Description

Eyeglass lens positioning structure

The present invention provides a spectacle lens positioning structure, which mainly combines the orientation of the lens set in the eyeglass frame, and the lens can be restricted only by the orientation of the spectacle frame in the middle section, and not on both sides of the lens. The restricted free state, as the glasses incorporated into the lens, does not affect the original optical lens curvature design even if the eyeglass frame is supported by the human head on both sides of the eyeglass frame.

According to the glasses, the glasses combined with the optical lenses of various types are generally included: a frame of a preset shape, a lens of a wide width, and a pair of temples pivoted on both sides of the frame; wherein the lenses are in the group The lens frame is usually formed by extending a convex portion on both sides of the lens, and a middle portion forming a neck portion, so that the convex portions of the lens can be correspondingly placed into the corresponding concave spaces of the outer frame of the eyeglass frame, and the middle portion The neck is in contact with the upper and lower preset spaces of the corresponding sections of the eyeglass frame, so that the sides and the middle of the lens are spaces limited to the corresponding parts of the eyeglass frame, forming an orientation fixing.

Although the arrangement of the optical lens and the eyeglass frame can be conveniently positioned, when the person wears it as a general person, since the human head is inserted into the eyeglasses of the pair of glasses and the eyeglass frame at the front end, the pivotal connection will be The eyeglasses and the eyeglass frame are slightly externally supported, so that the optical lens combined between the eyeglass frames is slightly supported on both sides, and the curvature of the original optical lens is changed.

The creator of the case further improved the arrangement of the optical lens and the eyeglass frame to enhance the preset optical curvature of the optical lens after being incorporated into the eyeglass frame.

The creation of the lens is improved according to the curvature of the optical lens existing in the lens frame which is combined with the lens frame, so that the lens set in the frame between the lens frame is combined in orientation, and the lens can be used. Only in the middle paragraph is limited by the orientation of the eyeglass frame, but Both sides of the lens are in an unrestricted free state. When the glasses are incorporated into the lens, even if the eyeglass frame is flanked by the human head on both sides of the lens, the optical curvature of the original lens is not affected.

The main purpose of this creation is to ensure that the lens frame that is combined with the lens frame can maintain the curvature of the preset lens when in use: in the middle part of the eyeglass frame, a piece of accommodation space is protruded forward, and the outer layer is pre-planned on both sides. An area is provided for the lens to be pushed outward into the two sides of the eyeglass frame, so that the neck of the middle section of the lens can be cut into the receiving space of the corresponding part of the eyeglass frame, so that the lens is limited only by the orientation of the eyeglass frame in the middle section. There is an unrestricted free state on both sides. As the glasses combined with the lens are worn on both sides of the frame, the curvature of the original optical lens is not affected.

The second purpose of the present invention is to place the lens incorporated into the spectacle frame on the lower side of the neck portion of the middle section as a slightly concave arc portion, so as to facilitate the neck of the lens to cut into the corresponding space of the spectacle frame. The arc portion on both sides of the neck can be placed on the bottom surface of the accommodating space to form a proper orientation.

The third object of the present invention is that the area on both sides of the eyeglass frame that is incorporated into the lens must be sufficient to keep the lens in the forward orientation and not to move back into the frame.

The eyeglass lens positioning structure of the present design [as shown in the first figure] is mainly for the eyeglass frame 1 which can maintain the curvature of the preset lens when the lens 2 incorporated into the eyeglass frame 1 is in use, including the eyeglass frame 1 and the lens 2 Composition. Wherein; an eyeglass frame 1 is pivotally connected to the temple 3 on both outer sides thereof, and a receiving space 11 is protruded forward in the middle portion of the eyeglass frame 1, and the outer layer on both sides of the eyeglass frame 1 is Set an area 12.

a lens 2, which is a preset lens according to the shape of the eyeglass frame 1 In the middle section of the lens 2, a neck portion 21 is formed, and the lower periphery of the neck portion 21 is a slightly concave and inward-shaped arc portion 23, and on both sides of the lens 2 is a frame according to the eyeglass frame 1. The outer section 12 is provided with a perimeter 22 in a conforming form.

The above-mentioned lens 2 is arranged in combination with the eyeglass frame 1 (as shown in the second figure), the lens 2 is first pushed outwards into the two side regions 12 of the eyeglass frame 1, and then the neck of the middle section of the lens 2 is made. The portion 21 cuts into the accommodating space 11 of the corresponding portion of the spectacles frame 1 , and straddles the two side arc portions 23 of the pleated neck portion 21 on the bottom surface 13 of the accommodating space 11 to form a proper orientation and hold the lens 2 Only in the middle section is limited by the orientation of the eyeglass frame 1, and there is an unrestricted free state on both sides (such as the third figure).

When the glasses 4 of the lens 2 are combined for wearing (such as the fourth figure), the sides of the eyeglass frame 1 and the temples 3 can be externally supported by the human head, and the two sides of the lens 2 are not Limited free state without affecting the original optical lens curvature.

Claims (3)

The eyeglass lens positioning structure is an eyeglass frame which can maintain the curvature of the preset lens when the lens is used in combination: the middle part of the eyeglass frame protrudes forwardly, and the front side protrudes from the outer layer. In the area, after the lens is pushed outwards into the two sides of the spectacle frame, the neck of the middle section of the lens can be cut into the receiving space of the corresponding part of the spectacle frame, so that the lens is limited only by the orientation of the spectacle frame in the middle section, on both sides It is an unrestricted free state. As the lens combined with the lens is worn on both sides of the frame, the curvature of the original optical lens is not affected. According to the eyeglass lens positioning structure of claim 1, wherein the lens incorporated in the eyeglass frame is located on the lower left side of the neck portion of the middle section as a slightly concave arc portion, so that the neck of the lens is cut into the eyeglass frame. The accommodating space of the corresponding portion enables the arc portion on both sides of the lower portion of the neck to straddle the bottom layer of the accommodating space to form a proper orientation and clamping. According to the eyeglass lens positioning structure of claim 1, wherein the area of the outer frame of the eyeglass frame incorporated into the lens must be sufficient to keep the lens in the forward orientation and not to move back into the eyeglass frame.
