Portable shelters

A shelter comprising:

• a frame structure comprising a first support arch, a second support arch, and a third support arch, wherein the first support arch comprises two arms and a transverse portion connecting the arms, and wherein the third support arch is attached to each arm of the first support arch at a corresponding attachment location along each arm of the first support arch;
• a flexible shell configured to be supported on the frame structure;
• a plurality of fasteners, and
• a base for supporting the frame structure;
• wherein:
• the first support arch is pivotably attached to the base via a hinge;
• the second support arch is pivotably attached to the base via the hinge;
• the hinge comprises a plate element extending away from a side of the base;
• the plate element comprises a plurality of parallel elongated slots extending entirely through the plate element along a transverse direction relative to an edge of the base;
• the plate element is positioned between the two arms of the first support arch;
• each of the first support arch and the second support arch is attached to the plate element via a corresponding fastener of the plurality of fasteners;
• the fasteners are fixed in place relative to the plate element in a triangular pattern;
• the first support arch comprises a telescoping joint configured to selectively extend the first support arch away from the base in an extended configuration or toward the base in a retracted configuration;
• when the first support arch is in the retracted configuration, each attachment location is positioned a first distance away from the hinge;
• and
• when the first support arch is in the extended configuration, each attachment location is positioned a second distance away from the hinge that is greater than the first distance.

A shelter comprising a frame structure, the frame structure being configurable between a stowed configuration and a deployed configuration, the frame structure comprising:

• a first support arch pivotably attached to a container via a pair of plate elements connected to the container, wherein the first support arch comprises two arms and a transverse portion extending between the arms, and wherein each arm includes a telescoping joint for extending or retracting the arms;
• a second support arch attached to the arms;
• and
• a fastener extending through a first plate element of the pair of plate elements and through a first arm of the two arms;
• wherein:
• for each of the plate elements, the plate element comprises a plurality of parallel elongated slots extending entirely through the plate element along a transverse direction relative to an edge of the container;
• the telescoping joint moves the second support arch toward and away from the plate elements;
• the plate elements are positioned between the arms;
• and
• the fastener is fixed in place relative to the first plate element.
