ABSTRACT:
A kit of parts for forming a curved member, and a curved member formed thereby, such curved member being capable of defining curved lines and surfaces and for example serving as a curved ruler, or as a structural member which may be combined with similar curved members to define curved surfaces. The kit of parts comprises a pair of elongated, usually identical strips of extrudable shape and flexible in at least one plane, and a plurality of separate, identical connectors each of the connectors being integrally formed of a single piece of material and each having two spaced apart, identically shaped, joint means both capable of directly engaging with a respective strip at any desired location along the strip. The joint means are such as to hold the strips in spaced, parallel disposition while accommodating various curvatures of the strips, and are such as to hold the strips frictionally against longitudinal movement relative to the connectors and are also such as to hold the connectors substantially perpendicularly to the strips. The connectors are spaced apart at regular intervals between the two strips, and once connected thereto hold the strips to the desired curvature. Both the strips and connectors are preferably formed of plastics.
