Definitions
- the invention relates to devices for fixing a hinge element on a branch or a molded front of a spectacle frame.
- Simple, non-elastic hinges are known, provided with a fixing member in the form of at least one claw which generally has the shape of a T.
- the hinge element-fixing member assembly is arranged at one end of the branch or of the facade and the fixing member is thus molded by the molded material so as to anchor the hinge element in this branch or facade.
- This case is welded to a T-piece recalling the shape of the non-elastic hinge fixing member.
- the T-shaped fixing member is embedded in the plastic, which ensures the anchoring of the housing which will remain clear on the inner face of the branch.
- the spring mechanism can be of the slide or rod type well known in this technical field.
- This elastic mechanism is installed in a housing obtained by a cover and it is connected to the branch knuckle which is thus made displaceable against the effect of the action of the spring of the mechanism, while the front hinge element is mounted fixed. at one end of the facade.
- the housing constituting a housing for the spring mechanism can also be manufactured by the MIM technique (from English Metal Injection Molding) which is an injection molding technique of a mixture of a metallic powder with a thermoplastic binder in a mold.
- MIM from English Metal Injection Molding
- the manufacturing technique by MIM of such a housing for an elastic hinge is described in document EP-A-0 817 987 and will not be explained in detail either.
- the known fastening devices for a hinge element cannot be used on relatively thin branches or facades since it takes a certain thickness so that the fastening member can be well anchored.
- the device for fixing the hinge element of the branch of the elastic hinges is relatively complicated to implement since it is also necessary to carry out the operation consisting in fixing the housing to the T-shaped fixing member.
- the object of the invention is to remedy these drawbacks by proposing a device for fixing hinge elements which is easy to implement in general, but especially on elastic hinges, and which is particularly well suited for use on thin branches or facades.
- the fixing device according to the invention provides an additional advantage in that it can constitute an embellishment without the need to add parts.
- the invention relates to a device for fixing a hinge element for a spectacle frame, comprising a fixing member associated with the hinge element and anchored by overmolding in a branch or a frame facade obtained by molding, characterized in that the fixing member comprises a first plate which carries the hinge element and which by means of a central bridge is connected to a second plate, said central bridge extending transversely in said branch or facade entirely by being completely embedded in the molded material of said branch or facade.
- the plates have a peripheral surface which has been used for sealing during the overmolding of the branch or of the facade; - Said first plate is directly connected to the hinge element;
- the housing of the elastic mechanism is a housing constituted by an attached cover and fixed on the surface of said first wafer;
- - Said fixing member is manufactured by the MIM process; - Said fixing member and said housing are made in one piece by the MIM process.
- FIG. 1 is a side view, partially in section , showing two devices according to the invention for fixing the branch hinge elements and the front of a non-elastic hinge;
- FIG. 2 is a side view, partially in section, showing two fastening devices according to the invention, one being associated with a housing of an elastic hinge, and the other being associated with a hinge element from the front ;
- FIG. 3 is a perspective view of a fixing device according to the invention, associated with a housing housing a mechanism of an elastic hinge;
- FIG. 4 is a perspective view of the fixing device of Figure 1, turned 180 °;
- FIG. 5 is a longitudinal sectional view of the fixing device of Figures 3 and 4, mounted on a branch end;
- FIG. 6 is a cross-sectional view of the device and of the branch of FIG. 5.
- FIG. 1 shows two fixing devices according to the invention, in an application to a non-elastic hinge.
- Each fixing device comprises a member for fixing a hinge element 1, this device comprising a first plate 2 and a second plate 3 which are connected to each other by a central bridge 4. These two plates are substantially parallel to each other.
- the fixing member 1 of one of these devices is connected to the two front knuckles 5, which constitute a female hinge, while the fixing member of the other device is connected to the branch knuckle 6 which constitutes a male hinge.
- the branch knuckle 6 is usually connected to the front knuckles 5 using a pivot screw 7 to form the articulation between the branch 8 and the front 9.
- the hinge assembly-corresponding fixing device is arranged in the mold so that the central bridge 4 extends transversely in the branch, perpendicularly to the longitudinal axis thereof.
- the central bridge is completely embedded in the molded material.
- the second plate 3 which is used only for fixing the hinge element, while the latter is carried by the first plate, projects laterally outside the outer surface of the branch and thus has a surface which advantageously constitutes a hubcap 10 which can bear a design, a trademark, etc.
- hinge elements with the fixing devices according to the invention can be manufactured by machining, they are preferably manufactured by the MIM technique mentioned above, which consists in mixing a binder in a metallic powder having a very fine particle size , injecting the mixture into a mold, and expelling the binder by disintegration and evaporation to thereby obtain a blank which has the desired shapes and which is then sintered, which gives the final shape after a certain shrinkage. It is a technique which is now perfectly mastered and which is particularly well suited to the manufacture of parts of small dimensions and of complicated shape, while obtaining a relatively high precision. Thus, different patterns on the hubcap can easily be obtained by this molding.
- FIGS. 2 to 6 show another embodiment applied to an elastic hinge. Elements similar to those already described in the embodiment of Figure 1 have the same references.
- the device for fixing the front hinge element 5 is practically identical to that described with reference to FIG. 1, while in the embodiment illustrated in FIGS. 2 to 6, the device for fixing the hinge element branch hinge 6 is associated with a housing 12 comprising a housing 13 for the spring mechanism of the elastic hinge.
- the details of the elastic mechanism are not described since they are well known and do not relate directly to the invention. It is only recalled that this mechanism allows the branch hinge element to move in translation when the branch is pivoted inward or outward, thereby bringing the branch resiliently in one of the two stable positions, that is to say folded (rest) or deployed (use). This mechanism allows an angular displacement of the branch towards the outside beyond the so-called “use” position.
- Such hinges provide an element of comfort in the wearing of the telescope because the arms are pressed against the temples with reasonable pressure.
- the housing can be formed by an attached cover and fixed to the first wafer by welding, but preferably, and as is the case in the illustrated embodiment, the housing 13 came integrally, that is to say in one piece, with the fixing device and it is more precisely arranged on the first plate 2 of the fixing member 1.
- the housing can be part of a single piece machined after it is obtained in a conventional manner by turning and cold stamping, but it is advantageously formed in a part obtained by the MIM technique. To form the housing of the housing, it suffices to integrate a pin into the MIM molding to make the housing.
- a housing is thus obtained which is open on one side for the introduction of the spring mechanism which must be fixed to it, for example using a screw screwed into a hole 14 and cooperating with an element constituting a stop of the spring of the mechanism.
- the central bridge has an elongated shape and it is pierced by holes 15 regularly arranged and aligned with one another. These holes improve the grip of the molded material during the molding of the branch.
- a fastening device is thus obtained which gives an extremely reliable anchoring in a branch or front of glasses, which is particularly well suited to the manufacture of thin branches, and which in addition has an external surface which can form a hubcap.
