BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention relates to a column and particularly to that type of column having a base section and a tiltable section, the tiltable section being hinged adjacent the top of the base section. The provision of a tiltable section is normally for the purpose of facilitating the cleaning of the lamp or other unit carried at the top of the tiltable section. Such columns are particularly useful in situations where it would not be possible to clean the lamp or other unit at the top of the tiltable section by conventional means.
One of the problems with such columns has been that their appearance is not normally so elegant as normal columns which do not include a tiltable section.
SUMMARY OF THE INVENTION
The present invention provides a column having a base section and a tiltable section, the tiltable section being hinged adjacent the top of the base section intermediate its ends by hinge means whereby, when the tiltable section is in the normal upright position substantially colinear with the base section, the hinge means is entirely within the base and tiltable section.
Thus the hinge is not visible as in normal constructions and this makes for a more elegant column. Furthermore, the hinge will not be exposed to the weather and this further overcomes problems with the conventional hingeing arrangement.
The hinge means may preferably take the form of an arm member which is pivotally connected to the base section and pivotally connected to the tiltable section. The arm is preferably not straight. In a preferred arrangement there may be provided two similar arms arranged parallel to one another and side by side. This improves the structural integrity of the joint between the two sections.
The arm may take a form such that the tiltable section may be tilted from a position in which it is generally colinear with the base section in its normal position through approximately 180.degree. to a position in which it is parallel to and alongside the base section and upside down with respect to its normal position. Alternatively the arm may be arranged such that the tiltable section may be tilted from a position in which it is generally colinear with the base section in its normal position, and through an angle less than 180.degree., for example approximately 135.degree. to a position in which the upper end of the tiltable section is adjacent the ground. In this case it is necessary to provide means for holding the tiltable section in such a position and this may be provided by means of a wire which extends from the lower end of the base section to the tiltable section.
When the tiltable section is upright in its normal position, the two sections preferably form a continuation of one another, that is, the two sections have the same cross section where they meet and, where applicable, have the same taper.
BRIEF DESCRIPTION OF THE DRAWING
Preferred arrangements of the invention will now be described by way of example only and with reference to the accompanying drawings in which:
FIG. 1 is a diagrammatic perspective view, partially in section, of a column according to the invention in its normal position,
FIG. 2 is the column of FIG. 1 shown in a second position in which the tiltable section has been pivoted through approximately 180.degree.,
FIG. 3 is an enlarged, vertical sectional view of the joint between the base section and tiltable section of the column of FIG. 1 with a modified arm, the position shown corresponding to FIG. 1,
FIG. 4 is a view of the parts of FIG. 3 but in a position corresponding to that of FIG. 2, and,
FIG. 5 is a diagrammatic perspective view of an alternative arrangement of column.
DETAILED DESCRIPTION
Referring to FIG. 1 the column 10 comprises a base section 11 and a tiltable section 12. In the present embodiment the base section and tiltable section are each of the same cross section and are formed of folded sheet metal. The cross section is octagonal but other cross sections would of course be suitable.
The base section 11 is mounted uprightly in the
