Abstract

A clasp structure that is integrally molded is provided and comprises an actuating lever portion, an upper clasping portion, and a lower clasping portion. The actuating lever portion is arcuate in shape and divided at an apex into an upper actuating portion and a lower actuating portion. The upper actuating portion is provided on its internal wall surface with a lower clasping portion. The lower actuating portion also joins with an upper clasping portion on the internal wall surface. The upper clasping portion attaches at one end to the lower clasping portion and extends obliquely at the other end for a certain length and then forms a horizontal clasping surface. Likewise, the lower clasping portion connects at one end to the upper actuating portion of the actuating lever portion and extends inclinedly downward at the other end for a proper length and then forms a horizontal clasping surface that rests on the horizontal clasping surface of the upper clasping portion.

Claims1

Dependent claims

An integrally molded clasp structure, comprising:

an actuating lever portion having an arcuate contour, said actuating lever portion having an upper actuating portion and a lower actuating portion divided by an apex;
an upper clasping portion extending a predetermined distance from an inner wall surface of said lower actuating portion and spaced from said apex, said upper clasping portion having a distal end formed with a first horizontal clasping surface;
a first rib joining an extended portion of a proximal end of said upper clasping portion to said inner wall surface of said lower actuating portion;
a lower clasping portion extending a predetermined distance from an inner wall surface of said upper actuating portion and spaced from said apex, said lower clasping portion having a distal end formed with a second horizontal clasping surface located in aligned relationship with said first horizontal clasping surface and in contact therewith;
and,
a second rib joining an extended portion of a proximal end of said lower clasping portion to said inner wall surface of said upper actuating portion, wherein said first horizontal portion is reversibly displaced from said second horizontal portion responsive to a deformation of said actuating lever between said upper clasping portion and said lower clasping portion when said upper actuating portion and said lower actuating portion is depressed.
