An elevator bridge apparatus for use between an elevator floor and a building floor defining a first gap between the elevator floor and the building floor, wherein the apparatus comprises,
- a first horizontal support plate spaced from a second horizontal support plate in a coplanar coextensive relationship, wherein the first horizontal support plate is spaced from the second horizontal support plate a second gap less than the first gap, and
- including securement means to adjustably secure the first horizontal support plate relative to the second horizontal support plate, and
- the first horizontal support plate includes an interior edge positioned adjacent the second horizontal support plate, and the second horizontal support plate includes a second horizontal support plate interior edge spaced from and adjacent the first horizontal support plate, and a first vertical plate mounted orthogonally to the first horizontal support plate interior edge, and a second vertical plate mounted orthogonally and integrally to the second horizontal support plate interior edge, wherein the first vertical plate and the second vertical plate are spaced apart in a parallel coextensive relationship spaced apart a spacing equal to the second gap, and the securement means includes a plurality of connecting rods directed medially and orthogonally through the first vertical plate and the second vertical plate, and wherein each connecting rod of said plurality of connecting rods is spaced apart a predetermined distance from the connecting rod to either side and each connecting rod includes a first vertical plate interior fastener and a first vertical plate exterior fastener mounted to a respective interior and exterior surface of the first vertical plate on opposed sides thereof, and a second vertical plate interior fastener and a second vertical plate exterior fastener mounted to an interior and exterior surface of the second vertical plate on opposed sides thereof, wherein the fasteners permit spacing of the first vertical plate relative to the second vertical plate.
