摘要
The invention relates to a device ensuring the even displacement of a support along a straight path of several metres and of any orientation. It is made up of an adjustable fixed leg (1) surmounted by a clamp (2), and of two orientable rails (3 and 4) held apart by spacer pieces (5 to 9). The clamp (2) clamps the spacer piece (7) at the centre of gravity of the orientable device (10). The orientable support (11) runs on one of the rails (4) and a counterweight (12) runs on the other rail (3). These two movements, which are symmetrical with respect to the centre (10), are provided for by a motor (13) mounted on the spacer piece (6) and two systems of pulleys (14 and 15) mounted on the end spacer pieces (5 and 9). A fixed counterweight (16) is mounted on the spacer piece (8). The movement of the support is adjustable in terms of amplitude and in terms of speed (17). The device is particularly intended for photography, cinematography, or video. The support therefore accommodates a lighting system, a camera, or both. IMAGE
