Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to eyeglass assemblies.
[0002]
The present invention can be used particularly in the field of manufacturing and selling lightweight multipurpose glasses, but is not limited thereto.
[0003]
[Prior art]
Eyeglass frames are well known, they are mainly used to hold the lens, ie the front part formed by two rings of glasses and connected to each other by an intermediate bridge, and sometimes said 2 It is composed of a nose pad formed integrally with one ring and two support arms.
[0004]
There are various solution configurations on the market, of which the most important solution configuration is, for example, EP 546589 (Lindberg), the challenge for lenses of glasses, in particular with wire-type frames. It is to provide a support means. Various variants of this main problem have also been described, in particular with regard to the support structure for the lens, in this case in one variant the wire is configured to run only along the lower part of each lens. In another variation, it is configured to run along the upper portion of the lens. As a result, the wire is bent and twisted to form one arcuate structure which acts as a connection for hinged arms on both sides of the glasses and 2 by a bridge in the middle. It acts as a connection for holding a single lens, and also acts as a fixed point for each nose pad.
[0005]
Other types of glasses are also known that are formed by an arcuate frame that uses only the upper arcuate portion to hold both lenses.
[0006]
The conventional type is intended for a lightweight arcuate frame, for example made of plastic or metal material, and by its shape it runs left and right only in its upper part. In this way, both lenses are fixed with respect to the arcuate part of the glasses. Specifically, a number of holes are formed along the upper edge of the lens, through which these fixation points formed perpendicular to the frame are inserted. These fixation points are small studs with threaded ends that are attached through corresponding holes formed in the lens and then tightened with a small star or other type of nut. A development of this configuration is described in WO 02/10840 (Tabacchi), which consists of a support arcuate member for a replaceable lens holder, which has both lenses in the front arcuate part. Or, to fix the visor, no screws or nuts are required to fix it to the base.
[0007]
The second conventional configuration is also an arcuate structure, which forms two counter-shape portions on its sides, each of which is associated with the associated lens to which it is attached. It is formed in an arc shape so as to fit the curved profile. Similarly, a bridge portion that is curved and connects the two portions and holds both lenses is formed integrally with the two portions by molding the specific portion of the connection wire. The outer ends of the two arcuate parts, i.e. both ends of the arcuate part, are bent about 90 ° with respect to the rear part of the spectacles and corresponding to the swing of the arm soldered to it. A hinge connection is provided. Each of these parts is further soldered to the upper part of the metal wire and also includes hooks or clips protruding therefrom, which are used to hold both lenses against the arcuate part.
[0008]
It is also well known that there are people who need to wear prescription glasses that protect their eyes from sunlight without compromising their appearance. The options in these cases are somewhat limited and are conditioned by factors such as lens strength and the environment in which the glasses are primarily used. One solution that is currently available to consumers is a visor-type mounting structure, which is mounted on an existing lens of eyeglasses, with a clip in its main front, and usually It is fixed along the upper arcuate part of the glasses and the bridge.
[0009]
Specific examples of the first configuration that is a clip type similar to that described above and that allows the eyeglasses to hold the second lens holder with the protective lens include, for example, WO93 / 24856 (Salk) and U.S. Pat. No. 6,257,718 (Spencer).
[0010]
Prior art closest to the present invention U.S. Pat. No. 6,382,977 (Xie) describes glasses with clips. The clip is arranged corresponding to the bridge of the attachment part and is directed to the rear part of the glasses. This clip connecting the mounting part to the corresponding frame overlaps and locks the corresponding bridge of the support frame to which both associated arms are connected. Finally, the entire assembly is stabilized by a large number of magnets attached to the attachment portion corresponding to the nose rest.
[0011]
US Pat. No. 6,283,591 (Chen) also describes an attachment, in which case it is a spectacle with a conventional frame formed by two rings connected along the upper side by a bridge It is configured to be connectable and fixable to the front part. More specifically, this attachment is also formed from two rings connected to each other via a bridge, and is associated with one end which essentially comprises a gripping part with a clip or a flexible catch. It has a fixing mechanism that stops. More specifically, the clip bends slightly over the bridge when the attachment portion is attached to the front of the spectacles, whereby the front bridge of the spectacles extends along the inside of the hook portion in the seat. And kept pressed against the locking point that cooperates with the hook.
[0012]
Finally, a system for exchanging lenses applied to spectacle frames is also described in US Pat. No. 6,325,506 (Cooper). In this case, an arcuate member that supports both the attachment portion and the glasses is provided. Specifically, this arcuate member is also provided with a lever-type flexible grip portion that acts against the action of a spring corresponding to the bridge. On one side of the arcuate member, an attachment is attached to the corresponding male-female fastener along the outside of the arcuate member. In addition, the grip portion is disposed so as to straddle the bridge corresponding to the intermediate depression between the two protective surfaces, and is configured to be able to grip and hold both lenses at the front of the spectacles by both ends thereof. .
[0013]
To summarize the above configuration, the following configuration is a well-known technique. That is,
An arcuate structure and arm for supporting the lens holder,
A lens holder made of wire, wherein the wire surrounds at least part of the outer edge of both lenses;
A device with a flexible actuation mechanism used to connect the lens holder to the arcuate structure and does not require the use of screws;
The flexible device is arranged in a bridge connecting the two arcuate parts constituting the arcuate structure;
[0014]
[Problems to be solved by the invention]
Disadvantages There are various drawbacks to the solution described above.
[0015]
In the solution configuration by connecting the frame or the main attachment part to the visor, it is difficult to sufficiently fix the lens. In fact, there is significant play to the frame even if they are subjected to the action of a clip that overlaps along the outer part or the action of a magnet.
[0016]
In such a situation, if the glasses are slightly twisted along the front axis, for example, a lens drop occurs.
[0017]
This can cause lens damage or even lens loss if the lens falls or if they fall on a rough surface.
[0018]
As far as similar solutions are concerned, implementing them requires extremely complex work steps, and sometimes requires holes, welding or bonding. Nevertheless, even in such a case, the frame is sensitive and must be handled with great care.
[0019]
Comparing all these solutions, they are basically a complex mounting structure that uses a large number of parts and small parts, which can streamline the assembly process in addition to the heavy structure. Clearly, this is not possible, thereby significantly increasing manufacturing costs. In short, they make it difficult to manage a large number of coded items at the assembly and storefront.
[0020]
The object of the present invention is therefore to clarify an ideal solution for spectacle frames.
[0021]
[Means for Solving the Problems]
Summary of the Invention According to the characterizing features of the appended claims, these and other problems are solved by the present invention by solving the above-mentioned problems.
That is, the eyeglass assembly according to the present invention is

[0031]
These and other advantages will be apparent from the following detailed description and accompanying schematic drawings of at least one preferred embodiment of the present invention, by way of example and not limitation.
[0032]
DETAILED DESCRIPTION OF THE INVENTION
Detailed Description of Various Embodiments Referring to the drawings, in a preferred embodiment of the present invention, a lightweight spectacle structure is provided, which is connected to an arcuate structure 2 and is a lens holder that locks in the middle. 1 is comprised.
[0033]
In the first embodiment, the lens holder 1 comprises a molded continuous flexible metal profile, which is in the form of a closed ring and is configured to fix the periphery along substantially the entire circumference of each lens of the glasses. Has been. Referring to the shape of the lens holder 1, this forms two left and right rings 11 that are connected to each other by an intermediate portion 10, and this intermediate portion forms a connection bridge between the rings 11. Yes. As a result, in this case, each of the left and right lenses is held by the same lens holder 1. Furthermore, in the intermediate part 10 of the lens holder 1, corresponding to the connection bridge between the two rings of the lens holder, the profiles are close to each other to form an appropriate distance between the two lenses held. , 100 and 101, there is a substantially parallel part in the profile formed. As a result, the tension applied corresponding to the bridge 10 and acting to draw the two parts 100, 101 of the profile towards each other is adjusted to securely grip both lenses around their circumference. . By reducing this tension, the lens can be exchanged.
[0034]
Corresponding arcuate frames 2 can be attached corresponding to the bridges 10 of the lens holder 1. In particular, the arcuate frame 2 is formed by one bar, the bar is made of metal in the embodiment. The arcuate frame 2 is shaped so as to form two arcuate left and right mirror image arcuate parts 20 and 21, and the two parts 20 and 21 are held by a lens holder 1 located below. Corresponds to each lens. The two portions 20 and 21 are connected to each other by connecting portions 22A and 22B, and the connecting portions 22A and 22B are also part of a wire to form a saddle clip (an example of a clip portion) if necessary. It is integrally formed by locally folding and folding back. The saddle clips 22A and 22B formed in accordance with the development corresponding to the respective ends of the two mirror image arcuate portions 20 and 21 are formed as follows. That is, by bending the center of the arcuate frame 2, the first portion 220 extends downward. By subsequent folding, the second portion 221 extends toward the inside of the glasses substantially perpendicular to the first folding. Further, the first bent portion is bent in a substantially opposite direction and transferred to form a third bent portion 222. And, finally, to close the Sado torque lip, the fourth bent portion 223 is formed by bending perpendicularly to the third bent portion 222.
[0035]
As shown in FIGS. 1 and 2, in the first example 22A of the saddle clip, the hook portion formed by the portions 221, 222, and 223 faces the inside of the eyeglass structure. On the other hand, as shown in FIGS. 3 and 4, in the second example 22B of the saddle clip, it faces outward.
[0036]
In both cases, when attaching the lens holder 1 to the arcuate frame 2, the flexible parts 222, 223 are first opened to insert the parallel parts 100 and 101 of the profile into the saddle, and then the lens. The saddle clips 22A and 22B are securely attached to the connection bridge 10 of the lens holder 1 by pulling the holder and returning the two parallel parts 100 and 101 of the profile back to their original positions. This is very important.
[0037]
In one preferred embodiment, the connection between the arcuate frame 2 and the lens holder 1 is further improved by using a tooth 12 provided only for the upper part 100 of the bridge 10. In this case, a short member welded onto the main part of the upper profile 100 is present in the upper profile. In this embodiment, in order to lock the lens holder 1 to the arcuate frame 2, the portion 223 of the arcuate frame 2 is pressed against the toothed portion 12 of the holder.
[0038]
In yet another embodiment, the saddle clips 22A, 22B formed by the bars are again relative to the continuous profile of the lens holder 1, corresponding to the intermediate connection between the two support rings for both lenses. It can be formed in a reverse shape that engages from above and below.
[0039]
In the above-described example, the materials used to form the arcuate frame 2 and the lens holder 1 can be different materials such as metal and plastic, and these can be sheared, milled, lasered. It can be formed by cutting or other processing methods.
[0040]
Finally, the nose pads 3 and 4 can be attached by welding in the vicinity of the saddle clips 22A and 22B, for example. Alternatively, they can be connected to a conventional position of the lens holder 1.
