Strap latch

Abstract

A strap latch includes a female buckle, and a male buckle detachably snapped onto the female buckle. Each of the male buckle and the female buckle is provided with a clamping member for clamping a fabric strap. The clamping member has two clamping pieces each having an inner face formed with a plurality of protruding engaging blocks engaged with the respective fabric strap. Thus, each of the engaging blocks has a planar contact with the respective fabric strap to increase the contact area between each of the engaging blocks and the respective fabric strap, so that each of the engaging blocks is engaged with the respective fabric strap closely.

1 . A strap latch, comprising a female buckle, and a male buckle detachably snapped onto the female buckle, wherein: 
 each of the male buckle and the female buckle is provided with a clamping member for clamping a fabric strap;    the clamping member has two clamping pieces each having an inner face formed with a plurality of protruding engaging blocks engaged with the respective fabric strap and an outer face formed with a locking block locked in the locking hole and of each of the male buckle and the female buckle.    
   
   
       2 . The strap latch in accordance with  claim 1 , wherein each of the engaging blocks has a planar contact with the respective fabric strap to increase a contact area between each of the engaging blocks and the respective fabric strap, so that each of the engaging blocks is engaged with the respective fabric strap closely.  
   
   
       3 . The strap latch in accordance with  claim 1 , wherein each of the engaging blocks has an oblique tapered shape to engage the respective fabric strap closely.  
   
   
       4 . The strap latch in accordance with  claim 1 , wherein each of the engaging blocks has two sides each formed with a ramp rested on the respective fabric strap to increase the contact area between each of the engaging blocks and the respective fabric strap.  
   
   
       5 . The strap latch in accordance with  claim 1 , wherein the two clamping pieces of the clamping member have a connection formed with a slit so that the clamping member is made flexible and the two clamping pieces of the clamping member are movable toward each other.  
   
   
       6 . The strap latch in accordance with  claim 5 , wherein the locking block of each of the two clamping pieces of the clamping member has a tapered shape and a thickness gradually increased from the connection to a distal end of each of the two clamping pieces.  
   
   
       7 . The strap latch in accordance with  claim 1 , wherein each of the two clamping pieces of the clamping member is formed with a plurality of substantially rectangular engaging holes for engaging the respective fabric strap.  
   
   
       8 . The strap latch in accordance with  claim 7 , wherein the engaging holes of one of the two clamping pieces are aligned with the engaging blocks of the other one of the two clamping pieces so that the engaging blocks and the respective engaging holes co-operate to engage the respective fabric strap.  
   
   
       9 . The strap latch in accordance with  claim 7 , wherein the engaging holes of the two clamping pieces of the clamping member are arranged in a staggered manner.  
   
   
       10 . The strap latch in accordance with  claim 1 , wherein the engaging blocks of the two clamping pieces of the clamping member are arranged in a staggered manner.  
   
   
       11 . The strap latch in accordance with  claim 1 , wherein each of the engaging blocks has a substantially rectangular root portion extended from the inner face of each of the two clamping pieces of the clamping member.
