TECHNICAL FIELD OF THE INVENTION
This invention relates to storage racks.
BACKGROUND
[0001] Known forms of storage racks are often manufactured wholly or principally from metal,
so that they are very strong. Such racks may be used to carry large numbers of components
in motor vehicles, as static racks for use in factories and storerooms for example,
and mobile racks mounted on wheels or castors.
[0002] The present invention seeks to provide a new and inventive form of storage rack.
SUMMARY OF THE INVENTION
[0003] The present invention proposes a storage rack comprising:
- a set of plastics boxes which are formed with passages extending substantially vertically
therethrough;
- at least two generally planar units disposed one above another with said boxes positioned
therebetween; and
- a set of posts which connect said planar units and which are inserted through the
passages in the boxes.
[0004] It is not necessary for the posts to pass through all of the passages, or even all
of the boxes, although they are preferably inserted through the outermost passages.
The remaining passages may be provided with short locating pegs which enter the adjacent
upper and lower ends of aligned passages.

DETAILED DESCRIPTION OF THE DRAWINGS
[0006] Referring firstly to Fig. 1, the storage rack comprises an array of moulded plastics
storage boxes 1 (sometimes referred to as trays) which in the present example are
arranged in four adjacent stacks of four (i.e. four rows and four columns). As will
become apparent however, the number of boxes in the rack can vary. The boxes 1 are
supported on a generally planar base unit 2 and they, in turn, support a planar top
unit 3 positioned vertically above the base 2.
[0007] Once of the storage boxes is shown in Fig. 2. It will be noted that the box is of
a kind which is already used for general storage purposes. The box comprises a bottom
wall 10, a rear wall 11, two side walls 12 and 13, and a front wall 14. The top of
the box is open as shown, but when the boxes are stacked the interior can still be
accessed via an access window 15 formed in the front wall 14. If desired, the window
may be provided with a hinged or sliding cover (not shown). It will further be noted
that the four corners of the box 1 are provided with vertical through-passages 16
which open at the top and bottom of the box. As will be explained more fully below,
these passages are utilised in the present invention for securing the boxes together
to form a solid, lightweight structure.
[0008] In the present example, the base 2 and top unit 3 are identical, both being injection
moulded from plastics. The base unit 2 is shown in Fig. 3, and comprises a bottom
wall 20 surrounded by a shallow upstanding side wall 21. It will be noted that, at
intervals, the side wall is provided with vertically extending external recesses 22
to allow unrestricted access to the windows 15 when the unit is mounted on top of
the boxes 1. In between the recesses 22 the side wall 21 is formed with vertically
extending through-passages 24 which correspond in position to the passages 16 (see
below). The side wall 21 is joined to the bottom wall 20 by internal strengthening
webs 25. In addition, the base contains fixing platforms 26 and 27 which provide fixing
holes through which the base can be bolted down to a floor, including the floor of
a vehicle.
[0009] Referring now to Fig. 4, four tubular metal fixing posts 30 are inserted in the four
outermost passages 24 at the four corners of the base unit 2, within which they are
secured by grub screws or the like (not shown). The posts are inserted through the
corresponding holes 16 of the opposite end stacks of storage boxes 1, following which
a similar unit 3 is secured to the tops of the posts (Fig. 1), again using grub screws
or like fixings. The top and base units 3 and 2, together with the posts 30, thus
provide a rigid yet lightweight skeleton for the storage boxes. Although a post 30
could be inserted through each set of aligned passages 16, 24 this is not generally
necessary. The boxes can be located at intermediate positions by lightweight short
plastics pegs 32 (Fig. 4) which are inserted into the aligned top and bottom ends
of each pair of passages. The pegs may have an integral annular flange 33 which is
located between the two boxes acting as a spacer, and in order to ensure corresponding
spacing of the boxes in the region of the posts 30, circular spacers 34 may be threaded
onto the posts between each pair of boxes.
[0010] The size of the rack can of course vary according to the number of rows and columns
of boxes. A small rack such as that illustrated in Fig. 1 may be freestanding, but
in the case of taller racks the base unit 2 can be bolted down to a floor to ensure
stability. A smaller rack could also have wheels or castors secured to the base 2
to construct a strong but lightweight mobile rack. The rack can be installed in a
motor vehicle with the base 2 bolted down to the floor of the vehicle so that the
rack is extremely strong and will not shift even in the event of a substantial impact.
The rack system can easily be adapted to fit into a confined space such as a motor
vehicle, and various additional configurations are illustrated in Fig.s 5 to 7. It
will be noted that some of the boxes 1 can be omitted if desired, to form storage
voids 30 as in Fig. 6. Shorter or longer units 2, 3 can be provided corresponding
to an integral number of boxes, to accommodate wheel arches for example. In addition
intermediate units 40, similar to the base units 2, can be provided between the top
and bottom units, again secured to the posts 30. Where there is insufficient space
to accommodate a single-width base unit an intermediate unit 40 can additionally be
supported by a pair of short legs 50 as shown in Fig.s 7 and 8. The leg may again
be fixed into one of the passages 24 and is provided with a bottom flange 51 for fastening
down to a floor.
[0011] Referring back to Fig. 3, it will be noted that the units 2 and 3 contain internal
transversely extending slots 29. When the unit is mounted on the top of a relatively
low rack it can be used as an additional storage tray. Transverse dividers can be
inserted into the slots 29 to form shallow storage compartments for small components.
Alternatively the top unit 3 can be mounted upside down to provide a flat top.
[0012] If desired, a number of racks can be linked to form longer storage racks which are
a multiple of the units 2, 3 in length. One way of achieving this is to replace the
spacers 34(Fig. 3) with link plates 60 of the kind illustrated in Fig. 9. The plates
are of elongate shape and include a spaced pair of holes 61 and 62 at opposite ends,
which receive the posts 30 of adjacent racks. Generally at least four such plates
60 will be required to join each pair of racks.
[0013] It will be appreciated that the features disclosed herein may be present in any feasible
combination. Whilst the above description lays emphasis on those areas which, in combination,
are believed to be new, protection is claimed for any inventive combination of the
