Application November 6, 1956, Serial No. 620,753

4 Claims. c1. 135-3 The present invention generally relates to a novel concept in the construction of a tent and more particularly to a novel tent frame which is easily collapsible and disassembled for easy transport and storage but yet which is extremely sturdy in construction and provides an easily assembled tent frame which is automatically adjusted to tents with certain variations in size and which may be manually adjusted for substantially all size tents of the type generally known as an umbrella-type or pyramidal type.

One of the major problems insetting up the tent such as those used by hunters, campers or other persons is the support of the various portions of the tent under various weather conditions and still maintain a dependability as well as case of assembly and disassembly. One of the problems encountered is the size variations of the tent itself both from a manufacturing standpoint and also from the standpoint of shrinkage and stretching or enlargements caused by change in the moisture content of the canvas itself. Also the tent frame must be sufiiciently strong to withstand certain wind loads and also to provide a rigidity sufficient for support of the tent under various conditions. Accordingly, it is the primary object of the present invention to provide a tent frame which will solve the above-mentioned problems connected with tent constructions and also provide a tent frame which is extremely lightweight in construction and provided with a multiplicity of readily detachable elements all of which may be easily assembled and disassembled at the point of erection of the tent thus enabling the tent to be easily assembled and disassembled by a single person and which when completely assembled will provide the interior of the tent with no obstructions, such as a center pole in the interior of the tent thus permitting efficient utilization of the interior area thereof.

Other objects of the present invention will reside in its simplicity of construction, extreme ease of assembly adaptation for various sized tents and automatic adjustment for shrinkage and enlargement caused by rain or dry weather and the qualities which permit the tent frame to be readily adapted to its particular purpose.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:'

Figure 1 is a perspective view of a tent employing the tent frame of the present invention;

Figure 2 is a detailed sectional view of the cross bar construction; I

Figure 3 is a detailed sectional view of a supporting Figure 4 is a detailed sectional view of the peak post;

Figure 5 is a detailed sectional view of the leg taken substantially along section line 5-5 of Figure 6; and

Figure 6 is a perspective view of the tent frame with the tent being shown in phantom.

Referring now specifically to the drawings, the numetal 10 generally designates the tent frame of the prestzates Paw Q cut invention which includes'a first cross bar generally designated by thenumeral 12 and a second cross bar generally designated by thenumeral 14 each of which includes a depending post ofleg 16 at each end thereof with each of the posts orlegs 16 being identical and each of thecross bars 12 and 14 being identical.

Thecross bars 12 and 14 are disposed in intersecting relation with one being disposed immediately above the other. Each cross bar includes an elongatedtubular member 18 adjustably receiving a smallertubular member 20 having a plurality oftransverse apertures 22 receiving a fasteningpin 24 therethrough for eifectively adjusting the length of the cross bar. The other end of thetubular member 18 telescopically receives a thirdtubular member 26 disposed in abutting engagement with acompression coil spring 28 disposed within thetubular member 18. Aplug 30 is also disposed in thetubular member 18 and is provided with aslot 32 receiving aneye 34 on the end of thespring 28 with afastener 36 extending transversely of theslot 32 and through theeye 34 for securing thespring 28 to theplug 30 which in turn is secured to thesleeve 18 byinwardly extendingindentations 38 which effectively hold thewood plug 34 within thesleeve 18 and prevents thespring 28 from sliding outwardly of thesleeve 18.

The outer ends of thetubular member 20 and thetubular members 26 is provided with anend adapter 40 which is provided with a reduced portion 42 having ashoulder 44 thereon with a projectinglongitudinal pin 46 for reception in agrommet 48 in the tent cover which is generally designated by thenumeral 50. On the underside of each of theadapters 40 is a generallyspherical projection 52 in detachable frictional engagement with an uppertubular member 54 forming a portion of one of thelegs 16 thus detachably connecting thelegs 16 to thecross bars 12 and 14 inwardly of thelongitudinal pin 46 thus disposing thelegs 16 inwardly of the corner of thetent cover 50 and generally in contact with the corners thereof. Thespherical projection 52 and the inclinedupper edge 56 of the uppertubular member 54 will permit variation in the angle of thelegs 16 thus permitting thelegs 16 to be intimately disposed against the inside corner of the tent cover. Inasmuch as thecross arms 12 and 14 are independent of each other, these arms may readily adapt themselves to various shapes of tent covers in which thegrommets 48 are arranged at the upper corners thereof. The uppertubular member 54 of eachleg 16 is slidably received in a largertubular member 58 having a spring and plug therein which is identical to that described in connection with thecross bar 12. The lower end of the enlargedtubular member 58 receives a smallertubular member 60 having a plurality ofapertures 62 thereto for receiving thetransverse fasteners 64 for providing an initial adjustment of theleg 16 so that the spring disposed between the plug orblock 30 in thetubular member 58 may effectively urge the uppertubular member 54 upwardly whereby therubber foot 66 will engage the bottom of the tent cover for urging the same away from the cross arms thus tensioning the side walls of the tent cover in such a manner that they will be maintained in a taut or un- Wrinkled condition.

Extending upwardly from thecross bars 12 and 14 is apeak pole 68 incorporating in its construction atubular member 70 telescopically receiving awooden rod 72 having a projectingpin 74 on the upper end thereof. Thetubular member 70 is provided with a compression coil spring identical tocoil spring 28 and designated by the same numeral with aplug 30 being disposed therein and connected to thespring 28 in the identical manner. Anadapter 74 is disposed in the lower end of the tubular member 70'and has a generally semi-cylindrical Patented Mar. 15, 1960 '3 lower surface designated by thenumeral 76 forming a saddle for engagement over the upper of the cross bars and specifically for engagement with the central tubular portion: 18 thereof. AscreW- fastenerJS is providedfor securingthe adapter '74 to theplugs 30 thus retaining, the

' pea'la pole 68in position and maintaining the roofportion'of the tent cover imposition. 1

The roofportionofthe tent cover 50 includes four generallytriangular members 80 which are joined by agrommet 82 at the peakthereof for' receiving the projectingpin 74 and anoverlying closure member 84 is provided for thegrommet 82 thus providing a waterproofroof- 80. Fourside walls 86 are provided each of which are generallytrapezoidaland substantially equal 1 inconstruction and provided with one of thewalls 86 being provided with: an opening and closure therefor designated" generally bynumeral 88. Theside walls 86* are interconnected byabottom wall 90 together with:

flapping. The construction also eliminates any center pole. construction thus providing the interior free of obstructions and the device is constructed, of tubular metallic members of lightweight construction such as. aluminumwhich rendersthe device easy to assemble and In actual practice, the entire tent cover disassemble; maybe unrolled and thefranre assembled therewith and ready for occupancy within amatter'of several minutes,

When thin tubular members are employed, a'cap 39 may be employed in the inner end ofmember 26 to asa sure that thespring 28 will enter the end ofmember 26.

It is alsocontemplated that other spring arrangements may be employed by rearranging the elements. As an example, the spring could be" disposed exteriorly of the centralmember with the outer tubular members tele: scoping over the central member.

The-foregoing'is considered asillustrative only of the principles of the invention. Further, since numerous modifications and changes willreadily occur to those skilled in the art, it isnot desired to. limitthe invention to the exact construction and operation shown and described; and accordingly all suitable modifications and equivalents maybe resorted to, falling within the'scope of the invention as claimed.
