Adaptable hammock shelter

Abstract

An exemplary hammock shelter may provide unique ergonomic features, such as slits and pockets that permit a user's arms and legs to hang below the hammock. This arrangement of features may advantageously provide the user a flatter posture with improved comfort and ergonomic support. An exemplary hammock shelter may be used alone or multiple sheet or blanket accessories may be attached to provide insulation and comfort to the user over a range of temperatures. In some examples, insect and weather barrier canopies may be attached or otherwise affixed to an exemplary hammock structure to provide protection to the user from insects and weather elements.

DETAILED DESCRIPTION

(18) In the following description of the various embodiments, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration various embodiments in which features may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made.

(19) In FIG. 1, an exemplary hammock 1 is demonstrated. By way of demonstration and not limitation, the hammock 1 may be made of durable fabric or netting. Each end of the hammock 1 material is attached to a v-ring 2 or d-ring or other suitable piece of hardware. At each end of the hammock 1, an anchor rope or anchor strap 3 is attached to the v-ring 2 and to a tree or other support structure or element to suspend the hammock 1 in a generally horizontal matter between the two supports.

(20) One major drawback to current hammocks is that the curvature of the hammock causes a few ergonomic discomforts. Current hammocks, when occupied by a user in a supine position, tend to support mainly the heels of the user and generally provide little to no support to the back of the user's knees. The curvature of current hammocks may also cause the shoulders of the user to be drawn inward (“shoulder squeeze”). Accordingly, hammock 1 of the present invention may have slits 1S in the hammock 1. The slits 1S advantageously allow the user's arms and lower legs to pass through the hammock support fabric into pockets 1P below the hammock 1. As a result, the posture of the user will be closer to flat, the back of the user's knees will be supported, and shoulder squeeze is effectively eliminated. The slits 1S and pockets 1P thereby advantageously improve comfort and ergonomic support.

(21) Referring now to FIG. 2, one or more sets of separating fasteners 5 are sewn to the hammock 1. By way of demonstration and not limitation, FIG. 2 demonstrates the fasteners 5 as zippers. These separating zippers 5 allow accessories, such as insulative sheets and blankets, to be attached to the hammock 1 to provide the user with comfort over a range of temperatures. According to the example shown in FIG. 2, the lower blanket 6 may be positioned beneath the user and upper blanket 7 may be above the user. Furthermore, an insulative and/or heat reflective blanket (not illustrated) may be attached under the hammock 1. When blankets or sheets are attached to the hammock, they assume the same shape as the hammock. This allows easy entry and exit of the user from the hammock and blankets. This is a significant advantage over prior art that uses an unattached sleeping bag within the hammock. An unattached sleeping bag bunches together at the bottom of the hammock and makes entry and exit difficult. The easy entry and exit of the present system also presents a safety advantage.

(22) Referring now to FIGS. 11,14,15,16, one or more accessory canopies 15 may be attached to the hammock 1 to enclose the hammock 1 and the user. For example, an insect barrier canopy, which may be made of a fine mesh material or other appropriate material, may be attached to protect the user from insects. In another example, a weather barrier canopy, which may be made of a water repellant material or other appropriate material, may be attached to protect the occupant from insects and weather elements. Additionally, a hybrid canopy, made of water repellant material or other appropriate material, having windows made of fine mesh material and closable window covers, may provide versatile protection to the user.

(23) Turning now to FIGS. 3-6, if an accessory canopy 15 is to be used, a taut strap 8 may be attached to the hammock 1. The tip of the v-ring 2 (or other appropriate structure) at each end of the hammock 1 may be passed through a hardware link 9 (or other appropriate structure) at each end of the taut strap 8. The link 9 may be of a geometry that the v-ring 2 cannot pass completely through the link 9. According to the examples shown, one or more pulley-type links (10A,10B,10C) may be fixed between sections of the exemplary taut strap 8. In these example, the taut strap 8 may be shorter in length than the hammock 1, which thereby limits the distance between the v-rings 2 of the hammock 1. Therefore, the hammock 1 will consistently hang below the taut strap 8 with the same curvature when set up.

(24) According to the examples shown in FIGS. 14-16, the upper edges of the canopy 15 may be joined to each other in a scroll fold 16 at the canopy head end 15H and the canopy foot end 15F. FIG. 15 illustrates the scroll fold 16 at the canopy foot end 15F, in the form of a flattened scroll-type fold. The canopy foot end 15F may be sewn to the taut strap 8. The canopy head end 15H may be free to slide along the upper side of the taut strap 8. In FIGS. 7-14, an exemplary canopy pull strap 11 forms a loop around pulley links 10A and 10B. The canopy head end 15H may be fixed to the upper face of the canopy pull strap 11. Referring now to FIGS. 14-16, in the open configuration (FIG. 14), the upper edges of the canopy 15 may be parted and hanging slack along the sides of the hammock 1. To close the canopy 15, the user, while lying supine in the hammock 1, may pull the underside of the canopy pull strap 11 toward the hammock foot end 1F. This movement, by pulley action through the pulley links 10A and 10B, may cause the canopy head end 15H to slide toward the hammock head end 1H. As the canopy head end 15H moves away from the canopy foot end 15F, the resulting tension may draw the upper edges of the canopy 15 together into the same scroll fold as the canopy ends 15H and 15F. The closed canopy encloses the hammock 1 and user, and forms a peak above the taut strap 8. Scroll folds 16 at each of the canopy foot end 15F and canopy head end 15H may have enough turns to inhibit insect/water intrusion. The closure system described above provides for rapid and easy opening of the canopy with, with no need for a user to sit up and wrestle with lengthy zippers in the dark. This ease of opening therefore presents a significant safety advantage over current hammock shelter systems.

(25) In summary, aspects of the present invention relate to an adaptable hammock shelter with unique ergonomic features, and accessory attachments to adapt the hammock to various climates and conditions. One of ordinary skill in the pertinent arts will recognize that, while various aspects of the present invention are illustrated in the FIGURES as separate elements, one or more of the elements may be combined, merged, omitted, or otherwise modified without departing from the scope of the present invention.
