Definitions

  • the invention relates to a device for fastening a microwave antenna with a surface reflector on a standpipe, with a holding part attached to the rear of the surface reflector, which is opposite an attachable to the standpipe U-shaped swivel part by means of an adjustable screwing device for adjusting the angle of the antenna by one Axis of rotation is pivotable, which extends horizontally through the mutually parallel interlocking legs of the holding part and the pivoting part perpendicular to the main beam direction of the antenna.
  • Such a device as can be used in particular for holding smaller parabolic antennas for satellite radio reception, is already known from DE-OS 31 27 855.
  • the swivel device is complicated due to the many individual parts (screw connections, mounting brackets for the screw spindles) on the one hand in terms of material requirements and manufacture and on the other hand, in particular with regard to the setting of the elevation angle, complicated to use.
  • an additional manufacturing effort is required because the holder must be attached to the reflector.
  • the holding part can be separated from the pivoting part in this known device; however, loose parts result in the packaging and the assembly effort of the holding device is further increased.
  • the device known from DE-OS 19 56 152 of the above ten Art is because of the high manufacturing costs due to the many screw connections, the required fastening device for connection to the reflector, and the complicated structure of the pivot device with rotatably mounted cross bolt and pinned screw relatively expensive.
  • this version has a large packaging depth because the side parts of the swivel part must be as wide as possible so that a sufficiently large adjustment range of the elevation angle can be reached.
  • the invention has for its object to provide a device of the type mentioned, which is simple and inexpensive to build, has a small packaging size without losing parts and allows fast and permanently safe assembly and adjustability of the elevation angle.
  • the holding part consists of two ribs parallel to one another and to the main beam direction, integral with the surface reflector, as the axis of rotation only a continuous bolt is provided, onto which the swivel part can be locked and that a rib at a distance from Axis of rotation a threaded pin is articulated, on which a nut can be rotated to adjust the elevation angle of the antenna, said nut engaging with an annular bead in a slot of the pivoting part.
  • the device according to the invention can already be produced simply and inexpensively due to the one-piece construction of the holding part and surface reflector and the part-saving, uncomplicated construction of the swivel device. Due to the pivoting part which can be plugged and locked onto the bolt representing the axis of rotation, the assembly is also extremely simple and quick to carry out. In addition, due to the separation of the swivel part with mast fastening clamp from the holding part integral with the surface reflector, the antenna has a small packaging size and no loose parts that can be lost.
  • the adjustment of the elevation is also advantageous angles with extremely little effort, namely only by means of a threaded rod with a nut designed expediently as a manually operable handle knob, without lock nuts, rotatable cross bolts or the like. enables, while still a quick, yet precise and safe angle adjustability is guaranteed.
  • the bolt forming the axis of rotation can also be used as a handle, with which the antenna can be transported very easily by hand, particularly with larger reflector dimensions.
  • an expedient embodiment of the swivel part and bolt is specified, which enables simple assembly without loosening parts (eg screw connections).
  • the swivel part in the case of an embodiment according to claim 2 with the legs between the ribs and clamps
  • the swivel part only needs to be plugged onto the bolt with the key-shaped recesses, which after release by the force of the compression spring slides back into the starting position, in which the swivel part is rotatably attached to the bolt.
  • the one in which the bolt is axially displaced under spring force is generally more favorable.
  • an annular groove possibly as far as possible. conical end faces
  • an equivalent constriction may be provided.
  • the swivel part can be plugged on particularly easily and quickly if the keyhole-shaped recesses have an enlarged section on the open end part which serves as an insertion aid.
  • An embodiment according to claim 6 ensures in a simple manner that the key surfaces are always in the desired angular position.
  • a simple version e.g. a square head and a nose resting thereon may be provided.
  • a design according to claim 7 is more favorable, in which the hook lies in the groove in the operating state and thereby ensures the protection against rotation, while in the assembled state it rests on one of the groove walls (the amount of the desired axial displacement of the Bolzens corresponds) and thereby frees the fitter both hands for further assembly work.
  • the insertion (or removal) of the swivel part onto the (or from the) bolt is particularly simple when the key surfaces are designed according to claim 8, because the bolt is thereby pressed onto the oblique parts by the pressure of the corresponding edge parts of the key-shaped recesses of the legs of the swivel part lateral end faces of the key faces (or in an equivalent part of an annular groove) is automatically moved instead of by hand and causes a forced locking when sliding back automatically.
  • the hook is conveniently always in the groove, so that the bolt is secured against rotation and the key surfaces are always in the correct position.
  • the training described in claim 10 of the invention direction advantageously results in a flawless guidance when setting the elevation in a large angular range and a support of the pivoting part on the ribs of the reflector and, through this increase in the stability of the device, results in flawless adjustability even with large antenna weights and / or wind loads and - together with the measures according to claim 2 - permanent exact adherence to the set elevation angle within very narrow limits.
  • an effective screw connection protection is achieved in a simple and extremely cost-effective manner without additional, possibly lost parts.
  • the attachment of a scale according to claim 15 is particularly expedient for the rapid adjustment of the desired antenna inclination.
  • the mast screw 8 consists of a U-shaped bracket 10 which, with its free arms designed as threaded bolts, passes through the base part 11 of the pivoting part 1 and comprises the standpipe 9, and a counter clamp 12, which is pressed onto the standpipe 9 with wing nuts 13 when the device is mounted becomes.
  • the base part 11 of the swivel part 1 has a V-shaped recess 14 at the upper and lower ends, on the side walls of which the standpipe 9 rests, and in the central region a wide trough-shaped recess 15, at the bottom of which the base part of the bracket 10 rests for its stabilization .
  • the swivel part 1 with the mast screw 8 is separated from the rest of the device, so that the antenna has a minimal packaging size.
  • the bolt 6 passes through central bores of the ribs 3, not visible in the figures, and one clamp clamp 19 each arranged on the inside of the ribs, each of which can be pressed against the ribs 3 by means of two screws 20 and wing nuts 21.
  • the screws 20 have hexagon heads 22, on the one surface of which a nose 23 pressed out of the clamps 19 bears against rotation, so that the screw connections can be handled without tools.
  • One end section of the bolt 6 carries a compression spring 24 which surrounds it closely and which is supported on the one hand on the outer surface of the rib 3 and on the other hand with an end turn of smaller diameter on the outer end face of an annular groove 25 of the bolt 6.
  • a compression spring 24 which surrounds it closely and which is supported on the one hand on the outer surface of the rib 3 and on the other hand with an end turn of smaller diameter on the outer end face of an annular groove 25 of the bolt 6.
  • an equivalent locking ring or a similar device could be provided instead of the groove 25.
  • the other end section of the bolt 6 is designed as a hook 26 angled at 90 ° to the axis D with an approximately rectangular cross section, which is secured against rotation in a through on the outer wall of a Rib 3 integrally formed side walls 27 formed groove 28.
  • the legs 4, 5 of the swivel part 1 each have a keyhole-shaped, open at the beard end recess 29, the circular inner part 30 has a slightly larger diameter than the bolt 6, while the width of the inner beard-shaped section 31 is significantly smaller than the bolt diameter and the outer section 32 is significantly wider as an insertion opening.
  • a slot 33 is provided, in which an annular bead 34 engages in the operating state of the antenna, which is part of a handwheel 35 which can be screwed onto a threaded spindle 36, which at the other end has a tab 37 on one of the screws 20 is articulated.
  • the swivel part 1 is automatically locked in such a way that, when plugging in, the shoulders 41 of the recesses 29 first slide along the inclined end faces 39 of the incisions of the bolt 6 and move it against the force of the spring 24 to such an extent that the narrow section 31 of the recesses 29 can slide past the key faces 38 until the inner circular part 30 comprises the bolt 6, which then moves axially outwards by the spring force to such an extent that the pivot part 1 can be rotated about the axis D and is firmly connected to the ribs 3 in the radial direction .
  • the linear (and not punctiform) abutment of the shoulders 41 on the inclined end faces 39 ensures that the sliding operation is always safe.
