Description

[0001] The present invention is based on a covering device for a visual output device that needs to be worn on the head (i.e., designed to be worn on the head). In addition, the present invention relates to an output device kit including a visual output device that needs to be worn on the head and a covering device, as well as a method for partially covering a visual output device that needs to be worn on the head.

[0002] Visual output devices that need to be worn on the head, also known in English as "Head-Mounted Displays", exist in various designs and for various fields of application. Such known output devices include a functional module that preferably needs to be worn on the forehead side (i.e., is determined to be worn on the forehead side), the functional module including a display device, which is kept in front of the user's eyes or at least one eye when the output device is used. The modified design also positions the functional module on the side of the head and only uses a monocular display when necessary. In addition, such an output device includes a head holder, through which the user can fix the functional module that needs to be worn on the forehead side on his head. Such a head holder can, for example, include a band that needs to be worn on the temple side and / or a band that needs to be worn on the top of the head and / or at least one ring or clamp that needs to be worn accordingly.

[0003] In addition to the display device, the functional modules to be worn on the forehead can in particular at least partially include a forehead pad, a device control device, 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.

[0004] At least one other functional module, which is to be worn, for example, on the back of the head, can be fixed to the head holder and can include, in particular, at least one (preferably rechargeable) battery, at least one antenna, at least part of the device electronics, at least one data storage device and / or at least one operating element.

[0005] Other designs of such output devices can also be connected via a cable or via a wireless connection to an external functional module, which can be worn on a belt or formed by an external computer, for example. There are also devices that are completely voice-controlled and can therefore do without key operating elements. In a special design, the main switch can be integrated in the hinge mechanism of the output device so that it automatically opens or closes the device depending on the hinge position.

[0006] Such visual output devices can be used to restrict the user's field of view to the respectively displayed artificial content (e.g. as pure video glasses or as virtual reality headsets) or to simply expand the user's natural view of his environment with additional information (e.g. as augmented reality glasses). In this case, the output device can be used both in the entertainment sector and in the professional field, for example for simulating, in particular practicing, specific tasks or for performing certain operations with human assistance. By fastening to the head, the wearer of the output device retains a maximum degree of freedom of movement and can use both hands in particular for actions, for example to influence the respectively displayed content and / or to execute complex workflows in conjunction with the respectively displayed information.

[0007] JP 2018-137626 A shows an imaging device comprising a holder which is part of a cover and has an extended section. In addition, the imaging device comprises an image display device which is mounted on the extended section. The cover body can also be seen in the drawings, which is surrounded by an annular main body part in its lower region. Thus, the device enables the head-mounted display to be mounted on a helmet.

[0008] US2020 / 0033601 A1 describes a head mounted display system. The user of the system preferably wears a fabric cap on which a plurality of tactile feedback actuators are mounted.

[0009] A head holder for realizing a head-mounted display is known from DE 20 2021 003 714 U1. A foldable support is described which can be arranged on the head of a user and can be shaped as desired.

[0010] The technical problem to be solved by the present invention is to provide a technology that allows visual output devices that need to be worn on the head to be adjusted according to their requirements related to the corresponding scope of use and thereby increase the range of possible uses for such output devices in a simple and convenient manner.

[0011] This object is achieved by a covering device according to claim 1, by a dispensing device kit according to claim 6 and by a method according to claim 9. Advantageous embodiments are disclosed in the dependent claims, the description and the drawings.

[0012] The covering device according to the present invention is an additional component for a visual output device that needs to be worn on the head, wherein the visual output device includes a functional module that needs to be worn on the forehead side and a head holder for fixing the functional module on the user's head, wherein the functional module has a display device.

[0013] The covering device comprises a pocket which is arranged or suitable for covering both the head holder (in the shape in which the head holder is arranged for use) and also a section of the functional module, referred to below as the "module section", which is spaced apart from the display device. The pocket here explicitly does not have a load-bearing function, but serves to protect or enclose the head holder and the module section. The pocket can thus be quickly removed or replaced after use, so that, for example, all other components of the output device can still be used when the user replaces it.

[0014] Furthermore, the covering device comprises a holding frame, which is provided for clamping the edge strip of the pocket (i.e. the strip-shaped area at the edge of the pocket surrounding the pocket opening) on ​​the module section spaced apart from the display device and thus closing the pocket with the functional module while exposing the display device. The holding frame can be removed later after the clamping area has been opened, so that it can be removed from the functional module, in particular the module section, without damage, which ends the clamping and allows the pocket to be removed.

[0015] The holding frame preferably has a variable shape. Such a frame can be particularly easily mounted on the functional module to be worn on the forehead and removed again. The holding frame can be particularly detachably, i.e. selectively (repeatedly) opened and closed and thus only forms a frame shape in the closed state, i.e. surrounds the frame interior space.

[0016] The output device kit according to the present invention comprises a visual output device to be worn on the head, the output device having a head holder and a functional module including a display device to be worn on the forehead side. In addition, the output device kit comprises a covering device according to an embodiment of the present invention.

[0017] The covering device is hereby coupled to the output device, i.e. the pocket of the covering device is suitable for accommodating the head holder and (at the same time) at least one module section of the functional module spaced apart from the display device, and its holding frame is provided for clamping the edge strip of the pocket on the module section spaced apart from the display device and thus closing the pocket with the functional module while the display device is exposed. To terminate the clamping, the holding frame can be removed non-destructively from the functional module, in particular the module section.

[0018] The holding frame thus has in particular a shape at least partially adapted to the output device. Here, the holding frame can at least regionally replicate the footprint of the module section spaced apart from the display device, into which it can be inserted when clamped (preferably with an exact fit).

[0019] The method according to the present invention is used to partially cover a visual output device that needs to be worn on the head, the visual output device includes a functional module that needs to be worn on the forehead side and a head holder, and the functional module has a display device. The method includes covering the pocket of the covering device according to an embodiment of the present invention on the head holder and also covering the module section of the functional module that needs to be worn on the forehead side that is spaced apart from the display device. According to the method, the edge strip of the pocket is clamped on the module section that is spaced apart from the display device by means of the holding frame of the covering device, and thereby the pocket is closed by the functional module (arranged in the pocket with the module section) while the display device is exposed. In order to end the closure of the output device, the holding frame can be preferably removed from the functional module without damage, thereby ending the clamping.

[0020] The holding frame and the pocket are preferably independent (especially separated or separable) parts respectively. This especially realizes the replaceability of the pocket, while the holding frame can be used multiple times.

[0021] The present invention thus enables the output device to be partially covered by the covering device, while at the same time allowing the user to see the display device and thus the visual information output by the output device, i.e., to continue to use the output device (preferably without restriction). The removable holding frame hereby allows the output device to be reused in a simple and convenient manner, optionally with or without the covering device.

[0022] As a result, the user can quickly and easily adapt the output device to the corresponding environmental conditions. In particular, when the pocket material is appropriately selected, it is possible to prevent moisture or particles (such as dust, dirt) from penetrating into the output device, which may come from the user's head or the environment in which the output device is used and may otherwise damage the output device. In addition, it is possible, for example, to comply with the regulations applicable there when using the output device in a clean room, i.e. in such a way that particles that may be present on the output device are prevented from contaminating the corresponding clean room. Since the functional module to be worn on the forehead closes the pocket, the output device can be easily installed and removed again in this partially covered state while maintaining its protective effect.

[0023] The clamping preferably takes place directly in each case, ie in contact of the pocket with the module section and the holding frame, ie in each case without further elements being arranged in between.

[0024] According to an advantageous embodiment of the invention, the holding frame is designed to also hold one or more possibly present further functional elements of the output device (such as in particular at least one sensor and / or at least one camera) at least partially out of the pocket, i.e. outside the pocket, during clamping. As a result, these functional elements remain accessible (preferably unrestricted) even when the output device is partially enveloped by the envelope.

[0025] As an alternative or in addition, the holding frame can have at least one frame region with at least one opening, which connects the frame interior space enclosed by the holding frame with the environment outside the frame. In this way, any housing openings that may be present in the output device can be covered by the pocket, but still remain accessible through the holding frame, thereby maintaining the functionality of the housing opening (e.g. for ventilation or as microphone or sensor inlet).

[0026] According to an advantageous embodiment, the holding frame forms at least one receiving groove for the functional module to be worn on the forehead side, into which the functional module can be inserted to clamp the edge strip of the pocket. Such a receiving groove can advantageously determine at least one position in which the functional module to be worn on the forehead side should be arranged relative to the holding frame during the clamping process. As a result, the holding frame can be arranged particularly easily and a fixed, non-slip clamping and an advantageously sealed closure on the functional module to be arranged on the forehead side can be achieved. Therefore, in particular in a corresponding embodiment, it can be simplified that at least one other functional element is kept outside the pocket during the clamping process as described above, and / or at least one opening that may be present in the holding frame is appropriately positioned on the housing opening in the functional module to be worn on the forehead side.

[0027] The pocket is preferably made at least partially from a flexible material, in particular a textile, film and / or paper material, for example a woven fabric, a nonwoven (which may be formed, for example, from polyethylene monofilaments) and / or a film.

[0028] According to an advantageous embodiment of the invention, the pocket is at least partially waterproof and / or impermeable to inorganic dust particles and / or organic structures, such as fungal spores, bacteria or viruses. The material thickness of the pocket is preferably (at least regionally) at most 1 mm or at most 0.5 mm.

[0029] Similarly, the connection between the pocket and the functional module produced by clamping is preferably waterproof and / or impermeable to inorganic dust particles and / or organic structures, such as fungal spores, bacteria or viruses. Thus, moisture or corresponding particles and / or structures cannot enter or flow out of the pocket through the connection.

[0030] According to an advantageous embodiment, the pocket is suitable for accommodating, together with the head holder and the module section of the functional module to be worn on the forehead side, which is spaced apart from the display device, at least one other functional module that the output device may additionally include, for example a functional module to be worn on the back of the head.

[0031] The holding frame can preferably be at least partially composed of (especially fiber-reinforced) ceramic, plastic, carbon and / or metal. These materials are particularly durable and easy to clean. For example, the holding frame can include at least one component manufactured by 3D printing, injection molding and / or stamping.

[0032] According to an advantageous embodiment, the holding frame has at least one dimensionally stable, in particular rigid, region. This allows particularly simple handling, while the dimensionally stable shape also prevents the holding frame from undesirably sliding off the output device.

[0033] The surface of the holding frame can include at least one strip facing the output device during clamping, whose strip width (as its smaller dimension) is at least 1 cm, 2 cm or even 3 cm. The strip can be designed in such a way that during clamping it extends in the direction of its strip width parallel to a predetermined viewing direction or obliquely, in particular perpendicularly, to the predetermined viewing direction; the predetermined viewing direction is to be understood as the direction in which a user of the output device is intended to view its display device.

[0034] Such a holding frame allows a particularly durable, load-resistant and tight clamping of the edge strip of the pocket on the functional module to be worn on the forehead side, since the pocket can be pressed onto the functional module along the strip width.

[0035] According to an advantageous embodiment, the holding frame comprises two (preferably at least partially rigid) frame elements that can be separated from each other. The frame elements can be detachably connected to each other via at least one other (especially independent) element of the holding frame in order to close the holding frame (thereby forming a frame shape). For example, such other elements can be adjustable straps and / or at least partially consist of elastic material (such as silicone and / or rubber), and can in particular be designed as rings. At least one frame element can have at least one fixing element, which is arranged to fix the other element to the corresponding frame element, so as to achieve the connection of the frame elements. As an alternative or in addition, at least one frame element can have an integrated locking device, such as a latching and / or locking device, by which the frame elements can be connected. When clamped, the frame elements connected to each other can be in contact with each other or spaced apart from each other.

[0036] According to another embodiment, the holding frame can include two (preferably at least partially rigid) wings that can be connected to each other in a hinge so as to pivot relative to each other, and the wings need to be detachably connected to each other at the ends opposite to the hinge direction by at least one other (especially independent) element of the holding frame and / or by a locking device integrated in at least one wing to form a frame. Similar to the above, in these embodiments, at least one other element can include an adjustable strap and / or at least partially composed of elastic material (such as silicone and / or rubber), and can be designed as a ring in particular. At least one wing can have at least one fixing element at its end opposite to the hinge direction, and the fixing element is arranged to fix the other element to the corresponding wing, so as to achieve the connection of the wing. The integrated locking device (if any) can, for example, include a latch and / or a locking device. When clamped, the interconnected wings can contact each other or be spaced apart from each other.

[0037] In particular, in these exemplary embodiments, at least one frame element or at least one wing can form a receiving recess for a functional module to be worn on the forehead side as described above.

[0038] It goes without saying that alternative other designs of the holding frame are also possible. The holding frame can in particular be one-piece or multi-piece.

[0039] According to an advantageous embodiment of the invention, the holding frame has a three-dimensional profile, ie a tactilely perceptible structure, on its surface facing the module section spaced apart from the display device during the clamping process. For example, such a profile may include one or more knots, grooves, rails and / or projections.

[0040] Such a profile can be provided in particular for pressing the edge strip of the bag onto the module section with a dispersed force during clamping. The sliding property of the bag relative to the holding frame can thus be reduced, thereby achieving a particularly durable fixation of the bag on the dispensing device.

[0041] As an alternative or in addition, the holding frame may include one or more stabilizing structures, which are arranged to interact with the mating structures on the functional module to be worn on the forehead side, so as to stabilize the fixation. This interaction may in particular include the engagement of the stabilizing structure in the mating structure and / or the engagement of the mating structure in the stabilizing structure.

[0042] According to an advantageous embodiment of the output device kit according to the invention, the edge strip of the pocket can be clamped onto the functional module to be positioned on the forehead side in such a way that the pocket covers at least one, preferably each, area of ​​the output device that is not suitable for wet cleaning. Accordingly, in the method according to the invention, the clamping is preferably performed in such a way that the pocket covers at least one, preferably each, area of ​​the output device that is not suitable for wet cleaning. In this way, depending on the material and the field of application, the pocket can prevent moisture from the environment from damaging the output device and / or prevent particles or structures that cannot be removed from these areas because wet cleaning is not possible there from entering the environment of the output device used, for example a clean room, and thereby contaminating said environment.

[0043] It is also important for specific applications that the dispensing device part that is inside the pocket when the dispensing device is used can also be cleaned frequently when necessary using partially corrosive cleaning agents and chemicals. The secretions formed here are stored in the pocket and do not pollute the environment.

[0044] The housing element of the functional module to be worn on the forehead side can have at least one housing opening in the module section spaced apart from the display device. In these cases, the holding frame preferably has at least one frame region with at least one opening (as described above), and then when the edge strip of the pocket is clamped, the at least one opening needs to be at least partially arranged on at least one housing opening covered by a section of the pocket wall, or in the method, the at least one opening is at least partially arranged on at least one housing opening covered by a section of the pocket wall. As a result, the function of the housing opening, for example, for ventilation of a functional unit of the output device or as an inlet for a sensor or microphone, remains unchanged even when the output device is partially enclosed by the enclosing device.

[0045] The preferred embodiments of the present invention are described in more detail below with reference to the accompanying drawings. It goes without saying that the individual elements and components can also be combined differently from those shown. The reference numerals for the corresponding elements are common in the accompanying drawings and may not be described again for each drawing.

[0053] Figure 4c :Show the basis Figure 4a and Figure 4b The output device kit of FIG. 1 is shown in FIG. 1 when it is used as intended on the head of a user.

[0054] Figure 1a and 1b An example of a visual output device 20 that needs to be worn on the head is shown. In this example, the output device 20 includes a functional module 21 that needs to be worn on the forehead side, other functional modules 22 that need to be worn on the back of the head, and a head holder 23. The functional module that needs to be worn on the forehead side has a display device 21. A And forehead pad 21 S In this example, the head holder 23 includes a band 23 that needs to be worn on the temple side. S and a belt that needs to be worn on the top of the head 23 O .

[0055] from Figure 1b As can be seen from the figure, the belt 23 that needs to be worn on the temple side S The adjustment wheel 23 fixed to the other functional module 22 can be E Adjusted to the corresponding head size, the user observes the display device 21 through the set observation space S A . Requires to be worn on top of the head 23 O A loop is formed which is adjustable in order to fit a corresponding head size.

[0056] The functional module 21 to be worn on the forehead may include at least a portion of the device electronics (in particular at least a portion of the device control device, 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). The functional module is at least partially enclosed by the housing element 21. G surrounded.

[0057] Housing element 21G Having a housing opening 21 L , the housing opening can be used to ventilate the contained components. Therefore, in particular in the housing opening 21 L wet cleaning of the output device would impair its functionality; particles that cannot be removed thereby, in particular organic structures (such as fungal spores, bacteria or viruses) or inorganic particles, therefore usually enter the application environment from the output device (in particular through the housing opening) and can contaminate it. Conversely, when the output device 20 is used, for example, in a humid or dusty environment, it is possible that particles can pass through the housing opening 21. L Damage function module 21.

[0058] This applies accordingly to other functional modules 22, which may, for example, include at least one (preferably rechargeable) battery, at least one antenna, at least one part of the device electronics, at least one data storage device and / or at least one operating element (not visible in the figures respectively) and typically have module sections that are not waterproof, in particular module sections that hinder wet cleaning.

[0059] The coating device 10 according to the present invention can overcome these disadvantages. Figures 2 to 4c The embodiment shown in FIG.

[0060] exist Figure 2 The covering device 10 is shown separately and in an exploded view. The covering device includes a pocket 11, as shown in Figures 4a to 4c As can be seen in the figure, the pocket is provided (suitable) for covering other functional modules 22 to be worn on the back of the head, the head holder 23 and the functional module 21 to be worn on the forehead side and the display device 21. A The phase-spaced module sections 21 B superior.

[0061] The pocket 11 is preferably made of a flexible material, in particular a fabric, film and / or paper material, at least in part. The pocket can be impermeable to organic structures, such as fungal spores, bacteria and / or viruses, which may exist in areas of the output device that cannot be wet cleaned.

[0062] from Figure 2 It can also be seen that pocket 11 has a pocket opening The pocket opening is formed by the edge 11 of the pocket R Surrounding and defined thereby. Edge strip 11 S , that is, edge 11 R The strip area on the forehead can be clamped between the functional module 21 and the display device 21 that needs to be worn on the forehead. A Interval module section 21B In, the pocket 11 is thereby closed; this can be Figure 4a-4c Seen in.

[0063] The holding frame 12 which is likewise surrounded by the encapsulation device 10 serves here for clamping and is designed in the present example as a detachable frame which has two separate, respectively dimensionally stable (rigid) frame elements 12a, 12b and comprises two further elements 12c, 12d. Figure 3 alone and in a manner different from Figure 2 The frame is shown in the perspective of Figure 2 and Figure 3 In the embodiment, the frame is shown in an exploded view corresponding to the disassembled state. In particular, when the retaining frame 12 is connected to the edge strip 11 S Clamped in module section 21 B By establishing this disassembled state, the holding frame can be removed from the functional module 21 that needs to be worn on the forehead side, especially the module section 21 thereof. B The bag 11 is then removed from the output device 20 (preferably without damage).

[0064] The further elements 12c, 12d are used to connect the two frame elements 12a, 12b to each other (at the respective ends of the frame elements). In the embodiment shown, the further elements are designed as oval rings, which are preferably elastic (e.g. at least partially made of rubber and / or silicone). In order to connect the frame elements 12a, 12b, they are hooked onto the fixing elements 12a formed on the ends of the frame elements 12a, 12b. A , 12b A and thereby fixed to the frame element.

[0065] In this example, the frame element 12a forms a receiving groove for the functional module 21 to be worn on the forehead side. Thus, a suitable clamping position of the retaining frame 12 relative to the functional module 21 to be worn on the forehead side is determined, which can be easily achieved by the user.

[0066] like Figure 2 As shown, the frame element 12a has a surface in this example, which includes a surface strip S1 with a strip width B1, which is clamped at the edge strip 11 of the pocket 11. S When facing module section 21 B The frame element 12 b has a surface which includes a surface strip S2 with a strip width B2 which faces the module segment 21 during the clamping process. B In the exemplary embodiment shown, the strip S1 extends in the direction of its strip width B1 parallel to the prescribed viewing direction (see Figure 4c), and the strip S2 extends perpendicularly to the specified viewing direction in the direction of its strip width B2. At least one strip width is preferably at least 1 cm, at least 2 cm or even at least 3 cm. The holding frame can thus realize the edge strip 11 of the pocket 11 R Particularly durable and leak-tight clamping on the functional module 21 to be worn on the forehead side. In the exemplary embodiment shown, the strip widths B1 and B2 differ from one another, where in particular B1>B2 applies.

[0067] Especially from Figure 3 As can be seen in the figure, in the present example, the holding frame 12 has two stabilizing structures 12a, 12b, respectively, which are in the form of pins. S , 12b S The stabilizing structure is provided for interacting with a corresponding mating structure on the output device (not visible in the drawing), i.e. in this example engaging in a corresponding recess or opening in the surface of the functional module 21. The stabilizing structure is used to effect a particularly stable, in particular non-slip fixation of the holding frame 12 on the functional module 21 to be worn on the forehead side when clamped.

[0068] In this example, the two frame elements 12a and 12b also face the display device 21 when they are clamped. A Interval module section 21 B The surface has a three-dimensional profile; due to the viewing angle, it can only be seen Figure 2 The profile of the frame element 12b is seen in; Figure 3 and Figure 4b The profile on the frame element 12a is also shown. In this example, the three-dimensional profile comprises a plurality of profile elements 12a. P , 12b P In the embodiment shown, the profile elements are each designed as granules. The profile is used to generate an uneven force effect at different points during the clamping process, thereby reducing the sliding properties of the bag 11 relative to the holding frame 12.

[0069] exist Figures 4a to 4c In FIG. 1 , an embodiment of an output device kit 100 according to the present invention is shown in different views, the output device kit comprising an output device 20 and a covering device 10 according to the present invention, as shown in FIG. Figure 1a , Figure 1b and Figure 2 As shown in; Figure 4c The output device assembly 100 is shown in use. To better understand the arrangement, Figures 4a to 4c The covered parts are indicated by dotted lines.

[0070] Figure 4a , Figure 4bThe edge strip 11 of the pocket 11 is described S The module section 21 of the functional module 21 to be worn on the forehead and spaced apart from the display device is clamped B In particular, it can be seen that the frame elements 12a, 12b of the holding frame 12 have a connection with the housing element 21. G The adapted shape even reproduces the footprint of the functional module 21 in certain areas, so that when clamped, the functional module is inserted into the holding frame with an exact fit.

[0071] Therefore, in this example, the two openings 12a formed in the holding frame 12 L The pocket 11 is respectively arranged at a housing opening 21 covered by the pocket 11 L Shell opening 21 L The function of the housing opening 21 (for example as a ventilation opening) can thereby remain unchanged, and the housing opening 21 L Can still be covered by the pocket and thus secured.

[0072] The opening 12b arranged in the frame element 12b L It can also be arranged similarly on or in the housing element 21 G On a housing opening in the drawing which is not visible.

[0073] from Figure 4c As can be seen, the pocket 11 with its edge strip 11 S The functional module 21 to be worn on the forehead side is clamped by the holding frame 12 and the display device 21 A Interval module section 21 B Therefore, the pocket 11 is closed by the functional module 21 that needs to be worn on the forehead side. The display device is exposed (or kept free), especially between the user's eyes and the display device 21. A The prescribed observation space S between the two remains unaffected by the covering device 10 (or remains free of the covering device 10).

[0074] In this way of partial covering, the user can conveniently remove the output device kit 100 from the head, for example during interruptions in use, especially during work breaks, and put it on again later without losing the protective effect achieved by the covering device 10 .

[0075] It goes without saying that users can also wear Figure 4c The protective clothing not shown in the figure is also realized between its head and the output device 20 installed together with the covering device 10.
