Strap latch
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.

BRIEF DESCRIPTION OF THE DRAWINGS
Referring to the drawings and initially to
Referring to
The clamping member 53 has two clamping pieces 532 each having an inner face formed with a plurality of protruding engaging blocks 533 engaged with the respective fabric strap 6 and an outer face formed with a locking block 535 locked in the locking hole 511 and 521 of each of the male buckle 51 and the female buckle 52. The two clamping pieces 532 of the clamping member 53 have a connection formed with a slit 531 so that the clamping member 53 is made flexible and the two clamping pieces 532 of the clamping member 53 are movable toward each other. The locking block 535 of each of the two clamping pieces 532 of the clamping member 53 has a tapered shape and a thickness gradually increased from the connection to a distal end of each of the two clamping pieces 532.
Each of the two clamping pieces 532 of the clamping member 53 is formed with a plurality of substantially rectangular engaging holes 534 for engaging the respective fabric strap 6. The engaging holes 534 of one of the two clamping pieces 532 are aligned with the engaging blocks 533 of the other one of the two clamping pieces 532 so that the engaging blocks 533 and the respective engaging holes 534 co-operate to engage the respective fabric strap 6. The engaging blocks 533 and the respective engaging holes 534 of the two clamping pieces 532 of the clamping member 53 are arranged in a staggered manner.
Each of the engaging blocks 533 has a planar contact with the respective fabric strap 6 to increase the contact area between each of the engaging blocks 533 and the respective fabric strap 6, so that each of the engaging blocks 533 is engaged with the respective fabric strap 6 closely. Each of the engaging blocks 533 has an oblique tapered shape to engage the respective fabric strap 6 closely and has two sides each formed with a ramp 5330 rested on the respective fabric strap 6 to increase the contact area between each of the engaging blocks 533 and the respective fabric strap 6. Each of the engaging blocks 533 has a substantially rectangular root portion 5332 extended from the inner face of each of the two clamping pieces 532 of the clamping member 53.
Accordingly, each of the engaging blocks 533 has a planar contact with the respective fabric strap 6 to increase the contact area between each of the engaging blocks 533 and the respective fabric strap 6, so that each of the engaging blocks 533 is engaged with the respective fabric strap 6 closely. In addition, each of the engaging blocks 533 has an oblique tapered shape and has two sides each formed with a ramp 5330 rested on the respective fabric strap 6 to increase the contact area between each of the engaging blocks 533 and the respective fabric strap 6 so as to engage the respective fabric strap 6 closely. Further, the engaging blocks 533 and the respective engaging holes 534 co-operate to engage the respective fabric strap 6 closely.
Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
