  • Link assembly and a bracelet with such an assembly
    Patent number: 9066563
    Abstract: A link assembly has a first link with an inner major surface and an opposite outer major surface, and a second link releasably engageable with the first link. The first link has two locking pins and two control pins, movable simultaneously with each other. When the first link engages the second link, the control pins move between locking and unlocked positions. When the control pins are in the locking positions, part of each locking pin is received within a respective hole of the second link to prevent disengagement of the first link from the second link. When the control pins are in the unlocked positions, the locking pins are clear of the holes to disengage the first link from the second link. Each control pin extends through a respective opening of the first link inner major surface. A spring biases the locking pins away from each other.
