发明名称 Hammock with intermediate support
摘要 A hammock is supported by vertical supports connected to hammock spreader bars at the head end and the foot end of the hammock at two vertically displaced points. An intermediate support comprising a transverse flexible strap suspended between the vertical support members at a user's knee region of the hammock raises the hammock in the knee region so as to remove the concavity at the location and reduce backward knee joint stress on the person reclining in the hammock.
