Collapsible square

Abstract

A collapsible square constructed according to the principles of the present invention includes a first elongated rigid leg having first and second ends and a second elongated rigid leg having first and second ends. The second elongated rigid leg is pivotally connected at its first end to the first end of the first elongated rigid leg. The collapsible square further includes a hypotenuse member comprising two elongated rigid leg portions. A first of the leg portions of the hypotenuse member and a second of the leg portions of the hypotenuse member have their first ends pivotally connected to the second end of the first elongated rigid leg and the second end of the second elongated rigid leg, respectively. The first of the leg portions and the second of the leg portions have second ends thereof connected to one another in a manner which permits the hypotenuse member to be folded. The first leg, the second leg, and the hypotenuse member are connected to one another so as to be movable between 1) a storage position wherein the first leg, the second leg, and the hypotenuse member are disposed in linear overlapping relation with one another, and 2) a deployed position wherein the first leg, the second leg, and the hypotenuse member form a right triangle. A releasable lock structure disposed at the second ends of the first and second leg portions is constructed and arranged to releasably lock the first leg, the second leg and the hypotenuse member in the deployed position.
