A portable hammock stand with a plurality of components that can be easily disassembled for transport or storage. The components are preferably made of lightweight metal tubing or other material of similar strength and rigidity. The lateral component on each side consists of an upwardly extending telescoping shaft of adjustable length, detachably fastened at an angle to a horizontal shaft which extends above the ground between two legs or pairs of legs on which the whole structure rests on the ground. The telescoping shaft of the lateral component is connected to the outer ends of the legs by chains which connect to a set of extension springs at the upper end of the telescoping shaft. Each chain is constrained in the middle by an extension spring that is attached to the middle of the telescoping shaft. The lateral components are held in place by chains that stretch between the upwardly extending shafts and the horizontal shaft. The tension in the springs maintains the structure of the hammock stand which can thus be lifted and moved as a whole. The hammock is connected to the upper ends of the telescoping shafts and when occupied, the weight of the occupant further stretches the springs resulting in an inward tilting of the upwardly extending shafts with a vertical springing movement of the hammock. The stretching of the springs also allows a side to side swaying of the shafts which prolongs the swinging of the hammock. The combination of movements provides a uniquely relaxing experience for an occupant of the hammock. |
