• the present invention relates to wagons for combined rail / road transport, also known as alternative transport, with a pivoting rail structure carrying the road load, regardless of the position of the pivot center on the wagon.
• This can indeed be central, end or intermediate.
• the general aim is to be able to carry out loading / unloading operations in a minimum of operating comfort and time by obliquely placing the carrying railway structure of sufficient amplitude.
• FIGS. 1 and 2 two basic general variants of the wagon according to the invention have been shown, differing only in the position of the pivot center of the carrying railway structure 6. These variants will be used for the following general description of the invention by its general means.
• the invention proceeds from the general idea inventive which consists, for a pivoting railway structure carrying the road load of a combined rail / road transport wagon, of disassembling the end platforms of the wagon by at least one of its ends while remaining mounted on its center pivoting to arrive after pivoting at an oblique position of loading / unloading the ends of this side completely detached from the end platform and then to find after reverse pivoting the integrity of the wagon after a quick, easy and safe assembly guaranteeing a connection rigid between the end platforms and the supporting railway structure.
• the typical wagon 1 comprises two end platforms 2 and 3 supported by one or more bogies or one or more axles 4 or 5. These end platforms 2 and 3 are connected together by a carrying railway structure 6 which is integral with these by its ends by means of rigid assembly links, these links being separable and lockable.
• the supporting railway structure 6 is a receptacle body formed by a low floor 7 in particular of thin thickness with a flat bottom 8 or otherwise shaped for example having a longitudinal housing 9 recessed in the form of a tunnel 10.
• the supporting railway structure 6 comprises in addition two protective side walls 11 and 12 for example of low height, delimited upwards by upper side members 13 and 14 extending beyond the body to end in ends such as 15, for example in the form of long arms, technically shaped so as to bear on and lock in complementary receiving conformations 16 provided in the receiving structure opposite the corresponding end platform or each end platform 2 or 3 in view to constitute the assembled state a separable link of rigid assembly through which all the traction forces and those coming from rolling movements pass.
• the wagon 1 in the closed state thus forms a solid and rigid mechanical assembly identical to a wagon in one piece.
• the wagon also has longitudinal lower edges 17 and 18, transverse end plates 19 and 20 and access spoilers 21 and 22.
• the floor 7 of the supporting structure 6 is thin and located as close as possible to the ground.
• this thin floor is shaped or constructed to form in the longitudinal central area where the road load does not carry, the recess 9 in the form of a tunnel 10 in which is housed a longitudinal connecting element 23 mechanically connecting the two end platforms 2 and 3 to guarantee that these platforms are kept in their original position during loading / unloading operations.
• This tunnel 10 brings a stiffening effect to the floor 7 and allows the routing of cables and fluidic conduits.
• the end platforms 2 and 3 may have on their face turned towards the interior of the wagon a return 24 directed downwards on the upper part of which is shaped a shoulder 25.
• the receiving structures 16 on which bear the ends 15 of the structure carrier rail 6 are shaped at the ends of this shoulder 25 opposite the ends of the carrier structure.
• the supporting railway structure 6 also comprises, on the underside of at least one of its access ends, means intended to cooperate with an external means of lifting and pivoting drive.
• wagon 1 has some means of retaining the end platforms in their original remote position
• a central pivot center 28 In the case of a load-bearing railway structure with two ends that can be separated from the end platforms, a central pivot center 28 will be preferred (FIG. 1).
• the variant with a central pivot center 28 will be described below because it has the most advantages.
• the lifting of dissociation or disassembly of the ends of the carrying railway structure is preferably carried out simultaneously at each of the ends by any suitable means, preferably external to the wagon, for example a device for lifting and pivoting drive, not shown, with lifting cylinders and rollers movable vertically and motorized to lift and then drive the supporting railway structure in pivoting towards the loading / unloading platform.
• this structure will have on the underside at the level of at least one or each of its ends a flat track 29 for support and rolling for example in an arc centered on the pivot center allowing the lifting and driving work by the motorized rollers of this device.
• the separable rigid assembly links between the ends of the supporting structure 6 and the end platforms 2 and 3 can be produced in different ways. Their general function is to allow the supporting railway structure 6 to be one with the end platforms 2 and 3 of the wagon so that all the traction forces and those linked to running pass through them. Thus, these separable links of rigid assembly must have high mechanical strength but also great security and reliability. An interlock is therefore provided to guarantee that the closed state is maintained during transport.
• ends 15 of the upper longitudinal members 13 and 14 of the carrying railway structure 6 are extremely short arms called ends which are formed into hook structures as well as those formed at the end of the lower longitudinal edges 17 and 18 of the wagon thus forming each time a short composite end 30 in double hook, the upper 31 and the lower 32.
• the upper hooks and their receiving structure support the vertical load and transmit the tensile forces while the lower hooks and their receiving structures are intended to overcome the tilting torque.
• Closing security is ensured by an automatic locking device 36 in the form of a curved locking finger 37 pivotally mounted and actuated in closing by a return spring 38 and tilted in opening by a motor mechanism not visible for example at compressed air available on the wagon.
• This automatic locking device 36 acts only on the upper hook.
• each upper hook of the support structure has a recess 39 delimiting a receptor space open at the front. This open receiving space is crossed in the middle part by a transverse rod on which the locking finger 37 comes to bear.
• the end platforms each have on the inside of the wagon the downward return 24 comprising one upper transverse shoulder 25 in each of the ends of which the complementary reception structures and conformations 33 are shaped in hooks.
• the wagon includes means for holding the end platforms in their absolute or relative original position.
• this is for example the longitudinal mechanical connection by the longitudinal connecting element 23 connecting together at a low level the two end platforms each supported by at least one rail bogie.
• This longitudinal connecting element 23 has no other main purpose than to mechanically connect the two end platforms 2 and 3 together so as to retain them in their initial position during the loading and unloading phases.
• the longitudinal connecting element can be made in thin thickness so as not to penalize the dimensions of the wagon and of the load relative to the railway gauge.
• this longitudinal connecting element remains projecting outside the floor 7.
• this longitudinal connecting element 23 tends to bend downwards in its central part 39. This bending causing an overtaking downwards which can put the assembly out of shape it is appropriate to recall this element 23 upwards in its central part 39, for example by a simple fixing or a connection in the lower central part of the carrying railway structure 6.
• This tunnel 10 also makes it possible to pass the pressurized fluid conduits and the electrical connection cables from one end platform 2 and 3 to the other.
• this tunnel 10 is formed in an area of the floor 7 which does not interfere with the loading.
• This longitudinal connecting element 23 fulfills its main function of retaining in position the end platforms 2 and 3 in their initial position during the loading / unloading maneuvers to ensure the speed and convenience of the rigid assembly between the plates end shapes and the composite ends 30 of the carrying railway structure in all the positions of the pivot center thereof.
• the invention is aimed not only at railway structures pivoting around their center but also around one of their ends or at any location.
• the longitudinal connecting element 23 fulfills a second technical function when the pivot axis is central. This is to support the pivot center. Therefore, for this type of variant, the central part 39 of this element becomes more complex.
• An example is shown in Figures 7 to 13, however, a central pivot 28 and a means to release the connecting element 23 are sufficient in the case of a tunnel 10.
• the central part 39 fulfills three functions simultaneously, namely that of securing the longitudinal connecting element 23 to the supporting railway structure 6, that of supporting the central pivot center 28 around which the supporting railway structure 6 and finally that with associated means of achieving the release of the longitudinal connecting element 23 from its housing 9 provided in the form of a tunnel 10 in the floor 7 of the supporting railway structure 6.
• the central part 39 of the longitudinal connecting element 23 is mounted suspended on the roof of the tunnel 10 from the floor of the carrying railway structure 6.

• This blade leaves a clearance space 44 located between the roof of the housing 9 in the tunnel 10 and the opposite face of said metallic suspension blade 41.
• This clearance space 44 is occupied by a release motor assembly 45 for example with pneumatic energy comprising a pair of pneumatic bellows 46 and 47 as shown in FIGS. 7 to 9.

• the structure of the longitudinal connecting element 23 is thin and various shapes of section are possible, from shapes with rectangular section 51 as shown in FIG. 6, to thin ribbed or folded shapes, some examples of which are shown in Figures 14 to 16.
• FIG. 14 The particular shape shown in Figure 14 will be preferred. It is a generally flat shape 52 whose longitudinal edges are shaped into hollow tubes 53 and 54, for example of circular section serving as a pipe for pressurized fluids either directly or as protective and passage spaces for electrical conduits or cables or others .
• the ends of the connecting element 23 can have a shape in two divergent branches, for example in Y for the passage of lifting and pivoting drive means mounted on the track.
• the opening of these end branches can vary up to a maximum opening according to which the ends of these branches come to bear on the lower adjacent ends of the sides of the end platforms 2 and 3 in order to cooperate with members of the separable link or of the fixing elements provided at this level.
• Many other embodiments are possible. They all come within the scope of protection of the invention insofar as they fulfill the general function of retaining the end platforms in position during the movements of the carrying railway structure during the loading and unloading phases.
• the wagon has at least one of its ends a predisposition to the retention of these platforms by an external means existing on the track or along it and integral with the ground.
• the wagon also has a predisposition to the action of an external device for lifting and pivoting drive in the form of the support and rolling track 29 present underneath at least one end of the carrying railway structure 6, a practical example of which is shown in FIG. 17.

Due to the pivoting nature of the movement of this support structure, the track 29 has a generally curved shape, for example in an arc, the center of which is that of the central pivot center or the like.
• Another predisposition of the wagon concerns the maintenance of the end platforms 2 and 3 in the longitudinal position but also and simultaneously in tilting after the lifting movement of the supporting structure.
