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.

L'invention concerne un dispositif de maintien des cheveux et un mécanisme de dissimulation de ressort, comprenant une paire d'éléments structurels opposés reliés par une charnière, conçus pour pivoter autour d'un axe de charnière entre des positions fermée et ouverte. Un ressort de sollicitation en torsion sollicite le dispositif pour le mettre dans une position prédéterminée. Le ressort est dissimulé dans des logements multiples qui ne sont pas attachés à un des éléments structurels du dispositif de maintien de cheveux. Les logements ne subissent aucun couple exercé par le ressort et ne logent pas l'intégralité des premier et second bras saillants du ressort. Par conséquent, ils peuvent présenter des parois relativement minces, ils peuvent être relativement compacts et épouser ainsi étroitement les formes de la partie en spirale du ressort. Les parois minces et le faible diamètre des logements du ressort permettent de l'ampleur de la saillie des logements par rapport au dispositif de maintien des cheveux, ce qui améliore ainsi l'esthétique du dispositif.
