Definitions

  • the present invention relates to the field of lighting and more precisely to a device for orienting a lighting apparatus such as, in particular but not exclusively, an encased lamp.
  • these comprise a spotlight fixed to the inside of a fixed support which normally is a ring shaped support suited to engage in a seat formed in a wall or ceiling of the space to be illuminated.
  • the latter is mounted in a mobile support of a tubular form, substantially in the shape of an elbow, which is able to slide in an arcuate guide connected to the fixed support.
  • the sliding point of connection between the guide and the mobile support moves integrally with the latter along a curvilinear trajectory defined by the arc shaped guide, thus allowing the entire mobile support to rotate around an ideal point in space, with the result of a extraction movement (and the inverse) of the mobile support relative to the fixed support.
  • the arc shaped guide can in turn rotate axially 360° with respect to the fixed support since it is integral with an annular element which engages circumferentially in a sliding manner in an annular seat formed in the fixed support itself.
  • the orientation consists, therefore, in an extraction movement (and the inverse) and a movement of axial rotation.
  • the type of lamp just described has, however, the inconvenience that, in order for the mobile support to be extracted (and the inverse), it is often necessary to intervene on a locking screw which, when the encased lamp is already mounted, is difficult to access and, in any case, cannot be reached without dismounting the entire lamp from its seat.
  • a locking screw which, when the encased lamp is already mounted, is difficult to access and, in any case, cannot be reached without dismounting the entire lamp from its seat.
  • two distinct inconveniences occur in any case.
  • the first is that the locking screw loosens easily, for example with the use or in the presence of vibrations, causing an undesired change of position of the spotlight.
  • the arcuate guide can become deformed and consequently abut against the mobile support itself.
  • the mobile support is in the shape of an elbow hinged to the fixed support, and locking it in a chosen position is carried out by means of a screw or clamp which causes the interference of an element frictioning against the external surface of the mobile support itself.
  • a screw or clamp which causes the interference of an element frictioning against the external surface of the mobile support itself.
  • the object of the present invention is to provide a device for orienting a lighting apparatus which allows both the person installing the lamp and the person using it to easily vary its position at any time without having to act on locking means or dismount the lamp in any way and which does not present the further inconveniences of the known devices described above.
  • the orientation device whose novel feature is that the mobile support is rotationally connected to the fixed support so that the former can be extracted from the latter, and that an arcuate rod is provided substantially concentric with the rotatable point of connection of the mobile support with respect to the fixed support with which it is integral, said rod engaging in a frictioned sliding manner in a vice integral with the mobile support.
  • the rod is an arcuate cylindrical element which engages in a rectilinear hole formed in the vice, so that a frictioned sliding is caused by the friction between the curved tract of the rod and the cylindrical walls of the hole.
  • the rod is simply an arcuate spring projecting from the fixed support.
  • the fixed support is preferably formed by an external ring, which can be encased in a wall or ceiling, and an internal ring which engages circumferentially in a sliding manner in the external ring.
  • an orientation device is applied to a lighting apparatus of the type to be encased in a wall or ceiling comprising a fixed support 1 to which is rotatably connected a mobile support 2 comprising a plate 3 and an ogive wall 4 to the internal part of which a spotlight 5 with its relative light socket 6 is fixed.
  • Fixed support 1 comprises an external ring 8 necessary for the encasement of the apparatus and an internal ring 9 which engages circumferentially in a sliding manner in external ring 8.
  • Rod 11 can be, for example, composed of a portion of steel thread and have, therefore, with respect to end 11a, a certain elasticity and flexibility equal to that of a spring.
  • a vice 13 having a ferrule 14 with a rectilinear axial hole 15 in which rod 11 slidingly engages.
  • end 3b of plate 3 abuts against a step 16 formed on the inside of internal ring 9 of fixed support 1.
  • the main advantage of the device according to the present invention is that, thanks to the frictioned coupling of the vice and the rod, the new position reached by the spotlight, after the extracting or inserting rotation carried out by the user, is absolutely stabile even in the presence of vibrations and at the same time is extremely simple to shift to a new position without having to dismount the lamp or intervene on the locking means.
  • Ferrule 14, furthermore, does not require any adjustment or maintenance since the resistance to sliding of rod 11 is provided essentially by a geometric interference with the rectilinear form of hole 15.
