Ear clip for an earring

An ear clip for an earring comprising a connector and a clip arm, the connector being adapted to attach to an ornamental piece and having a first cup, the clip arm having a second cup which receives the first cup to form a pivot, the pivot creating a friction fit between the cups so as to allow the clip arm to be positioned as desired with respect to an earlobe.

FIELD OF THE INVENTION 
This invention relates to the field of jewelry clips and more particularly 
to an ear clip for a hinged type of earring. 
BACKGROUND OF THE INVENTION 
There are several types of arrangements by which earrings are held to an 
earlobe. Earrings for pierced ears, for example, employ a post with a cap. 
Another arrangement involves a screw-threaded post, which can be tightened 
against the earlobe. Another common arrangement involves the use of a 
hinged arm of some type, wherein the arm, which is often spring-loaded, 
presses against the earlobe. In the latter case, the earring usually has 
two basic parts, an ornamental piece and the attachment mechanism 
including the arm, which is called an ear clip. 
There are several drawbacks to such prior art ear clips. First, many prior 
art ear clips of the hinge type are made of a number of separate parts, 
and some of these necessarily small parts are rather complex. This 
significantly increases the cost of the mechanism. The amount of force 
exerted by the hinge-type clip is also a problem. Most prior art ear clips 
have one setting which is used by everyone regardless of earlobe thickness 
or individual preference. Hence, a prior art ear clip may be too tight and 
uncomfortable for some wearers and too loose for others. The former 
problem is particularly acute if the mechanism includes the usual 
spring-biasing means to help keep the arm in its closed setting against 
the earlobe. 
A further drawback of the prior art ear clips of the hinged type is that 
the device lacks aesthetic appeal. Because of the number of parts, their 
sizes and shapes, the mechanism is neither symmetrical nor simple, which 
detracts from the earring's appearance. 
Accordingly, one object of this invention is to provide an earring or other 
piece of jewelry with an improved attachment clip. 
Another object of the invention is to provide an ear clip for an earring 
which uses the frictional resistance between its parts to set and hold the 
positioning of its arm with respect to the earlobe as desired. 
Another object of the invention is to provide an ear clip for an earring 
wherein the clip has few parts and is easy to manufacture. 
Another object of the invention is to provide an ear clip for an earring 
wherein the main features of its moveable parts are enclosed and hidden 
from view. 
Another object of the invention is to provide an ear clip for an earring, 
having a compact connection between its moving pieces. 
SUMMARY OF THE INVENTION 
The invention comprises an ear clip for an earring having a connector and a 
clip arm. The connector is adapted to be attached to an ornamental piece 
for the earring, and the clip arm is pivotably attached to the connector 
at a joint so that the arm can be positioned as desired and held in any 
such position by the frictional resistance between the connector and arm 
at the joint. 
In the preferred embodiment, a connector comprises an attachment foot, a 
neck, and a cup. The foot is essentially flat and adapted to attach to an 
ornamental piece by soldering, gluing or other conventional means. The 
neck extends from one end of the foot and supports an attachment cup 
having a lip. The clip arm comprises an expanded engagement paddle and a 
shank. Two receiving cups having lips are disposed on the end of the 
shank, and the cup of the connector fits therebetween to form a joint 
about which the engagement paddle can pivot. A friction fit is obtained 
between the cup and its lip of the connector and the receiving cups and 
their lips of the clip arm so that the engagement paddle can be held at a 
variety of different angles with respect to the connector. In operation, 
the engagement paddle engages the earlobe of the wearer, and the amount of 
force exerted by the engagement paddle on the earlobe is adjustable by 
changing the position of the engagement paddle with respect to the 
connector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS 
I turn now to a detailed description of the preferred embodiment, after 
first describing the drawings.

preferred embodiment, showing a clip arm in different positions; 
FIG. 2 is a perspective view of a connector of the preferred embodiment 
prior to assembly; 
FIG. 3 is a perspective view of a clip arm of the preferred embodiment 
prior to assembly; and 
FIG. 4 is a perspective view of the assembled connector and clip arm of the 
preferred embodiment of the invention. 
Structure 
Referring to FIGS. 1A and 1B, an earring incorporating the invention is 
shown at 10. The earring 10 generally comprises an ornamental piece 12 
having a back 14 and an ear clip 20. The earring 10, however, is just 
illustrative, and other types of jewelry articles may be used with the 
clip 20. 
Referring to FIG. 4, the ear clip 20 generally comprises a connector 22 and 
a clip arm 40. The connector 22 is best shown in FIG. 2. It has a foot 24, 
which is attached to the back 14 of the ornamental piece 12 of the earring 
10 when the ear clip 20 is in place. The foot 24 may be attached to the 
back 14 by soldering, gluing or other means. The foot 24 of the preferred 
embodiment is trapezoidal in shape, but other shapes are possible. The 
connector 22 has a neck 26 which extends from one end of the foot 24 at 
approximately a right angle. The end of the neck 26 opposite the foot 24 
is attached to a hollow, cylindrical cup 28 having a rounded outer surface 
30 bounded by a lip 35 having a surface 34 opposite the cup 28. The 
connector 22 is made of a single piece of copper, although other materials 
may be used. The cup 28, which is sometimes referred to as a blind hole in 
the metal fabrication industry, is formed by striking or by coining it 
into the metal. Other methods of making the cup 28 are also possible. 
The unassembled clip arm 40 is best shown in FIG. 3. Clip arm 40 comprises 
an engagement paddle 42, which is integral with a shank 44. In the 
preferred embodiment, engagement paddle 42 has the shape of a loop, 
although other shapes are possible. Two cups 46, 48 are disposed opposite 
each other on the end of the shank 44 away from the engagement paddle 42. 
The paddle 42, the shank 44 and the cups 46, 48 are made of a single, thin 
piece of metal, which is stamped from strip stock using common metal 
stamping operations including punching, notching, parting, bending or 
coining. The cups 46, 48 have rounded outer surfaces 50, 52, recesses 54, 
56 and lips 58, 60 which bound the recesses 54, 56. The cups 46, 48 are 
made in the same manner as the cup 28 of the connector 20. However, the 
cups 46, 48 are larger than cup 28, and cup 28 is designed to fit inside 
the recesses 54, 56 of cups 46, 48. 
The assembled ear clip 20 is best shown in FIG. 4. The cup 28 of the 
connector 20 fits inside recess 56 of cup 48 of the clip arm 40, and the 
cups 46, 48 are pressed together so that lip 58 of cup 46 contacts surface 
34 of cup 28. This is accomplished by use of a press, which pinches the 
cups 46, 48 together when the cup 28 is in place in the recess 56. The 
cups 46, 48 are then struck on their top 49 so as to remove any inherent 
resiliency of the cups 46, 48, which might tend to separate them. This 
forms a joint 70, wherein both cups 46, 48 effectively press on the 
captured portioned of the connector 20 so that the lips 58, 60 on the cups 
46, 48 respectively press on the surface 34 and the lip 35 of the cup 28 
forming a friction fit therewith. It should be noted that cup 46 is not 
actually needed and can be replaced by a flat surface. However, the 
appearance of the ear clip 20 is made symmetrical by the addition of cup 
46. Of course, it is also possible to have a pair of cups disposed on the 
connector 22, which capture a single cup disposed on the clip arm shank. 
When assembled, the foot 24 is attached to the back 14 of the ornamental 
piece 12, as shown in FIGS. 1A and 1B. In operation, the earlobe of the 
wearer fits between the engagement paddle 42 and the back 14 of the 
ornamental piece 12. Because of the friction fit at the joint 70, however, 
the engagement paddle 42 can be positioned at any angle desired, and it 
will remain in that position until physically moved by the wearer. Thus, 
any wearer discomfort is avoided, as the amount of pressure exerted by the 
engagement paddle 42 on the earlobe is controlled by the wearer, while 
still providing a suitably tight fit to prevent loss of the earring. 
Other embodiments and advantages of the invention will be apparent to those 
skilled in the art.
