Abstract
More specifically, the present invention relates to an improved lens assembly structure, and more particularly, to an improved lens assembly structure in which a lens is inserted into a hollow structure of a hollow body of a front body made of metal material of non-stretchable material such as duralumin, aluminum, To a metal-based spectacle having an assembled structure.
Description
More specifically, the present invention relates to an improved lens assembly structure, and more particularly, to an improved lens assembly structure in which a lens is inserted into a hollow structure of a hollow body of a front body made of metal material of non-stretchable material such as duralumin, aluminum, To a metal-based spectacle having an assembled structure.
In addition to the function of correcting and protecting eyesight, eyeglasses also function as an accessory which changes the impression of the wearer. Especially, the wearer of the young fashionable eyeglasses wears several glasses with different designs, It is a fact that it wears.
Such spectacle frames have been made of plastic or metal materials, and Korean Unexamined Patent Application Publication No. 10-1999-0068274 discloses an eyeglass frame made of a non-ferrous metal such as aluminum.
The front made of aluminum, which is the non-ferrous metal, is light in weight compared to stainless steel and has a variety of aesthetic sensations due to its inherent texture. In recent years, a front layer made of aluminum material is formed with a coating layer, And a better sense of beauty is achieved through various colors.
On the other hand, the aluminum frame frame includes: an aluminum frame having rims formed at both ends of the bridge; A hinge connector fixed to both ends of the aluminum front; And a leg fixed at both ends of the aluminum front through the hinge connector in a hinge structure.
However, since duralumin, aluminum or titanium is a non-stretchable material which can not be stretched unlike plastic, it is difficult to apply a lens assembly structure applied to plastic glasses which fixes a lens by elastic pressing on a hollow rim formed on a front body.
Accordingly, in the related art, a pair of open ends are vertically spaced from both ends of a hollow rim formed on a front body made of a metal material, and a fastening hole is formed in the opening end so as to pass through the hollow body. A fixing bolt is fastened to the upper and lower fastening holes to close the hollow rim into which the lens is inserted.
The assembly structure of such a lens requires an opening in the hollow rim, which increases the manufacturing cost of the lens. In addition, when the lens is detached, the opening is opened and closed through the fastening bolt. In addition, design constraints arise due to the formation of the openings and the formation of fastening bolts to close them.
Particularly, the non-ferrous metals such as aluminum and titanium constituting the front are low in hardness, so that when physical deformation occurs in the fastening portion due to repetitive fastening, the closed state between the opening ends through the fastening bolt becomes poor , Especially when the clearance between the upper and lower open ends is generated and the rim is distorted, the fastening force between the fixing bolt and the aluminum front is weakened and it is difficult to secure stable durability.
SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems. In the present invention, in inserting and fixing a lens into each hollow rim formed on a front body made of a non-stretchable metal material such as duralumin, aluminum or titanium,
It is possible to fix the lens by inserting the lens into the hollow rim without opening and closing the hollow rim through the opening and closing of the hollow rim when the lens is inserted. Especially, the edge of the lens inserted in the hollow rim is directly attached to the hollow rim Thereby preventing the phenomenon that the lens inserted in the hollow rim is prevented from being detached by an external force due to the fixed fixing of the lens, thereby providing a metal eyewear having an improved lens assembling structure have.
The above object is achieved by the following constitutions provided in the present invention.
In the metal eyewear having the improved lens assembling structure according to the present invention,
A front body having a hollow rim formed on both right and left sides and made of a metal material; And a lens inserted and fixed in an inner diameter of each hollow rim formed on the front body,
Wherein each of the hollow rims of the front body is provided with a solid support band formed of a front body of a metal material and a plastic material of a release material and formed with a press-fit groove for fixing the edge of the lens by elastic press-
The lens having the outer diameter of the press-fit protrusion is elastically press-fitted into a solid support band made of a plastic material, and is fixed to the hollow rim of the front body made of a metal.
Preferably, an inner diameter of the hollow rim on which the solid support band is disposed is formed so as to be recessed into an assembly groove portion, and the solid support band is fixed to the inner wall of the hollow rim while supporting the outer wall thereof.
More preferably, the mounting groove formed in the inner wall of the hollow rim has a shape in which an upright front supporting surface and a rear supporting surface are spaced apart, and is configured to support and support the front and rear surfaces of the solid supporting band,
Wherein an elastic gap portion is formed between the inner diameter surface of the mounting groove portion and the outer diameter surface of the solid support band so that when the lens is inserted into the solid support band, the solid support band is elastically deformed through the elastic air gap portion to elastically press- .
In addition, an arc-shaped cavity groove portion recessed into a curved shape is formed on the outer diameter face of the solid support band facing the inner diameter face of the mounting groove portion, and elasticity of the solid support band between the inner diameter piece of the mounting groove portion and the outer diameter face of the solid support band An elastic air gap portion for deforming is formed,
The solid support band has a V-shaped press-fit groove formed inwardly inwardly of the inner surface between the front and rear ends, and an arc-shaped cavity groove formed inwardly of the outer surface of the solid support band. So that the elastic deforming section is elastically deformed while the elastically deforming section enters the elastic air gap portion when the lens is elastically press-fitted.
In addition, the height of the front end and the rear end constituting the solid support band is relatively higher than the front support surface and the rear support surface of the assembly groove portion accommodating the solid support band, and the solid support band provided in the assembly groove portion is set So as to protrude upward,
The lens assembled in the hollow rim through the solid support band is configured to remain spaced from the hollow rim formed in the front body.
As described above, in the present invention, in inserting and fixing the lenses in the respective hollow rims formed in the front body made of the non-stretchable metallic material such as duralumin, aluminum, titanium, etc., the front body and the release body A solid support band made of a plastic material is disposed so that the lens is easily elastically press-fitted into the closed hollow rim and fixed.
When a lens fixing structure including such a solid support band is provided, the lens can be elastically press-fitted by elastic deformation of the solid support band. Therefore, in the hollow rim of the front body made of the conventional metal material, It is possible to eliminate the operation of arbitrarily opening and closing the hollow rim through the opening / closing end when replacing the lens, so that the manufacturing cost and the simplification and quickness of the operation can be ensured due to the manufacture and replacement of the lens.
Particularly, in the present invention, a solid support band made of a plastic material having a unique structure and shape is disposed in the assembly groove portion of each hollow rim, thereby securing an elastic deforming space of the solid support band between the solid support band and the hollow rim.
Therefore, in the metal-based spectacle according to the present invention, the lens is easily inserted through the elastic deforming of the solid supporting band during the pressing process of the lens, and the lens is stably constrained by the solid supporting band when the lens is inserted , Arbitrary departure due to external force is prevented.
