Abstract

The disclosure concerns a jewelry mounting apparatus for pendants, bracelets, rings and the like which incorporates a planar mounting frame adapted to rotate about one or more positional axes for the purpose of displaying opposing surfaces of mounted coins, gems, other ornamental objects and the mounting components. An inner mounting frame has an aperture centrally disposed therethrough. The item to be displayed is mounted within the central aperture of the inner mounting frame. A pair of pivot pins depend outwardly from the outer surface of the inner mounting frame, defining a rotational axis about which the inner mounting frame will rotate. An outer planar mounting frame has an aperture disposed therethrough. A plurality of opposed detents are formed in the surface of the outer frame about the aperture. The location and selection of the pivot detents which are used to engage the pivot pins establishes the axis of rotation of the inner mounting frame relative to the outer frame and for the proper orientation of the mounted coin or other object.

Dependent claims

An apparatus for mounting and displaying a circular disk having ornamented obverse and reverse faces in parallel space relation comprising:

(a) a cylindrical first mounting frame having inner and outer surfaces bounded by parallel top and bottom surfaces, the inner surface being adapted to receive and uniformly circumscribe the disk, the top and bottom surfaces of the first mounting frame being in a planar relationship to the obverse and reverse surfaces of the disk;
(b) setting means for coupling the disk to the first mounting frame, said setting means being coupled to the top and bottom surfaces of the first mounting frame at the inner surface thereof;
(c) an intermediate rotation frame having a top and bottom surface and concentric inner and outer cylindrical surfaces, the inner cylindrical surface being adapted to uniformly circumscribe and be equally spaced from the outer surface of the first mounting frame;
(d) a first pivot assembly coupled intermediate said first mounting frame and said intermediate rotation frame comprising:
(i) a pair of pivot pins extending outwardly from the outer surface of the cylindrical first mounting frame in diametric opposition to each other, said pivot pins defining an axis of rotation along the diameter of the cylindrical first mounting frame;
and
(ii) at least two sets of detents formed in the inner cylindrical surface of the intermediate rotation frame, each set consisting of two detents in axial opposition to one another and being adapted to be in forced engagement with the pivot pin of said first pivot assembly to define a unique axis of rotation about which the cylindrical first mounting frame is rotatable;
(e) a second mounting frame having a top and bottom surface and a cylindrical aperture disposed therethrough defining an aperture surface, the axis of the cylindrical aperture being perpendicular to the top and bottom surfaces, the aperture surface being adapted to circumscribe and be spaced from the outer surface of said intermediate rotation frame;
and
(f) a second pivot assembly coupling said second mounting frame and intermediate rotation frame comprising:
(i) a pair of pivot pins extending radially outwardly from the outer cylindrical surface of the intermediate rotation frame in diametric opposition to each other, said pivot pins defining an axis of rotation along the diameter of the intermediate rotation frame;
and
(ii) at least two sets of detents formed in the aperture surface of the second mounting frame, each set consisting of two detents in axial opposition to one another and being adapted to be in forced engagement with said pivot pins to define a unique axis of rotation about which the intermediate rotation frame is rotatable.

An apparatus for mounting and displaying the ornamented obverse and reverse surfaces of a planar work comprising:

(a) a first mounting frame comprising a planar member having a parallel top and bottom surfaces and an aperture disposed therethrough between the top and bottom surfaces and being adapted to receive and circumscribe the planar work;
(b) setting means for coupling the planar work to the first mounting frame, said setting means being coupled to the top and bottom surfaces of the first mounting frame at the aperture disposed therethrough whereby the planar work is coupled to and is circumscribed within the aperture in the first mounting frame;
