ABSTRACT:
Plug-together joints are formed between floor members (10, 10') and drive beams (18, 18'). These connections may comprise a pin or insert (72) secured to the drive beam (18) and a box or socket (52, 54) secured to the floor member (10). Or, it may comprise a box or socket (176, 178) secured to the drive beam (18') and an insert or pin (188) secured to the floor member (10'). Alternatively the connection may comprise an abutment block (198) secured to the floor member (10") which longitudinally engages between vertical push/pull members (210, 212), or a vertical projection (226) secured to the drive beam (18") which engages between a pair of abutment blocks (198) secured to the floor member (10"). The plug-together connection is used in a reciprocating floor conveyor of a type having slide bearings (122) for the floor members (10, 10') which allow the floor members (10, 10') to be snapped into place from above. The floor may also include hold down members (90) which are secured to the guide beams (14) for the floor members (10, 10') and which are also constructed to allow the floor members (10, 10') to be snapped into place from above. The hold down members (90) include hold down wings (100, 102) which, when the floor member is in place, locate lower edges (104, 106) above inner edge portions (84, 82) of the floor member (10, 10'). This puts the hold down wings (100, 102) into positions to block upward movement of the floor members (10, 10').
