Abstract

The utility model discloses foldable glasses, improved on the structure of the glasses frame and support. Because of adopting a foldable nose bridge, a multisection combined structure glasses leg which can be bended, rotated and flexed and the rotating shaft of the glasses legs, the rotating shaft of the glasses legs shows level condition, positioned at the connecting part of the glasses legs and glasses frame and is parallel to glasses lens, and therefore, the rear folded bulk of the foldable glasses is much smaller than the rear folded bulk of ordinary glasses, which is convenient for carrying. The utility model is especially suitable for the situation of wearing and taking off glasses frequently. For instance, sunglasses used for touring.

Description

Foldable glasses

The utility model belongs to the improvement of folding glasses framed structure.

General folding glasses framework, its mirror leg and picture frame all are one-piece construction, and the mirror leg rotating shaft of picture frame and mirror leg connection is in vertical state.No. 4367929 described glasses of patent of the U.S. have the sectional type mirror leg that is combined by foreleg and back leg.But picture frame still is a rigid unitary structure.These glasses are being received poststack with generally folding glasses is the same, and two eyeglasses are in the same plane, and length is bigger, carries inconvenience.

The utility model has been done improvement at above-mentioned shortcoming, picture frame is designed to two sections constitutes by an active connection; The mirror leg is connected and composed by multi-segment activity; The mirror leg rotating shaft of mirror leg and picture frame junction is the level of state and is parallel to eyeglass.

Nose bridge mechanism of the present utility model is as follows: be connected in nose end of the bridge (or the nose end of the bridge is the part of picture frame body) on the picture frame (see among Figure 12 1) and stretch in the nose axle housing (see among Figure 12 2), two xsects are that arc pad (see among Figure 12 3) is combined with the nose end of the bridge and formed diameter and the approximately equalised assembly of nose axle housing internal diameter.Two through holes are arranged on the pad.Axis hole on the nose end of the bridge and rotating shaft (see among Figure 12 4) cooperate.Being common centreline with same bus on the nose axle housing has the longitudinal opening groove of twice equal in length every a spacing, has the circular arc of the center of circle on the center line of groove on the twice groove, and its diameter is slightly less than the rotating shaft diameter.During assembling, earlier arc pad and nose end of the bridge are made up in the nose axle housing, turn nose end of the bridge aligns circular arc and axis hole.Again the arc hole is slightly firmly backed down in rotating shaft, put into axis hole, after rotating shaft entered axis hole fully, the elasticity of nose axle housing made the withdrawal of arc hole former big, guarantees that rotating shaft can not drop out.When the groove of nose axle housing was on the extended surface on nose end of the bridge plane, the nose end of the bridge just can have the one side of groove to rotate toward the nose axle housing around the shaft, and the nose bridge mechanism can be turned back.

Interval width between nose axle housing two grooves or the interval width between two rotating shafts should be designed to the unlikely interference that other position generation might make glasses damage on eyeglass or the glasses that makes.

Mirror leg shaft support (see among Fig. 9 1) is fixed on (maybe this supports the part into the picture frame body) on the picture frame, and mirror leg head (see among Fig. 9 3) is gone up tape spool hole planar ends and inserted mirror leg shaft support, can rotate around the rotating shaft of mirror leg (see among Fig. 9 2).Mirror leg head is connected (or mirror leg head is the last branch of foreleg body) with the foreleg of pin (or screw) (see among Fig. 9 4) and mirror leg (see among Fig. 9 5).

By the mirror leg of three sections combinations, its foreleg is a hollow tubular, and an end has rectangle small pieces (seeing Figure 10), and small pieces are an angle of perk (seeing Fig. 3) in pipe.In leg (see among Fig. 9 6) in the past an end of bottom bands of trouser legs small pieces stretch into, pine is placed in the foreleg, a section element of cone inclination angle is slightly smaller than the angle of rectangle small pieces perk under its flange end flange, the rectangle small pieces are attached on the bus of circular conical surface by self elasticity.During the head of rectangle small pieces is stuck in the semilune lock groove at leg flange place, leg can not rotate, guarantee that the position angle (seeing α among Fig. 9) of back leg (see among Fig. 9 8) tail end bending section is constant around self axis in making.During back leg inserts in the leg groove (seeing K among Fig. 9), can rotate around back leg rotating shaft (see among Fig. 9 7).

In the leg flange end move back high groove (seeing J among Fig. 7), when needs are changed the middle leg of different length or carried out some when repairing, middle leg rotated to around self axis recesses the small pieces that groove is aimed at perk on the foreleg, leg in can extracting out.

The utility model is received poststack, and two eyeglasses are in two planes that are parallel to each other, and therefore the length than general folding glasses receipts poststack greatly reduces, and is easy to carry.

The all available multiple made of each parts of the utility model.For making that glasses are in light weight, manufacturing process is simple, with adopt plastic raw materials, to utilize injection moulding or die press technology for forming to be fabricated to good.
