Abstract: A transportable shelter includes a frame, an inner liner, and an outer liner. A plurality of interconnecting members of the frame are connected to create a fixed structural element, at least one end structural element, and a plurality of purlin portions. The purlin portions attach the fixed structural element to a first end structural element. The fixed structural element has a first inner track and a first outer track, and the first end structural element has a second inner track and a second outer track. The inner liner attaches to the first and second inner tracks, and the outer panel attaches to the first and second outer tracks. A dead-air space exists between the inner liner and the outer panel when the frame is assembled and the inner liner and the outer panel are connected to both the fixed structural element and the first end structural element.

Abstract: An exemplary connection fitting for a frame for a transportable shelter includes a female connection fitting configured to be attached to a first interconnecting member of the frame, and a male connection fitting configured to be attached to a second interconnecting member of the frame. The female connection fitting includes a base and a channel extending through the base, and the male connection fitting includes a base and an extension extending from the base. When the female connection fitting is attached to the first interconnecting member and the male connection fitting is attached to the second interconnecting member, the extension of the male connection fitting is inserted into the channel of the female connection fitting to connect the first interconnecting member to the second interconnecting member.

Abstract: A frame for a transportable shelter includes a first base member, a second base member, a plurality of structural members, and a plurality of purlins. Each of the structural members have a first end that is connectable to the first base member, a second that is connectable to the second base member, and at least two interconnecting members that extend between the first end and the second end. A first interconnecting member of a structural member is connectable to a second interconnecting member of the structural member. The plurality of purlins are configured to connect one of the structural members to another structural member.
