ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an electrical lead and, more particularly, to an electrical lead that is used for transmitting electrical energy in buildings.
2. Prior Art
Known leads include overland leads, cables, wiring, motor windings and connections consisting of simple straight wires. Where such simple wires are visibly laid, the mere sight of these is not aesthetically pleasing to a human observer. This applies above all in cultural circles in which aesthetic aspects and the harmony of the human spirit with its surroundings plays an important role in everyday life.
SUMMARY OF THE INVENTION
It is therefore the object of the invention to improve known electrical leads and lead systems, particularly in regard to their aesthetic effect.
According to the invention this object is achieved in that the electrical lead is formed of aesthetically pleasing electrically conducting sections that are connected to one another. These sections fulfill double function. On the one hand they conduct the electrical current and on the other hand they are pleasant to look at.
While known attempts seek to achieve an aesthetic improvement of electrical leads by way of coverings, the invention proceeds in the reverse way in that it actually directs the attention to the leads and surprisingly achieves the desired aesthetic effect by suitable shaping of the leads.
In order to attain an economic use of material in a preferred embodiment of the invention the electrically conducting sections are lined up or arranged in a chain. Thus with relatively little material large distances can be spanned. The invention however also encompasses arrangements that deviate from the chain arrangement, for example when a particular aesthetic effect is to be achieved.
In one embodiment of the invention the electrically conducting sections and/or chains consist of an electrically well conducting material, preferably copper, or of a material provided with an electrically conducting coating. For example, a whole chain may be formed as one piece from plastic and subsequently be coated or galvanized with a conducting paste.
In a preferred embodiment the electrically conducting sections are made from wire bent in the shape of outlines of one or more two-dimensional geometric figures such as squares, rectangles, triangles, circles, polygons, ellipses, arcs, spirals or stars. Such wire figures may be manufactured by machine in a simple manner and connected to one another, wherein a relatively large lead cross-section for conducting higher currents with a relatively low ohmic resistance is provided. With a suitably skilled selection and arrangement of the geometric figures these may continuously be bent from one or more endless wires so that neither the wires need to be cut nor do the sections need to be connected to one another.
In another embodiment of the invention the electrically conducting sections are one or more planar bodies in the form of two-dimensional geometric figures such as squares, rectangles, triangles, circles, polygons, ellipses, arcs, spirals or stars, which are made of sheet metal or electrically conducting foil. These planar bodies can be manufactured in a simple manner by cutting out and punching by machine, wherein preferably at the same time a continuous chain is formed. When visible surfaces of the figures are punched at the same time, even further ornaments may be impressed.
For a very special purpose a further embodiment form is recommended in which the electrically conducting sections are formed like outlines of one or several three-dimensional geometric figures such as cubes, parallelepipeds, tetrahedrons, pyramids, spirals or stars of wire. This embodiment is suitable particularly for leads hanging freely in space, for example for a hanging lamp, if the aesthetic effect is to be brought to the center of attention of the observer.
For increasing the aesthetic effect the geometric figures may be arranged interlaced in one another. As such furthermore the electrical conduction and the mechanical rigidity of the lead can be improved.
By lining up various geometric figures in a chain one obtains a larger number of possible combinations for a lead, so that a practically unlimited number of various ornaments is possible. This variety may be even further increased by lining up the same or various geometric figures of varying sizes in a chain.
