary knurled parts 9 and 10. In the two bores 4 and 5, the bore 5 follows along the cylindrical tube 11. Then the blade 12 is assembled by screwing the threaded bore 13 of the blade 12, with the threaded end 14 of the movable part 17. The translation distance of the piston 1 is greater than that of the piston 2, because the translation distance of the latter is limited. Then the two slotted head screws 15 and 16 are assembled in the two threaded bores 17 and 18, which are perpendicular to the two bores 19 and 20, where the two electric wires accommodate the phase and the neutral. Profile 21 electrically isolates the neutral part. All this on the piston holder part 22.

--- On assemble la pièce porte pistons 22 avec la chemise 23, dans le lamage 24, guidé par la langue 25 qui se loge dans la rainure 37 en forme dtarc destinée à eviter un mouvement de rotation à la pièce 22. une partie le long de la lame se loge dans la rainure 26 ce qui permet d'éviter un mouvement de rotation à la lame 12 avec la partie mobile 7, et de diriger le mouvement de translation des deux derniers.--- The piston holder part 22 is assembled with the jacket 23, in the counterbore 24, guided by the tongue 25 which is housed in the groove 37 in the dtarc shape intended to avoid a rotational movement to the part 22. a part the along the blade is housed in the groove 26 which avoids a rotational movement to the blade 12 with the movable part 7, and to direct the translational movement of the last two.

--- Puis on assemble le couvercle 27 avec la chemise 23, à l'aide du filetage 28 de la chemise 23, et du filetage interne 29 du couvercle 27. Ce qui permet d'avoir un contact par serrage du lamage 30 du couvercle 27, avec une partie de la surface 32 de la pièce porte piston 22 et la surface de la cou ronne31 de la chemise 23. Le raccord de la douille filetée33, permet le passage des deux fils électriques et de raccorder la douille polyvalente avec une tige filetée creuse d'un autre mécanisme.--- Then the cover 27 is assembled with the jacket 23, using the thread 28 of the jacket 23, and the internal thread 29 of the cover 27. This makes it possible to have a contact by tightening the counterbore 30 of the cover 27, with a part of the surface 32 of the piston-carrying part 22 and the surface of the neck ron31 of the jacket 23. The connection of the threaded sleeve33 allows the passage of the two electric wires and of connecting the multipurpose sleeve with a rod threaded hollow from another mechanism.

Conformement à la présente invention, l'encastrement des deux culots des lampe électriques à vis ou à baionnette s'effectue comme suit : --- Pour le culot de la lampe à baionnette
On introduit le culot de la lampe à baionnette 34, dans la chemise 23. On passe les deux ergots, dont l'un deux porte le n" 35 du culot 34; le long des deux rainures~36 et 37. On obtient le contact de l'anode (respectivement la cathode) avec la partie mobile 8 du piston 2, qui est la phase Crespectivement le neutre). En même temps le contact de la cathode (respectivement l'anode), avec la partie mobile 7 du piston 1, qui est le neutre (respectivement la phase). Ces deux partie mobiles 7 et 8, des deux pistons 1 et 2, vont se comprimer d'une certaine et même distance.Puis on effectue un angle de rotation, pour permettre aux ergots du culot 34 de se loger dans les deux points de reps s 3 et 38; on lache la lampe. Les deux parties mobiles 7 et 8, vont se decomprimer d'une distance inférieure à celle comprimée, la lampe est maintenue en position d'arrêt. On ferme le circuit électrique, la lampe s'allume. La translation de la partie mobile 7 entraine la translation de la lame 12 qui sont assemblées. Pour déloger le culot de 1a lampe à baïonnette de la douille, il suffit d'inverser le procédé d'encastrement.In accordance with the present invention, the embedding of the two bases of the electric screw or bayonet lamp is carried out as follows: --- For the base of the bayonet lamp
The base of the bayonet lamp 34 is introduced into the jacket 23. The two pins are passed, one of which bears the number 35 of the base 34, along the two grooves ~ 36 and 37. The contact is obtained of the anode (respectively the cathode) with the movable part 8 of the piston 2, which is the phase Crespectively neutral. At the same time the contact of the cathode (respectively the anode), with the movable part 7 of the piston 1 , which is the neutral (respectively the phase). These two moving parts 7 and 8, of the two pistons 1 and 2, will compress by a certain and same distance. Then an angle of rotation is made, to allow the lugs of the base 34 to be housed in the two reference points s 3 and 38; the lamp is released. The two mobile parts 7 and 8 will decompress by a distance less than that compressed, the lamp is held in the stopped position The electrical circuit is closed, the lamp lights up, the translation of the movable part 7 causes the translation of the blade 12 which are assembled. To dislodge the base of the bayonet lamp from the socket, simply reverse the embedding process.

--- Pour le culot de la lampe à vis
Aprés avoir déloger le culot de la lampe à baïonnette de la douill-e polyvalente. On-introduit le culot 39 de la lampe à vis dans la chemise 23, avant que a surface plane du cône du culot 39 qui est l'anode (respectivement la cathode), soit en contact avec la partie mobile 8 du piston 2, qui est la phase (respectivement le neutre). C'est la lame 12 qui sera en contact perpendiculaire sur une partie de la surface cônique du cylindre fileté. On assemble le cylindre fileté du culot 39 avec les trois arcs filetés 40, 41 et 42 de la chemise 23.--- For the screw lamp base
After having dislodged the base of the bayonet lamp from the versatile socket. The base 39 of the screw lamp is introduced into the jacket 23, before the plane surface of the cone of the base 39 which is the anode (respectively the cathode), is in contact with the movable part 8 of the piston 2, which is the phase (respectively neutral). It is the blade 12 which will be in perpendicular contact on a part of the conical surface of the threaded cylinder. The threaded cylinder of the base 39 is assembled with the three threaded arcs 40, 41 and 42 of the jacket 23.

La lame 12 se fait pousser vers l'intérieur et dir iger par la rainure 26. La pénétration de la lame vers l'intérieur (vers la pièce porte piston (broche) 22 ), comprime la partie mobile 7 du piston 1, pour éviter le contact de la surface plane du cône avec la partie mobile 7. La distance disolation électrique entre la surface plane du cône et de la partie mobile 7 du piston 1 est assurée, la lame qui est le neutre (respectivement la phase), est en contact avec une partie de la surface du cylindre fileté qui est la cathode (respectivement l'anode). Puis vient le contact de la surface plane du cône qui est l'anode (respectivement la cathode) avec la partie mobile 8 qui est la phase (respectivement le neutre). L'encastrement se poursuit jusqu'à ce que le piston 2 soit complétement comprimé, ainsi que le piston 1.On ferme le circuit électrique, la lampe s'allume, pour déloger le culot de la lampe à vis de la douille polyvalente, il suffit d'inverser le procédé d' encastrement.-
Selon une variante non illustrée, le raccord de la douille fileté 33 peut être remplacé par un téton de hauteur limité, non fileté. Ce téton creux permettra le passage des deux fils électriques.The blade 12 is pushed inwards and dir iger by the groove 26. The penetration of the blade inwards (towards the part carrying the piston (pin) 22), compresses the mobile part 7 of the piston 1, to avoid the contact of the planar surface of the cone with the movable part 7. The electrical isolation distance between the planar surface of the cone and the movable part 7 of the piston 1 is ensured, the blade which is the neutral (respectively the phase), is in contact with a part of the surface of the threaded cylinder which is the cathode (respectively the anode). Then comes the contact of the flat surface of the cone which is the anode (respectively the cathode) with the movable part 8 which is the phase (respectively the neutral). The installation continues until the piston 2 is completely compressed, as well as the piston 1. We close the electrical circuit, the lamp comes on, to dislodge the lamp base from the multi-purpose socket, it just reverse the embedding process.
According to a variant not illustrated, the connection of the threaded sleeve 33 can be replaced by a stud of limited height, not threaded. This hollow stud will allow the passage of two electric wires.

A titre d'exemple non limitatif, augmentes la longueur de la lame 12-de deux-millimètres pour augmenter la distance d'isolation électrique entre la surface plane du cône du culot de la lampe à vis, avec la partie mobile 7 du piston 1. Cela augmente la longueur des deux pistons et 2, de la chemise 23 et du couvercle 27.  By way of nonlimiting example, increase the length of the blade 12 by two millimeters to increase the distance of electrical insulation between the flat surface of the cone of the base of the screw lamp, with the movable part 7 of the piston 1 This increases the length of the two pistons and 2, of the jacket 23 and of the cover 27.

Selon une deuxième variante non illustrée, le filetage 28 de la chemise 23, peut être prolongé. Afin qu'on puise monter (assembler) la douille polyvalente dans un autre mécanisme; exemple : les baladeuses. According to a second variant not shown, the thread 28 of the jacket 23 can be extended. So that we can mount (assemble) the versatile socket in another mechanism; example: portable lamps.
