Cufflink Technology

A cufflink having first and second segments that are locked together releasably, the first segment comprising a first head, the second segment comprising a second head, the first segment including a first neck region projecting from the first head to a first distal end region, wherein a plunger is mounted for axial movement within and relative to the first neck region, the plunger having a distal end adjacent to which a shoulder stop is provided, the shoulder stop preventing movement of the plunger in a first axial direction when the shoulder stop engages a stop surface defined by the cufflink's first segment.

An adjustable cufflink and shirt cuff combination, comprising:

• a shirt cuff having a set of four cuff holes;
• a cufflink comprising a first head and a second head, wherein the first and second heads are each too large to pass through any one of said four cuff holes, the adjustable cufflink having a separated configuration in which the first and second heads are in a detached state, and wherein the cufflink has a locking mechanism configured to releasably lock the first and second heads in either of two positions, wherein the first and second heads when locked in a first position are closer together than when they are locked in a second position, such that when the heads are locked in the second position the shirt cuff provides more internal clearance space than when the heads are locked in the first position, and wherein when the heads are locked in either position the locking mechanism prevents the heads from moving significantly toward or away from each other.

A cufflink, comprising:

• first and second heads configured to be releasably locked in a conjoint configuration by a mechanical lock mechanism;
• the cufflink including an actuator to selectively lock and unlock the mechanical lock mechanism, the actuator being configured to move between locked and unlocked positions, wherein the first head comprises a raised wall configured to protect the actuator from inadvertent actuation, the actuator being configured to move relative to said raised wall during locking and unlocking of the lock mechanism, the first head bounding a finger clearance space between the raised wall and the actuator.

A decorative cufflink or stud assembly, comprising:

• a cufflink or stud having first and second enlarged heads and a central neck, the first head defining a pocket in which is received a removable decorative insert, the removable decorative insert being retained removably within the pocket by a resilient retention member and defining a decorative face, the resilient retention member being disposed between an interior wall bounding the pocket and an exterior wall of the removable decorative insert, wherein an insert removal access bore extends from the pocket defined by the first head through the central neck and opens through a desired face of the second head, the desired face of the second head and the decorative face of the insert being generally opposed.
