Description

glasses frames

The present invention relates to an eyeglass frame, which is simple in assembly and does not occur in slack by using no bolts, and can be worn stably forever.

The eyeglass frame is such that the temples are mounted on both sides of the front portion, and the temples are foldable through a joint such as a hinge. Fig. 5 is a view showing a conventional metal spectacles frame. The front portion (11) is such that frames (15) and (15) in which lenses are fitted are connected by a connecting member (16), and temples (12), 12) is connected to the crucibles (13) and (13) brazed to both sides of the front portion (11) through the joints (17) and (17).

However, the shape of the front portion (11) is various, and the basic form of the eyeglass frame is the shackles (13) and (13) which are provided on both sides of the front portion (11) through the joints (17), (17). The temples (12), (12) are mounted so as to be foldable. In order to allow the glasses to be housed in the spectacle case during carrying, the two temples (12) and (12) are mounted so as to be foldable, and joints (17) and (17) such as hinges are used for folding.

Further, the joints (17) and (17) are provided with shaft bolts (16) and (16), and the temples (12) and (12) are rotated around the shaft bolts (16) and (16). The shaft bolts (16), (16) are loosened with the revolving. As a result, the temples (12) and (12) will swim, and the stability will be degraded when wearing glasses. Conventionally, in order to prevent the shaft bolts (16) and (16) used in the joints (17) and (17) from being slack, various efforts have been made.

For example, the "release preventing bolt" of Japanese Laid-Open Patent Publication No. 2010-107029 can reliably prevent loosening of the joint portion by the bolt of the eyeglasses. Here, the projection shape of the cross section of the bolt axis toward the notch portion of the bolt is substantially triangular, and the shape in which the three points of the apex are connected by a straight line is a substantially right-angled elliptical triangle, and the right angle of the right-angled triangle is either The apex of any one of the obtuse angles is located at the top of the return side bolt mountain, so that the other side is located at the bottom of the valley, and the apex of the remaining acute corner portion is located at the top of the push-in side mountain, and at least one of the aforementioned notch portions is formed, It has a rotating portion.

In the case of combining the eyeglass lens and the eyeglass parts, the combination of the eyeglass lens and the eyeglass parts can prevent the loosening of the bolts in the bolt joint portion of the two, and prevent the eyeglass frame. The rotation of the part and the lens of the lens, and the two are strongly combined.

Here, the shape of the outer shape is a tapered surface forming a conical trapezoidal shape, and a conical surface-shaped joint member having a polygonal or elliptical non-circular shape having a cross section in a direction perpendicular to the central axis at the center portion is provided. It is a tapered hole formed in the spectacle lens. On the other hand, as a member for being joined to a spectacle component such as a cymbal or a bridge, a specific member having a shape in which the outer shape is a non-circular shape such as a polygonal shape and an elliptical shape and a female thread is formed at the center portion is used. Moreover, by incorporating the specific member into the spectacle component, the member is inserted into the non-circular hole of the joining component, and the female screw is coupled to the female thread of the member, so that the spectacle lens and the spectacle component are not rotated. Strongly combined.

The requirement for glasses is the stability of the position when the glasses are worn on the face. Therefore, the shaft bolts (16), (16) of the above-described joints (17), (17) are not slackened, and the spring force of pressing the side of the face in the state of wearing the glasses toward the temples (12), (12) ) Push. In the prior art, the joint uses a spring hinge.

However, this spring hinge accommodates a small coil spring inside, and the coil spring is pressed by pushing the temple outward in the outward direction, and as a result, a spring force that pushes the temple back toward the original position acts. However, the construction of this spring hinge is very complicated and costly to manufacture. Therefore, the same function as the spring hinge having the leaf spring on the joint side of the temple is also various, but the joint structure also has a problem of high manufacturing cost.

[Patent Document 2] "Combination Structure of Eyeglass Parts and Parts Used Thereof", JP-A-2003-185980

As such, there is a problem as described above in the conventional eyeglass frame. The problem to be solved by the present invention is to provide a spectacle frame which does not require a joint having a shaft bolt for folding a temple, and which has a spring force for pressing the temple toward the side of the face when wearing the glasses. Can be worn steadily.

The eyeglass frame of the present invention has a front portion and a temple, and the temple is composed of a wire having excellent elasticity extending continuously from the front portion. Further, a joint having no shaft bolt is provided, and the joint is composed of a ring that rounds the wire, and the ring joint and the temple are continuously formed. The folding of the temple is performed by torsionally deforming the ring joint, and the temple can be pushed outward from the open state, and this pushing is also performed by the torsional deformation of the ring.

At the tip end of the temple, an ear hook that can be locked in the ear when wearing glasses is attached. A locking piece is formed at the tip end of the ear hook, and when the temple is folded, the locking piece formed at the tip end of the ear hook can be locked at the ring joint and cannot be opened. Here, the form of the front portion is not limited, and any of the full frame in which the lens is fitted, the half frame in which the upper side of the lens is restrained, the case where the lens is supported by the frame, and the case where there is no frame may be used. Further, the ear hook may be formed of a resin and inserted into the tip end portion of the temple, and the temple may be directly extended.

The eyeglass frame of the present invention does not use bolts. Therefore, the bolt tightening process is not required for assembly, and as a result, the number of man-hours is reduced, and the cost can be saved. Moreover, by not using bolts, the slack of the conventional bolt does not occur, the folding operation of the temples can be performed smoothly forever, and the glasses worn on the face are stabilized. In the state in which the glasses are freed, the two temples are bent to some extent toward the inner side, and the temples are pushed outward in the outward direction when the glasses are worn on the face.

And the ring formed by rounding the wire extending from the front portion serves as a joint function to bend the temple foot inwardly, and the ring joint can achieve the same effect as the spring hinge. That is, when the glasses are worn away by pushing the temples outward, the reaction force acts on the side of the face to make the glasses stably worn. On the other hand, in the case where the temple is folded, the locking piece formed at the tip end of the ear hook can be locked to the ring joint.

Figs. 1 and 2 are views showing an embodiment of the eyeglass frame of the present invention, and Fig. 1 is a plan view and Fig. 2 is a side view. The symbol 1 of the same figure is the front part, the symbol 2 is the temple part, and the symbol 3 is the ring joint. In the front portion 1, the lenses 4, 4 are mounted to be bilaterally symmetrical, and therefore, the lenses 4, 4 are held by the frame lines 8, 8, and the ends of the frame lines 8, 8 are fixed half frames 5, 5 .

However, the two halves 5 and 5 are connected to each other symmetrically by brazing by the central connecting member 6. Further, the half frames 5, 5 extend in the outward direction to form the ring joints 3, 3, and further extend from the ring joints 3, 3 toward the rear to form the temples 2, 2. That is, the half frame 5, the ring joint 3, and the temple 2 are constituted by one continuous wire. Further, resin ear hooks 7 and 7 are inserted into the tip end portions of the temples 2 and 2.

As shown in the figure, the eyeglass frame of the present invention does not use a joint having a shaft bolt, but has a ring joint 3, 3 which bends the wire in a ring shape, whereby the temple 2 is twisted by the torsion deformation of the ring joint 3, 3. 2 Bend and fold toward the inside. The temples 2 and 2 shown in Fig. 1 are positions showing the state of wearing on the face, but when the face is removed from the face, the temples 2 and 2 are slightly inside. Although the ring joint 3 of the same figure is a structure showing a ring that is wound one turn, it may be wound two times.

Fig. 3 is a view showing a state in which the glasses are removed from the face, and the temples 2 and 2 are in a state in which they are curved inwardly in an X-like manner as if they are in the figure. Therefore, when worn on the face, the temples 2, 2 are pushed outward, so that the ring joints 3, 3 can be twisted and deformed. By inserting the glasses, the two temples 2, 2 are pushed outward, and the pressing force of the temples 2, 2 toward the side of the face acts by the torsional deformation reaction force accompanying the ring joints 3, 3. Because it is the same as the temples of a conventional spring-framed eyeglass frame, the glasses worn on the face are also not swimming and stable.

Although the ring joints 3, 3 are torsionally deformed by pushing the temples 2, 2 bent inward in the X shape, since the ring joints 3, 3 are continuously extended from the half frames 5, 5 of the front portion 1, the front The portion 1 can withstand (withstand) the spring force generated by the torsional deformation of the ring joints 3, 3.

4(a) and 4(b) are a plan view and a front view showing a state in which the temples 2 and 2 are folded. The eyeglass frame of the present invention does not use a hinge joint having a shaft bolt. Therefore, the temples 2, 2 cannot be folded as in the conventional eyeglass frame, and even if folded, they can only be opened by the spring force of the ring joints 3, 3 to be in the state of Fig. 3.

Groove grooves 9, 9 are formed at the leading ends of the ear hooks 7, 7 inserted at the tip end portions of the temples, so that the ring joints 3, 3 are fitted to the notch grooves 9, 9 so that the locking pieces 10 can be locked. The locking piece 10 of the ear hook notch 9 on the right side is locked to the left side of the ring joint 3 so as to be greatly curved toward the inside, and the locking piece 10 of the left ear notch groove 9 is largely bent toward the inside. Ring connector 3 on the right. Thus, the locking pieces 10, 10 of the notch grooves 9, 9 are not opened by the two temples 2, 2 which are bent and folded inwardly by the ring joints 3, 3.

However, the eyeglass frame of the present invention is a ring joint 3, 3 formed by rounding a wire extending from the front portion, and further extends the wire from the ring joints 3, 3 to form the temples 2, 2. Here, the specific structure and form of the front portion are not limited. The front portion 1 of the eyeglass frame shown in Fig. 4 is a structure in which the lenses 4 and 4 are held by the half frames 5 and 5 and the frame lines 8 and 8, and the two halves 5 and 5 are brazed by the connecting member 6. Also. Here, the two halves 5 and 5 may be composed of one continuous wire without using the connecting member 6.

Therefore, in this case, the front portion 1 and the two-ring joints 3, 3 and the two temples 2, 2 are composed of one continuous wire. Further, the front portion 1 may have a different shape from that shown in the same figure, and a structure in which the entire frame is fitted with the lens 4 and the two full frames are brazed by a connecting member is used. Of course, the wire that extends toward the ring joint and the temple is also brazed in the full frame.

On the other hand, there is also a frameless front portion that does not have a full frame or a half frame. The frameless front portion is directly screwed between the two lenses 4, 4 by a joint member, and the flange portion extending from the ring joints 3, 3 directly on the outside of the lens is screwed.
