Le @s@ocle peut comprendre un supp ort pou- vant servir,6galement de ref lecteur auquel an fixe la lampe-tube par 1'intermediaire de deux prises, dant l'une au moims peut etre amovi- ble. Ces prises peuvent etre munies dune ou plusicurs pinces de contact destinee:s ä ,s:aisir la ou fes broches portees@ par chaque oulot de la lampe-tube. En deplacaut une pris@e autour de. ,sou axe de rotatian, o:n peut ntroduire les broches d'un culot daas les, pinces de contact de la prse oppos,ee, pui;s les braches de 1'autre culot daus les pinces de la brocke d6placee, en laissant celle--ci reprendre sa po:sition normale. Pour,degager la lampe, an fait 1'operation in verse. Un orga(ne de rappel elastique ramene @chaque prise amovible dans sa position nor male, as!surant ainsi la fixation de la la.mpe et empächant 1e degagement acci-dentel .de celle-ci, par exemple saus 1'effet de trepidiatio#ns. Le cou- ramt öleetrique neoessaire au fonctionnement de la lampe-tube arrive aux prises par des Iames mbtalliques portant chacune une pince de contact. Ces pinces transmettent 1e courant aux broches des culots de la lampe-aulve qui le,conduisent ä 1'interieur de la lampe. The base can include a support that can also be used as a reference reader to which the tube lamp is fixed by means of two sockets, at least one of which can be removable. These sockets can be provided with one or more contact clamps intended: s ä, s: seize the pin or fes ported @ by each oulot of the lamp-tube. By moving a socket around. , under axis of rotation, o: n can introduce the pins of a base in the, contact clamps of the opposite prse, ee, then the braches of the other base in the clamps of the displaced bracket, leaving it resume its normal po: sition. To release the lamp, do the reverse operation. An organ (not of elastic recall brings back @ each removable plug in its normal position, assuring thus the fixing of the la.mpe and preventing the first accidental release .of this one, for example without the effect of trepidation The electric current necessary for the operation of the lamp-tube arrives at the sockets by metal blades each carrying a contact clamp These clamps transmit the current to the pins of the bases of the lamp-allow which lead it to 1 interior of the lamp.

L'une de oes prises peut etre fixe et 1'autre amovible ou bien les deux sont amovIbles, La lampe@tube 16, dont les deux culots sont munis chazun de deux bro- ches 17, est maintenue en, place par la p6ne- tration des broohes dann les o#rifieesi 34 des pris-es 18 et 19. Las braches sont alimenMes en eourant e1eetrique par les pinces d'e con.- tact 33 disposees@ au fand des, orifices 34; ces pinces 33, lo,gees dams les deux trous 32, sant reliees par 1'intermediaire de lam:es m6talli- ques 22, tee-rminees par des extremites repliees insenäes dans des rainures 39, et de vis de con- nexion 40 aux fils ,co@udtucteurs de courant. Ges fils ne sont pas represent s Jans le dessin, mais peuvent facilem.ent eire places derriere 1e Support 15. In particular relates to figures. of -drawing amu-exe, the 1st shield includes: Two bipolar sockets 18 and 19 mounted on a support 15. One of these sockets can be fixed and the other removable or both are removable, The lamp@ tube 16, the two ends of which are each provided with two pins 17, is held in place by the penetration of the pins into the holes 34 of the sockets 18 and 19. The pins are supplied with electrical current by the clamps of e con.- tact 33 disposed @ the fand of, orifices 34; these clamps 33, lo, gees in the two holes 32, are connected by the intermediary of metal blades 22, terminated by folded ends inserted in grooves 39, and connection screws 40 to the wires, current conductors. The wires are not shown in the drawing, but can easily be placed behind Support 15.

Il est avantageux de prevoir une cons- truction identique pour les: deux prises 18 et 19. Elles sont fonnees. chacune par un bloss en matnere plastique isolante 20 presentaut deux cavites 21 dans lesquelles sont logees deux lames metalliques 22. Une cloisan 23 se püre les deux cavit6s 21. Lette cloison se sub- divise en deux parois 24 pour former la cham- bre 25. Lette chambre esl limitee vers 1e haut par uue paroi percee d'un tro.u. Une vis 26, dont la tete 31 repose Sur une plaquette 30, penetre dann ce treu pour venir ä 1'interieur de la,chambre 25 o@ü elle traverse s@ucces isive- ment un treu 44 dune lauguette 43 dune Plaque de fixation 42 -et un ressort 27. Sur 1'extr6mite filetee 29 de rette vis 26 est monte un ecrou 28 permettant & comprimer 1e res- sort 27 contre la 1'anguette 43 qui est ainsi applquee contre la paroi limitant vers 1e haut la chamibre 25. Ce montage permot une liaison e1#a & tique des.prises bipolaires 18 ou 19 et de la Plaque de fixation 42. La ro- tation - de la Plaque de fixation 42 par rap- Port ä la Prise est a@ssuree par la Penetration de la Plaque de fixation 42 dann une entaille 41 disposee en travers ,du bloc de mauere plastique 20. La Plaque de fixation 42 poste, en outre, deux becs 47 ernpechant tout d6p1a- cement lateral de la Plaque 42 par rapport ä la Prise. La Plaque 42 est aussi maintenue en place lo@ngitudinalement par une goupille 45 travereant un treu 46 de la Plaque 42"cette goupille 45 kaut noyee dans 1e bloss ds ma- ti6re plastique 20. Le treu 44 de la languette 43 de .la Plaque de fixation 42 est dimen- sionue de fagon ä permettre 1e mouvement de celle-@ci autour de faxe de rotation forme par la 1 bbne -de contact de 1'arete de la Plaque de fixation 42 avec 1e fand 48 de 1'entaille 41. Des trous 49de 1a Plaque de fixat%on 42 ser- vent ä fixer rigidement -celle-ai sur 1e support 15 au moy'en,des vis 50 et ecrous 51. It is advantageous to provide an identical construction for the two sockets 18 and 19. They are formed. each by a bloss in insulating plastic material 20 has two cavities 21 in which are housed two metal blades 22. A partition 23 purifies the two cavities 21. This partition is divided into two walls 24 to form the chamber 25. Lette room is limited upwards by a wall uue pierced with a hole. A screw 26, the head 31 of which rests on a plate 30, penetrates into this hole to come inside the chamber 25 where it passes successfully through a hole 44 of a tongue 43 of a fixing plate 42 and a spring 27. On the threaded end 29 of the screw 26 is mounted a nut 28 enabling the spring 27 to be compressed against the tongue 43 which is thus applied against the wall limiting the chamber 25 upwards. This assembly allows an elastic connection of the bipolar sockets 18 or 19 and the fixing plate 42. The rotation of the fixing plate 42 with respect to the socket is ensured by the Penetration of the Fixing Plate 42 in a notch 41 arranged across the block of plastic mauer 20. The Fixing Plate 42 also posts two lugs 47 preventing any lateral displacement of the Plate 42 with respect to the Socket. . Plate 42 is also held in place longitudinally by a pin 45 passing through a hole 46 of Plate 42, this pin 45 kaut embedded in the plastic material 20. The hole 44 of the tongue 43 of the Plate mounting plate 42 is sized to allow movement thereof around the axis of rotation formed by the contact rod of the edge of the mounting plate 42 with the fand 48 of the notch 41 Holes 49 of the Fixing Plate 42 are used to rigidly fix it to the support 15 by means of screws 50 and nuts 51.

0n peut aussi reäliser un montage avec rappel elastique des prises 18 ou 19 eur 1e Support 15, en: fixant rigidement la Plaque de fixation 42 au bloc de matiere plastique 20 au moyem d'nne vie 55 et d'un ecrou 56 tra- versamt le treu de la paroi superieure de la chambre 25 @et 1e treu 44 de la languette 43 ,de la plaque de fixation 42; cel:le-ci,est mon- tee elaastiquemient Sur 1e suppart 15 au moyen de deux vis- 57, de deux rondelles 59, de deux ressio@rts 58, de deux rondelle:s 60 et de deux eorous 61. La feg. 7 pnesente,ce genre de mon- tage, la vis 57 traversant premierement les trous 62 du Support 15, puis les trous 49 de la Plaque de fixation 42, ce qui permet la rota- tion de la plaque de fixation 42 autourde 1'arete de celle--ci la plus elaiguee de la face 35 du bloc 20. La fig. 8 p@resente une variante de ce mo,d,e,de montage, les vis: traversant premi6re- ment les trous 49 de la. Plaque de fixation 42, puls les trous 62 du Support 15, ce qui per- met la rotation de la Plaque de fixation autoirr du bord: 63 du treu ,de logement de la priee Jans. 1e Support 15 voisin de 1a face 35 du bloc 20. Damas 1e ews) de la fig. 8, la Pla- que de fixation 42 est montee contre la face .du ,Support 15 qui est en regard de la lampe 16, tandie que, -d'ans 1e ras d@e la fig. 7, la plaque de fixation 42 est montée sur la face du support 15 opposée à la lampe 16. It is also possible to make an assembly with elastic return of the sockets 18 or 19 to the support 15, by: rigidly fixing the fixing plate 42 to the block of plastic material 20 by means of a screw 55 and a nut 56 passing through the hole in the upper wall of the chamber 25 and the first hole 44 in the tongue 43 of the fixing plate 42; cel: the latter, is mounted elaastiquemient On the first suppart 15 by means of two screws 57, two washers 59, two ressio@rts 58, two washers: s 60 and two eorous 61. The feg. 7 shows this type of assembly, the screw 57 first passing through the holes 62 of the support 15, then the holes 49 of the fixing plate 42, which allows the rotation of the fixing plate 42 around the edge. of this one the most elaiguee of the face 35 of the block 20. FIG. 8 p @ resente a variant of this mo, d, e, mounting, the screws: first crossing the holes 49 of the. Fixing plate 42, pulsing the holes 62 of the Support 15, which allows the rotation of the Fixing plate around the edge: 63 of the hole, of housing of the prayer Jans. 1st Support 15 adjacent to face 35 of block 20. Damascus 1st ews) of FIG. 8, the fixing plate 42 is mounted against the face of the support 15 which faces the lamp 16, while, -in the first level of FIG. 7, the fixing plate 42 is mounted on the face of the support 15 opposite the lamp 16.

Afin. de diminuer l'amplitude nécessaire du mouvement ,de rotation -de la prise amovi ble ou des prises amovibles, selon le genre -de montage adopté (une prise fixe et une prise mobile ou deux prises. mobiles), .on pratique dans le bloc de matière plastique 20 deux rai nures 36 dont la largeur est légèrement supé rieure au diamètre de la broche et s'évase vers la base 37 de la prise, cette rainure de vant permettre lie passage des broches des eu- lots 17 depuis la base 37 de chaque prise vers les orifices 34, dans lesquels les broches vien nent s'engager pour atteindre les pinces de contact 33 comme représenté dans les fig. 2 et 6 du dessin. La profondeur des rainures 36 diminue graduellement de la base 37 de la prise vers l'oridice 34, de façon que, par con tact -du bout de la broche du culot 17 sur les fondis 38 des rainures 36, la prise soit éloignée du culot 17 lorsqu'on monte la lampe 16. Ce montage est exécuté eo@mme suit (voir fig. 1 du dessin): En déplaçant une prise au moins, par exemple la prise 19, dans la position in clinée montrée à la fig. 1, on peut introduire les broches d'un -culot dans la prise opposée 18, puis faire glisser les deux autres broches contre les fonds 38 -dies rainures 36 de la prise 19 jusqu'à ce que les broches arrivent en face des ,orifices 34, dans, lesquels elles pénètrent grâce à la tendance qu'a la prise 19 à revenir dans sa position normale, dessinée en poin tillés, sous l'effet du rappel élastique décrit plus haut. Lorsque les broches des culots 17 ont pénétré dan@si des orifices 34 et ont atteint les pinces de contact 33, lia lampe est sup portée par les,orifices, 34 et elle ne peut pas se détacher sous l'effet de trépidations, éven tuelles. In order to. to reduce the necessary amplitude of the movement, of rotation -of the removable socket or the removable sockets, depending on the type -of assembly adopted (one fixed socket and one mobile socket or two mobile sockets), .one practices in the block of plastic material 20 two grooves 36 whose width is slightly greater than the diameter of the pin and flares out towards the base 37 of the socket, this front groove allowing the pins of the sockets 17 to pass from the base 37 from each socket to the orifices 34, in which the pins come to engage to reach the contact clamps 33 as shown in FIGS. 2 and 6 of the drawing. The depth of the grooves 36 gradually decreases from the base 37 of the socket towards the orifice 34, so that, by contact -of the end of the pin of the base 17 on the bottoms 38 of the grooves 36, the socket is moved away from the base. 17 when mounting the lamp 16. This assembly is executed as follows (see FIG. 1 of the drawing): By moving at least one socket, for example socket 19, into the tilted position shown in FIG. 1, one can introduce the pins of a -base in the opposite socket 18, then slide the other two pins against the bottoms 38 -dies grooves 36 of the socket 19 until the pins arrive opposite the holes 34, in which they penetrate thanks to the tendency of the socket 19 to return to its normal position, drawn in dotted lines, under the effect of the elastic return described above. When the pins of the sockets 17 have entered dan @ if holes 34 and have reached the contact clamps 33, the lamp is supported by the holes 34 and it cannot come off under the effect of tremors, possible .

La face du bloc de matière plastique 20, opposée à la face 35 adjacente au culot die la lampe, est munie d'un couvercle 52 fixé au bloc 20 par des vis 54 introduites dans des trous taraudés 53 prévus dans ce bloc (fig. 4). Ce couvercle protège et maintient les lames métalliques 22, fermant aussi la chambre 25, comme le montrent les fig. 3, 5 et 6. The face of the block of plastic material 20, opposite the face 35 adjacent to the base of the lamp, is provided with a cover 52 fixed to the block 20 by screws 54 introduced into tapped holes 53 provided in this block (FIG. 4 ). This cover protects and holds the metal blades 22, also closing the chamber 25, as shown in Figs. 3, 5 and 6.
