         [0003]    2. Brief Description of Prior Arts 
         [0004]    Generally, eyeglasses available on the market have diversified functions and styles. According to the functions, Eyeglasses can be substantially divided into exercise eyeglasses, sun glasses, presbyopic and myopia eyeglasses for vision correction. Among them, the exercise eyeglasses are mainly for users to wear in strenuous exercises, so as to prevent the eyeglasses from falling off in vigorous activities such as jogging or jumping. Hence, stability in wearing is more emphasized in the exercise eyeglasses than ordinary eyeglasses. Current exercise eyeglasses structure mainly have lens mounting apertures provided on the frame thereof so as to allow the lenses to be mounted therein, and perforations are also formed on both sides of the frame so that a strap can combine its two ends in the perforations of the frame. When wearing the exercise eyeglasses, users can tie the strap of the exercise eyeglasses on the head. In this manner, users can avoid the eyeglasses from falling off in strenuous dynamic exercise such as jogging or playing ball by the strap tying around the head. 
         [0005]    When users want to engage in sedentary activities such as reading, word processing or attending formal occasions, they mostly wear ordinary eyeglasses having temples attached thereto, as ordinary eyeglasses having temples are more comfortable without the binding feeling of being tied tightly by the strap on head. Besides, ordinary eyeglasses look more aesthetic and are easier to match with costumes, so most ordinary users may purchase both exercise and ordinary eyeglasses to cope with both occasions of conducting dynamic as well as sedentary activities. Substantially, the exercise eyeglasses and the ordinary eyeglasses are designed in such a manner as to have the same elements and functions as well except the difference of arrangement of either a strap or temples. However, since users have to buy both types of exercise eyeglasses and ordinary eyeglasses, and this not only results in economic burden of users but also the exercise eyeglasses are often idled in the room corner when not in use, resulting in waste of resource.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
       [0025]    The technical contents, objects and effect of the present invention will become more apparent by the detailed description in conjunction with the accompanied drawings. 
         [0026]    Referring to  FIG. 1 , the eyeglasses assembly structure of the present invention mainly comprises a frame ( 1 ), two joint members ( 2 ), two locating members ( 3 ) and two temples ( 4 ). The frame ( 1 ) has two symmetrical lens mounting apertures ( 11 ) provided thereon for mounting two lenses, and two assembly slots ( 12 ) for joint members formed on the inner faces of both sides thereof. Each assembly slot ( 12 ) has an upper pivot hole ( 13 ) and a lower pivot hole ( 14 ) provided on the upper and lower walls respectively. 
         [0027]    Each of the two joint members ( 2 ) has an upper elastic element ( 21 ) and a lower elastic element ( 22 ) separately formed at the front end thereof, and pivots ( 211 ), ( 221 ) are provided respectively on the upper end face and the bottom end face of the upper elastic element ( 21 ) and the lower elastic element ( 22 ), so as to connecting pivotally with the upper pivot hole ( 13 ) and the lower pivot hole ( 14 ) of the assembly slot ( 12 ). Each of the two joint members ( 2 ) has a sliding groove ( 24 ) which is formed to extend from a gap ( 23 ) between the upper elastic element ( 21 ) and the lower elastic element ( 22 ), and a guiding rod ( 25 ) disposed vertically is assembled in each sliding groove ( 24 ). Further, the temples ( 4 ) are respectively formed integrally at the rear ends of the two joint members ( 2 ). 
         [0028]    Each of the two locating members ( 3 ) is assembled in the sliding groove ( 24 ) of the joint member ( 2 ), and a lengthwise guide slot ( 31 ) is formed at the center of the locating member ( 3 ), and the guiding rod ( 25 ) of the joint member ( 2 ) is positioned in the guide slot ( 31 ). Further, each of the locating members ( 3 ) has an opening ( 32 ) formed on one side so as to communicate with the guide slot ( 31 ). Moreover, each of the locating member ( 3 ) has a wave-shape knob unit ( 33 ) formed on one face corresponding to the inner side of the joint member ( 2 ). 
         [0029]    Configuring like this, when conducting assembly as shown in  FIG. 1 , each of the locating members ( 3 ) is placed into the sliding groove ( 24 ) of the joint member ( 2 ), and the vertically disposed guide rod ( 25 ) in the sliding groove ( 24 ) is inserted into the lengthwise guide slot ( 31 ) of the locating member ( 3 ) from the opening ( 32 ) formed at one side of the locating member ( 3 ), so that the locating member ( 3 ) and the joint member ( 2 ) can be assembled with each other. 
         [0030]    Next, each of the joint members ( 2 ) combined with the corresponding locating member ( 3 ) is assembled to the frame ( 1 ). Referring to  FIG. 2 , when assembling each joint member ( 2 ) to the frame ( 1 ), the upper and the lower elastic elements ( 21 ), ( 22 ) are pressed and thus deflected toward the gap ( 23 ), so that both the upper and the lower elastic elements ( 21 ), ( 22 ) are able to be placed into the assembly slot ( 12 ). In turn, the pressing on both the elastic elements ( 21 ), ( 22 ) is released and both the elastic elements ( 21 ), ( 22 ) are recovered back to their original positions. Thereby, the pivots ( 211 ), ( 221 ) provided respectively on the upper end face of the upper elastic element ( 21 ) and the bottom end face of the lower elastic element ( 22 ) are inserted into the upper and the lower pivot holes ( 13 ), ( 14 ) respectively provided on the upper and lower walls of the assembly slot ( 12 ), so that the joint member ( 2 ) and the temple ( 4 ) integrally formed at the rear end thereof can be connected pivotally with the frame ( 1 ). Alternatively, each joint member ( 2 ) is firstly inclined a certain angle so that the upper pivot ( 211 ) on the upper elastic element ( 21 ) can be inserted into the upper pivot hole ( 13 ) on the assembly slot ( 12 ) of the frame ( 1 ), and then the joint member ( 2 ) is shifted to the right place so that the pivot ( 221 ) on the lower elastic element ( 22 ) can be mounted on the lower pivot hole ( 14 ) on the assembly slot ( 12 ) of the frame ( 1 ). In this manner, the joint member ( 2 ) with the temple ( 4 ) integrally formed at the rear end thereof can be connected pivotally with the frame ( 1 ). 
         [0031]    Next, referring to  FIG. 3 , users press the wave shape knob unit ( 33 ) formed on the inner face of each locating member ( 3 ) so as to push the locating member ( 3 ) assembled in the sliding groove ( 24 ) of the joint member ( 2 ) toward the gap ( 23 ) formed between the upper elastic element ( 21 ) and the lower elastic element ( 22 ), and the locating member ( 3 ) is finally positioned between the upper elastic element ( 21 ) and the lower elastic element ( 22 ) to support the both elements. Simultaneously, the upper elastic element ( 21 ) and the lower elastic element ( 22 ) hold the locating member ( 3 ) by their elasticity, so that the upper elastic element ( 21 ) and the lower elastic element ( 22 ) are not deflected toward the gap ( 23 ) by the blocking of the locating member ( 3 ) held therebetween, as shown in  FIG. 4 . Therefore, the pivotal connection between the two joint members ( 2 ) and the frame ( 1 ) can be firmly maintained and the temples ( 4 ) integrally connected with the joint members ( 2 ) are also connected pivotally on the frame ( 1 ). Referring to  FIG. 5 , users can wear the eyeglasses with the temples ( 4 ) provided thereon for sedentary activities such as reading, word processing, or for attending formal occasion. 
         [0032]    On the other hand, when users want to conduct exercise like jogging, playing ball and to change the eyeglasses into exercise use, the two joint members ( 2 ) with the temples ( 4 ) integrally formed thereon can be detached from the frame ( 1 ). When each joint member ( 2 ) is to be detached, users press the wave-shape knob unit ( 33 ) formed on the inner face of each locating member ( 3 ) so as push the locating member ( 3 ) positioned at the gap ( 23 ) between the upper elastic element ( 21 ) and the lower elastic element ( 22 ) toward the sliding groove ( 24 ) of the joint member ( 2 ). When the joint member ( 2 ) completely enters the sliding groove ( 24 ), the gap ( 23 ) between the upper elastic element ( 21 ) and the lower elastic element ( 22 ) becomes void so that users can press and thus deflect the upper elastic element ( 21 ) and the lower elastic element ( 22 ) toward the gap ( 23 ). Then, the pivot ( 211 ), ( 221 ) respectively provided on the upper face of the upper elastic element ( 21 ) and the bottom face of the lower elastic element ( 22 ) can be retracted from the upper and the lower pivot holes ( 13 ), ( 14 ) respectively provided on the upper and lower walls of the assembly slot ( 12 ), so as to release the pivotal connection between the joint member ( 2 ) and the assembly slot ( 12 ) of the frame ( 1 ). In this manner, the disassembly between the joint members ( 2 ) with the temples ( 4 ) integrally formed thereon and the frame ( 1 ) is thus accomplished. 
         [0033]    Referring to  FIG. 6 , after the two joint members ( 2 ) with the temples ( 4 ) integrally formed thereon are detached from the frame ( 1 ), users can assemble the two joint members ( 2 ) with a strap ( 5 ) tied thereon to the frame ( 1 ). Each joint member ( 2 ) with the strap ( 5 ) tied thereon has a strap perforation ( 26 ) formed at its rear end for tying with the strap ( 5 ). In turn, according to the steps as stated above, the pivot ( 211 ), ( 221 ) respectively provided on the upper face of the upper elastic element ( 21 ) and the bottom face of the lower elastic element ( 22 ) of the joint member ( 2 ) are inserted respectively into the upper and the lower pivot holes ( 13 ), ( 14 ) provided respectively on the upper and lower walls of the assembly slot ( 12 ), and then the locating member ( 3 ) is pushed into the gap ( 23 ) formed between the upper elastic element ( 21 ) and the lower elastic element ( 22 ) so as to be held therein. Therefore, the pivotal connection between the pivot ( 211 ), ( 221 ) and the upper and the lower pivot holes ( 13 ), ( 14 ) can be steadily maintained. In this manner, users can wear the eyeglasses having the strap ( 5 ) tied thereon for vigorous dynamic activities. 
         [0034]    Configuring in this manner, by the design of the two joint members with either temples ( 4 ) or the strap ( 5 ) assembled at the rear ends, users can easily make the transformation into the eyeglasses with either the temples ( 4 ) or the strap ( 5 ) so as to form the type of ordinary eyeglasses or exercise eyeglasses. Therefore, there is no need to purchase both types of ordinary eyeglasses and exercise eyeglasses. Not only economic burden of purchasing both types of eyeglasses can be reduced but also material resource can be effectively employed by exploit only one eyeglasses as exercise eyeglasses or ordinary eyeglasses.
