Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to eyeglass frames.

[0002]

[Problems to be solved by conventional techniques and devices]

 Conventionally, nosepieces have been provided on eyeglass frames to prevent the positional displacement due to the weight of the eyeglasses and the vertical and horizontal displacement due to the vibration of the face by contacting both sides of the nose slightly closer to the base. One is provided on each of the two lens frames of the spectacle frame body. However, even the above-mentioned conventional eyeglass frames cannot completely prevent the positional deviation of the eyeglasses. That is, there is a space between the left and right nose pads of the above-mentioned conventional eyeglass frame that does not contact any part of the nose, but the human nose is soft except for a small part with the nasal bones. If the nose pads are kept in contact, if the glasses are very heavy, the tops near the base of the nose will be placed in the space between the two nose pads while narrowing the width of the nose when the glasses are very heavy. The glasses will slip forward and downward as if they are pinched.

In the above cases, specifically, the distance between the apex of the cornea and the center of the lens is changed, and when the lens is a thick lens with many aberrations, the image appears to be extremely distorted. Will end up. As a result, for example, a person with extreme visual impairment (eg, amblyopia) who uses a thick lens with many aberrations may have a harmful effect in daily life, and is of course very preferable from the viewpoint of the protection of visual acuity. Absent. Further, for a person who uses a thick and heavy lens, the weight of the lens may cause the eyeglasses to slide forward and downward, which may cause temporary inability to be seen, which may pose the same danger as the above-mentioned visual impairment. Further, for a person with a low nose such as an infant, the glasses are likely to slip off or move easily, and the same harmful effects as described above occur.

On the other hand, if the nose pad of the glasses is brought into contact with the part of the face where the nasal bones are present, it is possible to prevent the glasses from slipping down to some extent. I can't wear it for a long time with the same wearing posture.

In addition, when the user vibrates his face violently, no matter how he wears the glasses, he or she may go up, or the glasses may be slightly misaligned and the position of the glasses may be stable. In some cases, the same adverse effect as described above is brought about.

[0006]

[Means for Solving the Problems]

 The present invention has been made in order to solve the above-mentioned problems of the conventional technology, and the nose pad portion closely fits the nose of the person to be used to check the weight of the glasses and the presence or absence of vibration of the face. An object of the present invention is to provide a spectacle frame that can be worn regardless of discomfort when wearing glasses at a predetermined position on the face. That is, according to the present invention, the whole of the spectacle frame main body is close to the nose contact portion, and is near the base of the nose of a person, which is the lowest portion, and the entire upper part of the spectacle frame is attached to the spectacle frame. It is thicker toward the side and thinner toward the bottom, and the central part is thinner from the left and right sides over the top and bottom and is recessed with respect to the side to which the glasses are attached. It is characterized in that it is provided with a nose pad member that can substantially adhere in a planar manner from the top of the nose at the low height portion to both sides.

Further, the spectacle frame of the present invention comprises a spectacle frame body and a plurality of nose pads having different shapes and heights. It is thicker and thinner toward the bottom, and the central part is formed thinner from the left and right sides over the top and bottom, and it is recessed with respect to the side to which the glasses are put, and the lowest part near the base of the human nose. Of the nose of the eyeglass frame body is configured so that it can be adhered in a planar manner from the top to both sides of the nose, and is configured separately from the eyeglass frame body, and any one of a plurality of the eyeglass frame body is attached to the eyeglass frame body. It is characterized in that it is configured so that it can be fixed near the site corresponding to the nose contact and near the site of the lowest height near the root of the human nose.

In the spectacle frame, when the nose pad member is formed separately from the spectacle frame body, the nose pad member is a portion that directly contacts the nose, and It may be composed of one or more piece-shaped pedestal portions that can be fixed to the back surface side.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The drawing shows one embodiment of the present invention, and FIG. 1 is a partial perspective view showing an example of the eyeglass frame of the present invention.

The mega frame 1 of the present invention is, for example, as shown in FIG. 1, in the vicinity of the nose-contacting portion of the spectacle frame body 2 and a bridge 4 connecting both lens frames between the left and right lens frames 3, 3. To the sides of the nose on both sides of the nose, which corresponds to the lowest part near the base of the nose of a person, in a U-shape (usually in the Cam mountain style) when viewed from the front. The thickness of the central part 6 is thinner than that of the left and right side parts 7 and 7, and the central part 6 is thinner than the left and right side parts 7 and 7 in the vertical direction. The nose is recessed with respect to the side to which the eyeglasses are attached, and it is possible to form a substantially planar contact from the top of the nose at the lowest height near the base of the human nose to both sides. A pad member 8 is provided.

The nose pad member 8 is formed in such a shape and height that the distance between the center of the lens and the apex of the cornea of the eye is about 12 mm when the person wears the eyeglasses using the eyeglass frame 1. Is preferred. This value of 12 mm is a reference value required for glasses for the visually impaired.

The nose pad member 8 may be integrated with the spectacle frame main body 2 from the beginning, or may be a separate body from the spectacle frame main body 2 at the beginning, and is fixed and integrated with the spectacle frame main body 2 by means such as adhesion. May be.

As the material of the spectacle frame body 2 and the nose pad member 8, for example, various metals such as titanium-coated metal, various plastics such as celluloid, and the like used in conventionally known spectacle frames can be used. The material may be the same or different, but if the above two are bonded and integrated by an adhesive, plastic is preferable, and the same kind of plastic, for example, cellulose is preferable. As the adhesive used for the adhesion, among the conventionally known adhesives, any adhesive can be used as long as it can ensure the adhesion without destroying the materials of the both.

In the present invention, when the person wearing the glasses using the spectacle frame 1 wears the nose pad member 8, the top of the nose and the both sides of the nose of the lowest height near the base of the nose of the person wearing the glasses are covered. The shape is not limited to the above-mentioned shape as long as the shape can be closely attached to the armpit. For example, as the shape of the nose pad member 8 other than the above, as shown in FIG. 2, it is a substantially one-letter shape in a front view (usually referred to as a single mountain style) and a normal single mountain style nose contact portion, Alternatively, the vertical width is slightly wider (w direction in the figure) than that of a normal bridge, and the upper part is thicker toward the eyeglasses-mounted surface side and the lower part is thinner, and the central part 6 is located vertically. It may be formed to be thinner than the left and right sides 7 and 7 and to be recessed toward the side to which the glasses are attached.

As shown in FIG. 3, the spectacle frame 1 of the present invention includes a separate nose pad member 8 and a plurality of nose pad members 8 having different shapes and heights (length in the h direction in the figure). Prepare the back side 9 of the nose pad member 8 near the nose contact portion of the spectacle frame body 2 from the bridge 4 that connects the left and right lens frames 3 and 3 to each other. It can also be configured so that it can be fixed near the parts corresponding to both sides corresponding to the part 5 and corresponding to the lowest part near the base of the nose of a person. In this case, of course, a plurality of nose pad members 8 are substantially in contact with each other in a planar manner from the top of the nose of the lowest part near the root of each nose of various people to both sides. It has such a shape and height as possible.

About several types are suitable as the types relating to the shape of the nose pad member 8 prepared in advance, and in terms of the shape, statistically, if there are three types of nose pad members, 95% of the nose pads will be used. The shape can be covered. The remaining 5% can be covered by partially polishing the nose contact portion of the nose pad member 8 with sandpaper or the like. Thus, since the nose pad member is independent, fine adjustment of the shape such as partial polishing is easy.

If there are too few types of nose pads regarding the shape, it is not possible to deal with various nose shapes (that is, various people), and if there are too many types of nose pads, the manufacturing cost increases. Is not preferable.

When using the spectacle frame 1 described above, as the means for fixing the nose pad member 8 to the spectacle frame body 2, the same method as described above can be adopted.

As described above, the nose pad member 8 is provided separately, and a plurality of nose pad members 8 having different shapes and heights (length in the h direction in the figure) are prepared, so It is possible to select and use any one of the nose pad members 8 that suits the shape and height of the nose of the person, so that one spectacle frame body 2 can be used for various nose shapes and heights. It can be widely used by people, and when selecting the nose pad member 8 that matches the shape of the nose, the nose pad member 8 alone does not have to be fitted with the nose pad member 8 mounted on the eyeglass frame body 2. Since it can be selected with, the shape can be adjusted easily.

In the spectacle frame 1 of the present invention, when the nose pad member 8 is formed as a separate body, as shown in FIG. 4, the nose pad member 8 and the nose pad portion 8 1 which directly abuts the nose. Also, it may be configured with one or more pedestals 82 for adjusting the height. In this case, the nose pad 81 can adopt the shape, length, and width of the nose pad member 8 when the pedestal 82 is not used. Regarding the height (length in the h direction in the figure), only one kind of shape, length, and width needs to be prepared, but it is better than the nose pad member 8 when the pedestal portion 82 is not used. It is better to form it slightly lower. If the height is slightly lower, it can be applied to people with a low nose. The pedestal portion 82 is composed of a thin piece having the same shape as the back surface 9 of the nose pad 81, and is attached to the back surface 9 side of the nose pad 81.

The thickness t of the pedestal portion 82 is appropriately about 1 mm to 2 mm, but is not limited thereto.

As a means for attaching the pedestal portion 82 to the back surface 9 of the nose pad portion 81, any method such as attachment with an adhesive can be adopted. Of course, the pedestal portion 82 is near the nose contact portion of the spectacle frame body 2, and the portion from the bridge 4 connecting both lens frames between the left and right lens frames 3 and 3 to both side portions 5 of the nose. However, it is possible to fix it in the vicinity of the part corresponding to the lowest height part near the base of the human nose. Various methods such as the above can be adopted.

When the nose pad 81 and the pedestal portion 82 are adhered to each other with an adhesive, the material of the nose pad 81 and the pedestal portion 82, and the adhesive for adhering them together are the nose pad member 8 and This is the same as when the eyeglass frame body 2 is bonded.

When the nose pad member 8 is configured as described above, the height of the nose pad member 8 is adjusted so as to correspond to the height of the nose of the person wearing the glasses configured using the glasses frame 1. Since the shape can be changed freely, in addition to the above-described shape adjustment being easy, the spectacles user can increase the pedestal portion 82 one by one until the height is suitable for the user himself. The height can be freely adjusted by mounting it, and various nose heights can be accommodated by only one type of nose pad 81. Moreover, the height can be adjusted simply by increasing the number of the pedestal portions 82 one by one and sequentially fixing the pedestal portions 82 to the back surface of the nose pad portion 81 or the spectacle frame body 2 so that the adjustment can be performed easily.

Next, the operation of the eyeglass frame of the present invention will be described with reference to FIG. The figure shows a state in which eyeglasses are attached, (a) is a side view of the eyeglasses attached state, and (b) is a perspective view. As shown in the figure, when a person wears eyeglasses using the eyeglass frame 1, the center portion 6 of the nose pad member 8 provided in the eyeglass frame body 2 is located near the base of the nose 10 of the person. It comes into contact with the apex 11 of the nose at a low height and is slightly caught by the lower nasal bone and the upper forehead bone, and does not move easily in the vertical direction (the direction of arrow a in the figure). Also, the left and right side portions 7, 7 of the nose pad member 8 abut on both side portions 12, 12 of the nose near the base of the human nose 10 and do not easily move in the left and right direction (direction of arrow b in the figure). . Needless to say, if the vine of the glasses (the part from the base of the handle to the tip of the ear hook) has an appropriate length, the glasses will not move to the front of the face. Of course, the central portion 6 and the left and right side portions 7, 7 of the nose pad member 8 are not in point contact with the above-mentioned 11, 12 but rather extend from the central portion 6 to the left and right side portions 7, 7. The entire surface is in contact with the entire surface from 11 to 12, 12 so as to be in close contact with the entire surface. Therefore, the pressing force applied to the contact surface is also weak.

[Effect of device]

 As described above, the spectacle frame of the present invention is near the nose contact portion of the spectacle frame main body, near the position corresponding to the lowest height near the base of the nose of a person, It is thicker on the side where the glasses are attached and thinner toward the bottom, and the central part is formed thinner from the left and right sides over the top and bottom, and is recessed toward the side where the glasses are attached. Since the nose pad is provided so that it can be in close contact in a planar manner from the top of the nose at the lowest height near the base to both sides, the base of the nose of the human being used. Since the nose pads of the glasses closely adhere to each other in a planar shape in the vicinity, the glasses fit closely to the base of the human nose, allowing the glasses to be worn comfortably in place on the face. Have. Also, the eyeglasses fit closely to the base of the human nose, so the glasses do not move easily and should be kept in place on the face regardless of the weight of the glasses and the presence or absence of vibration of the face. Yes, and therefore the distance between the corneal apex and the center of the lens can be kept constant, which is extremely useful for protecting eyesight, especially for people with extreme amblyopia who use thick lenses with high aberrations. It is advantageous. It is also advantageous for those who use thick lenses, because the weight of the lenses does not cause the glasses to slip forward and downward. Further, it is advantageous for a person with a low nose such as an infant, in particular, that the nose pad member is brought into close contact with the lowest part of the nose to prevent the glasses from slipping off. For a person who corresponds to a composite case of the above various cases, each advantage in each of the above cases can be obtained.

The spectacle frame of the present invention comprises a spectacle frame body and a plurality of nose pads having different shapes and heights. On the other hand, it is thicker and thinner toward the bottom, the central part is vertically thinner from both left and right sides, and is recessed with respect to the eyeglasses-mounted surface side. It is constructed so that it can be closely adhered in a planar manner from the top of the nose of the lower part of the eyeglasses to both sides, and is configured separately from the eyeglass frame body and any one of the plurality of eyeglasses can be attached to the eyeglasses. Since it is configured so that it can be fixed near the part of the frame body that corresponds to the nose contact and the part that corresponds to the lowest height part near the root of the human nose, one eyeglass frame body can be used. Various nose shapes It can be widely used by people of all heights and heights, and when selecting a nose pad that fits the shape of the nose, the nose pad must be attached to the main frame of the eyeglass frame without matching. Since it can be selected with, there is an advantage that the shape can be easily adjusted.

In the present invention, the spectacle frame includes a spectacle frame main body and a plurality of nose pad members each having a different shape and height, and the nose pad member is configured separately from the spectacle frame body. It is configured such that any one of a plurality of pieces can be fixed near the part corresponding to the nose contact of the eyeglass frame main body and near the part corresponding to the lowest height near the root of the nose of a person. In the case where the nose pad member is composed of a nose pad part that directly contacts the nose and one or more piece-like pedestal parts that can be fixed to the back side of the nose pad part. Since the height of the nose pad can be freely changed so as to correspond to the height of the nose of a person wearing eyeglasses, which is configured using an eyeglass frame, in addition to the above-mentioned simple adjustment, Height point Then, you can adjust the height freely by increasing the pedestal part one by one until you reach the height that suits you, and you can adjust the height freely. Only one type of nose pad supports various nose heights. can do. Moreover, there is an advantage that the height can be adjusted simply by increasing the number of pedestals and mounting them one by one.
