Description

  The present invention relates to a spectacle frame used to selectively use two types of lenses.

  As spectacles for selectively using two types of lenses, a spectacles main body is configured by attaching a vine to outer edge portions of a pair of holding frames that hold a correction (for example, hyperopic) lens by connecting via a bridge portion. There is one in which sunglasses is attached to the front side of the holding frame of the main body via a flip-up device (for example, Patent Document 1).

JP 2005-345880 A

  In the conventional example, in the normal state, the flip-up device is used to jump up the sunglasses so as to keep the horizontal state so that the object can be visually recognized using only the correction lens. The sunglass (colored lens) is superposed on the correction lens and used, but it is not always welcome in terms of appearance because it is necessary to keep unnecessary sunglasses in a normal state. Moreover, since the sunglasses are supported in a cantilever manner, it is difficult to secure the glasses in the normal position.

  The present invention was created with the object of providing a spectacle frame capable of selectively using two types of lenses, for example, paying attention to such disadvantages of the conventional example, which is not inconvenient in appearance and inconvenient to use. is there.

  In the spectacles in which a vine is foldably connected to a main body frame in which a pair of lens support portions are connected via a bridge portion, the vine is provided with a lens storage portion that is detachably assembled to the lens support portion. The lens support portion is formed by a ring body, and the ring body has an engagement groove at the lens peripheral edge provided on the inner peripheral edge, and a part of the bottom edge of the engagement groove. The lens insertion opening opened with a length of 2mm, and the storage part is made up of a thin case body with the upper surface open and the lens insertion opening. Thus, it is possible to provide a spectacle frame that is easy to use for properly using the two types of lenses.

  According to the present invention, the lens of the lens support part currently in use and the lens held in the storage part can be easily replaced with eyeglasses having a lens suitable for the purpose, and used and unused lenses. Can be held and carried at the same time, so it is easy to use and can provide glasses with a novel structure.

  The drawing shows an embodiment of an eyeglass frame according to the present invention. An eyeglass frame A according to an embodiment includes a main body frame 3 in which a pair of lens support portions 1, 1 are connected via a bridge portion 2, and the main body frame 3. And 6 and 6 which are connected to the armatures 4 and 4 protruding from the lens support portions 1 and 1 through hinge devices 5 and 5 so as to be foldable.

  The lens support portion 1 is configured by a horizontal rectangular ring body 1A that engages a peripheral end of a lens 8 with an engagement groove 7 provided on an inner peripheral edge and closes the inside, and a bottom edge of the engagement groove 7 7a is provided with a lens insertion opening 9 in which a part of 7a is opened with a length of the width of the lens 8 (lateral width in the embodiment).

  In the embodiment, the lens insertion port 9 is provided in the upper frame 1a portion of the ring body 1A constituting the lens support portion 1. However, the upper frame 1a is not necessarily required, and the ring body 1A is formed in a horizontal rectangular frame body. The present invention is not limited to a round shape such as a circle or an ellipse. There is no inconvenience, and the point is that there is no problem in supporting the lens 8 whose peripheral end is engaged with the engagement groove 7. The lens support portion 1 is configured by installing the locking means 10 of the lens 8 engaged with the engagement groove 7 on the ring body 1A so that the support of the lens 8 is securely held.

  The locking means 10 fastens the base portion 11a of the spring piece 11 to one end of the bottom edge 7a of the engaging groove 7 portion of the one side frame 1b of the ring body 1A on the insertion port 9 side, that is, the upper frame 1a side. The lens 8 is configured by engaging the peripheral end of the engaging groove 7 with the spring piece 11 and fitting into the ring body 1A. The side frame 1b, that is, the bridge portion 4 side is the other side frame 1c, that is, the hanging 6 It is pressed in the lateral direction and is held between the ring body 1A.

  The presence of the spring piece 11 is of course useful for more reliable holding of the lens 8, but the size of the lens 8 and the size of the ring body 1A that engages the lens 8 with the engaging groove 7 are different. Even in such a case, the lens 8 can be held, which has an advantage of absorbing an error in processing accuracy.

  A lens housing portion 12 is provided at an intermediate portion in the longitudinal direction of the temple 6, and a lens 8 to be attached to the lens support portion 1 is provided instead of the lens 8 that is detachably attached to the lens support portion 1. It is designed to be stored.

  The storage portion 12 is provided on one side wall 13a of the thin case body 13 having an opening on the upper surface, and the locking means 14 having substantially the same configuration as the locking means 10 provided on the lens support portion 1 (the base of the spring piece 11 is the one side wall). 13a), and the lens 8 inserted into the case body 13 from the insertion port 15 on the upper surface is secured by the locking means 10 in the case body 13. is there.

  16 is a window that opens in the thickness direction of the case body 13 (the thickness direction of the lens 8 housed in the case body 13). The fingertip is brought into contact with the lens 8 housed in the case body 13 through the window 16. The lens 8 is moved in the direction of the insertion port 15 to take out the lens 8 from the case body 13.

  The spectacle frame A is used as spectacles by engaging the lens 8 through the lens insertion ports 9 and 15 provided in the lens support portion 1 and the storage portion 12 respectively.
