Definitions

  • the present invention relates to spectacle parts such as alloys and bridges having a structure that can be directly attached to lenses of rimless spectacles.
  • the spectacles include a pair of left and right lenses, a main body rim that holds the pair of lenses from the side of the lens and serves as a main body of the spectacle frame, and a nose pad and a temple for locking the nose and ears of the spectacle wearer. It is composed of parts such as locking rods (temple end, earpiece).
  • rimless glasses without a lens frame (rim) are popular because they are lightweight and have a wide field of view.
  • rimless glasses do not have a rim, it is not possible to attach the Yolo Bridge to the rim. Therefore, make a hole directly in the lens and use a screw pin (in this case, generally use a lip).

  • the document describes a structure in which an edge contact portion of the wire is provided, the penetrating portion is fitted into the bridge fixing hole, and the prism is fixed to the lens so that the lens is sandwiched between the two edge contact portions.
  • This structure can also be applied to brackets (ji, yoro).
  • Glasses (WO 94/02876) describes a method of attaching bridges, metal alloys, pats, and the like directly to a lens with elastic holding pieces.

  • the above-mentioned method is used to attach eyeglass parts such as European bridge to the lens without using screw pins, etc., but when attaching external parts with a simple structure, just using the metal's own natural power Stable fixing is difficult. For this reason, the method of complicating the shape of the holding portion of the component or processing the shape of the portion where the lens contacts the holding piece in various ways is adopted.
  • An object of the present invention is to provide a spectacle component such as a yoro bridge having a simple structure, and which can be easily and stably mounted.
  • the present invention aims to develop eyeglass parts having a strong structure that can be attached to a lens without using a screw or a pin because rimless eyeglasses using a single metal member are included in the field of view. The purpose is. Disclosure of the invention
  • the elastic force is increased by changing the shape of the wire-like member used for the European bridge.
  • One of the methods is to make the part in contact with the outer periphery of the lens into a ring shape.

  • Another advantage of using pipe members is that they are easier to swage. More specifically, the parts have the following shapes.
  • a spectacle lens is provided with a bearing hole, a notch of a spring ring is provided on the outer periphery of the lens, and a fitting shaft and a panel wheel to be fitted with the notch of the spring ring are provided at the distal ends of the wires serving as bridges and metal alloys.

  • the lens 1 is provided with a bearing hole 110 and a spring receiving notch 120. Align the spring ring with one end of the fitting shaft in the direction of the arrow, and insert the fitting shaft into the bearing 3 ⁇ 4J.
  • Figure 2 shows the bridge attached to the lens. When the tip 211 of the fitting shaft is swaged, the mounting of the bridge is completed.
  • the inside and the certain direction indicate the face side when wearing glasses, and the outside and the opposite direction indicate the face.
  • the metal fitting 3 is provided with a fitting shaft 310 and a spring wheel 320
  • the lens 1 is provided with a bearing hole 110 and a panel wheel receiving notch 120. Insert the fitting shaft into the bearing hole while aligning the spring ring with the panel wheel receiving notch in the direction of the arrow, and swage the tip 311 of the fitting shaft to complete the mounting (Fig. 4).
  • the end opposite to the fitting axis of the holoy has a hinge mechanism (for example, a hinge), which is connected to the temple (omitted in the figure).
  • Spring rings are basically circular, but need not be circular. Rather, the portion corresponding to the notch of the lens is preferably shaped along the notch groove (usually a straight line). Both Yoroi and the ridge are made of a single wire-like metal, so the spring ring is spiral. Also, the bearing holes and panel wheel notches cut out in the lens are machined into the outer shape of the parts. In particular, the notch is a groove to prevent the spring ring from shifting, but if excessive force from the parts is applied, it may cause the lens to crack, so as shown in Fig. 5, the spring ring 220/320 Make a semicircular depression slightly shallower than the radius.
  • the fitting shaft When caulking, the fitting shaft is fixed to the lens so that the tip of the fitting shaft is slightly wider than the diameter of the bearing hole of the lens. Therefore, when using a soft metal such as gold (for example, 8K) as a part, the inside diameter of the pipe is pressed with a rod slightly larger than the inside diameter to open the pipe entrance and fix the fitting shaft to the lens. It is also possible to do this. For example, as shown in FIG. 8, if the screw 9 is inserted inside the tip 211 of the fitting shaft and the screw is turned, the entrance is widened and the fitting shaft is fixed to the lens. Of course, in this case as well, if a cut is made, the entrance can be easily expanded. And after swaging, you can remove the screws. When the screw is removed, a metal piece to close the hole can be fitted.

  • FIG. 9 is a completed view when the bridge 2 and the metal alloy 3 are attached to the lens 1 by the above method.
  • the pad is not attached in the figure, but the pad is attached to the bridge.
  • the pad is attached by attaching one end of the pad leg (the connection part between the pad and the metal) to the bridge. It is also possible to attach the pad directly to the lens. In that case, the same method as for the bridge can be used. However, notching a large number of holes or notches in the lens is not always desirable in terms of lens strength and field of view. Industrial applicability
  • the present invention provides a simple spectacle structure for finishing rimless spectacles using a single metal material, and parts therefor.
  • the structure is simple and luxurious, especially when gold, which is popular with customers, is used.
  • the feature of the present invention lies in that the use of a pipe-shaped wire as a part achieves weight reduction while maintaining strength.
  • the use of pipe-shaped wire makes caulking easier. Since no screws are used, component loss due to loose screws is avoided. Also, because of the small number of parts, it is easy to assemble and has a cost-effective part configuration.
  • the portion for holding the lens is a panel wheel.
  • the use of the spring wheels has increased the force with which the part sandwiches the lens, and strengthened the prevention of loosening of the part.
  • the spring ring disperses the force applied to the parts and lens by the panel wheel, so even if an unexpected situation occurs and the glasses are strongly applied, the parts or lens will be damaged. Danger is reduced. This point is also a feature of the present invention due to the spring ring structure.

Abstract

L'invention porte sur une partie de lunettes telle qu'un tenon rapporté ou pont dont la structure permet de le fixer directement sur un verre de lunettes sans cercle. L'invention porte sur des lunettes sans cercle qui, en vue de mettre au point une partie d'une paire de lunettes pouvant se monter sur un verre sans utiliser de vis ou de broches et ayant une structure renforcée, comportent un pont et un tenon rapporté conçu dans un fil métallique et adapté pour être monté directement sur le verre. La partie sans cercle d'une paire de lunettes est caractérisée en ce que le pont et le tenon rapporté sont pourvus d'une section retenant le verre comprenant un anneau à ressort formé en courbant le fil métallique et une tige de montage adaptée pour se fixer dans un trou formé dans le verre de manière à retenir le verre et l'anneau à ressort, et est également caractérisée en ce que le fil métallique a une structure creuse dans laquelle il peut être serti par déformation par pression ou une structure sertissable dans laquelle l'extrémité de la tige de montage est formée à l'intérieur par un creux de vis de façon à pouvoir effectuer le sertissage par déformation par pression et à visser l'extrémité de la tige dans le creux.
