Description

[0001] The invention relates to a jewelry ring according to the preamble of claim 1. This ring comprises a first partial ring and a second partial ring which can be fixed to one another by means of a fit, forming a common ring body, by means of a circumferential receiving groove. At least one intermediate ring is received in the receiving groove.

[0002] From EP 1132017 A2 a multi-part jewelry ring is known in which a first partial ring is connected to a second partial ring by means of a fit in such a way that they form a circumferential U-profile in which three rotatable intermediate rings with roller bearings are received.

[0003] A disadvantage of this type of ring is that the fit can loosen during wear, particularly due to sudden impacts and / or temperature fluctuations, potentially leading to the loss of parts of the ring. Furthermore, in many designs of such multi-part rings, it is undesirable for the parts to move relative to each other. Additionally, these rings typically cannot be disassembled without causing damage, for example, to replace or repair a damaged section or intermediate ring.

[0004] The object of the invention is to avoid the aforementioned disadvantages in a generic jewelry ring and to ensure a permanently stable connection. A further object of the invention is to provide a generic jewelry ring that can be separated again, if necessary, essentially without damage.

[0005] This problem is solved by a jewelry ring with the features of claim 1. In addition to their fit, the two partial rings can be mutually secured to one another via a locking mechanism. This locking mechanism allows the two partial rings to be held together in a connected position by a positive locking or quasi-positive locking action, should the fit not provide sufficient holding force against external pressure. In this way, the individual parts of the assembled jewelry ring are connected to one another with particular security and stability.

[0006] In a particularly advantageous embodiment, the two partial rings can be pre-tensioned against each other by means of the locking arrangement, with at least one intermediate ring inserted between them. This allows the jewelry ring to be fitted with at least one of several intermediate rings particularly easily in order to create a specific overall appearance. At the same time, the inserted intermediate ring can be clamped in a desired rotational position between the two partial rings to maintain a predetermined appearance.

[0007] It is advantageous if the first partial ring has a first locking profile and the second partial ring has a second locking profile, and one of the locking profiles, in a connected position of the locking arrangement, is radially pre-tensioned against a chamfered entry area of ​​an undercut of the other locking profile (which is, for example, designed as a locking receptacle) such that both partial rings are axially pre-tensioned against each other. In this way, the creation of the locking connection between the partial rings can simultaneously be used to generate mutual pre-tensioning against the at least one intermediate ring and thereby clamp it in place. Furthermore, the chamfered entry area of ​​the undercut allows the connected locking arrangement to be released without damage, so that the two partial rings can be separated again if necessary.In this way, it is possible, for example, to replace or rework a damaged partial ring or intermediate ring, or to create a new or different overall appearance by replacing at least one partial ring or intermediate ring.

[0008] Advantageously, the first locking profile and the second locking profile are formed by a circumferential locking recess and a circumferential locking collar, which allows uniformly stable holding forces to be generated over the entire circumference of the ring.

[0009] Furthermore, it is advantageous if the two partial rings can be joined to form a common, radially outwardly open U-profile that limits the receiving groove in order to ensure good visibility of the outer circumferential surface of the at least one intermediate ring or its design.

[0010] Advantageously, at least two intermediate rings are held parallel to each other in the receiving groove, which allows for a particularly versatile design of the jewelry ring.

[0011] Furthermore, it is advantageous if at least two intermediate rings have differently designed outer surfaces. This allows for a particularly complex design, especially when the at least four partial rings have different designs, and offers a large number of different combination possibilities when assembling the ring if the partial and / or intermediate rings are selected from several designs. Both the intermediate rings and the two partial rings can feature different alloy colors, coatings, surface finishes, stone settings, and / or other design options.

[0012] Furthermore, the at least two intermediate rings are held by means of an interference fit on a receiving surface of the receiving groove. In this way, the intermediate rings can also be held in a preferred rotational position by clamping forces acting in a radial direction.

[0013] It should be noted that all the features of the object according to the invention described above are interchangeable or combinable with each other, provided that such an exchange or combination is not excluded for technical reasons.

[0014] The figures illustrate an exemplary embodiment of the invention. They show: Fig. 1 a section through a jewelry ring according to the invention in its assembled state, Fig. 2 an enlarged section through a connecting arrangement of the jewelry ring according to Fig. 1 and Fig. 3. Make a cut through an upper area of ​​the jewelry ring. Fig. 1 in a separate state.

[0015] Fig. Figure 1 shows a multi-part jewelry ring 2 with a first partial ring 4 and a second partial ring 6, which are fixed to one another by means of a connecting arrangement V. In this fixed state, the two partial rings 4, 6 form a circumferential U-profile U, which defines a receiving groove 8 that opens outwards in the radial direction rR. In this receiving groove 8, at least two intermediate rings 10A, 10B are received parallel to each other, as shown, each having an outer circumferential surface 12A, 12B, which are preferably designed differently from one another, in particular with regard to their color, their contour, their stone setting, a possible coating or the like.

[0016] In order to ensure a stable connection between the two partial rings 4, 6 even while wearing the jewelry ring 2 and especially under external forces, the connection arrangement V between the first partial ring 4 and the second partial ring 6 has, in addition to a fit P, such as an interference fit, also a locking arrangement R, by means of which a positive locking or quasi-positive locking action acts between the two partial rings 4, 6 along an axial direction aR.

[0017] In order to additionally fix the intermediate rings 10A, 10B or their outer circumferential surfaces 12A, 12B in a preferred rotational position relative to the partial rings 4, 6 or their shaped outer surfaces 14, 16, they can, at least partially, also be pushed onto the first partial ring 4 with an interference fit acting in the radial direction rR. Furthermore, the two partial rings 4, 6 can also be preloaded against each other in the axial direction aR with the intermediate rings 10A, 10B positioned between them, so that the intermediate rings 10A, 10B are also clamped in the axial direction aR.

[0018] To generate the axially acting positive locking of the locking arrangement R and the clamping holding forces on the intermediate rings 10A, 10B, the first partial ring 4 has a first locking profile 20 and the second partial ring 6 has a second locking profile 22, as can be seen in particular from Fig. As can be seen in Figure 2. The first locking profile 20 forms an exemplary circumferential groove-shaped locking receptacle 24, which acts as an undercut with respect to the axial direction aR and on which a chamfered entry area 26 is formed. The second locking profile 22 forms an engagement element 28 shaped to fit the locking receptacle 24, which, for example, is collar-shaped. When the locking profiles 20, 22 are connected, this engagement element generates restoring forces and presses in the radial direction aR against the chamfered entry area 26 in such a way that the second partial ring 6 is preloaded against the first partial ring 4 with the two intermediate rings 10A, 10B interposed. The groove-shaped locking receptacle 24 and the collar-shaped engagement element 28 can be formed continuously around the circumference or with an interrupted circumferential profile.

[0019] Furthermore, the beveled entry area 26 of the undercut allows the connected locking arrangement R to be released without damage, so that the two partial rings 4, 6 can also be separated from each other again if necessary. In this way, it is possible, for example, to replace or rework a damaged partial ring 4, 6 or intermediate ring 10A, 10B. Alternatively or additionally, a new or different overall appearance of the jewelry ring 2 can be created by replacing at least one partial ring 4, 6 or intermediate ring 10A, 10B.

[0020] The jewelry ring 2 is based on Fig. 3 composed as follows: First, the at least two intermediate rings 10A, 10B are selected according to the design of their outer circumferential surfaces 12A, 12B and, in accordance with the illustrated mounting arrows M1 and M2, are mounted axially aR onto the first partial ring 4, which is separated from the second partial ring 6. They then preferably each have an interference fit with a receiving surface 18 of the first partial ring 4, which forms the subsequent groove bottom of the receiving groove 8, and are thus arranged in a preferred rotational position relative to the first partial ring 4. The outer circumferential surfaces 12A, 12B are selected such that, in combination with the outer surfaces 14, 16 of the partial rings 4, 6, they create a desired overall optical impression.

[0021] The second partial ring 6 is then slid onto the first partial ring 4 in the assembly direction M3, with the two intermediate rings 10A and 10B positioned between them. During this process, the collar-shaped engagement element 28 is elastically pressed outwards in the radial direction aR and pushed onto the receiving surface 18 of the first partial ring 4 until it engages in the detent recess 24 at the chamfered entry area 26. Here, the collar-shaped engagement element 28 is deformed back by elastic restoring forces and thereby pressed inwards in the radial direction rR against the chamfered entry area 26.By applying a radial force rR to the chamfered entry area 26 of the engagement element 28, the second partial ring 6 is pre-tensioned in the axial direction aR against the first partial ring 4, whereby the intermediate rings 10A, 10B arranged between them are fixed in the intended rotational position between the two partial rings 4, 6 by clamping forces acting in the axial direction.

[0022] Should one of the partial rings 4, 6 or one of the at least two intermediate rings 10A, 10B be damaged during the wearing of the jewelry ring, for example by scratches on the outer circumferential surfaces 12A, 12B or on a coating of the intermediate rings 10A, 10B or the partial rings 4, 6, the chamfered entry area 26 of the undercut allows the connected locking arrangement R of the jewelry ring 2 to be released later without damage. This also allows the two partial rings 4, 6 to be separated again if necessary in order to replace or repair a damaged partial ring 4, 6 or intermediate ring 10A, 10B.

[0023] Alternatively or additionally, by replacing at least one partial ring 4, 6 or intermediate ring 10A, 10B, a new or different overall appearance of the jewelry ring 2 can be created if required.

[0024] It should be noted that all the elements and features described above of the various embodiments of the object according to the invention are interchangeable or combinable with each other, provided that such an exchange or combination is not excluded for technical reasons.
