Abstract: A multi-functional hammock assembly for providing user comfort and enjoyment may include first and second elongated rectilinear poles, a hammock, and first and second sleeves slidably positioned about the bottom ends of the first and second poles. The hammock assembly may further include at least one accessory and a mechanism for effectively anchoring the at least one accessory to the first and second poles. The assembly may further include a mechanism for synchronously rotating at least one of the first and second sleeves and the first and second poles about a centrally registered longitudinal axis passing through the one pole to thereby conveniently assist a user to penetrate the one sleeve into a ground surface.

Abstract: A fluid flow nozzle is formed by a plurality of adjacent L-shaped channels forming successive channel pairs. Each channel has a linking member joined to a radial member. Each linking member is welded to an adjacent linking member forming a contiguous surface of linking members. Each radial member is oriented approximately perpendicular to a first side of the contiguous surface. A circumferentially enclosed chamber is formed on a second side of the contiguous surface. Each radial member is laser welded to a jacket at a distal end of each radial member. The jacket is oriented approximately parallel with the contiguous surface and separably spaced from the contiguous surface by the radial members. Each radial member forms one of a plurality of flow chambers between its adjacent radial member, the jacket and the contiguous surface. The flow chambers advantageously contain fluid in the event of a radial member rupture.
