Description

Dispositif d'attache ä un mouvement d'horlogerie, de 1'extremite exterieure d'un spinal de balancier Lobjet de la presente invention est un dispositif d'attache, ä un mouvement d'horlo- gerie, de 1'extremite exterieure d'un spinal de balancier, dispositif comprenant une pike ä laquelle est fixee ladite extremite. Device for attaching to a clock movement the outer end of a balance wheel spinal The object of the present invention is a device for attaching to a clock movement the outer end of a balance wheel. a pendulum spinal, device comprising a pike to which said end is fixed.

Ce dispositif est caracterise par 1e fait que 1e mouvement presente, pour cette pike, un logement avec entree laterale, des moyens d'orientation dans 1e logement et ä la piece pour la mise en place exacte de celle-ci, et un organe de fixation solidarisant 1e mouvement et la piece, 1e tout de fagon que cette derniere puisse eire montee et demontee, 1'extremite du spinal restant en prise avec elle. This device is characterized by the fact that the first movement has, for this pike, a housing with side entry, means of orientation in the first housing and to the piece for the exact positioning of the latter, and a fixing member uniting the movement and the part, so that the latter can be assembled and disassembled, the end of the spinal cord remaining in engagement with it.

Le dessin ci-annexe represente, ä titre d'exemple, une forme d'execution de 1'objet de la presente invention. La fig. 1 en est une vue generale en plan. Les fig. 2 et 3 montrent un ddtail en plan et en elevation ; et les fig. 4, 5 et 6 montrent un autre detail en plan, en elevation et en coupe suivant VI-VI de la fig. 4. The attached drawing represents, by way of example, one embodiment of the object of the present invention. fig. 1 is a general plan view. Figs. 2 and 3 show a detail in plan and in elevation; and Figs. 4, 5 and 6 show another detail in plan, in elevation and in section along VI-VI of fig. 4.

En fig. 1, 1 represente la platine dune montre, 2 1e coq de celle-ci, 3 son balancier et 4 1e spinal. In fig. 1, 1 represents the plate of a watch, 2 the first cock of this one, 3 its balance wheel and 4 the first spinal.

L'extremite exterieure 5 de celui-ci passe dans un dispositif represente aux fig. 4, 5 et 6. Celui-ci comprend une piece constituant un bäti 6 dans lequel peut tourner sur lui- meme un cylindre 7 portant un galet 8 et un disque de commande 9. 10 est une brauche e1astique decoupee Jans 1e bäti 6, parallele ä faxe de rotation du cylindre 7 et se terminant en regard du galet 8 par une calotte spheri-. que 11 ; 1'extremite exterieure du ressort spi ral est serree entre ce galet et cette calotte. The outer end 5 thereof passes through a device shown in FIGS. 4, 5 and 6. This comprises a part constituting a frame 6 in which can rotate on itself a cylinder 7 carrying a roller 8 and a control disc 9. 10 is an elastic brauche cut Jans the first frame 6, parallel ä faxe of rotation of the cylinder 7 and ending opposite the roller 8 by a spheri- cap. than 11; the outer end of the spiral spring is clamped between this roller and this cap.

Le bäti 6 est porte par la raquette 12 et monte dans un logement 13 de celle-ci avec entree laterale 14 (voir fig. 2 et 3). La paroi interieure de ce logement presente un angle diedre 15 egal ä 1'angle diedre 16 pratique sur 1e bäti 6. Ce dernier s'engage dans 1e loge- ment 13 par 1'ouverture 14 et il est oriente en position exacte, dans ce logement, par les die- dres 15 et 16 venant en prise. La vis 17, ap- puyant sur lui ä Poppose des angles diedres, permet de 1e fixer dans cette position. The frame 6 is carried by the racket 12 and mounted in a housing 13 of the latter with side entry 14 (see FIGS. 2 and 3). The interior wall of this housing has a dihedral angle 15 equal to the dihedral angle 16 practiced on the first frame 6. The latter engages in the first housing 13 by the opening 14 and it is oriented in the exact position, in this housing, by the corners 15 and 16 coming into engagement. The screw 17, pressing on it opposite dihedral angles, allows it to be fixed in this position.

Lorsqu'on tourne 1e disque 9 dans un sens ou dans 1'autre, an entraine 1'extremitd exte- rieure du spinal, ce qui permet de raccourcir ou d'allonger la longueur active du spinal. Lors d'un demontage, gräce ä 1'entree laterale 14, il suffit de devisser la vis 17RTI ID="0001.0269" WI="8" HE="4" LX="1560" LY="2141"> pour pouvoir sortir 1e bäti 6 du logement 13, 1'extremite exterieure du spinal restant engagee entre 1e galet 8 et la calotte 11 ; 1e montage peut, de meme, se faire, 1e spiral pince entre 1e galet et la calotte. When the disc 9 is rotated in either direction, an entrains the outer extremity of the spinal, which makes it possible to shorten or lengthen the active length of the spinal. During disassembly, thanks to the side entrance 14, it suffices to unscrew the screw 17RTI ID="0001.0269" WI="8" HE="4" LX="1560" LY="2141"> to be able to exit the first frame 6 of the housing 13, the outer end of the spinal remaining engaged between the first roller 8 and the cap 11; 1st assembly can likewise be done with the 1st hairspring pinched between the 1st roller and the cap.

Le logement 13 et son entree 14 pour- raient eire pratiques dans une autre partie du mouvement que la raquette, par exemple di- rectement dans le coq. Dans ce cas, la mise au repere pourrait s'effectuer en tournant la virole de balancier. The housing 13 and its inlet 14 could be used in another part of the movement than the racket, for example directly in the cock. In this case, the positioning could be done by turning the balance ring.

Claims

CLAIM Device for attaching, to a clockwork movement, the outer end of a balance spring, device comprising a pike to which said end is fixed, characterized in that the movement has, for this pike, a housing with side entry, means of orientation in the first housing and at the pike for the exact positioning of the latter, and a fixing member securing the movement and the piece, the first all fa@on that the latter can be mounted and dismounted, the end of the hairspring remaining in engagement with it. SUB-CLAIMS 1. Device according to claim, characterized by the fact that the aforementioned orientation means comprise a dihedral angle presented by the interior wall of the housing and at least one plane applied against one of the faces of the dihedral and presented by the aforesaid pike.

2. Device according to sub-claim 1, characterized in that the fixing member is a screw which is screwed into the racket and presses on said piece opposite the dihedral angle.
