BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENT

The hammock described can fold up into a bundle of sticks and covered with a bag, or wheeled around for easy transportation. The plurality of elongated members formed as sticks provide structure to the folding hammock. The hammock has a rectangular figure eight structure made of folding members. The folding members comprise seven separate segments analogous to a seven segment display. The seven segments include a front segment toward the feet of the hammock, a rear segment toward the wheels of the hammock, a middle segment between the front segment and the rear segment, and a pair of right segments and a pair of left segments. The pair of right segments include a right rear segment and a right front segment. The pair of left segments include a left rear segment and a left front segment. Each segment is made of a crossing scissor structure where the members are in pin joint swivel connection having ‘x’ shaped configuration. Additionally, a pair of front inside connection members and a pair of rear inside connection members are connected to each of the pair of right segments and the pair of left segments.
The canopy extension member 10 extends from a corner post such as rear corner post 30. A line clip 20 provides a clip connection 31 with a line that extends above the user. The line may be formed in the shape of a sheet such as a fabric shade. The canopy extension member has telescopic extension from a corner post such as rear corner post 30. The line clip 20 can be mounted on a line clip hook 21 and terminate with a line clip carabiner 22.
When folding, the inside connection members swivel on a top bracket such as rear inside connection member top bracket 32. The rear inside connection member 40 swivels upward and the rear inside connection member bottom clip 44 detaches from the rear bottom clip connection area 43. The rear inside top connection joint 41 is formed on the rear inside connection member top bracket 32. The rear inside bottom connecting joint 42 swivels in relation to the side rear double member 60. The deployed angle of the side rear double member 60 and the rear inside connection member 40 increases beyond 180° when the folding hammock is folding into a folded position. The rear inside connection member bottom clip 44 engages with the rear bottom clip connection area 43 in a snug fit and can be attached and reattached. The rear bottom clip connection area 43 can be formed as a sheet or sleeve disposed over the rear corner post 30. The side rear double member 60 is formed of a pair of members parallel to each other and sandwiching the rear inside bottom connection joint 42 as well as sandwiching the side front single-member 90. Also sandwiched is the side rear single-member 61 so that in combination the members hold up the hammock bed 50 which is formed and a pair of sections, namely a rear hammock bed section 51 and a front hammock bed section 52.
The corner post connection 33 is in swivel connection with the corner post 30. The lower portion of the foot 130 may include a foot concave 131 for gripping the ground. The foot is preferably in swivel connection on a foot connection 132.
The line held on the line clip 20 forms four corners in a rectangular profile which can be filled in with a net such as mosquito netting, or a shade. The line has a line corner, and forms a line front edge 72, a line rear edge 73 and a line side edge 74. The canopy 80 is placed over the line. The line can allow a user to attach additional objects to the hammock such as camping equipment like lights or a compass.
The front inside connection member 100 is in similar configuration to the rear inside connection member 40 in that it is connected at a front inside top connection joint 101 to the front corner post 110 just like the rear inside connection member 40 was connected at a rear inside top connection joint to a rear corner post. The front inside connection member 100 also swivels upward during folding on the top connection joint 101 so that it rotates on front inside bottom connection joint 92 and rotates on the front inside top connection joint 101. When the front inside connection member 100 rotates upward, it releases the front inside connection member bottom clip 104 from the front corner post 110. Analogous to the rear construction, the front inside top connection joint 101 is connected on the front inside connection member top bracket 102. The front inside connection member bottom clip 104 is released and reattached to the front bottom clip connection area 103.
The front segment 120 includes a front segment first member 121 and a front segment second member 122 mounted in a swivel connection. The segments are not necessarily attached in a coplanar fashion, but can be offset or bent for better folding. Similarly, the rear segment includes a rear segment first member 123, a rear segment middle joint 125 connecting a rear segment second member 154. The rear segment is connected at its bottom portion to the side rear single-members 61 at a lower right rear corner connection 128 and a lower left rear corner connection 129. The rear segment is connected at its top portion to the upper left rear corner connection 137 and the upper right rear corner connection 156. The upper left rear corner connection 137 and the upper right rear corner connection 156 connect to the inside bottom connection joint 42 or alternatively to the corner post.
The middle segment 140 includes a first middle member 141 and a second middle member 142 connected at a middle middle joint 143. At each of the four corners of the middle segment 140, a bracket connects to the middle connections which include the side bottom middle connection 91, as well as the side top middle connections. The entire structure thus is foldable from a deployed position into a collapsed position where the sticklike rod members are substantially all parallel to each other.
