Abstract: A safety inlet drain assembly for main and skimmer drains of a swimming pool includes a perforated cylinder in the drain cavity mounted at a lower end on the drain return line and having a domed cap on the upper end to which the drain gate cover is attached by fasteners. The safety drain assembly is configured for precluding complete blockage by pool users in the event of displacement of the cover plate thereby preventing excessive suction conditions otherwise posing physical danger to the users.

Abstract: An inflatable article of furniture (100) includes at least two inflatable mattresses (1, 2), a hinge (5), and at least one tube (3, 4) positioned external to the hinge. The hinge connects the two mattresses together and is adapted to permit rotation of at least one of the inflatable mattresses relative to the other. The tube(s) permits passage of an inflating substance between the first inflatable mattress and the second inflatable mattress such that both mattresses may be rapidly inflated in a single step upon introducing an inflating substance into one of the mattresses. The article of furniture may optionally include a backrest (8) and one or more armrests (9, 10) that are fixedly connected to one of the mattresses and integrally connected together to facilitate use of the article of furniture in several different configurations.
