Modular seating assembly

Abstract

Abstract MODULAR SEATS MOLDED OF PLASTIC MATERIAL ARE SECURELY SUPPORTED ON AN ELONGATED FRAMEWORK BY FASTENERS EXTENDING BETWEEN AND ABUTTING THE ADJACENT SIDE EDGES OF THE SEATS WHILE SERVING TO ACCOMMODATE DIFFERENTIAL LONGITUDINAL AND TRANSVERSE EXPANSION AND CONTRACTION WITH RESPECT TO THE FRAME WORK. THE FRAMEWORK INCLUDES PARALLEL SUPPORT RAILS THAT COOPERATE WITH A PERIPHERAL PLANAR AREA OR PORTION AND OVERHANGING LIPS AT THE FRONT AND BACK FOR NONSTRESSING SUPPORT OF THE SEAT MODULES. EMBOSSMENTS ON THE LIPS PROVIDE TRANSVERSE SNUGNESS. LATERALLY EXTENDING FINISH STRIPS COVER THE JOINT BETWEEN THE SEATS AND HOLD DOWN THE EDGES, AND ALSO COVER THE EMBOSSEMENTS. A SLOT IS PROVIDED ALONG EACH RAIL FOR RECEIVING A BOLT, A BARREL NUT BEING DRIVEN ON THE BOLT TO FASTEN THE SEAT MODULES IN POSITION WITH ONLY TOP DRIVE BEING APPLIED. THE BOLT HEAD IS SUFFICIENTLY NARROW TO DROP BETWEEN THE SHOULDERS OF THE SLOT WHEREUPON THE SIDES OF THE SLOT LIMIT ROTATION OF THE BOLT TO AN OBLIQUE ANGLE AND INSURE ENGAGEMENT OF THE HEAD WITH SAID SHOULDERS IN FASTENING RELATIONSHIP. THE NUT INCLUDES A CULINDRICAL BODY HAVING A LOWER FACE FOR ENGAGEMENT WITH THE FRAMEWORK IN FRICTIONAL LOCKING RELATIONSHIP-, THE BODY BEING SUBSTANTIALLY THE SAME LENGTH AD THE THICKNESS OF THE PANELS (SUCH AS THE FINISH STRIP AND SEAT OR TRANSPORT TRAILER SKIN) TO OBVIATE COMPRESSION STRESSES WITHIN SAID PANELS AND ALLOW A FLOATING INTERCONNECTION FOR DIFFERENTIAL EXPANSION AND CONTRACTION AND MECHANICAL VIBRATION.
