Definitions

• the invention is in the field of transport, and it relates to a container for the combined transport "rail-road" of goods.
• rail-road combined transport which consists of transporting goods alternately by road vehicle and by rail vehicle.
• a problem to be solved lies in the transshipment of the container.
• one which consists in providing the container with deployable crutches laterally, so that the container can rest on the ground, leaving a space under its base sufficient to allow easy passage of the vehicle platform. When the latter is placed under the container, the crutches are laterally retracted to limit the transverse size of the container. Note also that the crutches are also telescopic to allow the passage of the vehicle tray, then the deposition or lifting of the container.

• a disadvantage of this kind of container lies in the fact that the crutches are not fully retracted in the retracted position.
• a solution has been proposed by patent FR 2677623 (BULLE), which consists in not only deploying / retracting the crutches laterally, but also in tilting / folding them at the level of the base, in the manner of the containers with folding crutches, for example described by patents EP 0706912 (ACKERMANN-FRUEHAUF) and EP 0443456 (SCHULZ).
• the disadvantage of such a container comes from the necessary bracing of the crutches by means of a support leg.
• the legs are articulated in a ball joint at their respective ends on the base of the container and on their relative leg, so that the legs can tilt in a plane transverse to the container during the lateral deployment of the crutches.
• the general object of the invention is to provide a container for the combined "rail-road” transport of goods, the structure of which allows both lateral deployment of the crutches with a minimum transverse size of the container, to allow easy passage of the tray of a road or rail vehicle, and a storage of crutches at the base of the container when the latter is loaded on said tray.
• Another object of the invention is to provide a container of the aforementioned type, the structure of which allows automated operation of the means of mobility of the crutches and the locking of the container on the platform of the vehicle, such a container having to offer all the guarantees of security. .
• a container for the combined "rail-road" transport of goods is of the type of container intended to rest alternately on the platform of a road vehicle and / or on the platform of a rail vehicle.
• This container comprises a base equipped with retractable crutches between a rest position of the container on the ground, in which the crutches are deployed laterally and tilted towards the ground, and a container transport position, in which the crutches are retracted and folded down longitudinally at the level of the base.
• the container of the invention is mainly characterized in that, for each of the crutches, the means for tilting / folding thereof comprises a telescopic leg arranged in a longitudinal plane parallel to the general orientation of the container, said leg being articulated at its respective ends on the stand and on a rigid support structure, which can be deployed laterally concomitantly with the lateral deployment of the stand, thanks to which the bracing offered by the leg is not troublesome for the passage of the platform of the vehicle , and the overall size of the container in the rest position on the ground differs from the space available under the container, between the crutches, only in the thickness of the latter in the transverse direction.
• the telescopic leg may itself be constituted by an operating member with mechanical or hydraulic control of its extension, but that according to a form preferred embodiment, the leg is maneuverable by a telescopic arm, advantageously constituted by a jack, said first, which bears in an articulated manner both on the stand and on the telescopic leg, the retracted position of the arm and of the corresponding leg in the rest position of the container in which the crutches are deployed.
• the crutches are longitudinally oriented towards the ends of the container, so that in the container rest position, the crutches on the same side define a naturally undeformable parallelogram, due to the weight of the container which exerts vertical pressure and thanks to the passive resistance of the leg and arm.
• Said rigid structure is for example constituted by a plate with a substantially longitudinal extension. This plate is supported at its respective ends by the lateral deployment means (second cylinder, rotating ring, stops) of the stand and by a telescopic transverse support member supported by the base.
• the container being preferably equipped with telescopic crutches
• each of the crutches is equipped with hydraulic power members for respectively their lateral deployment / retraction (second cylinder), their deployment telescopic retraction / retraction (third cylinder), and their tilting / folding (first cylinder).
• Said hydraulic power units are supplied from a self-contained hydraulic power plant specific to the container.
• each of the crutches further constitutes a member for operating a member (rod) for securing the container to the platform of the vehicle.
• This securing member is provided with spontaneous holding means (spring) in the position for dissolving the container and the vehicle platform, so that the lateral deployment of the crutches spontaneously induces the separation of the container and the vehicle platform, and conversely, the retraction of the crutches spontaneously induces their joining together.
• spontaneous holding means spring
• the container can be loaded and unloaded safely by autonomous hydraulic power means from the simple command by a loading / unloading operator, and that said power means are only active during said loading / unloading operations, and are passive, that is to say free from any constraint, when the container rests both on its crutches and on the vehicle platform.

• the base 2 of a "rail-road” container is equipped with crutches, such as 4, deployable / retractable laterally and tiltable / foldable at the level of the base.
• crutches 4 and their means of mobility 6,8,10 in tilting / folding down are arranged, both in the container rest position on the ground and in the container transport position, in planes O 98/15475
• the space E comprised between the base 2 and the crutches 4 is completely empty of elements liable to hinder the passage of the carrier plate of a vehicle, and that the lateral dimensions L of the container differs from this space E only in the transverse thickness e of the crutches 4.
• Each stand 4 is equipped with a telescopic support leg 6 in the rest position of the container on the ground, and for maneuvering their tilting / folding.
• This leg 6 is articulated at its respective ends on the stand 4 and on a rigid plate 10 with longitudinal extension which can be deployed laterally concomitantly with the lateral deployment of the stand 4.
• the telescopic leg 6 is maneuverable by means of a hydraulic jack 8, called the first one, which is supported on the stand 4 and on the telescopic leg 6, the retracted rod rod and retracted positions of the leg corresponding to the tilted position ( fig.5,6,7) of the crutch 4, so that the leg 6 and the jack 8 offer passive resistance to the forces exerted on the crutch 4.
• a hydraulic jack 8 called the first one, which is supported on the stand 4 and on the telescopic leg 6, the retracted rod rod and retracted positions of the leg corresponding to the tilted position ( fig.5,6,7) of the crutch 4, so that the leg 6 and the jack 8 offer passive resistance to the forces exerted on the crutch 4.
• the crutches 4 on the same side are longitudinally oriented towards the ends of the container, so as to define a parallelogram R which is naturally non-deformable under the weight of the container.
• the stand 4 is secured to a tube 14 mounted to rotate and guided in translation on the base 2 of the container, the lateral deployment / retraction of the stand 4 results from a translational maneuver of the tube 14 by means of a second jack 16.
• the tilting / folding of the stand 4 results of a pivoting operation of the tube 14 thanks to the deployment of the telescopic leg 6 by means of the first jack 8.
• the stand 4 is itself telescopic and can be deployed / retracted by means of a third jack which it houses (not shown in the figures).
• the plate 10 is supported at its respective ends by a telescopic transverse support member 18 supported by the base on the one hand, and by the tube 14 on which the plate 10 is pivotally articulated by means of a ring 12 ( fig.12) to which it is integral and which is threaded at the end of the tube 14 on the other hand, to allow rotation of the tube 14 for the tilting / folding of the stand 4 without inducing a pivoting of the plate 10 .
• each of the stands also constitutes an operating member for a rod 22 for securing the container to the platform of the vehicle.
• This rod 22 is spontaneously held in the disengaging position (FIG. 12) by means of a return spring 24 bearing on the base 2 and on a shoulder 26 of the rod 22.
• the rods 22 are pushed to be introduced into a keeper 28 formed on the platform of the vehicle (dotted in the figures).
• This finger 30 is designed to be introduced into a housing 32 formed on the base 2, to prohibit the pivoting of the tube 14 in the retracted / folded position of the stand 4 under the effect of the weight of the latter, and thus constitute a member of O 98/15475
