         DESCRIPTION OF THE INVENTION  
         [0002]    The present invention relates generally to a “Shoe structure provided with interchangeable vamps”, especially to a shoe structure provided with interchangeable combinations and styles of vamps.  
           [0003]    According to the previous techniques, the connected portion between a shoe board and a vamp of general shoes including sandals, sports shoes or cotton shoes, etc. are usually sealed so that one is not able to make any changes of styles and patterns. The present invention has already gained the U.S. Pat. No.  6 , 418 , 643  named “Shoes structure provided with interchangeable accessories.” (hereafter called forgoing invention). Please refer to FIG. 1, the features of that forgoing invention are: inside the shoe board  1  there are a plurality of receiving spaces  1   a  which are set up with a plurality of separation pieces  2  and on the edges of certain vamps  3  there is a retaining piece  4 , which can be buckled and fixed into the separation pieces  2  so as to connect the shoe board  1  and the vamp  3 . And a shoe pad  5  is set up on the shoe board  1 .Another shoe pad  6  is set up in the combined construction in accommodation with the shoe pad  5  so as to fix it on the shoe pad  5 . By means of the techniques of the above forgoing invention, though different styles of vamp  3  can individually connect with the shoe board  1 , there are still regrets in practical that the scopes of the application are not wide enough. Now stated the details as follows:  
           [0004]    The feature of above foregoing invention can only be suitable for structure of sandals but totally not for shoes such as sports shoes, leather shoes, and informal footwear that have “totally wrapped vamp”. Therefore, the vamps of the shoes on sales now that have structure of wrapped vamp such as informal footwear and cotton shoes, etc. are not interchangeable. Besides, the most often broken portion of general shoes like informal footwear and sports shoes is at the front of a shoe between the shoe board and the vamp. After being used for a certain time, it will break because of losing functions of sticking and stitching, generally called “mouth opened” which needs improving.  
           [0005]    Thus, the primary objective of the present invention is to provide a “shoes structure with interchangeable vamp” that has been researched and developed, improved object to the said structure of the approved patent. Primarily set up with a push piece, covering board and a buckling board between the shoe board and the front of the vamp. The push piece and the covering board are set up in the inner side of the shoe board and primarily set up with a plurality of fixing board pillar at each side rib with a plurality of long holes on the board Surface of the cover board. The buckling board is set at the bottom portion of the vamp. Its back rib is set with a plurality of square-shape buckling base. By means of the buckling base set up into the long holes, the fixing board pillar on the push piece can be pushed and fixed with buckling base so as to be exactly combined the wrapped-type vamp with the shoe board.  
           [0006]    Another object of the present invention is to provide a plurality of buckling bases at both edges behind the board and at the backside behind the vamp provided with square-shape piece to be buckled with the buckling base, on which there are ribs and on the square-shape piece there are rib piece. With the combination between the square-shape piece and buckling base, the combination between the vamp and the shoe board will thus become more intensive and fixed.  
           [0007]    Please refer to FIG. 2 to FIG. 6, the present invention “shoes structure with interchangeable vamp” comprises a shoe board  10 , a shoe pad  20  and a vamp  30 , primarily provided with a fixing buckling device  40  between the shoe board  10  and the vamp  30  and a plurality of supplemental fixing buckling base  50 , which enables the shoe board  10  and the vamp  30  to be disassembled and combined randomly as well as to make its combination more fixed, which comprises: the shoe board  10  is a shoe-shape base, on which there are a plurality of fixing hole  11  and its inner side is provided with partial components to set up with a fixing buckling device  40  and supplemental fixing buckling base  50 .  
           [0008]    The shoe pad  20  is a smaller shoe shape relative to the shoe board. On its proper back edge is provided with a plurality of fixing pillar  21 , which can be fix into the fixing hole  11  on the shoe board  10  to fix the shoe pad  20  on the upper of the shoe board  10 , and in order to replace and take the shoe pad  20 , is provided with a strap  22  at the proper backside of the shoe pad  20 .  
           [0009]    The vamp  30  is a shoe shape wrapped at its side edge. At the proper bottom portion is provided with partial fixing function between the fixing buckling device  40  and supplemental fixing buckling base  50 .  
           [0010]    The fixing buckling device  40  comprises a put-in base  41 , a push piece  42 , a covering board  43  and a buckling board  44 :  
           [0011]    The put-in base  41  is a tub piece shape provided at the front of the inner side of shoe board  10  and on its proper portion is provided with a defining piece  411  used for the fixing of the push piece  41 .  
           [0012]    The push piece  42  is in a long square shape. On its proper portion is provided with a hollow part  421  fixed with the defining piece  411  so as the make the push piece  42  slip into the put-in base  41 . And each side edge around it is provided with a plurality of the fixing board pillar  422  in an irregular order.  
           [0013]    The covering board  43  covers on the push piece  42  in a relative shape to the put-in base  41 . At the portion that the board faces the fixing board pillar  42  is provided with a plurality of long hole  431 .  
           [0014]    The buckling board  44  is fixed at the proper bottom portion of the vamp  30 . At each long hole  431  at the back board facing the covering board  43  is provided with a plurality of square-shape buckling base  441 , which center portion is hollow and the outer portion is sealed just to insert the long hole  431 .  
           [0015]    The supplemental fixing buckling embodiment  50  comprises a buckling base  51  and a square-shape buckling board  52 . At both side and the back of the shoe board  10  is provided with a buckling base  51  in a shoe shape, which proper inner side is provided with a buckling-g piece  511  and formed a rib on that buckling piece  512 . The square-shape buckling board  52  is fixed in the central and back portion of the vamp  30 , on which inner side is provided with a rib piece  521 , which can be exactly buckled and fixed with the rib  512  while the square-shape buckling board  52  is buckled in the buckling base  51 .  
           [0016]    By means of the above said components&#39; combination, not only one can combine and disassemble the vamp  30  such as informal footwear, cotton shoes, etc. which is in a wrapped shape with the shoe board  10 , but also can enhance the strength of the combination and make it more convenient to be assembled.  
           [0017]    Please further refer to FIG. 7 and FIG. 8, the technical assembling and applicable means of the present invention are: when each components of the fixing buckling device  40  and the supplemental fixing buckling embodiment  50  are provided at the pre-fixing position of the vamp  30  with the shoe board  10 , place the buckling set  441  on the vamp  30  into the long hole  431  of the board  43  and then push the push piece  42  to let the fixing board pillar  422  of the push piece  42  to fix into the hollow part of the buckling set  441  and set across the buckling set  441  to let go the long hole  431 . Thus, one can accomplish the front combination of the shoe board  10  and the vamp  30 . The set the square-shape buckling board  52  of the vamp  30  into the buckling base to be buckled so as to complete a closely combination of the central and back portion between the shoe board  10  and the vamp  30 . In the final, insert the shoe pad  20  onto the shoe board  10  of the vamp  30 .  
           [0018]    As shown in FIG. 6, when the square-shape buckling board  52  is buckled in the buckling base  51 , it is a type of buckling and fixing with buckling piece  511  and is the rib  512  on the bucking piece  511  and shows a combination structure of being wedged and stuck up with the rib piece  521  of the buckling board  52 . In this way, it will become more fixed and denser. Besides, it will become more convenient and taster to assemble and disassemble the vamp  30  and the shoe board  10 .  
           [0019]    On the contrary, when disassembling and replacing the vamp  30 , first pull the strap  22  on the shoe pad  20  and take out the shoe pad  20 . Then, depart the square-shape buckling board  52  from the buckling base  51 . The fixing buckling device  40  allows the push piece  42  pushed in an opposite direction so that the buckling set  441  will depart from the long hole  431 . Thus, it will also depart the vamp  30  and the shoe board. There is one thing needed to explain further, when the square-shape buckling board  52  depart from the buckling base  51 ,one only needs to pull and twist a little so as to achieve the purpose of disassembling vamp  30  in a convenient and fast way.  
           [0020]    Furthermore, as shown from FIG. 9 to FIG. 14, the major feature of the present invention is structure of interchangeable styles of wrapped style of vamp  30 . Thus, those vamps which are total wrapped (as shown in FIG. 9 and FIG. 10) or half wrapped (as shown from FIG. 11 to FIG. 14) are applicable to the structure of the present invention so the users can have changeable choices in wearing footwear. And with the a shoe board  10  accompanies a variety of colors and styles of vamp  30  which enable the users to choose freely and lead to an increasing sales from which the manufacturers can then gain more sales.  
           [0021]    In addition, in the respect of the practical examples of the present invention, the buckling base  51  of the supplemental fixing buckling embodiment  50  can be applied on a board base in an arrangement of a shoe pattern, or can be applied on wherever on the shoe board  10  in an individual or pair type, or further applied on the covering board  43  of the fixing buckling device  40  to collocate a sandal&#39;s vamp  30  assemble. Please refer to FIG. 3 and FIG. 15 and FIG. 16, at the proper both sides of the covering board  43  of the fixing buckling device  40  can be provided with the buckling base  51 . Thus, when user wishes to change the vamp  30  of sandal&#39;s style, one can directly buckle the square-shape board on the vamp  30  into proper buckling base  51  and then put the shoe pad  20  on the shoe board  10 , By way of this, user can change the wrapped type shoe into a sandal. FIG. 15 and FIG. 16 show when the fixing buckling device  40  has not buckled on the shoe board  10 , the shoe board  10  can still be provided with sandal style&#39;s vamp  30  buckling which are more changeable and practical in applications. Of course, the quantity and position of the square-shape buckling board  52  can be adjusted in a best way according to the patterns and styles of the vamp  30 .  
           [0022]    In conclusion, the present invention “Shoe structure provided with interchangeable vamps” is indeed a design with both practical and progressive features which totally conform to the important conditions of patent application. Herein apply for and hope it will be examined and approved soon.
