Description
La présente invention est relative à un stabilisateur pour appareil de prise de vues. The present invention relates to a stabilizer for a camera.
Il est bien connu que la prise de vues en vidéo exige une grande stabilité de l'appareil de capture et, que l'appareil soit tenu à la main ou fixé 10 sur un support en mouvement, les mouvements brusques transmis audit appareil dégradent la qualité de l'image. It is well known that video shooting requires a great stability of the capture apparatus and, whether the apparatus is held in the hand or attached to a moving medium, the sudden movements transmitted to said apparatus degrade the quality of the image.
Pour remédier à ces inconvénients, il a été créé des stabilisateurs comportant une masse équilibrant celle de l'appareil de prise de vues. Ainsi on connaît un stabilisateur dont le montant reliant l'appareil à sa masse d'équilibrage est relié à un harnais porté par l'opérateur. Ce matériel est encombrant, onéreux et nécessite un long apprentissage. To overcome these drawbacks, stabilizers have been created with a mass balancing that of the camera. Thus we know a stabilizer whose amount connecting the device to its balance weight is connected to a harness worn by the operator. This material is bulky, expensive and requires a long learning.
20 II existe, aussi, des dispositifs sans harnais, mais il s'avère qu'avec ceux-ci l'orientation de l'appareil de prise de vues est difficile. There are also devices without harness, but it turns out that with them the orientation of the camera is difficult.
Le dispositif de l'invention, qui remédie à ces inconvénients, est constitué de deux parties à savoir un support tenu, manuellement, par 25 l'opérateur ou fixé sur un support en mouvement, et un équipage mobile, comportant l'appareil de prise de vues et sa masse d'équilibrage, ledit équipage reposant, en son centre de gravité, sur un pivot dudit support. The device of the invention, which overcomes these drawbacks, consists of two parts, namely a support held manually by the operator or fixed on a moving support, and a movable element comprising the gripping apparatus views and its balancing mass, said crew resting in its center of gravity on a pivot of said support.
De cette façon, en raison de l'inertie de l'équipage mobile, un 3o tressaillement du support n'est pas transmis à l'équipage mobile. 15 Des moyens sont prévus pour transmettre un déplacement volontaire du support, dans l'une ou plusieurs des trois directions de l'espace, à l'équipage mobile. In this way, due to the inertia of the moving equipment, a thrill of the support is not transmitted to the moving equipment. Means are provided for transmitting a voluntary movement of the support, in one or more of the three directions of space, to the moving equipment.
Les moyens précités ont pour effet de permettre le déplacement de l'équipage mobile à une vitesse qui ne dépende pas de celle de déplacement du support mobile mais qui soit plus faible et adaptée à l'obtention d'images correctes : le déplacement est amorti. The aforementioned means have the effect of allowing the movement of the moving equipment at a speed which does not depend on that of displacement of the mobile support but which is lower and adapted to obtain correct images: the displacement is damped.
La présente invention sera mieux comprise par la description qui va 15 suivre faite en se référant aux dessins annexés à titre d'exemple indicatif seulement sur lesquels : - la figure 1 est une vue en perspective montrant les deux parties du dispositif de l'invention ; - la figure 2 est une vue en perspective montrant le dispositif en position 20 d'utilisation ,- -la figure 3 est une vue partielle, en coupe verticale et à plus grande échelle de la figure 2 ; - la figure 4 est une vue en perspective du dispositif complétée par des moyens permettant d'entraîner l'équipage mobile ; 25 -la figure 5 est une vue, analogue à celle 4, montrant une autre forme de réalisation ; - la figure 6 est une vue schématique montrant le principe de fonctionnement du dispositif d'entraînement du mode de réalisation de la figure 5. The present invention will be better understood from the following description with reference to the accompanying drawings by way of example only, in which: FIG. 1 is a perspective view showing the two parts of the device of the invention; FIG. 2 is a perspective view showing the device in the position of use, FIG. 3 is a partial view, in vertical section and on a larger scale of FIG. 2; FIG. 4 is a perspective view of the device completed by means making it possible to drive the mobile equipment; FIG. 5 is a view, similar to that 4, showing another embodiment; FIG. 6 is a schematic view showing the operating principle of the drive device of the embodiment of FIG. 5.
30 En se reportant, notamment, à la figure 1, on voit que le dispositif comporte, principalement, deux parties 1 et 2. Referring, in particular, to FIG. 1, it can be seen that the device comprises, mainly, two parts 1 and 2.
La partie 1 est constituée par un support affectant, sensiblement, la forme d'une équerre dont l'aile verticale 1 a supporte une poignée 1 b, constituée par exemple par une barre transversale, tandis que l'aile horizontale 1c comporte un pivot 3, constitué par exemple par un corps sphérique. Part 1 is constituted by a support substantially affecting the shape of a bracket whose vertical flange 1 has a handle 1b, constituted for example by a transverse bar, while the horizontal flange 1c comprises a pivot 3 , constituted for example by a spherical body.
La partie 2 est constituée par l'appareil de prise de vues et par sa masse d'équilibrage, ces deux organes étant représentés schématiquement et désignés par les références 4 et 4a, lesdits organes étant réunis par un montant 5 comportant un décrochement 6. Le montant 5 comporte un organe 7 présentant une cavité 7a, débouchant vers le bas dont le fond semi sphérique peut venir coiffer le pivot 3. L'organe 7 est disposé de façon à ce que, lorsque la partie 2 est 20 montée sur celle 1, le centre de gravité de ladite partie 2 soit sensiblement confondu avec celui de la partie sphérique constituant le pivot. Part 2 is constituted by the camera and its balancing mass, these two members being shown schematically and designated by references 4 and 4a, said members being joined by an amount 5 comprising a recess 6. The amount 5 comprises a member 7 having a cavity 7a, opening downwards whose semi-spherical bottom can cap the pivot 3. The member 7 is arranged so that, when the portion 2 is mounted on the 1, the center of gravity of said portion 2 is substantially coincident with that of the spherical portion constituting the pivot.
Les frottements entre les organes en contact des parties 1 et 2 étant pratiquement nuls, un mouvement intempestif transmis à la partie 1 par 25 l'opérateur sera sans effet sur celle 2. As the friction between the members in contact of the parts 1 and 2 is practically nil, an inadvertent movement transmitted to the part 1 by the operator will have no effect on that 2.
Dans ce qui va suivre, on va décrire des moyens permettant d'entraîner la partie 2, le but des moyens mis en oeuvre étant de transmettre le déplacement sans risquer d'altérer la qualité des images prises. Une première solution consiste à fixer sur le support 1 des aimants produisant des champs dans les trois dimensions de l'espace et à placer dans ces champs des aimants portés par la partie 2, les aimants étant disposés de 30 façon à ce que ceux de la partie 1 tendent à repousser ceux en vis-à-vis de la partie 2. In what follows, we will describe means for driving the part 2, the purpose of the means used is to transmit the movement without risking to alter the quality of the images taken. A first solution is to fix on the support 1 magnets producing fields in the three dimensions of the space and to place in these fields magnets carried by the part 2, the magnets being arranged in such a way that those of the part 1 tend to push those opposite part 2.
Pratiquement, les aimants de la partie 1 sont disposés sur les champs internes d'une cage constituée par l'association de deux armatures 8 et 9, en 10 forme d'U, rendues chacune solidaire par leur partie médiane de ladite partie Practically, the magnets of part 1 are arranged on the internal fields of a cage formed by the combination of two U-shaped frames 8 and 9, each secured by their middle portion of said portion.
A chacune de ces armatures aimantées est associée une galette aimantée, respectivement 10 et 11, portée par le montant 5, chaque galette 15 est sensiblement disposée dans le plan de l'armature correspondante, mais cette disposition n'est pas impérative. To each of these magnetized armatures is associated a magnetized wafer, respectively 10 and 11, carried by the amount 5, each wafer 15 is substantially disposed in the plane of the corresponding armature, but this provision is not imperative.
Si l'armature est brusquement déplacée, de façon par exemple, à pivoter selon un axe vertical, la partie 2, par inertie, reste sur place, l'appareil 20 de prise de vues ne bouge pas. If the armature is suddenly moved, for example, to pivot vertically, the part 2, inertia, remains in place, the camera 20 does not move.
Toutefois lors de ce pivotement, l'une des branches de l'armature 8 s'est rapprochée de la galette 10, l'équilibre est rompu et l'aimant de ladite branche va repousser la galette et forcer la partie 2 à pivoter sans 25 mouvement brusque nuisible à la qualité de l'image. However, during this pivoting, one of the branches of the armature 8 has approached the slab 10, the balance is broken and the magnet of said arm will push the slab and force the part 2 to rotate without sudden movement harmful to the quality of the image.
II ressort des explications ci-dessus que la rapidité de déplacement de la partie 2 est pratiquement indépendante de celle de déplacement de la partie 1 portée par l'opérateur, les mouvements brusques de cette dernière se 30 trouvant amortis. From the above explanations it follows that the speed of movement of the part 2 is practically independent of that of the movement of the part 1 carried by the operator, the abrupt movements of the latter being damped.
Comme cela ressort de la figure 5, un résultat analogue peut être obtenu par des moyens mécaniques. As can be seen in FIG. 5, a similar result can be obtained by mechanical means.
Selon un mode de réalisation, la partie 1 supporte trois paires de poulies 12, les poulies de chaque paire étant réunies par une courroie 13 élastiquement déformable. Les poulies peuvent être remplacées par des doigts fixes. 10 Ces trois ensembles 12-13 sont disposés de façon à ce que les brins des courroies de chaque ensemble s'étendent, respectivement, parallèlement aux trois directions de l'espace définies par les axes X, Y et Z de la figure 5. According to one embodiment, the part 1 supports three pairs of pulleys 12, the pulleys of each pair being joined by an elastically deformable belt 13. The pulleys can be replaced by fixed fingers. These three sets 12-13 are arranged in such a way that the strands of the belts of each set extend, respectively, parallel to the three directions of space defined by the X, Y and Z axes of FIG. 5.
15 Entre les brins de chaque paire s'étend un doigt de la partie 2. Ce doigt peut être fixe ou pivoter librement selon axe. Between the strands of each pair extends a finger of part 2. This finger can be fixed or pivot freely along the axis.
Pour l'axe X, il s'agit d'un doigt 6b formant le prolongement de la partie supérieure 6a du décrochement 6, pour l'axe Y, il s'agit de ladite partie 6a et 20 pour l'axe Z, il s'agit de la partie inférieure 5a du montant 5. For the X axis, it is a finger 6b forming the extension of the upper part 6a of the recess 6, for the Y axis, it is said part 6a and 20 for the Z axis, it this is the lower part 5a of the amount 5.
La figure 6 est une vue schématique montrant la paire dont les brins de la courroie s'étendent parallèlement à l'axe Y. Figure 6 is a schematic view showing the pair whose strands of the belt extend parallel to the Y axis.
25 Si le support 1, entraîné par l'opérateur, pivote selon un axe vertical, le « doigt » 5a va déformer élastiquement le brin 13a qui, ensuite, va se détendre et, en repoussant ledit doigt, va faire pivoter la partie 2 à une vitesse qui n'est pas directement liée à celle de rotation de ladite partie 1, les mouvements brusques se trouvant amortis. 30 II ressort de l'ensemble des explications ci-dessus qu'il est possible, par un choix judicieux des aimants, de leur force et de leur positonnement, de même que par un choix judicieux des courroies, d'obtenir une vitesse de5 déplacement de la partie 2 qui, tout en étant dépendant de celle de la partie 1, ne soit pas proportionnelle à celle-ci mais, soit compatible avec l'obtention d'images de bonne qualité. If the support 1, driven by the operator, pivots about a vertical axis, the "finger" 5a will elastically deform the strand 13a which will then relax and, by pushing said finger, will rotate the part 2 to a speed which is not directly related to that of rotation of said part 1, the sudden movements being damped. From all of the above explanations, it is possible, by a judicious choice of the magnets, their strength and their positron, as well as by a judicious choice of the belts, to obtain a speed of displacement. part 2 which, while being dependent on that of part 1, is not proportional to it but is compatible with obtaining good quality images.
La liaison entre la partie 1 et celle 2 peut être réalisée par un dispositif 10 de suspension à la Cardan. - The connection between the part 1 and the 2 can be achieved by a device 10 suspension cardan. -
