TELESCOPIC DEVICE AT A TRAIN SYSTEM

Abstract: The invention relates to an arrangement (1) for a train system (2) consisting of vehicles (3) capable of connection in a row, which exhibit lifting devices to permit them to be lifted between a lowered position enabling them to be driven under loading cassettes (4) functioning as load carriers and a raised position enabling the vehicles to be driven on a base (6) with the load (5) supported between designated loading locations on land or on a ship, in conjunction with which connecting devices (7) are so arranged as to connect the vehicles (3) together with one another in pairs. The aforementioned connecting devices are formed by telescopic bars (7), which are supported in such a way as to be capable of pivoting both vertically (8) and horizontally (9).

Description: TELESCOPIC DEVICE AT A TRAIN SYSTEM The present invention relates to an arrangement for a train system consisting of vehicles capable of connection m a row, which exhibit lifting devices to permit them to be lifted between a lowered position enabling them to be driven under loading cassettes functioning as load carriers and a raised position enabling the vehicles to be driven on a base with the load supported between designated loading locations on land or on a ship, m conjunction with which connecting devices are so arranged as to connect the vehicles together with one another m pairs. Load cassettes with the ability to support the desired load, as the need arises, are so arranged as to be transported between load storage locations on land and on board vessels with the help of vehicles exhibiting drive devices enabling them to be driven between desired locations with the load. For this purpose, the vehicles are connected together with rigid couplings, which means that the distance between the vehicles, and thus between the load cassettes and the load supported thereon, is considerable and of no benefit when the cassettes are lowered at the designated storage locations on board ships or m storage areas. It is, of course, necessary to have a certain distance between the vehicles, viewed m the longitudinal sense, m order for them to be capable of turning when they are being transported on land without making contact with one another at their corners, as they would otherwise have to exhibit a completely rounded rear and front part. The principal object of the present invention is thus, m the first instance, to solve the aforementioned problems efficiently and safely by simple means. The aforementioned object is achieved by means of an arrangement m accordance with the present invention, which is characterized essentially m that the aforementioned connecting devices are formed from telescopic bars that are pivotally mounted both vertically and horizontally, so that a certain distance is provided between the vehicles, viewed m the longitudinal sense, when the telescopic bars are m their extended position, so that the vehicles, when they are being transported on land, shall be capable of turning without making contact with one another at their corners, and so that a small distance is present between the vehicles, viewed m the longitudinal sense, when the telescopic bars are set to the retracted position, so that the vehicles, when set down at their storage locations, shall be capable of being packed closely together. The invention is described below as a preferred illustrative embodiment, m conjunction with whicn reference is made to the accompanying drawings, m which: Fig. 1 illustrates the invention schematically m its operating function m a train system, viewed from the side and from above; Fig. 1A illustrates the aforementioned tram set m the compacted position; Fig. IB illustrates wagon-connectmg devices included m the invention m different positions; Fig. 2 illustrates a loading and unloading ramp between the land and a ship for a tram system accordance with the invention; Fig. 3 illustrates a single wagon included m the aforementioned tra system and the various component parts included therein; and Fig. 4 illustrates further views of a wagon and its associated component parts viewed from different directions and m different positions. An arrangement 1 for a tram system 2 consisting of vehicles 3 capable of connection m a row, which exhibit lifting devices to permit them to be lifted between a lowered position enabling them to be driven under loading cassettes 4 so arranged as to function as load carriers for a load 5 thereon and a raised loading position. In the raised position, the vehicles 3 are so arranged as to be capable of being driven on the ground 6 or some other base with a load 5 supported on a subjacent cassette 4 between designated loading locations on land or on a ship. Connecting devices 7 are so arranged as to connect together the vehicles 3, which are self-propelled or are moved by a common traction vehicle, m pairs with one another. In accordance with the invention, the aforementioned connecting devices are formed by telescopic bars 7, which are supported m such a way as to be capable of pivoting both vertically 8 and horizontally 9 about connecting points 10, 11 on the vehicles 3. The aforementioned telescopic bars 7 are capable of being connected at their respective ends 7A, 7B to a wheel bogie 12 on the respective vehicle 3, which turn is supported m a pivotally mounted fashion about a vertical bearing shaft 13. In conjunction with this, the telescopic bars 7 are so arranged as to pivot together with the connectable wheel bogies 12 rigidly connected to them in the lateral sense. Each telescopic bar 7 is also detachably attachable to the associated wheel bogie 12, so that it can pivot vertically about it. The aforementioned telescopic bars 7 can also be driven jointly by a motor, e.g. by means of a fluid or some other appropriate drive means, to vary their effective length as required. All the telescopic bars 7 can be connected to a common drive arrangement order to set the telescopic bars 7 to a desired length, and to enable them to be locked so as to retain their set length. Manual length adjustment of the telescopic bars 7 is also possible. The telescopic bars 7 can also be pivotally mounted m any desired direction at all via ball couplings or other couplings which permit unrestricted pivoting of the telescopic bars 7. The function and nature of the invention should have emerged from the foregoing, and its unrestricted application should also have been appreciated. The invention is not, however, restricted to what is described and illustrated above, but may be varied within the scope of the Patent Claims.
