Partition structures and frame elements therefor

A connectible frame element for a partition structure comprising a rigid rectangular frame formed by two opposing side rails and upper and lower horizontal rails at least one of which is of rectangular channel section with the opening of the channel facing outwards, and an abutment shoulder extending inwardly into the channel on each channel side;

• and a frame interconnector comprising a resiliently compressible channel section member dimensioned to be introduced in inverted position within said horizontal channel section rail and having an outwardly extending engaging rib on the free end of each channel side, said rib in a normal position engaging respective abutment shoulders of the channel of the rail to prevent withdrawal from the rail and the interconnector member being laterally compressible to allow said rib to move past the shoulders and allow introduction of the interconnector;
• and releasable connector means for connecting the interconnector member to the channel rail of a second frame element similar to the first-mentioned frame element when superimposed therein;
• and wherein said frame elements each have an edge flange extending laterally outwardly from the free end of the channel side of each channel rail, the edge flanges of said second frame element seating on the edge flanges of the first-mentioned frame element.

A corner partition structure comprising first and second rigid rectangular frame elements each having at least one side rail formed with an opening receiving a threaded connector member;

• and a corner connector comprising a short length of an extrusion which is multiply lobed in cross section, each lobe having a channel section recess with serrated inner sides, the threaded connector of each frame element threadedly engaging a respective serrated recess.

A cable housing frame element for a partition structure comprising a rigid rectangular frame formed by two opposing side rails and upper and lower horizontal rails at least one of which is formed with a channel section recess opening toward the interior of the frame element and having a projection extending inwardly from each side thereof;

• and an extruded resilient plastics material cable carrier having in cross section an upper end with laterally outwardly and downwardly extending wings each formed with a shoulder which in a normal position snap couples in the recess and engages the upper side of a respective one of said projections to resist withdrawal, and each wing extending outwardly from the recess to allow the wings to be grasped and laterally compressed to allow withdrawal from the recess, and a lower portion having an upwardly open channel for receiving electrical cables.

A ceiling connectible frame element for a partition structure comprising in combination a rigid rectangular frame formed by two opposing side rails and upper and lower horizontal rails at least one of which is formed with a channel section recess opening to the outer side of the frame, and a resilient channel section ceiling connector member having a flange extending inwardly from each channel side whereby the flanges can resiliently grip the outer sides of a rectangular section ceiling bar intended to be secured to the ceiling at the point where the frame element is to be connected to the ceiling, and parallel lower side surfaces which snugly engage the inner sides of the channel of said horizontal rail, so that the connector can be slipped downwardly relative to the ceiling bar from an upper assembly position allowing the channel of said one rail of the frame element to be positioned under the connector member to a lower anchoring position wherein said side surfaces engage on the sides of the channel of said horizontal rail.

A base frame element for a partition structure comprising a rigid rectangular frame formed from opposing side rails and upper and lower horizontal rails, the lower rail provided at longitudinally spaced points with leveller means comprising a threaded opening adjacent the lower side of the rail, a threaded shank engaging said opening and having a free end adjacent the lower side of the rail and a tool engaging head having planar vertically extending tool engaging surfaces disposed above the opening wherein said lower rail has a channel section recess facing toward the outer side of the frame element and having a projection extending inwardly from each side, and said threaded opening is provided by a flat sided threaded member non-rotatably located in the recess with its flat sides engaging the sides of the channel.
