A portable shelter is provided for sheltering materials or human occupants at a remote location. The shelter includes, among other things, a flexible cover and a supporting frame. In operation, hinged members that are part of the frame are used to support a first portion and then a second portion of the shelter. Before the frame is raised up, the people who are constructing it can easily reach the top parts of the shelter without a stepladder or the like. By avoiding the need for a stepladder, the overall size and weight of the assembled components that have to be transported to the remote location can be reduced, and the shelter can be constructed more quickly and easily. Hinges, purlin connections, and corner closure systems for the shelter are also disclosed.

1. A portable shelter for sheltering materials or human occupants at a remote location, said shelter comprising: a flexible cover; anda frame for supporting the flexible cover, the frame having a length in a first direction and a width in a second direction, the length being greater than the width, and the second direction being perpendicular to the first direction; andwherein the frame includes first and second hinged members for supporting a first side and then a second side of the shelter; andwherein the frame includes arches extending in the second direction, wherein one of the arches includes the first and second hinged members, and wherein each one of the arches has an arched configuration, and wherein each one of the first and second hinged members has an arcuate shape to conform to the arched configuration, and wherein the frame includes braces located between the arches; andsnap-in purlin connectors for releasably connecting the braces to the arches; andwherein the frame includes third and fourth members for supporting the portable shelter in a partially-constructed configuration, and-wherein the first and second members are hingedly connected to the third and fourth members, respectively, and wherein the portable shelter has a side wall and an end wall, the side wall extends in the first direction, and the end wall extends in the second direction, and wherein the flexible cover has a closeable corner structure, between the side wall and the end wall of the portable shelter, for providing access into the portable shelter during an intermediate stage of construction; andwherein the first member is movable relative to the third member through a plane that is essentially perpendicular to a line that extends from the hinged connection between the first and third members toward a floor of the portable shelter, and wherein the third member has the arcuate shape. 2. A portable shelter for sheltering materials or human occupants at a remote location, said shelter comprising: a flexible cover; anda frame for supporting the flexible cover, the frame having a length in a first direction and a width in a second direction, the length being greater than the width, and the second direction being perpendicular to the first direction; andwherein the frame includes first and second hinged members for supporting a first side and then a second side of the shelter; andwherein the frame includes arches extending in the second direction, wherein one of the arches includes the first and second hinged members, and wherein each one of the arches has an arched configuration, and wherein each one of the first and second hinged members has an arcuate shape to conform to the arched configuration, and wherein the frame includes braces located between the arches; andsnap-in purlin connectors for releasably connecting the braces to the arches;wherein said shelter includes: plural arch assemblies each including five arch members hinged and folded together so that the arch assemblies are not substantially longer than any one of the arch members; hinges located between the arch members for yieldably retaining the arch assemblies in partially-extended configurations or fully-extended configurations; and braces for connecting the arch assemblies together in an essentially parallel arrangement, none of the braces being substantially longer than any of the arch members; and wherein the second, the third, and the fourth arch members are configured to be unfolded from the respective arch assemblies to support a partially-constructed configuration of the portable shelter resting on the hinges between the first arch member and the second arch member and the hinges between the fourth arch member and the fifth arch member, and wherein the first and fifth arch members are configured to be unfolded from the respective arch assemblies to support a fully-constructed configuration of the portable shelter resting on an end of the first arch member and an end of the fifth arch member; andwherein the arch assemblies are arranged to be secured in an arcuately aligned configuration to support the flexible cover;wherein each arch member has a radius R and an arcuate length of about W/5, where R is at least nine feet and approximately equal to the headroom of the portable shelter when fully constructed, and where W is the arcuate length of the respective arch assembly when the portable shelter is fully constructed. 3. The shelter of claim 2, further comprising a floor connected to the arch assemblies for tensioning the flexible cover. 4. The shelter of claim 3, wherein the flexible cover includes a door for allowing a person to walk into and out of the structure. 5. The shelter of claim 4, further comprising a container for transporting the arch assemblies, the braces, and the flexible cover to a remote location. 6. The shelter of claim 2, wherein the hinges are snap-locking hinges. 7. The shelter of claim 2, wherein the flexible cover has a closeable corner structure, between a side wall and an end wall of the portable shelter, for providing access into the portable shelter during an intermediate stage of construction. 8. The shelter of claim 7, wherein the closeable corner structure includes a zipper and/or hook and loop fasteners.
