Articulated open ring

A body part worn ring, comprising:

• a first rigid bent arm having a first arm first end and a first arm second end;
• a second rigid bent arm having a second arm first end and a second arm second end;
• an articulation connecting said first arm first end and said second arm first end and to provide a pivot connection between said first arm first end and said second arm first end;
• a head part arranged in a locked position adjacent to said articulation and in contact with each of said first rigid bent arm and said second rigid bent arm preventing pivoting motion between said first rigid bent arm and said second rigid bent arm, said head part being movable to an unlocked position not in contact with one of said first rigid bent arm and said second rigid bent arm allowing pivoting motion between said first rigid bent arm and said second rigid bent arm;
• a first connecting means for securing the head part relative to said first and second arms in said locked position;
• and
• a second connecting means for securing said head part relative to said first and second arms in said locked position and releasing said head part relative to at least one of said first and second arms in an unlocked position, whereby upon pivoting motion between said first rigid bent arm and said second rigid bent arm said first arm second end and said second arm second end are separated, such that the ring can be slipped onto or off the wearer's body part through a gap that separates said first arm second end and may be pivoted back to a locked position.

A ring, of the type intended to be arranged on a body part of a wearer, the ring comprising:

• two rigid bent arms;
• an articulation connecting said arms, said arms being mobile facing each other at a first of two ends;
• a head part arranged in proximity to the articulation and arranged so as to be able to occupy a first position, called the locking position, and a second position called the unlocking position;
• and
• first and second connecting means for securing the head part respectively to the first and second arms, said first and second connecting means both being locked when the head part is in the locked position and at least the first of said connecting means being disengaged when the head part is in the unlocked position, the arms being arranged to occupy:
• an open position in which the arms second ends are separated, such that the ring can be slipped onto or off the wearer's body part through a gap that separates the arms second ends, and
• a closed position in which the gap is reduced, the arms surrounding the wearer's body part, the first connecting means including first and second parts rigidly associated respectively with the first arm and with the head part, wherein said articulation includes at least a binge secured to at least one a said arms and which defines a first pivoting axis, said hinge being masked by said head part when the head part is in the locked position and exposed by said head part in the unlocked position allowing said arms to pivot about the pivot axis.
