[0001] The invention relates to the field of satisfying human needs of life, in particular,
to jewellery pieces and other ornaments for wearing on the body with fixing by piercing.
[0002] A jewellery piece is known containing a decorative element, a piercing pin with removable
end head and connection of the piercing pin with the decorative element (
JP No.2001299414, A44C 7/00, 2001).
[0003] A disadvantage of the known jewellery piece is limited use only on body portions
that are not subject to movement and active deformation, in particular, for decoration
of ears. This disadvantage is conditioned by rigid connection of the piercing pin
with the decorative element.
[0004] A more perfect and the closest analogue to the claimed jewellery piece is a jewellery
piece containing a decorative element, a piercing pin with a removable end head and
a hinged joint of the piercing pin with the decorative element having an male link
and a female link (
GB No.2381183 A44C 15/00, 2003).
[0005] The above jewellery piece, while ensuring freedom of active movement of the corresponding
body portion due to moveable joint of the piercing pin with the decorative element,
allows it to be fixed to different body portions, for example, to eyebrows or stomach.
However, in virtue of design peculiarities of the hinged joint of the piercing pin
with the decorative element, its use entails possible damage of the skin the area
of piercing as a result of pinching between the surfaces of the male link and the
female link.
[0006] The technical result, which can be attained when implementing the invention, consists
in enhanced safety of using the jewellery piece.
[0007] The above technical result is achieved by a jewellery piece containing a decorative
element, a piercing pin with removable end head and a hinged joint of the piercing
pin with the decorative element having a male link and a female link due to the fact
that the male link is mounted on the decorative element, while the female link is
mounted on the piercing pin, wherein the female link in the section of mating with
the piercing pin is made with the external surface of convex shape with a curvilinear
outline having the overall dimensions greater than the overall dimensions of the cross-section
of the piercing pin.
[0008] As well as due to the fact that the female link is provided with a recess having
the overall dimensions less than the overall dimensions of the curvilinear outline
of the external surface.
[0009] The essence of the claimed invention is explained by the drawings wherein Fig.1 gives
the representation of the general view of the jewellery piece, Fig.2 gives the A-A
section, and Fig.3 and Fig.4 give variants of hinged joint.
[0010] The jewellery piece comprises decorative element 1 connected to piercing pin 2 and
to removable end head 3 (e.g., by a thread). The linkage between the decorative element
1 and the piercing pin 2 is provided in the form of a hinged joint formed by the male
link 4 mounted on the decorative element 1 and the female link 5 mounted on the piercing
pin 2 associated with the male link 4, for example, with axle 6 or protrusions 7 fixing
the ears on the conjugated surfaces. The female link 5 in section mating with the
piercing pin 2 is provided with the external surface of convex shape and with a curvilinear
outline 8, having the overall dimensions (e.g., "D") greater than the overall dimensions
(e.g., "d") of the cross-section of the piercing pin 2, and may be provided with a
recess 9 having overall dimensions (e.g., "h" and "b") less than overall dimensions
of the curvilinear outline of the external surface (e.g., "H" and "D", respectively).
[0011] Preventing the injury is ensured by position of the skin portion in the piercing
area between the removable head 3 and the external surface of the convex shape with
the curvilinear outline 6 and by the impossibility of displacement of the above skin
portion to the hinged joint area, wherein comfortable conditions of contacting the
jewellery piece with the skin are predetermined by the shape and sizes of the female
link 5 and mobility required for this, by the sizes of recess 9 that are less that
the overall dimensions of the curvilinear outline of the external surface.
1. A jewellery piece comprising a decorative element, a piercing pin with a removable
end head and a hinged joint of the piercing pin with the decorative element having
a male link and a female link, characterised in that the male link is mounted on the decorative element and the female link is mounted
on the piercing pin, wherein the female link section mating with the piercing pin
is provided with an external surface of convex shape and with a curvilinear outline
having the overall dimensions greater that the overall dimensions of the piercing
pin.
2. The jewellery piece according to claim 1, characterised in that the female link is provided with a recess having the overall dimensions less that
the overall dimensions of the curvilinear outline of the external surface.
