Push Back Storage Rack System

View page
US Patent:
6851562, Feb 8, 2005
Filed:
Oct 4, 2001
Appl. No.:
09/971752
Inventors:
Theodore S. Gorniak - North East PA, US
John B. Pellegrino - Erie PA, US
James A. Courtwright - North East PA, US
Assignee:
Ridg-U-Rak, Inc. - North East PA
International Classification:
A47F005/00
US Classification:
211 592, 211151, 414276, 414286
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.

Storage Rack Vibration Isolators And Related Storage Rack Systems

US Patent:
7249442, Jul 31, 2007
Filed:
Apr 10, 2006
Appl. No.:
11/279161
Inventors:
John B. Pellegrino - Erie PA, US
James A. Courtwright - North East PA, US
Robert Michael - Erie PA, US
Assignee:
Ridg-U-Rak, INc. - North East PA
International Classification:
E04B 1/98
F16M 13/00
US Classification:
521678, 248564
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.

Storage Rack Vibration Isolators And Related Storage Racks

US Patent:
7263806, Sep 4, 2007
Filed:
Apr 10, 2006
Appl. No.:
11/279138
Inventors:
John B. Pellegrino - Erie PA, US
James A. Courtwright - North East PA, US
Robert Michael - Erie PA, US
Assignee:
Ridg-U-Rak, INc. - North East PA
International Classification:
E04B 1/98
F16M 13/00
US Classification:
521678, 248564
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.

Front Beam And Tension Rod Arrangement For Push Back Rack Storage System

View page
US Patent:
20020139766, Oct 3, 2002
Filed:
Mar 26, 2002
Appl. No.:
10/106278
Inventors:
James Courtwright - North East PA, US
International Classification:
A47F005/08
US Classification:
211/191000, 211/190000, 211/151000
Abstract:
A beam and tension rod arrangement is for use with a push back storage rack system. A front beam extends between two front vertical uprights across the loading position of one or more cart lanes. An interior structural cross support extends between two interior vertical uprights that are located at points along the length of each cart lane. Diagonal tension rods extend from each end of the interior structural cross support to points on the front beam's structural angles that are adjacent the middle portion of the front beam. When a loaded cart collides with the front beam, the majority of the collision forces are directed toward the middle portion of the front beam, which exerts diagonal tension forces on the tension rods between the front beam and the interior structural cross support. The diagonal tension rods serve to brace the front beam against flexing, transferring much of the impact strain to the interior structural cross support. In doing so, the tension rods tend to more evenly distribute the impact forces among the system's multiple interior vertical uprights to provide heightened resistance to beam warping even after extended use.

Upright Protector

US Patent:
20140196997, Jul 17, 2014
Filed:
Jan 16, 2014
Appl. No.:
14/157121
Inventors:
- North East PA, US
James A. Courtwright - North East PA, US
Assignee:
Ridg-U-Rak, Inc. - North East PA
International Classification:
F16F 7/00
E01F 15/14
US Classification:
188377, 267139
Abstract:
A protector allows for the engagement and protection of a segment of an upright from an impact force by an external object and for absorbing and damping the resulting impact force. The protector comprises a protector body and a shim. The protector body allows engagement and positioning of the protector on at least a segment of the upright. The protector body is also partially constructed of an energy absorbing and damping material and having an outer surface and an inner surface. The outer surface is positionable to receive the impact force from the external object. The inner surface is positionable to abut the upright, when the protector is in engagement with the upright. The shim is least partially embedded in the protector body and provides increased structural support for the protector body. The shim also has a stiffness different than the stiffness of the protector body.
