Description

La présente invention vise une machine destinée au nettoyage des plages.The present invention relates to a machine intended for cleaning beaches.

On sait que le nettoyage des plages pose aux municipalités de gros problèmes, surtout si celles-ci ont des dimensions importantes.We know that beach cleaning poses major problems for municipalities, especially if they are large.

Jusqu'ici, on s'est généralement contenté d'em­ployer du personnel qui ramasse les détritus laissés par les vacanciers et ceux amenés par la mer. Ceci est très onéreux et lent. On a également proposé des appareils traî­nés par des tracteurs pour effectuer ce travail, mais ceux-­ci se sont revélés peu efficaces.So far, we have generally been content to employ staff who pick up litter left by vacationers and those brought by the sea. This is very expensive and slow. Apparatus dragged by tractors has also been proposed to do this work, but these have been shown to be ineffective.

On a également proposé des machines pourvues à l'avant d'un pick-up destiné à ramasser les détritus et à les déverser dans une goulotte les acheminant sur un tapis transporteur les déversant dans une benne. Une telle machine s'est avérée efficace, mais après de nombreux essais a montré quelques inconvénients ; notamment la machine enlève parfaitement les objets sur le sol, mais laisse ceux qui sont légèrement enfouis, de plus, elle ramasse une quantité relativement importante de sable de sorte que la benne est rapidement remplie du sable qui aurait dû normalement rester sur la plage, ce qui alourdit ladite benne inutilement.We have also proposed machines provided at the front with a pick-up intended to pick up the trash and dump it in a chute carrying them on a conveyor belt discharging them into a bucket. Such a machine has proven to be effective, but after many tests has shown some disadvantages; in particular the machine removes objects perfectly from the ground, but leaves those which are slightly buried, in addition, it collects a relatively large amount of sand so that the bucket is quickly filled with sand which would normally have remained on the beach, this which unnecessarily weighs down the bucket.

L'un des buts de la présente invention est de réaliser une machine automotrice efficace et qui ne pré­sente pas les divers inconvénients ci-dessus énoncés.One of the aims of the present invention is to provide an efficient self-propelled machine which does not have the various drawbacks mentioned above.

La machine, selon l'invention est du type com­prenant un engin automoteur supportant une benne basculan­te et avec à l'avant des moyens pour ramasser des détritus sur le sable et un tapis transporteur pour acheminer les détritus ramassés dans la benne et est caractérisée en ce que les moyens pour ramasser ces détritus sur le sable com­prennent un tablier monté pivotant sur un axe perpendicu­laire à l'axe longitudinal de l'engin, des moyens étant prévus pour commander le réglage de l'inclinaison dudit tablier, ce dernier comportant à son extrémité antérieure une lame destinée à s'engager dans le sol et en arrière de celle-ci un transporteur à grilles débouchant sur le tapis transporteur et entraîné par des moyens moteurs.The machine according to the invention is of the type comprising a self-propelled machine supporting a tilting bucket and with means at the front for collecting litter from the sand and a conveyor belt for transporting the litter collected in the bucket and is characterized in that that the means for picking up this detritus on the sand comprise an apron mounted to pivot on an axis perpendicular to the longitudinal axis of the machine, means being provided for controlling the adjustment of the inclination of said apron, the latter comprising at its end previous a blade intended to engage in the ground and behind the latter a grid conveyor opening onto the conveyor belt and driven by motor means.

Grâce à cette disposition la machine ramasse même les objets enfouis et le sable est rejeté.Thanks to this arrangement, the machine even collects buried objects and the sand is thrown away.

Afin de bien débarrasser du sable les objets ramassés, le transporteur à grilles comporte des moyens de secouage.In order to properly dispose of the collected objects from the sand, the grid conveyor includes shaking means.

Suivant une caractéristique constructive, le transporteur à grilles est formé d'une série de barreaux parallèles reliés par un lien souple.According to a constructive characteristic, the grid conveyor is formed by a series of parallel bars connected by a flexible link.

Suivant encore une caractéristique construc­tive, le transporteur à grilles comporte des pignons de forme générale triangulaire coopérant avec les barreaux et disposés au voisinage des côtés de celui-ci. On réa­lise ainsi un moyen simple et très efficace pour engendrer le secouage.According to yet another constructive characteristic, the grid conveyor comprises gears of generally triangular shape cooperating with the bars and arranged in the vicinity of the sides thereof. We thus realize a simple and very effective means to generate shaking.

De préférence, le tablier est supporté par des patins réglables en hauteur.Preferably, the deck is supported by height-adjustable pads.

Afin d'éviter que la machine risque d'être en­dommagée si la lame rencontre un rocher, ce qui est fréquent sur les plages, ladite machine comporte des organes palpeurs situés en avant de la lame et reliés à des moyens de signa­lisation.In order to avoid the risk of the machine being damaged if the blade encounters a rock, which is common on beaches, said machine includes feeler members located in front of the blade and connected to signaling means.

Pour faciliter l'entraînement des détritus sur le tablier et augmenter le désablage de ces objets, la ma­chine comporte des tourniquets s'étendant au-dessus du trans­porteur à grilles et entraînés en rotation dans un sens opposé à celui du défilement du transporteur.To facilitate the entrainment of litter on the apron and to increase the desanding of these objects, the machine comprises turnstiles extending above the grid conveyor and driven in rotation in a direction opposite to that of the conveyor run.

Suivant un détail constructif, les tourniquets comportent à leurs extrémités libres des languettes souples et élastiques, de telles languettes sont pratiquement effi­caces notamment pour désabler des algues, du goémon etc..According to a constructive detail, the turnstiles have flexible and elastic tongues at their free ends, such tongues are practically effective in particular for removing algae, seaweed, etc.

Suivant une caractéristique constructive, la machine comporte deux tapis transporteurs s'étendant sensi­ blement horizontalement et situés l'un dans le prolongement de l'autre à l'avant de l'engin entre le tablier et le ta­pis transporteur amenant les détritus dans la benne, lesdits deux tapis transporteurs étant entraînés de manière à faire converger les objets qu'ils transportent.According to a constructive characteristic, the machine comprises two conveyor belts extending sensi horizontally horizontally and located one in the extension of the other at the front of the machine between the deck and the conveyor belt bringing the detritus into the bucket, said two conveyor belts being driven so as to converge the objects that 'they carry.

Suivant encore une caractéristique constructive, la machine comporte des vérins insérés entre le châssis et le tablier pour commander le relevage de celui-ci.According to yet another constructive characteristic, the machine comprises jacks inserted between the chassis and the deck to control the lifting thereof.

La machine peut comporter à l'arrière un rateau afin d'égaliser la surface qui a été remuée par le tablier.The machine may include a rake at the rear in order to equalize the surface which has been moved by the apron.

La machine peut également comporter un réservoir destiné à contenir un produit désinfectant et une rampe de pulvérisation disposée à l'arrière et reliée au réservoir.The machine can also include a reservoir intended to contain a disinfectant product and a spraying boom arranged at the rear and connected to the reservoir.

Pour faciliter l'enlèvement de détritus pesants, la machine peut comporter au-dessus du transporteur à gril­les un second transporteur à grilles monté basculant par son extrémité supérieure sur un axe perpendiculaire à la direction d'avancement de la machine et dont l'extrémité inférieure située au-dessus de la lame repose sur des butées prévues sur celle-ci, le second transporteur étant entraîné par un moteur dans un sens de rotation opposé à celui du transporteur à grilles du tablier. Ainsi, ces détritus se trouvent pincés entre les deux transporteurs à grilles et acheminés vers le tapis transporteur. Si l'objet ramassé a des dimensions supérieures à l'intervalle entre la lame et le second transporteur à grilles, ce second transporteur se soulève ce qui élimine les risques de détériorations de ce dernier.To facilitate the removal of heavy detritus, the machine can comprise, above the grid conveyor, a second grid conveyor mounted tilting by its upper end on an axis perpendicular to the direction of advance of the machine and whose lower end located above the blade rests on stops provided on the latter, the second conveyor being driven by a motor in a direction of rotation opposite to that of the apron grid conveyor. Thus, this trash is pinched between the two grid conveyors and routed to the conveyor belt. If the object picked up has dimensions greater than the interval between the blade and the second grid conveyor, this second conveyor is raised, which eliminates the risk of damage to the latter.

Pour augmenter l'efficacité de la machine, une partie des barreaux constituant le second transporteur à grilles comporte des profilés souples et élastiques.To increase the efficiency of the machine, part of the bars constituting the second grid conveyor comprises flexible and elastic profiles.

Dans certains cas, la machine doit pouvoir éli­miner des détritus très petits qui risquent de passer entre les barreaux du transporteur à grilles. Pour permettre le ramassage de ces petits détritus, la machine peut comporter monté directement sur le transporteur à grilles du tablier un grillage.In some cases, the machine must be able to remove very small detritus which may pass between the bars of the grid conveyor. To allow the collection of these small detritus, the machine may have mounted directly on the apron grate conveyor.

Le châssis 1 est solidaire à l'avant d'un bâti 15 qui supporte deux tapis transporteurs 16 et 17, ceux-­ci étant entraînés de manière à converger vers un tapis transporteur 18 débouchant dans la benne 7.The chassis 1 is secured to the front of a frame 15 which supports two conveyor belts 16 and 17, these being driven so as to converge towards a conveyor belt 18 opening into the bucket 7.

Sur l'arbre 20 du moteur 2 est calée une pou­lie 21 qui entraîne par une courroie 40 une poulie 23 ca­ lée sur un arbre 22. Sur ce dernier sont calés des pignons 24 et 31, le pignon 24 entraînant par une chaîne 25 un pi­gnon 26 d'un boîtier 41 de renvoi d'angles, ledit boîtier comportant une première sortie sur laquelle est calé un pignon 27 qui entraîne par une chaîne 29 un pignon 30 calé sur un rouleau 42 sur lequel est guidé le tapis transpor­teur 16, celui-ci étant également guidé sur un rouleau 43 monté fou sur le bâti 15.On the shaft 20 of the motor 2 is wedged a pulley 21 which drives by a belt 40 a pulley 23 ca lée on a shaft 22. On the latter are pinions 24 and 31, the pinion 24 driving by a chain 25 a pinion 26 of a gearbox 41 of angular return, said housing having a first outlet on which is wedged a pinion 27 which drives by a chain 29 a pinion 30 wedged on a roller 42 on which the conveyor belt 16 is guided, the latter also being guided on a roller 43 mounted idly on the frame 15.

Le tapis transporteur 17 est guidé sur deux rouleaux 45 et 46 supportés par le bâti 15, le rouleau 46 étant solidaire d'un axe 38 sur lequel est calé un pignon 37 coopérant avec une chaîne 36 entraînée par un pignon 35 de sortie d'un boîtier 34 de renvoi d'angles, le pignon d'entrée 33 étant relié par une chaîne 32 au pignon 31. Grâce à cette disposition les tapis transporteurs 16 et 17 sont entraînés pour défiler dans le sens des flèches (figure 1).The conveyor belt 17 is guided on two rollers 45 and 46 supported by the frame 15, the roller 46 being integral with an axis 38 on which a pinion 37 is wedged cooperating with a chain 36 driven by a pinion 35 output from a housing 34 for returning the angles, the input pinion 33 being connected by a chain 32 to the pinion 31. Thanks to this arrangement, the conveyor belts 16 and 17 are driven to scroll in the direction of the arrows (FIG. 1).

Sur l'arbre 22 est calé un pignon 48 qui entraî­ne une chaîne 49 entraînant un pignon 50 calé sur un rou­leau 51 d'entraînement du tapis transporteur 18.On the shaft 22 is wedged a pinion 48 which drives a chain 49 driving a pinion 50 wedged on a roller 51 for driving the conveyor belt 18.

Le bâti 15 supporte également un tablier 60 formé par un cadre de forme générale rectangulaire avec deux côtés 61 et 62 deux traverses 63 et 64 et un côté in­termédiaire 65.The frame 15 also supports an apron 60 formed by a generally rectangular frame with two sides 61 and 62 two cross members 63 and 64 and an intermediate side 65.

Les côtés 61 et 62 sont reliés par un axe moteur 67 sur lequel est calé un pignon 70 coopérant avec une chaî­ne 71 engrenant avec un pignon 72 calé sur un arbre 73 sur lequel est calé un pignon 74 entraîné par une chaîne 75 en prise avec un pignon 76 d'une seconde sortie du boîtier 41.The sides 61 and 62 are connected by a motor shaft 67 on which is pinched a pinion 70 cooperating with a chain 71 meshing with a pinion 72 propped up on a shaft 73 on which is pinned a pinion 74 driven by a chain 75 engaged with a pinion 76 of a second outlet from the housing 41.

Sur l'arbre 67 sont calés quatre pignons 78 et, sur un axe 80 reliant les côtés 61 et 62, à leur extré­mité inférieure, sont montés fous des pignons 79.On the shaft 67 are wedged four pinions 78 and, on an axis 80 connecting the sides 61 and 62, at their lower end, are mounted idler pinions 79.

Sur les deux pignons 78 situés entre le côté 61 et la traverse 65 et les deux pignons 79 correspondants, est guidé un transporteur à grilles 81. Un transporteur identique 81 est guidé entre le côté 62 et la traverse 65 sur les pignons 79 et 78.On the two pinions 78 located between the side 61 and the crosspiece 65 and the two corresponding pinions 79, a grid conveyor 81 is guided. An identical conveyor 81 is guided between the side 62 and the crosspiece 65 on the pinions 79 and 78.

Les deux transporteurs 81 sont formés par des barreaux 82 s'étendant parallèlement et reliés par un lien souple ou des maillons 84. A des intervalles réguliers les barreaux sont solidaires de profilés en L 83.The two conveyors 81 are formed by bars 82 extending in parallel and connected by a flexible link or links 84. At regular intervals the bars are integral with L-shaped profiles 83.

Sur les côtés 61 et 62 et sur le côté intermé­diaire 65 sont montés fous des pignons 85 qui affectent la forme générale d'un triangle équilatéral, les dents étant destinées à coopérer avec les barreaux 82.On the sides 61 and 62 and on the intermediate side 65 are mounted idler gears 85 which have the general shape of an equilateral triangle, the teeth being intended to cooperate with the bars 82.

L'arbre 67 est guidé dans des paliers 88 du bâti 15 et entre les côtés 61 et 62 sont insérés des vérins 90 qui permettent de faire basculer le tablier 60 autour de l'axe 67 de manière à pouvoir, à volonté, abaisser ou relever ledit tablier 60.The shaft 67 is guided in bearings 88 of the frame 15 and between the sides 61 and 62 are inserted jacks 90 which make it possible to tilt the deck 60 around the axis 67 so as to be able to lower or raise it at will. said apron 60.

A leur extrémité inférieure, les côtés 61 et 62 sont solidaires de patins 92 supportés de préférence par des vérins 93.At their lower end, the sides 61 and 62 are integral with pads 92 preferably supported by jacks 93.

A son extrémité inférieure le tablier 60 est solidaire d'une lame 95, tandis qu'en avant de cette lame s'étendent des palpeurs 96 portés par une barre 97 suppor­tée par ledit tablier.At its lower end, the apron 60 is integral with a blade 95, while in front of this blade extend feelers 96 carried by a bar 97 supported by said apron.

Les palpeurs 96 sont constitués ici par des barres élastiques qui sont reliées à un organe de signali­sation si au cours du travail de la machine elles ploient au-delà d'une certaine position. Ces palpeurs 96 permettent, par conséquent, de détecter des rochers afin d'éviter que la lame 95 rencontre ceux-ci ce qui risquerait d'endommager la machine.The feelers 96 are constituted here by elastic bars which are connected to a signaling member if during the work of the machine they bend beyond a certain position. These feelers 96 therefore make it possible to detect rocks in order to prevent the blade 95 from encountering them, which would risk damaging the machine.

Le système de signalisation peut être visuel, acoustique ou directement relié à la machine afin de blo­quer celle-ci. On pourrait également prévoir que ledit sys­tème agit directement sur les vérins 90 et commande le re­levage instantané du tablier 60 si un rocher est détecté par les palpeurs 96. Le système de signalisation n'est pas représenté ici en détail.The signaling system can be visual, acoustic or directly connected to the machine in order to block it. It could also be provided that said system acts directly on the jacks 90 and controls the instantaneous lifting of the deck 60 if a rock is detected by the feelers 96. The signaling system is not shown here in detail.

Sur l'axe 67 est calée une poulie 100 qui entraî­ne par une courroie croisée 101 une poulie 102 calée sur un axe 103 guidé dans des paliers des côtés 61 et 62, ledit axe comportant à des intervalles réguliers des tourniquets 105 formés de bras radiaux 104 pourvus à leur extrémité libre de palettes 106 en matière souple et élastique, ces dernières venant affleurer les barreaux 82 des transporteurs 81.On the axis 67 is wedged a pulley 100 which drives by a crossed belt 101 a pulley 102 wedged on an axis 103 guided in bearings on the sides 61 and 62, said axis comprising at regular intervals turnstiles 105 formed by radial arms 104 provided at their free end with pallets 106 made of flexible and elastic material, the latter coming flush with the bars 82 of the conveyors 81.

La machine, selon l'invention est, plus particu­lièrement destinée au nettoyage des plages. La machine se déplace sur la plage à nettoyer, la lame étant enfoncée dans le sable à une certaine profondeur réglée par les patins 92 et les vérins 90. Le sable arrive sur les transporteurs 81 qui sont entraînés par les pignons 78, le sable retombe à travers les intervalles des barreaux 82, tandis que les détritus algues et autres sont entraînés par les profilés 83. Les tourniquets 105, par les palettes 106 frappent les­dits détritus pour les débarrasser du sable qui y adhère et cette action est renforcée par le secouage des transpor­teurs 81, secouage engendré par les pignons 95 dont les dents en coopérant avec les barreaux 82 tendent à soulever et à abaisser lesdits barreaux 82.The machine according to the invention is more particularly intended for cleaning beaches. The machine moves on the beach to be cleaned, the blade being driven into the sand at a certain depth regulated by the pads 92 and the jacks 90. The sand arrives on the conveyors 81 which are driven by the pinions 78, the sand falls back to through the intervals of the bars 82, while the algae and other detritus are entrained by the sections 83. The turnstiles 105, by the pallets 106 strike said detritus to rid them of the sand which adheres to it and this action is reinforced by the shaking of the carriers 81, shaking generated by the pinions 95, the teeth of which cooperating with the bars 82 tend to raise and lower said bars 82.

Si les palpeurs 96 rencontrent une résistance anormale dans le sol, il est émis un signal permettant au conducteur d'arrêter la machine et d'éviter ainsi d'endom­mager cette dernière.If the probes 96 encounter an abnormal resistance in the ground, a signal is sent allowing the driver to stop the machine and thus avoid damaging the latter.

Les détritus entraînés par les transporteurs 81 tombent sur les tapis 16 et 17 qui les entraînent vers le transporteur 18, ce dernier les déversant dans la benne 7.The detritus entrained by the conveyors 81 falls on the belts 16 and 17 which entrain them towards the conveyor 18, the latter discharging them into the bucket 7.

Le rateau 10 permet de niveler le sol, tandis que la rampe peut pulvériser un liquide désinfectant ou autre, celui-ci étant contenu dans le réservoir 13.The rake 10 makes it possible to level the ground, while the ramp can spray a disinfectant or other liquid, this being contained in the reservoir 13.

Lorsque la benne 7 est pleine, le tablier 60 est relevé et la machine est conduite à une décharge où la benne est vidée.When the bucket 7 is full, the apron 60 is raised and the machine is taken to a landfill where the bucket is emptied.

On peut prévoir, comme représenté aux figures 6 et 7,de supprimer les tourniquets 105 et de les rempla­cer par un second transporteur à grilles 131 qui permet d'enlever sur les plages des détritus lourds et ayant des volumes relativement importants.It is possible, as shown in FIGS. 6 and 7, to remove the turnstiles 105 and replace them with a second conveyor with grids 131 which makes it possible to remove on the beaches heavy detritus and having relatively large volumes.

Dans cette variante, les côtés 61 et 62 compor­tent chacun, en un point intermédiaire de leur longueur une patte 115 qui supporte un axe 116 solidaire d'un bâti com­prenant deux joues 117 et 118 reliées par deux arbres 119 et 120.In this variant, the sides 61 and 62 each have, at an intermediate point of their length, a tab 115 which supports an axis 116 secured to a frame comprising two cheeks 117 and 118 connected by two shafts 119 and 120.

Sur l'arbre 119 sont calés, à chaque extrémité des pignons 121, tandis que sur l'arbre 120 sont calés deux pignons 122. Sur l'arbre 120 est calé un pignon 125 qui coopère avec une chaîne 126 entraînée par un pignon 127 calé sur l'arbre de sortie d'un moteur 128 porté par un berceau 130 solidaire de la joue 118. Les pignons 121 et 122 présentent de larges dents pour entraîner un transpor­teur 131 formé de guilles 132 reliées entre elles par des bandes souples 133.On the shaft 119 are wedged, at each end of the pinions 121, while on the shaft 120 are wedged two pinions 122. On the shaft 120 is wedged a pinion 125 which cooperates with a chain 126 driven by a pinion 127 wedged on the output shaft of an engine 128 carried by a cradle 130 secured to the cheek 118. The pinions 121 and 122 have large teeth for driving a transporter 131 formed of guilles 132 connected together by flexible bands 133.

Les joues 117 et 118 au voisinage de leur extré­mité inférieure reposent sur des butées respectivement 135, 136 solidaires de l'extrémité supérieure de la lame 95.The cheeks 117 and 118 in the vicinity of their lower end rest on stops respectively 135, 136 secured to the upper end of the blade 95.

Certains barreaux 81 peuvent comporter des pro­filés 138 réalisés, par exemple, en une matière souple et élastique.Some bars 81 may include profiles 138 made, for example, of a flexible and elastic material.

Le moteur 128 entraîne le transporteur 131 à la même vitesse que celle du transporteur 81, mais dans le sens opposé (voir les flèches sur la figure 6). Ainsi, les détritus et objets plus lourds qui auraient tendance à glisser sur la lame 95 sont poussés par le transporteur 131 vers le transporteur 81. Si un objet trop important vient s'insérer entre la lame 95 et le transporteur 131 celui-ci bascule autour de l'axe 116 de sorte qu'on évite ainsi tout blocage de la machine et une possible détériora­tion des transporteurs à grilles 131.The motor 128 drives the transporter 131 at the same speed as that of the transporter 81, but in the opposite direction (see the arrows in FIG. 6). Thus, the trash and heavier objects which would tend to slide on the blade 95 are pushed by the conveyor 131 towards the conveyor 81. If an object too important comes to be inserted between the blade 95 and the conveyor 131 this one rocks around of the axis 116 so that all blocking of the machine and possible deterioration of the grid conveyors 131 are thus avoided.

On peut prévoir inséré entre le côté 61 et la joue 117, un vérin 137 permettant de soulever le second transporteur à grilles 131 pour faciliter le dégagement, d'un détritus qui serait coincé entre les deux transporteurs à grilles 81 et 131.It is possible to provide inserted between the side 61 and the cheek 117, a jack 137 making it possible to lift the second grate conveyor 131 to facilitate the release of a trash which would be trapped between the two grate conveyors 81 and 131.

Dans certains cas, on peut avoir à nettoyer des plages qui sont recouvertes de détritus de petites di­mensions. Comme les grilles du transporteur 81 ménagent entre elles des intervalles importants, l'enlèvement de ces petits détritus est impossible.In some cases, it may be necessary to clean areas that are covered with litter of small dimensions. As the grids of the conveyor 81 provide large intervals between them, the removal of these small detritus is impossible.

Pour permettre un tel nettoyage, l'invention prévoit de réaliser le transporteur 81 en montant sur celui-­ci un grillage 143.To allow such cleaning, the invention provides for carrying the conveyor 81 by mounting a screen 143 thereon.

Afin que le transporteur puisse néanmoins fonc­tionner normalement, le grillage 143 est directement réali­sé sur les barres qui composent le transporteur comme cela se voit clairement à la figure 8 ; ledit grillage compre­nant un premier fil métallique 140 plié en zigzag, pour former des mailles, en passant sur deux barres adjacentes 142, 144, un second fil métallique 141 plié en zigzag sur deux barres adjacentes 144, 146, dont l'une 144 reçoit le fil 140, le fil 141 étant plié pour passer entre les bran­ches d'une pliure passant sur la barre 144 et ainsi de suite. Un tel montage permet d'avoir un transporteur souple.So that the conveyor can nevertheless operate normally, the grid 143 is directly produced on the bars which make up the conveyor as is clearly seen in FIG. 8; said mesh comprising a first metal wire 140 folded in a zigzag, to form meshes, passing over two adjacent bars 142, 144, a second metal wire 141 folded in a zigzag on two adjacent bars 144, 146, one of which receives the 144 wire 140, wire 141 being folded to pass between the branches of a fold passing over the bar 144 and so on. Such an arrangement makes it possible to have a flexible transporter.

Bien entendu, l'invention n'est pas limitée aux modes de réalisations qui viennent d'être décrits et représentés. On pourra y apporter de nombreuses modifications de détail sans sortir pour cela du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and shown. Many modifications of detail can be made without departing from the scope of the invention.
