ABSTRACT:
A tent comprising a fabric shell supported by a skeleton frame having at least two criss-crossing ribs. The tent has first and second criss-crossing sleeves for receiving the ribs. Each sleeve defines a closed, uninterrupted passage having at least one open end for the continuous, uninterrupted insertion of a respective rib into the sleeve. At least one of the sleeves is positioned below one of the other sleeves at the location where the sleeves criss-cross so that the passages defined by the sleeves do not intersect. The improvement comprises the sleeves being secured in fixed position relative to one another generally at the location where their respective ribs criss-cross thereby to stabilize the sleeves relative to one another and to the shell.
