Definitions

  • ABSTRACT A standard or pole for supporting light fittings is disclosed which is designed with a view to yielding when being hit by motor cars, so as to be less dangerous.
  • the pole which is tubular substantially over its entire length is provided with a foot comprising downwardly diverging struts or tongues fastened to a ground base.
  • Said tongues may be formed by splitting the lower end of a tubular pole section or they may be formed by separate rods welded to the outside of the lower end of the lowermost tubular pole section.
  • Preferably the lower ends of said struts or tongues are attached to a circular foot plate secured to the ground base.
  • the object of the present invention is to provide a standard or pole which retains most of the good qualities of the tubular design but is yielding in a higher degree to horizontal forces applied near its base, so that the pole, instead of abruptly stopping a colliding car, is subjected to considerable deformation andhence offers a prolonged and gradually growing resistance, so that retardation of the colliding car is reduced.
  • a pole or standard for supporting light fittings which is tubular substantially over its entire length and comprises a foot formed by a plurality of tongues or struts the upper ends of which are united to the lower end of the tubular part of the pole the tongues or struts extending therefrom at an angle to the vertical in a downward and outward direction, and in a symmetrical arrangement.
  • FIG. '1 is a side view of a first embodiment of a pole
  • FIG. 2 shows the part of FIG. 1 framed chain-dotted, on an enlarged scale
  • FIG. 3 is a cross-sectional view taken from the line III-III of FIG. 2,
  • FIGS. 4, 5, 6 and 7 are side views, of four further embodiments of the pole foot.
  • the pole shown in FIG. 1 is composed of three cylin drical tubes 11, 13, of lessening diameter, and an arm 17 for supporting alight fitting (not shown).
  • the invention is also applicable to other known kinds of tubular poles, e.g., those comprising a single cylindrical or tapering tube with or without a hanger arm.
  • the tubes are of a circular cross-section, but other, e.g., polygonal cross-sections are possible.
  • the lower end of the lowermost pole section 11 is slit along axially extending lines to form four equal tongues 19, 21, 23, 25, having the same width over their entire lengths. These tongues are spread apart by introducing a conical mandrel into the end of the pole tube. At the same time the tongues may be shaped, their arcuate cross-sections being flattened to a curvature of a greater radius. At their lower ends the tongues are welded to the circumference of a circular foot plate 27. Holes 29 are providedtherein for the insertion of bolts, by which the pole may be secured to a ground base 31 of known kind.
  • the tongues form a foot integral with the lowermost pole tube 11 and widening downwardly.
  • the slits offers about the same resistance to bending forces as the upper part of tube 11 in respect of horizontally directed forces.
  • the separate tongues the cross-section of each of which is very small in comparison to their length are weak and are easily bent inwardly, if they are hit by a horizontally moving object between their ends. A colliding car first hits one of them and then more, so that the resistance grows as the deformation proceeds in dependence on the violence of the shock.
  • the tongues should be of a length of between 1 and 2 metres. Their inclination to the vertical is preferably not more than 10, and the diameter of the foot plate is chosen to be 2 to 3 times as great as the diameter of the tube 11.
  • the pole foot 33 forms a separate unit and consists of a tube which is split over the greater part of its length and the upper end of which carries an annular flange 34, by means of which the foot can be attached to the lower end of a tu' bular pole of a known design.
  • the tongues of the pole foot forming diverging struts have their lower ends attached to a circular foot plate 27 which may be bolted to a ground base 31.
  • FIG. 5 shows a pole foot similar to that of FIG. 4, but the foot plate is omitted and instead, the lower ends 35 of the tongues are welded or screwed to the outside of the upper portion of a cylindrical tubular base 37.
  • the tongues 36 are made integral with the base 37.
  • the base consists of a steel tube of a-considerably'greater diameter than that of the pole above the foot, and broad slits are cut out between the tongues, which are then bent together and attached to the outside of the tubular pole, eg by welding.
  • the tongues are made of separate rods 39, the upper ends of which are welded to the outside of the tubular pole and'their lower ends to a foot plate.
  • FIG. 7 the form of FIG. 6 is modified by connecting the tongues by a lattice-work of cross stays 41 which should be so constructed that it increases the resistance of the props to buckling caused bylongitudinal forces, without greatly increasing their resistance to horizontal shocks.
  • the embodiments shown may be modified in other respects, particularly as to the number of tongues or struts of the pole foot. This number may be as low as two or three, and as high as five or six.
  • a pole or standard for supporting light fittings comprising an upper structure forming a major portion of the length of the pole or standard, said upper structure including a central vertical tubular structure, and a foot formed of a plurality of spaced apart tongues or strutshaving upper ends terminating at and united to the lower end of saidtubular structure and having lower ends connected to a common base which is of greater horizontal dimension than said tubular structure, said tongues or struts being; arranged symmetrically with respect to the axis of said tubular structure and extending downwardly beyond the lower end of the latter and outwardly, whereby said tongues or struts vsupport said tubular structure from said base and provide an assembly which is yieldable to horizontal forces occurring on collision of a vehicle: with said tongues or struts.
