Description

Glasses frame

The present invention relates to a spectacle frame which is constructed such that a joint having a shaft bolt for folding a temple is not used, so that slack does not occur and can be stably worn forever.

The eyeglass frame is provided with temples 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 eyeglass frame. However, the front portion (21) is such that the frames (22) and (22) to which the lenses are fitted are connected by the connecting member (23), and the temples (27) are attached. And (27) are connected to the crucibles (24) and (24) brazed to both sides of the front portion (21) through the joints (26) and (26).

However, the shape of the front portion (21) is various, but the basic form of the eyeglass frame is the cymbal (24) and (24) through the joint (26) provided on both sides of the front portion (21). 26) The temples (27), (27) are foldably mounted. The glasses are for being housed in the case while being carried, and the two temples (27) and (27) are foldably mounted, but joints (26) and (26) such as hinges are used for folding.

And have shaft bolts in this joint (26), (26) (25) and (25), the temples (27) and (27) are rotated about the shaft bolts (25) and (25), and the shaft bolts (25) and (25) are loosened with the revolving. As a result, the temples (27) and (27) will swim, and the stability of the spectacle frame will be degraded. Conventionally, various measures have been taken to prevent the shaft bolts (25) and (25) used in the joints (26) and (26) from being slack.

For example, in the "anti-loose fixing bolt" of Japanese Laid-Open Patent Publication No. 2010-107029, the loosening of the joint portion is reliably performed 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 apex three points are connected by a straight line is an almost right-angled equilateral triangle, so that the right angle of the equilateral triangle is at right angle or An apex of any one of the obtuse angles is formed at the top of the return side spiral peak, the other is formed at the bottom of the valley, and the apex of the remaining acute corner portion is formed at the top of the press-in side mountain, and the aforementioned notch portion to be formed At least one or more portions are formed with a rotating portion.

The "joining structure of the eyeglass parts and the components used therefor" in the opening of 2003-185980 is a case where the eyeglass lens and the eyeglass parts are combined, and the bolts in the bolt joint portions of the both are prevented from coming loose, and the eyeglass frame parts and the eyeglass frame parts are prevented. The rotation of the spectacle lens can strongly combine the two.

Here, the shape of the outer shape is a tapered surface that forms a conical trapezoidal shape, and the shape of the cross section in the direction perpendicular to the central axis at the central portion is a conical combination of holes having non-circular shapes such as a polygonal shape and an elliptical shape. The part is inserted into a tapered hole formed in the spectacle lens. On the other hand, such as 铠 and bridge The part that is joined to the spectacle part is a specific member that uses a shape of a shape that is a non-circular shape such as a polygonal shape and an elliptical shape, and a female thread is formed at the center portion. Further, the eyeglass member is coupled to the specific member, and the member is inserted into the non-circular hole of the joining member, and the female lens and the female thread of the member are coupled to prevent the eyeglass lens and the eyeglass member from rotating. Can be combined strongly.

The requirements for glasses are to be carried on the face of the glasses. Find the stability of the position without deviation. Therefore, the shaft bolts (24) and (24) of the joints (26) and (26) are not slackened, and the spring force pressing the side of the face is directed toward the temples (27) and (27) while the glasses are loaded. Push. Conventional joints use spring hinges.

However, this spring hinge accommodates a small coil spring inside it. The coil spring is compressed by pushing the temples outward, and as a result, the spring force that pushes the temples back to the original position acts. However, the construction of this spring hinge is very complicated and the manufacturing cost becomes high. Therefore, there are various types of functions in which the leaf spring is provided on the joint side of the temple and the same function as the spring hinge. However, the joint structure also has a problem of high manufacturing cost.

[Patent Document 2] "Combination structure of eyeglass parts and parts used therefor", JP-A-2003-185980

Thus, in the conventional eyeglass frame, there is the above question question. The problem to be solved by the present invention is to provide a spectacle frame which does not have a joint provided with a shaft bolt for folding the temple, and in the case where the glasses are worn, the temple is pressed by a moderate force. The spring force on the side of the face allows stable loading.

The eyeglass frame of the present invention has a front portion and a temple, the mirror The foot can be folded, but the joint with the shaft bolt is not provided, and the joint portion is formed of a wire having excellent elasticity. Here, the joint portion can be bent and deformed when the temple is folded. Here, the joint portion may be formed continuously with the same wire as the temple, or may be formed of a wire different from the temple, and the specific material used in the joint portion is not limited.

And install when the glasses are carried in the tip end of the temple. There are ear hooks that are stuck in the ear. 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 to the locking portion provided at the joint portion. Here, the shape of the front portion is not limited, and the case has a full frame of the fitting lens, and has a half frame that restrains the upper side of the lens and a water line (horizontal line) that supports the lens, and does not have Any of the cases of the frameless front of the border is also possible. Further, the ear hook may be formed by molding the resin and the tip end portion of the temple, and the temple may be directly extended and formed of a wire.

The joint of the connecting frame of the eyeglass frame of the present invention is not used The composition of the bolts. Therefore, the bolt tightening process is not required at the time of assembly, and as a result, the manufacturing man-hour is lowered. Moreover, by not using bolts at the joints, as the looseness of the conventional bolts does not occur, the folding operation of the temples can be performed smoothly and the glasses on the face can be stabilized. In the state where the glasses are free, the two temples are in a state of being bent to some extent toward the inner side. Here, when the glasses are placed on the face, the temples are pushed outward, and a moderate pressing force acts on the face. side.

And the temples that are disposed through the joint portion on both sides of the front portion are Folding and folding toward the inside, the locking piece formed at the tip end of the temple is locked by the locking portion provided at the joint portion, and the elastic restoring force of the joint portion can be prevented even if it acts on the folded temple. The ground is kept. Further, in a state where the locking piece is detached from the locking portion, the two temples intersect in an X shape. Therefore, when the lens is carried, the reaction force (reaction force) acts by pushing the temple outward. The glasses are stably worn on the side of the face. That is, the same action and effect as the conventional spring hinge can be obtained.

Fig. 1 is a view showing an embodiment of the eyeglass frame of the present invention, wherein (a) is a plan view, (b) is a plan view, and (c) is a side view. 1 in the figure is the front part, 2 is the display temple, and 3 is the display joint. In the front portion 1, the lenses 4 and 4 are mounted to be bilaterally symmetrical, and therefore, the lenses 4 and 4 are coupled to the tip end of the coupling member 5. Further, the crucibles 6, 6 are attached to the outside of the lenses 4, 4.

The glasses shown in the figure are rimless glasses without a frame, and the lenses 4 and 4 are screwed to the both distal ends of the connecting member 5, and the crucibles 6, 6 are screwed to the outside of the same lens. Needless to say, the connecting means may be a resin-made pin instead of the above-mentioned bolt, and in the case of a resin-made pin, since only press-fitting (press-fitting) does not require a bolt tightening operation, the assembly work efficiency of the eyeglasses is improved.

However, the above-described crucible 6 connected to the outside of the lens has a curved shape, and the temple 2 is coupled to the tip end 7 of the crucible 6 through the joint portion 3. The tip end 8 of the joint portion 3 is bent, joined to the tip end 7 of the above-mentioned crucible 6 by brazing, and the temple 2 is brazed to the joint portion 3. Further, the resin-made ear hooks 9, 9 are inserted into the tip end portions of the temples 2, 2. Here, the joint portion 3 and the crucible 6 are made of a material excellent in elasticity, so when the temple 2 is folded, the connection is made. The heads 3 and 6 are greatly bent. Needless to say, the member that is bent and deformed may have a material that is excellent in elasticity only by either of the joint portion 3 or the crucible 6.

And the free-formed temples 2 and 2 are such as hinged joints. In the case of the glasses, the front end portion 1 does not extend vertically rearward, and the front end portions of the two temples 2, 2 which are inclined obliquely toward the inner side as shown in Fig. 1(a) cross each other. Therefore, when the glasses are placed on the face, the two temples 2 and 2 are pushed outward, and a moderate pressing force as a reaction force (reaction force) acts on the side surface and the back head of the face to stabilize the glasses.

Fig. 2 is a view showing a state in which the temples 2, 2 are folded. In the ear The front end of the hook 9 forms a locking piece 10, and a locking hole 11 is provided beside the locking piece 10. Therefore, as shown in Fig. 2, the temples 2, 2 are folded, and the temples 2, 2 are made by engaging the jaws 6, 6 in the locking holes 11, 11 formed at the leading ends of the ear hooks 9, 9. not open. Here, the crucible 6 is a locking portion function as a locking end of the temple. Further, when the glasses are loaded, the elastic members (spring force) of the joint portions 3, 3 and the crucibles 6, 6 are in the state of Fig. 1 (a) by being unwound from the crucibles 6, 6, and the two mirrors can be further The feet 2, 2 are pushed outwards to wear.

Figure 3 is a view showing another embodiment of the eyeglass frame of the present invention. example. In the case of the eyeglass frame, a joint having a shaft bolt is not used, and the temples 2 and 2 are coupled to both sides of the front portion 1. The temples 2 and 2 are made of a material excellent in elastic deformation, and the joint portions 12 and 12 which are formed continuously with the front side are such that the joint pieces 20 of the joint portions 12 and 12 are fitted to the front portion 1 The grooves 13 and 13 on the side. And at the apex of the joint portions 12, 12, and The decorations 14, 14 are mounted at the junction with the temples 2, 2.

The front part 1 of Fig. 3 has frames 15, 15 and two borders 15 and 15 are connected through the joint portion 16, and the nose pieces 17, 17 are attached to the center portion in pairs. Further, the locking pieces 10, 10 are provided in the apexes of the ear hooks 9, 9 which are inserted into the distal ends of the temples 2, 2, and the locking holes 11, 11 are formed beside the locking pieces 10, 10.

Here, when the temples 2, 2 are folded, the joint portions 12, 12 are greatly bent and deformed, and the joint portions 12, 12 are fitted in the locking holes 11, 11, and the locking pieces 10, 10 can be locked in the decoration 14, 14. That is, the decorations 14 and 14 function as the locking portions, and the locking pieces 10 and 10 can be locked.

Decorations 14, 14 have the effect of being decorative as glasses However, on the other hand, the decorations 14, 14 are protruded from the surfaces of the crotch portions 12, 12, and the folded frames 2, 2 are not folded by the locking pieces 10, 10 being locked to the decorations 14, 14. Will be opened to be kept. In other words, if the decorative portions 14 and 14 are not used as the locking portions, the locking pieces 10 and 10 cannot be locked to the greatly bent joint portions 12 and 12, and therefore, the temples 2 and 2 are as shown in Fig. 3(a). Open the ground.

Fig. 4 is a view showing a further embodiment of the eyeglass frame of the present invention. The front portion 1 of the eyeglass frame is the same as the eyeglass frame shown in Fig. 3, and the two frames 15 and 15 are connected by the joint portion 16, and the nose pieces 17, 17 are attached to the center of the front portion 1. unit.

Further, the cymbals 18 and 18 are attached to both sides of the front portion 1, and the temples 2 and 2 are coupled to the cymbals 18 and 18. The front end portions of the temples 2 and 2 are substantially U-shaped and the joint portions 19 and 19 are continuously formed. This joint 19 and 19 are holes through which the crucibles 18 and 18 are inserted from the inside, and the front sides of the crucibles 18 and 18 are brazed.

Further, in the joint portions 19 and 19 which are bent in a U shape, the decorative members 14 and 14 which function as the locking portions are protruded from the surface, and when the temples 2 and 2 are folded, the locking pieces 10 at the tip end of the ear hook are 10 can be locked. That is, since the joint portions 19, 19 are fitted into the locking holes 11, 11, the locking pieces 10, 10 are locked to the decorations 14, 14 and the temples 2, 2 are folded.

Here, the specific material of the joint portion which is bent and deformed in order to fold the temples 2 and 2 is not limited, but a material excellent in elastic deformation is required. Further, the temples 2 and 2 in the free state are X-shaped, and the temples 2 and 2 are pushed outward when the glasses are placed on the face. Therefore, the elastic pressing force of the joint portion urges a moderate pressing force toward the side surface and the rear head portion of the face, so that the glasses are not displaced and stabilized.
