4 Claims. (Cl. 135-4) The present invention relates to a foldabletent structure. More particularly, the invention relates to a tent 7 structure having a medially hinged frame, which may be easily folded from an erected position or unfolded to an erected position, for supporting a flexible tent top or cover having sides and a peaked roof.

It is an object of the present invention to provide a foldable tent structure of a kind particularly suited for use by children at play, and which may be easily folded into compact form from the erected position with little diificulty. It is a further object to provide a foldable tent structure which is easily transported or stored in the folded condition and can be erected by one person.

These and other objects of the invention, as well as the advantages thereof, will be apparent in view of the following detailed description taken in conjunction with the attached drawings.

In the drawings:

Fig. l is a perspective View of the foldable tent structure in erected position, the tent top being indicated in chain lines;

Fig. 2 is a fragmentary front elevation of the structure in the position of Fig. 1;

Fig. 3 is atop plan view, taken substantially as indicated on line s 3 of Fig. 2;

Fig. 4 is a bottom plan view, taken substantially as indicated on line 44 of Fig. 2;

Fig. 5 is an enlarged plan section, taken substantially as indicated on line 55 of Fig. 2;

Fig. 6 is an enlarged vertical section, taken substan- 4 tially as indicated on line 66 of Fig. 2;

Fig. 7 is a front view .of the tent structure folded as for storage; and

Fig. 8 is an end View of the folded tent structure.

The tent frame of the invention is indicated generally at 10. The tent top or cover supported by the frame is of a conventional material, such as nylon or canvas woven fabric, and is shown in chain lines in Fig. 1.

The tent frame 10 has an upper portion defined by reotangularly arranged side and end cross members. The side cross members each have a medial hinge or hinge point for folding or unfolding of the tent frame. The outer end of each side member carries a corner member. Roof members for providing a peaked tent top are pivotally connected to each corner member above a side member. Leg members for supporting the frame upper portion are pivotally connected to each corner member below a side member. A yoke member is carried on the outer end of each side member between the hinge and a corner member. Each yoke is slidable on the side member and is connected to a roof and leg member. Means, preferably in the form of cables and pulleys, are provided to simultaneously move each yoke member when the side members are unfolded to extend thereof and leg members in erected position.

. The tent frame 10 includes roof members 12, side cross frame members 14 hinged at the middle for folding,

end cross frame members 16 and leg members 18. The roof, frame and leg members (12, 14, 16 and 18) are preferably formed of aluminum tubing and interconnect at four corner channel members 26. As shown in detail by Figs. 2 and 6, each channel 24 is elongated and has opposed flanges 21 which are relatively wide in relation to the width of the channel Web 22.

The roof members 12 and leg members 18 are secured in similar fashion to the upper and lower ends, respectiveiy, of channel members 20. As best shown in Fig. 6, the connected end of each member 12 and 18 is flattened or pinched together as at 23 for insertion between flanges 21 of the channel member. The flattened ends 23 are secured, as by a double-head rivet 24, within a bushing 25 to permit movement of members 12 and 18 in relation to a channel member.

The outer end of each side cross frame member 14 is also flattened and additionally provided with clevis ears as at 27, enclosing a small cable pulley 28. The member 14 is Secured as by a fiat head rivet 29, also within a bushing 30, to permit rotation of pulley 28.

The end cross frame members 16, which are used for strengthening purposes and extend between channel members Zil, preferably have flattened ends 31 which have been downturned and secured by rivets 31A or welding to inner flanges 21 of opposite channel members 20.

At the corners of the tent frame 10, each roof member 12 and leg member 18 are linked together for simultaneous movement by a yoke 32 slidable along the outer end of each frame member 14. As best shown in Fig. 2, an elongated link 33 extends between a bracket 34 on top of yoke 32 and a fastening pin 35 through a lower leg of a roof member 12. A similar link 36 extends between another bracket 37, on the lower side of yoke 32, and a fastening pin 38 through the upper portion of leg member 18.

Above bracket 37, each yoke 32 has a third bracket 39 to which is attached the end of a cable length 40. At each end of a frame member 14, the cable 40 attached to bracket 39 is trained over and around pulley 28. Both ends of the cable 40 are thus attached to a yoke 32 and tightening thereof Will slide the yokes along frame member 14.

' As shown, the frame member 14 has a hinge point indicated at 45 which permits a folding of the tent frame. On either side of hinge point 45, each frame member 14 has an upward or offset bend indicated at 42. The cable 40 from each pulley 28 preferably passes through the hollow member 14 to emerge through a slot 43 between bend 42 and the hinge point 45.

The cable 40 has sufficient length so that when the tent frame 10 is in the folded condition of Fig. 7, with the yokes 32 having been moved to' their farthest position away from corner members 20, there will be at most only a slight amount of slack in each cable length. This slack may appear in the form of a loop indicated at 4%.

To unfold and erect the tent frame 16, the user would grasp opposite corner members 20 and move them apart.

The frame members 14 will swing away from each other about hinge points 45 and the slots 43 where the cables enter members 14 will move apart so that the cables 40 will be drawn taut. As the cables 43 tighten, the yokes 32 slide toward the corner members 2%. Such movement will extend the leg and roof members and when the frame members 14 are finally moved into alignment,

the leg and roof members will be in the erected condition of Fig. 1. If desired, a stop pin 41 may be inserted through each side in member 14 to limit movement of the yokes 32 toward the corner members 20.

As shown in Figs. 2 and 3, the hinge point 45 is actually a pin 46. Fittedon each frame member 14, inwardly of the cable slot 43, are similar hinge members 47, each 6 having an ear flange 48. The flanges 48 are aligned and fastened together by the pivot pin 46. Below pin 46, each hinge member 47 has a-cooperative lock flange 50 which is used to secure the frarnemembers 14 in the erected position. it is necessary only to grasp the hinge members 47 and disengage the lock flanges 50.

The tent frame constructed as described above is particularly suited for use by children at play,-is light in Weight, may be readily stored and may be'unfolded or folded with minimum effort. The above described construction is preferred; however, changes andmodifications may suggest themselves. Such changes and modifications should be considered within the scope of the appended claims.
