  • Patent number: 8745782
    Abstract: A portable, reversibly-extensible hammock has a foldable structure for supporting a substantially planar support surface. The hammock can be folded for transportation or storage, and can be shifted to an extended configuration to create a rectangular structure similar to a cot or hammock frame. A dual-purpose tensioning strap joins the support surface to the foldable structure and increases the structural integrity of the structure by urging top portions of leg members toward a center point of the rectangular structure.

  • Patent number: 8528131
    Abstract: An improved sleeping or camping cot construction is provided in which the end rails of the cot frame are pivotally mounted along their center along a channel member so that downward forces on the cot in its normal operating position improves the stability of the cot by forcing the end rails into engagement with the channel member. The channel member also encloses the pivot points of the end rails from inadvertent contact a user during the pivot operation of the end rails.

  • Publication number: 20120047649
    Abstract: A portable and collapsible cot structure comprises a fabric web, a frame, and a plurality of folding legs pivotally attached to the frame. The cot structure is collapsible to a bundled condition to minimize the amount of space taken up by the structure during storage and transportation. The cot structure includes at least one locking assembly pivotally connected to a leg assembly for maintaining the cot in an open, set-up condition, wherein the locking assembly must be unlocked before the cot structure can be collapsed. The locking assembly includes a first pedal for locking the assembly and a second pedal for unlocking the assembly. Preferably, a downward force can be applied to operate either pedal, thereby facilitating quick and easy set-up and break down of the cot structure without compromising safety, consuming too much time, or requiring undue effort.
