Title: Eyeglasses assembly structure

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to an eyeglasses assembly structure, especially to an eyeglasses assembly structure in which temples are fixed to a frame firmly and worn parts are easy to be replaced by arrangement of a rotatable switch member. 
     Description of Related Art 
     As shown in  FIG. 17 , a screwless eyeglasses assembly structure in which a frame and temples are connected without screws. An assembly portion  61  is formed on a lateral side of a frame  6  and provided with an upper and a lower tenons  62  while a mortise  71  is formed on both an upper end and a lower end of a pivot member  7 . The tenons  62  of the assembly portion  61  fit into the mortises  71  of the pivot member  7  correspondingly. A connection member  8  is provided and composed of a front end pivotally connected to the pivot member  7  and a rear end locked and connected with a fastening hole  91  disposed on a temple  9 . 
     Although the above screwless eyeglasses assembly structure not only solves the problem of easy-loosening of the screws of the conventional eyeglasses assembly structure over time but also has exquisite appearance, the screwless eyeglasses assembly structure still has shortcomings of high manufacturing cost caused by complicated structure and difficulty in disassembly. After being used for a period of time, wear and tear occur due to multiple times of folding and unfolding of the frame and the temple and replacement of the parts is required. The eyeglasses assembly structure available now is difficult to disassemble so that users usually throw away the whole eyeglasses instead of displacement of worn parts. This leads to a waste of materials and resources. 
     SUMMARY OF THE INVENTION 
     Therefore, it is a primary object of the present invention to provide an eyeglasses assembly structure in which a temple and a frame are connected firmly and worn parts are easy to be replaced by arrangement of a rotatable switch member. 
     In order to achieve the object, an eyeglasses assembly structure according to the present invention includes a pivot member not only pivotally connected to a first assembly portion of a frame but also inserted and mounted in a switch member. A first rib and a second rib are opposite to each other and arranged at a second assembly portion on a front side of a temple. The first rib is mounted into a first mounting groove at one end of the pivot member. A positioning flange is formed on the second rib and inserted through an opening of the switch member to be mounted in a second mounting groove on the other end of the pivot member. When the switch member is rotated an angle to be staggered with respect to the positioning flange of the second rib, the temple is securely connected to the frame, unable to be released from the frame. In order to replace parts, the temple and the frame are separated from each other by rotating the opening of the switch member to be aligned with the positioning flange of the second rib. Thereby the parts can be easily replaced assembled.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As shown in  FIG. 1 , an eyeglasses assembly structure mainly includes a frame  1 , a switch member  2 , a pivot member  3 , and a temple  4 . 
     The frame  1  consists of a first assembly portion  11  formed on a lateral side thereof, a pivot hole  12  arranged at the first assembly portion  11 , a groove  13  mounted on one side of the first assembly portion  11 , extending to and communicating with the pivot hole  12 , and a limit flange  14  disposed on one side of the first assembly portion  11  and located behind the groove  13 . 
     The switch member  2  which is a toothed disc is disposed on a top surface of the first assembly portion  11  of the frame  1  and composed of a through hole  21  and an opening  22 . The through hole  21  is corresponding to the pivot hole  12  on the first assembly portion  11  while the opening  22  is located on one side of the switch member  2  and communicating with the through hole  21 . 
     The pivot member  3  is provided with a stopping block  31  and a pivot  32  connected to the stopping block  3 . The pivot  32  is inserted through and pivotally connected to the pivot hole  12  on the first assembly portion  11  of the frame  1  and the through hole  21  of the switch member  2  while the stopping block  31  is abutting against and positioned by a bottom surface of the first assembly portion  11 . A surface of one end of the stopping block  31  and a surface of one end of the pivot  32  which are opposite to each other are respectively provided with a first mounting groove  311  and a second mounting groove  321 . 
     The temple  4  is composed of a second assembly portion  41  formed on a front side thereof, a first rib  42 , a second rib  43 , and a gap  44  formed between the first rib  42  and the second rib  43 . The first rib  42  and the second rib  43  are opposite to each other and disposed on the second assembly portion  41 . A positioning flange  431  is formed on the second rib  43  and facing the gap  44 . The first rib  42  is mounted into the first mounting groove  311  of the stopping block  31  of the pivot member  3  while the positioning flange  431  of the second rib  43  is inserted through the opening  22  of the switch member  2  to be mounted in the second mounting groove  321  of the pivot  32  of the pivot member  3 . The switch member  2  is able to be moved and rotated so that the opening  22  thereof and the positioning flange  431  of the second rib  43  are staggered or aligned with respect to each other. Moreover, a lateral surface of the second assembly portion  41  of the temple  4  and the limit flange  14  on the side of the first assembly portion  11  are abutting against and limited by each other. 
     The present eyeglasses assembly structure further includes a wrench  5  which consists of two jaws  51  opposite to each other and a recess  52  defined between the two jaws  51 . A shape of the recess  52  is corresponding to the switch member  2  so that the switch member  2  is held in the recess  52  of the wrench  5  by the jaws  51 . 
     While in use, as shown in  FIG. 2 , the pivot  32  of the pivot member  3  is inserted through and pivotally connected to the pivot hole  12  on the first assembly portion  11  of the frame  1 . The pivot hole  12  can be extended or reduced elastically due to the groove  13  disposed on one side of the pivot hole  12  of the first assembly portion  11  so that the pivot  32  is inserted through the pivot hole  12  smoothly and held firmly in the pivot hole  12 . The stopping block  31  of the pivot member  3  and the bottom surface of the first assembly portion  11  are abutting against and positioned by each other. Also refer to  FIG. 3 , then the switch member  2  is disposed on the top surface of the first assembly portion  11  and the pivot  32  of the pivot member  3  is inserted through the through hole  21  of the switch member  2 . The opening  22  of the switch member  2  is aligned with the second mounting groove  321  of the pivot  32  of the pivot member  3 . Next the first rib  42  of the second assembly portion  41  of the temple  4  is mounted into the first mounting groove  311  on a bottom surface of the stopping block  31  of the pivot member  3  while the positioning flange  431  of the second rib  43  is inserted through the opening  22  of the switch member  2  and mounted in the second mounting groove  321  on a top surface of the pivot  32  of the pivot member  3 . 
     Also refer to  FIG. 4 , the switch member  2  is held in the recess  52  of the wrench  5  by the jaws  51  so that the switch member  2  is rotated an angle by the wrench  5 . Thus the opening  22  of the switch member  2  and the positioning flange  431  of the second rib  43  of the temple  4  are staggered with respect to each other. And the positioning flange  431  of the second rib  43  of the temple  4  is locked in the through hole  21  of the switch member  2 , unable to be released. Thereby the present eyeglasses assembly structure has been completed easily and conveniently and the temple  4  is pivotally connected to the frame  1  firmly (as shown in  FIG. 5 ). A lateral surface of the second assembly portion  41  of the temple  4  and the limit flange  14  on one side of the first assembly portion  11  are abutting against and limited by each other when the temple  4  of the present eyeglasses assembly structure is unfolded. Thus the unfolded temple  4  at the optimal angle is provided. Owing to the pivot hole  12  able to be extended or reduced elastically, the tightness with which the pivotally connected temple  4  is folded and unfolded is maintained at the adequate levels. Therefore, not only hard folding and unfolding of the temple  4  caused by over-tightness, unexpected folding and unfolding of the temple  4  caused by loose connection can also be avoided. 
     Wear and tear occur due to multiple times of folding and unfolding of the temple  4  and the frame  1  after wearing the present eyeglasses assembly for a period of time so that replacement of parts is required. Refer  FIG. 6 , the user uses the wrench  5  to hold the switch member  2  in the recess  52  by the jaws  51  again and then rotate the switch member  2  until the opening  22  of the switch member  2  is aligned with the positioning flange  431  of the second rib  43  on the second assembly portion  41 . Also refer to  FIG. 7 , a force is applied to remove the positioning flange  431  of the second rib  43  on the second assembly portion  41  from the second mounting groove  321  on the top surface of the pivot  32  of the pivot member  3  to be released from the opening  22  of the switch member  2 . At the same time, the first rib  42  of the second assembly portion  41  is also pulled out of the first mounting groove  311  on the bottom of the stopping block  31  of the pivot member  3 . Thereby the frame  1 , the switch member  2 , the pivot member  3 , and the temple  4  are disassembled easily and conveniently for replacement of worn parts. There is no need to throw away the whole eyeglasses assembly structure and the waste of materials and resources is reduced. 
     Refer to  FIG. 8  and  FIG. 9 , another embodiment is revealed. In this embodiment, the positions of the switch member  2  and the pivot member  3  are mutually switched. The switch member  2  is arranged at a bottom surface of the first assembly portion  11  of the frame  1  while the pivot  32  of the pivot member  3  is inserted through the pivot hole  12  of the first assembly portion  11  and then the stopping block  31  is abutting against and positioned by a top surface of the first assembly portion  11 . The first rib  42  and the second rib  43  on the second assembly portion  41  of the temple  4  are also interchanged. Thereby the first rib  42  of the second assembly portion  41  is mounted in the first mounting groove  311  of the stopping block  31  of the pivot member  3 . The positioning flange  431  of the second rib  43  on the second assembly portion  41  is inserted through the opening  22  of the switch member  2  to be mounted in the second mounting groove  321  of the pivot  32  of the pivot member  3 . Thereby the temple  4  is able to be firmly fixed to or removed from the frame  1  easily and conveniently. 
     Refer to  FIG. 10  and  FIG. 11 , a further embodiment is disclosed. In this embodiment, the first assembly portion  11  of the frame  1  and the second assembly portion  41  of the temple  4  are interchanged so that the first assembly portion  11  is formed on a front side of the temple  4  and the second assembly portion  41  is formed on a lateral side of the frame  1 . Thereby the pivot  32  of the pivot member  3  is inserted through and pivotally connected to the pivot hole  12  of the first assembly portion  11  and the through hole  21  of the switch member  2  for pivot connection of the pivot member  3  with the first assembly portion  11  and the switch member  2  after the switch member  2  arranged at a top surface of the first assembly portion  11  of the temple  4 . And the stopping block  31  of the pivot member  3  is abutting against and positioned by a bottom surface of the first assembly portion  11 . Then the first rib  42  on the second assembly portion  41  of the frame  1  is mounted in the first mounting groove  311  disposed on the bottom of the stopping block  31  of the pivot member  3  while the positioning flange  431  of the second rib  43  on the second assembly portion  41  is inserted through the opening  22  of the switch member  2  to be mounted and positioned in the second mounting groove  321  on a top surface of the pivot  32  of the pivot member  3 . 
     Refer to  FIG. 12  and  FIG. 13 , a further embodiment is disclosed. In this embodiment, the switch member  2  and the pivot member  3  of the above embodiment are interchanged and then assembled. Thus the switch member  2  is disposed on a bottom surface of the first assembly portion  11  of the frame  1  while the pivot  32  of the pivot member  3  is inserted through the pivot hole  12  of the first assembly portion  11  and then the stopping block  31  is abutting against and positioned by a top surface of the first assembly portion  11 . Moreover, the first rib  42  and the second rib  43  on the second assembly portion  41  of the frame  1  are also interchanged. Thus the first rib  42  on the second assembly portion  41  is mounted in the first mounting groove  311  of the stopping block  31  of the pivot member  3  while the positioning flange  431  of the second rib  43  on the second assembly portion  41  is inserted through the opening  22  of the switch member  2  to be mounted in the second mounting groove  321  of the pivot  32  of the pivot member  3 . 
     Refer to  FIGS. 14-16 , a switch member  2  is cut from a front end of a wrench  5  by various ways such as punching and cutting, wire cutting, etc. An area left after the switch member  2  being cut forms a recess  52  of the wrench  5 . Thereby the manufacturing cost, materials and resources used are all reduced. A shape of the switch member  2  can be different geometric shapes such as a toothed disc (as shown in  FIG. 14 ), a polygon such as a rectangle (as shown in  FIG. 15 ) and a hexagon (as shown in  FIG. 16 ), an oval, etc. while a circle is not included.
