Description

TECHNICAL AREA

[0001] The invention relates to a rotatable platform for mounting on the roof of vehicles, trailers or as a freestanding unit, in particular for the attachment and flexible alignment of roof tents, solar panels, roof boxes, awnings, porches or other equipment and vehicle accessories. STATE OF THE ART

[0002] Conventional roof racks and roof platforms for vehicles are rigidly attached to the vehicle roof. Repositioning items mounted on them, such as roof tents or solar panels, is only possible by repositioning the entire vehicle or through time-consuming disassembly and reassembly. This results in significant inconvenience and limits flexibility of use.

[0003] Especially when using roof tents, it is desirable to optimally orient the tent entrance depending on the wind direction, sun exposure or terrain.

[0004] For solar panels, tracking the sun would significantly increase energy yield. For roof boxes, a rotating function would allow loading from the most convenient position.

[0005] Currently, no solutions exist that allow a load platform on a vehicle roof to rotate 360°. TASK OF INVENTION

[0006] The invention is based on the objective of creating a device that makes it possible to rotate objects mounted on a vehicle roof by 360° without having to move the vehicle or remove the objects. The device should have a high load-bearing capacity, be secure against unintentional rotation while driving, be easy to operate, be modular and adaptable to different vehicle types, and be manufacturable from commercially available components. SOLUTION TO THE TASK

[0007] The problem is solved by a rotatable platform with the features of claim 1. DETAILED DESCRIPTION Basic structure

[0008] The rotatable platform according to the invention is made of a two-part frame consisting of an upper and a lower frame module. Both frame modules are each formed from interconnected profiles and connected to each other via a pivot bearing and a central metal ring. Upper frame module

[0009] The upper frame module forms the platform's top level and supports loads such as roof tents, solar panels, roof boxes, or other equipment. It is constructed from interconnected profiles forming a rectangular or square structure. The upper frame module features flexible mounting options, allowing for versatile accessory installation.

[0010] The size of the upper frame module is variable and can be custom-made depending on the application. Compact dimensions can be chosen for small solar panels, while correspondingly larger frame modules are manufactured for large roof tents. The modular design allows for flexible adaptation to different requirements and vehicle sizes. The corner joints of the upper frame module are firmly connected, forming a stable structure. Internal cross braces can run between the frame sides, providing additional stability.

[0011] The upper frame module is mounted to rotate 360° and can be aligned in any desired direction. Lower frame module

[0012] The lower frame module forms the bottom level of the platform and is mounted on the vehicle roof. It is also made of interconnected profiles and forms a stable base for the entire device.

[0013] The lower frame module is stationary, meaning it does not rotate and remains firmly attached to the vehicle roof. Internal cross braces can also provide additional stability here. Connection of the two frame modules

[0014] The upper and lower frame modules are connected via a pivot bearing and a central metal ring. The central ring serves as a connecting element between the two frame modules and houses the pivot bearing. It transfers the loads from the upper frame module, via the pivot bearing, to the lower frame module and stiffens both frame modules in the middle. The central ring serves solely to connect the two frame modules and is not intended for the direct attachment of objects. pivot bearing

[0015] The pivot bearing enables the upper frame module to rotate 360° relative to the lower frame module. These are commercially available components. The invention lies in the arrangement and combination of these components to form a rotatable vehicle roof platform.

[0016] The slewing bearing can be designed as a rolling bearing, a plain bearing, or a combination of both, and enables low-friction rotation. The slewing bearing is sealed against environmental influences to prevent the ingress of dirt, water, salt, and other corrosive substances, ensuring a long service life even under harsh conditions. Mounting base

[0017] The mounting base is part of the lower frame module or permanently attached to it. It is designed for mounting on the vehicle roof, on trailers, on a roof rack system mounted on top, or as a freestanding unit on a stable surface. The mounting base features adapters that allow installation on various vehicle types, trailers, and roof rack systems. When used freestanding, the mounting base can be installed on a solid surface such as concrete, wood, or metal. The adapters are preferably adjustable to compensate for different distances between mounting points. Locking mechanism

[0018] A locking mechanism prevents unwanted rotation during operation and allows the upper frame module to be fixed in desired positions relative to the lower frame module. The locking mechanism can be designed as a locking bolt, clamping device, electromagnetic brake, or other suitable fixing device. Optionally, defined detents can be provided, enabling precise alignment at specific angles and giving the user haptic or audible feedback when the platform locks into a defined position. FUNCTIONALITY Assembly

[0019] The lower frame module with its mounting base is installed either on the vehicle roof, on a trailer, on roof rails, on an existing roof rack system, or as a freestanding unit on a stable surface. When used freestanding, the platform can be mounted, for example, on a terrace, a flat roof, a campsite, or another solid surface. The swivel bearing connects the lower frame module to the upper frame module, with the central ring serving as the connecting element. The upper frame module is now mounted on the lower frame module, allowing it to rotate 360°. The locking mechanism is then secured in the desired starting position. loading

[0020] Various items can be attached to the upper frame module, such as roof tents via the flexible mounting options of the upper frame module, solar panels via brackets, roof boxes via adapters, equipment boxes that are attached directly to the upper frame module or secured with lashing straps, as well as attachments such as awnings, tents, lighting systems, antennas or other vehicle accessories. rotation

[0021] To realign the platform, release the locking mechanism. Rotate the upper frame module around its vertical axis. The rotation is smooth thanks to the swivel bearing. Rotate the platform into the desired position. If detents are present, the platform will audibly and tactilely click into place. Then, re-engage the locking mechanism. The entire rotation takes only a few seconds and can be performed by one person. APPLICATION EXAMPLES: Roof tent with variable entry option

[0022] A rooftop tent is mounted on the upper frame module. Thanks to its rotating function, the tent entrance can be oriented in any desired direction: away from the wind in unfavorable conditions, towards the view for a beautiful panorama, in the desired direction depending on the position of the sun or terrain, or away from the vehicle for more privacy. This variable entry option significantly increases comfort and allows for optimal adaptation to any camping situation. Reorientation takes only a few seconds. Solar tracking

[0023] Solar panels are mounted on the upper frame module. Manual or automatic rotation throughout the day can significantly increase energy yield compared to a static installation. Two to three manual rotations distributed throughout the day can increase energy yield by 30 to 50 percent. Roof box loading

[0024] A roof box is mounted on the upper frame module. For loading, the box can be rotated into the most convenient position without having to climb a ladder. After loading, the box is rotated back into the desired orientation. This significantly increases loading convenience. Awning alignment

[0025] An awning is mounted on the upper frame module. Its rotating function allows the awning to be optimally positioned to face the sun or shade. As the sun's position changes throughout the day, the awning can be adjusted to provide optimal shade at all times. In windy conditions, the awning can be rotated to provide shelter from the wind. This significantly increases comfort while camping and allows for flexible adaptation to the surrounding conditions. Trailer application

[0026] The platform is mounted on a trailer. Solar panels can be adjusted to track the sun throughout the day without having to move the trailer. A roof tent mounted on the trailer can be optimally positioned depending on its location. With caravan trailers, an awning can always be directed to the desired side by rotating the platform. This is particularly advantageous for extended stays at campsites or outdoor events. Freestanding application

[0027] The platform is mounted as a freestanding unit on a terrace, flat roof, or campsite. Solar panels can be optimally aligned with the sun to achieve maximum energy yield. An awning or sunshade can be rotated according to the sun's position to provide optimal shade. Lighting systems or antennas can be flexibly positioned for outdoor events. The freestanding design offers maximum flexibility without the need for a vehicle. Anti-theft device

[0028] The rotating function allows an object mounted on the upper frame module, such as a roof box or equipment case, to be turned so that latches or openings are difficult to access. Latches can be rotated downwards, between the upper and lower frame modules, or towards the center of the vehicle, where they are hard to reach. In combination with the locking mechanism, this provides additional security against unauthorized opening.

[0029] This feature offers additional theft protection, especially for valuable items or equipment. ADVANTAGES COMPARED TO THE STATE OF THE ART

[0030] The rotatable platform according to the invention offers numerous advantages over conventional rigid roof rack systems.

[0031] There is no longer any need to repark the vehicle to change its orientation, which significantly increases convenience. With roof tents, the entrance can be oriented in any desired direction, offering flexible entry options.

[0032] The energy yield of solar panels can be increased by tracking.

[0033] The device offers flexibility through its versatile applications, ranging from camping and van life to professional use. The flexible mounting options of the upper frame module allow for the easy attachment and removal of a wide variety of items, ensuring modularity.

[0034] The locking mechanism reliably prevents unwanted rotation while driving, thus ensuring safety. By rotating the platform, locks and openings can be moved to hard-to-reach positions, providing additional theft protection. The sealed swivel bearing guarantees a long service life, even under harsh conditions. Rotation can be performed by one person in just a few seconds, making it easy to operate. The invention utilizes commercially available components, simplifying manufacturing. The innovation lies in the combination and arrangement of these components. Adjustable mounting adapters allow the platform to be adapted to various vehicle types, providing flexibility.

[0035] There is no comparable solution on the market. The invention creates a completely new product category and thus offers uniqueness. OPTIONAL EXTENSIONS

[0036] The basic version of the invention can be enhanced with various optional extensions. For more convenient operation or automatic tracking, an electric motor can be integrated to rotate the upper frame module. Control is achieved via remote control, smartphone app, or automatically via sensors. A slip ring can be provided for electrical connections between the upper and lower frame modules, enabling 360° rotation without cable entanglement. This is particularly advantageous when using solar panels or electrical devices on the upper frame module. A mechanical or electronic angle indicator can display the current orientation of the upper frame module, facilitating precise positioning for the user.

[0037] In motorized versions, control can be via remote control or smartphone app, including precise angle adjustment and saving of positions.

[0038] Automatic tracking based on GPS and sun position is also possible.
