Screen frame

摘要

A screen support frame comprising, a perimeter disposed in a horizontal plane, defining a vertical direction normal to said plane, said perimeter reinforced by an arrangement of reinforcing wires, said arrangement comprising a first array of substantially parallel structural wires extending between opposing regions of the perimeter in a first horizontal plane, a second array of substantially parallel structural wires extending between opposing regions of the perimeter in a second horizontal plane, said first and second arrays of structural wires being aligned at an angle to each other and in contact with each other thus forming a plurality of contact points between structural wires of the first and second array respectively, the arrangement further comprising at least one additional structural wire, said additional structural wire extending between opposing regions of the perimeter and being positioned parallel to, and substantially vertically spaced from, a wire in the first array of structural wires, and in contact with wires of the second array.

1. A screen support frame comprising, a perimeter disposed in a horizontal plane, defining a vertical direction normal to said plane, said perimeter reinforced by a first arrangement comprising a first array of substantially parallel first structural wires extending between opposing regions of the perimeter in a first horizontal plane, a second array of substantially parallel second structural wires extending between opposing regions of the perimeter in a second horizontal plane, said first array of first structural wires and second array of second structural wires being aligned at an angle with respect to each other and in contact with each other thus forming a plurality of contact points between the first structural wires of the first array and the second structural wires of the second array, the arrangement further comprising at least one additional structural wire, said additional structural wire extending between opposing regions of the perimeter and being positioned parallel to, and substantially vertically spaced from, a first structural wire in the first array of first structural wires, and in contact with one or more structural wires in the second array of second structural wires such that portions of the one or more second structural wires in the second array of second structural wires are positioned between, and in contact with, the at least one additional structural wire and the first structural wire in the first array of first structural wires.
