1. A foldable welding screen, comprising:
first and second elongate members each having a first end, a second end, and an intermediate point, the intermediate point comprising a pivoting connection, wherein the pivoting connection of the intermediate point has a pivot axis extending perpendicular to the respective elongate member, the first ends of the first and second elongate members being pivotally connected at a first corner connection and the second ends of the first and second elongate members being pivotally connected at a second corner connection, each of the first and second corner connections pivoting freely about a respective pivot axis; a stabilizing member having a first portion that is pivotally connected to the intermediate point of the first elongate member and a second portion that is pivotally connected to the intermediate point of the second elongate member, the first portion of the stabilizing member being movable relative to the second portion of the stabilizing member; a flexible substrate attached to the first elongate member and the second elongate member; the first and second elongate members having an erected position and a collapsed position, wherein, in the collapsed position:
the first and second elongate members are folded about the pivot axis of the pivoting connections at the respective intermediate points such that the first and second ends are adjacent;the first and second elongate members are pivoted about the first and second corner connections such that the intermediate points are adjacent; andthe first and second portions of the stabilizing member are pivoted to extend from the intermediate points of the first and second elongate members toward either of the first and second ends of the first and second elongate members; and in the erected position:
the first and second ends of the first and second elongate members are spaced apart with the intermediate point of each first and second elongate member being non-collinear with the first and second ends;the first elongate member is pivoted about the pivotal connections at the first and second ends relative to the second elongate member such that the first elongate member extends outward from the second elongate member;the stabilizing member portions being engaged to support the orientation of the first elongate member relative to the second elongate member; andthe flexible substrate extending over the stabilizing member between the first and second elongate members to define a welding screen. |
