DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bridge portion for various kinds of glasses and sunglasses, and a nose pad portion.
In particular, the present invention relates to a bridge, a nose pad, and a mounting structure of a nose pad that can be appropriately changed according to the shape of a person using the position of eyeglasses, particularly the nose.

[0002]

2. Description of the Related Art In conventional glasses, a nose pad support portion is fixed directly to a frame covering glass, and the nose pad is changed in direction with respect to the support portion, so that the shape of the nose is different. Even so, the nose pad was along the ridgeline of the nose so that the glasses would fit on the face.

Another method is disclosed in, for example,
In Japanese Patent Publication No. 3-75724 and Japanese Utility Model Laid-Open Publication No. 4-93819, a set of pad support portions having different shapes and a nose pad attached to the tip of the support portion are prepared.
There is disclosed a configuration in which a nose pad having a different shape can be used depending on the shape of a nose of a user by being detachable from a frame or a bridge. Further, Japanese Utility Model Laid-Open No. 6-69924 discloses that a plurality of pins are provided on a lens frame, a plurality of recesses corresponding to the pins are provided on an integrally formed and deformable nose pad, and a combination position of the pins and the recesses is determined. Disclosed is a configuration in which the position of the nose pad can be adjusted.

More specifically, Japanese Patent Application Laid-Open No. 63-75724 discloses that a single leaf spring-like member is folded right and left to form concave portions facing each other at both ends of a bridge.
On the other hand, the wire used in the support portion of the pad is U-shaped, and the U-shaped portion is slid into the slit-shaped recess so as to be fixed in the recess by the spring property of the U-shaped support portion. Things. Therefore, in order to strengthen the spring property of the supporting portion, the slit of the bridge portion and the U-shaped portion of the pad supporting portion must be lengthened, and the bridge and the pad supporting portion are required to be reduced in size and weight. However, there is a problem that the restriction is imposed.

Further, Japanese Utility Model Laid-Open No. 4-93819 discloses that
A mounting hole is provided in the center of the bridge portion, and a mounting piece is provided on the front surface of the center of the support of the pad so as to fit in the mounting hole, so that the mounting piece can be hooked and mounted on the mounting hole. Therefore, in order to securely and easily attach the detachable nose pad by setting the pad, the attachment hole must be enlarged, and a certain limit is imposed on the weight reduction of the bridge itself. Since it is necessary to use a material having higher rigidity, there is a problem that a material different from a pad that requires flexibility must be used.

In Japanese Utility Model Laid-Open Publication No. Hei 6-76924,
While the position of the pad can be changed, the basic shape of the nose pad is determined by the shape of the frame at the center, and it is difficult to flexibly respond to the size and shape of the nose. Had. Further, when a thick or thin pad is used to cope with a different nose size or the like, there is a certain limit due to the influence of the design and the overall weight.

[0007] The present invention has been made in view of the problems that have arisen with such conventional nose pads that can be attached to and detached from glasses.

[0008]

Therefore, according to the present invention, the nose pad including the nose pad can be integrally formed of the same material, and the nose pad can be easily attached and detached, and the nose pad can be securely and reliably mounted. It is an object of the present invention to provide a mounting structure that not only can be fixed to spectacles, but also can reduce the weight and weight of a bridge that supports a nosepiece.

[0009]

According to the present invention, a bridge for connecting left and right spectacle lenses is provided with a nose pad having left and right pads at a nose pad portion. The nose pads have openings through which the support shafts can be inserted from both ends. The supporting shaft of the bridge can be inserted into the opening of the nose pad from both sides, respectively, and the nose pad can rotate about the supporting axis of the bridge. And, when using spectacles, locking means for restraining rotation in one direction at a predetermined position is provided on at least one of the bridge and the nose pad so that the nose pad is fixed at a predetermined use position. Have been.

[0010] The nose pad is flexible and integrally formed. Furthermore, the nose pad has a configuration in which the left and right pads are connected by a support portion. Furthermore, when the nose pad is attached to the bridge so that it can be used, one side of the bridge contacts one side of the supporting part and pushes the supporting part of the nose pad bridge in both left and right directions. Since the bridge and the nose pad have a shape related to each other so that the action of the spreading force is applied, the support by the two support shafts and the fixing at the position are further strengthened.

FIG. 2 is a perspective view of the nose pad 30 separated from the bridge 10. In particular, FIG.
3 shows a state when the camera is mounted from above.

The bridge 10 includes a central portion 11 and both end portions 1.
4 symmetrically. The front central side surface portion 12 of the central portion 11 has a curved shape with a raised center, and an end portion 14.
Is connected to the end portion 14 through a cut portion 19 cut rearward on the way to. Here, in order to explain the direction of each member, the direction in the direction of the face with glasses on the face is called "front", the direction behind the head is "rear", and the left and right sides of the face The directions of the temples are "left" and "right", and the head direction is "up".
The end portion 14 has an opening, for example, a hole 17 (FIG. 4) through which a pin-shaped hinge fixing member 5 for fixing the lens 2 can pass.
And FIG. 5). Central part 11 and end part 1
The rear surface of the lens is partially placed on the stepped portion with the lens 4 and fixed. Therefore, the end front side surface portion 15 of the end portion 14 has a surface adjusted to the curved surface of the lens such that the lens 2 and the end front side surface portion 15 are in surface contact when fixed to the lens 2 by the hinge fixing member 5. Is formed. Also, the notch 1
Reference numeral 9 denotes a shape along the shape of the edge of the lens so as to support the lens 2 from the side. Bridge 1 to lens 2
The pin-like bridge fixing member 5 for fixing the lens 2 and the bridge 10 is formed by piercing the holes at the lens 2 and the bridge 10 and then crushing or partially bending the heads at both ends thereof. And fix it. This pin-shaped hinge fixing member 5 can be made of a member such as plastic or metal.

A pair of left and right support shafts 18 are formed on the rear surface of the bridge 10 so as to project from the end 14 toward the center. The front ends of the support shafts 18 are directed substantially to the center from left and right. A central rear side surface portion 13 facing rearward of a central portion of the hinge 10 is curved symmetrically forward and left away from an axis between the two support shafts 18 as going from both left and right directions to the center direction. Forming a surface. Further, a recess 20 is formed in a lower portion of the center of the center rear side surface portion 13 so as to be partially cut away.

The nose pad 30 has a pad 32 for sandwiching the nose from the left and right, and a pad support 31 for connecting the two pads 32 symmetrically. The central portion 35 of the pad support 31 has a substantially constant width and thickness, and is curved forward. A pair of open holes or recesses 33 are provided on both sides of the pad support 31. The support shaft 18 of the bridge 10 is inserted into each of the openings 33 from both sides, and the nose pad 30 is rotatably supported on the support shaft 18.

The nose pad 30 is preferably made of the same material and integrally formed, for example, by molding. The nose pad 30 is flexible so that the pad 32 gives a soft fit to the human nose, and is made of a resilient material, such as rubber or silicon, which can sandwich the nose and support the glasses. Preferably, there is.

The nose pad 30 can be attached to the bridge 10 in a replaceable manner. Therefore, it is possible to prepare the nose pad device 30 having a different pad shape and an extension between the two pads 32 according to the shape and size of the face of the person wearing the glasses, particularly the nose.

FIGS. 4 to 7 are views showing the process of attaching the nose pad 30 to the bridge 10, and the lens part is omitted. FIG. 4 is a view of the state of FIG. 3 as viewed from the back. In particular, FIG. 6 and FIG.
A side view in which the center of the nose pad 30 is cut out shows a process of reaching a final mounted state.

As shown in FIGS. 3 and 4, the nose pad 3
The pad support 31 is brought close to the head with the head held at 0, and the tip of the support shaft 18 is brought into contact with the shoulder 37 of the pad support 31. A gentle curved surface is formed on the shoulder 37,
Since the central portion 35 of the pad supporting portion 31 is also curved, the central portion 35 can be deformed inward when the pad supporting portion 31 is further pushed forward.
The tip of 8 slides on the surface of its shoulder 37, and the tip of 18 of the support shaft is inserted into the opening 33 beyond the shoulder of the pad support 31. The nose pad 30 is returned to the original shape by the elastic force of the central portion 35 of the pad support portion 31, so that the nose pad 30 shown in FIG.
As shown by, the nose pad 30 is supported with the support shaft 18 inserted into the opening 33. As described above, in order to hold the nose pad 30 by hand to attach the nose pad 30 to the bridge 10, one of the fingers (for example, the index finger) is inserted between the left and right pads 32, and the outside of the pad 32 And two other fingers (for example, the thumb and the middle finger). When the support shaft 18 is inserted into the opening 33, the two fingers on both sides are pressed inward more strongly, so that the curved central portion 35 of the pad support 31 is formed.
Can be further deformed inward to facilitate the insertion of the support shaft 18.

While being supported by the support shaft 18, the pad 32 of the nose pad 30 is in the use position (ie, FIG. 2).
In this case, the nose pad 30 is rotated around the support shaft 18. The broken line shown in FIG. 6 is a side view showing the state shown in FIG. When the nose pad 30 is rotated while holding the pad 32, the upper part of the central part 35 of the nose pad 30 comes into contact with the lower rear part of the bridge 10.
When a stronger force is applied to rotate the central portion 35, the central portion 35 is deformed and passes over the lower rear portion of the bridge 10, and the surface of the central portion 35 of the nose pad 30 and the rear side surface of the central portion of the bridge 10 as shown in FIG. The surface of the part 13 contacts. Since the front side surface portion 36 of the central portion 35 is in surface contact with the center rear side surface portion 13 of the bridge 10, the position is not easily shifted by the frictional force, and the front side portion 36 is slightly pushed backward by the central rear side portion 13. In this state, the force becomes a force that pushes the wall around the opening 33 outward (that is, a force that pushes the curved support portion outward (in the left-right direction)), so that it becomes stronger. The nose pad 30 is fixed to the bridge 10. Therefore, the central portion 11 of the bridge 10 and the central portion 35 of the nose pad 30 are applied with a pressing force from the surface of the central rear side surface portion 13 to the surface of the front side surface portion 36 when the eyeglasses are worn at the use position. It is preferable to have such interrelated shapes. Further, as is apparent from FIG. 7, the height of the central portion 11 of the bridge 10 and the height of the central portion 35 of the support portion 31 of the nose pad 30 are substantially the same, so that the appearance is smart and the shape without discomfort is obtained. be able to. In order to remove the nose pad 30 from the spectacles, the above steps may be reversed.

When the nose pad 30 reaches the final use position on the bridge 10, the projection 34 of the nose pad 30
Fits into the recess 20 of the bridge 10. And
The upper surface 34a of the protruding portion 34 and the lower surface 20a of the concave portion 20 come into contact with each other, thereby preventing the nose pad 30 from rotating further. Therefore, the protruding portion 34 and the concave portion 20 function as locking means for stopping the nose pad 30 at that position and inhibiting further rotation. When the glasses are worn in this fixed position, a clockwise clockwise moment is applied to the pad 32 from the nose as viewed in FIG. 7, but the fixing position of the bridge and the nose pad 30 is maintained by the locking means.

In this example, locking means relating to the recess 20 provided at the lower center of the bridge 10 and the projecting portion 34 of the small piece provided below the center of the nose pad 30 fitted therein. , But is not necessarily limited to this. For example, a projecting portion may be formed above the central rear side surface portion 13 of the bridge 10, and a concave portion corresponding to the projecting portion may be formed above the central portion 35 of the nose pad 30. The rotation may be suppressed by forming only one part on one side and locking it on one surface. That is, when using glasses, the nose pad 3
It is only necessary that locking means against the rotational moment applied to zero be provided on the bridge, the nose pad, or both.

The bridge 10 according to the above embodiment of the present invention
Can be obtained by integrally molding a material such as plastic or metal, but a wire made of metal can be used in order to make it lighter and more flexible. When the wire is used, for example, the both ends of the wire are passed through the right and left glass holes, and the ends are turned back so that they face each other, so that the nose pad 30 is used as a support shaft for rotatably supporting the nose pad 30. can do. As the rotation locking means, a projection may be provided on the nose pad 30 so that one piece of the nose pad 30 is placed on the wire to prevent rotation, or the wire is sandwiched in the central portion 35 of the nose pad 30. Such a slit may be provided.

The present invention is not limited to the above embodiment,
The shape and configuration of each part can be appropriately changed and embodied without departing from the spirit of the present invention.

[0027]

As described above, according to the mounting structure of the present invention, the nosepiece can be easily attached / detached with one hand, and the supporting portions and bridges for supporting both pads can be made small. The bridge portion does not have to be troublesome when it is applied, and the weight can be reduced. In addition, since the center of the support portion that connects the bridge and the pad can be aligned, it is possible to form a shape that is smart in appearance and does not feel uncomfortable.
