## Background
RELATED APPLICATIONS
This application claims priority to U.S. provisional patent application 61/763,251 filed Feb. 11, 2013 and titled “Ornamental Component With Gripping Element”, and also claims priority to European patent application EP 13154843 filed Feb. 11, 2013 and titled “Ornamental Component With Gripping Element”. The disclosure of each is incorporated herein in its entirety by reference.


FIELD
The present invention relates to an ornamental component for a bracelet or necklace, to a bracelet or necklace comprising such an ornamental component, to a method of manufacturing an ornamental component, and a tubular element for securing a gripping element inside a through hole of an ornamental component.
BACKGROUND
Jewelry, such as necklaces and bracelets, often consists of a plurality of freely movable ornamental components (e.g., beads) strung on an elongated member (e.g., chain, wire, or string). To prevent all the freely movable beads from grouping together at the bottom of the necklace or bracelet, an ornamental component provided with a stopping mechanism configured to grip the necklace or bracelet may be used. Such stopping mechanisms are known from the prior art in a variety of forms.
An example of a prior art variation of a stopping mechanism is disclosed in US 2003/0154742, in which a jewel is produced with an elastic body inside configured to provide a frictional force on an elongated member. A similar solution is disclosed in US 2002/0148250, in which the jewel itself is provided with a flexible resilient tube with an inside diameter slightly smaller than the outer diameter of an elongated member, as to fix the jewel on the elongated member.
Another prior art variation is disclosed in WO 2006/125155.
It may, however, be difficult to produce such prior art ornamental components. Additionally, the stopping mechanisms may be vulnerable to damage.
Thus, it remains a problem to provide a robust ornamental component provided with a stopping mechanism that can be easily manufactured.

DETAILED DESCRIPTION
According to a first aspect, the invention relates to an ornamental component for a bracelet and/or a necklace. The ornamental component has a through hole allowing the ornamental component to be strung on an elongated member of a bracelet and/or necklace, and the through hole defines a through hole axis. The ornamental component includes: (a) a self-supporting housing having a through hole comprising a first opening at a first side of the self-supporting housing and a second opening at a second side of the self-supporting housing; and (b) an insert assembly inserted in the through hole of the self-supporting housing. The insert assembly is assembled from a first tubular element having a through hole that forms at least a part of the through hole of the ornamental component and a gripping element for frictionally gripping a part of the bracelet and/or necklace, and the first tubular element is configured to secure the gripping element inside the through hole of the ornamental component.
Consequently, by using an insert assembly to provide an ornamental component with a gripping element, the production costs may be lowered. Additionally, by using a tubular element to secure the gripping element inside the self-supporting housing, the gripping element may be more efficiently protected from damage.
An ornamental component may be any component that can be strung on a bracelet and/or necklace for ornamental purposes such as a bead. An ornamental component according to the first aspect of the invention may be used to organize freely movable beads on a bracelet or necklace. For example, two ornamental components may be pulled to a desired position on an elongated member of a bracelet or necklace and released, whereby they resiliently grip the elongated member. Consequently (in this example), the bracelet or necklace is divided into three distinct zones for freely movable beads. This may be used to prevent all the freely movable beads from grouping together.
The self-supporting housing may constitute the outer surface of the ornamental component or may be covered with another layer or element constituting the outer surface of the ornamental component. The self-supporting housing may have any shape such as approximately spherical, cylindrical or cubical. The self-supporting housing has a structural strength allowing it to be securely handled during the manufacturing process of the ornamental component. The self-supporting housing may provide the primary structural strength of the ornamental component. The self-supporting housing may be made of metal, glass, wood, plastic or a combination thereof. The trough hole of the self-supporting housing may have a constant width or may have a varying width (measured in planes being perpendicular to the through hole axis). For example, the through hole of the self-supporting housing may be wider in the central part of self-supporting housing than at the first opening and the second opening. The inner surface of the through hole of the self-supporting housing may be spaced apart from the insert assembly by another element or a fluid e.g. air. At least a part of the self-supporting housing may be transparent or semi-transparent.
The individual element of the insert assembly may be permanently attached or non-permanently attached. The insert assembly may be inserted into the through hole of the housing through the first opening of the housing, i.e. the insert assembly may have a size and shape allowing it to be insertable through the first opening of the self-supporting housing.
The first tubular element may have any outer shape such as round or rectangular. Correspondingly, the through hole of the first tubular element may have any shape such as round or rectangular. The first tubular element may be integrally molded, i.e. made from a single mold. The first tubular element may be made of metal and/or plastic.
The gripping element may be made of a material configured to establish a high frictional connection with an elongated member of a bracelet and/or necklace, e.g. a chain, band, or strand of a necklace or bracelet. The gripping element may be made of a deformable material such as a silicone material.
In some embodiments, the gripping element is made of a first material and the first tubular element is made of a second material, wherein the coefficient of friction of the first material is higher than the coefficient of friction of the second material relative to sterling silver.
The coefficient of friction of the first material may be at least 10%, 20%, 40% or 60% higher than the coefficient of friction of the second material relative to sterling silver.
In some embodiments of the invention, the gripping element is positioned in a central part of the ornamental component and have a width along the through hole axis of less than 95%, 90%, 80%, 70%, 60% or 50% of the width of the self-supporting housing along the through hole axis.
Consequently, the gripping element is better protected. Thus, a more robust ornamental component is provided.
In some embodiments, the first tubular element comprises a first circumferential opening extending along the through hole axis, and the gripping element comprises a first gripping portion for frictionally gripping the elongated member of the bracelet and/or necklace, with the first gripping part extending through the first circumferential opening.
In some embodiments, the gripping element comprises a tubular portion, and the first gripping portion protrudes from an interior surface of the tubular portion. Further, the tubular portion of the gripping element surrounds a part of the first tubular element.
Consequently, the tubular element may in an efficient manner secure the gripping element inside the through hole of the ornamental component.
The entire gripping element may be integrally molded, i.e. made from a single mold.
In some embodiments, the first tubular element comprises a second circumferential opening extending along the through hole axis and the gripping element comprises a second gripping portion protruding from an interior surface of the tubular portion of the gripping element, with the second gripping portion extending through the second circumferential opening.
In some embodiments, the first tubular element comprises a third circumferential opening extending along the through hole axis and the gripping element comprises a third gripping portion protruding from an interior surface of the tubular portion of the gripping element, with the third gripping portion extending through the third circumferential opening.
In some embodiments, the first circumferential opening, the second circumferential opening and/or the third circumferential opening have a width along the through hole axis of less than 95%, 90%, 80%, 70%, 60% or 50% of the width of the first tubular element along the through hole axis.
In some embodiments, each of the first circumferential opening, the second circumferential opening and/or the third circumferential opening extends between 5% and 33% of the circumference of the first tubular element in a plane being perpendicular to the through hole axis.
In some embodiments, the first tubular element comprises a first portion and a second portion, wherein the second portion has a lower widest width than the widest width of the first portion. The tubular portion of the gripping element is arranged to fit snugly around the second portion of the first tubular element, and abut the first portion of the first tubular element whereby the gripping element is prevented from moving in a first direction along the through hole axis relative to the first tubular element.
In some embodiments, the first tubular element further comprises a third portion, and the second portion has a lower widest width than the widest width of the first portion and the third portion. The tubular portion of the gripping element further abuts the third portion of the first tubular element thereby preventing the gripping element from moving in any direction along the through hole axis relative to the first tubular element.
The widest width is measured in a plane being perpendicular to the through hole axis.
In some embodiments, the tubular portion of the gripping element has a widest width approximately equal to the widest width of the first portion and/or third portion of the first tubular element.
In some embodiments, the ornamental component further comprises a second tubular element, and the first tubular element is positioned inside the second tubular element.
This may make it easier to insert the insert assembly into the self-supporting housing. The second tubular element may additionally hide non-decorative elements of the ornamental component, when the self-supporting housing is transparent or semi-transparent.
The second tubular element may have a width along the through hole axis being approximately equal to the width of the self-supporting housing. The second tubular element may be fully inserted into the through hole of the self-supporting housing.
In some embodiments, the first tubular element of the insert assembly at a first end further comprises a collar, with the collar being positioned outside the self-supporting housing at the first opening of the self-supporting housing. The collar includes a surface abutting an outer surface of the self-supporting housing, thereby preventing the first tubular element of the insert assembly from moving in a first direction along the through hole axis relative to the ornamental component.
The outer surface may be an outer surface of the self-supporting housing. The collar may be an integral portion of the first tubular element or may be attached to the first tubular element.
In some embodiments, the ornamental component further comprises a locking element having a through hole wherein the locking element comprises an engagement portion positioned inside the self-supporting housing and a collar positioned outside the self-supporting housing at the second opening of the self-supporting housing. The engagement portion is attached to the first tubular element and the collar comprises a surface abutting an outer surface of the self-supporting housing, thereby preventing the first tubular element of the insert assembly from moving in a second direction along the through hole axis relative to the ornamental component.
Consequently, the insert assembly is in an effective manner secured to the self-supporting housing.
The outer surface may be an outer surface of the self-supporting housing.
The engagement portion and the collar of the locking element may be integrally formed. The locking element may be attached to the first tubular element by the use of glue or a mechanical locking mechanism.
In some embodiments, the engagement part of the locking element is inserted into the first tubular element whereby the through hole of the locking element and the through hole of the first tubular element together forms the through hole of the ornamental component.
In some embodiments, the engagement portion is attached to the first tubular element by a male/female locking mechanism, wherein the male part comprises a protruding portion and the female part comprises a recess and/or opening.
The engagement portion may be the male part and the first tubular element may be the female part, i.e. the engagement portion may comprise a protruding portion configured to engage with recess and/or opening in the first tubular element. Alternatively, the first tubular element may be the male part and the engagement portion may be the female part.
In some embodiments, the male/female locking mechanism is of the snap lock type wherein a translation and/or rotation from a free rotational orientation and/or position of the male and female part to a locked rotational orientation and/or position of the male and female part requires less force than a translation and/or rotation from a locked rotational orientation and/or position of the male and female part to a free rotational orientation and/or position of the male and female part.
This may be beneficial as the locking element and the first tubular element typically are permanently attached.
In some embodiments, the male/female locking mechanism may be of the rotational lock type, wherein the female part (the engagement portion or the first tubular element) comprises a recess and/or opening configured to allow the protruding portion of the male part to translate inside the recess and/or opening along the through hole axis when the locking element is in a free rotational orientation relative to the first tubular element, and to be prevented from moving in at least a first direction along the through hole axis when the locking element is in a locked position relative to the first tubular element and the locking element is in a locked rotational orientation relative to the first tubular element.
In some embodiments, the male part comprises a plurality of protruding portions and the female part comprises a plurality of recess and/or openings.
When the male/female locking mechanism is of the rotational type the locking element may be attached to the first tubular element by firstly rotationally orienting the locking element in the free rotational orientation relative to the first tubular element, next translating the first tubular element and/or the locking element along the through hole axis until the locking element is in the locked position relative to the first tubular element, and finally rotating the first tubular element and/or the locking element from the free rotational orientation to the locked rotational orientation.
The protruding portion of the male part and/or the recess and/or opening of the female part may be configured so that a rotation from the free rotational orientation to the locked rotational orientation requires less force than a rotation from the locked rotational orientation to the free rotational orientation.
In some embodiments, the male part (the engagement portion or the first tubular element) comprises a flexible member configured to deform from a first shape to a second shape when the male part comes into contact with the female part, and further to snap back into approximately the first shape when the flexible member is aligned with the recess and/or opening of the female part, whereby the flexible member engages with the recess and/or opening and locks the male part to the female part, allowing the locking element to be attached to the first tubular element by a pure translation between the two.
In some embodiments, the male part comprises two flexible members, and the female part comprises two recesses and/or openings.
The two flexible members may be arranged at opposite sides of the male part. Correspondingly, the two recesses and/or openings may be arranged at opposite sides of the female part.
In some embodiments, the ornamental component has a length along the through hole axis between 2 mm and 5 cm.
In some embodiments, the first tubular element comprises a fourth circumferential opening extending along the through hole axis and the gripping element comprises a fourth gripping portion protruding from an interior surface of the tubular portion of the gripping element, with the fourth gripping portion extending through the fourth circumferential opening.
According to a second aspect, the invention relates to a bracelet or a necklace having: an elongated member and a first ornamental component as disclosed in relation to the first aspect of the invention, strung on the elongated member. The first ornamental component is configured so that the gripping element resiliently grips the elongated member to fix the first ornamental component along the elongated member until a particular force is acting on the first ornamental component, whereby the first ornamental component can be moved along the elongated member.
The elongated member may be any elongated member suitable for jewelry such as a metal chain, leather string, a fabric string, or an anchor type chain.
In some embodiments, the particular force is higher than the maximum gravitational force gravity acting on the ornamental component.
In some embodiments, the bracelet or necklace further comprises at least one freely movable ornamental component strung on the elongated member.
In some embodiments, the bracelet or necklace further comprises a plurality of freely movable ornamental components strung on the elongated member.
In some embodiments, the bracelet or necklace further comprises a second ornamental component as disclosed in relation to the first aspect of the invention strung on the elongated member.

The first tubular element may have any outer shape such as round or rectangular. Correspondingly, the through hole of the first tubular element may have any shape such as round or rectangular. The first tubular element may be integrally molded (i.e., made from a single mold). The first tubular element may be made of metal and/or plastic.
The engagement portion of the locking element may be attached to the first tubular element by the use of an adhesive or a mechanical locking mechanism.
In some embodiments, the engagement portion is attached to the first tubular element by a male/female locking mechanism, wherein the male part comprises a protruding portion and the female part comprises a recess and/or opening.
The engagement portion may be the male part, and the first tubular element may be the female part (i.e., the engagement portion may comprise a protruding portion configured to engage with recess and/or opening in the first tubular element). Alternatively, the first tubular element may be the male part and the engagement portion may be the female part.
In some embodiments, the ornamental component further comprises a second tubular element, and the first tubular element and the engagement portion of the locking element are positioned inside the second tubular element.
This may make it easier to insert the insert assembly into the self-supporting housing. The second tubular element may additionally hide non-decorative elements of the ornamental component, when the self-supporting housing is transparent or semi-transparent. The second tubular element may additionally protect the attachment between the first tubular element and the engagement portion.
The second tubular element may have a length along the through hole axis being approximately equal to the length of the self-supporting housing. The second tubular element may be fully inserted into the through hole of the self-supporting housing. The engagement portion of the locking element may be fully inserted into the second tubular element.
In some embodiments, the male/female locking mechanism is of the snap lock type wherein a translation and/or rotation from a free rotational orientation and/or position of the male and female part, to a locked rotational orientation and/or position of the male and female part, requires less force than a translation and/or rotation from a locked rotational orientation and/or position of the male and female part to a free rotational orientation and/or position of the male and female part.
This may be beneficial as the locking element and the first tubular element typically are permanently attached.
In some embodiments, the male/female locking mechanism is of the rotational lock type, wherein the female part (the engagement portion or the first tubular element) comprises a recess and/or opening configured to allow the protruding portion of the male part to translate inside the recess and/or opening along the through hole axis when the locking element is in a free rotational orientation relative to the first tubular element, and to be prevented from moving in at least a first direction along the through hole axis when the locking element is in a locked position relative to the first tubular element and the locking element is in a locked rotational orientation relative to the first tubular element.
In some embodiments, the male part comprises a plurality of protruding portions and the female part comprises a plurality of recesses and/or openings.
When the male/female locking mechanism is of the rotational type, the locking element may be attached to the first tubular element by firstly rotationally orienting the locking element in the free rotational orientation relative to the first tubular element, next translating the first tubular element and/or the locking element along the through hole axis until the locking element is in the locked position relative to the first tubular element, and finally rotating the first tubular element and/or the locking element from the free rotational orientation to the locked rotational orientation.
The protruding portion of the male part and/or the recess and/or opening of the female part may be configured so that a rotation from the free rotational orientation to the locked rotational orientation requires less force than a rotation from the locked rotational orientation to the free rotational orientation.
In some embodiments, the male part (the engagement portion or the first tubular element) comprises a flexible member configured to deform from a first shape to a second shape when the male part comes into contact with the female part, and further to snap back into approximately the first shape when the flexible member is aligned with the recess and/or opening of the female part, whereby the flexible member engages with the recess and/or opening and locks the male part to the female part, allowing the locking element to be attached to the first tubular element by a pure translation between the two.
In some embodiments, the male part comprises two flexible members, and the female part comprises two recesses and/or openings.
The two flexible members may be arranged at opposite sides of the male part. Correspondingly, the two recesses and/or openings may be arranged at opposite sides of the female part.
In some embodiments, the engagement part of the locking element is inserted into the first tubular element whereby the through hole of the locking element and the through hole of the first tubular element together form the through hole of the ornamental component.
In some embodiments, the first tubular element at a first end further comprises a collar positioned outside the self-supporting housing at the first opening of the self-supporting housing. A surface abuts an outer surface of the self-supporting housing thereby preventing the first tubular element from moving in a first direction along the through hole axis relative to the ornamental component.
In some embodiments, the locking element further comprises a collar positioned outside the self-supporting housing at the second opening of the self-supporting housing. The collar includes a surface abutting an outer surface of the self-supporting housing thereby preventing the first tubular element from moving in a second direction along the through hole axis relative to the ornamental component.
In some embodiments, the first tubular element is part of an insert assembly inserted in the through hole of the self-supporting housing through the first opening of the self-supporting housing. The insert assembly is assembled from the first tubular element and a gripping element for frictionally gripping a part of the bracelet and/or necklace. The first tubular element is configured to secure the gripping element inside the through hole of the ornamental component.
According to a sixth aspect, the invention relates to a method for manufacturing an ornamental component having a through hole allowing the ornamental component to be strung on an elongated member of a bracelet and/or necklace, with the through hole defining a through hole axis. The method comprises the steps: (a) providing a self-supporting housing, having an through hole, wherein the through hole comprises a first opening at a first side of the self-supporting housing and a second opening at a second side of the self-supporting housing; (b) inserting through the first opening of the self-supporting housing a first tubular element having a through hole; (c) inserting through the second opening of the self-supporting housing a locking element having a through hole, the locking element comprising an engagement portion for being positioned inside the through hole of the self-supporting housing; and (d) attaching the engagement portion of the locking element to the first tubular element.
Consequently, by using two parts inserted from two sides of the ornamental component, the lining (the first tubular element and the locking element) may be attached to the bead without deforming it. This allows more complex insert elements to be used such as pre decorated linings and linings composed of a plurality of elements.
In some embodiments, the engagement portion is attached to the tubular element by a male/female locking mechanism.
In some embodiments, the method further comprises the step of inserting a second tubular element into the through hole of the self-supporting housing, either through the first opening or the second opening of the self-supporting housing, wherein the first tubular element and the engagement portion of the locking element are inserted into the second tubular element.
In some embodiments, the ornamental component is an ornamental component as disclosed in relation to the fifth aspect of the invention.

The ornamental component 100 comprises a self-supporting housing 101 having a through hole 150 comprising a first opening at a first side of the self-supporting housing 151 and a second opening at a second side of the self-supporting housing 152, and an insert assembly 102 103 inserted in the through hole 150 of the self-supporting housing 101. The insert assembly 102 103 comprises a first tubular element 102 and a gripping element 103 (only schematically shown). The gripping element 103 is configured for frictionally gripping a part of a bracelet and/or necklace. The first tubular element 102 has a through hole 140 which in this embodiment forms the full through hole of the ornamental component 100. However, in other embodiments of the invention the through hole of the first tubular element 140 forms only a limited part of the through hole of the ornamental component 100. The through hole of the ornamental component allows it to be strung on an elongated member of a bracelet and/or necklace. The trough hole of the self-supporting housing 150 has a varying width (measured in planes being perpendicular to the through hole axis), i.e. the through hole of the self-supporting housing 150 is wider in the central part of self-supporting housing than at the first opening 151 and the second opening 152. The inner surface of the through hole of the self-supporting housing 150 is spaced apart from the insert assembly 102 103 by a fluid e.g. air. The first tubular element 102 is configured to secure the gripping element 103 inside the through hole 150 of the ornamental component. This may be achieved by attaching the gripping element 103 to the first tubular element 102 e.g. by adhering the two elements together or by positioning the gripping element 103 in a recess of the first tubular element 102 e.g. as shown in FIG. 2. The first tubular element 102 may alternatively secure the gripping element 103 inside the through hole 150 of the ornamental component by having a part of the gripping element wrapped around its outer surface as disclosed in relation to FIGS. 3-5.

The locking element 306 has a through hole, and comprises an engagement part 361 for engaging with the insert assembly 370 and a collar 362 for being positioned outside the self-supporting housing 301. The ornamental component 300 may be manufactured/assembled by firstly assembling the insert assembly 370. The insert assembly 370 may be assembled by arranging the gripping element 303 around the second portion 322 of the first tubular element 302, so that gripping portions of the gripping element 303 (not shown) extends through circumferential openings of the first tubular element 302. Next, the insert assembly 370 may be inserted into the second tubular element 305. Then the insert assembly 370 with the second tubular element may be inserted into a through hole of the self-supporting housing 350 in a manner so that the collar 324 is positioned outside the self-supporting housing 301. The second tubular element 305 may alternatively be inserted into the through hole of the self-supporting housing 350 before the insert assembly 370 is inserted. The insert assembly 370 and/or the second tubular element 305 may be inserted into the through hole of the self-supporting housing 350 through a first opening 351. The insert assembly 370 and/or the second tubular element 305 may alternatively be inserted into the through hole of the self-supporting housing 350 before the self-supporting housing 301 is fully formed/assembled e.g. the insert assembly 370 and/or the second tubular element may be inserted into a first half of the self supporting housing 301, whereafter a second half of the self-supporting housing 301 is attached to the first half, thereby forming the finished self-supporting housing 301 with the insert assembly 370 inserted in its through hole 350. Finally, the locking element 306 is inserted in a second opening 352 of the through hole of the self-supporting housing 350, and the engagement part 361 is attached to the first tubular element 302.

FIG. 10a shows a top view, FIG. 10b shows a side view, FIG. 10c shows a front view and FIG. 10d shows a back view. The first tubular element 1002 has a through hole 1074 and comprises a collar 1024, a first portion 1021, a second portion 1022, and a third portion 1023. The collar 1024, the first portion 1021, and the second portion 1022 may be identical to the corresponding parts of the first tubular element shown in FIG. 4a-d. The third portion 1023 comprises mechanical locking means in the form of a female part of male/female locking mechanism 1075 1076. The female part 1075 1076 comprises a first opening 1075 and a second opening 1076 extending along the through hole axis.

FIGS. 11a-d show a locking element 1106 according to an embodiment of the present invention. FIG. 11a shows a top view, FIG. 11b shows a front view and FIG. 11c shows a back view. The locking element 1106 has a through hole 1165 and comprises a collar 1162 and an engagement portion 1161. The collar 1162 may be identical to the collar of the locking element shown in FIG. 8. The engagement portion 1161 comprises mechanical locking means in the form of the male part 1166 1167 of a male/female locking mechanism. The male part 1166 1167 comprises a first flexible member 1166 and a second flexible member 1167. The first and second flexible member 1166 1167 each comprises a protruding portion 1168 1169. The male/female locking mechanisms shown in FIGS. 10a-c and FIGS. 11a-c are configured to function together, thus the protruding portions 1168 1169 are configured to fit the openings 1075 1076. The locking element 1106 may be attached to the first tubular element 1002 by moving the two elements together until the male part comes into contact with the female part, whereby the first and second flexible member 1166 1167 are deformed from a first shape to a second shape, i.e. the first and second flexible member 1166 1167 are both progressively bent inwards. This is a result of an interaction between the rounded front surface of the two flexible members 1166 1167 and the rim 1077 of the through hole 1074 of the first tubular element 1002. When the two flexible members 1166 1667 are aligned with the two openings 1075 1076 of the first tubular element 1002, the two flexible members 1166 1667 snap back into approximately the first shape, whereby the protruding portions of the two flexible members 1168 1669 engages with the openings 1075 1076 and locks the locking element 1106 to the first tubular element 1002. Thus, the locking element 1106 can be attached to the first tubular element 1002 by a pure translation between the two. The male/female locking mechanism 1075 1076 1166 1167 is of the snap lock type wherein a translation from a free position of the male and female part, to a locked position of the male and female part, requires less force than a translation from a locked position of the male and female part to a free position of the male and female part. This is a result of the special shape of the protruding portions 1168 1669 and the openings 1075 1076. This may be beneficial as the locking element 1106 and the first tubular element 1002 typically are permanently attached.
FIG. 12 shows a central cross-section of a fully assembled ornamental component comprising a first tubular element and a locking element as disclosed in relation to FIGS. 10a-d and FIGS. 11a-c according to an embodiment of the present invention.
