Referring now specifically to the drawings, a portable and collapsible hammock stand 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 present hammock stand 10 is designed for hanging any flexible hammock 11, such as a conventional single or double-nest outdoor hammock. Such hammocks are commonly fabricated of a lightweight durable and breathable quick drying fabric, such as nylon, and may have a load capacity of 400 pounds or more. Typically, short attachment cords located at opposite ends of the hammock 11 are tied to respective metal karabiners 12 (snap hooks, S-hooks, O-rings, D-rings, and/or other hardware). The karabiners 12 may be used to releasably attach the hammock ends to the present hammock stand 10, as described further below. In exemplary embodiments, the hammock stand 10 is constructed of lightweight shock-corded components, and is designed for convenient transport and assembly at any desired location.

Referring to FIGS. 2, 3 and 4, the present hammock stand 10 includes first and second identical free-standing pod assemblies 20, 20′ separated by an elongated horizontal ridge pole 21. The ridge pole 21 may be formed in multiple hollow sections having respective male and female connecting ends. While the description below refers primarily to elements and features of pod assembly 20, it is understand that pod assembly 20′ incorporates identical elements and features.

Each pod assembly 20, 20′ incorporates a plurality of elongated, equally-spaced, rigid legs 22A, 22B, 22C, and 22D. A top fastening hub 25 holds the legs 22A-22D together proximate their top ends, while the bottom ends of the legs 22A-22D diverge to the ground. As best shown in FIG. 3, the exemplary fastening hub 25 comprises a removable cap 26, integrally molded ribs 27, and four equally spaced underside leg sockets 28A, 28B, 28C, and 28D. The leg sockets 28A-28D are configured to removably receive respective top ends of the legs 22A-22D. Each leg 22A-22D may be formed in multiple hollow tubular sections having connecting male and female ends assembled together by an elastic shock cord. As shown in FIGS. 3 and 4, a first shock cord 31 attaches at bottom ends of legs 22A and 22B, and extends through the assembled legs 22A, 22B, through adjacent leg sockets 28A, 28B and through top openings 32A, 32B in the fastening hub 25. The second pair of legs 22C and 22D is assembled in an identical manner using a second elastic shock cord 34 attached at bottom ends of the legs 22C, 22D, and passing through the assembled legs 22C, 22D, through leg sockets 28C, 28D, and top openings 32C, 32D in the fastening hub 25. The ridge pole 21 and legs 22A-22D may be fabricated of a lightweight aluminum alloy or other metal. In other exemplary embodiments, each of the ridge pole 21 and legs 22A-22D may comprise a single-length integrated structure fabricated of plastic, fiberglass, wood, or other suitable material. In still further embodiments, the exemplary ridge pole 21 and legs 22A-22D may comprise multiple telescoping sections with one or more spring-loaded detents and longitudinally-spaced holes enabling ready and convenient length adjustment.

As best shown in FIGS. 3 and 4, a flexible suspension strap 40 is centrally attached to the top fastening hub 25, and extends downwardly from the hub 25 between the equally-spaced diverging pod legs 22A-22D. In one exemplary embodiment, the flexible strap 40 comprises a folded length of fabric webbing threaded through slots of a rectangular metal slide 41, and folded upon itself to form first and second overlying strap sections. In one embodiment, the overlying strap sections are machine-sewn at various attachment points to form an upper (folded) pole stop 42 and a multi-looped free end 44. The metal slide 41 engages a top surface of the fastening hub 25 adjacent a center hub opening 45, while the looped free end 44 of the strap 40 extends through the hub opening 45 and towards the ground. The loops “L” in the suspension strap 40 are formed between adjacent attachment points and corresponding secured (or unsecured) folded portions to create a “shingle like” design or profile. The exemplary suspension strap 40 may have between 4 and 8 longitudinally adjacent (or spaced) loops “L”, and may be constructed of an 8-ounce, 0.75 inch, flat nylon or polyester material. The multiple loops “L” allow the hammock 11 to be hung at different selected points along the cooperating suspension straps 40 of pod assemblies 20, 20′, thereby adjusting the elevation and tension of the hammock 11 as desired by the user.

The space formed with the suspension strap 40 between the upper pole stop 42 and first hammock attachment loop “L1” is designed to receive and locate a vertically-slotted end cap 51A, 51B of the horizontal ridge pole 21. The slotted caps 51A, 51B are located at opposite ends of the ridge pole 21 and function to secure the ridge pole 21 to the suspension straps 40 of pod assemblies 20 and 20′, such that the ridge pole 21 is freely suspended just below respective top fastening hubs 25 of each assembly 20, 20′ The narrow slot 52 in each end cap 51A, 51B holds the pole end in position along a length of the suspension strap 40 thereby preventing the ridge pole 21 from sliding upwardly towards the fastening hub 25 and downwardly beyond the hammock attachment loops “L”, The strap 40 may be readily inserted into the cap slot 52 through an offset vertical opening 53 (FIG. 4) formed in the face of the cap 51A, 51B.

Referring again to FIG. 1, with the exemplary hammock stand 10 assembled as described above, opposite ends of the flexible hammock 11 are attached to selected loops “L” of the suspension straps 40 of pod assemblies 20, 20′ using the metal karabiners 12. When the hammock 11 is occupied by a user, the suspended ridge pole 21 may increase the overall stability of the stand 10 while preventing the weight of the user from tipping the pod assemblies 20, 20′ inwardly towards each other. Additionally, the legs 22A-22D of each pod assembly 20, 20′ may comprised enlarged bowl-shaped footpads 61 best shown in FIGS. 1, 2, 5 and 5A. The footpads 61 may further increase stability of the hammock stand 10 when occupied, and may help prevent the stand 10 from sinking into soft ground. A looped anchor cord 62 may also be attached to each foot pad 61, and designed to receive a ground stake 63 or other anchoring device.

In exemplary embodiments, the present hammock stand 10 may be further reinforced by using cooperating base stabilizer cords 71 and 72. As best shown in FIGS. 1, 2, 5 and 5B, the first stabilizer cord 71 is attached to an outside two of the rigid stand legs 22A, 22B, while the second stabilizer cord 72 attaches to an inside two of the stand legs 22C, 22D. The first and second stabilizer cords 71, 72 are then releasably joined together at a center point between the four legs 22A-22D using a buckle fastener 75. When fastened, the stabilizer cords 71, 72 cooperate to pull or curve the stand legs 22A-22D slightly towards one other. This pre-loads the legs along a generally X-shaped cord path, thereby increasing the overall load capacity of the hammock stand 10.

FIG. 6 shows various components of the exemplary hammock stand 10 including pod assemblies 20, 20′, the ridge pole 21, and ground stakes 63 disassembled and ready for insert into a carry case 80 for convenient transport. When packaged inside the carry case 80, the entire assembly may weigh only 15 pounds or less.
