Description
BACKGROUND OF INVENTION
[0001] This invention relates to a moveable shelf and partitioning
system and more particularly to an improved type of moveable
shelving and partitioning system that offers greater flexibility
and versatility than those presently in use.
[0002] There are known storage systems that include a number of
moveable shelves that are supported for movement along a work area
on tracks or guide rails that are affixed to the floor of the area.
These shelves can be compressed in abutting relationship to open up
space and then moved to offer access to the individual shelf areas
for the insertion and removable of articles there from. These types
of devices have wide application and considerable utility.
[0003] However, the requirement for having rails or tracks in the
floor by which the shelves can be moved means that the area must be
specially adapted to utilize this type of system. Also, once
converted to this arrangement, the utility of the area is somewhat
compromised.
[0004] In addition, once in position the types of moveable shelves
aforedescribed are not easily moved to another location. If they
are to be moved, then that location must also be modified to
provide the necessary guide rails on which the shelves can be
mounted.
[0005] It is, therefore, a principal object to this invention to
provide an improved moveable shelf arrangement that does not
require guide rails for its operation.
[0006] It is a further object to this invention to provide a
moveable shelf that can be supported on any type of floor and can
be freely moved from position to position to optimize space
utilization.
[0007] In addition to having moveable shelving, similar systems
have been employed for partitioning rooms where a number of upright
panels are mounted by wheels and guide rails and so that they can
be moved so as to divide the room into various segments. In
addition to having these partitions moveable on rails on the floor,
they are also supported often from above on overhead rails.
[0008] Again, this not only means that the room must be specially
constructed in order to contain and utilize these moveable
partitions, but also the ability to change the shape of the
individual compartments that are divided is severely limited. That
is, the width of the room is generally maintained constant and the
partitions divide the room into areas having the same or different
lengths.
[0009] It is, therefore, a further principal object to this
invention to provide a moveable partitioning system for a room that
offers greater flexibility in the form of the partitions that can
be created and the number of partitions that are possible.
[0010] It is a further object to the invention to provide a
moveable partitioning system of this type wherein the partitions
also permit access between the divided compartments of the
room.
SUMMARY OF INVENTION
[0011] A first feature of the invention is adapted to be embodied
in a storage arrangement comprising a shelf adapted to receive
articles. The shelf has a base and a drive unit disposed beneath
the base and adapted to support the shelf on a floor for movement
there along. The drive unit is comprised of a pair of wheels
supported for rotation upon the base about parallel, spaced axes. A
drive and support belt is trained around the wheels and has a lower
flight for engaging the floor and supporting the shelf thereupon.
The drive unit further includes a drive for rotating at least one
of the wheels for driving the belt and effecting movement of the
shelf along the floor.
[0012] Another feature of the invention is adapted to be embodied
in a room partitioning system for partitioning an area having a
floor and enclosing, fixed walls. The partitioning system comprises
a panel supported on the floor by a drive system. The drive system
being operable to move said panel along the floor in directions to
partition the area into segments of the desired size and shape.

DETAILED DESCRIPTION
[0028] Referring now in detail to the drawings and initially to the
embodiment of FIGS. 1 through 9 and beginning by specific reference
to FIG. 1, a moveable shelf constructed in accordance with this
embodiment of the invention is identified generally by the
reference numeral 31. The moveable shelf 31 is adapted to be
supported for movement along a floor 32 of any common type in a
manner to be described.
[0029] The shelf 31 includes an upper shelf assembly 33 that is
mounted on a base, indicated generally by the reference numeral 34.
The shelf assembly 33 can be of any material and construction and,
for example, can include adjustable shelves that are held by side
pieces. Since those skilled in the art will readily understand the
various forms that the shelving may take, further description of
that is believed to be unnecessary.
[0030] The base 34 has a construction as best shown and as will be
described later by reference to FIGS. 2 through 7. However, it
includes driving wheels 35 and driven wheels 36 that are
interconnect by an endless belt 37 which provides the direct
support for the shelf 31 on the floor 32.
[0031] Referring now primarily to FIGS. 2 through 6, the base 34 is
comprised of a sheet metal assembly comprised of a planar type
upper surface 38 and a pair of folded down side surfaces.
Reinforcing U-channels 39 may be affixed at spaced locations along
the horizontal surface 38 to add rigidity to the construction. A
driving shaft 41 and driven shaft 42 are journaled in spaced
transverse relationship by means of a plurality of pillow blocks 43
that are affixed to and form a part of the base 34. Specifically,
these pillow blocks 43 are fixed to the under side of the panel
surface 38. Bearings 44 carried by these pillow blocks 43 complete
the journaling of the shafts 41 and 42 in the base 34.
[0032] The driving wheels 35 are affixed at spaced locations and
between pairs of the pillow blocks 43 and bearings 44 to the
driving shaft 41. In a like manner, the driven wheels 36 are
affixed to the driven shaft 42. In order to facilitate assembly and
machining, the shafts 41 and 42 need not be continuous shafts but
can constitute shaft segments that are joined together by couplings
45.
[0033] The drive belts 37 may be of the toothed type and can
cooperate with sprocket teeth on the driving wheels 35 and driven
wheels 36. In addition and if desired, a plurality of sprockets 46
may be fixed along the lengths of the shafts 41 and 42 and
interconnected by a chain (not shown).
[0034] The driving shaft 41 is driven by one or more electric
motors 47 that are mounted on a mounting bracket assembly 48 on the
underside of the plate 38. These electric motors 47 have pinion
gears 49 affixed to their drive shafts. The pinion gears 49
cooperate with gears 51 fixed to the driving shaft 41 so as to
drive it. These motors 47 are of the reversible variable speed type
and are control by a suitable control panel 49 mounted on the side
of the shelves 31 (FIG. 1).
[0035] Although the drive belts 37 may be made of any suitable
material and my, as noted above, have their inner flight toothed to
provide a non-slip driving relationship with the driving wheels 35
and driven wheel 36, it may be desirable to provide an arrangement
for retaining the drive belt against axial movements. FIGS. 10 and
11 show an embodiment to how this may be accomplished. Aside from
this anti-slipping arrangement, the construction is the same as
that previously described and, therefore, the components which are
the same have been identified by the same reference numerals and
will not be described again, except insofar as is necessary to
understand the construction and operation of this embodiment.
[0036] In this embodiment, the driving and driven wheels 35 and 36
have annular members 51 affixed to their outer periphery and which
extend radially outwardly beyond the outer periphery of the wheels
35 and 36. Thus, as seen in FIG. 11, these extending portions
provided by the annular members 51 will insure that the belts 37
are maintained in axial position on the wheels 35 and 36.
[0037] Depending upon the width or depth of the shelves 31, it may
be desirable to provide further support on the floor 32 and
specifically for the back up side of the belt 37. FIG. 12 shows
such an arrangement where, in addition to the driving wheel 35 and
driven wheel 36 mounted on the shafts 41 and 42, respectively,
there are a plurality of back up rollers 61 that are carried by
shafts 62 that are journaled in the pillow blocks 43 and bearings
44. Thus, more back up contact is provided between the drive belt
37 and the floor 32.
[0038] Also, the width of the belts 37 may be changed from a narrow
width to a wide width as shown in FIG. 13 where the different
widths are shown at 37a, 37b and 37c. Although the support is
greater when the width is increased, this provides a larger
resistance to driving and requires larger driving motors.
[0039] FIG. 14 shows how the inter-positioning of the belt 37
between the driving and driven wheels 35 and 36 and the floor 32
provides a cushioning between the wheels 35 and 36 and the floor
32. Hence, the device can be utilized on a wide variety of floor
materials and, special rails embedded in or mounted on the floor 32
are not required. The supporting portion of the drive belt is
indicated in FIG. 14 by the reference numeral 63.
[0040] It has been noted in the embodiment as thus far described,
there are provided two electric drive motors 47 spaced transversely
across the length of the shelf 31. Of course, the number of drive
motors can be changed. Also although electric motors are
illustrated, other means for rotating the driving shaft 41 can be
employed. These can include providing a manual crank handle mounted
on the side of shelf 31 for rotating the shaft 41.
[0041] In the embodiment as thus far described, all of the drive
wheels 35 are mounted on a common shaft and are driven. Depending
upon the loads to be expected and the specific environment, it is
not necessary that all wheels be directly driven. FIGS. 15 through
17 are partial views which can be considered to be similar to FIGS.
3 and 6 and show how some wheels, again indicated by the reference
numerals 35 and 36, can be mounted on stub shafts 81 which are
journaled in the pillow blocks 43 and bearings 44. In this case,
these drive belts 37 are only driven through their contact with the
floor.
[0042] In connection with an arrangement wherein the driving wheels
that are driven by an electrical motor or other force are not all
coupled to each other, it would be possible to provide controls
whereby one motor can be driven and the other remains stationary or
is rotated in a reverse direction. In this way, it is actually
possible for the shelf to be driven in an arcuate fashion. The
possibilities of such various movements should be readily apparent
to those skilled in the art without further description or
illustration.
[0043] In addition to shelving for storage purposes, the moveable
partition of the type described also can be employed to partition a
room into various areas. FIGS. 18 and 19 through 21 show two such
embodiments.
[0044] Referring first to the embodiment of FIG. 18, a room,
indicated generally by the reference numeral 101 has a generally
rectangular floor 102 closed by two long side walls 103 and 104 and
two shorter end walls 105 and 106. In addition, the room is closed
by a roof which is not illustrated.
[0045] A partitioning assembly comprised of a first partition,
indicated generally by the reference numeral 107 and a second
partition indicated generally by the reference numeral 108 are
supported for movement along the floor 102 by any of the types of
drives previously described and particularly those shown in the
earlier figures. Since the driving arrangement is the same at that
previously described, it is not illustrated since it is not
believed that a further illustration is necessary for those skilled
in the art to understand this feature of the invention.
[0046] In this embodiment, each partition 107 and 108 has the same
overall configuration and they are of a width that spans the width
of the room 101. Thus, access to the two room areas that are formed
when the partitions 107 and 108 in back-to-back relationship, can
be accessed through side doors 109 and 111. It should be noted that
the partitions 107 and 108 can be moved together to vary the sizes
of the room areas thus formed. In addition the partitions 107 and
108 can be moved toward and away from each other to provide a third
room area between the two partitions 107 and 108.
[0047] Passage to this third room area is possible through doors
112, only one of which appears in this figure, formed in alignment
with each other in the partitions 107 and 108. Thus, when the
partitions are in back-to-back relationship, access between the
room areas formed is obtained by opening both of the doors 112 in
the partitions 107 and 108.
[0048] If the partitions 107 and 108 are spaced from each other,
then the area between the two partitions can be accessed through
either the door 112 and the partition 107 from one outer room area
or through the door 112 in the partition 108 from the remaining
outer area of the room.
[0049] On the sides of the partitions 107 and 108 outwardly from
the doors 112, there are further areas provided indicated by the
reference numerals 113 and 114. These partition areas 113 and 114
may be provided with shelving for storage, bookshelves, lockers or
other types of storage systems.
[0050] In this embodiment, it is desirable to have the partitions
107 and 108 move so that they are maintained in parallel
relationship to each other and to the end walls 105 and 106. For
this purpose, guide strips 115 are provided in the area above the
partitions 107 and 108 and are sensed by appropriate sensors
carried by the partitions 107 and 108. These sensors transmit
signals to the drive motors, assuming a separate motor is utilized
for each side of the partitions 107 and 108, so that they will be
maintained in parallel relationship not only to each other but to
the end walls 105 and 106.
[0051] Although the necessity for this might be avoided by
utilizing interconnected drive shafts as in the first mentioned
embodiment, there are times when it is desirable to provide
separate control as for one reason or another in order to maintain
parallel relationship. That is at times, one motor should be driven
differently from the other to maintain parallel movement.
[0052] Referring now to FIGS. 19 through 21, these figures show
another type of arrangement which can offer more flexibility in the
partitioning of a room. The room, again identified by the reference
numeral 101 is also formed by two long side walls 103 and 104 and
two shorter end walls 105 and 106. Along one of the walls, such as
the side wall 103, there may be formed one or more vertical pillars
121 for a purpose which will be described shortly. The side wall
104 is formed with two doors, an outwardly opening door 122 and an
inwardly opening door 123, both of which offer access to the room
101.
[0053] A first shorter end wall partition, indicated generally by
the reference numeral 124 is supported in any of the manners
previously described. This partition is maintained in parallel
relationship to the end walls 105 and 106. A second moveable
partition 125 that is longer than the partition is supported in any
of the manners previously described. This second partition 125 is
maintained in a position parallel to the side walls 103 and
104.
[0054] The partition 124 also includes at one of its ends a door
126 which may be swung to an outward position as shown in the
figures or to an inward position flush with the end wall of the
partition 124. The partition 125 is provided with two doors that
open a common opening and which will be described shortly.
[0055] FIG. 19 shows the partitions 124 and 125 in a position
wherein they do not divide the room 101 into separate areas.
Shelves or other types of storage arrangements are formed in the
partitions 124 and 125 and can be accessed though the sides facing
the interior of the room 101 for storage purposes.
[0056] FIG. 20 shows another position of the partition 124 with the
door 126 swung to an extended position. In this position, the door
126 effectively separates the two areas A and B formed by the moved
partition 124. The room area A can be accessed from the outside
through the door 122 or from the area B by the opening of the door
126 to a flush position against the end wall of the partition 124.
The area B can be accessed through the outside by opening the door
123.
[0057] The partition 125 can also be moved transversely relative to
the partition 124 to a position as shown in FIG. 21 to divide the
area into the previously area B and two new areas, C and D. As seen
in this figure, doors 127 and 128 are formed in the partition 125
so as to permit access between the areas C and D. The area C can
communicate with the area A by opening the door 126 and the entire
areas can be accessed from the outside through either door 122 or
126.
[0058] In this embodiment, the area above the partitions 125 and
126 is also provided with guide strips and the partitions 124 and
125 provided with sensors so as to move always parallel to the
walls 105 and 106 and 103 and 104, respectively.
[0059] Thus, from the foregoing description it should be readily
apparent that the described embodiments permit the use of storage
devices and partitioning walls that can be easily moved and
employed in any closed area without the necessity of guide rails.
This offers substantially greater versatility and a wider variety
of types of storage systems and room partitions. Of course, the
foregoing description is that of preferred embodiments of the
invention and various changes and modifications may be made without
departing from the spirit and scope of the invention, as defined by
the appended claims.
