    PAIR OF GLASSES WITH ATTACHMENT OF WAFER ARMS
    IMPROVED The invention relates to a pair of spectacles whose attachment of the wafer arms is improved.
    In the glasses of the prior art the wafer arms are fixed in different ways: they can be fixed to the glasses, as described in GB775293, EP0081179, US5790230; they can alternatively be fixed on the face of the pair of glasses, as described in documents JP2007240700, CN201335916Y, CN200976071Y and CN200972546Y.
    These different solutions require to arrange specific configurations on the glasses or on the face of the pair of glasses. The arrangement of such configurations is likely to complicate the production line of pairs of glasses, including increasing the number of operations to be performed and sometimes complicating certain operations.
    It would therefore be useful to simplify the attachment of the wafer arms to a pair of spectacles.
    The subject of the present invention is therefore a pair of spectacles comprising: a face which comprises two circles, two glasses mounted respectively in the two circles of the face, two wafer arms, characterized in that each wafer arm comprises at least one portion which is positioned between one of the two lenses and the corresponding circle in which said lens is mounted to lock said wafer arm in position.
    The configuration of such a pair of glasses is particularly simple. Indeed, it is the mounting of each of the glasses in a circle which ensures the holding in position of said at least a portion of each wafer arm, and therefore of each wafer arm, between the glass and its corresponding circle (locking position). It is therefore not necessary to provide complex arrangements on the glasses and / or the face to fix the pad arms. The process of manufacturing pairs of glasses is thus greatly simplified.
    According to other possible features: each circle has an inner peripheral surface and each glass has an outer peripheral surface, said at least one part of each plate arm being locked in position between the two peripheral surfaces facing each other. one of the two glasses and the corresponding circle in which said glass is mounted; the inner peripheral surface of each circle has a cutout in which the at least part of one of the two wafer arms is at least partially inserted; this very simple arrangement of each circle allows to install said at least a portion of one of the two wafer arms on the face; the two inner peripheral surfaces of the two circles being spaced apart from each other in the face of the pair of spectacles, the two cuts are made, for example symmetrically, respectively in two portions of the two inner peripheral surfaces of the two; circles; the two portions of the two inner peripheral surfaces of the two circles are for example the portions which are closest to each other in the face so that the cuts are as close as possible to one another; at least a portion of each wafer arm comprises a pin which is locked in position between the two peripheral surfaces vis-à-vis one of the two glasses and the corresponding circle in which said glass is mounted; the pin is for example inserted into one of the two peripheral cutouts of the circles; at least a part of each wafer arm and the corresponding lens cooperate with each other by inserting a projecting element of one into a hollow of the other to ensure the locking in position of the wafer arm; this nesting allows for a durable assembly over time that is able to withstand the many manipulations to which the pair of glasses is subjected; -ladite at least a portion of each wafer arm and the corresponding circle cooperate with each other by inserting an element protruding from one into a hollow of the other; this interlocking is an additional interlocking relative to the previous one and which ensures better mechanical strength of the assembly when the wafer arms are subjected to manipulations, in particular deformations during installation and adjustment / adjustment on the nose a carrier; the pair of spectacles comprises a bridge assembly which comprises the two wafer arms and a bridge connecting the two wafer arms to each other; both wafer arms may be symmetrically disposed relative to each other although this is not a necessity. The subject of the invention is also a method for assembling elements of a pair of spectacles, the pair of spectacles comprising, as elements to be assembled, a face that comprises two circles, two lenses intended to be mounted in the circles and two wafer arms, characterized in that the two glasses are mounted respectively in the two circles by positioning at least a portion of a wafer arm between each glass and the corresponding circle in which said glass is mounted so that the two wafer arms are locked in position by mounting the glasses in the corresponding circles. This assembly is particularly simple to perform and effective. The same advantages as those described above in relation to the pair of glasses also apply to the process.
    According to other possible characteristics: at least a portion of each of the two wafer arms is previously positioned on one of the two circles; this position of the wafer arms is the final position; the two glasses are then mounted in the two corresponding circles, thus blocking in position each of the two wafer arms between a glass and the corresponding circle; the two wafer arms are thus locked in their final position. Other features and advantages will become apparent from the following description, given solely by way of nonlimiting example and with reference to the appended drawings, in which: FIG. 1 is a general schematic view of all the elements to be assembled of a pair of spectacles 10 according to one embodiment of the invention; FIG 2 is a sectional view in a horizontal plane of the pair of glasses 10 with the assembled elements; FIG. 3 is an enlarged view of a portion of the pair of spectacles of FIG. 2; FIG. 4 illustrates an alternative embodiment of one of the elements of FIGS. 1 to 3; FIGS. 5a and 5b are partial schematic views of a possible additional connection between a circle and a wafer arm.
    Figure 1 shows different separate elements of a pair of spectacles 10 according to one embodiment of the invention. When these elements are assembled with each other they form the pair of glasses 10. These elements will first be described with reference to Figures 1 to 3 before a method of assembling these elements is described. In Figure 1 these elements have the same spatial orientation that they have when the pair of glasses is worn by a user or when the pair of glasses is placed on a horizontal support with the bezel branches (not shown) deployed. The vertical axis Z is shown in FIG.
    As shown in FIG. 1, the pair of spectacles 10 comprises the following elements to be assembled: a face 12 which comprises two circles 14 and 16, two glasses 18 and 20 intended to be mounted respectively in the two circles 14 and 16 of the face, two wafer arms 22 and 24.
    The face of a pair of glasses is the term commonly used in the field of eyewear to designate the portion of the pair of glasses welcoming glasses and which is positioned on the nose of a user.
    The term "circle" is the term commonly used in the field of eyewear to designate a recessed portion of the face of the pair of glasses that accommodates a glass, without imposing a geometric shape particular to this part. One face has two circles. Circles 14 and 16 for receiving glasses 18 and 20 do not necessarily have a circular shape.
    The terms "wafer arm" designate elements of the pair of spectacles, generally symmetrical to each other, each of which accommodates a wafer support and a wafer. The pads are intended to rest on the two wings of the nose of the user. Note that the wafer arms may not be symmetrical to each other according to the embodiment.
    The other conventional elements of a pair of spectacles such as the branches and the possible end pieces will not be described here but may be present in the pair of spectacles according to the embodiment described.
    The aforementioned elements (circles, glasses and wafer arms) are configured to be assembled together and form a pair of glasses of improved design, particularly with respect to the assembly and attachment or holding in the assembled position of the wafer arms.
    In general, the wafer arms 22, 24 each comprise a so-called contact portion. The wafer arms 22, 24 are to be assembled, via their respective contact portions, with the glasses 18, 20 and the corresponding circles 14, 16 in which the lenses are to be mounted. According to this assembly, each wafer arm is held in position on the face 12 (locking in position) by mounting one of the two glasses in its circle as shown in Figures 2 and 3.
    The following description of the embodiment relates to a possible example of eyeglass elements to be assembled according to this principle to form a pair of glasses of improved design.
    In the example described, the two wafer arms 22, 24 form part of a bridge assembly 30 visible in FIGS. 1 to 3. In FIGS. 2 and 3, the bridge assembly 30 is shown in assembled position with the face 12. The bridge assembly 30 comprises a bridge 32, here rod-shaped, which connects transversely the two wafer arms 22, 24.
    The bridge 32 extends horizontally when the face 12 is oriented vertically as in Figure 1 (pair of glasses worn by a user or placed on a horizontal support).
    The two wafer arms 22, 24 are symmetrical to one another with respect to a median vertical plane perpendicular to the bridge 32. This plane P is identified in the horizontal plane of FIG. 2.
    The wafer arms 22, 24 each form two lateral extensions of the bridge 32 which extend from said bridge and away from it in different directions.
    Only the description of the wafer arm 22 will now be performed, the description of the other wafer arm 24 being identical.
    The wafer arm 22 (FIG 1) mainly comprises, on the one hand, a first lateral extension 22a directed downwards and which extends below the side of the bridge 32 and, on the other hand, a second extension 22b which extends substantially to the same dimension as that of the bridge and, in the majority, in a direction which is substantially perpendicular to that of the bridge.
    The first downward lateral extension 22a serves to carry the wafer support and the wafer not shown here.
    The second lateral extension 22b includes the contact portion of the wafer arm mentioned above which is assembled and held in position between the glass 18 and its circle 14 (Figs 2 and 3).
    The second lateral extensions of the two wafer arms 22, 24 arranged in conjunction with the bridge 32 give the assembly, in plan view (FIG 2), a general shape of fork or U which extends in a horizontal plane. . The contact portions of the wafer arms form the branches of the fork and are intended to be inserted into the face 12 as illustrated in FIGS. 2 and 3.
    The following description of the wafer arm 22 is more detailed than the foregoing but is in no way limiting. Other embodiments are possible.
    The first downward lateral extension 22a comprises several segments (FIG. 1): a first segment 22a which extends substantially perpendicular to the bridge 32 and horizontally (this first segment extends in the plane formed by the bridge 32 and the second extensions side of the two wafer arms 22, 24), a second segment 22a2 connected to the first segment for example by a bend and which extends downwardly forming an inclination with the vertical of the place where the first segment ends, the inclination being such that the second segments of the two wafer arms extend downwardly away from one another in a front view of the bridge assembly 30 (the angular spacing is visible on the figure 1).
    The second segment 22a2 extends perpendicular to the bridge 32 in a side view (view along F in Figure 3).
    The second segment 22a2, longer than the first segment 22al, has at its free end a hollow wafer arm housing, noted 22a3. This housing 22a3 is open towards the symmetrical housing of the other arm 24. The housing is pierced with two opposite through orifices which serve to mount an axis or screw for the articulation of the wafer support (the axis and the support are not shown here for the sake of clarity).
    The first segment 22a1 is connected here to the bridge 32 near one 32a of the two opposite ends of said bridge 32 (FIG 3).
    The second lateral extension 22b of the wafer arm comprises the contact portion 22bl which takes for example the form of a pin or a pin which extends from the end 32a of the bridge in a direction opposite to the first segment 22al, parallel to this one. The contact portion 22b1 is not aligned with the first segment 22a1 but is shifted transversely thereof from a small distance represented by the segment 22b2. The segment 22b2 may be considered as belonging to the second lateral extension 22b (the second lateral extension 22b thus forms a hook with respect to the first segment 22al) of the wafer arm or forming part of the bridge 32.
    The contact portion 22b1 is configured to cooperate with the glass 18 of FIG. 1 and, for example, to allow a fitting of a projecting member of the glass in a recess of said contact portion or vice versa.
    This arrangement provides a more durable mounting time of the glass in its circle to prevent the glass from slipping over time on the contact portion 22bl.
    In the example shown, the pin 22bl has a recess or notch "e" arranged on the outer face of the pin, that is to say on the face which is directed towards the outside of the bridge assembly 30 and not the face which is opposite the pin of the other wafer arm 24. The projecting element of the glass 18 (complementary to the hollow of the pin for the interlocking) is formed by the outer peripheral surface (edge peripheral) of the glass which is bevelled 18a (FIG 3) around the circumference.
    Note that the bridge assembly 30 including the wafer arms 22, 24 is made of a rigid material but is able to deform elastically to get used to the wearer, especially the width of his nose.
    In the example illustrated in the figures the bridge assembly 30 is formed in one piece, which avoids areas of weakness where different portions or segments of the part would be fixed to each other, by welding or by any other technique. The bridge assembly 30 is here a metal piece which is for example derived from a metal plate. The piece is obtained by cutting to form a general structure in the form of H, then by folding areas of the structure that will form the wafer arms. The part is made of solid material and not hollow except for the case 22a3.
    The face 12 comprises a central portion 15, also called the face bridge, which separates and connects the two circles 14, 16 and extends in the same directions of extension as the circles. In the illustrated example, the extension directions are in a curved surface, since the face 12 is not flat (FIG 2). The face 12 also extends in a direction perpendicular to a dimension, called thickness, which is small relative to the perpendicular dimensions of the face.
    Note that the shape and dimensions of the central portion 15 may vary.
    The face 12 has two surfaces, a concave inner surface 12a (intended to be placed facing the eyes of the user and which matches the general shape of this part of the face) and a convex outer surface 12b.
    In other possible embodiments, the face may be less curved or even flat.
    Each of the two circles has the same configuration and therefore only the circle 14 will now be described with reference to FIG.
    The circle 14 more particularly comprises a recessed central portion 14a and a peripheral portion 14b delimiting the central portion.
    The peripheral portion 14b comprises two peripheral edges 14b1, 14b2 parallel to each other which each form a peripheral contour delimiting the central portion 14a.
    The two peripheral edges 14bl, 14b2 are spaced from each other in the transverse direction and define between them a groove G in which the glass 18 is intended to be inserted. The groove G extends, generally in annular form, radially around the periphery of the recessed central portion 14a and away from it.
    The two peripheral edges 14b1, 14b2 define with the groove G an inner peripheral surface of the circle 14.
    A cut DI is made in each of the two peripheral edges 14b1, 14b2 as well as in the bottom of the groove G in a portion of the circle which is adjacent to the central portion 15. The cut DI extends axially in the direction perpendicular to the The cut corresponds locally to a removal of material in the two peripheral edges 14b1, 14b2 as well as in the bottom of the groove G in a radial direction relative to the central recessed portion 14a and away from it.
    Thus, as shown in FIG. 1, the two portions of the two circles 14 and 16 in which the cutouts DI and D2 (cutting on the circle 16) are made are preferably the portions of the circle (facing portions) which are the most close to each other in the face 12. In other words, the width of the central portion 15 (extension dimension of the central portion between the two circles) at the place where the cutouts DI and D2 are made is the smallest width of the central part. This location of the cutouts on the face 12 thus makes it possible, on the one hand, to minimize the volume of material used for the bridge assembly 30 and, on the other hand, to simplify the shape of the bridge assembly 30. a different location of the cuts is also possible.
    The cutouts DI and D2 are, for example, symmetrical to one another with respect to the central portion 15. The two cutouts thus form a reception zone for the wafer arms in the face 12.
    Each glass 18, 20 has the outer peripheral surface shaped bevel as described above for the glass 18 so as to fit into the corresponding wafer arm as will be seen below.
    According to an exemplary method of assembling the elements described above (circles, glasses and wafer arms), the bridge assembly 30 is first mounted on the face 12 on the side of the inner surface 12a to be positioned in the reception area. The bridge assembly 30 is thus positioned in this zone by insertion of the pins respectively into the cuts DI and D2.
    The two pins of the two pad arms are spaced from each other by a distance which is slightly less than the spacing between the respective bottoms of the two cutouts D1, D2, so as to obtain a tight fitting of the pins in the cuts. The bridge assembly thus mounted in its final (operational) position on the face 12 is mechanically connected to this face 12 in such a way that a mechanical force of tearing or extraction (for example a manual effort) is necessary for separate the deck set from the face.
    Then, the glasses 18, 20 are respectively mounted in the circles 14, 16 one by one, momentarily elastically deforming the face 12 to introduce each of the glasses inside the groove G. This mounting is performed so conventional.
    Each glass inserted into the groove G then engages with its bevelled outer peripheral surface in the notch of the corresponding pin (the bevel 18a is inserted into the notch e in Figure 3).
    When the glass is thus mounted, the pin is locked / locked in position between the inner circumferential surface of the circle and the outer peripheral surface of the glass. In other words, the pin is trapped between the inner peripheral surface of the circle and the outer peripheral surface of the glass. This arrangement thus ensures the locking / locking of the final (operational) position of the wafer arm relative to the face 12.
    Note that the wafer arm does not necessarily include a hook as shown in Figures 1 to 3. The contact portion (eg picot 22bl) can indeed be placed in alignment with the first segment 22al in view .
    Figure 4 illustrates a bridge assembly 130 according to an alternative embodiment. The bridge assembly 130 comprises a bridge 132 connecting transversely between them the two wafer arms 134, 136.
    This set differs from that of Figures 1 to 3 in two aspects: -the bridge 132 is curved upwards and no longer rectilinear as the bridge 32; the two lateral extensions of each of the wafer arms 134, 136 are aligned with each other: the descending lateral extensions 134a and 136a have been spaced from each other to come into alignment with the respective lateral extensions 134b and 136b which form the active parts (eg pins). This spacing provides an ergonomic gain in terms of adaptation to the wearer's nose.
    Note that these two aspects may not necessarily be present simultaneously. Thus, the two lateral extensions of each of the wafer arms 134, 136 are aligned with each other but the bridge 132 does not have a curved shape.
    Figures 5a and 5b illustrate two alternative embodiments of an additional arrangement possible in the embodiment of Figures 1 to 3 and its variants.
    This arrangement provides an additional connection by interlocking between the active part (eg picot) of a wafer arm and the corresponding circle. This makes it possible to limit the forces exerted on the glass when the optician adjusts the pad arms by deforming them in order to adapt them to the nose of the wearer.
    In FIG. 5a, the circle 140 comprises, at the bottom of the cutout D ', a projecting element 140a and the active part 142 presents opposite a hollow 142a in which the projecting element is inserted to make the additional connection. This arrangement is added to the interlocking between the glass and the active part via its notch e already described with reference to Figures 1 to 3.
    Alternatively, in Figure 5b, the circle 150 has, at the bottom of the cut D ", a recess 150a and the active portion 152 has opposite a protruding member 152a which is inserted into the recess to provide the additional connection. This arrangement is added to the interlocking between the glass and the active part via its notch e already described with reference to Figures 1 to 3.
    These different arrangements can be combined with the previous embodiments and variants.
    In particular, the active portion 142 or 152 may comprise a projecting element instead of a notch to cooperate by engagement in a hollow of the glass.
