Abstract

A free-standing portable, sphere-segment-shaped, shelter is made from basically three types of components; initially straight resilient rods, joining members and, of course, a cover. The rods are bent into arcs within their elastic limit so that two circles are formed and these are separated and a dome provided by other initially straight rods similarly bent elastically; a top joining member in the form of a circular plate can have a central hole to provide ventilation and an outlet for a stovepipe.

The rods are bent into arcs within their [52] U.S.Cl 135/1, elastic limit so that two circles are formed and these are 135/3 separated and a dome provided by other initially straight rods 1] Int.

a 3 2 \Q l r \g 34 5 t 57 5 l6 10 A 5% 3 e 31 PORTABLE SHELTER This invention relates to the field of portable shelters generally and in particular to a shelter which is curvilinear approaching a spherical shape and yet may be completely dismantled with its component parts in the manner of a tent.

As is well known, tents are bonded by edges which are straight, or approximately so, allowing for sag of ropes. Thus, tents generically present large flat areas to the elements. which makes them unsuitable in rough weather; high wind causes the canvas to flap and billow like a sail; much of the floor area is not convenient to use due to central supports or low sidewalls (unless elaborate construction is used) and as the ratio of surface area to enclosed volume is high, they are difficult to heat and are warm-weather or tourist devices.

Many portable shelters of generally curvilinear shape have been proposed. These fall into two main classes which may be graphically (if not quite accurately) described as the umbrella" type and the stressed skin type. The umbrella type has pin joints with the attendant disadvantages that it cannot be completely dismantled; also of course it is expensive and more easily damaged; U.S. Pat. No. 3,039,478 and Canadian Pat. No. 644,662 illustrates this kind of construction. In the stressed skin" type the structure can be dismantled but it relies upon the shape of the cover or sockets in the floor portion of the cover to locate the frame members and hence to bend them to the desired shape; U.S. Pat. No. 2,948,287 and Canadian Pat. No. 681,598 illustrate this type. This classification is approximate and for illustrative purposes only, since, as umbrella covers are stressed, there is obviously overlap between the two types. in one interesting US. Pat. No. 3,269,398 the ground is used to maintain the stability of the framework which would otherwise spring open.

In contrast to these devices, I have found that a free-standing curvilinear three-dimensional frame can be made whose only components comprise straight, resilient elongated members cut to suitable lengths and joint members adapted to receive these straight resilient members. I have also found that a suitable arrangement of these components with correctly chosen lengths results, with a cover, in an enclosed space resembling a major segment of a sphere so as to give adequate headroom above almost the entire floor area. By yet a further step. a large centerpiece at the top of the structure is provided to accommodate and outlet for a stovepipe so that the covered structure may be used for ice fishing.

My invention will be more easily understood by reference to the attached drawing in wherein:

FIG. 1 is a perspective view of an embodiment incorporating all details of the invention with the cover partly removed;

F IG. 2 is a view of an upper junction of four rods;

FIG. 3 is a view of a lower junction of three rods showing that the joint block retains the cover by a pocket.

in FIG. 1 the framework is indicated generally as 10. This structure is independent of the cover 12 in the sense that the framework does not rely for its integrity or stability on the cover but it is complete in itself. The construction of the cover, 12, will therefore be described later.

The framework comprises basically a multiplicity of two simple types of component-resilient members and joint members-it being fully understood that the quantity of each component, their materials and dimensions (and by dimensions 1 means cross-sectional areas, shapes and lengths) below are by way of example only and that changes even quite extensive changes, may be made by those skilled in the art.

Thus, I prefer the resilient members to be all of solid round 3/l6-inch diameter spring steel rod, suitably treated to avoid rust. However, other resilient materials such as glass-reinforced polyester are also suitable for the framework. One series of eight such rods 21 through 28 are formed into a lower circle, generally indicated at 20, with eight hardwood block joining members 14. With 3/ l 6-inch stock spring steel, a convenient length for each rod is 48 inches and thus with eight rods round the periphery. the base diameter is ID feet. The hardwood blocks 14 are 2 inches wide by 3 inches tall by onehalf of l inch thick, the holes being drilled three-sixteenths inch which allowing for the compression of the wood and the moisture absorption outdoors gives a press fit with the rods. I prefer not to drill the holes right through as this gives a positive location for each end of each rod.

A second series of eight resilient rods 31 through 38 are formed into an upper circle generally indicated at 30, again with eight hardwood block joining members 16 each of which has four holes to accommodate tow pairs of rods. I prefer to make each rod 31 through 38 44 inches long when using 3/ l 6- inch spring steel stock to give me a diameter of a little over 9 feetfor reasons which will appear in the next paragraph. incidentally, I prefer to make blocks 14 with only three holes rather than make blocks 14 and 16 interchangeable; the empty hole tends to fill with dirt and the lower surface becomes abraded gradually destroying the initial interchangeability.

The reason I choose these lengths is that l find it convenient to adopt a construction in which the two series of eight resilient rods in the vertical plane (that is the lower series of 41 through 48 and the upper series of 51 through 58) are both 5 feet long. This enables the rods to be distinguished easily; also the maximum diameter of the structure occurs above the base; this latter means that a man of average height can stand upright over a larger portion of the base area. Circle 30 also adds to the stability of the framework.

The lower series of eight S-foot long rods 41 through 48 (44 being hidden by the stovepipe 64 and 46 and 47 by the cover) require no further description but the upper series converge onto and have their ends remote from circle 30 accommodated in top plate 60 which is of %-inch thick plywood 12- inch diameter. When these rods are properly in position in their l-inch deep holes in top plate 60, the height of the top plate about ground level is 6 feet, 9 inches.

The top plate 60, itself serves two purposes; firstly it is a single piece ensuring that all rods are of a convenient length (since otherwise it would be possible to combine diametrically opposite rods such as 51 and 55 to make four unwieldly rods or else have single block-type joints with shorter pieces) and secondly a 4stove diameter hole 62 accommodates stovepipe 64 from the heating stove 66. It will be fully understood that hole 62 is a clearance hole and the stovepipe does not support the top plate 60.

The cover 12 requires little comment; I prefer to stitch eight nylon panels in the shape of truncated ogives together with alternate panels being in contrasting colors, providing a 2-inch double thickness around the base; I also provide eight pockets, 72, as shown in FIG. 3. Hardwood block joints 14 hold the cover on the frame in high winds, the frame being anchored by 10-inch spiral nails. Due to the flexibility of the resilient members 41-48 such a cover will slip over the structure even though the cover base periphery is smaller than the maximum horizontal octagon formed by these rods. Two slide closures (commonly called zip fasteners) 68 and 70, 6 feet long and 2 feet long respectively, are provided for easy access to the interior.

With the above materials and dimensions the tent frame and cover can be accommodated in a bag 6 feet long by about 9 inches in diameter (flattened locally to accommodate top plate 60) and weights about 25 pounds. The number of joints is not critical but if reduced, either the structure becomes too small or the rods become too long and inconvenient for long portages. Incidentally, I prefer to leave the blocks l4, 16 on rods 41-48 when dismantling the shelter as it hastens reassembly and inhibits loss of joint blocks.
