Abstract

A kit for converting a standard swing-type gate into a rolling cantilever-type gate. The kit consists of commercially available roller assemblies and guide roller assemblies with associated attaching hardware and a unique top-rail extrusion. The top-rail extrusion is constructed in one piece with a flat ribbed side face having shoulders. Said shoulders either bolt directly to the gate in a horizontal orientation or attach to the gate horizontally with contoured brackets selected to fit the gate's structural members. One side of the top-rail extrusion is provided with a longitudinal compartment having a downward facing opening along its length. The compartment serves as a trackway for upper roller assemblies which are secured to support posts. Said upper roller assemblies access the compartment by way of the downward facing opening and support the gate. Bottom guide roller assemblies also attach to the support posts and are positioned with at least one wheel of each guide roller assembly on each side of the gate's bottom gate rail.

Dependent claims

A gate conversion kit for converting a conventional swing-type gate to a cantilever-type gate for spanning an opening defined by a gate-receiving side and a gate-supplying side of a perimeter fence comprising a one-piece horizontal top-rail extrusion having a flat vertical plate for engaging the gate along a first side of the plate and in general parallel alignment with the gate, a compartment extending horizontally along the top-rail extrusion for its entire length, said compartment attached to the vertical plate on a second side of said plate opposite the side which is adapted to engage the gate, said compartment having a downward facing opening extending parallel to the plate and formed by two horizontal lower lips, an upper shoulder on the vertical plate extending above the compartment, a lower shoulder on the vertical plate extending below the compartment, the upper and the lower shoulders being provided with holes to permit connection to said gate, at least one upper roller assembly adapted to be secured to a supporting post located on the gate-supplying side of the fence, said upper roller assembly engaging the compartment through the downward facing opening for supporting the gate and for moving the gate between open and closed positions.
