Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a supporting leg for an eyeglass frame and a nose pad.

[0002]

[Prior art]

 A nose pad is attached to the spectacle frame, and the nose pad supports the front frame portion. As is well known, the shape of the nose pad is different between the metal frame and the resin frame, and is made integrally with a part of the rim in which the lens is fitted in the resin frame. In the case of a metal frame, the legs are extended from the rim and attached to the tip.

The legs are generally made of metal, and when the nose pad attached to the tip hits the nose, the direction of the nose pad itself can be freely changed to conform to the nose to support the front frame. However, since the leg is not bent, the contact of the nose pad directly acts, which is one of the causes of promoting fatigue when wearing glasses. Of course, there are also cases where a thin spring wire is used or a coil spring is used as the leg because it is made of metal and gives the leg flexibility. However, since the leg made of spring material has a large restoring force, it cannot be finely adjusted by bending and deforming.

Further, the position of the nose pad can be adjusted by bending the metal legs, but since the legs are brazed to the front frame, the place where the row is attached is bent at the time of bending. It may come off. In addition, the amount of adjustment is limited because the method of adjusting the metal legs is limited to bending.

[0005]

[Problems to be solved by the present invention]

 As described above, the conventional metal legs have the above problems. The problems to be solved by the present invention are these problems. The amount of adjustment is large and the adjustment is easy, and the nose pad of the spectacles frame works softly on the nose to reduce fatigue even when wearing glasses. Providing support legs.

[0006]

[Means for Solving the Problems]

 The nose pad support legs according to the present invention are made of resin that is highly elastically deformable, and for example, polyphenyl sulfone is suitable. The shape of the support leg is composed of an attachment portion for attaching to the front frame, a curved portion having a substantially U shape, and a fastening portion for fastening the nose pad. The attachment part has a fitting part and can be pinned or screwed, and a part of the attachment part can be cut to have an adjustable structure.

One of the fastening portions is for fastening the nose pad, and therefore the fastening portion has a structure in which the direction of the nose pad can be changed. Of course, the specific shape is not limited, and for example, a spherical fastening portion that fits into a spherical bearing formed on the nose pad can be used. Therefore, the fastening portion is determined in relation to the receiver formed on the nose pad. As described above, the support leg of the present invention is attached to the front frame, but the attachment location is not limited, and the material may be metal or resin. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 is an embodiment showing a nose pad according to the present invention. The support leg is made of resin and is an integrally molded part having an attachment portion 1, a curved portion 2, and a fastening portion 3. Polyphenyl sulfone or the like, which is excellent in elastic deformation, is used as the resin material, and it can be flexed as a supporting leg, and the nose pad can act on the nose softly. The attachment portion 1 of the support leg is bent from the curved portion 2 and extends upward to form three through holes 4, 4, ... And the attachment portion 3 is a sphere. The support leg is attached to the front frame via the attachment portion 1, and the nose pad is fixed to the attachment portion 3.

FIG. 2 shows a specific example of how the support legs are attached. Reference numeral 5 in the figure represents a connecting member, which connects the lenses symmetrically, and is an integrally molded component made of resin having the same properties as the supporting legs. A supporting portion 6 is formed on the back side of the connecting member 5 so as to project, and the supporting portion 6 has an attaching hole into which the attaching portion 1 can be fitted in the vertical direction without rattling. Crossed pin holes are provided from the side. Therefore, as shown in the figure, the attachment portion 1 of the support leg is fitted into the attachment hole, and the two pins 8 and 8 penetrate the through holes 4 and 4 and separate from the attachment hole of the support portion 6. I'm trying not to.

Further, a joint 9 projects outward from the connecting member 5. The connecting member 5 is a pair of glasses which has no rim and is used for directly connecting and fixing the left and right lenses with screws, and the joint 9 contacts the back surface of the lens to fix the lens. Therefore, a screw hole 10 penetrates the joint 9. Of course, the present invention is characterized by the above-mentioned supporting legs, and the structure of the connecting member 5 is not limited. Therefore, it is also possible to form the support portion 6 on the frame integrally formed with the rim for fitting the lens and attach the support leg to the support portion 6. Not only when the support portion 6 and the joint 9 are integrally formed with the connecting member 5, but when the support portion 6 and the joint 9 are made of metal, the support portion 6 and the joint 9 which are processed as separate parts can be brazed.

FIG. 3 shows a specific example of the nose pad 11. The nose pad 11 is formed by integrally molding a pad portion 12 and a receiving portion 13. The receiving portion 13 forms a spherical bearing, and the fastening portion 3 of the supporting leg is fitted and connected. . Of course, when the shape of the fastening portion 3 is different, the shape of the receiving portion 13 of the nose pad 11 is also different accordingly. FIG. 4 shows another specific example of the fastening portion 3, which is a U-shaped fastening portion, and both side pieces 14 and 14 of which have bendable pins 15 and 15 protruding inward. A conventional nose pad mounting metal fitting is fitted between the both side pieces 14, 14 in the fastening portion 3, and the pins 15, 15 are fitted in the screw holes of the metal fitting.

FIG. 5 shows another embodiment of the supporting leg of the present invention. The basic form is the same as the support leg shown in FIG. 1, but the attachment part 1 is different, and the tabs 16, 16 ... Are formed without having the through holes 4, 4 ,. Has been. The supporting leg is fitted into a hole formed in the supporting portion 6 of the connecting member 5, and at this time, a part of the tip of the attaching portion 1 is cut to adjust the length, and the position of the fixing portion 3 (height ), And then the position of the nose pad is adjusted. This is also the case with the support legs shown in FIG.

FIG. 6 is slightly different from the above-mentioned support leg form, and the attachment portion 1 is formed on the extension of the curved portion 2. A hole 17 is formed in the attachment portion 1, and pin holes 18, 18 are perpendicular to the hole 17. Therefore, a support piece that fits into the hole 17 is provided on the frame side, and a pin is fitted into and fixed to the pin hole 18, 18. The pins may be straight pins or split pins may be encountered. As described above, the nose pad support legs according to the present invention are integrally molded of a resin having excellent elastic deformation, and have an attachment portion, a curved portion, and a fastening portion. The following effects can be obtained.

[0014]

[Effect of device]

 Since the nose pad support legs of the present invention are made of resin and have a curved portion, they can be elastically deformed and flexed so that the nose pad fits to the nose. Therefore, it is comfortable against the skin and wears little eyeglasses for a long time. Also, since it is made of resin, it can be locally bent and deformed, and the position of the nose pad can be adjusted to fit the nose. On the other hand, by locally bending and cutting a part of the tip of the attachment part, the position of the fastening part, that is, the position of the nose pad can be optimized. Furthermore, if the support legs are formed as independent parts, it is possible to select and use the support legs that are suitable for the eyeglass frame, and since the parts can be shared, it is convenient to manufacture the eyeglass frame.
