Description

  The present invention relates to a flip-up type eyeglass that can be flipped up by rotating a front part around a bridge (connecting member) and that the field of view is not blocked by the flipped-up frame.

  In recent years, front-type glasses and flip-up type glasses are frequently used. However, the front-type glasses are configured such that another front frame is detachably attached to the front of the front portion. On the other hand, the flip-up glasses have a structure in which the flip-up frame can be lifted upward as needed without attaching or removing the flip-up frame.

  The front-type glasses and the flip-up type glasses have advantages and disadvantages, and each can be selected according to preference. Although the present invention is directed to flip-up glasses, there are various mechanisms for flipping up the flip-up front part. However, the basic structure is the same, and the structure is such that it can be rotated upward via a shaft provided on the front frame and does not fall so as to be held at a predetermined angle.

Japanese Patent Application Laid-Open No. 9-292592 is a flip-up type spectacle frame equipped with a front front frame that can be flipped up in front of the spectacles, and obstructs visibility even when looking far away. It is a flip-up type eyeglass frame that is not subject to fatigue.
Therefore, the front front frame is attached to the back front frame through a joint so that it can be opened and closed with two degrees of opening, and the joint is formed by connecting both joint pieces through a shaft. Are fixed to the front and front frames, respectively, and one joint piece is provided with a ball urged by a spring force so that the ball is pressed into a recess formed in the other joint piece.

Japanese Patent Application Laid-Open No. 2003-121803 “Splash-up type spectacle frame” can smoothly rotate the front frame, can be easily maintained at an arbitrary rotation angle, has excellent durability, and This is a flip-up type spectacle frame in which a pair of front frames can be prevented from overlapping each other as in the conventional flip-up type.
Therefore, when the wearer rotates the main front frame and moves it upward from the front, the rotating shaft connected to the main front frame is connected to the friction resistance between the resin pipe and the bridge housing, and the elasticity of the leaf spring. Rotate while resisting force. And when the wearer wants the angle, when the rotation of the main front frame is stopped, the resin pipe receives the frictional resistance between the resin pipe and the bridge housing, and the elastic biasing force from the leaf spring, That is, the rotating shaft is held at that position.

  Japanese Patent Application Laid-Open No. 2007-328307 “Repelling Eyeglass Frame” is a mechanism that rotates so that even if the movable frame is loosened or rattled, it can be restored to a good operating state by screwing a popular product. A coil spring is built in, and the stress of the coil spring can be adjusted by a screw attached to the outside. In addition, for the purpose of preventing wear of the rotating motion shaft and stabilizing the movable frame at a predetermined position, the rotational motion shaft is not slipped on the rotational motion shaft so that it is supported by the stress of the coil spring, not the frictional resistance. A recess is provided.

  In addition to these, “glasses” according to utility model registration No. 312380, “spring spring-up frame” according to Japanese Patent Application Laid-Open No. 2009-163046, and the like are variously known. As described above, various conventional flip-up glasses have known flip-up mechanisms, but the visual field may be blocked when the flip-up front part is flipped up. In particular, in the case of glasses worn when playing golf or baseball, the front portion has a large curved shape so as not to cause a large gap between the front portion and the face. Therefore, the flip-up front portion attached to the front surface of the front frame is also greatly curved.

Since the flip-up frame is swung up by turning around an axis provided at the center of the upper end, both ends of the flip-up frame hang down downward, and the view is partially blocked. Of course, there is no problem if the front part is flipped high so that the field of view is not obstructed, but when playing golf or baseball, it is normal to wear a hat. End up. For this reason, it is preferable that the field of view is not obstructed in a state of being raised up to a substantially horizontal position without being raised up.
"Spring-up type spectacle frame" according to Japanese Patent Application Laid-Open No. 9-292592 "Splash-up spectacle frame" according to Japanese Patent Application Laid-Open No. 2003-121803 “Repelling type eyeglass frame” according to Japanese Patent Application Laid-Open No. 2007-328307 “Glasses” related to Utility Model Registration No. 3124380 “Spring-up frame by spring” according to JP 2009-163046 A

  As described above, the conventional flip-up type glasses have the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides the flip-up type glasses in which the field of view is not obstructed by the flip-up front part that is flipped up to a substantially horizontal position.

  In the flip-up glasses according to the present invention, a flip-up front part is attached to the front of the front frame, and the flip-up front part turns around a shaft provided at the center of the front frame and is flipped upward. In the present invention, the flip-up front part is constituted by two pieces, that is, a left front part and a right front part, which are connected via a shaft. Therefore, the left and right front portions can swing through the shaft, and the crossing angle of the left and right front portions can be changed.

  Here, the front frame to which the flip-up front part is attached has a configuration in which both the rims are fitted and the lens is fitted in the same manner as the flip-up front part, or when the front frame is configured as one wading without the rim. and so on. The flip-up front part generally has a structure with a rim and a lens or sunglasses fitted thereto, but the rim is not provided with a ring-shaped full rim, half rim, or rim, and both lenses are screwed to a central connecting member. It can also be configured.

  By the way, the left and right front portions are attached to both joint pieces that swing about the shaft, and the shaft portion is provided with a spring, and the force of the spring is urged to the left and right front portions to maintain a predetermined crossing angle. . That is, the spring force is urged so that the left and right front parts come into contact with the front frame and are stabilized. If the flip-up front portion is flipped upward, the joint piece hits the upper surface of the front frame, and the left and right front portions are swung up and lifted. The upper surface of the front frame is shaped so that the joint piece hits and the left and right front parts swing upward. Here, by forming a fine uneven surface on the sliding surface of the left and right joint pieces, it is possible to stabilize without fluttering without providing the spring.

  The flip-up glasses according to the present invention can flip up the flip-up front part as necessary. In this case, the left and right front parts constituting the flip-up front part can swing around the axis, and the joint piece that attaches the left and right front parts hits the front frame and is pushed up. The field of view is not obstructed even in the state of being raised almost horizontally.

  That is, even a flip-up front part that is well-curved and conforms to the face can swing upward as soon as it is flipped up. Then, if the left and right front portions that are flipped up are lowered, the springs provided on the shaft can be brought into contact with the front surface of the front frame to be in a predetermined position. In addition, the left and right front portions that are bounced upward are stabilized by the joint piece resting on the upper surface of the front frame by the spring provided on the shaft, and do not fall by themselves.

Represents. In the figure, 1 is a wading, 2 is a crane, 3 is a flip-up front part, and the wading 1 in the plan view of FIG. 1 is curved in an arcuate shape. , 2 are attached so that they can be folded.

  The temple 2 is connected to the wading 1 by a hinge 4, but when the temple 2 is opened, a stopper 5 that overlaps the surface of the tip of the wading 1 extends to restrict the degree of opening of the vine. The wading 1 in the figure is a form of a front frame of the flip-up glasses, and is configured as a single bow-shaped member without a rim to which a lens fits. Moreover, it can also be set as the front frame which has a rim | limb like a flip-up type front part as needed.

  For example, there may be a case where a near-eye lens is fitted to the front frame and sunglasses are fitted to the flip-up type front portion. Two nose pads 20 and 20 are attached in pairs to the center of the wading 1 shown in the figure, and when the flip-up glasses are put on the face, the nose pads 20 and 20 The wading 1 is supported by the side. Both vines 2 and 2 hit the side of the face and extend to the ears.

  By the way, a flip-up front part 3 is attached to the wading 1 and can be swung up through a joint 6 by turning up. The flip-up front portion 3 is the same as the front portion of general glasses, and is attached to the wading 1 via the joint 6 so that the front portion can be flipped upward when it is unnecessary. The joint 6 is provided at the center of the wading 1 and is connected to the center of the flip-up front portion 3.

  On the other hand, the flip-up front part 3 has a right front part 8 and a left front part 9 on both sides around a screw shaft 7 provided in the center. The right front part 8 and the left front part 9 are centered on the screw shaft 7. Can swing. That is, the right front portion 8 is attached to the right joint piece 10, the left front portion 9 is attached to the left joint piece 11, and the left and right joint pieces 11, 10 swing around the screw shaft 7. The left front part 9 and the right front part 8 attached to the left and right joint pieces 11 and 10 are configured to swing and change the crossing angle.

  By the way, the right front portion 8 and the left front portion 9 are connected to both ends of the half rim 12 with water threads 13 fastened as shown in the rear view of FIG. It is held by the thread 13. Of course, the form of the left and right front portions 9 and 8 is not limited to the structure in which the lens 14 is held by the half rim 12 and the water thread 13 as shown in FIGS. 2 and 3, and a ring-shaped full rim may be used. Furthermore, it is also possible to directly fix the lenses 14 and 14 to the joint pieces 10 and 11 without using a rim.

  The wading 1 that constitutes the flip-up glasses of the present invention is greatly curved and has a shape that fits on the face. Then, both the vines 2 and 2 can sandwich the occipital region from the side of the face, and at that time, the curved wading 1 is deformed to some extent, and a pressing force can be applied to the side surface and the occipital region. Therefore, it can be worn stably without being displaced when playing sports such as golf or baseball.

  The flip-up front part 3 that is attached to the front side of the wading 1 and is flipped up includes a right front part 8 and a left front part 9, and can swing around the screw shaft 7. Therefore, the screw shaft 15 is attached to the screw shaft 7 so that the right front portion 8 and the left front portion 9 do not flutter, and the right joint piece 10 to which the right front portion 8 is attached, and the left front portion. The left joint piece 11 to which the portion 9 is attached is in contact with the front face 18 of the wading 1 in a state where the spring force is urged.

  Similarly, as shown in FIG. 4, when the flip-up front portion 3 is flipped up, the right joint piece 10 and the left joint piece 11 abut against the upper surface 19 of the wadding 1 in a state where the spring force is urged. ing. And the wading 1 forms the smooth mountain shape (convex shape) on both sides centering on the coupling 6 provided in the center. Therefore, when the front part 3 is flipped up as shown in FIG. 4, the tip of the right joint piece 10 hits the upper surface 19 of the wading 1, and the tip of the left joint piece 11 similarly touches the upper surface 19 of the wading 1. By hitting, the right front portion 8 and the left front portion 9 can swing and the side end portions can rise upward.

  That is, when the flip-up front portion 3 is flipped up, the side end portions of the right front portion 8 and the left front portion 9 are not positioned below the wading 1. Therefore, the field of view is not blocked by the flip-up front part 3. When the right front portion 8 and the left front portion 9 shown in the plan view of FIG. 1 are flipped upward while maintaining the positional relationship between the right front portion 8 and the left front portion 9, The view is blocked by being located below. Therefore, according to the present invention, the left and right front portions 11 and 10 are swingably attached around the central screw shaft 7, so that the spring can be positioned above the wading 1 when the spring is flipped upward.

  FIG. 5 is an enlarged view of the central portion of FIG. 2. The right joint piece 10 and the left joint piece 11 are stepped to engage with each other and are connected by a screw shaft 7.
