Description
The present invention relates to a set of metal
shelves.
Sets of metal shelves are currently widely used and are
appreciated for their strength and light weight.
The sets of metal shelves used industrially,
commercially and privately also feature a flexibility in
configuration which makes them versatile and suitable to
meet the most disparate application requirements.
The structure of the sets of metal shelves used mainly
in the industrial field substantially comprises two or more
pairs of uprights which are mutually connected by cross-members
and support stringers which in turn support the
shelves.
The uprights and the respective cross-members are
mutually coupled by means of bolts or rivets.
Although these coupling methods are per se effective,
they entail long times for the assembly and disassembly of
the set of shelves.
The assembly and disassembly or modification of
conventional sets of shelves also entail the use of specific
tools and sometimes of specialized personnel, further
increasing the costs.
A principal aim of the present invention is to provide
a set of metal shelves in which the connections,
particularly between the uprights and the respective cross-members,
occur without the aid of bolts or rivets.
Within the scope of this aim, an object of the present
invention is to provide a connection between the upright and
the respective cross-members which is stable, reliable over
time and has good mechanical characteristics as regards
structural strength.
Another object of the present invention is to provide a
set of shelves for which the assembly and disassembly
operations are quick and easy to perform and therefore can
be carried out by personnel having no particular
specialization.
Another object of the present invention is to provide a
set of shelves having competitive costs with respect to
those of conventional sets of shelves.
Another object of the present invention is to provide a
set of shelves which can be manufactured with conventional
technologies and whose components can be easily mass-manufactured.
This aim, these objects, and others which will become
apparent hereinafter are achieved by a set of metal shelves
comprising at least two pairs of uprights which are mutually
connected by cross-members and support stringers which in
turn support shelves or equivalent resting means, said set
of shelves being characterized in that said cross-members
are connected to the corresponding uprights by snug
interlocking in corresponding through slots formed in said
uprights, two consecutive cross-members cooperating for each
interlock, the respective ends of said cross-members which
are engaged in the interlock being shaped so as to form
engagements which have substantially mutually perpendicular
planes of arrangement.
Further characteristics and advantages of the present
invention will become apparent from the following detailed
description of an embodiment and of variations thereof,
illustrated only by way of non-limitative example in the
accompanying drawings, wherein:
With particular reference to figures 1 to 10, a set of
metal shelves, structured according to the invention, is
generally designated by the reference numeral 10.
The set of shelves 10, in this case, comprises two
pairs of uprights 11 which are mutually connected by cross-members,
described hereinafter, and support stringers 12
which in turn support shelves 13.
Said cross-members are connected to the corresponding
uprights 11 by simple interlocking in corresponding slots 14
formed in series arranged vertically on each one of the
uprights 11.
In this embodiment, a first cross-member 15, arranged
at an angle upon assembly, and a second cross-member 16,
arranged horizontally upon assembly, cooperate by mutual
interference for each interlock.
The cross-members 15 and 16 engaged in a same interlock
are therefore consecutive; in one of said cross-members, the
end which is engaged in the interlock is shaped so as to
form an engagement which has a substantially vertical plane
of arrangement, whilst in the other cross-member, the end
which is engaged in the interlock is shaped so as to form an
engagement which has a substantially horizontal arrangement.
More specifically, each one of the first cross-members
15 has a first end 17 which is flattened and shaped so as to
form two lugs 18 with an L-shaped profile which lies, upon
assembly, on a horizontal plane and is suitable to ensure
horizontal engagement.
Each one of the first cross-members 15 furthermore has
a second flattened end 19 which lies opposite to the first
end 17 and in this case is shaped so as to form an L-shaped
lug 20, whose profile lies on a vertical plane upon
assembly, and a guiding flap 21.
Each one of the second cross-members 16 has a first
flattened end 22 which is shaped so as to form two lugs 23
which are shaped so that they have an L-shaped profile which
lies on a horizontal plane upon assembly and is suitable to
produce engagement on said plane.
Furthermore, each one of the second cross-members 16
has a second flattened end 24 which is shaped so as to form
an L-shaped lug 25, whose profile lies on a vertical plane
upon assembly and is suitable to provide an engagement on
said plane, and a guiding lug 26.
Upon assembly, therefore, interlocking in the
corresponding slots 14 occurs alternately and respectively
between a first end 17 of a first cross-member 15 and a
second end 24 of a second cross-member 16, and between a
second end 19 of a first cross-member 15 and a first end 22
of a second cross-member 16.
In this case, both the first cross-members 15 and the
second cross-members 16 are tubular and the flattened and
shaped ends are provided by cropping and plastic deformation
so as to form the corresponding lugs.
The set of shelves 10 further comprises L-shaped shims
27 which are suitable to enter a slot 14 if there is
provided a first cross-member 15 or a second cross-member 16
without the subsequent cross-member.
The stability of the interlocks of the set of shelves
10 is increased further by the provision, on each one of the
uprights 11, of a longitudinally arranged seat 28 on the
bottom whereof the slots 14 are formed.
More specifically, in this case each one of the
uprights 11 is shaped so as to form two longitudinally-arranged
wings 29 which are mutually parallel and suitable
to form the seat 28.
Figure 11 illustrates a different embodiment of the
seat 28, which in this case is formed in cooperation by two
wings 30 with a cavity 31.
With particular reference to figure 12, another
embodiment of the seat 28 is shown which provides, at each
one of the uprights 11, for the formation of a
longitudinally-arranged cavity 32, on the bottom whereof the
slots 14 are formed.
Finally, figure 13 illustrates another embodiment, in
which a cavity 33 is provided which is equivalent to the
previous cavity 32 but is obtained by bending the sheet
metal several times and therefore has structurally stronger
walls.
In practice, it has been observed that the present
invention achieves the intended aim and objects.
In particular, it should be noted that the set of
shelves according to the present invention is entirely free
from connecting elements such as bolts or rivets.
Moreover, the assembly of the set of shelves according
to the present invention is very quick and simple and can be
performed even by nonspecialized personnel.
The mutual positioning of the cross-members is in fact
substantially guided by the structure of the cross-members
and by particular provisions in the shaping of the uprights.
It should also be noted that the set of shelves
according to the present invention is, as a whole, highly
flexible and suitable to meet the most disparate application
requirements.
However, its flexibility and easy assembly, as well as
the elimination of the above-mentioned connections by means
of bolts or rivets, have no negative effect on the good
overall structural strength.
The present invention is susceptible of numerous
modifications and variations, all of which are within the
scope of the inventive concept; all the details may also be
replaced with other technically equivalent elements.
The materials as well as the dimensions may be any
according to requirements.
Where technical features mentioned in any claim are
followed by reference signs, those reference signs have been
included for the sole purpose of increasing the
intelligibility of the claims and accordingly, such
reference signs do not have any limiting effect on the
interpretation of each element identified by way of example
by such reference signs.
