Abstract: Several embodiments of the shutters employ a variety of synergistic features which may be used individually or in combination to produce a shutter capable of more completely shutting out light. One aspect is the use of a two-step overlapping end to provide a complementary fit in order to shut out light. Another aspect is the use of an angled engagement pin which engages the louver not at its edge, but into its main expanse and nearer the center of pivot of each louver. Another aspect is the use of an accommodation space to accommodate the “U” shaped attachment member of the simultaneous actuation handle, which accommodation space can vary in size and depth to accommodate structures extending from the simultaneous actuation handle. Regardless of relative size, the louvers, engagement pins, and simultaneous actuation handle can be disciplined to form a neater appearance on the shutter assembly.

Abstract: A portable activity floor comprised of a plurality of separate panels that can be readily and selectively interlocked together into a finalized configuration. Each panel has an underlayment providing a core with spaced stringers fastened to the underside thereof. Elongated finishing strips mounted on the upper surface of the underlayment form the outer surface of the panel. In one type of floor assembly, alternate strips are longer than their adjacent strips at the inner side of each panel to form laterally spaced interlock fingers. A pair of hinge members pivotally connects adjacent panels to one another and allows them to be relatively pivoted on a fixed axis with finger interlock alignment accuracy from an initial connected position to a fully assembled position in which the fingers of the finishing strips closely mesh and interlock. Further, the hinge members when connected prevent lateral movement of adjacent panels.
