Definitions

  • Outdoor portable shelters such as tents have been used to provide temporary shelter and protection from the sun, wind, precipitation, harsh temperatures, condensation, biting insects, and other outdoor elements for workers, equipment, and outdoor enthusiasts for many years. Aside from protecting an interior volume from the elements, modern day shelters should be quick to set-up and portable. To be portable, the temporary shelter should be lightweight so it is easily carried to a proposed site as well as easy to assemble and disassemble.
  • Most conventional tents are configured with a floor that is made of a heavier material than that used for the portions of the tent that will not be in contact with the ground.
  • the weight of the heavier material used to construct the floor of these tents makes up a significant portion of the overall weight of the tent.
  • the floor is often configured with loops at fixed locations along the perimeter of the tent for receiving a stake that sets or fixes the floor of the tent to the ground.
  • These floors are often configured with additional hardware and or loops for locating and receiving an end of a flexible support rib. Once all the support ribs are flexed and set at their designated receiving ends in or near the perimeter of the floor, the upper panels of the tent can be supported from the ribs.
  • Some conventional tents use sleeves formed or otherwise attached to the outer surface of the upper panels of material to suspend the tent.
  • Other conventional tents use hooks connected to tabs or other extensions that are sewn to the upper panels of the tent to suspend the tent under the support ribs.
  • Many of these conventional tents use a rain fly to further shelter the tent.
  • a rain fly protects the tent from harmful ultraviolet radiation from the sun.
  • a rain fly provides an additional barrier in the rain and snow, can help keep sparks from a fire or wood stove away from the exterior surface of the tent and when set up correctly can provide an insulating layer when it is cold.
  • Conventional rain flies are made from a relatively lightweight fabric made from man-made fibers (e.g., nylon, polyester) with canvas ties or other heavier fabrics used together with hook and loop fasteners for fixing the rain fly to support ribs. The fabric is often treated or coated with various waterproofing and fire resistant agents. When appropriate, a hole for a stove jack or vent will be formed with canvas or reinforced webbing.
  • a flexible and scalable base structure for floorless portable shelters and methods for constructing and using the same are invented and disclosed.
  • a base structure for floorless portable shelters includes a flexible loop and a plurality of rib intersections arranged along the flexible loop, each of the plurality of rib intersections forming an opening for receiving a respective end of a rib.
  • the flexible loop is arranged in a length that enables each of the rib intersections to be positioned to receive a corresponding end of a rib or other flexible member that supports the material of a rain fly or other cover in a desired configuration.
  • An alternative embodiment of a base structure for a floorless portable shelter includes a flexible loop having an adjustable length and a plurality of rib receiving members arranged along the length of the flexible loop. Each of the plurality of rib receiving members can be moved along the length of the flexible loop.
  • an even number of the rib receiving members can be suitably positioned to support any number of floorless portable shelters by setting the length of the perimeter formed by the flexible loop and moving each of the rib receiving members to an appropriate location along the flexible loop.
