Abstract
A barrier-free drainage apparatus includes a trough positioned adjacent the front edge of a platform. The trough has a bottom wall which is positioned below the front edge of the platform, and at least one outlet opening in fluid flow communication with a drain pipe. A grate is positioned inside the trough and has an upper, generally horizontal portion with a plurality of apertures therethrough. The upper portion is supported such each that said upper portion is spaced apart from the trough bottom wall in a generally horizontal position and a top surface of the upper portion is substantially the same height as the front edge of the platform. Another aspect of the invention is the configuration of the outlet openings. A plurality of spaced apart, elongated insert receptacles depend from the bottom wall. The insert receptacles have side wall means and a horizontal base which define a cavity, and each base has two spaced apart outlet openings therein adjacent opposing ends of the base. Elongated inserts have a hole adjacent one end thereof and are adapted to fit into the insert receptacles. A top surface of each insert slopes downward toward the hole. When assembling the drainage apparatus, the inserts are placed in the insert receptacles so that the insert hole is in alignment with one of the receptacle base outlet openings.
