Lens mounting structure of eyeglass frame

Abstract

Provided is a lens mounting structure of an eyeglass frame. According to the structure, a lens is hard to release even a front frame of a half-lens circle type or an eyebrow bar type is applied with force and impact in a bending direction; and good view can be obtained even the front frame employs a resin frame or a wooden frame. The structure at least comprises front frames (1) of a half-lens circle type or an eyebrow bar type located on left and right sides to connect lens legs (T,T) and possessing a lens circle cover (11) forming an inner groove (11a) and an inner lens circle (2) which is inserted into the inner groove (11a) of the lens circle cover (11) of the front frames (1). Furthermore, in the inner groove (11a) of the lens circle cover (11) of the front frames (1), a recess part (11b) with a deeper local terrain than that of the inner groove (11a) is provided; and a protruding part (21) is arranged at a prescribed position on the inner lens circle (2) and can be in fixed connection with the recess part (11b) when the protruding part (21) is inserted into the recess part (11b).

Description

technical field [0001] The present invention relates to an improvement of a lens mounting structure of a spectacle frame. Specifically, it relates to a lens that is difficult to come off even when a force or impact in a bending direction is applied to a half rim type or brow bar type front frame. Furthermore, even when a resin frame or a wooden frame is used as the front frame, it is possible to obtain a lens attachment structure of a spectacle frame with a good field of view. Background technique [0002] As we all know, the installation method of the lens relative to the spectacle frame varies greatly due to the presence or shape of the rim (full rim type, half rim type, no rim type), among them, as far as the half rim type glasses are concerned, generally A method in which a cord is wound around a groove formed around the lens and both ends are fixed to the front frame (so-called half-rim glasses). [0003] However, in the method of fixing the lens with a cord, since the...

Problems solved by technology

[0006] But, because the spectacles of the above-mentioned document is the structure that connects the inner frame on the back of the bridge of the nose of the front frame, so, in the case of using a resin frame or a wooden frame having a relatively large thickness for the front frame, since the inner frame The upper lens is placed at the deepest part, and the front frame narrows the field of view, so there may be cases where a good field of view cannot be obtained

[0007] On the other hand, instead of making the above-mentioned left and right mirror rings into one body, the technology of fixing and connecting each mirror ring under the front frame respectively is also known (see Patent Documents 3 to 5). However, these technologies In other words, since the fixed connection components are fitted by unevenness and attracted by magnets, there is also the possibility that the lens and even the lens ring will fall from the front frame due to a slight impact.
