Claim Text:
1. A pet barrier comprising: a housing containing a barrier, the barrier having a first end attached to a holding structure, the holding structure rotating with respect to the housing, the barrier being furled around the holding structure, and the barrier having a second end exposed from the housing, the second end of the barrier extended from the housing and including a first elongated bar hook attached to the second end of the barrier having at least a hooking portion on a side of the elongated bar hook opposite the side that this attached to the barrier; a tensioning mechanism including a torsion spring assembly operably associated with the holding structure; an adjustment structure for adjusting the tension of the spring assembly by rotational action which adjusts the torsion spring forces that act upon the associated holding structure and thereby adjusting tension in the barrier as it is extended from the holding structure; and a brake that locks the adjustment structure to a set tension of the spring assembly by engagement with a portion of the housing and/or a portion fixed with respect to the housing; wherein constant retraction forces act upon the barrier as it is unfurled from around the holding structure, wherein the housing includes an opening for extraction of the barrier that is configured and dimensioned to prevent the barrier from becoming completely furled around the holding structure.
