Description:
FIELD OF THE INVENTION 
     The present invention relates to an improved shoe and particularly a shoe that has a replaceable vamp and insole. 
     BACKGROUND OF THE INVENTION 
     A conventional shoe, such as the one shown in FIG. 1, generally has a vamp made by stitching, then the vamp and insole are glued and bonded together, then the vamp and the outsole are glued and compressed to complete the fabrication of the shoe. The shoe made by gluing and compressing lacks strong bonding power and tensile resistance. The vamp and insole and outsole are prone to separate and fall apart. 
     Moreover, the shoe with the vamp and insole and outsole fixedly bonded by gluing cannot be replaced by individual parts. They have limited practicality and interchange capability. 
     SUMMARY OF THE INVENTION 
     In view of aforesaid disadvantages, it is therefore a primary object of the invention to provide a shoe that has anchor struts and anchor bores formed respectively on the lower surface of the insole and upper surface of the outsole to allow the insole and outsole assembling and dismantling freely as desired. 
     Another object of the invention is to provide a plurality of housing chambers on the upper surface of the outsole for holding anchor blocks to facilitate assembly and disassembly of the vamp. 
     A further object of the invention is to provide various types of anchor blocks to fasten the vamp. 
     To attain the foregoing object, the shoe according to the invention mainly includes an outsole, an insole, a vamp and a plurality of anchor blocks. The outsole and insole are fastened through anchor bores and anchor struts to allow the insole be detached and replaced. The outsole has a plurality of housing chambers and a storing chamber for holding respectively anchor blocks and a dismantle tool. The anchor block has a wedge trough to engage with the latch section of the vamp to allow the vamp be removed and replaced whenever desired. 
     The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to FIGS. 2 through 9, the shoe according to the invention mainly consists of the following elements: 
     an outsole  10  which has a plurality of anchor bores  11 , a plurality of housing chambers  12  and a storing chamber  13  formed on the upper surface. Each anchor bore  11  has an annular jutting ring  110  (as shown in FIG.  5 ). The housing chamber  12  may hold and engage with an anchor block  20 . The storing chamber  13  is to house a dismantle tool  30  which is formed substantially in an inverse Y-shape with an upper pry section  31  and a lower pry section  32 ; 
     an insole  40  mounted to the upper surface of the outsole  10  includes a plurality of anchor struts  41  located on the lower surface mating the anchor bores  11  of the outsole  10 . Each anchor strut  41  has an annular indented groove  410  mating and engageable with the annular jutting ring  110  of the anchor bore  11  (as shown in FIG.  5 ); 
     a vamp  50  fastenable to the outsole  10  has latch sections  51  located at the ends thereof. Each latch section  51  has an extensible section  510 ; and 
     a plurality of anchor blocks  20  each has a flange  21  to engage with the outsole  10  and to conceal securely in the housing chamber  12 . The anchor block  20  further has a wedge trough  22  and a push pin  23 . The wedge trough  22  has a retain edge  220  (as shown in FIG.  7 ). 
     When to assemble the invention, insert the latch section  51  of the vamp  50  into the wedge trough  22  of the anchor block  22  with the extensible section  510  of the latch section  51  latching to the retain edge  220  (as shown in FIG. 7) to allow the vamp  50  fastening securely to the peripheral edge of the outsole  10 . 
     Then dispose the anchor blocks  20  into the housing chambers  12  and the dismantle tool  30  into the storing chamber  13 . Then wedge the anchor struts  41  of the insole  40  into the anchor bores  11  of the outsole  10  with the annular indented groove  410  engaging with the annular jutting ring  110  (as shown in FIG. 5) to allow the insole  40  fastening to the outsole  10 . 
     When to disassemble, pull the insole  40  slightly upwards to detach the anchor struts  41  from the anchor bores  11  for separating the insole  40  from the outsole  10 . Then replace the insole  40  of different materials or styles or colors as desired. 
     When the anchor block  20  is held in the housing chamber  12 , there is extra space in the housing chamber  12  to receive users&#39; finger for depressing the push pin  23  towards the latch section  51  to separate the extensible section  510  from the retain edge  220 , then the latch section  51  may be removed from the wedge trough  22  (as shown in FIG.  7 A), and the vamp  50  may be separated from the outsole  10  for replacing the vamp  50  of different materials or styles or colors. 
     By means of the construction and method set forth above, the vamp and insole may be changed and replaced freely as desired. 
     FIG. 8 shows another embodiment of the invention with a different anchor block  20 ′ and latch section  51 ′ from the previous embodiment. The anchor block  20 ′ also has a flange  21 ′ to engage with the outsole (not shown in the drawing) and conceal securely in the housing chamber (not shown in the drawing) of the outsole. The anchor block  20 ′ also has a wedge trough  22 ′ and push pin  23 ′ and an elastic retain section  220 ′. The elastic retain section  220 ′ has a plurality of first latch teeth  24 ′ formed on the exterior surface to match and engage with a plurality of second latch teeth  510 ′ formed on the inner surface of the latch section  51 ′. When to disengage the latch section  51 ′ from the elastic retain section  220 ′, depress the push pin  23 ′ against the elastic retain section  220 ′, the latch section  51 ′ may be disengaged from the elastic retain section  220 ′ for moving the vamp  50  away. 
     The dismantle tool  30  may be stored in the storing chamber (not shown in the drawing) of the outsole (also not shown in the drawing). The upper pry section  31  may be wedged between the elastic retain section  220 ′ and the latch section  51 ′ to depress the elastic retain section  220 ′ inwards, the latch section  51 ′ may be disengaged from the elastic retain section  220 ′ easily. 
     FIG. 9 shows yet another embodiment of the invention. The anchor block  20 ″ also has a flange  21 ″ to engage with the outsole (not shown in the drawing) and conceal securely in the housing chamber (not shown in the drawing) of the outsole. The anchor block  20 ″ also has a wedge trough  22 ″ and an elastic retain section  220 ″. The elastic retain section  220 ″ has a plurality of first latch teeth  24 ″ formed on the exterior surface to match and engage with a plurality of second latch teeth  510 ″ formed on the inner surface of the latch section  51 ″. When to disengage the latch section  51 ″ from the elastic retain section  220 ′, wedge the lower pry section  32  of the dismantle tool  30  between the elastic retain section  220 ″ and the latch section  51 ″ and depress the elastic retain section  220 ″ inwards, the latch section  51 ″ may be disengaged from the elastic retain section  220 ″ easily. 
     By means of any of the anchor blocks  20 ,  20 ′ and  20 ″ set forth above, the vamp  50 ,  50 ′ and  50 ″ may be changed and replaced as desired.
