Abstract
Description
La présente invention a trait aux chariots destinés à supporter la caméra et I'opérateur pour les prises de vues mobiles, du genre de celles connues sous le nom de travelling" dans l'industrie cinématographique. The present invention relates to carts intended to support the camera and the operator for mobile shots, of the kind known as traveling "in the film industry.
On sait que pour ce type de prises de vues on a normalement recours à des supports mobiles très sophistiqués, susceptibles d'être manuellement déplacés soit sur rails, soit sur une surface lisse, suivant un tracé parfaitement précis, mais ces engins présentent un certain nombre d'inconvénients, tenant notamment à leur coût élevé, à leur encombrement et à leur poids important. Aussi utilise-t-on assez fréquemment des dispositifs simplifiés, constitués en fait par un simple plateau équipé de deux roulettes fixes et de deux roulettes orientables ; le poids très réduit d'un tel support facilite évidemment le transport et la manutention, mais un guidage précis devient très difficile, sinon impossible. We know that for this type of shooting we normally use very sophisticated mobile supports, capable of being manually moved either on rails or on a smooth surface, following a perfectly precise path, but these devices have a certain number disadvantages, notably due to their high cost, their size and their significant weight. Also do we use quite frequently simplified devices, consisting in fact of a simple tray equipped with two fixed casters and two swivel casters; the very reduced weight of such a support obviously facilitates transport and handling, but precise guidance becomes very difficult, if not impossible.
Les perfectionnements qui font ltobjet de la présente invention visent à permettre la réalisation d'un chariot qui, sans prétendre offrir tous les avantages des modèles sophistiqués classiques, permet une utilisation plus pratique et plus rationnelle que les plateaux à roulettes usuels, tout en s'apparentant à ces derniers en ce qui concerne le poids et le coût. The improvements which are the subject of the present invention aim to allow the production of a trolley which, without claiming to offer all the advantages of the conventional sophisticated models, allows a more practical and rational use than the usual roller trays, while being related to these in terms of weight and cost.
le chariot suivant l'invention est principalement remarquable en ce qu'il comprend un plateau supporté par au moins trois chapes porte-galets orientables, liées les unes aux autres par une chaine sans fin et agencées de manière à ce que la commande angulaire impartie à l'une quelconque d'entre elles soit transmise aux autres. the trolley according to the invention is mainly remarkable in that it comprises a plate supported by at least three orientable roller-bearing yokes, linked to each other by an endless chain and arranged so that the angular control imparted to any one of them is passed on to the others.
Conformément à un mode de mise en oeuvre préféré de la disposition qui précède, le plateau comprend un châssis rectangulaire ou carré aux quatre angles duquel sont fixés des manchons-supports dont chacun renferme à pivotement, de manière aisément démontable, une chape porte-galets pourvue d'une partie supérieure prévue accessible sur la face supérieure du plateau afin de recevoir un guidon amovible de manoeuvre. Sur chaque manchon fixe tourillonne une roue dentée réunie à la chape correspondante par un doigt vertical, les quatre roues étant liées par une chaine sans fin associée à au moins un tendeur. In accordance with a preferred embodiment of the above arrangement, the plate comprises a rectangular or square frame at the four angles of which are fixed support sleeves, each of which pivotally, in an easily removable manner, a roller carrier yoke provided an upper part provided accessible on the upper face of the plate in order to receive a removable handlebar for maneuvering. On each fixed sleeve, a toothed wheel is connected to the corresponding yoke by a vertical finger, the four wheels being linked by an endless chain associated with at least one tensioner.
Chaque chape est avantageusement équipée de deux galets à bandage disposés côte à côte, en ménageant entre eux un espace libre propre à former logement pour une partie d'un guide fixe posé sur le sol, Le chariot suivant l'invention est ainsi susceptible de coopérer avec des guides en forme de rails lorsqu'un déplacement sur une surface lisse ne peut convenir, mais l'on observera que le caractère amovible des chapes porte-galets permet, si nécessaire, d'équiper le chariot de chapes pourvues de roues à mentonnet de type classique. Each yoke is advantageously fitted with two bandage rollers arranged side by side, by leaving between them a free space suitable for forming a housing for part of a fixed guide placed on the ground. The trolley according to the invention is thus capable of cooperating with guides in the form of rails when movement on a smooth surface is not suitable, but it will be observed that the removable nature of the roller-bearing screeds makes it possible, if necessary, to equip the carriage with screeds provided with flanged wheels of classic type.
Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer
Fig. 1 est une vue schématique en perspective d'un chariot comportant application des perfectionnements suivant l'invention.The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing.
Fig. 1 is a schematic perspective view of a carriage comprising application of the improvements according to the invention.
Fig. 2 est une coupe verticale à plus grande échelle montrant l'agencement de l'une des chapes porte-galets. Fig. 2 is a vertical section on a larger scale showing the arrangement of one of the roller carrier yokes.
Le chariot représente en fig. 1 comprend un châssis formé par un cadre tubulaire 1 à profil rectangulaire, raidi par trois traverses 2. The carriage represents in fig. 1 comprises a frame formed by a tubular frame 1 with a rectangular profile, stiffened by three crosspieces 2.
Sur ces traverses 2 est fixé un plateau en bois 3, avantageusement recouvert d'un tapis caoutchouté 4.On these crosspieces 2 is fixed a wooden tray 3, advantageously covered with a rubberized mat 4.
Dans chacun des angles du châssis 1-2 ainsi agencé on a prévu un manchon fixe 5 à axe vertical, dont la retenue en place est assurée à l'aide de boulons 6 (fig. 2) intéressant une bride 5a solidaire du sommet du manchon 5 considéré et le cadre 1 ou l'une des deux entretoises latérales 2. Chaque manchon 5 renferme deux roulements superposés dans lesquels est engagée une tige cylindrique 7, maintenue axialement dans ledit manchon à l'aide d'une vis 8 pourvue d'un bouton moleté de manoeuvre, l'extrémité de cette vis coopérant avec une gorge de ladite tige 7. Cette derniere dépasse au-dessus du manchon 5 sour la forme d'un prolongement 7a à section carrée, qui traverse le plateau 3 pour être accessible sur la face supérieure libre du tapis caoutchouté 4.A l'oppose la base de chacune des tiges 7 porte, audessous du manchon 5, une chape 9 sur l'axe horizontal de laquelle sont montés deux galets 10 à bandage caoutchouté. In each of the angles of the chassis 1-2 thus arranged, a fixed sleeve 5 with a vertical axis is provided, the retention in place of which is ensured by means of bolts 6 (fig. 2) involving a flange 5a secured to the top of the sleeve 5 considered and the frame 1 or one of the two lateral spacers 2. Each sleeve 5 contains two superimposed bearings in which is engaged a cylindrical rod 7, held axially in said sleeve using a screw 8 provided with a knurled operating button, the end of this screw cooperating with a groove in said rod 7. The latter protrudes above the sleeve 5 in the form of an extension 7a of square section, which crosses the plate 3 to be accessible on the free upper face of the rubberized mat 4. Opposite the base of each of the rods 7 carries, below the sleeve 5, a yoke 9 on the horizontal axis of which are mounted two rollers 10 with rubberized bandage.
Au-dessus de la paroi transversale de chaque chape 9, le manchon 5 est équipé d'une roue dentée 11 retenue axialement entre deux circlips superposés. Chaque roue 11 est folle sur son manchon 5, mais elle est liée angulairement à la chape 9 de celui-ci par l'intermediaire d'un doigt vertical 12 qui traverse le fond supérieur de ladite chape pour se visser dans le moyeu de la roue envisagée. Les quatre roues dentées 11 sont réunies les unes aux autres par une chatne sans fin 13 dont les brins orientés perpendiculairement aux traverses 2 passent sur des pignons tendeurs 14 (fig. 1) ; chaque pignon 14 est porte par un bras en équerre 15 susceptible d'être réglé en position le long de la traverse centrale 2, comme illustré en fig. 1. Above the transverse wall of each yoke 9, the sleeve 5 is equipped with a toothed wheel 11 retained axially between two superimposed circlips. Each wheel 11 is mad on its sleeve 5, but it is angularly linked to the yoke 9 thereof by the intermediary of a vertical finger 12 which crosses the upper bottom of said yoke to be screwed into the hub of the wheel considered. The four toothed wheels 11 are joined to each other by an endless link 13 whose strands oriented perpendicularly to the crosspieces 2 pass over tensioning pinions 14 (FIG. 1); each pinion 14 is carried by an angle arm 15 capable of being adjusted in position along the central cross member 2, as illustrated in FIG. 1.
Au chariot ci-dessus décrit est associé un guidon indépendant de manoeuvre 16 à profil en T dont le montant comporte une base tubulaire 16a profilée de façon à venir coiffer l'un quelconque des quatre prolongements carrés 7a pour en assurer le pivotement. On conçoit dans ces conditions que c'est sur ce guidon 16, convenablement assujeti à l'une des chapes porte-galets 9, qu'on doit exercer un effort de poussée ou de traction en vue d'assurer le déplacement de l'ensemble du chariot ; la manoeuvre angulaire simultanée de ce guidon 16 permet d'orienter les chapes 9 qui pivotent toutes ensembles par suite de la liaison assurée par la chaine 13, cette orientation commune autorisant un déplacement parfaitement précis et régulier du chariot. The carriage described above is associated with an independent operating handlebar 16 with a T-shaped profile, the upright of which comprises a tubular base 16a profiled so as to cover any one of the four square extensions 7a to ensure pivoting. Under these conditions, it will be understood that it is on this handlebar 16, suitably subjected to one of the roller carrier yokes 9, that a pushing or pulling force must be exerted in order to ensure the displacement of the assembly. of the carriage; the simultaneous angular operation of this handlebar 16 makes it possible to orient the yokes 9 which pivot all together as a result of the connection provided by the chain 13, this common orientation allowing a perfectly precise and regular movement of the carriage.
En dépit de cette précision de déplacement, le chariot reste de construction simple et bon marché. On observera que le recours à des galets doubles 10 pour chacune des chapes orientables 9 permet, lorsque désiré, de faire évoluer le chariot sur des guides à section circulaire, du genre de celui représente en 17 sur le tracé en trait interrompu de fig. 2 ; par suite du caractère aisément amovible des chapes 9, les manchons 5 sont même susceptibles d'être équipés, en cas de besoin, de chapes pourvues de galets à mentonnet, propres à coopérer avec des guides à section circulaire ou en I. Despite this precision of movement, the carriage remains of simple and inexpensive construction. It will be observed that the use of double rollers 10 for each of the orientable yokes 9 makes it possible, when desired, to move the carriage on guides with circular section, of the kind shown in 17 on the broken line in FIG. 2; as a result of the easily removable nature of the yokes 9, the sleeves 5 are even capable of being equipped, if necessary, with yokes provided with rollers with a chin, suitable for cooperating with guides of circular or I-section.
I1 doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. On conçoit en particulier que le nombre des chapes porte-galets peut être limité à trois, notamment pour la réalisation de chariots à plateau triangulaire. It should moreover be understood that the above description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents. It will be appreciated in particular that the number of roller carrier yokes can be limited to three, in particular for the production of trolleys with a triangular plate.
