Description

[0001] Cover for mobile devices for fastening additional elements

[0002] Technical area

[0003] The invention relates to a cover for the back of smartphones and other mobile radio terminals, comprising

[0004] (a) a mechanical or magnetic fixing means attachable to the back; and

[0005] (b) a carrier releasably attachable to the fixing means.

[0006] Mobile devices, and especially smartphones, are manufactured in large numbers and offered by manufacturers with only a few design options, including different sizes and colors. In contrast to their external design, smartphones offer an extremely wide range of functionalities realized through software. This includes functionalities that were implemented by dedicated devices before the invention of the smartphone, such as notebooks, cameras, wallets, alarm clocks, recording devices, music players, etc. While the functionalities realized through software are very diverse, the external appearance is largely the same.

[0007] State of the art

[0008] Cases for smartphones and other mobile devices are well-known in the art. These cases, in addition to providing protection against damage, also adapt the external appearance to individual taste, fashion, and use. The cases are attached from the back. A snap-on mechanism or an elastic cover ensures a secure connection between the case and the mobile device. Some cases fold like a book, allowing one of the covers to be folded onto the front. Visible design elements of the smartphone are altered or concealed within the case.

[0009] It's now common practice to store various small items, such as bus tickets, receipts, ID cards, or banknotes, between the case and the back of the smartphone. This eliminates the need to carry a separate wallet, purse, or other items. Smartphones are typically valuable and are carefully guarded by the user, so even the small items attached to them are safe. To access them, the case is removed, the small item is inserted or removed, and the case is then replaced.

[0010] Many people pay attention to their appearance and the accessories they wear. Accessories are adapted to the respective situation, the clothing worn, etc. The appearance of the mobile device is adapted accordingly by using different protective cases. These are designed for protection, not as an accessory. The selection of protective cases is limited, and changing them is comparatively complex. Anyone who wants a wide selection of appearances for their mobile device must keep a correspondingly large number of complete protective cases. This is expensive.

[0011] Under the brand name Imagisnap, the website https: / / casebang.com / pages / imagisnap offers a protective case that wraps around the outer edge of the smartphone. It consists of a holder that can be attached to the back of the mobile device, into which an insert can be detachably inserted. A large number of different inserts are available. Each insert is made of plastic and printed with different motifs.

[0012] Apple Corp. markets chargers under the brand name MagSafe that are positioned correctly using a magnet integrated into the smartphone. The magnet is also used to charge a magnetically attached battery pack. The smartphone can also be charged using a charger in the form of a holder. It is also known to hold card holders to the smartphone using the magnet. The magnetic connection easily breaks, and the magnets are too weak for other applications. There are also applications using stronger magnets.

[0013] There are covers and protective cases for smartphones that offer hardware functionality beyond the functionality realized by software. DE202022000067U1 discloses a mobile phone case with protection against electromagnetic radiation. DE202016001292U1 discloses a mobile phone case with additional lighting. DE202020105329U1 discloses a protective case with a strap attached for carrying. DE202012013562U1 discloses a protective case with a speaker.

[0014] Each of these protective cases has only one functionality. Anyone who wants to add a different functionality to their phone will need to use a completely new protective case with different features.

[0015] Disclosure of the invention

[0016] It is an object of the invention to provide an arrangement of the type mentioned at the outset with which one or more design elements and / or functionalities can be implemented on a mobile radio terminal in a particularly cost-effective manner and new designs and / or functionalities can be added in a sustainable manner.

[0017] According to the invention, the object is achieved in that

[0018] (c) the fixing means is bonded with an adhesive; and

[0019] (c) one or more design elements and / or functionalities are attached to or integrated into the detachably insertable carrier.

[0020] The inventive solution uses an adhesive to adhere the fixing means to the back of the mobile terminal. Such a connection is very stable and allows for numerous functionalities. The fixing means can be formed by at least one magnet or a receptacle. The at least one magnet or the receptacle remains on the mobile terminal. Only the carrier is replaced. Accordingly, less material is required for the various designs and / or functionalities. This is more cost-effective and sustainable. The invention can also be implemented on smartphones that do not have an integrated magnet.

[0021] Various straps with different designs allow for customization based on fashion, use, and taste. For example, the strap design can be adapted to the design of the environment, events, handbags, suitcases, clothes, or other accessories by inserting a matching strap into the holder.

[0022] In one embodiment of the invention, the adhesive allows the fixing agent to be removed from the back of the mobile terminal without leaving any residue and without additional chemical or physical aids. For example, a removable adhesive strip can be provided to adhere the holder to the back. A removable fixing agent facilitates the separation of the components during recycling and the attachment of a new fixing agent if the existing one is damaged. It is understood that permanent bonding can also be used as an alternative.

[0023] In one embodiment of the invention, the carrier can be connected to the fixing means in a form-fitting manner and / or magnetically and / or by means of a locking mechanism. For example, the fixing means can comprise at least one magnet glued to the back of the mobile radio terminal, and the carrier can have, on the side facing the back of the mobile radio terminal, a recess with a metal strip for each of the magnets for positively receiving the associated magnet. The carrier is then connected to the fixing means in a form-fitting and magnetic manner. The metal strips in the recesses interact with the magnets. It is understood that, conversely, metal strips can also be glued to the back of the mobile radio terminal, and magnets can be provided in the receptacles on the carrier. Instead of metal strips, other metal geometries that enable a magnetic connection can also be used.

[0024] Alternatively, the fixing means can comprise a receptacle into which the carrier can be inserted and which has an edge projecting outwards perpendicular to the rear of the mobile terminal. In this case, the fixing means is designed as a mechanical fixing means. The edge holds the carrier in its lateral position. The edge can be manufactured in one piece as an integral component of the receptacle. This is particularly cost-effective. In particular, the carrier can be formed by an insert which can be inserted into the receptacle and which is flat on the receptacle side. It is inserted flat into the receptacle and rests completely on the inside of the receptacle. This has the advantage that the mobile terminal is only slightly thicker than without any cover.

[0025] The carrier can be held in the holder in any way possible, for example, by means of a hook-and-loop fastener or the like. In an advantageous embodiment of the invention, locking elements for locking the carrier into the holder or other fastening elements for securing the carrier in the holder are provided at the edge. A locking connection allows for quick and easy changing of the carrier with the design elements and / or functionalities. It is particularly advantageous if the carrier is slightly flexible and can be pushed under locking elements that protrude inward from the edge.

[0026] A first variant of the invention provides that the receptacle and / or the carrier have dimensions such that the narrow sides of the mobile radio terminal are exposed even when the cover is in place. For example, the receptacle can be flat on the side facing the rear of the mobile radio terminal, so that the narrow sides of the mobile radio terminal are exposed even when the cover is in place. Unlike known covers for smartphones, the primary goal of the present invention is not to protect the smartphone from damage, but to achieve a desired appearance or functionality. The exposed narrow sides accommodate the desire to change the appearance of the mobile radio terminal as far as possible only on the rear side and to leave the narrow sides visible unchanged.

[0027] In an alternative embodiment of the invention, the holder and / or the carrier have a decorative and / or protective edge on the side facing the rear of the mobile radio terminal, which covers the narrow sides of the mobile radio terminal. In particular, it can be provided that the decorative and / or protective edge on the holder is made of a different material than the rest of the holder. This decorative and / or protective edge can, for example, be made of precious metals or other precious materials, be designed in particularly distinctive colors of an association or company, or additionally perform a protective function. It goes without saying that the decorative and / or protective edge can also have functionalities, such as luminous strips.

[0028] The mount can completely or partially cover the back of the mobile terminal. In an advantageous embodiment of the invention, a recess for a camera or other sensors is provided in the mount and / or in the carrier. In this case, the camera is not covered. It is understood that a mount can also be provided that covers only part of the back of the mobile terminal.

[0029] In a specific embodiment of the invention, design elements in the form of flat leather, imitation leather, textile, metal, paper, cardboard, plastic, wood, and / or imitation wood overlays are attached to the carrier. The design elements can cover the carrier completely or partially. Different design elements can also be combined. The design elements can be patterned, provided with text and / or image elements, or have a uniform design. Fluorescent or phosphorescent materials can be used. This makes the carriers with the design elements suitable for advertising, as fan and / or merchandise items, for applying addresses, identification numbers, warning notices, and other information. The flat design ensures that the mobile terminal does not become significantly thicker.

[0030] In a further embodiment of the invention, it is provided that at least one functionality is realized on or at the carrier by means of one or more functional elements, which comprise:

[0031] Transceiver or transmitter, including RFID or NFC chip;

[0032] Lighting devices, including micro-LEDs or luminous surfaces, odor-emitting devices; one or more fastening elements, including hooks, brackets, and / or locking elements; decorative three-dimensional elements or figures;

[0033] Camera and / or lens assemblies and / or other optical attachments;

[0034] Holder for money and / or cards;

[0035] storage means for electronic information;

[0036] Energy storage means; and / or

[0037] Storage media for fluid or solid media.

[0038] For example, an RFID or NFC chip can be integrated directly into the carrier, glued to it, or applied in some other way. However, the chip can also be integrated into a chip card in the usual way, which in turn is connected to the carrier or held on the carrier. The chip can contain information that allows identity, access authorization, or similar to be determined.

[0039] The support and / or the edge can be equipped with illuminants. The illuminants can be powered by energy from a photocell, a rechargeable battery, the mobile phone device, or other energy storage device. However, the illuminant can also be fluorescent or phosphorescent.

[0040] In a further embodiment of the invention, an odor-emitting agent is provided. The odor-emitting agent can be activated by peeling off a protective film, or a reservoir is provided that contains the odor-emitting agent and can be refilled with it as needed. These can be in the form of perfumes, essences, herbs, and the like.

[0041] The carrier can also comprise one or more fastening elements, including hooks, holders and / or locking elements. Smaller items can be carried on these fastening elements. These include, for example, jewelry, pens, coins, bags, ribbons, chains and the like. The carrier can furthermore have decorative three-dimensional elements or figures. Such an element can, for example, be fastened in such a way that the element or figure itself or via a suitable intermediate piece is provided with a thread which interacts with a matching thread of a counterpart. The counterpart and the intermediate piece or the three-dimensional element can, for example, be arranged on different sides of the holder and connected to one another by an opening in the holder. In this way, a particularly strong connection is created.Advantageously, the counterpart is recessed into the side of the receptacle facing the mobile device, so that it does not protrude from the plane. The use of an intermediate piece has the advantage that various three-dimensional elements can be attached to it. Any type of detachable connection, particularly mechanical connections, such as snap-in connections, snap-in snap-in connections, or click connections, such as those commonly found in snap fasteners, can be used. If the opening is not needed, it can be closed with a small closure.

[0042] The carrier can also be equipped with camera and / or lens assemblies and / or other optical attachments. Lens assemblies and / or optical attachments, such as optical filters, distorters, or light amplifiers, can be arranged in front of the camera typically present in a mobile radio terminal. Such optics can easily enhance the camera or modify its properties as desired.

[0043] Another design provides a holder for money and / or cards. For example, cash in the form of coins or notes can be stored in a corresponding holder attached to the carrier.

[0044] Storage means for electronic information can also be provided on the carrier. Such a memory is, for example, a USB stick or a memory card. The memory can be connected wirelessly or wired to an input of the mobile terminal via a suitable interface. In this way, for example, additional storage capacity for videos or other large amounts of data can be added interchangeably without the need for complex data transfer. In a further embodiment of the invention, energy storage means are provided. This is particularly useful if it is foreseeable that the charging capacity of the mobile terminal will not be sufficient until the next charging option. The mobile terminal can then be charged using these energy storage means. Alternatively or additionally, the carrier is provided with photovoltaic cells.

[0045] In addition to electronic energy and information storage devices, storage devices for fluid or solid media can also be provided. These can house alcohol, disinfectants, medications, and the like.

[0046] The mount preferably has a honeycomb structure or other stabilizing structure. The mount can be designed to be permeable, like a grid. However, the stabilizing structure can also be molded onto the surface of a flat area. The stabilizing structure has the advantage of achieving the desired stability with less material consumption.

[0047] The present invention provides a modular system that allows the mobile radio terminal to have a wide variety of physical properties that were previously inaccessible or only accessible with considerable effort.

[0048] The mount should be attached to the back of the mobile device in such a way that a uniform finish is achieved, with the edge of the mount never protruding beyond the edge of the mobile device. A mounting aid can be used for this purpose. The mounting aid for mounting the mount described above on a smartphone or other mobile device comprises an open housing with a flat surface and an edge projecting forward from the surface. The dimensions are selected such that the mount assumes a clear position when inserted into the housing and is fixed in this position, so that the housing with the mount fixed in it can be placed over a mobile device with the open side.If the mobile device has the same dimensions on the back as the holder, the protruding edge of the mounting aid's open housing also encloses the mobile device in a unique position. When slipped over the holder, the holder and the mobile device are therefore positioned with high precision. An adhesive between the back of the mobile device and the holder ensures good adhesion, preventing them from slipping against each other or coming loose after the mounting aid is removed. Similarly, a mounting aid can be designed to adhere magnetic strips in the correct position.

[0049] To prevent the holder from falling out of the housing when slipping it onto the mobile device, an adhesive strip and / or other additional fixing device can be provided in the housing to secure the holder in place. The adhesive strip can be removed after successful installation through an opening in the mounting aid or together with the mounting aid.

[0050] Embodiments of the invention are the subject of the dependent claims. One embodiment is explained in more detail below with reference to the accompanying drawings.

[0051] Definitions

[0052] In this description and the appended claims, all terms have a meaning familiar to the person skilled in the art, which is explained in the technical literature, standards, and relevant websites and publications, especially lexical ones, for example, www.Wikipedia.de, www.wissen.de, or those of competitors, research institutes, universities, and associations, for example, Bitcom. In particular, the terms used do not have the opposite meaning to what the person skilled in the art would derive from the above publications. For example, the term "removably attached" refers to any arrangement that can be removed without causing damage during its intended use.

[0070] Description of the embodiments

[0071] Example 1: Fig.1-7 (mechanical fixing device)

[0072] The figures show a cover for mobile radio terminals, which consists of a mechanical fixing means in the form of a holder 10, a carrier 12, and a design element 14. Figure 1 is an exploded view of the cover and illustrates how it is assembled. The holder 10 essentially consists of a flat grid 13 with a honeycomb structure. The holder 10 is provided with an adhesive strip on its back. The adhesive strip is protected by a protective film. To apply the cover to the back of a mobile radio terminal 15, the protective film is removed, and the cover 10 is glued with its flat back to the back 17 of the mobile radio terminal 15.

[0073] Alternatively, an assembly aid described below can be used. The adhesive bond is stable and cannot detach from the mobile terminal 15 without external forces. However, the adhesive on the adhesive strips allows the cover 10 to be removed from the surface of the smartphone or other mobile terminal without the aid of chemical or mechanical means.

[0074] A mounting aid 52 is shown in Figures 2A, 2B, and 2D. The mounting aid 52 essentially consists of an open housing with a flat base 54 and an edge 56. The dimensions of the base 54 and the edge 56 are designed such that the receptacle 10 can be inserted into the housing and is precisely defined by the edge 56. An opening 58 is provided in the base 54. In the area above the opening 58, an adhesive strip 60 is fixed to the housing. When the receptacle 10 is inserted into the housing of the mounting aid 52, it adheres lightly to the adhesive strip 60. It cannot therefore fall out. The mounting aid 52 with the receptacle 10 can now be slipped over the mobile radio terminal 15. The receptacle 10 and the mobile radio terminal 15 are glued together with an adhesive. The adhesive strip 60 can be removed from the outside, and the mounting aid can be taken off.

[0075] In the present exemplary embodiment, the cover 10 is designed for a commercially available smartphone 15. It goes without saying that the lateral dimensions of the cover 10 are adapted to the size of the smartphone 15. Accordingly, larger covers can also be used for larger mobile radio devices, such as tablets or laptops. For mobile radio devices with one or more cameras 19, lights 21 and / or other sensors 23, a recess 28 is provided in the cover 10 so that these are not covered. A corresponding recess 30 is provided in the carrier 12 and a recess 32 in the design element 14. To protect the cameras 19, lights 21 and / or other sensors 23, the recess 28 in the cover 10 can optionally be provided with a transparent plate 25 made of glass or plastic. The plate 25 is inserted into the recess 28 of the holder 10 and fixed there.

[0076] Instead of a simple plate 25, an optical system can also be placed in front of the camera 19. This is illustrated as an example in Figure 5A. For this purpose, a plate 27 is used which has the same external dimensions as the plate 25. The plate 27 can be equipped with optical inserts, such as lenses 33 in a lens holder 34, filters, shutters, diaphragms 37 and the like. For this purpose, the plate 27 is provided in the area in front of the camera 19 with a recess and a thread, a plug connection or a bayonet lock 29, 35. Using the thread, the plug connection or the bayonet lock 29, 35, a housing 31 with the optical inserts 33 in a holder 34 can be screwed on, plugged on or fixed with a bayonet lock. In the present embodiment, depending on the application, various optical inserts can be used, which are attached interchangeably to the plate 27.The plate 27 is inserted with an edge 39 into the recess 28 of the holder 10.

[0077] The holder 10 rests with a flat surface on the back 17 of the smartphone 15. A peripheral edge 16 is formed around this surface. The holder 10, including the edge 16, is molded in one piece from plastic. This is cost-effective. It is understood that other materials, such as plastic, metal, carbon, or ceramic, can also be used to create a corresponding appearance. The edge 16 holds an inserted carrier 12 in its lateral position.

[0078] Small projections 18 are formed on the edge 16. The projections 18 are located in the upper region of the edge 16 and extend inward. This is illustrated in Figures 4B, 4F, and 4G. Corresponding projections 20 are formed on the carrier 12. In the present exemplary embodiment, two projections 20 are provided along each of the long sides of the edge 16 and one projection on the short side of the edge 16. This can be seen in Figure 3A. The projections 20 on the carrier 12 can be seen in Figures 3B, 3D, and 3E. It is understood that more or fewer projections can be used and their size can be varied in the circumferential direction.

[0079] One of the projections 20 is shown in detail in Figure 3E. It can be seen that the projections 20 taper slightly in cross-section. The shape and size of the projections 18 and 20 are designed such that they form a locking or clip mechanism. When the carrier 12 is inserted into the receptacle, as shown in Figure 3B, the projections 18 and 20 lock and hold the carrier 12 in its position so that it cannot move out of the receptacle 10 perpendicular to the plane of the receptacle 10. The taper facilitates locking. In the same way, the plate 27 is locked into the receptacle 28 with the ring 39. This is illustrated in Figures 5B and 5C.

[0080] A design element 14 is glued to the carrier 12. The carrier 12 and the design element thus form a module 36 that can be inserted together. Figure 3B illustrates how the module 36, consisting of the carrier 12 and the design element 14, is snapped into the receptacle 10. The module 36 is guided diagonally toward the edge 16 and pushed under one of the projections. The module 36 is then tilted downward and snapped into place with light pressure. It is easy to see that the module 36 requires significantly less material than the entire cover with the receptacle and the module 36.

[0081] The module 36 can be lifted again by grasping a recess 24 and 26 (Fig. 1) and removed from the holder 10. Lifting can be done with a fingernail or a tool. During removal, the module 36 is slightly bent in the middle area. This levers out the projections 18, 20 and releases the module 36.

[0082] The detachable arrangement allows for replacement with modules 36 with a different design or functionality. In the present embodiment, the carriers 12 are all identical. Design elements 14, such as printed foils, textiles, leather, and the like, are glued to the carriers 12. Depending on the requirements, different modules 36 with different design elements 14 can be inserted into the holder 10. The holder 10 always remains the same. This enables the use of a smartphone as an accessory, for example, in the fan or fashion sector.

[0083] Modules 36 can also be used that feature functionalities instead of design elements 14, which serve a purely aesthetic function. Such functionality could be, for example, a chip card applied to the carrier or a chip applied to the carrier 12. A module 36 with a chip is cost-effective. It can therefore be issued to selected individuals, similar to a key, at events, sporting and cultural events, or in venues, as an access element. It can open doors or serve as a payment system.

[0084] Figure 6 illustrates how functionality can be attached to the holder in addition to or as an alternative to flat design elements. In the present exemplary embodiment, the holder and, if applicable, the module 36 are provided with a bore 38 for this purpose. This can be clearly seen in Figure 1 and Figure 6A. A counterpart 40 is inserted into the bore 38 from the side facing the mobile radio terminal. The counterpart 40 is shown in detail again in Figure 6E. The counterpart 40 essentially consists of a threaded ring with an external thread and an adjoining flat edge 42 that extends radially outwards. The bore 38 is designed such that the counterpart 40 is completely countersunk and does not protrude from the flat surface of the holder 10 facing the mobile radio terminal.

[0085] An intermediate piece 44 is screwed onto the counterpart 40. For this purpose, the intermediate piece 44, shown in detail in Figure 6C, is provided with an internal thread in the area of ​​a tapered portion 46. The intermediate piece 44 protrudes on the side facing away from the counterpart and provides a fastening option for various functionalities. These functionalities can, for example, consist of three-dimensional, decorative attachments 48 connected to a snap fastener 50, shown in detail in Figure 6B. The snap fastener 50 can be pressed onto the intermediate piece 44 and released again, similar to a snap fastener.

[0086] Example 2: Fig.8-11 (magnetic fixing means)

[0087] Figures 8 to 11 show an alternative method for fixing a carrier 114 to the back of a mobile radio device. In this exemplary embodiment, the fixing means comprises one or more magnets and a receptacle 112. The magnets are glued to the back of the mobile radio device. For this purpose, an adhesive strip provided with a sacrificial film can be provided on the magnet. The sacrificial film is removed and glued to the surface of the mobile radio device. The gluing can be done using a stencil or the like to ensure that the magnets are applied in the desired position.

[0088] The magnets hold the receptacle 112. The receptacle has recesses 120, 122, 124, and 126 on the underside shown in Figure 11, i.e., on the side facing the mobile radio terminal. This can be seen in Figure 11. Flat metal strips are located in the recesses 122, 124, and 126. The position and dimensions of the recesses correspond to the position and dimensions of the magnets glued to the mobile radio terminal. When the receptacle 112 is brought into the area of ​​the mobile radio terminal equipped with the magnets, the receptacle 112 is magnetically attracted and positioned so that the magnets are precisely received in the recesses.

[0089] For mobile radio terminals with integrated magnets, metal areas 128—here circular—can also be provided in the area of ​​these magnets. These interact with the magnet integrated in the mobile radio terminal. A carrier 114, shown in Figures 9 and 10, can be inserted into the receptacle 112 as in the first exemplary embodiment. Depending on the design, it can be clipped in or—as in the illustrations—also held by magnets. For this purpose, the carrier 114 is provided with flat metal strips in recesses 130 on the side facing the receptacle. The metal strips 130 interact with magnets on the side of the receptacle 112 facing away from the mobile radio terminal.

[0090] It is understood that a magnetic effect can also be created if magnets and metal strips are swapped or if only magnets with the correct polarity are used.

[0091] Projecting adjustment profiles 118 interact with a matching recess 120 in the carrier 114, ensuring that the carrier 114 is always inserted in the correct position into a corresponding and matching receptacle 112.

[0092] 3. Embodiment (Fig.12-15)

[0093] In a third embodiment, the receptacle 212 is adhered to the back of the mobile radio terminal using an adhesive strip 216, as in the first embodiment. The receptacle 212 has openings into which housings 218 with magnets 220 are inserted. The carrier 214 shown in Figures 13 and 15 is provided with shallow recesses 222 in which metal strips are arranged. In this way, the carrier 214 is magnetically held in the receptacle 212.

[0094] The exemplary embodiments explained above serve to illustrate the invention claimed in the claims.
