An elongate member (10) is provided having a first elongate portion (12), a second elongate portion (14) and an interconnecting joint (16). The interconnecting joint (16) is disposed at an acute angle to the first elongate portion (12) and rotation of the second elongate portion (14) about the interconnecting joint (16) allows a user access to an article (11) located at the upper end of the second elongate portion (14).
An elongate member for locating an article remote from a base position, characterised in that the elongate member comprises an inner elongate portion having a longitudinal axis, the inner elongate portion extending, in use, from the base position, an outer elongate portion, the outer elongate portion being arranged to receive the article, and means for interconnecting the inner elongate portion to the outer elongate portion so as to permit relative rotation of the inner and outer portions about an axis of rotation, the axis of rotation being disposed at an acute angle relative to the longitudinal axis of the inner elongate portion, the means for interconnecting the inner elongate portion to the outer elongate portion including a first member connected to the inner elongate portion, a second member connected to the outer elongate portion, a third member, and means for connecting adjustably the third member to the first member, the second member being located between the first member and the third member, the means for connecting adjustably the third member to the first member comprising at least one bolt arranged to pass through the first member and the third member, the bolt having an associated nut arranged such that tightening of the nut on the bolt causes the first member and the third member to apply a clamping force to the second member to prevent the relative rotation of the inner and outer elongate portions, and that partial release of the nut from the bolt causes the third member to be partially disengaged from the first and second members to permit the relative rotation of the inner and outer elongate portions, wherein the article comprises a light source and further comprising wires passing through the means for interconnecting for supplying electrical power to the light source.

The invention relates to an elongate member for locating an article in a location remote from a base plane.
It is known to provide an elongate member in the form of a pole for locating an article such as a light source in a location upwardly of and remote from a base position such as on the ground or an elevated platform. Such poles are commonly used in processing plants and refineries for illuminating the plant at night.
At present, one method of servicing or replacing the articles is by incorporating into the pole means for selectively permitting the pole to pivot about a substantially horizontal axis. In this way, the pole may be manually manipulated by a user to bring a remote end of the pole and thereby the article to a location sufficiently close to the user.
The present invention will now be described, by way of example only, with reference to the accompanying drawings, in which:
FIG. 1 is a diagrammatic perspective view of an elongate member in accordance with the present invention;
FIG. 2 is a diagrammatic perspective view of a portion of the elongate member shown in FIG. 1;
Referring to the drawings, there is shown an elongate member 10 for locating an article such as a light source 11 in a location upwardly of and remote from a base position 13 which may be on the ground or on an elevated platform.
In this example, the article will be taken to be a light source 11. However, it will be appreciated that other articles are envisaged, for example a flag or an antenna.
The elongate member 10 includes a first elongate portion 12, a second elongate portion 14 and interconnecting means 16 which is disposed between the first elongate portion 12 and the second elongate portion 14.
