<p>A shelter frame having at least two poles (1) connected by a linkage assembly (100) having first and second scissors-type linkages and a linking device (110, 112). The scissors-type linkages include first structural members (102, 104) pivotally coupled to respective second structural members (106, 108) and to one another. The linking device (110, 112) pivotally secure a predetermined portion of the second structural member (106) in the first scissors-type linkage to the second scissors-type linkage at a point on the second scissors-type linkage vertically spaced from the predetermined portion of the second structural member (106) in the first scissors-type linkage and to also pivotally secure a predetermined portion of the second structural member (108) in the second scissors-type linkage to the first scissors-type linkage at a point on the first scissors-type linkage vertically spaced from the predetermined portion of the second structural member (108) in the second scissors-type linkage.</p> |
