Description

This invention relates to a table system for means of transport. In particular, the invention relates to a table system which can be advantageously applied in a railway carriage. Many means of transport, such as for example railway carriages or buses, currently have tables between the passenger seats designed to support small objects, such as mobile phones, tablets and portable computers, but also drinks, books, magazines or the like. A quite widespread seating configuration is that of having four seats in opposite pairs, that is to say, two facing the direction of travel and the other two facing in the opposite direction, with a table between them designed to support the above-mentioned items. Other configurations include tables, with a more limited size, facing only two passengers. According to prior art solutions there are tables having a supporting surface supported by a relative leg fixed on the floor and, if necessary, a further supporting bracket connected to a wall. The above-mentioned leg and, where present, the wall-mounted bracket, are designed to guarantee a stable support for the supporting surface of the table, which performs structural functions. This circumstance, that is to say, the fact that the supporting surface is also required to carry out main structural functions, relative to the retaining of the table in its entirety, means that the constraints imposed on designers in the design of new interior furnishings for railway carriages or means of transport in general are high. In other words, since the supporting surface of the table has to guarantee predetermined levels of mechanical performance and structural strength, these constraints often constitute exceptional limitations which are difficult to overcome by the designers. The aim of the invention is to provide a table system which is able to overcome the drawbacks of the prior art and which is at the same time practical to install and simple and inexpensive to make. A further aim of the invention is to provide a table system for means of transport which offers great versatility and allows the adoption of many supporting surfaces . Another aim of the invention is to provide a table system which can guarantee that the loads applied are held stably avoiding unwanted bending of the supporting surface, and which at the same time has a reduced size. According to the invention, these aims and others are achieved by a table system for means of transport comprising the technical features described in the accompanying claims. The technical features of the invention, with reference to the above-mentioned aims, are clearly described in the appended claims and its advantages are apparent from the detailed description which follows, with reference to the accompanying drawings which illustrate non limiting example embodiments of the invention, in which: - Figure 1 shows a schematic perspective view from above of a table system for means of transport according to the invention, - Figure 2 shows a schematic perspective view from above of the frame of the system of Figure 1, - Figure 3 shows a schematic perspective view from below of the frame of Figure 2, - Figure 4 shows a schematic front view of the frame of Figure 2, - Figure 5 shows a schematic view from below of the frame of Figure 2, - Figure 6 shows a schematic view from above of the frame of Figure 2 and - Figure 7 shows a schematic side view of the frame of Figure 2.
