Abstract: An inflatable spa having improved strength includes a water cavity that receives massaging air bubbles and/or jetted water.

Abstract: A multi-chamber inflatable mattress includes a main air chamber, upper and lower peripheral air chambers, and an upper air chamber. The main air chamber includes internal tensioning structures which cooperate with a bottom mattress panel and a lower intermediate panel to provide a generally box-shaped, mattress-sized inflatable structure upon pressurization. A second, upper intermediate panel cooperates with a top mattress panel to define an upper air chamber which defines the sleeping surface. The main air chamber receives pressurized fluid directly from a valve, while the lower and upper peripheral air chambers are in direct fluid communication with the main air chamber but not the valve. The upper air chamber is in direct fluid communication with the upper peripheral air chamber, but not the main chamber or valve.

Abstract: An internal tensioning structure for use in an inflatable product fulfills the basic function of maintaining two adjacent inflatable surfaces in a desired geometric arrangement when the inflatable product is pressurized. The tensioning structure is formed by connecting a pair of plastic strips sheets via spaced-apart strands, such as strings or wires. When pulled taut, the strands provide a high tensile strength between the two opposed plastic strips. At the same time, the plastic strips facilitate a strong, long-lasting weld between the tensioning structure and the inflatable product.

Abstract: A combination ladder assembly and pool includes a pool having a side wall and a support member positionable along an inner surface of the side wall of the pool. The support member may include at least one aperture. Additionally, the combination ladder assembly and pool further includes a ladder positionable along an outer surface of the side wall of the pool. The ladder may be removably coupled to the support member. The ladder further includes at least one leg having a first end and a second end and a plurality of steps. The plurality of steps may be coupled to the leg of the ladder between the first end and the second end of the leg. The ladder may be moveable between a use position, permitting ingress into the pool, and a storage position. When the ladder is in the use position, the leg of the ladder is supported by the support member. When the ladder is in the storage position, the ladder extends from the aperture of the support member to cantilever from the support member.

Abstract: A swing set (10) is shown including a support beam (16), a plurality of legs (14), and swing apparatus (18, 24, 26) supported by the support beam. The support beam and legs include a plurality of tubes (28, 30, 38, 40, 44) coupled together by connectors (42, 48). The connectors include an inner tube (66) and a cover (68, 68?) positioned over the inner tube. Feet (46) are provided at the lower ends of the legs that rotate relative to the legs.

Abstract: A two-in-one copper chloride/copper bromide disinfector and a method of controlling the same. In operation, when copper is released, the positive and negative electrodes of a copper billet are periodically reversed, while the positive and negative electrodes of a titanium plate/graphite polar plate are in an uncharged state. When chlorine/bromine is released, the positive and negative electrodes of a titanium plate/graphite polar plate are periodically reversed, while the positive and negative electrodes of the copper billet are short-connected, then connected to the negative electrode of the titanium plate/graphite polar plate, or applied thereon with an electric voltage that is lower than the electric voltage of the negative electrode of the titanium plate/graphite polar plate. With this method, the copper billet out of operation is shorted-connected to the negative electrode of the titanium plate/graphite polar plate or connected to an electric voltage that is lower than that of the negative electrode.

Abstract: The present disclosure provides a swimming pool ladder with a barrier. The ladder includes two ladder sections. A top platform for supporting is connected between the upper portions of the two ladder sections and disposed above the swimming pool. The two ladder sections are respectively positioned inside and outside the swimming pool. The ladder section includes two parallel-disposed rails and a plurality of steps. The plurality of steps are mounted at intervals along the two rails from top to bottom. A barrier is provided that is perpendicular to the inner side face of the first ladder section. The barrier has a triangle shape, one edge of which is adjacent the inner side face of the first ladder section and fixed on at least two steps through at least two connectors and another edge is adjacent the inner sidewall of the swimming pool. The top end of the barrier is spaced from the top platform by a distance and the bottom end is adjacent the floor of the swimming pool.

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.
