Abstract
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.
Claims7
A hammock comprising:
- a bed of fabric having first and second ends, and sides;
- one or more elongated tension members connecting the first end to a first vertical support member and one or more elongated tension members connecting the second end to a second vertical support member;
- an intermediate support supporting the bed of fabric at a knee position between the first and second ends, and being suspended between the first and second support members, the intermediate support providing elevated knee support to a user so as to protect the knee from backward bending force on the knee due to downward curvature of the hammock, the intermediate support being connected between the first end and the intermediate support on at least one end of the hammock by at least cables running through sleeves in each edge of the bed of fabric, the intermediate support being connected to the second support by flexible elongated tension members interconnecting the intermediate support with the second support.
A hammock comprising:
- an elongated bed formed of flexible material having head and foot ends and sides;
- substantially rigid head and foot end spreader bars attached respectively to the head and foot ends of the bed;
- an intermediate bed support positioned under the bed at an intermediate position between the head and foot end spreader bars, the intermediate position being such that the intermediate bed support is positioned generally under the knees of a person using the hammock;
- flexible, elongated head and foot spreader bar tension members attached respectively to the head and foot spreader bars, head tension members having outer ends that are attached to a head end vertical support at a first elevation, foot tension members having outer ends that are attached to a foot end vertical support at a second elevation, the intermediate bed support being suspended between the vertical supports by tension members at a third elevation, the first, second and third elevations being such that the third elevation is higher than the second elevation, such that the intermediate bed support maintains the knees of a hammock occupant at an elevated position that resists a reverse flexing of the occupant's knees when the occupant is resting on the hammock with his knees positioned over the intermediate bed support.
