Definitions
- the present invention which remedies these drawbacks, is remarkable in that this mast can pivot around a horizontal axis, from the vertical position of use to a substantially horizontal, idle position, with said mast extending beyond its axis of articulation in order to be provided with a balancing counterweight.
- the set of said projectors as a whole constitutes a substantial mass which require the use of latticework beams for the embodiment of such masts.
- the projector support assembly can slide along the mast and be lowered prior to the pivoting thereof.
- FIG. 1 is an elevation of a mast according to the invention
- FIG. 2 is the left hand view of FIG. 1,
- FIG. 3 is a view analogous to FIG. 1, showing a modification
- FIG. 4 is the lef-hand view of FIG. 3,
- FIG. 5 is an enlarged partial view in perspective showing, in the case of FIGS. 3 and 4, the guide means of the whole mobile projector support assembly, with said assembly (not shown) being assumed to be in its lower position,
- FIG. 6 is a partial front view of the device in FIG. 5,
- FIG. 7 is a view in section taken along the line VII- VII in FIG. 6,
- FIG. 8 is an exploded view in perspective of the upper end of the mast in FIGS. 3 and 4, and,
- FIG. 9 is a view on a larger scale and in section taken along line IX-IX in FIG. 6.
- the projectors l are fixed on a support 2 situated at the upper end of a lattice beam 3 constituting the mast proper.
- the mast 3 has, in proximity to its lower end, an axis of articulation 4 which can pivot in the bearings 5 on a pedestal 6.
- the lower end of mast 3, extending beyond axis 4, is provided with a counterweight 7 for balance.
- the mass of the counter-weight is constituted, for example, by dry sand.
- the pedestal 6 is provided with a stop 8 for positioning the mast vertically.
- Means, not shown, are also provided to lock the mast in this vertical position with stop 8 possibly being used advantageously for this purpose.
- the mast is pivoted with the aid of a motor-reducer set, not shown, keyed, for example, at the end of axis 4.
- the pedestal 6 is anchored in a block of concrete supporting the whole apparatus.
- Mast 3 must be constituted by a very rigid beam because the weight of assembly 1 2 is on the order of 600 kilograms and more.
- Projectors 1 are supported by a ring 9, normally situated on the upper part of a tubular mast 10 and capable of being displaced along said mast in order to be brought in proximity to the control platform 11 situated on the upper part of a pedestal 12.
- mast 10 has an axis 13 which can pivot in two horizontal bearings 14 fixedly mounted on platform 11.
- a motorreducer set 15 connected to one end of axis 13, insures the pivoting of the mast.
- ring 9 The displacement of ring 9 is insured by a cable 16, winding, at the level of the platform, on the drum of a winch 17 and then passing inside the mast to the top of the mast where it winds over a pulley 18 and extends outward along said mast and is fixed to the ring 9.
- Conventional means are provided for locking the ring on the upper part of the mast.
- the ring 9 is fixedly connected to a carriage 19 guided on a rail 20 extending along the mast 10.
- Carriage 19 has a U-shaped cross section, with the lateral arms extending perpendicularly to the edges 21 of rail 20 and the guidance thereof being insured on the one hand by rollers 22 and 23 disposed on either side of the wings 24 of said rail, and on the other hand by centering rails 25 disposed according to FIG. 9.
- Carriage 19 is provided with a brake device as follows:
- Said cable 16 is fixed on the median part of a cap 26 which can pivot on a shaft 27, the ends of which are fixedly connected to carriage 19.
- the vanes of cap 26 are linked in rotation, by means of a locking finger 28, to cams 29 which can pivot on shaft 27, and which extend through an opening 30 made in the median part of the carriage 19.
- Springs 31 each fixed by one end to carriage l9 and by the other end to the median part of cap 26, tend to pivot the cams 29 and apply them against the rail 20 (FIG. 7).
- This braking device also offers the advantage of immobilizing the ring 9 with respect to the mast as soon as cable 16 is relaxed and this permits lowering the mast below the horizontal.
- Line 33 feeding the projectors is constituted by a flexible cable fixed at intervals on small carriages 34 which are free in translation.
- Rail 29 is advantageously used to insure guidance of said carriages 34 (FIG. 5).
- the mast is equipped with a limit switch 35 whose trip is influenced by two cams 36 situated at the top and at the bottom of the mast, as shown in FIG. 5.
- a mast for supporting projectors comprising a mast pivotally mounted near its base on a horizontal axis, a guide rail extending along said mast, a carriage moveably mounted on said rail, a ring supporting the projectors and connected to said carriage, a cable connected to said ring, a pulley mounted on the top of said mast and having said cable extending thereover, a shaft extending through said carriage, a cap rotatably mounted on said shaft and connected to said cable, cams rotatably mounted on said shaft, said carriage having an opening with said cam extending therethrough for at times engaging said rail, means connecting said cap and said cams and resilient means tending to pivot said cams against said rail and means for pulling said cable for moving said cams from said rail.
- a mast for supporting projectors comprising a mast, a guide rail extending along said mast, a carriage slideably mounted on said rail, a ring supporting the projectors, a cable, a pulley mounted on said mast and having said cable extending thereover, a shaft on said carriage, a cap pivotally mounted on said shaft and connected to said cable, cams rotatably mounted on said shaft, said carriage having an opening with said cams extending therethrough towards said rail, springs connected to said cap and said mast tending to pivot said cap moving said cams against said rail and pulling said cable.
