Ratchet belt of binder for sports

Abstract

The present invention relates to a ratchet belt for sports capable of providing an abrasion prevention part for preventing a toothed part of a ratchet belt from being worn away due to a repeated use in a ratchet belt capable of fixing boots to a binder by tightening in a step-by-step manner based on a tooth interval of a ratchet belt when a user wears a sports binder, and a buckle is tightened. The ratchet belt for sports comprises a concave and convex shaped ankle in which a slope surface slanted similarly with a slanted surface of the ratchet belt or slanted more than the same and a roughly upright surface are repeatedly formed, wherein said ankle is press-formed, and the ankle is insert-formed, so that a part of the upper side of the upright surface is exposed to the outside and is directly engaged with an engaging protrusion of the buckle.

1 . In a binder operating as an apparatus in which a ratchet belt having a plurality of teeth formed on an upper surface of the same is engaged to a ratchet type buckle having an engaging protrusion, wherein a slanted surface is formed in one side of teeth of a ratchet belt, and a vertical surface is formed in the other side of the teeth, and a ratchet belt is not escaped from a buckle in such a manner that an engaging protrusion is caught by the vertical surface, and the length of the ratchet belt is adjusted in a step-by-step method by tightening the buckle, an improved ratchet belt for sports, comprising: 
 a concave and convex shaped ankle in which a slope surface slanted similarly to a slanted surface of the ratchet belt or slanted more than the same and a roughly upright surface are repeatedly formed, wherein said ankle is press-formed, and the ankle is insert-formed, so that a part of the upper side of the upright surface is exposed to the outside and is directly engaged with an engaging protrusion of the buckle.    
     
     
         2 . The belt of  claim 1 , wherein a plurality of holes are formed in the slope surface, so that the upper and lower surfaces of the ankle communicate with each other, and the ankle is stably fixed to the ratchet belt through the holes.  
     
     
         3 . The belt of  claim 1 , wherein said ratchet belt is injected with a polyurethane material, and the slope surface is inwardly curved, so that the polyurethane is stacked thickly on an upper surface of the ankle.  
     
     
         4 . In a binder operating as an apparatus in which a ratchet belt having a plurality of teeth formed on an upper surface of the same is engaged to a ratchet type buckle having an engaging protrusion, wherein a slanted surface is formed in one side of teeth of a ratchet belt, and a vertical surface is formed in the other side of the teeth, and a ratchet belt is not escaped from a buckle in such a manner that an engaging protrusion is caught by the vertical surface, and the length of the ratchet belt is adjusted in a step-by-step method by tightening the buckle, an improved ratchet belt for sports, comprising: 
 a concave and convex shaped ankle in which a slope surface slanted similarly to a slanted surface of the ratchet belt and a roughly upright surface are repeatedly formed, wherein said ankle is press-formed and insert-injected, and one side of the slope surface is inwardly bent for thereby forming a certain space, and a hole is formed in a center portion of the same, and the upper and lower surfaces of the ankle communicate each other through the hole, and an injection material is filled in the space of the interior of the bent portion, so that the ankle is stably fixed to the ratchet belt.    
     
     
         5 . In a binder operating as an apparatus in which a ratchet belt having a plurality of teeth formed on an upper surface of the same is engaged to a ratchet type buckle having an engaging protrusion, wherein a slanted surface is formed in one side of teeth of a ratchet belt, and a vertical surface is formed in the other side of the teeth, and a ratchet belt is not escaped from a buckle in such a manner that an engaging protrusion is caught by the vertical surface, and the length of the ratchet belt is adjusted in a step-by-step method by tightening the buckle, an improved ratchet belt for sports, comprising: 
 an abrasion prevention part in which a slope surface and upright surface having a construction similar to the slanted surface and a vertical surface, respectively, are repeatedly formed on an upper surface, and the slope surface and the upright surface are engaged with the engaging protrusion of the buckle, wherein the abrasion prevention part is provided in one side of the center of the belt.    
     
     
         6 . The belt of  claim 5 , wherein said abrasion prevention part is insert-injected for thereby forming a ratchet belt, and a plurality of engaging grooves are formed on a slope surface of the abrasion prevention part, and an engaging rod is integrally formed with the ratchet belt at a portion corresponding to the engaging groove, and the engaging rod is engaged with the engaging groove.  
     
     
         7 . The belt of  claim 5 , wherein an engaging steps are provided at a front end and rear end of the abrasion prevention part, respectively, so that the abrasion prevention part is inserted to the ratchet belt.  
     
     
         8 . The belt of  claim 5 , wherein said ratchet belt is formed of a polyurethane material, and said abrasion prevention part is formed of plastic such as polypropylene.  
     
     
         9 . The belt of  claim 2 , wherein said ratchet belt is injected with a polyurethane material, and the slope surface is inwardly curved, so that the polyurethane is stacked thickly on an upper surface of the ankle.  
     
     
         10 . The belt of  claim 6 , wherein an engaging steps are provided at a front end and rear end of the abrasion prevention part, respectively, so that the abrasion prevention part is inserted to the ratchet belt.  
     
     
         11 . The belt of  claim 6 , wherein said ratchet belt is formed of a polyurethane material, and said abrasion prevention part is formed of plastic such as polypropylene.
