Description

Structural system
Technical field
The invention relates to a structural system for implementing, for example, furniture and/or parts of buildings and/or vehicles and/or ships and/or other products or structures. For example, the furniture may be furniture used in offices, apartments, hospitals, schools, production lines, assembly lines, and/or restaurants, and/or short-term furniture implementations, for example, at trade fair. Said parts of the buildings may be, for example, walls, ceilings, and/or floors.
Prior art
Generally in prior art, electrical devices and furniture are installed at the desired location in the furniture or objects in the operating environment with traditional screw connections, as a surface-mounted or flush-mounted housings. Cable installations complicate convertibility, i.e. design freedom that adds value in electrical design.
It is almost impossible to embed electrical wires in a panel-like structural board, so the cables remain visible. The cables are visually messy and make cleaning difficult.
The installation of electrical furniture and devices on the edge of the structural board is challenging with traditional methods due to the installation of the cable and the space required by the connecting wires.
The attachment of a traditional electrical device, such as a socket or luminaire, to a structure or mounting box is usually done with two small screws and is therefore quite weak. The tightness of the attachment is often poor in terms of sound insulation and moisture leakage into the structure.
In the traditional electrical installation method, where the electrical device or furniture is flush-mounted, the structure of the installation accessories required does not take into account sound insulation and/or air leakage. Therefore, applications such as wall or ceiling structures have to be retrofitted.
Publication FI20165157 describes the connection of electrical device and furniture to the surface of a modular furniture part with electrically conductive attachment means, but does not focus and solve any technical installation problems with which the electrical connection and mechanical attachment can be implemented in an electrically safe, installation-friendly manner and to an electrically conductive structural board without the traditional electrical conductors used in the installations. Publication FI201665157 does not take a position on connecting an electrical device to a support structure or a conductor structure. Publication FI201665157 considers only connection to the modular furniture part.
Summary of the invention
The invention relates to a new type of structural system which includes:
- an electrical device,
- a structural board, and
- attachment means for attaching the electrical device to the structural board.
Inside said structural board there are at least two conductor plates insulated from each other, said attachment means being arranged to connect the electrical device to at least two conductor plates of the structural board, and said electrical device having at least two attachment points for attachment means, each having an electrical coupling surface for connecting electricity from the attachment means to the electrical device.
The structural system according to the invention can be used, for example, for the implementation of furniture and/or parts of buildings. Said furniture may be, for example, furniture used in offices, apartments, hospitals, schools, production lines, assembly lines, and/or restaurants, and/or short-term furniture implementations, for example at trade fairs, or modifiable interior designs. Said parts of the buildings may be, for example, walls, ceilings, and/or floors.
The advantage of the structural system according to the invention is that the electrical device can be connected without separate and conventional coupling means, such as conductors and various connectors like spring, knife and screw connectors. Thus, the structure implemented with the structural system according to the invention is more compact and can be manufactured to a smaller size, and its installation is simpler and easier. Another advantage is that the manufacturing and installation costs of the electrical device may be lower than in the case where separate and conventional coupling means are used.
