View Patent ↗An earring includes a pointed pin adapted to be reversibly inserted into a receiving housing provided with a means for guiding the pin, the receiving housing also including at least one seal. The guide means is formed by a concavity whose bottom is open, a diameter of the open base of the concavity being at least 30% greater than an outer diameter of the receiving housing, a depth of the concavity being equal to half a length of the receiving housing. The pin is provided with at least two circular grooves suitable for temporarily receiving two annular seals when the pin is inserted into the slot of the two annular seals.
1. An earring ( 1 ), comprising a male part ( 2 ) configured as a pointed pin, one end ( 4 ) of which opposite a pointed end ( 6 ) is provided with a decorative element, the pointed end ( 6 ) being adapted for reversible insertion into a receiving housing formed in a female part ( 3 ; 30 ) of the earring ( 1 ), the receiving housing ( 3 ; 30 ) being cylindrical and provided, at an opening, with a means ( 10 ; 100 ) for guiding the pointed pin ( 2 ) into the receiving housing ( 3 ; 30 ) when the pointed pin ( 2 ) is inserted into the receiving housing, the receiving housing ( 3 ; 30 ) also comprising at least one seal ( 15 ), a guiding means being formed by a concavity ( 10 ; 100 ) at one end of the cylindrical receiving housing ( 3 ; 30 ), a base ( 12 ) of which is open and defines an access opening to the receiving housing, a diameter (D) of the base ( 12 ) of the concavity ( 10 ; 100 ) being at least 30% greater than an external diameter of the receiving housing ( 3 ; 30 ), a depth (P) of the concavity ( 10 ; 100 ) being equal to half a length (L) of the receiving housing ( 3 ; 30 ) and in that at least part ( 7 ) of the pointed pin ( 2 ) is provided with at least two circular grooves ( 16 ), parallel and oriented perpendicularly to a main longitudinal axis (AA) of the pointed pin ( 2 ), said two circular grooves ( 16 ) being adapted to temporarily receive two annular seals ( 15 ) when the pointed pin ( 2 ) is inserted into a slot of the two annular seals ( 15 ) themselves inserted in the receiving housing ( 3 ; 30 ), wherein the concavity ( 10 , 100 ) is parabola-shaped, or, at least inside, with the form of a double-sloped cone, and in that the receiving housing ( 30 ) is equipped with a plate ( 19 ) perforated at a center of the plate ( 19 ) and arranged parallel to a bottom of the receiving housing, said plate ( 19 ) ensuring separation between the two annular seals ( 15 ) arranged in the receiving housing ( 30 ) while allowing the pointed pin ( 2 ) to pass freely into the receiving housing ( 30 ).
2. The earring according to claim 1 , wherein the pointed end ( 6 ) of the pointed pin ( 2 ) is instead configured as a blunt-tipped bullet shape.
3. The earring according to claim 2 , wherein the bottom ( 14 ) of the receiving housing ( 3 ; 30 ) of the pointed pin ( 2 ) is provided with an orifice ( 13 ) for passage of the bullet-shaped end ( 6 ) of the pointed pin ( 2 ) when the latter is in a holding position in the receiving housing ( 3 ; 30 ).
4. The earring according to claim 3 , wherein the bottom ( 14 ) of the receiving housing provided with the orifice ( 13 ) is removable.
5. The earring according to claim 1 , wherein the two annular seals ( 15 ) are provided with a flat outer face ( 20 ) adapted to bear against an inner face of the receiving housing ( 30 ).
