US Patent 7874049 Buckle

Disclosed is a buckle attached to a belt or a strap which is connected to a rucksack, a bag, clothing, and a helmet, etc. so as to connect the belt or the strap. The buckle includes: a male member including a body and first latching means; and a female member which includes a body and second latching means rotatably coupled to the body so as to latch on the first latching means, for removably engaging with the male member. The buckle constructed as described above has a simple structure. Thus, it is possible to reduce the manufacturing cost of the buckle. Furthermore, there is an advantage in that the second latching means of the female member may be softly pushed, so as to easily release the male member from the female member.
