Method and device for joining jewelry components
In accordance with one or more embodiments of the invention, a method of joining a decorative ornament to an earring base component includes a dapped piece (a meniscus lens shaped piece) of material joined to a threaded tube. An opening in the end of the tube connected to the dapped piece is aligned with a hole in the dapped piece. The support piece is then joined to a decorative ornament. The tube is threaded and receives a threaded rod-like base stud. The threaded base stud passes through the hole in the dapped piece and reaches the threads of the tube. The threaded tube provides alignment and increased support between the base stud and the decorative ornament.

1. Field of Invention
The present invention generally relates to methods and devices for joining jewelry components. More specifically, the present invention relates to methods and devices for joining a decorative ornament to a threaded rod-like base earring member.
2. Description of Related Art
Many articles of jewelry are made by attaching decorative ornaments to base jewelry components. The base jewelry components provide the method for wearing the article of jewelry. For example, some earrings are created by attaching a decorative bead to the end of a rod-like metallic stud base. This may be accomplished by drilling a channel in the bead, passing one end of the rod-like stud into the channel, and securing the stud within the channel. The earring is worn by passing the other end of the rod-like stud base through a traditional ear piercing.
Alternatively, the decorative ornament may be a gem basket holding a gem or stone. The side of the gem basket opposite the stone face may have a flat disc with a threaded hole for receiving a threaded rod-like metallic stud base. Because the cross-sectional diameter of the rod-like stud base is often small and the thickness of the gem basket disc is very thin, the contact area of the threaded connection is very small. The small contact area makes it difficult to maintain the desired alignment between the gem basket and the stud base, as the gem basket will tend to pivot or wobble. This design may also concentrate stress on the small contact area, which could result in breakage of the earring and loss of the decorative element.
BRIEF SUMMARY OF EMBODIMENTS OF THE INVENTIONIn accordance with one or more embodiments of the invention, a method for joining jewelry components includes attaching a threaded tube member to a support piece. The support piece is then joined to a jewelry component. Finally, the support piece/jewelry component assembly is threaded onto a threaded rod-like jewelry base.
In accordance with one embodiment of the invention, a method of joining a decorative ornament to an earring base component includes a dapped piece (a meniscus lens shaped piece) of material joined to a threaded tube. An opening in the end of the tube connected to the dapped piece is aligned with a hole in the dapped piece. The tube is threaded and receives a threaded rod-like base stud. The threaded base stud passes through the hole in the dapped piece and reaches the threads of the tube. The threaded tube provides alignment and increased support between the base stud and the decorative ornament.
In this embodiment, the dapped piece is a meniscus lens shaped piece, which has a hole in the center of the piece. The longitudinal axis of the tube extends substantially normal to a plane tangent to the center point of the curved face of the dapped piece. The end of the tube connected to the dapped piece does not extend past the convex side of the dapped piece. The other end of the tube extends from the concave side of the dapped piece. These and other features will become readily apparent from the following detailed description wherein embodiments of the invention are shown and described by way of illustration.
BRIEF DESCRIPTION OF THE DRAWINGSFor a more complete understanding of various embodiments of the present invention, reference is now made to the following descriptions taken in connection with the accompanying drawings in which:
The face of the dapped support piece 100 may have any shape. For example,
The dapped support piece 100 has a tangent plane 105, which is tangent to the convex surface 103 at the center point 106 of the convex surface 103. The tube 102 attached to the dapped support piece 100 has a longitudinal axis 107 extending from an attached end 108 to an extended end 109. The tube 102 is connected to the dapped support piece 100 such that the attached end does not extend past the convex surface 103. In addition, the longitudinal axis 107 of the tube 102 is substantially normal to the tangent plane 105.
In another embodiment, shown in
The tube has an inside surface 110 and an inner diameter 111. In one embodiment, the inside surface 110 is threaded to receive a threaded rod-like insert 112. In addition, the inner diameter of the tube 102 is sized to accommodate the rod-like insert 112. The rod-like insert 112 has an outer surface 113, which is also threaded. In this embodiment, the tube threads may extend the entire length of the inside surface 110 or may only cover part of the inside surface 110. After a decorative element is joined to the dapped support piece (described in detail below), the complementary threads allow the attachment device/decorative ornament assembly to be screwed onto the rod-like insert 112.
In an alternate embodiment (not shown), the inside surface 110 may have other releasable mechanisms. For example, the releasable mechanisms may include complementary magnets mounted on the inside surface 110 of the tube 102 and on the outer surface 113 of the rod-like insert 112. As a further example, the releasable mechanism may include a circular channel on the inside surface 110 that mates with a spring-loaded o-ring mechanism mounted on the outer surface 113 of the rod-like insert 112.
In at least one embodiment (as shown in
The embodiment of the attachment device 10a includes a dapped support piece 100a with an opening 101a in the center. The dapped support piece 100a has a meniscus lens shaped cross section and has a convex surface 103a and a concave surface 104a. One end of a tube 102a is attached to the dapped support piece 100a. The tube 102a is centered over the opening 101a such that the longitudinal axis (not shown) of the tube 102a passes through the center of the opening 101a. The tube 102a has an attached end 108a and an extended end 109a. The tube 102a is connected to the dapped support piece 100a such that the attached end 108a does not extend past the convex surface 103a.
In this embodiment, the radius of curvature of the dapped support piece 100a is greater than in the previously described embodiment of
In this embodiment, the greater radius of curvature would allow the attachment device 10a to better accommodate direct attachment to a spherical decorative ornament, such as a pearl (not shown). In this example, the tube 102a would extend into a channel made in the pearl, and the pearl's surface would be bound to the concave surface 104a by an adhesive. In addition, the radius of curvature of the dapped support piece 100a would be selected to substantially conform to the radius of curvature of the outer surface of the pearl.
In this embodiment, the rear of the gem basket 200 fits snuggly against the concave surface of the dapped support piece 201. This arrangement provides ample surface contact between the dapped support piece 201 and the outer surface of the gem basket 200. Thus, the two components may be securely joined as described above. In addition, the outer most edges of the dapped support piece 201 partially wrap around the rear of the gem basket 200. This design facilitates the attachment device 202 being hidden behind the ornamental stone when viewed from the front.
A tube 203 (the hidden cross section of which is shown in dash lines on
As will be realized, the inventions are capable of other and different embodiments and its several details may be capable of modifications in various respects, all without departing from the invention as set out in the appended claims. For example, the decorative ornament need not be mounted in a gem basket, but could be attached directly to the dapped support piece. Accordingly, the drawings and description are to be regarded as illustrative in nature and not in a restrictive or limiting sense with the scope of the application being indicated in the claims.
