Description

Eyewear with interchangeable lenses according to frame separation {EYEWEAR WITH REPLACEABLE LENS ACCORDING TO FRAME SEPARATION}

The present invention relates to eyewear in which a lens can be replaced by separating a frame.

Eyewear is made of a transparent material, and there are general glasses with an adjusted refractive index, but there are also products that protect the user's eyes from glare or ultraviolet rays by lowering the transmittance. Generally used sunglasses are manufactured by adding a colorant to a transparent glasses material or coating or depositing a material that reflects light, so that the user feels less glare or protects the eyes from ultraviolet rays.

In this way, products such as a kind of tinted sunglasses prevent the wearer from being dazzled in a bright place by preventing a large amount of light from being transmitted by a kind of shading lens constituting the sunglasses, or blocking ultraviolet rays to prevent damage to the eyes. It can prevent nerve damage. On the other hand, in addition to the shading lens that controls the amount of light, eyewear with untinted or only slightly tinted lenses is used to prevent wind from being directly transmitted to the user's eyeball or foreign substances such as dust from being transmitted. There are more and more people.

In particular, in the case of sunglasses used for military purposes, sunglasses are used for the purpose of blocking light according to the operation being performed, used for the purpose of blocking ultraviolet rays, or simply used for the purpose of protecting the eyes. Eyewear is used, but it is inconvenient to replace the eyewear for each use (case) or to carry and replace the eyewear for each use.

The lens unit includes a plurality of lenses 300, and the lenses 300 may be formed of a material including polycarbonate (PC), glass, or other resin, but are not limited thereto. In addition, the lens 300 is a detachable type applied to the left and right eyes of the user, and may be inserted and mounted between the upper frame 100 and the lower frame 200 . Also, as will be described later in detail, the lens 300 can be replaced with a different lens after separating the upper frame 100 and the lower frame 200 .

For example, the lens 2300 may prevent glare by lowering the transmittance of a part of the visible ray region of sunlight or protect the user's eye cells from being damaged by blocking light in the ultraviolet wavelength range region. The light-shielding lens may be a polarizing lens that lowers light transmittance, a lens containing a colored dye, or a photochromic lens, and is not particularly limited thereto. In addition, the outer portion of the lens 300 may be hard-coated to prevent scratches or may be subjected to an anti-fog (AF) process, and is not particularly limited thereto. In addition, the lens 300 may be a power lens having a specific power, or may be a lens in a state in which a small amount or almost no colored dye is included without a separate power. In addition, it may be a reinforced lens with enhanced impact resistance. That is, the eyewear of the present invention can be used by replacing various types of lenses as needed.

In the case of eyewear used for military purposes, it is used for various purposes such as being used as sunglasses to block light depending on the operation being performed, to block ultraviolet rays, or to simply protect the eyes from external factors. Eyewear is used accordingly. To change and use the eyewear for each of these purposes (cases), there was the inconvenience of having to carry and replace the eyewear for each purpose, but in the case of the present invention, the lenses can be easily replaced and used, Just having lenses can produce the same effect as having eyewear for multiple purposes.

The upper frame 100 inserts and fixes the upper part of the lens 300 to the upper end of the lens part, and includes an upper insertion part 130 formed as an empty space having a shape corresponding to the shape of the cross section of the upper part of the lens, The lower frame 200 inserts and fixes the lower part of the lens 300 to the lower end of the lens part, and includes a lower insertion part 230 formed of an empty space having a shape corresponding to the shape of the cross section of the lower part of the lens, and an upper part in the center. It includes a fixing part 250 formed to protrude toward. That is, while the lens 300 is inserted into the upper insertion portion 130 of the upper frame 100 and the lower insertion portion 230 of the lower frame 200, the upper frame 100 and the lower frame 200 are By being coupled, it can be firmly fixed to the frame.

The combination of the upper frame 100 and the lower frame 200 can move back and forth while penetrating a part of the center of the upper frame 100, and the fixing part 250 of the lower frame 200 is When inserted into a part of the insertion part 130, the fixing part 250 can be fixed to and separated from the upper frame 100 by the detachable part 400. That is, the fixing part 250 of the lower frame 200 can be inserted into the upper insertion part 130 at the center of the upper frame 100, and is held by the detachable part 400 penetrating the upper frame 100. Thus, the upper frame 100 and the lower frame 200 can be coupled, and the detachable part 400 can be moved again to separate the upper frame 100 and the lower frame 200 .

The lens leg 700 is coupled to both sides of the upper frame 100 and can be folded or folded. The lens leg 700 is used by hanging eyewear on the user's ear, and may be made of a plastic resin material or the like.

On the other hand, the lower frame 200 is curved toward the lower end from both sides from the center so that the plurality of lenses 300 are inserted, and the upper frame 100 extends from the center to both sides toward the upper end to insert the plurality of lenses 300. It can be bent so that it is inserted. That is, while a part of the lens 300 is inserted, the upper frame 100 may be curved upward and the lower frame 200 may be curved downward to correspond to the shape of the lens 300 . Accordingly, after the lens 300 is coupled to the upper frame 100 and the lower frame 200, it can be stably seated in the frame.

In addition, the lower insertion portion 230 is formed toward the user and extends from the first lower sidewall 210 and the first lower sidewall 220 to support a portion of the inner surface of the lens to be inserted, and the inserted lens 300 A lower support surface for supporting the lower surface of and a second lower side wall 220 extending from the lower support surface and facing the first lower side wall 210 and supporting a portion of the outer surface of the lens 300 inserted therein. And, the upper insertion part 130 is formed in the user direction and supports a portion of the inner surface of the lens 300 to be inserted, and the first upper side wall 110 extends from the first upper side wall 110 to be inserted. An upper support surface supporting the upper surface of the upper support surface, and a second upper side wall 120 extending from the upper support surface and supporting a part of the outer surface of the lens 300 inserted while facing the first upper side wall 110 can include

The insertion portion 130 is formed by a space partitioned by the first upper side wall 110 , the upper support surface, and the second upper side wall 120 so that the upper end of the lens 300 can be inserted.

In addition, the lower frame 200 and the upper frame 100 have a convex shape to move away from the user toward the center, and the first lower sidewall 210 has a lower supporting surface than the second lower sidewall 220. The first upper side wall 110 may have a higher height from the upper support surface than the second upper side wall 120 . In other words, when the user wears the eyewear, the lower frame 200 and the upper frame 100 may be curved so that the central portion is curved outward to correspond to the shape of the user's face, and the first lower sidewall 210 may be curved. Since the height of the first upper side wall 110 is higher than that of the second lower side wall 220 and the height of the first upper side wall 110 is higher than that of the second upper side wall 120, it is possible to prevent the lens from escaping toward the user. That is, a kind of support wall is formed in the user direction by the second lower side wall 220 and the second upper side wall 120 to prevent the lens 300 from being separated (falling down) in the user direction while preventing the lens 300 from falling. When replacing, the lens can be easily removed in an outward direction by the user.

In particular, in the case of eyewear used for military purposes, the environment in which it is used is often active, so the lens can be easily removed. As described above, the lens is separated by the second lower sidewall 220 and the second upper sidewall 120 One side of 300 is supported, and lens replacement is easy due to the curved shape of the frame and the curved shape of the lens, but it is possible to prevent the lens from being easily separated when using eyewear.

On the other hand, the upper frame 100 is formed on a surface facing the face of the user wearing the eyewear, and further includes frame elastic lines 115 and 116 formed by being recessed inward, and the frame elastic lines are detachable. A plurality of first frame elastic lines 116 disposed apart from the left and right sides of the part 400 and disposed spaced apart from the first frame elastic lines 116 and arranged with respect to the detachable part 400 to the first frame It includes the second frame elastic line 115 disposed further away than the elastic line 116, and the lens leg 700 is formed adjacent to the upper frame 100 and has an X shape compared to other areas. It may be characterized in that it includes a strength reinforcing portion 117 protruding in a shape.

While reducing the weight of the entire eyewear by the frame elasticity lines 115 and 116, it is possible to impart elasticity to the upper frame 100 of the eyewear, and accordingly, in the process of replacing the lens 300, the upper frame ( 100) can be effectively prevented from being damaged. In addition, by disposing the first frame elastic line 116 and the second frame elastic line 115 apart from each other, it is possible to secure the rigidity of the entire frame while providing elasticity to the entire upper frame 100 . That is, the cross section of the portion where the frame elastic lines 115 and 116 of the upper frame 100 exist by the first frame elastic line 116 and the second frame elastic line 115 can be a kind of U-shaped shape. Accordingly, it is possible to secure frame rigidity while reducing frame weight.

The lens leg 700 is recessed inward and is adjacent to the lens leg elastic line 715 formed in the longitudinal direction of the lens leg 700, and the lens leg elastic line 715, while the upper frame 100 is referenced. It further includes a plurality of reinforcing lines 720 formed at a distance farther than the lens leg elastic line 715 and recessed inward to cross the length direction of the lens leg 700, The reinforcing lines 720 of may be characterized in that they are arranged parallel to each other and spaced apart.

The lens leg elasticity line 715 can secure the elasticity and rigidity of the lens leg 700 while reducing the weight of the entire lens leg 700 . When a user wearing the eyewear of the present invention has a lot of activity, damage to the lens leg of the eyewear can occur relatively easily, but durability can be improved while reducing the overall weight by the elastic line 715 of the lens leg. In addition, since the plurality of reinforcing lines 720 are spaced apart from each other in parallel, the force applied to the lens leg 700 can be dispersed, thereby preventing the lens leg 700 from being damaged more efficiently.
