Description

Technical field

[0001] The present invention relates to a fastening and receiving system for nets according to the preamble of claim 1. The system is designed for receiving, fixing, and holding net-like surface elements and is particularly suitable for fastening to building structures. It is preferably designed for use on building openings such as windows, doors, balcony openings, loggias, terrace openings, light wells, or similar openings. Furthermore, the system can also be used indoors, for example, for fastening decorative or design nets, such as a net-like surface element above a bed or in comparable living or utility areas. The technical field encompasses mechanical holding and locking systems with a releasable, mechanical clamping action for receiving nets of various types. State of the art

[0002] Various systems for fastening nets are known in the prior art. These include, in particular, rigid frame systems in which nets are clamped into surrounding frames, as well as adhesive systems in which nets are bonded directly or indirectly to the building structure. Screw and cable tensioning systems are also known, especially for fastening animal protection or cat nets, as well as hook-and-loop or magnetic systems for temporary net fastening.

[0003] However, these well-known solutions have significant drawbacks. Rigid frame systems require precise dimensional accuracy, are complex to install, and typically only allow for net replacement or retensioning after complete disassembly. Adhesive systems transfer the safety-relevant holding forces to the adhesive bond itself, which can lead to insufficient safety, especially under higher mechanical loads, weather conditions, or in outdoor applications. Screw or cable tensioning systems require modifications to the building structure, are visually obtrusive, and can only be installed with tools. Hook-and-loop or magnetic systems often have limited holding power and are only suitable to a limited extent for safety-critical applications.

[0004] What all these systems have in common is that changing the mesh, retensioning it, or adapting it to different opening sizes is only possible with considerable installation effort or requires disassembly of the fastening elements. Uniform load distribution along the fastening is often not achieved, which can lead to localized overloads. Description of the invention

[0005] The task is accomplished by a fastening and mounting system comprising an elongated base element and a separate mounting and locking element. The base element can be attached to a building structure and features a receptacle. The mounting and locking element can be inserted into this receptacle and rotated relative to the base element. Clamping surfaces are formed between the base element and the mounting and locking element, which serve to hold a net. By rotating the mounting and locking element relative to the base element, the net is mechanically clamped and fixed. The net is secured solely by the mechanical clamping and locking action of the mounting and locking element, while the base element merely serves to position the system on the building structure.

[0006] According to the invention, the aforementioned problem is solved according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous embodiments and further developments of the fastening and receiving system according to the invention are specified in the dependent claims.

Brief description of the drawings

[0008] Further objectives, features, advantages and application possibilities of the fastening and receiving system according to the invention will become apparent from the following description of an exemplary embodiment with reference to the drawings.

[0009] The drawings show Fig. 1 the fastening and receiving system according to the invention, consisting of a base element and a receiving and locking element in an advantageous embodiment in perspective view; Fig. 2 the fastening and receiving system according to the invention with two base elements which are combined to form a double strip in perspective view; Fig. 3 a basic element in section; Fig. 4 a receiving and locking element in section. Implementation of the invention

[0010] As from Fig.As can be seen in Figure 1, the fastening and receiving system has a base element 10, which is elongated and designed for attachment to a building structure. A receptacle 100 is formed in the base element 10, preferably extending along the longitudinal axis of the base element. A receiving and locking element 11 can be inserted into this receptacle 100 and is rotatable relative to the base element 10. Clamping surfaces 101 and 110 are formed between the base element 10 and the receiving and locking element 11. A mesh is arranged between these surfaces and mechanically fixed by rotating the receiving and locking element 11.

[0011] The receiving and locking element 11 exhibits different locking characteristics depending on its rotational position relative to the base element 10. This allows the system to be adapted to different load situations. In a first rotational position, a weaker positive and / or non-positive coupling is achieved, which is particularly suitable for easier mesh replacement or decorative applications. In a further rotational position, a stronger positive and / or non-positive coupling is achieved, which is suitable for safety-relevant applications. The advantage of this design is that the same system can meet both low and high mechanical requirements without the need to replace components.

[0012] The receptacle 100 of the base element 10 can have several geometrically different profile sections that can be engaged with the receptacle and locking element 11 in different rotational positions. These profile sections can have projecting and / or recessed geometric elements 102 that interact with corresponding geometric elements 111 of the receptacle and locking element 11. This interaction creates defined locking levels that enable reproducible and secure locking. The advantage lies in clearly defined user guidance and increased operational reliability.

[0013] The receiving and locking element 11 can have several geometrically different profile sections designed to interact with the receiving element 100 and / or the profile sections of the base element 10. This allows different combinations of corresponding profile sections to produce different locking effects. One combination can result in a weaker positive and / or force-fit connection, while another combination results in a stronger positive and / or force-fit connection. The advantage lies in the finely graduated adjustability of the holding force.

[0014] The receiving and locking element 11 can form several spatially spaced clamping points, thus achieving a mechanical multi-point clamping of the network. This results in an essentially linear load distribution along the base element 10, thereby avoiding localized overloads and increasing the service life of the system.

[0015] Several basic elements 10 can be modularly connected to accommodate different opening sizes. Furthermore, the basic elements 10 can be aligned orthogonally to each other to form a building opening along its entire perimeter. The advantage of this design lies in its high flexibility in adapting to different opening geometries.

[0016] The receiving and locking element 11 can preferably be inserted into the base element 10 without tools and is rotatable. This enables easy assembly and convenient net replacement. The clamping surfaces 101 and 110 can be designed to receive different nets, in particular insect nets, pollen nets, dust protection nets, animal protection nets, or metal nets, as well as nets made of textile, polymeric, metallic, or metallized materials and of woven, braided, grid, or mesh structures. Furthermore, the clamping surfaces 101 and 110 can be designed to receive nets of different material thicknesses within a specified thickness range, thus achieving a high degree of application versatility.

[0017] Two base elements 10 can be combined to form a double strip 12, enabling a particularly stable fastening. The system can be designed for mounting on the outside of building openings. The base element 10 and / or the receiving and locking element 11 can be made of a cutable or breakable plastic material, allowing for easy adaptation to different lengths and shapes.

[0018] The attachment of the base element 10 to the building structure can serve solely for positioning, while the securing of the net is achieved exclusively by the receiving and locking element 11. The receiving and locking element 11 can be designed to be releasable, allowing repeated release, retensioning, and re-locking of the net. The receiving element 100 and / or the receiving and locking element 11 can have a defined rotation and detent range within which locking occurs in at least one stable detent position. The base element 10 can be designed for drill-free attachment to the building structure, in particular by means of an adhesive bond.

[0019] The receiving and locking element 11 can have at least one projecting actuating element 112, which serves for the manual rotation and / or positioning of the receiving and locking element 11 relative to the base element 10. The actuating element 112 can be designed as a handle, lug, tab, or lever and is preferably accessible from the outside when the system is assembled. The advantage lies in its ergonomic and intuitive operation.

[0020] In one embodiment, the fastening and mounting system is used to attach an animal safety net to a balcony opening. In another embodiment, the system is used to attach a decorative net indoors, for example, as a net-like surface element above a bed. The design and function of the system remain identical in all embodiments. List of reference numbers 1.
