Description

La présente invention est relative à un porte-monture de lunettes pour une machine à reproduire, dite copieur, apte à tailler un gabarit ou une lentille ophtalmique sous la commande d'un dispositif comportant un palpeur qui reconnait le contour intérieur des cercles d'une monture de lunettes.The present invention relates to a spectacle frame holder for a reproducing machine, known as a copier, capable of trimming a template or an ophthalmic lens under the control of a device comprising a feeler which recognizes the inner contour of the circles of a eyeglass frame.

On sait que le positionnement d'une monture sur la machine à copier doit être extrêmement précis afin que le gabarit ou le verre ophtalmique soit parfaitement centré par rapport au cercle de la monture.We know that the positioning of a frame on the copying machine must be extremely precise so that the template or the ophthalmic lens is perfectly centered relative to the circle of the frame.

On connait déjà différents dispositifs _ par exemple celui décrit dans FR-E-89350 _ pour la mise en place contrôlée d'une monture de lunettes sur une machine à reproduire. Les plus répandus de ces dispositifs comportent une plaque de base destinée à soutenir la monture et sur laquelle deux réglettes parallèles sont montées mobiles l'une par rapport à l'autre en se rapprochant et en s'éloignant, et des moyens pour immobiliser ces réglettes dans une position choisie. Une monture est disposée et serrée entre les réglettes qui sont alors immobilisées et l'ensemble est alors placé sur la machine dans une position fixée par des moyens complémentaires prévus sur ladite plaque et la machine.We already know different devices _ for example that described in FR-E-89350 _ for the controlled placement of a spectacle frame on a reproducing machine. The most common of these devices include a base plate intended to support the frame and on which two parallel strips are mounted movable relative to each other by moving towards and away from them, and means for immobilizing these strips in a chosen position. A mount is arranged and clamped between the strips which are then immobilized and the assembly is then placed on the machine in a position fixed by complementary means provided on said plate and the machine.

Dans un tel dispositif, la monture doit être exactement immobilisée entre les réglettes, sans jeu, mais sans déformation, et les systèmes connus jusqu'à présent ne sont pas satisfaisants à cet égard.In such a device, the frame must be exactly immobilized between the strips, without play, but without deformation, and the systems known hitherto are not satisfactory in this regard.

En effet, avec un système de blocage par serrage mécanique des réglettes, lorsque celles-ci ont été amenées en contact avec la monture, un déplacement risque toujours de se produire, introduisant un jeu nuisible de la monture entre les réglettes, et par suite un défaut de précision.In fact, with a locking system by mechanical tightening of the strips, when these have been brought into contact with the frame, a displacement is always likely to occur, introducing a harmful play of the frame between the strips, and consequently a lack of precision.

Dans un autre système connu les réglettes sont sollicitées l'une vers l'autre par des moyens élastiques, c'est-à-dire un ressort, dont le degré de tension est fonction de la dimension de la monture: si la force du ressort peut assurer un serrage à peu près satisfaisant avec des montures de dimensions moyennes, ce serrage peut être insuffisant avec une petite monture - laissant ainsi subsister un jeu _ ou peut être trop fort avec une grande monture _ risquant de la déformer.In another known system, the strips are biased towards each other by elastic means, that is to say a spring, the degree of tension of which depends on the size of the frame: if the force of the spring can provide an almost satisfactory tightening with midsize frames, this tightening can be insufficient with a small frame - thus leaving a play _ or may be too strong with a large frame _ risking deforming it.

L'invention a pour but de remédier à ces inconvénients en fournissant un porte-monture de lunettes pour machine à copier comportant un système d'immobilisation perfectionné des réglettes.The object of the invention is to remedy these drawbacks by providing a spectacle frame holder for a copying machine comprising an improved immobilization system for crimps.

Elle a pour objet à cet effet un porte-monture de lunettes pour machine à reproduire du type comportant une plaque de base, deux réglettes parallèles montées coulissantes sur ladite plaque de façon à se rapprocher ou à s'éloigner l'une de l'autre, et des moyens de centrage de la monture entre lesdites réglettes, caractérisé en ce que les réglettes sont fixées respectivement sur les brins parallèles opposés d'un câble formant une boucle autour de deux poulies espacées, l'une desdites poulies constituant un organe d'entraînement du câble et comportant des moyens de freinage.It has for this purpose a spectacle frame holder for a reproducing machine of the type comprising a base plate, two parallel strips slidably mounted on said plate so as to approach or move away from each other , and means for centering the frame between said strips, characterized in that the strips are fixed respectively on the opposite parallel strands of a cable forming a loop around two spaced pulleys, one of said pulleys constituting a member of cable drive and comprising braking means.

Suivant une autre caractéristique de l'invention, lesdits moyens de freinage sont réglables et comprennent de préférence un organe élastique sollicitant ladite poulie axialement en contact avec un organe de friction.According to another characteristic of the invention, said braking means are adjustable and preferably comprises an elastic member urging said pulley axially in contact with a friction member.

La description qui va suivre, en regard des dessins annexés à titre d'exemples non limitatifs, permettra de bien comprendre comment la présente invention peut être mise en pratique.

  • La figure 2 en est une vue en bout montrant le système de liaison et d'entraînement des réglettes.
  • La figure 3 est une vue partielle à plus grande échelle montrant la poulie formant organe d'entraînement et ses moyens de freinage, certaines parties étant représentées en coupe.
  • La figure 4 est une vue, analogue à celle de la figure 3, d'une variante comportant un moteur d'entraînement.
The following description, with reference to the accompanying drawings by way of nonlimiting examples, will make it possible to understand clearly how the present invention can be put into practice.
  • Figure 1 is a plan view of a spectacle frame holder according to the invention.
  • Figure 2 is an end view showing the connecting and driving system of the strips.
  • Figure 3 is a partial view on a larger scale showing the pulley forming the drive member and its braking means, some parts being shown in section.
  • Figure 4 is a view, similar to that of Figure 3, of a variant comprising a drive motor.

En se référant tout d'abord à la figure 1, le porte-monture suivant l'invention comprend, comme connu en soi, une plaque de base 1 comportant quatre supports verticaux 2, 3, 4, 5 disposés aux angles d'un rectangle. Deux barres parallèles 6, 7 relient entre eux les supports 2, 4 et les supports 3, 5 respectivement, sur les largeurs du rectangle, les barres 6 et 7 étant fixées sur leurs supports respectifs à des hauteurs différentes dans un plan vertical perpendiculairement à la plaque 1, comme représenté à la figure 2.Referring first to Figure 1, the frame holder according to the invention comprises, as known per se, a base plate 1 having four vertical supports 2, 3, 4, 5 arranged at the corners of a rectangle . Two parallel bars 6, 7 connect the supports 2, 4 and the supports 3, 5 respectively, over the widths of the rectangle, the bars 6 and 7 being fixed on their respective supports at different heights in a vertical plane perpendicular to the plate 1, as shown in Figure 2.

Une première réglette 8 est montée coulissante sur les barres 7 entre les supports 2, 3 et 4, 5, et une seconde réglette 9 est montée coulissante sur les barres 6.A first strip 8 is slidably mounted on the bars 7 between the supports 2, 3 and 4, 5, and a second strip 9 is slidably mounted on the bars 6.

Pour assurer un coulissement doux des réglettes 8, 9 sur les barres 6, 7, chaque réglette peut comporter un bossage tubulaire 10, 11 respectivement, entourant l'une des barres 6, 7, et formant butée pour la réglette opposée.To ensure smooth sliding of the strips 8, 9 on the bars 6, 7, each strip may include a tubular boss 10, 11 respectively, surrounding one of the bars 6, 7, and forming a stop for the opposite strip.

Suivant l'invention, une première poulie 12 est montée librement rotative sur le support 2 au moyen d'un axe 13, une seconde poulie 14 est montée rotative sur le support 4 opposé au support 2, au moyen d'un axe 15, et un câble 16 relie les poulies 12, 14 et les réglettes 8, 9, de la façon suivante: une première extrémité du câble 16 est fixée sur un doigt 17 solidaire de la réglette 9, le câble 16 passant ensuite autour de la poulie 14 sur laquelle il est fixé par une vis 18, puis s'étend jusqu'à la réglette 8 sur laquelle il est fixé par une vis 19, passe ensuite autour de la poulie 12 pour revenir au doigt 17 auquel son autre extrémité est reliée par l'intermédiaire d'un ressort 20 dont la seule fonction est d'assurer une tension constante du câble.According to the invention, a first pulley 12 is freely rotatably mounted on the support 2 by means of an axis 13, a second pulley 14 is rotatably mounted on the support 4 opposite the support 2, by means of an axis 15, and a cable 16 connects the pulleys 12, 14 and the strips 8, 9, as follows: a first end of the cable 16 is fixed to a finger 17 secured to the strip 9, the cable 16 then passing around the pulley 14 on which it is fixed by a screw 18, then extends to the strip 8 on which it is fixed by a screw 19, then passes around the pulley 12 to return to the finger 17 to which its other end is connected by the intermediate of a spring 20 whose sole function is to ensure a constant tension of the cable.

Suivant une caractéristique de l'invention, l'axe 15 de la poulie 14 est monté fixe dans le support 4 et la poulie 14 est constituée par un cylindre rotatif autour dudit axe et formant un bouton de commande (figure 3).According to a characteristic of the invention, the axis 15 of the pulley 14 is fixedly mounted in the support 4 and the pulley 14 is constituted by a rotary cylinder around said axis and forming a control button (Figure 3).

Une rondelle de Nylon 21 est disposée entre le support 4 et l'extrémité adjacente du cylindre 14. Ce dernier comporte à son extrémité opposée un contre-alésage 22 dans lequel s'étend l'extrémité de l'axe fixe 15, qui est filetée.A nylon washer 21 is disposed between the support 4 and the adjacent end of the cylinder 14. The latter has at its opposite end a counterbore 22 in which extends the end of the fixed axis 15, which is threaded .

Un ressort 23 du type Belleville est disposé dans le contre-alésage 22 autour de l'axe 15 et est maintenu sous compression par un écrou 24.A Belleville-type spring 23 is placed in the counterbore 22 around the axis 15 and is kept under compression by a nut 24.

Grâce à cet agencement, lorsque le cylindre constituant la poulie 14 est entraîné manuellement en rotation à l'encontre du freinage assuré par le serrage de la rondelle 21 entre la poulie 14 et le support 4, le câble 16 entraîne les réglettes 8 et 9 l'une vers l'autre ou en s'éloignant l'une de l'autre suivant le sens de rotation.Thanks to this arrangement, when the cylinder constituting the pulley 14 is manually rotated against the braking provided by the tightening of the washer 21 between the pulley 14 and the support 4, the cable 16 drives the strips 8 and 9 towards each other or in moving away from each other in the direction of rotation.

Cette action de freinage est réglée au moyen de l'écrou 24 de façon à permettre un entraînement manuel aisé mais offrant cependant une résistance suffisante pour maintenir sans jeu une monture M entre les réglettes 8, 9.This braking action is adjusted by means of the nut 24 so as to allow an easy manual drive but nevertheless offering sufficient resistance to maintain without play a mount M between the strips 8, 9.

Dans une variante, représentée à la figure 4, la poulie 14 est entraînée par un dispositif motoréducteur 25 de type connu comportant un commutateur 26 de marche avant-marche arrière-arrêt.In a variant, shown in FIG. 4, the pulley 14 is driven by a geared motor device 25 of known type comprising a forward-reverse reverse-stop switch 26.

De façon avantageuse, et comme connu en soi, le porte-monture suivant l'invention peut comporter un support oscillant 27 articulé sur la réglette 8 (ou 9), et un pied de centrage 28 fixé sur la réglette 9 (ou 8).Advantageously, and as known per se, the frame holder according to the invention may include an oscillating support 27 articulated on the strip 8 (or 9), and a centering foot 28 fixed on the strip 9 (or 8).
