the side trusses 16 attach to the upper coupling 44 and lower coupling 46 which are attached to the post 12 such that a angle 74 of approximately 45 degrees is formed between the side trusses 16 and the with the intermediary sides 70 of the posts 12 by way of comparison as shown in fig1 prior art collapsible shelter frames 80 employ posts 12 that are positioned such that the sides of the posts 12 are parallel to the sides of the shelter envelope 82 likewise the peak trusses 18 of the prior art shelter frames 80 attach to the posts 12 at a corner of the posts 12 and form an angle of approximately 45 degrees with the sides of the post 12 the orientation of the posts 12 relative to the envelope 84 and other components of the frame 10 of the shelter of the present invention provides distinct advantages over the prior art shelters for example the rotation of the posts of the frame 10 of the present invention results in a space occurring between the exterior side 68 of the post 12 and the corner of the shelter envelope when the frame 10 is in the collapsed state within this space the eave strut 32 and strut support 38 of the eave assembly 30 are disposed when the frame 10 is in the collapsed state as a result a collapsible shelter having an eave feature according to the present invention can be collapsed into substantially the same envelope as that of a shelter that does not provide an eave further advantages.
