Description
BACKGROUND OF THE INVENTION
The present invention pertains to movable storage unit assemblies
and more particularly to movable storage unit assemblies including
a base storage unit and at least one auxiliary storage unit
supported in part by the base unit.
Movable storage units are well known and widely utilized because
they permit maximum utilization of storage space in restricted
areas. Such storage units are particularly useful for shelves and
cupboards. Since the storage units are movable the area necessary
to store the unit and permit access thereto is equal to the total
area of the movable storage units plus the access space necessary
to remove and insert objects to be stored. That is, in order to
remove or insert an object in one storage unit the other storage
units are moved to provide an access space adjacent the one storage
unit; and, accordingly, the access space may be provided adjacent
any of the storage units.
When stationary storage units are utilized, access spaces must be
provided adjacent each storage unit to permit removal and insertion
of objects. Even though the number of access spaces may be reduced
by placing two stationary units adjacent one another and providing
the access spaces on the opposite sides, the amount of space
required for the utilization of stationary storage units is
undesirable where storage space is limited.
One disadvantage of conventional movable storage units is that they
are relatively expensive in comparison with stationary storage
units. Movable storage units normally incorporate a drive system
which may be a central drive whereby all of the movable storage
units are driven by a single motor by means of a cable or a chain,
or an individual drive whereby each movable storage unit includes a
motor. Conventional assemblies of movable storage units are
extremely difficult to extend or expand, particularly those
assemblies utilizing a central drive.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a
movable storage unit assembly that avoids the disadvantages and
expense of conventional movable storage units.
Another object of the present invention is to reduce the peripheral
equipment necessary to support a movable storage unit assembly.
A further object of the present invention is to utilize a base
storage unit of a movable storage unit assembly to support one side
of an auxiliary or side storage unit.
The present invention has another object in that a base storage
unit of a movable storage unit assembly is supported on runners
riding on a pair of parallel rails and is utilized to provide
support for the sides of a pair of auxiliary storage units each of
which includes runners adapted to ride on one rail of a second pair
or rails.
Some of the advantages of the movable storage unit assembly of the
present invention over conventional movable storage unit assemblies
are that the number of rails necessary to support the assembly is
reduced, that the assembly may be disassembled for transportation
purposes and to permit entrance into areas having narrow
passageways through which an entire assembly could not be moved,
that due to the simplified structure and reduction in peripheral
equipment manual labor during installation is reduced to a minimum,
that existing assemblies may be expanded or reduced without
changing or altering the drive system in any manner whether a
central, individual or hand drive is utilized, and that lateral
storage space is fully utilized with a minimum of equipment and
expense.
The present invention is generally characterized in a movable
storage unit assembly including a base storage unit having runners
disposed on both sides and adapted to ride on first and second
parallel rails, and an auxiliary storage unit having a first side
and a second side, means connecting the first side of the auxiliary
storage unit with a side of the base storage unit, and a runner
disposed on the second side of the auxiliary storage unit and
adapted to ride on a third rail parallel to the first and second
rails.
Further objects and advantages of the present invention will become
apparent from the description of the preferred embodiment as shown
in the accompanying drawings.

unit assembly according to the present invention.
FIG. 2 is a schematic side elevational view of the assembly of FIG.
1 taken along lines II-II.
DESCRIPTION OF THE PREFERRED EMBODIMENT
A movable storage unit assembly according to the present invention
is shown in FIG. 1 and includes a base storage unit 10 and two side
or auxiliary storage units 12 and 14. Base storage unit 10 is
supported on runners 16 and 18 disposed at either side of the unit,
respectively, to ride on a pair of parallel rails or tracks 20 and
22. As best shown in FIG. 2, it is desirable to provide two runners
spaced from each other in the direction of travel of base storage
unit 10 on rails 20 and 22 in order to stabilize the unit and to
prevent tipping.
Auxiliary storage units 12 and 14 are connected with base storage
unit 10 for support by means of bolts 24 and 34. Resilient means
such as rubber springs may be utilized with or instead of the bolts
and may be inserted between the side edges of base storage unit 10
and auxiliary storage units 12 and 14 in order to act as buffers
between the base and auxiliary storage units and to permit slight
variations in movement between the base storage unit and the
auxiliary storage units without undue wear on the bolts 24 and 34
and the connections on the side edges of the units. Furthermore,
the resilient connecting means compensate for unevenness in the
foundation supporting the rails and permit the assembly to move
around curves in the rails with little difficulty. Auxiliary
storage unit 12 has a runner 26 disposed at the side opposite the
side supported by base storage unit 10, and runner 26 is adapted to
ride on a rail 30 arranged in parallel with rails 20 and 22.
Similarly, auxiliary storage unit 14 has a runner 28 disposed at
the side opposite the side supported by base storage unit 10, and
runner 28 is adapted to ride a rail 32 arranged in parallel with
rails 20, 22 and 30.
Auxiliary storage units 12 and 14 are thus supported on only one
side by runners and are supported on the other side by base storage
unit 10. Accordingly, the second rail normally required to support
a storage unit is obviated thereby reducing the peripheral
equipment necessary to install the assembly of the present
invention. Clearly auxiliary units may be added or removed, as
described, to provide an extremely flexible system.
Runners 16, 18, 26 and 28 may comprise any easily slidable surface;
however, the runners are preferably wheels to reduce friction to a
minimum. The stability of base storage member 10 in cooperation
with the horizontal and vertically spaced bolts 24 and 34, as shown
in FIG. 2, permit the use of only one runner with the side of each
auxiliary storage unit without the danger of tipping; however, a
plurality of runners spaced in the direction of travel of the
auxiliary storage units may be utilized as a safety precaution.
The base and auxiliary storage units may take any conventional form
and may include shelves and doors to facilitate storage and access.
Base storage unit 10 may be utilized with only one auxiliary
storage unit without causing imbalance due to the alignment of
support bearings obtained by making the support structure for each
storage unit identical except for the number of runners.
Inasmuch as the present invention is subject to many variations,
modifications and changes in detail, it is intended that all matter
described in the foregoing specification or shown in the
accompanying drawings shall be interpreted as illustrative and not
in a limiting sense.
