Definitions

  • the present invention relates to antenna tower assemblies or masts and the like, being particularly directed to lighweight structures of the telescoping type, readily raised and lowered in a portable manner.
  • An object of the present invention is to provide a novel telescoping antenna tower assembly that in large measure obviates the above-discussed problems and provides a lightweight, structurally sound tower or mast assembly emboding many common or identical lightweight parts and simple raising and lowering mechanism, enabling portability and ease of operation.
  • a telescoping antenna tower assembly comprising a plurality of hollow equilateral triangular aluminium tubular sections bounding successively diminishing areas, one nested within the other(s) in parallel longitudinal coaxial relationship, sliding means disposed between the successive tubular sections to permit sliding longitudinal axial relative movement, pulley means mounted on the tubular sections, and winch means disposed near the bottom of the outer tubular section and connected with a cable link longitudinally harnessed over the pulley means to permit raising and lowering of the tubular sections by the cable in order to erect and lower the tower, characterised in that said sliding means is in the form of guide rollers disposed at the corners of the sections, said cable link being disposed within said sections and that a retraction cable is connected within the sections between said winch means and that inner tubular section which forms the top of the tower for applying a pulling force to lower the tower.
  • the mast or tower structure of the invention is shown constructed of a plurality of hollow equilateral triangular aluminium or similar thin-walled tubular sections 1, 2, 3, 4, 5, .... enclosing successively diminishing areas (for structural rigidity), one nested within the other(s) in parallel longitudinal successive coaxial relationship.
  • the tubes are preferably formed of similar aluminium sheet sections S, Fig. 4, bolted, swedged or otherwise edge-secured at B to similar extruded aluminum corner brackets 5'; but the embodiment of Figs. 2A-B and 3 are shown for illustrative purposes as having extruded integral tubular sides.
  • a pair of externally mounted upper and lower pulley wheels P are pairs of externally mounted upper and lower pulley wheels P, more particularly shown in Figs. 2A and 2B, receiving a cable harness C from a winch W (Figs. 1B and 3) preferably disposed at the bottom of the outer tube 1 for ready hand, foot-pedal or other operation.
  • the cable harness is designed to enable the tubular sections to be elevated one within the other, along rollers R in the corner, Fig. 3, for erection of the tower, and also for positive cable control in lowering the same.
  • FIG. 1B A suitable cable harness arrangement is shown schematically in Fig. 1B, and portions in Figs. 2A and 2B.
  • a retraction cable 6, Fig. 1B is provided. This consists of a cable connected from the lower end of the uppermost section 5, extending directly downward to a sheave in the base of lowermost section 1, and thence to a drum on the winch W.
  • a satisfactory telescoping, mast or tower of this type has been constructed with the following section dimensions:
  • the sheet walls of the triangular tubular members may be apertured as by punched holes H, the inner punching of which adds structural reinforcement, or by other perforations or lattice structures.
  • the inner tubular sections may initially be raised together before telescopically raising the successive inner tubes to successively higher elevation, and further modifications will also occur to those skilled in this art, and such being considered to fall within the spirit and scope of the invention as defined in the appended claims.

  1. Teleskopartige Antennenmastanordnung mit einer Vielzahl von Abschnitten (1, 2, 3, 4, 5), die jeweils von gleichseitigen dreieckförmigen Aluminiumrohrabschnitten mit schrittweise abnehmendem Querschnitt gebildet und ineinander in paralleler und koaxialer Anordnung vorgesehen sind, mit Gleitmittel (R), die zwischen den aufeinanderfolgenden Rohrabschnitten (1, 2, 3, 4) vorgesehen sind, um eine gleitende axiale Relativbewegung zu ermöglichen, mit Rollenmitteln (P), die an den Rohrabschnitten montiert sind, sowie mit Windenmitteln (W), die in der Nähe des Bodens des äußeren Rohrabschnittes (1) vorgesehen sind und mit einem Verbindungskabel (C) verbunden sind, welches in Längsrichtung derart über die Rollenmittel (P) geführt ist, um ein Anheben und Absenken der Rohrabschnitte (1, 2, 3, 4, 5) mit Hilfe des Kabels zum Aufrichten und Absenken des Mastes zu ermöglichen, dadurch gekennzeichnet, daß die erwähnten Gleitmittel Führungsrollen (R) sind, die an den Ecken der Rohrabschnitte (1, 2, 3, 4, 5) vorgesehen sind, daß das Verbindungskabel (C) innerhalb der Abschnitte (1, 2, 3, 4, 5) vorgesehen ist, und daß ein Kabel (6) zum Einziehen innerhalb der Abschnitte (1, 2, 3, 4, 5) mit den Windenmittels (W) und mit dem die Spitze des Mastes bildenden inneren Abschnitt (5) verbunden ist, um eine Zugkraft zum Absenken des Mastes zu erzeugen.
  2. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Rohrabschnitte aus ähnlichen dünnen ebenen Aluminiumzuschnitten hergestellt sind, die an ihren Kanten in ähnlichen, extrudierten Aluminiumeckabschnitten (5') gehalten sind.
  3. Anordnung nach Anspruch 2, dadurch gekennzeichnet, daß die Zuschnitte (S) für ein geringes Gewicht und bei struktureller Versteifung perforiert sind.
  4. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß die Scheibenmittel (P) ein Paar bestehend aus oberen und unteren Rollen besitzen, die nahe einer Ecke außerhalb des jeweiligen Rohrabschnittes angeordnet sind.
  5. Anordnung nach Anspruch 1, dadurch gekennzeichnet, daß eine Antenne (A) innerhalb des innersten Rohres (5) angeordnet ist, um mit diesem angehoben und abgesenkt zu werden.
