LOW-PROFILE EXPANDABLE RING STRUCTURE

Abstract

A low-profile expandable ring structure comprising a plurality of coupled blocks each maintaining a degree of translational movement with respect to each other. Each block has one or more protruding tubes on the front side, which are inserted into openings of the adjacent block. A tensioned spring is passed through the internal channel of each block, which maintains the ring structure in a closed appearance but allows expansion of the ring structure through the translational movement of the blocks. This nature allows the expandable ring structure to be comfortable for the wearer.

DETAILED DESCRIPTION

[0019] FIGS. 2-5 depict a single block 100 according to the main embodiment of the solution.

[0020] Each block generally comprises body 100, tube 101, stopper 102, groove 103, and channel 105.

[0021] Each channel is curving downward. Each stopper 102 is shorter than each groove 103 to allow the translational movement of the blocks, which form the low-profile expandable ring structure.

[0022] Body 100 is generally prism shaped with a hollow center to reduce the weight of the body 100 and for ease of manufacturing, according to a preferred embodiment of the invention. As shown in FIG. 4, a bottom surface of body 100 is curved. Thus, when a plurality of blocks is joined together, the plurality forms a smooth ring structure, especially when in the collapsed state, due to the curvature of the bottom surface of body 100. The top surface of body 100 is wider than the bottom surface otherwise sizable gaps, and other internal components, would be visible in the expandable ring structure. The opposing side surfaces of body 100 preferably have the same decoration and construction as depicted in FIGS. 4 and 6.

[0023] In the main embodiment, each block has one or more downward curved tubes 101 extending from the front surface of each block as depicted in FIGS. 1 and 2. Each curved tube 101 has a cutout on the bottom surface for a stopper connection as depicted in FIGS. 5 and 6. Each tube 101 has a curved internal channel that extends through an opening in the back surface of the blocks as depicted in FIGS. 1 and 2.

[0024] A stopper 102 is provided in the ring structure that is coupled beneath each curved tube 101 once pairs of blocks are connected as depicted in FIG. 7. This is done by “squeezing” the stopper 102 into the curved cutout, a groove 103, located beneath the bottom surface of the curved tube protrusion as seen in FIG. 8. This is done to prevent separation of the blocks.

[0025] FIGS. 7 and 8 show numerous blocks joined together with one spring passing through curved channel 105 of the blocks of the claimed ring structure. FIGS. 7 and 8 also show how the bottom curved surfaces of the blocks form the expandable ring structure and have a smooth curved interior, similar to a standard ring. One or several springs 104 may also be utilized, depending upon the size of expandable ring structure. Application of two or more springs has the advantage that the force from springs 104 is more evenly distributed across the piece.

[0026] The groove 103 is longer than the stopper 102 as seen in FIGS. 5 and 6, which is what allows translational movement of each relative block.

[0027] A spring 104 is provided in the ring structure, which goes through an opening 105 of the tubes 101 as displayed in FIG. 3. The spring 104 provides a compressive force to maintain a “solid-like” closed appearance unless stretched to accommodate wearer's size. Once taken off, the expandable ring structure reverts to its original size.

[0028] FIGS. 7 and 8 depict how adjacent blocks are coupled to each other in the expandable ring structure where a tube 101 from a block is inserted into a channel of an adjacent block through the rear. A stopper 102 is coupled beneath each curved tube 101 once pairs of blocks are connected.

[0029] FIG. 9 displays a view of the completed expandable ring structure, according to the preferable embodiment. FIG. 9 shows the low-profile expandable ring structure comprising of a singular row of the blocks and showing the stoppers 102 located on the inner part of a ring.

[0030] The internal surface of the claimed expandable ring structure forms a ring and would not feel any different to a user than a standard ring during wear. In fact, the expandable ring structure is more comfortable because it can be adjusted to the user to accommodate swelling, aging, etc. as well as any possible expansion or contraction of the components of the expandable ring structure due to heat, humidity, wear, etc.

[0031] To form the claimed expandable ring structure, the following process is preferably utilized. First, all of the blocks, except the first and the last, are joined together using the tubes 101. The tubes 101 from a block are inserted into the channels of an adjacent block through the rear. Then, a stopper 102 is coupled beneath each curved tube once a pair of blocks are connected by “squeezing” the stopper into the curved cutout beneath the bottom surface of the curved tube protrusion. One end of the spring(s) 104 is fixed to the first block, passed through all spring channels, and then stretched and secured to the interior of the last block. The first and last block are then permanently joined together by the tube 101.

[0032] Blocks are preferably formed as a unitary piece by casting in a mold. When used for jewelry, the blocks are preferably formed from a precious or semi-precious metal such as silver, gold, platinum, titanium, etc. However, other metals, such as steel, may be used and then provided with a coating or plating of another metal, such as gold.

[0033] FIGS. 3-5 display the opening for the spring 105. FIG. 10 depicts a second embodiment of the blocks of the claimed ring structure comprising of a double row of the blocks, displaying the location of the stoppers 102 on the inner part of the ring. In this embodiment, the size, shape, and curvature of body 100 is the same as those depicted in FIGS. 1-9.

[0034] Another embodiment of the claimed low-profile expandable ring structure shown in FIG. 10 is displayed in FIG. 11, showing an alternate example of the double row of the blocks in the ring structure with the double row of the stoppers 102. FIG. 12 depicts, in turn, the multiple rows of the blocks of the low-profile expandable ring structure showing location of the stoppers 102.

[0035] FIG. 13 displays another embodiment of the low-profile expandable ring, showing the multiple rows of the block and location of the stoppers 102.

[0036] The present solution described above is not intended to be limited to any particulars or embodiments or any particular embodiment, but instead it is construed to provide the broadest possible interpretation of claims in view of prior art and, therefore, to effectively provide the possible broadest scope of protection.
