DETAILED DESCRIPTION OF EMBODIMENTS

(12) In the following description, reference is made to the accompanying figures, which show, by way of illustration, how the disclosure may be practiced. Turning to FIGS. 1A-C and FIGS. 2A-B, FIGS. 1A-C show part (a friction element) of an ornament 1 of an embodiment of the first aspect of the disclosure. FIGS. 1A and 1B show perspective views, and FIG. 1C shows an end/top view. In the following, FIGS. 1A-C are explained in relation to a first friction element, denoted 100, but it is to be understood that the same description may apply to a second friction element, denoted 200.

(13) FIGS. 2A-B show the first friction element 100 and the second friction element 200 positioned on an elongated member 300. These figures illustrate how the friction elements 100, 200 may be arranged on the elongated member 300 when the ornament 1 is strung on the elongated member 300. Besides the friction elements 100, 200, nothing else of the ornament is shown in those figures.

(14) The first friction element 100 comprises a first retaining part 110, which is adapted to be arranged in a cavity of an ornament 1 as shown in e.g. FIGS. 7A-B when the ornament 1 is in an assembled configuration, wherein the first friction element 100 is attached to the ornament 1.

(15) The first friction element 100 further comprises a first friction part 120 attached to the first retaining part 110. The first friction part 120 comprises a first gripping surface 121 for frictionally gripping a surface 321 of an elongated member (as shown in FIG. 3A) when the ornament 1 in the assembled configuration is strung on the elongated member 300, whereby the ornament 1, when the ornament is in the assembled configuration is strung on the elongated member 300, can be releasably secured in a first location on the elongated member 300 and be relocated by a sliding movement along the elongated member 300 to be releasably secured at a second location on the elongated member 300.

(16) The first friction part 120 in an un-deformed state, and the first retaining part 110 in an un-deformed state, have different material and/or mechanical properties in the unassembled configuration of the ornament. The first friction part 120 has a first hardness shore A, and the first retaining part 110 has a second, higher hardness shore A. The difference in hardness acts to prevent the first friction element 100 from being detached from a shell of the ornament during the sliding movement.

(17) In embodiments, the second hardness shore A of the retaining part 110 is at approximately 266 percent higher than the first hardness shore A of the friction part 120. The first hardness of the friction part 120 may be approximately 30 shore A, and the second hardness of the retaining part 110 may be approximately 80 shore A.

(18) The first friction part 120 of the first friction element 100 comprises a first protrusion 140 which extends from the first friction part 120. The first protrusion 140 has a first protrusion gripping surface 141 for frictionally gripping a first surface area 341 of the elongated member 300 when the ornament 1 in the assembled configuration is strung on the elongated member as seen in FIGS. 2A-B.

(19) The first protrusion gripping surface 141 has a concave shape (in a plane being perpendicular to a longitudinal axis L extending in the axial direction) so as to match the surface of the elongated member 300. When the ornament 1 is in the assembled configuration, the longitudinal axis L is parallel with the through hole axis A of the ornament. The first protrusion gripping surface 141 is a smooth even surface.

(20) The first protrusion 140 further comprises two, opposite, side surfaces 142, 143. The side surfaces 142, 143 are arranged at an angle with respect to each other. The angle may be approximately 90 degrees. These side surfaces assist in minimizing sharp angles that could potentially shear off/break off during use.

(21) As seen in FIG. 1C, the first friction element 100 comprises a first wing 101 and a second, opposite, wing 102. The first wing 101 and the second wing 102 extend away from each other in a direction perpendicular to the longitudinal axis L. The first and second wings 101, 102 are in this embodiment formed partly by the retaining part 110 and partly by the friction part 120.

(22) The friction element 100 defines a height H (extending in the radial direction of the ornament when the ornament is in the assembled configuration as seen in FIG. 7A) and a width W along a reference axis being perpendicular to the longitudinal axis L. The maximum width of the friction part 120 is larger than the maximum width of the first protrusion 140. The maximum width of the retaining part 110 is larger than the maximum width of the first protrusion 140. The first protrusion 140 extends along the longitudinal axis L defining a depth of the first protrusion.

(23) The depth is approximately 2.4 mm. The maximum length of the first friction element is approximately 7.8 mm. The maximum width of the friction element is approximately 3.9 mm. The maximum height of the friction element is approximately 2.7 mm. The maximum height of the retaining part is approximately 1 mm.

(24) The first protrusion 140 and the first friction part 120 may be integrally formed. Thus, the first protrusion 140 may comprise the same material as the first friction part 120 and thereby has the same first hardness shore A.

(25) The first friction part 120 further comprises a second protrusion 150. The second protrusion 150 is arranged at a distance to the first protrusion 140 along the longitudinal axis L. The first gripping surface 121 is visible in the distance between the first and second protrusion and thus separates the first and second protrusions in the longitudinal direction L.

(26) The second protrusion 150 extends from the first friction part 120 and has a second protrusion gripping surface 151 for frictionally gripping a second surface area 351 of the elongated member when the ornament in the assembled configuration is strung on the elongated member (as seen in FIG. 3B). The second surface area 351 is different from, and arranged at a distance to, the first surface area 341, so that the ornament may be releasably secured to parts of the elongated member 300 having different widths, e.g. when the elongated member comprises a band 301 as shown in FIGS. 3A-C.

(27) The length LB of the band 301 is less than the distance between the first and second protrusions 140, 150, which enables the ornament 1 via the first friction element 100 to grip around the band on the elongated member 300. The first protrusion gripping surface 141 grips the elongated member 300 at the first surface area 341 of the elongated member 300 on one side of the band 301, and the second protrusion gripping surface 151 grips the other side of the elongated member 300 at the second surface area 351 of the elongated member on the other side of the band 301. Depending on the diameter DB of the band 301, the first gripping surface 121 may also grip the surface 321 of the elongated member, in this case the surface of the band 301.

(28) The second protrusion gripping surface 151 has a concave shape (in a plane being perpendicular to a longitudinal axis L extending in the axial direction) so as to match the surface of the elongated member 300. The second protrusion gripping surface 151 may be a smooth even surface. Likewise, the gripping surface 121 may be a smooth even surface.

(29) The second protrusion 150 further comprises two, opposite side surfaces 152, 153. The side surfaces 152, 153 are arranged at an angle with respect to each other. The angle is approximately 90 degrees.

(30) The second protrusion 150 and the first friction part 120 are integrally formed. Thus the second protrusion 150 comprises the same material as the first friction part 120 and thereby has the same first hardness shore A.

(31) When the ornament 1 in the assembled configuration is strung on the elongated member 300, the first and second protrusion gripping surfaces 141, 151 are substantially continuously in contact with the surface of the elongated member before, during and after the sliding movement of the ornament 1.

(32) As seen in FIGS. 2A-B, the ornament 1 further comprises a second friction element 200.

(33) The ornament 1 is able to be arranged in an un-assembled configuration, in which the first and second friction elements 100, 200 are un-attached to or detached from the shell of the ornament, and an assembled configuration (as seen in FIGS. 7A-B), in which the first and second friction elements 100, 200 are attached to the shell.

(34) The above described features relating to the first friction element 100 may also apply to the second friction element 200. But for clarification in relation to the figures, the second friction element 200 is shortly described in the following.

(35) The second friction element 200 comprises a second retaining part 210, which is arranged to be gripped by a locking element 560 (as shown in FIGS. 6A-B) when the ornament 1 is in the assembled configuration. The second friction element 200 further comprises a second friction part 220 attached to the second retaining part 210 and comprising a third gripping surface 240 for frictionally gripping a surface of the elongated member 300 when the ornament in the assembled configuration is strung on the elongated member.

(36) The second friction part 220 has a first hardness shore A, and the second retaining part 210 has a second, higher hardness shore A. The second hardness shore A of the second retaining part 210 may be 266 percent of the first hardness shore A of the second friction part 220. In embodiments, the first hardness of the second friction part 220 may be approximately 30 shore A, and the second hardness of the second retaining part 210 may be approximately 80 shore A.

(37) The second friction part 220 comprises a third protrusion 240. The third protrusion 240 extends from the second friction part 220. The third protrusion 240 has a third protrusion gripping surface 241 for frictionally gripping a third surface area 342 of the elongated member 300 when the ornament 1 in the assembled configuration is strung on the elongated member 300 as seen in FIGS. 2A-B.

(38) The third protrusion gripping surface 241 has a concave shape so as to match the surface of the elongated member 300. The third protrusion gripping surface 241 may be a smooth even surface. The third protrusion 240 further comprises two, opposite, side surfaces 242, 243, which are arranged at an angle with respect to each other. The angle is approximately 90 degrees.

(39) As seen in FIG. 6B, the second friction element 200 comprises a first wing 201 and a second, opposite, wing 202, the wings 201, 202 extending away from each other. The first and second wings 201, 202 are formed partly by the second retaining part 210 and partly by the second friction part 220.

(40) The dimensions of the second friction element 200 correspond in this embodiment to the dimensions of the first friction element 100 as described above.

(41) The third protrusion 240 and the second friction part 220 may be integrally formed. Thus the third protrusion 240 may comprise the same material as the second friction part 120 and thereby has the same first hardness shore A.

(42) The second friction part 220 further comprises a fourth protrusion 250. The fourth protrusion 250 is arranged at a distance to the third protrusion 240 along the longitudinal axis L. The second gripping surface 221 is visible in the distance between the first and second protrusion and thus separates the first and second protrusions in the longitudinal direction L.

(43) The fourth protrusion 250 extends from the second friction part 220 and has a fourth protrusion gripping surface 252 for frictionally gripping a fourth surface area 352 of the elongated member when the ornament in the assembled configuration is strung on the elongated member (as seen in FIG. 3B). The fourth surface area 352 is different from, and arranged at a distance to, the third surface area 342.

(44) The length of the band 301 is less than the distance between the third and fourth protrusions 240, 250. The third protrusion gripping surface 241 grips the elongated member 300 at the third surface area 342 of the elongated member on one side of the band 301, and the fourth protrusion gripping surface 251 grips the other side of the elongated member 300 at the fourth surface area 352 of the elongated member on the other side of the band 301.

(45) As seen in FIGS. 3B-C the first friction element 100 is positioned on the side of the elongated member 300 opposite from the second friction element 200 when the ornament is strung on the elongated member 300. This ensures that the entire shell of the ornament 1 is positioned at a distance to the elongated member 300, so that when the ornament 1 by a sliding motion is moved along the elongated member 300, the hard shell will have limited, preferably no, contact with the elongated member. This ensures a prolonged lifespan of the elongated member 300, since the shell will contribute minimally to the wear and tear of the elongated member 300.

(46) The fourth protrusion gripping surface 251 has a concave shape to match the surface of the elongated member 300. The fourth protrusion gripping surface 251 may be a smooth even surface. Likewise, the second gripping surface 221 may be a smooth even surface.

(47) The fourth protrusion 250 further comprises two, opposite, side surfaces 252, 253. The side surfaces 252, 253 are arranged at an angle with respect to each other. The angle is approximately 90 degrees. The fourth protrusion 250 and the second friction part 220 may be integrally formed. Thus the fourth protrusion 250 may comprise the same material as the second friction part 220 and thereby has the same first hardness shore A.

(48) When the ornament 1 in the assembled configuration is strung on the elongated member 300, the third and fourth protrusion gripping surfaces 241, 251 are substantially continuously in contact with the surface of the elongated member 300 before, during and after the sliding movement of the ornament 1.

(49) As seen in FIGS. 3B-C, depending on the width of the wide part i.e. the band 301 of the elongated member, the first gripping surface 121 may abut the band 301, if the distance from the surface of the elongated member 300 to the surface of the band 301 is approximately equal to or larger than the height of the highest of the protrusions (e.g. 140, 150) of the friction element 100.

(50) When the ornament 1 in the assembled configuration is strung on the elongated member 300, the first protrusion 140 extends towards the third protrusion 240 and, vice versa, the first and third protrusion gripping surfaces 141, 241 grip each side of the elongated member 300. Furthermore, the second protrusion 150 extends towards the fourth protrusion 250 and, vice versa, the second and fourth protrusion gripping surfaces 151, 251 grip each side of the elongated member 300.

(51) Turning to FIGS. 7A-C, which show the ornament 1 for being strung on the elongated member 300, which is a string formed of metal strands, of a bracelet 800 shown in FIG. 10. FIGS. 7A-B show the ornament 1 in an assembled configuration and in an open state. FIG. 7C shows the ornament in an assembled configuration and in a closed state.

(52) The ornament 1 comprises a shell (here shown in two parts or half shells 401, 501) having a cavity 460. The ornament 1 further comprises a first friction element 100. The ornament 1 is able to be arranged in an un-assembled configuration, in which the first friction element 100 is un-attached to the shell part 401, and an assembled configuration, in which the first friction element 100 is at least partly located in the cavity 460 so as to be attached to the shell part 401.

(53) The ornament 1 further comprises a locking element 560 arranged inside the shell 501 and a second friction element 200, the ornament 1 being able to be arranged in another un-assembled configuration, in which the second friction element 200 is un-attached to the shell, and another assembled configuration, in which the second friction element 200 is attached to the shell 501 via the locking element 560.

(54) As seen in FIG. 7C, the ornament 1 further comprises a through hole 9, the through hole defining in the assembled configuration an open passageway extending from one opening 91 of the shell and, through the shell and to another, opposite opening 92 of the shell, the through hole allowing the ornament 1 to wreathe the elongated member 300 of the bracelet when the ornament 1 is strung on the bracelet. The through hole 9 is defined by the first protrusion gripping surface 141, the second protrusion gripping surface 151, the third protrusion gripping surface 241, the fourth protrusion gripping surface 251, the shell 401, 501 as well as by the two openings 91, 92 (illustrated in FIGS. 4B and 5B).

(55) The ornament 1 is a clip type ornament 1. The ornament 1 comprises two shell parts 401, 501, that are hinged to each other by means of a well-known type hinge 8, which could be replaced by other suitable hinge types. The hinge 8 links the two shells 401, 501 to each other, so as to form a spherical shell, when the ornament is in the closed state. The hinge 8 allows the two shells rotate relative to each other about a fixed axis of rotation, when the ornament is brought from the closed to the open state. As seen on FIG. 8E each shell comprises a part 81, 82 of the hinge 8. Each hinge part 81, 82 having an opening for receiving a pin (not shown).

(56) The first and second parts of the ornament 1 may be individually integrally molded, i.e. made from a single mold. The ornament 1 preferably has a spherical shape. The ornament 1 may also have a cylindrical shape.

(57) In the following the ornament 1 is described in relation to FIGS. 4A-7B. FIGS. 4A-B show the first shell part 401, and FIGS. 5A-C show the second shell part 501 of the ornament. FIGS. 6A-B show an embodiment of the locking element 560 gripping the second friction element 200 when the ornament is in the assembled configuration.

(58) The second shell 501 of the ornament 1 comprises a closing element 502 for releasably securing the first and second parts 400; 500 of the ornament 1 to each other in a closed state of the ornament 1. The closing element 502 is arranged inside the ornament 1, so that the ornament 1 encloses the closing element 502 in the closed state. The closing element 502 is a leaf spring attached to the inside of the shell 501.

(59) An extending part 503 of the leaf spring 502 extends out from the shell 501 and extends in the closed state of the ornament 1 into the first part 400, where it abuts a part of the shell part 401 of the first part 400. The first shell 401 comprises a closing cavity 402 for receiving the extending part 503 of the leaf spring 502 (as seen on FIGS. 7A and 7B). The closing cavity 402 comprises a closing protrusion 403. The closing protrusion 403 provides a releasable snap-lock with the extending part 503 of the spring 502. The second friction element 200 is arranged on top of the closing element 502 and at least partly secures the closing element 502 to the shell 501 of the second part 500.

(60) As illustrated in FIGS. 6A-B, the locking element 560 is in the form of a flange 561, extending along the through hole axis A and being configured to grip the second friction element 200 and secure it to the shell. The locking element 560 further comprises two supporting flanges 562, 563 arranged opposite the flange 561, the supporting flanges 562, 563 being configured to grip the side of the second friction element 200 opposite from the side which is gripped by the flange 561, so as to assist in securing the second friction element 200 to the shell part 501. The flange 561 and the supporting flanges 562, 563 have concave shapes so as to be able to accommodate and grip the first and second wings 201, 202 of the second friction element 200.

(61) As illustrated in FIGS. 4A-B, the shell 401 has an outer surface 4010 and an inner surface 4011. The shell part 401 comprises two side walls 461, 462 extending from the inner surface of the shell part 401. The two side walls 461, 462 are configured to grip the first friction element 100 and assist in securing the first friction element 100 in the cavity 460, so that the first friction element 100 is prevented from being detached from the shell during the sliding movement.

(62) As seen in FIG. 7A, the volume of the part of the first friction element 100, which part is inserted into the cavity 460, is smaller than the volume of the cavity 460, so that when the ornament 1 is in the assembled configuration, the first friction element 100 does not occupy all of the available space of the cavity 460. Hereby, a free expansion space 463 is formed between a bottom of the friction element 100 and a bottom of the cavity 460, at least when the friction element 100 is in an un-compressed state, thereby allowing the friction element 100 to expand further into the cavity 460 (i.e. into the free expansion space) in response to a force exerted by the elongated member 300 on the friction element 100, when the ornament 1 is strung on the elongated member 300.

(63) The first friction element 100 and the second friction element 200 may be manufactured from a material substantially consisting of silicone. The first friction element 100 may be manufactured by separately manufacturing the first friction part 120 and the first retaining part 110 and subsequently attaching them to each other. The second friction element 200 may also be manufactured by separately manufacturing the second friction part 220 and the second retaining part 210 and subsequently attaching them to each other. The subsequent attachment may be done by vulcanization in a contact area of the respective friction element 100, 200.

(64) FIGS. 8A-E show assembly of the ornament 1 of an embodiment of the fourth aspect of the disclosure. Each friction element 100, 200 is assembled with its respective shell part 401, 501 in similar ways. With respect to the first friction element 100, the first wing 101 is first inserted into the cavity 460. Subsequently, a force is applied to the first friction element 100, so that the second wing 102 and thereby the first retaining part 110 of the first friction element 100 are snapped into the cavity 460. The entire first retaining part 110 is thereby arranged in the cavity 460. During this, the second hardness shore A of the first retaining part 110 acts to prevent the first friction element 100 from being detached from the shell during the described sliding movement of the ornament 1.

(65) With respect to the second friction element 200, the first wing 201 is inserted between the flange 561 and the supporting flanges 562, 563. Subsequently, a force is applied to the second friction element 200 (in the direction of the arrows in FIG. 8A), so that the second wing 202 and thereby the second retaining part 210 of the second friction element 200 are snapped between the flange 561 and the supporting flanges 562, 563. During this, the second hardness shore A of the second retaining part 210 acts to prevent the second friction element 200 from being detached from the shell during the described sliding movement of the ornament 1.

(66) In FIG. 8D, the first and second friction elements 100, 200 are shown prior to application of the force. When the force is applied to the respective friction element 100, 200, the element 100, 200 will snap into position in the cavity 460 with regards to the first friction element 100, or in between the flanges 561, 562 with regards to the second friction element 200. In FIG. 8D, the first and second friction elements 100, 200 are shown after the force has been applied and the friction elements are snapped into position.

(67) FIG. 9 shows a graph illustrating an adhesive force test of a friction element similar to either one of the first or second friction elements 100, 200 described above (i.e. of different hardnesses shore A), compared with a prior art friction element having one hardness. The test is used as a performance test illustrating the friction elements of the disclosure performs as desired, the friction elements maintaining the desired friction and do not fall out of the ornament. The x-axis shows the number of cycles completed and the y-axis shows the adhesive force (N). A cycle is an ornament with a friction element being moves from one position on an elongated member to another, different position on the elongated member by a sliding movement.

(68) The points illustrated with .diamond-solid. show the test results for a friction element as described above in relation to the previous figures, where the friction part is of a material of a hardness shore A of 30, and the retaining part is of a material of a hardness shore A of 60. The points illustrated with .square-solid. show the test results for the friction of the above described embodiment, where the friction part is of a material with a hardness shore A of 30 and the retaining part is of a material with a hardness shore A of 80. The points illustrated with .box-tangle-solidup. show the test results for a friction element consisting of a material of only one hardness shore A. Turning to the end point for all three test, the results after 5000 cycles are; .diamond-solid.=0.87 N, .square-solid.=0.82 N and .box-tangle-solidup.=0.33 N. The two friction elements of the above described embodiment performed in terms of the frictional force 263% and 248%, respectively, better than the friction element of only one hardness after 5000 cycles.

(69) Several tests were performed with different material compositions and shapes. These showed that the prior art friction elements fell out after too few slides, yielding an unsatisfactory result. On the other hand, the friction elements of the disclosure did not fall out during the performance tests.

(70) FIG. 10 shows schematically an embodiment of jewelry system of the second aspect of the disclosure in the form of the bracelet 800. The bracelet 800 can be assembled to form an assembled bracelet as shown. The bracelet 800 comprises the elongated member 300, and the ornament 1 as described above.

(71) When the ornament 1 has been strung on the elongated member 300, the ornament 1 can be releasably secured in a first location 310 on the elongated member 300 and be relocated by a sliding movement along the elongated member 300 (indicated by the arrow) to be releasably secured at a second location 320. The bracelet may also comprise a further, identical ornament, also designated 1.

(72) The bracelet 800 may further comprise a freely moveable ornament 2 strung on the elongated member 300. The bracelet could also comprise one or more further similar freely moveable ornament strung on the elongated member 300. The freely moveable ornament is an ordinary bead or charm with no friction element.

(73) The bracelet 800 further comprises two bands 301 fixed to the elongated member 300. The bands 301 have an extended width in a radial direction of the elongated member 300 compared to a similar width of remaining parts of the elongated member 300. The ornaments 1 are configured so that the first and second gripping surfaces may grip the respective bands 301 to allow the ornaments 1 to be releasably attached to the band 301.

(74) The elongated member 300 comprises two ends and a closing mechanism in the form of a conventional jewelry lock 390, e.g. of the hook-and-loop type, the lock 390 being adapted to connect the ends of the elongated member 300, so that the elongated member 300 and the lock 390 form a closed loop as shown.

(75) Although some embodiments have been described and shown in detail, the present disclosure is not restricted to them, but may also be embodied in other ways. It is to be understood that other embodiments may be utilised and structural and functional modifications may be made without departing from the scope of the present disclosure.

(76) In device claims enumerating several means, several of these means can be embodied by one and the same item of hardware. The mere fact that certain measures are recited in mutually different dependent claims or described in different embodiments does not indicate that a combination of these measures cannot be used to advantage.

(77) It should be emphasized that the term “comprises/comprising” when used in this specification is taken to specify the presence of stated features, integers, steps, or components but does not preclude the presence or addition of one or more other features, integers, steps, components, or groups thereof.
