Abstract

Device for fixing a camera onto a motorised microlight, for taking vertical aerial shots. The invention relates to an underslung device making it possible to take unblurred aerial shots by damping the vibrations due to the engine of the airborne carrying vehicle, and by maintaining a perfect vertical whatever the position of the latter. The device consists of a pendulum 5 containing a roll shaft 7, fixed to a roll shaft support 4, and a pitch shaft 6, and linked, by means of an elastic coupling 3 and of a clamping nut 2, to a fixed shaft 1 on the one hand, and to the movable support 8 of the camera, on the other hand.

Description

DESCRIPTION
La presente invention concerne un dispositif de fixation d'un appareil de prise de vues sur un ultra-leger motorise (U.L.M.) pour prise de vue aérienne verticale.DESCRIPTION
The present invention relates to a device for fixing a camera on a motorized ultra-light (ULM) for vertical aerial photography.

La conception repose sur l'utilisation de la gravité par le biais d'un pendule qui vise diminuer l'influence du support.The design is based on the use of gravity through a pendulum which aims to reduce the influence of the support.

Les systèmes mécaniques traditionnellement utilises pour les prises de vues verticales (gyroscopes, centrale a inertie) nécessitent de grosses sources d'énergies et ne sont pas compatibles avec un support aerien léger.The mechanical systems traditionally used for vertical shots (gyroscopes, inertial unit) require large sources of energy and are not compatible with light aerial support.

Le dispositif selon l'invention permet de remedier à ces inconvenients.The device according to the invention makes it possible to remedy these drawbacks.

I1 ne nécessite en effet aucune source d'energie et son poids est de 20 kilogrammes. It does not require any source of energy and its weight is 20 kilograms.

I1 comporte un axe support fixe à chaque extremite sur 1'U.L.M. par silentblocs qui filtrent les vibrations dues au moteur du vecteur aerien. It has a fixed support axis at each end on the U.L.M. by silentblocs which filter the vibrations due to the engine of the air vector.

Sur cet axe est fixé une noix de serrage qui comporte deux demi-coquilles solidarisees par des boulons de serrage transversaux.On this axis is fixed a clamping nut which comprises two half-shells secured by transverse clamping bolts.

A la demi-coquille inférieure est fixé le support de l'axe de roulis. Ce support est maintenu à cette demi-coquille par un accouplement élastique.The support of the roll axis is fixed to the lower half-shell. This support is held at this half-shell by an elastic coupling.

L'axe de roulis porte un cardan comprenant le second axe (ou axe de tangage).The roll axis carries a universal joint comprising the second axis (or pitch axis).

Cet axe de tangage est solidaire du support de l'appareil de prises de vues.This pitch axis is integral with the support of the camera.

Ce support comporte une surface assurant la fixation par une vis transversale de l'appareil de prises de vues, une surface reliant la surface de fixation à l'axe de tangage, et une surface frontale de protection. Les dispositifs antivibratoires (silentblocs et accouplement élastique) sont réalises en mousse de caoutchouc dur. Les autres pièces du dispositif sont réalisées en acier.This support comprises a surface ensuring the fixing by a transverse screw of the camera, a surface connecting the fixing surface to the pitch axis, and a frontal protection surface. The anti-vibration devices (silentblocs and elastic coupling) are made of hard rubber foam. The other parts of the device are made of steel.

Le dispositif est d'une hauteur totale de 560 mm. La largeur est de 100 mm.The device has a total height of 560 mm. The width is 100 mm.

La profondeur est de 220 mm.The depth is 220 mm.

La figure 1/3 represente le plan d'ensemble du dispositif pendulaire de prises de vues sur 1'U.L.M. Figure 1/3 shows the overall plan of the pendulum camera on the U.L.M.

La figure 2/3 représente la vue de profil du dispositif selon l'invention.Figure 2/3 shows the side view of the device according to the invention.

La figure 3/3 représente la vue de face du dispositif selon l'invention.Figure 3/3 shows the front view of the device according to the invention.

Le dispositif représenté sur la figure 2/3 comporte un axe support (1) auquel est fixée une noix de serrage (2). Par l'intermédiaire d'un accouplement élastique (3), le support de l'axe de roulis (4) vient s'attacher à la noix de serrage (2). Un cardan (5) comprenant l'axe de tangage (6), est solidaire de l'axe de roulis (7). The device shown in Figure 2/3 has a support pin (1) to which is fixed a clamping nut (2). By means of an elastic coupling (3), the support of the roll axis (4) is attached to the clamping nut (2). A universal joint (5) comprising the pitch axis (6) is integral with the roll axis (7).

Le support de l'appareil de prise de vues (8),solidaire de l'axe de tangage (6), comporte une surface (9) de fixation de l'appareil de prise de vues, à laquelle est fixée une plaque de maintien (10) de l'appareil de prises de vues et une surface (11) reliant la surface de fixation (9) à l'axe de tangage (6), et portant la surface frontale de protection (12). The support for the camera (8), integral with the pitch axis (6), has a surface (9) for fixing the camera, to which is fixed a retaining plate (10) of the camera and a surface (11) connecting the fixing surface (9) to the pitch axis (6), and carrying the front protective surface (12).
