Definitions
- the present invention relates to a spectacle frame holder of the type comprising two jaws, at least one of which is slidably mounted so that the jaws can come together or move away from each other, and means of support adapted to hold the frame between the jaws in a reference plane.
- the clipping of a shaped optical glass of a spectacle frame requires grasping with precision in a computer memory the shape of the mount. This is done using a device capable of palpating the circles of the frames.
- the means of support may consist of collets of the movable frame perpendicular to said plane of reference, or by V-shaped centering devices integral with the jaws.
- the mount is applied to one of the jaws, to guarantee that it is "planed", that is to say that it is not in an oblique position, in the reference plane, during probing, and on the other hand that it is not deformed by its tightening between the two jaws, even if the frame is easily deformable in its plan as it is for many models with very thin metal circles.
- the subject of the invention is a spectacle frame holder of the aforementioned type, characterized in that at least one jaw is equipped with at least one sensor adapted to provide an arrival signal of this jaw in an activation position of the means of maintenance during the mutual approximation of the two jaws.
- the frame holder according to the invention can have one or more of the characteristics of claims 2 to 10.
- the frame holder also includes two horizontal support rods 4 parallel to the rods 3, located between them and retractable laterally, parallel to themselves, following the teaching of FR-A-2 720 524 cited above.
- each jaw In the vicinity of the end of each rod 4 in active position, each jaw includes a gripper 5, of any known type suitable, the two jaws of which are vertically movable.
- the rods 4 are adapted for supporting a spectacle frame 6 comprising two circles 7 connected by a bridge 8.
- the jaw 1 located on the side of deck 8 is called the upper jaw, and the other jaw 2 is the lower jaw.
- the lower jaw 2 is substantially equipped in the reference plane P defined by the rods 4 in active position, and halfway between them, by nose 9 projecting towards the jaw 1 and of convergent shape towards that jaw.
- the nose 9 is integral with a horizontal pin 10 parallel to rods 3 and 4 and guided sliding in a bore 11 of the jaw 2.
- a spring 12 of low stiffness housed in a counterbore 13 of the jaw and surrounding the pin 10, urges the nose 9 to the position shown, which is the one where it projects the most compared to the jaw 2.
- the jaw 2 has a position sensor 14.
- This sensor is essentially consisting of a vertical plate 15 secured to a horizontal contact rod 16 parallel to rods 3 and 4 and guided in the jaw 2, and from spring 17 slightly less stiff than spring 12, surrounding the rod 16 and urging the plate 15 up to in the position shown, where it is slightly protrusion from the jaw 2.
- the rear end rod 16 is located next to a switch electric 18 connected by a wiring 19 to a unit of electronic control 20.
- Unit 20 then operates the four clamps 5, which close and hold firmly in place the frame for its probing ( Figure 7).
- the clamps 5 can be operated manually after the jaws have stopped.
- the position sensors 14 are arranged in the funds of vés. They are arranged so that the contacts 16-18 are established when the plates 15 are level with these funds.
- the movements of the jaws can be controlled manually, for example by a screw-nut system as described in FR-A-2 720 524 cited above.
- the sensors 14 then emit a signal warning, optical and / or audible, which informs the operator of the correct relative position of the two jaws.

Abstract
Description
- la Figure 1 représente en plan, de façon schématique, un porte-monture de lunettes conforme à l'invention, en position écartée des mâchoires;
- la Figure 2 est une vue de côté correspondante, prise suivant la flèche II de la Figure 1;
- les Figures 3 et 4 correspondent respectivement aux Figures 1 et 2, mais pour une position intermédiaire de rapprochement des mâchoires;
- les Figures 5 et 6 correspondent respectivement aux Figures 1 et 2, mais pour la position finale de rapprochement des mâchoires;
- la Figure 7 est une vue analogue à la Figure 6, mais après fermeture des pinces de maintien;
- les Figures 8 et 9 sont des vues analogues aux Figures 1 et 2 respectivement, mais relatives à bine variante du porte-monture de lunettes; et
- la Figure 10 est une vue analogue à la Figure 9, mais dans la position finale de rapprochement des mâchoires.
Claims (10)
