Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to eyeglasses, more particularly, to a pair of eyeglasses including at least two frames which can be easily assembled with and disassembled from each other by a clipping device. 
         [0003]    2. Description of the Related Art 
         [0004]    U.S. Pat. No. 3,801,189 disclosed a frame of eyeglasses having a pair of lens-holding rings joined by a bridge split into two parts by a cut. The frame further includes a resilient removable clip fitted on the front of the bridge and engaging the upper and lower surfaces of the bridge so as to hold the two parts of the bridge together. The advantage of the resilient clip disclosed in the patent is that it enables the lenses of the eyeglasses to easily be changed or replaced. However, the resilient clip herein cannot engage a primary frame and a sealing member at the same time so that the eyeglasses assembled thereby can only be used in casual activities 
         [0005]    U.S. Pat. No. 7,520,604 provides a pair of eyeglasses including an outer frame, an inner frame and a sealing member including a sponge portion attached to the inner surface of the inner frame, and a leather portion attached to an inner surface of the sponge portion. The outer frame has a lens holder for holding lenses and side assembling ribs protruding from the side edges of the lens holder, each of the side assembling ribs having a side assembling groove formed between the side assembling rib and the lens holder. The inner frame has side edges, each of which can be inserted in the side assembling groove so that the inner frame can be detachably assembled with the outer frame. As described above, such eyeglasses not only can be used in both sports and casual activities but include structures by which the outer frame and the inner frame can be easily assembled with and disassembled from each other. However, the eyeglasses still has some disadvantages, for example, the structure designed to assemble and disassemble the outer and inner frames thereof is not easy to be produced and the problem that the lenses are difficult to be inserted into or removed from the outer frame is not solved yet. 
         [0006]    Accordingly, it needs to provide a new design which not only enables lenses of eyeglasses readily to be changed or replaced but also enables frames of a pair of multi-purpose eyeglasses to be easily assembled with and disassembled from each other. 
       SUMMARY OF THE INVENTION 
       [0007]    Thus, one objective of the present invention is to provide an improved clipping device for eyeglasses which can tightly hold and clip only one frame or multi-frames thereof. 
         [0008]    Another objective of the present invention is to provide a combination including a clipping device and at least two frames which can be easily assembled with and disassemble from each other by the clipping device. 
         [0009]    In order to accomplish these objectives, a clipping device according to one aspect of the present invention, which can tightly hold and clip only a primary frame or a primary frame and a secondary frame at the same time, comprises a base, an upper portion and a lower portion. The base includes a top side, a bottom side, a front surface and a back surface. The upper portion extends outwardly along a direction to which the front surface faces from the top side of the base. The lower portion also extends outwardly along the direction to which the front surface faces from the bottom side. The base, the upper portion and the lower portion are constructed in such a way that can jointly define a receiving room with multi-receiving sections to hold and clip only one frame or multi-frames at the same time. 
         [0010]    A pair of eyeglasses according to another aspect of the present invention, which can be used in both sports and casual activities, comprise a primary frame, a secondary frame and a clipping device. The primary frame includes a pair of lens-holding rings, a bridge connecting the rings and being split into an upper part and a lower part by a cut. The secondary frame includes a body having a pair of lens-holding units, a nose piece connecting said units and a pair of ring-shaped pad secured respectively on an inner surface of each of the lens-holding units. The clipping device comprises a base, an upper portion and a lower portion. The base, the upper portion and the lower portion are constructed to form a C-shaped receiving room. The receiving room includes an upper side, a bottom side and an inner side disposed therebetween. The upper and bottom sides of the receiving room are both stepped to form a plurality of receiving sections with different height to hold and clip only the primary frame, or, when needs, the primary and secondary frames at the same time.

Lenses  24 ,  26  are conventionally installed into rings  18 ,  20 . In this embodiment, bridge  22  is split into an upper part  222  and a lower part  224  by a cut  28  to enable these two rings  18 ,  20  to be simultaneously opened up by pulling in opposite directions so that lenses  24 ,  26  can be easily changed or replaced. A pair of temple bars or an adjustable elastic strap (not shown in the drawings) can be conventionally used to support primary frame  12  on the user&#39;s head. 
         [0020]    Secondary frame  14 , which is preferably constructed from the same material as primary frame  12 , is detachably assembled inside of primary frame  12  having the construction described above. Therefore, a user can wear either only primary frame  12  or the assembled primary frame  12  and secondary frame  14  according to necessity. 
         [0021]    Secondary frame  14  includes a body  30  having a pair of lens-holding units  302 ,  304  and a nose piece  306  connecting these units  302 ,  304 . Frame  14  further includes a pair of ring-shaped ocular pads  32 ,  34 , each of pads  32 ,  34  is respectively secured on the inner surface of each of lens-holding units  302 ,  304  of secondary frame  14 . 
         [0022]    Clipping device  16 , being made of materials having a substantially uniform modulus of elasticity, comprises a base  36 , an upper portion  38 , a lower portion  40  and a pair of nose pad  42 ,  44  extending downwardly from lower portion  40 . As shown in  FIG. 3 , upper portion  38  extends outwardly from the top side of base  36  in a direction to which front surface  362  of base  36  faces. Lower portion  40  extends outward from the bottom side of base  36  in a direction being the same as the direction that upper portion  38  extends. Base  36 , upper portion  38  and lower portion  40  jointly define a C-shaped receiving room  46  including an upper side  48 , a bottom side  50  and an inner side  52 . In the present embodiment, upper side  48  of receiving room  46  is stepped to form a first upper step  482  and a second upper step  484 , bottom side  50  of receiving room  46  is also stepped to form a first bottom step  502  and a second bottom step  504  so that C-shaped receiving room  46  forms a first clipping section  462  and a second clipping section  464 . First clipping section  462  is defined by first upper step  482 , inner side  52  of receiving room  46 , and first bottom step  502 . Second clipping section  464  is defined by second upper step  484  and second bottom step  504 . For contact with the wearer&#39;s nose, lower portion  40  is curved. 
         [0023]    When eyeglasses  10  having the above-mentioned construction is assembled, as shown in  FIGS. 1 and 4 , nose piece  306  of body  30  of secondary frame  14  is firstly inserted into first clipping section  462  of receiving room  46  so that secondary frame  14  is tightly clipped and held by clipping device  16 . And then, bridge  22  of primary frame  12  is pushed forward into second clipping section  464  of receiving room  46  so that primary frame  12  is also tightly clipped and held by clipping device  16  and at the same time upper part  222  and lower part  224  are urged toward each other. In this embodiment, for tightly assembling primary frame  12  and secondary frame  14  together. In this embodiment, Clipping device  16  is constructed in such a way that first receiving section  462  may have a size slightly smaller that of nose piece  306 , and second receiving section  464  may have a size slightly smaller that of bridge  22 . In addition, the distance between first upper step  482  and first bottom step  502  is smaller than that between second upper step  484  and second bottom step  504  so that said nose piece  306  of secondary frame  14  can be seated firmly in first clipping section  462 . 
         [0024]    As shown in  FIGS. 5 and 6 , the drawings depict a second pair of eyeglasses  60  including only a primary frame  62  and a clipping device  64  embodied in accordance with another aspect of the present invention. Primary frame  62  and clipping device  64  are similar to primary frame  12  and clipping device  16  disclosed above. The difference between them is that second upper step  642  of clipping device  64  is configured to have a dent  644  to be wedged in by a rib  664  disposed on upper part  662  of bridge  66  of primary frame  62  so that primary frame  62  can be firmly clipped and held by clipping device  64  without having a secondary frame.
