Abstract

Disclosed is novel adjustable glasses. A rim (1) and glasses lens (6) can wind a transverse beam (2) to roll top and bottom, which can reduce taking and wearing trouble and avoid missing and improve work efficiency. The utility model has two kinds, single layer glasses and double layer glasses, which is suitable for various different sex, age, profession and people with different visual defect at various different situation to use.

Description

Adjustable glasses

The utility model is a kind of novel movable glasses.

Traditional various glasses, as goggles, old light microscopic (farsighted glasses), near-sighted glasses, astigmatoscope, coloured mirror and light-sensitive glasses etc., its structure mostly by frame, stride beam or eyebrow bar, mirror leg and eyeglass are formed.Mirror leg frame is fixed on frame and eyeglass at the moment on two ears during use; Time spent not, whole glasses are taken off put a place in addition.If see far away, see that inbreeding replaces frequently, getting and wear also must be frequent thereupon.Particularly when the working position changes, the problem of " looking for glasses " usually will take place, even cause loss.Selling on the market has old light and zero diopter two-part " Twopurpose mirror " on a kind of eyeglass, can reduce this trouble.But because the boundary of zero diopter and old light is in the middle part of eyeglass, sight line is only avoided this zone just can see image clearly, so people still feel inconvenience.Also have a kind of industrial Two-layer spectacle, internal layer is colourless eyeglass, and skin is a colored lens.Around the internal layer frame the netted protective cover of basin shape is arranged, striding of internal layer has sleeve pipe on the beam, entangle the outer field beam of striding, and making outer frame can serve as that axle rotates up and down to stride beam together with eyeglass.Time spent is outer to be overlapped at the moment with internal layer, before the time spent just is not turned to eyebrow to skin, more convenient.But weak point is also arranged, the first, this glasses do not have mirror leg and nose frame, are to fix on head with an elastic cord lock ring that ties up to the protective cover both sides.It is unimpeded that this elastic cord of long-time use can influence the head blood flow, and the people is felt under the weather; The second, the internal layer mirror can not rotate.If internal layer does not need the time spent yet, must take off whole glasses, still there is a problem of getting and wearing in this.And, in daily life, generally do not need to wear the glasses of protective cover.Therefore, the glasses of this structure are difficult to promote the use of in daily life.

Task of the present utility model is, in order to eliminate the problem that above-mentioned various glasses exist, design a kind of see far away, see when being used alternatingly a little less than near, light intensity, the light, all can not take off, as long as frame is turned to the novel movable glasses that get final product before the volume together with eyeglass, to alleviate the inconvenience of people when using glasses.

The scheme that solves is that a kind of centre of design is the crossbeam work backbone of nose-bridge frame, is used for connecting mirror leg, frame and bridge of the nose pad, and the bridge of the nose pad that was located at scuncheon is originally moved on on the nose-bridge frame, specially takes charge of supporting role; Weld or rivet a kind of device that matches with the crossbeam diameter in the upper edge of frame, as the collar and sleeve pipe etc., it is enclosed within on the crossbeam, the frame of band eyeglass can rotate around crossbeam.For the unlikely sweat stain by skin of the eyeglass that rolls up is polluted, consequently influence sharpness, the edge of frame has two nibs of symmetry at least, and its width is slightly larger than the maximum ga(u)ge of convex eyeglass, so just can prevent that eyeglass from contacting with skin.

When using glasses, picture frame is turned at the moment together with eyeglass, not the time spent, rolls up again, be attached on the volume.This novel movable glasses both can have been made the goggles of individual layer, old light microscopic, near-sighted glasses, astigmatoscope, coloured mirror and light-sensitive glasses etc.; Also can make the two-layer double-deck mirror that can both overturn, be that zero diopter light-sensitive glasses, skin are near-sighted glasses or farsighted glasses as internal layer, and internal layer is that colourless mirror, skin are coloured mirror etc.

The advantage of this novel movable glasses is: of many uses, easy to use, reduced trouble of getting, wearing and the chance of losing, and help raising work benefit rate.

Accompanying drawing is the synoptic diagram of novel movable glasses.

Fig. 1 is individual layer mirror embodiment, and (1) is frame; (2) be crossbeam; (3) be nose-bridge frame; (4) be bridge of the nose pad; (5) be the collar or the sleeve pipe that is positioned on frame (1) upper edge; (6) be eyeglass; (7) be nib; (8) be the beam of striding between two frames.Frame (1) can crossbeam (2) be that axle rotates up and down together with the collar or sleeve pipe (5), eyeglass (6).

Fig. 2 is double-deck mirror embodiment, and it is to increase one deck frame (9), the collar or sleeve pipe (10) again in the front of example 1 described individual layer mirror, staggers in the collar in the collar or sleeve pipe (10) and the example 1 and the position of sleeve pipe (5) on crossbeam (2).Stride beam (12) between outer two frames and connect, inside and outside two-layer frame can be distinguished together with eyeglass separately or rotate up and down simultaneously.

Claims

A kind of novel movable glasses, form by striding beam, frame, bridge of the nose pad and mirror leg, a kind of collar or sleeve pipe that matches with diameter crossbeam (2) is equipped with in the top that it is characterized in that frame (1), it can rotate around crossbeam (2), and bridge of the nose pad (4) separates with frame (1) and is installed on the nose-bridge frame (3).
