Description

  The present invention relates to a spectacle frame.

  Many of the ear hooks of temples provided on conventional spectacle frames are plastically deformable materials such as titanium and copper alloys that can be bent and adjusted to maintain a state that matches the curved shape around the user's ear. (There is no patent document).

  However, the circumference of the human ear is composed of a complicated curved shape, and the curved shape varies depending on the individual, and the spectacle frame having the above-described configuration is highly skilled in the technique of bending the ear hook. There must be. For this reason, when the user wears glasses for the first time, it is necessary to have the shape of the ear hook portion adjusted by the hand of a person skilled in the folding technique in accordance with the curved shape.

  In particular, when an unexpected situation such as stepping by mistake occurs after adjustment and the shape of the ear hook is greatly deformed, it is almost impossible for a user without folding technology to readjust himself. It was. For this reason, there is a disadvantage that the user has to go to the eyeglass shop and have a person skilled in the bending technique readjust the work, which requires more care than necessary to handle the eyeglasses.

  Therefore, according to the present invention, even a user who is not skilled in the bending technique can easily adjust the ear hook portion of the temple provided on the spectacle frame according to the curved shape around the ear by himself. The problem is to provide a frame.

As a means for solving the above-mentioned problems, the present invention provides a spectacle frame having a temple having an ear hooking portion, wherein a lower edge of the ear hooking portion has an inner edge on the upper edge of the ear hooking portion. A plurality of up to 20 substantially U-shaped slits formed at an interval of 1.3 mm or more from the portion are formed at equal intervals, and the ear hooking portion is made of a heat-shrinkable tube material The modern is attached, and the modern has a non-slip step portion that is formed in plural at the lower edge of the outer surface by partially entering the plurality of slits by heat shrinkage .

  It is preferable that the modern includes an outer covering portion and an inner covering portion that cover the ear hook portion in a double manner.

  According to the present invention, since the plurality of slits are provided to partially reduce the thickness of the ear hook part, the ear hook part can be easily bent in the vertical direction. Thereby, it is not necessary to master a special technique for folding the ear hook part, and the shape of the ear hook part can be easily adjusted even if the person is not skilled in the bending technique.

In addition, even if an unexpected situation such as stepping on accidentally occurs after adjustment and the shape of the ear hook part is greatly deformed, the adjustment work of the ear hook part should be easily performed regardless of whether or not the bending technique is acquired. Therefore, the user can easily readjust the ear hook by himself / herself.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a side view of eyeglasses 1 provided with eyeglass frames 2 according to an embodiment of the present invention. FIG. 2 is a side view of the temple 6 of the eyeglass frame 2 of FIG. FIG. 3 is a partially enlarged view of the temple 6 of FIG. 4 is an enlarged sectional view taken along line IV-IV in FIG . FIG. 5 is an enlarged side view of the ear hook 8 in a bent state. FIG. 6 is a partial enlarged cross-sectional view of the ear hooking portion of FIG. The spectacles 1 include a spectacle frame 2 and a spectacle lens 3. As shown in FIG. 1, the spectacle frame 1 includes a front frame 4 that holds the spectacle lens 3, armor 5 connected to both ends of the front frame 4, and a hinge (not shown). A temple 6 rotatably attached to the armor 5;

  As shown in FIG. 2, the temple 6 includes a core metal part 7 whose base end part is branched and attached to an armor 5, and an ear hook part 8 provided continuously to the tip part of the core metal part 7. It consists of. The temple 6 is made of elastic plate-like titanium, stainless steel or the like that is not easily bent, and has a thickness t (see FIG. 4) of about 0.8 mm.

  A modern mounting portion 11 is provided in a part of the ear hook 8. As shown in FIGS. 2 and 4, recesses 9 and 10 extending along the extending direction of the temple 6 are formed at both upper and lower ends of the modern mounting portion 11. As shown in FIGS. 1, 5, and 6, the modern 12 is attached to the modern attachment portion 11. As shown in FIGS. 2 and 3, the modern mounting portion 11 is formed with a plurality of 20 or less slits 13 extending upward from the lower edge thereof at equal intervals. Each of the plurality of slits 13 has a substantially inverted U shape. In order to prevent the temple 6 from being damaged when bent in the vertical direction, the plurality of slits 13 have an arcuate edge on the back side to eliminate stress concentration and the upper edge of the modern mounting portion 11 as shown in the figure. A gap S of 1.3 mm or more is formed between the portion and the edge on the back side. Between each slit 13, there are a plurality of substantially rectangular protruding pieces 13 a.

  As shown in FIG. 4, the modern 12 includes an outer covering portion 12a and an inner covering portion 12b made of a tube material such as a heat-shrinkable polyolefin resin or silicon resin, and the modern mounting portion 11 is doubled. It is covered. The modern 12 covers the modern mounting portion 11 by applying heat to the tube material inserted into the modern mounting portion 12 to cause shrinkage. As shown in FIG. 5, the outer surface upper end edge of the outer covering portion 12a is configured to be smooth. Further, as shown in FIG. 6, the outer lower end edge portion of the outer covering portion 12 a has a plurality of anti-slip step portions 14 formed by partially entering the slits 12 of the modern mounting portion 11. Yes.

  According to the spectacle frame 2 of the present embodiment, since the plurality of slits 13 are provided in the modern mounting portion 11 to partially reduce the thickness of the ear hook portion, the ear hook portion 8 can be bent in the vertical direction. Easy. For this reason, when adjusting the ear hook 8 in accordance with the curved shape around the ear of the user who wears the glasses 1 for the first time, it is not necessary to have special skills in bending the ear hook 8, and the bending is not necessary. Even those who are not skilled in the art can easily adjust the ear hook 8 by setting the ear hook 8 as shown in FIG.

  Even when an unexpected situation such as a stepping accidentally occurs after adjustment and the shape of the ear hook 8 is greatly deformed, as described above, regardless of whether or not the bending technique is acquired, the ear hook 8 Since the adjustment work can be easily performed, the user can easily readjust the ear hook 8 by himself.

  In the eyeglass frame 2 of the present embodiment, the modern 12 covers the modern mounting portion 11 to protect the corners of the projecting pieces 13a between the slits 13 from directly contacting the user's skin. . Thereby, even if the spectacles 1 are worn for a long time, the discomfort accompanying a pain is not given to a user.

  Furthermore, in the spectacle frame 2 of the present embodiment, the anti-slip step 14 is formed at the lower edge of the outer surface of the outer covering portion 12a, so that the user has the spectacle frame 2 of the present embodiment. When 1 is worn, the said anti-slip | skid step part 14 contacts a user's ear, and the frictional force with a user's skin improves. For this reason, even if the user performs intense exercise such as sports, the ear hook 3 is not detached from the user's ear and the glasses 1 are hardly dropped on the ground or the like. It is possible to prevent the eyeglass frame 2 and the eyeglass lens 3 from being damaged.

It is a side view of the spectacles provided with the spectacles frame concerning an embodiment of the present invention. It is a side view of the temple of the spectacles frame of FIG. FIG. 3 is a partially enlarged view of the temple of FIG. 2. It is the IV-IV line expanded sectional view of FIG. It is an enlarged side view of the ear hook part in the bent state. It is a partial expanded sectional view of the ear hook part of FIG.
