Description

Technical Field

[0001] This invention relates to the field of outdoor recreational and fitness facilities technology, specifically to sunbathing nude bathing areas. Background Technology

[0002] With the fast pace of modern urban life, people's demand for physical and mental health and contact with nature is increasing. Sunbathing, as a traditional leisure and health practice, is believed to help promote vitamin D synthesis, improve mood, and enhance overall comfort. In recent years, in some countries and regions, specific outdoor locations that allow natural nude sunbathing (i.e., "naturism") have gradually become popular among a niche group. These locations aim to allow users to completely relax their minds and bodies under natural light, freeing themselves from the constraints of clothing and enjoying direct contact with sunlight and air.

[0003] However, existing outdoor spaces or facilities suitable for nude sunbathing generally suffer from a series of prominent problems that severely restrict their promotion, user experience, safety, and sustainable operation: First, privacy protection is severely inadequate. Most venues rely solely on simple geographical isolation (such as being located on a remote beach or in a corner of a forest) or a single barrier (such as a low fence or curtain), which cannot effectively block external views or the prying eyes of modern devices such as drones. This causes users to feel psychologically tense and makes it difficult for them to truly relax, and it also easily leads to social disputes and management conflicts.

[0004] Secondly, the facilities are poorly planned and lack human-centered and scientific design. Existing spaces are often just open areas, not zoned according to changes in sunlight angle and intensity. Users cannot choose between different lighting conditions such as full sun, partial shade, or complete shade, potentially leading to sunburn or a monotonous experience. The supporting rest facilities are rudimentary, usually consisting of fixed reclining chairs or mats, the materials of which can easily burn the skin under direct sunlight, and the safe storage of personal belongings cannot be guaranteed, making them prone to loss.

[0005] Third, hygiene and health management are lacking. Public areas are cleaned and disinfected infrequently, posing a risk of cross-infection among different users. The lack of basic hygiene facilities such as foot cleaning makes it easy for sand and dirt to be brought into the rest areas. Furthermore, the lack of scientific guidance on lighting makes it difficult for users to determine the appropriate duration of sun exposure, and there are no convenient tips on skin care and hydration, potentially leading to health risks.

[0006] Fourth, behavior management and service guidance are inefficient. Venues rely heavily on voice broadcasts or written notices to disseminate rules, which is ineffective in multilingual environments and can easily disrupt a quiet atmosphere. There is a lack of effective monitoring mechanisms for key behaviors such as prohibiting photography, commercial filming, and harassment, leading to delays in dispute resolution. Service requests depend on language communication, which presents obstacles and is inefficient.

[0007] Fifth, it has poor adaptability to climate and environment. The ground material can easily burn the skin under the scorching sun, and there are no measures to deal with rainy or windy weather, resulting in the site's utilization rate being greatly affected by the weather. There is a lack of proactive design for regulating the microclimate, such as using vegetation to reduce local temperature and increase humidity.

[0008] Finally, the access and management mechanisms are lax. Most venues use open or simple registration systems, which fail to effectively screen users and hold them accountable, making it difficult to maintain the core order and culture of the venue.

[0009] Therefore, there is an urgent need for a systematic solution in the existing technology that can comprehensively address issues such as privacy protection, scientific zoning, facility safety and hygiene, non-disruptive management, environmental adaptation, and standardized operation, thereby creating a safe, private, healthy, comfortable, and well-managed sunbathing area to meet the needs of specific groups for a high-quality natural health and wellness experience, and to provide a technological foundation for its sustainable and low-disruption operation. Summary of the Invention

[0010] The purpose of this invention is to provide a sunbathing nude bathing area by establishing multiple visual barriers, implementing a reservation and written code of conduct confirmation system, configuring dedicated rest and storage facilities, setting up independent and enclosed auxiliary function partitions, and establishing a comprehensive visual signage and non-verbal service system, thereby ensuring hygiene, safety and climate adaptability, while creating a quiet, comfortable and privacy-respecting natural light environment for users.

[0011] To achieve the above objectives, this invention employs the following technical solution: a sunbathing area, the location of which must meet the basic conditions of sufficient natural sunlight and a relatively quiet environment. The site selection requires professional evaluation to ensure continuous, unobstructed sunlight exposure during operating hours, while its acoustic and geographical environment should be relatively independent, far from public roads, residential areas, or other high points that may cause visual interference. To achieve absolute privacy, the visual isolation barrier adopts a composite, continuous, and uninterrupted structure. The first barrier is typically fixed, such as a solid wall at least 2.5 meters high or a densely planted evergreen tree belt, designed to block distant external views. Adjacent to the inner side is a second barrier, which can be an adjustable anti-glare panel, a dense trellis, or a high-density hedge, designed to eliminate any gaps in the view caused by angle or height, and further absorb noise, thereby forming a complete, closed visual and auditory isolation zone around the site, ensuring that internal activities are invisible and undetectable to the outside.

[0012] Furthermore, based on the site's solar trajectory map, zones with varying light intensities need to be precisely calculated and delineated. "Full-sun zones" are located in open areas without any permanent obstructions, designed to ensure users receive ample sunlight. "Partially shaded zones" utilize adjustable awnings, well-designed perforated grilles, or trees of varying density to provide variable, non-full-time shading. "Fully shaded rest areas" are located under fixed structures or fully enclosed roofs, providing space for users to rest, rehydrate, and avoid prolonged sun exposure. Soft partitions separate the zones, such as varying platform heights, low-lying planters, movable misting systems, or different textured paving materials. Simultaneously, a functional signage system using high-contrast colors and simple graphics is installed at zone boundaries and internal nodes to clearly guide users to the function and light level of each area.

[0013] Furthermore, the main body of the facility is an adjustable recliner, whose supporting frame should be made of weather-resistant and corrosion-resistant metal or composite materials. The hinge mechanism has a multi-position locking function, allowing users to adjust the tilt angle from fully reclined to semi-reclining. The supporting surface of the recliner should not be made of ordinary plastic or metal, but should be covered with a composite skin-friendly and heat-resistant layer. This layer is usually composed of an outer layer of high-density moisture-proof fiber fabric and an inner layer of slow-rebound sponge or silicone gel layer, ensuring that the surface temperature remains controllable and the touch is comfortable even after prolonged exposure to sunlight. In a fixed position on each recliner (usually below one armrest or next to the leg), a personal storage box with a physical lock (such as a waterproof padlock or a built-in mechanical combination lock) is integrated. The box must be waterproof, pry-proof, and large enough to hold small personal items, allowing users to securely access them without leaving the recliner.

[0014] Furthermore, changing, showering, and sanitation facilities must not be in an open or semi-open layout, but must be designed as independent, fully enclosed physical cubicles. Each cubicle must have an independent door lock, ventilation, and lighting system, and the walls and doors must meet the prescribed sound insulation and visual obstruction standards. In particular, shower cubicles, in addition to providing hot and cold water mixing valves and handheld showerheads, must have a dedicated, ventilated drying area for clothes hanging on the wall outside the spray area. This area is usually a recessed niche equipped with a heated air curtain or forced ventilation device to ensure that the user's dry clothes do not get wet during showering and are completely isolated from the wet area.

[0015] Furthermore, a standardized visual information communication system, independent of language, will be established within the venue. This system uses universally recognized graphic symbols registered with the International Organization for Standardization (ISO) or relevant international conventions as its core design language, combined with directional arrows, boundary lines, and color coding (e.g., red for prohibition, green for permission, and blue for information) to form a comprehensive signage network. Its content covers three main categories: 1) Area guidance, such as directions to changing areas, areas with different lighting levels, and emergency exits; 2) Safety information, such as anti-slip, hydration, and sunlight intensity warning icons; 3) Behavioral prohibitions, such as prominent icons prohibiting photography, smoking, and running. The purpose of this system is to achieve efficient and unambiguous information delivery across language barriers through purely visual symbols, thereby replacing potentially noisy voice broadcasts and maintaining a quiet atmosphere within the venue.

[0016] Furthermore, strengthening the cleaning and disinfection process hinges on implementing a "one-use, one-clean" system for rest facilities that users directly contact. This means that immediately after the previous user leaves, the support surfaces of the reclining chairs, adjustment handles, and the inside and outside of storage boxes must be wiped and disinfected using a diluted disinfectant, and the cleaning time must be recorded. In addition, foot-washing pools are mandatory at all key entrances from the changing area to the main rest area. These shallow pools contain a cleaning solution with a low concentration of disinfectant, have a non-slip grating at the bottom, and clearly display graphic signs saying "Please clean your feet before entering." These pools are supervised by administrators or designed through facility design (such as mandatory pathways) to ensure that every entrant uses them, reducing the introduction of sand and debris into the core area.

[0017] Furthermore, pre-printed paper guide materials should be provided at the information service desk or fixed information board at the entrance of the venue. These materials should be based on publicly published, consensus-based health advice. They should primarily include: 1) a reference table for recommended sun exposure duration, providing suggested maximum single exposure time and daily cumulative exposure time based on different UV index ranges (e.g., low, medium, high, very high); 2) skin care knowledge, introducing general methods for basic pre- and post-sun care; and 3) a hydration guide, emphasizing the necessity of increasing water intake during sunbathing. All materials must clearly include disclaimers such as "This information is a general health tip and does not constitute any medical advice. Please consult your doctor for specific advice," ensuring that no form of automated assessment, personalized diagnosis, or health intervention is involved.

[0018] Furthermore, a real-name reservation registration system will be implemented to control the density of people within the same time period. Those who successfully make a reservation must sign a written "Code of Conduct Confirmation" before entry. This code explicitly prohibits the following behaviors in the form of clauses: using any equipment for photography, videography, or audio recording; conducting any form of commercial promotion or business activity; and harassing, disturbing, or making unwelcome contact with others in any form. The venue will have clearly marked administrators conducting regular and irregular patrols to supervise the implementation of the code. In addition, the venue has established and strictly enforces an age-restricted policy, explicitly refusing entry to minors under the age of eighteen through methods such as verifying identification documents, and prominently displaying this information in reservation information, entry notices, and venue signage.

[0019] Furthermore, the system requires each prospective participant to provide a valid medical examination report from a licensed medical institution, outlining specified criteria, upon registration or before their first visit. These criteria typically include screening for common infectious diseases that can be transmitted through close contact or public facilities (e.g., medical examination for skin diseases). The report must be within a specified validity period (e.g., three months). The venue operator is required to verify the authenticity and validity of the report and establish a confidential personal health record (only the conclusion page and validity information are retained). This system aims to reduce the potential risk of disease transmission in public places from the outset and is a proactive measure to protect the health and safety of all users.

[0020] Furthermore, the focus is on improving the comfort and safety of the site under different climatic conditions through engineering techniques. Specifically, this includes: 1) Ground treatment: In areas with high activity levels, especially in areas exposed to full sunlight, laying specialized anti-slip and heat-resistant flooring materials with high reflectivity and low heat capacity (such as specially treated wood, composite flooring, or light-colored anti-slip coatings) to prevent excessive heat absorption and burns. 2) Wind environment management: Installing appropriately high transparent or semi-transparent windbreaks (such as high-strength polycarbonate panels or windbreak nets) upwind of the site's prevailing wind direction to reduce wind speed without affecting natural lighting. 3) Ecological regulation: Scientifically planning and planting native drought-resistant, low-flying trees, shrubs, and ground cover plants. These plants not only enhance visual isolation but also effectively regulate local temperature and humidity through transpiration and shading effects, creating a more pleasant microclimate and reducing irrigation and maintenance needs.

[0021] This invention provides a sunbathing area with the following beneficial effects: 1. This design, by establishing at least two continuous, opaque visual barriers, effectively blocks external views, creating a highly private physical and psychologically safe space for users. This multi-barrier structure not only blocks the possibility of peeping from different angles and distances but also significantly reduces the tension and anxiety users experience during nude sunbathing, allowing them to fully relax and focus on enjoying natural light. Compared to traditional methods relying solely on a single barrier or natural vegetation for isolation, this solution provides a more thorough and reliable guarantee of privacy, meeting the core functional requirements of this type of venue and providing a solid foundation for privacy protection for users.

[0022] Based on the scientific division of sunlight into full-sunlight zones, partially shaded zones, and fully shaded rest areas, supplemented by soft partitions and clear signage, this achieves refined management and efficient utilization of natural light resources. This zoning design allows users to choose the most suitable area based on their individual tolerance to sunlight intensity, daily physical needs, or sun therapy plans, thus flexibly controlling the amount and duration of sunlight received. It effectively avoids the problems of overexposure or insufficient experience that may occur in traditional sunbathing areas due to monotonous lighting conditions, improving comfort and safety, and enabling users with different physical conditions and preferences to obtain a personalized, healthier, and more scientific sunbathing experience.

[0023] Equipped with an adjustable reclining chair made of skin-friendly, heat-resistant material and a personal storage box with a physical lock, this design significantly optimizes the user experience. The adjustable angle allows users to choose the most comfortable posture for sunbathing, while the skin-friendly, heat-resistant material avoids the discomfort or burn risks that metal or ordinary plastic materials may cause at high temperatures. The adjacent storage box solves the problem of securely storing personal belongings, especially small items such as mobile phones and wallets, allowing users to sunbathe and relax without worry. This combination of facilities enhances convenience, safety, and overall comfort.

[0024] The changing, showering, and sanitation facilities are all designed as independent, fully enclosed cubicles, with a dedicated area for hanging dry clothes within the shower cubicles. This fully protects users' privacy and personal hygiene in non-public areas. The fully enclosed cubicles completely eliminate potential disturbances or privacy breaches during these transitions, aligning with the overall high level of privacy of the venue. The dedicated area for hanging dry clothes effectively solves the common problem of clean clothes getting wet or soiled after showering, demonstrating meticulous consideration for user flow and needs, and enhancing the convenience and quality of the changing and showering experience.

[0025] An internationally recognized graphic signage system covering area guidance, safety instructions, and behavioral prohibitions was established. This system, coupled with written confirmation of behavioral guidelines and administrator patrols, created an efficient, clear, and binding non-verbal management and order maintenance system. The graphic signage system transcends language barriers, intuitively conveying key information to users from diverse cultural backgrounds and maintaining a tranquil atmosphere. The combination of written commitments and patrols explicitly prohibits photography, commercial activities, and harassment. Age restrictions further contribute to creating and maintaining a safe, quiet, and respectful public nude sunbathing environment through both rules and enforcement, effectively preventing potential disputes and protecting the rights and experience of all users.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] How to use: Step 1: Reservation and Admission This bathhouse operates on a reservation and registration system. When making a reservation, you must confirm in writing that you will abide by the bathhouse's code of conduct, including the prohibition of recording, commercial activities, and harassment. Minors under the age of 18 are explicitly prohibited from entering. To ensure public health and safety, in accordance with the health access policy, you need to provide a valid medical examination report with the required criteria when making a reservation or upon entry. Entry will only be permitted after verification.

[0031] Step Two: Entry and Initial Preparations Upon arrival, you will see two or more continuous, opaque visual barriers surrounding the bathhouse to ensure privacy for activities inside. Before entering the main passage, please clean your feet at the foot-cleaning pool at the entrance, following the signage system; this is a mandatory hygiene step. Printed reference tables for recommended lighting duration, skin care knowledge, and hydration tips will be available at the entrance or information area for your reference only and should not replace professional medical advice.

[0032] Step 3: Familiarize yourself with the environment and regulations Upon entering the venue, you will see a comprehensive visual guidance and behavioral guidelines signage system. This system uses internationally recognized graphic symbols to indicate areas, inform you of safety instructions and prohibited behaviors, replacing audio announcements. Please remain quiet and read them carefully. Venue administrators will patrol the premises to supervise the implementation of the behavioral guidelines.

[0033] Step 4: Changing clothes and storing belongings Please proceed to the separate changing, shower, and toilet areas. These facilities are all fully enclosed cubicles to ensure your privacy. Each shower cubicle has a dedicated area for hanging dry clothes. After changing, you can store your personal belongings in the nearby lockable storage boxes in the rest area, and please keep the keys safe.

[0034] Step 5: Choose an area and rest. The bathing area is divided into zones with varying levels of sunlight, including fully sunlit areas, partially shaded areas, and fully shaded rest areas. These zones are separated by soft partitions and functional signage. Please choose the appropriate zone based on your needs and the lighting guidelines.

[0035] Each area is equipped with a dedicated adjustable reclining chair with a skin-friendly, heat-resistant surface. Before use, please ensure the facility has undergone a "one-use-one-clean" disinfection process. You can adjust the reclining chair to a comfortable position according to the angle of the sunlight.

[0036] Step 6: Precautions during the experience During your experience, please adhere to the agreed-upon code of conduct to maintain a quiet and private atmosphere. The bathing area has been climate-adapted, with non-slip and heat-resistant flooring, transparent windbreaks, and native drought-resistant plants planted around the perimeter to improve microclimate and enhance comfort. Please be mindful of your own comfort, stay hydrated, and manage your time in the sun appropriately; if necessary, move to a shaded area.

[0037] Step 7: Leaving the venue After your session, please return the recliner to its initial angle and retrieve your personal belongings. You are welcome to use the shower stalls for cleaning and to use the drying area within. When leaving, please keep the passageway clear and dispose of your waste in the designated containers.

[0038] Example: Example 1: An Example Regarding Site Selection and Visual Barriers This embodiment specifically illustrates the site selection and visual barrier implementation of the "sunbathing beach". Site selection is the foundation for constructing this beach. We selected a south-facing hillside area away from urban noise and with slightly undulating natural terrain. This location meets the core requirement of "sufficient sunshine", receiving continuous and direct sunlight from 10:00 AM to 4:00 PM. Simultaneously, its "quiet environment" is achieved through natural conditions, surrounded on three sides by low hills, effectively blocking external road noise and creating a naturally tranquil atmosphere.

[0039] To achieve an "opaque visual barrier," we established a three-tiered, continuous isolation system. The first barrier is a densely planted wall of evergreen shrubs, exceeding three meters in height, along the site's boundary line. The selected species are native trees with lush foliage that never shed their leaves. Approximately five meters inside the shrub wall, a second barrier is constructed—a seamless solid fence made of treated bamboo and wood, with its top slightly angled inwards to further prevent external views. Within the bathing area, the various functional zones are separated by the aforementioned shrubs, low walls, or dense decorative hedges, forming a third layer of soft visual isolation. This ensures that even between people moving between different areas, sightlines are effectively blocked. This multi-layered, continuous, opaque barrier completely isolates direct views between external and internal areas from a ground-level perspective, fully guaranteeing the "privacy of activities within the premises," allowing users to relax completely without fear of being spied on.

[0040] Example 2: An Example of an Internal Illumination Zoning and Signage System This embodiment specifically illustrates the construction of the internal area division and signage system of the "Sunbathing Nude Beach". While ensuring overall privacy, to meet the different sunlight needs of users, we have carried out a refined lighting zoning plan within the site. Specifically, three distinct areas are defined: the central open lawn, the highest point and without any obstruction, is designated as the "full sun area"; in the peripheral areas, "partially shaded areas" are constructed using the natural canopies of large trees or by erecting wooden trellises with approximately 50% openwork; in addition, "fully shaded rest areas" are established under the canopies of several large trees and inside a simply designed pavilion.

[0041] The different light levels of each area are not separated by hard walls, but by "soft" partitions. For example, a boundary line inlaid with pebbles and planted with low-growing herbs separates the "full sun area" from the "partially shaded area." At the entrance to each area, there are "functional directional signs." These signs belong to a complete "visual guidance and behavioral norms signage system," the core of which is "internationally recognized graphic symbols." For example, a sun graphic represents the "full sun area," half sun and half leaf represents the "partially shaded area," and a house silhouette represents the "fully shaded rest area." The system also includes arrows indicating the direction of changing rooms and showers, as well as prohibition symbols for "no photography" and "no noise." All guidance, instructions, and prohibitions are conveyed through this non-verbal graphic system, completely "replacing voice announcements" and maintaining the overall tranquil atmosphere of the bathhouse.

[0042] Example 3: Example regarding rest facilities and personal belongings storage This embodiment specifically demonstrates the dedicated rest facilities and accessories provided for users within the "Sunbathing Nude Beach". Instead of ordinary beach chairs or fixed benches, the beach is uniformly equipped with specially designed "adjustable reclining chairs". The frames of these chairs are made of lightweight and corrosion-resistant aluminum alloy. The backrest and seat are adjusted to multiple positions via a simple and reliable buckle device, allowing users to easily adjust from a fully reclined position to a semi-reclining or reclining posture to accommodate different sunbathing angles.

[0043] The recliner's surface is made of a skin-friendly, heat-resistant material. Specifically, the parts that come into direct contact with the skin are covered with a dense layer of natural rattan. This rattan material undergoes special treatment, resulting in a smooth, burr-free surface with excellent heat conductivity and dissipation, preventing it from getting hot even under prolonged sunlight. A thin padding layer underneath the rattan provides both support and enhanced comfort. On the right side of each recliner, a personal storage box with a physical lock is fixed to the floor. Made of engineering plastic, this waterproof and moisture-proof box has enough space to hold a mobile phone, wallet, keys, and a small book. The lock is a traditional rotary combination lock, allowing users to set their own combination, eliminating the need to carry or rent keys and providing secure, convenient storage for personal belongings.

[0044] Example 4: Example of sanitary facilities and cleaning and disinfection procedures This embodiment details the design of sanitary facilities and the sanitary management process within a "sunbathing nude bathing area." The changing rooms, showers, and sanitary facilities are all designed as "independent, fully enclosed cubicles." These cubicles are modularly constructed with sound and heat-insulated walls, offering a compact yet fully functional interior. Each cubicle has an independent door lock, ensuring absolute privacy during use.

[0045] Specifically, each shower stall has a designated drying area for clothes. Located opposite the showerhead, this elevated niche with a waterproof cover houses a foldable waterproof hanging rod. Users can place clean clothes here beforehand or hang swimsuits here to drain after use, completely avoiding getting them wet. The bathhouse implements an enhanced cleaning and disinfection process, one key aspect of which is the "one-use-one-clean" approach to rest facilities. After each user leaves, the staff immediately wipes down and disinfects the surfaces of the lounge chairs, adjustment handles, and adjacent storage boxes with a disinfectant-containing cloth. Additionally, "footwashing pools" are installed at key entrances connecting main functional areas, such as the entrance from the changing area to the sunbathing lawn. These shallow pools contain disinfectant and have anti-slip particles on the bottom, requiring each user to step in and remain for several seconds to clean their feet, preventing the introduction of sand or potential germs into the core rest area.

[0046] Example 5: An Example of Access Control and Behavior Management This embodiment specifically illustrates the comprehensive access and behavior management system implemented at the "Sunbathing Nude Beach." This system aims to safeguard the health and experience quality of users from the outset. Firstly, the beach implements a "reservation and registration access system." All potential users must make reservations in advance through official channels and, at the time of reservation, "confirm in writing online their compliance with explicit behavioral guidelines." These guidelines are clearly listed in the form of clauses, prohibiting behaviors including but not limited to: using any equipment for "image recording" such as photography or videography; engaging in "commercial activities" such as product promotion or membership recruitment; and any form of "harassment" that makes others uncomfortable. The guidelines explicitly include a clause stating that "minors under the age of 18 are explicitly prohibited from entering the premises."

[0047] Secondly, a "health access system for participants" is implemented in parallel. After a successful reservation, or upon first entry, users are required to "provide a medical examination report for specified items." Specified items typically include screening for basic and infectious diseases. The report must be issued by a licensed medical institution; bathhouse staff only conduct a formal verification, aiming to "prevent the spread of infectious diseases," but not to conduct any medical diagnosis. During bathhouse operation, administrators conduct irregular, non-intrusive "patrols and supervision," primarily observing for violations of behavioral guidelines, such as image capture or loud conversations, and promptly providing silent visual reminders (such as displaying prohibition signs) or gentle written prompts to maintain order and atmosphere within the premises in a silent manner.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
