发明名称 Rotating bracket assembly for collapsible and permanent building-frame construction
摘要 A rotating bracket assembly comprises first and second members, each of which defines a channel having opposing sides coupled to a common base. The first member is nested within the second member with adjacent opposing sides being hingedly coupled to one another so that the first member can freely rotate 360° relative to the second member to achieve a plurality of rotational positions. A first plurality of holes formed in the opposing sides of the first member at least partially align with a second plurality of holes formed in the opposing sides of the second member for each of the rotational positions.
