United States Patent() COLLAPSIBLE TENT FRAMEWORK John G. Call, Pikeville, Ky., assignor to The Telatent Company, Inc., Pikeville, Ky., a corporation of Kentucky My invention has to do with tent framework and relates particularly to the provision of a collapsible and adjustable tent framework which may be collapsed and folded into compact bundles or units which are adapted to be associated together to form compact carrying cases by means of which the structure may be conveniently transported from place to place.

In my copending application Serial No. 194,452, filed November 7, 1950 and entitled Tent Framework, now Patent No. 2,723,673, dated November l5, 1955, i have taught a collapsible and adjustable tent framework made up of a plurality of corner assemblies or units which when set up and coupled together form the supporting structure or framework over which the canvas tent cover is placed. Each of the corner post units includes a generally triangular box-like frame formed of right angle stock.

In an assembled tent structure formed from the units just described, the box-like frame members do not constitute parts of the tent framework as such. Consequently,

` I have now developed a tent framework in which the separate box-like frames are eliminated and the structural parts of the framework, such as the members which dene the eaves of the tent, themselves form the parts ofl the box-like frame when collapsed to the elimination of the channel bars referred to in describing the structures of my copending application. Thus I now provide corner units which comprise a lesser number of parts and hence are of less bulk and weight.

It is a principal object of my invention to provide a novel tent framework of light weight construction which may be collapsed and folded into a plurality of units which when joined together form of themselves a handy container or case for the transportation of the entire structure to a desired tent site.

Another object of my invention is the provision of a framework for supporting a tent cover, formed of angle stock and including means for both lateral and vertical expansion of the frame member from compact, collapsed bundles into a complete and rigid tent structure. i

Yet another object of my invention is the provision of a collapsible tent structure the parts of which may be adjusted during erection to provide tent structures of varying sizes depending upon the needs of the user.

Still another object of my invention is the provision of a tent structure formed from a plurality of collapsible units, the frame members of the units when erected being adapted to be readily connected together to provide the completed framework. The tent structure of the instant invention is such that it may be completely'r assembled and erected by one person without tools or special equipment, the structure having no loose pins, loose pieces, and nothing to lose or misplace, Vit being necessary only to couple together the frame members of the several' corner units.

These and other objects of my invention which will appear hereinafter or will be apparent to one skilled in the art upon reading these specifications, I attain by those structures and those arrangements of parts of which II shall now describe certain exemplary embodiments. t

In the embodiment of my invention illustrated in Figures 1-14, my improved tent framework is readily erected by setting up and coupling together four corner assemblies or units indicated as A, B, C and D in Figure 1. Units A and C are identical excepting as will be pointed tion.

respects. Furthermore, units A and C, and B and D are basically the same excepting tha-t units A and C carry a three-way joint or fitting at the end of their rafter members with ridge-pole forming members connected to the joints.

The units each comprise frame members formed of right angle stock telescopically fitted together and pivoted at certain joints so that each unit is collapsible and foldable into a compact bundle, for purpose of transporta- While the telescoping members illustrated are formed of angle stock, it will be readily apparent that tubular telescoping members, such as those disclosed in my said copending application, may be employed to good advantage, it being my purpose here to illustrate how angle stock may be successfully utilized in telescoping relationship to provide a collapsible tent framework.

Referring now to Figures l and 2, each of the four corner assemblies or units includes atriangular base plate 1. 'Each of theseplates 1 has fixed thereto, as will be later described in detail, other appurtenances in- Patented Nov. 27, 1956,.

cluding a vertically disposed telescoping corner post orpole 2. 'Pivotally attached by a suitable `j'oint 'to 'the upper end of each of the four corner posts are threeother telescoping members 3, 4 and 5. Two of thesemembers 3 and 4 are mounted to be horizontally disposed at right angles to each other while thethird member 5 is arranged to be inclined with respect to the horizontal members. In addition, the corner units A and C have joints orfittings 6 on the free ends of theinclined members 5, the joints having ridge-pole forming members 7 extending therefrom at right angles to themembers 5 and parallel to themembers 3.

As will now be apparent, the joining together of the four units A, B, C and D, results in the tent `frame structure of Figure l. Theinclined members 5 constitute the rafters of the roof structure; thehorizontal members 3 define what may be termed the eaves of the roof; the horizontal members 4 serve as joists to rigidify the structure and to connect together the corner units A and B, an C and D; themembers 7, as already indicated, dene the ridge-pole of the structure; and the tour corner posts serve to support the entire structure.

As will be readily understood, the roof and side walls of the tent structure will be provided with a cover of canvas or the like (not shown) which cover is formed to it over the framework and in itself forms no part of the present invention.

Referring now to Figures 7 through l2, thecorner posts 2 of units A and C, which units include thejoints 6 andridge forming members 7, each comprises alower section 8, iixed to thebase plate 1, and anupper section 9 slidably litted Within the lower section. As can be clearly seen in Figure l2, theupper section 9 is slidably fitted within thelower section 8 by means of the U-shaped channel members 10 secured to thelower section 8 in the manner illustrated.

Thechannel members 10 are of a length suicient to prevent undesirable side-wise movement of the telescoping members relative to each other and yet they do not inhibit axial movement of the members. While I have illustrated a pair of channel members positioned near the upper end of thelower section 8, it will be understood that additional pairs of channel members may be employed, if so desired, or the proportionate lengths of a single pair of channel members increased or decreased for posts of various sizes.

As will be seen in Figures 7, 8 and l0, theupper section 9 of the corner post includes a spring pressedlatch pin 11, which pin, as the two sections are drawn to their extended relation, snaps into one of theperforations 12 in thelower section 8 to lock and retain the sections in various extended positions, thereby enabling the user to vary the overall height of the corner posts as determined by the number and spacing of theperforations 12 in the lower section S.

Theupper section 9 carries near its lower end astop 13 in the form of a pin which will engage beneath the lowermost end of one of thechannel members 10 when the sections i; and 9 are fully extended. By means of this arrangement, the sections cannot be extended beyond their operative limits to become accidentally disengaged.

Thechannel members 10, thelatch pin 11, thelocking perforations 12, and thestop pin 13, as described above, comprise a typical sliding and locking arrangement which may be employed with all other pairs of telescoping sections throughout the structure, and the others will not be described in detail herein.

The upper end ot thecorner post section 9 has fixed thereto a joint or fitting 14 having angu'larly disposedarms 15, i6 and 17 to which are pivoted themembers 3, 4 and 5, respectively. Thearms 15 and 16 are substantially horizontally disposed and parallel adjacent side edges of thebase plate 1, being at right angles to each other. Thearm 17 is parallel to but inwardly disposed with respect to thearm 16 and inclined upwardly at sub- Statltially'the 'angle 'f the r'ffeS fith'e e'refed S'fl'llctre. If desired, thearm 17 may be secured to thearm 15 in the manner illustrated in Figures 9 and 10, the purpose being to space thearm 17 from the arm 16 a distance su'icient to permit clearance of themembers 4 and 5 when the corner unit is collapsed.

Thebase plate 1 of each of the corner post units has vertically disposedside members 18 and 19 corresponding in Vlength and position to the -arms 15 and 16. Theside members 1S and 19 of the base plates have latch pins 29 and 2l respectively, adapted to receive the L-shapednotches 22 and 23 on the free ends of themembers 3 and 4 respectively. The latch pins andthe notches serve to detachably secure the ends of themembers 3 and 4 to the base plate, and thus, when collapsed, dene the generally triangular frame which forms a part of a carrying case.

The manner in which the corner unit A collapses is illustrated in dotted lines in Figure 2, the numbered arrows indicating the successive steps involved. Thus, theridge member 7 is rst pivoted in the manner indicated by the arrow i so that it lies parallel to and adjacent the `member 5. It will be understood that if the members comprise telescoping parts, the parts will be rst telescoped together. Next, therafter member 5 is pivoted downwardly about thearm 17 in the manner illustrated by arrow II. This movement carries thejoint 6 and themember 7 along with themember 5. Next the member 4 is pivoted about thearm 16, as indicated by arrow III, and themember 3 is then pivoted about thearm 15 as indicated by the arrow IV.

From what has been described thus far, it will be apparent that the arrangement of the corner post units is such that the various frame members of each unit collapse into a compact bundle, the collapsed horizontal framework members and the corner posts together with the base defining a substantially triangularly shaped frame which may be joined with another such frame to form a square, box-like carrying case which may be readily transported from place to place. Two of the triangular frames so formed may be fitted together in the manner diagrammatically illustrated in Figure 9 for carrying purposes. As seen therein, a pair of the corner post units, such as the units A and B, are brought together in opposed relation and interconnected by means of the inturned anges of theframe members 3 and 4. It will be understood that the corner post units C and D will be interconnected in like manner; and one of the units of each pair will be slightly larger than the other to permit them to be interlocked in the manner illustrated.

In Figures 13 and 14 I have illustrated a second corner unit which is either the unit B or D, since these are identical in all respects. Since the units B and D are identical in their principal parts with units A and C excepting they do not include thejoints 6 and ridge-pole members 7, like parts have been given like reference numerals to simplify the description.

Reference is now made to Figures 3 and 4 for details of the manner in which the contacting members of units A and D are connected together in the erected structure, it being understood that units B and C will be connected together in like manner. The connections between the members 4 ofthe uni-ts A 'and B, and C and D will also be made in the same manner, as will be readiiy apparent from the drawings. In Figure 1 it will be noted that thetelescoping members 3 of units A and D each comprise an `inner section l24 and anouter section 25. Theouter section 25 of unit A carries acoupling member 26 riveted or otherwise secured thereto, thecoupling member 26 also being formed of angle stock. As already indicated, one end of the coupling is secured to themember 25 of unit A With the opposite end extending freely therebeyond and adapted to receive the free end ofmember 25 of corner unitD. Channel members 27 and 2S are provided on thecoupling 26 to receive the end ofmember 25 of unit i).Member 25 of unit D carries a spring pin 29 which, when themember 25 of unit D engages the coupling and abuts against the end ofmember 25 of unit A, passes through opening 38 in the :coupling to secure the two members 2S together.

The same type of coupling connects the members 4 of the various corner units, the coupling being carried on the members 4 of the units B and D and Ithe spring pins on the members 4 of the units A C.

In Figure 5 i have illustrated the joint 6 and the manner in which themember 5 of unit B or D yis connected to it. The joint 6 has anarm 31 which is adapted to fit beneath thechannel members 32 and 33 secured tomember 5 of corner unit E or D. A spring pin carried by thearm 31 engages in theopening 35 in themember 5 to lock the parts together. As will be seen in Figure 6, the arm 3i may be lol-shaped and thespring pin 34 fitted into the U and controlled by means of acompression spring 36.

It will now be apparent that the corner units A and C are substantially identical excepting the ridge-pole member 7 of unit A carries a coupling, such as the coupling illustrated in Figure 4, whereas the ridge-pole member of unit C does not have a coupling but rather has a spring pin for engaging the opening the coupling to lock the two ridge-pole members together.

ln Figures through 18 l have illustrated a modification of my invention particularly adapted for use as the framework of a pup tent. This modification is much simplified but nevertheless embodies the principie of collapsing the frame members into compact bundles, the members themselves defining size and Shape or" the bundle.

Referring to Figure 15, the pup tent framework comprises like units X and Y, each unit comprisingframe members 37, 38 and 39. As will be most clearly seen in Figures 16 and 17, themember 37 is pivoted at 4d to themember 39 and themember 38 is pivoted to themember 39 at 41. Thus, when the unit X, for example, is collapsed, themember 37 will collapse along themember 39 in the manner illustrated by the arrow V in Figure 15. Themember 38 will collapse in a like manner on the opposite side ofmember 39 thus forming a collapsed unit which is square in cross section. Unit Y will of course collapse in the same manner.

The units X and Y may be conveniently joined together by means of the arrangement illustrated in Figure 18 wherein themember 39 of unit X has a tongue 42 eX- tending therefrom and themember 39 of unit Y has a complementary tongue 43 extending therefrom. The tongues are adapted to lie at right angles to each other and hence underlie adjacent sides of the angle bars 39. Spring pressedpins 44 and 45 are provided for engagement with theopenings 46 and 47 to lock the parts together. Of course, if desired the coupling and channel bars illustrated in Figure 4 may be employed, or conversely the attachment means just described may be employed with the embodiment illustrated in Figures 1 to 14.

It will be understood that modifications may be made in my invention without departing from the spirit of it. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
