Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a spectacle frame with a windshield and a method for manufacturing the same. Specifically, when riding on a motorcycle or performing sports such as skiing, the glasses frame with a windshield integrally provided with a windshield capable of reducing the airflow entering the inside of the glasses or preventing the intrusion of the airflow and its It relates to a manufacturing method.
[0002]
[Prior art]
Sunglasses are often worn when riding a motorcycle or an open car, or performing outdoor sports such as skiing. By wearing sunglasses, not only can the eyes be protected from ultraviolet rays, but also the wind generated by high-speed movement can be prevented from directly hitting the eyes.
[0003]
In addition, goggles are provided in which a peripheral wall that prevents intrusion of wind and dust is provided at the entire peripheral edge of the frame or lens. Since the goggles can completely block the gap between the edge of the lens and the face around the eyes, the wind does not enter the inside of the lens or the frame, and the airflow does not act on the eyes.
[0004]
[Problems to be solved by the invention]
The lacrimal glands that supply tears to the eyes are located at the upper outer sides in the width direction of the left and right eyeballs, that is, above the corners of the eyes. Therefore, tears flow from the upper part of the corner of the eye toward the eyes, keep the eyes moist, and protect the eyes from various stimuli.
[0005]
On the other hand, when the face moves at a high speed in the direction of travel, the air current collides with the face, and the air current branches left and right at the nose line, and an air flow is generated sideways along the face. The airflow along the face flows into the gap between the glasses and the face even when wearing glasses. Moreover, the airflow acts on the surface of the eyeball in the direction opposite to the direction in which the tear flows. For this reason, even when wearing glasses, the tear flow is disturbed and the eyes dry out, often causing inflammation. Therefore, when running on a motorcycle or skiing, conventional sunglasses and glasses often do not function as wind evasion. In order to alleviate the above problem, spectacles configured to bring the lens and frame of the spectacles as close to the face as possible are provided.
[0006]
However, the airflow flowing along the face cannot be prevented from entering the inside of the glasses only by bringing the lens and the frame close to the face. In addition, if the lens is too close to the face, the user's eyelashes often hit the inner surface of the lens and often stain or damage the lens surface.
[0007]
On the other hand, since the goggles include a peripheral wall that surrounds the entire circumference of the eyes, airflow along the face can be completely prevented from entering the inner space of the glasses. However, since the peripheral wall is provided, the appearance of the user's face changes greatly. For this reason, there is resistance to always wear like glasses. Moreover, since it has to be worn while being pressed against the face using a rubber band or the like, it is troublesome to attach and detach. In addition, the inner surface of the lens of the goggles is easily cloudy because it is blocked from the outside air.
[0008]
Further, when a peripheral wall such as goggles is fixedly provided on the spectacle frame, the lens or rim portion protrudes from the face, and it is difficult to provide a good-looking appearance design.
[0009]
The present invention has been conceived in order to solve the above-mentioned problem, and it is possible to prevent the flow of tears from being disturbed by preventing the airflow along the face from acting from the eyes to the corners of the eyes. It is an object of the present invention to provide an eyeglass frame with a windshield that is easy to attach and detach, and that is excellent in design, and a method for manufacturing the same.
[0010]
[Means for Solving the Problems]
In order to solve the above problems, the present invention takes the following technical means.
[0011]
According to the first aspect of the present invention, the gap between the face and the lens edge or / and the face in the region from the inner edge in the width direction of the frame body holding the left and right lenses to the middle in the width direction of the upper and lower edges. And a windshield spectacle frame integrally provided with left and right windshield portions that reduce or block the gap between the frame body edge and the windshield portion using the material different in color from the frame body. The present invention relates to a structure in which a boundary groove extending along the boundary portion is formed on the outer surface of the boundary portion between the frame main body and the windshield portion while being integrally formed with the frame main body .
[0012]
In the present invention, an unprecedented windshield is integrally provided in a spectacle frame. The frame body in the present invention is not only a frame body having a rim portion arranged so as to surround the lens, but also a frame body configured to hold the left and right lenses so as to be suspended along the eyebrows. Applicable. Moreover, if the frame main body and the windshield portion can be integrally joined, the material and form of the members constituting them are not particularly limited.
[0013]
The windshield portion according to the present invention is a gap between the face and the lens edge or / and the face in a portion from the inner edge in the width direction of the frame body holding the left and right lenses to the middle portion in the width direction of the upper and lower edges. And a gap between the frame main body edge and the frame main body. In other words, the windshield portion is integrally extended from the inner surface of the frame body so as to surround the upper and lower edges of the eye and the eyes. In the eyeglass frame that holds the left and right lenses so as to hang along the eyebrows, a windshield portion extending from the frame body along the edge of the left and right lenses can be formed.
[0014]
The left and right windshield portions are preferably provided so as to surround a portion from the inner side in the width direction of the eye head to the upper and lower edge portions corresponding to the position in the width direction of the outer corner of the eye. By providing the upper and lower windshield portions up to the portion corresponding to the corner of the eye corner, the airflow acting on the eyes can be completely blocked. On the other hand, it is not necessary to block the outer side of the outer corner in the width direction. Depending on the purpose of use, the strength of the airflow acting on the face, etc., a sufficient effect can be exhibited even by a windshield that does not reach the corner of the eye.
[0015]
Further, it is only necessary to prevent the airflow from entering between the inner surface of the lens and the face, and the left and right windshield portions can be provided independently or continuously. When the left and right windshield portions are provided continuously, it is desirable to partition the left and right windshield portions in order to prevent airflow flowing in the width direction of the face.
[0016]
By providing the windshield portion, the flow path is changed so that the airflow flowing through the face extends along the outside of the windshield portion, and it is possible to prevent the airflow from flowing between the inner surface of the glasses and the face. In particular, it is possible to effectively prevent the airflow flowing along the face from acting from the head of the eye toward the corner of the eye. For this reason, the flow of tears is not disturbed, and it is possible to effectively prevent the eyes from drying up due to the airflow and causing inflammation, or the entry of foreign substances into the eyes. Further, even if there is a slight gap between the windshield portion and the face, it is possible to greatly relieve the effect of weakening the airflow and acting on the eyes.
[0017]
The windshield portion is formed inside the frame body in the normal form and at the center in the width direction, so that the appearance of the wearer's face or glasses is not greatly changed in the worn state. On the other hand, when the frame main body and the windshield portion are integrally formed of the same material, the frame main body and the windshield portion cannot be distinguished from each other, and the appearance of the glasses having a frame that is much thicker than a normal frame is obtained. In addition, since light does not enter through the gap between the inner surface of the glasses and the face, the surroundings of the eyes are darkened, and there is a possibility of giving a strange feeling to the person facing. Furthermore, it cannot be said that it is excellent in a desan-in manner.
[0018]
In the present invention, in order to avoid the inconvenience, the windshield portion is formed using a material having a color different from that of the frame body. By making the color of the windshield different from the color of the frame main body, it is possible to make the viewer distinguish the frame main body from the windshield, and alleviate or eliminate the above-mentioned uncomfortable feeling. Further, by recognizing the form of the windshield part, it is possible to give the spectacle frame an unprecedented appearance design. Further, even if the windshield portion is integrally formed with the frame body, the design is not lowered, and various designs can be applied to the windshield portion.
[0019]
The method for integrally forming the windshield portion on the frame body is not particularly limited. For example, the frame main body and the windshield portion can be integrally cut out from a laminated plate material obtained by laminating and joining resin plates of different colors. In addition, after the frame body and the windshield portion are separately formed from materials having different colors, they may be joined together by using an adhesive or the like. Furthermore, it is possible to integrally mold the resin with different colors by injecting it into a molding die capable of integrally molding the windshield frame.
[0020]
As in the invention described in claim 2, while the frame body is formed from a colored resin material, the windshield portion can be formed from a transparent resin material. When the windshield portion is formed of a transparent resin, the windshield portion becomes inconspicuous and the degree of recognition of the windshield portion in the glasses decreases, so that the impression that the frame body is thickened can be alleviated. Moreover, since light enters the interior space of the glasses from the windshield portion, it is possible to obtain the same appearance and wearing feeling as a normal glasses frame.
[0021]
Furthermore, in this invention, the boundary groove | channel extended along the said boundary part is formed in the boundary part outer surface of the said frame main body and the said windshield part .
[0022]
By forming the boundary groove, the frame main body and the windshield portion can be reliably identified. For this reason, it is possible to further reduce the influence on the appearance of the windshield portion. In addition, by forming the windshield portion with a transparent resin and providing the groove, light is refracted at the boundary groove portion, and a kind of prism effect is given to constitute an unprecedented frame design. The boundary groove is desirably provided along at least the upper edge portion of the windshield portion. This is because the upper edge of the windshield is the most prominent part of the spectacle frame.
[0023]
The invention described in claim 3 of the present application is such that a nose pad portion is formed between the left and right windshield portions. The nose pad part can be formed integrally with the windshield part, or can be provided separately from the windshield part. It is desirable that the nose pad portion has a shape, a height, and the like so that the windshield portion contacts the face of the user. Further, when the height adjustable nose pad portion is provided, the windshield portion can be surely brought into contact with the user's face to obtain a high wind avoidance effect. As long as the function of the windshield is not inhibited, the form of the nose pad part is not particularly limited, and a conventional nose pad type nose pad part can also be provided.
[0024]
In the invention described in claim 4 of the present application, the laminated acetate resin plate integrally joined with the colored acetate resin plate and the transparent acetate resin plate is cut out to form the frame body from the colored acetate resin plate portion. The windshield portion is formed from the transparent acetate resin plate portion.
[0025]
Acetate resin, which is a cellulosic resin, is a resin material widely used for spectacle frames and can be easily molded and joined. On the other hand, the windshield portion according to the present invention has a thickness (extended height) equivalent to that of the rim portion, and is provided in a wide range along the inner surface of the glasses. For this reason, when it is formed by retrofitting, it is often limited by strength, design, and the like. Further, in the post-processing, it is necessary to devise for securing the adhesive strength and the like. In the present invention, in order to avoid the above disadvantages, the frame main body and the windshield portion are integrally formed from a resin plate in which a colored acetate resin constituting the frame main body and a transparent acetate resin constituting the windshield portion are laminated in advance. It is what was carved into.
[0026]
The invention described in claim 5 of the present application relates to glasses with windshield configured to include the frame body described in any one of claims 1 to 4 . Usually, spectacles are produced by fitting a lens into the rim of the frame body and connecting temples. In the glasses with windshield according to the present invention, the windshield portion is formed integrally with the frame body.
[0027]
In the invention described in claim 6 of the present application, the gap between the face and the lens edge or / and the face in the region from the inner edge in the width direction of the frame main body holding the left and right lenses to the intermediate portion in the width direction of the upper and lower edges. Is a method of manufacturing a glass frame with a windshield that integrally includes left and right windshield sections that reduce or block the gap between the frame and the frame body edge, and stacks and integrates multiple resin plates of different colors A resin laminate forming step, an intermediate forming step in which the laminate is heated and press-molded to form a frame intermediate, and a cutting or / and grinding process is performed on the intermediate so that the frame main body and the windshield are formed. a molding step shaving integrally formed with a different resin plate part section, the boundary outer surface of the frame body and the windshield portion, N including a boundary groove forming step of forming a boundary groove extending along said boundary Constructed.
[0028]
If the resin laminated body formation process can integrate the resin board from which a color differs, a various method is employable. They can be joined simply by thermal processing, or can be integrated using a solvent or an adhesive . The number of resin plates to be laminated is at least two. However, when a special design or the like is added or the thickness of the windshield portion is increased, three or more resin plates can be laminated.
[0029]
The intermediate body forming step is a step of giving a rough shape of the spectacle frame to the laminated body, and increases the efficiency of the subsequent cutting step. Moreover, since the rough curved surface form of spectacles can be provided, the thickness of a laminated body can be reduced and material used can also be reduced.
[0030]
The cut-out forming step is a step of forming a spectacle frame main body by cutting or / and grinding the intermediate body. Various mechanical devices can be used to perform the above-described cutting process. Further, the frame can be formed using not only a mechanical device using a cutting blade but also various processing devices such as a laser processing machine.
[0031]
By cutting out the frame main body from the laminated resin plates, it becomes possible to form a frame main body and a windshield portion that have different colors and are completely integrated. Moreover, even if the thickness (height) of the windshield portion is increased, it can be easily coped with only by changing the thickness of the laminated resin plates.
[0032]
Further, in the above Symbol boundary groove forming step, the boundary outer surface of the frame body and the windshield portion, forming the boundary groove extending along said boundary.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0041]
1 to 5 show an embodiment of glasses with windshield according to the present invention.
[0042]
As shown in these drawings, the windshield glasses 1 are configured by holding left and right lenses 6 and 6 on a frame body 2 made of acetate resin, like the conventional glasses of this type. The frame main body 2 includes left and right rim portions 3 and 3 that are held so as to surround the lenses 6 and 6, and a bridge portion 4 that connects the rim portions 3 and 3. A pair of temples 5 and 5 are rotatably connected to outer edge portions of the rim portions 3 and 3 via hinges 8 and 8.
[0043]
In the glasses 1 with the windshield according to the present embodiment, the rim portions 3 and 3 are extended toward the user's face in the region from the inner edge in the width direction to the middle portion in the width direction of the upper and lower edges. Left and right windshield portions 7 and 7 that can reduce or block the gap between the face and the rim portions 3 and 3 are provided. The windshield portions 7 and 7 are formed integrally with the rim portions 3 and 3, and an inner wall portion 7 c that extends from the inner edge portion in the width direction of the rim portion 3 so as to surround the eyes, and a rim An upper wall portion 7a extending from the upper edge portion of the portion 3 and a lower wall portion 7b extending from the lower edge portion of the rim portion 3, and these wall portions are continuous along the rim portion 3. It is formed and configured.
[0044]
As shown in FIGS. 3 and 4, the upper wall portion 7 a and the lower wall portion 7 b are formed in a tapered shape whose height decreases outward in the width direction, in the vicinity of the user's outer corner. It is set so as to contact the face F of the user up to the corresponding position in the width direction.
[0045]
Further, in the present embodiment, the concave nose pad portion 4 a that contacts the user's nose on the back surface of the bridge portion 4 and determines the distance between the face F and the lenses 6 and 6 is replaced with the windshield portion 7. And is formed integrally. Moreover, the height of the nose pad part 4a is set so that the windshield part 7 can come into contact with the face around the eyes of the user in the mounted state.
[0046]
The nose pad portion 4a is formed between the inner surface of the glasses and the face by the windshield portion 7 between the inner side in the width direction of the user's eyes and the upper and lower edges corresponding to the position in the width direction of the outer corner of the eye. Seal the gaps that will be made. As a result, the flow path of the airflow along the user's face that is generated due to high-speed movement or the like is changed, and the airflow flows between the glasses and the face and does not act on the eyes. As a result, it is possible to prevent tear flow from being obstructed and dry eyes or inflammation.
[0047]
On the other hand, as shown in FIGS. 1 and 2, the windshield portion 7 is formed inside the rim portions 3 and 3, and thus the front appearance of the glasses is almost the same as the conventional one. For this reason, the appearance of the glasses does not deteriorate significantly.
[0048]
And since the wall part is not provided in the width direction outer side part of the rim | limb parts 3 and 3, internal space is open | released by external air. Therefore, ventilation between the glasses and the face is performed, and fogging inside the lens can be prevented. Moreover, since it can be attached and detached just like conventional glasses, it is easy to use.
[0049]
Further, the rim portions 3 and 3 and the bridge portion 4 of the frame body 2 according to the present embodiment are formed of colored acetate resin, while the windshield portions 7 and 7 are formed of transparent acetate resin.
[0050]
By forming the windshield portions 7 and 7 from a transparent resin, the windshield portions 7 and 7 become inconspicuous. For this reason, the external appearance which the windshield parts 7 and 7 protrude from the rim | limb parts 3 and 3 can be eased, and design can be improved significantly.
[0051]
Moreover, since light enters the inner surface of the spectacles from the windshield portion and illuminates the face, it has the same appearance as when wearing normal glasses without the windshield portion. Therefore, it is less likely to give a strange feeling to those who meet.
[0052]
Further, as shown in FIGS. 3 and 5, a boundary groove 10 extending along the boundary portion is formed on the outer surface of the boundary portion at the upper edge portion of the rim portion 3 and the windshield portion 7. As shown in FIG. 5, the boundary groove 10 is formed in a V shape by cutting the windshield portion side made of transparent resin into a triangular cross section.
[0053]
By forming the boundary groove 10, the windshield portions 7 and 7 and the rim portions 3 and 3 can be clearly identified. For this reason, the rim parts 3 and 3 do not give a thick impression, and the windshield part is further inconspicuous. On the other hand, since the windshield portions 7 and 7 are made of a transparent resin, light is refracted at the boundary groove 10 and a kind of prism effect appears. This prism effect acts to make the width of the windshield portions 7 and 7 appear narrow. For this reason, the external appearance which is not in the past can be given, and the external appearance design of the frame body 2 is improved.
[0054]
Next, a method for manufacturing the frame body 2 will be described with reference to FIGS.
[0055]
First, as shown in FIG. 6, the colored acetate resin plate 11 and the transparent acetate resin plate 12 are integrally laminated using a solvent for welding the acetate resin to form a two-layer resin laminate 13. In the embodiment, a colored acetate resin plate 11 having a thickness of 8 mm and a transparent acetate resin plate 12 having a thickness of 7 mm are laminated and bonded to form a resin laminate 13 having a thickness of 15 mm. Since the two acetate resin plates 11 and 12 are joined by a solvent that dissolves the resin itself, they are also integrated in terms of the resin structure.
[0056]
Next, the resin laminate 13 is hot press molded using a mold (not shown). The hot press molding is performed in a heated state in which the temperature is raised above the deformation temperature of the resin laminate. Through this heat pressing step, the intermediate body 14 shown in FIG. 7 is formed.
[0057]
The intermediate body 14 is configured to include the contour of the frame body 2 to be cut out, and the frame body 2 is cut out by subjecting the intermediate body 14 to cutting or / and grinding.
[0058]
The form of the intermediate body 14 is shown in FIGS. As shown in these drawings, the intermediate body 14 has the colored resin plate 11 positioned at the rim cut-out portions 23 and 23 and the bridge cut-out portion 24, while the transparent resin plate 12 is disposed at the windshield cut-out portions 27 and 27. Heat press-molded so as to be positioned.
[0059]
By cutting the intermediate body 14 using a milling machine or the like, the frame body 2 shown in FIG. 14 is formed. In the final stage of the cutting process or in the finish grinding process, a boundary groove 10 is formed at the boundary between the rim parts 3 and 3 and the windshield parts 7 and 7 on the outer surface of the upper edge of the frame body 2. The boundary groove 10 is formed by cutting or grinding the windshield portions 7 and 7 side of the boundary portion into a V shape, and the surface is finished to be transparent.
[0060]
A nose pad portion 4 a is formed between the left and right windshield portions 7 and 7. The nose pad portion 4a is formed by cutting the resin between the left and right windshield portions 7 and 7 into a concave shape corresponding to the outline of the nose. Therefore, the airflow does not flow into the inside of the glasses from the gap between the nose pad portion 4a and the face, and the wind avoidance function of the windshield portions 7 and 7 can be enhanced.
[0061]
The scope of the present invention is not limited to the above-described embodiment. In the embodiment, the colored acetate resin plate and the transparent acetate resin plate are laminated and joined, and the frame body 2 is formed by integrally cutting the plate, but the rim portions 3 and 3 and the bridge portion 4 and the windshield portion are formed. 7 and 7 can be separately formed and then bonded by adhesion to provide a windshield portion.
[0062]
In the embodiment, the concave nose pad is provided between the left and right windshields, but a conventionally used nose pad may be provided separately. It is desirable that the height of the nose pad is adjustable so that the edge of the windshield can be held in contact with the face.
[0063]
In the embodiment, the intermediate body is formed from a laminate in which two acetate resin plates are joined. However, the intermediate body can be formed from a laminate in which three or more acetate resin plates are joined.
