Description

[0001] The present invention relates to a nose support for the spectacles,

More particularly, the present invention relates to a spectacle nose coupling connector, and more particularly, a connecting piece connecting the left and right eyeglass frames is provided with a plurality of mutually different lengths, and the selected connecting piece is coupled to the nose coupling connector to fix the left and right eyeglass frames The distance between the left and right lenses can be easily set according to the user and the nose connecting port is fixed at the upper and lower portions at predetermined intervals when fixing the spectacle frame to prevent the nose connecting port from flowing, And also to a spectacle nose coupling connector capable of improving the merchantability.

In general, in order to improve the fit of the eyeglass frame and to secure the distance between the inner surface of the spectacle lens and the eyelashes of the human body, the inner side of the rim constituting the spectacle frame or the inner side of the bridge connecting the rim and the rim, Thereby forming a nose support.

Such nose supports vary in shape depending on the type and material of the frame, and generally can be classified into an integral nose support, which is mainly seen in synthetic resin frames, and an assembled nose support, which can be seen in metal frames.

In the case of the integral nose support, the nose nose protrudes at a certain shape and height on the inner side of the rim during the injection molding process of the synthetic resin eyeglass frame, thereby achieving high productivity and reducing the production cost. It is not possible to arbitrarily adjust the width and height of the nose support, and in order to form the nose support having different shapes and heights, the design of the whole eyeglass frame has to be renewed , There was a burden to newly manufacture an injection mold for manufacturing an eyeglass frame.

On the other hand, in the case of the assembled nose receiver, the connecting leg is welded to the inside of the rim of the frame made of metal mainly to integrally form the nose, and then the nose receiver made of silicon is screwed to the joint portion formed at the end of the connecting leg Such an assembled nose support is advantageous in that it can be easily adjusted to the height and width of the nose of the wearer after the installation of the eyeglass or eyeglass of the connecting leg is arbitrarily bent. However, the connecting leg must be individually welded to the inside of the rim of the eyeglass frame Therefore, productivity is lowered and manufacturing cost is increased.

In addition, the conventional eyeglasses can not be properly set according to the user because the connecting piece provided to connect the left eyeglass frame and the right eyeglass frame is fixed and the length thereof can not be adjusted.

In order to solve this problem, there have been disclosed a plurality of structures capable of adjusting the length of a connecting piece, but the structure is complicated and substantially difficult to apply to glasses. That is, since the difference in the distance between the eyes of the human eye is minute, it is only necessary to finely adjust the left and right spectacle lenses without much adjustment. However, since this is practically impossible, glasses were conventionally manufactured according to the standard.

However, when the wearer wearing glasses wears the glasses due to a slight difference, they are not fit to the eyes and easily feel fatigued.
