Abstract
Abstract A frame includes four corner pieces and four side members. Each corner piece is formed with two tubular formations which are at right angles to each other and which have longitudinally extending slots in their respective walls. The side members have formations and which are complementary in shape to the tubular formations and which are frictionally engageable therewith. The opposed ends of each side member are engaged with two corner pieces respectively whereby a square or rectangular frame is constructed for a planar member with peripheral portions of the planar member being located in longitudinally extending openings in the side members respectively.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
165 words
A frame for at least one planar member, said frame comprising: four corner pieces and four side members to be assembled into a rectangular configuration; each said corner piece including two side portions which are disposed at right angles to each other, each said side portion including a tapered longitudinally extending formation, and a bridging piece which extends between said two side portions; each said side member including a longitudinally extending slot, and a longitudinally extending formation which is engageable with the said tapered longitudinally extending formation of a respective said corner piece thereby frictionally to secure opposite ends of said side member to respective said corner pieces; said side members adapted to be paired with said longitudinally extending slots of each pair of side members opposing one another for receiving peripheral portions of the planar member; and each said bridging piece having adjustment means for bearing on an underside of the planar member thereby to bias the planar member away from said bridging pieces.
Claim 2
Dependent Claim
165 words
A frame for at least one planar member, said frame comprising: four corner pieces and four side members to be assembled into a rectangular configuration; each said corner piece including two side portions which are disposed at right angles to each other, each said side portion including a tapered longitudinally extending formation, and a bridging piece which extends between said two side portions; each said side member including a longitudinally extending slot, and a longitudinally extending formation which is engageable with the said tapered longitudinally extending formation of a respective said corner piece thereby frictionally to secure opposite ends of said side member to respective said corner pieces; said side members adapted to be paired with said longitudinally extending slots of each pair of side members opposing one another for receiving peripheral portions of the planar member; and each said bridging piece having adjustment means for bearing on an underside of the planar member thereby to bias the planar member away from said bridging pieces.
Claim 3
Dependent Claim
74 words
A frame according to claim 1, wherein each said side portion of each said corner piece includes a socket-like cover member which receives and obscures at least an end portion of a respective said side member, each said cover member having a longitudinally extending opening which overlies a section of said longitudinally extending slot of the respective said side member so that a peripheral portion of the planar member can pass into said slot.
Claim 4
Dependent Claim
83 words
A frame according to claim 1, further comprising at least two hangers engaged respectively with two opposed said side members which, in use, extend substantially vertically, each said hangar being slidably engaged with its respective side member and including a fixing formation for a cord to extend between said hangars, said fixing formations being so positioned that when the frame is suspended from the cord, each said hangar tends to rotate relatively to its respective side member and thereby is frictionally locked thereto.
