Description

Technical Field

[0001] The invention relates to a pair of glasses with nose pads capable of adjusting angles in various directions. Background Art

[0002] Glasses range from standard glasses made of transparent materials with a modulated refractive index to sunglasses and goggles that reduce transmittance to protect the user's eyes from glare or UV rays. Commonly used sunglasses are made by adding colorants or coating or depositing light-reflecting materials onto transparent materials to prevent glare or protect the eyes from UV rays.

[0003] On the other hand, glasses generally include transparent or partially tinted lenses, a frame to support the lenses, temples connected to the frame and mounted on the user's ears to fix the glasses on the user's face, and nose pads to support the glasses on the user's nose to fix them on the face.

[0004] Glasses wearers have faces of varying shapes and sizes, and when purchasing pre-made glasses, they often do not fit their face shape or are uncomfortable to wear. Furthermore, it is difficult to wear the glasses as desired.

[0005] Existing glasses are mass-produced and are generally made in a uniform shape with the same position and angle. Users of existing products do not wear glasses according to their own conditions, but adjust themselves according to the manufactured glasses.

[0006] Therefore, it is necessary to research new functions that can change the wearing position of glasses in various directions so that people with different face shapes and sizes can wear glasses optimally according to their faces.

[0014] Furthermore, the present invention provides glasses that can firmly maintain the angle of the nose pad after the angle of the nose pad is adjusted, thereby preventing the angle from changing again in a manner that is undesirable to the user.

[0015] In addition, a pair of glasses is provided which can be conveniently mass-produced.

[0016] The purpose of the present invention is not limited to the above-mentioned technical problems, and other technical problems not mentioned will become more apparent to those skilled in the art through the following description.

[0017] Problem Solutions

[0018] To solve the above-mentioned problem, a pair of glasses according to one embodiment of the present invention includes: a lens; a frame coupled to a portion of the edge of the lens; a nose pad frame formed by extending from the frame at the center bottom of the lens, or coupled to the lens; a coupling portion including a plurality of coupling axes extending from the nose pad frame and protruding toward the user's face, extending in the up-down direction and spaced apart from each other; an adjusting tip coupled to the coupling portion so as to be movable up-down along the coupling axis of the coupling portion and rotatable left-right along the coupling axis; and a nose pad pad coupled to the adjusting tip and movable as the adjusting tip moves in the up-down direction and rotates left-right.

[0019] In addition, one end of the adjustment tip is combined with the combining shaft, and the other end is combined with the nose pad; the other end of the adjustment tip also includes a pad fixing portion that protrudes in the up and down directions and is inserted into the inner space of the nose pad to fix the nose pad.

[0020] In addition, the multiple coupling axes of the coupling part protrude from both ends of the nose pad frame along the user's face and are inclined from the upper part to the lower part. The coupling axes facing each other are symmetrical with respect to a virtual line passing through the center of the lens in the upper and lower directions and the distance becomes farther from the upper part to the lower part.

[0021] In addition, the coupling portion includes a connecting portion that separates and connects the coupling axis and the nose pad frame and has a thickness less than that of the coupling axis; the adjustment tip includes a clamping portion formed into a hollow space with a shape corresponding to the coupling axis to be clamped and coupled with the coupling axis.

[0022] Furthermore, the width of the opening of the clamping portion of the adjusting tip, into which the coupling shaft is inserted, is greater than the thickness of the connecting portion.

[0023] In addition, the adjustment tip also includes a stopper having a plurality of recessed areas repeatedly formed on a surface opposite to the coupling shaft coupled to the clamping portion; the coupling portion also includes an angle adjustment portion protruding from the coupling shaft and inserted into any one of the stoppers.

[0024] Furthermore, the angle adjustment portion and the stopper portion are provided on an inner side of the clamping portion and face each other at a position where the adjustment tip and the coupling shaft are in coupling contact with each other.

[0026] In addition, the adjustment tip also includes a rotation stop step formed at both ends of the clamping portion to stop rotation when one end of the adjustment tip contacts the nose pad frame; the thickness of the rotation stop step becomes thicker as it approaches the position opposite to the coupling portion.

[0027] Furthermore, in the rotation stopping step, an area where one end of the adjusting tip contacts the nose pad frame is larger than an area formed by a cross section of an upper end adjacent thereto.

[0028] Furthermore, a vertical length of the regulating tip in contact with the coupling shaft is smaller than a vertical length of the coupling shaft.

[0029] Furthermore, the adjustment tip is movable in an up-down direction along the coupling axis.

[0030] In addition, the adjustment tip further includes a plurality of adjustment steps that are spaced apart and recessed from each other; the coupling portion further includes a stop terminal that protrudes to be inserted into one of the adjustment steps; and the position of the adjustment tip in the up and down directions is adjusted by the stop terminal.

[0031] In addition, the stop terminal is complementarily coupled with and fixed to a first adjustment step among the multiple adjustment steps; moves to a second adjustment step spaced apart from the upper end of the first adjustment step and is fixed, so that the adjustment tip moves to the lower end and is fixed; moves to a third adjustment step spaced apart from the lower end of the first adjustment step and is fixed, so that the adjustment tip moves to the upper end and is fixed.

[0032] In addition, the adjustment tip also includes a pad portion that is coupled to the inner surface of the adjustment tip constituting the clamping portion and is arranged between the inner surface of the clamping portion and the surface of the coupling shaft; when the adjustment tip rotates, the pad portion contacts and moves with the surface of the coupling shaft.

[0038] In addition, even if you wear prescription lenses, you can easily adjust the nose pad angle for convenient use.

[0039] In addition, after the angle of the nose pad is adjusted, the angle of the nose pad is firmly maintained to prevent the angle from changing again in a way that the user does not want.

[0040] Furthermore, the glasses can be easily mass-produced.

[0074] The advantages, features, and methods of the present invention will become apparent in conjunction with the accompanying drawings and the embodiments described in detail. However, the present invention is not limited to the embodiments described below and may be implemented in various forms. The purpose of these embodiments is to better illustrate the present invention and facilitate understanding by those skilled in the art. The present invention is limited only by the claims. Throughout this specification, like reference numerals refer to like elements. In the drawings, the sizes and relative sizes of layers and regions may be exaggerated for ease of illustration.

[0075] Terms such as “below,” “beneath,” “lower,” “above,” and “upper” that indicate relative positions in space are used to describe the relationship between one element or component and other elements and components.

[0076] For ease of description, terms such as "first" and "second" are used to refer to various elements, but these elements are not limited by these terms. These terms are intended solely to distinguish one component from another. Therefore, within the scope of the present invention, the first element described below may also be the second element.

[0077] The glasses of the present invention can be applied to eyeglasses having nose pads for supporting the glasses on the upper end of the nose of the user, sunglasses, sports goggles, goggles for various purposes, and the like.

[0078] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0079] Figure 1 is an oblique view of the glasses according to one embodiment of the present invention as viewed from the direction of the user wearing them, Figure 2 is an oblique view of glasses according to an embodiment of the present invention viewed from the outside toward the user, Figure 3 FIG. 1 is an oblique view of the glasses according to an embodiment of the present invention viewed from another direction.

[0080] Furthermore, in order to illustrate the glasses of the present invention in more detail, Figure 4 is a front view of glasses according to an embodiment of the present invention, Figure 5 is a rear view of glasses according to an embodiment of the present invention, Figure 6 is a plan view of glasses according to an embodiment of the present invention, Figure 7 FIG. 4 is a bottom view of glasses according to an embodiment of the present invention.

[0081] See Figures 1 to 7 , a pair of glasses according to an embodiment of the present invention includes: a lens 100; a frame 200, which is combined with a portion of the edge of the lens 100; a nose pad frame 300, which is extended from the frame 200 at the center bottom of the lens 100, or is combined with the lens 100; a coupling portion 400, including a plurality of coupling axes 410 extending from the nose pad frame 300 and protruding toward the user's face, extending in the up-down direction and spaced apart from each other; an adjusting tip 700, which is combined with the coupling portion 400 so as to be movable up-down along the coupling axis 410 of the coupling portion 400 and to rotate left-right with the coupling axis 410 as an axis; and a nose pad 500, which is combined with the adjusting tip 700 and can move along with the up-down movement and left-right rotation of the adjusting tip 700.

[0082] When the glasses are worn, the lens 100 can be arranged at a position corresponding to the user's eyeballs and can be made of a transparent material so that the user can see external objects. Without limitation, the lens 100 can be formed to protect the user's eyes from strong light, for example, by including a colorant or attaching a colored film. In addition, various other additional configurations can also be adopted, such as ultraviolet absorbers, anti-fog treatment (Anti-Fog), etc. The lens 100 can be made of glass, or it can be made of a resin material such as polycarbonate (PC), or it can be made of various materials commonly used in the art. In addition, it can be in the form of a combination of lenses corresponding to the left eye and the right eye respectively and a frame, or it can be an integrally molded lens as shown in the figure, but it is not limited. When the lens 100 is integrally molded as shown in the figure, the part where the user's nose bridge is located can have a structure that is concave from bottom to top.

[0083] The frame 200 can be coupled to a portion of the edge of the lens 100 to secure the lens 100. The glasses are then secured to the wearer's face via the temples 600 connected to the frame 200. As shown in the figure, the frame 200 can be coupled to only a portion of the ends of the lens 100 to reduce the size of the frame, or it can be coupled to the entire edge of the lens. Furthermore, the frame 200 can be coupled to various configurations not shown. Specifically, the lens and frame of the present invention can be coupled using various methods commonly used in the art.

[0084] The temples 600 are connected to the frame 200 via connecting components and are typically connected to both ends of the lens 100 so that the temples 600 can be attached to the user's ears, thereby securing the glasses to the user's face. The temples 600 can be made of various materials, such as plastic resin or metal, and can be stretched along the user's face to secure them to the user's ears. Furthermore, the temples 600 can be provided with anti-slip components made of rubber or silicone to prevent the glasses from slipping off the user. Furthermore, the temples 600 can be designed to fold around the connecting components so that when the user is not wearing the glasses, the temples 600 can be folded for minimal storage.

[0085] The nose pad frame 300 can be formed by extending from the frame 200 at the center bottom of the lens 100, or can be integrated with the lens 100. Specifically, the nose pad frame 300 is integrated with the lens 100 at the center bottom, but can also be a part of the frame 200 integrated at the edge of the lens 100. Furthermore, as shown in the figure, the nose pad frame 200 can be formed separately from the frame 200. In this case, when separated from the frame 200, the center bottom portion of the lens located at the wearer's nose bridge is integrated with a portion of the edge of the lens 100. Furthermore, both the nose pad frame 300 and the frame 200 can be made of various materials well known in the art, such as synthetic resins, polymer resins, metals, and the like.

[0086] The coupling portion 400 includes a plurality of coupling axes 410 extending from the nose pad frame 300 and protruding toward the user's face, extending in the vertical direction and spaced apart from one another. Specifically, the coupling portion 400 may be a star-shaped structure extending from the nose pad frame 300 itself and may be formed from the same material as the nose pad frame 300. The coupling portion 400 is the portion to which the adjustment tip 700 of the nose pad 500 is coupled. The adjustment tip 700 can be coupled to the coupling portion 400 to couple the nose pad 500 to the nose pad frame 300 of the glasses.

[0087] The adjustment tip 700 is coupled to the coupling portion 400 and can move up and down along the coupling axis 410 of the coupling portion 400 and rotate left and right about the coupling axis 410. When the adjustment tip 700 is coupled to the nose pad 500 via the coupling axis 410, the nose pad 500 can be moved up and down relative to the nose pad frame 300 (or coupling portion 400), or a portion of the nose pad 500 can be moved left and right. In other words, the adjustment tip 700 functions as a connecting member connecting the coupling portion 400 extending from the nose pad frame 300 and the nose pad 500. The nose pad 500 can be adjusted left and right while coupled to the coupling portion 400 via the adjustment tip 700. Therefore, people with relatively narrow noses can use the nose pad 500 at a narrow angle by narrowing the ends of the nose pad 500, while people with relatively wide noses can use the nose pad 500 at a wide angle by opening the ends of the nose pad 500.

[0088] The nose pad 500 can be formed of various elastic or flexible materials, such as rubber or EPDM (ethylenepropylene diene monomer). The nose pad 500 allows the glasses to be placed on the user's nose bridge so that the lenses 100 are facing the user's eyes. As shown in the figure, the nose pad 500 can be in a form in which the two ends that are in contact with the upper end of the nose are connected to each other in the middle part, and extend downwardly with the middle as the center and are separated by a certain distance. That is, the connecting part at the upper end is in a quasi-bent shape ("^" shape), and the bent part can be in various shapes, such as a straight line or curve. However, it is not limited to this, and it can be different from the figure, and can be in a form in which multiple nose pads are arranged at both ends of the nose bridge and are formed separately, and each nose pad is combined with each adjustment tip.

[0089] Furthermore, the nose pad 500 can be detachable and come in various sizes and shapes, allowing the user to select and use a variety of shapes and sizes according to their preferences. For example, when a pair of glasses is provided, relatively large and small nose pads 500 are provided. The user can then select the appropriate size of nose pad 500 based on their face shape, size, or preferences. If the user wishes to use a larger nose pad, the larger nose pad can be attached to the adjustment tip 700. If the user wishes to switch to a smaller nose pad, the larger nose pad can be removed and the smaller nose pad can be attached to the adjustment tip 700.

[0090] On the other hand, people who wear glasses have unique facial shapes, depending on their individual circumstances and ethnicity. Face shapes and sizes vary greatly, and purchasing pre-made glasses often results in them not fitting their face shape or being uncomfortable. Furthermore, it can be difficult to wear glasses the way you want them. People's noses vary in shape, from high to low, round to convex, pointed to flat. Despite this, existing glasses often feature nose pads with a uniform shape and position and angle. People who buy pre-made glasses either force themselves to wear them even if they don't fit their face shape, or simply try them on and choose the one that suits their face shape.

[0091] Furthermore, mass-produced eyewear suffers from reduced production efficiency due to the production of different product groups tailored to specific customer needs. Specifically, separate products tailored to the average Western face shape and those tailored to the average Asian face shape reduce manufacturers' production efficiency. This is particularly problematic for those who wear their own prescription glasses in addition to sunglasses and goggles, making it even more difficult to find the right pair of glasses.

[0092] Therefore, the eyeglasses of the present invention can adjust the angles of the two ends of the nose pad 500 according to the shape of the user's nose bridge by adjusting the joint 400 and the adjustment tip 700. Furthermore, because the nose pad 500 can be adjusted vertically, the user can easily adjust the eyeglasses to their facial shape and adjust the lens position to suit their needs. Specifically, while the angles of the two ends of the nose pad 500 supported on the nose bridge can be adjusted left and right, the position of the nose pad itself can be moved vertically, allowing the user to easily adjust the nose pad 500 in all directions.

[0093] In other words, the nose pad 500 can be coupled to the adjustment tip 700 to move up and down as the adjustment tip 700 moves up and down, thereby adjusting the position of the lens 100 to the wearer's preference. Specifically, lowering the adjustment tip 700 raises the lens 100, while raising it lowers it. Furthermore, by rotating the adjustment tips 700, located at either end of the user's nose bridge, left and right, the width between the nose pads 500 can be adjusted to suit the shape of the wearer's nose bridge. By rotating the adjustment tips 700 left and right, the distance (width) between the nose pads 500 can be widened, making it easier for people with wide or thick noses to wear glasses. Conversely, by rotating the adjustment tips 700 left and right, the distance (width) between the nose pads 500 can be narrowed, making it easier for people with narrow or tall noses to wear glasses. It will be appreciated that the position and angle of the nose pad 500 can be adjusted by generating relative movement between the adjustment tip 600 and the coupling portion 400, driven by force transmitted through the nose pad 500.

[0094] also, Figure 8is an exploded perspective view schematically showing glasses according to an embodiment of the present invention, Figure 9 This is an exploded perspective view schematically showing a nose pad frame portion according to an embodiment of the present invention. Figure 10 This is an exploded oblique view of the nose pad frame according to one embodiment of the present invention as viewed from another direction. Figure 11 is an oblique view of an adjustment tip according to an embodiment of the present invention viewed from one direction, Figure 12 is an oblique view of the adjustment tip according to an embodiment of the present invention viewed from another direction, Figure 13 FIG. 1 is an oblique view of the adjustment tip according to an embodiment of the present invention viewed from another direction. Figure 14 is an oblique view of a nose pad frame according to an embodiment of the present invention viewed from another direction, Figure 15 FIG. 1 is an oblique view of a nose pad according to an embodiment of the present invention viewed from another direction.

[0095] See Figures 8 to 15 , the nose support frame 300 may include a lens joining line 320 formed with a recessed area corresponding to the shape of the lens 100 so that the lens 100 is combined with the upper end. In addition, the nose support frame 300 may also include a power lens fixing portion 310 for inserting and fixing a separate power glasses (not shown). The power lens fixing portion 310 may include a groove and a fixing portion to easily combine and separate the power lenses. The nose support frame 300 has a shape that is inclined downward along both sides with the center upper end as the basis (for example, a ∧ shape or a ∩ shape) so that it can be easily installed on the user's nose bridge. That is, it has a shape that is inclined downward in the left and right directions from the center upper end, and the distance becomes farther as it goes down. In other words, the shape of the nose support frame 300 can be a structure installed on the upper end of the nose bridge in the glasses.

[0096] Furthermore, the multiple coupling axes 410 of the coupling portion 400 protrude from both ends of the nose pad frame 300 toward the user's face and are formed to be inclined from top to bottom. The facing coupling axes 410 are symmetrical about an imaginary line passing vertically through the center of the lens 100, and their distance from top to bottom increases. Like the nose pad frame 300, the coupling axes 410 can also have a symmetrical structure that is inclined diagonally from top to bottom. This allows the nose pad 500 coupled to the coupling axes 410 to be supported by both sides of the upper end of the user's nose bridge when the user wears the glasses.

[0097] Furthermore, the coupling shafts 410 of the coupling portion 400 may be formed in a plurality of spaced-apart configurations, extending from the nose pad frame 300 and protruding toward the user's face, extending vertically. The coupling portion 400 may be formed as an extension from the nose pad frame 300 or integrally formed. The coupling shaft 410 may protrude upward from the surface of the nose pad frame 300 to form an axis for coupling with the adjustment tip 700, but may be relatively long vertically. Furthermore, the coupling shaft 410 may be formed to have a circular cross-sectional shape or include a curve to allow the adjustment tip 700 to rotate at a certain angle. Specifically, one end of the adjustment tip 700 may be open to facilitate coupling and rotation with the coupling shaft 410. With respect to the outermost opening, the space becomes wider toward the inner side, allowing the adjustment tip 700 to be coupled and rotated while holding the coupling shaft 410. The adjustment tip 700 may be made of a material having a certain degree of elasticity, such as a synthetic resin, to facilitate coupling with the coupling shaft 410.

[0098] On the other hand, the adjustment tip 700 is coupled to the coupling shaft 410 at one end and to the nose pad 500 at the other end. The other end of the adjustment tip 700 also includes a pad securing portion 710 that protrudes vertically and inserts into the inner space of the nose pad 500 to secure the nose pad 500. Specifically, the adjustment tip 700 includes a pad securing portion 710 that protrudes in a longer direction relative to the coupling shaft 410 and can be inserted into the inwardly recessed coupling groove 510 of the nose pad 500. The pad securing portion 710 of the adjustment tip 700 protrudes at both ends relative to the central length of the adjustment tip 700, resulting in a longer length. This allows for insertion into the inner coupling groove 510 of the nose pad 500 to prevent easy detachment. The inner coupling groove 510 of the nose pad 500 may have a shape corresponding to that of the adjustment tip 700 and the pad securing portion 710, and can be clamped and secured internally by the elastic or flexible material of the nose pad 500 to prevent easy detachment.

[0099] On the other hand, the coupling portion 400 may include a connecting portion 420 that separates and connects the coupling shaft 410 and the nose pad frame 300 and has a thickness smaller than that of the coupling shaft 410. The connecting portion 420 is used to ensure a space between the coupling shaft 410 coupled to the adjustment tip 700 and the nose pad frame 300 so that the adjustment tip 700 can rotate along the axis of the coupling shaft 410. It can be understood that the nose pad frame 300 and the coupling shaft 410 are connected at both ends based on the connecting portion 420.

[0100] Furthermore, the adjustment tip 700 may include a clamping portion 720 formed into a hollow space corresponding in shape to the coupling shaft 410 to securely engage the coupling shaft 410. The clamping portion 720 refers to a space divided into a hollow space, the cross-section of which has a shape corresponding to that of the coupling shaft 410 and may be open at one end, allowing the coupling shaft 410 to be inserted and engaged with the clamping portion 720. Furthermore, as described above, when the coupling shaft 410 is inserted through the open portion of the clamping portion 720, the inner space maintained by the coupling shaft 410 is wider, while the outermost open portion has a narrower area to prevent easy separation. That is, the portion of the coupling shaft 410 that is first inserted into the clamping portion 720 (the outermost open portion of the clamping portion 720) has a relatively narrow open area, allowing the coupling shaft 410 to be gripped and engaged with the clamping portion 720 to prevent easy separation. To this end, in a vertical cross-section, the outermost open width of the clamping portion 720 is preferably smaller than the width of the center portion of the coupling shaft 410.

[0101] Furthermore, the width of the opening of the clamping portion 720 of the adjustment tip 700, into which the coupling shaft 410 is inserted, is greater than the thickness of the connecting portion 420 of the coupling portion 400. This ensures a certain distance between the clamping portion 720 and the connecting portion 420, preventing unnecessary interference with the rotation of the adjustment tip 700. Specifically, when the adjustment tip 700 rotates about the coupling shaft 410 (to adjust the angle of the nose pad 500), the adjustment tip 700 and the connecting portion 420 of the coupling portion 400 are prevented from contacting each other and interfering with the rotation.

[0102] On the other hand, see Figure 13 and Figure 14 The vertical length P1 of the adjustment tip 700 in contact with the coupling shaft 410 is less than the vertical length P2 of the coupling shaft 410. In other words, the portion of the adjustment tip 700 that is coupled to the coupling shaft 410 can be less than the total vertical length of the coupling shaft 410. Therefore, the adjustment tip 700 can move vertically along the coupling shaft 410, thereby adjusting the position of the nose pad 500.

[0103] Figure 16 This is a perspective view showing the combined relationship between the nose pad frame and the adjustment tip according to one embodiment of the present invention. Figure 17 To express the basis Figure 16 Schematic diagram of the cross section along AA'.

[0104] read Figure 16 and Figure 17 , and again refer to the adjustment tip from various angles. Figures 11 to 13 and detailed representation of the joint Figure 14The adjustment tip 700 further includes a stopper 740 having a plurality of recessed areas repeatedly formed on a surface opposite the coupling shaft 410 coupled to the clamping portion 720. The coupling portion 400 further includes an angle adjustment portion 440 protruding from the coupling shaft 410 and inserted into any one of the stopper 740. The angle adjustment portion 440 can be formed to face any one of the plurality of stopper 740, so that the adjustment tip 700 stops and maintains its state after partial rotation.

[0105] For example, suppose Figure 16 This is a schematic diagram showing the connection between the adjustment tip and the connection part set on the right side based on the user. There is a symmetrical part on the left side, and the angle of the adjustment tip can be adjusted by the angle adjustment part and the stopper. In the part set on the right side, as shown in FIG. Figure 16 As shown, when multiple stoppers 740 are formed at two locations spaced a certain distance apart, the angle adjustment portion 440 can be positioned at the first stopper on the left side, allowing the adjustment tip 700 to have a narrower angle. Subsequently, when a force is applied to the adjustment tip 700 to move it to the second stopper 740 on the right side, the adjustment tip 700 can change position to achieve a wider angle and maintain this position. The adjustment tip 700 can have multiple stoppers 740. When the angle adjustment portion 440 is moved and secured to any of the multiple stoppers 740, the adjustment tip 700 can rotate and stop. This allows the angle of the adjustment tip 700, and thus the angle of the nose pad 500, to be adjusted.

[0106] Furthermore, at the point where the adjustment tip 700 and the coupling shaft 410 engage and contact each other, the angle adjustment portion 440 and the stopper 740 are located inside the clamping portion 720 and face each other. That is, when the adjustment tip 700 rotates about the coupling shaft 410, the angle adjustment portion 440 and the stopper 740 can be located only inside the clamping portion 720 of the adjustment tip 700, within the rotation radius. This makes it easier to adjust the rotation angle of the adjustment tip 700 (and ultimately the nose pad). If the opposing portion of the angle adjustment portion and the stopper were located outside the clamping portion of the adjustment tip, greater force might be required to rotate the nose pad, or the adjustment tip might fall off the coupling shaft 410 during rotation. Therefore, by placing the angle adjustment portion 440 and the stopper 740 only inside the clamping portion 720, within the rotation radius of the adjustment tip 700, they prevent the adjustment tip 700 from separating and detaching from the coupling shaft 410 during rotation.

[0107] On the other hand, contrary to the illustrated embodiment, the adjustment tip further includes a stopper protruding from a surface opposite the coupling shaft coupled to the clamping portion; the coupling portion further includes an angle adjustment portion having a plurality of repetitively recessed areas formed on the surface of the coupling shaft; the stopper is inserted into any of the angle adjustment portions, allowing it to move between the angle adjustment portions and adjust the angle of the adjustment tip. That is, unlike the embodiment shown in the accompanying drawings, the protruding and recessed portions of the adjustment tip's angle adjustment portion and the coupling portion's angle adjustment portion may be formed in reverse.

[0108] Furthermore, the adjustment tip 700 can move up and down along the coupling axis 410. By moving the adjustment tip 700 up and down along the coupling axis 410, the nose pad 500 can be moved up or down on the bridge of the user's nose. When the adjustment tip 700 and the nose pad 500 coupled thereto move upward, the nose pad 500 can move relatively closer to the lens 100, thereby lowering the lens 100 relative to the user. Conversely, when the adjustment tip 700 and the nose pad 500 coupled thereto move downward, the nose pad 500 can move relatively farther away from the lens 100, thereby raising the lens 100 relative to the user. Thus, by moving the adjustment tip 700 up and down along the coupling axis 410, the height of the lens 100 can be adjusted according to the user's specific needs.

[0109] On the other hand, in order to ensure that the adjustment tip 700 can reliably maintain its position after changing position while moving it up and down along the coupling shaft 410, the adjustment tip 700 may further include a plurality of adjustment steps 730, and the coupling portion 400 may further include a stopper terminal 430 located opposite the adjustment steps 730. Specifically, the adjustment tip 700 may further include a plurality of adjustment steps 730 recessed at intervals from one another, and the coupling portion 400 may further include a protruding stopper terminal 430 configured to be inserted into one of the adjustment steps 730. The vertical position of the adjustment tip 700 is adjusted by the stopper terminal 430.

[0110] See again Figure 10 、 Figure 11 and Figure 12 In the coupling portion 400, the stopper terminal 430 can be formed to protrude outward from the connecting portion 420, while the adjustment step 730 can be provided outside the clamping portion 720, thereby separating and repeatedly forming the recessed areas. Furthermore, when the coupling portion 400 is coupled to the adjustment tip 700, the adjustment step 730 and the stopper terminal 430 can be positioned opposite each other. The stopper terminal 430 can be complementary inserted into one of the plurality of adjustment steps 730 to fix the relative position of the adjustment tip 700 and the coupling portion 400.

[0111] More specifically, when the adjustment tip 700 moves relative to the coupling portion 400, the stopper terminal 430 can complementarily engage with and be fixed to a first adjustment step among the plurality of adjustment steps 730. Subsequently, when a downward force is applied to the adjustment tip 700 from the outside, the stopper terminal 430 can move to a second adjustment step located above the first adjustment step (i.e., the adjustment tip moves relatively downward), thereby moving the adjustment tip 700 downward and being fixed. Conversely, when an upward force is applied to the adjustment tip 700 from the outside, the stopper terminal 430 can move to a third adjustment step located below the first adjustment step (i.e., the adjustment tip moves relatively upward), thereby moving the adjustment tip 700 upward and being fixed.

[0112] As described above, the present invention allows the adjustment tip 700 to rotate about the coupling axis 410 of the coupling portion 400, thereby adjusting the angle formed by the nose pad 500 while also being movable and fixed in the vertical direction of the coupling portion, thereby stably adjusting the height of the lens 100. Therefore, by adjusting the position of the nose pad 500 in multiple directions, the position of the glasses can be adjusted to suit various face shapes or the user's various preferences and conditions, thereby allowing the user to wear the glasses conveniently.

[0113] The adjustment tip 700 also includes rotation stop steps 750 formed at both ends of the clamping portion 720 to stop rotation when one end of the adjustment tip 700 contacts the nose pad frame 300. The rotation stop steps 750 prevent further rotation of the adjustment tip 700 after it has rotated to a certain angle. The nose pad 500, coupled to the adjustment tip 700, is used to stably position the glasses on the wearer's nose bridge, maintaining a certain angle based on the shape of the wearer's nose bridge. The glasses of the present invention allow the adjustment tip 700 to rotate along the coupling axis 410 to adjust the angle of the nose pad 500.

[0114] If the adjustment tip 700 is rotated beyond a specific angle, thereby forming a very narrow or very wide angle between the opposing nose pads 500, the nose pads 500 may not be able to support the user's nose bridge. For example, if the angle between the nose pads 500 is very narrow, the nose pads 500 may float on the nose bridge instead of being resting on the user's nose bridge. On the contrary, if the angle between the nose pads 500 is very wide or fully extended to form a 180° angle, the nose pads 500 may not be able to support the nose bridge, thus losing their function. The rotation stop step 750 of the present invention is used to prevent the nose pads 500 from narrowing below a specific angle or widening above a specific angle as described above, and can be set on both sides in conjunction with the axis 410 to prevent the adjustment tip 700 from rotating above a specific angle.

[0115] To this end, the thickness of the rotation-stop step 750 increases as it approaches the position opposite the coupling portion 400. In other words, in the rotation-stop step 750, the area where one end of the adjustment tip 700 contacts the nose pad frame 300 is greater than the area formed by the cross-section of the adjacent upper end. That is, on the same horizontal line, the thickness of the rotation-stop step 750 increases as it approaches the coupling portion 400, thereby limiting the adjustment tip 700 to rotation within a specific rotation radius. The rotation-stop step 750 protrudes from the adjustment tip 700 to increase the area facing the coupling portion 400. This allows the rotation-stop step 750 to be supported against the coupling portion 400 when the adjustment tip 700 rotates relative to the coupling axis 410 beyond the specific rotation radius, preventing further rotation.

[0116] The direction from the clamping portion 720 of the adjustment tip 700 toward the pad fixing portion 710 is defined as the vertical direction, and the direction in which the rotation stop steps 750 face each other is defined as the horizontal direction. The ratio of the vertical direction to the horizontal direction is defined as the aspect ratio. In this case, the aspect ratio can be gradually increased so that the rotation stop step 750 approaches the joint 400, thereby forming a step, thereby adjusting the rotation radius of the adjustment tip 700.

[0117] also, Figure 18 According to another embodiment, Figure 16 Schematic diagram of the cross section along AA'.

[0118] See Figure 18 In another embodiment of the eyeglasses according to the present invention, the adjustment tip 700 further includes a pad 760 coupled to the inner surface of the adjustment tip 700 constituting the clamping portion 720 and disposed between the inner surface of the clamping portion 720 and the surface of the coupling shaft 410. The pad 760 moves in contact with the surface of the coupling shaft 410 as the adjustment tip 700 rotates. The pad 760 prevents foreign matter from accumulating between the adjustment tip 760 and the coupling shaft 410 as the adjustment tip 700 rotates. The pad 760 can be formed of an elastic material such as rubber, or a soft silicone material. Furthermore, the pad 760 becomes thinner toward the outside and thicker toward the inside of the clamping portion 720 to prevent the coupling shaft 410 from peeling off when it is coupled to the clamping portion 720. At least a portion of the pad portion 760 may contact the surface of the coupling shaft 710 inside the clamping portion 720 to naturally remove foreign matter accumulated on the surface of the coupling shaft 710 when the adjustment tip 700 rotates.
