Definitions

  • This invention relates to improvements in columns of the type to support street lighting, flood lighting flags and similar equipment which may require maintenance from time to time according to the precharacterizing part of claim 1.
  • Both Australian Patent Specification Nos. 292033 and 494746 describe columns comprising a base section and an upper section, the upper section being connected to the base section by means of a hinge pin so that said upper section can be raised or lowered whilst the two sections are aligned on the vertical longitudinal axis and so that the upper section can be rotated about said hinge pins whilst in the raised position from the vertical to a substantially horizontal position to allow access to any equipment mounted on or adjacent the upper end of the upper section.
  • Both mechanisms require manual manipulation of part of the mechanism at some stage during their operation.
  • the eccentrically mounted hinge pin in Australian Patent Specification No. 292033 has to be rotated manually by a key 5 whereas in the mechanism of Australian Patent Specification No. 494746 support plate 8 has to be rotated manually.
  • DE-A-2 319 877 describes a column comprising a base section and an upper section, said upper section being able to be raised or lowered with respect to the base section whilst the two sections are aligned on the vertical longitudinal axis and said upper section being able to be rotated about a horizontal transverse axis whilst in the raised position, and a hinge pin secured diametrically opposed elongated slots in the base section.
  • a column comprising a base section and an upper section, said upper section being able to be raised or lowered with respect to the base section whilst the two sections are aligned on the vertical longitudinal axis and said upper section being able to be rotated about a horizontal transverse axis whilst in the raised position, and a hinge pin connected to said upper section engaging diametrically opposed elongated slots in the base section, characterised in that there is provided a hanger pivotally mounted within the base sections with its lower end located adjacent the hinge pin, said lower end being provided with means to automatically engage the hinge pin when the upper section is raised and lock said upper section in the raised position and means provided on said upper section and adapted to act on said hanger to disengage the said hanger from the hinge pin when the upper section is rotated back to its vertical position.
  • the hanger is fixed to a pivot pin which is supporting a pair of opposed slots in the upper end of the base section so that the hanger within the upper end of the base section with its lower portion bearing against the hinge pin when the upper section is in the lowered position and the means for automatically engaging the hinge pin comprises a cut away portion formed adjacent the lower end of the hanger.
  • the column comprises a base section 11 and an upper section 12 both of tubular cross-section.
  • the bottom of the base section is provided with a base plate 13 which is adapted to be bolted or otherwise secured to a suitable foundation.
  • the lower end of the upper section surmounts the the upper end of the base section and is partly cut away to form a cap or skirt portion 14 which is secured to a transverse hinge pin 15 which passes through diametrically opposed elongated slots 16 in the base section.
  • the base section is provided with a tubular passage 17 through which a bolt 18 (see Figs. 2 and 3) maybe passed to connect one end of a hydraulic ram such as that indicated at 19 in Figs. 2 and 3 to be attached thereto.
  • the upper section is also provided with a tubular passage 20 to receive a bolt 21 for attaching the other end of the hydraulic ram 19.
  • a pair of hangers 22 are suspended from a pin 23 supported in diametrically opposed slots 24 in the upper end of the base section.
  • the lower end of each of the hangers is provided with a cut away portion 25 which is adapted to engage the hinge pin 15 when the upper section is in the raised position as is seen in Fig. 2.
  • a central lug 26 projecting upwardly from the pin 23 is provided with a flapper 27 pivotally mounted thereon and projecting to one side and being held in a substantially horizontal position by a stop 28.
  • the upper section is provided with a lug 29 through which a bolt 30 is passed so that its inner end can contact the flapper 27. In the closed position shown in Fig. 1 of the drawings the cap or skirt 14 sets over the upper end of the base section to hold the upper section vertical and the lower end of the hangers 22 lie against the hinge pin 15.
  • a hydraulic ram 19 is attached between the upper section and the base section as is shown in Figs. 2 and 3 and the ram operated to raise the upper section of the column with respect to the base section.
  • the hinge pin 15 slides upwardly past the hangers until it engages in the cut away portions 25 in which position the upper section is locked against both raising and lowering along the vertical longitudinal axis.
  • the operation of the hydraulic ram is then reversed.
  • the upper section of the column rotates about the hinge pin 15 as is indicated in Fig. 3.
  • the ram is operated to rotate the upper section of the pole to the vertical position.
  • the inner end of the bolt 30 bears against the flapper 27 and causes the lower ends of the hangers 22 to rotate clear of the hinge pin 15 thus allowing the upper section of the pole to drop down into the locked position as shown in Fig. 1.
  • the mechanism is completely automatic and does not require any manual manipulation at any stage of its operation. Also being housed within the column it is protected against vandalism and the effects of the weather.
