Abstract: A pool liner retainer is disclosed for holding or retaining the top peripheral edge portion or liner bead of a watertight pool liner, such as is used in swimming pool construction. The liner retainer includes an elongate retaining element defining a holding channel for accommodating the liner bead, a longitudinal outward slot communicating with the holding channel, and a longitudinal hinge channel located adjacent to the slot. An elongate closing element depends from the hinge channel to partially close the slot to retain the liner bead therebehind. The closing element is hinged for transverse inward movement to open the slot for insertion of the liner bead, and is biased for transverse outward movement to close the slot. Stop means are provided for preventing outward movement of the closing element into the slot by outward movement of the liner bead located in the holding channel.

Abstract: A swimming pool liner retainer system is shown which includes a holding assembly and a liner bead. The holding assembly is located around the peripheral edge portion of the pool, and the liner bead is formed on the peripheral portion of the swimming pool liner. The holding assembly includes an elongated member defining first and second U-shaped channels. The first channel is adapted to accomodate the liner bead and has a longitudinal extended portion. The second channel is located adjacent to the first channel so that the opening of the second channel faces said extended portion. A sliding insert retractably projects from the second channel and is biased toward said extended portion, so that the insert retracts to allow the liner bead to enter the first channel and then projects toward said extended portion to securely hold the bead in position.
