Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is an improvement of the Krings-type eyeglass frame. Specifically, after the frame adjustment for the wearer is completed, the pad surface of the nose pad is adjusted to an angle suitable for wearing. This invention relates to Krings-style glasses that can maintain their settings.

[Conventional technology and problems to be solved]

Holder boxes 5 are provided at the ends of a pair of left and right linear arms 4 extending from positions near both sides of the bridge 3 of the front frame 2, and the joint plugs 7 of the nose pads 6 are inserted into these holder boxes 5. The Krings-type eyeglass frame, which is supported by screw 8, is conventionally well known.
Today, it has come to be widely used in metal eyeglass frames because it can easily fit any nose bridge surface that varies widely depending on the individual wearer.

However, in the case of such conventional Krings-type eyeglass frames, the nose pads 6 are attached so that they can swing loosely, so when the glasses frame is worn, the position of the nose pad 6 may not be adjusted to the appropriate position on the face. Even if the nose pads 6 are not bent, the nose pads 6 conform to the bridge of the nose, which tends to cause a mismatch between the optical axis of the lens and the visual axis of the wearer, often causing eye strain.

The present invention was developed in an attempt to eliminate the above-mentioned drawbacks of conventional Klings eyeglass frames.After adjusting the frame for the wearer, the pad surface of the nose pad is set and held at the optimal position on the bridge of the wearer's nose. By doing so, we aim to provide a highly practical Krings-type eyeglass frame that allows the optical axis of the lens to match the visual axis and, by going one step further, constantly maintains an appropriate distance between the lens surface and the cornea. This is the purpose.

[Technical means adopted to achieve the objective]

The means adopted by the present inventor to achieve the above object will be explained below with reference to the accompanying drawings.

That is, in the present invention, holder boxes 5 are provided at the tips of a pair of left and right linear arms 4 extending from positions near both sides of the bridge 3 of a front frame 2 having a pair of left and right rims 1. The conventionally well-known Krings-type eyeglass frame in which the joint plug 7 of the nose pad 6 is inserted and supported by screws 8 has been improved by adding a plastic rocking prevention plate 9 to the connecting portion between the holder box 5 and the nose pad 6. By adopting technical means of intervening,
It is possible to set the pad surface 61 of the nose pad 6 to a required angle.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on illustrated embodiments.

The Krings eyeglass frame to which the present invention is applied has a structure in which a nose pad 6 is fixed to a holder box 5 at the tip of a linear arm 4 with a screw 8 at a joint plug 7. However, it goes without saying that the specific shapes of the holder box 5, the joint plug 7 of the nose pad, and the screws 8, as well as their connection relationship with each other, can be modified in a conventional manner.

In the present invention, a plastic rocking prevention plate 9 is interlocked between the nose pad 6 and the holder box 5 in the Krings type eyeglass frame having the above-described structure. For example, Fig. 2, Fig. 4
Although plastic packing having a joint insertion hole 91 as shown in FIGS. It is sufficient to intervene in order to prevent instability between the two.

[Effects of this invention]

As explained above with the embodiments, in the case of the Krings-type eyeglass frame to which the present invention is applied, it is possible to prevent the pad surface 61 of the nose pad 6 from swinging while the pad surface 61 is set at the required angle, so that it is possible to prevent the pad surface 61 from swinging. In this case, the pad surface 61 of the nose pad 6 settles at a suitable position on the nose bridge surface according to the preset angle, so that the optical axis of the lens and the visual axis of the wearer correctly match, and the distance between the corneas is also appropriate. It will be kept as follows.

As described above, according to the present invention, it is possible to solve all of the above-mentioned wearing problems that were considered to be difficult points in the conventional Klings style glasses frames. Since it is only necessary to insert a plastic rocking prevention plate between the nose pad and the holder box during adjustment, the structure is simple and can be provided at low cost.

Claims (1)

[Scope of utility model registration request] A front frame 2 having a pair of left and right rims 1
A holder box 5 is installed at the tip of a pair of left and right linear arms 4 extending from positions near both sides of the bridge 3.
In the Klings-type glasses frame, in which the joint plug 7 of the nose pad 6 is inserted into the inside of these holder boxes 5 and supported by screws 8, a plastic rocking prevention material is installed at the connecting portion between the holder box 5 and the nose pad 6. This pad angle setting structure is characterized in that a pad surface 61 of a nose pad 6 is set at a required angle by interposing a plate 9.
