According to the invention, at least one pin (35;35A,135A;35B,135B;35C;35D;35E) integral with said plaque (31;31A;31B;31C;31D;31E) and suitable for being introduced into a hole (37) of said wall (P), cooperates with said at least one fixing means (34:34A;34B,134B;34C;34D;34E,134E,234E).

Description

The present invention relates to a perfected support for the wall assembly of a cantilever piece of furniture, such as, for example, cupboards and bases for kitchens and bathrooms, cantilever furniture for bedrooms and living rooms, and the like.
As is well-known to experts in the field, supports commonly used for the wall assembly of cantilever furniture consist of plaques, more or less rectangular, but which can have numerous configurations, said plaques being fixed to the wall by fixing means, for example expansion dowels, chemical dowels, or similar fixing means which are considered as being totally equivalent.
These plaques have sections - generally raised edges or windows with respect to the wall to which they are fixed - to which the hook of the hanging bracket fixed to the piece of furniture is connected.
Supports and hanging brackets of this type are described for example in patents EP-A-11767641.1 and PCT/EP2012/001234 , of the same Applicant, to which reference should be made for any further clarifications, and which should be considered as being an integral part of the present description.
These supports are subjected to severe combined stress in both directions, vertical and horizontal, due to the weight of the contents of the wall cupboard.
This stress is transmitted from the support to the fixing dowels to the wall, and said dowels are consequently subjected to both shear and tensile stress, with the consequent risk of the yielding and falling of the cupboard.
The general objective of the present invention is to solve the above-mentioned technical problem of the known art, by providing a support equipped with means capable of adequately resisting combined shear and tensile stress transmitted from the loaded cupboard to the fixing dowels to the wall.
This objective is achieved by a support having the characteristics specified in the enclosed claim 1 and sub-claims.
The structural and functional characteristics of the invention, and its advantages with respect to the known art, will appear more evident from the following description, referring to the enclosed drawings, which illustrate embodiment examples of the same invention.
In the drawings:

figures 13 and 14 are two perspective views illustrating a fifth embodiment of a support according to the invention;
figures 15 and 16 are two raised front and side views, respectively, of the fifth embodiment of the invention;
figures 17 and 18 are two perspective views illustrating a sixth embodiment of a support according to the invention;
figures 19 and 20 are two raised front and side views, respectively, of the sixth embodiment of the invention;
figures 21 and 22 are two perspective views illustrating a seventh embodiment of a support according to the invention;
figures 23 and 24 are two raised front and side views, respectively, of the seventh embodiment of the invention.

Figures 1 and 2 of the drawings illustrate a first embodiment of the invention in which the numerical reference 30 indicates as a whole a support to which a hanging bracket device R of a wall cupboard M, as clearly illustrated and described, for example, in patents EP-A-11767641.1 and PCT/EP2012/001234 , is destined to be hooked.
Said support 30 is in the form of a metal plaque 31, having a substantially elongated rectangular form, and having a central section 32, raised or deep-drawn, for example where there is a window 33. A raised or deep-drawn section refers to a section which is suitably spaced from a wall P, or from the plane on which said plaque 31 lies.
A hook G of the hanging bracket R indicated above, is hooked to said window 33.
According to the invention, the support 30 is fixed to a wall P by the combination of fixing means, which can be of any type, for example an expansion dowel 34, and a pin 35, which are inserted in respective holes 36, 37 situated in the same wall P.
The dowel 34 and pin 35 are respectively positioned in correspondence with the upper and lower opposite ends of the plaque 31.
The dowel 34 is expanded by means of a screw 38 passing through a hole 39 of the plaque 31, whereas the pin 35 extends integrally from the plaque 31 itself.
It is evident how the combined action of the dowel 34 and the pin 35 effectively resists the forces applied to the plaque 31 in vertical and horizontal directions indicated by the arrows F1 and F2 respectively.
Figures 3 and 4 illustrate a second embodiment of the invention, substantially equivalent to the first: the only difference is that a bush 40, for example made of plastic material, which receives the pin 35, is inserted in the hole 37 of the wall P.
Figures 5-8 illustrate a third embodiment of the invention, wherein a first and second pin 35A, 135A, upper and lower respectively, cooperating with only one dowel 34A with an expansion screw 38A, extend integrally in correspondence with the free ends of a plaque 31A.
In this embodiment, the single dowel 34A is positioned below the upper pin 35A where there is a hole 39A for the passage of the expansion screw 38A.
Figures 9-12 illustrate a fourth embodiment of the invention, where there are two pins 35B, 135B and two dowels 34B, 134B, with expansion screws 38B, 138B.
As can be clearly seen from the figures, a first pin 35B is positioned in correspondence with the upper end of the plaque 31B, whereas a second pin 135B is positioned slightly below the deep-drawing 32B comprising the window 33B.
A first dowel 34B, on the other hand, is positioned below the upper pin 35B, whereas a second dowel, 134B is positioned below the lower pin 135B.
In other words, the dowel 34B is positioned between the pin 35B and the deep-drawing 32B, whereas the dowel 134B is positioned between the pin 135B and the lower free end of the plaque 31B.
Figures 13-16 illustrate a fifth embodiment of the invention, comprising a support 30C consisting of a metal plaque 31C which, instead of having an elongated rectangular form such as that of the plaques 31, 31A and 31B, illustrated in figures 1-12, has a squared rectangular form, with stiffening ribs 41C.
Said plaque 31C is fixed to the wall by the combination of four dowels 34C with expansion screws 38C, and two pins 35C.
As can be clearly seen in the figures, the four dowels 34C are positioned in correspondence with the corners of the plaque 31C, whereas the pins 35C are positioned laterally (in correspondence with the vertical sides of the plaque 31C) in an intermediate position between the dowels 34C positioned at the corners. The plaque 31C also has raised windows 33C for the connection of the hook G of the hanging bracket device R.
Figures 17-20 illustrate a sixth embodiment of the invention comprising a support 30D consisting of a squared metal plaque 31D, with a central horizontal deep-drawn section 32D, provided with windows 33D for the connection of the hooks G of the hanging bracket device R of the cupboard M.
As can be clearly seen in the figures, the plaque 31D is fixed to the wall by the combination of two pins 35D and two dowels 34D with expansion screws 38D.
According to this embodiment of the invention, the pins 35D and the dowels 34D are arranged in diagonally opposite positions, in correspondence with the corners of the plaque 31D itself.
Figures 21-24 illustrate a seventh embodiment of the invention comprising a support 30E consisting of a metal plaque 31E having a substantially triangular form, which can be fixed to the wall by means of a pin 35E and three dowels 34E, 134E, 234E, with expansion screws 38E, 138E, 238E.
Close to the dowel 34E, there is a section 32E, deep-drawn or raised, with a window 33E for the connection of the hook G of the hanging bracket device R of the cupboard M.
As can be clearly seen from the figures, the pin 35E is positioned in correspondence with the bottom vertex of the triangle, the dowels 34E, 134E are positioned in correspondence with the upper vertexes of the triangle, whereas the dowel 234E is positioned below the deep-drawn section 32E, close to the vertical side of the triangle.
It is evident how, in all seven embodiments of the invention described above, with reference to the figures, the combined action of the dowels and pins is able to ensure considerable resistance to the shear and tensile stress transmitted by the loaded cupboard to the same dowels and pins.
The objective mentioned in the preamble of the description has therefore been achieved.
The protection scope of the present invention is defined by the enclosed claims.
