Description

The present invention relates to a positioning and supporting group for the rapid assembly to the wall of a piece of furniture, cantilever extending from the wall itself.
The group according to the invention is preferably but not necessarily used for the cantilever wall assembly of a base of a piece of furniture, using so-called base-bracket devices of the visible type.
Visible base-brackets are well-known to experts in the field and, in short, consist of a device which is fixed inside the shoulder of the base. A hook extends from said device, which is suitable for being connected, for example, to the window of a plate fixed to the wall.
The position of the hook can be regulated in height (vertical) and in depth (horizontal), so as to register the position of the base on the wall, and with respect to other adjacent bases.
A base-bracket of this type is described for example in European patent application EP2303068 .
An example of a plate which can be used, in its general configuration, with said base-brackets is described, for example, in Italian patent applications MI2010A001674 of September 15, 2010 and MI2011A000590 of April 11, 2011 .
A further positioning and supporting group is known from DE 20 2009 000 241U .
An easy, rapid and safe assembly of furniture bases, using the base-bracket devices mentioned above, implies fixing the plates to the wall in a correct position, above all with a reciprocal interaxis substantially identical to that between the hooks of the base-brackets.
Even small positioning errors, in fact, make it impossible to assemble the piece of furniture, which requires re-positioning of the plates on the wall, with a considerable loss of time and therefore with significant additional costs.
This drawback mainly arises when various adjacent bases must assembled and when even small differences in height of the interaxes of the plates accumulate, making it practically impossible to assemble all of the bases without adjusting the position of the plates fixed to the wall.
For the above reasons, the fixing of plates to the wall is an extremely delicate operation, which requires the intervention of expert assemblers.
The objective of the invention is to overcome the above drawback of the known art, by providing a positioning and supporting group wherein the fixing of the plates to the wall is effected automatically at a reciprocal interaxis which is perfectly identical to that between the hooks of the base-brackets fixed inside the shoulder of the bases.
The above objective is achieved by a group having the characteristics specified in the enclosed claim 1.
The structural and functional characteristics of the invention and its advantages with respect to the known art, can be clearly understood from the following description, referring to the enclosed drawings which illustrate embodiments examples of the invention itself.
In the drawings:

figures 14 and 15 are views respectively illustrating a base of a piece of furniture equipped with a base-bracket, and a positioning and supporting group according to the invention, these figures indicating the dimensional conditions to be satisfied so that the base can be correctly assembled on said group; and
figure 16 is a detail of a possible means for fixing the group according to the invention to the wall.

The group according to the invention is indicated as a whole with G.
Figures 10 and 13 of the drawings illustrate a piece of furniture M (for example a base), which must be cantilever-hooked to a series of plates 20 fixed to a wall P (figures 9 and 12).
The hooking is effected by means of a corresponding series of base-bracket devices 21, each of which is fixed inside the shoulder 22 of the piece of furniture M.
For this purpose, the base-brackets 21 are equipped with a protruding hook 23 which is connected to a deep-drawn window 24 of the relative plate 20.
As already specified, the base-brackets 21 and plates 20, in their general configuration, can be, for example, of the type widely described and illustrated in the above-mentioned patent applications, to which reference should made for any possible further clarifications.
As is evident from figures 10-15 of the drawings, and as is well-known to experts in the field, the interaxis "A" between the windows 24 of the plates 20 and the interaxis "A'" between the hooks 22 must be the same to allow the piece of furniture M (base) to be hooked to the plates 20. Only if this condition is satisfied, can the hooks 23 be connected to the corresponding window 24, without the necessity of effecting difficult repositioning interventions of the plates 20 on the wall P.
The group and method of use of the same, according to the invention, satisfy this requirement rapidly and automatically.
With reference to figures 1-9 of the drawings, the group according to the invention is indicated, as a whole, with the letter G and is structurally composed of the characteristic combination of a bar or drawn wire 25 (made of metal or plastic material, for example) and a plurality of plates 20.
The bar 25 and plates 20 are suitable for being fixed to the wall P by means of respective fixing means 27 and 30.
Hereafter, the fixing means 27 are also called third fixing means, whereas the fixing means 30 are also called first fixing means.
The bar 25 has a plurality of holes 26 for the passage of fixing pegs 27 (third fixing means) of the bar 25 itself to the wall P.
According to the invention, between the bar 25 and the plate 20, there are also second and fourth reciprocal coupling means.
More specifically, in the bar 25 second coupling means are envisaged, consisting of a plurality of threaded holes 28, suitably interspaced, for the possible fixing on the bar 25 of the plates 20 by means of screws 29 (figures 7 and 8). The screws 29 pass through the holes 34 in the plate 20 (figure 6). The plates 20 are then fixed to the wall P by means of pegs 30 (first fixing means) passing through loops 31.
In order to ensure a rapid and precise centring of the screws 29 with the respective holes 28, the bar 25 and the plate 20 are also equipped with fourth reciprocal coupling means in the form of respective pairs 32, 33 of reference or reciprocal centring means.
More specifically, said pairs of reference or reciprocal centring means consist of a pair of holes 32 in the bar 25, and a pair of deep-drawn bushes 33 (with a reamed inlet) in the plate 20.
The pairs of bushes 33 are accurately inserted in the respective pairs of holes 32, the threaded hole 28 being situated between these holes 32 (figures 5, 5a, 6, 7 and 8).
Said pairs of reference and centring means 32, 33 also have the function of ensuring the reciprocal positioning of the plates 20 at the desired interaxis, without the necessity of fixing the same plates 20 to the bar 25.
As is clearly illustrated and explained in figures 14 and 15 of the drawings, the heights B, C, D and E between the components of each plate 20, are such as to ensure that at the moment of assembly of the piece of furniture M to the wall, the hooks 23 of the base-brackets 21 can be rapidly and automatically connected to the windows 24 of the relative plates 20.
More specifically, according to the invention, the following conditions are satisfied: A=A', wherein A=B+D+D=B+2D and wherein A=C+E+E=C+2E. Wherein A is the interaxis between the windows 24 of the plates 20. And wherein A' is the interaxis between the hooks 23 of two base-bracket devices 21 fixed to the opposite shoulders 22 of the piece of furniture M (figure 14).
The group G according to the invention, can be used, for example, following the phases illustrated in figures 7-10 of the drawings.
More specifically, the bar 25 is fixed to the wall P at the desired height and perfectly levelled (figure 7).
A plurality of pairs of plates 20 corresponding to the number of bases M to be assembled, is subsequently correctly positioned on the bar 25 (figure 8), using the pairs of holes 32 and reference bushes 33 (centering), and the same plates 20 are then firmly fixed directly to the wall P (figure 9) by means of the pegs 30, without the necessity of previously fixing them to the bar 25.
In any case, if desired, further fixing pegs 35 of the group to the wall (fifth fixing means) figure 16, can be inserted through the reamed inlet of the bushes 33.
At this point, the base M of the piece of furniture can be cantilever-assembled onto the wall P, by introducing and connecting the hooks 23 of the base-brackets 21 to the corresponding windows 24 of the plates 20, which will automatically be in position (figure 10) for the reasons described above.
Alternatively, it is possible to also proceed as illustrated in figures 11-13, as follows: first screwing the plates 20 onto the bar 25 by means of the screws 29, so as to obtain a rigid group G, and then fixing the plates 20 themselves (group G) to the wall, as illustrated in figures 11 and 12, by means of the pegs 30. The fixing of the bar 25 to the wall P by means of the pegs 27 - in this mode of use of group G - is optional.
The piece of furniture M can be subsequently assembled to the wall as illustrated in figure 13.
The objective mentioned in the preamble of the description has therefore been achieved.
The protection scope of the invention is defined by the enclosed claims.
