4 Claims. (Cl. 135- 3) This invention relates to portable shelters, such as tents, screened or enclosed cribs, cabanas, portable screen porches and the like.

An object of the invention is to provide a novel and improved portable shelter construction of the above class having unique features by which it may be very quickly set up and dismantled.

Another object of the invention is to provide an improved shelter construction as above characterized, which may be packed into very little space when dismantled.

A still further object of the invention is to provide an improved shelter construction of the above type and which is characterized by a relatively rigid supporting frame portion and a flexible or non-supporting screen or wall portion, wherein the frame portion may be first readily set up in its entirety and thereafter the screen or wall portion quickly and easily attached to the frame portion, the reverse operation being carried out when dismantling the shelter.

Yet another object of the invention is to provide an improved frame construction for a portable shelter, which is strong and sturdy and yet permits of quick and easy assembly or setting up of the frame, and also dismantling thereof.

A feature of the invention resides in the provision of an improved frame construction for a portable shelter as above characterized, which by suitable modification of i the length of certain of the components, will enable frames of different configurations and shapes, and functions to be readily obtained.

A still further object of the invention is to provide improved means for attaching the screen or wall portions 'ofa shelter to the rigid frame portions thereof.

Another feature of the invention resides in the provision of improved attaching means between the screen or wall portion and the frame structure, which permits of easy and rapid assembly and disassembly, even under adverse and severe conditionsof weather.

Other features and advantages will hereinafter appear.

In the drawings accompanying this specification, similar characters of reference indicate corresponding. parts wherever possible in the several views; in which:

Figure 1 is a perspective view of a portable shelter in the form of a tent made in accordance with theinvention;

Fig. 2 is an exploded perspective view of an upper juncture of the frame structure of the tent shown in Fig. 1;

Fig. 3 is a fragmentary sectional view taken on line 3-3 of Fig. 1;

Fig. 4 is a fragmentary perspective view of a lower corner portion of the tent shown in Fig. 1;

Fig. 5 is a perspective view of a portable shelter in the form of a tent, illustrating another form of the invention;

Fig. 6 is a fragmentary perspective view of an upper juncture portion of the frame structure of the tent shown in F ice Fig. 7 is a front elevational view of a hook member as provided by the invention, for the purpose of attaching the flexible screen or Wall structure of a shelter to the rigid frame structure thereof.

Referring to Figs. l-4 the improved portable shelter as provided by the invention comprises essentially a relatively rigid frame structure 20 to which there is releasably attached a flexible wall or covering structure 21.

The frame structure 20 comprises a plurality of elongate, substantially rigid and yet slightly flexible, upstanding frame members 23, here shown as four in number. The frame structure also comprises a substantially horizontal, elongate, rigid yet somewhat flexible frame member 25. As shown in Fig. 2, the frame members 23 and 25 have tubular or socketlike adjoining terminal portions, and this may be effected by making the members of tubular stock as shown, or by making the members of solid rod or bar stock and providing sleeves on the terminal portions, as will be readily understood.

In accordance with the present invention I provide a novel and improved junction or connector means for rigidly joining the frame members 23 and 25. This junction means comprises a multi-pronged connector member 26 which may have prongs 27, 28 and 29 receivable in the socketed ends or terminal portions of the frame members 23 and 25. The connector member 26 may be formed in any suitable manner, as for example by bending a shortsec'tion or length of solid bar stock into a V-shape and welding another .short section of bar stock to the yoke of the. V. I i v In accordance with theinvention, in conjunction with the novel junction means illustrated in Fig. 2, I provide a tension means for effecting a flexing of the horizontal frame member 25, thereby to cause all of the frame members 23, 25 of the structure to be placed under appreciable stress and to be securely held together in assembled relation with each other. As shown in Fig. 1, this tensioning means may comprise a tie cord 31 at its extremities joined to the upper corners of the tent, said tie cord having an elastic link 32 by which it may be connected under tension to effect the fiexure of the member 25 as illustrated. It will be understood that the frame structure as above set forth is first assembled by inserting the prongs 27, 28 and 29 of the connector members 26 in the proper terminal portions of the frame members, and thereafter inserting the lower ends of said rods in the corner sockets Prior to such stressing or even prior to assembly of the frame members, the lower terminal portions of the members 23 may be disposed in sockets 35 by which they are held in fixed relative positions. Such sockets, for example, may be provided on the. lower portions of the covering or flexible wall structure 21 of the shelter, and may advantageously be in the form of fabric sleeves.

Further, in accordance with the invention, Iprovid'e novel andimproved means by which the fiexiiblewall structure 21 is secured .to the frame structure 20. Referring to Figs. 5 and 7, the wall structure 21 may have a plurality of hook members 37, each of said hook members having a curved bill portion 38 adapted to extend around the frame member 23, and having a base portion 39 provided with a relatively long slot 40 by which the hook may be secured to the corner seam of the cover structure, either with a suitable piece of fabric or webhing or by suitable stitches or other fastening means. By the provision of the books 37 the wall structure 21 may be easily and quickly attached to or detached from the frame structure 20 of the tent.

By this invention I also provide another novel and advantageous' means by which the wall structure 21 may be secured quickly and easily to the frame structure 20, and as quickly and easily detached therefrom. Referring again to Fig. 1, there is shown an elongate sleeve 43 secured to a front corner seam of the cover structure 21, said sleeve having an elongate, longitudinal cut and being provided with cooperable zipper means by which the sleeve may be separated into two distinct spread-apart portions for introducing or removing an upstanding frame member 23, and by which the sleeve may be secured around such frame member to attach the wall structure 21 thereto. I prefer to so arrange the zipper means 44 on the sleeve 43 that the zipper is open when the slider thereof is disposed at the lower portion of the tent, and vice versa.

Additionally, in accordance with the invention, I provide yet another improved and advantageous means for attaching the wall structure 21 to the frame structure 20. Referring now to Figs. 1 and 3, the wall structure 21 may be provided along its corner seams with pairs of flexible tabs 46, 47 formed of webbing or other suitable material, said tabs having apertures and cooperable hasp means 48 in said apertures and adapted to receive a single pull cord 49 by which the hasp means may be locked in closed positions. The tabs 46, 47 are adapted to extend around the frame member 23 when the hasp means thereof are closed, thereby to secure the wall structure 21 to the frame member. By merely removing the pull cord 49 from the hasps, which may be done by a quick and simple operation, the wall structure 21 may be quickly freed from the frame structure 20, as will be readily understood.

By the present invention the tent construction shown in Fig. 1 may be provided with a rigid floor member 52 which is water-impervious and which may carry the sockets 35, and the floor member 52 may have attached to it side walls 53 which are also water-impervious, thereby to enable the tent to float and be buoyant if it should be placed upon a surface of water.

In place of the hooks 37 shown in Fig. 5, loops 55 of fabric or webbing may be utilized, said loops being secured to the corner seams of the wall structure 21.

A portable shelter in the form of a tent illustrating another form of the invention is shown in Figs. and 6. In these figures there are illustrated upstanding frame members 58 and a substantially horizontal frame member 59, all in the form of solid rods, said members being provided adjacent their terminal portions with fixed collars 60 and 61 acting as stops for a junction means. As seen in Fig. 6, the junction means comprises a short length of tubing 62 having transverse openings in its walls, con stituting sockets for receiving the terminal portions of the frame members 58, 59. While the junction member 62 is shown as a short length of tubing, it should be understood that it may be made of solid stock and of any suitable material, such as metal, reinforced plastic, wood, etc. I provide a tension means in the form of a tie cord 64 to cause fiexure of the frame member 59 and stressing of all of the frame members, the tie cord 64 having an adjustment such as an elastic link 65 and being secured at its extremities to the terminal portions of the horizontal frame member 59.

The shelter of Fig. 5 may have a flexible wall structure 67 provided with hooks 37 as described above, by which 4 it may be quickly and easily attached to the frame structure and detached therefrom, two hooks 37 at the front and rear peaks being received in openings 62a of the junctions 62.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.

I claim:
