s earlobe , the possibility of an allergic reaction occurring from the contact of post 51 to the interior of the pierced portion of the wearer &# 39 ; s earlobe , is minimized . in this regard , the use of the term &# 34 ; non - allergenic material &# 34 ; throughout this specification and appended claims means a material such as gold , platinum , or any other material having the requisite non - allergenic properties and strength characteristics inherent in the manufature and use of an earring . although 14 karat gold is preferred , other gold alloys , such as 18 karat gold , could also be utilized , as would be readily known to one of ordinary skill in the art . decorative end member 52 is also preferably manufactured from a non - allergenic material , and is disposed at the first end 56 of post 51 in a plane which is substantially perpendicular to the longitudinal axis of post 51 . decorative end member 52 may be secured to the first end of post 51 in any suitable manner such as by being formed integral with post 51 , being soldered to post 51 , or threadedly received upon post 51 . ornamentation adapter member 53 my have any desired ornamentation 54 associated therewith . in this regard , ornamentation 54 , which is shown in phantom lines to indicate that the shape of the ornamentation could be any shape desired , is preferably manufactured from an inexpensive plastic or metallic material . ornamentation 54 may be formed integral with ornamentation adapter member 53 , or could be releaseably secured thereto in any convenient and conventional manner , such as by a velcro ® tab , double - sided tape , or by small screws . preferably , ornamentation 54 is manufactured of an inexpensive plastic or metallic material , and is formed integral with ornamentation adapter member 53 , such as by glue or solder . as will be hereinafter described in greater detail , it is not necessary to manufacture ornamentation adapter member 53 from an expensive non - allergenic material , such as gold . ornamentation adapter member 53 , as seen in fig2 is disposed adjacent the decorative end member 52 , and ornamentation adapter member 53 includes means for releaseably securing 58 the ornamentation adapter member 53 to the decorative end member 52 . the releaseable securing means 58 preferably includes a cavity 59 disposed within the ornamentation adapter member 53 for receiving the decorative end member 52 therein . releaseable securing means 58 also preferably includes means for engaging 60 a portion of the post 51 disposed adjacent the decorative end member 52 , as will be hereinafter described in greater detail . still with reference to fig1 and 2 , the means for locking 55 the post 51 and ornamentation adapter member 53 having the decorative end member 52 received therein , is disposed adjacent the second end 57 of post 51 and may likewise be manufactured from a non - allergenic material . preferably , locking means 55 comprises a conventional earring post clip 61 . it should thus be understood that after desired ornamentation adapter member 53 , having ornamentation 54 associated therewith is releaseably secured via releaseable securing means 58 to decorative end member 52 , post 51 is inserted through the pierced portion of the wearer &# 39 ; s earlobe , and a clutch or locking means 55 is engaged to secure ornamentation adapter member 53 , with decorative end member 52 received within cavity 59 , and post 51 to the wearer &# 39 ; s earlobe , in a conventional manner . still with reference to fig1 and 2 , as substantially planar decorative shield member 62 , manufactured from a non - allergenic material , may be releaseably disposed upon the post 51 adjacent the decorative end member 52 and in an abutting relationship with the ornamentation adapter member 53 . when the decorative shield member 62 is utilized , as previously described , the components of earring 50 , or post 51 , locking means 55 , and decorative shield member 62 , which contact the wearer &# 39 ; s earlobe , are manufactured of a non - allergenic material , whereby the likelihood of an allergic reaction occurring to the wearer of the earring is minimized . if decorative shield member is not utilized as shown and described in connection with fig2 some individuals may still be able to wear earring 50 and not suffer an allergic reaction , even though the ornamentation adapter member 53 is not manufactured from a non - allergenic material , insofar as the interior of the pierced portion of the wearer &# 39 ; s earlobe is only in contact with the non - allergenic post 51 . for those individuals who might still suffer an allergic reaction because of contact of their earlobe with the exterior of the ornamentation adapter member 53 , the surface of ornamentation adapter member 53 , which contacts the wearer &# 39 ; s earlobe , could be provided with a thin plating of non - allergenic material , or preferably , such an individual would always utilize decorative shield member 62 when wearing an ornmentation adapter member 53 which is manufactured from a non - allergenic material . it should be also readily apparent to one of ordinary skill in the art that an individual could wear as an earring only decorative end member 52 , with post 51 and locking means 55 , or only decorative end member 52 , decorative shield member 62 , post 51 and locking means 55 . post 51 may be provided with a means for bracing 63 the decorative shield member 62 to maintain the abutting relationship between the decorative shield member 62 and the ornamentation adapter member 53 . the bracing means 63 may comprise at least one projection 64 extending outwardly from post 51 adjacent the decorative end member 52 , and the decorative shield member 62 may include an opening 65 therein to permit passage of the decorative shield member 62 over the post 51 and the at least one projection 64 . preferably , the at least one projection 64 comprises two outwardly extending pins 66 radially disposed upon the post 51 approximately 180 ° apart . the decorative shield member 62 may then have a first opening 67 which corresponds to the outer cross - sectional configuration of the post 51 and two openings 68 disposed adjacent the first opening 67 and radially spaced from one another approximately 180 °. these openings 68 thus correspond to the outer cross - sectional configuration of the two outwardly extending pins 64 , whereby decorative shield member 62 may be readily passed over post 51 with pins 66 and openings 68 being disposed in a mating relationship , whereby decorative shield member 62 may be placed in an abutting relationship with the ornamentation adapter member 63 , as shown in fig2 . after decorative shield member 52 is in an abutting relationship with ornamentation adapter member 53 , decorative shield member 62 may be rotated whereby pins 66 bear against the back surface 69 of decorative shield member 62 , whereby not only is ornamentation adapter member 53 and decorative shield member 62 securely retained in an abutting relationship , but such abutting and locked relationship permits the easy assembly and insertion of earring 50 through the wearer &# 39 ; s earlobe . it should of course be understood by one of ordinary skill in the art that other suitable forms of bracing means 63 could be utilized . as seen in fig1 ornamentation adapter member 53 may have an opening 70 formed therein which permits entry of the decorative end member 52 into cavity 59 . engagement means 60 may comprise an elongate slot or passageway 71 having first and second ends 72 , 73 , with the first end 72 disposed adjacent the opening 70 and in communication therewith . as seen in fig1 the passageway 71 may have a configuration which corresponds to the outer cross - sectional configuration of post 51 , whereby the decorative end member 52 may be first inserted through the opening 70 and into the cavity 59 , and then the post 51 is moved into the first end 72 of passageway 71 until the post 51 engages the second end 73 of passageway 71 , which places the decorative end member 52 and ornamentation adapter member 53 in an abutting relationship , as shown in fig2 . opening 70 and ornamentation adapter member 53 can be of any configuration , whereby decorative end member 52 may pass through opening 70 into cavity 59 of ornamentation adapter member 53 . thus , if the configuration of decorative end member 52 is circular , such as is shown in fig1 opening 70 could have a circular configuration which corresponds in size to the configuration of decorative end member 52 . preferably , as is shown in fig1 the opening 70 in ornamentation adapter member 53 has a configuration which is smaller than the outer configuraton of the decorative end member 52 . by use of the term &# 34 ; smaller &# 34 ; is meant that were decorative end member 52 to be moved toward ornamentation adapter member 53 in a direction which is perpendicular to ornamentation adapter member 53 , decorative end member 52 would not be able to pass through opening 70 . thus , as shown in fig1 the width of opening 70 , as shown by arrows w , is at least as great as the width of decorative end member 52 , but the height , as shown by arrows h , is not as great as the height of decorative end member 52 , whereby the ornamentation adapter member must be tilted with respect to the decorative end member 52 in order for decorative end member 52 to be inserted into the cavity 59 . thus , upon tilting ornamentation adapter member 53 , decorative end member 52 may be first inserted through opening 70 into cavity 59 , and upon post 51 entering the first end 72 of passageway 71 , the remaining portion of decorative end member 52 may pass through opening 70 , as post 51 is moved upwardly to abut against the second end 73 of passageway 71 . accordingly , the rear surface 74 of decorative end member 52 is in abutting relationship with the interior surface 75 of ornamentation adapter member 53 , to firmly and fixedly support ornamentation adapter member 53 with respect to decorative end member 52 and post 51 , to minimize ornamentation adapter member 53 from being accidentally dislodged from decorative end member 52 . in this regard , when decorative shield member 62 is also utilized , and is placed in an abutting relationship with ornamentation adapter member 53 as shown in fig2 the chances for accidental movement of ornamentation adapter member 53 with respect to decorative end member 52 is further minimized . it should be readily apparent to one of ordinary skill in the art that the cross - sectional configurations for decorative shield member 62 , post 51 , decorative end member 52 , and ornamentation adapter member 53 could be any desired geometric shape . the only restrictions on such configurations are that post 51 must be able to pass through opening 67 of decorative shield member 62 and decorative end member 52 must be able to pass through opening 70 and enter cavity 59 within ornamentation adapter member 53 . with reference now to fig3 and 4 , another convertible pierced - earlobe earring 50 &# 39 ;, in accordance with the present invention is illustrated . like reference numerals have been utilized in fig3 and 4 to designate components of earring 50 &# 39 ; which have the same structure and characteristics as those previously described in connection with fig1 and 2 . earring 50 &# 39 ; differs from earring 50 of fig1 and 2 , in that an ornamentation member 80 is disposed between decorative shield member 62 and decorative end member 52 , in a manner which is similar to the disposition of a portion of ornamentation adapter member 53 , between decorative end member 52 and decorative shield member 62 . ornamentation member 80 , as seen in fig3 and 4 , has a support member 81 removeably disposed upon the post 51 adjacent the decorative end member 52 , and has downwardly , extending ornamentation 82 secured to the support member 81 . ornamentation 82 may be of any desired configuration , but is preferably of the type that is known as &# 34 ; dangle &# 34 ; type of earring construction . with use of decorative shield member 62 , ornamentation member 80 does not contact the wearer &# 39 ; s earlobe , whereby ornamentation member 80 may be manufactured of any inexpensive metallic or plastic material . the likelihood of the wearer suffering an allergic reaction has been minimized through use of the non - allergenic components of earring 50 &# 39 ; as previously described in connection with earring 50 . decorative shield member 62 , post 51 , decorative end member 52 and ornamentation member 80 might have any suitable desired cross - sectional configuration . the only constraints on the choice of the cross - sectional configuration of the components of earring 50 &# 39 ; is that post 51 must be able to pass through opening 65 of decorative shield member 62 , and post 51 must be able to pass through the support member 81 of ornamentation member 80 . it is to be understood that the invention is not limited to the exact details of construction , operation , exact materials or embodiment shown and described , as obvious modifications and equivalents will be apparent to one skilled in the art ; for example , additional decorative shield members of different sizes could be utilized at the same time . accordingly , the invention is therefore to be limited only by the scope of the appended claims
a convertible pierced - earlobe earring provides for the use of a multitude of different , inexpensive ornamentations , while permitting the use of non - allergenic materials for the components of the earring which contact the wearer &# 39 ; s earlobe . an ornamentation adapter member may be readily interchanged to permit various ornamentations to be utilized with a single gold post earring .
