Problems solved by technology

[0002] In order to reduce the space occupied by the glasses and make them easy to carry, the existing technology is to perform multiple folding operations on multiple folding mechanisms provided on the bridge of the nose and the leg frame of the glasses. For example, the Chinese patent was announced in December 1991 ZL91210594 announced in October 2002, ZL97112574 announced in October 2002, ZL01210683 announced in June 2002, etc. Although the folding methods are different, there is a problem that the operation process of folding and unfolding is more troublesome. The method of supporting the size to reduce the gap between the two lenses after folding, so the structure after folding is not compact enough
The solution provided by ZL91210594 adopts a structure in which two pivots are installed on the bridge of the nose to divide the bridge of the nose into three sections for folding because of the shape of the lens and the folding direction, which makes the structure of the glasses unstable after folding, and the gap between the two lenses The gap is large, and the ability to resist accidental extrusion damage is low.

example 1

[0020] Spectacle frames are made of metal. Such as figure 1 As shown: the frame 2 together with the lens 3 is connected to the bracket 7 through the pivot 6 mechanism. The lens looks like an inverted O-shape, and the bracket looks like an inverted U-shape. The connection is in the middle of the O-shape and the U-shape. It is divided into two parts with the same structure, which are located on the opposite sides of the frame and the bracket. The two parts are pivoted. The center line is the same straight line. Figure 3 shows the structure of one part of the pivot 6 mechanism: the shaft seat 11 is connected with the mirror frame 2 as a whole, the pivot is welded on the shaft seat, the bracket 7 has a hole as a bearing, and the pivot 6 passes through the hole and is riveted on the On the bracket. The bracket 7 is connected with the leg frame 5 through the pivot 4 mechanism, and the connection is also divided into two parts, the structure is as follows Figure 8 As shown: the sh...

example 2

[0026] Such as Figure 10 and Figure 12 As shown, the lens 3 is connected to the bracket 7 through a pivot 6 mechanism. The support is C-shaped, and one end is connected with the nose pad 8, and the other end is connected with the leg frame 5. The shaft seat 11 of the pivot 6 is connected with the bridge of the nose 1 as a whole, and is connected with the lens 3 through a rivet, and the structure of the riveted part is the same as that of the existing commercially available glasses. The pivot 6 is welded on the shaft seat 11, and is riveted on the bracket 7 through the hole on the bracket, which is basically the same as shown in FIG. 3 . The leg frame is a folding type with a pivot mechanism in the middle, which is the same as the existing commercially available glasses. The structures of the pivot mechanism in the middle of the bridge of the nose, the pivot mechanism at the junction of the bracket and the leg rest, and the pivot mechanism in the middle of the leg rest are a...

Abstract

This invention is a kind of spectacles that can fold and stretch. The two lens or frames are connected by pivot mechanism. The two brackets are connected with leg brackets by pivot mechanism. The two lens or the two frames are connected by the bridge that has pivot mechanism. The lens and brackets reel the pivot between them rotate to different directions in the process of folding or stretching. The operation of folding or stretch becomes easy in this way. The structure is compact and convenient to carry. It also can stretch leg brackets when folding the two lens, make it one operation from fold state to unfold state, especially suit for the spectacles like presbyopic glasses that need instant folding and unfolding.

Description

technical field [0001] The present invention relates to spectacles, especially a kind of collapsible spectacles. Background technique [0002] In order to reduce the space occupied by the glasses and make them easy to carry, the existing technology is to perform multiple folding operations on multiple folding mechanisms provided on the bridge of the nose and the leg frame of the glasses. For example, the Chinese patent was announced in December 1991 ZL91210594 announced in October 2002, ZL97112574 announced in October 2002, ZL01210683 announced in June 2002, etc. Although the folding methods are different, there is a problem that the operation process of folding and unfolding is more troublesome. The method of supporting the size reduces the gap between the two lenses after folding, so the structure after folding is not compact enough. The solution provided by ZL91210594 adopts a structure in which two pivots are installed on the bridge of the nose to divide the bridge of t...
