AI Technical Summary

Benefits of technology

The present invention is a hammock stand made from beam material that includes a double horizontal support member operatively fastened to a support leg at each end and a pair of upward arms that can be of a single or double beam. The stand has a low profile, is easy to fold and carry, and includes a quick action tensioning overcenter device. The stand is stable and secure, and can support a person's weight comfortably. The hammock is made with a unique fabric design that includes two bands of fabric diagonally into the bed sheets, which provide stability and comfort. The stand can also be used as a multi-person bench or a compact support for relaxation and nap enjoyment. The stand is low cost, easy to fold and carry, and provides a stable and comfortable support for hammocks.

Problems solved by technology

Any lower angle would not give enough anchor height to prevent the user's back from touching the middle hammock stand bottom structure when lying down in it.
Most hammock stands today, for mere aesthetics, are built of wood, but are quite heavy, up to 90+ lbs., not readily foldable into a compact design and surely not easy to carry for most users; metal ones are lighter, but not as sturdy and they lack the beautiful aspect of wood structures which enhance the beauty of a natural environment.
The cost of fabrication of curved wood structures with around five layers of glued boards of good quality or exotic wood is quite costly and therefore not “amenable” to low cost mass marketing production.
Many other drawbacks of current supports is their excessive height of climbing which causes the hammock to be unstable; most metal stands lack the strength to resist the pull of a higher tension single or double hammock when up to 1,000 lbs. of pull which is carried by each anchor attachment.

first embodiment

[0131]The description of the hammock assembly is related to the need of high tension pull for certain fabrics or rope hammocks in order to provide a stable, nearly horizontal support for the occupant. FIG. 1 through 7 illustrate the present invention with the exception of FIG. 2 which illustrates a support wheel not shown on the other drawings. Therefore any component # for FIG. 1 through 7 included are identical.

[0132]FIG. 1 perspective view illustrates the combination of both the hammock and the stand together; the hammock is represented by a rectangular piece of fabric 30 which is fastened by a straight spreader bar 32 which is linked to the stand by a hook 29 via a chain and ring 28, a series of ropes 36 which are tied to a left and a right eye hook 34; at the other end the fabric is fastened to a curved spreader bar 42 that includes a left and right eye bolt 44 which carry the load to a series of ropes 46 and a ring 47 which receives its pull by a hook and chain assembly 48 tie...

second embodiment

[0137]FIGS. 8 and 9 illustrate the invention similar to the first embodiment with the exception of: a lever 64 replaces the right bolt 18 of FIG. 1 in order to clamp and unclamp the support legs 14 without need for any tool. A carriage bolt 72 goes through a metal plate 66 first, then through a spacer block 68 and the horizontal member 10 with its end thread going through the lever 64 which is threaded through its center as seen on FIG. 9. A wood screw 70 also goes through the plate 66, the spacer 68 and partially into member 10; this screw prevents the plate 66 from swinging away from its alignment with member 10. Similarly a lever 62 is performing the same function at the other end of the horizontal member 10, therefore both support legs 14 and 16 can be rotated in a similar manner as FIG. 6 for the first embodiment. Head bolt 72 should be serrated to prevent its rotation. A hammock 31 illustrates a curved or straight spreader bar 43 which includes a couple of eye bolts 45 holding...

third embodiment

[0141]FIG. 12 illustrates the hammock 30 shown in FIG. 1. This embodiment has a rectangular top material reinforced with a diagonally located pair of wide bands of materials 106 and 108; both materials and fabric are fastened to a spreader bar 102 at one end, the tensioning is provided by a eye bolt 116 and 118 and a series of ropes 112 and 114 tie to a ring 110. At the other end both layers of materials are fastened to a spreader bar 104 which includes a pair of eye bolts 114, a series of ropes 116 are linked to the eye bolts at one end and to a ring 118 at the other end.

[0142]It should be noted that the diagonal bands of fabrics are around 2 percent shorter than the top fabric for the reason that it acts as a flexible lifting at the center of the hammock because of the curve spreader as shown in FIG. 1.

[0143]FIGS. 13A and 13B illustrate how the fabrics of the diagonal bands and top rectangular fabric have a wide hem 175 going around a spreader bar 132. The hammock shows a rectangu...

Abstract

A hammock assembly which provides a lightweight and low cost support for a hammock which requires a medium or a higher tension than currently used. This allows the stand to carry a very low profile with upward arm elevation of only around 30 degrees. In a preferred use the support is easily folded and installed without tools, tensioning of the hammock can be provided by a single action overcenter device; also some pre-tensioning anti-flip ropes can provide extra safety.A hammock bed provides increased lifting at its mid length through a combination of X-shaped fabric formations with transverse strengthening band including dismantling of the straight and curved spreader bars.A second hammock support stand assembly which provides a hammock seat combination that allows indoor use, including a very strong asymmetric support formed as a horizontal X shape.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority from provisional U.S. patent application Ser. No. 61 / 455,203 filed Oct. 16, 2010.BACKGROUND OF THE INVENTION[0002]This invention relates to hammock stand, hammock reinforced structure and compact hammock stand of a new type where the initial hammock tension of 20 to 100 lbs. eliminated the sagging of current hammock which requires up to 36 inches and more free space at the middle of the hammock in relation to the straight line made by the hammock anchors; this 36 inches is made of 12 to 18 inches of natural sagging by the loose tension and weight of the hammock fabric or ropes, the other 18 to 24 inches of height is lost by the weight of the hammock user.[0003]Hammocks and hammock stand assemblies have been used mostly during the last 200 years with most improvements into the foldable and collapsible stands during the last 50 years; because the current hammock requires attachment points at between four and...
