  • Patent number: 7020915
    Abstract: A hammock has a bed formed from a blank of flexible fabric. The blank is defined by opposed ends and opposed sides, the ends and sides of the blank coinciding with opposed ends and opposed side edges of the hammock respectively. Each side of the blank tapers inwardly from the ends, each end of the blank has a notch having opposed edges of equal length. The opposed edges of each notch taper inwardly from the end towards an apex. The opposed edges of each notch are attached by a seam to form the bed from the blank. Cross-braces proximal the ends of the hammock are connected to the side edges of the hammock at connection points opposed across the bed from one side edge to the opposite side edge. The fabric hangs underneath the cross-braces so that an occupant may rest level on the bed fully under the cross-braces. The hammock is suspended between upright structures, such as trees or posts, using a special connection involving a cargo hook having a hook portion and a ring portion.
