Abstract
A device providing smooth, controlled movement of a support along any plane path or along a path which is inscribed on certain defined surfaces (e.g. cones, cylinders). The device consists of an adjustable telescoping pole arranged on a motor-driven dolly moving along a set path which may be defined by straight or curved rails. The pole supports an adjustable joint which holds a swivelling dollying device (patent application no. 91-08870, Paris, 15 July 1991) for moving the support along a rectilinear path. The movement of the motor-driven dolly is controlled by that of the support on the swivelling dollying device. The device is particularly suitable for photography, film-making and video filming. The support is provided with a lighting system, a filming apparatus or both.
Description
DOUBLE TRAVELLING ASSERVI DOUBLE TRAVELING SERVO
L'invention concerne un dispositif de double travelling asservi, c'est-à-dire un dispositif assurant le déplacement régulier et commandé d'un support, réglable selon deux degrés de liberté (grâce à une double rotule), le long d'une trajectoire plane d'orientation quelconque ou bien le long d'une trajectoire inscrite sur certaines surfaces réglées (cônes, cylindres).The invention relates to a double tracking traveling device, that is to say a device ensuring the regular and controlled movement of a support, adjustable according to two degrees of freedom (thanks to a double ball joint), along a flat trajectory of any orientation or along a trajectory inscribed on certain regulated surfaces (cones, cylinders).
Il est constitué d'un mât télescopique réglable monté sur un chariot motorisé. Le mât est surmonté d'une articulation réglable qui enserre un dispositif de travelling orientable autorisant le déplacement du support sur une trajectoire rectiligne (demande de brevet n° 91-08870, Paris, le 15 juillet 1991). Celui-ci est constitué de deux rails parallèles tête bêche maintenus écartés par des entretoises. Sur l'un des rails circule le support orientable susceptible de recevoir un éclairage ou bien un appareil de prises de vues. Sur l'autre rail, circule symétriquement un contrepoids. Ce double mouvement est assuré par un moteur doté de deux poulies monté sur l'une des entretoises, par deux systèmes de poulies montés aux extrémités des rails, et par un câble qui transmet le mouvement Un contrepoids fixe compense le poids du moteur. Le mouvement du support mobile est réglable en amplitude et en vitesse. L'entretoise centrale de ce travelling orientable est fixée au sommet du mât télescopique.It consists of an adjustable telescopic mast mounted on a motorized trolley. The mast is surmounted by an adjustable articulation which encloses an orientable traveling device authorizing the displacement of the support on a rectilinear trajectory (patent application n ° 91-08870, Paris, July 15, 1991). This consists of two parallel head to tail rails kept apart by spacers. On one of the rails circulates the orientable support capable of receiving lighting or else a camera. On the other rail, a counterweight flows symmetrically. This double movement is ensured by a motor fitted with two pulleys mounted on one of the spacers, by two pulley systems mounted at the ends of the rails, and by a cable which transmits the movement A fixed counterweight compensates for the weight of the motor. The movement of the mobile support is adjustable in amplitude and speed. The central spacer of this orientable tracking shot is fixed to the top of the telescopic mast.
Le dispositif de travelling orientable est caractérisé par la dissociation de quatre paramètres de réglages : [1] la hauteur du centre de la course rectiligne du support (mât télescopique). [2] l'azimut de la course rectiligne du support (serrage d'une articulation). [3] la vitesse du support (variateur). [4] la longueur de la course du support (pilotage).The adjustable tracking device is characterized by the dissociation of four adjustment parameters: [1] the height of the center of the rectilinear stroke of the support (telescopic mast). [2] the azimuth of the rectilinear stroke of the support (tightening of a joint). [3] the speed of the support (drive). [4] the length of the support stroke (piloting).
La dissociation provient de ce que le dispositif de travelling orientable est composé de deux éléments, un pied et un système orientable de déplacement du support, reliés par une articulation réglable et verrouillable qui autorise une rotation azimutale autour du point d'équilibre. Cet ensemble, dans des configurations courantes, est démontable et portable. Son montage s'opère alors au moyen de techniques de clamps et de fixations familières aux photographes.
L'extension de ce dispositif à celui de double travelling asservi consiste à en fixer le mât sur un chariot motorisé qui peu circuler soit à même le sol, soit sur des rails droits ou courbes. Trois nouveaux paramètres apparaissent dès lors : [5] la courbe suivie par le chariot motorisé (e.g. cheminement des rails). [6] la vitesse du chariot motorisé (variateur). [7] la course du chariot motorisé (pilotage).The dissociation comes from the fact that the orientable tracking device is composed of two elements, a foot and an orientable system for moving the support, connected by an adjustable and lockable articulation which allows an azimuthal rotation around the point of equilibrium. This set, in common configurations, is removable and portable. It is then edited using clamping techniques and fixings familiar to photographers. The extension of this device to that of controlled double tracking consists in fixing the mast on a motorized carriage which can circulate either on the ground or on straight or curved rails. Three new parameters therefore appear: [5] the curve followed by the motorized carriage (eg track routing). [6] the speed of the motorized carriage (variator). [7] the stroke of the motorized carriage (piloting).
L'asservissement consiste à rendre interdépendants le déplacement du support sur son rail orientable (paramètres [3] et [4]) et celui du chariot au sol (paramètres [6] et [7]) par une combinaison de moyens électromécaniques (relais), photo-électriques (cellules) ou électronique (programmation).Enslavement consists in making the movement of the support on its orientable rail (parameters [3] and [4]) and that of the carriage on the ground (parameters [6] and [7]) interdependent by a combination of electromechanical means (relays) , photoelectric (cells) or electronic (programming).
On peut par exemple, et cette configuration n'est pas limitative, disposer des relais qui limiteront la course linéaire du contrepoids sur son rail, et donc celle du support sur le sien. Ces relais actionnent le moteur du travelling orientable de telle sorte que le support circule sur son rail dans un sens, puis dans l'autre. Entre deux de ces déplacements, le chariot sur lequel l'ensemble du dispositif est fixé avance d'une longueur déterminée sur son cheminement au soL Les vitesses de déplacement du chariot au soL du support sur son rail, sont réglées au moyen de variateurs. Ainsi le support peut balayer par bande une portion, par exemple en forme de U, de la surface réglée engendrée par le déplacement du raiL La nature de la surface sur laquelle le support est effectivement déplacé dépend des paramètres [2] et [5]. Sa hauteur moyenne est gouvernée par le paramètre [1]. Si le cheminement suivi par le chariot motorisé est droit ([5] est alors une ligne droite), le support se déplace, avec régularité et précision, sur un plan dont l'inclinaison est gouvernée par l'azimut [2]. Si le chariot motorisé se déplace sur une courbe, et si la direction de déplacement du support est verticale, son mouvement s'inscrit sur un cylindre. Si, pour le même genre de déplacement du chariot motorisé, on incline le travelling orientable, le support se déplace sur un cône.One can for example, and this configuration is not limiting, have relays which will limit the linear travel of the counterweight on its rail, and therefore that of the support on its own. These relays activate the motor of the traveling tracking so that the support circulates on its rail in one direction, then in the other. Between two of these movements, the carriage on which the entire device is fixed advances by a determined length on its path to the ground. The speeds of movement of the carriage to the ground of the support on its rail are adjusted by means of variators. Thus the support can sweep by strip a portion, for example in the shape of a U, of the adjusted surface generated by the movement of the rail. The nature of the surface on which the support is effectively moved depends on the parameters [2] and [5]. Its average height is governed by parameter [1]. If the path followed by the motorized carriage is straight ([5] is then a straight line), the support moves, with regularity and precision, on a plane whose inclination is governed by the azimuth [2]. If the motorized carriage moves on a curve, and if the direction of movement of the support is vertical, its movement is registered on a cylinder. If, for the same kind of movement of the motorized carriage, the swiveling traveling tilt is tilted, the support moves on a cone.
Ce dispositif de double travelling asservi est particulièrement destiné à la photographie, la cinématographie ou la vidéo. Le support accueille alors un système
d'éclairage, un appareil de prise de vues, ou les deux C'est le cas, par exemple, pour la reproduction d'oeuvres d'art (tableaux, dessins, plans, cartes ou décors), ou de la plupart des surfaces murales planes ou courbes, ou bien encore de plafonds inclinés ou non.

The support then hosts a system lighting, a camera, or both This is the case, for example, for the reproduction of works of art (paintings, drawings, plans, maps or decorations), or most surfaces flat or curved murals, or even inclined ceilings or not.
