Trinket with swiveling parts

description

The present invention relates to the Oberansprifflflieh claimed and is accordingly concerned with jewelry.

Jewelry of particular value not only requires the use of expensive materials, but should also be processed in an aesthetically pleasing manner. It is desirable to be able to demonstrate a high-quality processing also by the possibility of moving parts of the piece of jewelry against each other. However, this requires that the processing is sufficiently robust and the movement can not cause any damage. Even with filigree pieces of jewelry therefore a sufficiently robust and durable mechanism is necessary.

If multi-piece jewelry pieces are used, it is desirable to be able to use the mobility in order to give the jewelry a different depending on the relative position of the moving parts each different appearance.

It is known to provide jewelry with mutually pivotable elements, such as in a medallion with a lid. It is also known to pop open a lid when a lock is unlocked.

If such a piece of jewelry is unlocked, the interior is however open and the piece of jewelry can in this form in

- l - Normally not be worn without the risk of damage.

From DE 103 15 108 Al a jewelry lock is known on which decorative elements can be securely attached and which is provided with bayonet connections. The known jewelry lock has a base body and a replaceable ornamental element thereon, wherein on opposite base body sides projection recess pairs are provided with projection Zuführrillen- downstream recesses and in these movably crowded projections, so as to allow an ornamental element movement about an axis defined by the pairs.

US Pat. No. 4,052,864 A discloses a piece of jewelry, such as a ring, a brooch or the like, in which a rotational movement about a given point is to take place on the smallest movement of the piece of jewelry. On a pendulum belonging to the jewel, a first magnet is arranged for this purpose, which is intended to be knocked off by an opposing second magnet in order to more easily move the pendulum out of the rest position. This is an unpredictable, stochastic movement.

US Pat. No. 5,873,265 A discloses a piece of jewelery in which an outer piece has an opening in front of which different viewing surfaces of an inner piece can be rotated. The assembly of the inner part is complicated, which are limited by the Innenteildrehung possible variations of the appearance.

From DE 682 938 A a portable as a piece of jewelry in the form of a trailer watch case is known in which the watch case firmly in a back overarching, about hemispherical capsule is also housed with a likewise approximately hemispherical lid, the hemispherical capsule is mounted on the back of the watch case so that see between her and the watch case a free annular space is present, and on its edge a rotatable ring carries, on which within the protective capsule two hemispherical lid forming, approximately quarter spherical and by pivoting in guides on the protective cap pivotable shells are mounted. This capsule is intended to ensure that the lid of the capsule can only be opened and closed intentionally by turning a ring. Such an arrangement virtually completely obscures the movable lids in one position. The use as a chain lock, in which depending on the pivot position different views are shown, is at best difficult and the known arrangement is only intended to be attached to an otherwise closed chain.

It is desirable to provide a way to design a piece of jewelry provided with mutually pivotable parts so that it can be worn problem-free and preferably used as a chain lock and in particular is not given the risk of uncontrolled movement loss or destruction or an unattractive appearance is obtained.

The object of the present invention is to provide new products for commercial use.

The solution to this problem is claimed in an independent form. The present invention therefore proposes, in a first basic idea, a piece of jewelery with a center and at least two parts pivotable relative to one another, it being provided that the pivotable parts, preferably in each case, have a receptacle for attaching jewelery, in particular a receptacle for bayonet plugs, and a multistable pivot position stabilizer is provided to stabilize the parts in more than one, the center partially releasing, user-selectable pivot position relative to each other.

If, as is possible and preferred in one embodiment, a spring means is used which can assume at least two stable, typically minimally compressed layers, it is achieved that the outer parts in these spring means layers are stabilized in their pivoting position. This avoids unwanted back and forth movement of the outer parts; instead, a flare is reached.

By the multistable spring means is made sufficiently rigid, that is, the stiffness of the spring is determined suitable, the stabilization of the outer parts in the pivotal position can be chosen so that an unwanted pivoting is avoided, the outer parts can still be adjusted well.

This is readily given a security in use.

The outer parts will typically have pairs facing each other edge edges, with which they rest against each other in the stable pivotal positions. In this way, an inner part region can be completely covered by the outer parts. the. This is particularly advantageous if the inner part is designed so that a particularly precious, such as adorned jeweled page and a simpler designed page can be shown. As a result, the piece of jewelery can also be readily adapted to different occasions. Preference is therefore further, if the outer parts have in more than one stable pivot position edge edges which bear against each other.

When using only two outer parts, the outer parts will preferably rest against each other in two stable pivot positions. This allows one of two possible areas of an inner part to be released for supervision. The outer part may cover, which is preferred, more than a quarter of the surface of the inner part. Preferably, the inner part corresponds at least in those areas which are exposed in one of the pivot positions, a rotational body and will correspond in the rotational body contour of the outer edge contour of the or the pivotable outer parts. In this way, the marginal edge of the outer part can be guided tightly over the surface of the inner part, thus avoiding the intervening of foreign objects.

The piece of jewelry can preferably be attached to a chain or the like and, in particular, be a chain lock. This is a particularly preferred variant of the invention. This offers the considerable advantage that stable and secure chain locks such as the bayonet locks from the house of the applicant, for example, DE 197 41 406 Al, De-Gbm 76 01 893, DE 199 56 140 Al or DE 103 27 087 Al, are used can . This is made possible in particular by the fact that the outer part has a receptacle for jewelry piece attachment and the inner part opposite the receptacle except, for example, broken or recessed, is. The recess will be typically large enough to allow for achsferner arrangement of the chain closure elements complete pivoting of the outer part; Alternatively, it would be conceivable to make the recording only so large that a desired stop is defined. The described embodiment with a recess penetrating into the inner part region makes it possible to create very robust and secure coupling mechanisms on chains and the like. It should be mentioned, moreover, that alternatively and / or additionally a receptacle for jewelery attachment would also be possible on the axis.

The inner part may have at least one exposed area in all stable pivotal positions, which in each case open areas, as already apparent from the foregoing, preferably be completely disjoint from a stable pivot position to a stable pivot position, whereby otherwise their design may also be completely different.

At the same time, at least one area, preferably at least two diametrically opposite areas, will remain permanently concealed by the outer parts. This ensures that the spring mechanism and the like is not visible or accessible. The spring means can be received as preferred between the outer parts, that is, between the shell and the inner part, for which purpose recesses or recesses or openings can be provided, and Although optionally in the inner part, in at least one of the outer parts or in both.

The outer parts are preferably provided with a connection axis, which also penetrates through the inner part and preferably extends to the diametrically opposite side. This simplifies the mechanical construction with simultaneous mechanical stabilization of the piece of jewelry. Alternatively, a bayonet connector or the like may serve as an axle.

The spring means may be formed from curved spring plates or the like. These can be supported on projections provided on the inner and / or outer part or the like. For this purpose, the curved or curved spring plate may have corresponding projections.

The inner or outer parts may be thinned or removed in the area of the spring sheets. This is preferred because on the one hand, the appearance of the jewelry is not affected and on the other hand, the spring means in the

Recesses are arranged securely and jamming, breakage or the like are not to be feared.

It should be noted that the Schwenklagenstabilisie- means must not be formed only as a spring. Rather, other variants are possible. In particular, it is possible to provide a plurality of cooperating magnets on the jewel of the invention, which stabilize the outer parts in certain pivotal positions. In this case, the stabilization usually and preferably by the attraction of the North Pole on a magnet through the South Pole at another Magnet causes; less preferred is to use a repulsion-induced displacement for stabilization.

A stabilization of the pivoting position by means of magnets can preferably be achieved by arranging the magnets on the mutually facing edges of the outer parts so that the magnets arranged in the edges in mutually adjacent outer parts mutually attract each other, which stabilizes the outer parts in a pivoting position against one another. The magnets can be invisibly incorporated in the outer parts, the material thicknesses typical of jewelery such as chain locks are sufficient to hold magnets of sufficient strength. It should be noted that the magnets are preferably recessed, edged, glued or otherwise held captive without the need for soldering that could potentially damage the magnets.

Another possibility is that at least one magnet arranged on an outer part lies opposite a magnet arranged in the inner part of the jewelery piece at least in one pivotal position, the magnets typically being paired such that a mutual attraction and thus a corresponding stabilization results.

The invention will now be described by way of example only with reference to the drawings. In this is represented by

Shape.

According to Fig. Ia comprises a generally designated 1 piece of jewelry an inner part 2 and two mutually pivotable outer parts 3a, 3b, wherein on inner and / or outer parts a multi-stable spring means 4a, 4b is arranged to the outer parts 3a, 3b in more than a pivotal position about a pivot axis 5 to stabilize.

The jewel 1 is formed in the present case as a lock for a chain and accordingly provided with a clasp, of which only the receiving opening 3al in the outer part 3a and 3bl in the outer part 3b is shown. The clasp may be formed, for example, as a bayonet socket for bayonet head plugs, as known by the applicant.

The jewel 1 is typically formed in its essential, visible to the viewer elements, so the outer parts 3 a, 3 b and the inner part 2 with precious metals such as gold or platinum and may be gem-occupied, as indicated in Fig. Ia by the gem set 2a. The inner part 2a has diametrically opposite two disjoint areas, of which in Fig. Ia only one, see comparison 2bl, is shown. An exemplary design of the diametrically opposite, disjoint other area, which is visible when pivoting the outer parts, can be seen in FIG. 4b as 2b2.

The inner part 2 may be formed solid and then has a through hole, indicated at 2c, through which the connection axis 5 can be pushed. Alternatively, as can be seen in FIG. 2, the inner element may be partially hollow.

The inner part 2 has two projections 2d1, 2d2, which extend generally radially away from the interior and which are dimensioned for supporting a correspondingly bent region of the spring means 4a, compare the bent region 4al or the bent region 4b2 of the spring means 4b. The supports 2dl, 2d2 are generally rounded in the contact region, so that, for example, the curved region 4al of the spring 4a can be pivoted around the projection 2dl, as indicated by arrows 6 and 7, respectively. The inner part 2 is further provided with a recess which is particularly well visible in Fig. 2, cf. recess 2e, provided, in which the receptacle 3al of the outer part can move back and forth in the Außenenteilschwenkbewegung. It will be appreciated that in two outer parts, which are provided with female receptacles, two recesses will be provided in the inner part 2, as indicated at 2el and 2e2.

The outer part 3 has a designed according to the intended appearance of the piece of jewelry outside, in the illustrated embodiment, for example, with gemstone trimming. The external appearance is further marked by the edge of the outer sheath segments, compare 3a2 and 3b2, respectively. The border will typically be designed to be in the stable

Swivel plies edge areas of the different outer parts abut each other. This can be seen in Fig. 4c at reference numeral 7. It should be noted that it is possible to fill the border with gems or to make it in other ways. By opening or closing then different optical impressions can be created only by the different edge design, even if the inner part should be designed identically in the disjoint, in each of the different folding positions visible areas.

As can be seen in particular from FIGS. 3 and 4, the outer part is contoured in such a way that it can slide over the visible or swivel-concealed area of the inner part, but without any risk of contact or snagging. The distance gap between the inner part and the outer part will each be chosen so that a

- II - Unhindered movement without the danger is possible that foreign bodies between the inner and outer part caught or even can get caught.

Bearings 3a3, 3a3 'and 3b3, 3b3' are now provided in the edge, which have a through-opening 3a4, 3a4 "or 3b4, 3b4 'for the penetration of the connecting axis 5. The connecting axle bearings 3a, 3b are arranged on the different outer parts in such a way. That is, for example, as shown in Fig. Ia, the receptacle 3b3 on the enveloping part 3b lies on the outer region of the edge, while the receptacle 3a3 is provided on the inner edge region on the enveloping part 3a Images are, what is preferred, half as wide as the edge, so that at the pivot joints no chunky, but a filigree appearance is obtained without affecting the stability.

In the interior of the outer parts, in addition to the bush receptacles 3al, 3bl also projections 3a5, 3b5 are provided, which extend generally radially inwardly, and as the lugs 2dl, 2d2 of the inner part 2 have a rounded outer contour, in turn, with a bend 4a2 and 4b2 cooperate can, that is, a swinging back and forth of the spring clip 4 a and 4 b to allow around it. The stability of the projections 3a5 and 3b5, in turn, is such that the compressive forces exerted by the springs do not cause any shearing or significant deformation.

The spring means consists here in addition to the supports of two so far identical spring clips 4a, 4b, which are made of sufficiently strong spring steel, such as stainless steel or the like, may be formed and which are adapted to be supported on the respective approaches of the inner and outer parts and to extend therebetween. The dimensioning of the spring parts is such that in the mounted state of the inner and outer parts, the spring clips are respectively bent to such an extent at the arc regions 4a3 and 4b3 extending between the curves with which the spring clips are supported on the projections against the curvature acting restoring forces still overcome when pivoting the outer parts with your fingers, but the forces are sufficient to keep the outer parts stable in the desired positions.

It should be noted that the inner part 2 has a recess in each spring clip, in which this spring clip can move when swinging back and forth. The contour of the inner region is chosen so that the spring clip 4 can be pivoted between 2 positions back and forth without hitting the edges. The corresponding recess can be contoured as indicated in FIG. 2b. The spring clip will not only be curved in a plane between the support ends, but so that it can slide along along the possibly also rotation body-like curved contour of the inner part or the recess of the inner part. For this purpose, the spring clip will usually be curved in two planes.

The contour of the recess for the spring clip, reference numeral 8, is chosen so that the spring clip is more curved in the intermediate layers than in the end positions, in which a stop of the spring means is given at the edge and / or in which the outer edge parts together - Thus, the stop positions are stable positions, while the intermediate positions for the spring clip are unstable.

The piece of jewelry is assembled by first placing the first spring clip in the first outer part, supported on the inwardly facing shoulder. Then, the inner part is inserted, in such a way that the inner part approach engages with the spring at the bend. Thereafter, placed on the opposite side of the spring clip on the inner part and the second Hüllteil is again set to the arrangement, in each case so that the second spring clip is also supported on the approach of the second shell and the rest of the axle bearings of the outer parts are superimposed. The connecting shaft 5, which may be made of precious metal in particular, but does not have to, is then pushed through the axle openings 3b4, 3a4, 2c, 3a4 'and 3b4' and fixed, for example by soldering.

The piece of jewelry can now be worn, it being possible to pivot the two outer parts under temporary compression of the spring clip from a stable position to the second stable position. The spring clip will move around the lugs and assume a stable position. After the pivoting of the outer parts, different, disjoint areas of the inner part are released, which is indicated in FIGS. 3 and 4b, which show one and the same piece of jewelery.

It should be noted that variations are possible, especially with regard to the spring mechanism. Thus, Fig. 5 shows a differently shaped spring clip 9, but also to two Places 9a, 9b at corresponding inner approaches, compare 3a5II are supported on the outer part shown on the right. Moreover, it can be seen that the edge contour of the outer parts does not have to be straight, but can follow a curved, for example, s-shaped line.

Another way to make the spring means multistable, can be seen in Fig. 6. There, an inner part is shown, in which a recess for the socket body has a locking mechanism, wherein the socket body is provided as before on the outer part. In the recess penetrate here spring steel bar, which have an arcuate contour towards the inside. The spring steel yokes 4IIIa to 4IIIc are inserted into slots milled into the inner part and fixed therein. The recess and the spring clip are designed so that the bush is stable in the two extreme edge positions and in the middle position, but is unstable in between, because it is in one of the three stable layers A, B at the spring steel stirrups 4IIIa, 4IIIb, 4IIIc, 4IIId or C will slide. In this way, pieces of jewelry can be realized, which have three stable pivoting positions.

An additional variant is described in FIG. 7. This results in a stabilization of the pivotal positions, by providing on one of the two locking element bushes provided on the outer parts a projection 3aIV, 3bIV of a projection 10, which is formed of spring steel and slides along the edge of the opposing locking element bushing. As a result, it is bent to different degrees during the movement, in such a way that in the respective end positions in which the corresponding edge parts of the outer parts abut one another, a ne particularly low curvature is given, which stabilizes these pivoting positions.

Yet another variant is shown in FIG. 8. In this case, only the relevant elements of the outer parts in different pivot positions A and B and partially transparent from different directions are shown. Reference numeral 10a, 10b shows the outer parts with the socket receptacles IIa, IIb. The outer parts are movable about the pivot axis defined by the joints 12a, 12b.

In the edges of the outer parts 10a, 10b now pairs of magnets are not visible from the outside and thus the appearance of the jewelry not impairing manner incorporated in the outer part 10a of the magnet 13al on one edge and the magnet 13a2 on the other edge, while corresponding magnets 13bl and 13b2 are provided at the edges of the outer part 10b. The magnets 13al and 13bl can be brought into approximation in a pivot position (middle of FIG. 8), the magnets 13a2 and 13b2 in a second pivot position. The orientation of the magnets is such that the magnet pairs 13al and 13bl attract and also 13a2 and 13b2. This is shown under "I" by the indication of the polarities.

Thus, the magnets serve as Schwenklagenstabilmit- tel, which is incorporated obscured for the viewer.

In Fig. 9 is a variant of a piece of jewelry, in turn, a chain lock, shown, in which no inner part, but only two against each other around a center by folding movement movable parts are provided. In front- seen for the piece of jewelry 100 two shell-like parts 300a, 300b, which have bayonet sockets 500a, 500b. In these bayonet plugs, as they are known per se from the locks of the Applicant can be used. The bayonet bushings face radially outward away from the center of the half-shells, but are not disposed on a common axis but at an angle to one another in the stable positions where the edges of the parts abut each other; It should be noted that the parts are shown in a movement phase, so not in a stable end position. The parts 300a, 300b are in contact with each other at bearings corresponding to 3a3, 3a3 "or 3b3, 3b3 'of the variants described above, wherein here the bearing facing the viewer is partially covered by the multi-stable pivoting means 400, which in turn

Pin 600a, 600b is supported. In a fully assembled form, this multi-stable stabilizer will be covered by a cap or the like.

It should be mentioned, moreover, that the pivot-stabilizing spring (s) can also be mounted inside and can also be covered there.

Fig. 10a shows the variant of the piece of jewelry of Fig. 9, namely once as an assembled piece of jewelry (above) and once as an exploded view (below). In this case, different band springs are shown for the exploded view, with which the pivot position stabilizer can be realized.

Fig. 10b shows the same view as Fig. 10a, but with dashed lines.
