Abstract:
1. A public seating system with interchangeable modular web-design perforated seats and web-design perforated backs comprising: a. a support assembly consisting of a generally cylindrical and solid support beam with a longitudinal channel cut or etched into a bottom surface of said support beam, said channel running the entire length of said support beam, and a connecting screw opening on both ends of said support beam said connecting screw opening threaded to receive a connecting screw; b. an inverted Y-shaped side support member with its prongs acting as feet for said side support member and its neck extending vertically to support a curvilinear and contoured arm rest attached perpendicularly thereto, said neck of said side support member having a cylindrical indentation cut into each of its sides directly opposite each other with a circular hole cut through the center of said indentation to accommodate said connecting screw, said indentations dimensioned so that said support beam fits snugly into said indentation on the inside of said side support member and said connecting screw fits snugly into said indentation on the outside of said side support member, said indentation on the inside of said support member having a ridge extending upward from the bottom surface of said indentation and dimensioned to fit snugly into said channel in said support beam; c. one to six seat assemblies each of which is attached said support beam by means of a semi-cylindrical mounting sleeve surrounding a lower half of said support beam and being coupled to the semi-cylindrical base of said seat assembly, said mounting sleeve having a ridge extending upward from an inside-bottom surface of said mounting sleeve and dimensioned to fit snugly into said channel in said support beam, said seat assembly having four seat support members extending equilaterally outward and curving upward from the semi-cylindrical base and having a horizontally flattened distal end with threaded screw holes centered therein, said seat assembly having a fifth seat support member extending outward directly to the rear and curving upward from its base and having a generally vertically flattened distal end with a threaded screw hole centered therein; d. an arm rest attached to said support beam, by means of a semi-cylindrical mounting sleeve surrounding said the lower half of said support beam and being coupled to the semi-cylindrical base of the arm rest, said mounting sleeve having a ridge extending upward from the inside-bottom surface of said mounting sleeve and dimensioned to fit snugly into said channel in said support beam; e. a back assembly attached to each seat assembly, said back assembly having four back support members extending equilaterally outward and curving upward from its flattened base and having a horizontally flattened distal end with threaded screw holes centered therein, said base having a threaded screw hole centered therein, said back assembly fixably mounted onto said seat assembly, and f. a perforated, flexible, generally, rectangular, flat, reversible modular tension membrane dimensioned to precisely fit onto said seat assembly or said back assembly interchangeably, said membrane attached to said seat assembly and said back assembly at said screw holes at said distal ends of said seat assembly and said back assembly, said membrane having ribbing extending equilaterally outward from its center such that any force exerted on said membrane is distributed equally along said ribbing.
