Description

Raquetterie pour piece d'horlogerie Racquetry for timepieces

La pr6sente Invention a pour objet une raquetterie pour piece d'hodogerie ä balancier et spinal. The subject of the present invention is a rack for a pendulum and spinal clockwork piece.

Cette raquetterie est caract6ris6e par 1e fait que 1e spiral est maintenu en place par une plaquette 61astique 1e serrant contre une port6e en arc de cercle de son Support, cette plaquette 6tant fix & audit support en deux points, 1e tout agence de maniere que lorsque ladite plaquette est desserr6e, en 1'un au moins de ces deux points, alle tende 61astiquement ä se redresser, liberant ainsi 1e spinal. This racking is characterized by the fact that the balance spring is held in place by a 61astic plate clamping it against an arcuate bearing surface of its support, this plate being fixed to said support at two points, the whole arranged in such a way that when said platelet is loosened, in at least one of these two points, it tends 61astically to straighten, thus releasing the spinal.

Le dessin annex6 represente, ä titre d'exemple, deux foirmes d'execution de 1'objet de 1'invention. La fig. 1 est une vue en plan dune Premiere forme d'ex & ution dune raquetterie de pike d'horlogerie. The appended drawing shows, by way of example, two forms of execution of the object of the invention. fig. 1 is a plan view of a first form of execution of a clock pike racket.

La fig. 2 est une coupe suivant la ligne IILi de la fig. 1. fig. 2 is a section along the line IIIi of FIG. 1.

La fig. 3 en est une vue de Profil. fig. 3 is a profile view.

La fig. 4 est une vue en plan dune Partie dune deuxieme forme d'execution de raque@tterie de pike d'horlogerie, avec coupe partielle, et la fig. 5 en est une vue de Profil. fig. 4 is a plan view of a Part of a second form of execution of raque@tterie of clockwork pike, with partial section, and FIG. 5 is a profile view.

La raquetterie repr6sentee dans les fig. 1 ä 3 comprend un Support de spinal 1 mont6 rotativement autour dun coqueret 2 Porte par 1e coq 3. Le balancier n'a pas 6t6 represent6, non plus que 1e spiraZ, hormis 1'extr6mit6 de sa spire ext6rieure, design6e par 4. Cette extremit6 du spinal est Pressee par une plaquette 61astique 5 contre une portee en arc de cercle 6 que presente une orsille 1a du support 1. Cette plaquette est maintenue en place par deux vis 7 et 8 prenant dans 1'oreille la du sup- The racket represented in figs. 1 to 3 comprises a Spinal support 1 mounted rotatably around a cup 2 Carried by the cock 3. The pendulum has not been represented, nor has the spiral Z, except for the end of its outer spiral, designated by 4. This extremity of the spinal is pressed by a elastic plate 5 against a bearing surface in the form of a circular arc 6 presented by an orsilla 1a of the support 1. This plate is held in place by two screws 7 and 8 taking the ear of the support in the ear.

port 1. Elle pr6sente deux oreilles 5a et 5b situees au droit des vis 7 et 8, pressant 1e spiral contre la portee 6. Lorsque les vis sont serr6es, la plaquette 6pouse la forme en arc de cercle de la port6e 6 et, lorsque ces vis sont desserr6es, eile tend 61astiquement ä se redresser, ne restant en contact avec la portee 6 qu'en son milieu, lib6rant ainsi 1e spinal. port 1. It has two lugs 5a and 5b located in line with screws 7 and 8, pressing the hairspring against bearing 6. When the screws are tightened, the plate takes on the arcuate shape of bearing 6 and, when these screws are loosened, it tends to straighten up 61astically, remaining in contact with the bearing 6 only in its middle, thus releasing the spinal.

La raquette, design & par 9, est tres mmce ; edle est mont6e rotativement Sur 1e porte-spiral 1 et pr6sente une oreille d6coup6e 9a, termin6e par des langnettes 9b et 9c repli6es ä angle droit. Ces langnettes constituent les butees de r6glage de la longueur active du spinal. The racket, design & par 9, is very mmce; edle is rotatably mounted on the hairspring holder 1 and has a cut-out lug 9a, terminated by tongues 9b and 9c bent at right angles. These tabs constitute the adjustment stops for the active length of the spinal.

En faisant tourner 1e porte-spiral 1 autour du coqueret 2, an effectue la mise au repke du balancier, la raquette 9 6tant entrain & , alors qu'en d6plagant la raquette 9, an regle la longueur active du spinal, sann entrainer 1e pozte-spiral 1. By rotating the 1st hairspring holder 1 around the shell 2, an performs the repositioning of the balance wheel, the racket 9 being driven & , while by moving the racket 9, an adjusts the active length of the spinal, without driving the 1st lever - hairspring 1.

Dans la forme d'ex6cution des fig. 4 et 5, 1e spinal 10 est press6 contre une port6e en arc de cercle 12 du porte-spiral 13 par une plaquette 14 maintenue en place par deux vis 15 et 16 prenant dans une oreille 13a du porte-,spiral. Au droit de la vis 16, 1a plaquette 14 est cintree en 14a de maniere ä prendre appui sur 1e spiral par deux aretes. La vis 16 traverse une ouverture allong6e 17 de la plaquette 14, ce qui permet, lorsqu'elle est dessern & , de soulever la plaquette et de la faire tourner autour de la vis 15 pour 1'amener dann la Position repr6sent6e en traits mixtes dans la fig. 5, Position Jans laquelle 1e spinal est lib6re. In the form of execution of FIGS. 4 and 5, the first spinal 10 is pressed against a port6e arcuate 12 of the hairspring holder 13 by a plate 14 held in place by two screws 15 and 16 taking in an ear 13a of the holder, hairspring. In line with screw 16, plate 14 is bent at 14a so as to rest on the hairspring by two edges. The screw 16 passes through an elongated opening 17 of the wafer 14, which makes it possible, when it is loosened &, to lift the wafer and to make it turn around the screw 15 to bring it into the position represented in phantom in fig. 5, Position in which the spinal is free.

Une plaquette 18 est serr6e par la vis 15, qui prAente ä cet effet une port6e 15a, contre 1e po@tespiral 13. Cette plaquette situ6e sous la plaquette 14 pr6sente une langnette 18a recourb6e deux fois, A plate 18 is tightened by the screw 15, which for this purpose presents a bearing 15a, against the first spiral 13. This plate located under the plate 14 presents a tongue 18a curved twice,

formant crochet pour 1e spiral. Elle determine ainsi la Position en hauteur du spinal. En devissant la vis 15, an peut däplacer la plaquette 18 et modifier ainsi la hauteur du crochet 18a et par consequent du spiral. forming a hook for the first hairspring. It thus determines the height position of the spine. By unscrewing the screw 15, an can move the plate 18 and thus modify the height of the hook 18a and consequently of the hairspring.

Cette plaquetroe 18 et 1e crochet 18a pourront etre remplaces par un rebord 13b du porte-spiral; representä en traits mixtes dans les fig. 4 et 5, contre lequel prendra appui le spiral, ce qui d6terminera sa Position en hautaur. This plaquetroe 18 and the first hook 18a can be replaced by a rim 13b of the hairspring holder; represented in phantom in figs. 4 and 5, against which the hairspring will rest, which will determine its position at the height.

La raquette, designäe par 19, est montee rotativement Sur 1e porte-spiral 13. The racket, designated by 19, is rotatably mounted on the 1st hairspring holder 13.

Claims

CLAIM Raquetterie for clockwork piece with balance wheel and hairspring, characterized by the fact that the hairspring is held in place by an elastic plate pressing it against an arcuate bearing surface of its Support, this plate being fixed to said Support at two points, the whole arranged so that when said plate is loosened at at least one of its two points, it elastically tends to straighten, thus disengaging the hairspring. SUB-CLAIMS 1. Racket according to claim, characterized by the fact that said wafer is fixed to the hairspring support by screws which apply it against said bearing surface so that it matches its shape.

2. Racket according to claim and sub-claim 1, characterized in that said wafer has two lugs each located in line with one of the two fixing screws, each pressing the hairspring against said arcuate bearing surface of the Support.

3. Racket according to claim, characterized by the fact that said wafer is fixed to the spiral support by a peg, on the one hand, and by a screw, on the other hand, crossing an elongated opening of the wafer so that the screw being loosened, the pad can be rotated around said peg.

4. Racket according to claim, characterized by the fact that, at at least one of its two fixing points, the pad has a curved part through which a screw engages in said support.

5. Raquetterie according to the claim, characterized by the fastness that said bearing in an arc of a circle of the hairspring support presents, on its lower edge, a ledge against which the hairspring is pressed, which determines its position in height.
