Interchangeable Lens Glasses {LENS EXCHANGEABLE GLASSER}

The present invention relates to a lens interchangeable eyeglasses, and more specifically, to the spectacle lens for eye sight supplementation, as well as to the sunglasses frame for UV protection, so as to eliminate the inconvenience of eyewear wearers The present invention relates to the provision of interchangeable lens glasses for use by the normal public.

In general, eyeglasses are worn by people with myopic or primary and non-myopic eyes with lower vision than normal eyes due to abnormalities of the lens that are responsible for focusing eyes. Due to various inconveniences in everyday life is a common case.

For example, if you want to wear sunglasses that are spotlighted as a fashion item while protecting your eyes from UV rays, you should wear sunglasses without wearing glasses or wear sunglasses while wearing eye-correcting contact lenses. This follows.

In order to alleviate this inconvenience, glasses have been developed and used to allow the wearer of the glasses to wear sunglasses conveniently. Looking through the patent literature as follows.

Document 1 is a sunglasses that can be worn on the glasses including a pair of spectacles body with a pair of spectacle lenses, and a pair of spectacles legs respectively connected to both ends of the spectacle body,

Sunglasses body is coupled to the color lens and the glasses body is accommodated; A pair of sunglasses legs respectively connected to both ends of the sunglasses body and worn on both ears when worn; And an anti-shake means for preventing shaking when the glasses body is accommodated. The sunglasses body includes a lens unit coupled with the color lens to prevent detachment, and a cover unit protruding along an edge of the lens unit. The anti-shake means includes an elastic bending unit detachably provided in the cover part to be bent in the color lens direction by contact with the eyeglass body and to press the eyeglass body in an up and down direction by an elastic force. It is characterized by.

Document 3 is a film; A main frame having a bar shape in which the film is inserted; A coupling member coupled to both end portions of the main frame; And a clip for glasses that can be fastened to the coupling member; It includes, The clip for the glasses is coupled to the upper mounting method on the glasses legs, the film is a flexible PET film, the center of the lower portion is formed in the nose hanger groove that can be fitted to the nose of the human body, The lower surface of the main frame is provided with a plate-like support piece protruding downward to support the film from one side, the support piece is recessed in both sides of the side in the horizontal direction inward, the elongated protrusions on both lower surfaces in the vertical direction Each of them protrudes in an oblique form, and the center of the lower surface is recessed inward.

(Document 1) Utility Model Registration No. 20-0483592-0000 (Document 2) Patent application No. 10-2016-0052582 (Document 3) Patent No. 10-1808415-0000

None.

In the case of the literature 1 of the prior art as described above, when wearing sunglasses on the outside while wearing the glasses to catch the phenomenon such as shaking while preventing the separation of the glasses and sunglasses to the anti-shake means further provided in the sunglasses In the case of Document 3, it can be confirmed that the sunglasses frame can be detached from the outside of the glasses.

As such, in the prior art, eyewear wearers should always be wearing glasses so that the emphasis is placed on the ability to easily attach or detach sunglasses to the glasses without intermittently changing the glasses. .

For this reason, it is always a separate configuration because the sunglasses are coupled to the outside of the glasses as if they were wrapped around the glasses, or the sunglasses and the frames or legs of the glasses could be combined and separated using clamps or magnets. The disadvantage is that you need sunglasses.

For example, no matter how lightweight the sunglasses are, it is necessary to have a sunglasses frame and a sunglasses frame to keep the lens.In case of attaching it to the glasses, it is difficult for the wearer to wear it for a long time because a considerable weight is transmitted to the face part. Becomes

In order to attach the sunglasses to the glasses, the glasses and the sunglasses are provided with separate fixing means, or the coupling plate for accommodating the magnets on the frame, such as the configuration of a separate and distinct from the configuration of the typical glasses frame, There are problems such as complicated manufacturing and assembly process of the frame and cost increase such as cost.

In particular, since the spectacle lens and the sunglasses lens are mounted in a separate structure, spherical aberration may occur between the spectacle lens and the sunglasses lens, which may adversely affect the wearer's vision. Due to the formation of a double coupling structure and a separate additional configuration, the weight of the glasses itself is significantly increased, and wearability is deteriorated. Various problems are occurring.

Accordingly, the present invention has been invented to solve the above problems, by connecting the legs 103 to both sides of the spectacle frame 102 formed with a lens hole 101 so that the lens can be mounted to the spectacle body 104;

The lens hole 101 is further provided with a lens replacement means 110 to be used in combination with the eyeglass lens 105 for the sun protection lens 106 and the sun protection lens 106 to be used as eyeglasses;

The lens exchange means 110 includes a lens groove 111 formed in the inner diameter surface of the lens hole 101 constituting the spectacle body 104;

A lens guard 112 mounted on the lens groove 111 to combine the spectacle lens 105 and the sunglasses lens 106 to be used as spectacles, sunglasses or sunglasses;

A plurality of corrugated protrusions 113 formed on an outer surface of the sunglasses lens 106 to be used in combination with a lens groove 111 or a lens guard 112;

A notch part 125 formed at one or more places of the spectacle body 104 to expand the inner diameter part of the lens hole 101 to facilitate coupling and detachment of the lens guard 112;

Its simple structure makes it possible to quickly change to glasses and sunglasses for both glasses, and to secure the front watch stably by preventing spherical refraction change and blocking the inflow of foreign substances from the outside. It is possible to achieve the purpose.

The present invention by replacing the spectacle lens as well as the sunglasses lens to the lens frame constituting the glasses by replacing the sunglasses function without burdening the wearing of the glasses even if the user's wearing feeling or weight increase due to weight increase By avoiding it has the effect of increasing the convenience of users.

The present invention is to replace only the lenses in the glasses frame to function as glasses and sunglasses, and to narrow the distance between the spectacle lens and the sunglasses lens as much as possible to minimize the refraction change due to the aspherical difference, to solve the instability, the lens and the lens It is an invention having a variety of effects, such as to eliminate the poor visibility due to the inflow of foreign matter.

Lens interchangeable eyeglasses 100 to which the technique of the present invention is applied are connected to both sides of the spectacle frame 102 in which the lens hole 101 is formed so that the lens can be mounted thereon, and the eyeglasses are foldable. 104 is provided.

In the lens hole 101, only one or two lenses may be selected or combined as necessary, such as a pair of eyeglass lenses 105 and a sunglasses lens or a polarization lens (hereinafter referred to as sunglasses lens) 106 for UV protection. The lens exchange means 110 is further determined so that all of them can be used in combination.

The eyeglass body 104 is not limited to a specific material because any one of metal, non-ferrous metal or plastic material may be used, and the lens body 104 may be made of the same material as that of the lens replacement unit 110 or the eyeglass body 104. It will be able to be carried out in a variety of ways, such as to constitute a material in conflict.

The lens replacement means 110 forms a lens groove 111 formed in the inner diameter surface of the lens hole 101 constituting the spectacle body 104, and the lens groove 111 has a sunglasses lens when used as sunglasses only. In combination with the use of 106, the wearer of the eyeglasses if you want to use as sunglasses or only to use the eyeglasses lens lens 112 that can be equipped with a spectacle lens 105 and sunglasses lens 106 It is equipped with.

A plurality of corrugated protrusions 113 are formed on the outer surface of the sunglasses lens 106 to be mounted directly on the lens groove 111 and to be mounted on the lens guard 112.

The degree of protrusion of the corrugated protrusion 113 is equal to or slightly smaller than the depth of the lens groove 111 or the thickness of the lens guard 112 to couple the sunglasses lens 106 to the lens groove 111 and the lens guard 112. When the waveform protrusion 113 is not visually exposed so as not to harm the appearance.

The lens guard 112, the coupling rim portion 116 protruding in the same shape as the lens groove 111 to form a sunglasses lens groove 115 on the inner surface and the lens groove 111 on the outer surface, While forming integrally with the coupling rim 116, the inner surface is formed by forming a spectacle lens rim 118 formed with a spectacle lens groove 117 to couple the spectacle lens 105.

The sunglasses lens groove 115 has a wave shaped protrusion groove (or a wave shaped protrusion hole 119) having the same shape at the same position as the wave shaped protrusion 113 formed on the sunglasses lens 106 to form the sunglasses lens 106 as a lens guard ( 112) to keep it in place.

The outer surface of the spectacle lens rim 118 may be naturally seated on a flat horizontal piece 120 formed on the inner side (the face direction of the wearer) of the lens groove 111 formed in the spectacle frame 102, the coupling The rim portion 116 is preferably coupled to the lens groove 111 to maintain a height that is not exposed to the outside so as not to be visually confirmed from the outside so as not to harm the aesthetics.

The distance between the sunglasses lens groove 115 and the glasses lens groove 117 is within 1 mm, preferably to minimize the space between the glasses lens 105 and the sunglasses lens 106 to prevent the inflow of foreign substances while the glasses legs ( It is good to be able to exclude the field of view failure due to the change of spherical refraction of 105).

Notches 125 are formed in one or more places of the spectacles 104 to extend the inner diameter of the lens hole 101 to facilitate coupling and detachment of the lens guard 112. .

The notch part 125 is formed in a thick portion of the spectacle body 104 so that the spectacle body 104 is not torn or deformed even during frequent operation, and is formed on the inner side rather than the outer side to be visually exposed. 100) It is good not to damage the whole aesthetics and appearance.

The notch 125 may have a variety of shapes. As illustrated in the drawings of the present invention, the notch 125 may have various shapes such as a triangle, a semicircle, and the like, and the thickness of the lens guard 112 may vary. Although thin, it may be formed in the lens guard 112 to provide ease of coupling and separation of the spectacle lens 105 and the sunglasses lens 106.

When the spectacle body 104 is made of a metal material, rather than forming the notch 125 to facilitate the coupling and disassembly of the lens guard 112, the spectacle body 104 is intermittently bolted and released. It may be configured to facilitate the coupling and disassembly of the lens guard 112 by configuring a structure that can be opened and closed.

In the present invention has been described as coupling the spectacle lens 105 and the sunglasses lens 106 to one lens guard 112, as another example, two lens grooves 111 are formed in the spectacle body 104 and the lens The guard 112 may be composed of two for the spectacle lens and the sunglasses lens to be combined and separated to use.

Looking at the state of use of the interchangeable-lens eyeglasses 100, the technique of the present invention as described above are as follows.

First, in order to use as glasses, after coupling the spectacle lens 105 to the spectacle lens groove 117 formed inside the lens guard 112, the lens guard 112 is a lens hole 101 of the spectacle body 104 When combined with the lens groove 111 formed in the) glasses are completed, so the user can wear.

In addition, when the user wants to use the sunglasses while wearing the glasses, the lens guard 112 is separated from the spectacle body 104, and then the sunglasses lens 106 is further added to the sunglasses lens groove 115 of the lens guard 112. After the coupling, the lens guard 112 is coupled to the spectacles 104 again, thereby enabling use as sunglasses.

As another example for use as the sunglasses, in the case of a user who does not wear glasses, the lens guard 112 is completely separated from the eyeglass body 104, and then the sunglasses in the lens groove 111 of the eyeglass body 104. Only lens 106 may be combined to be used as a general sunglasses.

Of course, when the wearer has a sunglasses function, the lens guard 112 is used to combine both the spectacle lens 105 and the sunglasses lens 106, sunglasses lens groove formed in the lens guard 112 ( In the 115, since the corrugated protrusions 119 are formed at the same number and at the same position as the corrugated protrusions 113 formed on the outer surface of the sunglasses lens 106, it is natural to ensure that the sunglasses lenses 106 are normally engaged. something to do.

In addition, when the sunglasses lens 106 is directly coupled to the lens groove 111, the waveform protrusion 113 formed on the outer surface of the sunglasses lens 106 is inserted into the lens groove 111, so that the sunglasses lens ( The phenomenon that the 106 is separated is eliminated, and the boundary points of the corrugated protrusion 113 and the sunglasses lens 106 body are located in the lens groove 111, so that the corrugated protrusion 113 is not visually exposed, thereby aesthetics of the aesthetics. The phenomenon causing trouble such as hatching is eliminated.

When the lens guard 112 is coupled to the spectacle body 104 with the spectacle lens 105 and the spectacle lens 106 coupled to the lens guard 112 using the technique of the present invention, the lens guard The engaging rim 116 protruding from the outer surface of the 112 is coupled to the lens groove 111 to form a shape to maintain the whole.

And, the eyeglass lens rim unit 118 combined with the spectacle lens 105 is seated on a flat horizontal surface 120 formed inside the lens groove 111 to be intermittent by the spectacle body 104, so the lens guard 112 ) Will be able to maintain a stable state continuously.

By selectively combining the spectacle lens 105 and the sunglasses lens 106 in the lens guard 112 as described above to enable the use of glasses and glasses combined sunglasses and sunglasses alone, as well as the lens guard 112 the spectacle body In the process of coupling to and separating from the 104, the lens hole 101 is extended by the notch portion 125 further formed on the spectacle body 104, so that the lens hole 101 can be easily separated and combined.

Particularly, the spectacle lens 105 and the sunglasses lens 106 coupled to the lens guard 112 achieve a close contact or maintain a minute spacing so that the spherical surface of the spectacle lens in the process of using as a pair of sunglasses sunglasses Since the refractive change can be minimized and there is almost no space between the spectacle lens 105 and the sunglasses lens 106, foreign matters and the like can be excluded.

For this reason, it is possible to prevent the phenomenon of unstable expansion of the front watch due to refraction or foreign objects during the process of wearing it as glasses or paired sunglasses. Since it can be used as a combination sunglasses, there is almost no weight increase, which can improve the user's wearing comfort.

The present invention can be easily changed to glasses and sunglasses combined with a simple structure, and can secure the front clock stably by preventing spherical refraction change and blocking foreign material inflow from the outside, and the user's wearing comfort through light weight It has various advantages such as to make it excellent.
