Description

Spectacles for preventing scratches of lens [0002]

More particularly, the present invention relates to an eyeglass preventive projection for preventing a lens from touching the ground when a front surface of the eyeglasses is placed facing the ground, The lens frame is integrally formed with the lens frame so as to prevent the lens from being scratched so that the life of the lens is prevented from being shortened and the scratch prevention protrusion is reinforced in strength by being integrated with the lens frame by adding the fiber reinforcing material to the polymer resin, The present invention relates to a lens for preventing a lens from being easily broken or broken even when an impact is applied thereto.

Glasses are to be worn on the eye to protect the eyes from bad eyes or to protect the eyes from wind, dust and strong sunlight. The eyeglasses usually comprise a spectacle lens for protecting the eyes or for correcting the visual acuity, an eyeglass frame for supporting the lens for fixing the lens, and a spectacles bridge for supporting the eyeglass frame to be positioned in front of the eye. Such a pair of glasses can be worn on the upper part of the ear by unfolding the glasses leg when worn, thereby facilitating the wearing of the glasses.

The wearer wearing such glasses wears glasses by spreading their glasses legs when the glasses are worn. When the glasses are not used, the glasses are folded and stored in the glasses storage box.

However, since it is troublesome and uncomfortable to store the glasses in the eyeglass storage case when the glasses are stored in the eyeglass storage box, ordinary eyeglass wearers unwittingly take off the glasses and put them on the desk, the table, or the floor.

In this case, if the front surface of the spectacle lens is faced to the ground, or is turned over by external force, and the front surface of the spectacle lens is brought into contact with the ground surface, the spectacle lens will be scratched and visibility becomes difficult to be secured, .

To solve the above problems, Korean Utility Model Registration No. 20-0367316 is disclosed. In the above-described technique, when the spectacles are folded and rotated in multiple angles, the spectacle legs and the spectacles nose fins are folded and rotated so that the spectacle legs on both sides are folded on the front and back sides of the spectacles, So that it is possible to prevent the spectacle lens from being scratched by protecting the spectacle lens.

However, since this technique is required to be made so that the eyeglass legs and the nose support are folded and rotated in multiple angles, the manufacturing cost is high, and the glasses legs and nose supports are folded so as to be located on the front and rear sides of the eyeglass lens, which is troublesome and inconvenient .

On the other hand, the spectacles are produced by bending and welding an alloy material such as a nickel alloy or the like appropriately to form an eyeglass frame, and the eyeglass legs are manufactured using the same material, and then the eyeglass frame and the eyeglass legs are welded by using hinges or by using a synthetic polymer resin material The eyeglass frame and the eyeglass legs are injection-molded, and then they are welded and fixed using a hinge.

However, when the glasses are manufactured using an alloy material such as a conventional nickel alloy, the durability and texture are good and the abrasion resistance is excellent. However, the glasses are poor in moldability, difficult to implement various designs, and have a problem in weight when worn.

Therefore, in recent years, eyeglasses made of synthetic polymer resin materials have been spotlighted. Glasses made of a synthetic polymer resin material are usually produced through an injection mold, so that they are excellent in moldability and can be implemented in various designs. .

Cellulose acetate (CA), which is a representative material of synthetic polymer resin materials used in the production of spectacles, is a material that is different from general-purpose spectacle frames and is comparable to glasses made of other synthetic polymer resin materials. It is able to recover the gloss by polishing without any additional coating process even when scratches occur, and it has been popular as a high-value-added eyeglass material and called " . Therefore, the market share has been steadily growing recently, and interest and demand for CA frames are increasing in Korea.

However, since the conventional glasses made of cellulose acetate material are weak in elasticity due to the characteristics of the cellulose acetate material, when the force is applied from the outside, they are broken without being bent, and the nose marks are left on the nose of the wearer due to the heavy weight, There is a problem that when the lens is worn for a long period of time, the entire glasses are widened and the glasses flow down.

Korean Utility Model Registration No. 20-0367316

In order to solve the above-described problems, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a lens- It is desirable to provide a lens for preventing a lens from being scratched by preventing a lens from being scratched by preventing a lens from being brought into contact with the ground and being spaced from the ground by a predetermined distance .

Another object of the present invention is to provide an eyeglass that reinforces the rigidity of the scratch prevention protrusion by forming a fiber reinforcing material by adding a scratch prevention protrusion to the eyeglass to prevent the scratch prevention protrusion from being easily broken or broken due to an external impact, .

Another object of the present invention is to provide glasses with a high elasticity and light weight polyetherimide material so that the shape of the glasses is not deformed semi-permanently, thereby eliminating the excessive pressure feeling of the glasses made of the conventional cellulose acetate material, thereby providing a more comfortable fit Which is capable of preventing the phenomenon that the glasses flow down at the same time, is prevented.

The eyeglasses that prevent the lens from being scratched according to the present invention are formed in the shape of the lens 110 to which the lens 110 is coupled and are coupled with the end piece 120 to which the eyeglass legs 300 are connected, A bridge 200 connecting the two lens frames 100 and one end rotatably connected to the end piece 120 of the lens frame 100, The lens frame 100 includes a lens frame 100 and a lens frame 100.

Therefore, the definition should be based on the contents throughout this specification.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a spectacle lens according to an embodiment of the present invention, FIG. 2 is a side view of a spectacle lens according to an embodiment of the present invention, FIGS. 4 and 5 are perspective views of spectacles to prevent scratches on the lens according to other embodiments of the present invention. FIG.

As shown in FIGS. 1 to 5, in the present invention, in order to prevent the lens 110 from touching the ground surface and causing scratches when the front of the glasses is placed on the ground surface without wearing glasses, (Hereinafter referred to as "glasses 1") for preventing scratches on the lens having the prevention protrusions 500 formed thereon.

The eyeglasses according to one embodiment of the present invention may include a lens frame 100, a bridge 200, a glasses leg 300, a nose support 400, and an anti-scratch protrusion 500.

First, the lens frame 100 supports the lens 110 by being coupled with the lens 110, and may be formed in various shapes according to the shape of the lens 110 to be coupled. The lens frame 100 is formed to surround the rim of the lens 110, and two lens frames 100 may be provided in front of the wearer's eyes.

The lens frame 100 may be connected by a bridge 200. The bridge 200 connects the two lens frames 100 positioned in front of the wearer's eyes, And the balance of the balance.

The bridge 200 may be formed in an arch shape as shown in FIG. 1 to prevent the prism effect generated by the lens 110 when the spectacle 1 is worn. .

As shown in the drawing, an end piece 120 may be formed on the outer side of each lens frame 100. When the glasses 1 are worn on the end piece 120, The eyeglass leg 300 supporting the frame 100 to be positioned in front of the wearer's eye is connected.

The endpiece 120 may be formed integrally with the lens frame 100 in the case of a screwdriver, which receives a greatest mechanical torque when the glasses 1 are worn.

The eyeglass leg 300 may be connected to the end piece 120 formed on one side of the lens frame 100 while the other side of the eyeglass leg 300 may be bent so as to be engaged with the upper portion of the wearer's ear. At this time, the spectacle leg 300 may be hingedly connected to the end piece 120 to be rotatable.

In addition, the spectacle leg 300 may further include a medical magnet (not shown) for generating a magnetic field in a region beneficial to the human body. The medical magnet may be provided at a portion of the wearer's skin, And is provided inside the curved portion of the eyeglass leg.

The medical magnet stimulates circulation of blood by stimulating the blood in a portion in contact with the skin, and usually has a surface magnetic field of 500 to 5000 gauss such as magnetic force of a magnet used for medical use.

The nose 400 is formed in order to prevent the glasses 1 from flowing down when the wearer wears the glasses 1 and to enhance the comfort of the wearer. The nose 400 is protruded rearward (toward the wearer) of the lens frame 100 on the rear surface of the lens frame 100. At this time, the lens frame 100, which corresponds to the wearer's nose, May be formed on the rear surface.

3, when the lens 110 is placed on the ground so that the lens 110 faces the ground without wearing the eyeglasses 1, the scratch prevention protrusion 500 prevents the lens 110 from contacting the ground And may be formed to protrude from the front of the lens frame 100 (in a direction away from the wearer).

The position where the scratch prevention protrusion 500 is formed is not limited as long as it is a position where the lens 110 is not in contact with the paper surface. Preferably, as shown in FIG. 1, 100a so as to prevent the front surface of the lens 110 from contacting the ground when the front surface of the lens 110 is positioned toward the ground. 1, the inner side 100a of the lens frame 100 is a portion located around the nose of the wearer in the lens frame 100. As shown in FIG.

4 and 5, according to another embodiment of the present invention, the scratch prevention protrusions 500 may be formed only on the outer side portion 100c of the lens frame 100, or may be formed on the upper side 100b and the outer side portions 100c As shown in Fig.

The scratch prevention protrusions 500 may be formed integrally with the lens frame 100. In this case, when the lens frame 100 is injection-molded, the scratch prevention protrusions 500 may be formed The impact resistance of the scratch prevention protrusion 500 can be enhanced by adding aramid fiber or carbon fiber, which is a fiber reinforcing material, to the groove for the scratch prevention protrusion 500.

Aramid fiber and carbon fiber are much stronger than general fiber such as nylon and polyester, have high heat resistance, have very high tensile strength and elasticity, but are light in weight and are used for bulletproof materials and aircraft materials.

Therefore, a high-strength functional fiber reinforcing material such as aramid fiber or carbon fiber is placed in a groove for forming a mold anti-scratching projection 500 for manufacturing the eyeglasses 1 of the present invention, and a molten polymer resin It is possible to form the scratch prevention protrusions 500 by filling the grooves by the injection and enclosing the fiber reinforcing material.

The scratch prevention protrusion 500 formed by adding the fiber reinforcing material as described above has an advantage that the impact resistance is strengthened so that it is not easily broken or broken due to an external impact.

The polymer resin may be a synthetic polymer resin such as nylon or the like, a polyamide-based (e.g., TR-90 system), a cellulose ester, an ABS resin or a silicone rubber, and natural rubber. The cellulose ester system is excellent in adaptability to skin, elasticity, etc. Specifically, cellulose acetate, cellulose acetate butyrate, cellulose acetate propinate and the like can be used. The polyamide-based and ABS-based resins have an advantage of excellent strength and elasticity.

On the other hand, the glasses 1 according to the present invention can be made of a non-crystalline thermoplastic polyetherimide material.

The polyetherimide material is a non-toxic material with excellent heat resistance, dimensional stability, high strength, high elasticity, chemical resistance, crack resistance, anticorrosion and flame retardancy.

Accordingly, polyetherimide materials are utilized in various fields including high-tech industries such as aircraft interior products, food and beverage related products, medical supplies, and kitchen utensils.

The glasses formed of the polyetherimide material are thin and light and have strength and restoring force so that not only the wearing feeling is increased but also the end pieces 120 (120) to which the lens frame (100) and the eyeglass legs Is absorbed by the eyeglass leg 300, so that the eyeglass leg 300 can be opened to prevent the glasses from flowing down.

The spectacle leg 300 connected to the lens frame 100 through the end piece 120 may be thicker than the other side so that the lens frame 100 can be stably supported. At this time, since one side of the spectacle leg 120 is made thicker than the other side, the spectacle leg 300 can be bent more easily.

The bridge 200 connecting the lens frame 100 and the lens frame 100 to which the lens 110 is coupled is made of a cellulose ester material, The spectacle leg 300 coupled to the end piece 120 of the lens frame 100 may be made of a polyetherimide material. At this time, the eyeglass leg 300 may be made entirely of polyetherimide material, or only a part of the eyeglass leg 300 may be made of a polyetherimide material and the remaining part may be made of a cellulose ester material.

The cellulose ester material is not particularly limited as long as it has processability and mechanical properties suitable for the production of the spectacles, and examples thereof include cellulose acetate, cellulose propionate, cellulose butyrate, cellulose hexanoate, cellulose octanoate, Cellulose acetate (CA) may be used alone or in combination (cellulosic fatty acid ester mixed ester), preferably cellulose acetate (CA).

The lens frame 100 and the bridge 200 may be made of a mixture of a cellulose ester material and a polyetherimide material. At this time, 30 to 65 parts by weight of the polyetherimide material may be mixed with 100 parts by weight of the cellulose ester material. If the content of the polyetherimide material is less than 30 parts by weight, there is a problem in that the impact resistance is poor due to insufficient elasticity. If the amount exceeds 65 parts by weight, compatibility with the cellulose ester material and heat fluidity are lowered, .

As described above, the eyeglass 1 according to the present invention, which is made of a mixture of a cellulose ester material and a polyetherimide material, has an advantage in that the elasticity is increased more than that of a conventional eyeglass made of a cellulose ester material, Therefore, when the lens is worn for a long time, the phenomenon that the entire eyeglasses are opened and flowed down can be reduced.

According to the present invention as described above, the scratch prevention protrusions 500 protrude from the front of the lens frame 100 in front of the lens frame 100 so that the wearer unconsciously removes the lens Since the lens 110 is spaced apart from the ground without touching the ground by the scratch prevention protrusions 500 protruding from the lens 110 when the front surface of the lens 110 is placed facing the ground, It is possible to prevent the occurrence of scratches on the lens 110 and to prevent the life of the lens 110 from being shortened.

In addition, since the scratch prevention protrusions 500 are integrally formed with the lens frame 100 with a fiber reinforcement attached thereto, the scratch prevention protrusions 500 are not easily broken or broken even when an impact is applied from the outside.
