Finger rings include round bands that may be worn as engagement rings, wedding bands, ornamental jewelry, or other purposes. Finger rings may be made of various materials and have various tensile strengths and shear strengths.
The accompanying drawings illustrate various implementations of the principles described herein and are a part of the specification. The illustrated implementations are merely examples and do not limit the scope of the claims.
Throughout the drawings, identical reference numbers designate similar, but not necessarily identical, elements.
A ring may be made to break or otherwise become separated upon impact and applied pressure. The following relates to a ring having at least one key member that serves as the weakest link and that can break under force or pressure and thereby allow the ring to become separated or otherwise become loose. While reference is made to a ring, application of the invention pertains to other ring-like members, including bracelets, earrings, and other accessories.
An example of a locking ring includes a first annular band portion and a second annular band portion. The locking ring includes a first and second cutout on at least one end of the respective first and second annular band portions. The ring configuration is made by bringing the first and second annular band portions together. A key member is to be inserted within the first and second cutout to thereby lock the first and second annular band portions into a ring configuration to be worn on a finger. The key member is to be released when the ring configuration is under a force to thereby allow the first and second annular band portions to be unlocked.
Another example of a locking ring includes a circular band configured to be worn on a finger. A cutout in the band extends at least partially within a depth of the band. A key member is to be inserted within the cutout, the key member to be released when the ring configuration experiences a threshold force.
Another example of a locking ring includes a first annular band portion and a second annular band portion. The first and second annular band portions are symmetrical to each other. A first and second cutout is located on each end of the respective first and second annular band portions. Contact and alignment of the first and second annular band portions form the ring configuration. The alignment brings the first and second cutouts together to define bowtie shapes located on diametrically opposing sides of the ring configuration. A key member is inserted within each of the first and second cutouts to thereby lock the first and second annular band portions into the ring configuration. The key member comprises a material that breaks under less force than the first and second annular band portions, the force to thereby allow the first and second annular band portions to be unlocked.
The release of a finger from the ring configuration is advantageous, for example, when a finger gets caught in moving machinery or a heavy object. Also, the key member of the ring absorbs impact that would otherwise be transmitted to a finger through the annular band portions of the ring.
Turning to
While reference is made throughout the description to two key members 110-1, -2, examples include only a single a key member or multiple key members. For example, the first 102 and second annular band portions 104 may be attached on first ends by a hinge or other locking mechanism. On second ends, the first 102 and second annular band portions 104 may include cutouts that define a bowtie shape in which a key member 110 (see
Outer ends of each band portion 102, 104 are flat so that they lay flush together when band portions 102, 104 are attached together. Outer ends further include cutouts 108-1, -2, -3, -4 (see
The cutouts 108-1, -2, -3, -4 may extend equal depths or different depths in the material of the respective first 102 and second band portions 104. The cutouts 108-1, -2, -3, -4 may be provided by material being omitted or material that is carved out or otherwise removed from the outer ends of the band portions 102, 104. Each cutout 108-1, -2, -3, -4 may be a same or different shape. As shown, cutouts 108-1, -2, -3, -4 are the same such that when ends of band portions 102, 104 are put together, cuts or slits 120 are formed, and the cutouts 108-1, -2, -3, -4 define a shape that is symmetrical along a centerline or transverse axis of the ring 100, such as an axis that is perpendicular to a central axis of the circular band. The cutouts 108-1, -2, -3, -4 may also be described as being symmetrical about the line formed by the cut or slit 120 where ends are meeting flush together.
In another example, the cutouts 108-1, -2, -3, -4 are asymmetrical, defining a bow tie shape that is positioned off center from the line formed by ends of the first 102 and second semi-annular band portions 104. In another example, the cutouts 108-1, -2, -3, -4 comprise different shapes from each other. For example, at least one cutout of the cutouts 108-1-2, -3, -4 may comprise a shape that is not a half bowtie shape, such as a half circle or half arrow shape. Other half shapes or shapes are anticipated for at least one of the cutouts 108-1, -2, -3, -4.
As shown, ends of the cutouts 108-1, -2, -3, -4 are wider than a central location of the cutouts 108-1, -2, -3, -4. The cutouts are angled indentations that taper outward from the free ends of the respective band portions 102, 104. The edges of the first 102 and second semi-annular bands 104 meet flush together to form the circular band.
The cutouts 108-1, -2, -3, -4 may have a depth that is less than half, half, or more than half the depth of the first 102 and second semi-annular bands 104. In an example, the cutouts 108-1, -2, -3, -4 extend all the way through the first 102 and second semi-annular bands 104. In another example, the cutouts 108-1, -2, -3, -4 extend different depths from each other. For example, cutout 108-1, may extend partially through the first band 102 while cutout 108-2 extends all the way through the second band 104. In an example, the cutouts 108-1, -2, -3, -4 each have a depth that is less than a length of the key members 110-1, -2. In another example, the cutouts 108-1, -2, -3, -4 each have a depth that is equal to or greater than a length of the key members 110-1, -2.
A key member 110 is shown in
A first half of the bowtie of the key member 110-1 is inserted into one of the cutouts 108-1, -3 on the end of the first semi-annular band portion. The second half of the bowtie 110-1 is inserted into one of the cutouts 108-2, -4 on the end of the second semi-annular band portion 104. The key member 110-1, -2 is curved so as to follow the contours and curvature of the first 102 and second semi-annular band portions 104. In other words, the radius of curvature of the key members 110-1, -2 is the same as the radius of curvature of the first 102 and second semi-annular band portions 104. The key member 110-1, -2 is to lay flush with the first 102 and second semi-annular band portions 104 such that an inner facing surface of the key member 110 and an inner facing surface of the first 102 and second semi-annular band portions 104 is smooth. Each key member 110-1, -2 may be molded separately before being inserted into the respective cutouts 108-1, -2, -3, -4. The cross-sectional area and shape of the key members 110-1, -2 may be adjusted based on the desired design and load resisting capacity.
Each end of the first and second band portions 102, 104 have a cutout 106-1, -2, -3, -4. Two key members 110-1, -2 secure the first and second band portions together when inserted within the respective cutouts 106-1, -2, -3, -4. The key members 110-1, -2 lay diametrically opposed along a circumferential perimeter of the first 102 and second band portions 104 when inserted within the cutouts 108-1, -2, -3, -4. In another example, the key members 110-1, -2 are adjacent to each other. For example, the key members 110-1, -2 may be at a 90 degree angle from each other along the circumferential perimeter of the ring 100 and with respect to a center of the ring 100.
The first 102 and second band portions 104 and key members 110-1, -2 may comprise a metal, plastic, or combination thereof. In an example, the material may be one or more of gold, silver, platinum, tungsten, or metal alloy. In an example, the material comprises one or more of plastic or metal or combination thereof. In another example, the material may include a polymer comprising plastic and rubber. In an example, the key members 110-1, -2 are made of different material than the first 102 and second band portions 104.
The key members 110-1, -2 may be attached to the first 102 and second band portions 104 by a friction fit, a bond material, applied heat, silver or tin alloy solder, or any material that is weaker than the key members 110-1, -2 or the first 102 and second band portions 104. In an example, the bond is a silicon based adhesive. The material may be weaker than both the key members 110-1, -2 and the first 102 and second band portions. In an example, the material is plastic. During use, the ring 100 may slide on a finger and receive normal wear and tear without the key members 110-1, -2 breaking.
The material of the key members 110-1, -2 is designed to break apart under a force. A threshold force that breaks the material may be less than a force that would break the material of the first and second band portions 102, 104. In an example, the tensile strength of the key members 110-1, -2 is less than the first 102 and second band portions 104. In another example, the shear strength of the key members 110-1, -2 is less than the first 102 and second band portions 104. In another example, the material of the key members 110-1, -2 will break at 18 lbs. In another example, the material will break at 18 lbs to 20 lbs, 20 lbs to 22 lbs, or 22 lbs to 24 lbs. The material may be designed to withstand a pressure that protects damage to fingers. In an example, each key member 110-1, -2 includes different properties such that a first key member 110-1 breaks before a second key member -2. The properties may be different in at least one of material, tensile strength, and shear strength.
Although the key member is shown in a bowtie shape, other shapes are anticipated, including polygons, diamond shape, a figure eight or infinity symbol, as well as other shapes.
Particularly, each cutout 208-1, -2, -3, -4 includes a recessed indentation. One indentation starts from a bottom end surface while the corresponding indentation starts from a top end surface. Cutouts 208-1, -3 on band portion 202 include rounded indentations that have a consistent depth in the material of the band portion 202 starting from a top, or outer facing surface of the band portion 202. Cutouts 208-2, -4 on band portion 204 include rounded indentations that have a consistent depth in the material of the band portion 204 starting from a bottom, or inner facing surface of the band portion 204. Bottom facing cutouts 208-2, -4 slide over surfaces of top facing surfaces 208-1, -3 with a friction fit or otherwise smooth fit with surfaces being flush. A bond material, such as a silicon based adhesive is used to secure the two ends together.
Because the cutouts 208-1, -2, -3, -4 are thinner relative to the remainder of the band portions 202, 204, the cutouts 208-1, -2, -3, -4 will break apart before the rest of the band portions 202, 204.
The preceding description has been presented to illustrate and describe examples of the principles described. This description is not intended to be exhaustive or to limit these principles to any precise form disclosed. Many modifications and variations are possible in light of the above teaching.
