Abstract: A device for releasable attachment of a flexible cover to a flap or similar, preferably on a truck, trailer or similar.In order to eliminate problems of complexity, expense and functioning associated with earlier designs the device, in addition to a slightly modified flap section (1), consists of only two sections, preferably made of aluminum; a link section (2) and a locking section (3), the former pivoted at its lower end to the flap and the latter pivoted at its lower end to the former, by which arrangement the locking section can fasten the cover (4) against the flap section. Owing to the inherent resilience of the sections the pivot between the link section and the locking section may be snapped over a neutral line to bring about a secure locking of the device.

Abstract: A fastening system for attaching a flexible sheet or cover such as a polyethylene film sheet to a structure comprising a rigid channel which extends along the line where the sheet is to be fastened and attached to the structure, and a plastic lock strip that inserts into the channel and will retain the film relative to the channel. The plastic lock strip includes a spring means that will continuously urge the lock strip into a detent holding position with respect to the channel to insure that this film is held securely even under situations where there is little tension in the sheet or film. The features further include a pinching type detent that increases the holding force for any given tension in the plastic sheet.

Abstract: A space divider panel having fabric sheets positioned to extend across the side surfaces of the panel, with the edges of the fabric sheets being held by channel-like retainers which extend longitudinally along the panel edges. The improved retainer relies upon a spring-type clip for permitting secure holding of the fabric edge, which clip simplifies insertion of the fabric edge into the retainer while effectively providing a secure one-way holding of the edge to prevent its withdrawal. The spring clip solely holds the fabric edge, and accomplishes this without requiring the use of a deformable bead or strip.

Each piece includes a storage channel that runs along the outer edge of the piece and has a narrow inlet on the face of the piece, and a keyway extending along the piece in parallel relation to the channel, the keyway also having a narrow inlet on the face of the piece. In securing the selvage of the fabric sheet to a border piece, the selvage is placed over the face and a zone thereon is trapped within the keyway by means of a compressible spline which overlies the selvage zone and is forced into the keyway through its inlet, the remaining tail of the selvage being stuffed into the storage channel whereby the exposed selvage presents a smooth appearance.

Abstract: A storm window construction includes longitudinally grooved framing strips attached to the four faces of a window casing either inside or outside the window glass. Edge portions of a clear flexible plastic membrane stretched across the window opening and spaced from the glass are held within the grooves of the framing strips by bead strips to maintain the membrane under tension and provide an insulating air space between the membrane and the glass. The bead strips are oblong and can be inserted in the framing strip grooves only along the short diameter of the bead. Once in the groove the bead strip tends to rotate into wedging engagement with cylindrical inner wall portions of the groove under membrane tension to secure the bead and membrane in place. Surface portions of each bead strip intersected by its short diameter and portions of each framing strip at the entrance to the groove may be scored or toothed longitudinally to resist removal of the bead strip from the groove of the framing strip.
