Howard Cheng - Chicago IL 60608

International Classification:

A44B 1100

US Classification:

24647, 24537, 24645

Abstract:

A jewelry clasp used to secure a piece of jewelry to an individual. The clasp includes a female part attached to one end of the piece of jewelry that has a latch pivotally mounted within a recess on the female part. The latch includes a hook at one end having an outer sloping surface. The clasp also includes a male part attached to the opposite end of the piece of jewelry and including a loop. The loop has a crossbar at its outer end which has an outer sloping wall. The outer wall of the crossbar and the outer surface of the hooks slope in similar directions, such that when the crossbar is pressed against the hook, the hook slides upwardly with respect to the crossbar, until the hook passes over the crossbar and drops through the center of the loop to engage the loop. The clasp also includes a sleeve slidably mounted to the male part that selectively covers the engagement of the male part and female part when the clasp is in the engaged position.

International Classification:

A44C017/02

US Classification:

63 291, 63 21, 63 23

Abstract:

A closed loop connector for jewelry includes a first U-shaped connector half formed from a flat strip of metal and a second U-shaped connector half formed from a piece of metal wire. The connector half formed form the flat strip of metal includes tubular cylindrical end portions. The second U-shaped connector half is formed from a piece of metal wire having headed end portions, one of the headed end portions being captured in one of the cylindrical end portions and held therein for rotation on the axis thereof. The other of the headed end portions is captured in the other cylindrical end portion by lateral movement through an open slot in response to resilient deflection of the edges of the end portion forming the slot. The metal strips forming one of the U-shaped connector halves may be formed from stampings of different configurations.
