Below with reference to Fig. 3～Fig. 7 the effect of the glasses 1 of embodiments of the present invention is described.

As shown in Figure 3 and Figure 4, be inserted into the patchhole 8a of arm 8, the front end of the pin 8c (Fig. 2) in slot 9b that is located at bar 9 cardinal extremities and the pin-and-hole 8b that is entrenched in arm 8 engaged, thereby bar 9 is linked on the arm 8 by cardinal extremity with bar 9.

At this moment, volute spring 10 is pre-assembled rolling around bar 9, and the one end does not deviate from it from inboard head 9a butt with bar 9 to limit this volute spring 10 from bar 9.In addition, the other end butt of the slide block of tubular 11 and volute spring 10, and along bar 9 in the enterprising line slip of the length direction of bar 9.

In addition, as shown in Figure 5,, arm 8 is inserted among the accepting hole 7a of the sleeve pipe 7 of being located at mirror leg 3 base portions while sliding, but when inserting, the material elastic force of the 11a of umbrella portion of the slide block 11 antagonism umbrella 11a of portion is out of shape to the inside, is deformed into the posture of keeping out of the way of the accepting hole 7a that can insert sleeve pipe 7.And at this moment, the crushed element that is deformed into the slide block of keeping out of the way posture 11 of the accepting hole 7a that can insert sleeve pipe 7 to the inside is housed in keeping out of the way in the groove 9c of bar 9.

Then, arm 8 is inserted in the accepting hole 7a of sleeve pipe 7, the abutting part 2c of mirror leg seat 2b is at the foreign side of connection shaft 5b and the base end part 3a butt of mirror leg 3, then the 11a of umbrella portion of slide block 11 turns back to outstanding posture by the material elastic force of the 11a of umbrella portion, engages and limits slide block 11 and break away from from sleeve pipe 7 with anticreep groove 12a on being located at accepting hole 7a inwall.

Like this, by jut 12b and the anticreep groove 12a that are located between sleeve pipe 7 and the slide block 11, come limiting boot 7 to break away from from arm 8 as the slide block 11 of escapement 12.

Have again, so be in and eyeglass 2 roughly under the state of the abutting part 2c butt of the upwardly extending base end part 3a that opens posture, mirror leg 3 in the side of quadrature and mirror leg seat 2b at mirror leg 3, volute spring 10 is adjusted to: this volute spring 10 is compressed and the base end part 3a of mirror leg 3 is pressed to the abutting part 2c of mirror leg seat 2b by slide block 11 and sleeve pipe 7.Under this state, glasses 1 are worn along the temporal mode of human body head with mirror leg 3.

Then, as shown in Figure 6, becoming contact point with the abutting part 2c of the base end part 3a of mirror leg 3 and mirror leg seat 2b at mirror leg 3 is center and from opening posture further under the state that extends out posture that foreign side rotates, sleeve pipe 7 is with respect to the preceding extreme direction displacement of bar 9 to bar 9, and by slide block 11 compression helical springs 10.Therefore, by the elastic force of this volute spring 10 that has been compressed and sleeve pipe 7 is worked with respect to the power of the mirror leg side hinge 5c of portion displacement, mirror leg 3 is applied make it get back to the power of opening posture from extending out posture.

In addition, as shown in Figure 7, at mirror leg 3 by under the state of the folding posture that eyeglass 2 is folded up, the restrictions 5d of the mirror leg side hinge 5c of portion and the end 7b butt of sleeve pipe 7, limiting boot 7 is to the mirror leg side hinge 5c of portion displacement.

At this moment, though volute spring 10 is compressed, because the end 7b of sleeve pipe 7 is pushed to the restrictions 5d of the mirror leg side hinge 5c of portion by slide block 11 and sleeve pipe 7, therefore, acting force is inoperative between mirror leg 3 and mirror leg seat 2b, and mirror leg 3 is successfully rotated with respect to mirror leg seat 2b.

As mentioned above, glasses 1 according to the embodiment of the present invention, by connection shaft 5b eyeglass side hinge 5a of portion and the mirror leg side hinge 5c of portion are linked up rotationally, can to make mirror leg 3 become contact point with the abutting part 2c of the base end part 3a of mirror leg 3 and mirror leg seat 2b be the center further extends out posture to what foreign side rotated from opening posture.At this moment, become under this state that extends out posture at mirror leg 3, sleeve pipe 7 slides to the preceding extreme direction of bar 9, and by slide block 11 compression helical springs 10, therefore, by the elastic force of this volute spring 10 that has been compressed and sleeve pipe 7 is worked with respect to the power of the mirror leg side hinge 5c of portion displacement, can apply mirror leg 3 and make it get back to the power of opening posture from extending out posture.

In addition, because mirror leg 3 can become the flexible posture that extends out, therefore, even the mirror leg 3 of opening posture is applied toward the outer side bigger power, can not produce bigger concentrated stress at the base end part 3a of mirror leg 3, the breakage of the mirror leg 3 that can prevent reliably because metal fatigue etc. causes yet.

In addition, even at the width of head during greater than the width of the mirror leg 3 of opening posture, because mirror leg 3 becomes the state that extends out posture, can utilize the elastic force of volute spring 10 that glasses 1 are worn on the head, therefore can flexibly adapt to the different face width of different people, the result makes glasses 1 be rich in versatility.In addition, utilize the elastic force of volute spring 10 can obtain appropriateness soft wear sense, wear very comfortable.

And, according to the present invention, the force application mechanism of this volute spring 10 is incorporated in the accepting hole 7a, not only be not exposed to the outside, and be provided with the escapement 12 that limiting boot 7 breaks away from from arm 8, therefore, as long as force application mechanism is inserted in the sleeve pipe 7, just can easily assemble to become the comfortable glasses 1 that this elasticity extends out posture.

In addition, owing to be under the state of opening posture at mirror leg 3, the base end part 3a of mirror leg 3 is pushed to the abutting part 2c of mirror leg seat 2b, therefore, opens under the state of posture at this, and mirror leg 3 can not rock with respect to mirror leg seat 2b, can stably keep and open posture.

Have again, at least at mirror leg 3 be under the state of the folding posture that eyeglass 2 is folded up, the restrictions 5d butt of the end 7b of sleeve pipe 7 and the mirror leg side hinge 5c of portion, the abutting part 2c butt of the base end part 3a of mirror leg 3 and mirror leg seat 2b when becoming open mode, only otherwise become the end 7b of sleeve pipe 7 and the state that restrictions 5d separates, just therefore the acting force that 3 effects are not rotated mirror leg 3 to the mirror leg can make mirror leg 3 successfully rotate in the clear.

In addition, owing to adopt and to make the anticreep groove 12a that is located on the accepting hole 7a inwall and jut 12b on being located at slide block 11 engage so simple structure just can to limit slide block 11 reliably from sleeve pipe 7 disengagings, therefore, can realize escapement 12 cheap for manufacturing cost and that reliability is high.

Especially in slide block 11, since hole enlargement become the 11a of umbrella portion of umbrella be constituted as material elastic force at the 11a of this umbrella portion antagonism umbrella 11a of portion be deformed into to the inside the accepting hole 7a that can insert sleeve pipe 7 keep out of the way posture and with outstanding posture that anticreep groove 12a engages between deform, therefore, keep out of the way posture by slide block 11 being deformed forming, can easily be inserted into slide block 11 in the accepting hole 7a of sleeve pipe 7.In addition, because making the anticreep groove 12a that is located at accepting hole 7a inwall engage so simple structure with the 11a of umbrella portion that becomes outstanding posture, employing just can prevent reliably that limited slip block 11 breaks away from from sleeve pipe 7, therefore, can realize the escapement 12 that manufacturing cost is cheaper and reliability is high.

In addition, because what bar 9 had the crushed element that is used to accommodate the slide block of keeping out of the way posture 11 that is deformed into the accepting hole 7a that can insert sleeve pipe 7 to the inside keeps out of the way groove 9c, therefore, slide block 11 is deformed become and keep out of the way posture, can more easily be inserted into slide block 11 in the accepting hole 7a of sleeve pipe 7.

In addition, owing to be inserted at the cardinal extremity of bar 9 under the state of patchhole 8a of arm 8, employing makes the front end of the pin 8c among slot 9b that is located on bar 9 cardinal extremities and the pin-and-hole 8b that is entrenched in arm 8 engage so simple structure and just can be attached to reliably on the arm 8 by barre 9, therefore, can realize escapement 12 cheap for manufacturing cost and that reliability is high.

Have again, because mirror leg 3 forms by marmem, so, the such problem of plastic yield also can not occur taking place even enlarge the spacing of each mirror leg 3 significantly.

In addition, when adorning oneself with glasses 1, by the recuperability of the elastic deformation of the mirror leg 3 that is made of marmem and this two mechanism of force application mechanism that is located on the hinge glasses 1 are worn on the head, it is soft and comfortable therefore wearing sense, and can obtain reliable anti-drop function.
