Abstract
A releasable buckle structure and method in which a curved planar engaging member releasably interlocks with a curved planar receiving member, the engaging member having a U shaped opening defined therein and the receiving member having a complementary U shaped solid portion adapted to engage the U shaped opening with the projecting center portion of the U shaped opening extending through the open center of the U shaped solid portion with the solid portion bearing on the concave side of the curved engaging member, the engaging member including a handle portion which, when angularly displaced, induces the solid portion to ride along the concave curved surface of the engaging member until releasing through the slot defining the bottom of the U shaped opening, both the engaging member and the receiving member including means to engage separate belt ends and, in a preferred embodiment, including a narrowed slot at the bottom of the U shaped opening and a displaced center portion of the U shaped opening to reduce the possibility of inadvertent release during nontension situations between the engaging member and the receiving member.
