Abstract

Jewellery or bijouterie links (1, 2, 3) and jewellery or bijouterie product comprising one or more links and use of the links. The links comprise one or more ring members (5', 5") having a catch (4) formed integrally in the ring member(s) (5', 5"). The catch is formed by at least one end of the ring member (5) being cut off obliquely thereby forming at least one first surface (6', 7'), which are angled at an angle [mu] in relation to each other and wherein the angle [beta] of the oblique surface in relation to the plane of the ring (5' 5', 5") is smaller than the angle [mu]. Preferably, the link further comprises a second surface (6", 7") wherein the first and second end surfaces of each ring end are angled in an angle [beta] in relation to each other, wherein the angle [beta] is smaller than the angle [mu]. Hereby, the links can be assembled into a chain, necklace or bracelet, since each link is provided with a catch (4), thereby rendering a conventional lock superfluous. In addition, the links can be assembled and disassembled at any two adjacent links when applied to e.g. a wrist or a neck as a bracelet or a necklace.

Description

Jewelry/jewelry chain and jewellery/jewelry made from this chain

The present invention relates to jewelry or jewelry links.

The invention also relates to jewelry or jewelry products comprising one or more links, such as chains, bracelets or necklaces.

Furthermore, the invention relates to the use of such links on jewellery or jewellery products, such as chains, bracelets or necklaces.

In the past few centuries, a trend in the jewelry market has been to provide a jewel that allows a jeweler to personalize or customize according to her or his preferences.

Typically, such customized jewellery or jewellery comprises a bracelet or a chain and a pendant comprising a loop or hook is attached thereto. The loop or hook can be attached to the bracelet or necklace. The wearer can then add several different trinkets depending on his or her preference to give the jewelry or jewelry chain a personalized look.

Another example of such customized jewelry or jewellery includes chains with different beads that are simply affixed to the bracelet or pendant on. An example of such a jewellery series is a jewellery sold under the name Trollbeads®.

The necklace or bracelet of the jewelry chain mentioned above is typically a chain with hooks or a necklace or bracelet made of one or more small beads, leather, rubber, textile loops. . Alternatively, the charm or beads are applied to a bangle.

Each of these jewelry chains can provide many possible variations depending on the choice of the wearer of the necklace and/or bracelet or on the charm or bead that is applied to the bracelet or the necklace. However, they all rely on the wearer to select a chain or a bracelet to begin collecting different trinkets or beads for application to the necklace or bracelet.

Therefore, there is a need for another jewellery or jewellery that can be altered by the wearer to produce a personalized appearance of the jewellery or jewellery according to the wearer's preference, and the jewellery or jewellery The choice of necklace or bracelet is not relied upon to create a personalized look of the jewelry or jewelry.

Another example would be to provide a jewel with a link (such as the link disclosed in the US 2010/281918 (A1) patent). The links are connected to each other and their rotational relative positions are restricted by a pin. The links can be attached to each other by providing at least one of the links with a movable locking device and thereby providing a chain, bracelet or necklace. These links have several drawbacks. The first drawback is that the jewel has no way to conform to the wearer's wishes in other ways than by adjusting the length of the chain, bracelet or necklace. The second drawback is that these links have a mechanical A locking mechanism that contains moving parts and is easily broken.

The present invention eliminates the disadvantages of the above-mentioned conventional jewelry or jewelry products and provides a chain of links formed by different links having different designs, which can be combined into a jewel or Jewelry products, such as a chain, necklace or bracelet.

The links include a integrally formed hook portion that enables the links to be assembled into a chain, necklace or bracelet and allows the user to create the jewelry or jewelry based on the selected link Appearance.

The integrally formed hooks in each link can be assembled by simply attaching one link to the other or attaching to a chain of links. A chain, bracelet or necklace is used without the need to use a separate bracelet, necklace or chain to attach the links to it.

Thus, the links provide the possibility of producing different jewels or jewellery that can be altered by the wearer to produce a personalized appearance of the jewellery or jewellery according to the wearer's preference, and Jewelry or jewelry does not rely on the choice of necklace or bracelet to create a personalized look of the jewelry or jewelry.

In addition, in the case where the user wishes to remove one link and add another link to the chain, the necklace or the bracelet, this is permeable. The integrally formed hook portion is easily achieved by removing the target link and adding a new link.

Thus, the necklace or bracelet can be opened at any point in the chain of the chain by separating two adjacent links for fitting the necklace or bracelet to the user's neck. Or on the wrist or from the user's neck or wrist. This also saves the trouble of separating the lock on the hand ring or the necklace.

These objects may be achieved by a jewelry or jewelry link having a hook portion, the link comprising a ring member having two opposite end faces forming the hook portion, wherein at least one of the first end faces has a slanted a cutout portion for forming an angle μ with the opposite end surface, and an angle β of the slope relative to a plane of the ring member is equal to or smaller than an angle μ between the end faces.

In a preferred embodiment, the two end faces of the ring are obliquely cut away, which allows the links to be more easily and correctly relative to each other when assembling the links into a chain, necklace or bracelet. Place.

Such objects may also be achieved by a preferred embodiment of the links, in which one end or both ends of the ring member comprise a second obliquely cut end face, It forms an angle β with respect to the first obliquely cut end face and the second faces face away from the first face.

A chain loop is thereby obtained, which is easier to manufacture in a casting process and which provides symmetry in a hooking area. Moreover, the links can be more easily placed relative to one another when assembling the links into a chain, necklace or bracelet. In addition, these links can be wounded without injury. Being assembled in the event of a risk of hooking the hooked areas of the links, because when the links are assembled into a chain, necklace or bracelet, the first and second in the hooking area of a link The face slips simply against the first and second faces in the hooking region of the other link.

The preferred shape of the hooking region of the link is such that the angle β is preferably up to 90°, such as 30°-90° or such as 70°-90°, preferably 80°-90° or optimal. It is achieved at 90° or about 90°.

Similarly, an optimum shape of the hooking region of the link is such that the angle μ is as high as 135°, such as 90°-110° or preferably 90°-100° or optimally 90° or about 90°. Time is reached.

When the first or second bevel forms a 10°-80° or preferably 25°-65°, or more preferably 30°-60° or optimally 45° or about 45 with respect to the plane of the ring member At an angle a of °, it is easier to place the hooking regions of the two links relative to one another when assembling the links into a chain, necklace or bracelet.

In another embodiment, the first and second faces are substantially flat, whereby the first and second faces are more easily offset when the links are assembled into a chain, necklace or bracelet. Sliding on each other.

In still another embodiment, the jewelry or jewelry link includes a first ring member extending in a first plane (XY) and an attachment to the first ring member and extending in a second plane (XZ) a second ring member, wherein the first and second planes form an angle with respect to each other. Other variations of the jewelry or jewellery product can be provided by providing a double chain loop, for example by being able to combine a single loop chain and a double loop chain to provide variation.

The angle between the first and second ring members can be varied to achieve a different jewellery or jewelry link appearance. At an angle of 90° or substantially 90°, the chain of links formed by the links does not twist. When the angle is less than 90°, a twisted appearance can be obtained on the chain of links formed by the links, and the degree of twist is related to the angle between the first and second rings. The appropriate angle for obtaining the desired twisted appearance on the chain, necklace or bracelet is preferably between 60 and 90, such as from 70 to 90 or preferably from 80 to 90°, especially from 85° to 90°.

In still another embodiment of the jewelry or jewelry link, the second ring member includes another lock member integrally formed within the link, such as a carabiner lock, which includes a Latch-operated latch. The other lock member is simply hooked into the ring member of a chain of the chain for locking the bracelet chain or necklace. In the case where the user frequently wears and removes the bracelet or the necklace, the present invention allows the cause to be assembled and disassembled into a chain, necklace or bracelet using the integrally formed hook member. The wear caused by the hooks on each link for daily use is significantly reduced.

Preferably, the ring members of the link according to the present invention are oval, substantially oval, circular, or substantially circular, or polygonal, such as square, rectangular, pentagonal, hexagonal, heptagonal. Or octagonal, etc., and more preferably in the form of an oval or a solid ovate, as the chain, necklace or bracelet it forms can be worn more comfortably on the user's wrist or neck or worn on the jewel or Jewelry on any part of the body. An oval ring or similar elongated ring will also cause the chain on the chain, necklace or bracelet to be natural The ground will occupy the longitudinal position of the chain, ie their longitudinal axis X-X is along the length of the chain, necklace or bracelet. Therefore, preferably, the hook portion is formed at a position of the ring member, the position being a position corresponding to the shortest diameter of the ring member and the oval ring member for reducing two adjacent periods during use. The possibility that the links are accidentally separated from each other.

Moreover, the present invention solves the above problems and provides the above advantages by providing a jewelry or jewelry product comprising one or more links according to the present invention. The jewellery or jewellery product forms a chain, bracelet or necklace.

Furthermore, the present invention solves the above problems and provides the above advantages by using one or more jewelry or jewelry links according to the present invention on jewelry or jewelry products, such as chains, bracelets or necklaces.

The links shown in 1e are assembled into a chain, bracelet or necklace or the like. Figure 2f shows a schematic cross-sectional view through the hooking area during assembly of the two links shown in Figure 2e, Figure 2g shows FIG. 2h is a perspective view showing the chain ring shown in FIG. 1f assembled into a chain, a bracelet or a necklace or the like, during assembly of the two links shown in FIGS. 2a-2d. Figure 3a shows a side view of a chain, bracelet or necklace comprising a single chain according to the invention, and Figure 3b shows a side view of a chain, bracelet or necklace comprising a double chain ring according to the invention, wherein the double chain The ring includes a link including another hook, and Figure 3c A side view of the chain, bracelet or necklace of Figure 3b is shown showing that the chain, bracelet or necklace uses the engagement that includes the other hook.

Figures 1a-1f show a jewelry or jewelry link in accordance with the present invention Several possible embodiments of (hereinafter referred to simply as links).

Figures 1a, 1e and 1f show the simplest form of a link 1 according to the invention. The link comprises a ring member 5 that extends substantially in a plane defined by the X and Y axes.

Ring member 5 refers to a ring member having a cut extending through a ring material formed into a rod, cylinder or the like and bent into a ring shape or a similarly shaped chain by casting. ring. The rod/cylinder or the like forming the ring member 5 has a diameter d, see Figs. 1a and 1c.

The link 1 has a hooking portion 4 which is integrally formed on the ring member 5. The hook portion 4 is formed at a slit passing through the ring member 5, which will be described in detail below with reference to Figs. 1e, 1f and 1b.

Another embodiment of a link according to the invention is shown in Figure 1b. The link 2 in Fig. 1b has two ring members 5', 5" attached to each other and is thus referred to as a double chain ring 2. The double chain ring 2 comprises a first one extending over a first plane XY The ring member 5', i.e., the XY plane, passes through the centerline at a distance d/2 of the cross section of the first ring member 5', as shown in Figures 1b and 1c, and a second ring member 5" is firmly attached thereto. The first ring member 5' extends over a second plane XZ. The first plane X-Y and the second plane X-Z form an angle a with respect to each other, see Fig. 1c. The angle a (Fig. 1c) is preferably about 90°, and the two ring members 5' and 5" are thus orthogonal or substantially orthogonal to each other and the links are assembled into a chain, necklace or bracelet. They are substantially orthogonal to each other, as shown in Figures 3b and 3c. In the case where a twisted chain, necklace or bracelet is desired, the angle can vary from 70° to 110°. Preferably, it is between 80° and 100°, especially between 85° and 95° or optimally 90° or about 90°. For example, a twisted chain can be obtained, wherein the angle between the first ring member 5' and the second ring member 5" is about 75[deg.] (ie, the YY axis and the ZZ axis are deflected by an angle of 75[deg.] When the six links provide a 90° twist, at 90° or about 90°, the chain, necklace or bracelet assembled with the link will not twist.

The double-chained ring 2 can be formed, for example, by forming two separate ring members 5' and 5" welded together, or by directly forming a double-chained ring 2 by casting.

The hooking portion 4 will be explained with reference to Fig. 1b, but it should be noted that the hooking portion 4 is formed as follows, but does not necessarily have to be identical to all of the links 1, 2, and 3 according to the present invention. The single link 1 (Fig. 1a, 1e), the double link 2 (Fig. 1b), and the lock link 3 (Fig. 1d) can be combined in any desired manner.

The hooking portion 4 on a ring member 5, 5', 5" is formed, for example, by providing a cut-out at an angle at at least one end portion 6, 7 of the ring member 5, 5', 5" for One or more angled faces 6'-6", 7'-7" are formed at one end or both ends of the ring member 5, 5', 5" (see Figures 1a, 1b, 1e and 1f) In the simplest form of the hooking region 4 (see Fig. 1e), one end of the ring member 5 has a chamfered surface 6 which forms an angle μ with the opposite end face 7 (see Fig. 1e, 1d, 2e-2g) and the plane XY of the bevel 6 with respect to the ring member 5, 5', 5"; the angle β of XZ is equal to or smaller than the angle μ between the end faces 6, 7. Then, the bevels 6 of the two links are assembled into a chain, necklace or The bracelets slide towards each other as shown in Figure 2e. Preferably, the two end portions 6, 7 of the ring member 5 comprise a chamfered surface 6, 7 as shown in Figures 1f and 2h, which causes the links 1, 2, 3 to assemble the links 1, 2, 3 into one Chains, necklaces or bracelets are easier to place correctly relative to each other.

Preferably, each end of the ring members 5, 5', 5" has at least two angled faces 6'-6", 7'-7", as shown in Figures 1a, 1b, 1d and 2a-2d The angled faces thus form a wedge-shaped end on the ring 5, 5', 5" having an edge 8 directed at the edge of the other end of the ring 5, 5', 5" 8. The edges 8 at the ends are preferably parallel to and substantially the same distance from the central plane XY or XZ of the ring, and thus form a narrow gap between the opposite edges 8, which The gap can provide the necessary tolerance for the hooking portion 4 to ensure easy attachment or separation of the links 1, 2, 3 as described below.

This causes the hooks 4 of each link 1, 2, 3 to be easily attached to any other link 1, 2, 3 to form a chain, necklace or bracelet (this will be further hereinafter) Note) because the links can be easily placed relative to each other. Alternatively, any two adjacent links can be easily uncoupled from each other to fit the wrist or neck to or from the wrist or neck, or to add additional links Replace any chain with the chain, necklace or bracelet, or with new links 1, 2, 3. This also causes the links 1, 2 to be used in any desired combination of the single link 1 and/or the double link 2 and/or the lock link 3.

Each end of the ring member 5, 5', 5" has at least a first face 6', 7' which is in an X-Y plane relative to the ring member 5, 5', 5", respectively. Or the angle α of the X-Z plane extends in the A-Y plane or the B-Y plane, respectively. Thereby, the AY plane or the BY plane of the first opposing faces 6', 7' on each end of the ring members 5, 5', 5" form an angle μ with respect to each other. These first faces 6 ', 7' are preferably substantially orthogonal to each other, i.e. the angle μ is preferably 90° or about 90°, but other angles between the first faces 6', 7' are also feasible. An angle of up to 135°, such as an angle of 90°-110° or 90°-100°.

The value of the angle μ can also be related to the value of the angle β described below, since each end of the ring member 5, 5', 5" respectively includes two chamfered faces 6', 7' and At 6", 7", the sum of the angle μ and the angle β is 180°, see Figures 1a-1d, 2a-2d and 2f.

Preferably, the hook portion 4 on the ring member 5, 5', 5" further comprises a second face 6", 7" from each end of the ring member 5, 5', 5" respectively The edge 8 of the portion extends over the AY or BY plane such that each second face 6", 7" faces away from their respective first faces 6', 7' and the first and second faces of the AY; BY The planes form an angle β with respect to each other which can be up to 90°, such as 30°-90° or such as 70°-90°, preferably 80°-90° or optimally 90° or about 90°.

The angle α of the plane of the AY or BY plane relative to the plane of the ring member 5, 5', 5" (ie, XY or XZ) may be between 10° and 80°, or preferably between 25°. Between -65°, or more preferably between 30° and 60° or optimally 45° or about 45°.

In a particularly preferred embodiment, the angle β and the angle μ are 90° or about 90° and the angle α is 45° or about 45°, whereby the links are the most It is easy to assemble into a chain, necklace or bracelet because the two links can be easily placed in a substantially orthogonal manner to each other prior to assembly. Furthermore, the user does not have to consider how to correctly place the chamfers 6, 7 to assemble any two links 1, 2, 3 into a chain, necklace or bracelet with respect to each other.

The first and second faces 6'+6", 7'+7" are preferably flat or substantially flat, respectively, whereby the faces can be assembled into a chain, necklace or bracelet at the chains. It can easily slide against each other as shown in Figures 3a-3c.

In another embodiment of the link 3 (see Fig. 1d), the other lock 9 is integrally formed in a double chain ring similar to the link 2 shown in Fig. 1b. Preferably, the other lock 9 resembles a conventional lock that includes a latch (10) that is biased by a spring (not shown) and operated by a lever (11). The first ring member 5' as described above is provided with the key fob lock 9, wherein the hook 5'" of the key fob lock 9 and the latch 10 are preferably designed as shown in Fig. 1b. The second ring member 5" of the illustrated double link ring is similar. This "locking link" 3 can be used to provide a conventional lock 9 at one end of a chain of links 2, 2 forming a bracelet or necklace, as shown in Figures 3b and 3c. The key fob lock 9 is simply hooked into any of the ring members 5, 5', 5" of a link of the chain for locking the bracelet or necklace. It is frequently worn and taken by the user. In the case of a lower hand ring or a necklace, the present invention allows each of the links to be connected to a chain, a necklace or a bracelet as a lock member using the integrally formed hook member 4 as a lock member. The wear caused by the hooks 4 on one of the links 1, 2 is significantly reduced.

The hook portion 4 on all links 1, 2, 3 is preferably The same, as a result, the single link 1, the double link 2, and the lock link 3 can be combined in any desired manner. Furthermore, the first ring member and/or the second ring member (5, 5', 5") are preferably oval, substantially oval, circular, or substantially circular, or polygonal, such as square, rectangular, A pentagon, a hexagon, a heptagon, or an octagon.

Preferably, the first ring member and/or the second ring member (5, 5', 5") are in the form of an oval or a substantially oval shape because the chain, necklace or bracelet formed thereby can be more comfortable Worn on the user's wrist or neck or on any part of the body wearing the jewelry or jewelry. An oval ring or similar elongated ring will also cause the link 1 on the chain, necklace or bracelet. , 2, 3 naturally occupy the longitudinal position of the chain, that is, their longitudinal axis XX is along the length of the chain, necklace or bracelet, see Figures 3a-3c. Therefore, preferably, the hook The joint 4 is formed on the ring members at a portion of the ring members 5, 5', 5", the portion being the ring member 5, 5', 5" and the shortest diameter of the oval ring member (ie, the portion corresponding to or adjacent to the YY axis or the ZZ axis) to reduce the likelihood that two adjacent links 1, 2 will accidentally separate from one another during use.

The assembly of a chain using the links 1, 2, 3 of the integrally formed hook portion 4 has been described with reference to Figures 2a-2e and 2h. The two links A and B are kept substantially orthogonal to each other by having their respective hooks 4 facing the other links A, B, see Figure 2a. Then, the hook portions 4 of the links A, B will engage when the links A, B are pressed toward each other as indicated by arrows C, D in Fig. 2b. Since the cut-away portion of the hook portion 4 of the first link A corresponds to the wedge shape of the end portion of the ring member formed at the other link B, Therefore, the faces 6', 6" and 7', 7" of the link A (see the symbol of Fig. 1b) will slide against the faces 6', 6" and 7', 7" of the link A (Fig. 2c) Shown) until the links are completely hooked together, as shown in Figure 2c. In Figure 2c, the ring member 5' of the link A grasps the ring member 5" of the link B. Figure 2d shows the final position of the links A and B in a chain of links forming a chain, necklace or bracelet. .

As seen in Figures 3c and 2d as seen in 3a-3c, each link is free to move relative to adjacent links in the chain.

The jewelry links 1, 2, 3 are preferably made in a casting manner from precious metals such as gold, silver, platinum or alloys thereof, such as bronze. Alternatively, titanium or steel alloys conventionally used for jewelry or jewelry may be used, or other metals or metal alloys conventionally used in jewelry may also be used. In addition, synthetic materials (such as plastic or rubber) conventionally used for jewelry can be used. Suitable plastics are relatively rigid and rigid, such as polyethylene terephthalate (PET), polyester, polyamide or nylon, and polyvinyl chloride (PVC).

As mentioned above, the links 1, 2, 3 can be used on jewelry or jewelry comprising one or more of the links described above, such as a chain, a bracelet or a chain.

In the drawings, the links are shown in their simplest form. Of course, it is possible to produce a series of differently designed links as a variation of these basic forms. For example, each end of the ring member 5, 5', 5" may be provided with an additional two bevels (not shown) extending at the edge 8 of each end of the ring members 5, 5', 5" On a substantially orthogonal plane. in In this example, the faces may thus form angles which are used as the hooking portion 4 on the first face and/or the second face 6', 6", 7' + 7" in the additional faces. The angle in the example of the surface other than the plane defined by the first surface and the second surface 6'+6", 7'+7" corresponds to. Alternatively, the ends of the ring members 5, 5', 5" may be provided with two or more additional bevels and the angles of these additional faces may be arbitrarily selected for use in the ring members 5, 5' The end of the 5" gets a desired look.

The links 1, 2, 3 may of course also be used by those skilled in the art of jewelry design and manufacture by using different metals in various variations of the links, by combining different metals in each link. They are modified by their surface treatment and/or by inlaying pearls, gems, stones, etc. to decorate the links. Thereby, the wearer can select a different link and thereby create a personalized design for his or her chain, bracelet or necklace.

Substantial, primary, approximate, approximate, etc., such as substantially oval, should be understood to encompass both the art of hand-crafting or casting jewels and the visual inspection of shapes, forms, angles, etc. and related forms, Angles and the like are within the normal tolerances accepted by those skilled in the art.
