DESCRIPTION:
BRIEF SUMMARY
This invention relates to temporary or collapsible structures which may be used for example at indoor or outdoor sites or other places where an attractive short-term shelter is required.
BACKGROUND TO THE INVENTION
There are of course many types of tent-like structures used for temporary shelter. These range from simple rectangular steel frames loosely hung with canvas to the more elaborate structures. Such known apparatus however have the disadvantage of requiring a large number of separate parts which have to assembled on site. This of course is time consuming and requires the employment of expensive skilled labour. My co-pending Australian Application No. 52329/93 discloses arrangements which enables relative ease of assembly.
OBJECT OF THE INVENTION
It is therefore an object of this invention to ameliorate the aforementioned disadvantages and at the very least to provide an alternative to known arrangements.
DISCLOSURE OF THE INVENTION
Accordingly a relocatable collapsible support structure for a cover means is disclosed, said structure comprising at least three apex poles with first ends thereof pivotally connected together so that in use said apex poles are movable between a raised configuration in which the second opposite ends thereof extend outwardly in different directions to create a pyramid shaped frame and a collapsed configuration, and pairs of perimeter poles with each pair forming an inverted V between said opposite ends of adjacent apex poles when in said raised configuration so as to form together with said apex poles the aforesaid pyramid shaped frame and the apex poles and perimeter poles being pivotally connected so as to fold together into close substantially parallel positions when in the collapsed configuration and bracket means linking said apex poles intermediate said first and second ends said bracket means comprising braces which extend between and are pivotally attached to each apex pole and a central connector whereby the central connector may be pushed towards said first ends of said apex poles to obtain said raised configuration or away from said first ends to obtain said collapsed configuration and the bracket means including locking means for limiting movement of the central connector toward said first ends when in said raised configuration, wherein the connected perimeter and apex poles are secured in an open position by a releasably operated telescopic brace means pivotally connected therebetween.
According to another aspect there is disclosed a collapsible support structure for a cover means, said structure comprising at least three apex poles with first ends pivotally connected together so that in use said poles are moveable between a raised configuration in which the second opposite ends extend outwardly in different directions to create a pyramid shaped frame and a collapsed configuration, and pairs of perimeter poles with each pair forming an inverted V between said opposite ends of adjacent apex poles when in said raised configuration and bracket means comprising struts which extend between and are pivotally attached to respective apex poles intermediate their ends and a central flange means whereby the first connected ends of said apex poles and said central flange means may be pushed toward each other to obtain said raised configuration or pushed apart to obtain said collapsed configuration and said apex poles and perimeter poles being pivotally connected so as to fold together into close substantially parallel positions when in said collapsed configuration, wherein said cover means is attached to said support by hook and loop means.
BRIEF DESCRIPTION OF THE DRAWINGS
The currently preferred form of this invention will now be described with reference to the attached drawings in which:
FIG. 1 is a perspective view of a structure according to this concept in the raised configuration,
FIG. 2 is a detailed perspective view of a connecting bracket for connecting the ends of the apex poles together,
FIG. 3 is a cutaway side view of a mechanism for extending
