Abstract

The system has mobile pads (5, 5') displaced with respect to a body (1) and a fixation device (4) that fixes an equipment in an aircraft. The displacements of the mobile pads are operated by adjusting screws (2, 2'), respectively. The displacements of the mobile pads are controlled by pressure screws (6, 6') for changing distance between support planes according to need so as to optimize locking of the fixation device in walls of a rail (3) of the aircraft, respectively.

Description

La présente invention concerne un système d'ajustement pour dispositifs de fixation d' équipements embarqués à bord d'aéronefs devant s'adapter à divers types de rails avions. Les systèmes existants ne permettent pas l'ajustement des dispositifs de fixation dans les divers types de rails avions compte tenu du fait que les rails avions sont différents quant à l'épaisseur des parois et la profondeur de la gorge selon les aéronefs et les charges qu'ils doivent recevoir. La présente invention remédie à ce problème car elle permet aux dispositifs de fixation dont les systèmes de verrouillage sont adaptés à un seul type de rail, de s'adapter à des rails avions de toutes dimensions. En effet, l'invention a pour particularité de faire varier, selon besoin, la distance entre les plans A0 d'appui afin d'optimiser le verrouillage du dispositif de fixation dans les parois du rail avion. Ces variations rendent possible, au plus juste, les liaisons nécessaires entre les éléments d'arrimage du dispositif de fixation d'équipements et les parois du rail quelles que soient leurs dimensions. De plus, la présente invention peut s'adapter sur tous types de dispositif de fixation À 5 d'équipements dans les rails avion au moyen d'une interface. L'invention consiste en au moins un élément mobile se déplaçant par rapport à un ou plusieurs éléments du dispositif de fixation. Chacun des éléments ayant des appuis sur des plans différents du rail avion. Le fonctionnement du système d'ajustement s'opère par déplacement de deux éléments mobiles l'un par rapport à l'autre et pouvant être solidaires du dispositif de fixation. Le déplacement peut être bridé à tout moment selon besoin. ; le système peut être verrouillé à tout moment de sa course. Une commande de réglage permet de faire fonctionner le système. Ce système d'ajustement peut avantageusement équiper les dispositifs de fixation d'équipements aux rails avions couverts par les brevets N° 02 02964, N° 04 12036, N° 05 11980, N°07 01318 î 5 du même inventeur. Il peut être indifféremment couplé au dispositif de fixation d'équipement ou bien séparé à réglage indépendant. Dans une réalisation particulière de l'invention le système d'ajustement est constitué de deux patins d'appui qui coulissent dans un corps. Ce corps est taraudé pour recevoir deux vis de réglage qui en tournant permettent le déplacement entre les patins et le corps.The present invention relates to an adjustment system for equipment attachment devices on board aircraft to adapt to various types of aircraft rails. Existing systems do not allow adjustment of the fasteners in the various types of aircraft rails given that the aircraft rails are different in the thickness of the walls and throat depth depending on the aircraft and the loads they must receive. The present invention overcomes this problem because it allows fasteners whose locking systems are adapted to a single type of rail, to adapt to aircraft rails of all sizes. Indeed, the invention has the particularity to vary, as necessary, the distance between the support planes A0 to optimize the locking of the fastening device in the walls of the aircraft rail. These variations make it possible, as accurately as possible, the necessary connections between the securing elements of the device for fastening equipment and the walls of the rail whatever their dimensions. In addition, the present invention is adaptable to all types of equipment fasteners in aircraft rails by means of an interface. The invention consists of at least one movable element moving relative to one or more elements of the fixing device. Each of the elements having supports on different planes of the rail plane. The operation of the adjustment system is effected by moving two movable elements relative to each other and can be secured to the fastener. The displacement can be clamped at any time as needed. ; the system can be locked at any moment of its race. An adjustment command is used to operate the system. This adjustment system may advantageously equip equipment attachment devices to the rails of aircraft covered by patents No. 02 02964, No. 04 12036, No. 05 11980, No. 07 01318 of the same inventor. It can be indifferently coupled to the device fixing device or separated independently. In a particular embodiment of the invention the adjustment system consists of two support pads which slide in a body. This body is tapped to receive two adjusting screws which rotating allow movement between the pads and the body.

3 Deux vis de pression viennent en appui sur les patins et verrouillent dans le rail avion le dispositif de fixation d'équipements auquel l'invention est reliée. La Figure N° 1 présente une vue 3/4 du système d'ajustement dont le corps (1) est relié à un dispositif de fixation d'équipements (4) et dont les vis de réglage (2, 2') permettent le réglage en hauteur du système d'ajustement La Figure Na 2 est une vue latérale du système d'ajustement montrant les patins (5, 5') bloqués en hauteur par les vis de réglage (2, 2') et par les vis de pression (6, 6') permettant un ajustement afin que le système de fixation d'équipements (4) puisse s'adapter aux rails avion (3) de différents types. 3 two pressure screws rest on the pads and lock in the rail plane the device for attaching equipment to which the invention is connected. Figure N ° 1 shows a 3/4 view of the adjustment system whose body (1) is connected to an equipment fixing device (4) and whose adjustment screws (2, 2 ') allow the adjustment height of the adjustment system Figure Na 2 is a side view of the adjustment system showing the pads (5, 5 ') locked in height by the adjusting screws (2, 2') and the set screws ( 6, 6 ') allowing adjustment so that the equipment attachment system (4) can be adapted to the aircraft rails (3) of different types.
