An improved tent covers a hammock suspended from a pair of upright members by suspending means at each end of the hammock. The tent is formed from top and bottom portions that interact to provide a tent opening that prevents the entry of atmospheric precipitation when the tent opening is open. The tent also provides improved visibility from inside the tent, by enabling a horizontal field of view.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application is a nonprovisional of, and claims benefit of priority under 35 USC 119 from, U.S. Ser. No. 60/908,475, filed 28 Mar. 2007, which is incorporated by reference as if fully recited herein.


TECHNICAL FIELD
The present invention relates to an improved hammock tent having an improved means of suspending a hammock.
BACKGROUND OF THE ART
The inventor herein is the inventor and owner of U.S. Pat. No. 7,020,915 (“the '915 patent”), issued 4 Apr. 2005, which is incorporated by reference as if fully recited herein. As shown in FIGS. 5 and 6 of the '915 patent, the hammock tent 60 comprises overlapping sections that completely surround the hammock 1. FIGS. 5 and 6 also show flap 69 that serves as a door. The tent 60 is supported by a supporting system having a ridge support, side supports and suspension supports.
Referring to FIG. 6 of the '915 patent, the door 69 of the tent 60 is located in the inclined upper portion of the tent 1. As a result, the occupier of the hammock cannot enter or exit the hammock, or leave the door open, without potential atmospheric precipitation entering the tent. Also, when the door is open, the field of view of the occupant is limited to an upward direction.
As shown in FIGS. 10A and 10B of the '915 patent, the hammock 1 is connected to suspending means by way of cargo hook 90. The cargo hook 90 is also connected to suspending strap 99 as described in FIGS. 9A and 9B. The suspending strap 99 is secured to an upright structure by means of cam buckle 200, as depicted in FIGS. 11 and 12.
In order to suspend the hammock, first the hammock and the suspending strap must be attached to the cargo hook. Second, the suspending strap must be wrapped around the structure and then fitted into the slot of the cam buckle. Accordingly, a simpler method of suspending the hammock is preferable.
SUMMARY OF THE INVENTION
The present invention provides an improved tent constructed such that no atmospheric precipitation can enter the tent when the tent door is open. This allows the hammock occupier to keep the door open, as well as enter and exit the tent without exposing the hammock to atmospheric precipitation. In addition the present invention provides improved visibility from inside the tent, by enabling a horizontal field of view.
The tent of the present invention consists of two portions, a top portion and a bottom portion. The bottom portion fits around the bottom of the hammock. The bottom portion is secured to the hammock by means such as ties, snaps or hook and loop fastener, such as that available commercially under the brand name VELCRO®. The bottom portion preferably contains vents at both ends.
The top portion fits overtop the tent support structure taught in the '915 patent and is equipped with means such as ties, snaps or hook and loop fastener, such as that available commercially under the brand VELCRO® to secure it to both the bottom portion as well as the side supports of the supporting system. When both the top and bottom portions are secured in place, a tent structure is constructed with an opening on each side of the hammock.
The opening in the tent is located under the inclined top portion of the tent, such that the top portion overhangs the opening. Therefore, potential atmospheric precipitation falling on the tent rolls down and off the sides of the top portion, without entering the tent through the opening.
The opening is provided with a door to permit an occupant of the hammock to close the tent. The door consists of two parts: a bug screen and a curtain that can be operated independent of one another. The bug screen and curtain can also be attached to one another by means such as ties, snaps or hook and loop fastener, such as that available commercially under the brand VELCRO®, and be operated as one unit.
Both the bug screen and curtain consist of a single piece of material extending from one side of the hammock to the other, covering both lateral openings of the tent. The bug screen and curtain are fitted through the space between the hammock and the bottom portion of the tent. Accordingly, when the hammock occupier opens the door, the bug screen and curtain can simply be dropped and stored therein.
In order to close the door, the hammock occupier can attach the bug screen and curtain to the inside of the two side-supports by means of ties, snaps or hook and loop fastener.
The present invention also provides an improved means of suspending the hammock to an upright structure. The improved means of suspending the hammock comprises a cam buckle that is permanently attached to each end of the hammock and which replaces the cargo hook of the '915 patent.
Also attached to the cam buckle is one end of the suspending strap. The other end of the suspending strap is attached to a cargo hook. In order to secure the hammock to an upright structure the suspending strap is wrapped around the structure and the cargo hook is secured to a D-ring through which the suspending strap is fitted. Alternatively, a snap or open hook may be used instead of the cargo hook to secure the suspending strap to the upright structure. The improved means of suspending the hammock makes the installation of the hammock much simpler and faster than the existing method.
Further features of the invention will be described or will become apparent in the course of the following detailed description.
