Multi-function shoe

Abstract

A shoe includes a first part wore by wearers and a second part which includes a C-shaped resilient plate which is fixed to an underside of the first part by its top. A first pin and a second pin are respectively connected to the front end and the rear end of the resilient plate. A base includes a front end which is pivotably connected to the first pin on the resilient plate and two lugs extend from the top of the rear end of the base. Each lug has an elongate slot and the second pin is movably engaged with the two elongate slots of the two lugs. The resilient plate is moved up and down when the second pin is moved within the elongate slots of the base.

1 . A shoe comprising:
 a first part which is adapted to be wore by wearers;   a second part having a C-shaped resilient plate and a top of the resilient plate fixed to an underside of the first part, a first connection unit connected to a front end of the resilient plate and a second connection unit connected to a rear end of the resilient plate, a first pin and a second pin connected to the first and second connection units, and   a base having a front end thereof pivotably connected to the first pin of the first connection unit and two lugs extending from a top of a rear end of the base, each lug having an elongate slot defined therethrough and the second pin movably engaged with the two elongate slots of the two lugs.   
   
   
       2 . The shoe as claimed in  claim 1 , wherein an outsole is attached to an underside of the base. 
   
   
       3 . The shoe as claimed in  claim 1 , wherein the first part includes a sole and two fastening units connected thereto. 
   
   
       4 . The shoe as claimed in  claim 1 , wherein the first part includes a sole and a vamp is connected to the sole. 
   
   
       5 . The shoe as claimed in  claim 1 , wherein two lugs extend from the top of the front end of the base and each lug includes a hole defined therethrough, the first pin pivotably extends through the two holes of the two lugs. 
   
   
       6 . The shoe as claimed in  claim 1 , wherein two pairs of rollers are rotatably connected to two ends of each of the first pin and the second pin. 
   
   
       7 . The shoe as claimed in  claim 1 , wherein the second part includes a blade extends from an underside thereof. 
   
   
       8 . The shoe as claimed in  claim 1 , wherein the second part includes four in-line rollers connected to an underside thereof. 
   
   
       9 . A shoe comprising:
 a first part which is adapted to be wore by wearers and includes a peripheral wall;   a second part having a peripheral wall which defines an open top, the peripheral wall of the first part being fixed to an inside of the peripheral wall of the second part;   a resilient plate received in the second part and including a backward bent portion extending from an underside of a front end thereof and a flexible protrusion extending from the underside of the rear end of the resilient plate, a pin extending through the flexible protrusion, and   a fixed plate connected to an inner end of the second part and including two lugs extending from a top of a rear end thereof and each lug having an elongate slot, the pin movably extending through the elongate slots of the two lugs, the backward bent portion contacting the top of the front end of the fixed plate so that the rear end of the resilient plate moves up and down by movement of the pin in the elongate slots.
