Abstract
Abstract A movable aisle storage system is provided having rail and panel connector units which perform the dual functions of forming the rails and interconnecting the deck panels of the system track and deck assembly. Each connector unit has a substantially cylindrical rail portion and a depending support portion having a pair of upwardly and outwardly extending flange sections which support and secure the sides of the deck panels. Levelling screws threadedly engaging the unit support portion are seated in a channel to facilitate system installation and prevent floor damage. Flexible seal strips are used between the rails and panels thereby reducing system maintenance and permitting access to the levelling screws after system installation. Rail sections are joined to form an extended track by a self-tightening rail section joiner having a pair of tapered head machine screws which threadedly engage holes in abutting rail sections. A joiner member overlies the rail section holes and has openings to receive the screws. The member openings have a center-to-center distance less than the center-to-center distance of the section holes so that rotation of the screws causes the section ends to be forced together tightly. An anti-tip bar may be secured to a movable carrier so that a substantially cylindrical bore in the bar slidably receives a rail and prevents carrier tipping. A wheel and housing assembly for the movable carriers having an axle, a wheel and two interchangeable support members is assembled with a simple peening operation.
