Description

Lattice structure and head mounting device including the same

[0001] The embodiment(s) of the present disclosure relate to a lattice structure and a head-mounting device including the same.

[0002] Electronic devices intended for portability, such as electronic notebooks, portable multimedia players, mobile communication terminals, and tablet PCs, are generally equipped with a display device and a battery, and have bar-shaped, folder-shaped, or sliding-shaped appearances due to the shape of the display device or battery. Recently, as the performance of display components and batteries has improved and they have become smaller, electronic devices that can be worn on parts of the body such as the wrist or head, or in the form of clothing (hereinafter referred to as "wearable electronic devices") are emerging.

[0003] Examples of wearable electronic devices include head-mounted devices (HMDs), smart glasses, smart watches (or bands), contact lens-type devices, ring-type devices, clothing-type, shoe-type, and glove-type devices. These body-worn electronic devices are easy to carry and can improve user accessibility.

[0004] For example, a ‘head-mounted wearable device (hereinafter simply referred to as a “head-mounted device”)’ is a device used while being worn on a user’s head or face, and can be classified into a see-through type that provides augmented reality (AR) and a see-closed type that provides virtual reality (VR). A see-through head-mounted wearable device can be implemented, for example, in the form of glasses, and can provide information such as buildings and objects within the user’s field of vision in the form of images or text to the user. A see-closed head-mounted wearable device outputs independent images to each of the user’s eyes and can provide excellent immersion by outputting content (games, movies, streaming, broadcasts, etc.) provided from a mobile communication terminal or external input in the form of video or audio to the user wearing it.

[0005] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. No claim or determination is made as to whether any of the foregoing may be applied as prior art in relation to the present disclosure.

[0006] The present disclosure may provide a lattice structure and a head mounting device including the same.

[0007] According to one embodiment, the head mounting device may include a first support portion that supports the user's face when the user wears the head mounting device; a second support portion that supports the user's occipital region; and a connecting portion that connects the first support portion and the second support portion. The second support portion constitutes a part of the exterior of the head mounting device and may include a plurality of lattice patterns defined by a plurality of nodes and a plurality of rods, which are continuously arranged along a first direction and a second direction different from the first direction. The plurality of lattice patterns may form a plurality of lattice pattern layers (L1, L2, L3) that are spaced apart in a third direction perpendicular to the first direction and / or the second direction, and are formed in a curved manner when viewed in a cross-section cut along the third direction. The plurality of lattice pattern layers may include a plurality of lattice pattern layers in which the cross-sectional area of ​​a plurality of nodes or a plurality of rods included in a layer located relatively inward among the plurality of lattice pattern layers is formed to be smaller than the cross-sectional area of ​​a plurality of nodes or a plurality of rods located relatively outward among the plurality of lattice pattern layers.

[0008] According to one embodiment, the lattice structure constitutes the exterior of the lattice structure and may include a plurality of lattice patterns in which a lattice pattern defined by a plurality of nodes and a plurality of rods is continuously arranged. The plurality of lattice patterns may be spaced apart in the height direction and may form a plurality of lattice pattern layers that are curved when viewed from a cross-section cut along the height direction. The plurality of lattice pattern layers may include a plurality of lattice pattern layers in which the cross-sectional area of ​​a plurality of nodes included in a layer located relatively inward among the plurality of lattice pattern layers is formed to be smaller than the cross-sectional area of ​​a plurality of nodes located relatively outward among the plurality of lattice pattern layers.

[0009] According to one embodiment, the head mounting device may include a first support portion that supports the user's face when the user wears the head mounting device; a second support portion that supports the user's occipital region; and a connecting portion that connects the first support portion and the second support portion. The second support portion constitutes a part of the exterior of the head mounting device and may include a plurality of lattice patterns defined by a plurality of nodes and a plurality of rods, which are continuously arranged along a first direction and a second direction different from the first direction. The plurality of lattice patterns may form a plurality of lattice pattern layers that are spaced apart in a third direction perpendicular to the first direction and / or the second direction, and are formed in a curved manner when viewed in a cross-section cut along the third direction. The center of a first lattice pattern included in one of the plurality of lattice pattern layers and the center of a second lattice pattern included in an adjacent lattice pattern layer and corresponding to the first lattice pattern can be aligned to face in the same direction. Additionally, the plurality of lattice pattern layers can be linearly connected such that a rod connecting one of the plurality of lattice pattern layers and an adjacent lattice pattern layer is substantially parallel to an imaginary line connecting the centers of the lattice patterns.

[0029] Throughout the attached drawings, similar parts, configurations, and / or structures may be assigned similar reference numbers.

[0030] In OST (optical see-through) / VST (video see-through) product lines that require ergonomic design, such as head-mounted devices, AR glasses, or VR glasses, design differentiation elements compared to existing mobile phones / tablets must be present, or sensory elements such as high-quality fit and comfortable cushioning must be provided to the user. In addition, it is essential to stably secure the relatively heavy device set on the face without shaking, and to provide a lightweight feel so that the user does not experience discomfort even when wearing it for a long time.

[0031] In this disclosure, various embodiments may be disclosed for an OST / VST product (e.g., a head mounting device) that includes a back cushion pad supporting the back of the user's head among various OST / VST product families, with design differentiation elements to provide high-quality usability (e.g., fit and / or cushioning) and light weight.

[0032] Existing OST / VST product lines are mainly manufactured using injection molding, making it difficult to apply complex designs and thus difficult to differentiate designs.

[0033] The present disclosure may disclose a back cushion pad capable of applying complex designs by utilizing a 3D printing method, and an OST / VST product (e.g., a head mounting device) including the same. In particular, the present disclosure may provide a back cushion pad with a lattice structure.

[0034] Meanwhile, it is required to provide a high-quality user experience with design differentiation elements, minimize contamination, and facilitate easy cleaning when contaminants are present. In particular, as it is a part that comes into direct contact with the body, the residue of contaminants such as sweat, cosmetics, and hair entanglement must be minimized, and even if contaminants are present, they must be easily removable.

[0035] When a lattice structure is applied to existing rear cushion pads, the connection method between the patterns of adjacent layers generally takes the form of an X-shaped entanglement. However, if the rear cushion pad is entangled in an X shape, there may be a problem where contaminants are prone to remaining on the pad and are difficult to clean.

[0036] Accordingly, the present disclosure can disclose a rear cushion pad that enables design differentiation and provides a high-quality user experience and weight, while ensuring stain resistance by making it more difficult for contaminants to remain and allowing easy cleaning even if contaminants are present, and an OST / VST product including the same (e.g., a head mounting device).

[0037] The following description relating to the attached drawings may provide an understanding of various exemplary embodiments of the present disclosure, including the claims and their corresponding contents. While the exemplary embodiments disclosed in the following description include various specific details to aid understanding, they are to be considered as one of various exemplary embodiments. Accordingly, those skilled in the art will understand that various changes and modifications to the various embodiments described in the present disclosure may be made without departing from the scope and technical spirit of the disclosure. Additionally, for clarity and brevity, descriptions of well-known functions and configurations may be omitted.

[0038] The terms and words used in the following description and claims are not limited to their literal meanings but may be used to clearly and consistently describe an embodiment of the present disclosure. Accordingly, it will be apparent to a person skilled in the art that the following description of various embodiments of the disclosure is provided for illustrative purposes, not for the purpose of limiting the scope of the rights or the disclosure defined as equivalent thereto.

[0039] Unless the context clearly indicates otherwise, it should be understood that the singular forms of "a," "an," and "the" include a plural meaning. Thus, for example, "component surface" can be understood to include one or more of the component surfaces.

[0069] FIG. 2 is an exploded perspective view of a head mounting device (200) according to one embodiment of the present disclosure. FIG. 3 is an assembled perspective view of a head mounting device (200) according to one embodiment of the present disclosure. FIG. 4 is a drawing showing a view of the head mounting device (200) from above according to one embodiment of the present disclosure. FIG. 5 is a drawing showing a view of the head mounting device (200) from one side according to one embodiment of the present disclosure. FIG. 4 may show a plan view of the head mounting device (200), and FIG. 5 may show a side view of the head mounting device (200).

[0070] In describing the embodiments of FIGS. 2 to 5 and the following embodiments, an orthogonal coordinate system (X, Y, Z) may be illustrated for convenience of explanation. For example, the X-axis direction of the orthogonal coordinate system may represent the width direction of the head mounting device (200), the Y-axis direction may represent the length direction of the head mounting device (200), and the Z-axis direction may represent the height direction of the head mounting device (200). In describing the arrangement relationship between the components of the present disclosure, the arrangement of one component in front (e.g., front) or behind (e.g., rear) of another component may refer to an arrangement relationship on the Y-axis. For example, the arrangement of one component in front (e.g., front) of another component may be understood as the component being located in the +Y-axis direction relative to the other component.

[0071] Referring to FIGS. 2 through 5, the head mounting device (200) is an electronic device that can be worn by a user (wearable), and the user can visually perceive surrounding objects or the environment even while wearing the head mounting device (200). All wearable devices that can be worn on a user's head can be applied to the head mounting device (200) of the present disclosure.

[0072] The head-mounted device (200) can acquire and / or perceive visual images of objects or environments in the direction the user is looking or the head-mounted device (200) is facing using a camera module, and can receive information about objects or environments from an external electronic device via a network. The head-mounted device (200) can provide the information about the received objects or environments to the user in an auditory or visual form. For example, the head-mounted device (200) can provide the information about the received objects or environments to the user in a visual form using a display module through a display member (e.g., display unit (201) and / or lens unit (220)). By implementing information about objects or environments in a visual form and combining it with actual images (or video) of the user's surrounding environment, the head-mounted device (200) can implement Augmented Reality (AR), Virtual Reality (VR), Mixed Reality (MR), and / or Extended Reality (XR). The display component can provide information about surrounding objects or environments to the user by outputting a screen in which an augmented reality (or virtual reality, mixed reality, and / or extended reality) object is added to an actual image (or video) of the user's surrounding environment. In the detailed description below, this may be assumed to be in a state where the user is wearing a head-mounted device (200).

[0073] Referring to FIGS. 2 and 3, the head mounting device (200) may include a display unit (201), a wear frame (202), and / or an adjustment unit (203), and may further include at least one support unit (240, 250) disposed in a portion that comes into direct contact with the user's body. The wear frame (202) is provided as a pair and may extend from the display unit (201) respectively. The adjustment unit (203) is coupled with the wear frame (202), and when viewed in a plan view, the head mounting device (200) may have a closed curve shape. For example, the display unit (201), the wear frame (202), and / or the adjustment unit (203) may be arranged or coupled to form a closed curve. The user can adjust the wearing state of the head mounting device (200) by sliding the adjustment unit (203) relative to the wear frame (202).

[0074] According to various embodiments, when a user is wearing a head-mounting device (200), the display unit (201) may be positioned substantially corresponding to the user's eyes. According to one embodiment, the display unit (201) may include a display body (210), a glass (230) positioned on one side of the display body (210), and a lens unit (220). The lens unit (220) may be positioned on the other side of the display body (210) and may include at least one lens (221) and a lens cover surrounding the at least one lens (221). Visual information output from the display panel of the display body (210) may be transmitted to the user through the lens unit (220). In the embodiment of FIG. 3, the lens unit (220) is shown to include a pair of lenses (221) corresponding to the user's eyes, but is not necessarily limited thereto, and may, for example, provide visual information to the user's eyes by outputting it through a flat display panel. The display unit (201) of the flat panel display may include, for example, a liquid crystal display panel (LCD), an organic light emitting diode (OLED), and / or a micro-LED. According to one embodiment, the display unit (201) may include a projector and an optical waveguide structure. For example, the display unit (201) may output visual information using a projector and provide it to the user's eyes through the optical waveguide structure.

[0075] According to various embodiments, the display unit (201) may substantially block actual images of the surrounding environment and provide visual information (e.g., images or videos implementing a virtual space) output through a projector or display panel to the user. For example, the head-mounting device (200) may implement virtual reality and provide it to the user. In another embodiment, the display unit (201) may include a camera module (not shown) and may capture the surrounding environment in the direction the user is looking and provide it to the user through a projector or display panel. In some embodiments, the head-mounting device (200) may extract information regarding images or videos captured in real time from data stored in itself or data collected through a network environment (e.g., the first network (198) and / or the second network (199) of FIG. 1), and combine the captured images or videos with the extracted information to provide them to the user. For example, the head-mounting device (200) may implement augmented reality and provide it to the user. In another embodiment, the display unit (201) can provide the user with an actual image of the surrounding environment by transmitting it, and can visually provide the user with information regarding an image or video captured through the camera module (211).

[0076] The wearable frame (202) includes a pair of wearable frames (202) each extending from the display unit (201) and may be positioned facing the side of the user's head while worn on the user's body. In some embodiments, the wearable frame (202) may be manufactured at least partially integrally with the display unit (201). For example, the wearable frame (202) may include an inner frame positioned facing the user's body and an outer frame positioned facing the external space, and either the inner frame or the outer frame may be formed integrally with the display unit (201).

[0077] The wear frame (202) is configured to move relative to the adjustment unit (203) using the wheel (2031) of the adjustment unit (203), so that the length of the wear frame (202) can be substantially reduced or expanded. For example, as the adjustment unit (203) slides relative to the wear frames (202), the overall closed curve shape can be expanded or reduced, and the user can adjust the close contact or support between the head mounting device (200) and the user's body (e.g., head). With respect to the adjustment unit (203), the wear frames (202) are arranged substantially symmetrically, and the direction of movement of the adjustment unit (203) for one of the two wear frames (202) and the direction of movement of the adjustment unit (203) for the other of the two wear frames (202) can be substantially symmetrical.

[0078] The support members (240, 250) may include a first support member (240) positioned adjacent to the display member (201) and a second support member (250) positioned adjacent to the control member (203). According to one embodiment, the first support member (240) may be attached to the rear of the display member (201), and the second support member (250) may be attached to the front of the control member (203). When the head mounting device (200) is worn on the user's body, the first support member (240) may be in contact with or supported on the user's face or forehead, and the second support member (250) may be in contact with or supported on the back of the user's head. For example, the user may use the head mounting device (200) while wearing it on their head, and the support members (240, 250)(s) may relieve or distribute the load applied to the user's body due to the weight of the head mounting device (200). The support members (240, 250) of the present disclosure may be configured to support the user's head in a fit while ensuring that the user does not experience discomfort when wearing the head mounting device (200).

[0079] According to various embodiments, although not illustrated, the head mounting device (200) may further include an auxiliary frame. The auxiliary frame may, for example, extend from the display unit (201) and be connected to the control unit (203) and may be supported on the upper part of the user's head. For example, the head mounting device (200) may be worn on the user's body in a state of contact or support on the user's forehead, the rear of the head, and / or the upper part of the head. If the auxiliary frame is included, the head mounting device (200) may include an additional support member that is in direct contact with the upper part of the user's head.

[0080] The support members (240, 250) of the present disclosure may include an elastic material. According to one embodiment, at least one of the first support member (240) and the second support member (250) included in the support members (240, 250) may include an elastic material, and each or part thereof may be referred to as an 'elastic support member' or a 'cushion member'.

[0081] In the embodiments of FIGS. 3 to 5 of the present disclosure, the second support member (250) is illustrated as comprising an elastic material. The second support member (250) may be configured to restore its shape by elastic repulsion even if its shape is deformed. For example, the second support member (250) may include a material that returns to its original state when pressure is released, even if pressure is applied to the second support member (250) and the second support member (250) is compressed and its shape collapses or sinks. The second support member (250) of the present disclosure may not only include an elastic material but may also be structurally configured to return to its original state when pressure is released. To this end, the second support member (250) may include a lattice structure. According to one embodiment, the second support member (250) itself may be referred to as a 'lattice structure (250)'. For convenience of explanation, the following description focuses on an embodiment in which the second support member (250) includes a lattice structure, and the second support member (250) may be referred to as the lattice structure (250). However, the scope of the present disclosure is not limited to the second support member (250) including the lattice structure, but may also include an embodiment in which the first support member (240) includes the lattice structure, and an embodiment in which both the first support member (240) and the second support member (250) include the lattice structure.

[0082] The present disclosure aims to provide a lattice structure (e.g., a second support member (250)) that can stably support the user's head without causing inconvenience to the user, while also providing a lattice structure (e.g., a second support member (250)) that is easy to clean and has high stain resistance.

[0083] FIG. 6 is a drawing showing a contaminant adsorbed on a lattice structure (250') according to some embodiment. FIG. 7 is a drawing showing a contaminant adsorbed on a lattice structure (250'') according to some embodiment.

[0084] When a user wears and / or stores a head-mounting device (e.g., the head-mounting device (200) of FIGS. 2 to 5), the surface of the support may become contaminated due to the adsorption and transfer of various substances (e.g., dust, foreign matter). As shown in FIGS. 6 and 7, when the support includes a lattice structure (250', 250''), due to the characteristics of the lattice structure consisting of multiple layers, the outermost part of the lattice structure adjacent to the outside may be easy to clean, but the inner part of the lattice structure may not be easy to clean (see arrows in FIGS. 6 and 7). For example, in the case of an embodiment such as FIGS. 6 and 7, the lattice patterns included in the lattice structure are arranged irregularly, so the cleaning solution does not come into direct contact with the lattice patterns, making cleaning difficult.

[0085] The present disclosure provides a lattice structure with enhanced stain resistance by facilitating easy cleaning of the inner portion, and a head mounting device including the same.

[0086] FIG. 8 is a drawing showing a lattice structure according to one embodiment of the present disclosure. FIG. 9 is an enlarged drawing of a lattice structure according to one embodiment of the present disclosure. For example, the lattice structure (250) of FIG. 8 may be an enlarged drawing of the second support member (250) of FIG. 2 to FIG. 5, and in the description below, the second support member (250) is referred to as the “lattice structure (250).”

[0087] A lattice structure (250) according to one embodiment of the present disclosure may include a plurality of lattice patterns (e.g., P1, P2 of FIG. 9). The lattice structure (250) may include a plurality of layers (e.g., L1, L2, L3 of FIG. 10) that are spaced apart from each other and at least a portion of which includes a curved surface, and the plurality of lattice patterns (e.g., P1, P2 of FIG. 9) may come together to form a single layer, and the plurality of layers (e.g., L1, L2, L3 of FIG. 10) may come together to form the entire lattice structure (250).

[0088] Referring to FIG. 9, the unit lattice pattern included in the lattice structure (250) may be composed of a combination of multiple nodes (2501) and multiple rods (2502). FIG. 9 shows six nodes (2501-1, 2501-2, 2501-3, 2501-4, 2501-5, 2501-6) as examples of multiple nodes (2501). Additionally, FIG. 9 illustrates a number of rods (2502-1, 2502-2, 2501-3, 2501-4, 2501-5, 2501-6) greater than six nodes (2501-1, 2501-2, 2501-3, 2502-4, 2502-5, 2502-6, 2502-7, 2502-8, 2502-9) as an example of a plurality of rods (2502). It should be noted that the shapes and / or numbers of the plurality of nodes (2501) and / or rods (2502) illustrated in FIG. 9 are provided for illustrative purposes only and are not necessarily limited to the scope of the present disclosure.

[0089] According to one embodiment, a rod (e.g., 2502-1) may be placed between one node (e.g., 2501-1) and another adjacent node (e.g., 2501-2), and a node (e.g., 2501-1) may be placed between one rod (e.g., 2502-1) and another adjacent rod (e.g., 2502-2). For example, one node (2501) among a plurality of nodes (2501) may be an element placed between two or more rods (2502) to connect, join, link, and / or intersect (intersection or junction) the two or more rods (2502). One rod (2502) among a plurality of rods (2502) may be an element for connecting a plurality of nodes (2501) placed on the same layer to each other, or for connecting a plurality of nodes (2501) placed on different layers to each other.

[0090] The "multiple lattice patterns" included in the lattice structure (250) may be formed by repeatedly arranging at least one type of pattern (or unit cell form) having a repetitive form or design. According to one embodiment, the multiple lattice patterns may be formed by gathering at least one type of pattern and spaced apart by a certain distance, or by arranging at least one type of pattern continuously.

[0091] According to one embodiment, the plurality of lattice patterns included in the lattice structure (250) may all form patterns of the same shape, but depending on the embodiment, they may also form patterns of different shapes. That is, the plurality of lattice patterns included in the lattice structure (250) may include two or more types of patterns. FIGS. 8 and 9 disclose a lattice structure (250) including two types of different shapes of patterns (P1, P2). The lattice structure (250) may, for example, form a hexagonal pattern (P1) by combining six nodes (2501) and six rods (2502), as shown in FIGS. 8 and 9, or form a square pattern (P2) by combining four nodes (2501) and four rods (2502). According to one embodiment, some of the multiple nodes (2501) constituting one pattern (e.g., hexagonal pattern (P1)) (e.g., 2501-1, 2501-6) and some of the multiple rods (2502) (e.g., 2502-6) may be some of the multiple nodes (2501) and some of the multiple rods (2502) constituting an adjacent other pattern (e.g., square pattern (P2)). However, this is merely an example and the scope of the invention is not limited to the embodiments of FIGS. 8 and 9. Depending on the embodiment, various other forms of patterns may be applied.

[0092] For example, other types of patterns may be applied to the lattice structure (250), and may include a greater number of pattern types. As other types of patterns, various types of patterns such as triangular patterns, circular patterns, and circular-linear combination patterns may be applied, and may be applied differently depending on various embodiments.

[0093] The present disclosure can be manufactured using a 3D printing method to enable the application of complex designs such as a lattice structure (250). In addition, by creating a lattice structure (250) using a 3D printing method, it is easy to provide a lattice structure (250) that has a light weight so that when a user attaches a head-mounting device to their head, a relatively heavy OST / VST device set is stably fixed without shaking, while the user does not experience discomfort even when wearing it for a long time.

[0094] A lattice pattern composed of multiple nodes (2501) and multiple rods (2502) may have an opening (or hole) formed in its center.

[0095] The lattice structure (250) of the present disclosure has an opening within the pattern, which allows for a significant reduction in volume compared to conventional general integrated rear cushion pads, thereby enabling weight reduction. Additionally, if a flexible / elastic material such as polyurethane (PU) is used as the raw material for the 3D printing method, there is an advantage in maximizing the cushioning sensation. Meanwhile, regarding the rear cushion pad, the cushioning sensation may vary depending on the shape and size of the pattern; for example, filling the inside of the pattern more and reducing the size may lead to increased rigidity / elasticity but an increase in weight, whereas conversely, filling the inside of the pattern less and increasing the size may reduce weight but decrease rigidity / elasticity. In the present disclosure, since the lattice structure (250) is manufactured using a 3D printing method, a lattice structure (250) with high rigidity / elasticity and low weight can be provided according to the required product specifications.

[0096] FIG. 10 is a cross-sectional view of a lattice structure (250) according to one embodiment of the present disclosure. FIG. 11 is a cross-sectional view of a lattice structure (250) according to one embodiment of the present disclosure. FIG. 12 is a cross-sectional view of a lattice structure (250) according to one embodiment of the present disclosure. FIG. 13 is a cross-sectional view of a lattice structure (250) according to one embodiment of the present disclosure.

[0097] FIG. 10 may show a cross-section of the lattice structure (250) of FIG. 8 cut in the A-A' direction. FIG. 11 may show a cross-section of the lattice structure (250) of FIG. 8 cut in the B-B' direction. FIG. 12 may show a cross-section of the lattice structure (250) of FIG. 8 cut in the C-C' direction. FIG. 13 may show a cross-section of the lattice structure (250) of FIG. 8 cut in the D-D' direction.

[0098] The lattice structure (250) of the present disclosure constitutes a part of the exterior of the lattice structure (250) (or head mounting device) and may include a plurality of lattice patterns defined by a plurality of nodes (2501) and a plurality of rods (2502) that are continuously arranged along a first direction and a second direction different from the first direction. Here, the first direction may be the length direction (or width direction) of the lattice structure (250), and the second direction may be the width direction (or length direction) of the lattice structure (250).

[0099] The plurality of lattice patterns may be spaced apart in a third direction perpendicular to the first direction and / or the second direction, and may form a plurality of lattice pattern layers that are curved when viewed in a cross-section cut along the third direction.

[0100] Referring to FIGS. 10 through 13, the lattice structure (250) may include a plurality of lattice pattern layers. Here, "a plurality of lattice pattern layers" may mean that at least three or more lattice pattern layers are gathered to form a plurality of layers. Referring to FIG. 9, "a plurality of lattice pattern layers" may mean that a plurality of lattice patterns are continuously connected in the length direction or width direction to form a single lattice pattern layer, and that such lattice pattern layers are spaced apart in the height direction to form a plurality of layers. One of the plurality of lattice pattern layers and another adjacent layer may be connected through a rod (2502). For example, the embodiment of FIG. 10 discloses a partial view of the lattice structure (250), and the lattice structure (250) referenced in FIG. 10 may include a first lattice pattern layer (L1), a second lattice pattern layer (L2), and a third lattice pattern layer (L3) spaced apart from each other in the height direction. For convenience of explanation, the first lattice pattern layer (L1) may be referred to as the outermost layer closest to (or exposed to the outside) the outside of the lattice structure (250), and the third lattice pattern layer (L3) may be referred to as the innermost layer positioned at the innermost part of the lattice structure (250).

[0101] According to one embodiment, the lattice structure (250) may consist of an innermost and outermost layer, and / or an intermediate layer between the innermost and outermost layers, all of which may be lattice pattern layers. For example, FIG. 10 may illustrate a lattice structure (250) in which a first lattice pattern layer (L1), a second lattice pattern layer (L2), and a third lattice pattern layer (L3) all include a plurality of lattice patterns.

[0102] According to one embodiment, at least a portion of the lattice structure (250) may include a curved surface. That the lattice structure (250) includes a curved surface may mean, for example, that a plurality of patterns included in the outermost lattice pattern layer of the lattice structure are not arranged on a single flat plane when viewed in cross-section. For example, referring to FIG. 10, the first lattice pattern layer (L1) located at the outermost edge of the lattice structure (250) may form a curve in the AA' cross-section of the lattice structure (250). Corresponding to the shape of the first lattice pattern layer (L1), the second lattice pattern layer (L2) and the third lattice pattern layer (L3) located at the middle and innermost sides of the lattice structure (250) may form a curve in the AA' cross-section of the lattice structure (250). According to one embodiment, a plurality of nodes (2501) (2501a) included in the first lattice pattern layer (L1), a plurality of nodes (2501) (2501b) included in the second lattice pattern layer (L2), and a plurality of nodes (2501) (2501c) included in the third lattice pattern layer (L3) may be aligned radially when viewed in cross-section as shown in FIG. 10.

[0103] In the present disclosure, a lattice structure (250) can be provided that can stably support the user's head without causing inconvenience to the user, while also being easy to clean and having high stain resistance.

[0104] To this end, the lattice structure (250) of the present disclosure provides a lattice structure (or head mounting device) comprising a plurality of lattice pattern layers (e.g., L1, L2, L3), wherein the cross-sectional area of ​​a plurality of nodes (2501) included in a layer located relatively inward among the plurality of lattice pattern layers is formed to be smaller than the cross-sectional area of ​​a plurality of nodes (2501) located relatively outward among the plurality of lattice pattern layers. The cross-sectional area of ​​a plurality of nodes (2501) included in any one layer located relatively inward among the plurality of lattice pattern layers may be formed to be smaller than the cross-sectional area of ​​a plurality of nodes (2501) in another layer located relatively outward among the plurality of lattice pattern layers. According to one embodiment, when comparing any two lattice pattern layers among the plurality of lattice pattern layers, the cross-sectional area of ​​a plurality of nodes (2501) in a lattice pattern layer located relatively inward may be formed to be smaller than the cross-sectional area of ​​a plurality of nodes (2501) in a lattice pattern layer located relatively outward.

[0105] According to one embodiment, with respect to a plurality of first nodes (2501a) for forming a lattice pattern of a first lattice pattern layer (L1), a plurality of second nodes (2501b) for forming a lattice pattern of a second lattice pattern layer (L2), and a plurality of third nodes (2501c) for forming a lattice pattern of a third lattice pattern layer (L3), the lattice structure (250) of the present disclosure may be formed such that the cross-sectional area (or size) of the nodes decreases as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Alternatively, the lattice structure (250) of the present disclosure may be formed such that the cross-sectional area (or size) of the nodes remains at least the same as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers.

[0106] In FIG. 10, it can be seen that the cross-sectional area (or size) 'A1' of the first node (2501a) for forming the lattice pattern of the first lattice pattern layer (L1) is larger than the cross-sectional area (or size) 'A2' of the second node (2501b) for forming the lattice pattern of the second lattice pattern layer (L2). It can also be seen that the cross-sectional area (or size) 'A2' of the second node (2501b) for forming the lattice pattern of the second lattice pattern layer (L2) is larger than the cross-sectional area (or size) 'A3' of the third node (2501c) for forming the lattice pattern of the third lattice pattern layer (L3). That is, A1 > A2 > A3. However, it is not necessarily limited to this, and depending on the embodiment, the cross-sectional area (or size) of a node for forming a lattice pattern of one layer (e.g., a second node (2501b)) and a node for forming a lattice pattern of another layer adjacent thereto (e.g., a third node (2501c)) may be formed to be the same.

[0107] According to one embodiment, the lattice structure (250) of the present disclosure may provide a lattice structure (or head mounting device) comprising a plurality of lattice pattern layers (e.g., L1, L2, L3), wherein the cross-sectional area of ​​a plurality of rods (2502) included in a layer located relatively inward among the plurality of lattice pattern layers is smaller than the cross-sectional area of ​​a plurality of rods (2502) located relatively outward among the plurality of lattice pattern layers. The description of the cross-sectional area of ​​the plurality of nodes (2501) described above may be applied to the description of the cross-sectional area of ​​the plurality of rods (2502).

[0108] The plurality of lattice pattern layers (e.g., L1, L2, L3) of the present disclosure may include a plurality of lattice pattern layers (e.g., L1, L2, L3) in which the cross-sectional area of ​​a plurality of nodes (2501) and / or a plurality of rods (2502) included in a layer located relatively inward among the plurality of lattice pattern layers is formed to be smaller than the cross-sectional area of ​​a plurality of nodes (2501) and / or a plurality of rods (2502) located relatively outward among the plurality of lattice pattern layers. The comparison of cross-sectional areas may be performed, for example, only between nodes when the cross-sectional area of ​​a node placed on the same layer is larger than the cross-sectional area of ​​a rod. Alternatively, the cross-sectional area of ​​a rod placed on the same layer may be compared only between rods when the cross-sectional area of ​​a rod placed on the same layer is larger than the cross-sectional area of ​​a node. Furthermore, alternatively, when the cross-sectional area of ​​a node placed on the same layer and the cross-sectional area of ​​a rod are similar, the nodes may be compared with each other, but generally or additionally, the rods may also be compared with each other.

[0109] According to one embodiment, the cross-sectional area of ​​the plurality of lattice patterns included in the plurality of lattice pattern layers may be formed to decrease as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Alternatively, the lattice structure (250) of the present disclosure may be formed such that the cross-sectional area of ​​the plurality of lattice patterns included in the plurality of lattice pattern layers is at least equal as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Here, the cross-sectional area of ​​the lattice pattern may be the area of ​​the lattice pattern defined by the plurality of nodes (2501) and the plurality of rods (2502). For example, the cross-sectional area of ​​the first pattern (P1) in FIG. 9 may be the area of ​​the part (e.g., opening (or hole)) connected by 6 nodes and 6 rods, and the cross-sectional area of ​​the second pattern (P2) may be the area of ​​the part (e.g., opening (or hole)) connected by 4 nodes and 6 rods.

[0110] Additionally, the lattice structure (250) of the present disclosure may be aligned such that the center of a first lattice pattern included in one of the plurality of lattice pattern layers and the center of a second lattice pattern included in an adjacent lattice pattern layer and corresponding to the first lattice pattern face in the same direction. The lattice structure (250) of the present disclosure may have a structure such that, when viewed in cross-section, the extension direction of a rod connecting the plurality of lattice pattern layers of the lattice structure (250) from the outer layer to the inner layer is substantially parallel to an imaginary line connecting the centers of the lattice patterns included in the adjacent layer. Referring to FIG. 10, such a structure may be referred to as an offset lattice structure.

[0111] The first lattice pattern layer (L1) of the present disclosure is a lattice surface layer formed along the outermost surface of the lattice structure (250), and as it extends inward, the layers within it may exist in an offset form relative to the first lattice pattern layer (L1). Among a plurality of lattice pattern layers (e.g., L1, L2, L3), the lattice patterns in each lattice pattern layer may be vertically aligned in a 1:1 ratio with the patterns of adjacent layers. Referring to FIGS. 10 and 11, for example, when the lattice pattern of the first lattice pattern layer (L1) is defined by a plurality of first nodes (2501a) and a plurality of first rods (2502a), the lattice pattern of the second lattice pattern layer (L2) is defined by a plurality of second nodes (2501b) and a plurality of second rods (2502b), and the lattice pattern of the third lattice pattern layer (L3) is defined by a plurality of third nodes (2501c) and a plurality of third rods (2502c), the lattice pattern of the first lattice pattern layer (L1) and the lattice pattern of the second lattice pattern layer (L2) can be formed to correspond to each other. Additionally, the lattice pattern of the second lattice pattern layer (L2) and the lattice pattern of the third lattice pattern layer (L3) can be formed to correspond to each other. According to one embodiment, a line connecting the center (2503a) of the lattice pattern of the first lattice pattern layer (L1) and the center (2503b) of the lattice pattern of the second lattice pattern layer (L2), and a line connecting the center (2503b) of the lattice pattern of the second lattice pattern layer (L2) and the center (2503c) of the lattice pattern of the third lattice pattern layer (L3) may be formed to lie substantially in a straight line. The center of the lattice pattern (250) of the present disclosure may refer to the center of the opening (or hole) of the lattice pattern (250).Referring to FIG. 10 and FIG. 11 together, the plurality of lattice pattern layers can be linearly connected such that a rod (2504a, 2504b) connecting one of the plurality of lattice pattern layers and another adjacent lattice pattern layer is substantially parallel to a virtual axis connecting the centers of the lattice patterns.

[0112] Referring to FIG. 11, the lattice structure (250) of the present disclosure may have a structure in which, when viewed in cross-section, the extension direction of the rods (2504a, 2504b) connecting the outer layer and the inner layer is formed to be approximately similar to the extension direction of an imaginary line connecting the centers of adjacent lattice pattern layers. According to one embodiment, the rod (2504a) connecting the lattice pattern of the first lattice pattern layer (L1) and the lattice pattern of the second lattice pattern layer (L2), and the rod (2504b) connecting the lattice pattern of the second lattice pattern layer (L2) and the lattice pattern of the third lattice pattern layer (L3) may be formed to lie substantially in a straight line.

[0113] In the preceding embodiments, the lattice structure (250) of the present disclosure was described primarily with an embodiment in which the exterior surface includes a curved surface, but the lattice structure (250) of the present disclosure is not necessarily limited thereto and may include at least a flat surface. Referring to FIGS. 11 and 12, the lattice structure (250) of the present disclosure may be formed to have an overall curved exterior shape when viewed from a cross-section of one side, but may be formed to have an overall flat shape when viewed from a cross-section of the other side, as shown in FIGS. 12 and 13.

[0114] Referring to FIGS. 12 and 13, even in a flat lattice structure (250), as a lattice surface layer formed along the outermost surface of the lattice structure (250), the layers located inside may exist in an offset form relative to the first lattice pattern layer (L1) as they extend inward. Among the plurality of lattice pattern layers (e.g., L1, L2, L3), the lattice patterns in each lattice pattern layer may be vertically aligned in a 1:1 ratio with the patterns of the adjacent layers. Additionally, even in a flat lattice structure (250), the cross-sectional area of ​​the plurality of lattice patterns included in the plurality of lattice pattern layers may be formed to be smaller as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Alternatively, the lattice structure (250) of the present disclosure may be formed such that the cross-sectional area of ​​the plurality of lattice patterns included in the plurality of lattice pattern layers is at least the same as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. In addition, in a flat lattice structure (250), the cross-sectional area (or size) of the nodes may be formed to decrease as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Alternatively, the lattice structure (250) of the present disclosure may be formed such that the cross-sectional area (or size) of the nodes is at least the same as one moves from the outer layer to the inner layer of the plurality of lattice pattern layers. Furthermore, the lattice structure (250) of the present disclosure may have a structure in which, when viewed in cross-section, the extension direction of the rod connecting the plurality of lattice pattern layers of the lattice structure (250) as one moves from the outer layer to the inner layer is formed to be approximately similar to the extension direction of a virtual line connecting the centers of adjacent lattice pattern layers.

[0115] FIG. 14 is a drawing showing a cross-sectional structure of another form of a lattice structure according to one embodiment of the present disclosure. In the embodiments of FIG. 8 to FIG. 13, the lattice structure (250) was described as having an overall convex shape, but FIG. 14 shows a concave shape of the lattice structure (250) in a different form.

[0116] The lattice structure (250) of the present disclosure may include at least a portion in which the exterior is formed concavely as shown in FIG. 14, and even in this case, the layers within the lattice structure (250) may exist in an offset form as they go inward from the lattice surface layer (e.g., first lattice pattern layer (L1)) formed along the outermost surface. Among the plurality of lattice pattern layers (e.g., L1, L2, L3), the lattice patterns in each lattice pattern layer may be vertically aligned in a 1:1 ratio with the patterns of adjacent layers. According to some embodiments, when the lattice structure (250) has a concave curved surface, the cross-sectional area of ​​the lattice pattern or the cross-sectional area (or size) of the nodes constituting the lattice pattern may increase from the outer layer to the inner layer. However, the present disclosure provides an embodiment in which, even when having a concave curved surface, the cross-sectional area of ​​the lattice pattern or the cross-sectional area (or size) of the nodes constituting the lattice pattern does not increase from the outer layer to the inner layer in order to maximize stain resistance.

[0117] In this way, multiple lattice pattern layers have an offset shape as they move from the outer layer to the inner layer of the lattice structure (250), and if the centers of the lattice patterns for each layer are aligned, when viewing the inner layer from the outer layer along the direction of the centers of the aligned patterns (e.g., 2503a, 2503b, 2503c in FIG. 10), the lattice pattern of the inner layer may be obscured by the lattice pattern of the outer layer, making it difficult to see the lattice pattern of the inner layer. That is, the lattice structure (250) of the present disclosure may be formed such that when viewing the multiple lattice pattern layers from the outside to the inside, the inner lattice pattern is obscured. In this way, even if external contaminants penetrate the lattice structure, the lattice patterns of the outer layer and the inner layer are well aligned with each other, making it easy to discharge them immediately without jamming. Also, the probability of contaminants adhering to the lattice pattern of the inner layer is reduced, and even if they do adher to the lattice pattern of the inner layer, cleaning can be easy.

[0118] FIG. 15 is a drawing showing the range of the solution when the solution is sprayed onto a lattice structure (250) according to a certain embodiment (comparative embodiment). FIG. 16 is a drawing showing the range of the solution when the solution is sprayed onto a lattice structure (250) according to one embodiment of the present disclosure.

[0119] The lattice structure (250) of the present disclosure can provide a structure that facilitates cleaning when contaminants are deposited on the inside, and also allows the spraying area to evenly extend to the inside area when a pre-designated coating solution (L) is sprayed onto the outer surface and the inner area of ​​the lattice structure (250). The embodiments of FIGS. 15 and 16 are drawings to explain the advantages of the lattice structure (250) of the present disclosure in comparison with a lattice structure according to a comparative embodiment (e.g., the lattice structure (250') of FIG. 6 or the lattice structure (250'') of FIG. 7).

[0120] For example, if a color is to be imparted to the lattice structure, a coating process can be performed on the lattice structure. The coating process may include, for example, a process of spraying a coating solution (L) onto an object (e.g., lattice structure) in a straight line at high pressure. The coating solution (L) must reach and be adsorbed not only to the plurality of nodes (2501) and / or rods (2502) arranged on the outside of the lattice structure but also to the plurality of nodes (2501) and / or rods (2502) arranged on the inside of the lattice structure, so that a uniformly beautiful lattice structure can be formed with a designated color rather than the color of the raw material of the plurality of nodes (2501) and / or rods (2502).

[0121] Referring to FIG. 15, when performing a coating process on a lattice structure (e.g., the lattice structure (250') of FIG. 6 or the lattice structure (250'') of FIG. 7), in order to form a coating area as evenly as possible within the lattice structure, frontal spraying, positive (e.g., +45 degrees) tilted spraying, and / or negative (e.g., -45 degrees) tilted spraying can be performed as shown in the order of the arrows in FIG. 15. For example, when a coating solution (L) is sprayed onto the lattice structure (250', 250'') at high pressure, a column space (CS) that is not reached by the coating solution (L) may be created by a plurality of nodes (2501) and / or a plurality of rods (2502). The CS may be formed parallel to the spraying direction of the coating solution (L). Since the coating solution (L) does not reach the plurality of nodes (2501) and / or plurality of rods (2502) located in the CS, it may be difficult to color the corresponding parts. The CS may be formed differently depending on the arrangement of the plurality of nodes (2501) and / or plurality of rods (2502) included in the lattice structure (250', 250''). The CS formed in the lattice structure (250', 250'') during frontal spraying, the CS formed in the lattice structure (250', 250'') during positive (e.g., +45 degrees) tilted spraying, and the CS formed in the lattice structure (250', 250'') during negative (e.g., -45 degrees) tilted spraying may be different from each other, except for at least some overlapping parts. The more CS is generated per unit area of ​​the lattice structure, in other words, the more parts are obscured by multiple nodes (2501) and / or multiple rods (2502), the less the multiple nodes (2501) and / or multiple rods (2502) placed inside the lattice structure may be colored.

[0122] As illustrated in FIG. 15, according to some embodiments, even if frontal spraying as well as positive (e.g., +45 degrees) tilted spraying and negative (e.g., -45 degrees) tilted spraying are performed, the multiple nodes (2501) and / or multiple rods (2502) may not be evenly colored up to the inner area of ​​the lattice structure (250' or 250''). This may be a problem that occurs in the painting process for, for example, the connection method of the multiple nodes (2501) and / or multiple rods (2502) of the lattice structure (250' or 250'') is an X-shaped intersection. In order to form a coating area more precisely on a lattice structure (250' or 250'') having multiple nodes (2501) and / or multiple rods (2502) that intersect in an X shape as described above, it may have the disadvantage of having to repeatedly perform the frontal spraying, positive (e.g., +45 degrees) tilted spraying, and / or negative (e.g., -45 degrees) tilted spraying, or to apply a significant amount of coating liquid.

[0123] In contrast, the lattice structure (250) illustrated in FIG. 16 may be shown with a connection method of a plurality of nodes (2501) and / or a plurality of rods (2502) having the offset shape described above through the embodiments of FIG. 8 to 14. For the lattice structure (250) of FIG. 16, in order to form a painted area as evenly as possible within the lattice structure, frontal spraying, positive (e.g., +45 degrees) tilted spraying, and / or negative (e.g., -45 degrees) tilted spraying may be performed as shown in the order of the arrows in FIG. 16. Referring to FIG. 16, it can be seen that the inner area of ​​the lattice structure (250) at a relatively deeper position is evenly colored compared to the embodiment of FIG. 15. This has the advantage of reducing the number of processes and / or the consumption of the coating solution compared to the comparative example for an even distribution of the coating area, by, for example, the connection method of the multiple nodes (2501) and / or multiple rods (2502) of the lattice structure (250) forming an offset shape.

[0124] Meanwhile, although the embodiments of FIGS. 15 and 16 mainly describe the coating process for the lattice structure, the same principle can be applied not only to the coating process but also to the cleaning process for the lattice structure. Additionally, the tilted spray angle in FIGS. 15 and 16 can be applied in various ways depending on the embodiment, and it should be noted that although only spraying in the 2D (two-dimensional) direction of the lattice structure is shown in the drawings, spraying in the 3D (three-dimensional) direction can also be considered.

[0125] FIG. 17 is a drawing showing a cross-section of a lattice structure (250) according to one embodiment of the present disclosure. FIG. 18 is a drawing showing a cross-section of a lattice structure (250) according to one embodiment of the present disclosure. Both FIG. 17 and FIG. 18 may show a cross-section of the lattice structure (250) of the embodiment of FIG. 8 cut in the A-A' direction.

[0126] According to one embodiment, the distance between the layers of a plurality of lattice pattern layers of the lattice structure (250) can be formed to be constant. For example, as shown in FIG. 10, the height (HL12) between the first lattice pattern layer (L1) and the second lattice pattern layer (L2) and the height (HL23) between the second lattice pattern layer (L2) and the third lattice pattern layer (L3) can be formed to be substantially the same as each other.

[0127] In contrast, referring to FIG. 17 and FIG. 18, the distance between lattice pattern layers of the lattice structure (250) can be set differently depending on the embodiment. As shown in FIG. 17, the height (HL34) between some lattice pattern layers may be formed higher than the height (HL12, HL23) between other lattice pattern layers. For example, if the lattice structure (250) is formed as in the embodiment of FIG. 17, the rigidity of the outer layer of the lattice structure (250) may be relatively increased, and the rigidity of the inner layer of the lattice structure (250) may be decreased. Alternatively, as shown in FIG. 18, the height (HL12) between some lattice pattern layers may be formed higher than the height (HL23, HL24) between other lattice pattern layers. For example, if a lattice structure (250) is formed as in the embodiment of FIG. 18, the rigidity of the outer layer of the lattice structure (250) may be relatively reduced, and the rigidity of the inner layer of the lattice structure (250) may be increased. Additionally, according to some embodiments, it may be possible to form the height (HL12) between the lattice pattern layers higher than the height (HL23) between other pattern layers, and the height (HL23) between other pattern layers higher than the height (HL34) between yet another pattern layers. By forming the heights between the pattern layers differently in this manner while the lattice structure (250) provides an offset structure, user convenience may be enhanced by increasing the wearability and / or cushioning sensation when the lattice structure (250) is utilized as a second support member of, for example, the head mounting device (200) of FIG. 2 to 5.

[0128] The lattice structure (250) of the present disclosure can be extended to other product families that require lightweight and cushioning, such as watch bands, arm bands, APS covers, helmets, etc., as well as rear cushion pads of OST / VST product families (e.g., head mounting devices).

[0129] According to one embodiment of the present disclosure, a head mounting device (101; 200) may be provided. The head mounting device may include a first support member (240) that supports the face portion of the user when the user wears the head mounting device; a second support member (250) that supports the occipital portion of the user; and a connecting member (202) that connects the first support member (240) and the second support member (250). The second support member (250) constitutes a part of the exterior of the head mounting device and may include a plurality of lattice patterns (P1; P2) in which a lattice pattern defined by a plurality of nodes (2501) (2501) and a plurality of rods (2502) (2502) is continuously arranged along a first direction and a second direction different from the first direction. The plurality of lattice patterns may be spaced apart in a third direction perpendicular to the first direction and / or the second direction, and may form a plurality of lattice pattern layers (L1, L2, L3) that are curved when viewed from a cross-section cut along the third direction. The plurality of lattice pattern layers may be formed such that the cross-sectional area of ​​the plurality of nodes (2501) or the plurality of rods (2502) included in the layer located relatively inward among the plurality of lattice pattern layers is smaller than the cross-sectional area of ​​the plurality of nodes (2501) or the plurality of rods (2502) located relatively outward among the plurality of lattice pattern layers.

[0130] According to one embodiment, the center of a first lattice pattern included in one of the plurality of lattice pattern layers and the center of a second lattice pattern included in an adjacent other lattice pattern layer and corresponding to the first lattice pattern are aligned to face in the same direction, so that when the plurality of lattice pattern layers are viewed from the outside to the inside, the inner lattice pattern can be obscured.

[0131] According to one embodiment, the plurality of lattice pattern layers may be linearly connected such that a rod (2504a, 2504b) connecting one of the plurality of lattice pattern layers and another adjacent lattice pattern layer is substantially parallel to a virtual line connecting the centers of the lattice patterns.

The plurality of lattice patterns may be spaced apart in the height direction and may form a plurality of lattice pattern layers (L1, L2, L3) that are curved when viewed from a cross-section cut along the height direction. The plurality of lattice pattern layers may be formed such that the cross-sectional area of ​​the plurality of nodes (2501) or the plurality of nodes (2501) included in the layer located relatively inward among the plurality of lattice pattern layers is smaller than the cross-sectional area of ​​the plurality of nodes (2501) or the plurality of nodes (2501) located relatively outward among the plurality of lattice pattern layers.

[0142] According to one embodiment, the center of a first lattice pattern included in one of the plurality of lattice pattern layers and the center of a second lattice pattern included in an adjacent other lattice pattern layer and corresponding to the first lattice pattern are aligned to face in the same direction, so that when the plurality of lattice pattern layers are viewed from the outside to the inside, the inner lattice pattern can be obscured.

[0143] According to one embodiment, the plurality of lattice pattern layers may be linearly connected such that a rod (2504a, 2504b) connecting one of the plurality of lattice pattern layers and another adjacent lattice pattern layer is substantially parallel to a virtual line connecting the centers of the lattice patterns.

The second support member (250) constitutes a part of the exterior of the head mounting device and may include a plurality of lattice patterns (P1; P2) in which a lattice pattern defined by a plurality of nodes (2501) (2501) and a plurality of rods (2502) (2502) is continuously arranged along a first direction and a second direction different from the first direction.
