Abstract: The present invention provides a retainer frame of an outdoor above ground pool, which includes a plurality of posts and a plurality of sets of beams, connected between pairs of adjacent posts to form a polygonal shaped retainer frame. Each beam has two end portions, and each post has one or more receiving ports for receiving the end portions of a set of beams. The retainer frame also includes a plurality of locking members for locking the end portions of the set of beams in the receiving ports of the corresponding post. The beams are capable of swinging around a longitudinal axis of the posts within a range of swinging motion so that the same components (posts, beams and locking members) can be used to form polygonal shaped retainer frames having different numbers of sides.

Abstract: A chlorine generator includes a main water channel for connecting to a pool and a subsidiary water channel connected between two points on the main water channel. A feed valve, a brine tank, a pump and an electrolytic tank are located on the subsidiary water channel. Salt is added into the brine tank and dissolved in water drawn in from the main water channel, and the high concentration saline solution is pumped from the brine tank into the electrolytic tank where chlorine is generated from the saline. The chlorinated solution from the electrolytic tank is then mixed with the water in the main water channel. A stirring device is provided at the bottom of the brine tank to stir the water therein to facilitate the generation of high concentration saline solution. Salt is electrolyzed without being dissolved into the swimming pool directly, thereby reducing harmful effects to swimmers.

Abstract: A swimming pool ladder typically utilized with a large capacity swimming pool for enabling bathers to conveniently enter and exit the pool. In its most fundamental embodiment, the swimming pool ladder includes a first ladder section connected to a second ladder section by a top platform. Each ladder section includes a pair of J-shaped side rails for providing a ladder frame. A plurality of rung anchors are mounted upon each of the side rails for supporting a plurality of rungs. Each of the rung anchors includes a load bearing flange. Further, each of the rungs includes a pair of U-shaped openings and a pair of grooves formed within the U-shaped openings for receiving and cooperating with one of the rung anchors and the corresponding load bearing flange. Finally, a plurality of retainer pins are provided for removably securing the rungs to the rung anchors.
