Description

ring

[0001] The present invention relates to a ring, in particular a jewelry ring or smart ring, comprising at least one ring band and at least one receiving element for receiving at least one jewelry element and / or at least one electronic component. State of the art

[0002] The age-old problem of rings, especially hallmarked ones, causing pain when slipping onto the finger joint has plagued jewelers and goldsmiths for centuries. On the one hand, the ring must be wide enough to pass over the joint with minimal pain; on the other hand, it must be tight enough to ensure a secure fit in its final position and prevent it from twisting downwards due to any stone setting. However, since the finger joint is often the widest part of the finger (a width that constantly fluctuates depending on the time of day, temperature, and age), rings with stones or other gemstones—especially those with larger, heavier settings—frequently don't fit snugly enough and can easily twist downwards.If the ring were designed so tightly that such twisting was not possible, the ring could no longer be pushed over the finger joint (at least not without causing pain or injury).

[0003] In the prior art, this problem is often solved by using specific materials; however, due to the presence of base metals, this usually results in such rings no longer being hallmarkable. For example, with known pearl rings where drilled pearls are held on a flexible (rubber) band, the problem arises—apart from the lack of hallmarkability—that such "rings" or bands are not comparable to solid (jewelry) rings in terms of their dimensional stability, durability, and value.

[0004] Furthermore, rings whose ring shank is interrupted at one point to allow bending or stretching of the ring shank are generally known. Such rings can, on the one hand, comprise circularly arranged ring shanks that are interrupted or not closed at one point, or be formed by such Ring rails can be formed. Alternatively, overlapping ring rails or those arranged in the manner of a helical spring can be used to allow for ring size variability. Even with such rings, the ring rail is not closed, but extends helically from one end to the other.

[0005] A disadvantage of such rings is that the bands, particularly at breaks or exposed free ends, tend to snag on other objects, posing a significant risk of injury. Furthermore, the unrestricted and continuous bending or stretching of these rings leads to material fatigue, making them prone to breakage. Finally, due to their unusual appearance, which differs from classic rings with stone settings, these rings often have a costume jewelry character, meaning they are not a viable alternative for many users facing the aforementioned problem. Description of the invention

[0006] The present invention therefore aims to provide a ring that can be worn, for example, as jewelry and / or as a smart ring, while avoiding the disadvantages described above. Further objectives of the invention will become apparent from the description and the figures.

[0007] One object of the invention is solved by a ring, in particular a jewelry ring or smart ring, comprising at least one ring band and at least one receiving element for receiving at least one jewelry element and / or at least one electronic component, wherein a first end of the ring band is rigidly connected to the receiving element and a second end of the ring band is movably mounted in or on the receiving element to enable a ring size change.

[0008] According to the invention, the ring initially comprises the ring rail, to which the receiving element is attached. Unlike known rings, however, the ring rail is not rigidly connected to the receiving element at both ends, nor is the receiving element mounted on a closed ring rail. Instead, one end of the ring rail, i.e., the first end, is rigidly connected to the receiving element, in particular by soldering, preferably by laser soldering; another end of the ring rail, i.e., the second end, is not rigidly connected to the receiving element. The ring shank is not connected to the receiving element, but rather movably mounted in or on it. This makes it possible to vary the effective circumference of the ring shank available outside the receiving element, namely by moving the second end of the ring shank towards or away from the first end. This movable mounting of the second end creates a spring effect in the ring shank, thus enabling a change in ring size. The ring shank can be designed, or the spring effect, spring force, or spring constant of the ring shank can be dimensioned such that easy, simple, and painless application and removal of the ring is possible, and a secure fit of the ring is ensured.In particular, the ring according to the invention, which has a specific ring size in a rest position of the ring band described in more detail below, can be slid onto a user's finger. During this process, the ring can expand in the area of ​​the finger joint due to the counter-pressure exerted by the finger joint on the ring band, thereby increasing the ring size accordingly (first ring size change). After passing the finger joint, the ring band can return to its rest position, or at least to a relaxed position compared to the position expanded in the area of ​​the finger joint, thereby reducing the ring size again or even returning it to the original ring size that the ring has when the ring band is in its rest position (second ring size change).This allows for painless and easy putting on and taking off of the ring, as the finger joint can be easily passed thanks to the (first) ring size adjustment. Furthermore, it ensures that the ring has a secure hold in its predetermined final position behind the finger joint, where rings are typically worn, and that the ring does not twist downwards due to any stone setting. This is especially important because the (second) ring size adjustment after passing the finger joint allows for a ring size that is specifically adapted to the predetermined final position on the finger – and not, as with conventional rings, also to the area of ​​the finger joint. The ring band can be spring-mounted or clamped to the setting.

[0009] The resulting ring size change can preferably comprise or effect 1, 2, 3, or 4 ring sizes. For example, the ring in the rest position of the ring band can have a ring size of 54 (inner circumference of the ring band in mm) and, by applying the force causing a ring size change (acting from the inside out), such as when passing over the finger joint, continuously to a ring size of 55 (with a maximum ring size change of The ring band can be extended by one ring size), 56 (with a maximum ring size change of two ring sizes), 57 (with a maximum ring size change of three ring sizes), or 58 (with a maximum ring size change of four ring sizes). This extension, and the subsequent return of the ring band to its rest position when the force causing the ring size change is removed, resulting in a reduction of the ring size to the original size 54, is due, on the one hand, to the movable or spring-like mounting of the second end of the ring band in or on the receiving element (described above), and, on the other hand, to the (elastic) deformability of the ring band. With such a ring size variability (for example, by one to four ring sizes), almost all finger sizes and joint structures are covered.

[0010] In a preferred embodiment of the ring, the receiving element has a through-opening through which the ring rail projects into the receiving element.

[0011] An end section of the ring shank, which is guided (preferably with some play) through the opening and extends within the receiving element, encompasses the second end. Thus, the second end of the ring shank is supported within the receiving element, at least when the ring shank is in its resting position, in which position it is not subjected to any force that would cause a change in ring size. This reliably prevents the ring shank from snagging on or becoming entangled in other objects, as the free second end of the ring shank is not exposed but rather housed within the receiving element. This ensures safe wearing and improved handling of the ring.

[0012] In a preferred embodiment of the ring, the second end of the ring rail has a cross-sectional expansion or is formed by a cross-sectional expansion.

[0013] To prevent the second end from being pulled out of the receiving element through the opening, for example, when the ring is slid over the finger joint during application or removal, a cross-sectional expansion is provided. In the area of ​​this expansion, the ring band has a larger diameter or cross-section than in the end section of the ring band and / or in other sections of the ring band. The cross-sectional expansion can be designed such that complete removal of the end section and / or the second end from the receiving element is prevented. The removal of the ring rail from the receiving element is made more difficult or even impossible. This can be achieved, for example, by ensuring that the ring rail has a diameter in the area of ​​cross-sectional expansion that corresponds to or is identical with the (clear inner) diameter of the through-hole. In this way, further withdrawal of the ring rail or its end section from the receiving element can be made more difficult or even impossible by means of a positive and / or non-positive contact between the ring rail and the through-hole (or a wall of the through-hole that borders the through-hole).

[0014] In a preferred embodiment of the ring, it is provided that the diameter of the cross-sectional expansion is larger than the diameter of the through-opening.

[0015] The cross-sectional expansion creates a stop that limits the movement of the ring band. This reliably prevents the second end from being pulled out of the receiving element. Furthermore, this design allows for the definition of a maximum ring size that the ring can assume when a force causing a change in ring size acts on the band – for example, when passing through the finger joint. However, this also defines the maximum elastic deformation or deformability of the ring band, which is not the case with known rings that have a discontinuous band. In such rings, the band can be deformed arbitrarily if the applied force is sufficient, which, if overstressed (i.e., if the deformation is too great), can lead to the ring band breaking and / or being plastically deformed by overstretching.This can be reliably prevented in the ring according to the invention by means of the stop. As soon as the ring rail has been pulled out of the receiving element to such an extent that the end section and / or the second end of the ring rail with the cross-sectional extension rests against or contacts an inner surface of the receiving element, i.e., an area of ​​the inner surface surrounding the through-opening, a positive fit is established between the ring rail and the receiving element. This positive fit prevents further pulling of the ring rail out of the receiving element. This avoids damage to or overstretching of the ring and increases its service life.

[0016] Preferably, the stop is formed by an eyelet (also formed from round wire), which is connected, in particular soldered, to the ring rail or the second end of the ring rail. Soft solders (i.e., solders with softening temperatures below 450 °C) are particularly preferred, which has the advantage that the elastic deformability of the ring rail is largely preserved. The eyelet can be connected to the ring rail by laser soldering, which also has the advantage of preserving the ring rail's elastic deformability to a particularly high degree. This allows the spring action of the ring rail, which is movably mounted in (or on) the receiving element, to be utilized very effectively, enabling particularly easy, comfortable, and secure attachment and removal of the ring. Annealing, especially red or dark red annealing, of the ring rail can thus be (largely or completely) avoided, allowing the ring rail to retain its dimensional stability (i.e., stiffness, strength, or hardness). This also applies analogously to the connection or soldering of the first end of the ring rail to the receiving element.

[0017] In a preferred embodiment of the ring, at least three hollow spheres rotatably mounted on the ring rail are provided, with each of the three hollow spheres being arranged in its own third of the circle of the ring rail.

[0018] The arrangement of at least three hollow spheres in different thirds of the ring's circular band creates a three-point contact with the user's finger. This allows the ring to be guided along the finger at these three points, or rather, with these three hollow spheres, when putting it on and taking it off. The rotating mounting of the at least three hollow spheres on the ring band creates a rolling effect, making it particularly easy to put the ring on and take it off. Because this rolling effect makes it easier to overcome the finger joint, it also becomes possible to use even smaller ring sizes than with conventional rings, which further contributes to a particularly secure fit. In particular, the hollow spheres of the ring create spherical indentations in the user's skin, increasing the ring's contact area and, due to the increased friction, ensuring even better adhesion to the finger.This reliably prevents the ring from twisting, even in rings with very large and heavy stone settings.

[0019] In a preferred embodiment of the ring, it is provided that further hollow spheres are mounted on the ring rail in such a way that the hollow spheres are arranged next to each other and rotatably on the ring rail in a rest position of the ring rail, in which rest position the ring rail is not subjected to a force causing a change in ring size.

[0020] This makes the rolling effect described above even more pronounced, simplifying the handling of the ring and further improving wearing comfort. In particular, the ring can be adjusted when putting it on and taking it off. All hollow spheres are supported by or guided along the finger, allowing for even more comfortable rolling of the ring on and off. Preferably, the entire ring band can be covered or studded with hollow spheres. Such an embodiment allows for particularly effortless crossing of the finger joint. The hollow spheres mounted on the ring band can be in contact with each other in the ring band's rest position, or arranged side by side without contact. If the ring band is subjected to a force that causes a change in size when the ring is put on or taken off, and this increases the effective circumference of the ring band available outside the receiving element, the distance between the individual hollow spheres can increase.

[0021] In a preferred embodiment of the ring, the hollow spheres have a sphere diameter and are mounted on the ring rail in the rest position so as to be displaceable along a circumferential direction of the ring rail by at most half, preferably at most a quarter, of the sphere diameter.

[0022] This creates a ring that offers all the advantages mentioned above, yet despite the numerous hollow spheres mounted (and rotatable) on the ring band, its dimensional stability is comparable to that of solid (jewelry) rings, as the hollow spheres are densely packed along the band. This further increases user acceptance of such rings.

[0023] In a preferred embodiment of the ring, the receiving element is designed to receive a stone setting or as a stone setting, the stone setting preferably being designed to receive a gemstone with a round, radiant, drop, marquise, briolette, Asscher, baguette, princess, cushion, oval, kite, heart, trillion or emerald cut.

[0024] This makes it possible to equip the ring itself with comparatively large or heavy gemstones of various cuts without affecting the handling described above and / or the rolling effect.

[0025] Preferably, the receiving element has an opening on its underside – facing the finger when the ring is being worn as intended – to facilitate easier cleaning of a gemstone held in the setting. The other end of the ring band can also be accessed from the outside via this opening.

[0026] In a preferred embodiment of the ring, the receiving element is designed to receive electronic components and is preferably designed on one of its outer sides to receive a stone setting, as a stone setting and / or to receive a stone setting.

[0027] This makes it possible to equip the ring with additional functionality. In particular, according to this embodiment, the ring can be designed as a smart ring. A smart ring is understood to be a compact, wearable electronic device that combines mobile technology with additional functions. Such devices, which are usually positioned and worn on the user's finger like a conventional ring, enable functions such as mobile payment, access control, gesture control, as well as activity tracking or monitoring of bodily functions. Smart rings can be connected to smartphones or other devices to interact with them. Smart rings can also communicate with cloud-based systems or perform independent tasks.

[0028] The smart ring according to this embodiment can be equipped with a variety of sensors and technologies that enable it to collect and process various data. It can connect to a smartphone or other devices via Bluetooth or NFC. Through its connection to a smartphone, the smart ring can receive notifications such as calls, text messages, or app alerts and discreetly notify the user through gentle vibrations. The smart ring can also include sensors for monitoring heart rate, sleep, and steps to collect, monitor, and analyze health and fitness data. Furthermore, the smart ring can allow the user to perform simple actions through hand gestures, such as muting calls or navigating through documents or presentation slides displayed on another device.

[0029] Since the sensors of a smart ring require close skin contact to function reliably, such rings should fit particularly snugly, yet still be comfortable to wear and not cause pressure points or pain. The ring according to this preferred embodiment allows for the integration of electronic components (such as batteries, sensors, microchips, processing and communication units, microphones, cameras) within the receiving element; at the same time, a particularly secure hold and a snug fit are achieved by using a significantly smaller ring size due to the movable mounting of the second end of the ring rail on the receiving element and the spring action of the ring rail, optionally enhanced by the hollow spheres rotatably mounted on the ring rail. This is unlike conventional smart rings (which must always be sized to fit over the finger joint). This ensures ideal skin contact for the sensors housed in the receiver and guarantees reliable data acquisition, particularly through the electronic components within the receiver. Even with very thick finger joints, the sensors maintain the necessary skin contact. Furthermore, even in cold or wet conditions, the ring is prevented from slipping off.

[0030] The size variability described above, particularly with regard to smart ring designs, offers the distinct advantage that a ring of a specific size (in the resting position of the band) can accommodate a range of conventional ring sizes. For example, a size S (Small) ring can be worn by individuals with ring sizes 54, 55, or 56. This significantly simplifies logistics, especially for smart ring designs typically sold online, as it drastically reduces the number of returns due to incorrect sizing. This also results in substantial cost savings.

[0031] According to a preferred embodiment of the ring according to the invention, the receiving element is designed on an outer side to receive a stone setting and / or to receive a stone setting, or is designed as a stone setting.

[0032] Particularly when the receiving element is designed as a housing for electronic components, especially sensors and microchips, this embodiment allows the primarily functional ring to be upgraded to a more sophisticated piece of jewelry. For example, an upper outer surface – facing away from the user's finger during operation – can be fitted with a stone setting or be designed as such. Alternatively or additionally, an inner outer surface – facing the user's center of the body during operation (i.e., proximally oriented) and / or an outer surface – facing away from the user's center of the body during operation (i.e., distally oriented) – of the receiving element can be designed to receive or be fitted with a stone setting.This can increase public acceptance of smart rings, enabling automated early detection of medical emergencies—especially among elderly users—and rapid alerting of emergency services through vital sign monitoring. Furthermore, the various possible casing designs, in combination with a potential [missing information], allow for [missing information]. Gemstone settings allow for a wide variety of design ideas. Smart-Ring versions of the ring can be upgraded to a fully-fledged piece of jewelry through the addition of gemstones.

[0033] In a preferred embodiment of the ring, it is provided that an underside of the receiving element is curved, wherein preferably the curvature of the underside of the receiving element corresponds at least partially to a curvature of the ring rail.

[0034] This further improves the ring's comfort, especially since the underside of the receiver is now adapted to the shape of the user's finger. This offers ergonomic advantages when the ring is used as intended, i.e., when worn.

[0035] In a preferred embodiment of the ring, the receiving element, viewed in a cross-section of the ring, extends at least sectionally below a circle passing through the ring rail, with the underside of the receiving element preferably being arranged below the circle.

[0036] This ensures particularly close contact between the user's finger and the sensor element, especially the underside of the sensor element. This allows the sensor element to be held securely on the finger and prevented from slipping; this is particularly advantageous for smart ring versions of the ring, as sensors housed in the sensor element can record data with exceptional reliability.

[0037] In principle, the ring band and the setting can be made of precious metal. Any electronic components (in smart ring versions) can be encased in plastic and housed within the setting. Furthermore, manufacturing the ring band and setting from precious metal, and the option of incorporating a decorative element, such as one or more gemstones, within the setting, allows for a particularly high-quality ring.

[0038] In a preferred embodiment of the ring, the ring band is formed as a round wire, preferably made of 14-karat or 18-karat gold, in particular yellow or white gold, silver, platinum, or other precious metal alloys, wherein the round wire preferably has a diameter between 0.5 mm and 2.5 mm, and is particularly preferably 1 mm, 1.2 mm, 1.5 mm, or 1.8 mm. A round wire with a diameter of [missing information] is particularly preferred. The 1.5 mm diameter is crafted from 18-karat yellow gold. This allows for a particularly good spring action, making the ring especially comfortable to put on and take off.

[0039] The ring band, designed as a round wire, exhibits the desired spring action to a particularly high degree. A diameter of 1.5 mm is especially advantageous. Furthermore, the round wire design allows the ring to rest on the user's finger at only one point (essentially a point running along the circumference of the finger), rather than across a larger area as with other rings. This improves the ring's handling, making it even easier to put on and take off. Moreover, this preferred design allows for particularly high-quality manufacturing. In particular, the ring can be sold even in countries with strict hallmarking laws, as all parts of the ring are made of precious metal. Hallmarking refers to the stamping of a precious metal object.Hallmarks (markings) on precious metal objects indicate, for example, the fineness, the manufacturer, or the body that verified the object's fineness. Most countries have regulations mandating the application of certain hallmarks to precious metal objects. Therefore, depending on the regulations of the country in question, precious metal objects often bear one or more of the following hallmarks: fineness mark, manufacturer's mark, official hallmark or mark of an independent testing laboratory, year of manufacture, and responsibility mark. Furthermore, this material choice for the receiving element has proven particularly advantageous in terms of the required resistance to external forces. This reliably prevents deformation of the receiving element.Precious metals also do not corrode, so the rings – unlike rings containing steel springs or plastics – last virtually indefinitely. Furthermore, manufacturing them from precious metal(s) has the advantage that the rings according to the invention are particularly well-tolerated by allergy sufferers.

[0040] Further problems of the invention are solved by a vehicle, in particular a vehicle, or a lifting device comprising at least one ring, wherein the ring comprises an inner ring and balls rotatably mounted on the inner ring. In particular, the balls can be designed as hollow spheres and rotatably mounted about the inner ring.

[0041] The subject is therefore the use of a rolling ring, i.e. a ring comprising an inner ring and balls rotatably mounted on the inner ring, in particular hollow balls, but preferably several such rolling rings, in a vehicle and a lifting device. While the use of roller rings in a lifting device for lifting heavy objects, such as heavy pipes, offers the particular advantage that such objects can be inserted into the lifting device in a very simple way, secured against slipping out there, for example by using wedge-shaped locking elements, and subsequently held and transported more stably in the lifting device, such as a crane; the use of the roller ring in vehicles of all kinds, such as motor vehicles (e.g., combustion engine and electric vehicles), trucks, cars, amphibious vehicles, tractors, military vehicles (e.g., armored vehicles or tanks), lunar rovers, wheelchairs, walking aids (e.g., rollators), transport equipment and devices used in logistics (e.g., hand trucks, transport and conveying trolleys, warehouse and order picking trolleys), offers a multitude of advantages.

[0042] In principle, the rolling ring can be used on all types of vehicles wherever wheels are typically used. Depending on how the rolling ring is arranged on the vehicle, especially on a chassis, a wide variety of movements can be performed, giving the vehicle superior maneuverability compared to the prior art. In particular, the spheres movably mounted on the inner rings of the rings or rolling rings—which can be hollow spheres with openings or solid spheres with through holes—allow degrees of freedom of movement that could not be achieved in conventional vehicles, or only through complex additional technical devices.For example, a vehicle with a rolling ring resting on the ground can be moved in virtually all directions (between 0° and 360°, relative to any preferred direction) with virtually no turning radius by rotating the respective ball(s) movably mounted on the inner ring. This can be achieved either with conventional (auxiliary) drives or by a corresponding self-propulsion system of the rolling ring or the vehicle. For example, the balls can be magnetically driven. Alternatively or additionally, the rolling rings themselves can be mounted on the vehicle, particularly on a chassis, so that the entire rolling ring – analogous to a wheel – can be rotated clockwise or counterclockwise.This enables a particularly precise and space-saving alignment of the respective vehicle in relation to its environment, which is especially advantageous in connection with fully autonomous devices, such as logistics robots.

[0043] Furthermore, the use of rolling rings, particularly instead of conventional pneumatic tires, allows the vehicles according to the invention to be used under conditions where conventional pneumatic tires would fail. This is especially true when used in... In a vacuum, such as in the case of a lunar vehicle or rover, conventional pneumatic tires would outgas; however, vehicles whose undercarriage includes at least one, preferably several, rolling rings can be used without any problems. Lubricants, which would also outgas in a vacuum, can also be omitted.

[0044] The rolling rings, meaning both the inner ring and the balls mounted on it, can be made from a wide variety of materials, such as metal (e.g., steel, titanium, aluminum, copper, gold, or silver), plastic, rubber, or ceramic. Similar to a conventional (pneumatic) tire, some or all of the balls in a rolling ring can have a surface texture or profile. Light grooves and / or ridges can be used to ensure the balls roll as smoothly and quietly as possible, while more pronounced treads or structures with greater depth contribute to better handling in adverse road conditions, such as rain (aquaplaning). Furthermore, the (approximately "point-like") contact of the individual balls with a flat, hard surface generally reduces the risk of aquaplaning.

[0045] According to a preferred embodiment, the at least one ring, preferably each ring, is arranged on the vehicle for moving heavy loads. Accordingly, the ring(s) are installed in or on the vehicle in such a way that they can transmit the vehicle's movement. This represents an innovative use of rolling rings, especially since conventional wheels do not include rotatably mounted balls and therefore do not offer additional degrees of freedom, namely in the direction of movement of the balls. Thus, this type of vehicle is ideally suited for applications where conventional vehicles are unsuitable – for example, due to their turning radius.

[0046] According to a preferred embodiment, the at least one ring, preferably each ring, is a component of the chassis of the vehicle, in particular the vehicle. Vehicles with such chassis are not known from the prior art and offer novel maneuverability capabilities, especially due to the lateral movements they enable.

[0047] According to a preferred embodiment, several inner rings are joined or connected, particularly via several connecting elements, to form complex structures and utilize a rolling effect at different locations. Such a connection of several rolling rings, which connection can also be made, for example, via or by means of other parts of the By using a chassis, particularly effective contact with the surface on which the vehicle is to move can be ensured. The individual roller rings can also be articulated on the chassis or frame to allow for variable orientation and to adapt particularly well to varying surface conditions.

[0048] According to a preferred embodiment, several inner rings of different sizes are provided, preferably arranged concentrically, with these inner rings lying in one plane. Preferably, the inner rings of the individual roller rings can be connected via radially extending connecting elements. Alternatively, the individual roller rings, in particular their inner rings, can be attached (for example, by pivoting) to the chassis or running gear of the vehicle. This enables particularly stable mounting of the vehicle on the ground. For example, two roller rings can be provided, with an outer roller ring having a first inner ring with a first diameter and an inner roller ring having a second inner ring with a second diameter, the first diameter being larger than the second diameter. This allows for even more targeted and precise control.Movement of the vehicle is made possible because, for example, when the balls of the outer rolling ring are just off-contact with the ground in a desired angular range, the balls of the inner rolling ring in the same angular range—in the case of a desired forward movement around 0°—are indeed in contact with the ground and can thus transmit the desired movement. The individual rolling rings or inner rings of the individual rolling rings do not necessarily have to be arranged concentrically; it is also possible for several smaller inner rolling rings to be arranged within a larger outer rolling ring, for example, in the densest circular packing arrangement for the respective number of inner rolling rings.

[0049] According to a preferred embodiment, vertically stacked inner rings are connected to each other via vertical connecting elements.

[0050] According to a preferred embodiment, inner rings are arranged side by side in a plane, for example in a square configuration. The individual roller rings, or the inner rings of the individual roller rings, can be connected in pairs (to each other) via horizontal connecting elements, or, as described above, not directly to each other, but separately to the chassis or running gear, in particular by means of a pivot. In addition to square arrangements of, for example, four roller rings, other configurations are also possible. Other arrangements are conceivable, for example paired, triangular, pentagonal, or hexagonal arrangements. These result in particularly advantageous driving characteristics for corresponding vehicles.

[0051] According to a preferred embodiment, the at least one ring, preferably several rings, is arranged horizontally and connected to the chassis or suspension of the vehicle, for example by means of a pivot. This represents only one of the conceivable ways in which the rolling ring can be used for propulsion in a vehicle (as illustrated by the embodiments and advantages described above). Another variant consists of arranging the rolling ring(s) vertically on the vehicle, analogous to the arrangement of tires on a car. The rolling rings can also be connected to the chassis or suspension of the vehicle.In particular, the rolling rings may include a receiving element, such as a receiving ring arranged concentrically with the respective inner ring or a hub, to receive or be connected to the vehicle's wheel suspensions. The receiving element may be connected to the inner ring of the respective rolling ring via spacer elements, in particular via radially extending spokes, wherein no balls are provided at those points on the inner ring where the spacer elements engage. The spacer elements may be fixedly connected to the receiving element at one end or formed integrally with it. At the other end, the spacer elements may be connected to the inner ring, for example, via eyelets. Preferably, the spacer elements may have a circular cross-section, at least in sections; this also applies to the inner ring.Such embodiments make it possible to equip vehicles with rolling rings instead of conventional pneumatic tires. This not only enables movement in the direction of the rolling rings (i.e., in the direction of travel), namely by driving and adjusting the orientation of individual rolling rings, for example, the two front rolling rings of a vehicle equipped with two front and two rear rolling rings; but it also makes it possible to move the vehicle in the direction of rotation of the balls mounted on the inner rings. This allows for directions of movement that are essentially perpendicular to the aforementioned direction of travel, for example, to enable the vehicle to be parked directly into a parallel parking space. For this purpose, the vehicle can be equipped with a lateral drive, which can be implemented, for example, by a drive, preferably magnetic, of the individual balls of the rolling rings.Additionally or alternatively, the side drive can also be implemented by a laterally pointing auxiliary wheel, which can also be designed as a rolling ring. Such an auxiliary wheel, for example, is used in the... The fact that the wheel can be attached to the chassis in the center of the vehicle and that its axis of rotation can point in the longitudinal direction of the vehicle, and is also designed as a rolling ring, has the additional advantage that the additional wheel does not have to be retracted or folded in during regular ferry operation, since the rolling ring can rest on the ground only with balls movably mounted on the inner ring and these balls can follow or carry out the directions occurring in the course of regular ferry operation (i.e. the directions of movement).

[0052] To dampen vibrations occurring during regular ferry operation, i.e., movement in the direction of travel, or to prevent them from being (fully) transmitted to the chassis or running gear, it can be advantageous to provide damping elements. According to a preferred embodiment, the chassis is mounted, preferably elastically, on and / or at least on one ring, preferably all rings.

[0053] Regardless of whether the rolling ring(s) are arranged horizontally or vertically on the vehicle, it can be advantageous if the chassis or running gear is rotatably connected to at least one ring, preferably all rings. This allows the drive of each rolling ring itself – in addition to any drive of the rotating balls within each rolling ring. If the rolling ring(s) are arranged vertically on the chassis or running gear, this allows the vehicle to operate analogously to a conventional vehicle with pneumatic tires. If, on the other hand, the rolling ring(s) are arranged horizontally, this allows the chassis to rotate.

[0054] In general, it can be said that the use of one or more rolling rings on a vehicle in rough terrain, such as sand, gravel, or mud, offers the advantage that the balls of the rolling rings sink a certain distance into the ground, thus improving power transmission to the uneven surface. This can also lead to improved handling on steep inclines or declines.

[0055] Vehicles or vehicles whose chassis or undercarriage includes one or more roller rings or wheels benefit from improved maneuverability. In particular, such vehicles can also be moved or shifted laterally. Brief description of the characters

Ways to implement the invention

[0057] Figures 1, 2, 4 and 5 show the ring according to the invention in a first embodiment. The ring initially comprises a ring rail 1 and a receiving element 2.

[0058] The ring rail 1 is essentially circular in shape, with a first end 5 of the ring rail 1 and a second end 6 of the ring rail 6 separated from each other. are spaced apart. In this respect, one can speak of an interrupted, circular ring band 1. In the embodiment shown in FIGS. 1 to 4, the receiving element 2 is essentially conical and designed to receive at least one decorative element 3 in the form of a brilliant-cut gemstone. The receiving element 2 is therefore a gemstone setting. In other embodiments, however, the receiving element can (additionally or alternatively) also be designed to receive electronic components 4 (see FIGS. 7a to 7d).

[0059] As can be seen in Figures 6a to 6j, the receiving element 2 can assume different shapes, depending on the type and shape of the gemstone (or more generally, the decorative element 3) to be received. For example, the decorative element 3 can be a gemstone with a round, radiant, pear, marquise, briolette, Asscher, baguette, princess, cushion, oval, kite, heart, trillion, or emerald cut. For this purpose, the receiving element 2 can be, for example, circular (Figures 6a and 6b), oval (Figures 6c and 6d, 6e and 6f, 6i and 6j), or square (Figures 6g and 6h) – each with respect to a circumferential edge, which circumferential edge is particularly evident in a top view in Figures 6a, 6c, 6e, 6g, and 6i. The corresponding sectional views in Figs. 6b, 6d, 6f, 6h and 6j illustrate the corresponding cone shapes with different flank angles between a lateral surface 9 and a bottom surface 10 of the receiving element 2.

[0060] In embodiments of the ring with a receiving element 2 designed to accommodate electronic components 4, essentially the same shapes of receiving elements 2 can be used as those employed in the gemstone settings described above. Preferably, however, the receiving elements 2 of such embodiments, also referred to as "Smart Rings," are designed with a greater longitudinal extent and thus with a longer underside 10 in order to maximize the contact area of ​​the receiving element 2 with the user's skin. This is particularly advantageous in embodiments of the ring with sensors for monitoring vital functions, as it allows the sensor measurements to be carried out more reliably and accurately (see Figs. 7a and 7b, where the electronic components 4 are formed by sensors arranged in the area of ​​the underside 10 of the receiving element 2).In principle, however, even in "Smart Ring" embodiments, in addition to the electronic components 4, decorative elements 3 can be arranged in, on, or around the receiving element 2 to upgrade the "Smart Ring" to a fully functional jewelry ring. Such embodiments, also referred to as "Smart Jewel," are shown in Figures 7c and 7d. Figure 7a shows a sectional view of a Smart Ring in a vertical section. Fig. 7b shows a horizontal section of this ring, with the section plane passing through the receiving element 2 above the ring band 1. Fig. 7c shows a top view of a ring in a smart-jewel design; Fig. 7d shows a sectional view of this ring, with the vertical section plane, from the viewer's perspective, passing through the receiving element 2 in front of the jewelry element 3.

[0061] The functioning of the ring according to the invention can be described particularly clearly with reference to Figures 4 and 5. Because the first end 5 of the ring rail 1 is rigidly connected to the receiving element 2 and the second end 6 of the ring rail 1 is movably mounted in or on (here: in) the receiving element 2, the ring rail 1 is elastically deformable (or such deformability can be utilized). This deformability allows the ring size to change when the ring rail is subjected to a corresponding force. In other words, the ring rail 1 is resiliently mounted on the receiving element 2.

[0062] For this purpose, the first end 5 can be (laser-)soldered to the receiving element 2, in particular to an inner surface of the receiving element 2, and the second end 6 can be passed through a through-opening 7 of the receiving element 2 and arranged inside the receiving element 2. The ring rail 1 is thus mounted on the receiving element 2 in such a way that pulling the ring rail 1 (or an end section 11 of the ring rail 1 located in the receiving element 2) out of the through-opening 7 causes a change in ring size, in that the ring size increases. The second end 6 moves towards the through-opening 7. Such a movement can be caused by a radially outward force acting on the ring rail 1, which is the case, for example, when the ring is pushed over a finger joint of a user's finger during putting on or taking off and the finger has a larger diameter (or...) in the area of ​​the finger joint.The ring has a circumference that is greater than the inner diameter (or inner circumference) of the ring. This causes the ring rail 1 to be pushed outwards, resulting in a change in ring size (towards a larger ring size) due to the ring rail 1 being mounted to move on one side. An end section 11 of the ring rail 1, located inside the receiving element 2 in a rest position (where the ring rail 1 is not subjected to a force causing a change in ring size, see approximately Fig. 5), comprises the second end 6, which is formed here by a cross-sectional expansion 8. A spacer section 12 of the ring rail 1, extending between the cross-sectional expansion 8 and the through-opening 7 in the rest position, is responsible for the change in ring size towards a larger size. Ring sizes are available. For example, the ring size can be increased by a maximum of one ring size (measured as the inner circumference of the ring band in mm) if the spacer section 12 has a length of 1 mm. For a ring size increase of up to two sizes, the length of the spacer section 12 must be 2 mm, and for a ring size increase of up to three or even more sizes, the length of the spacer section 12 must accordingly be 3 mm or even 4 mm. As soon as this outward force ceases, for example, after passing the finger joint, the elastic deformation of the ring band 1 results in a restoring force, which returns the ring band 1 to a rest position. The rest position is defined as the position in which the ring band 1 is located when no forces that cause a change in ring size act on the ring band (shown in Fig. 4).This restores the original (smaller) ring size. The movement of the ring rail 1, which occurs during the ring size change, is indicated by the double arrow in Fig. 5.

[0063] In the illustrated embodiment, the second end 6 of the ring rail 1 is formed by the cross-sectional extension 8, which forms a stop to limit the movement of the ring rail 1 in the event of a change in ring size towards larger ring sizes and to prevent overstretching of the ring rail 1. The diameter of the cross-sectional extension 8 is larger than the diameter of the through-opening 7.

[0064] Fig. 8a shows an embodiment of the ring in a jewelry ring design (comprising the jewelry element 3) with hollow spheres 13 rotatably mounted on the ring band 1. Figs. 8b and 8c show further embodiments of the ring in a smart ring design (comprising the electronic components 4) with hollow spheres 13 rotatably mounted on the ring band 1. Figs. 8d and 8e show further embodiments of the ring in a smart jewel design (comprising the jewelry element 3 and the electronic components 4) with hollow spheres 13 rotatably mounted on the ring band 1.

[0065] The rotatably mounted hollow spheres 13 on the ring rail 1 create a rolling effect, which makes putting on and taking off the ring even more convenient. In the rest position of the ring rail 1 shown, in which the ring rail 1 is not subjected to a force that would cause a change in ring size, the hollow spheres 13 are arranged side by side and rotatably on the ring rail. The hollow spheres 13 can contact each other, but they are not pressed together in such a way as to restrict or prevent their rotation. The ring can be put on and taken off with ease. The ring is supported on the finger via the hollow spheres 13 or guided along the finger, thus enabling an even more comfortable rolling up and down of the ring.

[0066] In the embodiment shown in Fig. 8a, the entire ring rail 1 is covered or fitted with hollow spheres 13. This allows for particularly effortless passage over the finger joint.

[0067] Figures 9 to 18 show embodiments in which one or more rings 201 can be used in a vehicle 206 or in a lifting device 209.

[0068] Fig. 9 shows the ring 201 (also called a rolling ring). On an inner ring Several balls 205 – here, a total of 18 – are mounted on the inner ring 202, and in the illustrated embodiment, these balls 205 are designed as hollow spheres. The balls 205 are arranged on the inner ring 202 such that they are rotatable around the inner ring 202. Additionally, the balls 205 can also be displaceable along the inner ring 202. Each hollow sphere 205 has two bores (not shown) through which bores of the inner ring 202 pass. The bores are opposite each other, so that the inner diameter of the bores must be larger for small ring sizes or when the inner ring 202 is strongly curved than for larger ring sizes or a less curved inner ring 202, in order to prevent jamming and / or blocking of the hollow spheres.Between the individual hollow spheres, there is no or only a minimal gap (except in the area of ​​the eyelets described below) – just enough to prevent the spheres 205 from tilting and to ensure their free rotation. In Figures 10 to 17, the path of the inner ring 202 is indicated, although the inner ring 202 runs through the individual spheres 205 and is therefore not visible in views that are not sectional. The ring 201 can also include a hub 203, which is arranged concentrically within the inner ring 202. In the illustrated embodiment, the hub 203 is hollow and cylindrical. In particular, the rolling ring 201 can be connected to a wheel suspension of the vehicle or vehicle 206 via the hub 203 – similar to a wheel.The hub 203 can be connected to the inner ring 202 of the rolling ring 201 via spacer elements, in particular via radially extending spokes 204, wherein no balls 205 are provided at those points on the inner ring 202 where the spokes 204 engage, or the balls 205 are spaced apart from one another so that the spokes 204 can engage the inner ring 202. For this purpose, the ends of the spokes 204 that are attached to the inner ring 202 can be designed as eyelets. At an opposite end, the spokes 204 can be fixedly connected to the hub 203 or formed integrally with the hub 203. This creates a rolling ring, which is advantageous in a vehicle. 206 can be used. Corresponding vehicles 206 or vehicles are shown schematically in Figures 10 to 17.

[0069] Fig. 10 relates to a vehicle 206, in which only the chassis of the vehicle 206 is shown (the frame is not shown). In this vehicle 206, four roller rings 201 are arranged vertically and connected to the wheel suspensions of the chassis. In this respect, the chassis resembles conventional chassis, except that the pneumatic tires usually used have been replaced by a corresponding number (here: four) of roller rings 201. By rotating all the roller rings 201, for example via a front-end drive that drives only the two front roller rings 201, and optionally by adjusting the steering position of one, several, or all of the roller rings 201, the vehicle can be moved in different directions of travel – as is also the case with known vehicles with pneumatic tires. These directions of travel are indicated in Fig. 10 by the first directional arrows 211.Due to the rotatability of the individual spheres 205, the vehicle can also perform lateral movements, which are indicated by the second directional arrows 212. This lateral movement can be mediated either by a separate drive for the individual spheres 205 or by an additional wheel 207. The additional wheel 207, which can also be designed as a rolling ring 201, can also be arranged vertically, but essentially transversely to the (other) rolling rings 201 on the vehicle. To mediate the lateral movement, (only) the additional wheel 207 needs to be driven. The other rolling rings 201 then only need to be brought into the desired steering position; the freely rolling spheres 205 then enable the lateral movement.

[0070] Other vehicles 206 according to the invention can comprise rolling rings 201 – namely one or more – in a horizontal orientation or arrangement. Such vehicles 206 are shown schematically in Figures 11 to 14, 16 and 17.

[0071] Fig. 11 depicts a vehicle whose chassis is only schematically indicated by a boundary line. The vehicle's chassis is not shown here, but can be designed analogously to that of Fig. 10. Unlike in Fig. 10, the four rolling rings 201 of the vehicle shown in Fig. 11 are arranged horizontally, so that, in principle, all spheres 205 of the rolling rings 201 can rest on the respective surface, such as a road. Movements of such vehicles—whether in the directions of travel indicated by the first directional arrows 211, or in the lateral directions indicated by the second directional arrows 212—are primarily mediated by the separately rotating or rotatable spheres 205, which are held on the inner rings 202 of the individual rolling rings 201. Furthermore, it is also possible that It is provided that the rolling rings 201 themselves - either individually (as a whole), or as a unit of the four rolling rings 201 connected to each other via connecting elements 208 (see Fig. 15) - are rotatable, thereby enabling further movements to be carried out.

[0072] Figures 12, 14, and 16 depict vehicles 206, which can be designed, for example, as personal transportation, transport, and / or sports equipment, similar to a skateboard or an electric unicycle. The chassis, indicated only schematically by a boundary line, can, for example, be designed as a platform on which one or more users can stand or sit. Such vehicles 206 can have their own propulsion, such as an electric motor; alternatively or additionally, these vehicles can be moved by foot power (by pushing off the ground with one leg).

[0073] Figures 13 and 17 relate to a vehicle 206, designed as a handcart, whose chassis is mounted on the ground via a horizontally arranged roller ring 201. The chassis and roller ring 201 can be rigidly connected to each other via connecting elements 208.

[0074] Fig. 18 relates to a lifting device 209 for heavy loads. A pipe 210, for example, can be attached to a hook 213 (e.g., of a crane). Roller rings connected by a belt can be used for this purpose, whereby the hub 203 and spokes 204 can be omitted in such roller rings. The roller rings used can be designed either as single roller rings (with one inner ring) or as multiple roller rings (here: double roller rings) with several (here: two) inner rings. The balls rotatably attached to the inner rings allow the load, for example, the pipe 210, to be easily slid onto and positioned in the lifting device. Under load, for example, when the load is lifted via the roller rings attached to the belt, the individual balls can lock and prevent the load or the pipe 210 from slipping out.Here, a ring with a ring rail 1 and at least one receiving element 2 for receiving a fastening element can also be used, in which a first end 5 of the ring rail 1 is rigidly connected to the receiving element 2 and a second end 6 of the ring rail 1 is movably mounted in or on the receiving element 2. Balls 205, 13 can again be rotatably mounted on the ring rail 1 in the manner described above.
