Abstract:
A tent has a flexible canopy, a floor and a series of inflatable tubes serving as frame hoops. The tubes are fastened removably to the tent using sleeves that open along a longitudinal slit and hook and loop pile fastener closures for closing the sleeves on the tubes.

Description:
This application is a continuation of application Ser. No. 632,999, filed Dec. 24, 1990. 
    
    
     FIELD OF THE INVENTION 
     The present invention relates to tents and more particularly to an easily transportable, pole-less tent with an inflatable frame. 
     BACKGROUND OF THE INVENTION 
     Various pole-less, inflatable tents have been designed in the past. A number of these have had inflatable walls and floors, which makes for a relatively heavy tent and requires a great deal of inflating air. When a chamber is punctured in the field, it is difficult to repair. Other tents have used an inflatable tube frame concept. The inflatable tubes have relatively thick walls in order to inhibit damage, and are therefore relatively stiff and heavy. The tubes are also permanently fastened to the tent so that any damage to a tube is difficult or impossible to repair. 
     The present invention is concerned with a novel tent of the inflatable frame type. 
     SUMMARY OF THE INVENTION 
     According to the present invention there is provided a tent comprising: 
     a flexible canopy; 
     a plurality of inflatable tubes independent of the canopy; and 
     tube holding means for detachably securing the inflatable tubes in an inflated state to the canopy for supporting the canopy in an erected condition. 
     Preferably, the tube holding means are flexible sleeves secured to the tent canopy. Each sleeve has an end-to-end opening along one side and sleeve fasteners for closing the sleeve. The preferred sleeve fastener is the hook and loop fastener material sold under the trademark &#34;Velcro&#34;. 
     The use of detachable tubes allows a very compact folding of the canopy for transport. The tubes themselves can be made of relatively thin wall material as they can be handled independantly of the canopy, thus minimizing the risk of damage. If damage does occur to a tube, it is relatively easy to fix by repairing the tube when removed from the tent or, where necessary, a replacement. The tubes may conveniently be fabricated from a flexible thermoplastic material. 
     Where the tubes are external to the canopy, they may be used to support a fly, which may be fastened to the sleeves.

     DETAILED DESCRIPTION 
     Referring to the accompanying drawings, especially FIG. 1, there is illustrated a tent 10 having a polypropylene floor 12 and a canopy 14 secured to the edge of the floor. The canopy has two walls 16 and a peaked roof 18. At one end of the tent is a door 20 with an internal screen or fly bar 22 separated up the vertical center by a slide fastener 24 and secured to the top edge of the floor by slide fasteners 26. The weather door itself is a part of the canopy and is closed using door ties 28. 
     The tent is held in an erect condition by three frame hoops 30 that stretch the canopy into an erect condition as illustrated in FIG. 1 and stretch the floor from side to side. Two main guylines are included, at the front and back of the tent, connected to the canopy adjacent the ridge of the tent. This tensions the canopy from front to back and also ties down the relatively light tent to the ground. The guyline 32 at the front is pegged to the ground using a conventional tent peg 34. 
     As illustrated in FIG. 1, the tent is equipped with a fly 36 that is supported above the walls and roof of the canopy by the frame hoops 30. 
     At each corner of the tent, and halfway along each wall 16 is a cup-like boot 38 that is upwardly open. The boot is secured to the tent canopy and floor. Aligned with the boots 38 are sleeves 40 positioned along the front and back edges of the walls 16 and midway along the walls. Roof sleeves 42 are likewise positioned at the front and back edges of the roof 18 and midway along the roof. 
     The boots 38 and the sleeves 40 and 42 serve to retain three inflatable tubes 44 of flexible vinyl plastic on the tent to provide the three frame hoops 30. The inflatable tube has a profile that follows that of the erect canopy. Its end are seated in the associated boots 38. 
     The sleeves 40 and 42 are each made of a sheet 46 of textile fabric material secured to the canopy. The sheet has two edges 47 and 48 that define an opening 49 of the sleeve as illustrated most particularly in FIG. 2. The sleeves are held closed with the edges overlapping as illustrated in FIGS. 1 and 3 using sleeve closures 50 spaced along each of the sleeve sheets 46. 
     Each sleeve closure includes a strip or belt 52 secured to the sheet along one of the edges 48. Along the opposite edge 47 are mating slots 54 through which the belt 52 pass to draw the sleeve closed around a tube 44. The belt 52 is provided with &#34;Velcro&#34; patches 56 and 58 so that when it is fed through the slot 54 it may be folded back on itself to secure the sleeve in a closed condition. 
     The tubes 44 and their retaining sleeves 40 and 42 are located externally of the canopy 14. They are used for supporting the fly 36 away from the canopy walls and roof so that there is a clear air space between the fly and the canopy itself. The fly is retained in position using mating fasteners 62 on the fly and the sleeves. The fasteners may be interlocking, corrosion resistant nylon fasteners. 
     While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
