Abstract: A pool and spa plumbing adapter to relocate existing directional water flow plumbing fittings to new positions to accommodate new surfacing overlaid on the existing pool or spa surface. The adapter provides for a threaded engagement with existing plumbing and has a shoulder portion providing a visual cue for proper rotational translation of the adapter into the existing plumbing fitting to accommodate the new surface layer. A sealing ring can be provided extending above the shoulder portion to prevent fluid passage between the new surface and the adapter and to prevent rotation of the adapter.

Abstract: A drain cover adapted for engagement in a cavity above the drain aperture in the surface forming a pool or spa and below a top component. The top component features a substantially transparent center section which provides a view of a display component housed in a display cavity formed between the drain aperture and the center section of the top component. The display component is easily changed by removal of the top component, replacing the display component, and remounting the top component.

Abstract: A fluid vortex inducing component adapted for placement between an anti-vortex drain cover of a pool or spa and the underlying drain. The device employs radially oriented blades to induce a cyclonic or vortex flow to the plurality of individual linear fluid streams traversing passages in the sidewall of the drain cover to enhance fluid flow in the underlying drain. It may be installed as a new part to existing or new drains or in a method for retrofitting existing drains a component to induce the vortex to drained water can be installed.

Abstract: A novel furniture leg attachment system is provided for attaching legs to articles of furniture, for example chairs. In one embodiment, a furniture member, such as a seat, is provided which defines a slot and a fastener first bore intersecting the slot. The leg member has a tab received within the slot. The tab defines a fastener second bore which is aligned with the fastener first bore when the tab is correctly received within the slot. A fastener is inserted through the fastener first bore and the fastener second bore to retain the tab within the slot. In alternate embodiments, the leg member may have two, three or more tabs, sized and shaped to fit within corresponding slots in the furniture member. In one embodiment, a smooth fastener such as a peg is used to retain the tabs within the slots, allowing easy assembly. Locking means device may be included to retain the fastener in place and to make disassembly difficult.
