ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a collapsible stage or like structure and relates particularly but not exclusively to such in the stage renting arts.
DESCRIPTION OF PRIOR ART
Hitherto, in the stage renting arts, it has been common to provide portable stages for use at various venues. Typically, the stages are collapsible and or dismountable in order to provide for easy transport and economies of space in a transport vehicle. Generally, the dismantling and subsequent assembly processes are quite laborious.
BRIEF SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a collapsible stage or like structure which is economic yet functional.
Therefore, according to a first broad aspect of the present invention there may be provided a collapsible stage or like structure having a floor. The floor comprises first plannar and second plannar outer wings and an intermediate plannar section. The first and second outer wings are swingably connected relative to intermediate section so that both first and second outer wings can swing upwardly from a plane where they are substantially co-plannar with said intermediate section, where they collectively form a stage or like structure floor, to a collapsed position where both first and second outer wings are generally parallel to one another and extend upright.
In this broad aspect, the intermediate section has ground engaging means thereon to permit rolling or sliding movement of a collapsed stage or like structure.
Also in this broad aspect there are: (a) a first pair of retractable legs swingably connected with an underside of first outer wing adjacent one side of intermediate section, and (b) a second pair of retractable legs swingably connected with an underside of second outer wing adjacent the otherside of intermediate section.
Further in this broad aspect, guide means are attached to intermediate section guiding each of retractable legs. Thus feet means on legs will be below ground engaging means when first and second outer wings are swung, so that they are substantially co-plannar with intermediate section and will be above ground engaging means when first and second outer wings are swung upwardly to collapsed position.
Still further in this broad aspect, the outermost regions of first and second outer wings each have further leg means swingably connected thereto. The leg means can be swung from collapsed positions where they extend substantially parallel to the planes of the respective first and second outer wings, to erect positions where they extend substantially perpendicular to the planes of the respective said first and said second outer wings.
It is particularly preferred that first pair of retractable legs be guided by guide means so they are always inclined relative to the plane of intermediate section. With this construction first pair of retractable legs crosses second pair underneath said intermediate section, so that feet means of first pair are disposed, when extended, to be closer to the side of intermediate section to which second outer wing is swingably attached than to the side to which first outer wing attaches. Thus feet of said second pair are disposed, when extended, to be closer to the side of intermediate section to which first outer wing is swingably attached than to the side to which second outer wing is attached.
It is also particularly preferred that there be link means swingably connected with further leg means and with trolley means which will cause the further leg means to swing to the collapsed positions when first and said second outer wings are swung to the collapsed position. Thus causes further leg means to swing to erect positions when first and second outer wings are swung to be substantially co-plannar with intermediate section.
