Definitions

  • the starting point of the invention is a device for holding a parabolic antenna with the features specified in the preamble of claim 1. It is known to attach two parallel, vertical cheeks to the rear of the parabolic antenna and to pivotally connect them to another pair of parallel cheeks, which are part of a holder which is provided for fastening to a stand or antenna mast for the parabolic antenna.
  • the cheeks of the parabolic antenna are connected to each other by a horizontal screw bolt. This bolt is provided near the top of the cheeks.
  • two elongated holes are provided in one pair of cheeks below the swivel axis, which are designed in the shape of a circular arc and have their center of curvature on the swivel axis.
  • Two clamping screws extend through these elongated holes in threaded holes in the other two cheeks. By tightening these clamping screws, the parabolic antenna can be fixed on the cheeks of the bracket with a pre-selectable inclination.
  • the known device has the disadvantage that the parabolic antenna cannot be easily mounted on the stand.
  • the connection between the dish and their mounting is so difficult that it can be carried out on the ground, but hardly on an antenna mast or on a sloping roof. Rather, in such locations it is necessary to provide the parabolic antenna with its holder on the ground first and then to fix this holder together with the attached parabolic antenna to the stand provided for this purpose - as a rule this is a standpipe; but the latter is also extremely laborious given the size and weight of the parabolic antenna.
  • the invention has for its object to improve and simplify a device for holding a parabolic antenna in such a way that even at locations on a sloping roof or on an antenna mast first attach a bracket to an antenna stand and then without much effort the parabolic antenna in it Bracket can use.
  • the parabolic antenna can be initially installed without regard to the adjustment of its inclination in the bracket previously attached to the stand of the antenna, which the cheeks with the includes two sloping slots. This is possible with one hand, and then the parabolic antenna hangs captively in the oblique slots of the holder. Secured in this way, the inclination of the parabolic antenna can then be adjusted and fixed using the clamping screws provided.
  • the parabolic antenna To adjust the inclination of the parabolic antenna, there is preferably a part on the holder with a threaded hole into which an externally threaded rod is screwed, the tip of which abuts against the rear of the parabolic antenna.
  • a trough is provided there so that the position of the tip on the back of the parabolic antenna is clearly defined. This trough lies below the swivel axis.
  • the part with the internal thread on the holder, in which the rod with its external thread is inserted is expediently a nut which is attached to the holder by means of a cage so as to be non-rotatable but limited in its inclination, so that the rod has a pivoting movement the parabolic antenna can perform the following pivoting movement.
  • the parabolic antenna comprises a reflector flange 1 and a reflector 1a and a coaxial housing 2 arranged on its front side, which contains the excitation system of the antenna.
  • On the back of the reflector flange 1 are the signal outputs 3 and 4 of the excitation system and two mirror-image cheeks 5 and 6 of the same design and arrangement, which are arranged symmetrically with respect to the axis 7 of the reflector.
  • a threaded hole 8 is provided in the vicinity of the upper edge and the lower edge of the two cheeks 5 and 6.
  • each cheek carries a pin 9 projecting outwards in the middle between the threaded bores 8, exactly at the axis 7 of the reflector 1a.
  • the two coaxial pins 9 define the pivot axis of the reflector flange 1.
  • the holder 10, to which the reflector flange 1 is to be fastened comprises a base plate 11 and two cheeks 12 and 13 projecting at right angles therefrom and having the same mirror image, the spacing of which is just such that the two cheeks 5 and 6 of the reflector flange 1 can be inserted between them.
  • the two cheeks 12 and 13 each have a slot 14 which runs obliquely from top to bottom and is open at the top, which is just wide enough for the pin 9 to slide therein.
  • the slots 14 are rounded in a circular arc at their lower end, so that the reflector flange 1 suspended in the slots 14 with the pins 9 can be pivoted about the axis formed by the pins 9 (FIG. 2).
  • a rod 19 is provided, which carries on part of its length an external thread 20, with which it is screwed into a nut 21, which is mounted in a cage 22 which is inserted into a hole in the base plate 11 of the holder 10.
  • the tip 23 of the rod rests in a deep recess 24, which is molded onto the back of the reflector flange 1.
  • a further arcuate elongated hole 25 is provided above the elongated hole 16, which reveals the view of a scale line 26, which is attached to the cheek 5 behind the reflector flange and allows the reading of an angular scale 27, which runs along the edge of the elongated hole 25 is attached to the cheek 13.
  • this inclination is fixed by screwing the clamping screws 28 into the threaded bores 8.
