  • Ornamental bracelet
    Publication number: 20080190137
    Abstract: An ornamental arm band having a rigid plate. The rigid plate is fastened to an arm of the wearer by way of a springy band that is rigidly fastened at one of its ends to an end of the plate. The plate has at least one lateral recess in its circumferential edge. The springy band has at its other end a loop-shaped link rigidly attached thereon. When being attached to an arm of the wearer, the springy band with its loop-shaped link is slid partly over the thickness of the plate and will then settle firmly in the recess of the plate because of the bias of the springy band.
