Description

  The present invention relates to a spectacle frame.

  Conventionally, various shapes have been proposed as an ear hook part of a spectacle frame and a modern attached to the ear hook part.

  For example, as shown in FIG. 4A, an ear hook 52 of a temple 51 used in a conventional spectacle frame is brazed to a core bar 53. Further, as shown in FIG. 4B, the cross-sectional shape of the ear hook portion 52 is also formed in a circular shape so as to match the hollow portion 55 of the modern 54 processed into a circular cross section with a drill.

  However, when the ear hook 52 is brazed to the metal core 53, there is a problem that productivity is deteriorated. Further, there is a problem that the strength between the cored bar 53 and the ear hook 52 is lowered only by brazing. Further, when the ear hook 52 and the hollow portion 55 of the modern 54 are engaged in a circular cross section, there is a problem that the modern 54 is easily twisted in the circumferential direction of the ear hook 52.

  The present invention has been made in view of the above-described conventional problems, and it is an object of the present invention to provide a spectacle frame that can improve productivity, increase strength, and modern is less likely to twist with respect to the ear hook. .

  As means for solving the above-mentioned problem, the spectacle frame according to the present invention is a spectacle frame including a core having a cored bar part and an ear hooking part extending from the cored bar part. It is provided integrally with the cored bar.

  As a specific means, it is preferable that the ear hooking portion includes a plurality of extending portions extending from the core metal portion.

  It is preferable that the spectacle frame further includes a modern covering the ear hook and attached to the ear hook, and slits through which the extending portion is inserted are provided at an upper edge and a lower edge of the modern. .

  According to the spectacle frame according to the present invention, by providing the ear hooking portion integrally with the core metal portion, the strength can be improved as compared with the case where the ear hook portion is brazed to the core metal portion.

  Moreover, since the ear hook part integrally provided in the metal core part is comprised from the some extending | stretching part extended from a metal core part, it can process by a laser processing or a press. Therefore, the step of brazing can be omitted and productivity can be improved.

  Furthermore, since the extension part of the ear hook part is inserted into the slits provided on the upper and lower edges of the modern part and the modern part is attached to the ear hook part, the modern part is prevented from being twisted around the axis of the ear hook part. be able to.

  Hereinafter, a spectacle frame according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

  The spectacles 11 include a spectacle frame 12 and a spectacle lens 13. As shown in FIG. 1A, the spectacle frame 12 includes a front frame 14 that holds spectacle lenses 13, and temples that are rotatably attached to both ends of the front frame 14 via hinges (not shown). 16.

  The temple 16 includes a core metal part 17 whose base end part is attached to the front frame 14 via a hinge (not shown), and an ear hooking part 18 extending from the distal end part 17a of the core metal part 17. The temple 16 is made of an elastic plate-like beta titanium material, SUS (stainless steel) or the like that is not easily bent, and has a thickness t1 (see FIG. 2B) of about 0.7 mm. ing.

  As shown in FIG. 1B, the ear hooking portion 18 according to the present invention includes a first extending portion 19 extending from the upper portion of the tip portion 17a of the cored bar portion 17 and a second extending portion extending from the middle portion of the tip portion 17a. 20 and a third extending portion 21 extending from the lower portion of the tip end portion 17a. The first extending portion 19 and the third extending portion 21 have substantially the same length. The second extending portion 20 is curved by 3 to 4 times longer than the first extending portion 19 and the third extending portion 21. Further, the width t2 of the second extending portion 20 is 1 mm. A modern 23 is attached so as to cover the first extending portion 19 to the third extending portion 19, 20, 21.

  The modern 23 extends in the longitudinal direction along the ear hook 18 and curves downward as shown in FIG. The modern 23 is made of resin. A first slit 24 is formed in the upper edge of the modern 23 along the longitudinal direction, and a second slit 25 is formed in the lower edge along the longitudinal direction. A hollow portion 26 is formed between the slit 24 and the slit 25.

  FIG. 2B shows a cross-sectional shape of the modern 23 attached to the ear hook 18. Each slit 24, 25, 26 has a width t3 of 1 mm and a depth t4 of 2 mm. The hollow portion 26 formed at the center of the modern 23 has a square cross section. The first extending portion 19 of the ear hook 18 is inserted into the first slit 24 of the modern 23, the second extending portion 20 is inserted into the hollow portion 26, and the third extending portion 21 is inserted into the second slit 25. It is attached to the hanging portion 18.

  According to the spectacle frame 12 of the present embodiment, the strength can be improved by providing the ear hooking portion 18 integrally with the core metal portion 17 as compared with the case where the ear hook portion 18 is brazed to the core metal portion 17. Can do.

  Since the ear hooking portion 18 provided integrally with the core metal portion 17 is composed of the three extending portions 19, 20, and 21 extending from the core metal portion 17, it can be processed by laser processing or pressing. Therefore, the step of brazing can be omitted and productivity can be improved.

  The first extending portion 19 is inserted into the first slit 24 provided at the upper edge of the modern 23, the third extending portion 21 is inserted into the second slit 25 provided at the lower edge, and the modern 23 is the ear hooking portion. 18 is attached. Therefore, it is possible to prevent the modern 23 from being twisted around the axis of the ear hook 18.

  The spectacle frame 12 of the present invention is not limited to the above embodiment, and various modifications can be made.

  As for each extending portion 19 to 21 of the ear hook portion 18, the length and shape are not particularly limited as long as the modern 23 can be attached and the strength can be ensured, and the first is as shown in FIG. The extending part 19 may be longer than the third extending part 21. Moreover, as shown to FIG. 3 (B), the 2nd extending | stretching part 20 may be linear shape.

  The modern 23 can be attached to the ear hook 18 and its shape is not particularly limited as long as it does not give the user a discomfort associated with pain even when wearing the glasses 11 for a long time. As shown in FIG. 3 (C), it may be curved more greatly than the modern 23 of the above embodiment, and as shown in FIG.
