Separate protection component

Abstract

The present invention discloses a separate protection component, which comprises a first covering body and a second covering body. A first covering surface of the first covering is connected to a first bottom of the first covering to form a first receiving space. The second covering body is disposed in the first receiving space. A second covering surface of the second covering body is connected to the second bottom portion of the second covering body to form a second receiving space for receiving the ankle. When the first bottom is applied with an external force and the external force is not less than a maximum static friction coefficient, the contact surface moves in a direction so that the contact area between the contact surface and the sliding surface is changed from the first contact area to a second contact area.

What is claimed is: 
     
         1 . A separate protection component for protecting an ankle, the separate protection component comprising:
 a first covering body including a first covering surface and a first bottom portion, the first covering surface being connected to the first bottom portion to form a first receiving space; and   a second covering body disposed in the first receiving space, the second covering body including a second covering surface and a second bottom portion, the second covering surface being connected to the second bottom portion to form a second receiving space for receiving the ankle, the second covering surface being connected to the second bottom portion, wherein a sliding surface of the second bottom portions contacts a contact surface of the of the first bottom portion so the sliding surface overlaps the contact surface by a first contact area, the sliding surface forming a maximum static friction coefficient relative to the contact surface;   wherein, when the first bottom portion is applied with an external force and the external force is not less than the maximum static friction coefficient, the contact surface moves in a direction so that the contact area between the contact surface and the sliding surface is changed from the first contact area to a second contact area.   
     
     
         2 . The separate protection component according to  claim 1 , wherein the first covering surface is connected to the first bottom to form a first hole for connecting the first receiving space and the exterior of the first covering body. 
     
     
         3 . The separate protection component according to  claim 1 , wherein the second covering surface is connected to the second bottom to form a second hole for insertion of the ankle into the second receiving space. 
     
     
         4 . The separate protection component according to  claim 1 , further including a joint component disposed at the sliding surface, the contact surface or the combination thereof, the joint component having the maximum static friction coefficient. 
     
     
         5 . The separate protection component according to  claim 4 , wherein the joint component is a plurality of matric materials, the surface of one of the fabric materials being covered with a ring structure and the surface of another of the fabric materials being covered with a hood structure, the ring structure combining with the hood structure for forming a temporary tightening between the sliding surface and the contact surface. 
     
     
         6 . The separate protection component according to  claim 4 , wherein the joint component is of a pair structure and respectively disposed at the contact surface and the sliding surface for temporary tightening between the sliding surface and the contact surface. 
     
     
         7 . The separate protection component according to  claim 1 , wherein the second contact area is smaller than the first contact area. 
     
     
         8 . The separate protection component according to  claim 7 , wherein the area of the second contact surface is no greater than 5 square centimeters. 
     
     
         9 . The separate protection component according to  claim 1 , wherein the contact area between the contact surface and the sliding surface is changed from the first contact area to the second contact area, the second covering body separating from the first covering body. 
     
     
         10 . The separate protection component according to  claim 1 , wherein the sliding surface and the contact surface are at least one of smooth, nicked, grooved or granular shaped.
