Turning now to the drawings and more particularly to figure 1 we have a perspective view of a tent 20 having a wind resistant tubular frame 22. Most generally the tent 20 comprises: a frame 22 having a) multiple frame legs 24, each leg 24 having a lower portion 28 lockingly hinged to an upper portion 26, wherein the lower portion 28 can be swung open from a storage position in which the upper portion 26 and lower portion 28 are adjacent to each other, and then locked in an open operable position; and, b) a crown 30 to which the an inner end portion of the upper portion 26 of each one of the multiple legs 24 is hinged generally laterally thereto, wherein the legs 24 can be laterally rotated from a storage position in which they are adjacent to each other to an operable, spaced apart position in which the frame legs 24 radiate outwardly from the crown 30; and, a canvas 32, shaped to cover one of an inner and outer sides of the frame 22.

Figure 2 is a partial perspective view taken from inside the tent 20 shown in figure 1 , looking up at the crown 30, which is used to hingably attach an upper portion 26 of each one of the multiple legs 24. The crown 30 most preferably comprises two spaced apart parallel members 34 and the lateral hinges 36 comprises bolts 38 extending between the parallel members 34 and through an inner end portion of each of the frame legs 24. Most preferably the two spaced apart parallel members 34 comprise planar members 40 attached together by spacers 41 and wherein the hinge bolts 38 are spaced along a central portion of the planar members 40.

In the most preferred embodiment the canvas 32 is adapted to cover an inner side of the frame 22, and the tent 20 further comprises canvas attachment means 42, for attachment of the canvas 32 thereto. Most preferably the frame comprises 22 square tubing 23 and the canvas attachment means 42 comprises a C shaped channel 44, having a back attached to an inner side of the square tubing 23, and a zig-zagged wire 46 positioned therein to clamp the canvas 32 therebetween. Most preferably the upper 26 and lower frame leg portions 28 are lockingly hinged with lever clamps.

Figure 3 is an enlarged perspective view of a locked top corner hinge 50 used to hingably lock the upper 26 and lower frame leg portions 28 are lockingly with a lever clamps 52. Lever clamps 52 are ideal to lock the upper 26 and lower 28 leg portions together. When the frame 22 is assembled, and comprises 2" aluminum tubing, with a span of 14' between the bottom portion of the legs 28, a weight of 500 pounds can be hung from the crown 30 quite safely. Referring back to figure 1 in the most preferred embodiment of the invention the tent frame legs 24 further comprise stakes 60 and ground plates 62 having stake openings 64 therethrough, said ground plates 62 attached to a bottom side portion of the lower portion of each leg 28, so that the legs 24 can be staked to the ground 66 for stability in high wind. Most preferably the canvas extends 32 along the ground so that sand bags or product stored (neither shown) in the tent 20 can be used to weight the bottom portion of the canvas 32 on the ground 66 and thereby prevent air entry.

Figure 4 shows the crown 30 shown in figure 2 further comprising a door side leg 70 which laterally swings between adjacent frame legs 24. In a preferred embodiment of the invention the tent further comprises a door side leg 70 for opening an entire segment of the tent between two tent frame legs 24 for convenient entry of large equipment, said door leg 70 rotably positioned between two spaced apart frame legs 24, wherein the door side leg can be rotated between an open position and a closed position adjacent to a frame leg 24 on one side of the door and wherein canvas 32 attached to the door side leg 70 is pulled and held in a closed position when the leg is rotated to the closed position. Most preferably the door side leg 70 comprises an upper portion 26D and a lower portion 28D lockably hinged together, and wherein an upper portion of the door side leg 26D comprises an elongate laterally swinging hinge link 86 having an inner end portion laterally hinged between a front side portion of the planar members 40 by a bolt 38 and an outer end portion laterally hinged to an intermediate portion of the door side leg 26D, said laterally swinging hinge link 86 and the outer end portion of the door side leg 70 having a combined length generally equal to the length of an upper portion of a frame leg 26, whereby the door side leg 70 is able to swing to a position longitudinally adjacent to the tent frame leg 24. As shown in figure 4 an inner upper portion of the door side leg 70 may be provided with a handle 72 which is pivotably attached thereto for movement of the door side leg to open and close a segment of the tent 20 for entry or removal of large materials or equipment (neither shown). The handle 72 shown in figure 4 comprises a long tube 74 which is releasably held (not shown) adjacent to the door leg 24. This long tube 74 is also useful in maintaining the crown 30 in an elevated position when erecting the tent 20.

Figure 5 shows a front view of the tent 20 having a lower door leg peg 82 attached to a frame leg 24 and a clamp 52 to maintain the upper portion of the door leg 70 against the frame leg 24. In a preferred embodiment the lower portion of the door leg 28D is shorter than the lower portion of the frame leg 28, and further comprises an upright peg 82 non-removably attached to a lower portion 28 of the adjacent frame leg 24. The peg 82 receives the lower end portion 28D of the door leg 24D thereover. A door clamp means 84 maintains the door side leg 24D closely adjacent to frame side leg 24, thereby releasably holding the door leg 70 in a tightly closed position. Most preferably the door clamp means 84 comprises a lever clamp 52. A zippered door opening 83 allows an individual to enter the tent 20 rather than entering by unclamping and rotating the lower portion of the door frame leg 28D. Entry by rotating the door frame leg 28D is intended for convenient entry of large items (loaded on skids) and bulky equipment. When the lower portion of the door frame leg 28D is fully open a skid steer loaded can drive into the tent 20. In the most preferred embodiment of the invention the frame 22 comprises aluminum, and a planar plastic bushing 87 (see figure 4) is attached to upper and lower sides of the legs 24, between the legs 24,70 and planar members 40 to facilitate movement and prevent wear. The tent 20 has four frame legs 24, each having a lower portion 28 which is 7Ί0" high, so that the folded tent 20 can be carried in a pickup truck with a closed tailgate. The tent is 9' high.

A method of erecting a tent 20 comprises the following steps: providing a tent 20 as most generally described above; rotatably separating the hinged and adjacent upper and lower portions of the frame legs 24, and clamping the upper 26 and lower 28 legs 24 in the open position; and rotatably separating and spacing apart the open legs 24 whereby the tent frame 22 attains a standing position.
