SHELVING UNITS
Abstract
A shelving unit comprising a top, a base and at least one
intermediate shelf, all of which have vertical stubs at their
corners for attachment to uprights consisting of sheet metal
profiled sections, the stubs on the intermediate shelf projecting
both above and below it and being continuous over their whole
height on at least two of their faces, and the uprights being
notched to fit around the intermediate shelf so that the lower ends
of uprights above the intermediate shelf rest upon the upper ends
of uprights below it, so as to transmit loads straight through the
uprights to the base. The stubs may be U-sectioned, their walls
being bent inwardly at their edges, and the uprights may be of
G-section dimensioned to be a force fit over the stubs. The stubs
may be spot-welded to vertical flanges on the top, base and
intermediate shelf.

Description
BACKGROUND OF THE INVENTION
The invention relates to shelving units of the type comprising
uprights consisting of sheet metal sections, a base with stubs
projecting upwards for attachment to the uprights, and a top with
stubs projecting downwards for attachment to the shelving
uprights.
It is true that shelving units of this type can be used by
themselves. In most cases, however, several units are combined to
form a larger system. The aim of the invention is to design a
shelving unit of the type referred to so that it can be stacked up
to any required height, the forces in the uprights being conducted
straight to the base surface without any deviation.
SUMMARY
According to the invention, a shelving unit of the type described
above further comprises at least one intermediate shelf with stubs
consisting of sheet metal sections disposed at its corners and
projecting both above and below the intermediate shelf, which stubs
being continuous over their whole height on at least two adjoining
faces, the shelving uprights being notched at their ends so that
the end faces of respective uprights attached from above and below
to each stub on the intermediate shelf are in contact with one
another in the region of the continuous through faces of the
stub.
A shelving unit constructed in this manner can be used in various
ways. Thus a unit consisting of a base, four uprights and the top
of the shelving unit can be employed as a basic unit. In most
cases, however, a further unit will be stacked above the
aforementioned intermediate shelf. In this case it will not be a
top which is fitted on to the uprights attached to the base of the
shelving unit, but an intermediate shelf. Then four upright
components will again be attached to this intermediate shelf and
then either a shelving top or yet another intermediate shelf
attached to the top ends of the uprights. Even when intermediate
shelves are used the forces in the uprights are transmitted
directly to the base of the shelving because the end faces of the
uprights make direct contact with one another and so an upper
upright can be supported directly on the adjoining lower upright
without the necessity for forces to be introduced into the
intermediate shelf.
The stubs consist advantageously of U-sections, the web of the U
making contact with one side of the intermediate shelf and a flange
of the U making contact with an adjoining side of the intermediate
shelf, while the opposite flange has a notch which embraces the
intermediate shelf. Thus the continuity of the outer faces of the
stubs is obtained in a simple manner.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a perspective view of a shelving unit according to the
invention in an exploded representation;
FIG. 2 is a view, on a larger scale than FIG. 1, of a corner of the
shelving unit in the region of an intermediate shelf, corresponding
with the arrows II in FIGS. 1 and 3; and
FIG. 3 is a horizontal section along the line III--III of FIG.
2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The shelving unit represented in FIG. 1 has a base 1, four lower
upright components 2,3,4 and 5, an intermediate shelf 6, four upper
upright components 7,8,9,10 and a top 11. The base 1, the
intermediate shelf 6 and the top 11 are all rectangular and are
constructed substantially similarly as regards their flat portions.
Each of these portions has a plane shelf surface 12, vertical edge
flanges 13 and inturned flanges 14 at right angles to the vertical
edge flanges 13 (visible on the top 11 only, in FIG. 1), extending
parallel with the shelf surface 12 so that the marginal regions of
the parts 1,6 and 11 have a U-shaped cross-section. As can be seen
from FIG. 3, the inturned flanges 14 meet in a mitre formation at
the corners at 15 and are welded or soldered together at these
joints.
Provided on the longer sides of the rectangular parts 1,6 and 11
are insertion slots 16 for partitions, while there are holes 17 in
the shorter sides for the insertion of grilles for the shelving
unit. As can be seen from the shelving top 11, these holes 17 are
also provided in the inturned flanges 14.
The uprights 2,3, and 4,5 are mirror images of one another,
respectively, which means that the uprights which are situated
diagonally opposite one another, i.e., the uprights 2,5 and the
uprights 3,4 are alike. Each of the uprights consists of a
G-profile in section, as can be seen more clearly from FIG. 3. The
G-profile has wall portions 18,19,20,21 and also edge bevels 22 and
23. As shown in FIG. 1, the uprights 2 to 5 are cut out at their
ends in such a way that the walls 20, 21 are shorter than the walls
18,19 respectively. Beads 24 are provided adjacent the corner
between the wall 21 and the wall 20. A corresponding bead can also
be seen in FIG. 3. The wall 21 also has studs 25 stamped out of the
wall these studs serving for the insertion of intermediate shelves
such as the intermediate shelf 26 indicated by a broken line in
FIG. 1.
The upper uprights 7,8,9 and 10 likewise consist of G-sections. The
only difference from the lower uprights is that the uprights 7 to
10 are cut out at their top ends only and not at their bottom ends.
Four corner stubs 27,28,29 and 30 are fitted to the base 1 of the
shelving unit. The corner stubs consist of U-sections. Their manner
of fixing to the base 1 will be described with reference to the
stub 29 as an example. Like the other stubs, this stub has a web 31
and two parallel flanges 32 and 33. The web 31 and the flange 32
extend through the entire height of the stub whereas the flange 33
is shorter, by the thickness d of the base 12, than the web 31 and
the flange 32. The stub 29 is applied from outside against the
associated corner of the base 12 in such a way that the web 31 and
the flange 32 are in contact with the vertical base flanges 13,
whereas the flange 33 engages by its lower side over the shelf
surface 12. The flange 32 and the web 31 are connected to the base
flanges 13 by spot welding. The stubs 27 to 30 are slightly
contracted at their top ends. To this end notches are provided at
the corners 34 (see on stub 28) so that the tops of the individual
walls 31,32,33 can be bent over inwards, at an angle of about
30.degree. for example.
Four stubs 35,36,37 and 38 are provided on the intermediate shelf
6. Here, again, the stubs are U-sections which are applied to the
intermediate shelf in the same way as the stubs on the base 1, with
the exception that the stubs 35 to 38 project beyond the shelf 6 on
both sides, i.e., above and below it. To make this possible, a
notch 39 is provided on one flange of each stub, embracing the
intermediate shelf. The stubs 35 to 38 are provided with
contractions at both ends, of the same form as in the case of the
stubs 27 to 30 on the base 1. Each of the stubs on the intermediate
shelf has two faces 47,48 which continue straight through from top
to bottom of the stub.
Finally, the shelf top 11 has stubs 40,41,42,43 which are fitted in
the same manner as has already been described with reference to the
base 1. The difference from the base 1 is that in the case of the
base the stubs project upwards and in that of the top they project
downwards.
The manner of assembly of the shelving unit is made clear
immediately by FIG. 1. First the uprights 2 to 5 are fitted over
the stubs 27 to 30. The intermediate shelf 6 is then put on by
fitting the stubs 35 to 38 into the uprights 2 to 5, then the upper
uprights 7 to 10 are fitted over the upper ends of the stubs 35 to
38 and finally the stubs 40 to 43 of the shelf top are fitted into
the upper ends of these uprights. As can be deduced from FIG. 2,
the lower sides 44 of the upper uprights 7 to 10 rest directly upon
the upper sides 45 of the lower uprights 2 to 5, in each case, of
course, only in the region of the walls 18 and 19, the other walls
being notched. Hence the pressure of the upper uprights 7 to 10 is
transmitted directly, i.e., with no deviation, by way of the
intermediate shelf 6 to the lower uprights 2 to 5 and from there to
the base 1.
It can be seen from FIG. 3, that the free edges of the stubs are
prevented from deflecting by the G-profiles of the uprights. Here
one free edge is embraced by the bevel 22 of the G-profile, while
the other edge is prevented from deflecting between the inside of
the wall 20 and the bead 24 which is provided for this purpose.
FIG. 3 also shows spot weld points 46 by which the stubs are fixed
to the intermediate shelf 6.
The drawings do not show accessories such as side grilles which are
inserted in the holes 17 and sloping edges on the shelf flanges 14
for the attachment of clips by means of which a number of shelving
units placed side by side can be fixed together.
