Rotatable Mechanism for Jewelry and Decorative Accessories

A rotatable mechanism for jewelry and decorative pieces where the a plurality of ball-bearings are used to connect decorative pieces together with a main fixed piece, allowing the easy rotation and spinning of said decorative pieces, as compared to prior art construction for moveable decorative pieces that are directly linked to the main fixed piece, resulting in more friction being present when the spinning/rotation is to happen. Present invention helps to increase the aesthetic value of jewelry or decorative piece when the freedom of rotation/spinning is greatly enhanced.

Description

FIELD AND BACKGROUND OF THE INVENTION

Present invention relates generally to design and construction of rotatable mechanism for jewelry and decorative accessories, especially for enhancing the aesthetic value at time of viewing and presenting the accessories.

Most decorative accessories or jewelry contain no moveable parts. The stones (diamond or other precious stones) usually are set into a seat on a ring, a bracelet, pendant of necklace or other planar or dimensional surface structured accordingly.

The practice commonly available to increase the movement and/or rotation of jewelry or accessories, to enhance the aesthetic display/presentation of the jewelry or diamonds is found in FIG. 5, which shows several moveable decorative pieces (a) and one main fixed piece (b), whereby a few holes are provided on said main fixed piece (b), to allow moveable decorative pieces (a) to rotate about main fixed piece (b).

The prior art rotational mechanism is rather intuitive and not ideal for the purpose of enhancing the aesthetic presentation of jewelry or decorative accessories, because the existence of the friction as a result of direct contact between the decorative pieces (a) and the holes in said main fixed piece (b). The friction limits the extent of flexibility to which decorative pieces (a) may freely rotate around in the holes of main fixed piece (b).

Present invention solves the limited flexibility of the decorative pieced due to the existence of friction by the use of ball-bearing, placed inside the holes of the main fixed piece, for example, so that the rotation of decorative pieced are made more freely by placing the decorative piece within the ball-bearing structure, which in turn is placed inside the holes on the main fixed piece. That way, the friction between the decorative piece(s) and the main fixed piece is greatly reduced, producing better rotation and aesthetic value for jewelry and decorative accessories.

DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate the preferred embodiment of the invention and together with the description, serve to explain the principles of the invention.

A brief description of the drawings is as follows:

FIG. 1 shows a first embodiment of the front overall view of present invention.

FIG. 2 shows the cutout view of a ball-bearing used in present invention.

FIG. 3 shows the cutout view of a combination ball-bearing used in present invention.

FIG. 4 shows the front view of a second embodiment.

FIG. 5 shows the prior art structure of a rotatable mechanism for jewelry or decorative accessories.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 and 2, the rotatable mechanism of present invention contains at least one main fixed piece 1 and one or more moveable decorative pieces 3. A number of holes are formed on the main fixed piece 1. Ball-bearings 2 contain a inner ring 21 and an outer ring 20 and a plurality of roller balls 22 in between inner ring 21 and outer ring 20.

Ball-bearings 2 are set into the holes on said main fixed piece 1, so that decorative pieces 2 are attached to the inner ring 21 of said ball-bearing 2 and the holes on main fixed piece 1 are connected to the outer ring 20 of said ball-bearing 2, allowing the decorative pieces 3 to spin/pivot around freely relative to main fixed piece 1.

Alternatively, said main fixed piece 1 may be attached directly to the inner ring 21 (without holes) and have the decorative pieces 3 attached to the outer ring 20 of said ball-bearing 2, creating a different type of rotational pattern, by the same ball-bearing structure.

The inner ring 21 and its connecting material are preferably made from the same material/process; the outer ring 20 and its connecting material should similarly be made from the same material/process, to simplify the manufacturing/assembly workflow.

FIG. 3 shows a combination ball-bearing of present invention, where an inner concentric ball-bearing 4 is placed within an outer concentric ball-bearing 5, so that an inner ring 41 (of inner concentric ball-bearing 4) is attached to decorative pieces 3 and an outer ring 40 (of inner concentric ball-bearing 4) is connected to inner ring 51 (of outer concentric ball-bearing 5). Roller balls 42 allow the free rotation of inner ring 41 relative to outer ring 40. Roller balls 52 allow the free rotation of inner ring 51 relative to outer ring 50.

Outer ring 40 (or inner concentric ball-bearing 4) and inner ring 51 (of outer concentric ball-bearing 5) are connected together by filler material 53.

FIG. 4 shows the cutout view of another embodiment of present invention, where the main fixed piece 1 is separated into two segments by a center ball-bearing 60. A decorative piece 61 is concentrically seated in the inner ring of said ball-bearing 60. That way, the decorative piece 61 is freely moveable within said center ball-bearing 60 and increases the aesthetic value of the jewelry piece.

Each segment of main fixed piece 1 has two holes, towards which a ball-bearing 2 is attached.

The main fixed piece, the decorative piece(s) and the ball-bearing(s) are preferably made from the same material, so as to minimize the loosening, deformation or inflation/deflation due to change in temperature or other external/internal factors.

It is recommended that the main fixed piece, decorative piece(s) and the ball-bearing(s) use the precious metals in the range of gold, silver, platinum or titanium.

The inventive substance of present invention can be applied to rings (on fingers), ear rings, bracelets, decorative articles on clothing or even cell phones, to increase the aesthetic value of said objects.

The alternative embodiment of present invention, as shown in FIG. 4, where the decorative piece 61 can be any precious stone that is set in the center of the center ball-bearing 60 and also allows for other gem stones being interchangeably set in the center position of center ball-bearing 60, creating versatility for users.

Claims

a. A main fixed piece having at least one hole; and,
b. A ball-bearing attached to the inside of each of said hole, said ball-bearing further having a moveable decorative piece attached to a inner pivoting portion of said ball-bearing, so that the decorative piece can turn or spin freely relative to said main fixed piece, due to the use of said ball-bearing.
