Description

Spectacles with 2 way sight}

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a spectacle capable of securing a view in two directions, and more particularly, to a reflection spectacle using two or more reflectors.

Recently, as personal communication devices have developed, personal mobile devices such as smart phones are widely used in subways, buses, and even on foot. Since the smart phone needs to be operated by a person's hand, it is located at a lower position than the head of the user, and the user may keep the head bent for a long period of time in order to operate and confirm the smart phone many. When the smartphone is used for a long period of time in such a non-normal posture, it often happens that the neck part becomes uncomfortable, leading to diseases such as a neck disk.

I need a technology that can see smartphones without bending my head. Existing technologies have implemented the ability to view objects (eg smartphones, books, tablets, computers, etc.) It is not possible to do so. In order to view the front, it is necessary to take off the glasses or watch the front vehicle or people or danger when worn.

On the other hand, in recent smart devices, the size of a unit pixel becomes very small according to the development of technology, and accordingly, the amount of information that can be displayed per unit area becomes much larger than the conventional one. On the other hand, conventional products using a method of changing a path of light through a back coated reflector, a prism or a half mirror use a general reflector, so that the image is refracted and a double reflected ghost image is generated.

The present invention provides an eyeglass that allows a viewer to see an object, such as a smart phone, a book, a notebook, and the like, without looking down at the viewer's head.

In addition, the present invention provides a spectacle that can eliminate ghost phenomenon and deterioration of image quality by eliminating double reflection of the reflector, and minimize dizziness when wearing reflective glasses.

The eyeglasses capable of securing a two-directional view according to the present invention include a frame forming an outer shape of the eyeglasses; A first reflector provided at an upper portion of the frame and reflecting light incident from below; And a second reflector provided at a lower portion of the frame for reflecting the light reflected from the first reflector back to the eye side of the human body, wherein the second reflector is disposed between the first reflector and the second reflector, The first reflecting portion and the second reflecting portion are respectively positioned above and below the front viewing angle of the user so that a front view can be secured.

The first reflector and the second reflector may be front reflectors.

The horizontal distance from the first reflecting unit to the user's eye may be equal to or larger than the horizontal distance from the second reflecting unit to the user's eye.

Further, the second reflecting portion may be provided in a viewing angle of 21 to 37 degrees downward from the front of the user.

Also, the second reflector may have a downward inclination toward the user's eye, and the inclination may be about 15 to 25 degrees with respect to the horizontal plane.

The first reflector may be formed to have an inclination of -5 degrees to 5 degrees with respect to a horizontal plane.

Viewing angle

A distance from the eye of the user to the center of the second reflector is K1, a distance from the center of the second reflector to the center of the first reflector is K2, a length of the second reflector is L1, Assuming that the vertical length of the first reflector is L2, the vertical length L1 of the first reflector may satisfy the following expression (1).

[Formula 1]: L1 < = L2 x K1 / (K1 + K2)

The width of the first reflector may be equal to or greater than the width of the second reflector.

Also, the frame may be formed in an integral shape.

Further, the frame includes a pair of eyeglasses legs fixed to an ear of a human body; A first support part connecting the pair of eyeglasses legs and fixing the first reflection part; A pair of extension portions extending downward from both sides of the first support portion; And a second support portion connecting the lower portion of the extension portion and fixing the second reflection portion.

In addition, the first supporting portion, the pair of extending portions, and the second supporting portion may form a view securing through-hole, which is a space penetrated to secure the front view of the user.

In addition, a lens for at least one of visual acuity correction and ultraviolet ray blocking of the user may be provided in the penetration for securing the view.

Further, the horizontal distance from the first reflecting unit to the user's eyes may be smaller than the horizontal distance from the second reflecting unit to the user's eyes.

According to the present invention, it is possible to allow a user to view a lower image using a pair of reflecting mirrors without turning his / her head, and to ensure a forward view through a pair of reflecting mirrors without removing the glasses according to the present invention There is an effect that can be.

In addition, according to the present invention, it is possible to minimize the dizziness due to the ghost image by removing the double images by using the mirror of the front reflection type rather than the mirror of the rear reflection type.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the absence of special definitions or references, the terms used in this description are based on the conditions indicated in the drawings. The same reference numerals denote the same members throughout the embodiments. For the sake of convenience, the thicknesses and dimensions of the structures shown in the drawings may be exaggerated, and they do not mean that the dimensions and the proportions of the structures should be actually set.

1 to 5, a description will be made of glasses capable of securing a two-directional view according to an embodiment of the present invention. 1 is a perspective view showing a state of glasses according to an embodiment of the present invention. 2 and 3 are a side view and a front view, respectively, showing a state of the spectacles of Fig. 1; 4 and 5 are a vertical sectional view and a bottom perspective view showing the state of the spectacles of Fig. 1, respectively.

The glasses according to the present embodiment are integrally formed as shown in Figs. However, the present invention is not limited thereto and various kinds of glasses known in the art may be used. For example, the present invention can be implemented in various forms such as a folding type, a clip type, a goggle type, and the like, as long as the configuration, position, and relationship between the constituent parts of the pair of reflectors, which are the main features of the present invention to be described later.

In this case, the term &quot; folding type &quot; means glasses in which a pair of legs are folded inward as in commonly used glasses, and clip type glasses means a fastening member for attaching to glasses, And a goggle type means a type that can be worn by wearing a band or the like for wearing on the head of a user or by covering the glasses on the glasses. As described above, the glasses capable of securing the two-directional view according to the present invention are not limited to the wear mode or the leg or band for fixing the head, and can be variously implemented.

The glasses 10 according to the present embodiment include a frame 100 that forms the outer shape of the glasses. The frame 100 includes a spectacle leg 110, a first support portion 130, an extension portion 120, and a second support portion 140.

The pair of eyeglasses legs 110 are provided in a pair and are each formed into a bent shape so as to be fixed to an ear of a human body. The first support part 130 is formed in a shape that connects the front sides of the pair of eyeglasses legs 110 and is formed in a plate shape located on a plane parallel to the eyeglass legs 110.

The extension portions 120 are formed to extend downward from both sides of the first support portion 130. The second supporting portion 140 is formed in the shape of a plate connecting the lower ends of the pair of extending portions 120.

3, the first supporting portion 130, the extending portion 120, the second supporting portion 140, and the other extending portion 120 are formed as a through- (S1).

The wearer wearing the glasses 10 according to the present embodiment can ensure the field of view through the through-hole S1 for securing the view.

As another embodiment, it is possible that a lens for objective correction such as vision correction or ultraviolet ray blocking may be provided in the penetration portion S1 for securing the visual field such as a conventional goggles.

Referring to FIGS. 4 and 5, the frame 100 includes a first reflector 230 and a second reflector 240.

The first reflecting part 230 is attached to the lower part of the first supporting part 130 and the second reflecting part 240 is attached to the upper part of the second supporting part 140. A general mirror may be used for the first reflector 230 and the second reflector 240, but in the present embodiment, it is preferable to use a front reflector. This will be described in detail later.

The first reflecting part 230 is provided on the upper part of the frame, that is, the lower part of the first supporting part 130, and reflects the light incident from the lower side toward the second reflecting part 240 side. The second reflecting portion 240 is provided on the upper portion of the second supporting portion 140 and reflects the light reflected from the first reflecting portion 230 toward the wearer's eye.

At this time, the first reflector 230 and the second reflector 240 are provided at the upper and lower portions of the frame 100, respectively, so that the first reflector 230 and the second reflector 240 are spaced apart from each other by a predetermined distance, .

Meanwhile, the first reflector 230 and the second reflector 240 may be one continuous reflector, but they may be separated into two or more portions. For example, the second reflecting part 240 may be provided as a pair corresponding to the left and right eyes of the user, and the first reflecting part 230 may also be provided as a pair.

6 to 8, the positions and the angles of the first and second mirrors of the spectacles according to the embodiment and the operation principle thereof will be described. FIG. 6 is a schematic view showing the principle of operation of the spectacles according to the embodiment of the present invention, and FIGS. 7 and 8 are enlarged views of the eyes around the eyes.

As described above, the first reflector 230 and the second reflector 240 are provided on the upper and lower portions of the frame 100, respectively, so that the visibility of the wearer can be ensured in the front D1, The view of the lower side D2 can be ensured through the refraction of the reflecting portion 230 and the second reflecting portion 240. [ That is, it functions to divide the view of the person so that the smart device 300 of the front D1 and the bottom D2 can be viewed simultaneously.

Specifically, in the case of the eyeglasses according to the present embodiment, the horizontal distance from the first reflecting portion 230 to the user's eye EYE is equal to the horizontal distance from the second reflecting portion 240 to the user's eye EYE It is preferable that it is formed largely. This means that the first reflector 230 is formed at a position distant from the eye on the basis of the horizontal distance so that the viewer can look at the lower object without interference from the human body or the second reflector 240. The position of the first reflector 230 may be closer to the human body than the position of the second reflector 240 but the position of the first reflector 230 and the second reflector 240 There arises a problem that a position and an angle are severely restricted and the second reflecting part partially covers the field of view ahead.

The distance from the user's eye EYE to the center of the second reflector 240 on the schematic longitudinal section as shown in FIGS. 6 and 7 is K1, the distance from the center of the second reflector 240 to the first reflector 230 The vertical length L1 of the second reflector 240 is L2 and the vertical length L2 of the first reflector 230 is L2, the vertical length L1 of the second reflector is expressed by the following expression 1 is satisfied.

[Formula 1]: L1 < = L2 x K1 / (K1 + K2)

When the longitudinal length of the second reflecting portion 240 satisfies the condition of Equation 1, when the wearer watches the lower object through the second reflecting portion 240, the longitudinal boundary of the first reflecting portion 230, 1 phase in the longitudinal direction of the half-width section 230 can be prevented from being observed.

Likewise, when the wearer touches the lower surface of the second reflector 240 through the second reflector 240 by forming the first reflector 230 in the lateral direction longer than the second reflector 240 in the lateral direction, It is preferable that the horizontal boundary of the first reflector 230 and the image of the outer side in the horizontal direction of the first reflector 230 are not observed.

Referring to FIG. 8, the second reflector 240 can form a viewing angle within a predetermined angle range (? 1 to? 2) from the user's eye (EYE) with respect to the front, that is, . Specifically, it is preferable that the second reflecting portion 240 is provided in a view angle of 21 degrees down to 37 degrees. When the second reflecting portion 240 is positioned at a viewing angle of less than 21 degrees downward, the second reflecting portion 240 is more easily observed but the view of the front D1 is partially covered, thereby causing a problem of narrowing the front view When the part of the second reflector 240 is located up to an angle larger than 37 degrees downward, the user has to look down too much, which makes it difficult to ensure a comfortable view.

In addition to the condition that the second reflector should be positioned within the viewing angle as described above, an inclination must be formed in order to reflect the light transmitted from the first reflector 230 to the eye EYE of the user and to transmit the reflected light. Specifically, the downward inclination of the second reflector 240 is formed on the user's eye EYE side, and the inclination degree? 3 is preferably 15 to 25 degrees with respect to the horizontal plane. If the inclination angle? 3 is less than 15 degrees, the first reflector 230 must be located far away from the eye EYE. If the inclination angle? 3 is greater than 25 degrees The position of the first reflector 230 must be excessively moved toward the user's eye EYE and the inclination of the first reflector 230 must be increased to secure the view of the lower side.

The incident angle? 4 of the light incident from the center of the first reflector 230 to the center of the second reflector 240 is preferably greater than 15 degrees. When the incident angle 4 is smaller than 15 degrees, a part of the second reflector 240 may interfere with the image reflected to the user's eye EYE through the first reflector 230. [ On the other hand, when the incident angle? 4 is excessively large, the position of the first reflecting portion 230 is excessively distanced from the eye EYE of the user. At this time, the first reflection part 230 is formed to have an inclination of -5 degrees to 5 degrees with respect to the horizontal plane, so that the above-mentioned incident angle? 4 can be adjusted and adjusted. If the inclination angle of the first reflector 230 with respect to the horizontal plane is too large or small, it is difficult to secure downward field of view or an image transmitted through the first reflector 230 may be interfered with by the second reflector 240 .

On the other hand, the downward viewing angle [theta] 5 secured through the second reflector 240 and the first reflector 230 from the eye EYE of the user has a viewing angle of 15 to 20 degrees on the schematic vertical cross- .

When the viewing angle is set to about 15 to 20 degrees, it is possible to sufficiently secure a viewing angle required for controlling a smart phone, a tablet or the like near the user's knee.

9 and 10, the configuration and characteristics of the spectacles according to the embodiment will be described. FIG. 9 is a schematic view showing the principle of operation of a rear reflector, and FIG. 10 is a schematic view showing the operation principle of a front reflector according to an embodiment of the present invention.

As described above, it is preferable that the first reflection part and the second reflection part are formed as front reflection mirrors.

9, the light incident on the first reflecting portion 230a is reflected by the first reflecting portion 230a in addition to the reflecting surface 231a on the rear surface of the first reflecting portion 230a, Reflection occurs on the surface of the substrate. Likewise, the light incident on the second reflective portion 240a is reflected at the surface of the second reflective portion 240a and at the reflective surface 241a.

Accordingly, even when the light W1 corresponding to one phase is incident, the ghost image W12 is generated in the first reflection portion 230a in addition to the main refraction path W11. A large number of ghost images W112, W121 and W122 are generated in addition to the main image W111 due to the same phenomenon occurring in the second reflecting portion 240a.

These ghost images cause the quality of the image of the object to be significantly degraded and cause the wearer's dizziness.

For this reason, as shown in FIG. 10, it is preferable to use a front reflection method having reflection surfaces 231 and 241 on the front surfaces of the first reflection portion 230 and the second reflection portion 240, respectively.

That is, when the first reflector 230 and the second reflector 240 of the front reflector according to an embodiment of the present invention are used, only a main image according to a single path is generated without generating a ghost image So that the effect of improving the quality of the image compared to the prior art can be obtained.

Referring to Fig. 11, the glasses and the operation method thereof according to another embodiment will be described. 11 is a schematic view showing a spectacle according to another embodiment.

11, the eyeglasses according to the present embodiment have a horizontal distance from the first reflecting portion 230b to the user's eye EYE to a horizontal distance from the second reflecting portion 240b to the user's eye EYE, As compared with the above-described embodiment.

That is, the first reflector 230b is closer to the user's eye EYE than the second reflector 240b on the horizontal distance, and the image of the lower smartphone is disposed on the second reflector 240b And is incident on the first reflecting portion 230b through a space between the user's eyes EYE.

In addition, the functions through these configurations are the same as the embodiments described above. In other words, it is possible to view the forward view through the first reflector 230b and the second reflector 240b, and at the same time, to move the eyes of the user, can do.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. have.
