Abstract
A geodesic type shelter having the shape of a semi-ellipsoid of revolution having a large opening in one side and being constructed of elements which are all removably connected together so that it is particularly useful as a portable airplane hangar.
Claims20
A shelter comprising a plurality of structural elements connected together at apecis to form a geodesic dome type structure having the shape of a semi-ellipsoid, and a substantially planar door opening extending substantially in a plane passing through the greatest axis of the semi-elllipsoid, said greatest axis being substantially horizontal to the ground and lying in said plane, said door opening extending upwardly from said axis at an angle outwardly with respect to said structure and passing substantially through a plurality of said apecis to form an overhang at the upper portion of the doorway opening, so that said doorway opening is self-supported without vertical supports and substantially equal to the width of said structure at the bottom and accommodates maximum size objects in relation to the size of the structure.
A shelter comprising:
- a plurality of structural elements connected together to form a geodesic dome type structure;
- said structural elements being elongated tubular pipe members having flat ends with holes through the ends, said flat ends being overlaid with said holes aligned and rigidly connected together by bolt and nut arrangements with the bolts extending through said aligned holes forming apecis of the geodesic structure so that the structure has the shape of a semi-ellipsoid of revolution with the diametral plane thereof being substantially horizontal to the ground;
- a doorway opening in the surface of the structure having a width extending substantially parallel to one of the axes of said ellipsoid and a height less than one-half of the other axis of said ellipsoid;
- a reinforcing truss means extending over said doorway opening comprising elongated reinforcing elements extending from the first apex above ground at each side of said opening slanting upwardly towards the center of the tip of said opening;
- an angle member having a substantially V-shaped cross-section and a shape forming a central portion and two end portions extending at an angle from said central portion, the upper ends of said reinforcing elements being snugly received in the end portions of said V-shaped angle member and the horizontal structural element over the central part of said doorway opening being snugly received in said central portion of said V-shaped angle member;
- angle members each having a V-shaped cross-section and a shape to snugly receive in the angle thereof at its upper end the lower end of one of the reinforcing elements and in a portion adjacent thereto the respective structural element extending upwardly over said opening from the respective apex, and in the lower end the respective structural element extending from the respective apex downwardly at the edge of said opening;
- removable pipe clamps attaching said angle members to said elements;
- reinforcing rod-like members each bent into a plurality of substantially straight sections each extending at an angle with respect to each other and spanning between each respective reinforcing element and the adjacent structural element;
- pipe clamps rigidly attaching the bends and ends of said rod members to the respective structural elements and reinforcing elements;
- anchor means rigidly fixed in the ground and removably attached to said structure;
- and cover means to substantially cover the area within said structure.

A shelter comprising:
- a plurality of structural elements connected together to form a geodesic dome type structure;
- said structural elements being elongated tubular pipe members;
- star-shaped connectors connecting the ends of a plurality of said tubular pipe members together at apecis of said geodesic dome structure, each comprising a plurality of angle members having a V-shaped cross-section rigidly joined together at one end of each angle member, said angle members extending from the central part of the rigid joint radially parallel to the longitudinal axis of said structural elements, said structural elements being nested in said angle members in self-aligning relationship therewith;
- releasable means to fasten said structural elements rigidly to respective angle members, so that the structure has the shape of a semi-ellipsoid of revolution with the diametral plane thereof being substantially horizontal to the ground;
- a doorway opening in the surface of the structure having a width extending substantially parallel to one of the axes of said ellipsoid and a height less than one-half of the other axis of said ellipsoid;
- a reinforcing truss means extending over said doorway opening comprising elongated reinforcing elements extending from the first apex above ground at each side of said opening slanting upwardly towards the center of the tip of said opening;
- an angle member having a substantially V-shaped cross-section and a shape forming a central portion and two end portions extending at an angle from said central portion, the upper ends of said reinforcing elements being snugly received in the end portions of said V-shaped angle member and the horizontal structural element over the central part of said doorway opening being snugly received in said central portion of said V-shaped angle member;
- angle members each having a V-shaped cross-section and a shape to snugly receive in the angle thereof at its upper end the lower end of one of the reinforcing elements and in a portion adjacent thereto the respective structural element extending upwardly over said opening from the respective apex, and in the lower end the respective structural element extending from the respective apex downwardly at the edge of said opening;
- removable pipe clamps attaching said angle members to said elements;
- reinforcing rod-like members each bent into a plurality of substantially straight sections each extending at an angle with respect to each other and spacing between each respective reinforcing element and the adjacent structural element;
- pipe clamps rigidly attaching the bends and ends of said rod members to the respective structural elements and reinforcing elements;
- anchor means rigidly fixed in the ground and removably attached to said structure;
- and cover means to substantially cover the area within said structure.
