Description

  The present invention relates to a double rim spectacle frame having a rim (first rim) for connecting right and left wisdom and a rim (second rim) for holding a lens. The present invention relates to a spectacle frame capable of increasing the degree of freedom and a method for manufacturing the same.

The spectacle frame includes a full rim type in which the entire lens is held on the rim, a half rim type in which a part of the lens is held on the rim and the other is supported by a high-tensile thread, and a rimless type without a rim for holding the lens.
Full rim type and half rim type eyeglass frames have the function of holding the lens, so the degree of design freedom is limited by the shape of the lens, and the rimless type has no premise that the eyeglass frame is designed by the rim. .
On the other hand, there is a high demand for designing various spectacle frame designs. In recent years, spectacle frames have a rim (sometimes referred to as “front frame”) at the front portion, but do not have a lens holding function. A frame has also appeared.

As described above, examples of proposals for substantially separating the lens holding function from the front frame include those disclosed in Patent Documents 1 and 2.
The rimless glasses described in Patent Document 1 have a front frame that connects the wisdom, but the lens is supported by a bridge with a fastening part and a bolt.
Further, in the lens position adjusting glasses described in Patent Document 2, the front frame does not directly hold the lens, but the lens is held by the left and right lens frames 13 provided separately.

The first rim and the second rim are arranged in a predetermined positional relationship.

The spectacle frame of the present invention can be obtained by cutting or punching from a plate material such as a metal plate and then forming each into a predetermined shape.
According to the above configuration, since the first rim and the second rim are integrally formed at the bridge portion, the first rim and the second rim can be simply bent by punching or cutting and then bending the bridge portion. The arrangement can be determined, and by forming the first rim and the second rim into predetermined shapes, a spectacle frame having a desired design can be obtained easily and inexpensively.

  Thus, in the present invention, each of the first rim and the second rim can be freely designed and designed. For example, as described in claim 2, the first rim is formed in a curved shape. And a sport-type design. In this case, the second rim has an arc shape or a linear shape having a larger curvature than the first rim in accordance with the curvature of the lens so that the lens can be held. In such a case, if the second rim is disposed rearward of the first rim, the first rim and the second rim cross each other, and an eyeglass frame with a novel design can be obtained. Can do.

It is preferable that the arrangement interval between the first rim and the second rim on the plate is variously changed according to the design of the first rim. For example, when the arrangement interval between the first rim and the second rim is increased, as described in claim 3, by bending the bridge portion a plurality of times, The second rim may be aligned.
In addition, as described above, the first rim and the second rim in the present invention can be formed by punching or cutting a metal plate or the like. The supporting leg and the connecting portion of the high-tensile yarn can be formed integrally with the first rim, the second rim, or the bridge portion.

The spectacle frame having the above-described configuration can be manufactured by the manufacturing method described in claim 5 or claim 6.
That is, the invention according to claim 5 is the method for manufacturing a spectacle frame according to any one of claims 1 to 4, wherein the first rim and the second rim are adjacent to the same plate material. And arranging the second rim integrally with the first rim at the bridge portion of the first rim, the first rim, the second rim, and the bridge portion from the plate member. The first rim and the second rim are each formed into a predetermined shape, and the bridge is bent, so that the first rim and the second rim are in a predetermined positional relationship. It is good also as a structure arrange | positioned.

  According to the spectacle frame of the present invention, the design of the first frame can be designed in accordance with the appearance of the spectacle frame and can be made independent of the second frame holding the lens. A high spectacle frame can be manufactured at low cost.
