Abstract: A baffle tile has a tile and a baffle. The tile is sized and shaped to be placed in a drop ceiling grid, and has a slot through its thickness. The body of the baffle is inserted into the slot in the tile so that the baffle hangs down from the tile. A pair of folding flaps are defined in an upper extent of the baffle by respective fold lines. The folding flaps are folded outwardly and down, such that they abut the upper surface of the tile. Folded down, the folding flaps define a locking slot. A locking member with features complementary to the locking slot is inserted into the locking slot to lock the folding flaps into position. The baffle itself may have additional fold lines so that it can be folded into its usable configuration from a flat sheet of material, without adhesives or fasteners.

Abstract: A baffle tile that folds from a flat configuration into a three-dimensional configuration is disclosed. In the three-dimensional configuration, it includes a rim portion and a baffle portion. The rim portion is split into halves. Each half of the rim portion terminates in a pair of upwardly-folded, spaced-apart tabs. When the baffle tile is in its three-dimensional configuration, each tab meets and abuts its counterpart from the other half of the rim portion. Each tab has a notch in it, arranged such that the notches of abutted tabs are aligned. A retaining structure inserts into each set of aligned notches. The retaining structures prevent the tabs of the baffle tile from separating. In some cases, a single retaining structure that has approximately the same size as the baffle tile itself may also serve as a cap to enclose the tile.
