Abstract
Abstract A tent-like structure, hereafter called a pavilion with a series of curved arches and a panel of flexible membranous material attached to each pair of arches and tensioned in both directions with the panels concavely curved in the direction of the spacing of the arches as well as convexly curved in the other direction to minimize flutter and vibration and to enhance its load-carrying capacity. The panels are attached to the arches by inserting beads on their edges into tunnels in the arches so that the panels may slide lengthwise of the arches to tension them lengthwise. The arches are mounted on rails to swing from recumbent to upright positions and to slide toward each other, to to facilitate assembly of (attach) the panels to the arches, and away from each other, to tension the panels transversely. To move the arches apart and tension the panels transversely, extensible struts, such as toggles or jack-screws, are provided between (each pair of) the arches. Alternate arches may be made larger or smaller than the other arches to enable inside struts to be used without interference with the panels. End closures, of the same general construction as the body of the shelter which may close the ends of the shelter or nest with the body of the shelter to open the ends, may also be provided. The concave transverse curvature may be imparted to the panels in the manner disclosed in the applicant's application, Ser. No. 93293, filed Nov. 17, 1971, or by preforming the panels with such curvature.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
In the construction of a vaulted membrane shelter comprised of at least two substantially vertical arches with curved bights mounted on the ground or other base face to face but spaced apart and fixed in space to form a vaulted framework; a roof membrane, extending between, and operatively attached to said arches and said base that is tensioned longitudinally and transversely with an inward concave curvature of at least 5 percent of the distance between said arches; the method of erection that includes the following steps: a. assembling said arches on said base b. raising said arches to an upright position and fixing them in space in substantially their erected positions c. installing said roof membrane by operatively attaching it to said arches in sections or as a whole d. pulling and sliding said roof membrane along said arches downward toward said base e. tensioning said membrane downward between said arches and securing it: 1. directly to said base; 2. indirectly to said base by at least one tension ring with its ends attached to: a. said base; b. the lower portion of said adjacent arches.
Claim 2
Dependent Claim
186 words
In the construction of a vaulted membrane shelter comprised of at least two substantially vertical arches with curved bights mounted on the ground or other base face to face but spaced apart and fixed in space to form a vaulted framework; a roof membrane, extending between, and operatively attached to said arches and said base that is tensioned longitudinally and transversely with an inward concave curvature of at least 5 percent of the distance between said arches; the method of erection that includes the following steps: a. assembling said arches on said base b. raising said arches to an upright position and fixing them in space in substantially their erected positions c. installing said roof membrane by operatively attaching it to said arches in sections or as a whole d. pulling and sliding said roof membrane along said arches downward toward said base e. tensioning said membrane downward between said arches and securing it: 1. directly to said base; 2. indirectly to said base by at least one tension ring with its ends attached to: a. said base; b. the lower portion of said adjacent arches.
Claim 3
Dependent Claim
27 words
The erection method described in claim 1 wherein the fixing of the arches in space includes at least one strut extending between and attached to said arches.
Claim 4
Dependent Claim
28 words
The erection method described in claim 1 wherein the fixing of the arches in space includes a tension member that extends from each end arch to said base.
Claim 5
Dependent Claim
30 words
The erection method described in claim 1 wherein said arches are attached to said base for horizontal adjustable movement after being raised to their erected position for spacing and alignment.
Claim 6
Dependent Claim
80 words
The method described in claim 1 wherein said vertical arches are fixed in their vertical positions by erecting at least one semi-arch acting between at least one terminal vertical arch and the base in step (b) by attaching one of its ends to the terminal vertical arch near its apex and its opposite end attached to the ground or base to form a unit frame with said vertical arches and to also support a flexible membrane closure for the shelter.
Claim 7
Dependent Claim
96 words
The method described in claim 5 wherein at least one flexible membrane end closure is installed along with said roof membrane, as a unit of, or as a segment of, said roof membrane, is operatively attached to said terminal vertical arch and said vertical semi-arch, and is tensioned with an inward curvature between them, when said roof membrane is tensioned and is secured to the base by at least one tension ring embodied in the lower portion of said membrane with its ends attached to: (a) the lower portion of said semi-arches; (b) to the base.
Claim 8
Dependent Claim
159 words
In the construction of a vaulted membrane shelter comprised of at least two substantially vertical arches with curved bights mounted on the ground or other base face to face but spaced apart and fixed in space to form a vaulted framework; a roof membrane, extending between, and operatively attached to said arches and said base that is tensioned longitudinally and transversely with an inward concave curvature of at least 5 percent of the distance between said arches; the method of erection that includes the following steps: a. disposing said arches on said base with their corresponding ends aligned and their crowns similarly oriented in substantially recumbent positions but spaced apart to facilitate attachment of said membrane b. operatively attaching said roof membrane to at least a portion of the crown of said arches c. raising the arches, with the membrane attached, to substantially their erected positions and fixing them in space d. tensioning said membrane downward and securing it:
Claim 9
Dependent Claim
