CROSS-REFERENCE
This application is a continuation-in-part application of U.S. Design Application No. 29/213,103, filed Sep. 13, 2004.
FIELD OF THE INVENTION
The present invention relates to jewelry and ornamental apparel. Specifically, the present invention relates to lockets.
BACKGROUND OF THE INVENTION
For millennia, people have adorned themselves with decorative jewelry. It has been the practice of some to wear jewelry that contains the image or likeness of another, such as a loved one or family member, within. A specific type of jewelry that is used for this purpose is a locket. Lockets have been designed in many shapes and sizes. One of the most traditional designs for a locket is a simple two piece locket that opens and closes in a manner similar to that of a clam shell. The image or likeness of a person would be kept inside of the locket and would be displayed when the locket was opened and covered when the locket was closed or locked.
It is often desirable to locket wearers that the locket be able to hold more than one image or likeness. This issue has been addressed by placing at least one image or likeness on both of the inner panels of a traditional clamshell locket. The issue has also been addressed by developing lockets which have a plurality of hingedly connected panels. The hingedly connected panels are expanded and condensed in the style of an accordion. Generally, with accordion style lockets, there are two decorative outer panels that close together to form the outer surfaces of the locket when the locket is disposed in a closed or compacted state.
There have been various different types of accordion style lockets. For example, U.S. Pat. No. 4,882,915 (the '915 patent) discloses an accordion style locket having circular interior panels and generally bowl shaped outer panels. The locket disclosed in the '915 patent is an accordion style locket that closes into the shape of a ball for general wearing as ornamental jewelry. The locket disclosed in the '915 patent is held in a closed position by two clamping arms that frictionally engage the lower bowl shaped outer panel, thereby restraining the lower outer panel in close proximity to the upper outer panel with the interior panels compressed between the two outer panels. Some problems with earlier locket design were their bulk and their lack of reliable fasteners to keep them in a closed position. Furthermore, it is desirable that the locket have ornamental designs on the back side of the interior panels of the locket.
It would be beneficial to provide a locket that combined a compact shape, accordion design, ornamental panels and a secure locking mechanism into a decorative piece of jewelry.
BRIEF SUMMARY OF THE INVENTION
Briefly, the invention provides a releasably lockable locket having a hub, a lock and an expandable plurality of panels extending between the lock. The hub comprises a locking cavity having an upper wall and a lower wall. The lock has an upper biasing member and a lower biasing member. The upper biasing member and the lower biasing member are connected at a lock tip and biased away from each other. The lock is releasably, frictionally engageable with the locking cavity. The plurality of successive hingedly connected panels extends between the hub and the lock. The first panel of the successively hingedly connected panels is hingedly connected to the hub. The last panel of the successively connected panels is hingedly connected to the lock. At least one of the panels in the plurality of successive hingedly connected panels is adapted to retain a presentment therein.

The third left hinge protrusion 150c is hingedly connected to a fourth central hinge protrusion (not shown) and a third right hinge protrusion (not shown) via the fourth hinge 112d. A similar hinge arrangement is preferred for successive panels. The hinges 112a, 112b, 112c, 112d and 112e are disposed, with respect to each panel 110a, 110b, 110c, 110d and 110e, to allow approximately 180 degrees of rotation for the panels 110a, 110b, 110c, 110d and 110e about each hinge 112a, 112b, 112c, 112d and 112e. The range of rotation for each panel 110a, 110b, 110c, 110d and 110e about their respective hinges 112a, 112b, 112c, 112d and 112e allows for the accordion style expansion of the locket 100 from the closed position shown in FIG. 2 to the open position shown in FIG. 1.
Referring to FIGS. 4 and 5, there are preferably an odd number of panels in the plurality of panels 110a, 110b, 110c, 110d and 110e. While five panels 110a, 110b, 110c, 110d and 110e are shown, those skilled in the art will recognize that only 3, as well as 7, 9, 11 panels may be used without departing from the scope of the present invention. Each of the panels in the plurality of panels 110a, 110b, 110c, 110d and 110e is constructed to retain a presentment (not shown). The presentment may be a photo, drawing, note, clipping, lock of hair, artifact, piece of memorabilia or any other item that would fit within the panel 110a, 110b, 110c, 110d and 110e. Each panel of the plurality of photo panels 110 has a cavity for retaining a presentment (not shown) therein. Preferably, the panel 110 has a backing panel 134a, 134b, 134c, 134d and 134e. Each backing panel 134a, 134b, 134c, 134d and 134e is generally rectangular in shape. Each backing panel 134a, 134b, 134c, 134d and 134e may be solid, engraved or carved in the shape of a letter, a design or some other indicia. Preferably, a photo frame 136a, 136b, 136c, 136d and 136e is fixedly attached to each backing panel 134a, 134b, 134c, 134d and 134e around the perimeter the side of each back panel 134a, 134b, 134c, 134d and 134e where the presentment is retained. A retaining frame 138a, 138b, 138c, 138d and 138e is fixedly connected to each photo frame 136a, 136b, 136c, 136d and 136e, respectively. Each retaining frame 138a, 138b, 138c, 138d and 138e is disposed on the opposite side of the photo frame 136a, 136b, 136c, 136d and 136e than the back panel 134a, 134b, 134c, 134d and 134e. Preferably, each backing panel 134a, 134b, 134c, 134d and 134e, each photo frame 136a, 136b, 136c, 136d and 136e and each retaining frame 138a, 138b, 138c, 138d and 138e have generally the same length ‘L.’
For insertion, each presentment (not shown) is manipulated, by the inserter, in order to fit the presentment through the opening defined by each retaining frame 138a, 138b, 138c, 138d and 138e, having a length “o.” Preferably, each presentment would then be inserted through the opening defined by retaining frame 138a, 138b, 138c, 138d and 138e and deposited against each backing panel 134a, 134b, 134c, 134d and 134e. Each presentment is then be released by the inserter and allowed to expand between each respective retaining frame 138a, 138b, 138c, 138d and 138e and the back panel 134a, 134b, 134c, 134d and 134e. After expansion to its original state, each presentment would then be frictionally retained within each panel 110a, 110b, 110c, 110d and 110e, between the panel's 110a, 110b, 110c, 110d and 110e respective retaining frames 138a, 138b, 138c, 138d and 138e and backing panel 134a, 134b, 134c, 134d and 134e. Those skilled in the art will recognize that a presentment may be inserted into the panels in other ways, such as through a slot in a side of each panels 110a, 110b, 110c, 110d and 110e, or through an opening in each of the backing panels 134a, 134b, 134c, 134d and 134e.
Referring to FIGS. 1, 5 and 6 at the bottom of the fifth panel 110e, the panel that is located furthest from the hub 104, a lock hinge 128 connects the fifth panel 110e to a lock 124. The lock 124 consists of a V-shaped wedge 125 and a compression tab 126. The V-shaped wedge 125 of the lock 124 comprises an upper biasing member 161 and a lower biasing member 162. The biasing members 161, 162 are joined together at the tip 160. Preferably, the upper biasing member 161 and the lower biasing member 162 are compressably biased away from each other. Preferably, the lock 124 is constructed of a material that facilitates return to its original shape after biasing, such as spring steel. Those skilled in the art will recognize that the lock 124 may be made from other materials and may be plated in precious metals or adapted to conform with the design of the locket 100.
When the locket 100 is disposed in the closed position, the V-shaped wedge 124 is frictionally retained within a locking cavity 130 of the hub 104. The locking cavity 130 is disposed within the hub 104, preferably in the bottom portion of the hub 104. Preferably, the locking cavity 130 has an opening 132 in the rear of the hub 104. The locking cavity 130 extends from the rear opening 132 forward towards the front of the hub 104. Both the opening 132 of the locking cavity 130 and the lock 124 are preferably centered on the locket 100 to facilitate the insertion of the lock 124 into the locking cavity 130. Preferably, when viewed from the rear of the locket 100, as seen in FIG. 6, the locking cavity 130 is generally rectangular in shape, having a width “w” and a height “h.” Preferably, the locking cavity 130 has a constant height and width throughout its length. Preferably, the width “w” of the locking cavity 130 is slightly larger than the width of the lock 124. Preferably, the height “h” of the locking cavity 130 is slightly smaller than that of the V-shaped portion 125 of the lock 124, when the upper biasing member 161 and the lower biasing member 162 are in their unbiased position. Preferably, the height “h” of the locking cavity 130 is slightly larger than that of the V-shaped portion 125 of the lock 124, when the upper biasing member 161 and the lower biasing member 162 are biased towards each other. The top of the locking cavity 130 is defined by an upper wall 166 and the bottom of the locking cavity 130 is defined by a lower wall 168.
Preferably, the locking cavity 130 is sized to frictionally retain the lock 124 therein. During insertion, the user will insert the tip 160 of the V-shaped portion 135 of the lock 124, through the opening 132 and into the locking cavity 130. To lock the locket 100 closed, the lock 124 is inserted, tip 160 first, into the locking cavity 130 until the compression tab 126 engages the hub 104, thereby preventing the lock 124 from being further inserted into the locking cavity 130.
Preferably, when the V-shaped portion 125 is inserted into the locking cavity 130, the upper biasing member 161 and the lower biasing member 162 are compressed towards each other by the upper wall 166 and the lower wall 168 of the locking cavity 130. This compression of the V-shaped portion 125 increases the frictional engagement between the lock 124 and the upper and lower wall 166, 168 of the locking cavity 130, thereby retaining the lock 124 within the locking cavity 130.
The locket 100 is unlocked by pressing the compression tab 126 towards the fifth panel 110e, thereby compressing the upper biasing member 161 towards the lower biasing member 162 and releasing the V-shaped portion 125 from the frictional engagement of the locking cavity 130. The lock 124 is released from the locking cavity 130 by pulling the compression tab 126 away from the hub 104, thereby withdrawing the lock 124 from the locking cavity 130.
In a second preferred embodiment of the locking mechanism shown in FIG. 7, lock retaining nubs 164a, 164b are disposed on the upper biasing member 161 and the lower biasing member 162 respectively. Cavity retaining nubs 166a, 166b are disposed on the upper wall and lower wall respectively. When the lock 124 is fully inserted into the locking cavity 130, the lock retaining nubs 164a, 164b are disposed closer to the front portion 116 of the hub 104 than the cavity retaining nubs 166a, 166b and frictionally retained there while the lock 124 is inserted in the locking cavity 130.
It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
