Abstract: A retainer for a pool liner has an elongate retaining element includes a longitudinal holding channel for accommodating a liner bead, the channel having an upper wall with a downwardly extending second flange, a rear wall and a bottom wall with a forwardly positioned upwardly extending first flange. The area between the second flange and the first flange forms a slot for insertion of the bead into the channel. A third flange is positioned outside of said channel on the upper wall. An elongate resilient cap has a first hooked peripheral edge portion for hooking over the second flange, and an opposed second hooked peripheral edge portion for hooking over the third flange. The cap can be retained by snapping the hooked portions over the respective second and third flanges. The first peripheral edge portion has an outwardly disposed shoulder extending toward the first flange.

Abstract: A multi-gasket sealing assembly or mount is disclosed for improved mounting of a swimming pool water skimmer in an opening in a pool wall of the type having a metal wall portion and a flexible inner sheet liner. The water skimmer has a housing defining a water inlet chamber for intake of water and an annular chamber end portion which protrudes through the pool wall opening. The housing also has an outwardly projecting peripheral flange spaced from the chamber end portion, the flange being bolted to the metal wall portion. A continuous gasket is located around the chamber end portion. An annular face plate is connected to the chamber end portion to compress the gasket and also to press the pool liner against the metal wall portion to prevent water from getting behind the liner. Another gasket is compressed between the peripheral flange and the metal wall portion to seal against the ingress of sand and other particulate matter into the skimmer from behind the pool wall.

Abstract: A method of assembling a fence is disclosed and a joint for attaching pickets to a horizontal rail in the fence. The horizontal rail has apertures formed therein through which the pickets slide. The apertures have projecting tongues which engage recesses formed in the pickets to form a joint to suspend the pickets in the rail. Rotation of the horizontal rail locks the pickets in place.
