Corner member, corner assembly, construction kit and rectangular structure

A corner bracket assembly, the corner bracket assembly comprising a single extrusion corner bracket;

• an at least one nut;
• an at least one bolt;
• and an at least one clamping block or clamping strip, the single extrusion corner bracket including:
• a length;
• a body and a pair of wings extending the length and defining an outer right angle and a pair of inner right angles, the inner right angles being normal to each other, each inner right angle having a first face and a second face;
• and a slot within the body and extending the length, the slot including an elongate opening defined by a proximal edge of each first face, the elongate opening extending the length, a first end and a second end, wherein the slot is cylindrical and includes a step housing the distal end of the at least one bolt, the slot slidably and non-rotatably retaining the nut, the at least one bolt retaining the at least one clamping block or clamping strip.

A rectangular structure, the rectangular structure comprising at least four corner bracket assemblies, at least one threaded barrel and at least four planar members, each corner bracket assembly including:

• an extruded corner bracket;
• a plurality of nuts;
• a plurality of bolts;
• and a plurality of clamping blocks or clamping strips, the extruded corner bracket including:
• a body and a pair of wings extending the length and defining an outer right angle and a pair of inner right angles, the inner right angles being normal to each other, each inner right angle having a first face and a second face;
• and a slot extending the length, the slot including:
• an elongate opening defined by a proximal edge of each first face, the elongate opening extending the length;
• a first end;
• and a second end, the slot slidably and non-rotatably retaining the nut, housing a distal end of the bolt, and retaining the at least one threaded barrel in one or both of the first end and second end of the slot, the at least four planar members each comprising a first end, a second end, a first side section proximate the first end and a second side section proximate the second end, each first end butted onto one first face, each second end butted onto another first face, a pair of first sides pressed between at least one clamping block or clamping strip and a pair of second faces and a pair of second sides pressed between another at least one clamping block or clamping strip and another pair of second face.
