Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a hinge which is an eyeglass component.

[0002]

2. Description of the Related Art The edge of a spectacle supporting a lens is flexibly connected to a temple by a hinge. As shown in FIG. 15, the conventional hinge 100 has two separated tops 102 on the armor 101 side and one top 103a on the temple 103 side, and the top 103a is placed between the two tops 102. In the inserted state, the two are screwed together and connected with the screw 104.

However, with such a hinge structure, the screwing work is troublesome at the time of assembly, and it takes time and labor. Further, the degree of motion called "agagaki" for rotating the temple 103 with respect to the armor 101 depends on the degree of tightening of the screw 104, but the screwing state of the screw 104 becomes loose when the agitation operation is repeated many times. , The backlash becomes loose. Finally, the screw 104 may be removed and the temple 103 may come off the armor 101.
Further, since the tightening force of the screwing is not constant depending on the person, it is difficult to keep the backlash constant by screwing.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the conventional hinges described above, and provides a novel hinge structure that does not use screws, and at the same time, repeats the wobbling operation. It is an object of the present invention to provide a structure in which a backlash does not change even when going, and a person does not change the backlash during assembly.

[0005]

In order to achieve the above object, a hinge structure for eyeglasses according to the present invention is a hinge for connecting a temple and an armor of the eyeglass so as to be bendable with each other, the hinge being on the temple side. It comprises a top member provided and a fitting member provided on the armor side. Fitting holes are formed in the upper and lower surfaces of the top member, and the fitting member is capable of expanding in the vertical direction and non-expanding. In the state, a fitting convex portion that can be fitted into the fitting hole is formed.

The fitting protrusion may be provided on a member having a spring action capable of returning to the non-expanded state between the non-expanded states.

Further, grooves may be formed on the upper and lower surfaces of the top member so as to facilitate receiving the fitting protrusion.

The groove is formed between the direction of the temple end on the hinge side having the fitting hole when viewed from the fitting hole and the direction of the hinge opposite to the hinge when viewed from the fitting hole. It may be formed on the upper and lower surfaces between.

The groove may be deep on the outer peripheral side of the top member and may be shallower toward the fitting hole.

Further, the fitting member is formed by an attachment portion to the armor and a fitting convex portion extending vertically from the attachment portion in a substantially annular shape in the vertical direction from the tip end portions thereof in the vertical direction. An annular portion may be provided, and the annular portion may function as the spring.

The fitting member is composed of an attachment portion to the armor and two holding plates extending from above and below the attachment portion so as to face each other. The fitting protrusion may extend, and the holding plate may function as the spring.

The fitting member has an attachment portion to the armor, two holding plates facing each other from above and below the attachment portion and each having a hole, and having the spring action and both ends. A substantially C-shaped fastener having the fitting convex portion formed therein, and the fastener is fitted into the fitting hole through the holes in a state where the top member is sandwiched between the two holding plates. May be possible.

Further, a top plate for sandwiching the top member by a spring action is formed on each of the two holding plates, and the two holding plates are located at positions facing the attaching portion. In the vicinity of the cutting board, the connecting surface may be connected at a portion other than the cutting board.

Also, the various structures of the hinge can adopt the same structure as above even when the top member is provided on the armor side and the fitting member is provided on the temple side.

[0015]

If the fitting holes are formed on the upper and lower surfaces of the top member, and the fitting member is formed with fitting projections that can be expanded in the vertical direction and can be fitted into the fitting holes in the non-expanded state. , When connecting the temple and armor, align each fitting convex part with each fitting hole while keeping both fitting convex parts open, and then make both fitting convex parts non-expanded. Connection is completed simply by returning it.

Further, if the fitting convex portion is provided on the member having a spring action capable of returning to the non-expanded state between the non-expanded states, the fitting convex portions are separated from each other. Connect by simply setting the mating protrusions to the mating holes as they are in the expanded state against the spring return tendency, and then returning the two mating protrusions to the non-expanded state according to the spring return tendency. Is completed.

Further, by forming a groove on the upper and lower surfaces of the top member so as to easily receive the fitting convex portion, the thickness of the portion where the groove is formed is between the two fitting convex portions in the non-expanded state. If the distance is less than the distance, it is possible to connect the top member and the fitting member by passing both fitting convex portions through the groove portion in the unexpanded state.
On the other hand, if the thickness of the grooved portion is larger than the distance between the two fitting protrusions in the non-expanded state, the distance between the two fitting protrusions is increased from the groove while expanding the gap between the fitting protrusions against the spring return tendency. The top member and the fitting member can be connected by passing through the fitting convex portion.

Further, the groove is between the direction of the temple end on the hinge side having the fitting hole when viewed from the fitting hole and the direction of the hinge opposite to the hinge when viewed from the fitting hole. If it is formed on the upper and lower surfaces, the fitting protrusion is formed with a groove because the end of the armor is in contact with the end of the temple when the temple can be opened and the glasses can be worn. Since it cannot proceed to the side, the fitting protrusion does not come off from the fitting hole through the groove.

If the groove is deep on the outer peripheral side of the top member and becomes shallower toward the fitting hole, the space between both fitting convex portions is aligned with the groove on the outer peripheral side of the top member and the fitting hole is left as it is. When pushed in toward, the distance between both fitting convex portions naturally expands along the inclination of the groove, and the fitting convex portion can be fitted into the fitting hole as it is.

Further, the fitting member includes an attachment portion to the armor, and an annular portion formed from the attachment portion in a substantially annular shape extending vertically in two directions, and forming fitting convex portions in the vertical direction from their tip portions. If the annular portion acts as a spring, the annular portion is expanded vertically to increase the distance between both fitting convex portions, and the annular member can be inserted into the fitting hole in this state.

Further, the fitting member is composed of an attachment portion to the armor and two holding plates extending from above and below the attachment portion so as to face each other. If the holding plate acts as a spring, the holding plate can be expanded vertically to increase the distance between the two fitting protrusions, which can be inserted into the fitting hole in this state. Since the holding plate holds the top member from above and below, the fitting state of the fitting convex portion with the fitting hole is reliably maintained.

Further, the fitting member has an attachment portion to the armor, two holding plates facing each other from above and below the attachment portion and each having a hole, and having a spring action and fitted at both ends. It comprises a substantially C-shaped fastener having a convex portion, and the fastener can be fitted into the fitting hole through each hole in a state where the top member is sandwiched by the two holding plates. For example, insert the top member between the two holding plates, open the fasteners, and fit the fitting protrusions on both ends into the fitting holes through the holes in the holding plate to form the fitting member. It can be connected to the top member.

Further, top plates for sandwiching the top members by spring action are formed on the two holding plates, and the two holding plates are located at a position facing the attachment portion and in the vicinity of the top plates. If the connecting surface is connected at a portion other than the top plate, the existence of the connecting surface eliminates the tendency of the two holding plates to spread out from each other and prevents the loosening of the spring action.

In the case where the hinge is opposite to the above structure and the top member is provided on the armor side and the fitting member is provided on the temple side, the same operation as above can be obtained.

[0025]

The present invention will be described below with reference to the illustrated embodiments. 1 or 2, reference numeral 1 is a pair of spectacles to which the present invention is applied, which is a rim 3 for holding a lens.
It has a temple 5 for wearing the spectacles on the ear, an armor 7 brazed to the rim 3, and a hinge 9 for connecting the armor 7 and the temple 5. Of these, the present invention relates to the structure of hinge 9.

FIGS. 3 and 4 show a first embodiment of the hinge structure of the present invention. The hinge 9 is composed of a top member 11 provided on the temple 5 side and a fitting member 13 provided on the armor 7 side. The top member 11 is brazed to the temple 5 or integrally formed with the temple 5, or the temple 5 While the fitting member 13 is crimped to the armor 7 with two rivets 15 as shown in FIG. The two rivets 15 extend from the decoration member 17 and
Since the outer surface of the armor 7 is caulked with the rivet 15, the marks of the rivet 15 cannot be seen from the outer surface of the armor 7.

Instead of caulking with the rivet 15, the bolt 16 extending from the decorative member 17 may be tightened from the inside of the armor 7 with the nut 18 as shown in FIG. 6, or as shown in FIG. The pipe screw 20 extending from 17 may be tightened with a screw 22 from the inside of the armor 7.

The reason for caulking without brazing on the side of the armor 7 is that the fitting member 13 of the present invention requires precise dimensional accuracy. This is because an error may occur. However, as a matter of course, brazing can be applied to the fitting member 13 side if there is no fear of causing such a dimensional error.

As shown in FIG. 3, the fitting member 13 is formed by bending a single wire-shaped member, and is a portion crimped by the rivet 15, that is, the attachment portion 19.
Is formed by bending a wire-shaped member by 180 degrees to bring them into close contact with each other, and the rivet 15 is crimped between the two. The wire-shaped member is attached to the attachment portion 19
Is divided into two parts, and is bent so as to be separated from the armor 7, and after the upper and lower parts are extended in parallel, the substantially annular part 21 is formed so that the tip parts are bent so as to face each other. Incidentally, such a wire-shaped member may have a circular cross section or a rectangular cross section, but in the case of a rectangular cross section, it is preferable to cut a fitting convex portion described later into a round shape. Further, by using such a wire-shaped member, the fitting member 13 can be easily molded.

Fitting protrusions 23 are formed on the portions of the annular portion 21 where the tip ends are bent up and down, and these fitting protrusions 23 are separated from each other by a certain distance.
The fitting protrusions 23 may be in contact with each other as long as they can be separated. Further, the tips of both fitting protrusions 23 are processed into a hemispherical shape for smooth fitting at the time of fitting.

The annular portion 21 having the above-mentioned structure has a spring action in the vertical direction. Therefore, when the annular portion 21 is expanded vertically so that the distance between the fitting convex portions 23 is increased, the annular portion 21 tends to return to the original non-expanded state.

Next, the top member 11 is formed so as to project from the portion brazed to the temple 5 toward the armor 7 toward the inner surface of the temple, and has a substantially cylindrical top portion 25 at its tip. The upper and lower surfaces of the top portion 25 are parallel to each other, and the thickness in the height direction thereof is larger than the distance between the fitting convex portions 23.

A fitting hole 27 is formed in the center of the top portion 25 so as to penetrate the top portion 25. The fitting holes 27 are formed in the fitting projections 23 from above and below when the annular portion 21 is in the non-expanded state.
Can accept. In the state where both fitting convex portions 23 are fitted in the fitting holes 27, the force acting during normal use of eyeglasses unless a considerable force for separating the temple 5 and the armor 7 acts between them. Then it is not easy to come off. The fitting hole 27
Is capable of receiving the fitting protrusions 23 from above and below,
It does not have to penetrate.

Grooves 29 are formed on the upper and lower surfaces of the top portion 25 at corresponding positions. These grooves 2
9 is for making it easy to receive the fitting protrusion 23 in the fitting hole 27. That is, from the groove 29 to the fitting protrusion 23
By passing through, both fitting convex portions 23 can be easily fitted into the fitting hole 27 without widening the fitting convex portions 23 up and down.

Further, as shown in FIG. 8, the groove 29 has the top portion 2
It is also possible to make the outer peripheral side of 5 deep and taper so that it becomes shallower toward the fitting hole 27. By the way, in this way, by pushing the upper and lower fitting convex portions 23 along the taper of the groove 29 from the outside of the top portion 25, the fitting convex portion 23 can be easily fitted into the fitting hole 27, and the fitting is reversed. When removing the fitting convex portion 23 fitted in the fitting hole 27,
Since both fitting convex portions 23 have to be expanded by the thickness of the top portion 25, they are unlikely to accidentally come off.

The groove 29 is formed in the direction of the temple end 6 on the hinge 9 side having the fitting hole 27 when viewed from the fitting hole 27 and on the side opposite to the hinge 9 when viewed from the fitting hole 27. It is preferable to form it so as to be located between it and the turn direction. In this way, when the eyeglasses are worn, that is, when the armor 7 and the temple 5 are linear, the end of the armor 7 is in contact with the end of the temple 5, so that the fitting projection is The part 23 is restricted from advancing to the side where the groove 29 is formed, and the fitting convex part 23 does not come off from the groove 29.

Next, a second embodiment of the present invention will be described with reference to FIGS. 9 and 10. Also in this embodiment, the hinge 9 is composed of the top member 11 provided on the temple 5 side and the fitting member 13 provided on the armor 7 side, and is attached to the temple 5 or the armor 7 in the same manner as described above.

The structure of the top member 11 is almost the same as that of the first embodiment, but the fitting hole 27 is not penetrated, and instead, the fitting hole 2 having a concave shape as shown in FIG. 10 is used.
The only difference is that 7 is formed. In this embodiment as well, the fitting hole 27 may penetrate.

The fitting member 13 is formed by bending a plate-shaped member at 90 degrees at two positions. An attachment portion 19 is formed at the center of the bent portion, and the rivet 15 penetrates and is crimped at two holes formed therein. The upper and lower bent portions of the attachment portion 19 extend inwardly of the armor 7 in parallel with each other and form substantially circular holding plates 31 therein. These holding plates 31
Is approximately the same size as the top portion 25 of the top member 11, and both plates maintain a constant distance in the non-expanded state.

Further, a fitting convex portion 23 is formed on each of the holding plates 31 from the outer surface side of the plates to the surface side where the holding plates 31 face each other so as to be pressed into a boss shape. These fitting protrusions 23 are fitted in the fitting holes 27 of the top member 11, respectively.
It is sized to fit exactly into Then, when the top member 11 and the fitting member 13 are connected, each fitting convex portion 23 fits into the corresponding fitting hole 27, and the upper and lower holding plates 31 sandwich the upper and lower surfaces of the top portion 25 around them. are doing.

Since both holding plates 31 each have a spring action in the vertical direction, when both holding plates 31 are expanded vertically so that the distance between the fitting convex portions 23 is increased, the holding plates 31
Tend to return to their original unexpanded state. Therefore, when the top member 11 and the fitting member 13 are connected, both holding plates 3
If the fitting protrusions 23 are aligned with the fitting holes 27 in the state in which 1 is expanded vertically, the fitting protrusions 23 can be fitted into the fitting holes 27 due to the returning tendency of the holding plate 31. it can. In addition, the groove 2 of the top portion 25 described in the first embodiment.
9 is naturally applicable to this embodiment.

Next, a third embodiment of the present invention will be described with reference to FIGS. 11 and 12. Also in this embodiment, the hinge 9 is the top member 11 provided on the temple 5 side.
And a fitting member 13 provided on the armor 7 side, which are attached to the temple 5 or armor 7 in the same manner as described above.

The top member 11 of this embodiment is the same as that of the first embodiment except that the grooves 29 are not formed on the upper and lower surfaces of the top portion 25. Also, the fitting member 11
Is almost the same as the second one, but differs in the following points.

First, the two holding plates 31 are not directly formed with the fitting protrusions 23, but are provided with holes at the positions where the fitting protrusions 23 are formed in the second embodiment. 33
Are formed. When the holding plate 31 of the fitting member 13 is superposed on the top 25 of the top member 11, the position and size of the hole 33 are substantially the same as those of the fitting hole 27 as shown in FIG. Is formed in.

The fitting member 13 also includes a substantially C-shaped fastener 35 as another member. Fitting protrusions 23 are formed at both ends of the C-shaped fastener 35, and their lengths are set to be longer than the thickness of the holding plate 31. Therefore, when each fitting convex portion 23 is fitted in the hole 33, the tip of the fitting convex portion 23 is located inside the upper and lower surfaces of the top 25 in the fitting hole 27.
1 and the fitting member 13 cannot be easily separated.

Further, the fastener 35 includes the upper holding plate 31, the top portion 25 and the lower holding plate 31 when the two fitting convex portions 23 are fitted in the holes 33 and the fitting holes 27. The size is set so that there is no rattling around it. The cross-sectional shape of the fastener 35 may be circular or rectangular.

Further, since the fastener 35 has a spring action as a whole so that both fitting convex portions 23 can be expanded vertically,
When the holding plates 31 are spread vertically so that the distance between the fitting protrusions 23 increases, the holding plates 31 tend to return to their original non-spreading state. Therefore, when the top member 11 and the fitting member 13 are connected to each other, if the fitting protrusions 23 are aligned with the holes 33 and the fitting holes 27 in a state where the fitting 35 is expanded vertically, the fitting 35 can be returned as it is. Depending on the tendency, the fitting protrusion 23 can be fitted into the hole 33 and the fitting hole 27.

When the holding plate 31 is thick enough, the groove 29 having the function as described in the first embodiment can be provided on the outer surface side of each holding plate 31. In this case, unlike the first embodiment, once the fastener 35
When the fitting is fitted, there is no particular direction in which the fastener 35 is likely to come off in the bent state of the armor 7 and the temple 5, so the position of the groove is not influenced by this. Rather, the position where the groove 29 is formed is preferably a position near the armor 29 that does not interfere with the opening and closing movement of the temple 5. In this case, when the fastener 35 is fitted, it is preferable that the fastener 35 fits into the groove 29 so as not to rotate. Further, the groove 29 may have a tapered cross section as in the first embodiment.

Although the three embodiments in which the temple member 11 is provided on the temple 5 side and the fitting member 13 is provided on the armor 7 side have been described above, conversely, the fitting member 13 is provided on the temple 5 side.
Even when the armor 7 is provided and the top member 11 is provided on the armor 7 side, the hinge structure having the same form as those of the above-mentioned three embodiments can be adopted.

Here, as a fourth embodiment in which the fitting member 13 is provided on the temple 5 side and the top member 11 is provided on the armor 7 side, a modified example of the second embodiment is shown in FIGS. Will be described with reference to.

In the present embodiment, the top member 11 provided on the armor 7 side is formed so as to project from the armor 7 toward the temple 5 on the inner surface side of the armor, and has a substantially cylindrical top end. The part 25 is formed. The top and bottom surfaces of the top 25 are parallel to each other, and a hole 26 is formed at the center of the top 25.
5 is formed so as to penetrate therethrough.

On the other hand, the fitting member 1 provided on the temple 5 side
3 has a top member body 12 and an auxiliary member 14. The top body 12 has two parallel holding plates 31 on which substantially circular top plates 16a, 16b each having a substantially spring action are formed. Similar to the fitting member 13 provided on the armor side in the second embodiment, the center plates of the top plates 16a and 16b are connected to the top plate 1 from the outer surface side of the plates.
On the surface side where 6a and 16b face each other, a fitting convex portion 23 is formed by being pressed into a boss shape.

Both holding plates 31 are connected by a connecting surface 22 which vertically intersects both holding plates. This connecting surface 22
Is arranged so as to face the attaching portion 19 of the fitting member 13,
It is formed on a portion other than the cutting boards 16a and 16b. By providing the connecting surface 22 in the position facing the attaching portion 19 and near the top plates 16a and 16b having a spring action as described above, the two holding plates 31 do not tend to spread out from each other, and the top plate is removed. It is possible to prevent the loosening of the spring action of 16a and 16b. A tightening hole 24 is formed in the connection surface 22, and a substantially semicircular contact portion 28 is formed in the connection surface 22 on the tip side of the tightening hole 24.

A connection surface 22 is provided on each of the top plates 16a and 16b.
The ridges 30 are formed on the side opposite to the side on which the ridges are formed so as to bend outward. Then, a space is formed between the both convex ridges 30, and a part of the auxiliary member 14 can be received therein. In addition, in such a top member body 12, the direction with the longest length is defined as the longitudinal direction, the direction of the plane passing through both the protrusions 30 is defined as the width direction, and the direction in which the fastening holes 24 penetrate is defined as the height direction. .
This direction is also used as an expression representing the directions of the temple 5 and the auxiliary member 14 when the top member body 12 and the auxiliary member 14 are assembled together in the temple 5.

The auxiliary member 14 is a member having a convex cross section cut in a direction perpendicular to the longitudinal direction, and has a convex portion 32.
Is adapted to be received between the protruding ridges 30 of each top plate 16a, 16b. This convex portion 32
At the position corresponding to the tightening hole 24 in the top member body 12, a tightening hole 34 in which a female screw is formed is formed. The tightening hole 34 of the top member body 12 is provided in the tightening hole 34.
With 4 being aligned, a tightening screw 36 can be inserted from the tightening hole 24 side and screwed.

On both sides of the convex portion 32 in the width direction, convex strips 38 are formed along the longitudinal direction. The width and length of the ridge 38 correspond to the ridge 30 of the top member body 12,
In the state in which the convex portion 32 is received between the both protruding ridges 30 of each of the top plates 16a and 16b, the protruding ridges 3 of the top member body 12 are provided.
0 overlaps the ridge 38 of the auxiliary member 14, and these ridges 30 and 38 overlap each other.
Is configured.

The above is the fitting member 1 provided on the temple side.
It has a structure of No. 3 and can be fixed to the temple 5 as follows. First, the slot 42 is formed from the end of the temple 5 in the longitudinal direction. The cross section of this slot 42 taken in a direction perpendicular to the longitudinal direction is C
In the channel-shaped sliding surface 44, a receiving groove 54 having a width larger than the diameter of the tightening screw 36 is formed. The receiving groove 54 is for preventing the surrounding buildup that occurs when the tip of the tightening screw 36 strongly abuts the sliding surface 44 of the slot 42, and prevents the surrounding buildup from rising above the sliding surface 44. As a result, when the top member 11 is slid and removed from the temple 5, smooth sliding can be maintained.

The top member 11 can be slidably fitted into the slot 42 from the end side in a state where the convex strips 30 and 38 of the top member body 12 and the auxiliary member 14 are overlapped with each other. The fitting is completed when the abutting portion 28 of the top member body 12 abuts and stops, and at this time, the fastening hole 24 and the fastening hole 3
4 and the receiving groove 54 are aligned. Then, a tightening screw 36 is inserted into the tightening hole 24 and the tightening hole 34, screwed until the tip of the tightening screw 36 comes into contact with the receiving groove 54, and then the screw is further tightened.

As a result, as shown in FIG. 14, after the tip of the tightening screw 36 comes into contact with the receiving groove 54, the auxiliary member 14
Shifts to the right side of FIG. As a result, the ridge 30 of the top member body 12 strongly abuts against the slot 42, and the top member body 12 and the auxiliary member 14 are fixed to the temple 5 by a frictional force.

As described above, the structure in which the connecting surface 22 is formed between both the holding plates 31 to prevent the spring force from decreasing is the same as the second embodiment shown in FIG. 9 and the third embodiment shown in FIG. The same can be applied to each fitting member 13 of the embodiment.

[0061]

As described above, since the hinge of the present invention does not use screws, the work of attaching the temple to the armor can be easily performed. Moreover, the screws will not loosen,
No matter how many times he or she moves, the condition of the backlash does not change. Further, in the case of a screw, the degree of backlash differs depending on the tightening condition of the screw, but in the present invention, the fitting convex portion is always fitted into the fitting hole with a constant force by the spring action. It does not fluctuate.
