Abstract

The utility model relates to an adjustable glasses frame which is characterized in that the frame leg and a bridge connected two glasses frames are adjustable and a locking mechanism is arranged on the adjustable part. Because the utility model adopts the adjustable mechanism, and thereby, various glasses made by adopting the glasses frame can be suitable to the users with various hairs style and face styles conveniently. The users can obtain more convenient and the producer can reduce specification number and improve the producing standard degree during the course of producing.

Description

Adjustable glasses frame

The utility model relates to a kind of leg and the adjustable spectacle frame of picture frame crane span structure.

At present; novel; spectacle frame attractive in appearance is various in style; yet see it in length and breadth; size was too dead after spectacle frame (assembling) was shaped; and people's head different sizes; eyes; the bridge of the nose is to the distance and the face mask of ear; bridge of the nose size has nothing in common with each other; thereby people are difficult to make one's wish fulfilled when choosing the suitable spectacle frame of size in the optician's shop; perhaps both made barely satisfactory certain pair of glasses frame of having chosen; produce excessive at interval becoming flexible owing to connecting faying face (point) rubbing wear in the use; the deformation of material itself and people's ear; nose; face contact position pressurized; fricative depressions etc. cause that glasses usually wear shakiness; head tilts a little or moves; glasses just are easy to fall, and perhaps slide from the bridge of the nose, and the people who reads newspaper often need be with just hand steered; this is not only very inconvenient; and the eye retina imaging is often rocked, exacerbate eye fatigue, destruction of sight of eyes.

The purpose of this utility model is to design a kind of its leg and the adjustable spectacle frame of picture frame crane span structure, and this is novel not only to make has adaptability widely but also the standardization level of spectacle frame in producing improved having the strong user of various capitiforms and facial shape.

Detailed content of the present utility model is as follows:

Use sliding friction pair existing spectacle frame is done the improvement at position shown in (1) and (2) among Fig. 1, the detail drawing of (1) and (2) is seen Fig. 2 and Fig. 5.

Each component shown in Figure 2 is all the frame leg of spectacle frame, wherein (a) is the parts corresponding to (1) among Fig. 1, and (b), (c), (d), (e) be respectively the variant of (a), in (a), the utility model is divided into three sections with the frame leg, middle one section for two has the bolt 4 of the opposite fine thread of rotation direction, other two sections is that an end has the swivel nut (or nut) 3 and 6 with the corresponding screw thread of stage casing screw thread, the length of coming the adjusting bracket leg by swivel bolt and swivel nut.In order to guarantee the stability of frame leg length, the detail drawing that is provided with locking member 5, locking member is seen Fig. 4, square hole in the middle of it is corresponding with the square section of bolt 4, end face fluting tooth, (3) corresponding with the end face of (6) tooth of also slotting, after the frame leg length was transferred to correct position, locking member snapped in the swivel nut end face, prevented that bolt and swivel nut from rotating, guaranteeing adjusted dimensionally stable mutually.For making the variation unanimity of two frame legs, can on bolt 4, mark scale.7 is lock-screw among Fig. 2 (c).

Figure 5 shows that the crane span structure that connects two picture frames on the spectacle frame, crane span structure is made up of male-female sleeve, and 12 slide in 10 covers, and 11 is locking member.Unclamp the locking member screw, allow locking member in 10 skewed slot, slide, 12 adjust crane span structures, and can cooperate the needs of the frame pin size that has changed to the position that adapts with the various bridge of the noses and face exterior feature size so that slide.Crane span structure makes and the bridge of the nose and wide corresponding circular arc of face or linear as required, the end limit crimping of 12 elements in 10, can only slide and to get loose so that load onto locking member 11 back 10 and 12 in order to avoid fall the danger of glasses, but unload locking member, 10 and 12 is again discerptible, is convenient to the replacing respectively of spectacle frame the right and left.After size mixed up, push-tight locking member 11 was tightened the locking member screw.The change of this mechanism is convenient.

Adopt the fine tuning of this spectacle frame after changing, and can make spectacle frame and people's ear, the bridge of the nose, the wide contact position of face contact force size suitable, not only safe but also comfortable, if be equipped with external form attractive in appearance again, well spectacle frame of the pair of can yet be regarded as, if the size adjustable eyeglass circle that cooperates someone in the past to imagine again, its practicality further enlarges again.Be molten practical and attractive in appearance in one.

Adopt this change and compared originally, very simple, if the frame pin segment of curve and the frame pin straight-line segment of earrings contact position are processed with at need, can allow it be divided into two sections, adopt the whole cooperation shown in the figure three.This change is best suited for the metal frame pin, also is applicable to nonmetal pin certainly, needs much changes in manufacturing under the existing equipment condition hardly.

At present, as if contact lenses advocated by the people, but contact lenses have such as the eyeglass form, disinfect and a lot of problems such as regular replacing cleaning and inconvenience, tape holder glasses practical, attractive in appearance will be happy to buy by people, thereby its market present situation salable can not become in very over a long time.

Claims

1, a kind of glasses frame with adjustable, comprise picture frame, picture frame crane span structure and frame leg, it is characterized in that the frame leg combines by two sections or three sections, the junction of each section is with being threaded, and latch mechanism (5) is housed, and crane span structure is made up of male-female sleeve, male-female sleeve is for being slidingly connected, and male-female sleeve also is equipped with latch mechanism (11).
