[0001] The present patent application for industrial invention relates to a modular system
for equipped walls.
[0002] As it is known, "equipped walls" are walls designed to support shelves, which can
be covered with wooden or similar panels.
[0003] Metal boxed bars are traditionally used to obtain similar equipped walls, being mounted
in vertical position to support both the horizontal shelves and the vertical panels
that are used to cover the masonry wall.
[0004] Said boxed bars are provided along the entire height of the lateral sides with grooves
designed to exactly receive the vertical border of an adjacent panel or, vice versa,
ribs designed to be exactly received inside corresponding grooves obtained on the
vertical border of the adjacent panel.
[0005] In order to support said horizontal shelves, each boxed bar is frontally provided
for the entire height with a rectilinear groove that can be accessed from the front
opening, which can be defined as "space".
[0006] In particular, the groove has a basically C-shaped cross-section, being bordered
by a pair of edges on the two sides and by an intermediate bottom wall on the back.
[0007] The bottom wall is provided, approximately for the entire height, with a regularly
spaced series of holes with horizontal axis that are designed to act as selective
fixing points for the horizontal shelf-holding arm.
[0008] Obviously, the presence of a plurality of fixing holes allows the final user of a
similar pair of boxed bars to fix the shelves at the desired height.
[0009] In spite of its large diffusion, such a technology is evidently impaired by some
significant drawbacks. The first drawback is of technical-functional type and consists
in the fact that dust and fine impurities of various type accumulate in the groove
used to fix the shelf-holding arms of each traditional boxed bar, and are very difficult
to remove in view of the small width of the "access" space.
[0010] Moreover, said traditional boxed bars are aesthetically impaired by the presence
of the aforesaid series of holes that act as selective fixing points for the horizontal
shelf-holding arms on the bottom of the vertical grooves.
[0011] So far, these two disadvantages have been remedied with rather complicated and expensive
solutions.
[0012] According to the first solution, said vertical spaces of traditional boxed bars are
provided with suitable rubber seals that are cut to size according to the position
selected by the user for the horizontal shelves fixed to the boxed bars.
[0013] This long delicate operation must be repeated every time the user of a similar series
of boxed bars wants to change the fixing height of the horizontal shelves that are
mounted in projecting position on the front of said bars.
[0014] Alternatively, another solution consists in "sealing" the vertical spaces of traditional
boxed bars with suitable brush seals that are commonly found on the market.
[0015] Such a solution is even longer and must be carried out by specialised workers, without
considering the cost for purchasing said brush seals.
[0016] The specific purpose of the present invention is to devise a modular system for equipped
walls that is able to solve all the aforementioned problems of the prior art technique.
[0017] Such a result has been achieved by giving a special innovative configuration to the
boxed bars used in said modular system.
[0018] In addition to reducing the penetration of fine dirt and covering the unaesthetic
series of fixing holes, the new configuration allows each bar to support a shelf regardless
of the fact that the bar is positioned in vertical or horizontal position.
[0019] More precisely, the peculiarity of the boxed bar of the invention consists in the
fact that, unlike traditional boxed bars, the front rectilinear space does not provide
direct access to the C-shaped grooves used to fix the horizontal shelf-holding arms.
[0020] According to the new configuration of boxed bar, the front rectilinear space gives
access to a C-shaped groove that is faced sideward with inclination angle of approximately
45°.
[0021] In view of the aforesaid inclination, the bottom of said groove (and the traditional
series of fixing holes) is no longer visible through the front space.
[0022] As mentioned above, the inclination of said groove also reduces the penetration of
dust and fine dirt. In any case, being impossible to prevent accumulation of dirt
on the bottom of the groove, it is practically impossible to see it from the front
of the bar of the invention.
[0023] Moreover, the new front configuration of the new boxed bar of the invention has required
a new innovative configuration also for the arms and brackets that are used to support
the shelves. Thereby, also these arms and brackets must be considered as integral
parts (or modules) of the system according to the present invention.
[0024] For purposes of clarity, the description of the invention continues with reference
to the enclosed drawings, which are intended for purposes of illustration only and
not in a limiting sense, wherein:
- Figure 1 is a top view of two pieces of a first embodiment of the boxed bar from the
system of the invention, with a panel mounted between them;
- Figure 2 is the same as Fig. 1, except in that it illustrates the coupling of said
boxed bars with corresponding shelf-holding arms;
- Figure 3 is the same as Figure 1, except in that it refers to a second embodiment
of the aforesaid boxed bar;
- Figure 4 illustrates a different mounting mode of the same boxed bar of Figure 3;
Figure 5 illustrates a third embodiment of the aforesaid boxed bar;
Figure 6 illustrates a fourth embodiment of the aforesaid boxed bar;
Figure 7 illustrates a fifth embodiment of the aforesaid boxed bar;
- Figure 8 is an axonometric view of Fig. 2, wherein the two shelf-holding arms are
illustrated during insertion for fixing purposes.
[0025] Referring to Figs. 1, 2 and 8, the first module of the system according to the present
invention consists in a metal boxed bar (1) that is open on the back and comprises
a front wall (11) and two lateral walls (12).
[0026] In particular, said figure illustrates two pieces of the aforesaid bar (1) with a
panel (P) mounted between them to close the masonry wall vertically.
[0027] To that end, each bar (1) is provided on the lateral walls (12) with suitable means
of known type to guarantee exact support and firm coupling of the panel (P), possibly
with the use of suitable fixing screws.
[0028] According to the bar illustrated in fig. 1, the means provided on each bar (1) to
favour the support and coupling of the panel (P) consist in a pair of back boxed sections
(20) integrated on the lateral walls (12) and provided with a basically C-shaped cross-section
with concavity facing the front of the bar (1).
[0029] Once the panels (P) provided on the right and left side of the bar (1) are arranged
against the lateral walls (12) of the bar (1), the back surfaces of the panels (P)
are engaged with the boxed sections (20) in such a position that allows for stable
fixing with suitable connection strips (L).
[0030] It must be noted that said connection strips (L) could be applied on the back of
the corresponding panel (P), or obtained "in one piece" in the structure of the panel
by milling.
[0031] A notch (13) or "space" is traditionally obtained on the front wall (11) of such
a bar (1).
[0032] The space (13) gives access to a niche (14) joined with a basically C-shaped groove
provided with a regularly spaced series of holes (16) on the bottom wall (15a).
[0033] The peculiarity of the groove (15) consists in the inclination of about 45° with
respect to the front space (13) that gives access to said groove (15) (or, more precisely,
with respect to the front wall (11) on which the space is obtained).
[0034] Referring to fig. 1, it must be noted that, because of such a solution, an observer
positioned in front of the bar (1) is only able to see a section of the continuous
wall that borders the longitudinal niche (14) through the space (13).
[0035] From the same visual perspective, the observer is not able to see the groove (15)
and, most of all, the unaesthetic regularly spaced series of holes (16) obtained on
the bottom wall (15a) of the groove (15).
[0036] Moreover, this solution gives an aesthetically uniform aspect to the front wall (11)
of the bar (1), in case the user wants to give it a special surface finish (such as
concave or raised).
[0037] In fact, in case of a traditional bar, the surface finish of the front wall, on the
right and left side of the space, would lack visual continuity due to the visible
presence of the series of holes obtained on the bottom of the groove.
[0038] In the bar of the invention (1), the surface finish of the front wall (11), on the
right and left side of the space (13), can be given perfect continuity, being it possible
to obtain said finish also in the internal wall of the niche (14), in the area that
is directly seen through the space (13).
[0039] Referring to fig. 1, it must be noted that the "inclined" groove (15), together with
the corresponding series of holes (16), is commonly the means for engaging and selectively
fixing the back end (21) of a horizontal shelf-holding arm (21 a).
[0040] Evidently, the need to obtain perfect coupling between the back end (21) of the arm
(21 a) and the housing and fixing groove (15) requires the back end (21) to be given
approximately 45° inclination with respect to the arm (21 a), which is perfectly compatible
with the inclination given to the groove (15) with respect to the front space (13).
[0041] Attention is drawn on the fact that, referring to fig. 1, the two pieces of bar (1)
are given a symmetrical direction, meaning that the first piece is provided with a
rightward groove (15) and the second piece is provided with a leftward groove (15),
being two pieces of the same bar (1) mounted in opposite mode.
[0042] In view of the above, the grooves (15) of the two adjacent bars (1) are faced one
against the other, according to a configuration that requires using shelf-holding
arms (21 a) provided with symmetrically opposite inclined ends (21).
[0043] Nothing prevents using two pieces of the same bar (1) with grooves (15) in the same
direction to support a panel (P). Obviously, in such a case, the same lateral inclination
must be given to the ends of the corresponding shelf-holding arms (21 a) (as illustrated
in fig. 2).
[0044] Referring to fig. 3, the same bar can be obtained according to a first alternative
embodiment (10) that differs from the one illustrated in fig. 2 in that it is provided
with different lateral means to support and fix the aforesaid panels (P).
[0045] In such a case, longitudinal ribs (22) protrude centrally from the lateral walls
(12) of the bar (1), which are adapted to be exactly engaged inside corresponding
grooves (S) obtained on the border of the panel (P), when the panel (P) is arranged
against the corresponding lateral wall (12) of the bar (10).
[0046] Fig. 4 illustrates the mounting modes of the bar (10) in horizontal position (that
is to say in intermediate position between two panels (P) overlapped in "edgeways"),
while maintaining the capability to support a shelf (R).
[0047] Such a result can be obtained by using another component of the modular system of
the present invention, which consists in a special bracket (30) adapted to be mounted
on the internal longitudinal border of a shelf (R).
[0048] According to a cross-sectional view, the bracket (30) comprises a first vertical
section (30a) with basically identical height as the thickness of the shelf (R), against
which the longitudinal border of the shelf (R) must be exactly engaged and fixed.
[0049] The first vertical section (30a) of the bracket (30) is connected with a second shorter
vertical section (30c) by means of a backwards facing short horizontal section (30b).
[0050] Fig. 4 illustrates the mounting of the bracket (30) with respect to the bar (10)
in horizontal position.
[0051] In particular, the upper section (30c) of the bracket (30) is inserted and engaged
inside the space (13) of the bar (10) from down upwards.
[0052] In view of the above, the horizontal intermediate section (30b) of the bracket (30)
rests on a horizontal stop (13a) in lower position with respect to the space (13),
whereas the upper vertical section (30c) is fitted on the back of the section (13b)
of the front wall (11) that is situated above the space (13).
[0053] Fig. 5 illustrates an alternative embodiment (1A) of the bar (1) of fig. 1.
[0054] The bar (1A) is
characterised in that it is not provided with the niche (14) on the back of the space (13).
[0055] In such a case, the space (13) is the opening of the inclined groove (15).
[0056] Likewise, fig. 6 illustrates an alternative embodiment (10A) of the bar (10) of fig.
3.
[0057] Also in this case, while maintaining all the other structural features, the bar (10A)
is
characterised in that the space (13) is the opening of the inclined groove (15).
[0058] Fig. 7 illustrates an additional embodiment (1 B) of the bar (1) of fig. 1, whose
peculiarity consists of the fact that it is provided with a side-by-side parallel
pair of inclined grooves (15).
[0059] Obviously, the embodiment (1 B) of the bar of the invention must be considered compatible
with a shelf-holding arm (21 a) provided with a side-by-side parallel pair of inclined
ends (21), in such a way that they can be exactly inserted in the two aforesaid grooves
(15) and fitted to the corresponding holes (16).
[0060] Attention is drawn on Fig. 8 to point out that the boxed bar can also be obtained
in a version adapted to act as "end module" for the equipped wall.
[0061] To that end, the bar (1 C) illustrated on the left side of said Fig. 8 differs from
the bar shown on the right side in that, starting from the external lateral wall (12),
it is provided with a boxed section (20a) with basically L-shaped cross-section with
backwards concavity.
[0062] Obviously, in such a case, the wing of the section (20a) with higher width is adapted
to act as end module of the entire equipped wall.
[0063] It is understood that the L-shaped ending section (20a) can also be provided in embodiments
of the bar of the invention other than the one that is expressly illustrated in Fig.
8.
[0064] Likewise, nothing prevents making the bars according to the different embodiments,
without the lateral means (20, 22) used to fix and support adjacent panels.
[0065] In such a case, bars of this type would only be adapted to support protruding shelves
frontally, without giving continuity to a series of panels.
