Abstract:
A flexible channel has inturned overhanging side edges overhanging the base either by the same or different amounts. A flexible tape has beads formed along each edge and these beads engage under the side edges of the channel when installed. Plastic film or the like is laid over the channel whereupon the tape or locking strip is engaged over the film and forced into engagement within the channel. If the channel with different dimensions is used, the tape or locking strip is first engaged under the widest edge and then snapped into engagement under the narrowest edge. When tension is placed on the film in a direction away from the widest edge, the tape is pulled into further engagement under the narrow edge which prevents the tape or locking strip from disengaging from the channel. When the pull on the tape is from either or both directions, the channel with equal dimensioned edges is used and a tool is then required to buckle the tape or locking strip prior to its being engaged under the side edges of the channel. In both instances the tape or locking strip takes up a concave configuration relative to the base of the channel due to the fact that the beads on the edges of the tape are on the underside and engage the base of the channel with the plastic film sandwiched therebetween.
