Handcuff coupling assembly

A coupling assembly for coupling a first handcuff bracelet and a second handcuff bracelet together, each bracelet including a locking mechanism for opening and closing the bracelet, the coupling assembly comprising:

• a swivel assembly for permitting angular nation of at least one of the bracelets in a predetermined first rotational direction relative to a longitudinal axis extending through said swivel assembly and the first and second bracelets, said swivel assembly preventing the bracelets from being rotated in a second rotational direction opposite from said first rotational direction;
• said swivel assembly comprising a base hub attached directly or indirectly to the first bracelet;
• a swivel head attached via coupling means to the second bracelet, said swivel head having a head hub rotatably mounted to said base hub;
• a spring having a base hub engaging portion in frictional engagement with said base hub, and ahead hub, engaging portion in frictional engagement with said head hub;
• whereby rotation of said first bracelet in said second direction results in diametric deformation of said spring causing said base hub engaging portion to lockingly engage said base hub, and said head hub engaging portion to lockingly engage said head hub.

A set of handcuffs comprising:

• a first bracelet and a second t, each including a locking mechanism for opening and closing said bracelet;
• and a coupling assembly for coupling said first bracelet and said second bracelet together;
• said coupling assembly including a swivel assembly for permitting angular rotation of at least one of said first bracelet and said second bracelet in a predetermined first rotational direction relative to a longitudinal axis extending through said swivel assembly and said first and second bracelets, said swivel assembly preventing said at least one of said first bracelet and said second bracelet from being rotated in a second rotational direction opposite from said first rotational direction;
• said swivel assembly including a swivel base attached directly or indirectly to said first bracelet;
• a swivel head rotatably mounted to said swivel base and attached via coupling means to said second bracelet;
• a spring, having a swivel base engaging portion in frictional engagement with said swivel base, and a swivel head engaging portion in frictional engagement with said swivel head;
• whereby rotation of said first bracelet in said second direction results in diametric deformation of said spring causing said swivel base engaging portion to lockingly engage said swivel base, and said swivel head engaging portion to lockingly engage said swivel head, thereby preventing further rotation in said second direction while permitting rotation in said first direction.

A set of handcuffs comprising:

• a first bracelet and a second bracelet, each including a locking mechanism for opening and closing said bracelet;
• and a coupling assembly for coupling said first bracelet and said second bracelet together;
• said coupling assembly including a swivel assembly for permitting angular rotation of at least one of said first bracelet and said second bracelet in a predetermined first rotational direction relative to a longitudinal axis extending through said swivel assembly and said first and second bracelets, said swivel assembly preventing said at least one of said first bracelet and said second bracelet from being rotated in a second rotational direction opposite from said first rotational direction;
• said swivel assembly including a base hub attached directly or indirectly to said first bracelet;
• a swivel head attached via coupling means to said second bracelet, said swivel head having a head hub rotatably mounted to said base hub;
• a spring having a base hub engaging portion in frictional engagement with said base hub, and a head hub engaging portion in frictional engagement with said head hub;
• whereby rotation of said first bracelet in said second direction results in diametric clef ion of said spring causing said base hub engaging portion to lockingly engage said base hub, and said head hub engaging portion to lockingly engage said head hub, thereby preventing further rotation in said second direction white permitting rotation in said first direction.
