Description

[0001] The present invention relates to a focus adjustable spectacle lens frame,

[0001] The present invention relates to a focus adjustable spectacle lens frame, and more specifically, by changing a focal length of a lens frame through a spectacle lens frame deformed by a coupled lens, the shape and size of the spectacle frame can be varied, And a focus adjustable spectacle lens frame for selecting a spectacle frame so as to be able to vary the focal distance of the lens and the design own face of the spectacle frame.

Generally, the eyeglasses are composed of a spectacle lens frame for fixing the lens, a nose bridge for fixing the spectacle lens frame to the wearer's face, and a pair of eyeglasses frames. The eyeglass frame and the spectacle lens frame are hinged together, It is possible to fold and fold, which makes it convenient to carry and store.

The above-described glasses are worn to complement myopia and myopia. They are used to protect my eyes from harmful rays like sunglasses, and in recent years, they are also used as fashion accessories that show individual personality.

Therefore, glasses should have aesthetic elements in addition to their functional elements, but in recent years, consumers who buy glasses have often opted for glasses rather than the functional elements of the glasses. As such, The functional element is frequently sacrificed.

In other words, not only the face type and size of wearer wearing glasses are different but also the distance between both eyes is different, so that the focus of both eyes can not be the same.

Therefore, the wearer of glasses wears his / her face shape and glasses suitable for the viewing angle, but since the mass-produced spectacle frame can not accommodate the needs of each wearer of glasses, the size of the spectacle frame is simply divided into large, small, And the spectacle wearer can not select his or her face type and the spectacle frame that fits the focus of the field of view. Therefore, the spectacle lens of the size that is closest to the position of the spectacle lens is selected. The focus of the spectacle lens is the eccentricity of the lens, It is the fact that we match.

Therefore, even though wearing eyeglasses to compensate for the purpose of eyeglasses wearers, spectacle wearers are not able to vary the specifications of eyeglass frames. Therefore, there are restrictions on the selection of eyeglass frames by optical factors such as focal lengths of both eyes. The optics required by spectacles are a basic requirement for the wearing of spectacles by focusing on the design of the spectacle frames and developing and supplying the spectacle frames so that the spectacle manufacturer will also select the spectacle It is a fact that it is overlooked.

Therefore, since the spectacle lens frame and the eyeglass legs are mainly exposed to the outside, the design of the spectacle lens frame and the eyeglass legs has been remarkably developed, and various glasses design, color and decoration have been proposed, but glasses based on optical elements have not been proposed .

Patent Document 2: Japanese Patent Application Laid-Open No. 2000-0024274 discloses a configuration in which the optical element such as a focal point of a binocular lens is different from that of a patent but has a structure that prevents damage due to an external impact, And an eyeglass frame in which two eyeglasses (10) are inserted and fixed to the eyeglass frame (10) is formed for the purpose of proposing an eyeglass frame in which allergies are prevented from occurring in contact with the eyeglasses A nose pad 14 mounted on an inner side of a portion where the eyeglass frame body 12 is connected to the eyeglass frame body 12 to restrict the eyeglass frame body 12 from moving downward due to its own weight, And an eyeglass leg 16 provided with a spectacle hook 18 which is extended and projected outward on one side of the eyeglass frame 18 and fixed to the user's ear at the free end thereof. The frame body 12 and the eyeglass legs 16 are made of silicone so that the frame can be freely deformed in a desired shape. This can deform the shape of the lens to meet the optical elements required by the glasses user, The deformed shape of the urethane material freely can not maintain the curve required by the glasses, that is, the angle of deflection along the wearer's face, and the shape of the spectacle frame is changed by the spectacle lens, There is a problem in that the shape of the eyeglasses is poor.

SUMMARY OF THE INVENTION The present invention has been made to overcome the above-mentioned drawbacks of the prior art, and it is an object of the present invention to provide an eyeglass frame which can be fitted to a wearer in accordance with a face- And an object of the present invention is to provide a focus adjustable spectacle lens frame in which the size can be finely adjusted so that the focus can be adjusted to the wearer of the eyeglass.

In order to achieve the above object, the present invention provides a fixing part for restricting the deformation by forming the lens fixing rim constituting the lens frame with a small width and a bridge part with a larger left and right width than the upper and lower thickness widths of the lens fixing rim The upper and lower sides of the lens fixing rim connecting the fixing portions of the mimi and the bridge side are constituted by variable portions having elasticity by increasing the widths before and after the upper and lower thicknesses of the lens to adjust the left and right or top and bottom widths of the combined lens. So that they can be combined with each other.

According to the present invention as described above, the upper and lower widths, the left and the right widths of the spectacle wearer's face and the focal lengths of both eyes are adjusted to couple the processed spectacle lens to the lens frame, There is an effect that it is possible to obtain a focus adjustable type eyeglass capable of focusing the center focal point of the spectacle lens and the focus of the wearer of another eyeglass.

In addition, since the distance between the glasses legs coupled to both sides of the spectacle lens frame is adjusted by adjusting the left and right widths of the spectacle lens, there is an advantage in that it is possible to obtain customized glasses that can adjust the size of the spectacle have.

That is, the present invention is characterized in that the minute fixing portion (13) and the bridge side fixing portion (13) are integrally formed on both sides of the lens fixing rim (A1) constituting the spectacle frame (A) The upper and lower sides of the lens fixing rim A1 constituted by the fixing portion 12 and the fixing portions 13 and 12 on the mimi and bridge sides are formed by the upper and lower variable portions 14 and 15 The upper and lower variable portions 14 and 15 are configured to have an elasticity upward and downward and to be varied by increasing the widths 6 before and after the upper and lower thicknesses 5, respectively.

That is, according to the present invention, the shape of the lens fixing rim A1 can be changed according to the shape of the spectacle lens to be coupled, so that the upper and lower variable portions 14 and 15 increase the front and rear thickness widths 6, It is prevented that the rim A1 is changed before and after and the upper and lower thickness widths 5 are made thin, so that the upper and lower ridges A1 have elasticity upward and downward and can be easily bent.

In the meantime, the present invention as described above is provided with a template of various sizes for processing the outer periphery of the spectacle lens together with the spectacle frame (A).

That is, the template is formed by processing the periphery of the lens along the outer periphery of the template when the spectacle lens is processed. As shown in (b) of the reference template 4 shown in Fig. 6 (a) And a left and right enlarged template 42 that enlarges the left and right widths of the reference template 4 as shown in the small template 41 and the template 40 in FIG.

That is, in the invention, the template is the same as the shape of the spectacle lens. When the left and right magnifying type spectacle lenses are combined with the lens fixing rim A1 of the present invention, not only the width of the spectacle frame but also the focus of the lens is widened. When the spectacle lens is combined with the small spectacle lens, the width of the spectacle frame becomes small and the focus of the lens becomes narrow.

In order to facilitate the understanding of the present invention, the template as described above is briefly described as a left, right and rear small and right and left enlargement type. However, when the left and right enlargement and reduction widths are finely standardized, And focus standards.

In the above, the left and right reduced and enlarged templates have the same circumferential length.

Therefore, the left and right reduction type will expand its width up and down, and the left and right enlarged type will have its width reduced up and down.

That is, according to the present invention, the spectacle lens having the same outer circumferential length is enlarged to the left and right and the upper and lower sides are reduced to obtain the eyeglass frame having the enlarged left and right widths and focal lengths. , A frame having a narrow width and a narrow focal length can be obtained.
