Description

  The present invention relates to a flip-up type spectacle frame equipped with another flip-up frame that can be flipped up on glasses, and a flip-up device.

  Conventionally, the flip-up glasses generally referred to are glasses configured such that another flip-up frame attached to the front of the front portion opens and closes up and down. This type of glasses has been well known, and for example, a type in which sunglasses are attached to myopia glasses and flipped up, or a pair of reading glasses is flipped up. That is, the front frame is a glasses frame having a double structure, and the front side (front side) frame can be flipped up.

  By the way, the flip-up type spectacle frame has a flip-up frame attached thereto, but the flip-up frame is flipped up obliquely upward with respect to the front portion. The flip-up frame is attached to the front part via a joint and has a structure that cannot be lowered and closed. However, when the body is moved violently, it is often closed by an impact.

  By the way, what is shown in FIG. 7 is known as what is employ | adopted as the flip-up apparatus of the conventional flip-up type spectacles frame. As can be seen from the figure, the spectacles have a flip-up frame (A) and a front part (B) of the spectacles with a temple attached, and a concave joint (C) and a convex joint (N ) Are attached and connected via a pin (e).

  Then, the convex joint part (d) is fitted into the concave joint part (c), and a leaf spring (not shown) fixed to the open bottom surface (f) of the concave joint part (c) is the butted surface of the convex joint part (d) Is in contact with the spring force biased. Therefore, when the flip-up frame (A) is flipped up, the leaf spring is deformed and pushed toward the bottom surface, and is restored to its original shape when it contacts the upper surface of the convex joint (D). Of course, since a predetermined spring force is applied even when it comes into contact with the upper surface, the flip-up frame (a) does not close alone, but keeps the state of being flipped up obliquely upward.

  However, the flip-up device is composed of a small convex joint part (d) and a concave joint part (c), and has a structure in which a leaf spring is attached thereto. Since it cannot be absorbed, the flip-up frame (A) descends and closes. On the other hand, when the flip-up frame (a) has a large curved shape, that is, wearing sunglasses that are curved with respect to the flat front part and extend to the side of the face as the flip-up frame (a) is the same. This is not possible with the conventional flip-up device as shown in the figure.

  As described above, the conventional flip-up type spectacle frame has the above-described problems. The problem to be solved by the present invention is this problem, and provides a flip-up type spectacle frame and a flip-up device that enable stable flip-up and that are equipped with sunglasses that are greatly curved as a flip-up frame.

  The flip-up spectacle frame according to the present invention has a combined structure of a largely curved flip-up frame and a front portion of general correction glasses. The front part of the glasses is attached inside the curved frame, and a flip-up device is attached to the center of the curved frame, and the flip-up frame is fixed to the flip-up device. Moreover, the vine is attached to the both ends of a curved frame so that folding is possible. Here, the shape of the curved frame and the shape of the raised frame to be raised are not limited.

  The flip-up device is configured so that the flip-up frame can be flipped up, and the stability of the flipped-up frame is maintained. The flip-up device includes a box and a slider. The slider is provided with a hole serving as a spring accommodating space, and a coil spring is accommodated in the hole. The slider containing the coil spring is fitted in a slide groove formed in the box so as to be slidable, and the tip of the slider protrudes from the box.

  The box is fixed to the front side, and the metal fitting attached to the flip-up frame is connected to the tip of the slider via a shaft pin. Therefore, the flip-up frame is swung up around the shaft pin, and the contact surface formed on the metal fitting is in contact with and supported by the upper end surface of the box. In this case, the slider is pulled by the spring force of the coil spring, and the metal fitting is pressed against the upper end surface of the box to be stabilized.

  The flip-up spectacle frame of the present invention is flipped up by a flip-up device having a coil spring having a certain length. The coil spring of the flip-up device stably supports the flipped-up frame, and even if the body is moved violently, the coil spring absorbs the shock at that time and does not close alone. The flip-up frame can be flipped up by expanding and contracting the coil spring, but the operation is smooth.

  Further, the flip-up type spectacle frame of the present invention has a structure in which the front part of the correction glasses is attached to the inside of the curved frame, and the sunglasses are attached to the curved frame so as to be flipped up. That is, it can be constituted by a combination of a front portion of general correction glasses and a curved frame.

  FIG. 1 shows an embodiment of a flip-up type spectacle frame according to the present invention. In the figure, reference numeral 1 denotes a front portion, 2 denotes a curved frame, 3 denotes sunglasses, and the front portion 1 is a front portion of conventional correction glasses, and a lens is fitted on the rim. The temples 5 and 5 are attached to both sides of the curved frame 2 via hinges 4 and 4 so that they can be folded. A flip-up device 6 is attached to the center of the curved frame 2, and the sunglasses 3 is attached to the flip-up device 6 and flipped up. That is, the sunglasses are configured as a flip-up frame.

  FIG. 2 shows the front part 1, which has both rims 7, 7 connected by a connecting part 8, and nose pads 9, 9 attached to the center part. Further, rim locks 22 and 22 which are screwed are provided on the outside of the rims 7 and 7. By loosening the screws, the peripheral length of the rims 7 and 7 can be enlarged, and the lens can be attached and detached. This structure is the same as the front part of conventional general glasses.

  FIG. 3 shows a case where the sunglasses 3 are attached to the curved frame 2, and the curved frame 2 has both rim portions 10, 10 and a connecting portion 11, and a lens is fitted on the rim portions 10, 10. The sunglasses 3 are attached to the front of the curved frame 2. Although the manufacturing method of the curved frame 2 is not limited, it is manufactured by cutting a metal plate excellent in elasticity, and brazing pieces 12 and 12 are provided on a part of the rim portions 10 and 10. The front portion 1 is attached to the brazing pieces 12 and 12 by brazing.

  A flip-up device 6 is attached to a connecting portion 11 provided between the rim portions 10, 10, and the sunglasses 3 is attached to the curved frame 2 through the flip-up device 6. Therefore, the sunglasses 3 can be flipped upward. When the sunglasses 3 are closed as shown in FIG. 1, they can be seen through the correcting lenses 13 and 13 fitted on the rims 7 and 7 of the front portion 1 and the sunglasses 3, and the sunglasses 3 is raised and opened. In this case, the image can be seen only with the correction lenses 13 and 13 of the front portion 1.

  This flip-up type spectacle frame is provided with sunglasses 3 that are largely curved on a curved surface, and is attached to the curved frame 2 for that purpose. That is, the sunglasses 3 that are largely curved cannot be directly attached to the substantially planar front portion 1. In order to maintain the shape of the curved frame 2, the front portion 1 is attached by brazing, and the curved frame 2 is configured as a frame having a combined structure of the curved frame 2 and the front portion 1, and its strength is extremely high. .

  In the present invention, the sunglasses 3 can be flipped up smoothly, and the flipped-up sunglasses 3 is provided with a flip-up device so that it does not fall down and close by itself even when exercising. FIG. 4 shows a flip-up device 6 according to the present invention. The flip-up device 6 comprises a box 14 and a slider 15, and the slider 15 is slidably accommodated in the box with a coil spring 16 attached thereto.

  (a) shows the case where the coil spring 16 is extended and the tip 17 of the slider 15 is retracted, and (b) shows the case where the coil spring 16 is compressed and the tip 17 of the slider 15 protrudes. FIG. 5 shows the box 14 and the slider 15 independently. The box 14 is provided with a slide groove 18 over its entire length, and a coil spring accommodating groove 19 is formed at a predetermined length from one end. Accordingly, when the slider 15 protrudes, the coil spring 16 is compressed and a spring force for pulling the slider 15 is urged. A rectangular hole 21 is provided through the slider 15, and the coil spring 16 is accommodated in the rectangular hole 21.

  The box 14 has a substantially U-shaped cross section, and a coil spring accommodating groove 19 is formed so as to overlap with a slide groove 18 provided over the entire length. However, the coil spring accommodating groove 19 is not provided over the entire length but is provided over a predetermined length from one end, and the groove bottom 20 serves as a stopper for the coil spring 16. That is, the slider 15 is fitted in the slide groove 18, the coil spring 16 is accommodated in the coil spring accommodation groove 19, and one end of the coil spring 16 abuts on the groove bottom 20.

  That is, as shown in FIG. 4B, when the tip 17 of the slider 15 protrudes, one end of the coil spring 16 accommodated in the rectangular hole 21 hits the groove bottom 20 and is compressed. As a result, the spring force of the coil spring 16 is biased by the slider 15 and works to retract the tip portion 17.

  FIG. 6 shows a flip-up operation of the sunglasses 3 attached to the curved frame 2 via the flip-up device 6. A metal fitting 23 is attached to the center of the upper side of the back side of the sunglasses 3, and the slider tip 17 of the flip-up device 6 is connected to the metal fitting 23 via the shaft pin 24, and (a) is shown in FIG. In this state, the sunglasses 3 are lowered and closed, and are parallel to the curved frame 2.

  (b) is a case where the sunglasses 3 are flipped up and kept almost horizontal. The metal fitting 23 attached to the sunglasses 3 forms contact holding surfaces 25a, 25b and 25c. In the case of (a), the contact holding surface 25a contacts the box upper end surface 26 of the flip-up device 6. Held. The metal fitting 23 is connected to the slider 15, and the slider 15 is in a pressure contact state by the spring force that the contact holding surface 25 a contacts the box upper end surface 26 and is urged by the spring force of the coil spring 16 accommodated. Is stably held in place.

  In the case of (b), the sunglasses 3 are flipped up horizontally, and the contact holding surface 25b of the metal fitting 23 is held in contact with and held on the box upper end surface 26 in a pressure contact state by a spring force. Therefore, the sunglasses 3 that are flipped up horizontally are not lowered and closed by themselves. (c) is a state in which the sunglasses 3 are further flipped up to stand upward. In this case, the abutment holding surface 25c of the metal fitting 23 abuts against the box upper end surface 26, and the spring force is urged to be in a pressure contact state, so that the sunglasses 3 is not lowered and closed.

  By the way, although the sunglasses 3 are targeted in the above embodiment as a flip-up type spectacle frame, it is free to attach a flip-up frame fitted with a general correction lens. Further, depending on the form of the flip-up frame, it can be directly mounted on the front part via the flip-up device.
