DESCRIPTION:
BRIEF SUMMARY
This invention relates to a space divider and in particular it relates to a space divider of the type already commonly known which comprise members which can be arranged on a floor and generally are self-supporting, using a series of panels which can be positioned in a manner to have the required stability and which are joined together by joining members which allow connection of panels either in line or at angles to a panel these members conveniently comprising plates with pins projecting therefrom which engage apertures in the panels which are to be joined, at least two pins engaging each panel to give the required stability and to allow joining in different ways.
One of the problems with space dividers of this type is that their construction is generally of wood with fabric covering and while the panels are satisfactory in that they can be constructed to have good acoustic properties, their construction as used heretofore generally does not render them fire-proof and therefore not acceptable under some conditions where high fire ratings must be achieved.
Reference may be had to my earlier inventions which related generally to space dividers, see Australian Registered Design No. 65423 and British Letters Patent No. 1600990 and Australian Patent Application No. 26628/84.
It is the object of this invention to provide space dividers comprising panels so arranged that adequate fire resistance can be obtained in a highly effective form of space divider which is both durable and of economical construction and which can be assembled in a ready manner to produce the individual panels which form such space divider.
The panel according to this invention is constructed chiefly of non-inflammable material and utilises side walls with acoustic characteristics spaced apart a required distance and held by upper and lower lock members, the covering of the panel, such as a covering of wool fabric or the like, being formed independently of the panel and drawn over the panel preferably to allow removal of the cover if this is required for cleaning or other purposes, the panel preferably having a skirting member which also forms the electrical conduit means and means to allow the panel to be positioned and located in position.
The actual construction of such a panel can be somewhat varied but to enable the nautre of the invention to be fully appreciated a preferred embodiment thereof will now be described with reference to the accompanying drawings in which:
FIG. 1 is an exploded part sectional perspective view of the components which make up the panel but omitting the fabric or similar covering,
FIG. 2 is a fragmentary perspective view of a portion of the panel showing the main support members of the panel,
FIG. 3 is an enlarged fragmentary cross section of the panel showing the position of the fabric or similar cover over the members of the panel, and
FIG. 4 is a part sectional view of the main frame of the panel showing the fabric cover being pulled into position over it prior to tensioning the cover.
The panel has a first side wall 1 which is constructed to have a series of apertures 2 through it for acoustic purposes and is of generally channel shaped cross section having two end portions 3 turned at right angle to the face of the wall formed by the panel and having a series of intersecting stiffeners 4 and 5 of a dimension to fit neatly into the space formed by the end portions 3.
This construction of the first side wall then forms a series of cavities 6 into which acoustic bats 7 are placed and these are held in place by a second wall 8 also having inturned end portions 9 but the second wall 8 is of slightly greater width than the first side wall 1 so that the inturned end portions of the first side wall lie against the inturned end portions of the second side wall so that the second side wall forms, as it were, a cover member enclosing the cavity 6 and thus confining the acoustic bats 7, this second side wall also having apertures 2 through it to give the necessary acoustic assembly.
The first side wall 1 and the se
