The present invention relates to a visible wall cupboard holder group, adjustable for anchoring a cupboard to the wall.

In particular, the wall cupboard holder in question is defined as being visible as it is destined for being assembled inside a wall cupboard.

Wall cupboard holders in which a hook is situated at the free end of an arm which extends externally from a box-shaped body made of plastic material, are well known to experts in the field.

Said box-shaped body contains a mechanism for regulating the positions in depth and height of the hook, which is to be hooked to a wall support, a shaped metallic section, peg or other similar item.

The wall cupboard holder thus structured is fixed to the shoulder of the cupboard by means of self-threading screws, or pressure-yielding plugs made of a plastic ma- terial, with a saw-toothed profile, in correspondence with the upper edges of the cupboard, defined by the shoulder, cover or top.

The screws are pass-through, i.e. they pass through the box-shaped body and are screwed directly into the shoulder of the cupboard, whereas the plugs extend integrally and laterally from the box-shaped body made of plastic material and are pressure-inserted into a corresponding seat of the shoulder. A wall cupboard holder of the type briefly described above is described and illustrated, for example, in patents EP 0033179 Bl and EP 0632979 Al.

There are also other types of wall cupboard holders which substantially differ in the supports with which they are fixed to the cupboards and also in the means with which it is possible to regulate the positions in depth and height (inclination) of the rear hook.

These wail cupboard holders, described for example in EP 1228720 Bl, at present generally consist of a plate element equipped with a side flange which, in the assembly phase, is normally fixed by means of screws or expansion pegs in holes situated on the shoulder of the wall cupboard.

As mentioned above, the above known wall cupboard holders comprise a moveable hook element for fixing the cupboard to the wall which, as described in EP 1228720 Bl, is driven by screw-female screw mechanisms, possibly equipped with angular countershafts, capable of allowing the regulation of the rear position of the supporting hook (see also EP 0033179 Bl and EP 0632979 Al) .

Although these known wall cupboard holders are currently functional and satisfy the safety regulations in force in the field of hanging furniture items, in view of the present tendency to reduce the thicknesses of the panels forming wall cupboards and increasing diffusion of these pieces of furniture, which are also frequently overloaded, it can unfortunately happen that this cupboard/cupboard holder coupling is not always effective, long-lasting and above all safe.

As the stability of the wall cupboard depends on this constraint, unfortunately the wall cupboard frequently falls dangerously and/or breaks as a result of the shear forces acting in the wall cupboard holder coupling which are generated when the cupboard is loaded. The above drawbacks mainly occur in the wall cupboard holders of EP 0033179 Bl and EP 0632979 Al, with a box-shaped body made of plastic material.

A general objective of the present invention is to solve the above drawbacks of the known art in an extremely simple, economical and particularly functional manner. A further objective is to provide a visible wall cupboard holder group for anchoring a wall cupboard to the wall, which ensures an easy and firm assembly on any type of wall cupboard.

Another objective is to provide a visible wall cupboard holder group for anchoring a wall cupboard to the wall, which is capable of resisting high shear forces which can be generated in the cupboard/wall cupboard holder coupling once the cupboard has been loaded.

In view of the above objectives, according to the present invention, a visible wall cupboard holder group has been conceived for anchoring a cupboard to the wall, having the characteristics specified in the main claim and enclosed subclaims.

The structural and functional characteristics of the of the present invention, and its advantages with respect to the known art, will appear more evident from the fol- lowing description, referring to the enclosed schematic drawings, which illustrate examples of visible wall cupboard holder groups for anchoring a wall cupboard to the wall produced according to the innovative principles of the same invention.

With reference to the drawings, a visible adjustable wall cupboard holder group for anchoring a cupboard to the wall in question is indicated as a whole with 10.

Said wall cupboard holder group 10 visible in exploded form in figure 1 and suitable for effecting the anchoring of a wall cupboard 11 to a wall, is fixed dur- ing use on one side to a shoulder 12 of the relative wall cupboard 11 and on another, which at least partially protrudes externally from a hole 40 situated on a rear cover 13 of the same cupboard to a support (generally a metallic section) fixed to the wall (generally a metallic sec- tion) .

An example of these assembly phases and relative couplings of the wall cupboard holder 10 in both the rear hole 40 and in the side holes 41 of the wall cupboard 11 are shown in figures 7 and 8, whereas figures 7b and 8b illustrate the same wall cupboard holders 10 at the end of the assembly with the relative rear portions 15 protruding beyond the cover 13 of the wall cupboard 11.

As can be easily seen, according to an embodiment of the invention, there is also a covering top 100, general- Iy made of plastic, of the wall cupboard holder 10, which, however, has no structural function.

In particular, as clearly shown in figure 1, the wall cupboard holder 10 according to the invention com- prises a hooking element 14 to a supporting element fixed to the wall, said hook 14 is coupled at a first end 15' to a central portion 16 of a plate element whereas at a second end, which freely protrudes behind the central portion 16, there is a hook-shaped fixing portion 15 to the above support.

In order to allow regulations of the position of the hook-shaped portion 15, the connection of the hooking element 14 to the central portion 16 is of the adjustable type in depth F and inclination A. For this purpose, reg- ulation means 17, 17' of the depth F and inclination A of the hooking element 14 are envisaged, said means 17, 17' are associated with and easily accessible in the front to the central portion 16 ,

In this way, the user can proceed with all the regu- lations of the cupboard which he feels are necessary, in depth and height, as is well-known to experts in the field.

According to the invention, the wall cupboard holder 10 as described above, also comprises two side flanges 18, 18' which extend from the central portion 16 from opposite parts, above and below the hooking element 14, respectively, in which each of the two side flanges 18, 18' comprising fixing means 19, 19' of the wall cupboard holder group 10 to the inner side wall 12 (shoulder) of the wall cupboard 11, in addition to at least one element resistant to the shear forces 20, 20' which are generated when the wall cupboard holder 10 is assembled and when the wall cupboard is loaded. Said at least one element resistant to shear forces 20, 20' protrudes from the side flanges 18, 18' on the side facing the inner side wall 12 of the wall cupboard 11, and collaborates with the previous fixing means 19, 19' for a stable positioning of the wall cupboard holder 10 on an internal wall 12 of the wall cupboard 11.

As can be seen in figure 1, the regulation means 17, 17' of the depth F and inclination A of the hooking element 14, which, as already mentioned, are associated with and easily accessible in the front to the central portion 16, comprise two screw-female screw mechanisms.

In these mechanisms, there is a first regulation screw 30 which comprises a head which is firmly housed/entrapped in a counter- form 31 situated in the first portion 16 and a threaded development which is Ion- gitudinally associated in an internal threaded seat of the hooking element 14 in correspondence with the end 15' of the hooking element 14 opposite the hook 15.

As can be deduced from what is stated above, said first regulation screw 30 is able to regulate the longitudinal movement (depth) of the hooking element 14.

A second regulation screw 31 is also envisaged, which is associated with the first central portion 16 in a parallel and upper position with respect to the first regulation screw 30.

Said second regulation screw 31 acts on a movable circular lunette 33 situated at the opposite side with respect to the head of the second regulation screw 31 and is driven by the second regulation screw 31 to enforce a rotation of the hooking element 14 around a riveted pin 34.

According to an embodiment shown in figures 2 -2c, the elements resistant to shear forces 20, 20' comprise at least one plug element 20, 20' protruding from the side flanges 18, 18' which are coupled, not necessarily forcedly (i.e. not necessarily with interference), with holes 41 situated in the internal side wall 12 of the wall cupboard 11.

As shown in figure 2c, said plugs 20, 20' collabo- rate with the previous fixing means 19, 19', for example screws, for a stable positioning of the wall cupboard holder 10 on the internal side wall 12 of the wall cupboard 11, preventing the misalignment of the wall cup- board holder 10 with respect to the relative wall cupboard 11.

In the above embodiment, the plug elements 20, 20' are integrally positioned directly on the side flanges 18, 18' during the production of the wall cupboard holder 10, but alternatively they can also be produced separately and subsequently welded onto the side flanges 18, 18' as shown in the embodiment of figures 4 -4c.

The plug elements so far described are preferably hollow cylindrical plugs with a circular section but, al- ternatively, and in relation to the type of cupboard to be coupled with the wall cupboard holder 10, they can be hollow cylindrical plugs having a circumferential arc section as shown in the embodiments of figures 3 -3c.

As already specified, the fixing means 19, 19' can comprise at least one fixing screw 19, 19' of the side flanges 18, 18' to the internal side wall 12 of the wall cupboard 11 in which said at least one fixing screw 19, 19' can be coupled with the side flanges 18, 18' in different positions with respect to the at least one plug element 20, 20' through relative holes 44.

Alternatively, the above screws 19, 19' can be coupled with the side flanges 18, 18' inside the plug elements 20, 20' . According to another embodiment of the invention, the wall cupboard holder group 10 can comprise, as fixing means 19, 19', at least one expansion peg 21, 21' which can be optionally, but not necessarily, activated (radially expandable) by means of the screws 19, 19' and equipped with gripping teeth which, like the screws 19, 19' of the previous examples, fix the side flanges 18, 18' to the internal side wall 12 of the wall cupboard 11.

Said pegs 21, 21' can be coupled with the side flanges 18, 18' either in different positions with re- spect to the at least one plug element 20, 20', or, as shown in figures 5 -5c, coaxially with the relative screws

19, 19' to the at least one plug element 20, 20' .

Finally, according to a last embodiment, the fixing means comprise at least one expansion peg 21, 21' by means of cursors 22 with shaped heads which, like the previous pegs, fix the side flanges 18, 18' to the internal side wall 12 of the wall cupboard 11.

These pegs 21, 21' can also be coupled with the side flanges 18, 18' either in different positions or coaxial- Iy to the at least one plug element 20, 20' as shown in figures 6-6c.

From the above description with reference to the figures, it is evident how a visible wall cupboard holder group for anchoring a wall cupboard to the wall according to the invention is particularly useful and advantageous. The objective indicated in the preamble of the invention has therefore been achieved.

The visible adjustable wall cupboard holder 10 for the assembly of a wall cupboard to a wall according to the present invention, in fact, ensures an easy and firm assembly on any type of wall cupboard preventing any possible misalignment of the wall cupboard holder 10 itself with respect to the relative cupboard also when the latter is loaded.

This firm positioning can be obtained and maintained in any loading condition of the cupboard thanks to the presence of the elements resistant to shear forces 20, 20' protruding from the side flanges 18, 18' inserted in the holes 41 of the internal side wall 12 of the wall cupboard 11.

In this condition, said elements resistant to shear forces 20, 20' , such as cylindrical plugs, collaborate with the fixing means 19, 19', such as screws or expan- sion pegs and/or equipped with gripping teeth, to ensure a stable positioning of the wall cupboard holder group 10 on the internal wall 12 of the wall cupboard 11.

The forms of the visible wall cupboard holder group for the fixing of a wall cupboard to a wall, of the invention, as also the materials, can differ from those shown for purely illustrative and non-limiting purposes in the drawings .

The protection scope of the invention is therefore delimited by the enclosed claims.
