Description

BRIEF DESCRIPTION OF THE INVENTION

The present invention relates to a portable tent and more particularly to a portable tent which can be folded into a compact package without dismantling any structure.

According to the invention, a structural tent is provided in which a base rectangle consists of six structural members of approximately the same length hingedly attached to each other, together with a plurality of U-shaped members rotatably attached to the base rectangle at the center points of the two longest legs, so that the entire structure can be folded into a package the length of one of the structural members. A door is provided by discontinuing two of the U-shaped members, one of which provides one side of the door and is continued in a vertical direction to hingedly attach to one of the structural members of the base rectangle. This vertical section is adjustable in length to effect an overall symmetry after erection. The second U-shaped member is discontinued and brought in at right angles to the vertical section of the first discontinued U-shaped member as will be appreciated by reference to the detailed description below. The entire structure is covered with a pliable covering such as canvass with a zippered door cutout and preferably a screened window cutout.

An object of the present invention is the provision of an improved portable tent.

Another object of the invention is the provision of a portable tent which can be set up and taken down without disturbing any structural coupling.

DETAILED DESCRIPTION OF THE DRAWING

Referring to FIG. 1, the portable tent of the present invention is shown in a completely folded condition at 11. Referring to FIG. 2, tent 11 is shown in a partially unfolded condition. Referring to FIG. 3, tent 11 is shown in a further unfolded position having a canvass covering 12 with a zipper 13 in its bottom section and a door zipper 14 in a front section.

Referring to FIG. 4, tent 11 is shown in its fully erected condition with door zipper cutout 14 and floor section V-shaped zipper 13 in canvass covering 12. Floor frame member 16, together with structural members 17 and 18 are pivotally connected to pivot section 19.

Referring to FIG. 5, the entire framework is shown having a rectangular floor section consisting of structural elements 16, 21, 22, 23, 24 and 26. Elements 24 and 26 are hingedly attached at 27 and have a limit line 28 coupled around hinge 27. Members 26 and 16 are likewise hinged at 29, having a limit cord section 31 coupled between them and a round hinge 29. Floor structural members 16 and 21 are hingedly coupled to hinge section 19. Floor structural members 21 and 22 are hingedly attached at 32 and are coupled together with limit cord 33. Floor structural members 22 and 23 are hingedly attached at hinge 34 and are coupled together via limit line 36. Floor structural members 23 and 24 are hingedly attached to hinge member 37.

Structural member 38 is hingedly coupled to hinge member 37 and to structural member 39 via hinge 40. Structural members 38 and 39 are also coupled via limit line 41. Structural members 39 and 17 are hingedly attached at 43 and are coupled together via limit line 44. Structural member 46 is hingedly coupled to hinge member 37 and to structural member 47 at hinge 48. Structural members 46 and 47 are also coupled via limit line 49. Structural members 47 and 18 are hingedly attached at 51 and are coupled together via limit line 52. Structural member 53 is hingedly attached to hinge member 37 and hingedly coupled to structural member 54 at 56. Structural members 53 and 54 are also coupled via limit line 57. Structural members 54 and 58 are hingedly attached at 59 and are coupled together via limit line 61. Structural member 58 also is hingedly attached to hinge member 19. Structural member 62 is hingedly attached to structural member 63 at 64 and coupled to structural member 63 via limit line 66. Structural member 63 is hingedly attached to structural section 67 at 68. Structural member 67 is hingedly attached to structural section 69 at 71. Structural section 69 is coupled to structural section 72 via strap guides 73 and 74 and pin lock 76. Structural section 69 is also hingedly attached to structural section 77 at 78. Structural section 77 is hingedly attached to structural section 80 at 79. Structural section 78 is hingedly attached to structural section 81 at 82. Structural section 81 is also hingedly attached to structural section 83 at 84 and is coupled to structural section 83 via limit line 86. Structural section 72 is pivotally attached at 75 to structural section 23.

All of the adjacent hinged sections are coupled with limit lines as follows: limit line 91 between hinge 27 and 40; limit line 92 between hinges 51 and 59; lmit line 93 between hinges 48 and 56; limit line 94 between hinges 29 and 44; limit line 96 between hinges 59 and 64; limit line 97 between hinges 64 and 84; limit line 98 between hinges 84 and 32; limit line 99 between hinges 34 and 82; limit line 101 between hinges 82 and 68; and, limit line 102 between hinges 68 and 56. Some of these limit lines are hidden behind structural members but it is to be understood that they are present between adjacent hinges.

OPERATION

Referring back to all of the drawings, it can be seen that the structural members of the frame are all of substantially equal length to facilitate a folding in three parts as shown more clearly in FIG. 2, with sections 11A, 11B and 11C. One part would be all of the structural members at the top of the tent and those parallel to it and the other section would comprise all of the structural members on the other side of the tent. Hence, when it is desired to erect the tent, the sections 11A, 11B and 11C, are merely unfolded, and the structural members pivotally attached at 19 and 37 are then rotated into the position shown in FIG. 5. The limit lines 91 through 102 keep the vertically disposed structural members at a desired separation and the limit lines such as 28, 31, 33 and 36, limit the angular separation of adjacent structural members.

When disassembled, the canvass covering 12 folds in an accordion manner between adjacent structural members. It has been found that a V-shaped zippered section 13 facilitates the final folding of sections 11A, 11B and 11C, into a compact position shown in FIG. 1. This final folding is shown in FIG. 11. Referring to FIG. 5, a door section indicated at 14 in FIG. 4 is formed between structural members 53 and structural sections 72, 69 and 67. The reason for the added hinge section 67 and the slidable relationship between sections 69 and 72 can be seen with reference to FIGS. 7 and 8. In order for the tent to fold in the fashion shown in FIG. 8, sections 77 and 69 must be pushed up via guiding straps 73 and 74 to where their ends are even with the ends of the rest of the structural members. In order to effect a symmetrical disposition of the horizontal structural member 63, section 67 is necessary to bring it into alignment. The same is true with section 80 and section 81. These make possible an unobstructed rectangular opening via zipper 14 to form an entrance space to the structure.

FIG. 6 illustrates locking pin 76 which locks sections 69 and 72 together in the erect position so that portions of the tent will not collapse. When it is desired to collapse the tent, locking pin 76 is removed and sections 69 and 72 can be moved relative to each other as shown in FIGS. 7 and 8.

It should be understood, of course, that the foregoing disclosures relates to only a preferred embodiment of the invention and that it is intended to cover all changes and modifications of the example of the invention herein chosen, for the purposes of the disclosure, which do not constitute departures from the spirit and scope of the invention.
