Definitions

• the invention relates to a hair clip comprising more particularly two shells provided with claws at the front of the clamp and pivoted relative to each other around two hinge hinges extending in the same axial direction at the back of the clamp.
• the two hulls pivot from a closed position where the claws are brought together, or even intersecting, to clamp the hair trapped by the claws and by an inner wall of each shell, to an open position where the claws are spread to release the hair.
• An elastic return means is deformed tending to oppose the pivoting of the two shells in the open position by reminding them in the closed position.
• a hair clip of this type is in particular known from DE-A-29600643 or from WO2005 / 025371.
• the elastic return means is a spring mounted around an axis carried by the two hinges hull and acting on two levers respectively integrated to the two hulls.
• a cover comprising two tabs hinged together and each connected to the lever of each shell by a hinge is provided to conceal the spring, especially in the closed position.
• the cover attached to the lever has a large footprint, especially in the opening position of the hair clip.
• the spring has been replaced by a link in elastomeric material, stretched between the two shells to be concealed by the latter, especially in the closed position.
• US 2004/0226574 discloses a hair clip as indicated above, further comprising a support plate for receiving for example a jewel. It is supported above the two hulls by the two levers of the clamp with which it is taken behind the axial direction of pivoting of the two hulls. When the levers are brought closer together to rotate the two shells from the closed position to the open position, the support plate pivots relative to the levers.
• the object of the invention is to modify a hair clip of the type recalled above, to reduce the bulk due to the presence of the support plate, especially in the open position.
• the invention thus aims at easier handling of the hair clip.

• the elevation of the support plate relative to the axial pivoting direction, in translation backwards, can be adjusted according to the length of the tabs which support it and the position of their grip with the two. hulls, in front of the axial direction.
• the support plate and the two supporting tabs thus form a podium, having a small footprint both when it is lowered relative to the axial direction, the clamp being in the closed position or when it is high relative to this axial direction, the clamp being in the open position.
• the podium support plate can receive a jewel of any size.

• the elevation results from an increase in the distance separating the axial direction A of the support plate, from a distance D1 in the closed position, to a distance D2, greater than D1, in the position d 'opening.
• the direction of this displacement in translation is imposed by the fact that the tabs 19, 21 or 20, 22 extend rearwardly to support the support plate above the two shells, for example by extending between the two rear edges 23,25 of the shells that tighten around these tabs 19,21 or 20,22 when the shells 1, 3 rotate in the open position.
