Description
La présente invention concerne un dispositif de travelling orientable, c'est-à-dire un dispositif assurant le déplacement rectiligne régulier d'un support susceptible de recevoir, par exemple, un système d'éclairages ou bien un appareil de prises de vues. The present invention relates to an orientable tracking device, that is to say a device ensuring the regular rectilinear movement of a support capable of receiving, for example, a lighting system or else a camera.
La trajectoire du support, longue de plusieurs mètres, a pour particularité de suivre une orientation quelconque par rapport au soL Le dispositif est utile aux procédés photographiques ou cinématographiques qui nécessitent un tel déplacement éloigné du sol et selon une orientation réglable depuis l'horizontale jusqu'à la verticale.The trajectory of the support, several meters long, has the particularity of following any orientation relative to the ground. The device is useful for photographic or cinematographic processes which require such displacement far from the ground and according to an adjustable orientation from horizontal to vertically.
Si le travelling d'un appareil de prise de vue et de son opérateur est connue des hommes de métier, si il arrive qu'on utilise le déplacement d'une caméra fixée sur un automate, le dispositif de travelling orientable qui fait l'objet de cette invention a comme caractéristique sa simplicité de mise en oeuvre et, dans des configurations courantes, le fait d'être démontable et portable. Son montage s'opère alors au moyen de techniques de clamps et de fixations familières aux photographes. If the tracking shot of a camera and its operator is known to those skilled in the art, if it happens that the displacement of a camera fixed on an automaton is used, the orientable tracking device which is the subject of this invention has as a characteristic its simplicity of implementation and, in current configurations, the fact of being removable and portable. It is then edited using clamping techniques and fixtures familiar to photographers.
Le dispositif est caractérisé par la dissociation de quatre paramètres de réglages: - la hauteur du centre de la course rectiligne du support (mât télescopique). The device is characterized by the dissociation of four adjustment parameters: - the height of the center of the rectilinear stroke of the support (telescopic mast).
- l'azimut de la course rectiligne du support (serrage d'une articulation, e.g. un clamp).- the azimuth of the rectilinear stroke of the support (tightening of a joint, e.g. a clamp).
- la vitesse de la course du support (variateur).- the speed of the support stroke (variator).
- la longueur de la course du support (relais ou bien pilotage de la durée de la course).- the length of the support stroke (relay or control of the duration of the stroke).
Cette dissociation provient de ce que le dispositif 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. This dissociation comes from the fact that the device is composed of two elements, a foot and an adjustable system for moving the support, connected by an adjustable and lockable articulation which allows an azimuthal rotation.
Le pied est constitué d'un mât télescopique surmonté par l'articulation. I1 peut s'agir, dans une configuration non limitative caractérisée par une course du support d'environ 2 mètres, d'un pied utilisé généralement pour soutenir de gros projecteurs. The foot consists of a telescopic mast surmounted by the articulation. I1 can be, in a non-limiting configuration characterized by a support stroke of about 2 meters, of a foot generally used to support large projectors.
I1 est surmonté d'un clamp de gros modèle. Dans une configuration plus lourde, il peut s'agir d'un mât hydraulique surmonté d'une articulation mécanique doté des mêmes caractéristiques de rotation azimutale, de réglage et de verrouillage. It is surmounted by a large model clamp. In a heavier configuration, it can be a hydraulic mast surmounted by a mechanical articulation endowed with the same characteristics of azimuthal rotation, adjustment and locking.
Le système orientable de déplacement du support est constitué de deux rails maintenus écartés par des entretoises. L'une d'entre elles, centrale, est fixée sur l'articulation. Ce système orientable est caractérisé par la position de son centre de gravité, au centre de l'articulation qui le rattache au pied, sur l'axe de sa rotation azimutale. Les rails sont ainsi montés tête-bêche, l'un guidant la course du support, l'autre, celle de son contrepoids. Ces deux courses, symétriques par rapport au centre de gravité du système orientable, sont entraînée par un moteur doté de deux poulies et monté sur l'une des entretoises, un contrepoids fixe symétrique rétablissant l'équilibre.Deux systèmes de poulies, chacune à fixée sur l'une des entretoises situées aux deux extrémités des rails, assurent le cheminement du câble qui transmet le mouvement
Le mouvement du support est piloté selon deux paramètres : sa vitesse, qui dépend de celle de la rotation du moteur, et la longueur de sa course, limitée par un dispositif électromécanique (relais), photo-électrique (cellule) ou bien électronique (programmation).The adjustable support movement system consists of two rails held apart by spacers. One of them, central, is fixed on the joint. This orientable system is characterized by the position of its center of gravity, at the center of the joint which connects it to the foot, on the axis of its azimuthal rotation. The rails are thus mounted head to tail, one guiding the travel of the support, the other, that of its counterweight. These two races, symmetrical with respect to the center of gravity of the steerable system, are driven by a motor equipped with two pulleys and mounted on one of the spacers, a symmetrical fixed counterweight restoring balance. Two pulley systems, each fixed on one of the spacers located at the two ends of the rails, ensure the routing of the cable which transmits the movement
The movement of the support is controlled according to two parameters: its speed, which depends on that of the rotation of the motor, and the length of its stroke, limited by an electromechanical device (relay), photoelectric (cell) or electronic (programming ).
Le support circulant, selon la configuration demandée par l'utilisation, accueille l'objet déplacé directement ou bien par l'intermdiaire d'une double rotule qui permet d'orienter l'objet à volonté. The circulating support, according to the configuration requested by the use, receives the object moved directly or through a double ball joint which allows the object to be oriented at will.
L'ensemble du dispositif, dans son utilisation la plus fréquente, peut être démonté et remonté au moyen de systèmes de serrages usuels dans le domaine des accessoires de photographie ou de cinéma. I1 peut être transporté dans des boîtiers conçus à cet effet. The entire device, in its most frequent use, can be dismantled and reassembled by means of clamping systems customary in the field of photography or cinema accessories. It can be transported in boxes designed for this purpose.

En référence à ces dessins qui illustrent une configuration non limitative autorisant un déplacement du support (11) d'environ 2 mètres, le dispositif est constitué d'un pied fixe réglable (1) au sommet duquel est fixé un clamp (2). Ce clamp (2) enserre en son centre de gravité (10) un système de deux rails (3 et 4) maintenus séparées par des entretoises (5 à 9). Celles du bas, en arceau, autorisent une position verticale des rails. Sur l'un des rails (4) circule le support orientable (11), sur l'autre rail (3), le contrepoids mobile (12). Ces deux mouvements symétriques par rapport au centre (10) sont assurés d'une part par un même moteur doté de deux poulies (13) et monté sur l'une des entretoises et d'autre part par deux systèmes de poulies (14 et 15) montés aux extrémités des rails, le tout étant relié par un câble.Un contrepoids fixe (16) monté sur l'une des entretoises assure l'équilibre de l'ensemble orientable (3 à 16) autour du pivot (10). With reference to these drawings which illustrate a non-limiting configuration allowing the support (11) to be displaced by approximately 2 meters, the device consists of an adjustable fixed foot (1) at the top of which is fixed a clamp (2). This clamp (2) encloses in its center of gravity (10) a system of two rails (3 and 4) kept separated by spacers (5 to 9). Those at the bottom, in an arch, allow a vertical position of the rails. On one of the rails (4) circulates the orientable support (11), on the other rail (3), the mobile counterweight (12). These two symmetrical movements relative to the center (10) are provided on the one hand by the same motor provided with two pulleys (13) and mounted on one of the spacers and on the other hand by two pulley systems (14 and 15 ) mounted at the ends of the rails, all connected by a cable. A fixed counterweight (16) mounted on one of the spacers ensures the balance of the swiveling assembly (3 to 16) around the pivot (10).
Les rails (3) et (4) et les chariots sur lesquels sont fixés le support mobile (11) et son contrepoids (12) relèvent de la technologie des glissières linéaires de précision. The rails (3) and (4) and the carriages on which the mobile support (11) and its counterweight (12) are fixed are based on precision linear slide technology.
Les rails peuvent être creux pour réduire le poids du dispositif. Ils comportent, à leur base, des trous (18) régulièrement espacés pour la fixation des entretoises (5 à 9).The rails can be hollow to reduce the weight of the device. They have, at their base, regularly spaced holes (18) for fixing the spacers (5 to 9).
Les entretoises (5 et 6) de la partie supérieure du système orientable sont plates et percées de trous symétriques (19) pour leur fixation sur les rails au moyen d'un dispositif de serrage ad hoc, de trous symétriques (20) pour la fixation du moteur (13) ou du système de poulies (14), enfin d'un trou central (21) qui peut laisser passer l'axe (28) du moteur (13). The spacers (5 and 6) of the upper part of the swiveling system are flat and pierced with symmetrical holes (19) for fixing to the rails by means of an ad hoc clamping device, symmetrical holes (20) for fixing motor (13) or pulley system (14), finally a central hole (21) which can let pass the axis (28) of the motor (13).
Les entretoises (8 et 9) de la partie inférieure du système orientable sont en arceau de telle sorte que le mât (1) ne gène pas un montage vertical du système orientable. Ces entretoises sont percées de trous symétriques (19) pour leur fixation sur les rails au moyen d'un dispositif de serrage ad hoc, de trous symétriques (20) pour la fixation du contrepoids fixe (16) ou du système de poulies (15). The spacers (8 and 9) of the lower part of the swiveling system are in an arch so that the mast (1) does not interfere with a vertical mounting of the swiveling system. These spacers are pierced with symmetrical holes (19) for fixing them to the rails by means of an ad hoc clamping device, symmetrical holes (20) for fixing the fixed counterweight (16) or the pulley system (15) .
L'entretoise-axe (7) est constituée d'une partie centrale cylindrique et de deux extrémites plates. La partie cylindrique s'adapte à l'extrémité (2) du mât (1) de telle sorte que le centre de gravité de cette entretoise (10) coïncide avec celui du système mobile et avec l'axe de rotation azimutal de ce système. Les extrémités plates sont percées de trous symétriques (19) pour leur fixation sur les rails au moyen d'un dispositif de serrage ad hoc. The spacer-axis (7) consists of a cylindrical central part and two flat ends. The cylindrical part adapts to the end (2) of the mast (1) so that the center of gravity of this spacer (10) coincides with that of the mobile system and with the azimuth axis of rotation of this system. The flat ends are pierced with symmetrical holes (19) for fixing to the rails by means of an ad hoc clamping device.
Le système de poulies supérieur (14) est constitué d'une plaque en "T" qui est fixée grâce aux trous (20) sur l'entretoise (5). Dans le prolongement des rails (3) et (4) se trouvent, tête-bêche, deux poulies (23). Au centre de la partie la plus haute de la plaque, deux poulies (22), une sur chaque face, assurent le renvoi du câble vers le moteur (13). The upper pulley system (14) consists of a "T" plate which is fixed by means of the holes (20) on the spacer (5). In the extension of the rails (3) and (4) are located, head to tail, two pulleys (23). In the center of the highest part of the plate, two pulleys (22), one on each side, ensure the return of the cable to the motor (13).
Le système de poulies inférieur (15) est constitué d'une plaque en "T" prolongée par deux plaques perpendiculaires à l'une de ses extrémités. Il est fxé grâce aux trous (20) sur l'entretoise (9). Dans le prolongement des rails (3) et (4) se trouvent, selon des axes perpendiculaires, deux poulies, l'une (23) fixée sur l'extrémité non altérée du "T", l'autre (25) fxée sur un prolongement de l'autre extrémité. Une troisième poulie (24) assure la circulation du câble entre les deux précédentes. The lower pulley system (15) consists of a "T" plate extended by two plates perpendicular to one of its ends. It is fixed thanks to the holes (20) on the spacer (9). In the extension of the rails (3) and (4) are, along perpendicular axes, two pulleys, one (23) fixed on the unaltered end of the "T", the other (25) fixed on a extension of the other end. A third pulley (24) ensures the circulation of the cable between the previous two.
Le système d'entraînement est constitué d'un moteur (13) fixé sur l'entretoise (6) par les trous (20). L'axe (28) du moteur sort de chacune de ses deux faces. Du côté antérieur, une poulie (26) est fixée sur l'axe (28). Du côté postérieur, l'axe (28) traverse l'entretoise (6) par le trou (21), puis il accueille une poulie mobile (26). Une vis (27) assure le serrage de cette poulie postérieure mobile (26) sur l'axe (28). The drive system consists of a motor (13) fixed to the spacer (6) by the holes (20). The axis (28) of the motor exits from each of its two faces. On the front side, a pulley (26) is fixed on the axis (28). On the posterior side, the axis (28) crosses the spacer (6) through the hole (21), then it receives a movable pulley (26). A screw (27) tightens this movable rear pulley (26) on the axis (28).
Le système orientable est monté comme indiqué ci-dessus, les dispositifs de serrage (29 et 30) assurent le maintien des différents constituants. Sur la figure 9, des relais (31) sont disposés sur la course du contrepoids mobile (12) afin de piloter le fonctionnement du moteur (13). The swiveling system is mounted as indicated above, the clamping devices (29 and 30) maintain the various components. In FIG. 9, relays (31) are arranged on the stroke of the mobile counterweight (12) in order to control the operation of the motor (13).
Le câble qui assure le déplacement du support (11) sur le rail (4) et celui de son contrepoids (12) sur le rail (3) est enroulé sur une poulie (26) fixée sur l'axe antérieur du moteur (13). I1 passe sur une poulie (22) situé au milieu de la face antérieure du système de poulies supérieur (14), puis est réorienté par une poulie (23) vers le support coulissant (11). De ce support, le câble repart vers la poulie (25) fixée à l'extrémité antérieure du système de poulies inférieur (15). Par la poulie (24), il atteind la poulie (23) à l'aplomb du rail (3).Le câble remonte alors vers le contrepoids mobile (12), puis repart de celui-ci vers une poulie (23) situé sur la face postérieure du système de poulies supérieur (14). I1 passe enfin sur une poulie (22) située au milieu de la même face postérieure, pour rejoindre une poulie (26) montée sur l'axe postérieur du moteur (13). The cable which moves the support (11) on the rail (4) and that of its counterweight (12) on the rail (3) is wound on a pulley (26) fixed on the front axis of the motor (13) . I1 passes over a pulley (22) located in the middle of the front face of the upper pulley system (14), then is redirected by a pulley (23) towards the sliding support (11). From this support, the cable goes back to the pulley (25) fixed to the anterior end of the lower pulley system (15). Via the pulley (24), it reaches the pulley (23) directly above the rail (3). The cable then rises to the mobile counterweight (12), then departs from this towards a pulley (23) located on the rear face of the upper pulley system (14). I1 finally passes over a pulley (22) located in the middle of the same rear face, to join a pulley (26) mounted on the rear axis of the motor (13).
La mise en oeuvre de l'invention consiste dans en premier temps à monter l'ensemble du dispositif comme indiqué ci-dessus. La hauteur du centre de gravité (10) est ajustée par réglage du mât télescopique (1). L'inclinaison azimutale du système orientable est ajustée au moyen du dispositif de serrage (2) qui maintient l'entretoise-axe (7). On monte ensuite le câble conformément à ce qui précède, et on le tend par rotation de la poulie postérieure (26) sur l'axe (28). Une fois obtenue une tension convenable on sert la vis (27). On règle la vitesse de déplacement du support en ajustant la vitesse de rotation du moteur (13) au moyen d'un variateur situé dans le boîtier de commande (17).On règle la longueur de la course du support au moyen d'un pilote situé dans le boîtier (17). Celui-ci peut-être relié à des relais (31) actionnés par le déplacement du contrepoids mobile (12). The implementation of the invention consists first of all in mounting the entire device as indicated above. The height of the center of gravity (10) is adjusted by adjusting the telescopic mast (1). The azimuthal inclination of the orientable system is adjusted by means of the clamping device (2) which holds the spacer-axis (7). The cable is then mounted in accordance with the above, and it is stretched by rotation of the rear pulley (26) on the axis (28). Once a suitable tension is obtained, the screw (27) is used. The speed of movement of the support is adjusted by adjusting the speed of rotation of the motor (13) by means of a variator located in the control unit (17). The length of the travel of the support is adjusted by means of a pilot. located in the housing (17). This can be connected to relays (31) actuated by the movement of the mobile counterweight (12).
Dans une configuration assurant une course rectiligne du support d'environ 2 mètres centrée sur un point situé à 2,50 mètres du sol, l'ensemble du dispositif pèse environ 60 kg, y compris la masse de l'objet déplacé (supposée égale à 10 kg) et celle de son contrepoids. Les rails, éventuellement creux, pèsent environ 12 kg (3 kg/m). In a configuration ensuring a rectilinear stroke of the support of approximately 2 meters centered on a point located 2.50 meters from the ground, the entire device weighs approximately 60 kg, including the mass of the object moved (assumed to be equal to 10 kg) and that of its counterweight. The rails, possibly hollow, weigh approximately 12 kg (3 kg / m).
Dans son montage, comme dans l'ajustement des réglages, il est conforme aux habitudes de travail des photographes professionnels. En pièces détachées, le dispositif est aisément transportable.In its editing, as in adjusting the settings, it conforms to the working habits of professional photographers. In spare parts, the device is easily transportable.
D'autres configurations non représentées autorisent des déplacements de grande amplitude, au delà de 3 mètres et sans autre limitation que celles induites par la solidité du dispositif. Il est alors nécessaire d'utiliser des rails plus lourds, des entretoises renforcées, une articulation élaborée à la place du clamp (2), un mât renforcé mécanique ou hydraulique, ou bien toute combinaison de ces adaptations. Other configurations, not shown, allow displacements of great amplitude, beyond 3 meters and without other limitation than those induced by the solidity of the device. It is then necessary to use heavier rails, reinforced spacers, an articulation developed in place of the clamp (2), a reinforced mechanical or hydraulic mast, or any combination of these adaptations.
Le dispositif 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, plans, cartes ou décors), pour des prises de vues dans un laboratoire ou
bien à partir de maquettes. The device is particularly intended for photography, cinematography or video. The support then accommodates a lighting system, a device for taking
views, or both. This is the case, for example, for the reproduction of works of art
(tables, plans, maps or decorations), for taking pictures in a laboratory or
well from models.
