Abstract
Abstract A screen construction applicable to exhibition and display purposes but also applicable to booths for attendants or projection equipment, room dividers or toy building kits comprises a plurality of support members of elongate form and uniform circular cross-section, a plurality of rectangular panels, and a plurality of clips secured at least two on each of two opposite edges of each panel and snapping on to the support members, thus enabling adjacent columns of panels to be set at any inclination to each other, the clips on one edge of any panel preferably having spacings from one end of that edge differing from their spacings from the other end of that same edge by at least the thickness of the clips measured in the direction of that edge, whereby two adjacent panels can be attached to one support member with the corresponding edges of the panels perpendicular to the support member in register with each other thus enabling a solid screen to be constructed.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
97 words
A screen construction comprising a plurality of support members of elongate form and uniform circular cross-section in contact with the floor, a plurality of rectangular panels, and a plurality of clips secured at least two on each of two opposite edges of each panel, said clips snapping around the support members, each of said clips being open-ended and extending around greater than 180° of the circumference of said circular cross-section support member, adjacent ones of said panels thereby being orientatable at any angle relative to each other, and said support members being free-standing without any overhead support.
