Description

-1,- La présente invention concerne un dispositif permettant de supporter-1, - The present invention relates to a device for supporting

une caméra et de laa camera and

déplacer afin d'obtenir des prises de vues zénithales sous des angles variés.  move to get overhead shots from various angles.

L'intérêt croissant pour la couverture médiatique des événements sportifs donne lieu aujourd'hui à un climat de concurrence exacerbée entre les chaînes de télévision désirant en acquérir les droits exclusifs de retransmission. Le profit commercial qu'elles en retirent est indéniable, il explique les situations de surenchère. Dans le même temps, le téléspectateur devient plus exigeant sur la qualité et la variété des images qui lui sont proposées, d'o l'obligation faite aux chaînes, d'améliorer constamment leurs diffusions. Pour s'en convaincre il suffit de considérer l'augmentation sensible du nombre de caméras autour des rencontres sportives, notamment les matchs de football. Quel est le but recherché, sinon la multiplication des angles de prises de vues? Si les changements d'angles de prises de vues sont facilement envisageables pour des caméras placées sur le sol ou en hauteur, les vues zénithales sont elles beaucoup plus délicates à obtenir. Bien qu'elles présentent un fort intérêt pour l'analyse tactique, mais aussi pour leur côté spectaculaire, elles restent rares sur les ecrans. En effet, la majorité des stades n'étant pas  The growing interest in the media coverage of sporting events gives rise today to a climate of exacerbated competition between the television channels wishing to acquire the exclusive rights of retransmission. The commercial profit which they derive from it is undeniable, it explains the situations of overbidding. At the same time, the viewer becomes more demanding on the quality and variety of the images which are proposed to him, from the obligation made to the channels, to constantly improve their broadcasts. To be convinced of this, it suffices to consider the appreciable increase in the number of cameras around sporting events, in particular football matches. What is the goal, if not the multiplication of angles of shots? If the changes of angles of shots are easily possible for cameras placed on the ground or in height, the overhead views are much more difficult to obtain. Although they are of great interest for tactical analysis, but also for their spectacular side, they remain rare on the screens. In fact, the majority of stadiums not being

totalement couverts, l'installation de caméras placées à la verticale de la zone de jeu est impossible.  fully covered, the installation of cameras placed vertically above the playing area is impossible.

Dans le cas de stades couverts, dépourvus d'installations résidentes, l'utilisation de nacelles -  In the case of covered stadiums, devoid of resident facilities, the use of nacelles -

quand elles peuvent pénétrer dans les bâtiments - ou le montage d'échafaudages, sont des solutions coûteuses et très 'lourdes' techniquement. Par ailleurs, elles présentent toutes deux l'inconvénient majeur d'occuper une grande surface au sol, parfois même à l'intérieur de la zone de prises de vues. Autre inconvénient, elles peuvent gêner la vue des spectateurs. Les dispositifs appelés loumas' ont quant à eux des performances limitées en hauteur, si bien qu'une caméra fixée sur ce  when they can enter buildings - or erect scaffolding, are expensive and technically very heavy solutions. Furthermore, they both have the major drawback of occupying a large area on the ground, sometimes even inside the shooting area. Another drawback is that they can hinder the view of spectators. Devices called loumas' have limited performance in height, so that a camera fixed on it

type de matériel ne peut cadrer sur un plan fixe que l'espace déterminé par la focale de l'objectif.  type of material can only fit on a fixed plane the space determined by the focal length of the lens.

Le dispositif selon l'invention propose une solution simple et économique aux problèmes décrits précédemment. Il comporte en effet selon une première caractéristique, un treuil sur lequel s'enroule un câble pourvu d'un mousqueton en son extrémité. Sur le câble, tendu en fonction, roule un wagonnet motorisé dont le rôle est de déplacer le long du câble une tourelle d'orientation à deux axes motorisés. Cette tourelle est conçue pour supporter une caméra et son objectif au-dessus de la zone dans laquelle doivent s'effectuer les prises de vues. L'orientation de la visée est assurée par la tourelle deux axes motorisés. Le premier axe dit de 'Pan' autorise la rotation autour d'un axe vertical, pour une couverture panoramique de 360 . Le deuxième axe dit de 'Tilt' autorise une  The device according to the invention offers a simple and economical solution to the problems described above. According to a first characteristic, it comprises a winch on which is wound a cable provided with a carabiner at its end. On the cable, stretched in function, rolls a motorized wagon whose role is to move along the cable an orientation turret with two motorized axes. This turret is designed to support a camera and its lens above the area in which the shots are to be taken. The orientation of the sighting is ensured by the turret two motorized axes. The first axis called 'Pan' allows rotation around a vertical axis, for panoramic coverage of 360. The second axis called 'Tilt' allows

rotation autour d'un axe horizontal, orthogonal au premier, et entramîné par la rotation du premier.  rotation around a horizontal axis, orthogonal to the first, and entramîne by the rotation of the first.

Ainsi, tout le demi-espace situé sous le dispositif est accessible à la visée. Pour assurer la translation de la tourelle deux axes motorisés et de la caméra, le wagonnet comprend une ou plusieurs roues motorisées roulant sans glissement le long du câble. Le poids de l'ensemble roulant, constitué du wagonnet, de la tourelle et de la caméra qu'elle embarque, doit suffire à maintenir un -2- effort normal assez grand entre le câble et la ou les roues motrices, de telle sorte qu'il n'y ait pas de risque de patinage. Dans l'hypothèse ou la flèche du câble est grande, provoquant une inclinaison sensible de sa ligne moyenne par rapport à l'horizontale, le wagonnet peut être conçu pour augmenter l'effort normal nécessaire au maintien de la motricité. Un système de galets exerçant une force réglable sur le câble, et montés en opposition avec la ou les roues motrices, permet de résoudre ce problème, il permet même d'envisager une utilisation dans des cas o les points  Thus, the entire half-space located under the device is accessible to aiming. To ensure the translation of the two-axis motorized turret and the camera, the wagon includes one or more motorized wheels rolling without sliding along the cable. The weight of the rolling assembly, consisting of the wagon, the turret and the camera it takes on, must be sufficient to maintain a fairly large normal effort between the cable and the driving wheel or wheels, so that 'there is no risk of skating. In the event that the cable deflection is large, causing a significant inclination of its mean line relative to the horizontal, the wagon can be designed to increase the normal effort required to maintain motor skills. A system of rollers exerting an adjustable force on the cable, and mounted in opposition with the driving wheel or wheels, makes it possible to solve this problem, it even makes it possible to envisage use in cases where the points

d'ancrages de l'extrémité du câble et du treuil sont situés à des hauteurs différentes.  cable end and winch anchors are located at different heights.

Selon des modes particuliers de réalisation: - le treuil pourra être manuel ou électrique et sera impérativement équipé d'un système mécanique de sécurité interdisant tout dévidage accidentel, qui mettrait en danger les personnes situées sous le dispositif. En outre, le wagonnet motorisé sera équipé d'un anneau au travers duquel passera le câble, ceci pour prévenir la chute du wagonnet en cas de déraillement; - le wagonnet motorisé pourra recevoir un carénage de protection contre la pluie; - le wagonnet motorisé pourra être équipé d'un mécanisme d'absorption des vibrations produites lors de son roulement sur le câble; - un enrouleur de câble électrique pourra compléter le dispositif En maintenant une tension constante des câbles d'alimentation et de commande de la caméra, entre le wagonnet et un point situé à proximité du treuil, cet enrouleur évitera que ces câbles ne pendent sous le câble supportant le wagonnet. La tension exercée par l'enrouleur devra être la plus faible possible pour ne pas freiner ou accélérer trop sensiblement les déplacements du wagonnet motorisé; - le wagonnet pourra être équipé d'un mécanisme d'amortissement des effets mécaniques dus à des accélérations ou décélérations trop brusques, ces effets pouvant nuire à la qualité des images obtenues; - le moteur du wagonnet pourra être commandé à distance par l'intermédiaire d'un boîtier électrique et/ou électronique de gestion de sa vitesse de déplacement sur le câble; - les moteurs des deux axes motorisés de la tourelle d'oriention pourront être commandés à distance par l'intermédiaire d'un boîtier électrique et/ou électronique; - pour une réduction de l'effet de 'roulis' du wagonnet, et une meilleure stabilité d'image en cas de fort vent en utilisation extérieure, au treuil, son câble et son mousqueton, peuvent être adjoints un second câble, un second treuil et un second mousqueton, le wagonnet motorisé étant alors conçu comme un petit véhicule à essieux avec une largeur de voie adaptée, roulant sur les deux câbles tendus parallèlement, en fonction; - les câbles pourront être métalliques, en matière plastique ou synthétiques, être gainés ou enrobés, afin d'offrir une surface de roulement la plus régulière possible; - des butés de forme cylindrique en mousse synthétique pourront être placées autour du câble -3- tendu, aux deux extrémités dudit câble. En cas d'erreur humaine de commande, elles pourront protéger la caméra contre des chocs qui l'endommageraient; - le châssis du wagonnet motorisé pourra être articulé afin de pouvoir tolérer un déplacement sur un ou des câbles tendus en lignes brisées, en ovales, ou en ronds, ayant des rayons de courbure dans un plan horizontal suffisamment grands pour que les virages soient pris sans déraillement;  According to particular embodiments: - the winch can be manual or electric and must be fitted with a mechanical safety system preventing any accidental unwinding, which would endanger the people located under the device. In addition, the motorized wagon will be equipped with a ring through which the cable will pass, this to prevent the fall of the wagon in the event of derailment; - the motorized wagon may receive a rain protection fairing; - the motorized wagon may be equipped with a mechanism for absorbing the vibrations produced during its rolling on the cable; - an electric cable reel can complete the device By maintaining a constant tension of the power and camera control cables, between the wagon and a point located near the winch, this reel will prevent these cables from hanging under the cable supporting the wagon. The tension exerted by the retractor must be as low as possible so as not to brake or accelerate the movements of the motorized wagon too much; - the wagon may be equipped with a mechanism for damping mechanical effects due to too sudden accelerations or decelerations, these effects being able to affect the quality of the images obtained; - the wagon motor can be controlled remotely by means of an electrical and / or electronic box for managing its speed of movement on the cable; - the motors of the two motorized axes of the orientation turret can be controlled remotely via an electrical and / or electronic box; - for a reduction of the 'roll' effect of the wagon, and a better image stability in case of strong wind in outdoor use, to the winch, its cable and its carabiner, can be added a second cable, a second winch and a second carabiner, the motorized wagon then being designed as a small axle vehicle with a suitable track width, rolling on the two cables stretched in parallel, in operation; - the cables can be metallic, plastic or synthetic, sheathed or coated, in order to provide the most regular running surface possible; - cylindrical stops of synthetic foam can be placed around the tensioned cable -3- at both ends of said cable. In the event of a human control error, they will be able to protect the camera against shocks which would damage it; - the chassis of the motorized wagon may be articulated in order to be able to tolerate displacement on one or more cables stretched in broken lines, in ovals, or in circles, having radii of curvature in a horizontal plane large enough for the turns to be taken without derailment;

- le wagonnet motorisé pourra être équipé d'un système de frein mécanique à commande électrique.  - the motorized wagon may be fitted with a mechanical brake system with electrical control.

I faut noter que la réduction continuelle du poids des caméras, aujourd'hui numériques, et la technique dite de 'caméra déportée', doivent autoriser de très bonnes performances, tant pour la distance couverte par les déplacements de la caméra que pour la vitesse à laquelle ils pourront s'effectuer. La recherche d'une inertie la plus faible possible doit permettre des mouvements  It should be noted that the continuous reduction in the weight of today's digital cameras and the so-called 'remote camera' technique must allow very good performance, both for the distance covered by the movement of the camera and for the speed at which they can perform. The search for the lowest possible inertia must allow movements

dynamiques et des images à l'avenant.  dynamics and images to match.

La figure 3 représente une vue d'une conception possible pour la tourelle d'orientation à deux axes motorisés. En référence à la figure 1, le dispositif comporte un treuil (1), pourvu d'un dispositif de sécurité à cames centrifugées, sur lequel s'enroule un câble (2) pourvu d'un mousqueton (3) en son extrémité. Sur le câble (2), tendu en fonction, roule un wagonnet motorisé (4) dont le rôle est de déplacer le long du câble (2) une tourelle d'orientation (5) à deux axes motorisés. Sur la tourelle d'orientation (5) sera fixée la caméra et son objectif Au-dessus du treuil (1) se trouve un enrouleur de câble électrique (6) duquel sortent les câbles nécessaires à la commande du moteur du wagonnet  FIG. 3 represents a view of a possible design for the orientation turret with two motorized axes. Referring to Figure 1, the device comprises a winch (1), provided with a centrifugal cam safety device, on which is wound a cable (2) provided with a carabiner (3) at its end. On the cable (2), tensioned in function, rolls a motorized wagon (4) whose role is to move along the cable (2) an orientation turret (5) with two motorized axes. On the orientation turret (5) will be fixed the camera and its objective Above the winch (1) is an electric cable reel (6) from which the cables necessary to control the motor of the wagon come out

motorisé (4), des moteurs de la tourelle d'orienrtation (5) et des fonctions de la caméra embarquée.  motorized (4), orientation turret motors (5) and on-board camera functions.

Depuis cet enrouleur de câble électrique (6), tous les câbles descendent vers leurs boîtiers de commande respectifs, parmi lesquels, le boîtier de commande à distance (7) du moteur du wagonnet motorisé (4) ainsi que le boîtier de commande des deux axes motorisés (8) de la tourelle d'orientation. En référence aux figures 1 et 2, le wagonnet motorisé (4) est composé d'un châssis (10) en aluminium sur lequel s'articule, par liaison pivot, un bras suspendu (11) en aluminium. Sur le châssis (10) sont montées une roue motrice (12), une roue libre (13) ainsi qu'un galet (14). Ce galet (14) est maintenu en pression contre le câble (2) par un système de glissière et ressort à contrainte réglable. Depuis le châssis (10) sur lequel il est en liaison pivot, un amortisseur double effet (15) relie le châssis au bras suspendu (11) avec lequel il est également en liaison pivot. Sur le bras suspendu (1 1), un moteur électrique à courant continu (16) est fixé. Un dispositif -4- démultiplicateur de vitesse par courroie (17) relie la poulie primaire (18) du moteur à courant continu (16) à la poulie secondaire (19) entraînant en rotation la roue motrice (12). Sur le châssis (10) est fixé un anneau de sécurité (20) au travers duquel passe le câble. A l'extrémité libre du bras suspendu (11) une platine (21) perforée d'un trou assure la liaison pivot entre elle et l'axe vertical de la fourche (22) de la tourelle d'orientation (5) à deux axes motorisés. La platmine (21) supporte également le moteur électrique de l'axe vertical (23) chargé de produire le mouvement panoramique de la camera par l'intermédiaire d'un système d'engrenage et vis sans fin (24) entrainant la fourche (22). En référence aux figures 1 et 3, la tourelle d'orientation (5) à deux axes motorisés comporte une fourche (22) en liaison pivot avec la platine (21) du wagonnet motorisé (4). Entre les deux bras de la fourche (22) se trouve l'axe horizontal (25) lui- même animé par un moteur électrique (26) en prise avec un second système d'engrenage et vis sans fin (27). La caméra sera fixée sur le méplat de l'axe horizontal (25) ou sur une pièce intermediaire dessinée en fonction de  From this electric cable reel (6), all cables descend to their respective control boxes, among which, the remote control box (7) of the motorized wagon motor (4) as well as the control box for the two axes motorized (8) of the orientation turret. Referring to Figures 1 and 2, the motorized wagon (4) is composed of an aluminum frame (10) on which is articulated, by pivot connection, a suspended arm (11) made of aluminum. On the chassis (10) are mounted a drive wheel (12), a free wheel (13) and a roller (14). This roller (14) is kept in pressure against the cable (2) by a slide and spring system with adjustable stress. From the chassis (10) on which it is pivotally connected, a double-acting damper (15) connects the chassis to the suspended arm (11) with which it is also pivotally connected. On the hanging arm (1 1), a direct current electric motor (16) is fixed.
