Multi-functional device for styling hair

1. A multi-functional device for styling hair comprising a handgrip, a first and a second arm, and heating means for heating at least one of said first and second arm, wherein:

said first and second arm are arranged side-by-side and parallel to one another and extending substantially along a longitudinal axis, associated with said handgrip at a first end thereof, respectively;

said first arm comprises a first fixed half-arm integral with the handgrip and extending substantially along the longitudinal axis and a first mobile half-arm elastically supported by said first fixed half-arm and extending substantially along the longitudinal axis between a first area of said first arm close to the handgrip and a second area of said first arm remote from the handgrip;

said second arm comprises a second fixed half-arm integral with the handgrip and extending substantially along the longitudinal axis and a second mobile half-arm elastically supported by said second fixed half-arm and extending substantially along the longitudinal axis between a first area of said second arm close to the handgrip and a second area of said second arm remote from the handgrip;

wherein the device also comprises locking/unlocking means for cooperating with said first mobile half-arm to make the first mobile half-arm to selectively take up one from an unlocked condition, in which the elastic movement of the first mobile half-arm with respect to the first fixed half-arm is allowed, and a locked condition, in which the elastic movement of the first mobile half-arm with respect to the first fixed half-arm is prevented at least at said first area of the first arm; and wherein

said locking/unlocking means for cooperating with said second mobile half-arm to make said second mobile half-arm selectively take up one from an unlocked condition, in which the elastic movement of the second mobile half-arm with respect to the second fixed half-arm is allowed, and a locked condition, in which the elastic movement of the second mobile half-arm with respect to the second fixed half-arm is prevented at least at said first area of the second arm.

2. The device according to claim 1 , wherein said locking/unlocking means comprise a mechanical member suitable for being actuated through sliding, rotation or pressure to make at least one of the first mobile half-arm and the second mobile half-arm selectively take up one from said unlocked and locked conditions.

3. The device according to claim 2 , wherein said mechanical member is associated with the handgrip.

4. The device according to claim 2 , wherein said mechanical member is a slider and in that said locking/unlocking means also comprise a first tang integral with at least one of the first mobile half-arm at the first area of the first arm and a second tang integral with the second mobile half-arm at the first area of the second arm, said slider being slidable so as to engage and disengage at least one of said first tang and said second tang.

5. The device according to claim 4 , wherein said slider comprises spaced portions and close portions suitable for engaging and disengaging at least one of said first tang and said second tang, said slider being able to slide in a transversal direction to the longitudinal axis.

6. The device according to claim 5 , wherein that in the locking condition of the elastic movement of at least one of the first and the second mobile half-arm with respect to at least one of the first and the second fixed half-arm, at least one of said first tang and said second tang abut against said close portions of the slider at least at the first area of at least one of the first and second arm.

7. The device according to claim 4 , wherein said slider comprises an actuation portion and a pair of close and parallel arms suitable for engaging and disengaging at least one of said first tang and said second tang, said slider being able to slide in a direction parallel to the longitudinal axis.

8. The device according to claim 7 , wherein in the locking condition of the elastic movement of at least one of the first and second mobile half-arm with respect to at least one of the first and second fixed half-arm, at least one of said first tang and said second tang are clamped into contact between said pair of close and parallel arms at least at the first area of at least one of the first and second arm.

9. The device according to claim 2 , wherein said mechanical member is a ring nut and in that said locking/unlocking means also comprise a first tang integral with the first mobile half-arm at the first area of at least one of the first arm and a second tang integral with the second mobile half-arm at the first area of the second arm, said ring nut being rotatable about the longitudinal axis so as to engage and disengage at least one of said first tang and said second tang.

10. The device according to claim 9 , wherein said ring nut comprises an opening or a shaped protuberance, in which at least one of said first tang and said second tang engage and disengage.

11. The device according to claim 10 , wherein said opening or said shaped protuberance is slot-shaped, at least one of said first tang and said second tang are semi-circular shaped and, in the locking condition of the elastic movement of at least one of the first and second mobile half-arm with respect to at least one of the first and second fixed half-arm, at least one of said first tang and said second tang abut against the narrower walls of the slot shape at least at the first area of at least one of the first and second arm.

12. The device according to claim 1 , wherein said locking/unlocking means also comprise a spacer element suitable for being inserted/disinserted between the first and second mobile half-arms-to keep them slightly spaced apart in the unlocked condition.
