Abstract
A frame for a shelter, a shelter and structural members used to make the frame are provided. The structural members are cruciform in cross section and have swivel means which are used to connect structural members to other structural members to construct the frame of the invention. The swivel means used can be of several different types. The swivel means on the structural members make it possible to fold a frame constructed from the structural members into a small package. The structural members can be uniformly constructed, their function in the frame depending on where they are used in the frame and the particular swivel means used in their attachment. A covering is used to cover the frame and the frame and the covering together represent the shelter of the invention.
