Description

FIELD OF THE INVENTION

The present invention relates to a system for anchoring a wall-cupboard element to a wall, i.e. furniture cantilevered from a wall at a certain height from the floor.
More specifically, the anchoring system according to the present invention is specifically designed for anchoring elements commonly called "bases" to a wall, and is therefore part of those devices that are known in the field as "base brackets".
Elements of furniture cantilevered to the wall are commonly called "wall units" in the field, when they are finished furniture, that is, equipped with a lower base element, an upper top, side shoulders, and generally a back wall also called lining, whereas they are commonly called "bases" when they are destined for holding a supporting or work surface, such as a kitchen worktop, or a washbasin in the case of bathroom furniture, or an accessory such as the burners of a gas cooker or an induction plate, and so forth.
Whereas base-supporting devices or hanging brackets, depending on their intended use, are known in the field in numerous variants, the present invention relates to a system specifically designed for use as a base bracket which also performs a structural function for the base module, as already specified, generally supplied without the upper top and without the back wall or lining.

STATE OF THE ART

Hanging-bracket or base-bracket supporting devices are described for example in patents EP0033179 and EP2303068 .
Base-bracket devices with a reduced thickness and depth are therefore known in the field, so that they do not hinder the housing of drawer guides or other devices that must be housed in the base.
These base-bracket devices of the known type, however, do not solve various drawbacks that limit their use.
The base-bracket devices of the type object of the present invention are in fact fixed to the shoulder of the furniture element, but in the case of furniture elements intended to be used as a base, on which a work top or the surface of a washbasin or similar upper elements will only be mounted subsequently, the base furniture is supplied by the manufacturer without the upper top and without the back wall or lining, and consequently the bottom element and shoulders of the piece of furniture, already assembled together, create storage and transportation problems, requiring specific packaging, and also particular attention on the part of the operators when fixing the piece of furniture to the wall as the base element in fact is not a structurally complete element.
Again, a further disadvantage lies in the fact that the base furniture destined for supporting a surface or utility generally requires that during the assembly phase of the furniture, supporting means also be provided for said surface or utility, which must also be supplied and mounted in the assembly and installation phase of the furniture to the wall.
This obviously creates greater difficulty and longer times for mounting the base furniture during the assembly and installation phase of the furniture itself, but also entails leaving the task of assembling the base furniture to the operator, thus increasing the risk of error in the assembly.

SUMMARY OF THE INVENTION

In the light of the above, the undertaking of the present invention is to solve the drawbacks that affect the base-bracket devices of the known type by providing a base-bracket system that is also capable of exerting a structural function for the base furniture itself, thus allowing the pre-assembly of the base and transportation of the base already assembled.
Furthermore, the undertaking of the present invention is to provide a base-bracket system that not only provides a system for anchoring a base to the wall, but also exerts a structural function for the components of the base itself.
Within this undertaking, the objective of the present invention is to provide a base-bracket system that also exerts a structural function in supporting the worktop or accessory that is mounted above the base.
Last but not least, the objective of the present invention is to provide a base-bracket system that has a pleasant aesthetic impact and is versatile in the installation, at the same time being able to satisfy various aesthetic needs required by the furniture manufacturer.
The above-mentioned undertaking, as also the objectives specified and others that will appear in greater detail hereunder, are achieved by a system for anchoring a wall-cupboard element to a wall according to the enclosed claim 1.
Further characteristics of the preferred embodiments of the anchoring system according to the present invention described in the present application are the subject of the dependent claims.

DETAILED DESCRIPTION OF THE INVENTION

With particular reference to the attached figures, a system for anchoring a wall-cupboard element to a wall is described hereunder, i.e. furniture cantilevered from a wall at a certain height from the floor, and more specifically for anchoring elements commonly called "bases" to the wall, destined for holding a supporting or work surface, such as a kitchen worktop, or a washbasin in the case of bathroom furniture, or an accessory such as the burners of a gas cooker or an induction plate, and so forth.
The anchoring system 1, 1', 1'' for anchoring a wall cupboard to the wall, and in particular a base, according to the present invention, will now be described with reference to the attached figures which schematically show a wall unit called base 100, i.e. a piece of furniture comprising two opposing shoulders 101 and a lower element 102 which connects said shoulders 101 by means of joining systems of the known type, not shown.
The shoulders 101 are connected at their lower end 101a to said lower element 102, or base of the furniture, and are free in correspondence with their opposite upper end 101b.
The elements called bases are in fact supplied without the upper element, also called top, as they are intended to support a worktop or an accessory in the upper part, for example in the case of kitchen furniture, or a washbasin, for example in the case of bathroom furniture, or tops made of glass or other materials for example in the case of living-room furniture.
As is known, the bases are also generally supplied without a back wall or lining, as parts of the plumbing system are generally housed inside the base, in the case of under-sink furniture for example, or connections with gas pipes or electrical connections in the case of kitchen cabinets that support the worktop, burners or induction plates or the like. As the bases are generally closed at the front by doors or are designed for housing drawers, the furniture maker generally does not provide for closing the bottom of the base with a lining.
In the case of bases without an upper element or top, the need is therefore felt for providing an anchoring system for anchoring a base to the wall that also exerts a structural function, completing the structure of the base furniture, making its storage, packaging, transportation and assembly simpler and safer.
Furthermore, the need is also felt in the field for being able to increase the stability and capacity of the base to support loads, in particular the weight of the worktop or in any case of the element that the base will have to support, offering for its support not only the surface provided by the section of the shoulders of the base furniture itself, but also a larger surface.
The anchoring system 1, 1', 1'' according to the present invention advantageously comprises a pair of supporting devices 10 of a known type as designed and marketed by the same applicant, of the type comprising a plate-like body 10' configured for being connected to the inner face of a shoulder 101 in correspondence with its free upper end 101b.
The supporting device 10 also comprises an arm 14 terminating with a hook 14a which extends from the device itself for attachment to supporting means 60 constrained to the wall.
According to a preferred embodiment illustrated by way of non-limiting example in the attached figures, mechanisms for adjusting the depth 15, i.e. the horizontal position of the arm 14 and of the hook 14a with respect to the plate-like body 10', can advantageously be associated with said supporting arm 14, and mechanisms for adjusting the height 16 of said hook, i.e. the vertical position of the arm 14 and of the hook 14a with respect to the plate-like body 10'. The anchoring system according to the present invention also comprises at least one connection bar 40, 40', 40" which connects said supporting devices 10 to each other.
With particular reference therefore to the attached figures, once the anchoring system 1, 1', 1'' according to the present invention has been assembled at the base, the connection bar 40, 40', 40'' is arranged substantially horizontal, i.e. substantially parallel to the base element 102, and exerts a structural function for supporting the opposite shoulders 101 and completing the structure of the base element.
For this purpose, connection means 11a, 11b, 24a, 24b, 26a, 26b, 30, 30', 38, 39 which can have different configurations as can be seen with reference to the attached figures which illustrate different embodiments of the present invention, are provided for connecting the bar 40, 40', 40'' to said supporting devices 10.
Advantageously, said bar 40, 40', 40'' comprises, in correspondence with its upper longitudinal edge, at least one housing seat 41, 41', 41'' in which an insert 50 is housed, made of plastic material, such as ABS, or similar material, even non-plastic as long as it is elastic, i.e. having a certain capacity to behave elastically when subjected to stress due to the application of external forces.
Said insert 50 is therefore referred to herein as an elastic insert, it is understood however that as it is preferably produced by extrusion, suitable materials are plastics, in particular soft plastics, polymeric materials such as for example polyethylene, and silicone materials.
Said insert advantageously has an upper surface 51 suitable for forming a supporting surface for said top, element or accessory positioned for the upper closure of the base furniture 100.
Furthermore, the anchoring system 1, 1', 1'' according to the present invention preferably provides that the bar 40, 40', 40'' has a reduced thickness S with respect to the length L and that within said thickness S, in correspondence with its side edges 40c, 40d, 40c', 40d', 40c'', 40d'', orthogonal to the upper and lower longitudinal edges, one or more housing seats 42a, 42b, 42', 42'' are provided, facing outwardly, configured for receiving said connection means 11a, 11b, 24a, 24b, 26a, 26b, 30, 30', 38, 39 for connecting the bar 40, 40', 40'' to the supporting devices 10.
The housing seat 41, 41', 41'' suitable for receiving said elastic insert 50 advantageously extends substantially for the whole length of said connection bar 40, 40', 40", so that the upper surface 51 of said insert 50 can, with the bar 40, 40', 40'' mounted flush with the upper end 101b of the shoulders 101, offer a support for the worktop or the accessory or the washbasin top which will close the base furniture above, and it will rest on the upper surface of the shoulders 101 and on the upper surface 51 of the insert 50 supported by the connection bar 40, 40', 40''.
Said insert 50 is advantageously made of plastic material having sufficient elastic properties to offer a "soft" elastic support for the upper surface so as to dampen any vibrations that generate noise, thus muffling the sounds themselves.
A further advantage obtained thanks to the presence of the elastic insert 50 is to allow any errors or tolerances in the positioning of the height of the connection bar 40, 40', 40" with respect to the height of the upper surfaces of the shoulders 101, to be compensated.
The anchoring system according to the present invention advantageously provides that the connection bar 40, 40', 40'' has a front face 40a, 40a', 40a'' and a rear face 40b, 40b', 40b'', and has housing seats 42a, 42b, 42', 42'' for the connection means 11a, 11b, 24a, 24b, 26a, 26b, 30, 30', 38, 39 identical on both side edges 40c, 40d, 40c', 40d', 40c'', 40d'' so that it can be assembled indifferently with the front face 40a, 40a', 40a'' facing the interior of the furniture 100 and with the rear face 40b, 40b', 40b'' facing the wall to which the piece of furniture must be hooked, or viceversa with the front face 40a, 40a', 40a'' facing the wall and the rear face 40b, 40b', 40b'' facing the interior of the base furniture 100.
Thanks to this expedient, i.e. the possibility of providing a reversible bar, so that the same element can be assembled by the furniture manufacturer in one direction or the other, the commercial requirement of the same furniture manufacturer to provide its furniture with different components depending on the aesthetic impact to be obtained or the level of care of the finishings to be perceived by the end customer who is buying its products, can be satisfied.
The front face 40a, 40a', 40a'' and the rear face 40b, 40b', 40b'' of said connection bar 40, 40', 40'' will, in fact, advantageously have a different surface finish, so that the furniture manufacturer can choose which side of the bar to leave visible as it faces the interior of the base furniture 100, thus modifying not only the aesthetic impact but also the quality level of the components perceived by the end customer.
The need is in fact felt in the field for taking care of all the details of a piece of furniture, and differentiating the quality level perceived by the customer between a high-quality piece of furniture and a piece of furniture within a medium or medium-high quality range.
The furniture manufacturer requires that furniture having different price ranges be equipped with accessories that can help differentiate the various models from each other in the perception by the customer, and an element that remains visible, albeit inside the furniture, such as the connection bar, is the subject of this requirement. Thanks to the possibility of mounting the bar in one direction or the other, the furniture manufacturer is offered the possibility of differentiating its products as desired, at the same time reducing the costs and the need for allocating space in the warehouse to have two connection bars available with two different surface finishings.
For this purpose, the front face 40a, 40a', 40a'' of the bar may advantageously have for example a ribbed surface, i.e., comprising a plurality of raised parallel longitudinal lines which give the surface itself a ribbed effect, whereas the rear face 40b, 40b', 40b'' may have, for example, a completely smooth surface.
Again, preferably and in order to reduce the weight of the bar, this can have a thickness S that is thin with respect to the length L, and it can be made of aluminum or similar material suitable for producing a hollow box-like structure, light but resistant to loads.
As already mentioned, the anchoring system 1, 1', 1'' according to the present invention can comprise different connection means 11a, 11b, 24a, 24b, 26a, 26b, 30, 30', 38, 39 to effect the connection of the bar 40, 40', 40'' to the supporting devices 10.
With particular reference to figures 1 to 6, a first preferred embodiment of the anchoring system 1 according to the present invention will now be illustrated, wherein the connection means for connecting the bar 40 to the supporting devices 10 comprise one or more pins, preferably a pair of pins 11a, 11b, associated with the plate-like body 10' of each of said supporting devices 10, each of said pins 11a, 11b being suitable for being inserted into a respective substantially cylindrical housing seat 42a, 42b formed within the thickness S of the connection bar 40, in correspondence with the side edges 40c, 40d of said bar 40.
As can be seen in particular in figures 3 and 4, a first of said seats 42a advantageously extends along the longitudinal direction of said bar 40 in the proximity of the upper longitudinal edge of the same, and a second of said seats 42b again extends along the longitudinal direction in the proximity of the lower longitudinal edge of the same.
Furthermore, a first cylindrical hole 43a having an axis substantially orthogonal to the longitudinal axis of said seats 42a, 42b is advantageously provided in correspondence with the upper longitudinal edge of said bar 40, and a second cylindrical hole 43b also having an axis substantially orthogonal to the longitudinal axis of said seats 42a, 42b is advantageously provided in correspondence with the lower longitudinal edge of said bar 40, so that a respective cylindrical bush 24a, 24b is housed within each of said first hole 43a and second hole 43b.
Each of said cylindrical bushes 24a, 24b in turn comprises a transversal pass-through hole 25a, 25b suitable for receiving one of said pins 11a, 11b which, in turn, each comprise, in correspondence with their portion suitable for being inserted into said transverse hole 25a, 25b of said bush 24a, 24b when the device is assembled, a further pass-through hole 12a, 12b suitable for receiving a grub screw 26a, 26b which is suitable for preventing any movement of the pin 11a, 11b with respect to the respective bush 24a, 24b.
In this way, the system 1 according to the present invention in accordance with this first preferred embodiment ensures the stable blocking of the bar 40 to the plate-like bodies 10' of the supporting devices 10.
Among the advantages of this first embodiment of the anchoring system 1 according to the present invention, the following can be indicated: the system allows the prior assembly of the base-bracket supporting devices 10 to the shoulders 101 of the base; no further interfaces are required between the extruded bar 40 and the supporting devices 10.
Among the disadvantages of this embodiment, however, it must be pointed out that the bar 40 in this case requires a complex processing which makes it difficult to supply the bar in standard sizes so that it is therefore the furniture manufacturer who cuts it according to the dimensions of the base furniture 100.
With particular reference to figures 7 to 18, a second, figures 7 to 12, and a third, figures 13 to 18, preferred embodiment of the anchoring system 1', 1'' according to the present invention, will now be illustrated, wherein the connection means for connecting said bar 40', 40'' to the supporting devices 10 comprise a pair of connection elements 30, 30' advantageously having a box-like shape and each comprising a plurality of housing holes for the same number of means 38, 39 for fixing the connection element 30, 30' to said bar 40', 40'' (thanks to the fixing means 39) and on the other hand to the plate-like body 10' of the supporting device 10 (thanks to the fixing means 38).
Each of said box-like connection elements 30, 30' comprises, in correspondence with its upper edge, a seat 32 suitable, when the element is assembled, for being arranged as an extension of the seat 41', 41'' for receiving the insert 50 made of elastic material which is provided in correspondence with the upper longitudinal edge of the connection bar 40', 40".
Even more preferably, according to the third preferred embodiment of the anchoring system 1'' in accordance with the present invention shown by way of example in figures 13 to 18, each of said box-like connection elements 30' is equipped with one or more protruding fins 31 configured for being inserted into a housing seat 44 provided within the thickness S of the bar 40'' in correspondence with the side edges 40''c, 40''d of the bar 40 itself.
According to what is illustrated for example in figures 14, 15 and 17, there are preferably two fins 31, configured for being inserted into the box-like body of the bar 40'' without the need for providing seats having particularly complex shapes.
In both embodiments which provide for the use of said box-like connection elements 30, 30', the fixing means 38, 39 for connecting the connection elements 30, 30' to the bar 40', 40'' on one side, and the plate-like body 10' of the supporting devices 10 on the other, advantageously comprise screws 38, 39.
More specifically, with reference to figures 7 to 12 and 14, 15, 16 and 18, first screws 39 connect said connection elements 30, 30' to the respective bar 40', 40'' by being inserted into pass-through holes 39a specifically provided on said connection elements 30, 30', whereas second screws 38 are advantageously provided for connecting said connection elements 30, 30' to the plate-like bodies 10' of said supporting devices 10.
The second embodiment of the anchoring system 1' according to the present invention has the advantage, similarly to what is described for the first embodiment of the system 1, of allowing the pre-assembly of the supporting devices or base brackets 10 to the shoulders 101 of the base 100 so that these are assembled for example in the factory and the base module 100 transported with the supporting devices 10 already assembled, the connection bar 40' also in this case being able to be assembled at a later time, during the installation of the furniture.
This second embodiment has the advantage, thanks to the configuration of the connection elements 30 and the connection means comprising first screws 39 and second screws 38, of allowing the bar 40' to be assembled to the base even with a partially assembled base, i.e. even when the shoulders 101 have already been assembled to the base element 102.
Furthermore, thanks to the simplicity of the geometry of the connection bar 40', it can be cut to size by the furniture manufacturer, and can therefore be produced and stored in a reduced number of pre-established sizes and then adapted by the furniture manufacturer.
The anchoring system 1'' according to the third embodiment of the present invention, illustrated as already mentioned in figures 13 to 18, provides that the anchoring devices 10 or base brackets be previously fixed to the bar 40'' so as to have a system comprising the anchoring devices 10 and the base 40'' already fixed together, so as to then connect the whole system to the shoulders 101 of the furniture.
In this configuration, however, the anchoring devices 10 can only be screwed to the shoulders 101 of the base furniture 100, and for this purpose the connection screws 18 for connecting the anchoring devices 10 to the shoulders 101 are illustrated, as it would be unthinkable to consider it possible to assemble the piece of furniture and at the same time press-insert the base brackets 10 into the holes produced in the shoulders 101, as is the case on the other hand with the variants of the other embodiments described so far.
The present invention has been described, for illustrative but non-limiting purposes, with reference to various preferred embodiments; it should be understood however that variations and/or modifications can be applied by a skilled person in the field without thereby departing from the relative protection scope, as defined in the enclosed claims.
