• These end tabs, present on each side are of two types: a forked end tab 24 for the end 3 and a double end tab 25 for 1 • end 4 facing each other of the common central joint 13.
• the double end tab 24 is formed by two elements 26 and 26a, at least one of which, but preferably both, have a substantially horizontal underside disposed opposite the support and support plate 20.

• the springs 32 and 33 of the suspension are guided by internal parts 34 and 35 along which they move in a compression-relaxation movement corresponding to their suspension work.
• the support and support plate 20 mounted as a friction support on the upper face of the base 18 provided with an intermediate support and friction piece 36.
• the support and support plate 20 can be made according to different technological variants for example in a composite structure formed of several superimposed plates, for example three as shown in the figures or any other constitution.
• the support and support plate 20 has on its upper face a friction-carrying zone 37 extending for example on either side and around the support 21 articulation carrier.
• This friction-carrying zone 37 is lined around the articulation support 21 but at a distance therefrom, from a friction insert 38 in one piece in the form of a frame or in several pieces on which each of the corresponding soles 39 and 40 with which the underside of elements 26 and 26a of the double end tab 25 are equipped respectively.

It embeds the friction-carrying zone 37 and is produced in the form of a solid plate or a coating, in a material with a high coefficient of friction making it possible to degrade a significant part of the mechanical energy during the work of 'support and displacement in sliding-friction of the sole 39 or 40 of each underside of the elements 26 and 26a composing the double end tab 25 and 1 * friction insert 38 of the bearing-friction zone 37 opposite.
• this articulation support 21 is shaped as a vertical stirrup and is in the form of a mechanical block formed for example of two flank pieces assembled by a pin 41 to the support and support plate 20
• the articulation support 21 has in its upper part a displacement housing 42 for the pivot axis 23 of the pivot articulation 22.
• This housing 42 is formed by a lower transverse cylindrical cavity extending upwards by two branches open or paired by a transverse safety link.
• the pivot axis 23 of the pivot joint 22 can move along this housing 42 between a high position and a low position and vice versa. On this pivot axis are mounted the lateral ends of the fork dropout 24.
• the displacement housing 42 presents for the displacement of the axis 23 of the pivot joint 22 a cross section of substantially oblong shape open upwards but preferably with an outlet locked by the transverse safety link, for example by transverse bolts (not shown).
• the vertical mobility of the pivot axis 23 of the pivot joint 22 between a low position and a high position along its displacement housing 42 represents the vertical clearance used as freedom of movement in conjunction with the floating mounting of the plate support and support 20 and the latitude of movement existing between the double end tab 25 and the support and support plate 20.
• This latitude of movement corresponds to the travel between the support and the raised position of the double end tab 25 as will be described below in the explanation of operation.
• Reverse mobility is also used, that is to say that of the articulation support 21 with respect to the pivot axis 23 which, in this case is fixed. Of course, all cases of combination of these mobilities are possible.
• this function it is possible to produce the support 21 for movable articulation with respect to the support and support plate 20 to obtain complete independence of movement between one and the other ends of the wagon structures.
• the articulation support 21 thus crosses the support and support plate 20 to directly exert its pushing force on and against the friction piece 36 of the suspension assembly 19 forming a reading stand.
• this support 21 articulation can be slidably mounted in a recess through the center of the support plate 20 and support (not shown). A movement guided by grooves, grooves or other means would allow proper operation and a correct presentation of support of the base of this support 21.
• the movement of the pivot axis 23 along its housing is no longer completely necessary because it is provided by the displacement of its support 21 hinge door.
• articulation support 21 is also movable relative to the support and support plate 20, but acts indirectly on the bookcase and this through this plate 20. In this case, it is possible to provide additional travel between the support 21 hinge door and the plate 20 by an interval before contact.
• the floating lateral supports In taxiing, according to the movements coming from a wagon structure or from the other or from one side or the other of the same wagon structure, the floating lateral supports will work by moving in one direction or another by example from bottom to top or vice versa. The extreme positions are shown in Figures 5 to 9.
• the support and support plate 20 rips by sliding friction on the intermediate support and friction part 36.
• the pivot axis 23 is provided to rotate in its housing during pitch tilting.
• the double support leg 25 can be pushed downwards and it is then the two elements 26 and 26a of the double support leg 25 which collapse the suspension assembly 19 by pressing their lining plates 39 and 40 on the friction-carrying zone 37.
• the suspension assembly 19 descends with the support 21 articulation carrier, leaving the pivot axis 23 in its position in its housing 42 thanks to freedom of movement along this oblong section housing. Any composition of the above movements is possible due to the absence of a functional mechanical connection between the legs 24 and 25.
• the general interest of the present invention lies in the presence of at least two deflections, one at the level of the articulation support 21 and the other between the end tab 24 and the support and support plate 20. during movements due to rolling.
• these deflections are not necessarily simultaneous. They offer in all cases of normal use of wagon structures during taxiing, an idle stroke making it possible to avoid the transmission of movements at the other end, knowing that in addition, these are damped by the springs of suspension assembly 19.
• a support and support plate 20 in frictional contact with the upper face or the lining of the base 18 has a hinge support 43 receiving a special hinge 44 for pivoting about a horizontal axis and vertical translation.
• a multidirectional articulation for example of the ball-and-socket type or equivalent shape, may also be suitable although, apart from clearance clearance, only the vertical translational and pivoting movements about a horizontal axis passing through the articulation are concerned.
• the end tabs are almost identical in shape for one of them 45 with two branches 46 and 47 corresponding to the double tab 25, but different at its end for the other end tab, namely the central end tab 48 which is engaged on the articulation 44.
• the central end tab 48 ends with an end looking downwards and having a cavity forming a housing 49 for the articulation 44.
• the latter relates to the articulation support 43 produced in the form of a block 50, for example parallelepiped.
• a receiving element 51 by straight example as shown in Figure 12 cooperating with a stud 52 fitted to the bottom of the housing 49 to form a safety assembly for the operation of the joint.
• This articulation support 43 produced in the form of the block 50 comprises on a part of its lateral surface a bearing lining 53 with a convex outer face.
• This bearing lining 53 is located during operation opposite a fur 54 attached to the lateral surface of the housing 49.
• This fur 54 has a flat outer face which reduces the surface in contact with the outer face of the lining 53.
• articulation support 43 is the support block 50 on the support and support plate 20.
• this articulation support integral with the plate 20 or mounted thereon may be otherwise connected or related to it.
• this articulation support can be mounted mobile relative to the plate 20.
• the mechanical means shown and used to form the articulation 44 carried by the articulation support 43 were chosen because of the small amplitudes of movement generated during operation.
• the double end tab 45 acts by sliding support in the same way as that of the first variant.
• the central end tab 48 directly transmits the movement which animates it to the articulation 44. This makes it possible to absorb the types of deviations and displacements generated whether they are vertical, or inclination around of a horizontal pivot axis and of damping them by friction on the friction lining (s) and obtaining the uncoupling which is the main object of the invention.
