Devening's invention relates to a high density system of movable storage racks
in which groups of racks are arranged side by side in a row with the racks being
selectively movable individually or in groups so as to leave a loading and unloading
space between any two of the racks. As shown in Figure 1, a high density, mobile
storage system 10 comprises groups of shelving racks 13 arranged in rows 14. The
shelving racks 13 each comprise four corner posts 15 which support multiple shelves
16. Casters 17 are mounted in the lower end of each of the four corner posts 15 of
each rack. These casters support rotatable wheels 18 which rotate about a horizontal
axis. The wheels of the casters, though, do not swivel or pivot about a vertical axis, but
are fixed to the posts such that the wheels all rotate about parallel, horizontal axes,
which axes extend perpendicular to the length of the rows of shelving racks. The
endmost ones of the shelving racks 13 in each row of racks 14 are fixedly secured to
guide rails 25 associated with that row. In the assembly of the shelving racks 13 to the
guide rails 25, a loading and unloading space is left between two of the racks. Because
of the presence of this unloading and loading space 35, all but the endmost racks may
