  • Patent number: 6938882
    Abstract: An apparatus for internally framing a vinyl gate suitable for use with vinyl fencing provides completely hidden structures formed of sheet metal and assembled for greater strength and rigidity. Beams may be formed as channels from sheet metal, which may be placed together, with open edges of the channel juxtaposed and positioned within each other, in order to provide fully closed perimeters for beams. Various types of corner ties are provided to support loads and squareness required between vertical and horizontal members of the frame. In various embodiments, vinyl sleeves may be placed over various beams before or after the beams have been fully assembled, as appropriate, possible, or required. In certain embodiments, the entire systems of gate framing may be shipped in a long format appearing primarily as linearly-extending, channel-shaped stock. Likewise sheathing can ship as long stock.
