Definitions

  • ABSTRACT A light column is made up of signalling units arranged, one on top of the other, each of the units comprising inside a transparent glass casing of cylindrical shape, fixed conductors which pass through it.
  • the number of said conductors corresponds to the maximum number of signalling units that can be accomodated plus one return conductor common for all signalling units, each 'of these units being closed at one end by an opaque solid partition comprising support means for the said'electric bulb and fastening means of a first type, while the other end comprises an annular partitioning portion which gives access to the electric bulb and includes fastening means of a second type whose shape enables them to engage with said fastening means of the first type, when the two adjoining signalling units are in one particular relative position, obtained by partial relative rotation of the said two .adjoining units.
  • the invention relates to light columns designed to indicate to staff supervising automatic machines installed in large areas the occurrence of incidents such as fa-ult conditions.
  • a light column which is made up of annular-shaped signalling units, at least partly transparent, positioned coaxially one above the other, wherein an electric bulb is fitted in each of the units so that the latter is only lit up when the line which feeds it becomes energized, the various feed lines coming from a base which supports the device.
  • This known'device comprises many faults.
  • a single device for holding the units is provided, which makes dismantling-tedious when only one bulb has to be replaced, especially if it is the bulb at the bottom; then the column is usually overheated at the top due to the internal shape ,of the units, which allows hot air to rise', finally, the network of conductors making up the feed lines, together with the fixing system, form an opaque screen, so that there are large shaded areas in certain zones.v It may also be mentioned that it is not possible, to combine these units, all of the same color or any combination whatever of colors, without making mechanical adjustments.
  • this column constitutes a device comprising removable light units which can be assembled and dismantled quickly and in any order without special tools.
  • each signalling unit in the Vcolumn comprises fixed conductors inside a transparent glass casing of cylindrical shape, the number of these conductors corresponding to the maximum number of signalling units that can be accomodated in one column plus one return conductor common for all units, the casing being closed at one end by a solid opaque partition comprising support means for an electric bulb and a first type of fastening means, while the other end of the casing comprises an annular partitioning portionwhich givesY access to the electric bulb and includes a second type of fastening means whose shape enables it to be engaged with the first type of fastening means when the two adjoining signalling units are in one particular relative position.
  • the fixed conductor units consist of metal blades parallel to the axis of the column, said blades being anchored in the said solid opaque partitions and said annular partitioning portions and having at their ends complementarily shaped means of electrical connection which become operative when two adjoining signalling units are fastened together.
  • FIG. l shows an elevational view of a light column in accordance with a preferred form of embodiment of the invention
  • FIG. 2 is a partial sectional view of this column in an axial plane
  • FIG. 3 is a view from above of one of the fixed conductors comprised therein.
  • FIG. l shows a complete light column mounted on a machine frame 6.
  • the device consists of a base l, on which is fixed a leg 2, generally cylindrical, which in turn supports a collar 3 on which the first of a set of super-imposed signalling units 9 is fitted. The last unit is closed with a cover 5.
  • the column shown comprises five units, but this is by no means the maximum number.
  • a certain number of electric leads 7 terminate at the device and feed the bulbs (described below) when two or more of these leads are energized due to the occurence of the phenomenon or fault to be indicated.
  • the units in the column are identical, except that the colours of the transparent glass casings (4, FIG. 2) can be different.
  • a solid, nonnon-transparent partition 8 is fixed (FIG. 2).
  • Electric conductors I7 and 19 are fixed on this partition, these conductors 17 are equal in number to the leads 7, their number corresponding to the maximum nurnber of signalling units that can be accomodated, plus one return conductor common for all units, the said common conductor and a specific conductor permit ting current to flow through a specific removable bulb 15 to illuminate the associated glass casing.
  • the glass casing is, moreover, designed to provide two different illuminated' areas: on the one hand, a central translucent annular focalizing ⁇ area for the light from the electric bulb, this area being obtained by means of an annular spherical inner surface 20 placed in the central area and acting as a lens; on the other hand, two diffusing translucent annular areas for the light from said bulb, consisting of two annular portions 21 and 22 positioned on either side of the spherical surface 20 and with pyramid-shaped points placed on their inside surface.
  • each electric bulb 15 is connected, in a way not shown, to two of the conductors in a set of fixed conductors ll.
  • the latter are housed inside the glass casing and anchored at their respective ends in the solid bottom partition 8 and in an annular partitioning portion l0 at the top of the unit.
  • Each conductor 1l is made up of a blade the plane of which passes through the axis of the column; at the bottom, it has a male portion 13 and at the top, a flexible female portion 14, and the portions 13 and 14 constitute the aforementioned means of electrical connection.
  • the shapes of these two portions are complementary, so that superimposing two signalling units (as shown in FIG. 2) unfailingly causes two conductor ends belonging to these two units to make contact.
  • the male portion 13 is obtained by making a 90 twist at the bottom end of the blade 1l.
  • the flexible female portion 14 is shown more clearly in FIG. 3.
  • the shape ofthe electrical connection means is designed so that their connection is achieved by way of a limited relative rotation of two adjoining signalling units.
  • the mechanical fastening of the two units is, moreover, carried out during this rotation, by collaboration between fastening means of a first type 16 and fastening components of a second type l2.
  • the means 16 are portions of helicoidal ramps connected to a crown 18 fixed to the partition 8 so as to give a certain amount of axial flexibility.
  • FIG. 2 shows that onev of these ramps 16 is simply applied against a helicoidal projection l2 being part of the partition portion 10.
  • the top partition of the unit should not be completely closed, so that the bulb can be changed.
  • a solid partition at this level would serve no purpose, in view ofthe immediate proximity of the solid partition 8 of the superimposed unit, which partition 8 prevents a glass casing from being lit up by the bulb in the adjoining glass casing. It also prevents hot air from rising which would shorten the life of the bulbs.
  • the fastening components can be spaced irregularly around the axis of the column; one of the ramps 16 can also be externally shaped so that its profile corresponds with a single notch in the complementary fastening component, throughv which it will have to penetrate.
  • the signalling units may not be annular.
  • the first and second type fastening components can consist of various devices known in themselves, such as: fixing by means of a catch, by passing a dead point, by screwing, by radial movement, or even by means of suction discs or magnetic components.
  • the means of electrical connection can consist of contact devices with axial flexibility, while the fixed conductors can be cylindrical and, possibly, by embedded inthe material of the glass casing.
  • a unit can also be made entirely of the transparent material of the glass casing, providing it is equippedwith a nontransparent solid partition, e.g. by metal plating, painting or any chemical treatment.
  • each signalling unit comprises, inside a transparent glass casing of cylindrical shape, fixed conductors which pass through it, the numberof said conductors corresponding to the maximum number of signalling units that can be accomodated plus one return conductor common for all signalling units, each of these units being closed at one end by an opaque solid partition comprising support means for the said electric bulb and fastening means of a first type, while the other end comprises an annular partitioning portion which gives access to the electric bulb and includes fastening means of a second type whose shape enables them to engage with said fastening means of the first type, when the two adjoining signalling units are in one particular relative position, obtained by partial relative rotation of the said two adjoining units.
  • a light column in accordance with claim l characterized in that the said fixed conductors consist of metal blades parallel to 'the axis of the column and anchored in said opaque solid partition and in said annular partitioning portion, and have at their ends electrical contact means of complementary shape and engaging in one another when two adjoining signalling units are fastened together.
  • a light column according toclaim l in which the conductor blades are arranged inv axial planes in a way to cause minimum obstruction to the light radiated from the electric bulb, and the said common conductor and one specific conductor for each unit are connected to the electricbulb fitted in the said signalling unit.
  • a light column in accordance with claim l characterized in that the glass casing of cylindrical shape comprises a central translucent annular focalizing area for,
  • the light from the said electric bulb and on either side of the said focalizing area, two diffusing translucent annular areas for the light from the said electricfbulb, the first area consisting of an inner annular spherical surface of the glass casing forming a lens and the two other areas consisting of portions of the inside surface of the glass casing having pyramid-shaped points.
