  • Device for angularly positioning a mass relative to a horizontal support axis and a lighting apparatus provided with such a device
    Patent number: 5971572
    Abstract: A device for the angular positioning of a mass with respect to a horizontal support axis includes a support arm intended to carry the mass and the mounted angularly displaceable about the support axis and the balancing device for balancing the arm connected thereto and cooperating with an elastic return member adapted to apply to a point of the support arm a mass balancing moment opposed to the moment generated by the weight of the mass. The assembly of the balancing member and the elastic return device is mounted oscillating on an oscillation axis parallel to the support axis and situated at a fixed distance therefrom so as to be orientated permanently towards the point during angular displacements of the support arm.
