Modular furniture system, consisting of several cube-shaped modules that are connected to each other without tools by form-fitting connections, • characterized in that the modules have a wave-like geometry on their upper and lower edges, which enables locking in two dimensions, wherein the wave-like geometry prevents displacement of the modules in horizontal axes.

Description

1. Technical area:

[0001] The invention relates to a modular furniture system characterized by its flexibility and ease of assembly. In particular, the tool-free locking of the modules through a positive locking mechanism enables a stable and secure connection without the need for additional tools. The system is designed for use in residential, office, and work spaces and offers numerous customization options. 2. State of the art:

[0002] In the area of ​​modular furniture, there are various systems that are assembled using screw connections, plug-in systems, or clamps. These systems often require tools or additional connectors to ensure a stable construction. These additional components can increase assembly time and limit flexibility. Many existing systems offer only limited options for customizing the modules to meet the different needs of users. 3. Object of the invention:

[0003] The objective of the invention is to provide a modular furniture system that allows for quick and easy assembly without the need for tools or additional connectors. The furniture system should be stable, versatile, and particularly user-friendly thanks to the form-fitting modules. Furthermore, the modules should be individually adaptable, allowing them to be supplemented and retrofitted with various inlays, such as doors, flaps, shelves, or drawers. 4. Description of the invention:

[0004] The invention relates to a modular furniture system consisting of several uniform, cube-shaped modules (base module (1)) that can be assembled without tools to form a complex furniture system. The individual modules already represent a complete unit in their basic form and can be used, for example, as a stool, bedside table, or storage element.

[0005] A visualization of the invention is shown in the supplementary Fig. 1 - 3. They show: Fig. 1 basic module Fig. 2 Alternative form factor of a double-width module Fig. 3 System example with a pyramid-shaped arrangement of three basic modules Special geometry of the modules:

[0006] The modules are equipped with a specific wave-like geometry (2) on their top and bottom edges, enabling a positive connection (6). This geometry locks the modules in two dimensions, preventing any shifting along the horizontal axes. The locking is achieved through a repeating pattern (3) that occurs four times on each module edge (on the base module) and allows for a gradual offset (4). This allows the base modules to be connected in four different positions per axis, greatly expanding the combination possibilities and also allowing for center positions. Tool-free assembly and disassembly:

[0007] The entire assembly process takes place without tools. The modules can be easily connected by stacking them together, with the form-fitting geometry stabilizing the connection. Disassembly is just as simple and is achieved by lifting the individual modules. Different form factors:

[0008] The invention also provides for the modules to be produced in different form factors (5) to further increase the variability of the system. This allows modules with different edge lengths to be used, which can also be integrated into the system without tools. Adhering to the grid of the base module, which has a cube edge length of 400mm, is key. This allows modules with, for example, three times the height to be implemented and integrated into the overall system to serve as lockers. Alternatively, modules with four times the width can be implemented to build "bridges". The wave contour remains unchanged, so that modules with multiple edge lengths can be integrated into the overall system. Individual inlays and retrofitting:

[0009] In addition, the modules can be equipped with different inlay variants (8). This includes modules with doors, flaps, shelves or drawers, which can be freely integrated into the standard modules. These inlays can either be installed at the factory or added later to adapt the functionality of the modules to the needs of the user. This allows the user to use the modules as closed storage units or open shelves and to change their configuration at any time as needed. Assembly takes place via a standardized hole pattern (7) into which the extensions can be screwed. In addition, special "add-ons" are possible, such as lids, seat cushions or rolling boards, each of which also accommodates the wave shape and thus enables form-fitting and tool-free assembly. 5. Areas of application:

[0010] The modular furniture system is suitable for a wide range of applications thanks to its flexibility, robustness, and tool-free assembly. In shared apartments and households, it allows for individual customization, for example, as shelving, seating, or room dividers. Exhibition stands benefit from quick, tool-free assembly and reusability for various events. In kindergartens, the modules offer secure storage solutions and child-friendly designs. For offices and co-working spaces, desks, shelves, or room dividers can be easily configured and reconfigured at any time. Event spaces use the modules as flexible seating or stage platforms that can be stored space-savingly after the event. Even in temporary housing solutions, such as emergency shelters, the modules enable quick and efficient use of space. The various inlay options, such as doors or drawers, increase adaptability to individual needs.
