Abstract: A modular storage system for installation on a floor includes a plurality of carts. Each cart includes a base that generally has a length that separates opposed ends of the base, a storage structure that is operably attached to and carried by the base, at least three pivotable wheel assemblies, the wheel assemblies being operably attached to and extending below the base to provide a rolling surface adapted to roll on the floor, and at least one track follower mechanism that is operably attached to one end of the base and having at least a portion of which is selectively vertically movable to engage the track.

Abstract: A convertible cart readily convertible between a cart configuration and a table configuration. A leg coupled to each end of the convertible cart is shiftable between a ground-clearing position as a cart and a ground-engaging position as a table. A coupling mechanism couples the leg to a chassis and includes a locking element and a coupling member with two gravity seats. To shift between a cart configuration and a table configuration, the locking element is disengaged from the first gravity seat, the leg is rotated between the ground-clearing position and the ground-engaging position, and the locking element is engaged with the second gravity seat.
