Description

The present invention relates to a spectacle frame that supports only the inner portions of both lenses. In this specification, “inner side” and “inner side part” of a lens or the like mean “nose side” and “nose side part”, respectively, and “outer side” and “outer side part” mean “ear side” and “ear side”, respectively. It means “ear part”.

In general, eyeglass frames include a full rim type, a half rim type, and a two-point type as shown in Patent Document 1. Then, a half rim type, the apparatus having a full rim type, abuts the temple on the side of the head of the user through the armor respectively on the outside of the rim which extends to the outside along the top edge of at least the right and left lenses It is attached so as to be rotatable inward from a predetermined expanded state, and can be folded.

Among the general spectacle frames configured as described above, in the half rim type and full rim type except the two-point type, at least along the upper edge of the left and right lenses in order to fix the left and right lenses There is a metal rim. For this reason, most eyeglass frames have similar designs.
In addition, the clamping force of both temples that clamp between the ears of the user's head is adjusted so that the ears of the head do not suffer from pain even when used for a long time. The temples are adjusted according to the width to obtain the optimum elasticity, but the adjustment often goes wrong during use, making it difficult to always achieve the optimum clamping force.
JP 2003-43427 A (see FIG. 1)

In the present invention, the lens stay is positioned only on the inner side of the left and right lenses, and the lens is held only by the lens stay, and the lens stay is not positioned on the outer side of the left and right lenses. extending connecting the armor elongated, a shall attach the temple through a hinge to the armor, spectacle frames of various designs can be different from the general eyeglass frames to increase the freedom of design An object of the present invention is to provide a spectacle frame capable of manufacturing a lens having a large curve.
Furthermore, the elongated armor located outside of the upper edge portion of the lens is configured to have an elastic, by foldably connected to the temple with a hinge on the armor, to elastic deformation not only Temple, armor elongated also obtained by such elastic deformation, the inner surface of the temple to the head of the user displacement range of the temple becomes large so as to abut against a plane shape, the head An object of the present invention is to provide a spectacle frame in which a small contact force is applied to reduce the feeling of wearing and eliminate the risk of pain in the head.

The present invention has a substantially L-shape and a pair of left and right lens stays that hold the inner side of the lens, a bridge that connects the pair of lens stays, and a long armor that is connected to the lens stays. A means is provided that includes a temple that is foldably connected to the armor, and that fixes a lens stopper leg for holding the lens to both lens stays and a nose pad leg.
Then, the legs of the lens stop is a hole portion is formed first end, together with the lens is fixed by a screw shaft extending through the hole formed in the lens and the hole, the lens stop legs are bendable, the hole is to allow separable with respect to the lens stay, armor of the long is itself adopted the Tei Ru means elastic.

In the spectacle frame according to the first aspect of the present invention, only the inner portions of the left and right lenses are fixed by the lens stay, and a long armor is connected to the lens stay, and the armor is connected through a hinge. Since the temples are connected in a foldable manner, the degree of freedom in design has increased.
Further, as described in claim 2, the legs of the lens stop is hole is formed at the tip portion, the hole is not enabled separable relative to the lens stay, hole positions of example if the lens Even if the lens is displaced, by deforming the leg, the screw shaft can pass through the lens hole and the lens stopper hole, and the inner side of the lens is securely brought into contact with the lens stay. Can be fixed.
Furthermore, since the armor itself is long and elastic as described in claim 3, the armor itself elastically abuts the temple against the user's head.
Furthermore, together with the head of the user adjustable temples abutting state. Thus abuts the head of the user as a larger displaceable by cooperation with armor elongated, the head The contact width can be increased, the contact force with respect to the head can be reduced, the feeling of wearing can be reduced, and the possibility of causing pain on the user's head during use can be eliminated.

Embodiments of the present invention shown in the drawings will be described below.
FIG. 1 shows a schematic front view of a spectacle frame 1 according to the present invention, FIG. 2 shows a schematic plan view, and FIG. 3 shows a schematic view seen obliquely from above, and FIG. An armor 5 is connected to the lens stay 3, and a schematic view of a state in which the temple 6 is rotatably connected to the armor 5 via a hinge 12 is shown.

The spectacle frame 1 is a half rim type and includes a lens stay 3 and an armor 5. The lens stay 3 is in contact with an inner part of the upper edge of the pair of left and right lenses 2 and 2 and an inner part continuous with the inner part of the upper edge, and the entire lens stay 3 is L-shaped. With armor 5 is connected to the outer side of the lens stay 3, located inward (user side) of the lens 2, and extends in a curved shape to the outside than the outer portion of the lens 2.

  The pair of left and right lens stays 3, 3 are connected by bridges 4, 4 to be integrated. Further, a leg portion 16 of the nose pad 15 and a leg portion 9 of the lens stopper 8 are integrally fixed to the inner side of the inner portions of the lens stays 3 and 3 by brazing or the like.

  When the lens stay 3 configured as described above and the long armor 5 connected to the lens stay 3 are viewed from above (see FIGS. 3 and 4), the inner portions of the left and right lenses 2 and 2 are the lens stays. 3 and 3, the outer portions of the left and right lenses 2 and 2 are not fixed at all, and a long armor 5 extending from the ends of the lens stays 3 and 3 on the inner side (user) side of the portion. 5 is located, and the temples 6 and 6 are connected to the armors 5 and 5 via hinges 12 and 12 so as to be foldable. The end portions of the left and right lens stays 3 and 3 are positioned at a substantially central portion of the left and right lenses 2 and 2, and armor 5 and 5 extending outward are connected to the central portion. In the above-described embodiment, the left and right lens stays 3 and 3 and the armor 5 and 5 are connected to each other at a substantially central portion of the left and right lenses 2 and 2, but the present invention is not limited to this. Reference numeral 7 denotes a modern covering the end of the temple 6.

The left and right lenses 2, 2 holes 11 bored into the hole 10, and the lens 2 provided at the tip of the leg portion 9 of fixed lenses stop 8 on the inner side of the lens stay 3,3 Is fixed to a screw shaft 13 extending through the washer and nut 14. Therefore, the left and right lenses 2 and 2 are fixed by the screw shaft 13 and the nut 14 in a state where only the inner portions are in contact with the lens stays 3 and 3.

In this case, if the hole 11 formed in the lens 2 and the hole 10 of the lens stopper 8 do not match , the leg 9 of the lens stopper 8 is bent so that the position of the hole 10 is relative to the lens stay 3. The holes 10 of the lens stopper 8 and the holes 11 of the lens 2 are made to coincide with each other, and the screw shaft 13 is passed through and tightened with a nut 14 to securely fix the inner portions of the left and right lenses 2 and 2 to the lens stay. 3 and 3 can be held in contact.

  As described above, only the inner side of the lens 2 fixed to the lens stay 3 is held by the lens stay 3. Therefore, when viewed from the front as shown in FIG. 1, the pair of lens stays 3, 3 is fixed by a bridge 4 in a state where the substantially L-shaped lens stays 3, 3 are opened to the outside. Since the armor 5 and 5 are located on the back side (user side) of the lenses 2 and 2, when the lenses 2 and 2 are viewed, the lens stays 3 and 3 are located only on the inner side and the outer side is held. This is not done (see FIG. 1).

As shown in FIG. 2, this is a state in which only the inner portions of both lenses 2 and 2 are held, and the outer portions are not held at all, even when viewed from above. As a result, a spectacle frame having a design that has never been obtained before can be obtained, and the lenses 2 and 2 can be fixed to the lens stays 3 and 3 even if the lens 2 or 2 has a slightly poor hole opening accuracy. , 8 can be adjusted by bending the leg portion 9 .
Since the nose pads 15 and 15 that are in contact with both sides of the user's nose are also fixed to the lens stays 3 and 3 by the leg portions 16 and 16, adjustment is easy .

Furthermore, since the armor 5 itself has elasticity and the temple 6 is connected to the armor 5 via a hinge 12 so that it can be folded, not only the temple 6 but also the armor 5 can be adjusted. The armor 5 connected to the lens stay 3 can be adjusted instead of adjusting only the temple 6 around the hinge 12.
As a result, both the armor 5 and the temple 6 can be adjusted when sandwiched between the temples 6 and 6 between the upper side of the ears of the user's head, so that the state of contact with the user's head is adjusted. The possible temple 6 is made to be largely displaceable by cooperating with the armor 5 so as to contact the user's head. As a result, the abutting width of the user's head can be increased, the abutting force on the head can be reduced, the feeling of wearing can be reduced, and the possibility of causing pain in the user's head during use can be eliminated.

Therefore, unlike a general spectacle frame, a part of the temple 6 abuts on the head and a large force is applied to the head of the part to feel a strong wearing feeling. Due to the presence of the armor 5 of the scale, the temple 6 comes into surface contact, that is, comes into contact with the curved shape, and a small force is applied to each part of the head, so that the user has a strong wearing feeling even when used for a long time. I don't feel it. In addition, since the user's head is securely held, there is no possibility of shifting or dropping during use.
