DECORATION DEVICE AND METHOD FOR PRODUCING A DECORATION DEVICE

Description

[0001] The invention relates to a decoration device and a method for producing a decoration device. State of the art

[0002] A variety of decorative devices are known. The decorative device, for example, has a viewing element or viewing window through which a cavity filled with a liquid can be seen. Decorative elements, such as gemstones, can be movably arranged in the cavity, so that when the decorative device is shaken, the decorative elements detach from the liquid and then sink back to the bottom.

[0003] A disadvantage of previously known decoration devices is that the liquid in the decoration device is often toxic or hazardous to health. If the liquid or vaporized liquid leaks or escapes from the decoration device, inhalation of the vaporized liquid and / or contact with the liquid can pose a health risk.

[0004] US 2006 / 105091 A1, WO 2009 / 037506 A1 and US 1,850,190 A each show decoration devices according to the prior art. Disclosure of the invention

[0005] The present invention is based on the object of providing a decoration device with a cavity visible from the outside, wherein the cavity is filled with liquid and movable decoration elements are arranged in the cavity, wherein the liquid is harmless to health.

[0006] This object is achieved by a decoration device according to claim 1 and a method according to claim 13.

[0007] In particular, the object is achieved by a decoration device comprising a cavity for receiving gemstones and / or precious stones, wherein the cavity is at least partially, in particular completely, filled with a liquid mixture, a transparent viewing element through which the cavity is at least partially visible, and at least one gemstone and / or precious stone, wherein the at least one gemstone and / or precious stone is arranged in the liquid mixture so as to be movable by a shaking movement, characterized in that the liquid mixture comprises glycerol and propanediol, in particular 1,2-propanediol.

[0008] The advantage of this is that the liquid mixture is harmless to health. This means that if the liquid mixture or part of it escapes from the decoration device, any risk to the health of people, in particular if parts of the vaporized liquid mixture are inhaled or if they come into contact with the liquid mixture, can be essentially ruled out. This even applies if, for example, a small child ingests part of the liquid mixture. The decoration device therefore has a very high level of safety. In addition, the two liquids in the liquid mixture have different viscosity values, so that by using different proportions (e.g. weight or volume) of the two liquids in the liquid mixture, the viscosity of the liquid mixture can be adjusted over a wide range. This makes it possible to create a variety of different types of decorative elements orDecorative stones can be used. In addition, the liquid mixture is chemically stable. The liquid mixture is also technically simple and cost-effective to produce. In addition, the liquid mixture creates a lens effect, so that the at least one decorative element appears optically enlarged in the liquid mixture. In addition, the specific density of the two liquids is lower than the specific density of conventional decorative elements or decorative stones, ensuring that the decorative elements or decorative stones do not float on the liquid mixture, which is undesirable, but sink to the bottom. The liquid mixture is also colorless, so that the visible color of the at least one decorative element is not changed. A further advantage is that the liquid mixture does not evaporate, does not form bubbles, and does not foam.In particular, the object is also achieved by a method for producing a decoration device, in particular a decoration device according to one of the preceding claims, with a liquid mixture in a cavity of the decoration device, the method comprising the following steps: providing the decoration device, the decoration device . a cavity for receiving gemstones and / or precious stones, wherein the cavity is at least partially, in particular completely, filled with a liquid mixture, a transparent viewing element through which the cavity is at least partially visible, and at least one gemstone and / or precious stone, wherein the at least one gemstone and / or precious stone is movably arranged in the liquid mixture by a shaking movement of the decoration device; and introducing the liquid mixture into the cavity of the decoration device, wherein the liquid mixture comprises glycerol and propanediol, in particular 1,2-propanediol.

[0009] The advantage of this process is that the liquids are harmless to health, so that even when the liquid mixture is introduced into the cavity, any health risks are essentially ruled out. In addition, the decorative device produced ensures that if the liquid mixture or a part thereof escapes from the decorative device, any health risks to people are essentially ruled out, in particular if parts of the evaporated liquid mixture are inhaled or if there is contact with the liquid mixture. In addition, the liquid mixture creates a lens effect, so that the at least one decorative element appears optically enlarged in the liquid mixture of the decorative device produced. In addition, the specific density of the two liquids is lower than the specific density of conventional decorative elements.This ensures that the decorative elements or gemstones do not float on the liquid mixture, which is undesirable, but sink to the bottom. Furthermore, the process is technically simple and cost-effective. Another advantage is that the liquid mixture does not evaporate, does not form bubbles, and does not foam.

[0010] According to one embodiment of the decorative device, the liquid mixture has a viscosity and / or density such that the at least one gemstone and / or precious stone, after a shaking (or rotating) movement, sinks into the cavity due to gravity in the liquid mixture at a predetermined sinking speed. This is advantageous in that the effective force acting on the decorative elements in the liquid mixture due to gravity is particularly low. This is advantageous in that the decorative elements sink particularly slowly. This creates a snowflake effect.

[0011] According to one embodiment of the decorative device, the mixing ratio between glycerin and propanediol, in particular 1,2-propanediol, is such that the viscosity of the liquid mixture is adapted to the at least one gemstone and / or precious stone. This allows the sinking speed of the at least one decorative element to be adjusted to a desired value in a technically simple manner. This reliably prevents the decorative element from sinking too quickly.

[0012] According to one embodiment of the decoration device, the weight fraction of glycerin in the liquid mixture is between approximately 25% and approximately 50%. One advantage of this is that the viscosity of the liquid mixture is particularly high. Thus, decorative elements or gemstones with a particularly high density can be used, yet they still sink slowly in the liquid mixture.

[0013] According to one embodiment of the decoration device, the weight fraction of glycerin in the liquid mixture is between approximately 10% and approximately 25%. The advantage of this is that the viscosity of the liquid mixture is particularly low. Thus, decorative elements or gemstones with a particularly low density can be used, yet still sink within a reasonable period of time (e.g., within approximately 10 seconds or approximately 20 seconds).

[0014] According to one embodiment of the decorating device, the weight fraction of glycerin in the liquid mixture is between approximately 1% and approximately 10%. This has the advantage that the viscosity of the liquid mixture can be very low.

[0015] According to one embodiment of the decoration device, the weight fraction of glycerin in the liquid mixture is between approximately 10% and approximately 12%, and the weight fraction of propanediol, in particular 1,2-propanediol, in the liquid mixture is between approximately 85% and approximately 90%, in particular between approximately 88% and approximately 90%. An advantage of this is that the liquid mixture has a very low viscosity, so that light decorative elements sink slowly to the bottom in the liquid mixture.

[0016] According to one embodiment of the decoration device, the liquid mixture consists exclusively of glycerin and propanediol, in particular glycerin and 1,2-propanediol. This is advantageous in that it ensures that no chemical reactions occur in the liquid mixture. This ensures the longevity of the decoration device.

[0017] According to one embodiment of the decorative device, the visible element is connected to a recess in a rear wall of the decorative device. This is advantageous in that the visible element can be attached easily and securely. This prevents the liquid mixture from escaping from the cavity in a simple and reliable manner.

[0018] According to one embodiment of the decoration device, a closable opening for introducing the liquid mixture into the cavity is formed in a base and / or roof of the decoration device. This allows for technically simple introduction of the liquid mixture into the cavity. Furthermore, the opening is not located in the field of view through the viewing element.

[0019] According to one embodiment of the decorative device, a rear wall of the decorative device has a curved shape. This is advantageous in that the cavity can be particularly large, so that the decorative elements hardly come into contact with each other or barely touch each other during their movement. As a result, the movements of the decorative elements essentially do not interfere with each other.

[0020] According to one embodiment of the decorative device, a decorative figure is arranged in the cavity. This is advantageous in that the decorative figure is protected from the environment by the liquid mixture. Thus, the decorative figure can also be made of or comprise a sensitive material. In particular, the decorative figure can, for example, be made of or comprise a material that rusts upon contact with oxygen.

[0021] According to one embodiment of the method, a viscosity and / or a density of the liquid mixture is adjusted by weighting the weight proportions of the glycerin and the propanediol, in particular the 1,2-propanediol, in the liquid mixture such that the at least one gemstone and / or precious stone sinks into the cavity at a predetermined sinking speed after a shaking movement due to gravity in the liquid mixture. One advantage of this is that the effective force acting on the decorative elements in the liquid mixture due to gravity is adjustable. The advantage of this is that the decorative elements can sink particularly slowly.

[0022] According to one embodiment of the process, the liquid mixture consists exclusively of glycerol and propanediol, in particular of glycerol and 1,2-propanediol.

[0023] Preferred embodiments are set out in the dependent claims. The invention is explained in more detail below with reference to a drawing of an embodiment. Fig. 1 is a front view of an embodiment of the decoration device according to the invention; Fig. 2 is a perspective rear view of the decoration device of Fig. 1 ; Fig. 3 a side view of the decoration device from Fig. 1 ; Fig. 4 an exploded view of the decoration device from Fig. 1 ; Fig. 5 another exploded view of the decoration device from Fig. 1 ; Fig. 6 another exploded view of the decoration device from Fig. 1 ; Fig. 7 an exploded view of the main component of the decoration device from Fig. 1 ; and Fig. 8-11Views of the visible element of the decoration device from Fig. 1 .

[0024] In the following description, the same reference numbers are used for identical and equivalent parts.

[0025] Fig. 1 shows a front view of an embodiment of the decoration device 10 according to the invention. Fig. 2 shows a perspective rear view of the decoration device 10 from Fig. 1 . Fig. 3 shows a side view of the decoration device 10 from Fig. 1 . Fig. 4 shows an exploded view of the decoration device 10 from Fig. 1 . Fig. 5 shows a further exploded view of the decoration device 10 from Fig. 1 . Fig. 6 shows a further exploded view of the decoration device 10 from Fig. 1 . Fig. 7 shows an exploded view of the main component 40 of the decoration device 10 from Fig. 1 . Fig. 8-11 show views of the visible element 20 of the decoration device 10 from Fig. 1 .

[0026] The decoration device 10 is in Fig. 1 or Fig. 2 designed as a pendant. For this purpose, the decorative device 10 has a fastening recess 80 near its upper tip or in the end element 70 or the decorative element. A chain or the like can be pulled through the fastening recess 80. Using the chain, the decorative device 10 can be worn around the neck, for example.

[0027] The decorative device 10 can alternatively be, for example, a (finger) ring, a necklace such as a pendant, a necklace, or a jewelry clasp. It is also possible for the decorative device 10 to be an earring such as an earring, a hoop earring, an ear stud, or a hoop earring pendant. Furthermore, it is conceivable for the decorative device 10 to be an arm jewelry such as a bracelet, a flexible bracelet, a bangle, or an anklet. Further possibilities are for the decorative device 10 to be a cufflink, a brooch, a hair accessory, a key ring, a belt buckle, a bag charm, a lamp, a perfume bottle, or a cosmetic container.In addition, the decorative device 10 can be a writing instrument, a mobile phone or other electronic device, a mobile phone case, an application on an accessory, a timepiece such as a wristwatch, a pocket watch or a beverage container or a closure for a beverage bottle or a furniture accessory or the like.

[0028] The decorative device 10 comprises a main component 40 and a viewing element 20. The viewing element 20 is transparent. In the drawings, the viewing element is not shown transparent for illustrative purposes. The main component 40 is designed to be connected to the viewing element 20. A central part of the main component 40 forms a rear wall 45 of the decorative device 10, which is visible from the outside through the viewing element 20. The upper part of the main component 40 projects forward and forms a type of roof 41. The lower part of the main component 40 also projects forward and forms a type of floor 50.

[0029] The decorative device 10 has a circumferential contact area that is in contact with the visible element 20. The contact area is designed as a recess 60, 62 at least in the two opposite lateral areas of the main component 40, which each connect the roof 41 to the base 50. This means that in the lateral areas of the main component 40, a part of the main component 40 protrudes into the area surrounded by the visible element 20. The visible element 20 is thus not located in a socket, but rests on outer surfaces of the main component 40. The contact area can also be designed as a recess 60, 62 or setback all the way around.

[0030] The rear wall 45 is not flat, but has a curved shape. Both the outer surface (surface facing away from the cavity) of the rear wall 45 and the inner surface (surface facing the cavity) of the rear wall 45 are curved. From left to right in Fig. 1 The rear wall 45 has a curved shape. The curve points away from the visible element 20, i.e., the turning point of the curved rear wall 45 is farther away from the visible element 20 than the other areas of the rear wall 45. The thickness of the rear wall 45 varies at different points or locations.

[0031] The base 50 has a recess 49 in its center on the side facing the visible element 20. The visible element 20 has a complementary shape, ie, the visible element 20 has a tapered projection 25 on its lower side.

[0032] The visible element 20 also has a curved shape. The curved shape of the visible element 20 is designed corresponding to or similar to the curved shape of the rear wall 45, resulting in an egg-shaped outer shape of the decorative device 10. The egg-shaped outer shape has few to no sharp edges (except for the end element 70 or the decorative element).

[0033] The material of the viewing element 20 can comprise or consist of plastic, acrylic glass, genuine glass such as borosilicate glass, sapphire glass, crystal glass, silicon glass, or glass with a special vapor coating. It is also possible for the material of the viewing element 20 to comprise or consist of soft and / or elastic materials such as silicone.

[0034] A cavity 30 is formed between the rear wall 45, the roof 41, the floor 50, and the visible element 20. The cavity 30 is bounded by the rear wall 45, the roof 41, the floor 50, and the visible element 20.

[0035] A liquid mixture is arranged in the cavity 30. The cavity 30 is completely filled with the liquid mixture. Completely filled means that essentially no air bubbles are present in the cavity 30. However, it is also conceivable that a small air bubble is present, e.g., less than 1% of the volume of the cavity 30 is not filled with the liquid mixture.

[0036] The liquid mixture comprises glycerin (HOCH 2 CH(OH)CH 2 OH; CAS 56-81-5) and propanediol. Specifically, the liquid mixture comprises glycerin and 1,2-propanediol (CAS 57-55-6). It is also possible that the liquid mixture comprises glycerin and 1,3-propanediol (CAS 504-63-2). It is also conceivable that the liquid mixture comprises glycerin, 1,2-propanediol, and 1,3-propanediol.

[0037] It is possible that the liquid mixture contains no other components besides glycerin and propanediol, in particular 1,2-propanediol. However, it is also conceivable that the liquid mixture contains other components besides glycerin and propanediol or 1,2-propanediol.

[0038] For example, in addition to glycerol and propanediol or 1,2-propanediol, the liquid mixture may contain precious metal powder, colloidal precious metal, fluorescent particles or other nanoparticles.

[0039] It is also possible that color pigments, other colored liquids or solids or similar are added to the liquid mixture so that the decorative elements and / or the decorative figure are not seen in their original color, but in a different color or shade.

[0040] It is possible that the liquid mixture contains thermochromic dyes (where the color depends on the temperature), photochromic dyes (where the color changes due to light or UV light), phosphorescent dyes (afterglow dyes), reflective dyes (e.g. with embedded metallic flakes), magnetic dyes (e.g. dyes with embedded magnetic particles that contain computer-readable information) and / or electrical dyes (where the color is changed by an electric field or an electric current) in addition to the glycerin and propanediol.

[0041] The two liquids have different viscosities. Thus, the viscosity of the liquid mixture can be adjusted to different values ​​depending on the proportion of glycerol and 1,2-propanediol in the liquid mixture.

[0042] Glycerin has a higher viscosity than 1,2-propanediol. Thus, the viscosity of the liquid mixture can be reduced by increasing the proportion of 1,2-propanediol in the liquid mixture. Likewise, the viscosity of the liquid mixture can be increased by decreasing the proportion of 1,2-propanediol.

[0043] Glycerin and 1,2-propanediol have different densities, so the density of the liquid mixture can be adjusted to the density of the decorative elements by appropriately changing the weight proportions of glycerin and 1,2-propanediol. In particular, the density of the decorative elements can be adjusted to be only slightly (e.g., approximately 1% or approximately 2%) higher than the density of the liquid mixture, so that the decorative elements sink slowly in the liquid mixture.

[0044] For example, the density of the liquid mixture can be adjusted to the density of diamonds used as decorative elements by adding appropriate amounts of glycerin and propanediol, particularly 1,2-propanediol, such that the density of the liquid mixture is less than approximately 5% below the density of the diamonds. This causes the diamonds to sink slowly or at a low rate in the liquid mixture.

[0045] The viscosity of the liquid mixture can also be adjusted depending on the size and / or shape of the decorative elements. For larger objects, the liquid mixture may have a higher viscosity.

[0046] Decorative elements are arranged in the cavity 30. The decorative elements are movably arranged in the cavity 30 or the liquid. The decorative elements can be gemstones. In particular, the decorative elements can comprise cut or uncut gemstones, such as rubies, diamonds, or emeralds. The decorative elements can contain fluorescent elements. The decorative elements can comprise one, two, three, four, or more than four decorative elements.

[0047] The decorative elements are arranged movably in the cavity 30. This means that the decorative elements can basically move freely within the cavity 30.

[0048] The decorative elements have a higher density than the liquid mixture, so that they sink downwards due to gravity, for example towards the bottom 50 when the bottom 50 of the decorative device 10 is at the bottom.

[0049] By applying a force or impact counter to gravity, the decorative elements are distributed within the cavity 30. This can be achieved, for example, by shaking or rotating, or by carrying the decorative device 10. The density of the decorative elements is usually only slightly (e.g., approximately 2%, approximately 5%, or approximately 10%) higher than the density of the liquid mixture, so that the decorative elements sink at a low speed in the direction of gravity. The decorative elements essentially float in the liquid mixture for a short time.

[0050] The time required for the decorative elements to descend from the uppermost point of the decorative device 10 to the lowermost point of the decorative device 10 can, for example, range from approximately 5 seconds to approximately 10 seconds. It is conceivable that the decorative elements may require several seconds to descend.

[0051] The base 50 has a closable opening 55. The opening 55 extends from the outside or the outer surface of the decoration device 10 through the main component 40 into the cavity 30 of the decoration device 10. The opening 55 serves to introduce or fill the liquid mixture into the cavity 30 of the decoration device 10. The two liquids can be introduced individually one after the other into the cavity 30 and mixed therein. It is also possible for the two liquids to be introduced into the cavity 30 already mixed as a liquid mixture. The opening 55 can be closed in a liquid-tight, in particular airtight, manner by means of a pin or screw 57, which is adapted to the opening 55, and by means of a sealing ring 56, which is arranged around the pin or screw 57.

[0052] The upper part of the base 50, which is in direct contact with the liquid mixture or which delimits the cavity 30, can be an independent or initially separate element of the decoration device 10. The base 50 can be hollow. A chip, an electronic component, an RFID and / or EMV chip, or the like can be present or inserted in the cavity. The chip or electronic component can wirelessly transmit information stored in the chip or component. For example, the information can include a serial number of the decoration device 10 or measures to prevent counterfeiting of the decoration device 10.

[0053] The weight fraction of glycerol in the liquid mixture can be between approximately 25% and approximately 50%. For example, the weight fraction of glycerol in the liquid mixture can be approximately 30% or approximately 40%. However, it is also conceivable that the weight fraction of glycerol in the liquid mixture is approximately 10% to approximately 25%, for example approximately 15% or approximately 20%. It is also possible for the weight fraction of glycerol to be between approximately 1% and approximately 10%, for example approximately 5% or approximately 8%. In particular, it is also conceivable for the liquid mixture to contain or consist of 8 parts by weight of propanediol, in particular 1,2-propanediol, and 1 part by weight of glycerol.

[0054] In each of these examples, the missing weight fraction of the liquid mixture to 100% can be completely made up by 1,2-propanediol. This means that, for example, with a weight fraction of glycerol of approximately 15%, the weight fraction of 1,2-propanediol is approximately 85%.

[0055] However, it is also possible that 1,2-propanediol only almost makes up the missing weight fraction to 100%. This means that the liquid mixture contains a small amount of another liquid. For example, with a weight fraction of glycerol of approximately 15%, the weight fraction of 1,2-propanediol can be approximately 14%, meaning that approximately 1% of the weight fraction of the liquid mixture is made up of one or more other liquids.

[0056] One or more decorative figures, abstract or concrete objects, representations, motifs, paintings, engravings in various materials such as precious metals, gemstones, diamonds, enamels, etc. can be arranged in the liquid mixture.

[0057] The decorative figure or objects in the liquid mixture are arranged such that the decorative figure or objects can be seen at least partially, in particular completely, from the outside through the viewing element. The decorative figure is usually attached directly or indirectly to the main component 40. In particular, the decorative figure can be attached to the base 50 of the decorative device 10. The decorative figure can be completely surrounded by the liquid mixture. This protects the decorative figure, in particular from air or oxygen.

[0058] It is also conceivable for the decorative device 10 to have self-luminous elements, e.g., LED elements. The LED elements can, for example, illuminate the cavity 30. It is also conceivable for the LED elements to be part of the decorative elements, i.e., for the LED elements to be movably arranged in the liquid mixture.

[0059] A closing element 70 or decorative element is arranged on the roof 41 of the decorative device 10. The closing element 70 has two pins. The closing element 70 has the shape of a tapered cone with an elliptical base. The two pins are inserted into two recesses in the main component 40 or the roof 41 of the main component 40 in order to connect the closing element 70 to the main component 40 or to fasten it thereto. The recesses run in Fig. 1 into the cavity 30. However, they can also be designed as blind holes.

[0060] The decoration device 10 is manufactured as follows: First, the main component 40 is manufactured or provided. Subsequently, the visible element 20 is connected to the main component 40 by means of adhesive or the like. A seal can be arranged between the visible element 20 and the main component 40. The liquid mixture is then introduced into the cavity 30 through the opening 55. The weight proportions of the glycerin and the 1,2-propanediol are or will be adapted to the decoration elements in such a way that the decoration elements move downwards (i.e. in the direction of gravity) in the liquid mixture at a low speed (e.g., approximately 5 seconds for a distance of approximately 10 cm) due to gravity. The opening 55 is then closed in a liquid-tight, in particular airtight, manner by means of the screw 57 and the sealing ring 56.At any time, the end element 70 is placed on or connected to the roof 41 of the main component 40. The decorative device 10 is now completely manufactured.

[0061] The decorative device 10 also has a decorative strip 47 on the bottom 50 on both sides of the recess 49, on which further decorative elements, e.g. gemstones, can be arranged.

[0062] The decoration device 10 is designed to decorate a person, an object or a room.

[0063] The decorative device 10 can, in particular, comprise metal or consist of metal. In particular, the decorative device 10 can comprise or consist of precious metal. For example, the decorative device 10 can consist of or comprise gold, a gold alloy, silver, a silver alloy, platinum, and / or a platinum alloy.

[0064] It is of course also conceivable that the liquid and / or the decorative elements are exchanged for another liquid and / or other decorative elements through the reversibly closable opening 55. List of reference symbols
