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 inflatable pool is includes a floor drain having a drainage conduit and two sealing plug. The drainage conduit includes a midsection pipe having an oblong cross section, an inlet cap having a truncated profile, and an outlet cap that transitions from the oblong profile of the midsection to a cylindrical profile.

Abstract: A valve assembly configured for use with an inflatable product, such as a mattress, chair, pool, spa, float, or another suitable inflatable product. The valve assembly includes a first valve component that serves as an opening for inflation and/or deflation of the inflatable product, and a second valve component that serves as an opening for deflation or decompression of the inflatable product.

Abstract: The present disclosure provides a pool ladder with an active protection mechanism. The ladder provides a switch positioned at a significant height from the ground such that children cannot easily reach the switch. When actuated, the switch unlocks a protective door for the ladder and the ladder can be moved to access the steps. As such, the ladder can effectively prevent children from unlocking the protective door and accessing the pool.

Abstract: A mounting rack for supporting a wave-making mechanism in a pool includes a connecting bracket coupled to a side wall of the pool. The connecting bracket includes a support bracket with an adjustable opening configured to receive an upper portion of the pool and at least one connecting bar configured for vertical adjustment along the side wall of the pool. The mounting rack further includes a suspension bracket operably coupled to the connecting bracket and configured to support the wave-making mechanism in the pool, and a bottom surface of the wave-making mechanism is generally parallel to a bottom surface of the pool.

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: An inflatable spa is disclosed having improved strength. A water cavity of the inflatable spa may receive massaging air bubbles and/or jetted water.

Abstract: A welding process of an inflatable product is provided that includes using isolating members between first and second portions of weldable tensioning members to resist the first and second portions of the weldable tensioning structures being welded together during welding of the first portions to a first sheet of weldable material and welding of the second portions to a second sheet of weldable material.
