Abstract

The invention provides a glasses spring hinge mechanism, wherein elastic parts are clamped with each other and are difficult to release from each other through a simple structure, so that the elastic force can be effectively transferred. Meanwhile, the metal fatigue caused by the repeated deformation of an elastic wire is also avoided so as to improve the durability thereof. The inner side surfaces of lug heads (2) arranged respectively on the left and right ends of a glasses front frame (1) are engaged with elastic wires bent into be bow-shaped and the front ends thereof are bent to be U-shaped, so as to form the arm part (5) of a reentrant front end (51). Meanwhile, the reentrant front end (51) is disposed close to washer components. The other washer (31) of a leg (3), compared with the front end of a pivot branch hole (31a), is bent to be hook-shaped as a hook part (32). When the leg (3) is expanded, the inner side surface of the hook part (32) is fixed to the inner side surface of the arm part (5) so as to be pressed. Through the bending elasticity of the arm part (5), the leg (3) is pressed toward the folding direction.

Description

The spring hinge mechanism of glasses

Technical field

The present invention relates to the improvement of glasses, in more detail, relate to a kind of by simple structure, make and suppress parts and engage with each other, be difficult to throw off, can transmit effectively elastic force, and, can prevent the metal fatigue that the repeated deformation of elastic wire causes, improve the spring hinge mechanism of the glasses of permanance.

Background technology

When wanting to take off one's glasses, have inevitably the tendency that the free end side of leg is expanded laterally by force, owing to this reason, large power is applied to the cardinal extremity part of this leg, easily causes fault, the distortion of frame.

In the past, as being used for removing the scheme of such evils, existence with hinged joint before the hinge packing ring part of hinge of frame and leg constitute can be by can flexibly advance and retreat so-called " spring hinge " (for example, referring to patent documentation 1) of motion of the volute spring that is built in the leg base end part.

But, because this spring hinge ordinary construction is complicated, and its constituent part is small, so, exist because the frequently opening and closing operations of leg, each parts depreciation that consists of, very fast this outside expand action and slow up, otherwise perhaps, wearer's sweat, sebum etc. are penetrated into Hinge mechanism inside, with corrosion such as springs, leg remains on the state that expands in the outside, is difficult to restorable situation.

And, in the situation that has produced such fault, need to change spring hinge, still, because spring hinge in the past is complex structure as mentioned above, so it is changed operation and bothers very much, needs skill, in addition, because constituent part is small and quantity is many, in any case, the high deficiency of cost is arranged also.

Embodiment

According to illustrated accompanying drawing particularly, be described as follows in further detail being used for implementing mode of the present invention.

According to Fig. 1 to Fig. 5, embodiments of the present invention are described.Among Fig. 1, symbol 1 expression be glasses front frame, this glasses front frame 1 can adopt the glasses, half frame type glasses, rimless type glasses of the such full frame type that will link to the fixing limit left and right symmetrically of pair of lenses with crossbeam of diagram etc.

In addition, what symbol 2 represented is end piece, and this end piece 2 is provided in respectively the two ends, the left and right sides of above-mentioned glasses front frame 1.

Also have in addition, symbol 3 expression be leg, this leg 3 is leading sections of being provided in above-mentioned end piece 2, can hangs over the long parts on the ear.

Have in addition, what symbol 4 represented is pivot again, and this pivot 4 has adopted the threaded parts that screw of tool in the present embodiment, but is not limited thereto, and also can use the pivot of rivet-like.

Also have in addition, symbol 5 expression be arm member, be to be the parts of arm shape with having flexible material (being β-titanium in the present embodiment) bending forming.In the present embodiment, can be the parts of the direct forming such as injection molded, casting, metallurgy by having used mould, also can be at the parts of the laggard line bend processing of shaft-like parts that temporarily have been shaped.

Then, when the hinge structure of the glasses that consist of present embodiment, at first, in the front of the end piece 2 at the two ends, the left and right sides that are provided in respectively glasses front frame 1 washer plate 21 is set.In the present embodiment, as this washer plate 21, form two packing rings (cloudy packing ring).

Then, at the other side's washer plate 31 of the base end side setting of

leg

3 and 21 combinations of above-mentioned washer plate.In the present embodiment, as this other side's washer plate 31, form a slice packing ring (positive packing ring).Then, by pivot 4 these two packing rings parts are rotated freely hinged joint.In the present embodiment, this pivot 4 is made screw component, consist of in the mode that screws with the screw thread that is located at hinge hole 21a and pivot quarter and props up the inner peripheral surface of hole 31a.

Then, at the medial surface engaging arms parts 5 of above-mentioned end piece 2.This arm member 5 forms elastic wire is bent to arc bow action section 52, and its leading section U font is turned back, and forms the leading section 51 of turning back.At this moment, this leading section 51 of turning back configures near the mode that becomes the above-mentioned two packing ring parts.

In the present embodiment, make arm member 5 be parallel a pair of elastic wire up and down, and the bridge part 51a that these leading sections 5151 of turning back are connected to each other is set.

In the present embodiment, can near the outstanding shaping arm member 5 integratedly base end part of the washer plate 21 of end piece 2, can cut down manufacturing cost.
