Definitions

  • the present invention is directed to an improvement in jewelry, and more specifically relates to an item of jewelry, such as a ring or a bracelet suitable for wearing over a person's finger or wrist, having a spring actuated size adjustment mechanism.
  • ring sizes or a wrist size in the case of a bracelet
  • various factors ultimately affect a person's actual ring size on a given day For example, various physiological conditions are known to affect ring size. A person's fingers might swell as a result of hormonal changes or water retention. Water retention might be exacerbated by other factors such as the amount of salt intake as part of a person's diet. Weight gain and weight loss over a period of time also affect a person's ring size. Even weather conditions on a given day may affect ring size. Additionally, often a person's knuckles are greater in size than the person's ring size. As a result, it is often difficult to get a properly sized ring placed over a person's knuckle.
  • a person's ring size may vary greatly from one day to the next, from one season to the next, and from one year to the next. Since people often purchase jewelry to be worn frequently, or even daily, over a large period of time, these changes in ring size have proven to be annoying, costly and extremely problematic. For example, if a person's ring is too tight on a given day, the person might not be able to place the ring on his or her finger that day and might be forced to leave it at home. This is very annoying to a person who purchased the ring to wear every day, or who merely wanted to wear the ring on that particular day. Similar problems may arise if the ring is too loose on a given day and a person is forced to leave the ring at home or alternatively risk losing the ring if it falls off the person's finger unexpectedly.
  • Sizing down a ring can also be accomplished in a variety of ways. Where the change is small, the size can be made smaller by mechanically compressing the ring. If the ring is made of several metals (such as white and yellow gold), compression is typically not used as it might result in breaking the two metals apart. Where the change of size is greater, or where stones are included in the ring, sizing down the ring requires removing any stones. cutting out a portion of the ring, and then re-soldering the remaining portions together. This method is more costly and provides a greater risk of damaging the ring.
  • U.S. Patent No. 5,412,956 to Levy discloses a variable sized hinged ring that may be worn in a closed position or in a number of open positions.
  • the ring includes a center shank member and first and second side shank members, each of which is hinged to the center shank member and an elongated sizing section that has a plurality of stops for determining the circumferential ring size.
  • the ring can be opened and closed by the wearer to provide several different ring sizes.
  • One problem with this system is that it can only accommodate the ring sizes corresponding to the stops provided.
  • Another problem is that is must be manually opened and closed by the user.
  • the interior surface of the ring no longer presents a smooth, uninterrupted surface to the wearer and is thus very uncomfortable to wear.
  • the finger opening no longer has a generally constant shape and therefore the appearance to the user and others is much less attractive than a standard shaped ring.
  • Erb discloses a self sizing adjustable ring including a U-shaped shank member and a bridge member permanently connected to the shank member but movable up and down the shank member to adjust for the size of a user's fingers.
  • the bridge member is manually adjustable by the user over a variety of different positions and is held in place using a frictional force created between the bridge and the shank member.
  • One problem with this system is that it can only be used with U-shaped ring bodies.
  • Another problem is that the bridge member is kept in place using frictional forces. It would be quite easy for the bridge member to disengage and move unintentionally.
  • the disclosed ring design requires a securement member attached to the bridge member to frictionally engage the exterior surface of the shank member. This results in an unattractive appearance to the user and others because the disclosed ring does not provide the appearance of an ordinary ring.
  • Miller discloses a finger ring size adjusting device and method including a ring shank and a cradle which is biased radially inward from the shank and is moveable between a retracted position and an adjusted position for reducing ring size.
  • the cradle may be biased inwardly toward the adjusted position by a leaf spring in one embodiment, and by a lever arm in an alternate embodiment.
  • One problem with this system is that the disclosed system includes only one cradle at the bottom of the ring shank. Only two possible ring sizes are provided - a smaller ring size and a larger ring size. There is no accommodation of a variety of ring sizes.
  • the ring when the cradle is in its inward position, the ring does not provide a unitary, smooth, generally round inner surface.
  • the inner surface would include gaps in which a user's skin could become pinched.
  • the appearance of the ring is less attractive as the lever or spring is visible through the opening in the ring.
  • Another ring adjustment device is known from DE-11 40 768 B .
  • a ring having a size that can be adjusted simply and easily by the wearer to account for day to day fluctuations in a person's ring size and to account for variations in finger size such as those caused by a larger knuckle region.
  • an adjustable ring that can accommodate a variety of different ring sizes within a specified range.
  • an adjustable ring such that a jeweler can stock rings in fewer sizes.
  • One embodiment of the present invention is directed to adjustable jewelry according to the claims comprising a ring portion having an outer surface and an inner surface defining an opening for receiving an appendage of a wearer therethrough; a channel is formed into the ring portion, a plurality of size adjustment segments are disposed in the channel, and an elastic member is disposed in the channel to bias the segments radially inwardly.

  • the last movable segment with a spring stop 646 can then be inserted into the channel 608 by inserting the flange 632 on the opposite end to the end with the spring stop 646 with the remaining end of the spring member 660 engaged in the spring stop 646.
  • FIG, 6C is a cross sectional view of the ring taken through lines 6c-6c of FIG. 6B .
  • the inner surface 604 of the ring shaped frame and the movable segment(s) 630 are shown, with the movable segment 630 being located within the channel 608.
  • the inner surface 636 of the movable segment 630 is shown protruding through the channel opening 612, while the flanges 632 are confined within the channel 608 behind the channel opening 612.
  • the spring element 660 is preferably in its natural "C" shape such that the movable segments 630 protrude into the channel opening 612 to a fully extended position to define a reduced size for the jewelry.
  • the spring element 660 may always be in some state of compression. The amount of protrusion of the movable segment 660 into the opening 670 is selected to create the desired amount of variation in the size of the ring opening.
  • the movable segments 630 retract into the channel opening 612, expanding the spring element 660 out of its natural shape to have a wider opening of the "C", and defining a larger opening 670 to accommodate a larger appendage of the user.
  • the expansion and retraction of the spring element 660 provide for an adjustable size opening 670 for the user's appendage.
  • the movable segments 630 can move among a plurality of positions, thus accommodating a range of openings (i.e., a range of ring or bracelet sizes).
  • the flange portions 632 have a sufficiently small width in comparison to the width of the channel 608 so as to not interfere with the movement of the movable segments 630 within the channel 608.
  • the flange portions 632 can be made to have substantially the same width as the width of the channel 608 so that the flanges are in sliding contact with the side walls of the channel 608. The amount of resulting frictional force between a flange and the side wall can be adjusted empirically taking into account, for example, the material(s) of the ring shaped frame 600 and the movable segments 630, the spring constant of the spring element 660, the contact surface area between the flange and the channel wall, and the like.
  • the amount of frictional force is selected to allow the movable segments 630 to move yet the frictional force sufficiently oppose the biasing force of the spring element 660 so as to alleviate some of, or to reduce, the constant pressure being applied to the skin of the wearer so that it does not become overly excessive.
  • the amount of the frictional force may be selected to sufficiently oppose the bias force of the spring element 660 such that once a movable segment becomes stationary at a position between a fully extended position (i.e., defining the smallest size of the opening 670) and a fully retracted position (i.e., defining the largest opening 670), the bias force from the spring element 660 is sufficiently overcome so that the movable segment can remain in that position indefinitely until an external force disrupts the balance between the two opposing forces to dislodge the flange from the side wall of the channel, and to cause the bias force of the spring element 660 to move the movable segment.
  • the jewelry according to this aspect of the embodiment can be made to ''remember"' the size adjusted to closely match the size of the wearer.
  • the outside surface of the ring body or the ring shaped frame may be plain or it may be decorated in any desired way.
  • the outer perimeter of the ring shaped frame can be adorned with one or more mounting sections 640 for mounting one or more jeweled stones, such as a diamond, as is known in the art.
  • the outer surface of the ring portion have been described herein to be generally arc shaped, any shaped surfaces may be utilized within the present invention. For example, a flat shaped outer surface is often preferable in rings for men and where stones are to be mounted on top of the ring.
  • the adjustable jewelry of the present invention may be created in any of a variety of sizes and may be caused to adjust within various size ranges.
  • an adjustable size finger receiving opening that accommodates sizes within a range of 1 mm or approximately one ring size (most individuals would typically not have a need for larger size adjustments)
  • the adjustment mechanism of the present invention may be modified to accommodate smaller (i.e., half size) or larger (i.e., two sizes) adjustment ranges.
  • the present invention has been generally described herein with respect to rings worn over a wearer's finger, the present invention applies equally to other types of jewelry, such as bracelets, where similar adjustments would be applicable and beneficial to a wearer.
  • the disclosed adjustment mechanisms could be utilized in conjunction with a bracelet to provide a way for adjusting the diameter of the interior wrist-receiving opening of the bracelet.
  • a wearer can place the bracelet over the hand and onto the wrist without having to open the bracelet, stretch the bracelet, or utilize a bracelet which is ultimately too large for the wearer's wrist.
  • the outside portion of the bracelet could then be decorated or designed in any desired way, all within the scope of the present invention.
