Patent Description
FIELD OF THE INVENTION
[0001] The present invention deals with jewelry and more specifically
hands-free jewelry.
BACKGROUND OF THE INVENTION
[0002] Bracelets and like jewelry are typically worn on the wrist
or ankle, and must include a mechanism to secure the jewelry piece
in place. Typically, there are two ways to attach a jewelry piece
such as a bracelet to the wrist or ankle. First, the jewelry piece
may separate and wrap around a wrist or ankle, in which case there
must be a clasp mechanism to attach the ends together and secure
the jewelry piece so that it remains in place. Second, the jewelry
piece remains intact but is extendible to expand and slide over
the hand or foot, then contract to remain in place on the wrist
or ankle.
[0003] Clasps can be difficult to use especially for jewelry worn
on the wrist since the clasp must be operated with one hand. Some
users have difficulty with manual dexterity and may find any clasp
difficult to operate. Virtually everyone has experienced the difficulty
of closing a bracelet around one's own wrist. Whether young or old,
ambidextrous or not, trying to put a bracelet on one's own wrist,
or trying to take it off, is extremely difficult, requires total
concentration and usually, a number of failed attempts. The elderly
especially experience difficulty putting on and removing jewelry
since they may experience arthritis and similar conditions that
cause the loss of fine motor skills in the wrists, hands and fingers.
Furthermore, it also is common for the elderly to have eye conditions
which impair visual acuity, particularly at close distances.
[0004] Accordingly, there is a need for hands-free jewelry. At
the time of this writing, there have been no attempts made to design
or provide such jewelry.
SUMMARY OF THE INVENTION
[0005] In accordance with an embodiment of the present invention,
hands-free jewelry is provided. The jewelry comprises a number of
sections, preferably two, joined together by a hinge so that each
section has a hinged end and a free end. A clasping mechanism on
their free ends is constructed and arranged to removably attach
the free ends together to maintain the jewelry in a closed position.
At their hinged ends, each section has a lever extension providing
the mechanism by which the jewelry is closed without using any hands.
The lever extensions extend from opposite sides of the hinge in
opposite directions so that a space is defined between them. Placing
a bodily member, such as a wrist, into the space between the levers
and onto the hinge to apply downward force, causes the sections
to rotate about the hinge. With sufficient force and rotation, the
free ends come into contact, causing the clasping mechanism to catch
and join the free ends together.
[0006] To open the jewelry, a button is provided that, when pushed
against a surface, disengages the clasping mechanism and opens the
jewelry for removal.
[0007] In more detail, the hands-free jewelry clasp comprises a
first section, a second section movably connected to the first section,
a first lever connected to the first section, and a second lever
connected to the second section. The levers are constructed and
arranged so that a body member inserted between said first and second
sections is able to move at least the first lever to rotate the
first section into contact with the second section.
[0008] The jewelry further comprises a first free end on the first
section having a slot, and a tab on a second free end of the second
section wherein the tab and slot are constructed and arranged to
removably attach to each other.

DETAILED DESCRIPTION
[0017] In accordance with an embodiment of the present invention,
hands-free jewelry is provided. The jewelry comprises a number of
sections, preferably two, joined together by a hinge so that each
section has a hinged end and a free end. A clasping mechanism on
their free ends is constructed and arranged to removably attach
the free ends together to maintain the jewelry in a closed position.
At their hinged ends, each section has a lever extension providing
the mechanism by which the jewelry is closed without using any hands.
The lever extensions extend from opposite sides of the hinge in
opposite directions so that a space is defined between them. Placing
a bodily member, such as a wrist, into the space between the levers
and onto the hinge to apply downward force, causes the sections
to rotate about the hinge. With sufficient force and rotation, the
free ends come into contact, causing the clasping mechanism to catch
and join the free ends together.
[0018] FIG. 1a shows a bracelet in accordance with an embodiment
of the present invention in an open configuration. A hinge 20 joins
a semi-circular first piece, or left side 12 and second piece, or
right side 14. The left side 12 has a lever 18 extending from its
hinged end and the right side 14 has a lever 16 on its hinged end.
Each side 12 and 14 preferably form half the jewelry.
[0019] The left side closing lever 18 and the right side closing
lever 16 should be constructed and arranged to avoid contact and
interference with each other during operation of the bracelet. In
this example, the left side lever 18 is shaped like a tab, narrower
than the right side lever 16 which is shaped like a U and positioned
to surround either side of the slot or lever 16.
[0020] FIG. 1b shows a close-up view of the hinge and lever arrangement
of the jewelry shown in FIG. 1a. The hinge 20 connects the left
side 12 and the right side 14 at their hinged ends, 12.1 and 14.1,
respectively. In use, when pressure is applied at the position and
in the direction of arrow 100, the hinge 20 forms the fulcrum for
the rotation of the left side 12 and the right side 14.
[0021] The left side 12 has a lever extension 18 extending passed
its hinged end 12.1 and the hinge 20. The left lever 18 has a free
end 18.1 and a base end 18.2. The base end 18.2 is attached to the
hinged end 12.1 of the right side 14 and the free end 16.1 extends
upwardly from the hinged end 14.1, passed the hinge 20. Movement
of the lever 18 by manipulation of the free end 18.1 causes reciprocal
movement of the left side 12 about the hinge 20. For example, pushing
down on the free end 18.1 of the left lever 18 causes the left side
12 to swing up, around the hinge 20. Pulling up on the free end
18.1 of the left lever 18.1 causes the left side 12 to swing downwardly
about the hinge 20.
[0022] The same is true of the right side 14, the right side 14
has a lever extension 16 extending passed its hinged end 14.1 and
the hinge 20. The right lever 16 has a free end 16.1 and a base
end 16.2. The based end 16.2 is attached to the hinged end 14.1
of the right side 14 and the free end 16.1 extends upwardly from
the hinged end 14.1, passed the hinge 20. Movement of the lever
16 by manipulation of the free end 16.1 causes reciprocal movement
of the right side 14 about the hinge 20. For example, pushing down
on the free end 16.1 of the right lever 16 causes the right side
14 to swing up, around the hinge 20. Pulling up on the free end
16.1 of the right lever 16 causes the right side 14 to swing downwardly
about the hinge 20. It is this hinge and lever arrangement depicted
in FIG. 1b that allows for the hands-free operation of the jewelry.
When pressure is exerted onto one or both levers 16 and 18, the
pressure will cause the left side 12 and the right side 14 to rotate
around the hinge 20 and bring the two sides into contact at their
free ends.
[0023] Each lever 16 and 18 is connected to its respective side
14 and 12 at its base end 16.2 and 18.2. The levers 16 and 18 may
be soldered onto the hinged end 14.1 and 12.1 of the jewelry piece
14 and 12 or formed as a part of the piece 12 and 14. The hinge
20 is an ordinary pin hinge arrangement as is well known.
[0024] Referring back to FIG. 1a, at the free end of the left side
12 is a tab 22 and a button 26. At the free end of the right side
14 is a slot 24 designed to receive the tab 22. When pressure causes
the free ends of the two sides 12 and 14 to come together, the tab
22 will insert into the slot 24 until the tab 22 clicks into the
slot 24. Pressing the button 26 will release the tongue from slot
22 and open the bracelet. A typical side squeeze clasp, which is
well-known in the art, is sufficient to provide the automatic operation
of the clasp.
[0025] To apply force on the levers 16 and 18 and close the bracelet
around a wrist (not shown), the wrist is inserted into the interior
of the open bracelet, between the tab 22 and slot 24, usually sideways
so that the side of the wrist rests in between the slot lever 16
and tab lever 18. Pushing down on the bracelet above the hinge 20
in the direction and position of arrow 100 causes the two sides
to rotate about the hinge 20 and bring the tab 22 into the slot
24.
[0026] In further detail, the hinge 20 acts as a fulcrum point
for the left side 12 and the right side 14. When force is applied
in the direction and at the position of arrow 100, the left side
12 will move in the direction of the arrow 108 and the right side
in the direction of the arrow 106. The left side closing lever 18
will move in the direction of arrow 104 and the right side closing
lever 16 moves in the direction of arrow 102.
[0027] FIG. 2 shows the bracelet of FIG. 1a in a closed configuration
taking a circular form to securely adorn a wrist. The tab 22 is
fully inserted into the slot 24 and securely holds the tab 12 and
slot 14 sides together. In this closed configuration, the tab 18
and slot 16 levers rest close to the interior of the resulting closed
bracelet so that they are out of the way and provide a comfortable
fit.
[0028] FIG. 3a is a close up view of the slot 24 and tab 22 arrangement
according to an embodiment of the present invention. A tab 22 is
fixedly attached to the tab side at its base with an attached end
22.1 and a free end 22.3 free to move sideways as indicated by arrow
300. Preferably, the tab is tapered with a notch 22.5 on the outside
of the free end 22.3. On the outer tip of the free end 22.3, a button
26 is provided that allows sideways manipulation of the tab 22 by
pressing the button inwardly, towards the bracelet. Pressing the
button 26 compresses the tab 22, pinching the free end 22.3 and
the fixed end 22.1 together, making the tab 22 narrower overall.
The natural spring of the tab 22 will exert an opposite force to
spread the tab 22 wider.
[0029] FIG. 3b shows the mechanism of FIG. 3a in a partially closed
configuration. As the tip 22.7 of the tab 22 is inserted into the
slot 24, the top sidewall 24.1 and the bottom sidewall 24.2 exert
an inward compression force on the tab 22, bringing the free end
22.3 closer to the fixed end 22.1. The tab 22 flexes at its tip
22.7 and is pinched until the notch 22.5 fits over the sidewall
24.1 and the sidewall 24.1 fits into the notch 22.5. The notch 22.5
should be slightly wider than the thickness of the slot 24.
[0030] FIG. 4a shows a bracelet 50 in accordance with an embodiment
of the present invention worn on the wrist of an arm 52. The button
26 is this example, faces down. A structure 54, which may be a desk
or table, provides the means to apply force to the button 26 and
open the bracelet 50 as shown in FIG. 4b. The hand is cocked back
to fully expose the button 26 to the top of the structure 54. By
simply pushing the button 26 against the top of the structure 54,
the clasp on the bracelet 50 will open.
[0031] FIG. 4c shows the case where the bracelet 50 is turned around
and the button 26 faces up. In this case, the hand may or may not
be pulled back and the bracelet 50 is pulled up next to the structure
54, with the bottom surface of the structure pushing down on the
button 26.
[0032] Alternatively, the bracelet can be turned so that the button
is on the top of the hand. Operation is the same, the button is
pressed against a surface and the clasp will automatically open,
providing hands-free operation.
[0033] The principles disclosed herein may also be used for rings,
eliminating the problems with ring removal. A ring made in accordance
with an embodiment of the present invention would work the same
way and resemble a miniature version of the bracelet enclosed herein.
The finger upon which the ring would be worn is pressed onto the
center of the open ring, closing the ring around the finger in the
same way the bracelet closes around a wrist. Removal is the same;
the button is pushed against a structure, causing the tab to pull
itself out of the slot.
[0034] It should be understood that other clasps and closure mechanisms
may be used in conjunction with the hinge and lever arrangement
disclosed herein. The tab and slot arrangement is only an example
and meant to illustrate but one way to hold the jewelry in a closed
position.
[0035] In the preceding specification, the invention has been described
with reference to specific exemplary embodiments thereof. It will
however, be evident that various modifications and changes may be
made thereto without departing from the broader spirit and scope
of the invention as set forth in the claims that follow. The specification
and drawings are accordingly to be regarded in an illustrative manner
rather than a restrictive sense. |
