Abstract: A storage rack vibration isolator for a storage rack system installed on a floor comprising a first mounting plate connectable to the storage rack system, a second mounting plate connectable to the floor. An elastomeric component extending between these mounting plates and is operatively attached to them so that during seismic events the first and second mounting plates remain attached to the elastomeric component as the elastomeric component is placed in shear while the first and second mounting plates are able to move in planes substantially parallel to each other. The elastomeric component comprises at least one elastomeric member made of material that is capable of absorbing and dissipating the energy of ground movement imparted to the storage rack system during seismic events, while the material enables the storage rack system to move a sufficient distance relative to the floor to lower the natural frequency of the storage rack system in at least one horizontal direction.

Abstract: A storage rack system to be installed on a floor has a plurality of columns, is more flexible in a down aisle dimension than it is in a cross aisle dimension, and has at least a first column and a second column adjacent one another in the cross aisle dimension. A storage rack vibration isolator for use with this storage rack system comprises at least one seismic vibration absorption and dissipation structure constructed to be located primarily between the first and second columns to reduce the storage rack system's natural frequency in at least the cross aisle dimension. The seismic vibration absorption and dissipation structure includes a first member connectable to the storage rack system and a second member connectable to the floor. At least one column support assembly is mountable to at least the first and second columns to enable them to move with respect to the floor. A structure limits the movement of the first and second columns to substantially the cross aisle dimension.

Abstract: A push back storage rack system for storing multiple loads in a single inclined cart lane. Each lane contains at least two wheeled carts, each cart being capable of receiving and storing multiple pallet loads. The carts are vertically spaced so that they can freely slide underneath each other when unloaded. Beginning with the first or lowest level cart in the system, each successively higher cart is also wider and longer than the cart immediately beneath it. The carts are positioned on at least one but potentially two pairs of rectangular tracks or tubes, each tube being capable of supporting two or four individual carts, depending on how the carts are constructed and installed on the tubes. The tubes are mounted on an incline away from a loading end of each lane so that when loads are placed on or are removed from a lane, the carts are biased toward the loading end of the lane by the force of gravity. Each tube has a single, planar upper support surface which has inside and outside edges.

Abstract: An automatic locking apparatus releasably locks together a studded end plate connector to a notched vertical frame column of a storage rack. The automatic lock includes a vertical lever positioned adjacent one surface of an end plate connector when the end plate connector is mounted on a vertical frame column. A locking pin and tension support extend from the inside face of the vertical lever through the end plate connector. The tension support has a protruding end extending past the end plate connector and a tension device mounted on the protruding end to create a force for pulling the inside face of the vertical lever toward one surface of the end plate connector. The locking pin has a length that allows it to extend through the top of a notch or other aperture in the frame column when studs of the end plate connector are positioned in the bottom of corresponding notches in the frame column, preventing withdrawal of the studs from the notches.
