Skate having a hidden type size adjusting function

Abstract

A skate includes a wheel seat, a heel hard shell adjustably mounted on the wheel seat, a guide mechanism mounted between the wheel seat and the heel hard shell to guide movement of the heel hard shell relative to the wheel seat, and a size adjustment operation device mounted between the wheel seat and the heel hard shell. Thus, the user only needs to press the locking plate of the size adjustment operation device so as to adjust the position of the heel hard shell relative to the wheel seat, so that the size of the skate is adjusted easily and conveniently, thereby facilitating the user adjusting the size of the skate.

1 . A skate, comprising:

       2 . The skate in accordance with  claim 1 , wherein the guide mechanism includes a guide rail mounted on the wheel seat and a guide channel mounted on the heel hard shell and slidably mounted on the guide rail, so that the heel hard shell is slidable on the wheel seat.  
   
   
       3 . The skate in accordance with  claim 2 , wherein the guide rail is substantially dovetail-shaped.  
   
   
       4 . The skate in accordance with  claim 2  wherein the guide channel is substantially dovetail-shaped.  
   
   
       5 . The skate in accordance with  claim 2 , wherein the size adjustment operation device is located between the guide rail and the guide channel.  
   
   
       6 . The skate in accordance with  claim 1 , wherein the size adjustment operation device is hidden in the guide mechanism.  
   
   
       7 . The skate in accordance with  claim 1 , wherein the size adjustment operation device includes an adjusting plate mounted on the heel hard shell to move therewith and having a plurality of positioning holes, a locking plate pivotally mounted on the wheel seat and having a first end provided with a locking stub detachably inserted into and locked in either one of the positioning holes of the adjusting plate, and an elastic member pressed on a second end of the locking plate to push the locking stub of the locking plate to move toward the positioning holes of the adjusting plate at a normal state.  
   
   
       8 . The skate in accordance with  claim 7 , wherein the locking plate of the size adjustment operation device is elastic.  
   
   
       9 . The skate in accordance with  claim 7 , wherein the guide mechanism includes a guide rail mounted on the wheel seat and a guide channel mounted on the heel hard shell, the adjusting plate is hidden in the guide channel, the locking plate is hidden in the guide rail, and the elastic member is hidden in the guide rail.  
   
   
       10 . The skate in accordance with  claim 7 , wherein the elastic member is biased between the second end of the locking plate and the wheel seat.  
   
   
       11 . The skate in accordance with  claim 7 , wherein the first end of the locking plate is provided with a press portion to facilitate a user pressing the locking plate.  
   
   
       12 . The skate in accordance with  claim 7 , wherein a user's one hand holds the wheel seat, with his one finger being extended into the guide mechanism to press the locking plate of the size adjustment operation device to detach the locking stub of the locking plate from the respective positioning hole of the adjusting plate, thereby releasing the heel hard shell from the wheel seat, so that the heel hard shell is movable relative to the wheel seat to adjust the position of the heel hard shell relative to the wheel seat.  
   
   
       13 . The skate in accordance with  claim 6 , wherein a user's one hand holds the wheel seat, with his one finger being extended into the guide mechanism to operate the size adjustment operation device hidden in the guide mechanism.  
   
   
       14 . The skate in accordance with  claim 1 , wherein the heel hard shell is slidable on the wheel seat by guidance of the guide mechanism.
