Description

[0001] Cover device for a head-mounted visual output device, output device set and method

[0002] The present invention relates to a covering device for a head-mounted (i.e., designed to be worn on the head) visual output device. Furthermore, the invention relates to an output device set comprising a head-mounted visual output device and a covering device, as well as to a method for partially covering a head-mounted visual output device.

[0003] Head-mounted visual output devices, also known as “head-mounted displays,” exist in a wide variety of designs and for a variety of applications. Known output devices of this type comprise a functional module that is preferably worn on the forehead (i.e. intended to be worn on the forehead), which comprises a display device that is held in front of the eyes or at least one eye of a user when the output device is in use. Modified versions also position the functional modules on the side of the head and may only use monocular displays. In addition, such output devices comprise a headgear with which a user can fix the functional module, which is worn on the forehead, to their head. Such a headgear can, for example, comprise a band to be worn on the temple side and / or on the top of the head and / or at least one hoop or bracket to be worn accordingly.

[0004] In addition to the display device, the functional module to be worn on the forehead can in particular comprise at least partially a forehead cushion, a device control, at least one data storage device, at least one camera, at least one sensor, at least one operating element and / or at least one microphone.

[0005] At least one further functional module, which is to be worn, for example, at the back of the head, can be attached to the head holder and can in particular comprise at least one (preferably rechargeable) battery, at least one antenna, at least part of a device electronics, at least one data memory and / or at least one operating element.

[0006] Other versions of such output devices can also be connected to an external function module via a cable or wireless connection, which can be worn on a belt, for example, or formed by an external computer. There are also devices that are completely voice-controlled and therefore do not require keypad controls. In special versions, a main switch can be integrated into a hinge mechanism of the output device in such a way that it automatically turns the device on or off depending on the hinge position.

[0007] When used, such visual output devices can restrict a user’s field of vision to exclusively the artificial content displayed at a time (e.g. as pure video glasses or as a virtual reality headset) or simply enhance the user’s natural view of their surroundings with additional information (e.g. as augmented reality glasses). They can be used both in the entertainment sector and in the professional field, for example to simulate, in particular practice, certain activities or to perform certain actions with artificial support. By being attached to the head, the wearer retains a maximum of freedom of movement and can, in particular, use both hands for actions, for example to influence the content displayed and / or to carry out complex work processes depending on the information displayed.

[0008] JP 2018-137626 A shows an image generation device comprising a mount that is part of a cap and has an extended portion. Furthermore, the image generation device comprises an image display device attached to the extended portion. The figures also show a cap body surrounded in its lower region by the annular body portion. This device thus allows the attachment of a head-mounted display to a helmet.

[0009] US 2020 / 0033601 A1 describes a head-mounted display system. The user of the system preferably wears a fabric cap to which several haptic feedback actuators are attached.

[0010] DE 20 2021 003 714 Ul describes a head mount for implementing a head-mounted display. It describes a foldable frame that can be placed on the user's head and can be shaped as desired.

[0011] The object of the present invention is to provide a technology that allows head-mounted visual output devices to be adapted to requirements dependent on their respective area of ​​application, thus expanding the range of possible uses for these output devices in a simple and convenient manner. This object is achieved by a covering device according to claim 1, by an output device set according to claim 6, and by a method according to claim 9. Advantageous embodiments are disclosed in the subclaims, the description, and the figures.

[0012] A covering device according to the invention is an additional component for a visual output device to be worn on the head, which comprises a functional module to be worn on the front with a display device and - for fixing it to the head of a user - a head holder.

[0013] The covering device comprises a bag which is designed or suitable to be pulled over the headgear (in the form intended for use) as well as over a section of the functional module, referred to below as the "module section", which is spaced from the display device. The bag explicitly does not have a supporting function but serves to protect or encapsulate the headgear and the module section. This means that the bag can be quickly removed or replaced after use, so that all other components of the dispensing device can still be used, for example if the user changes.

[0014] In addition, the covering device comprises a holding frame designed to clamp an edge strip of the bag (i.e., a strip-like area on the edge of the bag surrounding a bag opening) to the module section spaced apart from the display device, thus closing the bag with the functional module while leaving the display device free. The holding frame is removable after the clamping area has been subsequently opened; it can therefore be removed from the functional module, in particular from the module section, without damage, which then terminates the clamping and allows the bag to be removed.

[0015] The support frame preferably has a variable shape. Such a frame can be particularly easily attached to and removed from the functional module to be supported at the front. The support frame can, in particular, be detachable, i.e., can be selectively (repeatedly) opened and closed and then, only in a closed state, form a frame shape, i.e., enclose a frame interior.

[0016] An output device set according to the invention comprises a head-mounted visual output device having a head mount and a functional module comprising a display device, which is worn on the forehead. Furthermore, the output device set comprises a covering device according to one embodiment of the present invention.

[0017] The covering device is designed to fit the dispensing device, i.e., its bag is suitable for receiving the head holder and (simultaneously) at least one module section of the functional module spaced apart from the display device, and its holding frame is designed to clamp an edge strip of the bag to the module section spaced apart from the display device, thus closing the bag with the functional module while leaving the display device free. To complete the clamping process, the holding frame can be removed from the functional module, in particular the module section, without causing damage.

[0018] In particular, the mounting frame thus has a shape that is at least partially adapted to the output device. It can, at least in part, replicate an imprint of the module section spaced from the display device, into which the module can be inserted (preferably with a precise fit) when clamped.

[0019] A method according to the invention is used for partially enveloping a visual output device to be worn on the head, which comprises a functional module to be worn on the front, with a display device, and a headrest. The method comprises pulling the bag with a covering device according to an embodiment of the present invention over the headrest and also over a module section of the functional module to be worn on the front, which module section is spaced apart from the display device. By means of the holding frame of the covering device, according to the method an edge strip of the bag is then clamped to the module section spaced apart from the display device, and the bag is thus closed by the functional module (arranged in the bag with the module section), leaving the display device free.To finish the housing of the output device, the support frame of the function module is preferably removable without damage, whereby the connection can be finished.

[0020] The support frame and bag are preferably separate (in particular, separate or separable) components. This allows, in particular, the bag to be interchangeable while the support frame can be used multiple times.

[0021] The present invention thus allows a head-worn output device to be partially covered by the covering device, while still allowing a user to see the display device and thus the visual information output by the output device, thus allowing the output device to continue to be used (preferably without restrictions). The removable support frame allows for simple and convenient repeated use of the output device, either with or without the covering device.

[0022] In this way, a user can quickly and easily make the dispensing device suitable for use in a particular environmental situation. In particular, a suitable choice of bag material can prevent moisture or particles (e.g. dust, dirt) from penetrating the dispensing device from the user's head or from the environment in which the dispensing device is used, which could otherwise damage the dispensing device. Conversely, in clean rooms, for example, it can be achieved that applicable regulatory guidelines can be adhered to even when the dispensing device is in use, by preventing particles that may be present on the dispensing device from contaminating the clean room.Since the functional module, which is worn on the front, closes the bag, the dispensing device can also be easily put on and taken off again even when partially wrapped in this way, while maintaining the protective effect.

[0023] The clamping is preferably carried out directly, i.e. in contact of the bag with the module section and the support frame, thus without any additional element arranged in between.

[0024] According to advantageous embodiments of the present invention, the mounting frame is configured to keep one or more additional functional elements of the dispensing device (such as, in particular, at least one sensor and / or at least one camera) at least partially free from the bag, i.e., outside the bag, when clamped on. This allows these functional elements to remain usable (preferably without restriction) even when the dispensing device is partially covered by the covering device.

[0025] Alternatively or additionally, the support frame can have at least one frame region with at least one opening that connects a frame interior surrounded by the support frame with an external environment of the frame. In this way, a housing opening, if present in the dispensing device, can be covered with the bag but kept accessible through the support frame, so that a function of the housing opening (e.g., for ventilation or as microphone or sensor access) is retained.

[0026] According to advantageous embodiments, the holding frame forms at least one receiving recess for the functional module to be supported on the front, into which recess the functional module is to be inserted for clamping the edge strip of the bag. Such a receiving recess can advantageously define at least one position in which the functional module to be supported on the front is to be arranged when clamped relative to the holding frame. This makes it particularly easy to put on the holding frame and achieves a solid, non-slip clamping with an advantageously tight seal on the functional module to be arranged on the front. In particular, in corresponding embodiments this can make it easier to hold at least one further functional element outside the bag during clamping, as mentioned above, and / or to position at least one opening, if present, in the holding frame suitably on a housing opening in the functional module to be supported on the front.

[0027] The bag is preferably made at least partially from a flexible, in particular fabric-, film- and / or paper-like material, for example from a woven fabric, a nonwoven (which can be formed, for example, from polyethylene filaments) and / or a film.

[0028] According to advantageous embodiments of the present invention, the bag is at least partially waterproof and / or impermeable to inorganic dust particles and / or organic structures, for example, fungal spores, bacteria, or viruses. The material thickness of the bag is preferably (at least in some areas) at most 1 mm or at most 0.5 mm.

[0029] Similarly, a clamped connection between the bag and the functional module is preferably waterproof and / or impermeable to inorganic dust particles and / or organic structures, such as fungal spores, bacteria, or viruses. Moisture or the respective particles and / or structures cannot then penetrate the connection into or out of the bag.

[0030] According to advantageous embodiments, the bag is suitable for accommodating, together with the head support and the module section of the functional module to be worn at the front, which is spaced apart from the display device, at least one further functional module that may be additionally included in the output device, for example a functional module to be worn at the back of the head.

[0031] The support frame can preferably be made at least partially of (particularly fiber-reinforced) ceramic, plastic, carbon, and / or metal. Such materials are particularly durable and easy to clean. The support frame can, for example, comprise at least one component manufactured by means of 3D printing, injection molding, and / or compression molding.

[0032] According to advantageous embodiments, the support frame has at least one dimensionally stable (particularly rigid) region. This enables particularly simple operation, and the dimensional stability also prevents the support frame from accidentally slipping off the output device.

[0033] A surface of the mounting frame can comprise at least one strip which is to be directed towards the output device when clamped on, the width of which strip (as its smaller dimension) is at least 1 cm, at least 2 cm or even at least 3 cm. The strip can be designed such that, in the direction of its width when clamped on, it runs parallel to an intended viewing direction or extends at an angle, in particular perpendicular to the intended viewing direction; the intended viewing direction is to be understood as a direction in which a user of the output device is intended to look at its display device.

[0034] Such support frames enable a particularly durable, load-resistant and tight clamping of the edge strip of the bag to the functional module to be carried at the front, because the bag can be pressed against the functional module along the width of the strip.

[0035] According to advantageous embodiments, the support frame comprises two separable (preferably at least partially rigid) frame elements. In order to close the support frame (and thus to form the frame shape), the frame elements can be detachably connected to one another by at least one further (in particular separate) element of the support frame. Such a further element can, for example, comprise an adjustable strap and / or consist at least partially of an elastic material (e.g. silicone and / or rubber); in particular, it can be designed as a ring. At least one of the frame elements can have at least one fixing element which is designed to fix the further element to the corresponding frame element and thus enable the connection of the frame elements.Alternatively or additionally, at least one of the frame elements can have an integrated locking device, for example a snap-in and / or locking device, by means of which the frame elements are to be connected. When clamped together, the interconnected frame elements can touch one another or be spaced apart from one another.

[0036] According to another embodiment, the support frame can comprise two (preferably at least partially rigid) wings which are pivotally connected to one another in a joint and which, in order to form the frame, are each detachably connected to one another at an end opposite the joint by at least one further (in particular separate) element of the support frame and / or by a closure device integrated into at least one of the wings. Analogous to the above, the at least one further element in such embodiments can comprise an adjustable strap and / or consist at least partially of an elastic material (e.g. silicone and / or rubber); in particular, it can be designed as a ring.At least one of the wings can have, at its end opposite the joint, at least one fixing element designed to fix the other element to the corresponding wing and thus enable the connection of the wings. Said integrated locking device, if present, can comprise, for example, a snap-in and / or locking device. When clamped together, the interconnected wings can touch one another or be spaced apart from one another.

[0037] In particular, in these exemplary embodiments, at least one of the frame elements or at least one of the wings can form a receiving recess for the functional module to be supported on the front side, as described above.

[0038] It is understood that alternative designs of the support frame are also possible. In particular, the support frame can be made of one or more parts.

[0039] According to advantageous embodiments of the present invention, the mounting frame has a three-dimensional profile, i.e., a tactilely detectable structure, on its surface facing the module section spaced apart from the display device during clamping. Such a profile can, for example, comprise one or more knobs, grooves, rails, and / or bulges.

[0040] In particular, such a profile can be configured to press the edge strip of the bag against the aforementioned module section with a diversely distributed force during clamping. This can reduce the tendency of the bag to slip relative to the support frame, thus ensuring a particularly durable fixation of the bag to the dispensing device.

[0041] Alternatively or additionally, the support frame may comprise one or more stabilizing structures configured to interact with a counterstructure on the functional module to be supported at the front, thus stabilizing the fixation. Such interaction may, in particular, comprise engagement of the stabilizing structure with the counterstructure and / or of the counterstructure with the stabilizing structure.

[0042] According to advantageous embodiments of a dispensing device set according to the invention, the edge strip of the bag can be clamped onto the functional module to be positioned on the front side in such a way that the bag covers at least one, preferably every, area of ​​the dispensing device that is unsuitable for wet cleaning. Accordingly, in a method according to the invention, the clamping is preferably carried out in such a way that the bag covers at least one, preferably every, area of ​​the dispensing device that is unsuitable for wet cleaning. In this way, depending on the material and area of ​​application, the bag can prevent moisture from an environment from damaging the dispensing device and / or particles or structures that cannot be removed from such areas because wet cleaning is not possible there from getting into an environment of the dispensing device set in use, for example a clean room, and thus contaminating this environment.

[0043] It is also important for certain applications that parts of the dispenser located inside the bag during use of the dispenser set can be cleaned frequently as needed, sometimes using aggressive cleaning agents and chemicals. The resulting waste is contained within the bag and cannot contaminate the environment.

[0044] In particular, a housing element of the functional module to be supported on the front side can have at least one housing opening in the module section spaced apart from the display device. In such cases, the holding frame preferably has at least one frame region with at least one opening (as mentioned above), which is then to be arranged or - during the movement - is arranged at least partially on the at least one housing opening covered by a section of the bag wall when the edge strip of the bag is clamped on. In this way, a function of the housing opening, for example for ventilating a functional unit of the dispensing device or as sensor or microphone access, can be retained even when the dispensing device is partially covered by the covering device.

[0045] Preferred embodiments of the invention are explained in more detail below with reference to the drawings. It is understood that individual elements and components can also be combined differently than shown. Reference numerals for corresponding elements are used throughout the figures and may not be described again for each figure.

[0046] They show schematically:

[0052] Fig. 4c: the output device set according to Figs. 4a and 4b during its intended use on the head of a user.

[0053] Figs. 1a and 1b show an example of a visual output device 20 to be worn on the head. The output device 20 comprises a functional module 21 to be worn on the forehead with a display device 21 A and a forehead cushion 21 s, a further functional module 22 to be worn at the back of the head and a head support 23 , to which in the present case a band 23 to be worn on the temple side s and a band to be worn on top of the head 23 O belong .

[0054] As can be seen in Fig. 1b, the band 23 to be worn on the temporal side is s by means of an adjustment wheel 23 attached to the further functional module 22 E adjustable to a respective head size and the user looks through a designated viewing area S at the display device 21 A . The band to be worn on the top of the head 23 O forms a loop that is adjustable to fit any head size.

[0055] The functional module 21 to be supported on the front side can comprise at least part of a device electronics (in particular at least part of a device control, at least one data memory, at least one camera, at least one sensor, at least one operating element and / or at least one microphone). It is at least partially enclosed by a housing element 21 G enclosed .

[0056] The housing element 21 G has housing openings 21 L which can, for example, serve to ventilate the components contained. Especially in the area of ​​the housing openings 21 LTherefore, wet cleaning of the output device would jeopardize its functionality; for this reason, particles that cannot be removed, in particular organic structures (such as fungal spores, bacteria or viruses) or inorganic particles can conventionally enter the application environment from the output device (in particular through the housing openings) and possibly contaminate it. Conversely, when using the output device 20, for example, in humid or dusty environments, the functional module 21 can enter the application environment through the housing openings 21. L be damaged through .

[0057] The same applies to the further functional module 22, which can comprise, for example, at least one (preferably rechargeable) battery, at least one antenna, at least part of a device electronics, at least one data memory and / or at least one operating element (not visible in the figures) and which usually has module sections which are not waterproof, in particular which are opposed to wet cleaning.

[0058] A covering device 10 according to the invention makes it possible to counteract these disadvantages. It can be designed in particular according to the exemplary embodiment shown in Figs. 2 to 4c. In Fig. 2, the covering device 10 is shown alone and in an exploded view. It comprises a bag 11 which - as can be seen in Figs. 4a to 4c - is designed (suitable) to be placed over the further functional module 22 to be worn at the back of the head, the head support 23 and a display device 21 A spaced module section 21 B of the functional module 21 to be supported at the front.

[0059] The bag 11 is preferably made at least partially of a flexible, particularly fabric-, film-, and / or paper-like material. In particular, the bag can be impermeable to organic structures such as fungal spores, bacteria, and / or viruses, which may be present especially in areas of the dispensing device that cannot be cleaned with wet cleaning.

[0060] As can also be seen in Fig. 2, the bag 11 has a bag opening Ö, which is formed by an edge 11 R of the bag and is thus defined. An edge strip 11s, i.e. a strip-like area at the edge 11R, is in the area defined by the display device 21 A spaced module section 21 B of the functional module 21 to be supported on the front, whereby the bag 11 is closed; this can be seen in Figs. 4a - 4c.

[0061] A holding frame 12, which is also encompassed by the covering device 10, is used for clamping and is designed here as a detachable frame with two separate, each dimensionally stable (rigid) frame elements 12a, 12b and comprises two further elements 12c, 12d. Fig. 3 shows the frame separately and in a different perspective than Fig. 2. In Figs. 2 and 3, the frame is each shown in an exploded view, which corresponds to a released state. In particular, the holding frame 12, when it has the edge strip 11 s at module section 21 B clamped, by establishing this released state of the functional module 21 to be supported on the front side, in particular its module section 21 B (preferably without damage) and the bag 11 can then be removed from the dispensing device 20.

[0062] The further elements 12c, 12d each serve to connect the two frame elements 12a, 12b to each other (at a respective end of the frame elements). In the illustrated embodiment, they are designed as oval rings, which are preferably elastic (for example, at least partially made of rubber and / or silicone). To connect the frame elements 12a, 12b, they are formed into fixing elements 12a, 12b formed at the end of the frame elements 12a, 12b. A , 12b Ä hung and thus fixed to the frame elements.

[0063] In this case, the frame element 12a forms a receiving recess for the functional module 21 to be supported on the front side. This defines a position suitable for clamping the support frame 12 relative to the functional module 21 to be supported on the front side, which position can then be easily implemented by the user.

[0064] As shown in Fig. 2, the frame element 12a has a surface which forms a surface when clamping the edge strip ll s of the bag 11 to the module section 21 B facing surface strip Si of strip width Bi. The frame element 12b has a surface which faces the module section 21 B surface strips S to be turned when clamping B the strip width B B In the direction of its strip width Bi, the strip Si runs parallel to an intended viewing direction in the illustrated embodiment (see Fig. 4c), and the strip S2 runs perpendicular to the intended viewing direction in the direction of its strip width B2. Preferably, at least one of the strip widths is at least 1 cm, at least 2 cm, or even at least 3 cm. As a result, the mounting frame can ensure a particularly durable and tight clamping of the edge strip 11. Rof the bag 11 on the functional module 21 to be supported on the front side. In the illustrated embodiment, the strip widths Bi and B2 are different from one another; in particular, in this case, Bi > B2 applies.

[0065] As can be seen in particular from Fig. 3, the support frame 12 has on its frame elements 12a, 12b two pin-shaped stabilizing structures 12a s , 12b s which are designed to interact with a respective counter-structure on the output device (not visible in the figures), namely in this case to engage in respective recesses or openings in a surface of the functional module 21. The stabilizing structures serve to ensure a particularly stable, in particular slip-proof, fixation of the holding frame 12 to the functional module 21 to be supported on the front side when clamped on.

[0066] Both frame elements 12a, 12b also have, in the present case, on their respective sides, the side of the display device 21 A spaced module section 21 B facing surface has a three-dimensional profile; due to the perspective, this is only visible in Fig. 2 for the frame element 12b, Figs. 3 and 4b also show the profile on the frame element 12a. The three-dimensional profile in this case comprises a plurality of profile elements 12a P , 12b P , which in the illustrated embodiment are each designed as knobs. The profile serves to generate uneven forces at the various points during clamping, which reduces the slippage of the bag 11 relative to the support frame 12.

[0067] Figs. 4a to 4c show various views of an exemplary embodiment of a dispensing device set 100 according to the invention, which comprises a dispensing device 20 and a covering device 10 according to the invention, as shown in Figs. 1a, 1b and 2, respectively; Fig. 4c shows the dispensing device set 100 in use. For a better understanding of the arrangement, hidden components in Figs. 4a to 4c are shown with dashed lines.

[0068] In Fig. 4a, 4b it is illustrated how the support frame 12 when clamping the edge strip ll s of the bag 11 at the module section 2 1 spaced from the display device B of the functional module 21 to be supported on the front side. In particular, it can be seen that the frame elements 12a, 12b of the support frame 12 have a housing element 21 Ghave an adapted shape, even partially replicate an impression of the functional module 21, into which it is precisely inserted when clamped.

[0069] In this case, two openings 12a formed in the support frame 12 L on each of the housing openings 21 covered by the bag 11 L arranged. This allows the function of the housing openings 21 L (e.g. as a fan opening) are retained, and the housing openings 21 L can nevertheless be covered by the bag and thus secured.

[0070] The openings 12b arranged in the frame element 12b L can also be used analogously on housing openings in the housing element 21 that are not visible in the figures G to be arranged or to be arranged.

[0071] In Fig. 4c it can be seen that the bag 11 with its edge strip ll s by means of the support frame 12 on the display device 21A spaced module section 21 B of the functional module 21 to be worn on the front side is clamped and thus the bag 11 is closed with the functional module 21 to be worn on the front side. The display device remains free, in particular the intended viewing space S between the eyes of the user and the display device 21 A kept free from the coating device 10 .

[0072] Thus partially wrapped, the user can conveniently remove the dispensing device set 100 from his head, for example for interruptions in use, in particular during work breaks, and put it back on later, without losing the protective effect achieved by the covering device 10.

[0073] It is understood that the user may also wear protective clothing not shown in Fig. 4c, in particular between his head and the dispensing device 20 attached together with the covering device 10.
