DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge for connecting a temple to be hooked to an ear to yolo provided at both ends of a lens frame so as to be angularly displaceable.

[0002]

2. Description of the Related Art Generally, an eyeglass hinge is formed by connecting a frame hinge member and an arm hinge member to each other with pins using small screws.
The frame hinge member is fixed to the yoke, and the arm hinge member is fixed to the temple, whereby the temple is connected to the yoke so as to be angularly displaceable.

In such a typical hinge, in a typical prior art, the thickness of the hinge in the axial direction is the same as the width between both end surfaces, which are the upper surface and the lower surface when the temple glasses are mounted. Therefore, when the width between both end faces of the temple is sufficiently large, the thickness of the hinge is large, so that the strength of the hinge is large, but the width between the both end faces of the temple for reasons such as aesthetics and weight reduction. When the height of the hinge is reduced, the thickness of the hinge is reduced, and there is a problem that the strength of the hinge is reduced and the hinge is easily broken. In addition, there is a problem that productivity is poor because hinges having different thicknesses corresponding to the temples having different widths between both end surfaces must be manufactured. In addition, if the width between both end faces of the temple is smaller than the above-mentioned thickness of the hinge, the hinge protrudes outward from both end faces of the temple and the yoke, causing a problem that the appearance is deteriorated.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a temple which has sufficient strength without impairing its aesthetic appearance even if the width between both end faces of the temple is reduced, and furthermore, it is possible to increase the productivity and manufacture the temple. An object of the present invention is to provide a hinge for spectacles capable of reducing costs.

[0005]

According to the present invention, a first base fixed to a yoke has a pair of holding pieces formed in parallel with an insertion groove interposed therebetween, and each holding piece has a first shaft. A frame hinge member having holes formed therein, and a second member fixed to the temple.
An insertion piece to be inserted into the insertion groove is formed at the base, an arm hinge member having a second shaft hole formed in the insertion piece, and a first and second armature having the insertion piece fitted into the insertion groove. A shaft inserted into a shaft hole, wherein a first base of the frame hinge member includes:
A first inclined surface is formed, which extends obliquely toward each end face from the outside of both end faces of the yolo as it approaches the yolo,
The second hinge portion of the arm hinge member is provided with a second inclined surface which is inclined toward each end surface from outside of both end surfaces of the temple as approaching the temple. .

Further, the present invention is characterized in that the first and second inclined surfaces are connected in a straight line direction in a state in which the temple is in contact with the yoroi.

In this state, the shaft is inserted through the first shaft hole and the second shaft hole, and the frame hinge member and the arm hinge member are rotatably connected. The temple is connected with the hinge so as to be freely angularly displaceable by a simple hinge.

A first inclined surface is formed at the first base of the frame hinge member so as to incline toward the respective end surfaces from the outer sides of both ends of the yoke as the yoke is approached. The end fixed to the yoke can be made substantially the same width as the width between both end faces of the yoke, so that the appearance is good, and the remaining portion where the first inclined surface of the frame hinge member is formed has a sufficient amount. Since it has a width, a decrease in strength can be prevented.

A second inclined surface is formed at the second base of the arm hinge member so as to incline toward the respective end surfaces from the outer sides of both ends of the temple as approaching the temple. The fixed end portion can be made almost the same width as the width between both end surfaces of the temple, which is good in aesthetic appearance, and the remaining portion where the second inclined surface of the arm hinge member is formed has a sufficient width. , It is possible to prevent a decrease in strength.

According to the present invention, the first and the second
Since the inclined surface continues in a straight line in a state where the temple is in contact with the yolo, the appearance is further improved.

FIG. 1 is an exploded perspective view for explaining an eyeglass hinge 1 according to one embodiment of the present invention. The eyeglass hinge 1 is basically a yoke 2 that is fixed to the lens frame, a frame hinge member 3 that is fixed to the inside of the eyeglasses (upper side in FIG. 1) by being brazed at one end in the longitudinal direction of the yoke 2, The arm hinge member 5, which is brazed and fixed to the inner surface of the glasses (upper side in FIG. 1) at one longitudinal end of the temple 4, and the frame hinge member 3 and the arm hinge member 5 are rotatably connected. Screw 6 that is a shaft
And

The frame hinge member 3 has a first base 7 fixed to the yoke 2, and a pair of holding pieces 9a, 9b formed in the first base 7 in parallel with each other with an insertion groove 8 interposed therebetween. The first shaft hole 10 is formed in each of the holding pieces 9a and 9b.

The arm hinge member 5 has a second base 11 fixed to the temple 4 and an insertion piece 12 formed on the second base 11 and inserted into the insertion groove 8 of the frame hinge member 3. The insertion piece 12 has a second shaft hole 13 formed therein.

The frame hinge member 3 and the arm hinge member 5 are connected to the first and second shaft holes 10 and 10 with the insertion piece 12 of the arm hinge member 5 fitted into the insertion groove 8 of the frame hinge member 3. The screw 13 is screwed into the first and second shaft holes 10 and 13 and is rotatably assembled within a predetermined angle range around this axis. As shown in FIG. 2, the temple 4 is connected to the yoke 2 via the hinge 1 having such a configuration so that the temple 4 can be angularly displaced in the arrow 16 direction.

FIG. 3 is a sectional view taken along line III-III in FIG. With reference to FIG. 1, the first base 7 of the frame hinge member 3 has
A first inclined surface 14 is formed to extend from the outer side of both end surfaces 2a, 2b toward the respective end surfaces 2a, 2b, whereby the width W2 of the end portion 17 fixed to the yoke 2 of the frame hinge member 3 is formed. Is formed so as to be substantially equal to the width W1 between the end faces 2a and 2b of the yoke 2. The second base 11 of the arm hinge member 5 has the end faces 4a, 4b from the outer sides of the both end faces 4a, 4b of the temple 4 as approaching the temple 4.
Is formed, and a width W4 of an end portion of the arm hinge member 5 fixed to the temple 4 is set to a width W3 between the end surfaces 4a and 4b of the temple 4.
Is formed to be approximately equal to

The term "outside" means a direction perpendicular to the plane of FIG.

In FIG. 3, the frame hinge member 3 has a vertical width W5 of the remaining portion other than the first inclined surface 14 of the frame hinge member 3, and is formed through the first inclined surface 14. The end 17 fixed to the spoiler 2 has a width W2 smaller than the width W5. Moreover, the upper edge P1 of the first inclined surface 14 in FIG. 3 is closer to the temple 4 or the yoke 2 than the intersection P2 of the plane including the bottom surface 8a of the insertion groove 8 and the upper surface 18 of the frame hinge member 3 in FIG. Close. Therefore, sufficient strength can be obtained without reducing the widths L3, L4 of the pair of holding pieces 9a, 9b at the base ends connected to the first base 7, and the holding pieces 9a, 9b are fixed to the yoke 2 of the frame hinge member 3. The end portion 17 has a width W2 substantially equal to the width W1 of the yoke 2.
So it's aesthetically good. If the first inclined surface 14 is not formed, the end 17 of the frame hinge member 3, which is fixed to the yoke 2, is exposed from the yoke 2 at the exposed portions 19, 20 indicated by phantom lines, which is not aesthetically good. .

Similarly, also in the arm hinge member 5, the second inclined surface 1 which is connected in a straight line to the first inclined surface 14 of the frame hinge member 3 in a state where the temple 4 is in contact with the yoke 2.
Since 5 is formed, it has sufficient strength and good aesthetic appearance.

The first and second inclined surfaces 14 and 15 correspond to FIG.
As shown in FIG. 2, when a shaft 22 of a cutting tool such as a so-called metal saw 21 rotates in a direction of an arrow 23 around a rotation axis, a frustoconical blade portion 24 fixed to the shaft 22 rotates. The exposed portions 19 and 20 shown in FIG. 3 are formed by cutting. Since the first and second inclined surfaces 14 and 15 are formed by cutting in this manner, the width W1 between the end surfaces 2a and 2b of the
Even if the width W3 between the end surfaces 4a and 4b is smaller than the width W5 of the hinge 1, the hinges are mass-produced and the width W
Since it is sufficient to cut the hinge in accordance with the width W3 of the temple 1 and the temple 4, it is not necessary to manufacture many types of hinges according to the width of the yoro 2 and the temple, and it is possible to reduce the manufacturing cost.

FIG. 5 is a sectional view for explaining another embodiment of the present invention. This embodiment is substantially similar to the above-described embodiment, and corresponding parts are denoted by the same reference numerals. In the above embodiment, the first inclined surface 14 of the frame hinge member 3 is
Although it is provided above and below the frame hinge member 3 in FIG. 3, in this embodiment, no inclined surface is provided on the upper surface 18 side, the upper surface 18 is formed flush with the end surface 2 a of the yoke 2, and the 2, an inclined surface 26 is formed to extend from the outside of the end face 2 b of the yoke 2 toward the end face 2 b, and the temple 4 abuts on the yoke 2 in the arm hinge member 5. In this state, an inclined surface which continues in a straight line direction is formed on the inclined surface 26 of the frame hinge member 3.

Even when the inclined surface 26 is provided only on the lower surface 25 side, the upper edge P3 in FIG. A pair of clamping pieces 9
Since the widths L3 and L4 of a and 9b are not reduced,
Sufficient strength can be obtained, and the end 17 of the frame hinge member 3 fixed to the yoke 2 can be made almost the same width W2 as the width W1 of the yoke 2, which is also good in aesthetic appearance.

[0025]

As described above, according to the present invention, the frame hinge member has a pair of holding pieces formed parallel to each other with the insertion groove interposed between the first base fixed to the yoke. A first inclined surface is formed on the first base portion, the first inclined surface extending from the outside of both ends of the yoke toward each end. With such a configuration, even when the frame is thin, the frame hinge member does not change the width of each holding piece, so that sufficient strength can be obtained and the frame can be formed by forming the first inclined surface. Since there is no exposed portion of the end fixed to the hinge of the hinge member, the appearance can be improved.

The arm hinge member has an insertion piece inserted into the insertion groove, and has a second base portion fixed to the temple, a second inclined portion extending from the outside of both end surfaces of the temple toward each end surface. A surface is formed. With such a configuration, even if the temple is a thin temple, the arm hinge member has sufficient strength, and the formation of the second inclined surface eliminates the exposed portion of the end fixed to the temple of the arm hinge member, so that it is beautiful. Can be improved.

Therefore, even when the temples and the temples are thin, it is possible to realize a good-looking hinge without causing a decrease in strength.

Further, even in the case of yolo and temples having various widths, the first and second inclined surfaces may be formed by cutting or the like corresponding to the widths. Since versatility is expanded and mass production can be performed, manufacturing costs can be reduced.

According to the present invention, the first and the second
Since the inclined surfaces are connected in a straight line in a state where the temple is in contact with the yoke, the appearance is further improved.
