Support profile with concealed connection system for flat building elements

Abstract

(Main claim): Column or mast profile (1), characterized in that it consists of an extruded material and has a plurality of vertical fastening slots (3) which are designed in such a way that flat structural elements (2) can be inserted horizontally and are fixed in a form-fitting manner by means of securing pins (5).

Description

1. Technical area:

[0001] The invention relates to a support profile, particularly in the form of a column or mast profile, used for fastening flat building elements in modular construction and fastening systems. Typical applications include signage systems, street furniture, fencing, enclosures, railings, and other architectural structures. 2. Known state of the art:

[0002] Existing systems typically require visible fastening methods such as screws, clamps, or adapters to attach flat structural elements to support profiles. These solutions are often visually disruptive, require additional assembly tools, and generally offer limited flexibility regarding the alignment of the structural elements. Furthermore, visible fasteners present potential points of attack for vandalism, as they can be loosened or damaged with simple tools. This not only compromises the stability but also the longevity and safety of the structure. 3. Problem underlying the invention:

[0003] The objective of the invention is to provide a modular fastening system that enables a concealed, tool-free, and stable connection between support profiles and flat building elements. The system should be visually appealing, offer high flexibility in the alignment of the building elements, and ensure easy replacement and reusability without the need for additional tools such as screws, clamps, or adapters. 4. Protection sought for:

[0004] The invention comprises a column or mast profile with vertical mounting slots that allow for the insertion of flat structural elements. The connection is made via a positive locking pin that can be inserted without tools. If present, filler profiles close unused slots, thus providing additional stability and an aesthetic appearance. 5. Commercial use:

[0005] The system is suitable for numerous applications, including signage systems, fencing, street furniture, modular information systems, railings, and enclosures. It enables quick and flexible assembly, easy replacement and addition of components, and the reusability of components. 6. Advantageous effect of the invention:

[0006] The carrier profile according to the invention offers several significant advantages over conventional solutions: • It allows the attachment of flat components on up to eight sides, providing maximum flexibility in the design of modular systems. • The concealed connection system ensures a visually appealing and stable installation without the need for tools. The locking pin enables quick, tool-free fastening through lateral insertion and positive locking via a 90° turn using the key-lock principle. The stable press fit further increases the strength of the connection. • Unused fastening slots can be closed with filling profiles, which visually enhances the construction and also stabilizes it. • The components are clamped using end caps, which makes the entire construction robust and durable. 7. Example of the invention:

[0007] A typical application example is a mast profile that serves as a supporting element of a modular information system. Flat structural elements, such as signs, are inserted horizontally into the mounting slots and secured with locking pins. Vertical fixation and stability are ensured by filler profiles that close unused slots. Finally, the ends of the structure are braced with end caps, ensuring a uniform and stable installation. 8.

Claims

[1] (Main claim): Column or mast profile (1), characterized by that it consists of an extruded material and has a plurality of vertical fastening slots (3) which are designed in such a way that flat components (2) can be inserted horizontally and are fixed in a form-fitting manner by means of securing pins (5). [2] (Filling profile): Filling profile (4), characterized by that it is inserted precisely into unused fastening slots (3) of the support profile (1), closes them completely, takes over the vertical fixation of the flat components (2) and ensures additional optical and structural stability. [3] (Securing pin A): Safety pin (5), characterized by that it is inserted laterally into the flat component (2), this is fixed in a form-fitting manner by a 90° rotation using the key-lock principle and is connected stably and permanently to the support profile (1) by a press fit. [4] (Securing pin B): Safety pin (6), characterized by that it is inserted laterally into fastening slots of the flat component (2), fixes it positively and connects it stably and permanently to the support profile (1) by means of a press fit. [5] (End cover): End cover (6), characterized by that it is attached to the ends of the support profile (1), clamps the flat components (2) against each other and at the same time protects the fastening slots (3) from external influences such as dirt, moisture or mechanical damage.
