Description

  The present invention relates to a rotatable connecting structure without screws and without a shaft between a fixing member and a rotating member of a spectacle. In particular, the present invention relates to a rotating connection structure using a magnetic force between a front frame and a temple, and a main spectacle frame and a sub spectacle frame.

  2. Description of the Related Art Conventionally, in a pair of spectacles, a structure in which a fixed member and a rotating member are connected to each other by a hinge connection with fine screws or pins has been used. For example, JP-A-60-169823 is mentioned as a general technical document.

JP-A-60-169823

  However, if the above-mentioned fine screws and pins are used and a large and long temple is connected so as to be able to rotate, stress concentrates on the screw part and the screw or pin breaks or bends, causing a serious accident. It was. Moreover, since the bearing part which receives a screw thread cannot be taken for a long time, it was inevitable that it loosened. In manufacturing, working with fine screws is wasteful and requires skill. Also, for general users, it was impossible to retighten the screws or replace the screws, and there was no such thing as changing the temples in such a state.

  In the present invention for solving the above-mentioned problems, first, there is a screw or shaftless rotation connecting structure between the fixing member and the rotating member of the glasses, and the fixing member is partially extended and bent. The two portions, the first magnetic attachment surface and the second magnetic attachment surface, are provided with through openings, and at least the rotating member made of a magnetic body is bent at the tip. And a body portion that is slightly wider than the distal end portion that follows, and the distal end portion provided with the magnetic body distal end portion or the magnet is inserted from the through-opening portion of the stationary member, and either one of the stationary member extension portions The rotating member is rotated and magnetically attached to the other magnetized surface, and the rotating member is rotated and magnetically attached to the other magnetized surface, so that the expanded state and the folded state are maintained. An attempt was made to provide a rotatable connecting structure for detaching members.

  Further, the fixing member is a front frame and the rotating member is a temple or a sub-glass frame, and both are detachably connected without using screws or pins.

  Manufacture and assembly of eyeglasses can be performed easily, thus reducing costs and delivery time. In addition, there are fewer failures when worn by the user, and the user can easily replace temples and secondary spectacle frames, greatly increasing the range of fashion designs.

  It is a screw or shaftless rotation connection structure between the fixing member and the rotation member of the spectacles, and there are two portions of the first magnetic attachment surface and the second magnetic attachment surface at the partially extended and bent portions of the fixation member. The magnetic attachment surface and the through-opening portion are provided, and the rotating member having at least a front portion made of a magnetic material has a bent tip portion and a main body portion slightly wider than the tip portion following the tip portion, The portion is inserted from the through-opening portion of the fixing member and is magnetically attached to one of the magnetic attachment surfaces of the fixing member extension, and the rotary member is rotationally magnetically attached to the other magnetic attachment surface. And a detachable rotation connecting structure for fixing and rotating a pair of spectacles, characterized in that the expanded state and the folded state are maintained. The embodiment will be described in detail with reference to the drawings.

  FIG. 1 is an exploded perspective view of an essential part of an embodiment of the present invention, in which a fixing member 10 (in this case, a front frame armor part) is formed in an extended bent shape, A first magnetized surface 30 is provided on the front side, and a second magnetized surface 31 is provided on the back side. In this case, the first magnetized surface and the second magnetized surface may be the same magnet, or may be separate magnets. Thus, a through opening 16 is provided in the bent portion 15. In the case of this figure, the tip portion 21 of the rotating member 20 (in this case, a temple) made of a magnetic material is formed at a height that can be almost inserted into the through opening 16 of the bending portion of the fixing member. The main body portion 22 at the base of the distal end portion 21 of the rotating member 20 is formed to have a width higher than that of the distal end portion 21 as a stopper. And the magnet 32 is arrange | positioned at the rotating member front-end | tip part 21 back surface.

  Then, as shown in the plan view of the main part of FIG. 2, the rotating member is inserted so that the rotating member tip 21 is fitted from the fixing member through opening 16. As a result, the first magnetized surface 30 on the fixed member side and the rotating member-side magnet 32 are attracted and held, and the rotating member 20 is held open. This is the state when wearing glasses. Then, when removing the glasses and folding the rotation member, the rotation is fixed by magnetic force so that the corresponding portion 23 inside the rotation member side 20 is attracted to the second magnetic attachment surface 31 on the fixing member side. The folded state is maintained.

  In addition, when the rotating member 20a is a non-magnetic material as shown in FIG. 3, the rotating side first adhering to the distal end portion 21a portion of the rotating member corresponding to the fixed member side first magnetized surfaces 30a and 31a. The magnetized surface 32a and the second magnetized surface 33 are provided. Further, the magnetized surface, that is, the arrangement of the magnets may be on the main body portion 33a and the fixed member side 34 of the rotating member. In addition, for example, as shown in FIG. 4, the tip 21b of the rotating member 20b may be slightly bent, and it goes without saying that such an example is also included in the application example of the present invention.

  FIG. 5 is an assembled plan view of the present invention. The temple (rotating member) 20c is stably held in both the opened state and the folded state. The expansion operation can be performed smoothly by magnetic force even without screws or pins. Also, when assembling, anyone can easily do this because it is only necessary to insert the temple tip into the through opening of the front frame (fixing member) 10c. Even if the temple is designed and exchanged, it is easy for the user to exchange. Further, as shown in the side view of FIG. 6, the vicinity of the joint 25 is not changed in appearance and appearance from the conventional glasses and has high design.

  Next, FIG. 7 shows a case where the fixing member is the main spectacle frame 40, the rotating member is the sub spectacle frame 50, an extended / bent portion is formed on the fixing member, and the bent tip portion 60 is formed. Are provided with a first magnetized surface 37 and a second magnetized surface 38, and a through opening 16a is provided on the front side of the bent extension. The first magnetized surface 37 and the second magnetized surface 38 are not limited to this location, and may be other locations in the extended bent portion. A magnet is provided over the front and back surfaces of the distal end portion 52 above the rotating member (secondary spectacle frame), and the base end portion is fixed on the rotating member. When the rotating member (sub-glass frame) 50 is not used, if the rotating member 50 is grasped with a finger or the like and rotated upward, the first magnetized surface 37 on the fixed member side is changed to the second magnetized surface 38. The rotating member side magnet 39 rotates while being attracted by a magnetic force, and comes into close contact. As a result, the rotating member (sub-glasses frame) is flipped up at an angle of about 90 degrees and the state is maintained. From this state, when using the rotating member (sub-glasses frame), it can be lowered with a finger or the like. When the rotating member (sub-glasses frame) is unnecessary, the rotating member (sub-glasses frame) can be easily removed by pulling it slightly forward with a finger and pulling it downward. However, in a natural state, it cannot be easily removed due to magnetic force and friction between members. And when fitting, it can be positioned by simply inserting it into the through opening 16a of the fixing member, and since the dimensions of the through opening 16a and the tip of the rotating member are matched, there is no deviation and it is difficult to come off.

  FIG. 8 shows an example of change when the fixing member is primary spectacles and the rotating member is secondary spectacles, and other design changes are within the scope of the present invention.

  FIG. 9 is a front view of the glasses, which is a position on the fixing member side (main glasses frame) to which the rotating member (secondary glasses frame) is attached, and the bridge portion 55 and the left and right frame upper portions 57 are preferable. Or, an armored portion may be used.

  FIG. 10 is an overall plan view of the spectacles of the present invention, and is a case where both the temple 20 and the sub-spectacle frames 50 and 50a are connected using the connecting structure of the present invention. It became possible to enjoy.

  Users will be able to enjoy various combinations of eyeglass styles, and their usage will be greatly expanded not only for prescription glasses but also for sunglasses.
