Abstract (en)
[origin: US2004154633A1] A hair holding device and spring concealment mechanism including a pair of opposed, hingedly connected body members adapted to pivot about a hinge axis between closed and open positions. A torsion biasing spring biases the device into a predetermined position. The spring is concealed in multiple casings, which are unattached to either body member of the hair holding device. The casings do not bear any torque exerted by the spring and do not encase the entireties of the spring's first and second projecting arms. Consequently, they can be made relatively thin-walled and compact to closely conform to the size and shape of the coil portion of the spring. The thin walls and small diameter of the spring casings minimize the extent to which the casings protrude from the hair holding device, thereby improving its aesthetic appeal.
