Description

  The present invention relates to an eyeglass frame, and more particularly to an eyeglass frame with an improved temple of an eyeglass frame.

Glasses are so familiar to humans that they are said to be part of the body, and the frames that are the main constituents of glasses have been provided with a wide variety of frames that can be said to be infinite from any functional and visual point of view. ing.
The wide variety is difficult to illustrate and is insignificant.

  Despite the availability of so many eyeglass frames, there is still room for improvement in eyeglass frames. It is a very sensitive and subtle element because glasses are attached to the human body (face) in direct contact, and directly affect and affect the basic human sense of vision. It is thought that the main reason is that it is necessary.

The glasses are basically composed of (two) lenses and a frame for mounting and holding the lenses so as to be positioned in front of the eyes.
More specifically, the frame is more generally composed of a rim, a bridge, a wisdom, a hinge, a temple (including modern), and a pad. This configuration is universal for most eyeglass frames. In this specification, a temple is a member whose tip is connected to a hinge attached directly to a lens, a rim (any rim such as brow bar, nyroll, half rim, two-point, under rim) or a lens in a spectacle frame. To the rear end of the ear. The cell is a separate member.

The primary function of the frame is to accurately position the lens at the optimal position (called the eye point) with respect to the line of sight of the eye, and correct the lens without changing as much as possible, whenever possible. It is desirable to hold it in position.
At the same time, since it is directly attached to the human body as described above, it is strongly required to be comfortable to wear and fit.
Glasses frames are required to satisfy these simultaneously.

  Except for glasses intended for decoration or temporary wear, glasses that have functions such as normal vision correction are equipped with a lens attached by a technician with appropriate skills. The lens is adjusted so that the lens is mounted at a proper position on the face with a good wearing feeling so that the lens can be in a proper position where the eye point is captured and the required function of the glasses can be performed.

However, at the beginning of such proper adjustment, the person wearing the glasses or the person's face is constantly moving, even if the glasses were adjusted once so that they can be positioned accurately. The position of the eyeglasses or lens is quickly shifted from the proper position. Most often, the lens part slides down below the face.
Such misalignment is not preferable for single-focus lens glasses, but is not preferable for far-near multifocal lens glasses.

Therefore, in actual use, the user of the glasses must frequently adjust the position of the glasses on the face.
However, the position adjustment is not a full-fledged position adjustment by an expert, but is performed by an amateur user just in time during use. Glasses are used in an inappropriate position with a point shift.

Use in an inappropriate position may not only provide sufficient vision, but may also lead to a dangerous situation that may lead to an accident, especially for a multifocal lens eyeglass user.
Although it is not impossible to wear glasses whose position is fixed on the face, such glasses are expected to be very painful and inconvenient for the user, and are impractical.

In the conventional spectacle frame, there has been no structure that can easily and accurately adjust and select the appropriate position during use.
Patent Documents 1 to 4 disclose devices for adjusting the elevation angle and depression angle of the lens with respect to the temple in the spectacle frame in advance. However, the angle adjustment for the entire spectacle frame of the lens is stopped. As a result, the position can be easily and easily adjusted at any time, and the displacement of the glasses frame after adjustment is not reduced.

  In other words, in the conventional spectacle frame, any adjustment of the position of any spectacle frame does not simply give the degree of lens angle adjustment, and the fundamental adjustment to adjust the position of the entire spectacle frame is not possible. Therefore, the position shift is repeated immediately, and the fact that the position adjustment must be repeated frequently is not solved, and it is not necessary to easily and accurately match the eye point.

  In view of such a background, the present invention can adjust the positional relationship between eyeglass lenses and eyes, that is, so-called eyepoints, at any time, even if the user is a general eyeglass user who does not have glasses skills. It is to provide a spectacle frame that can be easily and accurately performed by the user.

The present invention provides a spectacle frame in which a temple is provided with joint means that bends the temple in the vertical direction and holds an arbitrary predetermined bent form (angle).
At least one joint means is provided.
There are no particular restrictions on the number of joint means and the places where the joint means are provided. A temple with a very long modern, i.e., a temple extending long near a hinge, may be provided at a location in the modern, but in such a case, it is a problem to select appropriately depending on the correlation with the long modern function. .

The joint means may be provided at a plurality of locations. In that case, if one joint device is provided at a location close to the modern location, more suitable adjustment is possible.
It can be said that the number of joint means and the places where the joint means are provided are preferably the same number and the same place (contrast place) in the left and right temples. However, it goes without saying that the left and right temples may be different regardless of the number of joint means. However, if the number and location of joint means is different, it will be changed according to the characteristics of the user, and it will be made to order, so it is not common, but even in such a case, it is within the scope of the present invention. It remains the same.

The articulating means may be any conventional means.
However, any means needs to be fixedly and rotatably connected so that the bent state is maintained when the temple is bent. For this purpose, any conventional means such as caulking may be used.
As the joint means, for example, the joint means may be simply crimped with a scissors or the like at the place where the joint means is provided, where the temples are divided and the tips are partially overlapped. In that case, it is preferable to reduce the thickness of the overlapped portions and overlap the portions.

Further, the joint means may be such that the temple is divided, and both ends of the divided portions are opposed to each other with a predetermined interval and are pivotally attached to the bridge pieces of different members.
In this case, the bridge piece may be a single-leaf plate, or a single plate may be folded into a U-shaped cross-section and sandwiched from both sides to be pivotally attached to each tip. Good.
The wider the gap between the opposing portions of the temple, the more the temple can be bent at a larger angle.

In addition, the bending angle of the temple can be increased by cutting out the upper and lower corners of the two opposing portions. Forming the tip in an arc shape is one means.
When the bridge piece has a U-shaped cross section, the bent range of the temple becomes large if a part corresponding to the bottom of the lower or upper side of the open state is cut out for a certain length.
The use of a bridge piece for the joint means is an example, and equivalent conventional means can be used.
The joint means is preferably provided with a click means. There are many modes for the click means, but any click means can be used.

In the case of crimping or the like, the bending angle of the temple can be bent steplessly, but when the click means is provided in the joint means, the temple can be bent stepwise.
It is not necessary to specify in either case.
The temple of the eyeglass frame according to the present invention bends only in one plane in the vertical direction.
The temple of the present invention is not easily bent and deformed not only in the vertical direction but also in the front-rear direction, that is, in three dimensions.

The degree of bending of the temple, the position of the bending, and the like may be selected and executed by the user so that the user can obtain the most suitable state at that time.
Even the glasses frame of the present invention may be used in the same way as ordinary glasses without bending the temple at all, and the joint means for bending does not necessarily have to bend the same part to the same extent in the left and right temples. .
For example, even in the case of a spectacle frame in which a joint means is provided for each temple, only the left or right joint means may be bent, or the left and right joint means may be bent at different degrees. Is.

By bending the temple, the depth of the glasses, that is, the distance between the lens (or pad) and the modern surface may become too short, and the glasses may not be suitably worn. In order to solve the problem in that case, a conventionally known temple length adjusting means may be additionally provided.
The spectacle frame of the present invention is most suitable for use in spectacle frames for multifocal lenses such as spectacles for correcting vision, especially for bifocal glasses, but for correcting vision. The present invention is also suitably applied to other decorative purposes such as sunglasses. In the case of sunglasses, the present invention can be most effectively applied to a lens sunglasses that changes the shade of color.

  According to the spectacle frame of the present invention, the position of the eyeglass frame is shifted due to misalignment during use, especially when the spectacle frame is loosened due to continued use of the eyeglass. Even if you are not a person with specialized skills, you can easily and accurately correct the user at any time, and it will not adversely affect the feeling of fitting and fitting. It is possible to secure a state in which the glasses can be used properly while maintaining good.

Moreover, in the glasses frame of the present invention, the position of the glasses frame is not changed again immediately after the position is adjusted by the joint means, so that the position can be maintained stably for a long time, so that the position is adjusted frequently as in the case of the glasses frame so far. There is no need to do.
Further, the spectacle frame of the present invention is particularly advantageous in spectacle frames for so-called multifocal lenses such as bifocal lenses and sunglasses of lenses that change the color shade.

  It is a perspective view of the spectacles frame of the present invention.   It is explanatory explanatory drawing which shows the joint means of the spectacles frame of this invention.   It is a figure which shows the use condition of the spectacles frame of this invention.

FIG. 1 is a perspective view of a spectacle frame of the present invention.
The illustrated eyeglass frame is provided with two joint means on each of the left and right temples.
In the figure, 1 is an eyeglass frame, 2 is a temple, 3 is a joint means, 4 is a lens, 5 is wisdom, 6 is a hinge, and 8 is a nose pad.
In this embodiment, joint means 3 are provided at two locations on one temple 2. The temples 2 on both sides are provided with joint means 3 at the same location, and the two temples are formed in contrasting shapes.

In this embodiment, the joint means 3 is provided as follows so that the temple 2 can be bent in a wide range in the vertical direction at the joint means 3.
The joint means 3 of this embodiment is shown in detail in FIG.
Both ends of the divided temple 2 are formed in a convex arc shape, and both ends are opposed to each other with a slight space therebetween, and the ends are pivotally attached to the bridge piece 11 via the pivot shaft 12. .
The bridge piece 11 is obtained by bending a thin plate into two thin layers and having a U-shaped cross section.
Both sides 13 and the lower side 14 of the bridge piece 11 are open.

The upper side 15 is connected only to the central portion, and both end portions are notched and opened.
The temple 2 that is pivotally connected is firmly but rotatably connected by the bridge piece 11, and can be rotated in a large range (angle) only in the vertical direction by opening the upper side and the lower side. Large bends are possible as a whole.
The bridge piece may be made of metal or plastic, for example. However, since a large load is applied, the bridge piece needs to be made of a material having a sufficient strength to withstand it.

FIG. 3 shows the joint means using the joint means 3 on the front side (the one closer to the lens) of the joint means 3 provided on the temple when the lens side of the glasses is shifted downward while using the eyeglass frame of the first embodiment. 3 illustrates the use state in which the front temple is bent upward from 3 and the lift lens is positioned upward. The temples on both sides were bent in the same state. The temple in a state where the deviation before the position adjustment has been dropped is indicated by a broken line.
After the position adjustment in this way, the glasses frame is less likely to immediately shift downward, and the need for position adjustment is reduced, thus eliminating the inconvenience for the user.
