TECHNICAL FIELD AND BACKGROUND OF THE DISCLOSURE

The present disclosure relates broadly and generally to a convertible hammock assembly, and method for converting a flexible hammock to an inclined form.

SUMMARY OF EXEMPLARY EMBODIMENTS

Various exemplary embodiments of the present disclosure are described below. Use of the term “exemplary” means illustrative or by way of example only, and any reference herein to “the invention” is not intended to restrict or limit the invention to exact features or steps of any one or more of the exemplary embodiments disclosed in the present specification. References to “exemplary embodiment,” “one embodiment,” “an embodiment,” “various embodiments,” and the like, may indicate that the embodiment(s) of the invention so described may include a particular feature, structure, or characteristic, but not every embodiment necessarily includes the particular feature, structure, or characteristic. Further, repeated use of the phrase “in one embodiment,” or “in an exemplary embodiment,” do not necessarily refer to the same embodiment, although they may.

It is also noted that terms like “preferably”, “commonly”, and “typically” are not utilized herein to limit the scope of the claimed invention or to imply that certain features are critical, essential, or even important to the structure or function of the claimed invention. Rather, these terms are merely intended to highlight alternative or additional features that may or may not be utilized in a particular embodiment of the present invention.

According to one exemplary embodiment, the present disclosure comprises a convertible hammock assembly. The hammock assembly incorporates a flexible hammock comprising a fabric bed (or hammock body) having opposing ends and opposing sides, and suspension lines extending from the opposing ends of the fabric bed for hanging the flexible hammock between spaced apart structures. An elongated rigid spreader bar is located at one end of the fabric bed. Means are provided for selectively laterally tensioning the fabric bed between opposite ends of the spreader bar, such that the flexible hammock is convertible between a generally inclined condition with increased lateral bed tension at the spreader bar, and a generally flat condition with reduced lateral bed tension at the spreader bar.

According to another exemplary embodiment, the fabric bed comprises a fabric end panel having a top edge adjacent to the spreader bar and a bottom edge having a length greater than the length of the top edge.

According to another exemplary embodiment, the means for selectively laterally tensioning the fabric bed comprises a flexible conversion cord secured to the fabric end panel. The conversion cord has first and second free ends extending through respective caps located at opposite ends of the spreader bar. Pulling the free ends of the conversion cord outwardly from the fabric bed draws the bottom edge of the fabric end panel upward towards the top edge of the fabric end panel, thereby increasing the lateral bed tension at the spreader bar.

According to another exemplary embodiment, the conversion cord is slidably received through a hem formed at the bottom edge of the fabric end panel. The hem may be formed entirely along the bottom edge of the fabric end panel or only partially along the bottom edge of the fabric end panel.

According to another exemplary embodiment, fasteners are located at respective free ends of the conversion cord, and are adapted for being releasably attached to the hammock suspension lines.

According to another exemplary embodiment, the fasteners of the conversion cord comprise toggles. Alternatively, the fasteners may comprise karabiners or the like.

According to another exemplary embodiment, the hammock suspension lines comprise respective loops adapted for receiving the toggles of the conversion cord.

According to another exemplary embodiment, first and second release handles are attached to the conversion cord (or fabric bed) and spaced apart from respective toggles. The release handles allow the conversion cord to be manually pulled inwardly towards the fabric bed, thereby reducing the lateral bed tension at the spreader bar such that the flexible hammock converts back to its generally flat condition. Alternatively, the conversion cord could be slidably moved without the use of release handles.

According to another exemplary embodiment, a first (cord) guide is fixed to the hammock suspension line adjacent the spreader bar, and defines a guide opening slidably receiving the conversion cord.

According to another exemplary embodiment, a second (line) guide is affixed to the conversion cord adjacent the toggle, and defines a guide opening slidably receiving the hammock suspension line.

According to another exemplary embodiment, the fabric bed is constructed in whole or in part of a ripstop fabric.

According to another exemplary embodiment, a second elongated rigid spreader bar is located at the opposite end of the fabric bed. The opposite end of the fabric bed may also include means for selectively laterally tensioning the fabric bed, as described herein.

In another exemplary embodiment, a convertible hammock assembly of the present disclosure comprises a flexible hammock, an elongated rigid spreader bar, and a flexible conversion cord. The flexible hammock comprises a fabric bed having opposing ends and opposing sides, and suspension lines extending from the opposing ends of the fabric bed for hanging the flexible hammock between spaced apart structures. The spreader bar is located at one end of the fabric bed. The conversion cord is secured to the fabric bed, and has first and second free ends extending through respective caps located at opposite ends of the spreader bar, whereby pulling the free ends of the conversion cord outwardly from the fabric bed converts the flexible hammock from a generally flat condition with reduced lateral bed tension at the spreader bar to a generally inclined condition with increased lateral bed tension at the spreader bar.

The term “hammock” refers broadly herein to any hanging bed, seat, couch, or other suspended or partially suspended support or sling made of any rigid and/or flexible material including nylon, canvas, netted cord or rope, rigid framing or the like. Exemplary hammocks may have straps, cords, cables, lines, ropes, or other extensions attached to supports at one or both ends. The hammock bed or body may be any size, shape or pattern. As used herein, the terms “cord”, “line”, and “strap” refer broadly to any flexible elongated structure including rope, cable, webbing, and the like.

Referring now specifically to the drawings, a convertible hammock assembly according to one exemplary embodiment of the present disclosure is illustrated in FIGS. 1 and 2, and shown generally at broad reference numeral 10. The exemplary assembly 10 comprises a flexible fabric hammock 11 having opposing head and foot ends 12, 13, opposing longitudinal sides 14, 15, and a pair of elongated rigid spreader bars 16, 18. The ends 12, 13 and sides 14, 15 of the hammock 11 define a fabric bed 20 for supporting one or more users. The spreader bars 16, 18 are located at the head and foot ends 12, 13 of the hammock 11, and function to laterally open or spread-apart the longitudinal sides 14, 15 of the fabric bed 20. In one exemplary embodiment, fabric end panels 22, 24 are secured to respective spreader bars 16, 18 (either directly or indirectly), and attached to the fabric bed 20 of the hammock 11 at its head and foot ends 12, 13. Each end panel 22, 24 has a top edge 25 residing directly adjacent the spreader bar 16, 18, and a normally-relaxed (loosely tensioned) bottom edge 26 sewn directly to the fabric bed 20 at a reinforced seam—the length of the bottom edge 26 being longer than a length of the top edge 25. The hammock bed 20 and end panels 22, 24 may be constructed (in whole or in part) of any suitable fabric, such as any fiber-based material. For example, the hammock 11 may comprise a lightweight durable and breathable, quick drying, 70-denier, nylon ripstop fabric. The exemplary hammock bed 20 may be single or double nest, and may have a load capacity of 400 pounds or more. The exemplary end panels 22, 24 may be constructed of a more open-mesh nylon fabric or “netting”. The exemplary spreader bars 16, 18 may be constructed of a lightweight aluminum or other metal, plastic, fiberglass, wood, composite material, or the like.

Flexible suspension lines 28, 29 are attached to looped webbing 31 sewn to the fabric bed 20 at respective head and foot ends 12, 13 of the hammock 11. The suspension lines 28, 29 extend outwardly from the hammock 11 through ringed “O-shaped” (or open “C-shaped”) end caps 32 of the spreader bars 16, 18. Each line 28, 29 comprises a centrally-located metal karabiner 34 or other such fastener. The metal karabiners 34 serve to releasably secure the assembly 10 to cooperating hammock straps, flexible cables, eye bolts or other hardware (not shown). In one embodiment, a pair of multi-looped hammock straps are used to hang the assembly 10 from elevated suspension points between spaced apart structures, such as trees, vertical frames, posts, or the like—or any combination thereof. One exemplary hammock strap having a multi-looped construction is disclosed in Applicant's prior issued U.S. Pat. Nos. 9,003,579; 9,320,343; and 9,622,566. The complete disclosures of these prior patents are incorporated herein by reference. In one embodiment, the suspension lines 28, 29 are constructed of UHMWPE rope, such as that sold under the brand name Dyneema®.

As discussed further below, the exemplary hammock assembly 10 is designed to readily convert between a generally flat-lying bed form, as shown in FIGS. 1 and 11, and a generally inclined bed form shown in FIGS. 2 and 12. In the inclined form, lateral tension in the fabric bed 20 is increased between opposite ends of the spreader bar 16 at the head end 12 of the hammock 11. In the embodiment of FIGS. 1 and 2, a manual conversion cord 40 and release handles 41, 42 are used to selectively adjust the fabric tension at the head end 12 of the hammock bed 20. Diagrammatic FIGS. 3-8 demonstrate operation of the conversion cord 40 and release handles 41, 42 in the exemplary hammock assembly 10. Alternative exemplary means for converting the hammock assembly 10 are illustrated in FIGS. 13-18, and discuss further below.

Referring to FIGS. 3-8, 9, 9A, 10, and 10A, in one embodiment the conversion cord 40 comprises a single flexible line extending through an open hem 44 formed along the bottom edge 26 (or seam) of the end panel 22 at the head end 12 of hammock bed 20. Alternatively, in an embodiment of the hammock assembly 10 without one or both end panels 22, 24, the conversion cord 40 may be secured directly or indirectly to the fabric bed 20 at or proximate an edge seam. The release handles 41, 42 are sewn directly to the conversion cord 40 and bottom hem 44 of end panel 22 at spaced-apart points along the fabric seam where the conversion cord 40 extends from the bottom hem 44 upwardly towards the ringed end caps 32 of spreader bar 16. Free ends of the conversion cord 40 pass through the ringed end caps 32 of spreader bar 16, through pairs of cord and line guides 46, 48, and terminate at rigid toggles 49. The cord guide 46 is affixed to the suspension line 28 adjacent the end cap 32 of spreader bar 16, and defines a guide opening 46A which slidably receives the conversion cord 40. The line guide 48 is affixed to the conversion cord 40 adjacent the toggle 49, and defines a guide opening 48A which slidably receives the suspension line 28. The suspension line 28 at the head end 12 of the hammock 11 has strategically spaced, integrally-formed loops 51 designed to receive respective toggles 49 of the conversion cord 40.

FIGS. 9 and 9A show the hammock assembly 10 in its generally flat-lying form with the toggles 49 located adjacent respective end caps 32 of the spreader bar 16. FIGS. 10 and 10A show the hammock assembly 10 converted to its generally inclined form with the toggles 49 inserted into respective loops 51 of the suspension line 28. The process for converting exemplary hammock assembly 10 is described further below.

FIG. 3 represents components of the hammock assembly 10 shown in the generally flat-lying bed form. To convert the hammock assembly 10 to its inclined form, the user grasps and pulls each toggle 49 of the conversion cord 40 outwardly from the hammock 11 towards each loop 51 of the suspension line 28, as indicated by direction arrows 52 in FIG. 4. The toggles 49 may be pulled one at a time, or simultaneously with the help of a second user. As the toggles 49 are pulled, the conversion cord 40 begins to lift and tension the bottom edge 26 of the end panel 22, thereby increasing fabric tension at the head end spreader bar 16 of hammock 11. The increased fabric tension is sufficient to support the upper torso of the user in a generally inclined “alert” position shown in FIG. 11. In this position, the user can enjoy a more complete view of his or her surroundings outside of the hammock assembly 10. When the bed conversion is completed, the toggles 49 are inserted into the loops 51 of the suspension line 28 (as demonstrated in FIG. 5) to retain the hammock assembly 10 in its generally inclined form.

When the user desires to return the hammock assembly 10 to its generally flay-lying form, the toggles 49 are first removed from the loops 51 of the suspension line 28 as demonstrated in FIG. 6. Each release handle 41, 42 is then grasped and pulled downwardly, as indicated by arrows 58 in FIG. 7, thereby releasing the fabric tension at the head end spreader bar 16 of hammock 11. This returns the end panel 22 to its loosely tensioned condition, such that a user lying in the hammock 11 is supported as shown in FIG. 12 in a relatively flat “privacy” position substantially enveloped by the sides 14, 15 of the fabric bed 20.

A further embodiment of the exemplary hammock assembly 60 is disclosed in FIGS. 13 and 14. Like elements described above with reference to the hammock assembly 10 are indicated below and in the drawings in prime notation (′). In this alternative embodiment, the means for selectively laterally tensioning the fabric bed 20′ at the head end spreader bar 16′ includes a plurality of cooperating toggles 61 and loops 62 spaced apart in pairs along the bottom edge 26′ of the end panel 22′. With the toggles 61 detached from their corresponding loops 62, as shown in FIG. 13, the hammock assembly 60 is loosely tensioned at the head end 12′ of the fabric bed 20′, such that the hammock 11′ resides in a normal generally flat-lying form. By attaching the toggles 61 and loops 62 around the head end spreader bar 16′, as shown in FIG. 14, the bed tension at the spreader bar 16′ increases thereby converting the hammock assembly 60 from its generally flat-lying form to a generally inclined form.

A third embodiment of the exemplary hammock assembly 70 is disclosed in FIGS. 15 and 16. Like elements described above with reference to the hammock assembly 10 are indicated below and in the drawings in double prime notation (″). In this alternative embodiment, the means for selectively laterally tensioning the fabric bed 20″ at the head end spreader bar 16″ includes an open-ended hem 71 formed along the bottom edge 26″ of the end panel 22″. When the spreader bar 16″ is removed from the bottom hem 71, as shown in FIG. 15, the hammock assembly 70 is loosely tensioned at the head end 12″ of the fabric bed 20″, such that the hammock 11″ resides in a normal generally flat-lying form. By reconfiguring the hammock assembly 70 to insert the spreader bar 16″ through the bottom hem 71, as shown in FIG. 16, the bed tension at the spreader bar 16″ increases thereby converting the hammock assembly 70 from its generally flat-lying form to a generally inclined form.

A fourth embodiment of the exemplary hammock assembly 80 is disclosed in FIGS. 17 and 18. Like elements described above with reference to the hammock assembly 10 are indicated below and in the drawings in triple prime notation (u). In this alternative embodiment, the means for selectively laterally tensioning the fabric bed 20′″ at the head end of hammock 11″ includes a length-adjustable (e.g., telescoping) spreader bar 81. When the spreader bar 81 is in a retracted condition, as shown in FIG. 17, the hammock assembly 80 is loosely tensioned at the head end 12′″ of the fabric bed 20′″, such that the hammock 11′ resides in a normal generally flat-lying form. By extending the spreader bar 81, as shown in FIG. 16, the bed tension at the spreader bar 81 increases thereby converting the hammock assembly 80 from its generally flat-lying form to a generally inclined form. The exemplary spreader bar 81 may comprise multiple telescoping sections with one or more spring-loaded detents and longitudinally-spaced holes enabling ready and convenient length adjustment.
