Patent Description
PRIOR APPLICATIONS
[0001] This application claims the benefit of U.S. Provisional
Patent Application No. 60/720,019 filed Sep. 24, 2005.
FIELD OF THE INVENTION
[0002] The present invention generally relates to jewelry connectors,
and more particularly relates to a jewelry post connector that cannot
be directly disconnected by hand but which requires a separate actuator
for removal.
BACKGROUND OF THE INVENTION
[0003] Some connectors for securing jewelry posts, such as the
posts of earrings for pierced ears, are known in the art. Many jewelry-post
connectors (also called clutches, clasps, retaining devices, etc.)
rely on resilient members biased against the post, perhaps in grooves
in the post adapted to that purpose, in order to secure the connector
onto the post. The known connectors are attached and detached by
hand, limiting the strength of the resilient members to that strength
that can be easily compressed with the fingers. As a result, and
as recognized by the present inventors, earrings are sometimes lost
because the connector's weak connection to the post fails. Another
disadvantage of the existing connectors is that a clever thief may
deftly remove the finger-operated connector.
[0004] Accordingly, it is desirable to provide a jewelry-post connector
that cannot be removed by hand. In addition, it is desirable to
provide a customized actuator for removing such connectors. Further,
it is desirable to provide various approaches to actuating removal
of such connectors. Furthermore, other desirable features and characteristics
of the present invention will become apparent from the subsequent
detailed description of the invention and the appended claims, taken
in conjunction with the accompanying drawings and this background
of the invention.
BRIEF SUMMARY OF THE INVENTION
[0005] A system is provided for removably securing jewelry to a
portion of the human body or to clothing by means of a jewelry post
connector with a required complimentary separate actuator for removal
of the connector. The system comprises a connector having an engaging
member operable in a first position to limit the motion of a jewelry
post and operable in a second position to release a jewelry post,
a web configured to prevent manual access to the engaging member,
and an actuator operable to move the engaging members from their
first position to their second position.

DETAILED DESCRIPTION OF THE INVENTION
[0016] The following detailed description of the invention is merely
exemplary in nature and is not intended to limit the invention or
the application and uses of the invention. Furthermore, there is
no intention to be bound by any theory presented in the preceding
background of the invention or the following detailed description
of the drawings.
[0017] "Jewelry," or "article of jewelry,"
as used and defined herein, means any item of adornment attachable
to the human body (as by piercing, for non-limiting example) or
to articles of apparel, including hats and shoes, by means of a
jewelry post penetrating though a new or prepared hole in the material
to which the jewelry is to be attached and securable by a jewelry
post connector. For example and without limitation, jewelry would
include earrings, pierced-body adornments, label pins, broaches,
hat decorations, military uniform insignia, badges, and campaign
ribbons.
[0018] FIG. 1A is a sectional elevation view illustrating an exemplary
jewelry post connector 100 (hereinafter "connector") in
an intermediate position while being installed, according to the
present invention. Jewelry post 106 is shown connected to an article
of jewelry 114 and is further shown pushed through a penetration
in material 116, such as an earlobe, a jacket, or other jewelry-supporting
material 116. The material 116 may have one or more penetrations
adapted to receive one or more jewelry posts 106. A single article
of jewelry 114 may have multiple jewelry posts 106 and may required
multiple connectors 100 or a single connector 100 sized, shaped,
and arranged to connect to multiple jewelry posts 106. Jewelry post
106 has an indentation such as a socket or circumferential groove
103 for receiving an end piece 108 of engaging member 104, as shown.
Preferably, the indentation is a groove 103, as shown, obviating
control of the rotational orientation of the connector 100 in relationship
to the jewelry post 106. Those skilled in the art, upon reading
the teachings of this specification, will appreciate that, under
appropriate circumstances, considering such issues as various jewelry
designs, various cross-sectional shapes of jewelry posts 106, and
ergonomic factors, other configurations for connector 100, such
as those adapted for particular posts or combinations of posts,
adapted to posts with sockets instead of grooves 103, etc., may
be used with connector 100.
[0019] Jewelry post 106 is shown inserted into the web 102 of the
connector 100 through first opening 110. Web 102 is shown as a substantially
closed cylinder having a first end 105 proximate the material 116,
a second end 107 distal from material 116, and a circumferential
portion integral to first and second ends 105 and 107. The closed
cylinder formed by web 102 need not have a regular circular cylindrical
cross section. For example, and without limitation, an oval or triangular
cross section may be used for web 102. Preferably, the first and
second ends 105 and 107 have different external shapes to simplify
putting the connector 100 onto jewelry post 106 in the operational
direction, as shown. The first end 105 has a first opening 110 adapted
to receive jewelry post 106. In a particular embodiment, a single
connector 100 may have a plurality of openings 110 in first end
105, such openings sized, shaped, and arranged to receive multiple
jewelry posts 106 from a single article of jewelry 114. In another
particular embodiment, a single connector 100 may have a plurality
of openings 110 in first end 105, such openings sized, shaped, and
arranged to receive jewelry posts 106 each from a plurality of articles
of jewelry 114. The second end 107 preferably has a second opening
112 that is coaxial with first opening 110, as shown. In particular
embodiments, second end 107 may have a plurality of second openings
112 aligned coaxially to first openings 110. Second opening 112
allows jewelry posts 106 of various lengths to be received by the
connector 100. The center of first opening 110 and the center of
second opening 112 define a longitudinal axis 101 of connector 100,
as shown. The funnel shape of the interior of the second end 107
assists in aligning the jewelry post 106 with the second opening
112.
[0020] Although FIG. 1A shows that the external shape of second
end 107 reflects the internal shape of second end 107, the internal
funnel shape of second end 107 need not determine the exterior shape
of second end 107. In a particular embodiment, for example and without
limitation, second end 107 may have a funnel interior shape and
a circular cylindrical exterior shape. The web 102 is configured
to prevent direct manipulation (as by human fingers) of the engaging
members 104 or direct manipulation (as by an object) of the engaging
members 104 by any means integral to connector 100. In some embodiments,
the web 102 may have additional openings in web 102 created within
the constraint that the engaging members 104 may not be manipulated
directly by hand. The web 102 is preferably made of any substantially
rigid non-magnetic or magnetically permeable material. For safety,
the web 102 is preferably not made of extremely hard metal so that
the connector 100 may be cut off in an emergency. Those skilled
in the art, upon reading the teachings of this specification, will
appreciate that, under appropriate circumstances, considering such
issues as various jewelry designs, various cross-sectional shapes
of jewelry posts 106, materials compatibility, manufacturing costs,
and ergonomic factors, other configurations for web 102, such as
those adapted for particular posts or combinations of posts, nonmagnetic
actuation, ease of use, etc., may be used with connector 100.
[0021] Engaging members 104 are preferably coupled to the interior
surface of the web 102 and preferably extend to a position operable
to engage a jewelry post 106. End pieces 108 are sized, shaped,
and arranged to be inserted into groove 103 to limit the motion
of the jewelry post 106 relative to the connector 100. In an exemplary
preferred embodiment, magnets 109 are coupled to end pieces 108,
preferably with their magnetic poles aligned to repel each other.
The reasons for this will be discussed further in the description
of FIG. 2. Magnets 109 preferably have very strong magnetic fields,
more preferably are rare-earth magnets, and most preferably are
magnets that comprise neodymium. The end pieces 108 are preferably
shaped to fit within groove 103 in such a manner that manually removing
the connector 100 from the jewelry post 106 is not possible once
the connector 100 is installed.
[0022] While engaging members 104 are shown as reed springs, the
invention is not so limited. Any biased extensions operable to engage
a jewelry post 106 may be used for engaging members 104. For example
and without limitation, engaging members 104 may each be pivotable
rigid extensions biased by coil springs. Preferably, the dimensions
of the connector 100 should provide a connector 100 that engages
jewelry post 106 at second opening 112 before the engaging members
104 engage the groove 103 in the jewelry post 106. In a particular
embodiment, jewelry post 106 may have a plurality of grooves 103
and each engaging member 104 may engage only one of the grooves
103. In another particular embodiment, grooves 103 may be partially
circumferential grooves, or sockets, and each engaging member 104
may be sized, shaped, and arranged to engage only one socket, making
the correct rotational orientation of the connector 100 to the jewelry
post 106 essential for engagement. Those skilled in the art, upon
reading the teachings of this specification, will appreciate that,
under appropriate circumstances, considering such issues as various
magnetic material strengths, various designs of jewelry posts 106,
load requirements, and ergonomic factors, other configurations for
engaging member 104, such as those adapted for particular posts
or combinations of posts, those using flanges, very high frictional
abutments, spring-loaded extensions, etc., may be used with connector
100.
[0023] FIG. 1B is a sectional elevation view illustrating an exemplary
jewelry post connector 100 in an installed position with engaging
members 104 in a first position, according to the present invention.
End pieces 108 are engaged in groove 103 to prevent removal of connector
100 from the jewelry post 106 by limiting the motion of the connector
100 relative to the jewelry post 106. Material 116 has been slightly
compressed by abutment of the first end 105 to the material 116.
Article of jewelry 114 is held securely to material 116 as a result
of the installation of the connector 100. The configuration shown
in FIG. 1B is the preferred operational configuration of connector
100. Those skilled in the art, upon reading the teachings of this
specification, will appreciate that, under appropriate circumstances,
considering such issues as jewelry posts 106 having multiple grooves
103, jewelry posts 106 having irregular or asymmetrical cross-sections,
the use of means other than magnets 109 to move the end pieces 108,
and ergonomic factors, other designs for engaging member 104, end
piece 108, and magnet 109, such as those adapted for particular
posts or combinations of posts, those adapted to be actuated for
removal by inserted prongs, etc., may be used with connector 100.
[0024] FIG. 2 is a sectional elevation illustrating an exemplary
jewelry post connector 100 being acted upon by required complimentary
separate actuator 200 (hereinafter "actuator") to move
the engaging members 104 and end pieces 108 to a second position,
according to the present invention. Actuator 200 includes a housing
202 for housing batteries 204, electromagnets 208, and wiring 212
for coupling the energy from the batteries 204 to the electromagnets
208 under the control of switch 206 having push-button 210. The
electromagnets 208 are oppositely disposed across a cavity 203 that
is sized, shaped, and arranged to receive connector 100. Considerable
variation in the design of housing 202 is comprehended by this disclosure.
The primary constraint for the design of a housing 202 for pierced
articles of jewelry 114 being that the cavity 203 must be able to
receive connector 100 when connector 100 is in place on a pierced
human body part. Actuators 200 designed only for articles of jewelry
114 that are used on articles of apparel may be less constrained.
Any type of battery (lithium-ion, nickel-Cadmium, lead-acid, etc)
may be used for batteries 204. Batteries 204 with high energy densities
are preferred. Rechargeable batteries 204 may be used. In a particular
embodiment, an alternate energy storage device, such as a small
ultracapacitor, may be used in place of batteries 204. In another
particular embodiment, an alternate energy supply, such as the output
of an appropriately sized transformer plugged into a wall outlet,
may substitute for batteries 204. Those skilled in the art, upon
reading the teachings of this specification, will appreciate that,
under appropriate circumstances, considering such issues as energy
supply, location of the article of jewelry 114, and ergonomic factors,
other designs for the actuator 200, such as those adapted for a
particular body piercing, those adapted to be supplied with energy
from various sources, etc., may be used with connector 100.
[0025] Each electromagnet 208 is configured to magnetically attract
the respectively proximal magnet 109 and to magnetically repel the
respectively distal magnet 109. For this to be possible, the magnetic
poles of the magnets 109 must be oriented for mutual magnetic repulsion.
Preferably, electromagnets 208 are used for actuation, as shown.
In an alternate embodiment, the actuator 200 may comprise one or
more permanent magnets instead of electromagnets 208. The spring
coefficient of the engaging members 104 and the magnetic field strengths
of magnets 109 are preferably selected to prevent the repulsive
forces of the magnets 109 alone from causing the end pieces 108
to disengage from the jewelry post 106. Those skilled in the art,
upon reading the teachings of this specification, will appreciate
that, under appropriate circumstances, considering such issues as
jewelry posts 106 having multiple grooves 103, jewelry posts 106
having irregular or asymmetrical cross-sections, the use of means
other than magnets 109 to move the end pieces 108, and ergonomic
factors, other designs for the actuator 200, such as those adapted
for particular posts or combinations of posts, those adapted to
be actuated for removal by inserted prongs, etc., may be used with
connector 100.
[0026] FIG. 3A is a sectional elevation view illustrating an exemplary
jewelry post connector 300 in an intermediate position while being
installed, according to a second embodiment of the present invention.
In the second embodiment, the magnetic end pieces 308 serve both
as magnets 109 and as end pieces 108 adapted to fit in groove 103.
Opening 110 is preferably sized, shaped, and arranged to slidingly
receive jewelry post 106. In a particular embodiment, first end
105 of web 102 may have increased thickness to assist in aligning
the jewelry post 106 within the web 102. Those skilled in the art,
upon reading the teachings of this specification, will appreciate
that, under appropriate circumstances, considering such issues as
developments of new jewelry posts 106 or combinations of new jewelry
posts 106, such as those adapted for specialized articles of jewelry
114, etc., may be used with jewelry post connector 300.
[0027] FIG. 3B is a sectional elevation view illustrating an exemplary

a second embodiment of the present invention. Magnetic end pieces
308 are shown engaging groove 103 to prevent manual removal of the
jewelry post connector 300 from the jewelry post 106. In some embodiments,
web 102 may be decorated. For example and without limitation, the
exterior surface of web 102 may be engraved, embossed, anodized,
colored, appliqued, and/or encrusted. Those skilled in the art,
upon reading the teachings of this specification, will appreciate
that, under appropriate circumstances, considering such issues as

rotating the complimentary separate actuator 400 about a longitudinal
axis 406 through the center of the cavity 404, in order to orient
the electromagnets 208 inside case 401 to the magnets 109 inside
the connector 100. Cavity 404 is preferably marked with pole alignments
for the electromagnets 208, as shown. Complimentary separate actuator
400 operates on the same principle as actuator 200. In use, the
complimentary separate actuator 400 is manipulated to receive connector
100 into cavity 404, the complimentary separate actuator 400 is
oriented to align the electromagnets 208, and the push-button switch
410 is pushed to energize electromagnets 208, thereby magnetically
urging magnets 109 away from jewelry post 106 and releasing the
connector 100 from jewelry post 106. Those skilled in the art, upon
